37 initiator and when accepting connections as responder.
39 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
40 whether given configuration value has been given already.
42 Affected files silcd/serverconfig.[c], server.[c].
44 * Splitted the doc/example_silcd.conf.in. Separated the crypto
45 algorithm parts and created new file silcalgs.conf, that
46 is now included from the example_silcd.conf.in.
48 * Optimized the silc_server_connect_to_router_second to take
49 the connection configuration object from the SilcServerConnection
50 object instead of finding it during the connecting phase.
51 Added the configuration object to SilcServerConnection struct.
52 Affected files silcd/server_internal.h, server.c.
54 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

76 authentication to be set at the same time.
78 Added `prefer_passphrase_auth' setting in config file which
79 can be used to set to prefer passwd auth if both passwd and
80 public key is set. If not set, public key is preferred.
81 This has effect only when being initiator (responder will try
84 Added support for authentication with passphrase and public key
85 at the same time. The passphrase is tried first always since
86 it is faster to check.
88 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
90 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
92 * Merged the new SILC Config library, with the server parsing

132 hash algorithm. Affected file lib/silccrypt/silcrng.c.
134 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
136 * Fixed the file transfer's key agreement payload to include
137 zero port also if the hostname is NULL because it could not
140 Call file transfer monitor callback now also if error occurs
141 during key agreement protocol.
143 Changed the silc_client_file_send interface to return the
144 SilcClientFileError instead of session id. The session ID
145 is returned into pointer provided as argument.
147 Check that the file exists locally before sending the
148 file transfer request at all.
150 Affected file lib/silcclient/client_ftp.c, silcapi.h.
152 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

162 file lib/silcutil/silclog.c.
164 * Fixed the channel message payload decryption in the function
165 silc_channel_message_payload_decrypt to not modify the original
166 buffer before it is verified that the message decrypted
167 correctly. Otherwise, next time it is called with correct
168 channel key it won't encrypt since the payload is corrupted.
169 Affected file lib/silccore/silcchannel.c.
171 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

183 * Fixed a bug in hash table internal routine for traversing
184 the table with foreach callback. The current entry may
185 become invalid in the callback but it was referenced after
186 the callback returned.
188 Do not allow auto rehashing of hash table during the
189 silc_hash_table_foreach operation, for same reasons as it is
190 not allowed for SilcHashTableList. Affected files are
191 lib/silcutil/silchashtable.[ch].
193 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
195 * Defined DLLAPI into silcincludes.h and silcwin32.h for

199 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
201 * Fixed private message handling. It used some old code that
202 caused the client to crash. Affecte file is
203 lib/silcclient/client_prvmsg.c.
205 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
207 * Added function silc_client_add_channel,
208 silc_client_replace_channel_id, and removed functions
209 silc_client_new_channel_id and silc_idlist_get_channel_by_id
212 * Added cross reference of the joined channels to the
213 SilcClientEntry, and changed the SilcChannelEntry's
214 users list to SilcHashTable. The affected files are
215 lib/silcclient/idlist.[ch].
217 * Fixed a bug in hash table tarversing. While the hash table
218 is traversed with SilcHashTableList the table must not be
219 rehashed. It is now guaranteed that auto rehashable tables
220 are not rehashed while tarversing the list. Also defined that
221 silc_hash_table_rehash must not be called while tarversing
222 the table. Added function silc_hash_table_list_reset that must
223 be called after the tarversing is over. The affected files are
224 lib/silcutil/silchashtable.[ch].
226 * Changed all hash table traversing to call the new
227 silc_hash_table_list_reset in server and in client library.
229 * Added function silc_client_on_channel to return the
230 SilcChannelUser entry if the specified client entry is joined
231 on the specified channel. This is exported to application as
232 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
234 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
236 * Fixed founder regaining problem with JOIN command on normal
237 server. The notify for mode change must be sent always and
238 not only if !cmd->pending. Affected file silcd/command.c.
240 * Fixed the WHOWAS command's reply sending to support the
241 lists correctly. Affected file silcd/command.c.
243 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
245 * When sending JOIN command to router for processing the
246 sender's old command identifier was not saved back to the
247 sender's command context, fixed now. The affected file is
250 * Create the key in JOIN command of the router did not return
251 the channel key, added check for this. Affected file is
254 * Fixed a channel ID update bug in JOIN command reply. Do
255 not directly upgrade the ID but call the function
256 silc_idlist_replace_channel_id if the ID was changed.
