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

40 the SKE interface a bit.
42 * Fixed padding problem in PKCS#1. The padding was not actually
43 random since the random number generator was used incorrectly.
44 This security bug affects only when encrypting with PKCS#1, and
45 it is not currently used at all in SILC. SILC only use signing
46 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
48 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

114 * Added new configuration options and blocks:
115 keepalive_secs, reconnect_count, reconnect_interval,
116 reconnect_interval_max, reconnect_keep_trying and
117 require_reverser_lookup. Added ConnectionParam block, and
118 implemented the connection parameters when connecting as
119 initiator and when accepting connections as responder.
121 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
122 whether given configuration value has been given already.
124 Affected files silcd/serverconfig.[c], server.[c].
126 * Splitted the doc/example_silcd.conf.in. Separated the crypto
127 algorithm parts and created new file silcalgs.conf, that
128 is now included from the example_silcd.conf.in.
130 * Optimized the silc_server_connect_to_router_second to take
131 the connection configuration object from the SilcServerConnection
132 object instead of finding it during the connecting phase.
133 Added the configuration object to SilcServerConnection struct.
134 Affected files silcd/server_internal.h, server.c.

150 * Unified the serverconfig.[ch]'s helper function interface.
151 Affected file silcd/serverconfig.[ch].
153 * Removed doc/example_silc.conf.in since it is redundant.
154 The make install will now install irssi/silc.conf file.
156 * Added new Passphrase and Publickey authentication methods to
157 config file, allowing both public key and passphrase based
158 authentication to be set at the same time.
160 Added `prefer_passphrase_auth' setting in config file which
161 can be used to set to prefer passwd auth if both passwd and
162 public key is set. If not set, public key is preferred.
163 This has effect only when being initiator (responder will try
166 Added support for authentication with passphrase and public key
167 at the same time. The passphrase is tried first always since
168 it is faster to check.
170 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
172 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

214 hash algorithm. Affected file lib/silccrypt/silcrng.c.
216 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
218 * Fixed the file transfer's key agreement payload to include
219 zero port also if the hostname is NULL because it could not
222 Call file transfer monitor callback now also if error occurs
223 during key agreement protocol.
225 Changed the silc_client_file_send interface to return the
226 SilcClientFileError instead of session id. The session ID
227 is returned into pointer provided as argument.
229 Check that the file exists locally before sending the
230 file transfer request at all.
232 Affected file lib/silcclient/client_ftp.c, silcapi.h.

244 file lib/silcutil/silclog.c.
246 * Fixed the channel message payload decryption in the function
247 silc_channel_message_payload_decrypt to not modify the original
248 buffer before it is verified that the message decrypted
249 correctly. Otherwise, next time it is called with correct
250 channel key it won't encrypt since the payload is corrupted.
251 Affected file lib/silccore/silcchannel.c.
253 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

281 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
283 * Fixed private message handling. It used some old code that
284 caused the client to crash. Affecte file is
285 lib/silcclient/client_prvmsg.c.
287 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
289 * Added function silc_client_add_channel,
290 silc_client_replace_channel_id, and removed functions
291 silc_client_new_channel_id and silc_idlist_get_channel_by_id
294 * Added cross reference of the joined channels to the
295 SilcClientEntry, and changed the SilcChannelEntry's
296 users list to SilcHashTable. The affected files are
297 lib/silcclient/idlist.[ch].
299 * Fixed a bug in hash table tarversing. While the hash table
300 is traversed with SilcHashTableList the table must not be
301 rehashed. It is now guaranteed that auto rehashable tables
302 are not rehashed while tarversing the list. Also defined that
303 silc_hash_table_rehash must not be called while tarversing
304 the table. Added function silc_hash_table_list_reset that must
305 be called after the tarversing is over. The affected files are
306 lib/silcutil/silchashtable.[ch].
308 * Changed all hash table traversing to call the new
309 silc_hash_table_list_reset in server and in client library.
311 * Added function silc_client_on_channel to return the
312 SilcChannelUser entry if the specified client entry is joined
313 on the specified channel. This is exported to application as
314 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
316 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
318 * Fixed founder regaining problem with JOIN command on normal
319 server. The notify for mode change must be sent always and
320 not only if !cmd->pending. Affected file silcd/command.c.
322 * Fixed the WHOWAS command's reply sending to support the
323 lists correctly. Affected file silcd/command.c.
325 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
327 * When sending JOIN command to router for processing the
328 sender's old command identifier was not saved back to the
329 sender's command context, fixed now. The affected file is
332 * Create the key in JOIN command of the router did not return
333 the channel key, added check for this. Affected file is
336 * Fixed a channel ID update bug in JOIN command reply. Do
337 not directly upgrade the ID but call the function
338 silc_idlist_replace_channel_id if the ID was changed.
339 Affected file silcd/command_reply.c.
341 * Fixed memory leaks from command calling if it would fail.
342 Affected file silcd/command.c.

354 * Removed TRQ from lib/trq, not needed anymore.
356 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
357 with server connections. Later this will be configurable
358 in config file after new config file is done. Affected file
361 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
363 * Fixed a crash in server related to channel announcements.
364 Affected file silcd/server.c.
366 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
368 * Fixed memory leaks in silc_server_create_new_channel*
369 functions. Affected file silcd/server.c.
371 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
372 which ID was changed. This way the router will send the
373 user list for the channel again, and server won't be in
374 desync in some rare circumstances. Affected file is
375 silcd/packet_receive.c.
377 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

405 * Added server & router operator statistics updating. Affected
406 file silcd/packet_receive.c and silcd/command.c.
408 * Fixed the SERVER_SIGNOFF notify handling on normal server
409 not to save the history information for clients. Same was
410 fixed earlier in remove_clients_by_server function, but not
411 here. Affected file silcd/packet_receive.c.
413 * Raised the default connection-retry count from 4 to 7 in
414 server. Affected file silcd/server.h.
416 * Cancel any possible reconnect timeouts when we start the
417 key exchange. Affected file silcd/server.c.

424 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
426 * Fixed the NICK command to always give the unformatted
427 nickname to the one giving the NICK command. If unformatted
428 nickname is cached already it will be formatted and the
429 local entry will always get the unformatted nickname.
430 Affected file lib/silcclient/idlist.c.
432 * Fixed some double frees from client library commands.
433 Affected file is lib/silcclient/command.c.
435 * Fixed CUMODE command in server to assure that no one can
436 change founder's mode than the founder itself, there was a
437 little bug. Affected file silcd/command.c.
439 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
441 * Removed the SilcClientCommandDestructor from the client
442 libary, it is not needed anymore. Affected files are
443 lib/silcclient/silcapi.h, command[_reply].[ch],
444 client_notify, idlist.c.
446 * Fixed GETKEY command to first resolve client, and then
447 resolve the server only if the client was not found, instead
448 of resolving both at the same time. Affected file is
449 lib/silcclient/command.c.
451 * Added silc_client_start_key_exchange_cb and lookup the
452 remote hostname and IP address before starting the key
453 exchange with server. The affected file is
454 lib/silcclient/client.c.
456 * The server's public key is now saved using the IP address
457 of the server and not the servername for the filename.
458 The hostname public key filename is checked as an fall back
459 method if the IP address based filename is not found.
461 Fixed the GETKEY command to save the fetched server key
464 Print the remote server's hostname now when new key is
465 received during connection process. Affected file is
466 irssi/src/silc/core/client_ops.c.
468 * Return always our own public key to the client if it asks
469 for it with GETKEY command. Affected file silcd/command.c.
471 * Removed the use_auto_addr variable from default config
472 file since it was in wrong section. Affected file is
475 * Fixed TOPIC_CHANGE notification to not route it when it
476 was sent using silc_server_send_notify_to_channel function.
477 Affected file silcd/command.c.
479 * Fixed silc_server_send_notify_kicked to send the kicker's
480 Client ID also, it was missing. Affected files are
481 silcd/command.c, silcd/packet_send.[ch].
483 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
485 * Do not save client history information in SERVER_SIGNOFF.
486 Fixes the bug in normal server that it does not detect
487 the client becoming valid after the server becomes back
488 online. Affected file silcd/server_util.c.
490 * Added `sock_error' field into the SilcSocketConnection
491 context. When error occurs during socket operation (read
492 or write) the error is saved. Added also new function
493 silc_socket_get_error to return human readable socket error
494 message. Affected files are lib/silcutil/silcsockconn.[ch],
495 lib/silcutil/unix/silcunixsockconn.c, and
496 lib/silcutil/win32/silcwin32sockconn.c.
498 * The server now prints the socket error message in the
499 signoff for client. Affected file silcd/server.c.
501 * Fixed the `created' channel information sending from router
502 to server in JOIN command. Checks now whether the channel
503 really was created or not and set it according that.
505 Fixed the JOIN command to use the client entry's current
506 ID during the joining procedure instead of the one it sent
507 in the command (it is checked though), since it can change
508 between the packet processing and command processing, and
509 would just case unnecessary pain in the client end. Affected
510 file silcd/command.c.
512 * Fixed a channel key payload sending to use correct channel
513 ID when the server was forced to change the channel's ID by
514 router. Router sent the key payload with the old Channel ID.
515 Affected file silcd/packet_receive.c.
517 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
519 * Call silc_server_save_channel_key only if the key payload
520 was provided in the JOIN command's command reply. Affected
521 file silcd/command_reply.c.
523 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
525 * Fixed silc_mp_sizeinbase to return the value correctly with
526 MPI. Affected file lib/silcmath/mp_mpi.c.
528 * Fixed the stop_server signal to correctly stop the scheduler
529 and gracefully stop the server when SIGTERM or SIGINT signals
530 are received. Affected file silcd/silcd.c.
532 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
534 * Simple handling of TERM and HUP signals. Also added some log
535 flushing call around. Affected file is
538 * Fixed small bugs in silclog.c. Now buffering output will take
539 effect after 10 seconds since startup: This will ensure that
540 no important startup messages are lost. Also output redirection
541 will preserve original format ([Date] [Type] message).
542 Affected file is lib/silcutil/silclog.c.
544 * Added two options to the config file, in the logging section:
545 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
546 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
548 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
550 * Do not print the warning about log files not being initialized
551 more than once to avoid excess logging. Affected file is
552 lib/silcutil/silclog.c.
554 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
555 the SIM copying in make install in Makefile.am.pre.
557 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
559 * Rewritten silclog APIs. Globally interesting changes follows:
560 silc_log_set_files() changed to silc_log_set_file().
561 silc_log_set_callbacks() changed to silc_log_set_callback().
562 ROBOdoc documented silclog header file.
563 SilcLogCb now returns bool to wether inihibit the default
564 handler or not (to keep the old behaviour return always TRUE).
565 The new APIs should also fix the problem of the
566 silcd_error.log file that was written in the current directory.
569 Log files streams will remain opened after silc_log_set_file()
570 call, means less CPU usage notably on high traffic servers.
571 File streams are now full buffered, and flushed to the disk
572 every 5 minutes, lesses HD activity and CPU usage.
573 Messages can be redirected, allowing admins to configure
574 one single logfile for all server messages.
575 the silc_log_quick global variable to activate fast-logging.
576 Affected files lib/silcutil/silclog.[ch]
578 * Changed some code to conform new silclog APIs. Affected
579 files are doc/example_silcd.conf.in, silcd/server.c
580 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
583 * Fixed a memory leak that could occur in some situations.
584 Affected file silcd/serverconfig.c.
586 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
588 * Added the silc_client_del_client to remove the client from
589 all channels as well. Affected file lib/silcclient/idlist.c.
591 * Fixed the client library to correctly remove the client
592 from all channels when the client entry is being destroyed.
593 Affected file lib/silcclient/client_notify.c, command.c.
595 * Added auto-nicking support to the client library. If the
596 applicatio now sets client->nickname it will be sent to the
597 server after connecting by the library. This way for example
598 SILCNICK (or IRCNICK) environment variables will have effect
599 and always change the nickname automatically to whatever
600 it is wanted. Affected file lib/silcclient/client.[ch].
602 * Renamed silc_server_command_bad_chars to the
603 silc_server_name_bad_chars and moved it to the
604 silcd/server_util.[ch]. Added also new function
605 silc_server_name_modify_bad to return nickname that
606 includes bad characters as new nickname without those
607 bad characters. This check and modify is now used in
608 silc_server_new_client when the username is initially set
609 as nickname, so it must be checked to be valid nickname.
610 Affected file silcd/packet_receive.c.
612 * The nickname length is now taken from the packet for real
613 and not trusted to strlen() since it clearly can return
614 wrong length for nickname including bad characters. This
615 also applies to channel names. Affected file silcd/command.c.
617 * Removed the lib/silcsilm/modules directory. Modules are now
618 compiled into the lib/silcsim. Fixed the copying of the
619 modules to follow symbolic links in Makefile.am.pre.
621 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
623 * Fixed silc_string_regexify list creation. Fixes bugs with
624 BAN and INVITE commands in server. The affected file is
625 lib/silcutil/unix/silcunixutil.c.
627 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
629 * Removed the command destructor entirely from the server's
630 command and command reply routines. It is not needed, and
631 its usage was buggy and caused crashes. Affected files are
632 silcd/command[_reply].[ch].
634 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
636 * Cancel protocol and NULL sock->protocol if timeout
637 occurred during protocol. Affected file silcd/server.c.
639 * Cancel protocol timeouts always before calling the final
640 callback, to assure that after final callback is called
641 no other state will be called for the protocol anymore.
642 Affected file silcd/protocol.c.
644 * Print error log if incoming connection configuration could
645 not be found. Affected file silcd/server.c.
647 * Fixed JOIN command to correctly save the founder mode
648 to the client on normal SILC server, when the channel
649 was created by the router. Affected file silcd/command.c.
651 * Fixed LIST command (hopefully) to send correct reply
652 packets. Affected file silcd/command.c.
654 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
656 * The silc_packet_receive_process now returns FALSE if the
657 read data was invalid packet, and TRUE if it was ok.
659 The server now checks that if unauthenticated connection
660 sends data and its processing fails the server will close
661 the connection since it could be a malicious flooder.
663 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
665 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
667 * Make sure the warning about error opening a log file is
668 printed only once and not everytime it fails (produces
669 too much useless log). Affected file lib/silcutil/silclog.c.
671 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
673 * Made the silc_server_daemonise() function more readable.
674 Affected file silcd/server.c.
676 * Pid file is now optional, the user may comment it out from
677 the config file. Removed define SILC_SERVER_PID_FILE, we
678 don't need a default any longer. Affected file
679 configure.in.pre, lib/Makefile.am.pre.
681 * Make some use of the pid file. The server now dies at startup
682 if it detects a valid pid file on his path. The server would
683 die anyway in this circumstance, because of the bind() failure.
684 Affected file silcd/silcd.c.
686 * No longer compiling lib/dotconf.
688 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
690 * Fixed JOIN command parsing not to crash. Affected file
691 lib/silcclient/command.c.
693 * Fied the NICK_CHANGE notify to add the new client entry
694 even it is resolved. This removes an <[unknown]> nick
695 thingy bug in the client. Affected file is
696 lib/silcclient/client_notify.c.
698 * Do not try to allocate 0 bytes (efence does not like it)
699 in lib/silccore/silccomand.c when encoding payload.
701 * Do not take IRCNICK as nickname in Irssi SILC client since
702 it is not possible to set nickname before hand connecting
703 the server (TODO has an entry about adding auto-nicking
706 * Changed the silc_server_command_pending to check whether
707 there already exists an pending entry with the specified
708 command, command identifier and pending callback. This is
709 to fix IDENTIFY and WHOIS related crashes that may register
710 multiple pending commands with same identifier. Affected
711 file silcd/command.c.
713 * Fixed the server to reconnect to the router even if it
714 was already reconnecting and EOF was received. This to
715 fix a possibility that the server wouldn't ever try to
716 auto-reconnect to the router. Affected file silcd/server.c.
718 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
720 * Fixed the server's password authentication to use the
721 length of the locally saved password, and not the one
722 sent in the packet. Affected file silcd/protocol.c.
724 * Fixed same password authentication problem in the
725 Authentication Payload handling routines in
726 lib/silccore/silcauth.c.
728 * Yet another password authentication problem fixed with
729 channel password handling in silcd/command.c.
731 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
733 * If first character of string in silc_parse_userfqdn is '@'
734 then do not parse it. Affected file is
735 lib/silcutil/silcutil.c.
737 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
739 * Fixed minor bug in IDENTIFY command reply sending, which
740 caused various weird problems during JOIN when it was
741 resolving names for users. Affected file silcd/command.c.
743 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
745 * Fixed the IDENTIFY command reply sending to chech better valid
746 clients. It was possible to send incomplete list of replies.
747 Affected file silcd/command.c.
749 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
751 * Added silc_client_command[s]_[un]register functions now to
752 dynamically register the commands in client library. Removed
753 the static table of commands. This allows the client library
754 to call commands without causing the application to know about
755 what commands library has called.
757 Removed the INFO command reply kludge to detect when the command
758 was called by library. Now library use its own command reply
759 function for INFO command.
761 Added function silc_client_command_call to call a command.
762 Application can use it to call command, not access the structure
765 Now all commands that are sent by the client library (not
766 explicitly sent by application) use own command reply functions.
768 Affected files around lib/silcclient/ and in
769 irssi/src/silc/core/.
771 * Fixed the WHOIS command reply sending to chech better valid
772 clients. It was possible to send incomplete list of replies.
774 Fixed the WHOIS and IDENTIFY to send the request to router
775 if normal server did not do it and did not find any results.
777 Affected file silcd/command.c.
779 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
781 * Moved the internal data from SilcClient context into its
782 own file, not accesible to application. Affected files
783 lib/silcclient/client.h and lib/silcclient/client_internal.h,
784 and other files in client library.
786 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
788 * Added doc/examples installation target in Makefile.am.pre.
791 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
793 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
794 commands the found client entry will be removed from the
795 cache, after notifying application about the error. Affected
796 file lib/silcclient/command_reply.c.
798 * Changed the /MSG to check for exact nickname user gave, and
799 not let `nick' match `nick@host' if it is only one found. Now,
800 user must type the exact nickname (like nick@host2) even if
801 there are no more than one same nicks found. This is to avoid
802 a possibility of sending nickname to wrong nickname since
803 `nick' could match `nick@host'. Affected file is
804 irssi/src/core/silc-servers.c.
806 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
808 * Do not print "you are now server operator" or similar when
809 giving /away command. Affected files are
810 irssi/src/silc/core/client_ops.c, silc-servers.h.
812 * Made the silc_server_command_pending_error_check to send
813 the same command reply payload it received back to the
814 original sender of the command. This way all arguments
815 that was received by the server will be received by the
816 client too. Affected file silcd/command.c.
818 * Added the silc_idcache_add to return the created cache entry
819 to a pointer. Affected file lib/silccore/silcidcache.[ch].
821 * Add global clients to expire if they are not on any channel.
822 This is because normal server will never know if they signoff
823 if they are not on any channel. The cache expiry will take
824 case of these entries. This is done by normal servers only.
825 The affected files are silcd/command_reply.c,
826 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
828 * If server receives invalid ID notification for WHOIS or
829 IDENTIFY and the ID exists in the lists, it is removed.
830 Affected file silcd/command_reply.c.
832 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
833 in client then client entry that it matches is searched and
834 the nickname is printed on the screen for user. Affected
835 file irssi/src/silc/core/client_ops.c.
837 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
839 * Use cache entry expire time in the LIST command reply to
840 purge old entries from the cache after the LIST command
841 reply has been received. This way we don't have non-existent
842 entries in the cache for too long. Affected file is
843 silcd/command_reply.c.
845 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
847 * If we are normal server, and we've not resolved client info
848 in WHOIS or IDENTIFY from router, and it is global client,
849 we'll check whether it is on some channel. If it is not
850 then we cannot be sure about its validity and will resolve it
851 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
852 file silcd/command.c.
854 * Search channel by name (if possible) rather than by ID
855 in IDENTIFY command's command reply. Affected file is
856 silcd/command_reply.c.
858 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
860 * Distribute to the channel passphrase in CMODE_CHANGE notify.
861 Updated specs and implemented it. Affected file silcd/command.c,
862 silcd/packet_send.c and silcd/packet_receive.c.
864 * Implemented the <founder auth> payload handling in the JOIN
865 command. If provided all conditions for channel joining
866 except requirement to provide correct passphrase can be
867 overrided by the channel founder. Updated the protocol specs.
868 Affected file silcd/command.c.
870 Added support for founder auth in JOIN command in client
871 library. Fixed the parsing of the JOIN command now to support
872 all options as they should be. The affected file is
873 lib/silcclient/command.c.
875 * Optimized the WHOIS and IDENTIFY commands to send the request
876 to router only if it includes nicknames or other names. If
877 they include only IDs then check the local cache first before
878 routing. Affected file is silcd/command.c.
880 * Added channels topic announcements. Affected file is
881 silcd/packet_receive.c and silcd/server.c.
883 * Fixed the silc_server_send_notify_topic_set to really destine
884 the packet to channel. Affected file silcd/packet_send.c.
886 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
887 library. Affected file lib/silcclient/client_notify.c.
889 * Added UMODE announcements. Affected file silcd/server.c.
891 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
893 * Memory leak fixes in:
895 lib/silcutil/silcsockconn.c
896 lib/silcske/silcske.c
899 lib/silccrypt/silcpkcs.c
900 lib/silccore/silccommand.c
901 lib/silccore/silcidcache.c
906 * ROBOdoc documented the lib/silcske/groups.h file and a
907 bit changed the interface for better.
909 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
911 * Update the client entry context in the ID cache after
912 nick change. Affected file lib/silcclient/command.c.
913 Fixes the CUMODE command when regaining founder privileges,
914 and a little WHOIS problem.
916 * Fixed silc_net_gethostbyname to correctly call the
917 inet_ntop. Affected file lib/silcutil/silcnet.c.
919 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
921 * Added IPv6 support checking to the configure.in.pre, added
922 also --enable-ipv6 option to override the check. Affected
923 file configure.in.pre.
925 * The silc_thread_create now calls the start function
926 directly if threads support is not compiled in. Removes
927 ugly #ifdef's from generic code. Affected files are
928 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
930 * Added silc_net_gethostby[name/addr]_async to asynchronously
931 resolve. Affected files are lib/silcutil/silcnet.[ch].
933 * Added support for rendering IPv6 based server, client and
934 channel IDs. Affected file lib/silcutil/silcutil.c.
936 * Added support for creating IPv6 based server IDs. Affected
937 file is silcd/serverid.c.
939 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
941 * Added silc_net_gethostby[addr/name] into the
942 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
943 routines. Added silc_net_is_ip[4/6]. Affected file is
944 lib/silcutil/unix/silcunixnet.c. All routines that take
945 address as argument now supports both IPv4 and IPv6 addresses.
947 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
949 * Fixed LIST command reply sending in server. Affected file
952 * Server now sends the kicker's client ID in the KICK notify
953 to the kicked client. Affected file silcd/command.c.
955 * The client library now parses the kickers client ID and
956 UI displays it. Affected files lib/silcclient/client_notify.c
957 and irssi/src/silc/core/silc-channels.c, module-formats.c.
959 * Made all payload parsing function prototypes consistent.
960 They all take now const unsigned char * and uint32 pair as
961 the payload data instead of SilcBuffer. Changes all around
962 the source tree. Other unsigned char* -> const unsigned char*
963 changes around the tree as well.
965 * Optimized SFTP client and server packet sending not to
966 allocate new buffer for each packet but to recycle the
967 first allocated buffer. Affected files are
968 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
970 * Optimized the SFTP client to use SilcList instead of
971 SilcDList for requests, because it is faster. Affected file
972 is lib/silcsftp/sftp_client.c.
974 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
975 into lib/silccore/silcid.[ch].
977 Renamed silcpayload.[ch] into silcargument.[ch].
979 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
981 * If client entry is deleted with active key agreement
982 session, abort the session.
984 The silc_client_abort_key_agreement now calls the completion
985 callback with new SILC_KEY_AGREEMENT_ABORTED status.
987 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
990 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
992 * Don't use __restrict in older GCC's. Affected file is
993 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
995 * silc_net_localhost now attempts to reverse lookup the
996 IP/hostname. Affected file lib/silcutil/silcnet.c.
998 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
999 command. It can be used to gain founder privileges at
1000 the same time when joining the channel.
1002 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1003 kicker's client ID as well. Updated protocol specs.
1005 Defined that the server must send SILC_COMMAND_IDENTIFY
1006 command reply with error status to client who sent
1007 private message with invalid client ID.
1009 Updated the protocol specification.
1011 * Added silc_server_send_command_reply to send any
1012 command reply. Affected file silcd/packet_send.[ch].
1014 * Added silc_id_payload_encode_data to encode ID payload
1015 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1017 * The server now send IDENTIFY command reply with error
1018 status if client ID in private message is invalid. Affected
1019 file silcd/packet_receive.c.
1021 * Save the server key file with server's IP address in
1022 the filename instead of hostname. The affected file is
1023 irssi/src/silc/core/client_ops.c.
1025 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1027 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1030 * Added libtool support for compiling shared objects in
1031 lib/silcsim. Affected file configure.in.pre and
1032 lib/silcsim/Makefile.am. Original patch by cras.
1034 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1036 * Pid file configuration, and server's config file fixes
1037 patch by toma. Updated CREDITS file.
1039 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1041 * Fixed silc_client_channel_message to not try to decrypt
1042 the message twice if it resolved the destination client
1043 information. This could cause of dropping one channel
1044 message. Affected file lib/silcclient/client_channel.c.
1046 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1048 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1049 lib/silcclient/client.c. This function is used when the SILC
1050 Client is run under some other scheduler, or event loop or
1051 main loop. On GUI applications, for example this may be
1052 desired to used to run the client under the GUI application's
1053 main loop. Typically the GUI application would register an
1054 idle task that calls this function multiple times in a second
1055 to quickly process the SILC specific data.
1057 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1059 * Fixed silc_server_drop() for dropping the supplementary
1060 groups as well, this could cause a security hole on some
1063 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1065 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1068 * Write PID file after dropping privileges. Added -F option
1069 to run server on foreground. A patch by debolaz.
1070 Affected files silcd/server.c, silcd/silcd.c.
1072 * Fixed MOTD to return the MOTD file server name. Affected
1073 file silcd/command.c.
1075 * Added INFO command reply handling to the Irssi SILC Client.
1076 Affected file irssi/src/silc/core/client_ops.c.
1078 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1080 * Fixed the silc_idcache_list_* routines to really support
1081 the dynamic list. Fixes a crash. Affected file is
1082 lib/silccore/silcidcache.c.
1084 * Fixed the LIST command reply to really call LIST command's
1085 pending callbacks. Affected file silcd/command_reply.c.
1087 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1089 * Update conn->local_entry->nickname after giving NICK
1090 command. Affected file lib/silcclient/command.c.
1092 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1094 * Added the [pid] option to the silcd configuration file
1096 Affected files: serverconfig.[ch] and silcd.c
1098 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1100 * Save fingerprint in WHOIS command reply in server.
1101 Affected file silcd/command_reply.c.
1103 * Fixed NICK commands pending callback registration.
1104 Affected file lib/silcclient/command.c.
1106 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1108 * Use ++server->cmd_ident when sending commands in server,
1109 instead of random number. Affected file silcd/command.c.
1111 * Fixed GETKEY command reply to call actually GETKEY pending
1112 command callbacks. Affected file silcd/command_reply.c.
