1 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Changed all integer type names:
4 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
5 to avoid collisions with other libraries using same type names
8 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
10 * Added `prefer_ipv6' argument to the functions
11 silc_net_gethostbyname[_async]. If it is TRUE it will return
12 IPv6 address over IPv4. If FALSE IPv4 address is returned
13 even if IPv6 address was found. Affected files
14 lib/silcutil/silcnet.[ch].
16 * Added support silc_net_create_connection[_async] to fallback
17 to IPv4 address if IPv6 address could not be used (like if
18 it doesn't work on a specific system). Affected file in

30 application does not need to define them. Affected file
31 includes/silcincludes.h.
33 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
34 old name went against naming convention. Applications now
35 include "silcclient.h" instead of "clientlibincludes.h".
36 Removed includes/clientlibincludes.h, it is redundant now.
38 * Renamed includes/version.h to silcversion.h.
40 * Added really preliminary support for OS/2 into the util
41 library. Only thread & mutex API is implemented, others
42 are still to be implemented. Created the lib/silcutil/os2/
43 directory. Created also file includes/silcos2.h.
45 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

93 Affected file lib/silcclient/client.c.
95 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
97 * ROBOdoc documented the lib/silcske/silcske.h, and improved
98 the SKE interface a bit.
100 * Fixed padding problem in PKCS#1. The padding was not actually
101 random since the random number generator was used incorrectly.
102 This security bug affects only when encrypting with PKCS#1, and
103 it is not currently used at all in SILC. SILC only use signing
104 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
106 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

172 * Added new configuration options and blocks:
173 keepalive_secs, reconnect_count, reconnect_interval,
174 reconnect_interval_max, reconnect_keep_trying and
175 require_reverser_lookup. Added ConnectionParam block, and
176 implemented the connection parameters when connecting as
177 initiator and when accepting connections as responder.

180 whether given configuration value has been given already.
182 Affected files silcd/serverconfig.[c], server.[c].
184 * Splitted the doc/example_silcd.conf.in. Separated the crypto
185 algorithm parts and created new file silcalgs.conf, that
186 is now included from the example_silcd.conf.in.
188 * Optimized the silc_server_connect_to_router_second to take
189 the connection configuration object from the SilcServerConnection
190 object instead of finding it during the connecting phase.
191 Added the configuration object to SilcServerConnection struct.
192 Affected files silcd/server_internal.h, server.c.
194 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

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

276 * Fixed the file transfer's key agreement payload to include
277 zero port also if the hostname is NULL because it could not
280 Call file transfer monitor callback now also if error occurs
281 during key agreement protocol.
283 Changed the silc_client_file_send interface to return the
284 SilcClientFileError instead of session id. The session ID
285 is returned into pointer provided as argument.

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

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

354 users list to SilcHashTable. The affected files are
355 lib/silcclient/idlist.[ch].
357 * Fixed a bug in hash table tarversing. While the hash table
358 is traversed with SilcHashTableList the table must not be
359 rehashed. It is now guaranteed that auto rehashable tables
360 are not rehashed while tarversing the list. Also defined that
361 silc_hash_table_rehash must not be called while tarversing
362 the table. Added function silc_hash_table_list_reset that must
363 be called after the tarversing is over. The affected files are
364 lib/silcutil/silchashtable.[ch].
366 * Changed all hash table traversing to call the new
367 silc_hash_table_list_reset in server and in client library.
369 * Added function silc_client_on_channel to return the
370 SilcChannelUser entry if the specified client entry is joined
371 on the specified channel. This is exported to application as
372 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

386 sender's old command identifier was not saved back to the
387 sender's command context, fixed now. The affected file is
390 * Create the key in JOIN command of the router did not return
391 the channel key, added check for this. Affected file is
394 * Fixed a channel ID update bug in JOIN command reply. Do
395 not directly upgrade the ID but call the function
396 silc_idlist_replace_channel_id if the ID was changed.
397 Affected file silcd/command_reply.c.
399 * Fixed memory leaks from command calling if it would fail.
400 Affected file silcd/command.c.

426 * Fixed memory leaks in silc_server_create_new_channel*
427 functions. Affected file silcd/server.c.
429 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
430 which ID was changed. This way the router will send the
431 user list for the channel again, and server won't be in
432 desync in some rare circumstances. Affected file is
433 silcd/packet_receive.c.
435 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

499 * Removed the SilcClientCommandDestructor from the client
500 libary, it is not needed anymore. Affected files are
501 lib/silcclient/silcapi.h, command[_reply].[ch],
502 client_notify, idlist.c.
504 * Fixed GETKEY command to first resolve client, and then

506 of resolving both at the same time. Affected file is
507 lib/silcclient/command.c.
509 * Added silc_client_start_key_exchange_cb and lookup the
510 remote hostname and IP address before starting the key
511 exchange with server. The affected file is
512 lib/silcclient/client.c.
514 * The server's public key is now saved using the IP address
515 of the server and not the servername for the filename.
516 The hostname public key filename is checked as an fall back
517 method if the IP address based filename is not found.
519 Fixed the GETKEY command to save the fetched server key
522 Print the remote server's hostname now when new key is
523 received during connection process. Affected file is
524 irssi/src/silc/core/client_ops.c.
526 * Return always our own public key to the client if it asks
527 for it with GETKEY command. Affected file silcd/command.c.

545 the client becoming valid after the server becomes back
546 online. Affected file silcd/server_util.c.
548 * Added `sock_error' field into the SilcSocketConnection
549 context. When error occurs during socket operation (read
550 or write) the error is saved. Added also new function
551 silc_socket_get_error to return human readable socket error
552 message. Affected files are lib/silcutil/silcsockconn.[ch],
553 lib/silcutil/unix/silcunixsockconn.c, and

561 really was created or not and set it according that.
563 Fixed the JOIN command to use the client entry's current
564 ID during the joining procedure instead of the one it sent
565 in the command (it is checked though), since it can change
566 between the packet processing and command processing, and
567 would just case unnecessary pain in the client end. Affected
568 file silcd/command.c.
570 * Fixed a channel key payload sending to use correct channel
571 ID when the server was forced to change the channel's ID by
572 router. Router sent the key payload with the old Channel ID.
573 Affected file silcd/packet_receive.c.
575 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
577 * Call silc_server_save_channel_key only if the key payload
578 was provided in the JOIN command's command reply. Affected
579 file silcd/command_reply.c.
581 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
583 * Fixed silc_mp_sizeinbase to return the value correctly with
584 MPI. Affected file lib/silcmath/mp_mpi.c.
586 * Fixed the stop_server signal to correctly stop the scheduler
587 and gracefully stop the server when SIGTERM or SIGINT signals
588 are received. Affected file silcd/silcd.c.
590 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
592 * Simple handling of TERM and HUP signals. Also added some log
593 flushing call around. Affected file is
596 * Fixed small bugs in silclog.c. Now buffering output will take
597 effect after 10 seconds since startup: This will ensure that
598 no important startup messages are lost. Also output redirection
599 will preserve original format ([Date] [Type] message).
600 Affected file is lib/silcutil/silclog.c.
602 * Added two options to the config file, in the logging section:
603 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
604 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
606 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
608 * Do not print the warning about log files not being initialized
609 more than once to avoid excess logging. Affected file is
610 lib/silcutil/silclog.c.
612 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
613 the SIM copying in make install in Makefile.am.pre.
615 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
617 * Rewritten silclog APIs. Globally interesting changes follows:
618 silc_log_set_files() changed to silc_log_set_file().
619 silc_log_set_callbacks() changed to silc_log_set_callback().
620 ROBOdoc documented silclog header file.
621 SilcLogCb now returns bool to wether inihibit the default
622 handler or not (to keep the old behaviour return always TRUE).
623 The new APIs should also fix the problem of the
624 silcd_error.log file that was written in the current directory.
627 Log files streams will remain opened after silc_log_set_file()
628 call, means less CPU usage notably on high traffic servers.
629 File streams are now full buffered, and flushed to the disk
630 every 5 minutes, lesses HD activity and CPU usage.
631 Messages can be redirected, allowing admins to configure
632 one single logfile for all server messages.
633 the silc_log_quick global variable to activate fast-logging.
634 Affected files lib/silcutil/silclog.[ch]
636 * Changed some code to conform new silclog APIs. Affected
637 files are doc/example_silcd.conf.in, silcd/server.c
638 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
641 * Fixed a memory leak that could occur in some situations.
642 Affected file silcd/serverconfig.c.
644 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
646 * Added the silc_client_del_client to remove the client from
647 all channels as well. Affected file lib/silcclient/idlist.c.
649 * Fixed the client library to correctly remove the client
650 from all channels when the client entry is being destroyed.
651 Affected file lib/silcclient/client_notify.c, command.c.
653 * Added auto-nicking support to the client library. If the
654 applicatio now sets client->nickname it will be sent to the
655 server after connecting by the library. This way for example
656 SILCNICK (or IRCNICK) environment variables will have effect
657 and always change the nickname automatically to whatever
658 it is wanted. Affected file lib/silcclient/client.[ch].
660 * Renamed silc_server_command_bad_chars to the
661 silc_server_name_bad_chars and moved it to the
662 silcd/server_util.[ch]. Added also new function
663 silc_server_name_modify_bad to return nickname that
664 includes bad characters as new nickname without those
665 bad characters. This check and modify is now used in
666 silc_server_new_client when the username is initially set
667 as nickname, so it must be checked to be valid nickname.
668 Affected file silcd/packet_receive.c.
670 * The nickname length is now taken from the packet for real
671 and not trusted to strlen() since it clearly can return
672 wrong length for nickname including bad characters. This
673 also applies to channel names. Affected file silcd/command.c.
675 * Removed the lib/silcsilm/modules directory. Modules are now
676 compiled into the lib/silcsim. Fixed the copying of the
677 modules to follow symbolic links in Makefile.am.pre.
679 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
681 * Fixed silc_string_regexify list creation. Fixes bugs with
682 BAN and INVITE commands in server. The affected file is
683 lib/silcutil/unix/silcunixutil.c.
685 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
687 * Removed the command destructor entirely from the server's
688 command and command reply routines. It is not needed, and
689 its usage was buggy and caused crashes. Affected files are
690 silcd/command[_reply].[ch].
692 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
694 * Cancel protocol and NULL sock->protocol if timeout
695 occurred during protocol. Affected file silcd/server.c.
697 * Cancel protocol timeouts always before calling the final
698 callback, to assure that after final callback is called
699 no other state will be called for the protocol anymore.
700 Affected file silcd/protocol.c.
702 * Print error log if incoming connection configuration could
703 not be found. Affected file silcd/server.c.
705 * Fixed JOIN command to correctly save the founder mode
706 to the client on normal SILC server, when the channel
707 was created by the router. Affected file silcd/command.c.
709 * Fixed LIST command (hopefully) to send correct reply
710 packets. Affected file silcd/command.c.
712 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
714 * The silc_packet_receive_process now returns FALSE if the
715 read data was invalid packet, and TRUE if it was ok.
717 The server now checks that if unauthenticated connection
718 sends data and its processing fails the server will close
719 the connection since it could be a malicious flooder.
721 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
723 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
725 * Make sure the warning about error opening a log file is
726 printed only once and not everytime it fails (produces
727 too much useless log). Affected file lib/silcutil/silclog.c.
729 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
731 * Made the silc_server_daemonise() function more readable.
732 Affected file silcd/server.c.
734 * Pid file is now optional, the user may comment it out from
735 the config file. Removed define SILC_SERVER_PID_FILE, we
736 don't need a default any longer. Affected file
737 configure.in.pre, lib/Makefile.am.pre.
739 * Make some use of the pid file. The server now dies at startup
740 if it detects a valid pid file on his path. The server would
741 die anyway in this circumstance, because of the bind() failure.
742 Affected file silcd/silcd.c.
744 * No longer compiling lib/dotconf.
746 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
748 * Fixed JOIN command parsing not to crash. Affected file
749 lib/silcclient/command.c.
751 * Fied the NICK_CHANGE notify to add the new client entry
752 even it is resolved. This removes an <[unknown]> nick
753 thingy bug in the client. Affected file is
754 lib/silcclient/client_notify.c.
756 * Do not try to allocate 0 bytes (efence does not like it)
757 in lib/silccore/silccomand.c when encoding payload.
759 * Do not take IRCNICK as nickname in Irssi SILC client since
760 it is not possible to set nickname before hand connecting
761 the server (TODO has an entry about adding auto-nicking
764 * Changed the silc_server_command_pending to check whether
765 there already exists an pending entry with the specified
766 command, command identifier and pending callback. This is
767 to fix IDENTIFY and WHOIS related crashes that may register
768 multiple pending commands with same identifier. Affected
769 file silcd/command.c.
771 * Fixed the server to reconnect to the router even if it
772 was already reconnecting and EOF was received. This to
773 fix a possibility that the server wouldn't ever try to
774 auto-reconnect to the router. Affected file silcd/server.c.
776 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
778 * Fixed the server's password authentication to use the
779 length of the locally saved password, and not the one
780 sent in the packet. Affected file silcd/protocol.c.
782 * Fixed same password authentication problem in the
783 Authentication Payload handling routines in
784 lib/silccore/silcauth.c.
786 * Yet another password authentication problem fixed with
787 channel password handling in silcd/command.c.
789 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
791 * If first character of string in silc_parse_userfqdn is '@'
792 then do not parse it. Affected file is
793 lib/silcutil/silcutil.c.
795 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
797 * Fixed minor bug in IDENTIFY command reply sending, which
798 caused various weird problems during JOIN when it was
799 resolving names for users. Affected file silcd/command.c.
801 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
803 * Fixed the IDENTIFY command reply sending to chech better valid
804 clients. It was possible to send incomplete list of replies.
805 Affected file silcd/command.c.
807 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
809 * Added silc_client_command[s]_[un]register functions now to
810 dynamically register the commands in client library. Removed
811 the static table of commands. This allows the client library
812 to call commands without causing the application to know about
813 what commands library has called.
815 Removed the INFO command reply kludge to detect when the command
816 was called by library. Now library use its own command reply
817 function for INFO command.
819 Added function silc_client_command_call to call a command.
820 Application can use it to call command, not access the structure
823 Now all commands that are sent by the client library (not
824 explicitly sent by application) use own command reply functions.
826 Affected files around lib/silcclient/ and in
827 irssi/src/silc/core/.
829 * Fixed the WHOIS command reply sending to chech better valid
830 clients. It was possible to send incomplete list of replies.
832 Fixed the WHOIS and IDENTIFY to send the request to router
833 if normal server did not do it and did not find any results.
835 Affected file silcd/command.c.
837 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
839 * Moved the internal data from SilcClient context into its
840 own file, not accesible to application. Affected files
841 lib/silcclient/client.h and lib/silcclient/client_internal.h,
842 and other files in client library.
844 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
846 * Added doc/examples installation target in Makefile.am.pre.
849 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
851 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
852 commands the found client entry will be removed from the
853 cache, after notifying application about the error. Affected
854 file lib/silcclient/command_reply.c.
856 * Changed the /MSG to check for exact nickname user gave, and
857 not let `nick' match `nick@host' if it is only one found. Now,
858 user must type the exact nickname (like nick@host2) even if
859 there are no more than one same nicks found. This is to avoid
860 a possibility of sending nickname to wrong nickname since
861 `nick' could match `nick@host'. Affected file is
862 irssi/src/core/silc-servers.c.
864 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
866 * Do not print "you are now server operator" or similar when
867 giving /away command. Affected files are
868 irssi/src/silc/core/client_ops.c, silc-servers.h.
870 * Made the silc_server_command_pending_error_check to send
871 the same command reply payload it received back to the
872 original sender of the command. This way all arguments
873 that was received by the server will be received by the
874 client too. Affected file silcd/command.c.
876 * Added the silc_idcache_add to return the created cache entry
877 to a pointer. Affected file lib/silccore/silcidcache.[ch].
879 * Add global clients to expire if they are not on any channel.
880 This is because normal server will never know if they signoff
881 if they are not on any channel. The cache expiry will take
882 case of these entries. This is done by normal servers only.
883 The affected files are silcd/command_reply.c,
884 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
886 * If server receives invalid ID notification for WHOIS or
887 IDENTIFY and the ID exists in the lists, it is removed.
888 Affected file silcd/command_reply.c.
890 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
891 in client then client entry that it matches is searched and
892 the nickname is printed on the screen for user. Affected
893 file irssi/src/silc/core/client_ops.c.
895 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
897 * Use cache entry expire time in the LIST command reply to
898 purge old entries from the cache after the LIST command
899 reply has been received. This way we don't have non-existent
900 entries in the cache for too long. Affected file is
901 silcd/command_reply.c.
903 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
905 * If we are normal server, and we've not resolved client info
906 in WHOIS or IDENTIFY from router, and it is global client,
907 we'll check whether it is on some channel. If it is not
908 then we cannot be sure about its validity and will resolve it
909 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
910 file silcd/command.c.
912 * Search channel by name (if possible) rather than by ID
913 in IDENTIFY command's command reply. Affected file is
914 silcd/command_reply.c.
916 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
918 * Distribute to the channel passphrase in CMODE_CHANGE notify.
919 Updated specs and implemented it. Affected file silcd/command.c,
920 silcd/packet_send.c and silcd/packet_receive.c.
922 * Implemented the <founder auth> payload handling in the JOIN
923 command. If provided all conditions for channel joining
924 except requirement to provide correct passphrase can be
925 overrided by the channel founder. Updated the protocol specs.
926 Affected file silcd/command.c.
928 Added support for founder auth in JOIN command in client
929 library. Fixed the parsing of the JOIN command now to support
930 all options as they should be. The affected file is
931 lib/silcclient/command.c.
933 * Optimized the WHOIS and IDENTIFY commands to send the request
934 to router only if it includes nicknames or other names. If
935 they include only IDs then check the local cache first before
936 routing. Affected file is silcd/command.c.
938 * Added channels topic announcements. Affected file is
939 silcd/packet_receive.c and silcd/server.c.
941 * Fixed the silc_server_send_notify_topic_set to really destine
942 the packet to channel. Affected file silcd/packet_send.c.
944 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
945 library. Affected file lib/silcclient/client_notify.c.
947 * Added UMODE announcements. Affected file silcd/server.c.
949 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
951 * Memory leak fixes in:
953 lib/silcutil/silcsockconn.c
954 lib/silcske/silcske.c
957 lib/silccrypt/silcpkcs.c
958 lib/silccore/silccommand.c
959 lib/silccore/silcidcache.c
964 * ROBOdoc documented the lib/silcske/groups.h file and a
965 bit changed the interface for better.
967 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
969 * Update the client entry context in the ID cache after
970 nick change. Affected file lib/silcclient/command.c.
971 Fixes the CUMODE command when regaining founder privileges,
972 and a little WHOIS problem.
974 * Fixed silc_net_gethostbyname to correctly call the
975 inet_ntop. Affected file lib/silcutil/silcnet.c.
977 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
979 * Added IPv6 support checking to the configure.in.pre, added
980 also --enable-ipv6 option to override the check. Affected
981 file configure.in.pre.
983 * The silc_thread_create now calls the start function
984 directly if threads support is not compiled in. Removes
985 ugly #ifdef's from generic code. Affected files are
986 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
988 * Added silc_net_gethostby[name/addr]_async to asynchronously
989 resolve. Affected files are lib/silcutil/silcnet.[ch].
991 * Added support for rendering IPv6 based server, client and
992 channel IDs. Affected file lib/silcutil/silcutil.c.
994 * Added support for creating IPv6 based server IDs. Affected
995 file is silcd/serverid.c.
997 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
999 * Added silc_net_gethostby[addr/name] into the
1000 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1001 routines. Added silc_net_is_ip[4/6]. Affected file is
1002 lib/silcutil/unix/silcunixnet.c. All routines that take
1003 address as argument now supports both IPv4 and IPv6 addresses.
1005 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1007 * Fixed LIST command reply sending in server. Affected file
1010 * Server now sends the kicker's client ID in the KICK notify
1011 to the kicked client. Affected file silcd/command.c.
1013 * The client library now parses the kickers client ID and
1014 UI displays it. Affected files lib/silcclient/client_notify.c
1015 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1017 * Made all payload parsing function prototypes consistent.
1018 They all take now const unsigned char * and uint32 pair as
1019 the payload data instead of SilcBuffer. Changes all around
1020 the source tree. Other unsigned char* -> const unsigned char*
1021 changes around the tree as well.
1023 * Optimized SFTP client and server packet sending not to
1024 allocate new buffer for each packet but to recycle the
1025 first allocated buffer. Affected files are
1026 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1028 * Optimized the SFTP client to use SilcList instead of
1029 SilcDList for requests, because it is faster. Affected file
1030 is lib/silcsftp/sftp_client.c.
1032 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1033 into lib/silccore/silcid.[ch].
1035 Renamed silcpayload.[ch] into silcargument.[ch].
1037 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1039 * If client entry is deleted with active key agreement
1040 session, abort the session.
1042 The silc_client_abort_key_agreement now calls the completion
1043 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1045 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1048 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1050 * Don't use __restrict in older GCC's. Affected file is
1051 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1053 * silc_net_localhost now attempts to reverse lookup the
1054 IP/hostname. Affected file lib/silcutil/silcnet.c.
1056 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1057 command. It can be used to gain founder privileges at
1058 the same time when joining the channel.
1060 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1061 kicker's client ID as well. Updated protocol specs.
1063 Defined that the server must send SILC_COMMAND_IDENTIFY
1064 command reply with error status to client who sent
1065 private message with invalid client ID.
1067 Updated the protocol specification.
1069 * Added silc_server_send_command_reply to send any
1070 command reply. Affected file silcd/packet_send.[ch].
1072 * Added silc_id_payload_encode_data to encode ID payload
1073 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1075 * The server now send IDENTIFY command reply with error
1076 status if client ID in private message is invalid. Affected
1077 file silcd/packet_receive.c.
1079 * Save the server key file with server's IP address in
1080 the filename instead of hostname. The affected file is
1081 irssi/src/silc/core/client_ops.c.
1083 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1085 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1088 * Added libtool support for compiling shared objects in
1089 lib/silcsim. Affected file configure.in.pre and
1090 lib/silcsim/Makefile.am. Original patch by cras.
1092 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1094 * Pid file configuration, and server's config file fixes
1095 patch by toma. Updated CREDITS file.
1097 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1099 * Fixed silc_client_channel_message to not try to decrypt
1100 the message twice if it resolved the destination client
1101 information. This could cause of dropping one channel
1102 message. Affected file lib/silcclient/client_channel.c.
1104 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1106 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1107 lib/silcclient/client.c. This function is used when the SILC
1108 Client is run under some other scheduler, or event loop or
1109 main loop. On GUI applications, for example this may be
1110 desired to used to run the client under the GUI application's
1111 main loop. Typically the GUI application would register an
1112 idle task that calls this function multiple times in a second
1113 to quickly process the SILC specific data.
1115 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1117 * Fixed silc_server_drop() for dropping the supplementary
1118 groups as well, this could cause a security hole on some
1121 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1123 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1126 * Write PID file after dropping privileges. Added -F option
1127 to run server on foreground. A patch by debolaz.
1128 Affected files silcd/server.c, silcd/silcd.c.
1130 * Fixed MOTD to return the MOTD file server name. Affected
1131 file silcd/command.c.
1133 * Added INFO command reply handling to the Irssi SILC Client.
1134 Affected file irssi/src/silc/core/client_ops.c.
1136 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1138 * Fixed the silc_idcache_list_* routines to really support
1139 the dynamic list. Fixes a crash. Affected file is
1140 lib/silccore/silcidcache.c.
1142 * Fixed the LIST command reply to really call LIST command's
1143 pending callbacks. Affected file silcd/command_reply.c.
1145 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1147 * Update conn->local_entry->nickname after giving NICK
1148 command. Affected file lib/silcclient/command.c.
1150 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1152 * Added the [pid] option to the silcd configuration file
1154 Affected files: serverconfig.[ch] and silcd.c
1156 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1158 * Save fingerprint in WHOIS command reply in server.
1159 Affected file silcd/command_reply.c.
1161 * Fixed NICK commands pending callback registration.
1162 Affected file lib/silcclient/command.c.
1164 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1166 * Use ++server->cmd_ident when sending commands in server,
1167 instead of random number. Affected file silcd/command.c.
1169 * Fixed GETKEY command reply to call actually GETKEY pending
1170 command callbacks. Affected file silcd/command_reply.c.
1172 * A bit stricter check for nicknames. Check for same nickname
1173 in NICK command also. Affected file silcd/command.c.
1175 * Do not call INFO command everytime client ID changes, only
1176 during first connecting. Affected file lib/silcclient/client.c.
1178 * Set the new nickname only after successful command reply for
1179 NICK command is returned by server. Affected file
1180 lib/silcclient/command.c.
1182 * Remove nicknames from nicklist during server_signoff notify.
1183 Should fix /NAMES bit more. The affected file is
1184 irssi/src/silc/core/silc-channels.c.
1186 * Added `fingerprint' field to the SilcIDListData in the
1187 silcd/idlist.h to hold the fingerprint of the client's
1190 Send the fingerprint of the client's public key in WHOIS
1193 Affected files silcd/command.c, and silcd/idlist.[ch].
1195 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1196 create fingerprint from given data.
1198 * Show the fingerprint of the client's public key in WHOIS.
1199 Affected files irssi/src/module-formats.[ch] and
1200 irssi/src/silc/core/client_ops.c.
1202 * Format the multiple same nicknames also during JOIN and
1203 NICK_CHANGE notifys. Affected file is
1204 lib/silcclient/client_notify.c.
1206 * Do not print error on screen for invalid private message
1207 payload since it can come if someone is sending private
1208 messages with wrong key. Affected file
1209 lib/silccore/silcprivate.c.
1211 * Fixed multiple concurrent /PING crash. Affected file
1212 lib/silcclient/command.c.
1214 * Changed the wrong ID encoding. All IP addresses must be
1215 in MSB first order in encoded format. They were encoded
1216 wrong and was in LSB format. Affected files are
1217 silcd/serverid.c, lib/silcutil/silcutil.c.
1219 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1221 * Call the `connect' client operation through the scheduler
1222 in case of error. Affected file lib/silcclient/client.c.
1224 * Call the `failure' client operation even if the error
1225 occurred locally during a protocol. Affected file is
1226 lib/silcclient/protocol.c.
1228 * Added support of sending LIST command to router from normal
1229 server. This way normal server can get list of all channels
1230 in the network too. Fixed the channel list sending in the
1231 server too. Affected files are silcd/command.c, and
1232 silcd/command_reply.[ch].
1234 * Added silc_server_update_channels_by_server and
1235 silc_server_remove_channels_by_server. They are used during
1236 disconnection of primary router and in backup router protocol.
1237 Affected file silcd/server_util.[ch], silcd/server.c and
1238 silcd/server_backup.c.
1240 * Fixed channel adding to global list in IDENTIFY command
1241 reply in server. Affected file silcd/command_reply.c.
1243 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1245 * If the incoming packet type is REKEY or REKEY_DONE process
1246 that packet always synchronously. Fixes yet another MAC
1247 failed error on slow (dialup) connections. Affected file
1248 lib/silcclient/client.c and silcd/server.c.
1250 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1252 * Call check_version SKE callback for initiator too. Affected
1253 file lib/silcske/silcske.c.
1255 * Implemented fix for security hole found in the SKE that was
1256 fixed in the specification few days back; the initiator's
1257 public key is now added to the HASH value computation.
1258 Added backwards support for the old way of doing it too, for
1259 old clients and old servers. Affected file is
1260 lib/silcske/silcske.c.
1262 * Enabled mutual authentication by default in SKE. If initiator
1263 is not providing mutual authentication the responder will
1264 force it. This will provide the proof of posession of the
1265 private key for responder. The affected files are
1266 lib/silcclient/protocol.c and silcd/protocol.c.
1268 * Do not cache anymore the server's public key during SKE.
1269 We do mutual authentication so the proof of posession of
1270 private key is done, and if the server is authenticated in
1271 conn auth protocol with public key we must have the public
1272 key already. Affected file silcd/protocol.c.
1274 * Added new global debug variable: silc_debug_hexdump. If
1275 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1276 file lib/silcutil/silclog.[ch].
1278 * Fixed compilation warning due to char * -> const char *.
1279 Affected files lib/silcutil/silcnet.h, and
1280 lib/silccore/silcauth.[ch].
1282 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1284 * Fixed CMODE command when new channel key was created. If
1285 the creation failed the old key was removed. Next time giving
1286 same command would crash the server since the old key was
1287 freed already. Affected file silcd/command.c.
1289 * Fixed the silc_server_announce_get_channels to not crash
1290 on reconnect. Affected file silcd/server.c.
1292 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1294 * Added silc_log_set_debug_string function to set a regex
1295 string to match for debug output. Only the function names,
1296 or filenames matching the given debug string is actually
1297 printed. This way it is possible to filter out those debug
1298 strings that user is not interested in.
1300 Fixed a bug in silc_string_regexify.
1302 Affected files lib/silcutil/silclog.[ch], and
1303 lib/silcutil/unix/silcunixutil.c.
1305 * Changed the -d options in both server and Irssi SILC client
1306 to take the debug string as argument. Affected files
1307 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1309 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1311 * Added silc_hash_babbleprint to create a Bubble Babble
1312 Encoded fingerprint. The encoding is developed by Antti
1313 Huima (draft-huima-babble-01.txt), and it creates human
1314 readable strings out of binary data. Affected file
1315 lib/silccrypt/silchash.[ch].
1317 * Print the babble print now in addition of fingerprint as well
1318 in Irssi SILC client. Affected files are
1319 irssi/src/fe-common/silc/module-formats.[ch],
1320 irssi/src/fe-common/silc/core/client_ops.c.
1322 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1324 * Fixed a security problem found in SKE. The initiator's
1325 public key too is now added to the HASH hash value creation
1326 which is signed by the responder to create the SIGN value.
1327 This will prevent anyone in the middle to lie to the responder
1328 about the initiator's public key. If this is done now, the
1329 man in the middle will get caught. Updated the protocol
1332 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1334 * Better installation directory handling. Configure module
1335 paths and other paths automatically to example_silc* files
1336 in doc/. A patch by toma.
1338 * Fixed compiler warning from MPI library, and from SILC RNG.
1341 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1342 It can be configured with ./configure. A patch by toma.
1344 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1346 * Find correct make to use in prepare-clean. A patch by
1347 toma. Affected file prepare-clean.
1349 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1351 * Added irssi variables use_auto_addr, auto_bind_ip,
1352 auto_bind_port and auto_public_ip.
1354 * Changed the interface for silc_client_send_key_agreement
1355 in lib/silcclient/silcapi.h
1359 irssi/src/silc/core/silc-core.c
1361 lib/silcclient/silcapi.h
1362 irssi/src/silc/core/silc-channels.c
1363 lib/silcclient/client_keyagr.c
1366 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1368 * Added silc_pkcs_public_key_compare to compare two
1369 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1371 * Check that the client who set the founder mode on the
1372 channel is the same client that is giving the founder
1373 mode to itself. It is done by comparing the saved public
1374 key (it is saved even in the authentication is passphrase).
1375 Affected file silcd/command.c.
1377 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1379 * Do not process packet for disconnected socket connection.
1380 Affected file lib/silccore/silcpacket.c.
1382 * Process the DISCONNECT packet through scheduler in the
1383 client library. Affected file lib/silcclient/client.c.
1385 * Fixed the silc_client_packet_parse to not to increase
1386 the packet sequence number if the conn->sock and the
1387 current socket connection is not same. This can happen
1388 for example during key agreement when the conn includes
1389 multiple socket connections (listeners). Affected file
1390 lib/silcclient/client.c.
1392 * The sender of the file transfer request now provides also
1393 the pointer (listener) for the key exchange protocol. If
1394 the listener cannot be created then it sends empty key
1395 agreement and lets the receiver provide the listener.
1397 Added `local_ip' and `local_port' arguments to the
1398 silc_client_file_send. If they are provided they are used,
1399 if not then it will attempt to find local IP address, if
1400 not found or bind fails then the remote client will provide
1403 Affected files are lib/silcclient/client_ftp.c and
1404 lib/silcclient/silcapi.h.
1406 * Extended the FILE SEND command to support defining the
1407 local IP and port for key exchange listener. They are
1408 optional. Affected file irssi/src/silc/core/silc-servers.c.
1410 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1412 * Defined to WHOIS command reply the sending of fingerprint
1413 of the client's public key (if the proof of posession of the
1414 corresponding private key is verified by the server).
1415 Updated to the protocol specification.
1417 * Added support of receiving the client's public key's
1418 fingerprint in command reply in client library. Affected
1419 file is lib/silcclient/command_reply.c, and
1420 lib/silcclient/idlist.[ch].
1422 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1424 * Do not send over 128 chars long nickname to the server
1425 in NICK command. Affected file lib/silcclient/command.c.
1427 * Do not send over 256 chars long channel names to the server
1428 in JOIN command. Affected file lib/silcclient/command.c.
1430 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1432 * Assure that silc_server_close_connection cannot be called
1433 twice for same socket context. Affected file is
1436 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1438 * Send error message to application if opening file for
1439 writing during file transfer fails. Affected file is
1440 lib/silcclient/client_ftp.c.
1442 Remove all file transfer sessions for a client that we're
1443 removing from ID cache.
1445 Affected file is lib/silcclient/client_ftp.c.
1447 * Fixed silc_net_addr2bin to return correct address. Affected
1448 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1450 * Fixed file transfer session removing on signoff notify.
1451 Affected file irssi/src/silc/core/silc-servers.c.
1453 * Added the SilcClientFileError to be returned in the monitor
1454 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1455 Affected file lib/silcclient/silcapi.h.
1457 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1459 * Fixed a crash in silc_client_ftp_free_sessions and
1460 silc_client_ftp_session_free_client. Affected file
1461 lib/silcclient/client_ftp.c.
1463 * Added `disabled' field in the SilcChannelEntry in the server
1464 to indicate if the server entry is disabled. Affected file
1465 silcd/idlist.h, silcd/command[_reply].c.
1467 * SILC server adds now /var/run/silcd.pid everytime it is
1468 started. Affected file silcd/silcd.c.
1470 * Added silc_server_packet_send_clients to send a packet to
1471 the provided table of client entries. Affected file
1472 silcd/packet_send.[ch].
1474 * Fixed a crash in client resolving in client_prvmsg.c in
1475 client library. Affected file lib/silcclient/client_prvmsg.c.
1477 * Do not actually remove the client directly from ID cache
1478 during SERVER_SIGNOFF, but invalidate it. This way we
1479 preserve the WHOWAS info for the client. Affected file
1480 silcd/server_util.c.
1482 * Fixed SERVER_SIGNOFF notify handling in the server. The
1483 server is now able to process incoming SERVER_SIGNOFF notify
1484 for a server that it doesn't even know about. It will remove
1485 the clients provided in the notify. Affected file
1486 silcd/packet_receive.c.
1488 * Check for partial packet in data queue after every packet that
1489 was found from the queue. Return and wait for more data if
1490 there is partial data in queue. Affected file is
1491 lib/silccore/silcpacket.c.
1493 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1497 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1498 Affected files lib/silcclient/silcapi.h and
1499 lib/silcclient/client_ftp.c.
1501 * Check that newsize in silc_buffer_realloc is larger than
1502 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1504 * Added better monitor of file transfers. It now monitors
1505 key agreement protocol during the file transfer too. Added
1506 error reporting too. Affected files
1507 irssi/src/silc/core/silc-servers.c,
1508 irssi/src/fe-common/silc/module-formats.[ch].
1510 * Wrote a help file for FILE command.
1512 * Added silc_rng_global_get_byte_fast to get not-so-secure
1513 random data as fast as possible. Random data is read from
1514 /dev/urandom if available and from the SILC RNG if not
1515 available. It is used in padding generation. Affected file
1516 lib/silccrypt/silcrng.[ch].
1518 * All packets in client library are now processed synchronously.
1519 Optimized packet processing a lot. Affected file
1520 lib/silcclient/client.c.
1522 * All server connection packets are processing synchronously
1523 now in server, to optimize packet processing. Affected file
1526 * Include files are installed now only in Toolkit distribution
1527 if make install is given. Affected files: all Makefile.am's.
1529 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1531 * Assure that silc_client_notify_by_server_resolve does not
1532 resolve the client information multiple times. If it cannot
1533 be found by the first it cannot be found at all. Affected
1534 file lib/silcclient/client_notify.c.
1536 * Fixed WHOWAS command reply calling. Affected file
1537 lib/silcclient/command_reply.c.
1539 * Removed all references to silc_idlist_get_client from the
1540 Irssi SILC client since that call is internal call used by
1541 the library. The Irssi SILC client will use now client
1542 retrieval functions found in silcapi.h.
1544 * Fixed a bug in resolving nickname info before sending
1545 private message. It used freed memory. Affected file
1546 irssi/src/silc/core/silc-servers.c.
1548 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1550 * Assure my_channels statistics cannot go negative in server.
1551 Affected files silcd/server.c, silcd/server_util.c.
1553 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1565 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Added silc_net_localip to return local host's IP address.
1568 Affected file lib/silcutil/silcnet.[ch].
1570 * If key exchange or rekey protocol is active for a connection
1571 parse all packets syncronously since there might be packets
1572 in packet queue that we are not able to process without first
1573 processing packets before them. Affected file silcd/server,
1574 lib/silcclient/client.c.
1576 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1577 whether library should continue processing the packet.
1578 Affected file lib/silccore/silcpacket.h.
1580 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

