3 * Added `prefer_ipv6' argument to the functions
4 silc_net_gethostbyname[_async]. If it is TRUE it will return
5 IPv6 address over IPv4. If FALSE IPv4 address is returned
6 even if IPv6 address was found. Affected files
7 lib/silcutil/silcnet.[ch].
9 * Added support silc_net_create_connection[_async] to fallback
10 to IPv4 address if IPv6 address could not be used (like if
11 it doesn't work on a specific system). Affected file in

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

65 to the lib/silcutil/silcbuffer.h.
67 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
69 * Added `user_count' to the SilcChannelEntry which now tells the
70 number of users on the channel. The user count is now saved
71 in normal server of global channels as well. Affected files
72 silcd/server.c, idlist.h, packet_receive.c and command.c.
74 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to

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

163 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
165 * Added new configuration options and blocks:
166 keepalive_secs, reconnect_count, reconnect_interval,
167 reconnect_interval_max, reconnect_keep_trying and
168 require_reverser_lookup. Added ConnectionParam block, and
169 implemented the connection parameters when connecting as
170 initiator and when accepting connections as responder.
172 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
173 whether given configuration value has been given already.
175 Affected files silcd/serverconfig.[c], server.[c].
177 * Splitted the doc/example_silcd.conf.in. Separated the crypto
178 algorithm parts and created new file silcalgs.conf, that
179 is now included from the example_silcd.conf.in.
181 * Optimized the silc_server_connect_to_router_second to take
182 the connection configuration object from the SilcServerConnection
183 object instead of finding it during the connecting phase.
184 Added the configuration object to SilcServerConnection struct.
185 Affected files silcd/server_internal.h, server.c.

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

262 correct client. Affected file lib/silcclient/client_notify.c.
264 * Make silc_rng_alloc fail if it cannot allocate the sha1
265 hash algorithm. Affected file lib/silccrypt/silcrng.c.
267 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
269 * Fixed the file transfer's key agreement payload to include
270 zero port also if the hostname is NULL because it could not
273 Call file transfer monitor callback now also if error occurs
274 during key agreement protocol.
276 Changed the silc_client_file_send interface to return the
277 SilcClientFileError instead of session id. The session ID
278 is returned into pointer provided as argument.
280 Check that the file exists locally before sending the
281 file transfer request at all.
283 Affected file lib/silcclient/client_ftp.c, silcapi.h.

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

317 the table with foreach callback. The current entry may
318 become invalid in the callback but it was referenced after
319 the callback returned.
321 Do not allow auto rehashing of hash table during the
322 silc_hash_table_foreach operation, for same reasons as it is
323 not allowed for SilcHashTableList. Affected files are
324 lib/silcutil/silchashtable.[ch].
326 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
328 * Defined DLLAPI into silcincludes.h and silcwin32.h for

332 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
334 * Fixed private message handling. It used some old code that
335 caused the client to crash. Affecte file is
336 lib/silcclient/client_prvmsg.c.
338 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
340 * Added function silc_client_add_channel,
341 silc_client_replace_channel_id, and removed functions
342 silc_client_new_channel_id and silc_idlist_get_channel_by_id
345 * Added cross reference of the joined channels to the
346 SilcClientEntry, and changed the SilcChannelEntry's
347 users list to SilcHashTable. The affected files are
348 lib/silcclient/idlist.[ch].
350 * Fixed a bug in hash table tarversing. While the hash table
351 is traversed with SilcHashTableList the table must not be
352 rehashed. It is now guaranteed that auto rehashable tables
353 are not rehashed while tarversing the list. Also defined that
354 silc_hash_table_rehash must not be called while tarversing
355 the table. Added function silc_hash_table_list_reset that must
356 be called after the tarversing is over. The affected files are
357 lib/silcutil/silchashtable.[ch].
359 * Changed all hash table traversing to call the new
360 silc_hash_table_list_reset in server and in client library.
362 * Added function silc_client_on_channel to return the
363 SilcChannelUser entry if the specified client entry is joined
364 on the specified channel. This is exported to application as
365 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
367 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
369 * Fixed founder regaining problem with JOIN command on normal
370 server. The notify for mode change must be sent always and
371 not only if !cmd->pending. Affected file silcd/command.c.
373 * Fixed the WHOWAS command's reply sending to support the
374 lists correctly. Affected file silcd/command.c.
376 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
378 * When sending JOIN command to router for processing the
379 sender's old command identifier was not saved back to the
380 sender's command context, fixed now. The affected file is
383 * Create the key in JOIN command of the router did not return
384 the channel key, added check for this. Affected file is
387 * Fixed a channel ID update bug in JOIN command reply. Do
388 not directly upgrade the ID but call the function
389 silc_idlist_replace_channel_id if the ID was changed.
390 Affected file silcd/command_reply.c.
392 * Fixed memory leaks from command calling if it would fail.
393 Affected file silcd/command.c.
395 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

405 * Removed TRQ from lib/trq, not needed anymore.
407 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
408 with server connections. Later this will be configurable
409 in config file after new config file is done. Affected file
412 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
414 * Fixed a crash in server related to channel announcements.
415 Affected file silcd/server.c.
417 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
419 * Fixed memory leaks in silc_server_create_new_channel*
420 functions. Affected file silcd/server.c.
422 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
423 which ID was changed. This way the router will send the
424 user list for the channel again, and server won't be in
425 desync in some rare circumstances. Affected file is
426 silcd/packet_receive.c.
428 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
430 * Check for NULL socket pointer in the function

456 * Added server & router operator statistics updating. Affected
457 file silcd/packet_receive.c and silcd/command.c.
459 * Fixed the SERVER_SIGNOFF notify handling on normal server
460 not to save the history information for clients. Same was
461 fixed earlier in remove_clients_by_server function, but not
462 here. Affected file silcd/packet_receive.c.
464 * Raised the default connection-retry count from 4 to 7 in
465 server. Affected file silcd/server.h.
467 * Cancel any possible reconnect timeouts when we start the
468 key exchange. Affected file silcd/server.c.

475 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
477 * Fixed the NICK command to always give the unformatted
478 nickname to the one giving the NICK command. If unformatted
479 nickname is cached already it will be formatted and the
480 local entry will always get the unformatted nickname.
481 Affected file lib/silcclient/idlist.c.
483 * Fixed some double frees from client library commands.
484 Affected file is lib/silcclient/command.c.
486 * Fixed CUMODE command in server to assure that no one can
487 change founder's mode than the founder itself, there was a
488 little bug. Affected file silcd/command.c.
490 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
492 * Removed the SilcClientCommandDestructor from the client
493 libary, it is not needed anymore. Affected files are
494 lib/silcclient/silcapi.h, command[_reply].[ch],
495 client_notify, idlist.c.
497 * Fixed GETKEY command to first resolve client, and then
498 resolve the server only if the client was not found, instead
499 of resolving both at the same time. Affected file is
500 lib/silcclient/command.c.
502 * Added silc_client_start_key_exchange_cb and lookup the
503 remote hostname and IP address before starting the key
504 exchange with server. The affected file is
505 lib/silcclient/client.c.
507 * The server's public key is now saved using the IP address
508 of the server and not the servername for the filename.
509 The hostname public key filename is checked as an fall back
510 method if the IP address based filename is not found.
512 Fixed the GETKEY command to save the fetched server key
515 Print the remote server's hostname now when new key is
516 received during connection process. Affected file is
517 irssi/src/silc/core/client_ops.c.
519 * Return always our own public key to the client if it asks
520 for it with GETKEY command. Affected file silcd/command.c.
522 * Removed the use_auto_addr variable from default config
523 file since it was in wrong section. Affected file is
526 * Fixed TOPIC_CHANGE notification to not route it when it
527 was sent using silc_server_send_notify_to_channel function.
528 Affected file silcd/command.c.
530 * Fixed silc_server_send_notify_kicked to send the kicker's
531 Client ID also, it was missing. Affected files are
532 silcd/command.c, silcd/packet_send.[ch].
534 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
536 * Do not save client history information in SERVER_SIGNOFF.
537 Fixes the bug in normal server that it does not detect
538 the client becoming valid after the server becomes back
539 online. Affected file silcd/server_util.c.
541 * Added `sock_error' field into the SilcSocketConnection
542 context. When error occurs during socket operation (read
543 or write) the error is saved. Added also new function
544 silc_socket_get_error to return human readable socket error
545 message. Affected files are lib/silcutil/silcsockconn.[ch],
546 lib/silcutil/unix/silcunixsockconn.c, and
547 lib/silcutil/win32/silcwin32sockconn.c.
549 * The server now prints the socket error message in the
550 signoff for client. Affected file silcd/server.c.
552 * Fixed the `created' channel information sending from router
553 to server in JOIN command. Checks now whether the channel
554 really was created or not and set it according that.
556 Fixed the JOIN command to use the client entry's current
557 ID during the joining procedure instead of the one it sent
558 in the command (it is checked though), since it can change
559 between the packet processing and command processing, and
560 would just case unnecessary pain in the client end. Affected
561 file silcd/command.c.
563 * Fixed a channel key payload sending to use correct channel
564 ID when the server was forced to change the channel's ID by
565 router. Router sent the key payload with the old Channel ID.
566 Affected file silcd/packet_receive.c.
568 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
570 * Call silc_server_save_channel_key only if the key payload
571 was provided in the JOIN command's command reply. Affected
572 file silcd/command_reply.c.
574 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
576 * Fixed silc_mp_sizeinbase to return the value correctly with
577 MPI. Affected file lib/silcmath/mp_mpi.c.
579 * Fixed the stop_server signal to correctly stop the scheduler
580 and gracefully stop the server when SIGTERM or SIGINT signals
581 are received. Affected file silcd/silcd.c.
583 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
585 * Simple handling of TERM and HUP signals. Also added some log
586 flushing call around. Affected file is
589 * Fixed small bugs in silclog.c. Now buffering output will take
590 effect after 10 seconds since startup: This will ensure that
591 no important startup messages are lost. Also output redirection
592 will preserve original format ([Date] [Type] message).
593 Affected file is lib/silcutil/silclog.c.
595 * Added two options to the config file, in the logging section:
596 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
597 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
599 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
601 * Do not print the warning about log files not being initialized
602 more than once to avoid excess logging. Affected file is
603 lib/silcutil/silclog.c.
605 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
606 the SIM copying in make install in Makefile.am.pre.
608 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
610 * Rewritten silclog APIs. Globally interesting changes follows:
611 silc_log_set_files() changed to silc_log_set_file().
612 silc_log_set_callbacks() changed to silc_log_set_callback().
613 ROBOdoc documented silclog header file.
614 SilcLogCb now returns bool to wether inihibit the default
615 handler or not (to keep the old behaviour return always TRUE).
616 The new APIs should also fix the problem of the
617 silcd_error.log file that was written in the current directory.
620 Log files streams will remain opened after silc_log_set_file()
621 call, means less CPU usage notably on high traffic servers.
622 File streams are now full buffered, and flushed to the disk
623 every 5 minutes, lesses HD activity and CPU usage.
624 Messages can be redirected, allowing admins to configure
625 one single logfile for all server messages.
626 the silc_log_quick global variable to activate fast-logging.
627 Affected files lib/silcutil/silclog.[ch]
629 * Changed some code to conform new silclog APIs. Affected
630 files are doc/example_silcd.conf.in, silcd/server.c
631 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
634 * Fixed a memory leak that could occur in some situations.
635 Affected file silcd/serverconfig.c.
637 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
639 * Added the silc_client_del_client to remove the client from
640 all channels as well. Affected file lib/silcclient/idlist.c.
642 * Fixed the client library to correctly remove the client
643 from all channels when the client entry is being destroyed.
644 Affected file lib/silcclient/client_notify.c, command.c.
646 * Added auto-nicking support to the client library. If the
647 applicatio now sets client->nickname it will be sent to the
648 server after connecting by the library. This way for example
649 SILCNICK (or IRCNICK) environment variables will have effect
650 and always change the nickname automatically to whatever
651 it is wanted. Affected file lib/silcclient/client.[ch].
653 * Renamed silc_server_command_bad_chars to the
654 silc_server_name_bad_chars and moved it to the
655 silcd/server_util.[ch]. Added also new function
656 silc_server_name_modify_bad to return nickname that
657 includes bad characters as new nickname without those
658 bad characters. This check and modify is now used in
659 silc_server_new_client when the username is initially set
660 as nickname, so it must be checked to be valid nickname.
661 Affected file silcd/packet_receive.c.
663 * The nickname length is now taken from the packet for real
664 and not trusted to strlen() since it clearly can return
665 wrong length for nickname including bad characters. This
666 also applies to channel names. Affected file silcd/command.c.
668 * Removed the lib/silcsilm/modules directory. Modules are now
669 compiled into the lib/silcsim. Fixed the copying of the
670 modules to follow symbolic links in Makefile.am.pre.
672 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
674 * Fixed silc_string_regexify list creation. Fixes bugs with
675 BAN and INVITE commands in server. The affected file is
676 lib/silcutil/unix/silcunixutil.c.
678 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
680 * Removed the command destructor entirely from the server's
681 command and command reply routines. It is not needed, and
682 its usage was buggy and caused crashes. Affected files are
683 silcd/command[_reply].[ch].
685 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
687 * Cancel protocol and NULL sock->protocol if timeout
688 occurred during protocol. Affected file silcd/server.c.
690 * Cancel protocol timeouts always before calling the final
691 callback, to assure that after final callback is called
692 no other state will be called for the protocol anymore.
693 Affected file silcd/protocol.c.
695 * Print error log if incoming connection configuration could
696 not be found. Affected file silcd/server.c.
698 * Fixed JOIN command to correctly save the founder mode
699 to the client on normal SILC server, when the channel
700 was created by the router. Affected file silcd/command.c.
702 * Fixed LIST command (hopefully) to send correct reply
703 packets. Affected file silcd/command.c.
705 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
707 * The silc_packet_receive_process now returns FALSE if the
708 read data was invalid packet, and TRUE if it was ok.
710 The server now checks that if unauthenticated connection
711 sends data and its processing fails the server will close
712 the connection since it could be a malicious flooder.
714 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
716 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
718 * Make sure the warning about error opening a log file is
719 printed only once and not everytime it fails (produces
720 too much useless log). Affected file lib/silcutil/silclog.c.
722 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
724 * Made the silc_server_daemonise() function more readable.
725 Affected file silcd/server.c.
727 * Pid file is now optional, the user may comment it out from
728 the config file. Removed define SILC_SERVER_PID_FILE, we
729 don't need a default any longer. Affected file
730 configure.in.pre, lib/Makefile.am.pre.
732 * Make some use of the pid file. The server now dies at startup
733 if it detects a valid pid file on his path. The server would
734 die anyway in this circumstance, because of the bind() failure.
735 Affected file silcd/silcd.c.
737 * No longer compiling lib/dotconf.
739 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
741 * Fixed JOIN command parsing not to crash. Affected file
742 lib/silcclient/command.c.
744 * Fied the NICK_CHANGE notify to add the new client entry
745 even it is resolved. This removes an <[unknown]> nick
746 thingy bug in the client. Affected file is
747 lib/silcclient/client_notify.c.
749 * Do not try to allocate 0 bytes (efence does not like it)
750 in lib/silccore/silccomand.c when encoding payload.
752 * Do not take IRCNICK as nickname in Irssi SILC client since
753 it is not possible to set nickname before hand connecting
754 the server (TODO has an entry about adding auto-nicking
757 * Changed the silc_server_command_pending to check whether
758 there already exists an pending entry with the specified
759 command, command identifier and pending callback. This is
760 to fix IDENTIFY and WHOIS related crashes that may register
761 multiple pending commands with same identifier. Affected
762 file silcd/command.c.
764 * Fixed the server to reconnect to the router even if it
765 was already reconnecting and EOF was received. This to
766 fix a possibility that the server wouldn't ever try to
767 auto-reconnect to the router. Affected file silcd/server.c.
769 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
771 * Fixed the server's password authentication to use the
772 length of the locally saved password, and not the one
773 sent in the packet. Affected file silcd/protocol.c.
775 * Fixed same password authentication problem in the
776 Authentication Payload handling routines in
777 lib/silccore/silcauth.c.
779 * Yet another password authentication problem fixed with
780 channel password handling in silcd/command.c.
782 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
784 * If first character of string in silc_parse_userfqdn is '@'
785 then do not parse it. Affected file is
786 lib/silcutil/silcutil.c.
788 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
790 * Fixed minor bug in IDENTIFY command reply sending, which
791 caused various weird problems during JOIN when it was
792 resolving names for users. Affected file silcd/command.c.
794 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
796 * Fixed the IDENTIFY command reply sending to chech better valid
797 clients. It was possible to send incomplete list of replies.
798 Affected file silcd/command.c.
800 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
802 * Added silc_client_command[s]_[un]register functions now to
803 dynamically register the commands in client library. Removed
804 the static table of commands. This allows the client library
805 to call commands without causing the application to know about
806 what commands library has called.
808 Removed the INFO command reply kludge to detect when the command
809 was called by library. Now library use its own command reply
810 function for INFO command.
812 Added function silc_client_command_call to call a command.
813 Application can use it to call command, not access the structure
816 Now all commands that are sent by the client library (not
817 explicitly sent by application) use own command reply functions.
819 Affected files around lib/silcclient/ and in
820 irssi/src/silc/core/.
822 * Fixed the WHOIS command reply sending to chech better valid
823 clients. It was possible to send incomplete list of replies.
825 Fixed the WHOIS and IDENTIFY to send the request to router
826 if normal server did not do it and did not find any results.
828 Affected file silcd/command.c.
830 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
832 * Moved the internal data from SilcClient context into its
833 own file, not accesible to application. Affected files
834 lib/silcclient/client.h and lib/silcclient/client_internal.h,
835 and other files in client library.
837 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
839 * Added doc/examples installation target in Makefile.am.pre.
842 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
844 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
845 commands the found client entry will be removed from the
846 cache, after notifying application about the error. Affected
847 file lib/silcclient/command_reply.c.
849 * Changed the /MSG to check for exact nickname user gave, and
850 not let `nick' match `nick@host' if it is only one found. Now,
851 user must type the exact nickname (like nick@host2) even if
852 there are no more than one same nicks found. This is to avoid
853 a possibility of sending nickname to wrong nickname since
854 `nick' could match `nick@host'. Affected file is
855 irssi/src/core/silc-servers.c.
857 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
859 * Do not print "you are now server operator" or similar when
860 giving /away command. Affected files are
861 irssi/src/silc/core/client_ops.c, silc-servers.h.
863 * Made the silc_server_command_pending_error_check to send
864 the same command reply payload it received back to the
865 original sender of the command. This way all arguments
866 that was received by the server will be received by the
867 client too. Affected file silcd/command.c.
869 * Added the silc_idcache_add to return the created cache entry
870 to a pointer. Affected file lib/silccore/silcidcache.[ch].
872 * Add global clients to expire if they are not on any channel.
873 This is because normal server will never know if they signoff
874 if they are not on any channel. The cache expiry will take
875 case of these entries. This is done by normal servers only.
876 The affected files are silcd/command_reply.c,
877 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
879 * If server receives invalid ID notification for WHOIS or
880 IDENTIFY and the ID exists in the lists, it is removed.
881 Affected file silcd/command_reply.c.
883 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
884 in client then client entry that it matches is searched and
885 the nickname is printed on the screen for user. Affected
886 file irssi/src/silc/core/client_ops.c.
888 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
890 * Use cache entry expire time in the LIST command reply to
891 purge old entries from the cache after the LIST command
892 reply has been received. This way we don't have non-existent
893 entries in the cache for too long. Affected file is
894 silcd/command_reply.c.
896 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
898 * If we are normal server, and we've not resolved client info
899 in WHOIS or IDENTIFY from router, and it is global client,
900 we'll check whether it is on some channel. If it is not
901 then we cannot be sure about its validity and will resolve it
902 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
903 file silcd/command.c.
905 * Search channel by name (if possible) rather than by ID
906 in IDENTIFY command's command reply. Affected file is
907 silcd/command_reply.c.
909 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
911 * Distribute to the channel passphrase in CMODE_CHANGE notify.
912 Updated specs and implemented it. Affected file silcd/command.c,
913 silcd/packet_send.c and silcd/packet_receive.c.
915 * Implemented the <founder auth> payload handling in the JOIN
916 command. If provided all conditions for channel joining
917 except requirement to provide correct passphrase can be
918 overrided by the channel founder. Updated the protocol specs.
919 Affected file silcd/command.c.
921 Added support for founder auth in JOIN command in client
922 library. Fixed the parsing of the JOIN command now to support
923 all options as they should be. The affected file is
924 lib/silcclient/command.c.
926 * Optimized the WHOIS and IDENTIFY commands to send the request
927 to router only if it includes nicknames or other names. If
928 they include only IDs then check the local cache first before
929 routing. Affected file is silcd/command.c.
931 * Added channels topic announcements. Affected file is
932 silcd/packet_receive.c and silcd/server.c.
934 * Fixed the silc_server_send_notify_topic_set to really destine
935 the packet to channel. Affected file silcd/packet_send.c.
937 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
938 library. Affected file lib/silcclient/client_notify.c.
940 * Added UMODE announcements. Affected file silcd/server.c.
942 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
944 * Memory leak fixes in:
946 lib/silcutil/silcsockconn.c
947 lib/silcske/silcske.c
950 lib/silccrypt/silcpkcs.c
951 lib/silccore/silccommand.c
952 lib/silccore/silcidcache.c
957 * ROBOdoc documented the lib/silcske/groups.h file and a
958 bit changed the interface for better.
960 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
962 * Update the client entry context in the ID cache after
963 nick change. Affected file lib/silcclient/command.c.
964 Fixes the CUMODE command when regaining founder privileges,
965 and a little WHOIS problem.
967 * Fixed silc_net_gethostbyname to correctly call the
968 inet_ntop. Affected file lib/silcutil/silcnet.c.
970 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
972 * Added IPv6 support checking to the configure.in.pre, added
973 also --enable-ipv6 option to override the check. Affected
974 file configure.in.pre.
976 * The silc_thread_create now calls the start function
977 directly if threads support is not compiled in. Removes
978 ugly #ifdef's from generic code. Affected files are
979 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
981 * Added silc_net_gethostby[name/addr]_async to asynchronously
982 resolve. Affected files are lib/silcutil/silcnet.[ch].
984 * Added support for rendering IPv6 based server, client and
985 channel IDs. Affected file lib/silcutil/silcutil.c.
987 * Added support for creating IPv6 based server IDs. Affected
988 file is silcd/serverid.c.
990 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
992 * Added silc_net_gethostby[addr/name] into the
993 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
994 routines. Added silc_net_is_ip[4/6]. Affected file is
995 lib/silcutil/unix/silcunixnet.c. All routines that take
996 address as argument now supports both IPv4 and IPv6 addresses.
998 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1000 * Fixed LIST command reply sending in server. Affected file
1003 * Server now sends the kicker's client ID in the KICK notify
1004 to the kicked client. Affected file silcd/command.c.
1006 * The client library now parses the kickers client ID and
1007 UI displays it. Affected files lib/silcclient/client_notify.c
1008 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1010 * Made all payload parsing function prototypes consistent.
1011 They all take now const unsigned char * and uint32 pair as
1012 the payload data instead of SilcBuffer. Changes all around
1013 the source tree. Other unsigned char* -> const unsigned char*
1014 changes around the tree as well.
1016 * Optimized SFTP client and server packet sending not to
1017 allocate new buffer for each packet but to recycle the
1018 first allocated buffer. Affected files are
1019 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1021 * Optimized the SFTP client to use SilcList instead of
1022 SilcDList for requests, because it is faster. Affected file
1023 is lib/silcsftp/sftp_client.c.
1025 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1026 into lib/silccore/silcid.[ch].
1028 Renamed silcpayload.[ch] into silcargument.[ch].
1030 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1032 * If client entry is deleted with active key agreement
1033 session, abort the session.
1035 The silc_client_abort_key_agreement now calls the completion
1036 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1038 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1041 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1043 * Don't use __restrict in older GCC's. Affected file is
1044 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1046 * silc_net_localhost now attempts to reverse lookup the
1047 IP/hostname. Affected file lib/silcutil/silcnet.c.
1049 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1050 command. It can be used to gain founder privileges at
1051 the same time when joining the channel.
1053 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1054 kicker's client ID as well. Updated protocol specs.
1056 Defined that the server must send SILC_COMMAND_IDENTIFY
1057 command reply with error status to client who sent
1058 private message with invalid client ID.
1060 Updated the protocol specification.
1062 * Added silc_server_send_command_reply to send any
1063 command reply. Affected file silcd/packet_send.[ch].
1065 * Added silc_id_payload_encode_data to encode ID payload
1066 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1068 * The server now send IDENTIFY command reply with error
1069 status if client ID in private message is invalid. Affected
1070 file silcd/packet_receive.c.
1072 * Save the server key file with server's IP address in
1073 the filename instead of hostname. The affected file is
1074 irssi/src/silc/core/client_ops.c.
1076 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1078 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1081 * Added libtool support for compiling shared objects in
1082 lib/silcsim. Affected file configure.in.pre and
1083 lib/silcsim/Makefile.am. Original patch by cras.
1085 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1087 * Pid file configuration, and server's config file fixes
1088 patch by toma. Updated CREDITS file.
1090 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1092 * Fixed silc_client_channel_message to not try to decrypt
1093 the message twice if it resolved the destination client
1094 information. This could cause of dropping one channel
1095 message. Affected file lib/silcclient/client_channel.c.
1097 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1099 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1100 lib/silcclient/client.c. This function is used when the SILC
1101 Client is run under some other scheduler, or event loop or
1102 main loop. On GUI applications, for example this may be
1103 desired to used to run the client under the GUI application's
1104 main loop. Typically the GUI application would register an
1105 idle task that calls this function multiple times in a second
1106 to quickly process the SILC specific data.
1108 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1110 * Fixed silc_server_drop() for dropping the supplementary
1111 groups as well, this could cause a security hole on some
1114 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1116 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1119 * Write PID file after dropping privileges. Added -F option
1120 to run server on foreground. A patch by debolaz.
1121 Affected files silcd/server.c, silcd/silcd.c.
1123 * Fixed MOTD to return the MOTD file server name. Affected
1124 file silcd/command.c.
1126 * Added INFO command reply handling to the Irssi SILC Client.
1127 Affected file irssi/src/silc/core/client_ops.c.
1129 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1131 * Fixed the silc_idcache_list_* routines to really support
1132 the dynamic list. Fixes a crash. Affected file is
1133 lib/silccore/silcidcache.c.
1135 * Fixed the LIST command reply to really call LIST command's
1136 pending callbacks. Affected file silcd/command_reply.c.
1138 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1140 * Update conn->local_entry->nickname after giving NICK
1141 command. Affected file lib/silcclient/command.c.
1143 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1145 * Added the [pid] option to the silcd configuration file
1147 Affected files: serverconfig.[ch] and silcd.c
1149 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1151 * Save fingerprint in WHOIS command reply in server.
1152 Affected file silcd/command_reply.c.
1154 * Fixed NICK commands pending callback registration.
1155 Affected file lib/silcclient/command.c.
1157 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1159 * Use ++server->cmd_ident when sending commands in server,
1160 instead of random number. Affected file silcd/command.c.
1162 * Fixed GETKEY command reply to call actually GETKEY pending
1163 command callbacks. Affected file silcd/command_reply.c.
1165 * A bit stricter check for nicknames. Check for same nickname
1166 in NICK command also. Affected file silcd/command.c.
1168 * Do not call INFO command everytime client ID changes, only
1169 during first connecting. Affected file lib/silcclient/client.c.
1171 * Set the new nickname only after successful command reply for
1172 NICK command is returned by server. Affected file
1173 lib/silcclient/command.c.
1175 * Remove nicknames from nicklist during server_signoff notify.
1176 Should fix /NAMES bit more. The affected file is
1177 irssi/src/silc/core/silc-channels.c.
1179 * Added `fingerprint' field to the SilcIDListData in the
1180 silcd/idlist.h to hold the fingerprint of the client's
1183 Send the fingerprint of the client's public key in WHOIS
1186 Affected files silcd/command.c, and silcd/idlist.[ch].
1188 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1189 create fingerprint from given data.
1191 * Show the fingerprint of the client's public key in WHOIS.
1192 Affected files irssi/src/module-formats.[ch] and
1193 irssi/src/silc/core/client_ops.c.
1195 * Format the multiple same nicknames also during JOIN and
1196 NICK_CHANGE notifys. Affected file is
1197 lib/silcclient/client_notify.c.
1199 * Do not print error on screen for invalid private message
1200 payload since it can come if someone is sending private
1201 messages with wrong key. Affected file
1202 lib/silccore/silcprivate.c.
1204 * Fixed multiple concurrent /PING crash. Affected file
1205 lib/silcclient/command.c.
1207 * Changed the wrong ID encoding. All IP addresses must be
1208 in MSB first order in encoded format. They were encoded
1209 wrong and was in LSB format. Affected files are
1210 silcd/serverid.c, lib/silcutil/silcutil.c.
1212 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1214 * Call the `connect' client operation through the scheduler
1215 in case of error. Affected file lib/silcclient/client.c.
1217 * Call the `failure' client operation even if the error
1218 occurred locally during a protocol. Affected file is
1219 lib/silcclient/protocol.c.
1221 * Added support of sending LIST command to router from normal
1222 server. This way normal server can get list of all channels
1223 in the network too. Fixed the channel list sending in the
1224 server too. Affected files are silcd/command.c, and
1225 silcd/command_reply.[ch].
1227 * Added silc_server_update_channels_by_server and
1228 silc_server_remove_channels_by_server. They are used during
1229 disconnection of primary router and in backup router protocol.
1230 Affected file silcd/server_util.[ch], silcd/server.c and
1231 silcd/server_backup.c.
1233 * Fixed channel adding to global list in IDENTIFY command
1234 reply in server. Affected file silcd/command_reply.c.
1236 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1238 * If the incoming packet type is REKEY or REKEY_DONE process
1239 that packet always synchronously. Fixes yet another MAC
1240 failed error on slow (dialup) connections. Affected file
1241 lib/silcclient/client.c and silcd/server.c.
1243 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1245 * Call check_version SKE callback for initiator too. Affected
1246 file lib/silcske/silcske.c.
1248 * Implemented fix for security hole found in the SKE that was
1249 fixed in the specification few days back; the initiator's
1250 public key is now added to the HASH value computation.
1251 Added backwards support for the old way of doing it too, for
1252 old clients and old servers. Affected file is
1253 lib/silcske/silcske.c.
1255 * Enabled mutual authentication by default in SKE. If initiator
1256 is not providing mutual authentication the responder will
1257 force it. This will provide the proof of posession of the
1258 private key for responder. The affected files are
1259 lib/silcclient/protocol.c and silcd/protocol.c.
1261 * Do not cache anymore the server's public key during SKE.
1262 We do mutual authentication so the proof of posession of
1263 private key is done, and if the server is authenticated in
1264 conn auth protocol with public key we must have the public
1265 key already. Affected file silcd/protocol.c.
1267 * Added new global debug variable: silc_debug_hexdump. If
1268 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1269 file lib/silcutil/silclog.[ch].
1271 * Fixed compilation warning due to char * -> const char *.
1272 Affected files lib/silcutil/silcnet.h, and
1273 lib/silccore/silcauth.[ch].
1275 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1277 * Fixed CMODE command when new channel key was created. If
1278 the creation failed the old key was removed. Next time giving
1279 same command would crash the server since the old key was
1280 freed already. Affected file silcd/command.c.
1282 * Fixed the silc_server_announce_get_channels to not crash
1283 on reconnect. Affected file silcd/server.c.
1285 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1287 * Added silc_log_set_debug_string function to set a regex
1288 string to match for debug output. Only the function names,
1289 or filenames matching the given debug string is actually
1290 printed. This way it is possible to filter out those debug
1291 strings that user is not interested in.
1293 Fixed a bug in silc_string_regexify.
1295 Affected files lib/silcutil/silclog.[ch], and
1296 lib/silcutil/unix/silcunixutil.c.
1298 * Changed the -d options in both server and Irssi SILC client
1299 to take the debug string as argument. Affected files
1300 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1302 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1304 * Added silc_hash_babbleprint to create a Bubble Babble
1305 Encoded fingerprint. The encoding is developed by Antti
1306 Huima (draft-huima-babble-01.txt), and it creates human
1307 readable strings out of binary data. Affected file
1308 lib/silccrypt/silchash.[ch].
1310 * Print the babble print now in addition of fingerprint as well
1311 in Irssi SILC client. Affected files are
1312 irssi/src/fe-common/silc/module-formats.[ch],
1313 irssi/src/fe-common/silc/core/client_ops.c.
1315 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1317 * Fixed a security problem found in SKE. The initiator's
1318 public key too is now added to the HASH hash value creation
1319 which is signed by the responder to create the SIGN value.
1320 This will prevent anyone in the middle to lie to the responder
1321 about the initiator's public key. If this is done now, the
1322 man in the middle will get caught. Updated the protocol
1325 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1327 * Better installation directory handling. Configure module
1328 paths and other paths automatically to example_silc* files
1329 in doc/. A patch by toma.
1331 * Fixed compiler warning from MPI library, and from SILC RNG.
1334 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1335 It can be configured with ./configure. A patch by toma.
1337 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1339 * Find correct make to use in prepare-clean. A patch by
1340 toma. Affected file prepare-clean.
1342 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1344 * Added irssi variables use_auto_addr, auto_bind_ip,
1345 auto_bind_port and auto_public_ip.
1347 * Changed the interface for silc_client_send_key_agreement
1348 in lib/silcclient/silcapi.h
1352 irssi/src/silc/core/silc-core.c
1354 lib/silcclient/silcapi.h
1355 irssi/src/silc/core/silc-channels.c
1356 lib/silcclient/client_keyagr.c
1359 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1361 * Added silc_pkcs_public_key_compare to compare two
1362 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1364 * Check that the client who set the founder mode on the
1365 channel is the same client that is giving the founder
1366 mode to itself. It is done by comparing the saved public
1367 key (it is saved even in the authentication is passphrase).
1368 Affected file silcd/command.c.
1370 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1372 * Do not process packet for disconnected socket connection.
1373 Affected file lib/silccore/silcpacket.c.
1375 * Process the DISCONNECT packet through scheduler in the
1376 client library. Affected file lib/silcclient/client.c.
1378 * Fixed the silc_client_packet_parse to not to increase
1379 the packet sequence number if the conn->sock and the
1380 current socket connection is not same. This can happen
1381 for example during key agreement when the conn includes
1382 multiple socket connections (listeners). Affected file
1383 lib/silcclient/client.c.
1385 * The sender of the file transfer request now provides also
1386 the pointer (listener) for the key exchange protocol. If
1387 the listener cannot be created then it sends empty key
1388 agreement and lets the receiver provide the listener.
1390 Added `local_ip' and `local_port' arguments to the
1391 silc_client_file_send. If they are provided they are used,
1392 if not then it will attempt to find local IP address, if
1393 not found or bind fails then the remote client will provide
1396 Affected files are lib/silcclient/client_ftp.c and
1397 lib/silcclient/silcapi.h.
1399 * Extended the FILE SEND command to support defining the
1400 local IP and port for key exchange listener. They are
1401 optional. Affected file irssi/src/silc/core/silc-servers.c.
1403 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1405 * Defined to WHOIS command reply the sending of fingerprint
1406 of the client's public key (if the proof of posession of the
1407 corresponding private key is verified by the server).
1408 Updated to the protocol specification.
1410 * Added support of receiving the client's public key's
1411 fingerprint in command reply in client library. Affected
1412 file is lib/silcclient/command_reply.c, and
1413 lib/silcclient/idlist.[ch].
1415 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Do not send over 128 chars long nickname to the server
1418 in NICK command. Affected file lib/silcclient/command.c.
1420 * Do not send over 256 chars long channel names to the server
1421 in JOIN command. Affected file lib/silcclient/command.c.
1423 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1425 * Assure that silc_server_close_connection cannot be called
1426 twice for same socket context. Affected file is
1429 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1431 * Send error message to application if opening file for
1432 writing during file transfer fails. Affected file is
1433 lib/silcclient/client_ftp.c.
1435 Remove all file transfer sessions for a client that we're
1436 removing from ID cache.
1438 Affected file is lib/silcclient/client_ftp.c.
1440 * Fixed silc_net_addr2bin to return correct address. Affected
1441 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1443 * Fixed file transfer session removing on signoff notify.
1444 Affected file irssi/src/silc/core/silc-servers.c.
1446 * Added the SilcClientFileError to be returned in the monitor
1447 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1448 Affected file lib/silcclient/silcapi.h.
1450 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1452 * Fixed a crash in silc_client_ftp_free_sessions and
1453 silc_client_ftp_session_free_client. Affected file
1454 lib/silcclient/client_ftp.c.
1456 * Added `disabled' field in the SilcChannelEntry in the server
1457 to indicate if the server entry is disabled. Affected file
1458 silcd/idlist.h, silcd/command[_reply].c.

