58 whether given configuration value has been given already.
60 Affected files silcd/serverconfig.[c], server.[c].
62 * Splitted the doc/example_silcd.conf.in. Separated the crypto
63 algorithm parts and created new file silcalgs.conf, that
64 is now included from the example_silcd.conf.in.
66 * Optimized the silc_server_connect_to_router_second to take
67 the connection configuration object from the SilcServerConnection
68 object instead of finding it during the connecting phase.

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

150 hash algorithm. Affected file lib/silccrypt/silcrng.c.
152 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
154 * Fixed the file transfer's key agreement payload to include
155 zero port also if the hostname is NULL because it could not
158 Call file transfer monitor callback now also if error occurs
159 during key agreement protocol.
161 Changed the silc_client_file_send interface to return the
162 SilcClientFileError instead of session id. The session ID
163 is returned into pointer provided as argument.
165 Check that the file exists locally before sending the
166 file transfer request at all.
168 Affected file lib/silcclient/client_ftp.c, silcapi.h.

180 file lib/silcutil/silclog.c.
182 * Fixed the channel message payload decryption in the function
183 silc_channel_message_payload_decrypt to not modify the original
184 buffer before it is verified that the message decrypted
185 correctly. Otherwise, next time it is called with correct
186 channel key it won't encrypt since the payload is corrupted.
187 Affected file lib/silccore/silcchannel.c.
189 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

201 * Fixed a bug in hash table internal routine for traversing
202 the table with foreach callback. The current entry may
203 become invalid in the callback but it was referenced after
204 the callback returned.
206 Do not allow auto rehashing of hash table during the
207 silc_hash_table_foreach operation, for same reasons as it is
208 not allowed for SilcHashTableList. Affected files are
209 lib/silcutil/silchashtable.[ch].
211 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
213 * Defined DLLAPI into silcincludes.h and silcwin32.h for

217 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
219 * Fixed private message handling. It used some old code that
220 caused the client to crash. Affecte file is
221 lib/silcclient/client_prvmsg.c.
223 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
225 * Added function silc_client_add_channel,
226 silc_client_replace_channel_id, and removed functions
227 silc_client_new_channel_id and silc_idlist_get_channel_by_id
230 * Added cross reference of the joined channels to the
231 SilcClientEntry, and changed the SilcChannelEntry's
232 users list to SilcHashTable. The affected files are
233 lib/silcclient/idlist.[ch].
235 * Fixed a bug in hash table tarversing. While the hash table
236 is traversed with SilcHashTableList the table must not be
237 rehashed. It is now guaranteed that auto rehashable tables
238 are not rehashed while tarversing the list. Also defined that
239 silc_hash_table_rehash must not be called while tarversing
240 the table. Added function silc_hash_table_list_reset that must
241 be called after the tarversing is over. The affected files are
242 lib/silcutil/silchashtable.[ch].
244 * Changed all hash table traversing to call the new
245 silc_hash_table_list_reset in server and in client library.
247 * Added function silc_client_on_channel to return the
248 SilcChannelUser entry if the specified client entry is joined
249 on the specified channel. This is exported to application as
250 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
252 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
254 * Fixed founder regaining problem with JOIN command on normal
255 server. The notify for mode change must be sent always and
256 not only if !cmd->pending. Affected file silcd/command.c.
258 * Fixed the WHOWAS command's reply sending to support the
259 lists correctly. Affected file silcd/command.c.
261 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
263 * When sending JOIN command to router for processing the
264 sender's old command identifier was not saved back to the
265 sender's command context, fixed now. The affected file is
268 * Create the key in JOIN command of the router did not return
269 the channel key, added check for this. Affected file is
272 * Fixed a channel ID update bug in JOIN command reply. Do
273 not directly upgrade the ID but call the function
274 silc_idlist_replace_channel_id if the ID was changed.
275 Affected file silcd/command_reply.c.
277 * Fixed memory leaks from command calling if it would fail.
278 Affected file silcd/command.c.

285 new silclist.h and silcdlist.h, all extern inline changed to
288 * Removed dotconf from lib/dotconf, not needed anymore.
290 * Removed TRQ from lib/trq, not needed anymore.
292 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
293 with server connections. Later this will be configurable
294 in config file after new config file is done. Affected file
297 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
299 * Fixed a crash in server related to channel announcements.
300 Affected file silcd/server.c.
302 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
304 * Fixed memory leaks in silc_server_create_new_channel*
305 functions. Affected file silcd/server.c.
307 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
308 which ID was changed. This way the router will send the
309 user list for the channel again, and server won't be in
310 desync in some rare circumstances. Affected file is
311 silcd/packet_receive.c.
313 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
315 * Check for NULL socket pointer in the function

324 * Fixed some header addition to Toolkit distribution in
325 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
327 * Added lib/silcclient/client_ops_example.h as an template
328 file for application programmers to quickly start using
329 the SilcClientOperation functions in their application.
330 Updated the lib/silcclient/README as well to tell about this
331 nice file made available.
333 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
335 * Call silc_server_remove_from_channels when removing client
336 entry when NO_SUCH_CLIENT_ID was received. Affected file
337 is silcd/command_reply.c.
339 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
341 * Added server & router operator statistics updating. Affected
342 file silcd/packet_receive.c and silcd/command.c.
344 * Fixed the SERVER_SIGNOFF notify handling on normal server
345 not to save the history information for clients. Same was
346 fixed earlier in remove_clients_by_server function, but not
347 here. Affected file silcd/packet_receive.c.
349 * Raised the default connection-retry count from 4 to 7 in
350 server. Affected file silcd/server.h.
352 * Cancel any possible reconnect timeouts when we start the
353 key exchange. Affected file silcd/server.c.
355 * Do not reconnect on connection failure when SCONNECT was
356 given. Affected files silcd/server.[ch].
358 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
360 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
362 * Fixed the NICK command to always give the unformatted
363 nickname to the one giving the NICK command. If unformatted
364 nickname is cached already it will be formatted and the
365 local entry will always get the unformatted nickname.
366 Affected file lib/silcclient/idlist.c.
368 * Fixed some double frees from client library commands.
369 Affected file is lib/silcclient/command.c.
371 * Fixed CUMODE command in server to assure that no one can
372 change founder's mode than the founder itself, there was a
373 little bug. Affected file silcd/command.c.
375 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
377 * Removed the SilcClientCommandDestructor from the client
378 libary, it is not needed anymore. Affected files are
379 lib/silcclient/silcapi.h, command[_reply].[ch],
380 client_notify, idlist.c.
382 * Fixed GETKEY command to first resolve client, and then
383 resolve the server only if the client was not found, instead
384 of resolving both at the same time. Affected file is
385 lib/silcclient/command.c.
387 * Added silc_client_start_key_exchange_cb and lookup the
388 remote hostname and IP address before starting the key
389 exchange with server. The affected file is
390 lib/silcclient/client.c.
392 * The server's public key is now saved using the IP address
393 of the server and not the servername for the filename.
394 The hostname public key filename is checked as an fall back
395 method if the IP address based filename is not found.
397 Fixed the GETKEY command to save the fetched server key
400 Print the remote server's hostname now when new key is
401 received during connection process. Affected file is
402 irssi/src/silc/core/client_ops.c.
404 * Return always our own public key to the client if it asks
405 for it with GETKEY command. Affected file silcd/command.c.
407 * Removed the use_auto_addr variable from default config
408 file since it was in wrong section. Affected file is
411 * Fixed TOPIC_CHANGE notification to not route it when it
412 was sent using silc_server_send_notify_to_channel function.
413 Affected file silcd/command.c.
415 * Fixed silc_server_send_notify_kicked to send the kicker's
416 Client ID also, it was missing. Affected files are
417 silcd/command.c, silcd/packet_send.[ch].
419 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
421 * Do not save client history information in SERVER_SIGNOFF.
422 Fixes the bug in normal server that it does not detect
423 the client becoming valid after the server becomes back
424 online. Affected file silcd/server_util.c.
426 * Added `sock_error' field into the SilcSocketConnection
427 context. When error occurs during socket operation (read
428 or write) the error is saved. Added also new function
429 silc_socket_get_error to return human readable socket error
430 message. Affected files are lib/silcutil/silcsockconn.[ch],
431 lib/silcutil/unix/silcunixsockconn.c, and
432 lib/silcutil/win32/silcwin32sockconn.c.
434 * The server now prints the socket error message in the
435 signoff for client. Affected file silcd/server.c.
437 * Fixed the `created' channel information sending from router
438 to server in JOIN command. Checks now whether the channel
439 really was created or not and set it according that.
441 Fixed the JOIN command to use the client entry's current
442 ID during the joining procedure instead of the one it sent
443 in the command (it is checked though), since it can change
444 between the packet processing and command processing, and
445 would just case unnecessary pain in the client end. Affected
446 file silcd/command.c.
448 * Fixed a channel key payload sending to use correct channel
449 ID when the server was forced to change the channel's ID by
450 router. Router sent the key payload with the old Channel ID.
451 Affected file silcd/packet_receive.c.
453 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
455 * Call silc_server_save_channel_key only if the key payload
456 was provided in the JOIN command's command reply. Affected
457 file silcd/command_reply.c.
459 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
461 * Fixed silc_mp_sizeinbase to return the value correctly with
462 MPI. Affected file lib/silcmath/mp_mpi.c.
464 * Fixed the stop_server signal to correctly stop the scheduler
465 and gracefully stop the server when SIGTERM or SIGINT signals
466 are received. Affected file silcd/silcd.c.
468 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
470 * Simple handling of TERM and HUP signals. Also added some log
471 flushing call around. Affected file is
474 * Fixed small bugs in silclog.c. Now buffering output will take
475 effect after 10 seconds since startup: This will ensure that
476 no important startup messages are lost. Also output redirection
477 will preserve original format ([Date] [Type] message).
478 Affected file is lib/silcutil/silclog.c.
480 * Added two options to the config file, in the logging section:
481 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
482 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
484 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
486 * Do not print the warning about log files not being initialized
487 more than once to avoid excess logging. Affected file is
488 lib/silcutil/silclog.c.
490 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
491 the SIM copying in make install in Makefile.am.pre.
493 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
495 * Rewritten silclog APIs. Globally interesting changes follows:
496 silc_log_set_files() changed to silc_log_set_file().
497 silc_log_set_callbacks() changed to silc_log_set_callback().
498 ROBOdoc documented silclog header file.
499 SilcLogCb now returns bool to wether inihibit the default
500 handler or not (to keep the old behaviour return always TRUE).
501 The new APIs should also fix the problem of the
502 silcd_error.log file that was written in the current directory.
505 Log files streams will remain opened after silc_log_set_file()
506 call, means less CPU usage notably on high traffic servers.
507 File streams are now full buffered, and flushed to the disk
508 every 5 minutes, lesses HD activity and CPU usage.
509 Messages can be redirected, allowing admins to configure
510 one single logfile for all server messages.
511 the silc_log_quick global variable to activate fast-logging.
512 Affected files lib/silcutil/silclog.[ch]
514 * Changed some code to conform new silclog APIs. Affected
515 files are doc/example_silcd.conf.in, silcd/server.c
516 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
519 * Fixed a memory leak that could occur in some situations.
520 Affected file silcd/serverconfig.c.
522 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
524 * Added the silc_client_del_client to remove the client from
525 all channels as well. Affected file lib/silcclient/idlist.c.
527 * Fixed the client library to correctly remove the client
528 from all channels when the client entry is being destroyed.
529 Affected file lib/silcclient/client_notify.c, command.c.
531 * Added auto-nicking support to the client library. If the
532 applicatio now sets client->nickname it will be sent to the
533 server after connecting by the library. This way for example
534 SILCNICK (or IRCNICK) environment variables will have effect
535 and always change the nickname automatically to whatever
536 it is wanted. Affected file lib/silcclient/client.[ch].
538 * Renamed silc_server_command_bad_chars to the
539 silc_server_name_bad_chars and moved it to the
540 silcd/server_util.[ch]. Added also new function
541 silc_server_name_modify_bad to return nickname that
542 includes bad characters as new nickname without those
543 bad characters. This check and modify is now used in
544 silc_server_new_client when the username is initially set
545 as nickname, so it must be checked to be valid nickname.
546 Affected file silcd/packet_receive.c.
548 * The nickname length is now taken from the packet for real
549 and not trusted to strlen() since it clearly can return
550 wrong length for nickname including bad characters. This
551 also applies to channel names. Affected file silcd/command.c.
553 * Removed the lib/silcsilm/modules directory. Modules are now
554 compiled into the lib/silcsim. Fixed the copying of the
555 modules to follow symbolic links in Makefile.am.pre.
557 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
559 * Fixed silc_string_regexify list creation. Fixes bugs with
560 BAN and INVITE commands in server. The affected file is
561 lib/silcutil/unix/silcunixutil.c.
563 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
565 * Removed the command destructor entirely from the server's
566 command and command reply routines. It is not needed, and
567 its usage was buggy and caused crashes. Affected files are
568 silcd/command[_reply].[ch].
570 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
572 * Cancel protocol and NULL sock->protocol if timeout
573 occurred during protocol. Affected file silcd/server.c.
575 * Cancel protocol timeouts always before calling the final
576 callback, to assure that after final callback is called
577 no other state will be called for the protocol anymore.
578 Affected file silcd/protocol.c.
580 * Print error log if incoming connection configuration could
581 not be found. Affected file silcd/server.c.
583 * Fixed JOIN command to correctly save the founder mode
584 to the client on normal SILC server, when the channel
585 was created by the router. Affected file silcd/command.c.
587 * Fixed LIST command (hopefully) to send correct reply
588 packets. Affected file silcd/command.c.
590 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
592 * The silc_packet_receive_process now returns FALSE if the
593 read data was invalid packet, and TRUE if it was ok.
595 The server now checks that if unauthenticated connection
596 sends data and its processing fails the server will close
597 the connection since it could be a malicious flooder.
599 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
601 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
603 * Make sure the warning about error opening a log file is
604 printed only once and not everytime it fails (produces
605 too much useless log). Affected file lib/silcutil/silclog.c.
607 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
609 * Made the silc_server_daemonise() function more readable.
610 Affected file silcd/server.c.
612 * Pid file is now optional, the user may comment it out from
613 the config file. Removed define SILC_SERVER_PID_FILE, we
614 don't need a default any longer. Affected file
615 configure.in.pre, lib/Makefile.am.pre.
617 * Make some use of the pid file. The server now dies at startup
618 if it detects a valid pid file on his path. The server would
619 die anyway in this circumstance, because of the bind() failure.
620 Affected file silcd/silcd.c.
622 * No longer compiling lib/dotconf.
624 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
626 * Fixed JOIN command parsing not to crash. Affected file
627 lib/silcclient/command.c.
629 * Fied the NICK_CHANGE notify to add the new client entry
630 even it is resolved. This removes an <[unknown]> nick
631 thingy bug in the client. Affected file is
632 lib/silcclient/client_notify.c.
634 * Do not try to allocate 0 bytes (efence does not like it)
635 in lib/silccore/silccomand.c when encoding payload.
637 * Do not take IRCNICK as nickname in Irssi SILC client since
638 it is not possible to set nickname before hand connecting
639 the server (TODO has an entry about adding auto-nicking
642 * Changed the silc_server_command_pending to check whether
643 there already exists an pending entry with the specified
644 command, command identifier and pending callback. This is
645 to fix IDENTIFY and WHOIS related crashes that may register
646 multiple pending commands with same identifier. Affected
647 file silcd/command.c.
649 * Fixed the server to reconnect to the router even if it
650 was already reconnecting and EOF was received. This to
651 fix a possibility that the server wouldn't ever try to
652 auto-reconnect to the router. Affected file silcd/server.c.
654 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
656 * Fixed the server's password authentication to use the
657 length of the locally saved password, and not the one
658 sent in the packet. Affected file silcd/protocol.c.
660 * Fixed same password authentication problem in the
661 Authentication Payload handling routines in
662 lib/silccore/silcauth.c.
664 * Yet another password authentication problem fixed with
665 channel password handling in silcd/command.c.
667 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
669 * If first character of string in silc_parse_userfqdn is '@'
670 then do not parse it. Affected file is
671 lib/silcutil/silcutil.c.
673 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
675 * Fixed minor bug in IDENTIFY command reply sending, which
676 caused various weird problems during JOIN when it was
677 resolving names for users. Affected file silcd/command.c.
679 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
681 * Fixed the IDENTIFY command reply sending to chech better valid
682 clients. It was possible to send incomplete list of replies.
683 Affected file silcd/command.c.
685 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
687 * Added silc_client_command[s]_[un]register functions now to
688 dynamically register the commands in client library. Removed
689 the static table of commands. This allows the client library
690 to call commands without causing the application to know about
691 what commands library has called.
693 Removed the INFO command reply kludge to detect when the command
694 was called by library. Now library use its own command reply
695 function for INFO command.
697 Added function silc_client_command_call to call a command.
698 Application can use it to call command, not access the structure
701 Now all commands that are sent by the client library (not
702 explicitly sent by application) use own command reply functions.
704 Affected files around lib/silcclient/ and in
705 irssi/src/silc/core/.
707 * Fixed the WHOIS command reply sending to chech better valid
708 clients. It was possible to send incomplete list of replies.
710 Fixed the WHOIS and IDENTIFY to send the request to router
711 if normal server did not do it and did not find any results.
713 Affected file silcd/command.c.
715 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
717 * Moved the internal data from SilcClient context into its
718 own file, not accesible to application. Affected files
719 lib/silcclient/client.h and lib/silcclient/client_internal.h,
720 and other files in client library.
722 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
724 * Added doc/examples installation target in Makefile.am.pre.
727 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
729 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
730 commands the found client entry will be removed from the
731 cache, after notifying application about the error. Affected
732 file lib/silcclient/command_reply.c.
734 * Changed the /MSG to check for exact nickname user gave, and
735 not let `nick' match `nick@host' if it is only one found. Now,
736 user must type the exact nickname (like nick@host2) even if
737 there are no more than one same nicks found. This is to avoid
738 a possibility of sending nickname to wrong nickname since
739 `nick' could match `nick@host'. Affected file is
740 irssi/src/core/silc-servers.c.
742 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
744 * Do not print "you are now server operator" or similar when
745 giving /away command. Affected files are
746 irssi/src/silc/core/client_ops.c, silc-servers.h.
748 * Made the silc_server_command_pending_error_check to send
749 the same command reply payload it received back to the
750 original sender of the command. This way all arguments
751 that was received by the server will be received by the
752 client too. Affected file silcd/command.c.
754 * Added the silc_idcache_add to return the created cache entry
755 to a pointer. Affected file lib/silccore/silcidcache.[ch].
757 * Add global clients to expire if they are not on any channel.
758 This is because normal server will never know if they signoff
759 if they are not on any channel. The cache expiry will take
760 case of these entries. This is done by normal servers only.
761 The affected files are silcd/command_reply.c,
762 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
764 * If server receives invalid ID notification for WHOIS or
765 IDENTIFY and the ID exists in the lists, it is removed.
766 Affected file silcd/command_reply.c.
768 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
769 in client then client entry that it matches is searched and
770 the nickname is printed on the screen for user. Affected
771 file irssi/src/silc/core/client_ops.c.
773 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
775 * Use cache entry expire time in the LIST command reply to
776 purge old entries from the cache after the LIST command
777 reply has been received. This way we don't have non-existent
778 entries in the cache for too long. Affected file is
779 silcd/command_reply.c.
781 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
783 * If we are normal server, and we've not resolved client info
784 in WHOIS or IDENTIFY from router, and it is global client,
785 we'll check whether it is on some channel. If it is not
786 then we cannot be sure about its validity and will resolve it
787 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
788 file silcd/command.c.
790 * Search channel by name (if possible) rather than by ID
791 in IDENTIFY command's command reply. Affected file is
792 silcd/command_reply.c.
794 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
796 * Distribute to the channel passphrase in CMODE_CHANGE notify.
797 Updated specs and implemented it. Affected file silcd/command.c,
798 silcd/packet_send.c and silcd/packet_receive.c.
800 * Implemented the <founder auth> payload handling in the JOIN
801 command. If provided all conditions for channel joining
802 except requirement to provide correct passphrase can be
803 overrided by the channel founder. Updated the protocol specs.
804 Affected file silcd/command.c.
806 Added support for founder auth in JOIN command in client
807 library. Fixed the parsing of the JOIN command now to support
808 all options as they should be. The affected file is
809 lib/silcclient/command.c.
811 * Optimized the WHOIS and IDENTIFY commands to send the request
812 to router only if it includes nicknames or other names. If
813 they include only IDs then check the local cache first before
814 routing. Affected file is silcd/command.c.
816 * Added channels topic announcements. Affected file is
817 silcd/packet_receive.c and silcd/server.c.
819 * Fixed the silc_server_send_notify_topic_set to really destine
820 the packet to channel. Affected file silcd/packet_send.c.
822 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
823 library. Affected file lib/silcclient/client_notify.c.
825 * Added UMODE announcements. Affected file silcd/server.c.
827 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
829 * Memory leak fixes in:
831 lib/silcutil/silcsockconn.c
832 lib/silcske/silcske.c
835 lib/silccrypt/silcpkcs.c
836 lib/silccore/silccommand.c
837 lib/silccore/silcidcache.c
842 * ROBOdoc documented the lib/silcske/groups.h file and a
843 bit changed the interface for better.
845 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
847 * Update the client entry context in the ID cache after
848 nick change. Affected file lib/silcclient/command.c.
849 Fixes the CUMODE command when regaining founder privileges,
850 and a little WHOIS problem.
852 * Fixed silc_net_gethostbyname to correctly call the
853 inet_ntop. Affected file lib/silcutil/silcnet.c.
855 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
857 * Added IPv6 support checking to the configure.in.pre, added
858 also --enable-ipv6 option to override the check. Affected
859 file configure.in.pre.
861 * The silc_thread_create now calls the start function
862 directly if threads support is not compiled in. Removes
863 ugly #ifdef's from generic code. Affected files are
864 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
866 * Added silc_net_gethostby[name/addr]_async to asynchronously
867 resolve. Affected files are lib/silcutil/silcnet.[ch].
869 * Added support for rendering IPv6 based server, client and
870 channel IDs. Affected file lib/silcutil/silcutil.c.
872 * Added support for creating IPv6 based server IDs. Affected
873 file is silcd/serverid.c.
875 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
877 * Added silc_net_gethostby[addr/name] into the
878 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
879 routines. Added silc_net_is_ip[4/6]. Affected file is
880 lib/silcutil/unix/silcunixnet.c. All routines that take
881 address as argument now supports both IPv4 and IPv6 addresses.
883 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
885 * Fixed LIST command reply sending in server. Affected file
888 * Server now sends the kicker's client ID in the KICK notify
889 to the kicked client. Affected file silcd/command.c.
891 * The client library now parses the kickers client ID and
892 UI displays it. Affected files lib/silcclient/client_notify.c
893 and irssi/src/silc/core/silc-channels.c, module-formats.c.
895 * Made all payload parsing function prototypes consistent.
896 They all take now const unsigned char * and uint32 pair as
897 the payload data instead of SilcBuffer. Changes all around
898 the source tree. Other unsigned char* -> const unsigned char*
899 changes around the tree as well.
901 * Optimized SFTP client and server packet sending not to
902 allocate new buffer for each packet but to recycle the
903 first allocated buffer. Affected files are
904 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
906 * Optimized the SFTP client to use SilcList instead of
907 SilcDList for requests, because it is faster. Affected file
908 is lib/silcsftp/sftp_client.c.
910 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
911 into lib/silccore/silcid.[ch].
913 Renamed silcpayload.[ch] into silcargument.[ch].
915 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
917 * If client entry is deleted with active key agreement
918 session, abort the session.
920 The silc_client_abort_key_agreement now calls the completion
921 callback with new SILC_KEY_AGREEMENT_ABORTED status.
923 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
926 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
928 * Don't use __restrict in older GCC's. Affected file is
929 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
931 * silc_net_localhost now attempts to reverse lookup the
932 IP/hostname. Affected file lib/silcutil/silcnet.c.
934 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
935 command. It can be used to gain founder privileges at
936 the same time when joining the channel.
938 Defined that the SILC_NOTIFY_TYPE_KICKED send the
939 kicker's client ID as well. Updated protocol specs.
941 Defined that the server must send SILC_COMMAND_IDENTIFY
942 command reply with error status to client who sent
943 private message with invalid client ID.
945 Updated the protocol specification.
947 * Added silc_server_send_command_reply to send any
948 command reply. Affected file silcd/packet_send.[ch].
950 * Added silc_id_payload_encode_data to encode ID payload
951 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
953 * The server now send IDENTIFY command reply with error
954 status if client ID in private message is invalid. Affected
955 file silcd/packet_receive.c.
957 * Save the server key file with server's IP address in
958 the filename instead of hostname. The affected file is
959 irssi/src/silc/core/client_ops.c.
961 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
963 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
966 * Added libtool support for compiling shared objects in
967 lib/silcsim. Affected file configure.in.pre and
968 lib/silcsim/Makefile.am. Original patch by cras.
970 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>

975 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
977 * Fixed silc_client_channel_message to not try to decrypt
978 the message twice if it resolved the destination client
979 information. This could cause of dropping one channel
980 message. Affected file lib/silcclient/client_channel.c.
982 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
984 * Added silc_client_run_one into lib/silcclient/silcapi.h and
985 lib/silcclient/client.c. This function is used when the SILC
986 Client is run under some other scheduler, or event loop or
987 main loop. On GUI applications, for example this may be
988 desired to used to run the client under the GUI application's
989 main loop. Typically the GUI application would register an
990 idle task that calls this function multiple times in a second
991 to quickly process the SILC specific data.
993 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
995 * Fixed silc_server_drop() for dropping the supplementary
996 groups as well, this could cause a security hole on some
999 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1001 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

1012 Affected file irssi/src/silc/core/client_ops.c.
1014 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1016 * Fixed the silc_idcache_list_* routines to really support
1017 the dynamic list. Fixes a crash. Affected file is
1018 lib/silccore/silcidcache.c.
1020 * Fixed the LIST command reply to really call LIST command's
1021 pending callbacks. Affected file silcd/command_reply.c.
1023 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1025 * Update conn->local_entry->nickname after giving NICK
1026 command. Affected file lib/silcclient/command.c.
1028 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1030 * Added the [pid] option to the silcd configuration file
1032 Affected files: serverconfig.[ch] and silcd.c
1034 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1036 * Save fingerprint in WHOIS command reply in server.
1037 Affected file silcd/command_reply.c.
1039 * Fixed NICK commands pending callback registration.
1040 Affected file lib/silcclient/command.c.
1042 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1044 * Use ++server->cmd_ident when sending commands in server,
1045 instead of random number. Affected file silcd/command.c.
1047 * Fixed GETKEY command reply to call actually GETKEY pending
1048 command callbacks. Affected file silcd/command_reply.c.
1050 * A bit stricter check for nicknames. Check for same nickname
1051 in NICK command also. Affected file silcd/command.c.
1053 * Do not call INFO command everytime client ID changes, only
1054 during first connecting. Affected file lib/silcclient/client.c.
1056 * Set the new nickname only after successful command reply for
1057 NICK command is returned by server. Affected file
1058 lib/silcclient/command.c.
1060 * Remove nicknames from nicklist during server_signoff notify.
1061 Should fix /NAMES bit more. The affected file is
1062 irssi/src/silc/core/silc-channels.c.
