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

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

107 * ROBOdoc documented the lib/silcske/silcske.h, and improved
108 the SKE interface a bit.
110 * Fixed padding problem in PKCS#1. The padding was not actually
111 random since the random number generator was used incorrectly.
112 This security bug affects only when encrypting with PKCS#1, and
113 it is not currently used at all in SILC. SILC only use signing
114 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

195 algorithm parts and created new file silcalgs.conf, that
196 is now included from the example_silcd.conf.in.
198 * Optimized the silc_server_connect_to_router_second to take
199 the connection configuration object from the SilcServerConnection
200 object instead of finding it during the connecting phase.
201 Added the configuration object to SilcServerConnection struct.
202 Affected files silcd/server_internal.h, server.c.

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

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

314 * Fixed the channel message payload decryption in the function
315 silc_channel_message_payload_decrypt to not modify the original
316 buffer before it is verified that the message decrypted
317 correctly. Otherwise, next time it is called with correct
318 channel key it won't encrypt since the payload is corrupted.
319 Affected file lib/silccore/silcchannel.c.

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

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

400 * Create the key in JOIN command of the router did not return
401 the channel key, added check for this. Affected file is
404 * Fixed a channel ID update bug in JOIN command reply. Do
405 not directly upgrade the ID but call the function
406 silc_idlist_replace_channel_id if the ID was changed.
407 Affected file silcd/command_reply.c.
409 * Fixed memory leaks from command calling if it would fail.
410 Affected file silcd/command.c.

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

555 the client becoming valid after the server becomes back
556 online. Affected file silcd/server_util.c.
558 * Added `sock_error' field into the SilcSocketConnection
559 context. When error occurs during socket operation (read
560 or write) the error is saved. Added also new function
561 silc_socket_get_error to return human readable socket error
562 message. Affected files are lib/silcutil/silcsockconn.[ch],
563 lib/silcutil/unix/silcunixsockconn.c, and
564 lib/silcutil/win32/silcwin32sockconn.c.
566 * The server now prints the socket error message in the
567 signoff for client. Affected file silcd/server.c.
569 * Fixed the `created' channel information sending from router
570 to server in JOIN command. Checks now whether the channel
571 really was created or not and set it according that.
573 Fixed the JOIN command to use the client entry's current
574 ID during the joining procedure instead of the one it sent
575 in the command (it is checked though), since it can change
576 between the packet processing and command processing, and
577 would just case unnecessary pain in the client end. Affected
578 file silcd/command.c.
580 * Fixed a channel key payload sending to use correct channel
581 ID when the server was forced to change the channel's ID by
582 router. Router sent the key payload with the old Channel ID.
583 Affected file silcd/packet_receive.c.
585 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
587 * Call silc_server_save_channel_key only if the key payload
588 was provided in the JOIN command's command reply. Affected
589 file silcd/command_reply.c.
591 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
593 * Fixed silc_mp_sizeinbase to return the value correctly with
594 MPI. Affected file lib/silcmath/mp_mpi.c.
596 * Fixed the stop_server signal to correctly stop the scheduler
597 and gracefully stop the server when SIGTERM or SIGINT signals
598 are received. Affected file silcd/silcd.c.
600 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
602 * Simple handling of TERM and HUP signals. Also added some log
603 flushing call around. Affected file is
606 * Fixed small bugs in silclog.c. Now buffering output will take
607 effect after 10 seconds since startup: This will ensure that
608 no important startup messages are lost. Also output redirection
609 will preserve original format ([Date] [Type] message).
610 Affected file is lib/silcutil/silclog.c.
612 * Added two options to the config file, in the logging section:
613 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
614 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
616 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
618 * Do not print the warning about log files not being initialized
619 more than once to avoid excess logging. Affected file is
620 lib/silcutil/silclog.c.
622 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
623 the SIM copying in make install in Makefile.am.pre.
625 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
627 * Rewritten silclog APIs. Globally interesting changes follows:
628 silc_log_set_files() changed to silc_log_set_file().
629 silc_log_set_callbacks() changed to silc_log_set_callback().
630 ROBOdoc documented silclog header file.
631 SilcLogCb now returns bool to wether inihibit the default
632 handler or not (to keep the old behaviour return always TRUE).
633 The new APIs should also fix the problem of the
634 silcd_error.log file that was written in the current directory.
637 Log files streams will remain opened after silc_log_set_file()
638 call, means less CPU usage notably on high traffic servers.
639 File streams are now full buffered, and flushed to the disk
640 every 5 minutes, lesses HD activity and CPU usage.
641 Messages can be redirected, allowing admins to configure
642 one single logfile for all server messages.
643 the silc_log_quick global variable to activate fast-logging.
644 Affected files lib/silcutil/silclog.[ch]
646 * Changed some code to conform new silclog APIs. Affected
647 files are doc/example_silcd.conf.in, silcd/server.c
648 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
651 * Fixed a memory leak that could occur in some situations.
652 Affected file silcd/serverconfig.c.
654 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
656 * Added the silc_client_del_client to remove the client from
657 all channels as well. Affected file lib/silcclient/idlist.c.
659 * Fixed the client library to correctly remove the client
660 from all channels when the client entry is being destroyed.
661 Affected file lib/silcclient/client_notify.c, command.c.
663 * Added auto-nicking support to the client library. If the
664 applicatio now sets client->nickname it will be sent to the
665 server after connecting by the library. This way for example
666 SILCNICK (or IRCNICK) environment variables will have effect
667 and always change the nickname automatically to whatever
668 it is wanted. Affected file lib/silcclient/client.[ch].
670 * Renamed silc_server_command_bad_chars to the
671 silc_server_name_bad_chars and moved it to the
672 silcd/server_util.[ch]. Added also new function
673 silc_server_name_modify_bad to return nickname that
674 includes bad characters as new nickname without those
675 bad characters. This check and modify is now used in
676 silc_server_new_client when the username is initially set
677 as nickname, so it must be checked to be valid nickname.
678 Affected file silcd/packet_receive.c.
680 * The nickname length is now taken from the packet for real
681 and not trusted to strlen() since it clearly can return
682 wrong length for nickname including bad characters. This
683 also applies to channel names. Affected file silcd/command.c.
685 * Removed the lib/silcsilm/modules directory. Modules are now
686 compiled into the lib/silcsim. Fixed the copying of the
687 modules to follow symbolic links in Makefile.am.pre.
689 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
691 * Fixed silc_string_regexify list creation. Fixes bugs with
692 BAN and INVITE commands in server. The affected file is
693 lib/silcutil/unix/silcunixutil.c.
695 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
697 * Removed the command destructor entirely from the server's
698 command and command reply routines. It is not needed, and
699 its usage was buggy and caused crashes. Affected files are
700 silcd/command[_reply].[ch].
702 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
704 * Cancel protocol and NULL sock->protocol if timeout
705 occurred during protocol. Affected file silcd/server.c.
707 * Cancel protocol timeouts always before calling the final
708 callback, to assure that after final callback is called
709 no other state will be called for the protocol anymore.
710 Affected file silcd/protocol.c.
712 * Print error log if incoming connection configuration could
713 not be found. Affected file silcd/server.c.
715 * Fixed JOIN command to correctly save the founder mode
716 to the client on normal SILC server, when the channel
717 was created by the router. Affected file silcd/command.c.
719 * Fixed LIST command (hopefully) to send correct reply
720 packets. Affected file silcd/command.c.
722 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
724 * The silc_packet_receive_process now returns FALSE if the
725 read data was invalid packet, and TRUE if it was ok.
727 The server now checks that if unauthenticated connection
728 sends data and its processing fails the server will close
729 the connection since it could be a malicious flooder.
731 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
733 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
735 * Make sure the warning about error opening a log file is
736 printed only once and not everytime it fails (produces
737 too much useless log). Affected file lib/silcutil/silclog.c.
739 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
741 * Made the silc_server_daemonise() function more readable.
742 Affected file silcd/server.c.
744 * Pid file is now optional, the user may comment it out from
745 the config file. Removed define SILC_SERVER_PID_FILE, we
746 don't need a default any longer. Affected file
747 configure.in.pre, lib/Makefile.am.pre.
749 * Make some use of the pid file. The server now dies at startup
750 if it detects a valid pid file on his path. The server would
751 die anyway in this circumstance, because of the bind() failure.
752 Affected file silcd/silcd.c.
754 * No longer compiling lib/dotconf.
756 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
758 * Fixed JOIN command parsing not to crash. Affected file
759 lib/silcclient/command.c.
761 * Fied the NICK_CHANGE notify to add the new client entry
762 even it is resolved. This removes an <[unknown]> nick
763 thingy bug in the client. Affected file is
764 lib/silcclient/client_notify.c.
766 * Do not try to allocate 0 bytes (efence does not like it)
767 in lib/silccore/silccomand.c when encoding payload.
769 * Do not take IRCNICK as nickname in Irssi SILC client since
770 it is not possible to set nickname before hand connecting
771 the server (TODO has an entry about adding auto-nicking
774 * Changed the silc_server_command_pending to check whether
775 there already exists an pending entry with the specified
776 command, command identifier and pending callback. This is
777 to fix IDENTIFY and WHOIS related crashes that may register
778 multiple pending commands with same identifier. Affected
779 file silcd/command.c.
781 * Fixed the server to reconnect to the router even if it
782 was already reconnecting and EOF was received. This to
783 fix a possibility that the server wouldn't ever try to
784 auto-reconnect to the router. Affected file silcd/server.c.
786 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
788 * Fixed the server's password authentication to use the
789 length of the locally saved password, and not the one
790 sent in the packet. Affected file silcd/protocol.c.
792 * Fixed same password authentication problem in the
793 Authentication Payload handling routines in
794 lib/silccore/silcauth.c.
796 * Yet another password authentication problem fixed with
797 channel password handling in silcd/command.c.
799 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
801 * If first character of string in silc_parse_userfqdn is '@'
802 then do not parse it. Affected file is
803 lib/silcutil/silcutil.c.
805 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
807 * Fixed minor bug in IDENTIFY command reply sending, which
808 caused various weird problems during JOIN when it was
809 resolving names for users. Affected file silcd/command.c.
811 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
813 * Fixed the IDENTIFY command reply sending to chech better valid
814 clients. It was possible to send incomplete list of replies.
815 Affected file silcd/command.c.
817 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
819 * Added silc_client_command[s]_[un]register functions now to
820 dynamically register the commands in client library. Removed
821 the static table of commands. This allows the client library
822 to call commands without causing the application to know about
823 what commands library has called.
825 Removed the INFO command reply kludge to detect when the command
826 was called by library. Now library use its own command reply
827 function for INFO command.
829 Added function silc_client_command_call to call a command.
830 Application can use it to call command, not access the structure
833 Now all commands that are sent by the client library (not
834 explicitly sent by application) use own command reply functions.
836 Affected files around lib/silcclient/ and in
837 irssi/src/silc/core/.
839 * Fixed the WHOIS command reply sending to chech better valid
840 clients. It was possible to send incomplete list of replies.
842 Fixed the WHOIS and IDENTIFY to send the request to router
843 if normal server did not do it and did not find any results.
845 Affected file silcd/command.c.
847 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
849 * Moved the internal data from SilcClient context into its
850 own file, not accesible to application. Affected files
851 lib/silcclient/client.h and lib/silcclient/client_internal.h,
852 and other files in client library.
854 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
856 * Added doc/examples installation target in Makefile.am.pre.
859 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
861 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
862 commands the found client entry will be removed from the
863 cache, after notifying application about the error. Affected
864 file lib/silcclient/command_reply.c.
866 * Changed the /MSG to check for exact nickname user gave, and
867 not let `nick' match `nick@host' if it is only one found. Now,
868 user must type the exact nickname (like nick@host2) even if
869 there are no more than one same nicks found. This is to avoid
870 a possibility of sending nickname to wrong nickname since
871 `nick' could match `nick@host'. Affected file is
872 irssi/src/core/silc-servers.c.
874 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
876 * Do not print "you are now server operator" or similar when
877 giving /away command. Affected files are
878 irssi/src/silc/core/client_ops.c, silc-servers.h.
880 * Made the silc_server_command_pending_error_check to send
881 the same command reply payload it received back to the
882 original sender of the command. This way all arguments
883 that was received by the server will be received by the
884 client too. Affected file silcd/command.c.
886 * Added the silc_idcache_add to return the created cache entry
887 to a pointer. Affected file lib/silccore/silcidcache.[ch].
889 * Add global clients to expire if they are not on any channel.
890 This is because normal server will never know if they signoff
891 if they are not on any channel. The cache expiry will take
892 case of these entries. This is done by normal servers only.
893 The affected files are silcd/command_reply.c,
894 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
896 * If server receives invalid ID notification for WHOIS or
897 IDENTIFY and the ID exists in the lists, it is removed.
898 Affected file silcd/command_reply.c.
900 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
901 in client then client entry that it matches is searched and
902 the nickname is printed on the screen for user. Affected
903 file irssi/src/silc/core/client_ops.c.
905 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
907 * Use cache entry expire time in the LIST command reply to
908 purge old entries from the cache after the LIST command
909 reply has been received. This way we don't have non-existent
910 entries in the cache for too long. Affected file is
911 silcd/command_reply.c.
913 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
915 * If we are normal server, and we've not resolved client info
916 in WHOIS or IDENTIFY from router, and it is global client,
917 we'll check whether it is on some channel. If it is not
918 then we cannot be sure about its validity and will resolve it
919 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
920 file silcd/command.c.
922 * Search channel by name (if possible) rather than by ID
923 in IDENTIFY command's command reply. Affected file is
924 silcd/command_reply.c.
926 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
928 * Distribute to the channel passphrase in CMODE_CHANGE notify.
929 Updated specs and implemented it. Affected file silcd/command.c,
930 silcd/packet_send.c and silcd/packet_receive.c.
932 * Implemented the <founder auth> payload handling in the JOIN
933 command. If provided all conditions for channel joining
934 except requirement to provide correct passphrase can be
935 overrided by the channel founder. Updated the protocol specs.
936 Affected file silcd/command.c.
938 Added support for founder auth in JOIN command in client
939 library. Fixed the parsing of the JOIN command now to support
940 all options as they should be. The affected file is
941 lib/silcclient/command.c.
943 * Optimized the WHOIS and IDENTIFY commands to send the request
944 to router only if it includes nicknames or other names. If
945 they include only IDs then check the local cache first before
946 routing. Affected file is silcd/command.c.
948 * Added channels topic announcements. Affected file is
949 silcd/packet_receive.c and silcd/server.c.
951 * Fixed the silc_server_send_notify_topic_set to really destine
952 the packet to channel. Affected file silcd/packet_send.c.
954 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
955 library. Affected file lib/silcclient/client_notify.c.
957 * Added UMODE announcements. Affected file silcd/server.c.
959 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
961 * Memory leak fixes in:
963 lib/silcutil/silcsockconn.c
964 lib/silcske/silcske.c
967 lib/silccrypt/silcpkcs.c
968 lib/silccore/silccommand.c
969 lib/silccore/silcidcache.c
974 * ROBOdoc documented the lib/silcske/groups.h file and a
975 bit changed the interface for better.
977 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
979 * Update the client entry context in the ID cache after
980 nick change. Affected file lib/silcclient/command.c.
981 Fixes the CUMODE command when regaining founder privileges,
982 and a little WHOIS problem.
984 * Fixed silc_net_gethostbyname to correctly call the
985 inet_ntop. Affected file lib/silcutil/silcnet.c.
987 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
989 * Added IPv6 support checking to the configure.in.pre, added
990 also --enable-ipv6 option to override the check. Affected
991 file configure.in.pre.
993 * The silc_thread_create now calls the start function
994 directly if threads support is not compiled in. Removes
995 ugly #ifdef's from generic code. Affected files are
996 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
998 * Added silc_net_gethostby[name/addr]_async to asynchronously
999 resolve. Affected files are lib/silcutil/silcnet.[ch].
1001 * Added support for rendering IPv6 based server, client and
1002 channel IDs. Affected file lib/silcutil/silcutil.c.
1004 * Added support for creating IPv6 based server IDs. Affected
1005 file is silcd/serverid.c.
1007 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1009 * Added silc_net_gethostby[addr/name] into the
1010 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1011 routines. Added silc_net_is_ip[4/6]. Affected file is
1012 lib/silcutil/unix/silcunixnet.c. All routines that take
1013 address as argument now supports both IPv4 and IPv6 addresses.
1015 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1017 * Fixed LIST command reply sending in server. Affected file
1020 * Server now sends the kicker's client ID in the KICK notify
1021 to the kicked client. Affected file silcd/command.c.
1023 * The client library now parses the kickers client ID and
1024 UI displays it. Affected files lib/silcclient/client_notify.c
1025 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1027 * Made all payload parsing function prototypes consistent.
1028 They all take now const unsigned char * and uint32 pair as
1029 the payload data instead of SilcBuffer. Changes all around
1030 the source tree. Other unsigned char* -> const unsigned char*
1031 changes around the tree as well.
1033 * Optimized SFTP client and server packet sending not to
1034 allocate new buffer for each packet but to recycle the
1035 first allocated buffer. Affected files are
1036 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1038 * Optimized the SFTP client to use SilcList instead of
1039 SilcDList for requests, because it is faster. Affected file
1040 is lib/silcsftp/sftp_client.c.
1042 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1043 into lib/silccore/silcid.[ch].
1045 Renamed silcpayload.[ch] into silcargument.[ch].
1047 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1049 * If client entry is deleted with active key agreement
1050 session, abort the session.
1052 The silc_client_abort_key_agreement now calls the completion
1053 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1055 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1058 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1060 * Don't use __restrict in older GCC's. Affected file is
1061 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1063 * silc_net_localhost now attempts to reverse lookup the
1064 IP/hostname. Affected file lib/silcutil/silcnet.c.
1066 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1067 command. It can be used to gain founder privileges at
1068 the same time when joining the channel.
1070 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1071 kicker's client ID as well. Updated protocol specs.
1073 Defined that the server must send SILC_COMMAND_IDENTIFY
1074 command reply with error status to client who sent
1075 private message with invalid client ID.
1077 Updated the protocol specification.
1079 * Added silc_server_send_command_reply to send any
1080 command reply. Affected file silcd/packet_send.[ch].
1082 * Added silc_id_payload_encode_data to encode ID payload
1083 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1085 * The server now send IDENTIFY command reply with error
1086 status if client ID in private message is invalid. Affected
1087 file silcd/packet_receive.c.
1089 * Save the server key file with server's IP address in
1090 the filename instead of hostname. The affected file is
1091 irssi/src/silc/core/client_ops.c.
1093 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1095 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1098 * Added libtool support for compiling shared objects in
1099 lib/silcsim. Affected file configure.in.pre and
1100 lib/silcsim/Makefile.am. Original patch by cras.
1102 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1104 * Pid file configuration, and server's config file fixes
1105 patch by toma. Updated CREDITS file.
1107 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1109 * Fixed silc_client_channel_message to not try to decrypt
1110 the message twice if it resolved the destination client
1111 information. This could cause of dropping one channel
1112 message. Affected file lib/silcclient/client_channel.c.
1114 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1116 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1117 lib/silcclient/client.c. This function is used when the SILC
1118 Client is run under some other scheduler, or event loop or
1119 main loop. On GUI applications, for example this may be
1120 desired to used to run the client under the GUI application's
1121 main loop. Typically the GUI application would register an
1122 idle task that calls this function multiple times in a second
1123 to quickly process the SILC specific data.
1125 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1127 * Fixed silc_server_drop() for dropping the supplementary
1128 groups as well, this could cause a security hole on some
1131 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1133 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1136 * Write PID file after dropping privileges. Added -F option
1137 to run server on foreground. A patch by debolaz.
1138 Affected files silcd/server.c, silcd/silcd.c.
1140 * Fixed MOTD to return the MOTD file server name. Affected
1141 file silcd/command.c.
1143 * Added INFO command reply handling to the Irssi SILC Client.
1144 Affected file irssi/src/silc/core/client_ops.c.
1146 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1148 * Fixed the silc_idcache_list_* routines to really support
1149 the dynamic list. Fixes a crash. Affected file is
1150 lib/silccore/silcidcache.c.
1152 * Fixed the LIST command reply to really call LIST command's
1153 pending callbacks. Affected file silcd/command_reply.c.
1155 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1157 * Update conn->local_entry->nickname after giving NICK
1158 command. Affected file lib/silcclient/command.c.
1160 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1162 * Added the [pid] option to the silcd configuration file
1164 Affected files: serverconfig.[ch] and silcd.c
1166 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1168 * Save fingerprint in WHOIS command reply in server.
1169 Affected file silcd/command_reply.c.
1171 * Fixed NICK commands pending callback registration.
1172 Affected file lib/silcclient/command.c.
1174 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1176 * Use ++server->cmd_ident when sending commands in server,
1177 instead of random number. Affected file silcd/command.c.
1179 * Fixed GETKEY command reply to call actually GETKEY pending
1180 command callbacks. Affected file silcd/command_reply.c.
1182 * A bit stricter check for nicknames. Check for same nickname
1183 in NICK command also. Affected file silcd/command.c.
1185 * Do not call INFO command everytime client ID changes, only
1186 during first connecting. Affected file lib/silcclient/client.c.
1188 * Set the new nickname only after successful command reply for
1189 NICK command is returned by server. Affected file
1190 lib/silcclient/command.c.
1192 * Remove nicknames from nicklist during server_signoff notify.
1193 Should fix /NAMES bit more. The affected file is
1194 irssi/src/silc/core/silc-channels.c.
1196 * Added `fingerprint' field to the SilcIDListData in the
1197 silcd/idlist.h to hold the fingerprint of the client's
1200 Send the fingerprint of the client's public key in WHOIS
1203 Affected files silcd/command.c, and silcd/idlist.[ch].
1205 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1206 create fingerprint from given data.
1208 * Show the fingerprint of the client's public key in WHOIS.
1209 Affected files irssi/src/module-formats.[ch] and
1210 irssi/src/silc/core/client_ops.c.
1212 * Format the multiple same nicknames also during JOIN and
1213 NICK_CHANGE notifys. Affected file is
1214 lib/silcclient/client_notify.c.
1216 * Do not print error on screen for invalid private message
1217 payload since it can come if someone is sending private
1218 messages with wrong key. Affected file
1219 lib/silccore/silcprivate.c.
1221 * Fixed multiple concurrent /PING crash. Affected file
1222 lib/silcclient/command.c.
1224 * Changed the wrong ID encoding. All IP addresses must be
1225 in MSB first order in encoded format. They were encoded
1226 wrong and was in LSB format. Affected files are
1227 silcd/serverid.c, lib/silcutil/silcutil.c.
1229 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1231 * Call the `connect' client operation through the scheduler
1232 in case of error. Affected file lib/silcclient/client.c.
1234 * Call the `failure' client operation even if the error
1235 occurred locally during a protocol. Affected file is
1236 lib/silcclient/protocol.c.
1238 * Added support of sending LIST command to router from normal
1239 server. This way normal server can get list of all channels
1240 in the network too. Fixed the channel list sending in the
1241 server too. Affected files are silcd/command.c, and
1242 silcd/command_reply.[ch].
1244 * Added silc_server_update_channels_by_server and
1245 silc_server_remove_channels_by_server. They are used during
1246 disconnection of primary router and in backup router protocol.
1247 Affected file silcd/server_util.[ch], silcd/server.c and
1248 silcd/server_backup.c.
1250 * Fixed channel adding to global list in IDENTIFY command
1251 reply in server. Affected file silcd/command_reply.c.
1253 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1255 * If the incoming packet type is REKEY or REKEY_DONE process
1256 that packet always synchronously. Fixes yet another MAC
1257 failed error on slow (dialup) connections. Affected file
1258 lib/silcclient/client.c and silcd/server.c.
1260 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1262 * Call check_version SKE callback for initiator too. Affected
1263 file lib/silcske/silcske.c.
1265 * Implemented fix for security hole found in the SKE that was
1266 fixed in the specification few days back; the initiator's
1267 public key is now added to the HASH value computation.
1268 Added backwards support for the old way of doing it too, for
1269 old clients and old servers. Affected file is
1270 lib/silcske/silcske.c.
1272 * Enabled mutual authentication by default in SKE. If initiator
1273 is not providing mutual authentication the responder will
1274 force it. This will provide the proof of posession of the
1275 private key for responder. The affected files are
1276 lib/silcclient/protocol.c and silcd/protocol.c.
1278 * Do not cache anymore the server's public key during SKE.
1279 We do mutual authentication so the proof of posession of
1280 private key is done, and if the server is authenticated in
1281 conn auth protocol with public key we must have the public
1282 key already. Affected file silcd/protocol.c.
1284 * Added new global debug variable: silc_debug_hexdump. If
1285 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1286 file lib/silcutil/silclog.[ch].
1288 * Fixed compilation warning due to char * -> const char *.
1289 Affected files lib/silcutil/silcnet.h, and
1290 lib/silccore/silcauth.[ch].
1292 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1294 * Fixed CMODE command when new channel key was created. If
1295 the creation failed the old key was removed. Next time giving
1296 same command would crash the server since the old key was
1297 freed already. Affected file silcd/command.c.
1299 * Fixed the silc_server_announce_get_channels to not crash
1300 on reconnect. Affected file silcd/server.c.
1302 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1304 * Added silc_log_set_debug_string function to set a regex
1305 string to match for debug output. Only the function names,
1306 or filenames matching the given debug string is actually
1307 printed. This way it is possible to filter out those debug
1308 strings that user is not interested in.
1310 Fixed a bug in silc_string_regexify.
1312 Affected files lib/silcutil/silclog.[ch], and
1313 lib/silcutil/unix/silcunixutil.c.
1315 * Changed the -d options in both server and Irssi SILC client
1316 to take the debug string as argument. Affected files
1317 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1319 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1321 * Added silc_hash_babbleprint to create a Bubble Babble
1322 Encoded fingerprint. The encoding is developed by Antti
1323 Huima (draft-huima-babble-01.txt), and it creates human
1324 readable strings out of binary data. Affected file
1325 lib/silccrypt/silchash.[ch].
1327 * Print the babble print now in addition of fingerprint as well
1328 in Irssi SILC client. Affected files are
1329 irssi/src/fe-common/silc/module-formats.[ch],
1330 irssi/src/fe-common/silc/core/client_ops.c.
1332 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1334 * Fixed a security problem found in SKE. The initiator's
1335 public key too is now added to the HASH hash value creation
1336 which is signed by the responder to create the SIGN value.
1337 This will prevent anyone in the middle to lie to the responder
1338 about the initiator's public key. If this is done now, the
1339 man in the middle will get caught. Updated the protocol
1342 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1344 * Better installation directory handling. Configure module
1345 paths and other paths automatically to example_silc* files
1346 in doc/. A patch by toma.
1348 * Fixed compiler warning from MPI library, and from SILC RNG.
1351 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1352 It can be configured with ./configure. A patch by toma.
1354 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1356 * Find correct make to use in prepare-clean. A patch by
1357 toma. Affected file prepare-clean.
1359 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1361 * Added irssi variables use_auto_addr, auto_bind_ip,
1362 auto_bind_port and auto_public_ip.
1364 * Changed the interface for silc_client_send_key_agreement
1365 in lib/silcclient/silcapi.h
1369 irssi/src/silc/core/silc-core.c
1371 lib/silcclient/silcapi.h
1372 irssi/src/silc/core/silc-channels.c
1373 lib/silcclient/client_keyagr.c
1376 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1378 * Added silc_pkcs_public_key_compare to compare two
1379 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1381 * Check that the client who set the founder mode on the
1382 channel is the same client that is giving the founder
1383 mode to itself. It is done by comparing the saved public
1384 key (it is saved even in the authentication is passphrase).
1385 Affected file silcd/command.c.
1387 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1389 * Do not process packet for disconnected socket connection.
1390 Affected file lib/silccore/silcpacket.c.
1392 * Process the DISCONNECT packet through scheduler in the
1393 client library. Affected file lib/silcclient/client.c.
1395 * Fixed the silc_client_packet_parse to not to increase
1396 the packet sequence number if the conn->sock and the
1397 current socket connection is not same. This can happen
1398 for example during key agreement when the conn includes
1399 multiple socket connections (listeners). Affected file
1400 lib/silcclient/client.c.
1402 * The sender of the file transfer request now provides also
1403 the pointer (listener) for the key exchange protocol. If
1404 the listener cannot be created then it sends empty key
1405 agreement and lets the receiver provide the listener.
1407 Added `local_ip' and `local_port' arguments to the
1408 silc_client_file_send. If they are provided they are used,
1409 if not then it will attempt to find local IP address, if
1410 not found or bind fails then the remote client will provide
1413 Affected files are lib/silcclient/client_ftp.c and
1414 lib/silcclient/silcapi.h.
1416 * Extended the FILE SEND command to support defining the
1417 local IP and port for key exchange listener. They are
1418 optional. Affected file irssi/src/silc/core/silc-servers.c.
1420 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1422 * Defined to WHOIS command reply the sending of fingerprint
1423 of the client's public key (if the proof of posession of the
1424 corresponding private key is verified by the server).
1425 Updated to the protocol specification.
1427 * Added support of receiving the client's public key's
1428 fingerprint in command reply in client library. Affected
1429 file is lib/silcclient/command_reply.c, and
1430 lib/silcclient/idlist.[ch].
1432 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1434 * Do not send over 128 chars long nickname to the server
1435 in NICK command. Affected file lib/silcclient/command.c.
1437 * Do not send over 256 chars long channel names to the server
1438 in JOIN command. Affected file lib/silcclient/command.c.
1440 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1442 * Assure that silc_server_close_connection cannot be called
1443 twice for same socket context. Affected file is
1446 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1448 * Send error message to application if opening file for
1449 writing during file transfer fails. Affected file is
1450 lib/silcclient/client_ftp.c.
1452 Remove all file transfer sessions for a client that we're
1453 removing from ID cache.
1455 Affected file is lib/silcclient/client_ftp.c.
1457 * Fixed silc_net_addr2bin to return correct address. Affected
1458 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1460 * Fixed file transfer session removing on signoff notify.
1461 Affected file irssi/src/silc/core/silc-servers.c.
1463 * Added the SilcClientFileError to be returned in the monitor
1464 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1465 Affected file lib/silcclient/silcapi.h.
1467 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1469 * Fixed a crash in silc_client_ftp_free_sessions and
1470 silc_client_ftp_session_free_client. Affected file
1471 lib/silcclient/client_ftp.c.
1473 * Added `disabled' field in the SilcChannelEntry in the server
1474 to indicate if the server entry is disabled. Affected file
1475 silcd/idlist.h, silcd/command[_reply].c.
1477 * SILC server adds now /var/run/silcd.pid everytime it is
1478 started. Affected file silcd/silcd.c.
1480 * Added silc_server_packet_send_clients to send a packet to
1481 the provided table of client entries. Affected file
1482 silcd/packet_send.[ch].
1484 * Fixed a crash in client resolving in client_prvmsg.c in
1485 client library. Affected file lib/silcclient/client_prvmsg.c.
1487 * Do not actually remove the client directly from ID cache
1488 during SERVER_SIGNOFF, but invalidate it. This way we
1489 preserve the WHOWAS info for the client. Affected file
1490 silcd/server_util.c.
1492 * Fixed SERVER_SIGNOFF notify handling in the server. The
1493 server is now able to process incoming SERVER_SIGNOFF notify
1494 for a server that it doesn't even know about. It will remove
1495 the clients provided in the notify. Affected file
1496 silcd/packet_receive.c.
1498 * Check for partial packet in data queue after every packet that
1499 was found from the queue. Return and wait for more data if
1500 there is partial data in queue. Affected file is
1501 lib/silccore/silcpacket.c.
1503 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1505 * Added SilcClietFileError enum to indicate error in
1506 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1507 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1508 Affected files lib/silcclient/silcapi.h and
1509 lib/silcclient/client_ftp.c.
1511 * Check that newsize in silc_buffer_realloc is larger than
1512 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1514 * Added better monitor of file transfers. It now monitors
1515 key agreement protocol during the file transfer too. Added
1516 error reporting too. Affected files
1517 irssi/src/silc/core/silc-servers.c,
1518 irssi/src/fe-common/silc/module-formats.[ch].
1520 * Wrote a help file for FILE command.
1522 * Added silc_rng_global_get_byte_fast to get not-so-secure
1523 random data as fast as possible. Random data is read from
1524 /dev/urandom if available and from the SILC RNG if not
1525 available. It is used in padding generation. Affected file
1526 lib/silccrypt/silcrng.[ch].
1528 * All packets in client library are now processed synchronously.
1529 Optimized packet processing a lot. Affected file
1530 lib/silcclient/client.c.
1532 * All server connection packets are processing synchronously
1533 now in server, to optimize packet processing. Affected file
1536 * Include files are installed now only in Toolkit distribution
1537 if make install is given. Affected files: all Makefile.am's.
1539 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1541 * Assure that silc_client_notify_by_server_resolve does not
1542 resolve the client information multiple times. If it cannot
1543 be found by the first it cannot be found at all. Affected
1544 file lib/silcclient/client_notify.c.
1546 * Fixed WHOWAS command reply calling. Affected file
1547 lib/silcclient/command_reply.c.
1549 * Removed all references to silc_idlist_get_client from the
1550 Irssi SILC client since that call is internal call used by
1551 the library. The Irssi SILC client will use now client
1552 retrieval functions found in silcapi.h.
1554 * Fixed a bug in resolving nickname info before sending
1555 private message. It used freed memory. Affected file
1556 irssi/src/silc/core/silc-servers.c.
1558 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1560 * Assure my_channels statistics cannot go negative in server.
1561 Affected files silcd/server.c, silcd/server_util.c.
1563 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1573 lib/sftp/sftp_fs_memory.c.
1575 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1577 * Added silc_net_localip to return local host's IP address.
1578 Affected file lib/silcutil/silcnet.[ch].
1580 * If key exchange or rekey protocol is active for a connection
1581 parse all packets syncronously since there might be packets
1582 in packet queue that we are not able to process without first
1583 processing packets before them. Affected file silcd/server,
1584 lib/silcclient/client.c.
1586 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1587 whether library should continue processing the packet.
1588 Affected file lib/silccore/silcpacket.h.
1590 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1591 SilcSFTPMonitorData to SFTP server to monitor various
1592 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