1467 * Fixed a crash in client resolving in client_prvmsg.c in
1468 client library. Affected file lib/silcclient/client_prvmsg.c.
1470 * Do not actually remove the client directly from ID cache
1471 during SERVER_SIGNOFF, but invalidate it. This way we
1472 preserve the WHOWAS info for the client. Affected file
1473 silcd/server_util.c.
1475 * Fixed SERVER_SIGNOFF notify handling in the server. The
1476 server is now able to process incoming SERVER_SIGNOFF notify
1477 for a server that it doesn't even know about. It will remove
1478 the clients provided in the notify. Affected file
1479 silcd/packet_receive.c.
1481 * Check for partial packet in data queue after every packet that
1482 was found from the queue. Return and wait for more data if
1483 there is partial data in queue. Affected file is
1484 lib/silccore/silcpacket.c.
1486 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1491 Affected files lib/silcclient/silcapi.h and
1492 lib/silcclient/client_ftp.c.
1494 * Check that newsize in silc_buffer_realloc is larger than
1495 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1497 * Added better monitor of file transfers. It now monitors
1498 key agreement protocol during the file transfer too. Added
1499 error reporting too. Affected files
1500 irssi/src/silc/core/silc-servers.c,
1501 irssi/src/fe-common/silc/module-formats.[ch].
1503 * Wrote a help file for FILE command.
1505 * Added silc_rng_global_get_byte_fast to get not-so-secure
1506 random data as fast as possible. Random data is read from
1507 /dev/urandom if available and from the SILC RNG if not
1508 available. It is used in padding generation. Affected file
1509 lib/silccrypt/silcrng.[ch].
1511 * All packets in client library are now processed synchronously.
1512 Optimized packet processing a lot. Affected file
1513 lib/silcclient/client.c.
1515 * All server connection packets are processing synchronously
1516 now in server, to optimize packet processing. Affected file
1519 * Include files are installed now only in Toolkit distribution
1520 if make install is given. Affected files: all Makefile.am's.
1522 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1524 * Assure that silc_client_notify_by_server_resolve does not
1525 resolve the client information multiple times. If it cannot
1526 be found by the first it cannot be found at all. Affected
1527 file lib/silcclient/client_notify.c.
1529 * Fixed WHOWAS command reply calling. Affected file
1530 lib/silcclient/command_reply.c.
1532 * Removed all references to silc_idlist_get_client from the
1533 Irssi SILC client since that call is internal call used by
1534 the library. The Irssi SILC client will use now client
1535 retrieval functions found in silcapi.h.
1537 * Fixed a bug in resolving nickname info before sending
1538 private message. It used freed memory. Affected file
1539 irssi/src/silc/core/silc-servers.c.
1541 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1543 * Assure my_channels statistics cannot go negative in server.
1544 Affected files silcd/server.c, silcd/server_util.c.

1560 * Added silc_net_localip to return local host's IP address.
1561 Affected file lib/silcutil/silcnet.[ch].
1563 * If key exchange or rekey protocol is active for a connection
1564 parse all packets syncronously since there might be packets
1565 in packet queue that we are not able to process without first
1566 processing packets before them. Affected file silcd/server,
1567 lib/silcclient/client.c.
1569 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1570 whether library should continue processing the packet.
1571 Affected file lib/silccore/silcpacket.h.