1064 * Added `fingerprint' field to the SilcIDListData in the
1065 silcd/idlist.h to hold the fingerprint of the client's
1068 Send the fingerprint of the client's public key in WHOIS
1071 Affected files silcd/command.c, and silcd/idlist.[ch].
1073 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1074 create fingerprint from given data.
1076 * Show the fingerprint of the client's public key in WHOIS.
1077 Affected files irssi/src/module-formats.[ch] and
1078 irssi/src/silc/core/client_ops.c.
1080 * Format the multiple same nicknames also during JOIN and
1081 NICK_CHANGE notifys. Affected file is
1082 lib/silcclient/client_notify.c.
1084 * Do not print error on screen for invalid private message
1085 payload since it can come if someone is sending private
1086 messages with wrong key. Affected file
1087 lib/silccore/silcprivate.c.
1089 * Fixed multiple concurrent /PING crash. Affected file
1090 lib/silcclient/command.c.
1092 * Changed the wrong ID encoding. All IP addresses must be
1093 in MSB first order in encoded format. They were encoded
1094 wrong and was in LSB format. Affected files are
1095 silcd/serverid.c, lib/silcutil/silcutil.c.
1097 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1099 * Call the `connect' client operation through the scheduler
1100 in case of error. Affected file lib/silcclient/client.c.
1102 * Call the `failure' client operation even if the error
1103 occurred locally during a protocol. Affected file is
1104 lib/silcclient/protocol.c.
1106 * Added support of sending LIST command to router from normal
1107 server. This way normal server can get list of all channels
1108 in the network too. Fixed the channel list sending in the
1109 server too. Affected files are silcd/command.c, and
1110 silcd/command_reply.[ch].
1112 * Added silc_server_update_channels_by_server and
1113 silc_server_remove_channels_by_server. They are used during
1114 disconnection of primary router and in backup router protocol.
1115 Affected file silcd/server_util.[ch], silcd/server.c and
1116 silcd/server_backup.c.
1118 * Fixed channel adding to global list in IDENTIFY command
1119 reply in server. Affected file silcd/command_reply.c.

1123 * If the incoming packet type is REKEY or REKEY_DONE process
1124 that packet always synchronously. Fixes yet another MAC
1125 failed error on slow (dialup) connections. Affected file
1126 lib/silcclient/client.c and silcd/server.c.
1128 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1130 * Call check_version SKE callback for initiator too. Affected
1131 file lib/silcske/silcske.c.
1133 * Implemented fix for security hole found in the SKE that was
1134 fixed in the specification few days back; the initiator's
1135 public key is now added to the HASH value computation.
1136 Added backwards support for the old way of doing it too, for
1137 old clients and old servers. Affected file is
1138 lib/silcske/silcske.c.
1140 * Enabled mutual authentication by default in SKE. If initiator
1141 is not providing mutual authentication the responder will
1142 force it. This will provide the proof of posession of the
1143 private key for responder. The affected files are
1144 lib/silcclient/protocol.c and silcd/protocol.c.
1146 * Do not cache anymore the server's public key during SKE.
1147 We do mutual authentication so the proof of posession of
1148 private key is done, and if the server is authenticated in
1149 conn auth protocol with public key we must have the public
1150 key already. Affected file silcd/protocol.c.
1152 * Added new global debug variable: silc_debug_hexdump. If
1153 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1154 file lib/silcutil/silclog.[ch].
1156 * Fixed compilation warning due to char * -> const char *.
1157 Affected files lib/silcutil/silcnet.h, and
1158 lib/silccore/silcauth.[ch].
1160 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1162 * Fixed CMODE command when new channel key was created. If
1163 the creation failed the old key was removed. Next time giving
1164 same command would crash the server since the old key was
1165 freed already. Affected file silcd/command.c.
1167 * Fixed the silc_server_announce_get_channels to not crash
1168 on reconnect. Affected file silcd/server.c.
1170 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1172 * Added silc_log_set_debug_string function to set a regex
1173 string to match for debug output. Only the function names,
1174 or filenames matching the given debug string is actually
1175 printed. This way it is possible to filter out those debug
1176 strings that user is not interested in.
1178 Fixed a bug in silc_string_regexify.
1180 Affected files lib/silcutil/silclog.[ch], and
1181 lib/silcutil/unix/silcunixutil.c.
1183 * Changed the -d options in both server and Irssi SILC client
1184 to take the debug string as argument. Affected files
1185 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1187 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1189 * Added silc_hash_babbleprint to create a Bubble Babble
1190 Encoded fingerprint. The encoding is developed by Antti
1191 Huima (draft-huima-babble-01.txt), and it creates human
1192 readable strings out of binary data. Affected file
1193 lib/silccrypt/silchash.[ch].
1195 * Print the babble print now in addition of fingerprint as well
1196 in Irssi SILC client. Affected files are
1197 irssi/src/fe-common/silc/module-formats.[ch],
1198 irssi/src/fe-common/silc/core/client_ops.c.
1200 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1202 * Fixed a security problem found in SKE. The initiator's
1203 public key too is now added to the HASH hash value creation
1204 which is signed by the responder to create the SIGN value.
1205 This will prevent anyone in the middle to lie to the responder
1206 about the initiator's public key. If this is done now, the
1207 man in the middle will get caught. Updated the protocol
1210 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1212 * Better installation directory handling. Configure module
1213 paths and other paths automatically to example_silc* files
1214 in doc/. A patch by toma.
1216 * Fixed compiler warning from MPI library, and from SILC RNG.
1219 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1220 It can be configured with ./configure. A patch by toma.
1222 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1224 * Find correct make to use in prepare-clean. A patch by
1225 toma. Affected file prepare-clean.
1227 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1229 * Added irssi variables use_auto_addr, auto_bind_ip,
1230 auto_bind_port and auto_public_ip.
1232 * Changed the interface for silc_client_send_key_agreement
1233 in lib/silcclient/silcapi.h
1237 irssi/src/silc/core/silc-core.c
1239 lib/silcclient/silcapi.h
1240 irssi/src/silc/core/silc-channels.c
1241 lib/silcclient/client_keyagr.c
1244 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1246 * Added silc_pkcs_public_key_compare to compare two
1247 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1249 * Check that the client who set the founder mode on the
1250 channel is the same client that is giving the founder
1251 mode to itself. It is done by comparing the saved public
1252 key (it is saved even in the authentication is passphrase).
1253 Affected file silcd/command.c.
1255 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1257 * Do not process packet for disconnected socket connection.
1258 Affected file lib/silccore/silcpacket.c.
1260 * Process the DISCONNECT packet through scheduler in the
1261 client library. Affected file lib/silcclient/client.c.
1263 * Fixed the silc_client_packet_parse to not to increase
1264 the packet sequence number if the conn->sock and the
1265 current socket connection is not same. This can happen
1266 for example during key agreement when the conn includes
1267 multiple socket connections (listeners). Affected file
1268 lib/silcclient/client.c.
1270 * The sender of the file transfer request now provides also
1271 the pointer (listener) for the key exchange protocol. If
1272 the listener cannot be created then it sends empty key
1273 agreement and lets the receiver provide the listener.
1275 Added `local_ip' and `local_port' arguments to the
1276 silc_client_file_send. If they are provided they are used,
1277 if not then it will attempt to find local IP address, if
1278 not found or bind fails then the remote client will provide
1281 Affected files are lib/silcclient/client_ftp.c and
1282 lib/silcclient/silcapi.h.
1284 * Extended the FILE SEND command to support defining the
1285 local IP and port for key exchange listener. They are
1286 optional. Affected file irssi/src/silc/core/silc-servers.c.
1288 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1290 * Defined to WHOIS command reply the sending of fingerprint
1291 of the client's public key (if the proof of posession of the
1292 corresponding private key is verified by the server).
1293 Updated to the protocol specification.
1295 * Added support of receiving the client's public key's
1296 fingerprint in command reply in client library. Affected
1297 file is lib/silcclient/command_reply.c, and
1298 lib/silcclient/idlist.[ch].
1300 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1302 * Do not send over 128 chars long nickname to the server
1303 in NICK command. Affected file lib/silcclient/command.c.
1305 * Do not send over 256 chars long channel names to the server
1306 in JOIN command. Affected file lib/silcclient/command.c.
1308 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1310 * Assure that silc_server_close_connection cannot be called
1311 twice for same socket context. Affected file is
1314 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1316 * Send error message to application if opening file for
1317 writing during file transfer fails. Affected file is
1318 lib/silcclient/client_ftp.c.
1320 Remove all file transfer sessions for a client that we're
1321 removing from ID cache.
1323 Affected file is lib/silcclient/client_ftp.c.
1325 * Fixed silc_net_addr2bin to return correct address. Affected
1326 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1328 * Fixed file transfer session removing on signoff notify.
1329 Affected file irssi/src/silc/core/silc-servers.c.
1331 * Added the SilcClientFileError to be returned in the monitor
1332 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1333 Affected file lib/silcclient/silcapi.h.
1335 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1337 * Fixed a crash in silc_client_ftp_free_sessions and
1338 silc_client_ftp_session_free_client. Affected file
1339 lib/silcclient/client_ftp.c.
1341 * Added `disabled' field in the SilcChannelEntry in the server
1342 to indicate if the server entry is disabled. Affected file
1343 silcd/idlist.h, silcd/command[_reply].c.
1345 * SILC server adds now /var/run/silcd.pid everytime it is
1346 started. Affected file silcd/silcd.c.
1348 * Added silc_server_packet_send_clients to send a packet to
1349 the provided table of client entries. Affected file
1350 silcd/packet_send.[ch].
1352 * Fixed a crash in client resolving in client_prvmsg.c in
1353 client library. Affected file lib/silcclient/client_prvmsg.c.
1355 * Do not actually remove the client directly from ID cache
1356 during SERVER_SIGNOFF, but invalidate it. This way we
1357 preserve the WHOWAS info for the client. Affected file
1358 silcd/server_util.c.
1360 * Fixed SERVER_SIGNOFF notify handling in the server. The
1361 server is now able to process incoming SERVER_SIGNOFF notify
1362 for a server that it doesn't even know about. It will remove
1363 the clients provided in the notify. Affected file
1364 silcd/packet_receive.c.
1366 * Check for partial packet in data queue after every packet that
1367 was found from the queue. Return and wait for more data if
1368 there is partial data in queue. Affected file is
1369 lib/silccore/silcpacket.c.
1371 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1373 * Added SilcClietFileError enum to indicate error in
1374 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1375 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1376 Affected files lib/silcclient/silcapi.h and
1377 lib/silcclient/client_ftp.c.
1379 * Check that newsize in silc_buffer_realloc is larger than
1380 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1382 * Added better monitor of file transfers. It now monitors
1383 key agreement protocol during the file transfer too. Added
1384 error reporting too. Affected files
1385 irssi/src/silc/core/silc-servers.c,
1386 irssi/src/fe-common/silc/module-formats.[ch].
1388 * Wrote a help file for FILE command.
1390 * Added silc_rng_global_get_byte_fast to get not-so-secure
1391 random data as fast as possible. Random data is read from
1392 /dev/urandom if available and from the SILC RNG if not
1393 available. It is used in padding generation. Affected file
1394 lib/silccrypt/silcrng.[ch].
1396 * All packets in client library are now processed synchronously.
1397 Optimized packet processing a lot. Affected file
1398 lib/silcclient/client.c.
1400 * All server connection packets are processing synchronously
1401 now in server, to optimize packet processing. Affected file
1404 * Include files are installed now only in Toolkit distribution
1405 if make install is given. Affected files: all Makefile.am's.
1407 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1409 * Assure that silc_client_notify_by_server_resolve does not
1410 resolve the client information multiple times. If it cannot
1411 be found by the first it cannot be found at all. Affected
1412 file lib/silcclient/client_notify.c.
1414 * Fixed WHOWAS command reply calling. Affected file
1415 lib/silcclient/command_reply.c.
1417 * Removed all references to silc_idlist_get_client from the
1418 Irssi SILC client since that call is internal call used by
1419 the library. The Irssi SILC client will use now client
1420 retrieval functions found in silcapi.h.
1422 * Fixed a bug in resolving nickname info before sending
1423 private message. It used freed memory. Affected file
1424 irssi/src/silc/core/silc-servers.c.
1426 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1428 * Assure my_channels statistics cannot go negative in server.
1429 Affected files silcd/server.c, silcd/server_util.c.
1431 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1433 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1435 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1437 * Win32 Toolkit changes. Affected files

1445 * Added silc_net_localip to return local host's IP address.
1446 Affected file lib/silcutil/silcnet.[ch].
1448 * If key exchange or rekey protocol is active for a connection
1449 parse all packets syncronously since there might be packets
1450 in packet queue that we are not able to process without first
1451 processing packets before them. Affected file silcd/server,
1452 lib/silcclient/client.c.
1454 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1455 whether library should continue processing the packet.
1456 Affected file lib/silccore/silcpacket.h.
1458 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1459 SilcSFTPMonitorData to SFTP server to monitor various
1460 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1461 lib/silcsftp/sftp_server.c.
1463 * Added silc_file_size to return file size. Affected file
1464 lib/silcutil/silcutil.[ch].
1466 * Implemented the file transfer support for the client library.
1467 Added preliminary support for simple client to client one-file
1468 transmission. Affected file lib/silcclient/client_ftp.c,
1469 lib/silccilent/client.[ch].
1471 * Added new local command FILE to the Irssi SILC Client.
1472 It is used to perform the file transfer. It has subcommands
1473 SEND, RECEIVE, SHOW and CLOSE. Affected files
1474 irssi/src/silc/core/client_ops.c,
1475 irssi/src/silc/core/silc-server.[ch].
1477 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1479 * Relay the SILC_PACKET_FTP in the server. Affected files
1480 silcd/server.c and silcd/packet_receive.c.

1484 * Renamed silc_file_read and silc_file_write to functions
1485 silc_file_readfile and silc_file_writefile. Added function
1486 silc_file_open and silc_file_close. Affected files
1487 lib/silcutil/silcutil.[ch].
1489 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1491 * Resolve the client info when received private message or
1492 channel message for a client which nickname we don't know.
1493 Affected files lib/silcclient/client_prvmsg.c and
1494 lib/silcclient/client_channel.c.
1496 * Do not crash in /KEY if client is not connected. Affected
1497 file irssi/src/silc/core/silc-channels.c.
1499 * Added SilcClientStatus field to the SilcClientEntry in the
1500 lib/silcclient/idlist.h.
1502 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1503 is incomplete and is being resolved, it won't be resolved
1506 Make sure also that USERS command reply does not resolve
1507 twice information. Affected file is
1508 lib/silcclient/command_reply.c.
1510 Make sure that silc_client_get_clients_by_list does not
1511 resolve twice same information.
1513 * Check for valid client->id in the silc_server_free_client_data.
1514 Affected file silcd/server.c.
1516 * Fixed /GETKEY nick@server not to crash if the server entry
1517 is not found. Affected file lib/silcclient/command.c.
1519 * Fixed the silc_server_check_cmode_rights to check the
1520 requested modes correctly. Affected file silcd/command.c.
1522 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1524 * Better checks for non-printable chars in nick added.
1525 Affected file silcd/command.c.
1527 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1529 * Call the silc_server_udpate_servers_by_server in the
1530 primary router that comes back online in the backup resuming
1531 protocol. Otherwise it routes packets wrong. Affected file
1532 silcd/server_util.[ch], silcd/server_backup.c.
1534 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1536 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1537 lib/silcutil/silcbuffmt.[ch].
1539 * Redefined the SILC packet header to include the padding
1540 length. Affected file lib/silccore/silcpacket.[ch].
1542 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1543 length for maximum padding up to 128 bytes). Affected
1544 file lib/silccore/silcpacket.h.
1546 * Removed all backwards support for old 0.5.x MAC thingies.
1547 The SILC packet header change makes it impossible to be
1548 backwards compatible.
1550 * Send the ENDING packet with timeout in the backup resuming
1551 protocol. This is to assure that all routers has connected
1552 to the primary router. Affected file silcd/server_backup.c.
1554 * Changed the RNG to take the first IV from random data. It
1555 used to take it from zero actually. Changed the RNG also
1556 to use /dev/urandom during session. /dev/random is used
1557 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1559 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1561 * Changed the SILC packet header to have the first two bytes
1562 (the packet length) encrypted. Affected files aroung the
1563 code tree, lib/silccore/silcpacket.[ch]. Removed the
1564 SilcPacketCheckDecrypt callback. It is not needed anymore
1565 since the silc_packet_receive_process will determine now
1566 whether the packet is normal or special.
1568 * Implemented the unidirectional MAC keys. Affected files
1569 lib/silcske/silcske.c, silcd/protocol.c and
1570 lib/silcclient/protocol.c.
1572 * Implemented the packet sequence number to the MAC computation.
1573 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1574 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1575 lib/silcclient/protocol.c.
1577 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1579 * Allow backup router to announce servers. All servers
1580 announced by backup router are added to the global list
1581 automatically. Update hte server's socket to our primary
1582 router also when backup router announces a server.
1583 Affected file silcd/packet_receive.c.
1585 * Do not update the client->router in the function
1586 silc_server_udpate_clients_by_server if the client is on
1587 global list. We might fail to find any specific server
1588 for locally connected clients and local cell clients. They
1589 should still use the `from' and not `to' as client->router.
1590 This fixes backup router resuming protocol. Affected file
1591 silcd/server_util.c.
1593 * Decrease channel statistics count only if the channel
1594 deletion worked. Affected files are silcd/server.c and
1595 silcd/server_util.c.
1597 * Added silc_server_update_servers_by_server to update origin
1598 of all server entries. Used during backup router protocol.
1599 Affected files silcd/server_util.[ch], silcd/server.c. and
1600 silcd/backup_router.c.
1602 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1603 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1604 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1605 lib/silccrypt/silchmac.c.
1607 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1609 * Assure that router cannot reroute the same channel message
1610 to the sender. Affected file silcd/packet_receive.c.
1612 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1614 * Made better checks that the channel message is not sent
1615 to the router it came from. Affected file is
1616 silcd/packet_send.c. Fixed memory leak too.
1618 * Announce informations for incoming router connection, but
1619 only after checking if it is replaced by backup router.
1620 Affected file silcd/packet_receive.c.
1622 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1624 * Fixed the backup resuming protocol to work in multiple
1625 router environment. Affected file silcd/server_backup.c.
1627 * Route packet only to one router in the function
1628 silc_server_packet_send_to_channel. Affected file is
1629 silcd/packet_send.c.
1631 * Fixed silc_server_send_notify_dest to set the broadcast
1632 flag. Fixed the silc_server_send_notify_topic to actually
1633 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1634 Affected file silcd/packet_send.c.
1636 * Changed the SFTP Filesystem interface. Changed the
1637 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1638 the filesystem operation function. The SilcSFTPFilesystem
1639 is now a context that is allocated by all filesystem allocation
1640 functions and it already includes the operations structure
1641 and filesystem specific context. It is given as argument
1642 now to the silc_sftp_server_start. This made the interface
1643 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1644 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1646 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1648 * Changed the backup router adding and getting interfaces
1649 in the server. The router that will be replaced by the
1650 specified backup router is now sent as argument. Affected
1651 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1654 * Added silc_net_addr2bin_ne to return the binary form of
1655 the IP address in network byte order. Affected files
1656 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1658 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1660 * Check for existing server ID in silc_server_new_server
1661 and in silc_server_connect_to_router_final and remove the
1662 old entry if it exists. Affected file silcd/packet_receive.c,
1665 * Send the channel message always to only one router, either
1666 in upstream or downstream. Affected file is
1667 silcd/packet_send.c.
1669 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1671 * Wrote the definition of the backup resuming protocol to the
1672 protocol specification.
1674 * Removed one redundant channel key generation from normal
1675 server during joining procedure. Removed one redundant
1676 channel key sending from server to router during joining
1677 procedure. Affected file silcd/command.c.
1679 * Made minor bugfixes to the backup router resuming protocol.
1680 Affected file silcd/server_backup.c, server.c.
1682 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1684 * Added --disable-asm configuration option. Affected files
1685 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1688 * Implemented the backup resuming protocol that is used to
1689 resume the primary router position in the cell after the
1690 primary router comes back online. Affected files
1691 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1692 and silcd/server_util.[ch].
1694 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1696 * Sleep two (2) seconds after sending QUIT command to server.
1697 Affected file lib/silcclient/command.c.
1699 * Assure that if outgoing data buffer is pending do not force
1700 send any data. Affected file silcd/packet_send.c.
1702 * Assure that if outgoing data buffer is pending do not force
1703 send any data. Affected file lib/silcclient/client.c.
1705 * Implemented the backup router support when the primary router
1706 goes down. The servers and routers can now use the backup
1707 router as new primary router without loosing connectivity.
1709 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1711 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1712 in the server to indicate disabled entry. All data read
1713 from the connection will be ignored and no data is sent
1714 for entry that is disabled. Affected files are
1715 silcd/idlist.h, silcd/server.c.
1717 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1719 * Created SFTP client and server test programs in the
1720 lib/silcsftp/tests directory.
1722 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1724 * Implemented memory filesystem (virtual filesystem) for
1725 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1728 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1730 * Implemented the SFTP (SSH File Transfer Protocol) to the
1731 lib/silcsftp. It includes SFTP client and SFTP server
1734 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1736 * Moved lib/silccore/silcprotocol.[ch] to the
1737 lib/silcutil library.
1739 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1740 take variable argument list pointer as argument. Affected
1741 file lib/silcutil/silcbuffmt.[ch].
1743 * Added silc_buffer_set function that is used to set data
1744 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1745 Affected file lib/silcutil/silcbuffer.h.
1747 * Changed various routines in the core library to use the new
1748 silc_buffer_set instead of allocating new buffer only for
1751 * Added 64-bit value formatting and unformatting support to the
1752 silc_buffer_[un]format routines. Affected file is
1753 lib/silcutil/silcbuffmt.[ch].
1755 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1756 to includes/bitmove.h.
1758 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1760 * Fixed channel user mode saving in client library. Affected
1761 file lib/silcclient/command[_reply].c.
1763 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1765 * Defined the file transfer to the SILC Protocol. Added
1766 new packet type SILC_PACKET_FTP and defined File Transfer
1767 Payload. The mandatory file transfer protocol is SFTP
1768 (SSH File Transfer Protocol). Affected file in addition
1769 of the internet draft is lib/silccore/silcpacket.h.
1771 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1772 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1773 is used as part of backup router protocol when the primary
1774 router of the cell is back online and wishes to resume
1775 the position as primary router.
1777 * Redefined the MAC generation keys in the protocol. The
1778 same key is not used anymore in both direction. Both
1779 direction will now use different keys for sending and
1780 receiving. This fixes a potential security flaw. This
1781 change causes incompatibilities in the protocol.
1783 * Redefined also the MAC computation from the packet.
1784 An packet sequence number is now added to the MAC
1785 computation. This prevents possible replay attacks against
1786 the protocol. This change too causes incompatibilities
1789 Added `sequence' field to the SilcPacketContext to hold
1790 the current sequence number for the packet.
1792 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1794 * Added `created' field to the SilcIDListData in the file
1795 silcd/idlist.h to indicate the time when the entry was
1798 * Added `created' field to the SilcChannelEntry too. Affected
1799 file silcd/idlist.h.
1801 * Added `creation_time' aguments to all the announcement functions
1802 in the server. If it is provided then only the entries that
1803 was created after the provided time frame are actually
1804 announced. Affected file silcd/server.[ch].
1806 * The protocol says that the Channel ID's IP address must be
1807 based on the router's IP address. Added check for this in
1808 the silc_server_new_channel when processing incoming New Channel
1809 Payload. Affected file silcd/packet_receive.c.
1811 * Print out the correct version with --version in SILC client.
1812 Affected file irssi/src/silc/core/silc-core.c.
1814 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1816 * Fixed WHOWAS command to check for completnes of the client
1817 entry always, not just when the command is coming from client.
1818 Affected file silcd/command.c.
1820 * Added new function silc_server_packet_queue_purge to purge the
1821 outgoing data queue to the network. After the function returns
1822 it is guaranteed that the outgoing packet queue is empty.
1823 Affected file silcd/packet_send.[ch].
1825 * Purge the outgoing packet queue in the rekey protocol's final
1826 callback to assure that all rekey packets go to the network
1827 before quitting the protocol. Affected file silcd/server.c.
1829 * Added silc_client_packet_queue_parse as similar function as
1830 in server to the client library. The affected file is
1831 lib/silcclient/client.c.
1833 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1835 * Splitted silcd/server.c and created silcd/server_util.[ch]
1836 for utility functions.
1838 * Added new socket flag SILC_SF_DISABLED to indicate that the
1839 connection is open but nothing can be sent to or received from
1840 the connection. Affected file lib/silcutil/silsockconn.[ch].
1841 The checking for disabled socket is checked in the low level
1842 silc_socket_write and silc_socket_read functions.
1844 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1846 * Allow only nicknames and channel names that fits into the
1847 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1849 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1851 * When processing JOIN command reply in server check that if
1852 the channel exists in our global list we'll move it the local
1853 list. Affected file silcd/command_reply.c.
1855 * Fixed the check whether client is joined on the channel already
1856 in JOIN command. Affected file lib/silcclient/command.c.
1858 * Fixed the JOIN command reply to check whether the channel
1859 already exists. Affected file lib/silcclient/command_reply.c.
1861 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1863 * Added silc_ske_status_string to map the SKE error numbers
1864 to readable strings. The affected files are
1865 lib/silcske/silcske[_status].[ch].
1867 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1869 * Do not show the private channels on the WHOIS channel list
1870 as it is not allowed by the protocol. The affected file is
1873 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1875 * Assure that the packet length digged from the actual packet
1876 is something sensible in the silc_packet_decrypt_rest_special
1877 in lib/silccrypt/silcpacket.c.
1879 * Free and NULL the allocated pointer in silc_hmac_alloc if
1880 the HMAC allocation fails. The affected file is
1881 lib/silccrypt/silchmac.c.
1883 * Print the selected security properties to the log files in
1884 the server. Affected file silcd/protocol.c.
1886 * Add SKE's reference counter even if calling the completion
1887 callback manually. Otherwise it goes negative, although it
1888 does not cause any problems. The affected file is
1889 lib/silcske/silcske.c.
1891 * Remove the client entry with short timeout after giving the
1892 KILL command. Affected file lib/silcclient/command.c.
1894 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1895 case all found clients are already disconnected (WHOWAS would
1896 found them) in the server. Affected file silcd/command.c.
1898 * Update the last_receive (time of last data received) to be
1899 updated only when received private or channel message so that
1900 the idle time showed in WHOIS makes more sense.
1902 * Added boolean field `valid' in to the SilcClientEntry in the
1903 client library to indicate whether the entry is valid or not.
1904 This fixes the nickname change bug on channel when changing
1905 the nickname to be same than the old (like nick to Nick) the
1906 nickname formatter doesn't set the new nick anymore to Nick@host.
1907 Affected file lib/silcclient/idlist.[ch].
1909 * Now actually fixed the nickname changing on disconnection.
1910 Added new function silc_change_nick to the Irssi SILC Client.
1911 Affected file irssi/src/silc/core/client_ops.c,
1912 irssi/src/silc/core/silc-nicklist.[ch].
1914 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1916 * Check that the public key exists in the GETKEY command before
1917 trying to encode it. Affected file silcd/command.c.
1919 * Print some notifications on received public keys with GETKEY
1920 command in the Irssi SILC Client. Affected files are
1921 irssi/src/fe-common/silc/module-formats.[ch],
1922 irssi/src/silc/core/client_ops.c.