1114 * A bit stricter check for nicknames. Check for same nickname
1115 in NICK command also. Affected file silcd/command.c.
1117 * Do not call INFO command everytime client ID changes, only
1118 during first connecting. Affected file lib/silcclient/client.c.
1120 * Set the new nickname only after successful command reply for
1121 NICK command is returned by server. Affected file
1122 lib/silcclient/command.c.
1124 * Remove nicknames from nicklist during server_signoff notify.
1125 Should fix /NAMES bit more. The affected file is
1126 irssi/src/silc/core/silc-channels.c.
1128 * Added `fingerprint' field to the SilcIDListData in the
1129 silcd/idlist.h to hold the fingerprint of the client's
1132 Send the fingerprint of the client's public key in WHOIS
1135 Affected files silcd/command.c, and silcd/idlist.[ch].
1137 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1138 create fingerprint from given data.
1140 * Show the fingerprint of the client's public key in WHOIS.
1141 Affected files irssi/src/module-formats.[ch] and
1142 irssi/src/silc/core/client_ops.c.
1144 * Format the multiple same nicknames also during JOIN and
1145 NICK_CHANGE notifys. Affected file is
1146 lib/silcclient/client_notify.c.
1148 * Do not print error on screen for invalid private message
1149 payload since it can come if someone is sending private
1150 messages with wrong key. Affected file
1151 lib/silccore/silcprivate.c.
1153 * Fixed multiple concurrent /PING crash. Affected file
1154 lib/silcclient/command.c.
1156 * Changed the wrong ID encoding. All IP addresses must be
1157 in MSB first order in encoded format. They were encoded
1158 wrong and was in LSB format. Affected files are
1159 silcd/serverid.c, lib/silcutil/silcutil.c.
1161 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1163 * Call the `connect' client operation through the scheduler
1164 in case of error. Affected file lib/silcclient/client.c.
1166 * Call the `failure' client operation even if the error
1167 occurred locally during a protocol. Affected file is
1168 lib/silcclient/protocol.c.
1170 * Added support of sending LIST command to router from normal
1171 server. This way normal server can get list of all channels
1172 in the network too. Fixed the channel list sending in the
1173 server too. Affected files are silcd/command.c, and
1174 silcd/command_reply.[ch].
1176 * Added silc_server_update_channels_by_server and
1177 silc_server_remove_channels_by_server. They are used during
1178 disconnection of primary router and in backup router protocol.
1179 Affected file silcd/server_util.[ch], silcd/server.c and
1180 silcd/server_backup.c.
1182 * Fixed channel adding to global list in IDENTIFY command
1183 reply in server. Affected file silcd/command_reply.c.
1185 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1187 * If the incoming packet type is REKEY or REKEY_DONE process
1188 that packet always synchronously. Fixes yet another MAC
1189 failed error on slow (dialup) connections. Affected file
1190 lib/silcclient/client.c and silcd/server.c.
1192 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1194 * Call check_version SKE callback for initiator too. Affected
1195 file lib/silcske/silcske.c.
1197 * Implemented fix for security hole found in the SKE that was
1198 fixed in the specification few days back; the initiator's
1199 public key is now added to the HASH value computation.
1200 Added backwards support for the old way of doing it too, for
1201 old clients and old servers. Affected file is
1202 lib/silcske/silcske.c.
1204 * Enabled mutual authentication by default in SKE. If initiator
1205 is not providing mutual authentication the responder will
1206 force it. This will provide the proof of posession of the
1207 private key for responder. The affected files are
1208 lib/silcclient/protocol.c and silcd/protocol.c.
1210 * Do not cache anymore the server's public key during SKE.
1211 We do mutual authentication so the proof of posession of
1212 private key is done, and if the server is authenticated in
1213 conn auth protocol with public key we must have the public
1214 key already. Affected file silcd/protocol.c.
1216 * Added new global debug variable: silc_debug_hexdump. If
1217 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1218 file lib/silcutil/silclog.[ch].
1220 * Fixed compilation warning due to char * -> const char *.
1221 Affected files lib/silcutil/silcnet.h, and
1222 lib/silccore/silcauth.[ch].
1224 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1226 * Fixed CMODE command when new channel key was created. If
1227 the creation failed the old key was removed. Next time giving
1228 same command would crash the server since the old key was
1229 freed already. Affected file silcd/command.c.
1231 * Fixed the silc_server_announce_get_channels to not crash
1232 on reconnect. Affected file silcd/server.c.
1234 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1236 * Added silc_log_set_debug_string function to set a regex
1237 string to match for debug output. Only the function names,
1238 or filenames matching the given debug string is actually
1239 printed. This way it is possible to filter out those debug
1240 strings that user is not interested in.
1242 Fixed a bug in silc_string_regexify.
1244 Affected files lib/silcutil/silclog.[ch], and
1245 lib/silcutil/unix/silcunixutil.c.
1247 * Changed the -d options in both server and Irssi SILC client
1248 to take the debug string as argument. Affected files
1249 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1251 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1253 * Added silc_hash_babbleprint to create a Bubble Babble
1254 Encoded fingerprint. The encoding is developed by Antti
1255 Huima (draft-huima-babble-01.txt), and it creates human
1256 readable strings out of binary data. Affected file
1257 lib/silccrypt/silchash.[ch].
1259 * Print the babble print now in addition of fingerprint as well
1260 in Irssi SILC client. Affected files are
1261 irssi/src/fe-common/silc/module-formats.[ch],
1262 irssi/src/fe-common/silc/core/client_ops.c.
1264 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1266 * Fixed a security problem found in SKE. The initiator's
1267 public key too is now added to the HASH hash value creation
1268 which is signed by the responder to create the SIGN value.
1269 This will prevent anyone in the middle to lie to the responder
1270 about the initiator's public key. If this is done now, the
1271 man in the middle will get caught. Updated the protocol
1274 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1276 * Better installation directory handling. Configure module
1277 paths and other paths automatically to example_silc* files
1278 in doc/. A patch by toma.
1280 * Fixed compiler warning from MPI library, and from SILC RNG.
1283 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1284 It can be configured with ./configure. A patch by toma.
1286 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1288 * Find correct make to use in prepare-clean. A patch by
1289 toma. Affected file prepare-clean.
1291 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1293 * Added irssi variables use_auto_addr, auto_bind_ip,
1294 auto_bind_port and auto_public_ip.
1296 * Changed the interface for silc_client_send_key_agreement
1297 in lib/silcclient/silcapi.h
1301 irssi/src/silc/core/silc-core.c
1303 lib/silcclient/silcapi.h
1304 irssi/src/silc/core/silc-channels.c
1305 lib/silcclient/client_keyagr.c
1308 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1310 * Added silc_pkcs_public_key_compare to compare two
1311 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1313 * Check that the client who set the founder mode on the
1314 channel is the same client that is giving the founder
1315 mode to itself. It is done by comparing the saved public
1316 key (it is saved even in the authentication is passphrase).
1317 Affected file silcd/command.c.
1319 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1321 * Do not process packet for disconnected socket connection.
1322 Affected file lib/silccore/silcpacket.c.
1324 * Process the DISCONNECT packet through scheduler in the
1325 client library. Affected file lib/silcclient/client.c.
1327 * Fixed the silc_client_packet_parse to not to increase
1328 the packet sequence number if the conn->sock and the
1329 current socket connection is not same. This can happen
1330 for example during key agreement when the conn includes
1331 multiple socket connections (listeners). Affected file
1332 lib/silcclient/client.c.
1334 * The sender of the file transfer request now provides also
1335 the pointer (listener) for the key exchange protocol. If
1336 the listener cannot be created then it sends empty key
1337 agreement and lets the receiver provide the listener.
1339 Added `local_ip' and `local_port' arguments to the
1340 silc_client_file_send. If they are provided they are used,
1341 if not then it will attempt to find local IP address, if
1342 not found or bind fails then the remote client will provide
1345 Affected files are lib/silcclient/client_ftp.c and
1346 lib/silcclient/silcapi.h.
1348 * Extended the FILE SEND command to support defining the
1349 local IP and port for key exchange listener. They are
1350 optional. Affected file irssi/src/silc/core/silc-servers.c.
1352 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1354 * Defined to WHOIS command reply the sending of fingerprint
1355 of the client's public key (if the proof of posession of the
1356 corresponding private key is verified by the server).
1357 Updated to the protocol specification.
1359 * Added support of receiving the client's public key's
1360 fingerprint in command reply in client library. Affected
1361 file is lib/silcclient/command_reply.c, and
1362 lib/silcclient/idlist.[ch].
1364 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1366 * Do not send over 128 chars long nickname to the server
1367 in NICK command. Affected file lib/silcclient/command.c.
1369 * Do not send over 256 chars long channel names to the server
1370 in JOIN command. Affected file lib/silcclient/command.c.
1372 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1374 * Assure that silc_server_close_connection cannot be called
1375 twice for same socket context. Affected file is
1378 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1380 * Send error message to application if opening file for
1381 writing during file transfer fails. Affected file is
1382 lib/silcclient/client_ftp.c.
1384 Remove all file transfer sessions for a client that we're
1385 removing from ID cache.
1387 Affected file is lib/silcclient/client_ftp.c.
1389 * Fixed silc_net_addr2bin to return correct address. Affected
1390 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1392 * Fixed file transfer session removing on signoff notify.
1393 Affected file irssi/src/silc/core/silc-servers.c.
1395 * Added the SilcClientFileError to be returned in the monitor
1396 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1397 Affected file lib/silcclient/silcapi.h.
1399 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1401 * Fixed a crash in silc_client_ftp_free_sessions and
1402 silc_client_ftp_session_free_client. Affected file
1403 lib/silcclient/client_ftp.c.
1405 * Added `disabled' field in the SilcChannelEntry in the server
1406 to indicate if the server entry is disabled. Affected file

1416 * Fixed a crash in client resolving in client_prvmsg.c in
1417 client library. Affected file lib/silcclient/client_prvmsg.c.
1419 * Do not actually remove the client directly from ID cache
1420 during SERVER_SIGNOFF, but invalidate it. This way we
1421 preserve the WHOWAS info for the client. Affected file
1422 silcd/server_util.c.
1424 * Fixed SERVER_SIGNOFF notify handling in the server. The
1425 server is now able to process incoming SERVER_SIGNOFF notify
1426 for a server that it doesn't even know about. It will remove
1427 the clients provided in the notify. Affected file
1428 silcd/packet_receive.c.
1430 * Check for partial packet in data queue after every packet that
1431 was found from the queue. Return and wait for more data if
1432 there is partial data in queue. Affected file is
1433 lib/silccore/silcpacket.c.
1435 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1437 * Added SilcClietFileError enum to indicate error in
1438 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1439 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1440 Affected files lib/silcclient/silcapi.h and
1441 lib/silcclient/client_ftp.c.
1443 * Check that newsize in silc_buffer_realloc is larger than
1444 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1446 * Added better monitor of file transfers. It now monitors
1447 key agreement protocol during the file transfer too. Added
1448 error reporting too. Affected files
1449 irssi/src/silc/core/silc-servers.c,
1450 irssi/src/fe-common/silc/module-formats.[ch].
1452 * Wrote a help file for FILE command.
1454 * Added silc_rng_global_get_byte_fast to get not-so-secure
1455 random data as fast as possible. Random data is read from
1456 /dev/urandom if available and from the SILC RNG if not
1457 available. It is used in padding generation. Affected file
1458 lib/silccrypt/silcrng.[ch].
1460 * All packets in client library are now processed synchronously.
1461 Optimized packet processing a lot. Affected file
1462 lib/silcclient/client.c.
1464 * All server connection packets are processing synchronously
1465 now in server, to optimize packet processing. Affected file
1468 * Include files are installed now only in Toolkit distribution
1469 if make install is given. Affected files: all Makefile.am's.
1471 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1473 * Assure that silc_client_notify_by_server_resolve does not
1474 resolve the client information multiple times. If it cannot
1475 be found by the first it cannot be found at all. Affected
1476 file lib/silcclient/client_notify.c.
1478 * Fixed WHOWAS command reply calling. Affected file
1479 lib/silcclient/command_reply.c.
1481 * Removed all references to silc_idlist_get_client from the
1482 Irssi SILC client since that call is internal call used by
1483 the library. The Irssi SILC client will use now client
1484 retrieval functions found in silcapi.h.
1486 * Fixed a bug in resolving nickname info before sending
1487 private message. It used freed memory. Affected file
1488 irssi/src/silc/core/silc-servers.c.
1490 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1492 * Assure my_channels statistics cannot go negative in server.
1493 Affected files silcd/server.c, silcd/server_util.c.
1495 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1509 * Added silc_net_localip to return local host's IP address.
1510 Affected file lib/silcutil/silcnet.[ch].
1512 * If key exchange or rekey protocol is active for a connection
1513 parse all packets syncronously since there might be packets
1514 in packet queue that we are not able to process without first
1515 processing packets before them. Affected file silcd/server,
1516 lib/silcclient/client.c.
1518 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1519 whether library should continue processing the packet.
1520 Affected file lib/silccore/silcpacket.h.
1522 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

1551 lib/silcutil/silcutil.[ch].
1553 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1555 * Resolve the client info when received private message or
1556 channel message for a client which nickname we don't know.
1557 Affected files lib/silcclient/client_prvmsg.c and

1566 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1567 is incomplete and is being resolved, it won't be resolved
1570 Make sure also that USERS command reply does not resolve
1571 twice information. Affected file is
1572 lib/silcclient/command_reply.c.
1574 Make sure that silc_client_get_clients_by_list does not
1575 resolve twice same information.
1577 * Check for valid client->id in the silc_server_free_client_data.
1578 Affected file silcd/server.c.
1580 * Fixed /GETKEY nick@server not to crash if the server entry
1581 is not found. Affected file lib/silcclient/command.c.
1583 * Fixed the silc_server_check_cmode_rights to check the
1584 requested modes correctly. Affected file silcd/command.c.
1586 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1588 * Better checks for non-printable chars in nick added.
1589 Affected file silcd/command.c.
1591 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1593 * Call the silc_server_udpate_servers_by_server in the
1594 primary router that comes back online in the backup resuming
1595 protocol. Otherwise it routes packets wrong. Affected file
1596 silcd/server_util.[ch], silcd/server_backup.c.
1598 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1600 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1601 lib/silcutil/silcbuffmt.[ch].
1603 * Redefined the SILC packet header to include the padding
1604 length. Affected file lib/silccore/silcpacket.[ch].
1606 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1607 length for maximum padding up to 128 bytes). Affected
1608 file lib/silccore/silcpacket.h.
1610 * Removed all backwards support for old 0.5.x MAC thingies.
1611 The SILC packet header change makes it impossible to be
1612 backwards compatible.
1614 * Send the ENDING packet with timeout in the backup resuming
1615 protocol. This is to assure that all routers has connected
1616 to the primary router. Affected file silcd/server_backup.c.
1618 * Changed the RNG to take the first IV from random data. It
1619 used to take it from zero actually. Changed the RNG also
1620 to use /dev/urandom during session. /dev/random is used
1621 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1623 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1625 * Changed the SILC packet header to have the first two bytes
1626 (the packet length) encrypted. Affected files aroung the
1627 code tree, lib/silccore/silcpacket.[ch]. Removed the
1628 SilcPacketCheckDecrypt callback. It is not needed anymore
1629 since the silc_packet_receive_process will determine now
1630 whether the packet is normal or special.
1632 * Implemented the unidirectional MAC keys. Affected files
1633 lib/silcske/silcske.c, silcd/protocol.c and
1634 lib/silcclient/protocol.c.
1636 * Implemented the packet sequence number to the MAC computation.
1637 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1638 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1639 lib/silcclient/protocol.c.
1641 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1643 * Allow backup router to announce servers. All servers
1644 announced by backup router are added to the global list
1645 automatically. Update hte server's socket to our primary
1646 router also when backup router announces a server.
1647 Affected file silcd/packet_receive.c.
1649 * Do not update the client->router in the function
1650 silc_server_udpate_clients_by_server if the client is on
1651 global list. We might fail to find any specific server
1652 for locally connected clients and local cell clients. They
1653 should still use the `from' and not `to' as client->router.
1654 This fixes backup router resuming protocol. Affected file
1655 silcd/server_util.c.
1657 * Decrease channel statistics count only if the channel
1658 deletion worked. Affected files are silcd/server.c and
1659 silcd/server_util.c.
1661 * Added silc_server_update_servers_by_server to update origin
1662 of all server entries. Used during backup router protocol.
1663 Affected files silcd/server_util.[ch], silcd/server.c. and
1664 silcd/backup_router.c.
1666 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1667 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1668 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1669 lib/silccrypt/silchmac.c.
1671 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1673 * Assure that router cannot reroute the same channel message
1674 to the sender. Affected file silcd/packet_receive.c.
1676 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1678 * Made better checks that the channel message is not sent
1679 to the router it came from. Affected file is
1680 silcd/packet_send.c. Fixed memory leak too.
1682 * Announce informations for incoming router connection, but
1683 only after checking if it is replaced by backup router.
1684 Affected file silcd/packet_receive.c.
1686 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1688 * Fixed the backup resuming protocol to work in multiple
1689 router environment. Affected file silcd/server_backup.c.
1691 * Route packet only to one router in the function
1692 silc_server_packet_send_to_channel. Affected file is
1693 silcd/packet_send.c.
1695 * Fixed silc_server_send_notify_dest to set the broadcast
1696 flag. Fixed the silc_server_send_notify_topic to actually
1697 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1698 Affected file silcd/packet_send.c.
1700 * Changed the SFTP Filesystem interface. Changed the
1701 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1702 the filesystem operation function. The SilcSFTPFilesystem
1703 is now a context that is allocated by all filesystem allocation
1704 functions and it already includes the operations structure
1705 and filesystem specific context. It is given as argument
1706 now to the silc_sftp_server_start. This made the interface
1707 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1708 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1710 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1712 * Changed the backup router adding and getting interfaces
1713 in the server. The router that will be replaced by the
1714 specified backup router is now sent as argument. Affected
1715 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1718 * Added silc_net_addr2bin_ne to return the binary form of
1719 the IP address in network byte order. Affected files
1720 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1722 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1724 * Check for existing server ID in silc_server_new_server
1725 and in silc_server_connect_to_router_final and remove the
1726 old entry if it exists. Affected file silcd/packet_receive.c,
1729 * Send the channel message always to only one router, either
1730 in upstream or downstream. Affected file is
1731 silcd/packet_send.c.
1733 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1735 * Wrote the definition of the backup resuming protocol to the
1736 protocol specification.
1738 * Removed one redundant channel key generation from normal
1739 server during joining procedure. Removed one redundant
1740 channel key sending from server to router during joining
1741 procedure. Affected file silcd/command.c.
1743 * Made minor bugfixes to the backup router resuming protocol.
1744 Affected file silcd/server_backup.c, server.c.
1746 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1748 * Added --disable-asm configuration option. Affected files
1749 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1752 * Implemented the backup resuming protocol that is used to
1753 resume the primary router position in the cell after the
1754 primary router comes back online. Affected files
1755 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1756 and silcd/server_util.[ch].
1758 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1760 * Sleep two (2) seconds after sending QUIT command to server.
1761 Affected file lib/silcclient/command.c.
1763 * Assure that if outgoing data buffer is pending do not force
1764 send any data. Affected file silcd/packet_send.c.
1766 * Assure that if outgoing data buffer is pending do not force
1767 send any data. Affected file lib/silcclient/client.c.
1769 * Implemented the backup router support when the primary router
1770 goes down. The servers and routers can now use the backup
1771 router as new primary router without loosing connectivity.
1773 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1775 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1776 in the server to indicate disabled entry. All data read
1777 from the connection will be ignored and no data is sent
1778 for entry that is disabled. Affected files are
1779 silcd/idlist.h, silcd/server.c.
1781 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1783 * Created SFTP client and server test programs in the
1784 lib/silcsftp/tests directory.
1786 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1788 * Implemented memory filesystem (virtual filesystem) for
1789 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1792 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1794 * Implemented the SFTP (SSH File Transfer Protocol) to the
1795 lib/silcsftp. It includes SFTP client and SFTP server
1798 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1800 * Moved lib/silccore/silcprotocol.[ch] to the
1801 lib/silcutil library.
1803 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1804 take variable argument list pointer as argument. Affected
1805 file lib/silcutil/silcbuffmt.[ch].
1807 * Added silc_buffer_set function that is used to set data
1808 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1809 Affected file lib/silcutil/silcbuffer.h.
1811 * Changed various routines in the core library to use the new
1812 silc_buffer_set instead of allocating new buffer only for
1815 * Added 64-bit value formatting and unformatting support to the
1816 silc_buffer_[un]format routines. Affected file is
1817 lib/silcutil/silcbuffmt.[ch].
1819 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1820 to includes/bitmove.h.
1822 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1824 * Fixed channel user mode saving in client library. Affected
1825 file lib/silcclient/command[_reply].c.
1827 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1829 * Defined the file transfer to the SILC Protocol. Added
1830 new packet type SILC_PACKET_FTP and defined File Transfer
1831 Payload. The mandatory file transfer protocol is SFTP
1832 (SSH File Transfer Protocol). Affected file in addition
1833 of the internet draft is lib/silccore/silcpacket.h.
1835 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1836 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1837 is used as part of backup router protocol when the primary
1838 router of the cell is back online and wishes to resume
1839 the position as primary router.
1841 * Redefined the MAC generation keys in the protocol. The
1842 same key is not used anymore in both direction. Both
1843 direction will now use different keys for sending and
1844 receiving. This fixes a potential security flaw. This
1845 change causes incompatibilities in the protocol.
1847 * Redefined also the MAC computation from the packet.
1848 An packet sequence number is now added to the MAC
1849 computation. This prevents possible replay attacks against
1850 the protocol. This change too causes incompatibilities
1853 Added `sequence' field to the SilcPacketContext to hold
1854 the current sequence number for the packet.
1856 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1858 * Added `created' field to the SilcIDListData in the file
1859 silcd/idlist.h to indicate the time when the entry was
1862 * Added `created' field to the SilcChannelEntry too. Affected
1863 file silcd/idlist.h.
1865 * Added `creation_time' aguments to all the announcement functions
1866 in the server. If it is provided then only the entries that
1867 was created after the provided time frame are actually
1868 announced. Affected file silcd/server.[ch].
1870 * The protocol says that the Channel ID's IP address must be
1871 based on the router's IP address. Added check for this in
1872 the silc_server_new_channel when processing incoming New Channel
1873 Payload. Affected file silcd/packet_receive.c.
1875 * Print out the correct version with --version in SILC client.
1876 Affected file irssi/src/silc/core/silc-core.c.
1878 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1880 * Fixed WHOWAS command to check for completnes of the client
1881 entry always, not just when the command is coming from client.
1882 Affected file silcd/command.c.
1884 * Added new function silc_server_packet_queue_purge to purge the
1885 outgoing data queue to the network. After the function returns
1886 it is guaranteed that the outgoing packet queue is empty.
1887 Affected file silcd/packet_send.[ch].
1889 * Purge the outgoing packet queue in the rekey protocol's final
1890 callback to assure that all rekey packets go to the network
1891 before quitting the protocol. Affected file silcd/server.c.
1893 * Added silc_client_packet_queue_parse as similar function as
1894 in server to the client library. The affected file is
1895 lib/silcclient/client.c.
1897 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1899 * Splitted silcd/server.c and created silcd/server_util.[ch]
1900 for utility functions.
1902 * Added new socket flag SILC_SF_DISABLED to indicate that the
1903 connection is open but nothing can be sent to or received from
1904 the connection. Affected file lib/silcutil/silsockconn.[ch].
1905 The checking for disabled socket is checked in the low level
1906 silc_socket_write and silc_socket_read functions.
1908 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1910 * Allow only nicknames and channel names that fits into the
1911 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1913 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1915 * When processing JOIN command reply in server check that if
1916 the channel exists in our global list we'll move it the local
1917 list. Affected file silcd/command_reply.c.
1919 * Fixed the check whether client is joined on the channel already
1920 in JOIN command. Affected file lib/silcclient/command.c.
1922 * Fixed the JOIN command reply to check whether the channel
1923 already exists. Affected file lib/silcclient/command_reply.c.
1925 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1927 * Added silc_ske_status_string to map the SKE error numbers
1928 to readable strings. The affected files are
1929 lib/silcske/silcske[_status].[ch].
1931 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1933 * Do not show the private channels on the WHOIS channel list
1934 as it is not allowed by the protocol. The affected file is
1937 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1939 * Assure that the packet length digged from the actual packet
1940 is something sensible in the silc_packet_decrypt_rest_special
1941 in lib/silccrypt/silcpacket.c.
1943 * Free and NULL the allocated pointer in silc_hmac_alloc if
1944 the HMAC allocation fails. The affected file is
1945 lib/silccrypt/silchmac.c.
1947 * Print the selected security properties to the log files in
1948 the server. Affected file silcd/protocol.c.
1950 * Add SKE's reference counter even if calling the completion
1951 callback manually. Otherwise it goes negative, although it
1952 does not cause any problems. The affected file is
1953 lib/silcske/silcske.c.
1955 * Remove the client entry with short timeout after giving the
1956 KILL command. Affected file lib/silcclient/command.c.
1958 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1959 case all found clients are already disconnected (WHOWAS would
1960 found them) in the server. Affected file silcd/command.c.
1962 * Update the last_receive (time of last data received) to be
1963 updated only when received private or channel message so that
1964 the idle time showed in WHOIS makes more sense.
1966 * Added boolean field `valid' in to the SilcClientEntry in the
1967 client library to indicate whether the entry is valid or not.
1968 This fixes the nickname change bug on channel when changing
1969 the nickname to be same than the old (like nick to Nick) the
1970 nickname formatter doesn't set the new nick anymore to Nick@host.
1971 Affected file lib/silcclient/idlist.[ch].
1973 * Now actually fixed the nickname changing on disconnection.
1974 Added new function silc_change_nick to the Irssi SILC Client.
1975 Affected file irssi/src/silc/core/client_ops.c,
1976 irssi/src/silc/core/silc-nicklist.[ch].
1978 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1980 * Check that the public key exists in the GETKEY command before
1981 trying to encode it. Affected file silcd/command.c.
1983 * Print some notifications on received public keys with GETKEY
1984 command in the Irssi SILC Client. Affected files are
1985 irssi/src/fe-common/silc/module-formats.[ch],
1986 irssi/src/silc/core/client_ops.c.
1988 * Use IDENTIFY command to resolve the server information in the
1989 GETKEY command instead of INFO command. Affected file
1990 lib/silcclient/command.c.
1992 * All command reply functions in the client library now calls
1993 the pending command reply callbacks even if an error has
1994 occurred. The server has done this a long time and now it was
1995 time to move the client library to this as well. Now all
1996 errors can be delivered back to the pending command reply
1997 callbacks if necessary. Affected files are
1998 lib/silcclient/command[_reply].[ch].
2000 * Change the nickname on disconnection back to the username
2001 because in reconnect the server will enforce it to it anyway.
2002 Affected file irssi/src/silc/core/silc-servers.c.
2004 * Fixed a config file parsing bug in the Irssi SILC client.
2005 Affected file irssi/src/silc/core/clientconfig.c.
2007 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2009 * When printing the channel mode on JOIN, verify that the
2010 channel key and channel's HMAC are valid. Affected file
2011 irssi/src/silc/core/client_ops.c.