1640 Affected file silcd/command.c.
1642 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1644 * Call the silc_server_udpate_servers_by_server in the
1645 primary router that comes back online in the backup resuming
1646 protocol. Otherwise it routes packets wrong. Affected file
1647 silcd/server_util.[ch], silcd/server_backup.c.
1649 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1651 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1652 lib/silcutil/silcbuffmt.[ch].
1654 * Redefined the SILC packet header to include the padding
1655 length. Affected file lib/silccore/silcpacket.[ch].
1657 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1658 length for maximum padding up to 128 bytes). Affected
1659 file lib/silccore/silcpacket.h.
1661 * Removed all backwards support for old 0.5.x MAC thingies.
1662 The SILC packet header change makes it impossible to be
1663 backwards compatible.
1665 * Send the ENDING packet with timeout in the backup resuming
1666 protocol. This is to assure that all routers has connected
1667 to the primary router. Affected file silcd/server_backup.c.
1669 * Changed the RNG to take the first IV from random data. It
1670 used to take it from zero actually. Changed the RNG also
1671 to use /dev/urandom during session. /dev/random is used
1672 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1674 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1676 * Changed the SILC packet header to have the first two bytes
1677 (the packet length) encrypted. Affected files aroung the
1678 code tree, lib/silccore/silcpacket.[ch]. Removed the
1679 SilcPacketCheckDecrypt callback. It is not needed anymore
1680 since the silc_packet_receive_process will determine now
1681 whether the packet is normal or special.
1683 * Implemented the unidirectional MAC keys. Affected files
1684 lib/silcske/silcske.c, silcd/protocol.c and
1685 lib/silcclient/protocol.c.
1687 * Implemented the packet sequence number to the MAC computation.
1688 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1689 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1690 lib/silcclient/protocol.c.
1692 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1694 * Allow backup router to announce servers. All servers
1695 announced by backup router are added to the global list
1696 automatically. Update hte server's socket to our primary
1697 router also when backup router announces a server.
1698 Affected file silcd/packet_receive.c.
1700 * Do not update the client->router in the function
1701 silc_server_udpate_clients_by_server if the client is on
1702 global list. We might fail to find any specific server
1703 for locally connected clients and local cell clients. They
1704 should still use the `from' and not `to' as client->router.
1705 This fixes backup router resuming protocol. Affected file
1706 silcd/server_util.c.
1708 * Decrease channel statistics count only if the channel
1709 deletion worked. Affected files are silcd/server.c and
1710 silcd/server_util.c.
1712 * Added silc_server_update_servers_by_server to update origin
1713 of all server entries. Used during backup router protocol.
1714 Affected files silcd/server_util.[ch], silcd/server.c. and
1715 silcd/backup_router.c.
1717 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1718 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1719 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1720 lib/silccrypt/silchmac.c.
1722 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1724 * Assure that router cannot reroute the same channel message
1725 to the sender. Affected file silcd/packet_receive.c.
1727 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1729 * Made better checks that the channel message is not sent
1730 to the router it came from. Affected file is
1731 silcd/packet_send.c. Fixed memory leak too.
1733 * Announce informations for incoming router connection, but
1734 only after checking if it is replaced by backup router.
1735 Affected file silcd/packet_receive.c.
1737 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1739 * Fixed the backup resuming protocol to work in multiple
1740 router environment. Affected file silcd/server_backup.c.
1742 * Route packet only to one router in the function
1743 silc_server_packet_send_to_channel. Affected file is
1744 silcd/packet_send.c.
1746 * Fixed silc_server_send_notify_dest to set the broadcast
1747 flag. Fixed the silc_server_send_notify_topic to actually
1748 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1749 Affected file silcd/packet_send.c.
1751 * Changed the SFTP Filesystem interface. Changed the
1752 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1753 the filesystem operation function. The SilcSFTPFilesystem
1754 is now a context that is allocated by all filesystem allocation
1755 functions and it already includes the operations structure
1756 and filesystem specific context. It is given as argument
1757 now to the silc_sftp_server_start. This made the interface
1758 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1759 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1761 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1763 * Changed the backup router adding and getting interfaces
1764 in the server. The router that will be replaced by the
1765 specified backup router is now sent as argument. Affected
1766 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1769 * Added silc_net_addr2bin_ne to return the binary form of
1770 the IP address in network byte order. Affected files
1771 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1773 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1775 * Check for existing server ID in silc_server_new_server
1776 and in silc_server_connect_to_router_final and remove the
1777 old entry if it exists. Affected file silcd/packet_receive.c,
1780 * Send the channel message always to only one router, either
1781 in upstream or downstream. Affected file is
1782 silcd/packet_send.c.
1784 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1786 * Wrote the definition of the backup resuming protocol to the
1787 protocol specification.
1789 * Removed one redundant channel key generation from normal
1790 server during joining procedure. Removed one redundant
1791 channel key sending from server to router during joining
1792 procedure. Affected file silcd/command.c.
1794 * Made minor bugfixes to the backup router resuming protocol.
1795 Affected file silcd/server_backup.c, server.c.
1797 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1799 * Added --disable-asm configuration option. Affected files
1800 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1803 * Implemented the backup resuming protocol that is used to
1804 resume the primary router position in the cell after the
1805 primary router comes back online. Affected files
1806 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1807 and silcd/server_util.[ch].
1809 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1811 * Sleep two (2) seconds after sending QUIT command to server.
1812 Affected file lib/silcclient/command.c.
1814 * Assure that if outgoing data buffer is pending do not force
1815 send any data. Affected file silcd/packet_send.c.
1817 * Assure that if outgoing data buffer is pending do not force
1818 send any data. Affected file lib/silcclient/client.c.
1820 * Implemented the backup router support when the primary router
1821 goes down. The servers and routers can now use the backup
1822 router as new primary router without loosing connectivity.
1824 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1826 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1827 in the server to indicate disabled entry. All data read
1828 from the connection will be ignored and no data is sent
1829 for entry that is disabled. Affected files are
1830 silcd/idlist.h, silcd/server.c.
1832 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1834 * Created SFTP client and server test programs in the
1835 lib/silcsftp/tests directory.
1837 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1839 * Implemented memory filesystem (virtual filesystem) for
1840 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1843 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1845 * Implemented the SFTP (SSH File Transfer Protocol) to the
1846 lib/silcsftp. It includes SFTP client and SFTP server
1849 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1851 * Moved lib/silccore/silcprotocol.[ch] to the
1852 lib/silcutil library.
1854 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1855 take variable argument list pointer as argument. Affected
1856 file lib/silcutil/silcbuffmt.[ch].
1858 * Added silc_buffer_set function that is used to set data
1859 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1860 Affected file lib/silcutil/silcbuffer.h.
1862 * Changed various routines in the core library to use the new
1863 silc_buffer_set instead of allocating new buffer only for
1866 * Added 64-bit value formatting and unformatting support to the
1867 silc_buffer_[un]format routines. Affected file is
1868 lib/silcutil/silcbuffmt.[ch].
1870 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1871 to includes/bitmove.h.
1873 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1875 * Fixed channel user mode saving in client library. Affected
1876 file lib/silcclient/command[_reply].c.
1878 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1880 * Defined the file transfer to the SILC Protocol. Added
1881 new packet type SILC_PACKET_FTP and defined File Transfer
1882 Payload. The mandatory file transfer protocol is SFTP
1883 (SSH File Transfer Protocol). Affected file in addition
1884 of the internet draft is lib/silccore/silcpacket.h.
1886 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1887 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1888 is used as part of backup router protocol when the primary
1889 router of the cell is back online and wishes to resume
1890 the position as primary router.
1892 * Redefined the MAC generation keys in the protocol. The
1893 same key is not used anymore in both direction. Both
1894 direction will now use different keys for sending and
1895 receiving. This fixes a potential security flaw. This
1896 change causes incompatibilities in the protocol.
1898 * Redefined also the MAC computation from the packet.
1899 An packet sequence number is now added to the MAC
1900 computation. This prevents possible replay attacks against
1901 the protocol. This change too causes incompatibilities
1904 Added `sequence' field to the SilcPacketContext to hold
1905 the current sequence number for the packet.
1907 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1909 * Added `created' field to the SilcIDListData in the file
1910 silcd/idlist.h to indicate the time when the entry was
1913 * Added `created' field to the SilcChannelEntry too. Affected
1914 file silcd/idlist.h.
1916 * Added `creation_time' aguments to all the announcement functions
1917 in the server. If it is provided then only the entries that
1918 was created after the provided time frame are actually
1919 announced. Affected file silcd/server.[ch].
1921 * The protocol says that the Channel ID's IP address must be
1922 based on the router's IP address. Added check for this in
1923 the silc_server_new_channel when processing incoming New Channel
1924 Payload. Affected file silcd/packet_receive.c.
1926 * Print out the correct version with --version in SILC client.
1927 Affected file irssi/src/silc/core/silc-core.c.
1929 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1931 * Fixed WHOWAS command to check for completnes of the client
1932 entry always, not just when the command is coming from client.
1933 Affected file silcd/command.c.
1935 * Added new function silc_server_packet_queue_purge to purge the
1936 outgoing data queue to the network. After the function returns
1937 it is guaranteed that the outgoing packet queue is empty.
1938 Affected file silcd/packet_send.[ch].
1940 * Purge the outgoing packet queue in the rekey protocol's final
1941 callback to assure that all rekey packets go to the network
1942 before quitting the protocol. Affected file silcd/server.c.
1944 * Added silc_client_packet_queue_parse as similar function as
1945 in server to the client library. The affected file is
1946 lib/silcclient/client.c.
1948 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1950 * Splitted silcd/server.c and created silcd/server_util.[ch]
1951 for utility functions.
1953 * Added new socket flag SILC_SF_DISABLED to indicate that the
1954 connection is open but nothing can be sent to or received from
1955 the connection. Affected file lib/silcutil/silsockconn.[ch].
1956 The checking for disabled socket is checked in the low level
1957 silc_socket_write and silc_socket_read functions.
1959 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1961 * Allow only nicknames and channel names that fits into the
1962 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1964 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1966 * When processing JOIN command reply in server check that if
1967 the channel exists in our global list we'll move it the local
1968 list. Affected file silcd/command_reply.c.
1970 * Fixed the check whether client is joined on the channel already
1971 in JOIN command. Affected file lib/silcclient/command.c.
1973 * Fixed the JOIN command reply to check whether the channel
1974 already exists. Affected file lib/silcclient/command_reply.c.
1976 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1978 * Added silc_ske_status_string to map the SKE error numbers
1979 to readable strings. The affected files are
1980 lib/silcske/silcske[_status].[ch].
1982 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1984 * Do not show the private channels on the WHOIS channel list
1985 as it is not allowed by the protocol. The affected file is
1988 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1990 * Assure that the packet length digged from the actual packet
1991 is something sensible in the silc_packet_decrypt_rest_special
1992 in lib/silccrypt/silcpacket.c.
1994 * Free and NULL the allocated pointer in silc_hmac_alloc if
1995 the HMAC allocation fails. The affected file is
1996 lib/silccrypt/silchmac.c.
1998 * Print the selected security properties to the log files in
1999 the server. Affected file silcd/protocol.c.
2001 * Add SKE's reference counter even if calling the completion
2002 callback manually. Otherwise it goes negative, although it
2003 does not cause any problems. The affected file is
2004 lib/silcske/silcske.c.
2006 * Remove the client entry with short timeout after giving the
2007 KILL command. Affected file lib/silcclient/command.c.
2009 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2010 case all found clients are already disconnected (WHOWAS would
2011 found them) in the server. Affected file silcd/command.c.
2013 * Update the last_receive (time of last data received) to be
2014 updated only when received private or channel message so that
2015 the idle time showed in WHOIS makes more sense.
2017 * Added boolean field `valid' in to the SilcClientEntry in the
2018 client library to indicate whether the entry is valid or not.
2019 This fixes the nickname change bug on channel when changing
2020 the nickname to be same than the old (like nick to Nick) the
2021 nickname formatter doesn't set the new nick anymore to Nick@host.
2022 Affected file lib/silcclient/idlist.[ch].
2024 * Now actually fixed the nickname changing on disconnection.
2025 Added new function silc_change_nick to the Irssi SILC Client.
2026 Affected file irssi/src/silc/core/client_ops.c,
2027 irssi/src/silc/core/silc-nicklist.[ch].
2029 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2031 * Check that the public key exists in the GETKEY command before
2032 trying to encode it. Affected file silcd/command.c.
2034 * Print some notifications on received public keys with GETKEY
2035 command in the Irssi SILC Client. Affected files are
2036 irssi/src/fe-common/silc/module-formats.[ch],
2037 irssi/src/silc/core/client_ops.c.
2039 * Use IDENTIFY command to resolve the server information in the
2040 GETKEY command instead of INFO command. Affected file
2041 lib/silcclient/command.c.
2043 * All command reply functions in the client library now calls
2044 the pending command reply callbacks even if an error has
2045 occurred. The server has done this a long time and now it was
2046 time to move the client library to this as well. Now all
2047 errors can be delivered back to the pending command reply
2048 callbacks if necessary. Affected files are
2049 lib/silcclient/command[_reply].[ch].
2051 * Change the nickname on disconnection back to the username
2052 because in reconnect the server will enforce it to it anyway.
2053 Affected file irssi/src/silc/core/silc-servers.c.
2055 * Fixed a config file parsing bug in the Irssi SILC client.
2056 Affected file irssi/src/silc/core/clientconfig.c.
2058 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2060 * When printing the channel mode on JOIN, verify that the
2061 channel key and channel's HMAC are valid. Affected file
2062 irssi/src/silc/core/client_ops.c.
2064 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2066 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2067 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2068 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2070 * Removed channel key rekey task deleting from the function
2071 silc_server_save_channel_key. Affected file silcd/server.c.
2072 Added explicit timeout task context instead that is used to
2073 delete the task if we are registering a new task before the
2074 new task has elapsed.
2076 * When channel key rekey occurs the client library now saves
2077 the old channel key for a short period of time (10 seconds) and
2078 is able to use it in case some is still sending channel
2079 messages encrypted with the old key after the rekey. Affected
2080 file lib/silcclient/[idlist.h|client_channel.c].
2082 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2084 * Added check to the silc_server_new_id_real to not accept
2085 new ID if it is the sender's own ID. Affected file is
2086 silcd/packet_receive.c.
2088 * Assure that we do not announce ourself or the one we've
2089 sending our announcements when we're router and are announcing
2090 servers to our primary router. Affected file silcd/server.c.
2092 * Fixed silc_server_command_identify_check_client to assemble
2093 correct WHOIS packet. It send corrupted WHOIS packet and
2094 caused problem with router to router connections. Affected
2095 file silcd/command.c.
2097 Fixed also silc_server_command_whois_check the same way
2098 as for the IDENTIFY command.
2100 * Added new SilcIDListStatus to the server in the SilcIDListData
2101 structure. The status now includes the current status of
2102 the entry (like registered, resolved etc.). Affected file
2103 silcd/idlist.[ch]. Defined a bunch of different status types
2104 as well. This replaced the old boolean registered field as well.
2106 Added resolve_cmd_ident field to the SilcClientEntry structure
2107 too so that if the entry is for example being resolved so
2108 another command may attach to the same pending command reply
2109 without requiring to resolve the same entry again. This concept
2110 should optimize the WHOIS and the IDENTIFY resolving under
2111 heavy load by taking away unnecessary resolving for entries
2112 that are being resolved already.
2114 Added support for adding multiple pending commands for one
2115 command idenfier. Affected file silcd/command[_reply].[ch].
2117 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2118 before deleting the data. Otherwise the hash table will have
2119 freed data in comparison functions. Affected file is
2120 silcd/command_reply.c.
2122 * Fixed silc_idlist_replace_client_id to add the new entry to
2123 the cache with NULL nickname. Otherwise there will be invalid
2124 memory as the nickname after the nickname is freed. Affected
2125 file silcd/packet_receive.c.
2127 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2128 saved into wrong slots because the previous number of entries
2129 was not taken into account. Affected file silcd/idlist.c.
2130 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2132 * If we are router and we receive JOIN notify to a channel that
2133 does not have any users then notified client is marked as the
2134 channel founder, as it is it. The affected file is
2135 silcd/packet_receive.c
2137 * Added to the extended hash table API's table_del_*ext functions
2138 the destructor as argument too, so that the caller can decide
2139 which destructor to use or whether to use destructor at all.
2140 Affected file lib/silcutil/silchashtable.[ch].
2142 * Fixed ID Cache purging. It actually deleted the entries from
2143 the hash table after the data was freed. The hash table ended
2144 up comparing freed memory. The affected file is
2145 lib/silccore/silcidcache.c.
2147 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2149 * Fixed Irssi SILC client's KILL command's HELP syntax.
2151 * The USERS command now resolves the detailed user information
2152 if the userinfo field is missing. Affected file is
2153 lib/silcclient/command_reply.c.
2155 * Do not print error in silc_file_read if the read file does
2156 not exist. Just silently return NULL. Affected file is
2157 lib/silcutil/silcutil.c.
2159 * Fixed the silc_log_output to not wine about NULL filename
2160 and to not create some bogus " " filename. Affected file is
2161 lib/silcutil/silclog.c.
2163 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2165 * Fixed various printing bugs on the user interface in the
2166 Irssi SILC Client. Minor changes that were forgotten from
2169 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2171 * Fixed the configure.in.pre and the compilation and distribution
2172 environment to support the new autoconf 2.52. That version is
2173 now required to compile the CVS trunk.
2175 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2177 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2178 to generally parse user@fqdn format strings. Affected file
2179 lib/silcutil/silcutil.c.
2181 * Added nickname_format and nickname_force_format fields to the
2182 SilcClientParams structure. The first one defines the format
2183 for the nicknames that the library will enforce if the receives
2184 multiple same nicknames. The second one is boolean value and
2185 can be used to force the library to always enforce the format
2186 to the nicknames regardles whether there are multiple nicknames
2187 or not. This configurable formatting was employed to flexibly
2188 support accessing multiple nicknames from the user interface.
2189 The userinterface can now set the nicknames to what ever format
2190 they prefer. Affected file lib/silcclient/silcapi.h.
2192 Added function silc_client_nickname_format to the file
2193 lib/silcclient/idlist.c. It performs the nickname formatting.
2195 Added new field `hostname´ to the SilcClientEntry context.
2196 It holds the hostname of the client. Affected file is
2197 lib/silcclient/idlist.h.
2199 * Irssi SILC Client sets the nicknames in nick@hostn format.
2200 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2201 irssi/src/silc/core/silc-core.c.
2203 The WHOIS printing now also shows both the real nickname and
2204 the formatted nickname so that user knows how to access the
2205 user if there are multiple same nicknames cached. Affected
2206 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2207 printing formatting too to take the hostname now as a separate
2208 argument. The Affected file is
2209 irssi/src/fe-common/silc/modules-formats.[ch].
2211 * Changed the silc_client_get_clients_local to accept the formatted
2212 nickname as argument. It accepts the real nickname too but the
2213 formatted nickname can be used to find the true entry from
2214 multiple entries. Affected file lib/silcclient/silcapi.h and
2215 lib/silcclient/idlist.c.
2217 * Added nickname_format_parse field to the SilcClientParams.
2218 It is a callback function provided by the application to parse
2219 the nickname out of the formatted nickname string. The library
2220 calls it to get the nickname from the formatted string. Since
2221 the application generally knows better the format of the nickname
2222 string it parses it instead of the library, even though library
2223 encodes the formatted string. If the callback function is not
2224 provided then the library will use the string as is. The
2225 affected file is lib/silcclient/silcapi.h.
2227 * All the nickname strings passed to the client library in
2228 commands are now expected to be formatted nickname strings.
2229 If the command does not support the formatted nickname string
2230 it will assume that the sent string is the actual nickname.
2231 Affected file lib/silcclient/command.c.
2233 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2235 * Added public key authentication support to OPER and SILCOPER
2236 commands in the client library. Affected file is
2237 lib/silcclient/command.c.
2239 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2241 * Changed the get_auth_methdod client operation to be asynchronous.
2242 It can be async if the application resolves the authentication
2243 method from the server during the negotiation. Added new
2244 SilcGetAuthMeth completion callback that the application will
2245 call after resolving the authentication method.
2247 Added function silc_client_request_authentication_method that
2248 the application can use to resolve the authentication method
2249 from the server. Added also SilcConnectionAuthRequest callback
2250 that the library will call after the server has replied. The
2251 application can call this function if it does not know the
2252 current authentication method.
2254 Affected files are lib/silcclient/client.c and
2255 lib/silcclient/silcapi.h.
2257 * The Irssi SILC client now automatically resolves the authentication
2258 method incase any configuration information is not present (and
2259 currently there never is). The affected file is
2260 irssi/src/silc/core/client_ops.c.
2262 * Fixed public key authentication from the client library.
2263 Affected file lib/silcclient/protocol.c. Changed also the
2264 protocol specification about the public key authentication in
2265 the connection authentication protocol. The actual data to be
2266 signed is now computed with a hash function before signing.
2268 * Fixed the public key authentication from the server as well.
2269 Affected file silcd/protocol.c.
2271 * Removed the mlock()'s from the memory allocation routines.
2272 Affected file lib/silcutil/silcmemory.c. The ./configure does
2273 not check anymore for the mlock(). Affected file is
2276 * Fixed USERS command in server to allow the execution of the
2277 command for private and secret channels if the client sending
2278 the command is on the channel. Affected file silcd/command.c.
2280 * Fixed silc_client_get_clients_local to return the clients
2281 count correctly. It could return wrong value. Affected file
2282 lib/silcclient/idlist.c.
2284 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2286 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2287 types. The assembler optimizations seemed not to like 64-bit
2288 data types. The assmebler optimizations thus are now enabled
2289 also for BSD systems as opposed to only enable them for Linux.
2291 * Do not check for threads at all on BSD systems. Affected
2292 file configure.in.pre.
2294 * Removed -n and -h options from the Irssi SILC Client since
2295 they are not used in silc.
2297 * Fixed the prime generation to assure that the first digit
2298 of the generated random number is not zero since our conversion
2299 routines does not like number strings that starts with zero
2300 digit. If zero digit is seen the random number is regenerated.
2301 This caused some corrupted RSA keys when the zero first digit
2302 was met. Affected file lib/silcmath/silcprimegen.c.
2304 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2306 * Fixed WIN32 configuration in the ./configure script.
2307 Fixed to include xti.h on environments that has it.
2308 Patches by Carsten Ilchmann and andrew.
2310 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2312 * Changed the silc_id_create_client_id to be collision
2313 resistant. It is now assured that there cannot be created
2314 two same client ID's. I suspect that some weird bugs in
2315 the server were actually caused by duplicate Client IDs.
2316 Affected file silcd/serverid.[ch]. A router receiving
2317 new ID now also assures and informs the sending server
2318 if the ID caused collision.
2320 * Changed the silc_id_create_channel_id to also assure that
2321 there are no collisions.
2323 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2325 * Statement about ignoring the Mutual Authentication flag when
2326 performing rekey with PFS was a bit misleading. It is ignored
2327 if it was set in the initial negotiation, it cannot be even
2328 set in the rekey. Fixed in the ke-auth draft. Started the
2329 new versions of the protocol drafts in the doc/.
2331 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2333 * Fixed a bug in silc_client_command_identify_save when saving
2334 new channel information. The channel name was no duplicated
2335 and caused crash on exit. Affected file is
2336 lib/silcclient/command_reply.c.
2338 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2340 * Fixed the getkey command handling in the server. Send just
2341 empty OK reply to the sender if the key could not be fetched
2342 (but everything else was ok, like the key just was not available).
2343 Changed the public key parameter to optional in the protocol
2344 specs so that empty OK reply can be sent. Affected file
2347 Added a message to Irssi SILC client to tell to user if the
2348 server did not return a public key.
2350 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2352 * Fixed a channel key regeneration bug. It registered new
2353 timeout tasks exponentially until all system resources were
2354 used. Affected file silcd/server.c.
2356 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2358 * Added the SILC Document generator to the scripts/silcdoc.
2359 It can be used to generate the Toolkit Reference Manual out
2360 of the source tree. Internally it will also use the RoboDoc
2361 generator now imported in util/robodoc.
2363 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2365 * Added couple of return's in rekey protocol if error orccurred
2366 during the protocol. The execution must be terminated.
2367 Affected file silcd/protocol.c. Also, terminate the protocol
2368 always with timeout.
2370 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2372 * The client's Client ID was created initally from the wrong
2373 nickname (it could have been in format nick@host) in the
2374 silc_server_new_client. Affected file silcd/packet_receive.c
2376 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2378 * Added some SILC_LOG_ERROR's to various error conditions
2379 if client could not be added to ID cache. Affected files
2380 silcd/packet_receive.c and silcd/server.c.
2382 * When client's sock->user_data is freed, NULL also the
2383 client->router and client->connection pointers. Added check
2384 for these pointers being NULL to various places around the
2385 code. Affected file silcd/server.c.
2387 * Added client->data.registered == TRUE checks to various
2388 places around the code to assure that unregistered client's
2389 are not handled when it is not allowed. Affected file
2392 * Added `bool registered' fields to all
2393 silc_idlist_[server|client]_get_* routines to indicate whether
2394 the fetched client needs to be registered or not. Affected
2395 file silcd/idlist.[ch].
2397 * Add your own entry as registered to the ID cache in the
2398 server. Affected file server.c.
2400 * Fixed a bug in silc_server_new_server. The SilcServer was
2401 set as the new server's context instead of SilcServerEntry.
2402 This naturally caused some weird bugs.
2404 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2406 * Do not delete the channel rekey task when adding it
2407 for in silc_server_create_channel_key.
2409 * Changed the silc_server_create_channel_key to return
2410 TRUE or FALSE to indicate the success of the channel key
2413 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2415 * Fixed MSVC++ project files and added missing files to
2416 Makefiles under win32/.
2418 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2420 * Do not add TCP_NODELAY flag if the operating system
2421 does not have it defined. Affected files are
2422 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2424 * Fixed buffer overflow from Irssi SILC Client. Affected
2425 file irssi/src/fe-common/core/themes.c.
2427 * Fixed double free in client library in the file
2428 lib/silcclient/client.c when disconnecting from server.
2430 * Applied double free patch from cras to Irssi SILC client.
2431 Affected files irssi/src/core/[modules/expandos].c
2433 * Fixed the disconnection handling to Irssi SILC Client.
2434 The application must call silc_client_close_connection
2435 in ops->connect client operation in case of failure of
2436 the connection. Affected file is
2437 irssi/src/silc/core/client_ops.c.
2439 * Do not set sock->protocol to NULL in the function
2440 silc_client_close_connection after executing the protocol's
2441 final callback since the sock might not be valid anymore.
2442 Affected file lib/silcclient/client.c.
2444 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2446 * Do not enable SILC_THREADS if the linking with libpthread
2447 did not happen. Affected file configure.in.pre.
2449 * Added notion to protocol specification that server must
2450 verify the sent authentication payload with CMODE when
2451 setting the channel founder key. Implemented it to the
2452 server. Affected file silcd/command.c.
2454 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2456 * Added _EXTRA_DIST SILC distribution variable to the
2457 distributions file. It is used to conditionally add extra
2458 files or directories to the specific distribution. Affected
2459 files ./prepare, Makefile.am.pre and distributions.
2461 Removed the `_' from the start of the distribution names.
2464 * Added README.WIN32 for instructions to compile the Toolkit
2467 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2469 * Fixed a double free in disconnection in the server. Affected
2470 file is silcd/server.c.
2472 * Fixed the lib/silcske/groups.c to work now also with GMP
2473 MP library. The string conversion did not work when using
2474 specific base and the base is indicated in the string as well.
2476 * Created win32/ directory which now includes MSVC++ specific
2477 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2478 It will appear only in the toolkit distribution
2480 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2482 * Changed the key material distribution function in case when
2483 the hash output is too short. The data is now concatenated
2484 a bit differently than it used to. Made the change to the
2485 SKE protocol specification.
2487 * Added better GMP detection to configure.in.pre. A patch
2490 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2492 * Fixed a minor bug in SKE that might cause some problem on
2493 some platforms. Affected file lib/silcske/silcske.c.
2495 * Added the cookie checking for initiator in the SKE. It checks
2496 that the responder returns the sent cookie unmodified. The
2497 affected file is lib/silcske/silcske.c. Added new SKE
2498 error type INVALID_COOKIE that can be sent during the
2499 negotiation. Fixed some memory leaks as well.
2501 * Added the "invalid cookie" error message to Irssi SILC client's
2504 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2506 * Added `task_max' field to the SilcClientParams to indicate
2507 the maximum tasks the scheduler can handle. If set to zero,
2508 default values are used. Affected file lib/silcclient/silcapi.h.
2510 * Fixed memory leaks in silc_client_close_connection. Affected
2511 file lib/silcclient/client.c.
2513 * Added silc_client_del_client_entry to client library to free
2514 all memory of given client entry. Affected file is
2515 lib/silcclient/idlist.[ch].
2517 * Added new functions silc_client_del_channel and
2518 silc_client_del_server to delete channel and server entries.
2519 Affected file lib/silcclient/[silcapi.h/idlist.c].
2521 * Removed silc_client_del_client_by_id from silcapi.h.
2523 * Fixed the INFO command to return the server's own info
2524 correctly when querying by Server ID. Affected file is
2527 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2529 * Removed the non-blocking settings in WIN32 code in the
2530 silc_sock_[read/write] and added SleepEx instead. Affected
2531 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2532 of input data is now checked with FIONREAD and ioctlsocket.
2534 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2536 * Call silc_schedule_task_del_by_context in the
2537 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2538 Affected file lib/silccore/silcprotocol.c.
2540 * Call silc_protocol_cancel for active protocols in the
2541 silc_server_close_connection if the funtion
2542 silc_server_free_sock_user_data has not been called.
2543 Affected file silcd/server.c.
2545 * Generic tasks cannot be deleted using the del_by_fd
2546 task deleting function since generic tasks does not match
2547 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2549 * Added a notion to SILCOPER help file that the SILCOPER works
2550 only on router server, not on normal server.
2552 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2554 * Added for WIN32 support for the new scheduler as well.
2555 Affected file lib/silcutil/win32/silcwin32schedule.c.
2557 * Fixed the SHA1 implementation to work on various platforms.
2559 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2561 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2562 API. It is part of the scheduler now. Everything else is
2563 as previously but some functions has changed their names.
2564 Checkout the lib/silcutil/silcschedule.h for the interface.
2565 Updated all applications to use the new interface. Affected
2566 files are lib/silcutil/silcschedule.[ch].
2568 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2570 * Found a bug in the SKE implementation. The HASH value,
2571 specified by the protocol, was not computed correctly. The
2572 public key of the responder was not added to the computation
2573 even though it is mandatory. Affected file lib/silcske/silcske.c.
2574 This unfortunately causes incompatibilities with older
2575 clients and servers.
2577 * Added WIN32 specific network init and uninit functions:
2578 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2579 the Winsock2. Affected file lib/silcutil/silcnet.h and
2580 lib/silcutil/win32/silcwin32net.c.
2582 * Set the socket always to nonblocking mode on WIN32 after
2583 reading data or writing data. Affected file is
2584 lib/silcutil/win32/silcwin32sockconn.c.
2586 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2588 * Fixed various compilation problems under WIN32. Affected
2589 files lib/silcutil/win32/silcwin32thread.c and
2590 lib/silcutil/win32/silcwin32schedule.c.
2592 * Removed all _internal.h #includes from public header
2593 files. Internal headers must never be included from
2596 Removed also the lib/silcske/payload_internal.h file.
2598 * All include files that may be needed (public and some others
2599 included by the public headers) by application developers are
2600 now copied to the ./includes directory. It does not copy any
2601 internal headers. Affected file Makefile.defines.pre and all
2602 Makefile.am's under lib/ and subdirs.
2604 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2606 * Do not change the ~/.silc directory's permissions automatically.
2607 Affected file irssi/src/silc/core/clientutil.c.
2609 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Do not cancel the protocol in silc_server_close_connection
2612 it might cause recursion. Now cancelled in the function
2613 silc_server_free_sock_user_data. Affected file silcd/server.c.
2615 * Fixed the silc_server_remove_clients_by_server to regenerate
2616 the channel keys correctly finally. Added also new function
2617 silc_server_remove_clients_channels to actually do it.
2618 Affected file silcd/server.c.
2620 * Fixed the silc_server_new_channel to not crash by giving
2621 wrong router to the new channel. Affected file is
2622 silcd/packet_receive.c.
2624 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2626 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2627 which is given as argument to the silc_client_alloc now.
2628 It can be used to configure the client and set various parameters
2629 that affect the function of the client.
2631 * The USERS command in server did not check whether the channel
2632 is private or secret. Affected file silcd/command.c.
2634 * Added new argument to the USERS command in protocol specification.
2635 The USERS command now can take the channel name as argument
2636 as well. Added support for this in client and server and
2637 updated the protocol specs.
2639 * Completed the GETKEY command in client. It can be now used
2640 to fetch also servers public key not only some clients.
2641 Affected files lib/silcclient/command[_reply].c.
2643 * Added silc_client_get_server to return server entry by the
2644 server name. Affected files lib/silcclient/silcapi.h and
2647 * Redefined the IDENTIFY command in protocol specification to be
2648 more generic. It now can be used to query information about
2649 any entity in the SILC Network, including clients, servers and
2650 channels. The query may be based either the entity's name
2651 or the ID. Added support for this in both client and server.
2653 Affected files silcd/command.c and lib/silcclient/command.c
2654 and command_reply.c.
2656 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2657 the _from_client and _from_server functions. Affected file
2660 * Added silc_client_get_channel_by_id_resolve to the file
2661 lib/silcclient/silcapi.h to resolve channel information by
2662 its ID. Added also silc_client_get_channel_by_id that
2663 does not resolve it from the server.
2665 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2667 * Added SilcServerEntry context into the client library
2668 to represent one server. The INFO command now allocates
2669 these to save the resolved server info. For now on the
2670 client library will also keep information about servers,
2671 connected and resolved with INFO.
2673 The INFO command now allocates the SilcServerEntry context
2674 and saves the server info there. The COMMAND_REPLY in
2675 the INFO now returns the parameters to application in
2676 same order as defined in the protocol specification.
2678 The entries are cached in the client->server_cache.
2680 * The INFO command is now issued after received the Client ID
2681 from the server. Affected file lib/silcclient/client.c.
2683 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2684 to the application as the mode changer might be server.
2685 It is guaranteed that NULL is not returned anymore to the
2686 application. Affected file lib/silcclient/client_notify.c.
2688 The ID Type is now also passed to the application so that
2689 it can check whether the returned entry is SilcClientEntry
2692 Added new function silc_client_get_server_by_id to return
2693 the server entry by ID. Affected files are the
2694 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2696 * Do not create the channel in the Irssi SILC Client when issuing
2697 the JOIN command but when received the sucessful JOIN command
2698 reply. Otherwise the channel might get created even though we
2699 could not join it. The Affected file is
2700 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2702 * Fixed a channel joining bug in router. The router must also
2703 check the channel modes, invite and ban lists etc. when serving
2704 the JOIN command sent by normal server. Affected file is
2705 silcd/command.c. The router now resolves the client's
2706 information from the server who sent the JOIN command if it
2707 does not know it, and processes the JOIN command only after
2710 * Changed the SilcCommandCb to take new argument; void *context2.
2711 Affected file lib/silccore/silccommand.h
2713 The second argument in the command callbacks in the server now
2714 includes the SilcServerCommandReplyContext if the command was
2715 called as pending command callback from the command reply.
2716 Otherwise it is NULL. When called as pending the status of the
2717 command reply will be checked and if it was erronous the
2718 error will be sent to the original sender of the command.
2719 This way the client always receives the error messages even
2720 though the server was actually the one who received the error
2721 when it resent the command to router, for example. Affected
2722 files silcd/command[_reply].[ch].
2724 * Fixed sending WHOWAS command's error message to client if
2725 the requested client could not be found. It was missing.
2728 * Changed the CMODE and CUMODE commands reply arguments in the
2729 protocol specification. The Channel ID is now sent in both
2730 of the commands to identify the channel. Implemented this
2731 new feature to the client and server. Affected files
2732 lib/silcclient/command_reply.c and silcd/command.c.
2734 * Made better checks for invite and ban lists in the JOIN
2735 command in server. Affected file silcd/command.c.
2737 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2739 * The server now performs the incoming host IP/DNS lookup
2740 using the silc_socket_host_lookup and thus does not block
2741 the server anymore. Affected file silcd/server.c.
2743 * Completed the multi-thread support for SILC Scheduler in
2744 the lib/silcutil/silcschedule.c.
2746 * Fixed the configure.in.pre to detect the pthread correctly
2749 * Fixed a deadlock in silc_task_queue_wakeup in the file
2750 lib/silcutil/silctask.c.
2752 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2754 * Added new function silc_schedule_wakeup that is used in
2755 multi-threaded environment to wakeup the main thread's
2756 schduler. It needs to be used when a thread adds a new task
2757 or removes a task from task queues. After waking up, the
2758 scheduler will detect the task queue changes. If threads
2759 support is not compiled in this function has no effect.
2760 Implemented the wakeup mechanism to both Unix and WIN32
2761 systems. Affected files are lib/silcutil/silcschedule.[ch],
2762 lib/silcutil/unix/silcunixschedule.c and the
2763 lib/silcutil/win32/silcwin32schedule.c.
2765 * Added new function silc_task_queue_wakeup to wakeup the
2766 scheduler by the specified task queue. Affected file
2767 lib/silcutil/silctask.[ch].
2769 * The silc_socket_host_lookup_start now wakes up the scheduler
2770 after adding the timeout task. Affected file is
2771 lib/silcutil/silcsockconn.c.
2773 * The silc_socket_host_lookup is synchronous now if the threads
2774 support is not compiled in. However, the callback is still
2775 called asyncronously through the scheduler, anyway. Affected
2776 file lib/silcutil/silcsockconn.c.
2778 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2780 * Added new function silc_socket_host_lookup to perform
2781 asynchronous IP and FQDN lookups for the socket connection.
2782 Affected files lib/silcutil/silcsockconn.[ch].
2784 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2786 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2787 that may or may not compile the mutex support in.
2789 Changed the silc_mutex_alloc interface. It allocates the
2790 mutex now to the sent pointer and returns TRUE or FALSE.
2792 Affected file lib/silcutil/silcmutex.h.
2794 * Wrote the SILC Task Queue interface to support multi-threads.
2795 Affected file lib/silcutil/silctask.[ch].
2797 * Wrote the SILC Scheduler to support multi-threads. Affected
2798 file lib/silcutil/silcschedule.c.
2800 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2802 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2803 in lib/silcutil/win32/.
2805 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2807 * Defined SILC Mutex API and SILC Thread API and implemented
2808 them for Unix. Affected files are
2809 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2810 lib/silcutil/unix/silcunixmutex.c and
2811 lib/silcutil/unix/silcunixthread.c.
2813 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2815 * Fixed the silc_server_remove_clients_by_server's channel
2816 key re-generation. The hash table handling was incorrect
2817 and would not work with many channels. Affected file is
2820 * Fixed some memory leaks around the server code.
2822 * Rewrote the silc_server_get_users_on_channel to support IPv6
2823 based Client ID's. Affected file silcd/server.c.
2825 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2826 specification. However, a separate document must be written
2827 to define the detailed signing procedure and the payload
2828 associated with the flag. Defined the flag to the
2829 lib/silccore/silcchannel.h as well.
2831 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2833 * Changed the dynamic tables to static size tables in the
2834 lib/silccrypt/silchmac.c.
2836 * Removed GCC dependencies from the code. A patch by cras.
2838 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2840 * Do not show the error "Error receiving packet bla bla"
2841 in server if it really was not an error (-2 means that reading
2842 is pending). Affected file silcd/server.c.
2844 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2846 * Fixed a possible crash in silc_server_remove_clients_by_server
2847 in silcd/server.c. Fixed there also some memory leaks.
2849 * Fixed the silc_idlist_replace_client_id. It could replace
2850 wrong key in the hash table. Affected file silcd/idlist.c.
2852 * Do not check whether there are global users on the channel