1924 * Use IDENTIFY command to resolve the server information in the
1925 GETKEY command instead of INFO command. Affected file
1926 lib/silcclient/command.c.
1928 * All command reply functions in the client library now calls
1929 the pending command reply callbacks even if an error has
1930 occurred. The server has done this a long time and now it was
1931 time to move the client library to this as well. Now all
1932 errors can be delivered back to the pending command reply
1933 callbacks if necessary. Affected files are
1934 lib/silcclient/command[_reply].[ch].
1936 * Change the nickname on disconnection back to the username
1937 because in reconnect the server will enforce it to it anyway.
1938 Affected file irssi/src/silc/core/silc-servers.c.
1940 * Fixed a config file parsing bug in the Irssi SILC client.
1941 Affected file irssi/src/silc/core/clientconfig.c.
1943 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1945 * When printing the channel mode on JOIN, verify that the
1946 channel key and channel's HMAC are valid. Affected file
1947 irssi/src/silc/core/client_ops.c.
1949 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1951 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1952 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1953 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1955 * Removed channel key rekey task deleting from the function
1956 silc_server_save_channel_key. Affected file silcd/server.c.
1957 Added explicit timeout task context instead that is used to
1958 delete the task if we are registering a new task before the
1959 new task has elapsed.
1961 * When channel key rekey occurs the client library now saves
1962 the old channel key for a short period of time (10 seconds) and
1963 is able to use it in case some is still sending channel
1964 messages encrypted with the old key after the rekey. Affected
1965 file lib/silcclient/[idlist.h|client_channel.c].
1967 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1969 * Added check to the silc_server_new_id_real to not accept
1970 new ID if it is the sender's own ID. Affected file is
1971 silcd/packet_receive.c.
1973 * Assure that we do not announce ourself or the one we've
1974 sending our announcements when we're router and are announcing
1975 servers to our primary router. Affected file silcd/server.c.
1977 * Fixed silc_server_command_identify_check_client to assemble
1978 correct WHOIS packet. It send corrupted WHOIS packet and
1979 caused problem with router to router connections. Affected
1980 file silcd/command.c.
1982 Fixed also silc_server_command_whois_check the same way
1983 as for the IDENTIFY command.
1985 * Added new SilcIDListStatus to the server in the SilcIDListData
1986 structure. The status now includes the current status of
1987 the entry (like registered, resolved etc.). Affected file
1988 silcd/idlist.[ch]. Defined a bunch of different status types
1989 as well. This replaced the old boolean registered field as well.
1991 Added resolve_cmd_ident field to the SilcClientEntry structure
1992 too so that if the entry is for example being resolved so
1993 another command may attach to the same pending command reply
1994 without requiring to resolve the same entry again. This concept
1995 should optimize the WHOIS and the IDENTIFY resolving under
1996 heavy load by taking away unnecessary resolving for entries
1997 that are being resolved already.
1999 Added support for adding multiple pending commands for one
2000 command idenfier. Affected file silcd/command[_reply].[ch].
2002 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2003 before deleting the data. Otherwise the hash table will have
2004 freed data in comparison functions. Affected file is
2005 silcd/command_reply.c.
2007 * Fixed silc_idlist_replace_client_id to add the new entry to
2008 the cache with NULL nickname. Otherwise there will be invalid
2009 memory as the nickname after the nickname is freed. Affected
2010 file silcd/packet_receive.c.
2012 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2013 saved into wrong slots because the previous number of entries
2014 was not taken into account. Affected file silcd/idlist.c.
2015 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2017 * If we are router and we receive JOIN notify to a channel that
2018 does not have any users then notified client is marked as the
2019 channel founder, as it is it. The affected file is
2020 silcd/packet_receive.c
2022 * Added to the extended hash table API's table_del_*ext functions
2023 the destructor as argument too, so that the caller can decide
2024 which destructor to use or whether to use destructor at all.
2025 Affected file lib/silcutil/silchashtable.[ch].
2027 * Fixed ID Cache purging. It actually deleted the entries from
2028 the hash table after the data was freed. The hash table ended
2029 up comparing freed memory. The affected file is
2030 lib/silccore/silcidcache.c.
2032 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2034 * Fixed Irssi SILC client's KILL command's HELP syntax.
2036 * The USERS command now resolves the detailed user information
2037 if the userinfo field is missing. Affected file is
2038 lib/silcclient/command_reply.c.
2040 * Do not print error in silc_file_read if the read file does
2041 not exist. Just silently return NULL. Affected file is
2042 lib/silcutil/silcutil.c.
2044 * Fixed the silc_log_output to not wine about NULL filename
2045 and to not create some bogus " " filename. Affected file is
2046 lib/silcutil/silclog.c.
2048 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2050 * Fixed various printing bugs on the user interface in the
2051 Irssi SILC Client. Minor changes that were forgotten from
2054 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2056 * Fixed the configure.in.pre and the compilation and distribution
2057 environment to support the new autoconf 2.52. That version is
2058 now required to compile the CVS trunk.
2060 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2062 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2063 to generally parse user@fqdn format strings. Affected file
2064 lib/silcutil/silcutil.c.
2066 * Added nickname_format and nickname_force_format fields to the
2067 SilcClientParams structure. The first one defines the format
2068 for the nicknames that the library will enforce if the receives
2069 multiple same nicknames. The second one is boolean value and
2070 can be used to force the library to always enforce the format
2071 to the nicknames regardles whether there are multiple nicknames
2072 or not. This configurable formatting was employed to flexibly
2073 support accessing multiple nicknames from the user interface.
2074 The userinterface can now set the nicknames to what ever format
2075 they prefer. Affected file lib/silcclient/silcapi.h.
2077 Added function silc_client_nickname_format to the file
2078 lib/silcclient/idlist.c. It performs the nickname formatting.
2080 Added new field `hostname´ to the SilcClientEntry context.
2081 It holds the hostname of the client. Affected file is
2082 lib/silcclient/idlist.h.
2084 * Irssi SILC Client sets the nicknames in nick@hostn format.
2085 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2086 irssi/src/silc/core/silc-core.c.
2088 The WHOIS printing now also shows both the real nickname and
2089 the formatted nickname so that user knows how to access the
2090 user if there are multiple same nicknames cached. Affected
2091 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2092 printing formatting too to take the hostname now as a separate
2093 argument. The Affected file is
2094 irssi/src/fe-common/silc/modules-formats.[ch].
2096 * Changed the silc_client_get_clients_local to accept the formatted
2097 nickname as argument. It accepts the real nickname too but the
2098 formatted nickname can be used to find the true entry from
2099 multiple entries. Affected file lib/silcclient/silcapi.h and
2100 lib/silcclient/idlist.c.
2102 * Added nickname_format_parse field to the SilcClientParams.
2103 It is a callback function provided by the application to parse
2104 the nickname out of the formatted nickname string. The library
2105 calls it to get the nickname from the formatted string. Since
2106 the application generally knows better the format of the nickname
2107 string it parses it instead of the library, even though library
2108 encodes the formatted string. If the callback function is not
2109 provided then the library will use the string as is. The
2110 affected file is lib/silcclient/silcapi.h.
2112 * All the nickname strings passed to the client library in
2113 commands are now expected to be formatted nickname strings.
2114 If the command does not support the formatted nickname string
2115 it will assume that the sent string is the actual nickname.
2116 Affected file lib/silcclient/command.c.
2118 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2120 * Added public key authentication support to OPER and SILCOPER
2121 commands in the client library. Affected file is
2122 lib/silcclient/command.c.
2124 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2126 * Changed the get_auth_methdod client operation to be asynchronous.
2127 It can be async if the application resolves the authentication
2128 method from the server during the negotiation. Added new
2129 SilcGetAuthMeth completion callback that the application will
2130 call after resolving the authentication method.
2132 Added function silc_client_request_authentication_method that
2133 the application can use to resolve the authentication method
2134 from the server. Added also SilcConnectionAuthRequest callback
2135 that the library will call after the server has replied. The
2136 application can call this function if it does not know the
2137 current authentication method.
2139 Affected files are lib/silcclient/client.c and
2140 lib/silcclient/silcapi.h.
2142 * The Irssi SILC client now automatically resolves the authentication
2143 method incase any configuration information is not present (and
2144 currently there never is). The affected file is
2145 irssi/src/silc/core/client_ops.c.
2147 * Fixed public key authentication from the client library.
2148 Affected file lib/silcclient/protocol.c. Changed also the
2149 protocol specification about the public key authentication in
2150 the connection authentication protocol. The actual data to be
2151 signed is now computed with a hash function before signing.
2153 * Fixed the public key authentication from the server as well.
2154 Affected file silcd/protocol.c.
2156 * Removed the mlock()'s from the memory allocation routines.
2157 Affected file lib/silcutil/silcmemory.c. The ./configure does
2158 not check anymore for the mlock(). Affected file is
2161 * Fixed USERS command in server to allow the execution of the
2162 command for private and secret channels if the client sending
2163 the command is on the channel. Affected file silcd/command.c.
2165 * Fixed silc_client_get_clients_local to return the clients
2166 count correctly. It could return wrong value. Affected file
2167 lib/silcclient/idlist.c.
2169 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2171 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2172 types. The assembler optimizations seemed not to like 64-bit
2173 data types. The assmebler optimizations thus are now enabled
2174 also for BSD systems as opposed to only enable them for Linux.
2176 * Do not check for threads at all on BSD systems. Affected
2177 file configure.in.pre.
2179 * Removed -n and -h options from the Irssi SILC Client since
2180 they are not used in silc.
2182 * Fixed the prime generation to assure that the first digit
2183 of the generated random number is not zero since our conversion
2184 routines does not like number strings that starts with zero
2185 digit. If zero digit is seen the random number is regenerated.
2186 This caused some corrupted RSA keys when the zero first digit
2187 was met. Affected file lib/silcmath/silcprimegen.c.
2189 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2191 * Fixed WIN32 configuration in the ./configure script.
2192 Fixed to include xti.h on environments that has it.
2193 Patches by Carsten Ilchmann and andrew.
2195 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2197 * Changed the silc_id_create_client_id to be collision
2198 resistant. It is now assured that there cannot be created
2199 two same client ID's. I suspect that some weird bugs in
2200 the server were actually caused by duplicate Client IDs.
2201 Affected file silcd/serverid.[ch]. A router receiving
2202 new ID now also assures and informs the sending server
2203 if the ID caused collision.
2205 * Changed the silc_id_create_channel_id to also assure that
2206 there are no collisions.
2208 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2210 * Statement about ignoring the Mutual Authentication flag when
2211 performing rekey with PFS was a bit misleading. It is ignored
2212 if it was set in the initial negotiation, it cannot be even
2213 set in the rekey. Fixed in the ke-auth draft. Started the
2214 new versions of the protocol drafts in the doc/.
2216 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2218 * Fixed a bug in silc_client_command_identify_save when saving
2219 new channel information. The channel name was no duplicated
2220 and caused crash on exit. Affected file is
2221 lib/silcclient/command_reply.c.
2223 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2225 * Fixed the getkey command handling in the server. Send just
2226 empty OK reply to the sender if the key could not be fetched
2227 (but everything else was ok, like the key just was not available).
2228 Changed the public key parameter to optional in the protocol
2229 specs so that empty OK reply can be sent. Affected file
2232 Added a message to Irssi SILC client to tell to user if the
2233 server did not return a public key.
2235 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2237 * Fixed a channel key regeneration bug. It registered new
2238 timeout tasks exponentially until all system resources were
2239 used. Affected file silcd/server.c.
2241 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2243 * Added the SILC Document generator to the scripts/silcdoc.
2244 It can be used to generate the Toolkit Reference Manual out
2245 of the source tree. Internally it will also use the RoboDoc
2246 generator now imported in util/robodoc.
2248 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2250 * Added couple of return's in rekey protocol if error orccurred
2251 during the protocol. The execution must be terminated.
2252 Affected file silcd/protocol.c. Also, terminate the protocol
2253 always with timeout.
2255 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2257 * The client's Client ID was created initally from the wrong
2258 nickname (it could have been in format nick@host) in the
2259 silc_server_new_client. Affected file silcd/packet_receive.c
2261 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2263 * Added some SILC_LOG_ERROR's to various error conditions
2264 if client could not be added to ID cache. Affected files
2265 silcd/packet_receive.c and silcd/server.c.
2267 * When client's sock->user_data is freed, NULL also the
2268 client->router and client->connection pointers. Added check
2269 for these pointers being NULL to various places around the
2270 code. Affected file silcd/server.c.
2272 * Added client->data.registered == TRUE checks to various
2273 places around the code to assure that unregistered client's
2274 are not handled when it is not allowed. Affected file
2277 * Added `bool registered' fields to all
2278 silc_idlist_[server|client]_get_* routines to indicate whether
2279 the fetched client needs to be registered or not. Affected
2280 file silcd/idlist.[ch].
2282 * Add your own entry as registered to the ID cache in the
2283 server. Affected file server.c.
2285 * Fixed a bug in silc_server_new_server. The SilcServer was
2286 set as the new server's context instead of SilcServerEntry.
2287 This naturally caused some weird bugs.
2289 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2291 * Do not delete the channel rekey task when adding it
2292 for in silc_server_create_channel_key.
2294 * Changed the silc_server_create_channel_key to return
2295 TRUE or FALSE to indicate the success of the channel key
2298 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2300 * Fixed MSVC++ project files and added missing files to
2301 Makefiles under win32/.
2303 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2305 * Do not add TCP_NODELAY flag if the operating system
2306 does not have it defined. Affected files are
2307 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2309 * Fixed buffer overflow from Irssi SILC Client. Affected
2310 file irssi/src/fe-common/core/themes.c.
2312 * Fixed double free in client library in the file
2313 lib/silcclient/client.c when disconnecting from server.
2315 * Applied double free patch from cras to Irssi SILC client.
2316 Affected files irssi/src/core/[modules/expandos].c
2318 * Fixed the disconnection handling to Irssi SILC Client.
2319 The application must call silc_client_close_connection
2320 in ops->connect client operation in case of failure of
2321 the connection. Affected file is
2322 irssi/src/silc/core/client_ops.c.
2324 * Do not set sock->protocol to NULL in the function
2325 silc_client_close_connection after executing the protocol's
2326 final callback since the sock might not be valid anymore.
2327 Affected file lib/silcclient/client.c.
2329 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2331 * Do not enable SILC_THREADS if the linking with libpthread
2332 did not happen. Affected file configure.in.pre.
2334 * Added notion to protocol specification that server must
2335 verify the sent authentication payload with CMODE when
2336 setting the channel founder key. Implemented it to the
2337 server. Affected file silcd/command.c.
2339 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2341 * Added _EXTRA_DIST SILC distribution variable to the
2342 distributions file. It is used to conditionally add extra
2343 files or directories to the specific distribution. Affected
2344 files ./prepare, Makefile.am.pre and distributions.
2346 Removed the `_' from the start of the distribution names.
2349 * Added README.WIN32 for instructions to compile the Toolkit
2352 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2354 * Fixed a double free in disconnection in the server. Affected
2355 file is silcd/server.c.
2357 * Fixed the lib/silcske/groups.c to work now also with GMP
2358 MP library. The string conversion did not work when using
2359 specific base and the base is indicated in the string as well.
2361 * Created win32/ directory which now includes MSVC++ specific
2362 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2363 It will appear only in the toolkit distribution
2365 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2367 * Changed the key material distribution function in case when
2368 the hash output is too short. The data is now concatenated
2369 a bit differently than it used to. Made the change to the
2370 SKE protocol specification.
2372 * Added better GMP detection to configure.in.pre. A patch
2375 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2377 * Fixed a minor bug in SKE that might cause some problem on
2378 some platforms. Affected file lib/silcske/silcske.c.
2380 * Added the cookie checking for initiator in the SKE. It checks
2381 that the responder returns the sent cookie unmodified. The
2382 affected file is lib/silcske/silcske.c. Added new SKE
2383 error type INVALID_COOKIE that can be sent during the
2384 negotiation. Fixed some memory leaks as well.
2386 * Added the "invalid cookie" error message to Irssi SILC client's
2389 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2391 * Added `task_max' field to the SilcClientParams to indicate
2392 the maximum tasks the scheduler can handle. If set to zero,
2393 default values are used. Affected file lib/silcclient/silcapi.h.
2395 * Fixed memory leaks in silc_client_close_connection. Affected
2396 file lib/silcclient/client.c.
2398 * Added silc_client_del_client_entry to client library to free
2399 all memory of given client entry. Affected file is
2400 lib/silcclient/idlist.[ch].
2402 * Added new functions silc_client_del_channel and
2403 silc_client_del_server to delete channel and server entries.
2404 Affected file lib/silcclient/[silcapi.h/idlist.c].
2406 * Removed silc_client_del_client_by_id from silcapi.h.
2408 * Fixed the INFO command to return the server's own info
2409 correctly when querying by Server ID. Affected file is
2412 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2414 * Removed the non-blocking settings in WIN32 code in the
2415 silc_sock_[read/write] and added SleepEx instead. Affected
2416 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2417 of input data is now checked with FIONREAD and ioctlsocket.
2419 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2421 * Call silc_schedule_task_del_by_context in the
2422 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2423 Affected file lib/silccore/silcprotocol.c.
2425 * Call silc_protocol_cancel for active protocols in the
2426 silc_server_close_connection if the funtion
2427 silc_server_free_sock_user_data has not been called.
2428 Affected file silcd/server.c.
2430 * Generic tasks cannot be deleted using the del_by_fd
2431 task deleting function since generic tasks does not match
2432 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2434 * Added a notion to SILCOPER help file that the SILCOPER works
2435 only on router server, not on normal server.
2437 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2439 * Added for WIN32 support for the new scheduler as well.
2440 Affected file lib/silcutil/win32/silcwin32schedule.c.
2442 * Fixed the SHA1 implementation to work on various platforms.
2444 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2446 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2447 API. It is part of the scheduler now. Everything else is
2448 as previously but some functions has changed their names.
2449 Checkout the lib/silcutil/silcschedule.h for the interface.
2450 Updated all applications to use the new interface. Affected
2451 files are lib/silcutil/silcschedule.[ch].
2453 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * Found a bug in the SKE implementation. The HASH value,
2456 specified by the protocol, was not computed correctly. The
2457 public key of the responder was not added to the computation
2458 even though it is mandatory. Affected file lib/silcske/silcske.c.
2459 This unfortunately causes incompatibilities with older
2460 clients and servers.
2462 * Added WIN32 specific network init and uninit functions:
2463 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2464 the Winsock2. Affected file lib/silcutil/silcnet.h and
2465 lib/silcutil/win32/silcwin32net.c.
2467 * Set the socket always to nonblocking mode on WIN32 after
2468 reading data or writing data. Affected file is
2469 lib/silcutil/win32/silcwin32sockconn.c.
2471 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2473 * Fixed various compilation problems under WIN32. Affected
2474 files lib/silcutil/win32/silcwin32thread.c and
2475 lib/silcutil/win32/silcwin32schedule.c.
2477 * Removed all _internal.h #includes from public header
2478 files. Internal headers must never be included from
2481 Removed also the lib/silcske/payload_internal.h file.
2483 * All include files that may be needed (public and some others
2484 included by the public headers) by application developers are
2485 now copied to the ./includes directory. It does not copy any
2486 internal headers. Affected file Makefile.defines.pre and all
2487 Makefile.am's under lib/ and subdirs.
2489 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2491 * Do not change the ~/.silc directory's permissions automatically.
2492 Affected file irssi/src/silc/core/clientutil.c.
2494 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2496 * Do not cancel the protocol in silc_server_close_connection
2497 it might cause recursion. Now cancelled in the function
2498 silc_server_free_sock_user_data. Affected file silcd/server.c.
2500 * Fixed the silc_server_remove_clients_by_server to regenerate
2501 the channel keys correctly finally. Added also new function
2502 silc_server_remove_clients_channels to actually do it.
2503 Affected file silcd/server.c.
2505 * Fixed the silc_server_new_channel to not crash by giving
2506 wrong router to the new channel. Affected file is
2507 silcd/packet_receive.c.
2509 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2511 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2512 which is given as argument to the silc_client_alloc now.
2513 It can be used to configure the client and set various parameters
2514 that affect the function of the client.
2516 * The USERS command in server did not check whether the channel
2517 is private or secret. Affected file silcd/command.c.
2519 * Added new argument to the USERS command in protocol specification.
2520 The USERS command now can take the channel name as argument
2521 as well. Added support for this in client and server and
2522 updated the protocol specs.
2524 * Completed the GETKEY command in client. It can be now used
2525 to fetch also servers public key not only some clients.
2526 Affected files lib/silcclient/command[_reply].c.
2528 * Added silc_client_get_server to return server entry by the
2529 server name. Affected files lib/silcclient/silcapi.h and
2532 * Redefined the IDENTIFY command in protocol specification to be
2533 more generic. It now can be used to query information about
2534 any entity in the SILC Network, including clients, servers and
2535 channels. The query may be based either the entity's name
2536 or the ID. Added support for this in both client and server.
2538 Affected files silcd/command.c and lib/silcclient/command.c
2539 and command_reply.c.
2541 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2542 the _from_client and _from_server functions. Affected file
2545 * Added silc_client_get_channel_by_id_resolve to the file
2546 lib/silcclient/silcapi.h to resolve channel information by
2547 its ID. Added also silc_client_get_channel_by_id that
2548 does not resolve it from the server.
2550 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2552 * Added SilcServerEntry context into the client library
2553 to represent one server. The INFO command now allocates
2554 these to save the resolved server info. For now on the
2555 client library will also keep information about servers,
2556 connected and resolved with INFO.
2558 The INFO command now allocates the SilcServerEntry context
2559 and saves the server info there. The COMMAND_REPLY in
2560 the INFO now returns the parameters to application in
2561 same order as defined in the protocol specification.
2563 The entries are cached in the client->server_cache.
2565 * The INFO command is now issued after received the Client ID
2566 from the server. Affected file lib/silcclient/client.c.
2568 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2569 to the application as the mode changer might be server.
2570 It is guaranteed that NULL is not returned anymore to the
2571 application. Affected file lib/silcclient/client_notify.c.
2573 The ID Type is now also passed to the application so that
2574 it can check whether the returned entry is SilcClientEntry
2577 Added new function silc_client_get_server_by_id to return
2578 the server entry by ID. Affected files are the
2579 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2581 * Do not create the channel in the Irssi SILC Client when issuing
2582 the JOIN command but when received the sucessful JOIN command
2583 reply. Otherwise the channel might get created even though we
2584 could not join it. The Affected file is
2585 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2587 * Fixed a channel joining bug in router. The router must also
2588 check the channel modes, invite and ban lists etc. when serving
2589 the JOIN command sent by normal server. Affected file is
2590 silcd/command.c. The router now resolves the client's
2591 information from the server who sent the JOIN command if it
2592 does not know it, and processes the JOIN command only after
2595 * Changed the SilcCommandCb to take new argument; void *context2.
2596 Affected file lib/silccore/silccommand.h
2598 The second argument in the command callbacks in the server now
2599 includes the SilcServerCommandReplyContext if the command was
2600 called as pending command callback from the command reply.
2601 Otherwise it is NULL. When called as pending the status of the
2602 command reply will be checked and if it was erronous the
2603 error will be sent to the original sender of the command.
2604 This way the client always receives the error messages even
2605 though the server was actually the one who received the error
2606 when it resent the command to router, for example. Affected
2607 files silcd/command[_reply].[ch].
2609 * Fixed sending WHOWAS command's error message to client if
2610 the requested client could not be found. It was missing.
2613 * Changed the CMODE and CUMODE commands reply arguments in the
2614 protocol specification. The Channel ID is now sent in both
2615 of the commands to identify the channel. Implemented this
2616 new feature to the client and server. Affected files
2617 lib/silcclient/command_reply.c and silcd/command.c.
2619 * Made better checks for invite and ban lists in the JOIN
2620 command in server. Affected file silcd/command.c.
2622 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2624 * The server now performs the incoming host IP/DNS lookup
2625 using the silc_socket_host_lookup and thus does not block
2626 the server anymore. Affected file silcd/server.c.
2628 * Completed the multi-thread support for SILC Scheduler in
2629 the lib/silcutil/silcschedule.c.
2631 * Fixed the configure.in.pre to detect the pthread correctly
2634 * Fixed a deadlock in silc_task_queue_wakeup in the file
2635 lib/silcutil/silctask.c.
2637 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2639 * Added new function silc_schedule_wakeup that is used in
2640 multi-threaded environment to wakeup the main thread's
2641 schduler. It needs to be used when a thread adds a new task
2642 or removes a task from task queues. After waking up, the
2643 scheduler will detect the task queue changes. If threads
2644 support is not compiled in this function has no effect.
2645 Implemented the wakeup mechanism to both Unix and WIN32
2646 systems. Affected files are lib/silcutil/silcschedule.[ch],
2647 lib/silcutil/unix/silcunixschedule.c and the
2648 lib/silcutil/win32/silcwin32schedule.c.
2650 * Added new function silc_task_queue_wakeup to wakeup the
2651 scheduler by the specified task queue. Affected file
2652 lib/silcutil/silctask.[ch].
2654 * The silc_socket_host_lookup_start now wakes up the scheduler
2655 after adding the timeout task. Affected file is
2656 lib/silcutil/silcsockconn.c.
2658 * The silc_socket_host_lookup is synchronous now if the threads
2659 support is not compiled in. However, the callback is still
2660 called asyncronously through the scheduler, anyway. Affected
2661 file lib/silcutil/silcsockconn.c.
2663 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2665 * Added new function silc_socket_host_lookup to perform
2666 asynchronous IP and FQDN lookups for the socket connection.
2667 Affected files lib/silcutil/silcsockconn.[ch].
2669 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2671 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2672 that may or may not compile the mutex support in.
2674 Changed the silc_mutex_alloc interface. It allocates the
2675 mutex now to the sent pointer and returns TRUE or FALSE.
2677 Affected file lib/silcutil/silcmutex.h.
2679 * Wrote the SILC Task Queue interface to support multi-threads.
2680 Affected file lib/silcutil/silctask.[ch].
2682 * Wrote the SILC Scheduler to support multi-threads. Affected
2683 file lib/silcutil/silcschedule.c.
2685 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2687 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2688 in lib/silcutil/win32/.
2690 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2692 * Defined SILC Mutex API and SILC Thread API and implemented
2693 them for Unix. Affected files are
2694 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2695 lib/silcutil/unix/silcunixmutex.c and
2696 lib/silcutil/unix/silcunixthread.c.
2698 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2700 * Fixed the silc_server_remove_clients_by_server's channel
2701 key re-generation. The hash table handling was incorrect
2702 and would not work with many channels. Affected file is
2705 * Fixed some memory leaks around the server code.
2707 * Rewrote the silc_server_get_users_on_channel to support IPv6
2708 based Client ID's. Affected file silcd/server.c.
2710 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2711 specification. However, a separate document must be written
2712 to define the detailed signing procedure and the payload
2713 associated with the flag. Defined the flag to the
2714 lib/silccore/silcchannel.h as well.
2716 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2718 * Changed the dynamic tables to static size tables in the
2719 lib/silccrypt/silchmac.c.
2721 * Removed GCC dependencies from the code. A patch by cras.
2723 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2725 * Do not show the error "Error receiving packet bla bla"
2726 in server if it really was not an error (-2 means that reading
2727 is pending). Affected file silcd/server.c.
2729 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2731 * Fixed a possible crash in silc_server_remove_clients_by_server
2732 in silcd/server.c. Fixed there also some memory leaks.
2734 * Fixed the silc_idlist_replace_client_id. It could replace
2735 wrong key in the hash table. Affected file silcd/idlist.c.