1600 transmission. Affected file lib/silcclient/client_ftp.c,
1601 lib/silccilent/client.[ch].
1603 * Added new local command FILE to the Irssi SILC Client.
1604 It is used to perform the file transfer. It has subcommands
1605 SEND, RECEIVE, SHOW and CLOSE. Affected files
1606 irssi/src/silc/core/client_ops.c,
1607 irssi/src/silc/core/silc-server.[ch].
1609 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1611 * Relay the SILC_PACKET_FTP in the server. Affected files

1616 * Renamed silc_file_read and silc_file_write to functions
1617 silc_file_readfile and silc_file_writefile. Added function
1618 silc_file_open and silc_file_close. Affected files
1619 lib/silcutil/silcutil.[ch].
1621 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1623 * Resolve the client info when received private message or
1624 channel message for a client which nickname we don't know.
1625 Affected files lib/silcclient/client_prvmsg.c and
1626 lib/silcclient/client_channel.c.
1628 * Do not crash in /KEY if client is not connected. Affected

1634 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1635 is incomplete and is being resolved, it won't be resolved
1638 Make sure also that USERS command reply does not resolve
1639 twice information. Affected file is
1640 lib/silcclient/command_reply.c.
1642 Make sure that silc_client_get_clients_by_list does not
1643 resolve twice same information.
1645 * Check for valid client->id in the silc_server_free_client_data.
1646 Affected file silcd/server.c.
1648 * Fixed /GETKEY nick@server not to crash if the server entry
1649 is not found. Affected file lib/silcclient/command.c.
1651 * Fixed the silc_server_check_cmode_rights to check the
1652 requested modes correctly. Affected file silcd/command.c.
1654 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1656 * Better checks for non-printable chars in nick added.
1657 Affected file silcd/command.c.
1659 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1661 * Call the silc_server_udpate_servers_by_server in the
1662 primary router that comes back online in the backup resuming
1663 protocol. Otherwise it routes packets wrong. Affected file
1664 silcd/server_util.[ch], silcd/server_backup.c.
1666 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1668 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1669 lib/silcutil/silcbuffmt.[ch].
1671 * Redefined the SILC packet header to include the padding
1672 length. Affected file lib/silccore/silcpacket.[ch].
1674 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1675 length for maximum padding up to 128 bytes). Affected
1676 file lib/silccore/silcpacket.h.
1678 * Removed all backwards support for old 0.5.x MAC thingies.
1679 The SILC packet header change makes it impossible to be
1680 backwards compatible.
1682 * Send the ENDING packet with timeout in the backup resuming
1683 protocol. This is to assure that all routers has connected
1684 to the primary router. Affected file silcd/server_backup.c.
1686 * Changed the RNG to take the first IV from random data. It
1687 used to take it from zero actually. Changed the RNG also
1688 to use /dev/urandom during session. /dev/random is used
1689 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1691 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1693 * Changed the SILC packet header to have the first two bytes
1694 (the packet length) encrypted. Affected files aroung the
1695 code tree, lib/silccore/silcpacket.[ch]. Removed the
1696 SilcPacketCheckDecrypt callback. It is not needed anymore
1697 since the silc_packet_receive_process will determine now
1698 whether the packet is normal or special.
1700 * Implemented the unidirectional MAC keys. Affected files
1701 lib/silcske/silcske.c, silcd/protocol.c and
1702 lib/silcclient/protocol.c.
1704 * Implemented the packet sequence number to the MAC computation.
1705 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1706 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1707 lib/silcclient/protocol.c.
1709 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1711 * Allow backup router to announce servers. All servers
1712 announced by backup router are added to the global list
1713 automatically. Update hte server's socket to our primary
1714 router also when backup router announces a server.
1715 Affected file silcd/packet_receive.c.
1717 * Do not update the client->router in the function
1718 silc_server_udpate_clients_by_server if the client is on
1719 global list. We might fail to find any specific server
1720 for locally connected clients and local cell clients. They
1721 should still use the `from' and not `to' as client->router.
1722 This fixes backup router resuming protocol. Affected file
1723 silcd/server_util.c.
1725 * Decrease channel statistics count only if the channel
1726 deletion worked. Affected files are silcd/server.c and
1727 silcd/server_util.c.
1729 * Added silc_server_update_servers_by_server to update origin
1730 of all server entries. Used during backup router protocol.
1731 Affected files silcd/server_util.[ch], silcd/server.c. and
1732 silcd/backup_router.c.
1734 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1735 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1736 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1737 lib/silccrypt/silchmac.c.
1739 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1741 * Assure that router cannot reroute the same channel message
1742 to the sender. Affected file silcd/packet_receive.c.
1744 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1746 * Made better checks that the channel message is not sent
1747 to the router it came from. Affected file is
1748 silcd/packet_send.c. Fixed memory leak too.
1750 * Announce informations for incoming router connection, but
1751 only after checking if it is replaced by backup router.
1752 Affected file silcd/packet_receive.c.
1754 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1756 * Fixed the backup resuming protocol to work in multiple
1757 router environment. Affected file silcd/server_backup.c.
1759 * Route packet only to one router in the function
1760 silc_server_packet_send_to_channel. Affected file is
1761 silcd/packet_send.c.
1763 * Fixed silc_server_send_notify_dest to set the broadcast
1764 flag. Fixed the silc_server_send_notify_topic to actually
1765 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1766 Affected file silcd/packet_send.c.
1768 * Changed the SFTP Filesystem interface. Changed the
1769 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1770 the filesystem operation function. The SilcSFTPFilesystem
1771 is now a context that is allocated by all filesystem allocation
1772 functions and it already includes the operations structure
1773 and filesystem specific context. It is given as argument
1774 now to the silc_sftp_server_start. This made the interface
1775 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1776 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1778 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1780 * Changed the backup router adding and getting interfaces
1781 in the server. The router that will be replaced by the
1782 specified backup router is now sent as argument. Affected
1783 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1786 * Added silc_net_addr2bin_ne to return the binary form of
1787 the IP address in network byte order. Affected files
1788 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1790 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1792 * Check for existing server ID in silc_server_new_server
1793 and in silc_server_connect_to_router_final and remove the
1794 old entry if it exists. Affected file silcd/packet_receive.c,
1797 * Send the channel message always to only one router, either
1798 in upstream or downstream. Affected file is
1799 silcd/packet_send.c.
1801 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1803 * Wrote the definition of the backup resuming protocol to the
1804 protocol specification.
1806 * Removed one redundant channel key generation from normal
1807 server during joining procedure. Removed one redundant
1808 channel key sending from server to router during joining
1809 procedure. Affected file silcd/command.c.
1811 * Made minor bugfixes to the backup router resuming protocol.
1812 Affected file silcd/server_backup.c, server.c.
1814 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1816 * Added --disable-asm configuration option. Affected files
1817 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1820 * Implemented the backup resuming protocol that is used to
1821 resume the primary router position in the cell after the
1822 primary router comes back online. Affected files
1823 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1824 and silcd/server_util.[ch].
1826 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1828 * Sleep two (2) seconds after sending QUIT command to server.
1829 Affected file lib/silcclient/command.c.
1831 * Assure that if outgoing data buffer is pending do not force
1832 send any data. Affected file silcd/packet_send.c.
1834 * Assure that if outgoing data buffer is pending do not force
1835 send any data. Affected file lib/silcclient/client.c.
1837 * Implemented the backup router support when the primary router
1838 goes down. The servers and routers can now use the backup
1839 router as new primary router without loosing connectivity.
1841 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1843 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1844 in the server to indicate disabled entry. All data read
1845 from the connection will be ignored and no data is sent
1846 for entry that is disabled. Affected files are
1847 silcd/idlist.h, silcd/server.c.
1849 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1851 * Created SFTP client and server test programs in the
1852 lib/silcsftp/tests directory.
1854 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1856 * Implemented memory filesystem (virtual filesystem) for
1857 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1860 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1862 * Implemented the SFTP (SSH File Transfer Protocol) to the
1863 lib/silcsftp. It includes SFTP client and SFTP server
1866 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1868 * Moved lib/silccore/silcprotocol.[ch] to the
1869 lib/silcutil library.
1871 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1872 take variable argument list pointer as argument. Affected
1873 file lib/silcutil/silcbuffmt.[ch].
1875 * Added silc_buffer_set function that is used to set data
1876 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1877 Affected file lib/silcutil/silcbuffer.h.
1879 * Changed various routines in the core library to use the new
1880 silc_buffer_set instead of allocating new buffer only for
1883 * Added 64-bit value formatting and unformatting support to the
1884 silc_buffer_[un]format routines. Affected file is
1885 lib/silcutil/silcbuffmt.[ch].
1887 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1888 to includes/bitmove.h.
1890 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1892 * Fixed channel user mode saving in client library. Affected
1893 file lib/silcclient/command[_reply].c.
1895 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1897 * Defined the file transfer to the SILC Protocol. Added
1898 new packet type SILC_PACKET_FTP and defined File Transfer
1899 Payload. The mandatory file transfer protocol is SFTP
1900 (SSH File Transfer Protocol). Affected file in addition
1901 of the internet draft is lib/silccore/silcpacket.h.
1903 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1904 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1905 is used as part of backup router protocol when the primary
1906 router of the cell is back online and wishes to resume
1907 the position as primary router.
1909 * Redefined the MAC generation keys in the protocol. The
1910 same key is not used anymore in both direction. Both
1911 direction will now use different keys for sending and
1912 receiving. This fixes a potential security flaw. This
1913 change causes incompatibilities in the protocol.
1915 * Redefined also the MAC computation from the packet.
1916 An packet sequence number is now added to the MAC
1917 computation. This prevents possible replay attacks against
1918 the protocol. This change too causes incompatibilities
1921 Added `sequence' field to the SilcPacketContext to hold
1922 the current sequence number for the packet.
1924 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1926 * Added `created' field to the SilcIDListData in the file
1927 silcd/idlist.h to indicate the time when the entry was
1930 * Added `created' field to the SilcChannelEntry too. Affected
1931 file silcd/idlist.h.
1933 * Added `creation_time' aguments to all the announcement functions
1934 in the server. If it is provided then only the entries that
1935 was created after the provided time frame are actually
1936 announced. Affected file silcd/server.[ch].
1938 * The protocol says that the Channel ID's IP address must be
1939 based on the router's IP address. Added check for this in
1940 the silc_server_new_channel when processing incoming New Channel
1941 Payload. Affected file silcd/packet_receive.c.
1943 * Print out the correct version with --version in SILC client.
1944 Affected file irssi/src/silc/core/silc-core.c.
1946 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1948 * Fixed WHOWAS command to check for completnes of the client
1949 entry always, not just when the command is coming from client.
1950 Affected file silcd/command.c.
1952 * Added new function silc_server_packet_queue_purge to purge the
1953 outgoing data queue to the network. After the function returns
1954 it is guaranteed that the outgoing packet queue is empty.
1955 Affected file silcd/packet_send.[ch].
1957 * Purge the outgoing packet queue in the rekey protocol's final
1958 callback to assure that all rekey packets go to the network
1959 before quitting the protocol. Affected file silcd/server.c.
1961 * Added silc_client_packet_queue_parse as similar function as
1962 in server to the client library. The affected file is
1963 lib/silcclient/client.c.
1965 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1967 * Splitted silcd/server.c and created silcd/server_util.[ch]
1968 for utility functions.
1970 * Added new socket flag SILC_SF_DISABLED to indicate that the
1971 connection is open but nothing can be sent to or received from
1972 the connection. Affected file lib/silcutil/silsockconn.[ch].
1973 The checking for disabled socket is checked in the low level
1974 silc_socket_write and silc_socket_read functions.
1976 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1978 * Allow only nicknames and channel names that fits into the
1979 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1981 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1983 * When processing JOIN command reply in server check that if
1984 the channel exists in our global list we'll move it the local
1985 list. Affected file silcd/command_reply.c.
1987 * Fixed the check whether client is joined on the channel already
1988 in JOIN command. Affected file lib/silcclient/command.c.
1990 * Fixed the JOIN command reply to check whether the channel
1991 already exists. Affected file lib/silcclient/command_reply.c.
1993 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1995 * Added silc_ske_status_string to map the SKE error numbers
1996 to readable strings. The affected files are
1997 lib/silcske/silcske[_status].[ch].
1999 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2001 * Do not show the private channels on the WHOIS channel list
2002 as it is not allowed by the protocol. The affected file is
2005 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2007 * Assure that the packet length digged from the actual packet
2008 is something sensible in the silc_packet_decrypt_rest_special
2009 in lib/silccrypt/silcpacket.c.
2011 * Free and NULL the allocated pointer in silc_hmac_alloc if
2012 the HMAC allocation fails. The affected file is
2013 lib/silccrypt/silchmac.c.
2015 * Print the selected security properties to the log files in
2016 the server. Affected file silcd/protocol.c.
2018 * Add SKE's reference counter even if calling the completion
2019 callback manually. Otherwise it goes negative, although it
2020 does not cause any problems. The affected file is
2021 lib/silcske/silcske.c.
2023 * Remove the client entry with short timeout after giving the
2024 KILL command. Affected file lib/silcclient/command.c.
2026 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2027 case all found clients are already disconnected (WHOWAS would
2028 found them) in the server. Affected file silcd/command.c.
2030 * Update the last_receive (time of last data received) to be
2031 updated only when received private or channel message so that
2032 the idle time showed in WHOIS makes more sense.
2034 * Added boolean field `valid' in to the SilcClientEntry in the
2035 client library to indicate whether the entry is valid or not.
2036 This fixes the nickname change bug on channel when changing
2037 the nickname to be same than the old (like nick to Nick) the
2038 nickname formatter doesn't set the new nick anymore to Nick@host.
2039 Affected file lib/silcclient/idlist.[ch].
2041 * Now actually fixed the nickname changing on disconnection.
2042 Added new function silc_change_nick to the Irssi SILC Client.
2043 Affected file irssi/src/silc/core/client_ops.c,
2044 irssi/src/silc/core/silc-nicklist.[ch].
2046 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2048 * Check that the public key exists in the GETKEY command before
2049 trying to encode it. Affected file silcd/command.c.
2051 * Print some notifications on received public keys with GETKEY
2052 command in the Irssi SILC Client. Affected files are
2053 irssi/src/fe-common/silc/module-formats.[ch],
2054 irssi/src/silc/core/client_ops.c.
2056 * Use IDENTIFY command to resolve the server information in the
2057 GETKEY command instead of INFO command. Affected file
2058 lib/silcclient/command.c.
2060 * All command reply functions in the client library now calls
2061 the pending command reply callbacks even if an error has
2062 occurred. The server has done this a long time and now it was
2063 time to move the client library to this as well. Now all
2064 errors can be delivered back to the pending command reply
2065 callbacks if necessary. Affected files are
2066 lib/silcclient/command[_reply].[ch].
2068 * Change the nickname on disconnection back to the username
2069 because in reconnect the server will enforce it to it anyway.
2070 Affected file irssi/src/silc/core/silc-servers.c.
2072 * Fixed a config file parsing bug in the Irssi SILC client.
2073 Affected file irssi/src/silc/core/clientconfig.c.
2075 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2077 * When printing the channel mode on JOIN, verify that the
2078 channel key and channel's HMAC are valid. Affected file
2079 irssi/src/silc/core/client_ops.c.
2081 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2083 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2084 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2085 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2087 * Removed channel key rekey task deleting from the function
2088 silc_server_save_channel_key. Affected file silcd/server.c.
2089 Added explicit timeout task context instead that is used to
2090 delete the task if we are registering a new task before the
2091 new task has elapsed.
2093 * When channel key rekey occurs the client library now saves
2094 the old channel key for a short period of time (10 seconds) and
2095 is able to use it in case some is still sending channel
2096 messages encrypted with the old key after the rekey. Affected
2097 file lib/silcclient/[idlist.h|client_channel.c].
2099 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2101 * Added check to the silc_server_new_id_real to not accept
2102 new ID if it is the sender's own ID. Affected file is
2103 silcd/packet_receive.c.
2105 * Assure that we do not announce ourself or the one we've
2106 sending our announcements when we're router and are announcing
2107 servers to our primary router. Affected file silcd/server.c.
2109 * Fixed silc_server_command_identify_check_client to assemble
2110 correct WHOIS packet. It send corrupted WHOIS packet and
2111 caused problem with router to router connections. Affected
2112 file silcd/command.c.
2114 Fixed also silc_server_command_whois_check the same way
2115 as for the IDENTIFY command.
2117 * Added new SilcIDListStatus to the server in the SilcIDListData
2118 structure. The status now includes the current status of
2119 the entry (like registered, resolved etc.). Affected file
2120 silcd/idlist.[ch]. Defined a bunch of different status types
2121 as well. This replaced the old boolean registered field as well.
2123 Added resolve_cmd_ident field to the SilcClientEntry structure
2124 too so that if the entry is for example being resolved so
2125 another command may attach to the same pending command reply
2126 without requiring to resolve the same entry again. This concept
2127 should optimize the WHOIS and the IDENTIFY resolving under
2128 heavy load by taking away unnecessary resolving for entries
2129 that are being resolved already.
2131 Added support for adding multiple pending commands for one
2132 command idenfier. Affected file silcd/command[_reply].[ch].
2134 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2135 before deleting the data. Otherwise the hash table will have
2136 freed data in comparison functions. Affected file is
2137 silcd/command_reply.c.
2139 * Fixed silc_idlist_replace_client_id to add the new entry to
2140 the cache with NULL nickname. Otherwise there will be invalid
2141 memory as the nickname after the nickname is freed. Affected
2142 file silcd/packet_receive.c.
2144 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2145 saved into wrong slots because the previous number of entries
2146 was not taken into account. Affected file silcd/idlist.c.
2147 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2149 * If we are router and we receive JOIN notify to a channel that
2150 does not have any users then notified client is marked as the
2151 channel founder, as it is it. The affected file is
2152 silcd/packet_receive.c
2154 * Added to the extended hash table API's table_del_*ext functions
2155 the destructor as argument too, so that the caller can decide
2156 which destructor to use or whether to use destructor at all.
2157 Affected file lib/silcutil/silchashtable.[ch].
2159 * Fixed ID Cache purging. It actually deleted the entries from
2160 the hash table after the data was freed. The hash table ended
2161 up comparing freed memory. The affected file is
2162 lib/silccore/silcidcache.c.
2164 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2166 * Fixed Irssi SILC client's KILL command's HELP syntax.
2168 * The USERS command now resolves the detailed user information
2169 if the userinfo field is missing. Affected file is
2170 lib/silcclient/command_reply.c.
2172 * Do not print error in silc_file_read if the read file does
2173 not exist. Just silently return NULL. Affected file is
2174 lib/silcutil/silcutil.c.
2176 * Fixed the silc_log_output to not wine about NULL filename
2177 and to not create some bogus " " filename. Affected file is
2178 lib/silcutil/silclog.c.
2180 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2182 * Fixed various printing bugs on the user interface in the
2183 Irssi SILC Client. Minor changes that were forgotten from
2186 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2188 * Fixed the configure.in.pre and the compilation and distribution
2189 environment to support the new autoconf 2.52. That version is
2190 now required to compile the CVS trunk.
2192 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2194 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2195 to generally parse user@fqdn format strings. Affected file
2196 lib/silcutil/silcutil.c.
2198 * Added nickname_format and nickname_force_format fields to the
2199 SilcClientParams structure. The first one defines the format
2200 for the nicknames that the library will enforce if the receives
2201 multiple same nicknames. The second one is boolean value and
2202 can be used to force the library to always enforce the format
2203 to the nicknames regardles whether there are multiple nicknames
2204 or not. This configurable formatting was employed to flexibly
2205 support accessing multiple nicknames from the user interface.
2206 The userinterface can now set the nicknames to what ever format
2207 they prefer. Affected file lib/silcclient/silcapi.h.
2209 Added function silc_client_nickname_format to the file
2210 lib/silcclient/idlist.c. It performs the nickname formatting.
2212 Added new field `hostname´ to the SilcClientEntry context.
2213 It holds the hostname of the client. Affected file is
2214 lib/silcclient/idlist.h.
2216 * Irssi SILC Client sets the nicknames in nick@hostn format.
2217 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2218 irssi/src/silc/core/silc-core.c.
2220 The WHOIS printing now also shows both the real nickname and
2221 the formatted nickname so that user knows how to access the
2222 user if there are multiple same nicknames cached. Affected
2223 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2224 printing formatting too to take the hostname now as a separate
2225 argument. The Affected file is
2226 irssi/src/fe-common/silc/modules-formats.[ch].
2228 * Changed the silc_client_get_clients_local to accept the formatted
2229 nickname as argument. It accepts the real nickname too but the
2230 formatted nickname can be used to find the true entry from
2231 multiple entries. Affected file lib/silcclient/silcapi.h and
2232 lib/silcclient/idlist.c.
2234 * Added nickname_format_parse field to the SilcClientParams.
2235 It is a callback function provided by the application to parse
2236 the nickname out of the formatted nickname string. The library
2237 calls it to get the nickname from the formatted string. Since
2238 the application generally knows better the format of the nickname
2239 string it parses it instead of the library, even though library
2240 encodes the formatted string. If the callback function is not
2241 provided then the library will use the string as is. The
2242 affected file is lib/silcclient/silcapi.h.
2244 * All the nickname strings passed to the client library in
2245 commands are now expected to be formatted nickname strings.
2246 If the command does not support the formatted nickname string
2247 it will assume that the sent string is the actual nickname.
2248 Affected file lib/silcclient/command.c.
2250 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2252 * Added public key authentication support to OPER and SILCOPER
2253 commands in the client library. Affected file is
2254 lib/silcclient/command.c.
2256 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2258 * Changed the get_auth_methdod client operation to be asynchronous.
2259 It can be async if the application resolves the authentication
2260 method from the server during the negotiation. Added new
2261 SilcGetAuthMeth completion callback that the application will
2262 call after resolving the authentication method.
2264 Added function silc_client_request_authentication_method that
2265 the application can use to resolve the authentication method
2266 from the server. Added also SilcConnectionAuthRequest callback
2267 that the library will call after the server has replied. The
2268 application can call this function if it does not know the
2269 current authentication method.
2271 Affected files are lib/silcclient/client.c and
2272 lib/silcclient/silcapi.h.
2274 * The Irssi SILC client now automatically resolves the authentication
2275 method incase any configuration information is not present (and
2276 currently there never is). The affected file is
2277 irssi/src/silc/core/client_ops.c.
2279 * Fixed public key authentication from the client library.
2280 Affected file lib/silcclient/protocol.c. Changed also the
2281 protocol specification about the public key authentication in
2282 the connection authentication protocol. The actual data to be
2283 signed is now computed with a hash function before signing.
2285 * Fixed the public key authentication from the server as well.
2286 Affected file silcd/protocol.c.
2288 * Removed the mlock()'s from the memory allocation routines.
2289 Affected file lib/silcutil/silcmemory.c. The ./configure does
2290 not check anymore for the mlock(). Affected file is
2293 * Fixed USERS command in server to allow the execution of the
2294 command for private and secret channels if the client sending
2295 the command is on the channel. Affected file silcd/command.c.
2297 * Fixed silc_client_get_clients_local to return the clients
2298 count correctly. It could return wrong value. Affected file
2299 lib/silcclient/idlist.c.
2301 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2303 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2304 types. The assembler optimizations seemed not to like 64-bit
2305 data types. The assmebler optimizations thus are now enabled
2306 also for BSD systems as opposed to only enable them for Linux.
2308 * Do not check for threads at all on BSD systems. Affected
2309 file configure.in.pre.
2311 * Removed -n and -h options from the Irssi SILC Client since
2312 they are not used in silc.
2314 * Fixed the prime generation to assure that the first digit
2315 of the generated random number is not zero since our conversion
2316 routines does not like number strings that starts with zero
2317 digit. If zero digit is seen the random number is regenerated.
2318 This caused some corrupted RSA keys when the zero first digit
2319 was met. Affected file lib/silcmath/silcprimegen.c.
2321 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2323 * Fixed WIN32 configuration in the ./configure script.
2324 Fixed to include xti.h on environments that has it.
2325 Patches by Carsten Ilchmann and andrew.
2327 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2329 * Changed the silc_id_create_client_id to be collision
2330 resistant. It is now assured that there cannot be created
2331 two same client ID's. I suspect that some weird bugs in
2332 the server were actually caused by duplicate Client IDs.
2333 Affected file silcd/serverid.[ch]. A router receiving
2334 new ID now also assures and informs the sending server
2335 if the ID caused collision.
2337 * Changed the silc_id_create_channel_id to also assure that
2338 there are no collisions.
2340 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2342 * Statement about ignoring the Mutual Authentication flag when
2343 performing rekey with PFS was a bit misleading. It is ignored
2344 if it was set in the initial negotiation, it cannot be even
2345 set in the rekey. Fixed in the ke-auth draft. Started the
2346 new versions of the protocol drafts in the doc/.
2348 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2350 * Fixed a bug in silc_client_command_identify_save when saving
2351 new channel information. The channel name was no duplicated
2352 and caused crash on exit. Affected file is
2353 lib/silcclient/command_reply.c.
2355 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2357 * Fixed the getkey command handling in the server. Send just
2358 empty OK reply to the sender if the key could not be fetched
2359 (but everything else was ok, like the key just was not available).
2360 Changed the public key parameter to optional in the protocol
2361 specs so that empty OK reply can be sent. Affected file
2364 Added a message to Irssi SILC client to tell to user if the
2365 server did not return a public key.
2367 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Fixed a channel key regeneration bug. It registered new
2370 timeout tasks exponentially until all system resources were
2371 used. Affected file silcd/server.c.
2373 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2375 * Added the SILC Document generator to the scripts/silcdoc.
2376 It can be used to generate the Toolkit Reference Manual out
2377 of the source tree. Internally it will also use the RoboDoc
2378 generator now imported in util/robodoc.
2380 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2382 * Added couple of return's in rekey protocol if error orccurred
2383 during the protocol. The execution must be terminated.
2384 Affected file silcd/protocol.c. Also, terminate the protocol
2385 always with timeout.
2387 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2389 * The client's Client ID was created initally from the wrong
2390 nickname (it could have been in format nick@host) in the
2391 silc_server_new_client. Affected file silcd/packet_receive.c
2393 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2395 * Added some SILC_LOG_ERROR's to various error conditions
2396 if client could not be added to ID cache. Affected files
2397 silcd/packet_receive.c and silcd/server.c.
2399 * When client's sock->user_data is freed, NULL also the
2400 client->router and client->connection pointers. Added check
2401 for these pointers being NULL to various places around the
2402 code. Affected file silcd/server.c.
2404 * Added client->data.registered == TRUE checks to various
2405 places around the code to assure that unregistered client's
2406 are not handled when it is not allowed. Affected file
2409 * Added `bool registered' fields to all
2410 silc_idlist_[server|client]_get_* routines to indicate whether
2411 the fetched client needs to be registered or not. Affected
2412 file silcd/idlist.[ch].
2414 * Add your own entry as registered to the ID cache in the
2415 server. Affected file server.c.
2417 * Fixed a bug in silc_server_new_server. The SilcServer was
2418 set as the new server's context instead of SilcServerEntry.
2419 This naturally caused some weird bugs.
2421 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2423 * Do not delete the channel rekey task when adding it
