1 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Added automatic extern "C" { ... } for C++ compilers so the
4 application does not need to define them. Affected file
5 includes/silcincludes.h.
7 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
8 old name went against naming convention. Applications now
9 include "silcclient.h" instead of "clientlibincludes.h".
10 Removed includes/clientlibincludes.h, it is redundant now.
12 * Renamed includes/version.h to silcversion.h.
14 * Added really preliminary support for OS/2 into the util
15 library. Only thread & mutex API is implemented, others
16 are still to be implemented. Created the lib/silcutil/os2/
17 directory. Created also file includes/silcos2.h.
19 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

23 functions to support SILC on BeOS. Created also file
26 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
28 * Added proper initializations to silc's irssi code, so it's
29 now possible to load it as module. Affected files
30 irssi/src/silc/core/silc-core.c,
31 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
33 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>

42 * ROBOdoc documented lib/silcutil/silcmemory.h.
43 Added also new function silc_memdup.
45 * Removed lib/silcutil/silcbufutil.h and moved those routines
46 to the lib/silcutil/silcbuffer.h.
48 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
50 * Added `user_count' to the SilcChannelEntry which now tells the
51 number of users on the channel. The user count is now saved
52 in normal server of global channels as well. Affected files
53 silcd/server.c, idlist.h, packet_receive.c and command.c.
55 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to

67 Affected file lib/silcclient/client.c.
69 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
71 * ROBOdoc documented the lib/silcske/silcske.h, and improved
72 the SKE interface a bit.
74 * Fixed padding problem in PKCS#1. The padding was not actually
75 random since the random number generator was used incorrectly.
76 This security bug affects only when encrypting with PKCS#1, and
77 it is not currently used at all in SILC. SILC only use signing
78 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
80 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

144 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
146 * Added new configuration options and blocks:
147 keepalive_secs, reconnect_count, reconnect_interval,
148 reconnect_interval_max, reconnect_keep_trying and
149 require_reverser_lookup. Added ConnectionParam block, and
150 implemented the connection parameters when connecting as
151 initiator and when accepting connections as responder.
153 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
154 whether given configuration value has been given already.
156 Affected files silcd/serverconfig.[c], server.[c].
158 * Splitted the doc/example_silcd.conf.in. Separated the crypto
159 algorithm parts and created new file silcalgs.conf, that
160 is now included from the example_silcd.conf.in.
162 * Optimized the silc_server_connect_to_router_second to take
163 the connection configuration object from the SilcServerConnection
164 object instead of finding it during the connecting phase.
165 Added the configuration object to SilcServerConnection struct.
166 Affected files silcd/server_internal.h, server.c.

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

246 hash algorithm. Affected file lib/silccrypt/silcrng.c.
248 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
250 * Fixed the file transfer's key agreement payload to include
251 zero port also if the hostname is NULL because it could not
254 Call file transfer monitor callback now also if error occurs
255 during key agreement protocol.
257 Changed the silc_client_file_send interface to return the
258 SilcClientFileError instead of session id. The session ID
259 is returned into pointer provided as argument.

276 file lib/silcutil/silclog.c.
278 * Fixed the channel message payload decryption in the function
279 silc_channel_message_payload_decrypt to not modify the original
280 buffer before it is verified that the message decrypted
281 correctly. Otherwise, next time it is called with correct
282 channel key it won't encrypt since the payload is corrupted.
283 Affected file lib/silccore/silcchannel.c.
285 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

323 silc_client_new_channel_id and silc_idlist_get_channel_by_id
326 * Added cross reference of the joined channels to the
327 SilcClientEntry, and changed the SilcChannelEntry's
328 users list to SilcHashTable. The affected files are
329 lib/silcclient/idlist.[ch].
331 * Fixed a bug in hash table tarversing. While the hash table
332 is traversed with SilcHashTableList the table must not be
333 rehashed. It is now guaranteed that auto rehashable tables
334 are not rehashed while tarversing the list. Also defined that
335 silc_hash_table_rehash must not be called while tarversing
336 the table. Added function silc_hash_table_list_reset that must
337 be called after the tarversing is over. The affected files are
338 lib/silcutil/silchashtable.[ch].
340 * Changed all hash table traversing to call the new
341 silc_hash_table_list_reset in server and in client library.
343 * Added function silc_client_on_channel to return the
344 SilcChannelUser entry if the specified client entry is joined
345 on the specified channel. This is exported to application as
346 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
348 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
350 * Fixed founder regaining problem with JOIN command on normal
351 server. The notify for mode change must be sent always and
352 not only if !cmd->pending. Affected file silcd/command.c.
354 * Fixed the WHOWAS command's reply sending to support the
355 lists correctly. Affected file silcd/command.c.
357 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
359 * When sending JOIN command to router for processing the
360 sender's old command identifier was not saved back to the
361 sender's command context, fixed now. The affected file is
364 * Create the key in JOIN command of the router did not return
365 the channel key, added check for this. Affected file is
368 * Fixed a channel ID update bug in JOIN command reply. Do
369 not directly upgrade the ID but call the function
370 silc_idlist_replace_channel_id if the ID was changed.
371 Affected file silcd/command_reply.c.
373 * Fixed memory leaks from command calling if it would fail.
374 Affected file silcd/command.c.

386 * Removed TRQ from lib/trq, not needed anymore.
388 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
389 with server connections. Later this will be configurable
390 in config file after new config file is done. Affected file
393 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
395 * Fixed a crash in server related to channel announcements.
396 Affected file silcd/server.c.
398 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
400 * Fixed memory leaks in silc_server_create_new_channel*
401 functions. Affected file silcd/server.c.
403 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
404 which ID was changed. This way the router will send the
405 user list for the channel again, and server won't be in
406 desync in some rare circumstances. Affected file is
407 silcd/packet_receive.c.
409 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

438 file silcd/packet_receive.c and silcd/command.c.
440 * Fixed the SERVER_SIGNOFF notify handling on normal server
441 not to save the history information for clients. Same was
442 fixed earlier in remove_clients_by_server function, but not
443 here. Affected file silcd/packet_receive.c.
445 * Raised the default connection-retry count from 4 to 7 in
446 server. Affected file silcd/server.h.
448 * Cancel any possible reconnect timeouts when we start the

461 local entry will always get the unformatted nickname.
462 Affected file lib/silcclient/idlist.c.
464 * Fixed some double frees from client library commands.
465 Affected file is lib/silcclient/command.c.
467 * Fixed CUMODE command in server to assure that no one can

469 little bug. Affected file silcd/command.c.
471 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
473 * Removed the SilcClientCommandDestructor from the client
474 libary, it is not needed anymore. Affected files are
475 lib/silcclient/silcapi.h, command[_reply].[ch],
476 client_notify, idlist.c.
478 * Fixed GETKEY command to first resolve client, and then
479 resolve the server only if the client was not found, instead
480 of resolving both at the same time. Affected file is
481 lib/silcclient/command.c.
483 * Added silc_client_start_key_exchange_cb and lookup the
484 remote hostname and IP address before starting the key
485 exchange with server. The affected file is
486 lib/silcclient/client.c.
488 * The server's public key is now saved using the IP address
489 of the server and not the servername for the filename.
490 The hostname public key filename is checked as an fall back
491 method if the IP address based filename is not found.
493 Fixed the GETKEY command to save the fetched server key
496 Print the remote server's hostname now when new key is
497 received during connection process. Affected file is
498 irssi/src/silc/core/client_ops.c.
500 * Return always our own public key to the client if it asks
501 for it with GETKEY command. Affected file silcd/command.c.
503 * Removed the use_auto_addr variable from default config
504 file since it was in wrong section. Affected file is
507 * Fixed TOPIC_CHANGE notification to not route it when it
508 was sent using silc_server_send_notify_to_channel function.
509 Affected file silcd/command.c.
511 * Fixed silc_server_send_notify_kicked to send the kicker's
512 Client ID also, it was missing. Affected files are
513 silcd/command.c, silcd/packet_send.[ch].
515 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
517 * Do not save client history information in SERVER_SIGNOFF.
518 Fixes the bug in normal server that it does not detect
519 the client becoming valid after the server becomes back
520 online. Affected file silcd/server_util.c.
522 * Added `sock_error' field into the SilcSocketConnection
523 context. When error occurs during socket operation (read
524 or write) the error is saved. Added also new function
525 silc_socket_get_error to return human readable socket error
526 message. Affected files are lib/silcutil/silcsockconn.[ch],
527 lib/silcutil/unix/silcunixsockconn.c, and
528 lib/silcutil/win32/silcwin32sockconn.c.
530 * The server now prints the socket error message in the
531 signoff for client. Affected file silcd/server.c.
533 * Fixed the `created' channel information sending from router
534 to server in JOIN command. Checks now whether the channel
535 really was created or not and set it according that.
537 Fixed the JOIN command to use the client entry's current
538 ID during the joining procedure instead of the one it sent
539 in the command (it is checked though), since it can change
540 between the packet processing and command processing, and
541 would just case unnecessary pain in the client end. Affected
542 file silcd/command.c.
544 * Fixed a channel key payload sending to use correct channel
545 ID when the server was forced to change the channel's ID by
546 router. Router sent the key payload with the old Channel ID.
547 Affected file silcd/packet_receive.c.
549 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
551 * Call silc_server_save_channel_key only if the key payload
552 was provided in the JOIN command's command reply. Affected
553 file silcd/command_reply.c.
555 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
557 * Fixed silc_mp_sizeinbase to return the value correctly with
558 MPI. Affected file lib/silcmath/mp_mpi.c.
560 * Fixed the stop_server signal to correctly stop the scheduler
561 and gracefully stop the server when SIGTERM or SIGINT signals
562 are received. Affected file silcd/silcd.c.
564 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
566 * Simple handling of TERM and HUP signals. Also added some log
567 flushing call around. Affected file is
570 * Fixed small bugs in silclog.c. Now buffering output will take
571 effect after 10 seconds since startup: This will ensure that
572 no important startup messages are lost. Also output redirection
573 will preserve original format ([Date] [Type] message).
574 Affected file is lib/silcutil/silclog.c.
576 * Added two options to the config file, in the logging section:
577 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
578 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
580 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
582 * Do not print the warning about log files not being initialized
583 more than once to avoid excess logging. Affected file is
584 lib/silcutil/silclog.c.
586 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
587 the SIM copying in make install in Makefile.am.pre.
589 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
591 * Rewritten silclog APIs. Globally interesting changes follows:
592 silc_log_set_files() changed to silc_log_set_file().
593 silc_log_set_callbacks() changed to silc_log_set_callback().
594 ROBOdoc documented silclog header file.
595 SilcLogCb now returns bool to wether inihibit the default
596 handler or not (to keep the old behaviour return always TRUE).
597 The new APIs should also fix the problem of the
598 silcd_error.log file that was written in the current directory.
601 Log files streams will remain opened after silc_log_set_file()
602 call, means less CPU usage notably on high traffic servers.
603 File streams are now full buffered, and flushed to the disk
604 every 5 minutes, lesses HD activity and CPU usage.
605 Messages can be redirected, allowing admins to configure
606 one single logfile for all server messages.
607 the silc_log_quick global variable to activate fast-logging.
608 Affected files lib/silcutil/silclog.[ch]
610 * Changed some code to conform new silclog APIs. Affected
611 files are doc/example_silcd.conf.in, silcd/server.c
612 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
615 * Fixed a memory leak that could occur in some situations.
616 Affected file silcd/serverconfig.c.
618 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
620 * Added the silc_client_del_client to remove the client from
621 all channels as well. Affected file lib/silcclient/idlist.c.
623 * Fixed the client library to correctly remove the client
624 from all channels when the client entry is being destroyed.
625 Affected file lib/silcclient/client_notify.c, command.c.
627 * Added auto-nicking support to the client library. If the
628 applicatio now sets client->nickname it will be sent to the
629 server after connecting by the library. This way for example
630 SILCNICK (or IRCNICK) environment variables will have effect
631 and always change the nickname automatically to whatever
632 it is wanted. Affected file lib/silcclient/client.[ch].
634 * Renamed silc_server_command_bad_chars to the
635 silc_server_name_bad_chars and moved it to the
636 silcd/server_util.[ch]. Added also new function
637 silc_server_name_modify_bad to return nickname that
638 includes bad characters as new nickname without those
639 bad characters. This check and modify is now used in
640 silc_server_new_client when the username is initially set
641 as nickname, so it must be checked to be valid nickname.
642 Affected file silcd/packet_receive.c.
644 * The nickname length is now taken from the packet for real
645 and not trusted to strlen() since it clearly can return
646 wrong length for nickname including bad characters. This
647 also applies to channel names. Affected file silcd/command.c.
649 * Removed the lib/silcsilm/modules directory. Modules are now
650 compiled into the lib/silcsim. Fixed the copying of the
651 modules to follow symbolic links in Makefile.am.pre.
653 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
655 * Fixed silc_string_regexify list creation. Fixes bugs with
656 BAN and INVITE commands in server. The affected file is
657 lib/silcutil/unix/silcunixutil.c.
659 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
661 * Removed the command destructor entirely from the server's
662 command and command reply routines. It is not needed, and
663 its usage was buggy and caused crashes. Affected files are
664 silcd/command[_reply].[ch].
666 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
668 * Cancel protocol and NULL sock->protocol if timeout
669 occurred during protocol. Affected file silcd/server.c.
671 * Cancel protocol timeouts always before calling the final
672 callback, to assure that after final callback is called
673 no other state will be called for the protocol anymore.
674 Affected file silcd/protocol.c.
676 * Print error log if incoming connection configuration could
677 not be found. Affected file silcd/server.c.
679 * Fixed JOIN command to correctly save the founder mode
680 to the client on normal SILC server, when the channel
681 was created by the router. Affected file silcd/command.c.
683 * Fixed LIST command (hopefully) to send correct reply
684 packets. Affected file silcd/command.c.
686 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
688 * The silc_packet_receive_process now returns FALSE if the
689 read data was invalid packet, and TRUE if it was ok.
691 The server now checks that if unauthenticated connection
692 sends data and its processing fails the server will close
693 the connection since it could be a malicious flooder.
695 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
697 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
699 * Make sure the warning about error opening a log file is
700 printed only once and not everytime it fails (produces
701 too much useless log). Affected file lib/silcutil/silclog.c.
703 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
705 * Made the silc_server_daemonise() function more readable.
706 Affected file silcd/server.c.
708 * Pid file is now optional, the user may comment it out from
709 the config file. Removed define SILC_SERVER_PID_FILE, we
710 don't need a default any longer. Affected file
711 configure.in.pre, lib/Makefile.am.pre.
713 * Make some use of the pid file. The server now dies at startup
714 if it detects a valid pid file on his path. The server would
715 die anyway in this circumstance, because of the bind() failure.
716 Affected file silcd/silcd.c.
718 * No longer compiling lib/dotconf.
720 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
722 * Fixed JOIN command parsing not to crash. Affected file
723 lib/silcclient/command.c.
725 * Fied the NICK_CHANGE notify to add the new client entry
726 even it is resolved. This removes an <[unknown]> nick
727 thingy bug in the client. Affected file is
728 lib/silcclient/client_notify.c.
730 * Do not try to allocate 0 bytes (efence does not like it)
731 in lib/silccore/silccomand.c when encoding payload.
733 * Do not take IRCNICK as nickname in Irssi SILC client since
734 it is not possible to set nickname before hand connecting
735 the server (TODO has an entry about adding auto-nicking
738 * Changed the silc_server_command_pending to check whether
739 there already exists an pending entry with the specified
740 command, command identifier and pending callback. This is
741 to fix IDENTIFY and WHOIS related crashes that may register
742 multiple pending commands with same identifier. Affected
743 file silcd/command.c.
745 * Fixed the server to reconnect to the router even if it
746 was already reconnecting and EOF was received. This to
747 fix a possibility that the server wouldn't ever try to
748 auto-reconnect to the router. Affected file silcd/server.c.
750 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
752 * Fixed the server's password authentication to use the
753 length of the locally saved password, and not the one
754 sent in the packet. Affected file silcd/protocol.c.
756 * Fixed same password authentication problem in the
757 Authentication Payload handling routines in
758 lib/silccore/silcauth.c.
760 * Yet another password authentication problem fixed with
761 channel password handling in silcd/command.c.
763 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
765 * If first character of string in silc_parse_userfqdn is '@'
766 then do not parse it. Affected file is
767 lib/silcutil/silcutil.c.
769 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
771 * Fixed minor bug in IDENTIFY command reply sending, which
772 caused various weird problems during JOIN when it was
773 resolving names for users. Affected file silcd/command.c.
775 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
777 * Fixed the IDENTIFY command reply sending to chech better valid
778 clients. It was possible to send incomplete list of replies.
779 Affected file silcd/command.c.
781 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
783 * Added silc_client_command[s]_[un]register functions now to
784 dynamically register the commands in client library. Removed
785 the static table of commands. This allows the client library
786 to call commands without causing the application to know about
787 what commands library has called.
789 Removed the INFO command reply kludge to detect when the command
790 was called by library. Now library use its own command reply
791 function for INFO command.
793 Added function silc_client_command_call to call a command.
794 Application can use it to call command, not access the structure
797 Now all commands that are sent by the client library (not
798 explicitly sent by application) use own command reply functions.
800 Affected files around lib/silcclient/ and in
801 irssi/src/silc/core/.
803 * Fixed the WHOIS command reply sending to chech better valid
804 clients. It was possible to send incomplete list of replies.
806 Fixed the WHOIS and IDENTIFY to send the request to router
807 if normal server did not do it and did not find any results.
809 Affected file silcd/command.c.
811 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
813 * Moved the internal data from SilcClient context into its
814 own file, not accesible to application. Affected files
815 lib/silcclient/client.h and lib/silcclient/client_internal.h,
816 and other files in client library.
818 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
820 * Added doc/examples installation target in Makefile.am.pre.
823 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
825 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
826 commands the found client entry will be removed from the
827 cache, after notifying application about the error. Affected
828 file lib/silcclient/command_reply.c.
830 * Changed the /MSG to check for exact nickname user gave, and
831 not let `nick' match `nick@host' if it is only one found. Now,
832 user must type the exact nickname (like nick@host2) even if
833 there are no more than one same nicks found. This is to avoid
834 a possibility of sending nickname to wrong nickname since
835 `nick' could match `nick@host'. Affected file is
836 irssi/src/core/silc-servers.c.
838 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
840 * Do not print "you are now server operator" or similar when
841 giving /away command. Affected files are
842 irssi/src/silc/core/client_ops.c, silc-servers.h.
844 * Made the silc_server_command_pending_error_check to send
845 the same command reply payload it received back to the
846 original sender of the command. This way all arguments
847 that was received by the server will be received by the
848 client too. Affected file silcd/command.c.
850 * Added the silc_idcache_add to return the created cache entry
851 to a pointer. Affected file lib/silccore/silcidcache.[ch].
853 * Add global clients to expire if they are not on any channel.
854 This is because normal server will never know if they signoff
855 if they are not on any channel. The cache expiry will take
856 case of these entries. This is done by normal servers only.
857 The affected files are silcd/command_reply.c,
858 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
860 * If server receives invalid ID notification for WHOIS or
861 IDENTIFY and the ID exists in the lists, it is removed.
862 Affected file silcd/command_reply.c.
864 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
865 in client then client entry that it matches is searched and
866 the nickname is printed on the screen for user. Affected
867 file irssi/src/silc/core/client_ops.c.
869 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
871 * Use cache entry expire time in the LIST command reply to
872 purge old entries from the cache after the LIST command
873 reply has been received. This way we don't have non-existent
874 entries in the cache for too long. Affected file is
875 silcd/command_reply.c.
877 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
879 * If we are normal server, and we've not resolved client info
880 in WHOIS or IDENTIFY from router, and it is global client,
881 we'll check whether it is on some channel. If it is not
882 then we cannot be sure about its validity and will resolve it
883 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
884 file silcd/command.c.
886 * Search channel by name (if possible) rather than by ID
887 in IDENTIFY command's command reply. Affected file is
888 silcd/command_reply.c.
890 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
892 * Distribute to the channel passphrase in CMODE_CHANGE notify.
893 Updated specs and implemented it. Affected file silcd/command.c,
894 silcd/packet_send.c and silcd/packet_receive.c.
896 * Implemented the <founder auth> payload handling in the JOIN
897 command. If provided all conditions for channel joining
898 except requirement to provide correct passphrase can be
899 overrided by the channel founder. Updated the protocol specs.
900 Affected file silcd/command.c.
902 Added support for founder auth in JOIN command in client
903 library. Fixed the parsing of the JOIN command now to support
904 all options as they should be. The affected file is
905 lib/silcclient/command.c.
907 * Optimized the WHOIS and IDENTIFY commands to send the request
908 to router only if it includes nicknames or other names. If
909 they include only IDs then check the local cache first before
910 routing. Affected file is silcd/command.c.
912 * Added channels topic announcements. Affected file is
913 silcd/packet_receive.c and silcd/server.c.
915 * Fixed the silc_server_send_notify_topic_set to really destine
916 the packet to channel. Affected file silcd/packet_send.c.
918 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
919 library. Affected file lib/silcclient/client_notify.c.
921 * Added UMODE announcements. Affected file silcd/server.c.
923 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
925 * Memory leak fixes in:
927 lib/silcutil/silcsockconn.c
928 lib/silcske/silcske.c
931 lib/silccrypt/silcpkcs.c
932 lib/silccore/silccommand.c
933 lib/silccore/silcidcache.c
938 * ROBOdoc documented the lib/silcske/groups.h file and a
939 bit changed the interface for better.
941 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
943 * Update the client entry context in the ID cache after
944 nick change. Affected file lib/silcclient/command.c.
945 Fixes the CUMODE command when regaining founder privileges,
946 and a little WHOIS problem.
948 * Fixed silc_net_gethostbyname to correctly call the
949 inet_ntop. Affected file lib/silcutil/silcnet.c.
951 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
953 * Added IPv6 support checking to the configure.in.pre, added
954 also --enable-ipv6 option to override the check. Affected
955 file configure.in.pre.
957 * The silc_thread_create now calls the start function
958 directly if threads support is not compiled in. Removes
959 ugly #ifdef's from generic code. Affected files are
960 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
962 * Added silc_net_gethostby[name/addr]_async to asynchronously
963 resolve. Affected files are lib/silcutil/silcnet.[ch].
965 * Added support for rendering IPv6 based server, client and
966 channel IDs. Affected file lib/silcutil/silcutil.c.
968 * Added support for creating IPv6 based server IDs. Affected
969 file is silcd/serverid.c.
971 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
973 * Added silc_net_gethostby[addr/name] into the
974 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
975 routines. Added silc_net_is_ip[4/6]. Affected file is
976 lib/silcutil/unix/silcunixnet.c. All routines that take
977 address as argument now supports both IPv4 and IPv6 addresses.
979 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
981 * Fixed LIST command reply sending in server. Affected file
984 * Server now sends the kicker's client ID in the KICK notify
985 to the kicked client. Affected file silcd/command.c.
987 * The client library now parses the kickers client ID and
988 UI displays it. Affected files lib/silcclient/client_notify.c
989 and irssi/src/silc/core/silc-channels.c, module-formats.c.
991 * Made all payload parsing function prototypes consistent.
992 They all take now const unsigned char * and uint32 pair as
993 the payload data instead of SilcBuffer. Changes all around
994 the source tree. Other unsigned char* -> const unsigned char*
995 changes around the tree as well.
997 * Optimized SFTP client and server packet sending not to
998 allocate new buffer for each packet but to recycle the
999 first allocated buffer. Affected files are
1000 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1002 * Optimized the SFTP client to use SilcList instead of
1003 SilcDList for requests, because it is faster. Affected file
1004 is lib/silcsftp/sftp_client.c.
1006 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1007 into lib/silccore/silcid.[ch].
1009 Renamed silcpayload.[ch] into silcargument.[ch].
1011 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1013 * If client entry is deleted with active key agreement
1014 session, abort the session.
1016 The silc_client_abort_key_agreement now calls the completion
1017 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1019 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1022 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1024 * Don't use __restrict in older GCC's. Affected file is
1025 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1027 * silc_net_localhost now attempts to reverse lookup the
1028 IP/hostname. Affected file lib/silcutil/silcnet.c.
1030 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1031 command. It can be used to gain founder privileges at
1032 the same time when joining the channel.
1034 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1035 kicker's client ID as well. Updated protocol specs.
1037 Defined that the server must send SILC_COMMAND_IDENTIFY
1038 command reply with error status to client who sent
1039 private message with invalid client ID.
1041 Updated the protocol specification.
1043 * Added silc_server_send_command_reply to send any
1044 command reply. Affected file silcd/packet_send.[ch].
1046 * Added silc_id_payload_encode_data to encode ID payload
1047 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1049 * The server now send IDENTIFY command reply with error
1050 status if client ID in private message is invalid. Affected
1051 file silcd/packet_receive.c.
1053 * Save the server key file with server's IP address in
1054 the filename instead of hostname. The affected file is
1055 irssi/src/silc/core/client_ops.c.
1057 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1059 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1062 * Added libtool support for compiling shared objects in
1063 lib/silcsim. Affected file configure.in.pre and
1064 lib/silcsim/Makefile.am. Original patch by cras.
1066 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1068 * Pid file configuration, and server's config file fixes
1069 patch by toma. Updated CREDITS file.
1071 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1073 * Fixed silc_client_channel_message to not try to decrypt
1074 the message twice if it resolved the destination client
1075 information. This could cause of dropping one channel
1076 message. Affected file lib/silcclient/client_channel.c.
1078 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1080 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1081 lib/silcclient/client.c. This function is used when the SILC
1082 Client is run under some other scheduler, or event loop or
1083 main loop. On GUI applications, for example this may be
1084 desired to used to run the client under the GUI application's
1085 main loop. Typically the GUI application would register an
1086 idle task that calls this function multiple times in a second
1087 to quickly process the SILC specific data.
1089 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1091 * Fixed silc_server_drop() for dropping the supplementary
1092 groups as well, this could cause a security hole on some
1095 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1097 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1100 * Write PID file after dropping privileges. Added -F option
1101 to run server on foreground. A patch by debolaz.
1102 Affected files silcd/server.c, silcd/silcd.c.
1104 * Fixed MOTD to return the MOTD file server name. Affected
1105 file silcd/command.c.
1107 * Added INFO command reply handling to the Irssi SILC Client.
1108 Affected file irssi/src/silc/core/client_ops.c.
1110 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1112 * Fixed the silc_idcache_list_* routines to really support
1113 the dynamic list. Fixes a crash. Affected file is
1114 lib/silccore/silcidcache.c.
1116 * Fixed the LIST command reply to really call LIST command's
1117 pending callbacks. Affected file silcd/command_reply.c.
1119 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1121 * Update conn->local_entry->nickname after giving NICK
1122 command. Affected file lib/silcclient/command.c.
1124 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1126 * Added the [pid] option to the silcd configuration file
1128 Affected files: serverconfig.[ch] and silcd.c
1130 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1132 * Save fingerprint in WHOIS command reply in server.
1133 Affected file silcd/command_reply.c.
1135 * Fixed NICK commands pending callback registration.
1136 Affected file lib/silcclient/command.c.
1138 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1140 * Use ++server->cmd_ident when sending commands in server,
1141 instead of random number. Affected file silcd/command.c.
1143 * Fixed GETKEY command reply to call actually GETKEY pending
1144 command callbacks. Affected file silcd/command_reply.c.
1146 * A bit stricter check for nicknames. Check for same nickname
1147 in NICK command also. Affected file silcd/command.c.
1149 * Do not call INFO command everytime client ID changes, only
1150 during first connecting. Affected file lib/silcclient/client.c.
1152 * Set the new nickname only after successful command reply for
1153 NICK command is returned by server. Affected file
1154 lib/silcclient/command.c.
1156 * Remove nicknames from nicklist during server_signoff notify.
1157 Should fix /NAMES bit more. The affected file is
1158 irssi/src/silc/core/silc-channels.c.
1160 * Added `fingerprint' field to the SilcIDListData in the
1161 silcd/idlist.h to hold the fingerprint of the client's
1164 Send the fingerprint of the client's public key in WHOIS
1167 Affected files silcd/command.c, and silcd/idlist.[ch].
1169 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1170 create fingerprint from given data.
1172 * Show the fingerprint of the client's public key in WHOIS.
1173 Affected files irssi/src/module-formats.[ch] and
1174 irssi/src/silc/core/client_ops.c.
1176 * Format the multiple same nicknames also during JOIN and
1177 NICK_CHANGE notifys. Affected file is
1178 lib/silcclient/client_notify.c.
1180 * Do not print error on screen for invalid private message
1181 payload since it can come if someone is sending private
1182 messages with wrong key. Affected file
1183 lib/silccore/silcprivate.c.
1185 * Fixed multiple concurrent /PING crash. Affected file
1186 lib/silcclient/command.c.
1188 * Changed the wrong ID encoding. All IP addresses must be
1189 in MSB first order in encoded format. They were encoded
1190 wrong and was in LSB format. Affected files are
1191 silcd/serverid.c, lib/silcutil/silcutil.c.
1193 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1195 * Call the `connect' client operation through the scheduler
1196 in case of error. Affected file lib/silcclient/client.c.
1198 * Call the `failure' client operation even if the error
1199 occurred locally during a protocol. Affected file is
1200 lib/silcclient/protocol.c.
1202 * Added support of sending LIST command to router from normal
1203 server. This way normal server can get list of all channels
1204 in the network too. Fixed the channel list sending in the
1205 server too. Affected files are silcd/command.c, and
1206 silcd/command_reply.[ch].
1208 * Added silc_server_update_channels_by_server and
1209 silc_server_remove_channels_by_server. They are used during
1210 disconnection of primary router and in backup router protocol.
1211 Affected file silcd/server_util.[ch], silcd/server.c and
1212 silcd/server_backup.c.
1214 * Fixed channel adding to global list in IDENTIFY command
1215 reply in server. Affected file silcd/command_reply.c.
1217 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1219 * If the incoming packet type is REKEY or REKEY_DONE process
1220 that packet always synchronously. Fixes yet another MAC
1221 failed error on slow (dialup) connections. Affected file
1222 lib/silcclient/client.c and silcd/server.c.
1224 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1226 * Call check_version SKE callback for initiator too. Affected
1227 file lib/silcske/silcske.c.
1229 * Implemented fix for security hole found in the SKE that was
1230 fixed in the specification few days back; the initiator's
1231 public key is now added to the HASH value computation.
1232 Added backwards support for the old way of doing it too, for
1233 old clients and old servers. Affected file is
1234 lib/silcske/silcske.c.
1236 * Enabled mutual authentication by default in SKE. If initiator
1237 is not providing mutual authentication the responder will
1238 force it. This will provide the proof of posession of the
1239 private key for responder. The affected files are
1240 lib/silcclient/protocol.c and silcd/protocol.c.
1242 * Do not cache anymore the server's public key during SKE.
1243 We do mutual authentication so the proof of posession of
1244 private key is done, and if the server is authenticated in
1245 conn auth protocol with public key we must have the public
1246 key already. Affected file silcd/protocol.c.
1248 * Added new global debug variable: silc_debug_hexdump. If
1249 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1250 file lib/silcutil/silclog.[ch].
1252 * Fixed compilation warning due to char * -> const char *.
1253 Affected files lib/silcutil/silcnet.h, and
1254 lib/silccore/silcauth.[ch].
1256 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1258 * Fixed CMODE command when new channel key was created. If
1259 the creation failed the old key was removed. Next time giving
1260 same command would crash the server since the old key was
1261 freed already. Affected file silcd/command.c.
1263 * Fixed the silc_server_announce_get_channels to not crash
1264 on reconnect. Affected file silcd/server.c.
1266 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1268 * Added silc_log_set_debug_string function to set a regex
1269 string to match for debug output. Only the function names,
1270 or filenames matching the given debug string is actually
1271 printed. This way it is possible to filter out those debug
1272 strings that user is not interested in.
1274 Fixed a bug in silc_string_regexify.
1276 Affected files lib/silcutil/silclog.[ch], and
1277 lib/silcutil/unix/silcunixutil.c.
1279 * Changed the -d options in both server and Irssi SILC client
1280 to take the debug string as argument. Affected files
1281 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1283 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1285 * Added silc_hash_babbleprint to create a Bubble Babble
1286 Encoded fingerprint. The encoding is developed by Antti
1287 Huima (draft-huima-babble-01.txt), and it creates human
1288 readable strings out of binary data. Affected file
1289 lib/silccrypt/silchash.[ch].
1291 * Print the babble print now in addition of fingerprint as well
1292 in Irssi SILC client. Affected files are
1293 irssi/src/fe-common/silc/module-formats.[ch],
1294 irssi/src/fe-common/silc/core/client_ops.c.
1296 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1298 * Fixed a security problem found in SKE. The initiator's
1299 public key too is now added to the HASH hash value creation
1300 which is signed by the responder to create the SIGN value.
1301 This will prevent anyone in the middle to lie to the responder
1302 about the initiator's public key. If this is done now, the
1303 man in the middle will get caught. Updated the protocol
1306 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1308 * Better installation directory handling. Configure module
1309 paths and other paths automatically to example_silc* files
1310 in doc/. A patch by toma.
1312 * Fixed compiler warning from MPI library, and from SILC RNG.
1315 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1316 It can be configured with ./configure. A patch by toma.
1318 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1320 * Find correct make to use in prepare-clean. A patch by
1321 toma. Affected file prepare-clean.
1323 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1325 * Added irssi variables use_auto_addr, auto_bind_ip,
1326 auto_bind_port and auto_public_ip.
1328 * Changed the interface for silc_client_send_key_agreement
1329 in lib/silcclient/silcapi.h
1333 irssi/src/silc/core/silc-core.c
1335 lib/silcclient/silcapi.h
1336 irssi/src/silc/core/silc-channels.c
1337 lib/silcclient/client_keyagr.c
1340 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1342 * Added silc_pkcs_public_key_compare to compare two
1343 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1345 * Check that the client who set the founder mode on the
1346 channel is the same client that is giving the founder
1347 mode to itself. It is done by comparing the saved public
1348 key (it is saved even in the authentication is passphrase).
1349 Affected file silcd/command.c.
1351 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1353 * Do not process packet for disconnected socket connection.
1354 Affected file lib/silccore/silcpacket.c.
1356 * Process the DISCONNECT packet through scheduler in the
1357 client library. Affected file lib/silcclient/client.c.
1359 * Fixed the silc_client_packet_parse to not to increase
1360 the packet sequence number if the conn->sock and the
1361 current socket connection is not same. This can happen
1362 for example during key agreement when the conn includes
1363 multiple socket connections (listeners). Affected file
1364 lib/silcclient/client.c.
1366 * The sender of the file transfer request now provides also
1367 the pointer (listener) for the key exchange protocol. If
1368 the listener cannot be created then it sends empty key
1369 agreement and lets the receiver provide the listener.
1371 Added `local_ip' and `local_port' arguments to the
1372 silc_client_file_send. If they are provided they are used,
1373 if not then it will attempt to find local IP address, if
1374 not found or bind fails then the remote client will provide
1377 Affected files are lib/silcclient/client_ftp.c and
1378 lib/silcclient/silcapi.h.
1380 * Extended the FILE SEND command to support defining the
1381 local IP and port for key exchange listener. They are
1382 optional. Affected file irssi/src/silc/core/silc-servers.c.
1384 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1386 * Defined to WHOIS command reply the sending of fingerprint
1387 of the client's public key (if the proof of posession of the
1388 corresponding private key is verified by the server).
1389 Updated to the protocol specification.
1391 * Added support of receiving the client's public key's
1392 fingerprint in command reply in client library. Affected
1393 file is lib/silcclient/command_reply.c, and
1394 lib/silcclient/idlist.[ch].
1396 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1398 * Do not send over 128 chars long nickname to the server
1399 in NICK command. Affected file lib/silcclient/command.c.
1401 * Do not send over 256 chars long channel names to the server
1402 in JOIN command. Affected file lib/silcclient/command.c.
1404 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1406 * Assure that silc_server_close_connection cannot be called
1407 twice for same socket context. Affected file is
1410 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1412 * Send error message to application if opening file for
1413 writing during file transfer fails. Affected file is
1414 lib/silcclient/client_ftp.c.
1416 Remove all file transfer sessions for a client that we're
1417 removing from ID cache.
1419 Affected file is lib/silcclient/client_ftp.c.
1421 * Fixed silc_net_addr2bin to return correct address. Affected
1422 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1424 * Fixed file transfer session removing on signoff notify.
1425 Affected file irssi/src/silc/core/silc-servers.c.
1427 * Added the SilcClientFileError to be returned in the monitor
1428 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1429 Affected file lib/silcclient/silcapi.h.
1431 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1433 * Fixed a crash in silc_client_ftp_free_sessions and
1434 silc_client_ftp_session_free_client. Affected file
1435 lib/silcclient/client_ftp.c.
1437 * Added `disabled' field in the SilcChannelEntry in the server
1438 to indicate if the server entry is disabled. Affected file
1439 silcd/idlist.h, silcd/command[_reply].c.

