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

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

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

219 algorithm parts and created new file silcalgs.conf, that
220 is now included from the example_silcd.conf.in.
222 * Optimized the silc_server_connect_to_router_second to take
223 the connection configuration object from the SilcServerConnection
224 object instead of finding it during the connecting phase.
225 Added the configuration object to SilcServerConnection struct.

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

311 zero port also if the hostname is NULL because it could not
314 Call file transfer monitor callback now also if error occurs
315 during key agreement protocol.
317 Changed the silc_client_file_send interface to return the
318 SilcClientFileError instead of session id. The session ID
319 is returned into pointer provided as argument.

338 * Fixed the channel message payload decryption in the function
339 silc_channel_message_payload_decrypt to not modify the original
340 buffer before it is verified that the message decrypted
341 correctly. Otherwise, next time it is called with correct
342 channel key it won't encrypt since the payload is corrupted.
343 Affected file lib/silccore/silcchannel.c.

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

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

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

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

561 for it with GETKEY command. Affected file silcd/command.c.
563 * Removed the use_auto_addr variable from default config
564 file since it was in wrong section. Affected file is
567 * Fixed TOPIC_CHANGE notification to not route it when it
568 was sent using silc_server_send_notify_to_channel function.
569 Affected file silcd/command.c.
571 * Fixed silc_server_send_notify_kicked to send the kicker's
572 Client ID also, it was missing. Affected files are
573 silcd/command.c, silcd/packet_send.[ch].
575 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
577 * Do not save client history information in SERVER_SIGNOFF.
578 Fixes the bug in normal server that it does not detect
579 the client becoming valid after the server becomes back
580 online. Affected file silcd/server_util.c.
582 * Added `sock_error' field into the SilcSocketConnection
583 context. When error occurs during socket operation (read
584 or write) the error is saved. Added also new function
585 silc_socket_get_error to return human readable socket error
586 message. Affected files are lib/silcutil/silcsockconn.[ch],
587 lib/silcutil/unix/silcunixsockconn.c, and
588 lib/silcutil/win32/silcwin32sockconn.c.
590 * The server now prints the socket error message in the
591 signoff for client. Affected file silcd/server.c.
593 * Fixed the `created' channel information sending from router
594 to server in JOIN command. Checks now whether the channel
595 really was created or not and set it according that.
597 Fixed the JOIN command to use the client entry's current
598 ID during the joining procedure instead of the one it sent
599 in the command (it is checked though), since it can change
600 between the packet processing and command processing, and
601 would just case unnecessary pain in the client end. Affected
602 file silcd/command.c.
604 * Fixed a channel key payload sending to use correct channel
605 ID when the server was forced to change the channel's ID by
606 router. Router sent the key payload with the old Channel ID.
607 Affected file silcd/packet_receive.c.
609 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
611 * Call silc_server_save_channel_key only if the key payload
612 was provided in the JOIN command's command reply. Affected
613 file silcd/command_reply.c.
615 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
617 * Fixed silc_mp_sizeinbase to return the value correctly with
618 MPI. Affected file lib/silcmath/mp_mpi.c.
620 * Fixed the stop_server signal to correctly stop the scheduler
621 and gracefully stop the server when SIGTERM or SIGINT signals
622 are received. Affected file silcd/silcd.c.
624 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
626 * Simple handling of TERM and HUP signals. Also added some log
627 flushing call around. Affected file is
630 * Fixed small bugs in silclog.c. Now buffering output will take
631 effect after 10 seconds since startup: This will ensure that
632 no important startup messages are lost. Also output redirection
633 will preserve original format ([Date] [Type] message).
634 Affected file is lib/silcutil/silclog.c.
636 * Added two options to the config file, in the logging section:
637 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
638 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
640 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
642 * Do not print the warning about log files not being initialized
643 more than once to avoid excess logging. Affected file is
644 lib/silcutil/silclog.c.
646 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
647 the SIM copying in make install in Makefile.am.pre.
649 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
651 * Rewritten silclog APIs. Globally interesting changes follows:
652 silc_log_set_files() changed to silc_log_set_file().
653 silc_log_set_callbacks() changed to silc_log_set_callback().
654 ROBOdoc documented silclog header file.
655 SilcLogCb now returns bool to wether inihibit the default
656 handler or not (to keep the old behaviour return always TRUE).
657 The new APIs should also fix the problem of the
658 silcd_error.log file that was written in the current directory.
661 Log files streams will remain opened after silc_log_set_file()
662 call, means less CPU usage notably on high traffic servers.
663 File streams are now full buffered, and flushed to the disk
664 every 5 minutes, lesses HD activity and CPU usage.
665 Messages can be redirected, allowing admins to configure
666 one single logfile for all server messages.
667 the silc_log_quick global variable to activate fast-logging.
668 Affected files lib/silcutil/silclog.[ch]
670 * Changed some code to conform new silclog APIs. Affected
671 files are doc/example_silcd.conf.in, silcd/server.c
672 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
675 * Fixed a memory leak that could occur in some situations.
676 Affected file silcd/serverconfig.c.
678 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
680 * Added the silc_client_del_client to remove the client from
681 all channels as well. Affected file lib/silcclient/idlist.c.
683 * Fixed the client library to correctly remove the client
684 from all channels when the client entry is being destroyed.
685 Affected file lib/silcclient/client_notify.c, command.c.
687 * Added auto-nicking support to the client library. If the
688 applicatio now sets client->nickname it will be sent to the
689 server after connecting by the library. This way for example
690 SILCNICK (or IRCNICK) environment variables will have effect
691 and always change the nickname automatically to whatever
692 it is wanted. Affected file lib/silcclient/client.[ch].
694 * Renamed silc_server_command_bad_chars to the
695 silc_server_name_bad_chars and moved it to the
696 silcd/server_util.[ch]. Added also new function
697 silc_server_name_modify_bad to return nickname that
698 includes bad characters as new nickname without those
699 bad characters. This check and modify is now used in
700 silc_server_new_client when the username is initially set
701 as nickname, so it must be checked to be valid nickname.
702 Affected file silcd/packet_receive.c.
704 * The nickname length is now taken from the packet for real
705 and not trusted to strlen() since it clearly can return
706 wrong length for nickname including bad characters. This
707 also applies to channel names. Affected file silcd/command.c.
709 * Removed the lib/silcsilm/modules directory. Modules are now
710 compiled into the lib/silcsim. Fixed the copying of the
711 modules to follow symbolic links in Makefile.am.pre.
713 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
715 * Fixed silc_string_regexify list creation. Fixes bugs with
716 BAN and INVITE commands in server. The affected file is
717 lib/silcutil/unix/silcunixutil.c.
719 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
721 * Removed the command destructor entirely from the server's
722 command and command reply routines. It is not needed, and
723 its usage was buggy and caused crashes. Affected files are
724 silcd/command[_reply].[ch].
726 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
728 * Cancel protocol and NULL sock->protocol if timeout
729 occurred during protocol. Affected file silcd/server.c.
731 * Cancel protocol timeouts always before calling the final
732 callback, to assure that after final callback is called
733 no other state will be called for the protocol anymore.
734 Affected file silcd/protocol.c.
736 * Print error log if incoming connection configuration could
737 not be found. Affected file silcd/server.c.
739 * Fixed JOIN command to correctly save the founder mode
740 to the client on normal SILC server, when the channel
741 was created by the router. Affected file silcd/command.c.
743 * Fixed LIST command (hopefully) to send correct reply
744 packets. Affected file silcd/command.c.
746 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
748 * The silc_packet_receive_process now returns FALSE if the
749 read data was invalid packet, and TRUE if it was ok.
751 The server now checks that if unauthenticated connection
752 sends data and its processing fails the server will close
753 the connection since it could be a malicious flooder.
755 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
757 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
759 * Make sure the warning about error opening a log file is
760 printed only once and not everytime it fails (produces
761 too much useless log). Affected file lib/silcutil/silclog.c.
763 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
765 * Made the silc_server_daemonise() function more readable.
766 Affected file silcd/server.c.
768 * Pid file is now optional, the user may comment it out from
769 the config file. Removed define SILC_SERVER_PID_FILE, we
770 don't need a default any longer. Affected file
771 configure.in.pre, lib/Makefile.am.pre.
773 * Make some use of the pid file. The server now dies at startup
774 if it detects a valid pid file on his path. The server would
775 die anyway in this circumstance, because of the bind() failure.
776 Affected file silcd/silcd.c.
778 * No longer compiling lib/dotconf.
780 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
782 * Fixed JOIN command parsing not to crash. Affected file
783 lib/silcclient/command.c.
785 * Fied the NICK_CHANGE notify to add the new client entry
786 even it is resolved. This removes an <[unknown]> nick
787 thingy bug in the client. Affected file is
788 lib/silcclient/client_notify.c.
790 * Do not try to allocate 0 bytes (efence does not like it)
791 in lib/silccore/silccomand.c when encoding payload.
793 * Do not take IRCNICK as nickname in Irssi SILC client since
794 it is not possible to set nickname before hand connecting
795 the server (TODO has an entry about adding auto-nicking
798 * Changed the silc_server_command_pending to check whether
799 there already exists an pending entry with the specified
800 command, command identifier and pending callback. This is
801 to fix IDENTIFY and WHOIS related crashes that may register
802 multiple pending commands with same identifier. Affected
803 file silcd/command.c.
805 * Fixed the server to reconnect to the router even if it
806 was already reconnecting and EOF was received. This to
807 fix a possibility that the server wouldn't ever try to
808 auto-reconnect to the router. Affected file silcd/server.c.
810 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
812 * Fixed the server's password authentication to use the
813 length of the locally saved password, and not the one
814 sent in the packet. Affected file silcd/protocol.c.
816 * Fixed same password authentication problem in the
817 Authentication Payload handling routines in
818 lib/silccore/silcauth.c.
820 * Yet another password authentication problem fixed with
821 channel password handling in silcd/command.c.
823 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
825 * If first character of string in silc_parse_userfqdn is '@'
826 then do not parse it. Affected file is
827 lib/silcutil/silcutil.c.
829 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
831 * Fixed minor bug in IDENTIFY command reply sending, which
832 caused various weird problems during JOIN when it was
833 resolving names for users. Affected file silcd/command.c.
835 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
837 * Fixed the IDENTIFY command reply sending to chech better valid
838 clients. It was possible to send incomplete list of replies.
839 Affected file silcd/command.c.
841 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
843 * Added silc_client_command[s]_[un]register functions now to
844 dynamically register the commands in client library. Removed
845 the static table of commands. This allows the client library
846 to call commands without causing the application to know about
847 what commands library has called.
849 Removed the INFO command reply kludge to detect when the command
850 was called by library. Now library use its own command reply
851 function for INFO command.
853 Added function silc_client_command_call to call a command.
854 Application can use it to call command, not access the structure
857 Now all commands that are sent by the client library (not
858 explicitly sent by application) use own command reply functions.
860 Affected files around lib/silcclient/ and in
861 irssi/src/silc/core/.
863 * Fixed the WHOIS command reply sending to chech better valid
864 clients. It was possible to send incomplete list of replies.
866 Fixed the WHOIS and IDENTIFY to send the request to router
867 if normal server did not do it and did not find any results.
869 Affected file silcd/command.c.
871 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
873 * Moved the internal data from SilcClient context into its
874 own file, not accesible to application. Affected files
875 lib/silcclient/client.h and lib/silcclient/client_internal.h,
876 and other files in client library.
878 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
880 * Added doc/examples installation target in Makefile.am.pre.
883 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
885 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
886 commands the found client entry will be removed from the
887 cache, after notifying application about the error. Affected
888 file lib/silcclient/command_reply.c.
890 * Changed the /MSG to check for exact nickname user gave, and
891 not let `nick' match `nick@host' if it is only one found. Now,
892 user must type the exact nickname (like nick@host2) even if
893 there are no more than one same nicks found. This is to avoid
894 a possibility of sending nickname to wrong nickname since
895 `nick' could match `nick@host'. Affected file is
896 irssi/src/core/silc-servers.c.
898 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
900 * Do not print "you are now server operator" or similar when
901 giving /away command. Affected files are
902 irssi/src/silc/core/client_ops.c, silc-servers.h.
904 * Made the silc_server_command_pending_error_check to send
905 the same command reply payload it received back to the
906 original sender of the command. This way all arguments
907 that was received by the server will be received by the
908 client too. Affected file silcd/command.c.
910 * Added the silc_idcache_add to return the created cache entry
911 to a pointer. Affected file lib/silccore/silcidcache.[ch].
913 * Add global clients to expire if they are not on any channel.
914 This is because normal server will never know if they signoff
915 if they are not on any channel. The cache expiry will take
916 case of these entries. This is done by normal servers only.
917 The affected files are silcd/command_reply.c,
918 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
920 * If server receives invalid ID notification for WHOIS or
921 IDENTIFY and the ID exists in the lists, it is removed.
922 Affected file silcd/command_reply.c.
924 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
925 in client then client entry that it matches is searched and
926 the nickname is printed on the screen for user. Affected
927 file irssi/src/silc/core/client_ops.c.
929 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
931 * Use cache entry expire time in the LIST command reply to
932 purge old entries from the cache after the LIST command
933 reply has been received. This way we don't have non-existent
934 entries in the cache for too long. Affected file is
935 silcd/command_reply.c.
937 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
939 * If we are normal server, and we've not resolved client info
940 in WHOIS or IDENTIFY from router, and it is global client,
941 we'll check whether it is on some channel. If it is not
942 then we cannot be sure about its validity and will resolve it
943 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
944 file silcd/command.c.
946 * Search channel by name (if possible) rather than by ID
947 in IDENTIFY command's command reply. Affected file is
948 silcd/command_reply.c.
950 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
952 * Distribute to the channel passphrase in CMODE_CHANGE notify.
953 Updated specs and implemented it. Affected file silcd/command.c,
954 silcd/packet_send.c and silcd/packet_receive.c.
956 * Implemented the <founder auth> payload handling in the JOIN
957 command. If provided all conditions for channel joining
958 except requirement to provide correct passphrase can be
959 overrided by the channel founder. Updated the protocol specs.
960 Affected file silcd/command.c.
962 Added support for founder auth in JOIN command in client
963 library. Fixed the parsing of the JOIN command now to support
964 all options as they should be. The affected file is
965 lib/silcclient/command.c.
967 * Optimized the WHOIS and IDENTIFY commands to send the request
968 to router only if it includes nicknames or other names. If
969 they include only IDs then check the local cache first before
970 routing. Affected file is silcd/command.c.
972 * Added channels topic announcements. Affected file is
973 silcd/packet_receive.c and silcd/server.c.
975 * Fixed the silc_server_send_notify_topic_set to really destine
976 the packet to channel. Affected file silcd/packet_send.c.
978 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
979 library. Affected file lib/silcclient/client_notify.c.
981 * Added UMODE announcements. Affected file silcd/server.c.
983 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
985 * Memory leak fixes in:
987 lib/silcutil/silcsockconn.c
988 lib/silcske/silcske.c
991 lib/silccrypt/silcpkcs.c
992 lib/silccore/silccommand.c
993 lib/silccore/silcidcache.c
998 * ROBOdoc documented the lib/silcske/groups.h file and a
999 bit changed the interface for better.
1001 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1003 * Update the client entry context in the ID cache after
1004 nick change. Affected file lib/silcclient/command.c.
1005 Fixes the CUMODE command when regaining founder privileges,
1006 and a little WHOIS problem.
1008 * Fixed silc_net_gethostbyname to correctly call the
1009 inet_ntop. Affected file lib/silcutil/silcnet.c.
1011 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1013 * Added IPv6 support checking to the configure.in.pre, added
1014 also --enable-ipv6 option to override the check. Affected
1015 file configure.in.pre.
1017 * The silc_thread_create now calls the start function
1018 directly if threads support is not compiled in. Removes
1019 ugly #ifdef's from generic code. Affected files are
1020 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1022 * Added silc_net_gethostby[name/addr]_async to asynchronously
1023 resolve. Affected files are lib/silcutil/silcnet.[ch].
1025 * Added support for rendering IPv6 based server, client and
1026 channel IDs. Affected file lib/silcutil/silcutil.c.
1028 * Added support for creating IPv6 based server IDs. Affected
1029 file is silcd/serverid.c.
1031 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1033 * Added silc_net_gethostby[addr/name] into the
1034 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1035 routines. Added silc_net_is_ip[4/6]. Affected file is
1036 lib/silcutil/unix/silcunixnet.c. All routines that take
1037 address as argument now supports both IPv4 and IPv6 addresses.
1039 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1041 * Fixed LIST command reply sending in server. Affected file
1044 * Server now sends the kicker's client ID in the KICK notify
1045 to the kicked client. Affected file silcd/command.c.
1047 * The client library now parses the kickers client ID and
1048 UI displays it. Affected files lib/silcclient/client_notify.c
1049 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1051 * Made all payload parsing function prototypes consistent.
1052 They all take now const unsigned char * and uint32 pair as
1053 the payload data instead of SilcBuffer. Changes all around
1054 the source tree. Other unsigned char* -> const unsigned char*
1055 changes around the tree as well.
1057 * Optimized SFTP client and server packet sending not to
1058 allocate new buffer for each packet but to recycle the
1059 first allocated buffer. Affected files are
1060 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1062 * Optimized the SFTP client to use SilcList instead of
1063 SilcDList for requests, because it is faster. Affected file
1064 is lib/silcsftp/sftp_client.c.
1066 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1067 into lib/silccore/silcid.[ch].
1069 Renamed silcpayload.[ch] into silcargument.[ch].
1071 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1073 * If client entry is deleted with active key agreement
1074 session, abort the session.
1076 The silc_client_abort_key_agreement now calls the completion
1077 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1079 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1082 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1084 * Don't use __restrict in older GCC's. Affected file is
1085 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1087 * silc_net_localhost now attempts to reverse lookup the
1088 IP/hostname. Affected file lib/silcutil/silcnet.c.
1090 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1091 command. It can be used to gain founder privileges at
1092 the same time when joining the channel.
1094 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1095 kicker's client ID as well. Updated protocol specs.
1097 Defined that the server must send SILC_COMMAND_IDENTIFY
1098 command reply with error status to client who sent
1099 private message with invalid client ID.
1101 Updated the protocol specification.
1103 * Added silc_server_send_command_reply to send any
1104 command reply. Affected file silcd/packet_send.[ch].
1106 * Added silc_id_payload_encode_data to encode ID payload
1107 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1109 * The server now send IDENTIFY command reply with error
1110 status if client ID in private message is invalid. Affected
1111 file silcd/packet_receive.c.
1113 * Save the server key file with server's IP address in
1114 the filename instead of hostname. The affected file is
1115 irssi/src/silc/core/client_ops.c.
1117 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1119 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1122 * Added libtool support for compiling shared objects in
1123 lib/silcsim. Affected file configure.in.pre and
1124 lib/silcsim/Makefile.am. Original patch by cras.
1126 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1128 * Pid file configuration, and server's config file fixes
1129 patch by toma. Updated CREDITS file.
1131 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1133 * Fixed silc_client_channel_message to not try to decrypt
1134 the message twice if it resolved the destination client
1135 information. This could cause of dropping one channel
1136 message. Affected file lib/silcclient/client_channel.c.
1138 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1140 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1141 lib/silcclient/client.c. This function is used when the SILC
1142 Client is run under some other scheduler, or event loop or
1143 main loop. On GUI applications, for example this may be
1144 desired to used to run the client under the GUI application's
1145 main loop. Typically the GUI application would register an
1146 idle task that calls this function multiple times in a second
1147 to quickly process the SILC specific data.
1149 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1151 * Fixed silc_server_drop() for dropping the supplementary
1152 groups as well, this could cause a security hole on some
1155 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1157 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1160 * Write PID file after dropping privileges. Added -F option
1161 to run server on foreground. A patch by debolaz.
1162 Affected files silcd/server.c, silcd/silcd.c.
1164 * Fixed MOTD to return the MOTD file server name. Affected
1165 file silcd/command.c.
1167 * Added INFO command reply handling to the Irssi SILC Client.
1168 Affected file irssi/src/silc/core/client_ops.c.
1170 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1172 * Fixed the silc_idcache_list_* routines to really support
1173 the dynamic list. Fixes a crash. Affected file is
1174 lib/silccore/silcidcache.c.
1176 * Fixed the LIST command reply to really call LIST command's
1177 pending callbacks. Affected file silcd/command_reply.c.
1179 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1181 * Update conn->local_entry->nickname after giving NICK
1182 command. Affected file lib/silcclient/command.c.
1184 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1186 * Added the [pid] option to the silcd configuration file
1188 Affected files: serverconfig.[ch] and silcd.c
1190 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1192 * Save fingerprint in WHOIS command reply in server.
1193 Affected file silcd/command_reply.c.
1195 * Fixed NICK commands pending callback registration.
1196 Affected file lib/silcclient/command.c.
1198 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1200 * Use ++server->cmd_ident when sending commands in server,
1201 instead of random number. Affected file silcd/command.c.
1203 * Fixed GETKEY command reply to call actually GETKEY pending
1204 command callbacks. Affected file silcd/command_reply.c.
1206 * A bit stricter check for nicknames. Check for same nickname
1207 in NICK command also. Affected file silcd/command.c.
1209 * Do not call INFO command everytime client ID changes, only
1210 during first connecting. Affected file lib/silcclient/client.c.
1212 * Set the new nickname only after successful command reply for
1213 NICK command is returned by server. Affected file
1214 lib/silcclient/command.c.
1216 * Remove nicknames from nicklist during server_signoff notify.
1217 Should fix /NAMES bit more. The affected file is
1218 irssi/src/silc/core/silc-channels.c.
1220 * Added `fingerprint' field to the SilcIDListData in the
1221 silcd/idlist.h to hold the fingerprint of the client's
1224 Send the fingerprint of the client's public key in WHOIS
1227 Affected files silcd/command.c, and silcd/idlist.[ch].
1229 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1230 create fingerprint from given data.
1232 * Show the fingerprint of the client's public key in WHOIS.
1233 Affected files irssi/src/module-formats.[ch] and
1234 irssi/src/silc/core/client_ops.c.
1236 * Format the multiple same nicknames also during JOIN and
1237 NICK_CHANGE notifys. Affected file is
1238 lib/silcclient/client_notify.c.
1240 * Do not print error on screen for invalid private message
1241 payload since it can come if someone is sending private
1242 messages with wrong key. Affected file
1243 lib/silccore/silcprivate.c.
1245 * Fixed multiple concurrent /PING crash. Affected file
1246 lib/silcclient/command.c.
1248 * Changed the wrong ID encoding. All IP addresses must be
1249 in MSB first order in encoded format. They were encoded
1250 wrong and was in LSB format. Affected files are
1251 silcd/serverid.c, lib/silcutil/silcutil.c.
1253 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1255 * Call the `connect' client operation through the scheduler
1256 in case of error. Affected file lib/silcclient/client.c.
1258 * Call the `failure' client operation even if the error
1259 occurred locally during a protocol. Affected file is
1260 lib/silcclient/protocol.c.
1262 * Added support of sending LIST command to router from normal
1263 server. This way normal server can get list of all channels
1264 in the network too. Fixed the channel list sending in the
1265 server too. Affected files are silcd/command.c, and
1266 silcd/command_reply.[ch].
1268 * Added silc_server_update_channels_by_server and
1269 silc_server_remove_channels_by_server. They are used during
1270 disconnection of primary router and in backup router protocol.
1271 Affected file silcd/server_util.[ch], silcd/server.c and
1272 silcd/server_backup.c.
1274 * Fixed channel adding to global list in IDENTIFY command
1275 reply in server. Affected file silcd/command_reply.c.
1277 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1279 * If the incoming packet type is REKEY or REKEY_DONE process
1280 that packet always synchronously. Fixes yet another MAC
1281 failed error on slow (dialup) connections. Affected file
1282 lib/silcclient/client.c and silcd/server.c.
1284 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1286 * Call check_version SKE callback for initiator too. Affected
1287 file lib/silcske/silcske.c.
1289 * Implemented fix for security hole found in the SKE that was
1290 fixed in the specification few days back; the initiator's
1291 public key is now added to the HASH value computation.
1292 Added backwards support for the old way of doing it too, for
1293 old clients and old servers. Affected file is
1294 lib/silcske/silcske.c.
1296 * Enabled mutual authentication by default in SKE. If initiator
1297 is not providing mutual authentication the responder will
1298 force it. This will provide the proof of posession of the
1299 private key for responder. The affected files are
1300 lib/silcclient/protocol.c and silcd/protocol.c.
1302 * Do not cache anymore the server's public key during SKE.
1303 We do mutual authentication so the proof of posession of
1304 private key is done, and if the server is authenticated in
1305 conn auth protocol with public key we must have the public
1306 key already. Affected file silcd/protocol.c.
1308 * Added new global debug variable: silc_debug_hexdump. If
1309 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1310 file lib/silcutil/silclog.[ch].
1312 * Fixed compilation warning due to char * -> const char *.
1313 Affected files lib/silcutil/silcnet.h, and
1314 lib/silccore/silcauth.[ch].
1316 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1318 * Fixed CMODE command when new channel key was created. If
1319 the creation failed the old key was removed. Next time giving
1320 same command would crash the server since the old key was
1321 freed already. Affected file silcd/command.c.
1323 * Fixed the silc_server_announce_get_channels to not crash
1324 on reconnect. Affected file silcd/server.c.
1326 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1328 * Added silc_log_set_debug_string function to set a regex
1329 string to match for debug output. Only the function names,
1330 or filenames matching the given debug string is actually
1331 printed. This way it is possible to filter out those debug
1332 strings that user is not interested in.
1334 Fixed a bug in silc_string_regexify.
1336 Affected files lib/silcutil/silclog.[ch], and
1337 lib/silcutil/unix/silcunixutil.c.
1339 * Changed the -d options in both server and Irssi SILC client
1340 to take the debug string as argument. Affected files
1341 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1343 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1345 * Added silc_hash_babbleprint to create a Bubble Babble
1346 Encoded fingerprint. The encoding is developed by Antti
1347 Huima (draft-huima-babble-01.txt), and it creates human
1348 readable strings out of binary data. Affected file
1349 lib/silccrypt/silchash.[ch].
1351 * Print the babble print now in addition of fingerprint as well
1352 in Irssi SILC client. Affected files are
1353 irssi/src/fe-common/silc/module-formats.[ch],
1354 irssi/src/fe-common/silc/core/client_ops.c.
1356 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1358 * Fixed a security problem found in SKE. The initiator's
1359 public key too is now added to the HASH hash value creation
1360 which is signed by the responder to create the SIGN value.
1361 This will prevent anyone in the middle to lie to the responder
1362 about the initiator's public key. If this is done now, the
1363 man in the middle will get caught. Updated the protocol
1366 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1368 * Better installation directory handling. Configure module
1369 paths and other paths automatically to example_silc* files
1370 in doc/. A patch by toma.
1372 * Fixed compiler warning from MPI library, and from SILC RNG.
1375 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1376 It can be configured with ./configure. A patch by toma.
1378 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1380 * Find correct make to use in prepare-clean. A patch by
1381 toma. Affected file prepare-clean.
1383 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1385 * Added irssi variables use_auto_addr, auto_bind_ip,
1386 auto_bind_port and auto_public_ip.
1388 * Changed the interface for silc_client_send_key_agreement
1389 in lib/silcclient/silcapi.h
1393 irssi/src/silc/core/silc-core.c
1395 lib/silcclient/silcapi.h
1396 irssi/src/silc/core/silc-channels.c
1397 lib/silcclient/client_keyagr.c
1400 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1402 * Added silc_pkcs_public_key_compare to compare two
1403 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1405 * Check that the client who set the founder mode on the
1406 channel is the same client that is giving the founder
1407 mode to itself. It is done by comparing the saved public
1408 key (it is saved even in the authentication is passphrase).
1409 Affected file silcd/command.c.
1411 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1413 * Do not process packet for disconnected socket connection.
1414 Affected file lib/silccore/silcpacket.c.
1416 * Process the DISCONNECT packet through scheduler in the
1417 client library. Affected file lib/silcclient/client.c.
1419 * Fixed the silc_client_packet_parse to not to increase
1420 the packet sequence number if the conn->sock and the
1421 current socket connection is not same. This can happen
1422 for example during key agreement when the conn includes
1423 multiple socket connections (listeners). Affected file
1424 lib/silcclient/client.c.
1426 * The sender of the file transfer request now provides also
1427 the pointer (listener) for the key exchange protocol. If
1428 the listener cannot be created then it sends empty key
1429 agreement and lets the receiver provide the listener.
1431 Added `local_ip' and `local_port' arguments to the
1432 silc_client_file_send. If they are provided they are used,
