21 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
22 to avoid collisions with other libraries using same type names
25 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
27 * Added `prefer_ipv6' argument to the functions
28 silc_net_gethostbyname[_async]. If it is TRUE it will return
29 IPv6 address over IPv4. If FALSE IPv4 address is returned
30 even if IPv6 address was found. Affected files
31 lib/silcutil/silcnet.[ch].
33 * Added support silc_net_create_connection[_async] to fallback
34 to IPv4 address if IPv6 address could not be used (like if

47 application does not need to define them. Affected file
48 includes/silcincludes.h.
50 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
51 old name went against naming convention. Applications now
52 include "silcclient.h" instead of "clientlibincludes.h".
53 Removed includes/clientlibincludes.h, it is redundant now.
55 * Renamed includes/version.h to silcversion.h.
57 * Added really preliminary support for OS/2 into the util
58 library. Only thread & mutex API is implemented, others
59 are still to be implemented. Created the lib/silcutil/os2/
60 directory. Created also file includes/silcos2.h.
62 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

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

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

197 whether given configuration value has been given already.
199 Affected files silcd/serverconfig.[c], server.[c].
201 * Splitted the doc/example_silcd.conf.in. Separated the crypto
202 algorithm parts and created new file silcalgs.conf, that
203 is now included from the example_silcd.conf.in.
205 * Optimized the silc_server_connect_to_router_second to take
206 the connection configuration object from the SilcServerConnection
207 object instead of finding it during the connecting phase.
208 Added the configuration object to SilcServerConnection struct.
209 Affected files silcd/server_internal.h, server.c.

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

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

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

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

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

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

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

562 the client becoming valid after the server becomes back
563 online. Affected file silcd/server_util.c.
565 * Added `sock_error' field into the SilcSocketConnection
566 context. When error occurs during socket operation (read
567 or write) the error is saved. Added also new function
568 silc_socket_get_error to return human readable socket error
569 message. Affected files are lib/silcutil/silcsockconn.[ch],
570 lib/silcutil/unix/silcunixsockconn.c, and
571 lib/silcutil/win32/silcwin32sockconn.c.
573 * The server now prints the socket error message in the
574 signoff for client. Affected file silcd/server.c.
576 * Fixed the `created' channel information sending from router
577 to server in JOIN command. Checks now whether the channel
578 really was created or not and set it according that.
580 Fixed the JOIN command to use the client entry's current
581 ID during the joining procedure instead of the one it sent
582 in the command (it is checked though), since it can change
583 between the packet processing and command processing, and
584 would just case unnecessary pain in the client end. Affected
585 file silcd/command.c.
587 * Fixed a channel key payload sending to use correct channel
588 ID when the server was forced to change the channel's ID by
589 router. Router sent the key payload with the old Channel ID.
590 Affected file silcd/packet_receive.c.
592 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
594 * Call silc_server_save_channel_key only if the key payload
595 was provided in the JOIN command's command reply. Affected
596 file silcd/command_reply.c.
598 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
600 * Fixed silc_mp_sizeinbase to return the value correctly with
601 MPI. Affected file lib/silcmath/mp_mpi.c.
603 * Fixed the stop_server signal to correctly stop the scheduler
604 and gracefully stop the server when SIGTERM or SIGINT signals
605 are received. Affected file silcd/silcd.c.
607 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
609 * Simple handling of TERM and HUP signals. Also added some log
610 flushing call around. Affected file is
613 * Fixed small bugs in silclog.c. Now buffering output will take
614 effect after 10 seconds since startup: This will ensure that
615 no important startup messages are lost. Also output redirection
616 will preserve original format ([Date] [Type] message).
617 Affected file is lib/silcutil/silclog.c.
619 * Added two options to the config file, in the logging section:
620 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
621 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
623 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
625 * Do not print the warning about log files not being initialized
626 more than once to avoid excess logging. Affected file is
627 lib/silcutil/silclog.c.
629 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
630 the SIM copying in make install in Makefile.am.pre.
632 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
634 * Rewritten silclog APIs. Globally interesting changes follows:
635 silc_log_set_files() changed to silc_log_set_file().
636 silc_log_set_callbacks() changed to silc_log_set_callback().
637 ROBOdoc documented silclog header file.
638 SilcLogCb now returns bool to wether inihibit the default
639 handler or not (to keep the old behaviour return always TRUE).
640 The new APIs should also fix the problem of the
641 silcd_error.log file that was written in the current directory.
644 Log files streams will remain opened after silc_log_set_file()
645 call, means less CPU usage notably on high traffic servers.
646 File streams are now full buffered, and flushed to the disk
647 every 5 minutes, lesses HD activity and CPU usage.
648 Messages can be redirected, allowing admins to configure
649 one single logfile for all server messages.
650 the silc_log_quick global variable to activate fast-logging.
651 Affected files lib/silcutil/silclog.[ch]
653 * Changed some code to conform new silclog APIs. Affected
654 files are doc/example_silcd.conf.in, silcd/server.c
655 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
658 * Fixed a memory leak that could occur in some situations.
659 Affected file silcd/serverconfig.c.
661 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
663 * Added the silc_client_del_client to remove the client from
664 all channels as well. Affected file lib/silcclient/idlist.c.
666 * Fixed the client library to correctly remove the client
667 from all channels when the client entry is being destroyed.
668 Affected file lib/silcclient/client_notify.c, command.c.
670 * Added auto-nicking support to the client library. If the
671 applicatio now sets client->nickname it will be sent to the
672 server after connecting by the library. This way for example
673 SILCNICK (or IRCNICK) environment variables will have effect
674 and always change the nickname automatically to whatever
675 it is wanted. Affected file lib/silcclient/client.[ch].
677 * Renamed silc_server_command_bad_chars to the
678 silc_server_name_bad_chars and moved it to the
679 silcd/server_util.[ch]. Added also new function
680 silc_server_name_modify_bad to return nickname that
681 includes bad characters as new nickname without those
682 bad characters. This check and modify is now used in
683 silc_server_new_client when the username is initially set
684 as nickname, so it must be checked to be valid nickname.
685 Affected file silcd/packet_receive.c.
687 * The nickname length is now taken from the packet for real
688 and not trusted to strlen() since it clearly can return
689 wrong length for nickname including bad characters. This
690 also applies to channel names. Affected file silcd/command.c.
692 * Removed the lib/silcsilm/modules directory. Modules are now
693 compiled into the lib/silcsim. Fixed the copying of the
694 modules to follow symbolic links in Makefile.am.pre.
696 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
698 * Fixed silc_string_regexify list creation. Fixes bugs with
699 BAN and INVITE commands in server. The affected file is
700 lib/silcutil/unix/silcunixutil.c.
702 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
704 * Removed the command destructor entirely from the server's
705 command and command reply routines. It is not needed, and
706 its usage was buggy and caused crashes. Affected files are
707 silcd/command[_reply].[ch].
709 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
711 * Cancel protocol and NULL sock->protocol if timeout
712 occurred during protocol. Affected file silcd/server.c.
714 * Cancel protocol timeouts always before calling the final
715 callback, to assure that after final callback is called
716 no other state will be called for the protocol anymore.
717 Affected file silcd/protocol.c.
719 * Print error log if incoming connection configuration could
720 not be found. Affected file silcd/server.c.
722 * Fixed JOIN command to correctly save the founder mode
723 to the client on normal SILC server, when the channel
724 was created by the router. Affected file silcd/command.c.
726 * Fixed LIST command (hopefully) to send correct reply
727 packets. Affected file silcd/command.c.
729 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
731 * The silc_packet_receive_process now returns FALSE if the
732 read data was invalid packet, and TRUE if it was ok.
734 The server now checks that if unauthenticated connection
735 sends data and its processing fails the server will close
736 the connection since it could be a malicious flooder.
738 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
740 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
742 * Make sure the warning about error opening a log file is
743 printed only once and not everytime it fails (produces
744 too much useless log). Affected file lib/silcutil/silclog.c.
746 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
748 * Made the silc_server_daemonise() function more readable.
749 Affected file silcd/server.c.
751 * Pid file is now optional, the user may comment it out from
752 the config file. Removed define SILC_SERVER_PID_FILE, we
753 don't need a default any longer. Affected file
754 configure.in.pre, lib/Makefile.am.pre.
756 * Make some use of the pid file. The server now dies at startup
757 if it detects a valid pid file on his path. The server would
758 die anyway in this circumstance, because of the bind() failure.
759 Affected file silcd/silcd.c.
761 * No longer compiling lib/dotconf.
763 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
765 * Fixed JOIN command parsing not to crash. Affected file
766 lib/silcclient/command.c.
768 * Fied the NICK_CHANGE notify to add the new client entry
769 even it is resolved. This removes an <[unknown]> nick
770 thingy bug in the client. Affected file is
771 lib/silcclient/client_notify.c.
773 * Do not try to allocate 0 bytes (efence does not like it)
774 in lib/silccore/silccomand.c when encoding payload.
776 * Do not take IRCNICK as nickname in Irssi SILC client since
777 it is not possible to set nickname before hand connecting
778 the server (TODO has an entry about adding auto-nicking
781 * Changed the silc_server_command_pending to check whether
782 there already exists an pending entry with the specified
783 command, command identifier and pending callback. This is
784 to fix IDENTIFY and WHOIS related crashes that may register
785 multiple pending commands with same identifier. Affected
786 file silcd/command.c.
788 * Fixed the server to reconnect to the router even if it
789 was already reconnecting and EOF was received. This to
790 fix a possibility that the server wouldn't ever try to
791 auto-reconnect to the router. Affected file silcd/server.c.
793 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
795 * Fixed the server's password authentication to use the
796 length of the locally saved password, and not the one
797 sent in the packet. Affected file silcd/protocol.c.
799 * Fixed same password authentication problem in the
800 Authentication Payload handling routines in
801 lib/silccore/silcauth.c.
803 * Yet another password authentication problem fixed with
804 channel password handling in silcd/command.c.
806 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
808 * If first character of string in silc_parse_userfqdn is '@'
809 then do not parse it. Affected file is
810 lib/silcutil/silcutil.c.
812 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
814 * Fixed minor bug in IDENTIFY command reply sending, which
815 caused various weird problems during JOIN when it was
816 resolving names for users. Affected file silcd/command.c.
818 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
820 * Fixed the IDENTIFY command reply sending to chech better valid
821 clients. It was possible to send incomplete list of replies.
822 Affected file silcd/command.c.
824 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
826 * Added silc_client_command[s]_[un]register functions now to
827 dynamically register the commands in client library. Removed
828 the static table of commands. This allows the client library
829 to call commands without causing the application to know about
830 what commands library has called.
832 Removed the INFO command reply kludge to detect when the command
833 was called by library. Now library use its own command reply
834 function for INFO command.
836 Added function silc_client_command_call to call a command.
837 Application can use it to call command, not access the structure
840 Now all commands that are sent by the client library (not
841 explicitly sent by application) use own command reply functions.
843 Affected files around lib/silcclient/ and in
844 irssi/src/silc/core/.
846 * Fixed the WHOIS command reply sending to chech better valid
847 clients. It was possible to send incomplete list of replies.
849 Fixed the WHOIS and IDENTIFY to send the request to router
850 if normal server did not do it and did not find any results.
852 Affected file silcd/command.c.
854 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
856 * Moved the internal data from SilcClient context into its
857 own file, not accesible to application. Affected files
858 lib/silcclient/client.h and lib/silcclient/client_internal.h,
859 and other files in client library.
861 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
863 * Added doc/examples installation target in Makefile.am.pre.
866 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
868 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
869 commands the found client entry will be removed from the
870 cache, after notifying application about the error. Affected
871 file lib/silcclient/command_reply.c.
873 * Changed the /MSG to check for exact nickname user gave, and
874 not let `nick' match `nick@host' if it is only one found. Now,
875 user must type the exact nickname (like nick@host2) even if
876 there are no more than one same nicks found. This is to avoid
877 a possibility of sending nickname to wrong nickname since
878 `nick' could match `nick@host'. Affected file is
879 irssi/src/core/silc-servers.c.
881 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
883 * Do not print "you are now server operator" or similar when
884 giving /away command. Affected files are
885 irssi/src/silc/core/client_ops.c, silc-servers.h.
887 * Made the silc_server_command_pending_error_check to send
888 the same command reply payload it received back to the
889 original sender of the command. This way all arguments
890 that was received by the server will be received by the
891 client too. Affected file silcd/command.c.
893 * Added the silc_idcache_add to return the created cache entry
894 to a pointer. Affected file lib/silccore/silcidcache.[ch].
896 * Add global clients to expire if they are not on any channel.
897 This is because normal server will never know if they signoff
898 if they are not on any channel. The cache expiry will take
899 case of these entries. This is done by normal servers only.
900 The affected files are silcd/command_reply.c,
901 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
903 * If server receives invalid ID notification for WHOIS or
904 IDENTIFY and the ID exists in the lists, it is removed.
905 Affected file silcd/command_reply.c.
907 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
908 in client then client entry that it matches is searched and
909 the nickname is printed on the screen for user. Affected
910 file irssi/src/silc/core/client_ops.c.
912 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
914 * Use cache entry expire time in the LIST command reply to
915 purge old entries from the cache after the LIST command
916 reply has been received. This way we don't have non-existent
917 entries in the cache for too long. Affected file is
918 silcd/command_reply.c.
920 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
922 * If we are normal server, and we've not resolved client info
923 in WHOIS or IDENTIFY from router, and it is global client,
924 we'll check whether it is on some channel. If it is not
925 then we cannot be sure about its validity and will resolve it
926 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
927 file silcd/command.c.
929 * Search channel by name (if possible) rather than by ID
930 in IDENTIFY command's command reply. Affected file is
931 silcd/command_reply.c.
933 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
935 * Distribute to the channel passphrase in CMODE_CHANGE notify.
936 Updated specs and implemented it. Affected file silcd/command.c,
937 silcd/packet_send.c and silcd/packet_receive.c.
939 * Implemented the <founder auth> payload handling in the JOIN
940 command. If provided all conditions for channel joining
941 except requirement to provide correct passphrase can be
942 overrided by the channel founder. Updated the protocol specs.
943 Affected file silcd/command.c.
945 Added support for founder auth in JOIN command in client
946 library. Fixed the parsing of the JOIN command now to support
947 all options as they should be. The affected file is
948 lib/silcclient/command.c.
950 * Optimized the WHOIS and IDENTIFY commands to send the request
951 to router only if it includes nicknames or other names. If
952 they include only IDs then check the local cache first before
953 routing. Affected file is silcd/command.c.
955 * Added channels topic announcements. Affected file is
956 silcd/packet_receive.c and silcd/server.c.
958 * Fixed the silc_server_send_notify_topic_set to really destine
959 the packet to channel. Affected file silcd/packet_send.c.
961 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
962 library. Affected file lib/silcclient/client_notify.c.
964 * Added UMODE announcements. Affected file silcd/server.c.
966 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
968 * Memory leak fixes in:
970 lib/silcutil/silcsockconn.c
971 lib/silcske/silcske.c
974 lib/silccrypt/silcpkcs.c
975 lib/silccore/silccommand.c
976 lib/silccore/silcidcache.c
981 * ROBOdoc documented the lib/silcske/groups.h file and a
982 bit changed the interface for better.
984 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
986 * Update the client entry context in the ID cache after
987 nick change. Affected file lib/silcclient/command.c.
988 Fixes the CUMODE command when regaining founder privileges,
989 and a little WHOIS problem.
991 * Fixed silc_net_gethostbyname to correctly call the
992 inet_ntop. Affected file lib/silcutil/silcnet.c.
994 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
996 * Added IPv6 support checking to the configure.in.pre, added
997 also --enable-ipv6 option to override the check. Affected
998 file configure.in.pre.
1000 * The silc_thread_create now calls the start function
1001 directly if threads support is not compiled in. Removes
1002 ugly #ifdef's from generic code. Affected files are
1003 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1005 * Added silc_net_gethostby[name/addr]_async to asynchronously
1006 resolve. Affected files are lib/silcutil/silcnet.[ch].
1008 * Added support for rendering IPv6 based server, client and
1009 channel IDs. Affected file lib/silcutil/silcutil.c.
1011 * Added support for creating IPv6 based server IDs. Affected
1012 file is silcd/serverid.c.
1014 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1016 * Added silc_net_gethostby[addr/name] into the
1017 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1018 routines. Added silc_net_is_ip[4/6]. Affected file is
1019 lib/silcutil/unix/silcunixnet.c. All routines that take
1020 address as argument now supports both IPv4 and IPv6 addresses.
1022 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1024 * Fixed LIST command reply sending in server. Affected file
1027 * Server now sends the kicker's client ID in the KICK notify
1028 to the kicked client. Affected file silcd/command.c.
1030 * The client library now parses the kickers client ID and
1031 UI displays it. Affected files lib/silcclient/client_notify.c
1032 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1034 * Made all payload parsing function prototypes consistent.
1035 They all take now const unsigned char * and uint32 pair as
1036 the payload data instead of SilcBuffer. Changes all around
1037 the source tree. Other unsigned char* -> const unsigned char*
1038 changes around the tree as well.
1040 * Optimized SFTP client and server packet sending not to
1041 allocate new buffer for each packet but to recycle the
1042 first allocated buffer. Affected files are
1043 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1045 * Optimized the SFTP client to use SilcList instead of
1046 SilcDList for requests, because it is faster. Affected file
1047 is lib/silcsftp/sftp_client.c.
1049 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1050 into lib/silccore/silcid.[ch].
1052 Renamed silcpayload.[ch] into silcargument.[ch].
1054 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1056 * If client entry is deleted with active key agreement
1057 session, abort the session.
1059 The silc_client_abort_key_agreement now calls the completion
1060 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1062 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1065 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1067 * Don't use __restrict in older GCC's. Affected file is
1068 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1070 * silc_net_localhost now attempts to reverse lookup the
1071 IP/hostname. Affected file lib/silcutil/silcnet.c.
1073 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1074 command. It can be used to gain founder privileges at
1075 the same time when joining the channel.
1077 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1078 kicker's client ID as well. Updated protocol specs.
1080 Defined that the server must send SILC_COMMAND_IDENTIFY
1081 command reply with error status to client who sent
1082 private message with invalid client ID.
1084 Updated the protocol specification.
1086 * Added silc_server_send_command_reply to send any
1087 command reply. Affected file silcd/packet_send.[ch].
1089 * Added silc_id_payload_encode_data to encode ID payload
1090 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1092 * The server now send IDENTIFY command reply with error
1093 status if client ID in private message is invalid. Affected
1094 file silcd/packet_receive.c.
1096 * Save the server key file with server's IP address in
1097 the filename instead of hostname. The affected file is
1098 irssi/src/silc/core/client_ops.c.
1100 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1102 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1105 * Added libtool support for compiling shared objects in
1106 lib/silcsim. Affected file configure.in.pre and
1107 lib/silcsim/Makefile.am. Original patch by cras.
1109 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1111 * Pid file configuration, and server's config file fixes
1112 patch by toma. Updated CREDITS file.
1114 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1116 * Fixed silc_client_channel_message to not try to decrypt
1117 the message twice if it resolved the destination client
1118 information. This could cause of dropping one channel
1119 message. Affected file lib/silcclient/client_channel.c.
1121 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1123 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1124 lib/silcclient/client.c. This function is used when the SILC
1125 Client is run under some other scheduler, or event loop or
1126 main loop. On GUI applications, for example this may be
1127 desired to used to run the client under the GUI application's
1128 main loop. Typically the GUI application would register an
1129 idle task that calls this function multiple times in a second
1130 to quickly process the SILC specific data.
1132 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1134 * Fixed silc_server_drop() for dropping the supplementary
1135 groups as well, this could cause a security hole on some
1138 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1140 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1143 * Write PID file after dropping privileges. Added -F option
1144 to run server on foreground. A patch by debolaz.
1145 Affected files silcd/server.c, silcd/silcd.c.
1147 * Fixed MOTD to return the MOTD file server name. Affected
1148 file silcd/command.c.
1150 * Added INFO command reply handling to the Irssi SILC Client.
1151 Affected file irssi/src/silc/core/client_ops.c.
1153 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1155 * Fixed the silc_idcache_list_* routines to really support
1156 the dynamic list. Fixes a crash. Affected file is
1157 lib/silccore/silcidcache.c.
1159 * Fixed the LIST command reply to really call LIST command's
1160 pending callbacks. Affected file silcd/command_reply.c.
1162 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1164 * Update conn->local_entry->nickname after giving NICK
1165 command. Affected file lib/silcclient/command.c.
1167 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1169 * Added the [pid] option to the silcd configuration file
1171 Affected files: serverconfig.[ch] and silcd.c
1173 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1175 * Save fingerprint in WHOIS command reply in server.
1176 Affected file silcd/command_reply.c.
1178 * Fixed NICK commands pending callback registration.
1179 Affected file lib/silcclient/command.c.
1181 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1183 * Use ++server->cmd_ident when sending commands in server,
1184 instead of random number. Affected file silcd/command.c.
1186 * Fixed GETKEY command reply to call actually GETKEY pending
1187 command callbacks. Affected file silcd/command_reply.c.
1189 * A bit stricter check for nicknames. Check for same nickname
1190 in NICK command also. Affected file silcd/command.c.
1192 * Do not call INFO command everytime client ID changes, only
1193 during first connecting. Affected file lib/silcclient/client.c.
1195 * Set the new nickname only after successful command reply for
1196 NICK command is returned by server. Affected file
1197 lib/silcclient/command.c.
1199 * Remove nicknames from nicklist during server_signoff notify.
1200 Should fix /NAMES bit more. The affected file is
1201 irssi/src/silc/core/silc-channels.c.
1203 * Added `fingerprint' field to the SilcIDListData in the
1204 silcd/idlist.h to hold the fingerprint of the client's
1207 Send the fingerprint of the client's public key in WHOIS
1210 Affected files silcd/command.c, and silcd/idlist.[ch].
1212 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1213 create fingerprint from given data.
1215 * Show the fingerprint of the client's public key in WHOIS.
1216 Affected files irssi/src/module-formats.[ch] and
1217 irssi/src/silc/core/client_ops.c.
1219 * Format the multiple same nicknames also during JOIN and
1220 NICK_CHANGE notifys. Affected file is
1221 lib/silcclient/client_notify.c.
1223 * Do not print error on screen for invalid private message
1224 payload since it can come if someone is sending private
1225 messages with wrong key. Affected file
1226 lib/silccore/silcprivate.c.
1228 * Fixed multiple concurrent /PING crash. Affected file
1229 lib/silcclient/command.c.
1231 * Changed the wrong ID encoding. All IP addresses must be
1232 in MSB first order in encoded format. They were encoded
1233 wrong and was in LSB format. Affected files are
1234 silcd/serverid.c, lib/silcutil/silcutil.c.
1236 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1238 * Call the `connect' client operation through the scheduler
1239 in case of error. Affected file lib/silcclient/client.c.
1241 * Call the `failure' client operation even if the error
1242 occurred locally during a protocol. Affected file is
1243 lib/silcclient/protocol.c.
1245 * Added support of sending LIST command to router from normal
1246 server. This way normal server can get list of all channels
1247 in the network too. Fixed the channel list sending in the
1248 server too. Affected files are silcd/command.c, and
1249 silcd/command_reply.[ch].
1251 * Added silc_server_update_channels_by_server and
1252 silc_server_remove_channels_by_server. They are used during
1253 disconnection of primary router and in backup router protocol.
1254 Affected file silcd/server_util.[ch], silcd/server.c and
1255 silcd/server_backup.c.
1257 * Fixed channel adding to global list in IDENTIFY command
1258 reply in server. Affected file silcd/command_reply.c.
1260 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1262 * If the incoming packet type is REKEY or REKEY_DONE process
1263 that packet always synchronously. Fixes yet another MAC
1264 failed error on slow (dialup) connections. Affected file
1265 lib/silcclient/client.c and silcd/server.c.
1267 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1269 * Call check_version SKE callback for initiator too. Affected
1270 file lib/silcske/silcske.c.
1272 * Implemented fix for security hole found in the SKE that was
1273 fixed in the specification few days back; the initiator's
1274 public key is now added to the HASH value computation.
1275 Added backwards support for the old way of doing it too, for
1276 old clients and old servers. Affected file is
1277 lib/silcske/silcske.c.
1279 * Enabled mutual authentication by default in SKE. If initiator
1280 is not providing mutual authentication the responder will
1281 force it. This will provide the proof of posession of the
1282 private key for responder. The affected files are
1283 lib/silcclient/protocol.c and silcd/protocol.c.
1285 * Do not cache anymore the server's public key during SKE.
1286 We do mutual authentication so the proof of posession of
1287 private key is done, and if the server is authenticated in
1288 conn auth protocol with public key we must have the public
1289 key already. Affected file silcd/protocol.c.
1291 * Added new global debug variable: silc_debug_hexdump. If
1292 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1293 file lib/silcutil/silclog.[ch].
1295 * Fixed compilation warning due to char * -> const char *.
1296 Affected files lib/silcutil/silcnet.h, and
1297 lib/silccore/silcauth.[ch].
1299 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1301 * Fixed CMODE command when new channel key was created. If
1302 the creation failed the old key was removed. Next time giving
1303 same command would crash the server since the old key was
1304 freed already. Affected file silcd/command.c.
1306 * Fixed the silc_server_announce_get_channels to not crash
1307 on reconnect. Affected file silcd/server.c.
1309 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1311 * Added silc_log_set_debug_string function to set a regex
1312 string to match for debug output. Only the function names,
1313 or filenames matching the given debug string is actually
1314 printed. This way it is possible to filter out those debug
1315 strings that user is not interested in.
1317 Fixed a bug in silc_string_regexify.
1319 Affected files lib/silcutil/silclog.[ch], and
1320 lib/silcutil/unix/silcunixutil.c.
1322 * Changed the -d options in both server and Irssi SILC client
1323 to take the debug string as argument. Affected files
1324 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1326 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1328 * Added silc_hash_babbleprint to create a Bubble Babble
1329 Encoded fingerprint. The encoding is developed by Antti
1330 Huima (draft-huima-babble-01.txt), and it creates human
1331 readable strings out of binary data. Affected file
1332 lib/silccrypt/silchash.[ch].
1334 * Print the babble print now in addition of fingerprint as well
1335 in Irssi SILC client. Affected files are
1336 irssi/src/fe-common/silc/module-formats.[ch],
1337 irssi/src/fe-common/silc/core/client_ops.c.
1339 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1341 * Fixed a security problem found in SKE. The initiator's
1342 public key too is now added to the HASH hash value creation
1343 which is signed by the responder to create the SIGN value.
1344 This will prevent anyone in the middle to lie to the responder
1345 about the initiator's public key. If this is done now, the
1346 man in the middle will get caught. Updated the protocol
1349 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1351 * Better installation directory handling. Configure module
1352 paths and other paths automatically to example_silc* files
1353 in doc/. A patch by toma.
1355 * Fixed compiler warning from MPI library, and from SILC RNG.
1358 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1359 It can be configured with ./configure. A patch by toma.
1361 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1363 * Find correct make to use in prepare-clean. A patch by
1364 toma. Affected file prepare-clean.
1366 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1368 * Added irssi variables use_auto_addr, auto_bind_ip,
1369 auto_bind_port and auto_public_ip.
1371 * Changed the interface for silc_client_send_key_agreement
1372 in lib/silcclient/silcapi.h
1376 irssi/src/silc/core/silc-core.c
1378 lib/silcclient/silcapi.h
1379 irssi/src/silc/core/silc-channels.c
1380 lib/silcclient/client_keyagr.c
1383 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1385 * Added silc_pkcs_public_key_compare to compare two
1386 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1388 * Check that the client who set the founder mode on the
1389 channel is the same client that is giving the founder
1390 mode to itself. It is done by comparing the saved public
1391 key (it is saved even in the authentication is passphrase).
1392 Affected file silcd/command.c.
1394 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1396 * Do not process packet for disconnected socket connection.
1397 Affected file lib/silccore/silcpacket.c.
1399 * Process the DISCONNECT packet through scheduler in the
1400 client library. Affected file lib/silcclient/client.c.
1402 * Fixed the silc_client_packet_parse to not to increase
1403 the packet sequence number if the conn->sock and the
1404 current socket connection is not same. This can happen
1405 for example during key agreement when the conn includes
1406 multiple socket connections (listeners). Affected file
1407 lib/silcclient/client.c.
1409 * The sender of the file transfer request now provides also
1410 the pointer (listener) for the key exchange protocol. If
1411 the listener cannot be created then it sends empty key
1412 agreement and lets the receiver provide the listener.
1414 Added `local_ip' and `local_port' arguments to the
1415 silc_client_file_send. If they are provided they are used,
1416 if not then it will attempt to find local IP address, if
1417 not found or bind fails then the remote client will provide
1420 Affected files are lib/silcclient/client_ftp.c and
1421 lib/silcclient/silcapi.h.
1423 * Extended the FILE SEND command to support defining the
1424 local IP and port for key exchange listener. They are
1425 optional. Affected file irssi/src/silc/core/silc-servers.c.
1427 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1429 * Defined to WHOIS command reply the sending of fingerprint
1430 of the client's public key (if the proof of posession of the
1431 corresponding private key is verified by the server).
1432 Updated to the protocol specification.
1434 * Added support of receiving the client's public key's
1435 fingerprint in command reply in client library. Affected
1436 file is lib/silcclient/command_reply.c, and
1437 lib/silcclient/idlist.[ch].
1439 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1441 * Do not send over 128 chars long nickname to the server
1442 in NICK command. Affected file lib/silcclient/command.c.
1444 * Do not send over 256 chars long channel names to the server
1445 in JOIN command. Affected file lib/silcclient/command.c.
1447 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1449 * Assure that silc_server_close_connection cannot be called
1450 twice for same socket context. Affected file is
1453 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1455 * Send error message to application if opening file for
1456 writing during file transfer fails. Affected file is
1457 lib/silcclient/client_ftp.c.
1459 Remove all file transfer sessions for a client that we're
1460 removing from ID cache.
1462 Affected file is lib/silcclient/client_ftp.c.
1464 * Fixed silc_net_addr2bin to return correct address. Affected
1465 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1467 * Fixed file transfer session removing on signoff notify.
1468 Affected file irssi/src/silc/core/silc-servers.c.
1470 * Added the SilcClientFileError to be returned in the monitor
1471 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1472 Affected file lib/silcclient/silcapi.h.
1474 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1476 * Fixed a crash in silc_client_ftp_free_sessions and
1477 silc_client_ftp_session_free_client. Affected file
1478 lib/silcclient/client_ftp.c.
1480 * Added `disabled' field in the SilcChannelEntry in the server
1481 to indicate if the server entry is disabled. Affected file
1482 silcd/idlist.h, silcd/command[_reply].c.
1484 * SILC server adds now /var/run/silcd.pid everytime it is
1485 started. Affected file silcd/silcd.c.
1487 * Added silc_server_packet_send_clients to send a packet to
1488 the provided table of client entries. Affected file
1489 silcd/packet_send.[ch].
1491 * Fixed a crash in client resolving in client_prvmsg.c in
1492 client library. Affected file lib/silcclient/client_prvmsg.c.
1494 * Do not actually remove the client directly from ID cache
1495 during SERVER_SIGNOFF, but invalidate it. This way we
1496 preserve the WHOWAS info for the client. Affected file
1497 silcd/server_util.c.
1499 * Fixed SERVER_SIGNOFF notify handling in the server. The
1500 server is now able to process incoming SERVER_SIGNOFF notify
1501 for a server that it doesn't even know about. It will remove
1502 the clients provided in the notify. Affected file
1503 silcd/packet_receive.c.
1505 * Check for partial packet in data queue after every packet that
1506 was found from the queue. Return and wait for more data if
1507 there is partial data in queue. Affected file is
1508 lib/silccore/silcpacket.c.
1510 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1512 * Added SilcClietFileError enum to indicate error in
1513 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1514 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1515 Affected files lib/silcclient/silcapi.h and
1516 lib/silcclient/client_ftp.c.
1518 * Check that newsize in silc_buffer_realloc is larger than
1519 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1521 * Added better monitor of file transfers. It now monitors
1522 key agreement protocol during the file transfer too. Added
1523 error reporting too. Affected files
1524 irssi/src/silc/core/silc-servers.c,
1525 irssi/src/fe-common/silc/module-formats.[ch].
1527 * Wrote a help file for FILE command.
1529 * Added silc_rng_global_get_byte_fast to get not-so-secure
1530 random data as fast as possible. Random data is read from
1531 /dev/urandom if available and from the SILC RNG if not
1532 available. It is used in padding generation. Affected file
1533 lib/silccrypt/silcrng.[ch].
1535 * All packets in client library are now processed synchronously.
1536 Optimized packet processing a lot. Affected file
1537 lib/silcclient/client.c.
1539 * All server connection packets are processing synchronously
1540 now in server, to optimize packet processing. Affected file
1543 * Include files are installed now only in Toolkit distribution
1544 if make install is given. Affected files: all Makefile.am's.
1546 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1548 * Assure that silc_client_notify_by_server_resolve does not
1549 resolve the client information multiple times. If it cannot
1550 be found by the first it cannot be found at all. Affected
1551 file lib/silcclient/client_notify.c.
1553 * Fixed WHOWAS command reply calling. Affected file
1554 lib/silcclient/command_reply.c.
1556 * Removed all references to silc_idlist_get_client from the
1557 Irssi SILC client since that call is internal call used by
1558 the library. The Irssi SILC client will use now client
1559 retrieval functions found in silcapi.h.
1561 * Fixed a bug in resolving nickname info before sending
1562 private message. It used freed memory. Affected file
1563 irssi/src/silc/core/silc-servers.c.
1565 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Assure my_channels statistics cannot go negative in server.
1568 Affected files silcd/server.c, silcd/server_util.c.
1570 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1574 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1576 * Win32 Toolkit changes. Affected files
1577 win32/silc.dsw, win32/libsilc/libsilc.def,
1578 win32/libsilcclient/libsilc.def,