2853 if the channel->global_users is FALSE. Affected functions
2854 silc_server_remove_from_one_channel and
2855 silc_server_remove_from_channels in silcd/server.c. Also,
2856 do not check if the removed client is local as we can be
2857 sure that global client was not removed from the channel
2858 and checking for global users is not needed.
2860 * The silc_server_remove_clients_by_server now re-generates
2861 the channel keys correctly for those channels that had
2862 clients removed from them. Affected file silcd/server.c.
2864 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2866 * Found the reason of random crashes in the server. We weren't
2867 ignoring the SIGPIPE signal (which can be sent in write())
2868 and it crashed the server. Affected file silcd/silcd.c.
2870 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2872 * Assure that sock->user_data is not NULL in the function
2873 silc_server_packet_send in silcd/packet_send.c.
2875 * Disconnect the remote connection if it could not be added
2876 to any ID lists in the server. The affected file is
2879 * Check in silc_server_packet_send[_real/dest] that the
2880 socket is not disconnecting and ignore the data if it is.
2881 Affected file silcd/packet_send.c.
2883 * Define inline to __inline on native WIN32 compilation.
2884 Affected file includes/silcwin32.h.
2886 * Added some explicit type casts for inline code since MSVC
2887 require them. Affected files lib/silcutil/silcbuffer.h,
2888 lib/trq/silcdlist.h and lib/trq/silclist.h.
2890 * Print warning in log files from now on if the packet
2891 decryption fails. Affected file silcd/server.c.
2893 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2895 * Changed the `say' client operation's interface to accept
2896 new `type' argument to indicate the type of the message sent
2897 by the library. The application may filter the library's
2898 messages according the type. The affected file is the
2899 lib/silcclient/silcapi.h.
2901 * Added two new functions to lib/silcclient/silcapi.h:
2902 silc_client_del_client and silc_client_del_client_by_id.
2903 Affected file lib/silcclient/idlist.c.
2905 * Moved the clientincludes.h from includes/ to silc/ and
2906 serverincludes.h from includes/ to silcd/.
2908 * The modes for the CMODE and CUMODE are now passed as
2909 uint32 for application with COMMAND_REPLY. The affected
2910 file is lib/silcclient/command_reply.c.
2912 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2914 * /WHOIS without arguments shows client's own information.
2915 Affected file lib/silcclient/command.c.
2917 * Changed PING to not accept any arguments. The specs
2918 says that client can ping only the connected server so
2919 requiring an argument is not needed. Affected file is
2920 lib/silcclient/command.c.
2922 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2924 * Fixed a fatal bug in private message sending and reception
2925 encryption and decryption when using private message keys.
2926 The implementation was incorrect and did not follow the
2927 specification. It causd that some of the message were
2928 lost since it did not use the sending and receiving keys
2929 as the protocol suggests. This has been fixed and will cause
2930 incompatibilities with older clients when sending private
2931 message encrypted with private message keys. Affected files
2932 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2933 and various other in Irssi SILC Client.
2935 Added `responder' boolean argument to the functions
2936 silc_client_add_private_message_key[_ske] to indicate when
2937 the key is added as responder or initiator of the key
2940 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2942 * Removed the silc_ske_check_version function and created
2943 a SilcSKECheckVersion callback. Added also a function
2944 silc_ske_set_callbacks that is now used to set all SKE
2945 callbacks. The callback functions are not given to
2946 the SKE functions anymore, but this function is used to
2949 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2951 * Added `silc_version' argument to the silc_client_alloc
2952 to define the version of the application for the library.
2953 The library will use the version string to compare it
2954 against the remote host's (usually a server) version
2955 string. Affected file lib/silcclient/silcapi.h
2957 * Added the KE protocol context to Key Agreement context
2958 in client library so that we can abort the SKE if it
2959 is in process when we get timeout. Affected file is
2960 lib/silcclient/client_keyagr.c.
2962 * Do not resolve the client ID forever if it returns in the
2963 first time that such client does not exist. This was done
2964 for example with private message. Affected file is
2965 lib/silcclient/client_prvmsg.c.
2967 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2969 * Do not add regex.h for WIN32. The affected file
2970 includes/silcincludes.h.
2972 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2973 not work yet 100%. It generates the DLL's automatically
2974 when compiling with --with-win32 under cygwin.
2976 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2978 * lib/contrib/regex.c is not compiled on WIN32.
2980 * Added silc_net_get_socket_opt function to the
2981 lib/silcutil/silcnet.h.
2983 * Added includes/silcwin32.h for WIN32 specific includes
2986 * Do not use ptime structure or any of the posix process
2987 functions on WIN32 in lib/silccrypt/silrng.c.
2989 * Added silc_gettimeofday to provide generic function
2990 for struct timeval on all platforms. Added the function
2991 to lib/silcutil/silcutil.h.
2993 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2995 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2996 library as they clearly belong there. As a plus side we
2997 can make the actual socket connection routines platform
3000 Added also new generic function silc_socket_read and
3001 silc_socket_write (that used to be silc_packet_[read/write].
3002 The implementation of these are platform specific.
3004 * Added WIN32 specific routines of silc_socket_[read/write]
3005 to lib/silcutil/win32/silcwin32sockconn.c.
3007 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3009 * Added preliminary support for native WIN32 compilation under
3010 cygwin (using the -mno-cygwin option for GCC) to the
3011 ./configure.in.pre. The --with-win32 now prepares the
3012 compilation for native WIN32.
3014 * Rewrote the SILC Scheduler interface in the file
3015 lib/silcutil/silcschedule.h. The scheduler is now context
3016 based and does not have anymore any global static scheduler.
3017 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3018 and created lib/silcutil/win32 directory for WIN32 based
3021 * Added Unix specific network routines to the
3022 lib/silcutil/unix/silcunixnet.c and the old
3023 lib/silcutil/silcnet.c includes now only generic routines.
3025 Added WIN32 specific network routines to the
3026 lib/silcutil/win32/silcwin32net.c.
3028 * Added Unix specific utility functions from the
3029 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3031 * Added WIN32 SILC Scheduler to the file
3032 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3035 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3037 * Do not handle JOIN notify in the server if the target client
3038 is not registered (idata->registered == FALSE). The affected
3039 file is silcd/packet_receive.c.
3041 * Update the nickrec->founder in event_cumode in the Irssi SILC
3042 client. Affected file irssi/src/silc/core/silc-channels.c.
3044 * Fixed the CUMODE_CHANGE notify handling in the server when
3045 server and router are announcing their clients on channels.
3046 Now the mode changes are saved and notified correctly. The
3047 affected file is /silcd/packet_receive.c.
3049 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3050 They really did not replace the cache entry in the ID Cache.
3051 Now they do that. Affected file silcd/idlist.c.
3053 * Fixed the KICK notify handling in the Irssi SILC client to
3054 update the channel records so that the kicked client does not
3055 appear to be on the channel. The affected file is
3056 irssi/src/silc/core/silc-channels.c.
3058 * Always update the conn->current_channel when executing command
3059 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3061 * Fixed the KILL notify handling in Irssi SILC client to remove
3062 the killed client on all channels.
3064 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3066 * Fixed the silc_parse_command_line to remove extra spaces
3067 from the start and end of the arguments. Affected file is
3068 lib/silcutil/silcutil.c.
3070 * Cancel and free any active protocol in the function
3071 silc_server_close_connection. Affected file silcd/server.c.
3073 * Cancel and free any active protocol in the function
3074 silc_client_close_connction. Affected file is
3075 lib/silcclient/client.c.
3077 * Do not execute the KILL command for clients that are in
3078 history (ie. they are not in the network). Affected file is
3081 * Fixed KILL notify handling, client does not crash anymore.
3082 Affected file irssi/src/silc/core/silc-channels.c.
3084 * Reduced the default packet buffer size from 2048 to 1024 in
3085 lib/silccore/silcpacket.c.
3087 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3088 counter to the SKE context that is incresed when the SKE library
3089 performs async operation outside the library. If the outside
3090 process frees the SKE context and FREED status will be set
3091 and the library will detect after the sync operation that the
3092 libary is freed. The affected files are
3093 lib/silcske/silcske[_status].[ch].
3095 * Resolve the client entry information in the function
3096 silc_client_channel_message to assure that NULL pointer is not
3097 passed as client entry to the application. */
3099 * Fixed the task timeout calculation to assure that there is
3100 never negative timeouts. The affected file is
3101 lib/silcutil/silcschedule.c.
3103 * Fixed the channel user mode notification sending in server.
3104 It was sent point-to-point to the router (or to server by router)
3105 but it needs to be destined to a channel. The routines now
3106 supports sending the channel user mode notifys to the channels
3107 when announcing clients and channels. Affected files are
3108 silcd/server.c and silcd/packet_receive.c.
3110 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3111 It did not actually replace the old channel entry in the cache.
3112 Affected file lib/silcclient/client_notify.c.
3114 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3116 * Fixed a possible crash in silc_packet_send_prepare. It now
3117 assures always that there is enough space in the buffer and
3118 at the tail area of the buffer (for MAC).
3120 Fixed the inbound buffer reallocation in silc_packet_read.
3121 It was old code and did not handle the reallocation correctly.
3124 The affected file is lib/silccore/silcpacket.c.
3126 * Fixed buffer overflow in silc_parse_nickname in the file
3127 lib/silcutil/silcutil.c.
3129 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3131 * make install generates new server keys only if there is not
3134 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3136 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3137 Added check that if the NOREPLY is set then we will not send
3138 the away message. This avoids infinite loop of away messages
3139 if both clients are away. The affected file is
3140 lib/silcclient/client_prvmsg.c.
3142 * Fixed client crash if /NICK was given without arguments.
3143 Affected file lib/silcclient/command.c.
3145 * Server does not send the invite list in INVITE command back
3146 to the client if the list was not altered. Added this notion
3147 to the protocol spec as well. Affected file silcd/command.c.
3149 Fixed possible crash in INVITE command by checking the
3150 value of silc_server_get_client_route command.
3152 * Fixed the INVITE notify type handling. The arguments are now
3153 taken in correct order and client does not crash. The affected
3154 file is irssi/src/silc/core/silc-channels.c.
3156 Removed the "Inviting xxx to channel" message from the
3157 client library away and let the application handle it.
3158 Affected file lib/silcclient/command.c. Added that message
3159 to Irssi SILC client's message formats.
3161 * Fixed CMODE command crash in client. It now checks the
3162 amount of arguments correctly and does not crash. The affected
3163 file is lib/silcclient/command.c.
3165 * Do not create new channel automatically in silc_channels_join
3166 but check whether the channel by that name already exists.
3167 Affected file irssi/silc/core/silc-channels.c.
3169 * Do not send the SERVER_SIGNOFF to router if the disconnected
3170 entity was the router. Affected file silcd/server.c.
3172 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3173 SILC client as it was missing from there.
3175 Added the handling of the KICK notify to the Irssi SILC client
3176 as it was missing. Added "you have been kicked" message to
3177 Irssi SILC client's message modules formats.
3179 Added the handing of the KILL notify to the Irssi SILC client
3180 as it was missing. Added the kill message module formats
3183 The affected file is irssi/src/silc/core/silc-channels.c.
3185 * The router did not save the channel mode the server announced.
3186 Affected file silcd/packet_receive.c.
3188 * Fixed a possible crash in INFO command in server. If the
3189 server did not provide the server info it crashed. Affected
3190 file silcd/command.c.
3192 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3194 * Fixed the GETKEY command in the server to check also the
3195 global list. Otherwise the GETKEY would not work correctly
3196 in normal SILC server. Affected file silcd/command.c.
3198 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3200 * Fixed GETKEY crash, it crashed if the command did not succseed.
3202 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3204 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3205 is now real and not just an macro interface to GMP.
3207 Removed the entire GMP from the source tree and imported new
3208 NSS MPI library instead. Reason for removing GMP is that it is
3209 extremely large and compiles extremely slow. The NSS MPI
3210 is only a few files and compiles in less than 10 seconds.
3211 The speed is also about the same as GMP. The MPI is imported
3212 to lib/silcmath/mpi.
3214 If the system has GMP installed we will still use the GMP.
3215 If it is not then the NSS MPI will be compiled.
3217 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3219 * Merged a long nickname (127 characters long) crash bugfix from
3220 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3222 * Merged a freed memory reference bugfix from Irssi CVS tree.
3223 Affected file irssi/src/core/commands.c.
3225 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3227 * Added the server's public key sving and verification to the
3228 server when performing the SKE. This was missing and the
3229 remote server's (or router's) public key was accepted without
3230 checking whether we have it previously or trust it at all.
3231 Affected file silcd/protocol.c.
3233 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3235 * Check in the silc_server_timeout_remote if protocol is active
3236 and make sure that the protocol's final callback is called so
3237 that all memory if freed. Affected file silcd/server.c.
3239 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3241 * silc_server_whois_send_reply crashed the server if the nickname
3242 was 127 characters long. Affected file silcd/command.c.
3244 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3246 * Added sanity check to the silc_server_new_client. If the hostname
3247 is provided inside username then check that the provided hostname
3248 really is the same as the resolved one. If the hostname was not
3249 resolved then check it from the public key. Affected file is
3250 silcd/packet_receive.c.
3252 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3253 if the server disconnected us and the connection is not valid
3254 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3256 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3257 the library to the lib/silcutil/silcutil.[ch].
3259 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3261 * Close log file after open. Affected file
3262 lib/silcutil/silclog.c.
3264 * Check whether sock == NULL in silc_client_send_packet and return
3265 if it is. Affected file lib/silcclient/silcclient.c.
3267 * Check rec->entry == NULL in the Irssi SILC Client before
3268 sending the channel message. Affecte file is
3269 irssi/src/silc/core/silc-servers.c.
3271 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3273 * Merged a splitted window bugfix from Irssi CVS tree. The
3274 affected file is irssi/src/fe-text/textbuffer-view.c.
3276 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3277 It did not print nickname.
3279 * Improved the distributions system a bit.
3281 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3283 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3284 irssi/src/fe-text/gui-window.c.
3286 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3287 to in-active server. The affected file is
3288 irssi/src/silc/core/client_ops.c.
3290 * Resolve the client in USERS command reply if the entry does
3291 not have username resolved. The affected file is
3292 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3293 command to WHOIS command to really resolve stuff. The USERS
3294 is not used any more in any critical section so WHOIS can
3295 be used even though it might be slower than IDENTIFY.
3297 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3300 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Changed the protocol API a bit more consistent in the
3303 lib/silccore/silcprotocol.[ch].
3305 * Changed the following headers to ROBODoc format:
3307 lib/silccore/silcpayload.h
3308 lib/silccore/silcprotocol.h
3309 lib/silccore/silcsockconn.h
3311 All core library headers are now formatted.
3313 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3315 * Fixed a bug in Irssi SILC client; do not show that you are
3316 server/router operator if you really are not. Affected file is
3317 irssi/src/silc/core/client_ops.c.
3319 * Renamed silc_command_free_payload to silc_command_payload_free.
3320 Affected file lib/silccore/silccommand.h
3322 * Added silcmath.h to include the prototoypes of various routines
3323 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3326 * Changed the following headers to ROBODoc format:
3328 lib/silccore/silcchannel.h
3329 lib/silccore/silccommand.h
3330 lib/silccore/silcid.h
3331 lib/silccore/silcidcache.h
3332 lib/silccore/silcmode.h
3333 lib/silccore/silcnotify.h
3334 lib/silccore/silcpacket.h
3335 lib/silcmath/silcmath.h
3337 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3339 * Added checking to the server code not to start the server if
3340 ciphers and stuff are not configured properly. Affected files
3341 silcd/serverconfig.[h] and silcd/server.c.
3343 * Changed the layout of the header files of the public interfaces
3344 in the SILC libraries. The new layout supports ROBODoc
3345 documentation tool (and some others) so that it is easy to create
3346 a library reference manual. All the other headers and source
3347 code must still follow the CodingStyle document. Also source
3348 code must not include these ROBODoc stuffs, only the headers.
3349 Furthermore, all public interface headers must now be named
3350 by using `silc' prefix, example: silcapi.h, silccipher.h.
3351 Some files were renamed due to this. All the other headers
3352 must not be used as public interfaces. I will update the
3353 CodingStyle document later. Changed following headers, so far:
3355 lib/silcclient/silcapi.h
3356 lib/silccore/silcauth.h
3357 lib/silccore/silcprivate.h
3358 lib/silccrypt/silcdh.h
3360 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3364 * Removed silc_client_packet_send_flush from the client library
3365 as it is not needed. Affected file lib/silcclient/client.[ch].
3367 * Added printing of message of unresolved authentication method
3368 to the Irssi SILC client. Added it to the module formats.
3369 Removed the same message from the client library.
3371 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3373 * Added new distribution feature, DISTLABEL. Every distribution
3374 can define own preprocessor label that can be used in the
3375 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3376 file distributions, acconfig.h.pre and prepare.
3378 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Added Makefile.defines_int to include the actual definitions
3381 for Makefile.defines.in. Tested the new distribution system,
3382 created distributions and tested installation.
3384 * Added AWAY message printing to the Irssi SILC client. Added
3385 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3387 * Added SCONNECT command to call the SILC's CONNECT command.
3388 Cannot use CONNECT directly since Irssi uses that internally.
3389 Affected file irssi/src/silc/core/silc-servers.c.
3391 Added ACTION local command. It is same as ME command but takes
3392 the channel as mandatory argument.
3394 Rewrote some of the Irssi's help files to suite for SILC
3397 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3399 * Added Makefile.defines[.in] that should for now on be included
3400 in all Makefile.am file in the source tree. That file includes
3401 all common compilation definitions for SILC source tree.
3403 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3405 * Minor changes to the ./prepare script to change the package
3406 name according the distribution name to the configure.in.
3408 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3410 * Created new distribution system. Added file `distributions'
3411 that defines all the distributions that can be created out of
3412 the SILC source tree. The ./prepare script now reads that
3413 file to determine how to prepare the distributions. The
3414 first argument to the ./prepare is the name of the distribution
3415 and second is the version of the distribution. If given
3416 without arguments it creates the default (toolkit) distribution
3417 with the default version (defined in ./prepare).
3419 All Makefile.am files that are subject to the distributions
3420 are now named as Makefile.am.pre. These are ./Makefile.am
3421 and lib/Makefile.am. Others may be changed later.
3423 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3425 * Added invite list, ban list, some key management and connection
3426 error message printing to module formats in the Irssi SILC client.
3428 * Added new silc_client_set_away_message to set the away message
3429 that is back to the person who sent private message. The
3430 affected file lib/silcclient/silcapi.h and the
3431 lib/silcclient/client_prvmsg.c.
3433 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3435 * Fixed the private message sending in the Irssi SILC client,
3436 added local command KEY to the Irssi SILC client.
3438 Added key management and key agreement message formats to the
3439 irssi/src/fe-common/silc/module-formats.[ch].
3441 Added USERS (alias WHO) printing, server/router operator
3442 indication and LIST command printing to the module formats.
3444 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3446 * Fixed channel joining notify handling, cumode notify handling
3447 from Irssi SILC client.
3449 * Added SILC specific module-formats to the Irssi SILC client so
3450 that SILC specific message hilighting, colors etc is possible.
3451 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3453 Added channel mode, channel user mode, actions, notices,
3454 whois and whowas printing to the the module-formats.c.
3456 * Fixed a bug in channel deletion in the server. The channel
3457 is not left to the cache even if the channel founder auth mode
3458 is set when there are no users anymore on the channel. Affected
3459 file silcd/server.c.
3461 * The silc_net_localhost now resolves the entire hostname including
3462 the domain name. Affected file lib/silcutil/silcnet.c.
3464 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3466 * Changed the ask_passphrase client operation to be ascynchronous.
3467 It has now a completion callback and a context that the
3468 application must call after it has got the passphrase from
3469 the user. Affected files lib/silcclient/silcapi.h,
3470 lib/silcclient/protocol.c, lib/silcclient/command.c and
3473 Added SilcAskPassphrase callback that the application calls
3474 to deliver the passphrase to the library.
3476 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3477 The public key verification and especially a certificate
3478 verification is asynchronous procedure.
3480 Added new SILC_SKE_STATUS_PENDING status to indicate the
3481 request is pending and a callback will be called to finalize
3484 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3485 indicate that remote end did not send its public key (or
3486 certificate), even though we require it. Added check for this
3487 condition in the SKE. This was a security bug, now fixed.
3489 Defined new SilcSKEVerifyCbCompletion callback that is called
3490 when the verification process is completed.
3492 The affected files lib/silcske/silcske_status.h and
3493 lib/silcske/silcske.[ch].
3495 * Changed the verify_public_key client operation to be async
3496 as well. Defined SilcVerifyPublicKey callback that is used to
3497 indicate the success of the public key verification process.
3499 Changed the server and client to use the new async client
3502 * Changed the Irssi SILC client's internal scheduler to be called
3503 twice as many times as it used to be. As a result the client
3504 should be a bit faster now. Affected file is
3505 irssi/src/silc/core/silc-core.c.
3507 * Added support to Irssi SILC client of asynchronous public key
3508 verification and passphrase inquiry. Affected file is
3509 irssi/src/silc/core/silc-core.c.
3511 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3513 * Do not say "You have left channel %s" in client library.
3514 Moved it to the application. Affected files are
3515 lib/silcclient/command.c and silc/client_ops.c.
3517 * Fixed silc_client_get_clients. Command context was not
3518 duplicated and was freed memory in the callback. Affected
3519 file lib/silcclient/idlist.c.
3521 * Do not say "you are now talking..." on JOIN command in the
3522 client library. The appliation must handle it.
3524 * Do not say ".. changed topic to" in command reply in the
3525 client libary. The application must handle it.
3527 * Fixed TOPIC command sending in the client library.
3529 * Fixed a memory leak in silc_client_command_free in the file
3530 lib/silcclient/command.c.
3532 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3534 * Imported a modified version of Irssi client to the source tree.
3535 The Irssi will be used to create a new client called
3536 Irssi SILC. Imported to irssi/.
3538 Added silc_core_init_finish function to the Irssi. Affected
3539 file irssi/configure.in.
3541 A lot changes in the Makefile.ams around the irssi tree.
3543 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3545 * Do not rehash if the new size is same as the old size of the
3546 hash table, in the silc_hash_table_rehash*. The affected file
3547 lib/silcutil/silchashtable.c.
3549 * Replaced hash_table_del_by_context calls from the server
3550 (when channel->user_list and client->channels) to the
3551 hash_table_del as it is sufficient and faster.
3553 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3555 * Added silc_hash_table_list, silc_hash_table_get and the
3556 SilcHashTableList structure to provide an alternative way to
3557 traverse the hash table. The affected files are
3558 lib/silcutil/silchashtable.[ch].
3560 * Changed the server's idlist routines to use the hash table
3561 routines to optimize the code.
3563 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3565 * Replaced the client entry's `channel' list and channel entry's
3566 `user_list' list to hash tables for optimized lookup. Changed
3567 the code to use the hash table interface around the code.
3568 Affected file lib/silcd/idlist.[ch].
3570 * Added `auto_rehash' boolean argument to the function
3571 silc_hash_table_alloc to indicate whether the hash table should
3572 auto-rehash when it thinks is appropriate time. It will
3573 increase the hash table size if the there is twice as much
3574 entries in the table than the size of the table, and will
3575 decrease the size if there are twice as less entries than
3576 the size of the table.
3578 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3580 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3582 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3584 * silc_idcache_purge_by_context deletes the entry now by context
3585 as it is supposed to do. Affected file lib/silccore/idcache.c.
3587 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3588 client is not anymore valid (WHOWAS givens the info) and not
3589 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3591 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3593 * Removed the `data' and `data_len' arguments from the ID Cache
3594 interfaces and added `name' argument. ID Cache does not handle
3595 anymore the binary data only a names associated with given ID.
3597 * When hashing a Client ID with silc_hash_id the entire ID is
3598 not hashed anymore, instead only the hash of the Client ID is
3599 hashed. This way we can access the Client ID from the cache
3600 with Client ID but with the hash of the ID (which is a hash of
3601 the nickname) as well without any difference in performance.
3603 Added also silc_idcache_find_by_id_one_ext to do one on one
3604 searching when we have the actual ID. Added also function
3605 silc_hash_client_id_compare. The affected files are
3606 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3608 * When hashing the name associated with a ID it is always done
3609 in lowercase. This way we can access the cache without worrying
3610 about case-sensitivity, even though, for example nicknames are
3613 * Fixed a bug in server with channel message sending. It put
3614 wrong ID type as destination ID. The affected file
3615 silcd/packet_send.c.
3617 * silc_idcache_del_by_context now deletes from all hash tables
3618 by context. Affected file lib/silccore/idcache.c.
3620 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * Changed the client library to use the new ID Cache interface.
3623 Changes around the source tree.
3625 * Added silc_hash_table_rehash_ext to rehash with specific
3626 hash function. Affected file lib/silcutil/silchashtable.[ch].
3628 * Added silc_hash_string_compare to compare two strings in the
3629 hash table. Affected file lib/silcutil/silcutil.[ch].
3631 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Added new function silc_idcache_del_by_context into the
3634 lib/silccore/idcache.[ch].
3636 * Changed the server's ID list routines to use the new ID Cache
3637 interface. Changes around the source tree.
3639 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3641 * Added silc_hash_table_del[_by_context]_ext functions in to the
3642 lib/silcutil/silchashtable.[ch].
3644 Removed silc_hash_table_find_all* routines and added new
3645 silc_hash_table_find_foreach to replace them.
3647 Added silc_hash_table_replace_ext function as extended
3648 replacing function. Separated the simple hash table interface
3649 from the extended hash table interface in the file
3650 lib/silcutil/silchashtable.h.
3652 * Fixed minor bugs and changed it to use some of the new
3653 hash table functions in lib/silccore/idcache.c
3655 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3657 * Added new function silc_hash_table_find_all to return all keys
3658 in the hash table by the specified key. As the hash table is
3659 collision resistant it also makes it possible to have several
3660 duplicate keys in the hash table. This function may be used to
3661 find all of the keys from the hash.
3663 Added user_context arguments to the SilcHashFunction,
3664 SilcHashCompare and SilcHashDestructor to deliver user specified
3667 Added new fuctions silc_hash_table_find[_all]_ext to do
3668 extended lookup with specified hash and compare functions and
3669 specified user contexts.
3671 Added new function silc_hash_table_add_ext to add the key
3672 with specified hash function and user context.
3674 Added new function silc_hash_table_foreach to traverse all
3675 entrys in the hash table. Added SilcHashForeach callback
3678 Added new function silc_hash_table_del_by_context to delete
3679 the entry only if the context associated with the key matches.
3681 Affected files are lib/silcutil/silchashtable.[ch].
3683 * Removed silc_hash_[server/client/channel]_id and added just
3684 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3685 silc_hash_id_compare to compare two ID's using as the hash table
3686 comparison function. Added also silc_hash_data to hash
3687 binary data and silc_hash_data_compare to compare it.
3689 * Removed silc_idlist_find_client_by_hash as it is not needed
3690 anymore. Affected file silcd/idlist.[ch].
3692 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3693 to use internally the SilcHashTable. The new ID Cache is a lot
3694 faster than the old one. Some of the ID Cache interface was also
3695 rewritten and obsolete and stupid functions were removed.
3697 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3699 * Added entry_count field to the SilcHashTable to keep the number
3700 of the entries in the table. Implemented the function
3701 silc_hash_table_rehash. Added new function
3702 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3704 Fixed a minor bug in silc_hash_table_free.
3706 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3707 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3708 into the lib/silcutil/silcutil.[ch].
3710 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3712 * Implemented a collision resistant hash table into the
3713 lib/silcutil/silchashtable[ch]. See the header and the source
3714 for the SilcHashTable API.
3716 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3718 * Merged dotconf version 1.0.2 into lib/dotconf.
3720 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * Do not compile anything in lib/silcsim/* if the SIM support
3723 is not enabled. The tree should now compile without problems
3726 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3728 * Compiled the SILC under cygwin. Compiled and tested briefly
3729 without problems. More tests needed. The SIMs didn't compile
3732 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3734 * Fixed possible crash in silc_get_username in the
3735 lib/silcutil/silcutil.c.
3737 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3739 * Fixed a va_arg in silc/client_ops.c.
3741 * Oops, RC5 routines were named AES and caused some problems
3742 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3744 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3746 * Added new SilcIDIP structure into the lib/silccore/id.h and
3747 replaced the old `ip' fields from all SILC ID's to that type.
3748 This is a step towards IPv6 support.
3750 The silc_id_get_len takes now the ID as an extra argument.
3751 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3752 both IPv4 and IPv6 based ID's.
3754 The affected files are lib/silccore/id.[ch] and other files
3755 around the tree using these routines.
3757 * Removed the ID length arguments in server from various
3758 silc_server_send_notify_* routines -> they are not needed
3761 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Fixed memory leak in silc_encode_pem_file in the file
3764 lib/silcutil/silcutil.c.
3766 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3768 * Check minor version as well in the SKE. Affected files are
3769 silcd/protocol.c and lib/silcclient/protocol.c.
3771 * Added --identifier option to the server so that an identifier
3772 can be when creating the public key for the server. Affected
3773 file is silcd/silcd.c.
3775 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3776 lib/silccrypt/silcpkcs.c.
3778 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3780 * Register default ciphers and stuff when using -C option with
3781 the server. Affected file sildc/silcd.c.
3783 * Put back the servers public key filename format, it is better
3784 than the new one. For now, the client keys are saved with the
3785 new filename format. The affected file silc/client_ops.c.
3787 * Implemented the Cipher API for the rest of the ciphers that
3788 did not implement it or implemented it the wrong way.
3790 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Register default ciphers and stuff when using the -S option
3793 in the client. Affected file silc/silc.c. Same also when
3794 creating new key pair with -C option.
3796 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3798 * Fixed the silc_verify_public_key client operation function to
3799 save the public keys differently. The fingerprint is now
3800 used as filename and not the hostname. This way also the
3801 client keys are saved uniquely and not with hostnames. The
3802 affected file is silc/client_ops.c.
3804 * Trimmed the silc_hash_fingerprint function to remove extra
3805 whitespaces from the end of the fingerprint. The affected
3806 file is lib/silccrypt/silchash.c.
3810 * Added silc_cipher_register_default function to register all
3811 default ciphers. It can be used when configuration files
3812 does not exist and the application does not want any specific
3813 ciphers in any specific order.
3815 The SilcDList is now used as silc_cipher_list dynamically
3816 allocated cipher list. Removed the static list all together
3817 and now all ciphers must be allocated to the dynamic list.
3818 The silc_cipher_alloc routine was changed to check only the
3821 All silc_cipher_* routines that used to return int returns
3824 The affected files lib/silccrypt/silccrypt.[ch].
3826 * The same thing was done to silc_hash_* as for silc_cipher_*
3827 routines. Affected files lib/silccrypt/silchash.[ch].
3829 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3830 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3831 Added also silc_pkcs_[un]register[_default] functions.
3832 Removed the data_context from the PKCS API.
3834 * Added silc_hmac_register_default function to register default
3835 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3836 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3837 to unregister all hmacs at once.
3839 * Register the default ciphers, hash functions, PKCSs and HMACs
3840 if client's configuration file does not exist. The affected
3843 * The client did not load the hash functions from the SIM
3844 modules at all. Added support for this. Affected file is
3845 silc/clientconfig.c.
3847 * When decoding public key with silc_pkcs_public_key_decode, check
3848 the supported algorithm only if PKCS are registered. Affected
3849 file lib/silccrypt/silcpkcs.c. The same was done with the
3850 silc_pkcs_private_key_decode.
3852 * Fixed the SILC List routines to keep the list always in order.
3853 It used to change the list's order when traversing the list but
3854 not it preserves the order. Affected file lib/trq/silclist.h.
3856 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3858 * Added the client library to use the SilcSocketConnection's
3859 reference counter (by silc_socket_dup) to prevent the bug that
3860 the socket object may be freed underneath async operation.
3862 * The name resolv library checking fixes in the configure.in.pre.
3865 * Created new version of the protocol drafts for future
3866 development. The -03 drafts are the ones that will be changed
3867 in the trunk now and the -02 will remain as they are.
3869 * Send list of CUMODE notifys to the router when announcing
3870 the channel users to the router. Affected file silcd/server.c.
3871 If the router receiving channel founder CUMODE for a channel
3872 that already has channel founder it will send CUMODE notify
3873 to the sender to remove the channel founder rights from the
3874 announced client. Affected file silcd/packet_receive.c.
3876 * The CUMODE notify may now use Server ID as well as the entity
3877 who changes the mode. Updated protocool specs.
3879 * Updated INSTALL and README files.
3881 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3883 * New web pages in the http://silc.pspt.fi. The pages was
3888 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3890 * Implemented the [DenyConnectin] config section in the server.
3891 Added silc_server_config_denied_conn to check whether incoming
3892 connection is denied. Affected file silcd/serverconfig.[ch].
3894 * Do not check the ports when checking the incoming configuration
3895 data if the port is 0, meaning any. Affected file is
3896 silcd/serverconfig.c.
3898 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3900 * Fixed buffer overflow in silc_string_compare in the file
3901 lib/silcutil/silcutil.c.
3903 * Fixed double free in silc_server_command_leave in the file
3906 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3908 * Fixed the version checking in the server. Affected file is
3911 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3913 * Fixed the configuration data fetching when accepting new
3914 connections in the server. Affected file silcd/server.c.
3916 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3918 * Added `sender_entry' argument to the function
3919 silc_server_packet_relay_to_channel so that we can check
3920 whether some destination actually belongs to the same route
3921 the sender belongs (ie, we must not resend the packet to the
3922 sender). Affected file silcd/packet_send.[ch].
3924 * Added `servername' field to the SilcClientEntry in the server
3925 to hold the name of the server where client is from. Affected
3926 file is silcd/idlist.h.
3928 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3930 * Moved the channel message encrypting in the router betwen
3931 router connections from silc_server_channel_message to the
3932 silc_server_packet_relay_to_channel since we want to check
3933 whether we have anybody channel before encrypting anything.
3934 Affected files silcd/packet_[receive/send].c.
3936 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3938 * Fixed the [AdminConnection] server config section to support
3939 multiple entries. Affected file silcd/serverconfig.c.
3941 * Added support into the server to check the validity of the
3942 incoming connection before executing any KE or authentication
3945 * The connection configuration is now saved to the KE and
3946 connection auth protocol contexts and not fetched anymore in
3947 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3949 * The local hosts listenning address and port is also resolved
3950 now when starting the server. We want to have the socket object
3951 to include the real address and port for the listener. Added
3952 new function silc_net_check_local_by_sock into the files
3953 lib/silcutil/silcnet.[ch].
3955 * Fixed a broadcast bug in server -> do not broadcast if we
3958 * Fixed a routing bug. Do not route broadcast packets ever.
3959 Broadcast packets must be processed always and not routed since
3960 they may be destined to some other host than yourself and thus
3961 would get routed without no good reason. Affected file is
3964 * Added function silc_server_config_is_primary_route to check
3965 whether primary router connection has been configured (a router
3966 configuration that we are initiating). If there is not, we
3967 will assume that there is only two routers in the SILC network
3968 and we will use the incoming router connection as our primary
3969 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3971 * Changed the order of the broadcasting. Broadcast _after_ the
3972 packet has been processed not before. Affected file is
3975 * Fixed a [ClientConnection] parsing bug. The port was never
3976 parsed correctly thus resulting to port 0. Affected file
3977 silcd/serverconfig.c.
3979 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3980 argument and did not set the broadcast packet flag. Affected
3981 file silcd/packet_send.c. Fixed same bug in the function
3982 silc_server_send_notify as well.
3984 * If we receive NEW_ID packet for our own ID in the server, ignore
3987 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3991 * Removed the nickname from the Private Message Payload.
3992 Updated the code and the protocol specs.
3994 * Updated protocol specs for submitting to the IETF.
3996 * Tweaked the Random Number Generator a bit. Affected file
3997 lib/silccrypt/silcrng.c. Exported a new function
3998 silc_rng_[global]_add_noise which can be used to add more
4001 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4003 * Do not parse packets with different timeout when protocol
4004 is active -> may cause problem with rekey. Affected file
4007 * When server receives signoff notify it must not create
4008 new channel key if the client is on any channels since the
4009 sender of the signoff notify will create it.
4011 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4013 * Added printing of error messages during SKE protocol from the
4014 failure packet sent by server during SKE. Affected file
4017 * Removed the client's failure_callback handling with timeout
4018 and handle it immediately when received.
4020 * The SKE library returned wrong type in SUCCESS and FAILURE
4021 packets. They must be 32 bit MSB not 16 bit MSB.
4023 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4025 * Ok, rewrote the logic of the re-key and now it seems to work.
4026 I tested it on high traffic with frequent re-keys without
4027 problems. Added hmac_receive (and renamed hmac to hmac_send)
4028 in SilcClientConnection in lib/silcclient/client.h and
4029 in SilcIDListData in silcd/idlist.h. Also, removed the
4030 SilcPacketParserContext's cipher and hmac fields as they are
4031 not needed anymore and actually caused some problems when
4032 the ciphers and hmac's changed underneath the packet parser.
4034 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4036 * If re-key protocol is active then process the incoming packets
4037 synchronously since we must assure that icoming packets encrypted
4038 with the old key is processed before the new keys is set to
4039 use. This is true other packets than for REKEY packets.
4040 Affected file silcd/server.c. The same was done to client library
4041 as well, affected file lib/silcclient/client.c.
4043 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4045 * Fixed bug in client and server to accept the force send if
4046 the packet is send from silc_[server/client]_packet_process
4047 function. Otherwise the packets are never delivered, oops.
4049 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4051 * Disable force sending of packets when REKEY protocol is active.
4052 We must assure that no packet is sent directly when rekey is
4053 performed. All packets must be sent through packet queue.
4054 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4055 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4056 function is silc_[server/client]_packet_send_real to check
4059 * Replaced the SIM paths from example config files to
4060 /usr/local/modules. Also, make install creates now
4061 /usr/local/silc/logs directory to hold all the SILC server
4064 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4066 * Made the configure.in.pre work on Solaris. Patch by salo.
4068 * Made all ciphers compatible with non-x86 machines. Defined
4069 CBC mode macros into lib/silccrypt/ciphers_def.h.
4071 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4073 * Fixed the make install.
4075 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4077 * When MAC computation fails the silc_packet_decrypt returned 0
4078 even though it was supposed to return -1. Fixed this. The
4079 affected file is lib/silccore/silcpacket.c.
4081 * Do not replace the config files in /etc/silc (in make install)
4082 if they already exist. Affected file ./Makefile.am.
4084 * Do not send re-key packets immediately but through packet queue.
4085 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4087 * Changed silc_net_check_host_by_sock to return FALSE if the
4088 IP/DNS could not be resolved. Though, it returns the IP address
4089 now even if it could not resolve it (but returns also FALSE).
4090 Affected file lib/silcutil/silcnet.[ch].
4092 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4094 * Added silc_pkcs_decode_identifier to decode the public key's
4095 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4096 Added also silc_pkcs_free_identifier. Added also new context
4097 SilcPublicKeyIdentifier.
4099 * Added -S option to the silc client. It is used to dump the
4100 contents of the specified public key file.
4102 * Changed the PKCS api to return the public key length when
4103 setting the public key.
4105 * Fixed a fatal bug in the public and private key file loading.
4106 Affected file lib/silccrypt/silcpkcs.c.
4108 * Execute the packet parsing for client with zero (0) timeout
4109 if the protocol is active. Affected file silcd/server.c.
4111 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4113 * Made the key generation options to the silcd program. Added
4114 -C option, equivalent to client's option.
4116 * Added new [ServerKeys] config section to the server. It
4117 configures the server's public and private key.
4119 * Defined generic Public Key Payload into the protocol
4120 specification to send specific type of public keys and
4123 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4124 public key or certificate.
4126 * Implemented the GETKEY command to the server and to the
4127 client library and on user interface.
4129 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4131 * Made preliminary `make install' work.