1433 if not then it will attempt to find local IP address, if
1434 not found or bind fails then the remote client will provide
1437 Affected files are lib/silcclient/client_ftp.c and
1438 lib/silcclient/silcapi.h.
1440 * Extended the FILE SEND command to support defining the
1441 local IP and port for key exchange listener. They are
1442 optional. Affected file irssi/src/silc/core/silc-servers.c.
1444 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1446 * Defined to WHOIS command reply the sending of fingerprint
1447 of the client's public key (if the proof of posession of the
1448 corresponding private key is verified by the server).
1449 Updated to the protocol specification.
1451 * Added support of receiving the client's public key's
1452 fingerprint in command reply in client library. Affected
1453 file is lib/silcclient/command_reply.c, and
1454 lib/silcclient/idlist.[ch].
1456 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1458 * Do not send over 128 chars long nickname to the server
1459 in NICK command. Affected file lib/silcclient/command.c.
1461 * Do not send over 256 chars long channel names to the server
1462 in JOIN command. Affected file lib/silcclient/command.c.
1464 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1466 * Assure that silc_server_close_connection cannot be called
1467 twice for same socket context. Affected file is
1470 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1472 * Send error message to application if opening file for
1473 writing during file transfer fails. Affected file is
1474 lib/silcclient/client_ftp.c.
1476 Remove all file transfer sessions for a client that we're
1477 removing from ID cache.
1479 Affected file is lib/silcclient/client_ftp.c.
1481 * Fixed silc_net_addr2bin to return correct address. Affected
1482 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1484 * Fixed file transfer session removing on signoff notify.
1485 Affected file irssi/src/silc/core/silc-servers.c.
1487 * Added the SilcClientFileError to be returned in the monitor
1488 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1489 Affected file lib/silcclient/silcapi.h.
1491 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1493 * Fixed a crash in silc_client_ftp_free_sessions and
1494 silc_client_ftp_session_free_client. Affected file
1495 lib/silcclient/client_ftp.c.
1497 * Added `disabled' field in the SilcChannelEntry in the server
1498 to indicate if the server entry is disabled. Affected file
1499 silcd/idlist.h, silcd/command[_reply].c.
1501 * SILC server adds now /var/run/silcd.pid everytime it is
1502 started. Affected file silcd/silcd.c.
1504 * Added silc_server_packet_send_clients to send a packet to
1505 the provided table of client entries. Affected file
1506 silcd/packet_send.[ch].
1508 * Fixed a crash in client resolving in client_prvmsg.c in
1509 client library. Affected file lib/silcclient/client_prvmsg.c.
1511 * Do not actually remove the client directly from ID cache
1512 during SERVER_SIGNOFF, but invalidate it. This way we
1513 preserve the WHOWAS info for the client. Affected file
1514 silcd/server_util.c.
1516 * Fixed SERVER_SIGNOFF notify handling in the server. The
1517 server is now able to process incoming SERVER_SIGNOFF notify
1518 for a server that it doesn't even know about. It will remove
1519 the clients provided in the notify. Affected file
1520 silcd/packet_receive.c.
1522 * Check for partial packet in data queue after every packet that
1523 was found from the queue. Return and wait for more data if
1524 there is partial data in queue. Affected file is
1525 lib/silccore/silcpacket.c.
1527 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1529 * Added SilcClietFileError enum to indicate error in
1530 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1531 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1532 Affected files lib/silcclient/silcapi.h and
1533 lib/silcclient/client_ftp.c.
1535 * Check that newsize in silc_buffer_realloc is larger than
1536 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1538 * Added better monitor of file transfers. It now monitors
1539 key agreement protocol during the file transfer too. Added
1540 error reporting too. Affected files
1541 irssi/src/silc/core/silc-servers.c,
1542 irssi/src/fe-common/silc/module-formats.[ch].
1544 * Wrote a help file for FILE command.
1546 * Added silc_rng_global_get_byte_fast to get not-so-secure
1547 random data as fast as possible. Random data is read from
1548 /dev/urandom if available and from the SILC RNG if not
1549 available. It is used in padding generation. Affected file
1550 lib/silccrypt/silcrng.[ch].
1552 * All packets in client library are now processed synchronously.
1553 Optimized packet processing a lot. Affected file
1554 lib/silcclient/client.c.
1556 * All server connection packets are processing synchronously
1557 now in server, to optimize packet processing. Affected file
1560 * Include files are installed now only in Toolkit distribution
1561 if make install is given. Affected files: all Makefile.am's.
1563 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1565 * Assure that silc_client_notify_by_server_resolve does not
1566 resolve the client information multiple times. If it cannot
1567 be found by the first it cannot be found at all. Affected
1568 file lib/silcclient/client_notify.c.
1570 * Fixed WHOWAS command reply calling. Affected file
1571 lib/silcclient/command_reply.c.
1573 * Removed all references to silc_idlist_get_client from the
1574 Irssi SILC client since that call is internal call used by
1575 the library. The Irssi SILC client will use now client
1576 retrieval functions found in silcapi.h.
1578 * Fixed a bug in resolving nickname info before sending
1579 private message. It used freed memory. Affected file
1580 irssi/src/silc/core/silc-servers.c.
1582 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1584 * Assure my_channels statistics cannot go negative in server.
1585 Affected files silcd/server.c, silcd/server_util.c.
1587 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1589 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1591 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1593 * Win32 Toolkit changes. Affected files
1594 win32/silc.dsw, win32/libsilc/libsilc.def,
1595 win32/libsilcclient/libsilc.def,
1596 lib/silcutil/silcutil.c, and
1597 lib/sftp/sftp_fs_memory.c.
1599 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1601 * Added silc_net_localip to return local host's IP address.
1602 Affected file lib/silcutil/silcnet.[ch].
1604 * If key exchange or rekey protocol is active for a connection
1605 parse all packets syncronously since there might be packets
1606 in packet queue that we are not able to process without first
1607 processing packets before them. Affected file silcd/server,
1608 lib/silcclient/client.c.
1610 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1611 whether library should continue processing the packet.
1612 Affected file lib/silccore/silcpacket.h.
1614 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1615 SilcSFTPMonitorData to SFTP server to monitor various
1616 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1617 lib/silcsftp/sftp_server.c.
1619 * Added silc_file_size to return file size. Affected file
1620 lib/silcutil/silcutil.[ch].
1622 * Implemented the file transfer support for the client library.
1623 Added preliminary support for simple client to client one-file
1624 transmission. Affected file lib/silcclient/client_ftp.c,
1625 lib/silccilent/client.[ch].
1627 * Added new local command FILE to the Irssi SILC Client.
1628 It is used to perform the file transfer. It has subcommands
1629 SEND, RECEIVE, SHOW and CLOSE. Affected files
1630 irssi/src/silc/core/client_ops.c,
1631 irssi/src/silc/core/silc-server.[ch].
1633 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1635 * Relay the SILC_PACKET_FTP in the server. Affected files
1636 silcd/server.c and silcd/packet_receive.c.
1638 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1640 * Renamed silc_file_read and silc_file_write to functions
1641 silc_file_readfile and silc_file_writefile. Added function
1642 silc_file_open and silc_file_close. Affected files
1643 lib/silcutil/silcutil.[ch].
1645 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1647 * Resolve the client info when received private message or
1648 channel message for a client which nickname we don't know.
1649 Affected files lib/silcclient/client_prvmsg.c and
1650 lib/silcclient/client_channel.c.
1652 * Do not crash in /KEY if client is not connected. Affected
1653 file irssi/src/silc/core/silc-channels.c.
1655 * Added SilcClientStatus field to the SilcClientEntry in the
1656 lib/silcclient/idlist.h.
1658 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1659 is incomplete and is being resolved, it won't be resolved
1662 Make sure also that USERS command reply does not resolve
1663 twice information. Affected file is
1664 lib/silcclient/command_reply.c.
1666 Make sure that silc_client_get_clients_by_list does not
1667 resolve twice same information.
1669 * Check for valid client->id in the silc_server_free_client_data.
1670 Affected file silcd/server.c.
1672 * Fixed /GETKEY nick@server not to crash if the server entry
1673 is not found. Affected file lib/silcclient/command.c.
1675 * Fixed the silc_server_check_cmode_rights to check the
1676 requested modes correctly. Affected file silcd/command.c.
1678 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1680 * Better checks for non-printable chars in nick added.
1681 Affected file silcd/command.c.
1683 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1685 * Call the silc_server_udpate_servers_by_server in the
1686 primary router that comes back online in the backup resuming
1687 protocol. Otherwise it routes packets wrong. Affected file
1688 silcd/server_util.[ch], silcd/server_backup.c.
1690 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1692 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1693 lib/silcutil/silcbuffmt.[ch].
1695 * Redefined the SILC packet header to include the padding
1696 length. Affected file lib/silccore/silcpacket.[ch].
1698 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1699 length for maximum padding up to 128 bytes). Affected
1700 file lib/silccore/silcpacket.h.
1702 * Removed all backwards support for old 0.5.x MAC thingies.
1703 The SILC packet header change makes it impossible to be
1704 backwards compatible.
1706 * Send the ENDING packet with timeout in the backup resuming
1707 protocol. This is to assure that all routers has connected
1708 to the primary router. Affected file silcd/server_backup.c.
1710 * Changed the RNG to take the first IV from random data. It
1711 used to take it from zero actually. Changed the RNG also
1712 to use /dev/urandom during session. /dev/random is used
1713 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1715 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1717 * Changed the SILC packet header to have the first two bytes
1718 (the packet length) encrypted. Affected files aroung the
1719 code tree, lib/silccore/silcpacket.[ch]. Removed the
1720 SilcPacketCheckDecrypt callback. It is not needed anymore
1721 since the silc_packet_receive_process will determine now
1722 whether the packet is normal or special.
1724 * Implemented the unidirectional MAC keys. Affected files
1725 lib/silcske/silcske.c, silcd/protocol.c and
1726 lib/silcclient/protocol.c.
1728 * Implemented the packet sequence number to the MAC computation.
1729 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1730 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1731 lib/silcclient/protocol.c.
1733 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1735 * Allow backup router to announce servers. All servers
1736 announced by backup router are added to the global list
1737 automatically. Update hte server's socket to our primary
1738 router also when backup router announces a server.
1739 Affected file silcd/packet_receive.c.
1741 * Do not update the client->router in the function
1742 silc_server_udpate_clients_by_server if the client is on
1743 global list. We might fail to find any specific server
1744 for locally connected clients and local cell clients. They
1745 should still use the `from' and not `to' as client->router.
1746 This fixes backup router resuming protocol. Affected file
1747 silcd/server_util.c.
1749 * Decrease channel statistics count only if the channel
1750 deletion worked. Affected files are silcd/server.c and
1751 silcd/server_util.c.
1753 * Added silc_server_update_servers_by_server to update origin
1754 of all server entries. Used during backup router protocol.
1755 Affected files silcd/server_util.[ch], silcd/server.c. and
1756 silcd/backup_router.c.
1758 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1759 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1760 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1761 lib/silccrypt/silchmac.c.
1763 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1765 * Assure that router cannot reroute the same channel message
1766 to the sender. Affected file silcd/packet_receive.c.
1768 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1770 * Made better checks that the channel message is not sent
1771 to the router it came from. Affected file is
1772 silcd/packet_send.c. Fixed memory leak too.
1774 * Announce informations for incoming router connection, but
1775 only after checking if it is replaced by backup router.
1776 Affected file silcd/packet_receive.c.
1778 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1780 * Fixed the backup resuming protocol to work in multiple
1781 router environment. Affected file silcd/server_backup.c.
1783 * Route packet only to one router in the function
1784 silc_server_packet_send_to_channel. Affected file is
1785 silcd/packet_send.c.
1787 * Fixed silc_server_send_notify_dest to set the broadcast
1788 flag. Fixed the silc_server_send_notify_topic to actually
1789 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1790 Affected file silcd/packet_send.c.
1792 * Changed the SFTP Filesystem interface. Changed the
1793 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1794 the filesystem operation function. The SilcSFTPFilesystem
1795 is now a context that is allocated by all filesystem allocation
1796 functions and it already includes the operations structure
1797 and filesystem specific context. It is given as argument
1798 now to the silc_sftp_server_start. This made the interface
1799 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1800 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1802 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1804 * Changed the backup router adding and getting interfaces
1805 in the server. The router that will be replaced by the
1806 specified backup router is now sent as argument. Affected
1807 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1810 * Added silc_net_addr2bin_ne to return the binary form of
1811 the IP address in network byte order. Affected files
1812 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1814 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1816 * Check for existing server ID in silc_server_new_server
1817 and in silc_server_connect_to_router_final and remove the
1818 old entry if it exists. Affected file silcd/packet_receive.c,
1821 * Send the channel message always to only one router, either
1822 in upstream or downstream. Affected file is
1823 silcd/packet_send.c.
1825 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1827 * Wrote the definition of the backup resuming protocol to the
1828 protocol specification.
1830 * Removed one redundant channel key generation from normal
1831 server during joining procedure. Removed one redundant
1832 channel key sending from server to router during joining
1833 procedure. Affected file silcd/command.c.
1835 * Made minor bugfixes to the backup router resuming protocol.
1836 Affected file silcd/server_backup.c, server.c.
1838 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1840 * Added --disable-asm configuration option. Affected files
1841 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1844 * Implemented the backup resuming protocol that is used to
1845 resume the primary router position in the cell after the
1846 primary router comes back online. Affected files
1847 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1848 and silcd/server_util.[ch].
1850 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1852 * Sleep two (2) seconds after sending QUIT command to server.
1853 Affected file lib/silcclient/command.c.
1855 * Assure that if outgoing data buffer is pending do not force
1856 send any data. Affected file silcd/packet_send.c.
1858 * Assure that if outgoing data buffer is pending do not force
1859 send any data. Affected file lib/silcclient/client.c.
1861 * Implemented the backup router support when the primary router
1862 goes down. The servers and routers can now use the backup
1863 router as new primary router without loosing connectivity.
1865 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1867 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1868 in the server to indicate disabled entry. All data read
1869 from the connection will be ignored and no data is sent
1870 for entry that is disabled. Affected files are
1871 silcd/idlist.h, silcd/server.c.
1873 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1875 * Created SFTP client and server test programs in the
1876 lib/silcsftp/tests directory.
1878 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1880 * Implemented memory filesystem (virtual filesystem) for
1881 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1884 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1886 * Implemented the SFTP (SSH File Transfer Protocol) to the
1887 lib/silcsftp. It includes SFTP client and SFTP server
1890 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1892 * Moved lib/silccore/silcprotocol.[ch] to the
1893 lib/silcutil library.
1895 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1896 take variable argument list pointer as argument. Affected
1897 file lib/silcutil/silcbuffmt.[ch].
1899 * Added silc_buffer_set function that is used to set data
1900 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1901 Affected file lib/silcutil/silcbuffer.h.
1903 * Changed various routines in the core library to use the new
1904 silc_buffer_set instead of allocating new buffer only for
1907 * Added 64-bit value formatting and unformatting support to the
1908 silc_buffer_[un]format routines. Affected file is
1909 lib/silcutil/silcbuffmt.[ch].
1911 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1912 to includes/bitmove.h.
1914 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1916 * Fixed channel user mode saving in client library. Affected
1917 file lib/silcclient/command[_reply].c.
1919 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1921 * Defined the file transfer to the SILC Protocol. Added
1922 new packet type SILC_PACKET_FTP and defined File Transfer
1923 Payload. The mandatory file transfer protocol is SFTP
1924 (SSH File Transfer Protocol). Affected file in addition
1925 of the internet draft is lib/silccore/silcpacket.h.
1927 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1928 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1929 is used as part of backup router protocol when the primary
1930 router of the cell is back online and wishes to resume
1931 the position as primary router.
1933 * Redefined the MAC generation keys in the protocol. The
1934 same key is not used anymore in both direction. Both
1935 direction will now use different keys for sending and
1936 receiving. This fixes a potential security flaw. This
1937 change causes incompatibilities in the protocol.
1939 * Redefined also the MAC computation from the packet.
1940 An packet sequence number is now added to the MAC
1941 computation. This prevents possible replay attacks against
1942 the protocol. This change too causes incompatibilities
1945 Added `sequence' field to the SilcPacketContext to hold
1946 the current sequence number for the packet.
1948 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1950 * Added `created' field to the SilcIDListData in the file
1951 silcd/idlist.h to indicate the time when the entry was
1954 * Added `created' field to the SilcChannelEntry too. Affected
1955 file silcd/idlist.h.
1957 * Added `creation_time' aguments to all the announcement functions
1958 in the server. If it is provided then only the entries that
1959 was created after the provided time frame are actually
1960 announced. Affected file silcd/server.[ch].
1962 * The protocol says that the Channel ID's IP address must be
1963 based on the router's IP address. Added check for this in
1964 the silc_server_new_channel when processing incoming New Channel
1965 Payload. Affected file silcd/packet_receive.c.
1967 * Print out the correct version with --version in SILC client.
1968 Affected file irssi/src/silc/core/silc-core.c.
1970 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1972 * Fixed WHOWAS command to check for completnes of the client
1973 entry always, not just when the command is coming from client.
1974 Affected file silcd/command.c.
1976 * Added new function silc_server_packet_queue_purge to purge the
1977 outgoing data queue to the network. After the function returns
1978 it is guaranteed that the outgoing packet queue is empty.
1979 Affected file silcd/packet_send.[ch].
1981 * Purge the outgoing packet queue in the rekey protocol's final
1982 callback to assure that all rekey packets go to the network
1983 before quitting the protocol. Affected file silcd/server.c.
1985 * Added silc_client_packet_queue_parse as similar function as
1986 in server to the client library. The affected file is
1987 lib/silcclient/client.c.
1989 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1991 * Splitted silcd/server.c and created silcd/server_util.[ch]
1992 for utility functions.
1994 * Added new socket flag SILC_SF_DISABLED to indicate that the
1995 connection is open but nothing can be sent to or received from
1996 the connection. Affected file lib/silcutil/silsockconn.[ch].
1997 The checking for disabled socket is checked in the low level
1998 silc_socket_write and silc_socket_read functions.
2000 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2002 * Allow only nicknames and channel names that fits into the
2003 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2005 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2007 * When processing JOIN command reply in server check that if
2008 the channel exists in our global list we'll move it the local
2009 list. Affected file silcd/command_reply.c.
2011 * Fixed the check whether client is joined on the channel already
2012 in JOIN command. Affected file lib/silcclient/command.c.
2014 * Fixed the JOIN command reply to check whether the channel
2015 already exists. Affected file lib/silcclient/command_reply.c.
2017 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2019 * Added silc_ske_status_string to map the SKE error numbers
2020 to readable strings. The affected files are
2021 lib/silcske/silcske[_status].[ch].
2023 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2025 * Do not show the private channels on the WHOIS channel list
2026 as it is not allowed by the protocol. The affected file is
2029 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2031 * Assure that the packet length digged from the actual packet
2032 is something sensible in the silc_packet_decrypt_rest_special
2033 in lib/silccrypt/silcpacket.c.
2035 * Free and NULL the allocated pointer in silc_hmac_alloc if
2036 the HMAC allocation fails. The affected file is
2037 lib/silccrypt/silchmac.c.
2039 * Print the selected security properties to the log files in
2040 the server. Affected file silcd/protocol.c.
2042 * Add SKE's reference counter even if calling the completion
2043 callback manually. Otherwise it goes negative, although it
2044 does not cause any problems. The affected file is
2045 lib/silcske/silcske.c.
2047 * Remove the client entry with short timeout after giving the
2048 KILL command. Affected file lib/silcclient/command.c.
2050 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2051 case all found clients are already disconnected (WHOWAS would
2052 found them) in the server. Affected file silcd/command.c.
2054 * Update the last_receive (time of last data received) to be
2055 updated only when received private or channel message so that
2056 the idle time showed in WHOIS makes more sense.
2058 * Added boolean field `valid' in to the SilcClientEntry in the
2059 client library to indicate whether the entry is valid or not.
2060 This fixes the nickname change bug on channel when changing
2061 the nickname to be same than the old (like nick to Nick) the
2062 nickname formatter doesn't set the new nick anymore to Nick@host.
2063 Affected file lib/silcclient/idlist.[ch].
2065 * Now actually fixed the nickname changing on disconnection.
2066 Added new function silc_change_nick to the Irssi SILC Client.
2067 Affected file irssi/src/silc/core/client_ops.c,
2068 irssi/src/silc/core/silc-nicklist.[ch].
2070 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2072 * Check that the public key exists in the GETKEY command before
2073 trying to encode it. Affected file silcd/command.c.
2075 * Print some notifications on received public keys with GETKEY
2076 command in the Irssi SILC Client. Affected files are
2077 irssi/src/fe-common/silc/module-formats.[ch],
2078 irssi/src/silc/core/client_ops.c.
2080 * Use IDENTIFY command to resolve the server information in the
2081 GETKEY command instead of INFO command. Affected file
2082 lib/silcclient/command.c.
2084 * All command reply functions in the client library now calls
2085 the pending command reply callbacks even if an error has
2086 occurred. The server has done this a long time and now it was
2087 time to move the client library to this as well. Now all
2088 errors can be delivered back to the pending command reply
2089 callbacks if necessary. Affected files are
2090 lib/silcclient/command[_reply].[ch].
2092 * Change the nickname on disconnection back to the username
2093 because in reconnect the server will enforce it to it anyway.
2094 Affected file irssi/src/silc/core/silc-servers.c.
2096 * Fixed a config file parsing bug in the Irssi SILC client.
2097 Affected file irssi/src/silc/core/clientconfig.c.
2099 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2101 * When printing the channel mode on JOIN, verify that the
2102 channel key and channel's HMAC are valid. Affected file
2103 irssi/src/silc/core/client_ops.c.
2105 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2107 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2108 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2109 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2111 * Removed channel key rekey task deleting from the function
2112 silc_server_save_channel_key. Affected file silcd/server.c.
2113 Added explicit timeout task context instead that is used to
2114 delete the task if we are registering a new task before the
2115 new task has elapsed.
2117 * When channel key rekey occurs the client library now saves
2118 the old channel key for a short period of time (10 seconds) and
2119 is able to use it in case some is still sending channel
2120 messages encrypted with the old key after the rekey. Affected
2121 file lib/silcclient/[idlist.h|client_channel.c].
2123 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2125 * Added check to the silc_server_new_id_real to not accept
2126 new ID if it is the sender's own ID. Affected file is
2127 silcd/packet_receive.c.
2129 * Assure that we do not announce ourself or the one we've
2130 sending our announcements when we're router and are announcing
2131 servers to our primary router. Affected file silcd/server.c.
2133 * Fixed silc_server_command_identify_check_client to assemble
2134 correct WHOIS packet. It send corrupted WHOIS packet and
2135 caused problem with router to router connections. Affected
2136 file silcd/command.c.
2138 Fixed also silc_server_command_whois_check the same way
2139 as for the IDENTIFY command.
2141 * Added new SilcIDListStatus to the server in the SilcIDListData
2142 structure. The status now includes the current status of
2143 the entry (like registered, resolved etc.). Affected file
2144 silcd/idlist.[ch]. Defined a bunch of different status types
2145 as well. This replaced the old boolean registered field as well.
2147 Added resolve_cmd_ident field to the SilcClientEntry structure
2148 too so that if the entry is for example being resolved so
2149 another command may attach to the same pending command reply
2150 without requiring to resolve the same entry again. This concept
2151 should optimize the WHOIS and the IDENTIFY resolving under
2152 heavy load by taking away unnecessary resolving for entries
2153 that are being resolved already.
2155 Added support for adding multiple pending commands for one
2156 command idenfier. Affected file silcd/command[_reply].[ch].
2158 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2159 before deleting the data. Otherwise the hash table will have
2160 freed data in comparison functions. Affected file is
2161 silcd/command_reply.c.
2163 * Fixed silc_idlist_replace_client_id to add the new entry to
2164 the cache with NULL nickname. Otherwise there will be invalid
2165 memory as the nickname after the nickname is freed. Affected
2166 file silcd/packet_receive.c.
2168 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2169 saved into wrong slots because the previous number of entries
2170 was not taken into account. Affected file silcd/idlist.c.
2171 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2173 * If we are router and we receive JOIN notify to a channel that
2174 does not have any users then notified client is marked as the
2175 channel founder, as it is it. The affected file is
2176 silcd/packet_receive.c
2178 * Added to the extended hash table API's table_del_*ext functions
2179 the destructor as argument too, so that the caller can decide
2180 which destructor to use or whether to use destructor at all.
2181 Affected file lib/silcutil/silchashtable.[ch].
2183 * Fixed ID Cache purging. It actually deleted the entries from
2184 the hash table after the data was freed. The hash table ended
2185 up comparing freed memory. The affected file is
2186 lib/silccore/silcidcache.c.
2188 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2190 * Fixed Irssi SILC client's KILL command's HELP syntax.
2192 * The USERS command now resolves the detailed user information
2193 if the userinfo field is missing. Affected file is
2194 lib/silcclient/command_reply.c.
2196 * Do not print error in silc_file_read if the read file does
2197 not exist. Just silently return NULL. Affected file is
2198 lib/silcutil/silcutil.c.
2200 * Fixed the silc_log_output to not wine about NULL filename
2201 and to not create some bogus " " filename. Affected file is
2202 lib/silcutil/silclog.c.
2204 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2206 * Fixed various printing bugs on the user interface in the
2207 Irssi SILC Client. Minor changes that were forgotten from
2210 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2212 * Fixed the configure.in.pre and the compilation and distribution
2213 environment to support the new autoconf 2.52. That version is
2214 now required to compile the CVS trunk.
2216 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2218 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2219 to generally parse user@fqdn format strings. Affected file
2220 lib/silcutil/silcutil.c.
2222 * Added nickname_format and nickname_force_format fields to the
2223 SilcClientParams structure. The first one defines the format
2224 for the nicknames that the library will enforce if the receives
2225 multiple same nicknames. The second one is boolean value and
2226 can be used to force the library to always enforce the format
2227 to the nicknames regardles whether there are multiple nicknames
2228 or not. This configurable formatting was employed to flexibly
2229 support accessing multiple nicknames from the user interface.
2230 The userinterface can now set the nicknames to what ever format
2231 they prefer. Affected file lib/silcclient/silcapi.h.
2233 Added function silc_client_nickname_format to the file
2234 lib/silcclient/idlist.c. It performs the nickname formatting.
2236 Added new field `hostname´ to the SilcClientEntry context.
2237 It holds the hostname of the client. Affected file is
2238 lib/silcclient/idlist.h.
2240 * Irssi SILC Client sets the nicknames in nick@hostn format.
2241 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2242 irssi/src/silc/core/silc-core.c.
2244 The WHOIS printing now also shows both the real nickname and
2245 the formatted nickname so that user knows how to access the
2246 user if there are multiple same nicknames cached. Affected
2247 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2248 printing formatting too to take the hostname now as a separate
2249 argument. The Affected file is
2250 irssi/src/fe-common/silc/modules-formats.[ch].
2252 * Changed the silc_client_get_clients_local to accept the formatted
2253 nickname as argument. It accepts the real nickname too but the
2254 formatted nickname can be used to find the true entry from
2255 multiple entries. Affected file lib/silcclient/silcapi.h and
2256 lib/silcclient/idlist.c.
2258 * Added nickname_format_parse field to the SilcClientParams.
2259 It is a callback function provided by the application to parse
2260 the nickname out of the formatted nickname string. The library
2261 calls it to get the nickname from the formatted string. Since
2262 the application generally knows better the format of the nickname
2263 string it parses it instead of the library, even though library
2264 encodes the formatted string. If the callback function is not
2265 provided then the library will use the string as is. The
2266 affected file is lib/silcclient/silcapi.h.
2268 * All the nickname strings passed to the client library in
2269 commands are now expected to be formatted nickname strings.
2270 If the command does not support the formatted nickname string
2271 it will assume that the sent string is the actual nickname.
2272 Affected file lib/silcclient/command.c.
2274 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2276 * Added public key authentication support to OPER and SILCOPER
2277 commands in the client library. Affected file is
2278 lib/silcclient/command.c.
2280 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2282 * Changed the get_auth_methdod client operation to be asynchronous.
2283 It can be async if the application resolves the authentication
2284 method from the server during the negotiation. Added new
2285 SilcGetAuthMeth completion callback that the application will
2286 call after resolving the authentication method.
2288 Added function silc_client_request_authentication_method that
2289 the application can use to resolve the authentication method
2290 from the server. Added also SilcConnectionAuthRequest callback
2291 that the library will call after the server has replied. The
2292 application can call this function if it does not know the
2293 current authentication method.
2295 Affected files are lib/silcclient/client.c and
2296 lib/silcclient/silcapi.h.
2298 * The Irssi SILC client now automatically resolves the authentication
2299 method incase any configuration information is not present (and
2300 currently there never is). The affected file is
2301 irssi/src/silc/core/client_ops.c.
2303 * Fixed public key authentication from the client library.