2424 for in silc_server_create_channel_key.
2426 * Changed the silc_server_create_channel_key to return
2427 TRUE or FALSE to indicate the success of the channel key
2430 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2432 * Fixed MSVC++ project files and added missing files to
2433 Makefiles under win32/.
2435 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2437 * Do not add TCP_NODELAY flag if the operating system
2438 does not have it defined. Affected files are
2439 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2441 * Fixed buffer overflow from Irssi SILC Client. Affected
2442 file irssi/src/fe-common/core/themes.c.
2444 * Fixed double free in client library in the file
2445 lib/silcclient/client.c when disconnecting from server.
2447 * Applied double free patch from cras to Irssi SILC client.
2448 Affected files irssi/src/core/[modules/expandos].c
2450 * Fixed the disconnection handling to Irssi SILC Client.
2451 The application must call silc_client_close_connection
2452 in ops->connect client operation in case of failure of
2453 the connection. Affected file is
2454 irssi/src/silc/core/client_ops.c.
2456 * Do not set sock->protocol to NULL in the function
2457 silc_client_close_connection after executing the protocol's
2458 final callback since the sock might not be valid anymore.
2459 Affected file lib/silcclient/client.c.
2461 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2463 * Do not enable SILC_THREADS if the linking with libpthread
2464 did not happen. Affected file configure.in.pre.
2466 * Added notion to protocol specification that server must
2467 verify the sent authentication payload with CMODE when
2468 setting the channel founder key. Implemented it to the
2469 server. Affected file silcd/command.c.
2471 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2473 * Added _EXTRA_DIST SILC distribution variable to the
2474 distributions file. It is used to conditionally add extra
2475 files or directories to the specific distribution. Affected
2476 files ./prepare, Makefile.am.pre and distributions.
2478 Removed the `_' from the start of the distribution names.
2481 * Added README.WIN32 for instructions to compile the Toolkit
2484 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2486 * Fixed a double free in disconnection in the server. Affected
2487 file is silcd/server.c.
2489 * Fixed the lib/silcske/groups.c to work now also with GMP
2490 MP library. The string conversion did not work when using
2491 specific base and the base is indicated in the string as well.
2493 * Created win32/ directory which now includes MSVC++ specific
2494 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2495 It will appear only in the toolkit distribution
2497 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2499 * Changed the key material distribution function in case when
2500 the hash output is too short. The data is now concatenated
2501 a bit differently than it used to. Made the change to the
2502 SKE protocol specification.
2504 * Added better GMP detection to configure.in.pre. A patch
2507 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2509 * Fixed a minor bug in SKE that might cause some problem on
2510 some platforms. Affected file lib/silcske/silcske.c.
2512 * Added the cookie checking for initiator in the SKE. It checks
2513 that the responder returns the sent cookie unmodified. The
2514 affected file is lib/silcske/silcske.c. Added new SKE
2515 error type INVALID_COOKIE that can be sent during the
2516 negotiation. Fixed some memory leaks as well.
2518 * Added the "invalid cookie" error message to Irssi SILC client's
2521 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2523 * Added `task_max' field to the SilcClientParams to indicate
2524 the maximum tasks the scheduler can handle. If set to zero,
2525 default values are used. Affected file lib/silcclient/silcapi.h.
2527 * Fixed memory leaks in silc_client_close_connection. Affected
2528 file lib/silcclient/client.c.
2530 * Added silc_client_del_client_entry to client library to free
2531 all memory of given client entry. Affected file is
2532 lib/silcclient/idlist.[ch].
2534 * Added new functions silc_client_del_channel and
2535 silc_client_del_server to delete channel and server entries.
2536 Affected file lib/silcclient/[silcapi.h/idlist.c].
2538 * Removed silc_client_del_client_by_id from silcapi.h.
2540 * Fixed the INFO command to return the server's own info
2541 correctly when querying by Server ID. Affected file is
2544 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2546 * Removed the non-blocking settings in WIN32 code in the
2547 silc_sock_[read/write] and added SleepEx instead. Affected
2548 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2549 of input data is now checked with FIONREAD and ioctlsocket.
2551 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2553 * Call silc_schedule_task_del_by_context in the
2554 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2555 Affected file lib/silccore/silcprotocol.c.
2557 * Call silc_protocol_cancel for active protocols in the
2558 silc_server_close_connection if the funtion
2559 silc_server_free_sock_user_data has not been called.
2560 Affected file silcd/server.c.
2562 * Generic tasks cannot be deleted using the del_by_fd
2563 task deleting function since generic tasks does not match
2564 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2566 * Added a notion to SILCOPER help file that the SILCOPER works
2567 only on router server, not on normal server.
2569 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2571 * Added for WIN32 support for the new scheduler as well.
2572 Affected file lib/silcutil/win32/silcwin32schedule.c.
2574 * Fixed the SHA1 implementation to work on various platforms.
2576 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2578 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2579 API. It is part of the scheduler now. Everything else is
2580 as previously but some functions has changed their names.
2581 Checkout the lib/silcutil/silcschedule.h for the interface.
2582 Updated all applications to use the new interface. Affected
2583 files are lib/silcutil/silcschedule.[ch].
2585 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2587 * Found a bug in the SKE implementation. The HASH value,
2588 specified by the protocol, was not computed correctly. The
2589 public key of the responder was not added to the computation
2590 even though it is mandatory. Affected file lib/silcske/silcske.c.
2591 This unfortunately causes incompatibilities with older
2592 clients and servers.
2594 * Added WIN32 specific network init and uninit functions:
2595 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2596 the Winsock2. Affected file lib/silcutil/silcnet.h and
2597 lib/silcutil/win32/silcwin32net.c.
2599 * Set the socket always to nonblocking mode on WIN32 after
2600 reading data or writing data. Affected file is
2601 lib/silcutil/win32/silcwin32sockconn.c.
2603 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2605 * Fixed various compilation problems under WIN32. Affected
2606 files lib/silcutil/win32/silcwin32thread.c and
2607 lib/silcutil/win32/silcwin32schedule.c.
2609 * Removed all _internal.h #includes from public header
2610 files. Internal headers must never be included from
2613 Removed also the lib/silcske/payload_internal.h file.
2615 * All include files that may be needed (public and some others
2616 included by the public headers) by application developers are
2617 now copied to the ./includes directory. It does not copy any
2618 internal headers. Affected file Makefile.defines.pre and all
2619 Makefile.am's under lib/ and subdirs.
2621 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2623 * Do not change the ~/.silc directory's permissions automatically.
2624 Affected file irssi/src/silc/core/clientutil.c.
2626 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2628 * Do not cancel the protocol in silc_server_close_connection
2629 it might cause recursion. Now cancelled in the function
2630 silc_server_free_sock_user_data. Affected file silcd/server.c.
2632 * Fixed the silc_server_remove_clients_by_server to regenerate
2633 the channel keys correctly finally. Added also new function
2634 silc_server_remove_clients_channels to actually do it.
2635 Affected file silcd/server.c.
2637 * Fixed the silc_server_new_channel to not crash by giving
2638 wrong router to the new channel. Affected file is
2639 silcd/packet_receive.c.
2641 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2643 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2644 which is given as argument to the silc_client_alloc now.
2645 It can be used to configure the client and set various parameters
2646 that affect the function of the client.
2648 * The USERS command in server did not check whether the channel
2649 is private or secret. Affected file silcd/command.c.
2651 * Added new argument to the USERS command in protocol specification.
2652 The USERS command now can take the channel name as argument
2653 as well. Added support for this in client and server and
2654 updated the protocol specs.
2656 * Completed the GETKEY command in client. It can be now used
2657 to fetch also servers public key not only some clients.
2658 Affected files lib/silcclient/command[_reply].c.
2660 * Added silc_client_get_server to return server entry by the
2661 server name. Affected files lib/silcclient/silcapi.h and
2664 * Redefined the IDENTIFY command in protocol specification to be
2665 more generic. It now can be used to query information about
2666 any entity in the SILC Network, including clients, servers and
2667 channels. The query may be based either the entity's name
2668 or the ID. Added support for this in both client and server.
2670 Affected files silcd/command.c and lib/silcclient/command.c
2671 and command_reply.c.
2673 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2674 the _from_client and _from_server functions. Affected file
2677 * Added silc_client_get_channel_by_id_resolve to the file
2678 lib/silcclient/silcapi.h to resolve channel information by
2679 its ID. Added also silc_client_get_channel_by_id that
2680 does not resolve it from the server.
2682 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2684 * Added SilcServerEntry context into the client library
2685 to represent one server. The INFO command now allocates
2686 these to save the resolved server info. For now on the
2687 client library will also keep information about servers,
2688 connected and resolved with INFO.
2690 The INFO command now allocates the SilcServerEntry context
2691 and saves the server info there. The COMMAND_REPLY in
2692 the INFO now returns the parameters to application in
2693 same order as defined in the protocol specification.
2695 The entries are cached in the client->server_cache.
2697 * The INFO command is now issued after received the Client ID
2698 from the server. Affected file lib/silcclient/client.c.
2700 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2701 to the application as the mode changer might be server.
2702 It is guaranteed that NULL is not returned anymore to the
2703 application. Affected file lib/silcclient/client_notify.c.
2705 The ID Type is now also passed to the application so that
2706 it can check whether the returned entry is SilcClientEntry
2709 Added new function silc_client_get_server_by_id to return
2710 the server entry by ID. Affected files are the
2711 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2713 * Do not create the channel in the Irssi SILC Client when issuing
2714 the JOIN command but when received the sucessful JOIN command
2715 reply. Otherwise the channel might get created even though we
2716 could not join it. The Affected file is
2717 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2719 * Fixed a channel joining bug in router. The router must also
2720 check the channel modes, invite and ban lists etc. when serving
2721 the JOIN command sent by normal server. Affected file is
2722 silcd/command.c. The router now resolves the client's
2723 information from the server who sent the JOIN command if it
2724 does not know it, and processes the JOIN command only after
2727 * Changed the SilcCommandCb to take new argument; void *context2.
2728 Affected file lib/silccore/silccommand.h
2730 The second argument in the command callbacks in the server now
2731 includes the SilcServerCommandReplyContext if the command was
2732 called as pending command callback from the command reply.
2733 Otherwise it is NULL. When called as pending the status of the
2734 command reply will be checked and if it was erronous the
2735 error will be sent to the original sender of the command.
2736 This way the client always receives the error messages even
2737 though the server was actually the one who received the error
2738 when it resent the command to router, for example. Affected
2739 files silcd/command[_reply].[ch].
2741 * Fixed sending WHOWAS command's error message to client if
2742 the requested client could not be found. It was missing.
2745 * Changed the CMODE and CUMODE commands reply arguments in the
2746 protocol specification. The Channel ID is now sent in both
2747 of the commands to identify the channel. Implemented this
2748 new feature to the client and server. Affected files
2749 lib/silcclient/command_reply.c and silcd/command.c.
2751 * Made better checks for invite and ban lists in the JOIN
2752 command in server. Affected file silcd/command.c.
2754 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2756 * The server now performs the incoming host IP/DNS lookup
2757 using the silc_socket_host_lookup and thus does not block
2758 the server anymore. Affected file silcd/server.c.
2760 * Completed the multi-thread support for SILC Scheduler in
2761 the lib/silcutil/silcschedule.c.
2763 * Fixed the configure.in.pre to detect the pthread correctly
2766 * Fixed a deadlock in silc_task_queue_wakeup in the file
2767 lib/silcutil/silctask.c.
2769 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2771 * Added new function silc_schedule_wakeup that is used in
2772 multi-threaded environment to wakeup the main thread's
2773 schduler. It needs to be used when a thread adds a new task
2774 or removes a task from task queues. After waking up, the
2775 scheduler will detect the task queue changes. If threads
2776 support is not compiled in this function has no effect.
2777 Implemented the wakeup mechanism to both Unix and WIN32
2778 systems. Affected files are lib/silcutil/silcschedule.[ch],
2779 lib/silcutil/unix/silcunixschedule.c and the
2780 lib/silcutil/win32/silcwin32schedule.c.
2782 * Added new function silc_task_queue_wakeup to wakeup the
2783 scheduler by the specified task queue. Affected file
2784 lib/silcutil/silctask.[ch].
2786 * The silc_socket_host_lookup_start now wakes up the scheduler
2787 after adding the timeout task. Affected file is
2788 lib/silcutil/silcsockconn.c.
2790 * The silc_socket_host_lookup is synchronous now if the threads
2791 support is not compiled in. However, the callback is still
2792 called asyncronously through the scheduler, anyway. Affected
2793 file lib/silcutil/silcsockconn.c.
2795 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2797 * Added new function silc_socket_host_lookup to perform
2798 asynchronous IP and FQDN lookups for the socket connection.
2799 Affected files lib/silcutil/silcsockconn.[ch].
2801 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2803 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2804 that may or may not compile the mutex support in.
2806 Changed the silc_mutex_alloc interface. It allocates the
2807 mutex now to the sent pointer and returns TRUE or FALSE.
2809 Affected file lib/silcutil/silcmutex.h.
2811 * Wrote the SILC Task Queue interface to support multi-threads.
2812 Affected file lib/silcutil/silctask.[ch].
2814 * Wrote the SILC Scheduler to support multi-threads. Affected
2815 file lib/silcutil/silcschedule.c.
2817 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2819 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2820 in lib/silcutil/win32/.
2822 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2824 * Defined SILC Mutex API and SILC Thread API and implemented
2825 them for Unix. Affected files are
2826 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2827 lib/silcutil/unix/silcunixmutex.c and
2828 lib/silcutil/unix/silcunixthread.c.
2830 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2832 * Fixed the silc_server_remove_clients_by_server's channel
2833 key re-generation. The hash table handling was incorrect
2834 and would not work with many channels. Affected file is
2837 * Fixed some memory leaks around the server code.
2839 * Rewrote the silc_server_get_users_on_channel to support IPv6
2840 based Client ID's. Affected file silcd/server.c.
2842 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2843 specification. However, a separate document must be written
2844 to define the detailed signing procedure and the payload
2845 associated with the flag. Defined the flag to the
2846 lib/silccore/silcchannel.h as well.
2848 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2850 * Changed the dynamic tables to static size tables in the
2851 lib/silccrypt/silchmac.c.
2853 * Removed GCC dependencies from the code. A patch by cras.
2855 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2857 * Do not show the error "Error receiving packet bla bla"
2858 in server if it really was not an error (-2 means that reading
2859 is pending). Affected file silcd/server.c.
2861 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2863 * Fixed a possible crash in silc_server_remove_clients_by_server
2864 in silcd/server.c. Fixed there also some memory leaks.
2866 * Fixed the silc_idlist_replace_client_id. It could replace
2867 wrong key in the hash table. Affected file silcd/idlist.c.
2869 * Do not check whether there are global users on the channel
2870 if the channel->global_users is FALSE. Affected functions
2871 silc_server_remove_from_one_channel and
2872 silc_server_remove_from_channels in silcd/server.c. Also,
2873 do not check if the removed client is local as we can be
2874 sure that global client was not removed from the channel
2875 and checking for global users is not needed.
2877 * The silc_server_remove_clients_by_server now re-generates
2878 the channel keys correctly for those channels that had
2879 clients removed from them. Affected file silcd/server.c.
2881 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2883 * Found the reason of random crashes in the server. We weren't
2884 ignoring the SIGPIPE signal (which can be sent in write())
2885 and it crashed the server. Affected file silcd/silcd.c.
2887 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2889 * Assure that sock->user_data is not NULL in the function
2890 silc_server_packet_send in silcd/packet_send.c.
2892 * Disconnect the remote connection if it could not be added
2893 to any ID lists in the server. The affected file is
2896 * Check in silc_server_packet_send[_real/dest] that the
2897 socket is not disconnecting and ignore the data if it is.
2898 Affected file silcd/packet_send.c.
2900 * Define inline to __inline on native WIN32 compilation.
2901 Affected file includes/silcwin32.h.
2903 * Added some explicit type casts for inline code since MSVC
2904 require them. Affected files lib/silcutil/silcbuffer.h,
2905 lib/trq/silcdlist.h and lib/trq/silclist.h.
2907 * Print warning in log files from now on if the packet
2908 decryption fails. Affected file silcd/server.c.
2910 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2912 * Changed the `say' client operation's interface to accept
2913 new `type' argument to indicate the type of the message sent
2914 by the library. The application may filter the library's
2915 messages according the type. The affected file is the
2916 lib/silcclient/silcapi.h.
2918 * Added two new functions to lib/silcclient/silcapi.h:
2919 silc_client_del_client and silc_client_del_client_by_id.
2920 Affected file lib/silcclient/idlist.c.
2922 * Moved the clientincludes.h from includes/ to silc/ and
2923 serverincludes.h from includes/ to silcd/.
2925 * The modes for the CMODE and CUMODE are now passed as
2926 uint32 for application with COMMAND_REPLY. The affected
2927 file is lib/silcclient/command_reply.c.
2929 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2931 * /WHOIS without arguments shows client's own information.
2932 Affected file lib/silcclient/command.c.
2934 * Changed PING to not accept any arguments. The specs
2935 says that client can ping only the connected server so
2936 requiring an argument is not needed. Affected file is
2937 lib/silcclient/command.c.
2939 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2941 * Fixed a fatal bug in private message sending and reception
2942 encryption and decryption when using private message keys.
2943 The implementation was incorrect and did not follow the
2944 specification. It causd that some of the message were
2945 lost since it did not use the sending and receiving keys
2946 as the protocol suggests. This has been fixed and will cause
2947 incompatibilities with older clients when sending private
2948 message encrypted with private message keys. Affected files
2949 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2950 and various other in Irssi SILC Client.
2952 Added `responder' boolean argument to the functions
2953 silc_client_add_private_message_key[_ske] to indicate when
2954 the key is added as responder or initiator of the key
2957 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2959 * Removed the silc_ske_check_version function and created
2960 a SilcSKECheckVersion callback. Added also a function
2961 silc_ske_set_callbacks that is now used to set all SKE
2962 callbacks. The callback functions are not given to
2963 the SKE functions anymore, but this function is used to
2966 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2968 * Added `silc_version' argument to the silc_client_alloc
2969 to define the version of the application for the library.
2970 The library will use the version string to compare it
2971 against the remote host's (usually a server) version
2972 string. Affected file lib/silcclient/silcapi.h
2974 * Added the KE protocol context to Key Agreement context
2975 in client library so that we can abort the SKE if it
2976 is in process when we get timeout. Affected file is
2977 lib/silcclient/client_keyagr.c.
2979 * Do not resolve the client ID forever if it returns in the
2980 first time that such client does not exist. This was done
2981 for example with private message. Affected file is
2982 lib/silcclient/client_prvmsg.c.
2984 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2986 * Do not add regex.h for WIN32. The affected file
2987 includes/silcincludes.h.
2989 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2990 not work yet 100%. It generates the DLL's automatically
2991 when compiling with --with-win32 under cygwin.
2993 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2995 * lib/contrib/regex.c is not compiled on WIN32.
2997 * Added silc_net_get_socket_opt function to the
2998 lib/silcutil/silcnet.h.
3000 * Added includes/silcwin32.h for WIN32 specific includes
3003 * Do not use ptime structure or any of the posix process
3004 functions on WIN32 in lib/silccrypt/silrng.c.
3006 * Added silc_gettimeofday to provide generic function
3007 for struct timeval on all platforms. Added the function
3008 to lib/silcutil/silcutil.h.
3010 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3012 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3013 library as they clearly belong there. As a plus side we
3014 can make the actual socket connection routines platform
3017 Added also new generic function silc_socket_read and
3018 silc_socket_write (that used to be silc_packet_[read/write].
3019 The implementation of these are platform specific.
3021 * Added WIN32 specific routines of silc_socket_[read/write]
3022 to lib/silcutil/win32/silcwin32sockconn.c.
3024 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3026 * Added preliminary support for native WIN32 compilation under
3027 cygwin (using the -mno-cygwin option for GCC) to the
3028 ./configure.in.pre. The --with-win32 now prepares the
3029 compilation for native WIN32.
3031 * Rewrote the SILC Scheduler interface in the file
3032 lib/silcutil/silcschedule.h. The scheduler is now context
3033 based and does not have anymore any global static scheduler.
3034 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3035 and created lib/silcutil/win32 directory for WIN32 based
3038 * Added Unix specific network routines to the
3039 lib/silcutil/unix/silcunixnet.c and the old
3040 lib/silcutil/silcnet.c includes now only generic routines.
3042 Added WIN32 specific network routines to the
3043 lib/silcutil/win32/silcwin32net.c.
3045 * Added Unix specific utility functions from the
3046 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3048 * Added WIN32 SILC Scheduler to the file
3049 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3052 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3054 * Do not handle JOIN notify in the server if the target client
3055 is not registered (idata->registered == FALSE). The affected
3056 file is silcd/packet_receive.c.
3058 * Update the nickrec->founder in event_cumode in the Irssi SILC
3059 client. Affected file irssi/src/silc/core/silc-channels.c.
3061 * Fixed the CUMODE_CHANGE notify handling in the server when
3062 server and router are announcing their clients on channels.
3063 Now the mode changes are saved and notified correctly. The
3064 affected file is /silcd/packet_receive.c.
3066 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3067 They really did not replace the cache entry in the ID Cache.
3068 Now they do that. Affected file silcd/idlist.c.
3070 * Fixed the KICK notify handling in the Irssi SILC client to
3071 update the channel records so that the kicked client does not
3072 appear to be on the channel. The affected file is
3073 irssi/src/silc/core/silc-channels.c.
3075 * Always update the conn->current_channel when executing command
3076 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3078 * Fixed the KILL notify handling in Irssi SILC client to remove
3079 the killed client on all channels.
3081 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Fixed the silc_parse_command_line to remove extra spaces
3084 from the start and end of the arguments. Affected file is
3085 lib/silcutil/silcutil.c.
3087 * Cancel and free any active protocol in the function
3088 silc_server_close_connection. Affected file silcd/server.c.
3090 * Cancel and free any active protocol in the function
3091 silc_client_close_connction. Affected file is
3092 lib/silcclient/client.c.
3094 * Do not execute the KILL command for clients that are in
3095 history (ie. they are not in the network). Affected file is
3098 * Fixed KILL notify handling, client does not crash anymore.
3099 Affected file irssi/src/silc/core/silc-channels.c.
3101 * Reduced the default packet buffer size from 2048 to 1024 in
3102 lib/silccore/silcpacket.c.
3104 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3105 counter to the SKE context that is incresed when the SKE library
3106 performs async operation outside the library. If the outside
3107 process frees the SKE context and FREED status will be set
3108 and the library will detect after the sync operation that the
3109 libary is freed. The affected files are
3110 lib/silcske/silcske[_status].[ch].
3112 * Resolve the client entry information in the function
3113 silc_client_channel_message to assure that NULL pointer is not
3114 passed as client entry to the application. */
3116 * Fixed the task timeout calculation to assure that there is
3117 never negative timeouts. The affected file is
3118 lib/silcutil/silcschedule.c.
3120 * Fixed the channel user mode notification sending in server.
3121 It was sent point-to-point to the router (or to server by router)
3122 but it needs to be destined to a channel. The routines now
3123 supports sending the channel user mode notifys to the channels
3124 when announcing clients and channels. Affected files are
3125 silcd/server.c and silcd/packet_receive.c.
3127 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3128 It did not actually replace the old channel entry in the cache.
3129 Affected file lib/silcclient/client_notify.c.
3131 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3133 * Fixed a possible crash in silc_packet_send_prepare. It now
3134 assures always that there is enough space in the buffer and
3135 at the tail area of the buffer (for MAC).
3137 Fixed the inbound buffer reallocation in silc_packet_read.
3138 It was old code and did not handle the reallocation correctly.
3141 The affected file is lib/silccore/silcpacket.c.
3143 * Fixed buffer overflow in silc_parse_nickname in the file
3144 lib/silcutil/silcutil.c.
3146 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3148 * make install generates new server keys only if there is not
3151 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3153 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3154 Added check that if the NOREPLY is set then we will not send
3155 the away message. This avoids infinite loop of away messages
3156 if both clients are away. The affected file is
3157 lib/silcclient/client_prvmsg.c.
3159 * Fixed client crash if /NICK was given without arguments.
3160 Affected file lib/silcclient/command.c.
3162 * Server does not send the invite list in INVITE command back
3163 to the client if the list was not altered. Added this notion
3164 to the protocol spec as well. Affected file silcd/command.c.
3166 Fixed possible crash in INVITE command by checking the
3167 value of silc_server_get_client_route command.
3169 * Fixed the INVITE notify type handling. The arguments are now
3170 taken in correct order and client does not crash. The affected
3171 file is irssi/src/silc/core/silc-channels.c.
3173 Removed the "Inviting xxx to channel" message from the
3174 client library away and let the application handle it.
3175 Affected file lib/silcclient/command.c. Added that message
3176 to Irssi SILC client's message formats.
3178 * Fixed CMODE command crash in client. It now checks the
3179 amount of arguments correctly and does not crash. The affected
3180 file is lib/silcclient/command.c.
3182 * Do not create new channel automatically in silc_channels_join
3183 but check whether the channel by that name already exists.
3184 Affected file irssi/silc/core/silc-channels.c.
3186 * Do not send the SERVER_SIGNOFF to router if the disconnected
3187 entity was the router. Affected file silcd/server.c.
3189 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3190 SILC client as it was missing from there.
3192 Added the handling of the KICK notify to the Irssi SILC client
3193 as it was missing. Added "you have been kicked" message to
3194 Irssi SILC client's message modules formats.
3196 Added the handing of the KILL notify to the Irssi SILC client
3197 as it was missing. Added the kill message module formats
3200 The affected file is irssi/src/silc/core/silc-channels.c.
3202 * The router did not save the channel mode the server announced.
3203 Affected file silcd/packet_receive.c.
3205 * Fixed a possible crash in INFO command in server. If the
3206 server did not provide the server info it crashed. Affected
3207 file silcd/command.c.
3209 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3211 * Fixed the GETKEY command in the server to check also the
3212 global list. Otherwise the GETKEY would not work correctly
3213 in normal SILC server. Affected file silcd/command.c.
3215 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3217 * Fixed GETKEY crash, it crashed if the command did not succseed.
3219 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3221 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3222 is now real and not just an macro interface to GMP.
3224 Removed the entire GMP from the source tree and imported new
3225 NSS MPI library instead. Reason for removing GMP is that it is
3226 extremely large and compiles extremely slow. The NSS MPI
3227 is only a few files and compiles in less than 10 seconds.
3228 The speed is also about the same as GMP. The MPI is imported
3229 to lib/silcmath/mpi.
3231 If the system has GMP installed we will still use the GMP.
3232 If it is not then the NSS MPI will be compiled.
3234 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3236 * Merged a long nickname (127 characters long) crash bugfix from
3237 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3239 * Merged a freed memory reference bugfix from Irssi CVS tree.
3240 Affected file irssi/src/core/commands.c.
3242 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3244 * Added the server's public key sving and verification to the
3245 server when performing the SKE. This was missing and the
3246 remote server's (or router's) public key was accepted without
3247 checking whether we have it previously or trust it at all.
3248 Affected file silcd/protocol.c.
3250 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3252 * Check in the silc_server_timeout_remote if protocol is active
3253 and make sure that the protocol's final callback is called so
3254 that all memory if freed. Affected file silcd/server.c.
3256 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3258 * silc_server_whois_send_reply crashed the server if the nickname
3259 was 127 characters long. Affected file silcd/command.c.
3261 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3263 * Added sanity check to the silc_server_new_client. If the hostname
3264 is provided inside username then check that the provided hostname
3265 really is the same as the resolved one. If the hostname was not
3266 resolved then check it from the public key. Affected file is
3267 silcd/packet_receive.c.