1608 silc_file_open and silc_file_close. Affected files
1609 lib/silcutil/silcutil.[ch].
1611 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1613 * Resolve the client info when received private message or
1614 channel message for a client which nickname we don't know.
1615 Affected files lib/silcclient/client_prvmsg.c and

1628 Make sure also that USERS command reply does not resolve
1629 twice information. Affected file is
1630 lib/silcclient/command_reply.c.
1632 Make sure that silc_client_get_clients_by_list does not
1633 resolve twice same information.
1635 * Check for valid client->id in the silc_server_free_client_data.
1636 Affected file silcd/server.c.
1638 * Fixed /GETKEY nick@server not to crash if the server entry
1639 is not found. Affected file lib/silcclient/command.c.
1641 * Fixed the silc_server_check_cmode_rights to check the
1642 requested modes correctly. Affected file silcd/command.c.
1644 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1646 * Better checks for non-printable chars in nick added.
1647 Affected file silcd/command.c.
1649 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1651 * Call the silc_server_udpate_servers_by_server in the
1652 primary router that comes back online in the backup resuming
1653 protocol. Otherwise it routes packets wrong. Affected file
1654 silcd/server_util.[ch], silcd/server_backup.c.
1656 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1658 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1659 lib/silcutil/silcbuffmt.[ch].
1661 * Redefined the SILC packet header to include the padding
1662 length. Affected file lib/silccore/silcpacket.[ch].
1664 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1665 length for maximum padding up to 128 bytes). Affected
1666 file lib/silccore/silcpacket.h.
1668 * Removed all backwards support for old 0.5.x MAC thingies.
1669 The SILC packet header change makes it impossible to be
1670 backwards compatible.
1672 * Send the ENDING packet with timeout in the backup resuming
1673 protocol. This is to assure that all routers has connected
1674 to the primary router. Affected file silcd/server_backup.c.
1676 * Changed the RNG to take the first IV from random data. It
1677 used to take it from zero actually. Changed the RNG also
1678 to use /dev/urandom during session. /dev/random is used
1679 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1681 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1683 * Changed the SILC packet header to have the first two bytes
1684 (the packet length) encrypted. Affected files aroung the
1685 code tree, lib/silccore/silcpacket.[ch]. Removed the
1686 SilcPacketCheckDecrypt callback. It is not needed anymore
1687 since the silc_packet_receive_process will determine now
1688 whether the packet is normal or special.
1690 * Implemented the unidirectional MAC keys. Affected files
1691 lib/silcske/silcske.c, silcd/protocol.c and
1692 lib/silcclient/protocol.c.
1694 * Implemented the packet sequence number to the MAC computation.
1695 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1696 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1697 lib/silcclient/protocol.c.
1699 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1701 * Allow backup router to announce servers. All servers
1702 announced by backup router are added to the global list
1703 automatically. Update hte server's socket to our primary
1704 router also when backup router announces a server.
1705 Affected file silcd/packet_receive.c.
1707 * Do not update the client->router in the function
1708 silc_server_udpate_clients_by_server if the client is on
1709 global list. We might fail to find any specific server
1710 for locally connected clients and local cell clients. They
1711 should still use the `from' and not `to' as client->router.
1712 This fixes backup router resuming protocol. Affected file
1713 silcd/server_util.c.
1715 * Decrease channel statistics count only if the channel
1716 deletion worked. Affected files are silcd/server.c and
1717 silcd/server_util.c.
1719 * Added silc_server_update_servers_by_server to update origin
1720 of all server entries. Used during backup router protocol.
1721 Affected files silcd/server_util.[ch], silcd/server.c. and
1722 silcd/backup_router.c.
1724 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1725 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1726 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1727 lib/silccrypt/silchmac.c.
1729 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1731 * Assure that router cannot reroute the same channel message
1732 to the sender. Affected file silcd/packet_receive.c.
1734 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1736 * Made better checks that the channel message is not sent
1737 to the router it came from. Affected file is
1738 silcd/packet_send.c. Fixed memory leak too.
1740 * Announce informations for incoming router connection, but
1741 only after checking if it is replaced by backup router.
1742 Affected file silcd/packet_receive.c.
1744 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1746 * Fixed the backup resuming protocol to work in multiple
1747 router environment. Affected file silcd/server_backup.c.
1749 * Route packet only to one router in the function
1750 silc_server_packet_send_to_channel. Affected file is
1751 silcd/packet_send.c.
1753 * Fixed silc_server_send_notify_dest to set the broadcast
1754 flag. Fixed the silc_server_send_notify_topic to actually
1755 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1756 Affected file silcd/packet_send.c.
1758 * Changed the SFTP Filesystem interface. Changed the
1759 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1760 the filesystem operation function. The SilcSFTPFilesystem
1761 is now a context that is allocated by all filesystem allocation
1762 functions and it already includes the operations structure
1763 and filesystem specific context. It is given as argument
1764 now to the silc_sftp_server_start. This made the interface
1765 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1766 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1768 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1770 * Changed the backup router adding and getting interfaces
1771 in the server. The router that will be replaced by the
1772 specified backup router is now sent as argument. Affected
1773 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1776 * Added silc_net_addr2bin_ne to return the binary form of
1777 the IP address in network byte order. Affected files
1778 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1780 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1782 * Check for existing server ID in silc_server_new_server
1783 and in silc_server_connect_to_router_final and remove the
1784 old entry if it exists. Affected file silcd/packet_receive.c,
1787 * Send the channel message always to only one router, either
1788 in upstream or downstream. Affected file is
1789 silcd/packet_send.c.
1791 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1793 * Wrote the definition of the backup resuming protocol to the
1794 protocol specification.
1796 * Removed one redundant channel key generation from normal
1797 server during joining procedure. Removed one redundant
1798 channel key sending from server to router during joining
1799 procedure. Affected file silcd/command.c.
1801 * Made minor bugfixes to the backup router resuming protocol.
1802 Affected file silcd/server_backup.c, server.c.
1804 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1806 * Added --disable-asm configuration option. Affected files
1807 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1810 * Implemented the backup resuming protocol that is used to
1811 resume the primary router position in the cell after the
1812 primary router comes back online. Affected files
1813 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1814 and silcd/server_util.[ch].
1816 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1818 * Sleep two (2) seconds after sending QUIT command to server.
1819 Affected file lib/silcclient/command.c.
1821 * Assure that if outgoing data buffer is pending do not force
1822 send any data. Affected file silcd/packet_send.c.
1824 * Assure that if outgoing data buffer is pending do not force
1825 send any data. Affected file lib/silcclient/client.c.
1827 * Implemented the backup router support when the primary router
1828 goes down. The servers and routers can now use the backup
1829 router as new primary router without loosing connectivity.
1831 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1833 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1834 in the server to indicate disabled entry. All data read
1835 from the connection will be ignored and no data is sent
1836 for entry that is disabled. Affected files are
1837 silcd/idlist.h, silcd/server.c.
1839 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1841 * Created SFTP client and server test programs in the
1842 lib/silcsftp/tests directory.
1844 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1846 * Implemented memory filesystem (virtual filesystem) for
1847 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1850 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1852 * Implemented the SFTP (SSH File Transfer Protocol) to the
1853 lib/silcsftp. It includes SFTP client and SFTP server
1856 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1858 * Moved lib/silccore/silcprotocol.[ch] to the
1859 lib/silcutil library.
1861 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1862 take variable argument list pointer as argument. Affected
1863 file lib/silcutil/silcbuffmt.[ch].
1865 * Added silc_buffer_set function that is used to set data
1866 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1867 Affected file lib/silcutil/silcbuffer.h.
1869 * Changed various routines in the core library to use the new
1870 silc_buffer_set instead of allocating new buffer only for
1873 * Added 64-bit value formatting and unformatting support to the
1874 silc_buffer_[un]format routines. Affected file is
1875 lib/silcutil/silcbuffmt.[ch].
1877 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1878 to includes/bitmove.h.
1880 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1882 * Fixed channel user mode saving in client library. Affected
1883 file lib/silcclient/command[_reply].c.
1885 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1887 * Defined the file transfer to the SILC Protocol. Added
1888 new packet type SILC_PACKET_FTP and defined File Transfer
1889 Payload. The mandatory file transfer protocol is SFTP
1890 (SSH File Transfer Protocol). Affected file in addition
1891 of the internet draft is lib/silccore/silcpacket.h.
1893 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1894 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1895 is used as part of backup router protocol when the primary
1896 router of the cell is back online and wishes to resume
1897 the position as primary router.
1899 * Redefined the MAC generation keys in the protocol. The
1900 same key is not used anymore in both direction. Both
1901 direction will now use different keys for sending and
1902 receiving. This fixes a potential security flaw. This
1903 change causes incompatibilities in the protocol.
1905 * Redefined also the MAC computation from the packet.
1906 An packet sequence number is now added to the MAC
1907 computation. This prevents possible replay attacks against
1908 the protocol. This change too causes incompatibilities
1911 Added `sequence' field to the SilcPacketContext to hold
1912 the current sequence number for the packet.
1914 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1916 * Added `created' field to the SilcIDListData in the file
1917 silcd/idlist.h to indicate the time when the entry was
1920 * Added `created' field to the SilcChannelEntry too. Affected
1921 file silcd/idlist.h.
1923 * Added `creation_time' aguments to all the announcement functions
1924 in the server. If it is provided then only the entries that
1925 was created after the provided time frame are actually
1926 announced. Affected file silcd/server.[ch].
1928 * The protocol says that the Channel ID's IP address must be
1929 based on the router's IP address. Added check for this in
1930 the silc_server_new_channel when processing incoming New Channel
1931 Payload. Affected file silcd/packet_receive.c.
1933 * Print out the correct version with --version in SILC client.
1934 Affected file irssi/src/silc/core/silc-core.c.
1936 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1938 * Fixed WHOWAS command to check for completnes of the client
1939 entry always, not just when the command is coming from client.
1940 Affected file silcd/command.c.
1942 * Added new function silc_server_packet_queue_purge to purge the
1943 outgoing data queue to the network. After the function returns
1944 it is guaranteed that the outgoing packet queue is empty.
1945 Affected file silcd/packet_send.[ch].
1947 * Purge the outgoing packet queue in the rekey protocol's final
1948 callback to assure that all rekey packets go to the network
1949 before quitting the protocol. Affected file silcd/server.c.
1951 * Added silc_client_packet_queue_parse as similar function as
1952 in server to the client library. The affected file is
1953 lib/silcclient/client.c.
1955 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1957 * Splitted silcd/server.c and created silcd/server_util.[ch]
1958 for utility functions.
1960 * Added new socket flag SILC_SF_DISABLED to indicate that the
1961 connection is open but nothing can be sent to or received from
1962 the connection. Affected file lib/silcutil/silsockconn.[ch].
1963 The checking for disabled socket is checked in the low level
1964 silc_socket_write and silc_socket_read functions.
1966 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1968 * Allow only nicknames and channel names that fits into the
1969 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1971 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * When processing JOIN command reply in server check that if
1974 the channel exists in our global list we'll move it the local
1975 list. Affected file silcd/command_reply.c.
1977 * Fixed the check whether client is joined on the channel already
1978 in JOIN command. Affected file lib/silcclient/command.c.
1980 * Fixed the JOIN command reply to check whether the channel
1981 already exists. Affected file lib/silcclient/command_reply.c.
1983 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1985 * Added silc_ske_status_string to map the SKE error numbers
1986 to readable strings. The affected files are
1987 lib/silcske/silcske[_status].[ch].
1989 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1991 * Do not show the private channels on the WHOIS channel list
1992 as it is not allowed by the protocol. The affected file is
1995 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1997 * Assure that the packet length digged from the actual packet
1998 is something sensible in the silc_packet_decrypt_rest_special
1999 in lib/silccrypt/silcpacket.c.
2001 * Free and NULL the allocated pointer in silc_hmac_alloc if
2002 the HMAC allocation fails. The affected file is
2003 lib/silccrypt/silchmac.c.
2005 * Print the selected security properties to the log files in
2006 the server. Affected file silcd/protocol.c.
2008 * Add SKE's reference counter even if calling the completion
2009 callback manually. Otherwise it goes negative, although it
2010 does not cause any problems. The affected file is
2011 lib/silcske/silcske.c.
2013 * Remove the client entry with short timeout after giving the
2014 KILL command. Affected file lib/silcclient/command.c.
2016 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2017 case all found clients are already disconnected (WHOWAS would
2018 found them) in the server. Affected file silcd/command.c.
2020 * Update the last_receive (time of last data received) to be
2021 updated only when received private or channel message so that
2022 the idle time showed in WHOIS makes more sense.
2024 * Added boolean field `valid' in to the SilcClientEntry in the
2025 client library to indicate whether the entry is valid or not.
2026 This fixes the nickname change bug on channel when changing
2027 the nickname to be same than the old (like nick to Nick) the
2028 nickname formatter doesn't set the new nick anymore to Nick@host.
2029 Affected file lib/silcclient/idlist.[ch].
2031 * Now actually fixed the nickname changing on disconnection.
2032 Added new function silc_change_nick to the Irssi SILC Client.
2033 Affected file irssi/src/silc/core/client_ops.c,
2034 irssi/src/silc/core/silc-nicklist.[ch].
2036 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2038 * Check that the public key exists in the GETKEY command before
2039 trying to encode it. Affected file silcd/command.c.
2041 * Print some notifications on received public keys with GETKEY
2042 command in the Irssi SILC Client. Affected files are
2043 irssi/src/fe-common/silc/module-formats.[ch],
2044 irssi/src/silc/core/client_ops.c.
2046 * Use IDENTIFY command to resolve the server information in the
2047 GETKEY command instead of INFO command. Affected file
2048 lib/silcclient/command.c.
2050 * All command reply functions in the client library now calls
2051 the pending command reply callbacks even if an error has
2052 occurred. The server has done this a long time and now it was
2053 time to move the client library to this as well. Now all
2054 errors can be delivered back to the pending command reply
2055 callbacks if necessary. Affected files are
2056 lib/silcclient/command[_reply].[ch].
2058 * Change the nickname on disconnection back to the username
2059 because in reconnect the server will enforce it to it anyway.
2060 Affected file irssi/src/silc/core/silc-servers.c.
2062 * Fixed a config file parsing bug in the Irssi SILC client.
2063 Affected file irssi/src/silc/core/clientconfig.c.
2065 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2067 * When printing the channel mode on JOIN, verify that the
2068 channel key and channel's HMAC are valid. Affected file
2069 irssi/src/silc/core/client_ops.c.
2071 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2073 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2074 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2075 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2077 * Removed channel key rekey task deleting from the function
2078 silc_server_save_channel_key. Affected file silcd/server.c.
2079 Added explicit timeout task context instead that is used to
2080 delete the task if we are registering a new task before the
2081 new task has elapsed.
2083 * When channel key rekey occurs the client library now saves
2084 the old channel key for a short period of time (10 seconds) and
2085 is able to use it in case some is still sending channel
2086 messages encrypted with the old key after the rekey. Affected
2087 file lib/silcclient/[idlist.h|client_channel.c].
2089 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2091 * Added check to the silc_server_new_id_real to not accept
2092 new ID if it is the sender's own ID. Affected file is
2093 silcd/packet_receive.c.
2095 * Assure that we do not announce ourself or the one we've
2096 sending our announcements when we're router and are announcing
2097 servers to our primary router. Affected file silcd/server.c.
2099 * Fixed silc_server_command_identify_check_client to assemble
2100 correct WHOIS packet. It send corrupted WHOIS packet and
2101 caused problem with router to router connections. Affected
2102 file silcd/command.c.
2104 Fixed also silc_server_command_whois_check the same way
2105 as for the IDENTIFY command.
2107 * Added new SilcIDListStatus to the server in the SilcIDListData
2108 structure. The status now includes the current status of
2109 the entry (like registered, resolved etc.). Affected file
2110 silcd/idlist.[ch]. Defined a bunch of different status types
2111 as well. This replaced the old boolean registered field as well.
2113 Added resolve_cmd_ident field to the SilcClientEntry structure
2114 too so that if the entry is for example being resolved so
2115 another command may attach to the same pending command reply
2116 without requiring to resolve the same entry again. This concept
2117 should optimize the WHOIS and the IDENTIFY resolving under
2118 heavy load by taking away unnecessary resolving for entries
2119 that are being resolved already.
2121 Added support for adding multiple pending commands for one
2122 command idenfier. Affected file silcd/command[_reply].[ch].
2124 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2125 before deleting the data. Otherwise the hash table will have
2126 freed data in comparison functions. Affected file is
2127 silcd/command_reply.c.
2129 * Fixed silc_idlist_replace_client_id to add the new entry to
2130 the cache with NULL nickname. Otherwise there will be invalid
2131 memory as the nickname after the nickname is freed. Affected
2132 file silcd/packet_receive.c.
2134 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2135 saved into wrong slots because the previous number of entries
2136 was not taken into account. Affected file silcd/idlist.c.
2137 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2139 * If we are router and we receive JOIN notify to a channel that
2140 does not have any users then notified client is marked as the
2141 channel founder, as it is it. The affected file is
2142 silcd/packet_receive.c
2144 * Added to the extended hash table API's table_del_*ext functions
2145 the destructor as argument too, so that the caller can decide
2146 which destructor to use or whether to use destructor at all.
2147 Affected file lib/silcutil/silchashtable.[ch].
2149 * Fixed ID Cache purging. It actually deleted the entries from
2150 the hash table after the data was freed. The hash table ended
2151 up comparing freed memory. The affected file is
2152 lib/silccore/silcidcache.c.
2154 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2156 * Fixed Irssi SILC client's KILL command's HELP syntax.
2158 * The USERS command now resolves the detailed user information
2159 if the userinfo field is missing. Affected file is
2160 lib/silcclient/command_reply.c.
2162 * Do not print error in silc_file_read if the read file does
2163 not exist. Just silently return NULL. Affected file is
2164 lib/silcutil/silcutil.c.
2166 * Fixed the silc_log_output to not wine about NULL filename
2167 and to not create some bogus " " filename. Affected file is
2168 lib/silcutil/silclog.c.
2170 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2172 * Fixed various printing bugs on the user interface in the
2173 Irssi SILC Client. Minor changes that were forgotten from
2176 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2178 * Fixed the configure.in.pre and the compilation and distribution
2179 environment to support the new autoconf 2.52. That version is
2180 now required to compile the CVS trunk.
2182 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2184 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2185 to generally parse user@fqdn format strings. Affected file
2186 lib/silcutil/silcutil.c.
2188 * Added nickname_format and nickname_force_format fields to the
2189 SilcClientParams structure. The first one defines the format
2190 for the nicknames that the library will enforce if the receives
2191 multiple same nicknames. The second one is boolean value and
2192 can be used to force the library to always enforce the format
2193 to the nicknames regardles whether there are multiple nicknames
2194 or not. This configurable formatting was employed to flexibly
2195 support accessing multiple nicknames from the user interface.
2196 The userinterface can now set the nicknames to what ever format
2197 they prefer. Affected file lib/silcclient/silcapi.h.
2199 Added function silc_client_nickname_format to the file
2200 lib/silcclient/idlist.c. It performs the nickname formatting.
2202 Added new field `hostname´ to the SilcClientEntry context.
2203 It holds the hostname of the client. Affected file is
2204 lib/silcclient/idlist.h.
2206 * Irssi SILC Client sets the nicknames in nick@hostn format.
2207 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2208 irssi/src/silc/core/silc-core.c.
2210 The WHOIS printing now also shows both the real nickname and
2211 the formatted nickname so that user knows how to access the
2212 user if there are multiple same nicknames cached. Affected
2213 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2214 printing formatting too to take the hostname now as a separate
2215 argument. The Affected file is
2216 irssi/src/fe-common/silc/modules-formats.[ch].
2218 * Changed the silc_client_get_clients_local to accept the formatted
2219 nickname as argument. It accepts the real nickname too but the
2220 formatted nickname can be used to find the true entry from
2221 multiple entries. Affected file lib/silcclient/silcapi.h and
2222 lib/silcclient/idlist.c.
2224 * Added nickname_format_parse field to the SilcClientParams.
2225 It is a callback function provided by the application to parse
2226 the nickname out of the formatted nickname string. The library
2227 calls it to get the nickname from the formatted string. Since
2228 the application generally knows better the format of the nickname
2229 string it parses it instead of the library, even though library
2230 encodes the formatted string. If the callback function is not
2231 provided then the library will use the string as is. The
2232 affected file is lib/silcclient/silcapi.h.
2234 * All the nickname strings passed to the client library in
2235 commands are now expected to be formatted nickname strings.
2236 If the command does not support the formatted nickname string
2237 it will assume that the sent string is the actual nickname.
2238 Affected file lib/silcclient/command.c.
2240 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2242 * Added public key authentication support to OPER and SILCOPER
2243 commands in the client library. Affected file is
2244 lib/silcclient/command.c.
2246 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2248 * Changed the get_auth_methdod client operation to be asynchronous.
2249 It can be async if the application resolves the authentication
2250 method from the server during the negotiation. Added new
2251 SilcGetAuthMeth completion callback that the application will
2252 call after resolving the authentication method.
2254 Added function silc_client_request_authentication_method that
2255 the application can use to resolve the authentication method
2256 from the server. Added also SilcConnectionAuthRequest callback
2257 that the library will call after the server has replied. The
2258 application can call this function if it does not know the
2259 current authentication method.
2261 Affected files are lib/silcclient/client.c and
2262 lib/silcclient/silcapi.h.
2264 * The Irssi SILC client now automatically resolves the authentication
2265 method incase any configuration information is not present (and
2266 currently there never is). The affected file is
2267 irssi/src/silc/core/client_ops.c.
2269 * Fixed public key authentication from the client library.
2270 Affected file lib/silcclient/protocol.c. Changed also the
2271 protocol specification about the public key authentication in
2272 the connection authentication protocol. The actual data to be
2273 signed is now computed with a hash function before signing.
2275 * Fixed the public key authentication from the server as well.
2276 Affected file silcd/protocol.c.
2278 * Removed the mlock()'s from the memory allocation routines.
2279 Affected file lib/silcutil/silcmemory.c. The ./configure does
2280 not check anymore for the mlock(). Affected file is
2283 * Fixed USERS command in server to allow the execution of the
2284 command for private and secret channels if the client sending
2285 the command is on the channel. Affected file silcd/command.c.
2287 * Fixed silc_client_get_clients_local to return the clients
2288 count correctly. It could return wrong value. Affected file
2289 lib/silcclient/idlist.c.
2291 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2293 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2294 types. The assembler optimizations seemed not to like 64-bit
2295 data types. The assmebler optimizations thus are now enabled
2296 also for BSD systems as opposed to only enable them for Linux.
2298 * Do not check for threads at all on BSD systems. Affected
2299 file configure.in.pre.
2301 * Removed -n and -h options from the Irssi SILC Client since
2302 they are not used in silc.
2304 * Fixed the prime generation to assure that the first digit
2305 of the generated random number is not zero since our conversion
2306 routines does not like number strings that starts with zero
2307 digit. If zero digit is seen the random number is regenerated.
2308 This caused some corrupted RSA keys when the zero first digit
2309 was met. Affected file lib/silcmath/silcprimegen.c.
2311 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2313 * Fixed WIN32 configuration in the ./configure script.
2314 Fixed to include xti.h on environments that has it.
2315 Patches by Carsten Ilchmann and andrew.
2317 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2319 * Changed the silc_id_create_client_id to be collision
2320 resistant. It is now assured that there cannot be created
2321 two same client ID's. I suspect that some weird bugs in
2322 the server were actually caused by duplicate Client IDs.
2323 Affected file silcd/serverid.[ch]. A router receiving
2324 new ID now also assures and informs the sending server
2325 if the ID caused collision.
2327 * Changed the silc_id_create_channel_id to also assure that
2328 there are no collisions.
2330 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2332 * Statement about ignoring the Mutual Authentication flag when
2333 performing rekey with PFS was a bit misleading. It is ignored
2334 if it was set in the initial negotiation, it cannot be even
2335 set in the rekey. Fixed in the ke-auth draft. Started the
2336 new versions of the protocol drafts in the doc/.
2338 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2340 * Fixed a bug in silc_client_command_identify_save when saving
2341 new channel information. The channel name was no duplicated
2342 and caused crash on exit. Affected file is
2343 lib/silcclient/command_reply.c.
2345 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2347 * Fixed the getkey command handling in the server. Send just
2348 empty OK reply to the sender if the key could not be fetched
2349 (but everything else was ok, like the key just was not available).
2350 Changed the public key parameter to optional in the protocol
2351 specs so that empty OK reply can be sent. Affected file
2354 Added a message to Irssi SILC client to tell to user if the
2355 server did not return a public key.
2357 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2359 * Fixed a channel key regeneration bug. It registered new
2360 timeout tasks exponentially until all system resources were
2361 used. Affected file silcd/server.c.
2363 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2365 * Added the SILC Document generator to the scripts/silcdoc.
2366 It can be used to generate the Toolkit Reference Manual out
2367 of the source tree. Internally it will also use the RoboDoc
2368 generator now imported in util/robodoc.
2370 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2372 * Added couple of return's in rekey protocol if error orccurred
2373 during the protocol. The execution must be terminated.
2374 Affected file silcd/protocol.c. Also, terminate the protocol
2375 always with timeout.
2377 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2379 * The client's Client ID was created initally from the wrong
2380 nickname (it could have been in format nick@host) in the
2381 silc_server_new_client. Affected file silcd/packet_receive.c
2383 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2385 * Added some SILC_LOG_ERROR's to various error conditions
2386 if client could not be added to ID cache. Affected files
2387 silcd/packet_receive.c and silcd/server.c.
2389 * When client's sock->user_data is freed, NULL also the
2390 client->router and client->connection pointers. Added check
2391 for these pointers being NULL to various places around the
2392 code. Affected file silcd/server.c.
2394 * Added client->data.registered == TRUE checks to various
2395 places around the code to assure that unregistered client's
2396 are not handled when it is not allowed. Affected file
2399 * Added `bool registered' fields to all
2400 silc_idlist_[server|client]_get_* routines to indicate whether
2401 the fetched client needs to be registered or not. Affected
2402 file silcd/idlist.[ch].
2404 * Add your own entry as registered to the ID cache in the
2405 server. Affected file server.c.
2407 * Fixed a bug in silc_server_new_server. The SilcServer was
2408 set as the new server's context instead of SilcServerEntry.
2409 This naturally caused some weird bugs.
2411 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2413 * Do not delete the channel rekey task when adding it
2414 for in silc_server_create_channel_key.
2416 * Changed the silc_server_create_channel_key to return
2417 TRUE or FALSE to indicate the success of the channel key
2420 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2422 * Fixed MSVC++ project files and added missing files to
2423 Makefiles under win32/.
2425 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2427 * Do not add TCP_NODELAY flag if the operating system
2428 does not have it defined. Affected files are