2304 Affected file lib/silcclient/protocol.c. Changed also the
2305 protocol specification about the public key authentication in
2306 the connection authentication protocol. The actual data to be
2307 signed is now computed with a hash function before signing.
2309 * Fixed the public key authentication from the server as well.
2310 Affected file silcd/protocol.c.
2312 * Removed the mlock()'s from the memory allocation routines.
2313 Affected file lib/silcutil/silcmemory.c. The ./configure does
2314 not check anymore for the mlock(). Affected file is
2317 * Fixed USERS command in server to allow the execution of the
2318 command for private and secret channels if the client sending
2319 the command is on the channel. Affected file silcd/command.c.
2321 * Fixed silc_client_get_clients_local to return the clients
2322 count correctly. It could return wrong value. Affected file
2323 lib/silcclient/idlist.c.
2325 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2327 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2328 types. The assembler optimizations seemed not to like 64-bit
2329 data types. The assmebler optimizations thus are now enabled
2330 also for BSD systems as opposed to only enable them for Linux.
2332 * Do not check for threads at all on BSD systems. Affected
2333 file configure.in.pre.
2335 * Removed -n and -h options from the Irssi SILC Client since
2336 they are not used in silc.
2338 * Fixed the prime generation to assure that the first digit
2339 of the generated random number is not zero since our conversion
2340 routines does not like number strings that starts with zero
2341 digit. If zero digit is seen the random number is regenerated.
2342 This caused some corrupted RSA keys when the zero first digit
2343 was met. Affected file lib/silcmath/silcprimegen.c.
2345 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2347 * Fixed WIN32 configuration in the ./configure script.
2348 Fixed to include xti.h on environments that has it.
2349 Patches by Carsten Ilchmann and andrew.
2351 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2353 * Changed the silc_id_create_client_id to be collision
2354 resistant. It is now assured that there cannot be created
2355 two same client ID's. I suspect that some weird bugs in
2356 the server were actually caused by duplicate Client IDs.
2357 Affected file silcd/serverid.[ch]. A router receiving
2358 new ID now also assures and informs the sending server
2359 if the ID caused collision.
2361 * Changed the silc_id_create_channel_id to also assure that
2362 there are no collisions.
2364 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2366 * Statement about ignoring the Mutual Authentication flag when
2367 performing rekey with PFS was a bit misleading. It is ignored
2368 if it was set in the initial negotiation, it cannot be even
2369 set in the rekey. Fixed in the ke-auth draft. Started the
2370 new versions of the protocol drafts in the doc/.
2372 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2374 * Fixed a bug in silc_client_command_identify_save when saving
2375 new channel information. The channel name was no duplicated
2376 and caused crash on exit. Affected file is
2377 lib/silcclient/command_reply.c.
2379 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2381 * Fixed the getkey command handling in the server. Send just
2382 empty OK reply to the sender if the key could not be fetched
2383 (but everything else was ok, like the key just was not available).
2384 Changed the public key parameter to optional in the protocol
2385 specs so that empty OK reply can be sent. Affected file
2388 Added a message to Irssi SILC client to tell to user if the
2389 server did not return a public key.
2391 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2393 * Fixed a channel key regeneration bug. It registered new
2394 timeout tasks exponentially until all system resources were
2395 used. Affected file silcd/server.c.
2397 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2399 * Added the SILC Document generator to the scripts/silcdoc.
2400 It can be used to generate the Toolkit Reference Manual out
2401 of the source tree. Internally it will also use the RoboDoc
2402 generator now imported in util/robodoc.
2404 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2406 * Added couple of return's in rekey protocol if error orccurred
2407 during the protocol. The execution must be terminated.
2408 Affected file silcd/protocol.c. Also, terminate the protocol
2409 always with timeout.
2411 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2413 * The client's Client ID was created initally from the wrong
2414 nickname (it could have been in format nick@host) in the
2415 silc_server_new_client. Affected file silcd/packet_receive.c
2417 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2419 * Added some SILC_LOG_ERROR's to various error conditions
2420 if client could not be added to ID cache. Affected files
2421 silcd/packet_receive.c and silcd/server.c.
2423 * When client's sock->user_data is freed, NULL also the
2424 client->router and client->connection pointers. Added check
2425 for these pointers being NULL to various places around the
2426 code. Affected file silcd/server.c.
2428 * Added client->data.registered == TRUE checks to various
2429 places around the code to assure that unregistered client's
2430 are not handled when it is not allowed. Affected file
2433 * Added `bool registered' fields to all
2434 silc_idlist_[server|client]_get_* routines to indicate whether
2435 the fetched client needs to be registered or not. Affected
2436 file silcd/idlist.[ch].
2438 * Add your own entry as registered to the ID cache in the
2439 server. Affected file server.c.
2441 * Fixed a bug in silc_server_new_server. The SilcServer was
2442 set as the new server's context instead of SilcServerEntry.
2443 This naturally caused some weird bugs.
2445 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2447 * Do not delete the channel rekey task when adding it
2448 for in silc_server_create_channel_key.
2450 * Changed the silc_server_create_channel_key to return
2451 TRUE or FALSE to indicate the success of the channel key
2454 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2456 * Fixed MSVC++ project files and added missing files to
2457 Makefiles under win32/.
2459 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2461 * Do not add TCP_NODELAY flag if the operating system
2462 does not have it defined. Affected files are
2463 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2465 * Fixed buffer overflow from Irssi SILC Client. Affected
2466 file irssi/src/fe-common/core/themes.c.
2468 * Fixed double free in client library in the file
2469 lib/silcclient/client.c when disconnecting from server.
2471 * Applied double free patch from cras to Irssi SILC client.
2472 Affected files irssi/src/core/[modules/expandos].c
2474 * Fixed the disconnection handling to Irssi SILC Client.
2475 The application must call silc_client_close_connection
2476 in ops->connect client operation in case of failure of
2477 the connection. Affected file is
2478 irssi/src/silc/core/client_ops.c.
2480 * Do not set sock->protocol to NULL in the function
2481 silc_client_close_connection after executing the protocol's
2482 final callback since the sock might not be valid anymore.
2483 Affected file lib/silcclient/client.c.
2485 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2487 * Do not enable SILC_THREADS if the linking with libpthread
2488 did not happen. Affected file configure.in.pre.
2490 * Added notion to protocol specification that server must
2491 verify the sent authentication payload with CMODE when
2492 setting the channel founder key. Implemented it to the
2493 server. Affected file silcd/command.c.
2495 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2497 * Added _EXTRA_DIST SILC distribution variable to the
2498 distributions file. It is used to conditionally add extra
2499 files or directories to the specific distribution. Affected
2500 files ./prepare, Makefile.am.pre and distributions.
2502 Removed the `_' from the start of the distribution names.
2505 * Added README.WIN32 for instructions to compile the Toolkit
2508 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2510 * Fixed a double free in disconnection in the server. Affected
2511 file is silcd/server.c.
2513 * Fixed the lib/silcske/groups.c to work now also with GMP
2514 MP library. The string conversion did not work when using
2515 specific base and the base is indicated in the string as well.
2517 * Created win32/ directory which now includes MSVC++ specific
2518 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2519 It will appear only in the toolkit distribution
2521 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2523 * Changed the key material distribution function in case when
2524 the hash output is too short. The data is now concatenated
2525 a bit differently than it used to. Made the change to the
2526 SKE protocol specification.
2528 * Added better GMP detection to configure.in.pre. A patch
2531 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2533 * Fixed a minor bug in SKE that might cause some problem on
2534 some platforms. Affected file lib/silcske/silcske.c.
2536 * Added the cookie checking for initiator in the SKE. It checks
2537 that the responder returns the sent cookie unmodified. The
2538 affected file is lib/silcske/silcske.c. Added new SKE
2539 error type INVALID_COOKIE that can be sent during the
2540 negotiation. Fixed some memory leaks as well.
2542 * Added the "invalid cookie" error message to Irssi SILC client's
2545 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2547 * Added `task_max' field to the SilcClientParams to indicate
2548 the maximum tasks the scheduler can handle. If set to zero,
2549 default values are used. Affected file lib/silcclient/silcapi.h.
2551 * Fixed memory leaks in silc_client_close_connection. Affected
2552 file lib/silcclient/client.c.
2554 * Added silc_client_del_client_entry to client library to free
2555 all memory of given client entry. Affected file is
2556 lib/silcclient/idlist.[ch].
2558 * Added new functions silc_client_del_channel and
2559 silc_client_del_server to delete channel and server entries.
2560 Affected file lib/silcclient/[silcapi.h/idlist.c].
2562 * Removed silc_client_del_client_by_id from silcapi.h.
2564 * Fixed the INFO command to return the server's own info
2565 correctly when querying by Server ID. Affected file is
2568 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2570 * Removed the non-blocking settings in WIN32 code in the
2571 silc_sock_[read/write] and added SleepEx instead. Affected
2572 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2573 of input data is now checked with FIONREAD and ioctlsocket.
2575 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2577 * Call silc_schedule_task_del_by_context in the
2578 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2579 Affected file lib/silccore/silcprotocol.c.
2581 * Call silc_protocol_cancel for active protocols in the
2582 silc_server_close_connection if the funtion
2583 silc_server_free_sock_user_data has not been called.
2584 Affected file silcd/server.c.
2586 * Generic tasks cannot be deleted using the del_by_fd
2587 task deleting function since generic tasks does not match
2588 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2590 * Added a notion to SILCOPER help file that the SILCOPER works
2591 only on router server, not on normal server.
2593 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2595 * Added for WIN32 support for the new scheduler as well.
2596 Affected file lib/silcutil/win32/silcwin32schedule.c.
2598 * Fixed the SHA1 implementation to work on various platforms.
2600 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2602 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2603 API. It is part of the scheduler now. Everything else is
2604 as previously but some functions has changed their names.
2605 Checkout the lib/silcutil/silcschedule.h for the interface.
2606 Updated all applications to use the new interface. Affected
2607 files are lib/silcutil/silcschedule.[ch].
2609 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Found a bug in the SKE implementation. The HASH value,
2612 specified by the protocol, was not computed correctly. The
2613 public key of the responder was not added to the computation
2614 even though it is mandatory. Affected file lib/silcske/silcske.c.
2615 This unfortunately causes incompatibilities with older
2616 clients and servers.
2618 * Added WIN32 specific network init and uninit functions:
2619 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2620 the Winsock2. Affected file lib/silcutil/silcnet.h and
2621 lib/silcutil/win32/silcwin32net.c.
2623 * Set the socket always to nonblocking mode on WIN32 after
2624 reading data or writing data. Affected file is
2625 lib/silcutil/win32/silcwin32sockconn.c.
2627 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2629 * Fixed various compilation problems under WIN32. Affected
2630 files lib/silcutil/win32/silcwin32thread.c and
2631 lib/silcutil/win32/silcwin32schedule.c.
2633 * Removed all _internal.h #includes from public header
2634 files. Internal headers must never be included from
2637 Removed also the lib/silcske/payload_internal.h file.
2639 * All include files that may be needed (public and some others
2640 included by the public headers) by application developers are
2641 now copied to the ./includes directory. It does not copy any
2642 internal headers. Affected file Makefile.defines.pre and all
2643 Makefile.am's under lib/ and subdirs.
2645 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2647 * Do not change the ~/.silc directory's permissions automatically.
2648 Affected file irssi/src/silc/core/clientutil.c.
2650 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2652 * Do not cancel the protocol in silc_server_close_connection
2653 it might cause recursion. Now cancelled in the function
2654 silc_server_free_sock_user_data. Affected file silcd/server.c.
2656 * Fixed the silc_server_remove_clients_by_server to regenerate
2657 the channel keys correctly finally. Added also new function
2658 silc_server_remove_clients_channels to actually do it.
2659 Affected file silcd/server.c.
2661 * Fixed the silc_server_new_channel to not crash by giving
2662 wrong router to the new channel. Affected file is
2663 silcd/packet_receive.c.
2665 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2667 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2668 which is given as argument to the silc_client_alloc now.
2669 It can be used to configure the client and set various parameters
2670 that affect the function of the client.
2672 * The USERS command in server did not check whether the channel
2673 is private or secret. Affected file silcd/command.c.
2675 * Added new argument to the USERS command in protocol specification.
2676 The USERS command now can take the channel name as argument
2677 as well. Added support for this in client and server and
2678 updated the protocol specs.
2680 * Completed the GETKEY command in client. It can be now used
2681 to fetch also servers public key not only some clients.
2682 Affected files lib/silcclient/command[_reply].c.
2684 * Added silc_client_get_server to return server entry by the
2685 server name. Affected files lib/silcclient/silcapi.h and
2688 * Redefined the IDENTIFY command in protocol specification to be
2689 more generic. It now can be used to query information about
2690 any entity in the SILC Network, including clients, servers and
2691 channels. The query may be based either the entity's name
2692 or the ID. Added support for this in both client and server.
2694 Affected files silcd/command.c and lib/silcclient/command.c
2695 and command_reply.c.
2697 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2698 the _from_client and _from_server functions. Affected file
2701 * Added silc_client_get_channel_by_id_resolve to the file
2702 lib/silcclient/silcapi.h to resolve channel information by
2703 its ID. Added also silc_client_get_channel_by_id that
2704 does not resolve it from the server.
2706 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2708 * Added SilcServerEntry context into the client library
2709 to represent one server. The INFO command now allocates
2710 these to save the resolved server info. For now on the
2711 client library will also keep information about servers,
2712 connected and resolved with INFO.
2714 The INFO command now allocates the SilcServerEntry context
2715 and saves the server info there. The COMMAND_REPLY in
2716 the INFO now returns the parameters to application in
2717 same order as defined in the protocol specification.
2719 The entries are cached in the client->server_cache.
2721 * The INFO command is now issued after received the Client ID
2722 from the server. Affected file lib/silcclient/client.c.
2724 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2725 to the application as the mode changer might be server.
2726 It is guaranteed that NULL is not returned anymore to the
2727 application. Affected file lib/silcclient/client_notify.c.
2729 The ID Type is now also passed to the application so that
2730 it can check whether the returned entry is SilcClientEntry
2733 Added new function silc_client_get_server_by_id to return
2734 the server entry by ID. Affected files are the
2735 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2737 * Do not create the channel in the Irssi SILC Client when issuing
2738 the JOIN command but when received the sucessful JOIN command
2739 reply. Otherwise the channel might get created even though we
2740 could not join it. The Affected file is
2741 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2743 * Fixed a channel joining bug in router. The router must also
2744 check the channel modes, invite and ban lists etc. when serving
2745 the JOIN command sent by normal server. Affected file is
2746 silcd/command.c. The router now resolves the client's
2747 information from the server who sent the JOIN command if it
2748 does not know it, and processes the JOIN command only after
2751 * Changed the SilcCommandCb to take new argument; void *context2.
2752 Affected file lib/silccore/silccommand.h
2754 The second argument in the command callbacks in the server now
2755 includes the SilcServerCommandReplyContext if the command was
2756 called as pending command callback from the command reply.
2757 Otherwise it is NULL. When called as pending the status of the
2758 command reply will be checked and if it was erronous the
2759 error will be sent to the original sender of the command.
2760 This way the client always receives the error messages even
2761 though the server was actually the one who received the error
2762 when it resent the command to router, for example. Affected
2763 files silcd/command[_reply].[ch].
2765 * Fixed sending WHOWAS command's error message to client if
2766 the requested client could not be found. It was missing.
2769 * Changed the CMODE and CUMODE commands reply arguments in the
2770 protocol specification. The Channel ID is now sent in both
2771 of the commands to identify the channel. Implemented this
2772 new feature to the client and server. Affected files
2773 lib/silcclient/command_reply.c and silcd/command.c.
2775 * Made better checks for invite and ban lists in the JOIN
2776 command in server. Affected file silcd/command.c.
2778 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2780 * The server now performs the incoming host IP/DNS lookup
2781 using the silc_socket_host_lookup and thus does not block
2782 the server anymore. Affected file silcd/server.c.
2784 * Completed the multi-thread support for SILC Scheduler in
2785 the lib/silcutil/silcschedule.c.
2787 * Fixed the configure.in.pre to detect the pthread correctly
2790 * Fixed a deadlock in silc_task_queue_wakeup in the file
2791 lib/silcutil/silctask.c.
2793 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2795 * Added new function silc_schedule_wakeup that is used in
2796 multi-threaded environment to wakeup the main thread's
2797 schduler. It needs to be used when a thread adds a new task
2798 or removes a task from task queues. After waking up, the
2799 scheduler will detect the task queue changes. If threads
2800 support is not compiled in this function has no effect.
2801 Implemented the wakeup mechanism to both Unix and WIN32
2802 systems. Affected files are lib/silcutil/silcschedule.[ch],
2803 lib/silcutil/unix/silcunixschedule.c and the
2804 lib/silcutil/win32/silcwin32schedule.c.
2806 * Added new function silc_task_queue_wakeup to wakeup the
2807 scheduler by the specified task queue. Affected file
2808 lib/silcutil/silctask.[ch].
2810 * The silc_socket_host_lookup_start now wakes up the scheduler
2811 after adding the timeout task. Affected file is
2812 lib/silcutil/silcsockconn.c.
2814 * The silc_socket_host_lookup is synchronous now if the threads
2815 support is not compiled in. However, the callback is still
2816 called asyncronously through the scheduler, anyway. Affected
2817 file lib/silcutil/silcsockconn.c.
2819 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2821 * Added new function silc_socket_host_lookup to perform
2822 asynchronous IP and FQDN lookups for the socket connection.
2823 Affected files lib/silcutil/silcsockconn.[ch].
2825 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2827 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2828 that may or may not compile the mutex support in.
2830 Changed the silc_mutex_alloc interface. It allocates the
2831 mutex now to the sent pointer and returns TRUE or FALSE.
2833 Affected file lib/silcutil/silcmutex.h.
2835 * Wrote the SILC Task Queue interface to support multi-threads.
2836 Affected file lib/silcutil/silctask.[ch].
2838 * Wrote the SILC Scheduler to support multi-threads. Affected
2839 file lib/silcutil/silcschedule.c.
2841 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2843 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2844 in lib/silcutil/win32/.
2846 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2848 * Defined SILC Mutex API and SILC Thread API and implemented
2849 them for Unix. Affected files are
2850 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2851 lib/silcutil/unix/silcunixmutex.c and
2852 lib/silcutil/unix/silcunixthread.c.
2854 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2856 * Fixed the silc_server_remove_clients_by_server's channel
2857 key re-generation. The hash table handling was incorrect
2858 and would not work with many channels. Affected file is
2861 * Fixed some memory leaks around the server code.
2863 * Rewrote the silc_server_get_users_on_channel to support IPv6
2864 based Client ID's. Affected file silcd/server.c.
2866 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2867 specification. However, a separate document must be written
2868 to define the detailed signing procedure and the payload
2869 associated with the flag. Defined the flag to the
2870 lib/silccore/silcchannel.h as well.
2872 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2874 * Changed the dynamic tables to static size tables in the
2875 lib/silccrypt/silchmac.c.
2877 * Removed GCC dependencies from the code. A patch by cras.
2879 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2881 * Do not show the error "Error receiving packet bla bla"
2882 in server if it really was not an error (-2 means that reading
2883 is pending). Affected file silcd/server.c.
2885 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2887 * Fixed a possible crash in silc_server_remove_clients_by_server
2888 in silcd/server.c. Fixed there also some memory leaks.
2890 * Fixed the silc_idlist_replace_client_id. It could replace
2891 wrong key in the hash table. Affected file silcd/idlist.c.
2893 * Do not check whether there are global users on the channel
2894 if the channel->global_users is FALSE. Affected functions
2895 silc_server_remove_from_one_channel and
2896 silc_server_remove_from_channels in silcd/server.c. Also,
2897 do not check if the removed client is local as we can be
2898 sure that global client was not removed from the channel
2899 and checking for global users is not needed.
2901 * The silc_server_remove_clients_by_server now re-generates
2902 the channel keys correctly for those channels that had
2903 clients removed from them. Affected file silcd/server.c.
2905 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2907 * Found the reason of random crashes in the server. We weren't
2908 ignoring the SIGPIPE signal (which can be sent in write())
2909 and it crashed the server. Affected file silcd/silcd.c.
2911 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2913 * Assure that sock->user_data is not NULL in the function
2914 silc_server_packet_send in silcd/packet_send.c.
2916 * Disconnect the remote connection if it could not be added
2917 to any ID lists in the server. The affected file is
2920 * Check in silc_server_packet_send[_real/dest] that the
2921 socket is not disconnecting and ignore the data if it is.
2922 Affected file silcd/packet_send.c.
2924 * Define inline to __inline on native WIN32 compilation.
2925 Affected file includes/silcwin32.h.
2927 * Added some explicit type casts for inline code since MSVC
2928 require them. Affected files lib/silcutil/silcbuffer.h,
2929 lib/trq/silcdlist.h and lib/trq/silclist.h.
2931 * Print warning in log files from now on if the packet
2932 decryption fails. Affected file silcd/server.c.
2934 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2936 * Changed the `say' client operation's interface to accept
2937 new `type' argument to indicate the type of the message sent
2938 by the library. The application may filter the library's
2939 messages according the type. The affected file is the
2940 lib/silcclient/silcapi.h.
2942 * Added two new functions to lib/silcclient/silcapi.h:
2943 silc_client_del_client and silc_client_del_client_by_id.
2944 Affected file lib/silcclient/idlist.c.
2946 * Moved the clientincludes.h from includes/ to silc/ and
2947 serverincludes.h from includes/ to silcd/.
2949 * The modes for the CMODE and CUMODE are now passed as
2950 uint32 for application with COMMAND_REPLY. The affected
2951 file is lib/silcclient/command_reply.c.
2953 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2955 * /WHOIS without arguments shows client's own information.
2956 Affected file lib/silcclient/command.c.
2958 * Changed PING to not accept any arguments. The specs
2959 says that client can ping only the connected server so
2960 requiring an argument is not needed. Affected file is
2961 lib/silcclient/command.c.
2963 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2965 * Fixed a fatal bug in private message sending and reception
2966 encryption and decryption when using private message keys.
2967 The implementation was incorrect and did not follow the
2968 specification. It causd that some of the message were
2969 lost since it did not use the sending and receiving keys
2970 as the protocol suggests. This has been fixed and will cause
2971 incompatibilities with older clients when sending private
2972 message encrypted with private message keys. Affected files
2973 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2974 and various other in Irssi SILC Client.
2976 Added `responder' boolean argument to the functions
2977 silc_client_add_private_message_key[_ske] to indicate when
2978 the key is added as responder or initiator of the key
2981 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2983 * Removed the silc_ske_check_version function and created
2984 a SilcSKECheckVersion callback. Added also a function
2985 silc_ske_set_callbacks that is now used to set all SKE
2986 callbacks. The callback functions are not given to
2987 the SKE functions anymore, but this function is used to
2990 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2992 * Added `silc_version' argument to the silc_client_alloc
2993 to define the version of the application for the library.
2994 The library will use the version string to compare it
2995 against the remote host's (usually a server) version
2996 string. Affected file lib/silcclient/silcapi.h
2998 * Added the KE protocol context to Key Agreement context
2999 in client library so that we can abort the SKE if it
3000 is in process when we get timeout. Affected file is
3001 lib/silcclient/client_keyagr.c.
3003 * Do not resolve the client ID forever if it returns in the
3004 first time that such client does not exist. This was done
3005 for example with private message. Affected file is
3006 lib/silcclient/client_prvmsg.c.
3008 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3010 * Do not add regex.h for WIN32. The affected file
3011 includes/silcincludes.h.
3013 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3014 not work yet 100%. It generates the DLL's automatically
3015 when compiling with --with-win32 under cygwin.
3017 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3019 * lib/contrib/regex.c is not compiled on WIN32.
3021 * Added silc_net_get_socket_opt function to the
3022 lib/silcutil/silcnet.h.
3024 * Added includes/silcwin32.h for WIN32 specific includes
3027 * Do not use ptime structure or any of the posix process
3028 functions on WIN32 in lib/silccrypt/silrng.c.
3030 * Added silc_gettimeofday to provide generic function
3031 for struct timeval on all platforms. Added the function
3032 to lib/silcutil/silcutil.h.
3034 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3036 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3037 library as they clearly belong there. As a plus side we
3038 can make the actual socket connection routines platform
3041 Added also new generic function silc_socket_read and
3042 silc_socket_write (that used to be silc_packet_[read/write].
3043 The implementation of these are platform specific.
3045 * Added WIN32 specific routines of silc_socket_[read/write]
3046 to lib/silcutil/win32/silcwin32sockconn.c.
3048 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3050 * Added preliminary support for native WIN32 compilation under
3051 cygwin (using the -mno-cygwin option for GCC) to the
3052 ./configure.in.pre. The --with-win32 now prepares the
3053 compilation for native WIN32.
3055 * Rewrote the SILC Scheduler interface in the file
3056 lib/silcutil/silcschedule.h. The scheduler is now context
3057 based and does not have anymore any global static scheduler.
3058 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3059 and created lib/silcutil/win32 directory for WIN32 based
3062 * Added Unix specific network routines to the
3063 lib/silcutil/unix/silcunixnet.c and the old
3064 lib/silcutil/silcnet.c includes now only generic routines.
3066 Added WIN32 specific network routines to the
3067 lib/silcutil/win32/silcwin32net.c.
3069 * Added Unix specific utility functions from the
3070 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3072 * Added WIN32 SILC Scheduler to the file
3073 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3076 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3078 * Do not handle JOIN notify in the server if the target client
3079 is not registered (idata->registered == FALSE). The affected
3080 file is silcd/packet_receive.c.
3082 * Update the nickrec->founder in event_cumode in the Irssi SILC
3083 client. Affected file irssi/src/silc/core/silc-channels.c.
3085 * Fixed the CUMODE_CHANGE notify handling in the server when
3086 server and router are announcing their clients on channels.
3087 Now the mode changes are saved and notified correctly. The
3088 affected file is /silcd/packet_receive.c.
3090 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3091 They really did not replace the cache entry in the ID Cache.
3092 Now they do that. Affected file silcd/idlist.c.
3094 * Fixed the KICK notify handling in the Irssi SILC client to
3095 update the channel records so that the kicked client does not
3096 appear to be on the channel. The affected file is
3097 irssi/src/silc/core/silc-channels.c.
3099 * Always update the conn->current_channel when executing command
3100 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3102 * Fixed the KILL notify handling in Irssi SILC client to remove
3103 the killed client on all channels.
3105 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3107 * Fixed the silc_parse_command_line to remove extra spaces
3108 from the start and end of the arguments. Affected file is
3109 lib/silcutil/silcutil.c.
3111 * Cancel and free any active protocol in the function
3112 silc_server_close_connection. Affected file silcd/server.c.
3114 * Cancel and free any active protocol in the function
3115 silc_client_close_connction. Affected file is
3116 lib/silcclient/client.c.
3118 * Do not execute the KILL command for clients that are in
3119 history (ie. they are not in the network). Affected file is
3122 * Fixed KILL notify handling, client does not crash anymore.
3123 Affected file irssi/src/silc/core/silc-channels.c.
3125 * Reduced the default packet buffer size from 2048 to 1024 in
3126 lib/silccore/silcpacket.c.
3128 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3129 counter to the SKE context that is incresed when the SKE library
3130 performs async operation outside the library. If the outside
3131 process frees the SKE context and FREED status will be set
3132 and the library will detect after the sync operation that the
3133 libary is freed. The affected files are
3134 lib/silcske/silcske[_status].[ch].
3136 * Resolve the client entry information in the function
3137 silc_client_channel_message to assure that NULL pointer is not
3138 passed as client entry to the application. */
3140 * Fixed the task timeout calculation to assure that there is
3141 never negative timeouts. The affected file is
3142 lib/silcutil/silcschedule.c.
3144 * Fixed the channel user mode notification sending in server.
3145 It was sent point-to-point to the router (or to server by router)
3146 but it needs to be destined to a channel. The routines now
3147 supports sending the channel user mode notifys to the channels
3148 when announcing clients and channels. Affected files are
3149 silcd/server.c and silcd/packet_receive.c.
3151 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3152 It did not actually replace the old channel entry in the cache.
3153 Affected file lib/silcclient/client_notify.c.
3155 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3157 * Fixed a possible crash in silc_packet_send_prepare. It now
3158 assures always that there is enough space in the buffer and
3159 at the tail area of the buffer (for MAC).
3161 Fixed the inbound buffer reallocation in silc_packet_read.
3162 It was old code and did not handle the reallocation correctly.
3165 The affected file is lib/silccore/silcpacket.c.
3167 * Fixed buffer overflow in silc_parse_nickname in the file
3168 lib/silcutil/silcutil.c.
3170 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3172 * make install generates new server keys only if there is not
3175 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3177 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3178 Added check that if the NOREPLY is set then we will not send
3179 the away message. This avoids infinite loop of away messages
3180 if both clients are away. The affected file is
3181 lib/silcclient/client_prvmsg.c.
3183 * Fixed client crash if /NICK was given without arguments.
3184 Affected file lib/silcclient/command.c.
3186 * Server does not send the invite list in INVITE command back
3187 to the client if the list was not altered. Added this notion
3188 to the protocol spec as well. Affected file silcd/command.c.
3190 Fixed possible crash in INVITE command by checking the