3269 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3270 if the server disconnected us and the connection is not valid
3271 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3273 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3274 the library to the lib/silcutil/silcutil.[ch].
3276 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3278 * Close log file after open. Affected file
3279 lib/silcutil/silclog.c.
3281 * Check whether sock == NULL in silc_client_send_packet and return
3282 if it is. Affected file lib/silcclient/silcclient.c.
3284 * Check rec->entry == NULL in the Irssi SILC Client before
3285 sending the channel message. Affecte file is
3286 irssi/src/silc/core/silc-servers.c.
3288 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3290 * Merged a splitted window bugfix from Irssi CVS tree. The
3291 affected file is irssi/src/fe-text/textbuffer-view.c.
3293 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3294 It did not print nickname.
3296 * Improved the distributions system a bit.
3298 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3300 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3301 irssi/src/fe-text/gui-window.c.
3303 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3304 to in-active server. The affected file is
3305 irssi/src/silc/core/client_ops.c.
3307 * Resolve the client in USERS command reply if the entry does
3308 not have username resolved. The affected file is
3309 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3310 command to WHOIS command to really resolve stuff. The USERS
3311 is not used any more in any critical section so WHOIS can
3312 be used even though it might be slower than IDENTIFY.
3314 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3317 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Changed the protocol API a bit more consistent in the
3320 lib/silccore/silcprotocol.[ch].
3322 * Changed the following headers to ROBODoc format:
3324 lib/silccore/silcpayload.h
3325 lib/silccore/silcprotocol.h
3326 lib/silccore/silcsockconn.h
3328 All core library headers are now formatted.
3330 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3332 * Fixed a bug in Irssi SILC client; do not show that you are
3333 server/router operator if you really are not. Affected file is
3334 irssi/src/silc/core/client_ops.c.
3336 * Renamed silc_command_free_payload to silc_command_payload_free.
3337 Affected file lib/silccore/silccommand.h
3339 * Added silcmath.h to include the prototoypes of various routines
3340 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3343 * Changed the following headers to ROBODoc format:
3345 lib/silccore/silcchannel.h
3346 lib/silccore/silccommand.h
3347 lib/silccore/silcid.h
3348 lib/silccore/silcidcache.h
3349 lib/silccore/silcmode.h
3350 lib/silccore/silcnotify.h
3351 lib/silccore/silcpacket.h
3352 lib/silcmath/silcmath.h
3354 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3356 * Added checking to the server code not to start the server if
3357 ciphers and stuff are not configured properly. Affected files
3358 silcd/serverconfig.[h] and silcd/server.c.
3360 * Changed the layout of the header files of the public interfaces
3361 in the SILC libraries. The new layout supports ROBODoc
3362 documentation tool (and some others) so that it is easy to create
3363 a library reference manual. All the other headers and source
3364 code must still follow the CodingStyle document. Also source
3365 code must not include these ROBODoc stuffs, only the headers.
3366 Furthermore, all public interface headers must now be named
3367 by using `silc' prefix, example: silcapi.h, silccipher.h.
3368 Some files were renamed due to this. All the other headers
3369 must not be used as public interfaces. I will update the
3370 CodingStyle document later. Changed following headers, so far:
3372 lib/silcclient/silcapi.h
3373 lib/silccore/silcauth.h
3374 lib/silccore/silcprivate.h
3375 lib/silccrypt/silcdh.h
3377 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3381 * Removed silc_client_packet_send_flush from the client library
3382 as it is not needed. Affected file lib/silcclient/client.[ch].
3384 * Added printing of message of unresolved authentication method
3385 to the Irssi SILC client. Added it to the module formats.
3386 Removed the same message from the client library.
3388 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3390 * Added new distribution feature, DISTLABEL. Every distribution
3391 can define own preprocessor label that can be used in the
3392 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3393 file distributions, acconfig.h.pre and prepare.
3395 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3397 * Added Makefile.defines_int to include the actual definitions
3398 for Makefile.defines.in. Tested the new distribution system,
3399 created distributions and tested installation.
3401 * Added AWAY message printing to the Irssi SILC client. Added
3402 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3404 * Added SCONNECT command to call the SILC's CONNECT command.
3405 Cannot use CONNECT directly since Irssi uses that internally.
3406 Affected file irssi/src/silc/core/silc-servers.c.
3408 Added ACTION local command. It is same as ME command but takes
3409 the channel as mandatory argument.
3411 Rewrote some of the Irssi's help files to suite for SILC
3414 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3416 * Added Makefile.defines[.in] that should for now on be included
3417 in all Makefile.am file in the source tree. That file includes
3418 all common compilation definitions for SILC source tree.
3420 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3422 * Minor changes to the ./prepare script to change the package
3423 name according the distribution name to the configure.in.
3425 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3427 * Created new distribution system. Added file `distributions'
3428 that defines all the distributions that can be created out of
3429 the SILC source tree. The ./prepare script now reads that
3430 file to determine how to prepare the distributions. The
3431 first argument to the ./prepare is the name of the distribution
3432 and second is the version of the distribution. If given
3433 without arguments it creates the default (toolkit) distribution
3434 with the default version (defined in ./prepare).
3436 All Makefile.am files that are subject to the distributions
3437 are now named as Makefile.am.pre. These are ./Makefile.am
3438 and lib/Makefile.am. Others may be changed later.
3440 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3442 * Added invite list, ban list, some key management and connection
3443 error message printing to module formats in the Irssi SILC client.
3445 * Added new silc_client_set_away_message to set the away message
3446 that is back to the person who sent private message. The
3447 affected file lib/silcclient/silcapi.h and the
3448 lib/silcclient/client_prvmsg.c.
3450 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3452 * Fixed the private message sending in the Irssi SILC client,
3453 added local command KEY to the Irssi SILC client.
3455 Added key management and key agreement message formats to the
3456 irssi/src/fe-common/silc/module-formats.[ch].
3458 Added USERS (alias WHO) printing, server/router operator
3459 indication and LIST command printing to the module formats.
3461 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3463 * Fixed channel joining notify handling, cumode notify handling
3464 from Irssi SILC client.
3466 * Added SILC specific module-formats to the Irssi SILC client so
3467 that SILC specific message hilighting, colors etc is possible.
3468 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3470 Added channel mode, channel user mode, actions, notices,
3471 whois and whowas printing to the the module-formats.c.
3473 * Fixed a bug in channel deletion in the server. The channel
3474 is not left to the cache even if the channel founder auth mode
3475 is set when there are no users anymore on the channel. Affected
3476 file silcd/server.c.
3478 * The silc_net_localhost now resolves the entire hostname including
3479 the domain name. Affected file lib/silcutil/silcnet.c.
3481 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3483 * Changed the ask_passphrase client operation to be ascynchronous.
3484 It has now a completion callback and a context that the
3485 application must call after it has got the passphrase from
3486 the user. Affected files lib/silcclient/silcapi.h,
3487 lib/silcclient/protocol.c, lib/silcclient/command.c and
3490 Added SilcAskPassphrase callback that the application calls
3491 to deliver the passphrase to the library.
3493 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3494 The public key verification and especially a certificate
3495 verification is asynchronous procedure.
3497 Added new SILC_SKE_STATUS_PENDING status to indicate the
3498 request is pending and a callback will be called to finalize
3501 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3502 indicate that remote end did not send its public key (or
3503 certificate), even though we require it. Added check for this
3504 condition in the SKE. This was a security bug, now fixed.
3506 Defined new SilcSKEVerifyCbCompletion callback that is called
3507 when the verification process is completed.
3509 The affected files lib/silcske/silcske_status.h and
3510 lib/silcske/silcske.[ch].
3512 * Changed the verify_public_key client operation to be async
3513 as well. Defined SilcVerifyPublicKey callback that is used to
3514 indicate the success of the public key verification process.
3516 Changed the server and client to use the new async client
3519 * Changed the Irssi SILC client's internal scheduler to be called
3520 twice as many times as it used to be. As a result the client
3521 should be a bit faster now. Affected file is
3522 irssi/src/silc/core/silc-core.c.
3524 * Added support to Irssi SILC client of asynchronous public key
3525 verification and passphrase inquiry. Affected file is
3526 irssi/src/silc/core/silc-core.c.
3528 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3530 * Do not say "You have left channel %s" in client library.
3531 Moved it to the application. Affected files are
3532 lib/silcclient/command.c and silc/client_ops.c.
3534 * Fixed silc_client_get_clients. Command context was not
3535 duplicated and was freed memory in the callback. Affected
3536 file lib/silcclient/idlist.c.
3538 * Do not say "you are now talking..." on JOIN command in the
3539 client library. The appliation must handle it.
3541 * Do not say ".. changed topic to" in command reply in the
3542 client libary. The application must handle it.
3544 * Fixed TOPIC command sending in the client library.
3546 * Fixed a memory leak in silc_client_command_free in the file
3547 lib/silcclient/command.c.
3549 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3551 * Imported a modified version of Irssi client to the source tree.
3552 The Irssi will be used to create a new client called
3553 Irssi SILC. Imported to irssi/.
3555 Added silc_core_init_finish function to the Irssi. Affected
3556 file irssi/configure.in.
3558 A lot changes in the Makefile.ams around the irssi tree.
3560 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3562 * Do not rehash if the new size is same as the old size of the
3563 hash table, in the silc_hash_table_rehash*. The affected file
3564 lib/silcutil/silchashtable.c.
3566 * Replaced hash_table_del_by_context calls from the server
3567 (when channel->user_list and client->channels) to the
3568 hash_table_del as it is sufficient and faster.
3570 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3572 * Added silc_hash_table_list, silc_hash_table_get and the
3573 SilcHashTableList structure to provide an alternative way to
3574 traverse the hash table. The affected files are
3575 lib/silcutil/silchashtable.[ch].
3577 * Changed the server's idlist routines to use the hash table
3578 routines to optimize the code.
3580 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3582 * Replaced the client entry's `channel' list and channel entry's
3583 `user_list' list to hash tables for optimized lookup. Changed
3584 the code to use the hash table interface around the code.
3585 Affected file lib/silcd/idlist.[ch].
3587 * Added `auto_rehash' boolean argument to the function
3588 silc_hash_table_alloc to indicate whether the hash table should
3589 auto-rehash when it thinks is appropriate time. It will
3590 increase the hash table size if the there is twice as much
3591 entries in the table than the size of the table, and will
3592 decrease the size if there are twice as less entries than
3593 the size of the table.
3595 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3597 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3599 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3601 * silc_idcache_purge_by_context deletes the entry now by context
3602 as it is supposed to do. Affected file lib/silccore/idcache.c.
3604 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3605 client is not anymore valid (WHOWAS givens the info) and not
3606 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3608 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3610 * Removed the `data' and `data_len' arguments from the ID Cache
3611 interfaces and added `name' argument. ID Cache does not handle
3612 anymore the binary data only a names associated with given ID.
3614 * When hashing a Client ID with silc_hash_id the entire ID is
3615 not hashed anymore, instead only the hash of the Client ID is
3616 hashed. This way we can access the Client ID from the cache
3617 with Client ID but with the hash of the ID (which is a hash of
3618 the nickname) as well without any difference in performance.
3620 Added also silc_idcache_find_by_id_one_ext to do one on one
3621 searching when we have the actual ID. Added also function
3622 silc_hash_client_id_compare. The affected files are
3623 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3625 * When hashing the name associated with a ID it is always done
3626 in lowercase. This way we can access the cache without worrying
3627 about case-sensitivity, even though, for example nicknames are
3630 * Fixed a bug in server with channel message sending. It put
3631 wrong ID type as destination ID. The affected file
3632 silcd/packet_send.c.
3634 * silc_idcache_del_by_context now deletes from all hash tables
3635 by context. Affected file lib/silccore/idcache.c.
3637 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3639 * Changed the client library to use the new ID Cache interface.
3640 Changes around the source tree.
3642 * Added silc_hash_table_rehash_ext to rehash with specific
3643 hash function. Affected file lib/silcutil/silchashtable.[ch].
3645 * Added silc_hash_string_compare to compare two strings in the
3646 hash table. Affected file lib/silcutil/silcutil.[ch].
3648 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3650 * Added new function silc_idcache_del_by_context into the
3651 lib/silccore/idcache.[ch].
3653 * Changed the server's ID list routines to use the new ID Cache
3654 interface. Changes around the source tree.
3656 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3658 * Added silc_hash_table_del[_by_context]_ext functions in to the
3659 lib/silcutil/silchashtable.[ch].
3661 Removed silc_hash_table_find_all* routines and added new
3662 silc_hash_table_find_foreach to replace them.
3664 Added silc_hash_table_replace_ext function as extended
3665 replacing function. Separated the simple hash table interface
3666 from the extended hash table interface in the file
3667 lib/silcutil/silchashtable.h.
3669 * Fixed minor bugs and changed it to use some of the new
3670 hash table functions in lib/silccore/idcache.c
3672 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3674 * Added new function silc_hash_table_find_all to return all keys
3675 in the hash table by the specified key. As the hash table is
3676 collision resistant it also makes it possible to have several
3677 duplicate keys in the hash table. This function may be used to
3678 find all of the keys from the hash.
3680 Added user_context arguments to the SilcHashFunction,
3681 SilcHashCompare and SilcHashDestructor to deliver user specified
3684 Added new fuctions silc_hash_table_find[_all]_ext to do
3685 extended lookup with specified hash and compare functions and
3686 specified user contexts.
3688 Added new function silc_hash_table_add_ext to add the key
3689 with specified hash function and user context.
3691 Added new function silc_hash_table_foreach to traverse all
3692 entrys in the hash table. Added SilcHashForeach callback
3695 Added new function silc_hash_table_del_by_context to delete
3696 the entry only if the context associated with the key matches.
3698 Affected files are lib/silcutil/silchashtable.[ch].
3700 * Removed silc_hash_[server/client/channel]_id and added just
3701 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3702 silc_hash_id_compare to compare two ID's using as the hash table
3703 comparison function. Added also silc_hash_data to hash
3704 binary data and silc_hash_data_compare to compare it.
3706 * Removed silc_idlist_find_client_by_hash as it is not needed
3707 anymore. Affected file silcd/idlist.[ch].
3709 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3710 to use internally the SilcHashTable. The new ID Cache is a lot
3711 faster than the old one. Some of the ID Cache interface was also
3712 rewritten and obsolete and stupid functions were removed.
3714 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3716 * Added entry_count field to the SilcHashTable to keep the number
3717 of the entries in the table. Implemented the function
3718 silc_hash_table_rehash. Added new function
3719 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3721 Fixed a minor bug in silc_hash_table_free.
3723 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3724 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3725 into the lib/silcutil/silcutil.[ch].
3727 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3729 * Implemented a collision resistant hash table into the
3730 lib/silcutil/silchashtable[ch]. See the header and the source
3731 for the SilcHashTable API.
3733 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3735 * Merged dotconf version 1.0.2 into lib/dotconf.
3737 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3739 * Do not compile anything in lib/silcsim/* if the SIM support
3740 is not enabled. The tree should now compile without problems
3743 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3745 * Compiled the SILC under cygwin. Compiled and tested briefly
3746 without problems. More tests needed. The SIMs didn't compile
3749 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3751 * Fixed possible crash in silc_get_username in the
3752 lib/silcutil/silcutil.c.
3754 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3756 * Fixed a va_arg in silc/client_ops.c.
3758 * Oops, RC5 routines were named AES and caused some problems
3759 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3761 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Added new SilcIDIP structure into the lib/silccore/id.h and
3764 replaced the old `ip' fields from all SILC ID's to that type.
3765 This is a step towards IPv6 support.
3767 The silc_id_get_len takes now the ID as an extra argument.
3768 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3769 both IPv4 and IPv6 based ID's.
3771 The affected files are lib/silccore/id.[ch] and other files
3772 around the tree using these routines.
3774 * Removed the ID length arguments in server from various
3775 silc_server_send_notify_* routines -> they are not needed
3778 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3780 * Fixed memory leak in silc_encode_pem_file in the file
3781 lib/silcutil/silcutil.c.
3783 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Check minor version as well in the SKE. Affected files are
3786 silcd/protocol.c and lib/silcclient/protocol.c.
3788 * Added --identifier option to the server so that an identifier
3789 can be when creating the public key for the server. Affected
3790 file is silcd/silcd.c.
3792 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3793 lib/silccrypt/silcpkcs.c.
3795 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3797 * Register default ciphers and stuff when using -C option with
3798 the server. Affected file sildc/silcd.c.
3800 * Put back the servers public key filename format, it is better
3801 than the new one. For now, the client keys are saved with the
3802 new filename format. The affected file silc/client_ops.c.
3804 * Implemented the Cipher API for the rest of the ciphers that
3805 did not implement it or implemented it the wrong way.
3807 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Register default ciphers and stuff when using the -S option
3810 in the client. Affected file silc/silc.c. Same also when
3811 creating new key pair with -C option.
3813 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Fixed the silc_verify_public_key client operation function to
3816 save the public keys differently. The fingerprint is now
3817 used as filename and not the hostname. This way also the
3818 client keys are saved uniquely and not with hostnames. The
3819 affected file is silc/client_ops.c.
3821 * Trimmed the silc_hash_fingerprint function to remove extra
3822 whitespaces from the end of the fingerprint. The affected
3823 file is lib/silccrypt/silchash.c.
3827 * Added silc_cipher_register_default function to register all
3828 default ciphers. It can be used when configuration files
3829 does not exist and the application does not want any specific
3830 ciphers in any specific order.
3832 The SilcDList is now used as silc_cipher_list dynamically
3833 allocated cipher list. Removed the static list all together
3834 and now all ciphers must be allocated to the dynamic list.
3835 The silc_cipher_alloc routine was changed to check only the
3838 All silc_cipher_* routines that used to return int returns
3841 The affected files lib/silccrypt/silccrypt.[ch].
3843 * The same thing was done to silc_hash_* as for silc_cipher_*
3844 routines. Affected files lib/silccrypt/silchash.[ch].
3846 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3847 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3848 Added also silc_pkcs_[un]register[_default] functions.
3849 Removed the data_context from the PKCS API.
3851 * Added silc_hmac_register_default function to register default
3852 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3853 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3854 to unregister all hmacs at once.
3856 * Register the default ciphers, hash functions, PKCSs and HMACs
3857 if client's configuration file does not exist. The affected
3860 * The client did not load the hash functions from the SIM
3861 modules at all. Added support for this. Affected file is
3862 silc/clientconfig.c.
3864 * When decoding public key with silc_pkcs_public_key_decode, check
3865 the supported algorithm only if PKCS are registered. Affected
3866 file lib/silccrypt/silcpkcs.c. The same was done with the
3867 silc_pkcs_private_key_decode.
3869 * Fixed the SILC List routines to keep the list always in order.
3870 It used to change the list's order when traversing the list but
3871 not it preserves the order. Affected file lib/trq/silclist.h.
3873 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3875 * Added the client library to use the SilcSocketConnection's
3876 reference counter (by silc_socket_dup) to prevent the bug that
3877 the socket object may be freed underneath async operation.
3879 * The name resolv library checking fixes in the configure.in.pre.
3882 * Created new version of the protocol drafts for future
3883 development. The -03 drafts are the ones that will be changed
3884 in the trunk now and the -02 will remain as they are.
3886 * Send list of CUMODE notifys to the router when announcing
3887 the channel users to the router. Affected file silcd/server.c.
3888 If the router receiving channel founder CUMODE for a channel
3889 that already has channel founder it will send CUMODE notify
3890 to the sender to remove the channel founder rights from the
3891 announced client. Affected file silcd/packet_receive.c.
3893 * The CUMODE notify may now use Server ID as well as the entity
3894 who changes the mode. Updated protocool specs.
3896 * Updated INSTALL and README files.
3898 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3900 * New web pages in the http://silc.pspt.fi. The pages was
3905 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3907 * Implemented the [DenyConnectin] config section in the server.
3908 Added silc_server_config_denied_conn to check whether incoming
3909 connection is denied. Affected file silcd/serverconfig.[ch].
3911 * Do not check the ports when checking the incoming configuration
3912 data if the port is 0, meaning any. Affected file is
3913 silcd/serverconfig.c.
3915 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3917 * Fixed buffer overflow in silc_string_compare in the file
3918 lib/silcutil/silcutil.c.
3920 * Fixed double free in silc_server_command_leave in the file
3923 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3925 * Fixed the version checking in the server. Affected file is
3928 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3930 * Fixed the configuration data fetching when accepting new
3931 connections in the server. Affected file silcd/server.c.
3933 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3935 * Added `sender_entry' argument to the function
3936 silc_server_packet_relay_to_channel so that we can check
3937 whether some destination actually belongs to the same route
3938 the sender belongs (ie, we must not resend the packet to the
3939 sender). Affected file silcd/packet_send.[ch].
3941 * Added `servername' field to the SilcClientEntry in the server
3942 to hold the name of the server where client is from. Affected
3943 file is silcd/idlist.h.
3945 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3947 * Moved the channel message encrypting in the router betwen
3948 router connections from silc_server_channel_message to the
3949 silc_server_packet_relay_to_channel since we want to check
3950 whether we have anybody channel before encrypting anything.
3951 Affected files silcd/packet_[receive/send].c.
3953 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3955 * Fixed the [AdminConnection] server config section to support
3956 multiple entries. Affected file silcd/serverconfig.c.
3958 * Added support into the server to check the validity of the
3959 incoming connection before executing any KE or authentication
3962 * The connection configuration is now saved to the KE and
3963 connection auth protocol contexts and not fetched anymore in
3964 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3966 * The local hosts listenning address and port is also resolved
3967 now when starting the server. We want to have the socket object
3968 to include the real address and port for the listener. Added
3969 new function silc_net_check_local_by_sock into the files
3970 lib/silcutil/silcnet.[ch].
3972 * Fixed a broadcast bug in server -> do not broadcast if we
3975 * Fixed a routing bug. Do not route broadcast packets ever.
3976 Broadcast packets must be processed always and not routed since
3977 they may be destined to some other host than yourself and thus
3978 would get routed without no good reason. Affected file is
3981 * Added function silc_server_config_is_primary_route to check
3982 whether primary router connection has been configured (a router
3983 configuration that we are initiating). If there is not, we
3984 will assume that there is only two routers in the SILC network
3985 and we will use the incoming router connection as our primary
3986 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3988 * Changed the order of the broadcasting. Broadcast _after_ the
3989 packet has been processed not before. Affected file is
3992 * Fixed a [ClientConnection] parsing bug. The port was never
3993 parsed correctly thus resulting to port 0. Affected file
3994 silcd/serverconfig.c.
3996 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3997 argument and did not set the broadcast packet flag. Affected
3998 file silcd/packet_send.c. Fixed same bug in the function
3999 silc_server_send_notify as well.
4001 * If we receive NEW_ID packet for our own ID in the server, ignore
4004 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4008 * Removed the nickname from the Private Message Payload.
4009 Updated the code and the protocol specs.
4011 * Updated protocol specs for submitting to the IETF.
4013 * Tweaked the Random Number Generator a bit. Affected file
4014 lib/silccrypt/silcrng.c. Exported a new function
4015 silc_rng_[global]_add_noise which can be used to add more
4018 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4020 * Do not parse packets with different timeout when protocol
4021 is active -> may cause problem with rekey. Affected file
4024 * When server receives signoff notify it must not create
4025 new channel key if the client is on any channels since the
4026 sender of the signoff notify will create it.
4028 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4030 * Added printing of error messages during SKE protocol from the
4031 failure packet sent by server during SKE. Affected file
4034 * Removed the client's failure_callback handling with timeout
4035 and handle it immediately when received.
4037 * The SKE library returned wrong type in SUCCESS and FAILURE
4038 packets. They must be 32 bit MSB not 16 bit MSB.
4040 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4042 * Ok, rewrote the logic of the re-key and now it seems to work.
4043 I tested it on high traffic with frequent re-keys without
4044 problems. Added hmac_receive (and renamed hmac to hmac_send)
4045 in SilcClientConnection in lib/silcclient/client.h and
4046 in SilcIDListData in silcd/idlist.h. Also, removed the
4047 SilcPacketParserContext's cipher and hmac fields as they are
4048 not needed anymore and actually caused some problems when
4049 the ciphers and hmac's changed underneath the packet parser.
4051 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4053 * If re-key protocol is active then process the incoming packets
4054 synchronously since we must assure that icoming packets encrypted
4055 with the old key is processed before the new keys is set to
4056 use. This is true other packets than for REKEY packets.
4057 Affected file silcd/server.c. The same was done to client library
4058 as well, affected file lib/silcclient/client.c.
4060 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4062 * Fixed bug in client and server to accept the force send if
4063 the packet is send from silc_[server/client]_packet_process
4064 function. Otherwise the packets are never delivered, oops.
4066 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Disable force sending of packets when REKEY protocol is active.
4069 We must assure that no packet is sent directly when rekey is
4070 performed. All packets must be sent through packet queue.
4071 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4072 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4073 function is silc_[server/client]_packet_send_real to check
4076 * Replaced the SIM paths from example config files to
4077 /usr/local/modules. Also, make install creates now
4078 /usr/local/silc/logs directory to hold all the SILC server
4081 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4083 * Made the configure.in.pre work on Solaris. Patch by salo.
4085 * Made all ciphers compatible with non-x86 machines. Defined
4086 CBC mode macros into lib/silccrypt/ciphers_def.h.
4088 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4090 * Fixed the make install.
4092 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4094 * When MAC computation fails the silc_packet_decrypt returned 0
4095 even though it was supposed to return -1. Fixed this. The
4096 affected file is lib/silccore/silcpacket.c.
4098 * Do not replace the config files in /etc/silc (in make install)
4099 if they already exist. Affected file ./Makefile.am.
4101 * Do not send re-key packets immediately but through packet queue.
4102 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4104 * Changed silc_net_check_host_by_sock to return FALSE if the
4105 IP/DNS could not be resolved. Though, it returns the IP address
4106 now even if it could not resolve it (but returns also FALSE).
4107 Affected file lib/silcutil/silcnet.[ch].
4109 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4111 * Added silc_pkcs_decode_identifier to decode the public key's
4112 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4113 Added also silc_pkcs_free_identifier. Added also new context
4114 SilcPublicKeyIdentifier.
4116 * Added -S option to the silc client. It is used to dump the
4117 contents of the specified public key file.
4119 * Changed the PKCS api to return the public key length when
4120 setting the public key.
4122 * Fixed a fatal bug in the public and private key file loading.
4123 Affected file lib/silccrypt/silcpkcs.c.
4125 * Execute the packet parsing for client with zero (0) timeout
4126 if the protocol is active. Affected file silcd/server.c.
4128 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Made the key generation options to the silcd program. Added
4131 -C option, equivalent to client's option.
4133 * Added new [ServerKeys] config section to the server. It
4134 configures the server's public and private key.
4136 * Defined generic Public Key Payload into the protocol
4137 specification to send specific type of public keys and
4140 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4141 public key or certificate.
4143 * Implemented the GETKEY command to the server and to the
4144 client library and on user interface.
4146 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4148 * Made preliminary `make install' work.