1448 * Fixed a crash in client resolving in client_prvmsg.c in
1449 client library. Affected file lib/silcclient/client_prvmsg.c.
1451 * Do not actually remove the client directly from ID cache
1452 during SERVER_SIGNOFF, but invalidate it. This way we
1453 preserve the WHOWAS info for the client. Affected file
1454 silcd/server_util.c.
1456 * Fixed SERVER_SIGNOFF notify handling in the server. The
1457 server is now able to process incoming SERVER_SIGNOFF notify
1458 for a server that it doesn't even know about. It will remove
1459 the clients provided in the notify. Affected file
1460 silcd/packet_receive.c.
1462 * Check for partial packet in data queue after every packet that
1463 was found from the queue. Return and wait for more data if
1464 there is partial data in queue. Affected file is
1465 lib/silccore/silcpacket.c.
1467 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1469 * Added SilcClietFileError enum to indicate error in
1470 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1471 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1472 Affected files lib/silcclient/silcapi.h and
1473 lib/silcclient/client_ftp.c.
1475 * Check that newsize in silc_buffer_realloc is larger than
1476 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1478 * Added better monitor of file transfers. It now monitors
1479 key agreement protocol during the file transfer too. Added
1480 error reporting too. Affected files
1481 irssi/src/silc/core/silc-servers.c,
1482 irssi/src/fe-common/silc/module-formats.[ch].
1484 * Wrote a help file for FILE command.
1486 * Added silc_rng_global_get_byte_fast to get not-so-secure
1487 random data as fast as possible. Random data is read from
1488 /dev/urandom if available and from the SILC RNG if not
1489 available. It is used in padding generation. Affected file
1490 lib/silccrypt/silcrng.[ch].
1492 * All packets in client library are now processed synchronously.
1493 Optimized packet processing a lot. Affected file
1494 lib/silcclient/client.c.
1496 * All server connection packets are processing synchronously
1497 now in server, to optimize packet processing. Affected file
1500 * Include files are installed now only in Toolkit distribution
1501 if make install is given. Affected files: all Makefile.am's.
1503 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1505 * Assure that silc_client_notify_by_server_resolve does not
1506 resolve the client information multiple times. If it cannot
1507 be found by the first it cannot be found at all. Affected
1508 file lib/silcclient/client_notify.c.
1510 * Fixed WHOWAS command reply calling. Affected file
1511 lib/silcclient/command_reply.c.
1513 * Removed all references to silc_idlist_get_client from the
1514 Irssi SILC client since that call is internal call used by
1515 the library. The Irssi SILC client will use now client
1516 retrieval functions found in silcapi.h.
1518 * Fixed a bug in resolving nickname info before sending
1519 private message. It used freed memory. Affected file
1520 irssi/src/silc/core/silc-servers.c.
1522 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1524 * Assure my_channels statistics cannot go negative in server.
1525 Affected files silcd/server.c, silcd/server_util.c.
1527 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1537 lib/sftp/sftp_fs_memory.c.
1539 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1541 * Added silc_net_localip to return local host's IP address.
1542 Affected file lib/silcutil/silcnet.[ch].
1544 * If key exchange or rekey protocol is active for a connection
1545 parse all packets syncronously since there might be packets
1546 in packet queue that we are not able to process without first
1547 processing packets before them. Affected file silcd/server,
1548 lib/silcclient/client.c.
1550 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1551 whether library should continue processing the packet.
1552 Affected file lib/silccore/silcpacket.h.
1554 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1555 SilcSFTPMonitorData to SFTP server to monitor various

1580 * Renamed silc_file_read and silc_file_write to functions
1581 silc_file_readfile and silc_file_writefile. Added function
1582 silc_file_open and silc_file_close. Affected files
1583 lib/silcutil/silcutil.[ch].
1585 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1587 * Resolve the client info when received private message or
1588 channel message for a client which nickname we don't know.
1589 Affected files lib/silcclient/client_prvmsg.c and