2429 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2431 * Fixed buffer overflow from Irssi SILC Client. Affected
2432 file irssi/src/fe-common/core/themes.c.
2434 * Fixed double free in client library in the file
2435 lib/silcclient/client.c when disconnecting from server.
2437 * Applied double free patch from cras to Irssi SILC client.
2438 Affected files irssi/src/core/[modules/expandos].c
2440 * Fixed the disconnection handling to Irssi SILC Client.
2441 The application must call silc_client_close_connection
2442 in ops->connect client operation in case of failure of
2443 the connection. Affected file is
2444 irssi/src/silc/core/client_ops.c.
2446 * Do not set sock->protocol to NULL in the function
2447 silc_client_close_connection after executing the protocol's
2448 final callback since the sock might not be valid anymore.
2449 Affected file lib/silcclient/client.c.
2451 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2453 * Do not enable SILC_THREADS if the linking with libpthread
2454 did not happen. Affected file configure.in.pre.
2456 * Added notion to protocol specification that server must
2457 verify the sent authentication payload with CMODE when
2458 setting the channel founder key. Implemented it to the
2459 server. Affected file silcd/command.c.
2461 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2463 * Added _EXTRA_DIST SILC distribution variable to the
2464 distributions file. It is used to conditionally add extra
2465 files or directories to the specific distribution. Affected
2466 files ./prepare, Makefile.am.pre and distributions.
2468 Removed the `_' from the start of the distribution names.
2471 * Added README.WIN32 for instructions to compile the Toolkit
2474 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2476 * Fixed a double free in disconnection in the server. Affected
2477 file is silcd/server.c.
2479 * Fixed the lib/silcske/groups.c to work now also with GMP
2480 MP library. The string conversion did not work when using
2481 specific base and the base is indicated in the string as well.
2483 * Created win32/ directory which now includes MSVC++ specific
2484 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2485 It will appear only in the toolkit distribution
2487 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2489 * Changed the key material distribution function in case when
2490 the hash output is too short. The data is now concatenated
2491 a bit differently than it used to. Made the change to the
2492 SKE protocol specification.
2494 * Added better GMP detection to configure.in.pre. A patch
2497 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2499 * Fixed a minor bug in SKE that might cause some problem on
2500 some platforms. Affected file lib/silcske/silcske.c.
2502 * Added the cookie checking for initiator in the SKE. It checks
2503 that the responder returns the sent cookie unmodified. The
2504 affected file is lib/silcske/silcske.c. Added new SKE
2505 error type INVALID_COOKIE that can be sent during the
2506 negotiation. Fixed some memory leaks as well.
2508 * Added the "invalid cookie" error message to Irssi SILC client's
2511 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2513 * Added `task_max' field to the SilcClientParams to indicate
2514 the maximum tasks the scheduler can handle. If set to zero,
2515 default values are used. Affected file lib/silcclient/silcapi.h.
2517 * Fixed memory leaks in silc_client_close_connection. Affected
2518 file lib/silcclient/client.c.
2520 * Added silc_client_del_client_entry to client library to free
2521 all memory of given client entry. Affected file is
2522 lib/silcclient/idlist.[ch].
2524 * Added new functions silc_client_del_channel and
2525 silc_client_del_server to delete channel and server entries.
2526 Affected file lib/silcclient/[silcapi.h/idlist.c].
2528 * Removed silc_client_del_client_by_id from silcapi.h.
2530 * Fixed the INFO command to return the server's own info
2531 correctly when querying by Server ID. Affected file is
2534 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2536 * Removed the non-blocking settings in WIN32 code in the
2537 silc_sock_[read/write] and added SleepEx instead. Affected
2538 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2539 of input data is now checked with FIONREAD and ioctlsocket.
2541 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2543 * Call silc_schedule_task_del_by_context in the
2544 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2545 Affected file lib/silccore/silcprotocol.c.
2547 * Call silc_protocol_cancel for active protocols in the
2548 silc_server_close_connection if the funtion
2549 silc_server_free_sock_user_data has not been called.
2550 Affected file silcd/server.c.
2552 * Generic tasks cannot be deleted using the del_by_fd
2553 task deleting function since generic tasks does not match
2554 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2556 * Added a notion to SILCOPER help file that the SILCOPER works
2557 only on router server, not on normal server.
2559 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2561 * Added for WIN32 support for the new scheduler as well.
2562 Affected file lib/silcutil/win32/silcwin32schedule.c.
2564 * Fixed the SHA1 implementation to work on various platforms.
2566 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2568 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2569 API. It is part of the scheduler now. Everything else is
2570 as previously but some functions has changed their names.
2571 Checkout the lib/silcutil/silcschedule.h for the interface.
2572 Updated all applications to use the new interface. Affected
2573 files are lib/silcutil/silcschedule.[ch].
2575 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2577 * Found a bug in the SKE implementation. The HASH value,
2578 specified by the protocol, was not computed correctly. The
2579 public key of the responder was not added to the computation
2580 even though it is mandatory. Affected file lib/silcske/silcske.c.
2581 This unfortunately causes incompatibilities with older
2582 clients and servers.
2584 * Added WIN32 specific network init and uninit functions:
2585 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2586 the Winsock2. Affected file lib/silcutil/silcnet.h and
2587 lib/silcutil/win32/silcwin32net.c.
2589 * Set the socket always to nonblocking mode on WIN32 after
2590 reading data or writing data. Affected file is
2591 lib/silcutil/win32/silcwin32sockconn.c.
2593 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2595 * Fixed various compilation problems under WIN32. Affected
2596 files lib/silcutil/win32/silcwin32thread.c and
2597 lib/silcutil/win32/silcwin32schedule.c.
2599 * Removed all _internal.h #includes from public header
2600 files. Internal headers must never be included from
2603 Removed also the lib/silcske/payload_internal.h file.
2605 * All include files that may be needed (public and some others
2606 included by the public headers) by application developers are
2607 now copied to the ./includes directory. It does not copy any
2608 internal headers. Affected file Makefile.defines.pre and all
2609 Makefile.am's under lib/ and subdirs.
2611 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2613 * Do not change the ~/.silc directory's permissions automatically.
2614 Affected file irssi/src/silc/core/clientutil.c.
2616 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2618 * Do not cancel the protocol in silc_server_close_connection
2619 it might cause recursion. Now cancelled in the function
2620 silc_server_free_sock_user_data. Affected file silcd/server.c.
2622 * Fixed the silc_server_remove_clients_by_server to regenerate
2623 the channel keys correctly finally. Added also new function
2624 silc_server_remove_clients_channels to actually do it.
2625 Affected file silcd/server.c.
2627 * Fixed the silc_server_new_channel to not crash by giving
2628 wrong router to the new channel. Affected file is
2629 silcd/packet_receive.c.
2631 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2633 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2634 which is given as argument to the silc_client_alloc now.
2635 It can be used to configure the client and set various parameters
2636 that affect the function of the client.
2638 * The USERS command in server did not check whether the channel
2639 is private or secret. Affected file silcd/command.c.
2641 * Added new argument to the USERS command in protocol specification.
2642 The USERS command now can take the channel name as argument
2643 as well. Added support for this in client and server and
2644 updated the protocol specs.
2646 * Completed the GETKEY command in client. It can be now used
2647 to fetch also servers public key not only some clients.
2648 Affected files lib/silcclient/command[_reply].c.
2650 * Added silc_client_get_server to return server entry by the
2651 server name. Affected files lib/silcclient/silcapi.h and
2654 * Redefined the IDENTIFY command in protocol specification to be
2655 more generic. It now can be used to query information about
2656 any entity in the SILC Network, including clients, servers and
2657 channels. The query may be based either the entity's name
2658 or the ID. Added support for this in both client and server.
2660 Affected files silcd/command.c and lib/silcclient/command.c
2661 and command_reply.c.
2663 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2664 the _from_client and _from_server functions. Affected file
2667 * Added silc_client_get_channel_by_id_resolve to the file
2668 lib/silcclient/silcapi.h to resolve channel information by
2669 its ID. Added also silc_client_get_channel_by_id that
2670 does not resolve it from the server.
2672 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2674 * Added SilcServerEntry context into the client library
2675 to represent one server. The INFO command now allocates
2676 these to save the resolved server info. For now on the
2677 client library will also keep information about servers,
2678 connected and resolved with INFO.
2680 The INFO command now allocates the SilcServerEntry context
2681 and saves the server info there. The COMMAND_REPLY in
2682 the INFO now returns the parameters to application in
2683 same order as defined in the protocol specification.
2685 The entries are cached in the client->server_cache.
2687 * The INFO command is now issued after received the Client ID
2688 from the server. Affected file lib/silcclient/client.c.
2690 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2691 to the application as the mode changer might be server.
2692 It is guaranteed that NULL is not returned anymore to the
2693 application. Affected file lib/silcclient/client_notify.c.
2695 The ID Type is now also passed to the application so that
2696 it can check whether the returned entry is SilcClientEntry
2699 Added new function silc_client_get_server_by_id to return
2700 the server entry by ID. Affected files are the
2701 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2703 * Do not create the channel in the Irssi SILC Client when issuing
2704 the JOIN command but when received the sucessful JOIN command
2705 reply. Otherwise the channel might get created even though we
2706 could not join it. The Affected file is
2707 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2709 * Fixed a channel joining bug in router. The router must also
2710 check the channel modes, invite and ban lists etc. when serving
2711 the JOIN command sent by normal server. Affected file is
2712 silcd/command.c. The router now resolves the client's
2713 information from the server who sent the JOIN command if it
2714 does not know it, and processes the JOIN command only after
2717 * Changed the SilcCommandCb to take new argument; void *context2.
2718 Affected file lib/silccore/silccommand.h
2720 The second argument in the command callbacks in the server now
2721 includes the SilcServerCommandReplyContext if the command was
2722 called as pending command callback from the command reply.
2723 Otherwise it is NULL. When called as pending the status of the
2724 command reply will be checked and if it was erronous the
2725 error will be sent to the original sender of the command.
2726 This way the client always receives the error messages even
2727 though the server was actually the one who received the error
2728 when it resent the command to router, for example. Affected
2729 files silcd/command[_reply].[ch].
2731 * Fixed sending WHOWAS command's error message to client if
2732 the requested client could not be found. It was missing.
2735 * Changed the CMODE and CUMODE commands reply arguments in the
2736 protocol specification. The Channel ID is now sent in both
2737 of the commands to identify the channel. Implemented this
2738 new feature to the client and server. Affected files
2739 lib/silcclient/command_reply.c and silcd/command.c.
2741 * Made better checks for invite and ban lists in the JOIN
2742 command in server. Affected file silcd/command.c.
2744 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2746 * The server now performs the incoming host IP/DNS lookup
2747 using the silc_socket_host_lookup and thus does not block
2748 the server anymore. Affected file silcd/server.c.
2750 * Completed the multi-thread support for SILC Scheduler in
2751 the lib/silcutil/silcschedule.c.
2753 * Fixed the configure.in.pre to detect the pthread correctly
2756 * Fixed a deadlock in silc_task_queue_wakeup in the file
2757 lib/silcutil/silctask.c.
2759 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2761 * Added new function silc_schedule_wakeup that is used in
2762 multi-threaded environment to wakeup the main thread's
2763 schduler. It needs to be used when a thread adds a new task
2764 or removes a task from task queues. After waking up, the
2765 scheduler will detect the task queue changes. If threads
2766 support is not compiled in this function has no effect.
2767 Implemented the wakeup mechanism to both Unix and WIN32
2768 systems. Affected files are lib/silcutil/silcschedule.[ch],
2769 lib/silcutil/unix/silcunixschedule.c and the
2770 lib/silcutil/win32/silcwin32schedule.c.
2772 * Added new function silc_task_queue_wakeup to wakeup the
2773 scheduler by the specified task queue. Affected file
2774 lib/silcutil/silctask.[ch].
2776 * The silc_socket_host_lookup_start now wakes up the scheduler
2777 after adding the timeout task. Affected file is
2778 lib/silcutil/silcsockconn.c.
2780 * The silc_socket_host_lookup is synchronous now if the threads
2781 support is not compiled in. However, the callback is still
2782 called asyncronously through the scheduler, anyway. Affected
2783 file lib/silcutil/silcsockconn.c.
2785 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2787 * Added new function silc_socket_host_lookup to perform
2788 asynchronous IP and FQDN lookups for the socket connection.
2789 Affected files lib/silcutil/silcsockconn.[ch].
2791 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2793 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2794 that may or may not compile the mutex support in.
2796 Changed the silc_mutex_alloc interface. It allocates the
2797 mutex now to the sent pointer and returns TRUE or FALSE.
2799 Affected file lib/silcutil/silcmutex.h.
2801 * Wrote the SILC Task Queue interface to support multi-threads.
2802 Affected file lib/silcutil/silctask.[ch].
2804 * Wrote the SILC Scheduler to support multi-threads. Affected
2805 file lib/silcutil/silcschedule.c.
2807 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2809 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2810 in lib/silcutil/win32/.
2812 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2814 * Defined SILC Mutex API and SILC Thread API and implemented
2815 them for Unix. Affected files are
2816 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2817 lib/silcutil/unix/silcunixmutex.c and
2818 lib/silcutil/unix/silcunixthread.c.
2820 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2822 * Fixed the silc_server_remove_clients_by_server's channel
2823 key re-generation. The hash table handling was incorrect
2824 and would not work with many channels. Affected file is
2827 * Fixed some memory leaks around the server code.
2829 * Rewrote the silc_server_get_users_on_channel to support IPv6
2830 based Client ID's. Affected file silcd/server.c.
2832 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2833 specification. However, a separate document must be written
2834 to define the detailed signing procedure and the payload
2835 associated with the flag. Defined the flag to the
2836 lib/silccore/silcchannel.h as well.
2838 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2840 * Changed the dynamic tables to static size tables in the
2841 lib/silccrypt/silchmac.c.
2843 * Removed GCC dependencies from the code. A patch by cras.
2845 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2847 * Do not show the error "Error receiving packet bla bla"
2848 in server if it really was not an error (-2 means that reading
2849 is pending). Affected file silcd/server.c.
2851 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2853 * Fixed a possible crash in silc_server_remove_clients_by_server
2854 in silcd/server.c. Fixed there also some memory leaks.
2856 * Fixed the silc_idlist_replace_client_id. It could replace
2857 wrong key in the hash table. Affected file silcd/idlist.c.
2859 * Do not check whether there are global users on the channel
2860 if the channel->global_users is FALSE. Affected functions
2861 silc_server_remove_from_one_channel and
2862 silc_server_remove_from_channels in silcd/server.c. Also,
2863 do not check if the removed client is local as we can be
2864 sure that global client was not removed from the channel
2865 and checking for global users is not needed.
2867 * The silc_server_remove_clients_by_server now re-generates
2868 the channel keys correctly for those channels that had
2869 clients removed from them. Affected file silcd/server.c.
2871 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2873 * Found the reason of random crashes in the server. We weren't
2874 ignoring the SIGPIPE signal (which can be sent in write())
2875 and it crashed the server. Affected file silcd/silcd.c.
2877 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2879 * Assure that sock->user_data is not NULL in the function
2880 silc_server_packet_send in silcd/packet_send.c.
2882 * Disconnect the remote connection if it could not be added
2883 to any ID lists in the server. The affected file is
2886 * Check in silc_server_packet_send[_real/dest] that the
2887 socket is not disconnecting and ignore the data if it is.
2888 Affected file silcd/packet_send.c.
2890 * Define inline to __inline on native WIN32 compilation.
2891 Affected file includes/silcwin32.h.
2893 * Added some explicit type casts for inline code since MSVC
2894 require them. Affected files lib/silcutil/silcbuffer.h,
2895 lib/trq/silcdlist.h and lib/trq/silclist.h.
2897 * Print warning in log files from now on if the packet
2898 decryption fails. Affected file silcd/server.c.
2900 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2902 * Changed the `say' client operation's interface to accept
2903 new `type' argument to indicate the type of the message sent
2904 by the library. The application may filter the library's
2905 messages according the type. The affected file is the
2906 lib/silcclient/silcapi.h.
2908 * Added two new functions to lib/silcclient/silcapi.h:
2909 silc_client_del_client and silc_client_del_client_by_id.
2910 Affected file lib/silcclient/idlist.c.
2912 * Moved the clientincludes.h from includes/ to silc/ and
2913 serverincludes.h from includes/ to silcd/.
2915 * The modes for the CMODE and CUMODE are now passed as
2916 uint32 for application with COMMAND_REPLY. The affected
2917 file is lib/silcclient/command_reply.c.
2919 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2921 * /WHOIS without arguments shows client's own information.
2922 Affected file lib/silcclient/command.c.
2924 * Changed PING to not accept any arguments. The specs
2925 says that client can ping only the connected server so
2926 requiring an argument is not needed. Affected file is
2927 lib/silcclient/command.c.
2929 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2931 * Fixed a fatal bug in private message sending and reception
2932 encryption and decryption when using private message keys.
2933 The implementation was incorrect and did not follow the
2934 specification. It causd that some of the message were
2935 lost since it did not use the sending and receiving keys
2936 as the protocol suggests. This has been fixed and will cause
2937 incompatibilities with older clients when sending private
2938 message encrypted with private message keys. Affected files
2939 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2940 and various other in Irssi SILC Client.
2942 Added `responder' boolean argument to the functions
2943 silc_client_add_private_message_key[_ske] to indicate when
2944 the key is added as responder or initiator of the key
2947 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2949 * Removed the silc_ske_check_version function and created
2950 a SilcSKECheckVersion callback. Added also a function
2951 silc_ske_set_callbacks that is now used to set all SKE
2952 callbacks. The callback functions are not given to
2953 the SKE functions anymore, but this function is used to
2956 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2958 * Added `silc_version' argument to the silc_client_alloc
2959 to define the version of the application for the library.
2960 The library will use the version string to compare it
2961 against the remote host's (usually a server) version
2962 string. Affected file lib/silcclient/silcapi.h
2964 * Added the KE protocol context to Key Agreement context
2965 in client library so that we can abort the SKE if it
2966 is in process when we get timeout. Affected file is
2967 lib/silcclient/client_keyagr.c.
2969 * Do not resolve the client ID forever if it returns in the
2970 first time that such client does not exist. This was done
2971 for example with private message. Affected file is
2972 lib/silcclient/client_prvmsg.c.
2974 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2976 * Do not add regex.h for WIN32. The affected file
2977 includes/silcincludes.h.
2979 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2980 not work yet 100%. It generates the DLL's automatically
2981 when compiling with --with-win32 under cygwin.
2983 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2985 * lib/contrib/regex.c is not compiled on WIN32.
2987 * Added silc_net_get_socket_opt function to the
2988 lib/silcutil/silcnet.h.
2990 * Added includes/silcwin32.h for WIN32 specific includes
2993 * Do not use ptime structure or any of the posix process
2994 functions on WIN32 in lib/silccrypt/silrng.c.
2996 * Added silc_gettimeofday to provide generic function
2997 for struct timeval on all platforms. Added the function
2998 to lib/silcutil/silcutil.h.
3000 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3002 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3003 library as they clearly belong there. As a plus side we
3004 can make the actual socket connection routines platform
3007 Added also new generic function silc_socket_read and
3008 silc_socket_write (that used to be silc_packet_[read/write].
3009 The implementation of these are platform specific.
3011 * Added WIN32 specific routines of silc_socket_[read/write]
3012 to lib/silcutil/win32/silcwin32sockconn.c.
3014 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3016 * Added preliminary support for native WIN32 compilation under
3017 cygwin (using the -mno-cygwin option for GCC) to the
3018 ./configure.in.pre. The --with-win32 now prepares the
3019 compilation for native WIN32.
3021 * Rewrote the SILC Scheduler interface in the file
3022 lib/silcutil/silcschedule.h. The scheduler is now context
3023 based and does not have anymore any global static scheduler.
3024 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3025 and created lib/silcutil/win32 directory for WIN32 based
3028 * Added Unix specific network routines to the
3029 lib/silcutil/unix/silcunixnet.c and the old
3030 lib/silcutil/silcnet.c includes now only generic routines.
3032 Added WIN32 specific network routines to the
3033 lib/silcutil/win32/silcwin32net.c.
3035 * Added Unix specific utility functions from the
3036 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3038 * Added WIN32 SILC Scheduler to the file
3039 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3042 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3044 * Do not handle JOIN notify in the server if the target client
3045 is not registered (idata->registered == FALSE). The affected
3046 file is silcd/packet_receive.c.
3048 * Update the nickrec->founder in event_cumode in the Irssi SILC
3049 client. Affected file irssi/src/silc/core/silc-channels.c.
3051 * Fixed the CUMODE_CHANGE notify handling in the server when
3052 server and router are announcing their clients on channels.
3053 Now the mode changes are saved and notified correctly. The
3054 affected file is /silcd/packet_receive.c.
3056 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3057 They really did not replace the cache entry in the ID Cache.
3058 Now they do that. Affected file silcd/idlist.c.
3060 * Fixed the KICK notify handling in the Irssi SILC client to
3061 update the channel records so that the kicked client does not
3062 appear to be on the channel. The affected file is
3063 irssi/src/silc/core/silc-channels.c.
3065 * Always update the conn->current_channel when executing command
3066 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3068 * Fixed the KILL notify handling in Irssi SILC client to remove
3069 the killed client on all channels.
3071 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3073 * Fixed the silc_parse_command_line to remove extra spaces
3074 from the start and end of the arguments. Affected file is
3075 lib/silcutil/silcutil.c.
3077 * Cancel and free any active protocol in the function
3078 silc_server_close_connection. Affected file silcd/server.c.
3080 * Cancel and free any active protocol in the function
3081 silc_client_close_connction. Affected file is
3082 lib/silcclient/client.c.
3084 * Do not execute the KILL command for clients that are in
3085 history (ie. they are not in the network). Affected file is
3088 * Fixed KILL notify handling, client does not crash anymore.
3089 Affected file irssi/src/silc/core/silc-channels.c.
3091 * Reduced the default packet buffer size from 2048 to 1024 in
3092 lib/silccore/silcpacket.c.
3094 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3095 counter to the SKE context that is incresed when the SKE library
3096 performs async operation outside the library. If the outside
3097 process frees the SKE context and FREED status will be set
3098 and the library will detect after the sync operation that the
3099 libary is freed. The affected files are
3100 lib/silcske/silcske[_status].[ch].
3102 * Resolve the client entry information in the function
3103 silc_client_channel_message to assure that NULL pointer is not
3104 passed as client entry to the application. */
3106 * Fixed the task timeout calculation to assure that there is
3107 never negative timeouts. The affected file is
3108 lib/silcutil/silcschedule.c.
3110 * Fixed the channel user mode notification sending in server.
3111 It was sent point-to-point to the router (or to server by router)
3112 but it needs to be destined to a channel. The routines now
3113 supports sending the channel user mode notifys to the channels
3114 when announcing clients and channels. Affected files are
3115 silcd/server.c and silcd/packet_receive.c.
3117 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3118 It did not actually replace the old channel entry in the cache.
3119 Affected file lib/silcclient/client_notify.c.
3121 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3123 * Fixed a possible crash in silc_packet_send_prepare. It now
3124 assures always that there is enough space in the buffer and
3125 at the tail area of the buffer (for MAC).
3127 Fixed the inbound buffer reallocation in silc_packet_read.
3128 It was old code and did not handle the reallocation correctly.
3131 The affected file is lib/silccore/silcpacket.c.
3133 * Fixed buffer overflow in silc_parse_nickname in the file
3134 lib/silcutil/silcutil.c.
3136 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3138 * make install generates new server keys only if there is not
3141 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3143 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3144 Added check that if the NOREPLY is set then we will not send
3145 the away message. This avoids infinite loop of away messages
3146 if both clients are away. The affected file is
3147 lib/silcclient/client_prvmsg.c.
3149 * Fixed client crash if /NICK was given without arguments.
3150 Affected file lib/silcclient/command.c.
3152 * Server does not send the invite list in INVITE command back
3153 to the client if the list was not altered. Added this notion
3154 to the protocol spec as well. Affected file silcd/command.c.
3156 Fixed possible crash in INVITE command by checking the
3157 value of silc_server_get_client_route command.
3159 * Fixed the INVITE notify type handling. The arguments are now
3160 taken in correct order and client does not crash. The affected
3161 file is irssi/src/silc/core/silc-channels.c.
3163 Removed the "Inviting xxx to channel" message from the
3164 client library away and let the application handle it.
3165 Affected file lib/silcclient/command.c. Added that message
3166 to Irssi SILC client's message formats.
3168 * Fixed CMODE command crash in client. It now checks the
3169 amount of arguments correctly and does not crash. The affected
3170 file is lib/silcclient/command.c.
3172 * Do not create new channel automatically in silc_channels_join
3173 but check whether the channel by that name already exists.
3174 Affected file irssi/silc/core/silc-channels.c.
3176 * Do not send the SERVER_SIGNOFF to router if the disconnected
3177 entity was the router. Affected file silcd/server.c.
3179 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3180 SILC client as it was missing from there.
3182 Added the handling of the KICK notify to the Irssi SILC client
3183 as it was missing. Added "you have been kicked" message to
3184 Irssi SILC client's message modules formats.
3186 Added the handing of the KILL notify to the Irssi SILC client
3187 as it was missing. Added the kill message module formats
3190 The affected file is irssi/src/silc/core/silc-channels.c.
3192 * The router did not save the channel mode the server announced.
3193 Affected file silcd/packet_receive.c.
3195 * Fixed a possible crash in INFO command in server. If the
3196 server did not provide the server info it crashed. Affected
3197 file silcd/command.c.
3199 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3201 * Fixed the GETKEY command in the server to check also the
3202 global list. Otherwise the GETKEY would not work correctly
3203 in normal SILC server. Affected file silcd/command.c.
3205 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3207 * Fixed GETKEY crash, it crashed if the command did not succseed.
3209 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3211 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3212 is now real and not just an macro interface to GMP.
3214 Removed the entire GMP from the source tree and imported new
3215 NSS MPI library instead. Reason for removing GMP is that it is
3216 extremely large and compiles extremely slow. The NSS MPI
3217 is only a few files and compiles in less than 10 seconds.
3218 The speed is also about the same as GMP. The MPI is imported
3219 to lib/silcmath/mpi.
3221 If the system has GMP installed we will still use the GMP.
3222 If it is not then the NSS MPI will be compiled.
3224 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3226 * Merged a long nickname (127 characters long) crash bugfix from
3227 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3229 * Merged a freed memory reference bugfix from Irssi CVS tree.
3230 Affected file irssi/src/core/commands.c.
3232 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3234 * Added the server's public key sving and verification to the
3235 server when performing the SKE. This was missing and the
3236 remote server's (or router's) public key was accepted without
3237 checking whether we have it previously or trust it at all.
3238 Affected file silcd/protocol.c.
3240 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3242 * Check in the silc_server_timeout_remote if protocol is active
3243 and make sure that the protocol's final callback is called so
3244 that all memory if freed. Affected file silcd/server.c.
3246 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3248 * silc_server_whois_send_reply crashed the server if the nickname
3249 was 127 characters long. Affected file silcd/command.c.
3251 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3253 * Added sanity check to the silc_server_new_client. If the hostname
3254 is provided inside username then check that the provided hostname
3255 really is the same as the resolved one. If the hostname was not
3256 resolved then check it from the public key. Affected file is
3257 silcd/packet_receive.c.
3259 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3260 if the server disconnected us and the connection is not valid
3261 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3263 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3264 the library to the lib/silcutil/silcutil.[ch].