4177 SilcClientConnection structure; not needed. Affected file is
4178 lib/silcclient/client.h.
4182 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4184 * Do not ask whether user wants to use the negotiated private key
4185 for private messages, just use it. Affected file is
4186 silc/local_command.c.
4188 * Added `send_enc_key' and `enc_key_len' fields to the
4189 SilcIDListData structure since they are needed in the re-key
4190 phase. Affected file is silcd/idlist.[ch].
4192 * Implemented the simple re-key protocol into the server.

4204 the PFS is to be performed in the re-key. Affected file is
4207 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4210 int64 of at least the xintXX size. If void * is less that 4
4211 bytes uint32 * will be used. Defined bool as boolean.
4213 * Changed _ALL_ unsigned long and unsigned int to uint32,
4214 unsgined short to uint16 in the source tree.
4216 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4217 not handle clients that has entry->data.registered == FALSE.
4218 They are not in the network anymore. Affected file is
4221 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4223 * Implemented the sending of the SERVER_SIGNOFF notify in the
4224 server. Affected file is silcd/server.c.
4226 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4227 Added also silc_notify_payload_encode_args into the

4230 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4231 Affected file silcd/packet_receive.c.
4233 * Implemented the SERVER_SIGNOFF notify handling in the client
4234 library. Affected file lib/silcclient/client_notify.c. Also,
4235 implemnted the printing of the SERVER_SIGNOFF info to the
4236 application. Affected file silc/client_ops.c.
4238 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4239 if the deleting was successful. Affected file silcd/idlist.[ch].
4241 * Added support for public key authentication in the connection
4242 authentication protocol in the client library. Affected file
4243 lib/silcclient/protocol.c.
4245 * Changed the server's silc_idlist_get_clients_by_* interface
4246 to support already allocated array so that new entries may be
4247 added to pre-allocated array. Affected file silcd/idlist.[ch].
4248 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4249 and command replies.
4251 * All command reply functions in the server now calls the
4252 pending command callback even if error occured. This way the
4253 error will be delivered to the client as well. Affected files
4254 silcd/command.c and silcd/command_reply.c.
4256 * Fixed INFO command to return local server's info if no server
4257 was provided. Affected file lib/silcclient/command.c.
4259 * Removed RESTART command for good. Updated the code and the
4262 * Rewrote parts of the task system. It is a bit simpler now.
4263 Removed unsued task priorities. The affected files are
4264 lib/silcutil/silctask.[ch].
4266 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4268 * Moved the USERS printing from the library to the application.
4269 Affected files lib/silcclient/command.c and silc/client_ops.c.
4271 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4275 * Added channel key re-key support. The re-key is perfomed
4276 only by the router and is done once in an hour. Added `rekey'
4277 field to the SilcChannelEntry in the server. Affected files
4278 silcd/server.c and silcd/idlist.h.
4280 * Added silc_task_unregister_by_context into the file
4281 lib/silcutil/silctask.[ch].
4283 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Added SILC_UMODE_GONE mode to indicate when the client is not
4286 present in the SILC network. Added also support to the local
4287 command AWAY that will set this mode. Added support of showing
4288 "xxx is gone" in WHOIS command. The USERS command shows the
4289 gone status as well.
4291 * Fixed setting server and router operator privileges in the
4292 server's UMODE command. Affected file silcd/command.c.
4294 * Merged the SKE KE1 and KE2 payloads into one payload. The
4295 new KE payload is equivalent to the old KE2 payload.
4297 Cleaned up the SKE Start Payload parsing. It now uses the
4298 simple buffer unformatting to do the parsing. A lot faster
4301 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4302 to the SKE that is used to indicate whether both of the SKE
4303 parties should perform authentication. By default only the
4304 responder performs authentication. By setting this flag also
4305 the initiator must do authentication. By default it is unset
4306 since in normal SKE case, client to server connection, only
4307 the responder should do authentication. When doing SKE between
4308 two clients both should perform authentication. Updated the
4309 code and the protocol specs.
4311 * A little fix to IDENTIFY command in the server. Search the
4312 client first by hash not nickname. Affected file is
4315 * Fixed the silc_client_close_connection to support closing
4316 the client to client connections wihtout deleting too much
4317 data. Affected file lib/silcclient/client.c.
4319 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4320 are received if protocol used to be active but is not anymore
4321 the application would crash due to NULL pointer dereference.
4322 Affected files silcd/server.c and lib/silcclient/client.c.
4324 * Added `hash' field to the SilcClientConnection to include
4325 the hash function negotiated in the SKE protocol.
4327 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4328 to set the channel founder authentication data. A client can
4329 claim the founder rights later by providing the authentication
4330 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4331 This way the channel founder can regain the channel founder
4332 privileges even it is left the channel. This works only on
4333 local server and the client must be connected to the same
4334 server to be able to regain the founder rights. Updated the
4335 protocol specs accordingly.
4337 Added support to the CMODE command in the client to set the
4338 founder auth data. Read the README to see how to set it.
4340 Added support to the CUMODE command to claim the founder
4341 rights. Read the README to see how to do it.
4343 Added support for the founder authentication to the Channel
4344 Entry in the server. Affected file silcd/idlist.h.
4346 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4347 server's CMODE command. Affected file silcd/command.c.
4349 * Added the following new functions into lib/silccore/silcauth.[ch]:
4350 silc_auth_get_method and silc_auth_get_data.
4352 * The server now saves the remote hosts public key to the
4353 SilcIDListData pointer. Affected file silcd/protocol.c.
4355 * The normal server now does not remove the channel entry from
4356 the cache if the founder authentication data is set. It used
4357 to remove it if the founder was the last one on the channel on
4358 the server and left the channel. The auth data is saved and
4359 if the channel is re-joined later the old entry is used with
4360 the old auth data. Affected files silcd/command_reply.c and
4363 * Removed the `pkcs' field from the SilcIDListData structure
4364 in the server; it is not used. Affected file silcd/idlist.h.
4366 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4368 * Fixed packet processing on slow links. Partial packets were
4369 never re-processed because the incoming data buffer was cleared
4370 by the application. Application must not directly clear the
4371 sock->inbuf, the packet processing routines handle it. Fixed
4372 this in client library and in server.
4374 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4376 * Fixed the WHOIS and IDENTIFY send reply function to really
4377 check whether to send list or just one entry. Affected file
4380 * Cleaned up the LEAVE command's channel key distribution. The
4381 affected file silcd/command.c.
4383 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4384 can enforce the channel mode as well. In that case the ID
4385 includes the ID of the server. The code now enforces the
4386 mode change if the router have different mode than the server.
4388 * The notify client operation with CMODE_CHANGE notify can now
4389 return NULL client_entry pointer if the CMODE was not changed
4390 by client. Application must check for this.
4392 * Added <Server ID> argument to INFO command to support server
4393 info fetching by Server ID.
4395 * Added silc_server_announce_get_channel_users to get assembled
4396 packets of channel users of the specified channel. Affected
4397 file silcd/server.[ch].
4399 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4400 was freed underneath the ID Cache.
4402 * Re-announce clients when the server received CHANNEL_CHANGE
4403 notify from the router. Affected file silcd/packet_send.c.
4405 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4407 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4408 crashed since it did not handle the fact that there is no cipher
4409 called "3" and didn't check the error condition. Now fixed.
4411 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4412 flag. It can be used to send message requests.
4414 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4416 * Implemented the RESTART command in the client.
4418 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4419 notice type messages. Added notice printing to the user
4422 * The channel keys are not re-generated if the channel's mode
4423 is PRIVKEY, ie private key on the channel exists. Affected
4424 files silcd/server.c and silcd/command.c.
4426 * Fixed a little bug in channel message delivery when channel
4427 private keys are set in the server. Affected file is
4428 silcd/packet_send.c.
4430 * Changed the setting on channel->on_channel = TRUE from the
4431 silc_client_save_channel_key to the JOIN command reply. The
4432 key payload is not received if the private channel key is set.
4433 Affected file lib/silcclient/command_reply.c and the
4434 lib/silcclient/client_channel.c.
4436 * When the CMODE_CHANGE notify is sent and the channel private
4437 key mode is removed the channel key must be re-generated in
4438 other cells as well. Added this support for the router in the
4439 silcd/packet_receive.c.
4441 * Added new local command NOTICE to send notice message on
4442 channel. Affected file silc/local_command.[ch].
4444 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4446 * Added new local command ME to the client. It is used to send
4447 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4448 some action. Affected file silc/local_command.[ch].
4450 * Changed channel_message and private_message client operations
4451 to deliver the message flags to the application. Added also
4452 the `flags' arguments to the silc_client_send_channel_message
4453 and silc_client_send_private_message functions. Affected file
4456 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4458 * Redefined the Private Message Payload to support private message
4459 keys and to support the new private message flags. Updated
4460 the protocol specs. Flags makes it possible to have for example
4461 CTCP style messages.
4463 * Added new type SilcPrivateMessagePayload and defined an API
4464 for it in the lib/silcclient/silcprivate.[ch].
4466 * Tested private message private keys successfully. Tested the
4467 private message key set, unset and list commands with the new
4470 * Redefined the Channel Message Payload to include the channel
4471 message flags (equal with private message flags) to support
4472 for example CTCP style messages.
4474 * Defined some of the message (for channel and private message)
4475 flags. Updated the protocol specs and added the flags to the
4476 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4478 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4480 * Added SilcKeyAgreementStatus type to the key agreement routines
4481 to indicate the current status and error if one occured.
4482 The status types are defined in the lib/silcclient/silcapi.h.
4484 * Added new local command KEY that is used to set and unset private
4485 keys for channels, set and unset private keys for private messages
4486 with remote clients and to send key agreement requests and
4487 negotiate the key agreement protocol with remote client. The
4488 key agreement is supported only to negotiate private message keys,
4489 it currently cannot be used to negotiate private keys for channels,
4490 as it is not convenient for that purpose.
4492 * Fixed a minor pending callback setting bug in the function
4493 silc_client_get_client_by_id_resolve, now the function works.
4494 Affected file lib/silcclient/idlist.c.
4496 * Added function silc_net_get_local_port to get local bound
4497 port by socket. Added to lib/silcutil/silcnet.[ch].
4499 * Added `sockets' and `sockets_count' fields to the SilcClient
4500 object. They hold the sockets of the listenning sockets in
4501 the client. Listenning sockets may be for example the key
4502 agreement server. Affected file lib/silcclient/client.[ch].
4503 Added functions the silc_client_add_socket and the
4504 silc_client_del_socket. They are exported to the application
4507 * Added ~./silc/clientkeys to support other client's public keys.
4509 * Renamed verify_server_key client operation to verify_public_key
4510 and added one argument to indicate the type of the connection
4511 (server, client etc.).
4513 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4515 * Added silc_server_connection_auth_request to handle the
4516 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4517 silcd/packet_receive.[ch].
4519 * Added silc_server_send_connection_auth_request into the
4520 silcd/packet_send.c to send the connection auth request packet.
4522 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4525 * Fixed the public key authentication in responder side in the
4526 server. The `auth_data' pointer includes the SilcPublicKey
4527 not the path to the public key. Affected file silcd/protocol.c.
4529 * Implemented the public key authentication in the initiator side
4530 in the server. Affected file silcd/protocol.c.
4532 * Removed the [RedirectClient] config section from the server
4533 configuration. Is not needed and I don't want to implement it.
4535 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4537 * Cleaned up the CMODE command in the server. It now works
4538 correctly and supports all the modes defined in the protocol.
4539 Affected file is silcd/command.c.
4541 * Added `hmac_name' field to the SilcChannelEntry in the server
4542 to hold the default HMAC of the channel. It can be set when
4543 creating the channel (with JOIN command). Affected files
4546 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4547 type to indicate the change of the current cipher and hmac
4548 on the channel. Client can safely ignore the <cipher> argument
4549 (if it chooses to do so) since the CHANNEL_KEY packet will
4550 force the channel key change anyway. The <hmac> argument is
4551 important since the client is responsible of setting the new
4552 HMAC and the hmac key into use.
4554 * Fixed the CMODE command in the client library as well.
4556 * Tested CMODE command in router environment successfully.
4558 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Show the version of the remote client (or server) when connecting
4561 to the server. It is logged to the log file. Affected file
4562 is silcd/protocol.c.
4564 * Fixed the KILLED notify handling in the client library. The
4565 client must be removed from all channels when receiving the
4568 Also, do not remove the client entry when giving the KILL
4569 command but when the KILLED notify is received.
4571 * Removed silc_idlist_find_client_by_nickname from the server.
4572 Not needed anymore. Affected files silcd/idlist.[ch].
4574 * Implemented the CHANNEL_CHANGE notify type handling to the
4575 server. Affected file silcd/server.c.
4579 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4581 * Added silc_server_send_notify_invite to send the INVITE
4582 notify between routers.
4584 * Implemented the INVITE command correctly to the server.

4593 * Added function silc_server_get_client_resolve to find the
4594 client entry by ID from all ID lists and then resolve it
4595 (using WHOIS) if it cannot be found. Affected file is
4598 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Implemented the BAN command to the client library.
4602 * The JOIN command in the server now checks the invite list
4605 * Changed the silc_command_reply_payload_encode_va and the
4606 silc_command_payload_encode_va to support that if argument is
4607 NULL it ignores and checks the next argument. Affected file
4608 lib/silccore/silccommand.c.
4610 * Added silc_server_send_notify_ban to send the BAN notify
4611 type between routers.
4613 * Chaned the silc_notify_payload_encode to support that if
4614 argument is NULL it ignores and checks the next argument.
4615 Affected file lib/silccore/silcnotify.c.
4617 * Tested ban lists in router environment successfully.
4619 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4621 * Implemented BAN command to the server, in silcd/command.[ch].
4623 * Removed the BAN and INVITE_LIST modes from the CMODE command
4626 * Added function silc_string_match to regex match two strings.
4627 Affected files lib/silcutil/silcutil.[ch].
4629 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Redefined parts of the SilcChannelEntry in the server to support
4632 the new ban and invite lists.
4634 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4636 * Redefined the INVITE command. The same command can be used to
4637 invite individuals to the channel but also to manage the invite
4638 list of the channel (to add to and remove from the invite list).
4639 Updated the protocol specs.
4641 * Added new command SILC_COMMAND_BAN that can be used to manage
4642 the ban list of the channel. Updated the protocol specs.
4644 * Removed the channel modes: the SILC_CMODE_BAN and the
4645 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4646 in the CMODE command. The equivalent features are now available
4647 using INVITE and BAN commands. Updated the protocol specs.
4649 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4650 in the network about change in the current ban list. The notify
4651 type is not used by the client.
4653 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4654 support the invite lists.
4656 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4658 * Added new function silc_string_regexify that converts string
4659 including wildcard characters into regex string that can
4660 be used by the GNU regex library. Added into the file
4661 lib/silcutil/silcutil.[ch].
4663 Added silc_string_regex_combine to combine to regex strings
4664 into one so that they can be used as one regex string by
4665 the GNU regex library. Added into the file
4666 lib/silcutil/silcutil.[ch].
4668 Added silc_string_regex_match to match two strings. It returns
4669 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4671 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4673 * Imported GNU regex to the soruce tree into lib/contrib.
4674 Fixed some compiler warning from the regex.c.
4676 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4678 * Fixed MOTD command in the server to work in router environment.
4680 * Fixed the MOTD command in the client library to support
4681 the server argument in the command.
4683 * Added `nickname_len' argument to the silc_idlist_add_client
4684 in the server, as the `nickname' argument may be binary data
4687 * Added silc_idlist_get_channels to return all channels from
4690 * Implemented LIST command to the server. Affected file is
4693 * Implemented the LIST command to the client library and on the
4696 * Added [<user count>] argument to the LIST command reply.
4697 With private channels the user count is not shown.
4699 * Updated TODO and README.
4701 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4703 * The client entry's data.registered must be TRUE even with
4704 global client entry on global client list. The data.registered
4705 is used to check whether the client is anymore in the network,
4706 for example with WHOWAS command so it must be valid.
4708 * Fixed the WHOWAS command in the server. It now actually works
4709 in router environment. Added function into silcd/command_reply.c
4710 silc_server_command_reply_whowas_save.
4712 * Added silc_idlist_purge function to the silcd/idlist.c
4713 to periodically purge the ID Cache.