3191 value of silc_server_get_client_route command.
3193 * Fixed the INVITE notify type handling. The arguments are now
3194 taken in correct order and client does not crash. The affected
3195 file is irssi/src/silc/core/silc-channels.c.
3197 Removed the "Inviting xxx to channel" message from the
3198 client library away and let the application handle it.
3199 Affected file lib/silcclient/command.c. Added that message
3200 to Irssi SILC client's message formats.
3202 * Fixed CMODE command crash in client. It now checks the
3203 amount of arguments correctly and does not crash. The affected
3204 file is lib/silcclient/command.c.
3206 * Do not create new channel automatically in silc_channels_join
3207 but check whether the channel by that name already exists.
3208 Affected file irssi/silc/core/silc-channels.c.
3210 * Do not send the SERVER_SIGNOFF to router if the disconnected
3211 entity was the router. Affected file silcd/server.c.
3213 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3214 SILC client as it was missing from there.
3216 Added the handling of the KICK notify to the Irssi SILC client
3217 as it was missing. Added "you have been kicked" message to
3218 Irssi SILC client's message modules formats.
3220 Added the handing of the KILL notify to the Irssi SILC client
3221 as it was missing. Added the kill message module formats
3224 The affected file is irssi/src/silc/core/silc-channels.c.
3226 * The router did not save the channel mode the server announced.
3227 Affected file silcd/packet_receive.c.
3229 * Fixed a possible crash in INFO command in server. If the
3230 server did not provide the server info it crashed. Affected
3231 file silcd/command.c.
3233 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3235 * Fixed the GETKEY command in the server to check also the
3236 global list. Otherwise the GETKEY would not work correctly
3237 in normal SILC server. Affected file silcd/command.c.
3239 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3241 * Fixed GETKEY crash, it crashed if the command did not succseed.
3243 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3245 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3246 is now real and not just an macro interface to GMP.
3248 Removed the entire GMP from the source tree and imported new
3249 NSS MPI library instead. Reason for removing GMP is that it is
3250 extremely large and compiles extremely slow. The NSS MPI
3251 is only a few files and compiles in less than 10 seconds.
3252 The speed is also about the same as GMP. The MPI is imported
3253 to lib/silcmath/mpi.
3255 If the system has GMP installed we will still use the GMP.
3256 If it is not then the NSS MPI will be compiled.
3258 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3260 * Merged a long nickname (127 characters long) crash bugfix from
3261 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3263 * Merged a freed memory reference bugfix from Irssi CVS tree.
3264 Affected file irssi/src/core/commands.c.
3266 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3268 * Added the server's public key sving and verification to the
3269 server when performing the SKE. This was missing and the
3270 remote server's (or router's) public key was accepted without
3271 checking whether we have it previously or trust it at all.
3272 Affected file silcd/protocol.c.
3274 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3276 * Check in the silc_server_timeout_remote if protocol is active
3277 and make sure that the protocol's final callback is called so
3278 that all memory if freed. Affected file silcd/server.c.
3280 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3282 * silc_server_whois_send_reply crashed the server if the nickname
3283 was 127 characters long. Affected file silcd/command.c.
3285 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3287 * Added sanity check to the silc_server_new_client. If the hostname
3288 is provided inside username then check that the provided hostname
3289 really is the same as the resolved one. If the hostname was not
3290 resolved then check it from the public key. Affected file is
3291 silcd/packet_receive.c.
3293 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3294 if the server disconnected us and the connection is not valid
3295 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3297 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3298 the library to the lib/silcutil/silcutil.[ch].
3300 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Close log file after open. Affected file
3303 lib/silcutil/silclog.c.
3305 * Check whether sock == NULL in silc_client_send_packet and return
3306 if it is. Affected file lib/silcclient/silcclient.c.
3308 * Check rec->entry == NULL in the Irssi SILC Client before
3309 sending the channel message. Affecte file is
3310 irssi/src/silc/core/silc-servers.c.
3312 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3314 * Merged a splitted window bugfix from Irssi CVS tree. The
3315 affected file is irssi/src/fe-text/textbuffer-view.c.
3317 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3318 It did not print nickname.
3320 * Improved the distributions system a bit.
3322 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3324 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3325 irssi/src/fe-text/gui-window.c.
3327 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3328 to in-active server. The affected file is
3329 irssi/src/silc/core/client_ops.c.
3331 * Resolve the client in USERS command reply if the entry does
3332 not have username resolved. The affected file is
3333 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3334 command to WHOIS command to really resolve stuff. The USERS
3335 is not used any more in any critical section so WHOIS can
3336 be used even though it might be slower than IDENTIFY.
3338 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3341 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3343 * Changed the protocol API a bit more consistent in the
3344 lib/silccore/silcprotocol.[ch].
3346 * Changed the following headers to ROBODoc format:
3348 lib/silccore/silcpayload.h
3349 lib/silccore/silcprotocol.h
3350 lib/silccore/silcsockconn.h
3352 All core library headers are now formatted.
3354 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3356 * Fixed a bug in Irssi SILC client; do not show that you are
3357 server/router operator if you really are not. Affected file is
3358 irssi/src/silc/core/client_ops.c.
3360 * Renamed silc_command_free_payload to silc_command_payload_free.
3361 Affected file lib/silccore/silccommand.h
3363 * Added silcmath.h to include the prototoypes of various routines
3364 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3367 * Changed the following headers to ROBODoc format:
3369 lib/silccore/silcchannel.h
3370 lib/silccore/silccommand.h
3371 lib/silccore/silcid.h
3372 lib/silccore/silcidcache.h
3373 lib/silccore/silcmode.h
3374 lib/silccore/silcnotify.h
3375 lib/silccore/silcpacket.h
3376 lib/silcmath/silcmath.h
3378 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Added checking to the server code not to start the server if
3381 ciphers and stuff are not configured properly. Affected files
3382 silcd/serverconfig.[h] and silcd/server.c.
3384 * Changed the layout of the header files of the public interfaces
3385 in the SILC libraries. The new layout supports ROBODoc
3386 documentation tool (and some others) so that it is easy to create
3387 a library reference manual. All the other headers and source
3388 code must still follow the CodingStyle document. Also source
3389 code must not include these ROBODoc stuffs, only the headers.
3390 Furthermore, all public interface headers must now be named
3391 by using `silc' prefix, example: silcapi.h, silccipher.h.
3392 Some files were renamed due to this. All the other headers
3393 must not be used as public interfaces. I will update the
3394 CodingStyle document later. Changed following headers, so far:
3396 lib/silcclient/silcapi.h
3397 lib/silccore/silcauth.h
3398 lib/silccore/silcprivate.h
3399 lib/silccrypt/silcdh.h
3401 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3405 * Removed silc_client_packet_send_flush from the client library
3406 as it is not needed. Affected file lib/silcclient/client.[ch].
3408 * Added printing of message of unresolved authentication method
3409 to the Irssi SILC client. Added it to the module formats.
3410 Removed the same message from the client library.
3412 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3414 * Added new distribution feature, DISTLABEL. Every distribution
3415 can define own preprocessor label that can be used in the
3416 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3417 file distributions, acconfig.h.pre and prepare.
3419 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3421 * Added Makefile.defines_int to include the actual definitions
3422 for Makefile.defines.in. Tested the new distribution system,
3423 created distributions and tested installation.
3425 * Added AWAY message printing to the Irssi SILC client. Added
3426 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3428 * Added SCONNECT command to call the SILC's CONNECT command.
3429 Cannot use CONNECT directly since Irssi uses that internally.
3430 Affected file irssi/src/silc/core/silc-servers.c.
3432 Added ACTION local command. It is same as ME command but takes
3433 the channel as mandatory argument.
3435 Rewrote some of the Irssi's help files to suite for SILC
3438 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3440 * Added Makefile.defines[.in] that should for now on be included
3441 in all Makefile.am file in the source tree. That file includes
3442 all common compilation definitions for SILC source tree.
3444 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3446 * Minor changes to the ./prepare script to change the package
3447 name according the distribution name to the configure.in.
3449 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3451 * Created new distribution system. Added file `distributions'
3452 that defines all the distributions that can be created out of
3453 the SILC source tree. The ./prepare script now reads that
3454 file to determine how to prepare the distributions. The
3455 first argument to the ./prepare is the name of the distribution
3456 and second is the version of the distribution. If given
3457 without arguments it creates the default (toolkit) distribution
3458 with the default version (defined in ./prepare).
3460 All Makefile.am files that are subject to the distributions
3461 are now named as Makefile.am.pre. These are ./Makefile.am
3462 and lib/Makefile.am. Others may be changed later.
3464 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3466 * Added invite list, ban list, some key management and connection
3467 error message printing to module formats in the Irssi SILC client.
3469 * Added new silc_client_set_away_message to set the away message
3470 that is back to the person who sent private message. The
3471 affected file lib/silcclient/silcapi.h and the
3472 lib/silcclient/client_prvmsg.c.
3474 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3476 * Fixed the private message sending in the Irssi SILC client,
3477 added local command KEY to the Irssi SILC client.
3479 Added key management and key agreement message formats to the
3480 irssi/src/fe-common/silc/module-formats.[ch].
3482 Added USERS (alias WHO) printing, server/router operator
3483 indication and LIST command printing to the module formats.
3485 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3487 * Fixed channel joining notify handling, cumode notify handling
3488 from Irssi SILC client.
3490 * Added SILC specific module-formats to the Irssi SILC client so
3491 that SILC specific message hilighting, colors etc is possible.
3492 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3494 Added channel mode, channel user mode, actions, notices,
3495 whois and whowas printing to the the module-formats.c.
3497 * Fixed a bug in channel deletion in the server. The channel
3498 is not left to the cache even if the channel founder auth mode
3499 is set when there are no users anymore on the channel. Affected
3500 file silcd/server.c.
3502 * The silc_net_localhost now resolves the entire hostname including
3503 the domain name. Affected file lib/silcutil/silcnet.c.
3505 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3507 * Changed the ask_passphrase client operation to be ascynchronous.
3508 It has now a completion callback and a context that the
3509 application must call after it has got the passphrase from
3510 the user. Affected files lib/silcclient/silcapi.h,
3511 lib/silcclient/protocol.c, lib/silcclient/command.c and
3514 Added SilcAskPassphrase callback that the application calls
3515 to deliver the passphrase to the library.
3517 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3518 The public key verification and especially a certificate
3519 verification is asynchronous procedure.
3521 Added new SILC_SKE_STATUS_PENDING status to indicate the
3522 request is pending and a callback will be called to finalize
3525 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3526 indicate that remote end did not send its public key (or
3527 certificate), even though we require it. Added check for this
3528 condition in the SKE. This was a security bug, now fixed.
3530 Defined new SilcSKEVerifyCbCompletion callback that is called
3531 when the verification process is completed.
3533 The affected files lib/silcske/silcske_status.h and
3534 lib/silcske/silcske.[ch].
3536 * Changed the verify_public_key client operation to be async
3537 as well. Defined SilcVerifyPublicKey callback that is used to
3538 indicate the success of the public key verification process.
3540 Changed the server and client to use the new async client
3543 * Changed the Irssi SILC client's internal scheduler to be called
3544 twice as many times as it used to be. As a result the client
3545 should be a bit faster now. Affected file is
3546 irssi/src/silc/core/silc-core.c.
3548 * Added support to Irssi SILC client of asynchronous public key
3549 verification and passphrase inquiry. Affected file is
3550 irssi/src/silc/core/silc-core.c.
3552 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3554 * Do not say "You have left channel %s" in client library.
3555 Moved it to the application. Affected files are
3556 lib/silcclient/command.c and silc/client_ops.c.
3558 * Fixed silc_client_get_clients. Command context was not
3559 duplicated and was freed memory in the callback. Affected
3560 file lib/silcclient/idlist.c.
3562 * Do not say "you are now talking..." on JOIN command in the
3563 client library. The appliation must handle it.
3565 * Do not say ".. changed topic to" in command reply in the
3566 client libary. The application must handle it.
3568 * Fixed TOPIC command sending in the client library.
3570 * Fixed a memory leak in silc_client_command_free in the file
3571 lib/silcclient/command.c.
3573 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3575 * Imported a modified version of Irssi client to the source tree.
3576 The Irssi will be used to create a new client called
3577 Irssi SILC. Imported to irssi/.
3579 Added silc_core_init_finish function to the Irssi. Affected
3580 file irssi/configure.in.
3582 A lot changes in the Makefile.ams around the irssi tree.
3584 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3586 * Do not rehash if the new size is same as the old size of the
3587 hash table, in the silc_hash_table_rehash*. The affected file
3588 lib/silcutil/silchashtable.c.
3590 * Replaced hash_table_del_by_context calls from the server
3591 (when channel->user_list and client->channels) to the
3592 hash_table_del as it is sufficient and faster.
3594 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3596 * Added silc_hash_table_list, silc_hash_table_get and the
3597 SilcHashTableList structure to provide an alternative way to
3598 traverse the hash table. The affected files are
3599 lib/silcutil/silchashtable.[ch].
3601 * Changed the server's idlist routines to use the hash table
3602 routines to optimize the code.
3604 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3606 * Replaced the client entry's `channel' list and channel entry's
3607 `user_list' list to hash tables for optimized lookup. Changed
3608 the code to use the hash table interface around the code.
3609 Affected file lib/silcd/idlist.[ch].
3611 * Added `auto_rehash' boolean argument to the function
3612 silc_hash_table_alloc to indicate whether the hash table should
3613 auto-rehash when it thinks is appropriate time. It will
3614 increase the hash table size if the there is twice as much
3615 entries in the table than the size of the table, and will
3616 decrease the size if there are twice as less entries than
3617 the size of the table.
3619 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3621 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3623 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * silc_idcache_purge_by_context deletes the entry now by context
3626 as it is supposed to do. Affected file lib/silccore/idcache.c.
3628 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3629 client is not anymore valid (WHOWAS givens the info) and not
3630 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3632 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * Removed the `data' and `data_len' arguments from the ID Cache
3635 interfaces and added `name' argument. ID Cache does not handle
3636 anymore the binary data only a names associated with given ID.
3638 * When hashing a Client ID with silc_hash_id the entire ID is
3639 not hashed anymore, instead only the hash of the Client ID is
3640 hashed. This way we can access the Client ID from the cache
3641 with Client ID but with the hash of the ID (which is a hash of
3642 the nickname) as well without any difference in performance.
3644 Added also silc_idcache_find_by_id_one_ext to do one on one
3645 searching when we have the actual ID. Added also function
3646 silc_hash_client_id_compare. The affected files are
3647 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3649 * When hashing the name associated with a ID it is always done
3650 in lowercase. This way we can access the cache without worrying
3651 about case-sensitivity, even though, for example nicknames are
3654 * Fixed a bug in server with channel message sending. It put
3655 wrong ID type as destination ID. The affected file
3656 silcd/packet_send.c.
3658 * silc_idcache_del_by_context now deletes from all hash tables
3659 by context. Affected file lib/silccore/idcache.c.
3661 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3663 * Changed the client library to use the new ID Cache interface.
3664 Changes around the source tree.
3666 * Added silc_hash_table_rehash_ext to rehash with specific
3667 hash function. Affected file lib/silcutil/silchashtable.[ch].
3669 * Added silc_hash_string_compare to compare two strings in the
3670 hash table. Affected file lib/silcutil/silcutil.[ch].
3672 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3674 * Added new function silc_idcache_del_by_context into the
3675 lib/silccore/idcache.[ch].
3677 * Changed the server's ID list routines to use the new ID Cache
3678 interface. Changes around the source tree.
3680 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3682 * Added silc_hash_table_del[_by_context]_ext functions in to the
3683 lib/silcutil/silchashtable.[ch].
3685 Removed silc_hash_table_find_all* routines and added new
3686 silc_hash_table_find_foreach to replace them.
3688 Added silc_hash_table_replace_ext function as extended
3689 replacing function. Separated the simple hash table interface
3690 from the extended hash table interface in the file
3691 lib/silcutil/silchashtable.h.
3693 * Fixed minor bugs and changed it to use some of the new
3694 hash table functions in lib/silccore/idcache.c
3696 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3698 * Added new function silc_hash_table_find_all to return all keys
3699 in the hash table by the specified key. As the hash table is
3700 collision resistant it also makes it possible to have several
3701 duplicate keys in the hash table. This function may be used to
3702 find all of the keys from the hash.
3704 Added user_context arguments to the SilcHashFunction,
3705 SilcHashCompare and SilcHashDestructor to deliver user specified
3708 Added new fuctions silc_hash_table_find[_all]_ext to do
3709 extended lookup with specified hash and compare functions and
3710 specified user contexts.
3712 Added new function silc_hash_table_add_ext to add the key
3713 with specified hash function and user context.
3715 Added new function silc_hash_table_foreach to traverse all
3716 entrys in the hash table. Added SilcHashForeach callback
3719 Added new function silc_hash_table_del_by_context to delete
3720 the entry only if the context associated with the key matches.
3722 Affected files are lib/silcutil/silchashtable.[ch].
3724 * Removed silc_hash_[server/client/channel]_id and added just
3725 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3726 silc_hash_id_compare to compare two ID's using as the hash table
3727 comparison function. Added also silc_hash_data to hash
3728 binary data and silc_hash_data_compare to compare it.
3730 * Removed silc_idlist_find_client_by_hash as it is not needed
3731 anymore. Affected file silcd/idlist.[ch].
3733 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3734 to use internally the SilcHashTable. The new ID Cache is a lot
3735 faster than the old one. Some of the ID Cache interface was also
3736 rewritten and obsolete and stupid functions were removed.
3738 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3740 * Added entry_count field to the SilcHashTable to keep the number
3741 of the entries in the table. Implemented the function
3742 silc_hash_table_rehash. Added new function
3743 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3745 Fixed a minor bug in silc_hash_table_free.
3747 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3748 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3749 into the lib/silcutil/silcutil.[ch].
3751 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Implemented a collision resistant hash table into the
3754 lib/silcutil/silchashtable[ch]. See the header and the source
3755 for the SilcHashTable API.
3757 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3759 * Merged dotconf version 1.0.2 into lib/dotconf.
3761 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Do not compile anything in lib/silcsim/* if the SIM support
3764 is not enabled. The tree should now compile without problems
3767 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3769 * Compiled the SILC under cygwin. Compiled and tested briefly
3770 without problems. More tests needed. The SIMs didn't compile
3773 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3775 * Fixed possible crash in silc_get_username in the
3776 lib/silcutil/silcutil.c.
3778 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3780 * Fixed a va_arg in silc/client_ops.c.
3782 * Oops, RC5 routines were named AES and caused some problems
3783 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3785 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3787 * Added new SilcIDIP structure into the lib/silccore/id.h and
3788 replaced the old `ip' fields from all SILC ID's to that type.
3789 This is a step towards IPv6 support.
3791 The silc_id_get_len takes now the ID as an extra argument.
3792 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3793 both IPv4 and IPv6 based ID's.
3795 The affected files are lib/silccore/id.[ch] and other files
3796 around the tree using these routines.
3798 * Removed the ID length arguments in server from various
3799 silc_server_send_notify_* routines -> they are not needed
3802 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3804 * Fixed memory leak in silc_encode_pem_file in the file
3805 lib/silcutil/silcutil.c.
3807 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Check minor version as well in the SKE. Affected files are
3810 silcd/protocol.c and lib/silcclient/protocol.c.
3812 * Added --identifier option to the server so that an identifier
3813 can be when creating the public key for the server. Affected
3814 file is silcd/silcd.c.
3816 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3817 lib/silccrypt/silcpkcs.c.
3819 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Register default ciphers and stuff when using -C option with
3822 the server. Affected file sildc/silcd.c.
3824 * Put back the servers public key filename format, it is better
3825 than the new one. For now, the client keys are saved with the
3826 new filename format. The affected file silc/client_ops.c.
3828 * Implemented the Cipher API for the rest of the ciphers that
3829 did not implement it or implemented it the wrong way.
3831 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Register default ciphers and stuff when using the -S option
3834 in the client. Affected file silc/silc.c. Same also when
3835 creating new key pair with -C option.
3837 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3839 * Fixed the silc_verify_public_key client operation function to
3840 save the public keys differently. The fingerprint is now
3841 used as filename and not the hostname. This way also the
3842 client keys are saved uniquely and not with hostnames. The
3843 affected file is silc/client_ops.c.
3845 * Trimmed the silc_hash_fingerprint function to remove extra
3846 whitespaces from the end of the fingerprint. The affected
3847 file is lib/silccrypt/silchash.c.
3851 * Added silc_cipher_register_default function to register all
3852 default ciphers. It can be used when configuration files
3853 does not exist and the application does not want any specific
3854 ciphers in any specific order.
3856 The SilcDList is now used as silc_cipher_list dynamically
3857 allocated cipher list. Removed the static list all together
3858 and now all ciphers must be allocated to the dynamic list.
3859 The silc_cipher_alloc routine was changed to check only the
3862 All silc_cipher_* routines that used to return int returns
3865 The affected files lib/silccrypt/silccrypt.[ch].
3867 * The same thing was done to silc_hash_* as for silc_cipher_*
3868 routines. Affected files lib/silccrypt/silchash.[ch].
3870 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3871 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3872 Added also silc_pkcs_[un]register[_default] functions.
3873 Removed the data_context from the PKCS API.
3875 * Added silc_hmac_register_default function to register default
3876 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3877 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3878 to unregister all hmacs at once.
3880 * Register the default ciphers, hash functions, PKCSs and HMACs
3881 if client's configuration file does not exist. The affected
3884 * The client did not load the hash functions from the SIM
3885 modules at all. Added support for this. Affected file is
3886 silc/clientconfig.c.
3888 * When decoding public key with silc_pkcs_public_key_decode, check
3889 the supported algorithm only if PKCS are registered. Affected
3890 file lib/silccrypt/silcpkcs.c. The same was done with the
3891 silc_pkcs_private_key_decode.
3893 * Fixed the SILC List routines to keep the list always in order.
3894 It used to change the list's order when traversing the list but
3895 not it preserves the order. Affected file lib/trq/silclist.h.
3897 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3899 * Added the client library to use the SilcSocketConnection's
3900 reference counter (by silc_socket_dup) to prevent the bug that
3901 the socket object may be freed underneath async operation.
3903 * The name resolv library checking fixes in the configure.in.pre.
3906 * Created new version of the protocol drafts for future
3907 development. The -03 drafts are the ones that will be changed
3908 in the trunk now and the -02 will remain as they are.
3910 * Send list of CUMODE notifys to the router when announcing
3911 the channel users to the router. Affected file silcd/server.c.
3912 If the router receiving channel founder CUMODE for a channel
3913 that already has channel founder it will send CUMODE notify
3914 to the sender to remove the channel founder rights from the
3915 announced client. Affected file silcd/packet_receive.c.
3917 * The CUMODE notify may now use Server ID as well as the entity
3918 who changes the mode. Updated protocool specs.
3920 * Updated INSTALL and README files.
3922 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3924 * New web pages in the http://silc.pspt.fi. The pages was
3929 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3931 * Implemented the [DenyConnectin] config section in the server.
3932 Added silc_server_config_denied_conn to check whether incoming
3933 connection is denied. Affected file silcd/serverconfig.[ch].
3935 * Do not check the ports when checking the incoming configuration
3936 data if the port is 0, meaning any. Affected file is
3937 silcd/serverconfig.c.
3939 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3941 * Fixed buffer overflow in silc_string_compare in the file
3942 lib/silcutil/silcutil.c.
3944 * Fixed double free in silc_server_command_leave in the file
3947 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3949 * Fixed the version checking in the server. Affected file is
3952 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3954 * Fixed the configuration data fetching when accepting new
3955 connections in the server. Affected file silcd/server.c.
3957 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3959 * Added `sender_entry' argument to the function
3960 silc_server_packet_relay_to_channel so that we can check
3961 whether some destination actually belongs to the same route
3962 the sender belongs (ie, we must not resend the packet to the
3963 sender). Affected file silcd/packet_send.[ch].
3965 * Added `servername' field to the SilcClientEntry in the server
3966 to hold the name of the server where client is from. Affected
3967 file is silcd/idlist.h.
3969 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3971 * Moved the channel message encrypting in the router betwen
3972 router connections from silc_server_channel_message to the
3973 silc_server_packet_relay_to_channel since we want to check
3974 whether we have anybody channel before encrypting anything.
3975 Affected files silcd/packet_[receive/send].c.
3977 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * Fixed the [AdminConnection] server config section to support
3980 multiple entries. Affected file silcd/serverconfig.c.
3982 * Added support into the server to check the validity of the
3983 incoming connection before executing any KE or authentication
3986 * The connection configuration is now saved to the KE and
3987 connection auth protocol contexts and not fetched anymore in
3988 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3990 * The local hosts listenning address and port is also resolved
3991 now when starting the server. We want to have the socket object
3992 to include the real address and port for the listener. Added
3993 new function silc_net_check_local_by_sock into the files
3994 lib/silcutil/silcnet.[ch].
3996 * Fixed a broadcast bug in server -> do not broadcast if we
3999 * Fixed a routing bug. Do not route broadcast packets ever.
4000 Broadcast packets must be processed always and not routed since
4001 they may be destined to some other host than yourself and thus
4002 would get routed without no good reason. Affected file is
4005 * Added function silc_server_config_is_primary_route to check
4006 whether primary router connection has been configured (a router
4007 configuration that we are initiating). If there is not, we
4008 will assume that there is only two routers in the SILC network
4009 and we will use the incoming router connection as our primary
4010 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4012 * Changed the order of the broadcasting. Broadcast _after_ the
4013 packet has been processed not before. Affected file is
4016 * Fixed a [ClientConnection] parsing bug. The port was never
4017 parsed correctly thus resulting to port 0. Affected file
4018 silcd/serverconfig.c.
4020 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4021 argument and did not set the broadcast packet flag. Affected
4022 file silcd/packet_send.c. Fixed same bug in the function
4023 silc_server_send_notify as well.
4025 * If we receive NEW_ID packet for our own ID in the server, ignore
4028 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4032 * Removed the nickname from the Private Message Payload.
4033 Updated the code and the protocol specs.
4035 * Updated protocol specs for submitting to the IETF.
4037 * Tweaked the Random Number Generator a bit. Affected file
4038 lib/silccrypt/silcrng.c. Exported a new function
4039 silc_rng_[global]_add_noise which can be used to add more
4042 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4044 * Do not parse packets with different timeout when protocol
4045 is active -> may cause problem with rekey. Affected file
4048 * When server receives signoff notify it must not create
4049 new channel key if the client is on any channels since the
4050 sender of the signoff notify will create it.
4052 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4054 * Added printing of error messages during SKE protocol from the
4055 failure packet sent by server during SKE. Affected file
4058 * Removed the client's failure_callback handling with timeout
4059 and handle it immediately when received.
4061 * The SKE library returned wrong type in SUCCESS and FAILURE
4062 packets. They must be 32 bit MSB not 16 bit MSB.
4064 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4066 * Ok, rewrote the logic of the re-key and now it seems to work.
4067 I tested it on high traffic with frequent re-keys without
4068 problems. Added hmac_receive (and renamed hmac to hmac_send)
4069 in SilcClientConnection in lib/silcclient/client.h and
4070 in SilcIDListData in silcd/idlist.h. Also, removed the
4071 SilcPacketParserContext's cipher and hmac fields as they are
4072 not needed anymore and actually caused some problems when
4073 the ciphers and hmac's changed underneath the packet parser.
4075 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4077 * If re-key protocol is active then process the incoming packets
4078 synchronously since we must assure that icoming packets encrypted
4079 with the old key is processed before the new keys is set to
4080 use. This is true other packets than for REKEY packets.
4081 Affected file silcd/server.c. The same was done to client library
4082 as well, affected file lib/silcclient/client.c.
4084 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4086 * Fixed bug in client and server to accept the force send if
4087 the packet is send from silc_[server/client]_packet_process
4088 function. Otherwise the packets are never delivered, oops.
4090 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4092 * Disable force sending of packets when REKEY protocol is active.
4093 We must assure that no packet is sent directly when rekey is
4094 performed. All packets must be sent through packet queue.
4095 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4096 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4097 function is silc_[server/client]_packet_send_real to check
4100 * Replaced the SIM paths from example config files to
4101 /usr/local/modules. Also, make install creates now
4102 /usr/local/silc/logs directory to hold all the SILC server
4105 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