1580 lib/sftp/sftp_fs_memory.c.
1582 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1584 * Added silc_net_localip to return local host's IP address.
1585 Affected file lib/silcutil/silcnet.[ch].
1587 * If key exchange or rekey protocol is active for a connection
1588 parse all packets syncronously since there might be packets
1589 in packet queue that we are not able to process without first
1590 processing packets before them. Affected file silcd/server,
1591 lib/silcclient/client.c.
1593 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1594 whether library should continue processing the packet.
1595 Affected file lib/silccore/silcpacket.h.
1597 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1598 SilcSFTPMonitorData to SFTP server to monitor various
1599 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1600 lib/silcsftp/sftp_server.c.
1602 * Added silc_file_size to return file size. Affected file
1603 lib/silcutil/silcutil.[ch].
1605 * Implemented the file transfer support for the client library.
1606 Added preliminary support for simple client to client one-file
1607 transmission. Affected file lib/silcclient/client_ftp.c,
1608 lib/silccilent/client.[ch].
1610 * Added new local command FILE to the Irssi SILC Client.
1611 It is used to perform the file transfer. It has subcommands
1612 SEND, RECEIVE, SHOW and CLOSE. Affected files
1613 irssi/src/silc/core/client_ops.c,
1614 irssi/src/silc/core/silc-server.[ch].
1616 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1618 * Relay the SILC_PACKET_FTP in the server. Affected files
1619 silcd/server.c and silcd/packet_receive.c.
1621 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1623 * Renamed silc_file_read and silc_file_write to functions
1624 silc_file_readfile and silc_file_writefile. Added function
1625 silc_file_open and silc_file_close. Affected files
1626 lib/silcutil/silcutil.[ch].
1628 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1630 * Resolve the client info when received private message or
1631 channel message for a client which nickname we don't know.
1632 Affected files lib/silcclient/client_prvmsg.c and
1633 lib/silcclient/client_channel.c.
1635 * Do not crash in /KEY if client is not connected. Affected
1636 file irssi/src/silc/core/silc-channels.c.
1638 * Added SilcClientStatus field to the SilcClientEntry in the
1639 lib/silcclient/idlist.h.
1641 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1642 is incomplete and is being resolved, it won't be resolved
1645 Make sure also that USERS command reply does not resolve
1646 twice information. Affected file is
1647 lib/silcclient/command_reply.c.
1649 Make sure that silc_client_get_clients_by_list does not
1650 resolve twice same information.
1652 * Check for valid client->id in the silc_server_free_client_data.
1653 Affected file silcd/server.c.
1655 * Fixed /GETKEY nick@server not to crash if the server entry
1656 is not found. Affected file lib/silcclient/command.c.
1658 * Fixed the silc_server_check_cmode_rights to check the
1659 requested modes correctly. Affected file silcd/command.c.
1661 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1663 * Better checks for non-printable chars in nick added.
1664 Affected file silcd/command.c.
1666 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1668 * Call the silc_server_udpate_servers_by_server in the
1669 primary router that comes back online in the backup resuming
1670 protocol. Otherwise it routes packets wrong. Affected file
1671 silcd/server_util.[ch], silcd/server_backup.c.
1673 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1675 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1676 lib/silcutil/silcbuffmt.[ch].
1678 * Redefined the SILC packet header to include the padding
1679 length. Affected file lib/silccore/silcpacket.[ch].
1681 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1682 length for maximum padding up to 128 bytes). Affected
1683 file lib/silccore/silcpacket.h.
1685 * Removed all backwards support for old 0.5.x MAC thingies.
1686 The SILC packet header change makes it impossible to be
1687 backwards compatible.
1689 * Send the ENDING packet with timeout in the backup resuming
1690 protocol. This is to assure that all routers has connected
1691 to the primary router. Affected file silcd/server_backup.c.
1693 * Changed the RNG to take the first IV from random data. It
1694 used to take it from zero actually. Changed the RNG also
1695 to use /dev/urandom during session. /dev/random is used
1696 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1698 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1700 * Changed the SILC packet header to have the first two bytes
1701 (the packet length) encrypted. Affected files aroung the
1702 code tree, lib/silccore/silcpacket.[ch]. Removed the
1703 SilcPacketCheckDecrypt callback. It is not needed anymore
1704 since the silc_packet_receive_process will determine now
1705 whether the packet is normal or special.
1707 * Implemented the unidirectional MAC keys. Affected files
1708 lib/silcske/silcske.c, silcd/protocol.c and
1709 lib/silcclient/protocol.c.
1711 * Implemented the packet sequence number to the MAC computation.
1712 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1713 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1714 lib/silcclient/protocol.c.
1716 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1718 * Allow backup router to announce servers. All servers
1719 announced by backup router are added to the global list
1720 automatically. Update hte server's socket to our primary
1721 router also when backup router announces a server.
1722 Affected file silcd/packet_receive.c.
1724 * Do not update the client->router in the function
1725 silc_server_udpate_clients_by_server if the client is on
1726 global list. We might fail to find any specific server
1727 for locally connected clients and local cell clients. They
1728 should still use the `from' and not `to' as client->router.
1729 This fixes backup router resuming protocol. Affected file
1730 silcd/server_util.c.
1732 * Decrease channel statistics count only if the channel
1733 deletion worked. Affected files are silcd/server.c and
1734 silcd/server_util.c.
1736 * Added silc_server_update_servers_by_server to update origin
1737 of all server entries. Used during backup router protocol.
1738 Affected files silcd/server_util.[ch], silcd/server.c. and
1739 silcd/backup_router.c.
1741 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1742 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1743 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1744 lib/silccrypt/silchmac.c.
1746 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1748 * Assure that router cannot reroute the same channel message
1749 to the sender. Affected file silcd/packet_receive.c.
1751 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1753 * Made better checks that the channel message is not sent
1754 to the router it came from. Affected file is
1755 silcd/packet_send.c. Fixed memory leak too.
1757 * Announce informations for incoming router connection, but
1758 only after checking if it is replaced by backup router.
1759 Affected file silcd/packet_receive.c.
1761 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1763 * Fixed the backup resuming protocol to work in multiple
1764 router environment. Affected file silcd/server_backup.c.
1766 * Route packet only to one router in the function
1767 silc_server_packet_send_to_channel. Affected file is
1768 silcd/packet_send.c.
1770 * Fixed silc_server_send_notify_dest to set the broadcast
1771 flag. Fixed the silc_server_send_notify_topic to actually
1772 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1773 Affected file silcd/packet_send.c.
1775 * Changed the SFTP Filesystem interface. Changed the
1776 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1777 the filesystem operation function. The SilcSFTPFilesystem
1778 is now a context that is allocated by all filesystem allocation
1779 functions and it already includes the operations structure
1780 and filesystem specific context. It is given as argument
1781 now to the silc_sftp_server_start. This made the interface
1782 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1783 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1785 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1787 * Changed the backup router adding and getting interfaces
1788 in the server. The router that will be replaced by the
1789 specified backup router is now sent as argument. Affected
1790 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1793 * Added silc_net_addr2bin_ne to return the binary form of
1794 the IP address in network byte order. Affected files
1795 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1797 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1799 * Check for existing server ID in silc_server_new_server
1800 and in silc_server_connect_to_router_final and remove the
1801 old entry if it exists. Affected file silcd/packet_receive.c,
1804 * Send the channel message always to only one router, either
1805 in upstream or downstream. Affected file is
1806 silcd/packet_send.c.
1808 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1810 * Wrote the definition of the backup resuming protocol to the
1811 protocol specification.
1813 * Removed one redundant channel key generation from normal
1814 server during joining procedure. Removed one redundant
1815 channel key sending from server to router during joining
1816 procedure. Affected file silcd/command.c.
1818 * Made minor bugfixes to the backup router resuming protocol.
1819 Affected file silcd/server_backup.c, server.c.
1821 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1823 * Added --disable-asm configuration option. Affected files
1824 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1827 * Implemented the backup resuming protocol that is used to
1828 resume the primary router position in the cell after the
1829 primary router comes back online. Affected files
1830 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1831 and silcd/server_util.[ch].
1833 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1835 * Sleep two (2) seconds after sending QUIT command to server.
1836 Affected file lib/silcclient/command.c.
1838 * Assure that if outgoing data buffer is pending do not force
1839 send any data. Affected file silcd/packet_send.c.
1841 * Assure that if outgoing data buffer is pending do not force
1842 send any data. Affected file lib/silcclient/client.c.
1844 * Implemented the backup router support when the primary router
1845 goes down. The servers and routers can now use the backup
1846 router as new primary router without loosing connectivity.
1848 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1850 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1851 in the server to indicate disabled entry. All data read
1852 from the connection will be ignored and no data is sent
1853 for entry that is disabled. Affected files are
1854 silcd/idlist.h, silcd/server.c.
1856 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1858 * Created SFTP client and server test programs in the
1859 lib/silcsftp/tests directory.
1861 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1863 * Implemented memory filesystem (virtual filesystem) for
1864 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1867 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1869 * Implemented the SFTP (SSH File Transfer Protocol) to the
1870 lib/silcsftp. It includes SFTP client and SFTP server
1873 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1875 * Moved lib/silccore/silcprotocol.[ch] to the
1876 lib/silcutil library.
1878 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1879 take variable argument list pointer as argument. Affected
1880 file lib/silcutil/silcbuffmt.[ch].
1882 * Added silc_buffer_set function that is used to set data
1883 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1884 Affected file lib/silcutil/silcbuffer.h.
1886 * Changed various routines in the core library to use the new
1887 silc_buffer_set instead of allocating new buffer only for
1890 * Added 64-bit value formatting and unformatting support to the
1891 silc_buffer_[un]format routines. Affected file is
1892 lib/silcutil/silcbuffmt.[ch].
1894 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1895 to includes/bitmove.h.
1897 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1899 * Fixed channel user mode saving in client library. Affected
1900 file lib/silcclient/command[_reply].c.
1902 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1904 * Defined the file transfer to the SILC Protocol. Added
1905 new packet type SILC_PACKET_FTP and defined File Transfer
1906 Payload. The mandatory file transfer protocol is SFTP
1907 (SSH File Transfer Protocol). Affected file in addition
1908 of the internet draft is lib/silccore/silcpacket.h.
1910 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1911 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1912 is used as part of backup router protocol when the primary
1913 router of the cell is back online and wishes to resume
1914 the position as primary router.
1916 * Redefined the MAC generation keys in the protocol. The
1917 same key is not used anymore in both direction. Both
1918 direction will now use different keys for sending and
1919 receiving. This fixes a potential security flaw. This
1920 change causes incompatibilities in the protocol.
1922 * Redefined also the MAC computation from the packet.
1923 An packet sequence number is now added to the MAC
1924 computation. This prevents possible replay attacks against
1925 the protocol. This change too causes incompatibilities
1928 Added `sequence' field to the SilcPacketContext to hold
1929 the current sequence number for the packet.
1931 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1933 * Added `created' field to the SilcIDListData in the file
1934 silcd/idlist.h to indicate the time when the entry was
1937 * Added `created' field to the SilcChannelEntry too. Affected
1938 file silcd/idlist.h.
1940 * Added `creation_time' aguments to all the announcement functions
1941 in the server. If it is provided then only the entries that
1942 was created after the provided time frame are actually
1943 announced. Affected file silcd/server.[ch].
1945 * The protocol says that the Channel ID's IP address must be
1946 based on the router's IP address. Added check for this in
1947 the silc_server_new_channel when processing incoming New Channel
1948 Payload. Affected file silcd/packet_receive.c.
1950 * Print out the correct version with --version in SILC client.
1951 Affected file irssi/src/silc/core/silc-core.c.
1953 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1955 * Fixed WHOWAS command to check for completnes of the client
1956 entry always, not just when the command is coming from client.
1957 Affected file silcd/command.c.
1959 * Added new function silc_server_packet_queue_purge to purge the
1960 outgoing data queue to the network. After the function returns
1961 it is guaranteed that the outgoing packet queue is empty.
1962 Affected file silcd/packet_send.[ch].
1964 * Purge the outgoing packet queue in the rekey protocol's final
1965 callback to assure that all rekey packets go to the network
1966 before quitting the protocol. Affected file silcd/server.c.
1968 * Added silc_client_packet_queue_parse as similar function as
1969 in server to the client library. The affected file is
1970 lib/silcclient/client.c.
1972 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1974 * Splitted silcd/server.c and created silcd/server_util.[ch]
1975 for utility functions.
1977 * Added new socket flag SILC_SF_DISABLED to indicate that the
1978 connection is open but nothing can be sent to or received from
1979 the connection. Affected file lib/silcutil/silsockconn.[ch].
1980 The checking for disabled socket is checked in the low level
1981 silc_socket_write and silc_socket_read functions.
1983 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1985 * Allow only nicknames and channel names that fits into the
1986 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1988 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1990 * When processing JOIN command reply in server check that if
1991 the channel exists in our global list we'll move it the local
1992 list. Affected file silcd/command_reply.c.
1994 * Fixed the check whether client is joined on the channel already
1995 in JOIN command. Affected file lib/silcclient/command.c.
1997 * Fixed the JOIN command reply to check whether the channel
1998 already exists. Affected file lib/silcclient/command_reply.c.
2000 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2002 * Added silc_ske_status_string to map the SKE error numbers
2003 to readable strings. The affected files are
2004 lib/silcske/silcske[_status].[ch].
2006 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2008 * Do not show the private channels on the WHOIS channel list
2009 as it is not allowed by the protocol. The affected file is
2012 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2014 * Assure that the packet length digged from the actual packet
2015 is something sensible in the silc_packet_decrypt_rest_special
2016 in lib/silccrypt/silcpacket.c.
2018 * Free and NULL the allocated pointer in silc_hmac_alloc if
2019 the HMAC allocation fails. The affected file is
2020 lib/silccrypt/silchmac.c.
2022 * Print the selected security properties to the log files in
2023 the server. Affected file silcd/protocol.c.
2025 * Add SKE's reference counter even if calling the completion
2026 callback manually. Otherwise it goes negative, although it
2027 does not cause any problems. The affected file is
2028 lib/silcske/silcske.c.
2030 * Remove the client entry with short timeout after giving the
2031 KILL command. Affected file lib/silcclient/command.c.
2033 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2034 case all found clients are already disconnected (WHOWAS would
2035 found them) in the server. Affected file silcd/command.c.
2037 * Update the last_receive (time of last data received) to be
2038 updated only when received private or channel message so that
2039 the idle time showed in WHOIS makes more sense.
2041 * Added boolean field `valid' in to the SilcClientEntry in the
2042 client library to indicate whether the entry is valid or not.
2043 This fixes the nickname change bug on channel when changing
2044 the nickname to be same than the old (like nick to Nick) the
2045 nickname formatter doesn't set the new nick anymore to Nick@host.
2046 Affected file lib/silcclient/idlist.[ch].
2048 * Now actually fixed the nickname changing on disconnection.
2049 Added new function silc_change_nick to the Irssi SILC Client.
2050 Affected file irssi/src/silc/core/client_ops.c,
2051 irssi/src/silc/core/silc-nicklist.[ch].
2053 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2055 * Check that the public key exists in the GETKEY command before
2056 trying to encode it. Affected file silcd/command.c.
2058 * Print some notifications on received public keys with GETKEY
2059 command in the Irssi SILC Client. Affected files are
2060 irssi/src/fe-common/silc/module-formats.[ch],
2061 irssi/src/silc/core/client_ops.c.
2063 * Use IDENTIFY command to resolve the server information in the
2064 GETKEY command instead of INFO command. Affected file
2065 lib/silcclient/command.c.
2067 * All command reply functions in the client library now calls
2068 the pending command reply callbacks even if an error has
2069 occurred. The server has done this a long time and now it was
2070 time to move the client library to this as well. Now all
2071 errors can be delivered back to the pending command reply
2072 callbacks if necessary. Affected files are
2073 lib/silcclient/command[_reply].[ch].
2075 * Change the nickname on disconnection back to the username
2076 because in reconnect the server will enforce it to it anyway.
2077 Affected file irssi/src/silc/core/silc-servers.c.
2079 * Fixed a config file parsing bug in the Irssi SILC client.
2080 Affected file irssi/src/silc/core/clientconfig.c.
2082 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2084 * When printing the channel mode on JOIN, verify that the
2085 channel key and channel's HMAC are valid. Affected file
2086 irssi/src/silc/core/client_ops.c.
2088 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2090 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2091 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2092 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2094 * Removed channel key rekey task deleting from the function
2095 silc_server_save_channel_key. Affected file silcd/server.c.
2096 Added explicit timeout task context instead that is used to
2097 delete the task if we are registering a new task before the
2098 new task has elapsed.
2100 * When channel key rekey occurs the client library now saves
2101 the old channel key for a short period of time (10 seconds) and
2102 is able to use it in case some is still sending channel
2103 messages encrypted with the old key after the rekey. Affected
2104 file lib/silcclient/[idlist.h|client_channel.c].
2106 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2108 * Added check to the silc_server_new_id_real to not accept
2109 new ID if it is the sender's own ID. Affected file is
2110 silcd/packet_receive.c.
2112 * Assure that we do not announce ourself or the one we've
2113 sending our announcements when we're router and are announcing
2114 servers to our primary router. Affected file silcd/server.c.
2116 * Fixed silc_server_command_identify_check_client to assemble
2117 correct WHOIS packet. It send corrupted WHOIS packet and
2118 caused problem with router to router connections. Affected
2119 file silcd/command.c.
2121 Fixed also silc_server_command_whois_check the same way
2122 as for the IDENTIFY command.
2124 * Added new SilcIDListStatus to the server in the SilcIDListData
2125 structure. The status now includes the current status of
2126 the entry (like registered, resolved etc.). Affected file
2127 silcd/idlist.[ch]. Defined a bunch of different status types
2128 as well. This replaced the old boolean registered field as well.
2130 Added resolve_cmd_ident field to the SilcClientEntry structure
2131 too so that if the entry is for example being resolved so
2132 another command may attach to the same pending command reply
2133 without requiring to resolve the same entry again. This concept
2134 should optimize the WHOIS and the IDENTIFY resolving under
2135 heavy load by taking away unnecessary resolving for entries
2136 that are being resolved already.
2138 Added support for adding multiple pending commands for one
2139 command idenfier. Affected file silcd/command[_reply].[ch].
2141 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2142 before deleting the data. Otherwise the hash table will have
2143 freed data in comparison functions. Affected file is
2144 silcd/command_reply.c.
2146 * Fixed silc_idlist_replace_client_id to add the new entry to
2147 the cache with NULL nickname. Otherwise there will be invalid
2148 memory as the nickname after the nickname is freed. Affected
2149 file silcd/packet_receive.c.
2151 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2152 saved into wrong slots because the previous number of entries
2153 was not taken into account. Affected file silcd/idlist.c.
2154 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2156 * If we are router and we receive JOIN notify to a channel that
2157 does not have any users then notified client is marked as the
2158 channel founder, as it is it. The affected file is
2159 silcd/packet_receive.c
2161 * Added to the extended hash table API's table_del_*ext functions
2162 the destructor as argument too, so that the caller can decide
2163 which destructor to use or whether to use destructor at all.
2164 Affected file lib/silcutil/silchashtable.[ch].
2166 * Fixed ID Cache purging. It actually deleted the entries from
2167 the hash table after the data was freed. The hash table ended
2168 up comparing freed memory. The affected file is
2169 lib/silccore/silcidcache.c.
2171 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2173 * Fixed Irssi SILC client's KILL command's HELP syntax.
2175 * The USERS command now resolves the detailed user information
2176 if the userinfo field is missing. Affected file is
2177 lib/silcclient/command_reply.c.
2179 * Do not print error in silc_file_read if the read file does
2180 not exist. Just silently return NULL. Affected file is
2181 lib/silcutil/silcutil.c.
2183 * Fixed the silc_log_output to not wine about NULL filename
2184 and to not create some bogus " " filename. Affected file is
2185 lib/silcutil/silclog.c.
2187 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2189 * Fixed various printing bugs on the user interface in the
2190 Irssi SILC Client. Minor changes that were forgotten from
2193 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2195 * Fixed the configure.in.pre and the compilation and distribution
2196 environment to support the new autoconf 2.52. That version is
2197 now required to compile the CVS trunk.
2199 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2201 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2202 to generally parse user@fqdn format strings. Affected file
2203 lib/silcutil/silcutil.c.
2205 * Added nickname_format and nickname_force_format fields to the
2206 SilcClientParams structure. The first one defines the format
2207 for the nicknames that the library will enforce if the receives
2208 multiple same nicknames. The second one is boolean value and
2209 can be used to force the library to always enforce the format
2210 to the nicknames regardles whether there are multiple nicknames
2211 or not. This configurable formatting was employed to flexibly
2212 support accessing multiple nicknames from the user interface.
2213 The userinterface can now set the nicknames to what ever format
2214 they prefer. Affected file lib/silcclient/silcapi.h.
2216 Added function silc_client_nickname_format to the file
2217 lib/silcclient/idlist.c. It performs the nickname formatting.
2219 Added new field `hostname´ to the SilcClientEntry context.
2220 It holds the hostname of the client. Affected file is
2221 lib/silcclient/idlist.h.
2223 * Irssi SILC Client sets the nicknames in nick@hostn format.
2224 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2225 irssi/src/silc/core/silc-core.c.
2227 The WHOIS printing now also shows both the real nickname and
2228 the formatted nickname so that user knows how to access the
2229 user if there are multiple same nicknames cached. Affected
2230 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2231 printing formatting too to take the hostname now as a separate
2232 argument. The Affected file is
2233 irssi/src/fe-common/silc/modules-formats.[ch].
2235 * Changed the silc_client_get_clients_local to accept the formatted
2236 nickname as argument. It accepts the real nickname too but the
2237 formatted nickname can be used to find the true entry from
2238 multiple entries. Affected file lib/silcclient/silcapi.h and
2239 lib/silcclient/idlist.c.
2241 * Added nickname_format_parse field to the SilcClientParams.
2242 It is a callback function provided by the application to parse
2243 the nickname out of the formatted nickname string. The library
2244 calls it to get the nickname from the formatted string. Since
2245 the application generally knows better the format of the nickname
2246 string it parses it instead of the library, even though library
2247 encodes the formatted string. If the callback function is not
2248 provided then the library will use the string as is. The
2249 affected file is lib/silcclient/silcapi.h.
2251 * All the nickname strings passed to the client library in
2252 commands are now expected to be formatted nickname strings.
2253 If the command does not support the formatted nickname string
2254 it will assume that the sent string is the actual nickname.
2255 Affected file lib/silcclient/command.c.
2257 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2259 * Added public key authentication support to OPER and SILCOPER
2260 commands in the client library. Affected file is
2261 lib/silcclient/command.c.
2263 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2265 * Changed the get_auth_methdod client operation to be asynchronous.
2266 It can be async if the application resolves the authentication
2267 method from the server during the negotiation. Added new
2268 SilcGetAuthMeth completion callback that the application will
2269 call after resolving the authentication method.
2271 Added function silc_client_request_authentication_method that
2272 the application can use to resolve the authentication method
2273 from the server. Added also SilcConnectionAuthRequest callback
2274 that the library will call after the server has replied. The
2275 application can call this function if it does not know the
2276 current authentication method.
2278 Affected files are lib/silcclient/client.c and
2279 lib/silcclient/silcapi.h.
2281 * The Irssi SILC client now automatically resolves the authentication
2282 method incase any configuration information is not present (and
2283 currently there never is). The affected file is
2284 irssi/src/silc/core/client_ops.c.
2286 * Fixed public key authentication from the client library.
2287 Affected file lib/silcclient/protocol.c. Changed also the
2288 protocol specification about the public key authentication in
2289 the connection authentication protocol. The actual data to be
2290 signed is now computed with a hash function before signing.
2292 * Fixed the public key authentication from the server as well.
2293 Affected file silcd/protocol.c.
2295 * Removed the mlock()'s from the memory allocation routines.
2296 Affected file lib/silcutil/silcmemory.c. The ./configure does
2297 not check anymore for the mlock(). Affected file is
2300 * Fixed USERS command in server to allow the execution of the
2301 command for private and secret channels if the client sending
2302 the command is on the channel. Affected file silcd/command.c.
2304 * Fixed silc_client_get_clients_local to return the clients
2305 count correctly. It could return wrong value. Affected file
2306 lib/silcclient/idlist.c.
2308 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2310 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2311 types. The assembler optimizations seemed not to like 64-bit
2312 data types. The assmebler optimizations thus are now enabled
2313 also for BSD systems as opposed to only enable them for Linux.
2315 * Do not check for threads at all on BSD systems. Affected
2316 file configure.in.pre.
2318 * Removed -n and -h options from the Irssi SILC Client since
2319 they are not used in silc.
2321 * Fixed the prime generation to assure that the first digit
2322 of the generated random number is not zero since our conversion
2323 routines does not like number strings that starts with zero
2324 digit. If zero digit is seen the random number is regenerated.
2325 This caused some corrupted RSA keys when the zero first digit
2326 was met. Affected file lib/silcmath/silcprimegen.c.
2328 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2330 * Fixed WIN32 configuration in the ./configure script.
2331 Fixed to include xti.h on environments that has it.
2332 Patches by Carsten Ilchmann and andrew.
2334 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2336 * Changed the silc_id_create_client_id to be collision
2337 resistant. It is now assured that there cannot be created
2338 two same client ID's. I suspect that some weird bugs in
2339 the server were actually caused by duplicate Client IDs.
2340 Affected file silcd/serverid.[ch]. A router receiving
2341 new ID now also assures and informs the sending server
2342 if the ID caused collision.
2344 * Changed the silc_id_create_channel_id to also assure that
2345 there are no collisions.
2347 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2349 * Statement about ignoring the Mutual Authentication flag when
2350 performing rekey with PFS was a bit misleading. It is ignored
2351 if it was set in the initial negotiation, it cannot be even
2352 set in the rekey. Fixed in the ke-auth draft. Started the
2353 new versions of the protocol drafts in the doc/.
2355 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2357 * Fixed a bug in silc_client_command_identify_save when saving
2358 new channel information. The channel name was no duplicated
2359 and caused crash on exit. Affected file is
2360 lib/silcclient/command_reply.c.
2362 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2364 * Fixed the getkey command handling in the server. Send just
2365 empty OK reply to the sender if the key could not be fetched
2366 (but everything else was ok, like the key just was not available).
2367 Changed the public key parameter to optional in the protocol
2368 specs so that empty OK reply can be sent. Affected file
2371 Added a message to Irssi SILC client to tell to user if the
2372 server did not return a public key.
2374 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2376 * Fixed a channel key regeneration bug. It registered new
2377 timeout tasks exponentially until all system resources were
2378 used. Affected file silcd/server.c.
2380 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2382 * Added the SILC Document generator to the scripts/silcdoc.
2383 It can be used to generate the Toolkit Reference Manual out
2384 of the source tree. Internally it will also use the RoboDoc
2385 generator now imported in util/robodoc.