4716 environment. Added <server name> argument to the INFO command
4717 reply. Updated the protocol specs.
4719 * Fixed minor bug in silc_idcache_purge to not purge if the
4720 expire value is zero.
4722 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4723 they were buggy because of the WHOWAS information.
4725 * Fixed local command MSG to handle the async resolving of
4726 the remote client properly. It used to fail the first MSG.
4727 Affected file silc/local_command.c.
4729 * Added `data_len' field to SilcIDCache context.
4731 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4733 * Update TODO. Todo in commands in the server.
4735 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

4738 used by routers as broadcast packet to inform other routers
4739 about the changed user mode.
4741 Implemented the notify handling in the server. Affected file is
4742 silcd/packet_receive.c. Added the function
4743 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4745 * Added new generic Channel Payload and deprecated the New Channel
4746 Payload. The New Channel Payload is now the generic Channel
4749 * Added new argument `mode' to the silc_server_send_new_channel
4750 as it is required in the Channel Payload now.
4752 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4753 and created a new and real SilChannelPayload to represent the
4754 new generic Channel Payload. Implemented the encode/decode
4755 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4757 * Added silc_server_get_client_channel_list to return the list
4758 of channels the client has joined for WHOIS command reply.
4759 Affected file silcd/server.[ch].
4761 * Implemented the channel list sending in the WHOIS command reply
4762 in server and in the client.
4764 Implemented the channel list displaying on the user interface
4765 as well. Affected file silc/client_ops.c.
4767 * Added silc_channel_payload_parse_list to parse list of Channel
4768 Payloads. It returns SilcDList list of SilcChannelPayloads.
4769 Client for example can use this function to parse the list of
4770 channels it receives in the WHOIS command reply. The caller
4771 must free the list by calling silc_channel_payload_list_free.
4772 Affected files lib/silccore/silcchannel.[ch].
4774 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4776 * Added one new argument <user mode> to the WHOIS command reply
4777 to return the mode of the user in SILC. Updated the protocol