2013 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2015 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2016 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2017 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2019 * Removed channel key rekey task deleting from the function
2020 silc_server_save_channel_key. Affected file silcd/server.c.
2021 Added explicit timeout task context instead that is used to
2022 delete the task if we are registering a new task before the
2023 new task has elapsed.
2025 * When channel key rekey occurs the client library now saves
2026 the old channel key for a short period of time (10 seconds) and
2027 is able to use it in case some is still sending channel
2028 messages encrypted with the old key after the rekey. Affected
2029 file lib/silcclient/[idlist.h|client_channel.c].
2031 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2033 * Added check to the silc_server_new_id_real to not accept
2034 new ID if it is the sender's own ID. Affected file is
2035 silcd/packet_receive.c.
2037 * Assure that we do not announce ourself or the one we've
2038 sending our announcements when we're router and are announcing
2039 servers to our primary router. Affected file silcd/server.c.
2041 * Fixed silc_server_command_identify_check_client to assemble
2042 correct WHOIS packet. It send corrupted WHOIS packet and
2043 caused problem with router to router connections. Affected
2044 file silcd/command.c.
2046 Fixed also silc_server_command_whois_check the same way
2047 as for the IDENTIFY command.
2049 * Added new SilcIDListStatus to the server in the SilcIDListData
2050 structure. The status now includes the current status of
2051 the entry (like registered, resolved etc.). Affected file
2052 silcd/idlist.[ch]. Defined a bunch of different status types
2053 as well. This replaced the old boolean registered field as well.
2055 Added resolve_cmd_ident field to the SilcClientEntry structure
2056 too so that if the entry is for example being resolved so
2057 another command may attach to the same pending command reply
2058 without requiring to resolve the same entry again. This concept
2059 should optimize the WHOIS and the IDENTIFY resolving under
2060 heavy load by taking away unnecessary resolving for entries
2061 that are being resolved already.
2063 Added support for adding multiple pending commands for one
2064 command idenfier. Affected file silcd/command[_reply].[ch].
2066 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2067 before deleting the data. Otherwise the hash table will have
2068 freed data in comparison functions. Affected file is
2069 silcd/command_reply.c.
2071 * Fixed silc_idlist_replace_client_id to add the new entry to
2072 the cache with NULL nickname. Otherwise there will be invalid
2073 memory as the nickname after the nickname is freed. Affected
2074 file silcd/packet_receive.c.
2076 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2077 saved into wrong slots because the previous number of entries
2078 was not taken into account. Affected file silcd/idlist.c.
2079 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2081 * If we are router and we receive JOIN notify to a channel that
2082 does not have any users then notified client is marked as the
2083 channel founder, as it is it. The affected file is
2084 silcd/packet_receive.c
2086 * Added to the extended hash table API's table_del_*ext functions
2087 the destructor as argument too, so that the caller can decide
2088 which destructor to use or whether to use destructor at all.
2089 Affected file lib/silcutil/silchashtable.[ch].
2091 * Fixed ID Cache purging. It actually deleted the entries from
2092 the hash table after the data was freed. The hash table ended
2093 up comparing freed memory. The affected file is
2094 lib/silccore/silcidcache.c.
2096 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2098 * Fixed Irssi SILC client's KILL command's HELP syntax.
2100 * The USERS command now resolves the detailed user information
2101 if the userinfo field is missing. Affected file is
2102 lib/silcclient/command_reply.c.
2104 * Do not print error in silc_file_read if the read file does
2105 not exist. Just silently return NULL. Affected file is
2106 lib/silcutil/silcutil.c.
2108 * Fixed the silc_log_output to not wine about NULL filename
2109 and to not create some bogus " " filename. Affected file is
2110 lib/silcutil/silclog.c.
2112 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2114 * Fixed various printing bugs on the user interface in the
2115 Irssi SILC Client. Minor changes that were forgotten from
2118 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2120 * Fixed the configure.in.pre and the compilation and distribution
2121 environment to support the new autoconf 2.52. That version is
2122 now required to compile the CVS trunk.
2124 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2126 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2127 to generally parse user@fqdn format strings. Affected file
2128 lib/silcutil/silcutil.c.
2130 * Added nickname_format and nickname_force_format fields to the
2131 SilcClientParams structure. The first one defines the format
2132 for the nicknames that the library will enforce if the receives
2133 multiple same nicknames. The second one is boolean value and
2134 can be used to force the library to always enforce the format
2135 to the nicknames regardles whether there are multiple nicknames
2136 or not. This configurable formatting was employed to flexibly
2137 support accessing multiple nicknames from the user interface.
2138 The userinterface can now set the nicknames to what ever format
2139 they prefer. Affected file lib/silcclient/silcapi.h.
2141 Added function silc_client_nickname_format to the file
2142 lib/silcclient/idlist.c. It performs the nickname formatting.
2144 Added new field `hostname´ to the SilcClientEntry context.
2145 It holds the hostname of the client. Affected file is
2146 lib/silcclient/idlist.h.
2148 * Irssi SILC Client sets the nicknames in nick@hostn format.
2149 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2150 irssi/src/silc/core/silc-core.c.
2152 The WHOIS printing now also shows both the real nickname and
2153 the formatted nickname so that user knows how to access the
2154 user if there are multiple same nicknames cached. Affected
2155 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2156 printing formatting too to take the hostname now as a separate
2157 argument. The Affected file is
2158 irssi/src/fe-common/silc/modules-formats.[ch].
2160 * Changed the silc_client_get_clients_local to accept the formatted
2161 nickname as argument. It accepts the real nickname too but the
2162 formatted nickname can be used to find the true entry from
2163 multiple entries. Affected file lib/silcclient/silcapi.h and
2164 lib/silcclient/idlist.c.
2166 * Added nickname_format_parse field to the SilcClientParams.
2167 It is a callback function provided by the application to parse
2168 the nickname out of the formatted nickname string. The library
2169 calls it to get the nickname from the formatted string. Since
2170 the application generally knows better the format of the nickname
2171 string it parses it instead of the library, even though library
2172 encodes the formatted string. If the callback function is not
2173 provided then the library will use the string as is. The
2174 affected file is lib/silcclient/silcapi.h.
2176 * All the nickname strings passed to the client library in
2177 commands are now expected to be formatted nickname strings.
2178 If the command does not support the formatted nickname string
2179 it will assume that the sent string is the actual nickname.
2180 Affected file lib/silcclient/command.c.
2182 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2184 * Added public key authentication support to OPER and SILCOPER
2185 commands in the client library. Affected file is
2186 lib/silcclient/command.c.
2188 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2190 * Changed the get_auth_methdod client operation to be asynchronous.
2191 It can be async if the application resolves the authentication
2192 method from the server during the negotiation. Added new
2193 SilcGetAuthMeth completion callback that the application will
2194 call after resolving the authentication method.
2196 Added function silc_client_request_authentication_method that
2197 the application can use to resolve the authentication method
2198 from the server. Added also SilcConnectionAuthRequest callback
2199 that the library will call after the server has replied. The
2200 application can call this function if it does not know the
2201 current authentication method.
2203 Affected files are lib/silcclient/client.c and
2204 lib/silcclient/silcapi.h.
2206 * The Irssi SILC client now automatically resolves the authentication
2207 method incase any configuration information is not present (and
2208 currently there never is). The affected file is
2209 irssi/src/silc/core/client_ops.c.
2211 * Fixed public key authentication from the client library.
2212 Affected file lib/silcclient/protocol.c. Changed also the
2213 protocol specification about the public key authentication in
2214 the connection authentication protocol. The actual data to be
2215 signed is now computed with a hash function before signing.
2217 * Fixed the public key authentication from the server as well.
2218 Affected file silcd/protocol.c.
2220 * Removed the mlock()'s from the memory allocation routines.
2221 Affected file lib/silcutil/silcmemory.c. The ./configure does
2222 not check anymore for the mlock(). Affected file is
2225 * Fixed USERS command in server to allow the execution of the
2226 command for private and secret channels if the client sending
2227 the command is on the channel. Affected file silcd/command.c.
2229 * Fixed silc_client_get_clients_local to return the clients
2230 count correctly. It could return wrong value. Affected file
2231 lib/silcclient/idlist.c.
2233 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2235 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2236 types. The assembler optimizations seemed not to like 64-bit
2237 data types. The assmebler optimizations thus are now enabled
2238 also for BSD systems as opposed to only enable them for Linux.
2240 * Do not check for threads at all on BSD systems. Affected
2241 file configure.in.pre.
2243 * Removed -n and -h options from the Irssi SILC Client since
2244 they are not used in silc.
2246 * Fixed the prime generation to assure that the first digit
2247 of the generated random number is not zero since our conversion
2248 routines does not like number strings that starts with zero
2249 digit. If zero digit is seen the random number is regenerated.
2250 This caused some corrupted RSA keys when the zero first digit
2251 was met. Affected file lib/silcmath/silcprimegen.c.
2253 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2255 * Fixed WIN32 configuration in the ./configure script.
2256 Fixed to include xti.h on environments that has it.
2257 Patches by Carsten Ilchmann and andrew.
2259 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2261 * Changed the silc_id_create_client_id to be collision
2262 resistant. It is now assured that there cannot be created
2263 two same client ID's. I suspect that some weird bugs in
2264 the server were actually caused by duplicate Client IDs.
2265 Affected file silcd/serverid.[ch]. A router receiving
2266 new ID now also assures and informs the sending server
2267 if the ID caused collision.
2269 * Changed the silc_id_create_channel_id to also assure that
2270 there are no collisions.
2272 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2274 * Statement about ignoring the Mutual Authentication flag when
2275 performing rekey with PFS was a bit misleading. It is ignored
2276 if it was set in the initial negotiation, it cannot be even
2277 set in the rekey. Fixed in the ke-auth draft. Started the
2278 new versions of the protocol drafts in the doc/.
2280 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2282 * Fixed a bug in silc_client_command_identify_save when saving
2283 new channel information. The channel name was no duplicated
2284 and caused crash on exit. Affected file is
2285 lib/silcclient/command_reply.c.
2287 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2289 * Fixed the getkey command handling in the server. Send just
2290 empty OK reply to the sender if the key could not be fetched
2291 (but everything else was ok, like the key just was not available).
2292 Changed the public key parameter to optional in the protocol
2293 specs so that empty OK reply can be sent. Affected file
2296 Added a message to Irssi SILC client to tell to user if the
2297 server did not return a public key.
2299 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2301 * Fixed a channel key regeneration bug. It registered new
2302 timeout tasks exponentially until all system resources were
2303 used. Affected file silcd/server.c.
2305 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2307 * Added the SILC Document generator to the scripts/silcdoc.
2308 It can be used to generate the Toolkit Reference Manual out
2309 of the source tree. Internally it will also use the RoboDoc
2310 generator now imported in util/robodoc.
2312 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2314 * Added couple of return's in rekey protocol if error orccurred
2315 during the protocol. The execution must be terminated.
2316 Affected file silcd/protocol.c. Also, terminate the protocol
2317 always with timeout.
2319 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2321 * The client's Client ID was created initally from the wrong
2322 nickname (it could have been in format nick@host) in the
2323 silc_server_new_client. Affected file silcd/packet_receive.c
2325 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2327 * Added some SILC_LOG_ERROR's to various error conditions
2328 if client could not be added to ID cache. Affected files
2329 silcd/packet_receive.c and silcd/server.c.
2331 * When client's sock->user_data is freed, NULL also the
2332 client->router and client->connection pointers. Added check
2333 for these pointers being NULL to various places around the
2334 code. Affected file silcd/server.c.
2336 * Added client->data.registered == TRUE checks to various
2337 places around the code to assure that unregistered client's
2338 are not handled when it is not allowed. Affected file
2341 * Added `bool registered' fields to all
2342 silc_idlist_[server|client]_get_* routines to indicate whether
2343 the fetched client needs to be registered or not. Affected
2344 file silcd/idlist.[ch].
2346 * Add your own entry as registered to the ID cache in the
2347 server. Affected file server.c.
2349 * Fixed a bug in silc_server_new_server. The SilcServer was
2350 set as the new server's context instead of SilcServerEntry.
2351 This naturally caused some weird bugs.
2353 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2355 * Do not delete the channel rekey task when adding it
2356 for in silc_server_create_channel_key.
2358 * Changed the silc_server_create_channel_key to return
2359 TRUE or FALSE to indicate the success of the channel key
2362 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2364 * Fixed MSVC++ project files and added missing files to
2365 Makefiles under win32/.
2367 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Do not add TCP_NODELAY flag if the operating system
2370 does not have it defined. Affected files are
2371 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2373 * Fixed buffer overflow from Irssi SILC Client. Affected
2374 file irssi/src/fe-common/core/themes.c.
2376 * Fixed double free in client library in the file
2377 lib/silcclient/client.c when disconnecting from server.
2379 * Applied double free patch from cras to Irssi SILC client.
2380 Affected files irssi/src/core/[modules/expandos].c
2382 * Fixed the disconnection handling to Irssi SILC Client.
2383 The application must call silc_client_close_connection
2384 in ops->connect client operation in case of failure of
2385 the connection. Affected file is
2386 irssi/src/silc/core/client_ops.c.
2388 * Do not set sock->protocol to NULL in the function
2389 silc_client_close_connection after executing the protocol's
2390 final callback since the sock might not be valid anymore.
2391 Affected file lib/silcclient/client.c.
2393 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2395 * Do not enable SILC_THREADS if the linking with libpthread
2396 did not happen. Affected file configure.in.pre.
2398 * Added notion to protocol specification that server must
2399 verify the sent authentication payload with CMODE when
2400 setting the channel founder key. Implemented it to the
2401 server. Affected file silcd/command.c.
2403 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2405 * Added _EXTRA_DIST SILC distribution variable to the
2406 distributions file. It is used to conditionally add extra
2407 files or directories to the specific distribution. Affected
2408 files ./prepare, Makefile.am.pre and distributions.
2410 Removed the `_' from the start of the distribution names.
2413 * Added README.WIN32 for instructions to compile the Toolkit
2416 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2418 * Fixed a double free in disconnection in the server. Affected
2419 file is silcd/server.c.
2421 * Fixed the lib/silcske/groups.c to work now also with GMP
2422 MP library. The string conversion did not work when using
2423 specific base and the base is indicated in the string as well.
2425 * Created win32/ directory which now includes MSVC++ specific
2426 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2427 It will appear only in the toolkit distribution
2429 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2431 * Changed the key material distribution function in case when
2432 the hash output is too short. The data is now concatenated
2433 a bit differently than it used to. Made the change to the
2434 SKE protocol specification.
2436 * Added better GMP detection to configure.in.pre. A patch
2439 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2441 * Fixed a minor bug in SKE that might cause some problem on
2442 some platforms. Affected file lib/silcske/silcske.c.
2444 * Added the cookie checking for initiator in the SKE. It checks
2445 that the responder returns the sent cookie unmodified. The
2446 affected file is lib/silcske/silcske.c. Added new SKE
2447 error type INVALID_COOKIE that can be sent during the
2448 negotiation. Fixed some memory leaks as well.
2450 * Added the "invalid cookie" error message to Irssi SILC client's
2453 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * Added `task_max' field to the SilcClientParams to indicate
2456 the maximum tasks the scheduler can handle. If set to zero,
2457 default values are used. Affected file lib/silcclient/silcapi.h.
2459 * Fixed memory leaks in silc_client_close_connection. Affected
2460 file lib/silcclient/client.c.
2462 * Added silc_client_del_client_entry to client library to free
2463 all memory of given client entry. Affected file is
2464 lib/silcclient/idlist.[ch].
2466 * Added new functions silc_client_del_channel and
2467 silc_client_del_server to delete channel and server entries.
2468 Affected file lib/silcclient/[silcapi.h/idlist.c].
2470 * Removed silc_client_del_client_by_id from silcapi.h.
2472 * Fixed the INFO command to return the server's own info
2473 correctly when querying by Server ID. Affected file is
2476 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2478 * Removed the non-blocking settings in WIN32 code in the
2479 silc_sock_[read/write] and added SleepEx instead. Affected
2480 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2481 of input data is now checked with FIONREAD and ioctlsocket.
2483 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2485 * Call silc_schedule_task_del_by_context in the
2486 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2487 Affected file lib/silccore/silcprotocol.c.
2489 * Call silc_protocol_cancel for active protocols in the
2490 silc_server_close_connection if the funtion
2491 silc_server_free_sock_user_data has not been called.
2492 Affected file silcd/server.c.
2494 * Generic tasks cannot be deleted using the del_by_fd
2495 task deleting function since generic tasks does not match
2496 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2498 * Added a notion to SILCOPER help file that the SILCOPER works
2499 only on router server, not on normal server.
2501 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2503 * Added for WIN32 support for the new scheduler as well.
2504 Affected file lib/silcutil/win32/silcwin32schedule.c.
2506 * Fixed the SHA1 implementation to work on various platforms.
2508 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2510 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2511 API. It is part of the scheduler now. Everything else is
2512 as previously but some functions has changed their names.
2513 Checkout the lib/silcutil/silcschedule.h for the interface.
2514 Updated all applications to use the new interface. Affected
2515 files are lib/silcutil/silcschedule.[ch].
2517 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2519 * Found a bug in the SKE implementation. The HASH value,
2520 specified by the protocol, was not computed correctly. The
2521 public key of the responder was not added to the computation
2522 even though it is mandatory. Affected file lib/silcske/silcske.c.
2523 This unfortunately causes incompatibilities with older
2524 clients and servers.
2526 * Added WIN32 specific network init and uninit functions:
2527 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2528 the Winsock2. Affected file lib/silcutil/silcnet.h and
2529 lib/silcutil/win32/silcwin32net.c.
2531 * Set the socket always to nonblocking mode on WIN32 after
2532 reading data or writing data. Affected file is
2533 lib/silcutil/win32/silcwin32sockconn.c.
2535 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2537 * Fixed various compilation problems under WIN32. Affected
2538 files lib/silcutil/win32/silcwin32thread.c and
2539 lib/silcutil/win32/silcwin32schedule.c.
2541 * Removed all _internal.h #includes from public header
2542 files. Internal headers must never be included from
2545 Removed also the lib/silcske/payload_internal.h file.
2547 * All include files that may be needed (public and some others
2548 included by the public headers) by application developers are
2549 now copied to the ./includes directory. It does not copy any
2550 internal headers. Affected file Makefile.defines.pre and all
2551 Makefile.am's under lib/ and subdirs.
2553 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2555 * Do not change the ~/.silc directory's permissions automatically.
2556 Affected file irssi/src/silc/core/clientutil.c.
2558 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2560 * Do not cancel the protocol in silc_server_close_connection
2561 it might cause recursion. Now cancelled in the function
2562 silc_server_free_sock_user_data. Affected file silcd/server.c.
2564 * Fixed the silc_server_remove_clients_by_server to regenerate
2565 the channel keys correctly finally. Added also new function
2566 silc_server_remove_clients_channels to actually do it.
2567 Affected file silcd/server.c.
2569 * Fixed the silc_server_new_channel to not crash by giving
2570 wrong router to the new channel. Affected file is
2571 silcd/packet_receive.c.
2573 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2575 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2576 which is given as argument to the silc_client_alloc now.
2577 It can be used to configure the client and set various parameters
2578 that affect the function of the client.
2580 * The USERS command in server did not check whether the channel
2581 is private or secret. Affected file silcd/command.c.
2583 * Added new argument to the USERS command in protocol specification.
2584 The USERS command now can take the channel name as argument
2585 as well. Added support for this in client and server and
2586 updated the protocol specs.
2588 * Completed the GETKEY command in client. It can be now used
2589 to fetch also servers public key not only some clients.
2590 Affected files lib/silcclient/command[_reply].c.
2592 * Added silc_client_get_server to return server entry by the
2593 server name. Affected files lib/silcclient/silcapi.h and
2596 * Redefined the IDENTIFY command in protocol specification to be
2597 more generic. It now can be used to query information about
2598 any entity in the SILC Network, including clients, servers and
2599 channels. The query may be based either the entity's name
2600 or the ID. Added support for this in both client and server.
2602 Affected files silcd/command.c and lib/silcclient/command.c
2603 and command_reply.c.
2605 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2606 the _from_client and _from_server functions. Affected file
2609 * Added silc_client_get_channel_by_id_resolve to the file
2610 lib/silcclient/silcapi.h to resolve channel information by
2611 its ID. Added also silc_client_get_channel_by_id that
2612 does not resolve it from the server.
2614 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2616 * Added SilcServerEntry context into the client library
2617 to represent one server. The INFO command now allocates
2618 these to save the resolved server info. For now on the
2619 client library will also keep information about servers,
2620 connected and resolved with INFO.
2622 The INFO command now allocates the SilcServerEntry context
2623 and saves the server info there. The COMMAND_REPLY in
2624 the INFO now returns the parameters to application in
2625 same order as defined in the protocol specification.
2627 The entries are cached in the client->server_cache.
2629 * The INFO command is now issued after received the Client ID
2630 from the server. Affected file lib/silcclient/client.c.
2632 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2633 to the application as the mode changer might be server.
2634 It is guaranteed that NULL is not returned anymore to the
2635 application. Affected file lib/silcclient/client_notify.c.
2637 The ID Type is now also passed to the application so that
2638 it can check whether the returned entry is SilcClientEntry
2641 Added new function silc_client_get_server_by_id to return
2642 the server entry by ID. Affected files are the
2643 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2645 * Do not create the channel in the Irssi SILC Client when issuing
2646 the JOIN command but when received the sucessful JOIN command
2647 reply. Otherwise the channel might get created even though we
2648 could not join it. The Affected file is
2649 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2651 * Fixed a channel joining bug in router. The router must also
2652 check the channel modes, invite and ban lists etc. when serving
2653 the JOIN command sent by normal server. Affected file is
2654 silcd/command.c. The router now resolves the client's
2655 information from the server who sent the JOIN command if it
2656 does not know it, and processes the JOIN command only after
2659 * Changed the SilcCommandCb to take new argument; void *context2.
2660 Affected file lib/silccore/silccommand.h
2662 The second argument in the command callbacks in the server now
2663 includes the SilcServerCommandReplyContext if the command was
2664 called as pending command callback from the command reply.
2665 Otherwise it is NULL. When called as pending the status of the
2666 command reply will be checked and if it was erronous the
2667 error will be sent to the original sender of the command.
2668 This way the client always receives the error messages even
2669 though the server was actually the one who received the error
2670 when it resent the command to router, for example. Affected
2671 files silcd/command[_reply].[ch].
2673 * Fixed sending WHOWAS command's error message to client if
2674 the requested client could not be found. It was missing.
2677 * Changed the CMODE and CUMODE commands reply arguments in the
2678 protocol specification. The Channel ID is now sent in both
2679 of the commands to identify the channel. Implemented this
2680 new feature to the client and server. Affected files
2681 lib/silcclient/command_reply.c and silcd/command.c.
2683 * Made better checks for invite and ban lists in the JOIN
2684 command in server. Affected file silcd/command.c.
2686 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2688 * The server now performs the incoming host IP/DNS lookup
2689 using the silc_socket_host_lookup and thus does not block
2690 the server anymore. Affected file silcd/server.c.
2692 * Completed the multi-thread support for SILC Scheduler in
2693 the lib/silcutil/silcschedule.c.
2695 * Fixed the configure.in.pre to detect the pthread correctly
2698 * Fixed a deadlock in silc_task_queue_wakeup in the file
2699 lib/silcutil/silctask.c.
2701 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2703 * Added new function silc_schedule_wakeup that is used in
2704 multi-threaded environment to wakeup the main thread's
2705 schduler. It needs to be used when a thread adds a new task
2706 or removes a task from task queues. After waking up, the
2707 scheduler will detect the task queue changes. If threads
2708 support is not compiled in this function has no effect.
2709 Implemented the wakeup mechanism to both Unix and WIN32
2710 systems. Affected files are lib/silcutil/silcschedule.[ch],
2711 lib/silcutil/unix/silcunixschedule.c and the
2712 lib/silcutil/win32/silcwin32schedule.c.
2714 * Added new function silc_task_queue_wakeup to wakeup the
2715 scheduler by the specified task queue. Affected file
2716 lib/silcutil/silctask.[ch].
2718 * The silc_socket_host_lookup_start now wakes up the scheduler
2719 after adding the timeout task. Affected file is
2720 lib/silcutil/silcsockconn.c.
2722 * The silc_socket_host_lookup is synchronous now if the threads
2723 support is not compiled in. However, the callback is still
2724 called asyncronously through the scheduler, anyway. Affected
2725 file lib/silcutil/silcsockconn.c.
2727 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2729 * Added new function silc_socket_host_lookup to perform
2730 asynchronous IP and FQDN lookups for the socket connection.
2731 Affected files lib/silcutil/silcsockconn.[ch].
2733 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2735 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2736 that may or may not compile the mutex support in.
2738 Changed the silc_mutex_alloc interface. It allocates the
2739 mutex now to the sent pointer and returns TRUE or FALSE.
2741 Affected file lib/silcutil/silcmutex.h.
2743 * Wrote the SILC Task Queue interface to support multi-threads.
2744 Affected file lib/silcutil/silctask.[ch].
2746 * Wrote the SILC Scheduler to support multi-threads. Affected
2747 file lib/silcutil/silcschedule.c.
2749 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2751 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2752 in lib/silcutil/win32/.
2754 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2756 * Defined SILC Mutex API and SILC Thread API and implemented
2757 them for Unix. Affected files are
2758 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2759 lib/silcutil/unix/silcunixmutex.c and
2760 lib/silcutil/unix/silcunixthread.c.
2762 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2764 * Fixed the silc_server_remove_clients_by_server's channel
2765 key re-generation. The hash table handling was incorrect
2766 and would not work with many channels. Affected file is
2769 * Fixed some memory leaks around the server code.
2771 * Rewrote the silc_server_get_users_on_channel to support IPv6
2772 based Client ID's. Affected file silcd/server.c.
2774 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2775 specification. However, a separate document must be written
2776 to define the detailed signing procedure and the payload
2777 associated with the flag. Defined the flag to the
2778 lib/silccore/silcchannel.h as well.
2780 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2782 * Changed the dynamic tables to static size tables in the
2783 lib/silccrypt/silchmac.c.
2785 * Removed GCC dependencies from the code. A patch by cras.
2787 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2789 * Do not show the error "Error receiving packet bla bla"
2790 in server if it really was not an error (-2 means that reading
2791 is pending). Affected file silcd/server.c.
2793 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2795 * Fixed a possible crash in silc_server_remove_clients_by_server
2796 in silcd/server.c. Fixed there also some memory leaks.
2798 * Fixed the silc_idlist_replace_client_id. It could replace
2799 wrong key in the hash table. Affected file silcd/idlist.c.
2801 * Do not check whether there are global users on the channel
2802 if the channel->global_users is FALSE. Affected functions
2803 silc_server_remove_from_one_channel and
2804 silc_server_remove_from_channels in silcd/server.c. Also,
2805 do not check if the removed client is local as we can be
2806 sure that global client was not removed from the channel
2807 and checking for global users is not needed.
2809 * The silc_server_remove_clients_by_server now re-generates
2810 the channel keys correctly for those channels that had
2811 clients removed from them. Affected file silcd/server.c.
2813 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2815 * Found the reason of random crashes in the server. We weren't
2816 ignoring the SIGPIPE signal (which can be sent in write())
2817 and it crashed the server. Affected file silcd/silcd.c.
