32 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
33 to avoid collisions with other libraries using same type names
36 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
38 * Added `prefer_ipv6' argument to the functions
39 silc_net_gethostbyname[_async]. If it is TRUE it will return

58 application does not need to define them. Affected file
59 includes/silcincludes.h.
61 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
62 old name went against naming convention. Applications now
63 include "silcclient.h" instead of "clientlibincludes.h".
64 Removed includes/clientlibincludes.h, it is redundant now.
66 * Renamed includes/version.h to silcversion.h.
68 * Added really preliminary support for OS/2 into the util
69 library. Only thread & mutex API is implemented, others

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

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

200 * Added new configuration options and blocks:
201 keepalive_secs, reconnect_count, reconnect_interval,
202 reconnect_interval_max, reconnect_keep_trying and
203 require_reverser_lookup. Added ConnectionParam block, and
204 implemented the connection parameters when connecting as
205 initiator and when accepting connections as responder.

213 algorithm parts and created new file silcalgs.conf, that
214 is now included from the example_silcd.conf.in.
216 * Optimized the silc_server_connect_to_router_second to take
217 the connection configuration object from the SilcServerConnection
218 object instead of finding it during the connecting phase.
219 Added the configuration object to SilcServerConnection struct.
220 Affected files silcd/server_internal.h, server.c.

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

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

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

352 the table with foreach callback. The current entry may
353 become invalid in the callback but it was referenced after
354 the callback returned.
356 Do not allow auto rehashing of hash table during the
357 silc_hash_table_foreach operation, for same reasons as it is
358 not allowed for SilcHashTableList. Affected files are
359 lib/silcutil/silchashtable.[ch].
361 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

382 users list to SilcHashTable. The affected files are
383 lib/silcclient/idlist.[ch].
385 * Fixed a bug in hash table tarversing. While the hash table
386 is traversed with SilcHashTableList the table must not be
387 rehashed. It is now guaranteed that auto rehashable tables
388 are not rehashed while tarversing the list. Also defined that
389 silc_hash_table_rehash must not be called while tarversing
390 the table. Added function silc_hash_table_list_reset that must
391 be called after the tarversing is over. The affected files are
392 lib/silcutil/silchashtable.[ch].
394 * Changed all hash table traversing to call the new
395 silc_hash_table_list_reset in server and in client library.
397 * Added function silc_client_on_channel to return the