2387 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2389 * Added couple of return's in rekey protocol if error orccurred
2390 during the protocol. The execution must be terminated.
2391 Affected file silcd/protocol.c. Also, terminate the protocol
2392 always with timeout.
2394 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2396 * The client's Client ID was created initally from the wrong
2397 nickname (it could have been in format nick@host) in the
2398 silc_server_new_client. Affected file silcd/packet_receive.c
2400 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2402 * Added some SILC_LOG_ERROR's to various error conditions
2403 if client could not be added to ID cache. Affected files
2404 silcd/packet_receive.c and silcd/server.c.
2406 * When client's sock->user_data is freed, NULL also the
2407 client->router and client->connection pointers. Added check
2408 for these pointers being NULL to various places around the
2409 code. Affected file silcd/server.c.
2411 * Added client->data.registered == TRUE checks to various
2412 places around the code to assure that unregistered client's
2413 are not handled when it is not allowed. Affected file
2416 * Added `bool registered' fields to all
2417 silc_idlist_[server|client]_get_* routines to indicate whether
2418 the fetched client needs to be registered or not. Affected
2419 file silcd/idlist.[ch].
2421 * Add your own entry as registered to the ID cache in the
2422 server. Affected file server.c.
2424 * Fixed a bug in silc_server_new_server. The SilcServer was
2425 set as the new server's context instead of SilcServerEntry.
2426 This naturally caused some weird bugs.
2428 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2430 * Do not delete the channel rekey task when adding it
2431 for in silc_server_create_channel_key.
2433 * Changed the silc_server_create_channel_key to return
2434 TRUE or FALSE to indicate the success of the channel key
2437 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2439 * Fixed MSVC++ project files and added missing files to
2440 Makefiles under win32/.
2442 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2444 * Do not add TCP_NODELAY flag if the operating system
2445 does not have it defined. Affected files are
2446 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2448 * Fixed buffer overflow from Irssi SILC Client. Affected
2449 file irssi/src/fe-common/core/themes.c.
2451 * Fixed double free in client library in the file
2452 lib/silcclient/client.c when disconnecting from server.
2454 * Applied double free patch from cras to Irssi SILC client.
2455 Affected files irssi/src/core/[modules/expandos].c
2457 * Fixed the disconnection handling to Irssi SILC Client.
2458 The application must call silc_client_close_connection
2459 in ops->connect client operation in case of failure of
2460 the connection. Affected file is
2461 irssi/src/silc/core/client_ops.c.
2463 * Do not set sock->protocol to NULL in the function
2464 silc_client_close_connection after executing the protocol's
2465 final callback since the sock might not be valid anymore.
2466 Affected file lib/silcclient/client.c.
2468 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2470 * Do not enable SILC_THREADS if the linking with libpthread
2471 did not happen. Affected file configure.in.pre.
2473 * Added notion to protocol specification that server must
2474 verify the sent authentication payload with CMODE when
2475 setting the channel founder key. Implemented it to the
2476 server. Affected file silcd/command.c.
2478 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2480 * Added _EXTRA_DIST SILC distribution variable to the
2481 distributions file. It is used to conditionally add extra
2482 files or directories to the specific distribution. Affected
2483 files ./prepare, Makefile.am.pre and distributions.
2485 Removed the `_' from the start of the distribution names.
2488 * Added README.WIN32 for instructions to compile the Toolkit
2491 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2493 * Fixed a double free in disconnection in the server. Affected
2494 file is silcd/server.c.
2496 * Fixed the lib/silcske/groups.c to work now also with GMP
2497 MP library. The string conversion did not work when using
2498 specific base and the base is indicated in the string as well.
2500 * Created win32/ directory which now includes MSVC++ specific
2501 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2502 It will appear only in the toolkit distribution
2504 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2506 * Changed the key material distribution function in case when
2507 the hash output is too short. The data is now concatenated
2508 a bit differently than it used to. Made the change to the
2509 SKE protocol specification.
2511 * Added better GMP detection to configure.in.pre. A patch
2514 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2516 * Fixed a minor bug in SKE that might cause some problem on
2517 some platforms. Affected file lib/silcske/silcske.c.
2519 * Added the cookie checking for initiator in the SKE. It checks
2520 that the responder returns the sent cookie unmodified. The
2521 affected file is lib/silcske/silcske.c. Added new SKE
2522 error type INVALID_COOKIE that can be sent during the
2523 negotiation. Fixed some memory leaks as well.
2525 * Added the "invalid cookie" error message to Irssi SILC client's
2528 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2530 * Added `task_max' field to the SilcClientParams to indicate
2531 the maximum tasks the scheduler can handle. If set to zero,
2532 default values are used. Affected file lib/silcclient/silcapi.h.
2534 * Fixed memory leaks in silc_client_close_connection. Affected
2535 file lib/silcclient/client.c.
2537 * Added silc_client_del_client_entry to client library to free
2538 all memory of given client entry. Affected file is
2539 lib/silcclient/idlist.[ch].
2541 * Added new functions silc_client_del_channel and
2542 silc_client_del_server to delete channel and server entries.
2543 Affected file lib/silcclient/[silcapi.h/idlist.c].
2545 * Removed silc_client_del_client_by_id from silcapi.h.
2547 * Fixed the INFO command to return the server's own info
2548 correctly when querying by Server ID. Affected file is
2551 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2553 * Removed the non-blocking settings in WIN32 code in the
2554 silc_sock_[read/write] and added SleepEx instead. Affected
2555 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2556 of input data is now checked with FIONREAD and ioctlsocket.
2558 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2560 * Call silc_schedule_task_del_by_context in the
2561 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2562 Affected file lib/silccore/silcprotocol.c.
2564 * Call silc_protocol_cancel for active protocols in the
2565 silc_server_close_connection if the funtion
2566 silc_server_free_sock_user_data has not been called.
2567 Affected file silcd/server.c.
2569 * Generic tasks cannot be deleted using the del_by_fd
2570 task deleting function since generic tasks does not match
2571 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2573 * Added a notion to SILCOPER help file that the SILCOPER works
2574 only on router server, not on normal server.
2576 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2578 * Added for WIN32 support for the new scheduler as well.
2579 Affected file lib/silcutil/win32/silcwin32schedule.c.
2581 * Fixed the SHA1 implementation to work on various platforms.
2583 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2585 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2586 API. It is part of the scheduler now. Everything else is
2587 as previously but some functions has changed their names.
2588 Checkout the lib/silcutil/silcschedule.h for the interface.
2589 Updated all applications to use the new interface. Affected
2590 files are lib/silcutil/silcschedule.[ch].
2592 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2594 * Found a bug in the SKE implementation. The HASH value,
2595 specified by the protocol, was not computed correctly. The
2596 public key of the responder was not added to the computation
2597 even though it is mandatory. Affected file lib/silcske/silcske.c.
2598 This unfortunately causes incompatibilities with older
2599 clients and servers.
2601 * Added WIN32 specific network init and uninit functions:
2602 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2603 the Winsock2. Affected file lib/silcutil/silcnet.h and
2604 lib/silcutil/win32/silcwin32net.c.
2606 * Set the socket always to nonblocking mode on WIN32 after
2607 reading data or writing data. Affected file is
2608 lib/silcutil/win32/silcwin32sockconn.c.
2610 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2612 * Fixed various compilation problems under WIN32. Affected
2613 files lib/silcutil/win32/silcwin32thread.c and
2614 lib/silcutil/win32/silcwin32schedule.c.
2616 * Removed all _internal.h #includes from public header
2617 files. Internal headers must never be included from
2620 Removed also the lib/silcske/payload_internal.h file.
2622 * All include files that may be needed (public and some others
2623 included by the public headers) by application developers are
2624 now copied to the ./includes directory. It does not copy any
2625 internal headers. Affected file Makefile.defines.pre and all
2626 Makefile.am's under lib/ and subdirs.
2628 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2630 * Do not change the ~/.silc directory's permissions automatically.
2631 Affected file irssi/src/silc/core/clientutil.c.
2633 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2635 * Do not cancel the protocol in silc_server_close_connection
2636 it might cause recursion. Now cancelled in the function
2637 silc_server_free_sock_user_data. Affected file silcd/server.c.
2639 * Fixed the silc_server_remove_clients_by_server to regenerate
2640 the channel keys correctly finally. Added also new function
2641 silc_server_remove_clients_channels to actually do it.
2642 Affected file silcd/server.c.
2644 * Fixed the silc_server_new_channel to not crash by giving
2645 wrong router to the new channel. Affected file is
2646 silcd/packet_receive.c.
2648 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2650 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2651 which is given as argument to the silc_client_alloc now.
2652 It can be used to configure the client and set various parameters
2653 that affect the function of the client.
2655 * The USERS command in server did not check whether the channel
2656 is private or secret. Affected file silcd/command.c.
2658 * Added new argument to the USERS command in protocol specification.
2659 The USERS command now can take the channel name as argument
2660 as well. Added support for this in client and server and
2661 updated the protocol specs.
2663 * Completed the GETKEY command in client. It can be now used
2664 to fetch also servers public key not only some clients.
2665 Affected files lib/silcclient/command[_reply].c.
2667 * Added silc_client_get_server to return server entry by the
2668 server name. Affected files lib/silcclient/silcapi.h and
2671 * Redefined the IDENTIFY command in protocol specification to be
2672 more generic. It now can be used to query information about
2673 any entity in the SILC Network, including clients, servers and
2674 channels. The query may be based either the entity's name
2675 or the ID. Added support for this in both client and server.
2677 Affected files silcd/command.c and lib/silcclient/command.c
2678 and command_reply.c.
2680 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2681 the _from_client and _from_server functions. Affected file
2684 * Added silc_client_get_channel_by_id_resolve to the file
2685 lib/silcclient/silcapi.h to resolve channel information by
2686 its ID. Added also silc_client_get_channel_by_id that
2687 does not resolve it from the server.
2689 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2691 * Added SilcServerEntry context into the client library
2692 to represent one server. The INFO command now allocates
2693 these to save the resolved server info. For now on the
2694 client library will also keep information about servers,
2695 connected and resolved with INFO.
2697 The INFO command now allocates the SilcServerEntry context
2698 and saves the server info there. The COMMAND_REPLY in
2699 the INFO now returns the parameters to application in
2700 same order as defined in the protocol specification.
2702 The entries are cached in the client->server_cache.
2704 * The INFO command is now issued after received the Client ID
2705 from the server. Affected file lib/silcclient/client.c.
2707 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2708 to the application as the mode changer might be server.
2709 It is guaranteed that NULL is not returned anymore to the
2710 application. Affected file lib/silcclient/client_notify.c.
2712 The ID Type is now also passed to the application so that
2713 it can check whether the returned entry is SilcClientEntry
2716 Added new function silc_client_get_server_by_id to return
2717 the server entry by ID. Affected files are the
2718 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2720 * Do not create the channel in the Irssi SILC Client when issuing
2721 the JOIN command but when received the sucessful JOIN command
2722 reply. Otherwise the channel might get created even though we
2723 could not join it. The Affected file is
2724 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2726 * Fixed a channel joining bug in router. The router must also
2727 check the channel modes, invite and ban lists etc. when serving
2728 the JOIN command sent by normal server. Affected file is
2729 silcd/command.c. The router now resolves the client's
2730 information from the server who sent the JOIN command if it
2731 does not know it, and processes the JOIN command only after
2734 * Changed the SilcCommandCb to take new argument; void *context2.
2735 Affected file lib/silccore/silccommand.h
2737 The second argument in the command callbacks in the server now
2738 includes the SilcServerCommandReplyContext if the command was
2739 called as pending command callback from the command reply.
2740 Otherwise it is NULL. When called as pending the status of the
2741 command reply will be checked and if it was erronous the
2742 error will be sent to the original sender of the command.
2743 This way the client always receives the error messages even
2744 though the server was actually the one who received the error
2745 when it resent the command to router, for example. Affected
2746 files silcd/command[_reply].[ch].
2748 * Fixed sending WHOWAS command's error message to client if
2749 the requested client could not be found. It was missing.
2752 * Changed the CMODE and CUMODE commands reply arguments in the
2753 protocol specification. The Channel ID is now sent in both
2754 of the commands to identify the channel. Implemented this
2755 new feature to the client and server. Affected files
2756 lib/silcclient/command_reply.c and silcd/command.c.
2758 * Made better checks for invite and ban lists in the JOIN
2759 command in server. Affected file silcd/command.c.
2761 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2763 * The server now performs the incoming host IP/DNS lookup
2764 using the silc_socket_host_lookup and thus does not block
2765 the server anymore. Affected file silcd/server.c.
2767 * Completed the multi-thread support for SILC Scheduler in
2768 the lib/silcutil/silcschedule.c.
2770 * Fixed the configure.in.pre to detect the pthread correctly
2773 * Fixed a deadlock in silc_task_queue_wakeup in the file
2774 lib/silcutil/silctask.c.
2776 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2778 * Added new function silc_schedule_wakeup that is used in
2779 multi-threaded environment to wakeup the main thread's
2780 schduler. It needs to be used when a thread adds a new task
2781 or removes a task from task queues. After waking up, the
2782 scheduler will detect the task queue changes. If threads
2783 support is not compiled in this function has no effect.
2784 Implemented the wakeup mechanism to both Unix and WIN32
2785 systems. Affected files are lib/silcutil/silcschedule.[ch],
2786 lib/silcutil/unix/silcunixschedule.c and the
2787 lib/silcutil/win32/silcwin32schedule.c.
2789 * Added new function silc_task_queue_wakeup to wakeup the
2790 scheduler by the specified task queue. Affected file
2791 lib/silcutil/silctask.[ch].
2793 * The silc_socket_host_lookup_start now wakes up the scheduler
2794 after adding the timeout task. Affected file is
2795 lib/silcutil/silcsockconn.c.
2797 * The silc_socket_host_lookup is synchronous now if the threads
2798 support is not compiled in. However, the callback is still
2799 called asyncronously through the scheduler, anyway. Affected
2800 file lib/silcutil/silcsockconn.c.
2802 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2804 * Added new function silc_socket_host_lookup to perform
2805 asynchronous IP and FQDN lookups for the socket connection.
2806 Affected files lib/silcutil/silcsockconn.[ch].
2808 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2810 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2811 that may or may not compile the mutex support in.
2813 Changed the silc_mutex_alloc interface. It allocates the
2814 mutex now to the sent pointer and returns TRUE or FALSE.
2816 Affected file lib/silcutil/silcmutex.h.
2818 * Wrote the SILC Task Queue interface to support multi-threads.
2819 Affected file lib/silcutil/silctask.[ch].
2821 * Wrote the SILC Scheduler to support multi-threads. Affected
2822 file lib/silcutil/silcschedule.c.
2824 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2826 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2827 in lib/silcutil/win32/.
2829 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2831 * Defined SILC Mutex API and SILC Thread API and implemented
2832 them for Unix. Affected files are
2833 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2834 lib/silcutil/unix/silcunixmutex.c and
2835 lib/silcutil/unix/silcunixthread.c.
2837 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2839 * Fixed the silc_server_remove_clients_by_server's channel
2840 key re-generation. The hash table handling was incorrect
2841 and would not work with many channels. Affected file is
2844 * Fixed some memory leaks around the server code.
2846 * Rewrote the silc_server_get_users_on_channel to support IPv6
2847 based Client ID's. Affected file silcd/server.c.
2849 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2850 specification. However, a separate document must be written
2851 to define the detailed signing procedure and the payload
2852 associated with the flag. Defined the flag to the
2853 lib/silccore/silcchannel.h as well.
2855 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2857 * Changed the dynamic tables to static size tables in the
2858 lib/silccrypt/silchmac.c.
2860 * Removed GCC dependencies from the code. A patch by cras.
2862 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2864 * Do not show the error "Error receiving packet bla bla"
2865 in server if it really was not an error (-2 means that reading
2866 is pending). Affected file silcd/server.c.
2868 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2870 * Fixed a possible crash in silc_server_remove_clients_by_server
2871 in silcd/server.c. Fixed there also some memory leaks.
2873 * Fixed the silc_idlist_replace_client_id. It could replace
2874 wrong key in the hash table. Affected file silcd/idlist.c.
2876 * Do not check whether there are global users on the channel
2877 if the channel->global_users is FALSE. Affected functions
2878 silc_server_remove_from_one_channel and
2879 silc_server_remove_from_channels in silcd/server.c. Also,
2880 do not check if the removed client is local as we can be
2881 sure that global client was not removed from the channel
2882 and checking for global users is not needed.
2884 * The silc_server_remove_clients_by_server now re-generates
2885 the channel keys correctly for those channels that had
2886 clients removed from them. Affected file silcd/server.c.
2888 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2890 * Found the reason of random crashes in the server. We weren't
2891 ignoring the SIGPIPE signal (which can be sent in write())
2892 and it crashed the server. Affected file silcd/silcd.c.
2894 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2896 * Assure that sock->user_data is not NULL in the function
2897 silc_server_packet_send in silcd/packet_send.c.
2899 * Disconnect the remote connection if it could not be added
2900 to any ID lists in the server. The affected file is
2903 * Check in silc_server_packet_send[_real/dest] that the
2904 socket is not disconnecting and ignore the data if it is.
2905 Affected file silcd/packet_send.c.
2907 * Define inline to __inline on native WIN32 compilation.
2908 Affected file includes/silcwin32.h.
2910 * Added some explicit type casts for inline code since MSVC
2911 require them. Affected files lib/silcutil/silcbuffer.h,
2912 lib/trq/silcdlist.h and lib/trq/silclist.h.
2914 * Print warning in log files from now on if the packet
2915 decryption fails. Affected file silcd/server.c.
2917 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2919 * Changed the `say' client operation's interface to accept
2920 new `type' argument to indicate the type of the message sent
2921 by the library. The application may filter the library's
2922 messages according the type. The affected file is the
2923 lib/silcclient/silcapi.h.
2925 * Added two new functions to lib/silcclient/silcapi.h:
2926 silc_client_del_client and silc_client_del_client_by_id.
2927 Affected file lib/silcclient/idlist.c.
2929 * Moved the clientincludes.h from includes/ to silc/ and
2930 serverincludes.h from includes/ to silcd/.
2932 * The modes for the CMODE and CUMODE are now passed as
2933 uint32 for application with COMMAND_REPLY. The affected
2934 file is lib/silcclient/command_reply.c.
2936 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2938 * /WHOIS without arguments shows client's own information.
2939 Affected file lib/silcclient/command.c.
2941 * Changed PING to not accept any arguments. The specs
2942 says that client can ping only the connected server so
2943 requiring an argument is not needed. Affected file is
2944 lib/silcclient/command.c.
2946 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2948 * Fixed a fatal bug in private message sending and reception
2949 encryption and decryption when using private message keys.
2950 The implementation was incorrect and did not follow the
2951 specification. It causd that some of the message were
2952 lost since it did not use the sending and receiving keys
2953 as the protocol suggests. This has been fixed and will cause
2954 incompatibilities with older clients when sending private
2955 message encrypted with private message keys. Affected files
2956 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2957 and various other in Irssi SILC Client.
2959 Added `responder' boolean argument to the functions
2960 silc_client_add_private_message_key[_ske] to indicate when
2961 the key is added as responder or initiator of the key
2964 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2966 * Removed the silc_ske_check_version function and created
2967 a SilcSKECheckVersion callback. Added also a function
2968 silc_ske_set_callbacks that is now used to set all SKE
2969 callbacks. The callback functions are not given to
2970 the SKE functions anymore, but this function is used to
2973 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2975 * Added `silc_version' argument to the silc_client_alloc
2976 to define the version of the application for the library.
2977 The library will use the version string to compare it
2978 against the remote host's (usually a server) version
2979 string. Affected file lib/silcclient/silcapi.h
2981 * Added the KE protocol context to Key Agreement context
2982 in client library so that we can abort the SKE if it
2983 is in process when we get timeout. Affected file is
2984 lib/silcclient/client_keyagr.c.
2986 * Do not resolve the client ID forever if it returns in the
2987 first time that such client does not exist. This was done
2988 for example with private message. Affected file is
2989 lib/silcclient/client_prvmsg.c.
2991 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2993 * Do not add regex.h for WIN32. The affected file
2994 includes/silcincludes.h.
2996 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2997 not work yet 100%. It generates the DLL's automatically
2998 when compiling with --with-win32 under cygwin.
3000 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3002 * lib/contrib/regex.c is not compiled on WIN32.
3004 * Added silc_net_get_socket_opt function to the
3005 lib/silcutil/silcnet.h.
3007 * Added includes/silcwin32.h for WIN32 specific includes
3010 * Do not use ptime structure or any of the posix process
3011 functions on WIN32 in lib/silccrypt/silrng.c.
3013 * Added silc_gettimeofday to provide generic function
3014 for struct timeval on all platforms. Added the function
3015 to lib/silcutil/silcutil.h.
3017 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3019 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3020 library as they clearly belong there. As a plus side we
3021 can make the actual socket connection routines platform
3024 Added also new generic function silc_socket_read and
3025 silc_socket_write (that used to be silc_packet_[read/write].
3026 The implementation of these are platform specific.
3028 * Added WIN32 specific routines of silc_socket_[read/write]
3029 to lib/silcutil/win32/silcwin32sockconn.c.
3031 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3033 * Added preliminary support for native WIN32 compilation under
3034 cygwin (using the -mno-cygwin option for GCC) to the
3035 ./configure.in.pre. The --with-win32 now prepares the
3036 compilation for native WIN32.
3038 * Rewrote the SILC Scheduler interface in the file
3039 lib/silcutil/silcschedule.h. The scheduler is now context
3040 based and does not have anymore any global static scheduler.
3041 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3042 and created lib/silcutil/win32 directory for WIN32 based
3045 * Added Unix specific network routines to the
3046 lib/silcutil/unix/silcunixnet.c and the old
3047 lib/silcutil/silcnet.c includes now only generic routines.
3049 Added WIN32 specific network routines to the
3050 lib/silcutil/win32/silcwin32net.c.
3052 * Added Unix specific utility functions from the
3053 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3055 * Added WIN32 SILC Scheduler to the file
3056 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3059 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3061 * Do not handle JOIN notify in the server if the target client
3062 is not registered (idata->registered == FALSE). The affected
3063 file is silcd/packet_receive.c.
3065 * Update the nickrec->founder in event_cumode in the Irssi SILC
3066 client. Affected file irssi/src/silc/core/silc-channels.c.
3068 * Fixed the CUMODE_CHANGE notify handling in the server when
3069 server and router are announcing their clients on channels.
3070 Now the mode changes are saved and notified correctly. The
3071 affected file is /silcd/packet_receive.c.
3073 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3074 They really did not replace the cache entry in the ID Cache.
3075 Now they do that. Affected file silcd/idlist.c.
3077 * Fixed the KICK notify handling in the Irssi SILC client to
3078 update the channel records so that the kicked client does not
3079 appear to be on the channel. The affected file is
3080 irssi/src/silc/core/silc-channels.c.
3082 * Always update the conn->current_channel when executing command
3083 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3085 * Fixed the KILL notify handling in Irssi SILC client to remove
3086 the killed client on all channels.
3088 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3090 * Fixed the silc_parse_command_line to remove extra spaces
3091 from the start and end of the arguments. Affected file is
3092 lib/silcutil/silcutil.c.
3094 * Cancel and free any active protocol in the function
3095 silc_server_close_connection. Affected file silcd/server.c.
3097 * Cancel and free any active protocol in the function
3098 silc_client_close_connction. Affected file is
3099 lib/silcclient/client.c.
3101 * Do not execute the KILL command for clients that are in
3102 history (ie. they are not in the network). Affected file is
3105 * Fixed KILL notify handling, client does not crash anymore.
3106 Affected file irssi/src/silc/core/silc-channels.c.
3108 * Reduced the default packet buffer size from 2048 to 1024 in
3109 lib/silccore/silcpacket.c.
3111 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3112 counter to the SKE context that is incresed when the SKE library
3113 performs async operation outside the library. If the outside
3114 process frees the SKE context and FREED status will be set
3115 and the library will detect after the sync operation that the
3116 libary is freed. The affected files are
3117 lib/silcske/silcske[_status].[ch].
3119 * Resolve the client entry information in the function
3120 silc_client_channel_message to assure that NULL pointer is not
3121 passed as client entry to the application. */
3123 * Fixed the task timeout calculation to assure that there is
3124 never negative timeouts. The affected file is
3125 lib/silcutil/silcschedule.c.
3127 * Fixed the channel user mode notification sending in server.
3128 It was sent point-to-point to the router (or to server by router)
3129 but it needs to be destined to a channel. The routines now
3130 supports sending the channel user mode notifys to the channels
3131 when announcing clients and channels. Affected files are
3132 silcd/server.c and silcd/packet_receive.c.
3134 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3135 It did not actually replace the old channel entry in the cache.
3136 Affected file lib/silcclient/client_notify.c.
3138 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3140 * Fixed a possible crash in silc_packet_send_prepare. It now
3141 assures always that there is enough space in the buffer and
3142 at the tail area of the buffer (for MAC).
3144 Fixed the inbound buffer reallocation in silc_packet_read.
3145 It was old code and did not handle the reallocation correctly.
3148 The affected file is lib/silccore/silcpacket.c.
3150 * Fixed buffer overflow in silc_parse_nickname in the file
3151 lib/silcutil/silcutil.c.
3153 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3155 * make install generates new server keys only if there is not
3158 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3160 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3161 Added check that if the NOREPLY is set then we will not send
3162 the away message. This avoids infinite loop of away messages
3163 if both clients are away. The affected file is
3164 lib/silcclient/client_prvmsg.c.
3166 * Fixed client crash if /NICK was given without arguments.
3167 Affected file lib/silcclient/command.c.
3169 * Server does not send the invite list in INVITE command back
3170 to the client if the list was not altered. Added this notion
3171 to the protocol spec as well. Affected file silcd/command.c.
3173 Fixed possible crash in INVITE command by checking the
3174 value of silc_server_get_client_route command.
3176 * Fixed the INVITE notify type handling. The arguments are now
3177 taken in correct order and client does not crash. The affected
3178 file is irssi/src/silc/core/silc-channels.c.
3180 Removed the "Inviting xxx to channel" message from the
3181 client library away and let the application handle it.
3182 Affected file lib/silcclient/command.c. Added that message
3183 to Irssi SILC client's message formats.
3185 * Fixed CMODE command crash in client. It now checks the
3186 amount of arguments correctly and does not crash. The affected
3187 file is lib/silcclient/command.c.
3189 * Do not create new channel automatically in silc_channels_join
3190 but check whether the channel by that name already exists.
3191 Affected file irssi/silc/core/silc-channels.c.
3193 * Do not send the SERVER_SIGNOFF to router if the disconnected
3194 entity was the router. Affected file silcd/server.c.
3196 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3197 SILC client as it was missing from there.
3199 Added the handling of the KICK notify to the Irssi SILC client
3200 as it was missing. Added "you have been kicked" message to
3201 Irssi SILC client's message modules formats.
3203 Added the handing of the KILL notify to the Irssi SILC client
3204 as it was missing. Added the kill message module formats
3207 The affected file is irssi/src/silc/core/silc-channels.c.
3209 * The router did not save the channel mode the server announced.
3210 Affected file silcd/packet_receive.c.
3212 * Fixed a possible crash in INFO command in server. If the
3213 server did not provide the server info it crashed. Affected
3214 file silcd/command.c.
3216 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3218 * Fixed the GETKEY command in the server to check also the
3219 global list. Otherwise the GETKEY would not work correctly
3220 in normal SILC server. Affected file silcd/command.c.
3222 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3224 * Fixed GETKEY crash, it crashed if the command did not succseed.