1598 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1599 is incomplete and is being resolved, it won't be resolved
1602 Make sure also that USERS command reply does not resolve
1603 twice information. Affected file is
1604 lib/silcclient/command_reply.c.
1606 Make sure that silc_client_get_clients_by_list does not
1607 resolve twice same information.
1609 * Check for valid client->id in the silc_server_free_client_data.
1610 Affected file silcd/server.c.
1612 * Fixed /GETKEY nick@server not to crash if the server entry
1613 is not found. Affected file lib/silcclient/command.c.
1615 * Fixed the silc_server_check_cmode_rights to check the
1616 requested modes correctly. Affected file silcd/command.c.
1618 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1620 * Better checks for non-printable chars in nick added.
1621 Affected file silcd/command.c.
1623 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1625 * Call the silc_server_udpate_servers_by_server in the
1626 primary router that comes back online in the backup resuming
1627 protocol. Otherwise it routes packets wrong. Affected file
1628 silcd/server_util.[ch], silcd/server_backup.c.
1630 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1632 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1633 lib/silcutil/silcbuffmt.[ch].
1635 * Redefined the SILC packet header to include the padding
1636 length. Affected file lib/silccore/silcpacket.[ch].
1638 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1639 length for maximum padding up to 128 bytes). Affected
1640 file lib/silccore/silcpacket.h.
1642 * Removed all backwards support for old 0.5.x MAC thingies.
1643 The SILC packet header change makes it impossible to be
1644 backwards compatible.
1646 * Send the ENDING packet with timeout in the backup resuming
1647 protocol. This is to assure that all routers has connected
1648 to the primary router. Affected file silcd/server_backup.c.
1650 * Changed the RNG to take the first IV from random data. It
1651 used to take it from zero actually. Changed the RNG also
1652 to use /dev/urandom during session. /dev/random is used
1653 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1655 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1657 * Changed the SILC packet header to have the first two bytes
1658 (the packet length) encrypted. Affected files aroung the
1659 code tree, lib/silccore/silcpacket.[ch]. Removed the
1660 SilcPacketCheckDecrypt callback. It is not needed anymore
1661 since the silc_packet_receive_process will determine now
1662 whether the packet is normal or special.
1664 * Implemented the unidirectional MAC keys. Affected files
1665 lib/silcske/silcske.c, silcd/protocol.c and
1666 lib/silcclient/protocol.c.
1668 * Implemented the packet sequence number to the MAC computation.
1669 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1670 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1671 lib/silcclient/protocol.c.
1673 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1675 * Allow backup router to announce servers. All servers
1676 announced by backup router are added to the global list
1677 automatically. Update hte server's socket to our primary
1678 router also when backup router announces a server.
1679 Affected file silcd/packet_receive.c.
1681 * Do not update the client->router in the function
1682 silc_server_udpate_clients_by_server if the client is on
1683 global list. We might fail to find any specific server
1684 for locally connected clients and local cell clients. They
1685 should still use the `from' and not `to' as client->router.
1686 This fixes backup router resuming protocol. Affected file
1687 silcd/server_util.c.
1689 * Decrease channel statistics count only if the channel
1690 deletion worked. Affected files are silcd/server.c and
1691 silcd/server_util.c.
1693 * Added silc_server_update_servers_by_server to update origin
1694 of all server entries. Used during backup router protocol.
1695 Affected files silcd/server_util.[ch], silcd/server.c. and
1696 silcd/backup_router.c.
1698 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1699 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1700 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1701 lib/silccrypt/silchmac.c.
1703 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1705 * Assure that router cannot reroute the same channel message
1706 to the sender. Affected file silcd/packet_receive.c.
1708 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1710 * Made better checks that the channel message is not sent
1711 to the router it came from. Affected file is
1712 silcd/packet_send.c. Fixed memory leak too.
1714 * Announce informations for incoming router connection, but
1715 only after checking if it is replaced by backup router.
1716 Affected file silcd/packet_receive.c.
1718 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1720 * Fixed the backup resuming protocol to work in multiple
1721 router environment. Affected file silcd/server_backup.c.
1723 * Route packet only to one router in the function
1724 silc_server_packet_send_to_channel. Affected file is
1725 silcd/packet_send.c.
1727 * Fixed silc_server_send_notify_dest to set the broadcast
1728 flag. Fixed the silc_server_send_notify_topic to actually
1729 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1730 Affected file silcd/packet_send.c.
1732 * Changed the SFTP Filesystem interface. Changed the
1733 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1734 the filesystem operation function. The SilcSFTPFilesystem
1735 is now a context that is allocated by all filesystem allocation
1736 functions and it already includes the operations structure
1737 and filesystem specific context. It is given as argument
1738 now to the silc_sftp_server_start. This made the interface
1739 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1740 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1742 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1744 * Changed the backup router adding and getting interfaces
1745 in the server. The router that will be replaced by the
1746 specified backup router is now sent as argument. Affected
1747 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1750 * Added silc_net_addr2bin_ne to return the binary form of
1751 the IP address in network byte order. Affected files
1752 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1754 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1756 * Check for existing server ID in silc_server_new_server
1757 and in silc_server_connect_to_router_final and remove the
1758 old entry if it exists. Affected file silcd/packet_receive.c,
1761 * Send the channel message always to only one router, either
1762 in upstream or downstream. Affected file is
1763 silcd/packet_send.c.
1765 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1767 * Wrote the definition of the backup resuming protocol to the
1768 protocol specification.
1770 * Removed one redundant channel key generation from normal
1771 server during joining procedure. Removed one redundant
1772 channel key sending from server to router during joining
1773 procedure. Affected file silcd/command.c.
1775 * Made minor bugfixes to the backup router resuming protocol.
1776 Affected file silcd/server_backup.c, server.c.
1778 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1780 * Added --disable-asm configuration option. Affected files
1781 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1784 * Implemented the backup resuming protocol that is used to
1785 resume the primary router position in the cell after the
1786 primary router comes back online. Affected files
1787 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1788 and silcd/server_util.[ch].
1790 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1792 * Sleep two (2) seconds after sending QUIT command to server.
1793 Affected file lib/silcclient/command.c.
1795 * Assure that if outgoing data buffer is pending do not force
1796 send any data. Affected file silcd/packet_send.c.
1798 * Assure that if outgoing data buffer is pending do not force
1799 send any data. Affected file lib/silcclient/client.c.
1801 * Implemented the backup router support when the primary router
1802 goes down. The servers and routers can now use the backup
1803 router as new primary router without loosing connectivity.
1805 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1807 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1808 in the server to indicate disabled entry. All data read
1809 from the connection will be ignored and no data is sent
1810 for entry that is disabled. Affected files are
1811 silcd/idlist.h, silcd/server.c.
1813 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1815 * Created SFTP client and server test programs in the
1816 lib/silcsftp/tests directory.
1818 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1820 * Implemented memory filesystem (virtual filesystem) for
1821 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1824 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1826 * Implemented the SFTP (SSH File Transfer Protocol) to the
1827 lib/silcsftp. It includes SFTP client and SFTP server
1830 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1832 * Moved lib/silccore/silcprotocol.[ch] to the
1833 lib/silcutil library.
1835 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1836 take variable argument list pointer as argument. Affected
1837 file lib/silcutil/silcbuffmt.[ch].
1839 * Added silc_buffer_set function that is used to set data
1840 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1841 Affected file lib/silcutil/silcbuffer.h.
1843 * Changed various routines in the core library to use the new
1844 silc_buffer_set instead of allocating new buffer only for
1847 * Added 64-bit value formatting and unformatting support to the
1848 silc_buffer_[un]format routines. Affected file is
1849 lib/silcutil/silcbuffmt.[ch].
1851 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1852 to includes/bitmove.h.
1854 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1856 * Fixed channel user mode saving in client library. Affected
1857 file lib/silcclient/command[_reply].c.
1859 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1861 * Defined the file transfer to the SILC Protocol. Added
1862 new packet type SILC_PACKET_FTP and defined File Transfer
1863 Payload. The mandatory file transfer protocol is SFTP
1864 (SSH File Transfer Protocol). Affected file in addition
1865 of the internet draft is lib/silccore/silcpacket.h.
1867 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1868 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1869 is used as part of backup router protocol when the primary
1870 router of the cell is back online and wishes to resume
1871 the position as primary router.
1873 * Redefined the MAC generation keys in the protocol. The
1874 same key is not used anymore in both direction. Both
1875 direction will now use different keys for sending and
1876 receiving. This fixes a potential security flaw. This
1877 change causes incompatibilities in the protocol.
1879 * Redefined also the MAC computation from the packet.
1880 An packet sequence number is now added to the MAC
1881 computation. This prevents possible replay attacks against
1882 the protocol. This change too causes incompatibilities
1885 Added `sequence' field to the SilcPacketContext to hold
1886 the current sequence number for the packet.
1888 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1890 * Added `created' field to the SilcIDListData in the file
1891 silcd/idlist.h to indicate the time when the entry was
1894 * Added `created' field to the SilcChannelEntry too. Affected
1895 file silcd/idlist.h.
1897 * Added `creation_time' aguments to all the announcement functions
1898 in the server. If it is provided then only the entries that
1899 was created after the provided time frame are actually
1900 announced. Affected file silcd/server.[ch].
1902 * The protocol says that the Channel ID's IP address must be
1903 based on the router's IP address. Added check for this in
1904 the silc_server_new_channel when processing incoming New Channel
1905 Payload. Affected file silcd/packet_receive.c.
1907 * Print out the correct version with --version in SILC client.
1908 Affected file irssi/src/silc/core/silc-core.c.
1910 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1912 * Fixed WHOWAS command to check for completnes of the client
1913 entry always, not just when the command is coming from client.
1914 Affected file silcd/command.c.
1916 * Added new function silc_server_packet_queue_purge to purge the
1917 outgoing data queue to the network. After the function returns
1918 it is guaranteed that the outgoing packet queue is empty.
1919 Affected file silcd/packet_send.[ch].
1921 * Purge the outgoing packet queue in the rekey protocol's final
1922 callback to assure that all rekey packets go to the network
1923 before quitting the protocol. Affected file silcd/server.c.
1925 * Added silc_client_packet_queue_parse as similar function as
1926 in server to the client library. The affected file is
1927 lib/silcclient/client.c.
1929 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1931 * Splitted silcd/server.c and created silcd/server_util.[ch]
1932 for utility functions.
1934 * Added new socket flag SILC_SF_DISABLED to indicate that the
1935 connection is open but nothing can be sent to or received from
1936 the connection. Affected file lib/silcutil/silsockconn.[ch].
1937 The checking for disabled socket is checked in the low level
1938 silc_socket_write and silc_socket_read functions.
1940 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1942 * Allow only nicknames and channel names that fits into the
1943 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1945 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1947 * When processing JOIN command reply in server check that if
1948 the channel exists in our global list we'll move it the local
1949 list. Affected file silcd/command_reply.c.
1951 * Fixed the check whether client is joined on the channel already
1952 in JOIN command. Affected file lib/silcclient/command.c.
1954 * Fixed the JOIN command reply to check whether the channel
1955 already exists. Affected file lib/silcclient/command_reply.c.
1957 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1959 * Added silc_ske_status_string to map the SKE error numbers
1960 to readable strings. The affected files are
1961 lib/silcske/silcske[_status].[ch].
1963 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1965 * Do not show the private channels on the WHOIS channel list
1966 as it is not allowed by the protocol. The affected file is
1969 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1971 * Assure that the packet length digged from the actual packet
1972 is something sensible in the silc_packet_decrypt_rest_special
1973 in lib/silccrypt/silcpacket.c.
1975 * Free and NULL the allocated pointer in silc_hmac_alloc if
1976 the HMAC allocation fails. The affected file is
1977 lib/silccrypt/silchmac.c.
1979 * Print the selected security properties to the log files in
1980 the server. Affected file silcd/protocol.c.
1982 * Add SKE's reference counter even if calling the completion
1983 callback manually. Otherwise it goes negative, although it
1984 does not cause any problems. The affected file is
1985 lib/silcske/silcske.c.
1987 * Remove the client entry with short timeout after giving the
1988 KILL command. Affected file lib/silcclient/command.c.
1990 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1991 case all found clients are already disconnected (WHOWAS would
1992 found them) in the server. Affected file silcd/command.c.
1994 * Update the last_receive (time of last data received) to be
1995 updated only when received private or channel message so that
1996 the idle time showed in WHOIS makes more sense.
1998 * Added boolean field `valid' in to the SilcClientEntry in the
1999 client library to indicate whether the entry is valid or not.
2000 This fixes the nickname change bug on channel when changing
2001 the nickname to be same than the old (like nick to Nick) the
2002 nickname formatter doesn't set the new nick anymore to Nick@host.
2003 Affected file lib/silcclient/idlist.[ch].
2005 * Now actually fixed the nickname changing on disconnection.
2006 Added new function silc_change_nick to the Irssi SILC Client.
2007 Affected file irssi/src/silc/core/client_ops.c,
2008 irssi/src/silc/core/silc-nicklist.[ch].
2010 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2012 * Check that the public key exists in the GETKEY command before
2013 trying to encode it. Affected file silcd/command.c.
2015 * Print some notifications on received public keys with GETKEY
2016 command in the Irssi SILC Client. Affected files are
2017 irssi/src/fe-common/silc/module-formats.[ch],
2018 irssi/src/silc/core/client_ops.c.
2020 * Use IDENTIFY command to resolve the server information in the
2021 GETKEY command instead of INFO command. Affected file
2022 lib/silcclient/command.c.
2024 * All command reply functions in the client library now calls
2025 the pending command reply callbacks even if an error has
2026 occurred. The server has done this a long time and now it was
2027 time to move the client library to this as well. Now all
2028 errors can be delivered back to the pending command reply
2029 callbacks if necessary. Affected files are
2030 lib/silcclient/command[_reply].[ch].
2032 * Change the nickname on disconnection back to the username
2033 because in reconnect the server will enforce it to it anyway.
2034 Affected file irssi/src/silc/core/silc-servers.c.
2036 * Fixed a config file parsing bug in the Irssi SILC client.
2037 Affected file irssi/src/silc/core/clientconfig.c.
2039 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2041 * When printing the channel mode on JOIN, verify that the
2042 channel key and channel's HMAC are valid. Affected file
2043 irssi/src/silc/core/client_ops.c.
2045 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2047 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2048 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2049 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2051 * Removed channel key rekey task deleting from the function
2052 silc_server_save_channel_key. Affected file silcd/server.c.
2053 Added explicit timeout task context instead that is used to
2054 delete the task if we are registering a new task before the
2055 new task has elapsed.
2057 * When channel key rekey occurs the client library now saves
2058 the old channel key for a short period of time (10 seconds) and
2059 is able to use it in case some is still sending channel
2060 messages encrypted with the old key after the rekey. Affected
2061 file lib/silcclient/[idlist.h|client_channel.c].
2063 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2065 * Added check to the silc_server_new_id_real to not accept
2066 new ID if it is the sender's own ID. Affected file is
2067 silcd/packet_receive.c.
2069 * Assure that we do not announce ourself or the one we've
2070 sending our announcements when we're router and are announcing
2071 servers to our primary router. Affected file silcd/server.c.
2073 * Fixed silc_server_command_identify_check_client to assemble
2074 correct WHOIS packet. It send corrupted WHOIS packet and
2075 caused problem with router to router connections. Affected
2076 file silcd/command.c.
2078 Fixed also silc_server_command_whois_check the same way
2079 as for the IDENTIFY command.
2081 * Added new SilcIDListStatus to the server in the SilcIDListData
2082 structure. The status now includes the current status of
2083 the entry (like registered, resolved etc.). Affected file
2084 silcd/idlist.[ch]. Defined a bunch of different status types
2085 as well. This replaced the old boolean registered field as well.
2087 Added resolve_cmd_ident field to the SilcClientEntry structure
2088 too so that if the entry is for example being resolved so
2089 another command may attach to the same pending command reply
2090 without requiring to resolve the same entry again. This concept
2091 should optimize the WHOIS and the IDENTIFY resolving under
2092 heavy load by taking away unnecessary resolving for entries
2093 that are being resolved already.
2095 Added support for adding multiple pending commands for one
2096 command idenfier. Affected file silcd/command[_reply].[ch].
2098 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2099 before deleting the data. Otherwise the hash table will have
2100 freed data in comparison functions. Affected file is
2101 silcd/command_reply.c.
2103 * Fixed silc_idlist_replace_client_id to add the new entry to
2104 the cache with NULL nickname. Otherwise there will be invalid
2105 memory as the nickname after the nickname is freed. Affected
2106 file silcd/packet_receive.c.
2108 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2109 saved into wrong slots because the previous number of entries
2110 was not taken into account. Affected file silcd/idlist.c.
2111 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2113 * If we are router and we receive JOIN notify to a channel that
2114 does not have any users then notified client is marked as the
2115 channel founder, as it is it. The affected file is
2116 silcd/packet_receive.c
2118 * Added to the extended hash table API's table_del_*ext functions
2119 the destructor as argument too, so that the caller can decide
2120 which destructor to use or whether to use destructor at all.
2121 Affected file lib/silcutil/silchashtable.[ch].
2123 * Fixed ID Cache purging. It actually deleted the entries from
2124 the hash table after the data was freed. The hash table ended
2125 up comparing freed memory. The affected file is
2126 lib/silccore/silcidcache.c.
2128 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2130 * Fixed Irssi SILC client's KILL command's HELP syntax.
2132 * The USERS command now resolves the detailed user information
2133 if the userinfo field is missing. Affected file is
2134 lib/silcclient/command_reply.c.
2136 * Do not print error in silc_file_read if the read file does
2137 not exist. Just silently return NULL. Affected file is
2138 lib/silcutil/silcutil.c.
2140 * Fixed the silc_log_output to not wine about NULL filename
2141 and to not create some bogus " " filename. Affected file is
2142 lib/silcutil/silclog.c.
2144 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2146 * Fixed various printing bugs on the user interface in the
2147 Irssi SILC Client. Minor changes that were forgotten from
2150 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2152 * Fixed the configure.in.pre and the compilation and distribution
2153 environment to support the new autoconf 2.52. That version is
2154 now required to compile the CVS trunk.
2156 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2158 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2159 to generally parse user@fqdn format strings. Affected file
2160 lib/silcutil/silcutil.c.
2162 * Added nickname_format and nickname_force_format fields to the
2163 SilcClientParams structure. The first one defines the format
2164 for the nicknames that the library will enforce if the receives
2165 multiple same nicknames. The second one is boolean value and
2166 can be used to force the library to always enforce the format
2167 to the nicknames regardles whether there are multiple nicknames
2168 or not. This configurable formatting was employed to flexibly
2169 support accessing multiple nicknames from the user interface.
2170 The userinterface can now set the nicknames to what ever format
2171 they prefer. Affected file lib/silcclient/silcapi.h.
2173 Added function silc_client_nickname_format to the file
2174 lib/silcclient/idlist.c. It performs the nickname formatting.
2176 Added new field `hostname´ to the SilcClientEntry context.
2177 It holds the hostname of the client. Affected file is
2178 lib/silcclient/idlist.h.
2180 * Irssi SILC Client sets the nicknames in nick@hostn format.
2181 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2182 irssi/src/silc/core/silc-core.c.
2184 The WHOIS printing now also shows both the real nickname and
2185 the formatted nickname so that user knows how to access the
2186 user if there are multiple same nicknames cached. Affected
2187 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2188 printing formatting too to take the hostname now as a separate
2189 argument. The Affected file is
2190 irssi/src/fe-common/silc/modules-formats.[ch].
2192 * Changed the silc_client_get_clients_local to accept the formatted
2193 nickname as argument. It accepts the real nickname too but the
2194 formatted nickname can be used to find the true entry from
2195 multiple entries. Affected file lib/silcclient/silcapi.h and
2196 lib/silcclient/idlist.c.
2198 * Added nickname_format_parse field to the SilcClientParams.
2199 It is a callback function provided by the application to parse
2200 the nickname out of the formatted nickname string. The library
2201 calls it to get the nickname from the formatted string. Since
2202 the application generally knows better the format of the nickname
2203 string it parses it instead of the library, even though library
2204 encodes the formatted string. If the callback function is not
2205 provided then the library will use the string as is. The
2206 affected file is lib/silcclient/silcapi.h.
2208 * All the nickname strings passed to the client library in
2209 commands are now expected to be formatted nickname strings.
2210 If the command does not support the formatted nickname string
2211 it will assume that the sent string is the actual nickname.
2212 Affected file lib/silcclient/command.c.
2214 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2216 * Added public key authentication support to OPER and SILCOPER
2217 commands in the client library. Affected file is
2218 lib/silcclient/command.c.
2220 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2222 * Changed the get_auth_methdod client operation to be asynchronous.
2223 It can be async if the application resolves the authentication
2224 method from the server during the negotiation. Added new
2225 SilcGetAuthMeth completion callback that the application will
2226 call after resolving the authentication method.
2228 Added function silc_client_request_authentication_method that
2229 the application can use to resolve the authentication method
2230 from the server. Added also SilcConnectionAuthRequest callback
2231 that the library will call after the server has replied. The
2232 application can call this function if it does not know the
2233 current authentication method.
2235 Affected files are lib/silcclient/client.c and
2236 lib/silcclient/silcapi.h.
2238 * The Irssi SILC client now automatically resolves the authentication
2239 method incase any configuration information is not present (and
2240 currently there never is). The affected file is
2241 irssi/src/silc/core/client_ops.c.
2243 * Fixed public key authentication from the client library.
2244 Affected file lib/silcclient/protocol.c. Changed also the
2245 protocol specification about the public key authentication in
2246 the connection authentication protocol. The actual data to be
2247 signed is now computed with a hash function before signing.
2249 * Fixed the public key authentication from the server as well.
2250 Affected file silcd/protocol.c.
2252 * Removed the mlock()'s from the memory allocation routines.
2253 Affected file lib/silcutil/silcmemory.c. The ./configure does
2254 not check anymore for the mlock(). Affected file is
2257 * Fixed USERS command in server to allow the execution of the
2258 command for private and secret channels if the client sending
2259 the command is on the channel. Affected file silcd/command.c.
2261 * Fixed silc_client_get_clients_local to return the clients
2262 count correctly. It could return wrong value. Affected file
2263 lib/silcclient/idlist.c.
2265 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2267 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2268 types. The assembler optimizations seemed not to like 64-bit
2269 data types. The assmebler optimizations thus are now enabled
2270 also for BSD systems as opposed to only enable them for Linux.
2272 * Do not check for threads at all on BSD systems. Affected
2273 file configure.in.pre.
2275 * Removed -n and -h options from the Irssi SILC Client since
2276 they are not used in silc.
2278 * Fixed the prime generation to assure that the first digit
2279 of the generated random number is not zero since our conversion
2280 routines does not like number strings that starts with zero
2281 digit. If zero digit is seen the random number is regenerated.
2282 This caused some corrupted RSA keys when the zero first digit
2283 was met. Affected file lib/silcmath/silcprimegen.c.
2285 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2287 * Fixed WIN32 configuration in the ./configure script.
2288 Fixed to include xti.h on environments that has it.
2289 Patches by Carsten Ilchmann and andrew.
2291 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2293 * Changed the silc_id_create_client_id to be collision
2294 resistant. It is now assured that there cannot be created
2295 two same client ID's. I suspect that some weird bugs in
2296 the server were actually caused by duplicate Client IDs.
2297 Affected file silcd/serverid.[ch]. A router receiving
2298 new ID now also assures and informs the sending server
2299 if the ID caused collision.
2301 * Changed the silc_id_create_channel_id to also assure that
2302 there are no collisions.
2304 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2306 * Statement about ignoring the Mutual Authentication flag when
2307 performing rekey with PFS was a bit misleading. It is ignored
2308 if it was set in the initial negotiation, it cannot be even
2309 set in the rekey. Fixed in the ke-auth draft. Started the
2310 new versions of the protocol drafts in the doc/.
2312 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2314 * Fixed a bug in silc_client_command_identify_save when saving
2315 new channel information. The channel name was no duplicated
2316 and caused crash on exit. Affected file is
2317 lib/silcclient/command_reply.c.
2319 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2321 * Fixed the getkey command handling in the server. Send just
2322 empty OK reply to the sender if the key could not be fetched
2323 (but everything else was ok, like the key just was not available).
2324 Changed the public key parameter to optional in the protocol
2325 specs so that empty OK reply can be sent. Affected file
2328 Added a message to Irssi SILC client to tell to user if the
2329 server did not return a public key.
2331 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2333 * Fixed a channel key regeneration bug. It registered new
2334 timeout tasks exponentially until all system resources were
2335 used. Affected file silcd/server.c.
2337 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2339 * Added the SILC Document generator to the scripts/silcdoc.
2340 It can be used to generate the Toolkit Reference Manual out
2341 of the source tree. Internally it will also use the RoboDoc
2342 generator now imported in util/robodoc.
2344 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2346 * Added couple of return's in rekey protocol if error orccurred
2347 during the protocol. The execution must be terminated.
2348 Affected file silcd/protocol.c. Also, terminate the protocol
2349 always with timeout.
2351 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2353 * The client's Client ID was created initally from the wrong
2354 nickname (it could have been in format nick@host) in the
2355 silc_server_new_client. Affected file silcd/packet_receive.c
2357 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2359 * Added some SILC_LOG_ERROR's to various error conditions
2360 if client could not be added to ID cache. Affected files
2361 silcd/packet_receive.c and silcd/server.c.
2363 * When client's sock->user_data is freed, NULL also the
2364 client->router and client->connection pointers. Added check
2365 for these pointers being NULL to various places around the
2366 code. Affected file silcd/server.c.
2368 * Added client->data.registered == TRUE checks to various
2369 places around the code to assure that unregistered client's
2370 are not handled when it is not allowed. Affected file
2373 * Added `bool registered' fields to all
2374 silc_idlist_[server|client]_get_* routines to indicate whether
2375 the fetched client needs to be registered or not. Affected
2376 file silcd/idlist.[ch].
2378 * Add your own entry as registered to the ID cache in the
2379 server. Affected file server.c.
2381 * Fixed a bug in silc_server_new_server. The SilcServer was
2382 set as the new server's context instead of SilcServerEntry.
2383 This naturally caused some weird bugs.
2385 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2387 * Do not delete the channel rekey task when adding it
2388 for in silc_server_create_channel_key.
2390 * Changed the silc_server_create_channel_key to return
2391 TRUE or FALSE to indicate the success of the channel key
2394 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2396 * Fixed MSVC++ project files and added missing files to
2397 Makefiles under win32/.
2399 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2401 * Do not add TCP_NODELAY flag if the operating system
2402 does not have it defined. Affected files are
2403 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2405 * Fixed buffer overflow from Irssi SILC Client. Affected
2406 file irssi/src/fe-common/core/themes.c.
2408 * Fixed double free in client library in the file
2409 lib/silcclient/client.c when disconnecting from server.
2411 * Applied double free patch from cras to Irssi SILC client.
2412 Affected files irssi/src/core/[modules/expandos].c
2414 * Fixed the disconnection handling to Irssi SILC Client.
2415 The application must call silc_client_close_connection
2416 in ops->connect client operation in case of failure of
2417 the connection. Affected file is
2418 irssi/src/silc/core/client_ops.c.
2420 * Do not set sock->protocol to NULL in the function
2421 silc_client_close_connection after executing the protocol's
2422 final callback since the sock might not be valid anymore.
2423 Affected file lib/silcclient/client.c.
2425 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2427 * Do not enable SILC_THREADS if the linking with libpthread
2428 did not happen. Affected file configure.in.pre.
2430 * Added notion to protocol specification that server must
2431 verify the sent authentication payload with CMODE when
2432 setting the channel founder key. Implemented it to the
2433 server. Affected file silcd/command.c.
2435 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2437 * Added _EXTRA_DIST SILC distribution variable to the
2438 distributions file. It is used to conditionally add extra
2439 files or directories to the specific distribution. Affected
2440 files ./prepare, Makefile.am.pre and distributions.
2442 Removed the `_' from the start of the distribution names.
2445 * Added README.WIN32 for instructions to compile the Toolkit
2448 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2450 * Fixed a double free in disconnection in the server. Affected
2451 file is silcd/server.c.
2453 * Fixed the lib/silcske/groups.c to work now also with GMP
2454 MP library. The string conversion did not work when using
2455 specific base and the base is indicated in the string as well.
2457 * Created win32/ directory which now includes MSVC++ specific
2458 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2459 It will appear only in the toolkit distribution
2461 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2463 * Changed the key material distribution function in case when
2464 the hash output is too short. The data is now concatenated
2465 a bit differently than it used to. Made the change to the
2466 SKE protocol specification.
2468 * Added better GMP detection to configure.in.pre. A patch
2471 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2473 * Fixed a minor bug in SKE that might cause some problem on
2474 some platforms. Affected file lib/silcske/silcske.c.
2476 * Added the cookie checking for initiator in the SKE. It checks
2477 that the responder returns the sent cookie unmodified. The
2478 affected file is lib/silcske/silcske.c. Added new SKE
2479 error type INVALID_COOKIE that can be sent during the
2480 negotiation. Fixed some memory leaks as well.
2482 * Added the "invalid cookie" error message to Irssi SILC client's
2485 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2487 * Added `task_max' field to the SilcClientParams to indicate
2488 the maximum tasks the scheduler can handle. If set to zero,
2489 default values are used. Affected file lib/silcclient/silcapi.h.
2491 * Fixed memory leaks in silc_client_close_connection. Affected
2492 file lib/silcclient/client.c.
2494 * Added silc_client_del_client_entry to client library to free
2495 all memory of given client entry. Affected file is
2496 lib/silcclient/idlist.[ch].
2498 * Added new functions silc_client_del_channel and
2499 silc_client_del_server to delete channel and server entries.
2500 Affected file lib/silcclient/[silcapi.h/idlist.c].
2502 * Removed silc_client_del_client_by_id from silcapi.h.
2504 * Fixed the INFO command to return the server's own info
2505 correctly when querying by Server ID. Affected file is
2508 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2510 * Removed the non-blocking settings in WIN32 code in the
2511 silc_sock_[read/write] and added SleepEx instead. Affected
2512 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2513 of input data is now checked with FIONREAD and ioctlsocket.
2515 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2517 * Call silc_schedule_task_del_by_context in the
2518 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2519 Affected file lib/silccore/silcprotocol.c.
2521 * Call silc_protocol_cancel for active protocols in the
2522 silc_server_close_connection if the funtion
2523 silc_server_free_sock_user_data has not been called.
2524 Affected file silcd/server.c.
2526 * Generic tasks cannot be deleted using the del_by_fd
2527 task deleting function since generic tasks does not match
2528 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2530 * Added a notion to SILCOPER help file that the SILCOPER works
2531 only on router server, not on normal server.
2533 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2535 * Added for WIN32 support for the new scheduler as well.
2536 Affected file lib/silcutil/win32/silcwin32schedule.c.
2538 * Fixed the SHA1 implementation to work on various platforms.
2540 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2542 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2543 API. It is part of the scheduler now. Everything else is
2544 as previously but some functions has changed their names.
2545 Checkout the lib/silcutil/silcschedule.h for the interface.
2546 Updated all applications to use the new interface. Affected
2547 files are lib/silcutil/silcschedule.[ch].
2549 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2551 * Found a bug in the SKE implementation. The HASH value,
2552 specified by the protocol, was not computed correctly. The
2553 public key of the responder was not added to the computation
2554 even though it is mandatory. Affected file lib/silcske/silcske.c.
2555 This unfortunately causes incompatibilities with older
2556 clients and servers.
2558 * Added WIN32 specific network init and uninit functions:
2559 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2560 the Winsock2. Affected file lib/silcutil/silcnet.h and
2561 lib/silcutil/win32/silcwin32net.c.
2563 * Set the socket always to nonblocking mode on WIN32 after
2564 reading data or writing data. Affected file is
2565 lib/silcutil/win32/silcwin32sockconn.c.
2567 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2569 * Fixed various compilation problems under WIN32. Affected
2570 files lib/silcutil/win32/silcwin32thread.c and
2571 lib/silcutil/win32/silcwin32schedule.c.
2573 * Removed all _internal.h #includes from public header
2574 files. Internal headers must never be included from
2577 Removed also the lib/silcske/payload_internal.h file.
2579 * All include files that may be needed (public and some others
2580 included by the public headers) by application developers are
2581 now copied to the ./includes directory. It does not copy any
2582 internal headers. Affected file Makefile.defines.pre and all
2583 Makefile.am's under lib/ and subdirs.
2585 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2587 * Do not change the ~/.silc directory's permissions automatically.
2588 Affected file irssi/src/silc/core/clientutil.c.
2590 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2592 * Do not cancel the protocol in silc_server_close_connection
2593 it might cause recursion. Now cancelled in the function
2594 silc_server_free_sock_user_data. Affected file silcd/server.c.
2596 * Fixed the silc_server_remove_clients_by_server to regenerate
2597 the channel keys correctly finally. Added also new function
2598 silc_server_remove_clients_channels to actually do it.
2599 Affected file silcd/server.c.
2601 * Fixed the silc_server_new_channel to not crash by giving
2602 wrong router to the new channel. Affected file is
2603 silcd/packet_receive.c.
2605 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2607 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2608 which is given as argument to the silc_client_alloc now.
2609 It can be used to configure the client and set various parameters
2610 that affect the function of the client.
2612 * The USERS command in server did not check whether the channel
2613 is private or secret. Affected file silcd/command.c.
2615 * Added new argument to the USERS command in protocol specification.
2616 The USERS command now can take the channel name as argument
2617 as well. Added support for this in client and server and
2618 updated the protocol specs.
2620 * Completed the GETKEY command in client. It can be now used
2621 to fetch also servers public key not only some clients.
2622 Affected files lib/silcclient/command[_reply].c.
2624 * Added silc_client_get_server to return server entry by the
2625 server name. Affected files lib/silcclient/silcapi.h and
2628 * Redefined the IDENTIFY command in protocol specification to be
2629 more generic. It now can be used to query information about
2630 any entity in the SILC Network, including clients, servers and
2631 channels. The query may be based either the entity's name
2632 or the ID. Added support for this in both client and server.
2634 Affected files silcd/command.c and lib/silcclient/command.c
2635 and command_reply.c.
2637 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2638 the _from_client and _from_server functions. Affected file
2641 * Added silc_client_get_channel_by_id_resolve to the file
2642 lib/silcclient/silcapi.h to resolve channel information by
2643 its ID. Added also silc_client_get_channel_by_id that
2644 does not resolve it from the server.
2646 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2648 * Added SilcServerEntry context into the client library
2649 to represent one server. The INFO command now allocates
2650 these to save the resolved server info. For now on the
2651 client library will also keep information about servers,
2652 connected and resolved with INFO.
2654 The INFO command now allocates the SilcServerEntry context
2655 and saves the server info there. The COMMAND_REPLY in
2656 the INFO now returns the parameters to application in
2657 same order as defined in the protocol specification.
2659 The entries are cached in the client->server_cache.
2661 * The INFO command is now issued after received the Client ID
2662 from the server. Affected file lib/silcclient/client.c.
2664 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2665 to the application as the mode changer might be server.
2666 It is guaranteed that NULL is not returned anymore to the
2667 application. Affected file lib/silcclient/client_notify.c.
2669 The ID Type is now also passed to the application so that
2670 it can check whether the returned entry is SilcClientEntry
2673 Added new function silc_client_get_server_by_id to return
2674 the server entry by ID. Affected files are the
2675 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2677 * Do not create the channel in the Irssi SILC Client when issuing
2678 the JOIN command but when received the sucessful JOIN command
2679 reply. Otherwise the channel might get created even though we
2680 could not join it. The Affected file is
2681 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2683 * Fixed a channel joining bug in router. The router must also
2684 check the channel modes, invite and ban lists etc. when serving
2685 the JOIN command sent by normal server. Affected file is
2686 silcd/command.c. The router now resolves the client's
2687 information from the server who sent the JOIN command if it
2688 does not know it, and processes the JOIN command only after
2691 * Changed the SilcCommandCb to take new argument; void *context2.
2692 Affected file lib/silccore/silccommand.h
2694 The second argument in the command callbacks in the server now
2695 includes the SilcServerCommandReplyContext if the command was
2696 called as pending command callback from the command reply.
2697 Otherwise it is NULL. When called as pending the status of the
2698 command reply will be checked and if it was erronous the
2699 error will be sent to the original sender of the command.
2700 This way the client always receives the error messages even
2701 though the server was actually the one who received the error
2702 when it resent the command to router, for example. Affected
2703 files silcd/command[_reply].[ch].
2705 * Fixed sending WHOWAS command's error message to client if
2706 the requested client could not be found. It was missing.
2709 * Changed the CMODE and CUMODE commands reply arguments in the
2710 protocol specification. The Channel ID is now sent in both
2711 of the commands to identify the channel. Implemented this
2712 new feature to the client and server. Affected files
2713 lib/silcclient/command_reply.c and silcd/command.c.
2715 * Made better checks for invite and ban lists in the JOIN
2716 command in server. Affected file silcd/command.c.
2718 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2720 * The server now performs the incoming host IP/DNS lookup
2721 using the silc_socket_host_lookup and thus does not block
2722 the server anymore. Affected file silcd/server.c.
2724 * Completed the multi-thread support for SILC Scheduler in
2725 the lib/silcutil/silcschedule.c.
2727 * Fixed the configure.in.pre to detect the pthread correctly
2730 * Fixed a deadlock in silc_task_queue_wakeup in the file
2731 lib/silcutil/silctask.c.
2733 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2735 * Added new function silc_schedule_wakeup that is used in
2736 multi-threaded environment to wakeup the main thread's
2737 schduler. It needs to be used when a thread adds a new task
2738 or removes a task from task queues. After waking up, the
2739 scheduler will detect the task queue changes. If threads
2740 support is not compiled in this function has no effect.
2741 Implemented the wakeup mechanism to both Unix and WIN32
2742 systems. Affected files are lib/silcutil/silcschedule.[ch],
2743 lib/silcutil/unix/silcunixschedule.c and the
2744 lib/silcutil/win32/silcwin32schedule.c.
2746 * Added new function silc_task_queue_wakeup to wakeup the
2747 scheduler by the specified task queue. Affected file
2748 lib/silcutil/silctask.[ch].
2750 * The silc_socket_host_lookup_start now wakes up the scheduler
2751 after adding the timeout task. Affected file is
2752 lib/silcutil/silcsockconn.c.
2754 * The silc_socket_host_lookup is synchronous now if the threads
2755 support is not compiled in. However, the callback is still
2756 called asyncronously through the scheduler, anyway. Affected
2757 file lib/silcutil/silcsockconn.c.
2759 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2761 * Added new function silc_socket_host_lookup to perform
2762 asynchronous IP and FQDN lookups for the socket connection.
2763 Affected files lib/silcutil/silcsockconn.[ch].
2765 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2767 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2768 that may or may not compile the mutex support in.
2770 Changed the silc_mutex_alloc interface. It allocates the
2771 mutex now to the sent pointer and returns TRUE or FALSE.
2773 Affected file lib/silcutil/silcmutex.h.
2775 * Wrote the SILC Task Queue interface to support multi-threads.
2776 Affected file lib/silcutil/silctask.[ch].
2778 * Wrote the SILC Scheduler to support multi-threads. Affected
2779 file lib/silcutil/silcschedule.c.
2781 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2783 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2784 in lib/silcutil/win32/.
2786 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2788 * Defined SILC Mutex API and SILC Thread API and implemented
2789 them for Unix. Affected files are
2790 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2791 lib/silcutil/unix/silcunixmutex.c and
2792 lib/silcutil/unix/silcunixthread.c.
2794 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2796 * Fixed the silc_server_remove_clients_by_server's channel
2797 key re-generation. The hash table handling was incorrect
2798 and would not work with many channels. Affected file is
2801 * Fixed some memory leaks around the server code.
2803 * Rewrote the silc_server_get_users_on_channel to support IPv6
2804 based Client ID's. Affected file silcd/server.c.
2806 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2807 specification. However, a separate document must be written
2808 to define the detailed signing procedure and the payload
2809 associated with the flag. Defined the flag to the
2810 lib/silccore/silcchannel.h as well.
2812 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2814 * Changed the dynamic tables to static size tables in the
2815 lib/silccrypt/silchmac.c.
2817 * Removed GCC dependencies from the code. A patch by cras.
2819 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2821 * Do not show the error "Error receiving packet bla bla"