3266 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3268 * Close log file after open. Affected file
3269 lib/silcutil/silclog.c.
3271 * Check whether sock == NULL in silc_client_send_packet and return
3272 if it is. Affected file lib/silcclient/silcclient.c.
3274 * Check rec->entry == NULL in the Irssi SILC Client before
3275 sending the channel message. Affecte file is
3276 irssi/src/silc/core/silc-servers.c.
3278 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3280 * Merged a splitted window bugfix from Irssi CVS tree. The
3281 affected file is irssi/src/fe-text/textbuffer-view.c.
3283 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3284 It did not print nickname.
3286 * Improved the distributions system a bit.
3288 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3290 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3291 irssi/src/fe-text/gui-window.c.
3293 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3294 to in-active server. The affected file is
3295 irssi/src/silc/core/client_ops.c.
3297 * Resolve the client in USERS command reply if the entry does
3298 not have username resolved. The affected file is
3299 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3300 command to WHOIS command to really resolve stuff. The USERS
3301 is not used any more in any critical section so WHOIS can
3302 be used even though it might be slower than IDENTIFY.
3304 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3307 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3309 * Changed the protocol API a bit more consistent in the
3310 lib/silccore/silcprotocol.[ch].
3312 * Changed the following headers to ROBODoc format:
3314 lib/silccore/silcpayload.h
3315 lib/silccore/silcprotocol.h
3316 lib/silccore/silcsockconn.h
3318 All core library headers are now formatted.
3320 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3322 * Fixed a bug in Irssi SILC client; do not show that you are
3323 server/router operator if you really are not. Affected file is
3324 irssi/src/silc/core/client_ops.c.
3326 * Renamed silc_command_free_payload to silc_command_payload_free.
3327 Affected file lib/silccore/silccommand.h
3329 * Added silcmath.h to include the prototoypes of various routines
3330 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3333 * Changed the following headers to ROBODoc format:
3335 lib/silccore/silcchannel.h
3336 lib/silccore/silccommand.h
3337 lib/silccore/silcid.h
3338 lib/silccore/silcidcache.h
3339 lib/silccore/silcmode.h
3340 lib/silccore/silcnotify.h
3341 lib/silccore/silcpacket.h
3342 lib/silcmath/silcmath.h
3344 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3346 * Added checking to the server code not to start the server if
3347 ciphers and stuff are not configured properly. Affected files
3348 silcd/serverconfig.[h] and silcd/server.c.
3350 * Changed the layout of the header files of the public interfaces
3351 in the SILC libraries. The new layout supports ROBODoc
3352 documentation tool (and some others) so that it is easy to create
3353 a library reference manual. All the other headers and source
3354 code must still follow the CodingStyle document. Also source
3355 code must not include these ROBODoc stuffs, only the headers.
3356 Furthermore, all public interface headers must now be named
3357 by using `silc' prefix, example: silcapi.h, silccipher.h.
3358 Some files were renamed due to this. All the other headers
3359 must not be used as public interfaces. I will update the
3360 CodingStyle document later. Changed following headers, so far:
3362 lib/silcclient/silcapi.h
3363 lib/silccore/silcauth.h
3364 lib/silccore/silcprivate.h
3365 lib/silccrypt/silcdh.h
3367 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3371 * Removed silc_client_packet_send_flush from the client library
3372 as it is not needed. Affected file lib/silcclient/client.[ch].
3374 * Added printing of message of unresolved authentication method
3375 to the Irssi SILC client. Added it to the module formats.
3376 Removed the same message from the client library.
3378 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Added new distribution feature, DISTLABEL. Every distribution
3381 can define own preprocessor label that can be used in the
3382 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3383 file distributions, acconfig.h.pre and prepare.
3385 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3387 * Added Makefile.defines_int to include the actual definitions
3388 for Makefile.defines.in. Tested the new distribution system,
3389 created distributions and tested installation.
3391 * Added AWAY message printing to the Irssi SILC client. Added
3392 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3394 * Added SCONNECT command to call the SILC's CONNECT command.
3395 Cannot use CONNECT directly since Irssi uses that internally.
3396 Affected file irssi/src/silc/core/silc-servers.c.
3398 Added ACTION local command. It is same as ME command but takes
3399 the channel as mandatory argument.
3401 Rewrote some of the Irssi's help files to suite for SILC
3404 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3406 * Added Makefile.defines[.in] that should for now on be included
3407 in all Makefile.am file in the source tree. That file includes
3408 all common compilation definitions for SILC source tree.
3410 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3412 * Minor changes to the ./prepare script to change the package
3413 name according the distribution name to the configure.in.
3415 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3417 * Created new distribution system. Added file `distributions'
3418 that defines all the distributions that can be created out of
3419 the SILC source tree. The ./prepare script now reads that
3420 file to determine how to prepare the distributions. The
3421 first argument to the ./prepare is the name of the distribution
3422 and second is the version of the distribution. If given
3423 without arguments it creates the default (toolkit) distribution
3424 with the default version (defined in ./prepare).
3426 All Makefile.am files that are subject to the distributions
3427 are now named as Makefile.am.pre. These are ./Makefile.am
3428 and lib/Makefile.am. Others may be changed later.
3430 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3432 * Added invite list, ban list, some key management and connection
3433 error message printing to module formats in the Irssi SILC client.
3435 * Added new silc_client_set_away_message to set the away message
3436 that is back to the person who sent private message. The
3437 affected file lib/silcclient/silcapi.h and the
3438 lib/silcclient/client_prvmsg.c.
3440 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3442 * Fixed the private message sending in the Irssi SILC client,
3443 added local command KEY to the Irssi SILC client.
3445 Added key management and key agreement message formats to the
3446 irssi/src/fe-common/silc/module-formats.[ch].
3448 Added USERS (alias WHO) printing, server/router operator
3449 indication and LIST command printing to the module formats.
3451 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3453 * Fixed channel joining notify handling, cumode notify handling
3454 from Irssi SILC client.
3456 * Added SILC specific module-formats to the Irssi SILC client so
3457 that SILC specific message hilighting, colors etc is possible.
3458 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3460 Added channel mode, channel user mode, actions, notices,
3461 whois and whowas printing to the the module-formats.c.
3463 * Fixed a bug in channel deletion in the server. The channel
3464 is not left to the cache even if the channel founder auth mode
3465 is set when there are no users anymore on the channel. Affected
3466 file silcd/server.c.
3468 * The silc_net_localhost now resolves the entire hostname including
3469 the domain name. Affected file lib/silcutil/silcnet.c.
3471 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3473 * Changed the ask_passphrase client operation to be ascynchronous.
3474 It has now a completion callback and a context that the
3475 application must call after it has got the passphrase from
3476 the user. Affected files lib/silcclient/silcapi.h,
3477 lib/silcclient/protocol.c, lib/silcclient/command.c and
3480 Added SilcAskPassphrase callback that the application calls
3481 to deliver the passphrase to the library.
3483 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3484 The public key verification and especially a certificate
3485 verification is asynchronous procedure.
3487 Added new SILC_SKE_STATUS_PENDING status to indicate the
3488 request is pending and a callback will be called to finalize
3491 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3492 indicate that remote end did not send its public key (or
3493 certificate), even though we require it. Added check for this
3494 condition in the SKE. This was a security bug, now fixed.
3496 Defined new SilcSKEVerifyCbCompletion callback that is called
3497 when the verification process is completed.
3499 The affected files lib/silcske/silcske_status.h and
3500 lib/silcske/silcske.[ch].
3502 * Changed the verify_public_key client operation to be async
3503 as well. Defined SilcVerifyPublicKey callback that is used to
3504 indicate the success of the public key verification process.
3506 Changed the server and client to use the new async client
3509 * Changed the Irssi SILC client's internal scheduler to be called
3510 twice as many times as it used to be. As a result the client
3511 should be a bit faster now. Affected file is
3512 irssi/src/silc/core/silc-core.c.
3514 * Added support to Irssi SILC client of asynchronous public key
3515 verification and passphrase inquiry. Affected file is
3516 irssi/src/silc/core/silc-core.c.
3518 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3520 * Do not say "You have left channel %s" in client library.
3521 Moved it to the application. Affected files are
3522 lib/silcclient/command.c and silc/client_ops.c.
3524 * Fixed silc_client_get_clients. Command context was not
3525 duplicated and was freed memory in the callback. Affected
3526 file lib/silcclient/idlist.c.
3528 * Do not say "you are now talking..." on JOIN command in the
3529 client library. The appliation must handle it.
3531 * Do not say ".. changed topic to" in command reply in the
3532 client libary. The application must handle it.
3534 * Fixed TOPIC command sending in the client library.
3536 * Fixed a memory leak in silc_client_command_free in the file
3537 lib/silcclient/command.c.
3539 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3541 * Imported a modified version of Irssi client to the source tree.
3542 The Irssi will be used to create a new client called
3543 Irssi SILC. Imported to irssi/.
3545 Added silc_core_init_finish function to the Irssi. Affected
3546 file irssi/configure.in.
3548 A lot changes in the Makefile.ams around the irssi tree.
3550 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3552 * Do not rehash if the new size is same as the old size of the
3553 hash table, in the silc_hash_table_rehash*. The affected file
3554 lib/silcutil/silchashtable.c.
3556 * Replaced hash_table_del_by_context calls from the server
3557 (when channel->user_list and client->channels) to the
3558 hash_table_del as it is sufficient and faster.
3560 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3562 * Added silc_hash_table_list, silc_hash_table_get and the
3563 SilcHashTableList structure to provide an alternative way to
3564 traverse the hash table. The affected files are
3565 lib/silcutil/silchashtable.[ch].
3567 * Changed the server's idlist routines to use the hash table
3568 routines to optimize the code.
3570 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3572 * Replaced the client entry's `channel' list and channel entry's
3573 `user_list' list to hash tables for optimized lookup. Changed
3574 the code to use the hash table interface around the code.
3575 Affected file lib/silcd/idlist.[ch].
3577 * Added `auto_rehash' boolean argument to the function
3578 silc_hash_table_alloc to indicate whether the hash table should
3579 auto-rehash when it thinks is appropriate time. It will
3580 increase the hash table size if the there is twice as much
3581 entries in the table than the size of the table, and will
3582 decrease the size if there are twice as less entries than
3583 the size of the table.
3585 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3587 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3589 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * silc_idcache_purge_by_context deletes the entry now by context
3592 as it is supposed to do. Affected file lib/silccore/idcache.c.
3594 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3595 client is not anymore valid (WHOWAS givens the info) and not
3596 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3598 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3600 * Removed the `data' and `data_len' arguments from the ID Cache
3601 interfaces and added `name' argument. ID Cache does not handle
3602 anymore the binary data only a names associated with given ID.
3604 * When hashing a Client ID with silc_hash_id the entire ID is
3605 not hashed anymore, instead only the hash of the Client ID is
3606 hashed. This way we can access the Client ID from the cache
3607 with Client ID but with the hash of the ID (which is a hash of
3608 the nickname) as well without any difference in performance.
3610 Added also silc_idcache_find_by_id_one_ext to do one on one
3611 searching when we have the actual ID. Added also function
3612 silc_hash_client_id_compare. The affected files are
3613 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3615 * When hashing the name associated with a ID it is always done
3616 in lowercase. This way we can access the cache without worrying
3617 about case-sensitivity, even though, for example nicknames are
3620 * Fixed a bug in server with channel message sending. It put
3621 wrong ID type as destination ID. The affected file
3622 silcd/packet_send.c.
3624 * silc_idcache_del_by_context now deletes from all hash tables
3625 by context. Affected file lib/silccore/idcache.c.
3627 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3629 * Changed the client library to use the new ID Cache interface.
3630 Changes around the source tree.
3632 * Added silc_hash_table_rehash_ext to rehash with specific
3633 hash function. Affected file lib/silcutil/silchashtable.[ch].
3635 * Added silc_hash_string_compare to compare two strings in the
3636 hash table. Affected file lib/silcutil/silcutil.[ch].
3638 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3640 * Added new function silc_idcache_del_by_context into the
3641 lib/silccore/idcache.[ch].
3643 * Changed the server's ID list routines to use the new ID Cache
3644 interface. Changes around the source tree.
3646 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * Added silc_hash_table_del[_by_context]_ext functions in to the
3649 lib/silcutil/silchashtable.[ch].
3651 Removed silc_hash_table_find_all* routines and added new
3652 silc_hash_table_find_foreach to replace them.
3654 Added silc_hash_table_replace_ext function as extended
3655 replacing function. Separated the simple hash table interface
3656 from the extended hash table interface in the file
3657 lib/silcutil/silchashtable.h.
3659 * Fixed minor bugs and changed it to use some of the new
3660 hash table functions in lib/silccore/idcache.c
3662 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3664 * Added new function silc_hash_table_find_all to return all keys
3665 in the hash table by the specified key. As the hash table is
3666 collision resistant it also makes it possible to have several
3667 duplicate keys in the hash table. This function may be used to
3668 find all of the keys from the hash.
3670 Added user_context arguments to the SilcHashFunction,
3671 SilcHashCompare and SilcHashDestructor to deliver user specified
3674 Added new fuctions silc_hash_table_find[_all]_ext to do
3675 extended lookup with specified hash and compare functions and
3676 specified user contexts.
3678 Added new function silc_hash_table_add_ext to add the key
3679 with specified hash function and user context.
3681 Added new function silc_hash_table_foreach to traverse all
3682 entrys in the hash table. Added SilcHashForeach callback
3685 Added new function silc_hash_table_del_by_context to delete
3686 the entry only if the context associated with the key matches.
3688 Affected files are lib/silcutil/silchashtable.[ch].
3690 * Removed silc_hash_[server/client/channel]_id and added just
3691 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3692 silc_hash_id_compare to compare two ID's using as the hash table
3693 comparison function. Added also silc_hash_data to hash
3694 binary data and silc_hash_data_compare to compare it.
3696 * Removed silc_idlist_find_client_by_hash as it is not needed
3697 anymore. Affected file silcd/idlist.[ch].
3699 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3700 to use internally the SilcHashTable. The new ID Cache is a lot
3701 faster than the old one. Some of the ID Cache interface was also
3702 rewritten and obsolete and stupid functions were removed.
3704 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3706 * Added entry_count field to the SilcHashTable to keep the number
3707 of the entries in the table. Implemented the function
3708 silc_hash_table_rehash. Added new function
3709 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3711 Fixed a minor bug in silc_hash_table_free.
3713 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3714 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3715 into the lib/silcutil/silcutil.[ch].
3717 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3719 * Implemented a collision resistant hash table into the
3720 lib/silcutil/silchashtable[ch]. See the header and the source
3721 for the SilcHashTable API.
3723 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3725 * Merged dotconf version 1.0.2 into lib/dotconf.
3727 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3729 * Do not compile anything in lib/silcsim/* if the SIM support
3730 is not enabled. The tree should now compile without problems
3733 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3735 * Compiled the SILC under cygwin. Compiled and tested briefly
3736 without problems. More tests needed. The SIMs didn't compile
3739 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3741 * Fixed possible crash in silc_get_username in the
3742 lib/silcutil/silcutil.c.
3744 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3746 * Fixed a va_arg in silc/client_ops.c.
3748 * Oops, RC5 routines were named AES and caused some problems
3749 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3751 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Added new SilcIDIP structure into the lib/silccore/id.h and
3754 replaced the old `ip' fields from all SILC ID's to that type.
3755 This is a step towards IPv6 support.
3757 The silc_id_get_len takes now the ID as an extra argument.
3758 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3759 both IPv4 and IPv6 based ID's.
3761 The affected files are lib/silccore/id.[ch] and other files
3762 around the tree using these routines.
3764 * Removed the ID length arguments in server from various
3765 silc_server_send_notify_* routines -> they are not needed
3768 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3770 * Fixed memory leak in silc_encode_pem_file in the file
3771 lib/silcutil/silcutil.c.
3773 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Check minor version as well in the SKE. Affected files are
3776 silcd/protocol.c and lib/silcclient/protocol.c.
3778 * Added --identifier option to the server so that an identifier
3779 can be when creating the public key for the server. Affected
3780 file is silcd/silcd.c.
3782 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3783 lib/silccrypt/silcpkcs.c.
3785 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3787 * Register default ciphers and stuff when using -C option with
3788 the server. Affected file sildc/silcd.c.
3790 * Put back the servers public key filename format, it is better
3791 than the new one. For now, the client keys are saved with the
3792 new filename format. The affected file silc/client_ops.c.
3794 * Implemented the Cipher API for the rest of the ciphers that
3795 did not implement it or implemented it the wrong way.
3797 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3799 * Register default ciphers and stuff when using the -S option
3800 in the client. Affected file silc/silc.c. Same also when
3801 creating new key pair with -C option.
3803 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Fixed the silc_verify_public_key client operation function to
3806 save the public keys differently. The fingerprint is now
3807 used as filename and not the hostname. This way also the
3808 client keys are saved uniquely and not with hostnames. The
3809 affected file is silc/client_ops.c.
3811 * Trimmed the silc_hash_fingerprint function to remove extra
3812 whitespaces from the end of the fingerprint. The affected
3813 file is lib/silccrypt/silchash.c.
3817 * Added silc_cipher_register_default function to register all
3818 default ciphers. It can be used when configuration files
3819 does not exist and the application does not want any specific
3820 ciphers in any specific order.
3822 The SilcDList is now used as silc_cipher_list dynamically
3823 allocated cipher list. Removed the static list all together
3824 and now all ciphers must be allocated to the dynamic list.
3825 The silc_cipher_alloc routine was changed to check only the
3828 All silc_cipher_* routines that used to return int returns
3831 The affected files lib/silccrypt/silccrypt.[ch].
3833 * The same thing was done to silc_hash_* as for silc_cipher_*
3834 routines. Affected files lib/silccrypt/silchash.[ch].
3836 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3837 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3838 Added also silc_pkcs_[un]register[_default] functions.
3839 Removed the data_context from the PKCS API.
3841 * Added silc_hmac_register_default function to register default
3842 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3843 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3844 to unregister all hmacs at once.
3846 * Register the default ciphers, hash functions, PKCSs and HMACs
3847 if client's configuration file does not exist. The affected
3850 * The client did not load the hash functions from the SIM
3851 modules at all. Added support for this. Affected file is
3852 silc/clientconfig.c.
3854 * When decoding public key with silc_pkcs_public_key_decode, check
3855 the supported algorithm only if PKCS are registered. Affected
3856 file lib/silccrypt/silcpkcs.c. The same was done with the
3857 silc_pkcs_private_key_decode.
3859 * Fixed the SILC List routines to keep the list always in order.
3860 It used to change the list's order when traversing the list but
3861 not it preserves the order. Affected file lib/trq/silclist.h.
3863 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3865 * Added the client library to use the SilcSocketConnection's
3866 reference counter (by silc_socket_dup) to prevent the bug that
3867 the socket object may be freed underneath async operation.
3869 * The name resolv library checking fixes in the configure.in.pre.
3872 * Created new version of the protocol drafts for future
3873 development. The -03 drafts are the ones that will be changed
3874 in the trunk now and the -02 will remain as they are.
3876 * Send list of CUMODE notifys to the router when announcing
3877 the channel users to the router. Affected file silcd/server.c.
3878 If the router receiving channel founder CUMODE for a channel
3879 that already has channel founder it will send CUMODE notify
3880 to the sender to remove the channel founder rights from the
3881 announced client. Affected file silcd/packet_receive.c.
3883 * The CUMODE notify may now use Server ID as well as the entity
3884 who changes the mode. Updated protocool specs.
3886 * Updated INSTALL and README files.
3888 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3890 * New web pages in the http://silc.pspt.fi. The pages was
3895 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3897 * Implemented the [DenyConnectin] config section in the server.
3898 Added silc_server_config_denied_conn to check whether incoming
3899 connection is denied. Affected file silcd/serverconfig.[ch].
3901 * Do not check the ports when checking the incoming configuration
3902 data if the port is 0, meaning any. Affected file is
3903 silcd/serverconfig.c.
3905 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3907 * Fixed buffer overflow in silc_string_compare in the file
3908 lib/silcutil/silcutil.c.
3910 * Fixed double free in silc_server_command_leave in the file
3913 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3915 * Fixed the version checking in the server. Affected file is
3918 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3920 * Fixed the configuration data fetching when accepting new
3921 connections in the server. Affected file silcd/server.c.
3923 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3925 * Added `sender_entry' argument to the function
3926 silc_server_packet_relay_to_channel so that we can check
3927 whether some destination actually belongs to the same route
3928 the sender belongs (ie, we must not resend the packet to the
3929 sender). Affected file silcd/packet_send.[ch].
3931 * Added `servername' field to the SilcClientEntry in the server
3932 to hold the name of the server where client is from. Affected
3933 file is silcd/idlist.h.
3935 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3937 * Moved the channel message encrypting in the router betwen
3938 router connections from silc_server_channel_message to the
3939 silc_server_packet_relay_to_channel since we want to check
3940 whether we have anybody channel before encrypting anything.
3941 Affected files silcd/packet_[receive/send].c.
3943 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3945 * Fixed the [AdminConnection] server config section to support
3946 multiple entries. Affected file silcd/serverconfig.c.
3948 * Added support into the server to check the validity of the
3949 incoming connection before executing any KE or authentication
3952 * The connection configuration is now saved to the KE and
3953 connection auth protocol contexts and not fetched anymore in
3954 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3956 * The local hosts listenning address and port is also resolved
3957 now when starting the server. We want to have the socket object
3958 to include the real address and port for the listener. Added
3959 new function silc_net_check_local_by_sock into the files
3960 lib/silcutil/silcnet.[ch].
3962 * Fixed a broadcast bug in server -> do not broadcast if we
3965 * Fixed a routing bug. Do not route broadcast packets ever.
3966 Broadcast packets must be processed always and not routed since
3967 they may be destined to some other host than yourself and thus
3968 would get routed without no good reason. Affected file is
3971 * Added function silc_server_config_is_primary_route to check
3972 whether primary router connection has been configured (a router
3973 configuration that we are initiating). If there is not, we
3974 will assume that there is only two routers in the SILC network
3975 and we will use the incoming router connection as our primary
3976 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3978 * Changed the order of the broadcasting. Broadcast _after_ the
3979 packet has been processed not before. Affected file is
3982 * Fixed a [ClientConnection] parsing bug. The port was never
3983 parsed correctly thus resulting to port 0. Affected file
3984 silcd/serverconfig.c.
3986 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3987 argument and did not set the broadcast packet flag. Affected
3988 file silcd/packet_send.c. Fixed same bug in the function
3989 silc_server_send_notify as well.
3991 * If we receive NEW_ID packet for our own ID in the server, ignore
3994 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Removed the nickname from the Private Message Payload.
3999 Updated the code and the protocol specs.
4001 * Updated protocol specs for submitting to the IETF.
4003 * Tweaked the Random Number Generator a bit. Affected file
4004 lib/silccrypt/silcrng.c. Exported a new function
4005 silc_rng_[global]_add_noise which can be used to add more
4008 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4010 * Do not parse packets with different timeout when protocol
4011 is active -> may cause problem with rekey. Affected file
4014 * When server receives signoff notify it must not create
4015 new channel key if the client is on any channels since the
4016 sender of the signoff notify will create it.
4018 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4020 * Added printing of error messages during SKE protocol from the
4021 failure packet sent by server during SKE. Affected file
4024 * Removed the client's failure_callback handling with timeout
4025 and handle it immediately when received.
4027 * The SKE library returned wrong type in SUCCESS and FAILURE
4028 packets. They must be 32 bit MSB not 16 bit MSB.
4030 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4032 * Ok, rewrote the logic of the re-key and now it seems to work.
4033 I tested it on high traffic with frequent re-keys without
4034 problems. Added hmac_receive (and renamed hmac to hmac_send)
4035 in SilcClientConnection in lib/silcclient/client.h and
4036 in SilcIDListData in silcd/idlist.h. Also, removed the
4037 SilcPacketParserContext's cipher and hmac fields as they are
4038 not needed anymore and actually caused some problems when
4039 the ciphers and hmac's changed underneath the packet parser.
4041 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4043 * If re-key protocol is active then process the incoming packets
4044 synchronously since we must assure that icoming packets encrypted
4045 with the old key is processed before the new keys is set to
4046 use. This is true other packets than for REKEY packets.
4047 Affected file silcd/server.c. The same was done to client library
4048 as well, affected file lib/silcclient/client.c.
4050 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4052 * Fixed bug in client and server to accept the force send if
4053 the packet is send from silc_[server/client]_packet_process
4054 function. Otherwise the packets are never delivered, oops.
4056 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4058 * Disable force sending of packets when REKEY protocol is active.
4059 We must assure that no packet is sent directly when rekey is
4060 performed. All packets must be sent through packet queue.
4061 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4062 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4063 function is silc_[server/client]_packet_send_real to check
4066 * Replaced the SIM paths from example config files to
4067 /usr/local/modules. Also, make install creates now
4068 /usr/local/silc/logs directory to hold all the SILC server
4071 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4073 * Made the configure.in.pre work on Solaris. Patch by salo.
4075 * Made all ciphers compatible with non-x86 machines. Defined
4076 CBC mode macros into lib/silccrypt/ciphers_def.h.
4078 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4080 * Fixed the make install.
4082 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * When MAC computation fails the silc_packet_decrypt returned 0
4085 even though it was supposed to return -1. Fixed this. The
4086 affected file is lib/silccore/silcpacket.c.
4088 * Do not replace the config files in /etc/silc (in make install)
4089 if they already exist. Affected file ./Makefile.am.
4091 * Do not send re-key packets immediately but through packet queue.
4092 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4094 * Changed silc_net_check_host_by_sock to return FALSE if the
4095 IP/DNS could not be resolved. Though, it returns the IP address
4096 now even if it could not resolve it (but returns also FALSE).
4097 Affected file lib/silcutil/silcnet.[ch].
4099 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4101 * Added silc_pkcs_decode_identifier to decode the public key's
4102 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4103 Added also silc_pkcs_free_identifier. Added also new context
4104 SilcPublicKeyIdentifier.
4106 * Added -S option to the silc client. It is used to dump the
4107 contents of the specified public key file.
4109 * Changed the PKCS api to return the public key length when
4110 setting the public key.
4112 * Fixed a fatal bug in the public and private key file loading.
4113 Affected file lib/silccrypt/silcpkcs.c.
4115 * Execute the packet parsing for client with zero (0) timeout
4116 if the protocol is active. Affected file silcd/server.c.
4118 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4120 * Made the key generation options to the silcd program. Added
4121 -C option, equivalent to client's option.
4123 * Added new [ServerKeys] config section to the server. It
4124 configures the server's public and private key.
4126 * Defined generic Public Key Payload into the protocol
4127 specification to send specific type of public keys and
4130 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4131 public key or certificate.
4133 * Implemented the GETKEY command to the server and to the
4134 client library and on user interface.
4136 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Made preliminary `make install' work.