4116 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4118 * When MAC computation fails the silc_packet_decrypt returned 0
4119 even though it was supposed to return -1. Fixed this. The
4120 affected file is lib/silccore/silcpacket.c.
4122 * Do not replace the config files in /etc/silc (in make install)
4123 if they already exist. Affected file ./Makefile.am.
4125 * Do not send re-key packets immediately but through packet queue.
4126 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4128 * Changed silc_net_check_host_by_sock to return FALSE if the
4129 IP/DNS could not be resolved. Though, it returns the IP address
4130 now even if it could not resolve it (but returns also FALSE).
4131 Affected file lib/silcutil/silcnet.[ch].
4133 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4135 * Added silc_pkcs_decode_identifier to decode the public key's
4136 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4137 Added also silc_pkcs_free_identifier. Added also new context
4138 SilcPublicKeyIdentifier.
4140 * Added -S option to the silc client. It is used to dump the
4141 contents of the specified public key file.
4143 * Changed the PKCS api to return the public key length when
4144 setting the public key.
4146 * Fixed a fatal bug in the public and private key file loading.
4147 Affected file lib/silccrypt/silcpkcs.c.
4149 * Execute the packet parsing for client with zero (0) timeout
4150 if the protocol is active. Affected file silcd/server.c.
4152 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4154 * Made the key generation options to the silcd program. Added
4155 -C option, equivalent to client's option.
4157 * Added new [ServerKeys] config section to the server. It
4158 configures the server's public and private key.
4160 * Defined generic Public Key Payload into the protocol
4161 specification to send specific type of public keys and
4164 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4165 public key or certificate.
4167 * Implemented the GETKEY command to the server and to the
4168 client library and on user interface.
4170 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