3226 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3228 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3229 is now real and not just an macro interface to GMP.
3231 Removed the entire GMP from the source tree and imported new
3232 NSS MPI library instead. Reason for removing GMP is that it is
3233 extremely large and compiles extremely slow. The NSS MPI
3234 is only a few files and compiles in less than 10 seconds.
3235 The speed is also about the same as GMP. The MPI is imported
3236 to lib/silcmath/mpi.
3238 If the system has GMP installed we will still use the GMP.
3239 If it is not then the NSS MPI will be compiled.
3241 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3243 * Merged a long nickname (127 characters long) crash bugfix from
3244 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3246 * Merged a freed memory reference bugfix from Irssi CVS tree.
3247 Affected file irssi/src/core/commands.c.
3249 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3251 * Added the server's public key sving and verification to the
3252 server when performing the SKE. This was missing and the
3253 remote server's (or router's) public key was accepted without
3254 checking whether we have it previously or trust it at all.
3255 Affected file silcd/protocol.c.
3257 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3259 * Check in the silc_server_timeout_remote if protocol is active
3260 and make sure that the protocol's final callback is called so
3261 that all memory if freed. Affected file silcd/server.c.
3263 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3265 * silc_server_whois_send_reply crashed the server if the nickname
3266 was 127 characters long. Affected file silcd/command.c.
3268 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3270 * Added sanity check to the silc_server_new_client. If the hostname
3271 is provided inside username then check that the provided hostname
3272 really is the same as the resolved one. If the hostname was not
3273 resolved then check it from the public key. Affected file is
3274 silcd/packet_receive.c.
3276 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3277 if the server disconnected us and the connection is not valid
3278 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3280 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3281 the library to the lib/silcutil/silcutil.[ch].
3283 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3285 * Close log file after open. Affected file
3286 lib/silcutil/silclog.c.
3288 * Check whether sock == NULL in silc_client_send_packet and return
3289 if it is. Affected file lib/silcclient/silcclient.c.
3291 * Check rec->entry == NULL in the Irssi SILC Client before
3292 sending the channel message. Affecte file is
3293 irssi/src/silc/core/silc-servers.c.
3295 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3297 * Merged a splitted window bugfix from Irssi CVS tree. The
3298 affected file is irssi/src/fe-text/textbuffer-view.c.
3300 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3301 It did not print nickname.
3303 * Improved the distributions system a bit.
3305 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3308 irssi/src/fe-text/gui-window.c.
3310 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3311 to in-active server. The affected file is
3312 irssi/src/silc/core/client_ops.c.
3314 * Resolve the client in USERS command reply if the entry does
3315 not have username resolved. The affected file is
3316 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3317 command to WHOIS command to really resolve stuff. The USERS
3318 is not used any more in any critical section so WHOIS can
3319 be used even though it might be slower than IDENTIFY.
3321 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3324 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Changed the protocol API a bit more consistent in the
3327 lib/silccore/silcprotocol.[ch].
3329 * Changed the following headers to ROBODoc format:
3331 lib/silccore/silcpayload.h
3332 lib/silccore/silcprotocol.h
3333 lib/silccore/silcsockconn.h
3335 All core library headers are now formatted.
3337 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3339 * Fixed a bug in Irssi SILC client; do not show that you are
3340 server/router operator if you really are not. Affected file is
3341 irssi/src/silc/core/client_ops.c.
3343 * Renamed silc_command_free_payload to silc_command_payload_free.
3344 Affected file lib/silccore/silccommand.h
3346 * Added silcmath.h to include the prototoypes of various routines
3347 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3350 * Changed the following headers to ROBODoc format:
3352 lib/silccore/silcchannel.h
3353 lib/silccore/silccommand.h
3354 lib/silccore/silcid.h
3355 lib/silccore/silcidcache.h
3356 lib/silccore/silcmode.h
3357 lib/silccore/silcnotify.h
3358 lib/silccore/silcpacket.h
3359 lib/silcmath/silcmath.h
3361 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3363 * Added checking to the server code not to start the server if
3364 ciphers and stuff are not configured properly. Affected files
3365 silcd/serverconfig.[h] and silcd/server.c.
3367 * Changed the layout of the header files of the public interfaces
3368 in the SILC libraries. The new layout supports ROBODoc
3369 documentation tool (and some others) so that it is easy to create
3370 a library reference manual. All the other headers and source
3371 code must still follow the CodingStyle document. Also source
3372 code must not include these ROBODoc stuffs, only the headers.
3373 Furthermore, all public interface headers must now be named
3374 by using `silc' prefix, example: silcapi.h, silccipher.h.
3375 Some files were renamed due to this. All the other headers
3376 must not be used as public interfaces. I will update the
3377 CodingStyle document later. Changed following headers, so far:
3379 lib/silcclient/silcapi.h
3380 lib/silccore/silcauth.h
3381 lib/silccore/silcprivate.h
3382 lib/silccrypt/silcdh.h
3384 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3388 * Removed silc_client_packet_send_flush from the client library
3389 as it is not needed. Affected file lib/silcclient/client.[ch].
3391 * Added printing of message of unresolved authentication method
3392 to the Irssi SILC client. Added it to the module formats.
3393 Removed the same message from the client library.
3395 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3397 * Added new distribution feature, DISTLABEL. Every distribution
3398 can define own preprocessor label that can be used in the
3399 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3400 file distributions, acconfig.h.pre and prepare.
3402 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3404 * Added Makefile.defines_int to include the actual definitions
3405 for Makefile.defines.in. Tested the new distribution system,
3406 created distributions and tested installation.
3408 * Added AWAY message printing to the Irssi SILC client. Added
3409 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3411 * Added SCONNECT command to call the SILC's CONNECT command.
3412 Cannot use CONNECT directly since Irssi uses that internally.
3413 Affected file irssi/src/silc/core/silc-servers.c.
3415 Added ACTION local command. It is same as ME command but takes
3416 the channel as mandatory argument.
3418 Rewrote some of the Irssi's help files to suite for SILC
3421 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3423 * Added Makefile.defines[.in] that should for now on be included
3424 in all Makefile.am file in the source tree. That file includes
3425 all common compilation definitions for SILC source tree.
3427 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3429 * Minor changes to the ./prepare script to change the package
3430 name according the distribution name to the configure.in.
3432 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3434 * Created new distribution system. Added file `distributions'
3435 that defines all the distributions that can be created out of
3436 the SILC source tree. The ./prepare script now reads that
3437 file to determine how to prepare the distributions. The
3438 first argument to the ./prepare is the name of the distribution
3439 and second is the version of the distribution. If given
3440 without arguments it creates the default (toolkit) distribution
3441 with the default version (defined in ./prepare).
3443 All Makefile.am files that are subject to the distributions
3444 are now named as Makefile.am.pre. These are ./Makefile.am
3445 and lib/Makefile.am. Others may be changed later.
3447 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3449 * Added invite list, ban list, some key management and connection
3450 error message printing to module formats in the Irssi SILC client.
3452 * Added new silc_client_set_away_message to set the away message
3453 that is back to the person who sent private message. The
3454 affected file lib/silcclient/silcapi.h and the
3455 lib/silcclient/client_prvmsg.c.
3457 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3459 * Fixed the private message sending in the Irssi SILC client,
3460 added local command KEY to the Irssi SILC client.
3462 Added key management and key agreement message formats to the
3463 irssi/src/fe-common/silc/module-formats.[ch].
3465 Added USERS (alias WHO) printing, server/router operator
3466 indication and LIST command printing to the module formats.
3468 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Fixed channel joining notify handling, cumode notify handling
3471 from Irssi SILC client.
3473 * Added SILC specific module-formats to the Irssi SILC client so
3474 that SILC specific message hilighting, colors etc is possible.
3475 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3477 Added channel mode, channel user mode, actions, notices,
3478 whois and whowas printing to the the module-formats.c.
3480 * Fixed a bug in channel deletion in the server. The channel
3481 is not left to the cache even if the channel founder auth mode
3482 is set when there are no users anymore on the channel. Affected
3483 file silcd/server.c.
3485 * The silc_net_localhost now resolves the entire hostname including
3486 the domain name. Affected file lib/silcutil/silcnet.c.
3488 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3490 * Changed the ask_passphrase client operation to be ascynchronous.
3491 It has now a completion callback and a context that the
3492 application must call after it has got the passphrase from
3493 the user. Affected files lib/silcclient/silcapi.h,
3494 lib/silcclient/protocol.c, lib/silcclient/command.c and
3497 Added SilcAskPassphrase callback that the application calls
3498 to deliver the passphrase to the library.
3500 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3501 The public key verification and especially a certificate
3502 verification is asynchronous procedure.
3504 Added new SILC_SKE_STATUS_PENDING status to indicate the
3505 request is pending and a callback will be called to finalize
3508 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3509 indicate that remote end did not send its public key (or
3510 certificate), even though we require it. Added check for this
3511 condition in the SKE. This was a security bug, now fixed.
3513 Defined new SilcSKEVerifyCbCompletion callback that is called
3514 when the verification process is completed.
3516 The affected files lib/silcske/silcske_status.h and
3517 lib/silcske/silcske.[ch].
3519 * Changed the verify_public_key client operation to be async
3520 as well. Defined SilcVerifyPublicKey callback that is used to
3521 indicate the success of the public key verification process.
3523 Changed the server and client to use the new async client
3526 * Changed the Irssi SILC client's internal scheduler to be called
3527 twice as many times as it used to be. As a result the client
3528 should be a bit faster now. Affected file is
3529 irssi/src/silc/core/silc-core.c.
3531 * Added support to Irssi SILC client of asynchronous public key
3532 verification and passphrase inquiry. Affected file is
3533 irssi/src/silc/core/silc-core.c.
3535 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3537 * Do not say "You have left channel %s" in client library.
3538 Moved it to the application. Affected files are
3539 lib/silcclient/command.c and silc/client_ops.c.
3541 * Fixed silc_client_get_clients. Command context was not
3542 duplicated and was freed memory in the callback. Affected
3543 file lib/silcclient/idlist.c.
3545 * Do not say "you are now talking..." on JOIN command in the
3546 client library. The appliation must handle it.
3548 * Do not say ".. changed topic to" in command reply in the
3549 client libary. The application must handle it.
3551 * Fixed TOPIC command sending in the client library.
3553 * Fixed a memory leak in silc_client_command_free in the file
3554 lib/silcclient/command.c.
3556 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3558 * Imported a modified version of Irssi client to the source tree.
3559 The Irssi will be used to create a new client called
3560 Irssi SILC. Imported to irssi/.
3562 Added silc_core_init_finish function to the Irssi. Affected
3563 file irssi/configure.in.
3565 A lot changes in the Makefile.ams around the irssi tree.
3567 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3569 * Do not rehash if the new size is same as the old size of the
3570 hash table, in the silc_hash_table_rehash*. The affected file
3571 lib/silcutil/silchashtable.c.
3573 * Replaced hash_table_del_by_context calls from the server
3574 (when channel->user_list and client->channels) to the
3575 hash_table_del as it is sufficient and faster.
3577 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3579 * Added silc_hash_table_list, silc_hash_table_get and the
3580 SilcHashTableList structure to provide an alternative way to
3581 traverse the hash table. The affected files are
3582 lib/silcutil/silchashtable.[ch].
3584 * Changed the server's idlist routines to use the hash table
3585 routines to optimize the code.
3587 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3589 * Replaced the client entry's `channel' list and channel entry's
3590 `user_list' list to hash tables for optimized lookup. Changed
3591 the code to use the hash table interface around the code.
3592 Affected file lib/silcd/idlist.[ch].
3594 * Added `auto_rehash' boolean argument to the function
3595 silc_hash_table_alloc to indicate whether the hash table should
3596 auto-rehash when it thinks is appropriate time. It will
3597 increase the hash table size if the there is twice as much
3598 entries in the table than the size of the table, and will
3599 decrease the size if there are twice as less entries than
3600 the size of the table.
3602 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3604 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3606 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3608 * silc_idcache_purge_by_context deletes the entry now by context
3609 as it is supposed to do. Affected file lib/silccore/idcache.c.
3611 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3612 client is not anymore valid (WHOWAS givens the info) and not
3613 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3615 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3617 * Removed the `data' and `data_len' arguments from the ID Cache
3618 interfaces and added `name' argument. ID Cache does not handle
3619 anymore the binary data only a names associated with given ID.
3621 * When hashing a Client ID with silc_hash_id the entire ID is
3622 not hashed anymore, instead only the hash of the Client ID is
3623 hashed. This way we can access the Client ID from the cache
3624 with Client ID but with the hash of the ID (which is a hash of
3625 the nickname) as well without any difference in performance.
3627 Added also silc_idcache_find_by_id_one_ext to do one on one
3628 searching when we have the actual ID. Added also function
3629 silc_hash_client_id_compare. The affected files are
3630 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3632 * When hashing the name associated with a ID it is always done
3633 in lowercase. This way we can access the cache without worrying
3634 about case-sensitivity, even though, for example nicknames are
3637 * Fixed a bug in server with channel message sending. It put
3638 wrong ID type as destination ID. The affected file
3639 silcd/packet_send.c.
3641 * silc_idcache_del_by_context now deletes from all hash tables
3642 by context. Affected file lib/silccore/idcache.c.
3644 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3646 * Changed the client library to use the new ID Cache interface.
3647 Changes around the source tree.
3649 * Added silc_hash_table_rehash_ext to rehash with specific
3650 hash function. Affected file lib/silcutil/silchashtable.[ch].
3652 * Added silc_hash_string_compare to compare two strings in the
3653 hash table. Affected file lib/silcutil/silcutil.[ch].
3655 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3657 * Added new function silc_idcache_del_by_context into the
3658 lib/silccore/idcache.[ch].
3660 * Changed the server's ID list routines to use the new ID Cache
3661 interface. Changes around the source tree.
3663 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3665 * Added silc_hash_table_del[_by_context]_ext functions in to the
3666 lib/silcutil/silchashtable.[ch].
3668 Removed silc_hash_table_find_all* routines and added new
3669 silc_hash_table_find_foreach to replace them.
3671 Added silc_hash_table_replace_ext function as extended
3672 replacing function. Separated the simple hash table interface
3673 from the extended hash table interface in the file
3674 lib/silcutil/silchashtable.h.
3676 * Fixed minor bugs and changed it to use some of the new
3677 hash table functions in lib/silccore/idcache.c
3679 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3681 * Added new function silc_hash_table_find_all to return all keys
3682 in the hash table by the specified key. As the hash table is
3683 collision resistant it also makes it possible to have several
3684 duplicate keys in the hash table. This function may be used to
3685 find all of the keys from the hash.
3687 Added user_context arguments to the SilcHashFunction,
3688 SilcHashCompare and SilcHashDestructor to deliver user specified
3691 Added new fuctions silc_hash_table_find[_all]_ext to do
3692 extended lookup with specified hash and compare functions and
3693 specified user contexts.
3695 Added new function silc_hash_table_add_ext to add the key
3696 with specified hash function and user context.
3698 Added new function silc_hash_table_foreach to traverse all
3699 entrys in the hash table. Added SilcHashForeach callback
3702 Added new function silc_hash_table_del_by_context to delete
3703 the entry only if the context associated with the key matches.
3705 Affected files are lib/silcutil/silchashtable.[ch].
3707 * Removed silc_hash_[server/client/channel]_id and added just
3708 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3709 silc_hash_id_compare to compare two ID's using as the hash table
3710 comparison function. Added also silc_hash_data to hash
3711 binary data and silc_hash_data_compare to compare it.
3713 * Removed silc_idlist_find_client_by_hash as it is not needed
3714 anymore. Affected file silcd/idlist.[ch].
3716 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3717 to use internally the SilcHashTable. The new ID Cache is a lot
3718 faster than the old one. Some of the ID Cache interface was also
3719 rewritten and obsolete and stupid functions were removed.
3721 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3723 * Added entry_count field to the SilcHashTable to keep the number
3724 of the entries in the table. Implemented the function
3725 silc_hash_table_rehash. Added new function
3726 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3728 Fixed a minor bug in silc_hash_table_free.
3730 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3731 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3732 into the lib/silcutil/silcutil.[ch].
3734 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3736 * Implemented a collision resistant hash table into the
3737 lib/silcutil/silchashtable[ch]. See the header and the source
3738 for the SilcHashTable API.
3740 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3742 * Merged dotconf version 1.0.2 into lib/dotconf.
3744 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3746 * Do not compile anything in lib/silcsim/* if the SIM support
3747 is not enabled. The tree should now compile without problems
3750 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3752 * Compiled the SILC under cygwin. Compiled and tested briefly
3753 without problems. More tests needed. The SIMs didn't compile
3756 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3758 * Fixed possible crash in silc_get_username in the
3759 lib/silcutil/silcutil.c.
3761 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Fixed a va_arg in silc/client_ops.c.
3765 * Oops, RC5 routines were named AES and caused some problems
3766 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3768 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3770 * Added new SilcIDIP structure into the lib/silccore/id.h and
3771 replaced the old `ip' fields from all SILC ID's to that type.
3772 This is a step towards IPv6 support.
3774 The silc_id_get_len takes now the ID as an extra argument.
3775 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3776 both IPv4 and IPv6 based ID's.
3778 The affected files are lib/silccore/id.[ch] and other files
3779 around the tree using these routines.
3781 * Removed the ID length arguments in server from various
3782 silc_server_send_notify_* routines -> they are not needed
3785 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3787 * Fixed memory leak in silc_encode_pem_file in the file
3788 lib/silcutil/silcutil.c.
3790 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Check minor version as well in the SKE. Affected files are
3793 silcd/protocol.c and lib/silcclient/protocol.c.
3795 * Added --identifier option to the server so that an identifier
3796 can be when creating the public key for the server. Affected
3797 file is silcd/silcd.c.
3799 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3800 lib/silccrypt/silcpkcs.c.
3802 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3804 * Register default ciphers and stuff when using -C option with
3805 the server. Affected file sildc/silcd.c.
3807 * Put back the servers public key filename format, it is better
3808 than the new one. For now, the client keys are saved with the
3809 new filename format. The affected file silc/client_ops.c.
3811 * Implemented the Cipher API for the rest of the ciphers that
3812 did not implement it or implemented it the wrong way.
3814 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3816 * Register default ciphers and stuff when using the -S option
3817 in the client. Affected file silc/silc.c. Same also when
3818 creating new key pair with -C option.
3820 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3822 * Fixed the silc_verify_public_key client operation function to
3823 save the public keys differently. The fingerprint is now
3824 used as filename and not the hostname. This way also the
3825 client keys are saved uniquely and not with hostnames. The
3826 affected file is silc/client_ops.c.
3828 * Trimmed the silc_hash_fingerprint function to remove extra
3829 whitespaces from the end of the fingerprint. The affected
3830 file is lib/silccrypt/silchash.c.
3834 * Added silc_cipher_register_default function to register all
3835 default ciphers. It can be used when configuration files
3836 does not exist and the application does not want any specific
3837 ciphers in any specific order.
3839 The SilcDList is now used as silc_cipher_list dynamically
3840 allocated cipher list. Removed the static list all together
3841 and now all ciphers must be allocated to the dynamic list.
3842 The silc_cipher_alloc routine was changed to check only the
3845 All silc_cipher_* routines that used to return int returns
3848 The affected files lib/silccrypt/silccrypt.[ch].
3850 * The same thing was done to silc_hash_* as for silc_cipher_*
3851 routines. Affected files lib/silccrypt/silchash.[ch].
3853 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3854 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3855 Added also silc_pkcs_[un]register[_default] functions.
3856 Removed the data_context from the PKCS API.
3858 * Added silc_hmac_register_default function to register default
3859 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3860 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3861 to unregister all hmacs at once.
3863 * Register the default ciphers, hash functions, PKCSs and HMACs
3864 if client's configuration file does not exist. The affected
3867 * The client did not load the hash functions from the SIM
3868 modules at all. Added support for this. Affected file is
3869 silc/clientconfig.c.
3871 * When decoding public key with silc_pkcs_public_key_decode, check
3872 the supported algorithm only if PKCS are registered. Affected
3873 file lib/silccrypt/silcpkcs.c. The same was done with the
3874 silc_pkcs_private_key_decode.
3876 * Fixed the SILC List routines to keep the list always in order.
3877 It used to change the list's order when traversing the list but
3878 not it preserves the order. Affected file lib/trq/silclist.h.
3880 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * Added the client library to use the SilcSocketConnection's
3883 reference counter (by silc_socket_dup) to prevent the bug that
3884 the socket object may be freed underneath async operation.
3886 * The name resolv library checking fixes in the configure.in.pre.
3889 * Created new version of the protocol drafts for future
3890 development. The -03 drafts are the ones that will be changed
3891 in the trunk now and the -02 will remain as they are.
3893 * Send list of CUMODE notifys to the router when announcing
3894 the channel users to the router. Affected file silcd/server.c.
3895 If the router receiving channel founder CUMODE for a channel
3896 that already has channel founder it will send CUMODE notify
3897 to the sender to remove the channel founder rights from the
3898 announced client. Affected file silcd/packet_receive.c.
3900 * The CUMODE notify may now use Server ID as well as the entity
3901 who changes the mode. Updated protocool specs.
3903 * Updated INSTALL and README files.
3905 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3907 * New web pages in the http://silc.pspt.fi. The pages was
3912 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3914 * Implemented the [DenyConnectin] config section in the server.
3915 Added silc_server_config_denied_conn to check whether incoming
3916 connection is denied. Affected file silcd/serverconfig.[ch].
3918 * Do not check the ports when checking the incoming configuration
3919 data if the port is 0, meaning any. Affected file is
3920 silcd/serverconfig.c.
3922 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3924 * Fixed buffer overflow in silc_string_compare in the file
3925 lib/silcutil/silcutil.c.
3927 * Fixed double free in silc_server_command_leave in the file
3930 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * Fixed the version checking in the server. Affected file is
3935 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3937 * Fixed the configuration data fetching when accepting new
3938 connections in the server. Affected file silcd/server.c.
3940 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3942 * Added `sender_entry' argument to the function
3943 silc_server_packet_relay_to_channel so that we can check
3944 whether some destination actually belongs to the same route
3945 the sender belongs (ie, we must not resend the packet to the
3946 sender). Affected file silcd/packet_send.[ch].
3948 * Added `servername' field to the SilcClientEntry in the server
3949 to hold the name of the server where client is from. Affected
3950 file is silcd/idlist.h.
3952 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3954 * Moved the channel message encrypting in the router betwen
3955 router connections from silc_server_channel_message to the
3956 silc_server_packet_relay_to_channel since we want to check
3957 whether we have anybody channel before encrypting anything.
3958 Affected files silcd/packet_[receive/send].c.
3960 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3962 * Fixed the [AdminConnection] server config section to support
3963 multiple entries. Affected file silcd/serverconfig.c.
3965 * Added support into the server to check the validity of the
3966 incoming connection before executing any KE or authentication
3969 * The connection configuration is now saved to the KE and
3970 connection auth protocol contexts and not fetched anymore in
3971 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3973 * The local hosts listenning address and port is also resolved
3974 now when starting the server. We want to have the socket object
3975 to include the real address and port for the listener. Added
3976 new function silc_net_check_local_by_sock into the files
3977 lib/silcutil/silcnet.[ch].
3979 * Fixed a broadcast bug in server -> do not broadcast if we
3982 * Fixed a routing bug. Do not route broadcast packets ever.
3983 Broadcast packets must be processed always and not routed since
3984 they may be destined to some other host than yourself and thus
3985 would get routed without no good reason. Affected file is
3988 * Added function silc_server_config_is_primary_route to check
3989 whether primary router connection has been configured (a router
3990 configuration that we are initiating). If there is not, we
3991 will assume that there is only two routers in the SILC network
3992 and we will use the incoming router connection as our primary
3993 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3995 * Changed the order of the broadcasting. Broadcast _after_ the
3996 packet has been processed not before. Affected file is
3999 * Fixed a [ClientConnection] parsing bug. The port was never
4000 parsed correctly thus resulting to port 0. Affected file
4001 silcd/serverconfig.c.
4003 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4004 argument and did not set the broadcast packet flag. Affected
4005 file silcd/packet_send.c. Fixed same bug in the function
4006 silc_server_send_notify as well.
4008 * If we receive NEW_ID packet for our own ID in the server, ignore
4011 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * Removed the nickname from the Private Message Payload.
4016 Updated the code and the protocol specs.
4018 * Updated protocol specs for submitting to the IETF.
4020 * Tweaked the Random Number Generator a bit. Affected file
4021 lib/silccrypt/silcrng.c. Exported a new function
4022 silc_rng_[global]_add_noise which can be used to add more
4025 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Do not parse packets with different timeout when protocol
4028 is active -> may cause problem with rekey. Affected file
4031 * When server receives signoff notify it must not create
4032 new channel key if the client is on any channels since the
4033 sender of the signoff notify will create it.
4035 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4037 * Added printing of error messages during SKE protocol from the
4038 failure packet sent by server during SKE. Affected file
4041 * Removed the client's failure_callback handling with timeout
4042 and handle it immediately when received.
4044 * The SKE library returned wrong type in SUCCESS and FAILURE
4045 packets. They must be 32 bit MSB not 16 bit MSB.
4047 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4049 * Ok, rewrote the logic of the re-key and now it seems to work.
4050 I tested it on high traffic with frequent re-keys without
4051 problems. Added hmac_receive (and renamed hmac to hmac_send)
4052 in SilcClientConnection in lib/silcclient/client.h and
4053 in SilcIDListData in silcd/idlist.h. Also, removed the
4054 SilcPacketParserContext's cipher and hmac fields as they are
4055 not needed anymore and actually caused some problems when
4056 the ciphers and hmac's changed underneath the packet parser.
4058 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4060 * If re-key protocol is active then process the incoming packets
4061 synchronously since we must assure that icoming packets encrypted
4062 with the old key is processed before the new keys is set to
4063 use. This is true other packets than for REKEY packets.
4064 Affected file silcd/server.c. The same was done to client library
4065 as well, affected file lib/silcclient/client.c.
4067 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * Fixed bug in client and server to accept the force send if
4070 the packet is send from silc_[server/client]_packet_process
4071 function. Otherwise the packets are never delivered, oops.
4073 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4075 * Disable force sending of packets when REKEY protocol is active.
4076 We must assure that no packet is sent directly when rekey is
4077 performed. All packets must be sent through packet queue.
4078 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4079 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4080 function is silc_[server/client]_packet_send_real to check
4083 * Replaced the SIM paths from example config files to
4084 /usr/local/modules. Also, make install creates now
4085 /usr/local/silc/logs directory to hold all the SILC server
4088 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4090 * Made the configure.in.pre work on Solaris. Patch by salo.