2819 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2821 * Assure that sock->user_data is not NULL in the function
2822 silc_server_packet_send in silcd/packet_send.c.
2824 * Disconnect the remote connection if it could not be added
2825 to any ID lists in the server. The affected file is
2828 * Check in silc_server_packet_send[_real/dest] that the
2829 socket is not disconnecting and ignore the data if it is.
2830 Affected file silcd/packet_send.c.
2832 * Define inline to __inline on native WIN32 compilation.
2833 Affected file includes/silcwin32.h.
2835 * Added some explicit type casts for inline code since MSVC
2836 require them. Affected files lib/silcutil/silcbuffer.h,
2837 lib/trq/silcdlist.h and lib/trq/silclist.h.
2839 * Print warning in log files from now on if the packet
2840 decryption fails. Affected file silcd/server.c.
2842 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2844 * Changed the `say' client operation's interface to accept
2845 new `type' argument to indicate the type of the message sent
2846 by the library. The application may filter the library's
2847 messages according the type. The affected file is the
2848 lib/silcclient/silcapi.h.
2850 * Added two new functions to lib/silcclient/silcapi.h:
2851 silc_client_del_client and silc_client_del_client_by_id.
2852 Affected file lib/silcclient/idlist.c.
2854 * Moved the clientincludes.h from includes/ to silc/ and
2855 serverincludes.h from includes/ to silcd/.
2857 * The modes for the CMODE and CUMODE are now passed as
2858 uint32 for application with COMMAND_REPLY. The affected
2859 file is lib/silcclient/command_reply.c.
2861 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2863 * /WHOIS without arguments shows client's own information.
2864 Affected file lib/silcclient/command.c.
2866 * Changed PING to not accept any arguments. The specs
2867 says that client can ping only the connected server so
2868 requiring an argument is not needed. Affected file is
2869 lib/silcclient/command.c.
2871 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2873 * Fixed a fatal bug in private message sending and reception
2874 encryption and decryption when using private message keys.
2875 The implementation was incorrect and did not follow the
2876 specification. It causd that some of the message were
2877 lost since it did not use the sending and receiving keys
2878 as the protocol suggests. This has been fixed and will cause
2879 incompatibilities with older clients when sending private
2880 message encrypted with private message keys. Affected files
2881 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2882 and various other in Irssi SILC Client.
2884 Added `responder' boolean argument to the functions
2885 silc_client_add_private_message_key[_ske] to indicate when
2886 the key is added as responder or initiator of the key
2889 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2891 * Removed the silc_ske_check_version function and created
2892 a SilcSKECheckVersion callback. Added also a function
2893 silc_ske_set_callbacks that is now used to set all SKE
2894 callbacks. The callback functions are not given to
2895 the SKE functions anymore, but this function is used to
2898 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2900 * Added `silc_version' argument to the silc_client_alloc
2901 to define the version of the application for the library.
2902 The library will use the version string to compare it
2903 against the remote host's (usually a server) version
2904 string. Affected file lib/silcclient/silcapi.h
2906 * Added the KE protocol context to Key Agreement context
2907 in client library so that we can abort the SKE if it
2908 is in process when we get timeout. Affected file is
2909 lib/silcclient/client_keyagr.c.
2911 * Do not resolve the client ID forever if it returns in the
2912 first time that such client does not exist. This was done
2913 for example with private message. Affected file is
2914 lib/silcclient/client_prvmsg.c.
2916 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2918 * Do not add regex.h for WIN32. The affected file
2919 includes/silcincludes.h.
2921 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2922 not work yet 100%. It generates the DLL's automatically
2923 when compiling with --with-win32 under cygwin.
2925 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2927 * lib/contrib/regex.c is not compiled on WIN32.
2929 * Added silc_net_get_socket_opt function to the
2930 lib/silcutil/silcnet.h.
2932 * Added includes/silcwin32.h for WIN32 specific includes
2935 * Do not use ptime structure or any of the posix process
2936 functions on WIN32 in lib/silccrypt/silrng.c.
2938 * Added silc_gettimeofday to provide generic function
2939 for struct timeval on all platforms. Added the function
2940 to lib/silcutil/silcutil.h.
2942 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2944 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2945 library as they clearly belong there. As a plus side we
2946 can make the actual socket connection routines platform
2949 Added also new generic function silc_socket_read and
2950 silc_socket_write (that used to be silc_packet_[read/write].
2951 The implementation of these are platform specific.
2953 * Added WIN32 specific routines of silc_socket_[read/write]
2954 to lib/silcutil/win32/silcwin32sockconn.c.
2956 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * Added preliminary support for native WIN32 compilation under
2959 cygwin (using the -mno-cygwin option for GCC) to the
2960 ./configure.in.pre. The --with-win32 now prepares the
2961 compilation for native WIN32.
2963 * Rewrote the SILC Scheduler interface in the file
2964 lib/silcutil/silcschedule.h. The scheduler is now context
2965 based and does not have anymore any global static scheduler.
2966 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2967 and created lib/silcutil/win32 directory for WIN32 based
2970 * Added Unix specific network routines to the
2971 lib/silcutil/unix/silcunixnet.c and the old
2972 lib/silcutil/silcnet.c includes now only generic routines.
2974 Added WIN32 specific network routines to the
2975 lib/silcutil/win32/silcwin32net.c.
2977 * Added Unix specific utility functions from the
2978 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2980 * Added WIN32 SILC Scheduler to the file
2981 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2984 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2986 * Do not handle JOIN notify in the server if the target client
2987 is not registered (idata->registered == FALSE). The affected
2988 file is silcd/packet_receive.c.
2990 * Update the nickrec->founder in event_cumode in the Irssi SILC
2991 client. Affected file irssi/src/silc/core/silc-channels.c.
2993 * Fixed the CUMODE_CHANGE notify handling in the server when
2994 server and router are announcing their clients on channels.
2995 Now the mode changes are saved and notified correctly. The
2996 affected file is /silcd/packet_receive.c.
2998 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2999 They really did not replace the cache entry in the ID Cache.
3000 Now they do that. Affected file silcd/idlist.c.
3002 * Fixed the KICK notify handling in the Irssi SILC client to
3003 update the channel records so that the kicked client does not
3004 appear to be on the channel. The affected file is
3005 irssi/src/silc/core/silc-channels.c.
3007 * Always update the conn->current_channel when executing command
3008 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3010 * Fixed the KILL notify handling in Irssi SILC client to remove
3011 the killed client on all channels.
3013 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3015 * Fixed the silc_parse_command_line to remove extra spaces
3016 from the start and end of the arguments. Affected file is
3017 lib/silcutil/silcutil.c.
3019 * Cancel and free any active protocol in the function
3020 silc_server_close_connection. Affected file silcd/server.c.
3022 * Cancel and free any active protocol in the function
3023 silc_client_close_connction. Affected file is
3024 lib/silcclient/client.c.
3026 * Do not execute the KILL command for clients that are in
3027 history (ie. they are not in the network). Affected file is
3030 * Fixed KILL notify handling, client does not crash anymore.
3031 Affected file irssi/src/silc/core/silc-channels.c.
3033 * Reduced the default packet buffer size from 2048 to 1024 in
3034 lib/silccore/silcpacket.c.
3036 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3037 counter to the SKE context that is incresed when the SKE library
3038 performs async operation outside the library. If the outside
3039 process frees the SKE context and FREED status will be set
3040 and the library will detect after the sync operation that the
3041 libary is freed. The affected files are
3042 lib/silcske/silcske[_status].[ch].
3044 * Resolve the client entry information in the function
3045 silc_client_channel_message to assure that NULL pointer is not
3046 passed as client entry to the application. */
3048 * Fixed the task timeout calculation to assure that there is
3049 never negative timeouts. The affected file is
3050 lib/silcutil/silcschedule.c.
3052 * Fixed the channel user mode notification sending in server.
3053 It was sent point-to-point to the router (or to server by router)
3054 but it needs to be destined to a channel. The routines now
3055 supports sending the channel user mode notifys to the channels
3056 when announcing clients and channels. Affected files are
3057 silcd/server.c and silcd/packet_receive.c.
3059 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3060 It did not actually replace the old channel entry in the cache.
3061 Affected file lib/silcclient/client_notify.c.
3063 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3065 * Fixed a possible crash in silc_packet_send_prepare. It now
3066 assures always that there is enough space in the buffer and
3067 at the tail area of the buffer (for MAC).
3069 Fixed the inbound buffer reallocation in silc_packet_read.
3070 It was old code and did not handle the reallocation correctly.
3073 The affected file is lib/silccore/silcpacket.c.
3075 * Fixed buffer overflow in silc_parse_nickname in the file
3076 lib/silcutil/silcutil.c.
3078 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3080 * make install generates new server keys only if there is not
3083 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3085 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3086 Added check that if the NOREPLY is set then we will not send
3087 the away message. This avoids infinite loop of away messages
3088 if both clients are away. The affected file is
3089 lib/silcclient/client_prvmsg.c.
3091 * Fixed client crash if /NICK was given without arguments.
3092 Affected file lib/silcclient/command.c.
3094 * Server does not send the invite list in INVITE command back
3095 to the client if the list was not altered. Added this notion
3096 to the protocol spec as well. Affected file silcd/command.c.
3098 Fixed possible crash in INVITE command by checking the
3099 value of silc_server_get_client_route command.
3101 * Fixed the INVITE notify type handling. The arguments are now
3102 taken in correct order and client does not crash. The affected
3103 file is irssi/src/silc/core/silc-channels.c.
3105 Removed the "Inviting xxx to channel" message from the
3106 client library away and let the application handle it.
3107 Affected file lib/silcclient/command.c. Added that message
3108 to Irssi SILC client's message formats.
3110 * Fixed CMODE command crash in client. It now checks the
3111 amount of arguments correctly and does not crash. The affected
3112 file is lib/silcclient/command.c.
3114 * Do not create new channel automatically in silc_channels_join
3115 but check whether the channel by that name already exists.
3116 Affected file irssi/silc/core/silc-channels.c.
3118 * Do not send the SERVER_SIGNOFF to router if the disconnected
3119 entity was the router. Affected file silcd/server.c.
3121 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3122 SILC client as it was missing from there.
3124 Added the handling of the KICK notify to the Irssi SILC client
3125 as it was missing. Added "you have been kicked" message to
3126 Irssi SILC client's message modules formats.
3128 Added the handing of the KILL notify to the Irssi SILC client
3129 as it was missing. Added the kill message module formats
3132 The affected file is irssi/src/silc/core/silc-channels.c.
3134 * The router did not save the channel mode the server announced.
3135 Affected file silcd/packet_receive.c.
3137 * Fixed a possible crash in INFO command in server. If the
3138 server did not provide the server info it crashed. Affected
3139 file silcd/command.c.
3141 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3143 * Fixed the GETKEY command in the server to check also the
3144 global list. Otherwise the GETKEY would not work correctly
3145 in normal SILC server. Affected file silcd/command.c.
3147 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3149 * Fixed GETKEY crash, it crashed if the command did not succseed.
3151 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3153 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3154 is now real and not just an macro interface to GMP.
3156 Removed the entire GMP from the source tree and imported new
3157 NSS MPI library instead. Reason for removing GMP is that it is
3158 extremely large and compiles extremely slow. The NSS MPI
3159 is only a few files and compiles in less than 10 seconds.
3160 The speed is also about the same as GMP. The MPI is imported
3161 to lib/silcmath/mpi.
3163 If the system has GMP installed we will still use the GMP.
3164 If it is not then the NSS MPI will be compiled.
3166 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3168 * Merged a long nickname (127 characters long) crash bugfix from
3169 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3171 * Merged a freed memory reference bugfix from Irssi CVS tree.
3172 Affected file irssi/src/core/commands.c.
3174 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3176 * Added the server's public key sving and verification to the
3177 server when performing the SKE. This was missing and the
3178 remote server's (or router's) public key was accepted without
3179 checking whether we have it previously or trust it at all.
3180 Affected file silcd/protocol.c.
3182 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3184 * Check in the silc_server_timeout_remote if protocol is active
3185 and make sure that the protocol's final callback is called so
3186 that all memory if freed. Affected file silcd/server.c.
3188 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3190 * silc_server_whois_send_reply crashed the server if the nickname
3191 was 127 characters long. Affected file silcd/command.c.
3193 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3195 * Added sanity check to the silc_server_new_client. If the hostname
3196 is provided inside username then check that the provided hostname
3197 really is the same as the resolved one. If the hostname was not
3198 resolved then check it from the public key. Affected file is
3199 silcd/packet_receive.c.
3201 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3202 if the server disconnected us and the connection is not valid
3203 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3205 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3206 the library to the lib/silcutil/silcutil.[ch].
3208 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3210 * Close log file after open. Affected file
3211 lib/silcutil/silclog.c.
3213 * Check whether sock == NULL in silc_client_send_packet and return
3214 if it is. Affected file lib/silcclient/silcclient.c.
3216 * Check rec->entry == NULL in the Irssi SILC Client before
3217 sending the channel message. Affecte file is
3218 irssi/src/silc/core/silc-servers.c.
3220 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3222 * Merged a splitted window bugfix from Irssi CVS tree. The
3223 affected file is irssi/src/fe-text/textbuffer-view.c.
3225 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3226 It did not print nickname.
3228 * Improved the distributions system a bit.
3230 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3232 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3233 irssi/src/fe-text/gui-window.c.
3235 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3236 to in-active server. The affected file is
3237 irssi/src/silc/core/client_ops.c.
3239 * Resolve the client in USERS command reply if the entry does
3240 not have username resolved. The affected file is
3241 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3242 command to WHOIS command to really resolve stuff. The USERS
3243 is not used any more in any critical section so WHOIS can
3244 be used even though it might be slower than IDENTIFY.
3246 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3249 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3251 * Changed the protocol API a bit more consistent in the
3252 lib/silccore/silcprotocol.[ch].
3254 * Changed the following headers to ROBODoc format:
3256 lib/silccore/silcpayload.h
3257 lib/silccore/silcprotocol.h
3258 lib/silccore/silcsockconn.h
3260 All core library headers are now formatted.
3262 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3264 * Fixed a bug in Irssi SILC client; do not show that you are
3265 server/router operator if you really are not. Affected file is
3266 irssi/src/silc/core/client_ops.c.
3268 * Renamed silc_command_free_payload to silc_command_payload_free.
3269 Affected file lib/silccore/silccommand.h
3271 * Added silcmath.h to include the prototoypes of various routines
3272 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3275 * Changed the following headers to ROBODoc format:
3277 lib/silccore/silcchannel.h
3278 lib/silccore/silccommand.h
3279 lib/silccore/silcid.h
3280 lib/silccore/silcidcache.h
3281 lib/silccore/silcmode.h
3282 lib/silccore/silcnotify.h
3283 lib/silccore/silcpacket.h
3284 lib/silcmath/silcmath.h
3286 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3288 * Added checking to the server code not to start the server if
3289 ciphers and stuff are not configured properly. Affected files
3290 silcd/serverconfig.[h] and silcd/server.c.
3292 * Changed the layout of the header files of the public interfaces
3293 in the SILC libraries. The new layout supports ROBODoc
3294 documentation tool (and some others) so that it is easy to create
3295 a library reference manual. All the other headers and source
3296 code must still follow the CodingStyle document. Also source
3297 code must not include these ROBODoc stuffs, only the headers.
3298 Furthermore, all public interface headers must now be named
3299 by using `silc' prefix, example: silcapi.h, silccipher.h.
3300 Some files were renamed due to this. All the other headers
3301 must not be used as public interfaces. I will update the
3302 CodingStyle document later. Changed following headers, so far:
3304 lib/silcclient/silcapi.h
3305 lib/silccore/silcauth.h
3306 lib/silccore/silcprivate.h
3307 lib/silccrypt/silcdh.h
3309 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3313 * Removed silc_client_packet_send_flush from the client library
3314 as it is not needed. Affected file lib/silcclient/client.[ch].
3316 * Added printing of message of unresolved authentication method
3317 to the Irssi SILC client. Added it to the module formats.
3318 Removed the same message from the client library.
3320 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3322 * Added new distribution feature, DISTLABEL. Every distribution
3323 can define own preprocessor label that can be used in the
3324 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3325 file distributions, acconfig.h.pre and prepare.
3327 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3329 * Added Makefile.defines_int to include the actual definitions
3330 for Makefile.defines.in. Tested the new distribution system,
3331 created distributions and tested installation.
3333 * Added AWAY message printing to the Irssi SILC client. Added
3334 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3336 * Added SCONNECT command to call the SILC's CONNECT command.
3337 Cannot use CONNECT directly since Irssi uses that internally.
3338 Affected file irssi/src/silc/core/silc-servers.c.
3340 Added ACTION local command. It is same as ME command but takes
3341 the channel as mandatory argument.
3343 Rewrote some of the Irssi's help files to suite for SILC
3346 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3348 * Added Makefile.defines[.in] that should for now on be included
3349 in all Makefile.am file in the source tree. That file includes
3350 all common compilation definitions for SILC source tree.
3352 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3354 * Minor changes to the ./prepare script to change the package
3355 name according the distribution name to the configure.in.
3357 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3359 * Created new distribution system. Added file `distributions'
3360 that defines all the distributions that can be created out of
3361 the SILC source tree. The ./prepare script now reads that
3362 file to determine how to prepare the distributions. The
3363 first argument to the ./prepare is the name of the distribution
3364 and second is the version of the distribution. If given
3365 without arguments it creates the default (toolkit) distribution
3366 with the default version (defined in ./prepare).
3368 All Makefile.am files that are subject to the distributions
3369 are now named as Makefile.am.pre. These are ./Makefile.am
3370 and lib/Makefile.am. Others may be changed later.
3372 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3374 * Added invite list, ban list, some key management and connection
3375 error message printing to module formats in the Irssi SILC client.
3377 * Added new silc_client_set_away_message to set the away message
3378 that is back to the person who sent private message. The
3379 affected file lib/silcclient/silcapi.h and the
3380 lib/silcclient/client_prvmsg.c.
3382 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3384 * Fixed the private message sending in the Irssi SILC client,
3385 added local command KEY to the Irssi SILC client.
3387 Added key management and key agreement message formats to the
3388 irssi/src/fe-common/silc/module-formats.[ch].
3390 Added USERS (alias WHO) printing, server/router operator
3391 indication and LIST command printing to the module formats.
3393 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3395 * Fixed channel joining notify handling, cumode notify handling
3396 from Irssi SILC client.
3398 * Added SILC specific module-formats to the Irssi SILC client so
3399 that SILC specific message hilighting, colors etc is possible.
3400 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3402 Added channel mode, channel user mode, actions, notices,
3403 whois and whowas printing to the the module-formats.c.
3405 * Fixed a bug in channel deletion in the server. The channel
3406 is not left to the cache even if the channel founder auth mode
3407 is set when there are no users anymore on the channel. Affected
3408 file silcd/server.c.
3410 * The silc_net_localhost now resolves the entire hostname including
3411 the domain name. Affected file lib/silcutil/silcnet.c.
3413 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Changed the ask_passphrase client operation to be ascynchronous.
3416 It has now a completion callback and a context that the
3417 application must call after it has got the passphrase from
3418 the user. Affected files lib/silcclient/silcapi.h,
3419 lib/silcclient/protocol.c, lib/silcclient/command.c and
3422 Added SilcAskPassphrase callback that the application calls
3423 to deliver the passphrase to the library.
3425 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3426 The public key verification and especially a certificate
3427 verification is asynchronous procedure.
3429 Added new SILC_SKE_STATUS_PENDING status to indicate the
3430 request is pending and a callback will be called to finalize
3433 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3434 indicate that remote end did not send its public key (or
3435 certificate), even though we require it. Added check for this
3436 condition in the SKE. This was a security bug, now fixed.
3438 Defined new SilcSKEVerifyCbCompletion callback that is called
3439 when the verification process is completed.
3441 The affected files lib/silcske/silcske_status.h and
3442 lib/silcske/silcske.[ch].
3444 * Changed the verify_public_key client operation to be async
3445 as well. Defined SilcVerifyPublicKey callback that is used to
3446 indicate the success of the public key verification process.
3448 Changed the server and client to use the new async client
3451 * Changed the Irssi SILC client's internal scheduler to be called
3452 twice as many times as it used to be. As a result the client
3453 should be a bit faster now. Affected file is
3454 irssi/src/silc/core/silc-core.c.
3456 * Added support to Irssi SILC client of asynchronous public key
3457 verification and passphrase inquiry. Affected file is
3458 irssi/src/silc/core/silc-core.c.
3460 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3462 * Do not say "You have left channel %s" in client library.
3463 Moved it to the application. Affected files are
3464 lib/silcclient/command.c and silc/client_ops.c.
3466 * Fixed silc_client_get_clients. Command context was not
3467 duplicated and was freed memory in the callback. Affected
3468 file lib/silcclient/idlist.c.
3470 * Do not say "you are now talking..." on JOIN command in the
3471 client library. The appliation must handle it.
3473 * Do not say ".. changed topic to" in command reply in the
3474 client libary. The application must handle it.
3476 * Fixed TOPIC command sending in the client library.
3478 * Fixed a memory leak in silc_client_command_free in the file
3479 lib/silcclient/command.c.
3481 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3483 * Imported a modified version of Irssi client to the source tree.
3484 The Irssi will be used to create a new client called
3485 Irssi SILC. Imported to irssi/.
3487 Added silc_core_init_finish function to the Irssi. Affected
3488 file irssi/configure.in.
3490 A lot changes in the Makefile.ams around the irssi tree.
3492 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3494 * Do not rehash if the new size is same as the old size of the
3495 hash table, in the silc_hash_table_rehash*. The affected file
3496 lib/silcutil/silchashtable.c.
3498 * Replaced hash_table_del_by_context calls from the server
3499 (when channel->user_list and client->channels) to the
3500 hash_table_del as it is sufficient and faster.
3502 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3504 * Added silc_hash_table_list, silc_hash_table_get and the
3505 SilcHashTableList structure to provide an alternative way to
3506 traverse the hash table. The affected files are
3507 lib/silcutil/silchashtable.[ch].
3509 * Changed the server's idlist routines to use the hash table
3510 routines to optimize the code.
3512 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3514 * Replaced the client entry's `channel' list and channel entry's
3515 `user_list' list to hash tables for optimized lookup. Changed
3516 the code to use the hash table interface around the code.
3517 Affected file lib/silcd/idlist.[ch].
3519 * Added `auto_rehash' boolean argument to the function
3520 silc_hash_table_alloc to indicate whether the hash table should
3521 auto-rehash when it thinks is appropriate time. It will
3522 increase the hash table size if the there is twice as much
3523 entries in the table than the size of the table, and will
3524 decrease the size if there are twice as less entries than
3525 the size of the table.
3527 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3529 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3531 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3533 * silc_idcache_purge_by_context deletes the entry now by context
3534 as it is supposed to do. Affected file lib/silccore/idcache.c.
3536 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3537 client is not anymore valid (WHOWAS givens the info) and not
3538 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3540 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Removed the `data' and `data_len' arguments from the ID Cache
3543 interfaces and added `name' argument. ID Cache does not handle
3544 anymore the binary data only a names associated with given ID.
3546 * When hashing a Client ID with silc_hash_id the entire ID is
3547 not hashed anymore, instead only the hash of the Client ID is
3548 hashed. This way we can access the Client ID from the cache
3549 with Client ID but with the hash of the ID (which is a hash of
3550 the nickname) as well without any difference in performance.
3552 Added also silc_idcache_find_by_id_one_ext to do one on one
3553 searching when we have the actual ID. Added also function
3554 silc_hash_client_id_compare. The affected files are
3555 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3557 * When hashing the name associated with a ID it is always done
3558 in lowercase. This way we can access the cache without worrying
3559 about case-sensitivity, even though, for example nicknames are
3562 * Fixed a bug in server with channel message sending. It put
3563 wrong ID type as destination ID. The affected file
3564 silcd/packet_send.c.
3566 * silc_idcache_del_by_context now deletes from all hash tables
3567 by context. Affected file lib/silccore/idcache.c.
3569 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3571 * Changed the client library to use the new ID Cache interface.
3572 Changes around the source tree.
3574 * Added silc_hash_table_rehash_ext to rehash with specific
3575 hash function. Affected file lib/silcutil/silchashtable.[ch].
3577 * Added silc_hash_string_compare to compare two strings in the
3578 hash table. Affected file lib/silcutil/silcutil.[ch].
3580 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3582 * Added new function silc_idcache_del_by_context into the
3583 lib/silccore/idcache.[ch].
3585 * Changed the server's ID list routines to use the new ID Cache
3586 interface. Changes around the source tree.
3588 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3590 * Added silc_hash_table_del[_by_context]_ext functions in to the
3591 lib/silcutil/silchashtable.[ch].
3593 Removed silc_hash_table_find_all* routines and added new
3594 silc_hash_table_find_foreach to replace them.
3596 Added silc_hash_table_replace_ext function as extended
3597 replacing function. Separated the simple hash table interface
3598 from the extended hash table interface in the file
3599 lib/silcutil/silchashtable.h.
3601 * Fixed minor bugs and changed it to use some of the new
3602 hash table functions in lib/silccore/idcache.c
3604 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3606 * Added new function silc_hash_table_find_all to return all keys
3607 in the hash table by the specified key. As the hash table is
3608 collision resistant it also makes it possible to have several
3609 duplicate keys in the hash table. This function may be used to
3610 find all of the keys from the hash.
3612 Added user_context arguments to the SilcHashFunction,
3613 SilcHashCompare and SilcHashDestructor to deliver user specified
3616 Added new fuctions silc_hash_table_find[_all]_ext to do
3617 extended lookup with specified hash and compare functions and
3618 specified user contexts.
3620 Added new function silc_hash_table_add_ext to add the key
3621 with specified hash function and user context.
3623 Added new function silc_hash_table_foreach to traverse all
3624 entrys in the hash table. Added SilcHashForeach callback
3627 Added new function silc_hash_table_del_by_context to delete
3628 the entry only if the context associated with the key matches.
3630 Affected files are lib/silcutil/silchashtable.[ch].
3632 * Removed silc_hash_[server/client/channel]_id and added just
3633 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3634 silc_hash_id_compare to compare two ID's using as the hash table
3635 comparison function. Added also silc_hash_data to hash
3636 binary data and silc_hash_data_compare to compare it.
3638 * Removed silc_idlist_find_client_by_hash as it is not needed
3639 anymore. Affected file silcd/idlist.[ch].
3641 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3642 to use internally the SilcHashTable. The new ID Cache is a lot
3643 faster than the old one. Some of the ID Cache interface was also
3644 rewritten and obsolete and stupid functions were removed.
3646 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * Added entry_count field to the SilcHashTable to keep the number
3649 of the entries in the table. Implemented the function
3650 silc_hash_table_rehash. Added new function
3651 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3653 Fixed a minor bug in silc_hash_table_free.
3655 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3656 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3657 into the lib/silcutil/silcutil.[ch].
3659 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3661 * Implemented a collision resistant hash table into the
3662 lib/silcutil/silchashtable[ch]. See the header and the source
3663 for the SilcHashTable API.
3665 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3667 * Merged dotconf version 1.0.2 into lib/dotconf.