4167 SilcClientConnection structure; not needed. Affected file is
4168 lib/silcclient/client.h.
4172 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4174 * Do not ask whether user wants to use the negotiated private key
4175 for private messages, just use it. Affected file is
4176 silc/local_command.c.
4178 * Added `send_enc_key' and `enc_key_len' fields to the
4179 SilcIDListData structure since they are needed in the re-key
4180 phase. Affected file is silcd/idlist.[ch].
4182 * Implemented the simple re-key protocol into the server.

4194 the PFS is to be performed in the re-key. Affected file is
4197 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4200 int64 of at least the xintXX size. If void * is less that 4
4201 bytes uint32 * will be used. Defined bool as boolean.
4203 * Changed _ALL_ unsigned long and unsigned int to uint32,
4204 unsgined short to uint16 in the source tree.
4206 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4207 not handle clients that has entry->data.registered == FALSE.
4208 They are not in the network anymore. Affected file is
4211 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4213 * Implemented the sending of the SERVER_SIGNOFF notify in the
4214 server. Affected file is silcd/server.c.
4216 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4217 Added also silc_notify_payload_encode_args into the

4221 Affected file silcd/packet_receive.c.
4223 * Implemented the SERVER_SIGNOFF notify handling in the client
4224 library. Affected file lib/silcclient/client_notify.c. Also,
4225 implemnted the printing of the SERVER_SIGNOFF info to the
4226 application. Affected file silc/client_ops.c.
4228 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4229 if the deleting was successful. Affected file silcd/idlist.[ch].
4231 * Added support for public key authentication in the connection
4232 authentication protocol in the client library. Affected file
4233 lib/silcclient/protocol.c.
4235 * Changed the server's silc_idlist_get_clients_by_* interface
4236 to support already allocated array so that new entries may be
4237 added to pre-allocated array. Affected file silcd/idlist.[ch].
4238 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4239 and command replies.
4241 * All command reply functions in the server now calls the
4242 pending command callback even if error occured. This way the
4243 error will be delivered to the client as well. Affected files
4244 silcd/command.c and silcd/command_reply.c.
4246 * Fixed INFO command to return local server's info if no server
4247 was provided. Affected file lib/silcclient/command.c.
4249 * Removed RESTART command for good. Updated the code and the

4253 Removed unsued task priorities. The affected files are
4254 lib/silcutil/silctask.[ch].
4256 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4258 * Moved the USERS printing from the library to the application.
4259 Affected files lib/silcclient/command.c and silc/client_ops.c.
4261 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4265 * Added channel key re-key support. The re-key is perfomed
4266 only by the router and is done once in an hour. Added `rekey'
4267 field to the SilcChannelEntry in the server. Affected files
4268 silcd/server.c and silcd/idlist.h.
4270 * Added silc_task_unregister_by_context into the file
4271 lib/silcutil/silctask.[ch].
4273 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4275 * Added SILC_UMODE_GONE mode to indicate when the client is not
4276 present in the SILC network. Added also support to the local
4277 command AWAY that will set this mode. Added support of showing
4278 "xxx is gone" in WHOIS command. The USERS command shows the
4279 gone status as well.
4281 * Fixed setting server and router operator privileges in the
4282 server's UMODE command. Affected file silcd/command.c.
4284 * Merged the SKE KE1 and KE2 payloads into one payload. The
4285 new KE payload is equivalent to the old KE2 payload.
4287 Cleaned up the SKE Start Payload parsing. It now uses the
4288 simple buffer unformatting to do the parsing. A lot faster
4291 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4292 to the SKE that is used to indicate whether both of the SKE
4293 parties should perform authentication. By default only the
4294 responder performs authentication. By setting this flag also
4295 the initiator must do authentication. By default it is unset
4296 since in normal SKE case, client to server connection, only
4297 the responder should do authentication. When doing SKE between
4298 two clients both should perform authentication. Updated the
4299 code and the protocol specs.
4301 * A little fix to IDENTIFY command in the server. Search the
4302 client first by hash not nickname. Affected file is
4305 * Fixed the silc_client_close_connection to support closing
4306 the client to client connections wihtout deleting too much
4307 data. Affected file lib/silcclient/client.c.
4309 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4310 are received if protocol used to be active but is not anymore
4311 the application would crash due to NULL pointer dereference.
4312 Affected files silcd/server.c and lib/silcclient/client.c.
4314 * Added `hash' field to the SilcClientConnection to include
4315 the hash function negotiated in the SKE protocol.
4317 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4318 to set the channel founder authentication data. A client can
4319 claim the founder rights later by providing the authentication
4320 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4321 This way the channel founder can regain the channel founder
4322 privileges even it is left the channel. This works only on
4323 local server and the client must be connected to the same
4324 server to be able to regain the founder rights. Updated the
4325 protocol specs accordingly.
4327 Added support to the CMODE command in the client to set the
4328 founder auth data. Read the README to see how to set it.
4330 Added support to the CUMODE command to claim the founder
4331 rights. Read the README to see how to do it.
4333 Added support for the founder authentication to the Channel
4334 Entry in the server. Affected file silcd/idlist.h.
4336 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4337 server's CMODE command. Affected file silcd/command.c.
4339 * Added the following new functions into lib/silccore/silcauth.[ch]:
4340 silc_auth_get_method and silc_auth_get_data.
4342 * The server now saves the remote hosts public key to the
4343 SilcIDListData pointer. Affected file silcd/protocol.c.
4345 * The normal server now does not remove the channel entry from
4346 the cache if the founder authentication data is set. It used
4347 to remove it if the founder was the last one on the channel on
4348 the server and left the channel. The auth data is saved and
4349 if the channel is re-joined later the old entry is used with
4350 the old auth data. Affected files silcd/command_reply.c and
4353 * Removed the `pkcs' field from the SilcIDListData structure
4354 in the server; it is not used. Affected file silcd/idlist.h.
4356 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4358 * Fixed packet processing on slow links. Partial packets were
4359 never re-processed because the incoming data buffer was cleared
4360 by the application. Application must not directly clear the
4361 sock->inbuf, the packet processing routines handle it. Fixed
4362 this in client library and in server.
4364 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4366 * Fixed the WHOIS and IDENTIFY send reply function to really
4367 check whether to send list or just one entry. Affected file
4370 * Cleaned up the LEAVE command's channel key distribution. The
4371 affected file silcd/command.c.
4373 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4374 can enforce the channel mode as well. In that case the ID
4375 includes the ID of the server. The code now enforces the
4376 mode change if the router have different mode than the server.
4378 * The notify client operation with CMODE_CHANGE notify can now
4379 return NULL client_entry pointer if the CMODE was not changed
4380 by client. Application must check for this.
4382 * Added <Server ID> argument to INFO command to support server
4383 info fetching by Server ID.
4385 * Added silc_server_announce_get_channel_users to get assembled
4386 packets of channel users of the specified channel. Affected
4387 file silcd/server.[ch].
4389 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4390 was freed underneath the ID Cache.
4392 * Re-announce clients when the server received CHANNEL_CHANGE
4393 notify from the router. Affected file silcd/packet_send.c.
4395 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4397 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4398 crashed since it did not handle the fact that there is no cipher
4399 called "3" and didn't check the error condition. Now fixed.
4401 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4402 flag. It can be used to send message requests.
4404 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4406 * Implemented the RESTART command in the client.
4408 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4409 notice type messages. Added notice printing to the user
4412 * The channel keys are not re-generated if the channel's mode
4413 is PRIVKEY, ie private key on the channel exists. Affected
4414 files silcd/server.c and silcd/command.c.
4416 * Fixed a little bug in channel message delivery when channel
4417 private keys are set in the server. Affected file is
4418 silcd/packet_send.c.
4420 * Changed the setting on channel->on_channel = TRUE from the
4421 silc_client_save_channel_key to the JOIN command reply. The
4422 key payload is not received if the private channel key is set.
4423 Affected file lib/silcclient/command_reply.c and the
4424 lib/silcclient/client_channel.c.
4426 * When the CMODE_CHANGE notify is sent and the channel private
4427 key mode is removed the channel key must be re-generated in
4428 other cells as well. Added this support for the router in the
4429 silcd/packet_receive.c.
4431 * Added new local command NOTICE to send notice message on
4432 channel. Affected file silc/local_command.[ch].
4434 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4436 * Added new local command ME to the client. It is used to send
4437 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4438 some action. Affected file silc/local_command.[ch].
4440 * Changed channel_message and private_message client operations
4441 to deliver the message flags to the application. Added also
4442 the `flags' arguments to the silc_client_send_channel_message
4443 and silc_client_send_private_message functions. Affected file
4446 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4448 * Redefined the Private Message Payload to support private message
4449 keys and to support the new private message flags. Updated
4450 the protocol specs. Flags makes it possible to have for example
4451 CTCP style messages.
4453 * Added new type SilcPrivateMessagePayload and defined an API
4454 for it in the lib/silcclient/silcprivate.[ch].
4456 * Tested private message private keys successfully. Tested the
4457 private message key set, unset and list commands with the new
4460 * Redefined the Channel Message Payload to include the channel
4461 message flags (equal with private message flags) to support
4462 for example CTCP style messages.
4464 * Defined some of the message (for channel and private message)
4465 flags. Updated the protocol specs and added the flags to the
4466 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4468 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4470 * Added SilcKeyAgreementStatus type to the key agreement routines
4471 to indicate the current status and error if one occured.
4472 The status types are defined in the lib/silcclient/silcapi.h.
4474 * Added new local command KEY that is used to set and unset private
4475 keys for channels, set and unset private keys for private messages
4476 with remote clients and to send key agreement requests and
4477 negotiate the key agreement protocol with remote client. The
4478 key agreement is supported only to negotiate private message keys,
4479 it currently cannot be used to negotiate private keys for channels,
4480 as it is not convenient for that purpose.
4482 * Fixed a minor pending callback setting bug in the function
4483 silc_client_get_client_by_id_resolve, now the function works.
4484 Affected file lib/silcclient/idlist.c.
4486 * Added function silc_net_get_local_port to get local bound
4487 port by socket. Added to lib/silcutil/silcnet.[ch].
4489 * Added `sockets' and `sockets_count' fields to the SilcClient
4490 object. They hold the sockets of the listenning sockets in
4491 the client. Listenning sockets may be for example the key
4492 agreement server. Affected file lib/silcclient/client.[ch].
4493 Added functions the silc_client_add_socket and the
4494 silc_client_del_socket. They are exported to the application
4497 * Added ~./silc/clientkeys to support other client's public keys.
4499 * Renamed verify_server_key client operation to verify_public_key
4500 and added one argument to indicate the type of the connection
4501 (server, client etc.).
4503 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4505 * Added silc_server_connection_auth_request to handle the
4506 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4507 silcd/packet_receive.[ch].
4509 * Added silc_server_send_connection_auth_request into the
4510 silcd/packet_send.c to send the connection auth request packet.
4512 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4515 * Fixed the public key authentication in responder side in the
4516 server. The `auth_data' pointer includes the SilcPublicKey
4517 not the path to the public key. Affected file silcd/protocol.c.
4519 * Implemented the public key authentication in the initiator side
4520 in the server. Affected file silcd/protocol.c.
4522 * Removed the [RedirectClient] config section from the server
4523 configuration. Is not needed and I don't want to implement it.
4525 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4527 * Cleaned up the CMODE command in the server. It now works
4528 correctly and supports all the modes defined in the protocol.
4529 Affected file is silcd/command.c.
4531 * Added `hmac_name' field to the SilcChannelEntry in the server
4532 to hold the default HMAC of the channel. It can be set when
4533 creating the channel (with JOIN command). Affected files
4536 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4537 type to indicate the change of the current cipher and hmac
4538 on the channel. Client can safely ignore the <cipher> argument
4539 (if it chooses to do so) since the CHANNEL_KEY packet will
4540 force the channel key change anyway. The <hmac> argument is
4541 important since the client is responsible of setting the new
4542 HMAC and the hmac key into use.
4544 * Fixed the CMODE command in the client library as well.
4546 * Tested CMODE command in router environment successfully.
4548 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4550 * Show the version of the remote client (or server) when connecting
4551 to the server. It is logged to the log file. Affected file
4552 is silcd/protocol.c.
4554 * Fixed the KILLED notify handling in the client library. The
4555 client must be removed from all channels when receiving the
4558 Also, do not remove the client entry when giving the KILL
4559 command but when the KILLED notify is received.
4561 * Removed silc_idlist_find_client_by_nickname from the server.
4562 Not needed anymore. Affected files silcd/idlist.[ch].
4564 * Implemented the CHANNEL_CHANGE notify type handling to the
4565 server. Affected file silcd/server.c.
4569 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4571 * Added silc_server_send_notify_invite to send the INVITE
4572 notify between routers.
4574 * Implemented the INVITE command correctly to the server.

4583 * Added function silc_server_get_client_resolve to find the
4584 client entry by ID from all ID lists and then resolve it
4585 (using WHOIS) if it cannot be found. Affected file is
4588 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Implemented the BAN command to the client library.
4592 * The JOIN command in the server now checks the invite list
4595 * Changed the silc_command_reply_payload_encode_va and the
4596 silc_command_payload_encode_va to support that if argument is
4597 NULL it ignores and checks the next argument. Affected file
4598 lib/silccore/silccommand.c.
4600 * Added silc_server_send_notify_ban to send the BAN notify
4601 type between routers.
4603 * Chaned the silc_notify_payload_encode to support that if
4604 argument is NULL it ignores and checks the next argument.
4605 Affected file lib/silccore/silcnotify.c.
4607 * Tested ban lists in router environment successfully.
4609 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4611 * Implemented BAN command to the server, in silcd/command.[ch].
4613 * Removed the BAN and INVITE_LIST modes from the CMODE command
4616 * Added function silc_string_match to regex match two strings.
4617 Affected files lib/silcutil/silcutil.[ch].
4619 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4621 * Redefined parts of the SilcChannelEntry in the server to support
4622 the new ban and invite lists.
4624 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4626 * Redefined the INVITE command. The same command can be used to
4627 invite individuals to the channel but also to manage the invite
4628 list of the channel (to add to and remove from the invite list).
4629 Updated the protocol specs.
4631 * Added new command SILC_COMMAND_BAN that can be used to manage
4632 the ban list of the channel. Updated the protocol specs.
4634 * Removed the channel modes: the SILC_CMODE_BAN and the
4635 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4636 in the CMODE command. The equivalent features are now available
4637 using INVITE and BAN commands. Updated the protocol specs.
4639 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4640 in the network about change in the current ban list. The notify
4641 type is not used by the client.
4643 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4644 support the invite lists.
4646 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4648 * Added new function silc_string_regexify that converts string
4649 including wildcard characters into regex string that can
4650 be used by the GNU regex library. Added into the file
4651 lib/silcutil/silcutil.[ch].
4653 Added silc_string_regex_combine to combine to regex strings
4654 into one so that they can be used as one regex string by
4655 the GNU regex library. Added into the file
4656 lib/silcutil/silcutil.[ch].
4658 Added silc_string_regex_match to match two strings. It returns
4659 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4661 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4663 * Imported GNU regex to the soruce tree into lib/contrib.
4664 Fixed some compiler warning from the regex.c.
4666 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

4674 in the server, as the `nickname' argument may be binary data
4677 * Added silc_idlist_get_channels to return all channels from
4680 * Implemented LIST command to the server. Affected file is
4683 * Implemented the LIST command to the client library and on the
4686 * Added [<user count>] argument to the LIST command reply.
4687 With private channels the user count is not shown.
4689 * Updated TODO and README.
4691 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * The client entry's data.registered must be TRUE even with
4694 global client entry on global client list. The data.registered
4695 is used to check whether the client is anymore in the network,
4696 for example with WHOWAS command so it must be valid.
4698 * Fixed the WHOWAS command in the server. It now actually works
4699 in router environment. Added function into silcd/command_reply.c
4700 silc_server_command_reply_whowas_save.
4702 * Added silc_idlist_purge function to the silcd/idlist.c
4703 to periodically purge the ID Cache.