2822 in server if it really was not an error (-2 means that reading
2823 is pending). Affected file silcd/server.c.
2825 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2827 * Fixed a possible crash in silc_server_remove_clients_by_server
2828 in silcd/server.c. Fixed there also some memory leaks.
2830 * Fixed the silc_idlist_replace_client_id. It could replace
2831 wrong key in the hash table. Affected file silcd/idlist.c.
2833 * Do not check whether there are global users on the channel
2834 if the channel->global_users is FALSE. Affected functions
2835 silc_server_remove_from_one_channel and
2836 silc_server_remove_from_channels in silcd/server.c. Also,
2837 do not check if the removed client is local as we can be
2838 sure that global client was not removed from the channel
2839 and checking for global users is not needed.
2841 * The silc_server_remove_clients_by_server now re-generates
2842 the channel keys correctly for those channels that had
2843 clients removed from them. Affected file silcd/server.c.
2845 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2847 * Found the reason of random crashes in the server. We weren't
2848 ignoring the SIGPIPE signal (which can be sent in write())
2849 and it crashed the server. Affected file silcd/silcd.c.
2851 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2853 * Assure that sock->user_data is not NULL in the function
2854 silc_server_packet_send in silcd/packet_send.c.
2856 * Disconnect the remote connection if it could not be added
2857 to any ID lists in the server. The affected file is
2860 * Check in silc_server_packet_send[_real/dest] that the
2861 socket is not disconnecting and ignore the data if it is.
2862 Affected file silcd/packet_send.c.
2864 * Define inline to __inline on native WIN32 compilation.
2865 Affected file includes/silcwin32.h.
2867 * Added some explicit type casts for inline code since MSVC
2868 require them. Affected files lib/silcutil/silcbuffer.h,
2869 lib/trq/silcdlist.h and lib/trq/silclist.h.
2871 * Print warning in log files from now on if the packet
2872 decryption fails. Affected file silcd/server.c.
2874 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2876 * Changed the `say' client operation's interface to accept
2877 new `type' argument to indicate the type of the message sent
2878 by the library. The application may filter the library's
2879 messages according the type. The affected file is the
2880 lib/silcclient/silcapi.h.
2882 * Added two new functions to lib/silcclient/silcapi.h:
2883 silc_client_del_client and silc_client_del_client_by_id.
2884 Affected file lib/silcclient/idlist.c.
2886 * Moved the clientincludes.h from includes/ to silc/ and
2887 serverincludes.h from includes/ to silcd/.
2889 * The modes for the CMODE and CUMODE are now passed as
2890 uint32 for application with COMMAND_REPLY. The affected
2891 file is lib/silcclient/command_reply.c.
2893 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2895 * /WHOIS without arguments shows client's own information.
2896 Affected file lib/silcclient/command.c.
2898 * Changed PING to not accept any arguments. The specs
2899 says that client can ping only the connected server so
2900 requiring an argument is not needed. Affected file is
2901 lib/silcclient/command.c.
2903 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2905 * Fixed a fatal bug in private message sending and reception
2906 encryption and decryption when using private message keys.
2907 The implementation was incorrect and did not follow the
2908 specification. It causd that some of the message were
2909 lost since it did not use the sending and receiving keys
2910 as the protocol suggests. This has been fixed and will cause
2911 incompatibilities with older clients when sending private
2912 message encrypted with private message keys. Affected files
2913 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2914 and various other in Irssi SILC Client.
2916 Added `responder' boolean argument to the functions
2917 silc_client_add_private_message_key[_ske] to indicate when
2918 the key is added as responder or initiator of the key
2921 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2923 * Removed the silc_ske_check_version function and created
2924 a SilcSKECheckVersion callback. Added also a function
2925 silc_ske_set_callbacks that is now used to set all SKE
2926 callbacks. The callback functions are not given to
2927 the SKE functions anymore, but this function is used to
2930 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2932 * Added `silc_version' argument to the silc_client_alloc
2933 to define the version of the application for the library.
2934 The library will use the version string to compare it
2935 against the remote host's (usually a server) version
2936 string. Affected file lib/silcclient/silcapi.h
2938 * Added the KE protocol context to Key Agreement context
2939 in client library so that we can abort the SKE if it
2940 is in process when we get timeout. Affected file is
2941 lib/silcclient/client_keyagr.c.
2943 * Do not resolve the client ID forever if it returns in the
2944 first time that such client does not exist. This was done
2945 for example with private message. Affected file is
2946 lib/silcclient/client_prvmsg.c.
2948 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2950 * Do not add regex.h for WIN32. The affected file
2951 includes/silcincludes.h.
2953 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2954 not work yet 100%. It generates the DLL's automatically
2955 when compiling with --with-win32 under cygwin.
2957 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2959 * lib/contrib/regex.c is not compiled on WIN32.
2961 * Added silc_net_get_socket_opt function to the
2962 lib/silcutil/silcnet.h.
2964 * Added includes/silcwin32.h for WIN32 specific includes
2967 * Do not use ptime structure or any of the posix process
2968 functions on WIN32 in lib/silccrypt/silrng.c.
2970 * Added silc_gettimeofday to provide generic function
2971 for struct timeval on all platforms. Added the function
2972 to lib/silcutil/silcutil.h.
2974 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2976 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2977 library as they clearly belong there. As a plus side we
2978 can make the actual socket connection routines platform
2981 Added also new generic function silc_socket_read and
2982 silc_socket_write (that used to be silc_packet_[read/write].
2983 The implementation of these are platform specific.
2985 * Added WIN32 specific routines of silc_socket_[read/write]
2986 to lib/silcutil/win32/silcwin32sockconn.c.
2988 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2990 * Added preliminary support for native WIN32 compilation under
2991 cygwin (using the -mno-cygwin option for GCC) to the
2992 ./configure.in.pre. The --with-win32 now prepares the
2993 compilation for native WIN32.
2995 * Rewrote the SILC Scheduler interface in the file
2996 lib/silcutil/silcschedule.h. The scheduler is now context
2997 based and does not have anymore any global static scheduler.
2998 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2999 and created lib/silcutil/win32 directory for WIN32 based
3002 * Added Unix specific network routines to the
3003 lib/silcutil/unix/silcunixnet.c and the old
3004 lib/silcutil/silcnet.c includes now only generic routines.
3006 Added WIN32 specific network routines to the
3007 lib/silcutil/win32/silcwin32net.c.
3009 * Added Unix specific utility functions from the
3010 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3012 * Added WIN32 SILC Scheduler to the file
3013 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3016 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3018 * Do not handle JOIN notify in the server if the target client
3019 is not registered (idata->registered == FALSE). The affected
3020 file is silcd/packet_receive.c.
3022 * Update the nickrec->founder in event_cumode in the Irssi SILC
3023 client. Affected file irssi/src/silc/core/silc-channels.c.
3025 * Fixed the CUMODE_CHANGE notify handling in the server when
3026 server and router are announcing their clients on channels.
3027 Now the mode changes are saved and notified correctly. The
3028 affected file is /silcd/packet_receive.c.
3030 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3031 They really did not replace the cache entry in the ID Cache.
3032 Now they do that. Affected file silcd/idlist.c.
3034 * Fixed the KICK notify handling in the Irssi SILC client to
3035 update the channel records so that the kicked client does not
3036 appear to be on the channel. The affected file is
3037 irssi/src/silc/core/silc-channels.c.
3039 * Always update the conn->current_channel when executing command
3040 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3042 * Fixed the KILL notify handling in Irssi SILC client to remove
3043 the killed client on all channels.
3045 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3047 * Fixed the silc_parse_command_line to remove extra spaces
3048 from the start and end of the arguments. Affected file is
3049 lib/silcutil/silcutil.c.
3051 * Cancel and free any active protocol in the function
3052 silc_server_close_connection. Affected file silcd/server.c.
3054 * Cancel and free any active protocol in the function
3055 silc_client_close_connction. Affected file is
3056 lib/silcclient/client.c.
3058 * Do not execute the KILL command for clients that are in
3059 history (ie. they are not in the network). Affected file is
3062 * Fixed KILL notify handling, client does not crash anymore.
3063 Affected file irssi/src/silc/core/silc-channels.c.
3065 * Reduced the default packet buffer size from 2048 to 1024 in
3066 lib/silccore/silcpacket.c.
3068 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3069 counter to the SKE context that is incresed when the SKE library
3070 performs async operation outside the library. If the outside
3071 process frees the SKE context and FREED status will be set
3072 and the library will detect after the sync operation that the
3073 libary is freed. The affected files are
3074 lib/silcske/silcske[_status].[ch].
3076 * Resolve the client entry information in the function
3077 silc_client_channel_message to assure that NULL pointer is not
3078 passed as client entry to the application. */
3080 * Fixed the task timeout calculation to assure that there is
3081 never negative timeouts. The affected file is
3082 lib/silcutil/silcschedule.c.
3084 * Fixed the channel user mode notification sending in server.
3085 It was sent point-to-point to the router (or to server by router)
3086 but it needs to be destined to a channel. The routines now
3087 supports sending the channel user mode notifys to the channels
3088 when announcing clients and channels. Affected files are
3089 silcd/server.c and silcd/packet_receive.c.
3091 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3092 It did not actually replace the old channel entry in the cache.
3093 Affected file lib/silcclient/client_notify.c.
3095 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3097 * Fixed a possible crash in silc_packet_send_prepare. It now
3098 assures always that there is enough space in the buffer and
3099 at the tail area of the buffer (for MAC).
3101 Fixed the inbound buffer reallocation in silc_packet_read.
3102 It was old code and did not handle the reallocation correctly.
3105 The affected file is lib/silccore/silcpacket.c.
3107 * Fixed buffer overflow in silc_parse_nickname in the file
3108 lib/silcutil/silcutil.c.
3110 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3112 * make install generates new server keys only if there is not
3115 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3117 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3118 Added check that if the NOREPLY is set then we will not send
3119 the away message. This avoids infinite loop of away messages
3120 if both clients are away. The affected file is
3121 lib/silcclient/client_prvmsg.c.
3123 * Fixed client crash if /NICK was given without arguments.
3124 Affected file lib/silcclient/command.c.
3126 * Server does not send the invite list in INVITE command back
3127 to the client if the list was not altered. Added this notion
3128 to the protocol spec as well. Affected file silcd/command.c.
3130 Fixed possible crash in INVITE command by checking the
3131 value of silc_server_get_client_route command.
3133 * Fixed the INVITE notify type handling. The arguments are now
3134 taken in correct order and client does not crash. The affected
3135 file is irssi/src/silc/core/silc-channels.c.
3137 Removed the "Inviting xxx to channel" message from the
3138 client library away and let the application handle it.
3139 Affected file lib/silcclient/command.c. Added that message
3140 to Irssi SILC client's message formats.
3142 * Fixed CMODE command crash in client. It now checks the
3143 amount of arguments correctly and does not crash. The affected
3144 file is lib/silcclient/command.c.
3146 * Do not create new channel automatically in silc_channels_join
3147 but check whether the channel by that name already exists.
3148 Affected file irssi/silc/core/silc-channels.c.
3150 * Do not send the SERVER_SIGNOFF to router if the disconnected
3151 entity was the router. Affected file silcd/server.c.
3153 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3154 SILC client as it was missing from there.
3156 Added the handling of the KICK notify to the Irssi SILC client
3157 as it was missing. Added "you have been kicked" message to
3158 Irssi SILC client's message modules formats.
3160 Added the handing of the KILL notify to the Irssi SILC client
3161 as it was missing. Added the kill message module formats
3164 The affected file is irssi/src/silc/core/silc-channels.c.
3166 * The router did not save the channel mode the server announced.
3167 Affected file silcd/packet_receive.c.
3169 * Fixed a possible crash in INFO command in server. If the
3170 server did not provide the server info it crashed. Affected
3171 file silcd/command.c.
3173 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3175 * Fixed the GETKEY command in the server to check also the
3176 global list. Otherwise the GETKEY would not work correctly
3177 in normal SILC server. Affected file silcd/command.c.
3179 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3181 * Fixed GETKEY crash, it crashed if the command did not succseed.
3183 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3185 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3186 is now real and not just an macro interface to GMP.
3188 Removed the entire GMP from the source tree and imported new
3189 NSS MPI library instead. Reason for removing GMP is that it is
3190 extremely large and compiles extremely slow. The NSS MPI
3191 is only a few files and compiles in less than 10 seconds.
3192 The speed is also about the same as GMP. The MPI is imported
3193 to lib/silcmath/mpi.
3195 If the system has GMP installed we will still use the GMP.
3196 If it is not then the NSS MPI will be compiled.
3198 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3200 * Merged a long nickname (127 characters long) crash bugfix from
3201 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3203 * Merged a freed memory reference bugfix from Irssi CVS tree.
3204 Affected file irssi/src/core/commands.c.
3206 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3208 * Added the server's public key sving and verification to the
3209 server when performing the SKE. This was missing and the
3210 remote server's (or router's) public key was accepted without
3211 checking whether we have it previously or trust it at all.
3212 Affected file silcd/protocol.c.
3214 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3216 * Check in the silc_server_timeout_remote if protocol is active
3217 and make sure that the protocol's final callback is called so
3218 that all memory if freed. Affected file silcd/server.c.
3220 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3222 * silc_server_whois_send_reply crashed the server if the nickname
3223 was 127 characters long. Affected file silcd/command.c.
3225 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3227 * Added sanity check to the silc_server_new_client. If the hostname
3228 is provided inside username then check that the provided hostname
3229 really is the same as the resolved one. If the hostname was not
3230 resolved then check it from the public key. Affected file is
3231 silcd/packet_receive.c.
3233 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3234 if the server disconnected us and the connection is not valid
3235 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3237 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3238 the library to the lib/silcutil/silcutil.[ch].
3240 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3242 * Close log file after open. Affected file
3243 lib/silcutil/silclog.c.
3245 * Check whether sock == NULL in silc_client_send_packet and return
3246 if it is. Affected file lib/silcclient/silcclient.c.
3248 * Check rec->entry == NULL in the Irssi SILC Client before
3249 sending the channel message. Affecte file is
3250 irssi/src/silc/core/silc-servers.c.
3252 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3254 * Merged a splitted window bugfix from Irssi CVS tree. The
3255 affected file is irssi/src/fe-text/textbuffer-view.c.
3257 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3258 It did not print nickname.
3260 * Improved the distributions system a bit.
3262 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3264 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3265 irssi/src/fe-text/gui-window.c.
3267 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3268 to in-active server. The affected file is
3269 irssi/src/silc/core/client_ops.c.
3271 * Resolve the client in USERS command reply if the entry does
3272 not have username resolved. The affected file is
3273 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3274 command to WHOIS command to really resolve stuff. The USERS
3275 is not used any more in any critical section so WHOIS can
3276 be used even though it might be slower than IDENTIFY.
3278 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3281 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3283 * Changed the protocol API a bit more consistent in the
3284 lib/silccore/silcprotocol.[ch].
3286 * Changed the following headers to ROBODoc format:
3288 lib/silccore/silcpayload.h
3289 lib/silccore/silcprotocol.h
3290 lib/silccore/silcsockconn.h
3292 All core library headers are now formatted.
3294 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3296 * Fixed a bug in Irssi SILC client; do not show that you are
3297 server/router operator if you really are not. Affected file is
3298 irssi/src/silc/core/client_ops.c.
3300 * Renamed silc_command_free_payload to silc_command_payload_free.
3301 Affected file lib/silccore/silccommand.h
3303 * Added silcmath.h to include the prototoypes of various routines
3304 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3307 * Changed the following headers to ROBODoc format:
3309 lib/silccore/silcchannel.h
3310 lib/silccore/silccommand.h
3311 lib/silccore/silcid.h
3312 lib/silccore/silcidcache.h
3313 lib/silccore/silcmode.h
3314 lib/silccore/silcnotify.h
3315 lib/silccore/silcpacket.h
3316 lib/silcmath/silcmath.h
3318 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3320 * Added checking to the server code not to start the server if
3321 ciphers and stuff are not configured properly. Affected files
3322 silcd/serverconfig.[h] and silcd/server.c.
3324 * Changed the layout of the header files of the public interfaces
3325 in the SILC libraries. The new layout supports ROBODoc
3326 documentation tool (and some others) so that it is easy to create
3327 a library reference manual. All the other headers and source
3328 code must still follow the CodingStyle document. Also source
3329 code must not include these ROBODoc stuffs, only the headers.
3330 Furthermore, all public interface headers must now be named
3331 by using `silc' prefix, example: silcapi.h, silccipher.h.
3332 Some files were renamed due to this. All the other headers
3333 must not be used as public interfaces. I will update the
3334 CodingStyle document later. Changed following headers, so far:
3336 lib/silcclient/silcapi.h
3337 lib/silccore/silcauth.h
3338 lib/silccore/silcprivate.h
3339 lib/silccrypt/silcdh.h
3341 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3345 * Removed silc_client_packet_send_flush from the client library
3346 as it is not needed. Affected file lib/silcclient/client.[ch].
3348 * Added printing of message of unresolved authentication method
3349 to the Irssi SILC client. Added it to the module formats.
3350 Removed the same message from the client library.
3352 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3354 * Added new distribution feature, DISTLABEL. Every distribution
3355 can define own preprocessor label that can be used in the
3356 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3357 file distributions, acconfig.h.pre and prepare.
3359 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3361 * Added Makefile.defines_int to include the actual definitions
3362 for Makefile.defines.in. Tested the new distribution system,
3363 created distributions and tested installation.
3365 * Added AWAY message printing to the Irssi SILC client. Added
3366 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3368 * Added SCONNECT command to call the SILC's CONNECT command.
3369 Cannot use CONNECT directly since Irssi uses that internally.
3370 Affected file irssi/src/silc/core/silc-servers.c.
3372 Added ACTION local command. It is same as ME command but takes
3373 the channel as mandatory argument.
3375 Rewrote some of the Irssi's help files to suite for SILC
3378 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Added Makefile.defines[.in] that should for now on be included
3381 in all Makefile.am file in the source tree. That file includes
3382 all common compilation definitions for SILC source tree.
3384 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3386 * Minor changes to the ./prepare script to change the package
3387 name according the distribution name to the configure.in.
3389 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3391 * Created new distribution system. Added file `distributions'
3392 that defines all the distributions that can be created out of
3393 the SILC source tree. The ./prepare script now reads that
3394 file to determine how to prepare the distributions. The
3395 first argument to the ./prepare is the name of the distribution
3396 and second is the version of the distribution. If given
3397 without arguments it creates the default (toolkit) distribution
3398 with the default version (defined in ./prepare).
3400 All Makefile.am files that are subject to the distributions
3401 are now named as Makefile.am.pre. These are ./Makefile.am
3402 and lib/Makefile.am. Others may be changed later.
3404 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3406 * Added invite list, ban list, some key management and connection
3407 error message printing to module formats in the Irssi SILC client.
3409 * Added new silc_client_set_away_message to set the away message
3410 that is back to the person who sent private message. The
3411 affected file lib/silcclient/silcapi.h and the
3412 lib/silcclient/client_prvmsg.c.
3414 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3416 * Fixed the private message sending in the Irssi SILC client,
3417 added local command KEY to the Irssi SILC client.
3419 Added key management and key agreement message formats to the
3420 irssi/src/fe-common/silc/module-formats.[ch].
3422 Added USERS (alias WHO) printing, server/router operator
3423 indication and LIST command printing to the module formats.
3425 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3427 * Fixed channel joining notify handling, cumode notify handling
3428 from Irssi SILC client.
3430 * Added SILC specific module-formats to the Irssi SILC client so
3431 that SILC specific message hilighting, colors etc is possible.
3432 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3434 Added channel mode, channel user mode, actions, notices,
3435 whois and whowas printing to the the module-formats.c.
3437 * Fixed a bug in channel deletion in the server. The channel
3438 is not left to the cache even if the channel founder auth mode
3439 is set when there are no users anymore on the channel. Affected
3440 file silcd/server.c.
3442 * The silc_net_localhost now resolves the entire hostname including
3443 the domain name. Affected file lib/silcutil/silcnet.c.
3445 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * Changed the ask_passphrase client operation to be ascynchronous.
3448 It has now a completion callback and a context that the
3449 application must call after it has got the passphrase from
3450 the user. Affected files lib/silcclient/silcapi.h,
3451 lib/silcclient/protocol.c, lib/silcclient/command.c and
3454 Added SilcAskPassphrase callback that the application calls
3455 to deliver the passphrase to the library.
3457 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3458 The public key verification and especially a certificate
3459 verification is asynchronous procedure.
3461 Added new SILC_SKE_STATUS_PENDING status to indicate the
3462 request is pending and a callback will be called to finalize
3465 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3466 indicate that remote end did not send its public key (or
3467 certificate), even though we require it. Added check for this
3468 condition in the SKE. This was a security bug, now fixed.
3470 Defined new SilcSKEVerifyCbCompletion callback that is called
3471 when the verification process is completed.
3473 The affected files lib/silcske/silcske_status.h and
3474 lib/silcske/silcske.[ch].
3476 * Changed the verify_public_key client operation to be async
3477 as well. Defined SilcVerifyPublicKey callback that is used to
3478 indicate the success of the public key verification process.
3480 Changed the server and client to use the new async client
3483 * Changed the Irssi SILC client's internal scheduler to be called
3484 twice as many times as it used to be. As a result the client
3485 should be a bit faster now. Affected file is
3486 irssi/src/silc/core/silc-core.c.
3488 * Added support to Irssi SILC client of asynchronous public key
3489 verification and passphrase inquiry. Affected file is
3490 irssi/src/silc/core/silc-core.c.
3492 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3494 * Do not say "You have left channel %s" in client library.
3495 Moved it to the application. Affected files are
3496 lib/silcclient/command.c and silc/client_ops.c.
3498 * Fixed silc_client_get_clients. Command context was not
3499 duplicated and was freed memory in the callback. Affected
3500 file lib/silcclient/idlist.c.
3502 * Do not say "you are now talking..." on JOIN command in the
3503 client library. The appliation must handle it.
3505 * Do not say ".. changed topic to" in command reply in the
3506 client libary. The application must handle it.
3508 * Fixed TOPIC command sending in the client library.
3510 * Fixed a memory leak in silc_client_command_free in the file
3511 lib/silcclient/command.c.
3513 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3515 * Imported a modified version of Irssi client to the source tree.
3516 The Irssi will be used to create a new client called
3517 Irssi SILC. Imported to irssi/.
3519 Added silc_core_init_finish function to the Irssi. Affected
3520 file irssi/configure.in.
3522 A lot changes in the Makefile.ams around the irssi tree.
3524 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3526 * Do not rehash if the new size is same as the old size of the
3527 hash table, in the silc_hash_table_rehash*. The affected file
3528 lib/silcutil/silchashtable.c.
3530 * Replaced hash_table_del_by_context calls from the server
3531 (when channel->user_list and client->channels) to the
3532 hash_table_del as it is sufficient and faster.
3534 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3536 * Added silc_hash_table_list, silc_hash_table_get and the
3537 SilcHashTableList structure to provide an alternative way to
3538 traverse the hash table. The affected files are
3539 lib/silcutil/silchashtable.[ch].
3541 * Changed the server's idlist routines to use the hash table
3542 routines to optimize the code.
3544 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3546 * Replaced the client entry's `channel' list and channel entry's
3547 `user_list' list to hash tables for optimized lookup. Changed
3548 the code to use the hash table interface around the code.
3549 Affected file lib/silcd/idlist.[ch].
3551 * Added `auto_rehash' boolean argument to the function
3552 silc_hash_table_alloc to indicate whether the hash table should
3553 auto-rehash when it thinks is appropriate time. It will
3554 increase the hash table size if the there is twice as much
3555 entries in the table than the size of the table, and will
3556 decrease the size if there are twice as less entries than
3557 the size of the table.
3559 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3561 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3563 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3565 * silc_idcache_purge_by_context deletes the entry now by context
3566 as it is supposed to do. Affected file lib/silccore/idcache.c.
3568 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3569 client is not anymore valid (WHOWAS givens the info) and not
3570 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3572 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Removed the `data' and `data_len' arguments from the ID Cache
3575 interfaces and added `name' argument. ID Cache does not handle
3576 anymore the binary data only a names associated with given ID.
3578 * When hashing a Client ID with silc_hash_id the entire ID is
3579 not hashed anymore, instead only the hash of the Client ID is
3580 hashed. This way we can access the Client ID from the cache
3581 with Client ID but with the hash of the ID (which is a hash of
3582 the nickname) as well without any difference in performance.
3584 Added also silc_idcache_find_by_id_one_ext to do one on one
3585 searching when we have the actual ID. Added also function
3586 silc_hash_client_id_compare. The affected files are
3587 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3589 * When hashing the name associated with a ID it is always done
3590 in lowercase. This way we can access the cache without worrying
3591 about case-sensitivity, even though, for example nicknames are
3594 * Fixed a bug in server with channel message sending. It put
3595 wrong ID type as destination ID. The affected file
3596 silcd/packet_send.c.
3598 * silc_idcache_del_by_context now deletes from all hash tables
3599 by context. Affected file lib/silccore/idcache.c.
3601 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3603 * Changed the client library to use the new ID Cache interface.
3604 Changes around the source tree.
3606 * Added silc_hash_table_rehash_ext to rehash with specific
3607 hash function. Affected file lib/silcutil/silchashtable.[ch].
3609 * Added silc_hash_string_compare to compare two strings in the
3610 hash table. Affected file lib/silcutil/silcutil.[ch].
3612 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3614 * Added new function silc_idcache_del_by_context into the
3615 lib/silccore/idcache.[ch].
3617 * Changed the server's ID list routines to use the new ID Cache
3618 interface. Changes around the source tree.
3620 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * Added silc_hash_table_del[_by_context]_ext functions in to the
3623 lib/silcutil/silchashtable.[ch].
3625 Removed silc_hash_table_find_all* routines and added new
3626 silc_hash_table_find_foreach to replace them.
3628 Added silc_hash_table_replace_ext function as extended
3629 replacing function. Separated the simple hash table interface
3630 from the extended hash table interface in the file
3631 lib/silcutil/silchashtable.h.
3633 * Fixed minor bugs and changed it to use some of the new
3634 hash table functions in lib/silccore/idcache.c
3636 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3638 * Added new function silc_hash_table_find_all to return all keys
3639 in the hash table by the specified key. As the hash table is
3640 collision resistant it also makes it possible to have several
3641 duplicate keys in the hash table. This function may be used to
3642 find all of the keys from the hash.
3644 Added user_context arguments to the SilcHashFunction,
3645 SilcHashCompare and SilcHashDestructor to deliver user specified
3648 Added new fuctions silc_hash_table_find[_all]_ext to do
3649 extended lookup with specified hash and compare functions and
3650 specified user contexts.
3652 Added new function silc_hash_table_add_ext to add the key
3653 with specified hash function and user context.
3655 Added new function silc_hash_table_foreach to traverse all
3656 entrys in the hash table. Added SilcHashForeach callback
3659 Added new function silc_hash_table_del_by_context to delete
3660 the entry only if the context associated with the key matches.
3662 Affected files are lib/silcutil/silchashtable.[ch].
3664 * Removed silc_hash_[server/client/channel]_id and added just
3665 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3666 silc_hash_id_compare to compare two ID's using as the hash table
3667 comparison function. Added also silc_hash_data to hash
3668 binary data and silc_hash_data_compare to compare it.
3670 * Removed silc_idlist_find_client_by_hash as it is not needed
3671 anymore. Affected file silcd/idlist.[ch].
3673 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3674 to use internally the SilcHashTable. The new ID Cache is a lot
3675 faster than the old one. Some of the ID Cache interface was also
3676 rewritten and obsolete and stupid functions were removed.
3678 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3680 * Added entry_count field to the SilcHashTable to keep the number
3681 of the entries in the table. Implemented the function
3682 silc_hash_table_rehash. Added new function
3683 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3685 Fixed a minor bug in silc_hash_table_free.
3687 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3688 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3689 into the lib/silcutil/silcutil.[ch].
3691 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3693 * Implemented a collision resistant hash table into the
3694 lib/silcutil/silchashtable[ch]. See the header and the source
3695 for the SilcHashTable API.
3697 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3699 * Merged dotconf version 1.0.2 into lib/dotconf.
3701 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3703 * Do not compile anything in lib/silcsim/* if the SIM support
3704 is not enabled. The tree should now compile without problems
3707 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3709 * Compiled the SILC under cygwin. Compiled and tested briefly
3710 without problems. More tests needed. The SIMs didn't compile
3713 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3715 * Fixed possible crash in silc_get_username in the
3716 lib/silcutil/silcutil.c.
3718 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Fixed a va_arg in silc/client_ops.c.
3722 * Oops, RC5 routines were named AES and caused some problems
3723 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3725 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * Added new SilcIDIP structure into the lib/silccore/id.h and
3728 replaced the old `ip' fields from all SILC ID's to that type.
3729 This is a step towards IPv6 support.
3731 The silc_id_get_len takes now the ID as an extra argument.
3732 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3733 both IPv4 and IPv6 based ID's.
3735 The affected files are lib/silccore/id.[ch] and other files
3736 around the tree using these routines.
3738 * Removed the ID length arguments in server from various
3739 silc_server_send_notify_* routines -> they are not needed
3742 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * Fixed memory leak in silc_encode_pem_file in the file
3745 lib/silcutil/silcutil.c.
3747 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3749 * Check minor version as well in the SKE. Affected files are
3750 silcd/protocol.c and lib/silcclient/protocol.c.
3752 * Added --identifier option to the server so that an identifier
3753 can be when creating the public key for the server. Affected
3754 file is silcd/silcd.c.
3756 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3757 lib/silccrypt/silcpkcs.c.
3759 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3761 * Register default ciphers and stuff when using -C option with
3762 the server. Affected file sildc/silcd.c.
3764 * Put back the servers public key filename format, it is better
3765 than the new one. For now, the client keys are saved with the
3766 new filename format. The affected file silc/client_ops.c.
3768 * Implemented the Cipher API for the rest of the ciphers that
3769 did not implement it or implemented it the wrong way.
3771 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3773 * Register default ciphers and stuff when using the -S option
3774 in the client. Affected file silc/silc.c. Same also when
3775 creating new key pair with -C option.
3777 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3779 * Fixed the silc_verify_public_key client operation function to
3780 save the public keys differently. The fingerprint is now
3781 used as filename and not the hostname. This way also the
3782 client keys are saved uniquely and not with hostnames. The
3783 affected file is silc/client_ops.c.
3785 * Trimmed the silc_hash_fingerprint function to remove extra
3786 whitespaces from the end of the fingerprint. The affected
3787 file is lib/silccrypt/silchash.c.
3791 * Added silc_cipher_register_default function to register all
3792 default ciphers. It can be used when configuration files
3793 does not exist and the application does not want any specific
3794 ciphers in any specific order.
3796 The SilcDList is now used as silc_cipher_list dynamically
3797 allocated cipher list. Removed the static list all together
3798 and now all ciphers must be allocated to the dynamic list.
3799 The silc_cipher_alloc routine was changed to check only the
3802 All silc_cipher_* routines that used to return int returns
3805 The affected files lib/silccrypt/silccrypt.[ch].
3807 * The same thing was done to silc_hash_* as for silc_cipher_*
3808 routines. Affected files lib/silccrypt/silchash.[ch].
3810 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3811 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3812 Added also silc_pkcs_[un]register[_default] functions.
3813 Removed the data_context from the PKCS API.
3815 * Added silc_hmac_register_default function to register default
3816 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3817 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3818 to unregister all hmacs at once.
3820 * Register the default ciphers, hash functions, PKCSs and HMACs
3821 if client's configuration file does not exist. The affected
3824 * The client did not load the hash functions from the SIM
3825 modules at all. Added support for this. Affected file is
3826 silc/clientconfig.c.
3828 * When decoding public key with silc_pkcs_public_key_decode, check
3829 the supported algorithm only if PKCS are registered. Affected
3830 file lib/silccrypt/silcpkcs.c. The same was done with the
3831 silc_pkcs_private_key_decode.
3833 * Fixed the SILC List routines to keep the list always in order.
3834 It used to change the list's order when traversing the list but
3835 not it preserves the order. Affected file lib/trq/silclist.h.
3837 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3839 * Added the client library to use the SilcSocketConnection's
3840 reference counter (by silc_socket_dup) to prevent the bug that
3841 the socket object may be freed underneath async operation.
3843 * The name resolv library checking fixes in the configure.in.pre.
3846 * Created new version of the protocol drafts for future
3847 development. The -03 drafts are the ones that will be changed
3848 in the trunk now and the -02 will remain as they are.
3850 * Send list of CUMODE notifys to the router when announcing
3851 the channel users to the router. Affected file silcd/server.c.
3852 If the router receiving channel founder CUMODE for a channel
3853 that already has channel founder it will send CUMODE notify
3854 to the sender to remove the channel founder rights from the
3855 announced client. Affected file silcd/packet_receive.c.
3857 * The CUMODE notify may now use Server ID as well as the entity
3858 who changes the mode. Updated protocool specs.
3860 * Updated INSTALL and README files.
3862 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * New web pages in the http://silc.pspt.fi. The pages was
3869 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * Implemented the [DenyConnectin] config section in the server.
3872 Added silc_server_config_denied_conn to check whether incoming
3873 connection is denied. Affected file silcd/serverconfig.[ch].
3875 * Do not check the ports when checking the incoming configuration
3876 data if the port is 0, meaning any. Affected file is
3877 silcd/serverconfig.c.
3879 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3881 * Fixed buffer overflow in silc_string_compare in the file
3882 lib/silcutil/silcutil.c.
3884 * Fixed double free in silc_server_command_leave in the file
3887 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3889 * Fixed the version checking in the server. Affected file is
3892 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3894 * Fixed the configuration data fetching when accepting new
3895 connections in the server. Affected file silcd/server.c.
3897 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3899 * Added `sender_entry' argument to the function
3900 silc_server_packet_relay_to_channel so that we can check
3901 whether some destination actually belongs to the same route
3902 the sender belongs (ie, we must not resend the packet to the
3903 sender). Affected file silcd/packet_send.[ch].
3905 * Added `servername' field to the SilcClientEntry in the server
3906 to hold the name of the server where client is from. Affected
3907 file is silcd/idlist.h.
3909 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3911 * Moved the channel message encrypting in the router betwen
3912 router connections from silc_server_channel_message to the
3913 silc_server_packet_relay_to_channel since we want to check
3914 whether we have anybody channel before encrypting anything.
3915 Affected files silcd/packet_[receive/send].c.
3917 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3919 * Fixed the [AdminConnection] server config section to support
3920 multiple entries. Affected file silcd/serverconfig.c.
3922 * Added support into the server to check the validity of the
3923 incoming connection before executing any KE or authentication
3926 * The connection configuration is now saved to the KE and
3927 connection auth protocol contexts and not fetched anymore in
3928 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3930 * The local hosts listenning address and port is also resolved
3931 now when starting the server. We want to have the socket object
3932 to include the real address and port for the listener. Added
3933 new function silc_net_check_local_by_sock into the files
3934 lib/silcutil/silcnet.[ch].
3936 * Fixed a broadcast bug in server -> do not broadcast if we
3939 * Fixed a routing bug. Do not route broadcast packets ever.
3940 Broadcast packets must be processed always and not routed since
3941 they may be destined to some other host than yourself and thus
3942 would get routed without no good reason. Affected file is
3945 * Added function silc_server_config_is_primary_route to check
3946 whether primary router connection has been configured (a router
3947 configuration that we are initiating). If there is not, we
3948 will assume that there is only two routers in the SILC network
3949 and we will use the incoming router connection as our primary
3950 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3952 * Changed the order of the broadcasting. Broadcast _after_ the
3953 packet has been processed not before. Affected file is
3956 * Fixed a [ClientConnection] parsing bug. The port was never
3957 parsed correctly thus resulting to port 0. Affected file
3958 silcd/serverconfig.c.
3960 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3961 argument and did not set the broadcast packet flag. Affected
3962 file silcd/packet_send.c. Fixed same bug in the function
3963 silc_server_send_notify as well.
3965 * If we receive NEW_ID packet for our own ID in the server, ignore
3968 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3972 * Removed the nickname from the Private Message Payload.
3973 Updated the code and the protocol specs.
3975 * Updated protocol specs for submitting to the IETF.
3977 * Tweaked the Random Number Generator a bit. Affected file
3978 lib/silccrypt/silcrng.c. Exported a new function
3979 silc_rng_[global]_add_noise which can be used to add more
3982 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3984 * Do not parse packets with different timeout when protocol
3985 is active -> may cause problem with rekey. Affected file
3988 * When server receives signoff notify it must not create
3989 new channel key if the client is on any channels since the
3990 sender of the signoff notify will create it.
3992 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3994 * Added printing of error messages during SKE protocol from the
3995 failure packet sent by server during SKE. Affected file
3998 * Removed the client's failure_callback handling with timeout
3999 and handle it immediately when received.
4001 * The SKE library returned wrong type in SUCCESS and FAILURE
4002 packets. They must be 32 bit MSB not 16 bit MSB.
4004 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4006 * Ok, rewrote the logic of the re-key and now it seems to work.
4007 I tested it on high traffic with frequent re-keys without
4008 problems. Added hmac_receive (and renamed hmac to hmac_send)
4009 in SilcClientConnection in lib/silcclient/client.h and
4010 in SilcIDListData in silcd/idlist.h. Also, removed the
4011 SilcPacketParserContext's cipher and hmac fields as they are
4012 not needed anymore and actually caused some problems when
4013 the ciphers and hmac's changed underneath the packet parser.
4015 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4017 * If re-key protocol is active then process the incoming packets
4018 synchronously since we must assure that icoming packets encrypted
4019 with the old key is processed before the new keys is set to
4020 use. This is true other packets than for REKEY packets.
4021 Affected file silcd/server.c. The same was done to client library
4022 as well, affected file lib/silcclient/client.c.
4024 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4026 * Fixed bug in client and server to accept the force send if
4027 the packet is send from silc_[server/client]_packet_process
4028 function. Otherwise the packets are never delivered, oops.
4030 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4032 * Disable force sending of packets when REKEY protocol is active.
4033 We must assure that no packet is sent directly when rekey is
4034 performed. All packets must be sent through packet queue.
4035 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4036 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4037 function is silc_[server/client]_packet_send_real to check
4040 * Replaced the SIM paths from example config files to
4041 /usr/local/modules. Also, make install creates now
4042 /usr/local/silc/logs directory to hold all the SILC server
4045 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * Made the configure.in.pre work on Solaris. Patch by salo.
4049 * Made all ciphers compatible with non-x86 machines. Defined
4050 CBC mode macros into lib/silccrypt/ciphers_def.h.
4052 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4054 * Fixed the make install.
4056 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4058 * When MAC computation fails the silc_packet_decrypt returned 0
4059 even though it was supposed to return -1. Fixed this. The
4060 affected file is lib/silccore/silcpacket.c.
4062 * Do not replace the config files in /etc/silc (in make install)
4063 if they already exist. Affected file ./Makefile.am.
4065 * Do not send re-key packets immediately but through packet queue.
4066 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4068 * Changed silc_net_check_host_by_sock to return FALSE if the
4069 IP/DNS could not be resolved. Though, it returns the IP address
4070 now even if it could not resolve it (but returns also FALSE).
4071 Affected file lib/silcutil/silcnet.[ch].
4073 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4075 * Added silc_pkcs_decode_identifier to decode the public key's
4076 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4077 Added also silc_pkcs_free_identifier. Added also new context
4078 SilcPublicKeyIdentifier.
4080 * Added -S option to the silc client. It is used to dump the
4081 contents of the specified public key file.
4083 * Changed the PKCS api to return the public key length when
4084 setting the public key.
4086 * Fixed a fatal bug in the public and private key file loading.
4087 Affected file lib/silccrypt/silcpkcs.c.
4089 * Execute the packet parsing for client with zero (0) timeout
4090 if the protocol is active. Affected file silcd/server.c.
4092 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4094 * Made the key generation options to the silcd program. Added
4095 -C option, equivalent to client's option.
4097 * Added new [ServerKeys] config section to the server. It
4098 configures the server's public and private key.
4100 * Defined generic Public Key Payload into the protocol
4101 specification to send specific type of public keys and
4104 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4105 public key or certificate.
4107 * Implemented the GETKEY command to the server and to the
4108 client library and on user interface.
4110 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