257 Affected file silcd/command_reply.c.
259 * Fixed memory leaks from command calling if it would fail.
260 Affected file silcd/command.c.
262 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

266 Memory leak fixes around libaries, irssi window resize fix,
267 new silclist.h and silcdlist.h, all extern inline changed to
270 * Removed dotconf from lib/dotconf, not needed anymore.
272 * Removed TRQ from lib/trq, not needed anymore.
274 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
275 with server connections. Later this will be configurable
276 in config file after new config file is done. Affected file
279 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
281 * Fixed a crash in server related to channel announcements.
282 Affected file silcd/server.c.
284 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
286 * Fixed memory leaks in silc_server_create_new_channel*
287 functions. Affected file silcd/server.c.
289 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
290 which ID was changed. This way the router will send the
291 user list for the channel again, and server won't be in
292 desync in some rare circumstances. Affected file is
293 silcd/packet_receive.c.
295 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
297 * Check for NULL socket pointer in the function

304 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
306 * Fixed some header addition to Toolkit distribution in
307 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
309 * Added lib/silcclient/client_ops_example.h as an template
310 file for application programmers to quickly start using
311 the SilcClientOperation functions in their application.
312 Updated the lib/silcclient/README as well to tell about this
313 nice file made available.
315 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
317 * Call silc_server_remove_from_channels when removing client
318 entry when NO_SUCH_CLIENT_ID was received. Affected file
319 is silcd/command_reply.c.
321 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
323 * Added server & router operator statistics updating. Affected
324 file silcd/packet_receive.c and silcd/command.c.
326 * Fixed the SERVER_SIGNOFF notify handling on normal server
327 not to save the history information for clients. Same was
328 fixed earlier in remove_clients_by_server function, but not
329 here. Affected file silcd/packet_receive.c.
331 * Raised the default connection-retry count from 4 to 7 in
332 server. Affected file silcd/server.h.
334 * Cancel any possible reconnect timeouts when we start the
335 key exchange. Affected file silcd/server.c.
337 * Do not reconnect on connection failure when SCONNECT was
338 given. Affected files silcd/server.[ch].
340 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
342 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
344 * Fixed the NICK command to always give the unformatted
345 nickname to the one giving the NICK command. If unformatted
346 nickname is cached already it will be formatted and the
347 local entry will always get the unformatted nickname.
348 Affected file lib/silcclient/idlist.c.
350 * Fixed some double frees from client library commands.
351 Affected file is lib/silcclient/command.c.
353 * Fixed CUMODE command in server to assure that no one can
354 change founder's mode than the founder itself, there was a
355 little bug. Affected file silcd/command.c.
357 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
359 * Removed the SilcClientCommandDestructor from the client
360 libary, it is not needed anymore. Affected files are
361 lib/silcclient/silcapi.h, command[_reply].[ch],
362 client_notify, idlist.c.
364 * Fixed GETKEY command to first resolve client, and then
365 resolve the server only if the client was not found, instead
366 of resolving both at the same time. Affected file is
367 lib/silcclient/command.c.
369 * Added silc_client_start_key_exchange_cb and lookup the
370 remote hostname and IP address before starting the key
371 exchange with server. The affected file is
372 lib/silcclient/client.c.
374 * The server's public key is now saved using the IP address
375 of the server and not the servername for the filename.
376 The hostname public key filename is checked as an fall back
377 method if the IP address based filename is not found.
379 Fixed the GETKEY command to save the fetched server key
382 Print the remote server's hostname now when new key is
383 received during connection process. Affected file is
384 irssi/src/silc/core/client_ops.c.
386 * Return always our own public key to the client if it asks
387 for it with GETKEY command. Affected file silcd/command.c.
389 * Removed the use_auto_addr variable from default config
390 file since it was in wrong section. Affected file is
393 * Fixed TOPIC_CHANGE notification to not route it when it
394 was sent using silc_server_send_notify_to_channel function.
395 Affected file silcd/command.c.
397 * Fixed silc_server_send_notify_kicked to send the kicker's
398 Client ID also, it was missing. Affected files are
399 silcd/command.c, silcd/packet_send.[ch].
401 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
403 * Do not save client history information in SERVER_SIGNOFF.
404 Fixes the bug in normal server that it does not detect
405 the client becoming valid after the server becomes back
406 online. Affected file silcd/server_util.c.