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

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

563 Affected file silcd/command.c.
565 * Fixed silc_server_send_notify_kicked to send the kicker's
566 Client ID also, it was missing. Affected files are
567 silcd/command.c, silcd/packet_send.[ch].
569 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
571 * Do not save client history information in SERVER_SIGNOFF.
572 Fixes the bug in normal server that it does not detect
573 the client becoming valid after the server becomes back
574 online. Affected file silcd/server_util.c.
576 * Added `sock_error' field into the SilcSocketConnection
577 context. When error occurs during socket operation (read
578 or write) the error is saved. Added also new function
579 silc_socket_get_error to return human readable socket error
580 message. Affected files are lib/silcutil/silcsockconn.[ch],
581 lib/silcutil/unix/silcunixsockconn.c, and
582 lib/silcutil/win32/silcwin32sockconn.c.
584 * The server now prints the socket error message in the
585 signoff for client. Affected file silcd/server.c.
587 * Fixed the `created' channel information sending from router
588 to server in JOIN command. Checks now whether the channel
589 really was created or not and set it according that.
591 Fixed the JOIN command to use the client entry's current
592 ID during the joining procedure instead of the one it sent
593 in the command (it is checked though), since it can change
594 between the packet processing and command processing, and
595 would just case unnecessary pain in the client end. Affected
596 file silcd/command.c.
598 * Fixed a channel key payload sending to use correct channel
599 ID when the server was forced to change the channel's ID by
600 router. Router sent the key payload with the old Channel ID.
601 Affected file silcd/packet_receive.c.
603 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
605 * Call silc_server_save_channel_key only if the key payload
606 was provided in the JOIN command's command reply. Affected
607 file silcd/command_reply.c.
609 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
611 * Fixed silc_mp_sizeinbase to return the value correctly with
612 MPI. Affected file lib/silcmath/mp_mpi.c.
614 * Fixed the stop_server signal to correctly stop the scheduler
615 and gracefully stop the server when SIGTERM or SIGINT signals
616 are received. Affected file silcd/silcd.c.
618 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
620 * Simple handling of TERM and HUP signals. Also added some log
621 flushing call around. Affected file is
624 * Fixed small bugs in silclog.c. Now buffering output will take
625 effect after 10 seconds since startup: This will ensure that
626 no important startup messages are lost. Also output redirection
627 will preserve original format ([Date] [Type] message).
628 Affected file is lib/silcutil/silclog.c.
630 * Added two options to the config file, in the logging section:
631 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
632 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
634 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
636 * Do not print the warning about log files not being initialized
637 more than once to avoid excess logging. Affected file is
638 lib/silcutil/silclog.c.
640 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
641 the SIM copying in make install in Makefile.am.pre.
643 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
645 * Rewritten silclog APIs. Globally interesting changes follows:
646 silc_log_set_files() changed to silc_log_set_file().
647 silc_log_set_callbacks() changed to silc_log_set_callback().
648 ROBOdoc documented silclog header file.
649 SilcLogCb now returns bool to wether inihibit the default
650 handler or not (to keep the old behaviour return always TRUE).
651 The new APIs should also fix the problem of the
652 silcd_error.log file that was written in the current directory.
655 Log files streams will remain opened after silc_log_set_file()
656 call, means less CPU usage notably on high traffic servers.
657 File streams are now full buffered, and flushed to the disk
658 every 5 minutes, lesses HD activity and CPU usage.
659 Messages can be redirected, allowing admins to configure
660 one single logfile for all server messages.
661 the silc_log_quick global variable to activate fast-logging.
662 Affected files lib/silcutil/silclog.[ch]
664 * Changed some code to conform new silclog APIs. Affected
665 files are doc/example_silcd.conf.in, silcd/server.c
666 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
669 * Fixed a memory leak that could occur in some situations.
670 Affected file silcd/serverconfig.c.
672 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
674 * Added the silc_client_del_client to remove the client from
675 all channels as well. Affected file lib/silcclient/idlist.c.
677 * Fixed the client library to correctly remove the client
678 from all channels when the client entry is being destroyed.
679 Affected file lib/silcclient/client_notify.c, command.c.
681 * Added auto-nicking support to the client library. If the
682 applicatio now sets client->nickname it will be sent to the
683 server after connecting by the library. This way for example
684 SILCNICK (or IRCNICK) environment variables will have effect
685 and always change the nickname automatically to whatever
686 it is wanted. Affected file lib/silcclient/client.[ch].
688 * Renamed silc_server_command_bad_chars to the
689 silc_server_name_bad_chars and moved it to the
690 silcd/server_util.[ch]. Added also new function
691 silc_server_name_modify_bad to return nickname that
692 includes bad characters as new nickname without those
693 bad characters. This check and modify is now used in
694 silc_server_new_client when the username is initially set
695 as nickname, so it must be checked to be valid nickname.
696 Affected file silcd/packet_receive.c.
698 * The nickname length is now taken from the packet for real
699 and not trusted to strlen() since it clearly can return
700 wrong length for nickname including bad characters. This
701 also applies to channel names. Affected file silcd/command.c.
703 * Removed the lib/silcsilm/modules directory. Modules are now
704 compiled into the lib/silcsim. Fixed the copying of the
705 modules to follow symbolic links in Makefile.am.pre.
707 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
709 * Fixed silc_string_regexify list creation. Fixes bugs with
710 BAN and INVITE commands in server. The affected file is
711 lib/silcutil/unix/silcunixutil.c.
713 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
715 * Removed the command destructor entirely from the server's
716 command and command reply routines. It is not needed, and
717 its usage was buggy and caused crashes. Affected files are
718 silcd/command[_reply].[ch].
720 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
722 * Cancel protocol and NULL sock->protocol if timeout
723 occurred during protocol. Affected file silcd/server.c.
725 * Cancel protocol timeouts always before calling the final
726 callback, to assure that after final callback is called
727 no other state will be called for the protocol anymore.
728 Affected file silcd/protocol.c.
730 * Print error log if incoming connection configuration could
731 not be found. Affected file silcd/server.c.
733 * Fixed JOIN command to correctly save the founder mode
734 to the client on normal SILC server, when the channel
735 was created by the router. Affected file silcd/command.c.
737 * Fixed LIST command (hopefully) to send correct reply
738 packets. Affected file silcd/command.c.
740 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
742 * The silc_packet_receive_process now returns FALSE if the
743 read data was invalid packet, and TRUE if it was ok.
745 The server now checks that if unauthenticated connection
746 sends data and its processing fails the server will close
747 the connection since it could be a malicious flooder.
749 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
751 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
753 * Make sure the warning about error opening a log file is
754 printed only once and not everytime it fails (produces
755 too much useless log). Affected file lib/silcutil/silclog.c.
757 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
759 * Made the silc_server_daemonise() function more readable.
760 Affected file silcd/server.c.
762 * Pid file is now optional, the user may comment it out from
763 the config file. Removed define SILC_SERVER_PID_FILE, we
764 don't need a default any longer. Affected file
765 configure.in.pre, lib/Makefile.am.pre.
767 * Make some use of the pid file. The server now dies at startup
768 if it detects a valid pid file on his path. The server would
769 die anyway in this circumstance, because of the bind() failure.
770 Affected file silcd/silcd.c.
772 * No longer compiling lib/dotconf.
774 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
776 * Fixed JOIN command parsing not to crash. Affected file
777 lib/silcclient/command.c.
779 * Fied the NICK_CHANGE notify to add the new client entry
780 even it is resolved. This removes an <[unknown]> nick
781 thingy bug in the client. Affected file is
782 lib/silcclient/client_notify.c.
784 * Do not try to allocate 0 bytes (efence does not like it)
785 in lib/silccore/silccomand.c when encoding payload.
787 * Do not take IRCNICK as nickname in Irssi SILC client since
788 it is not possible to set nickname before hand connecting
789 the server (TODO has an entry about adding auto-nicking
792 * Changed the silc_server_command_pending to check whether
793 there already exists an pending entry with the specified
794 command, command identifier and pending callback. This is
795 to fix IDENTIFY and WHOIS related crashes that may register
796 multiple pending commands with same identifier. Affected
797 file silcd/command.c.
799 * Fixed the server to reconnect to the router even if it
800 was already reconnecting and EOF was received. This to
801 fix a possibility that the server wouldn't ever try to
802 auto-reconnect to the router. Affected file silcd/server.c.
804 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
806 * Fixed the server's password authentication to use the
807 length of the locally saved password, and not the one
808 sent in the packet. Affected file silcd/protocol.c.
810 * Fixed same password authentication problem in the
811 Authentication Payload handling routines in
812 lib/silccore/silcauth.c.
814 * Yet another password authentication problem fixed with
815 channel password handling in silcd/command.c.
817 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
819 * If first character of string in silc_parse_userfqdn is '@'
820 then do not parse it. Affected file is
821 lib/silcutil/silcutil.c.
823 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
825 * Fixed minor bug in IDENTIFY command reply sending, which
826 caused various weird problems during JOIN when it was
827 resolving names for users. Affected file silcd/command.c.
829 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
831 * Fixed the IDENTIFY command reply sending to chech better valid
832 clients. It was possible to send incomplete list of replies.
833 Affected file silcd/command.c.
835 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
837 * Added silc_client_command[s]_[un]register functions now to
838 dynamically register the commands in client library. Removed
839 the static table of commands. This allows the client library
840 to call commands without causing the application to know about
841 what commands library has called.
843 Removed the INFO command reply kludge to detect when the command
844 was called by library. Now library use its own command reply
845 function for INFO command.
847 Added function silc_client_command_call to call a command.
848 Application can use it to call command, not access the structure
851 Now all commands that are sent by the client library (not
852 explicitly sent by application) use own command reply functions.
854 Affected files around lib/silcclient/ and in
855 irssi/src/silc/core/.
857 * Fixed the WHOIS command reply sending to chech better valid
858 clients. It was possible to send incomplete list of replies.
860 Fixed the WHOIS and IDENTIFY to send the request to router
861 if normal server did not do it and did not find any results.
863 Affected file silcd/command.c.
865 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
867 * Moved the internal data from SilcClient context into its
868 own file, not accesible to application. Affected files
869 lib/silcclient/client.h and lib/silcclient/client_internal.h,
870 and other files in client library.
872 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
874 * Added doc/examples installation target in Makefile.am.pre.
877 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
879 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
880 commands the found client entry will be removed from the
881 cache, after notifying application about the error. Affected
882 file lib/silcclient/command_reply.c.
884 * Changed the /MSG to check for exact nickname user gave, and
885 not let `nick' match `nick@host' if it is only one found. Now,
886 user must type the exact nickname (like nick@host2) even if
887 there are no more than one same nicks found. This is to avoid
888 a possibility of sending nickname to wrong nickname since
889 `nick' could match `nick@host'. Affected file is
890 irssi/src/core/silc-servers.c.
892 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
894 * Do not print "you are now server operator" or similar when
895 giving /away command. Affected files are
896 irssi/src/silc/core/client_ops.c, silc-servers.h.
898 * Made the silc_server_command_pending_error_check to send
899 the same command reply payload it received back to the
900 original sender of the command. This way all arguments
901 that was received by the server will be received by the
902 client too. Affected file silcd/command.c.
904 * Added the silc_idcache_add to return the created cache entry
905 to a pointer. Affected file lib/silccore/silcidcache.[ch].
907 * Add global clients to expire if they are not on any channel.
908 This is because normal server will never know if they signoff
909 if they are not on any channel. The cache expiry will take
910 case of these entries. This is done by normal servers only.
911 The affected files are silcd/command_reply.c,
912 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
914 * If server receives invalid ID notification for WHOIS or
915 IDENTIFY and the ID exists in the lists, it is removed.
916 Affected file silcd/command_reply.c.
918 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
919 in client then client entry that it matches is searched and
920 the nickname is printed on the screen for user. Affected
921 file irssi/src/silc/core/client_ops.c.
923 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
925 * Use cache entry expire time in the LIST command reply to
926 purge old entries from the cache after the LIST command
927 reply has been received. This way we don't have non-existent
928 entries in the cache for too long. Affected file is
929 silcd/command_reply.c.
931 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
933 * If we are normal server, and we've not resolved client info
934 in WHOIS or IDENTIFY from router, and it is global client,
935 we'll check whether it is on some channel. If it is not
936 then we cannot be sure about its validity and will resolve it
937 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
938 file silcd/command.c.
940 * Search channel by name (if possible) rather than by ID
941 in IDENTIFY command's command reply. Affected file is
942 silcd/command_reply.c.
944 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
946 * Distribute to the channel passphrase in CMODE_CHANGE notify.
947 Updated specs and implemented it. Affected file silcd/command.c,
948 silcd/packet_send.c and silcd/packet_receive.c.
950 * Implemented the <founder auth> payload handling in the JOIN
951 command. If provided all conditions for channel joining
952 except requirement to provide correct passphrase can be
953 overrided by the channel founder. Updated the protocol specs.
954 Affected file silcd/command.c.
956 Added support for founder auth in JOIN command in client
957 library. Fixed the parsing of the JOIN command now to support
958 all options as they should be. The affected file is
959 lib/silcclient/command.c.
961 * Optimized the WHOIS and IDENTIFY commands to send the request
962 to router only if it includes nicknames or other names. If
963 they include only IDs then check the local cache first before
964 routing. Affected file is silcd/command.c.
966 * Added channels topic announcements. Affected file is
967 silcd/packet_receive.c and silcd/server.c.
969 * Fixed the silc_server_send_notify_topic_set to really destine
970 the packet to channel. Affected file silcd/packet_send.c.
972 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
973 library. Affected file lib/silcclient/client_notify.c.
975 * Added UMODE announcements. Affected file silcd/server.c.
977 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
979 * Memory leak fixes in:
981 lib/silcutil/silcsockconn.c
982 lib/silcske/silcske.c
985 lib/silccrypt/silcpkcs.c
986 lib/silccore/silccommand.c
987 lib/silccore/silcidcache.c
992 * ROBOdoc documented the lib/silcske/groups.h file and a
993 bit changed the interface for better.
995 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
997 * Update the client entry context in the ID cache after
998 nick change. Affected file lib/silcclient/command.c.
999 Fixes the CUMODE command when regaining founder privileges,
1000 and a little WHOIS problem.
1002 * Fixed silc_net_gethostbyname to correctly call the
1003 inet_ntop. Affected file lib/silcutil/silcnet.c.
1005 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1007 * Added IPv6 support checking to the configure.in.pre, added
1008 also --enable-ipv6 option to override the check. Affected
1009 file configure.in.pre.
1011 * The silc_thread_create now calls the start function
1012 directly if threads support is not compiled in. Removes
1013 ugly #ifdef's from generic code. Affected files are
1014 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1016 * Added silc_net_gethostby[name/addr]_async to asynchronously
1017 resolve. Affected files are lib/silcutil/silcnet.[ch].
1019 * Added support for rendering IPv6 based server, client and
1020 channel IDs. Affected file lib/silcutil/silcutil.c.
1022 * Added support for creating IPv6 based server IDs. Affected
1023 file is silcd/serverid.c.
1025 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1027 * Added silc_net_gethostby[addr/name] into the
1028 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1029 routines. Added silc_net_is_ip[4/6]. Affected file is
1030 lib/silcutil/unix/silcunixnet.c. All routines that take
1031 address as argument now supports both IPv4 and IPv6 addresses.
1033 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1035 * Fixed LIST command reply sending in server. Affected file
1038 * Server now sends the kicker's client ID in the KICK notify
1039 to the kicked client. Affected file silcd/command.c.
1041 * The client library now parses the kickers client ID and
1042 UI displays it. Affected files lib/silcclient/client_notify.c
1043 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1045 * Made all payload parsing function prototypes consistent.
1046 They all take now const unsigned char * and uint32 pair as
1047 the payload data instead of SilcBuffer. Changes all around
1048 the source tree. Other unsigned char* -> const unsigned char*
1049 changes around the tree as well.
1051 * Optimized SFTP client and server packet sending not to
1052 allocate new buffer for each packet but to recycle the
1053 first allocated buffer. Affected files are
1054 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1056 * Optimized the SFTP client to use SilcList instead of
1057 SilcDList for requests, because it is faster. Affected file
1058 is lib/silcsftp/sftp_client.c.
1060 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1061 into lib/silccore/silcid.[ch].
1063 Renamed silcpayload.[ch] into silcargument.[ch].
1065 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1067 * If client entry is deleted with active key agreement
1068 session, abort the session.
1070 The silc_client_abort_key_agreement now calls the completion
1071 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1073 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1076 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1078 * Don't use __restrict in older GCC's. Affected file is
1079 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1081 * silc_net_localhost now attempts to reverse lookup the
1082 IP/hostname. Affected file lib/silcutil/silcnet.c.
1084 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1085 command. It can be used to gain founder privileges at
1086 the same time when joining the channel.
1088 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1089 kicker's client ID as well. Updated protocol specs.
1091 Defined that the server must send SILC_COMMAND_IDENTIFY
1092 command reply with error status to client who sent
1093 private message with invalid client ID.
1095 Updated the protocol specification.
1097 * Added silc_server_send_command_reply to send any
1098 command reply. Affected file silcd/packet_send.[ch].
1100 * Added silc_id_payload_encode_data to encode ID payload
1101 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1103 * The server now send IDENTIFY command reply with error
1104 status if client ID in private message is invalid. Affected
1105 file silcd/packet_receive.c.
1107 * Save the server key file with server's IP address in
1108 the filename instead of hostname. The affected file is
1109 irssi/src/silc/core/client_ops.c.
1111 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1113 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1116 * Added libtool support for compiling shared objects in
1117 lib/silcsim. Affected file configure.in.pre and
1118 lib/silcsim/Makefile.am. Original patch by cras.
1120 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1122 * Pid file configuration, and server's config file fixes
1123 patch by toma. Updated CREDITS file.
1125 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1127 * Fixed silc_client_channel_message to not try to decrypt
1128 the message twice if it resolved the destination client
1129 information. This could cause of dropping one channel
1130 message. Affected file lib/silcclient/client_channel.c.
1132 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1134 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1135 lib/silcclient/client.c. This function is used when the SILC
1136 Client is run under some other scheduler, or event loop or
1137 main loop. On GUI applications, for example this may be
1138 desired to used to run the client under the GUI application's
1139 main loop. Typically the GUI application would register an
1140 idle task that calls this function multiple times in a second
1141 to quickly process the SILC specific data.
1143 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1145 * Fixed silc_server_drop() for dropping the supplementary
1146 groups as well, this could cause a security hole on some
1149 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1151 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1154 * Write PID file after dropping privileges. Added -F option
1155 to run server on foreground. A patch by debolaz.
1156 Affected files silcd/server.c, silcd/silcd.c.
1158 * Fixed MOTD to return the MOTD file server name. Affected
1159 file silcd/command.c.
1161 * Added INFO command reply handling to the Irssi SILC Client.
1162 Affected file irssi/src/silc/core/client_ops.c.
1164 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1166 * Fixed the silc_idcache_list_* routines to really support
1167 the dynamic list. Fixes a crash. Affected file is
1168 lib/silccore/silcidcache.c.
1170 * Fixed the LIST command reply to really call LIST command's
1171 pending callbacks. Affected file silcd/command_reply.c.
1173 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1175 * Update conn->local_entry->nickname after giving NICK
1176 command. Affected file lib/silcclient/command.c.
1178 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1180 * Added the [pid] option to the silcd configuration file
1182 Affected files: serverconfig.[ch] and silcd.c
1184 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1186 * Save fingerprint in WHOIS command reply in server.
1187 Affected file silcd/command_reply.c.
1189 * Fixed NICK commands pending callback registration.
1190 Affected file lib/silcclient/command.c.
1192 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1194 * Use ++server->cmd_ident when sending commands in server,
1195 instead of random number. Affected file silcd/command.c.
1197 * Fixed GETKEY command reply to call actually GETKEY pending
1198 command callbacks. Affected file silcd/command_reply.c.
1200 * A bit stricter check for nicknames. Check for same nickname
1201 in NICK command also. Affected file silcd/command.c.
1203 * Do not call INFO command everytime client ID changes, only
1204 during first connecting. Affected file lib/silcclient/client.c.
1206 * Set the new nickname only after successful command reply for
1207 NICK command is returned by server. Affected file
1208 lib/silcclient/command.c.
1210 * Remove nicknames from nicklist during server_signoff notify.
1211 Should fix /NAMES bit more. The affected file is
1212 irssi/src/silc/core/silc-channels.c.
1214 * Added `fingerprint' field to the SilcIDListData in the
1215 silcd/idlist.h to hold the fingerprint of the client's
1218 Send the fingerprint of the client's public key in WHOIS
1221 Affected files silcd/command.c, and silcd/idlist.[ch].
1223 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1224 create fingerprint from given data.
1226 * Show the fingerprint of the client's public key in WHOIS.
1227 Affected files irssi/src/module-formats.[ch] and
1228 irssi/src/silc/core/client_ops.c.
1230 * Format the multiple same nicknames also during JOIN and
1231 NICK_CHANGE notifys. Affected file is
1232 lib/silcclient/client_notify.c.
1234 * Do not print error on screen for invalid private message
1235 payload since it can come if someone is sending private
1236 messages with wrong key. Affected file
1237 lib/silccore/silcprivate.c.
1239 * Fixed multiple concurrent /PING crash. Affected file
1240 lib/silcclient/command.c.
1242 * Changed the wrong ID encoding. All IP addresses must be
1243 in MSB first order in encoded format. They were encoded
1244 wrong and was in LSB format. Affected files are
1245 silcd/serverid.c, lib/silcutil/silcutil.c.
1247 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1249 * Call the `connect' client operation through the scheduler
1250 in case of error. Affected file lib/silcclient/client.c.
1252 * Call the `failure' client operation even if the error
1253 occurred locally during a protocol. Affected file is
1254 lib/silcclient/protocol.c.
1256 * Added support of sending LIST command to router from normal
1257 server. This way normal server can get list of all channels
1258 in the network too. Fixed the channel list sending in the
1259 server too. Affected files are silcd/command.c, and
1260 silcd/command_reply.[ch].
1262 * Added silc_server_update_channels_by_server and
1263 silc_server_remove_channels_by_server. They are used during
1264 disconnection of primary router and in backup router protocol.
1265 Affected file silcd/server_util.[ch], silcd/server.c and
1266 silcd/server_backup.c.
1268 * Fixed channel adding to global list in IDENTIFY command
1269 reply in server. Affected file silcd/command_reply.c.
1271 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1273 * If the incoming packet type is REKEY or REKEY_DONE process
1274 that packet always synchronously. Fixes yet another MAC
1275 failed error on slow (dialup) connections. Affected file
1276 lib/silcclient/client.c and silcd/server.c.
1278 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1280 * Call check_version SKE callback for initiator too. Affected
1281 file lib/silcske/silcske.c.
1283 * Implemented fix for security hole found in the SKE that was
1284 fixed in the specification few days back; the initiator's
1285 public key is now added to the HASH value computation.
1286 Added backwards support for the old way of doing it too, for
1287 old clients and old servers. Affected file is
1288 lib/silcske/silcske.c.
1290 * Enabled mutual authentication by default in SKE. If initiator
1291 is not providing mutual authentication the responder will
1292 force it. This will provide the proof of posession of the
1293 private key for responder. The affected files are
1294 lib/silcclient/protocol.c and silcd/protocol.c.
1296 * Do not cache anymore the server's public key during SKE.
1297 We do mutual authentication so the proof of posession of
1298 private key is done, and if the server is authenticated in
1299 conn auth protocol with public key we must have the public
1300 key already. Affected file silcd/protocol.c.
1302 * Added new global debug variable: silc_debug_hexdump. If
1303 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1304 file lib/silcutil/silclog.[ch].
1306 * Fixed compilation warning due to char * -> const char *.
1307 Affected files lib/silcutil/silcnet.h, and
1308 lib/silccore/silcauth.[ch].
1310 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1312 * Fixed CMODE command when new channel key was created. If
1313 the creation failed the old key was removed. Next time giving
1314 same command would crash the server since the old key was
1315 freed already. Affected file silcd/command.c.
1317 * Fixed the silc_server_announce_get_channels to not crash
1318 on reconnect. Affected file silcd/server.c.
1320 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1322 * Added silc_log_set_debug_string function to set a regex
1323 string to match for debug output. Only the function names,
1324 or filenames matching the given debug string is actually
1325 printed. This way it is possible to filter out those debug
1326 strings that user is not interested in.
1328 Fixed a bug in silc_string_regexify.
1330 Affected files lib/silcutil/silclog.[ch], and
1331 lib/silcutil/unix/silcunixutil.c.
1333 * Changed the -d options in both server and Irssi SILC client
1334 to take the debug string as argument. Affected files
1335 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1337 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1339 * Added silc_hash_babbleprint to create a Bubble Babble
1340 Encoded fingerprint. The encoding is developed by Antti
1341 Huima (draft-huima-babble-01.txt), and it creates human
1342 readable strings out of binary data. Affected file
1343 lib/silccrypt/silchash.[ch].
1345 * Print the babble print now in addition of fingerprint as well
1346 in Irssi SILC client. Affected files are
1347 irssi/src/fe-common/silc/module-formats.[ch],
1348 irssi/src/fe-common/silc/core/client_ops.c.
1350 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1352 * Fixed a security problem found in SKE. The initiator's
1353 public key too is now added to the HASH hash value creation
1354 which is signed by the responder to create the SIGN value.
1355 This will prevent anyone in the middle to lie to the responder
1356 about the initiator's public key. If this is done now, the
1357 man in the middle will get caught. Updated the protocol
1360 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1362 * Better installation directory handling. Configure module
1363 paths and other paths automatically to example_silc* files
1364 in doc/. A patch by toma.
1366 * Fixed compiler warning from MPI library, and from SILC RNG.
1369 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1370 It can be configured with ./configure. A patch by toma.
1372 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1374 * Find correct make to use in prepare-clean. A patch by
1375 toma. Affected file prepare-clean.
1377 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1379 * Added irssi variables use_auto_addr, auto_bind_ip,
1380 auto_bind_port and auto_public_ip.
1382 * Changed the interface for silc_client_send_key_agreement
1383 in lib/silcclient/silcapi.h
1387 irssi/src/silc/core/silc-core.c
1389 lib/silcclient/silcapi.h
1390 irssi/src/silc/core/silc-channels.c
1391 lib/silcclient/client_keyagr.c
1394 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1396 * Added silc_pkcs_public_key_compare to compare two
1397 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1399 * Check that the client who set the founder mode on the
1400 channel is the same client that is giving the founder
1401 mode to itself. It is done by comparing the saved public
1402 key (it is saved even in the authentication is passphrase).
1403 Affected file silcd/command.c.
1405 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1407 * Do not process packet for disconnected socket connection.
1408 Affected file lib/silccore/silcpacket.c.
1410 * Process the DISCONNECT packet through scheduler in the
1411 client library. Affected file lib/silcclient/client.c.
1413 * Fixed the silc_client_packet_parse to not to increase
1414 the packet sequence number if the conn->sock and the
1415 current socket connection is not same. This can happen
1416 for example during key agreement when the conn includes
1417 multiple socket connections (listeners). Affected file
1418 lib/silcclient/client.c.
1420 * The sender of the file transfer request now provides also
1421 the pointer (listener) for the key exchange protocol. If
1422 the listener cannot be created then it sends empty key
1423 agreement and lets the receiver provide the listener.
1425 Added `local_ip' and `local_port' arguments to the
1426 silc_client_file_send. If they are provided they are used,
1427 if not then it will attempt to find local IP address, if
1428 not found or bind fails then the remote client will provide
1431 Affected files are lib/silcclient/client_ftp.c and
1432 lib/silcclient/silcapi.h.
1434 * Extended the FILE SEND command to support defining the
1435 local IP and port for key exchange listener. They are
1436 optional. Affected file irssi/src/silc/core/silc-servers.c.
1438 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1440 * Defined to WHOIS command reply the sending of fingerprint
1441 of the client's public key (if the proof of posession of the
1442 corresponding private key is verified by the server).
1443 Updated to the protocol specification.
1445 * Added support of receiving the client's public key's
1446 fingerprint in command reply in client library. Affected
1447 file is lib/silcclient/command_reply.c, and
1448 lib/silcclient/idlist.[ch].
1450 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1452 * Do not send over 128 chars long nickname to the server
1453 in NICK command. Affected file lib/silcclient/command.c.
1455 * Do not send over 256 chars long channel names to the server
1456 in JOIN command. Affected file lib/silcclient/command.c.
1458 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1460 * Assure that silc_server_close_connection cannot be called
1461 twice for same socket context. Affected file is
1464 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1466 * Send error message to application if opening file for
1467 writing during file transfer fails. Affected file is
1468 lib/silcclient/client_ftp.c.
1470 Remove all file transfer sessions for a client that we're
1471 removing from ID cache.
1473 Affected file is lib/silcclient/client_ftp.c.
1475 * Fixed silc_net_addr2bin to return correct address. Affected
1476 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1478 * Fixed file transfer session removing on signoff notify.
1479 Affected file irssi/src/silc/core/silc-servers.c.
1481 * Added the SilcClientFileError to be returned in the monitor
1482 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1483 Affected file lib/silcclient/silcapi.h.
1485 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1487 * Fixed a crash in silc_client_ftp_free_sessions and
1488 silc_client_ftp_session_free_client. Affected file
1489 lib/silcclient/client_ftp.c.
1491 * Added `disabled' field in the SilcChannelEntry in the server
1492 to indicate if the server entry is disabled. Affected file
1493 silcd/idlist.h, silcd/command[_reply].c.
1495 * SILC server adds now /var/run/silcd.pid everytime it is
1496 started. Affected file silcd/silcd.c.
1498 * Added silc_server_packet_send_clients to send a packet to
1499 the provided table of client entries. Affected file
1500 silcd/packet_send.[ch].
1502 * Fixed a crash in client resolving in client_prvmsg.c in
1503 client library. Affected file lib/silcclient/client_prvmsg.c.
1505 * Do not actually remove the client directly from ID cache
1506 during SERVER_SIGNOFF, but invalidate it. This way we
1507 preserve the WHOWAS info for the client. Affected file
1508 silcd/server_util.c.
1510 * Fixed SERVER_SIGNOFF notify handling in the server. The
1511 server is now able to process incoming SERVER_SIGNOFF notify
1512 for a server that it doesn't even know about. It will remove
1513 the clients provided in the notify. Affected file
1514 silcd/packet_receive.c.
1516 * Check for partial packet in data queue after every packet that
1517 was found from the queue. Return and wait for more data if
1518 there is partial data in queue. Affected file is
1519 lib/silccore/silcpacket.c.
1521 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1523 * Added SilcClietFileError enum to indicate error in
1524 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1525 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1526 Affected files lib/silcclient/silcapi.h and
1527 lib/silcclient/client_ftp.c.
1529 * Check that newsize in silc_buffer_realloc is larger than
1530 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1532 * Added better monitor of file transfers. It now monitors
1533 key agreement protocol during the file transfer too. Added
1534 error reporting too. Affected files
1535 irssi/src/silc/core/silc-servers.c,
1536 irssi/src/fe-common/silc/module-formats.[ch].
1538 * Wrote a help file for FILE command.
1540 * Added silc_rng_global_get_byte_fast to get not-so-secure
1541 random data as fast as possible. Random data is read from
1542 /dev/urandom if available and from the SILC RNG if not
1543 available. It is used in padding generation. Affected file
1544 lib/silccrypt/silcrng.[ch].
1546 * All packets in client library are now processed synchronously.
1547 Optimized packet processing a lot. Affected file
1548 lib/silcclient/client.c.
1550 * All server connection packets are processing synchronously
1551 now in server, to optimize packet processing. Affected file
1554 * Include files are installed now only in Toolkit distribution
1555 if make install is given. Affected files: all Makefile.am's.
1557 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1559 * Assure that silc_client_notify_by_server_resolve does not
1560 resolve the client information multiple times. If it cannot
1561 be found by the first it cannot be found at all. Affected
1562 file lib/silcclient/client_notify.c.
1564 * Fixed WHOWAS command reply calling. Affected file
1565 lib/silcclient/command_reply.c.
1567 * Removed all references to silc_idlist_get_client from the
1568 Irssi SILC client since that call is internal call used by
1569 the library. The Irssi SILC client will use now client
1570 retrieval functions found in silcapi.h.
1572 * Fixed a bug in resolving nickname info before sending
1573 private message. It used freed memory. Affected file
1574 irssi/src/silc/core/silc-servers.c.
1576 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1578 * Assure my_channels statistics cannot go negative in server.
1579 Affected files silcd/server.c, silcd/server_util.c.
1581 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1583 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1585 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1587 * Win32 Toolkit changes. Affected files
1588 win32/silc.dsw, win32/libsilc/libsilc.def,
1589 win32/libsilcclient/libsilc.def,
1590 lib/silcutil/silcutil.c, and
1591 lib/sftp/sftp_fs_memory.c.
1593 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1595 * Added silc_net_localip to return local host's IP address.
1596 Affected file lib/silcutil/silcnet.[ch].
1598 * If key exchange or rekey protocol is active for a connection
1599 parse all packets syncronously since there might be packets
1600 in packet queue that we are not able to process without first
1601 processing packets before them. Affected file silcd/server,
1602 lib/silcclient/client.c.
1604 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1605 whether library should continue processing the packet.
1606 Affected file lib/silccore/silcpacket.h.
1608 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1609 SilcSFTPMonitorData to SFTP server to monitor various
1610 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1611 lib/silcsftp/sftp_server.c.
1613 * Added silc_file_size to return file size. Affected file
1614 lib/silcutil/silcutil.[ch].
1616 * Implemented the file transfer support for the client library.
1617 Added preliminary support for simple client to client one-file
1618 transmission. Affected file lib/silcclient/client_ftp.c,
1619 lib/silccilent/client.[ch].
1621 * Added new local command FILE to the Irssi SILC Client.
1622 It is used to perform the file transfer. It has subcommands
1623 SEND, RECEIVE, SHOW and CLOSE. Affected files
1624 irssi/src/silc/core/client_ops.c,
1625 irssi/src/silc/core/silc-server.[ch].
1627 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1629 * Relay the SILC_PACKET_FTP in the server. Affected files
1630 silcd/server.c and silcd/packet_receive.c.
1632 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1634 * Renamed silc_file_read and silc_file_write to functions
1635 silc_file_readfile and silc_file_writefile. Added function
1636 silc_file_open and silc_file_close. Affected files
1637 lib/silcutil/silcutil.[ch].
1639 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1641 * Resolve the client info when received private message or
1642 channel message for a client which nickname we don't know.
1643 Affected files lib/silcclient/client_prvmsg.c and
1644 lib/silcclient/client_channel.c.
1646 * Do not crash in /KEY if client is not connected. Affected
1647 file irssi/src/silc/core/silc-channels.c.
1649 * Added SilcClientStatus field to the SilcClientEntry in the
1650 lib/silcclient/idlist.h.
1652 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1653 is incomplete and is being resolved, it won't be resolved
1656 Make sure also that USERS command reply does not resolve
1657 twice information. Affected file is
1658 lib/silcclient/command_reply.c.
1660 Make sure that silc_client_get_clients_by_list does not
1661 resolve twice same information.
1663 * Check for valid client->id in the silc_server_free_client_data.
1664 Affected file silcd/server.c.
1666 * Fixed /GETKEY nick@server not to crash if the server entry
1667 is not found. Affected file lib/silcclient/command.c.
1669 * Fixed the silc_server_check_cmode_rights to check the
1670 requested modes correctly. Affected file silcd/command.c.
1672 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1674 * Better checks for non-printable chars in nick added.
1675 Affected file silcd/command.c.
1677 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1679 * Call the silc_server_udpate_servers_by_server in the
1680 primary router that comes back online in the backup resuming
1681 protocol. Otherwise it routes packets wrong. Affected file
1682 silcd/server_util.[ch], silcd/server_backup.c.
1684 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1686 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1687 lib/silcutil/silcbuffmt.[ch].
1689 * Redefined the SILC packet header to include the padding
1690 length. Affected file lib/silccore/silcpacket.[ch].
1692 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1693 length for maximum padding up to 128 bytes). Affected
1694 file lib/silccore/silcpacket.h.
1696 * Removed all backwards support for old 0.5.x MAC thingies.
1697 The SILC packet header change makes it impossible to be
1698 backwards compatible.
1700 * Send the ENDING packet with timeout in the backup resuming
1701 protocol. This is to assure that all routers has connected
1702 to the primary router. Affected file silcd/server_backup.c.
1704 * Changed the RNG to take the first IV from random data. It
1705 used to take it from zero actually. Changed the RNG also
1706 to use /dev/urandom during session. /dev/random is used
1707 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1709 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1711 * Changed the SILC packet header to have the first two bytes
1712 (the packet length) encrypted. Affected files aroung the
1713 code tree, lib/silccore/silcpacket.[ch]. Removed the
1714 SilcPacketCheckDecrypt callback. It is not needed anymore
1715 since the silc_packet_receive_process will determine now
1716 whether the packet is normal or special.
1718 * Implemented the unidirectional MAC keys. Affected files
1719 lib/silcske/silcske.c, silcd/protocol.c and
1720 lib/silcclient/protocol.c.
1722 * Implemented the packet sequence number to the MAC computation.
1723 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1724 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1725 lib/silcclient/protocol.c.
1727 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1729 * Allow backup router to announce servers. All servers
1730 announced by backup router are added to the global list
1731 automatically. Update hte server's socket to our primary
1732 router also when backup router announces a server.
1733 Affected file silcd/packet_receive.c.
1735 * Do not update the client->router in the function
1736 silc_server_udpate_clients_by_server if the client is on
1737 global list. We might fail to find any specific server
1738 for locally connected clients and local cell clients. They
1739 should still use the `from' and not `to' as client->router.
1740 This fixes backup router resuming protocol. Affected file
1741 silcd/server_util.c.
1743 * Decrease channel statistics count only if the channel
1744 deletion worked. Affected files are silcd/server.c and
1745 silcd/server_util.c.
1747 * Added silc_server_update_servers_by_server to update origin
1748 of all server entries. Used during backup router protocol.
1749 Affected files silcd/server_util.[ch], silcd/server.c. and
1750 silcd/backup_router.c.
1752 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1753 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1754 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1755 lib/silccrypt/silchmac.c.
1757 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1759 * Assure that router cannot reroute the same channel message