4122 the number of the SKE group that is used with PFS in re-key.
4123 Affected file silcd/idlist.h.
4125 * Added PFS re-key support to the server. Affected file is
4128 * Added silc_protocol_cancel to cancel execution of the next
4129 state of the protocol. Affected file is
4130 lib/silccore/silcprotocol.[ch].
4132 * Added the re-key support with and without PFS to the client
4133 library. Re-key is performed once in an hour, by default.
4135 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4136 Added silc_client_rekey_callback and silc_client_rekey_final.
4137 Affected files are lib/silcclient/protocol.[ch] and

4142 lib/silcclient/client.h.
4146 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4148 * Do not ask whether user wants to use the negotiated private key
4149 for private messages, just use it. Affected file is
4150 silc/local_command.c.
4152 * Added `send_enc_key' and `enc_key_len' fields to the
4153 SilcIDListData structure since they are needed in the re-key
4154 phase. Affected file is silcd/idlist.[ch].

4168 the PFS is to be performed in the re-key. Affected file is
4171 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4173 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4174 int64 of at least the xintXX size. If void * is less that 4
4175 bytes uint32 * will be used. Defined bool as boolean.
4177 * Changed _ALL_ unsigned long and unsigned int to uint32,
4178 unsgined short to uint16 in the source tree.
4180 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4181 not handle clients that has entry->data.registered == FALSE.
4182 They are not in the network anymore. Affected file is
4185 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4187 * Implemented the sending of the SERVER_SIGNOFF notify in the
4188 server. Affected file is silcd/server.c.
4190 * Added silc_server_send_notify_args into silcd/packet_send.[ch].

4195 Affected file silcd/packet_receive.c.
4197 * Implemented the SERVER_SIGNOFF notify handling in the client
4198 library. Affected file lib/silcclient/client_notify.c. Also,
4199 implemnted the printing of the SERVER_SIGNOFF info to the
4200 application. Affected file silc/client_ops.c.
4202 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4203 if the deleting was successful. Affected file silcd/idlist.[ch].
4205 * Added support for public key authentication in the connection
4206 authentication protocol in the client library. Affected file
4207 lib/silcclient/protocol.c.
4209 * Changed the server's silc_idlist_get_clients_by_* interface
4210 to support already allocated array so that new entries may be
4211 added to pre-allocated array. Affected file silcd/idlist.[ch].
4212 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4213 and command replies.
4215 * All command reply functions in the server now calls the
4216 pending command callback even if error occured. This way the
4217 error will be delivered to the client as well. Affected files
4218 silcd/command.c and silcd/command_reply.c.
4220 * Fixed INFO command to return local server's info if no server
4221 was provided. Affected file lib/silcclient/command.c.
4223 * Removed RESTART command for good. Updated the code and the
4226 * Rewrote parts of the task system. It is a bit simpler now.
4227 Removed unsued task priorities. The affected files are
4228 lib/silcutil/silctask.[ch].
4230 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4232 * Moved the USERS printing from the library to the application.
4233 Affected files lib/silcclient/command.c and silc/client_ops.c.
4235 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4239 * Added channel key re-key support. The re-key is perfomed
4240 only by the router and is done once in an hour. Added `rekey'
4241 field to the SilcChannelEntry in the server. Affected files
4242 silcd/server.c and silcd/idlist.h.
4244 * Added silc_task_unregister_by_context into the file
4245 lib/silcutil/silctask.[ch].