408 * Added `sock_error' field into the SilcSocketConnection
409 context. When error occurs during socket operation (read
410 or write) the error is saved. Added also new function
411 silc_socket_get_error to return human readable socket error
412 message. Affected files are lib/silcutil/silcsockconn.[ch],
413 lib/silcutil/unix/silcunixsockconn.c, and
414 lib/silcutil/win32/silcwin32sockconn.c.
416 * The server now prints the socket error message in the
417 signoff for client. Affected file silcd/server.c.
419 * Fixed the `created' channel information sending from router
420 to server in JOIN command. Checks now whether the channel
421 really was created or not and set it according that.
423 Fixed the JOIN command to use the client entry's current
424 ID during the joining procedure instead of the one it sent
425 in the command (it is checked though), since it can change
426 between the packet processing and command processing, and
427 would just case unnecessary pain in the client end. Affected
428 file silcd/command.c.
430 * Fixed a channel key payload sending to use correct channel
431 ID when the server was forced to change the channel's ID by
432 router. Router sent the key payload with the old Channel ID.
433 Affected file silcd/packet_receive.c.
435 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
437 * Call silc_server_save_channel_key only if the key payload
438 was provided in the JOIN command's command reply. Affected
439 file silcd/command_reply.c.
441 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
443 * Fixed silc_mp_sizeinbase to return the value correctly with
444 MPI. Affected file lib/silcmath/mp_mpi.c.
446 * Fixed the stop_server signal to correctly stop the scheduler
447 and gracefully stop the server when SIGTERM or SIGINT signals
448 are received. Affected file silcd/silcd.c.
450 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
452 * Simple handling of TERM and HUP signals. Also added some log
453 flushing call around. Affected file is
456 * Fixed small bugs in silclog.c. Now buffering output will take
457 effect after 10 seconds since startup: This will ensure that
458 no important startup messages are lost. Also output redirection
459 will preserve original format ([Date] [Type] message).
460 Affected file is lib/silcutil/silclog.c.
462 * Added two options to the config file, in the logging section:
463 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
464 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
466 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
468 * Do not print the warning about log files not being initialized
469 more than once to avoid excess logging. Affected file is
470 lib/silcutil/silclog.c.
472 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
473 the SIM copying in make install in Makefile.am.pre.
475 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
477 * Rewritten silclog APIs. Globally interesting changes follows:
478 silc_log_set_files() changed to silc_log_set_file().
479 silc_log_set_callbacks() changed to silc_log_set_callback().
480 ROBOdoc documented silclog header file.
481 SilcLogCb now returns bool to wether inihibit the default
482 handler or not (to keep the old behaviour return always TRUE).
483 The new APIs should also fix the problem of the
484 silcd_error.log file that was written in the current directory.
487 Log files streams will remain opened after silc_log_set_file()
488 call, means less CPU usage notably on high traffic servers.
489 File streams are now full buffered, and flushed to the disk
490 every 5 minutes, lesses HD activity and CPU usage.
491 Messages can be redirected, allowing admins to configure
492 one single logfile for all server messages.
493 the silc_log_quick global variable to activate fast-logging.
494 Affected files lib/silcutil/silclog.[ch]
496 * Changed some code to conform new silclog APIs. Affected
497 files are doc/example_silcd.conf.in, silcd/server.c
498 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
501 * Fixed a memory leak that could occur in some situations.
502 Affected file silcd/serverconfig.c.
504 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
506 * Added the silc_client_del_client to remove the client from
507 all channels as well. Affected file lib/silcclient/idlist.c.
509 * Fixed the client library to correctly remove the client
510 from all channels when the client entry is being destroyed.
511 Affected file lib/silcclient/client_notify.c, command.c.
513 * Added auto-nicking support to the client library. If the
514 applicatio now sets client->nickname it will be sent to the
515 server after connecting by the library. This way for example
516 SILCNICK (or IRCNICK) environment variables will have effect
517 and always change the nickname automatically to whatever
518 it is wanted. Affected file lib/silcclient/client.[ch].
520 * Renamed silc_server_command_bad_chars to the
521 silc_server_name_bad_chars and moved it to the
522 silcd/server_util.[ch]. Added also new function
523 silc_server_name_modify_bad to return nickname that
524 includes bad characters as new nickname without those
525 bad characters. This check and modify is now used in
526 silc_server_new_client when the username is initially set
527 as nickname, so it must be checked to be valid nickname.
528 Affected file silcd/packet_receive.c.
530 * The nickname length is now taken from the packet for real
531 and not trusted to strlen() since it clearly can return
532 wrong length for nickname including bad characters. This
533 also applies to channel names. Affected file silcd/command.c.