3669 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3671 * Do not compile anything in lib/silcsim/* if the SIM support
3672 is not enabled. The tree should now compile without problems
3675 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3677 * Compiled the SILC under cygwin. Compiled and tested briefly
3678 without problems. More tests needed. The SIMs didn't compile
3681 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3683 * Fixed possible crash in silc_get_username in the
3684 lib/silcutil/silcutil.c.
3686 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3688 * Fixed a va_arg in silc/client_ops.c.
3690 * Oops, RC5 routines were named AES and caused some problems
3691 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3693 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3695 * Added new SilcIDIP structure into the lib/silccore/id.h and
3696 replaced the old `ip' fields from all SILC ID's to that type.
3697 This is a step towards IPv6 support.
3699 The silc_id_get_len takes now the ID as an extra argument.
3700 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3701 both IPv4 and IPv6 based ID's.
3703 The affected files are lib/silccore/id.[ch] and other files
3704 around the tree using these routines.
3706 * Removed the ID length arguments in server from various
3707 silc_server_send_notify_* routines -> they are not needed
3710 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3712 * Fixed memory leak in silc_encode_pem_file in the file
3713 lib/silcutil/silcutil.c.
3715 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3717 * Check minor version as well in the SKE. Affected files are
3718 silcd/protocol.c and lib/silcclient/protocol.c.
3720 * Added --identifier option to the server so that an identifier
3721 can be when creating the public key for the server. Affected
3722 file is silcd/silcd.c.
3724 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3725 lib/silccrypt/silcpkcs.c.
3727 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3729 * Register default ciphers and stuff when using -C option with
3730 the server. Affected file sildc/silcd.c.
3732 * Put back the servers public key filename format, it is better
3733 than the new one. For now, the client keys are saved with the
3734 new filename format. The affected file silc/client_ops.c.
3736 * Implemented the Cipher API for the rest of the ciphers that
3737 did not implement it or implemented it the wrong way.
3739 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3741 * Register default ciphers and stuff when using the -S option
3742 in the client. Affected file silc/silc.c. Same also when
3743 creating new key pair with -C option.
3745 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3747 * Fixed the silc_verify_public_key client operation function to
3748 save the public keys differently. The fingerprint is now
3749 used as filename and not the hostname. This way also the
3750 client keys are saved uniquely and not with hostnames. The
3751 affected file is silc/client_ops.c.
3753 * Trimmed the silc_hash_fingerprint function to remove extra
3754 whitespaces from the end of the fingerprint. The affected
3755 file is lib/silccrypt/silchash.c.
3759 * Added silc_cipher_register_default function to register all
3760 default ciphers. It can be used when configuration files
3761 does not exist and the application does not want any specific
3762 ciphers in any specific order.
3764 The SilcDList is now used as silc_cipher_list dynamically
3765 allocated cipher list. Removed the static list all together
3766 and now all ciphers must be allocated to the dynamic list.
3767 The silc_cipher_alloc routine was changed to check only the
3770 All silc_cipher_* routines that used to return int returns
3773 The affected files lib/silccrypt/silccrypt.[ch].
3775 * The same thing was done to silc_hash_* as for silc_cipher_*
3776 routines. Affected files lib/silccrypt/silchash.[ch].
3778 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3779 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3780 Added also silc_pkcs_[un]register[_default] functions.
3781 Removed the data_context from the PKCS API.
3783 * Added silc_hmac_register_default function to register default
3784 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3785 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3786 to unregister all hmacs at once.
3788 * Register the default ciphers, hash functions, PKCSs and HMACs
3789 if client's configuration file does not exist. The affected
3792 * The client did not load the hash functions from the SIM
3793 modules at all. Added support for this. Affected file is
3794 silc/clientconfig.c.
3796 * When decoding public key with silc_pkcs_public_key_decode, check
3797 the supported algorithm only if PKCS are registered. Affected
3798 file lib/silccrypt/silcpkcs.c. The same was done with the
3799 silc_pkcs_private_key_decode.
3801 * Fixed the SILC List routines to keep the list always in order.
3802 It used to change the list's order when traversing the list but
3803 not it preserves the order. Affected file lib/trq/silclist.h.
3805 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3807 * Added the client library to use the SilcSocketConnection's
3808 reference counter (by silc_socket_dup) to prevent the bug that
3809 the socket object may be freed underneath async operation.
3811 * The name resolv library checking fixes in the configure.in.pre.
3814 * Created new version of the protocol drafts for future
3815 development. The -03 drafts are the ones that will be changed
3816 in the trunk now and the -02 will remain as they are.
3818 * Send list of CUMODE notifys to the router when announcing
3819 the channel users to the router. Affected file silcd/server.c.
3820 If the router receiving channel founder CUMODE for a channel
3821 that already has channel founder it will send CUMODE notify
3822 to the sender to remove the channel founder rights from the
3823 announced client. Affected file silcd/packet_receive.c.
3825 * The CUMODE notify may now use Server ID as well as the entity
3826 who changes the mode. Updated protocool specs.
3828 * Updated INSTALL and README files.
3830 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3832 * New web pages in the http://silc.pspt.fi. The pages was
3837 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3839 * Implemented the [DenyConnectin] config section in the server.
3840 Added silc_server_config_denied_conn to check whether incoming
3841 connection is denied. Affected file silcd/serverconfig.[ch].
3843 * Do not check the ports when checking the incoming configuration
3844 data if the port is 0, meaning any. Affected file is
3845 silcd/serverconfig.c.
3847 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3849 * Fixed buffer overflow in silc_string_compare in the file
3850 lib/silcutil/silcutil.c.
3852 * Fixed double free in silc_server_command_leave in the file
3855 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3857 * Fixed the version checking in the server. Affected file is
3860 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3862 * Fixed the configuration data fetching when accepting new
3863 connections in the server. Affected file silcd/server.c.
3865 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Added `sender_entry' argument to the function
3868 silc_server_packet_relay_to_channel so that we can check
3869 whether some destination actually belongs to the same route
3870 the sender belongs (ie, we must not resend the packet to the
3871 sender). Affected file silcd/packet_send.[ch].
3873 * Added `servername' field to the SilcClientEntry in the server
3874 to hold the name of the server where client is from. Affected
3875 file is silcd/idlist.h.
3877 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3879 * Moved the channel message encrypting in the router betwen
3880 router connections from silc_server_channel_message to the
3881 silc_server_packet_relay_to_channel since we want to check
3882 whether we have anybody channel before encrypting anything.
3883 Affected files silcd/packet_[receive/send].c.
3885 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3887 * Fixed the [AdminConnection] server config section to support
3888 multiple entries. Affected file silcd/serverconfig.c.
3890 * Added support into the server to check the validity of the
3891 incoming connection before executing any KE or authentication
3894 * The connection configuration is now saved to the KE and
3895 connection auth protocol contexts and not fetched anymore in
3896 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3898 * The local hosts listenning address and port is also resolved
3899 now when starting the server. We want to have the socket object
3900 to include the real address and port for the listener. Added
3901 new function silc_net_check_local_by_sock into the files
3902 lib/silcutil/silcnet.[ch].
3904 * Fixed a broadcast bug in server -> do not broadcast if we
3907 * Fixed a routing bug. Do not route broadcast packets ever.
3908 Broadcast packets must be processed always and not routed since
3909 they may be destined to some other host than yourself and thus
3910 would get routed without no good reason. Affected file is
3913 * Added function silc_server_config_is_primary_route to check
3914 whether primary router connection has been configured (a router
3915 configuration that we are initiating). If there is not, we
3916 will assume that there is only two routers in the SILC network
3917 and we will use the incoming router connection as our primary
3918 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3920 * Changed the order of the broadcasting. Broadcast _after_ the
3921 packet has been processed not before. Affected file is
3924 * Fixed a [ClientConnection] parsing bug. The port was never
3925 parsed correctly thus resulting to port 0. Affected file
3926 silcd/serverconfig.c.
3928 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3929 argument and did not set the broadcast packet flag. Affected
3930 file silcd/packet_send.c. Fixed same bug in the function
3931 silc_server_send_notify as well.
3933 * If we receive NEW_ID packet for our own ID in the server, ignore
3936 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Removed the nickname from the Private Message Payload.
3941 Updated the code and the protocol specs.
3943 * Updated protocol specs for submitting to the IETF.
3945 * Tweaked the Random Number Generator a bit. Affected file
3946 lib/silccrypt/silcrng.c. Exported a new function
3947 silc_rng_[global]_add_noise which can be used to add more
3950 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * Do not parse packets with different timeout when protocol
3953 is active -> may cause problem with rekey. Affected file
3956 * When server receives signoff notify it must not create
3957 new channel key if the client is on any channels since the
3958 sender of the signoff notify will create it.
3960 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3962 * Added printing of error messages during SKE protocol from the
3963 failure packet sent by server during SKE. Affected file
3966 * Removed the client's failure_callback handling with timeout
3967 and handle it immediately when received.
3969 * The SKE library returned wrong type in SUCCESS and FAILURE
3970 packets. They must be 32 bit MSB not 16 bit MSB.
3972 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3974 * Ok, rewrote the logic of the re-key and now it seems to work.
3975 I tested it on high traffic with frequent re-keys without
3976 problems. Added hmac_receive (and renamed hmac to hmac_send)
3977 in SilcClientConnection in lib/silcclient/client.h and
3978 in SilcIDListData in silcd/idlist.h. Also, removed the
3979 SilcPacketParserContext's cipher and hmac fields as they are
3980 not needed anymore and actually caused some problems when
3981 the ciphers and hmac's changed underneath the packet parser.
3983 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * If re-key protocol is active then process the incoming packets
3986 synchronously since we must assure that icoming packets encrypted
3987 with the old key is processed before the new keys is set to
3988 use. This is true other packets than for REKEY packets.
3989 Affected file silcd/server.c. The same was done to client library
3990 as well, affected file lib/silcclient/client.c.
3992 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3994 * Fixed bug in client and server to accept the force send if
3995 the packet is send from silc_[server/client]_packet_process
3996 function. Otherwise the packets are never delivered, oops.
3998 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4000 * Disable force sending of packets when REKEY protocol is active.
4001 We must assure that no packet is sent directly when rekey is
4002 performed. All packets must be sent through packet queue.
4003 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4004 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4005 function is silc_[server/client]_packet_send_real to check
4008 * Replaced the SIM paths from example config files to
4009 /usr/local/modules. Also, make install creates now
4010 /usr/local/silc/logs directory to hold all the SILC server
4013 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * Made the configure.in.pre work on Solaris. Patch by salo.
4017 * Made all ciphers compatible with non-x86 machines. Defined
4018 CBC mode macros into lib/silccrypt/ciphers_def.h.
4020 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4022 * Fixed the make install.
4024 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4026 * When MAC computation fails the silc_packet_decrypt returned 0
4027 even though it was supposed to return -1. Fixed this. The
4028 affected file is lib/silccore/silcpacket.c.
4030 * Do not replace the config files in /etc/silc (in make install)
4031 if they already exist. Affected file ./Makefile.am.
4033 * Do not send re-key packets immediately but through packet queue.
4034 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4036 * Changed silc_net_check_host_by_sock to return FALSE if the
4037 IP/DNS could not be resolved. Though, it returns the IP address
4038 now even if it could not resolve it (but returns also FALSE).
4039 Affected file lib/silcutil/silcnet.[ch].
4041 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4043 * Added silc_pkcs_decode_identifier to decode the public key's
4044 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4045 Added also silc_pkcs_free_identifier. Added also new context
4046 SilcPublicKeyIdentifier.
4048 * Added -S option to the silc client. It is used to dump the
4049 contents of the specified public key file.
4051 * Changed the PKCS api to return the public key length when
4052 setting the public key.
4054 * Fixed a fatal bug in the public and private key file loading.
4055 Affected file lib/silccrypt/silcpkcs.c.
4057 * Execute the packet parsing for client with zero (0) timeout
4058 if the protocol is active. Affected file silcd/server.c.
4060 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4062 * Made the key generation options to the silcd program. Added
4063 -C option, equivalent to client's option.
4065 * Added new [ServerKeys] config section to the server. It
4066 configures the server's public and private key.
4068 * Defined generic Public Key Payload into the protocol
4069 specification to send specific type of public keys and
4072 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4073 public key or certificate.
4075 * Implemented the GETKEY command to the server and to the
4076 client library and on user interface.
4078 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4080 * Made preliminary `make install' work.
4082 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * Added SilcServerRekey context into silcd/idlist.h.
4086 * Added the PFS support as defined in the specification to the
4087 SKE protocol. Affected files lib/silcske/*.c.
4089 * Added `ske_group' field to the SilcServerRekey context to hold
4090 the number of the SKE group that is used with PFS in re-key.
4091 Affected file silcd/idlist.h.
4093 * Added PFS re-key support to the server. Affected file is
4096 * Added silc_protocol_cancel to cancel execution of the next
4097 state of the protocol. Affected file is
4098 lib/silccore/silcprotocol.[ch].
4100 * Added the re-key support with and without PFS to the client
4101 library. Re-key is performed once in an hour, by default.
4103 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4104 Added silc_client_rekey_callback and silc_client_rekey_final.
4105 Affected files are lib/silcclient/protocol.[ch] and
4106 lib/silcclient/client.[ch].
4108 * Removed the `hmac_key' and `hmac_key_len' fields from the
4109 SilcClientConnection structure; not needed. Affected file is
4110 lib/silcclient/client.h.
4114 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4116 * Do not ask whether user wants to use the negotiated private key
4117 for private messages, just use it. Affected file is
4118 silc/local_command.c.
4120 * Added `send_enc_key' and `enc_key_len' fields to the
4121 SilcIDListData structure since they are needed in the re-key
4122 phase. Affected file is silcd/idlist.[ch].
4124 * Implemented the simple re-key protocol into the server.
4125 Affected files silcd/server.c and silcd/protocol.[ch]. The
4126 re-key will be performed once in an hour, by default.
4128 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4129 Added silc_server_rekey, silc_server_rekey_callback and
4130 silc_server_rekey_final.
4132 * Removed Tunneled flag from the protocol. Updated the code
4133 and the specifications.
4135 * Adde `pfs' field to the SilcIDListData to indicate whether
4136 the PFS is to be performed in the re-key. Affected file is
4139 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4141 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4142 int64 of at least the xintXX size. If void * is less that 4
4143 bytes uint32 * will be used. Defined bool as boolean.
4145 * Changed _ALL_ unsigned long and unsigned int to uint32,
4146 unsgined short to uint16 in the source tree.
4148 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4149 not handle clients that has entry->data.registered == FALSE.
4150 They are not in the network anymore. Affected file is
4153 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4155 * Implemented the sending of the SERVER_SIGNOFF notify in the
4156 server. Affected file is silcd/server.c.
4158 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4159 Added also silc_notify_payload_encode_args into the
4160 lib/silccore/silcnotify.[ch].
4162 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4163 Affected file silcd/packet_receive.c.
4165 * Implemented the SERVER_SIGNOFF notify handling in the client
4166 library. Affected file lib/silcclient/client_notify.c. Also,
4167 implemnted the printing of the SERVER_SIGNOFF info to the
4168 application. Affected file silc/client_ops.c.
4170 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4171 if the deleting was successful. Affected file silcd/idlist.[ch].
4173 * Added support for public key authentication in the connection
4174 authentication protocol in the client library. Affected file
4175 lib/silcclient/protocol.c.
4177 * Changed the server's silc_idlist_get_clients_by_* interface
4178 to support already allocated array so that new entries may be
4179 added to pre-allocated array. Affected file silcd/idlist.[ch].
4180 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4181 and command replies.
4183 * All command reply functions in the server now calls the
4184 pending command callback even if error occured. This way the
4185 error will be delivered to the client as well. Affected files
4186 silcd/command.c and silcd/command_reply.c.
4188 * Fixed INFO command to return local server's info if no server
4189 was provided. Affected file lib/silcclient/command.c.
4191 * Removed RESTART command for good. Updated the code and the
4194 * Rewrote parts of the task system. It is a bit simpler now.
4195 Removed unsued task priorities. The affected files are
4196 lib/silcutil/silctask.[ch].
4198 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4200 * Moved the USERS printing from the library to the application.
4201 Affected files lib/silcclient/command.c and silc/client_ops.c.
4203 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * Added channel key re-key support. The re-key is perfomed
4208 only by the router and is done once in an hour. Added `rekey'
4209 field to the SilcChannelEntry in the server. Affected files
4210 silcd/server.c and silcd/idlist.h.
4212 * Added silc_task_unregister_by_context into the file
4213 lib/silcutil/silctask.[ch].
4215 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Added SILC_UMODE_GONE mode to indicate when the client is not
4218 present in the SILC network. Added also support to the local
4219 command AWAY that will set this mode. Added support of showing
4220 "xxx is gone" in WHOIS command. The USERS command shows the
4221 gone status as well.
4223 * Fixed setting server and router operator privileges in the
4224 server's UMODE command. Affected file silcd/command.c.
4226 * Merged the SKE KE1 and KE2 payloads into one payload. The
4227 new KE payload is equivalent to the old KE2 payload.
4229 Cleaned up the SKE Start Payload parsing. It now uses the
4230 simple buffer unformatting to do the parsing. A lot faster
4233 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4234 to the SKE that is used to indicate whether both of the SKE
4235 parties should perform authentication. By default only the
4236 responder performs authentication. By setting this flag also
4237 the initiator must do authentication. By default it is unset
4238 since in normal SKE case, client to server connection, only
4239 the responder should do authentication. When doing SKE between
4240 two clients both should perform authentication. Updated the
4241 code and the protocol specs.
4243 * A little fix to IDENTIFY command in the server. Search the
4244 client first by hash not nickname. Affected file is
4247 * Fixed the silc_client_close_connection to support closing
4248 the client to client connections wihtout deleting too much
4249 data. Affected file lib/silcclient/client.c.
4251 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4252 are received if protocol used to be active but is not anymore
4253 the application would crash due to NULL pointer dereference.
4254 Affected files silcd/server.c and lib/silcclient/client.c.
4256 * Added `hash' field to the SilcClientConnection to include
4257 the hash function negotiated in the SKE protocol.
4259 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4260 to set the channel founder authentication data. A client can
4261 claim the founder rights later by providing the authentication
4262 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4263 This way the channel founder can regain the channel founder
4264 privileges even it is left the channel. This works only on
4265 local server and the client must be connected to the same
4266 server to be able to regain the founder rights. Updated the
4267 protocol specs accordingly.
4269 Added support to the CMODE command in the client to set the
4270 founder auth data. Read the README to see how to set it.
4272 Added support to the CUMODE command to claim the founder
4273 rights. Read the README to see how to do it.
4275 Added support for the founder authentication to the Channel
4276 Entry in the server. Affected file silcd/idlist.h.
4278 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4279 server's CMODE command. Affected file silcd/command.c.
4281 * Added the following new functions into lib/silccore/silcauth.[ch]:
4282 silc_auth_get_method and silc_auth_get_data.
4284 * The server now saves the remote hosts public key to the
4285 SilcIDListData pointer. Affected file silcd/protocol.c.
4287 * The normal server now does not remove the channel entry from
4288 the cache if the founder authentication data is set. It used
4289 to remove it if the founder was the last one on the channel on
4290 the server and left the channel. The auth data is saved and
4291 if the channel is re-joined later the old entry is used with
4292 the old auth data. Affected files silcd/command_reply.c and
4295 * Removed the `pkcs' field from the SilcIDListData structure
4296 in the server; it is not used. Affected file silcd/idlist.h.
4298 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4300 * Fixed packet processing on slow links. Partial packets were
4301 never re-processed because the incoming data buffer was cleared
4302 by the application. Application must not directly clear the
4303 sock->inbuf, the packet processing routines handle it. Fixed
4304 this in client library and in server.
4306 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4308 * Fixed the WHOIS and IDENTIFY send reply function to really
4309 check whether to send list or just one entry. Affected file
4312 * Cleaned up the LEAVE command's channel key distribution. The
4313 affected file silcd/command.c.
4315 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4316 can enforce the channel mode as well. In that case the ID
4317 includes the ID of the server. The code now enforces the
4318 mode change if the router have different mode than the server.
4320 * The notify client operation with CMODE_CHANGE notify can now
4321 return NULL client_entry pointer if the CMODE was not changed
4322 by client. Application must check for this.
4324 * Added <Server ID> argument to INFO command to support server
4325 info fetching by Server ID.
4327 * Added silc_server_announce_get_channel_users to get assembled
4328 packets of channel users of the specified channel. Affected
4329 file silcd/server.[ch].
4331 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4332 was freed underneath the ID Cache.
4334 * Re-announce clients when the server received CHANNEL_CHANGE
4335 notify from the router. Affected file silcd/packet_send.c.
4337 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4339 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4340 crashed since it did not handle the fact that there is no cipher
4341 called "3" and didn't check the error condition. Now fixed.
4343 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4344 flag. It can be used to send message requests.
4346 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4348 * Implemented the RESTART command in the client.
4350 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4351 notice type messages. Added notice printing to the user
4354 * The channel keys are not re-generated if the channel's mode
4355 is PRIVKEY, ie private key on the channel exists. Affected
4356 files silcd/server.c and silcd/command.c.
4358 * Fixed a little bug in channel message delivery when channel
4359 private keys are set in the server. Affected file is
4360 silcd/packet_send.c.
4362 * Changed the setting on channel->on_channel = TRUE from the
4363 silc_client_save_channel_key to the JOIN command reply. The
4364 key payload is not received if the private channel key is set.
4365 Affected file lib/silcclient/command_reply.c and the
4366 lib/silcclient/client_channel.c.
4368 * When the CMODE_CHANGE notify is sent and the channel private
4369 key mode is removed the channel key must be re-generated in
4370 other cells as well. Added this support for the router in the
4371 silcd/packet_receive.c.
4373 * Added new local command NOTICE to send notice message on
4374 channel. Affected file silc/local_command.[ch].
4376 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4378 * Added new local command ME to the client. It is used to send
4379 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4380 some action. Affected file silc/local_command.[ch].
4382 * Changed channel_message and private_message client operations
4383 to deliver the message flags to the application. Added also
4384 the `flags' arguments to the silc_client_send_channel_message
4385 and silc_client_send_private_message functions. Affected file
4388 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4390 * Redefined the Private Message Payload to support private message
4391 keys and to support the new private message flags. Updated
4392 the protocol specs. Flags makes it possible to have for example
4393 CTCP style messages.
4395 * Added new type SilcPrivateMessagePayload and defined an API
4396 for it in the lib/silcclient/silcprivate.[ch].
4398 * Tested private message private keys successfully. Tested the
4399 private message key set, unset and list commands with the new
4402 * Redefined the Channel Message Payload to include the channel
4403 message flags (equal with private message flags) to support
4404 for example CTCP style messages.
4406 * Defined some of the message (for channel and private message)
4407 flags. Updated the protocol specs and added the flags to the
4408 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4410 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4412 * Added SilcKeyAgreementStatus type to the key agreement routines
4413 to indicate the current status and error if one occured.
4414 The status types are defined in the lib/silcclient/silcapi.h.
4416 * Added new local command KEY that is used to set and unset private
4417 keys for channels, set and unset private keys for private messages
4418 with remote clients and to send key agreement requests and
4419 negotiate the key agreement protocol with remote client. The
4420 key agreement is supported only to negotiate private message keys,
4421 it currently cannot be used to negotiate private keys for channels,
4422 as it is not convenient for that purpose.
4424 * Fixed a minor pending callback setting bug in the function
4425 silc_client_get_client_by_id_resolve, now the function works.
4426 Affected file lib/silcclient/idlist.c.
4428 * Added function silc_net_get_local_port to get local bound
4429 port by socket. Added to lib/silcutil/silcnet.[ch].
4431 * Added `sockets' and `sockets_count' fields to the SilcClient
4432 object. They hold the sockets of the listenning sockets in
4433 the client. Listenning sockets may be for example the key
4434 agreement server. Affected file lib/silcclient/client.[ch].
4435 Added functions the silc_client_add_socket and the
4436 silc_client_del_socket. They are exported to the application
4439 * Added ~./silc/clientkeys to support other client's public keys.
4441 * Renamed verify_server_key client operation to verify_public_key
4442 and added one argument to indicate the type of the connection
4443 (server, client etc.).
4445 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4447 * Added silc_server_connection_auth_request to handle the
4448 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4449 silcd/packet_receive.[ch].
4451 * Added silc_server_send_connection_auth_request into the
4452 silcd/packet_send.c to send the connection auth request packet.
4454 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4457 * Fixed the public key authentication in responder side in the
4458 server. The `auth_data' pointer includes the SilcPublicKey
4459 not the path to the public key. Affected file silcd/protocol.c.
4461 * Implemented the public key authentication in the initiator side
4462 in the server. Affected file silcd/protocol.c.
4464 * Removed the [RedirectClient] config section from the server
4465 configuration. Is not needed and I don't want to implement it.
4467 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4469 * Cleaned up the CMODE command in the server. It now works
4470 correctly and supports all the modes defined in the protocol.
4471 Affected file is silcd/command.c.
4473 * Added `hmac_name' field to the SilcChannelEntry in the server
4474 to hold the default HMAC of the channel. It can be set when
4475 creating the channel (with JOIN command). Affected files
4478 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4479 type to indicate the change of the current cipher and hmac
4480 on the channel. Client can safely ignore the <cipher> argument
4481 (if it chooses to do so) since the CHANNEL_KEY packet will
4482 force the channel key change anyway. The <hmac> argument is
4483 important since the client is responsible of setting the new
4484 HMAC and the hmac key into use.
4486 * Fixed the CMODE command in the client library as well.
4488 * Tested CMODE command in router environment successfully.
4490 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4492 * Show the version of the remote client (or server) when connecting
4493 to the server. It is logged to the log file. Affected file
4494 is silcd/protocol.c.
4496 * Fixed the KILLED notify handling in the client library. The
4497 client must be removed from all channels when receiving the
4500 Also, do not remove the client entry when giving the KILL
4501 command but when the KILLED notify is received.
4503 * Removed silc_idlist_find_client_by_nickname from the server.
4504 Not needed anymore. Affected files silcd/idlist.[ch].
4506 * Implemented the CHANNEL_CHANGE notify type handling to the
4507 server. Affected file silcd/server.c.
4511 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4513 * Added silc_server_send_notify_invite to send the INVITE
4514 notify between routers.
4516 * Implemented the INVITE command correctly to the server.
4518 * Implemented the INVITE notify type handling in the server.
4520 * Implemented the INVITE command to the client library and on the
4523 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4525 * Added function silc_server_get_client_resolve to find the
4526 client entry by ID from all ID lists and then resolve it
4527 (using WHOIS) if it cannot be found. Affected file is
4530 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Implemented the BAN command to the client library.
4534 * The JOIN command in the server now checks the invite list
4537 * Changed the silc_command_reply_payload_encode_va and the
4538 silc_command_payload_encode_va to support that if argument is
4539 NULL it ignores and checks the next argument. Affected file
4540 lib/silccore/silccommand.c.
4542 * Added silc_server_send_notify_ban to send the BAN notify
4543 type between routers.
4545 * Chaned the silc_notify_payload_encode to support that if
4546 argument is NULL it ignores and checks the next argument.
4547 Affected file lib/silccore/silcnotify.c.
4549 * Tested ban lists in router environment successfully.
4551 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4553 * Implemented BAN command to the server, in silcd/command.[ch].
4555 * Removed the BAN and INVITE_LIST modes from the CMODE command
4558 * Added function silc_string_match to regex match two strings.