2737 * Do not check whether there are global users on the channel
2738 if the channel->global_users is FALSE. Affected functions
2739 silc_server_remove_from_one_channel and
2740 silc_server_remove_from_channels in silcd/server.c. Also,
2741 do not check if the removed client is local as we can be
2742 sure that global client was not removed from the channel
2743 and checking for global users is not needed.
2745 * The silc_server_remove_clients_by_server now re-generates
2746 the channel keys correctly for those channels that had
2747 clients removed from them. Affected file silcd/server.c.
2749 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2751 * Found the reason of random crashes in the server. We weren't
2752 ignoring the SIGPIPE signal (which can be sent in write())
2753 and it crashed the server. Affected file silcd/silcd.c.
2755 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2757 * Assure that sock->user_data is not NULL in the function
2758 silc_server_packet_send in silcd/packet_send.c.
2760 * Disconnect the remote connection if it could not be added
2761 to any ID lists in the server. The affected file is
2764 * Check in silc_server_packet_send[_real/dest] that the
2765 socket is not disconnecting and ignore the data if it is.
2766 Affected file silcd/packet_send.c.
2768 * Define inline to __inline on native WIN32 compilation.
2769 Affected file includes/silcwin32.h.
2771 * Added some explicit type casts for inline code since MSVC
2772 require them. Affected files lib/silcutil/silcbuffer.h,
2773 lib/trq/silcdlist.h and lib/trq/silclist.h.
2775 * Print warning in log files from now on if the packet
2776 decryption fails. Affected file silcd/server.c.
2778 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2780 * Changed the `say' client operation's interface to accept
2781 new `type' argument to indicate the type of the message sent
2782 by the library. The application may filter the library's
2783 messages according the type. The affected file is the
2784 lib/silcclient/silcapi.h.
2786 * Added two new functions to lib/silcclient/silcapi.h:
2787 silc_client_del_client and silc_client_del_client_by_id.
2788 Affected file lib/silcclient/idlist.c.
2790 * Moved the clientincludes.h from includes/ to silc/ and
2791 serverincludes.h from includes/ to silcd/.
2793 * The modes for the CMODE and CUMODE are now passed as
2794 uint32 for application with COMMAND_REPLY. The affected
2795 file is lib/silcclient/command_reply.c.
2797 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2799 * /WHOIS without arguments shows client's own information.
2800 Affected file lib/silcclient/command.c.
2802 * Changed PING to not accept any arguments. The specs
2803 says that client can ping only the connected server so
2804 requiring an argument is not needed. Affected file is
2805 lib/silcclient/command.c.
2807 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2809 * Fixed a fatal bug in private message sending and reception
2810 encryption and decryption when using private message keys.
2811 The implementation was incorrect and did not follow the
2812 specification. It causd that some of the message were
2813 lost since it did not use the sending and receiving keys
2814 as the protocol suggests. This has been fixed and will cause
2815 incompatibilities with older clients when sending private
2816 message encrypted with private message keys. Affected files
2817 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2818 and various other in Irssi SILC Client.
2820 Added `responder' boolean argument to the functions
2821 silc_client_add_private_message_key[_ske] to indicate when
2822 the key is added as responder or initiator of the key
2825 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2827 * Removed the silc_ske_check_version function and created
2828 a SilcSKECheckVersion callback. Added also a function
2829 silc_ske_set_callbacks that is now used to set all SKE
2830 callbacks. The callback functions are not given to
2831 the SKE functions anymore, but this function is used to
2834 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2836 * Added `silc_version' argument to the silc_client_alloc
2837 to define the version of the application for the library.
2838 The library will use the version string to compare it
2839 against the remote host's (usually a server) version
2840 string. Affected file lib/silcclient/silcapi.h
2842 * Added the KE protocol context to Key Agreement context
2843 in client library so that we can abort the SKE if it
2844 is in process when we get timeout. Affected file is
2845 lib/silcclient/client_keyagr.c.
2847 * Do not resolve the client ID forever if it returns in the
2848 first time that such client does not exist. This was done
2849 for example with private message. Affected file is
2850 lib/silcclient/client_prvmsg.c.
2852 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2854 * Do not add regex.h for WIN32. The affected file
2855 includes/silcincludes.h.
2857 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2858 not work yet 100%. It generates the DLL's automatically
2859 when compiling with --with-win32 under cygwin.
2861 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2863 * lib/contrib/regex.c is not compiled on WIN32.
2865 * Added silc_net_get_socket_opt function to the
2866 lib/silcutil/silcnet.h.
2868 * Added includes/silcwin32.h for WIN32 specific includes
2871 * Do not use ptime structure or any of the posix process
2872 functions on WIN32 in lib/silccrypt/silrng.c.
2874 * Added silc_gettimeofday to provide generic function
2875 for struct timeval on all platforms. Added the function
2876 to lib/silcutil/silcutil.h.
2878 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2880 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2881 library as they clearly belong there. As a plus side we
2882 can make the actual socket connection routines platform
2885 Added also new generic function silc_socket_read and
2886 silc_socket_write (that used to be silc_packet_[read/write].
2887 The implementation of these are platform specific.
2889 * Added WIN32 specific routines of silc_socket_[read/write]
2890 to lib/silcutil/win32/silcwin32sockconn.c.
2892 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2894 * Added preliminary support for native WIN32 compilation under
2895 cygwin (using the -mno-cygwin option for GCC) to the
2896 ./configure.in.pre. The --with-win32 now prepares the
2897 compilation for native WIN32.
2899 * Rewrote the SILC Scheduler interface in the file
2900 lib/silcutil/silcschedule.h. The scheduler is now context
2901 based and does not have anymore any global static scheduler.
2902 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2903 and created lib/silcutil/win32 directory for WIN32 based
2906 * Added Unix specific network routines to the
2907 lib/silcutil/unix/silcunixnet.c and the old
2908 lib/silcutil/silcnet.c includes now only generic routines.
2910 Added WIN32 specific network routines to the
2911 lib/silcutil/win32/silcwin32net.c.
2913 * Added Unix specific utility functions from the
2914 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2916 * Added WIN32 SILC Scheduler to the file
2917 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2920 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2922 * Do not handle JOIN notify in the server if the target client
2923 is not registered (idata->registered == FALSE). The affected
2924 file is silcd/packet_receive.c.
2926 * Update the nickrec->founder in event_cumode in the Irssi SILC
2927 client. Affected file irssi/src/silc/core/silc-channels.c.
2929 * Fixed the CUMODE_CHANGE notify handling in the server when
2930 server and router are announcing their clients on channels.
2931 Now the mode changes are saved and notified correctly. The
2932 affected file is /silcd/packet_receive.c.
2934 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2935 They really did not replace the cache entry in the ID Cache.
2936 Now they do that. Affected file silcd/idlist.c.
2938 * Fixed the KICK notify handling in the Irssi SILC client to
2939 update the channel records so that the kicked client does not
2940 appear to be on the channel. The affected file is
2941 irssi/src/silc/core/silc-channels.c.
2943 * Always update the conn->current_channel when executing command
2944 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2946 * Fixed the KILL notify handling in Irssi SILC client to remove
2947 the killed client on all channels.
2949 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2951 * Fixed the silc_parse_command_line to remove extra spaces
2952 from the start and end of the arguments. Affected file is
2953 lib/silcutil/silcutil.c.
2955 * Cancel and free any active protocol in the function
2956 silc_server_close_connection. Affected file silcd/server.c.
2958 * Cancel and free any active protocol in the function
2959 silc_client_close_connction. Affected file is
2960 lib/silcclient/client.c.
2962 * Do not execute the KILL command for clients that are in
2963 history (ie. they are not in the network). Affected file is
2966 * Fixed KILL notify handling, client does not crash anymore.
2967 Affected file irssi/src/silc/core/silc-channels.c.
2969 * Reduced the default packet buffer size from 2048 to 1024 in
2970 lib/silccore/silcpacket.c.
2972 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2973 counter to the SKE context that is incresed when the SKE library
2974 performs async operation outside the library. If the outside
2975 process frees the SKE context and FREED status will be set
2976 and the library will detect after the sync operation that the
2977 libary is freed. The affected files are
2978 lib/silcske/silcske[_status].[ch].
2980 * Resolve the client entry information in the function
2981 silc_client_channel_message to assure that NULL pointer is not
2982 passed as client entry to the application. */
2984 * Fixed the task timeout calculation to assure that there is
2985 never negative timeouts. The affected file is
2986 lib/silcutil/silcschedule.c.
2988 * Fixed the channel user mode notification sending in server.
2989 It was sent point-to-point to the router (or to server by router)
2990 but it needs to be destined to a channel. The routines now
2991 supports sending the channel user mode notifys to the channels
2992 when announcing clients and channels. Affected files are
2993 silcd/server.c and silcd/packet_receive.c.
2995 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2996 It did not actually replace the old channel entry in the cache.
2997 Affected file lib/silcclient/client_notify.c.
2999 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3001 * Fixed a possible crash in silc_packet_send_prepare. It now
3002 assures always that there is enough space in the buffer and
3003 at the tail area of the buffer (for MAC).
3005 Fixed the inbound buffer reallocation in silc_packet_read.
3006 It was old code and did not handle the reallocation correctly.
3009 The affected file is lib/silccore/silcpacket.c.
3011 * Fixed buffer overflow in silc_parse_nickname in the file
3012 lib/silcutil/silcutil.c.
3014 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3016 * make install generates new server keys only if there is not
3019 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3021 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3022 Added check that if the NOREPLY is set then we will not send
3023 the away message. This avoids infinite loop of away messages
3024 if both clients are away. The affected file is
3025 lib/silcclient/client_prvmsg.c.
3027 * Fixed client crash if /NICK was given without arguments.
3028 Affected file lib/silcclient/command.c.
3030 * Server does not send the invite list in INVITE command back
3031 to the client if the list was not altered. Added this notion
3032 to the protocol spec as well. Affected file silcd/command.c.
3034 Fixed possible crash in INVITE command by checking the
3035 value of silc_server_get_client_route command.
3037 * Fixed the INVITE notify type handling. The arguments are now
3038 taken in correct order and client does not crash. The affected
3039 file is irssi/src/silc/core/silc-channels.c.
3041 Removed the "Inviting xxx to channel" message from the
3042 client library away and let the application handle it.
3043 Affected file lib/silcclient/command.c. Added that message
3044 to Irssi SILC client's message formats.
3046 * Fixed CMODE command crash in client. It now checks the
3047 amount of arguments correctly and does not crash. The affected
3048 file is lib/silcclient/command.c.
3050 * Do not create new channel automatically in silc_channels_join
3051 but check whether the channel by that name already exists.
3052 Affected file irssi/silc/core/silc-channels.c.
3054 * Do not send the SERVER_SIGNOFF to router if the disconnected
3055 entity was the router. Affected file silcd/server.c.
3057 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3058 SILC client as it was missing from there.
3060 Added the handling of the KICK notify to the Irssi SILC client
3061 as it was missing. Added "you have been kicked" message to
3062 Irssi SILC client's message modules formats.
3064 Added the handing of the KILL notify to the Irssi SILC client
3065 as it was missing. Added the kill message module formats
3068 The affected file is irssi/src/silc/core/silc-channels.c.
3070 * The router did not save the channel mode the server announced.
3071 Affected file silcd/packet_receive.c.
3073 * Fixed a possible crash in INFO command in server. If the
3074 server did not provide the server info it crashed. Affected
3075 file silcd/command.c.
3077 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3079 * Fixed the GETKEY command in the server to check also the
3080 global list. Otherwise the GETKEY would not work correctly
3081 in normal SILC server. Affected file silcd/command.c.
3083 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3085 * Fixed GETKEY crash, it crashed if the command did not succseed.
3087 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3089 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3090 is now real and not just an macro interface to GMP.
3092 Removed the entire GMP from the source tree and imported new
3093 NSS MPI library instead. Reason for removing GMP is that it is
3094 extremely large and compiles extremely slow. The NSS MPI
3095 is only a few files and compiles in less than 10 seconds.
3096 The speed is also about the same as GMP. The MPI is imported
3097 to lib/silcmath/mpi.
3099 If the system has GMP installed we will still use the GMP.
3100 If it is not then the NSS MPI will be compiled.
3102 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3104 * Merged a long nickname (127 characters long) crash bugfix from
3105 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3107 * Merged a freed memory reference bugfix from Irssi CVS tree.
3108 Affected file irssi/src/core/commands.c.
3110 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3112 * Added the server's public key sving and verification to the
3113 server when performing the SKE. This was missing and the
3114 remote server's (or router's) public key was accepted without
3115 checking whether we have it previously or trust it at all.
3116 Affected file silcd/protocol.c.
3118 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Check in the silc_server_timeout_remote if protocol is active
3121 and make sure that the protocol's final callback is called so
3122 that all memory if freed. Affected file silcd/server.c.
3124 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3126 * silc_server_whois_send_reply crashed the server if the nickname
3127 was 127 characters long. Affected file silcd/command.c.
3129 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3131 * Added sanity check to the silc_server_new_client. If the hostname
3132 is provided inside username then check that the provided hostname
3133 really is the same as the resolved one. If the hostname was not
3134 resolved then check it from the public key. Affected file is
3135 silcd/packet_receive.c.
3137 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3138 if the server disconnected us and the connection is not valid
3139 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3141 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3142 the library to the lib/silcutil/silcutil.[ch].
3144 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3146 * Close log file after open. Affected file
3147 lib/silcutil/silclog.c.
3149 * Check whether sock == NULL in silc_client_send_packet and return
3150 if it is. Affected file lib/silcclient/silcclient.c.
3152 * Check rec->entry == NULL in the Irssi SILC Client before
3153 sending the channel message. Affecte file is
3154 irssi/src/silc/core/silc-servers.c.
3156 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3158 * Merged a splitted window bugfix from Irssi CVS tree. The
3159 affected file is irssi/src/fe-text/textbuffer-view.c.
3161 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3162 It did not print nickname.
3164 * Improved the distributions system a bit.
3166 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3168 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3169 irssi/src/fe-text/gui-window.c.
3171 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3172 to in-active server. The affected file is
3173 irssi/src/silc/core/client_ops.c.
3175 * Resolve the client in USERS command reply if the entry does
3176 not have username resolved. The affected file is
3177 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3178 command to WHOIS command to really resolve stuff. The USERS
3179 is not used any more in any critical section so WHOIS can
3180 be used even though it might be slower than IDENTIFY.
3182 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3185 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3187 * Changed the protocol API a bit more consistent in the
3188 lib/silccore/silcprotocol.[ch].
3190 * Changed the following headers to ROBODoc format:
3192 lib/silccore/silcpayload.h
3193 lib/silccore/silcprotocol.h
3194 lib/silccore/silcsockconn.h
3196 All core library headers are now formatted.
3198 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3200 * Fixed a bug in Irssi SILC client; do not show that you are
3201 server/router operator if you really are not. Affected file is
3202 irssi/src/silc/core/client_ops.c.
3204 * Renamed silc_command_free_payload to silc_command_payload_free.
3205 Affected file lib/silccore/silccommand.h
3207 * Added silcmath.h to include the prototoypes of various routines
3208 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3211 * Changed the following headers to ROBODoc format:
3213 lib/silccore/silcchannel.h
3214 lib/silccore/silccommand.h
3215 lib/silccore/silcid.h
3216 lib/silccore/silcidcache.h
3217 lib/silccore/silcmode.h
3218 lib/silccore/silcnotify.h
3219 lib/silccore/silcpacket.h
3220 lib/silcmath/silcmath.h
3222 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3224 * Added checking to the server code not to start the server if
3225 ciphers and stuff are not configured properly. Affected files
3226 silcd/serverconfig.[h] and silcd/server.c.
3228 * Changed the layout of the header files of the public interfaces
3229 in the SILC libraries. The new layout supports ROBODoc
3230 documentation tool (and some others) so that it is easy to create
3231 a library reference manual. All the other headers and source
3232 code must still follow the CodingStyle document. Also source
3233 code must not include these ROBODoc stuffs, only the headers.
3234 Furthermore, all public interface headers must now be named
3235 by using `silc' prefix, example: silcapi.h, silccipher.h.
3236 Some files were renamed due to this. All the other headers
3237 must not be used as public interfaces. I will update the
3238 CodingStyle document later. Changed following headers, so far:
3240 lib/silcclient/silcapi.h
3241 lib/silccore/silcauth.h
3242 lib/silccore/silcprivate.h
3243 lib/silccrypt/silcdh.h
3245 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3249 * Removed silc_client_packet_send_flush from the client library
3250 as it is not needed. Affected file lib/silcclient/client.[ch].
3252 * Added printing of message of unresolved authentication method
3253 to the Irssi SILC client. Added it to the module formats.
3254 Removed the same message from the client library.
3256 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3258 * Added new distribution feature, DISTLABEL. Every distribution
3259 can define own preprocessor label that can be used in the
3260 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3261 file distributions, acconfig.h.pre and prepare.
3263 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3265 * Added Makefile.defines_int to include the actual definitions
3266 for Makefile.defines.in. Tested the new distribution system,
3267 created distributions and tested installation.
3269 * Added AWAY message printing to the Irssi SILC client. Added
3270 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3272 * Added SCONNECT command to call the SILC's CONNECT command.
3273 Cannot use CONNECT directly since Irssi uses that internally.
3274 Affected file irssi/src/silc/core/silc-servers.c.
3276 Added ACTION local command. It is same as ME command but takes
3277 the channel as mandatory argument.
3279 Rewrote some of the Irssi's help files to suite for SILC
3282 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3284 * Added Makefile.defines[.in] that should for now on be included
3285 in all Makefile.am file in the source tree. That file includes
3286 all common compilation definitions for SILC source tree.
3288 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3290 * Minor changes to the ./prepare script to change the package
3291 name according the distribution name to the configure.in.
3293 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3295 * Created new distribution system. Added file `distributions'
3296 that defines all the distributions that can be created out of
3297 the SILC source tree. The ./prepare script now reads that
3298 file to determine how to prepare the distributions. The
3299 first argument to the ./prepare is the name of the distribution
3300 and second is the version of the distribution. If given
3301 without arguments it creates the default (toolkit) distribution
3302 with the default version (defined in ./prepare).
3304 All Makefile.am files that are subject to the distributions
3305 are now named as Makefile.am.pre. These are ./Makefile.am
3306 and lib/Makefile.am. Others may be changed later.
3308 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3310 * Added invite list, ban list, some key management and connection
3311 error message printing to module formats in the Irssi SILC client.
3313 * Added new silc_client_set_away_message to set the away message
3314 that is back to the person who sent private message. The
3315 affected file lib/silcclient/silcapi.h and the
3316 lib/silcclient/client_prvmsg.c.
3318 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3320 * Fixed the private message sending in the Irssi SILC client,
3321 added local command KEY to the Irssi SILC client.
3323 Added key management and key agreement message formats to the
3324 irssi/src/fe-common/silc/module-formats.[ch].
3326 Added USERS (alias WHO) printing, server/router operator
3327 indication and LIST command printing to the module formats.
3329 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3331 * Fixed channel joining notify handling, cumode notify handling
3332 from Irssi SILC client.
3334 * Added SILC specific module-formats to the Irssi SILC client so
3335 that SILC specific message hilighting, colors etc is possible.
3336 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3338 Added channel mode, channel user mode, actions, notices,
3339 whois and whowas printing to the the module-formats.c.
3341 * Fixed a bug in channel deletion in the server. The channel
3342 is not left to the cache even if the channel founder auth mode
3343 is set when there are no users anymore on the channel. Affected
3344 file silcd/server.c.
3346 * The silc_net_localhost now resolves the entire hostname including
3347 the domain name. Affected file lib/silcutil/silcnet.c.
3349 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3351 * Changed the ask_passphrase client operation to be ascynchronous.
3352 It has now a completion callback and a context that the
3353 application must call after it has got the passphrase from
3354 the user. Affected files lib/silcclient/silcapi.h,
3355 lib/silcclient/protocol.c, lib/silcclient/command.c and
3358 Added SilcAskPassphrase callback that the application calls
3359 to deliver the passphrase to the library.
3361 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3362 The public key verification and especially a certificate
3363 verification is asynchronous procedure.
3365 Added new SILC_SKE_STATUS_PENDING status to indicate the
3366 request is pending and a callback will be called to finalize
3369 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3370 indicate that remote end did not send its public key (or
3371 certificate), even though we require it. Added check for this
3372 condition in the SKE. This was a security bug, now fixed.
3374 Defined new SilcSKEVerifyCbCompletion callback that is called
3375 when the verification process is completed.
3377 The affected files lib/silcske/silcske_status.h and
3378 lib/silcske/silcske.[ch].
3380 * Changed the verify_public_key client operation to be async
3381 as well. Defined SilcVerifyPublicKey callback that is used to
3382 indicate the success of the public key verification process.
3384 Changed the server and client to use the new async client
3387 * Changed the Irssi SILC client's internal scheduler to be called
3388 twice as many times as it used to be. As a result the client
3389 should be a bit faster now. Affected file is
3390 irssi/src/silc/core/silc-core.c.
3392 * Added support to Irssi SILC client of asynchronous public key
3393 verification and passphrase inquiry. Affected file is
3394 irssi/src/silc/core/silc-core.c.
3396 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3398 * Do not say "You have left channel %s" in client library.
3399 Moved it to the application. Affected files are
3400 lib/silcclient/command.c and silc/client_ops.c.
3402 * Fixed silc_client_get_clients. Command context was not
3403 duplicated and was freed memory in the callback. Affected
3404 file lib/silcclient/idlist.c.
3406 * Do not say "you are now talking..." on JOIN command in the
3407 client library. The appliation must handle it.
3409 * Do not say ".. changed topic to" in command reply in the
3410 client libary. The application must handle it.
3412 * Fixed TOPIC command sending in the client library.
3414 * Fixed a memory leak in silc_client_command_free in the file
3415 lib/silcclient/command.c.
3417 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3419 * Imported a modified version of Irssi client to the source tree.
3420 The Irssi will be used to create a new client called
3421 Irssi SILC. Imported to irssi/.
3423 Added silc_core_init_finish function to the Irssi. Affected
3424 file irssi/configure.in.
3426 A lot changes in the Makefile.ams around the irssi tree.
3428 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * Do not rehash if the new size is same as the old size of the
3431 hash table, in the silc_hash_table_rehash*. The affected file
3432 lib/silcutil/silchashtable.c.
3434 * Replaced hash_table_del_by_context calls from the server
3435 (when channel->user_list and client->channels) to the
3436 hash_table_del as it is sufficient and faster.
3438 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3440 * Added silc_hash_table_list, silc_hash_table_get and the
3441 SilcHashTableList structure to provide an alternative way to
3442 traverse the hash table. The affected files are
3443 lib/silcutil/silchashtable.[ch].
3445 * Changed the server's idlist routines to use the hash table
3446 routines to optimize the code.
3448 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3450 * Replaced the client entry's `channel' list and channel entry's
3451 `user_list' list to hash tables for optimized lookup. Changed
3452 the code to use the hash table interface around the code.
3453 Affected file lib/silcd/idlist.[ch].
3455 * Added `auto_rehash' boolean argument to the function
3456 silc_hash_table_alloc to indicate whether the hash table should
3457 auto-rehash when it thinks is appropriate time. It will
3458 increase the hash table size if the there is twice as much
3459 entries in the table than the size of the table, and will
3460 decrease the size if there are twice as less entries than
3461 the size of the table.
3463 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3465 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3467 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3469 * silc_idcache_purge_by_context deletes the entry now by context
3470 as it is supposed to do. Affected file lib/silccore/idcache.c.
3472 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3473 client is not anymore valid (WHOWAS givens the info) and not
3474 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3476 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3478 * Removed the `data' and `data_len' arguments from the ID Cache
3479 interfaces and added `name' argument. ID Cache does not handle
3480 anymore the binary data only a names associated with given ID.
3482 * When hashing a Client ID with silc_hash_id the entire ID is
3483 not hashed anymore, instead only the hash of the Client ID is
3484 hashed. This way we can access the Client ID from the cache
3485 with Client ID but with the hash of the ID (which is a hash of
3486 the nickname) as well without any difference in performance.
3488 Added also silc_idcache_find_by_id_one_ext to do one on one
3489 searching when we have the actual ID. Added also function
3490 silc_hash_client_id_compare. The affected files are
3491 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3493 * When hashing the name associated with a ID it is always done
3494 in lowercase. This way we can access the cache without worrying
3495 about case-sensitivity, even though, for example nicknames are
3498 * Fixed a bug in server with channel message sending. It put
3499 wrong ID type as destination ID. The affected file
3500 silcd/packet_send.c.
3502 * silc_idcache_del_by_context now deletes from all hash tables
3503 by context. Affected file lib/silccore/idcache.c.
3505 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3507 * Changed the client library to use the new ID Cache interface.
3508 Changes around the source tree.
3510 * Added silc_hash_table_rehash_ext to rehash with specific
3511 hash function. Affected file lib/silcutil/silchashtable.[ch].
3513 * Added silc_hash_string_compare to compare two strings in the
3514 hash table. Affected file lib/silcutil/silcutil.[ch].
3516 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3518 * Added new function silc_idcache_del_by_context into the
3519 lib/silccore/idcache.[ch].
3521 * Changed the server's ID list routines to use the new ID Cache
3522 interface. Changes around the source tree.
3524 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3526 * Added silc_hash_table_del[_by_context]_ext functions in to the
3527 lib/silcutil/silchashtable.[ch].
3529 Removed silc_hash_table_find_all* routines and added new
3530 silc_hash_table_find_foreach to replace them.
3532 Added silc_hash_table_replace_ext function as extended
3533 replacing function. Separated the simple hash table interface
3534 from the extended hash table interface in the file
3535 lib/silcutil/silchashtable.h.
3537 * Fixed minor bugs and changed it to use some of the new
3538 hash table functions in lib/silccore/idcache.c
3540 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Added new function silc_hash_table_find_all to return all keys
3543 in the hash table by the specified key. As the hash table is
3544 collision resistant it also makes it possible to have several
3545 duplicate keys in the hash table. This function may be used to
3546 find all of the keys from the hash.
3548 Added user_context arguments to the SilcHashFunction,
3549 SilcHashCompare and SilcHashDestructor to deliver user specified
3552 Added new fuctions silc_hash_table_find[_all]_ext to do
3553 extended lookup with specified hash and compare functions and
3554 specified user contexts.
3556 Added new function silc_hash_table_add_ext to add the key
3557 with specified hash function and user context.
3559 Added new function silc_hash_table_foreach to traverse all
3560 entrys in the hash table. Added SilcHashForeach callback
3563 Added new function silc_hash_table_del_by_context to delete
3564 the entry only if the context associated with the key matches.
3566 Affected files are lib/silcutil/silchashtable.[ch].
3568 * Removed silc_hash_[server/client/channel]_id and added just
3569 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3570 silc_hash_id_compare to compare two ID's using as the hash table
3571 comparison function. Added also silc_hash_data to hash
3572 binary data and silc_hash_data_compare to compare it.
3574 * Removed silc_idlist_find_client_by_hash as it is not needed
3575 anymore. Affected file silcd/idlist.[ch].
3577 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3578 to use internally the SilcHashTable. The new ID Cache is a lot
3579 faster than the old one. Some of the ID Cache interface was also
3580 rewritten and obsolete and stupid functions were removed.
3582 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3584 * Added entry_count field to the SilcHashTable to keep the number
3585 of the entries in the table. Implemented the function
3586 silc_hash_table_rehash. Added new function
3587 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3589 Fixed a minor bug in silc_hash_table_free.