535 * Removed the lib/silcsilm/modules directory. Modules are now
536 compiled into the lib/silcsim. Fixed the copying of the
537 modules to follow symbolic links in Makefile.am.pre.
539 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
541 * Fixed silc_string_regexify list creation. Fixes bugs with
542 BAN and INVITE commands in server. The affected file is
543 lib/silcutil/unix/silcunixutil.c.
545 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
547 * Removed the command destructor entirely from the server's
548 command and command reply routines. It is not needed, and
549 its usage was buggy and caused crashes. Affected files are
550 silcd/command[_reply].[ch].
552 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
554 * Cancel protocol and NULL sock->protocol if timeout
555 occurred during protocol. Affected file silcd/server.c.
557 * Cancel protocol timeouts always before calling the final
558 callback, to assure that after final callback is called
559 no other state will be called for the protocol anymore.
560 Affected file silcd/protocol.c.
562 * Print error log if incoming connection configuration could
563 not be found. Affected file silcd/server.c.
565 * Fixed JOIN command to correctly save the founder mode
566 to the client on normal SILC server, when the channel
567 was created by the router. Affected file silcd/command.c.
569 * Fixed LIST command (hopefully) to send correct reply
570 packets. Affected file silcd/command.c.
572 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
574 * The silc_packet_receive_process now returns FALSE if the
575 read data was invalid packet, and TRUE if it was ok.
577 The server now checks that if unauthenticated connection
578 sends data and its processing fails the server will close
579 the connection since it could be a malicious flooder.
581 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
583 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
585 * Make sure the warning about error opening a log file is
586 printed only once and not everytime it fails (produces
587 too much useless log). Affected file lib/silcutil/silclog.c.
589 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
591 * Made the silc_server_daemonise() function more readable.
592 Affected file silcd/server.c.
594 * Pid file is now optional, the user may comment it out from
595 the config file. Removed define SILC_SERVER_PID_FILE, we
596 don't need a default any longer. Affected file
597 configure.in.pre, lib/Makefile.am.pre.
599 * Make some use of the pid file. The server now dies at startup
600 if it detects a valid pid file on his path. The server would
601 die anyway in this circumstance, because of the bind() failure.
602 Affected file silcd/silcd.c.
604 * No longer compiling lib/dotconf.
606 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
608 * Fixed JOIN command parsing not to crash. Affected file
609 lib/silcclient/command.c.
611 * Fied the NICK_CHANGE notify to add the new client entry
612 even it is resolved. This removes an <[unknown]> nick
613 thingy bug in the client. Affected file is
614 lib/silcclient/client_notify.c.
616 * Do not try to allocate 0 bytes (efence does not like it)
617 in lib/silccore/silccomand.c when encoding payload.
619 * Do not take IRCNICK as nickname in Irssi SILC client since
620 it is not possible to set nickname before hand connecting
621 the server (TODO has an entry about adding auto-nicking
624 * Changed the silc_server_command_pending to check whether
625 there already exists an pending entry with the specified
626 command, command identifier and pending callback. This is
627 to fix IDENTIFY and WHOIS related crashes that may register
628 multiple pending commands with same identifier. Affected
629 file silcd/command.c.
631 * Fixed the server to reconnect to the router even if it
632 was already reconnecting and EOF was received. This to
633 fix a possibility that the server wouldn't ever try to
634 auto-reconnect to the router. Affected file silcd/server.c.
636 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
638 * Fixed the server's password authentication to use the
639 length of the locally saved password, and not the one
640 sent in the packet. Affected file silcd/protocol.c.
642 * Fixed same password authentication problem in the
643 Authentication Payload handling routines in
644 lib/silccore/silcauth.c.
646 * Yet another password authentication problem fixed with
647 channel password handling in silcd/command.c.
649 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
651 * If first character of string in silc_parse_userfqdn is '@'
652 then do not parse it. Affected file is
653 lib/silcutil/silcutil.c.
655 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
657 * Fixed minor bug in IDENTIFY command reply sending, which
658 caused various weird problems during JOIN when it was
659 resolving names for users. Affected file silcd/command.c.
661 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
663 * Fixed the IDENTIFY command reply sending to chech better valid
664 clients. It was possible to send incomplete list of replies.
665 Affected file silcd/command.c.
667 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
669 * Added silc_client_command[s]_[un]register functions now to
670 dynamically register the commands in client library. Removed
671 the static table of commands. This allows the client library
672 to call commands without causing the application to know about
673 what commands library has called.