4713 they were buggy because of the WHOWAS information.
4715 * Fixed local command MSG to handle the async resolving of
4716 the remote client properly. It used to fail the first MSG.
4717 Affected file silc/local_command.c.
4719 * Added `data_len' field to SilcIDCache context.
4721 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4723 * Update TODO. Todo in commands in the server.
4725 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

4728 used by routers as broadcast packet to inform other routers
4729 about the changed user mode.
4731 Implemented the notify handling in the server. Affected file is
4732 silcd/packet_receive.c. Added the function
4733 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4735 * Added new generic Channel Payload and deprecated the New Channel
4736 Payload. The New Channel Payload is now the generic Channel
4739 * Added new argument `mode' to the silc_server_send_new_channel
4740 as it is required in the Channel Payload now.
4742 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4743 and created a new and real SilChannelPayload to represent the
4744 new generic Channel Payload. Implemented the encode/decode
4745 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4747 * Added silc_server_get_client_channel_list to return the list
4748 of channels the client has joined for WHOIS command reply.
4749 Affected file silcd/server.[ch].
4751 * Implemented the channel list sending in the WHOIS command reply
4752 in server and in the client.
4754 Implemented the channel list displaying on the user interface
4755 as well. Affected file silc/client_ops.c.
4757 * Added silc_channel_payload_parse_list to parse list of Channel
4758 Payloads. It returns SilcDList list of SilcChannelPayloads.
4759 Client for example can use this function to parse the list of
4760 channels it receives in the WHOIS command reply. The caller
4761 must free the list by calling silc_channel_payload_list_free.
4762 Affected files lib/silccore/silcchannel.[ch].
4764 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4766 * Added one new argument <user mode> to the WHOIS command reply