4559 Affected files lib/silcutil/silcutil.[ch].
4561 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4563 * Redefined parts of the SilcChannelEntry in the server to support
4564 the new ban and invite lists.
4566 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4568 * Redefined the INVITE command. The same command can be used to
4569 invite individuals to the channel but also to manage the invite
4570 list of the channel (to add to and remove from the invite list).
4571 Updated the protocol specs.
4573 * Added new command SILC_COMMAND_BAN that can be used to manage
4574 the ban list of the channel. Updated the protocol specs.
4576 * Removed the channel modes: the SILC_CMODE_BAN and the
4577 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4578 in the CMODE command. The equivalent features are now available
4579 using INVITE and BAN commands. Updated the protocol specs.
4581 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4582 in the network about change in the current ban list. The notify
4583 type is not used by the client.
4585 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4586 support the invite lists.
4588 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Added new function silc_string_regexify that converts string
4591 including wildcard characters into regex string that can
4592 be used by the GNU regex library. Added into the file
4593 lib/silcutil/silcutil.[ch].
4595 Added silc_string_regex_combine to combine to regex strings
4596 into one so that they can be used as one regex string by
4597 the GNU regex library. Added into the file
4598 lib/silcutil/silcutil.[ch].
4600 Added silc_string_regex_match to match two strings. It returns
4601 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4603 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * Imported GNU regex to the soruce tree into lib/contrib.
4606 Fixed some compiler warning from the regex.c.
4608 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4610 * Fixed MOTD command in the server to work in router environment.
4612 * Fixed the MOTD command in the client library to support
4613 the server argument in the command.
4615 * Added `nickname_len' argument to the silc_idlist_add_client
4616 in the server, as the `nickname' argument may be binary data
4619 * Added silc_idlist_get_channels to return all channels from
4622 * Implemented LIST command to the server. Affected file is
4625 * Implemented the LIST command to the client library and on the
4628 * Added [<user count>] argument to the LIST command reply.
4629 With private channels the user count is not shown.
4631 * Updated TODO and README.
4633 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4635 * The client entry's data.registered must be TRUE even with
4636 global client entry on global client list. The data.registered
4637 is used to check whether the client is anymore in the network,
4638 for example with WHOWAS command so it must be valid.
4640 * Fixed the WHOWAS command in the server. It now actually works
4641 in router environment. Added function into silcd/command_reply.c
4642 silc_server_command_reply_whowas_save.
4644 * Added silc_idlist_purge function to the silcd/idlist.c
4645 to periodically purge the ID Cache.
4647 * Fixed INFO command in the server. It works now in router
4648 environment. Added <server name> argument to the INFO command
4649 reply. Updated the protocol specs.
4651 * Fixed minor bug in silc_idcache_purge to not purge if the
4652 expire value is zero.
4654 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4655 they were buggy because of the WHOWAS information.
4657 * Fixed local command MSG to handle the async resolving of
4658 the remote client properly. It used to fail the first MSG.
4659 Affected file silc/local_command.c.
4661 * Added `data_len' field to SilcIDCache context.
4663 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4665 * Update TODO. Todo in commands in the server.
4667 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4669 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4670 used by routers as broadcast packet to inform other routers
4671 about the changed user mode.
4673 Implemented the notify handling in the server. Affected file is
4674 silcd/packet_receive.c. Added the function
4675 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4677 * Added new generic Channel Payload and deprecated the New Channel
4678 Payload. The New Channel Payload is now the generic Channel
4681 * Added new argument `mode' to the silc_server_send_new_channel
4682 as it is required in the Channel Payload now.
4684 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4685 and created a new and real SilChannelPayload to represent the
4686 new generic Channel Payload. Implemented the encode/decode
4687 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4689 * Added silc_server_get_client_channel_list to return the list
4690 of channels the client has joined for WHOIS command reply.
4691 Affected file silcd/server.[ch].
4693 * Implemented the channel list sending in the WHOIS command reply
4694 in server and in the client.
4696 Implemented the channel list displaying on the user interface
4697 as well. Affected file silc/client_ops.c.
4699 * Added silc_channel_payload_parse_list to parse list of Channel
4700 Payloads. It returns SilcDList list of SilcChannelPayloads.
4701 Client for example can use this function to parse the list of
4702 channels it receives in the WHOIS command reply. The caller
4703 must free the list by calling silc_channel_payload_list_free.
4704 Affected files lib/silccore/silcchannel.[ch].
4706 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4708 * Added one new argument <user mode> to the WHOIS command reply
4709 to return the mode of the user in SILC. Updated the protocol
4712 Implemented it to the server and client.
4714 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4716 * Fixed the mode printing on the user interface on joining.
4717 Affected file silc/client_ops.c.
4719 * Implemented the UMODE command and user modes in general to the
4720 client library and to the user interface.
4722 * Implemented the UMODE command to the server.
4724 * The server now sends UNKNOWN_COMMAND error status if client sends
4725 unknown command. Affected file silcd/command.c.
4727 * All server commands now handle the command identifier the right
4728 way when sending the command reply to the client. The client can
4729 use to identify the command replies with the identifier.
4731 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4733 * Added silc_server_get_client_route to resolve the route to
4734 the client indicated by the client ID. Affected file is
4737 * Added silc_server_relay_packet as general function to relay
4738 packet to arbitrary destination. This deprecates functions
4739 like _send_private_message_key, _relay_notify etc. Affected
4740 file is silcd/packet_send.[ch].
4742 Removed silc_server_send_key_agreement,
4743 silc_server_send_private_message_key and
4744 silc_server_packet_relay_notify functions from the file
4745 silcd/packet_send.[ch].
4749 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4750 server. Affected file silcd/packet_receive.[ch].
4752 * Implemented the KILL command to the client. Implemented the
4753 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4754 Affected files lib/silcclient/command[_reply].c and
4755 lib/silcclient/client_notify.c. Implemented the KILL notify
4756 printing in the user inteface.
4758 * Fixed a lot silc_parse_nick memory leaks from the client
4759 library in the file lib/silcclient/command.c.
4761 * Changed the silc_server_send_notify_on_channels's `sender'
4762 argument from SilcSocketConnection to SilcClientEntry to
4763 check the sender as entry and not as connection object and not
4764 to send to the client provided as argument. The affected file
4765 is silcd/packet_send.[ch].
4767 * The notify packets that are destined directly to the client used
4768 to not to be processed by the server. Now changed that and the
4769 server processes all notify packets. After relaying the packet
4770 to the client the notify packet is processed in the server.
4772 * The silc_server_free_client_data now checks whether there is
4773 pending outgoing traffic for the client and purges the data to
4774 the network before removing the client entry.
4776 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4778 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4779 an client is killed from the SILC Network. Updated the protocol
4782 Added new function silc_server_send_notify_killed to the
4783 silcd/packet_send.[ch].
4785 * Added function silc_server_packet_relay_notify to relay notify
4786 packets that are destined directly to a client. In this case
4787 the server does not process the notify packets but merely relays
4788 it to the client. Affected file silcd/packet_send.[ch].
4790 Added also silc_server_packet_process_relay_notify to check
4791 whereto relay the notify. Affected file is
4792 silcd/packet_receive.[ch].
4794 * Implemented the KILL command to the server.
4798 * Added the backup schema desgined last fall to the protocol
4799 specs for everyone to see. The specification is in the
4800 *-spec-xx.txt draft and the packet type definitions for the
4801 backup routers is in *-pp-xx.txt draft. Thusly, added also
4802 new packet type SILC_PACKET_CELL_ROUTERS.
4804 * A big security problem in the implementation discovered. The
4805 signoff of an client did not cause new channel key generation
4806 which it of course should've done. The channel keys must be
4807 always re-generated when client leaves (or signoffs) the channel.
4808 The silc_server_remove_from_channels funtion now handles
4809 the channel key re-generation.
4811 * Added `sender' argument to the silc_server_send_notify_on_channels
4812 to not to send the client provided as argument. Affected file
4813 silcd/packet_send.[ch].
4815 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4817 * Implemented OPER and SILCOPER commands into the server and
4820 * Added silc_auth_verify and silc_auth_verify_data to verify
4821 the authentication directly from the authentication payload.
4822 It supports verifying both passphrase and public key based
4823 authentication. Affected file lib/silccore/silcauth.[ch].
4825 * Added `hash' field to the SilcIDListData structure. It is the
4826 hash negotiated in the SKE protocol. Affected file is
4829 * Slight redesigning of the SilcAuthPayload handling routines.
4830 Do not send SilcPKCS but SilcPublicKey as argument.
4832 * Implemented the public key authentication support to the
4833 serverconfig. The public key is loaded from the provided path
4834 and saved as authentication data to void * pointer. Thus,
4835 changed the unsigned char *auth_data to void *auth_data;
4837 * Fixed SHUTDOWN command to send the reply before the server
4838 is shutdown. :) Affected file silcd/command.c.
4840 * Fixed fatal bug in CONNECT command. The hostname was invalid
4841 memory and server crashed. Affected file silcd/command.c.
4843 * Fixed fatal bug in CLOSE command. The server_entry became
4844 invalid but was referenced later in the command. Affected file
4847 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4849 * Fixed fatal bug in failure packet handling. Server ignored
4850 the failure and thus crashed when it came.
4854 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4856 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4857 that the command may be executed only once in (about) 2 seconds.
4858 The old SILC_CF_LAG flag is same but allows command bursts up
4859 to five before limiting.
4861 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4862 server code. Various commands now includes the CF_LAG_STRICT
4863 flag to disallow any kind of miss-use of the command.
4865 * Fixed the silc_buffer_unformat to not to allocate any data
4866 if the length of the data is zero. It used to allocate the
4867 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4869 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * Changed the format of AdminConnection configuration section
4872 in the server. Added username of the admin to the format.
4873 Affected files silcd/serverconfig.[ch].
4875 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4876 to return admin configuration data by host, username and/or
4879 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4881 * Implemented WHOWAS command to the server. Added the functions:
4883 silc_server_command_whowas_parse,
4884 silc_server_command_whowas_send_reply,
4885 silc_server_command_whowas_from_client and
4886 silc_server_command_whowas_from_server
4888 * Added <Client ID> argument to the WHOWAS command reply. Updated
4889 the protocol specs accordingly.
4891 * Implemented WHOWAS command and command_reply to the client
4894 Implemented the WHOWAS printing on the user interface.
4896 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4898 * Added new argument to the WHOWAS command reply, the real name.
4899 It is an optional argument. Updated the protocol specs.
4901 * Added SilcIDCacheDestructor callback that is registered when
4902 the SilcIDCache is allocated. The callback is called when
4903 an cache entry in the ID Cache expires, or is purged from the
4904 cache. Added into lib/silccore/idcache.[ch].
4906 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4907 to destruct the client entries when the cache entry expires.
4908 Other ID Cache's in server and in the client library ignores
4911 * If the ID Cache entry's `expire' field is zero then the entry
4912 never expires. Added boolean `expire' argument to the
4913 silc_idcache_add function in the lib/silccore/idcache.[ch].
4914 If it is TRUE the default expiry value is used.
4916 * Added silc_server_free_client_data_timeout that is registered
4917 when client disconnects. By default for 5 minutes we preserve
4918 the client entry for history - for WHOWAS command.
4920 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4922 * Added support to the server to enforce that commands are not
4923 executed more than once in 2 seconds. If server receives
4924 commands from client more frequently, timeout is registered
4925 to process the commands. Affected file silcd/command.c.
4926 Added new function silc_server_command_process_timeout.
4928 * Changed NICK_NOTIFY handling in client library to check that
4929 if the client's nickname was changed, so there is no need to
4930 resolve anything from the server.
4932 * Removed error printing from the WHOIS and IDENTIFY commands.
4933 If error occurs then it is ignored silently in the client library.
4934 The application, however, may map the received error to
4935 human readable error string. The application currently maps
4936 the NO_SUCH_NICKNAME error to string.
4938 * Made the command status message public to the application. Moved
4939 them from lib/silcclient/command_reply.c to
4940 lib/silcclient/command_reply.h. The application can map the
4941 received command status to the string with the
4942 silc_client_command_status_message function.
4944 * Added check to the server to check that client's ID is same
4945 as the Source ID in the packet the client sent. They must
4948 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4950 * Added dist-bzip hook to the Makefile.am to make bzip2
4951 compressed distributions.
4953 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4955 * Server now enforces the maximum length for the nickname and
4956 the channel as protocol specification dictates. 128 bytes for
4957 nickname and 256 bytes for channel name.
4959 * Moved the WHOIS printing to the application. The client libary
4960 does not print out the WHOIS information anymore, the application
4961 must do it. Renamed silc_client_command_reply_whois_print to
4962 the silc_client_command_reply_whois_save.
4964 The client's idle time is also sent to the application now, and
4965 the idle is shown on screen.
4967 * Added silc_client_command_reply_identify_save to save the
4968 received IDENTIFY entries.
4970 * Do not check for channel private keys in message sending and
4971 reception if the channel does not have the PRIVKEY mode set.
4972 Affected file lib/silclient/client_channel.c.
4974 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4977 just surfaced after chaning the JOIN procedure.
4979 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4981 * Added silc_client_get_clients_by_list to get client entries
4982 from Client ID list, that is returned for example by JOIN
4983 and USERS command replies. The application should use this
4984 function for example when JOIN command reply is received to
4985 resolve the clients already on the channel (library does not
4986 do that anymore as USERS command reply is not used in the JOIN
4987 procedure anymore). Affected files lib/silcclient/silcapi.h and
4988 lib/silcclient/idlist.c.
4990 * JOIN command reply and USERS command reply returns now SilcBuffer
4991 pointers instead of unsigned char pointers when returning
4992 the client list and mode list.
4994 * Added <Client ID> argument to the JOIN command reply, mainly
4995 for the server to identify for which client the command was
4996 originally sent. Updated protocol specs accordingly.
4998 * Added SilcDlist private_key pointer to the SilcChannelEntry
4999 in the client to support the channel private keys. Affected
5000 file is lib/silcclient/idlist.h.
5002 * Added SilcChannelPrivateKey argument to the function
5003 silc_client_send_channel_message so that application can choose
5004 to use specific private ke if it wants to. If it is not provided,
5005 the normal channel key is used, unless private keys are set.
5006 In this case the first (key that was added first) is used
5007 as the encryption key.
5009 * Implemented the support for channel private key handling.
5010 Implemented the following functions:
5012 silc_client_add_channel_private_key,
5013 silc_client_del_channel_private_keys,
5014 silc_client_del_channel_private_key,
5015 silc_client_list_channel_private_keys and
5016 silc_client_free_channel_private_keys
5018 Affected file lib/silcclient/client_channel.c.
5020 * Added the support for the private keys in the channel message
5021 sending and encryption and in the message reception and
5022 decryption. Affected funtions are
5023 silc_client_send_channel_message and silc_client_channel_message.
5025 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Added SKE's key verify callback to the client library's
5028 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5030 * Removed the statement that server (or router) must send USERS
5031 command reply when joining to the channel so that the client
5032 knows who are on the channel. Instead, the client list and
5033 client's mode list is now sent in the JOIN command reply to the
5034 client who joined channel. This is better solution.
5036 * Added function silc_server_get_users_on_channel and function
5037 silc_server_save_users_on_channel to the silcd/server.[ch].
5039 * Removed function silc_server_command_send_users from the
5042 * Do not show topic on the client library anymore. The topic is
5043 sent in the command reply notify to the application and the
5044 application must show the topic now.
5046 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5048 * Added client searching by nickname hash into the IDENTIFY and
5049 WHOIS commands in the server as they were clearly missing from
5050 them. Affected file is silcd/command.c.
5052 * Fixed a bug in private message receiving in the client library.
5053 The remote ID was freed and it wasn't supposed, now it is
5056 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * Minor fix to the channel payload; allocate the data area, as it
5059 needs to be of specific length.
5061 * If the key agreement port is zero then the operating
5062 system will define the bound port. Affected files are
5063 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5065 * Added new function silc_channel_payload_decrypt into the file
5066 lib/silccore/silcchannel.[ch].
5068 * Moved the channel message etc, check from silc_packet_decrypt
5069 to applications. The library calls now a generic
5070 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5071 when the packet is either normal or special. This was done to
5072 allow more wide range of checking that was not allowed when
5073 the code was in library. Now applications can do virtually any
5074 checks to the packet and return to the library the decision how
5075 the packet should be processed. Affected files are
5076 lib/silccore/silcpacket.[ch].
5078 Added silc_server_packet_decrypt_check to the server and
5079 silc_client_packet_decrypt_check to the client library.
5081 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5082 to send with specified source and destination information.
5084 * Channel message delivery between routers was broken after the
5085 channel key distribution was fixed earlier. The channel key
5086 was used be to distributed to other routers as well which is not
5087 allowed by the protocol. Now this is fixed and channel keys
5088 really are cell specific and the channel message delivery between
5089 routers comply with the protocol specification.
5091 * Fixed various commands in server to check also the global list
5092 for the channel entry and not just the local list. The affected
5093 file silcd/command.c.
5095 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5097 * Added assert()s to buffer formatting and unformatting routines
5098 to assert (if --enable-debug) when error occurs. Affected
5099 file: lib/silcutil/silcbuffmt.c.
5101 * Changed to auto-reconnect to check whether the remote host is
5102 router and register the re-connect timeout if it is. It used
5103 to check that whether we are normal server, but router must do
5104 auto-reconnect with another router as well. Affected file
5107 * Removed the [<key len>] option from CMODE command as the cipher
5108 name decides the key length, nowadays. See the defined ciphers
5109 from the protocol specification.
5111 * Added [<hmac>] option to the CMODE command to define the HMAC
5112 for the channel. Added SILC_CMODE_HMAC channel mode.
5114 * Added [<hmac>] option for the JOIN command so that user can
5115 select which HMAC is used to compute the MACs of the channel
5118 * Added Hmac field to the Channel Message Payload. The integrity
5119 of plaintext channel messages are now protected by computing
5120 MAC of the message and attaching the MAC to the payload. The
5121 MAC is encrypted. Now, it is clear that this causes some
5122 overhead to the size of the packet but rationale for this is that
5123 now the receiver can verify whether the channel message decrypted
5124 correctly and also when private keys are set for the channel the
5125 receiver can decrypt the packet with several keys and check from
5126 the MAC which key decrypted the message correctly.
5128 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5129 lib/silccrypt/silccipher.[ch].
5131 * Added silc_hash_len to return the digest length into the
5132 lib/silcrypt/silchash.[ch].
5134 * Rewrote parts of Silc Channel Payload interface in the
5135 lib/silccore/silcchannel.[ch]. The encode function now also
5136 encrypts the packet and parse function decrypts it.
5138 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5140 * Fixed a minor formatting bug in the SKE's key material processing.
5141 It actually might have processed the keys wrong way resulting
5144 * Redefined the mandatory HMAC algorithms and added new algorithms.
5145 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5146 and hmac-md5 truncated to 96 bits. The mandatory is now
5147 hmac-sha1-96. Rest are optional (including the one that used
5148 to be mandatory). Rationale for this is that the truncated HMAC
5149 length is sufficient from security point of view and can actually
5150 make the attack against the HMAC harder. Also, the truncated
5151 HMAC causes less overhead to the packets. See the RFC2104 for
5154 * Added new [hmac] configuration section. The SKE used to use
5155 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5156 is of course wrong. The official names that must be proposed in
5157 the SKE are the ones defined in the protocol specification
5158 (hmac-sha1-96 for example). The user can configure any hmac
5159 using any hash function configured in the [hash] section. At
5160 least, the mandatory must be configured.
5162 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5164 * Added HMAC list to the SKE proposal list. It has now both
5165 hash algorithm list and HMAC list. This makes the protocol
5166 incompatible with previous versions. The SKE now seems to work
5167 the way it is supposed to work, for the first time actually.
5169 * Defined plain Hash algorithms to the protocol specification.
5172 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5174 * Implemented support for key agreement packets into the server.
5175 Added functions silc_server_key_agreement and
5176 silc_server_send_key_agreement. Other than these functions,
5177 server has nothing to do with this packet.
5179 * Added support for private message key packets into the server.
5180 Added functions silc_server_private_message_key and
5181 silc_server_send_private_message_key.
5185 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5186 called in the protocol's final callback instead in the END
5187 protocol state. This makes a little more sense and in the same
5188 time in client we can use the same protocol routines for normal
5189 key exchange and to key agreement packet handling as well.
5191 * Added to both client's and server's KE protocol context the
5192 SilcSKEKeyMaterial pointer to save the key material. We will
5193 bring the key material to the protocol's final callback by doing
5194 this. The final callback must free the key material.
5196 * Added SKE's packet_send callback into client's KE protocol
5197 context so that the caller can choose what packet sending function
5198 is used. This way we can use different packet sending when
5199 doing normal SKE when doing key agreement packet handling (in
5200 the key agreement packet handling we do not want to encrypt
5203 * Implemented the responder side of the key agreement routines
5204 in the client. The client can now bind to specified port and
5205 accept incoming key negotiation. The key material is passed
5206 to the application after the protocol is over.
5208 * Implemented the processing of incoming Key Agreement packet
5209 in the client. Added function silc_client_key_agreement to
5212 * Implemented the intiator side of the key agreement routines
5213 in the client. The client can now initiate key agreement with
5214 another remote client. The key material is passed to the
5215 application after the protocol is over.
5217 * Created client_keyagr.c to include all the key agreement
5220 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5221 SILC_TASK_CALLBACK except that it is not static.
5223 * Created client_notify.c and moved the Notify packet handling
5224 from the client.[ch] into that file.
5226 * Created client_prvmsg.c and moved all private message and
5227 private message key routines from the client.[ch] into that file.
5229 * Create client_channel.c and moved all channel message and
5230 channel private key routines from the client.[ch] into that file.
5232 * Changed silc_client_get_client_by_id_resolve to resolve with
5233 WHOIS command instead of IDENTIFY command, in the file
5234 lib/silclient/idlist.c.
5236 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5238 * Implemented the SKE's responder side to the Client library.
5240 * When FAILURE is received to the protocol do not trust it
5241 blindly. Register a timeout to wait whether the remote closes
5242 the connection as it should do it, only after that process the
5243 actual failure. This was changed to both client and server.
5245 * Added client_internal.h to include some of the structures
5246 there instead of client.h in lib/silcclient/.
5248 * Added function silc_task_unregister_by_callback to unregister
5249 timeouts by the callback function.
5251 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5253 * Some "Incomplete WHOIS info" errors has been appearing on the
5254 log files. Took away the entry->userinfo check from WHOIS
5255 reply sending. The entry->userinfo is now " " if client did not
5256 provide one. I thought this was fixed earlier but something
5257 is wrong still. Let's see if the error still appears.
5259 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5261 * Fixed a minor bug in the login when the channel key is
5262 re-generated in the server. It used to generate the key in
5263 wrong order and thus caused problems in the channel traffic.
5265 * Fixed a minor bug in channel key distsribution after
5266 KICK command. The key was not sent to the router even though
5269 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * Added silc_ske_process_key_material_data as generic routine
5272 to process any key material as the SILC protocol dictates. The
5273 function is used by the actual SKE library but can be used by
5274 applications as well. This relates to the private message keys
5275 and the channel private keys since they must be processed the
5276 same way the normal SILC session keys. The protocol dictates
5277 this. Affected files: lib/silcske/silcske.[ch].
5279 Added also silc_ske_free_key_material to free the
5280 SilcSKEKeyMaterial structure.
5282 * Defined silc_cipher_set_key function to set the key for
5283 cipher without using the object's method function. The affected
5284 files: lib/silccrypt/silccipher.[ch].
5286 * Implemented silc silc_client_add_private_message_key,
5287 silc_client_add_private_message_key_ske,
5288 silc_client_del_private_message_key,
5289 silc_client_list_private_message_keys and
5290 silc_client_free_private_message_keys functions in the
5293 Added functions silc_client_send_private_message_key to send
5294 the Private Message Key payload and silc_client_private_message_key
5295 to handle incoming Private Message Key payload.
5297 * Added Cipher field to the Private Message Key payload to set
5298 the cipher to be used. If ignored, the default cipher defined
5299 in the SILC protocol (aes-256-cbc) is used.
5301 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Removed lib/silcclient/ops.h file.
5305 Redefined parts of the SILC Client Library API. Created new
5306 file silcapi.h that deprecates the ops.h file and defines the
5307 published Client Library API. Defined also private message key
5308 API and channel private key API into the file.
5310 This is the file that the application must include from the
5311 SILC Client Library. Other files need not be included by
5312 the application anymore.
5314 * Added new key_agreement client operation callback and also
5315 defined the Key Agreement library API for the application.
5317 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5320 is used by clients to request key negotiation between another
5321 client in the SILC network. If the negotiation is started it
5322 is performed using the SKE protocol. The result of the
5323 negotiation, the secret key material, can be used for example
5324 as private message key.
5326 Implemented the Key Agreement payload into the files
5327 lib/silccore/silauth.[ch].
5329 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5331 * Redefined ciphers for the SILC protocol. Added some new ciphers
5332 and defined the key lengths for the algorithms. Changed the
5333 code accordingly. The default key length is now 256 bits.
5335 * Fixed SKE key distribution function silc_ske_process_key_material
5336 when the key length is more than 128 bits. The default key
5337 length in SILC is now 256 bits.
5339 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5340 to indicate unsupported algorithm.
5342 * Renamed rijndael.c to aes.c and all functions as well.
5344 * Fixed a long standing channel key setting bug in client library.
5345 Weird that it has never surfaced before.
5347 * Fixed bug in channel deletion. If the entire channel is removed
5348 then it must also delete the references of the channel entry
5349 from the client's channel list as the client's channel entry and
5350 the channel's client entry share same memory.
5352 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5354 * Implemented CONNECT and SHUTDOWN commands in the client.
5356 * Implemented CLOSE command to the client.
5358 * Added the function silc_idlist_find_server_by_name into the
5359 files silcd/idlist.[ch].
5361 Added the function silc_idlist_find_server_by_conn into the
5362 files silcd/idlist.[ch].
5364 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5366 * DIE command was renamed to SHUTDOWN. Updated the both code
5369 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5370 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5372 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5375 * Added function silc_server_create_connection function to create
5376 connection to remote router. My server implementation actually
5377 does not allow router to connect to normal server (it expects
5378 that normal server always initiates the connection to the router)
5379 so the CONNECT command is only good for connecting to another
5382 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5384 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5385 or some other client was kicked from the channel.
5387 Implemented the handling of the notify type to both client
5390 Implemented silc_server_send_notify_kicked to send the KICKED
5391 notify. It is used to send it to the server's primary router.
5393 * Implemented the KICK command into server and client.
5395 * Added `query' argument to the silc_idlist_get_client function
5396 to indicate whether to query the client from server or not if
5399 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5400 to indicate that the client is not channel founder.
5404 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Removed the rng context from SilcPacketContext structure and
5407 changed that the packet routine uses the Global RNG API.
5409 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5411 * Added support for quit message that client can "leave" on the
5412 channel when it quits the SILC. It is ditributed inside the
5413 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5415 Added silc_server_free_client_data that will take the
5416 signoff message as argument.
5418 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5420 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5422 * Updated parts of the protocol specification to keep it up
5425 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5427 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5428 payloads in one packet.
5430 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5431 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5432 use now the new List flag.
5434 * Also deprecated the following packet types: REPLACE_ID,
5435 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5437 * Added list support for Notify packet in server.