675 Removed the INFO command reply kludge to detect when the command
676 was called by library. Now library use its own command reply
677 function for INFO command.
679 Added function silc_client_command_call to call a command.
680 Application can use it to call command, not access the structure
683 Now all commands that are sent by the client library (not
684 explicitly sent by application) use own command reply functions.
686 Affected files around lib/silcclient/ and in
687 irssi/src/silc/core/.
689 * Fixed the WHOIS command reply sending to chech better valid
690 clients. It was possible to send incomplete list of replies.
692 Fixed the WHOIS and IDENTIFY to send the request to router
693 if normal server did not do it and did not find any results.
695 Affected file silcd/command.c.
697 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
699 * Moved the internal data from SilcClient context into its
700 own file, not accesible to application. Affected files
701 lib/silcclient/client.h and lib/silcclient/client_internal.h,
702 and other files in client library.
704 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
706 * Added doc/examples installation target in Makefile.am.pre.
709 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
711 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
712 commands the found client entry will be removed from the
713 cache, after notifying application about the error. Affected
714 file lib/silcclient/command_reply.c.
716 * Changed the /MSG to check for exact nickname user gave, and
717 not let `nick' match `nick@host' if it is only one found. Now,
718 user must type the exact nickname (like nick@host2) even if
719 there are no more than one same nicks found. This is to avoid
720 a possibility of sending nickname to wrong nickname since
721 `nick' could match `nick@host'. Affected file is
722 irssi/src/core/silc-servers.c.
724 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
726 * Do not print "you are now server operator" or similar when
727 giving /away command. Affected files are
728 irssi/src/silc/core/client_ops.c, silc-servers.h.
730 * Made the silc_server_command_pending_error_check to send
731 the same command reply payload it received back to the
732 original sender of the command. This way all arguments
733 that was received by the server will be received by the
734 client too. Affected file silcd/command.c.
736 * Added the silc_idcache_add to return the created cache entry
737 to a pointer. Affected file lib/silccore/silcidcache.[ch].
739 * Add global clients to expire if they are not on any channel.
740 This is because normal server will never know if they signoff
741 if they are not on any channel. The cache expiry will take
742 case of these entries. This is done by normal servers only.
743 The affected files are silcd/command_reply.c,
744 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
746 * If server receives invalid ID notification for WHOIS or
747 IDENTIFY and the ID exists in the lists, it is removed.
748 Affected file silcd/command_reply.c.
750 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
751 in client then client entry that it matches is searched and
752 the nickname is printed on the screen for user. Affected
753 file irssi/src/silc/core/client_ops.c.
755 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
757 * Use cache entry expire time in the LIST command reply to
758 purge old entries from the cache after the LIST command
759 reply has been received. This way we don't have non-existent
760 entries in the cache for too long. Affected file is
761 silcd/command_reply.c.
763 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
765 * If we are normal server, and we've not resolved client info
766 in WHOIS or IDENTIFY from router, and it is global client,
767 we'll check whether it is on some channel. If it is not
768 then we cannot be sure about its validity and will resolve it
769 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
770 file silcd/command.c.
772 * Search channel by name (if possible) rather than by ID
773 in IDENTIFY command's command reply. Affected file is
774 silcd/command_reply.c.
776 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
778 * Distribute to the channel passphrase in CMODE_CHANGE notify.
779 Updated specs and implemented it. Affected file silcd/command.c,
780 silcd/packet_send.c and silcd/packet_receive.c.
782 * Implemented the <founder auth> payload handling in the JOIN
783 command. If provided all conditions for channel joining
784 except requirement to provide correct passphrase can be
785 overrided by the channel founder. Updated the protocol specs.
786 Affected file silcd/command.c.
788 Added support for founder auth in JOIN command in client
789 library. Fixed the parsing of the JOIN command now to support
790 all options as they should be. The affected file is
791 lib/silcclient/command.c.
793 * Optimized the WHOIS and IDENTIFY commands to send the request
794 to router only if it includes nicknames or other names. If
795 they include only IDs then check the local cache first before
796 routing. Affected file is silcd/command.c.
798 * Added channels topic announcements. Affected file is
799 silcd/packet_receive.c and silcd/server.c.
801 * Fixed the silc_server_send_notify_topic_set to really destine
802 the packet to channel. Affected file silcd/packet_send.c.
804 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
805 library. Affected file lib/silcclient/client_notify.c.