1760 to the sender. Affected file silcd/packet_receive.c.
1762 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1764 * Made better checks that the channel message is not sent
1765 to the router it came from. Affected file is
1766 silcd/packet_send.c. Fixed memory leak too.
1768 * Announce informations for incoming router connection, but
1769 only after checking if it is replaced by backup router.
1770 Affected file silcd/packet_receive.c.
1772 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1774 * Fixed the backup resuming protocol to work in multiple
1775 router environment. Affected file silcd/server_backup.c.
1777 * Route packet only to one router in the function
1778 silc_server_packet_send_to_channel. Affected file is
1779 silcd/packet_send.c.
1781 * Fixed silc_server_send_notify_dest to set the broadcast
1782 flag. Fixed the silc_server_send_notify_topic to actually
1783 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1784 Affected file silcd/packet_send.c.
1786 * Changed the SFTP Filesystem interface. Changed the
1787 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1788 the filesystem operation function. The SilcSFTPFilesystem
1789 is now a context that is allocated by all filesystem allocation
1790 functions and it already includes the operations structure
1791 and filesystem specific context. It is given as argument
1792 now to the silc_sftp_server_start. This made the interface
1793 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1794 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1796 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1798 * Changed the backup router adding and getting interfaces
1799 in the server. The router that will be replaced by the
1800 specified backup router is now sent as argument. Affected
1801 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1804 * Added silc_net_addr2bin_ne to return the binary form of
1805 the IP address in network byte order. Affected files
1806 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1808 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1810 * Check for existing server ID in silc_server_new_server
1811 and in silc_server_connect_to_router_final and remove the
1812 old entry if it exists. Affected file silcd/packet_receive.c,
1815 * Send the channel message always to only one router, either
1816 in upstream or downstream. Affected file is
1817 silcd/packet_send.c.
1819 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1821 * Wrote the definition of the backup resuming protocol to the
1822 protocol specification.
1824 * Removed one redundant channel key generation from normal
1825 server during joining procedure. Removed one redundant
1826 channel key sending from server to router during joining
1827 procedure. Affected file silcd/command.c.
1829 * Made minor bugfixes to the backup router resuming protocol.
1830 Affected file silcd/server_backup.c, server.c.
1832 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1834 * Added --disable-asm configuration option. Affected files
1835 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1838 * Implemented the backup resuming protocol that is used to
1839 resume the primary router position in the cell after the
1840 primary router comes back online. Affected files
1841 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1842 and silcd/server_util.[ch].
1844 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1846 * Sleep two (2) seconds after sending QUIT command to server.
1847 Affected file lib/silcclient/command.c.
1849 * Assure that if outgoing data buffer is pending do not force
1850 send any data. Affected file silcd/packet_send.c.
1852 * Assure that if outgoing data buffer is pending do not force
1853 send any data. Affected file lib/silcclient/client.c.
1855 * Implemented the backup router support when the primary router
1856 goes down. The servers and routers can now use the backup
1857 router as new primary router without loosing connectivity.
1859 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1861 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1862 in the server to indicate disabled entry. All data read
1863 from the connection will be ignored and no data is sent
1864 for entry that is disabled. Affected files are
1865 silcd/idlist.h, silcd/server.c.
1867 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1869 * Created SFTP client and server test programs in the
1870 lib/silcsftp/tests directory.
1872 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * Implemented memory filesystem (virtual filesystem) for
1875 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1878 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1880 * Implemented the SFTP (SSH File Transfer Protocol) to the
1881 lib/silcsftp. It includes SFTP client and SFTP server
1884 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1886 * Moved lib/silccore/silcprotocol.[ch] to the
1887 lib/silcutil library.
1889 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1890 take variable argument list pointer as argument. Affected
1891 file lib/silcutil/silcbuffmt.[ch].
1893 * Added silc_buffer_set function that is used to set data
1894 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1895 Affected file lib/silcutil/silcbuffer.h.
1897 * Changed various routines in the core library to use the new
1898 silc_buffer_set instead of allocating new buffer only for
1901 * Added 64-bit value formatting and unformatting support to the
1902 silc_buffer_[un]format routines. Affected file is
1903 lib/silcutil/silcbuffmt.[ch].
1905 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1906 to includes/bitmove.h.
1908 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1910 * Fixed channel user mode saving in client library. Affected
1911 file lib/silcclient/command[_reply].c.
1913 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1915 * Defined the file transfer to the SILC Protocol. Added
1916 new packet type SILC_PACKET_FTP and defined File Transfer
1917 Payload. The mandatory file transfer protocol is SFTP
1918 (SSH File Transfer Protocol). Affected file in addition
1919 of the internet draft is lib/silccore/silcpacket.h.
1921 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1922 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1923 is used as part of backup router protocol when the primary
1924 router of the cell is back online and wishes to resume
1925 the position as primary router.
1927 * Redefined the MAC generation keys in the protocol. The
1928 same key is not used anymore in both direction. Both
1929 direction will now use different keys for sending and
1930 receiving. This fixes a potential security flaw. This
1931 change causes incompatibilities in the protocol.
1933 * Redefined also the MAC computation from the packet.
1934 An packet sequence number is now added to the MAC
1935 computation. This prevents possible replay attacks against
1936 the protocol. This change too causes incompatibilities
1939 Added `sequence' field to the SilcPacketContext to hold
1940 the current sequence number for the packet.
1942 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1944 * Added `created' field to the SilcIDListData in the file
1945 silcd/idlist.h to indicate the time when the entry was
1948 * Added `created' field to the SilcChannelEntry too. Affected
1949 file silcd/idlist.h.
1951 * Added `creation_time' aguments to all the announcement functions
1952 in the server. If it is provided then only the entries that
1953 was created after the provided time frame are actually
1954 announced. Affected file silcd/server.[ch].
1956 * The protocol says that the Channel ID's IP address must be
1957 based on the router's IP address. Added check for this in
1958 the silc_server_new_channel when processing incoming New Channel
1959 Payload. Affected file silcd/packet_receive.c.
1961 * Print out the correct version with --version in SILC client.
1962 Affected file irssi/src/silc/core/silc-core.c.
1964 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1966 * Fixed WHOWAS command to check for completnes of the client
1967 entry always, not just when the command is coming from client.
1968 Affected file silcd/command.c.
1970 * Added new function silc_server_packet_queue_purge to purge the
1971 outgoing data queue to the network. After the function returns
1972 it is guaranteed that the outgoing packet queue is empty.
1973 Affected file silcd/packet_send.[ch].
1975 * Purge the outgoing packet queue in the rekey protocol's final
1976 callback to assure that all rekey packets go to the network
1977 before quitting the protocol. Affected file silcd/server.c.
1979 * Added silc_client_packet_queue_parse as similar function as
1980 in server to the client library. The affected file is
1981 lib/silcclient/client.c.
1983 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1985 * Splitted silcd/server.c and created silcd/server_util.[ch]
1986 for utility functions.
1988 * Added new socket flag SILC_SF_DISABLED to indicate that the
1989 connection is open but nothing can be sent to or received from
1990 the connection. Affected file lib/silcutil/silsockconn.[ch].
1991 The checking for disabled socket is checked in the low level
1992 silc_socket_write and silc_socket_read functions.
1994 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1996 * Allow only nicknames and channel names that fits into the
1997 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1999 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2001 * When processing JOIN command reply in server check that if
2002 the channel exists in our global list we'll move it the local
2003 list. Affected file silcd/command_reply.c.
2005 * Fixed the check whether client is joined on the channel already
2006 in JOIN command. Affected file lib/silcclient/command.c.
2008 * Fixed the JOIN command reply to check whether the channel
2009 already exists. Affected file lib/silcclient/command_reply.c.
2011 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2013 * Added silc_ske_status_string to map the SKE error numbers
2014 to readable strings. The affected files are
2015 lib/silcske/silcske[_status].[ch].
2017 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2019 * Do not show the private channels on the WHOIS channel list
2020 as it is not allowed by the protocol. The affected file is
2023 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2025 * Assure that the packet length digged from the actual packet
2026 is something sensible in the silc_packet_decrypt_rest_special
2027 in lib/silccrypt/silcpacket.c.
2029 * Free and NULL the allocated pointer in silc_hmac_alloc if
2030 the HMAC allocation fails. The affected file is
2031 lib/silccrypt/silchmac.c.
2033 * Print the selected security properties to the log files in
2034 the server. Affected file silcd/protocol.c.
2036 * Add SKE's reference counter even if calling the completion
2037 callback manually. Otherwise it goes negative, although it
2038 does not cause any problems. The affected file is
2039 lib/silcske/silcske.c.
2041 * Remove the client entry with short timeout after giving the
2042 KILL command. Affected file lib/silcclient/command.c.
2044 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2045 case all found clients are already disconnected (WHOWAS would
2046 found them) in the server. Affected file silcd/command.c.
2048 * Update the last_receive (time of last data received) to be
2049 updated only when received private or channel message so that
2050 the idle time showed in WHOIS makes more sense.
2052 * Added boolean field `valid' in to the SilcClientEntry in the
2053 client library to indicate whether the entry is valid or not.
2054 This fixes the nickname change bug on channel when changing
2055 the nickname to be same than the old (like nick to Nick) the
2056 nickname formatter doesn't set the new nick anymore to Nick@host.
2057 Affected file lib/silcclient/idlist.[ch].
2059 * Now actually fixed the nickname changing on disconnection.
2060 Added new function silc_change_nick to the Irssi SILC Client.
2061 Affected file irssi/src/silc/core/client_ops.c,
2062 irssi/src/silc/core/silc-nicklist.[ch].
2064 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2066 * Check that the public key exists in the GETKEY command before
2067 trying to encode it. Affected file silcd/command.c.
2069 * Print some notifications on received public keys with GETKEY
2070 command in the Irssi SILC Client. Affected files are
2071 irssi/src/fe-common/silc/module-formats.[ch],
2072 irssi/src/silc/core/client_ops.c.
2074 * Use IDENTIFY command to resolve the server information in the
2075 GETKEY command instead of INFO command. Affected file
2076 lib/silcclient/command.c.
2078 * All command reply functions in the client library now calls
2079 the pending command reply callbacks even if an error has
2080 occurred. The server has done this a long time and now it was
2081 time to move the client library to this as well. Now all
2082 errors can be delivered back to the pending command reply
2083 callbacks if necessary. Affected files are
2084 lib/silcclient/command[_reply].[ch].
2086 * Change the nickname on disconnection back to the username
2087 because in reconnect the server will enforce it to it anyway.
2088 Affected file irssi/src/silc/core/silc-servers.c.
2090 * Fixed a config file parsing bug in the Irssi SILC client.
2091 Affected file irssi/src/silc/core/clientconfig.c.
2093 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2095 * When printing the channel mode on JOIN, verify that the
2096 channel key and channel's HMAC are valid. Affected file
2097 irssi/src/silc/core/client_ops.c.
2099 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2101 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2102 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2103 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2105 * Removed channel key rekey task deleting from the function
2106 silc_server_save_channel_key. Affected file silcd/server.c.
2107 Added explicit timeout task context instead that is used to
2108 delete the task if we are registering a new task before the
2109 new task has elapsed.
2111 * When channel key rekey occurs the client library now saves
2112 the old channel key for a short period of time (10 seconds) and
2113 is able to use it in case some is still sending channel
2114 messages encrypted with the old key after the rekey. Affected
2115 file lib/silcclient/[idlist.h|client_channel.c].
2117 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2119 * Added check to the silc_server_new_id_real to not accept
2120 new ID if it is the sender's own ID. Affected file is
2121 silcd/packet_receive.c.
2123 * Assure that we do not announce ourself or the one we've
2124 sending our announcements when we're router and are announcing
2125 servers to our primary router. Affected file silcd/server.c.
2127 * Fixed silc_server_command_identify_check_client to assemble
2128 correct WHOIS packet. It send corrupted WHOIS packet and
2129 caused problem with router to router connections. Affected
2130 file silcd/command.c.
2132 Fixed also silc_server_command_whois_check the same way
2133 as for the IDENTIFY command.
2135 * Added new SilcIDListStatus to the server in the SilcIDListData
2136 structure. The status now includes the current status of
2137 the entry (like registered, resolved etc.). Affected file
2138 silcd/idlist.[ch]. Defined a bunch of different status types
2139 as well. This replaced the old boolean registered field as well.
2141 Added resolve_cmd_ident field to the SilcClientEntry structure
2142 too so that if the entry is for example being resolved so
2143 another command may attach to the same pending command reply
2144 without requiring to resolve the same entry again. This concept
2145 should optimize the WHOIS and the IDENTIFY resolving under
2146 heavy load by taking away unnecessary resolving for entries
2147 that are being resolved already.
2149 Added support for adding multiple pending commands for one
2150 command idenfier. Affected file silcd/command[_reply].[ch].
2152 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2153 before deleting the data. Otherwise the hash table will have
2154 freed data in comparison functions. Affected file is
2155 silcd/command_reply.c.
2157 * Fixed silc_idlist_replace_client_id to add the new entry to
2158 the cache with NULL nickname. Otherwise there will be invalid
2159 memory as the nickname after the nickname is freed. Affected
2160 file silcd/packet_receive.c.
2162 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2163 saved into wrong slots because the previous number of entries
2164 was not taken into account. Affected file silcd/idlist.c.
2165 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2167 * If we are router and we receive JOIN notify to a channel that
2168 does not have any users then notified client is marked as the
2169 channel founder, as it is it. The affected file is
2170 silcd/packet_receive.c
2172 * Added to the extended hash table API's table_del_*ext functions
2173 the destructor as argument too, so that the caller can decide
2174 which destructor to use or whether to use destructor at all.
2175 Affected file lib/silcutil/silchashtable.[ch].
2177 * Fixed ID Cache purging. It actually deleted the entries from
2178 the hash table after the data was freed. The hash table ended
2179 up comparing freed memory. The affected file is
2180 lib/silccore/silcidcache.c.
2182 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2184 * Fixed Irssi SILC client's KILL command's HELP syntax.
2186 * The USERS command now resolves the detailed user information
2187 if the userinfo field is missing. Affected file is
2188 lib/silcclient/command_reply.c.
2190 * Do not print error in silc_file_read if the read file does
2191 not exist. Just silently return NULL. Affected file is
2192 lib/silcutil/silcutil.c.
2194 * Fixed the silc_log_output to not wine about NULL filename
2195 and to not create some bogus " " filename. Affected file is
2196 lib/silcutil/silclog.c.
2198 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2200 * Fixed various printing bugs on the user interface in the
2201 Irssi SILC Client. Minor changes that were forgotten from
2204 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2206 * Fixed the configure.in.pre and the compilation and distribution
2207 environment to support the new autoconf 2.52. That version is
2208 now required to compile the CVS trunk.
2210 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2212 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2213 to generally parse user@fqdn format strings. Affected file
2214 lib/silcutil/silcutil.c.
2216 * Added nickname_format and nickname_force_format fields to the
2217 SilcClientParams structure. The first one defines the format
2218 for the nicknames that the library will enforce if the receives
2219 multiple same nicknames. The second one is boolean value and
2220 can be used to force the library to always enforce the format
2221 to the nicknames regardles whether there are multiple nicknames
2222 or not. This configurable formatting was employed to flexibly
2223 support accessing multiple nicknames from the user interface.
2224 The userinterface can now set the nicknames to what ever format
2225 they prefer. Affected file lib/silcclient/silcapi.h.
2227 Added function silc_client_nickname_format to the file
2228 lib/silcclient/idlist.c. It performs the nickname formatting.
2230 Added new field `hostname´ to the SilcClientEntry context.
2231 It holds the hostname of the client. Affected file is
2232 lib/silcclient/idlist.h.
2234 * Irssi SILC Client sets the nicknames in nick@hostn format.
2235 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2236 irssi/src/silc/core/silc-core.c.
2238 The WHOIS printing now also shows both the real nickname and
2239 the formatted nickname so that user knows how to access the
2240 user if there are multiple same nicknames cached. Affected
2241 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2242 printing formatting too to take the hostname now as a separate
2243 argument. The Affected file is
2244 irssi/src/fe-common/silc/modules-formats.[ch].
2246 * Changed the silc_client_get_clients_local to accept the formatted
2247 nickname as argument. It accepts the real nickname too but the
2248 formatted nickname can be used to find the true entry from
2249 multiple entries. Affected file lib/silcclient/silcapi.h and
2250 lib/silcclient/idlist.c.
2252 * Added nickname_format_parse field to the SilcClientParams.
2253 It is a callback function provided by the application to parse
2254 the nickname out of the formatted nickname string. The library
2255 calls it to get the nickname from the formatted string. Since
2256 the application generally knows better the format of the nickname
2257 string it parses it instead of the library, even though library
2258 encodes the formatted string. If the callback function is not
2259 provided then the library will use the string as is. The
2260 affected file is lib/silcclient/silcapi.h.
2262 * All the nickname strings passed to the client library in
2263 commands are now expected to be formatted nickname strings.
2264 If the command does not support the formatted nickname string
2265 it will assume that the sent string is the actual nickname.
2266 Affected file lib/silcclient/command.c.
2268 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2270 * Added public key authentication support to OPER and SILCOPER
2271 commands in the client library. Affected file is
2272 lib/silcclient/command.c.
2274 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2276 * Changed the get_auth_methdod client operation to be asynchronous.
2277 It can be async if the application resolves the authentication
2278 method from the server during the negotiation. Added new
2279 SilcGetAuthMeth completion callback that the application will
2280 call after resolving the authentication method.
2282 Added function silc_client_request_authentication_method that
2283 the application can use to resolve the authentication method
2284 from the server. Added also SilcConnectionAuthRequest callback
2285 that the library will call after the server has replied. The
2286 application can call this function if it does not know the
2287 current authentication method.
2289 Affected files are lib/silcclient/client.c and
2290 lib/silcclient/silcapi.h.
2292 * The Irssi SILC client now automatically resolves the authentication
2293 method incase any configuration information is not present (and
2294 currently there never is). The affected file is
2295 irssi/src/silc/core/client_ops.c.
2297 * Fixed public key authentication from the client library.
2298 Affected file lib/silcclient/protocol.c. Changed also the
2299 protocol specification about the public key authentication in
2300 the connection authentication protocol. The actual data to be
2301 signed is now computed with a hash function before signing.
2303 * Fixed the public key authentication from the server as well.
2304 Affected file silcd/protocol.c.
2306 * Removed the mlock()'s from the memory allocation routines.
2307 Affected file lib/silcutil/silcmemory.c. The ./configure does
2308 not check anymore for the mlock(). Affected file is
2311 * Fixed USERS command in server to allow the execution of the
2312 command for private and secret channels if the client sending
2313 the command is on the channel. Affected file silcd/command.c.
2315 * Fixed silc_client_get_clients_local to return the clients
2316 count correctly. It could return wrong value. Affected file
2317 lib/silcclient/idlist.c.
2319 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2321 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2322 types. The assembler optimizations seemed not to like 64-bit
2323 data types. The assmebler optimizations thus are now enabled
2324 also for BSD systems as opposed to only enable them for Linux.
2326 * Do not check for threads at all on BSD systems. Affected
2327 file configure.in.pre.
2329 * Removed -n and -h options from the Irssi SILC Client since
2330 they are not used in silc.
2332 * Fixed the prime generation to assure that the first digit
2333 of the generated random number is not zero since our conversion
2334 routines does not like number strings that starts with zero
2335 digit. If zero digit is seen the random number is regenerated.
2336 This caused some corrupted RSA keys when the zero first digit
2337 was met. Affected file lib/silcmath/silcprimegen.c.
2339 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2341 * Fixed WIN32 configuration in the ./configure script.
2342 Fixed to include xti.h on environments that has it.
2343 Patches by Carsten Ilchmann and andrew.
2345 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2347 * Changed the silc_id_create_client_id to be collision
2348 resistant. It is now assured that there cannot be created
2349 two same client ID's. I suspect that some weird bugs in
2350 the server were actually caused by duplicate Client IDs.
2351 Affected file silcd/serverid.[ch]. A router receiving
2352 new ID now also assures and informs the sending server
2353 if the ID caused collision.
2355 * Changed the silc_id_create_channel_id to also assure that
2356 there are no collisions.
2358 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * Statement about ignoring the Mutual Authentication flag when
2361 performing rekey with PFS was a bit misleading. It is ignored
2362 if it was set in the initial negotiation, it cannot be even
2363 set in the rekey. Fixed in the ke-auth draft. Started the
2364 new versions of the protocol drafts in the doc/.
2366 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2368 * Fixed a bug in silc_client_command_identify_save when saving
2369 new channel information. The channel name was no duplicated
2370 and caused crash on exit. Affected file is
2371 lib/silcclient/command_reply.c.
2373 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2375 * Fixed the getkey command handling in the server. Send just
2376 empty OK reply to the sender if the key could not be fetched
2377 (but everything else was ok, like the key just was not available).
2378 Changed the public key parameter to optional in the protocol
2379 specs so that empty OK reply can be sent. Affected file
2382 Added a message to Irssi SILC client to tell to user if the
2383 server did not return a public key.
2385 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2387 * Fixed a channel key regeneration bug. It registered new
2388 timeout tasks exponentially until all system resources were
2389 used. Affected file silcd/server.c.
2391 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2393 * Added the SILC Document generator to the scripts/silcdoc.
2394 It can be used to generate the Toolkit Reference Manual out
2395 of the source tree. Internally it will also use the RoboDoc
2396 generator now imported in util/robodoc.
2398 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2400 * Added couple of return's in rekey protocol if error orccurred
2401 during the protocol. The execution must be terminated.
2402 Affected file silcd/protocol.c. Also, terminate the protocol
2403 always with timeout.
2405 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2407 * The client's Client ID was created initally from the wrong
2408 nickname (it could have been in format nick@host) in the
2409 silc_server_new_client. Affected file silcd/packet_receive.c
2411 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2413 * Added some SILC_LOG_ERROR's to various error conditions
2414 if client could not be added to ID cache. Affected files
2415 silcd/packet_receive.c and silcd/server.c.
2417 * When client's sock->user_data is freed, NULL also the
2418 client->router and client->connection pointers. Added check
2419 for these pointers being NULL to various places around the
2420 code. Affected file silcd/server.c.
2422 * Added client->data.registered == TRUE checks to various
2423 places around the code to assure that unregistered client's
2424 are not handled when it is not allowed. Affected file
2427 * Added `bool registered' fields to all
2428 silc_idlist_[server|client]_get_* routines to indicate whether
2429 the fetched client needs to be registered or not. Affected
2430 file silcd/idlist.[ch].
2432 * Add your own entry as registered to the ID cache in the
2433 server. Affected file server.c.
2435 * Fixed a bug in silc_server_new_server. The SilcServer was
2436 set as the new server's context instead of SilcServerEntry.
2437 This naturally caused some weird bugs.
2439 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2441 * Do not delete the channel rekey task when adding it
2442 for in silc_server_create_channel_key.
2444 * Changed the silc_server_create_channel_key to return
2445 TRUE or FALSE to indicate the success of the channel key
2448 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2450 * Fixed MSVC++ project files and added missing files to
2451 Makefiles under win32/.
2453 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * Do not add TCP_NODELAY flag if the operating system
2456 does not have it defined. Affected files are
2457 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2459 * Fixed buffer overflow from Irssi SILC Client. Affected
2460 file irssi/src/fe-common/core/themes.c.
2462 * Fixed double free in client library in the file
2463 lib/silcclient/client.c when disconnecting from server.
2465 * Applied double free patch from cras to Irssi SILC client.
2466 Affected files irssi/src/core/[modules/expandos].c
2468 * Fixed the disconnection handling to Irssi SILC Client.
2469 The application must call silc_client_close_connection
2470 in ops->connect client operation in case of failure of
2471 the connection. Affected file is
2472 irssi/src/silc/core/client_ops.c.
2474 * Do not set sock->protocol to NULL in the function
2475 silc_client_close_connection after executing the protocol's
2476 final callback since the sock might not be valid anymore.
2477 Affected file lib/silcclient/client.c.
2479 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2481 * Do not enable SILC_THREADS if the linking with libpthread
2482 did not happen. Affected file configure.in.pre.
2484 * Added notion to protocol specification that server must
2485 verify the sent authentication payload with CMODE when
2486 setting the channel founder key. Implemented it to the
2487 server. Affected file silcd/command.c.
2489 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2491 * Added _EXTRA_DIST SILC distribution variable to the
2492 distributions file. It is used to conditionally add extra
2493 files or directories to the specific distribution. Affected
2494 files ./prepare, Makefile.am.pre and distributions.
2496 Removed the `_' from the start of the distribution names.
2499 * Added README.WIN32 for instructions to compile the Toolkit
2502 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2504 * Fixed a double free in disconnection in the server. Affected
2505 file is silcd/server.c.
2507 * Fixed the lib/silcske/groups.c to work now also with GMP
2508 MP library. The string conversion did not work when using
2509 specific base and the base is indicated in the string as well.
2511 * Created win32/ directory which now includes MSVC++ specific
2512 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2513 It will appear only in the toolkit distribution
2515 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2517 * Changed the key material distribution function in case when
2518 the hash output is too short. The data is now concatenated
2519 a bit differently than it used to. Made the change to the
2520 SKE protocol specification.
2522 * Added better GMP detection to configure.in.pre. A patch
2525 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2527 * Fixed a minor bug in SKE that might cause some problem on
2528 some platforms. Affected file lib/silcske/silcske.c.
2530 * Added the cookie checking for initiator in the SKE. It checks
2531 that the responder returns the sent cookie unmodified. The
2532 affected file is lib/silcske/silcske.c. Added new SKE
2533 error type INVALID_COOKIE that can be sent during the
2534 negotiation. Fixed some memory leaks as well.
2536 * Added the "invalid cookie" error message to Irssi SILC client's
2539 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2541 * Added `task_max' field to the SilcClientParams to indicate
2542 the maximum tasks the scheduler can handle. If set to zero,
2543 default values are used. Affected file lib/silcclient/silcapi.h.
2545 * Fixed memory leaks in silc_client_close_connection. Affected
2546 file lib/silcclient/client.c.
2548 * Added silc_client_del_client_entry to client library to free
2549 all memory of given client entry. Affected file is
2550 lib/silcclient/idlist.[ch].
2552 * Added new functions silc_client_del_channel and
2553 silc_client_del_server to delete channel and server entries.
2554 Affected file lib/silcclient/[silcapi.h/idlist.c].
2556 * Removed silc_client_del_client_by_id from silcapi.h.
2558 * Fixed the INFO command to return the server's own info
2559 correctly when querying by Server ID. Affected file is
2562 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2564 * Removed the non-blocking settings in WIN32 code in the
2565 silc_sock_[read/write] and added SleepEx instead. Affected
2566 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2567 of input data is now checked with FIONREAD and ioctlsocket.
2569 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2571 * Call silc_schedule_task_del_by_context in the
2572 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2573 Affected file lib/silccore/silcprotocol.c.
2575 * Call silc_protocol_cancel for active protocols in the
2576 silc_server_close_connection if the funtion
2577 silc_server_free_sock_user_data has not been called.
2578 Affected file silcd/server.c.
2580 * Generic tasks cannot be deleted using the del_by_fd
2581 task deleting function since generic tasks does not match
2582 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2584 * Added a notion to SILCOPER help file that the SILCOPER works
2585 only on router server, not on normal server.
2587 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2589 * Added for WIN32 support for the new scheduler as well.
2590 Affected file lib/silcutil/win32/silcwin32schedule.c.
2592 * Fixed the SHA1 implementation to work on various platforms.
2594 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2596 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2597 API. It is part of the scheduler now. Everything else is
2598 as previously but some functions has changed their names.
2599 Checkout the lib/silcutil/silcschedule.h for the interface.
2600 Updated all applications to use the new interface. Affected
2601 files are lib/silcutil/silcschedule.[ch].
2603 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2605 * Found a bug in the SKE implementation. The HASH value,
2606 specified by the protocol, was not computed correctly. The
2607 public key of the responder was not added to the computation
2608 even though it is mandatory. Affected file lib/silcske/silcske.c.
2609 This unfortunately causes incompatibilities with older
2610 clients and servers.
2612 * Added WIN32 specific network init and uninit functions:
2613 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2614 the Winsock2. Affected file lib/silcutil/silcnet.h and
2615 lib/silcutil/win32/silcwin32net.c.
2617 * Set the socket always to nonblocking mode on WIN32 after
2618 reading data or writing data. Affected file is
2619 lib/silcutil/win32/silcwin32sockconn.c.
2621 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2623 * Fixed various compilation problems under WIN32. Affected
2624 files lib/silcutil/win32/silcwin32thread.c and
2625 lib/silcutil/win32/silcwin32schedule.c.
2627 * Removed all _internal.h #includes from public header
2628 files. Internal headers must never be included from
2631 Removed also the lib/silcske/payload_internal.h file.
2633 * All include files that may be needed (public and some others
2634 included by the public headers) by application developers are
2635 now copied to the ./includes directory. It does not copy any
2636 internal headers. Affected file Makefile.defines.pre and all
2637 Makefile.am's under lib/ and subdirs.
2639 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2641 * Do not change the ~/.silc directory's permissions automatically.
2642 Affected file irssi/src/silc/core/clientutil.c.
2644 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2646 * Do not cancel the protocol in silc_server_close_connection
2647 it might cause recursion. Now cancelled in the function
2648 silc_server_free_sock_user_data. Affected file silcd/server.c.
2650 * Fixed the silc_server_remove_clients_by_server to regenerate
2651 the channel keys correctly finally. Added also new function
2652 silc_server_remove_clients_channels to actually do it.
2653 Affected file silcd/server.c.
2655 * Fixed the silc_server_new_channel to not crash by giving
2656 wrong router to the new channel. Affected file is
2657 silcd/packet_receive.c.
2659 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2661 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2662 which is given as argument to the silc_client_alloc now.
2663 It can be used to configure the client and set various parameters
2664 that affect the function of the client.
2666 * The USERS command in server did not check whether the channel
2667 is private or secret. Affected file silcd/command.c.
2669 * Added new argument to the USERS command in protocol specification.
2670 The USERS command now can take the channel name as argument
2671 as well. Added support for this in client and server and
2672 updated the protocol specs.
2674 * Completed the GETKEY command in client. It can be now used
2675 to fetch also servers public key not only some clients.
2676 Affected files lib/silcclient/command[_reply].c.
2678 * Added silc_client_get_server to return server entry by the
2679 server name. Affected files lib/silcclient/silcapi.h and
2682 * Redefined the IDENTIFY command in protocol specification to be
2683 more generic. It now can be used to query information about
2684 any entity in the SILC Network, including clients, servers and
2685 channels. The query may be based either the entity's name
2686 or the ID. Added support for this in both client and server.
2688 Affected files silcd/command.c and lib/silcclient/command.c
2689 and command_reply.c.
2691 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2692 the _from_client and _from_server functions. Affected file
2695 * Added silc_client_get_channel_by_id_resolve to the file
2696 lib/silcclient/silcapi.h to resolve channel information by
2697 its ID. Added also silc_client_get_channel_by_id that
2698 does not resolve it from the server.
2700 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2702 * Added SilcServerEntry context into the client library
2703 to represent one server. The INFO command now allocates
2704 these to save the resolved server info. For now on the
2705 client library will also keep information about servers,
2706 connected and resolved with INFO.
2708 The INFO command now allocates the SilcServerEntry context
2709 and saves the server info there. The COMMAND_REPLY in
2710 the INFO now returns the parameters to application in
2711 same order as defined in the protocol specification.
2713 The entries are cached in the client->server_cache.
2715 * The INFO command is now issued after received the Client ID
2716 from the server. Affected file lib/silcclient/client.c.
2718 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2719 to the application as the mode changer might be server.
2720 It is guaranteed that NULL is not returned anymore to the
2721 application. Affected file lib/silcclient/client_notify.c.
2723 The ID Type is now also passed to the application so that
2724 it can check whether the returned entry is SilcClientEntry
2727 Added new function silc_client_get_server_by_id to return
2728 the server entry by ID. Affected files are the
2729 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2731 * Do not create the channel in the Irssi SILC Client when issuing
2732 the JOIN command but when received the sucessful JOIN command
2733 reply. Otherwise the channel might get created even though we
2734 could not join it. The Affected file is
2735 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2737 * Fixed a channel joining bug in router. The router must also
2738 check the channel modes, invite and ban lists etc. when serving
2739 the JOIN command sent by normal server. Affected file is
2740 silcd/command.c. The router now resolves the client's
2741 information from the server who sent the JOIN command if it
2742 does not know it, and processes the JOIN command only after
2745 * Changed the SilcCommandCb to take new argument; void *context2.
2746 Affected file lib/silccore/silccommand.h
2748 The second argument in the command callbacks in the server now
2749 includes the SilcServerCommandReplyContext if the command was
2750 called as pending command callback from the command reply.
2751 Otherwise it is NULL. When called as pending the status of the
2752 command reply will be checked and if it was erronous the
2753 error will be sent to the original sender of the command.
2754 This way the client always receives the error messages even
2755 though the server was actually the one who received the error
2756 when it resent the command to router, for example. Affected
2757 files silcd/command[_reply].[ch].
2759 * Fixed sending WHOWAS command's error message to client if
2760 the requested client could not be found. It was missing.
2763 * Changed the CMODE and CUMODE commands reply arguments in the
2764 protocol specification. The Channel ID is now sent in both
2765 of the commands to identify the channel. Implemented this
2766 new feature to the client and server. Affected files
2767 lib/silcclient/command_reply.c and silcd/command.c.
2769 * Made better checks for invite and ban lists in the JOIN
2770 command in server. Affected file silcd/command.c.
2772 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2774 * The server now performs the incoming host IP/DNS lookup
2775 using the silc_socket_host_lookup and thus does not block
2776 the server anymore. Affected file silcd/server.c.
2778 * Completed the multi-thread support for SILC Scheduler in
2779 the lib/silcutil/silcschedule.c.
2781 * Fixed the configure.in.pre to detect the pthread correctly
2784 * Fixed a deadlock in silc_task_queue_wakeup in the file
2785 lib/silcutil/silctask.c.
2787 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2789 * Added new function silc_schedule_wakeup that is used in
2790 multi-threaded environment to wakeup the main thread's
2791 schduler. It needs to be used when a thread adds a new task
2792 or removes a task from task queues. After waking up, the
2793 scheduler will detect the task queue changes. If threads
2794 support is not compiled in this function has no effect.
2795 Implemented the wakeup mechanism to both Unix and WIN32
2796 systems. Affected files are lib/silcutil/silcschedule.[ch],
2797 lib/silcutil/unix/silcunixschedule.c and the
2798 lib/silcutil/win32/silcwin32schedule.c.
2800 * Added new function silc_task_queue_wakeup to wakeup the
2801 scheduler by the specified task queue. Affected file
2802 lib/silcutil/silctask.[ch].
2804 * The silc_socket_host_lookup_start now wakes up the scheduler
2805 after adding the timeout task. Affected file is
2806 lib/silcutil/silcsockconn.c.
2808 * The silc_socket_host_lookup is synchronous now if the threads
2809 support is not compiled in. However, the callback is still
2810 called asyncronously through the scheduler, anyway. Affected
2811 file lib/silcutil/silcsockconn.c.
2813 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2815 * Added new function silc_socket_host_lookup to perform
2816 asynchronous IP and FQDN lookups for the socket connection.
2817 Affected files lib/silcutil/silcsockconn.[ch].
2819 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2821 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2822 that may or may not compile the mutex support in.
2824 Changed the silc_mutex_alloc interface. It allocates the
2825 mutex now to the sent pointer and returns TRUE or FALSE.
2827 Affected file lib/silcutil/silcmutex.h.
2829 * Wrote the SILC Task Queue interface to support multi-threads.
2830 Affected file lib/silcutil/silctask.[ch].
2832 * Wrote the SILC Scheduler to support multi-threads. Affected
2833 file lib/silcutil/silcschedule.c.
2835 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2837 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2838 in lib/silcutil/win32/.
2840 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2842 * Defined SILC Mutex API and SILC Thread API and implemented
2843 them for Unix. Affected files are
2844 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2845 lib/silcutil/unix/silcunixmutex.c and
2846 lib/silcutil/unix/silcunixthread.c.
2848 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2850 * Fixed the silc_server_remove_clients_by_server's channel
2851 key re-generation. The hash table handling was incorrect
2852 and would not work with many channels. Affected file is
2855 * Fixed some memory leaks around the server code.
2857 * Rewrote the silc_server_get_users_on_channel to support IPv6
2858 based Client ID's. Affected file silcd/server.c.
2860 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2861 specification. However, a separate document must be written
2862 to define the detailed signing procedure and the payload
2863 associated with the flag. Defined the flag to the
2864 lib/silccore/silcchannel.h as well.
2866 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2868 * Changed the dynamic tables to static size tables in the
2869 lib/silccrypt/silchmac.c.
2871 * Removed GCC dependencies from the code. A patch by cras.
2873 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2875 * Do not show the error "Error receiving packet bla bla"
2876 in server if it really was not an error (-2 means that reading
2877 is pending). Affected file silcd/server.c.
2879 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2881 * Fixed a possible crash in silc_server_remove_clients_by_server
2882 in silcd/server.c. Fixed there also some memory leaks.
2884 * Fixed the silc_idlist_replace_client_id. It could replace
2885 wrong key in the hash table. Affected file silcd/idlist.c.
2887 * Do not check whether there are global users on the channel
2888 if the channel->global_users is FALSE. Affected functions
2889 silc_server_remove_from_one_channel and
2890 silc_server_remove_from_channels in silcd/server.c. Also,
2891 do not check if the removed client is local as we can be
2892 sure that global client was not removed from the channel
2893 and checking for global users is not needed.
2895 * The silc_server_remove_clients_by_server now re-generates
2896 the channel keys correctly for those channels that had
2897 clients removed from them. Affected file silcd/server.c.