5439 * Added silc_server_send_notify_channel_change to send the
5440 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5441 the silc_server_send_replace_id.
5443 * Added silc_server_send_notify_nick_change to send the
5444 NICK_CHANGE notify type. Deprecates the function
5445 silc_server_send_replace_id.
5447 * Added silc_server_send_notify_join to send the JOIN notify type.
5448 Deprecates the function silc_server_send_new_channel_user.
5450 * Added silc_server_send_notify_leave to send LEAVE notify type.
5451 Deprecates the function silc_server_send_remove_channel_user.
5453 * Added silc_server_send_notify_cmode and
5454 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5455 types. Deprecates the silc_server_send_set_mode function.
5457 * Added SERVER_SIGNOFF notify type to indicate that server has
5458 quit. This means that all clients on the channel from that
5459 server will drop. This can be also used when netsplit happens.
5461 Deprecated REMOVE_ID packet type since it is not needed anymore
5464 Added silc_server_send_notify_server_signoff to send the
5465 SERVER_SIGNOFF notify type. Deprecates the function
5466 silc_server_send_remove_id.
5468 Added also silc_server_send_notify_signoff to send the
5469 SIGNOFF notify type.
5471 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5472 SILC protocol from this day on. Changed the protocol
5473 specification as well.
5475 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5476 notify type. It is used between routers to notify about
5477 topic changes on a channel.
5479 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5482 * Partly updated the protocol specification to comply with the
5483 changes now made. It is still though a bit outdated.
5485 * The JOIN notify type now takes one extra argument <Channel ID>.
5486 The packet used to be destined to the channel but now the
5487 JOIN type may be sent as list thus it is impossible to
5488 destine it to any specific channel. By adding this argument
5489 it is again possible.
5491 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5493 * Added CREDITS file. The CHANGES and CREDITS file will appear
5494 in the distribution as well.
5496 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5498 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5499 types in the server's silcd/packet_receive.c.
5501 * Implemented CMODE and CUMODE to work in router environment.
5503 * Fixed minor encoding and decoding buglet from the
5504 lib/silccore/silcmode.c.
5506 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5509 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5511 * Changed all SilcConfigServer* and silc_config_server* to
5512 SilcServerConfig* and silc_server_config*, respectively.
5515 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Associated the ID (client or server ID) to the Authentication
5518 Payload to avoid any possibility of forging. Updated the
5519 protocol specification and the code accordingly.
5521 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5523 * The RSA key length is now save to the RsaKey context in the
5524 key generation process in lib/silccrypt/rsa.c. The key length
5525 is now used to figure out the maximum size of the block allowed
5526 to be encrypted/signed.
5528 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5529 is equivalent to the silc_mp_mp2bin but does not allocate any
5532 * Changed silc_mp_mp2bin API to take length argument. If it is
5533 non-zero then the buffer is allocated that large. If zero, then
5534 the size is approximated using silc_mp_sizeinbase, which however
5537 * Created Global RNG API which is global RNG that application can
5538 initialize. After initializing, any routine anywhere in the
5539 code (including library) can use RNG without allocating a new
5540 RNG object. This was done to allow this sort of use of the
5541 RNG in code that has no chance to allocate RNG object. All
5542 applications currently allocate this and many routines in the
5543 library use this. Affected file lib/silccrypt/silcrng.[ch].
5545 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5546 it to use the Global RNG API.
5548 * Defined Authentication Payload into protocol specification that
5549 is used during SILC session to authenticate entities. It is
5550 used for example by client to authenticate itself to the server
5551 to obtain server operator privileges.
5553 Implemented this payload into the lib/silccore/silcauth.[ch].
5554 Implemented also routines for public key based authentication
5555 as the new protocol specification dictates.
5557 Moved definitions of different authentication methods from
5558 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5560 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5561 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5562 silc_pkcs_verify_with_hash functions into the file
5563 lib/silccrypt/silcpkcs.[ch].
5565 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5567 * The client entry's userinfo pointer must be always valid.
5568 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5569 will fail since it requires the userinfo. Now, the userinfo
5570 is allocated as "" if actual userinfo does not exist. Actually,
5571 it must exist and it is totally Ok to drop client connections
5572 that does not announce the userinfo. However, we will make
5573 this workaround for now.
5575 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5576 to return the remote port by socket.
5578 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5580 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5581 SILC_SERVER_PENDING_EXEC and added an new macro
5582 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5583 data or when error occurs while processing the pending command.
5585 Added new argument `destructor' into silc_server_command_pending
5586 and to the SilcServerCommandPending object. This destructor is
5587 now called after calling the pending callback or if error occurs
5588 immediately. If error occurs the actual pending callback won't
5589 be called at all - only the destructor. The destructor may be
5590 NULL if destructor is not needed.
5592 All this applies for client library code as well. Similar
5593 changes were made there as well for the pending commands.
5595 In the client, the application must now allocate the
5596 SilcClientCommandContext with the silc_client_command_alloc
5599 * Added reference counter to the SilcServerCommandContext. Added
5600 function silc_server_command_alloc and silc_server_command_dup
5603 Same type of functions added to the client library for the same
5606 * Removed the cmd_ident from IDListData away since it is now
5607 global for all connections. It is the command identifier used
5608 in command sending and with pending commands. The affected file
5611 * Added reference counter to the SilcSocketConnection objecet to
5612 indicate the usage count of the object. The object won't be
5613 freed untill the reference counter hits zero. Currently only
5614 server uses this, and client ignores it. The client must be
5615 set to use this too later. The affected files are
5616 lib/silccore/silcsockconn.[ch]. Added also the function
5617 silc_socket_dup to increase the reference counter.
5619 This was mainly added because it is possible that the socket
5620 is removed underneath of pending command or other async
5621 operation. Now it won't be free'd and proper DISCONNECTING
5622 flags, etc. can be set to avoid sending data to connection that
5623 is not valid anymore.
5625 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5626 the connection. After that it sets SILC_SET_DISCONNECTED.
5627 It is, however, possible that the socket data is not still freed.
5628 The silc_server_packet_process now checks that data is not
5629 read or written to connection that is DISCONNECTED. The socket
5630 get's freed when the reference counter hits zero.
5632 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5634 * Changed the client operation API: channel_message operation's
5635 `sender' is now the client entry of the sender, not the nickname
5636 and the `channel' is the channel entry, not the channel name.
5638 In the private_message operation the `sender' is now also the
5639 client entry of the sender not the nickname.
5641 Affected file is lib/silcclient/ops.h and all applications
5642 using the client operations.
5644 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5646 * Moved the calling of ops->connect() from connect_to_server_final
5647 into receive_new_id functin since that is the point when the
5648 client is actually allowed to send traffic to network. The
5649 affected file is lib/silcclient/client.c.
5651 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5653 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5654 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5655 (if needs broadcasting) instead of broadcasting the packets one
5656 by one which would make a burst in the network traffic.
5658 * Added `broadcast' argument to the functions in silcd/server.[ch]
5659 silc_server_create_new_channel[_with_id] to indicate whether
5660 to send New Channel packet to primary router.
5662 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5664 * Added new function into the silcd/server.[ch] files:
5665 silc_server_create_new_channel_with_id to create new channel with
5666 already existing Channel ID.
5668 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5669 lib/silccore/silcpacket.h. This packet is used t send list of
5670 Set Mode payloads inside one packet. Server uses this to set
5671 the modes for the channels and clients on those channels, that it
5672 announced to the router when it connected to it. The protocol
5673 specification has been updated accordingly.
5675 * The silc_server_new_channel did not handle the packet coming
5676 from normal server as it normally does not send that. However,
5677 when it announces its channels it does send it. Implemented
5678 the support for that.
5680 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5681 into the file lib/silccore/id.h.
5683 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5685 * Fixed memory leaks in the functions silc_idlist_del_client,
5686 silc_idlist_del_channel and silc_idlist_del_server in the file
5687 silcd/idlist.c. All of those leaked like a sieve.
5689 * Fixed some small memory leaks in the client's function
5690 silc_client_notify_by_server.
5692 * Added functions into silcd/server.c: silc_server_announce_clients,
5693 silc_server_announce_channels and silc_server_announce_server.
5694 These functions are used by normal and router server to announce
5695 to its primary router about clients, channels and servers (when
5696 router) that we own. This is done after we've connected to the
5699 These functions effectively implements the following packet types:
5700 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5701 and SILC_PACKET_NEW_ID_LIST.
5703 * Added new functions into the silcd/packet_receive.[ch]:
5704 silc_server_new_id_list, silc_server_new_channel_list and
5705 silc_server_new_channel_user_list to handle the incoming
5706 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5708 * Added support of changing Channel ID in the function
5709 silc_server_replace_id. If the server that announces a channel
5710 to the router already exists in the router (with same name but
5711 with different Channel ID), router is responsible to send
5712 Replace ID packet to the server and force the server to change
5713 the Channel ID to the one router has.
5715 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5716 client that the Channel ID has been changed by the router. The
5717 normal server sends this to the client. Client must start using
5718 the new Channel ID as the channel's ID.
5720 Implemented handling of this new type into lib/silcclient/client.c
5721 into the function silc_client_notify_by_server.
5723 * Added new function silc_idlist_replace_channel_id into the files
5724 silcd/idlist.[ch] to replace the Channel ID.
5726 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5728 * Call silc_server_command_identify_check always when processing
5729 the IDENTIFY command in silcd/command.c
5731 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5733 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5734 send keepalive packets. The packet can be sent by clients,
5735 servers and routers.
5737 Added function silc_socket_set_heartbeat into the file
5738 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5739 If not set, the heartbeat is not performed. The actual
5740 heartbeat is implemented in the low level socket connection
5741 library. However, application is responsible of actually
5744 Added silc_server_send_heartbeat to send the actual heartbeat
5745 packet into silcd/packet_send.[ch]. Server now performs
5746 keepalive with all connections.
5748 * Added silc_task_get_first function into lib/silcutil/silctask.c
5749 to return the timeout task with shortest timeout. There was a bug
5750 in task unregistration that caused problems. TODO has been
5751 updated to include that task system must be rewritten.
5753 * The client library will now resolve the client information when
5754 receiving JOIN notify from server for client that we know but
5755 have incomplete information.
5757 * Rewrote parts of silc_server_remove_from_channels and
5758 silc_server_remove_from_one_channel as they did not remove the
5759 channel in some circumstances even though they should've.
5761 * Encryption problem encountered in server:
5763 The LEAVE command used to send the Channel Key packet to the
5764 router immediately after generating it. However, the code
5765 had earlier sent Remove Channel user packet but not immediately,
5766 ie. it was put to queue. The order of packets in the router
5767 was that Channel Key packet was first and Remove Channel User
5768 packet was second, even though they were encrypted in the
5769 reverse order. For this reason, MAC check failed. Now, this
5770 is fixed by not sending the Channel Key packet immediately but
5771 putting it to queue. However, this is more fundamental problem:
5772 packets that are in queue should actually not be encrypted
5773 because packets that are sent immediately gets encrypted
5774 actually with wrong IV (and thus MAC check fails). So, packets
5775 that are in queue should be encrypted when they are sent to
5776 the wire and not when they put to the queue.
5778 However, the problem is that the current system has not been
5779 designed to work that way. Instead, the packet is encrypted
5780 as soon as possible and left to the queue. The queue is then
5781 just purged into wire. There won't be any fixes for this
5782 any time soon. So, the current semantic for packet sending
5785 o If you send packet to remote host and do not force the send
5786 (the packet will be in queue) then all subsequent packets to the
5787 same remote host must also be put to the queue. Only after the
5788 queue has been purged is it safe again to force the packet
5791 o If you send all packets immediately then it safe to send
5792 any of subsequent packets through the queue, however, after
5793 the first packet is put to queue then any subsequent packets
5794 must also be put to the queue.
5796 Follow these rules and everything works fine.
5798 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5800 * Added new function silc_server_remove_clients_by_server to
5801 remove all client entries from ID list when the server connection
5802 is lost. In this case it is also important to invalidate all
5803 client entires as they hold the invalid server entry. This
5804 fixes fatal bug when server has lost connection and will reconnect
5807 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5809 * Made some sanity checks to silc_server_daemonise like to check
5810 whether the requested user and group actually exists.
5812 * Added sanity check to SKE's silc_ske_responder_finish to check
5813 that the public and private key actually is valid.
5815 * Invalidate the client's nickname when receiving Replace ID
5816 packet and the Client ID is being replaced. This means that the
5817 server will query the nickname if someone needs it (client)
5820 * Sort the ID Cache in client library when the ID Cache data
5821 has changed (needs sorting).
5823 * Do not allow for SILC client to create several connections to
5824 several servers. The client does not support windows right now
5825 and generating multiple connections causes weird behaviour.
5827 Irssi-silc client does support windows and can handle several
5828 connections without problems, see: www.irssi.org and SILC plugin.
5830 * Fixed some places where client was added to the IDList. The
5831 rule of thumb is following (in order to get everything right):
5832 If the client is directly connected local client then the
5833 `connection' argument must be set and `router' argument must be
5834 NULL to silc_idlist_add_client function. If the client is not
5835 directly connected client then the `router' argument must
5836 bet set and the `connection' argument must be NULL to the
5837 silc_idlist_add_client function.
5839 * The funtion silc_server_packet_send_local_channel actually did
5840 not check whether the client was locally connected or not. It
5841 does that now. Fixed a bug related to LEAVE command.
5843 * Fixed Remove Channel User payload parsing bug in server's
5844 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5846 * The server's silc_server_save_channel_key now checks also the
5847 global ID list for the channel as it might not be in the local
5848 list. Fixed a bug related to LEAVE command.
5850 * Is this the end of the [<unknown>] buglet that has been lurking
5851 around for a long time? A little for loop fix in server's
5852 silc_server_command_whois_parse that is used by both IDENTIFY
5853 and WHOIS command. At least, this was a clear bug and a cause
5854 of one type of [<unknown>] buglet.
5856 * WHOIS and IDENTIFY commands call the function
5857 silc_server_command_[whois/identify]_check function even if
5858 we are not router server.
5860 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5862 * Added --with-gmp configuration option. If set the GMP
5863 is always compiled in the SILC source tree. If not set then
5864 it is checked whether the system has the GMP3 installed. If
5865 it has then the GMP won't be compiled (the system's headers
5866 and library is used), if it doesn't have it then the GMP is
5867 compiled in the SILC source tree.
5869 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5871 * Changed RSA private exponent generation to what PKCS #1
5872 suggests. We try to find the smallest possible d by doing
5873 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5874 not security fix but optimization.
5876 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * Added new config entry [Identity] to fork the server and run
5879 it as specific user and group. A patch from Bostik.
5881 * Imported Dotconf configuration library into lib/dotconf.
5882 This will be used to create the SILC configuration files later.
5883 It will appear in the distsribution after this commit.
5885 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5887 * A big code auditing weekend happening. Auditing code for
5888 obvious mistakes, bugs and errors. Also, removing any code
5891 Removed files for being obsolete:
5893 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5894 inline in the file lib/silcutil/silcbuffer.h)
5896 o lib/silcutil/silcbufutil.c (the header has inline versions)
5898 Changed code to fix possible error conditions:
5900 o The buffer formatting routines now check that the destination
5901 buffer really has enough space to add the data. This applies for
5902 both buffer formatting and unformatting
5903 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5904 unformatting was changed to accomodate following rules:
5905 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5906 sent to the function while XXX_*STRING will not allocate or copy
5907 the data into the buffer. Instead it sets the pointer from the
5908 buffer into the pointer sent as argument (XXX_*STRING used to
5909 require that the pointer must be allocated already). This change
5910 makes this whole thing a bit more consistent and more optimized
5911 (note that the data returned in the unformatting with XXX_*STRING
5912 must not be freed now). The routines return now -1 on error.
5914 o Tried to find all code that use buffer_format and buffer_unformat
5915 and added return value checking to prevent formatting and
5916 especially unformatting errors and possible subsequent fatal
5919 o Changed ske->x and ske->KEY to mallocated pointers in
5920 lib/silcske/silcske.h. Fixed possible data and memory leak.
5922 o Added return value checking to all *_parse* functions. Fixed
5923 many memory leaks as well.
5925 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5926 so that buffer overflows would not happen. All code now also
5927 checks the return value as it can fail.
5929 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * Added reconnection support to server if the normal server looses
5932 its connection to the router (for example if router is rebooted).
5933 The server performs normal reconnection strategy implemented
5934 to the server. Affected file silcd/server.c.
5936 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5938 * Added new packet type SILC_PACKET_SET_MODE that is used to
5939 distribute the information about changed modes (for clients,
5940 channels and clients channel modes) to all routers in the
5941 network. Updated the protocol specification accordingly.
5943 Added functions into silcd/packet_send.c and
5944 silcd/packet_receive.c: silc_server_send_set_mode,
5945 silc_server_set_mode.
5947 Added new files silcmode.[ch] into lib/silccore that implements
5948 the encoding and decoding of Set Mode Payload. Added new type
5949 SilcSetModePayload. Moved the definitions of different modes
5950 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5952 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5954 * Oops, a little mistake in server's connection authentication
5955 protocol. The protocol is not ended with FAILURE but with
5956 SUCCESS if the authentication is Ok. :) Affected file is
5959 * Implemented NICK_CHANGE notify handling in server in the file
5960 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5961 the local clients on the channel. After the changing nickname
5962 in router environment snhould work and the [<unknown>] nickname
5963 should appear no more.
5965 The silc_server_replace_id function that receives the Replace ID
5966 payload now sends the NICK_CHANGE notify type also in the file
5967 silcd/packet_receive.c
5969 * Changed WHOIS and IDENTIFY command to support the maximum amount
5970 of arguments defined in protocol specs (3328 arguments). This
5971 fixed a bug that caused problems when there were more than three
5974 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5976 * Added extra parameter, command identifier, to the
5977 silc_client_send_command so that explicit command identifier
5980 Changed that ID list routines uses specific command identifier
5981 when sending WHOIS/IDENTIFY requests to the server so that they
5982 can be identified when the reply comes back.
5984 Affected files lib/silcclient/command.[ch],
5985 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5987 * Added `sender' argument to silc_server_packet_send_to_channel
5988 to indicaet the sender who originally sent the packet to us
5989 that we are now re-sending. Ignored if NULL. Affected file
5990 silcd/packet_send.[ch].
5992 * Added some server statistics support in silcd/server_internal.h
5993 SilcServerStatistics structure and around the server code. Also
5994 send some nice statistics information when client is connecting
5997 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5999 * Fixed channel ID decoding in server's JOIN command reply in
6000 silcd/command_reply.c
6002 * Fixed braodcasting of replace ID payload to not to send it if
6003 we are standalone server in silcd/packet_receive.c.
6005 * Fixed all channel message sending routines to not to send
6006 packets to clients that has router set, since they are routed
6007 separately in the same function earlier. Affects file
6008 silcd/packet_send.c and all channel packet sending functions.
6010 * In USERS reply, res_argv[i] are not allocated, the table
6011 is allocated. Thus changed that free the table, not its
6014 * In server's whois_check and identify_check if the client is
6015 locally connected do not send any WHOIS commands - they are not
6018 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6020 * Fixed some minor bugs in client when sending WHOIS command. The
6021 arguments was in wrong order.
6023 * Removed statis function add_to_channel from server in
6024 silcd/command.c that was previously used with the joining but
6027 * Tested USERS command in router environment successfully with two
6028 routers, two servers and two clients.
6030 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6032 * Reorganized the USERS command and command reply in client library
6033 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6034 When the command is given by user we register a pending command
6035 callback that will reprocess the command after the reply has been
6036 received from the server. When reprocessing the packet we then
6037 display the information. Thus, the USERS information is displayed
6038 now in the command callback instead of in the command reply
6039 callback. The processing of the command is same as previously
6040 when server has sent the command reply in the JOINing process.
6042 * Added to USERS command in silcd/command_reply.c to join the client,
6043 we didn't use to know about, to the channel after we've created
6044 a client entry for it. Also, for clienet we did know already still
6045 check whether it is on the channel or not and add it if not.
6047 * Removed silc_server_command_join_notify as the function and its
6050 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6052 * Changed the client's pending command handling to the same as the
6053 server's pending command handling. It is also now possible to
6054 execute command reply functions from other command reply
6055 function as the function callbacks for commands and command
6056 replies are one and same. The pending commands are not static
6057 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6058 in client connection context. Thus, pending commands are server
6059 connection specific as it is convenient.
6061 Changed the function silc_client_command_pending and
6062 silc_client_command_pending_del and added new function
6063 silc_client_command_pending_check. Removed the
6064 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6067 * Added cmd_ident, current command identifier, to the client
6068 connection context in lib/silcclient/client.h to keep track on
6069 command identifiers used in command sending. Client's command reply
6070 function handling now supports the mandatory command identifiers.
6072 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6073 funtions in client to fully support pending command callbacks.
6075 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6076 as one of the arguments to the application in the command reply
6079 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6080 before first releasing SILC but came back. Now it is removed again
6081 and should come back nomore. The FORWARDED flag was used only
6082 by the JOINing procedure by forwarding the command packet to router.
6083 Now, the JOINing procedure has been changed to more generic (due
6084 to various router environment issues) and FORWARDED is not needed
6085 anymore for anything. The protocol specification is yet to be
6088 Now, removed silc_server_packet_forward from server and the flag
6089 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6091 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6093 * Renamed NAMES command to USERS command. The NAMES was named that
6094 due to historical reasons. Now it is renamed. Also, rewrote
6095 parts of the USERS command. The nickname list is not sent anymore
6096 by the server. Only Client ID and mode lists are sent in the USERS
6097 command. Changed this also to the protocol specification.
6099 The client now resolves the names and stuff after it receives
6100 the USERS list from the server when joining to the channel.
6102 * WHOIS and IDENTIFY commands has been changed to support multiple
6103 Client ID's per command. One can now search for multiple users
6104 in the network by sending only one WHOIS or IDENTIFY command.
6105 Changed the code and the protocol specifications.
6107 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6108 uses silc_server_command_whois_parse to parse the request. */
6110 * If normal server, do not parse the WHOIS and IDENTIFY requests
6111 before sending it to the router. Saves some time.
6113 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6115 * Fixed JOIN command on client library. Wrong number of arguments
6116 used to crash the client.
6118 * Added silc_server_channel_has_global function to check whether
6119 channel has global users or not.
6121 * Added silc_server_channel_has_local function to check whether channel
6122 has locally connected clients on the channel.
6124 * The silc_server_remove_from_one_channel now checks whether the
6125 channel has global users or not after given client was removed from
6126 the channel. It also checks whether the channel has local clients
6127 on the channel anymore. If it does not have then the channel entry
6128 is removed as it is not needed anymore.
6130 * The silc_server_notify now checks on JOIN notify whether the joining
6131 client is one of locally connected or global. If it is global then
6132 the channel has now global users on the channel and that is marked
6133 to the channel entry. Also, it now saves the global client to
6134 global list who is joining and JOINs it to the channel. This is
6135 for normal server, that is.
6137 Changed silc_server_send_notify_on_channel,
6138 silc_server_packet_relay_to_channel and
6139 silc_server_packet_send_to_channel check if we are normal server
6140 and client has router set (ie. global client) do not send the
6141 message to that client, as it is already routed to our router.
6143 * Implemented LEAVE notify type handling in silc_server_notify
6146 * Tested LEAVE command in router environment successfully. Tested
6147 with two routers, two servers and two clients.
6151 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6153 * Implemented SIGNOFF notify type handling in silc_server_notify
6156 * silc_server_remove_id now removes the client entry from all channels
6157 it has joined and thusly sends SIGNOFF notify type.
6159 * Rewrote the NAMES list generation in server by removing two excess
6160 loops. The lists are created now inside one loop.
6162 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6164 * silc_server_remove_channel_user checks now also global list
6165 for channel and client.
6167 * silc_server_new_channel_user checks now both local and global
6168 list for channel and client. Fixed a bug in client id decoding.
6169 Used to decode wrong buffer.
6171 * silc_server_channel_message checks now both local and global
6172 list for channel entry.
6174 * Tested channel joining (hence JOIN) in router environment
6175 successfully. Tested with two routers, two servers and two
6178 * Tested channel message sending in router environment successfully.
6180 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6182 * Added silc_server_save_channel_key into server.[ch] to save the
6183 received channel key in Channel Key payload processing. It is
6184 also used in JOIN command reply handling.
6186 Equivalent function silc_client_save_channel_key added into
6187 client.[ch] into client library.
6189 * Changed JOIN command reply to send information whether the channel
6190 was created or not (is existing already) and the channel key
6191 payload. Changed protocol specs accordingly.
6193 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6194 the request was sent by ID and not by nickname. Crashed on
6197 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6200 now correctly save the received data.
6202 * silc_server_free_sock_user_data now notifies routers in the
6203 network about entities leaving the network.
6205 At the same time implemented functions silc_server_remove_id
6206 and silc_server_send_remove_id to receive and send REMOVE_ID
6207 packets. The packet is used to notify routers in the network
6208 about leaving entities. The ID removed will become invalid in
6211 * Added function silc_idlist_del_server into server. Removes and
6212 free's server entry from ID list.
6214 * silc_server_private_message function now checks, if we are router,
6215 that the destination ID really is valid ID, naturally.
6217 * In router when NEW_ID packet is received (for new client) the
6218 hash of the Client ID is saved in the ID Cache but the
6219 client->nickname is set to NULL, instead of putting the hash
6222 IDENTIFY command now also checks that client->nickname must be
6223 valid. If it is not if will request the data from the server who
6224 owns the client. Added new function
6225 silc_server_command_identify_check.
6227 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6228 to set the command to already allocated Command Payload.
6230 * Tested private message sending in router environment with two
6231 routers, two servers and two clients. Fixed minor bugs and now
6234 * Fixed segfault from client's NAMES command. Used to crash if
6237 * Forwarded packets must not be routed even if it is not destined
6238 to the receiver. Changed server code comply with this.
6240 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6242 * Added `require_reverse_mapping' boolean value to ServerParams
6243 structure. If TRUE (not default) the server will require that
6244 the connecting host has fully qualified domain name.
6246 If the reverse mapping is not required and hostname could not be
6247 found the IP address is used as hostname.
6249 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6251 * Implemented version string checking to both client and server.
6252 The check is incomplete currently due to the abnormal version
6253 strings used in development version of SILC.
6255 * Changed all command functions in server to use the new
6258 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Changed char *data to unsigned char *data in ID Cache system to
6261 support binary data as ID Cache data. Changed code to support
6262 binary data in lib/silccore/idcache.c.
6264 * Renamed silc_server_packet_relay_command_reply to
6265 silc_server_command_reply as it is normal packet receiving
6266 function. Rewrote the function to accept command replys for
6267 servers and not only for clients.
6269 * Mark remote router always as registered server if we are connecting
6270 to it. Otherwise, commands sent by the router to us are ignored.
6272 * All ID List find routines now returns the ID Cache Entry pointer
6273 as well if requested.
6275 * WHOIS command works now in router environment, tested with two
6276 routers, two servers and two clients.
6278 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6279 in router environment (as it is almost equivalent to WHOIS) but
6280 hasn't been tested thoroughly. Added new functions:
6282 silc_server_command_identify_parse
6283 silc_server_command_identify_send_reply
6284 silc_server_command_identify_from_client
6285 silc_server_command_identify_from_server
6287 * Disabled route cache adding because adding two different ID's with
6288 same IP replaces the old cache entry thus giving wrong route.