4201 SilcClientConnection structure; not needed. Affected file is
4202 lib/silcclient/client.h.
4206 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4208 * Do not ask whether user wants to use the negotiated private key
4209 for private messages, just use it. Affected file is
4210 silc/local_command.c.
4212 * Added `send_enc_key' and `enc_key_len' fields to the
4213 SilcIDListData structure since they are needed in the re-key

4237 * Changed _ALL_ unsigned long and unsigned int to uint32,
4238 unsgined short to uint16 in the source tree.
4240 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4241 not handle clients that has entry->data.registered == FALSE.
4242 They are not in the network anymore. Affected file is
4245 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

4259 implemnted the printing of the SERVER_SIGNOFF info to the
4260 application. Affected file silc/client_ops.c.
4262 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4263 if the deleting was successful. Affected file silcd/idlist.[ch].
4265 * Added support for public key authentication in the connection
4266 authentication protocol in the client library. Affected file
4267 lib/silcclient/protocol.c.
4269 * Changed the server's silc_idlist_get_clients_by_* interface
4270 to support already allocated array so that new entries may be
4271 added to pre-allocated array. Affected file silcd/idlist.[ch].
4272 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4273 and command replies.
4275 * All command reply functions in the server now calls the
4276 pending command callback even if error occured. This way the
4277 error will be delivered to the client as well. Affected files
4278 silcd/command.c and silcd/command_reply.c.
4280 * Fixed INFO command to return local server's info if no server
4281 was provided. Affected file lib/silcclient/command.c.
4283 * Removed RESTART command for good. Updated the code and the
4286 * Rewrote parts of the task system. It is a bit simpler now.
4287 Removed unsued task priorities. The affected files are
4288 lib/silcutil/silctask.[ch].
4290 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4292 * Moved the USERS printing from the library to the application.
4293 Affected files lib/silcclient/command.c and silc/client_ops.c.
4295 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4299 * Added channel key re-key support. The re-key is perfomed
4300 only by the router and is done once in an hour. Added `rekey'
4301 field to the SilcChannelEntry in the server. Affected files
4302 silcd/server.c and silcd/idlist.h.
4304 * Added silc_task_unregister_by_context into the file
4305 lib/silcutil/silctask.[ch].
4307 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4309 * Added SILC_UMODE_GONE mode to indicate when the client is not
4310 present in the SILC network. Added also support to the local
4311 command AWAY that will set this mode. Added support of showing
4312 "xxx is gone" in WHOIS command. The USERS command shows the
4313 gone status as well.
4315 * Fixed setting server and router operator privileges in the
4316 server's UMODE command. Affected file silcd/command.c.
4318 * Merged the SKE KE1 and KE2 payloads into one payload. The
4319 new KE payload is equivalent to the old KE2 payload.
4321 Cleaned up the SKE Start Payload parsing. It now uses the
4322 simple buffer unformatting to do the parsing. A lot faster
4325 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4326 to the SKE that is used to indicate whether both of the SKE
4327 parties should perform authentication. By default only the
4328 responder performs authentication. By setting this flag also
4329 the initiator must do authentication. By default it is unset
4330 since in normal SKE case, client to server connection, only
4331 the responder should do authentication. When doing SKE between
4332 two clients both should perform authentication. Updated the
4333 code and the protocol specs.
4335 * A little fix to IDENTIFY command in the server. Search the
4336 client first by hash not nickname. Affected file is
4339 * Fixed the silc_client_close_connection to support closing
4340 the client to client connections wihtout deleting too much
4341 data. Affected file lib/silcclient/client.c.
4343 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4344 are received if protocol used to be active but is not anymore
4345 the application would crash due to NULL pointer dereference.
4346 Affected files silcd/server.c and lib/silcclient/client.c.
4348 * Added `hash' field to the SilcClientConnection to include
4349 the hash function negotiated in the SKE protocol.
4351 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4352 to set the channel founder authentication data. A client can
4353 claim the founder rights later by providing the authentication
4354 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4355 This way the channel founder can regain the channel founder
4356 privileges even it is left the channel. This works only on
4357 local server and the client must be connected to the same
4358 server to be able to regain the founder rights. Updated the
4359 protocol specs accordingly.
4361 Added support to the CMODE command in the client to set the
4362 founder auth data. Read the README to see how to set it.
4364 Added support to the CUMODE command to claim the founder
4365 rights. Read the README to see how to do it.
4367 Added support for the founder authentication to the Channel
4368 Entry in the server. Affected file silcd/idlist.h.
4370 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4371 server's CMODE command. Affected file silcd/command.c.
4373 * Added the following new functions into lib/silccore/silcauth.[ch]:
4374 silc_auth_get_method and silc_auth_get_data.
4376 * The server now saves the remote hosts public key to the
4377 SilcIDListData pointer. Affected file silcd/protocol.c.
4379 * The normal server now does not remove the channel entry from
4380 the cache if the founder authentication data is set. It used
4381 to remove it if the founder was the last one on the channel on
4382 the server and left the channel. The auth data is saved and
4383 if the channel is re-joined later the old entry is used with
4384 the old auth data. Affected files silcd/command_reply.c and
4387 * Removed the `pkcs' field from the SilcIDListData structure
4388 in the server; it is not used. Affected file silcd/idlist.h.
4390 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4392 * Fixed packet processing on slow links. Partial packets were
4393 never re-processed because the incoming data buffer was cleared
4394 by the application. Application must not directly clear the
4395 sock->inbuf, the packet processing routines handle it. Fixed
4396 this in client library and in server.
4398 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4400 * Fixed the WHOIS and IDENTIFY send reply function to really
4401 check whether to send list or just one entry. Affected file
4404 * Cleaned up the LEAVE command's channel key distribution. The
4405 affected file silcd/command.c.
4407 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4408 can enforce the channel mode as well. In that case the ID
4409 includes the ID of the server. The code now enforces the
4410 mode change if the router have different mode than the server.
4412 * The notify client operation with CMODE_CHANGE notify can now
4413 return NULL client_entry pointer if the CMODE was not changed
4414 by client. Application must check for this.
4416 * Added <Server ID> argument to INFO command to support server
4417 info fetching by Server ID.
4419 * Added silc_server_announce_get_channel_users to get assembled
4420 packets of channel users of the specified channel. Affected
4421 file silcd/server.[ch].
4423 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4424 was freed underneath the ID Cache.
4426 * Re-announce clients when the server received CHANNEL_CHANGE
4427 notify from the router. Affected file silcd/packet_send.c.
4429 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4431 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4432 crashed since it did not handle the fact that there is no cipher
4433 called "3" and didn't check the error condition. Now fixed.
4435 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4436 flag. It can be used to send message requests.
4438 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4440 * Implemented the RESTART command in the client.
4442 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4443 notice type messages. Added notice printing to the user
4446 * The channel keys are not re-generated if the channel's mode
4447 is PRIVKEY, ie private key on the channel exists. Affected
4448 files silcd/server.c and silcd/command.c.
4450 * Fixed a little bug in channel message delivery when channel
4451 private keys are set in the server. Affected file is
4452 silcd/packet_send.c.
4454 * Changed the setting on channel->on_channel = TRUE from the
4455 silc_client_save_channel_key to the JOIN command reply. The
4456 key payload is not received if the private channel key is set.
4457 Affected file lib/silcclient/command_reply.c and the
4458 lib/silcclient/client_channel.c.
4460 * When the CMODE_CHANGE notify is sent and the channel private
4461 key mode is removed the channel key must be re-generated in
4462 other cells as well. Added this support for the router in the
4463 silcd/packet_receive.c.
4465 * Added new local command NOTICE to send notice message on
4466 channel. Affected file silc/local_command.[ch].
4468 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4470 * Added new local command ME to the client. It is used to send
4471 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4472 some action. Affected file silc/local_command.[ch].
4474 * Changed channel_message and private_message client operations
4475 to deliver the message flags to the application. Added also
4476 the `flags' arguments to the silc_client_send_channel_message
4477 and silc_client_send_private_message functions. Affected file
4480 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4482 * Redefined the Private Message Payload to support private message
4483 keys and to support the new private message flags. Updated
4484 the protocol specs. Flags makes it possible to have for example
4485 CTCP style messages.
4487 * Added new type SilcPrivateMessagePayload and defined an API
4488 for it in the lib/silcclient/silcprivate.[ch].
4490 * Tested private message private keys successfully. Tested the
4491 private message key set, unset and list commands with the new
4494 * Redefined the Channel Message Payload to include the channel
4495 message flags (equal with private message flags) to support
4496 for example CTCP style messages.
4498 * Defined some of the message (for channel and private message)
4499 flags. Updated the protocol specs and added the flags to the
4500 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4502 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Added SilcKeyAgreementStatus type to the key agreement routines
4505 to indicate the current status and error if one occured.
4506 The status types are defined in the lib/silcclient/silcapi.h.
4508 * Added new local command KEY that is used to set and unset private
4509 keys for channels, set and unset private keys for private messages
4510 with remote clients and to send key agreement requests and
4511 negotiate the key agreement protocol with remote client. The
4512 key agreement is supported only to negotiate private message keys,
4513 it currently cannot be used to negotiate private keys for channels,
4514 as it is not convenient for that purpose.
4516 * Fixed a minor pending callback setting bug in the function
4517 silc_client_get_client_by_id_resolve, now the function works.
4518 Affected file lib/silcclient/idlist.c.
4520 * Added function silc_net_get_local_port to get local bound
4521 port by socket. Added to lib/silcutil/silcnet.[ch].
4523 * Added `sockets' and `sockets_count' fields to the SilcClient
4524 object. They hold the sockets of the listenning sockets in
4525 the client. Listenning sockets may be for example the key
4526 agreement server. Affected file lib/silcclient/client.[ch].
4527 Added functions the silc_client_add_socket and the
4528 silc_client_del_socket. They are exported to the application
4531 * Added ~./silc/clientkeys to support other client's public keys.
4533 * Renamed verify_server_key client operation to verify_public_key
4534 and added one argument to indicate the type of the connection
4535 (server, client etc.).
4537 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Added silc_server_connection_auth_request to handle the
4540 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4541 silcd/packet_receive.[ch].
4543 * Added silc_server_send_connection_auth_request into the
4544 silcd/packet_send.c to send the connection auth request packet.
4546 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4549 * Fixed the public key authentication in responder side in the
4550 server. The `auth_data' pointer includes the SilcPublicKey
4551 not the path to the public key. Affected file silcd/protocol.c.
4553 * Implemented the public key authentication in the initiator side
4554 in the server. Affected file silcd/protocol.c.
4556 * Removed the [RedirectClient] config section from the server
4557 configuration. Is not needed and I don't want to implement it.
4559 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4561 * Cleaned up the CMODE command in the server. It now works
4562 correctly and supports all the modes defined in the protocol.
4563 Affected file is silcd/command.c.
4565 * Added `hmac_name' field to the SilcChannelEntry in the server
4566 to hold the default HMAC of the channel. It can be set when
4567 creating the channel (with JOIN command). Affected files
4570 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4571 type to indicate the change of the current cipher and hmac
4572 on the channel. Client can safely ignore the <cipher> argument
4573 (if it chooses to do so) since the CHANNEL_KEY packet will
4574 force the channel key change anyway. The <hmac> argument is
4575 important since the client is responsible of setting the new
4576 HMAC and the hmac key into use.
4578 * Fixed the CMODE command in the client library as well.
4580 * Tested CMODE command in router environment successfully.
4582 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4584 * Show the version of the remote client (or server) when connecting
4585 to the server. It is logged to the log file. Affected file
4586 is silcd/protocol.c.
4588 * Fixed the KILLED notify handling in the client library. The
4589 client must be removed from all channels when receiving the
4592 Also, do not remove the client entry when giving the KILL
4593 command but when the KILLED notify is received.
4595 * Removed silc_idlist_find_client_by_nickname from the server.
4596 Not needed anymore. Affected files silcd/idlist.[ch].
4598 * Implemented the CHANNEL_CHANGE notify type handling to the
4599 server. Affected file silcd/server.c.
4603 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * Added silc_server_send_notify_invite to send the INVITE
4606 notify between routers.
4608 * Implemented the INVITE command correctly to the server.
4610 * Implemented the INVITE notify type handling in the server.
4612 * Implemented the INVITE command to the client library and on the
4615 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4617 * Added function silc_server_get_client_resolve to find the
4618 client entry by ID from all ID lists and then resolve it
4619 (using WHOIS) if it cannot be found. Affected file is
4622 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4624 * Implemented the BAN command to the client library.
4626 * The JOIN command in the server now checks the invite list
4629 * Changed the silc_command_reply_payload_encode_va and the
4630 silc_command_payload_encode_va to support that if argument is
4631 NULL it ignores and checks the next argument. Affected file
4632 lib/silccore/silccommand.c.
4634 * Added silc_server_send_notify_ban to send the BAN notify
4635 type between routers.
4637 * Chaned the silc_notify_payload_encode to support that if
4638 argument is NULL it ignores and checks the next argument.
4639 Affected file lib/silccore/silcnotify.c.
4641 * Tested ban lists in router environment successfully.
4643 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4645 * Implemented BAN command to the server, in silcd/command.[ch].
4647 * Removed the BAN and INVITE_LIST modes from the CMODE command
4650 * Added function silc_string_match to regex match two strings.
4651 Affected files lib/silcutil/silcutil.[ch].
4653 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4655 * Redefined parts of the SilcChannelEntry in the server to support
4656 the new ban and invite lists.
4658 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4660 * Redefined the INVITE command. The same command can be used to
4661 invite individuals to the channel but also to manage the invite
4662 list of the channel (to add to and remove from the invite list).
4663 Updated the protocol specs.
4665 * Added new command SILC_COMMAND_BAN that can be used to manage
4666 the ban list of the channel. Updated the protocol specs.
4668 * Removed the channel modes: the SILC_CMODE_BAN and the
4669 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4670 in the CMODE command. The equivalent features are now available
4671 using INVITE and BAN commands. Updated the protocol specs.
4673 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4674 in the network about change in the current ban list. The notify
4675 type is not used by the client.
4677 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4678 support the invite lists.
4680 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4682 * Added new function silc_string_regexify that converts string
4683 including wildcard characters into regex string that can
4684 be used by the GNU regex library. Added into the file
4685 lib/silcutil/silcutil.[ch].
4687 Added silc_string_regex_combine to combine to regex strings
4688 into one so that they can be used as one regex string by
4689 the GNU regex library. Added into the file
4690 lib/silcutil/silcutil.[ch].
4692 Added silc_string_regex_match to match two strings. It returns
4693 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4695 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4697 * Imported GNU regex to the soruce tree into lib/contrib.
4698 Fixed some compiler warning from the regex.c.
4700 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * Fixed MOTD command in the server to work in router environment.
4704 * Fixed the MOTD command in the client library to support
4705 the server argument in the command.
4707 * Added `nickname_len' argument to the silc_idlist_add_client
4708 in the server, as the `nickname' argument may be binary data
4711 * Added silc_idlist_get_channels to return all channels from
4714 * Implemented LIST command to the server. Affected file is
4717 * Implemented the LIST command to the client library and on the
4720 * Added [<user count>] argument to the LIST command reply.
4721 With private channels the user count is not shown.
4723 * Updated TODO and README.
4725 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4727 * The client entry's data.registered must be TRUE even with
4728 global client entry on global client list. The data.registered
4729 is used to check whether the client is anymore in the network,
4730 for example with WHOWAS command so it must be valid.
4732 * Fixed the WHOWAS command in the server. It now actually works
4733 in router environment. Added function into silcd/command_reply.c
4734 silc_server_command_reply_whowas_save.
4736 * Added silc_idlist_purge function to the silcd/idlist.c
4737 to periodically purge the ID Cache.
4739 * Fixed INFO command in the server. It works now in router
4740 environment. Added <server name> argument to the INFO command
4741 reply. Updated the protocol specs.
4743 * Fixed minor bug in silc_idcache_purge to not purge if the
4744 expire value is zero.
4746 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4747 they were buggy because of the WHOWAS information.
4749 * Fixed local command MSG to handle the async resolving of
4750 the remote client properly. It used to fail the first MSG.
4751 Affected file silc/local_command.c.
4753 * Added `data_len' field to SilcIDCache context.
4755 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4757 * Update TODO. Todo in commands in the server.
4759 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4761 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4762 used by routers as broadcast packet to inform other routers
4763 about the changed user mode.
4765 Implemented the notify handling in the server. Affected file is
4766 silcd/packet_receive.c. Added the function
4767 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4769 * Added new generic Channel Payload and deprecated the New Channel
4770 Payload. The New Channel Payload is now the generic Channel
4773 * Added new argument `mode' to the silc_server_send_new_channel
4774 as it is required in the Channel Payload now.
4776 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4777 and created a new and real SilChannelPayload to represent the
4778 new generic Channel Payload. Implemented the encode/decode
4779 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4781 * Added silc_server_get_client_channel_list to return the list
4782 of channels the client has joined for WHOIS command reply.
4783 Affected file silcd/server.[ch].
4785 * Implemented the channel list sending in the WHOIS command reply
4786 in server and in the client.
4788 Implemented the channel list displaying on the user interface
4789 as well. Affected file silc/client_ops.c.
4791 * Added silc_channel_payload_parse_list to parse list of Channel
4792 Payloads. It returns SilcDList list of SilcChannelPayloads.
4793 Client for example can use this function to parse the list of
4794 channels it receives in the WHOIS command reply. The caller
4795 must free the list by calling silc_channel_payload_list_free.
4796 Affected files lib/silccore/silcchannel.[ch].
4798 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4800 * Added one new argument <user mode> to the WHOIS command reply
4801 to return the mode of the user in SILC. Updated the protocol
4804 Implemented it to the server and client.
4806 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4808 * Fixed the mode printing on the user interface on joining.
4809 Affected file silc/client_ops.c.
4811 * Implemented the UMODE command and user modes in general to the
4812 client library and to the user interface.
4814 * Implemented the UMODE command to the server.
4816 * The server now sends UNKNOWN_COMMAND error status if client sends
4817 unknown command. Affected file silcd/command.c.
4819 * All server commands now handle the command identifier the right
4820 way when sending the command reply to the client. The client can
4821 use to identify the command replies with the identifier.
4823 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4825 * Added silc_server_get_client_route to resolve the route to
4826 the client indicated by the client ID. Affected file is
4829 * Added silc_server_relay_packet as general function to relay
4830 packet to arbitrary destination. This deprecates functions
4831 like _send_private_message_key, _relay_notify etc. Affected
4832 file is silcd/packet_send.[ch].
4834 Removed silc_server_send_key_agreement,
4835 silc_server_send_private_message_key and
4836 silc_server_packet_relay_notify functions from the file
4837 silcd/packet_send.[ch].
4841 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4842 server. Affected file silcd/packet_receive.[ch].
4844 * Implemented the KILL command to the client. Implemented the
4845 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4846 Affected files lib/silcclient/command[_reply].c and
4847 lib/silcclient/client_notify.c. Implemented the KILL notify
4848 printing in the user inteface.
4850 * Fixed a lot silc_parse_nick memory leaks from the client
4851 library in the file lib/silcclient/command.c.
4853 * Changed the silc_server_send_notify_on_channels's `sender'
4854 argument from SilcSocketConnection to SilcClientEntry to
4855 check the sender as entry and not as connection object and not
4856 to send to the client provided as argument. The affected file
4857 is silcd/packet_send.[ch].
4859 * The notify packets that are destined directly to the client used
4860 to not to be processed by the server. Now changed that and the
4861 server processes all notify packets. After relaying the packet
4862 to the client the notify packet is processed in the server.
4864 * The silc_server_free_client_data now checks whether there is
4865 pending outgoing traffic for the client and purges the data to
4866 the network before removing the client entry.
4868 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4870 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4871 an client is killed from the SILC Network. Updated the protocol
4874 Added new function silc_server_send_notify_killed to the
4875 silcd/packet_send.[ch].
4877 * Added function silc_server_packet_relay_notify to relay notify
4878 packets that are destined directly to a client. In this case
4879 the server does not process the notify packets but merely relays
4880 it to the client. Affected file silcd/packet_send.[ch].
4882 Added also silc_server_packet_process_relay_notify to check
4883 whereto relay the notify. Affected file is
4884 silcd/packet_receive.[ch].
4886 * Implemented the KILL command to the server.
4890 * Added the backup schema desgined last fall to the protocol
4891 specs for everyone to see. The specification is in the
4892 *-spec-xx.txt draft and the packet type definitions for the
4893 backup routers is in *-pp-xx.txt draft. Thusly, added also
4894 new packet type SILC_PACKET_CELL_ROUTERS.
4896 * A big security problem in the implementation discovered. The
4897 signoff of an client did not cause new channel key generation
4898 which it of course should've done. The channel keys must be
4899 always re-generated when client leaves (or signoffs) the channel.
4900 The silc_server_remove_from_channels funtion now handles
4901 the channel key re-generation.
4903 * Added `sender' argument to the silc_server_send_notify_on_channels
4904 to not to send the client provided as argument. Affected file
4905 silcd/packet_send.[ch].
4907 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4909 * Implemented OPER and SILCOPER commands into the server and
4912 * Added silc_auth_verify and silc_auth_verify_data to verify
4913 the authentication directly from the authentication payload.
4914 It supports verifying both passphrase and public key based
4915 authentication. Affected file lib/silccore/silcauth.[ch].
4917 * Added `hash' field to the SilcIDListData structure. It is the
4918 hash negotiated in the SKE protocol. Affected file is
4921 * Slight redesigning of the SilcAuthPayload handling routines.
4922 Do not send SilcPKCS but SilcPublicKey as argument.
4924 * Implemented the public key authentication support to the
4925 serverconfig. The public key is loaded from the provided path
4926 and saved as authentication data to void * pointer. Thus,
4927 changed the unsigned char *auth_data to void *auth_data;
4929 * Fixed SHUTDOWN command to send the reply before the server
4930 is shutdown. :) Affected file silcd/command.c.
4932 * Fixed fatal bug in CONNECT command. The hostname was invalid
4933 memory and server crashed. Affected file silcd/command.c.
4935 * Fixed fatal bug in CLOSE command. The server_entry became
4936 invalid but was referenced later in the command. Affected file
4939 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4941 * Fixed fatal bug in failure packet handling. Server ignored
4942 the failure and thus crashed when it came.
4946 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4948 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4949 that the command may be executed only once in (about) 2 seconds.
4950 The old SILC_CF_LAG flag is same but allows command bursts up
4951 to five before limiting.
4953 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4954 server code. Various commands now includes the CF_LAG_STRICT
4955 flag to disallow any kind of miss-use of the command.
4957 * Fixed the silc_buffer_unformat to not to allocate any data
4958 if the length of the data is zero. It used to allocate the
4959 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4961 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4963 * Changed the format of AdminConnection configuration section
4964 in the server. Added username of the admin to the format.
4965 Affected files silcd/serverconfig.[ch].
4967 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4968 to return admin configuration data by host, username and/or
4971 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4973 * Implemented WHOWAS command to the server. Added the functions:
4975 silc_server_command_whowas_parse,
4976 silc_server_command_whowas_send_reply,
4977 silc_server_command_whowas_from_client and
4978 silc_server_command_whowas_from_server
4980 * Added <Client ID> argument to the WHOWAS command reply. Updated
4981 the protocol specs accordingly.
4983 * Implemented WHOWAS command and command_reply to the client
4986 Implemented the WHOWAS printing on the user interface.
4988 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4990 * Added new argument to the WHOWAS command reply, the real name.
4991 It is an optional argument. Updated the protocol specs.
4993 * Added SilcIDCacheDestructor callback that is registered when
4994 the SilcIDCache is allocated. The callback is called when
4995 an cache entry in the ID Cache expires, or is purged from the
4996 cache. Added into lib/silccore/idcache.[ch].
4998 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4999 to destruct the client entries when the cache entry expires.
5000 Other ID Cache's in server and in the client library ignores
5003 * If the ID Cache entry's `expire' field is zero then the entry
5004 never expires. Added boolean `expire' argument to the
5005 silc_idcache_add function in the lib/silccore/idcache.[ch].
5006 If it is TRUE the default expiry value is used.
5008 * Added silc_server_free_client_data_timeout that is registered
5009 when client disconnects. By default for 5 minutes we preserve
5010 the client entry for history - for WHOWAS command.
5012 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5014 * Added support to the server to enforce that commands are not
5015 executed more than once in 2 seconds. If server receives
5016 commands from client more frequently, timeout is registered
5017 to process the commands. Affected file silcd/command.c.
5018 Added new function silc_server_command_process_timeout.
5020 * Changed NICK_NOTIFY handling in client library to check that
5021 if the client's nickname was changed, so there is no need to
5022 resolve anything from the server.
5024 * Removed error printing from the WHOIS and IDENTIFY commands.
5025 If error occurs then it is ignored silently in the client library.
5026 The application, however, may map the received error to
5027 human readable error string. The application currently maps
5028 the NO_SUCH_NICKNAME error to string.
5030 * Made the command status message public to the application. Moved
5031 them from lib/silcclient/command_reply.c to
5032 lib/silcclient/command_reply.h. The application can map the
5033 received command status to the string with the
5034 silc_client_command_status_message function.
5036 * Added check to the server to check that client's ID is same
5037 as the Source ID in the packet the client sent. They must
5040 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5042 * Added dist-bzip hook to the Makefile.am to make bzip2
5043 compressed distributions.
5045 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5047 * Server now enforces the maximum length for the nickname and
5048 the channel as protocol specification dictates. 128 bytes for
5049 nickname and 256 bytes for channel name.
5051 * Moved the WHOIS printing to the application. The client libary
5052 does not print out the WHOIS information anymore, the application
5053 must do it. Renamed silc_client_command_reply_whois_print to
5054 the silc_client_command_reply_whois_save.
5056 The client's idle time is also sent to the application now, and
5057 the idle is shown on screen.
5059 * Added silc_client_command_reply_identify_save to save the
5060 received IDENTIFY entries.
5062 * Do not check for channel private keys in message sending and
5063 reception if the channel does not have the PRIVKEY mode set.
5064 Affected file lib/silclient/client_channel.c.
5066 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5068 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5069 just surfaced after chaning the JOIN procedure.
5071 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5073 * Added silc_client_get_clients_by_list to get client entries
5074 from Client ID list, that is returned for example by JOIN
5075 and USERS command replies. The application should use this
5076 function for example when JOIN command reply is received to
5077 resolve the clients already on the channel (library does not
5078 do that anymore as USERS command reply is not used in the JOIN
5079 procedure anymore). Affected files lib/silcclient/silcapi.h and
5080 lib/silcclient/idlist.c.
5082 * JOIN command reply and USERS command reply returns now SilcBuffer
5083 pointers instead of unsigned char pointers when returning
5084 the client list and mode list.
5086 * Added <Client ID> argument to the JOIN command reply, mainly
5087 for the server to identify for which client the command was
5088 originally sent. Updated protocol specs accordingly.
5090 * Added SilcDlist private_key pointer to the SilcChannelEntry
5091 in the client to support the channel private keys. Affected
5092 file is lib/silcclient/idlist.h.
5094 * Added SilcChannelPrivateKey argument to the function
5095 silc_client_send_channel_message so that application can choose
5096 to use specific private ke if it wants to. If it is not provided,
5097 the normal channel key is used, unless private keys are set.
5098 In this case the first (key that was added first) is used
5099 as the encryption key.
5101 * Implemented the support for channel private key handling.
5102 Implemented the following functions:
5104 silc_client_add_channel_private_key,
5105 silc_client_del_channel_private_keys,
5106 silc_client_del_channel_private_key,
5107 silc_client_list_channel_private_keys and
5108 silc_client_free_channel_private_keys
5110 Affected file lib/silcclient/client_channel.c.
5112 * Added the support for the private keys in the channel message
5113 sending and encryption and in the message reception and
5114 decryption. Affected funtions are
5115 silc_client_send_channel_message and silc_client_channel_message.
5117 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5119 * Added SKE's key verify callback to the client library's
5120 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5122 * Removed the statement that server (or router) must send USERS
5123 command reply when joining to the channel so that the client
5124 knows who are on the channel. Instead, the client list and
5125 client's mode list is now sent in the JOIN command reply to the
5126 client who joined channel. This is better solution.
5128 * Added function silc_server_get_users_on_channel and function
5129 silc_server_save_users_on_channel to the silcd/server.[ch].
5131 * Removed function silc_server_command_send_users from the
5134 * Do not show topic on the client library anymore. The topic is
5135 sent in the command reply notify to the application and the
5136 application must show the topic now.
5138 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5140 * Added client searching by nickname hash into the IDENTIFY and
5141 WHOIS commands in the server as they were clearly missing from
5142 them. Affected file is silcd/command.c.
5144 * Fixed a bug in private message receiving in the client library.
5145 The remote ID was freed and it wasn't supposed, now it is
5148 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5150 * Minor fix to the channel payload; allocate the data area, as it
5151 needs to be of specific length.
5153 * If the key agreement port is zero then the operating
5154 system will define the bound port. Affected files are
5155 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5157 * Added new function silc_channel_payload_decrypt into the file
5158 lib/silccore/silcchannel.[ch].
5160 * Moved the channel message etc, check from silc_packet_decrypt
5161 to applications. The library calls now a generic
5162 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5163 when the packet is either normal or special. This was done to
5164 allow more wide range of checking that was not allowed when
5165 the code was in library. Now applications can do virtually any
5166 checks to the packet and return to the library the decision how
5167 the packet should be processed. Affected files are
5168 lib/silccore/silcpacket.[ch].
5170 Added silc_server_packet_decrypt_check to the server and
5171 silc_client_packet_decrypt_check to the client library.
5173 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5174 to send with specified source and destination information.
5176 * Channel message delivery between routers was broken after the
5177 channel key distribution was fixed earlier. The channel key
5178 was used be to distributed to other routers as well which is not
5179 allowed by the protocol. Now this is fixed and channel keys
5180 really are cell specific and the channel message delivery between
5181 routers comply with the protocol specification.
5183 * Fixed various commands in server to check also the global list
5184 for the channel entry and not just the local list. The affected
5185 file silcd/command.c.
5187 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Added assert()s to buffer formatting and unformatting routines
5190 to assert (if --enable-debug) when error occurs. Affected
5191 file: lib/silcutil/silcbuffmt.c.
5193 * Changed to auto-reconnect to check whether the remote host is
5194 router and register the re-connect timeout if it is. It used
5195 to check that whether we are normal server, but router must do
5196 auto-reconnect with another router as well. Affected file
5199 * Removed the [<key len>] option from CMODE command as the cipher
5200 name decides the key length, nowadays. See the defined ciphers
5201 from the protocol specification.
5203 * Added [<hmac>] option to the CMODE command to define the HMAC
5204 for the channel. Added SILC_CMODE_HMAC channel mode.
5206 * Added [<hmac>] option for the JOIN command so that user can
5207 select which HMAC is used to compute the MACs of the channel
5210 * Added Hmac field to the Channel Message Payload. The integrity
5211 of plaintext channel messages are now protected by computing
5212 MAC of the message and attaching the MAC to the payload. The
5213 MAC is encrypted. Now, it is clear that this causes some
5214 overhead to the size of the packet but rationale for this is that
5215 now the receiver can verify whether the channel message decrypted
5216 correctly and also when private keys are set for the channel the
5217 receiver can decrypt the packet with several keys and check from
5218 the MAC which key decrypted the message correctly.
5220 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5221 lib/silccrypt/silccipher.[ch].
5223 * Added silc_hash_len to return the digest length into the
5224 lib/silcrypt/silchash.[ch].
5226 * Rewrote parts of Silc Channel Payload interface in the
5227 lib/silccore/silcchannel.[ch]. The encode function now also
5228 encrypts the packet and parse function decrypts it.
5230 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5232 * Fixed a minor formatting bug in the SKE's key material processing.
5233 It actually might have processed the keys wrong way resulting
5236 * Redefined the mandatory HMAC algorithms and added new algorithms.
5237 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5238 and hmac-md5 truncated to 96 bits. The mandatory is now
5239 hmac-sha1-96. Rest are optional (including the one that used
5240 to be mandatory). Rationale for this is that the truncated HMAC
5241 length is sufficient from security point of view and can actually
5242 make the attack against the HMAC harder. Also, the truncated
5243 HMAC causes less overhead to the packets. See the RFC2104 for
5246 * Added new [hmac] configuration section. The SKE used to use
5247 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5248 is of course wrong. The official names that must be proposed in
5249 the SKE are the ones defined in the protocol specification
5250 (hmac-sha1-96 for example). The user can configure any hmac
5251 using any hash function configured in the [hash] section. At
5252 least, the mandatory must be configured.
5254 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5256 * Added HMAC list to the SKE proposal list. It has now both
5257 hash algorithm list and HMAC list. This makes the protocol
5258 incompatible with previous versions. The SKE now seems to work
5259 the way it is supposed to work, for the first time actually.
5261 * Defined plain Hash algorithms to the protocol specification.
5264 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5266 * Implemented support for key agreement packets into the server.
5267 Added functions silc_server_key_agreement and
5268 silc_server_send_key_agreement. Other than these functions,