4783 unknown command. Affected file silcd/command.c.
4785 * All server commands now handle the command identifier the right
4786 way when sending the command reply to the client. The client can
4787 use to identify the command replies with the identifier.
4789 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4791 * Added silc_server_get_client_route to resolve the route to
4792 the client indicated by the client ID. Affected file is
4795 * Added silc_server_relay_packet as general function to relay
4796 packet to arbitrary destination. This deprecates functions
4797 like _send_private_message_key, _relay_notify etc. Affected
4798 file is silcd/packet_send.[ch].
4800 Removed silc_server_send_key_agreement,
4801 silc_server_send_private_message_key and
4802 silc_server_packet_relay_notify functions from the file
4803 silcd/packet_send.[ch].
4807 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4808 server. Affected file silcd/packet_receive.[ch].
4810 * Implemented the KILL command to the client. Implemented the
4811 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4812 Affected files lib/silcclient/command[_reply].c and
4813 lib/silcclient/client_notify.c. Implemented the KILL notify
4814 printing in the user inteface.
4816 * Fixed a lot silc_parse_nick memory leaks from the client
4817 library in the file lib/silcclient/command.c.
4819 * Changed the silc_server_send_notify_on_channels's `sender'
4820 argument from SilcSocketConnection to SilcClientEntry to
4821 check the sender as entry and not as connection object and not
4822 to send to the client provided as argument. The affected file
4823 is silcd/packet_send.[ch].
4825 * The notify packets that are destined directly to the client used
4826 to not to be processed by the server. Now changed that and the
4827 server processes all notify packets. After relaying the packet
4828 to the client the notify packet is processed in the server.
4830 * The silc_server_free_client_data now checks whether there is
4831 pending outgoing traffic for the client and purges the data to
4832 the network before removing the client entry.
4834 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4837 an client is killed from the SILC Network. Updated the protocol
4840 Added new function silc_server_send_notify_killed to the
4841 silcd/packet_send.[ch].
4843 * Added function silc_server_packet_relay_notify to relay notify
4844 packets that are destined directly to a client. In this case
4845 the server does not process the notify packets but merely relays
4846 it to the client. Affected file silcd/packet_send.[ch].
4848 Added also silc_server_packet_process_relay_notify to check
4849 whereto relay the notify. Affected file is
4850 silcd/packet_receive.[ch].
4852 * Implemented the KILL command to the server.
4856 * Added the backup schema desgined last fall to the protocol
4857 specs for everyone to see. The specification is in the
4858 *-spec-xx.txt draft and the packet type definitions for the
4859 backup routers is in *-pp-xx.txt draft. Thusly, added also
4860 new packet type SILC_PACKET_CELL_ROUTERS.
4862 * A big security problem in the implementation discovered. The
4863 signoff of an client did not cause new channel key generation
4864 which it of course should've done. The channel keys must be
4865 always re-generated when client leaves (or signoffs) the channel.
4866 The silc_server_remove_from_channels funtion now handles
4867 the channel key re-generation.
4869 * Added `sender' argument to the silc_server_send_notify_on_channels
4870 to not to send the client provided as argument. Affected file
4871 silcd/packet_send.[ch].
4873 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4875 * Implemented OPER and SILCOPER commands into the server and
4878 * Added silc_auth_verify and silc_auth_verify_data to verify
4879 the authentication directly from the authentication payload.
4880 It supports verifying both passphrase and public key based
4881 authentication. Affected file lib/silccore/silcauth.[ch].
4883 * Added `hash' field to the SilcIDListData structure. It is the
4884 hash negotiated in the SKE protocol. Affected file is
4887 * Slight redesigning of the SilcAuthPayload handling routines.
4888 Do not send SilcPKCS but SilcPublicKey as argument.
4890 * Implemented the public key authentication support to the
4891 serverconfig. The public key is loaded from the provided path
4892 and saved as authentication data to void * pointer. Thus,
4893 changed the unsigned char *auth_data to void *auth_data;
4895 * Fixed SHUTDOWN command to send the reply before the server
4896 is shutdown. :) Affected file silcd/command.c.
4898 * Fixed fatal bug in CONNECT command. The hostname was invalid
4899 memory and server crashed. Affected file silcd/command.c.
4901 * Fixed fatal bug in CLOSE command. The server_entry became
4902 invalid but was referenced later in the command. Affected file
4905 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * Fixed fatal bug in failure packet handling. Server ignored
4908 the failure and thus crashed when it came.
4912 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4914 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4915 that the command may be executed only once in (about) 2 seconds.
4916 The old SILC_CF_LAG flag is same but allows command bursts up
4917 to five before limiting.
4919 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4920 server code. Various commands now includes the CF_LAG_STRICT
4921 flag to disallow any kind of miss-use of the command.
4923 * Fixed the silc_buffer_unformat to not to allocate any data
4924 if the length of the data is zero. It used to allocate the
4925 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4927 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4929 * Changed the format of AdminConnection configuration section
4930 in the server. Added username of the admin to the format.
4931 Affected files silcd/serverconfig.[ch].
4933 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4934 to return admin configuration data by host, username and/or
4937 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4939 * Implemented WHOWAS command to the server. Added the functions:
4941 silc_server_command_whowas_parse,
4942 silc_server_command_whowas_send_reply,
4943 silc_server_command_whowas_from_client and
4944 silc_server_command_whowas_from_server
4946 * Added <Client ID> argument to the WHOWAS command reply. Updated
4947 the protocol specs accordingly.
4949 * Implemented WHOWAS command and command_reply to the client
4952 Implemented the WHOWAS printing on the user interface.
4954 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4956 * Added new argument to the WHOWAS command reply, the real name.
4957 It is an optional argument. Updated the protocol specs.
4959 * Added SilcIDCacheDestructor callback that is registered when
4960 the SilcIDCache is allocated. The callback is called when
4961 an cache entry in the ID Cache expires, or is purged from the
4962 cache. Added into lib/silccore/idcache.[ch].
4964 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4965 to destruct the client entries when the cache entry expires.
4966 Other ID Cache's in server and in the client library ignores
4969 * If the ID Cache entry's `expire' field is zero then the entry
4970 never expires. Added boolean `expire' argument to the
4971 silc_idcache_add function in the lib/silccore/idcache.[ch].
4972 If it is TRUE the default expiry value is used.
4974 * Added silc_server_free_client_data_timeout that is registered
4975 when client disconnects. By default for 5 minutes we preserve
4976 the client entry for history - for WHOWAS command.
4978 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4980 * Added support to the server to enforce that commands are not
4981 executed more than once in 2 seconds. If server receives
4982 commands from client more frequently, timeout is registered
4983 to process the commands. Affected file silcd/command.c.
4984 Added new function silc_server_command_process_timeout.
4986 * Changed NICK_NOTIFY handling in client library to check that
4987 if the client's nickname was changed, so there is no need to
4988 resolve anything from the server.
4990 * Removed error printing from the WHOIS and IDENTIFY commands.
4991 If error occurs then it is ignored silently in the client library.
4992 The application, however, may map the received error to
4993 human readable error string. The application currently maps
4994 the NO_SUCH_NICKNAME error to string.
4996 * Made the command status message public to the application. Moved
4997 them from lib/silcclient/command_reply.c to
4998 lib/silcclient/command_reply.h. The application can map the
4999 received command status to the string with the
5000 silc_client_command_status_message function.
5002 * Added check to the server to check that client's ID is same
5003 as the Source ID in the packet the client sent. They must
5006 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5008 * Added dist-bzip hook to the Makefile.am to make bzip2
5009 compressed distributions.
5011 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5013 * Server now enforces the maximum length for the nickname and
5014 the channel as protocol specification dictates. 128 bytes for
5015 nickname and 256 bytes for channel name.
5017 * Moved the WHOIS printing to the application. The client libary
5018 does not print out the WHOIS information anymore, the application
5019 must do it. Renamed silc_client_command_reply_whois_print to
5020 the silc_client_command_reply_whois_save.
5022 The client's idle time is also sent to the application now, and
5023 the idle is shown on screen.
5025 * Added silc_client_command_reply_identify_save to save the
5026 received IDENTIFY entries.
5028 * Do not check for channel private keys in message sending and
5029 reception if the channel does not have the PRIVKEY mode set.
5030 Affected file lib/silclient/client_channel.c.
5032 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5034 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5035 just surfaced after chaning the JOIN procedure.
5037 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5039 * Added silc_client_get_clients_by_list to get client entries
5040 from Client ID list, that is returned for example by JOIN
5041 and USERS command replies. The application should use this
5042 function for example when JOIN command reply is received to
5043 resolve the clients already on the channel (library does not
5044 do that anymore as USERS command reply is not used in the JOIN
5045 procedure anymore). Affected files lib/silcclient/silcapi.h and
5046 lib/silcclient/idlist.c.
5048 * JOIN command reply and USERS command reply returns now SilcBuffer
5049 pointers instead of unsigned char pointers when returning
5050 the client list and mode list.
5052 * Added <Client ID> argument to the JOIN command reply, mainly
5053 for the server to identify for which client the command was
5054 originally sent. Updated protocol specs accordingly.
5056 * Added SilcDlist private_key pointer to the SilcChannelEntry
5057 in the client to support the channel private keys. Affected
5058 file is lib/silcclient/idlist.h.
5060 * Added SilcChannelPrivateKey argument to the function
5061 silc_client_send_channel_message so that application can choose
5062 to use specific private ke if it wants to. If it is not provided,
5063 the normal channel key is used, unless private keys are set.
5064 In this case the first (key that was added first) is used
5065 as the encryption key.
5067 * Implemented the support for channel private key handling.
5068 Implemented the following functions:
5070 silc_client_add_channel_private_key,
5071 silc_client_del_channel_private_keys,
5072 silc_client_del_channel_private_key,
5073 silc_client_list_channel_private_keys and
5074 silc_client_free_channel_private_keys
5076 Affected file lib/silcclient/client_channel.c.
5078 * Added the support for the private keys in the channel message
5079 sending and encryption and in the message reception and
5080 decryption. Affected funtions are
5081 silc_client_send_channel_message and silc_client_channel_message.
5083 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5085 * Added SKE's key verify callback to the client library's
5086 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5088 * Removed the statement that server (or router) must send USERS
5089 command reply when joining to the channel so that the client
5090 knows who are on the channel. Instead, the client list and
5091 client's mode list is now sent in the JOIN command reply to the
5092 client who joined channel. This is better solution.
5094 * Added function silc_server_get_users_on_channel and function
5095 silc_server_save_users_on_channel to the silcd/server.[ch].
5097 * Removed function silc_server_command_send_users from the
5100 * Do not show topic on the client library anymore. The topic is
5101 sent in the command reply notify to the application and the
5102 application must show the topic now.
5104 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5106 * Added client searching by nickname hash into the IDENTIFY and
5107 WHOIS commands in the server as they were clearly missing from
5108 them. Affected file is silcd/command.c.
5110 * Fixed a bug in private message receiving in the client library.
5111 The remote ID was freed and it wasn't supposed, now it is
5114 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5116 * Minor fix to the channel payload; allocate the data area, as it
5117 needs to be of specific length.
5119 * If the key agreement port is zero then the operating
5120 system will define the bound port. Affected files are
5121 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5123 * Added new function silc_channel_payload_decrypt into the file
5124 lib/silccore/silcchannel.[ch].
5126 * Moved the channel message etc, check from silc_packet_decrypt
5127 to applications. The library calls now a generic
5128 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5129 when the packet is either normal or special. This was done to
5130 allow more wide range of checking that was not allowed when
5131 the code was in library. Now applications can do virtually any
5132 checks to the packet and return to the library the decision how
5133 the packet should be processed. Affected files are
5134 lib/silccore/silcpacket.[ch].
5136 Added silc_server_packet_decrypt_check to the server and
5137 silc_client_packet_decrypt_check to the client library.
5139 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5140 to send with specified source and destination information.
5142 * Channel message delivery between routers was broken after the
5143 channel key distribution was fixed earlier. The channel key
5144 was used be to distributed to other routers as well which is not
5145 allowed by the protocol. Now this is fixed and channel keys
5146 really are cell specific and the channel message delivery between
5147 routers comply with the protocol specification.
5149 * Fixed various commands in server to check also the global list
5150 for the channel entry and not just the local list. The affected
5151 file silcd/command.c.
5153 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5155 * Added assert()s to buffer formatting and unformatting routines
5156 to assert (if --enable-debug) when error occurs. Affected
5157 file: lib/silcutil/silcbuffmt.c.
5159 * Changed to auto-reconnect to check whether the remote host is
5160 router and register the re-connect timeout if it is. It used
5161 to check that whether we are normal server, but router must do
5162 auto-reconnect with another router as well. Affected file
5165 * Removed the [<key len>] option from CMODE command as the cipher
5166 name decides the key length, nowadays. See the defined ciphers
5167 from the protocol specification.
5169 * Added [<hmac>] option to the CMODE command to define the HMAC
5170 for the channel. Added SILC_CMODE_HMAC channel mode.
5172 * Added [<hmac>] option for the JOIN command so that user can
5173 select which HMAC is used to compute the MACs of the channel
5176 * Added Hmac field to the Channel Message Payload. The integrity
5177 of plaintext channel messages are now protected by computing
5178 MAC of the message and attaching the MAC to the payload. The
5179 MAC is encrypted. Now, it is clear that this causes some
5180 overhead to the size of the packet but rationale for this is that
5181 now the receiver can verify whether the channel message decrypted
5182 correctly and also when private keys are set for the channel the
5183 receiver can decrypt the packet with several keys and check from
5184 the MAC which key decrypted the message correctly.
5186 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5187 lib/silccrypt/silccipher.[ch].
5189 * Added silc_hash_len to return the digest length into the
5190 lib/silcrypt/silchash.[ch].
5192 * Rewrote parts of Silc Channel Payload interface in the
5193 lib/silccore/silcchannel.[ch]. The encode function now also
5194 encrypts the packet and parse function decrypts it.
5196 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5198 * Fixed a minor formatting bug in the SKE's key material processing.
5199 It actually might have processed the keys wrong way resulting
5202 * Redefined the mandatory HMAC algorithms and added new algorithms.
5203 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5204 and hmac-md5 truncated to 96 bits. The mandatory is now
5205 hmac-sha1-96. Rest are optional (including the one that used
5206 to be mandatory). Rationale for this is that the truncated HMAC
5207 length is sufficient from security point of view and can actually
5208 make the attack against the HMAC harder. Also, the truncated
5209 HMAC causes less overhead to the packets. See the RFC2104 for
5212 * Added new [hmac] configuration section. The SKE used to use
5213 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5214 is of course wrong. The official names that must be proposed in
5215 the SKE are the ones defined in the protocol specification
5216 (hmac-sha1-96 for example). The user can configure any hmac
5217 using any hash function configured in the [hash] section. At
5218 least, the mandatory must be configured.
5220 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5222 * Added HMAC list to the SKE proposal list. It has now both
5223 hash algorithm list and HMAC list. This makes the protocol
5224 incompatible with previous versions. The SKE now seems to work
5225 the way it is supposed to work, for the first time actually.
5227 * Defined plain Hash algorithms to the protocol specification.
5230 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5232 * Implemented support for key agreement packets into the server.
5233 Added functions silc_server_key_agreement and
5234 silc_server_send_key_agreement. Other than these functions,
5235 server has nothing to do with this packet.
5237 * Added support for private message key packets into the server.
5238 Added functions silc_server_private_message_key and
5239 silc_server_send_private_message_key.
5243 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5244 called in the protocol's final callback instead in the END
5245 protocol state. This makes a little more sense and in the same
5246 time in client we can use the same protocol routines for normal
5247 key exchange and to key agreement packet handling as well.
5249 * Added to both client's and server's KE protocol context the
5250 SilcSKEKeyMaterial pointer to save the key material. We will
5251 bring the key material to the protocol's final callback by doing
5252 this. The final callback must free the key material.
5254 * Added SKE's packet_send callback into client's KE protocol
5255 context so that the caller can choose what packet sending function
5256 is used. This way we can use different packet sending when
5257 doing normal SKE when doing key agreement packet handling (in
5258 the key agreement packet handling we do not want to encrypt
5261 * Implemented the responder side of the key agreement routines
5262 in the client. The client can now bind to specified port and
5263 accept incoming key negotiation. The key material is passed
5264 to the application after the protocol is over.
5266 * Implemented the processing of incoming Key Agreement packet
5267 in the client. Added function silc_client_key_agreement to
5270 * Implemented the intiator side of the key agreement routines
5271 in the client. The client can now initiate key agreement with
5272 another remote client. The key material is passed to the
5273 application after the protocol is over.
5275 * Created client_keyagr.c to include all the key agreement
5278 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5279 SILC_TASK_CALLBACK except that it is not static.
5281 * Created client_notify.c and moved the Notify packet handling
5282 from the client.[ch] into that file.
5284 * Created client_prvmsg.c and moved all private message and
5285 private message key routines from the client.[ch] into that file.
5287 * Create client_channel.c and moved all channel message and
5288 channel private key routines from the client.[ch] into that file.
5290 * Changed silc_client_get_client_by_id_resolve to resolve with
5291 WHOIS command instead of IDENTIFY command, in the file
5292 lib/silclient/idlist.c.
5294 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5296 * Implemented the SKE's responder side to the Client library.
5298 * When FAILURE is received to the protocol do not trust it
5299 blindly. Register a timeout to wait whether the remote closes
5300 the connection as it should do it, only after that process the
5301 actual failure. This was changed to both client and server.
5303 * Added client_internal.h to include some of the structures
5304 there instead of client.h in lib/silcclient/.
5306 * Added function silc_task_unregister_by_callback to unregister
5307 timeouts by the callback function.
5309 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5311 * Some "Incomplete WHOIS info" errors has been appearing on the
5312 log files. Took away the entry->userinfo check from WHOIS
5313 reply sending. The entry->userinfo is now " " if client did not
5314 provide one. I thought this was fixed earlier but something
5315 is wrong still. Let's see if the error still appears.
5317 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * Fixed a minor bug in the login when the channel key is
5320 re-generated in the server. It used to generate the key in
5321 wrong order and thus caused problems in the channel traffic.
5323 * Fixed a minor bug in channel key distsribution after
5324 KICK command. The key was not sent to the router even though
5327 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5329 * Added silc_ske_process_key_material_data as generic routine
5330 to process any key material as the SILC protocol dictates. The
5331 function is used by the actual SKE library but can be used by
5332 applications as well. This relates to the private message keys
5333 and the channel private keys since they must be processed the
5334 same way the normal SILC session keys. The protocol dictates
5335 this. Affected files: lib/silcske/silcske.[ch].
5337 Added also silc_ske_free_key_material to free the
5338 SilcSKEKeyMaterial structure.
5340 * Defined silc_cipher_set_key function to set the key for
5341 cipher without using the object's method function. The affected
5342 files: lib/silccrypt/silccipher.[ch].
5344 * Implemented silc silc_client_add_private_message_key,
5345 silc_client_add_private_message_key_ske,
5346 silc_client_del_private_message_key,
5347 silc_client_list_private_message_keys and
5348 silc_client_free_private_message_keys functions in the
5351 Added functions silc_client_send_private_message_key to send
5352 the Private Message Key payload and silc_client_private_message_key
5353 to handle incoming Private Message Key payload.
5355 * Added Cipher field to the Private Message Key payload to set
5356 the cipher to be used. If ignored, the default cipher defined
5357 in the SILC protocol (aes-256-cbc) is used.
5359 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5361 * Removed lib/silcclient/ops.h file.
5363 Redefined parts of the SILC Client Library API. Created new
5364 file silcapi.h that deprecates the ops.h file and defines the
5365 published Client Library API. Defined also private message key
5366 API and channel private key API into the file.
5368 This is the file that the application must include from the
5369 SILC Client Library. Other files need not be included by
5370 the application anymore.
5372 * Added new key_agreement client operation callback and also
5373 defined the Key Agreement library API for the application.
5375 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5377 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5378 is used by clients to request key negotiation between another
5379 client in the SILC network. If the negotiation is started it
5380 is performed using the SKE protocol. The result of the
5381 negotiation, the secret key material, can be used for example
5382 as private message key.
5384 Implemented the Key Agreement payload into the files
5385 lib/silccore/silauth.[ch].
5387 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5389 * Redefined ciphers for the SILC protocol. Added some new ciphers
5390 and defined the key lengths for the algorithms. Changed the
5391 code accordingly. The default key length is now 256 bits.
5393 * Fixed SKE key distribution function silc_ske_process_key_material
5394 when the key length is more than 128 bits. The default key
5395 length in SILC is now 256 bits.
5397 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5398 to indicate unsupported algorithm.
5400 * Renamed rijndael.c to aes.c and all functions as well.
5402 * Fixed a long standing channel key setting bug in client library.
5403 Weird that it has never surfaced before.
5405 * Fixed bug in channel deletion. If the entire channel is removed
5406 then it must also delete the references of the channel entry
5407 from the client's channel list as the client's channel entry and
5408 the channel's client entry share same memory.
5410 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Implemented CONNECT and SHUTDOWN commands in the client.
5414 * Implemented CLOSE command to the client.
5416 * Added the function silc_idlist_find_server_by_name into the
5417 files silcd/idlist.[ch].
5419 Added the function silc_idlist_find_server_by_conn into the
5420 files silcd/idlist.[ch].
5422 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * DIE command was renamed to SHUTDOWN. Updated the both code
5427 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5428 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5430 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5433 * Added function silc_server_create_connection function to create
5434 connection to remote router. My server implementation actually
5435 does not allow router to connect to normal server (it expects
5436 that normal server always initiates the connection to the router)
5437 so the CONNECT command is only good for connecting to another
5440 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5442 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5443 or some other client was kicked from the channel.
5445 Implemented the handling of the notify type to both client
5448 Implemented silc_server_send_notify_kicked to send the KICKED
5449 notify. It is used to send it to the server's primary router.
5451 * Implemented the KICK command into server and client.
5453 * Added `query' argument to the silc_idlist_get_client function
5454 to indicate whether to query the client from server or not if
5457 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5458 to indicate that the client is not channel founder.
5462 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5464 * Removed the rng context from SilcPacketContext structure and
5465 changed that the packet routine uses the Global RNG API.
5467 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5469 * Added support for quit message that client can "leave" on the
5470 channel when it quits the SILC. It is ditributed inside the
5471 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5473 Added silc_server_free_client_data that will take the
5474 signoff message as argument.
5476 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5478 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5480 * Updated parts of the protocol specification to keep it up
5483 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5485 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5486 payloads in one packet.
5488 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5489 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5490 use now the new List flag.
5492 * Also deprecated the following packet types: REPLACE_ID,
5493 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5495 * Added list support for Notify packet in server.
5497 * Added silc_server_send_notify_channel_change to send the
5498 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5499 the silc_server_send_replace_id.
5501 * Added silc_server_send_notify_nick_change to send the
5502 NICK_CHANGE notify type. Deprecates the function
5503 silc_server_send_replace_id.
5505 * Added silc_server_send_notify_join to send the JOIN notify type.
5506 Deprecates the function silc_server_send_new_channel_user.
5508 * Added silc_server_send_notify_leave to send LEAVE notify type.
5509 Deprecates the function silc_server_send_remove_channel_user.
5511 * Added silc_server_send_notify_cmode and
5512 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5513 types. Deprecates the silc_server_send_set_mode function.
5515 * Added SERVER_SIGNOFF notify type to indicate that server has
5516 quit. This means that all clients on the channel from that
5517 server will drop. This can be also used when netsplit happens.
5519 Deprecated REMOVE_ID packet type since it is not needed anymore
5522 Added silc_server_send_notify_server_signoff to send the
5523 SERVER_SIGNOFF notify type. Deprecates the function
5524 silc_server_send_remove_id.
5526 Added also silc_server_send_notify_signoff to send the
5527 SIGNOFF notify type.
5529 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5530 SILC protocol from this day on. Changed the protocol
5531 specification as well.
5533 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5534 notify type. It is used between routers to notify about
5535 topic changes on a channel.
5537 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5540 * Partly updated the protocol specification to comply with the
5541 changes now made. It is still though a bit outdated.
5543 * The JOIN notify type now takes one extra argument <Channel ID>.
5544 The packet used to be destined to the channel but now the
5545 JOIN type may be sent as list thus it is impossible to
5546 destine it to any specific channel. By adding this argument
5547 it is again possible.
5549 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5551 * Added CREDITS file. The CHANGES and CREDITS file will appear
5552 in the distribution as well.
5554 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5556 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5557 types in the server's silcd/packet_receive.c.
5559 * Implemented CMODE and CUMODE to work in router environment.
5561 * Fixed minor encoding and decoding buglet from the
5562 lib/silccore/silcmode.c.
5564 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5567 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5569 * Changed all SilcConfigServer* and silc_config_server* to
5570 SilcServerConfig* and silc_server_config*, respectively.
5573 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5575 * Associated the ID (client or server ID) to the Authentication
5576 Payload to avoid any possibility of forging. Updated the
5577 protocol specification and the code accordingly.
5579 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5581 * The RSA key length is now save to the RsaKey context in the
5582 key generation process in lib/silccrypt/rsa.c. The key length
5583 is now used to figure out the maximum size of the block allowed
5584 to be encrypted/signed.
5586 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5587 is equivalent to the silc_mp_mp2bin but does not allocate any
5590 * Changed silc_mp_mp2bin API to take length argument. If it is
5591 non-zero then the buffer is allocated that large. If zero, then
5592 the size is approximated using silc_mp_sizeinbase, which however
5595 * Created Global RNG API which is global RNG that application can
5596 initialize. After initializing, any routine anywhere in the
5597 code (including library) can use RNG without allocating a new
5598 RNG object. This was done to allow this sort of use of the
5599 RNG in code that has no chance to allocate RNG object. All
5600 applications currently allocate this and many routines in the
5601 library use this. Affected file lib/silccrypt/silcrng.[ch].
5603 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5604 it to use the Global RNG API.
5606 * Defined Authentication Payload into protocol specification that
5607 is used during SILC session to authenticate entities. It is
5608 used for example by client to authenticate itself to the server
5609 to obtain server operator privileges.
5611 Implemented this payload into the lib/silccore/silcauth.[ch].
5612 Implemented also routines for public key based authentication
5613 as the new protocol specification dictates.
5615 Moved definitions of different authentication methods from
5616 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5618 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5619 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5620 silc_pkcs_verify_with_hash functions into the file
5621 lib/silccrypt/silcpkcs.[ch].
5623 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5625 * The client entry's userinfo pointer must be always valid.
5626 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5627 will fail since it requires the userinfo. Now, the userinfo
5628 is allocated as "" if actual userinfo does not exist. Actually,
5629 it must exist and it is totally Ok to drop client connections
5630 that does not announce the userinfo. However, we will make
5631 this workaround for now.
5633 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5634 to return the remote port by socket.
5636 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5638 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5639 SILC_SERVER_PENDING_EXEC and added an new macro
5640 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5641 data or when error occurs while processing the pending command.
5643 Added new argument `destructor' into silc_server_command_pending
5644 and to the SilcServerCommandPending object. This destructor is
5645 now called after calling the pending callback or if error occurs
5646 immediately. If error occurs the actual pending callback won't
5647 be called at all - only the destructor. The destructor may be
5648 NULL if destructor is not needed.
5650 All this applies for client library code as well. Similar
5651 changes were made there as well for the pending commands.
5653 In the client, the application must now allocate the
5654 SilcClientCommandContext with the silc_client_command_alloc
5657 * Added reference counter to the SilcServerCommandContext. Added
5658 function silc_server_command_alloc and silc_server_command_dup
5661 Same type of functions added to the client library for the same
5664 * Removed the cmd_ident from IDListData away since it is now
5665 global for all connections. It is the command identifier used
5666 in command sending and with pending commands. The affected file
5669 * Added reference counter to the SilcSocketConnection objecet to
5670 indicate the usage count of the object. The object won't be
5671 freed untill the reference counter hits zero. Currently only
5672 server uses this, and client ignores it. The client must be
5673 set to use this too later. The affected files are
5674 lib/silccore/silcsockconn.[ch]. Added also the function
5675 silc_socket_dup to increase the reference counter.
5677 This was mainly added because it is possible that the socket
5678 is removed underneath of pending command or other async
5679 operation. Now it won't be free'd and proper DISCONNECTING
5680 flags, etc. can be set to avoid sending data to connection that
5681 is not valid anymore.
5683 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5684 the connection. After that it sets SILC_SET_DISCONNECTED.
5685 It is, however, possible that the socket data is not still freed.
5686 The silc_server_packet_process now checks that data is not
5687 read or written to connection that is DISCONNECTED. The socket
5688 get's freed when the reference counter hits zero.
5690 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5692 * Changed the client operation API: channel_message operation's
5693 `sender' is now the client entry of the sender, not the nickname
5694 and the `channel' is the channel entry, not the channel name.
5696 In the private_message operation the `sender' is now also the
5697 client entry of the sender not the nickname.
5699 Affected file is lib/silcclient/ops.h and all applications
5700 using the client operations.
5702 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5704 * Moved the calling of ops->connect() from connect_to_server_final
5705 into receive_new_id functin since that is the point when the
5706 client is actually allowed to send traffic to network. The
5707 affected file is lib/silcclient/client.c.
5709 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5711 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5712 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5713 (if needs broadcasting) instead of broadcasting the packets one
5714 by one which would make a burst in the network traffic.
5716 * Added `broadcast' argument to the functions in silcd/server.[ch]
5717 silc_server_create_new_channel[_with_id] to indicate whether
5718 to send New Channel packet to primary router.
5720 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5722 * Added new function into the silcd/server.[ch] files:
5723 silc_server_create_new_channel_with_id to create new channel with
5724 already existing Channel ID.
5726 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5727 lib/silccore/silcpacket.h. This packet is used t send list of
5728 Set Mode payloads inside one packet. Server uses this to set
5729 the modes for the channels and clients on those channels, that it
5730 announced to the router when it connected to it. The protocol
5731 specification has been updated accordingly.
5733 * The silc_server_new_channel did not handle the packet coming
5734 from normal server as it normally does not send that. However,
5735 when it announces its channels it does send it. Implemented
5736 the support for that.
5738 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5739 into the file lib/silccore/id.h.
5741 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5743 * Fixed memory leaks in the functions silc_idlist_del_client,
5744 silc_idlist_del_channel and silc_idlist_del_server in the file
5745 silcd/idlist.c. All of those leaked like a sieve.
5747 * Fixed some small memory leaks in the client's function
5748 silc_client_notify_by_server.
5750 * Added functions into silcd/server.c: silc_server_announce_clients,
5751 silc_server_announce_channels and silc_server_announce_server.
5752 These functions are used by normal and router server to announce
5753 to its primary router about clients, channels and servers (when
5754 router) that we own. This is done after we've connected to the
5757 These functions effectively implements the following packet types:
5758 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5759 and SILC_PACKET_NEW_ID_LIST.
5761 * Added new functions into the silcd/packet_receive.[ch]:
5762 silc_server_new_id_list, silc_server_new_channel_list and
5763 silc_server_new_channel_user_list to handle the incoming
5764 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5766 * Added support of changing Channel ID in the function
5767 silc_server_replace_id. If the server that announces a channel
5768 to the router already exists in the router (with same name but
5769 with different Channel ID), router is responsible to send
5770 Replace ID packet to the server and force the server to change
5771 the Channel ID to the one router has.
5773 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5774 client that the Channel ID has been changed by the router. The
5775 normal server sends this to the client. Client must start using
5776 the new Channel ID as the channel's ID.
5778 Implemented handling of this new type into lib/silcclient/client.c
5779 into the function silc_client_notify_by_server.
5781 * Added new function silc_idlist_replace_channel_id into the files
5782 silcd/idlist.[ch] to replace the Channel ID.
5784 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5786 * Call silc_server_command_identify_check always when processing
5787 the IDENTIFY command in silcd/command.c
5789 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5791 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5792 send keepalive packets. The packet can be sent by clients,
5793 servers and routers.
5795 Added function silc_socket_set_heartbeat into the file
5796 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5797 If not set, the heartbeat is not performed. The actual
5798 heartbeat is implemented in the low level socket connection
5799 library. However, application is responsible of actually
5802 Added silc_server_send_heartbeat to send the actual heartbeat
5803 packet into silcd/packet_send.[ch]. Server now performs
5804 keepalive with all connections.
5806 * Added silc_task_get_first function into lib/silcutil/silctask.c
5807 to return the timeout task with shortest timeout. There was a bug
5808 in task unregistration that caused problems. TODO has been
5809 updated to include that task system must be rewritten.
5811 * The client library will now resolve the client information when
5812 receiving JOIN notify from server for client that we know but
5813 have incomplete information.
5815 * Rewrote parts of silc_server_remove_from_channels and
5816 silc_server_remove_from_one_channel as they did not remove the
5817 channel in some circumstances even though they should've.
5819 * Encryption problem encountered in server:
5821 The LEAVE command used to send the Channel Key packet to the
5822 router immediately after generating it. However, the code
5823 had earlier sent Remove Channel user packet but not immediately,
5824 ie. it was put to queue. The order of packets in the router
5825 was that Channel Key packet was first and Remove Channel User
5826 packet was second, even though they were encrypted in the
5827 reverse order. For this reason, MAC check failed. Now, this
5828 is fixed by not sending the Channel Key packet immediately but
5829 putting it to queue. However, this is more fundamental problem:
5830 packets that are in queue should actually not be encrypted
5831 because packets that are sent immediately gets encrypted
5832 actually with wrong IV (and thus MAC check fails). So, packets
5833 that are in queue should be encrypted when they are sent to
5834 the wire and not when they put to the queue.
5836 However, the problem is that the current system has not been
5837 designed to work that way. Instead, the packet is encrypted
5838 as soon as possible and left to the queue. The queue is then
5839 just purged into wire. There won't be any fixes for this
5840 any time soon. So, the current semantic for packet sending
5843 o If you send packet to remote host and do not force the send
5844 (the packet will be in queue) then all subsequent packets to the
5845 same remote host must also be put to the queue. Only after the
5846 queue has been purged is it safe again to force the packet
5849 o If you send all packets immediately then it safe to send
5850 any of subsequent packets through the queue, however, after
5851 the first packet is put to queue then any subsequent packets
5852 must also be put to the queue.
5854 Follow these rules and everything works fine.
5856 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * Added new function silc_server_remove_clients_by_server to
5859 remove all client entries from ID list when the server connection
5860 is lost. In this case it is also important to invalidate all
5861 client entires as they hold the invalid server entry. This
5862 fixes fatal bug when server has lost connection and will reconnect
5865 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5867 * Made some sanity checks to silc_server_daemonise like to check
5868 whether the requested user and group actually exists.
5870 * Added sanity check to SKE's silc_ske_responder_finish to check
5871 that the public and private key actually is valid.
5873 * Invalidate the client's nickname when receiving Replace ID
5874 packet and the Client ID is being replaced. This means that the
5875 server will query the nickname if someone needs it (client)
5878 * Sort the ID Cache in client library when the ID Cache data
5879 has changed (needs sorting).
5881 * Do not allow for SILC client to create several connections to
5882 several servers. The client does not support windows right now
5883 and generating multiple connections causes weird behaviour.
5885 Irssi-silc client does support windows and can handle several
5886 connections without problems, see: www.irssi.org and SILC plugin.
5888 * Fixed some places where client was added to the IDList. The
5889 rule of thumb is following (in order to get everything right):
5890 If the client is directly connected local client then the
5891 `connection' argument must be set and `router' argument must be
5892 NULL to silc_idlist_add_client function. If the client is not
5893 directly connected client then the `router' argument must
5894 bet set and the `connection' argument must be NULL to the
5895 silc_idlist_add_client function.
5897 * The funtion silc_server_packet_send_local_channel actually did
5898 not check whether the client was locally connected or not. It
5899 does that now. Fixed a bug related to LEAVE command.
5901 * Fixed Remove Channel User payload parsing bug in server's
5902 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5904 * The server's silc_server_save_channel_key now checks also the
5905 global ID list for the channel as it might not be in the local
5906 list. Fixed a bug related to LEAVE command.
5908 * Is this the end of the [<unknown>] buglet that has been lurking
5909 around for a long time? A little for loop fix in server's
5910 silc_server_command_whois_parse that is used by both IDENTIFY
5911 and WHOIS command. At least, this was a clear bug and a cause
5912 of one type of [<unknown>] buglet.
5914 * WHOIS and IDENTIFY commands call the function
5915 silc_server_command_[whois/identify]_check function even if
5916 we are not router server.
5918 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5920 * Added --with-gmp configuration option. If set the GMP
5921 is always compiled in the SILC source tree. If not set then
5922 it is checked whether the system has the GMP3 installed. If
5923 it has then the GMP won't be compiled (the system's headers
5924 and library is used), if it doesn't have it then the GMP is
5925 compiled in the SILC source tree.
5927 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5929 * Changed RSA private exponent generation to what PKCS #1
5930 suggests. We try to find the smallest possible d by doing
5931 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5932 not security fix but optimization.
5934 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5936 * Added new config entry [Identity] to fork the server and run
5937 it as specific user and group. A patch from Bostik.
5939 * Imported Dotconf configuration library into lib/dotconf.
5940 This will be used to create the SILC configuration files later.
5941 It will appear in the distsribution after this commit.
5943 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5945 * A big code auditing weekend happening. Auditing code for
5946 obvious mistakes, bugs and errors. Also, removing any code
5949 Removed files for being obsolete:
5951 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5952 inline in the file lib/silcutil/silcbuffer.h)
5954 o lib/silcutil/silcbufutil.c (the header has inline versions)
5956 Changed code to fix possible error conditions:
5958 o The buffer formatting routines now check that the destination
5959 buffer really has enough space to add the data. This applies for
5960 both buffer formatting and unformatting
5961 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5962 unformatting was changed to accomodate following rules:
5963 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5964 sent to the function while XXX_*STRING will not allocate or copy
5965 the data into the buffer. Instead it sets the pointer from the
5966 buffer into the pointer sent as argument (XXX_*STRING used to
5967 require that the pointer must be allocated already). This change
5968 makes this whole thing a bit more consistent and more optimized
5969 (note that the data returned in the unformatting with XXX_*STRING
5970 must not be freed now). The routines return now -1 on error.
5972 o Tried to find all code that use buffer_format and buffer_unformat
5973 and added return value checking to prevent formatting and
5974 especially unformatting errors and possible subsequent fatal
5977 o Changed ske->x and ske->KEY to mallocated pointers in
5978 lib/silcske/silcske.h. Fixed possible data and memory leak.
5980 o Added return value checking to all *_parse* functions. Fixed
5981 many memory leaks as well.
5983 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5984 so that buffer overflows would not happen. All code now also
5985 checks the return value as it can fail.
5987 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5989 * Added reconnection support to server if the normal server looses
5990 its connection to the router (for example if router is rebooted).
5991 The server performs normal reconnection strategy implemented
5992 to the server. Affected file silcd/server.c.
5994 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5996 * Added new packet type SILC_PACKET_SET_MODE that is used to
5997 distribute the information about changed modes (for clients,
5998 channels and clients channel modes) to all routers in the
5999 network. Updated the protocol specification accordingly.
6001 Added functions into silcd/packet_send.c and
6002 silcd/packet_receive.c: silc_server_send_set_mode,
6003 silc_server_set_mode.
6005 Added new files silcmode.[ch] into lib/silccore that implements
6006 the encoding and decoding of Set Mode Payload. Added new type
6007 SilcSetModePayload. Moved the definitions of different modes
6008 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6010 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6012 * Oops, a little mistake in server's connection authentication