2899 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2901 * Found the reason of random crashes in the server. We weren't
2902 ignoring the SIGPIPE signal (which can be sent in write())
2903 and it crashed the server. Affected file silcd/silcd.c.
2905 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2907 * Assure that sock->user_data is not NULL in the function
2908 silc_server_packet_send in silcd/packet_send.c.
2910 * Disconnect the remote connection if it could not be added
2911 to any ID lists in the server. The affected file is
2914 * Check in silc_server_packet_send[_real/dest] that the
2915 socket is not disconnecting and ignore the data if it is.
2916 Affected file silcd/packet_send.c.
2918 * Define inline to __inline on native WIN32 compilation.
2919 Affected file includes/silcwin32.h.
2921 * Added some explicit type casts for inline code since MSVC
2922 require them. Affected files lib/silcutil/silcbuffer.h,
2923 lib/trq/silcdlist.h and lib/trq/silclist.h.
2925 * Print warning in log files from now on if the packet
2926 decryption fails. Affected file silcd/server.c.
2928 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2930 * Changed the `say' client operation's interface to accept
2931 new `type' argument to indicate the type of the message sent
2932 by the library. The application may filter the library's
2933 messages according the type. The affected file is the
2934 lib/silcclient/silcapi.h.
2936 * Added two new functions to lib/silcclient/silcapi.h:
2937 silc_client_del_client and silc_client_del_client_by_id.
2938 Affected file lib/silcclient/idlist.c.
2940 * Moved the clientincludes.h from includes/ to silc/ and
2941 serverincludes.h from includes/ to silcd/.
2943 * The modes for the CMODE and CUMODE are now passed as
2944 uint32 for application with COMMAND_REPLY. The affected
2945 file is lib/silcclient/command_reply.c.
2947 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2949 * /WHOIS without arguments shows client's own information.
2950 Affected file lib/silcclient/command.c.
2952 * Changed PING to not accept any arguments. The specs
2953 says that client can ping only the connected server so
2954 requiring an argument is not needed. Affected file is
2955 lib/silcclient/command.c.
2957 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2959 * Fixed a fatal bug in private message sending and reception
2960 encryption and decryption when using private message keys.
2961 The implementation was incorrect and did not follow the
2962 specification. It causd that some of the message were
2963 lost since it did not use the sending and receiving keys
2964 as the protocol suggests. This has been fixed and will cause
2965 incompatibilities with older clients when sending private
2966 message encrypted with private message keys. Affected files
2967 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2968 and various other in Irssi SILC Client.
2970 Added `responder' boolean argument to the functions
2971 silc_client_add_private_message_key[_ske] to indicate when
2972 the key is added as responder or initiator of the key
2975 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2977 * Removed the silc_ske_check_version function and created
2978 a SilcSKECheckVersion callback. Added also a function
2979 silc_ske_set_callbacks that is now used to set all SKE
2980 callbacks. The callback functions are not given to
2981 the SKE functions anymore, but this function is used to
2984 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2986 * Added `silc_version' argument to the silc_client_alloc
2987 to define the version of the application for the library.
2988 The library will use the version string to compare it
2989 against the remote host's (usually a server) version
2990 string. Affected file lib/silcclient/silcapi.h
2992 * Added the KE protocol context to Key Agreement context
2993 in client library so that we can abort the SKE if it
2994 is in process when we get timeout. Affected file is
2995 lib/silcclient/client_keyagr.c.
2997 * Do not resolve the client ID forever if it returns in the
2998 first time that such client does not exist. This was done
2999 for example with private message. Affected file is
3000 lib/silcclient/client_prvmsg.c.
3002 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3004 * Do not add regex.h for WIN32. The affected file
3005 includes/silcincludes.h.
3007 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3008 not work yet 100%. It generates the DLL's automatically
3009 when compiling with --with-win32 under cygwin.
3011 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3013 * lib/contrib/regex.c is not compiled on WIN32.
3015 * Added silc_net_get_socket_opt function to the
3016 lib/silcutil/silcnet.h.
3018 * Added includes/silcwin32.h for WIN32 specific includes
3021 * Do not use ptime structure or any of the posix process
3022 functions on WIN32 in lib/silccrypt/silrng.c.
3024 * Added silc_gettimeofday to provide generic function
3025 for struct timeval on all platforms. Added the function
3026 to lib/silcutil/silcutil.h.
3028 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3030 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3031 library as they clearly belong there. As a plus side we
3032 can make the actual socket connection routines platform
3035 Added also new generic function silc_socket_read and
3036 silc_socket_write (that used to be silc_packet_[read/write].
3037 The implementation of these are platform specific.
3039 * Added WIN32 specific routines of silc_socket_[read/write]
3040 to lib/silcutil/win32/silcwin32sockconn.c.
3042 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3044 * Added preliminary support for native WIN32 compilation under
3045 cygwin (using the -mno-cygwin option for GCC) to the
3046 ./configure.in.pre. The --with-win32 now prepares the
3047 compilation for native WIN32.
3049 * Rewrote the SILC Scheduler interface in the file
3050 lib/silcutil/silcschedule.h. The scheduler is now context
3051 based and does not have anymore any global static scheduler.
3052 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3053 and created lib/silcutil/win32 directory for WIN32 based
3056 * Added Unix specific network routines to the
3057 lib/silcutil/unix/silcunixnet.c and the old
3058 lib/silcutil/silcnet.c includes now only generic routines.
3060 Added WIN32 specific network routines to the
3061 lib/silcutil/win32/silcwin32net.c.
3063 * Added Unix specific utility functions from the
3064 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3066 * Added WIN32 SILC Scheduler to the file
3067 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3070 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3072 * Do not handle JOIN notify in the server if the target client
3073 is not registered (idata->registered == FALSE). The affected
3074 file is silcd/packet_receive.c.
3076 * Update the nickrec->founder in event_cumode in the Irssi SILC
3077 client. Affected file irssi/src/silc/core/silc-channels.c.
3079 * Fixed the CUMODE_CHANGE notify handling in the server when
3080 server and router are announcing their clients on channels.
3081 Now the mode changes are saved and notified correctly. The
3082 affected file is /silcd/packet_receive.c.
3084 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3085 They really did not replace the cache entry in the ID Cache.
3086 Now they do that. Affected file silcd/idlist.c.
3088 * Fixed the KICK notify handling in the Irssi SILC client to
3089 update the channel records so that the kicked client does not
3090 appear to be on the channel. The affected file is
3091 irssi/src/silc/core/silc-channels.c.
3093 * Always update the conn->current_channel when executing command
3094 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3096 * Fixed the KILL notify handling in Irssi SILC client to remove
3097 the killed client on all channels.
3099 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3101 * Fixed the silc_parse_command_line to remove extra spaces
3102 from the start and end of the arguments. Affected file is
3103 lib/silcutil/silcutil.c.
3105 * Cancel and free any active protocol in the function
3106 silc_server_close_connection. Affected file silcd/server.c.
3108 * Cancel and free any active protocol in the function
3109 silc_client_close_connction. Affected file is
3110 lib/silcclient/client.c.
3112 * Do not execute the KILL command for clients that are in
3113 history (ie. they are not in the network). Affected file is
3116 * Fixed KILL notify handling, client does not crash anymore.
3117 Affected file irssi/src/silc/core/silc-channels.c.
3119 * Reduced the default packet buffer size from 2048 to 1024 in
3120 lib/silccore/silcpacket.c.
3122 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3123 counter to the SKE context that is incresed when the SKE library
3124 performs async operation outside the library. If the outside
3125 process frees the SKE context and FREED status will be set
3126 and the library will detect after the sync operation that the
3127 libary is freed. The affected files are
3128 lib/silcske/silcske[_status].[ch].
3130 * Resolve the client entry information in the function
3131 silc_client_channel_message to assure that NULL pointer is not
3132 passed as client entry to the application. */
3134 * Fixed the task timeout calculation to assure that there is
3135 never negative timeouts. The affected file is
3136 lib/silcutil/silcschedule.c.
3138 * Fixed the channel user mode notification sending in server.
3139 It was sent point-to-point to the router (or to server by router)
3140 but it needs to be destined to a channel. The routines now
3141 supports sending the channel user mode notifys to the channels
3142 when announcing clients and channels. Affected files are
3143 silcd/server.c and silcd/packet_receive.c.
3145 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3146 It did not actually replace the old channel entry in the cache.
3147 Affected file lib/silcclient/client_notify.c.
3149 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3151 * Fixed a possible crash in silc_packet_send_prepare. It now
3152 assures always that there is enough space in the buffer and
3153 at the tail area of the buffer (for MAC).
3155 Fixed the inbound buffer reallocation in silc_packet_read.
3156 It was old code and did not handle the reallocation correctly.
3159 The affected file is lib/silccore/silcpacket.c.
3161 * Fixed buffer overflow in silc_parse_nickname in the file
3162 lib/silcutil/silcutil.c.
3164 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3166 * make install generates new server keys only if there is not
3169 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3171 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3172 Added check that if the NOREPLY is set then we will not send
3173 the away message. This avoids infinite loop of away messages
3174 if both clients are away. The affected file is
3175 lib/silcclient/client_prvmsg.c.
3177 * Fixed client crash if /NICK was given without arguments.
3178 Affected file lib/silcclient/command.c.
3180 * Server does not send the invite list in INVITE command back
3181 to the client if the list was not altered. Added this notion
3182 to the protocol spec as well. Affected file silcd/command.c.
3184 Fixed possible crash in INVITE command by checking the
3185 value of silc_server_get_client_route command.
3187 * Fixed the INVITE notify type handling. The arguments are now
3188 taken in correct order and client does not crash. The affected
3189 file is irssi/src/silc/core/silc-channels.c.
3191 Removed the "Inviting xxx to channel" message from the
3192 client library away and let the application handle it.
3193 Affected file lib/silcclient/command.c. Added that message
3194 to Irssi SILC client's message formats.
3196 * Fixed CMODE command crash in client. It now checks the
3197 amount of arguments correctly and does not crash. The affected
3198 file is lib/silcclient/command.c.
3200 * Do not create new channel automatically in silc_channels_join
3201 but check whether the channel by that name already exists.
3202 Affected file irssi/silc/core/silc-channels.c.
3204 * Do not send the SERVER_SIGNOFF to router if the disconnected
3205 entity was the router. Affected file silcd/server.c.
3207 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3208 SILC client as it was missing from there.
3210 Added the handling of the KICK notify to the Irssi SILC client
3211 as it was missing. Added "you have been kicked" message to
3212 Irssi SILC client's message modules formats.
3214 Added the handing of the KILL notify to the Irssi SILC client
3215 as it was missing. Added the kill message module formats
3218 The affected file is irssi/src/silc/core/silc-channels.c.
3220 * The router did not save the channel mode the server announced.
3221 Affected file silcd/packet_receive.c.
3223 * Fixed a possible crash in INFO command in server. If the
3224 server did not provide the server info it crashed. Affected
3225 file silcd/command.c.
3227 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3229 * Fixed the GETKEY command in the server to check also the
3230 global list. Otherwise the GETKEY would not work correctly
3231 in normal SILC server. Affected file silcd/command.c.
3233 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3235 * Fixed GETKEY crash, it crashed if the command did not succseed.
3237 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3239 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3240 is now real and not just an macro interface to GMP.
3242 Removed the entire GMP from the source tree and imported new
3243 NSS MPI library instead. Reason for removing GMP is that it is
3244 extremely large and compiles extremely slow. The NSS MPI
3245 is only a few files and compiles in less than 10 seconds.
3246 The speed is also about the same as GMP. The MPI is imported
3247 to lib/silcmath/mpi.
3249 If the system has GMP installed we will still use the GMP.
3250 If it is not then the NSS MPI will be compiled.
3252 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3254 * Merged a long nickname (127 characters long) crash bugfix from
3255 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3257 * Merged a freed memory reference bugfix from Irssi CVS tree.
3258 Affected file irssi/src/core/commands.c.
3260 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3262 * Added the server's public key sving and verification to the
3263 server when performing the SKE. This was missing and the
3264 remote server's (or router's) public key was accepted without
3265 checking whether we have it previously or trust it at all.
3266 Affected file silcd/protocol.c.
3268 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3270 * Check in the silc_server_timeout_remote if protocol is active
3271 and make sure that the protocol's final callback is called so
3272 that all memory if freed. Affected file silcd/server.c.
3274 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3276 * silc_server_whois_send_reply crashed the server if the nickname
3277 was 127 characters long. Affected file silcd/command.c.
3279 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3281 * Added sanity check to the silc_server_new_client. If the hostname
3282 is provided inside username then check that the provided hostname
3283 really is the same as the resolved one. If the hostname was not
3284 resolved then check it from the public key. Affected file is
3285 silcd/packet_receive.c.
3287 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3288 if the server disconnected us and the connection is not valid
3289 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3291 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3292 the library to the lib/silcutil/silcutil.[ch].
3294 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3296 * Close log file after open. Affected file
3297 lib/silcutil/silclog.c.
3299 * Check whether sock == NULL in silc_client_send_packet and return
3300 if it is. Affected file lib/silcclient/silcclient.c.
3302 * Check rec->entry == NULL in the Irssi SILC Client before
3303 sending the channel message. Affecte file is
3304 irssi/src/silc/core/silc-servers.c.
3306 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3308 * Merged a splitted window bugfix from Irssi CVS tree. The
3309 affected file is irssi/src/fe-text/textbuffer-view.c.
3311 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3312 It did not print nickname.
3314 * Improved the distributions system a bit.
3316 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3318 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3319 irssi/src/fe-text/gui-window.c.
3321 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3322 to in-active server. The affected file is
3323 irssi/src/silc/core/client_ops.c.
3325 * Resolve the client in USERS command reply if the entry does
3326 not have username resolved. The affected file is
3327 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3328 command to WHOIS command to really resolve stuff. The USERS
3329 is not used any more in any critical section so WHOIS can
3330 be used even though it might be slower than IDENTIFY.
3332 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3335 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3337 * Changed the protocol API a bit more consistent in the
3338 lib/silccore/silcprotocol.[ch].
3340 * Changed the following headers to ROBODoc format:
3342 lib/silccore/silcpayload.h
3343 lib/silccore/silcprotocol.h
3344 lib/silccore/silcsockconn.h
3346 All core library headers are now formatted.
3348 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3350 * Fixed a bug in Irssi SILC client; do not show that you are
3351 server/router operator if you really are not. Affected file is
3352 irssi/src/silc/core/client_ops.c.
3354 * Renamed silc_command_free_payload to silc_command_payload_free.
3355 Affected file lib/silccore/silccommand.h
3357 * Added silcmath.h to include the prototoypes of various routines
3358 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3361 * Changed the following headers to ROBODoc format:
3363 lib/silccore/silcchannel.h
3364 lib/silccore/silccommand.h
3365 lib/silccore/silcid.h
3366 lib/silccore/silcidcache.h
3367 lib/silccore/silcmode.h
3368 lib/silccore/silcnotify.h
3369 lib/silccore/silcpacket.h
3370 lib/silcmath/silcmath.h
3372 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3374 * Added checking to the server code not to start the server if
3375 ciphers and stuff are not configured properly. Affected files
3376 silcd/serverconfig.[h] and silcd/server.c.
3378 * Changed the layout of the header files of the public interfaces
3379 in the SILC libraries. The new layout supports ROBODoc
3380 documentation tool (and some others) so that it is easy to create
3381 a library reference manual. All the other headers and source
3382 code must still follow the CodingStyle document. Also source
3383 code must not include these ROBODoc stuffs, only the headers.
3384 Furthermore, all public interface headers must now be named
3385 by using `silc' prefix, example: silcapi.h, silccipher.h.
3386 Some files were renamed due to this. All the other headers
3387 must not be used as public interfaces. I will update the
3388 CodingStyle document later. Changed following headers, so far:
3390 lib/silcclient/silcapi.h
3391 lib/silccore/silcauth.h
3392 lib/silccore/silcprivate.h
3393 lib/silccrypt/silcdh.h
3395 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3399 * Removed silc_client_packet_send_flush from the client library
3400 as it is not needed. Affected file lib/silcclient/client.[ch].
3402 * Added printing of message of unresolved authentication method
3403 to the Irssi SILC client. Added it to the module formats.
3404 Removed the same message from the client library.
3406 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3408 * Added new distribution feature, DISTLABEL. Every distribution
3409 can define own preprocessor label that can be used in the
3410 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3411 file distributions, acconfig.h.pre and prepare.
3413 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Added Makefile.defines_int to include the actual definitions
3416 for Makefile.defines.in. Tested the new distribution system,
3417 created distributions and tested installation.
3419 * Added AWAY message printing to the Irssi SILC client. Added
3420 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3422 * Added SCONNECT command to call the SILC's CONNECT command.
3423 Cannot use CONNECT directly since Irssi uses that internally.
3424 Affected file irssi/src/silc/core/silc-servers.c.
3426 Added ACTION local command. It is same as ME command but takes
3427 the channel as mandatory argument.
3429 Rewrote some of the Irssi's help files to suite for SILC
3432 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3434 * Added Makefile.defines[.in] that should for now on be included
3435 in all Makefile.am file in the source tree. That file includes
3436 all common compilation definitions for SILC source tree.
3438 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3440 * Minor changes to the ./prepare script to change the package
3441 name according the distribution name to the configure.in.
3443 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3445 * Created new distribution system. Added file `distributions'
3446 that defines all the distributions that can be created out of
3447 the SILC source tree. The ./prepare script now reads that
3448 file to determine how to prepare the distributions. The
3449 first argument to the ./prepare is the name of the distribution
3450 and second is the version of the distribution. If given
3451 without arguments it creates the default (toolkit) distribution
3452 with the default version (defined in ./prepare).
3454 All Makefile.am files that are subject to the distributions
3455 are now named as Makefile.am.pre. These are ./Makefile.am
3456 and lib/Makefile.am. Others may be changed later.
3458 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3460 * Added invite list, ban list, some key management and connection
3461 error message printing to module formats in the Irssi SILC client.
3463 * Added new silc_client_set_away_message to set the away message
3464 that is back to the person who sent private message. The
3465 affected file lib/silcclient/silcapi.h and the
3466 lib/silcclient/client_prvmsg.c.
3468 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Fixed the private message sending in the Irssi SILC client,
3471 added local command KEY to the Irssi SILC client.
3473 Added key management and key agreement message formats to the
3474 irssi/src/fe-common/silc/module-formats.[ch].
3476 Added USERS (alias WHO) printing, server/router operator
3477 indication and LIST command printing to the module formats.
3479 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3481 * Fixed channel joining notify handling, cumode notify handling
3482 from Irssi SILC client.
3484 * Added SILC specific module-formats to the Irssi SILC client so
3485 that SILC specific message hilighting, colors etc is possible.
3486 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3488 Added channel mode, channel user mode, actions, notices,
3489 whois and whowas printing to the the module-formats.c.
3491 * Fixed a bug in channel deletion in the server. The channel
3492 is not left to the cache even if the channel founder auth mode
3493 is set when there are no users anymore on the channel. Affected
3494 file silcd/server.c.
3496 * The silc_net_localhost now resolves the entire hostname including
3497 the domain name. Affected file lib/silcutil/silcnet.c.
3499 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3501 * Changed the ask_passphrase client operation to be ascynchronous.
3502 It has now a completion callback and a context that the
3503 application must call after it has got the passphrase from
3504 the user. Affected files lib/silcclient/silcapi.h,
3505 lib/silcclient/protocol.c, lib/silcclient/command.c and
3508 Added SilcAskPassphrase callback that the application calls
3509 to deliver the passphrase to the library.
3511 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3512 The public key verification and especially a certificate
3513 verification is asynchronous procedure.
3515 Added new SILC_SKE_STATUS_PENDING status to indicate the
3516 request is pending and a callback will be called to finalize
3519 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3520 indicate that remote end did not send its public key (or
3521 certificate), even though we require it. Added check for this
3522 condition in the SKE. This was a security bug, now fixed.
3524 Defined new SilcSKEVerifyCbCompletion callback that is called
3525 when the verification process is completed.
3527 The affected files lib/silcske/silcske_status.h and
3528 lib/silcske/silcske.[ch].
3530 * Changed the verify_public_key client operation to be async
3531 as well. Defined SilcVerifyPublicKey callback that is used to
3532 indicate the success of the public key verification process.
3534 Changed the server and client to use the new async client
3537 * Changed the Irssi SILC client's internal scheduler to be called
3538 twice as many times as it used to be. As a result the client
3539 should be a bit faster now. Affected file is
3540 irssi/src/silc/core/silc-core.c.
3542 * Added support to Irssi SILC client of asynchronous public key
3543 verification and passphrase inquiry. Affected file is
3544 irssi/src/silc/core/silc-core.c.
3546 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3548 * Do not say "You have left channel %s" in client library.
3549 Moved it to the application. Affected files are
3550 lib/silcclient/command.c and silc/client_ops.c.
3552 * Fixed silc_client_get_clients. Command context was not
3553 duplicated and was freed memory in the callback. Affected
3554 file lib/silcclient/idlist.c.
3556 * Do not say "you are now talking..." on JOIN command in the
3557 client library. The appliation must handle it.
3559 * Do not say ".. changed topic to" in command reply in the
3560 client libary. The application must handle it.
3562 * Fixed TOPIC command sending in the client library.
3564 * Fixed a memory leak in silc_client_command_free in the file
3565 lib/silcclient/command.c.
3567 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3569 * Imported a modified version of Irssi client to the source tree.
3570 The Irssi will be used to create a new client called
3571 Irssi SILC. Imported to irssi/.
3573 Added silc_core_init_finish function to the Irssi. Affected
3574 file irssi/configure.in.
3576 A lot changes in the Makefile.ams around the irssi tree.
3578 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3580 * Do not rehash if the new size is same as the old size of the
3581 hash table, in the silc_hash_table_rehash*. The affected file
3582 lib/silcutil/silchashtable.c.
3584 * Replaced hash_table_del_by_context calls from the server
3585 (when channel->user_list and client->channels) to the
3586 hash_table_del as it is sufficient and faster.
3588 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3590 * Added silc_hash_table_list, silc_hash_table_get and the
3591 SilcHashTableList structure to provide an alternative way to
3592 traverse the hash table. The affected files are
3593 lib/silcutil/silchashtable.[ch].
3595 * Changed the server's idlist routines to use the hash table
3596 routines to optimize the code.
3598 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3600 * Replaced the client entry's `channel' list and channel entry's
3601 `user_list' list to hash tables for optimized lookup. Changed
3602 the code to use the hash table interface around the code.
3603 Affected file lib/silcd/idlist.[ch].
3605 * Added `auto_rehash' boolean argument to the function
3606 silc_hash_table_alloc to indicate whether the hash table should
3607 auto-rehash when it thinks is appropriate time. It will
3608 increase the hash table size if the there is twice as much
3609 entries in the table than the size of the table, and will
3610 decrease the size if there are twice as less entries than
3611 the size of the table.
3613 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3615 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3617 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3619 * silc_idcache_purge_by_context deletes the entry now by context
3620 as it is supposed to do. Affected file lib/silccore/idcache.c.
3622 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3623 client is not anymore valid (WHOWAS givens the info) and not
3624 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3626 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3628 * Removed the `data' and `data_len' arguments from the ID Cache
3629 interfaces and added `name' argument. ID Cache does not handle
3630 anymore the binary data only a names associated with given ID.
3632 * When hashing a Client ID with silc_hash_id the entire ID is
3633 not hashed anymore, instead only the hash of the Client ID is
3634 hashed. This way we can access the Client ID from the cache
3635 with Client ID but with the hash of the ID (which is a hash of
3636 the nickname) as well without any difference in performance.
3638 Added also silc_idcache_find_by_id_one_ext to do one on one
3639 searching when we have the actual ID. Added also function
3640 silc_hash_client_id_compare. The affected files are
3641 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3643 * When hashing the name associated with a ID it is always done
3644 in lowercase. This way we can access the cache without worrying
3645 about case-sensitivity, even though, for example nicknames are
3648 * Fixed a bug in server with channel message sending. It put
3649 wrong ID type as destination ID. The affected file
3650 silcd/packet_send.c.
3652 * silc_idcache_del_by_context now deletes from all hash tables
3653 by context. Affected file lib/silccore/idcache.c.
3655 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3657 * Changed the client library to use the new ID Cache interface.
3658 Changes around the source tree.
3660 * Added silc_hash_table_rehash_ext to rehash with specific
3661 hash function. Affected file lib/silcutil/silchashtable.[ch].
3663 * Added silc_hash_string_compare to compare two strings in the
3664 hash table. Affected file lib/silcutil/silcutil.[ch].
3666 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3668 * Added new function silc_idcache_del_by_context into the
3669 lib/silccore/idcache.[ch].
3671 * Changed the server's ID list routines to use the new ID Cache
3672 interface. Changes around the source tree.
3674 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3676 * Added silc_hash_table_del[_by_context]_ext functions in to the
3677 lib/silcutil/silchashtable.[ch].
3679 Removed silc_hash_table_find_all* routines and added new
3680 silc_hash_table_find_foreach to replace them.
3682 Added silc_hash_table_replace_ext function as extended
3683 replacing function. Separated the simple hash table interface
3684 from the extended hash table interface in the file
3685 lib/silcutil/silchashtable.h.
3687 * Fixed minor bugs and changed it to use some of the new
3688 hash table functions in lib/silccore/idcache.c
3690 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3692 * Added new function silc_hash_table_find_all to return all keys
3693 in the hash table by the specified key. As the hash table is
3694 collision resistant it also makes it possible to have several
3695 duplicate keys in the hash table. This function may be used to
3696 find all of the keys from the hash.
3698 Added user_context arguments to the SilcHashFunction,
3699 SilcHashCompare and SilcHashDestructor to deliver user specified
3702 Added new fuctions silc_hash_table_find[_all]_ext to do
3703 extended lookup with specified hash and compare functions and
3704 specified user contexts.
3706 Added new function silc_hash_table_add_ext to add the key
3707 with specified hash function and user context.
3709 Added new function silc_hash_table_foreach to traverse all
3710 entrys in the hash table. Added SilcHashForeach callback
3713 Added new function silc_hash_table_del_by_context to delete
3714 the entry only if the context associated with the key matches.
3716 Affected files are lib/silcutil/silchashtable.[ch].
3718 * Removed silc_hash_[server/client/channel]_id and added just
3719 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3720 silc_hash_id_compare to compare two ID's using as the hash table
3721 comparison function. Added also silc_hash_data to hash
3722 binary data and silc_hash_data_compare to compare it.
3724 * Removed silc_idlist_find_client_by_hash as it is not needed
3725 anymore. Affected file silcd/idlist.[ch].
3727 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3728 to use internally the SilcHashTable. The new ID Cache is a lot
3729 faster than the old one. Some of the ID Cache interface was also
3730 rewritten and obsolete and stupid functions were removed.
3732 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3734 * Added entry_count field to the SilcHashTable to keep the number
3735 of the entries in the table. Implemented the function
3736 silc_hash_table_rehash. Added new function
3737 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3739 Fixed a minor bug in silc_hash_table_free.
3741 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3742 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3743 into the lib/silcutil/silcutil.[ch].
3745 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3747 * Implemented a collision resistant hash table into the
3748 lib/silcutil/silchashtable[ch]. See the header and the source
3749 for the SilcHashTable API.
3751 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Merged dotconf version 1.0.2 into lib/dotconf.
3755 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3757 * Do not compile anything in lib/silcsim/* if the SIM support
3758 is not enabled. The tree should now compile without problems
3761 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Compiled the SILC under cygwin. Compiled and tested briefly
3764 without problems. More tests needed. The SIMs didn't compile
3767 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3769 * Fixed possible crash in silc_get_username in the
3770 lib/silcutil/silcutil.c.
3772 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3774 * Fixed a va_arg in silc/client_ops.c.
3776 * Oops, RC5 routines were named AES and caused some problems
3777 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3779 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3781 * Added new SilcIDIP structure into the lib/silccore/id.h and
3782 replaced the old `ip' fields from all SILC ID's to that type.
3783 This is a step towards IPv6 support.
3785 The silc_id_get_len takes now the ID as an extra argument.
3786 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3787 both IPv4 and IPv6 based ID's.
3789 The affected files are lib/silccore/id.[ch] and other files
3790 around the tree using these routines.
3792 * Removed the ID length arguments in server from various
3793 silc_server_send_notify_* routines -> they are not needed
3796 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3798 * Fixed memory leak in silc_encode_pem_file in the file
3799 lib/silcutil/silcutil.c.
3801 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3803 * Check minor version as well in the SKE. Affected files are
3804 silcd/protocol.c and lib/silcclient/protocol.c.
3806 * Added --identifier option to the server so that an identifier
3807 can be when creating the public key for the server. Affected
3808 file is silcd/silcd.c.
3810 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3811 lib/silccrypt/silcpkcs.c.
3813 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Register default ciphers and stuff when using -C option with
3816 the server. Affected file sildc/silcd.c.
3818 * Put back the servers public key filename format, it is better
3819 than the new one. For now, the client keys are saved with the
3820 new filename format. The affected file silc/client_ops.c.
3822 * Implemented the Cipher API for the rest of the ciphers that
3823 did not implement it or implemented it the wrong way.
3825 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3827 * Register default ciphers and stuff when using the -S option
3828 in the client. Affected file silc/silc.c. Same also when
3829 creating new key pair with -C option.
3831 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Fixed the silc_verify_public_key client operation function to
3834 save the public keys differently. The fingerprint is now
3835 used as filename and not the hostname. This way also the
3836 client keys are saved uniquely and not with hostnames. The
3837 affected file is silc/client_ops.c.
3839 * Trimmed the silc_hash_fingerprint function to remove extra
3840 whitespaces from the end of the fingerprint. The affected
3841 file is lib/silccrypt/silchash.c.
3845 * Added silc_cipher_register_default function to register all
3846 default ciphers. It can be used when configuration files
3847 does not exist and the application does not want any specific
3848 ciphers in any specific order.
3850 The SilcDList is now used as silc_cipher_list dynamically
3851 allocated cipher list. Removed the static list all together
3852 and now all ciphers must be allocated to the dynamic list.
3853 The silc_cipher_alloc routine was changed to check only the
3856 All silc_cipher_* routines that used to return int returns
3859 The affected files lib/silccrypt/silccrypt.[ch].
3861 * The same thing was done to silc_hash_* as for silc_cipher_*
3862 routines. Affected files lib/silccrypt/silchash.[ch].
3864 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3865 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3866 Added also silc_pkcs_[un]register[_default] functions.
3867 Removed the data_context from the PKCS API.
3869 * Added silc_hmac_register_default function to register default
3870 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3871 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3872 to unregister all hmacs at once.
3874 * Register the default ciphers, hash functions, PKCSs and HMACs
3875 if client's configuration file does not exist. The affected
3878 * The client did not load the hash functions from the SIM
3879 modules at all. Added support for this. Affected file is
3880 silc/clientconfig.c.
3882 * When decoding public key with silc_pkcs_public_key_decode, check
3883 the supported algorithm only if PKCS are registered. Affected
3884 file lib/silccrypt/silcpkcs.c. The same was done with the
3885 silc_pkcs_private_key_decode.
3887 * Fixed the SILC List routines to keep the list always in order.
3888 It used to change the list's order when traversing the list but
3889 not it preserves the order. Affected file lib/trq/silclist.h.
3891 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Added the client library to use the SilcSocketConnection's
3894 reference counter (by silc_socket_dup) to prevent the bug that
3895 the socket object may be freed underneath async operation.
3897 * The name resolv library checking fixes in the configure.in.pre.
3900 * Created new version of the protocol drafts for future
3901 development. The -03 drafts are the ones that will be changed
3902 in the trunk now and the -02 will remain as they are.
3904 * Send list of CUMODE notifys to the router when announcing
3905 the channel users to the router. Affected file silcd/server.c.
3906 If the router receiving channel founder CUMODE for a channel
3907 that already has channel founder it will send CUMODE notify
3908 to the sender to remove the channel founder rights from the
3909 announced client. Affected file silcd/packet_receive.c.
3911 * The CUMODE notify may now use Server ID as well as the entity
3912 who changes the mode. Updated protocool specs.
3914 * Updated INSTALL and README files.
3916 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3918 * New web pages in the http://silc.pspt.fi. The pages was
3923 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3925 * Implemented the [DenyConnectin] config section in the server.
3926 Added silc_server_config_denied_conn to check whether incoming
3927 connection is denied. Affected file silcd/serverconfig.[ch].
3929 * Do not check the ports when checking the incoming configuration
3930 data if the port is 0, meaning any. Affected file is
3931 silcd/serverconfig.c.
3933 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3935 * Fixed buffer overflow in silc_string_compare in the file
3936 lib/silcutil/silcutil.c.
3938 * Fixed double free in silc_server_command_leave in the file
3941 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3943 * Fixed the version checking in the server. Affected file is
3946 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Fixed the configuration data fetching when accepting new
3949 connections in the server. Affected file silcd/server.c.
3951 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3953 * Added `sender_entry' argument to the function
3954 silc_server_packet_relay_to_channel so that we can check
3955 whether some destination actually belongs to the same route
3956 the sender belongs (ie, we must not resend the packet to the
3957 sender). Affected file silcd/packet_send.[ch].
3959 * Added `servername' field to the SilcClientEntry in the server
3960 to hold the name of the server where client is from. Affected
3961 file is silcd/idlist.h.
3963 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3965 * Moved the channel message encrypting in the router betwen
3966 router connections from silc_server_channel_message to the
3967 silc_server_packet_relay_to_channel since we want to check
3968 whether we have anybody channel before encrypting anything.
3969 Affected files silcd/packet_[receive/send].c.
3971 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3973 * Fixed the [AdminConnection] server config section to support
3974 multiple entries. Affected file silcd/serverconfig.c.
3976 * Added support into the server to check the validity of the
3977 incoming connection before executing any KE or authentication
3980 * The connection configuration is now saved to the KE and
3981 connection auth protocol contexts and not fetched anymore in
3982 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3984 * The local hosts listenning address and port is also resolved
3985 now when starting the server. We want to have the socket object
3986 to include the real address and port for the listener. Added
3987 new function silc_net_check_local_by_sock into the files
3988 lib/silcutil/silcnet.[ch].
3990 * Fixed a broadcast bug in server -> do not broadcast if we
3993 * Fixed a routing bug. Do not route broadcast packets ever.
3994 Broadcast packets must be processed always and not routed since
3995 they may be destined to some other host than yourself and thus
3996 would get routed without no good reason. Affected file is
3999 * Added function silc_server_config_is_primary_route to check
4000 whether primary router connection has been configured (a router
4001 configuration that we are initiating). If there is not, we
4002 will assume that there is only two routers in the SILC network
4003 and we will use the incoming router connection as our primary
4004 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4006 * Changed the order of the broadcasting. Broadcast _after_ the
4007 packet has been processed not before. Affected file is
4010 * Fixed a [ClientConnection] parsing bug. The port was never
4011 parsed correctly thus resulting to port 0. Affected file
4012 silcd/serverconfig.c.
4014 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4015 argument and did not set the broadcast packet flag. Affected
4016 file silcd/packet_send.c. Fixed same bug in the function
4017 silc_server_send_notify as well.
4019 * If we receive NEW_ID packet for our own ID in the server, ignore
4022 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4026 * Removed the nickname from the Private Message Payload.
4027 Updated the code and the protocol specs.
4029 * Updated protocol specs for submitting to the IETF.
4031 * Tweaked the Random Number Generator a bit. Affected file
4032 lib/silccrypt/silcrng.c. Exported a new function
4033 silc_rng_[global]_add_noise which can be used to add more
4036 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4038 * Do not parse packets with different timeout when protocol
4039 is active -> may cause problem with rekey. Affected file
4042 * When server receives signoff notify it must not create
4043 new channel key if the client is on any channels since the
4044 sender of the signoff notify will create it.
4046 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Added printing of error messages during SKE protocol from the
4049 failure packet sent by server during SKE. Affected file
4052 * Removed the client's failure_callback handling with timeout
4053 and handle it immediately when received.
4055 * The SKE library returned wrong type in SUCCESS and FAILURE
4056 packets. They must be 32 bit MSB not 16 bit MSB.
4058 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4060 * Ok, rewrote the logic of the re-key and now it seems to work.
4061 I tested it on high traffic with frequent re-keys without
4062 problems. Added hmac_receive (and renamed hmac to hmac_send)
4063 in SilcClientConnection in lib/silcclient/client.h and
4064 in SilcIDListData in silcd/idlist.h. Also, removed the
4065 SilcPacketParserContext's cipher and hmac fields as they are
4066 not needed anymore and actually caused some problems when
4067 the ciphers and hmac's changed underneath the packet parser.
4069 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4071 * If re-key protocol is active then process the incoming packets
4072 synchronously since we must assure that icoming packets encrypted
4073 with the old key is processed before the new keys is set to
4074 use. This is true other packets than for REKEY packets.
4075 Affected file silcd/server.c. The same was done to client library
4076 as well, affected file lib/silcclient/client.c.
4078 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4080 * Fixed bug in client and server to accept the force send if
4081 the packet is send from silc_[server/client]_packet_process
4082 function. Otherwise the packets are never delivered, oops.
4084 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4086 * Disable force sending of packets when REKEY protocol is active.
4087 We must assure that no packet is sent directly when rekey is
4088 performed. All packets must be sent through packet queue.
4089 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4090 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4091 function is silc_[server/client]_packet_send_real to check
4094 * Replaced the SIM paths from example config files to
4095 /usr/local/modules. Also, make install creates now
4096 /usr/local/silc/logs directory to hold all the SILC server
4099 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4101 * Made the configure.in.pre work on Solaris. Patch by salo.