4160 SilcClientConnection structure; not needed. Affected file is
4161 lib/silcclient/client.h.
4165 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4167 * Do not ask whether user wants to use the negotiated private key
4168 for private messages, just use it. Affected file is
4169 silc/local_command.c.
4171 * Added `send_enc_key' and `enc_key_len' fields to the
4172 SilcIDListData structure since they are needed in the re-key
4173 phase. Affected file is silcd/idlist.[ch].

4187 the PFS is to be performed in the re-key. Affected file is
4190 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4192 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4193 int64 of at least the xintXX size. If void * is less that 4
4194 bytes uint32 * will be used. Defined bool as boolean.
4196 * Changed _ALL_ unsigned long and unsigned int to uint32,
4197 unsgined short to uint16 in the source tree.
4199 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4200 not handle clients that has entry->data.registered == FALSE.
4201 They are not in the network anymore. Affected file is
4204 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4206 * Implemented the sending of the SERVER_SIGNOFF notify in the
4207 server. Affected file is silcd/server.c.
4209 * Added silc_server_send_notify_args into silcd/packet_send.[ch].

4214 Affected file silcd/packet_receive.c.
4216 * Implemented the SERVER_SIGNOFF notify handling in the client
4217 library. Affected file lib/silcclient/client_notify.c. Also,
4218 implemnted the printing of the SERVER_SIGNOFF info to the
4219 application. Affected file silc/client_ops.c.
4221 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4222 if the deleting was successful. Affected file silcd/idlist.[ch].
4224 * Added support for public key authentication in the connection
4225 authentication protocol in the client library. Affected file
4226 lib/silcclient/protocol.c.
4228 * Changed the server's silc_idlist_get_clients_by_* interface
4229 to support already allocated array so that new entries may be
4230 added to pre-allocated array. Affected file silcd/idlist.[ch].
4231 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4232 and command replies.
4234 * All command reply functions in the server now calls the
4235 pending command callback even if error occured. This way the
4236 error will be delivered to the client as well. Affected files
4237 silcd/command.c and silcd/command_reply.c.
4239 * Fixed INFO command to return local server's info if no server
4240 was provided. Affected file lib/silcclient/command.c.
4242 * Removed RESTART command for good. Updated the code and the