807 * Added UMODE announcements. Affected file silcd/server.c.
809 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
811 * Memory leak fixes in:
813 lib/silcutil/silcsockconn.c
814 lib/silcske/silcske.c
817 lib/silccrypt/silcpkcs.c
818 lib/silccore/silccommand.c
819 lib/silccore/silcidcache.c
824 * ROBOdoc documented the lib/silcske/groups.h file and a
825 bit changed the interface for better.
827 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
829 * Update the client entry context in the ID cache after
830 nick change. Affected file lib/silcclient/command.c.
831 Fixes the CUMODE command when regaining founder privileges,
832 and a little WHOIS problem.
834 * Fixed silc_net_gethostbyname to correctly call the
835 inet_ntop. Affected file lib/silcutil/silcnet.c.
837 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
839 * Added IPv6 support checking to the configure.in.pre, added
840 also --enable-ipv6 option to override the check. Affected
841 file configure.in.pre.
843 * The silc_thread_create now calls the start function
844 directly if threads support is not compiled in. Removes
845 ugly #ifdef's from generic code. Affected files are
846 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
848 * Added silc_net_gethostby[name/addr]_async to asynchronously
849 resolve. Affected files are lib/silcutil/silcnet.[ch].
851 * Added support for rendering IPv6 based server, client and
852 channel IDs. Affected file lib/silcutil/silcutil.c.
854 * Added support for creating IPv6 based server IDs. Affected
855 file is silcd/serverid.c.
857 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
859 * Added silc_net_gethostby[addr/name] into the
860 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
861 routines. Added silc_net_is_ip[4/6]. Affected file is
862 lib/silcutil/unix/silcunixnet.c. All routines that take
863 address as argument now supports both IPv4 and IPv6 addresses.
865 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
867 * Fixed LIST command reply sending in server. Affected file
870 * Server now sends the kicker's client ID in the KICK notify
871 to the kicked client. Affected file silcd/command.c.
873 * The client library now parses the kickers client ID and
874 UI displays it. Affected files lib/silcclient/client_notify.c
875 and irssi/src/silc/core/silc-channels.c, module-formats.c.
877 * Made all payload parsing function prototypes consistent.
878 They all take now const unsigned char * and uint32 pair as
879 the payload data instead of SilcBuffer. Changes all around
880 the source tree. Other unsigned char* -> const unsigned char*
881 changes around the tree as well.
883 * Optimized SFTP client and server packet sending not to
884 allocate new buffer for each packet but to recycle the
885 first allocated buffer. Affected files are
886 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
888 * Optimized the SFTP client to use SilcList instead of
889 SilcDList for requests, because it is faster. Affected file
890 is lib/silcsftp/sftp_client.c.
892 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
893 into lib/silccore/silcid.[ch].
895 Renamed silcpayload.[ch] into silcargument.[ch].
897 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
899 * If client entry is deleted with active key agreement
900 session, abort the session.
902 The silc_client_abort_key_agreement now calls the completion
903 callback with new SILC_KEY_AGREEMENT_ABORTED status.
905 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
908 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
910 * Don't use __restrict in older GCC's. Affected file is
911 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
913 * silc_net_localhost now attempts to reverse lookup the
914 IP/hostname. Affected file lib/silcutil/silcnet.c.
916 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
917 command. It can be used to gain founder privileges at
918 the same time when joining the channel.
920 Defined that the SILC_NOTIFY_TYPE_KICKED send the
921 kicker's client ID as well. Updated protocol specs.
923 Defined that the server must send SILC_COMMAND_IDENTIFY
924 command reply with error status to client who sent
925 private message with invalid client ID.
927 Updated the protocol specification.
929 * Added silc_server_send_command_reply to send any
930 command reply. Affected file silcd/packet_send.[ch].
932 * Added silc_id_payload_encode_data to encode ID payload
933 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
935 * The server now send IDENTIFY command reply with error
936 status if client ID in private message is invalid. Affected
937 file silcd/packet_receive.c.
939 * Save the server key file with server's IP address in
940 the filename instead of hostname. The affected file is
941 irssi/src/silc/core/client_ops.c.
943 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
945 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
948 * Added libtool support for compiling shared objects in
949 lib/silcsim. Affected file configure.in.pre and
950 lib/silcsim/Makefile.am. Original patch by cras.
952 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>

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

994 Affected file irssi/src/silc/core/client_ops.c.
996 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
998 * Fixed the silc_idcache_list_* routines to really support
999 the dynamic list. Fixes a crash. Affected file is
1000 lib/silccore/silcidcache.c.