4249 * Added SILC_UMODE_GONE mode to indicate when the client is not
4250 present in the SILC network. Added also support to the local
4251 command AWAY that will set this mode. Added support of showing
4252 "xxx is gone" in WHOIS command. The USERS command shows the
4253 gone status as well.
4255 * Fixed setting server and router operator privileges in the
4256 server's UMODE command. Affected file silcd/command.c.
4258 * Merged the SKE KE1 and KE2 payloads into one payload. The
4259 new KE payload is equivalent to the old KE2 payload.
4261 Cleaned up the SKE Start Payload parsing. It now uses the
4262 simple buffer unformatting to do the parsing. A lot faster
4265 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4266 to the SKE that is used to indicate whether both of the SKE
4267 parties should perform authentication. By default only the
4268 responder performs authentication. By setting this flag also
4269 the initiator must do authentication. By default it is unset
4270 since in normal SKE case, client to server connection, only
4271 the responder should do authentication. When doing SKE between
4272 two clients both should perform authentication. Updated the
4273 code and the protocol specs.
4275 * A little fix to IDENTIFY command in the server. Search the
4276 client first by hash not nickname. Affected file is
4279 * Fixed the silc_client_close_connection to support closing
4280 the client to client connections wihtout deleting too much
4281 data. Affected file lib/silcclient/client.c.
4283 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4284 are received if protocol used to be active but is not anymore
4285 the application would crash due to NULL pointer dereference.
4286 Affected files silcd/server.c and lib/silcclient/client.c.
4288 * Added `hash' field to the SilcClientConnection to include
4289 the hash function negotiated in the SKE protocol.
4291 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4292 to set the channel founder authentication data. A client can
4293 claim the founder rights later by providing the authentication
4294 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4295 This way the channel founder can regain the channel founder
4296 privileges even it is left the channel. This works only on
4297 local server and the client must be connected to the same
4298 server to be able to regain the founder rights. Updated the
4299 protocol specs accordingly.
4301 Added support to the CMODE command in the client to set the
4302 founder auth data. Read the README to see how to set it.
4304 Added support to the CUMODE command to claim the founder
4305 rights. Read the README to see how to do it.
4307 Added support for the founder authentication to the Channel
4308 Entry in the server. Affected file silcd/idlist.h.
4310 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4311 server's CMODE command. Affected file silcd/command.c.
4313 * Added the following new functions into lib/silccore/silcauth.[ch]:
4314 silc_auth_get_method and silc_auth_get_data.
4316 * The server now saves the remote hosts public key to the
4317 SilcIDListData pointer. Affected file silcd/protocol.c.
4319 * The normal server now does not remove the channel entry from
4320 the cache if the founder authentication data is set. It used
4321 to remove it if the founder was the last one on the channel on
4322 the server and left the channel. The auth data is saved and
4323 if the channel is re-joined later the old entry is used with
4324 the old auth data. Affected files silcd/command_reply.c and
4327 * Removed the `pkcs' field from the SilcIDListData structure
4328 in the server; it is not used. Affected file silcd/idlist.h.
4330 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4332 * Fixed packet processing on slow links. Partial packets were
4333 never re-processed because the incoming data buffer was cleared
4334 by the application. Application must not directly clear the
4335 sock->inbuf, the packet processing routines handle it. Fixed
4336 this in client library and in server.
4338 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4340 * Fixed the WHOIS and IDENTIFY send reply function to really
4341 check whether to send list or just one entry. Affected file
4344 * Cleaned up the LEAVE command's channel key distribution. The
4345 affected file silcd/command.c.
4347 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4348 can enforce the channel mode as well. In that case the ID
4349 includes the ID of the server. The code now enforces the
4350 mode change if the router have different mode than the server.
4352 * The notify client operation with CMODE_CHANGE notify can now
4353 return NULL client_entry pointer if the CMODE was not changed
4354 by client. Application must check for this.
4356 * Added <Server ID> argument to INFO command to support server
4357 info fetching by Server ID.
4359 * Added silc_server_announce_get_channel_users to get assembled
4360 packets of channel users of the specified channel. Affected
4361 file silcd/server.[ch].
4363 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4364 was freed underneath the ID Cache.
4366 * Re-announce clients when the server received CHANNEL_CHANGE
4367 notify from the router. Affected file silcd/packet_send.c.
4369 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4371 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4372 crashed since it did not handle the fact that there is no cipher
4373 called "3" and didn't check the error condition. Now fixed.
4375 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4376 flag. It can be used to send message requests.
4378 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4380 * Implemented the RESTART command in the client.
4382 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4383 notice type messages. Added notice printing to the user
4386 * The channel keys are not re-generated if the channel's mode
4387 is PRIVKEY, ie private key on the channel exists. Affected
4388 files silcd/server.c and silcd/command.c.
4390 * Fixed a little bug in channel message delivery when channel
4391 private keys are set in the server. Affected file is
4392 silcd/packet_send.c.
4394 * Changed the setting on channel->on_channel = TRUE from the
4395 silc_client_save_channel_key to the JOIN command reply. The
4396 key payload is not received if the private channel key is set.
4397 Affected file lib/silcclient/command_reply.c and the
4398 lib/silcclient/client_channel.c.
4400 * When the CMODE_CHANGE notify is sent and the channel private
4401 key mode is removed the channel key must be re-generated in
4402 other cells as well. Added this support for the router in the
4403 silcd/packet_receive.c.
4405 * Added new local command NOTICE to send notice message on
4406 channel. Affected file silc/local_command.[ch].
4408 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Added new local command ME to the client. It is used to send
4411 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4412 some action. Affected file silc/local_command.[ch].
4414 * Changed channel_message and private_message client operations
4415 to deliver the message flags to the application. Added also
4416 the `flags' arguments to the silc_client_send_channel_message
4417 and silc_client_send_private_message functions. Affected file
4420 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Redefined the Private Message Payload to support private message
4423 keys and to support the new private message flags. Updated
4424 the protocol specs. Flags makes it possible to have for example
4425 CTCP style messages.
4427 * Added new type SilcPrivateMessagePayload and defined an API
4428 for it in the lib/silcclient/silcprivate.[ch].
4430 * Tested private message private keys successfully. Tested the
4431 private message key set, unset and list commands with the new
4434 * Redefined the Channel Message Payload to include the channel
4435 message flags (equal with private message flags) to support
4436 for example CTCP style messages.
4438 * Defined some of the message (for channel and private message)
4439 flags. Updated the protocol specs and added the flags to the
4440 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4442 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4444 * Added SilcKeyAgreementStatus type to the key agreement routines
4445 to indicate the current status and error if one occured.
4446 The status types are defined in the lib/silcclient/silcapi.h.
4448 * Added new local command KEY that is used to set and unset private
4449 keys for channels, set and unset private keys for private messages
4450 with remote clients and to send key agreement requests and
4451 negotiate the key agreement protocol with remote client. The
4452 key agreement is supported only to negotiate private message keys,
4453 it currently cannot be used to negotiate private keys for channels,
4454 as it is not convenient for that purpose.
4456 * Fixed a minor pending callback setting bug in the function
4457 silc_client_get_client_by_id_resolve, now the function works.
4458 Affected file lib/silcclient/idlist.c.
4460 * Added function silc_net_get_local_port to get local bound
4461 port by socket. Added to lib/silcutil/silcnet.[ch].
4463 * Added `sockets' and `sockets_count' fields to the SilcClient
4464 object. They hold the sockets of the listenning sockets in
4465 the client. Listenning sockets may be for example the key
4466 agreement server. Affected file lib/silcclient/client.[ch].
4467 Added functions the silc_client_add_socket and the
4468 silc_client_del_socket. They are exported to the application
4471 * Added ~./silc/clientkeys to support other client's public keys.
4473 * Renamed verify_server_key client operation to verify_public_key
4474 and added one argument to indicate the type of the connection
4475 (server, client etc.).
4477 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4479 * Added silc_server_connection_auth_request to handle the
4480 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4481 silcd/packet_receive.[ch].
4483 * Added silc_server_send_connection_auth_request into the
4484 silcd/packet_send.c to send the connection auth request packet.
4486 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4489 * Fixed the public key authentication in responder side in the
4490 server. The `auth_data' pointer includes the SilcPublicKey
4491 not the path to the public key. Affected file silcd/protocol.c.
4493 * Implemented the public key authentication in the initiator side
4494 in the server. Affected file silcd/protocol.c.
4496 * Removed the [RedirectClient] config section from the server
4497 configuration. Is not needed and I don't want to implement it.
4499 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4501 * Cleaned up the CMODE command in the server. It now works
4502 correctly and supports all the modes defined in the protocol.
4503 Affected file is silcd/command.c.
4505 * Added `hmac_name' field to the SilcChannelEntry in the server
4506 to hold the default HMAC of the channel. It can be set when
4507 creating the channel (with JOIN command). Affected files
4510 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4511 type to indicate the change of the current cipher and hmac
4512 on the channel. Client can safely ignore the <cipher> argument
4513 (if it chooses to do so) since the CHANNEL_KEY packet will
4514 force the channel key change anyway. The <hmac> argument is
4515 important since the client is responsible of setting the new
4516 HMAC and the hmac key into use.
4518 * Fixed the CMODE command in the client library as well.
4520 * Tested CMODE command in router environment successfully.
4522 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * Show the version of the remote client (or server) when connecting
4525 to the server. It is logged to the log file. Affected file
4526 is silcd/protocol.c.
4528 * Fixed the KILLED notify handling in the client library. The
4529 client must be removed from all channels when receiving the
4532 Also, do not remove the client entry when giving the KILL
4533 command but when the KILLED notify is received.
4535 * Removed silc_idlist_find_client_by_nickname from the server.
4536 Not needed anymore. Affected files silcd/idlist.[ch].
4538 * Implemented the CHANNEL_CHANGE notify type handling to the
4539 server. Affected file silcd/server.c.
4543 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4545 * Added silc_server_send_notify_invite to send the INVITE
4546 notify between routers.
4548 * Implemented the INVITE command correctly to the server.
4550 * Implemented the INVITE notify type handling in the server.
4552 * Implemented the INVITE command to the client library and on the
4555 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4557 * Added function silc_server_get_client_resolve to find the
4558 client entry by ID from all ID lists and then resolve it
4559 (using WHOIS) if it cannot be found. Affected file is
4562 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4564 * Implemented the BAN command to the client library.
4566 * The JOIN command in the server now checks the invite list
4569 * Changed the silc_command_reply_payload_encode_va and the
4570 silc_command_payload_encode_va to support that if argument is
4571 NULL it ignores and checks the next argument. Affected file
4572 lib/silccore/silccommand.c.
4574 * Added silc_server_send_notify_ban to send the BAN notify
4575 type between routers.
4577 * Chaned the silc_notify_payload_encode to support that if
4578 argument is NULL it ignores and checks the next argument.
4579 Affected file lib/silccore/silcnotify.c.
4581 * Tested ban lists in router environment successfully.
4583 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * Implemented BAN command to the server, in silcd/command.[ch].
4587 * Removed the BAN and INVITE_LIST modes from the CMODE command
4590 * Added function silc_string_match to regex match two strings.
4591 Affected files lib/silcutil/silcutil.[ch].
4593 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4595 * Redefined parts of the SilcChannelEntry in the server to support
4596 the new ban and invite lists.
4598 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Redefined the INVITE command. The same command can be used to
4601 invite individuals to the channel but also to manage the invite
4602 list of the channel (to add to and remove from the invite list).
4603 Updated the protocol specs.
4605 * Added new command SILC_COMMAND_BAN that can be used to manage
4606 the ban list of the channel. Updated the protocol specs.
4608 * Removed the channel modes: the SILC_CMODE_BAN and the
4609 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4610 in the CMODE command. The equivalent features are now available
4611 using INVITE and BAN commands. Updated the protocol specs.
4613 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4614 in the network about change in the current ban list. The notify
4615 type is not used by the client.
4617 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4618 support the invite lists.
4620 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Added new function silc_string_regexify that converts string
4623 including wildcard characters into regex string that can
4624 be used by the GNU regex library. Added into the file
4625 lib/silcutil/silcutil.[ch].
4627 Added silc_string_regex_combine to combine to regex strings
4628 into one so that they can be used as one regex string by
4629 the GNU regex library. Added into the file
4630 lib/silcutil/silcutil.[ch].
4632 Added silc_string_regex_match to match two strings. It returns
4633 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4635 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4637 * Imported GNU regex to the soruce tree into lib/contrib.
4638 Fixed some compiler warning from the regex.c.
4640 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * Fixed MOTD command in the server to work in router environment.
4644 * Fixed the MOTD command in the client library to support
4645 the server argument in the command.
4647 * Added `nickname_len' argument to the silc_idlist_add_client
4648 in the server, as the `nickname' argument may be binary data
4651 * Added silc_idlist_get_channels to return all channels from
4654 * Implemented LIST command to the server. Affected file is
4657 * Implemented the LIST command to the client library and on the
4660 * Added [<user count>] argument to the LIST command reply.
4661 With private channels the user count is not shown.
4663 * Updated TODO and README.
4665 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4667 * The client entry's data.registered must be TRUE even with
4668 global client entry on global client list. The data.registered
4669 is used to check whether the client is anymore in the network,
4670 for example with WHOWAS command so it must be valid.
4672 * Fixed the WHOWAS command in the server. It now actually works
4673 in router environment. Added function into silcd/command_reply.c
4674 silc_server_command_reply_whowas_save.
4676 * Added silc_idlist_purge function to the silcd/idlist.c
4677 to periodically purge the ID Cache.
4679 * Fixed INFO command in the server. It works now in router
4680 environment. Added <server name> argument to the INFO command
4681 reply. Updated the protocol specs.
4683 * Fixed minor bug in silc_idcache_purge to not purge if the
4684 expire value is zero.
4686 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4687 they were buggy because of the WHOWAS information.
4689 * Fixed local command MSG to handle the async resolving of
4690 the remote client properly. It used to fail the first MSG.
4691 Affected file silc/local_command.c.
4693 * Added `data_len' field to SilcIDCache context.
4695 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4697 * Update TODO. Todo in commands in the server.
4699 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4701 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4702 used by routers as broadcast packet to inform other routers
4703 about the changed user mode.
4705 Implemented the notify handling in the server. Affected file is
4706 silcd/packet_receive.c. Added the function
4707 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4709 * Added new generic Channel Payload and deprecated the New Channel
4710 Payload. The New Channel Payload is now the generic Channel
4713 * Added new argument `mode' to the silc_server_send_new_channel
4714 as it is required in the Channel Payload now.
4716 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4717 and created a new and real SilChannelPayload to represent the
4718 new generic Channel Payload. Implemented the encode/decode
4719 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4721 * Added silc_server_get_client_channel_list to return the list
4722 of channels the client has joined for WHOIS command reply.
4723 Affected file silcd/server.[ch].
4725 * Implemented the channel list sending in the WHOIS command reply
4726 in server and in the client.
4728 Implemented the channel list displaying on the user interface
4729 as well. Affected file silc/client_ops.c.
4731 * Added silc_channel_payload_parse_list to parse list of Channel
4732 Payloads. It returns SilcDList list of SilcChannelPayloads.
4733 Client for example can use this function to parse the list of
4734 channels it receives in the WHOIS command reply. The caller
4735 must free the list by calling silc_channel_payload_list_free.
4736 Affected files lib/silccore/silcchannel.[ch].
4738 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Added one new argument <user mode> to the WHOIS command reply
4741 to return the mode of the user in SILC. Updated the protocol
4744 Implemented it to the server and client.
4746 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4748 * Fixed the mode printing on the user interface on joining.
4749 Affected file silc/client_ops.c.
4751 * Implemented the UMODE command and user modes in general to the
4752 client library and to the user interface.
4754 * Implemented the UMODE command to the server.
4756 * The server now sends UNKNOWN_COMMAND error status if client sends
4757 unknown command. Affected file silcd/command.c.
4759 * All server commands now handle the command identifier the right
4760 way when sending the command reply to the client. The client can
4761 use to identify the command replies with the identifier.
4763 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4765 * Added silc_server_get_client_route to resolve the route to
4766 the client indicated by the client ID. Affected file is
4769 * Added silc_server_relay_packet as general function to relay
4770 packet to arbitrary destination. This deprecates functions
4771 like _send_private_message_key, _relay_notify etc. Affected
4772 file is silcd/packet_send.[ch].
4774 Removed silc_server_send_key_agreement,
4775 silc_server_send_private_message_key and
4776 silc_server_packet_relay_notify functions from the file
4777 silcd/packet_send.[ch].
4781 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4782 server. Affected file silcd/packet_receive.[ch].
4784 * Implemented the KILL command to the client. Implemented the
4785 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4786 Affected files lib/silcclient/command[_reply].c and
4787 lib/silcclient/client_notify.c. Implemented the KILL notify
4788 printing in the user inteface.
4790 * Fixed a lot silc_parse_nick memory leaks from the client
4791 library in the file lib/silcclient/command.c.
4793 * Changed the silc_server_send_notify_on_channels's `sender'
4794 argument from SilcSocketConnection to SilcClientEntry to
4795 check the sender as entry and not as connection object and not
4796 to send to the client provided as argument. The affected file
4797 is silcd/packet_send.[ch].
4799 * The notify packets that are destined directly to the client used
4800 to not to be processed by the server. Now changed that and the
4801 server processes all notify packets. After relaying the packet
4802 to the client the notify packet is processed in the server.
4804 * The silc_server_free_client_data now checks whether there is
4805 pending outgoing traffic for the client and purges the data to
4806 the network before removing the client entry.
4808 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4810 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4811 an client is killed from the SILC Network. Updated the protocol
4814 Added new function silc_server_send_notify_killed to the
4815 silcd/packet_send.[ch].
4817 * Added function silc_server_packet_relay_notify to relay notify
4818 packets that are destined directly to a client. In this case
4819 the server does not process the notify packets but merely relays
4820 it to the client. Affected file silcd/packet_send.[ch].
4822 Added also silc_server_packet_process_relay_notify to check
4823 whereto relay the notify. Affected file is
4824 silcd/packet_receive.[ch].
4826 * Implemented the KILL command to the server.
4830 * Added the backup schema desgined last fall to the protocol
4831 specs for everyone to see. The specification is in the
4832 *-spec-xx.txt draft and the packet type definitions for the
4833 backup routers is in *-pp-xx.txt draft. Thusly, added also
4834 new packet type SILC_PACKET_CELL_ROUTERS.
4836 * A big security problem in the implementation discovered. The
4837 signoff of an client did not cause new channel key generation
4838 which it of course should've done. The channel keys must be
4839 always re-generated when client leaves (or signoffs) the channel.
4840 The silc_server_remove_from_channels funtion now handles
4841 the channel key re-generation.
4843 * Added `sender' argument to the silc_server_send_notify_on_channels
4844 to not to send the client provided as argument. Affected file
4845 silcd/packet_send.[ch].
4847 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4849 * Implemented OPER and SILCOPER commands into the server and
4852 * Added silc_auth_verify and silc_auth_verify_data to verify
4853 the authentication directly from the authentication payload.
4854 It supports verifying both passphrase and public key based
4855 authentication. Affected file lib/silccore/silcauth.[ch].
4857 * Added `hash' field to the SilcIDListData structure. It is the
4858 hash negotiated in the SKE protocol. Affected file is
4861 * Slight redesigning of the SilcAuthPayload handling routines.
4862 Do not send SilcPKCS but SilcPublicKey as argument.
4864 * Implemented the public key authentication support to the
4865 serverconfig. The public key is loaded from the provided path
4866 and saved as authentication data to void * pointer. Thus,
4867 changed the unsigned char *auth_data to void *auth_data;
4869 * Fixed SHUTDOWN command to send the reply before the server
4870 is shutdown. :) Affected file silcd/command.c.
4872 * Fixed fatal bug in CONNECT command. The hostname was invalid
4873 memory and server crashed. Affected file silcd/command.c.
4875 * Fixed fatal bug in CLOSE command. The server_entry became
4876 invalid but was referenced later in the command. Affected file
4879 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4881 * Fixed fatal bug in failure packet handling. Server ignored
4882 the failure and thus crashed when it came.
4886 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4888 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4889 that the command may be executed only once in (about) 2 seconds.
4890 The old SILC_CF_LAG flag is same but allows command bursts up
4891 to five before limiting.
4893 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4894 server code. Various commands now includes the CF_LAG_STRICT
4895 flag to disallow any kind of miss-use of the command.
4897 * Fixed the silc_buffer_unformat to not to allocate any data
4898 if the length of the data is zero. It used to allocate the
4899 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4901 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4903 * Changed the format of AdminConnection configuration section
4904 in the server. Added username of the admin to the format.
4905 Affected files silcd/serverconfig.[ch].
4907 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4908 to return admin configuration data by host, username and/or
4911 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4913 * Implemented WHOWAS command to the server. Added the functions:
4915 silc_server_command_whowas_parse,
4916 silc_server_command_whowas_send_reply,
4917 silc_server_command_whowas_from_client and
4918 silc_server_command_whowas_from_server
4920 * Added <Client ID> argument to the WHOWAS command reply. Updated
4921 the protocol specs accordingly.
4923 * Implemented WHOWAS command and command_reply to the client
4926 Implemented the WHOWAS printing on the user interface.
4928 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4930 * Added new argument to the WHOWAS command reply, the real name.
4931 It is an optional argument. Updated the protocol specs.
4933 * Added SilcIDCacheDestructor callback that is registered when
4934 the SilcIDCache is allocated. The callback is called when
4935 an cache entry in the ID Cache expires, or is purged from the
4936 cache. Added into lib/silccore/idcache.[ch].
4938 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4939 to destruct the client entries when the cache entry expires.
4940 Other ID Cache's in server and in the client library ignores
4943 * If the ID Cache entry's `expire' field is zero then the entry
4944 never expires. Added boolean `expire' argument to the
4945 silc_idcache_add function in the lib/silccore/idcache.[ch].
4946 If it is TRUE the default expiry value is used.
4948 * Added silc_server_free_client_data_timeout that is registered
4949 when client disconnects. By default for 5 minutes we preserve
4950 the client entry for history - for WHOWAS command.
4952 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4954 * Added support to the server to enforce that commands are not
4955 executed more than once in 2 seconds. If server receives
4956 commands from client more frequently, timeout is registered
4957 to process the commands. Affected file silcd/command.c.
4958 Added new function silc_server_command_process_timeout.
4960 * Changed NICK_NOTIFY handling in client library to check that
4961 if the client's nickname was changed, so there is no need to
4962 resolve anything from the server.
4964 * Removed error printing from the WHOIS and IDENTIFY commands.
4965 If error occurs then it is ignored silently in the client library.
4966 The application, however, may map the received error to
4967 human readable error string. The application currently maps
4968 the NO_SUCH_NICKNAME error to string.
4970 * Made the command status message public to the application. Moved
4971 them from lib/silcclient/command_reply.c to
4972 lib/silcclient/command_reply.h. The application can map the
4973 received command status to the string with the
4974 silc_client_command_status_message function.
4976 * Added check to the server to check that client's ID is same
4977 as the Source ID in the packet the client sent. They must
4980 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4982 * Added dist-bzip hook to the Makefile.am to make bzip2
4983 compressed distributions.
4985 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4987 * Server now enforces the maximum length for the nickname and
4988 the channel as protocol specification dictates. 128 bytes for
4989 nickname and 256 bytes for channel name.
4991 * Moved the WHOIS printing to the application. The client libary
4992 does not print out the WHOIS information anymore, the application
4993 must do it. Renamed silc_client_command_reply_whois_print to
4994 the silc_client_command_reply_whois_save.
4996 The client's idle time is also sent to the application now, and
4997 the idle is shown on screen.
4999 * Added silc_client_command_reply_identify_save to save the
5000 received IDENTIFY entries.
5002 * Do not check for channel private keys in message sending and
5003 reception if the channel does not have the PRIVKEY mode set.
5004 Affected file lib/silclient/client_channel.c.
5006 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5008 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5009 just surfaced after chaning the JOIN procedure.
5011 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5013 * Added silc_client_get_clients_by_list to get client entries
5014 from Client ID list, that is returned for example by JOIN
5015 and USERS command replies. The application should use this
5016 function for example when JOIN command reply is received to
5017 resolve the clients already on the channel (library does not
5018 do that anymore as USERS command reply is not used in the JOIN
5019 procedure anymore). Affected files lib/silcclient/silcapi.h and
5020 lib/silcclient/idlist.c.
5022 * JOIN command reply and USERS command reply returns now SilcBuffer
5023 pointers instead of unsigned char pointers when returning
5024 the client list and mode list.
5026 * Added <Client ID> argument to the JOIN command reply, mainly
5027 for the server to identify for which client the command was
5028 originally sent. Updated protocol specs accordingly.
5030 * Added SilcDlist private_key pointer to the SilcChannelEntry
5031 in the client to support the channel private keys. Affected
5032 file is lib/silcclient/idlist.h.
5034 * Added SilcChannelPrivateKey argument to the function
5035 silc_client_send_channel_message so that application can choose
5036 to use specific private ke if it wants to. If it is not provided,
5037 the normal channel key is used, unless private keys are set.
5038 In this case the first (key that was added first) is used
5039 as the encryption key.
5041 * Implemented the support for channel private key handling.
5042 Implemented the following functions:
5044 silc_client_add_channel_private_key,
5045 silc_client_del_channel_private_keys,
5046 silc_client_del_channel_private_key,
5047 silc_client_list_channel_private_keys and
5048 silc_client_free_channel_private_keys
5050 Affected file lib/silcclient/client_channel.c.
5052 * Added the support for the private keys in the channel message
5053 sending and encryption and in the message reception and
5054 decryption. Affected funtions are
5055 silc_client_send_channel_message and silc_client_channel_message.
5057 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5059 * Added SKE's key verify callback to the client library's
5060 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5062 * Removed the statement that server (or router) must send USERS
5063 command reply when joining to the channel so that the client
5064 knows who are on the channel. Instead, the client list and
5065 client's mode list is now sent in the JOIN command reply to the
5066 client who joined channel. This is better solution.
5068 * Added function silc_server_get_users_on_channel and function
5069 silc_server_save_users_on_channel to the silcd/server.[ch].
5071 * Removed function silc_server_command_send_users from the
5074 * Do not show topic on the client library anymore. The topic is
5075 sent in the command reply notify to the application and the
5076 application must show the topic now.
5078 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5080 * Added client searching by nickname hash into the IDENTIFY and
5081 WHOIS commands in the server as they were clearly missing from
5082 them. Affected file is silcd/command.c.
5084 * Fixed a bug in private message receiving in the client library.
5085 The remote ID was freed and it wasn't supposed, now it is
5088 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5090 * Minor fix to the channel payload; allocate the data area, as it
5091 needs to be of specific length.
5093 * If the key agreement port is zero then the operating
5094 system will define the bound port. Affected files are
5095 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5097 * Added new function silc_channel_payload_decrypt into the file
5098 lib/silccore/silcchannel.[ch].
5100 * Moved the channel message etc, check from silc_packet_decrypt
5101 to applications. The library calls now a generic
5102 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5103 when the packet is either normal or special. This was done to
5104 allow more wide range of checking that was not allowed when
5105 the code was in library. Now applications can do virtually any
5106 checks to the packet and return to the library the decision how
5107 the packet should be processed. Affected files are
5108 lib/silccore/silcpacket.[ch].
5110 Added silc_server_packet_decrypt_check to the server and
5111 silc_client_packet_decrypt_check to the client library.
5113 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5114 to send with specified source and destination information.
5116 * Channel message delivery between routers was broken after the
5117 channel key distribution was fixed earlier. The channel key
5118 was used be to distributed to other routers as well which is not
5119 allowed by the protocol. Now this is fixed and channel keys
5120 really are cell specific and the channel message delivery between
5121 routers comply with the protocol specification.
5123 * Fixed various commands in server to check also the global list
5124 for the channel entry and not just the local list. The affected
5125 file silcd/command.c.
5127 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5129 * Added assert()s to buffer formatting and unformatting routines
5130 to assert (if --enable-debug) when error occurs. Affected
5131 file: lib/silcutil/silcbuffmt.c.
5133 * Changed to auto-reconnect to check whether the remote host is
5134 router and register the re-connect timeout if it is. It used
5135 to check that whether we are normal server, but router must do
5136 auto-reconnect with another router as well. Affected file
5139 * Removed the [<key len>] option from CMODE command as the cipher
5140 name decides the key length, nowadays. See the defined ciphers
5141 from the protocol specification.
5143 * Added [<hmac>] option to the CMODE command to define the HMAC
5144 for the channel. Added SILC_CMODE_HMAC channel mode.
5146 * Added [<hmac>] option for the JOIN command so that user can
5147 select which HMAC is used to compute the MACs of the channel
5150 * Added Hmac field to the Channel Message Payload. The integrity
5151 of plaintext channel messages are now protected by computing
5152 MAC of the message and attaching the MAC to the payload. The
5153 MAC is encrypted. Now, it is clear that this causes some
5154 overhead to the size of the packet but rationale for this is that
5155 now the receiver can verify whether the channel message decrypted
5156 correctly and also when private keys are set for the channel the
5157 receiver can decrypt the packet with several keys and check from
5158 the MAC which key decrypted the message correctly.
5160 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5161 lib/silccrypt/silccipher.[ch].
5163 * Added silc_hash_len to return the digest length into the
5164 lib/silcrypt/silchash.[ch].
5166 * Rewrote parts of Silc Channel Payload interface in the
5167 lib/silccore/silcchannel.[ch]. The encode function now also
5168 encrypts the packet and parse function decrypts it.
5170 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5172 * Fixed a minor formatting bug in the SKE's key material processing.
5173 It actually might have processed the keys wrong way resulting
5176 * Redefined the mandatory HMAC algorithms and added new algorithms.
5177 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5178 and hmac-md5 truncated to 96 bits. The mandatory is now
5179 hmac-sha1-96. Rest are optional (including the one that used
5180 to be mandatory). Rationale for this is that the truncated HMAC
5181 length is sufficient from security point of view and can actually
5182 make the attack against the HMAC harder. Also, the truncated
5183 HMAC causes less overhead to the packets. See the RFC2104 for
5186 * Added new [hmac] configuration section. The SKE used to use
5187 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5188 is of course wrong. The official names that must be proposed in
5189 the SKE are the ones defined in the protocol specification
5190 (hmac-sha1-96 for example). The user can configure any hmac
5191 using any hash function configured in the [hash] section. At
5192 least, the mandatory must be configured.
5194 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5196 * Added HMAC list to the SKE proposal list. It has now both
5197 hash algorithm list and HMAC list. This makes the protocol
5198 incompatible with previous versions. The SKE now seems to work
5199 the way it is supposed to work, for the first time actually.
5201 * Defined plain Hash algorithms to the protocol specification.
5204 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5206 * Implemented support for key agreement packets into the server.
5207 Added functions silc_server_key_agreement and
5208 silc_server_send_key_agreement. Other than these functions,
5209 server has nothing to do with this packet.
5211 * Added support for private message key packets into the server.
5212 Added functions silc_server_private_message_key and
5213 silc_server_send_private_message_key.
5217 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5218 called in the protocol's final callback instead in the END
5219 protocol state. This makes a little more sense and in the same
5220 time in client we can use the same protocol routines for normal
5221 key exchange and to key agreement packet handling as well.
5223 * Added to both client's and server's KE protocol context the
5224 SilcSKEKeyMaterial pointer to save the key material. We will
5225 bring the key material to the protocol's final callback by doing
5226 this. The final callback must free the key material.
5228 * Added SKE's packet_send callback into client's KE protocol
5229 context so that the caller can choose what packet sending function
5230 is used. This way we can use different packet sending when
5231 doing normal SKE when doing key agreement packet handling (in
5232 the key agreement packet handling we do not want to encrypt
5235 * Implemented the responder side of the key agreement routines
5236 in the client. The client can now bind to specified port and
5237 accept incoming key negotiation. The key material is passed
5238 to the application after the protocol is over.
5240 * Implemented the processing of incoming Key Agreement packet
5241 in the client. Added function silc_client_key_agreement to
5244 * Implemented the intiator side of the key agreement routines
5245 in the client. The client can now initiate key agreement with
5246 another remote client. The key material is passed to the
5247 application after the protocol is over.
5249 * Created client_keyagr.c to include all the key agreement