4249 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Moved the USERS printing from the library to the application.
4252 Affected files lib/silcclient/command.c and silc/client_ops.c.
4254 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4258 * Added channel key re-key support. The re-key is perfomed
4259 only by the router and is done once in an hour. Added `rekey'
4260 field to the SilcChannelEntry in the server. Affected files
4261 silcd/server.c and silcd/idlist.h.
4263 * Added silc_task_unregister_by_context into the file
4264 lib/silcutil/silctask.[ch].
4266 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4268 * Added SILC_UMODE_GONE mode to indicate when the client is not
4269 present in the SILC network. Added also support to the local
4270 command AWAY that will set this mode. Added support of showing
4271 "xxx is gone" in WHOIS command. The USERS command shows the
4272 gone status as well.
4274 * Fixed setting server and router operator privileges in the
4275 server's UMODE command. Affected file silcd/command.c.
4277 * Merged the SKE KE1 and KE2 payloads into one payload. The
4278 new KE payload is equivalent to the old KE2 payload.
4280 Cleaned up the SKE Start Payload parsing. It now uses the
4281 simple buffer unformatting to do the parsing. A lot faster
4284 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4285 to the SKE that is used to indicate whether both of the SKE
4286 parties should perform authentication. By default only the
4287 responder performs authentication. By setting this flag also
4288 the initiator must do authentication. By default it is unset
4289 since in normal SKE case, client to server connection, only
4290 the responder should do authentication. When doing SKE between
4291 two clients both should perform authentication. Updated the
4292 code and the protocol specs.
4294 * A little fix to IDENTIFY command in the server. Search the
4295 client first by hash not nickname. Affected file is
4298 * Fixed the silc_client_close_connection to support closing
4299 the client to client connections wihtout deleting too much
4300 data. Affected file lib/silcclient/client.c.
4302 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4303 are received if protocol used to be active but is not anymore
4304 the application would crash due to NULL pointer dereference.
4305 Affected files silcd/server.c and lib/silcclient/client.c.
4307 * Added `hash' field to the SilcClientConnection to include
4308 the hash function negotiated in the SKE protocol.
4310 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4311 to set the channel founder authentication data. A client can
4312 claim the founder rights later by providing the authentication
4313 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4314 This way the channel founder can regain the channel founder
4315 privileges even it is left the channel. This works only on
4316 local server and the client must be connected to the same
4317 server to be able to regain the founder rights. Updated the
4318 protocol specs accordingly.
4320 Added support to the CMODE command in the client to set the
4321 founder auth data. Read the README to see how to set it.
4323 Added support to the CUMODE command to claim the founder
4324 rights. Read the README to see how to do it.
4326 Added support for the founder authentication to the Channel
4327 Entry in the server. Affected file silcd/idlist.h.
4329 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4330 server's CMODE command. Affected file silcd/command.c.
4332 * Added the following new functions into lib/silccore/silcauth.[ch]:
4333 silc_auth_get_method and silc_auth_get_data.
4335 * The server now saves the remote hosts public key to the
4336 SilcIDListData pointer. Affected file silcd/protocol.c.
4338 * The normal server now does not remove the channel entry from
4339 the cache if the founder authentication data is set. It used
4340 to remove it if the founder was the last one on the channel on
4341 the server and left the channel. The auth data is saved and
4342 if the channel is re-joined later the old entry is used with
4343 the old auth data. Affected files silcd/command_reply.c and
4346 * Removed the `pkcs' field from the SilcIDListData structure
4347 in the server; it is not used. Affected file silcd/idlist.h.
4349 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Fixed packet processing on slow links. Partial packets were
4352 never re-processed because the incoming data buffer was cleared
4353 by the application. Application must not directly clear the
4354 sock->inbuf, the packet processing routines handle it. Fixed
4355 this in client library and in server.
4357 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4359 * Fixed the WHOIS and IDENTIFY send reply function to really
4360 check whether to send list or just one entry. Affected file
4363 * Cleaned up the LEAVE command's channel key distribution. The
4364 affected file silcd/command.c.
4366 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4367 can enforce the channel mode as well. In that case the ID
4368 includes the ID of the server. The code now enforces the
4369 mode change if the router have different mode than the server.
4371 * The notify client operation with CMODE_CHANGE notify can now
4372 return NULL client_entry pointer if the CMODE was not changed
4373 by client. Application must check for this.
4375 * Added <Server ID> argument to INFO command to support server
4376 info fetching by Server ID.
4378 * Added silc_server_announce_get_channel_users to get assembled
4379 packets of channel users of the specified channel. Affected
4380 file silcd/server.[ch].
4382 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4383 was freed underneath the ID Cache.
4385 * Re-announce clients when the server received CHANNEL_CHANGE
4386 notify from the router. Affected file silcd/packet_send.c.
4388 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4390 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4391 crashed since it did not handle the fact that there is no cipher
4392 called "3" and didn't check the error condition. Now fixed.
4394 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4395 flag. It can be used to send message requests.
4397 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4399 * Implemented the RESTART command in the client.
4401 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4402 notice type messages. Added notice printing to the user
4405 * The channel keys are not re-generated if the channel's mode
4406 is PRIVKEY, ie private key on the channel exists. Affected
4407 files silcd/server.c and silcd/command.c.
4409 * Fixed a little bug in channel message delivery when channel
4410 private keys are set in the server. Affected file is
4411 silcd/packet_send.c.
4413 * Changed the setting on channel->on_channel = TRUE from the
4414 silc_client_save_channel_key to the JOIN command reply. The
4415 key payload is not received if the private channel key is set.
4416 Affected file lib/silcclient/command_reply.c and the
4417 lib/silcclient/client_channel.c.
4419 * When the CMODE_CHANGE notify is sent and the channel private
4420 key mode is removed the channel key must be re-generated in
4421 other cells as well. Added this support for the router in the
4422 silcd/packet_receive.c.
4424 * Added new local command NOTICE to send notice message on
4425 channel. Affected file silc/local_command.[ch].
4427 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4429 * Added new local command ME to the client. It is used to send
4430 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4431 some action. Affected file silc/local_command.[ch].
4433 * Changed channel_message and private_message client operations
4434 to deliver the message flags to the application. Added also
4435 the `flags' arguments to the silc_client_send_channel_message
4436 and silc_client_send_private_message functions. Affected file
4439 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * Redefined the Private Message Payload to support private message
4442 keys and to support the new private message flags. Updated
4443 the protocol specs. Flags makes it possible to have for example
4444 CTCP style messages.
4446 * Added new type SilcPrivateMessagePayload and defined an API
4447 for it in the lib/silcclient/silcprivate.[ch].
4449 * Tested private message private keys successfully. Tested the
4450 private message key set, unset and list commands with the new
4453 * Redefined the Channel Message Payload to include the channel
4454 message flags (equal with private message flags) to support
4455 for example CTCP style messages.
4457 * Defined some of the message (for channel and private message)
4458 flags. Updated the protocol specs and added the flags to the
4459 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4461 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Added SilcKeyAgreementStatus type to the key agreement routines
4464 to indicate the current status and error if one occured.
4465 The status types are defined in the lib/silcclient/silcapi.h.
4467 * Added new local command KEY that is used to set and unset private
4468 keys for channels, set and unset private keys for private messages
4469 with remote clients and to send key agreement requests and
4470 negotiate the key agreement protocol with remote client. The
4471 key agreement is supported only to negotiate private message keys,
4472 it currently cannot be used to negotiate private keys for channels,
4473 as it is not convenient for that purpose.
4475 * Fixed a minor pending callback setting bug in the function
4476 silc_client_get_client_by_id_resolve, now the function works.
4477 Affected file lib/silcclient/idlist.c.
4479 * Added function silc_net_get_local_port to get local bound
4480 port by socket. Added to lib/silcutil/silcnet.[ch].
4482 * Added `sockets' and `sockets_count' fields to the SilcClient
4483 object. They hold the sockets of the listenning sockets in
4484 the client. Listenning sockets may be for example the key
4485 agreement server. Affected file lib/silcclient/client.[ch].
4486 Added functions the silc_client_add_socket and the
4487 silc_client_del_socket. They are exported to the application
4490 * Added ~./silc/clientkeys to support other client's public keys.
4492 * Renamed verify_server_key client operation to verify_public_key
4493 and added one argument to indicate the type of the connection
4494 (server, client etc.).
4496 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * Added silc_server_connection_auth_request to handle the
4499 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4500 silcd/packet_receive.[ch].
4502 * Added silc_server_send_connection_auth_request into the
4503 silcd/packet_send.c to send the connection auth request packet.
4505 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4508 * Fixed the public key authentication in responder side in the
4509 server. The `auth_data' pointer includes the SilcPublicKey
4510 not the path to the public key. Affected file silcd/protocol.c.
4512 * Implemented the public key authentication in the initiator side
4513 in the server. Affected file silcd/protocol.c.
4515 * Removed the [RedirectClient] config section from the server
4516 configuration. Is not needed and I don't want to implement it.
4518 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4520 * Cleaned up the CMODE command in the server. It now works
4521 correctly and supports all the modes defined in the protocol.
4522 Affected file is silcd/command.c.
4524 * Added `hmac_name' field to the SilcChannelEntry in the server
4525 to hold the default HMAC of the channel. It can be set when
4526 creating the channel (with JOIN command). Affected files
4529 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4530 type to indicate the change of the current cipher and hmac
4531 on the channel. Client can safely ignore the <cipher> argument
4532 (if it chooses to do so) since the CHANNEL_KEY packet will
4533 force the channel key change anyway. The <hmac> argument is
4534 important since the client is responsible of setting the new
4535 HMAC and the hmac key into use.
4537 * Fixed the CMODE command in the client library as well.
4539 * Tested CMODE command in router environment successfully.
4541 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4543 * Show the version of the remote client (or server) when connecting
4544 to the server. It is logged to the log file. Affected file
4545 is silcd/protocol.c.
4547 * Fixed the KILLED notify handling in the client library. The
4548 client must be removed from all channels when receiving the
4551 Also, do not remove the client entry when giving the KILL
4552 command but when the KILLED notify is received.
4554 * Removed silc_idlist_find_client_by_nickname from the server.
4555 Not needed anymore. Affected files silcd/idlist.[ch].
4557 * Implemented the CHANNEL_CHANGE notify type handling to the
4558 server. Affected file silcd/server.c.
4562 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4564 * Added silc_server_send_notify_invite to send the INVITE
4565 notify between routers.
4567 * Implemented the INVITE command correctly to the server.
4569 * Implemented the INVITE notify type handling in the server.
4571 * Implemented the INVITE command to the client library and on the
4574 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4576 * Added function silc_server_get_client_resolve to find the
4577 client entry by ID from all ID lists and then resolve it
4578 (using WHOIS) if it cannot be found. Affected file is
4581 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4583 * Implemented the BAN command to the client library.
4585 * The JOIN command in the server now checks the invite list
4588 * Changed the silc_command_reply_payload_encode_va and the
4589 silc_command_payload_encode_va to support that if argument is
4590 NULL it ignores and checks the next argument. Affected file
4591 lib/silccore/silccommand.c.
4593 * Added silc_server_send_notify_ban to send the BAN notify
4594 type between routers.
4596 * Chaned the silc_notify_payload_encode to support that if
4597 argument is NULL it ignores and checks the next argument.
4598 Affected file lib/silccore/silcnotify.c.
4600 * Tested ban lists in router environment successfully.
4602 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4604 * Implemented BAN command to the server, in silcd/command.[ch].
4606 * Removed the BAN and INVITE_LIST modes from the CMODE command
4609 * Added function silc_string_match to regex match two strings.
4610 Affected files lib/silcutil/silcutil.[ch].
4612 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4614 * Redefined parts of the SilcChannelEntry in the server to support
4615 the new ban and invite lists.
4617 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4619 * Redefined the INVITE command. The same command can be used to
4620 invite individuals to the channel but also to manage the invite
4621 list of the channel (to add to and remove from the invite list).
4622 Updated the protocol specs.
4624 * Added new command SILC_COMMAND_BAN that can be used to manage
4625 the ban list of the channel. Updated the protocol specs.
4627 * Removed the channel modes: the SILC_CMODE_BAN and the
4628 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4629 in the CMODE command. The equivalent features are now available
4630 using INVITE and BAN commands. Updated the protocol specs.
4632 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4633 in the network about change in the current ban list. The notify
4634 type is not used by the client.
4636 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4637 support the invite lists.
4639 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Added new function silc_string_regexify that converts string
4642 including wildcard characters into regex string that can
4643 be used by the GNU regex library. Added into the file
4644 lib/silcutil/silcutil.[ch].
4646 Added silc_string_regex_combine to combine to regex strings
4647 into one so that they can be used as one regex string by
4648 the GNU regex library. Added into the file
4649 lib/silcutil/silcutil.[ch].
4651 Added silc_string_regex_match to match two strings. It returns
4652 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4654 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4656 * Imported GNU regex to the soruce tree into lib/contrib.
4657 Fixed some compiler warning from the regex.c.
4659 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * Fixed MOTD command in the server to work in router environment.
4663 * Fixed the MOTD command in the client library to support
4664 the server argument in the command.
4666 * Added `nickname_len' argument to the silc_idlist_add_client
4667 in the server, as the `nickname' argument may be binary data
4670 * Added silc_idlist_get_channels to return all channels from
4673 * Implemented LIST command to the server. Affected file is
4676 * Implemented the LIST command to the client library and on the
4679 * Added [<user count>] argument to the LIST command reply.
4680 With private channels the user count is not shown.
4682 * Updated TODO and README.
4684 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4686 * The client entry's data.registered must be TRUE even with
4687 global client entry on global client list. The data.registered
4688 is used to check whether the client is anymore in the network,
4689 for example with WHOWAS command so it must be valid.
4691 * Fixed the WHOWAS command in the server. It now actually works
4692 in router environment. Added function into silcd/command_reply.c
4693 silc_server_command_reply_whowas_save.
4695 * Added silc_idlist_purge function to the silcd/idlist.c
4696 to periodically purge the ID Cache.
4698 * Fixed INFO command in the server. It works now in router
4699 environment. Added <server name> argument to the INFO command
4700 reply. Updated the protocol specs.
4702 * Fixed minor bug in silc_idcache_purge to not purge if the
4703 expire value is zero.
4705 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4706 they were buggy because of the WHOWAS information.
4708 * Fixed local command MSG to handle the async resolving of
4709 the remote client properly. It used to fail the first MSG.
4710 Affected file silc/local_command.c.
4712 * Added `data_len' field to SilcIDCache context.
4714 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4716 * Update TODO. Todo in commands in the server.
4718 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4720 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4721 used by routers as broadcast packet to inform other routers
4722 about the changed user mode.
4724 Implemented the notify handling in the server. Affected file is
4725 silcd/packet_receive.c. Added the function
4726 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4728 * Added new generic Channel Payload and deprecated the New Channel
4729 Payload. The New Channel Payload is now the generic Channel
4732 * Added new argument `mode' to the silc_server_send_new_channel
4733 as it is required in the Channel Payload now.
4735 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4736 and created a new and real SilChannelPayload to represent the
4737 new generic Channel Payload. Implemented the encode/decode
4738 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4740 * Added silc_server_get_client_channel_list to return the list
4741 of channels the client has joined for WHOIS command reply.
4742 Affected file silcd/server.[ch].
4744 * Implemented the channel list sending in the WHOIS command reply
4745 in server and in the client.
4747 Implemented the channel list displaying on the user interface
4748 as well. Affected file silc/client_ops.c.
4750 * Added silc_channel_payload_parse_list to parse list of Channel
4751 Payloads. It returns SilcDList list of SilcChannelPayloads.
4752 Client for example can use this function to parse the list of
4753 channels it receives in the WHOIS command reply. The caller
4754 must free the list by calling silc_channel_payload_list_free.
4755 Affected files lib/silccore/silcchannel.[ch].
4757 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4759 * Added one new argument <user mode> to the WHOIS command reply
4760 to return the mode of the user in SILC. Updated the protocol
4763 Implemented it to the server and client.
4765 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4767 * Fixed the mode printing on the user interface on joining.
4768 Affected file silc/client_ops.c.
4770 * Implemented the UMODE command and user modes in general to the
4771 client library and to the user interface.
4773 * Implemented the UMODE command to the server.
4775 * The server now sends UNKNOWN_COMMAND error status if client sends
4776 unknown command. Affected file silcd/command.c.
4778 * All server commands now handle the command identifier the right
4779 way when sending the command reply to the client. The client can
4780 use to identify the command replies with the identifier.
4782 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4784 * Added silc_server_get_client_route to resolve the route to
4785 the client indicated by the client ID. Affected file is
4788 * Added silc_server_relay_packet as general function to relay
4789 packet to arbitrary destination. This deprecates functions
4790 like _send_private_message_key, _relay_notify etc. Affected
4791 file is silcd/packet_send.[ch].
4793 Removed silc_server_send_key_agreement,
4794 silc_server_send_private_message_key and
4795 silc_server_packet_relay_notify functions from the file
4796 silcd/packet_send.[ch].
4800 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4801 server. Affected file silcd/packet_receive.[ch].
4803 * Implemented the KILL command to the client. Implemented the
4804 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4805 Affected files lib/silcclient/command[_reply].c and
4806 lib/silcclient/client_notify.c. Implemented the KILL notify
4807 printing in the user inteface.
4809 * Fixed a lot silc_parse_nick memory leaks from the client
4810 library in the file lib/silcclient/command.c.
4812 * Changed the silc_server_send_notify_on_channels's `sender'
4813 argument from SilcSocketConnection to SilcClientEntry to
4814 check the sender as entry and not as connection object and not
4815 to send to the client provided as argument. The affected file
4816 is silcd/packet_send.[ch].
4818 * The notify packets that are destined directly to the client used
4819 to not to be processed by the server. Now changed that and the
4820 server processes all notify packets. After relaying the packet
4821 to the client the notify packet is processed in the server.
4823 * The silc_server_free_client_data now checks whether there is
4824 pending outgoing traffic for the client and purges the data to
4825 the network before removing the client entry.
4827 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4829 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4830 an client is killed from the SILC Network. Updated the protocol
4833 Added new function silc_server_send_notify_killed to the
4834 silcd/packet_send.[ch].
4836 * Added function silc_server_packet_relay_notify to relay notify
4837 packets that are destined directly to a client. In this case
4838 the server does not process the notify packets but merely relays
4839 it to the client. Affected file silcd/packet_send.[ch].
4841 Added also silc_server_packet_process_relay_notify to check
4842 whereto relay the notify. Affected file is
4843 silcd/packet_receive.[ch].
4845 * Implemented the KILL command to the server.
4849 * Added the backup schema desgined last fall to the protocol
4850 specs for everyone to see. The specification is in the
4851 *-spec-xx.txt draft and the packet type definitions for the
4852 backup routers is in *-pp-xx.txt draft. Thusly, added also
4853 new packet type SILC_PACKET_CELL_ROUTERS.
4855 * A big security problem in the implementation discovered. The
4856 signoff of an client did not cause new channel key generation
4857 which it of course should've done. The channel keys must be
4858 always re-generated when client leaves (or signoffs) the channel.
4859 The silc_server_remove_from_channels funtion now handles
4860 the channel key re-generation.
4862 * Added `sender' argument to the silc_server_send_notify_on_channels
4863 to not to send the client provided as argument. Affected file
4864 silcd/packet_send.[ch].
4866 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4868 * Implemented OPER and SILCOPER commands into the server and
4871 * Added silc_auth_verify and silc_auth_verify_data to verify
4872 the authentication directly from the authentication payload.
4873 It supports verifying both passphrase and public key based
4874 authentication. Affected file lib/silccore/silcauth.[ch].
4876 * Added `hash' field to the SilcIDListData structure. It is the
4877 hash negotiated in the SKE protocol. Affected file is
4880 * Slight redesigning of the SilcAuthPayload handling routines.
4881 Do not send SilcPKCS but SilcPublicKey as argument.
4883 * Implemented the public key authentication support to the
4884 serverconfig. The public key is loaded from the provided path
4885 and saved as authentication data to void * pointer. Thus,
4886 changed the unsigned char *auth_data to void *auth_data;
4888 * Fixed SHUTDOWN command to send the reply before the server
4889 is shutdown. :) Affected file silcd/command.c.
4891 * Fixed fatal bug in CONNECT command. The hostname was invalid
4892 memory and server crashed. Affected file silcd/command.c.
4894 * Fixed fatal bug in CLOSE command. The server_entry became
4895 invalid but was referenced later in the command. Affected file
4898 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4900 * Fixed fatal bug in failure packet handling. Server ignored
4901 the failure and thus crashed when it came.
4905 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4908 that the command may be executed only once in (about) 2 seconds.
4909 The old SILC_CF_LAG flag is same but allows command bursts up
4910 to five before limiting.
4912 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4913 server code. Various commands now includes the CF_LAG_STRICT
4914 flag to disallow any kind of miss-use of the command.
4916 * Fixed the silc_buffer_unformat to not to allocate any data
4917 if the length of the data is zero. It used to allocate the
4918 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4920 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4922 * Changed the format of AdminConnection configuration section
4923 in the server. Added username of the admin to the format.
4924 Affected files silcd/serverconfig.[ch].
4926 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4927 to return admin configuration data by host, username and/or
4930 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4932 * Implemented WHOWAS command to the server. Added the functions:
4934 silc_server_command_whowas_parse,
4935 silc_server_command_whowas_send_reply,
4936 silc_server_command_whowas_from_client and
4937 silc_server_command_whowas_from_server
4939 * Added <Client ID> argument to the WHOWAS command reply. Updated
4940 the protocol specs accordingly.
4942 * Implemented WHOWAS command and command_reply to the client
4945 Implemented the WHOWAS printing on the user interface.
4947 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Added new argument to the WHOWAS command reply, the real name.
4950 It is an optional argument. Updated the protocol specs.
4952 * Added SilcIDCacheDestructor callback that is registered when
4953 the SilcIDCache is allocated. The callback is called when
4954 an cache entry in the ID Cache expires, or is purged from the
4955 cache. Added into lib/silccore/idcache.[ch].
4957 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4958 to destruct the client entries when the cache entry expires.
4959 Other ID Cache's in server and in the client library ignores
4962 * If the ID Cache entry's `expire' field is zero then the entry
4963 never expires. Added boolean `expire' argument to the
4964 silc_idcache_add function in the lib/silccore/idcache.[ch].
4965 If it is TRUE the default expiry value is used.
4967 * Added silc_server_free_client_data_timeout that is registered
4968 when client disconnects. By default for 5 minutes we preserve
4969 the client entry for history - for WHOWAS command.
4971 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4973 * Added support to the server to enforce that commands are not
4974 executed more than once in 2 seconds. If server receives
4975 commands from client more frequently, timeout is registered
4976 to process the commands. Affected file silcd/command.c.
4977 Added new function silc_server_command_process_timeout.
4979 * Changed NICK_NOTIFY handling in client library to check that
4980 if the client's nickname was changed, so there is no need to
4981 resolve anything from the server.
4983 * Removed error printing from the WHOIS and IDENTIFY commands.
4984 If error occurs then it is ignored silently in the client library.
4985 The application, however, may map the received error to
4986 human readable error string. The application currently maps
4987 the NO_SUCH_NICKNAME error to string.
4989 * Made the command status message public to the application. Moved
4990 them from lib/silcclient/command_reply.c to
4991 lib/silcclient/command_reply.h. The application can map the
4992 received command status to the string with the
4993 silc_client_command_status_message function.
4995 * Added check to the server to check that client's ID is same
4996 as the Source ID in the packet the client sent. They must
4999 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * Added dist-bzip hook to the Makefile.am to make bzip2
5002 compressed distributions.
5004 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5006 * Server now enforces the maximum length for the nickname and
5007 the channel as protocol specification dictates. 128 bytes for
5008 nickname and 256 bytes for channel name.
5010 * Moved the WHOIS printing to the application. The client libary
5011 does not print out the WHOIS information anymore, the application
5012 must do it. Renamed silc_client_command_reply_whois_print to
5013 the silc_client_command_reply_whois_save.
5015 The client's idle time is also sent to the application now, and
5016 the idle is shown on screen.
5018 * Added silc_client_command_reply_identify_save to save the
5019 received IDENTIFY entries.
5021 * Do not check for channel private keys in message sending and
5022 reception if the channel does not have the PRIVKEY mode set.
5023 Affected file lib/silclient/client_channel.c.
5025 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5028 just surfaced after chaning the JOIN procedure.
5030 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5032 * Added silc_client_get_clients_by_list to get client entries
5033 from Client ID list, that is returned for example by JOIN
5034 and USERS command replies. The application should use this
5035 function for example when JOIN command reply is received to
5036 resolve the clients already on the channel (library does not
5037 do that anymore as USERS command reply is not used in the JOIN
5038 procedure anymore). Affected files lib/silcclient/silcapi.h and
5039 lib/silcclient/idlist.c.
5041 * JOIN command reply and USERS command reply returns now SilcBuffer
5042 pointers instead of unsigned char pointers when returning
5043 the client list and mode list.
5045 * Added <Client ID> argument to the JOIN command reply, mainly
5046 for the server to identify for which client the command was
5047 originally sent. Updated protocol specs accordingly.
5049 * Added SilcDlist private_key pointer to the SilcChannelEntry
5050 in the client to support the channel private keys. Affected
5051 file is lib/silcclient/idlist.h.
5053 * Added SilcChannelPrivateKey argument to the function
5054 silc_client_send_channel_message so that application can choose
5055 to use specific private ke if it wants to. If it is not provided,
5056 the normal channel key is used, unless private keys are set.
5057 In this case the first (key that was added first) is used
5058 as the encryption key.
5060 * Implemented the support for channel private key handling.
5061 Implemented the following functions:
5063 silc_client_add_channel_private_key,
5064 silc_client_del_channel_private_keys,
5065 silc_client_del_channel_private_key,
5066 silc_client_list_channel_private_keys and
5067 silc_client_free_channel_private_keys
5069 Affected file lib/silcclient/client_channel.c.
5071 * Added the support for the private keys in the channel message
5072 sending and encryption and in the message reception and
5073 decryption. Affected funtions are
5074 silc_client_send_channel_message and silc_client_channel_message.
5076 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5078 * Added SKE's key verify callback to the client library's
5079 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5081 * Removed the statement that server (or router) must send USERS
5082 command reply when joining to the channel so that the client
5083 knows who are on the channel. Instead, the client list and
5084 client's mode list is now sent in the JOIN command reply to the
5085 client who joined channel. This is better solution.
5087 * Added function silc_server_get_users_on_channel and function
5088 silc_server_save_users_on_channel to the silcd/server.[ch].
5090 * Removed function silc_server_command_send_users from the
5093 * Do not show topic on the client library anymore. The topic is
5094 sent in the command reply notify to the application and the
5095 application must show the topic now.
5097 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5099 * Added client searching by nickname hash into the IDENTIFY and
5100 WHOIS commands in the server as they were clearly missing from
5101 them. Affected file is silcd/command.c.
5103 * Fixed a bug in private message receiving in the client library.
5104 The remote ID was freed and it wasn't supposed, now it is
5107 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * Minor fix to the channel payload; allocate the data area, as it
5110 needs to be of specific length.
5112 * If the key agreement port is zero then the operating
5113 system will define the bound port. Affected files are
5114 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5116 * Added new function silc_channel_payload_decrypt into the file
5117 lib/silccore/silcchannel.[ch].
5119 * Moved the channel message etc, check from silc_packet_decrypt
5120 to applications. The library calls now a generic
5121 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5122 when the packet is either normal or special. This was done to
5123 allow more wide range of checking that was not allowed when
5124 the code was in library. Now applications can do virtually any
5125 checks to the packet and return to the library the decision how
5126 the packet should be processed. Affected files are
5127 lib/silccore/silcpacket.[ch].
5129 Added silc_server_packet_decrypt_check to the server and
5130 silc_client_packet_decrypt_check to the client library.
5132 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5133 to send with specified source and destination information.
5135 * Channel message delivery between routers was broken after the
5136 channel key distribution was fixed earlier. The channel key
5137 was used be to distributed to other routers as well which is not
5138 allowed by the protocol. Now this is fixed and channel keys
5139 really are cell specific and the channel message delivery between
5140 routers comply with the protocol specification.
5142 * Fixed various commands in server to check also the global list
5143 for the channel entry and not just the local list. The affected
5144 file silcd/command.c.
5146 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5148 * Added assert()s to buffer formatting and unformatting routines
5149 to assert (if --enable-debug) when error occurs. Affected
5150 file: lib/silcutil/silcbuffmt.c.
5152 * Changed to auto-reconnect to check whether the remote host is
5153 router and register the re-connect timeout if it is. It used
5154 to check that whether we are normal server, but router must do
5155 auto-reconnect with another router as well. Affected file
5158 * Removed the [<key len>] option from CMODE command as the cipher
5159 name decides the key length, nowadays. See the defined ciphers
5160 from the protocol specification.
5162 * Added [<hmac>] option to the CMODE command to define the HMAC
5163 for the channel. Added SILC_CMODE_HMAC channel mode.
5165 * Added [<hmac>] option for the JOIN command so that user can
5166 select which HMAC is used to compute the MACs of the channel
5169 * Added Hmac field to the Channel Message Payload. The integrity
5170 of plaintext channel messages are now protected by computing
5171 MAC of the message and attaching the MAC to the payload. The
5172 MAC is encrypted. Now, it is clear that this causes some
5173 overhead to the size of the packet but rationale for this is that
5174 now the receiver can verify whether the channel message decrypted
5175 correctly and also when private keys are set for the channel the
5176 receiver can decrypt the packet with several keys and check from
5177 the MAC which key decrypted the message correctly.
5179 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5180 lib/silccrypt/silccipher.[ch].
5182 * Added silc_hash_len to return the digest length into the
5183 lib/silcrypt/silchash.[ch].
5185 * Rewrote parts of Silc Channel Payload interface in the
5186 lib/silccore/silcchannel.[ch]. The encode function now also
5187 encrypts the packet and parse function decrypts it.
5189 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Fixed a minor formatting bug in the SKE's key material processing.
5192 It actually might have processed the keys wrong way resulting
5195 * Redefined the mandatory HMAC algorithms and added new algorithms.
5196 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5197 and hmac-md5 truncated to 96 bits. The mandatory is now
5198 hmac-sha1-96. Rest are optional (including the one that used
5199 to be mandatory). Rationale for this is that the truncated HMAC
5200 length is sufficient from security point of view and can actually
5201 make the attack against the HMAC harder. Also, the truncated
5202 HMAC causes less overhead to the packets. See the RFC2104 for
5205 * Added new [hmac] configuration section. The SKE used to use
5206 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5207 is of course wrong. The official names that must be proposed in
5208 the SKE are the ones defined in the protocol specification
5209 (hmac-sha1-96 for example). The user can configure any hmac
5210 using any hash function configured in the [hash] section. At
5211 least, the mandatory must be configured.
5213 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5215 * Added HMAC list to the SKE proposal list. It has now both
5216 hash algorithm list and HMAC list. This makes the protocol
5217 incompatible with previous versions. The SKE now seems to work
5218 the way it is supposed to work, for the first time actually.
5220 * Defined plain Hash algorithms to the protocol specification.
5223 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5225 * Implemented support for key agreement packets into the server.
5226 Added functions silc_server_key_agreement and
5227 silc_server_send_key_agreement. Other than these functions,
5228 server has nothing to do with this packet.
5230 * Added support for private message key packets into the server.
5231 Added functions silc_server_private_message_key and
5232 silc_server_send_private_message_key.
5236 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5237 called in the protocol's final callback instead in the END
5238 protocol state. This makes a little more sense and in the same
5239 time in client we can use the same protocol routines for normal
5240 key exchange and to key agreement packet handling as well.
5242 * Added to both client's and server's KE protocol context the
5243 SilcSKEKeyMaterial pointer to save the key material. We will
5244 bring the key material to the protocol's final callback by doing
5245 this. The final callback must free the key material.
5247 * Added SKE's packet_send callback into client's KE protocol
5248 context so that the caller can choose what packet sending function
5249 is used. This way we can use different packet sending when
5250 doing normal SKE when doing key agreement packet handling (in
5251 the key agreement packet handling we do not want to encrypt
5254 * Implemented the responder side of the key agreement routines
5255 in the client. The client can now bind to specified port and
5256 accept incoming key negotiation. The key material is passed
5257 to the application after the protocol is over.
5259 * Implemented the processing of incoming Key Agreement packet