6289 The entry->router->connection is always the fastest route anyway
6290 so route cache may not be needed. Of course, new routes maybe
6291 established after receiving the ID when the entry->router->connection
6292 might not be anymore the most optimal.
6294 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6296 * Add route cache for received ID for fast routing.
6298 * Added silc_server_packet_route to route received packet on router
6299 that is not destined to us.
6301 * Renamed silc_server_get_route to silc_server_route_get.
6303 * Added id_string and id_string_len fields into SilcServer to
6304 include encoded ServerID for fast comparing without excess
6305 encoding of the ID's.
6307 * Cleaned up WHOIS command on server side. Added following static
6310 silc_server_command_whois_parse
6311 silc_server_command_whois_check
6312 silc_server_command_whois_send_reply
6313 silc_server_command_whois_from_client
6314 silc_server_command_whois_from_server
6316 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6317 arguments in command replies. All command functions should be
6318 updated to use this macro.
6320 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6322 * Minor typo fixes on command reply handling on server.
6324 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6326 * Added silc_server_command_add_to_channel internal routine to add
6327 the client to the channel after router has created the channel and
6328 sent command reply to the server.
6330 * Added generic silc_server_send_command to send any command from
6333 * Use static buffer with ID rendering instead of duplicating data.
6335 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6337 * Fixed a channel user mode bug when joining to a channel server gave
6338 everybody channel founder rights, oops.
6340 * We mark ourselves as the router of the incoming server connection
6341 if we are router ourselves. This way we can check in some packet
6342 sending functions whether it is locally connected server. For
6343 incoming router connections we put NULL.
6345 * For router sending packets locally means now always sending the
6346 packet cell wide; to local clients and local servers. For normal
6347 server sending packet locally means sending it to only local
6350 * Fixed the JOIN command to really work in router environment. If the
6351 channel is created it is always created by the router. Router is
6352 also responsible of making the initial joining to the channel,
6353 sending JOIN notify to the sending server and distributing
6354 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6355 does not exist server doesn't do anything else but forward the
6356 command to the router which performs everything.
6358 * Added silc_server_send_channel_key function to send the Channel Key
6361 * Added silc_server_create_channel_key to create new channel key. The
6362 channel key is now re-generated everytime someone joins or leaves
6363 a channel, as protocol dictates. Note: channel->key_len is the
6366 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6368 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6369 packet_receive.[ch] to separate packet sending and receiving
6370 routines. The server.[ch] now includes everything else including
6371 actual packet processing (writing and reading data) and other
6374 Renamed silc_server_private_message_send_internal to
6375 silc_server_send_private_message. The routine is still though
6376 used only to relay private messages as server does not send
6377 private messages itself.
6379 Renamed silc_server_new_channel to silc_server_create_new_channel
6380 and added new function sicl_server_new_channel that handles the
6381 incoming New Channel packet. Added also new sending function
6382 silc_server_send_new_channel to send New Channel Payload.
6384 * Added new function silc_server_notify to process incoming notify
6385 packet to the server/router. Server may then relay the notify
6386 to clients if needed.
6388 * Added new function silc_server_new_channel_user to process incoming
6389 New Channel User packet. Router will redistribute the packet and
6390 send JOIN notify to its local clients and locally connected servers
6391 if needed. Normal server will send JOIN notify to its local client
6392 on same channel when received this packet. Added also corresponding
6393 sending function silc_server_send_new_channel_user to sent the
6396 * Added boolean route argument to send_notif_to_channel and
6397 packet_send_to_channel functions to attempt to route the packet
6398 if it is TRUE and send only locally if it is FALSE.
6400 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6402 * silc_server_replace_id now broadcasts the received replace ID
6403 packet if it is not broadcast packet already. The router must
6404 broadcast to inform other routers about changed ID.
6406 * Added backpointer to server's router into SilcServer context in
6407 silcd/server_internal.h.
6409 * Fixed silc_server_packet_broadcast to send correct broadcast
6412 * The channel key is now distributed to the local client as soon
6413 as it is received from the router (in router environment) so that
6414 no other packet may be sent for the channel until client has
6417 * silc_server_remove_channel_user now broadcasts the received
6418 Remove Channel User packet if it is not broadcast packet already.
6419 The router must broadcast to inform other routers about removed
6422 * Added users field into SilcPacketContext that is a reference count
6423 of the context. One can increase the reference count by calling
6424 silc_packet_context_dup which is now changed to just increase the
6425 reference count instead of duplicating the data. The reference
6426 count is decresed by calling silc_packet_context_free that will
6427 free the data after the reference count hits zero.
6429 For now on the packet context and everything allocated into it
6430 (including the raw packet from network) must be freed by calling
6431 the new silc_packet_context_free function. Added also new function
6432 silc_packet_context_alloc that must be used now to allocate the
6433 context. This also means that if a routine is asynchronous from
6434 silc_[client/server]_packet_parse_type the packet context must
6435 be duplicated by calling silc_packet_context_dup. Otherwise it
6436 gets free'd after silc_[client/server]_packet_parse_type returns.
6437 Also, one must remember that if packet is duplicated then its
6438 reference count must be decresed by calling the free function as
6439 many times as it was duplicated.
6441 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6442 from both client and server.
6444 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6446 * Made joining to a channel working in router environment.
6448 * Cleaned up JOIN command on server side and create function
6449 silc_server_command_join_channel internal routine to make the
6452 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6454 * Changed silc_command_pending list to SilcDList. Also, added
6455 `ident' field to SilcServerCommandPending structure to identify
6456 the reply and to call correct callback.
6458 Added silc_server_command_pending_check function to replace the
6459 corresnponding macro. The silc_command_pending list is not
6462 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6463 to set identifier to previously allocated Command Payload. It
6464 is used to set identifier for command when resending Command
6467 * Added silc_command_payload_encode_payload to encode Command
6468 Payload buffer from SilcCommandPayload structure.
6470 * Added silc_argument_payload_encode_payload to encode Argument
6471 payload buffer from SilcArgumentPayload structure.
6473 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6475 * Changed WHOIS command to support router connection on server side.
6476 The whois request is always sent to router unless the server is
6477 standalone server. After server has received the reply from the
6478 router will it send the reply to the client.
6480 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6481 broadcast received broadcast packet. The function is used only
6482 by router. The broadcast packet is always sent to the router's
6485 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6486 render given ID to printable string, for log files for example.
6488 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6490 * Made basic router to router connections working. At least they
6491 can now connect to each other but nothing really works the way
6492 they are supposed - yet.
6494 * Added new initiator token to RouterConnection configuration
6495 file in silcd/serverconfig.[ch]. It is used to tell whether we
6496 are the initiator to the remote router or whether we'll expect
6497 the other end to connect.
6499 * Moved registering of listener task to silc_server_init, hence
6500 the server starts listenning as soon as it is run, even if it
6501 does not have connections to other routers. Let's see how well
6504 * Changed default connection retry timeouts for more suitable in
6507 * Removed cipher and such arguments from silc_idlist_add_client
6508 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6509 Added new function silc_idlist_add_data to add the keys and stuff
6512 * Added SilcIDListData structure and added it to SilcClientEntry
6513 and SilcServerEntry as their first field in the structure. This
6514 way we can explicitly cast the ID entries to the SilcIDListData
6515 structure and get common data for the entries. In past, we had
6516 to first check what type of connection it is and then cast it to
6517 correct ID entry type. Now, we can directly cast the opaque
6518 pointer to the SilcIDListData (no matter what ID entry it actually
6519 is) and get the data needed.
6521 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6523 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6524 in some circumstances even if threre were timeout tasks, though not
6525 IO tasks, but tasks anyway. Now fixed.
6527 * Defined SilcServerConnection structure to hold connection specific
6528 stuff about directly connected servers and routers. The definition
6529 is currently in silcd/server_internal.h. I thought about having
6530 a bit more important role fro this struct but for now it is used
6531 only when connecting to other server (or router actually).
6533 * Added connecting retry support in server when connecting to
6534 router(s). The retry feature implement exponential backoff
6535 algorithm. Also, added SilcServerParams structure to hold default
6536 parameters for server. For now, it include these retry settings
6537 and are hard coded. After server is moded to be as Silc Server
6538 Library this structure will be more important.
6540 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6542 * Changed client librarys channel->clients table to SilcList and
6543 changed code accordingly.
6545 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6547 * Changed client's channel table to SilcList and changed code
6548 accordingly. Also changed SilcChannelClientEntry to include back-
6549 pointer to the channel so that client entry can use that structure
6550 as list as well and we have fast cross-reference to the channel.
6551 This change dramatically decreased the complexity of channel
6552 handling with client entry and vice versa (removed one extra
6553 loop when searching for channel entry from many functions).
6555 * Changed server->sim from table to SilcDList and changed code
6558 * NAMES command can now be used from user interface. It will show
6559 the user list on the channel, neatly.
6561 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6562 Code now saves realname of the user if it becomes available.
6564 * Renamed configure.in to configure.in.pre and made ./prepare
6565 script to automatically add correct version string to
6566 configure.in which it creates from configure.in.pre.
6568 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6570 * NAMES command reply now shows users mode with the nickname when
6573 * Moved silc_client_ch[u]mode[_char] functions from
6574 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6575 place sucks, they are utility functions and should be in some
6578 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6580 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6583 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6587 * Added TRQ (efficient deque and list library) into lib/trq. This is
6588 a very good list library that is currently used in the SILC. Defined
6589 SilcList API over the library because I didn't like the API very
6590 much. See lib/trq/silclist.h for the API and examples of how to
6591 use the API. Fixed various places in the code to use the new
6592 SilcList API. The SilcList is meant for lists that has a structure
6593 already defined as a list. It is not suitable to add just some
6594 context to the list (in TRQ, the context is the list actually).
6596 So, I defined SilcDList that can be used for the purpose where
6597 predefined list structure does not exit. This can be used as
6598 such list. Now some context just can be added to the SilcDList.
6599 Currently this list is not used in the SILC just yet, though there
6600 are a lot places where this can replace dynamically allocated
6601 tables and I will fix these places, later, to use SilcDList.
6602 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6603 and use TRQ internally).
6605 Also fixed some annoying warning messages that the original TRQ
6606 code generated. Also minor changes to TRQ's Makefile.in.
6608 * Added support for querying by Client ID to both WHOIS and
6609 IDENTIFY commands into server, as required by the protocol.
6611 * Removed method function pointers from SilcBuffer structure. They
6612 weren't used to anything and just increased the context size for
6613 no good reason. This change also made silc_buffer_alloc and
6614 silc_buffer_free functions inline functions.
6616 * Disabled command flooding detection support until it's fixed so
6617 that it accepts commands in but does not execute them more than once
6620 * Added silc_net_localhost(), to return local hostname, into
6621 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6622 that must be initialized before calling silc_client_init.
6624 * Added new function: silc_server_send_notify_on_channels to send
6625 notify messages to all channels client has joined. It is assured
6626 that the message is sent only once per client.
6628 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6629 lib/silcutil/silcutil.[ch] as silc_format function. The new
6630 function is generic and is used by server as well, not only by
6631 the logging routines.
6633 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6634 the provided version string was not acceptable. Added new function:
6635 silc_ske_check_version into lib/silcske/silcske.h. The function
6636 must be implemented by the application (client or server) and it
6637 does not reside in the SKE library. The function checks the version
6638 string remote end sent.
6640 * Added back pointers (to opaque context and to SilcSocketConnection)
6641 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6643 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6644 duplicate packet context structure.
6646 * Changed `notify' client operation to send same arguments as client
6647 receives from server except for ID's. ID's are mapped to correct
6648 ID entry and that is returned. Also, if channel entry is not sent
6649 by server but the notify is for channel the channel entry is sent
6650 to application (otherwise application doesn't know that it is for
6651 channel (library gets it from packet's Destination ID)).
6653 * Added silc_client_remove_from_channels into client library to
6654 remove a client from all channels it has joined to. Used when
6655 received SIGNOFF notify from server. Added also new function
6656 silc_client_replace_from_channels to replace old ID entry with
6657 new ID entry on all channels. Used when received NICK_CHANGE
6660 * Fixed ID Cache list handling in silc_idlist_get_client in
6661 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6662 to get (or query) client by ID.
6664 * Updated TODO list.
6666 * Added connection authentication status message defined by the
6667 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6668 support for these into the code in client and server side.
6670 * Added generic function silc_client_send_command to send any command
6671 with variable argument list. Application should use this function
6672 to send commands if the command functions provided by the library
6673 does not suite for the application's user interface needs.
6675 * Added new `failure' client operation. Application is notified about
6676 received failure packet if client is executing a protocol. In this
6677 case the protocol's execution has failed.
6679 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6680 is required by the protocol.
6682 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6683 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6686 * Added status flag to SilcSKE object to indicate realtime status
6687 of the SKE protocol.
6689 * Application receives now exactly same command reply arguments as
6690 the library receives from server. However, if ID is received the
6691 corresponding ID entry is returned to the application (eg. Client
6692 ID is mapped to correct SilcClientEntry entry and that is returned).
6693 Changed command_reply client operation due to this change.
6695 * Changed all ID's in commands and in command replys as ID Payloads.
6696 Change affected both client and server side codes.
6698 All ID's sent in SILC network (with execption of ID's in SILC
6699 Packet header) are sent in ID Payload to support variable length
6702 * Server now notifies nick changes and notifies all clients on
6703 the channels about the new nickname (about the new Client ID,
6706 * Implemented CMODE command to change channel modes. Supports all
6707 channel modes defined by the protocol specs except ban and invite
6708 lists. (Also, private channel key mode is supported but support for
6709 setting private channel key in client is missing, thus, this mode
6710 has no effect on client side (except that server requires that the
6711 client uses private channel key and normal channel traffic does not
6714 Also, invite mode works per se, but INVITE command does not work
6715 yet correctly, so you can set channel as invite only channel but
6716 inviting clients to the channel does not work (it is yet to be
6717 thought what's the best way to do it).
6719 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6720 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6721 Implemented CUMODE command to change user's mode on the channel.
6722 Supports all modes defined by the protocol specs.
6724 * Added NAMES command reply to return users modes on the channel.
6726 * Removed unnecessary and slow ciphers from lib/silccrypt.
6728 * Set SO_KEEPALIVE option to connection sockets by default.
6730 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6732 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6733 redefined the Notify Payload into protocol specs.
6735 * Added silc_id_payload_parse_id to get ID directly from raw
6738 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6740 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6741 accept searching by Client ID as well.
6743 * Added support for LEAVE and SIGNOFF notify types in client library.
6745 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6746 to parse ID Payload from raw data.
6748 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6750 * Added flags parameter into silc_ske_assemble_security_properties
6751 function in lib/silcske/silcske.[ch].
6753 * Changed notify client operation to fit better for notify messages
6754 sent by server. The notify payload received from server is now
6755 passed to the application (after parsing it to SilcNotifyPayload).
6756 It is application's responsibility to retrieve the arguments
6757 from the payload and show the message the way it wants. The message
6758 sent by server is implementation specific.
6760 * Changed public keys to comply with the protocol specification.
6761 Old public keys are not supported anymore and are not compatible.
6763 * Removed nickname from Channel Payload as the latest draft removed
6764 it. The client must resolve the nickname from the NAMES command
6765 reply received when it joined the channel.
6767 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6769 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6771 * Fixed some errors in protocol specification drafts.
6773 * Created lib/silccore/silcnotify.c to implement Notify Payload
6774 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6775 generic payloads described by protocol specifications. The file
6776 includes implementations for ID Payload and Argument Payload.
6778 * Changed Command Payload implementation to use the new Argument
6779 Payload. Changed command_xxxx_payload to command_payload_xxxx
6780 to comply with SILC coding conventions.
6782 * Added suppport for Argument Payload handling in Notify Payload
6783 implementation as protocol requires it. Added the new support
6784 into server and client lib as well.
6786 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6788 * Added support for multiple nicknames on same channel. [n] is
6789 added locally to the nickname if there are more than one same
6790 nicknames on the channel.
6792 * Server now sends all nicknames that matched WHOIS request.
6793 Client also shows the list received from server.
6795 * Added TOPIC command to client side. User can now set and show
6796 current topic on channel.
6798 * Added MOTD command to client and server. Also, server sends the
6799 motd when client connects to the server.
6801 * Changed version strings to comply ISO 8601.
6803 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6805 * Fixed protocol error handling in client library. It should now
6806 cope even if the SKE fails for some reason.
6808 * Made new protocol specification drafts for submitting to IETF.
6810 * Implemented TOPIC command to server in silcd/command.c.
6812 * Added two new notify types into lib/silccore/silcnotify.h:
6813 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6814 notify nickname change and topic setting/change on a channel.
6816 * API change of command_reply operation in client library. The
6817 application gets now the status type received from server as well.
6819 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6821 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6823 * Cras fixed and optimized the packet handling even further and
6824 it should work now. Minor change to the prototype of function
6825 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6827 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6829 * Added new function into lib/silcutil/silcschedule.[ch]:
6830 silc_schedule_with_fd to select() a specified fd. The function
6831 returns after timeout expires or data arrives or goes. The
6832 function is used by packet routines to wait that all data is
6833 received from network.
6835 * Fixed data reading from network in lib/silccore/silcpacket.c.
6836 The code now assures that all data is read from the fd and then
6837 continues packet processing. This was a bug fix since the code
6838 used to drop some data in some circumstances.
6840 * Added new function into lib/silcclient/client.[ch]:
6841 silc_client_start_key_exchange to start key exchange after
6842 connection has been established to server. The code internally
6843 now uses this funtion but its main purpose was to provide it
6844 for applications that perform their own connecting. After
6845 application has created a connection it merely calls this
6846 function to start the key exchange between client and server.
6847 The library takes care of everything else after that.
6849 Updated also lib/silcclient/README to explain the usage of
6852 * Do not send to application information that connection has
6853 been established. Application gets notified it by connect
6856 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6858 * Applied cras's patch to add silc_schedule_one function. The
6859 function runs scheduler once and returns.
6861 * Fixed the scheduler after cras messed it up. The timeout
6862 handling works now as it's supposed to work.
6864 * Added into lib/silccore/ silcnotify.h to include notify
6865 message types support. Changed silc_server_send_notify*
6866 functions, in server.[ch], to support those new notify types.
6867 Added the support for the notify types into client library,
6868 as well. Added new notify client operation into ops.h in
6871 * Changed silc_server_packet_send_to_channel to send normal
6872 packets instead of just channel message packets. The function
6873 is now used to send the notify packets to channels. It is not
6874 used to send channel message packets anymore, as server never
6877 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6878 va_arg()s as it seems to require it nowadays. I guess, if SILC
6879 is compiled with older va_arg() the new code should work anyway.
6881 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6883 * Splitted core library. Core library (lib/silccore) includes
6884 now only SILC protocol specific core (and common) components.
6885 Created new utility library (lib/silcutil) that includes more
6886 generic purpose stuff. The stuff for util library was taken
6887 from the old core library. This was minor and easy split.
6889 * Created SILC Client Library (lib/silcclient) that includes
6890 implementation of the SILC client without user interface. This
6891 was major move from silc/ directory. The code has been changed
6892 so that it is transparent towards the user interface. The
6893 silc/ directory includes now the same user interface as before
6894 and it uses the new client library. Read lib/silcclient/README.
6895 Basicly, the client library performs everything else related
6896 to SILC except user interface handling. Also, configuration
6897 files are considered to be part of user interface and library
6898 does not handle them.
6900 This change also changed a lot of structures, function naming etc.
6901 Most important change was that SilcClientWindow object was
6902 renamed to SilcClientConnection in the client library. Created
6903 also new file lib/silcclient/ops.h. Also added new files
6904 silc/local_command.[ch] and silc/client_ops.[ch].
6906 All these changes were made to make it easier for user interface
6907 designers to create what ever user interface for the SILC client
6910 It is also expected that the server will be moved to lib
6911 directory as well and SILC Server Library will be created;
6912 sometimes in the future.
6914 * Removed Local commands from lib/silccore/silccommand.h as
6915 they are application specific and new client library does not
6916 handle any of those anymore.
6918 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6919 old client implementation in silc/.
6921 * Added support for callback functions in SILC_LOG_* macros.
6922 Application can now set its own callbacks that will be called
6923 instead of using the default functions that will always print
6924 the debug messages to stderr (or stdout). Also, debugging can
6925 now be disabled by setting silc_debug to FALSE and re-enabled by
6926 setting it to TRUE. Note, that logging will still work even
6927 if debugging is disabled.
6929 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6930 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6931 silc_log_reset_debug_callbacks.
6933 * To enable debugging in silc client one must give now -d
6934 option on command line.
6936 * Changed silc_schedule_init to automatically allocate task queues
6937 if they are not allocated before calling it.
6939 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6941 * Added GMP 3.1 into math library.
6943 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6945 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6946 a channel in SILC network. The packet is used by servers and
6947 routers to notify other routers that user has left a channel.
6948 This little feature was missing until now. Added the feature
6949 to protocol specification as well.
6951 Added functions: silc_server_send_remove_channel_user and
6952 silc_server_remove_channel_user into server.[ch].
6954 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6955 lib/silccore/silcpacket.h. However, they are not implemented
6958 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6960 * Fixed joining to a channel and sending channel messages
6961 between server and router. The channel message sending should
6962 now work inside a cell.
6964 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6966 * Fixed the private message sending between server and router.
6967 The private message sending should now work inside a cell.
6969 * Added silc_server_replace_id into server.[ch] to replace
6970 existing ID in the SILC network.
6972 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6973 and silc_idlist_replace_server_id into idlist.[ch] in server.
6975 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6977 * Fixed the server to server connections. Server can again now
6978 connect to router. Router to router connections probably does
6981 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6983 * Added dynamic protocol registering support. Now protocols can
6984 registered and unregistered on the fly. Patch by cras.
6986 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6988 * Added lib/contrib directory to hold routines that some platforms
6989 don't have but are needed by SILC.
6991 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6992 into lin/contrib to provide getopt() and getopt_long() for
6993 those who don't have it.
6995 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6997 * Added AWAY command to client. When away message is set and
6998 client receives a private message packet the client automatically
6999 replies to the sender with the away message.
7001 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7002 bug seemed to be the cause of recent problems when compiling
7005 * Added version detection support to SKE protocol specification
7006 and added the new changes to the SKE implementation as well.
7007 There were other minor changes in the SKE protocol as well.
7009 Many changes in lib/silcske/silcske.[ch] and in
7010 lib/silcske/payload.[ch].
7012 * Added ^U functionality, clear input line. Patch from cras.
7014 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7016 * Mainly small bugfixes on core library. Fixed some debugging
7017 logging and buffer overflow in silclog.c.
7019 * Updated config.sub and config.guess on the distribution tree.
7021 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7023 * Added command lagging support in server. Client may execute
7024 commands now only once in two seconds.
7026 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7028 * Optimized packet reception. MAC computation and checking is now
7029 also more optimized. A lot previously duplicated code is now
7030 used as generic by both client and server.
7032 * Fixed key pair generation in clientutil.c
7034 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7036 * Added into lib/silccore/silcbufutil.[ch] new function;
7037 silc_buffer_realloc.
7039 * Moved generic packet sending/encryption functions to
7040 lib/silccore/silcpacket.[ch] from client and server. Some
7041 rewriting of the functions.
7043 * Moved all generic packet reception/decryption functions to
7044 lib/silccore/silcpacket.[ch] from client and server. The
7045 packet processing is now much cleaner in both client and server.
7046 These were major changes in both client and server.
7048 * Created many common functions in server to do packet sending.
7049 Previously code were duplicated a lot, this has been removed
7052 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7054 * Rewrote major parts of the ID cache system. Don't know
7055 whether it is better now or not but at least the API is more
7058 * Major rewrite on ID cache stuff on client because of the ID
7059 cache API changes. Added idlist.c to client.
7061 * Also major rewrite on ID cache stuff on server as well.
7062 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7063 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7064 in hand, instead they are all put into the ID cache system now.
7065 All server_idlist_* routines uses ID cache now instead of
7066 traversing its own lists (those lists does not exist anymore).
7067 SilcIDList though still exists. Also, SilcXXXEntry's are
7070 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7072 * Finally made the SKE implementation compliant to the protocol
7073 specification. All mp integers are now binary encoded as
7074 opposed being HEX encoded.
7076 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7079 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7080 functions: silc_[encode/decode]_pem. Also added function
7081 silc_encode_pem_file to PEM encode with newlines ('\n') for
7084 * SILC public keys are now encoded either PEM or binary. Same
7085 option is for private keys as well. By default private keys
7086 are binary encoded and public keys PEM encoded. Silly HEX
7087 encoding were removed.
7089 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7090 function to create fingerprints.
7092 * Fixed a bug in SHA1; does not change the original data anymore.
7094 * Partly implemented INFO command on client and server side.
7095 Fixed CLEAR command. Changes to SERVER command; show current
7096 server(s) when giving command without arguments. Added
7097 VERSION command to client.
7099 * Added check to server that unregistered connections cannot
7100 execute commands (unless it is specificly allowed).
7102 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7104 * Fixed screen refresh.
7106 * Fixed channel joining bug from client. On some circumstances
7107 client tried to join to a channel it had already joined.
7109 * Added public key verification process into client's protocol.c.
7110 The client now verifies the public key from user and saves
7111 it into ~./silc/serverkeys/ directory.
7113 Added into: clientutil.[ch]: silc_client_verify_server_key.
7115 * Changed SKE protocol's silc_ske_initiator_finish function
7116 to accept callback function that verifies the received public
7117 key. Removed old silc_ske_verify_public_key function.
7119 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7121 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7122 silc_pkcs_private_key[_data]_set.
7124 * Made the password and public authentication more cleaner in
7125 server's protocol.c.
7127 * Removed historic and obsolete protocol `channel_auth' from
7128 both client and server.
7130 * Removed wrong way of sending command status messages from
7131 server to client in server's command.c. The old way violated
7132 protocol specification.
7134 Changes to silccore/silccommand.[ch]: removed
7135 silc_command_encode_status_payload -> not needed anymore,
7136 changed silc_command_encode_payload_va to accept extra
7137 argument on variable argument list. The argument type must
7138 now be provided to the function. Also, added new function:
7139 silc_command_encode_reply_payload_va which is same as
7140 normal command_encode_payload_va except command status type
7141 is provided as extra argument.
7143 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7145 * Added ~./silc directory handling. The directory includes the
7146 public and private keys for the client.
7148 Added silc_client_check_silc_dir, silc_client_create_identifier
7149 and silc_client_load_keys.
7151 * Implemented SILC protocol compliant public key. Added public
7152 and private key saving to and loading from files.
7154 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7155 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7156 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7157 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7158 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7160 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7161 silc_pkcs_load_[public/private]_key.
7163 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7165 * Added silc_server_get_route (route.[ch]) to get connection
7166 data for the fastest route for given ID.
7168 * Implemented INVITE command on client and server. The command
7169 were re-defined in the SILC Protocol Specification and the
7170 implementation now complies with the specification.
7172 * Implemented PING command on client and server.
7174 * Implemented NAMES command on client and server. The server side
7175 supports currently only normal server not router server yet.
7176 Some changes to NAMES definition in SILC protocol specification.
7178 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7180 * Implemented LEAVE command on client and server.
7182 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7183 again. This change was made to the protocol as well. Server
7184 should not violate the protocol specification anymore.
7186 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7188 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7189 was tested. SOCKS4 was not but should work anyway.