5252 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5253 SILC_TASK_CALLBACK except that it is not static.
5255 * Created client_notify.c and moved the Notify packet handling
5256 from the client.[ch] into that file.
5258 * Created client_prvmsg.c and moved all private message and
5259 private message key routines from the client.[ch] into that file.
5261 * Create client_channel.c and moved all channel message and
5262 channel private key routines from the client.[ch] into that file.
5264 * Changed silc_client_get_client_by_id_resolve to resolve with
5265 WHOIS command instead of IDENTIFY command, in the file
5266 lib/silclient/idlist.c.
5268 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5270 * Implemented the SKE's responder side to the Client library.
5272 * When FAILURE is received to the protocol do not trust it
5273 blindly. Register a timeout to wait whether the remote closes
5274 the connection as it should do it, only after that process the
5275 actual failure. This was changed to both client and server.
5277 * Added client_internal.h to include some of the structures
5278 there instead of client.h in lib/silcclient/.
5280 * Added function silc_task_unregister_by_callback to unregister
5281 timeouts by the callback function.
5283 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5285 * Some "Incomplete WHOIS info" errors has been appearing on the
5286 log files. Took away the entry->userinfo check from WHOIS
5287 reply sending. The entry->userinfo is now " " if client did not
5288 provide one. I thought this was fixed earlier but something
5289 is wrong still. Let's see if the error still appears.
5291 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * Fixed a minor bug in the login when the channel key is
5294 re-generated in the server. It used to generate the key in
5295 wrong order and thus caused problems in the channel traffic.
5297 * Fixed a minor bug in channel key distsribution after
5298 KICK command. The key was not sent to the router even though
5301 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Added silc_ske_process_key_material_data as generic routine
5304 to process any key material as the SILC protocol dictates. The
5305 function is used by the actual SKE library but can be used by
5306 applications as well. This relates to the private message keys
5307 and the channel private keys since they must be processed the
5308 same way the normal SILC session keys. The protocol dictates
5309 this. Affected files: lib/silcske/silcske.[ch].
5311 Added also silc_ske_free_key_material to free the
5312 SilcSKEKeyMaterial structure.
5314 * Defined silc_cipher_set_key function to set the key for
5315 cipher without using the object's method function. The affected
5316 files: lib/silccrypt/silccipher.[ch].
5318 * Implemented silc silc_client_add_private_message_key,
5319 silc_client_add_private_message_key_ske,
5320 silc_client_del_private_message_key,
5321 silc_client_list_private_message_keys and
5322 silc_client_free_private_message_keys functions in the
5325 Added functions silc_client_send_private_message_key to send
5326 the Private Message Key payload and silc_client_private_message_key
5327 to handle incoming Private Message Key payload.
5329 * Added Cipher field to the Private Message Key payload to set
5330 the cipher to be used. If ignored, the default cipher defined
5331 in the SILC protocol (aes-256-cbc) is used.
5333 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5335 * Removed lib/silcclient/ops.h file.
5337 Redefined parts of the SILC Client Library API. Created new
5338 file silcapi.h that deprecates the ops.h file and defines the
5339 published Client Library API. Defined also private message key
5340 API and channel private key API into the file.
5342 This is the file that the application must include from the
5343 SILC Client Library. Other files need not be included by
5344 the application anymore.
5346 * Added new key_agreement client operation callback and also
5347 defined the Key Agreement library API for the application.
5349 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5351 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5352 is used by clients to request key negotiation between another
5353 client in the SILC network. If the negotiation is started it
5354 is performed using the SKE protocol. The result of the
5355 negotiation, the secret key material, can be used for example
5356 as private message key.
5358 Implemented the Key Agreement payload into the files
5359 lib/silccore/silauth.[ch].
5361 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5363 * Redefined ciphers for the SILC protocol. Added some new ciphers
5364 and defined the key lengths for the algorithms. Changed the
5365 code accordingly. The default key length is now 256 bits.
5367 * Fixed SKE key distribution function silc_ske_process_key_material
5368 when the key length is more than 128 bits. The default key
5369 length in SILC is now 256 bits.
5371 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5372 to indicate unsupported algorithm.
5374 * Renamed rijndael.c to aes.c and all functions as well.
5376 * Fixed a long standing channel key setting bug in client library.
5377 Weird that it has never surfaced before.
5379 * Fixed bug in channel deletion. If the entire channel is removed
5380 then it must also delete the references of the channel entry
5381 from the client's channel list as the client's channel entry and
5382 the channel's client entry share same memory.
5384 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5386 * Implemented CONNECT and SHUTDOWN commands in the client.
5388 * Implemented CLOSE command to the client.
5390 * Added the function silc_idlist_find_server_by_name into the
5391 files silcd/idlist.[ch].
5393 Added the function silc_idlist_find_server_by_conn into the
5394 files silcd/idlist.[ch].
5396 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5398 * DIE command was renamed to SHUTDOWN. Updated the both code
5401 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5402 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5404 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5407 * Added function silc_server_create_connection function to create
5408 connection to remote router. My server implementation actually
5409 does not allow router to connect to normal server (it expects
5410 that normal server always initiates the connection to the router)
5411 so the CONNECT command is only good for connecting to another
5414 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5417 or some other client was kicked from the channel.
5419 Implemented the handling of the notify type to both client
5422 Implemented silc_server_send_notify_kicked to send the KICKED
5423 notify. It is used to send it to the server's primary router.
5425 * Implemented the KICK command into server and client.
5427 * Added `query' argument to the silc_idlist_get_client function
5428 to indicate whether to query the client from server or not if
5431 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5432 to indicate that the client is not channel founder.
5436 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5438 * Removed the rng context from SilcPacketContext structure and
5439 changed that the packet routine uses the Global RNG API.
5441 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5443 * Added support for quit message that client can "leave" on the
5444 channel when it quits the SILC. It is ditributed inside the
5445 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5447 Added silc_server_free_client_data that will take the
5448 signoff message as argument.
5450 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5452 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5454 * Updated parts of the protocol specification to keep it up
5457 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5459 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5460 payloads in one packet.
5462 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5463 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5464 use now the new List flag.
5466 * Also deprecated the following packet types: REPLACE_ID,
5467 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5469 * Added list support for Notify packet in server.
5471 * Added silc_server_send_notify_channel_change to send the
5472 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5473 the silc_server_send_replace_id.
5475 * Added silc_server_send_notify_nick_change to send the
5476 NICK_CHANGE notify type. Deprecates the function
5477 silc_server_send_replace_id.
5479 * Added silc_server_send_notify_join to send the JOIN notify type.
5480 Deprecates the function silc_server_send_new_channel_user.
5482 * Added silc_server_send_notify_leave to send LEAVE notify type.
5483 Deprecates the function silc_server_send_remove_channel_user.
5485 * Added silc_server_send_notify_cmode and
5486 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5487 types. Deprecates the silc_server_send_set_mode function.
5489 * Added SERVER_SIGNOFF notify type to indicate that server has
5490 quit. This means that all clients on the channel from that
5491 server will drop. This can be also used when netsplit happens.
5493 Deprecated REMOVE_ID packet type since it is not needed anymore
5496 Added silc_server_send_notify_server_signoff to send the
5497 SERVER_SIGNOFF notify type. Deprecates the function
5498 silc_server_send_remove_id.
5500 Added also silc_server_send_notify_signoff to send the
5501 SIGNOFF notify type.
5503 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5504 SILC protocol from this day on. Changed the protocol
5505 specification as well.
5507 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5508 notify type. It is used between routers to notify about
5509 topic changes on a channel.
5511 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5514 * Partly updated the protocol specification to comply with the
5515 changes now made. It is still though a bit outdated.
5517 * The JOIN notify type now takes one extra argument <Channel ID>.
5518 The packet used to be destined to the channel but now the
5519 JOIN type may be sent as list thus it is impossible to
5520 destine it to any specific channel. By adding this argument
5521 it is again possible.
5523 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * Added CREDITS file. The CHANGES and CREDITS file will appear
5526 in the distribution as well.
5528 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5530 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5531 types in the server's silcd/packet_receive.c.
5533 * Implemented CMODE and CUMODE to work in router environment.
5535 * Fixed minor encoding and decoding buglet from the
5536 lib/silccore/silcmode.c.
5538 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5541 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5543 * Changed all SilcConfigServer* and silc_config_server* to
5544 SilcServerConfig* and silc_server_config*, respectively.
5547 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * Associated the ID (client or server ID) to the Authentication
5550 Payload to avoid any possibility of forging. Updated the
5551 protocol specification and the code accordingly.
5553 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5555 * The RSA key length is now save to the RsaKey context in the
5556 key generation process in lib/silccrypt/rsa.c. The key length
5557 is now used to figure out the maximum size of the block allowed
5558 to be encrypted/signed.
5560 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5561 is equivalent to the silc_mp_mp2bin but does not allocate any
5564 * Changed silc_mp_mp2bin API to take length argument. If it is
5565 non-zero then the buffer is allocated that large. If zero, then
5566 the size is approximated using silc_mp_sizeinbase, which however
5569 * Created Global RNG API which is global RNG that application can
5570 initialize. After initializing, any routine anywhere in the
5571 code (including library) can use RNG without allocating a new
5572 RNG object. This was done to allow this sort of use of the
5573 RNG in code that has no chance to allocate RNG object. All
5574 applications currently allocate this and many routines in the
5575 library use this. Affected file lib/silccrypt/silcrng.[ch].
5577 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5578 it to use the Global RNG API.
5580 * Defined Authentication Payload into protocol specification that
5581 is used during SILC session to authenticate entities. It is
5582 used for example by client to authenticate itself to the server
5583 to obtain server operator privileges.
5585 Implemented this payload into the lib/silccore/silcauth.[ch].
5586 Implemented also routines for public key based authentication
5587 as the new protocol specification dictates.
5589 Moved definitions of different authentication methods from
5590 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5592 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5593 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5594 silc_pkcs_verify_with_hash functions into the file
5595 lib/silccrypt/silcpkcs.[ch].
5597 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5599 * The client entry's userinfo pointer must be always valid.
5600 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5601 will fail since it requires the userinfo. Now, the userinfo
5602 is allocated as "" if actual userinfo does not exist. Actually,
5603 it must exist and it is totally Ok to drop client connections
5604 that does not announce the userinfo. However, we will make
5605 this workaround for now.
5607 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5608 to return the remote port by socket.
5610 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5612 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5613 SILC_SERVER_PENDING_EXEC and added an new macro
5614 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5615 data or when error occurs while processing the pending command.
5617 Added new argument `destructor' into silc_server_command_pending
5618 and to the SilcServerCommandPending object. This destructor is
5619 now called after calling the pending callback or if error occurs
5620 immediately. If error occurs the actual pending callback won't
5621 be called at all - only the destructor. The destructor may be
5622 NULL if destructor is not needed.
5624 All this applies for client library code as well. Similar
5625 changes were made there as well for the pending commands.
5627 In the client, the application must now allocate the
5628 SilcClientCommandContext with the silc_client_command_alloc
5631 * Added reference counter to the SilcServerCommandContext. Added
5632 function silc_server_command_alloc and silc_server_command_dup
5635 Same type of functions added to the client library for the same
5638 * Removed the cmd_ident from IDListData away since it is now
5639 global for all connections. It is the command identifier used
5640 in command sending and with pending commands. The affected file
5643 * Added reference counter to the SilcSocketConnection objecet to
5644 indicate the usage count of the object. The object won't be
5645 freed untill the reference counter hits zero. Currently only
5646 server uses this, and client ignores it. The client must be
5647 set to use this too later. The affected files are
5648 lib/silccore/silcsockconn.[ch]. Added also the function
5649 silc_socket_dup to increase the reference counter.
5651 This was mainly added because it is possible that the socket
5652 is removed underneath of pending command or other async
5653 operation. Now it won't be free'd and proper DISCONNECTING
5654 flags, etc. can be set to avoid sending data to connection that
5655 is not valid anymore.
5657 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5658 the connection. After that it sets SILC_SET_DISCONNECTED.
5659 It is, however, possible that the socket data is not still freed.
5660 The silc_server_packet_process now checks that data is not
5661 read or written to connection that is DISCONNECTED. The socket
5662 get's freed when the reference counter hits zero.
5664 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5666 * Changed the client operation API: channel_message operation's
5667 `sender' is now the client entry of the sender, not the nickname
5668 and the `channel' is the channel entry, not the channel name.
5670 In the private_message operation the `sender' is now also the
5671 client entry of the sender not the nickname.
5673 Affected file is lib/silcclient/ops.h and all applications
5674 using the client operations.
5676 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5678 * Moved the calling of ops->connect() from connect_to_server_final
5679 into receive_new_id functin since that is the point when the
5680 client is actually allowed to send traffic to network. The
5681 affected file is lib/silcclient/client.c.
5683 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5685 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5686 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5687 (if needs broadcasting) instead of broadcasting the packets one
5688 by one which would make a burst in the network traffic.
5690 * Added `broadcast' argument to the functions in silcd/server.[ch]
5691 silc_server_create_new_channel[_with_id] to indicate whether
5692 to send New Channel packet to primary router.
5694 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5696 * Added new function into the silcd/server.[ch] files:
5697 silc_server_create_new_channel_with_id to create new channel with
5698 already existing Channel ID.
5700 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5701 lib/silccore/silcpacket.h. This packet is used t send list of
5702 Set Mode payloads inside one packet. Server uses this to set
5703 the modes for the channels and clients on those channels, that it
5704 announced to the router when it connected to it. The protocol
5705 specification has been updated accordingly.
5707 * The silc_server_new_channel did not handle the packet coming
5708 from normal server as it normally does not send that. However,
5709 when it announces its channels it does send it. Implemented
5710 the support for that.
5712 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5713 into the file lib/silccore/id.h.
5715 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5717 * Fixed memory leaks in the functions silc_idlist_del_client,
5718 silc_idlist_del_channel and silc_idlist_del_server in the file
5719 silcd/idlist.c. All of those leaked like a sieve.
5721 * Fixed some small memory leaks in the client's function
5722 silc_client_notify_by_server.
5724 * Added functions into silcd/server.c: silc_server_announce_clients,
5725 silc_server_announce_channels and silc_server_announce_server.
5726 These functions are used by normal and router server to announce
5727 to its primary router about clients, channels and servers (when
5728 router) that we own. This is done after we've connected to the
5731 These functions effectively implements the following packet types:
5732 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5733 and SILC_PACKET_NEW_ID_LIST.
5735 * Added new functions into the silcd/packet_receive.[ch]:
5736 silc_server_new_id_list, silc_server_new_channel_list and
5737 silc_server_new_channel_user_list to handle the incoming
5738 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5740 * Added support of changing Channel ID in the function
5741 silc_server_replace_id. If the server that announces a channel
5742 to the router already exists in the router (with same name but
5743 with different Channel ID), router is responsible to send
5744 Replace ID packet to the server and force the server to change
5745 the Channel ID to the one router has.
5747 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5748 client that the Channel ID has been changed by the router. The
5749 normal server sends this to the client. Client must start using
5750 the new Channel ID as the channel's ID.
5752 Implemented handling of this new type into lib/silcclient/client.c
5753 into the function silc_client_notify_by_server.
5755 * Added new function silc_idlist_replace_channel_id into the files
5756 silcd/idlist.[ch] to replace the Channel ID.
5758 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5760 * Call silc_server_command_identify_check always when processing
5761 the IDENTIFY command in silcd/command.c
5763 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5765 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5766 send keepalive packets. The packet can be sent by clients,
5767 servers and routers.
5769 Added function silc_socket_set_heartbeat into the file
5770 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5771 If not set, the heartbeat is not performed. The actual
5772 heartbeat is implemented in the low level socket connection
5773 library. However, application is responsible of actually
5776 Added silc_server_send_heartbeat to send the actual heartbeat
5777 packet into silcd/packet_send.[ch]. Server now performs
5778 keepalive with all connections.
5780 * Added silc_task_get_first function into lib/silcutil/silctask.c
5781 to return the timeout task with shortest timeout. There was a bug
5782 in task unregistration that caused problems. TODO has been
5783 updated to include that task system must be rewritten.
5785 * The client library will now resolve the client information when
5786 receiving JOIN notify from server for client that we know but
5787 have incomplete information.
5789 * Rewrote parts of silc_server_remove_from_channels and
5790 silc_server_remove_from_one_channel as they did not remove the
5791 channel in some circumstances even though they should've.
5793 * Encryption problem encountered in server:
5795 The LEAVE command used to send the Channel Key packet to the
5796 router immediately after generating it. However, the code
5797 had earlier sent Remove Channel user packet but not immediately,
5798 ie. it was put to queue. The order of packets in the router
5799 was that Channel Key packet was first and Remove Channel User
5800 packet was second, even though they were encrypted in the
5801 reverse order. For this reason, MAC check failed. Now, this
5802 is fixed by not sending the Channel Key packet immediately but
5803 putting it to queue. However, this is more fundamental problem:
5804 packets that are in queue should actually not be encrypted
5805 because packets that are sent immediately gets encrypted
5806 actually with wrong IV (and thus MAC check fails). So, packets
5807 that are in queue should be encrypted when they are sent to
5808 the wire and not when they put to the queue.
5810 However, the problem is that the current system has not been
5811 designed to work that way. Instead, the packet is encrypted
5812 as soon as possible and left to the queue. The queue is then
5813 just purged into wire. There won't be any fixes for this
5814 any time soon. So, the current semantic for packet sending
5817 o If you send packet to remote host and do not force the send
5818 (the packet will be in queue) then all subsequent packets to the
5819 same remote host must also be put to the queue. Only after the
5820 queue has been purged is it safe again to force the packet
5823 o If you send all packets immediately then it safe to send
5824 any of subsequent packets through the queue, however, after
5825 the first packet is put to queue then any subsequent packets
5826 must also be put to the queue.
5828 Follow these rules and everything works fine.
5830 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5832 * Added new function silc_server_remove_clients_by_server to
5833 remove all client entries from ID list when the server connection
5834 is lost. In this case it is also important to invalidate all
5835 client entires as they hold the invalid server entry. This
5836 fixes fatal bug when server has lost connection and will reconnect
5839 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5841 * Made some sanity checks to silc_server_daemonise like to check
5842 whether the requested user and group actually exists.
5844 * Added sanity check to SKE's silc_ske_responder_finish to check
5845 that the public and private key actually is valid.
5847 * Invalidate the client's nickname when receiving Replace ID
5848 packet and the Client ID is being replaced. This means that the
5849 server will query the nickname if someone needs it (client)
5852 * Sort the ID Cache in client library when the ID Cache data
5853 has changed (needs sorting).
5855 * Do not allow for SILC client to create several connections to
5856 several servers. The client does not support windows right now
5857 and generating multiple connections causes weird behaviour.
5859 Irssi-silc client does support windows and can handle several
5860 connections without problems, see: www.irssi.org and SILC plugin.
5862 * Fixed some places where client was added to the IDList. The
5863 rule of thumb is following (in order to get everything right):
5864 If the client is directly connected local client then the
5865 `connection' argument must be set and `router' argument must be
5866 NULL to silc_idlist_add_client function. If the client is not
5867 directly connected client then the `router' argument must
5868 bet set and the `connection' argument must be NULL to the
5869 silc_idlist_add_client function.
5871 * The funtion silc_server_packet_send_local_channel actually did
5872 not check whether the client was locally connected or not. It
5873 does that now. Fixed a bug related to LEAVE command.
5875 * Fixed Remove Channel User payload parsing bug in server's
5876 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5878 * The server's silc_server_save_channel_key now checks also the
5879 global ID list for the channel as it might not be in the local
5880 list. Fixed a bug related to LEAVE command.
5882 * Is this the end of the [<unknown>] buglet that has been lurking
5883 around for a long time? A little for loop fix in server's
5884 silc_server_command_whois_parse that is used by both IDENTIFY
5885 and WHOIS command. At least, this was a clear bug and a cause
5886 of one type of [<unknown>] buglet.
5888 * WHOIS and IDENTIFY commands call the function
5889 silc_server_command_[whois/identify]_check function even if
5890 we are not router server.
5892 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5894 * Added --with-gmp configuration option. If set the GMP
5895 is always compiled in the SILC source tree. If not set then
5896 it is checked whether the system has the GMP3 installed. If
5897 it has then the GMP won't be compiled (the system's headers
5898 and library is used), if it doesn't have it then the GMP is
5899 compiled in the SILC source tree.
5901 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5903 * Changed RSA private exponent generation to what PKCS #1
5904 suggests. We try to find the smallest possible d by doing
5905 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5906 not security fix but optimization.
5908 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5910 * Added new config entry [Identity] to fork the server and run
5911 it as specific user and group. A patch from Bostik.
5913 * Imported Dotconf configuration library into lib/dotconf.
5914 This will be used to create the SILC configuration files later.
5915 It will appear in the distsribution after this commit.
5917 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5919 * A big code auditing weekend happening. Auditing code for
5920 obvious mistakes, bugs and errors. Also, removing any code
5923 Removed files for being obsolete:
5925 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5926 inline in the file lib/silcutil/silcbuffer.h)
5928 o lib/silcutil/silcbufutil.c (the header has inline versions)
5930 Changed code to fix possible error conditions:
5932 o The buffer formatting routines now check that the destination
5933 buffer really has enough space to add the data. This applies for
5934 both buffer formatting and unformatting
5935 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5936 unformatting was changed to accomodate following rules:
5937 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5938 sent to the function while XXX_*STRING will not allocate or copy
5939 the data into the buffer. Instead it sets the pointer from the
5940 buffer into the pointer sent as argument (XXX_*STRING used to
5941 require that the pointer must be allocated already). This change
5942 makes this whole thing a bit more consistent and more optimized
5943 (note that the data returned in the unformatting with XXX_*STRING
5944 must not be freed now). The routines return now -1 on error.
5946 o Tried to find all code that use buffer_format and buffer_unformat
5947 and added return value checking to prevent formatting and
5948 especially unformatting errors and possible subsequent fatal
5951 o Changed ske->x and ske->KEY to mallocated pointers in
5952 lib/silcske/silcske.h. Fixed possible data and memory leak.
5954 o Added return value checking to all *_parse* functions. Fixed
5955 many memory leaks as well.
5957 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5958 so that buffer overflows would not happen. All code now also
5959 checks the return value as it can fail.
5961 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5963 * Added reconnection support to server if the normal server looses
5964 its connection to the router (for example if router is rebooted).
5965 The server performs normal reconnection strategy implemented
5966 to the server. Affected file silcd/server.c.
5968 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5970 * Added new packet type SILC_PACKET_SET_MODE that is used to
5971 distribute the information about changed modes (for clients,
5972 channels and clients channel modes) to all routers in the
5973 network. Updated the protocol specification accordingly.
5975 Added functions into silcd/packet_send.c and
5976 silcd/packet_receive.c: silc_server_send_set_mode,
5977 silc_server_set_mode.
5979 Added new files silcmode.[ch] into lib/silccore that implements
5980 the encoding and decoding of Set Mode Payload. Added new type
5981 SilcSetModePayload. Moved the definitions of different modes
5982 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5984 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5986 * Oops, a little mistake in server's connection authentication
5987 protocol. The protocol is not ended with FAILURE but with
5988 SUCCESS if the authentication is Ok. :) Affected file is
5991 * Implemented NICK_CHANGE notify handling in server in the file
5992 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5993 the local clients on the channel. After the changing nickname
5994 in router environment snhould work and the [<unknown>] nickname
5995 should appear no more.
5997 The silc_server_replace_id function that receives the Replace ID
5998 payload now sends the NICK_CHANGE notify type also in the file
5999 silcd/packet_receive.c
6001 * Changed WHOIS and IDENTIFY command to support the maximum amount
6002 of arguments defined in protocol specs (3328 arguments). This
6003 fixed a bug that caused problems when there were more than three
6006 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6008 * Added extra parameter, command identifier, to the
6009 silc_client_send_command so that explicit command identifier
6012 Changed that ID list routines uses specific command identifier
6013 when sending WHOIS/IDENTIFY requests to the server so that they
6014 can be identified when the reply comes back.
6016 Affected files lib/silcclient/command.[ch],
6017 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6019 * Added `sender' argument to silc_server_packet_send_to_channel
6020 to indicaet the sender who originally sent the packet to us
6021 that we are now re-sending. Ignored if NULL. Affected file
6022 silcd/packet_send.[ch].
6024 * Added some server statistics support in silcd/server_internal.h
6025 SilcServerStatistics structure and around the server code. Also
6026 send some nice statistics information when client is connecting
6029 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6031 * Fixed channel ID decoding in server's JOIN command reply in
6032 silcd/command_reply.c
6034 * Fixed braodcasting of replace ID payload to not to send it if
6035 we are standalone server in silcd/packet_receive.c.
6037 * Fixed all channel message sending routines to not to send
6038 packets to clients that has router set, since they are routed
6039 separately in the same function earlier. Affects file
6040 silcd/packet_send.c and all channel packet sending functions.
6042 * In USERS reply, res_argv[i] are not allocated, the table
6043 is allocated. Thus changed that free the table, not its
6046 * In server's whois_check and identify_check if the client is
6047 locally connected do not send any WHOIS commands - they are not
6050 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6052 * Fixed some minor bugs in client when sending WHOIS command. The
6053 arguments was in wrong order.
6055 * Removed statis function add_to_channel from server in
6056 silcd/command.c that was previously used with the joining but
6059 * Tested USERS command in router environment successfully with two
6060 routers, two servers and two clients.
6062 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6064 * Reorganized the USERS command and command reply in client library
6065 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6066 When the command is given by user we register a pending command
6067 callback that will reprocess the command after the reply has been
6068 received from the server. When reprocessing the packet we then
6069 display the information. Thus, the USERS information is displayed
6070 now in the command callback instead of in the command reply
6071 callback. The processing of the command is same as previously
6072 when server has sent the command reply in the JOINing process.
6074 * Added to USERS command in silcd/command_reply.c to join the client,
6075 we didn't use to know about, to the channel after we've created
6076 a client entry for it. Also, for clienet we did know already still
6077 check whether it is on the channel or not and add it if not.
6079 * Removed silc_server_command_join_notify as the function and its
6082 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6084 * Changed the client's pending command handling to the same as the
6085 server's pending command handling. It is also now possible to
6086 execute command reply functions from other command reply
6087 function as the function callbacks for commands and command
6088 replies are one and same. The pending commands are not static
6089 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6090 in client connection context. Thus, pending commands are server
6091 connection specific as it is convenient.
6093 Changed the function silc_client_command_pending and
6094 silc_client_command_pending_del and added new function
6095 silc_client_command_pending_check. Removed the
6096 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6099 * Added cmd_ident, current command identifier, to the client
6100 connection context in lib/silcclient/client.h to keep track on
6101 command identifiers used in command sending. Client's command reply
6102 function handling now supports the mandatory command identifiers.
6104 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6105 funtions in client to fully support pending command callbacks.
6107 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6108 as one of the arguments to the application in the command reply
6111 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6112 before first releasing SILC but came back. Now it is removed again
6113 and should come back nomore. The FORWARDED flag was used only
6114 by the JOINing procedure by forwarding the command packet to router.
6115 Now, the JOINing procedure has been changed to more generic (due
6116 to various router environment issues) and FORWARDED is not needed
6117 anymore for anything. The protocol specification is yet to be
6120 Now, removed silc_server_packet_forward from server and the flag
6121 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6123 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6125 * Renamed NAMES command to USERS command. The NAMES was named that
6126 due to historical reasons. Now it is renamed. Also, rewrote
6127 parts of the USERS command. The nickname list is not sent anymore
6128 by the server. Only Client ID and mode lists are sent in the USERS
6129 command. Changed this also to the protocol specification.
6131 The client now resolves the names and stuff after it receives
6132 the USERS list from the server when joining to the channel.
6134 * WHOIS and IDENTIFY commands has been changed to support multiple
6135 Client ID's per command. One can now search for multiple users
6136 in the network by sending only one WHOIS or IDENTIFY command.
6137 Changed the code and the protocol specifications.
6139 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6140 uses silc_server_command_whois_parse to parse the request. */
6142 * If normal server, do not parse the WHOIS and IDENTIFY requests
6143 before sending it to the router. Saves some time.
6145 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6147 * Fixed JOIN command on client library. Wrong number of arguments
6148 used to crash the client.
6150 * Added silc_server_channel_has_global function to check whether
6151 channel has global users or not.
6153 * Added silc_server_channel_has_local function to check whether channel
6154 has locally connected clients on the channel.
6156 * The silc_server_remove_from_one_channel now checks whether the
6157 channel has global users or not after given client was removed from
6158 the channel. It also checks whether the channel has local clients
6159 on the channel anymore. If it does not have then the channel entry
6160 is removed as it is not needed anymore.
6162 * The silc_server_notify now checks on JOIN notify whether the joining
6163 client is one of locally connected or global. If it is global then
6164 the channel has now global users on the channel and that is marked
6165 to the channel entry. Also, it now saves the global client to
6166 global list who is joining and JOINs it to the channel. This is
6167 for normal server, that is.
6169 Changed silc_server_send_notify_on_channel,
6170 silc_server_packet_relay_to_channel and
6171 silc_server_packet_send_to_channel check if we are normal server
6172 and client has router set (ie. global client) do not send the
6173 message to that client, as it is already routed to our router.
6175 * Implemented LEAVE notify type handling in silc_server_notify
6178 * Tested LEAVE command in router environment successfully. Tested
6179 with two routers, two servers and two clients.
6183 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6185 * Implemented SIGNOFF notify type handling in silc_server_notify
6188 * silc_server_remove_id now removes the client entry from all channels
6189 it has joined and thusly sends SIGNOFF notify type.
6191 * Rewrote the NAMES list generation in server by removing two excess
6192 loops. The lists are created now inside one loop.
6194 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6196 * silc_server_remove_channel_user checks now also global list
6197 for channel and client.
6199 * silc_server_new_channel_user checks now both local and global
6200 list for channel and client. Fixed a bug in client id decoding.
6201 Used to decode wrong buffer.
6203 * silc_server_channel_message checks now both local and global
6204 list for channel entry.
6206 * Tested channel joining (hence JOIN) in router environment
6207 successfully. Tested with two routers, two servers and two
6210 * Tested channel message sending in router environment successfully.
6212 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6214 * Added silc_server_save_channel_key into server.[ch] to save the
6215 received channel key in Channel Key payload processing. It is
6216 also used in JOIN command reply handling.
6218 Equivalent function silc_client_save_channel_key added into
6219 client.[ch] into client library.
6221 * Changed JOIN command reply to send information whether the channel
6222 was created or not (is existing already) and the channel key
6223 payload. Changed protocol specs accordingly.
6225 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6226 the request was sent by ID and not by nickname. Crashed on
6229 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6231 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6232 now correctly save the received data.
6234 * silc_server_free_sock_user_data now notifies routers in the