4108 * Fixed the make install.
4110 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4112 * When MAC computation fails the silc_packet_decrypt returned 0
4113 even though it was supposed to return -1. Fixed this. The
4114 affected file is lib/silccore/silcpacket.c.
4116 * Do not replace the config files in /etc/silc (in make install)
4117 if they already exist. Affected file ./Makefile.am.
4119 * Do not send re-key packets immediately but through packet queue.
4120 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4122 * Changed silc_net_check_host_by_sock to return FALSE if the
4123 IP/DNS could not be resolved. Though, it returns the IP address
4124 now even if it could not resolve it (but returns also FALSE).
4125 Affected file lib/silcutil/silcnet.[ch].
4127 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4129 * Added silc_pkcs_decode_identifier to decode the public key's
4130 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4131 Added also silc_pkcs_free_identifier. Added also new context
4132 SilcPublicKeyIdentifier.
4134 * Added -S option to the silc client. It is used to dump the
4135 contents of the specified public key file.
4137 * Changed the PKCS api to return the public key length when
4138 setting the public key.
4140 * Fixed a fatal bug in the public and private key file loading.
4141 Affected file lib/silccrypt/silcpkcs.c.
4143 * Execute the packet parsing for client with zero (0) timeout
4144 if the protocol is active. Affected file silcd/server.c.
4146 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4148 * Made the key generation options to the silcd program. Added
4149 -C option, equivalent to client's option.
4151 * Added new [ServerKeys] config section to the server. It
4152 configures the server's public and private key.
4154 * Defined generic Public Key Payload into the protocol
4155 specification to send specific type of public keys and
4158 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4159 public key or certificate.
4161 * Implemented the GETKEY command to the server and to the
4162 client library and on user interface.
4164 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * Made preliminary `make install' work.