5269 server has nothing to do with this packet.
5271 * Added support for private message key packets into the server.
5272 Added functions silc_server_private_message_key and
5273 silc_server_send_private_message_key.
5277 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5278 called in the protocol's final callback instead in the END
5279 protocol state. This makes a little more sense and in the same
5280 time in client we can use the same protocol routines for normal
5281 key exchange and to key agreement packet handling as well.
5283 * Added to both client's and server's KE protocol context the
5284 SilcSKEKeyMaterial pointer to save the key material. We will
5285 bring the key material to the protocol's final callback by doing
5286 this. The final callback must free the key material.
5288 * Added SKE's packet_send callback into client's KE protocol
5289 context so that the caller can choose what packet sending function
5290 is used. This way we can use different packet sending when
5291 doing normal SKE when doing key agreement packet handling (in
5292 the key agreement packet handling we do not want to encrypt
5295 * Implemented the responder side of the key agreement routines
5296 in the client. The client can now bind to specified port and
5297 accept incoming key negotiation. The key material is passed
5298 to the application after the protocol is over.
5300 * Implemented the processing of incoming Key Agreement packet
5301 in the client. Added function silc_client_key_agreement to
5304 * Implemented the intiator side of the key agreement routines
5305 in the client. The client can now initiate key agreement with
5306 another remote client. The key material is passed to the
5307 application after the protocol is over.
5309 * Created client_keyagr.c to include all the key agreement
5312 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5313 SILC_TASK_CALLBACK except that it is not static.
5315 * Created client_notify.c and moved the Notify packet handling
5316 from the client.[ch] into that file.
5318 * Created client_prvmsg.c and moved all private message and
5319 private message key routines from the client.[ch] into that file.
5321 * Create client_channel.c and moved all channel message and
5322 channel private key routines from the client.[ch] into that file.
5324 * Changed silc_client_get_client_by_id_resolve to resolve with
5325 WHOIS command instead of IDENTIFY command, in the file
5326 lib/silclient/idlist.c.
5328 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5330 * Implemented the SKE's responder side to the Client library.
5332 * When FAILURE is received to the protocol do not trust it
5333 blindly. Register a timeout to wait whether the remote closes
5334 the connection as it should do it, only after that process the
5335 actual failure. This was changed to both client and server.
5337 * Added client_internal.h to include some of the structures
5338 there instead of client.h in lib/silcclient/.
5340 * Added function silc_task_unregister_by_callback to unregister
5341 timeouts by the callback function.
5343 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Some "Incomplete WHOIS info" errors has been appearing on the
5346 log files. Took away the entry->userinfo check from WHOIS
5347 reply sending. The entry->userinfo is now " " if client did not
5348 provide one. I thought this was fixed earlier but something
5349 is wrong still. Let's see if the error still appears.
5351 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5353 * Fixed a minor bug in the login when the channel key is
5354 re-generated in the server. It used to generate the key in
5355 wrong order and thus caused problems in the channel traffic.
5357 * Fixed a minor bug in channel key distsribution after
5358 KICK command. The key was not sent to the router even though
5361 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5363 * Added silc_ske_process_key_material_data as generic routine
5364 to process any key material as the SILC protocol dictates. The
5365 function is used by the actual SKE library but can be used by
5366 applications as well. This relates to the private message keys
5367 and the channel private keys since they must be processed the
5368 same way the normal SILC session keys. The protocol dictates
5369 this. Affected files: lib/silcske/silcske.[ch].
5371 Added also silc_ske_free_key_material to free the
5372 SilcSKEKeyMaterial structure.
5374 * Defined silc_cipher_set_key function to set the key for
5375 cipher without using the object's method function. The affected
5376 files: lib/silccrypt/silccipher.[ch].
5378 * Implemented silc silc_client_add_private_message_key,
5379 silc_client_add_private_message_key_ske,
5380 silc_client_del_private_message_key,
5381 silc_client_list_private_message_keys and
5382 silc_client_free_private_message_keys functions in the
5385 Added functions silc_client_send_private_message_key to send
5386 the Private Message Key payload and silc_client_private_message_key
5387 to handle incoming Private Message Key payload.
5389 * Added Cipher field to the Private Message Key payload to set
5390 the cipher to be used. If ignored, the default cipher defined
5391 in the SILC protocol (aes-256-cbc) is used.
5393 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5395 * Removed lib/silcclient/ops.h file.
5397 Redefined parts of the SILC Client Library API. Created new
5398 file silcapi.h that deprecates the ops.h file and defines the
5399 published Client Library API. Defined also private message key
5400 API and channel private key API into the file.
5402 This is the file that the application must include from the
5403 SILC Client Library. Other files need not be included by
5404 the application anymore.
5406 * Added new key_agreement client operation callback and also
5407 defined the Key Agreement library API for the application.
5409 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5411 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5412 is used by clients to request key negotiation between another
5413 client in the SILC network. If the negotiation is started it
5414 is performed using the SKE protocol. The result of the
5415 negotiation, the secret key material, can be used for example
5416 as private message key.
5418 Implemented the Key Agreement payload into the files
5419 lib/silccore/silauth.[ch].
5421 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5423 * Redefined ciphers for the SILC protocol. Added some new ciphers
5424 and defined the key lengths for the algorithms. Changed the
5425 code accordingly. The default key length is now 256 bits.
5427 * Fixed SKE key distribution function silc_ske_process_key_material
5428 when the key length is more than 128 bits. The default key
5429 length in SILC is now 256 bits.
5431 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5432 to indicate unsupported algorithm.
5434 * Renamed rijndael.c to aes.c and all functions as well.
5436 * Fixed a long standing channel key setting bug in client library.
5437 Weird that it has never surfaced before.
5439 * Fixed bug in channel deletion. If the entire channel is removed
5440 then it must also delete the references of the channel entry
5441 from the client's channel list as the client's channel entry and
5442 the channel's client entry share same memory.
5444 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5446 * Implemented CONNECT and SHUTDOWN commands in the client.
5448 * Implemented CLOSE command to the client.
5450 * Added the function silc_idlist_find_server_by_name into the
5451 files silcd/idlist.[ch].
5453 Added the function silc_idlist_find_server_by_conn into the
5454 files silcd/idlist.[ch].
5456 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5458 * DIE command was renamed to SHUTDOWN. Updated the both code
5461 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5462 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5464 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5467 * Added function silc_server_create_connection function to create
5468 connection to remote router. My server implementation actually
5469 does not allow router to connect to normal server (it expects
5470 that normal server always initiates the connection to the router)
5471 so the CONNECT command is only good for connecting to another
5474 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5476 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5477 or some other client was kicked from the channel.
5479 Implemented the handling of the notify type to both client
5482 Implemented silc_server_send_notify_kicked to send the KICKED
5483 notify. It is used to send it to the server's primary router.
5485 * Implemented the KICK command into server and client.
5487 * Added `query' argument to the silc_idlist_get_client function
5488 to indicate whether to query the client from server or not if
5491 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5492 to indicate that the client is not channel founder.
5496 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5498 * Removed the rng context from SilcPacketContext structure and
5499 changed that the packet routine uses the Global RNG API.
5501 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5503 * Added support for quit message that client can "leave" on the
5504 channel when it quits the SILC. It is ditributed inside the
5505 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5507 Added silc_server_free_client_data that will take the
5508 signoff message as argument.
5510 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5512 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5514 * Updated parts of the protocol specification to keep it up
5517 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5519 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5520 payloads in one packet.
5522 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5523 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5524 use now the new List flag.
5526 * Also deprecated the following packet types: REPLACE_ID,
5527 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5529 * Added list support for Notify packet in server.
5531 * Added silc_server_send_notify_channel_change to send the
5532 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5533 the silc_server_send_replace_id.
5535 * Added silc_server_send_notify_nick_change to send the
5536 NICK_CHANGE notify type. Deprecates the function
5537 silc_server_send_replace_id.
5539 * Added silc_server_send_notify_join to send the JOIN notify type.
5540 Deprecates the function silc_server_send_new_channel_user.
5542 * Added silc_server_send_notify_leave to send LEAVE notify type.
5543 Deprecates the function silc_server_send_remove_channel_user.
5545 * Added silc_server_send_notify_cmode and
5546 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5547 types. Deprecates the silc_server_send_set_mode function.
5549 * Added SERVER_SIGNOFF notify type to indicate that server has
5550 quit. This means that all clients on the channel from that
5551 server will drop. This can be also used when netsplit happens.
5553 Deprecated REMOVE_ID packet type since it is not needed anymore
5556 Added silc_server_send_notify_server_signoff to send the
5557 SERVER_SIGNOFF notify type. Deprecates the function
5558 silc_server_send_remove_id.
5560 Added also silc_server_send_notify_signoff to send the
5561 SIGNOFF notify type.
5563 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5564 SILC protocol from this day on. Changed the protocol
5565 specification as well.
5567 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5568 notify type. It is used between routers to notify about
5569 topic changes on a channel.
5571 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5574 * Partly updated the protocol specification to comply with the
5575 changes now made. It is still though a bit outdated.
5577 * The JOIN notify type now takes one extra argument <Channel ID>.
5578 The packet used to be destined to the channel but now the
5579 JOIN type may be sent as list thus it is impossible to
5580 destine it to any specific channel. By adding this argument
5581 it is again possible.
5583 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Added CREDITS file. The CHANGES and CREDITS file will appear
5586 in the distribution as well.
5588 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5590 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5591 types in the server's silcd/packet_receive.c.
5593 * Implemented CMODE and CUMODE to work in router environment.
5595 * Fixed minor encoding and decoding buglet from the
5596 lib/silccore/silcmode.c.
5598 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5601 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5603 * Changed all SilcConfigServer* and silc_config_server* to
5604 SilcServerConfig* and silc_server_config*, respectively.
5607 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Associated the ID (client or server ID) to the Authentication
5610 Payload to avoid any possibility of forging. Updated the
5611 protocol specification and the code accordingly.
5613 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5615 * The RSA key length is now save to the RsaKey context in the
5616 key generation process in lib/silccrypt/rsa.c. The key length
5617 is now used to figure out the maximum size of the block allowed
5618 to be encrypted/signed.
5620 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5621 is equivalent to the silc_mp_mp2bin but does not allocate any
5624 * Changed silc_mp_mp2bin API to take length argument. If it is
5625 non-zero then the buffer is allocated that large. If zero, then
5626 the size is approximated using silc_mp_sizeinbase, which however
5629 * Created Global RNG API which is global RNG that application can
5630 initialize. After initializing, any routine anywhere in the
5631 code (including library) can use RNG without allocating a new
5632 RNG object. This was done to allow this sort of use of the
5633 RNG in code that has no chance to allocate RNG object. All
5634 applications currently allocate this and many routines in the
5635 library use this. Affected file lib/silccrypt/silcrng.[ch].
5637 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5638 it to use the Global RNG API.
5640 * Defined Authentication Payload into protocol specification that
5641 is used during SILC session to authenticate entities. It is
5642 used for example by client to authenticate itself to the server
5643 to obtain server operator privileges.
5645 Implemented this payload into the lib/silccore/silcauth.[ch].
5646 Implemented also routines for public key based authentication
5647 as the new protocol specification dictates.
5649 Moved definitions of different authentication methods from
5650 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5652 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5653 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5654 silc_pkcs_verify_with_hash functions into the file
5655 lib/silccrypt/silcpkcs.[ch].
5657 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5659 * The client entry's userinfo pointer must be always valid.
5660 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5661 will fail since it requires the userinfo. Now, the userinfo
5662 is allocated as "" if actual userinfo does not exist. Actually,
5663 it must exist and it is totally Ok to drop client connections
5664 that does not announce the userinfo. However, we will make
5665 this workaround for now.
5667 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5668 to return the remote port by socket.
5670 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5672 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5673 SILC_SERVER_PENDING_EXEC and added an new macro
5674 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5675 data or when error occurs while processing the pending command.
5677 Added new argument `destructor' into silc_server_command_pending
5678 and to the SilcServerCommandPending object. This destructor is
5679 now called after calling the pending callback or if error occurs
5680 immediately. If error occurs the actual pending callback won't
5681 be called at all - only the destructor. The destructor may be
5682 NULL if destructor is not needed.
5684 All this applies for client library code as well. Similar
5685 changes were made there as well for the pending commands.
5687 In the client, the application must now allocate the
5688 SilcClientCommandContext with the silc_client_command_alloc
5691 * Added reference counter to the SilcServerCommandContext. Added
5692 function silc_server_command_alloc and silc_server_command_dup
5695 Same type of functions added to the client library for the same
5698 * Removed the cmd_ident from IDListData away since it is now
5699 global for all connections. It is the command identifier used
5700 in command sending and with pending commands. The affected file
5703 * Added reference counter to the SilcSocketConnection objecet to
5704 indicate the usage count of the object. The object won't be
5705 freed untill the reference counter hits zero. Currently only
5706 server uses this, and client ignores it. The client must be
5707 set to use this too later. The affected files are
5708 lib/silccore/silcsockconn.[ch]. Added also the function
5709 silc_socket_dup to increase the reference counter.
5711 This was mainly added because it is possible that the socket
5712 is removed underneath of pending command or other async
5713 operation. Now it won't be free'd and proper DISCONNECTING
5714 flags, etc. can be set to avoid sending data to connection that
5715 is not valid anymore.
5717 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5718 the connection. After that it sets SILC_SET_DISCONNECTED.
5719 It is, however, possible that the socket data is not still freed.
5720 The silc_server_packet_process now checks that data is not
5721 read or written to connection that is DISCONNECTED. The socket
5722 get's freed when the reference counter hits zero.
5724 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5726 * Changed the client operation API: channel_message operation's
5727 `sender' is now the client entry of the sender, not the nickname
5728 and the `channel' is the channel entry, not the channel name.
5730 In the private_message operation the `sender' is now also the
5731 client entry of the sender not the nickname.
5733 Affected file is lib/silcclient/ops.h and all applications
5734 using the client operations.
5736 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Moved the calling of ops->connect() from connect_to_server_final
5739 into receive_new_id functin since that is the point when the
5740 client is actually allowed to send traffic to network. The
5741 affected file is lib/silcclient/client.c.
5743 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5745 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5746 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5747 (if needs broadcasting) instead of broadcasting the packets one
5748 by one which would make a burst in the network traffic.
5750 * Added `broadcast' argument to the functions in silcd/server.[ch]
5751 silc_server_create_new_channel[_with_id] to indicate whether
5752 to send New Channel packet to primary router.
5754 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5756 * Added new function into the silcd/server.[ch] files:
5757 silc_server_create_new_channel_with_id to create new channel with
5758 already existing Channel ID.
5760 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5761 lib/silccore/silcpacket.h. This packet is used t send list of
5762 Set Mode payloads inside one packet. Server uses this to set
5763 the modes for the channels and clients on those channels, that it
5764 announced to the router when it connected to it. The protocol
5765 specification has been updated accordingly.
5767 * The silc_server_new_channel did not handle the packet coming
5768 from normal server as it normally does not send that. However,
5769 when it announces its channels it does send it. Implemented
5770 the support for that.
5772 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5773 into the file lib/silccore/id.h.
5775 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5777 * Fixed memory leaks in the functions silc_idlist_del_client,
5778 silc_idlist_del_channel and silc_idlist_del_server in the file
5779 silcd/idlist.c. All of those leaked like a sieve.
5781 * Fixed some small memory leaks in the client's function
5782 silc_client_notify_by_server.
5784 * Added functions into silcd/server.c: silc_server_announce_clients,
5785 silc_server_announce_channels and silc_server_announce_server.
5786 These functions are used by normal and router server to announce
5787 to its primary router about clients, channels and servers (when
5788 router) that we own. This is done after we've connected to the
5791 These functions effectively implements the following packet types:
5792 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5793 and SILC_PACKET_NEW_ID_LIST.
5795 * Added new functions into the silcd/packet_receive.[ch]:
5796 silc_server_new_id_list, silc_server_new_channel_list and
5797 silc_server_new_channel_user_list to handle the incoming
5798 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5800 * Added support of changing Channel ID in the function
5801 silc_server_replace_id. If the server that announces a channel
5802 to the router already exists in the router (with same name but
5803 with different Channel ID), router is responsible to send
5804 Replace ID packet to the server and force the server to change
5805 the Channel ID to the one router has.
5807 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5808 client that the Channel ID has been changed by the router. The
5809 normal server sends this to the client. Client must start using
5810 the new Channel ID as the channel's ID.
5812 Implemented handling of this new type into lib/silcclient/client.c
5813 into the function silc_client_notify_by_server.
5815 * Added new function silc_idlist_replace_channel_id into the files
5816 silcd/idlist.[ch] to replace the Channel ID.
5818 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5820 * Call silc_server_command_identify_check always when processing
5821 the IDENTIFY command in silcd/command.c
5823 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5825 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5826 send keepalive packets. The packet can be sent by clients,
5827 servers and routers.
5829 Added function silc_socket_set_heartbeat into the file
5830 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5831 If not set, the heartbeat is not performed. The actual
5832 heartbeat is implemented in the low level socket connection
5833 library. However, application is responsible of actually
5836 Added silc_server_send_heartbeat to send the actual heartbeat
5837 packet into silcd/packet_send.[ch]. Server now performs
5838 keepalive with all connections.
5840 * Added silc_task_get_first function into lib/silcutil/silctask.c
5841 to return the timeout task with shortest timeout. There was a bug
5842 in task unregistration that caused problems. TODO has been
5843 updated to include that task system must be rewritten.
5845 * The client library will now resolve the client information when
5846 receiving JOIN notify from server for client that we know but
5847 have incomplete information.
5849 * Rewrote parts of silc_server_remove_from_channels and
5850 silc_server_remove_from_one_channel as they did not remove the
5851 channel in some circumstances even though they should've.
5853 * Encryption problem encountered in server:
5855 The LEAVE command used to send the Channel Key packet to the
5856 router immediately after generating it. However, the code
5857 had earlier sent Remove Channel user packet but not immediately,
5858 ie. it was put to queue. The order of packets in the router
5859 was that Channel Key packet was first and Remove Channel User
5860 packet was second, even though they were encrypted in the
5861 reverse order. For this reason, MAC check failed. Now, this
5862 is fixed by not sending the Channel Key packet immediately but
5863 putting it to queue. However, this is more fundamental problem:
5864 packets that are in queue should actually not be encrypted
5865 because packets that are sent immediately gets encrypted
5866 actually with wrong IV (and thus MAC check fails). So, packets
5867 that are in queue should be encrypted when they are sent to
5868 the wire and not when they put to the queue.
5870 However, the problem is that the current system has not been
5871 designed to work that way. Instead, the packet is encrypted
5872 as soon as possible and left to the queue. The queue is then
5873 just purged into wire. There won't be any fixes for this
5874 any time soon. So, the current semantic for packet sending
5877 o If you send packet to remote host and do not force the send
5878 (the packet will be in queue) then all subsequent packets to the
5879 same remote host must also be put to the queue. Only after the
5880 queue has been purged is it safe again to force the packet
5883 o If you send all packets immediately then it safe to send
5884 any of subsequent packets through the queue, however, after
5885 the first packet is put to queue then any subsequent packets
5886 must also be put to the queue.
5888 Follow these rules and everything works fine.
5890 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5892 * Added new function silc_server_remove_clients_by_server to
5893 remove all client entries from ID list when the server connection
5894 is lost. In this case it is also important to invalidate all
5895 client entires as they hold the invalid server entry. This
5896 fixes fatal bug when server has lost connection and will reconnect
5899 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5901 * Made some sanity checks to silc_server_daemonise like to check
5902 whether the requested user and group actually exists.
5904 * Added sanity check to SKE's silc_ske_responder_finish to check
5905 that the public and private key actually is valid.
5907 * Invalidate the client's nickname when receiving Replace ID
5908 packet and the Client ID is being replaced. This means that the
5909 server will query the nickname if someone needs it (client)
5912 * Sort the ID Cache in client library when the ID Cache data
5913 has changed (needs sorting).
5915 * Do not allow for SILC client to create several connections to
5916 several servers. The client does not support windows right now
5917 and generating multiple connections causes weird behaviour.
5919 Irssi-silc client does support windows and can handle several
5920 connections without problems, see: www.irssi.org and SILC plugin.
5922 * Fixed some places where client was added to the IDList. The
5923 rule of thumb is following (in order to get everything right):
5924 If the client is directly connected local client then the
5925 `connection' argument must be set and `router' argument must be
5926 NULL to silc_idlist_add_client function. If the client is not
5927 directly connected client then the `router' argument must
5928 bet set and the `connection' argument must be NULL to the
5929 silc_idlist_add_client function.
5931 * The funtion silc_server_packet_send_local_channel actually did
5932 not check whether the client was locally connected or not. It
5933 does that now. Fixed a bug related to LEAVE command.
5935 * Fixed Remove Channel User payload parsing bug in server's
5936 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5938 * The server's silc_server_save_channel_key now checks also the
5939 global ID list for the channel as it might not be in the local
5940 list. Fixed a bug related to LEAVE command.
5942 * Is this the end of the [<unknown>] buglet that has been lurking
5943 around for a long time? A little for loop fix in server's
5944 silc_server_command_whois_parse that is used by both IDENTIFY
5945 and WHOIS command. At least, this was a clear bug and a cause
5946 of one type of [<unknown>] buglet.
5948 * WHOIS and IDENTIFY commands call the function
5949 silc_server_command_[whois/identify]_check function even if
5950 we are not router server.
5952 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5954 * Added --with-gmp configuration option. If set the GMP
5955 is always compiled in the SILC source tree. If not set then
5956 it is checked whether the system has the GMP3 installed. If
5957 it has then the GMP won't be compiled (the system's headers
5958 and library is used), if it doesn't have it then the GMP is
5959 compiled in the SILC source tree.
5961 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5963 * Changed RSA private exponent generation to what PKCS #1
5964 suggests. We try to find the smallest possible d by doing
5965 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5966 not security fix but optimization.
5968 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5970 * Added new config entry [Identity] to fork the server and run
5971 it as specific user and group. A patch from Bostik.
5973 * Imported Dotconf configuration library into lib/dotconf.
5974 This will be used to create the SILC configuration files later.
5975 It will appear in the distsribution after this commit.
5977 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5979 * A big code auditing weekend happening. Auditing code for
5980 obvious mistakes, bugs and errors. Also, removing any code
5983 Removed files for being obsolete:
5985 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5986 inline in the file lib/silcutil/silcbuffer.h)
5988 o lib/silcutil/silcbufutil.c (the header has inline versions)
5990 Changed code to fix possible error conditions:
5992 o The buffer formatting routines now check that the destination
5993 buffer really has enough space to add the data. This applies for
5994 both buffer formatting and unformatting
5995 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5996 unformatting was changed to accomodate following rules:
5997 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5998 sent to the function while XXX_*STRING will not allocate or copy
5999 the data into the buffer. Instead it sets the pointer from the
6000 buffer into the pointer sent as argument (XXX_*STRING used to
6001 require that the pointer must be allocated already). This change
6002 makes this whole thing a bit more consistent and more optimized
6003 (note that the data returned in the unformatting with XXX_*STRING
6004 must not be freed now). The routines return now -1 on error.
6006 o Tried to find all code that use buffer_format and buffer_unformat
6007 and added return value checking to prevent formatting and
6008 especially unformatting errors and possible subsequent fatal
6011 o Changed ske->x and ske->KEY to mallocated pointers in
6012 lib/silcske/silcske.h. Fixed possible data and memory leak.
6014 o Added return value checking to all *_parse* functions. Fixed
6015 many memory leaks as well.
6017 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6018 so that buffer overflows would not happen. All code now also
6019 checks the return value as it can fail.
6021 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6023 * Added reconnection support to server if the normal server looses
6024 its connection to the router (for example if router is rebooted).
6025 The server performs normal reconnection strategy implemented
6026 to the server. Affected file silcd/server.c.
6028 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6030 * Added new packet type SILC_PACKET_SET_MODE that is used to
6031 distribute the information about changed modes (for clients,
6032 channels and clients channel modes) to all routers in the
6033 network. Updated the protocol specification accordingly.
6035 Added functions into silcd/packet_send.c and
6036 silcd/packet_receive.c: silc_server_send_set_mode,
6037 silc_server_set_mode.
6039 Added new files silcmode.[ch] into lib/silccore that implements
6040 the encoding and decoding of Set Mode Payload. Added new type
6041 SilcSetModePayload. Moved the definitions of different modes
6042 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6044 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6046 * Oops, a little mistake in server's connection authentication
6047 protocol. The protocol is not ended with FAILURE but with
6048 SUCCESS if the authentication is Ok. :) Affected file is
6051 * Implemented NICK_CHANGE notify handling in server in the file
6052 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6053 the local clients on the channel. After the changing nickname
6054 in router environment snhould work and the [<unknown>] nickname
6055 should appear no more.
6057 The silc_server_replace_id function that receives the Replace ID
6058 payload now sends the NICK_CHANGE notify type also in the file
6059 silcd/packet_receive.c
6061 * Changed WHOIS and IDENTIFY command to support the maximum amount
6062 of arguments defined in protocol specs (3328 arguments). This
6063 fixed a bug that caused problems when there were more than three
6066 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6068 * Added extra parameter, command identifier, to the
6069 silc_client_send_command so that explicit command identifier
6072 Changed that ID list routines uses specific command identifier
6073 when sending WHOIS/IDENTIFY requests to the server so that they
6074 can be identified when the reply comes back.
6076 Affected files lib/silcclient/command.[ch],
6077 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6079 * Added `sender' argument to silc_server_packet_send_to_channel
6080 to indicaet the sender who originally sent the packet to us
6081 that we are now re-sending. Ignored if NULL. Affected file
6082 silcd/packet_send.[ch].
6084 * Added some server statistics support in silcd/server_internal.h
6085 SilcServerStatistics structure and around the server code. Also
6086 send some nice statistics information when client is connecting
6089 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6091 * Fixed channel ID decoding in server's JOIN command reply in
6092 silcd/command_reply.c
6094 * Fixed braodcasting of replace ID payload to not to send it if
6095 we are standalone server in silcd/packet_receive.c.
6097 * Fixed all channel message sending routines to not to send
6098 packets to clients that has router set, since they are routed
6099 separately in the same function earlier. Affects file
6100 silcd/packet_send.c and all channel packet sending functions.
6102 * In USERS reply, res_argv[i] are not allocated, the table
6103 is allocated. Thus changed that free the table, not its
6106 * In server's whois_check and identify_check if the client is
6107 locally connected do not send any WHOIS commands - they are not
6110 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6112 * Fixed some minor bugs in client when sending WHOIS command. The
6113 arguments was in wrong order.
6115 * Removed statis function add_to_channel from server in
6116 silcd/command.c that was previously used with the joining but
6119 * Tested USERS command in router environment successfully with two
6120 routers, two servers and two clients.
6122 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6124 * Reorganized the USERS command and command reply in client library
6125 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6126 When the command is given by user we register a pending command
6127 callback that will reprocess the command after the reply has been
6128 received from the server. When reprocessing the packet we then
6129 display the information. Thus, the USERS information is displayed
6130 now in the command callback instead of in the command reply
6131 callback. The processing of the command is same as previously
6132 when server has sent the command reply in the JOINing process.
6134 * Added to USERS command in silcd/command_reply.c to join the client,
6135 we didn't use to know about, to the channel after we've created
6136 a client entry for it. Also, for clienet we did know already still
6137 check whether it is on the channel or not and add it if not.
6139 * Removed silc_server_command_join_notify as the function and its
6142 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6144 * Changed the client's pending command handling to the same as the
6145 server's pending command handling. It is also now possible to
6146 execute command reply functions from other command reply
6147 function as the function callbacks for commands and command
6148 replies are one and same. The pending commands are not static
6149 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6150 in client connection context. Thus, pending commands are server
6151 connection specific as it is convenient.
6153 Changed the function silc_client_command_pending and
6154 silc_client_command_pending_del and added new function
6155 silc_client_command_pending_check. Removed the
6156 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6159 * Added cmd_ident, current command identifier, to the client
6160 connection context in lib/silcclient/client.h to keep track on
6161 command identifiers used in command sending. Client's command reply
6162 function handling now supports the mandatory command identifiers.
6164 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6165 funtions in client to fully support pending command callbacks.
6167 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6168 as one of the arguments to the application in the command reply
6171 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6172 before first releasing SILC but came back. Now it is removed again
6173 and should come back nomore. The FORWARDED flag was used only
6174 by the JOINing procedure by forwarding the command packet to router.
6175 Now, the JOINing procedure has been changed to more generic (due
6176 to various router environment issues) and FORWARDED is not needed
6177 anymore for anything. The protocol specification is yet to be
6180 Now, removed silc_server_packet_forward from server and the flag
6181 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6183 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6185 * Renamed NAMES command to USERS command. The NAMES was named that
6186 due to historical reasons. Now it is renamed. Also, rewrote
6187 parts of the USERS command. The nickname list is not sent anymore
6188 by the server. Only Client ID and mode lists are sent in the USERS
6189 command. Changed this also to the protocol specification.
6191 The client now resolves the names and stuff after it receives
6192 the USERS list from the server when joining to the channel.
6194 * WHOIS and IDENTIFY commands has been changed to support multiple
6195 Client ID's per command. One can now search for multiple users
6196 in the network by sending only one WHOIS or IDENTIFY command.
6197 Changed the code and the protocol specifications.
6199 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6200 uses silc_server_command_whois_parse to parse the request. */
6202 * If normal server, do not parse the WHOIS and IDENTIFY requests
6203 before sending it to the router. Saves some time.
6205 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6207 * Fixed JOIN command on client library. Wrong number of arguments
6208 used to crash the client.
6210 * Added silc_server_channel_has_global function to check whether
6211 channel has global users or not.
6213 * Added silc_server_channel_has_local function to check whether channel
6214 has locally connected clients on the channel.
6216 * The silc_server_remove_from_one_channel now checks whether the
6217 channel has global users or not after given client was removed from
6218 the channel. It also checks whether the channel has local clients
6219 on the channel anymore. If it does not have then the channel entry
6220 is removed as it is not needed anymore.
6222 * The silc_server_notify now checks on JOIN notify whether the joining
6223 client is one of locally connected or global. If it is global then
6224 the channel has now global users on the channel and that is marked
6225 to the channel entry. Also, it now saves the global client to
6226 global list who is joining and JOINs it to the channel. This is
6227 for normal server, that is.
6229 Changed silc_server_send_notify_on_channel,
6230 silc_server_packet_relay_to_channel and
6231 silc_server_packet_send_to_channel check if we are normal server
6232 and client has router set (ie. global client) do not send the
6233 message to that client, as it is already routed to our router.
6235 * Implemented LEAVE notify type handling in silc_server_notify
6238 * Tested LEAVE command in router environment successfully. Tested
6239 with two routers, two servers and two clients.
6243 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6245 * Implemented SIGNOFF notify type handling in silc_server_notify
6248 * silc_server_remove_id now removes the client entry from all channels
6249 it has joined and thusly sends SIGNOFF notify type.
6251 * Rewrote the NAMES list generation in server by removing two excess
6252 loops. The lists are created now inside one loop.
6254 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6256 * silc_server_remove_channel_user checks now also global list
6257 for channel and client.
6259 * silc_server_new_channel_user checks now both local and global
6260 list for channel and client. Fixed a bug in client id decoding.
6261 Used to decode wrong buffer.
6263 * silc_server_channel_message checks now both local and global
6264 list for channel entry.
6266 * Tested channel joining (hence JOIN) in router environment
6267 successfully. Tested with two routers, two servers and two