6235 network about entities leaving the network.
6237 At the same time implemented functions silc_server_remove_id
6238 and silc_server_send_remove_id to receive and send REMOVE_ID
6239 packets. The packet is used to notify routers in the network
6240 about leaving entities. The ID removed will become invalid in
6243 * Added function silc_idlist_del_server into server. Removes and
6244 free's server entry from ID list.
6246 * silc_server_private_message function now checks, if we are router,
6247 that the destination ID really is valid ID, naturally.
6249 * In router when NEW_ID packet is received (for new client) the
6250 hash of the Client ID is saved in the ID Cache but the
6251 client->nickname is set to NULL, instead of putting the hash
6254 IDENTIFY command now also checks that client->nickname must be
6255 valid. If it is not if will request the data from the server who
6256 owns the client. Added new function
6257 silc_server_command_identify_check.
6259 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6260 to set the command to already allocated Command Payload.
6262 * Tested private message sending in router environment with two
6263 routers, two servers and two clients. Fixed minor bugs and now
6266 * Fixed segfault from client's NAMES command. Used to crash if
6269 * Forwarded packets must not be routed even if it is not destined
6270 to the receiver. Changed server code comply with this.
6272 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * Added `require_reverse_mapping' boolean value to ServerParams
6275 structure. If TRUE (not default) the server will require that
6276 the connecting host has fully qualified domain name.
6278 If the reverse mapping is not required and hostname could not be
6279 found the IP address is used as hostname.
6281 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6283 * Implemented version string checking to both client and server.
6284 The check is incomplete currently due to the abnormal version
6285 strings used in development version of SILC.
6287 * Changed all command functions in server to use the new
6290 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6292 * Changed char *data to unsigned char *data in ID Cache system to
6293 support binary data as ID Cache data. Changed code to support
6294 binary data in lib/silccore/idcache.c.
6296 * Renamed silc_server_packet_relay_command_reply to
6297 silc_server_command_reply as it is normal packet receiving
6298 function. Rewrote the function to accept command replys for
6299 servers and not only for clients.
6301 * Mark remote router always as registered server if we are connecting
6302 to it. Otherwise, commands sent by the router to us are ignored.
6304 * All ID List find routines now returns the ID Cache Entry pointer
6305 as well if requested.
6307 * WHOIS command works now in router environment, tested with two
6308 routers, two servers and two clients.
6310 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6311 in router environment (as it is almost equivalent to WHOIS) but
6312 hasn't been tested thoroughly. Added new functions:
6314 silc_server_command_identify_parse
6315 silc_server_command_identify_send_reply
6316 silc_server_command_identify_from_client
6317 silc_server_command_identify_from_server
6319 * Disabled route cache adding because adding two different ID's with
6320 same IP replaces the old cache entry thus giving wrong route.
6321 The entry->router->connection is always the fastest route anyway
6322 so route cache may not be needed. Of course, new routes maybe
6323 established after receiving the ID when the entry->router->connection
6324 might not be anymore the most optimal.
6326 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6328 * Add route cache for received ID for fast routing.
6330 * Added silc_server_packet_route to route received packet on router
6331 that is not destined to us.
6333 * Renamed silc_server_get_route to silc_server_route_get.
6335 * Added id_string and id_string_len fields into SilcServer to
6336 include encoded ServerID for fast comparing without excess
6337 encoding of the ID's.
6339 * Cleaned up WHOIS command on server side. Added following static
6342 silc_server_command_whois_parse
6343 silc_server_command_whois_check
6344 silc_server_command_whois_send_reply
6345 silc_server_command_whois_from_client
6346 silc_server_command_whois_from_server
6348 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6349 arguments in command replies. All command functions should be
6350 updated to use this macro.
6352 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6354 * Minor typo fixes on command reply handling on server.
6356 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6358 * Added silc_server_command_add_to_channel internal routine to add
6359 the client to the channel after router has created the channel and
6360 sent command reply to the server.
6362 * Added generic silc_server_send_command to send any command from
6365 * Use static buffer with ID rendering instead of duplicating data.
6367 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6369 * Fixed a channel user mode bug when joining to a channel server gave
6370 everybody channel founder rights, oops.
6372 * We mark ourselves as the router of the incoming server connection
6373 if we are router ourselves. This way we can check in some packet
6374 sending functions whether it is locally connected server. For
6375 incoming router connections we put NULL.
6377 * For router sending packets locally means now always sending the
6378 packet cell wide; to local clients and local servers. For normal
6379 server sending packet locally means sending it to only local
6382 * Fixed the JOIN command to really work in router environment. If the
6383 channel is created it is always created by the router. Router is
6384 also responsible of making the initial joining to the channel,
6385 sending JOIN notify to the sending server and distributing
6386 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6387 does not exist server doesn't do anything else but forward the
6388 command to the router which performs everything.
6390 * Added silc_server_send_channel_key function to send the Channel Key
6393 * Added silc_server_create_channel_key to create new channel key. The
6394 channel key is now re-generated everytime someone joins or leaves
6395 a channel, as protocol dictates. Note: channel->key_len is the
6398 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6400 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6401 packet_receive.[ch] to separate packet sending and receiving
6402 routines. The server.[ch] now includes everything else including
6403 actual packet processing (writing and reading data) and other
6406 Renamed silc_server_private_message_send_internal to
6407 silc_server_send_private_message. The routine is still though
6408 used only to relay private messages as server does not send
6409 private messages itself.
6411 Renamed silc_server_new_channel to silc_server_create_new_channel
6412 and added new function sicl_server_new_channel that handles the
6413 incoming New Channel packet. Added also new sending function
6414 silc_server_send_new_channel to send New Channel Payload.
6416 * Added new function silc_server_notify to process incoming notify
6417 packet to the server/router. Server may then relay the notify
6418 to clients if needed.
6420 * Added new function silc_server_new_channel_user to process incoming
6421 New Channel User packet. Router will redistribute the packet and
6422 send JOIN notify to its local clients and locally connected servers
6423 if needed. Normal server will send JOIN notify to its local client
6424 on same channel when received this packet. Added also corresponding
6425 sending function silc_server_send_new_channel_user to sent the
6428 * Added boolean route argument to send_notif_to_channel and
6429 packet_send_to_channel functions to attempt to route the packet
6430 if it is TRUE and send only locally if it is FALSE.
6432 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6434 * silc_server_replace_id now broadcasts the received replace ID
6435 packet if it is not broadcast packet already. The router must
6436 broadcast to inform other routers about changed ID.
6438 * Added backpointer to server's router into SilcServer context in
6439 silcd/server_internal.h.
6441 * Fixed silc_server_packet_broadcast to send correct broadcast
6444 * The channel key is now distributed to the local client as soon
6445 as it is received from the router (in router environment) so that
6446 no other packet may be sent for the channel until client has
6449 * silc_server_remove_channel_user now broadcasts the received
6450 Remove Channel User packet if it is not broadcast packet already.
6451 The router must broadcast to inform other routers about removed
6454 * Added users field into SilcPacketContext that is a reference count
6455 of the context. One can increase the reference count by calling
6456 silc_packet_context_dup which is now changed to just increase the
6457 reference count instead of duplicating the data. The reference
6458 count is decresed by calling silc_packet_context_free that will
6459 free the data after the reference count hits zero.
6461 For now on the packet context and everything allocated into it
6462 (including the raw packet from network) must be freed by calling
6463 the new silc_packet_context_free function. Added also new function
6464 silc_packet_context_alloc that must be used now to allocate the
6465 context. This also means that if a routine is asynchronous from
6466 silc_[client/server]_packet_parse_type the packet context must
6467 be duplicated by calling silc_packet_context_dup. Otherwise it
6468 gets free'd after silc_[client/server]_packet_parse_type returns.
6469 Also, one must remember that if packet is duplicated then its
6470 reference count must be decresed by calling the free function as
6471 many times as it was duplicated.
6473 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6474 from both client and server.
6476 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6478 * Made joining to a channel working in router environment.
6480 * Cleaned up JOIN command on server side and create function
6481 silc_server_command_join_channel internal routine to make the
6484 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6486 * Changed silc_command_pending list to SilcDList. Also, added
6487 `ident' field to SilcServerCommandPending structure to identify
6488 the reply and to call correct callback.
6490 Added silc_server_command_pending_check function to replace the
6491 corresnponding macro. The silc_command_pending list is not
6494 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6495 to set identifier to previously allocated Command Payload. It
6496 is used to set identifier for command when resending Command
6499 * Added silc_command_payload_encode_payload to encode Command
6500 Payload buffer from SilcCommandPayload structure.
6502 * Added silc_argument_payload_encode_payload to encode Argument
6503 payload buffer from SilcArgumentPayload structure.
6505 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6507 * Changed WHOIS command to support router connection on server side.
6508 The whois request is always sent to router unless the server is
6509 standalone server. After server has received the reply from the
6510 router will it send the reply to the client.
6512 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6513 broadcast received broadcast packet. The function is used only
6514 by router. The broadcast packet is always sent to the router's
6517 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6518 render given ID to printable string, for log files for example.
6520 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6522 * Made basic router to router connections working. At least they
6523 can now connect to each other but nothing really works the way
6524 they are supposed - yet.
6526 * Added new initiator token to RouterConnection configuration
6527 file in silcd/serverconfig.[ch]. It is used to tell whether we
6528 are the initiator to the remote router or whether we'll expect
6529 the other end to connect.
6531 * Moved registering of listener task to silc_server_init, hence
6532 the server starts listenning as soon as it is run, even if it
6533 does not have connections to other routers. Let's see how well
6536 * Changed default connection retry timeouts for more suitable in
6539 * Removed cipher and such arguments from silc_idlist_add_client
6540 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6541 Added new function silc_idlist_add_data to add the keys and stuff
6544 * Added SilcIDListData structure and added it to SilcClientEntry
6545 and SilcServerEntry as their first field in the structure. This
6546 way we can explicitly cast the ID entries to the SilcIDListData
6547 structure and get common data for the entries. In past, we had
6548 to first check what type of connection it is and then cast it to
6549 correct ID entry type. Now, we can directly cast the opaque
6550 pointer to the SilcIDListData (no matter what ID entry it actually
6551 is) and get the data needed.
6553 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6555 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6556 in some circumstances even if threre were timeout tasks, though not
6557 IO tasks, but tasks anyway. Now fixed.
6559 * Defined SilcServerConnection structure to hold connection specific
6560 stuff about directly connected servers and routers. The definition
6561 is currently in silcd/server_internal.h. I thought about having
6562 a bit more important role fro this struct but for now it is used
6563 only when connecting to other server (or router actually).
6565 * Added connecting retry support in server when connecting to
6566 router(s). The retry feature implement exponential backoff
6567 algorithm. Also, added SilcServerParams structure to hold default
6568 parameters for server. For now, it include these retry settings
6569 and are hard coded. After server is moded to be as Silc Server
6570 Library this structure will be more important.
6572 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6574 * Changed client librarys channel->clients table to SilcList and
6575 changed code accordingly.
6577 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6579 * Changed client's channel table to SilcList and changed code
6580 accordingly. Also changed SilcChannelClientEntry to include back-
6581 pointer to the channel so that client entry can use that structure
6582 as list as well and we have fast cross-reference to the channel.
6583 This change dramatically decreased the complexity of channel
6584 handling with client entry and vice versa (removed one extra
6585 loop when searching for channel entry from many functions).
6587 * Changed server->sim from table to SilcDList and changed code
6590 * NAMES command can now be used from user interface. It will show
6591 the user list on the channel, neatly.
6593 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6594 Code now saves realname of the user if it becomes available.
6596 * Renamed configure.in to configure.in.pre and made ./prepare
6597 script to automatically add correct version string to
6598 configure.in which it creates from configure.in.pre.
6600 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6602 * NAMES command reply now shows users mode with the nickname when
6605 * Moved silc_client_ch[u]mode[_char] functions from
6606 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6607 place sucks, they are utility functions and should be in some
6610 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6612 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6615 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6619 * Added TRQ (efficient deque and list library) into lib/trq. This is
6620 a very good list library that is currently used in the SILC. Defined
6621 SilcList API over the library because I didn't like the API very
6622 much. See lib/trq/silclist.h for the API and examples of how to
6623 use the API. Fixed various places in the code to use the new
6624 SilcList API. The SilcList is meant for lists that has a structure
6625 already defined as a list. It is not suitable to add just some
6626 context to the list (in TRQ, the context is the list actually).
6628 So, I defined SilcDList that can be used for the purpose where
6629 predefined list structure does not exit. This can be used as
6630 such list. Now some context just can be added to the SilcDList.
6631 Currently this list is not used in the SILC just yet, though there
6632 are a lot places where this can replace dynamically allocated
6633 tables and I will fix these places, later, to use SilcDList.
6634 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6635 and use TRQ internally).
6637 Also fixed some annoying warning messages that the original TRQ
6638 code generated. Also minor changes to TRQ's Makefile.in.
6640 * Added support for querying by Client ID to both WHOIS and
6641 IDENTIFY commands into server, as required by the protocol.
6643 * Removed method function pointers from SilcBuffer structure. They
6644 weren't used to anything and just increased the context size for
6645 no good reason. This change also made silc_buffer_alloc and
6646 silc_buffer_free functions inline functions.
6648 * Disabled command flooding detection support until it's fixed so
6649 that it accepts commands in but does not execute them more than once
6652 * Added silc_net_localhost(), to return local hostname, into
6653 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6654 that must be initialized before calling silc_client_init.
6656 * Added new function: silc_server_send_notify_on_channels to send
6657 notify messages to all channels client has joined. It is assured
6658 that the message is sent only once per client.
6660 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6661 lib/silcutil/silcutil.[ch] as silc_format function. The new
6662 function is generic and is used by server as well, not only by
6663 the logging routines.
6665 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6666 the provided version string was not acceptable. Added new function:
6667 silc_ske_check_version into lib/silcske/silcske.h. The function
6668 must be implemented by the application (client or server) and it
6669 does not reside in the SKE library. The function checks the version
6670 string remote end sent.
6672 * Added back pointers (to opaque context and to SilcSocketConnection)
6673 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6675 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6676 duplicate packet context structure.
6678 * Changed `notify' client operation to send same arguments as client
6679 receives from server except for ID's. ID's are mapped to correct
6680 ID entry and that is returned. Also, if channel entry is not sent
6681 by server but the notify is for channel the channel entry is sent
6682 to application (otherwise application doesn't know that it is for
6683 channel (library gets it from packet's Destination ID)).
6685 * Added silc_client_remove_from_channels into client library to
6686 remove a client from all channels it has joined to. Used when
6687 received SIGNOFF notify from server. Added also new function
6688 silc_client_replace_from_channels to replace old ID entry with
6689 new ID entry on all channels. Used when received NICK_CHANGE
6692 * Fixed ID Cache list handling in silc_idlist_get_client in
6693 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6694 to get (or query) client by ID.
6696 * Updated TODO list.
6698 * Added connection authentication status message defined by the
6699 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6700 support for these into the code in client and server side.
6702 * Added generic function silc_client_send_command to send any command
6703 with variable argument list. Application should use this function
6704 to send commands if the command functions provided by the library
6705 does not suite for the application's user interface needs.
6707 * Added new `failure' client operation. Application is notified about
6708 received failure packet if client is executing a protocol. In this
6709 case the protocol's execution has failed.
6711 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6712 is required by the protocol.
6714 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6715 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6718 * Added status flag to SilcSKE object to indicate realtime status
6719 of the SKE protocol.
6721 * Application receives now exactly same command reply arguments as
6722 the library receives from server. However, if ID is received the
6723 corresponding ID entry is returned to the application (eg. Client
6724 ID is mapped to correct SilcClientEntry entry and that is returned).
6725 Changed command_reply client operation due to this change.
6727 * Changed all ID's in commands and in command replys as ID Payloads.
6728 Change affected both client and server side codes.
6730 All ID's sent in SILC network (with execption of ID's in SILC
6731 Packet header) are sent in ID Payload to support variable length
6734 * Server now notifies nick changes and notifies all clients on
6735 the channels about the new nickname (about the new Client ID,
6738 * Implemented CMODE command to change channel modes. Supports all
6739 channel modes defined by the protocol specs except ban and invite
6740 lists. (Also, private channel key mode is supported but support for
6741 setting private channel key in client is missing, thus, this mode
6742 has no effect on client side (except that server requires that the
6743 client uses private channel key and normal channel traffic does not
6746 Also, invite mode works per se, but INVITE command does not work
6747 yet correctly, so you can set channel as invite only channel but
6748 inviting clients to the channel does not work (it is yet to be
6749 thought what's the best way to do it).
6751 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6752 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6753 Implemented CUMODE command to change user's mode on the channel.
6754 Supports all modes defined by the protocol specs.
6756 * Added NAMES command reply to return users modes on the channel.
6758 * Removed unnecessary and slow ciphers from lib/silccrypt.
6760 * Set SO_KEEPALIVE option to connection sockets by default.
6762 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6764 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6765 redefined the Notify Payload into protocol specs.
6767 * Added silc_id_payload_parse_id to get ID directly from raw
6770 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6772 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6773 accept searching by Client ID as well.
6775 * Added support for LEAVE and SIGNOFF notify types in client library.
6777 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6778 to parse ID Payload from raw data.
6780 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6782 * Added flags parameter into silc_ske_assemble_security_properties
6783 function in lib/silcske/silcske.[ch].
6785 * Changed notify client operation to fit better for notify messages
6786 sent by server. The notify payload received from server is now
6787 passed to the application (after parsing it to SilcNotifyPayload).
6788 It is application's responsibility to retrieve the arguments
6789 from the payload and show the message the way it wants. The message
6790 sent by server is implementation specific.
6792 * Changed public keys to comply with the protocol specification.
6793 Old public keys are not supported anymore and are not compatible.
6795 * Removed nickname from Channel Payload as the latest draft removed
6796 it. The client must resolve the nickname from the NAMES command
6797 reply received when it joined the channel.
6799 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6801 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6803 * Fixed some errors in protocol specification drafts.
6805 * Created lib/silccore/silcnotify.c to implement Notify Payload
6806 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6807 generic payloads described by protocol specifications. The file
6808 includes implementations for ID Payload and Argument Payload.
6810 * Changed Command Payload implementation to use the new Argument
6811 Payload. Changed command_xxxx_payload to command_payload_xxxx
6812 to comply with SILC coding conventions.
6814 * Added suppport for Argument Payload handling in Notify Payload
6815 implementation as protocol requires it. Added the new support
6816 into server and client lib as well.
6818 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6820 * Added support for multiple nicknames on same channel. [n] is
6821 added locally to the nickname if there are more than one same
6822 nicknames on the channel.
6824 * Server now sends all nicknames that matched WHOIS request.
6825 Client also shows the list received from server.
6827 * Added TOPIC command to client side. User can now set and show
6828 current topic on channel.
6830 * Added MOTD command to client and server. Also, server sends the
6831 motd when client connects to the server.
6833 * Changed version strings to comply ISO 8601.
6835 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6837 * Fixed protocol error handling in client library. It should now
6838 cope even if the SKE fails for some reason.
6840 * Made new protocol specification drafts for submitting to IETF.
6842 * Implemented TOPIC command to server in silcd/command.c.
6844 * Added two new notify types into lib/silccore/silcnotify.h:
6845 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6846 notify nickname change and topic setting/change on a channel.
6848 * API change of command_reply operation in client library. The
6849 application gets now the status type received from server as well.
6851 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6853 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6855 * Cras fixed and optimized the packet handling even further and
6856 it should work now. Minor change to the prototype of function
6857 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6859 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6861 * Added new function into lib/silcutil/silcschedule.[ch]:
6862 silc_schedule_with_fd to select() a specified fd. The function
6863 returns after timeout expires or data arrives or goes. The
6864 function is used by packet routines to wait that all data is
6865 received from network.
6867 * Fixed data reading from network in lib/silccore/silcpacket.c.
6868 The code now assures that all data is read from the fd and then
6869 continues packet processing. This was a bug fix since the code
6870 used to drop some data in some circumstances.
6872 * Added new function into lib/silcclient/client.[ch]:
6873 silc_client_start_key_exchange to start key exchange after
6874 connection has been established to server. The code internally
6875 now uses this funtion but its main purpose was to provide it
6876 for applications that perform their own connecting. After
6877 application has created a connection it merely calls this
6878 function to start the key exchange between client and server.
6879 The library takes care of everything else after that.
6881 Updated also lib/silcclient/README to explain the usage of
6884 * Do not send to application information that connection has
6885 been established. Application gets notified it by connect
6888 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6890 * Applied cras's patch to add silc_schedule_one function. The
6891 function runs scheduler once and returns.
6893 * Fixed the scheduler after cras messed it up. The timeout
6894 handling works now as it's supposed to work.
6896 * Added into lib/silccore/ silcnotify.h to include notify
6897 message types support. Changed silc_server_send_notify*
6898 functions, in server.[ch], to support those new notify types.
6899 Added the support for the notify types into client library,
6900 as well. Added new notify client operation into ops.h in
6903 * Changed silc_server_packet_send_to_channel to send normal
6904 packets instead of just channel message packets. The function
6905 is now used to send the notify packets to channels. It is not
6906 used to send channel message packets anymore, as server never
6909 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6910 va_arg()s as it seems to require it nowadays. I guess, if SILC
6911 is compiled with older va_arg() the new code should work anyway.
6913 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6915 * Splitted core library. Core library (lib/silccore) includes
6916 now only SILC protocol specific core (and common) components.
6917 Created new utility library (lib/silcutil) that includes more
6918 generic purpose stuff. The stuff for util library was taken
6919 from the old core library. This was minor and easy split.
6921 * Created SILC Client Library (lib/silcclient) that includes
6922 implementation of the SILC client without user interface. This
6923 was major move from silc/ directory. The code has been changed
6924 so that it is transparent towards the user interface. The
6925 silc/ directory includes now the same user interface as before
6926 and it uses the new client library. Read lib/silcclient/README.
6927 Basicly, the client library performs everything else related
6928 to SILC except user interface handling. Also, configuration
6929 files are considered to be part of user interface and library
6930 does not handle them.
6932 This change also changed a lot of structures, function naming etc.
6933 Most important change was that SilcClientWindow object was
6934 renamed to SilcClientConnection in the client library. Created
6935 also new file lib/silcclient/ops.h. Also added new files
6936 silc/local_command.[ch] and silc/client_ops.[ch].
6938 All these changes were made to make it easier for user interface
6939 designers to create what ever user interface for the SILC client
6942 It is also expected that the server will be moved to lib
6943 directory as well and SILC Server Library will be created;
6944 sometimes in the future.
6946 * Removed Local commands from lib/silccore/silccommand.h as
6947 they are application specific and new client library does not
6948 handle any of those anymore.
6950 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6951 old client implementation in silc/.
6953 * Added support for callback functions in SILC_LOG_* macros.
6954 Application can now set its own callbacks that will be called
6955 instead of using the default functions that will always print
6956 the debug messages to stderr (or stdout). Also, debugging can
6957 now be disabled by setting silc_debug to FALSE and re-enabled by
6958 setting it to TRUE. Note, that logging will still work even
6959 if debugging is disabled.
6961 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6962 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6963 silc_log_reset_debug_callbacks.
6965 * To enable debugging in silc client one must give now -d
6966 option on command line.
6968 * Changed silc_schedule_init to automatically allocate task queues
6969 if they are not allocated before calling it.
6971 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6973 * Added GMP 3.1 into math library.
6975 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6977 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6978 a channel in SILC network. The packet is used by servers and
6979 routers to notify other routers that user has left a channel.
6980 This little feature was missing until now. Added the feature
6981 to protocol specification as well.
6983 Added functions: silc_server_send_remove_channel_user and
6984 silc_server_remove_channel_user into server.[ch].
6986 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6987 lib/silccore/silcpacket.h. However, they are not implemented
6990 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6992 * Fixed joining to a channel and sending channel messages
6993 between server and router. The channel message sending should
6994 now work inside a cell.
6996 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6998 * Fixed the private message sending between server and router.
6999 The private message sending should now work inside a cell.
7001 * Added silc_server_replace_id into server.[ch] to replace
7002 existing ID in the SILC network.
7004 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7005 and silc_idlist_replace_server_id into idlist.[ch] in server.
7007 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7009 * Fixed the server to server connections. Server can again now
7010 connect to router. Router to router connections probably does
7013 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7015 * Added dynamic protocol registering support. Now protocols can
7016 registered and unregistered on the fly. Patch by cras.
7018 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7020 * Added lib/contrib directory to hold routines that some platforms
7021 don't have but are needed by SILC.
7023 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7024 into lin/contrib to provide getopt() and getopt_long() for
7025 those who don't have it.
7027 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7029 * Added AWAY command to client. When away message is set and
7030 client receives a private message packet the client automatically
7031 replies to the sender with the away message.
7033 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7034 bug seemed to be the cause of recent problems when compiling
7037 * Added version detection support to SKE protocol specification
7038 and added the new changes to the SKE implementation as well.
7039 There were other minor changes in the SKE protocol as well.
7041 Many changes in lib/silcske/silcske.[ch] and in
7042 lib/silcske/payload.[ch].
7044 * Added ^U functionality, clear input line. Patch from cras.
7046 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7048 * Mainly small bugfixes on core library. Fixed some debugging
7049 logging and buffer overflow in silclog.c.
7051 * Updated config.sub and config.guess on the distribution tree.
7053 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7055 * Added command lagging support in server. Client may execute
7056 commands now only once in two seconds.
7058 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7060 * Optimized packet reception. MAC computation and checking is now
7061 also more optimized. A lot previously duplicated code is now
7062 used as generic by both client and server.
7064 * Fixed key pair generation in clientutil.c
7066 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7068 * Added into lib/silccore/silcbufutil.[ch] new function;
7069 silc_buffer_realloc.
7071 * Moved generic packet sending/encryption functions to
7072 lib/silccore/silcpacket.[ch] from client and server. Some
7073 rewriting of the functions.
7075 * Moved all generic packet reception/decryption functions to
7076 lib/silccore/silcpacket.[ch] from client and server. The
7077 packet processing is now much cleaner in both client and server.
7078 These were major changes in both client and server.
7080 * Created many common functions in server to do packet sending.
7081 Previously code were duplicated a lot, this has been removed
7084 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7086 * Rewrote major parts of the ID cache system. Don't know
7087 whether it is better now or not but at least the API is more
7090 * Major rewrite on ID cache stuff on client because of the ID
7091 cache API changes. Added idlist.c to client.
7093 * Also major rewrite on ID cache stuff on server as well.
7094 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7095 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7096 in hand, instead they are all put into the ID cache system now.
7097 All server_idlist_* routines uses ID cache now instead of
7098 traversing its own lists (those lists does not exist anymore).
7099 SilcIDList though still exists. Also, SilcXXXEntry's are
7102 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7104 * Finally made the SKE implementation compliant to the protocol
7105 specification. All mp integers are now binary encoded as
7106 opposed being HEX encoded.
7108 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7111 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7112 functions: silc_[encode/decode]_pem. Also added function
7113 silc_encode_pem_file to PEM encode with newlines ('\n') for
7116 * SILC public keys are now encoded either PEM or binary. Same
7117 option is for private keys as well. By default private keys
7118 are binary encoded and public keys PEM encoded. Silly HEX
7119 encoding were removed.
7121 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7122 function to create fingerprints.
7124 * Fixed a bug in SHA1; does not change the original data anymore.
7126 * Partly implemented INFO command on client and server side.
7127 Fixed CLEAR command. Changes to SERVER command; show current
7128 server(s) when giving command without arguments. Added
7129 VERSION command to client.
7131 * Added check to server that unregistered connections cannot
7132 execute commands (unless it is specificly allowed).
7134 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7136 * Fixed screen refresh.
7138 * Fixed channel joining bug from client. On some circumstances
7139 client tried to join to a channel it had already joined.
7141 * Added public key verification process into client's protocol.c.
7142 The client now verifies the public key from user and saves
7143 it into ~./silc/serverkeys/ directory.
7145 Added into: clientutil.[ch]: silc_client_verify_server_key.
7147 * Changed SKE protocol's silc_ske_initiator_finish function
7148 to accept callback function that verifies the received public
7149 key. Removed old silc_ske_verify_public_key function.
7151 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7153 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7154 silc_pkcs_private_key[_data]_set.
7156 * Made the password and public authentication more cleaner in
7157 server's protocol.c.
7159 * Removed historic and obsolete protocol `channel_auth' from
7160 both client and server.
7162 * Removed wrong way of sending command status messages from
7163 server to client in server's command.c. The old way violated
7164 protocol specification.
7166 Changes to silccore/silccommand.[ch]: removed
7167 silc_command_encode_status_payload -> not needed anymore,
7168 changed silc_command_encode_payload_va to accept extra
7169 argument on variable argument list. The argument type must
7170 now be provided to the function. Also, added new function:
7171 silc_command_encode_reply_payload_va which is same as
7172 normal command_encode_payload_va except command status type
7173 is provided as extra argument.
7175 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7177 * Added ~./silc directory handling. The directory includes the
7178 public and private keys for the client.
7180 Added silc_client_check_silc_dir, silc_client_create_identifier
7181 and silc_client_load_keys.
7183 * Implemented SILC protocol compliant public key. Added public
7184 and private key saving to and loading from files.
7186 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7187 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7188 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7189 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7190 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7192 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7193 silc_pkcs_load_[public/private]_key.
7195 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7197 * Added silc_server_get_route (route.[ch]) to get connection
7198 data for the fastest route for given ID.
7200 * Implemented INVITE command on client and server. The command
7201 were re-defined in the SILC Protocol Specification and the
7202 implementation now complies with the specification.
7204 * Implemented PING command on client and server.
7206 * Implemented NAMES command on client and server. The server side
7207 supports currently only normal server not router server yet.
7208 Some changes to NAMES definition in SILC protocol specification.
7210 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7212 * Implemented LEAVE command on client and server.
7214 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7215 again. This change was made to the protocol as well. Server
7216 should not violate the protocol specification anymore.
7218 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7220 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7221 was tested. SOCKS4 was not but should work anyway.