4195 SilcClientConnection structure; not needed. Affected file is
4196 lib/silcclient/client.h.
4200 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4202 * Do not ask whether user wants to use the negotiated private key
4203 for private messages, just use it. Affected file is
4204 silc/local_command.c.
4206 * Added `send_enc_key' and `enc_key_len' fields to the
4207 SilcIDListData structure since they are needed in the re-key

4222 the PFS is to be performed in the re-key. Affected file is
4225 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4227 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4228 int64 of at least the xintXX size. If void * is less that 4
4229 bytes uint32 * will be used. Defined bool as boolean.
4231 * Changed _ALL_ unsigned long and unsigned int to uint32,
4232 unsgined short to uint16 in the source tree.
4234 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4235 not handle clients that has entry->data.registered == FALSE.
4236 They are not in the network anymore. Affected file is
4239 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4241 * Implemented the sending of the SERVER_SIGNOFF notify in the
4242 server. Affected file is silcd/server.c.
4244 * Added silc_server_send_notify_args into silcd/packet_send.[ch].

4254 application. Affected file silc/client_ops.c.
4256 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4257 if the deleting was successful. Affected file silcd/idlist.[ch].
4259 * Added support for public key authentication in the connection
4260 authentication protocol in the client library. Affected file
4261 lib/silcclient/protocol.c.
4263 * Changed the server's silc_idlist_get_clients_by_* interface
4264 to support already allocated array so that new entries may be
4265 added to pre-allocated array. Affected file silcd/idlist.[ch].
4266 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4267 and command replies.
4269 * All command reply functions in the server now calls the
4270 pending command callback even if error occured. This way the
4271 error will be delivered to the client as well. Affected files
4272 silcd/command.c and silcd/command_reply.c.
4274 * Fixed INFO command to return local server's info if no server
4275 was provided. Affected file lib/silcclient/command.c.
4277 * Removed RESTART command for good. Updated the code and the
4280 * Rewrote parts of the task system. It is a bit simpler now.
4281 Removed unsued task priorities. The affected files are
4282 lib/silcutil/silctask.[ch].
4284 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4286 * Moved the USERS printing from the library to the application.
4287 Affected files lib/silcclient/command.c and silc/client_ops.c.
4289 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4293 * Added channel key re-key support. The re-key is perfomed
4294 only by the router and is done once in an hour. Added `rekey'
4295 field to the SilcChannelEntry in the server. Affected files
4296 silcd/server.c and silcd/idlist.h.
4298 * Added silc_task_unregister_by_context into the file
4299 lib/silcutil/silctask.[ch].
4301 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4303 * Added SILC_UMODE_GONE mode to indicate when the client is not
4304 present in the SILC network. Added also support to the local
4305 command AWAY that will set this mode. Added support of showing
4306 "xxx is gone" in WHOIS command. The USERS command shows the
4307 gone status as well.
4309 * Fixed setting server and router operator privileges in the
4310 server's UMODE command. Affected file silcd/command.c.
4312 * Merged the SKE KE1 and KE2 payloads into one payload. The
4313 new KE payload is equivalent to the old KE2 payload.
4315 Cleaned up the SKE Start Payload parsing. It now uses the
4316 simple buffer unformatting to do the parsing. A lot faster
4319 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4320 to the SKE that is used to indicate whether both of the SKE
4321 parties should perform authentication. By default only the
4322 responder performs authentication. By setting this flag also
4323 the initiator must do authentication. By default it is unset
4324 since in normal SKE case, client to server connection, only
4325 the responder should do authentication. When doing SKE between
4326 two clients both should perform authentication. Updated the
4327 code and the protocol specs.
4329 * A little fix to IDENTIFY command in the server. Search the
4330 client first by hash not nickname. Affected file is
4333 * Fixed the silc_client_close_connection to support closing
4334 the client to client connections wihtout deleting too much
4335 data. Affected file lib/silcclient/client.c.
4337 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4338 are received if protocol used to be active but is not anymore
4339 the application would crash due to NULL pointer dereference.
4340 Affected files silcd/server.c and lib/silcclient/client.c.
4342 * Added `hash' field to the SilcClientConnection to include
4343 the hash function negotiated in the SKE protocol.
4345 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4346 to set the channel founder authentication data. A client can
4347 claim the founder rights later by providing the authentication
4348 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4349 This way the channel founder can regain the channel founder
4350 privileges even it is left the channel. This works only on
4351 local server and the client must be connected to the same
4352 server to be able to regain the founder rights. Updated the
4353 protocol specs accordingly.
4355 Added support to the CMODE command in the client to set the
4356 founder auth data. Read the README to see how to set it.
4358 Added support to the CUMODE command to claim the founder
4359 rights. Read the README to see how to do it.
4361 Added support for the founder authentication to the Channel
4362 Entry in the server. Affected file silcd/idlist.h.
4364 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4365 server's CMODE command. Affected file silcd/command.c.
4367 * Added the following new functions into lib/silccore/silcauth.[ch]:
4368 silc_auth_get_method and silc_auth_get_data.
4370 * The server now saves the remote hosts public key to the
4371 SilcIDListData pointer. Affected file silcd/protocol.c.
4373 * The normal server now does not remove the channel entry from
4374 the cache if the founder authentication data is set. It used
4375 to remove it if the founder was the last one on the channel on
4376 the server and left the channel. The auth data is saved and
4377 if the channel is re-joined later the old entry is used with
4378 the old auth data. Affected files silcd/command_reply.c and
4381 * Removed the `pkcs' field from the SilcIDListData structure
4382 in the server; it is not used. Affected file silcd/idlist.h.
4384 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4386 * Fixed packet processing on slow links. Partial packets were
4387 never re-processed because the incoming data buffer was cleared
4388 by the application. Application must not directly clear the
4389 sock->inbuf, the packet processing routines handle it. Fixed
4390 this in client library and in server.
4392 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4394 * Fixed the WHOIS and IDENTIFY send reply function to really
4395 check whether to send list or just one entry. Affected file
4398 * Cleaned up the LEAVE command's channel key distribution. The
4399 affected file silcd/command.c.
4401 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4402 can enforce the channel mode as well. In that case the ID
4403 includes the ID of the server. The code now enforces the
4404 mode change if the router have different mode than the server.
4406 * The notify client operation with CMODE_CHANGE notify can now
4407 return NULL client_entry pointer if the CMODE was not changed
4408 by client. Application must check for this.
4410 * Added <Server ID> argument to INFO command to support server
4411 info fetching by Server ID.
4413 * Added silc_server_announce_get_channel_users to get assembled
4414 packets of channel users of the specified channel. Affected
4415 file silcd/server.[ch].
4417 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4418 was freed underneath the ID Cache.
4420 * Re-announce clients when the server received CHANNEL_CHANGE
4421 notify from the router. Affected file silcd/packet_send.c.
4423 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4425 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4426 crashed since it did not handle the fact that there is no cipher
4427 called "3" and didn't check the error condition. Now fixed.
4429 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4430 flag. It can be used to send message requests.
4432 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4434 * Implemented the RESTART command in the client.
4436 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4437 notice type messages. Added notice printing to the user
4440 * The channel keys are not re-generated if the channel's mode
4441 is PRIVKEY, ie private key on the channel exists. Affected
4442 files silcd/server.c and silcd/command.c.
4444 * Fixed a little bug in channel message delivery when channel
4445 private keys are set in the server. Affected file is
4446 silcd/packet_send.c.
4448 * Changed the setting on channel->on_channel = TRUE from the
4449 silc_client_save_channel_key to the JOIN command reply. The
4450 key payload is not received if the private channel key is set.
4451 Affected file lib/silcclient/command_reply.c and the
4452 lib/silcclient/client_channel.c.
4454 * When the CMODE_CHANGE notify is sent and the channel private
4455 key mode is removed the channel key must be re-generated in
4456 other cells as well. Added this support for the router in the
4457 silcd/packet_receive.c.
4459 * Added new local command NOTICE to send notice message on
4460 channel. Affected file silc/local_command.[ch].
4462 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * Added new local command ME to the client. It is used to send
4465 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4466 some action. Affected file silc/local_command.[ch].
4468 * Changed channel_message and private_message client operations
4469 to deliver the message flags to the application. Added also
4470 the `flags' arguments to the silc_client_send_channel_message
4471 and silc_client_send_private_message functions. Affected file
4474 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4476 * Redefined the Private Message Payload to support private message
4477 keys and to support the new private message flags. Updated
4478 the protocol specs. Flags makes it possible to have for example
4479 CTCP style messages.
4481 * Added new type SilcPrivateMessagePayload and defined an API
4482 for it in the lib/silcclient/silcprivate.[ch].
4484 * Tested private message private keys successfully. Tested the
4485 private message key set, unset and list commands with the new
4488 * Redefined the Channel Message Payload to include the channel
4489 message flags (equal with private message flags) to support
4490 for example CTCP style messages.
4492 * Defined some of the message (for channel and private message)
4493 flags. Updated the protocol specs and added the flags to the
4494 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4496 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * Added SilcKeyAgreementStatus type to the key agreement routines
4499 to indicate the current status and error if one occured.
4500 The status types are defined in the lib/silcclient/silcapi.h.
4502 * Added new local command KEY that is used to set and unset private
4503 keys for channels, set and unset private keys for private messages
4504 with remote clients and to send key agreement requests and
4505 negotiate the key agreement protocol with remote client. The
4506 key agreement is supported only to negotiate private message keys,
4507 it currently cannot be used to negotiate private keys for channels,
4508 as it is not convenient for that purpose.
4510 * Fixed a minor pending callback setting bug in the function
4511 silc_client_get_client_by_id_resolve, now the function works.
4512 Affected file lib/silcclient/idlist.c.
4514 * Added function silc_net_get_local_port to get local bound
4515 port by socket. Added to lib/silcutil/silcnet.[ch].
4517 * Added `sockets' and `sockets_count' fields to the SilcClient
4518 object. They hold the sockets of the listenning sockets in
4519 the client. Listenning sockets may be for example the key
4520 agreement server. Affected file lib/silcclient/client.[ch].
4521 Added functions the silc_client_add_socket and the
4522 silc_client_del_socket. They are exported to the application
4525 * Added ~./silc/clientkeys to support other client's public keys.
4527 * Renamed verify_server_key client operation to verify_public_key
4528 and added one argument to indicate the type of the connection
4529 (server, client etc.).
4531 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4533 * Added silc_server_connection_auth_request to handle the
4534 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4535 silcd/packet_receive.[ch].
4537 * Added silc_server_send_connection_auth_request into the
4538 silcd/packet_send.c to send the connection auth request packet.
4540 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4543 * Fixed the public key authentication in responder side in the
4544 server. The `auth_data' pointer includes the SilcPublicKey
4545 not the path to the public key. Affected file silcd/protocol.c.
4547 * Implemented the public key authentication in the initiator side
4548 in the server. Affected file silcd/protocol.c.
4550 * Removed the [RedirectClient] config section from the server
4551 configuration. Is not needed and I don't want to implement it.
4553 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4555 * Cleaned up the CMODE command in the server. It now works
4556 correctly and supports all the modes defined in the protocol.
4557 Affected file is silcd/command.c.
4559 * Added `hmac_name' field to the SilcChannelEntry in the server
4560 to hold the default HMAC of the channel. It can be set when
4561 creating the channel (with JOIN command). Affected files
4564 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4565 type to indicate the change of the current cipher and hmac
4566 on the channel. Client can safely ignore the <cipher> argument
4567 (if it chooses to do so) since the CHANNEL_KEY packet will
4568 force the channel key change anyway. The <hmac> argument is
4569 important since the client is responsible of setting the new
4570 HMAC and the hmac key into use.
4572 * Fixed the CMODE command in the client library as well.
4574 * Tested CMODE command in router environment successfully.
4576 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4578 * Show the version of the remote client (or server) when connecting
4579 to the server. It is logged to the log file. Affected file
4580 is silcd/protocol.c.
4582 * Fixed the KILLED notify handling in the client library. The
4583 client must be removed from all channels when receiving the
4586 Also, do not remove the client entry when giving the KILL
4587 command but when the KILLED notify is received.
4589 * Removed silc_idlist_find_client_by_nickname from the server.
4590 Not needed anymore. Affected files silcd/idlist.[ch].
4592 * Implemented the CHANNEL_CHANGE notify type handling to the
4593 server. Affected file silcd/server.c.
4597 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4599 * Added silc_server_send_notify_invite to send the INVITE
4600 notify between routers.
4602 * Implemented the INVITE command correctly to the server.
4604 * Implemented the INVITE notify type handling in the server.
4606 * Implemented the INVITE command to the client library and on the
4609 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4611 * Added function silc_server_get_client_resolve to find the
4612 client entry by ID from all ID lists and then resolve it
4613 (using WHOIS) if it cannot be found. Affected file is
4616 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Implemented the BAN command to the client library.
4620 * The JOIN command in the server now checks the invite list
4623 * Changed the silc_command_reply_payload_encode_va and the
4624 silc_command_payload_encode_va to support that if argument is
4625 NULL it ignores and checks the next argument. Affected file
4626 lib/silccore/silccommand.c.
4628 * Added silc_server_send_notify_ban to send the BAN notify
4629 type between routers.
4631 * Chaned the silc_notify_payload_encode to support that if
4632 argument is NULL it ignores and checks the next argument.
4633 Affected file lib/silccore/silcnotify.c.
4635 * Tested ban lists in router environment successfully.
4637 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4639 * Implemented BAN command to the server, in silcd/command.[ch].
4641 * Removed the BAN and INVITE_LIST modes from the CMODE command
4644 * Added function silc_string_match to regex match two strings.
4645 Affected files lib/silcutil/silcutil.[ch].
4647 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4649 * Redefined parts of the SilcChannelEntry in the server to support
4650 the new ban and invite lists.
4652 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Redefined the INVITE command. The same command can be used to
4655 invite individuals to the channel but also to manage the invite
4656 list of the channel (to add to and remove from the invite list).
4657 Updated the protocol specs.
4659 * Added new command SILC_COMMAND_BAN that can be used to manage
4660 the ban list of the channel. Updated the protocol specs.
4662 * Removed the channel modes: the SILC_CMODE_BAN and the
4663 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4664 in the CMODE command. The equivalent features are now available
4665 using INVITE and BAN commands. Updated the protocol specs.
4667 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4668 in the network about change in the current ban list. The notify
4669 type is not used by the client.
4671 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4672 support the invite lists.
4674 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Added new function silc_string_regexify that converts string
4677 including wildcard characters into regex string that can
4678 be used by the GNU regex library. Added into the file
4679 lib/silcutil/silcutil.[ch].
4681 Added silc_string_regex_combine to combine to regex strings
4682 into one so that they can be used as one regex string by
4683 the GNU regex library. Added into the file
4684 lib/silcutil/silcutil.[ch].
4686 Added silc_string_regex_match to match two strings. It returns
4687 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4689 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4691 * Imported GNU regex to the soruce tree into lib/contrib.
4692 Fixed some compiler warning from the regex.c.
4694 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4696 * Fixed MOTD command in the server to work in router environment.
4698 * Fixed the MOTD command in the client library to support
4699 the server argument in the command.
4701 * Added `nickname_len' argument to the silc_idlist_add_client
4702 in the server, as the `nickname' argument may be binary data
4705 * Added silc_idlist_get_channels to return all channels from
4708 * Implemented LIST command to the server. Affected file is
4711 * Implemented the LIST command to the client library and on the
4714 * Added [<user count>] argument to the LIST command reply.
4715 With private channels the user count is not shown.
4717 * Updated TODO and README.
4719 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4721 * The client entry's data.registered must be TRUE even with
4722 global client entry on global client list. The data.registered
4723 is used to check whether the client is anymore in the network,
4724 for example with WHOWAS command so it must be valid.
4726 * Fixed the WHOWAS command in the server. It now actually works
4727 in router environment. Added function into silcd/command_reply.c
4728 silc_server_command_reply_whowas_save.
4730 * Added silc_idlist_purge function to the silcd/idlist.c
4731 to periodically purge the ID Cache.
4733 * Fixed INFO command in the server. It works now in router
4734 environment. Added <server name> argument to the INFO command
4735 reply. Updated the protocol specs.
4737 * Fixed minor bug in silc_idcache_purge to not purge if the
4738 expire value is zero.
4740 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4741 they were buggy because of the WHOWAS information.
4743 * Fixed local command MSG to handle the async resolving of
4744 the remote client properly. It used to fail the first MSG.
4745 Affected file silc/local_command.c.
4747 * Added `data_len' field to SilcIDCache context.
4749 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4751 * Update TODO. Todo in commands in the server.
4753 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4755 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4756 used by routers as broadcast packet to inform other routers
4757 about the changed user mode.
4759 Implemented the notify handling in the server. Affected file is
4760 silcd/packet_receive.c. Added the function
4761 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4763 * Added new generic Channel Payload and deprecated the New Channel
4764 Payload. The New Channel Payload is now the generic Channel
4767 * Added new argument `mode' to the silc_server_send_new_channel
4768 as it is required in the Channel Payload now.
4770 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4771 and created a new and real SilChannelPayload to represent the
4772 new generic Channel Payload. Implemented the encode/decode
4773 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4775 * Added silc_server_get_client_channel_list to return the list
4776 of channels the client has joined for WHOIS command reply.
4777 Affected file silcd/server.[ch].
4779 * Implemented the channel list sending in the WHOIS command reply
4780 in server and in the client.
4782 Implemented the channel list displaying on the user interface
4783 as well. Affected file silc/client_ops.c.
4785 * Added silc_channel_payload_parse_list to parse list of Channel
4786 Payloads. It returns SilcDList list of SilcChannelPayloads.
4787 Client for example can use this function to parse the list of
4788 channels it receives in the WHOIS command reply. The caller
4789 must free the list by calling silc_channel_payload_list_free.
4790 Affected files lib/silccore/silcchannel.[ch].
4792 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4794 * Added one new argument <user mode> to the WHOIS command reply
4795 to return the mode of the user in SILC. Updated the protocol
4798 Implemented it to the server and client.
4800 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4802 * Fixed the mode printing on the user interface on joining.
4803 Affected file silc/client_ops.c.
4805 * Implemented the UMODE command and user modes in general to the
4806 client library and to the user interface.
4808 * Implemented the UMODE command to the server.
4810 * The server now sends UNKNOWN_COMMAND error status if client sends
4811 unknown command. Affected file silcd/command.c.
4813 * All server commands now handle the command identifier the right
4814 way when sending the command reply to the client. The client can
4815 use to identify the command replies with the identifier.
4817 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4819 * Added silc_server_get_client_route to resolve the route to
4820 the client indicated by the client ID. Affected file is
4823 * Added silc_server_relay_packet as general function to relay
4824 packet to arbitrary destination. This deprecates functions
4825 like _send_private_message_key, _relay_notify etc. Affected
4826 file is silcd/packet_send.[ch].
4828 Removed silc_server_send_key_agreement,
4829 silc_server_send_private_message_key and
4830 silc_server_packet_relay_notify functions from the file
4831 silcd/packet_send.[ch].
4835 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4836 server. Affected file silcd/packet_receive.[ch].
4838 * Implemented the KILL command to the client. Implemented the
4839 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4840 Affected files lib/silcclient/command[_reply].c and
4841 lib/silcclient/client_notify.c. Implemented the KILL notify
4842 printing in the user inteface.
4844 * Fixed a lot silc_parse_nick memory leaks from the client
4845 library in the file lib/silcclient/command.c.
4847 * Changed the silc_server_send_notify_on_channels's `sender'
4848 argument from SilcSocketConnection to SilcClientEntry to
4849 check the sender as entry and not as connection object and not
4850 to send to the client provided as argument. The affected file
4851 is silcd/packet_send.[ch].
4853 * The notify packets that are destined directly to the client used
4854 to not to be processed by the server. Now changed that and the
4855 server processes all notify packets. After relaying the packet
4856 to the client the notify packet is processed in the server.
4858 * The silc_server_free_client_data now checks whether there is
4859 pending outgoing traffic for the client and purges the data to
4860 the network before removing the client entry.
4862 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4864 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4865 an client is killed from the SILC Network. Updated the protocol
4868 Added new function silc_server_send_notify_killed to the
4869 silcd/packet_send.[ch].
4871 * Added function silc_server_packet_relay_notify to relay notify
4872 packets that are destined directly to a client. In this case
4873 the server does not process the notify packets but merely relays
4874 it to the client. Affected file silcd/packet_send.[ch].
4876 Added also silc_server_packet_process_relay_notify to check
4877 whereto relay the notify. Affected file is
4878 silcd/packet_receive.[ch].
4880 * Implemented the KILL command to the server.
4884 * Added the backup schema desgined last fall to the protocol
4885 specs for everyone to see. The specification is in the
4886 *-spec-xx.txt draft and the packet type definitions for the
4887 backup routers is in *-pp-xx.txt draft. Thusly, added also
4888 new packet type SILC_PACKET_CELL_ROUTERS.
4890 * A big security problem in the implementation discovered. The
4891 signoff of an client did not cause new channel key generation
4892 which it of course should've done. The channel keys must be
4893 always re-generated when client leaves (or signoffs) the channel.
4894 The silc_server_remove_from_channels funtion now handles
4895 the channel key re-generation.
4897 * Added `sender' argument to the silc_server_send_notify_on_channels
4898 to not to send the client provided as argument. Affected file
4899 silcd/packet_send.[ch].
4901 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4903 * Implemented OPER and SILCOPER commands into the server and
4906 * Added silc_auth_verify and silc_auth_verify_data to verify
4907 the authentication directly from the authentication payload.
4908 It supports verifying both passphrase and public key based
4909 authentication. Affected file lib/silccore/silcauth.[ch].
4911 * Added `hash' field to the SilcIDListData structure. It is the
4912 hash negotiated in the SKE protocol. Affected file is
4915 * Slight redesigning of the SilcAuthPayload handling routines.
4916 Do not send SilcPKCS but SilcPublicKey as argument.
4918 * Implemented the public key authentication support to the
4919 serverconfig. The public key is loaded from the provided path
4920 and saved as authentication data to void * pointer. Thus,
4921 changed the unsigned char *auth_data to void *auth_data;
4923 * Fixed SHUTDOWN command to send the reply before the server
4924 is shutdown. :) Affected file silcd/command.c.
4926 * Fixed fatal bug in CONNECT command. The hostname was invalid
4927 memory and server crashed. Affected file silcd/command.c.
4929 * Fixed fatal bug in CLOSE command. The server_entry became
4930 invalid but was referenced later in the command. Affected file
4933 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Fixed fatal bug in failure packet handling. Server ignored
4936 the failure and thus crashed when it came.
4940 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4942 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4943 that the command may be executed only once in (about) 2 seconds.
4944 The old SILC_CF_LAG flag is same but allows command bursts up
4945 to five before limiting.
4947 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4948 server code. Various commands now includes the CF_LAG_STRICT
4949 flag to disallow any kind of miss-use of the command.
4951 * Fixed the silc_buffer_unformat to not to allocate any data
4952 if the length of the data is zero. It used to allocate the
4953 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4955 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4957 * Changed the format of AdminConnection configuration section
4958 in the server. Added username of the admin to the format.
4959 Affected files silcd/serverconfig.[ch].
4961 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4962 to return admin configuration data by host, username and/or
4965 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4967 * Implemented WHOWAS command to the server. Added the functions:
4969 silc_server_command_whowas_parse,
4970 silc_server_command_whowas_send_reply,
4971 silc_server_command_whowas_from_client and
4972 silc_server_command_whowas_from_server
4974 * Added <Client ID> argument to the WHOWAS command reply. Updated
4975 the protocol specs accordingly.
4977 * Implemented WHOWAS command and command_reply to the client
4980 Implemented the WHOWAS printing on the user interface.
4982 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4984 * Added new argument to the WHOWAS command reply, the real name.
4985 It is an optional argument. Updated the protocol specs.
4987 * Added SilcIDCacheDestructor callback that is registered when
4988 the SilcIDCache is allocated. The callback is called when
4989 an cache entry in the ID Cache expires, or is purged from the
4990 cache. Added into lib/silccore/idcache.[ch].
4992 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4993 to destruct the client entries when the cache entry expires.
4994 Other ID Cache's in server and in the client library ignores
4997 * If the ID Cache entry's `expire' field is zero then the entry
4998 never expires. Added boolean `expire' argument to the
4999 silc_idcache_add function in the lib/silccore/idcache.[ch].
5000 If it is TRUE the default expiry value is used.
5002 * Added silc_server_free_client_data_timeout that is registered
5003 when client disconnects. By default for 5 minutes we preserve
5004 the client entry for history - for WHOWAS command.
5006 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5008 * Added support to the server to enforce that commands are not
5009 executed more than once in 2 seconds. If server receives
5010 commands from client more frequently, timeout is registered
5011 to process the commands. Affected file silcd/command.c.
5012 Added new function silc_server_command_process_timeout.
5014 * Changed NICK_NOTIFY handling in client library to check that
5015 if the client's nickname was changed, so there is no need to
5016 resolve anything from the server.
5018 * Removed error printing from the WHOIS and IDENTIFY commands.
5019 If error occurs then it is ignored silently in the client library.
5020 The application, however, may map the received error to
5021 human readable error string. The application currently maps
5022 the NO_SUCH_NICKNAME error to string.
5024 * Made the command status message public to the application. Moved
5025 them from lib/silcclient/command_reply.c to
5026 lib/silcclient/command_reply.h. The application can map the
5027 received command status to the string with the
5028 silc_client_command_status_message function.
5030 * Added check to the server to check that client's ID is same
5031 as the Source ID in the packet the client sent. They must
5034 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5036 * Added dist-bzip hook to the Makefile.am to make bzip2
5037 compressed distributions.
5039 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5041 * Server now enforces the maximum length for the nickname and
5042 the channel as protocol specification dictates. 128 bytes for
5043 nickname and 256 bytes for channel name.
5045 * Moved the WHOIS printing to the application. The client libary
5046 does not print out the WHOIS information anymore, the application
5047 must do it. Renamed silc_client_command_reply_whois_print to
5048 the silc_client_command_reply_whois_save.
5050 The client's idle time is also sent to the application now, and
5051 the idle is shown on screen.
5053 * Added silc_client_command_reply_identify_save to save the
5054 received IDENTIFY entries.
5056 * Do not check for channel private keys in message sending and
5057 reception if the channel does not have the PRIVKEY mode set.
5058 Affected file lib/silclient/client_channel.c.
5060 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5063 just surfaced after chaning the JOIN procedure.
5065 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5067 * Added silc_client_get_clients_by_list to get client entries
5068 from Client ID list, that is returned for example by JOIN
5069 and USERS command replies. The application should use this
5070 function for example when JOIN command reply is received to
5071 resolve the clients already on the channel (library does not
5072 do that anymore as USERS command reply is not used in the JOIN
5073 procedure anymore). Affected files lib/silcclient/silcapi.h and
5074 lib/silcclient/idlist.c.
5076 * JOIN command reply and USERS command reply returns now SilcBuffer
5077 pointers instead of unsigned char pointers when returning
5078 the client list and mode list.
5080 * Added <Client ID> argument to the JOIN command reply, mainly
5081 for the server to identify for which client the command was
5082 originally sent. Updated protocol specs accordingly.
5084 * Added SilcDlist private_key pointer to the SilcChannelEntry
5085 in the client to support the channel private keys. Affected
5086 file is lib/silcclient/idlist.h.
5088 * Added SilcChannelPrivateKey argument to the function
5089 silc_client_send_channel_message so that application can choose
5090 to use specific private ke if it wants to. If it is not provided,
5091 the normal channel key is used, unless private keys are set.
5092 In this case the first (key that was added first) is used
5093 as the encryption key.
5095 * Implemented the support for channel private key handling.
5096 Implemented the following functions:
5098 silc_client_add_channel_private_key,
5099 silc_client_del_channel_private_keys,
5100 silc_client_del_channel_private_key,
5101 silc_client_list_channel_private_keys and
5102 silc_client_free_channel_private_keys
5104 Affected file lib/silcclient/client_channel.c.
5106 * Added the support for the private keys in the channel message
5107 sending and encryption and in the message reception and
5108 decryption. Affected funtions are
5109 silc_client_send_channel_message and silc_client_channel_message.
5111 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5113 * Added SKE's key verify callback to the client library's
5114 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5116 * Removed the statement that server (or router) must send USERS
5117 command reply when joining to the channel so that the client
5118 knows who are on the channel. Instead, the client list and
5119 client's mode list is now sent in the JOIN command reply to the
5120 client who joined channel. This is better solution.
5122 * Added function silc_server_get_users_on_channel and function
5123 silc_server_save_users_on_channel to the silcd/server.[ch].
5125 * Removed function silc_server_command_send_users from the
5128 * Do not show topic on the client library anymore. The topic is
5129 sent in the command reply notify to the application and the
5130 application must show the topic now.
5132 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5134 * Added client searching by nickname hash into the IDENTIFY and
5135 WHOIS commands in the server as they were clearly missing from
5136 them. Affected file is silcd/command.c.
5138 * Fixed a bug in private message receiving in the client library.
5139 The remote ID was freed and it wasn't supposed, now it is
5142 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5144 * Minor fix to the channel payload; allocate the data area, as it
5145 needs to be of specific length.
5147 * If the key agreement port is zero then the operating
5148 system will define the bound port. Affected files are
5149 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5151 * Added new function silc_channel_payload_decrypt into the file
5152 lib/silccore/silcchannel.[ch].
5154 * Moved the channel message etc, check from silc_packet_decrypt
5155 to applications. The library calls now a generic
5156 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5157 when the packet is either normal or special. This was done to
5158 allow more wide range of checking that was not allowed when
5159 the code was in library. Now applications can do virtually any
5160 checks to the packet and return to the library the decision how
5161 the packet should be processed. Affected files are
5162 lib/silccore/silcpacket.[ch].
5164 Added silc_server_packet_decrypt_check to the server and
5165 silc_client_packet_decrypt_check to the client library.
5167 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5168 to send with specified source and destination information.
5170 * Channel message delivery between routers was broken after the
5171 channel key distribution was fixed earlier. The channel key
5172 was used be to distributed to other routers as well which is not
5173 allowed by the protocol. Now this is fixed and channel keys
5174 really are cell specific and the channel message delivery between
5175 routers comply with the protocol specification.
5177 * Fixed various commands in server to check also the global list
5178 for the channel entry and not just the local list. The affected
5179 file silcd/command.c.
5181 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5183 * Added assert()s to buffer formatting and unformatting routines
5184 to assert (if --enable-debug) when error occurs. Affected
5185 file: lib/silcutil/silcbuffmt.c.
5187 * Changed to auto-reconnect to check whether the remote host is
5188 router and register the re-connect timeout if it is. It used
5189 to check that whether we are normal server, but router must do
5190 auto-reconnect with another router as well. Affected file
5193 * Removed the [<key len>] option from CMODE command as the cipher
5194 name decides the key length, nowadays. See the defined ciphers
5195 from the protocol specification.
5197 * Added [<hmac>] option to the CMODE command to define the HMAC
5198 for the channel. Added SILC_CMODE_HMAC channel mode.
5200 * Added [<hmac>] option for the JOIN command so that user can
5201 select which HMAC is used to compute the MACs of the channel
5204 * Added Hmac field to the Channel Message Payload. The integrity
5205 of plaintext channel messages are now protected by computing
5206 MAC of the message and attaching the MAC to the payload. The
5207 MAC is encrypted. Now, it is clear that this causes some
5208 overhead to the size of the packet but rationale for this is that
5209 now the receiver can verify whether the channel message decrypted
5210 correctly and also when private keys are set for the channel the
5211 receiver can decrypt the packet with several keys and check from
5212 the MAC which key decrypted the message correctly.
5214 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5215 lib/silccrypt/silccipher.[ch].
5217 * Added silc_hash_len to return the digest length into the
5218 lib/silcrypt/silchash.[ch].
5220 * Rewrote parts of Silc Channel Payload interface in the
5221 lib/silccore/silcchannel.[ch]. The encode function now also
5222 encrypts the packet and parse function decrypts it.
5224 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5226 * Fixed a minor formatting bug in the SKE's key material processing.
5227 It actually might have processed the keys wrong way resulting
5230 * Redefined the mandatory HMAC algorithms and added new algorithms.
5231 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5232 and hmac-md5 truncated to 96 bits. The mandatory is now
5233 hmac-sha1-96. Rest are optional (including the one that used
5234 to be mandatory). Rationale for this is that the truncated HMAC
5235 length is sufficient from security point of view and can actually
5236 make the attack against the HMAC harder. Also, the truncated
5237 HMAC causes less overhead to the packets. See the RFC2104 for
5240 * Added new [hmac] configuration section. The SKE used to use
5241 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5242 is of course wrong. The official names that must be proposed in
5243 the SKE are the ones defined in the protocol specification
5244 (hmac-sha1-96 for example). The user can configure any hmac
5245 using any hash function configured in the [hash] section. At
5246 least, the mandatory must be configured.
5248 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5250 * Added HMAC list to the SKE proposal list. It has now both
5251 hash algorithm list and HMAC list. This makes the protocol
5252 incompatible with previous versions. The SKE now seems to work
5253 the way it is supposed to work, for the first time actually.
5255 * Defined plain Hash algorithms to the protocol specification.