6270 * Tested channel message sending in router environment successfully.
6272 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * Added silc_server_save_channel_key into server.[ch] to save the
6275 received channel key in Channel Key payload processing. It is
6276 also used in JOIN command reply handling.
6278 Equivalent function silc_client_save_channel_key added into
6279 client.[ch] into client library.
6281 * Changed JOIN command reply to send information whether the channel
6282 was created or not (is existing already) and the channel key
6283 payload. Changed protocol specs accordingly.
6285 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6286 the request was sent by ID and not by nickname. Crashed on
6289 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6291 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6292 now correctly save the received data.
6294 * silc_server_free_sock_user_data now notifies routers in the
6295 network about entities leaving the network.
6297 At the same time implemented functions silc_server_remove_id
6298 and silc_server_send_remove_id to receive and send REMOVE_ID
6299 packets. The packet is used to notify routers in the network
6300 about leaving entities. The ID removed will become invalid in
6303 * Added function silc_idlist_del_server into server. Removes and
6304 free's server entry from ID list.
6306 * silc_server_private_message function now checks, if we are router,
6307 that the destination ID really is valid ID, naturally.
6309 * In router when NEW_ID packet is received (for new client) the
6310 hash of the Client ID is saved in the ID Cache but the
6311 client->nickname is set to NULL, instead of putting the hash
6314 IDENTIFY command now also checks that client->nickname must be
6315 valid. If it is not if will request the data from the server who
6316 owns the client. Added new function
6317 silc_server_command_identify_check.
6319 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6320 to set the command to already allocated Command Payload.
6322 * Tested private message sending in router environment with two
6323 routers, two servers and two clients. Fixed minor bugs and now
6326 * Fixed segfault from client's NAMES command. Used to crash if
6329 * Forwarded packets must not be routed even if it is not destined
6330 to the receiver. Changed server code comply with this.
6332 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6334 * Added `require_reverse_mapping' boolean value to ServerParams
6335 structure. If TRUE (not default) the server will require that
6336 the connecting host has fully qualified domain name.
6338 If the reverse mapping is not required and hostname could not be
6339 found the IP address is used as hostname.
6341 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6343 * Implemented version string checking to both client and server.
6344 The check is incomplete currently due to the abnormal version
6345 strings used in development version of SILC.
6347 * Changed all command functions in server to use the new
6350 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6352 * Changed char *data to unsigned char *data in ID Cache system to
6353 support binary data as ID Cache data. Changed code to support
6354 binary data in lib/silccore/idcache.c.
6356 * Renamed silc_server_packet_relay_command_reply to
6357 silc_server_command_reply as it is normal packet receiving
6358 function. Rewrote the function to accept command replys for
6359 servers and not only for clients.
6361 * Mark remote router always as registered server if we are connecting
6362 to it. Otherwise, commands sent by the router to us are ignored.
6364 * All ID List find routines now returns the ID Cache Entry pointer
6365 as well if requested.
6367 * WHOIS command works now in router environment, tested with two
6368 routers, two servers and two clients.
6370 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6371 in router environment (as it is almost equivalent to WHOIS) but
6372 hasn't been tested thoroughly. Added new functions:
6374 silc_server_command_identify_parse
6375 silc_server_command_identify_send_reply
6376 silc_server_command_identify_from_client
6377 silc_server_command_identify_from_server
6379 * Disabled route cache adding because adding two different ID's with
6380 same IP replaces the old cache entry thus giving wrong route.
6381 The entry->router->connection is always the fastest route anyway
6382 so route cache may not be needed. Of course, new routes maybe
6383 established after receiving the ID when the entry->router->connection
6384 might not be anymore the most optimal.
6386 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6388 * Add route cache for received ID for fast routing.
6390 * Added silc_server_packet_route to route received packet on router
6391 that is not destined to us.
6393 * Renamed silc_server_get_route to silc_server_route_get.
6395 * Added id_string and id_string_len fields into SilcServer to
6396 include encoded ServerID for fast comparing without excess
6397 encoding of the ID's.
6399 * Cleaned up WHOIS command on server side. Added following static
6402 silc_server_command_whois_parse
6403 silc_server_command_whois_check
6404 silc_server_command_whois_send_reply
6405 silc_server_command_whois_from_client
6406 silc_server_command_whois_from_server
6408 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6409 arguments in command replies. All command functions should be
6410 updated to use this macro.
6412 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6414 * Minor typo fixes on command reply handling on server.
6416 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6418 * Added silc_server_command_add_to_channel internal routine to add
6419 the client to the channel after router has created the channel and
6420 sent command reply to the server.
6422 * Added generic silc_server_send_command to send any command from
6425 * Use static buffer with ID rendering instead of duplicating data.
6427 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6429 * Fixed a channel user mode bug when joining to a channel server gave
6430 everybody channel founder rights, oops.
6432 * We mark ourselves as the router of the incoming server connection
6433 if we are router ourselves. This way we can check in some packet
6434 sending functions whether it is locally connected server. For
6435 incoming router connections we put NULL.
6437 * For router sending packets locally means now always sending the
6438 packet cell wide; to local clients and local servers. For normal
6439 server sending packet locally means sending it to only local
6442 * Fixed the JOIN command to really work in router environment. If the
6443 channel is created it is always created by the router. Router is
6444 also responsible of making the initial joining to the channel,
6445 sending JOIN notify to the sending server and distributing
6446 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6447 does not exist server doesn't do anything else but forward the
6448 command to the router which performs everything.
6450 * Added silc_server_send_channel_key function to send the Channel Key
6453 * Added silc_server_create_channel_key to create new channel key. The
6454 channel key is now re-generated everytime someone joins or leaves
6455 a channel, as protocol dictates. Note: channel->key_len is the
6458 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6460 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6461 packet_receive.[ch] to separate packet sending and receiving
6462 routines. The server.[ch] now includes everything else including
6463 actual packet processing (writing and reading data) and other
6466 Renamed silc_server_private_message_send_internal to
6467 silc_server_send_private_message. The routine is still though
6468 used only to relay private messages as server does not send
6469 private messages itself.
6471 Renamed silc_server_new_channel to silc_server_create_new_channel
6472 and added new function sicl_server_new_channel that handles the
6473 incoming New Channel packet. Added also new sending function
6474 silc_server_send_new_channel to send New Channel Payload.
6476 * Added new function silc_server_notify to process incoming notify
6477 packet to the server/router. Server may then relay the notify
6478 to clients if needed.
6480 * Added new function silc_server_new_channel_user to process incoming
6481 New Channel User packet. Router will redistribute the packet and
6482 send JOIN notify to its local clients and locally connected servers
6483 if needed. Normal server will send JOIN notify to its local client
6484 on same channel when received this packet. Added also corresponding
6485 sending function silc_server_send_new_channel_user to sent the
6488 * Added boolean route argument to send_notif_to_channel and
6489 packet_send_to_channel functions to attempt to route the packet
6490 if it is TRUE and send only locally if it is FALSE.
6492 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6494 * silc_server_replace_id now broadcasts the received replace ID
6495 packet if it is not broadcast packet already. The router must
6496 broadcast to inform other routers about changed ID.
6498 * Added backpointer to server's router into SilcServer context in
6499 silcd/server_internal.h.
6501 * Fixed silc_server_packet_broadcast to send correct broadcast
6504 * The channel key is now distributed to the local client as soon
6505 as it is received from the router (in router environment) so that
6506 no other packet may be sent for the channel until client has
6509 * silc_server_remove_channel_user now broadcasts the received
6510 Remove Channel User packet if it is not broadcast packet already.
6511 The router must broadcast to inform other routers about removed
6514 * Added users field into SilcPacketContext that is a reference count
6515 of the context. One can increase the reference count by calling
6516 silc_packet_context_dup which is now changed to just increase the
6517 reference count instead of duplicating the data. The reference
6518 count is decresed by calling silc_packet_context_free that will
6519 free the data after the reference count hits zero.
6521 For now on the packet context and everything allocated into it
6522 (including the raw packet from network) must be freed by calling
6523 the new silc_packet_context_free function. Added also new function
6524 silc_packet_context_alloc that must be used now to allocate the
6525 context. This also means that if a routine is asynchronous from
6526 silc_[client/server]_packet_parse_type the packet context must
6527 be duplicated by calling silc_packet_context_dup. Otherwise it
6528 gets free'd after silc_[client/server]_packet_parse_type returns.
6529 Also, one must remember that if packet is duplicated then its
6530 reference count must be decresed by calling the free function as
6531 many times as it was duplicated.
6533 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6534 from both client and server.
6536 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6538 * Made joining to a channel working in router environment.
6540 * Cleaned up JOIN command on server side and create function
6541 silc_server_command_join_channel internal routine to make the
6544 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6546 * Changed silc_command_pending list to SilcDList. Also, added
6547 `ident' field to SilcServerCommandPending structure to identify
6548 the reply and to call correct callback.
6550 Added silc_server_command_pending_check function to replace the
6551 corresnponding macro. The silc_command_pending list is not
6554 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6555 to set identifier to previously allocated Command Payload. It
6556 is used to set identifier for command when resending Command
6559 * Added silc_command_payload_encode_payload to encode Command
6560 Payload buffer from SilcCommandPayload structure.
6562 * Added silc_argument_payload_encode_payload to encode Argument
6563 payload buffer from SilcArgumentPayload structure.
6565 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6567 * Changed WHOIS command to support router connection on server side.
6568 The whois request is always sent to router unless the server is
6569 standalone server. After server has received the reply from the
6570 router will it send the reply to the client.
6572 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6573 broadcast received broadcast packet. The function is used only
6574 by router. The broadcast packet is always sent to the router's
6577 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6578 render given ID to printable string, for log files for example.
6580 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6582 * Made basic router to router connections working. At least they
6583 can now connect to each other but nothing really works the way
6584 they are supposed - yet.
6586 * Added new initiator token to RouterConnection configuration
6587 file in silcd/serverconfig.[ch]. It is used to tell whether we
6588 are the initiator to the remote router or whether we'll expect
6589 the other end to connect.
6591 * Moved registering of listener task to silc_server_init, hence
6592 the server starts listenning as soon as it is run, even if it
6593 does not have connections to other routers. Let's see how well
6596 * Changed default connection retry timeouts for more suitable in
6599 * Removed cipher and such arguments from silc_idlist_add_client
6600 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6601 Added new function silc_idlist_add_data to add the keys and stuff
6604 * Added SilcIDListData structure and added it to SilcClientEntry
6605 and SilcServerEntry as their first field in the structure. This
6606 way we can explicitly cast the ID entries to the SilcIDListData
6607 structure and get common data for the entries. In past, we had
6608 to first check what type of connection it is and then cast it to
6609 correct ID entry type. Now, we can directly cast the opaque
6610 pointer to the SilcIDListData (no matter what ID entry it actually
6611 is) and get the data needed.
6613 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6615 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6616 in some circumstances even if threre were timeout tasks, though not
6617 IO tasks, but tasks anyway. Now fixed.
6619 * Defined SilcServerConnection structure to hold connection specific
6620 stuff about directly connected servers and routers. The definition
6621 is currently in silcd/server_internal.h. I thought about having
6622 a bit more important role fro this struct but for now it is used
6623 only when connecting to other server (or router actually).
6625 * Added connecting retry support in server when connecting to
6626 router(s). The retry feature implement exponential backoff
6627 algorithm. Also, added SilcServerParams structure to hold default
6628 parameters for server. For now, it include these retry settings
6629 and are hard coded. After server is moded to be as Silc Server
6630 Library this structure will be more important.
6632 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6634 * Changed client librarys channel->clients table to SilcList and
6635 changed code accordingly.
6637 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6639 * Changed client's channel table to SilcList and changed code
6640 accordingly. Also changed SilcChannelClientEntry to include back-
6641 pointer to the channel so that client entry can use that structure
6642 as list as well and we have fast cross-reference to the channel.
6643 This change dramatically decreased the complexity of channel
6644 handling with client entry and vice versa (removed one extra
6645 loop when searching for channel entry from many functions).
6647 * Changed server->sim from table to SilcDList and changed code
6650 * NAMES command can now be used from user interface. It will show
6651 the user list on the channel, neatly.
6653 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6654 Code now saves realname of the user if it becomes available.
6656 * Renamed configure.in to configure.in.pre and made ./prepare
6657 script to automatically add correct version string to
6658 configure.in which it creates from configure.in.pre.
6660 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6662 * NAMES command reply now shows users mode with the nickname when
6665 * Moved silc_client_ch[u]mode[_char] functions from
6666 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6667 place sucks, they are utility functions and should be in some
6670 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6672 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6675 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6679 * Added TRQ (efficient deque and list library) into lib/trq. This is
6680 a very good list library that is currently used in the SILC. Defined
6681 SilcList API over the library because I didn't like the API very
6682 much. See lib/trq/silclist.h for the API and examples of how to
6683 use the API. Fixed various places in the code to use the new
6684 SilcList API. The SilcList is meant for lists that has a structure
6685 already defined as a list. It is not suitable to add just some
6686 context to the list (in TRQ, the context is the list actually).
6688 So, I defined SilcDList that can be used for the purpose where
6689 predefined list structure does not exit. This can be used as
6690 such list. Now some context just can be added to the SilcDList.
6691 Currently this list is not used in the SILC just yet, though there
6692 are a lot places where this can replace dynamically allocated
6693 tables and I will fix these places, later, to use SilcDList.
6694 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6695 and use TRQ internally).
6697 Also fixed some annoying warning messages that the original TRQ
6698 code generated. Also minor changes to TRQ's Makefile.in.
6700 * Added support for querying by Client ID to both WHOIS and
6701 IDENTIFY commands into server, as required by the protocol.
6703 * Removed method function pointers from SilcBuffer structure. They
6704 weren't used to anything and just increased the context size for
6705 no good reason. This change also made silc_buffer_alloc and
6706 silc_buffer_free functions inline functions.
6708 * Disabled command flooding detection support until it's fixed so
6709 that it accepts commands in but does not execute them more than once
6712 * Added silc_net_localhost(), to return local hostname, into
6713 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6714 that must be initialized before calling silc_client_init.
6716 * Added new function: silc_server_send_notify_on_channels to send
6717 notify messages to all channels client has joined. It is assured
6718 that the message is sent only once per client.
6720 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6721 lib/silcutil/silcutil.[ch] as silc_format function. The new
6722 function is generic and is used by server as well, not only by
6723 the logging routines.
6725 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6726 the provided version string was not acceptable. Added new function:
6727 silc_ske_check_version into lib/silcske/silcske.h. The function
6728 must be implemented by the application (client or server) and it
6729 does not reside in the SKE library. The function checks the version
6730 string remote end sent.
6732 * Added back pointers (to opaque context and to SilcSocketConnection)
6733 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6735 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6736 duplicate packet context structure.
6738 * Changed `notify' client operation to send same arguments as client
6739 receives from server except for ID's. ID's are mapped to correct
6740 ID entry and that is returned. Also, if channel entry is not sent
6741 by server but the notify is for channel the channel entry is sent
6742 to application (otherwise application doesn't know that it is for
6743 channel (library gets it from packet's Destination ID)).
6745 * Added silc_client_remove_from_channels into client library to
6746 remove a client from all channels it has joined to. Used when
6747 received SIGNOFF notify from server. Added also new function
6748 silc_client_replace_from_channels to replace old ID entry with
6749 new ID entry on all channels. Used when received NICK_CHANGE
6752 * Fixed ID Cache list handling in silc_idlist_get_client in
6753 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6754 to get (or query) client by ID.
6756 * Updated TODO list.
6758 * Added connection authentication status message defined by the
6759 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6760 support for these into the code in client and server side.
6762 * Added generic function silc_client_send_command to send any command
6763 with variable argument list. Application should use this function
6764 to send commands if the command functions provided by the library
6765 does not suite for the application's user interface needs.
6767 * Added new `failure' client operation. Application is notified about
6768 received failure packet if client is executing a protocol. In this
6769 case the protocol's execution has failed.
6771 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6772 is required by the protocol.
6774 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6775 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6778 * Added status flag to SilcSKE object to indicate realtime status
6779 of the SKE protocol.
6781 * Application receives now exactly same command reply arguments as
6782 the library receives from server. However, if ID is received the
6783 corresponding ID entry is returned to the application (eg. Client
6784 ID is mapped to correct SilcClientEntry entry and that is returned).
6785 Changed command_reply client operation due to this change.
6787 * Changed all ID's in commands and in command replys as ID Payloads.
6788 Change affected both client and server side codes.
6790 All ID's sent in SILC network (with execption of ID's in SILC
6791 Packet header) are sent in ID Payload to support variable length
6794 * Server now notifies nick changes and notifies all clients on
6795 the channels about the new nickname (about the new Client ID,
6798 * Implemented CMODE command to change channel modes. Supports all
6799 channel modes defined by the protocol specs except ban and invite
6800 lists. (Also, private channel key mode is supported but support for
6801 setting private channel key in client is missing, thus, this mode
6802 has no effect on client side (except that server requires that the
6803 client uses private channel key and normal channel traffic does not
6806 Also, invite mode works per se, but INVITE command does not work
6807 yet correctly, so you can set channel as invite only channel but
6808 inviting clients to the channel does not work (it is yet to be
6809 thought what's the best way to do it).
6811 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6812 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6813 Implemented CUMODE command to change user's mode on the channel.
6814 Supports all modes defined by the protocol specs.
6816 * Added NAMES command reply to return users modes on the channel.
6818 * Removed unnecessary and slow ciphers from lib/silccrypt.
6820 * Set SO_KEEPALIVE option to connection sockets by default.
6822 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6824 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6825 redefined the Notify Payload into protocol specs.
6827 * Added silc_id_payload_parse_id to get ID directly from raw
6830 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6832 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6833 accept searching by Client ID as well.
6835 * Added support for LEAVE and SIGNOFF notify types in client library.
6837 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6838 to parse ID Payload from raw data.
6840 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6842 * Added flags parameter into silc_ske_assemble_security_properties
6843 function in lib/silcske/silcske.[ch].
6845 * Changed notify client operation to fit better for notify messages
6846 sent by server. The notify payload received from server is now
6847 passed to the application (after parsing it to SilcNotifyPayload).
6848 It is application's responsibility to retrieve the arguments
6849 from the payload and show the message the way it wants. The message
6850 sent by server is implementation specific.
6852 * Changed public keys to comply with the protocol specification.
6853 Old public keys are not supported anymore and are not compatible.
6855 * Removed nickname from Channel Payload as the latest draft removed
6856 it. The client must resolve the nickname from the NAMES command
6857 reply received when it joined the channel.
6859 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6861 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6863 * Fixed some errors in protocol specification drafts.
6865 * Created lib/silccore/silcnotify.c to implement Notify Payload
6866 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6867 generic payloads described by protocol specifications. The file
6868 includes implementations for ID Payload and Argument Payload.
6870 * Changed Command Payload implementation to use the new Argument
6871 Payload. Changed command_xxxx_payload to command_payload_xxxx
6872 to comply with SILC coding conventions.
6874 * Added suppport for Argument Payload handling in Notify Payload
6875 implementation as protocol requires it. Added the new support
6876 into server and client lib as well.
6878 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6880 * Added support for multiple nicknames on same channel. [n] is
6881 added locally to the nickname if there are more than one same
6882 nicknames on the channel.
6884 * Server now sends all nicknames that matched WHOIS request.
6885 Client also shows the list received from server.
6887 * Added TOPIC command to client side. User can now set and show
6888 current topic on channel.
6890 * Added MOTD command to client and server. Also, server sends the
6891 motd when client connects to the server.
6893 * Changed version strings to comply ISO 8601.
6895 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6897 * Fixed protocol error handling in client library. It should now
6898 cope even if the SKE fails for some reason.
6900 * Made new protocol specification drafts for submitting to IETF.
6902 * Implemented TOPIC command to server in silcd/command.c.
6904 * Added two new notify types into lib/silccore/silcnotify.h:
6905 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6906 notify nickname change and topic setting/change on a channel.
6908 * API change of command_reply operation in client library. The
6909 application gets now the status type received from server as well.
6911 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6913 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6915 * Cras fixed and optimized the packet handling even further and
6916 it should work now. Minor change to the prototype of function
6917 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6919 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6921 * Added new function into lib/silcutil/silcschedule.[ch]:
6922 silc_schedule_with_fd to select() a specified fd. The function
6923 returns after timeout expires or data arrives or goes. The
6924 function is used by packet routines to wait that all data is
6925 received from network.
6927 * Fixed data reading from network in lib/silccore/silcpacket.c.
6928 The code now assures that all data is read from the fd and then
6929 continues packet processing. This was a bug fix since the code
6930 used to drop some data in some circumstances.
6932 * Added new function into lib/silcclient/client.[ch]:
6933 silc_client_start_key_exchange to start key exchange after
6934 connection has been established to server. The code internally
6935 now uses this funtion but its main purpose was to provide it
6936 for applications that perform their own connecting. After
6937 application has created a connection it merely calls this
6938 function to start the key exchange between client and server.
6939 The library takes care of everything else after that.
6941 Updated also lib/silcclient/README to explain the usage of
6944 * Do not send to application information that connection has
6945 been established. Application gets notified it by connect
6948 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6950 * Applied cras's patch to add silc_schedule_one function. The
6951 function runs scheduler once and returns.
6953 * Fixed the scheduler after cras messed it up. The timeout
6954 handling works now as it's supposed to work.
6956 * Added into lib/silccore/ silcnotify.h to include notify
6957 message types support. Changed silc_server_send_notify*
6958 functions, in server.[ch], to support those new notify types.
6959 Added the support for the notify types into client library,
6960 as well. Added new notify client operation into ops.h in
6963 * Changed silc_server_packet_send_to_channel to send normal
6964 packets instead of just channel message packets. The function
6965 is now used to send the notify packets to channels. It is not
6966 used to send channel message packets anymore, as server never
6969 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6970 va_arg()s as it seems to require it nowadays. I guess, if SILC
6971 is compiled with older va_arg() the new code should work anyway.
6973 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6975 * Splitted core library. Core library (lib/silccore) includes
6976 now only SILC protocol specific core (and common) components.
6977 Created new utility library (lib/silcutil) that includes more
6978 generic purpose stuff. The stuff for util library was taken
6979 from the old core library. This was minor and easy split.
6981 * Created SILC Client Library (lib/silcclient) that includes
6982 implementation of the SILC client without user interface. This
6983 was major move from silc/ directory. The code has been changed
6984 so that it is transparent towards the user interface. The
6985 silc/ directory includes now the same user interface as before
6986 and it uses the new client library. Read lib/silcclient/README.
6987 Basicly, the client library performs everything else related
6988 to SILC except user interface handling. Also, configuration
6989 files are considered to be part of user interface and library
6990 does not handle them.
6992 This change also changed a lot of structures, function naming etc.
6993 Most important change was that SilcClientWindow object was
6994 renamed to SilcClientConnection in the client library. Created
6995 also new file lib/silcclient/ops.h. Also added new files
6996 silc/local_command.[ch] and silc/client_ops.[ch].
6998 All these changes were made to make it easier for user interface
6999 designers to create what ever user interface for the SILC client
7002 It is also expected that the server will be moved to lib
7003 directory as well and SILC Server Library will be created;
7004 sometimes in the future.
7006 * Removed Local commands from lib/silccore/silccommand.h as
7007 they are application specific and new client library does not
7008 handle any of those anymore.
7010 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7011 old client implementation in silc/.
7013 * Added support for callback functions in SILC_LOG_* macros.
7014 Application can now set its own callbacks that will be called
7015 instead of using the default functions that will always print
7016 the debug messages to stderr (or stdout). Also, debugging can
7017 now be disabled by setting silc_debug to FALSE and re-enabled by
7018 setting it to TRUE. Note, that logging will still work even
7019 if debugging is disabled.
7021 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7022 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7023 silc_log_reset_debug_callbacks.
7025 * To enable debugging in silc client one must give now -d
7026 option on command line.
7028 * Changed silc_schedule_init to automatically allocate task queues
7029 if they are not allocated before calling it.
7031 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7033 * Added GMP 3.1 into math library.
7035 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7037 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7038 a channel in SILC network. The packet is used by servers and
7039 routers to notify other routers that user has left a channel.
7040 This little feature was missing until now. Added the feature
7041 to protocol specification as well.
7043 Added functions: silc_server_send_remove_channel_user and
7044 silc_server_remove_channel_user into server.[ch].
7046 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7047 lib/silccore/silcpacket.h. However, they are not implemented
7050 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7052 * Fixed joining to a channel and sending channel messages
7053 between server and router. The channel message sending should
7054 now work inside a cell.
7056 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7058 * Fixed the private message sending between server and router.
7059 The private message sending should now work inside a cell.
7061 * Added silc_server_replace_id into server.[ch] to replace
7062 existing ID in the SILC network.
7064 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7065 and silc_idlist_replace_server_id into idlist.[ch] in server.
7067 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7069 * Fixed the server to server connections. Server can again now
7070 connect to router. Router to router connections probably does
7073 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7075 * Added dynamic protocol registering support. Now protocols can
7076 registered and unregistered on the fly. Patch by cras.
7078 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7080 * Added lib/contrib directory to hold routines that some platforms
7081 don't have but are needed by SILC.
7083 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7084 into lin/contrib to provide getopt() and getopt_long() for
7085 those who don't have it.
7087 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7089 * Added AWAY command to client. When away message is set and
7090 client receives a private message packet the client automatically
7091 replies to the sender with the away message.
7093 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7094 bug seemed to be the cause of recent problems when compiling
7097 * Added version detection support to SKE protocol specification
7098 and added the new changes to the SKE implementation as well.
7099 There were other minor changes in the SKE protocol as well.
7101 Many changes in lib/silcske/silcske.[ch] and in
7102 lib/silcske/payload.[ch].
7104 * Added ^U functionality, clear input line. Patch from cras.
7106 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7108 * Mainly small bugfixes on core library. Fixed some debugging
7109 logging and buffer overflow in silclog.c.
7111 * Updated config.sub and config.guess on the distribution tree.
7113 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7115 * Added command lagging support in server. Client may execute
7116 commands now only once in two seconds.
7118 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7120 * Optimized packet reception. MAC computation and checking is now
7121 also more optimized. A lot previously duplicated code is now
7122 used as generic by both client and server.
7124 * Fixed key pair generation in clientutil.c
7126 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7128 * Added into lib/silccore/silcbufutil.[ch] new function;
7129 silc_buffer_realloc.
7131 * Moved generic packet sending/encryption functions to
7132 lib/silccore/silcpacket.[ch] from client and server. Some
7133 rewriting of the functions.
7135 * Moved all generic packet reception/decryption functions to
7136 lib/silccore/silcpacket.[ch] from client and server. The
7137 packet processing is now much cleaner in both client and server.
7138 These were major changes in both client and server.
7140 * Created many common functions in server to do packet sending.
7141 Previously code were duplicated a lot, this has been removed
7144 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7146 * Rewrote major parts of the ID cache system. Don't know
7147 whether it is better now or not but at least the API is more
7150 * Major rewrite on ID cache stuff on client because of the ID
7151 cache API changes. Added idlist.c to client.
7153 * Also major rewrite on ID cache stuff on server as well.
7154 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7155 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7156 in hand, instead they are all put into the ID cache system now.
7157 All server_idlist_* routines uses ID cache now instead of
7158 traversing its own lists (those lists does not exist anymore).
7159 SilcIDList though still exists. Also, SilcXXXEntry's are
7162 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7164 * Finally made the SKE implementation compliant to the protocol
7165 specification. All mp integers are now binary encoded as
7166 opposed being HEX encoded.
7168 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7171 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7172 functions: silc_[encode/decode]_pem. Also added function
7173 silc_encode_pem_file to PEM encode with newlines ('\n') for
7176 * SILC public keys are now encoded either PEM or binary. Same
7177 option is for private keys as well. By default private keys
7178 are binary encoded and public keys PEM encoded. Silly HEX
7179 encoding were removed.
7181 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7182 function to create fingerprints.
7184 * Fixed a bug in SHA1; does not change the original data anymore.
7186 * Partly implemented INFO command on client and server side.
7187 Fixed CLEAR command. Changes to SERVER command; show current
7188 server(s) when giving command without arguments. Added
7189 VERSION command to client.
7191 * Added check to server that unregistered connections cannot
7192 execute commands (unless it is specificly allowed).
7194 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7196 * Fixed screen refresh.
7198 * Fixed channel joining bug from client. On some circumstances
7199 client tried to join to a channel it had already joined.
7201 * Added public key verification process into client's protocol.c.
7202 The client now verifies the public key from user and saves
7203 it into ~./silc/serverkeys/ directory.
7205 Added into: clientutil.[ch]: silc_client_verify_server_key.
7207 * Changed SKE protocol's silc_ske_initiator_finish function
7208 to accept callback function that verifies the received public
7209 key. Removed old silc_ske_verify_public_key function.
7211 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7213 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7214 silc_pkcs_private_key[_data]_set.
7216 * Made the password and public authentication more cleaner in
7217 server's protocol.c.
7219 * Removed historic and obsolete protocol `channel_auth' from
7220 both client and server.
7222 * Removed wrong way of sending command status messages from
7223 server to client in server's command.c. The old way violated
7224 protocol specification.
7226 Changes to silccore/silccommand.[ch]: removed
7227 silc_command_encode_status_payload -> not needed anymore,
7228 changed silc_command_encode_payload_va to accept extra
7229 argument on variable argument list. The argument type must
7230 now be provided to the function. Also, added new function:
7231 silc_command_encode_reply_payload_va which is same as
7232 normal command_encode_payload_va except command status type
7233 is provided as extra argument.
7235 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7237 * Added ~./silc directory handling. The directory includes the
7238 public and private keys for the client.
7240 Added silc_client_check_silc_dir, silc_client_create_identifier
7241 and silc_client_load_keys.
7243 * Implemented SILC protocol compliant public key. Added public
7244 and private key saving to and loading from files.
7246 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7247 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7248 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7249 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7250 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7252 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7253 silc_pkcs_load_[public/private]_key.
7255 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7257 * Added silc_server_get_route (route.[ch]) to get connection
7258 data for the fastest route for given ID.
7260 * Implemented INVITE command on client and server. The command
7261 were re-defined in the SILC Protocol Specification and the
7262 implementation now complies with the specification.
7264 * Implemented PING command on client and server.
7266 * Implemented NAMES command on client and server. The server side
7267 supports currently only normal server not router server yet.
7268 Some changes to NAMES definition in SILC protocol specification.
7270 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7272 * Implemented LEAVE command on client and server.
7274 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7275 again. This change was made to the protocol as well. Server
7276 should not violate the protocol specification anymore.
7278 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7280 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7281 was tested. SOCKS4 was not but should work anyway.