4097 * Fixed the make install.
4099 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4101 * When MAC computation fails the silc_packet_decrypt returned 0
4102 even though it was supposed to return -1. Fixed this. The
4103 affected file is lib/silccore/silcpacket.c.
4105 * Do not replace the config files in /etc/silc (in make install)
4106 if they already exist. Affected file ./Makefile.am.
4108 * Do not send re-key packets immediately but through packet queue.
4109 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4111 * Changed silc_net_check_host_by_sock to return FALSE if the
4112 IP/DNS could not be resolved. Though, it returns the IP address
4113 now even if it could not resolve it (but returns also FALSE).
4114 Affected file lib/silcutil/silcnet.[ch].
4116 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4118 * Added silc_pkcs_decode_identifier to decode the public key's
4119 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4120 Added also silc_pkcs_free_identifier. Added also new context
4121 SilcPublicKeyIdentifier.
4123 * Added -S option to the silc client. It is used to dump the
4124 contents of the specified public key file.
4126 * Changed the PKCS api to return the public key length when
4127 setting the public key.
4129 * Fixed a fatal bug in the public and private key file loading.
4130 Affected file lib/silccrypt/silcpkcs.c.
4132 * Execute the packet parsing for client with zero (0) timeout
4133 if the protocol is active. Affected file silcd/server.c.
4135 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4137 * Made the key generation options to the silcd program. Added
4138 -C option, equivalent to client's option.
4140 * Added new [ServerKeys] config section to the server. It
4141 configures the server's public and private key.
4143 * Defined generic Public Key Payload into the protocol
4144 specification to send specific type of public keys and
4147 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4148 public key or certificate.
4150 * Implemented the GETKEY command to the server and to the
4151 client library and on user interface.
4153 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