6013 protocol. The protocol is not ended with FAILURE but with
6014 SUCCESS if the authentication is Ok. :) Affected file is
6017 * Implemented NICK_CHANGE notify handling in server in the file
6018 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6019 the local clients on the channel. After the changing nickname
6020 in router environment snhould work and the [<unknown>] nickname
6021 should appear no more.
6023 The silc_server_replace_id function that receives the Replace ID
6024 payload now sends the NICK_CHANGE notify type also in the file
6025 silcd/packet_receive.c
6027 * Changed WHOIS and IDENTIFY command to support the maximum amount
6028 of arguments defined in protocol specs (3328 arguments). This
6029 fixed a bug that caused problems when there were more than three
6032 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6034 * Added extra parameter, command identifier, to the
6035 silc_client_send_command so that explicit command identifier
6038 Changed that ID list routines uses specific command identifier
6039 when sending WHOIS/IDENTIFY requests to the server so that they
6040 can be identified when the reply comes back.
6042 Affected files lib/silcclient/command.[ch],
6043 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6045 * Added `sender' argument to silc_server_packet_send_to_channel
6046 to indicaet the sender who originally sent the packet to us
6047 that we are now re-sending. Ignored if NULL. Affected file
6048 silcd/packet_send.[ch].
6050 * Added some server statistics support in silcd/server_internal.h
6051 SilcServerStatistics structure and around the server code. Also
6052 send some nice statistics information when client is connecting
6055 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6057 * Fixed channel ID decoding in server's JOIN command reply in
6058 silcd/command_reply.c
6060 * Fixed braodcasting of replace ID payload to not to send it if
6061 we are standalone server in silcd/packet_receive.c.
6063 * Fixed all channel message sending routines to not to send
6064 packets to clients that has router set, since they are routed
6065 separately in the same function earlier. Affects file
6066 silcd/packet_send.c and all channel packet sending functions.
6068 * In USERS reply, res_argv[i] are not allocated, the table
6069 is allocated. Thus changed that free the table, not its
6072 * In server's whois_check and identify_check if the client is
6073 locally connected do not send any WHOIS commands - they are not
6076 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6078 * Fixed some minor bugs in client when sending WHOIS command. The
6079 arguments was in wrong order.
6081 * Removed statis function add_to_channel from server in
6082 silcd/command.c that was previously used with the joining but
6085 * Tested USERS command in router environment successfully with two
6086 routers, two servers and two clients.
6088 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6090 * Reorganized the USERS command and command reply in client library
6091 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6092 When the command is given by user we register a pending command
6093 callback that will reprocess the command after the reply has been
6094 received from the server. When reprocessing the packet we then
6095 display the information. Thus, the USERS information is displayed
6096 now in the command callback instead of in the command reply
6097 callback. The processing of the command is same as previously
6098 when server has sent the command reply in the JOINing process.
6100 * Added to USERS command in silcd/command_reply.c to join the client,
6101 we didn't use to know about, to the channel after we've created
6102 a client entry for it. Also, for clienet we did know already still
6103 check whether it is on the channel or not and add it if not.
6105 * Removed silc_server_command_join_notify as the function and its
6108 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6110 * Changed the client's pending command handling to the same as the
6111 server's pending command handling. It is also now possible to
6112 execute command reply functions from other command reply
6113 function as the function callbacks for commands and command
6114 replies are one and same. The pending commands are not static
6115 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6116 in client connection context. Thus, pending commands are server
6117 connection specific as it is convenient.
6119 Changed the function silc_client_command_pending and
6120 silc_client_command_pending_del and added new function
6121 silc_client_command_pending_check. Removed the
6122 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6125 * Added cmd_ident, current command identifier, to the client
6126 connection context in lib/silcclient/client.h to keep track on
6127 command identifiers used in command sending. Client's command reply
6128 function handling now supports the mandatory command identifiers.
6130 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6131 funtions in client to fully support pending command callbacks.
6133 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6134 as one of the arguments to the application in the command reply
6137 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6138 before first releasing SILC but came back. Now it is removed again
6139 and should come back nomore. The FORWARDED flag was used only
6140 by the JOINing procedure by forwarding the command packet to router.
6141 Now, the JOINing procedure has been changed to more generic (due
6142 to various router environment issues) and FORWARDED is not needed
6143 anymore for anything. The protocol specification is yet to be
6146 Now, removed silc_server_packet_forward from server and the flag
6147 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6149 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6151 * Renamed NAMES command to USERS command. The NAMES was named that
6152 due to historical reasons. Now it is renamed. Also, rewrote
6153 parts of the USERS command. The nickname list is not sent anymore
6154 by the server. Only Client ID and mode lists are sent in the USERS
6155 command. Changed this also to the protocol specification.
6157 The client now resolves the names and stuff after it receives
6158 the USERS list from the server when joining to the channel.
6160 * WHOIS and IDENTIFY commands has been changed to support multiple
6161 Client ID's per command. One can now search for multiple users
6162 in the network by sending only one WHOIS or IDENTIFY command.
6163 Changed the code and the protocol specifications.
6165 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6166 uses silc_server_command_whois_parse to parse the request. */
6168 * If normal server, do not parse the WHOIS and IDENTIFY requests
6169 before sending it to the router. Saves some time.
6171 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6173 * Fixed JOIN command on client library. Wrong number of arguments
6174 used to crash the client.
6176 * Added silc_server_channel_has_global function to check whether
6177 channel has global users or not.
6179 * Added silc_server_channel_has_local function to check whether channel
6180 has locally connected clients on the channel.
6182 * The silc_server_remove_from_one_channel now checks whether the
6183 channel has global users or not after given client was removed from
6184 the channel. It also checks whether the channel has local clients
6185 on the channel anymore. If it does not have then the channel entry
6186 is removed as it is not needed anymore.
6188 * The silc_server_notify now checks on JOIN notify whether the joining
6189 client is one of locally connected or global. If it is global then
6190 the channel has now global users on the channel and that is marked
6191 to the channel entry. Also, it now saves the global client to
6192 global list who is joining and JOINs it to the channel. This is
6193 for normal server, that is.
6195 Changed silc_server_send_notify_on_channel,
6196 silc_server_packet_relay_to_channel and
6197 silc_server_packet_send_to_channel check if we are normal server
6198 and client has router set (ie. global client) do not send the
6199 message to that client, as it is already routed to our router.
6201 * Implemented LEAVE notify type handling in silc_server_notify
6204 * Tested LEAVE command in router environment successfully. Tested
6205 with two routers, two servers and two clients.
6209 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6211 * Implemented SIGNOFF notify type handling in silc_server_notify
6214 * silc_server_remove_id now removes the client entry from all channels
6215 it has joined and thusly sends SIGNOFF notify type.
6217 * Rewrote the NAMES list generation in server by removing two excess
6218 loops. The lists are created now inside one loop.
6220 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6222 * silc_server_remove_channel_user checks now also global list
6223 for channel and client.
6225 * silc_server_new_channel_user checks now both local and global
6226 list for channel and client. Fixed a bug in client id decoding.
6227 Used to decode wrong buffer.
6229 * silc_server_channel_message checks now both local and global
6230 list for channel entry.
6232 * Tested channel joining (hence JOIN) in router environment
6233 successfully. Tested with two routers, two servers and two
6236 * Tested channel message sending in router environment successfully.
6238 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6240 * Added silc_server_save_channel_key into server.[ch] to save the
6241 received channel key in Channel Key payload processing. It is
6242 also used in JOIN command reply handling.
6244 Equivalent function silc_client_save_channel_key added into
6245 client.[ch] into client library.
6247 * Changed JOIN command reply to send information whether the channel
6248 was created or not (is existing already) and the channel key
6249 payload. Changed protocol specs accordingly.
6251 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6252 the request was sent by ID and not by nickname. Crashed on
6255 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6257 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6258 now correctly save the received data.
6260 * silc_server_free_sock_user_data now notifies routers in the
6261 network about entities leaving the network.
6263 At the same time implemented functions silc_server_remove_id
6264 and silc_server_send_remove_id to receive and send REMOVE_ID
6265 packets. The packet is used to notify routers in the network
6266 about leaving entities. The ID removed will become invalid in
6269 * Added function silc_idlist_del_server into server. Removes and
6270 free's server entry from ID list.
6272 * silc_server_private_message function now checks, if we are router,
6273 that the destination ID really is valid ID, naturally.
6275 * In router when NEW_ID packet is received (for new client) the
6276 hash of the Client ID is saved in the ID Cache but the
6277 client->nickname is set to NULL, instead of putting the hash
6280 IDENTIFY command now also checks that client->nickname must be
6281 valid. If it is not if will request the data from the server who
6282 owns the client. Added new function
6283 silc_server_command_identify_check.
6285 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6286 to set the command to already allocated Command Payload.
6288 * Tested private message sending in router environment with two
6289 routers, two servers and two clients. Fixed minor bugs and now
6292 * Fixed segfault from client's NAMES command. Used to crash if
6295 * Forwarded packets must not be routed even if it is not destined
6296 to the receiver. Changed server code comply with this.
6298 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6300 * Added `require_reverse_mapping' boolean value to ServerParams
6301 structure. If TRUE (not default) the server will require that
6302 the connecting host has fully qualified domain name.
6304 If the reverse mapping is not required and hostname could not be
6305 found the IP address is used as hostname.
6307 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6309 * Implemented version string checking to both client and server.
6310 The check is incomplete currently due to the abnormal version
6311 strings used in development version of SILC.
6313 * Changed all command functions in server to use the new
6316 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6318 * Changed char *data to unsigned char *data in ID Cache system to
6319 support binary data as ID Cache data. Changed code to support
6320 binary data in lib/silccore/idcache.c.
6322 * Renamed silc_server_packet_relay_command_reply to
6323 silc_server_command_reply as it is normal packet receiving
6324 function. Rewrote the function to accept command replys for
6325 servers and not only for clients.
6327 * Mark remote router always as registered server if we are connecting
6328 to it. Otherwise, commands sent by the router to us are ignored.
6330 * All ID List find routines now returns the ID Cache Entry pointer
6331 as well if requested.
6333 * WHOIS command works now in router environment, tested with two
6334 routers, two servers and two clients.
6336 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6337 in router environment (as it is almost equivalent to WHOIS) but
6338 hasn't been tested thoroughly. Added new functions:
6340 silc_server_command_identify_parse
6341 silc_server_command_identify_send_reply
6342 silc_server_command_identify_from_client
6343 silc_server_command_identify_from_server
6345 * Disabled route cache adding because adding two different ID's with
6346 same IP replaces the old cache entry thus giving wrong route.
6347 The entry->router->connection is always the fastest route anyway
6348 so route cache may not be needed. Of course, new routes maybe
6349 established after receiving the ID when the entry->router->connection
6350 might not be anymore the most optimal.
6352 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6354 * Add route cache for received ID for fast routing.
6356 * Added silc_server_packet_route to route received packet on router
6357 that is not destined to us.
6359 * Renamed silc_server_get_route to silc_server_route_get.
6361 * Added id_string and id_string_len fields into SilcServer to
6362 include encoded ServerID for fast comparing without excess
6363 encoding of the ID's.
6365 * Cleaned up WHOIS command on server side. Added following static
6368 silc_server_command_whois_parse
6369 silc_server_command_whois_check
6370 silc_server_command_whois_send_reply
6371 silc_server_command_whois_from_client
6372 silc_server_command_whois_from_server
6374 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6375 arguments in command replies. All command functions should be
6376 updated to use this macro.
6378 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6380 * Minor typo fixes on command reply handling on server.
6382 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6384 * Added silc_server_command_add_to_channel internal routine to add
6385 the client to the channel after router has created the channel and
6386 sent command reply to the server.
6388 * Added generic silc_server_send_command to send any command from
6391 * Use static buffer with ID rendering instead of duplicating data.
6393 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6395 * Fixed a channel user mode bug when joining to a channel server gave
6396 everybody channel founder rights, oops.
6398 * We mark ourselves as the router of the incoming server connection
6399 if we are router ourselves. This way we can check in some packet
6400 sending functions whether it is locally connected server. For
6401 incoming router connections we put NULL.
6403 * For router sending packets locally means now always sending the
6404 packet cell wide; to local clients and local servers. For normal
6405 server sending packet locally means sending it to only local
6408 * Fixed the JOIN command to really work in router environment. If the
6409 channel is created it is always created by the router. Router is
6410 also responsible of making the initial joining to the channel,
6411 sending JOIN notify to the sending server and distributing
6412 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6413 does not exist server doesn't do anything else but forward the
6414 command to the router which performs everything.
6416 * Added silc_server_send_channel_key function to send the Channel Key
6419 * Added silc_server_create_channel_key to create new channel key. The
6420 channel key is now re-generated everytime someone joins or leaves
6421 a channel, as protocol dictates. Note: channel->key_len is the
6424 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6426 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6427 packet_receive.[ch] to separate packet sending and receiving
6428 routines. The server.[ch] now includes everything else including
6429 actual packet processing (writing and reading data) and other
6432 Renamed silc_server_private_message_send_internal to
6433 silc_server_send_private_message. The routine is still though
6434 used only to relay private messages as server does not send
6435 private messages itself.
6437 Renamed silc_server_new_channel to silc_server_create_new_channel
6438 and added new function sicl_server_new_channel that handles the
6439 incoming New Channel packet. Added also new sending function
6440 silc_server_send_new_channel to send New Channel Payload.
6442 * Added new function silc_server_notify to process incoming notify
6443 packet to the server/router. Server may then relay the notify
6444 to clients if needed.
6446 * Added new function silc_server_new_channel_user to process incoming
6447 New Channel User packet. Router will redistribute the packet and
6448 send JOIN notify to its local clients and locally connected servers
6449 if needed. Normal server will send JOIN notify to its local client
6450 on same channel when received this packet. Added also corresponding
6451 sending function silc_server_send_new_channel_user to sent the
6454 * Added boolean route argument to send_notif_to_channel and
6455 packet_send_to_channel functions to attempt to route the packet
6456 if it is TRUE and send only locally if it is FALSE.
6458 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6460 * silc_server_replace_id now broadcasts the received replace ID
6461 packet if it is not broadcast packet already. The router must
6462 broadcast to inform other routers about changed ID.
6464 * Added backpointer to server's router into SilcServer context in
6465 silcd/server_internal.h.
6467 * Fixed silc_server_packet_broadcast to send correct broadcast
6470 * The channel key is now distributed to the local client as soon
6471 as it is received from the router (in router environment) so that
6472 no other packet may be sent for the channel until client has
6475 * silc_server_remove_channel_user now broadcasts the received
6476 Remove Channel User packet if it is not broadcast packet already.
6477 The router must broadcast to inform other routers about removed
6480 * Added users field into SilcPacketContext that is a reference count
6481 of the context. One can increase the reference count by calling
6482 silc_packet_context_dup which is now changed to just increase the
6483 reference count instead of duplicating the data. The reference
6484 count is decresed by calling silc_packet_context_free that will
6485 free the data after the reference count hits zero.
6487 For now on the packet context and everything allocated into it
6488 (including the raw packet from network) must be freed by calling
6489 the new silc_packet_context_free function. Added also new function
6490 silc_packet_context_alloc that must be used now to allocate the
6491 context. This also means that if a routine is asynchronous from
6492 silc_[client/server]_packet_parse_type the packet context must
6493 be duplicated by calling silc_packet_context_dup. Otherwise it
6494 gets free'd after silc_[client/server]_packet_parse_type returns.
6495 Also, one must remember that if packet is duplicated then its
6496 reference count must be decresed by calling the free function as
6497 many times as it was duplicated.
6499 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6500 from both client and server.
6502 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6504 * Made joining to a channel working in router environment.
6506 * Cleaned up JOIN command on server side and create function
6507 silc_server_command_join_channel internal routine to make the
6510 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6512 * Changed silc_command_pending list to SilcDList. Also, added
6513 `ident' field to SilcServerCommandPending structure to identify
6514 the reply and to call correct callback.
6516 Added silc_server_command_pending_check function to replace the
6517 corresnponding macro. The silc_command_pending list is not
6520 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6521 to set identifier to previously allocated Command Payload. It
6522 is used to set identifier for command when resending Command
6525 * Added silc_command_payload_encode_payload to encode Command
6526 Payload buffer from SilcCommandPayload structure.
6528 * Added silc_argument_payload_encode_payload to encode Argument
6529 payload buffer from SilcArgumentPayload structure.
6531 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6533 * Changed WHOIS command to support router connection on server side.
6534 The whois request is always sent to router unless the server is
6535 standalone server. After server has received the reply from the
6536 router will it send the reply to the client.
6538 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6539 broadcast received broadcast packet. The function is used only
6540 by router. The broadcast packet is always sent to the router's
6543 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6544 render given ID to printable string, for log files for example.
6546 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6548 * Made basic router to router connections working. At least they
6549 can now connect to each other but nothing really works the way
6550 they are supposed - yet.
6552 * Added new initiator token to RouterConnection configuration
6553 file in silcd/serverconfig.[ch]. It is used to tell whether we
6554 are the initiator to the remote router or whether we'll expect
6555 the other end to connect.
6557 * Moved registering of listener task to silc_server_init, hence
6558 the server starts listenning as soon as it is run, even if it
6559 does not have connections to other routers. Let's see how well
6562 * Changed default connection retry timeouts for more suitable in
6565 * Removed cipher and such arguments from silc_idlist_add_client
6566 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6567 Added new function silc_idlist_add_data to add the keys and stuff
6570 * Added SilcIDListData structure and added it to SilcClientEntry
6571 and SilcServerEntry as their first field in the structure. This
6572 way we can explicitly cast the ID entries to the SilcIDListData
6573 structure and get common data for the entries. In past, we had
6574 to first check what type of connection it is and then cast it to
6575 correct ID entry type. Now, we can directly cast the opaque
6576 pointer to the SilcIDListData (no matter what ID entry it actually
6577 is) and get the data needed.
6579 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6581 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6582 in some circumstances even if threre were timeout tasks, though not
6583 IO tasks, but tasks anyway. Now fixed.
6585 * Defined SilcServerConnection structure to hold connection specific
6586 stuff about directly connected servers and routers. The definition
6587 is currently in silcd/server_internal.h. I thought about having
6588 a bit more important role fro this struct but for now it is used
6589 only when connecting to other server (or router actually).
6591 * Added connecting retry support in server when connecting to
6592 router(s). The retry feature implement exponential backoff
6593 algorithm. Also, added SilcServerParams structure to hold default
6594 parameters for server. For now, it include these retry settings
6595 and are hard coded. After server is moded to be as Silc Server
6596 Library this structure will be more important.
6598 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6600 * Changed client librarys channel->clients table to SilcList and
6601 changed code accordingly.
6603 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6605 * Changed client's channel table to SilcList and changed code
6606 accordingly. Also changed SilcChannelClientEntry to include back-
6607 pointer to the channel so that client entry can use that structure
6608 as list as well and we have fast cross-reference to the channel.
6609 This change dramatically decreased the complexity of channel
6610 handling with client entry and vice versa (removed one extra
6611 loop when searching for channel entry from many functions).
6613 * Changed server->sim from table to SilcDList and changed code
6616 * NAMES command can now be used from user interface. It will show
6617 the user list on the channel, neatly.
6619 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6620 Code now saves realname of the user if it becomes available.
6622 * Renamed configure.in to configure.in.pre and made ./prepare
6623 script to automatically add correct version string to
6624 configure.in which it creates from configure.in.pre.
6626 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6628 * NAMES command reply now shows users mode with the nickname when
6631 * Moved silc_client_ch[u]mode[_char] functions from
6632 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6633 place sucks, they are utility functions and should be in some
6636 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6638 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6641 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6645 * Added TRQ (efficient deque and list library) into lib/trq. This is
6646 a very good list library that is currently used in the SILC. Defined
6647 SilcList API over the library because I didn't like the API very
6648 much. See lib/trq/silclist.h for the API and examples of how to
6649 use the API. Fixed various places in the code to use the new
6650 SilcList API. The SilcList is meant for lists that has a structure
6651 already defined as a list. It is not suitable to add just some
6652 context to the list (in TRQ, the context is the list actually).
6654 So, I defined SilcDList that can be used for the purpose where
6655 predefined list structure does not exit. This can be used as
6656 such list. Now some context just can be added to the SilcDList.
6657 Currently this list is not used in the SILC just yet, though there
6658 are a lot places where this can replace dynamically allocated
6659 tables and I will fix these places, later, to use SilcDList.
6660 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6661 and use TRQ internally).
6663 Also fixed some annoying warning messages that the original TRQ
6664 code generated. Also minor changes to TRQ's Makefile.in.
6666 * Added support for querying by Client ID to both WHOIS and
6667 IDENTIFY commands into server, as required by the protocol.
6669 * Removed method function pointers from SilcBuffer structure. They
6670 weren't used to anything and just increased the context size for
6671 no good reason. This change also made silc_buffer_alloc and
6672 silc_buffer_free functions inline functions.
6674 * Disabled command flooding detection support until it's fixed so
6675 that it accepts commands in but does not execute them more than once
6678 * Added silc_net_localhost(), to return local hostname, into
6679 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6680 that must be initialized before calling silc_client_init.
6682 * Added new function: silc_server_send_notify_on_channels to send
6683 notify messages to all channels client has joined. It is assured
6684 that the message is sent only once per client.
6686 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6687 lib/silcutil/silcutil.[ch] as silc_format function. The new
6688 function is generic and is used by server as well, not only by
6689 the logging routines.
6691 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6692 the provided version string was not acceptable. Added new function:
6693 silc_ske_check_version into lib/silcske/silcske.h. The function
6694 must be implemented by the application (client or server) and it
6695 does not reside in the SKE library. The function checks the version
6696 string remote end sent.
6698 * Added back pointers (to opaque context and to SilcSocketConnection)
6699 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6701 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6702 duplicate packet context structure.
6704 * Changed `notify' client operation to send same arguments as client
6705 receives from server except for ID's. ID's are mapped to correct
6706 ID entry and that is returned. Also, if channel entry is not sent
6707 by server but the notify is for channel the channel entry is sent
6708 to application (otherwise application doesn't know that it is for
6709 channel (library gets it from packet's Destination ID)).
6711 * Added silc_client_remove_from_channels into client library to
6712 remove a client from all channels it has joined to. Used when
6713 received SIGNOFF notify from server. Added also new function
6714 silc_client_replace_from_channels to replace old ID entry with
6715 new ID entry on all channels. Used when received NICK_CHANGE
6718 * Fixed ID Cache list handling in silc_idlist_get_client in
6719 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6720 to get (or query) client by ID.
6722 * Updated TODO list.
6724 * Added connection authentication status message defined by the
6725 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6726 support for these into the code in client and server side.
6728 * Added generic function silc_client_send_command to send any command
6729 with variable argument list. Application should use this function
6730 to send commands if the command functions provided by the library
6731 does not suite for the application's user interface needs.
6733 * Added new `failure' client operation. Application is notified about
6734 received failure packet if client is executing a protocol. In this
6735 case the protocol's execution has failed.
6737 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6738 is required by the protocol.
6740 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6741 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6744 * Added status flag to SilcSKE object to indicate realtime status
6745 of the SKE protocol.
6747 * Application receives now exactly same command reply arguments as
6748 the library receives from server. However, if ID is received the
6749 corresponding ID entry is returned to the application (eg. Client
6750 ID is mapped to correct SilcClientEntry entry and that is returned).
6751 Changed command_reply client operation due to this change.
6753 * Changed all ID's in commands and in command replys as ID Payloads.
6754 Change affected both client and server side codes.
6756 All ID's sent in SILC network (with execption of ID's in SILC
6757 Packet header) are sent in ID Payload to support variable length
6760 * Server now notifies nick changes and notifies all clients on
6761 the channels about the new nickname (about the new Client ID,
6764 * Implemented CMODE command to change channel modes. Supports all
6765 channel modes defined by the protocol specs except ban and invite
6766 lists. (Also, private channel key mode is supported but support for
6767 setting private channel key in client is missing, thus, this mode
6768 has no effect on client side (except that server requires that the
6769 client uses private channel key and normal channel traffic does not
6772 Also, invite mode works per se, but INVITE command does not work
6773 yet correctly, so you can set channel as invite only channel but
6774 inviting clients to the channel does not work (it is yet to be
6775 thought what's the best way to do it).
6777 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6778 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6779 Implemented CUMODE command to change user's mode on the channel.
6780 Supports all modes defined by the protocol specs.
6782 * Added NAMES command reply to return users modes on the channel.
6784 * Removed unnecessary and slow ciphers from lib/silccrypt.
6786 * Set SO_KEEPALIVE option to connection sockets by default.
6788 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6790 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6791 redefined the Notify Payload into protocol specs.
6793 * Added silc_id_payload_parse_id to get ID directly from raw
6796 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6798 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6799 accept searching by Client ID as well.
6801 * Added support for LEAVE and SIGNOFF notify types in client library.
6803 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6804 to parse ID Payload from raw data.
6806 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6808 * Added flags parameter into silc_ske_assemble_security_properties
6809 function in lib/silcske/silcske.[ch].
6811 * Changed notify client operation to fit better for notify messages
6812 sent by server. The notify payload received from server is now
6813 passed to the application (after parsing it to SilcNotifyPayload).
6814 It is application's responsibility to retrieve the arguments
6815 from the payload and show the message the way it wants. The message
6816 sent by server is implementation specific.
6818 * Changed public keys to comply with the protocol specification.
6819 Old public keys are not supported anymore and are not compatible.
6821 * Removed nickname from Channel Payload as the latest draft removed
6822 it. The client must resolve the nickname from the NAMES command
6823 reply received when it joined the channel.
6825 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6827 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6829 * Fixed some errors in protocol specification drafts.
6831 * Created lib/silccore/silcnotify.c to implement Notify Payload
6832 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6833 generic payloads described by protocol specifications. The file
6834 includes implementations for ID Payload and Argument Payload.
6836 * Changed Command Payload implementation to use the new Argument
6837 Payload. Changed command_xxxx_payload to command_payload_xxxx
6838 to comply with SILC coding conventions.
6840 * Added suppport for Argument Payload handling in Notify Payload
6841 implementation as protocol requires it. Added the new support
6842 into server and client lib as well.
6844 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6846 * Added support for multiple nicknames on same channel. [n] is
6847 added locally to the nickname if there are more than one same
6848 nicknames on the channel.
6850 * Server now sends all nicknames that matched WHOIS request.
6851 Client also shows the list received from server.
6853 * Added TOPIC command to client side. User can now set and show
6854 current topic on channel.
6856 * Added MOTD command to client and server. Also, server sends the
6857 motd when client connects to the server.
6859 * Changed version strings to comply ISO 8601.
6861 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6863 * Fixed protocol error handling in client library. It should now
6864 cope even if the SKE fails for some reason.
6866 * Made new protocol specification drafts for submitting to IETF.
6868 * Implemented TOPIC command to server in silcd/command.c.
6870 * Added two new notify types into lib/silccore/silcnotify.h:
6871 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6872 notify nickname change and topic setting/change on a channel.
6874 * API change of command_reply operation in client library. The
6875 application gets now the status type received from server as well.
6877 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6879 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6881 * Cras fixed and optimized the packet handling even further and
6882 it should work now. Minor change to the prototype of function
6883 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6885 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6887 * Added new function into lib/silcutil/silcschedule.[ch]:
6888 silc_schedule_with_fd to select() a specified fd. The function
6889 returns after timeout expires or data arrives or goes. The
6890 function is used by packet routines to wait that all data is
6891 received from network.
6893 * Fixed data reading from network in lib/silccore/silcpacket.c.
6894 The code now assures that all data is read from the fd and then
6895 continues packet processing. This was a bug fix since the code
6896 used to drop some data in some circumstances.
6898 * Added new function into lib/silcclient/client.[ch]:
6899 silc_client_start_key_exchange to start key exchange after
6900 connection has been established to server. The code internally
6901 now uses this funtion but its main purpose was to provide it
6902 for applications that perform their own connecting. After
6903 application has created a connection it merely calls this
6904 function to start the key exchange between client and server.
6905 The library takes care of everything else after that.
6907 Updated also lib/silcclient/README to explain the usage of
6910 * Do not send to application information that connection has
6911 been established. Application gets notified it by connect
6914 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6916 * Applied cras's patch to add silc_schedule_one function. The
6917 function runs scheduler once and returns.
6919 * Fixed the scheduler after cras messed it up. The timeout
6920 handling works now as it's supposed to work.
6922 * Added into lib/silccore/ silcnotify.h to include notify
6923 message types support. Changed silc_server_send_notify*
6924 functions, in server.[ch], to support those new notify types.
6925 Added the support for the notify types into client library,
6926 as well. Added new notify client operation into ops.h in
6929 * Changed silc_server_packet_send_to_channel to send normal
6930 packets instead of just channel message packets. The function
6931 is now used to send the notify packets to channels. It is not
6932 used to send channel message packets anymore, as server never
6935 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6936 va_arg()s as it seems to require it nowadays. I guess, if SILC
6937 is compiled with older va_arg() the new code should work anyway.
6939 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6941 * Splitted core library. Core library (lib/silccore) includes
6942 now only SILC protocol specific core (and common) components.
6943 Created new utility library (lib/silcutil) that includes more
6944 generic purpose stuff. The stuff for util library was taken
6945 from the old core library. This was minor and easy split.
6947 * Created SILC Client Library (lib/silcclient) that includes
6948 implementation of the SILC client without user interface. This
6949 was major move from silc/ directory. The code has been changed
6950 so that it is transparent towards the user interface. The
6951 silc/ directory includes now the same user interface as before
6952 and it uses the new client library. Read lib/silcclient/README.
6953 Basicly, the client library performs everything else related
6954 to SILC except user interface handling. Also, configuration
6955 files are considered to be part of user interface and library
6956 does not handle them.
6958 This change also changed a lot of structures, function naming etc.
6959 Most important change was that SilcClientWindow object was
6960 renamed to SilcClientConnection in the client library. Created
6961 also new file lib/silcclient/ops.h. Also added new files
6962 silc/local_command.[ch] and silc/client_ops.[ch].
6964 All these changes were made to make it easier for user interface
6965 designers to create what ever user interface for the SILC client
6968 It is also expected that the server will be moved to lib
6969 directory as well and SILC Server Library will be created;
6970 sometimes in the future.
6972 * Removed Local commands from lib/silccore/silccommand.h as
6973 they are application specific and new client library does not
6974 handle any of those anymore.
6976 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6977 old client implementation in silc/.
6979 * Added support for callback functions in SILC_LOG_* macros.
6980 Application can now set its own callbacks that will be called
6981 instead of using the default functions that will always print
6982 the debug messages to stderr (or stdout). Also, debugging can
6983 now be disabled by setting silc_debug to FALSE and re-enabled by
6984 setting it to TRUE. Note, that logging will still work even
6985 if debugging is disabled.
6987 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6988 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6989 silc_log_reset_debug_callbacks.
6991 * To enable debugging in silc client one must give now -d
6992 option on command line.
6994 * Changed silc_schedule_init to automatically allocate task queues
6995 if they are not allocated before calling it.
6997 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6999 * Added GMP 3.1 into math library.
7001 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7003 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7004 a channel in SILC network. The packet is used by servers and
7005 routers to notify other routers that user has left a channel.
7006 This little feature was missing until now. Added the feature
7007 to protocol specification as well.
7009 Added functions: silc_server_send_remove_channel_user and
7010 silc_server_remove_channel_user into server.[ch].
7012 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7013 lib/silccore/silcpacket.h. However, they are not implemented
7016 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7018 * Fixed joining to a channel and sending channel messages
7019 between server and router. The channel message sending should
7020 now work inside a cell.
7022 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7024 * Fixed the private message sending between server and router.
7025 The private message sending should now work inside a cell.
7027 * Added silc_server_replace_id into server.[ch] to replace
7028 existing ID in the SILC network.
7030 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7031 and silc_idlist_replace_server_id into idlist.[ch] in server.
7033 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7035 * Fixed the server to server connections. Server can again now
7036 connect to router. Router to router connections probably does
7039 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7041 * Added dynamic protocol registering support. Now protocols can
7042 registered and unregistered on the fly. Patch by cras.
7044 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7046 * Added lib/contrib directory to hold routines that some platforms
7047 don't have but are needed by SILC.
7049 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7050 into lin/contrib to provide getopt() and getopt_long() for
7051 those who don't have it.
7053 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7055 * Added AWAY command to client. When away message is set and
7056 client receives a private message packet the client automatically
7057 replies to the sender with the away message.
7059 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7060 bug seemed to be the cause of recent problems when compiling
7063 * Added version detection support to SKE protocol specification
7064 and added the new changes to the SKE implementation as well.
7065 There were other minor changes in the SKE protocol as well.
7067 Many changes in lib/silcske/silcske.[ch] and in
7068 lib/silcske/payload.[ch].
7070 * Added ^U functionality, clear input line. Patch from cras.
7072 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7074 * Mainly small bugfixes on core library. Fixed some debugging
7075 logging and buffer overflow in silclog.c.
7077 * Updated config.sub and config.guess on the distribution tree.
7079 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7081 * Added command lagging support in server. Client may execute
7082 commands now only once in two seconds.
7084 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7086 * Optimized packet reception. MAC computation and checking is now
7087 also more optimized. A lot previously duplicated code is now
7088 used as generic by both client and server.
7090 * Fixed key pair generation in clientutil.c
7092 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7094 * Added into lib/silccore/silcbufutil.[ch] new function;
7095 silc_buffer_realloc.
7097 * Moved generic packet sending/encryption functions to
7098 lib/silccore/silcpacket.[ch] from client and server. Some
7099 rewriting of the functions.
7101 * Moved all generic packet reception/decryption functions to
7102 lib/silccore/silcpacket.[ch] from client and server. The
7103 packet processing is now much cleaner in both client and server.
7104 These were major changes in both client and server.
7106 * Created many common functions in server to do packet sending.
7107 Previously code were duplicated a lot, this has been removed
7110 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7112 * Rewrote major parts of the ID cache system. Don't know
7113 whether it is better now or not but at least the API is more
7116 * Major rewrite on ID cache stuff on client because of the ID
7117 cache API changes. Added idlist.c to client.
7119 * Also major rewrite on ID cache stuff on server as well.
7120 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7121 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7122 in hand, instead they are all put into the ID cache system now.
7123 All server_idlist_* routines uses ID cache now instead of
7124 traversing its own lists (those lists does not exist anymore).
7125 SilcIDList though still exists. Also, SilcXXXEntry's are
7128 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7130 * Finally made the SKE implementation compliant to the protocol
7131 specification. All mp integers are now binary encoded as
7132 opposed being HEX encoded.
7134 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7137 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7138 functions: silc_[encode/decode]_pem. Also added function
7139 silc_encode_pem_file to PEM encode with newlines ('\n') for
7142 * SILC public keys are now encoded either PEM or binary. Same
7143 option is for private keys as well. By default private keys
7144 are binary encoded and public keys PEM encoded. Silly HEX
7145 encoding were removed.
7147 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7148 function to create fingerprints.
7150 * Fixed a bug in SHA1; does not change the original data anymore.
7152 * Partly implemented INFO command on client and server side.
7153 Fixed CLEAR command. Changes to SERVER command; show current
7154 server(s) when giving command without arguments. Added
7155 VERSION command to client.
7157 * Added check to server that unregistered connections cannot
7158 execute commands (unless it is specificly allowed).
7160 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7162 * Fixed screen refresh.
7164 * Fixed channel joining bug from client. On some circumstances
7165 client tried to join to a channel it had already joined.
7167 * Added public key verification process into client's protocol.c.
7168 The client now verifies the public key from user and saves
7169 it into ~./silc/serverkeys/ directory.
7171 Added into: clientutil.[ch]: silc_client_verify_server_key.
7173 * Changed SKE protocol's silc_ske_initiator_finish function
7174 to accept callback function that verifies the received public
7175 key. Removed old silc_ske_verify_public_key function.
7177 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7179 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7180 silc_pkcs_private_key[_data]_set.
7182 * Made the password and public authentication more cleaner in
7183 server's protocol.c.
7185 * Removed historic and obsolete protocol `channel_auth' from
7186 both client and server.
7188 * Removed wrong way of sending command status messages from
7189 server to client in server's command.c. The old way violated
7190 protocol specification.
7192 Changes to silccore/silccommand.[ch]: removed
7193 silc_command_encode_status_payload -> not needed anymore,
7194 changed silc_command_encode_payload_va to accept extra
7195 argument on variable argument list. The argument type must
7196 now be provided to the function. Also, added new function:
7197 silc_command_encode_reply_payload_va which is same as
7198 normal command_encode_payload_va except command status type
7199 is provided as extra argument.
7201 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7203 * Added ~./silc directory handling. The directory includes the
7204 public and private keys for the client.
7206 Added silc_client_check_silc_dir, silc_client_create_identifier
7207 and silc_client_load_keys.
7209 * Implemented SILC protocol compliant public key. Added public
7210 and private key saving to and loading from files.
7212 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7213 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7214 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7215 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7216 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7218 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7219 silc_pkcs_load_[public/private]_key.
7221 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7223 * Added silc_server_get_route (route.[ch]) to get connection
7224 data for the fastest route for given ID.
7226 * Implemented INVITE command on client and server. The command
7227 were re-defined in the SILC Protocol Specification and the
7228 implementation now complies with the specification.
7230 * Implemented PING command on client and server.
7232 * Implemented NAMES command on client and server. The server side
7233 supports currently only normal server not router server yet.
7234 Some changes to NAMES definition in SILC protocol specification.
7236 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7238 * Implemented LEAVE command on client and server.
7240 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7241 again. This change was made to the protocol as well. Server
7242 should not violate the protocol specification anymore.
7244 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7246 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7247 was tested. SOCKS4 was not but should work anyway.