3591 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3592 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3593 into the lib/silcutil/silcutil.[ch].
3595 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3597 * Implemented a collision resistant hash table into the
3598 lib/silcutil/silchashtable[ch]. See the header and the source
3599 for the SilcHashTable API.
3601 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3603 * Merged dotconf version 1.0.2 into lib/dotconf.
3605 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3607 * Do not compile anything in lib/silcsim/* if the SIM support
3608 is not enabled. The tree should now compile without problems
3611 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Compiled the SILC under cygwin. Compiled and tested briefly
3614 without problems. More tests needed. The SIMs didn't compile
3617 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3619 * Fixed possible crash in silc_get_username in the
3620 lib/silcutil/silcutil.c.
3622 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3624 * Fixed a va_arg in silc/client_ops.c.
3626 * Oops, RC5 routines were named AES and caused some problems
3627 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3629 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3631 * Added new SilcIDIP structure into the lib/silccore/id.h and
3632 replaced the old `ip' fields from all SILC ID's to that type.
3633 This is a step towards IPv6 support.
3635 The silc_id_get_len takes now the ID as an extra argument.
3636 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3637 both IPv4 and IPv6 based ID's.
3639 The affected files are lib/silccore/id.[ch] and other files
3640 around the tree using these routines.
3642 * Removed the ID length arguments in server from various
3643 silc_server_send_notify_* routines -> they are not needed
3646 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * Fixed memory leak in silc_encode_pem_file in the file
3649 lib/silcutil/silcutil.c.
3651 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3653 * Check minor version as well in the SKE. Affected files are
3654 silcd/protocol.c and lib/silcclient/protocol.c.
3656 * Added --identifier option to the server so that an identifier
3657 can be when creating the public key for the server. Affected
3658 file is silcd/silcd.c.
3660 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3661 lib/silccrypt/silcpkcs.c.
3663 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3665 * Register default ciphers and stuff when using -C option with
3666 the server. Affected file sildc/silcd.c.
3668 * Put back the servers public key filename format, it is better
3669 than the new one. For now, the client keys are saved with the
3670 new filename format. The affected file silc/client_ops.c.
3672 * Implemented the Cipher API for the rest of the ciphers that
3673 did not implement it or implemented it the wrong way.
3675 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3677 * Register default ciphers and stuff when using the -S option
3678 in the client. Affected file silc/silc.c. Same also when
3679 creating new key pair with -C option.
3681 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3683 * Fixed the silc_verify_public_key client operation function to
3684 save the public keys differently. The fingerprint is now
3685 used as filename and not the hostname. This way also the
3686 client keys are saved uniquely and not with hostnames. The
3687 affected file is silc/client_ops.c.
3689 * Trimmed the silc_hash_fingerprint function to remove extra
3690 whitespaces from the end of the fingerprint. The affected
3691 file is lib/silccrypt/silchash.c.
3695 * Added silc_cipher_register_default function to register all
3696 default ciphers. It can be used when configuration files
3697 does not exist and the application does not want any specific
3698 ciphers in any specific order.
3700 The SilcDList is now used as silc_cipher_list dynamically
3701 allocated cipher list. Removed the static list all together
3702 and now all ciphers must be allocated to the dynamic list.
3703 The silc_cipher_alloc routine was changed to check only the
3706 All silc_cipher_* routines that used to return int returns
3709 The affected files lib/silccrypt/silccrypt.[ch].
3711 * The same thing was done to silc_hash_* as for silc_cipher_*
3712 routines. Affected files lib/silccrypt/silchash.[ch].
3714 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3715 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3716 Added also silc_pkcs_[un]register[_default] functions.
3717 Removed the data_context from the PKCS API.
3719 * Added silc_hmac_register_default function to register default
3720 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3721 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3722 to unregister all hmacs at once.
3724 * Register the default ciphers, hash functions, PKCSs and HMACs
3725 if client's configuration file does not exist. The affected
3728 * The client did not load the hash functions from the SIM
3729 modules at all. Added support for this. Affected file is
3730 silc/clientconfig.c.
3732 * When decoding public key with silc_pkcs_public_key_decode, check
3733 the supported algorithm only if PKCS are registered. Affected
3734 file lib/silccrypt/silcpkcs.c. The same was done with the
3735 silc_pkcs_private_key_decode.
3737 * Fixed the SILC List routines to keep the list always in order.
3738 It used to change the list's order when traversing the list but
3739 not it preserves the order. Affected file lib/trq/silclist.h.
3741 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3743 * Added the client library to use the SilcSocketConnection's
3744 reference counter (by silc_socket_dup) to prevent the bug that
3745 the socket object may be freed underneath async operation.
3747 * The name resolv library checking fixes in the configure.in.pre.
3750 * Created new version of the protocol drafts for future
3751 development. The -03 drafts are the ones that will be changed
3752 in the trunk now and the -02 will remain as they are.
3754 * Send list of CUMODE notifys to the router when announcing
3755 the channel users to the router. Affected file silcd/server.c.
3756 If the router receiving channel founder CUMODE for a channel
3757 that already has channel founder it will send CUMODE notify
3758 to the sender to remove the channel founder rights from the
3759 announced client. Affected file silcd/packet_receive.c.
3761 * The CUMODE notify may now use Server ID as well as the entity
3762 who changes the mode. Updated protocool specs.
3764 * Updated INSTALL and README files.
3766 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3768 * New web pages in the http://silc.pspt.fi. The pages was
3773 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Implemented the [DenyConnectin] config section in the server.
3776 Added silc_server_config_denied_conn to check whether incoming
3777 connection is denied. Affected file silcd/serverconfig.[ch].
3779 * Do not check the ports when checking the incoming configuration
3780 data if the port is 0, meaning any. Affected file is
3781 silcd/serverconfig.c.
3783 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Fixed buffer overflow in silc_string_compare in the file
3786 lib/silcutil/silcutil.c.
3788 * Fixed double free in silc_server_command_leave in the file
3791 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3793 * Fixed the version checking in the server. Affected file is
3796 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3798 * Fixed the configuration data fetching when accepting new
3799 connections in the server. Affected file silcd/server.c.
3801 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3803 * Added `sender_entry' argument to the function
3804 silc_server_packet_relay_to_channel so that we can check
3805 whether some destination actually belongs to the same route
3806 the sender belongs (ie, we must not resend the packet to the
3807 sender). Affected file silcd/packet_send.[ch].
3809 * Added `servername' field to the SilcClientEntry in the server
3810 to hold the name of the server where client is from. Affected
3811 file is silcd/idlist.h.
3813 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Moved the channel message encrypting in the router betwen
3816 router connections from silc_server_channel_message to the
3817 silc_server_packet_relay_to_channel since we want to check
3818 whether we have anybody channel before encrypting anything.
3819 Affected files silcd/packet_[receive/send].c.
3821 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3823 * Fixed the [AdminConnection] server config section to support
3824 multiple entries. Affected file silcd/serverconfig.c.
3826 * Added support into the server to check the validity of the
3827 incoming connection before executing any KE or authentication
3830 * The connection configuration is now saved to the KE and
3831 connection auth protocol contexts and not fetched anymore in
3832 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3834 * The local hosts listenning address and port is also resolved
3835 now when starting the server. We want to have the socket object
3836 to include the real address and port for the listener. Added
3837 new function silc_net_check_local_by_sock into the files
3838 lib/silcutil/silcnet.[ch].
3840 * Fixed a broadcast bug in server -> do not broadcast if we
3843 * Fixed a routing bug. Do not route broadcast packets ever.
3844 Broadcast packets must be processed always and not routed since
3845 they may be destined to some other host than yourself and thus
3846 would get routed without no good reason. Affected file is
3849 * Added function silc_server_config_is_primary_route to check
3850 whether primary router connection has been configured (a router
3851 configuration that we are initiating). If there is not, we
3852 will assume that there is only two routers in the SILC network
3853 and we will use the incoming router connection as our primary
3854 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3856 * Changed the order of the broadcasting. Broadcast _after_ the
3857 packet has been processed not before. Affected file is
3860 * Fixed a [ClientConnection] parsing bug. The port was never
3861 parsed correctly thus resulting to port 0. Affected file
3862 silcd/serverconfig.c.
3864 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3865 argument and did not set the broadcast packet flag. Affected
3866 file silcd/packet_send.c. Fixed same bug in the function
3867 silc_server_send_notify as well.
3869 * If we receive NEW_ID packet for our own ID in the server, ignore
3872 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * Removed the nickname from the Private Message Payload.
3877 Updated the code and the protocol specs.
3879 * Updated protocol specs for submitting to the IETF.
3881 * Tweaked the Random Number Generator a bit. Affected file
3882 lib/silccrypt/silcrng.c. Exported a new function
3883 silc_rng_[global]_add_noise which can be used to add more
3886 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3888 * Do not parse packets with different timeout when protocol
3889 is active -> may cause problem with rekey. Affected file
3892 * When server receives signoff notify it must not create
3893 new channel key if the client is on any channels since the
3894 sender of the signoff notify will create it.
3896 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3898 * Added printing of error messages during SKE protocol from the
3899 failure packet sent by server during SKE. Affected file
3902 * Removed the client's failure_callback handling with timeout
3903 and handle it immediately when received.
3905 * The SKE library returned wrong type in SUCCESS and FAILURE
3906 packets. They must be 32 bit MSB not 16 bit MSB.
3908 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3910 * Ok, rewrote the logic of the re-key and now it seems to work.
3911 I tested it on high traffic with frequent re-keys without
3912 problems. Added hmac_receive (and renamed hmac to hmac_send)
3913 in SilcClientConnection in lib/silcclient/client.h and
3914 in SilcIDListData in silcd/idlist.h. Also, removed the
3915 SilcPacketParserContext's cipher and hmac fields as they are
3916 not needed anymore and actually caused some problems when
3917 the ciphers and hmac's changed underneath the packet parser.
3919 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3921 * If re-key protocol is active then process the incoming packets
3922 synchronously since we must assure that icoming packets encrypted
3923 with the old key is processed before the new keys is set to
3924 use. This is true other packets than for REKEY packets.
3925 Affected file silcd/server.c. The same was done to client library
3926 as well, affected file lib/silcclient/client.c.
3928 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3930 * Fixed bug in client and server to accept the force send if
3931 the packet is send from silc_[server/client]_packet_process
3932 function. Otherwise the packets are never delivered, oops.
3934 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3936 * Disable force sending of packets when REKEY protocol is active.
3937 We must assure that no packet is sent directly when rekey is
3938 performed. All packets must be sent through packet queue.
3939 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3940 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3941 function is silc_[server/client]_packet_send_real to check
3944 * Replaced the SIM paths from example config files to
3945 /usr/local/modules. Also, make install creates now
3946 /usr/local/silc/logs directory to hold all the SILC server
3949 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3951 * Made the configure.in.pre work on Solaris. Patch by salo.
3953 * Made all ciphers compatible with non-x86 machines. Defined
3954 CBC mode macros into lib/silccrypt/ciphers_def.h.
3956 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3958 * Fixed the make install.
3960 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3962 * When MAC computation fails the silc_packet_decrypt returned 0
3963 even though it was supposed to return -1. Fixed this. The
3964 affected file is lib/silccore/silcpacket.c.
3966 * Do not replace the config files in /etc/silc (in make install)
3967 if they already exist. Affected file ./Makefile.am.
3969 * Do not send re-key packets immediately but through packet queue.
3970 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3972 * Changed silc_net_check_host_by_sock to return FALSE if the
3973 IP/DNS could not be resolved. Though, it returns the IP address
3974 now even if it could not resolve it (but returns also FALSE).
3975 Affected file lib/silcutil/silcnet.[ch].
3977 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * Added silc_pkcs_decode_identifier to decode the public key's
3980 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3981 Added also silc_pkcs_free_identifier. Added also new context
3982 SilcPublicKeyIdentifier.
3984 * Added -S option to the silc client. It is used to dump the
3985 contents of the specified public key file.
3987 * Changed the PKCS api to return the public key length when
3988 setting the public key.
3990 * Fixed a fatal bug in the public and private key file loading.
3991 Affected file lib/silccrypt/silcpkcs.c.
3993 * Execute the packet parsing for client with zero (0) timeout
3994 if the protocol is active. Affected file silcd/server.c.
3996 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Made the key generation options to the silcd program. Added
3999 -C option, equivalent to client's option.
4001 * Added new [ServerKeys] config section to the server. It
4002 configures the server's public and private key.
4004 * Defined generic Public Key Payload into the protocol
4005 specification to send specific type of public keys and
4008 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4009 public key or certificate.
4011 * Implemented the GETKEY command to the server and to the
4012 client library and on user interface.
4014 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4016 * Made preliminary `make install' work.
4018 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4020 * Added SilcServerRekey context into silcd/idlist.h.
4022 * Added the PFS support as defined in the specification to the
4023 SKE protocol. Affected files lib/silcske/*.c.
4025 * Added `ske_group' field to the SilcServerRekey context to hold
4026 the number of the SKE group that is used with PFS in re-key.
4027 Affected file silcd/idlist.h.
4029 * Added PFS re-key support to the server. Affected file is
4032 * Added silc_protocol_cancel to cancel execution of the next
4033 state of the protocol. Affected file is
4034 lib/silccore/silcprotocol.[ch].
4036 * Added the re-key support with and without PFS to the client
4037 library. Re-key is performed once in an hour, by default.
4039 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4040 Added silc_client_rekey_callback and silc_client_rekey_final.
4041 Affected files are lib/silcclient/protocol.[ch] and
4042 lib/silcclient/client.[ch].
4044 * Removed the `hmac_key' and `hmac_key_len' fields from the
4045 SilcClientConnection structure; not needed. Affected file is
4046 lib/silcclient/client.h.
4050 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4052 * Do not ask whether user wants to use the negotiated private key
4053 for private messages, just use it. Affected file is
4054 silc/local_command.c.
4056 * Added `send_enc_key' and `enc_key_len' fields to the
4057 SilcIDListData structure since they are needed in the re-key
4058 phase. Affected file is silcd/idlist.[ch].
4060 * Implemented the simple re-key protocol into the server.
4061 Affected files silcd/server.c and silcd/protocol.[ch]. The
4062 re-key will be performed once in an hour, by default.
4064 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4065 Added silc_server_rekey, silc_server_rekey_callback and
4066 silc_server_rekey_final.
4068 * Removed Tunneled flag from the protocol. Updated the code
4069 and the specifications.
4071 * Adde `pfs' field to the SilcIDListData to indicate whether
4072 the PFS is to be performed in the re-key. Affected file is
4075 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4077 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4078 int64 of at least the xintXX size. If void * is less that 4
4079 bytes uint32 * will be used. Defined bool as boolean.
4081 * Changed _ALL_ unsigned long and unsigned int to uint32,
4082 unsgined short to uint16 in the source tree.
4084 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4085 not handle clients that has entry->data.registered == FALSE.
4086 They are not in the network anymore. Affected file is
4089 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4091 * Implemented the sending of the SERVER_SIGNOFF notify in the
4092 server. Affected file is silcd/server.c.
4094 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4095 Added also silc_notify_payload_encode_args into the
4096 lib/silccore/silcnotify.[ch].
4098 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4099 Affected file silcd/packet_receive.c.
4101 * Implemented the SERVER_SIGNOFF notify handling in the client
4102 library. Affected file lib/silcclient/client_notify.c. Also,
4103 implemnted the printing of the SERVER_SIGNOFF info to the
4104 application. Affected file silc/client_ops.c.
4106 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4107 if the deleting was successful. Affected file silcd/idlist.[ch].
4109 * Added support for public key authentication in the connection
4110 authentication protocol in the client library. Affected file
4111 lib/silcclient/protocol.c.
4113 * Changed the server's silc_idlist_get_clients_by_* interface
4114 to support already allocated array so that new entries may be
4115 added to pre-allocated array. Affected file silcd/idlist.[ch].
4116 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4117 and command replies.
4119 * All command reply functions in the server now calls the
4120 pending command callback even if error occured. This way the
4121 error will be delivered to the client as well. Affected files
4122 silcd/command.c and silcd/command_reply.c.
4124 * Fixed INFO command to return local server's info if no server
4125 was provided. Affected file lib/silcclient/command.c.
4127 * Removed RESTART command for good. Updated the code and the
4130 * Rewrote parts of the task system. It is a bit simpler now.
4131 Removed unsued task priorities. The affected files are
4132 lib/silcutil/silctask.[ch].
4134 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4136 * Moved the USERS printing from the library to the application.
4137 Affected files lib/silcclient/command.c and silc/client_ops.c.
4139 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4143 * Added channel key re-key support. The re-key is perfomed
4144 only by the router and is done once in an hour. Added `rekey'
4145 field to the SilcChannelEntry in the server. Affected files
4146 silcd/server.c and silcd/idlist.h.
4148 * Added silc_task_unregister_by_context into the file
4149 lib/silcutil/silctask.[ch].
4151 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4153 * Added SILC_UMODE_GONE mode to indicate when the client is not
4154 present in the SILC network. Added also support to the local
4155 command AWAY that will set this mode. Added support of showing
4156 "xxx is gone" in WHOIS command. The USERS command shows the
4157 gone status as well.
4159 * Fixed setting server and router operator privileges in the
4160 server's UMODE command. Affected file silcd/command.c.
4162 * Merged the SKE KE1 and KE2 payloads into one payload. The
4163 new KE payload is equivalent to the old KE2 payload.
4165 Cleaned up the SKE Start Payload parsing. It now uses the
4166 simple buffer unformatting to do the parsing. A lot faster
4169 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4170 to the SKE that is used to indicate whether both of the SKE
4171 parties should perform authentication. By default only the
4172 responder performs authentication. By setting this flag also
4173 the initiator must do authentication. By default it is unset
4174 since in normal SKE case, client to server connection, only
4175 the responder should do authentication. When doing SKE between
4176 two clients both should perform authentication. Updated the
4177 code and the protocol specs.
4179 * A little fix to IDENTIFY command in the server. Search the
4180 client first by hash not nickname. Affected file is
4183 * Fixed the silc_client_close_connection to support closing
4184 the client to client connections wihtout deleting too much
4185 data. Affected file lib/silcclient/client.c.
4187 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4188 are received if protocol used to be active but is not anymore
4189 the application would crash due to NULL pointer dereference.
4190 Affected files silcd/server.c and lib/silcclient/client.c.
4192 * Added `hash' field to the SilcClientConnection to include
4193 the hash function negotiated in the SKE protocol.
4195 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4196 to set the channel founder authentication data. A client can
4197 claim the founder rights later by providing the authentication
4198 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4199 This way the channel founder can regain the channel founder
4200 privileges even it is left the channel. This works only on
4201 local server and the client must be connected to the same
4202 server to be able to regain the founder rights. Updated the
4203 protocol specs accordingly.
4205 Added support to the CMODE command in the client to set the
4206 founder auth data. Read the README to see how to set it.
4208 Added support to the CUMODE command to claim the founder
4209 rights. Read the README to see how to do it.
4211 Added support for the founder authentication to the Channel
4212 Entry in the server. Affected file silcd/idlist.h.
4214 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4215 server's CMODE command. Affected file silcd/command.c.
4217 * Added the following new functions into lib/silccore/silcauth.[ch]:
4218 silc_auth_get_method and silc_auth_get_data.
4220 * The server now saves the remote hosts public key to the
4221 SilcIDListData pointer. Affected file silcd/protocol.c.
4223 * The normal server now does not remove the channel entry from
4224 the cache if the founder authentication data is set. It used
4225 to remove it if the founder was the last one on the channel on
4226 the server and left the channel. The auth data is saved and
4227 if the channel is re-joined later the old entry is used with
4228 the old auth data. Affected files silcd/command_reply.c and
4231 * Removed the `pkcs' field from the SilcIDListData structure
4232 in the server; it is not used. Affected file silcd/idlist.h.
4234 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4236 * Fixed packet processing on slow links. Partial packets were
4237 never re-processed because the incoming data buffer was cleared
4238 by the application. Application must not directly clear the
4239 sock->inbuf, the packet processing routines handle it. Fixed
4240 this in client library and in server.
4242 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4244 * Fixed the WHOIS and IDENTIFY send reply function to really
4245 check whether to send list or just one entry. Affected file
4248 * Cleaned up the LEAVE command's channel key distribution. The
4249 affected file silcd/command.c.
4251 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4252 can enforce the channel mode as well. In that case the ID
4253 includes the ID of the server. The code now enforces the
4254 mode change if the router have different mode than the server.
4256 * The notify client operation with CMODE_CHANGE notify can now
4257 return NULL client_entry pointer if the CMODE was not changed
4258 by client. Application must check for this.
4260 * Added <Server ID> argument to INFO command to support server
4261 info fetching by Server ID.
4263 * Added silc_server_announce_get_channel_users to get assembled
4264 packets of channel users of the specified channel. Affected
4265 file silcd/server.[ch].
4267 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4268 was freed underneath the ID Cache.
4270 * Re-announce clients when the server received CHANNEL_CHANGE
4271 notify from the router. Affected file silcd/packet_send.c.
4273 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4275 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4276 crashed since it did not handle the fact that there is no cipher
4277 called "3" and didn't check the error condition. Now fixed.
4279 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4280 flag. It can be used to send message requests.
4282 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4284 * Implemented the RESTART command in the client.
4286 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4287 notice type messages. Added notice printing to the user
4290 * The channel keys are not re-generated if the channel's mode
4291 is PRIVKEY, ie private key on the channel exists. Affected
4292 files silcd/server.c and silcd/command.c.
4294 * Fixed a little bug in channel message delivery when channel
4295 private keys are set in the server. Affected file is
4296 silcd/packet_send.c.
4298 * Changed the setting on channel->on_channel = TRUE from the
4299 silc_client_save_channel_key to the JOIN command reply. The
4300 key payload is not received if the private channel key is set.
4301 Affected file lib/silcclient/command_reply.c and the
4302 lib/silcclient/client_channel.c.
4304 * When the CMODE_CHANGE notify is sent and the channel private
4305 key mode is removed the channel key must be re-generated in
4306 other cells as well. Added this support for the router in the
4307 silcd/packet_receive.c.
4309 * Added new local command NOTICE to send notice message on
4310 channel. Affected file silc/local_command.[ch].
4312 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Added new local command ME to the client. It is used to send
4315 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4316 some action. Affected file silc/local_command.[ch].
4318 * Changed channel_message and private_message client operations
4319 to deliver the message flags to the application. Added also
4320 the `flags' arguments to the silc_client_send_channel_message
4321 and silc_client_send_private_message functions. Affected file
4324 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4326 * Redefined the Private Message Payload to support private message
4327 keys and to support the new private message flags. Updated
4328 the protocol specs. Flags makes it possible to have for example
4329 CTCP style messages.
4331 * Added new type SilcPrivateMessagePayload and defined an API
4332 for it in the lib/silcclient/silcprivate.[ch].
4334 * Tested private message private keys successfully. Tested the
4335 private message key set, unset and list commands with the new
4338 * Redefined the Channel Message Payload to include the channel
4339 message flags (equal with private message flags) to support
4340 for example CTCP style messages.
4342 * Defined some of the message (for channel and private message)
4343 flags. Updated the protocol specs and added the flags to the
4344 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4346 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4348 * Added SilcKeyAgreementStatus type to the key agreement routines
4349 to indicate the current status and error if one occured.
4350 The status types are defined in the lib/silcclient/silcapi.h.
4352 * Added new local command KEY that is used to set and unset private
4353 keys for channels, set and unset private keys for private messages
4354 with remote clients and to send key agreement requests and
4355 negotiate the key agreement protocol with remote client. The
4356 key agreement is supported only to negotiate private message keys,
4357 it currently cannot be used to negotiate private keys for channels,
4358 as it is not convenient for that purpose.
4360 * Fixed a minor pending callback setting bug in the function
4361 silc_client_get_client_by_id_resolve, now the function works.
4362 Affected file lib/silcclient/idlist.c.
4364 * Added function silc_net_get_local_port to get local bound
4365 port by socket. Added to lib/silcutil/silcnet.[ch].
4367 * Added `sockets' and `sockets_count' fields to the SilcClient
4368 object. They hold the sockets of the listenning sockets in
4369 the client. Listenning sockets may be for example the key
4370 agreement server. Affected file lib/silcclient/client.[ch].
4371 Added functions the silc_client_add_socket and the
4372 silc_client_del_socket. They are exported to the application
4375 * Added ~./silc/clientkeys to support other client's public keys.
4377 * Renamed verify_server_key client operation to verify_public_key
4378 and added one argument to indicate the type of the connection
4379 (server, client etc.).
4381 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * Added silc_server_connection_auth_request to handle the
4384 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4385 silcd/packet_receive.[ch].
4387 * Added silc_server_send_connection_auth_request into the
4388 silcd/packet_send.c to send the connection auth request packet.
4390 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4393 * Fixed the public key authentication in responder side in the
4394 server. The `auth_data' pointer includes the SilcPublicKey
4395 not the path to the public key. Affected file silcd/protocol.c.
4397 * Implemented the public key authentication in the initiator side
4398 in the server. Affected file silcd/protocol.c.
4400 * Removed the [RedirectClient] config section from the server
4401 configuration. Is not needed and I don't want to implement it.
4403 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4405 * Cleaned up the CMODE command in the server. It now works
4406 correctly and supports all the modes defined in the protocol.
4407 Affected file is silcd/command.c.
4409 * Added `hmac_name' field to the SilcChannelEntry in the server
4410 to hold the default HMAC of the channel. It can be set when
4411 creating the channel (with JOIN command). Affected files
4414 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4415 type to indicate the change of the current cipher and hmac
4416 on the channel. Client can safely ignore the <cipher> argument
4417 (if it chooses to do so) since the CHANNEL_KEY packet will
4418 force the channel key change anyway. The <hmac> argument is
4419 important since the client is responsible of setting the new
4420 HMAC and the hmac key into use.
4422 * Fixed the CMODE command in the client library as well.
4424 * Tested CMODE command in router environment successfully.
4426 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4428 * Show the version of the remote client (or server) when connecting
4429 to the server. It is logged to the log file. Affected file
4430 is silcd/protocol.c.
4432 * Fixed the KILLED notify handling in the client library. The
4433 client must be removed from all channels when receiving the
4436 Also, do not remove the client entry when giving the KILL
4437 command but when the KILLED notify is received.
4439 * Removed silc_idlist_find_client_by_nickname from the server.
4440 Not needed anymore. Affected files silcd/idlist.[ch].
4442 * Implemented the CHANNEL_CHANGE notify type handling to the
4443 server. Affected file silcd/server.c.
4447 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4449 * Added silc_server_send_notify_invite to send the INVITE
4450 notify between routers.
4452 * Implemented the INVITE command correctly to the server.
4454 * Implemented the INVITE notify type handling in the server.
4456 * Implemented the INVITE command to the client library and on the
4459 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4461 * Added function silc_server_get_client_resolve to find the
4462 client entry by ID from all ID lists and then resolve it
4463 (using WHOIS) if it cannot be found. Affected file is
4466 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4468 * Implemented the BAN command to the client library.
4470 * The JOIN command in the server now checks the invite list
4473 * Changed the silc_command_reply_payload_encode_va and the
4474 silc_command_payload_encode_va to support that if argument is
4475 NULL it ignores and checks the next argument. Affected file
4476 lib/silccore/silccommand.c.
4478 * Added silc_server_send_notify_ban to send the BAN notify
4479 type between routers.
4481 * Chaned the silc_notify_payload_encode to support that if
4482 argument is NULL it ignores and checks the next argument.