4184 SilcClientConnection structure; not needed. Affected file is
4185 lib/silcclient/client.h.
4189 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4191 * Do not ask whether user wants to use the negotiated private key
4192 for private messages, just use it. Affected file is
4193 silc/local_command.c.
4195 * Added `send_enc_key' and `enc_key_len' fields to the
4196 SilcIDListData structure since they are needed in the re-key

4216 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4217 int64 of at least the xintXX size. If void * is less that 4
4218 bytes uint32 * will be used. Defined bool as boolean.
4220 * Changed _ALL_ unsigned long and unsigned int to uint32,
4221 unsgined short to uint16 in the source tree.
4223 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4224 not handle clients that has entry->data.registered == FALSE.
4225 They are not in the network anymore. Affected file is
4228 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4230 * Implemented the sending of the SERVER_SIGNOFF notify in the

4246 if the deleting was successful. Affected file silcd/idlist.[ch].
4248 * Added support for public key authentication in the connection
4249 authentication protocol in the client library. Affected file
4250 lib/silcclient/protocol.c.
4252 * Changed the server's silc_idlist_get_clients_by_* interface
4253 to support already allocated array so that new entries may be

4255 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4256 and command replies.
4258 * All command reply functions in the server now calls the
4259 pending command callback even if error occured. This way the
4260 error will be delivered to the client as well. Affected files
4261 silcd/command.c and silcd/command_reply.c.
4263 * Fixed INFO command to return local server's info if no server
4264 was provided. Affected file lib/silcclient/command.c.
4266 * Removed RESTART command for good. Updated the code and the
4269 * Rewrote parts of the task system. It is a bit simpler now.
4270 Removed unsued task priorities. The affected files are
4271 lib/silcutil/silctask.[ch].
4273 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4275 * Moved the USERS printing from the library to the application.
4276 Affected files lib/silcclient/command.c and silc/client_ops.c.
4278 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4282 * Added channel key re-key support. The re-key is perfomed
4283 only by the router and is done once in an hour. Added `rekey'
4284 field to the SilcChannelEntry in the server. Affected files
4285 silcd/server.c and silcd/idlist.h.
4287 * Added silc_task_unregister_by_context into the file
4288 lib/silcutil/silctask.[ch].
4290 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4292 * Added SILC_UMODE_GONE mode to indicate when the client is not
4293 present in the SILC network. Added also support to the local
4294 command AWAY that will set this mode. Added support of showing
4295 "xxx is gone" in WHOIS command. The USERS command shows the
4296 gone status as well.
4298 * Fixed setting server and router operator privileges in the
4299 server's UMODE command. Affected file silcd/command.c.
4301 * Merged the SKE KE1 and KE2 payloads into one payload. The
4302 new KE payload is equivalent to the old KE2 payload.
4304 Cleaned up the SKE Start Payload parsing. It now uses the
4305 simple buffer unformatting to do the parsing. A lot faster
4308 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4309 to the SKE that is used to indicate whether both of the SKE
4310 parties should perform authentication. By default only the
4311 responder performs authentication. By setting this flag also
4312 the initiator must do authentication. By default it is unset
4313 since in normal SKE case, client to server connection, only
4314 the responder should do authentication. When doing SKE between
4315 two clients both should perform authentication. Updated the
4316 code and the protocol specs.
4318 * A little fix to IDENTIFY command in the server. Search the
4319 client first by hash not nickname. Affected file is
4322 * Fixed the silc_client_close_connection to support closing
4323 the client to client connections wihtout deleting too much
4324 data. Affected file lib/silcclient/client.c.
4326 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4327 are received if protocol used to be active but is not anymore
4328 the application would crash due to NULL pointer dereference.
4329 Affected files silcd/server.c and lib/silcclient/client.c.
4331 * Added `hash' field to the SilcClientConnection to include
4332 the hash function negotiated in the SKE protocol.
4334 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4335 to set the channel founder authentication data. A client can
4336 claim the founder rights later by providing the authentication
4337 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4338 This way the channel founder can regain the channel founder
4339 privileges even it is left the channel. This works only on
4340 local server and the client must be connected to the same
4341 server to be able to regain the founder rights. Updated the
4342 protocol specs accordingly.
4344 Added support to the CMODE command in the client to set the
4345 founder auth data. Read the README to see how to set it.
4347 Added support to the CUMODE command to claim the founder
4348 rights. Read the README to see how to do it.
4350 Added support for the founder authentication to the Channel
4351 Entry in the server. Affected file silcd/idlist.h.
4353 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4354 server's CMODE command. Affected file silcd/command.c.
4356 * Added the following new functions into lib/silccore/silcauth.[ch]:
4357 silc_auth_get_method and silc_auth_get_data.
4359 * The server now saves the remote hosts public key to the
4360 SilcIDListData pointer. Affected file silcd/protocol.c.
4362 * The normal server now does not remove the channel entry from
4363 the cache if the founder authentication data is set. It used
4364 to remove it if the founder was the last one on the channel on
4365 the server and left the channel. The auth data is saved and
4366 if the channel is re-joined later the old entry is used with
4367 the old auth data. Affected files silcd/command_reply.c and
4370 * Removed the `pkcs' field from the SilcIDListData structure
4371 in the server; it is not used. Affected file silcd/idlist.h.
4373 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4375 * Fixed packet processing on slow links. Partial packets were
4376 never re-processed because the incoming data buffer was cleared
4377 by the application. Application must not directly clear the
4378 sock->inbuf, the packet processing routines handle it. Fixed
4379 this in client library and in server.
4381 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * Fixed the WHOIS and IDENTIFY send reply function to really
4384 check whether to send list or just one entry. Affected file
4387 * Cleaned up the LEAVE command's channel key distribution. The
4388 affected file silcd/command.c.
4390 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4391 can enforce the channel mode as well. In that case the ID
4392 includes the ID of the server. The code now enforces the
4393 mode change if the router have different mode than the server.
4395 * The notify client operation with CMODE_CHANGE notify can now
4396 return NULL client_entry pointer if the CMODE was not changed
4397 by client. Application must check for this.
4399 * Added <Server ID> argument to INFO command to support server
4400 info fetching by Server ID.
4402 * Added silc_server_announce_get_channel_users to get assembled
4403 packets of channel users of the specified channel. Affected
4404 file silcd/server.[ch].
4406 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4407 was freed underneath the ID Cache.
4409 * Re-announce clients when the server received CHANNEL_CHANGE
4410 notify from the router. Affected file silcd/packet_send.c.
4412 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4414 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4415 crashed since it did not handle the fact that there is no cipher
4416 called "3" and didn't check the error condition. Now fixed.
4418 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4419 flag. It can be used to send message requests.
4421 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4423 * Implemented the RESTART command in the client.
4425 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4426 notice type messages. Added notice printing to the user
4429 * The channel keys are not re-generated if the channel's mode
4430 is PRIVKEY, ie private key on the channel exists. Affected
4431 files silcd/server.c and silcd/command.c.
4433 * Fixed a little bug in channel message delivery when channel
4434 private keys are set in the server. Affected file is
4435 silcd/packet_send.c.
4437 * Changed the setting on channel->on_channel = TRUE from the
4438 silc_client_save_channel_key to the JOIN command reply. The
4439 key payload is not received if the private channel key is set.
4440 Affected file lib/silcclient/command_reply.c and the
4441 lib/silcclient/client_channel.c.
4443 * When the CMODE_CHANGE notify is sent and the channel private
4444 key mode is removed the channel key must be re-generated in
4445 other cells as well. Added this support for the router in the
4446 silcd/packet_receive.c.
4448 * Added new local command NOTICE to send notice message on
4449 channel. Affected file silc/local_command.[ch].
4451 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4453 * Added new local command ME to the client. It is used to send
4454 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4455 some action. Affected file silc/local_command.[ch].
4457 * Changed channel_message and private_message client operations
4458 to deliver the message flags to the application. Added also
4459 the `flags' arguments to the silc_client_send_channel_message
4460 and silc_client_send_private_message functions. Affected file
4463 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4465 * Redefined the Private Message Payload to support private message
4466 keys and to support the new private message flags. Updated
4467 the protocol specs. Flags makes it possible to have for example
4468 CTCP style messages.
4470 * Added new type SilcPrivateMessagePayload and defined an API
4471 for it in the lib/silcclient/silcprivate.[ch].
4473 * Tested private message private keys successfully. Tested the
4474 private message key set, unset and list commands with the new
4477 * Redefined the Channel Message Payload to include the channel
4478 message flags (equal with private message flags) to support
4479 for example CTCP style messages.
4481 * Defined some of the message (for channel and private message)
4482 flags. Updated the protocol specs and added the flags to the
4483 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4485 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4487 * Added SilcKeyAgreementStatus type to the key agreement routines
4488 to indicate the current status and error if one occured.
4489 The status types are defined in the lib/silcclient/silcapi.h.
4491 * Added new local command KEY that is used to set and unset private
4492 keys for channels, set and unset private keys for private messages
4493 with remote clients and to send key agreement requests and
4494 negotiate the key agreement protocol with remote client. The
4495 key agreement is supported only to negotiate private message keys,
4496 it currently cannot be used to negotiate private keys for channels,
4497 as it is not convenient for that purpose.
4499 * Fixed a minor pending callback setting bug in the function
4500 silc_client_get_client_by_id_resolve, now the function works.
4501 Affected file lib/silcclient/idlist.c.
4503 * Added function silc_net_get_local_port to get local bound
4504 port by socket. Added to lib/silcutil/silcnet.[ch].
4506 * Added `sockets' and `sockets_count' fields to the SilcClient
4507 object. They hold the sockets of the listenning sockets in
4508 the client. Listenning sockets may be for example the key
4509 agreement server. Affected file lib/silcclient/client.[ch].
4510 Added functions the silc_client_add_socket and the
4511 silc_client_del_socket. They are exported to the application
4514 * Added ~./silc/clientkeys to support other client's public keys.
4516 * Renamed verify_server_key client operation to verify_public_key
4517 and added one argument to indicate the type of the connection
4518 (server, client etc.).
4520 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4522 * Added silc_server_connection_auth_request to handle the
4523 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4524 silcd/packet_receive.[ch].
4526 * Added silc_server_send_connection_auth_request into the
4527 silcd/packet_send.c to send the connection auth request packet.
4529 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4532 * Fixed the public key authentication in responder side in the
4533 server. The `auth_data' pointer includes the SilcPublicKey
4534 not the path to the public key. Affected file silcd/protocol.c.
4536 * Implemented the public key authentication in the initiator side
4537 in the server. Affected file silcd/protocol.c.
4539 * Removed the [RedirectClient] config section from the server
4540 configuration. Is not needed and I don't want to implement it.
4542 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4544 * Cleaned up the CMODE command in the server. It now works
4545 correctly and supports all the modes defined in the protocol.
4546 Affected file is silcd/command.c.
4548 * Added `hmac_name' field to the SilcChannelEntry in the server
4549 to hold the default HMAC of the channel. It can be set when
4550 creating the channel (with JOIN command). Affected files
4553 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4554 type to indicate the change of the current cipher and hmac
4555 on the channel. Client can safely ignore the <cipher> argument
4556 (if it chooses to do so) since the CHANNEL_KEY packet will
4557 force the channel key change anyway. The <hmac> argument is
4558 important since the client is responsible of setting the new
4559 HMAC and the hmac key into use.
4561 * Fixed the CMODE command in the client library as well.
4563 * Tested CMODE command in router environment successfully.
4565 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4567 * Show the version of the remote client (or server) when connecting
4568 to the server. It is logged to the log file. Affected file
4569 is silcd/protocol.c.
4571 * Fixed the KILLED notify handling in the client library. The
4572 client must be removed from all channels when receiving the
4575 Also, do not remove the client entry when giving the KILL
4576 command but when the KILLED notify is received.
4578 * Removed silc_idlist_find_client_by_nickname from the server.
4579 Not needed anymore. Affected files silcd/idlist.[ch].
4581 * Implemented the CHANNEL_CHANGE notify type handling to the
4582 server. Affected file silcd/server.c.
4586 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4588 * Added silc_server_send_notify_invite to send the INVITE
4589 notify between routers.
4591 * Implemented the INVITE command correctly to the server.
4593 * Implemented the INVITE notify type handling in the server.
4595 * Implemented the INVITE command to the client library and on the
4598 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Added function silc_server_get_client_resolve to find the
4601 client entry by ID from all ID lists and then resolve it
4602 (using WHOIS) if it cannot be found. Affected file is
4605 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4607 * Implemented the BAN command to the client library.
4609 * The JOIN command in the server now checks the invite list
4612 * Changed the silc_command_reply_payload_encode_va and the
4613 silc_command_payload_encode_va to support that if argument is
4614 NULL it ignores and checks the next argument. Affected file
4615 lib/silccore/silccommand.c.
4617 * Added silc_server_send_notify_ban to send the BAN notify
4618 type between routers.
4620 * Chaned the silc_notify_payload_encode to support that if
4621 argument is NULL it ignores and checks the next argument.
4622 Affected file lib/silccore/silcnotify.c.
4624 * Tested ban lists in router environment successfully.
4626 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4628 * Implemented BAN command to the server, in silcd/command.[ch].
4630 * Removed the BAN and INVITE_LIST modes from the CMODE command
4633 * Added function silc_string_match to regex match two strings.
4634 Affected files lib/silcutil/silcutil.[ch].
4636 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Redefined parts of the SilcChannelEntry in the server to support
4639 the new ban and invite lists.
4641 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4643 * Redefined the INVITE command. The same command can be used to
4644 invite individuals to the channel but also to manage the invite
4645 list of the channel (to add to and remove from the invite list).
4646 Updated the protocol specs.
4648 * Added new command SILC_COMMAND_BAN that can be used to manage
4649 the ban list of the channel. Updated the protocol specs.
4651 * Removed the channel modes: the SILC_CMODE_BAN and the
4652 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4653 in the CMODE command. The equivalent features are now available
4654 using INVITE and BAN commands. Updated the protocol specs.
4656 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4657 in the network about change in the current ban list. The notify
4658 type is not used by the client.
4660 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4661 support the invite lists.
4663 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4665 * Added new function silc_string_regexify that converts string
4666 including wildcard characters into regex string that can
4667 be used by the GNU regex library. Added into the file
4668 lib/silcutil/silcutil.[ch].
4670 Added silc_string_regex_combine to combine to regex strings
4671 into one so that they can be used as one regex string by
4672 the GNU regex library. Added into the file
4673 lib/silcutil/silcutil.[ch].
4675 Added silc_string_regex_match to match two strings. It returns
4676 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4678 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4680 * Imported GNU regex to the soruce tree into lib/contrib.
4681 Fixed some compiler warning from the regex.c.
4683 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4685 * Fixed MOTD command in the server to work in router environment.
4687 * Fixed the MOTD command in the client library to support
4688 the server argument in the command.
4690 * Added `nickname_len' argument to the silc_idlist_add_client
4691 in the server, as the `nickname' argument may be binary data
4694 * Added silc_idlist_get_channels to return all channels from
4697 * Implemented LIST command to the server. Affected file is
4700 * Implemented the LIST command to the client library and on the
4703 * Added [<user count>] argument to the LIST command reply.
4704 With private channels the user count is not shown.
4706 * Updated TODO and README.
4708 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4710 * The client entry's data.registered must be TRUE even with
4711 global client entry on global client list. The data.registered
4712 is used to check whether the client is anymore in the network,
4713 for example with WHOWAS command so it must be valid.
4715 * Fixed the WHOWAS command in the server. It now actually works
4716 in router environment. Added function into silcd/command_reply.c
4717 silc_server_command_reply_whowas_save.
4719 * Added silc_idlist_purge function to the silcd/idlist.c
4720 to periodically purge the ID Cache.
4722 * Fixed INFO command in the server. It works now in router
4723 environment. Added <server name> argument to the INFO command
4724 reply. Updated the protocol specs.
4726 * Fixed minor bug in silc_idcache_purge to not purge if the
4727 expire value is zero.
4729 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4730 they were buggy because of the WHOWAS information.
4732 * Fixed local command MSG to handle the async resolving of
4733 the remote client properly. It used to fail the first MSG.
4734 Affected file silc/local_command.c.
4736 * Added `data_len' field to SilcIDCache context.
4738 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Update TODO. Todo in commands in the server.
4742 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4744 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4745 used by routers as broadcast packet to inform other routers
4746 about the changed user mode.
4748 Implemented the notify handling in the server. Affected file is
4749 silcd/packet_receive.c. Added the function
4750 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4752 * Added new generic Channel Payload and deprecated the New Channel
4753 Payload. The New Channel Payload is now the generic Channel
4756 * Added new argument `mode' to the silc_server_send_new_channel
4757 as it is required in the Channel Payload now.
4759 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4760 and created a new and real SilChannelPayload to represent the
4761 new generic Channel Payload. Implemented the encode/decode
4762 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4764 * Added silc_server_get_client_channel_list to return the list
4765 of channels the client has joined for WHOIS command reply.
4766 Affected file silcd/server.[ch].
4768 * Implemented the channel list sending in the WHOIS command reply
4769 in server and in the client.
4771 Implemented the channel list displaying on the user interface
4772 as well. Affected file silc/client_ops.c.
4774 * Added silc_channel_payload_parse_list to parse list of Channel
4775 Payloads. It returns SilcDList list of SilcChannelPayloads.
4776 Client for example can use this function to parse the list of
4777 channels it receives in the WHOIS command reply. The caller
4778 must free the list by calling silc_channel_payload_list_free.
4779 Affected files lib/silccore/silcchannel.[ch].
4781 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4783 * Added one new argument <user mode> to the WHOIS command reply
4784 to return the mode of the user in SILC. Updated the protocol
4787 Implemented it to the server and client.
4789 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4791 * Fixed the mode printing on the user interface on joining.
4792 Affected file silc/client_ops.c.
4794 * Implemented the UMODE command and user modes in general to the
4795 client library and to the user interface.
4797 * Implemented the UMODE command to the server.
4799 * The server now sends UNKNOWN_COMMAND error status if client sends
4800 unknown command. Affected file silcd/command.c.
4802 * All server commands now handle the command identifier the right
4803 way when sending the command reply to the client. The client can
4804 use to identify the command replies with the identifier.
4806 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4808 * Added silc_server_get_client_route to resolve the route to
4809 the client indicated by the client ID. Affected file is
4812 * Added silc_server_relay_packet as general function to relay
4813 packet to arbitrary destination. This deprecates functions
4814 like _send_private_message_key, _relay_notify etc. Affected
4815 file is silcd/packet_send.[ch].
4817 Removed silc_server_send_key_agreement,
4818 silc_server_send_private_message_key and
4819 silc_server_packet_relay_notify functions from the file
4820 silcd/packet_send.[ch].
4824 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4825 server. Affected file silcd/packet_receive.[ch].
4827 * Implemented the KILL command to the client. Implemented the
4828 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4829 Affected files lib/silcclient/command[_reply].c and
4830 lib/silcclient/client_notify.c. Implemented the KILL notify
4831 printing in the user inteface.
4833 * Fixed a lot silc_parse_nick memory leaks from the client
4834 library in the file lib/silcclient/command.c.
4836 * Changed the silc_server_send_notify_on_channels's `sender'
4837 argument from SilcSocketConnection to SilcClientEntry to
4838 check the sender as entry and not as connection object and not
4839 to send to the client provided as argument. The affected file
4840 is silcd/packet_send.[ch].
4842 * The notify packets that are destined directly to the client used
4843 to not to be processed by the server. Now changed that and the
4844 server processes all notify packets. After relaying the packet
4845 to the client the notify packet is processed in the server.
4847 * The silc_server_free_client_data now checks whether there is
4848 pending outgoing traffic for the client and purges the data to
4849 the network before removing the client entry.
4851 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4853 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4854 an client is killed from the SILC Network. Updated the protocol
4857 Added new function silc_server_send_notify_killed to the
4858 silcd/packet_send.[ch].
4860 * Added function silc_server_packet_relay_notify to relay notify
4861 packets that are destined directly to a client. In this case
4862 the server does not process the notify packets but merely relays
4863 it to the client. Affected file silcd/packet_send.[ch].
4865 Added also silc_server_packet_process_relay_notify to check
4866 whereto relay the notify. Affected file is
4867 silcd/packet_receive.[ch].
4869 * Implemented the KILL command to the server.
4873 * Added the backup schema desgined last fall to the protocol
4874 specs for everyone to see. The specification is in the
4875 *-spec-xx.txt draft and the packet type definitions for the
4876 backup routers is in *-pp-xx.txt draft. Thusly, added also
4877 new packet type SILC_PACKET_CELL_ROUTERS.
4879 * A big security problem in the implementation discovered. The
4880 signoff of an client did not cause new channel key generation
4881 which it of course should've done. The channel keys must be
4882 always re-generated when client leaves (or signoffs) the channel.
4883 The silc_server_remove_from_channels funtion now handles
4884 the channel key re-generation.
4886 * Added `sender' argument to the silc_server_send_notify_on_channels
4887 to not to send the client provided as argument. Affected file
4888 silcd/packet_send.[ch].
4890 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Implemented OPER and SILCOPER commands into the server and
4895 * Added silc_auth_verify and silc_auth_verify_data to verify
4896 the authentication directly from the authentication payload.
4897 It supports verifying both passphrase and public key based
4898 authentication. Affected file lib/silccore/silcauth.[ch].
4900 * Added `hash' field to the SilcIDListData structure. It is the
4901 hash negotiated in the SKE protocol. Affected file is
4904 * Slight redesigning of the SilcAuthPayload handling routines.
4905 Do not send SilcPKCS but SilcPublicKey as argument.
4907 * Implemented the public key authentication support to the
4908 serverconfig. The public key is loaded from the provided path
4909 and saved as authentication data to void * pointer. Thus,
4910 changed the unsigned char *auth_data to void *auth_data;
4912 * Fixed SHUTDOWN command to send the reply before the server
4913 is shutdown. :) Affected file silcd/command.c.
4915 * Fixed fatal bug in CONNECT command. The hostname was invalid
4916 memory and server crashed. Affected file silcd/command.c.
4918 * Fixed fatal bug in CLOSE command. The server_entry became
4919 invalid but was referenced later in the command. Affected file
4922 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4924 * Fixed fatal bug in failure packet handling. Server ignored
4925 the failure and thus crashed when it came.
4929 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4931 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4932 that the command may be executed only once in (about) 2 seconds.
4933 The old SILC_CF_LAG flag is same but allows command bursts up
4934 to five before limiting.
4936 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4937 server code. Various commands now includes the CF_LAG_STRICT
4938 flag to disallow any kind of miss-use of the command.
4940 * Fixed the silc_buffer_unformat to not to allocate any data
4941 if the length of the data is zero. It used to allocate the
4942 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4944 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4946 * Changed the format of AdminConnection configuration section
4947 in the server. Added username of the admin to the format.
4948 Affected files silcd/serverconfig.[ch].
4950 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4951 to return admin configuration data by host, username and/or
4954 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4956 * Implemented WHOWAS command to the server. Added the functions:
4958 silc_server_command_whowas_parse,
4959 silc_server_command_whowas_send_reply,
4960 silc_server_command_whowas_from_client and
4961 silc_server_command_whowas_from_server
4963 * Added <Client ID> argument to the WHOWAS command reply. Updated
4964 the protocol specs accordingly.
4966 * Implemented WHOWAS command and command_reply to the client
4969 Implemented the WHOWAS printing on the user interface.
4971 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4973 * Added new argument to the WHOWAS command reply, the real name.
4974 It is an optional argument. Updated the protocol specs.
4976 * Added SilcIDCacheDestructor callback that is registered when
4977 the SilcIDCache is allocated. The callback is called when
4978 an cache entry in the ID Cache expires, or is purged from the
4979 cache. Added into lib/silccore/idcache.[ch].
4981 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4982 to destruct the client entries when the cache entry expires.
4983 Other ID Cache's in server and in the client library ignores
4986 * If the ID Cache entry's `expire' field is zero then the entry
4987 never expires. Added boolean `expire' argument to the
4988 silc_idcache_add function in the lib/silccore/idcache.[ch].
4989 If it is TRUE the default expiry value is used.
4991 * Added silc_server_free_client_data_timeout that is registered
4992 when client disconnects. By default for 5 minutes we preserve
4993 the client entry for history - for WHOWAS command.
4995 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * Added support to the server to enforce that commands are not
4998 executed more than once in 2 seconds. If server receives
4999 commands from client more frequently, timeout is registered
5000 to process the commands. Affected file silcd/command.c.
5001 Added new function silc_server_command_process_timeout.
5003 * Changed NICK_NOTIFY handling in client library to check that
5004 if the client's nickname was changed, so there is no need to
5005 resolve anything from the server.
5007 * Removed error printing from the WHOIS and IDENTIFY commands.
5008 If error occurs then it is ignored silently in the client library.
5009 The application, however, may map the received error to
5010 human readable error string. The application currently maps
5011 the NO_SUCH_NICKNAME error to string.
5013 * Made the command status message public to the application. Moved
5014 them from lib/silcclient/command_reply.c to
5015 lib/silcclient/command_reply.h. The application can map the
5016 received command status to the string with the
5017 silc_client_command_status_message function.
5019 * Added check to the server to check that client's ID is same
5020 as the Source ID in the packet the client sent. They must
5023 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5025 * Added dist-bzip hook to the Makefile.am to make bzip2
5026 compressed distributions.
5028 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Server now enforces the maximum length for the nickname and
5031 the channel as protocol specification dictates. 128 bytes for
5032 nickname and 256 bytes for channel name.
5034 * Moved the WHOIS printing to the application. The client libary
5035 does not print out the WHOIS information anymore, the application
5036 must do it. Renamed silc_client_command_reply_whois_print to
5037 the silc_client_command_reply_whois_save.
5039 The client's idle time is also sent to the application now, and
5040 the idle is shown on screen.
5042 * Added silc_client_command_reply_identify_save to save the
5043 received IDENTIFY entries.
5045 * Do not check for channel private keys in message sending and
5046 reception if the channel does not have the PRIVKEY mode set.
5047 Affected file lib/silclient/client_channel.c.
5049 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5052 just surfaced after chaning the JOIN procedure.
5054 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5056 * Added silc_client_get_clients_by_list to get client entries
5057 from Client ID list, that is returned for example by JOIN
5058 and USERS command replies. The application should use this
5059 function for example when JOIN command reply is received to
5060 resolve the clients already on the channel (library does not
5061 do that anymore as USERS command reply is not used in the JOIN
5062 procedure anymore). Affected files lib/silcclient/silcapi.h and
5063 lib/silcclient/idlist.c.
5065 * JOIN command reply and USERS command reply returns now SilcBuffer
5066 pointers instead of unsigned char pointers when returning
5067 the client list and mode list.
5069 * Added <Client ID> argument to the JOIN command reply, mainly
5070 for the server to identify for which client the command was
5071 originally sent. Updated protocol specs accordingly.
5073 * Added SilcDlist private_key pointer to the SilcChannelEntry
5074 in the client to support the channel private keys. Affected
5075 file is lib/silcclient/idlist.h.
5077 * Added SilcChannelPrivateKey argument to the function
5078 silc_client_send_channel_message so that application can choose
5079 to use specific private ke if it wants to. If it is not provided,
5080 the normal channel key is used, unless private keys are set.
5081 In this case the first (key that was added first) is used
5082 as the encryption key.
5084 * Implemented the support for channel private key handling.
5085 Implemented the following functions:
5087 silc_client_add_channel_private_key,
5088 silc_client_del_channel_private_keys,
5089 silc_client_del_channel_private_key,
5090 silc_client_list_channel_private_keys and
5091 silc_client_free_channel_private_keys
5093 Affected file lib/silcclient/client_channel.c.
5095 * Added the support for the private keys in the channel message
5096 sending and encryption and in the message reception and
5097 decryption. Affected funtions are
5098 silc_client_send_channel_message and silc_client_channel_message.
5100 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * Added SKE's key verify callback to the client library's
5103 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5105 * Removed the statement that server (or router) must send USERS
5106 command reply when joining to the channel so that the client
5107 knows who are on the channel. Instead, the client list and
5108 client's mode list is now sent in the JOIN command reply to the
5109 client who joined channel. This is better solution.
5111 * Added function silc_server_get_users_on_channel and function
5112 silc_server_save_users_on_channel to the silcd/server.[ch].
5114 * Removed function silc_server_command_send_users from the
5117 * Do not show topic on the client library anymore. The topic is
5118 sent in the command reply notify to the application and the
5119 application must show the topic now.
5121 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5123 * Added client searching by nickname hash into the IDENTIFY and
5124 WHOIS commands in the server as they were clearly missing from
5125 them. Affected file is silcd/command.c.
5127 * Fixed a bug in private message receiving in the client library.
5128 The remote ID was freed and it wasn't supposed, now it is
5131 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5133 * Minor fix to the channel payload; allocate the data area, as it
5134 needs to be of specific length.
5136 * If the key agreement port is zero then the operating
5137 system will define the bound port. Affected files are
5138 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5140 * Added new function silc_channel_payload_decrypt into the file
5141 lib/silccore/silcchannel.[ch].
5143 * Moved the channel message etc, check from silc_packet_decrypt
5144 to applications. The library calls now a generic
5145 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5146 when the packet is either normal or special. This was done to
5147 allow more wide range of checking that was not allowed when
5148 the code was in library. Now applications can do virtually any
5149 checks to the packet and return to the library the decision how
5150 the packet should be processed. Affected files are
5151 lib/silccore/silcpacket.[ch].
5153 Added silc_server_packet_decrypt_check to the server and
5154 silc_client_packet_decrypt_check to the client library.
5156 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5157 to send with specified source and destination information.
5159 * Channel message delivery between routers was broken after the
5160 channel key distribution was fixed earlier. The channel key
5161 was used be to distributed to other routers as well which is not
5162 allowed by the protocol. Now this is fixed and channel keys
5163 really are cell specific and the channel message delivery between
5164 routers comply with the protocol specification.
5166 * Fixed various commands in server to check also the global list
5167 for the channel entry and not just the local list. The affected
5168 file silcd/command.c.
5170 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5172 * Added assert()s to buffer formatting and unformatting routines
5173 to assert (if --enable-debug) when error occurs. Affected
5174 file: lib/silcutil/silcbuffmt.c.
5176 * Changed to auto-reconnect to check whether the remote host is
5177 router and register the re-connect timeout if it is. It used
5178 to check that whether we are normal server, but router must do
5179 auto-reconnect with another router as well. Affected file
5182 * Removed the [<key len>] option from CMODE command as the cipher
5183 name decides the key length, nowadays. See the defined ciphers
5184 from the protocol specification.
5186 * Added [<hmac>] option to the CMODE command to define the HMAC
5187 for the channel. Added SILC_CMODE_HMAC channel mode.
5189 * Added [<hmac>] option for the JOIN command so that user can
5190 select which HMAC is used to compute the MACs of the channel
5193 * Added Hmac field to the Channel Message Payload. The integrity
5194 of plaintext channel messages are now protected by computing
5195 MAC of the message and attaching the MAC to the payload. The
5196 MAC is encrypted. Now, it is clear that this causes some
5197 overhead to the size of the packet but rationale for this is that
5198 now the receiver can verify whether the channel message decrypted
5199 correctly and also when private keys are set for the channel the
5200 receiver can decrypt the packet with several keys and check from
5201 the MAC which key decrypted the message correctly.
5203 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5204 lib/silccrypt/silccipher.[ch].
5206 * Added silc_hash_len to return the digest length into the
5207 lib/silcrypt/silchash.[ch].
5209 * Rewrote parts of Silc Channel Payload interface in the
5210 lib/silccore/silcchannel.[ch]. The encode function now also
5211 encrypts the packet and parse function decrypts it.
5213 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5215 * Fixed a minor formatting bug in the SKE's key material processing.
5216 It actually might have processed the keys wrong way resulting
5219 * Redefined the mandatory HMAC algorithms and added new algorithms.
5220 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5221 and hmac-md5 truncated to 96 bits. The mandatory is now
5222 hmac-sha1-96. Rest are optional (including the one that used
5223 to be mandatory). Rationale for this is that the truncated HMAC
5224 length is sufficient from security point of view and can actually
5225 make the attack against the HMAC harder. Also, the truncated
5226 HMAC causes less overhead to the packets. See the RFC2104 for
5229 * Added new [hmac] configuration section. The SKE used to use
5230 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5231 is of course wrong. The official names that must be proposed in
5232 the SKE are the ones defined in the protocol specification
5233 (hmac-sha1-96 for example). The user can configure any hmac
5234 using any hash function configured in the [hash] section. At
5235 least, the mandatory must be configured.
5237 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5239 * Added HMAC list to the SKE proposal list. It has now both
5240 hash algorithm list and HMAC list. This makes the protocol
5241 incompatible with previous versions. The SKE now seems to work
5242 the way it is supposed to work, for the first time actually.
5244 * Defined plain Hash algorithms to the protocol specification.
5247 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Implemented support for key agreement packets into the server.
5250 Added functions silc_server_key_agreement and
5251 silc_server_send_key_agreement. Other than these functions,