5260 in the client. Added function silc_client_key_agreement to
5263 * Implemented the intiator side of the key agreement routines
5264 in the client. The client can now initiate key agreement with
5265 another remote client. The key material is passed to the
5266 application after the protocol is over.
5268 * Created client_keyagr.c to include all the key agreement
5271 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5272 SILC_TASK_CALLBACK except that it is not static.
5274 * Created client_notify.c and moved the Notify packet handling
5275 from the client.[ch] into that file.
5277 * Created client_prvmsg.c and moved all private message and
5278 private message key routines from the client.[ch] into that file.
5280 * Create client_channel.c and moved all channel message and
5281 channel private key routines from the client.[ch] into that file.
5283 * Changed silc_client_get_client_by_id_resolve to resolve with
5284 WHOIS command instead of IDENTIFY command, in the file
5285 lib/silclient/idlist.c.
5287 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5289 * Implemented the SKE's responder side to the Client library.
5291 * When FAILURE is received to the protocol do not trust it
5292 blindly. Register a timeout to wait whether the remote closes
5293 the connection as it should do it, only after that process the
5294 actual failure. This was changed to both client and server.
5296 * Added client_internal.h to include some of the structures
5297 there instead of client.h in lib/silcclient/.
5299 * Added function silc_task_unregister_by_callback to unregister
5300 timeouts by the callback function.
5302 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5304 * Some "Incomplete WHOIS info" errors has been appearing on the
5305 log files. Took away the entry->userinfo check from WHOIS
5306 reply sending. The entry->userinfo is now " " if client did not
5307 provide one. I thought this was fixed earlier but something
5308 is wrong still. Let's see if the error still appears.
5310 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5312 * Fixed a minor bug in the login when the channel key is
5313 re-generated in the server. It used to generate the key in
5314 wrong order and thus caused problems in the channel traffic.
5316 * Fixed a minor bug in channel key distsribution after
5317 KICK command. The key was not sent to the router even though
5320 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5322 * Added silc_ske_process_key_material_data as generic routine
5323 to process any key material as the SILC protocol dictates. The
5324 function is used by the actual SKE library but can be used by
5325 applications as well. This relates to the private message keys
5326 and the channel private keys since they must be processed the
5327 same way the normal SILC session keys. The protocol dictates
5328 this. Affected files: lib/silcske/silcske.[ch].
5330 Added also silc_ske_free_key_material to free the
5331 SilcSKEKeyMaterial structure.
5333 * Defined silc_cipher_set_key function to set the key for
5334 cipher without using the object's method function. The affected
5335 files: lib/silccrypt/silccipher.[ch].
5337 * Implemented silc silc_client_add_private_message_key,
5338 silc_client_add_private_message_key_ske,
5339 silc_client_del_private_message_key,
5340 silc_client_list_private_message_keys and
5341 silc_client_free_private_message_keys functions in the
5344 Added functions silc_client_send_private_message_key to send
5345 the Private Message Key payload and silc_client_private_message_key
5346 to handle incoming Private Message Key payload.
5348 * Added Cipher field to the Private Message Key payload to set
5349 the cipher to be used. If ignored, the default cipher defined
5350 in the SILC protocol (aes-256-cbc) is used.
5352 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5354 * Removed lib/silcclient/ops.h file.
5356 Redefined parts of the SILC Client Library API. Created new
5357 file silcapi.h that deprecates the ops.h file and defines the
5358 published Client Library API. Defined also private message key
5359 API and channel private key API into the file.
5361 This is the file that the application must include from the
5362 SILC Client Library. Other files need not be included by
5363 the application anymore.
5365 * Added new key_agreement client operation callback and also
5366 defined the Key Agreement library API for the application.
5368 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5370 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5371 is used by clients to request key negotiation between another
5372 client in the SILC network. If the negotiation is started it
5373 is performed using the SKE protocol. The result of the
5374 negotiation, the secret key material, can be used for example
5375 as private message key.
5377 Implemented the Key Agreement payload into the files
5378 lib/silccore/silauth.[ch].
5380 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5382 * Redefined ciphers for the SILC protocol. Added some new ciphers
5383 and defined the key lengths for the algorithms. Changed the
5384 code accordingly. The default key length is now 256 bits.
5386 * Fixed SKE key distribution function silc_ske_process_key_material
5387 when the key length is more than 128 bits. The default key
5388 length in SILC is now 256 bits.
5390 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5391 to indicate unsupported algorithm.
5393 * Renamed rijndael.c to aes.c and all functions as well.
5395 * Fixed a long standing channel key setting bug in client library.
5396 Weird that it has never surfaced before.
5398 * Fixed bug in channel deletion. If the entire channel is removed
5399 then it must also delete the references of the channel entry
5400 from the client's channel list as the client's channel entry and
5401 the channel's client entry share same memory.
5403 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5405 * Implemented CONNECT and SHUTDOWN commands in the client.
5407 * Implemented CLOSE command to the client.
5409 * Added the function silc_idlist_find_server_by_name into the
5410 files silcd/idlist.[ch].
5412 Added the function silc_idlist_find_server_by_conn into the
5413 files silcd/idlist.[ch].
5415 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5417 * DIE command was renamed to SHUTDOWN. Updated the both code
5420 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5421 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5423 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5426 * Added function silc_server_create_connection function to create
5427 connection to remote router. My server implementation actually
5428 does not allow router to connect to normal server (it expects
5429 that normal server always initiates the connection to the router)
5430 so the CONNECT command is only good for connecting to another
5433 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5435 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5436 or some other client was kicked from the channel.
5438 Implemented the handling of the notify type to both client
5441 Implemented silc_server_send_notify_kicked to send the KICKED
5442 notify. It is used to send it to the server's primary router.
5444 * Implemented the KICK command into server and client.
5446 * Added `query' argument to the silc_idlist_get_client function
5447 to indicate whether to query the client from server or not if
5450 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5451 to indicate that the client is not channel founder.
5455 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Removed the rng context from SilcPacketContext structure and
5458 changed that the packet routine uses the Global RNG API.
5460 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5462 * Added support for quit message that client can "leave" on the
5463 channel when it quits the SILC. It is ditributed inside the
5464 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5466 Added silc_server_free_client_data that will take the
5467 signoff message as argument.
5469 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5471 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5473 * Updated parts of the protocol specification to keep it up
5476 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5479 payloads in one packet.
5481 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5482 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5483 use now the new List flag.
5485 * Also deprecated the following packet types: REPLACE_ID,
5486 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5488 * Added list support for Notify packet in server.
5490 * Added silc_server_send_notify_channel_change to send the
5491 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5492 the silc_server_send_replace_id.
5494 * Added silc_server_send_notify_nick_change to send the
5495 NICK_CHANGE notify type. Deprecates the function
5496 silc_server_send_replace_id.
5498 * Added silc_server_send_notify_join to send the JOIN notify type.
5499 Deprecates the function silc_server_send_new_channel_user.
5501 * Added silc_server_send_notify_leave to send LEAVE notify type.
5502 Deprecates the function silc_server_send_remove_channel_user.
5504 * Added silc_server_send_notify_cmode and
5505 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5506 types. Deprecates the silc_server_send_set_mode function.
5508 * Added SERVER_SIGNOFF notify type to indicate that server has
5509 quit. This means that all clients on the channel from that
5510 server will drop. This can be also used when netsplit happens.
5512 Deprecated REMOVE_ID packet type since it is not needed anymore
5515 Added silc_server_send_notify_server_signoff to send the
5516 SERVER_SIGNOFF notify type. Deprecates the function
5517 silc_server_send_remove_id.
5519 Added also silc_server_send_notify_signoff to send the
5520 SIGNOFF notify type.
5522 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5523 SILC protocol from this day on. Changed the protocol
5524 specification as well.
5526 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5527 notify type. It is used between routers to notify about
5528 topic changes on a channel.
5530 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5533 * Partly updated the protocol specification to comply with the
5534 changes now made. It is still though a bit outdated.
5536 * The JOIN notify type now takes one extra argument <Channel ID>.
5537 The packet used to be destined to the channel but now the
5538 JOIN type may be sent as list thus it is impossible to
5539 destine it to any specific channel. By adding this argument
5540 it is again possible.
5542 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5544 * Added CREDITS file. The CHANGES and CREDITS file will appear
5545 in the distribution as well.
5547 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5550 types in the server's silcd/packet_receive.c.
5552 * Implemented CMODE and CUMODE to work in router environment.
5554 * Fixed minor encoding and decoding buglet from the
5555 lib/silccore/silcmode.c.
5557 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5560 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5562 * Changed all SilcConfigServer* and silc_config_server* to
5563 SilcServerConfig* and silc_server_config*, respectively.
5566 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5568 * Associated the ID (client or server ID) to the Authentication
5569 Payload to avoid any possibility of forging. Updated the
5570 protocol specification and the code accordingly.
5572 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5574 * The RSA key length is now save to the RsaKey context in the
5575 key generation process in lib/silccrypt/rsa.c. The key length
5576 is now used to figure out the maximum size of the block allowed
5577 to be encrypted/signed.
5579 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5580 is equivalent to the silc_mp_mp2bin but does not allocate any
5583 * Changed silc_mp_mp2bin API to take length argument. If it is
5584 non-zero then the buffer is allocated that large. If zero, then
5585 the size is approximated using silc_mp_sizeinbase, which however
5588 * Created Global RNG API which is global RNG that application can
5589 initialize. After initializing, any routine anywhere in the
5590 code (including library) can use RNG without allocating a new
5591 RNG object. This was done to allow this sort of use of the
5592 RNG in code that has no chance to allocate RNG object. All
5593 applications currently allocate this and many routines in the
5594 library use this. Affected file lib/silccrypt/silcrng.[ch].
5596 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5597 it to use the Global RNG API.
5599 * Defined Authentication Payload into protocol specification that
5600 is used during SILC session to authenticate entities. It is
5601 used for example by client to authenticate itself to the server
5602 to obtain server operator privileges.
5604 Implemented this payload into the lib/silccore/silcauth.[ch].
5605 Implemented also routines for public key based authentication
5606 as the new protocol specification dictates.
5608 Moved definitions of different authentication methods from
5609 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5611 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5612 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5613 silc_pkcs_verify_with_hash functions into the file
5614 lib/silccrypt/silcpkcs.[ch].
5616 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5618 * The client entry's userinfo pointer must be always valid.
5619 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5620 will fail since it requires the userinfo. Now, the userinfo
5621 is allocated as "" if actual userinfo does not exist. Actually,
5622 it must exist and it is totally Ok to drop client connections
5623 that does not announce the userinfo. However, we will make
5624 this workaround for now.
5626 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5627 to return the remote port by socket.
5629 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5631 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5632 SILC_SERVER_PENDING_EXEC and added an new macro
5633 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5634 data or when error occurs while processing the pending command.
5636 Added new argument `destructor' into silc_server_command_pending
5637 and to the SilcServerCommandPending object. This destructor is
5638 now called after calling the pending callback or if error occurs
5639 immediately. If error occurs the actual pending callback won't
5640 be called at all - only the destructor. The destructor may be
5641 NULL if destructor is not needed.
5643 All this applies for client library code as well. Similar
5644 changes were made there as well for the pending commands.
5646 In the client, the application must now allocate the
5647 SilcClientCommandContext with the silc_client_command_alloc
5650 * Added reference counter to the SilcServerCommandContext. Added
5651 function silc_server_command_alloc and silc_server_command_dup
5654 Same type of functions added to the client library for the same
5657 * Removed the cmd_ident from IDListData away since it is now
5658 global for all connections. It is the command identifier used
5659 in command sending and with pending commands. The affected file
5662 * Added reference counter to the SilcSocketConnection objecet to
5663 indicate the usage count of the object. The object won't be
5664 freed untill the reference counter hits zero. Currently only
5665 server uses this, and client ignores it. The client must be
5666 set to use this too later. The affected files are
5667 lib/silccore/silcsockconn.[ch]. Added also the function
5668 silc_socket_dup to increase the reference counter.
5670 This was mainly added because it is possible that the socket
5671 is removed underneath of pending command or other async
5672 operation. Now it won't be free'd and proper DISCONNECTING
5673 flags, etc. can be set to avoid sending data to connection that
5674 is not valid anymore.
5676 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5677 the connection. After that it sets SILC_SET_DISCONNECTED.
5678 It is, however, possible that the socket data is not still freed.
5679 The silc_server_packet_process now checks that data is not
5680 read or written to connection that is DISCONNECTED. The socket
5681 get's freed when the reference counter hits zero.
5683 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5685 * Changed the client operation API: channel_message operation's
5686 `sender' is now the client entry of the sender, not the nickname
5687 and the `channel' is the channel entry, not the channel name.
5689 In the private_message operation the `sender' is now also the
5690 client entry of the sender not the nickname.
5692 Affected file is lib/silcclient/ops.h and all applications
5693 using the client operations.
5695 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5697 * Moved the calling of ops->connect() from connect_to_server_final
5698 into receive_new_id functin since that is the point when the
5699 client is actually allowed to send traffic to network. The
5700 affected file is lib/silcclient/client.c.
5702 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5704 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5705 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5706 (if needs broadcasting) instead of broadcasting the packets one
5707 by one which would make a burst in the network traffic.
5709 * Added `broadcast' argument to the functions in silcd/server.[ch]
5710 silc_server_create_new_channel[_with_id] to indicate whether
5711 to send New Channel packet to primary router.
5713 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5715 * Added new function into the silcd/server.[ch] files:
5716 silc_server_create_new_channel_with_id to create new channel with
5717 already existing Channel ID.
5719 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5720 lib/silccore/silcpacket.h. This packet is used t send list of
5721 Set Mode payloads inside one packet. Server uses this to set
5722 the modes for the channels and clients on those channels, that it
5723 announced to the router when it connected to it. The protocol
5724 specification has been updated accordingly.
5726 * The silc_server_new_channel did not handle the packet coming
5727 from normal server as it normally does not send that. However,
5728 when it announces its channels it does send it. Implemented
5729 the support for that.
5731 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5732 into the file lib/silccore/id.h.
5734 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5736 * Fixed memory leaks in the functions silc_idlist_del_client,
5737 silc_idlist_del_channel and silc_idlist_del_server in the file
5738 silcd/idlist.c. All of those leaked like a sieve.
5740 * Fixed some small memory leaks in the client's function
5741 silc_client_notify_by_server.
5743 * Added functions into silcd/server.c: silc_server_announce_clients,
5744 silc_server_announce_channels and silc_server_announce_server.
5745 These functions are used by normal and router server to announce
5746 to its primary router about clients, channels and servers (when
5747 router) that we own. This is done after we've connected to the
5750 These functions effectively implements the following packet types:
5751 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5752 and SILC_PACKET_NEW_ID_LIST.
5754 * Added new functions into the silcd/packet_receive.[ch]:
5755 silc_server_new_id_list, silc_server_new_channel_list and
5756 silc_server_new_channel_user_list to handle the incoming
5757 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5759 * Added support of changing Channel ID in the function
5760 silc_server_replace_id. If the server that announces a channel
5761 to the router already exists in the router (with same name but
5762 with different Channel ID), router is responsible to send
5763 Replace ID packet to the server and force the server to change
5764 the Channel ID to the one router has.
5766 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5767 client that the Channel ID has been changed by the router. The
5768 normal server sends this to the client. Client must start using
5769 the new Channel ID as the channel's ID.
5771 Implemented handling of this new type into lib/silcclient/client.c
5772 into the function silc_client_notify_by_server.
5774 * Added new function silc_idlist_replace_channel_id into the files
5775 silcd/idlist.[ch] to replace the Channel ID.
5777 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5779 * Call silc_server_command_identify_check always when processing
5780 the IDENTIFY command in silcd/command.c
5782 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5784 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5785 send keepalive packets. The packet can be sent by clients,
5786 servers and routers.
5788 Added function silc_socket_set_heartbeat into the file
5789 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5790 If not set, the heartbeat is not performed. The actual
5791 heartbeat is implemented in the low level socket connection
5792 library. However, application is responsible of actually
5795 Added silc_server_send_heartbeat to send the actual heartbeat
5796 packet into silcd/packet_send.[ch]. Server now performs
5797 keepalive with all connections.
5799 * Added silc_task_get_first function into lib/silcutil/silctask.c
5800 to return the timeout task with shortest timeout. There was a bug
5801 in task unregistration that caused problems. TODO has been
5802 updated to include that task system must be rewritten.
5804 * The client library will now resolve the client information when
5805 receiving JOIN notify from server for client that we know but
5806 have incomplete information.
5808 * Rewrote parts of silc_server_remove_from_channels and
5809 silc_server_remove_from_one_channel as they did not remove the
5810 channel in some circumstances even though they should've.
5812 * Encryption problem encountered in server:
5814 The LEAVE command used to send the Channel Key packet to the
5815 router immediately after generating it. However, the code
5816 had earlier sent Remove Channel user packet but not immediately,
5817 ie. it was put to queue. The order of packets in the router
5818 was that Channel Key packet was first and Remove Channel User
5819 packet was second, even though they were encrypted in the
5820 reverse order. For this reason, MAC check failed. Now, this
5821 is fixed by not sending the Channel Key packet immediately but
5822 putting it to queue. However, this is more fundamental problem:
5823 packets that are in queue should actually not be encrypted
5824 because packets that are sent immediately gets encrypted
5825 actually with wrong IV (and thus MAC check fails). So, packets
5826 that are in queue should be encrypted when they are sent to
5827 the wire and not when they put to the queue.
5829 However, the problem is that the current system has not been
5830 designed to work that way. Instead, the packet is encrypted
5831 as soon as possible and left to the queue. The queue is then
5832 just purged into wire. There won't be any fixes for this
5833 any time soon. So, the current semantic for packet sending
5836 o If you send packet to remote host and do not force the send
5837 (the packet will be in queue) then all subsequent packets to the
5838 same remote host must also be put to the queue. Only after the
5839 queue has been purged is it safe again to force the packet
5842 o If you send all packets immediately then it safe to send
5843 any of subsequent packets through the queue, however, after
5844 the first packet is put to queue then any subsequent packets
5845 must also be put to the queue.
5847 Follow these rules and everything works fine.
5849 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5851 * Added new function silc_server_remove_clients_by_server to
5852 remove all client entries from ID list when the server connection
5853 is lost. In this case it is also important to invalidate all
5854 client entires as they hold the invalid server entry. This
5855 fixes fatal bug when server has lost connection and will reconnect
5858 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5860 * Made some sanity checks to silc_server_daemonise like to check
5861 whether the requested user and group actually exists.
5863 * Added sanity check to SKE's silc_ske_responder_finish to check
5864 that the public and private key actually is valid.
5866 * Invalidate the client's nickname when receiving Replace ID
5867 packet and the Client ID is being replaced. This means that the
5868 server will query the nickname if someone needs it (client)
5871 * Sort the ID Cache in client library when the ID Cache data
5872 has changed (needs sorting).
5874 * Do not allow for SILC client to create several connections to
5875 several servers. The client does not support windows right now
5876 and generating multiple connections causes weird behaviour.
5878 Irssi-silc client does support windows and can handle several
5879 connections without problems, see: www.irssi.org and SILC plugin.
5881 * Fixed some places where client was added to the IDList. The
5882 rule of thumb is following (in order to get everything right):
5883 If the client is directly connected local client then the
5884 `connection' argument must be set and `router' argument must be
5885 NULL to silc_idlist_add_client function. If the client is not
5886 directly connected client then the `router' argument must
5887 bet set and the `connection' argument must be NULL to the
5888 silc_idlist_add_client function.
5890 * The funtion silc_server_packet_send_local_channel actually did
5891 not check whether the client was locally connected or not. It
5892 does that now. Fixed a bug related to LEAVE command.
5894 * Fixed Remove Channel User payload parsing bug in server's
5895 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5897 * The server's silc_server_save_channel_key now checks also the
5898 global ID list for the channel as it might not be in the local
5899 list. Fixed a bug related to LEAVE command.
5901 * Is this the end of the [<unknown>] buglet that has been lurking
5902 around for a long time? A little for loop fix in server's
5903 silc_server_command_whois_parse that is used by both IDENTIFY
5904 and WHOIS command. At least, this was a clear bug and a cause
5905 of one type of [<unknown>] buglet.
5907 * WHOIS and IDENTIFY commands call the function
5908 silc_server_command_[whois/identify]_check function even if
5909 we are not router server.
5911 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * Added --with-gmp configuration option. If set the GMP
5914 is always compiled in the SILC source tree. If not set then
5915 it is checked whether the system has the GMP3 installed. If
5916 it has then the GMP won't be compiled (the system's headers
5917 and library is used), if it doesn't have it then the GMP is
5918 compiled in the SILC source tree.
5920 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5922 * Changed RSA private exponent generation to what PKCS #1
5923 suggests. We try to find the smallest possible d by doing
5924 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5925 not security fix but optimization.
5927 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5929 * Added new config entry [Identity] to fork the server and run
5930 it as specific user and group. A patch from Bostik.
5932 * Imported Dotconf configuration library into lib/dotconf.
5933 This will be used to create the SILC configuration files later.
5934 It will appear in the distsribution after this commit.
5936 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5938 * A big code auditing weekend happening. Auditing code for
5939 obvious mistakes, bugs and errors. Also, removing any code
5942 Removed files for being obsolete:
5944 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5945 inline in the file lib/silcutil/silcbuffer.h)
5947 o lib/silcutil/silcbufutil.c (the header has inline versions)
5949 Changed code to fix possible error conditions:
5951 o The buffer formatting routines now check that the destination
5952 buffer really has enough space to add the data. This applies for
5953 both buffer formatting and unformatting
5954 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5955 unformatting was changed to accomodate following rules:
5956 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5957 sent to the function while XXX_*STRING will not allocate or copy
5958 the data into the buffer. Instead it sets the pointer from the
5959 buffer into the pointer sent as argument (XXX_*STRING used to
5960 require that the pointer must be allocated already). This change
5961 makes this whole thing a bit more consistent and more optimized
5962 (note that the data returned in the unformatting with XXX_*STRING
5963 must not be freed now). The routines return now -1 on error.
5965 o Tried to find all code that use buffer_format and buffer_unformat
5966 and added return value checking to prevent formatting and
5967 especially unformatting errors and possible subsequent fatal
5970 o Changed ske->x and ske->KEY to mallocated pointers in
5971 lib/silcske/silcske.h. Fixed possible data and memory leak.
5973 o Added return value checking to all *_parse* functions. Fixed
5974 many memory leaks as well.
5976 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5977 so that buffer overflows would not happen. All code now also
5978 checks the return value as it can fail.
5980 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5982 * Added reconnection support to server if the normal server looses
5983 its connection to the router (for example if router is rebooted).
5984 The server performs normal reconnection strategy implemented
5985 to the server. Affected file silcd/server.c.
5987 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5989 * Added new packet type SILC_PACKET_SET_MODE that is used to
5990 distribute the information about changed modes (for clients,
5991 channels and clients channel modes) to all routers in the
5992 network. Updated the protocol specification accordingly.
5994 Added functions into silcd/packet_send.c and
5995 silcd/packet_receive.c: silc_server_send_set_mode,
5996 silc_server_set_mode.
5998 Added new files silcmode.[ch] into lib/silccore that implements
5999 the encoding and decoding of Set Mode Payload. Added new type
6000 SilcSetModePayload. Moved the definitions of different modes
6001 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6003 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6005 * Oops, a little mistake in server's connection authentication
6006 protocol. The protocol is not ended with FAILURE but with
6007 SUCCESS if the authentication is Ok. :) Affected file is
6010 * Implemented NICK_CHANGE notify handling in server in the file
6011 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6012 the local clients on the channel. After the changing nickname
6013 in router environment snhould work and the [<unknown>] nickname
6014 should appear no more.
6016 The silc_server_replace_id function that receives the Replace ID
6017 payload now sends the NICK_CHANGE notify type also in the file
6018 silcd/packet_receive.c
6020 * Changed WHOIS and IDENTIFY command to support the maximum amount
6021 of arguments defined in protocol specs (3328 arguments). This
6022 fixed a bug that caused problems when there were more than three
6025 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6027 * Added extra parameter, command identifier, to the
6028 silc_client_send_command so that explicit command identifier
6031 Changed that ID list routines uses specific command identifier
6032 when sending WHOIS/IDENTIFY requests to the server so that they
6033 can be identified when the reply comes back.
6035 Affected files lib/silcclient/command.[ch],
6036 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6038 * Added `sender' argument to silc_server_packet_send_to_channel
6039 to indicaet the sender who originally sent the packet to us
6040 that we are now re-sending. Ignored if NULL. Affected file
6041 silcd/packet_send.[ch].
6043 * Added some server statistics support in silcd/server_internal.h
6044 SilcServerStatistics structure and around the server code. Also
6045 send some nice statistics information when client is connecting
6048 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6050 * Fixed channel ID decoding in server's JOIN command reply in
6051 silcd/command_reply.c
6053 * Fixed braodcasting of replace ID payload to not to send it if
6054 we are standalone server in silcd/packet_receive.c.
6056 * Fixed all channel message sending routines to not to send
6057 packets to clients that has router set, since they are routed
6058 separately in the same function earlier. Affects file
6059 silcd/packet_send.c and all channel packet sending functions.
6061 * In USERS reply, res_argv[i] are not allocated, the table
6062 is allocated. Thus changed that free the table, not its
6065 * In server's whois_check and identify_check if the client is
6066 locally connected do not send any WHOIS commands - they are not
6069 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6071 * Fixed some minor bugs in client when sending WHOIS command. The
6072 arguments was in wrong order.
6074 * Removed statis function add_to_channel from server in
6075 silcd/command.c that was previously used with the joining but
6078 * Tested USERS command in router environment successfully with two
6079 routers, two servers and two clients.
6081 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6083 * Reorganized the USERS command and command reply in client library
6084 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6085 When the command is given by user we register a pending command
6086 callback that will reprocess the command after the reply has been
6087 received from the server. When reprocessing the packet we then
6088 display the information. Thus, the USERS information is displayed
6089 now in the command callback instead of in the command reply
6090 callback. The processing of the command is same as previously
6091 when server has sent the command reply in the JOINing process.
6093 * Added to USERS command in silcd/command_reply.c to join the client,
6094 we didn't use to know about, to the channel after we've created
6095 a client entry for it. Also, for clienet we did know already still
6096 check whether it is on the channel or not and add it if not.
6098 * Removed silc_server_command_join_notify as the function and its
6101 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6103 * Changed the client's pending command handling to the same as the
6104 server's pending command handling. It is also now possible to
6105 execute command reply functions from other command reply
6106 function as the function callbacks for commands and command
6107 replies are one and same. The pending commands are not static
6108 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6109 in client connection context. Thus, pending commands are server
6110 connection specific as it is convenient.
6112 Changed the function silc_client_command_pending and
6113 silc_client_command_pending_del and added new function
6114 silc_client_command_pending_check. Removed the
6115 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6118 * Added cmd_ident, current command identifier, to the client
6119 connection context in lib/silcclient/client.h to keep track on
6120 command identifiers used in command sending. Client's command reply
6121 function handling now supports the mandatory command identifiers.
6123 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6124 funtions in client to fully support pending command callbacks.
6126 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6127 as one of the arguments to the application in the command reply
6130 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6131 before first releasing SILC but came back. Now it is removed again
6132 and should come back nomore. The FORWARDED flag was used only
6133 by the JOINing procedure by forwarding the command packet to router.
6134 Now, the JOINing procedure has been changed to more generic (due
6135 to various router environment issues) and FORWARDED is not needed
6136 anymore for anything. The protocol specification is yet to be
6139 Now, removed silc_server_packet_forward from server and the flag
6140 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6142 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6144 * Renamed NAMES command to USERS command. The NAMES was named that
6145 due to historical reasons. Now it is renamed. Also, rewrote
6146 parts of the USERS command. The nickname list is not sent anymore
6147 by the server. Only Client ID and mode lists are sent in the USERS
6148 command. Changed this also to the protocol specification.
6150 The client now resolves the names and stuff after it receives
6151 the USERS list from the server when joining to the channel.
6153 * WHOIS and IDENTIFY commands has been changed to support multiple
6154 Client ID's per command. One can now search for multiple users
6155 in the network by sending only one WHOIS or IDENTIFY command.
6156 Changed the code and the protocol specifications.
6158 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6159 uses silc_server_command_whois_parse to parse the request. */
6161 * If normal server, do not parse the WHOIS and IDENTIFY requests
6162 before sending it to the router. Saves some time.
6164 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * Fixed JOIN command on client library. Wrong number of arguments
6167 used to crash the client.
6169 * Added silc_server_channel_has_global function to check whether
6170 channel has global users or not.
6172 * Added silc_server_channel_has_local function to check whether channel
6173 has locally connected clients on the channel.
6175 * The silc_server_remove_from_one_channel now checks whether the
6176 channel has global users or not after given client was removed from
6177 the channel. It also checks whether the channel has local clients
6178 on the channel anymore. If it does not have then the channel entry
6179 is removed as it is not needed anymore.
6181 * The silc_server_notify now checks on JOIN notify whether the joining
6182 client is one of locally connected or global. If it is global then
6183 the channel has now global users on the channel and that is marked
6184 to the channel entry. Also, it now saves the global client to
6185 global list who is joining and JOINs it to the channel. This is
6186 for normal server, that is.
6188 Changed silc_server_send_notify_on_channel,
6189 silc_server_packet_relay_to_channel and
6190 silc_server_packet_send_to_channel check if we are normal server
6191 and client has router set (ie. global client) do not send the
6192 message to that client, as it is already routed to our router.
6194 * Implemented LEAVE notify type handling in silc_server_notify
6197 * Tested LEAVE command in router environment successfully. Tested
6198 with two routers, two servers and two clients.
6202 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6204 * Implemented SIGNOFF notify type handling in silc_server_notify
6207 * silc_server_remove_id now removes the client entry from all channels
6208 it has joined and thusly sends SIGNOFF notify type.
6210 * Rewrote the NAMES list generation in server by removing two excess
6211 loops. The lists are created now inside one loop.
6213 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6215 * silc_server_remove_channel_user checks now also global list
6216 for channel and client.
6218 * silc_server_new_channel_user checks now both local and global
6219 list for channel and client. Fixed a bug in client id decoding.
6220 Used to decode wrong buffer.
6222 * silc_server_channel_message checks now both local and global
6223 list for channel entry.
6225 * Tested channel joining (hence JOIN) in router environment
6226 successfully. Tested with two routers, two servers and two
6229 * Tested channel message sending in router environment successfully.
6231 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6233 * Added silc_server_save_channel_key into server.[ch] to save the
6234 received channel key in Channel Key payload processing. It is
6235 also used in JOIN command reply handling.
6237 Equivalent function silc_client_save_channel_key added into
6238 client.[ch] into client library.
6240 * Changed JOIN command reply to send information whether the channel
6241 was created or not (is existing already) and the channel key
6242 payload. Changed protocol specs accordingly.
6244 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6245 the request was sent by ID and not by nickname. Crashed on