1002 * Fixed the LIST command reply to really call LIST command's
1003 pending callbacks. Affected file silcd/command_reply.c.
1005 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1007 * Update conn->local_entry->nickname after giving NICK
1008 command. Affected file lib/silcclient/command.c.

1019 Affected file silcd/command_reply.c.
1021 * Fixed NICK commands pending callback registration.
1022 Affected file lib/silcclient/command.c.
1024 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1026 * Use ++server->cmd_ident when sending commands in server,
1027 instead of random number. Affected file silcd/command.c.
1029 * Fixed GETKEY command reply to call actually GETKEY pending
1030 command callbacks. Affected file silcd/command_reply.c.
1032 * A bit stricter check for nicknames. Check for same nickname
1033 in NICK command also. Affected file silcd/command.c.
1035 * Do not call INFO command everytime client ID changes, only
1036 during first connecting. Affected file lib/silcclient/client.c.
1038 * Set the new nickname only after successful command reply for
1039 NICK command is returned by server. Affected file
1040 lib/silcclient/command.c.
1042 * Remove nicknames from nicklist during server_signoff notify.
1043 Should fix /NAMES bit more. The affected file is
1044 irssi/src/silc/core/silc-channels.c.
1046 * Added `fingerprint' field to the SilcIDListData in the
1047 silcd/idlist.h to hold the fingerprint of the client's
1050 Send the fingerprint of the client's public key in WHOIS
1053 Affected files silcd/command.c, and silcd/idlist.[ch].
1055 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1056 create fingerprint from given data.
1058 * Show the fingerprint of the client's public key in WHOIS.
1059 Affected files irssi/src/module-formats.[ch] and
1060 irssi/src/silc/core/client_ops.c.
1062 * Format the multiple same nicknames also during JOIN and
1063 NICK_CHANGE notifys. Affected file is
1064 lib/silcclient/client_notify.c.
1066 * Do not print error on screen for invalid private message
1067 payload since it can come if someone is sending private
1068 messages with wrong key. Affected file
1069 lib/silccore/silcprivate.c.
1071 * Fixed multiple concurrent /PING crash. Affected file
1072 lib/silcclient/command.c.
1074 * Changed the wrong ID encoding. All IP addresses must be
1075 in MSB first order in encoded format. They were encoded
1076 wrong and was in LSB format. Affected files are
1077 silcd/serverid.c, lib/silcutil/silcutil.c.
1079 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1081 * Call the `connect' client operation through the scheduler
1082 in case of error. Affected file lib/silcclient/client.c.
1084 * Call the `failure' client operation even if the error
1085 occurred locally during a protocol. Affected file is
1086 lib/silcclient/protocol.c.
1088 * Added support of sending LIST command to router from normal
1089 server. This way normal server can get list of all channels
1090 in the network too. Fixed the channel list sending in the
1091 server too. Affected files are silcd/command.c, and
1092 silcd/command_reply.[ch].
1094 * Added silc_server_update_channels_by_server and
1095 silc_server_remove_channels_by_server. They are used during
1096 disconnection of primary router and in backup router protocol.
1097 Affected file silcd/server_util.[ch], silcd/server.c and
1098 silcd/server_backup.c.
1100 * Fixed channel adding to global list in IDENTIFY command
1101 reply in server. Affected file silcd/command_reply.c.
1103 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1105 * If the incoming packet type is REKEY or REKEY_DONE process
1106 that packet always synchronously. Fixes yet another MAC
1107 failed error on slow (dialup) connections. Affected file
1108 lib/silcclient/client.c and silcd/server.c.
1110 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1112 * Call check_version SKE callback for initiator too. Affected
1113 file lib/silcske/silcske.c.
1115 * Implemented fix for security hole found in the SKE that was
1116 fixed in the specification few days back; the initiator's
1117 public key is now added to the HASH value computation.
1118 Added backwards support for the old way of doing it too, for
1119 old clients and old servers. Affected file is
1120 lib/silcske/silcske.c.
1122 * Enabled mutual authentication by default in SKE. If initiator
1123 is not providing mutual authentication the responder will
1124 force it. This will provide the proof of posession of the
1125 private key for responder. The affected files are
1126 lib/silcclient/protocol.c and silcd/protocol.c.
1128 * Do not cache anymore the server's public key during SKE.