4483 Affected file lib/silccore/silcnotify.c.
4485 * Tested ban lists in router environment successfully.
4487 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4489 * Implemented BAN command to the server, in silcd/command.[ch].
4491 * Removed the BAN and INVITE_LIST modes from the CMODE command
4494 * Added function silc_string_match to regex match two strings.
4495 Affected files lib/silcutil/silcutil.[ch].
4497 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4499 * Redefined parts of the SilcChannelEntry in the server to support
4500 the new ban and invite lists.
4502 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Redefined the INVITE command. The same command can be used to
4505 invite individuals to the channel but also to manage the invite
4506 list of the channel (to add to and remove from the invite list).
4507 Updated the protocol specs.
4509 * Added new command SILC_COMMAND_BAN that can be used to manage
4510 the ban list of the channel. Updated the protocol specs.
4512 * Removed the channel modes: the SILC_CMODE_BAN and the
4513 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4514 in the CMODE command. The equivalent features are now available
4515 using INVITE and BAN commands. Updated the protocol specs.
4517 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4518 in the network about change in the current ban list. The notify
4519 type is not used by the client.
4521 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4522 support the invite lists.
4524 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4526 * Added new function silc_string_regexify that converts string
4527 including wildcard characters into regex string that can
4528 be used by the GNU regex library. Added into the file
4529 lib/silcutil/silcutil.[ch].
4531 Added silc_string_regex_combine to combine to regex strings
4532 into one so that they can be used as one regex string by
4533 the GNU regex library. Added into the file
4534 lib/silcutil/silcutil.[ch].
4536 Added silc_string_regex_match to match two strings. It returns
4537 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4539 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4541 * Imported GNU regex to the soruce tree into lib/contrib.
4542 Fixed some compiler warning from the regex.c.
4544 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4546 * Fixed MOTD command in the server to work in router environment.
4548 * Fixed the MOTD command in the client library to support
4549 the server argument in the command.
4551 * Added `nickname_len' argument to the silc_idlist_add_client
4552 in the server, as the `nickname' argument may be binary data
4555 * Added silc_idlist_get_channels to return all channels from
4558 * Implemented LIST command to the server. Affected file is
4561 * Implemented the LIST command to the client library and on the
4564 * Added [<user count>] argument to the LIST command reply.
4565 With private channels the user count is not shown.
4567 * Updated TODO and README.
4569 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4571 * The client entry's data.registered must be TRUE even with
4572 global client entry on global client list. The data.registered
4573 is used to check whether the client is anymore in the network,
4574 for example with WHOWAS command so it must be valid.
4576 * Fixed the WHOWAS command in the server. It now actually works
4577 in router environment. Added function into silcd/command_reply.c
4578 silc_server_command_reply_whowas_save.
4580 * Added silc_idlist_purge function to the silcd/idlist.c
4581 to periodically purge the ID Cache.
4583 * Fixed INFO command in the server. It works now in router
4584 environment. Added <server name> argument to the INFO command
4585 reply. Updated the protocol specs.
4587 * Fixed minor bug in silc_idcache_purge to not purge if the
4588 expire value is zero.
4590 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4591 they were buggy because of the WHOWAS information.
4593 * Fixed local command MSG to handle the async resolving of
4594 the remote client properly. It used to fail the first MSG.
4595 Affected file silc/local_command.c.
4597 * Added `data_len' field to SilcIDCache context.
4599 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4601 * Update TODO. Todo in commands in the server.
4603 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4606 used by routers as broadcast packet to inform other routers
4607 about the changed user mode.
4609 Implemented the notify handling in the server. Affected file is
4610 silcd/packet_receive.c. Added the function
4611 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4613 * Added new generic Channel Payload and deprecated the New Channel
4614 Payload. The New Channel Payload is now the generic Channel
4617 * Added new argument `mode' to the silc_server_send_new_channel
4618 as it is required in the Channel Payload now.
4620 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4621 and created a new and real SilChannelPayload to represent the
4622 new generic Channel Payload. Implemented the encode/decode
4623 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4625 * Added silc_server_get_client_channel_list to return the list
4626 of channels the client has joined for WHOIS command reply.
4627 Affected file silcd/server.[ch].
4629 * Implemented the channel list sending in the WHOIS command reply
4630 in server and in the client.
4632 Implemented the channel list displaying on the user interface
4633 as well. Affected file silc/client_ops.c.
4635 * Added silc_channel_payload_parse_list to parse list of Channel
4636 Payloads. It returns SilcDList list of SilcChannelPayloads.
4637 Client for example can use this function to parse the list of
4638 channels it receives in the WHOIS command reply. The caller
4639 must free the list by calling silc_channel_payload_list_free.
4640 Affected files lib/silccore/silcchannel.[ch].
4642 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4644 * Added one new argument <user mode> to the WHOIS command reply
4645 to return the mode of the user in SILC. Updated the protocol
4648 Implemented it to the server and client.
4650 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Fixed the mode printing on the user interface on joining.
4653 Affected file silc/client_ops.c.
4655 * Implemented the UMODE command and user modes in general to the
4656 client library and to the user interface.
4658 * Implemented the UMODE command to the server.
4660 * The server now sends UNKNOWN_COMMAND error status if client sends
4661 unknown command. Affected file silcd/command.c.
4663 * All server commands now handle the command identifier the right
4664 way when sending the command reply to the client. The client can
4665 use to identify the command replies with the identifier.
4667 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4669 * Added silc_server_get_client_route to resolve the route to
4670 the client indicated by the client ID. Affected file is
4673 * Added silc_server_relay_packet as general function to relay
4674 packet to arbitrary destination. This deprecates functions
4675 like _send_private_message_key, _relay_notify etc. Affected
4676 file is silcd/packet_send.[ch].
4678 Removed silc_server_send_key_agreement,
4679 silc_server_send_private_message_key and
4680 silc_server_packet_relay_notify functions from the file
4681 silcd/packet_send.[ch].
4685 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4686 server. Affected file silcd/packet_receive.[ch].
4688 * Implemented the KILL command to the client. Implemented the
4689 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4690 Affected files lib/silcclient/command[_reply].c and
4691 lib/silcclient/client_notify.c. Implemented the KILL notify
4692 printing in the user inteface.
4694 * Fixed a lot silc_parse_nick memory leaks from the client
4695 library in the file lib/silcclient/command.c.
4697 * Changed the silc_server_send_notify_on_channels's `sender'
4698 argument from SilcSocketConnection to SilcClientEntry to
4699 check the sender as entry and not as connection object and not
4700 to send to the client provided as argument. The affected file
4701 is silcd/packet_send.[ch].
4703 * The notify packets that are destined directly to the client used
4704 to not to be processed by the server. Now changed that and the
4705 server processes all notify packets. After relaying the packet
4706 to the client the notify packet is processed in the server.
4708 * The silc_server_free_client_data now checks whether there is
4709 pending outgoing traffic for the client and purges the data to
4710 the network before removing the client entry.
4712 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4715 an client is killed from the SILC Network. Updated the protocol
4718 Added new function silc_server_send_notify_killed to the
4719 silcd/packet_send.[ch].
4721 * Added function silc_server_packet_relay_notify to relay notify
4722 packets that are destined directly to a client. In this case
4723 the server does not process the notify packets but merely relays
4724 it to the client. Affected file silcd/packet_send.[ch].
4726 Added also silc_server_packet_process_relay_notify to check
4727 whereto relay the notify. Affected file is
4728 silcd/packet_receive.[ch].
4730 * Implemented the KILL command to the server.
4734 * Added the backup schema desgined last fall to the protocol
4735 specs for everyone to see. The specification is in the
4736 *-spec-xx.txt draft and the packet type definitions for the
4737 backup routers is in *-pp-xx.txt draft. Thusly, added also
4738 new packet type SILC_PACKET_CELL_ROUTERS.
4740 * A big security problem in the implementation discovered. The
4741 signoff of an client did not cause new channel key generation
4742 which it of course should've done. The channel keys must be
4743 always re-generated when client leaves (or signoffs) the channel.
4744 The silc_server_remove_from_channels funtion now handles
4745 the channel key re-generation.
4747 * Added `sender' argument to the silc_server_send_notify_on_channels
4748 to not to send the client provided as argument. Affected file
4749 silcd/packet_send.[ch].
4751 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4753 * Implemented OPER and SILCOPER commands into the server and
4756 * Added silc_auth_verify and silc_auth_verify_data to verify
4757 the authentication directly from the authentication payload.
4758 It supports verifying both passphrase and public key based
4759 authentication. Affected file lib/silccore/silcauth.[ch].
4761 * Added `hash' field to the SilcIDListData structure. It is the
4762 hash negotiated in the SKE protocol. Affected file is
4765 * Slight redesigning of the SilcAuthPayload handling routines.
4766 Do not send SilcPKCS but SilcPublicKey as argument.
4768 * Implemented the public key authentication support to the
4769 serverconfig. The public key is loaded from the provided path
4770 and saved as authentication data to void * pointer. Thus,
4771 changed the unsigned char *auth_data to void *auth_data;
4773 * Fixed SHUTDOWN command to send the reply before the server
4774 is shutdown. :) Affected file silcd/command.c.
4776 * Fixed fatal bug in CONNECT command. The hostname was invalid
4777 memory and server crashed. Affected file silcd/command.c.
4779 * Fixed fatal bug in CLOSE command. The server_entry became
4780 invalid but was referenced later in the command. Affected file
4783 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4785 * Fixed fatal bug in failure packet handling. Server ignored
4786 the failure and thus crashed when it came.
4790 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4792 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4793 that the command may be executed only once in (about) 2 seconds.
4794 The old SILC_CF_LAG flag is same but allows command bursts up
4795 to five before limiting.
4797 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4798 server code. Various commands now includes the CF_LAG_STRICT
4799 flag to disallow any kind of miss-use of the command.
4801 * Fixed the silc_buffer_unformat to not to allocate any data
4802 if the length of the data is zero. It used to allocate the
4803 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4805 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4807 * Changed the format of AdminConnection configuration section
4808 in the server. Added username of the admin to the format.
4809 Affected files silcd/serverconfig.[ch].
4811 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4812 to return admin configuration data by host, username and/or
4815 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4817 * Implemented WHOWAS command to the server. Added the functions:
4819 silc_server_command_whowas_parse,
4820 silc_server_command_whowas_send_reply,
4821 silc_server_command_whowas_from_client and
4822 silc_server_command_whowas_from_server
4824 * Added <Client ID> argument to the WHOWAS command reply. Updated
4825 the protocol specs accordingly.
4827 * Implemented WHOWAS command and command_reply to the client
4830 Implemented the WHOWAS printing on the user interface.
4832 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4834 * Added new argument to the WHOWAS command reply, the real name.
4835 It is an optional argument. Updated the protocol specs.
4837 * Added SilcIDCacheDestructor callback that is registered when
4838 the SilcIDCache is allocated. The callback is called when
4839 an cache entry in the ID Cache expires, or is purged from the
4840 cache. Added into lib/silccore/idcache.[ch].
4842 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4843 to destruct the client entries when the cache entry expires.
4844 Other ID Cache's in server and in the client library ignores
4847 * If the ID Cache entry's `expire' field is zero then the entry
4848 never expires. Added boolean `expire' argument to the
4849 silc_idcache_add function in the lib/silccore/idcache.[ch].
4850 If it is TRUE the default expiry value is used.
4852 * Added silc_server_free_client_data_timeout that is registered
4853 when client disconnects. By default for 5 minutes we preserve
4854 the client entry for history - for WHOWAS command.
4856 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4858 * Added support to the server to enforce that commands are not
4859 executed more than once in 2 seconds. If server receives
4860 commands from client more frequently, timeout is registered
4861 to process the commands. Affected file silcd/command.c.
4862 Added new function silc_server_command_process_timeout.
4864 * Changed NICK_NOTIFY handling in client library to check that
4865 if the client's nickname was changed, so there is no need to
4866 resolve anything from the server.
4868 * Removed error printing from the WHOIS and IDENTIFY commands.
4869 If error occurs then it is ignored silently in the client library.
4870 The application, however, may map the received error to
4871 human readable error string. The application currently maps
4872 the NO_SUCH_NICKNAME error to string.
4874 * Made the command status message public to the application. Moved
4875 them from lib/silcclient/command_reply.c to
4876 lib/silcclient/command_reply.h. The application can map the
4877 received command status to the string with the
4878 silc_client_command_status_message function.
4880 * Added check to the server to check that client's ID is same
4881 as the Source ID in the packet the client sent. They must
4884 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4886 * Added dist-bzip hook to the Makefile.am to make bzip2
4887 compressed distributions.
4889 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4891 * Server now enforces the maximum length for the nickname and
4892 the channel as protocol specification dictates. 128 bytes for
4893 nickname and 256 bytes for channel name.
4895 * Moved the WHOIS printing to the application. The client libary
4896 does not print out the WHOIS information anymore, the application
4897 must do it. Renamed silc_client_command_reply_whois_print to
4898 the silc_client_command_reply_whois_save.
4900 The client's idle time is also sent to the application now, and
4901 the idle is shown on screen.
4903 * Added silc_client_command_reply_identify_save to save the
4904 received IDENTIFY entries.
4906 * Do not check for channel private keys in message sending and
4907 reception if the channel does not have the PRIVKEY mode set.
4908 Affected file lib/silclient/client_channel.c.
4910 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4912 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4913 just surfaced after chaning the JOIN procedure.
4915 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4917 * Added silc_client_get_clients_by_list to get client entries
4918 from Client ID list, that is returned for example by JOIN
4919 and USERS command replies. The application should use this
4920 function for example when JOIN command reply is received to
4921 resolve the clients already on the channel (library does not
4922 do that anymore as USERS command reply is not used in the JOIN
4923 procedure anymore). Affected files lib/silcclient/silcapi.h and
4924 lib/silcclient/idlist.c.
4926 * JOIN command reply and USERS command reply returns now SilcBuffer
4927 pointers instead of unsigned char pointers when returning
4928 the client list and mode list.
4930 * Added <Client ID> argument to the JOIN command reply, mainly
4931 for the server to identify for which client the command was
4932 originally sent. Updated protocol specs accordingly.
4934 * Added SilcDlist private_key pointer to the SilcChannelEntry
4935 in the client to support the channel private keys. Affected
4936 file is lib/silcclient/idlist.h.
4938 * Added SilcChannelPrivateKey argument to the function
4939 silc_client_send_channel_message so that application can choose
4940 to use specific private ke if it wants to. If it is not provided,
4941 the normal channel key is used, unless private keys are set.
4942 In this case the first (key that was added first) is used
4943 as the encryption key.
4945 * Implemented the support for channel private key handling.
4946 Implemented the following functions:
4948 silc_client_add_channel_private_key,
4949 silc_client_del_channel_private_keys,
4950 silc_client_del_channel_private_key,
4951 silc_client_list_channel_private_keys and
4952 silc_client_free_channel_private_keys
4954 Affected file lib/silcclient/client_channel.c.
4956 * Added the support for the private keys in the channel message
4957 sending and encryption and in the message reception and
4958 decryption. Affected funtions are
4959 silc_client_send_channel_message and silc_client_channel_message.
4961 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4963 * Added SKE's key verify callback to the client library's
4964 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4966 * Removed the statement that server (or router) must send USERS
4967 command reply when joining to the channel so that the client
4968 knows who are on the channel. Instead, the client list and
4969 client's mode list is now sent in the JOIN command reply to the
4970 client who joined channel. This is better solution.
4972 * Added function silc_server_get_users_on_channel and function
4973 silc_server_save_users_on_channel to the silcd/server.[ch].
4975 * Removed function silc_server_command_send_users from the
4978 * Do not show topic on the client library anymore. The topic is
4979 sent in the command reply notify to the application and the
4980 application must show the topic now.
4982 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4984 * Added client searching by nickname hash into the IDENTIFY and
4985 WHOIS commands in the server as they were clearly missing from
4986 them. Affected file is silcd/command.c.
4988 * Fixed a bug in private message receiving in the client library.
4989 The remote ID was freed and it wasn't supposed, now it is
4992 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4994 * Minor fix to the channel payload; allocate the data area, as it
4995 needs to be of specific length.
4997 * If the key agreement port is zero then the operating
4998 system will define the bound port. Affected files are
4999 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5001 * Added new function silc_channel_payload_decrypt into the file
5002 lib/silccore/silcchannel.[ch].
5004 * Moved the channel message etc, check from silc_packet_decrypt
5005 to applications. The library calls now a generic
5006 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5007 when the packet is either normal or special. This was done to
5008 allow more wide range of checking that was not allowed when
5009 the code was in library. Now applications can do virtually any
5010 checks to the packet and return to the library the decision how
5011 the packet should be processed. Affected files are
5012 lib/silccore/silcpacket.[ch].
5014 Added silc_server_packet_decrypt_check to the server and
5015 silc_client_packet_decrypt_check to the client library.
5017 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5018 to send with specified source and destination information.
5020 * Channel message delivery between routers was broken after the
5021 channel key distribution was fixed earlier. The channel key
5022 was used be to distributed to other routers as well which is not
5023 allowed by the protocol. Now this is fixed and channel keys
5024 really are cell specific and the channel message delivery between
5025 routers comply with the protocol specification.
5027 * Fixed various commands in server to check also the global list
5028 for the channel entry and not just the local list. The affected
5029 file silcd/command.c.
5031 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5033 * Added assert()s to buffer formatting and unformatting routines
5034 to assert (if --enable-debug) when error occurs. Affected
5035 file: lib/silcutil/silcbuffmt.c.
5037 * Changed to auto-reconnect to check whether the remote host is
5038 router and register the re-connect timeout if it is. It used
5039 to check that whether we are normal server, but router must do
5040 auto-reconnect with another router as well. Affected file
5043 * Removed the [<key len>] option from CMODE command as the cipher
5044 name decides the key length, nowadays. See the defined ciphers
5045 from the protocol specification.
5047 * Added [<hmac>] option to the CMODE command to define the HMAC
5048 for the channel. Added SILC_CMODE_HMAC channel mode.
5050 * Added [<hmac>] option for the JOIN command so that user can
5051 select which HMAC is used to compute the MACs of the channel
5054 * Added Hmac field to the Channel Message Payload. The integrity
5055 of plaintext channel messages are now protected by computing
5056 MAC of the message and attaching the MAC to the payload. The
5057 MAC is encrypted. Now, it is clear that this causes some
5058 overhead to the size of the packet but rationale for this is that
5059 now the receiver can verify whether the channel message decrypted
5060 correctly and also when private keys are set for the channel the
5061 receiver can decrypt the packet with several keys and check from
5062 the MAC which key decrypted the message correctly.
5064 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5065 lib/silccrypt/silccipher.[ch].
5067 * Added silc_hash_len to return the digest length into the
5068 lib/silcrypt/silchash.[ch].
5070 * Rewrote parts of Silc Channel Payload interface in the
5071 lib/silccore/silcchannel.[ch]. The encode function now also
5072 encrypts the packet and parse function decrypts it.
5074 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5076 * Fixed a minor formatting bug in the SKE's key material processing.
5077 It actually might have processed the keys wrong way resulting
5080 * Redefined the mandatory HMAC algorithms and added new algorithms.
5081 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5082 and hmac-md5 truncated to 96 bits. The mandatory is now
5083 hmac-sha1-96. Rest are optional (including the one that used
5084 to be mandatory). Rationale for this is that the truncated HMAC
5085 length is sufficient from security point of view and can actually
5086 make the attack against the HMAC harder. Also, the truncated
5087 HMAC causes less overhead to the packets. See the RFC2104 for
5090 * Added new [hmac] configuration section. The SKE used to use
5091 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5092 is of course wrong. The official names that must be proposed in
5093 the SKE are the ones defined in the protocol specification
5094 (hmac-sha1-96 for example). The user can configure any hmac
5095 using any hash function configured in the [hash] section. At
5096 least, the mandatory must be configured.
5098 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5100 * Added HMAC list to the SKE proposal list. It has now both
5101 hash algorithm list and HMAC list. This makes the protocol
5102 incompatible with previous versions. The SKE now seems to work
5103 the way it is supposed to work, for the first time actually.
5105 * Defined plain Hash algorithms to the protocol specification.
5108 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5110 * Implemented support for key agreement packets into the server.
5111 Added functions silc_server_key_agreement and
5112 silc_server_send_key_agreement. Other than these functions,
5113 server has nothing to do with this packet.
5115 * Added support for private message key packets into the server.
5116 Added functions silc_server_private_message_key and
5117 silc_server_send_private_message_key.
5121 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5122 called in the protocol's final callback instead in the END
5123 protocol state. This makes a little more sense and in the same
5124 time in client we can use the same protocol routines for normal
5125 key exchange and to key agreement packet handling as well.
5127 * Added to both client's and server's KE protocol context the
5128 SilcSKEKeyMaterial pointer to save the key material. We will
5129 bring the key material to the protocol's final callback by doing
5130 this. The final callback must free the key material.
5132 * Added SKE's packet_send callback into client's KE protocol
5133 context so that the caller can choose what packet sending function
5134 is used. This way we can use different packet sending when
5135 doing normal SKE when doing key agreement packet handling (in
5136 the key agreement packet handling we do not want to encrypt
5139 * Implemented the responder side of the key agreement routines
5140 in the client. The client can now bind to specified port and
5141 accept incoming key negotiation. The key material is passed
5142 to the application after the protocol is over.
5144 * Implemented the processing of incoming Key Agreement packet
5145 in the client. Added function silc_client_key_agreement to
5148 * Implemented the intiator side of the key agreement routines
5149 in the client. The client can now initiate key agreement with
5150 another remote client. The key material is passed to the
5151 application after the protocol is over.
5153 * Created client_keyagr.c to include all the key agreement
5156 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5157 SILC_TASK_CALLBACK except that it is not static.
5159 * Created client_notify.c and moved the Notify packet handling
5160 from the client.[ch] into that file.
5162 * Created client_prvmsg.c and moved all private message and
5163 private message key routines from the client.[ch] into that file.
5165 * Create client_channel.c and moved all channel message and
5166 channel private key routines from the client.[ch] into that file.
5168 * Changed silc_client_get_client_by_id_resolve to resolve with
5169 WHOIS command instead of IDENTIFY command, in the file
5170 lib/silclient/idlist.c.
5172 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5174 * Implemented the SKE's responder side to the Client library.
5176 * When FAILURE is received to the protocol do not trust it
5177 blindly. Register a timeout to wait whether the remote closes
5178 the connection as it should do it, only after that process the
5179 actual failure. This was changed to both client and server.
5181 * Added client_internal.h to include some of the structures
5182 there instead of client.h in lib/silcclient/.
5184 * Added function silc_task_unregister_by_callback to unregister
5185 timeouts by the callback function.
5187 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Some "Incomplete WHOIS info" errors has been appearing on the
5190 log files. Took away the entry->userinfo check from WHOIS
5191 reply sending. The entry->userinfo is now " " if client did not
5192 provide one. I thought this was fixed earlier but something
5193 is wrong still. Let's see if the error still appears.
5195 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5197 * Fixed a minor bug in the login when the channel key is
5198 re-generated in the server. It used to generate the key in
5199 wrong order and thus caused problems in the channel traffic.
5201 * Fixed a minor bug in channel key distsribution after
5202 KICK command. The key was not sent to the router even though
5205 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Added silc_ske_process_key_material_data as generic routine
5208 to process any key material as the SILC protocol dictates. The
5209 function is used by the actual SKE library but can be used by
5210 applications as well. This relates to the private message keys
5211 and the channel private keys since they must be processed the
5212 same way the normal SILC session keys. The protocol dictates
5213 this. Affected files: lib/silcske/silcske.[ch].
5215 Added also silc_ske_free_key_material to free the
5216 SilcSKEKeyMaterial structure.
5218 * Defined silc_cipher_set_key function to set the key for
5219 cipher without using the object's method function. The affected
5220 files: lib/silccrypt/silccipher.[ch].
5222 * Implemented silc silc_client_add_private_message_key,
5223 silc_client_add_private_message_key_ske,
5224 silc_client_del_private_message_key,
5225 silc_client_list_private_message_keys and
5226 silc_client_free_private_message_keys functions in the
5229 Added functions silc_client_send_private_message_key to send
5230 the Private Message Key payload and silc_client_private_message_key
5231 to handle incoming Private Message Key payload.
5233 * Added Cipher field to the Private Message Key payload to set
5234 the cipher to be used. If ignored, the default cipher defined
5235 in the SILC protocol (aes-256-cbc) is used.
5237 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5239 * Removed lib/silcclient/ops.h file.
5241 Redefined parts of the SILC Client Library API. Created new
5242 file silcapi.h that deprecates the ops.h file and defines the
5243 published Client Library API. Defined also private message key
5244 API and channel private key API into the file.
5246 This is the file that the application must include from the
5247 SILC Client Library. Other files need not be included by
5248 the application anymore.
5250 * Added new key_agreement client operation callback and also
5251 defined the Key Agreement library API for the application.
5253 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5255 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5256 is used by clients to request key negotiation between another
5257 client in the SILC network. If the negotiation is started it
5258 is performed using the SKE protocol. The result of the
5259 negotiation, the secret key material, can be used for example
5260 as private message key.
5262 Implemented the Key Agreement payload into the files
5263 lib/silccore/silauth.[ch].
5265 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5267 * Redefined ciphers for the SILC protocol. Added some new ciphers
5268 and defined the key lengths for the algorithms. Changed the
5269 code accordingly. The default key length is now 256 bits.
5271 * Fixed SKE key distribution function silc_ske_process_key_material
5272 when the key length is more than 128 bits. The default key
5273 length in SILC is now 256 bits.
5275 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5276 to indicate unsupported algorithm.
5278 * Renamed rijndael.c to aes.c and all functions as well.
5280 * Fixed a long standing channel key setting bug in client library.
5281 Weird that it has never surfaced before.
5283 * Fixed bug in channel deletion. If the entire channel is removed
5284 then it must also delete the references of the channel entry
5285 from the client's channel list as the client's channel entry and
5286 the channel's client entry share same memory.
5288 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5290 * Implemented CONNECT and SHUTDOWN commands in the client.
5292 * Implemented CLOSE command to the client.
5294 * Added the function silc_idlist_find_server_by_name into the
5295 files silcd/idlist.[ch].
5297 Added the function silc_idlist_find_server_by_conn into the
5298 files silcd/idlist.[ch].
5300 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * DIE command was renamed to SHUTDOWN. Updated the both code
5305 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5306 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5308 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5311 * Added function silc_server_create_connection function to create
5312 connection to remote router. My server implementation actually
5313 does not allow router to connect to normal server (it expects
5314 that normal server always initiates the connection to the router)
5315 so the CONNECT command is only good for connecting to another
5318 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5320 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5321 or some other client was kicked from the channel.
5323 Implemented the handling of the notify type to both client
5326 Implemented silc_server_send_notify_kicked to send the KICKED
5327 notify. It is used to send it to the server's primary router.
5329 * Implemented the KICK command into server and client.
5331 * Added `query' argument to the silc_idlist_get_client function
5332 to indicate whether to query the client from server or not if
5335 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5336 to indicate that the client is not channel founder.
5340 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5342 * Removed the rng context from SilcPacketContext structure and
5343 changed that the packet routine uses the Global RNG API.
5345 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5347 * Added support for quit message that client can "leave" on the
5348 channel when it quits the SILC. It is ditributed inside the
5349 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5351 Added silc_server_free_client_data that will take the
5352 signoff message as argument.
5354 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5356 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5358 * Updated parts of the protocol specification to keep it up
5361 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5363 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5364 payloads in one packet.