6248 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6250 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6251 now correctly save the received data.
6253 * silc_server_free_sock_user_data now notifies routers in the
6254 network about entities leaving the network.
6256 At the same time implemented functions silc_server_remove_id
6257 and silc_server_send_remove_id to receive and send REMOVE_ID
6258 packets. The packet is used to notify routers in the network
6259 about leaving entities. The ID removed will become invalid in
6262 * Added function silc_idlist_del_server into server. Removes and
6263 free's server entry from ID list.
6265 * silc_server_private_message function now checks, if we are router,
6266 that the destination ID really is valid ID, naturally.
6268 * In router when NEW_ID packet is received (for new client) the
6269 hash of the Client ID is saved in the ID Cache but the
6270 client->nickname is set to NULL, instead of putting the hash
6273 IDENTIFY command now also checks that client->nickname must be
6274 valid. If it is not if will request the data from the server who
6275 owns the client. Added new function
6276 silc_server_command_identify_check.
6278 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6279 to set the command to already allocated Command Payload.
6281 * Tested private message sending in router environment with two
6282 routers, two servers and two clients. Fixed minor bugs and now
6285 * Fixed segfault from client's NAMES command. Used to crash if
6288 * Forwarded packets must not be routed even if it is not destined
6289 to the receiver. Changed server code comply with this.
6291 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6293 * Added `require_reverse_mapping' boolean value to ServerParams
6294 structure. If TRUE (not default) the server will require that
6295 the connecting host has fully qualified domain name.
6297 If the reverse mapping is not required and hostname could not be
6298 found the IP address is used as hostname.
6300 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6302 * Implemented version string checking to both client and server.
6303 The check is incomplete currently due to the abnormal version
6304 strings used in development version of SILC.
6306 * Changed all command functions in server to use the new
6309 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6311 * Changed char *data to unsigned char *data in ID Cache system to
6312 support binary data as ID Cache data. Changed code to support
6313 binary data in lib/silccore/idcache.c.
6315 * Renamed silc_server_packet_relay_command_reply to
6316 silc_server_command_reply as it is normal packet receiving
6317 function. Rewrote the function to accept command replys for
6318 servers and not only for clients.
6320 * Mark remote router always as registered server if we are connecting
6321 to it. Otherwise, commands sent by the router to us are ignored.
6323 * All ID List find routines now returns the ID Cache Entry pointer
6324 as well if requested.
6326 * WHOIS command works now in router environment, tested with two
6327 routers, two servers and two clients.
6329 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6330 in router environment (as it is almost equivalent to WHOIS) but
6331 hasn't been tested thoroughly. Added new functions:
6333 silc_server_command_identify_parse
6334 silc_server_command_identify_send_reply
6335 silc_server_command_identify_from_client
6336 silc_server_command_identify_from_server
6338 * Disabled route cache adding because adding two different ID's with
6339 same IP replaces the old cache entry thus giving wrong route.
6340 The entry->router->connection is always the fastest route anyway
6341 so route cache may not be needed. Of course, new routes maybe
6342 established after receiving the ID when the entry->router->connection
6343 might not be anymore the most optimal.
6345 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6347 * Add route cache for received ID for fast routing.
6349 * Added silc_server_packet_route to route received packet on router
6350 that is not destined to us.
6352 * Renamed silc_server_get_route to silc_server_route_get.
6354 * Added id_string and id_string_len fields into SilcServer to
6355 include encoded ServerID for fast comparing without excess
6356 encoding of the ID's.
6358 * Cleaned up WHOIS command on server side. Added following static
6361 silc_server_command_whois_parse
6362 silc_server_command_whois_check
6363 silc_server_command_whois_send_reply
6364 silc_server_command_whois_from_client
6365 silc_server_command_whois_from_server
6367 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6368 arguments in command replies. All command functions should be
6369 updated to use this macro.
6371 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6373 * Minor typo fixes on command reply handling on server.
6375 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6377 * Added silc_server_command_add_to_channel internal routine to add
6378 the client to the channel after router has created the channel and
6379 sent command reply to the server.
6381 * Added generic silc_server_send_command to send any command from
6384 * Use static buffer with ID rendering instead of duplicating data.
6386 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6388 * Fixed a channel user mode bug when joining to a channel server gave
6389 everybody channel founder rights, oops.
6391 * We mark ourselves as the router of the incoming server connection
6392 if we are router ourselves. This way we can check in some packet
6393 sending functions whether it is locally connected server. For
6394 incoming router connections we put NULL.
6396 * For router sending packets locally means now always sending the
6397 packet cell wide; to local clients and local servers. For normal
6398 server sending packet locally means sending it to only local
6401 * Fixed the JOIN command to really work in router environment. If the
6402 channel is created it is always created by the router. Router is
6403 also responsible of making the initial joining to the channel,
6404 sending JOIN notify to the sending server and distributing
6405 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6406 does not exist server doesn't do anything else but forward the
6407 command to the router which performs everything.
6409 * Added silc_server_send_channel_key function to send the Channel Key
6412 * Added silc_server_create_channel_key to create new channel key. The
6413 channel key is now re-generated everytime someone joins or leaves
6414 a channel, as protocol dictates. Note: channel->key_len is the
6417 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6419 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6420 packet_receive.[ch] to separate packet sending and receiving
6421 routines. The server.[ch] now includes everything else including
6422 actual packet processing (writing and reading data) and other
6425 Renamed silc_server_private_message_send_internal to
6426 silc_server_send_private_message. The routine is still though
6427 used only to relay private messages as server does not send
6428 private messages itself.
6430 Renamed silc_server_new_channel to silc_server_create_new_channel
6431 and added new function sicl_server_new_channel that handles the
6432 incoming New Channel packet. Added also new sending function
6433 silc_server_send_new_channel to send New Channel Payload.
6435 * Added new function silc_server_notify to process incoming notify
6436 packet to the server/router. Server may then relay the notify
6437 to clients if needed.
6439 * Added new function silc_server_new_channel_user to process incoming
6440 New Channel User packet. Router will redistribute the packet and
6441 send JOIN notify to its local clients and locally connected servers
6442 if needed. Normal server will send JOIN notify to its local client
6443 on same channel when received this packet. Added also corresponding
6444 sending function silc_server_send_new_channel_user to sent the
6447 * Added boolean route argument to send_notif_to_channel and
6448 packet_send_to_channel functions to attempt to route the packet
6449 if it is TRUE and send only locally if it is FALSE.
6451 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6453 * silc_server_replace_id now broadcasts the received replace ID
6454 packet if it is not broadcast packet already. The router must
6455 broadcast to inform other routers about changed ID.
6457 * Added backpointer to server's router into SilcServer context in
6458 silcd/server_internal.h.
6460 * Fixed silc_server_packet_broadcast to send correct broadcast
6463 * The channel key is now distributed to the local client as soon
6464 as it is received from the router (in router environment) so that
6465 no other packet may be sent for the channel until client has
6468 * silc_server_remove_channel_user now broadcasts the received
6469 Remove Channel User packet if it is not broadcast packet already.
6470 The router must broadcast to inform other routers about removed
6473 * Added users field into SilcPacketContext that is a reference count
6474 of the context. One can increase the reference count by calling
6475 silc_packet_context_dup which is now changed to just increase the
6476 reference count instead of duplicating the data. The reference
6477 count is decresed by calling silc_packet_context_free that will
6478 free the data after the reference count hits zero.
6480 For now on the packet context and everything allocated into it
6481 (including the raw packet from network) must be freed by calling
6482 the new silc_packet_context_free function. Added also new function
6483 silc_packet_context_alloc that must be used now to allocate the
6484 context. This also means that if a routine is asynchronous from
6485 silc_[client/server]_packet_parse_type the packet context must
6486 be duplicated by calling silc_packet_context_dup. Otherwise it
6487 gets free'd after silc_[client/server]_packet_parse_type returns.
6488 Also, one must remember that if packet is duplicated then its
6489 reference count must be decresed by calling the free function as
6490 many times as it was duplicated.
6492 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6493 from both client and server.
6495 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6497 * Made joining to a channel working in router environment.
6499 * Cleaned up JOIN command on server side and create function
6500 silc_server_command_join_channel internal routine to make the
6503 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6505 * Changed silc_command_pending list to SilcDList. Also, added
6506 `ident' field to SilcServerCommandPending structure to identify
6507 the reply and to call correct callback.
6509 Added silc_server_command_pending_check function to replace the
6510 corresnponding macro. The silc_command_pending list is not
6513 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6514 to set identifier to previously allocated Command Payload. It
6515 is used to set identifier for command when resending Command
6518 * Added silc_command_payload_encode_payload to encode Command
6519 Payload buffer from SilcCommandPayload structure.
6521 * Added silc_argument_payload_encode_payload to encode Argument
6522 payload buffer from SilcArgumentPayload structure.
6524 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6526 * Changed WHOIS command to support router connection on server side.
6527 The whois request is always sent to router unless the server is
6528 standalone server. After server has received the reply from the
6529 router will it send the reply to the client.
6531 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6532 broadcast received broadcast packet. The function is used only
6533 by router. The broadcast packet is always sent to the router's
6536 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6537 render given ID to printable string, for log files for example.
6539 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6541 * Made basic router to router connections working. At least they
6542 can now connect to each other but nothing really works the way
6543 they are supposed - yet.
6545 * Added new initiator token to RouterConnection configuration
6546 file in silcd/serverconfig.[ch]. It is used to tell whether we
6547 are the initiator to the remote router or whether we'll expect
6548 the other end to connect.
6550 * Moved registering of listener task to silc_server_init, hence
6551 the server starts listenning as soon as it is run, even if it
6552 does not have connections to other routers. Let's see how well
6555 * Changed default connection retry timeouts for more suitable in
6558 * Removed cipher and such arguments from silc_idlist_add_client
6559 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6560 Added new function silc_idlist_add_data to add the keys and stuff
6563 * Added SilcIDListData structure and added it to SilcClientEntry
6564 and SilcServerEntry as their first field in the structure. This
6565 way we can explicitly cast the ID entries to the SilcIDListData
6566 structure and get common data for the entries. In past, we had
6567 to first check what type of connection it is and then cast it to
6568 correct ID entry type. Now, we can directly cast the opaque
6569 pointer to the SilcIDListData (no matter what ID entry it actually
6570 is) and get the data needed.
6572 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6574 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6575 in some circumstances even if threre were timeout tasks, though not
6576 IO tasks, but tasks anyway. Now fixed.
6578 * Defined SilcServerConnection structure to hold connection specific
6579 stuff about directly connected servers and routers. The definition
6580 is currently in silcd/server_internal.h. I thought about having
6581 a bit more important role fro this struct but for now it is used
6582 only when connecting to other server (or router actually).
6584 * Added connecting retry support in server when connecting to
6585 router(s). The retry feature implement exponential backoff
6586 algorithm. Also, added SilcServerParams structure to hold default
6587 parameters for server. For now, it include these retry settings
6588 and are hard coded. After server is moded to be as Silc Server
6589 Library this structure will be more important.
6591 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6593 * Changed client librarys channel->clients table to SilcList and
6594 changed code accordingly.
6596 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6598 * Changed client's channel table to SilcList and changed code
6599 accordingly. Also changed SilcChannelClientEntry to include back-
6600 pointer to the channel so that client entry can use that structure
6601 as list as well and we have fast cross-reference to the channel.
6602 This change dramatically decreased the complexity of channel
6603 handling with client entry and vice versa (removed one extra
6604 loop when searching for channel entry from many functions).
6606 * Changed server->sim from table to SilcDList and changed code
6609 * NAMES command can now be used from user interface. It will show
6610 the user list on the channel, neatly.
6612 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6613 Code now saves realname of the user if it becomes available.
6615 * Renamed configure.in to configure.in.pre and made ./prepare
6616 script to automatically add correct version string to
6617 configure.in which it creates from configure.in.pre.
6619 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6621 * NAMES command reply now shows users mode with the nickname when
6624 * Moved silc_client_ch[u]mode[_char] functions from
6625 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6626 place sucks, they are utility functions and should be in some
6629 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6631 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6634 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6638 * Added TRQ (efficient deque and list library) into lib/trq. This is
6639 a very good list library that is currently used in the SILC. Defined
6640 SilcList API over the library because I didn't like the API very
6641 much. See lib/trq/silclist.h for the API and examples of how to
6642 use the API. Fixed various places in the code to use the new
6643 SilcList API. The SilcList is meant for lists that has a structure
6644 already defined as a list. It is not suitable to add just some
6645 context to the list (in TRQ, the context is the list actually).
6647 So, I defined SilcDList that can be used for the purpose where
6648 predefined list structure does not exit. This can be used as
6649 such list. Now some context just can be added to the SilcDList.
6650 Currently this list is not used in the SILC just yet, though there
6651 are a lot places where this can replace dynamically allocated
6652 tables and I will fix these places, later, to use SilcDList.
6653 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6654 and use TRQ internally).
6656 Also fixed some annoying warning messages that the original TRQ
6657 code generated. Also minor changes to TRQ's Makefile.in.
6659 * Added support for querying by Client ID to both WHOIS and
6660 IDENTIFY commands into server, as required by the protocol.
6662 * Removed method function pointers from SilcBuffer structure. They
6663 weren't used to anything and just increased the context size for
6664 no good reason. This change also made silc_buffer_alloc and
6665 silc_buffer_free functions inline functions.
6667 * Disabled command flooding detection support until it's fixed so
6668 that it accepts commands in but does not execute them more than once
6671 * Added silc_net_localhost(), to return local hostname, into
6672 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6673 that must be initialized before calling silc_client_init.
6675 * Added new function: silc_server_send_notify_on_channels to send
6676 notify messages to all channels client has joined. It is assured
6677 that the message is sent only once per client.
6679 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6680 lib/silcutil/silcutil.[ch] as silc_format function. The new
6681 function is generic and is used by server as well, not only by
6682 the logging routines.
6684 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6685 the provided version string was not acceptable. Added new function:
6686 silc_ske_check_version into lib/silcske/silcske.h. The function
6687 must be implemented by the application (client or server) and it
6688 does not reside in the SKE library. The function checks the version
6689 string remote end sent.
6691 * Added back pointers (to opaque context and to SilcSocketConnection)
6692 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6694 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6695 duplicate packet context structure.
6697 * Changed `notify' client operation to send same arguments as client
6698 receives from server except for ID's. ID's are mapped to correct
6699 ID entry and that is returned. Also, if channel entry is not sent
6700 by server but the notify is for channel the channel entry is sent
6701 to application (otherwise application doesn't know that it is for
6702 channel (library gets it from packet's Destination ID)).
6704 * Added silc_client_remove_from_channels into client library to
6705 remove a client from all channels it has joined to. Used when
6706 received SIGNOFF notify from server. Added also new function
6707 silc_client_replace_from_channels to replace old ID entry with
6708 new ID entry on all channels. Used when received NICK_CHANGE
6711 * Fixed ID Cache list handling in silc_idlist_get_client in
6712 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6713 to get (or query) client by ID.
6715 * Updated TODO list.
6717 * Added connection authentication status message defined by the
6718 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6719 support for these into the code in client and server side.
6721 * Added generic function silc_client_send_command to send any command
6722 with variable argument list. Application should use this function
6723 to send commands if the command functions provided by the library
6724 does not suite for the application's user interface needs.
6726 * Added new `failure' client operation. Application is notified about
6727 received failure packet if client is executing a protocol. In this
6728 case the protocol's execution has failed.
6730 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6731 is required by the protocol.
6733 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6734 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6737 * Added status flag to SilcSKE object to indicate realtime status
6738 of the SKE protocol.
6740 * Application receives now exactly same command reply arguments as
6741 the library receives from server. However, if ID is received the
6742 corresponding ID entry is returned to the application (eg. Client
6743 ID is mapped to correct SilcClientEntry entry and that is returned).
6744 Changed command_reply client operation due to this change.
6746 * Changed all ID's in commands and in command replys as ID Payloads.
6747 Change affected both client and server side codes.
6749 All ID's sent in SILC network (with execption of ID's in SILC
6750 Packet header) are sent in ID Payload to support variable length
6753 * Server now notifies nick changes and notifies all clients on
6754 the channels about the new nickname (about the new Client ID,
6757 * Implemented CMODE command to change channel modes. Supports all
6758 channel modes defined by the protocol specs except ban and invite
6759 lists. (Also, private channel key mode is supported but support for
6760 setting private channel key in client is missing, thus, this mode
6761 has no effect on client side (except that server requires that the
6762 client uses private channel key and normal channel traffic does not
6765 Also, invite mode works per se, but INVITE command does not work
6766 yet correctly, so you can set channel as invite only channel but
6767 inviting clients to the channel does not work (it is yet to be
6768 thought what's the best way to do it).
6770 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6771 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6772 Implemented CUMODE command to change user's mode on the channel.
6773 Supports all modes defined by the protocol specs.
6775 * Added NAMES command reply to return users modes on the channel.
6777 * Removed unnecessary and slow ciphers from lib/silccrypt.
6779 * Set SO_KEEPALIVE option to connection sockets by default.
6781 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6783 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6784 redefined the Notify Payload into protocol specs.
6786 * Added silc_id_payload_parse_id to get ID directly from raw
6789 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6791 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6792 accept searching by Client ID as well.
6794 * Added support for LEAVE and SIGNOFF notify types in client library.
6796 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6797 to parse ID Payload from raw data.
6799 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6801 * Added flags parameter into silc_ske_assemble_security_properties
6802 function in lib/silcske/silcske.[ch].
6804 * Changed notify client operation to fit better for notify messages
6805 sent by server. The notify payload received from server is now
6806 passed to the application (after parsing it to SilcNotifyPayload).
6807 It is application's responsibility to retrieve the arguments
6808 from the payload and show the message the way it wants. The message
6809 sent by server is implementation specific.
6811 * Changed public keys to comply with the protocol specification.
6812 Old public keys are not supported anymore and are not compatible.
6814 * Removed nickname from Channel Payload as the latest draft removed
6815 it. The client must resolve the nickname from the NAMES command
6816 reply received when it joined the channel.
6818 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6820 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6822 * Fixed some errors in protocol specification drafts.
6824 * Created lib/silccore/silcnotify.c to implement Notify Payload
6825 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6826 generic payloads described by protocol specifications. The file
6827 includes implementations for ID Payload and Argument Payload.
6829 * Changed Command Payload implementation to use the new Argument
6830 Payload. Changed command_xxxx_payload to command_payload_xxxx
6831 to comply with SILC coding conventions.
6833 * Added suppport for Argument Payload handling in Notify Payload
6834 implementation as protocol requires it. Added the new support
6835 into server and client lib as well.
6837 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6839 * Added support for multiple nicknames on same channel. [n] is
6840 added locally to the nickname if there are more than one same
6841 nicknames on the channel.
6843 * Server now sends all nicknames that matched WHOIS request.
6844 Client also shows the list received from server.
6846 * Added TOPIC command to client side. User can now set and show
6847 current topic on channel.
6849 * Added MOTD command to client and server. Also, server sends the
6850 motd when client connects to the server.
6852 * Changed version strings to comply ISO 8601.
6854 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6856 * Fixed protocol error handling in client library. It should now
6857 cope even if the SKE fails for some reason.
6859 * Made new protocol specification drafts for submitting to IETF.
6861 * Implemented TOPIC command to server in silcd/command.c.
6863 * Added two new notify types into lib/silccore/silcnotify.h:
6864 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6865 notify nickname change and topic setting/change on a channel.
6867 * API change of command_reply operation in client library. The
6868 application gets now the status type received from server as well.
6870 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6872 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6874 * Cras fixed and optimized the packet handling even further and
6875 it should work now. Minor change to the prototype of function
6876 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6878 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6880 * Added new function into lib/silcutil/silcschedule.[ch]:
6881 silc_schedule_with_fd to select() a specified fd. The function
6882 returns after timeout expires or data arrives or goes. The
6883 function is used by packet routines to wait that all data is
6884 received from network.
6886 * Fixed data reading from network in lib/silccore/silcpacket.c.
6887 The code now assures that all data is read from the fd and then
6888 continues packet processing. This was a bug fix since the code
6889 used to drop some data in some circumstances.
6891 * Added new function into lib/silcclient/client.[ch]:
6892 silc_client_start_key_exchange to start key exchange after
6893 connection has been established to server. The code internally
6894 now uses this funtion but its main purpose was to provide it
6895 for applications that perform their own connecting. After
6896 application has created a connection it merely calls this
6897 function to start the key exchange between client and server.
6898 The library takes care of everything else after that.
6900 Updated also lib/silcclient/README to explain the usage of
6903 * Do not send to application information that connection has
6904 been established. Application gets notified it by connect
6907 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6909 * Applied cras's patch to add silc_schedule_one function. The
6910 function runs scheduler once and returns.
6912 * Fixed the scheduler after cras messed it up. The timeout
6913 handling works now as it's supposed to work.
6915 * Added into lib/silccore/ silcnotify.h to include notify
6916 message types support. Changed silc_server_send_notify*
6917 functions, in server.[ch], to support those new notify types.
6918 Added the support for the notify types into client library,
6919 as well. Added new notify client operation into ops.h in
6922 * Changed silc_server_packet_send_to_channel to send normal
6923 packets instead of just channel message packets. The function
6924 is now used to send the notify packets to channels. It is not
6925 used to send channel message packets anymore, as server never
6928 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6929 va_arg()s as it seems to require it nowadays. I guess, if SILC
6930 is compiled with older va_arg() the new code should work anyway.
6932 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6934 * Splitted core library. Core library (lib/silccore) includes
6935 now only SILC protocol specific core (and common) components.
6936 Created new utility library (lib/silcutil) that includes more
6937 generic purpose stuff. The stuff for util library was taken
6938 from the old core library. This was minor and easy split.
6940 * Created SILC Client Library (lib/silcclient) that includes
6941 implementation of the SILC client without user interface. This
6942 was major move from silc/ directory. The code has been changed
6943 so that it is transparent towards the user interface. The
6944 silc/ directory includes now the same user interface as before
6945 and it uses the new client library. Read lib/silcclient/README.
6946 Basicly, the client library performs everything else related
6947 to SILC except user interface handling. Also, configuration
6948 files are considered to be part of user interface and library
6949 does not handle them.
6951 This change also changed a lot of structures, function naming etc.
6952 Most important change was that SilcClientWindow object was
6953 renamed to SilcClientConnection in the client library. Created
6954 also new file lib/silcclient/ops.h. Also added new files
6955 silc/local_command.[ch] and silc/client_ops.[ch].
6957 All these changes were made to make it easier for user interface
6958 designers to create what ever user interface for the SILC client
6961 It is also expected that the server will be moved to lib
6962 directory as well and SILC Server Library will be created;
6963 sometimes in the future.
6965 * Removed Local commands from lib/silccore/silccommand.h as
6966 they are application specific and new client library does not
6967 handle any of those anymore.
6969 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6970 old client implementation in silc/.
6972 * Added support for callback functions in SILC_LOG_* macros.
6973 Application can now set its own callbacks that will be called
6974 instead of using the default functions that will always print
6975 the debug messages to stderr (or stdout). Also, debugging can
6976 now be disabled by setting silc_debug to FALSE and re-enabled by
6977 setting it to TRUE. Note, that logging will still work even
6978 if debugging is disabled.
6980 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6981 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6982 silc_log_reset_debug_callbacks.
6984 * To enable debugging in silc client one must give now -d
6985 option on command line.
6987 * Changed silc_schedule_init to automatically allocate task queues
6988 if they are not allocated before calling it.
6990 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6992 * Added GMP 3.1 into math library.
6994 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6996 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6997 a channel in SILC network. The packet is used by servers and
6998 routers to notify other routers that user has left a channel.
6999 This little feature was missing until now. Added the feature
7000 to protocol specification as well.
7002 Added functions: silc_server_send_remove_channel_user and
7003 silc_server_remove_channel_user into server.[ch].
7005 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7006 lib/silccore/silcpacket.h. However, they are not implemented
7009 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7011 * Fixed joining to a channel and sending channel messages
7012 between server and router. The channel message sending should
7013 now work inside a cell.
7015 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7017 * Fixed the private message sending between server and router.
7018 The private message sending should now work inside a cell.
7020 * Added silc_server_replace_id into server.[ch] to replace
7021 existing ID in the SILC network.
7023 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7024 and silc_idlist_replace_server_id into idlist.[ch] in server.
7026 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7028 * Fixed the server to server connections. Server can again now
7029 connect to router. Router to router connections probably does
7032 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7034 * Added dynamic protocol registering support. Now protocols can
7035 registered and unregistered on the fly. Patch by cras.
7037 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7039 * Added lib/contrib directory to hold routines that some platforms
7040 don't have but are needed by SILC.
7042 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7043 into lin/contrib to provide getopt() and getopt_long() for
7044 those who don't have it.
7046 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7048 * Added AWAY command to client. When away message is set and
7049 client receives a private message packet the client automatically
7050 replies to the sender with the away message.
7052 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7053 bug seemed to be the cause of recent problems when compiling
7056 * Added version detection support to SKE protocol specification
7057 and added the new changes to the SKE implementation as well.
7058 There were other minor changes in the SKE protocol as well.
7060 Many changes in lib/silcske/silcske.[ch] and in
7061 lib/silcske/payload.[ch].
7063 * Added ^U functionality, clear input line. Patch from cras.
7065 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7067 * Mainly small bugfixes on core library. Fixed some debugging
7068 logging and buffer overflow in silclog.c.
7070 * Updated config.sub and config.guess on the distribution tree.
7072 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7074 * Added command lagging support in server. Client may execute
7075 commands now only once in two seconds.
7077 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7079 * Optimized packet reception. MAC computation and checking is now
7080 also more optimized. A lot previously duplicated code is now
7081 used as generic by both client and server.
7083 * Fixed key pair generation in clientutil.c
7085 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7087 * Added into lib/silccore/silcbufutil.[ch] new function;
7088 silc_buffer_realloc.
7090 * Moved generic packet sending/encryption functions to
7091 lib/silccore/silcpacket.[ch] from client and server. Some
7092 rewriting of the functions.
7094 * Moved all generic packet reception/decryption functions to
7095 lib/silccore/silcpacket.[ch] from client and server. The
7096 packet processing is now much cleaner in both client and server.
7097 These were major changes in both client and server.
7099 * Created many common functions in server to do packet sending.
7100 Previously code were duplicated a lot, this has been removed
7103 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7105 * Rewrote major parts of the ID cache system. Don't know
7106 whether it is better now or not but at least the API is more
7109 * Major rewrite on ID cache stuff on client because of the ID
7110 cache API changes. Added idlist.c to client.
7112 * Also major rewrite on ID cache stuff on server as well.
7113 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7114 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7115 in hand, instead they are all put into the ID cache system now.
7116 All server_idlist_* routines uses ID cache now instead of
7117 traversing its own lists (those lists does not exist anymore).
7118 SilcIDList though still exists. Also, SilcXXXEntry's are
7121 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7123 * Finally made the SKE implementation compliant to the protocol
7124 specification. All mp integers are now binary encoded as
7125 opposed being HEX encoded.
7127 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7130 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7131 functions: silc_[encode/decode]_pem. Also added function
7132 silc_encode_pem_file to PEM encode with newlines ('\n') for
7135 * SILC public keys are now encoded either PEM or binary. Same
7136 option is for private keys as well. By default private keys
7137 are binary encoded and public keys PEM encoded. Silly HEX
7138 encoding were removed.
7140 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7141 function to create fingerprints.
7143 * Fixed a bug in SHA1; does not change the original data anymore.
7145 * Partly implemented INFO command on client and server side.
7146 Fixed CLEAR command. Changes to SERVER command; show current
7147 server(s) when giving command without arguments. Added
7148 VERSION command to client.
7150 * Added check to server that unregistered connections cannot
7151 execute commands (unless it is specificly allowed).
7153 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7155 * Fixed screen refresh.
7157 * Fixed channel joining bug from client. On some circumstances
7158 client tried to join to a channel it had already joined.
7160 * Added public key verification process into client's protocol.c.
7161 The client now verifies the public key from user and saves
7162 it into ~./silc/serverkeys/ directory.
7164 Added into: clientutil.[ch]: silc_client_verify_server_key.
7166 * Changed SKE protocol's silc_ske_initiator_finish function
7167 to accept callback function that verifies the received public
7168 key. Removed old silc_ske_verify_public_key function.
7170 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7172 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7173 silc_pkcs_private_key[_data]_set.
7175 * Made the password and public authentication more cleaner in
7176 server's protocol.c.
7178 * Removed historic and obsolete protocol `channel_auth' from
7179 both client and server.
7181 * Removed wrong way of sending command status messages from
7182 server to client in server's command.c. The old way violated
7183 protocol specification.
7185 Changes to silccore/silccommand.[ch]: removed
7186 silc_command_encode_status_payload -> not needed anymore,
7187 changed silc_command_encode_payload_va to accept extra
7188 argument on variable argument list. The argument type must
7189 now be provided to the function. Also, added new function:
7190 silc_command_encode_reply_payload_va which is same as
7191 normal command_encode_payload_va except command status type
7192 is provided as extra argument.
7194 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7196 * Added ~./silc directory handling. The directory includes the
7197 public and private keys for the client.
7199 Added silc_client_check_silc_dir, silc_client_create_identifier
7200 and silc_client_load_keys.
7202 * Implemented SILC protocol compliant public key. Added public
7203 and private key saving to and loading from files.
7205 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7206 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7207 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7208 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7209 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7211 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7212 silc_pkcs_load_[public/private]_key.
7214 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7216 * Added silc_server_get_route (route.[ch]) to get connection
7217 data for the fastest route for given ID.
7219 * Implemented INVITE command on client and server. The command
7220 were re-defined in the SILC Protocol Specification and the
7221 implementation now complies with the specification.
7223 * Implemented PING command on client and server.
7225 * Implemented NAMES command on client and server. The server side
7226 supports currently only normal server not router server yet.
7227 Some changes to NAMES definition in SILC protocol specification.
7229 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7231 * Implemented LEAVE command on client and server.
7233 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7234 again. This change was made to the protocol as well. Server
7235 should not violate the protocol specification anymore.
7237 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7239 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7240 was tested. SOCKS4 was not but should work anyway.