5252 server has nothing to do with this packet.
5254 * Added support for private message key packets into the server.
5255 Added functions silc_server_private_message_key and
5256 silc_server_send_private_message_key.
5260 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5261 called in the protocol's final callback instead in the END
5262 protocol state. This makes a little more sense and in the same
5263 time in client we can use the same protocol routines for normal
5264 key exchange and to key agreement packet handling as well.
5266 * Added to both client's and server's KE protocol context the
5267 SilcSKEKeyMaterial pointer to save the key material. We will
5268 bring the key material to the protocol's final callback by doing
5269 this. The final callback must free the key material.
5271 * Added SKE's packet_send callback into client's KE protocol
5272 context so that the caller can choose what packet sending function
5273 is used. This way we can use different packet sending when
5274 doing normal SKE when doing key agreement packet handling (in
5275 the key agreement packet handling we do not want to encrypt
5278 * Implemented the responder side of the key agreement routines
5279 in the client. The client can now bind to specified port and
5280 accept incoming key negotiation. The key material is passed
5281 to the application after the protocol is over.
5283 * Implemented the processing of incoming Key Agreement packet
5284 in the client. Added function silc_client_key_agreement to
5287 * Implemented the intiator side of the key agreement routines
5288 in the client. The client can now initiate key agreement with
5289 another remote client. The key material is passed to the
5290 application after the protocol is over.
5292 * Created client_keyagr.c to include all the key agreement
5295 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5296 SILC_TASK_CALLBACK except that it is not static.
5298 * Created client_notify.c and moved the Notify packet handling
5299 from the client.[ch] into that file.
5301 * Created client_prvmsg.c and moved all private message and
5302 private message key routines from the client.[ch] into that file.
5304 * Create client_channel.c and moved all channel message and
5305 channel private key routines from the client.[ch] into that file.
5307 * Changed silc_client_get_client_by_id_resolve to resolve with
5308 WHOIS command instead of IDENTIFY command, in the file
5309 lib/silclient/idlist.c.
5311 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5313 * Implemented the SKE's responder side to the Client library.
5315 * When FAILURE is received to the protocol do not trust it
5316 blindly. Register a timeout to wait whether the remote closes
5317 the connection as it should do it, only after that process the
5318 actual failure. This was changed to both client and server.
5320 * Added client_internal.h to include some of the structures
5321 there instead of client.h in lib/silcclient/.
5323 * Added function silc_task_unregister_by_callback to unregister
5324 timeouts by the callback function.
5326 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5328 * Some "Incomplete WHOIS info" errors has been appearing on the
5329 log files. Took away the entry->userinfo check from WHOIS
5330 reply sending. The entry->userinfo is now " " if client did not
5331 provide one. I thought this was fixed earlier but something
5332 is wrong still. Let's see if the error still appears.
5334 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5336 * Fixed a minor bug in the login when the channel key is
5337 re-generated in the server. It used to generate the key in
5338 wrong order and thus caused problems in the channel traffic.
5340 * Fixed a minor bug in channel key distsribution after
5341 KICK command. The key was not sent to the router even though
5344 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5346 * Added silc_ske_process_key_material_data as generic routine
5347 to process any key material as the SILC protocol dictates. The
5348 function is used by the actual SKE library but can be used by
5349 applications as well. This relates to the private message keys
5350 and the channel private keys since they must be processed the
5351 same way the normal SILC session keys. The protocol dictates
5352 this. Affected files: lib/silcske/silcske.[ch].
5354 Added also silc_ske_free_key_material to free the
5355 SilcSKEKeyMaterial structure.
5357 * Defined silc_cipher_set_key function to set the key for
5358 cipher without using the object's method function. The affected
5359 files: lib/silccrypt/silccipher.[ch].
5361 * Implemented silc silc_client_add_private_message_key,
5362 silc_client_add_private_message_key_ske,
5363 silc_client_del_private_message_key,
5364 silc_client_list_private_message_keys and
5365 silc_client_free_private_message_keys functions in the
5368 Added functions silc_client_send_private_message_key to send
5369 the Private Message Key payload and silc_client_private_message_key
5370 to handle incoming Private Message Key payload.
5372 * Added Cipher field to the Private Message Key payload to set
5373 the cipher to be used. If ignored, the default cipher defined
5374 in the SILC protocol (aes-256-cbc) is used.
5376 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5378 * Removed lib/silcclient/ops.h file.
5380 Redefined parts of the SILC Client Library API. Created new
5381 file silcapi.h that deprecates the ops.h file and defines the
5382 published Client Library API. Defined also private message key
5383 API and channel private key API into the file.
5385 This is the file that the application must include from the
5386 SILC Client Library. Other files need not be included by
5387 the application anymore.
5389 * Added new key_agreement client operation callback and also
5390 defined the Key Agreement library API for the application.
5392 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5395 is used by clients to request key negotiation between another
5396 client in the SILC network. If the negotiation is started it
5397 is performed using the SKE protocol. The result of the
5398 negotiation, the secret key material, can be used for example
5399 as private message key.
5401 Implemented the Key Agreement payload into the files
5402 lib/silccore/silauth.[ch].
5404 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Redefined ciphers for the SILC protocol. Added some new ciphers
5407 and defined the key lengths for the algorithms. Changed the
5408 code accordingly. The default key length is now 256 bits.
5410 * Fixed SKE key distribution function silc_ske_process_key_material
5411 when the key length is more than 128 bits. The default key
5412 length in SILC is now 256 bits.
5414 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5415 to indicate unsupported algorithm.
5417 * Renamed rijndael.c to aes.c and all functions as well.
5419 * Fixed a long standing channel key setting bug in client library.
5420 Weird that it has never surfaced before.
5422 * Fixed bug in channel deletion. If the entire channel is removed
5423 then it must also delete the references of the channel entry
5424 from the client's channel list as the client's channel entry and
5425 the channel's client entry share same memory.
5427 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5429 * Implemented CONNECT and SHUTDOWN commands in the client.
5431 * Implemented CLOSE command to the client.
5433 * Added the function silc_idlist_find_server_by_name into the
5434 files silcd/idlist.[ch].
5436 Added the function silc_idlist_find_server_by_conn into the
5437 files silcd/idlist.[ch].
5439 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5441 * DIE command was renamed to SHUTDOWN. Updated the both code
5444 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5445 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5447 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5450 * Added function silc_server_create_connection function to create
5451 connection to remote router. My server implementation actually
5452 does not allow router to connect to normal server (it expects
5453 that normal server always initiates the connection to the router)
5454 so the CONNECT command is only good for connecting to another
5457 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5459 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5460 or some other client was kicked from the channel.
5462 Implemented the handling of the notify type to both client
5465 Implemented silc_server_send_notify_kicked to send the KICKED
5466 notify. It is used to send it to the server's primary router.
5468 * Implemented the KICK command into server and client.
5470 * Added `query' argument to the silc_idlist_get_client function
5471 to indicate whether to query the client from server or not if
5474 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5475 to indicate that the client is not channel founder.
5479 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5481 * Removed the rng context from SilcPacketContext structure and
5482 changed that the packet routine uses the Global RNG API.
5484 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5486 * Added support for quit message that client can "leave" on the
5487 channel when it quits the SILC. It is ditributed inside the
5488 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5490 Added silc_server_free_client_data that will take the
5491 signoff message as argument.
5493 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5495 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5497 * Updated parts of the protocol specification to keep it up
5500 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5502 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5503 payloads in one packet.
5505 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5506 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5507 use now the new List flag.
5509 * Also deprecated the following packet types: REPLACE_ID,
5510 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5512 * Added list support for Notify packet in server.
5514 * Added silc_server_send_notify_channel_change to send the
5515 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5516 the silc_server_send_replace_id.
5518 * Added silc_server_send_notify_nick_change to send the
5519 NICK_CHANGE notify type. Deprecates the function
5520 silc_server_send_replace_id.
5522 * Added silc_server_send_notify_join to send the JOIN notify type.
5523 Deprecates the function silc_server_send_new_channel_user.
5525 * Added silc_server_send_notify_leave to send LEAVE notify type.
5526 Deprecates the function silc_server_send_remove_channel_user.
5528 * Added silc_server_send_notify_cmode and
5529 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5530 types. Deprecates the silc_server_send_set_mode function.
5532 * Added SERVER_SIGNOFF notify type to indicate that server has
5533 quit. This means that all clients on the channel from that
5534 server will drop. This can be also used when netsplit happens.
5536 Deprecated REMOVE_ID packet type since it is not needed anymore
5539 Added silc_server_send_notify_server_signoff to send the
5540 SERVER_SIGNOFF notify type. Deprecates the function
5541 silc_server_send_remove_id.
5543 Added also silc_server_send_notify_signoff to send the
5544 SIGNOFF notify type.
5546 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5547 SILC protocol from this day on. Changed the protocol
5548 specification as well.
5550 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5551 notify type. It is used between routers to notify about
5552 topic changes on a channel.
5554 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5557 * Partly updated the protocol specification to comply with the
5558 changes now made. It is still though a bit outdated.
5560 * The JOIN notify type now takes one extra argument <Channel ID>.
5561 The packet used to be destined to the channel but now the
5562 JOIN type may be sent as list thus it is impossible to
5563 destine it to any specific channel. By adding this argument
5564 it is again possible.
5566 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5568 * Added CREDITS file. The CHANGES and CREDITS file will appear
5569 in the distribution as well.
5571 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5573 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5574 types in the server's silcd/packet_receive.c.
5576 * Implemented CMODE and CUMODE to work in router environment.
5578 * Fixed minor encoding and decoding buglet from the
5579 lib/silccore/silcmode.c.
5581 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5584 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5586 * Changed all SilcConfigServer* and silc_config_server* to
5587 SilcServerConfig* and silc_server_config*, respectively.
5590 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5592 * Associated the ID (client or server ID) to the Authentication
5593 Payload to avoid any possibility of forging. Updated the
5594 protocol specification and the code accordingly.
5596 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * The RSA key length is now save to the RsaKey context in the
5599 key generation process in lib/silccrypt/rsa.c. The key length
5600 is now used to figure out the maximum size of the block allowed
5601 to be encrypted/signed.
5603 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5604 is equivalent to the silc_mp_mp2bin but does not allocate any
5607 * Changed silc_mp_mp2bin API to take length argument. If it is
5608 non-zero then the buffer is allocated that large. If zero, then
5609 the size is approximated using silc_mp_sizeinbase, which however
5612 * Created Global RNG API which is global RNG that application can
5613 initialize. After initializing, any routine anywhere in the
5614 code (including library) can use RNG without allocating a new
5615 RNG object. This was done to allow this sort of use of the
5616 RNG in code that has no chance to allocate RNG object. All
5617 applications currently allocate this and many routines in the
5618 library use this. Affected file lib/silccrypt/silcrng.[ch].
5620 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5621 it to use the Global RNG API.
5623 * Defined Authentication Payload into protocol specification that
5624 is used during SILC session to authenticate entities. It is
5625 used for example by client to authenticate itself to the server
5626 to obtain server operator privileges.
5628 Implemented this payload into the lib/silccore/silcauth.[ch].
5629 Implemented also routines for public key based authentication
5630 as the new protocol specification dictates.
5632 Moved definitions of different authentication methods from
5633 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5635 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5636 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5637 silc_pkcs_verify_with_hash functions into the file
5638 lib/silccrypt/silcpkcs.[ch].
5640 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5642 * The client entry's userinfo pointer must be always valid.
5643 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5644 will fail since it requires the userinfo. Now, the userinfo
5645 is allocated as "" if actual userinfo does not exist. Actually,
5646 it must exist and it is totally Ok to drop client connections
5647 that does not announce the userinfo. However, we will make
5648 this workaround for now.
5650 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5651 to return the remote port by socket.
5653 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5655 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5656 SILC_SERVER_PENDING_EXEC and added an new macro
5657 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5658 data or when error occurs while processing the pending command.
5660 Added new argument `destructor' into silc_server_command_pending
5661 and to the SilcServerCommandPending object. This destructor is
5662 now called after calling the pending callback or if error occurs
5663 immediately. If error occurs the actual pending callback won't
5664 be called at all - only the destructor. The destructor may be
5665 NULL if destructor is not needed.
5667 All this applies for client library code as well. Similar
5668 changes were made there as well for the pending commands.
5670 In the client, the application must now allocate the
5671 SilcClientCommandContext with the silc_client_command_alloc
5674 * Added reference counter to the SilcServerCommandContext. Added
5675 function silc_server_command_alloc and silc_server_command_dup
5678 Same type of functions added to the client library for the same
5681 * Removed the cmd_ident from IDListData away since it is now
5682 global for all connections. It is the command identifier used
5683 in command sending and with pending commands. The affected file
5686 * Added reference counter to the SilcSocketConnection objecet to
5687 indicate the usage count of the object. The object won't be
5688 freed untill the reference counter hits zero. Currently only
5689 server uses this, and client ignores it. The client must be
5690 set to use this too later. The affected files are
5691 lib/silccore/silcsockconn.[ch]. Added also the function
5692 silc_socket_dup to increase the reference counter.
5694 This was mainly added because it is possible that the socket
5695 is removed underneath of pending command or other async
5696 operation. Now it won't be free'd and proper DISCONNECTING
5697 flags, etc. can be set to avoid sending data to connection that
5698 is not valid anymore.
5700 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5701 the connection. After that it sets SILC_SET_DISCONNECTED.
5702 It is, however, possible that the socket data is not still freed.
5703 The silc_server_packet_process now checks that data is not
5704 read or written to connection that is DISCONNECTED. The socket
5705 get's freed when the reference counter hits zero.
5707 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5709 * Changed the client operation API: channel_message operation's
5710 `sender' is now the client entry of the sender, not the nickname
5711 and the `channel' is the channel entry, not the channel name.
5713 In the private_message operation the `sender' is now also the
5714 client entry of the sender not the nickname.
5716 Affected file is lib/silcclient/ops.h and all applications
5717 using the client operations.
5719 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5721 * Moved the calling of ops->connect() from connect_to_server_final
5722 into receive_new_id functin since that is the point when the
5723 client is actually allowed to send traffic to network. The
5724 affected file is lib/silcclient/client.c.
5726 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5728 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5729 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5730 (if needs broadcasting) instead of broadcasting the packets one
5731 by one which would make a burst in the network traffic.
5733 * Added `broadcast' argument to the functions in silcd/server.[ch]
5734 silc_server_create_new_channel[_with_id] to indicate whether
5735 to send New Channel packet to primary router.
5737 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5739 * Added new function into the silcd/server.[ch] files:
5740 silc_server_create_new_channel_with_id to create new channel with
5741 already existing Channel ID.
5743 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5744 lib/silccore/silcpacket.h. This packet is used t send list of
5745 Set Mode payloads inside one packet. Server uses this to set
5746 the modes for the channels and clients on those channels, that it
5747 announced to the router when it connected to it. The protocol
5748 specification has been updated accordingly.
5750 * The silc_server_new_channel did not handle the packet coming
5751 from normal server as it normally does not send that. However,
5752 when it announces its channels it does send it. Implemented
5753 the support for that.
5755 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5756 into the file lib/silccore/id.h.
5758 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5760 * Fixed memory leaks in the functions silc_idlist_del_client,
5761 silc_idlist_del_channel and silc_idlist_del_server in the file
5762 silcd/idlist.c. All of those leaked like a sieve.
5764 * Fixed some small memory leaks in the client's function
5765 silc_client_notify_by_server.
5767 * Added functions into silcd/server.c: silc_server_announce_clients,
5768 silc_server_announce_channels and silc_server_announce_server.
5769 These functions are used by normal and router server to announce
5770 to its primary router about clients, channels and servers (when
5771 router) that we own. This is done after we've connected to the
5774 These functions effectively implements the following packet types:
5775 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5776 and SILC_PACKET_NEW_ID_LIST.
5778 * Added new functions into the silcd/packet_receive.[ch]:
5779 silc_server_new_id_list, silc_server_new_channel_list and
5780 silc_server_new_channel_user_list to handle the incoming
5781 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5783 * Added support of changing Channel ID in the function
5784 silc_server_replace_id. If the server that announces a channel
5785 to the router already exists in the router (with same name but
5786 with different Channel ID), router is responsible to send
5787 Replace ID packet to the server and force the server to change
5788 the Channel ID to the one router has.
5790 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5791 client that the Channel ID has been changed by the router. The
5792 normal server sends this to the client. Client must start using
5793 the new Channel ID as the channel's ID.
5795 Implemented handling of this new type into lib/silcclient/client.c
5796 into the function silc_client_notify_by_server.
5798 * Added new function silc_idlist_replace_channel_id into the files
5799 silcd/idlist.[ch] to replace the Channel ID.
5801 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5803 * Call silc_server_command_identify_check always when processing
5804 the IDENTIFY command in silcd/command.c
5806 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5809 send keepalive packets. The packet can be sent by clients,
5810 servers and routers.
5812 Added function silc_socket_set_heartbeat into the file
5813 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5814 If not set, the heartbeat is not performed. The actual
5815 heartbeat is implemented in the low level socket connection
5816 library. However, application is responsible of actually
5819 Added silc_server_send_heartbeat to send the actual heartbeat
5820 packet into silcd/packet_send.[ch]. Server now performs
5821 keepalive with all connections.
5823 * Added silc_task_get_first function into lib/silcutil/silctask.c
5824 to return the timeout task with shortest timeout. There was a bug
5825 in task unregistration that caused problems. TODO has been
5826 updated to include that task system must be rewritten.
5828 * The client library will now resolve the client information when
5829 receiving JOIN notify from server for client that we know but
5830 have incomplete information.
5832 * Rewrote parts of silc_server_remove_from_channels and
5833 silc_server_remove_from_one_channel as they did not remove the
5834 channel in some circumstances even though they should've.
5836 * Encryption problem encountered in server:
5838 The LEAVE command used to send the Channel Key packet to the
5839 router immediately after generating it. However, the code
5840 had earlier sent Remove Channel user packet but not immediately,
5841 ie. it was put to queue. The order of packets in the router
5842 was that Channel Key packet was first and Remove Channel User
5843 packet was second, even though they were encrypted in the
5844 reverse order. For this reason, MAC check failed. Now, this
5845 is fixed by not sending the Channel Key packet immediately but
5846 putting it to queue. However, this is more fundamental problem:
5847 packets that are in queue should actually not be encrypted
5848 because packets that are sent immediately gets encrypted
5849 actually with wrong IV (and thus MAC check fails). So, packets
5850 that are in queue should be encrypted when they are sent to
5851 the wire and not when they put to the queue.
5853 However, the problem is that the current system has not been
5854 designed to work that way. Instead, the packet is encrypted
5855 as soon as possible and left to the queue. The queue is then
5856 just purged into wire. There won't be any fixes for this
5857 any time soon. So, the current semantic for packet sending
5860 o If you send packet to remote host and do not force the send
5861 (the packet will be in queue) then all subsequent packets to the
5862 same remote host must also be put to the queue. Only after the
5863 queue has been purged is it safe again to force the packet
5866 o If you send all packets immediately then it safe to send
5867 any of subsequent packets through the queue, however, after
5868 the first packet is put to queue then any subsequent packets
5869 must also be put to the queue.
5871 Follow these rules and everything works fine.
5873 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5875 * Added new function silc_server_remove_clients_by_server to
5876 remove all client entries from ID list when the server connection
5877 is lost. In this case it is also important to invalidate all
5878 client entires as they hold the invalid server entry. This
5879 fixes fatal bug when server has lost connection and will reconnect
5882 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5884 * Made some sanity checks to silc_server_daemonise like to check
5885 whether the requested user and group actually exists.
5887 * Added sanity check to SKE's silc_ske_responder_finish to check
5888 that the public and private key actually is valid.
5890 * Invalidate the client's nickname when receiving Replace ID
5891 packet and the Client ID is being replaced. This means that the
5892 server will query the nickname if someone needs it (client)
5895 * Sort the ID Cache in client library when the ID Cache data
5896 has changed (needs sorting).
5898 * Do not allow for SILC client to create several connections to
5899 several servers. The client does not support windows right now
5900 and generating multiple connections causes weird behaviour.
5902 Irssi-silc client does support windows and can handle several
5903 connections without problems, see: www.irssi.org and SILC plugin.
5905 * Fixed some places where client was added to the IDList. The
5906 rule of thumb is following (in order to get everything right):
5907 If the client is directly connected local client then the
5908 `connection' argument must be set and `router' argument must be
5909 NULL to silc_idlist_add_client function. If the client is not
5910 directly connected client then the `router' argument must
5911 bet set and the `connection' argument must be NULL to the
5912 silc_idlist_add_client function.
5914 * The funtion silc_server_packet_send_local_channel actually did
5915 not check whether the client was locally connected or not. It
5916 does that now. Fixed a bug related to LEAVE command.
5918 * Fixed Remove Channel User payload parsing bug in server's
5919 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5921 * The server's silc_server_save_channel_key now checks also the
5922 global ID list for the channel as it might not be in the local
5923 list. Fixed a bug related to LEAVE command.
5925 * Is this the end of the [<unknown>] buglet that has been lurking
5926 around for a long time? A little for loop fix in server's
5927 silc_server_command_whois_parse that is used by both IDENTIFY
5928 and WHOIS command. At least, this was a clear bug and a cause
5929 of one type of [<unknown>] buglet.
5931 * WHOIS and IDENTIFY commands call the function
5932 silc_server_command_[whois/identify]_check function even if
5933 we are not router server.
5935 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5937 * Added --with-gmp configuration option. If set the GMP
5938 is always compiled in the SILC source tree. If not set then
5939 it is checked whether the system has the GMP3 installed. If
5940 it has then the GMP won't be compiled (the system's headers
5941 and library is used), if it doesn't have it then the GMP is
5942 compiled in the SILC source tree.
5944 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5946 * Changed RSA private exponent generation to what PKCS #1
5947 suggests. We try to find the smallest possible d by doing
5948 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5949 not security fix but optimization.
5951 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5953 * Added new config entry [Identity] to fork the server and run
5954 it as specific user and group. A patch from Bostik.
5956 * Imported Dotconf configuration library into lib/dotconf.
5957 This will be used to create the SILC configuration files later.
5958 It will appear in the distsribution after this commit.
5960 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5962 * A big code auditing weekend happening. Auditing code for
5963 obvious mistakes, bugs and errors. Also, removing any code
5966 Removed files for being obsolete:
5968 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5969 inline in the file lib/silcutil/silcbuffer.h)
5971 o lib/silcutil/silcbufutil.c (the header has inline versions)
5973 Changed code to fix possible error conditions:
5975 o The buffer formatting routines now check that the destination
5976 buffer really has enough space to add the data. This applies for
5977 both buffer formatting and unformatting
5978 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5979 unformatting was changed to accomodate following rules:
5980 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5981 sent to the function while XXX_*STRING will not allocate or copy
5982 the data into the buffer. Instead it sets the pointer from the
5983 buffer into the pointer sent as argument (XXX_*STRING used to
5984 require that the pointer must be allocated already). This change
5985 makes this whole thing a bit more consistent and more optimized
5986 (note that the data returned in the unformatting with XXX_*STRING
5987 must not be freed now). The routines return now -1 on error.
5989 o Tried to find all code that use buffer_format and buffer_unformat
5990 and added return value checking to prevent formatting and
5991 especially unformatting errors and possible subsequent fatal
5994 o Changed ske->x and ske->KEY to mallocated pointers in
5995 lib/silcske/silcske.h. Fixed possible data and memory leak.
5997 o Added return value checking to all *_parse* functions. Fixed
5998 many memory leaks as well.
6000 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6001 so that buffer overflows would not happen. All code now also
6002 checks the return value as it can fail.
6004 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6006 * Added reconnection support to server if the normal server looses
6007 its connection to the router (for example if router is rebooted).
6008 The server performs normal reconnection strategy implemented
6009 to the server. Affected file silcd/server.c.
6011 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6013 * Added new packet type SILC_PACKET_SET_MODE that is used to
6014 distribute the information about changed modes (for clients,
6015 channels and clients channel modes) to all routers in the
6016 network. Updated the protocol specification accordingly.
6018 Added functions into silcd/packet_send.c and
6019 silcd/packet_receive.c: silc_server_send_set_mode,
6020 silc_server_set_mode.
6022 Added new files silcmode.[ch] into lib/silccore that implements
6023 the encoding and decoding of Set Mode Payload. Added new type
6024 SilcSetModePayload. Moved the definitions of different modes
6025 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6027 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6029 * Oops, a little mistake in server's connection authentication
6030 protocol. The protocol is not ended with FAILURE but with
6031 SUCCESS if the authentication is Ok. :) Affected file is
6034 * Implemented NICK_CHANGE notify handling in server in the file
6035 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6036 the local clients on the channel. After the changing nickname
6037 in router environment snhould work and the [<unknown>] nickname
6038 should appear no more.
6040 The silc_server_replace_id function that receives the Replace ID
6041 payload now sends the NICK_CHANGE notify type also in the file
6042 silcd/packet_receive.c
6044 * Changed WHOIS and IDENTIFY command to support the maximum amount
6045 of arguments defined in protocol specs (3328 arguments). This
6046 fixed a bug that caused problems when there were more than three
6049 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6051 * Added extra parameter, command identifier, to the
6052 silc_client_send_command so that explicit command identifier
6055 Changed that ID list routines uses specific command identifier
6056 when sending WHOIS/IDENTIFY requests to the server so that they
6057 can be identified when the reply comes back.
6059 Affected files lib/silcclient/command.[ch],
6060 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6062 * Added `sender' argument to silc_server_packet_send_to_channel
6063 to indicaet the sender who originally sent the packet to us
6064 that we are now re-sending. Ignored if NULL. Affected file
6065 silcd/packet_send.[ch].
6067 * Added some server statistics support in silcd/server_internal.h
6068 SilcServerStatistics structure and around the server code. Also
6069 send some nice statistics information when client is connecting
6072 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6074 * Fixed channel ID decoding in server's JOIN command reply in
6075 silcd/command_reply.c
6077 * Fixed braodcasting of replace ID payload to not to send it if
6078 we are standalone server in silcd/packet_receive.c.
6080 * Fixed all channel message sending routines to not to send
6081 packets to clients that has router set, since they are routed
6082 separately in the same function earlier. Affects file
6083 silcd/packet_send.c and all channel packet sending functions.
6085 * In USERS reply, res_argv[i] are not allocated, the table
6086 is allocated. Thus changed that free the table, not its
6089 * In server's whois_check and identify_check if the client is
6090 locally connected do not send any WHOIS commands - they are not
6093 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6095 * Fixed some minor bugs in client when sending WHOIS command. The
6096 arguments was in wrong order.
6098 * Removed statis function add_to_channel from server in
6099 silcd/command.c that was previously used with the joining but
6102 * Tested USERS command in router environment successfully with two
6103 routers, two servers and two clients.
6105 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Reorganized the USERS command and command reply in client library
6108 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6109 When the command is given by user we register a pending command
6110 callback that will reprocess the command after the reply has been
6111 received from the server. When reprocessing the packet we then
6112 display the information. Thus, the USERS information is displayed
6113 now in the command callback instead of in the command reply
6114 callback. The processing of the command is same as previously
6115 when server has sent the command reply in the JOINing process.
6117 * Added to USERS command in silcd/command_reply.c to join the client,
6118 we didn't use to know about, to the channel after we've created
6119 a client entry for it. Also, for clienet we did know already still
6120 check whether it is on the channel or not and add it if not.
6122 * Removed silc_server_command_join_notify as the function and its
6125 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6127 * Changed the client's pending command handling to the same as the
6128 server's pending command handling. It is also now possible to
6129 execute command reply functions from other command reply
6130 function as the function callbacks for commands and command
6131 replies are one and same. The pending commands are not static
6132 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6133 in client connection context. Thus, pending commands are server
6134 connection specific as it is convenient.
6136 Changed the function silc_client_command_pending and
6137 silc_client_command_pending_del and added new function
6138 silc_client_command_pending_check. Removed the
6139 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6142 * Added cmd_ident, current command identifier, to the client
6143 connection context in lib/silcclient/client.h to keep track on
6144 command identifiers used in command sending. Client's command reply
6145 function handling now supports the mandatory command identifiers.
6147 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6148 funtions in client to fully support pending command callbacks.
6150 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6151 as one of the arguments to the application in the command reply
6154 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6155 before first releasing SILC but came back. Now it is removed again
6156 and should come back nomore. The FORWARDED flag was used only
6157 by the JOINing procedure by forwarding the command packet to router.
6158 Now, the JOINing procedure has been changed to more generic (due
6159 to various router environment issues) and FORWARDED is not needed
6160 anymore for anything. The protocol specification is yet to be
6163 Now, removed silc_server_packet_forward from server and the flag
6164 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6166 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6168 * Renamed NAMES command to USERS command. The NAMES was named that
6169 due to historical reasons. Now it is renamed. Also, rewrote
6170 parts of the USERS command. The nickname list is not sent anymore
6171 by the server. Only Client ID and mode lists are sent in the USERS
6172 command. Changed this also to the protocol specification.
6174 The client now resolves the names and stuff after it receives
6175 the USERS list from the server when joining to the channel.
6177 * WHOIS and IDENTIFY commands has been changed to support multiple
6178 Client ID's per command. One can now search for multiple users
6179 in the network by sending only one WHOIS or IDENTIFY command.
6180 Changed the code and the protocol specifications.
6182 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6183 uses silc_server_command_whois_parse to parse the request. */
6185 * If normal server, do not parse the WHOIS and IDENTIFY requests
6186 before sending it to the router. Saves some time.
6188 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6190 * Fixed JOIN command on client library. Wrong number of arguments
6191 used to crash the client.
6193 * Added silc_server_channel_has_global function to check whether
6194 channel has global users or not.
6196 * Added silc_server_channel_has_local function to check whether channel
6197 has locally connected clients on the channel.
6199 * The silc_server_remove_from_one_channel now checks whether the
6200 channel has global users or not after given client was removed from
6201 the channel. It also checks whether the channel has local clients
6202 on the channel anymore. If it does not have then the channel entry
6203 is removed as it is not needed anymore.
6205 * The silc_server_notify now checks on JOIN notify whether the joining
6206 client is one of locally connected or global. If it is global then
6207 the channel has now global users on the channel and that is marked
6208 to the channel entry. Also, it now saves the global client to
6209 global list who is joining and JOINs it to the channel. This is
6210 for normal server, that is.
6212 Changed silc_server_send_notify_on_channel,
6213 silc_server_packet_relay_to_channel and
6214 silc_server_packet_send_to_channel check if we are normal server
6215 and client has router set (ie. global client) do not send the
6216 message to that client, as it is already routed to our router.
6218 * Implemented LEAVE notify type handling in silc_server_notify
6221 * Tested LEAVE command in router environment successfully. Tested
6222 with two routers, two servers and two clients.
6226 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6228 * Implemented SIGNOFF notify type handling in silc_server_notify
6231 * silc_server_remove_id now removes the client entry from all channels
6232 it has joined and thusly sends SIGNOFF notify type.
6234 * Rewrote the NAMES list generation in server by removing two excess
6235 loops. The lists are created now inside one loop.
6237 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6239 * silc_server_remove_channel_user checks now also global list
6240 for channel and client.
6242 * silc_server_new_channel_user checks now both local and global
6243 list for channel and client. Fixed a bug in client id decoding.
6244 Used to decode wrong buffer.
6246 * silc_server_channel_message checks now both local and global
6247 list for channel entry.
6249 * Tested channel joining (hence JOIN) in router environment
6250 successfully. Tested with two routers, two servers and two
6253 * Tested channel message sending in router environment successfully.