5366 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5367 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5368 use now the new List flag.
5370 * Also deprecated the following packet types: REPLACE_ID,
5371 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5373 * Added list support for Notify packet in server.
5375 * Added silc_server_send_notify_channel_change to send the
5376 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5377 the silc_server_send_replace_id.
5379 * Added silc_server_send_notify_nick_change to send the
5380 NICK_CHANGE notify type. Deprecates the function
5381 silc_server_send_replace_id.
5383 * Added silc_server_send_notify_join to send the JOIN notify type.
5384 Deprecates the function silc_server_send_new_channel_user.
5386 * Added silc_server_send_notify_leave to send LEAVE notify type.
5387 Deprecates the function silc_server_send_remove_channel_user.
5389 * Added silc_server_send_notify_cmode and
5390 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5391 types. Deprecates the silc_server_send_set_mode function.
5393 * Added SERVER_SIGNOFF notify type to indicate that server has
5394 quit. This means that all clients on the channel from that
5395 server will drop. This can be also used when netsplit happens.
5397 Deprecated REMOVE_ID packet type since it is not needed anymore
5400 Added silc_server_send_notify_server_signoff to send the
5401 SERVER_SIGNOFF notify type. Deprecates the function
5402 silc_server_send_remove_id.
5404 Added also silc_server_send_notify_signoff to send the
5405 SIGNOFF notify type.
5407 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5408 SILC protocol from this day on. Changed the protocol
5409 specification as well.
5411 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5412 notify type. It is used between routers to notify about
5413 topic changes on a channel.
5415 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5418 * Partly updated the protocol specification to comply with the
5419 changes now made. It is still though a bit outdated.
5421 * The JOIN notify type now takes one extra argument <Channel ID>.
5422 The packet used to be destined to the channel but now the
5423 JOIN type may be sent as list thus it is impossible to
5424 destine it to any specific channel. By adding this argument
5425 it is again possible.
5427 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5429 * Added CREDITS file. The CHANGES and CREDITS file will appear
5430 in the distribution as well.
5432 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5434 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5435 types in the server's silcd/packet_receive.c.
5437 * Implemented CMODE and CUMODE to work in router environment.
5439 * Fixed minor encoding and decoding buglet from the
5440 lib/silccore/silcmode.c.
5442 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5445 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5447 * Changed all SilcConfigServer* and silc_config_server* to
5448 SilcServerConfig* and silc_server_config*, respectively.
5451 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5453 * Associated the ID (client or server ID) to the Authentication
5454 Payload to avoid any possibility of forging. Updated the
5455 protocol specification and the code accordingly.
5457 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5459 * The RSA key length is now save to the RsaKey context in the
5460 key generation process in lib/silccrypt/rsa.c. The key length
5461 is now used to figure out the maximum size of the block allowed
5462 to be encrypted/signed.
5464 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5465 is equivalent to the silc_mp_mp2bin but does not allocate any
5468 * Changed silc_mp_mp2bin API to take length argument. If it is
5469 non-zero then the buffer is allocated that large. If zero, then
5470 the size is approximated using silc_mp_sizeinbase, which however
5473 * Created Global RNG API which is global RNG that application can
5474 initialize. After initializing, any routine anywhere in the
5475 code (including library) can use RNG without allocating a new
5476 RNG object. This was done to allow this sort of use of the
5477 RNG in code that has no chance to allocate RNG object. All
5478 applications currently allocate this and many routines in the
5479 library use this. Affected file lib/silccrypt/silcrng.[ch].
5481 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5482 it to use the Global RNG API.
5484 * Defined Authentication Payload into protocol specification that
5485 is used during SILC session to authenticate entities. It is
5486 used for example by client to authenticate itself to the server
5487 to obtain server operator privileges.
5489 Implemented this payload into the lib/silccore/silcauth.[ch].
5490 Implemented also routines for public key based authentication
5491 as the new protocol specification dictates.
5493 Moved definitions of different authentication methods from
5494 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5496 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5497 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5498 silc_pkcs_verify_with_hash functions into the file
5499 lib/silccrypt/silcpkcs.[ch].
5501 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5503 * The client entry's userinfo pointer must be always valid.
5504 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5505 will fail since it requires the userinfo. Now, the userinfo
5506 is allocated as "" if actual userinfo does not exist. Actually,
5507 it must exist and it is totally Ok to drop client connections
5508 that does not announce the userinfo. However, we will make
5509 this workaround for now.
5511 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5512 to return the remote port by socket.
5514 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5516 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5517 SILC_SERVER_PENDING_EXEC and added an new macro
5518 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5519 data or when error occurs while processing the pending command.
5521 Added new argument `destructor' into silc_server_command_pending
5522 and to the SilcServerCommandPending object. This destructor is
5523 now called after calling the pending callback or if error occurs
5524 immediately. If error occurs the actual pending callback won't
5525 be called at all - only the destructor. The destructor may be
5526 NULL if destructor is not needed.
5528 All this applies for client library code as well. Similar
5529 changes were made there as well for the pending commands.
5531 In the client, the application must now allocate the
5532 SilcClientCommandContext with the silc_client_command_alloc
5535 * Added reference counter to the SilcServerCommandContext. Added
5536 function silc_server_command_alloc and silc_server_command_dup
5539 Same type of functions added to the client library for the same
5542 * Removed the cmd_ident from IDListData away since it is now
5543 global for all connections. It is the command identifier used
5544 in command sending and with pending commands. The affected file
5547 * Added reference counter to the SilcSocketConnection objecet to
5548 indicate the usage count of the object. The object won't be
5549 freed untill the reference counter hits zero. Currently only
5550 server uses this, and client ignores it. The client must be
5551 set to use this too later. The affected files are
5552 lib/silccore/silcsockconn.[ch]. Added also the function
5553 silc_socket_dup to increase the reference counter.
5555 This was mainly added because it is possible that the socket
5556 is removed underneath of pending command or other async
5557 operation. Now it won't be free'd and proper DISCONNECTING
5558 flags, etc. can be set to avoid sending data to connection that
5559 is not valid anymore.
5561 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5562 the connection. After that it sets SILC_SET_DISCONNECTED.
5563 It is, however, possible that the socket data is not still freed.
5564 The silc_server_packet_process now checks that data is not
5565 read or written to connection that is DISCONNECTED. The socket
5566 get's freed when the reference counter hits zero.
5568 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5570 * Changed the client operation API: channel_message operation's
5571 `sender' is now the client entry of the sender, not the nickname
5572 and the `channel' is the channel entry, not the channel name.
5574 In the private_message operation the `sender' is now also the
5575 client entry of the sender not the nickname.
5577 Affected file is lib/silcclient/ops.h and all applications
5578 using the client operations.
5580 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5582 * Moved the calling of ops->connect() from connect_to_server_final
5583 into receive_new_id functin since that is the point when the
5584 client is actually allowed to send traffic to network. The
5585 affected file is lib/silcclient/client.c.
5587 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5589 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5590 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5591 (if needs broadcasting) instead of broadcasting the packets one
5592 by one which would make a burst in the network traffic.
5594 * Added `broadcast' argument to the functions in silcd/server.[ch]
5595 silc_server_create_new_channel[_with_id] to indicate whether
5596 to send New Channel packet to primary router.
5598 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5600 * Added new function into the silcd/server.[ch] files:
5601 silc_server_create_new_channel_with_id to create new channel with
5602 already existing Channel ID.
5604 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5605 lib/silccore/silcpacket.h. This packet is used t send list of
5606 Set Mode payloads inside one packet. Server uses this to set
5607 the modes for the channels and clients on those channels, that it
5608 announced to the router when it connected to it. The protocol
5609 specification has been updated accordingly.
5611 * The silc_server_new_channel did not handle the packet coming
5612 from normal server as it normally does not send that. However,
5613 when it announces its channels it does send it. Implemented
5614 the support for that.
5616 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5617 into the file lib/silccore/id.h.
5619 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5621 * Fixed memory leaks in the functions silc_idlist_del_client,
5622 silc_idlist_del_channel and silc_idlist_del_server in the file
5623 silcd/idlist.c. All of those leaked like a sieve.
5625 * Fixed some small memory leaks in the client's function
5626 silc_client_notify_by_server.
5628 * Added functions into silcd/server.c: silc_server_announce_clients,
5629 silc_server_announce_channels and silc_server_announce_server.
5630 These functions are used by normal and router server to announce
5631 to its primary router about clients, channels and servers (when
5632 router) that we own. This is done after we've connected to the
5635 These functions effectively implements the following packet types:
5636 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5637 and SILC_PACKET_NEW_ID_LIST.
5639 * Added new functions into the silcd/packet_receive.[ch]:
5640 silc_server_new_id_list, silc_server_new_channel_list and
5641 silc_server_new_channel_user_list to handle the incoming
5642 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5644 * Added support of changing Channel ID in the function
5645 silc_server_replace_id. If the server that announces a channel
5646 to the router already exists in the router (with same name but
5647 with different Channel ID), router is responsible to send
5648 Replace ID packet to the server and force the server to change
5649 the Channel ID to the one router has.
5651 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5652 client that the Channel ID has been changed by the router. The
5653 normal server sends this to the client. Client must start using
5654 the new Channel ID as the channel's ID.
5656 Implemented handling of this new type into lib/silcclient/client.c
5657 into the function silc_client_notify_by_server.
5659 * Added new function silc_idlist_replace_channel_id into the files
5660 silcd/idlist.[ch] to replace the Channel ID.
5662 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5664 * Call silc_server_command_identify_check always when processing
5665 the IDENTIFY command in silcd/command.c
5667 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5669 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5670 send keepalive packets. The packet can be sent by clients,
5671 servers and routers.
5673 Added function silc_socket_set_heartbeat into the file
5674 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5675 If not set, the heartbeat is not performed. The actual
5676 heartbeat is implemented in the low level socket connection
5677 library. However, application is responsible of actually
5680 Added silc_server_send_heartbeat to send the actual heartbeat
5681 packet into silcd/packet_send.[ch]. Server now performs
5682 keepalive with all connections.
5684 * Added silc_task_get_first function into lib/silcutil/silctask.c
5685 to return the timeout task with shortest timeout. There was a bug
5686 in task unregistration that caused problems. TODO has been
5687 updated to include that task system must be rewritten.
5689 * The client library will now resolve the client information when
5690 receiving JOIN notify from server for client that we know but
5691 have incomplete information.
5693 * Rewrote parts of silc_server_remove_from_channels and
5694 silc_server_remove_from_one_channel as they did not remove the
5695 channel in some circumstances even though they should've.
5697 * Encryption problem encountered in server:
5699 The LEAVE command used to send the Channel Key packet to the
5700 router immediately after generating it. However, the code
5701 had earlier sent Remove Channel user packet but not immediately,
5702 ie. it was put to queue. The order of packets in the router
5703 was that Channel Key packet was first and Remove Channel User
5704 packet was second, even though they were encrypted in the
5705 reverse order. For this reason, MAC check failed. Now, this
5706 is fixed by not sending the Channel Key packet immediately but
5707 putting it to queue. However, this is more fundamental problem:
5708 packets that are in queue should actually not be encrypted
5709 because packets that are sent immediately gets encrypted
5710 actually with wrong IV (and thus MAC check fails). So, packets
5711 that are in queue should be encrypted when they are sent to
5712 the wire and not when they put to the queue.
5714 However, the problem is that the current system has not been
5715 designed to work that way. Instead, the packet is encrypted
5716 as soon as possible and left to the queue. The queue is then
5717 just purged into wire. There won't be any fixes for this
5718 any time soon. So, the current semantic for packet sending
5721 o If you send packet to remote host and do not force the send
5722 (the packet will be in queue) then all subsequent packets to the
5723 same remote host must also be put to the queue. Only after the
5724 queue has been purged is it safe again to force the packet
5727 o If you send all packets immediately then it safe to send
5728 any of subsequent packets through the queue, however, after
5729 the first packet is put to queue then any subsequent packets
5730 must also be put to the queue.
5732 Follow these rules and everything works fine.
5734 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5736 * Added new function silc_server_remove_clients_by_server to
5737 remove all client entries from ID list when the server connection
5738 is lost. In this case it is also important to invalidate all
5739 client entires as they hold the invalid server entry. This
5740 fixes fatal bug when server has lost connection and will reconnect
5743 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5745 * Made some sanity checks to silc_server_daemonise like to check
5746 whether the requested user and group actually exists.
5748 * Added sanity check to SKE's silc_ske_responder_finish to check
5749 that the public and private key actually is valid.
5751 * Invalidate the client's nickname when receiving Replace ID
5752 packet and the Client ID is being replaced. This means that the
5753 server will query the nickname if someone needs it (client)
5756 * Sort the ID Cache in client library when the ID Cache data
5757 has changed (needs sorting).
5759 * Do not allow for SILC client to create several connections to
5760 several servers. The client does not support windows right now
5761 and generating multiple connections causes weird behaviour.
5763 Irssi-silc client does support windows and can handle several
5764 connections without problems, see: www.irssi.org and SILC plugin.
5766 * Fixed some places where client was added to the IDList. The
5767 rule of thumb is following (in order to get everything right):
5768 If the client is directly connected local client then the
5769 `connection' argument must be set and `router' argument must be
5770 NULL to silc_idlist_add_client function. If the client is not
5771 directly connected client then the `router' argument must
5772 bet set and the `connection' argument must be NULL to the
5773 silc_idlist_add_client function.
5775 * The funtion silc_server_packet_send_local_channel actually did
5776 not check whether the client was locally connected or not. It
5777 does that now. Fixed a bug related to LEAVE command.
5779 * Fixed Remove Channel User payload parsing bug in server's
5780 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5782 * The server's silc_server_save_channel_key now checks also the
5783 global ID list for the channel as it might not be in the local
5784 list. Fixed a bug related to LEAVE command.
5786 * Is this the end of the [<unknown>] buglet that has been lurking
5787 around for a long time? A little for loop fix in server's
5788 silc_server_command_whois_parse that is used by both IDENTIFY
5789 and WHOIS command. At least, this was a clear bug and a cause
5790 of one type of [<unknown>] buglet.
5792 * WHOIS and IDENTIFY commands call the function
5793 silc_server_command_[whois/identify]_check function even if
5794 we are not router server.
5796 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5798 * Added --with-gmp configuration option. If set the GMP
5799 is always compiled in the SILC source tree. If not set then
5800 it is checked whether the system has the GMP3 installed. If
5801 it has then the GMP won't be compiled (the system's headers
5802 and library is used), if it doesn't have it then the GMP is
5803 compiled in the SILC source tree.
5805 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5807 * Changed RSA private exponent generation to what PKCS #1
5808 suggests. We try to find the smallest possible d by doing
5809 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5810 not security fix but optimization.
5812 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5814 * Added new config entry [Identity] to fork the server and run
5815 it as specific user and group. A patch from Bostik.
5817 * Imported Dotconf configuration library into lib/dotconf.
5818 This will be used to create the SILC configuration files later.
5819 It will appear in the distsribution after this commit.
5821 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5823 * A big code auditing weekend happening. Auditing code for
5824 obvious mistakes, bugs and errors. Also, removing any code
5827 Removed files for being obsolete:
5829 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5830 inline in the file lib/silcutil/silcbuffer.h)
5832 o lib/silcutil/silcbufutil.c (the header has inline versions)
5834 Changed code to fix possible error conditions:
5836 o The buffer formatting routines now check that the destination
5837 buffer really has enough space to add the data. This applies for
5838 both buffer formatting and unformatting
5839 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5840 unformatting was changed to accomodate following rules:
5841 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5842 sent to the function while XXX_*STRING will not allocate or copy
5843 the data into the buffer. Instead it sets the pointer from the
5844 buffer into the pointer sent as argument (XXX_*STRING used to
5845 require that the pointer must be allocated already). This change
5846 makes this whole thing a bit more consistent and more optimized
5847 (note that the data returned in the unformatting with XXX_*STRING
5848 must not be freed now). The routines return now -1 on error.
5850 o Tried to find all code that use buffer_format and buffer_unformat
5851 and added return value checking to prevent formatting and
5852 especially unformatting errors and possible subsequent fatal
5855 o Changed ske->x and ske->KEY to mallocated pointers in
5856 lib/silcske/silcske.h. Fixed possible data and memory leak.
5858 o Added return value checking to all *_parse* functions. Fixed
5859 many memory leaks as well.
5861 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5862 so that buffer overflows would not happen. All code now also
5863 checks the return value as it can fail.
5865 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5867 * Added reconnection support to server if the normal server looses
5868 its connection to the router (for example if router is rebooted).
5869 The server performs normal reconnection strategy implemented
5870 to the server. Affected file silcd/server.c.
5872 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5874 * Added new packet type SILC_PACKET_SET_MODE that is used to
5875 distribute the information about changed modes (for clients,
5876 channels and clients channel modes) to all routers in the
5877 network. Updated the protocol specification accordingly.
5879 Added functions into silcd/packet_send.c and
5880 silcd/packet_receive.c: silc_server_send_set_mode,
5881 silc_server_set_mode.
5883 Added new files silcmode.[ch] into lib/silccore that implements
5884 the encoding and decoding of Set Mode Payload. Added new type
5885 SilcSetModePayload. Moved the definitions of different modes
5886 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5888 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5890 * Oops, a little mistake in server's connection authentication
5891 protocol. The protocol is not ended with FAILURE but with
5892 SUCCESS if the authentication is Ok. :) Affected file is
5895 * Implemented NICK_CHANGE notify handling in server in the file
5896 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5897 the local clients on the channel. After the changing nickname
5898 in router environment snhould work and the [<unknown>] nickname
5899 should appear no more.
5901 The silc_server_replace_id function that receives the Replace ID
5902 payload now sends the NICK_CHANGE notify type also in the file
5903 silcd/packet_receive.c
5905 * Changed WHOIS and IDENTIFY command to support the maximum amount
5906 of arguments defined in protocol specs (3328 arguments). This
5907 fixed a bug that caused problems when there were more than three
5910 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5912 * Added extra parameter, command identifier, to the
5913 silc_client_send_command so that explicit command identifier
5916 Changed that ID list routines uses specific command identifier
5917 when sending WHOIS/IDENTIFY requests to the server so that they
5918 can be identified when the reply comes back.
5920 Affected files lib/silcclient/command.[ch],
5921 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5923 * Added `sender' argument to silc_server_packet_send_to_channel
5924 to indicaet the sender who originally sent the packet to us
5925 that we are now re-sending. Ignored if NULL. Affected file
5926 silcd/packet_send.[ch].
5928 * Added some server statistics support in silcd/server_internal.h
5929 SilcServerStatistics structure and around the server code. Also
5930 send some nice statistics information when client is connecting
5933 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5935 * Fixed channel ID decoding in server's JOIN command reply in
5936 silcd/command_reply.c
5938 * Fixed braodcasting of replace ID payload to not to send it if
5939 we are standalone server in silcd/packet_receive.c.
5941 * Fixed all channel message sending routines to not to send
5942 packets to clients that has router set, since they are routed
5943 separately in the same function earlier. Affects file
5944 silcd/packet_send.c and all channel packet sending functions.
5946 * In USERS reply, res_argv[i] are not allocated, the table
5947 is allocated. Thus changed that free the table, not its
5950 * In server's whois_check and identify_check if the client is
5951 locally connected do not send any WHOIS commands - they are not
5954 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5956 * Fixed some minor bugs in client when sending WHOIS command. The
5957 arguments was in wrong order.
5959 * Removed statis function add_to_channel from server in
5960 silcd/command.c that was previously used with the joining but
5963 * Tested USERS command in router environment successfully with two
5964 routers, two servers and two clients.
5966 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5968 * Reorganized the USERS command and command reply in client library
5969 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5970 When the command is given by user we register a pending command
5971 callback that will reprocess the command after the reply has been
5972 received from the server. When reprocessing the packet we then
5973 display the information. Thus, the USERS information is displayed
5974 now in the command callback instead of in the command reply
5975 callback. The processing of the command is same as previously
5976 when server has sent the command reply in the JOINing process.
5978 * Added to USERS command in silcd/command_reply.c to join the client,
5979 we didn't use to know about, to the channel after we've created
5980 a client entry for it. Also, for clienet we did know already still
5981 check whether it is on the channel or not and add it if not.
5983 * Removed silc_server_command_join_notify as the function and its
5986 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5988 * Changed the client's pending command handling to the same as the
5989 server's pending command handling. It is also now possible to
5990 execute command reply functions from other command reply
5991 function as the function callbacks for commands and command
5992 replies are one and same. The pending commands are not static
5993 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5994 in client connection context. Thus, pending commands are server
5995 connection specific as it is convenient.
5997 Changed the function silc_client_command_pending and
5998 silc_client_command_pending_del and added new function
5999 silc_client_command_pending_check. Removed the
6000 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6003 * Added cmd_ident, current command identifier, to the client
6004 connection context in lib/silcclient/client.h to keep track on
6005 command identifiers used in command sending. Client's command reply
6006 function handling now supports the mandatory command identifiers.
6008 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6009 funtions in client to fully support pending command callbacks.
6011 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6012 as one of the arguments to the application in the command reply
6015 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6016 before first releasing SILC but came back. Now it is removed again
6017 and should come back nomore. The FORWARDED flag was used only
6018 by the JOINing procedure by forwarding the command packet to router.
6019 Now, the JOINing procedure has been changed to more generic (due
6020 to various router environment issues) and FORWARDED is not needed
6021 anymore for anything. The protocol specification is yet to be
6024 Now, removed silc_server_packet_forward from server and the flag
6025 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6027 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6029 * Renamed NAMES command to USERS command. The NAMES was named that
6030 due to historical reasons. Now it is renamed. Also, rewrote
6031 parts of the USERS command. The nickname list is not sent anymore
6032 by the server. Only Client ID and mode lists are sent in the USERS
6033 command. Changed this also to the protocol specification.
6035 The client now resolves the names and stuff after it receives
6036 the USERS list from the server when joining to the channel.
6038 * WHOIS and IDENTIFY commands has been changed to support multiple
6039 Client ID's per command. One can now search for multiple users
6040 in the network by sending only one WHOIS or IDENTIFY command.
6041 Changed the code and the protocol specifications.
6043 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6044 uses silc_server_command_whois_parse to parse the request. */
6046 * If normal server, do not parse the WHOIS and IDENTIFY requests
6047 before sending it to the router. Saves some time.
6049 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6051 * Fixed JOIN command on client library. Wrong number of arguments
6052 used to crash the client.
6054 * Added silc_server_channel_has_global function to check whether
6055 channel has global users or not.
6057 * Added silc_server_channel_has_local function to check whether channel
6058 has locally connected clients on the channel.
6060 * The silc_server_remove_from_one_channel now checks whether the
6061 channel has global users or not after given client was removed from
6062 the channel. It also checks whether the channel has local clients
6063 on the channel anymore. If it does not have then the channel entry
6064 is removed as it is not needed anymore.
6066 * The silc_server_notify now checks on JOIN notify whether the joining
6067 client is one of locally connected or global. If it is global then
6068 the channel has now global users on the channel and that is marked
6069 to the channel entry. Also, it now saves the global client to
6070 global list who is joining and JOINs it to the channel. This is
6071 for normal server, that is.
6073 Changed silc_server_send_notify_on_channel,
6074 silc_server_packet_relay_to_channel and
6075 silc_server_packet_send_to_channel check if we are normal server
6076 and client has router set (ie. global client) do not send the
6077 message to that client, as it is already routed to our router.
6079 * Implemented LEAVE notify type handling in silc_server_notify
6082 * Tested LEAVE command in router environment successfully. Tested
6083 with two routers, two servers and two clients.
6087 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6089 * Implemented SIGNOFF notify type handling in silc_server_notify
6092 * silc_server_remove_id now removes the client entry from all channels
6093 it has joined and thusly sends SIGNOFF notify type.
6095 * Rewrote the NAMES list generation in server by removing two excess
6096 loops. The lists are created now inside one loop.
6098 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6100 * silc_server_remove_channel_user checks now also global list
6101 for channel and client.
6103 * silc_server_new_channel_user checks now both local and global
6104 list for channel and client. Fixed a bug in client id decoding.
6105 Used to decode wrong buffer.
6107 * silc_server_channel_message checks now both local and global
6108 list for channel entry.
6110 * Tested channel joining (hence JOIN) in router environment
6111 successfully. Tested with two routers, two servers and two
6114 * Tested channel message sending in router environment successfully.
6116 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6118 * Added silc_server_save_channel_key into server.[ch] to save the
6119 received channel key in Channel Key payload processing. It is
6120 also used in JOIN command reply handling.
6122 Equivalent function silc_client_save_channel_key added into
6123 client.[ch] into client library.
6125 * Changed JOIN command reply to send information whether the channel
6126 was created or not (is existing already) and the channel key
6127 payload. Changed protocol specs accordingly.
6129 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6130 the request was sent by ID and not by nickname. Crashed on
6133 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6135 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6136 now correctly save the received data.
6138 * silc_server_free_sock_user_data now notifies routers in the
6139 network about entities leaving the network.
6141 At the same time implemented functions silc_server_remove_id
6142 and silc_server_send_remove_id to receive and send REMOVE_ID
6143 packets. The packet is used to notify routers in the network
6144 about leaving entities. The ID removed will become invalid in
6147 * Added function silc_idlist_del_server into server. Removes and
6148 free's server entry from ID list.
6150 * silc_server_private_message function now checks, if we are router,
6151 that the destination ID really is valid ID, naturally.
6153 * In router when NEW_ID packet is received (for new client) the
6154 hash of the Client ID is saved in the ID Cache but the
6155 client->nickname is set to NULL, instead of putting the hash
6158 IDENTIFY command now also checks that client->nickname must be
6159 valid. If it is not if will request the data from the server who
6160 owns the client. Added new function
6161 silc_server_command_identify_check.
6163 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6164 to set the command to already allocated Command Payload.
6166 * Tested private message sending in router environment with two
6167 routers, two servers and two clients. Fixed minor bugs and now
6170 * Fixed segfault from client's NAMES command. Used to crash if
6173 * Forwarded packets must not be routed even if it is not destined
6174 to the receiver. Changed server code comply with this.
6176 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6178 * Added `require_reverse_mapping' boolean value to ServerParams
6179 structure. If TRUE (not default) the server will require that
6180 the connecting host has fully qualified domain name.
6182 If the reverse mapping is not required and hostname could not be
6183 found the IP address is used as hostname.
6185 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6187 * Implemented version string checking to both client and server.
6188 The check is incomplete currently due to the abnormal version
6189 strings used in development version of SILC.
6191 * Changed all command functions in server to use the new
6194 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6196 * Changed char *data to unsigned char *data in ID Cache system to
6197 support binary data as ID Cache data. Changed code to support
6198 binary data in lib/silccore/idcache.c.
6200 * Renamed silc_server_packet_relay_command_reply to
6201 silc_server_command_reply as it is normal packet receiving
6202 function. Rewrote the function to accept command replys for
6203 servers and not only for clients.
6205 * Mark remote router always as registered server if we are connecting
6206 to it. Otherwise, commands sent by the router to us are ignored.
6208 * All ID List find routines now returns the ID Cache Entry pointer
6209 as well if requested.
6211 * WHOIS command works now in router environment, tested with two
6212 routers, two servers and two clients.
6214 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6215 in router environment (as it is almost equivalent to WHOIS) but
6216 hasn't been tested thoroughly. Added new functions:
6218 silc_server_command_identify_parse
6219 silc_server_command_identify_send_reply
6220 silc_server_command_identify_from_client
6221 silc_server_command_identify_from_server
6223 * Disabled route cache adding because adding two different ID's with
6224 same IP replaces the old cache entry thus giving wrong route.