5258 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5260 * Implemented support for key agreement packets into the server.
5261 Added functions silc_server_key_agreement and
5262 silc_server_send_key_agreement. Other than these functions,
5263 server has nothing to do with this packet.
5265 * Added support for private message key packets into the server.
5266 Added functions silc_server_private_message_key and
5267 silc_server_send_private_message_key.
5271 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5272 called in the protocol's final callback instead in the END
5273 protocol state. This makes a little more sense and in the same
5274 time in client we can use the same protocol routines for normal
5275 key exchange and to key agreement packet handling as well.
5277 * Added to both client's and server's KE protocol context the
5278 SilcSKEKeyMaterial pointer to save the key material. We will
5279 bring the key material to the protocol's final callback by doing
5280 this. The final callback must free the key material.
5282 * Added SKE's packet_send callback into client's KE protocol
5283 context so that the caller can choose what packet sending function
5284 is used. This way we can use different packet sending when
5285 doing normal SKE when doing key agreement packet handling (in
5286 the key agreement packet handling we do not want to encrypt
5289 * Implemented the responder side of the key agreement routines
5290 in the client. The client can now bind to specified port and
5291 accept incoming key negotiation. The key material is passed
5292 to the application after the protocol is over.
5294 * Implemented the processing of incoming Key Agreement packet
5295 in the client. Added function silc_client_key_agreement to
5298 * Implemented the intiator side of the key agreement routines
5299 in the client. The client can now initiate key agreement with
5300 another remote client. The key material is passed to the
5301 application after the protocol is over.
5303 * Created client_keyagr.c to include all the key agreement
5306 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5307 SILC_TASK_CALLBACK except that it is not static.
5309 * Created client_notify.c and moved the Notify packet handling
5310 from the client.[ch] into that file.
5312 * Created client_prvmsg.c and moved all private message and
5313 private message key routines from the client.[ch] into that file.
5315 * Create client_channel.c and moved all channel message and
5316 channel private key routines from the client.[ch] into that file.
5318 * Changed silc_client_get_client_by_id_resolve to resolve with
5319 WHOIS command instead of IDENTIFY command, in the file
5320 lib/silclient/idlist.c.
5322 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5324 * Implemented the SKE's responder side to the Client library.
5326 * When FAILURE is received to the protocol do not trust it
5327 blindly. Register a timeout to wait whether the remote closes
5328 the connection as it should do it, only after that process the
5329 actual failure. This was changed to both client and server.
5331 * Added client_internal.h to include some of the structures
5332 there instead of client.h in lib/silcclient/.
5334 * Added function silc_task_unregister_by_callback to unregister
5335 timeouts by the callback function.
5337 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * Some "Incomplete WHOIS info" errors has been appearing on the
5340 log files. Took away the entry->userinfo check from WHOIS
5341 reply sending. The entry->userinfo is now " " if client did not
5342 provide one. I thought this was fixed earlier but something
5343 is wrong still. Let's see if the error still appears.
5345 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5347 * Fixed a minor bug in the login when the channel key is
5348 re-generated in the server. It used to generate the key in
5349 wrong order and thus caused problems in the channel traffic.
5351 * Fixed a minor bug in channel key distsribution after
5352 KICK command. The key was not sent to the router even though
5355 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5357 * Added silc_ske_process_key_material_data as generic routine
5358 to process any key material as the SILC protocol dictates. The
5359 function is used by the actual SKE library but can be used by
5360 applications as well. This relates to the private message keys
5361 and the channel private keys since they must be processed the
5362 same way the normal SILC session keys. The protocol dictates
5363 this. Affected files: lib/silcske/silcske.[ch].
5365 Added also silc_ske_free_key_material to free the
5366 SilcSKEKeyMaterial structure.
5368 * Defined silc_cipher_set_key function to set the key for
5369 cipher without using the object's method function. The affected
5370 files: lib/silccrypt/silccipher.[ch].
5372 * Implemented silc silc_client_add_private_message_key,
5373 silc_client_add_private_message_key_ske,
5374 silc_client_del_private_message_key,
5375 silc_client_list_private_message_keys and
5376 silc_client_free_private_message_keys functions in the
5379 Added functions silc_client_send_private_message_key to send
5380 the Private Message Key payload and silc_client_private_message_key
5381 to handle incoming Private Message Key payload.
5383 * Added Cipher field to the Private Message Key payload to set
5384 the cipher to be used. If ignored, the default cipher defined
5385 in the SILC protocol (aes-256-cbc) is used.
5387 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5389 * Removed lib/silcclient/ops.h file.
5391 Redefined parts of the SILC Client Library API. Created new
5392 file silcapi.h that deprecates the ops.h file and defines the
5393 published Client Library API. Defined also private message key
5394 API and channel private key API into the file.
5396 This is the file that the application must include from the
5397 SILC Client Library. Other files need not be included by
5398 the application anymore.
5400 * Added new key_agreement client operation callback and also
5401 defined the Key Agreement library API for the application.
5403 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5405 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5406 is used by clients to request key negotiation between another
5407 client in the SILC network. If the negotiation is started it
5408 is performed using the SKE protocol. The result of the
5409 negotiation, the secret key material, can be used for example
5410 as private message key.
5412 Implemented the Key Agreement payload into the files
5413 lib/silccore/silauth.[ch].
5415 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5417 * Redefined ciphers for the SILC protocol. Added some new ciphers
5418 and defined the key lengths for the algorithms. Changed the
5419 code accordingly. The default key length is now 256 bits.
5421 * Fixed SKE key distribution function silc_ske_process_key_material
5422 when the key length is more than 128 bits. The default key
5423 length in SILC is now 256 bits.
5425 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5426 to indicate unsupported algorithm.
5428 * Renamed rijndael.c to aes.c and all functions as well.
5430 * Fixed a long standing channel key setting bug in client library.
5431 Weird that it has never surfaced before.
5433 * Fixed bug in channel deletion. If the entire channel is removed
5434 then it must also delete the references of the channel entry
5435 from the client's channel list as the client's channel entry and
5436 the channel's client entry share same memory.
5438 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5440 * Implemented CONNECT and SHUTDOWN commands in the client.
5442 * Implemented CLOSE command to the client.
5444 * Added the function silc_idlist_find_server_by_name into the
5445 files silcd/idlist.[ch].
5447 Added the function silc_idlist_find_server_by_conn into the
5448 files silcd/idlist.[ch].
5450 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5452 * DIE command was renamed to SHUTDOWN. Updated the both code
5455 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5456 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5458 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5461 * Added function silc_server_create_connection function to create
5462 connection to remote router. My server implementation actually
5463 does not allow router to connect to normal server (it expects
5464 that normal server always initiates the connection to the router)
5465 so the CONNECT command is only good for connecting to another
5468 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5470 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5471 or some other client was kicked from the channel.
5473 Implemented the handling of the notify type to both client
5476 Implemented silc_server_send_notify_kicked to send the KICKED
5477 notify. It is used to send it to the server's primary router.
5479 * Implemented the KICK command into server and client.
5481 * Added `query' argument to the silc_idlist_get_client function
5482 to indicate whether to query the client from server or not if
5485 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5486 to indicate that the client is not channel founder.
5490 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5492 * Removed the rng context from SilcPacketContext structure and
5493 changed that the packet routine uses the Global RNG API.
5495 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5497 * Added support for quit message that client can "leave" on the
5498 channel when it quits the SILC. It is ditributed inside the
5499 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5501 Added silc_server_free_client_data that will take the
5502 signoff message as argument.
5504 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5506 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5508 * Updated parts of the protocol specification to keep it up
5511 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5513 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5514 payloads in one packet.
5516 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5517 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5518 use now the new List flag.
5520 * Also deprecated the following packet types: REPLACE_ID,
5521 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5523 * Added list support for Notify packet in server.
5525 * Added silc_server_send_notify_channel_change to send the
5526 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5527 the silc_server_send_replace_id.
5529 * Added silc_server_send_notify_nick_change to send the
5530 NICK_CHANGE notify type. Deprecates the function
5531 silc_server_send_replace_id.
5533 * Added silc_server_send_notify_join to send the JOIN notify type.
5534 Deprecates the function silc_server_send_new_channel_user.
5536 * Added silc_server_send_notify_leave to send LEAVE notify type.
5537 Deprecates the function silc_server_send_remove_channel_user.
5539 * Added silc_server_send_notify_cmode and
5540 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5541 types. Deprecates the silc_server_send_set_mode function.
5543 * Added SERVER_SIGNOFF notify type to indicate that server has
5544 quit. This means that all clients on the channel from that
5545 server will drop. This can be also used when netsplit happens.
5547 Deprecated REMOVE_ID packet type since it is not needed anymore
5550 Added silc_server_send_notify_server_signoff to send the
5551 SERVER_SIGNOFF notify type. Deprecates the function
5552 silc_server_send_remove_id.
5554 Added also silc_server_send_notify_signoff to send the
5555 SIGNOFF notify type.
5557 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5558 SILC protocol from this day on. Changed the protocol
5559 specification as well.
5561 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5562 notify type. It is used between routers to notify about
5563 topic changes on a channel.
5565 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5568 * Partly updated the protocol specification to comply with the
5569 changes now made. It is still though a bit outdated.
5571 * The JOIN notify type now takes one extra argument <Channel ID>.
5572 The packet used to be destined to the channel but now the
5573 JOIN type may be sent as list thus it is impossible to
5574 destine it to any specific channel. By adding this argument
5575 it is again possible.
5577 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5579 * Added CREDITS file. The CHANGES and CREDITS file will appear
5580 in the distribution as well.
5582 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5584 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5585 types in the server's silcd/packet_receive.c.
5587 * Implemented CMODE and CUMODE to work in router environment.
5589 * Fixed minor encoding and decoding buglet from the
5590 lib/silccore/silcmode.c.
5592 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5595 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5597 * Changed all SilcConfigServer* and silc_config_server* to
5598 SilcServerConfig* and silc_server_config*, respectively.
5601 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5603 * Associated the ID (client or server ID) to the Authentication
5604 Payload to avoid any possibility of forging. Updated the
5605 protocol specification and the code accordingly.
5607 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * The RSA key length is now save to the RsaKey context in the
5610 key generation process in lib/silccrypt/rsa.c. The key length
5611 is now used to figure out the maximum size of the block allowed
5612 to be encrypted/signed.
5614 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5615 is equivalent to the silc_mp_mp2bin but does not allocate any
5618 * Changed silc_mp_mp2bin API to take length argument. If it is
5619 non-zero then the buffer is allocated that large. If zero, then
5620 the size is approximated using silc_mp_sizeinbase, which however
5623 * Created Global RNG API which is global RNG that application can
5624 initialize. After initializing, any routine anywhere in the
5625 code (including library) can use RNG without allocating a new
5626 RNG object. This was done to allow this sort of use of the
5627 RNG in code that has no chance to allocate RNG object. All
5628 applications currently allocate this and many routines in the
5629 library use this. Affected file lib/silccrypt/silcrng.[ch].
5631 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5632 it to use the Global RNG API.
5634 * Defined Authentication Payload into protocol specification that
5635 is used during SILC session to authenticate entities. It is
5636 used for example by client to authenticate itself to the server
5637 to obtain server operator privileges.
5639 Implemented this payload into the lib/silccore/silcauth.[ch].
5640 Implemented also routines for public key based authentication
5641 as the new protocol specification dictates.
5643 Moved definitions of different authentication methods from
5644 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5646 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5647 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5648 silc_pkcs_verify_with_hash functions into the file
5649 lib/silccrypt/silcpkcs.[ch].
5651 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5653 * The client entry's userinfo pointer must be always valid.
5654 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5655 will fail since it requires the userinfo. Now, the userinfo
5656 is allocated as "" if actual userinfo does not exist. Actually,
5657 it must exist and it is totally Ok to drop client connections
5658 that does not announce the userinfo. However, we will make
5659 this workaround for now.
5661 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5662 to return the remote port by socket.
5664 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5666 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5667 SILC_SERVER_PENDING_EXEC and added an new macro
5668 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5669 data or when error occurs while processing the pending command.
5671 Added new argument `destructor' into silc_server_command_pending
5672 and to the SilcServerCommandPending object. This destructor is
5673 now called after calling the pending callback or if error occurs
5674 immediately. If error occurs the actual pending callback won't
5675 be called at all - only the destructor. The destructor may be
5676 NULL if destructor is not needed.
5678 All this applies for client library code as well. Similar
5679 changes were made there as well for the pending commands.
5681 In the client, the application must now allocate the
5682 SilcClientCommandContext with the silc_client_command_alloc
5685 * Added reference counter to the SilcServerCommandContext. Added
5686 function silc_server_command_alloc and silc_server_command_dup
5689 Same type of functions added to the client library for the same
5692 * Removed the cmd_ident from IDListData away since it is now
5693 global for all connections. It is the command identifier used
5694 in command sending and with pending commands. The affected file
5697 * Added reference counter to the SilcSocketConnection objecet to
5698 indicate the usage count of the object. The object won't be
5699 freed untill the reference counter hits zero. Currently only
5700 server uses this, and client ignores it. The client must be
5701 set to use this too later. The affected files are
5702 lib/silccore/silcsockconn.[ch]. Added also the function
5703 silc_socket_dup to increase the reference counter.
5705 This was mainly added because it is possible that the socket
5706 is removed underneath of pending command or other async
5707 operation. Now it won't be free'd and proper DISCONNECTING
5708 flags, etc. can be set to avoid sending data to connection that
5709 is not valid anymore.
5711 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5712 the connection. After that it sets SILC_SET_DISCONNECTED.
5713 It is, however, possible that the socket data is not still freed.
5714 The silc_server_packet_process now checks that data is not
5715 read or written to connection that is DISCONNECTED. The socket
5716 get's freed when the reference counter hits zero.
5718 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5720 * Changed the client operation API: channel_message operation's
5721 `sender' is now the client entry of the sender, not the nickname
5722 and the `channel' is the channel entry, not the channel name.
5724 In the private_message operation the `sender' is now also the
5725 client entry of the sender not the nickname.
5727 Affected file is lib/silcclient/ops.h and all applications
5728 using the client operations.
5730 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5732 * Moved the calling of ops->connect() from connect_to_server_final
5733 into receive_new_id functin since that is the point when the
5734 client is actually allowed to send traffic to network. The
5735 affected file is lib/silcclient/client.c.
5737 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5739 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5740 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5741 (if needs broadcasting) instead of broadcasting the packets one
5742 by one which would make a burst in the network traffic.
5744 * Added `broadcast' argument to the functions in silcd/server.[ch]
5745 silc_server_create_new_channel[_with_id] to indicate whether
5746 to send New Channel packet to primary router.
5748 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5750 * Added new function into the silcd/server.[ch] files:
5751 silc_server_create_new_channel_with_id to create new channel with
5752 already existing Channel ID.
5754 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5755 lib/silccore/silcpacket.h. This packet is used t send list of
5756 Set Mode payloads inside one packet. Server uses this to set
5757 the modes for the channels and clients on those channels, that it
5758 announced to the router when it connected to it. The protocol
5759 specification has been updated accordingly.
5761 * The silc_server_new_channel did not handle the packet coming
5762 from normal server as it normally does not send that. However,
5763 when it announces its channels it does send it. Implemented
5764 the support for that.
5766 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5767 into the file lib/silccore/id.h.
5769 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5771 * Fixed memory leaks in the functions silc_idlist_del_client,
5772 silc_idlist_del_channel and silc_idlist_del_server in the file
5773 silcd/idlist.c. All of those leaked like a sieve.
5775 * Fixed some small memory leaks in the client's function
5776 silc_client_notify_by_server.
5778 * Added functions into silcd/server.c: silc_server_announce_clients,
5779 silc_server_announce_channels and silc_server_announce_server.
5780 These functions are used by normal and router server to announce
5781 to its primary router about clients, channels and servers (when
5782 router) that we own. This is done after we've connected to the
5785 These functions effectively implements the following packet types:
5786 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5787 and SILC_PACKET_NEW_ID_LIST.
5789 * Added new functions into the silcd/packet_receive.[ch]:
5790 silc_server_new_id_list, silc_server_new_channel_list and
5791 silc_server_new_channel_user_list to handle the incoming
5792 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5794 * Added support of changing Channel ID in the function
5795 silc_server_replace_id. If the server that announces a channel
5796 to the router already exists in the router (with same name but
5797 with different Channel ID), router is responsible to send
5798 Replace ID packet to the server and force the server to change
5799 the Channel ID to the one router has.
5801 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5802 client that the Channel ID has been changed by the router. The
5803 normal server sends this to the client. Client must start using
5804 the new Channel ID as the channel's ID.
5806 Implemented handling of this new type into lib/silcclient/client.c
5807 into the function silc_client_notify_by_server.
5809 * Added new function silc_idlist_replace_channel_id into the files
5810 silcd/idlist.[ch] to replace the Channel ID.
5812 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5814 * Call silc_server_command_identify_check always when processing
5815 the IDENTIFY command in silcd/command.c
5817 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5819 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5820 send keepalive packets. The packet can be sent by clients,
5821 servers and routers.
5823 Added function silc_socket_set_heartbeat into the file
5824 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5825 If not set, the heartbeat is not performed. The actual
5826 heartbeat is implemented in the low level socket connection
5827 library. However, application is responsible of actually
5830 Added silc_server_send_heartbeat to send the actual heartbeat
5831 packet into silcd/packet_send.[ch]. Server now performs
5832 keepalive with all connections.
5834 * Added silc_task_get_first function into lib/silcutil/silctask.c
5835 to return the timeout task with shortest timeout. There was a bug
5836 in task unregistration that caused problems. TODO has been
5837 updated to include that task system must be rewritten.
5839 * The client library will now resolve the client information when
5840 receiving JOIN notify from server for client that we know but
5841 have incomplete information.
5843 * Rewrote parts of silc_server_remove_from_channels and
5844 silc_server_remove_from_one_channel as they did not remove the
5845 channel in some circumstances even though they should've.
5847 * Encryption problem encountered in server:
5849 The LEAVE command used to send the Channel Key packet to the
5850 router immediately after generating it. However, the code
5851 had earlier sent Remove Channel user packet but not immediately,
5852 ie. it was put to queue. The order of packets in the router
5853 was that Channel Key packet was first and Remove Channel User
5854 packet was second, even though they were encrypted in the
5855 reverse order. For this reason, MAC check failed. Now, this
5856 is fixed by not sending the Channel Key packet immediately but
5857 putting it to queue. However, this is more fundamental problem:
5858 packets that are in queue should actually not be encrypted
5859 because packets that are sent immediately gets encrypted
5860 actually with wrong IV (and thus MAC check fails). So, packets
5861 that are in queue should be encrypted when they are sent to
5862 the wire and not when they put to the queue.
5864 However, the problem is that the current system has not been
5865 designed to work that way. Instead, the packet is encrypted
5866 as soon as possible and left to the queue. The queue is then
5867 just purged into wire. There won't be any fixes for this
5868 any time soon. So, the current semantic for packet sending
5871 o If you send packet to remote host and do not force the send
5872 (the packet will be in queue) then all subsequent packets to the
5873 same remote host must also be put to the queue. Only after the
5874 queue has been purged is it safe again to force the packet
5877 o If you send all packets immediately then it safe to send
5878 any of subsequent packets through the queue, however, after
5879 the first packet is put to queue then any subsequent packets
5880 must also be put to the queue.
5882 Follow these rules and everything works fine.
5884 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5886 * Added new function silc_server_remove_clients_by_server to
5887 remove all client entries from ID list when the server connection
5888 is lost. In this case it is also important to invalidate all
5889 client entires as they hold the invalid server entry. This
5890 fixes fatal bug when server has lost connection and will reconnect
5893 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5895 * Made some sanity checks to silc_server_daemonise like to check
5896 whether the requested user and group actually exists.
5898 * Added sanity check to SKE's silc_ske_responder_finish to check
5899 that the public and private key actually is valid.
5901 * Invalidate the client's nickname when receiving Replace ID
5902 packet and the Client ID is being replaced. This means that the
5903 server will query the nickname if someone needs it (client)
5906 * Sort the ID Cache in client library when the ID Cache data
5907 has changed (needs sorting).
5909 * Do not allow for SILC client to create several connections to
5910 several servers. The client does not support windows right now
5911 and generating multiple connections causes weird behaviour.
5913 Irssi-silc client does support windows and can handle several
5914 connections without problems, see: www.irssi.org and SILC plugin.
5916 * Fixed some places where client was added to the IDList. The
5917 rule of thumb is following (in order to get everything right):
5918 If the client is directly connected local client then the
5919 `connection' argument must be set and `router' argument must be
5920 NULL to silc_idlist_add_client function. If the client is not
5921 directly connected client then the `router' argument must
5922 bet set and the `connection' argument must be NULL to the
5923 silc_idlist_add_client function.
5925 * The funtion silc_server_packet_send_local_channel actually did
5926 not check whether the client was locally connected or not. It
5927 does that now. Fixed a bug related to LEAVE command.
5929 * Fixed Remove Channel User payload parsing bug in server's
5930 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5932 * The server's silc_server_save_channel_key now checks also the
5933 global ID list for the channel as it might not be in the local
5934 list. Fixed a bug related to LEAVE command.
5936 * Is this the end of the [<unknown>] buglet that has been lurking
5937 around for a long time? A little for loop fix in server's
5938 silc_server_command_whois_parse that is used by both IDENTIFY
5939 and WHOIS command. At least, this was a clear bug and a cause
5940 of one type of [<unknown>] buglet.
5942 * WHOIS and IDENTIFY commands call the function
5943 silc_server_command_[whois/identify]_check function even if
5944 we are not router server.
5946 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5948 * Added --with-gmp configuration option. If set the GMP
5949 is always compiled in the SILC source tree. If not set then
5950 it is checked whether the system has the GMP3 installed. If
5951 it has then the GMP won't be compiled (the system's headers
5952 and library is used), if it doesn't have it then the GMP is
5953 compiled in the SILC source tree.
5955 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5957 * Changed RSA private exponent generation to what PKCS #1
5958 suggests. We try to find the smallest possible d by doing
5959 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5960 not security fix but optimization.
5962 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5964 * Added new config entry [Identity] to fork the server and run
5965 it as specific user and group. A patch from Bostik.
5967 * Imported Dotconf configuration library into lib/dotconf.
5968 This will be used to create the SILC configuration files later.
5969 It will appear in the distsribution after this commit.
5971 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * A big code auditing weekend happening. Auditing code for
5974 obvious mistakes, bugs and errors. Also, removing any code
5977 Removed files for being obsolete:
5979 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5980 inline in the file lib/silcutil/silcbuffer.h)
5982 o lib/silcutil/silcbufutil.c (the header has inline versions)
5984 Changed code to fix possible error conditions:
5986 o The buffer formatting routines now check that the destination
5987 buffer really has enough space to add the data. This applies for
5988 both buffer formatting and unformatting
5989 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5990 unformatting was changed to accomodate following rules:
5991 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5992 sent to the function while XXX_*STRING will not allocate or copy
5993 the data into the buffer. Instead it sets the pointer from the
5994 buffer into the pointer sent as argument (XXX_*STRING used to
5995 require that the pointer must be allocated already). This change
5996 makes this whole thing a bit more consistent and more optimized
5997 (note that the data returned in the unformatting with XXX_*STRING
5998 must not be freed now). The routines return now -1 on error.
6000 o Tried to find all code that use buffer_format and buffer_unformat
6001 and added return value checking to prevent formatting and
6002 especially unformatting errors and possible subsequent fatal
6005 o Changed ske->x and ske->KEY to mallocated pointers in
6006 lib/silcske/silcske.h. Fixed possible data and memory leak.
6008 o Added return value checking to all *_parse* functions. Fixed
6009 many memory leaks as well.
6011 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6012 so that buffer overflows would not happen. All code now also
6013 checks the return value as it can fail.
6015 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6017 * Added reconnection support to server if the normal server looses
6018 its connection to the router (for example if router is rebooted).
6019 The server performs normal reconnection strategy implemented
6020 to the server. Affected file silcd/server.c.
6022 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6024 * Added new packet type SILC_PACKET_SET_MODE that is used to
6025 distribute the information about changed modes (for clients,
6026 channels and clients channel modes) to all routers in the
6027 network. Updated the protocol specification accordingly.
6029 Added functions into silcd/packet_send.c and
6030 silcd/packet_receive.c: silc_server_send_set_mode,
6031 silc_server_set_mode.
6033 Added new files silcmode.[ch] into lib/silccore that implements
6034 the encoding and decoding of Set Mode Payload. Added new type
6035 SilcSetModePayload. Moved the definitions of different modes
6036 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6038 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6040 * Oops, a little mistake in server's connection authentication
6041 protocol. The protocol is not ended with FAILURE but with
6042 SUCCESS if the authentication is Ok. :) Affected file is
6045 * Implemented NICK_CHANGE notify handling in server in the file
6046 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6047 the local clients on the channel. After the changing nickname
6048 in router environment snhould work and the [<unknown>] nickname
6049 should appear no more.
6051 The silc_server_replace_id function that receives the Replace ID
6052 payload now sends the NICK_CHANGE notify type also in the file
6053 silcd/packet_receive.c
6055 * Changed WHOIS and IDENTIFY command to support the maximum amount
6056 of arguments defined in protocol specs (3328 arguments). This
6057 fixed a bug that caused problems when there were more than three
6060 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6062 * Added extra parameter, command identifier, to the
6063 silc_client_send_command so that explicit command identifier
6066 Changed that ID list routines uses specific command identifier
6067 when sending WHOIS/IDENTIFY requests to the server so that they
6068 can be identified when the reply comes back.
6070 Affected files lib/silcclient/command.[ch],
6071 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6073 * Added `sender' argument to silc_server_packet_send_to_channel
6074 to indicaet the sender who originally sent the packet to us
6075 that we are now re-sending. Ignored if NULL. Affected file
6076 silcd/packet_send.[ch].
6078 * Added some server statistics support in silcd/server_internal.h
6079 SilcServerStatistics structure and around the server code. Also
6080 send some nice statistics information when client is connecting
6083 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6085 * Fixed channel ID decoding in server's JOIN command reply in
6086 silcd/command_reply.c
6088 * Fixed braodcasting of replace ID payload to not to send it if
6089 we are standalone server in silcd/packet_receive.c.
6091 * Fixed all channel message sending routines to not to send
6092 packets to clients that has router set, since they are routed
6093 separately in the same function earlier. Affects file
6094 silcd/packet_send.c and all channel packet sending functions.
6096 * In USERS reply, res_argv[i] are not allocated, the table
6097 is allocated. Thus changed that free the table, not its
6100 * In server's whois_check and identify_check if the client is
6101 locally connected do not send any WHOIS commands - they are not
6104 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6106 * Fixed some minor bugs in client when sending WHOIS command. The
6107 arguments was in wrong order.
6109 * Removed statis function add_to_channel from server in
6110 silcd/command.c that was previously used with the joining but
6113 * Tested USERS command in router environment successfully with two
6114 routers, two servers and two clients.
6116 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6118 * Reorganized the USERS command and command reply in client library
6119 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6120 When the command is given by user we register a pending command
6121 callback that will reprocess the command after the reply has been
6122 received from the server. When reprocessing the packet we then
6123 display the information. Thus, the USERS information is displayed
6124 now in the command callback instead of in the command reply
6125 callback. The processing of the command is same as previously
6126 when server has sent the command reply in the JOINing process.
6128 * Added to USERS command in silcd/command_reply.c to join the client,
6129 we didn't use to know about, to the channel after we've created
6130 a client entry for it. Also, for clienet we did know already still
6131 check whether it is on the channel or not and add it if not.
6133 * Removed silc_server_command_join_notify as the function and its
6136 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6138 * Changed the client's pending command handling to the same as the
6139 server's pending command handling. It is also now possible to
6140 execute command reply functions from other command reply
6141 function as the function callbacks for commands and command
6142 replies are one and same. The pending commands are not static
6143 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6144 in client connection context. Thus, pending commands are server
6145 connection specific as it is convenient.
6147 Changed the function silc_client_command_pending and
6148 silc_client_command_pending_del and added new function
6149 silc_client_command_pending_check. Removed the
6150 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6153 * Added cmd_ident, current command identifier, to the client
6154 connection context in lib/silcclient/client.h to keep track on
6155 command identifiers used in command sending. Client's command reply
6156 function handling now supports the mandatory command identifiers.
6158 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6159 funtions in client to fully support pending command callbacks.
6161 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6162 as one of the arguments to the application in the command reply
6165 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6166 before first releasing SILC but came back. Now it is removed again
6167 and should come back nomore. The FORWARDED flag was used only
6168 by the JOINing procedure by forwarding the command packet to router.
6169 Now, the JOINing procedure has been changed to more generic (due
6170 to various router environment issues) and FORWARDED is not needed
6171 anymore for anything. The protocol specification is yet to be
6174 Now, removed silc_server_packet_forward from server and the flag
6175 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6177 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6179 * Renamed NAMES command to USERS command. The NAMES was named that
6180 due to historical reasons. Now it is renamed. Also, rewrote
6181 parts of the USERS command. The nickname list is not sent anymore
6182 by the server. Only Client ID and mode lists are sent in the USERS
6183 command. Changed this also to the protocol specification.
6185 The client now resolves the names and stuff after it receives
6186 the USERS list from the server when joining to the channel.
6188 * WHOIS and IDENTIFY commands has been changed to support multiple
6189 Client ID's per command. One can now search for multiple users
6190 in the network by sending only one WHOIS or IDENTIFY command.
6191 Changed the code and the protocol specifications.
6193 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6194 uses silc_server_command_whois_parse to parse the request. */
6196 * If normal server, do not parse the WHOIS and IDENTIFY requests
6197 before sending it to the router. Saves some time.
6199 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6201 * Fixed JOIN command on client library. Wrong number of arguments
6202 used to crash the client.
6204 * Added silc_server_channel_has_global function to check whether
6205 channel has global users or not.
6207 * Added silc_server_channel_has_local function to check whether channel
6208 has locally connected clients on the channel.
6210 * The silc_server_remove_from_one_channel now checks whether the
6211 channel has global users or not after given client was removed from
6212 the channel. It also checks whether the channel has local clients
6213 on the channel anymore. If it does not have then the channel entry
6214 is removed as it is not needed anymore.
6216 * The silc_server_notify now checks on JOIN notify whether the joining
6217 client is one of locally connected or global. If it is global then
6218 the channel has now global users on the channel and that is marked
6219 to the channel entry. Also, it now saves the global client to
6220 global list who is joining and JOINs it to the channel. This is
6221 for normal server, that is.
6223 Changed silc_server_send_notify_on_channel,
6224 silc_server_packet_relay_to_channel and
6225 silc_server_packet_send_to_channel check if we are normal server
6226 and client has router set (ie. global client) do not send the
6227 message to that client, as it is already routed to our router.
6229 * Implemented LEAVE notify type handling in silc_server_notify
6232 * Tested LEAVE command in router environment successfully. Tested
6233 with two routers, two servers and two clients.
6237 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6239 * Implemented SIGNOFF notify type handling in silc_server_notify
6242 * silc_server_remove_id now removes the client entry from all channels
6243 it has joined and thusly sends SIGNOFF notify type.
6245 * Rewrote the NAMES list generation in server by removing two excess
6246 loops. The lists are created now inside one loop.
6248 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6250 * silc_server_remove_channel_user checks now also global list
6251 for channel and client.
6253 * silc_server_new_channel_user checks now both local and global
6254 list for channel and client. Fixed a bug in client id decoding.
6255 Used to decode wrong buffer.
6257 * silc_server_channel_message checks now both local and global
6258 list for channel entry.
6260 * Tested channel joining (hence JOIN) in router environment