6255 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6257 * Added silc_server_save_channel_key into server.[ch] to save the
6258 received channel key in Channel Key payload processing. It is
6259 also used in JOIN command reply handling.
6261 Equivalent function silc_client_save_channel_key added into
6262 client.[ch] into client library.
6264 * Changed JOIN command reply to send information whether the channel
6265 was created or not (is existing already) and the channel key
6266 payload. Changed protocol specs accordingly.
6268 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6269 the request was sent by ID and not by nickname. Crashed on
6272 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6275 now correctly save the received data.
6277 * silc_server_free_sock_user_data now notifies routers in the
6278 network about entities leaving the network.
6280 At the same time implemented functions silc_server_remove_id
6281 and silc_server_send_remove_id to receive and send REMOVE_ID
6282 packets. The packet is used to notify routers in the network
6283 about leaving entities. The ID removed will become invalid in
6286 * Added function silc_idlist_del_server into server. Removes and
6287 free's server entry from ID list.
6289 * silc_server_private_message function now checks, if we are router,
6290 that the destination ID really is valid ID, naturally.
6292 * In router when NEW_ID packet is received (for new client) the
6293 hash of the Client ID is saved in the ID Cache but the
6294 client->nickname is set to NULL, instead of putting the hash
6297 IDENTIFY command now also checks that client->nickname must be
6298 valid. If it is not if will request the data from the server who
6299 owns the client. Added new function
6300 silc_server_command_identify_check.
6302 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6303 to set the command to already allocated Command Payload.
6305 * Tested private message sending in router environment with two
6306 routers, two servers and two clients. Fixed minor bugs and now
6309 * Fixed segfault from client's NAMES command. Used to crash if
6312 * Forwarded packets must not be routed even if it is not destined
6313 to the receiver. Changed server code comply with this.
6315 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6317 * Added `require_reverse_mapping' boolean value to ServerParams
6318 structure. If TRUE (not default) the server will require that
6319 the connecting host has fully qualified domain name.
6321 If the reverse mapping is not required and hostname could not be
6322 found the IP address is used as hostname.
6324 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6326 * Implemented version string checking to both client and server.
6327 The check is incomplete currently due to the abnormal version
6328 strings used in development version of SILC.
6330 * Changed all command functions in server to use the new
6333 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6335 * Changed char *data to unsigned char *data in ID Cache system to
6336 support binary data as ID Cache data. Changed code to support
6337 binary data in lib/silccore/idcache.c.
6339 * Renamed silc_server_packet_relay_command_reply to
6340 silc_server_command_reply as it is normal packet receiving
6341 function. Rewrote the function to accept command replys for
6342 servers and not only for clients.
6344 * Mark remote router always as registered server if we are connecting
6345 to it. Otherwise, commands sent by the router to us are ignored.
6347 * All ID List find routines now returns the ID Cache Entry pointer
6348 as well if requested.
6350 * WHOIS command works now in router environment, tested with two
6351 routers, two servers and two clients.
6353 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6354 in router environment (as it is almost equivalent to WHOIS) but
6355 hasn't been tested thoroughly. Added new functions:
6357 silc_server_command_identify_parse
6358 silc_server_command_identify_send_reply
6359 silc_server_command_identify_from_client
6360 silc_server_command_identify_from_server
6362 * Disabled route cache adding because adding two different ID's with
6363 same IP replaces the old cache entry thus giving wrong route.
6364 The entry->router->connection is always the fastest route anyway
6365 so route cache may not be needed. Of course, new routes maybe
6366 established after receiving the ID when the entry->router->connection
6367 might not be anymore the most optimal.
6369 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6371 * Add route cache for received ID for fast routing.
6373 * Added silc_server_packet_route to route received packet on router
6374 that is not destined to us.
6376 * Renamed silc_server_get_route to silc_server_route_get.
6378 * Added id_string and id_string_len fields into SilcServer to
6379 include encoded ServerID for fast comparing without excess
6380 encoding of the ID's.
6382 * Cleaned up WHOIS command on server side. Added following static
6385 silc_server_command_whois_parse
6386 silc_server_command_whois_check
6387 silc_server_command_whois_send_reply
6388 silc_server_command_whois_from_client
6389 silc_server_command_whois_from_server
6391 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6392 arguments in command replies. All command functions should be
6393 updated to use this macro.
6395 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6397 * Minor typo fixes on command reply handling on server.
6399 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6401 * Added silc_server_command_add_to_channel internal routine to add
6402 the client to the channel after router has created the channel and
6403 sent command reply to the server.
6405 * Added generic silc_server_send_command to send any command from
6408 * Use static buffer with ID rendering instead of duplicating data.
6410 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6412 * Fixed a channel user mode bug when joining to a channel server gave
6413 everybody channel founder rights, oops.
6415 * We mark ourselves as the router of the incoming server connection
6416 if we are router ourselves. This way we can check in some packet
6417 sending functions whether it is locally connected server. For
6418 incoming router connections we put NULL.
6420 * For router sending packets locally means now always sending the
6421 packet cell wide; to local clients and local servers. For normal
6422 server sending packet locally means sending it to only local
6425 * Fixed the JOIN command to really work in router environment. If the
6426 channel is created it is always created by the router. Router is
6427 also responsible of making the initial joining to the channel,
6428 sending JOIN notify to the sending server and distributing
6429 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6430 does not exist server doesn't do anything else but forward the
6431 command to the router which performs everything.
6433 * Added silc_server_send_channel_key function to send the Channel Key
6436 * Added silc_server_create_channel_key to create new channel key. The
6437 channel key is now re-generated everytime someone joins or leaves
6438 a channel, as protocol dictates. Note: channel->key_len is the
6441 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6443 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6444 packet_receive.[ch] to separate packet sending and receiving
6445 routines. The server.[ch] now includes everything else including
6446 actual packet processing (writing and reading data) and other
6449 Renamed silc_server_private_message_send_internal to
6450 silc_server_send_private_message. The routine is still though
6451 used only to relay private messages as server does not send
6452 private messages itself.
6454 Renamed silc_server_new_channel to silc_server_create_new_channel
6455 and added new function sicl_server_new_channel that handles the
6456 incoming New Channel packet. Added also new sending function
6457 silc_server_send_new_channel to send New Channel Payload.
6459 * Added new function silc_server_notify to process incoming notify
6460 packet to the server/router. Server may then relay the notify
6461 to clients if needed.
6463 * Added new function silc_server_new_channel_user to process incoming
6464 New Channel User packet. Router will redistribute the packet and
6465 send JOIN notify to its local clients and locally connected servers
6466 if needed. Normal server will send JOIN notify to its local client
6467 on same channel when received this packet. Added also corresponding
6468 sending function silc_server_send_new_channel_user to sent the
6471 * Added boolean route argument to send_notif_to_channel and
6472 packet_send_to_channel functions to attempt to route the packet
6473 if it is TRUE and send only locally if it is FALSE.
6475 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6477 * silc_server_replace_id now broadcasts the received replace ID
6478 packet if it is not broadcast packet already. The router must
6479 broadcast to inform other routers about changed ID.
6481 * Added backpointer to server's router into SilcServer context in
6482 silcd/server_internal.h.
6484 * Fixed silc_server_packet_broadcast to send correct broadcast
6487 * The channel key is now distributed to the local client as soon
6488 as it is received from the router (in router environment) so that
6489 no other packet may be sent for the channel until client has
6492 * silc_server_remove_channel_user now broadcasts the received
6493 Remove Channel User packet if it is not broadcast packet already.
6494 The router must broadcast to inform other routers about removed
6497 * Added users field into SilcPacketContext that is a reference count
6498 of the context. One can increase the reference count by calling
6499 silc_packet_context_dup which is now changed to just increase the
6500 reference count instead of duplicating the data. The reference
6501 count is decresed by calling silc_packet_context_free that will
6502 free the data after the reference count hits zero.
6504 For now on the packet context and everything allocated into it
6505 (including the raw packet from network) must be freed by calling
6506 the new silc_packet_context_free function. Added also new function
6507 silc_packet_context_alloc that must be used now to allocate the
6508 context. This also means that if a routine is asynchronous from
6509 silc_[client/server]_packet_parse_type the packet context must
6510 be duplicated by calling silc_packet_context_dup. Otherwise it
6511 gets free'd after silc_[client/server]_packet_parse_type returns.
6512 Also, one must remember that if packet is duplicated then its
6513 reference count must be decresed by calling the free function as
6514 many times as it was duplicated.
6516 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6517 from both client and server.
6519 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6521 * Made joining to a channel working in router environment.
6523 * Cleaned up JOIN command on server side and create function
6524 silc_server_command_join_channel internal routine to make the
6527 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6529 * Changed silc_command_pending list to SilcDList. Also, added
6530 `ident' field to SilcServerCommandPending structure to identify
6531 the reply and to call correct callback.
6533 Added silc_server_command_pending_check function to replace the
6534 corresnponding macro. The silc_command_pending list is not
6537 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6538 to set identifier to previously allocated Command Payload. It
6539 is used to set identifier for command when resending Command
6542 * Added silc_command_payload_encode_payload to encode Command
6543 Payload buffer from SilcCommandPayload structure.
6545 * Added silc_argument_payload_encode_payload to encode Argument
6546 payload buffer from SilcArgumentPayload structure.
6548 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6550 * Changed WHOIS command to support router connection on server side.
6551 The whois request is always sent to router unless the server is
6552 standalone server. After server has received the reply from the
6553 router will it send the reply to the client.
6555 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6556 broadcast received broadcast packet. The function is used only
6557 by router. The broadcast packet is always sent to the router's
6560 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6561 render given ID to printable string, for log files for example.
6563 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6565 * Made basic router to router connections working. At least they
6566 can now connect to each other but nothing really works the way
6567 they are supposed - yet.
6569 * Added new initiator token to RouterConnection configuration
6570 file in silcd/serverconfig.[ch]. It is used to tell whether we
6571 are the initiator to the remote router or whether we'll expect
6572 the other end to connect.
6574 * Moved registering of listener task to silc_server_init, hence
6575 the server starts listenning as soon as it is run, even if it
6576 does not have connections to other routers. Let's see how well
6579 * Changed default connection retry timeouts for more suitable in
6582 * Removed cipher and such arguments from silc_idlist_add_client
6583 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6584 Added new function silc_idlist_add_data to add the keys and stuff
6587 * Added SilcIDListData structure and added it to SilcClientEntry
6588 and SilcServerEntry as their first field in the structure. This
6589 way we can explicitly cast the ID entries to the SilcIDListData
6590 structure and get common data for the entries. In past, we had
6591 to first check what type of connection it is and then cast it to
6592 correct ID entry type. Now, we can directly cast the opaque
6593 pointer to the SilcIDListData (no matter what ID entry it actually
6594 is) and get the data needed.
6596 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6598 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6599 in some circumstances even if threre were timeout tasks, though not
6600 IO tasks, but tasks anyway. Now fixed.
6602 * Defined SilcServerConnection structure to hold connection specific
6603 stuff about directly connected servers and routers. The definition
6604 is currently in silcd/server_internal.h. I thought about having
6605 a bit more important role fro this struct but for now it is used
6606 only when connecting to other server (or router actually).
6608 * Added connecting retry support in server when connecting to
6609 router(s). The retry feature implement exponential backoff
6610 algorithm. Also, added SilcServerParams structure to hold default
6611 parameters for server. For now, it include these retry settings
6612 and are hard coded. After server is moded to be as Silc Server
6613 Library this structure will be more important.
6615 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6617 * Changed client librarys channel->clients table to SilcList and
6618 changed code accordingly.
6620 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6622 * Changed client's channel table to SilcList and changed code
6623 accordingly. Also changed SilcChannelClientEntry to include back-
6624 pointer to the channel so that client entry can use that structure
6625 as list as well and we have fast cross-reference to the channel.
6626 This change dramatically decreased the complexity of channel
6627 handling with client entry and vice versa (removed one extra
6628 loop when searching for channel entry from many functions).
6630 * Changed server->sim from table to SilcDList and changed code
6633 * NAMES command can now be used from user interface. It will show
6634 the user list on the channel, neatly.
6636 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6637 Code now saves realname of the user if it becomes available.
6639 * Renamed configure.in to configure.in.pre and made ./prepare
6640 script to automatically add correct version string to
6641 configure.in which it creates from configure.in.pre.
6643 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6645 * NAMES command reply now shows users mode with the nickname when
6648 * Moved silc_client_ch[u]mode[_char] functions from
6649 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6650 place sucks, they are utility functions and should be in some
6653 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6655 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6658 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6662 * Added TRQ (efficient deque and list library) into lib/trq. This is
6663 a very good list library that is currently used in the SILC. Defined
6664 SilcList API over the library because I didn't like the API very
6665 much. See lib/trq/silclist.h for the API and examples of how to
6666 use the API. Fixed various places in the code to use the new
6667 SilcList API. The SilcList is meant for lists that has a structure
6668 already defined as a list. It is not suitable to add just some
6669 context to the list (in TRQ, the context is the list actually).
6671 So, I defined SilcDList that can be used for the purpose where
6672 predefined list structure does not exit. This can be used as
6673 such list. Now some context just can be added to the SilcDList.
6674 Currently this list is not used in the SILC just yet, though there
6675 are a lot places where this can replace dynamically allocated
6676 tables and I will fix these places, later, to use SilcDList.
6677 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6678 and use TRQ internally).
6680 Also fixed some annoying warning messages that the original TRQ
6681 code generated. Also minor changes to TRQ's Makefile.in.
6683 * Added support for querying by Client ID to both WHOIS and
6684 IDENTIFY commands into server, as required by the protocol.
6686 * Removed method function pointers from SilcBuffer structure. They
6687 weren't used to anything and just increased the context size for
6688 no good reason. This change also made silc_buffer_alloc and
6689 silc_buffer_free functions inline functions.
6691 * Disabled command flooding detection support until it's fixed so
6692 that it accepts commands in but does not execute them more than once
6695 * Added silc_net_localhost(), to return local hostname, into
6696 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6697 that must be initialized before calling silc_client_init.
6699 * Added new function: silc_server_send_notify_on_channels to send
6700 notify messages to all channels client has joined. It is assured
6701 that the message is sent only once per client.
6703 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6704 lib/silcutil/silcutil.[ch] as silc_format function. The new
6705 function is generic and is used by server as well, not only by
6706 the logging routines.
6708 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6709 the provided version string was not acceptable. Added new function:
6710 silc_ske_check_version into lib/silcske/silcske.h. The function
6711 must be implemented by the application (client or server) and it
6712 does not reside in the SKE library. The function checks the version
6713 string remote end sent.
6715 * Added back pointers (to opaque context and to SilcSocketConnection)
6716 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6718 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6719 duplicate packet context structure.
6721 * Changed `notify' client operation to send same arguments as client
6722 receives from server except for ID's. ID's are mapped to correct
6723 ID entry and that is returned. Also, if channel entry is not sent
6724 by server but the notify is for channel the channel entry is sent
6725 to application (otherwise application doesn't know that it is for
6726 channel (library gets it from packet's Destination ID)).
6728 * Added silc_client_remove_from_channels into client library to
6729 remove a client from all channels it has joined to. Used when
6730 received SIGNOFF notify from server. Added also new function
6731 silc_client_replace_from_channels to replace old ID entry with
6732 new ID entry on all channels. Used when received NICK_CHANGE
6735 * Fixed ID Cache list handling in silc_idlist_get_client in
6736 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6737 to get (or query) client by ID.
6739 * Updated TODO list.
6741 * Added connection authentication status message defined by the
6742 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6743 support for these into the code in client and server side.
6745 * Added generic function silc_client_send_command to send any command
6746 with variable argument list. Application should use this function
6747 to send commands if the command functions provided by the library
6748 does not suite for the application's user interface needs.
6750 * Added new `failure' client operation. Application is notified about
6751 received failure packet if client is executing a protocol. In this
6752 case the protocol's execution has failed.
6754 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6755 is required by the protocol.
6757 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6758 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6761 * Added status flag to SilcSKE object to indicate realtime status
6762 of the SKE protocol.
6764 * Application receives now exactly same command reply arguments as
6765 the library receives from server. However, if ID is received the
6766 corresponding ID entry is returned to the application (eg. Client
6767 ID is mapped to correct SilcClientEntry entry and that is returned).
6768 Changed command_reply client operation due to this change.
6770 * Changed all ID's in commands and in command replys as ID Payloads.
6771 Change affected both client and server side codes.
6773 All ID's sent in SILC network (with execption of ID's in SILC
6774 Packet header) are sent in ID Payload to support variable length
6777 * Server now notifies nick changes and notifies all clients on
6778 the channels about the new nickname (about the new Client ID,
6781 * Implemented CMODE command to change channel modes. Supports all
6782 channel modes defined by the protocol specs except ban and invite
6783 lists. (Also, private channel key mode is supported but support for
6784 setting private channel key in client is missing, thus, this mode
6785 has no effect on client side (except that server requires that the
6786 client uses private channel key and normal channel traffic does not
6789 Also, invite mode works per se, but INVITE command does not work
6790 yet correctly, so you can set channel as invite only channel but
6791 inviting clients to the channel does not work (it is yet to be
6792 thought what's the best way to do it).
6794 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6795 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6796 Implemented CUMODE command to change user's mode on the channel.
6797 Supports all modes defined by the protocol specs.
6799 * Added NAMES command reply to return users modes on the channel.
6801 * Removed unnecessary and slow ciphers from lib/silccrypt.
6803 * Set SO_KEEPALIVE option to connection sockets by default.
6805 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6807 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6808 redefined the Notify Payload into protocol specs.
6810 * Added silc_id_payload_parse_id to get ID directly from raw
6813 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6815 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6816 accept searching by Client ID as well.
6818 * Added support for LEAVE and SIGNOFF notify types in client library.
6820 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6821 to parse ID Payload from raw data.
6823 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6825 * Added flags parameter into silc_ske_assemble_security_properties
6826 function in lib/silcske/silcske.[ch].
6828 * Changed notify client operation to fit better for notify messages
6829 sent by server. The notify payload received from server is now
6830 passed to the application (after parsing it to SilcNotifyPayload).
6831 It is application's responsibility to retrieve the arguments
6832 from the payload and show the message the way it wants. The message
6833 sent by server is implementation specific.
6835 * Changed public keys to comply with the protocol specification.
6836 Old public keys are not supported anymore and are not compatible.
6838 * Removed nickname from Channel Payload as the latest draft removed
6839 it. The client must resolve the nickname from the NAMES command
6840 reply received when it joined the channel.
6842 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6844 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6846 * Fixed some errors in protocol specification drafts.
6848 * Created lib/silccore/silcnotify.c to implement Notify Payload
6849 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6850 generic payloads described by protocol specifications. The file
6851 includes implementations for ID Payload and Argument Payload.
6853 * Changed Command Payload implementation to use the new Argument
6854 Payload. Changed command_xxxx_payload to command_payload_xxxx
6855 to comply with SILC coding conventions.
6857 * Added suppport for Argument Payload handling in Notify Payload
6858 implementation as protocol requires it. Added the new support
6859 into server and client lib as well.
6861 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6863 * Added support for multiple nicknames on same channel. [n] is
6864 added locally to the nickname if there are more than one same
6865 nicknames on the channel.
6867 * Server now sends all nicknames that matched WHOIS request.
6868 Client also shows the list received from server.
6870 * Added TOPIC command to client side. User can now set and show
6871 current topic on channel.
6873 * Added MOTD command to client and server. Also, server sends the
6874 motd when client connects to the server.
6876 * Changed version strings to comply ISO 8601.
6878 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6880 * Fixed protocol error handling in client library. It should now
6881 cope even if the SKE fails for some reason.
6883 * Made new protocol specification drafts for submitting to IETF.
6885 * Implemented TOPIC command to server in silcd/command.c.
6887 * Added two new notify types into lib/silccore/silcnotify.h:
6888 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6889 notify nickname change and topic setting/change on a channel.
6891 * API change of command_reply operation in client library. The
6892 application gets now the status type received from server as well.
6894 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6896 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6898 * Cras fixed and optimized the packet handling even further and
6899 it should work now. Minor change to the prototype of function
6900 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6902 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6904 * Added new function into lib/silcutil/silcschedule.[ch]:
6905 silc_schedule_with_fd to select() a specified fd. The function
6906 returns after timeout expires or data arrives or goes. The
6907 function is used by packet routines to wait that all data is
6908 received from network.
6910 * Fixed data reading from network in lib/silccore/silcpacket.c.
6911 The code now assures that all data is read from the fd and then
6912 continues packet processing. This was a bug fix since the code
6913 used to drop some data in some circumstances.
6915 * Added new function into lib/silcclient/client.[ch]:
6916 silc_client_start_key_exchange to start key exchange after
6917 connection has been established to server. The code internally
6918 now uses this funtion but its main purpose was to provide it
6919 for applications that perform their own connecting. After
6920 application has created a connection it merely calls this
6921 function to start the key exchange between client and server.
6922 The library takes care of everything else after that.
6924 Updated also lib/silcclient/README to explain the usage of
6927 * Do not send to application information that connection has
6928 been established. Application gets notified it by connect
6931 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6933 * Applied cras's patch to add silc_schedule_one function. The
6934 function runs scheduler once and returns.
6936 * Fixed the scheduler after cras messed it up. The timeout
6937 handling works now as it's supposed to work.
6939 * Added into lib/silccore/ silcnotify.h to include notify
6940 message types support. Changed silc_server_send_notify*
6941 functions, in server.[ch], to support those new notify types.
6942 Added the support for the notify types into client library,
6943 as well. Added new notify client operation into ops.h in
6946 * Changed silc_server_packet_send_to_channel to send normal
6947 packets instead of just channel message packets. The function
6948 is now used to send the notify packets to channels. It is not
6949 used to send channel message packets anymore, as server never
6952 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6953 va_arg()s as it seems to require it nowadays. I guess, if SILC
6954 is compiled with older va_arg() the new code should work anyway.
6956 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6958 * Splitted core library. Core library (lib/silccore) includes
6959 now only SILC protocol specific core (and common) components.
6960 Created new utility library (lib/silcutil) that includes more
6961 generic purpose stuff. The stuff for util library was taken
6962 from the old core library. This was minor and easy split.
6964 * Created SILC Client Library (lib/silcclient) that includes
6965 implementation of the SILC client without user interface. This
6966 was major move from silc/ directory. The code has been changed
6967 so that it is transparent towards the user interface. The
6968 silc/ directory includes now the same user interface as before
6969 and it uses the new client library. Read lib/silcclient/README.
6970 Basicly, the client library performs everything else related
6971 to SILC except user interface handling. Also, configuration
6972 files are considered to be part of user interface and library
6973 does not handle them.
6975 This change also changed a lot of structures, function naming etc.
6976 Most important change was that SilcClientWindow object was
6977 renamed to SilcClientConnection in the client library. Created
6978 also new file lib/silcclient/ops.h. Also added new files
6979 silc/local_command.[ch] and silc/client_ops.[ch].
6981 All these changes were made to make it easier for user interface
6982 designers to create what ever user interface for the SILC client
6985 It is also expected that the server will be moved to lib
6986 directory as well and SILC Server Library will be created;
6987 sometimes in the future.
6989 * Removed Local commands from lib/silccore/silccommand.h as
6990 they are application specific and new client library does not
6991 handle any of those anymore.
6993 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6994 old client implementation in silc/.
6996 * Added support for callback functions in SILC_LOG_* macros.
6997 Application can now set its own callbacks that will be called
6998 instead of using the default functions that will always print
6999 the debug messages to stderr (or stdout). Also, debugging can
7000 now be disabled by setting silc_debug to FALSE and re-enabled by
7001 setting it to TRUE. Note, that logging will still work even
7002 if debugging is disabled.
7004 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7005 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7006 silc_log_reset_debug_callbacks.
7008 * To enable debugging in silc client one must give now -d
7009 option on command line.
7011 * Changed silc_schedule_init to automatically allocate task queues
7012 if they are not allocated before calling it.
7014 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7016 * Added GMP 3.1 into math library.
7018 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7020 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7021 a channel in SILC network. The packet is used by servers and
7022 routers to notify other routers that user has left a channel.
7023 This little feature was missing until now. Added the feature
7024 to protocol specification as well.
7026 Added functions: silc_server_send_remove_channel_user and
7027 silc_server_remove_channel_user into server.[ch].
7029 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7030 lib/silccore/silcpacket.h. However, they are not implemented
7033 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7035 * Fixed joining to a channel and sending channel messages
7036 between server and router. The channel message sending should
7037 now work inside a cell.
7039 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7041 * Fixed the private message sending between server and router.
7042 The private message sending should now work inside a cell.
7044 * Added silc_server_replace_id into server.[ch] to replace
7045 existing ID in the SILC network.
7047 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7048 and silc_idlist_replace_server_id into idlist.[ch] in server.
7050 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7052 * Fixed the server to server connections. Server can again now
7053 connect to router. Router to router connections probably does
7056 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7058 * Added dynamic protocol registering support. Now protocols can
7059 registered and unregistered on the fly. Patch by cras.
7061 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7063 * Added lib/contrib directory to hold routines that some platforms
7064 don't have but are needed by SILC.
7066 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7067 into lin/contrib to provide getopt() and getopt_long() for
7068 those who don't have it.
7070 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7072 * Added AWAY command to client. When away message is set and
7073 client receives a private message packet the client automatically
7074 replies to the sender with the away message.
7076 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7077 bug seemed to be the cause of recent problems when compiling
7080 * Added version detection support to SKE protocol specification
7081 and added the new changes to the SKE implementation as well.
7082 There were other minor changes in the SKE protocol as well.
7084 Many changes in lib/silcske/silcske.[ch] and in
7085 lib/silcske/payload.[ch].
7087 * Added ^U functionality, clear input line. Patch from cras.
7089 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7091 * Mainly small bugfixes on core library. Fixed some debugging
7092 logging and buffer overflow in silclog.c.
7094 * Updated config.sub and config.guess on the distribution tree.
7096 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7098 * Added command lagging support in server. Client may execute
7099 commands now only once in two seconds.
7101 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7103 * Optimized packet reception. MAC computation and checking is now
7104 also more optimized. A lot previously duplicated code is now
7105 used as generic by both client and server.
7107 * Fixed key pair generation in clientutil.c
7109 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7111 * Added into lib/silccore/silcbufutil.[ch] new function;
7112 silc_buffer_realloc.
7114 * Moved generic packet sending/encryption functions to
7115 lib/silccore/silcpacket.[ch] from client and server. Some
7116 rewriting of the functions.
7118 * Moved all generic packet reception/decryption functions to
7119 lib/silccore/silcpacket.[ch] from client and server. The
7120 packet processing is now much cleaner in both client and server.
7121 These were major changes in both client and server.
7123 * Created many common functions in server to do packet sending.
7124 Previously code were duplicated a lot, this has been removed
7127 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7129 * Rewrote major parts of the ID cache system. Don't know
7130 whether it is better now or not but at least the API is more
7133 * Major rewrite on ID cache stuff on client because of the ID
7134 cache API changes. Added idlist.c to client.
7136 * Also major rewrite on ID cache stuff on server as well.
7137 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7138 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7139 in hand, instead they are all put into the ID cache system now.
7140 All server_idlist_* routines uses ID cache now instead of
7141 traversing its own lists (those lists does not exist anymore).
7142 SilcIDList though still exists. Also, SilcXXXEntry's are
7145 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7147 * Finally made the SKE implementation compliant to the protocol
7148 specification. All mp integers are now binary encoded as
7149 opposed being HEX encoded.
7151 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7154 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7155 functions: silc_[encode/decode]_pem. Also added function
7156 silc_encode_pem_file to PEM encode with newlines ('\n') for
7159 * SILC public keys are now encoded either PEM or binary. Same
7160 option is for private keys as well. By default private keys
7161 are binary encoded and public keys PEM encoded. Silly HEX
7162 encoding were removed.
7164 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7165 function to create fingerprints.
7167 * Fixed a bug in SHA1; does not change the original data anymore.
7169 * Partly implemented INFO command on client and server side.
7170 Fixed CLEAR command. Changes to SERVER command; show current
7171 server(s) when giving command without arguments. Added
7172 VERSION command to client.
7174 * Added check to server that unregistered connections cannot
7175 execute commands (unless it is specificly allowed).
7177 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7179 * Fixed screen refresh.
7181 * Fixed channel joining bug from client. On some circumstances
7182 client tried to join to a channel it had already joined.
7184 * Added public key verification process into client's protocol.c.
7185 The client now verifies the public key from user and saves
7186 it into ~./silc/serverkeys/ directory.
7188 Added into: clientutil.[ch]: silc_client_verify_server_key.
7190 * Changed SKE protocol's silc_ske_initiator_finish function
7191 to accept callback function that verifies the received public
7192 key. Removed old silc_ske_verify_public_key function.
7194 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7196 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7197 silc_pkcs_private_key[_data]_set.
7199 * Made the password and public authentication more cleaner in
7200 server's protocol.c.
7202 * Removed historic and obsolete protocol `channel_auth' from
7203 both client and server.
7205 * Removed wrong way of sending command status messages from
7206 server to client in server's command.c. The old way violated
7207 protocol specification.
7209 Changes to silccore/silccommand.[ch]: removed
7210 silc_command_encode_status_payload -> not needed anymore,
7211 changed silc_command_encode_payload_va to accept extra
7212 argument on variable argument list. The argument type must
7213 now be provided to the function. Also, added new function:
7214 silc_command_encode_reply_payload_va which is same as
7215 normal command_encode_payload_va except command status type
7216 is provided as extra argument.
7218 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7220 * Added ~./silc directory handling. The directory includes the
7221 public and private keys for the client.
7223 Added silc_client_check_silc_dir, silc_client_create_identifier
7224 and silc_client_load_keys.
7226 * Implemented SILC protocol compliant public key. Added public
7227 and private key saving to and loading from files.
7229 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7230 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7231 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7232 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7233 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7235 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7236 silc_pkcs_load_[public/private]_key.
7238 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7240 * Added silc_server_get_route (route.[ch]) to get connection
7241 data for the fastest route for given ID.
7243 * Implemented INVITE command on client and server. The command
7244 were re-defined in the SILC Protocol Specification and the
7245 implementation now complies with the specification.
7247 * Implemented PING command on client and server.
7249 * Implemented NAMES command on client and server. The server side
7250 supports currently only normal server not router server yet.
7251 Some changes to NAMES definition in SILC protocol specification.
7253 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7255 * Implemented LEAVE command on client and server.
7257 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7258 again. This change was made to the protocol as well. Server
7259 should not violate the protocol specification anymore.
7261 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7263 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7264 was tested. SOCKS4 was not but should work anyway.