6225 The entry->router->connection is always the fastest route anyway
6226 so route cache may not be needed. Of course, new routes maybe
6227 established after receiving the ID when the entry->router->connection
6228 might not be anymore the most optimal.
6230 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6232 * Add route cache for received ID for fast routing.
6234 * Added silc_server_packet_route to route received packet on router
6235 that is not destined to us.
6237 * Renamed silc_server_get_route to silc_server_route_get.
6239 * Added id_string and id_string_len fields into SilcServer to
6240 include encoded ServerID for fast comparing without excess
6241 encoding of the ID's.
6243 * Cleaned up WHOIS command on server side. Added following static
6246 silc_server_command_whois_parse
6247 silc_server_command_whois_check
6248 silc_server_command_whois_send_reply
6249 silc_server_command_whois_from_client
6250 silc_server_command_whois_from_server
6252 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6253 arguments in command replies. All command functions should be
6254 updated to use this macro.
6256 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6258 * Minor typo fixes on command reply handling on server.
6260 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6262 * Added silc_server_command_add_to_channel internal routine to add
6263 the client to the channel after router has created the channel and
6264 sent command reply to the server.
6266 * Added generic silc_server_send_command to send any command from
6269 * Use static buffer with ID rendering instead of duplicating data.
6271 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6273 * Fixed a channel user mode bug when joining to a channel server gave
6274 everybody channel founder rights, oops.
6276 * We mark ourselves as the router of the incoming server connection
6277 if we are router ourselves. This way we can check in some packet
6278 sending functions whether it is locally connected server. For
6279 incoming router connections we put NULL.
6281 * For router sending packets locally means now always sending the
6282 packet cell wide; to local clients and local servers. For normal
6283 server sending packet locally means sending it to only local
6286 * Fixed the JOIN command to really work in router environment. If the
6287 channel is created it is always created by the router. Router is
6288 also responsible of making the initial joining to the channel,
6289 sending JOIN notify to the sending server and distributing
6290 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6291 does not exist server doesn't do anything else but forward the
6292 command to the router which performs everything.
6294 * Added silc_server_send_channel_key function to send the Channel Key
6297 * Added silc_server_create_channel_key to create new channel key. The
6298 channel key is now re-generated everytime someone joins or leaves
6299 a channel, as protocol dictates. Note: channel->key_len is the
6302 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6304 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6305 packet_receive.[ch] to separate packet sending and receiving
6306 routines. The server.[ch] now includes everything else including
6307 actual packet processing (writing and reading data) and other
6310 Renamed silc_server_private_message_send_internal to
6311 silc_server_send_private_message. The routine is still though
6312 used only to relay private messages as server does not send
6313 private messages itself.
6315 Renamed silc_server_new_channel to silc_server_create_new_channel
6316 and added new function sicl_server_new_channel that handles the
6317 incoming New Channel packet. Added also new sending function
6318 silc_server_send_new_channel to send New Channel Payload.
6320 * Added new function silc_server_notify to process incoming notify
6321 packet to the server/router. Server may then relay the notify
6322 to clients if needed.
6324 * Added new function silc_server_new_channel_user to process incoming
6325 New Channel User packet. Router will redistribute the packet and
6326 send JOIN notify to its local clients and locally connected servers
6327 if needed. Normal server will send JOIN notify to its local client
6328 on same channel when received this packet. Added also corresponding
6329 sending function silc_server_send_new_channel_user to sent the
6332 * Added boolean route argument to send_notif_to_channel and
6333 packet_send_to_channel functions to attempt to route the packet
6334 if it is TRUE and send only locally if it is FALSE.
6336 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6338 * silc_server_replace_id now broadcasts the received replace ID
6339 packet if it is not broadcast packet already. The router must
6340 broadcast to inform other routers about changed ID.
6342 * Added backpointer to server's router into SilcServer context in
6343 silcd/server_internal.h.
6345 * Fixed silc_server_packet_broadcast to send correct broadcast
6348 * The channel key is now distributed to the local client as soon
6349 as it is received from the router (in router environment) so that
6350 no other packet may be sent for the channel until client has
6353 * silc_server_remove_channel_user now broadcasts the received
6354 Remove Channel User packet if it is not broadcast packet already.
6355 The router must broadcast to inform other routers about removed
6358 * Added users field into SilcPacketContext that is a reference count
6359 of the context. One can increase the reference count by calling
6360 silc_packet_context_dup which is now changed to just increase the
6361 reference count instead of duplicating the data. The reference
6362 count is decresed by calling silc_packet_context_free that will
6363 free the data after the reference count hits zero.
6365 For now on the packet context and everything allocated into it
6366 (including the raw packet from network) must be freed by calling
6367 the new silc_packet_context_free function. Added also new function
6368 silc_packet_context_alloc that must be used now to allocate the
6369 context. This also means that if a routine is asynchronous from
6370 silc_[client/server]_packet_parse_type the packet context must
6371 be duplicated by calling silc_packet_context_dup. Otherwise it
6372 gets free'd after silc_[client/server]_packet_parse_type returns.
6373 Also, one must remember that if packet is duplicated then its
6374 reference count must be decresed by calling the free function as
6375 many times as it was duplicated.
6377 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6378 from both client and server.
6380 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6382 * Made joining to a channel working in router environment.
6384 * Cleaned up JOIN command on server side and create function
6385 silc_server_command_join_channel internal routine to make the
6388 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6390 * Changed silc_command_pending list to SilcDList. Also, added
6391 `ident' field to SilcServerCommandPending structure to identify
6392 the reply and to call correct callback.
6394 Added silc_server_command_pending_check function to replace the
6395 corresnponding macro. The silc_command_pending list is not
6398 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6399 to set identifier to previously allocated Command Payload. It
6400 is used to set identifier for command when resending Command
6403 * Added silc_command_payload_encode_payload to encode Command
6404 Payload buffer from SilcCommandPayload structure.
6406 * Added silc_argument_payload_encode_payload to encode Argument
6407 payload buffer from SilcArgumentPayload structure.
6409 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6411 * Changed WHOIS command to support router connection on server side.
6412 The whois request is always sent to router unless the server is
6413 standalone server. After server has received the reply from the
6414 router will it send the reply to the client.
6416 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6417 broadcast received broadcast packet. The function is used only
6418 by router. The broadcast packet is always sent to the router's
6421 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6422 render given ID to printable string, for log files for example.
6424 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6426 * Made basic router to router connections working. At least they
6427 can now connect to each other but nothing really works the way
6428 they are supposed - yet.
6430 * Added new initiator token to RouterConnection configuration
6431 file in silcd/serverconfig.[ch]. It is used to tell whether we
6432 are the initiator to the remote router or whether we'll expect
6433 the other end to connect.
6435 * Moved registering of listener task to silc_server_init, hence
6436 the server starts listenning as soon as it is run, even if it
6437 does not have connections to other routers. Let's see how well
6440 * Changed default connection retry timeouts for more suitable in
6443 * Removed cipher and such arguments from silc_idlist_add_client
6444 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6445 Added new function silc_idlist_add_data to add the keys and stuff
6448 * Added SilcIDListData structure and added it to SilcClientEntry
6449 and SilcServerEntry as their first field in the structure. This
6450 way we can explicitly cast the ID entries to the SilcIDListData
6451 structure and get common data for the entries. In past, we had
6452 to first check what type of connection it is and then cast it to
6453 correct ID entry type. Now, we can directly cast the opaque
6454 pointer to the SilcIDListData (no matter what ID entry it actually
6455 is) and get the data needed.
6457 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6459 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6460 in some circumstances even if threre were timeout tasks, though not
6461 IO tasks, but tasks anyway. Now fixed.
6463 * Defined SilcServerConnection structure to hold connection specific
6464 stuff about directly connected servers and routers. The definition
6465 is currently in silcd/server_internal.h. I thought about having
6466 a bit more important role fro this struct but for now it is used
6467 only when connecting to other server (or router actually).
6469 * Added connecting retry support in server when connecting to
6470 router(s). The retry feature implement exponential backoff
6471 algorithm. Also, added SilcServerParams structure to hold default
6472 parameters for server. For now, it include these retry settings
6473 and are hard coded. After server is moded to be as Silc Server
6474 Library this structure will be more important.
6476 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6478 * Changed client librarys channel->clients table to SilcList and
6479 changed code accordingly.
6481 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6483 * Changed client's channel table to SilcList and changed code
6484 accordingly. Also changed SilcChannelClientEntry to include back-
6485 pointer to the channel so that client entry can use that structure
6486 as list as well and we have fast cross-reference to the channel.
6487 This change dramatically decreased the complexity of channel
6488 handling with client entry and vice versa (removed one extra
6489 loop when searching for channel entry from many functions).
6491 * Changed server->sim from table to SilcDList and changed code
6494 * NAMES command can now be used from user interface. It will show
6495 the user list on the channel, neatly.
6497 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6498 Code now saves realname of the user if it becomes available.
6500 * Renamed configure.in to configure.in.pre and made ./prepare
6501 script to automatically add correct version string to
6502 configure.in which it creates from configure.in.pre.
6504 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6506 * NAMES command reply now shows users mode with the nickname when
6509 * Moved silc_client_ch[u]mode[_char] functions from
6510 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6511 place sucks, they are utility functions and should be in some
6514 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6516 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6519 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6523 * Added TRQ (efficient deque and list library) into lib/trq. This is
6524 a very good list library that is currently used in the SILC. Defined
6525 SilcList API over the library because I didn't like the API very
6526 much. See lib/trq/silclist.h for the API and examples of how to
6527 use the API. Fixed various places in the code to use the new
6528 SilcList API. The SilcList is meant for lists that has a structure
6529 already defined as a list. It is not suitable to add just some
6530 context to the list (in TRQ, the context is the list actually).
6532 So, I defined SilcDList that can be used for the purpose where
6533 predefined list structure does not exit. This can be used as
6534 such list. Now some context just can be added to the SilcDList.
6535 Currently this list is not used in the SILC just yet, though there
6536 are a lot places where this can replace dynamically allocated
6537 tables and I will fix these places, later, to use SilcDList.
6538 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6539 and use TRQ internally).
6541 Also fixed some annoying warning messages that the original TRQ
6542 code generated. Also minor changes to TRQ's Makefile.in.
6544 * Added support for querying by Client ID to both WHOIS and
6545 IDENTIFY commands into server, as required by the protocol.
6547 * Removed method function pointers from SilcBuffer structure. They
6548 weren't used to anything and just increased the context size for
6549 no good reason. This change also made silc_buffer_alloc and
6550 silc_buffer_free functions inline functions.
6552 * Disabled command flooding detection support until it's fixed so
6553 that it accepts commands in but does not execute them more than once
6556 * Added silc_net_localhost(), to return local hostname, into
6557 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6558 that must be initialized before calling silc_client_init.
6560 * Added new function: silc_server_send_notify_on_channels to send
6561 notify messages to all channels client has joined. It is assured
6562 that the message is sent only once per client.
6564 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6565 lib/silcutil/silcutil.[ch] as silc_format function. The new
6566 function is generic and is used by server as well, not only by
6567 the logging routines.
6569 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6570 the provided version string was not acceptable. Added new function:
6571 silc_ske_check_version into lib/silcske/silcske.h. The function
6572 must be implemented by the application (client or server) and it
6573 does not reside in the SKE library. The function checks the version
6574 string remote end sent.
6576 * Added back pointers (to opaque context and to SilcSocketConnection)
6577 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6579 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6580 duplicate packet context structure.
6582 * Changed `notify' client operation to send same arguments as client
6583 receives from server except for ID's. ID's are mapped to correct
6584 ID entry and that is returned. Also, if channel entry is not sent
6585 by server but the notify is for channel the channel entry is sent
6586 to application (otherwise application doesn't know that it is for
6587 channel (library gets it from packet's Destination ID)).
6589 * Added silc_client_remove_from_channels into client library to
6590 remove a client from all channels it has joined to. Used when
6591 received SIGNOFF notify from server. Added also new function
6592 silc_client_replace_from_channels to replace old ID entry with
6593 new ID entry on all channels. Used when received NICK_CHANGE
6596 * Fixed ID Cache list handling in silc_idlist_get_client in
6597 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6598 to get (or query) client by ID.
6600 * Updated TODO list.
6602 * Added connection authentication status message defined by the
6603 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6604 support for these into the code in client and server side.
6606 * Added generic function silc_client_send_command to send any command
6607 with variable argument list. Application should use this function
6608 to send commands if the command functions provided by the library
6609 does not suite for the application's user interface needs.
6611 * Added new `failure' client operation. Application is notified about
6612 received failure packet if client is executing a protocol. In this
6613 case the protocol's execution has failed.
6615 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6616 is required by the protocol.
6618 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6619 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6622 * Added status flag to SilcSKE object to indicate realtime status
6623 of the SKE protocol.
6625 * Application receives now exactly same command reply arguments as
6626 the library receives from server. However, if ID is received the
6627 corresponding ID entry is returned to the application (eg. Client
6628 ID is mapped to correct SilcClientEntry entry and that is returned).
6629 Changed command_reply client operation due to this change.
6631 * Changed all ID's in commands and in command replys as ID Payloads.
6632 Change affected both client and server side codes.
6634 All ID's sent in SILC network (with execption of ID's in SILC
6635 Packet header) are sent in ID Payload to support variable length
6638 * Server now notifies nick changes and notifies all clients on
6639 the channels about the new nickname (about the new Client ID,
6642 * Implemented CMODE command to change channel modes. Supports all
6643 channel modes defined by the protocol specs except ban and invite
6644 lists. (Also, private channel key mode is supported but support for
6645 setting private channel key in client is missing, thus, this mode
6646 has no effect on client side (except that server requires that the
6647 client uses private channel key and normal channel traffic does not
6650 Also, invite mode works per se, but INVITE command does not work
6651 yet correctly, so you can set channel as invite only channel but
6652 inviting clients to the channel does not work (it is yet to be
6653 thought what's the best way to do it).
6655 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6656 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6657 Implemented CUMODE command to change user's mode on the channel.
6658 Supports all modes defined by the protocol specs.
6660 * Added NAMES command reply to return users modes on the channel.
6662 * Removed unnecessary and slow ciphers from lib/silccrypt.
6664 * Set SO_KEEPALIVE option to connection sockets by default.
6666 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6668 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6669 redefined the Notify Payload into protocol specs.
6671 * Added silc_id_payload_parse_id to get ID directly from raw
6674 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6676 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6677 accept searching by Client ID as well.
6679 * Added support for LEAVE and SIGNOFF notify types in client library.
6681 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6682 to parse ID Payload from raw data.
6684 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6686 * Added flags parameter into silc_ske_assemble_security_properties
6687 function in lib/silcske/silcske.[ch].
6689 * Changed notify client operation to fit better for notify messages
6690 sent by server. The notify payload received from server is now
6691 passed to the application (after parsing it to SilcNotifyPayload).
6692 It is application's responsibility to retrieve the arguments
6693 from the payload and show the message the way it wants. The message
6694 sent by server is implementation specific.
6696 * Changed public keys to comply with the protocol specification.
6697 Old public keys are not supported anymore and are not compatible.
6699 * Removed nickname from Channel Payload as the latest draft removed
6700 it. The client must resolve the nickname from the NAMES command
6701 reply received when it joined the channel.
6703 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6705 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6707 * Fixed some errors in protocol specification drafts.
6709 * Created lib/silccore/silcnotify.c to implement Notify Payload
6710 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6711 generic payloads described by protocol specifications. The file
6712 includes implementations for ID Payload and Argument Payload.
6714 * Changed Command Payload implementation to use the new Argument
6715 Payload. Changed command_xxxx_payload to command_payload_xxxx
6716 to comply with SILC coding conventions.
6718 * Added suppport for Argument Payload handling in Notify Payload
6719 implementation as protocol requires it. Added the new support
6720 into server and client lib as well.
6722 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6724 * Added support for multiple nicknames on same channel. [n] is
6725 added locally to the nickname if there are more than one same
6726 nicknames on the channel.
6728 * Server now sends all nicknames that matched WHOIS request.
6729 Client also shows the list received from server.
6731 * Added TOPIC command to client side. User can now set and show
6732 current topic on channel.
6734 * Added MOTD command to client and server. Also, server sends the
6735 motd when client connects to the server.
6737 * Changed version strings to comply ISO 8601.
6739 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6741 * Fixed protocol error handling in client library. It should now
6742 cope even if the SKE fails for some reason.
6744 * Made new protocol specification drafts for submitting to IETF.
6746 * Implemented TOPIC command to server in silcd/command.c.
6748 * Added two new notify types into lib/silccore/silcnotify.h:
6749 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6750 notify nickname change and topic setting/change on a channel.
6752 * API change of command_reply operation in client library. The
6753 application gets now the status type received from server as well.
6755 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6757 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6759 * Cras fixed and optimized the packet handling even further and
6760 it should work now. Minor change to the prototype of function
6761 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6763 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6765 * Added new function into lib/silcutil/silcschedule.[ch]:
6766 silc_schedule_with_fd to select() a specified fd. The function
6767 returns after timeout expires or data arrives or goes. The
6768 function is used by packet routines to wait that all data is
6769 received from network.
6771 * Fixed data reading from network in lib/silccore/silcpacket.c.
6772 The code now assures that all data is read from the fd and then
6773 continues packet processing. This was a bug fix since the code
6774 used to drop some data in some circumstances.
6776 * Added new function into lib/silcclient/client.[ch]:
6777 silc_client_start_key_exchange to start key exchange after
6778 connection has been established to server. The code internally
6779 now uses this funtion but its main purpose was to provide it
6780 for applications that perform their own connecting. After
6781 application has created a connection it merely calls this
6782 function to start the key exchange between client and server.
6783 The library takes care of everything else after that.
6785 Updated also lib/silcclient/README to explain the usage of
6788 * Do not send to application information that connection has
6789 been established. Application gets notified it by connect
6792 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6794 * Applied cras's patch to add silc_schedule_one function. The
6795 function runs scheduler once and returns.
6797 * Fixed the scheduler after cras messed it up. The timeout
6798 handling works now as it's supposed to work.
6800 * Added into lib/silccore/ silcnotify.h to include notify
6801 message types support. Changed silc_server_send_notify*
6802 functions, in server.[ch], to support those new notify types.
6803 Added the support for the notify types into client library,
6804 as well. Added new notify client operation into ops.h in
6807 * Changed silc_server_packet_send_to_channel to send normal
6808 packets instead of just channel message packets. The function
6809 is now used to send the notify packets to channels. It is not
6810 used to send channel message packets anymore, as server never
6813 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6814 va_arg()s as it seems to require it nowadays. I guess, if SILC
6815 is compiled with older va_arg() the new code should work anyway.
6817 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6819 * Splitted core library. Core library (lib/silccore) includes
6820 now only SILC protocol specific core (and common) components.
6821 Created new utility library (lib/silcutil) that includes more
6822 generic purpose stuff. The stuff for util library was taken
6823 from the old core library. This was minor and easy split.
6825 * Created SILC Client Library (lib/silcclient) that includes
6826 implementation of the SILC client without user interface. This
6827 was major move from silc/ directory. The code has been changed
6828 so that it is transparent towards the user interface. The
6829 silc/ directory includes now the same user interface as before
6830 and it uses the new client library. Read lib/silcclient/README.
6831 Basicly, the client library performs everything else related
6832 to SILC except user interface handling. Also, configuration
6833 files are considered to be part of user interface and library
6834 does not handle them.
6836 This change also changed a lot of structures, function naming etc.
6837 Most important change was that SilcClientWindow object was
6838 renamed to SilcClientConnection in the client library. Created
6839 also new file lib/silcclient/ops.h. Also added new files
6840 silc/local_command.[ch] and silc/client_ops.[ch].
6842 All these changes were made to make it easier for user interface
6843 designers to create what ever user interface for the SILC client
6846 It is also expected that the server will be moved to lib
6847 directory as well and SILC Server Library will be created;
6848 sometimes in the future.
6850 * Removed Local commands from lib/silccore/silccommand.h as
6851 they are application specific and new client library does not
6852 handle any of those anymore.
6854 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6855 old client implementation in silc/.
6857 * Added support for callback functions in SILC_LOG_* macros.
6858 Application can now set its own callbacks that will be called
6859 instead of using the default functions that will always print
6860 the debug messages to stderr (or stdout). Also, debugging can
6861 now be disabled by setting silc_debug to FALSE and re-enabled by
6862 setting it to TRUE. Note, that logging will still work even
6863 if debugging is disabled.
6865 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6866 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6867 silc_log_reset_debug_callbacks.
6869 * To enable debugging in silc client one must give now -d
6870 option on command line.
6872 * Changed silc_schedule_init to automatically allocate task queues
6873 if they are not allocated before calling it.
6875 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6877 * Added GMP 3.1 into math library.
6879 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6881 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6882 a channel in SILC network. The packet is used by servers and
6883 routers to notify other routers that user has left a channel.
6884 This little feature was missing until now. Added the feature
6885 to protocol specification as well.
6887 Added functions: silc_server_send_remove_channel_user and
6888 silc_server_remove_channel_user into server.[ch].
6890 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6891 lib/silccore/silcpacket.h. However, they are not implemented
6894 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6896 * Fixed joining to a channel and sending channel messages
6897 between server and router. The channel message sending should
6898 now work inside a cell.
6900 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6902 * Fixed the private message sending between server and router.
6903 The private message sending should now work inside a cell.
6905 * Added silc_server_replace_id into server.[ch] to replace
6906 existing ID in the SILC network.
6908 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6909 and silc_idlist_replace_server_id into idlist.[ch] in server.
6911 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6913 * Fixed the server to server connections. Server can again now
6914 connect to router. Router to router connections probably does
6917 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6919 * Added dynamic protocol registering support. Now protocols can
6920 registered and unregistered on the fly. Patch by cras.
6922 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6924 * Added lib/contrib directory to hold routines that some platforms
6925 don't have but are needed by SILC.
6927 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6928 into lin/contrib to provide getopt() and getopt_long() for
6929 those who don't have it.
6931 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6933 * Added AWAY command to client. When away message is set and
6934 client receives a private message packet the client automatically
6935 replies to the sender with the away message.
6937 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6938 bug seemed to be the cause of recent problems when compiling
6941 * Added version detection support to SKE protocol specification
6942 and added the new changes to the SKE implementation as well.
6943 There were other minor changes in the SKE protocol as well.
6945 Many changes in lib/silcske/silcske.[ch] and in
6946 lib/silcske/payload.[ch].
6948 * Added ^U functionality, clear input line. Patch from cras.
6950 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6952 * Mainly small bugfixes on core library. Fixed some debugging
6953 logging and buffer overflow in silclog.c.
6955 * Updated config.sub and config.guess on the distribution tree.
6957 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6959 * Added command lagging support in server. Client may execute
6960 commands now only once in two seconds.
6962 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6964 * Optimized packet reception. MAC computation and checking is now
6965 also more optimized. A lot previously duplicated code is now
6966 used as generic by both client and server.
6968 * Fixed key pair generation in clientutil.c
6970 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6972 * Added into lib/silccore/silcbufutil.[ch] new function;
6973 silc_buffer_realloc.
6975 * Moved generic packet sending/encryption functions to
6976 lib/silccore/silcpacket.[ch] from client and server. Some
6977 rewriting of the functions.
6979 * Moved all generic packet reception/decryption functions to
6980 lib/silccore/silcpacket.[ch] from client and server. The
6981 packet processing is now much cleaner in both client and server.
6982 These were major changes in both client and server.
6984 * Created many common functions in server to do packet sending.
6985 Previously code were duplicated a lot, this has been removed
6988 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6990 * Rewrote major parts of the ID cache system. Don't know
6991 whether it is better now or not but at least the API is more
6994 * Major rewrite on ID cache stuff on client because of the ID
6995 cache API changes. Added idlist.c to client.
6997 * Also major rewrite on ID cache stuff on server as well.
6998 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6999 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7000 in hand, instead they are all put into the ID cache system now.
7001 All server_idlist_* routines uses ID cache now instead of
7002 traversing its own lists (those lists does not exist anymore).
7003 SilcIDList though still exists. Also, SilcXXXEntry's are
7006 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7008 * Finally made the SKE implementation compliant to the protocol
7009 specification. All mp integers are now binary encoded as
7010 opposed being HEX encoded.
7012 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7015 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7016 functions: silc_[encode/decode]_pem. Also added function
7017 silc_encode_pem_file to PEM encode with newlines ('\n') for
7020 * SILC public keys are now encoded either PEM or binary. Same
7021 option is for private keys as well. By default private keys
7022 are binary encoded and public keys PEM encoded. Silly HEX
7023 encoding were removed.
7025 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7026 function to create fingerprints.
7028 * Fixed a bug in SHA1; does not change the original data anymore.
7030 * Partly implemented INFO command on client and server side.
7031 Fixed CLEAR command. Changes to SERVER command; show current
7032 server(s) when giving command without arguments. Added
7033 VERSION command to client.
7035 * Added check to server that unregistered connections cannot
7036 execute commands (unless it is specificly allowed).
7038 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7040 * Fixed screen refresh.
7042 * Fixed channel joining bug from client. On some circumstances
7043 client tried to join to a channel it had already joined.
7045 * Added public key verification process into client's protocol.c.
7046 The client now verifies the public key from user and saves
7047 it into ~./silc/serverkeys/ directory.
7049 Added into: clientutil.[ch]: silc_client_verify_server_key.
7051 * Changed SKE protocol's silc_ske_initiator_finish function
7052 to accept callback function that verifies the received public
7053 key. Removed old silc_ske_verify_public_key function.
7055 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7057 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7058 silc_pkcs_private_key[_data]_set.
7060 * Made the password and public authentication more cleaner in
7061 server's protocol.c.
7063 * Removed historic and obsolete protocol `channel_auth' from
7064 both client and server.
7066 * Removed wrong way of sending command status messages from
7067 server to client in server's command.c. The old way violated
7068 protocol specification.
7070 Changes to silccore/silccommand.[ch]: removed
7071 silc_command_encode_status_payload -> not needed anymore,
7072 changed silc_command_encode_payload_va to accept extra
7073 argument on variable argument list. The argument type must
7074 now be provided to the function. Also, added new function:
7075 silc_command_encode_reply_payload_va which is same as
7076 normal command_encode_payload_va except command status type
7077 is provided as extra argument.
7079 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7081 * Added ~./silc directory handling. The directory includes the
7082 public and private keys for the client.
7084 Added silc_client_check_silc_dir, silc_client_create_identifier
7085 and silc_client_load_keys.
7087 * Implemented SILC protocol compliant public key. Added public
7088 and private key saving to and loading from files.
7090 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7091 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7092 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7093 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7094 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7096 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7097 silc_pkcs_load_[public/private]_key.
7099 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7101 * Added silc_server_get_route (route.[ch]) to get connection
7102 data for the fastest route for given ID.
7104 * Implemented INVITE command on client and server. The command
7105 were re-defined in the SILC Protocol Specification and the
7106 implementation now complies with the specification.
7108 * Implemented PING command on client and server.
7110 * Implemented NAMES command on client and server. The server side
7111 supports currently only normal server not router server yet.
7112 Some changes to NAMES definition in SILC protocol specification.
7114 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7116 * Implemented LEAVE command on client and server.
7118 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7119 again. This change was made to the protocol as well. Server
7120 should not violate the protocol specification anymore.
7122 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7124 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7125 was tested. SOCKS4 was not but should work anyway.