6261 successfully. Tested with two routers, two servers and two
6264 * Tested channel message sending in router environment successfully.
6266 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6268 * Added silc_server_save_channel_key into server.[ch] to save the
6269 received channel key in Channel Key payload processing. It is
6270 also used in JOIN command reply handling.
6272 Equivalent function silc_client_save_channel_key added into
6273 client.[ch] into client library.
6275 * Changed JOIN command reply to send information whether the channel
6276 was created or not (is existing already) and the channel key
6277 payload. Changed protocol specs accordingly.
6279 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6280 the request was sent by ID and not by nickname. Crashed on
6283 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6285 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6286 now correctly save the received data.
6288 * silc_server_free_sock_user_data now notifies routers in the
6289 network about entities leaving the network.
6291 At the same time implemented functions silc_server_remove_id
6292 and silc_server_send_remove_id to receive and send REMOVE_ID
6293 packets. The packet is used to notify routers in the network
6294 about leaving entities. The ID removed will become invalid in
6297 * Added function silc_idlist_del_server into server. Removes and
6298 free's server entry from ID list.
6300 * silc_server_private_message function now checks, if we are router,
6301 that the destination ID really is valid ID, naturally.
6303 * In router when NEW_ID packet is received (for new client) the
6304 hash of the Client ID is saved in the ID Cache but the
6305 client->nickname is set to NULL, instead of putting the hash
6308 IDENTIFY command now also checks that client->nickname must be
6309 valid. If it is not if will request the data from the server who
6310 owns the client. Added new function
6311 silc_server_command_identify_check.
6313 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6314 to set the command to already allocated Command Payload.
6316 * Tested private message sending in router environment with two
6317 routers, two servers and two clients. Fixed minor bugs and now
6320 * Fixed segfault from client's NAMES command. Used to crash if
6323 * Forwarded packets must not be routed even if it is not destined
6324 to the receiver. Changed server code comply with this.
6326 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6328 * Added `require_reverse_mapping' boolean value to ServerParams
6329 structure. If TRUE (not default) the server will require that
6330 the connecting host has fully qualified domain name.
6332 If the reverse mapping is not required and hostname could not be
6333 found the IP address is used as hostname.
6335 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6337 * Implemented version string checking to both client and server.
6338 The check is incomplete currently due to the abnormal version
6339 strings used in development version of SILC.
6341 * Changed all command functions in server to use the new
6344 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6346 * Changed char *data to unsigned char *data in ID Cache system to
6347 support binary data as ID Cache data. Changed code to support
6348 binary data in lib/silccore/idcache.c.
6350 * Renamed silc_server_packet_relay_command_reply to
6351 silc_server_command_reply as it is normal packet receiving
6352 function. Rewrote the function to accept command replys for
6353 servers and not only for clients.
6355 * Mark remote router always as registered server if we are connecting
6356 to it. Otherwise, commands sent by the router to us are ignored.
6358 * All ID List find routines now returns the ID Cache Entry pointer
6359 as well if requested.
6361 * WHOIS command works now in router environment, tested with two
6362 routers, two servers and two clients.
6364 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6365 in router environment (as it is almost equivalent to WHOIS) but
6366 hasn't been tested thoroughly. Added new functions:
6368 silc_server_command_identify_parse
6369 silc_server_command_identify_send_reply
6370 silc_server_command_identify_from_client
6371 silc_server_command_identify_from_server
6373 * Disabled route cache adding because adding two different ID's with
6374 same IP replaces the old cache entry thus giving wrong route.
6375 The entry->router->connection is always the fastest route anyway
6376 so route cache may not be needed. Of course, new routes maybe
6377 established after receiving the ID when the entry->router->connection
6378 might not be anymore the most optimal.
6380 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6382 * Add route cache for received ID for fast routing.
6384 * Added silc_server_packet_route to route received packet on router
6385 that is not destined to us.
6387 * Renamed silc_server_get_route to silc_server_route_get.
6389 * Added id_string and id_string_len fields into SilcServer to
6390 include encoded ServerID for fast comparing without excess
6391 encoding of the ID's.
6393 * Cleaned up WHOIS command on server side. Added following static
6396 silc_server_command_whois_parse
6397 silc_server_command_whois_check
6398 silc_server_command_whois_send_reply
6399 silc_server_command_whois_from_client
6400 silc_server_command_whois_from_server
6402 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6403 arguments in command replies. All command functions should be
6404 updated to use this macro.
6406 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6408 * Minor typo fixes on command reply handling on server.
6410 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6412 * Added silc_server_command_add_to_channel internal routine to add
6413 the client to the channel after router has created the channel and
6414 sent command reply to the server.
6416 * Added generic silc_server_send_command to send any command from
6419 * Use static buffer with ID rendering instead of duplicating data.
6421 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6423 * Fixed a channel user mode bug when joining to a channel server gave
6424 everybody channel founder rights, oops.
6426 * We mark ourselves as the router of the incoming server connection
6427 if we are router ourselves. This way we can check in some packet
6428 sending functions whether it is locally connected server. For
6429 incoming router connections we put NULL.
6431 * For router sending packets locally means now always sending the
6432 packet cell wide; to local clients and local servers. For normal
6433 server sending packet locally means sending it to only local
6436 * Fixed the JOIN command to really work in router environment. If the
6437 channel is created it is always created by the router. Router is
6438 also responsible of making the initial joining to the channel,
6439 sending JOIN notify to the sending server and distributing
6440 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6441 does not exist server doesn't do anything else but forward the
6442 command to the router which performs everything.
6444 * Added silc_server_send_channel_key function to send the Channel Key
6447 * Added silc_server_create_channel_key to create new channel key. The
6448 channel key is now re-generated everytime someone joins or leaves
6449 a channel, as protocol dictates. Note: channel->key_len is the
6452 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6454 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6455 packet_receive.[ch] to separate packet sending and receiving
6456 routines. The server.[ch] now includes everything else including
6457 actual packet processing (writing and reading data) and other
6460 Renamed silc_server_private_message_send_internal to
6461 silc_server_send_private_message. The routine is still though
6462 used only to relay private messages as server does not send
6463 private messages itself.
6465 Renamed silc_server_new_channel to silc_server_create_new_channel
6466 and added new function sicl_server_new_channel that handles the
6467 incoming New Channel packet. Added also new sending function
6468 silc_server_send_new_channel to send New Channel Payload.
6470 * Added new function silc_server_notify to process incoming notify
6471 packet to the server/router. Server may then relay the notify
6472 to clients if needed.
6474 * Added new function silc_server_new_channel_user to process incoming
6475 New Channel User packet. Router will redistribute the packet and
6476 send JOIN notify to its local clients and locally connected servers
6477 if needed. Normal server will send JOIN notify to its local client
6478 on same channel when received this packet. Added also corresponding
6479 sending function silc_server_send_new_channel_user to sent the
6482 * Added boolean route argument to send_notif_to_channel and
6483 packet_send_to_channel functions to attempt to route the packet
6484 if it is TRUE and send only locally if it is FALSE.
6486 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6488 * silc_server_replace_id now broadcasts the received replace ID
6489 packet if it is not broadcast packet already. The router must
6490 broadcast to inform other routers about changed ID.
6492 * Added backpointer to server's router into SilcServer context in
6493 silcd/server_internal.h.
6495 * Fixed silc_server_packet_broadcast to send correct broadcast
6498 * The channel key is now distributed to the local client as soon
6499 as it is received from the router (in router environment) so that
6500 no other packet may be sent for the channel until client has
6503 * silc_server_remove_channel_user now broadcasts the received
6504 Remove Channel User packet if it is not broadcast packet already.
6505 The router must broadcast to inform other routers about removed
6508 * Added users field into SilcPacketContext that is a reference count
6509 of the context. One can increase the reference count by calling
6510 silc_packet_context_dup which is now changed to just increase the
6511 reference count instead of duplicating the data. The reference
6512 count is decresed by calling silc_packet_context_free that will
6513 free the data after the reference count hits zero.
6515 For now on the packet context and everything allocated into it
6516 (including the raw packet from network) must be freed by calling
6517 the new silc_packet_context_free function. Added also new function
6518 silc_packet_context_alloc that must be used now to allocate the
6519 context. This also means that if a routine is asynchronous from
6520 silc_[client/server]_packet_parse_type the packet context must
6521 be duplicated by calling silc_packet_context_dup. Otherwise it
6522 gets free'd after silc_[client/server]_packet_parse_type returns.
6523 Also, one must remember that if packet is duplicated then its
6524 reference count must be decresed by calling the free function as
6525 many times as it was duplicated.
6527 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6528 from both client and server.
6530 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6532 * Made joining to a channel working in router environment.
6534 * Cleaned up JOIN command on server side and create function
6535 silc_server_command_join_channel internal routine to make the
6538 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6540 * Changed silc_command_pending list to SilcDList. Also, added
6541 `ident' field to SilcServerCommandPending structure to identify
6542 the reply and to call correct callback.
6544 Added silc_server_command_pending_check function to replace the
6545 corresnponding macro. The silc_command_pending list is not
6548 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6549 to set identifier to previously allocated Command Payload. It
6550 is used to set identifier for command when resending Command
6553 * Added silc_command_payload_encode_payload to encode Command
6554 Payload buffer from SilcCommandPayload structure.
6556 * Added silc_argument_payload_encode_payload to encode Argument
6557 payload buffer from SilcArgumentPayload structure.
6559 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6561 * Changed WHOIS command to support router connection on server side.
6562 The whois request is always sent to router unless the server is
6563 standalone server. After server has received the reply from the
6564 router will it send the reply to the client.
6566 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6567 broadcast received broadcast packet. The function is used only
6568 by router. The broadcast packet is always sent to the router's
6571 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6572 render given ID to printable string, for log files for example.
6574 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6576 * Made basic router to router connections working. At least they
6577 can now connect to each other but nothing really works the way
6578 they are supposed - yet.
6580 * Added new initiator token to RouterConnection configuration
6581 file in silcd/serverconfig.[ch]. It is used to tell whether we
6582 are the initiator to the remote router or whether we'll expect
6583 the other end to connect.
6585 * Moved registering of listener task to silc_server_init, hence
6586 the server starts listenning as soon as it is run, even if it
6587 does not have connections to other routers. Let's see how well
6590 * Changed default connection retry timeouts for more suitable in
6593 * Removed cipher and such arguments from silc_idlist_add_client
6594 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6595 Added new function silc_idlist_add_data to add the keys and stuff
6598 * Added SilcIDListData structure and added it to SilcClientEntry
6599 and SilcServerEntry as their first field in the structure. This
6600 way we can explicitly cast the ID entries to the SilcIDListData
6601 structure and get common data for the entries. In past, we had
6602 to first check what type of connection it is and then cast it to
6603 correct ID entry type. Now, we can directly cast the opaque
6604 pointer to the SilcIDListData (no matter what ID entry it actually
6605 is) and get the data needed.
6607 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6609 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6610 in some circumstances even if threre were timeout tasks, though not
6611 IO tasks, but tasks anyway. Now fixed.
6613 * Defined SilcServerConnection structure to hold connection specific
6614 stuff about directly connected servers and routers. The definition
6615 is currently in silcd/server_internal.h. I thought about having
6616 a bit more important role fro this struct but for now it is used
6617 only when connecting to other server (or router actually).
6619 * Added connecting retry support in server when connecting to
6620 router(s). The retry feature implement exponential backoff
6621 algorithm. Also, added SilcServerParams structure to hold default
6622 parameters for server. For now, it include these retry settings
6623 and are hard coded. After server is moded to be as Silc Server
6624 Library this structure will be more important.
6626 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6628 * Changed client librarys channel->clients table to SilcList and
6629 changed code accordingly.
6631 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6633 * Changed client's channel table to SilcList and changed code
6634 accordingly. Also changed SilcChannelClientEntry to include back-
6635 pointer to the channel so that client entry can use that structure
6636 as list as well and we have fast cross-reference to the channel.
6637 This change dramatically decreased the complexity of channel
6638 handling with client entry and vice versa (removed one extra
6639 loop when searching for channel entry from many functions).
6641 * Changed server->sim from table to SilcDList and changed code
6644 * NAMES command can now be used from user interface. It will show
6645 the user list on the channel, neatly.
6647 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6648 Code now saves realname of the user if it becomes available.
6650 * Renamed configure.in to configure.in.pre and made ./prepare
6651 script to automatically add correct version string to
6652 configure.in which it creates from configure.in.pre.
6654 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6656 * NAMES command reply now shows users mode with the nickname when
6659 * Moved silc_client_ch[u]mode[_char] functions from
6660 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6661 place sucks, they are utility functions and should be in some
6664 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6666 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6669 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6673 * Added TRQ (efficient deque and list library) into lib/trq. This is
6674 a very good list library that is currently used in the SILC. Defined
6675 SilcList API over the library because I didn't like the API very
6676 much. See lib/trq/silclist.h for the API and examples of how to
6677 use the API. Fixed various places in the code to use the new
6678 SilcList API. The SilcList is meant for lists that has a structure
6679 already defined as a list. It is not suitable to add just some
6680 context to the list (in TRQ, the context is the list actually).
6682 So, I defined SilcDList that can be used for the purpose where
6683 predefined list structure does not exit. This can be used as
6684 such list. Now some context just can be added to the SilcDList.
6685 Currently this list is not used in the SILC just yet, though there
6686 are a lot places where this can replace dynamically allocated
6687 tables and I will fix these places, later, to use SilcDList.
6688 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6689 and use TRQ internally).
6691 Also fixed some annoying warning messages that the original TRQ
6692 code generated. Also minor changes to TRQ's Makefile.in.
6694 * Added support for querying by Client ID to both WHOIS and
6695 IDENTIFY commands into server, as required by the protocol.
6697 * Removed method function pointers from SilcBuffer structure. They
6698 weren't used to anything and just increased the context size for
6699 no good reason. This change also made silc_buffer_alloc and
6700 silc_buffer_free functions inline functions.
6702 * Disabled command flooding detection support until it's fixed so
6703 that it accepts commands in but does not execute them more than once
6706 * Added silc_net_localhost(), to return local hostname, into
6707 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6708 that must be initialized before calling silc_client_init.
6710 * Added new function: silc_server_send_notify_on_channels to send
6711 notify messages to all channels client has joined. It is assured
6712 that the message is sent only once per client.
6714 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6715 lib/silcutil/silcutil.[ch] as silc_format function. The new
6716 function is generic and is used by server as well, not only by
6717 the logging routines.
6719 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6720 the provided version string was not acceptable. Added new function:
6721 silc_ske_check_version into lib/silcske/silcske.h. The function
6722 must be implemented by the application (client or server) and it
6723 does not reside in the SKE library. The function checks the version
6724 string remote end sent.
6726 * Added back pointers (to opaque context and to SilcSocketConnection)
6727 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6729 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6730 duplicate packet context structure.
6732 * Changed `notify' client operation to send same arguments as client
6733 receives from server except for ID's. ID's are mapped to correct
6734 ID entry and that is returned. Also, if channel entry is not sent
6735 by server but the notify is for channel the channel entry is sent
6736 to application (otherwise application doesn't know that it is for
6737 channel (library gets it from packet's Destination ID)).
6739 * Added silc_client_remove_from_channels into client library to
6740 remove a client from all channels it has joined to. Used when
6741 received SIGNOFF notify from server. Added also new function
6742 silc_client_replace_from_channels to replace old ID entry with
6743 new ID entry on all channels. Used when received NICK_CHANGE
6746 * Fixed ID Cache list handling in silc_idlist_get_client in
6747 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6748 to get (or query) client by ID.
6750 * Updated TODO list.
6752 * Added connection authentication status message defined by the
6753 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6754 support for these into the code in client and server side.
6756 * Added generic function silc_client_send_command to send any command
6757 with variable argument list. Application should use this function
6758 to send commands if the command functions provided by the library
6759 does not suite for the application's user interface needs.
6761 * Added new `failure' client operation. Application is notified about
6762 received failure packet if client is executing a protocol. In this
6763 case the protocol's execution has failed.
6765 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6766 is required by the protocol.
6768 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6769 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6772 * Added status flag to SilcSKE object to indicate realtime status
6773 of the SKE protocol.
6775 * Application receives now exactly same command reply arguments as
6776 the library receives from server. However, if ID is received the
6777 corresponding ID entry is returned to the application (eg. Client
6778 ID is mapped to correct SilcClientEntry entry and that is returned).
6779 Changed command_reply client operation due to this change.
6781 * Changed all ID's in commands and in command replys as ID Payloads.
6782 Change affected both client and server side codes.
6784 All ID's sent in SILC network (with execption of ID's in SILC
6785 Packet header) are sent in ID Payload to support variable length
6788 * Server now notifies nick changes and notifies all clients on
6789 the channels about the new nickname (about the new Client ID,
6792 * Implemented CMODE command to change channel modes. Supports all
6793 channel modes defined by the protocol specs except ban and invite
6794 lists. (Also, private channel key mode is supported but support for
6795 setting private channel key in client is missing, thus, this mode
6796 has no effect on client side (except that server requires that the
6797 client uses private channel key and normal channel traffic does not
6800 Also, invite mode works per se, but INVITE command does not work
6801 yet correctly, so you can set channel as invite only channel but
6802 inviting clients to the channel does not work (it is yet to be
6803 thought what's the best way to do it).
6805 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6806 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6807 Implemented CUMODE command to change user's mode on the channel.
6808 Supports all modes defined by the protocol specs.
6810 * Added NAMES command reply to return users modes on the channel.
6812 * Removed unnecessary and slow ciphers from lib/silccrypt.
6814 * Set SO_KEEPALIVE option to connection sockets by default.
6816 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6818 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6819 redefined the Notify Payload into protocol specs.
6821 * Added silc_id_payload_parse_id to get ID directly from raw
6824 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6826 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6827 accept searching by Client ID as well.
6829 * Added support for LEAVE and SIGNOFF notify types in client library.
6831 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6832 to parse ID Payload from raw data.
6834 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6836 * Added flags parameter into silc_ske_assemble_security_properties
6837 function in lib/silcske/silcske.[ch].
6839 * Changed notify client operation to fit better for notify messages
6840 sent by server. The notify payload received from server is now
6841 passed to the application (after parsing it to SilcNotifyPayload).
6842 It is application's responsibility to retrieve the arguments
6843 from the payload and show the message the way it wants. The message
6844 sent by server is implementation specific.
6846 * Changed public keys to comply with the protocol specification.
6847 Old public keys are not supported anymore and are not compatible.
6849 * Removed nickname from Channel Payload as the latest draft removed
6850 it. The client must resolve the nickname from the NAMES command
6851 reply received when it joined the channel.
6853 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6855 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6857 * Fixed some errors in protocol specification drafts.
6859 * Created lib/silccore/silcnotify.c to implement Notify Payload
6860 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6861 generic payloads described by protocol specifications. The file
6862 includes implementations for ID Payload and Argument Payload.
6864 * Changed Command Payload implementation to use the new Argument
6865 Payload. Changed command_xxxx_payload to command_payload_xxxx
6866 to comply with SILC coding conventions.
6868 * Added suppport for Argument Payload handling in Notify Payload
6869 implementation as protocol requires it. Added the new support
6870 into server and client lib as well.
6872 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6874 * Added support for multiple nicknames on same channel. [n] is
6875 added locally to the nickname if there are more than one same
6876 nicknames on the channel.
6878 * Server now sends all nicknames that matched WHOIS request.
6879 Client also shows the list received from server.
6881 * Added TOPIC command to client side. User can now set and show
6882 current topic on channel.
6884 * Added MOTD command to client and server. Also, server sends the
6885 motd when client connects to the server.
6887 * Changed version strings to comply ISO 8601.
6889 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6891 * Fixed protocol error handling in client library. It should now
6892 cope even if the SKE fails for some reason.
6894 * Made new protocol specification drafts for submitting to IETF.
6896 * Implemented TOPIC command to server in silcd/command.c.
6898 * Added two new notify types into lib/silccore/silcnotify.h:
6899 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6900 notify nickname change and topic setting/change on a channel.
6902 * API change of command_reply operation in client library. The
6903 application gets now the status type received from server as well.
6905 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6907 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6909 * Cras fixed and optimized the packet handling even further and
6910 it should work now. Minor change to the prototype of function
6911 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6913 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6915 * Added new function into lib/silcutil/silcschedule.[ch]:
6916 silc_schedule_with_fd to select() a specified fd. The function
6917 returns after timeout expires or data arrives or goes. The
6918 function is used by packet routines to wait that all data is
6919 received from network.
6921 * Fixed data reading from network in lib/silccore/silcpacket.c.
6922 The code now assures that all data is read from the fd and then
6923 continues packet processing. This was a bug fix since the code
6924 used to drop some data in some circumstances.
6926 * Added new function into lib/silcclient/client.[ch]:
6927 silc_client_start_key_exchange to start key exchange after
6928 connection has been established to server. The code internally
6929 now uses this funtion but its main purpose was to provide it
6930 for applications that perform their own connecting. After
6931 application has created a connection it merely calls this
6932 function to start the key exchange between client and server.
6933 The library takes care of everything else after that.
6935 Updated also lib/silcclient/README to explain the usage of
6938 * Do not send to application information that connection has
6939 been established. Application gets notified it by connect
6942 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6944 * Applied cras's patch to add silc_schedule_one function. The
6945 function runs scheduler once and returns.
6947 * Fixed the scheduler after cras messed it up. The timeout
6948 handling works now as it's supposed to work.
6950 * Added into lib/silccore/ silcnotify.h to include notify
6951 message types support. Changed silc_server_send_notify*
6952 functions, in server.[ch], to support those new notify types.
6953 Added the support for the notify types into client library,
6954 as well. Added new notify client operation into ops.h in
6957 * Changed silc_server_packet_send_to_channel to send normal
6958 packets instead of just channel message packets. The function
6959 is now used to send the notify packets to channels. It is not
6960 used to send channel message packets anymore, as server never
6963 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6964 va_arg()s as it seems to require it nowadays. I guess, if SILC
6965 is compiled with older va_arg() the new code should work anyway.
6967 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6969 * Splitted core library. Core library (lib/silccore) includes
6970 now only SILC protocol specific core (and common) components.
6971 Created new utility library (lib/silcutil) that includes more
6972 generic purpose stuff. The stuff for util library was taken
6973 from the old core library. This was minor and easy split.
6975 * Created SILC Client Library (lib/silcclient) that includes
6976 implementation of the SILC client without user interface. This
6977 was major move from silc/ directory. The code has been changed
6978 so that it is transparent towards the user interface. The
6979 silc/ directory includes now the same user interface as before
6980 and it uses the new client library. Read lib/silcclient/README.
6981 Basicly, the client library performs everything else related
6982 to SILC except user interface handling. Also, configuration
6983 files are considered to be part of user interface and library
6984 does not handle them.
6986 This change also changed a lot of structures, function naming etc.
6987 Most important change was that SilcClientWindow object was
6988 renamed to SilcClientConnection in the client library. Created
6989 also new file lib/silcclient/ops.h. Also added new files
6990 silc/local_command.[ch] and silc/client_ops.[ch].
6992 All these changes were made to make it easier for user interface
6993 designers to create what ever user interface for the SILC client
6996 It is also expected that the server will be moved to lib
6997 directory as well and SILC Server Library will be created;
6998 sometimes in the future.
7000 * Removed Local commands from lib/silccore/silccommand.h as
7001 they are application specific and new client library does not
7002 handle any of those anymore.
7004 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7005 old client implementation in silc/.
7007 * Added support for callback functions in SILC_LOG_* macros.
7008 Application can now set its own callbacks that will be called
7009 instead of using the default functions that will always print
7010 the debug messages to stderr (or stdout). Also, debugging can
7011 now be disabled by setting silc_debug to FALSE and re-enabled by
7012 setting it to TRUE. Note, that logging will still work even
7013 if debugging is disabled.
7015 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7016 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7017 silc_log_reset_debug_callbacks.
7019 * To enable debugging in silc client one must give now -d
7020 option on command line.
7022 * Changed silc_schedule_init to automatically allocate task queues
7023 if they are not allocated before calling it.
7025 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7027 * Added GMP 3.1 into math library.
7029 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7031 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7032 a channel in SILC network. The packet is used by servers and
7033 routers to notify other routers that user has left a channel.
7034 This little feature was missing until now. Added the feature
7035 to protocol specification as well.
7037 Added functions: silc_server_send_remove_channel_user and
7038 silc_server_remove_channel_user into server.[ch].
7040 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7041 lib/silccore/silcpacket.h. However, they are not implemented
7044 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7046 * Fixed joining to a channel and sending channel messages
7047 between server and router. The channel message sending should
7048 now work inside a cell.
7050 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7052 * Fixed the private message sending between server and router.
7053 The private message sending should now work inside a cell.
7055 * Added silc_server_replace_id into server.[ch] to replace
7056 existing ID in the SILC network.
7058 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7059 and silc_idlist_replace_server_id into idlist.[ch] in server.
7061 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7063 * Fixed the server to server connections. Server can again now
7064 connect to router. Router to router connections probably does
7067 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7069 * Added dynamic protocol registering support. Now protocols can
7070 registered and unregistered on the fly. Patch by cras.
7072 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7074 * Added lib/contrib directory to hold routines that some platforms
7075 don't have but are needed by SILC.
7077 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7078 into lin/contrib to provide getopt() and getopt_long() for
7079 those who don't have it.
7081 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7083 * Added AWAY command to client. When away message is set and
7084 client receives a private message packet the client automatically
7085 replies to the sender with the away message.
7087 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7088 bug seemed to be the cause of recent problems when compiling
7091 * Added version detection support to SKE protocol specification
7092 and added the new changes to the SKE implementation as well.
7093 There were other minor changes in the SKE protocol as well.
7095 Many changes in lib/silcske/silcske.[ch] and in
7096 lib/silcske/payload.[ch].
7098 * Added ^U functionality, clear input line. Patch from cras.
7100 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7102 * Mainly small bugfixes on core library. Fixed some debugging
7103 logging and buffer overflow in silclog.c.
7105 * Updated config.sub and config.guess on the distribution tree.
7107 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7109 * Added command lagging support in server. Client may execute
7110 commands now only once in two seconds.
7112 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7114 * Optimized packet reception. MAC computation and checking is now
7115 also more optimized. A lot previously duplicated code is now
7116 used as generic by both client and server.
7118 * Fixed key pair generation in clientutil.c
7120 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7122 * Added into lib/silccore/silcbufutil.[ch] new function;
7123 silc_buffer_realloc.
7125 * Moved generic packet sending/encryption functions to
7126 lib/silccore/silcpacket.[ch] from client and server. Some
7127 rewriting of the functions.
7129 * Moved all generic packet reception/decryption functions to
7130 lib/silccore/silcpacket.[ch] from client and server. The
7131 packet processing is now much cleaner in both client and server.
7132 These were major changes in both client and server.
7134 * Created many common functions in server to do packet sending.
7135 Previously code were duplicated a lot, this has been removed
7138 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7140 * Rewrote major parts of the ID cache system. Don't know
7141 whether it is better now or not but at least the API is more
7144 * Major rewrite on ID cache stuff on client because of the ID
7145 cache API changes. Added idlist.c to client.
7147 * Also major rewrite on ID cache stuff on server as well.
7148 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7149 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7150 in hand, instead they are all put into the ID cache system now.
7151 All server_idlist_* routines uses ID cache now instead of
7152 traversing its own lists (those lists does not exist anymore).
7153 SilcIDList though still exists. Also, SilcXXXEntry's are
7156 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7158 * Finally made the SKE implementation compliant to the protocol
7159 specification. All mp integers are now binary encoded as
7160 opposed being HEX encoded.
7162 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7165 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7166 functions: silc_[encode/decode]_pem. Also added function
7167 silc_encode_pem_file to PEM encode with newlines ('\n') for
7170 * SILC public keys are now encoded either PEM or binary. Same
7171 option is for private keys as well. By default private keys
7172 are binary encoded and public keys PEM encoded. Silly HEX
7173 encoding were removed.
7175 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7176 function to create fingerprints.
7178 * Fixed a bug in SHA1; does not change the original data anymore.
7180 * Partly implemented INFO command on client and server side.
7181 Fixed CLEAR command. Changes to SERVER command; show current
7182 server(s) when giving command without arguments. Added
7183 VERSION command to client.
7185 * Added check to server that unregistered connections cannot
7186 execute commands (unless it is specificly allowed).
7188 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7190 * Fixed screen refresh.
7192 * Fixed channel joining bug from client. On some circumstances
7193 client tried to join to a channel it had already joined.
7195 * Added public key verification process into client's protocol.c.
7196 The client now verifies the public key from user and saves
7197 it into ~./silc/serverkeys/ directory.
7199 Added into: clientutil.[ch]: silc_client_verify_server_key.
7201 * Changed SKE protocol's silc_ske_initiator_finish function
7202 to accept callback function that verifies the received public
7203 key. Removed old silc_ske_verify_public_key function.
7205 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7207 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7208 silc_pkcs_private_key[_data]_set.
7210 * Made the password and public authentication more cleaner in
7211 server's protocol.c.
7213 * Removed historic and obsolete protocol `channel_auth' from
7214 both client and server.
7216 * Removed wrong way of sending command status messages from
7217 server to client in server's command.c. The old way violated
7218 protocol specification.
7220 Changes to silccore/silccommand.[ch]: removed
7221 silc_command_encode_status_payload -> not needed anymore,
7222 changed silc_command_encode_payload_va to accept extra
7223 argument on variable argument list. The argument type must
7224 now be provided to the function. Also, added new function:
7225 silc_command_encode_reply_payload_va which is same as
7226 normal command_encode_payload_va except command status type
7227 is provided as extra argument.
7229 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7231 * Added ~./silc directory handling. The directory includes the
7232 public and private keys for the client.
7234 Added silc_client_check_silc_dir, silc_client_create_identifier
7235 and silc_client_load_keys.
7237 * Implemented SILC protocol compliant public key. Added public
7238 and private key saving to and loading from files.
7240 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7241 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7242 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7243 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7244 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7246 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7247 silc_pkcs_load_[public/private]_key.
7249 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7251 * Added silc_server_get_route (route.[ch]) to get connection
7252 data for the fastest route for given ID.
7254 * Implemented INVITE command on client and server. The command
7255 were re-defined in the SILC Protocol Specification and the
7256 implementation now complies with the specification.
7258 * Implemented PING command on client and server.
7260 * Implemented NAMES command on client and server. The server side
7261 supports currently only normal server not router server yet.
7262 Some changes to NAMES definition in SILC protocol specification.
7264 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7266 * Implemented LEAVE command on client and server.
7268 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7269 again. This change was made to the protocol as well. Server
7270 should not violate the protocol specification anymore.
7272 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7274 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7275 was tested. SOCKS4 was not but should work anyway.