4787 * Implemented the UMODE command and user modes in general to the
4788 client library and to the user interface.
4790 * Implemented the UMODE command to the server.
4792 * The server now sends UNKNOWN_COMMAND error status if client sends
4793 unknown command. Affected file silcd/command.c.
4795 * All server commands now handle the command identifier the right
4796 way when sending the command reply to the client. The client can
4797 use to identify the command replies with the identifier.
4799 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4801 * Added silc_server_get_client_route to resolve the route to
4802 the client indicated by the client ID. Affected file is
4805 * Added silc_server_relay_packet as general function to relay
4806 packet to arbitrary destination. This deprecates functions
4807 like _send_private_message_key, _relay_notify etc. Affected
4808 file is silcd/packet_send.[ch].
4810 Removed silc_server_send_key_agreement,
4811 silc_server_send_private_message_key and
4812 silc_server_packet_relay_notify functions from the file
4813 silcd/packet_send.[ch].
4817 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4818 server. Affected file silcd/packet_receive.[ch].
4820 * Implemented the KILL command to the client. Implemented the
4821 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4822 Affected files lib/silcclient/command[_reply].c and
4823 lib/silcclient/client_notify.c. Implemented the KILL notify
4824 printing in the user inteface.
4826 * Fixed a lot silc_parse_nick memory leaks from the client
4827 library in the file lib/silcclient/command.c.
4829 * Changed the silc_server_send_notify_on_channels's `sender'
4830 argument from SilcSocketConnection to SilcClientEntry to
4831 check the sender as entry and not as connection object and not
4832 to send to the client provided as argument. The affected file
4833 is silcd/packet_send.[ch].
4835 * The notify packets that are destined directly to the client used
4836 to not to be processed by the server. Now changed that and the
4837 server processes all notify packets. After relaying the packet
4838 to the client the notify packet is processed in the server.
4840 * The silc_server_free_client_data now checks whether there is
4841 pending outgoing traffic for the client and purges the data to
4842 the network before removing the client entry.
4844 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4847 an client is killed from the SILC Network. Updated the protocol
4850 Added new function silc_server_send_notify_killed to the
4851 silcd/packet_send.[ch].
4853 * Added function silc_server_packet_relay_notify to relay notify
4854 packets that are destined directly to a client. In this case
4855 the server does not process the notify packets but merely relays
4856 it to the client. Affected file silcd/packet_send.[ch].
4858 Added also silc_server_packet_process_relay_notify to check
4859 whereto relay the notify. Affected file is
4860 silcd/packet_receive.[ch].
4862 * Implemented the KILL command to the server.
4866 * Added the backup schema desgined last fall to the protocol
4867 specs for everyone to see. The specification is in the
4868 *-spec-xx.txt draft and the packet type definitions for the
4869 backup routers is in *-pp-xx.txt draft. Thusly, added also
4870 new packet type SILC_PACKET_CELL_ROUTERS.
4872 * A big security problem in the implementation discovered. The
4873 signoff of an client did not cause new channel key generation
4874 which it of course should've done. The channel keys must be
4875 always re-generated when client leaves (or signoffs) the channel.
4876 The silc_server_remove_from_channels funtion now handles
4877 the channel key re-generation.
4879 * Added `sender' argument to the silc_server_send_notify_on_channels
4880 to not to send the client provided as argument. Affected file
4881 silcd/packet_send.[ch].
4883 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4885 * Implemented OPER and SILCOPER commands into the server and
4888 * Added silc_auth_verify and silc_auth_verify_data to verify
4889 the authentication directly from the authentication payload.
4890 It supports verifying both passphrase and public key based
4891 authentication. Affected file lib/silccore/silcauth.[ch].
4893 * Added `hash' field to the SilcIDListData structure. It is the
4894 hash negotiated in the SKE protocol. Affected file is
4897 * Slight redesigning of the SilcAuthPayload handling routines.
4898 Do not send SilcPKCS but SilcPublicKey as argument.
4900 * Implemented the public key authentication support to the
4901 serverconfig. The public key is loaded from the provided path
4902 and saved as authentication data to void * pointer. Thus,
4903 changed the unsigned char *auth_data to void *auth_data;
4905 * Fixed SHUTDOWN command to send the reply before the server
4906 is shutdown. :) Affected file silcd/command.c.
4908 * Fixed fatal bug in CONNECT command. The hostname was invalid
4909 memory and server crashed. Affected file silcd/command.c.
4911 * Fixed fatal bug in CLOSE command. The server_entry became
4912 invalid but was referenced later in the command. Affected file
4915 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4917 * Fixed fatal bug in failure packet handling. Server ignored
4918 the failure and thus crashed when it came.
4922 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4924 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4925 that the command may be executed only once in (about) 2 seconds.
4926 The old SILC_CF_LAG flag is same but allows command bursts up
4927 to five before limiting.
4929 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4930 server code. Various commands now includes the CF_LAG_STRICT
4931 flag to disallow any kind of miss-use of the command.
4933 * Fixed the silc_buffer_unformat to not to allocate any data
4934 if the length of the data is zero. It used to allocate the
4935 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4937 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4939 * Changed the format of AdminConnection configuration section
4940 in the server. Added username of the admin to the format.
4941 Affected files silcd/serverconfig.[ch].
4943 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4944 to return admin configuration data by host, username and/or
4947 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Implemented WHOWAS command to the server. Added the functions:
4951 silc_server_command_whowas_parse,
4952 silc_server_command_whowas_send_reply,
4953 silc_server_command_whowas_from_client and
4954 silc_server_command_whowas_from_server
4956 * Added <Client ID> argument to the WHOWAS command reply. Updated
4957 the protocol specs accordingly.
4959 * Implemented WHOWAS command and command_reply to the client
4962 Implemented the WHOWAS printing on the user interface.
4964 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4966 * Added new argument to the WHOWAS command reply, the real name.
4967 It is an optional argument. Updated the protocol specs.
4969 * Added SilcIDCacheDestructor callback that is registered when
4970 the SilcIDCache is allocated. The callback is called when
4971 an cache entry in the ID Cache expires, or is purged from the
4972 cache. Added into lib/silccore/idcache.[ch].
4974 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4975 to destruct the client entries when the cache entry expires.
4976 Other ID Cache's in server and in the client library ignores
4979 * If the ID Cache entry's `expire' field is zero then the entry
4980 never expires. Added boolean `expire' argument to the
4981 silc_idcache_add function in the lib/silccore/idcache.[ch].
4982 If it is TRUE the default expiry value is used.
4984 * Added silc_server_free_client_data_timeout that is registered
4985 when client disconnects. By default for 5 minutes we preserve
4986 the client entry for history - for WHOWAS command.
4988 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4990 * Added support to the server to enforce that commands are not
4991 executed more than once in 2 seconds. If server receives
4992 commands from client more frequently, timeout is registered
4993 to process the commands. Affected file silcd/command.c.
4994 Added new function silc_server_command_process_timeout.
4996 * Changed NICK_NOTIFY handling in client library to check that
4997 if the client's nickname was changed, so there is no need to
4998 resolve anything from the server.
5000 * Removed error printing from the WHOIS and IDENTIFY commands.
5001 If error occurs then it is ignored silently in the client library.
5002 The application, however, may map the received error to
5003 human readable error string. The application currently maps
5004 the NO_SUCH_NICKNAME error to string.
5006 * Made the command status message public to the application. Moved
5007 them from lib/silcclient/command_reply.c to
5008 lib/silcclient/command_reply.h. The application can map the
5009 received command status to the string with the
5010 silc_client_command_status_message function.
5012 * Added check to the server to check that client's ID is same
5013 as the Source ID in the packet the client sent. They must
5016 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5018 * Added dist-bzip hook to the Makefile.am to make bzip2
5019 compressed distributions.
5021 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5023 * Server now enforces the maximum length for the nickname and
5024 the channel as protocol specification dictates. 128 bytes for
5025 nickname and 256 bytes for channel name.
5027 * Moved the WHOIS printing to the application. The client libary
5028 does not print out the WHOIS information anymore, the application
5029 must do it. Renamed silc_client_command_reply_whois_print to
5030 the silc_client_command_reply_whois_save.
5032 The client's idle time is also sent to the application now, and
5033 the idle is shown on screen.
5035 * Added silc_client_command_reply_identify_save to save the
5036 received IDENTIFY entries.
5038 * Do not check for channel private keys in message sending and
5039 reception if the channel does not have the PRIVKEY mode set.
5040 Affected file lib/silclient/client_channel.c.
5042 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5044 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5045 just surfaced after chaning the JOIN procedure.
5047 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5049 * Added silc_client_get_clients_by_list to get client entries
5050 from Client ID list, that is returned for example by JOIN
5051 and USERS command replies. The application should use this
5052 function for example when JOIN command reply is received to
5053 resolve the clients already on the channel (library does not
5054 do that anymore as USERS command reply is not used in the JOIN
5055 procedure anymore). Affected files lib/silcclient/silcapi.h and
5056 lib/silcclient/idlist.c.
5058 * JOIN command reply and USERS command reply returns now SilcBuffer
5059 pointers instead of unsigned char pointers when returning
5060 the client list and mode list.
5062 * Added <Client ID> argument to the JOIN command reply, mainly
5063 for the server to identify for which client the command was
5064 originally sent. Updated protocol specs accordingly.
5066 * Added SilcDlist private_key pointer to the SilcChannelEntry
5067 in the client to support the channel private keys. Affected
5068 file is lib/silcclient/idlist.h.
5070 * Added SilcChannelPrivateKey argument to the function
5071 silc_client_send_channel_message so that application can choose
5072 to use specific private ke if it wants to. If it is not provided,
5073 the normal channel key is used, unless private keys are set.
5074 In this case the first (key that was added first) is used
5075 as the encryption key.
5077 * Implemented the support for channel private key handling.
5078 Implemented the following functions:
5080 silc_client_add_channel_private_key,
5081 silc_client_del_channel_private_keys,
5082 silc_client_del_channel_private_key,
5083 silc_client_list_channel_private_keys and
5084 silc_client_free_channel_private_keys
5086 Affected file lib/silcclient/client_channel.c.
5088 * Added the support for the private keys in the channel message
5089 sending and encryption and in the message reception and
5090 decryption. Affected funtions are
5091 silc_client_send_channel_message and silc_client_channel_message.
5093 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5095 * Added SKE's key verify callback to the client library's
5096 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5098 * Removed the statement that server (or router) must send USERS
5099 command reply when joining to the channel so that the client
5100 knows who are on the channel. Instead, the client list and
5101 client's mode list is now sent in the JOIN command reply to the
5102 client who joined channel. This is better solution.
5104 * Added function silc_server_get_users_on_channel and function
5105 silc_server_save_users_on_channel to the silcd/server.[ch].
5107 * Removed function silc_server_command_send_users from the
5110 * Do not show topic on the client library anymore. The topic is
5111 sent in the command reply notify to the application and the
5112 application must show the topic now.
5114 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5116 * Added client searching by nickname hash into the IDENTIFY and
5117 WHOIS commands in the server as they were clearly missing from
5118 them. Affected file is silcd/command.c.
5120 * Fixed a bug in private message receiving in the client library.
5121 The remote ID was freed and it wasn't supposed, now it is
5124 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5126 * Minor fix to the channel payload; allocate the data area, as it
5127 needs to be of specific length.
5129 * If the key agreement port is zero then the operating
5130 system will define the bound port. Affected files are
5131 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5133 * Added new function silc_channel_payload_decrypt into the file
5134 lib/silccore/silcchannel.[ch].
5136 * Moved the channel message etc, check from silc_packet_decrypt
5137 to applications. The library calls now a generic
5138 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5139 when the packet is either normal or special. This was done to
5140 allow more wide range of checking that was not allowed when
5141 the code was in library. Now applications can do virtually any
5142 checks to the packet and return to the library the decision how
5143 the packet should be processed. Affected files are
5144 lib/silccore/silcpacket.[ch].
5146 Added silc_server_packet_decrypt_check to the server and
5147 silc_client_packet_decrypt_check to the client library.
5149 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5150 to send with specified source and destination information.
5152 * Channel message delivery between routers was broken after the
5153 channel key distribution was fixed earlier. The channel key
5154 was used be to distributed to other routers as well which is not
5155 allowed by the protocol. Now this is fixed and channel keys
5156 really are cell specific and the channel message delivery between
5157 routers comply with the protocol specification.
5159 * Fixed various commands in server to check also the global list
5160 for the channel entry and not just the local list. The affected
5161 file silcd/command.c.
5163 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5165 * Added assert()s to buffer formatting and unformatting routines
5166 to assert (if --enable-debug) when error occurs. Affected
5167 file: lib/silcutil/silcbuffmt.c.
5169 * Changed to auto-reconnect to check whether the remote host is
5170 router and register the re-connect timeout if it is. It used
5171 to check that whether we are normal server, but router must do
5172 auto-reconnect with another router as well. Affected file
5175 * Removed the [<key len>] option from CMODE command as the cipher
5176 name decides the key length, nowadays. See the defined ciphers
5177 from the protocol specification.
5179 * Added [<hmac>] option to the CMODE command to define the HMAC
5180 for the channel. Added SILC_CMODE_HMAC channel mode.
5182 * Added [<hmac>] option for the JOIN command so that user can
5183 select which HMAC is used to compute the MACs of the channel
5186 * Added Hmac field to the Channel Message Payload. The integrity
5187 of plaintext channel messages are now protected by computing
5188 MAC of the message and attaching the MAC to the payload. The
5189 MAC is encrypted. Now, it is clear that this causes some
5190 overhead to the size of the packet but rationale for this is that
5191 now the receiver can verify whether the channel message decrypted
5192 correctly and also when private keys are set for the channel the
5193 receiver can decrypt the packet with several keys and check from
5194 the MAC which key decrypted the message correctly.
5196 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5197 lib/silccrypt/silccipher.[ch].
5199 * Added silc_hash_len to return the digest length into the
5200 lib/silcrypt/silchash.[ch].
5202 * Rewrote parts of Silc Channel Payload interface in the
5203 lib/silccore/silcchannel.[ch]. The encode function now also
5204 encrypts the packet and parse function decrypts it.
5206 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5208 * Fixed a minor formatting bug in the SKE's key material processing.
5209 It actually might have processed the keys wrong way resulting
5212 * Redefined the mandatory HMAC algorithms and added new algorithms.
5213 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5214 and hmac-md5 truncated to 96 bits. The mandatory is now
5215 hmac-sha1-96. Rest are optional (including the one that used
5216 to be mandatory). Rationale for this is that the truncated HMAC
5217 length is sufficient from security point of view and can actually
5218 make the attack against the HMAC harder. Also, the truncated
5219 HMAC causes less overhead to the packets. See the RFC2104 for
5222 * Added new [hmac] configuration section. The SKE used to use
5223 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5224 is of course wrong. The official names that must be proposed in
5225 the SKE are the ones defined in the protocol specification
5226 (hmac-sha1-96 for example). The user can configure any hmac
5227 using any hash function configured in the [hash] section. At
5228 least, the mandatory must be configured.
5230 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5232 * Added HMAC list to the SKE proposal list. It has now both
5233 hash algorithm list and HMAC list. This makes the protocol
5234 incompatible with previous versions. The SKE now seems to work
5235 the way it is supposed to work, for the first time actually.
5237 * Defined plain Hash algorithms to the protocol specification.
5240 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5242 * Implemented support for key agreement packets into the server.
5243 Added functions silc_server_key_agreement and
5244 silc_server_send_key_agreement. Other than these functions,
5245 server has nothing to do with this packet.
5247 * Added support for private message key packets into the server.
5248 Added functions silc_server_private_message_key and
5249 silc_server_send_private_message_key.
5253 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5254 called in the protocol's final callback instead in the END
5255 protocol state. This makes a little more sense and in the same
5256 time in client we can use the same protocol routines for normal
5257 key exchange and to key agreement packet handling as well.
5259 * Added to both client's and server's KE protocol context the
5260 SilcSKEKeyMaterial pointer to save the key material. We will
5261 bring the key material to the protocol's final callback by doing
5262 this. The final callback must free the key material.
5264 * Added SKE's packet_send callback into client's KE protocol
5265 context so that the caller can choose what packet sending function
5266 is used. This way we can use different packet sending when
5267 doing normal SKE when doing key agreement packet handling (in
5268 the key agreement packet handling we do not want to encrypt
5271 * Implemented the responder side of the key agreement routines
5272 in the client. The client can now bind to specified port and
5273 accept incoming key negotiation. The key material is passed
5274 to the application after the protocol is over.
5276 * Implemented the processing of incoming Key Agreement packet
5277 in the client. Added function silc_client_key_agreement to
5280 * Implemented the intiator side of the key agreement routines
5281 in the client. The client can now initiate key agreement with
5282 another remote client. The key material is passed to the
5283 application after the protocol is over.
5285 * Created client_keyagr.c to include all the key agreement
5288 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5289 SILC_TASK_CALLBACK except that it is not static.
5291 * Created client_notify.c and moved the Notify packet handling
5292 from the client.[ch] into that file.
5294 * Created client_prvmsg.c and moved all private message and
5295 private message key routines from the client.[ch] into that file.
5297 * Create client_channel.c and moved all channel message and
5298 channel private key routines from the client.[ch] into that file.
5300 * Changed silc_client_get_client_by_id_resolve to resolve with
5301 WHOIS command instead of IDENTIFY command, in the file
5302 lib/silclient/idlist.c.
5304 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5306 * Implemented the SKE's responder side to the Client library.
5308 * When FAILURE is received to the protocol do not trust it
5309 blindly. Register a timeout to wait whether the remote closes
5310 the connection as it should do it, only after that process the
5311 actual failure. This was changed to both client and server.
5313 * Added client_internal.h to include some of the structures
5314 there instead of client.h in lib/silcclient/.
5316 * Added function silc_task_unregister_by_callback to unregister
5317 timeouts by the callback function.
5319 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5321 * Some "Incomplete WHOIS info" errors has been appearing on the
5322 log files. Took away the entry->userinfo check from WHOIS
5323 reply sending. The entry->userinfo is now " " if client did not
5324 provide one. I thought this was fixed earlier but something
5325 is wrong still. Let's see if the error still appears.
5327 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5329 * Fixed a minor bug in the login when the channel key is
5330 re-generated in the server. It used to generate the key in
5331 wrong order and thus caused problems in the channel traffic.
5333 * Fixed a minor bug in channel key distsribution after
5334 KICK command. The key was not sent to the router even though
5337 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * Added silc_ske_process_key_material_data as generic routine
5340 to process any key material as the SILC protocol dictates. The
5341 function is used by the actual SKE library but can be used by
5342 applications as well. This relates to the private message keys
5343 and the channel private keys since they must be processed the
5344 same way the normal SILC session keys. The protocol dictates
5345 this. Affected files: lib/silcske/silcske.[ch].
5347 Added also silc_ske_free_key_material to free the
5348 SilcSKEKeyMaterial structure.
5350 * Defined silc_cipher_set_key function to set the key for
5351 cipher without using the object's method function. The affected
5352 files: lib/silccrypt/silccipher.[ch].
5354 * Implemented silc silc_client_add_private_message_key,
5355 silc_client_add_private_message_key_ske,
5356 silc_client_del_private_message_key,
5357 silc_client_list_private_message_keys and
5358 silc_client_free_private_message_keys functions in the
5361 Added functions silc_client_send_private_message_key to send
5362 the Private Message Key payload and silc_client_private_message_key
5363 to handle incoming Private Message Key payload.
5365 * Added Cipher field to the Private Message Key payload to set
5366 the cipher to be used. If ignored, the default cipher defined
5367 in the SILC protocol (aes-256-cbc) is used.
5369 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5371 * Removed lib/silcclient/ops.h file.
5373 Redefined parts of the SILC Client Library API. Created new
5374 file silcapi.h that deprecates the ops.h file and defines the
5375 published Client Library API. Defined also private message key
5376 API and channel private key API into the file.
5378 This is the file that the application must include from the
5379 SILC Client Library. Other files need not be included by
5380 the application anymore.
5382 * Added new key_agreement client operation callback and also
5383 defined the Key Agreement library API for the application.
5385 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5387 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5388 is used by clients to request key negotiation between another
5389 client in the SILC network. If the negotiation is started it
5390 is performed using the SKE protocol. The result of the
5391 negotiation, the secret key material, can be used for example
5392 as private message key.
5394 Implemented the Key Agreement payload into the files
5395 lib/silccore/silauth.[ch].
5397 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5399 * Redefined ciphers for the SILC protocol. Added some new ciphers
5400 and defined the key lengths for the algorithms. Changed the
5401 code accordingly. The default key length is now 256 bits.
5403 * Fixed SKE key distribution function silc_ske_process_key_material
5404 when the key length is more than 128 bits. The default key
5405 length in SILC is now 256 bits.
5407 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5408 to indicate unsupported algorithm.
5410 * Renamed rijndael.c to aes.c and all functions as well.
5412 * Fixed a long standing channel key setting bug in client library.
5413 Weird that it has never surfaced before.
5415 * Fixed bug in channel deletion. If the entire channel is removed
5416 then it must also delete the references of the channel entry
5417 from the client's channel list as the client's channel entry and
5418 the channel's client entry share same memory.
5420 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5422 * Implemented CONNECT and SHUTDOWN commands in the client.
5424 * Implemented CLOSE command to the client.
5426 * Added the function silc_idlist_find_server_by_name into the
5427 files silcd/idlist.[ch].
5429 Added the function silc_idlist_find_server_by_conn into the
5430 files silcd/idlist.[ch].
5432 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5434 * DIE command was renamed to SHUTDOWN. Updated the both code
5437 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5438 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5440 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5443 * Added function silc_server_create_connection function to create
5444 connection to remote router. My server implementation actually
5445 does not allow router to connect to normal server (it expects
5446 that normal server always initiates the connection to the router)
5447 so the CONNECT command is only good for connecting to another
5450 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5452 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5453 or some other client was kicked from the channel.
5455 Implemented the handling of the notify type to both client
5458 Implemented silc_server_send_notify_kicked to send the KICKED
5459 notify. It is used to send it to the server's primary router.
5461 * Implemented the KICK command into server and client.
5463 * Added `query' argument to the silc_idlist_get_client function
5464 to indicate whether to query the client from server or not if
5467 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5468 to indicate that the client is not channel founder.
5472 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5474 * Removed the rng context from SilcPacketContext structure and
5475 changed that the packet routine uses the Global RNG API.
5477 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5479 * Added support for quit message that client can "leave" on the
5480 channel when it quits the SILC. It is ditributed inside the
5481 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5483 Added silc_server_free_client_data that will take the
5484 signoff message as argument.
5486 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5488 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5490 * Updated parts of the protocol specification to keep it up
5493 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5495 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5496 payloads in one packet.
5498 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5499 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5500 use now the new List flag.
5502 * Also deprecated the following packet types: REPLACE_ID,
5503 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5505 * Added list support for Notify packet in server.
5507 * Added silc_server_send_notify_channel_change to send the
5508 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5509 the silc_server_send_replace_id.
5511 * Added silc_server_send_notify_nick_change to send the
5512 NICK_CHANGE notify type. Deprecates the function
5513 silc_server_send_replace_id.
5515 * Added silc_server_send_notify_join to send the JOIN notify type.
5516 Deprecates the function silc_server_send_new_channel_user.
5518 * Added silc_server_send_notify_leave to send LEAVE notify type.
5519 Deprecates the function silc_server_send_remove_channel_user.
5521 * Added silc_server_send_notify_cmode and
5522 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5523 types. Deprecates the silc_server_send_set_mode function.
5525 * Added SERVER_SIGNOFF notify type to indicate that server has
5526 quit. This means that all clients on the channel from that
5527 server will drop. This can be also used when netsplit happens.
5529 Deprecated REMOVE_ID packet type since it is not needed anymore
5532 Added silc_server_send_notify_server_signoff to send the
5533 SERVER_SIGNOFF notify type. Deprecates the function
5534 silc_server_send_remove_id.
5536 Added also silc_server_send_notify_signoff to send the
5537 SIGNOFF notify type.
5539 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5540 SILC protocol from this day on. Changed the protocol
5541 specification as well.
5543 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5544 notify type. It is used between routers to notify about
5545 topic changes on a channel.
5547 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5550 * Partly updated the protocol specification to comply with the
5551 changes now made. It is still though a bit outdated.
5553 * The JOIN notify type now takes one extra argument <Channel ID>.
5554 The packet used to be destined to the channel but now the
5555 JOIN type may be sent as list thus it is impossible to
5556 destine it to any specific channel. By adding this argument
5557 it is again possible.
5559 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5561 * Added CREDITS file. The CHANGES and CREDITS file will appear
5562 in the distribution as well.
5564 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5567 types in the server's silcd/packet_receive.c.
5569 * Implemented CMODE and CUMODE to work in router environment.
5571 * Fixed minor encoding and decoding buglet from the
5572 lib/silccore/silcmode.c.
5574 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5577 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5579 * Changed all SilcConfigServer* and silc_config_server* to
5580 SilcServerConfig* and silc_server_config*, respectively.
5583 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Associated the ID (client or server ID) to the Authentication
5586 Payload to avoid any possibility of forging. Updated the
5587 protocol specification and the code accordingly.
5589 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5591 * The RSA key length is now save to the RsaKey context in the
5592 key generation process in lib/silccrypt/rsa.c. The key length
5593 is now used to figure out the maximum size of the block allowed
5594 to be encrypted/signed.
5596 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5597 is equivalent to the silc_mp_mp2bin but does not allocate any
5600 * Changed silc_mp_mp2bin API to take length argument. If it is
5601 non-zero then the buffer is allocated that large. If zero, then
5602 the size is approximated using silc_mp_sizeinbase, which however
5605 * Created Global RNG API which is global RNG that application can
5606 initialize. After initializing, any routine anywhere in the
5607 code (including library) can use RNG without allocating a new
5608 RNG object. This was done to allow this sort of use of the
5609 RNG in code that has no chance to allocate RNG object. All
5610 applications currently allocate this and many routines in the
5611 library use this. Affected file lib/silccrypt/silcrng.[ch].
5613 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5614 it to use the Global RNG API.
5616 * Defined Authentication Payload into protocol specification that
5617 is used during SILC session to authenticate entities. It is
5618 used for example by client to authenticate itself to the server
5619 to obtain server operator privileges.
5621 Implemented this payload into the lib/silccore/silcauth.[ch].
5622 Implemented also routines for public key based authentication
5623 as the new protocol specification dictates.
5625 Moved definitions of different authentication methods from
5626 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5628 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5629 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5630 silc_pkcs_verify_with_hash functions into the file
5631 lib/silccrypt/silcpkcs.[ch].
5633 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5635 * The client entry's userinfo pointer must be always valid.
5636 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5637 will fail since it requires the userinfo. Now, the userinfo
5638 is allocated as "" if actual userinfo does not exist. Actually,
5639 it must exist and it is totally Ok to drop client connections
5640 that does not announce the userinfo. However, we will make
5641 this workaround for now.
5643 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5644 to return the remote port by socket.
5646 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5648 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5649 SILC_SERVER_PENDING_EXEC and added an new macro
5650 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5651 data or when error occurs while processing the pending command.
5653 Added new argument `destructor' into silc_server_command_pending
5654 and to the SilcServerCommandPending object. This destructor is
5655 now called after calling the pending callback or if error occurs
5656 immediately. If error occurs the actual pending callback won't
5657 be called at all - only the destructor. The destructor may be
5658 NULL if destructor is not needed.
5660 All this applies for client library code as well. Similar
5661 changes were made there as well for the pending commands.
5663 In the client, the application must now allocate the
5664 SilcClientCommandContext with the silc_client_command_alloc
5667 * Added reference counter to the SilcServerCommandContext. Added
5668 function silc_server_command_alloc and silc_server_command_dup
5671 Same type of functions added to the client library for the same
5674 * Removed the cmd_ident from IDListData away since it is now
5675 global for all connections. It is the command identifier used
5676 in command sending and with pending commands. The affected file
5679 * Added reference counter to the SilcSocketConnection objecet to
5680 indicate the usage count of the object. The object won't be
5681 freed untill the reference counter hits zero. Currently only
5682 server uses this, and client ignores it. The client must be
5683 set to use this too later. The affected files are
5684 lib/silccore/silcsockconn.[ch]. Added also the function
5685 silc_socket_dup to increase the reference counter.
5687 This was mainly added because it is possible that the socket
5688 is removed underneath of pending command or other async
5689 operation. Now it won't be free'd and proper DISCONNECTING
5690 flags, etc. can be set to avoid sending data to connection that
5691 is not valid anymore.
5693 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5694 the connection. After that it sets SILC_SET_DISCONNECTED.
5695 It is, however, possible that the socket data is not still freed.
5696 The silc_server_packet_process now checks that data is not
5697 read or written to connection that is DISCONNECTED. The socket
5698 get's freed when the reference counter hits zero.
5700 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5702 * Changed the client operation API: channel_message operation's
5703 `sender' is now the client entry of the sender, not the nickname
5704 and the `channel' is the channel entry, not the channel name.
5706 In the private_message operation the `sender' is now also the
5707 client entry of the sender not the nickname.
5709 Affected file is lib/silcclient/ops.h and all applications
5710 using the client operations.
5712 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5714 * Moved the calling of ops->connect() from connect_to_server_final
5715 into receive_new_id functin since that is the point when the
5716 client is actually allowed to send traffic to network. The
5717 affected file is lib/silcclient/client.c.
5719 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5721 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5722 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5723 (if needs broadcasting) instead of broadcasting the packets one
5724 by one which would make a burst in the network traffic.
5726 * Added `broadcast' argument to the functions in silcd/server.[ch]
5727 silc_server_create_new_channel[_with_id] to indicate whether
5728 to send New Channel packet to primary router.
5730 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5732 * Added new function into the silcd/server.[ch] files:
5733 silc_server_create_new_channel_with_id to create new channel with
5734 already existing Channel ID.
5736 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5737 lib/silccore/silcpacket.h. This packet is used t send list of
5738 Set Mode payloads inside one packet. Server uses this to set
5739 the modes for the channels and clients on those channels, that it
5740 announced to the router when it connected to it. The protocol
5741 specification has been updated accordingly.
5743 * The silc_server_new_channel did not handle the packet coming
5744 from normal server as it normally does not send that. However,
5745 when it announces its channels it does send it. Implemented
5746 the support for that.
5748 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5749 into the file lib/silccore/id.h.
5751 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5753 * Fixed memory leaks in the functions silc_idlist_del_client,
5754 silc_idlist_del_channel and silc_idlist_del_server in the file
5755 silcd/idlist.c. All of those leaked like a sieve.
5757 * Fixed some small memory leaks in the client's function
5758 silc_client_notify_by_server.
5760 * Added functions into silcd/server.c: silc_server_announce_clients,
5761 silc_server_announce_channels and silc_server_announce_server.
5762 These functions are used by normal and router server to announce
5763 to its primary router about clients, channels and servers (when
5764 router) that we own. This is done after we've connected to the
5767 These functions effectively implements the following packet types:
5768 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5769 and SILC_PACKET_NEW_ID_LIST.
5771 * Added new functions into the silcd/packet_receive.[ch]:
5772 silc_server_new_id_list, silc_server_new_channel_list and
5773 silc_server_new_channel_user_list to handle the incoming
5774 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5776 * Added support of changing Channel ID in the function
5777 silc_server_replace_id. If the server that announces a channel
5778 to the router already exists in the router (with same name but
5779 with different Channel ID), router is responsible to send
5780 Replace ID packet to the server and force the server to change
5781 the Channel ID to the one router has.
5783 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5784 client that the Channel ID has been changed by the router. The
5785 normal server sends this to the client. Client must start using
5786 the new Channel ID as the channel's ID.
5788 Implemented handling of this new type into lib/silcclient/client.c
5789 into the function silc_client_notify_by_server.
5791 * Added new function silc_idlist_replace_channel_id into the files
5792 silcd/idlist.[ch] to replace the Channel ID.
5794 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5796 * Call silc_server_command_identify_check always when processing
5797 the IDENTIFY command in silcd/command.c
5799 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5801 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5802 send keepalive packets. The packet can be sent by clients,
5803 servers and routers.
5805 Added function silc_socket_set_heartbeat into the file
5806 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5807 If not set, the heartbeat is not performed. The actual
5808 heartbeat is implemented in the low level socket connection
5809 library. However, application is responsible of actually
5812 Added silc_server_send_heartbeat to send the actual heartbeat
5813 packet into silcd/packet_send.[ch]. Server now performs
5814 keepalive with all connections.
5816 * Added silc_task_get_first function into lib/silcutil/silctask.c
5817 to return the timeout task with shortest timeout. There was a bug
5818 in task unregistration that caused problems. TODO has been
5819 updated to include that task system must be rewritten.
5821 * The client library will now resolve the client information when
5822 receiving JOIN notify from server for client that we know but
5823 have incomplete information.
5825 * Rewrote parts of silc_server_remove_from_channels and
5826 silc_server_remove_from_one_channel as they did not remove the
5827 channel in some circumstances even though they should've.
5829 * Encryption problem encountered in server:
5831 The LEAVE command used to send the Channel Key packet to the
5832 router immediately after generating it. However, the code
5833 had earlier sent Remove Channel user packet but not immediately,
5834 ie. it was put to queue. The order of packets in the router
5835 was that Channel Key packet was first and Remove Channel User
5836 packet was second, even though they were encrypted in the
5837 reverse order. For this reason, MAC check failed. Now, this
5838 is fixed by not sending the Channel Key packet immediately but
5839 putting it to queue. However, this is more fundamental problem:
5840 packets that are in queue should actually not be encrypted
5841 because packets that are sent immediately gets encrypted
5842 actually with wrong IV (and thus MAC check fails). So, packets
5843 that are in queue should be encrypted when they are sent to
5844 the wire and not when they put to the queue.
5846 However, the problem is that the current system has not been
5847 designed to work that way. Instead, the packet is encrypted
5848 as soon as possible and left to the queue. The queue is then
5849 just purged into wire. There won't be any fixes for this
5850 any time soon. So, the current semantic for packet sending
5853 o If you send packet to remote host and do not force the send
5854 (the packet will be in queue) then all subsequent packets to the
5855 same remote host must also be put to the queue. Only after the
5856 queue has been purged is it safe again to force the packet
5859 o If you send all packets immediately then it safe to send
5860 any of subsequent packets through the queue, however, after
5861 the first packet is put to queue then any subsequent packets
5862 must also be put to the queue.
5864 Follow these rules and everything works fine.
5866 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5868 * Added new function silc_server_remove_clients_by_server to
5869 remove all client entries from ID list when the server connection
5870 is lost. In this case it is also important to invalidate all
5871 client entires as they hold the invalid server entry. This
5872 fixes fatal bug when server has lost connection and will reconnect
5875 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5877 * Made some sanity checks to silc_server_daemonise like to check
5878 whether the requested user and group actually exists.
5880 * Added sanity check to SKE's silc_ske_responder_finish to check
5881 that the public and private key actually is valid.
5883 * Invalidate the client's nickname when receiving Replace ID
5884 packet and the Client ID is being replaced. This means that the
5885 server will query the nickname if someone needs it (client)
5888 * Sort the ID Cache in client library when the ID Cache data
5889 has changed (needs sorting).
5891 * Do not allow for SILC client to create several connections to
5892 several servers. The client does not support windows right now
5893 and generating multiple connections causes weird behaviour.
5895 Irssi-silc client does support windows and can handle several
5896 connections without problems, see: www.irssi.org and SILC plugin.
5898 * Fixed some places where client was added to the IDList. The
5899 rule of thumb is following (in order to get everything right):
5900 If the client is directly connected local client then the
5901 `connection' argument must be set and `router' argument must be
5902 NULL to silc_idlist_add_client function. If the client is not
5903 directly connected client then the `router' argument must
5904 bet set and the `connection' argument must be NULL to the
5905 silc_idlist_add_client function.
5907 * The funtion silc_server_packet_send_local_channel actually did
5908 not check whether the client was locally connected or not. It
5909 does that now. Fixed a bug related to LEAVE command.
5911 * Fixed Remove Channel User payload parsing bug in server's
5912 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5914 * The server's silc_server_save_channel_key now checks also the
5915 global ID list for the channel as it might not be in the local
5916 list. Fixed a bug related to LEAVE command.
5918 * Is this the end of the [<unknown>] buglet that has been lurking
5919 around for a long time? A little for loop fix in server's
5920 silc_server_command_whois_parse that is used by both IDENTIFY
5921 and WHOIS command. At least, this was a clear bug and a cause
5922 of one type of [<unknown>] buglet.
5924 * WHOIS and IDENTIFY commands call the function
5925 silc_server_command_[whois/identify]_check function even if
5926 we are not router server.
5928 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Added --with-gmp configuration option. If set the GMP
5931 is always compiled in the SILC source tree. If not set then
5932 it is checked whether the system has the GMP3 installed. If
5933 it has then the GMP won't be compiled (the system's headers
5934 and library is used), if it doesn't have it then the GMP is
5935 compiled in the SILC source tree.
5937 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5939 * Changed RSA private exponent generation to what PKCS #1
5940 suggests. We try to find the smallest possible d by doing
5941 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5942 not security fix but optimization.
5944 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5946 * Added new config entry [Identity] to fork the server and run
5947 it as specific user and group. A patch from Bostik.
5949 * Imported Dotconf configuration library into lib/dotconf.
5950 This will be used to create the SILC configuration files later.
5951 It will appear in the distsribution after this commit.
5953 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5955 * A big code auditing weekend happening. Auditing code for
5956 obvious mistakes, bugs and errors. Also, removing any code
5959 Removed files for being obsolete:
5961 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5962 inline in the file lib/silcutil/silcbuffer.h)
5964 o lib/silcutil/silcbufutil.c (the header has inline versions)
5966 Changed code to fix possible error conditions:
5968 o The buffer formatting routines now check that the destination
5969 buffer really has enough space to add the data. This applies for
5970 both buffer formatting and unformatting
5971 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5972 unformatting was changed to accomodate following rules:
5973 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5974 sent to the function while XXX_*STRING will not allocate or copy
5975 the data into the buffer. Instead it sets the pointer from the
5976 buffer into the pointer sent as argument (XXX_*STRING used to
5977 require that the pointer must be allocated already). This change
5978 makes this whole thing a bit more consistent and more optimized
5979 (note that the data returned in the unformatting with XXX_*STRING
5980 must not be freed now). The routines return now -1 on error.
5982 o Tried to find all code that use buffer_format and buffer_unformat
5983 and added return value checking to prevent formatting and
5984 especially unformatting errors and possible subsequent fatal
5987 o Changed ske->x and ske->KEY to mallocated pointers in
5988 lib/silcske/silcske.h. Fixed possible data and memory leak.
5990 o Added return value checking to all *_parse* functions. Fixed
5991 many memory leaks as well.
5993 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5994 so that buffer overflows would not happen. All code now also
5995 checks the return value as it can fail.
5997 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5999 * Added reconnection support to server if the normal server looses
6000 its connection to the router (for example if router is rebooted).
6001 The server performs normal reconnection strategy implemented
6002 to the server. Affected file silcd/server.c.
6004 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6006 * Added new packet type SILC_PACKET_SET_MODE that is used to
6007 distribute the information about changed modes (for clients,
6008 channels and clients channel modes) to all routers in the
6009 network. Updated the protocol specification accordingly.
6011 Added functions into silcd/packet_send.c and
6012 silcd/packet_receive.c: silc_server_send_set_mode,
6013 silc_server_set_mode.
6015 Added new files silcmode.[ch] into lib/silccore that implements
6016 the encoding and decoding of Set Mode Payload. Added new type
6017 SilcSetModePayload. Moved the definitions of different modes
6018 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6020 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6022 * Oops, a little mistake in server's connection authentication
6023 protocol. The protocol is not ended with FAILURE but with
6024 SUCCESS if the authentication is Ok. :) Affected file is
6027 * Implemented NICK_CHANGE notify handling in server in the file
6028 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6029 the local clients on the channel. After the changing nickname
6030 in router environment snhould work and the [<unknown>] nickname
6031 should appear no more.
6033 The silc_server_replace_id function that receives the Replace ID
6034 payload now sends the NICK_CHANGE notify type also in the file
6035 silcd/packet_receive.c
6037 * Changed WHOIS and IDENTIFY command to support the maximum amount
6038 of arguments defined in protocol specs (3328 arguments). This
6039 fixed a bug that caused problems when there were more than three
6042 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6044 * Added extra parameter, command identifier, to the
6045 silc_client_send_command so that explicit command identifier
6048 Changed that ID list routines uses specific command identifier
6049 when sending WHOIS/IDENTIFY requests to the server so that they
6050 can be identified when the reply comes back.
6052 Affected files lib/silcclient/command.[ch],
6053 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6055 * Added `sender' argument to silc_server_packet_send_to_channel
6056 to indicaet the sender who originally sent the packet to us
6057 that we are now re-sending. Ignored if NULL. Affected file
6058 silcd/packet_send.[ch].
6060 * Added some server statistics support in silcd/server_internal.h
6061 SilcServerStatistics structure and around the server code. Also
6062 send some nice statistics information when client is connecting
6065 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6067 * Fixed channel ID decoding in server's JOIN command reply in
6068 silcd/command_reply.c
6070 * Fixed braodcasting of replace ID payload to not to send it if
6071 we are standalone server in silcd/packet_receive.c.
6073 * Fixed all channel message sending routines to not to send
6074 packets to clients that has router set, since they are routed
6075 separately in the same function earlier. Affects file
6076 silcd/packet_send.c and all channel packet sending functions.
6078 * In USERS reply, res_argv[i] are not allocated, the table
6079 is allocated. Thus changed that free the table, not its
6082 * In server's whois_check and identify_check if the client is
6083 locally connected do not send any WHOIS commands - they are not
6086 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6088 * Fixed some minor bugs in client when sending WHOIS command. The
6089 arguments was in wrong order.
6091 * Removed statis function add_to_channel from server in
6092 silcd/command.c that was previously used with the joining but
6095 * Tested USERS command in router environment successfully with two
6096 routers, two servers and two clients.
6098 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6100 * Reorganized the USERS command and command reply in client library
6101 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6102 When the command is given by user we register a pending command
6103 callback that will reprocess the command after the reply has been
6104 received from the server. When reprocessing the packet we then
6105 display the information. Thus, the USERS information is displayed
6106 now in the command callback instead of in the command reply
6107 callback. The processing of the command is same as previously
6108 when server has sent the command reply in the JOINing process.
6110 * Added to USERS command in silcd/command_reply.c to join the client,
6111 we didn't use to know about, to the channel after we've created
6112 a client entry for it. Also, for clienet we did know already still
6113 check whether it is on the channel or not and add it if not.
6115 * Removed silc_server_command_join_notify as the function and its
6118 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6120 * Changed the client's pending command handling to the same as the
6121 server's pending command handling. It is also now possible to
6122 execute command reply functions from other command reply
6123 function as the function callbacks for commands and command
6124 replies are one and same. The pending commands are not static
6125 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6126 in client connection context. Thus, pending commands are server
6127 connection specific as it is convenient.
6129 Changed the function silc_client_command_pending and
6130 silc_client_command_pending_del and added new function
6131 silc_client_command_pending_check. Removed the
6132 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6135 * Added cmd_ident, current command identifier, to the client
6136 connection context in lib/silcclient/client.h to keep track on
6137 command identifiers used in command sending. Client's command reply
6138 function handling now supports the mandatory command identifiers.
6140 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6141 funtions in client to fully support pending command callbacks.
6143 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6144 as one of the arguments to the application in the command reply
6147 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6148 before first releasing SILC but came back. Now it is removed again
6149 and should come back nomore. The FORWARDED flag was used only
6150 by the JOINing procedure by forwarding the command packet to router.
6151 Now, the JOINing procedure has been changed to more generic (due
6152 to various router environment issues) and FORWARDED is not needed
6153 anymore for anything. The protocol specification is yet to be
6156 Now, removed silc_server_packet_forward from server and the flag
6157 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6159 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6161 * Renamed NAMES command to USERS command. The NAMES was named that
6162 due to historical reasons. Now it is renamed. Also, rewrote
6163 parts of the USERS command. The nickname list is not sent anymore
6164 by the server. Only Client ID and mode lists are sent in the USERS
6165 command. Changed this also to the protocol specification.
6167 The client now resolves the names and stuff after it receives
6168 the USERS list from the server when joining to the channel.
6170 * WHOIS and IDENTIFY commands has been changed to support multiple
6171 Client ID's per command. One can now search for multiple users
6172 in the network by sending only one WHOIS or IDENTIFY command.
6173 Changed the code and the protocol specifications.
6175 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6176 uses silc_server_command_whois_parse to parse the request. */
6178 * If normal server, do not parse the WHOIS and IDENTIFY requests
6179 before sending it to the router. Saves some time.
6181 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6183 * Fixed JOIN command on client library. Wrong number of arguments
6184 used to crash the client.
6186 * Added silc_server_channel_has_global function to check whether
6187 channel has global users or not.
6189 * Added silc_server_channel_has_local function to check whether channel
6190 has locally connected clients on the channel.
6192 * The silc_server_remove_from_one_channel now checks whether the
6193 channel has global users or not after given client was removed from
6194 the channel. It also checks whether the channel has local clients
6195 on the channel anymore. If it does not have then the channel entry
6196 is removed as it is not needed anymore.
6198 * The silc_server_notify now checks on JOIN notify whether the joining
6199 client is one of locally connected or global. If it is global then
6200 the channel has now global users on the channel and that is marked
6201 to the channel entry. Also, it now saves the global client to
6202 global list who is joining and JOINs it to the channel. This is
6203 for normal server, that is.
6205 Changed silc_server_send_notify_on_channel,
6206 silc_server_packet_relay_to_channel and
6207 silc_server_packet_send_to_channel check if we are normal server
6208 and client has router set (ie. global client) do not send the
6209 message to that client, as it is already routed to our router.
6211 * Implemented LEAVE notify type handling in silc_server_notify
6214 * Tested LEAVE command in router environment successfully. Tested
6215 with two routers, two servers and two clients.
6219 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6221 * Implemented SIGNOFF notify type handling in silc_server_notify
6224 * silc_server_remove_id now removes the client entry from all channels
6225 it has joined and thusly sends SIGNOFF notify type.
6227 * Rewrote the NAMES list generation in server by removing two excess
6228 loops. The lists are created now inside one loop.
6230 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6232 * silc_server_remove_channel_user checks now also global list
6233 for channel and client.
6235 * silc_server_new_channel_user checks now both local and global
6236 list for channel and client. Fixed a bug in client id decoding.
6237 Used to decode wrong buffer.
6239 * silc_server_channel_message checks now both local and global
6240 list for channel entry.
6242 * Tested channel joining (hence JOIN) in router environment
6243 successfully. Tested with two routers, two servers and two
6246 * Tested channel message sending in router environment successfully.
6248 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6250 * Added silc_server_save_channel_key into server.[ch] to save the
6251 received channel key in Channel Key payload processing. It is
6252 also used in JOIN command reply handling.
6254 Equivalent function silc_client_save_channel_key added into
6255 client.[ch] into client library.
6257 * Changed JOIN command reply to send information whether the channel
6258 was created or not (is existing already) and the channel key
6259 payload. Changed protocol specs accordingly.
6261 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6262 the request was sent by ID and not by nickname. Crashed on
6265 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6267 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6268 now correctly save the received data.
6270 * silc_server_free_sock_user_data now notifies routers in the
6271 network about entities leaving the network.
6273 At the same time implemented functions silc_server_remove_id
6274 and silc_server_send_remove_id to receive and send REMOVE_ID
6275 packets. The packet is used to notify routers in the network
6276 about leaving entities. The ID removed will become invalid in
6279 * Added function silc_idlist_del_server into server. Removes and
6280 free's server entry from ID list.
6282 * silc_server_private_message function now checks, if we are router,
6283 that the destination ID really is valid ID, naturally.
6285 * In router when NEW_ID packet is received (for new client) the
6286 hash of the Client ID is saved in the ID Cache but the
6287 client->nickname is set to NULL, instead of putting the hash
6290 IDENTIFY command now also checks that client->nickname must be
6291 valid. If it is not if will request the data from the server who
6292 owns the client. Added new function
6293 silc_server_command_identify_check.
6295 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6296 to set the command to already allocated Command Payload.
6298 * Tested private message sending in router environment with two
6299 routers, two servers and two clients. Fixed minor bugs and now
6302 * Fixed segfault from client's NAMES command. Used to crash if
6305 * Forwarded packets must not be routed even if it is not destined
6306 to the receiver. Changed server code comply with this.
6308 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6310 * Added `require_reverse_mapping' boolean value to ServerParams
6311 structure. If TRUE (not default) the server will require that
6312 the connecting host has fully qualified domain name.
6314 If the reverse mapping is not required and hostname could not be
6315 found the IP address is used as hostname.
6317 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6319 * Implemented version string checking to both client and server.
6320 The check is incomplete currently due to the abnormal version
6321 strings used in development version of SILC.
6323 * Changed all command functions in server to use the new
6326 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6328 * Changed char *data to unsigned char *data in ID Cache system to
6329 support binary data as ID Cache data. Changed code to support
6330 binary data in lib/silccore/idcache.c.
6332 * Renamed silc_server_packet_relay_command_reply to
6333 silc_server_command_reply as it is normal packet receiving
6334 function. Rewrote the function to accept command replys for
6335 servers and not only for clients.
6337 * Mark remote router always as registered server if we are connecting
6338 to it. Otherwise, commands sent by the router to us are ignored.
6340 * All ID List find routines now returns the ID Cache Entry pointer
6341 as well if requested.
6343 * WHOIS command works now in router environment, tested with two
6344 routers, two servers and two clients.
6346 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6347 in router environment (as it is almost equivalent to WHOIS) but
6348 hasn't been tested thoroughly. Added new functions:
6350 silc_server_command_identify_parse
6351 silc_server_command_identify_send_reply
6352 silc_server_command_identify_from_client
6353 silc_server_command_identify_from_server
6355 * Disabled route cache adding because adding two different ID's with
6356 same IP replaces the old cache entry thus giving wrong route.
6357 The entry->router->connection is always the fastest route anyway
6358 so route cache may not be needed. Of course, new routes maybe
6359 established after receiving the ID when the entry->router->connection
6360 might not be anymore the most optimal.
6362 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6364 * Add route cache for received ID for fast routing.
6366 * Added silc_server_packet_route to route received packet on router
6367 that is not destined to us.
6369 * Renamed silc_server_get_route to silc_server_route_get.
6371 * Added id_string and id_string_len fields into SilcServer to
6372 include encoded ServerID for fast comparing without excess
6373 encoding of the ID's.
6375 * Cleaned up WHOIS command on server side. Added following static
6378 silc_server_command_whois_parse
6379 silc_server_command_whois_check
6380 silc_server_command_whois_send_reply
6381 silc_server_command_whois_from_client
6382 silc_server_command_whois_from_server
6384 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6385 arguments in command replies. All command functions should be
6386 updated to use this macro.
6388 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6390 * Minor typo fixes on command reply handling on server.
6392 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6394 * Added silc_server_command_add_to_channel internal routine to add
6395 the client to the channel after router has created the channel and
6396 sent command reply to the server.
6398 * Added generic silc_server_send_command to send any command from
6401 * Use static buffer with ID rendering instead of duplicating data.
6403 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6405 * Fixed a channel user mode bug when joining to a channel server gave
6406 everybody channel founder rights, oops.
6408 * We mark ourselves as the router of the incoming server connection
6409 if we are router ourselves. This way we can check in some packet
6410 sending functions whether it is locally connected server. For
6411 incoming router connections we put NULL.
6413 * For router sending packets locally means now always sending the
6414 packet cell wide; to local clients and local servers. For normal
6415 server sending packet locally means sending it to only local
6418 * Fixed the JOIN command to really work in router environment. If the
6419 channel is created it is always created by the router. Router is
6420 also responsible of making the initial joining to the channel,
6421 sending JOIN notify to the sending server and distributing
6422 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6423 does not exist server doesn't do anything else but forward the
6424 command to the router which performs everything.
6426 * Added silc_server_send_channel_key function to send the Channel Key
6429 * Added silc_server_create_channel_key to create new channel key. The
6430 channel key is now re-generated everytime someone joins or leaves
6431 a channel, as protocol dictates. Note: channel->key_len is the
6434 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6436 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6437 packet_receive.[ch] to separate packet sending and receiving
6438 routines. The server.[ch] now includes everything else including
6439 actual packet processing (writing and reading data) and other
6442 Renamed silc_server_private_message_send_internal to
6443 silc_server_send_private_message. The routine is still though
6444 used only to relay private messages as server does not send
6445 private messages itself.
6447 Renamed silc_server_new_channel to silc_server_create_new_channel
6448 and added new function sicl_server_new_channel that handles the
6449 incoming New Channel packet. Added also new sending function
6450 silc_server_send_new_channel to send New Channel Payload.
6452 * Added new function silc_server_notify to process incoming notify
6453 packet to the server/router. Server may then relay the notify
6454 to clients if needed.
6456 * Added new function silc_server_new_channel_user to process incoming
6457 New Channel User packet. Router will redistribute the packet and
6458 send JOIN notify to its local clients and locally connected servers
6459 if needed. Normal server will send JOIN notify to its local client
6460 on same channel when received this packet. Added also corresponding
6461 sending function silc_server_send_new_channel_user to sent the
6464 * Added boolean route argument to send_notif_to_channel and
6465 packet_send_to_channel functions to attempt to route the packet
6466 if it is TRUE and send only locally if it is FALSE.
6468 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6470 * silc_server_replace_id now broadcasts the received replace ID
6471 packet if it is not broadcast packet already. The router must
6472 broadcast to inform other routers about changed ID.
6474 * Added backpointer to server's router into SilcServer context in
6475 silcd/server_internal.h.
6477 * Fixed silc_server_packet_broadcast to send correct broadcast
6480 * The channel key is now distributed to the local client as soon
6481 as it is received from the router (in router environment) so that
6482 no other packet may be sent for the channel until client has
6485 * silc_server_remove_channel_user now broadcasts the received
6486 Remove Channel User packet if it is not broadcast packet already.
6487 The router must broadcast to inform other routers about removed
6490 * Added users field into SilcPacketContext that is a reference count
6491 of the context. One can increase the reference count by calling
6492 silc_packet_context_dup which is now changed to just increase the
6493 reference count instead of duplicating the data. The reference
6494 count is decresed by calling silc_packet_context_free that will
6495 free the data after the reference count hits zero.
6497 For now on the packet context and everything allocated into it
6498 (including the raw packet from network) must be freed by calling
6499 the new silc_packet_context_free function. Added also new function
6500 silc_packet_context_alloc that must be used now to allocate the
6501 context. This also means that if a routine is asynchronous from
6502 silc_[client/server]_packet_parse_type the packet context must
6503 be duplicated by calling silc_packet_context_dup. Otherwise it
6504 gets free'd after silc_[client/server]_packet_parse_type returns.
6505 Also, one must remember that if packet is duplicated then its
6506 reference count must be decresed by calling the free function as
6507 many times as it was duplicated.
6509 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6510 from both client and server.
6512 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6514 * Made joining to a channel working in router environment.
6516 * Cleaned up JOIN command on server side and create function
6517 silc_server_command_join_channel internal routine to make the
6520 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6522 * Changed silc_command_pending list to SilcDList. Also, added
6523 `ident' field to SilcServerCommandPending structure to identify
6524 the reply and to call correct callback.
6526 Added silc_server_command_pending_check function to replace the
6527 corresnponding macro. The silc_command_pending list is not
6530 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6531 to set identifier to previously allocated Command Payload. It
6532 is used to set identifier for command when resending Command
6535 * Added silc_command_payload_encode_payload to encode Command
6536 Payload buffer from SilcCommandPayload structure.
6538 * Added silc_argument_payload_encode_payload to encode Argument
6539 payload buffer from SilcArgumentPayload structure.
6541 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6543 * Changed WHOIS command to support router connection on server side.
6544 The whois request is always sent to router unless the server is
6545 standalone server. After server has received the reply from the
6546 router will it send the reply to the client.
6548 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6549 broadcast received broadcast packet. The function is used only
6550 by router. The broadcast packet is always sent to the router's
6553 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6554 render given ID to printable string, for log files for example.
6556 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6558 * Made basic router to router connections working. At least they
6559 can now connect to each other but nothing really works the way
6560 they are supposed - yet.
6562 * Added new initiator token to RouterConnection configuration
6563 file in silcd/serverconfig.[ch]. It is used to tell whether we
6564 are the initiator to the remote router or whether we'll expect
6565 the other end to connect.
6567 * Moved registering of listener task to silc_server_init, hence
6568 the server starts listenning as soon as it is run, even if it
6569 does not have connections to other routers. Let's see how well
6572 * Changed default connection retry timeouts for more suitable in
6575 * Removed cipher and such arguments from silc_idlist_add_client
6576 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6577 Added new function silc_idlist_add_data to add the keys and stuff
6580 * Added SilcIDListData structure and added it to SilcClientEntry
6581 and SilcServerEntry as their first field in the structure. This
6582 way we can explicitly cast the ID entries to the SilcIDListData
6583 structure and get common data for the entries. In past, we had
6584 to first check what type of connection it is and then cast it to
6585 correct ID entry type. Now, we can directly cast the opaque
6586 pointer to the SilcIDListData (no matter what ID entry it actually
6587 is) and get the data needed.
6589 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6591 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6592 in some circumstances even if threre were timeout tasks, though not
6593 IO tasks, but tasks anyway. Now fixed.
6595 * Defined SilcServerConnection structure to hold connection specific
6596 stuff about directly connected servers and routers. The definition
6597 is currently in silcd/server_internal.h. I thought about having
6598 a bit more important role fro this struct but for now it is used
6599 only when connecting to other server (or router actually).
6601 * Added connecting retry support in server when connecting to
6602 router(s). The retry feature implement exponential backoff
6603 algorithm. Also, added SilcServerParams structure to hold default
6604 parameters for server. For now, it include these retry settings
6605 and are hard coded. After server is moded to be as Silc Server
6606 Library this structure will be more important.
6608 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6610 * Changed client librarys channel->clients table to SilcList and
6611 changed code accordingly.
6613 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6615 * Changed client's channel table to SilcList and changed code
6616 accordingly. Also changed SilcChannelClientEntry to include back-
6617 pointer to the channel so that client entry can use that structure
6618 as list as well and we have fast cross-reference to the channel.
6619 This change dramatically decreased the complexity of channel
6620 handling with client entry and vice versa (removed one extra
6621 loop when searching for channel entry from many functions).
6623 * Changed server->sim from table to SilcDList and changed code
6626 * NAMES command can now be used from user interface. It will show
6627 the user list on the channel, neatly.
6629 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6630 Code now saves realname of the user if it becomes available.
6632 * Renamed configure.in to configure.in.pre and made ./prepare
6633 script to automatically add correct version string to
6634 configure.in which it creates from configure.in.pre.
6636 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6638 * NAMES command reply now shows users mode with the nickname when
6641 * Moved silc_client_ch[u]mode[_char] functions from
6642 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6643 place sucks, they are utility functions and should be in some
6646 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6648 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6651 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6655 * Added TRQ (efficient deque and list library) into lib/trq. This is
6656 a very good list library that is currently used in the SILC. Defined
6657 SilcList API over the library because I didn't like the API very
6658 much. See lib/trq/silclist.h for the API and examples of how to
6659 use the API. Fixed various places in the code to use the new
6660 SilcList API. The SilcList is meant for lists that has a structure
6661 already defined as a list. It is not suitable to add just some
6662 context to the list (in TRQ, the context is the list actually).
6664 So, I defined SilcDList that can be used for the purpose where
6665 predefined list structure does not exit. This can be used as
6666 such list. Now some context just can be added to the SilcDList.
6667 Currently this list is not used in the SILC just yet, though there
6668 are a lot places where this can replace dynamically allocated
6669 tables and I will fix these places, later, to use SilcDList.
6670 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6671 and use TRQ internally).
6673 Also fixed some annoying warning messages that the original TRQ
6674 code generated. Also minor changes to TRQ's Makefile.in.
6676 * Added support for querying by Client ID to both WHOIS and
6677 IDENTIFY commands into server, as required by the protocol.
6679 * Removed method function pointers from SilcBuffer structure. They
6680 weren't used to anything and just increased the context size for
6681 no good reason. This change also made silc_buffer_alloc and
6682 silc_buffer_free functions inline functions.
6684 * Disabled command flooding detection support until it's fixed so
6685 that it accepts commands in but does not execute them more than once
6688 * Added silc_net_localhost(), to return local hostname, into
6689 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6690 that must be initialized before calling silc_client_init.
6692 * Added new function: silc_server_send_notify_on_channels to send
6693 notify messages to all channels client has joined. It is assured
6694 that the message is sent only once per client.
6696 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6697 lib/silcutil/silcutil.[ch] as silc_format function. The new
6698 function is generic and is used by server as well, not only by
6699 the logging routines.
6701 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6702 the provided version string was not acceptable. Added new function:
6703 silc_ske_check_version into lib/silcske/silcske.h. The function
6704 must be implemented by the application (client or server) and it
6705 does not reside in the SKE library. The function checks the version
6706 string remote end sent.
6708 * Added back pointers (to opaque context and to SilcSocketConnection)
6709 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6711 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6712 duplicate packet context structure.
6714 * Changed `notify' client operation to send same arguments as client
6715 receives from server except for ID's. ID's are mapped to correct
6716 ID entry and that is returned. Also, if channel entry is not sent
6717 by server but the notify is for channel the channel entry is sent
6718 to application (otherwise application doesn't know that it is for
6719 channel (library gets it from packet's Destination ID)).
6721 * Added silc_client_remove_from_channels into client library to
6722 remove a client from all channels it has joined to. Used when
6723 received SIGNOFF notify from server. Added also new function
6724 silc_client_replace_from_channels to replace old ID entry with
6725 new ID entry on all channels. Used when received NICK_CHANGE
6728 * Fixed ID Cache list handling in silc_idlist_get_client in
6729 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6730 to get (or query) client by ID.
6732 * Updated TODO list.
6734 * Added connection authentication status message defined by the
6735 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6736 support for these into the code in client and server side.
6738 * Added generic function silc_client_send_command to send any command
6739 with variable argument list. Application should use this function
6740 to send commands if the command functions provided by the library
6741 does not suite for the application's user interface needs.
6743 * Added new `failure' client operation. Application is notified about
6744 received failure packet if client is executing a protocol. In this
6745 case the protocol's execution has failed.
6747 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6748 is required by the protocol.
6750 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6751 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6754 * Added status flag to SilcSKE object to indicate realtime status
6755 of the SKE protocol.
6757 * Application receives now exactly same command reply arguments as
6758 the library receives from server. However, if ID is received the
6759 corresponding ID entry is returned to the application (eg. Client
6760 ID is mapped to correct SilcClientEntry entry and that is returned).
6761 Changed command_reply client operation due to this change.
6763 * Changed all ID's in commands and in command replys as ID Payloads.
6764 Change affected both client and server side codes.
6766 All ID's sent in SILC network (with execption of ID's in SILC
6767 Packet header) are sent in ID Payload to support variable length
6770 * Server now notifies nick changes and notifies all clients on
6771 the channels about the new nickname (about the new Client ID,
6774 * Implemented CMODE command to change channel modes. Supports all
6775 channel modes defined by the protocol specs except ban and invite
6776 lists. (Also, private channel key mode is supported but support for
6777 setting private channel key in client is missing, thus, this mode
6778 has no effect on client side (except that server requires that the
6779 client uses private channel key and normal channel traffic does not
6782 Also, invite mode works per se, but INVITE command does not work
6783 yet correctly, so you can set channel as invite only channel but
6784 inviting clients to the channel does not work (it is yet to be
6785 thought what's the best way to do it).
6787 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6788 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6789 Implemented CUMODE command to change user's mode on the channel.
6790 Supports all modes defined by the protocol specs.
6792 * Added NAMES command reply to return users modes on the channel.
6794 * Removed unnecessary and slow ciphers from lib/silccrypt.
6796 * Set SO_KEEPALIVE option to connection sockets by default.
6798 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6800 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6801 redefined the Notify Payload into protocol specs.
6803 * Added silc_id_payload_parse_id to get ID directly from raw
6806 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6808 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6809 accept searching by Client ID as well.
6811 * Added support for LEAVE and SIGNOFF notify types in client library.
6813 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6814 to parse ID Payload from raw data.
6816 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6818 * Added flags parameter into silc_ske_assemble_security_properties
6819 function in lib/silcske/silcske.[ch].
6821 * Changed notify client operation to fit better for notify messages
6822 sent by server. The notify payload received from server is now
6823 passed to the application (after parsing it to SilcNotifyPayload).
6824 It is application's responsibility to retrieve the arguments
6825 from the payload and show the message the way it wants. The message
6826 sent by server is implementation specific.
6828 * Changed public keys to comply with the protocol specification.
6829 Old public keys are not supported anymore and are not compatible.
6831 * Removed nickname from Channel Payload as the latest draft removed
6832 it. The client must resolve the nickname from the NAMES command
6833 reply received when it joined the channel.
6835 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6837 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6839 * Fixed some errors in protocol specification drafts.
6841 * Created lib/silccore/silcnotify.c to implement Notify Payload
6842 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6843 generic payloads described by protocol specifications. The file
6844 includes implementations for ID Payload and Argument Payload.
6846 * Changed Command Payload implementation to use the new Argument
6847 Payload. Changed command_xxxx_payload to command_payload_xxxx
6848 to comply with SILC coding conventions.
6850 * Added suppport for Argument Payload handling in Notify Payload
6851 implementation as protocol requires it. Added the new support
6852 into server and client lib as well.
6854 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6856 * Added support for multiple nicknames on same channel. [n] is
6857 added locally to the nickname if there are more than one same
6858 nicknames on the channel.
6860 * Server now sends all nicknames that matched WHOIS request.
6861 Client also shows the list received from server.
6863 * Added TOPIC command to client side. User can now set and show
6864 current topic on channel.
6866 * Added MOTD command to client and server. Also, server sends the
6867 motd when client connects to the server.
6869 * Changed version strings to comply ISO 8601.
6871 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6873 * Fixed protocol error handling in client library. It should now
6874 cope even if the SKE fails for some reason.
6876 * Made new protocol specification drafts for submitting to IETF.
6878 * Implemented TOPIC command to server in silcd/command.c.
6880 * Added two new notify types into lib/silccore/silcnotify.h:
6881 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6882 notify nickname change and topic setting/change on a channel.
6884 * API change of command_reply operation in client library. The
6885 application gets now the status type received from server as well.
6887 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6889 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6891 * Cras fixed and optimized the packet handling even further and
6892 it should work now. Minor change to the prototype of function
6893 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6895 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6897 * Added new function into lib/silcutil/silcschedule.[ch]:
6898 silc_schedule_with_fd to select() a specified fd. The function
6899 returns after timeout expires or data arrives or goes. The
6900 function is used by packet routines to wait that all data is
6901 received from network.
6903 * Fixed data reading from network in lib/silccore/silcpacket.c.
6904 The code now assures that all data is read from the fd and then
6905 continues packet processing. This was a bug fix since the code
6906 used to drop some data in some circumstances.
6908 * Added new function into lib/silcclient/client.[ch]:
6909 silc_client_start_key_exchange to start key exchange after
6910 connection has been established to server. The code internally
6911 now uses this funtion but its main purpose was to provide it
6912 for applications that perform their own connecting. After
6913 application has created a connection it merely calls this
6914 function to start the key exchange between client and server.
6915 The library takes care of everything else after that.
6917 Updated also lib/silcclient/README to explain the usage of
6920 * Do not send to application information that connection has
6921 been established. Application gets notified it by connect
6924 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6926 * Applied cras's patch to add silc_schedule_one function. The
6927 function runs scheduler once and returns.
6929 * Fixed the scheduler after cras messed it up. The timeout
6930 handling works now as it's supposed to work.
6932 * Added into lib/silccore/ silcnotify.h to include notify
6933 message types support. Changed silc_server_send_notify*
6934 functions, in server.[ch], to support those new notify types.
6935 Added the support for the notify types into client library,
6936 as well. Added new notify client operation into ops.h in
6939 * Changed silc_server_packet_send_to_channel to send normal
6940 packets instead of just channel message packets. The function
6941 is now used to send the notify packets to channels. It is not
6942 used to send channel message packets anymore, as server never
6945 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6946 va_arg()s as it seems to require it nowadays. I guess, if SILC
6947 is compiled with older va_arg() the new code should work anyway.
6949 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6951 * Splitted core library. Core library (lib/silccore) includes
6952 now only SILC protocol specific core (and common) components.
6953 Created new utility library (lib/silcutil) that includes more
6954 generic purpose stuff. The stuff for util library was taken
6955 from the old core library. This was minor and easy split.
6957 * Created SILC Client Library (lib/silcclient) that includes
6958 implementation of the SILC client without user interface. This
6959 was major move from silc/ directory. The code has been changed
6960 so that it is transparent towards the user interface. The
6961 silc/ directory includes now the same user interface as before
6962 and it uses the new client library. Read lib/silcclient/README.
6963 Basicly, the client library performs everything else related
6964 to SILC except user interface handling. Also, configuration
6965 files are considered to be part of user interface and library
6966 does not handle them.
6968 This change also changed a lot of structures, function naming etc.
6969 Most important change was that SilcClientWindow object was
6970 renamed to SilcClientConnection in the client library. Created
6971 also new file lib/silcclient/ops.h. Also added new files
6972 silc/local_command.[ch] and silc/client_ops.[ch].
6974 All these changes were made to make it easier for user interface
6975 designers to create what ever user interface for the SILC client
6978 It is also expected that the server will be moved to lib
6979 directory as well and SILC Server Library will be created;
6980 sometimes in the future.
6982 * Removed Local commands from lib/silccore/silccommand.h as
6983 they are application specific and new client library does not
6984 handle any of those anymore.
6986 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6987 old client implementation in silc/.
6989 * Added support for callback functions in SILC_LOG_* macros.
6990 Application can now set its own callbacks that will be called
6991 instead of using the default functions that will always print
6992 the debug messages to stderr (or stdout). Also, debugging can
6993 now be disabled by setting silc_debug to FALSE and re-enabled by
6994 setting it to TRUE. Note, that logging will still work even
6995 if debugging is disabled.
6997 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6998 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6999 silc_log_reset_debug_callbacks.
7001 * To enable debugging in silc client one must give now -d
7002 option on command line.
7004 * Changed silc_schedule_init to automatically allocate task queues
7005 if they are not allocated before calling it.
7007 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7009 * Added GMP 3.1 into math library.
7011 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7013 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7014 a channel in SILC network. The packet is used by servers and
7015 routers to notify other routers that user has left a channel.
7016 This little feature was missing until now. Added the feature
7017 to protocol specification as well.
7019 Added functions: silc_server_send_remove_channel_user and
7020 silc_server_remove_channel_user into server.[ch].
7022 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7023 lib/silccore/silcpacket.h. However, they are not implemented
7026 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7028 * Fixed joining to a channel and sending channel messages
7029 between server and router. The channel message sending should
7030 now work inside a cell.
7032 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7034 * Fixed the private message sending between server and router.
7035 The private message sending should now work inside a cell.
7037 * Added silc_server_replace_id into server.[ch] to replace
7038 existing ID in the SILC network.
7040 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7041 and silc_idlist_replace_server_id into idlist.[ch] in server.
7043 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7045 * Fixed the server to server connections. Server can again now
7046 connect to router. Router to router connections probably does
7049 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7051 * Added dynamic protocol registering support. Now protocols can
7052 registered and unregistered on the fly. Patch by cras.
7054 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7056 * Added lib/contrib directory to hold routines that some platforms
7057 don't have but are needed by SILC.
7059 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7060 into lin/contrib to provide getopt() and getopt_long() for
7061 those who don't have it.
7063 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7065 * Added AWAY command to client. When away message is set and
7066 client receives a private message packet the client automatically
7067 replies to the sender with the away message.
7069 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7070 bug seemed to be the cause of recent problems when compiling
7073 * Added version detection support to SKE protocol specification
7074 and added the new changes to the SKE implementation as well.
7075 There were other minor changes in the SKE protocol as well.
7077 Many changes in lib/silcske/silcske.[ch] and in
7078 lib/silcske/payload.[ch].
7080 * Added ^U functionality, clear input line. Patch from cras.
7082 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7084 * Mainly small bugfixes on core library. Fixed some debugging
7085 logging and buffer overflow in silclog.c.
7087 * Updated config.sub and config.guess on the distribution tree.
7089 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7091 * Added command lagging support in server. Client may execute
7092 commands now only once in two seconds.
7094 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7096 * Optimized packet reception. MAC computation and checking is now
7097 also more optimized. A lot previously duplicated code is now
7098 used as generic by both client and server.
7100 * Fixed key pair generation in clientutil.c
7102 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7104 * Added into lib/silccore/silcbufutil.[ch] new function;
7105 silc_buffer_realloc.
7107 * Moved generic packet sending/encryption functions to
7108 lib/silccore/silcpacket.[ch] from client and server. Some
7109 rewriting of the functions.
7111 * Moved all generic packet reception/decryption functions to
7112 lib/silccore/silcpacket.[ch] from client and server. The
7113 packet processing is now much cleaner in both client and server.
7114 These were major changes in both client and server.
7116 * Created many common functions in server to do packet sending.
7117 Previously code were duplicated a lot, this has been removed
7120 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7122 * Rewrote major parts of the ID cache system. Don't know
7123 whether it is better now or not but at least the API is more
7126 * Major rewrite on ID cache stuff on client because of the ID
7127 cache API changes. Added idlist.c to client.
7129 * Also major rewrite on ID cache stuff on server as well.
7130 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7131 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7132 in hand, instead they are all put into the ID cache system now.
7133 All server_idlist_* routines uses ID cache now instead of
7134 traversing its own lists (those lists does not exist anymore).
7135 SilcIDList though still exists. Also, SilcXXXEntry's are
7138 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7140 * Finally made the SKE implementation compliant to the protocol
7141 specification. All mp integers are now binary encoded as
7142 opposed being HEX encoded.
7144 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7147 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7148 functions: silc_[encode/decode]_pem. Also added function
7149 silc_encode_pem_file to PEM encode with newlines ('\n') for
7152 * SILC public keys are now encoded either PEM or binary. Same
7153 option is for private keys as well. By default private keys
7154 are binary encoded and public keys PEM encoded. Silly HEX
7155 encoding were removed.
7157 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7158 function to create fingerprints.
7160 * Fixed a bug in SHA1; does not change the original data anymore.
7162 * Partly implemented INFO command on client and server side.
7163 Fixed CLEAR command. Changes to SERVER command; show current
7164 server(s) when giving command without arguments. Added
7165 VERSION command to client.
7167 * Added check to server that unregistered connections cannot
7168 execute commands (unless it is specificly allowed).
7170 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7172 * Fixed screen refresh.
7174 * Fixed channel joining bug from client. On some circumstances
7175 client tried to join to a channel it had already joined.
7177 * Added public key verification process into client's protocol.c.
7178 The client now verifies the public key from user and saves
7179 it into ~./silc/serverkeys/ directory.
7181 Added into: clientutil.[ch]: silc_client_verify_server_key.
7183 * Changed SKE protocol's silc_ske_initiator_finish function
7184 to accept callback function that verifies the received public
7185 key. Removed old silc_ske_verify_public_key function.
7187 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7189 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7190 silc_pkcs_private_key[_data]_set.
7192 * Made the password and public authentication more cleaner in
7193 server's protocol.c.
7195 * Removed historic and obsolete protocol `channel_auth' from
7196 both client and server.
7198 * Removed wrong way of sending command status messages from
7199 server to client in server's command.c. The old way violated
7200 protocol specification.
7202 Changes to silccore/silccommand.[ch]: removed
7203 silc_command_encode_status_payload -> not needed anymore,
7204 changed silc_command_encode_payload_va to accept extra
7205 argument on variable argument list. The argument type must
7206 now be provided to the function. Also, added new function:
7207 silc_command_encode_reply_payload_va which is same as
7208 normal command_encode_payload_va except command status type
7209 is provided as extra argument.
7211 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7213 * Added ~./silc directory handling. The directory includes the
7214 public and private keys for the client.
7216 Added silc_client_check_silc_dir, silc_client_create_identifier
7217 and silc_client_load_keys.
7219 * Implemented SILC protocol compliant public key. Added public
7220 and private key saving to and loading from files.
7222 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7223 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7224 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7225 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7226 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7228 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7229 silc_pkcs_load_[public/private]_key.
7231 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7233 * Added silc_server_get_route (route.[ch]) to get connection
7234 data for the fastest route for given ID.
7236 * Implemented INVITE command on client and server. The command
7237 were re-defined in the SILC Protocol Specification and the
7238 implementation now complies with the specification.
7240 * Implemented PING command on client and server.
7242 * Implemented NAMES command on client and server. The server side
7243 supports currently only normal server not router server yet.
7244 Some changes to NAMES definition in SILC protocol specification.
7246 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7248 * Implemented LEAVE command on client and server.
7250 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7251 again. This change was made to the protocol as well. Server
7252 should not violate the protocol specification anymore.
7254 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7256 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7257 was tested. SOCKS4 was not but should work anyway.