1129 We do mutual authentication so the proof of posession of
1130 private key is done, and if the server is authenticated in
1131 conn auth protocol with public key we must have the public
1132 key already. Affected file silcd/protocol.c.
1134 * Added new global debug variable: silc_debug_hexdump. If
1135 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1136 file lib/silcutil/silclog.[ch].
1138 * Fixed compilation warning due to char * -> const char *.
1139 Affected files lib/silcutil/silcnet.h, and
1140 lib/silccore/silcauth.[ch].
1142 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1144 * Fixed CMODE command when new channel key was created. If
1145 the creation failed the old key was removed. Next time giving
1146 same command would crash the server since the old key was
1147 freed already. Affected file silcd/command.c.
1149 * Fixed the silc_server_announce_get_channels to not crash
1150 on reconnect. Affected file silcd/server.c.
1152 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1154 * Added silc_log_set_debug_string function to set a regex
1155 string to match for debug output. Only the function names,
1156 or filenames matching the given debug string is actually
1157 printed. This way it is possible to filter out those debug
1158 strings that user is not interested in.
1160 Fixed a bug in silc_string_regexify.
1162 Affected files lib/silcutil/silclog.[ch], and
1163 lib/silcutil/unix/silcunixutil.c.
1165 * Changed the -d options in both server and Irssi SILC client
1166 to take the debug string as argument. Affected files
1167 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1169 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1171 * Added silc_hash_babbleprint to create a Bubble Babble
1172 Encoded fingerprint. The encoding is developed by Antti
1173 Huima (draft-huima-babble-01.txt), and it creates human
1174 readable strings out of binary data. Affected file
1175 lib/silccrypt/silchash.[ch].
1177 * Print the babble print now in addition of fingerprint as well
1178 in Irssi SILC client. Affected files are
1179 irssi/src/fe-common/silc/module-formats.[ch],
1180 irssi/src/fe-common/silc/core/client_ops.c.
1182 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1184 * Fixed a security problem found in SKE. The initiator's
1185 public key too is now added to the HASH hash value creation
1186 which is signed by the responder to create the SIGN value.
1187 This will prevent anyone in the middle to lie to the responder
1188 about the initiator's public key. If this is done now, the
1189 man in the middle will get caught. Updated the protocol
1192 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1194 * Better installation directory handling. Configure module
1195 paths and other paths automatically to example_silc* files
1196 in doc/. A patch by toma.
1198 * Fixed compiler warning from MPI library, and from SILC RNG.
1201 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1202 It can be configured with ./configure. A patch by toma.
1204 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1206 * Find correct make to use in prepare-clean. A patch by
1207 toma. Affected file prepare-clean.
1209 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1211 * Added irssi variables use_auto_addr, auto_bind_ip,
1212 auto_bind_port and auto_public_ip.
1214 * Changed the interface for silc_client_send_key_agreement
1215 in lib/silcclient/silcapi.h
1219 irssi/src/silc/core/silc-core.c
1221 lib/silcclient/silcapi.h
1222 irssi/src/silc/core/silc-channels.c
1223 lib/silcclient/client_keyagr.c
1226 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1228 * Added silc_pkcs_public_key_compare to compare two
1229 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1231 * Check that the client who set the founder mode on the
1232 channel is the same client that is giving the founder
1233 mode to itself. It is done by comparing the saved public
1234 key (it is saved even in the authentication is passphrase).
1235 Affected file silcd/command.c.
1237 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1239 * Do not process packet for disconnected socket connection.
1240 Affected file lib/silccore/silcpacket.c.
1242 * Process the DISCONNECT packet through scheduler in the
1243 client library. Affected file lib/silcclient/client.c.
1245 * Fixed the silc_client_packet_parse to not to increase
1246 the packet sequence number if the conn->sock and the
1247 current socket connection is not same. This can happen
1248 for example during key agreement when the conn includes
1249 multiple socket connections (listeners). Affected file
1250 lib/silcclient/client.c.
1252 * The sender of the file transfer request now provides also
1253 the pointer (listener) for the key exchange protocol. If
1254 the listener cannot be created then it sends empty key
1255 agreement and lets the receiver provide the listener.
1257 Added `local_ip' and `local_port' arguments to the
1258 silc_client_file_send. If they are provided they are used,
1259 if not then it will attempt to find local IP address, if
1260 not found or bind fails then the remote client will provide
1263 Affected files are lib/silcclient/client_ftp.c and
1264 lib/silcclient/silcapi.h.
1266 * Extended the FILE SEND command to support defining the
1267 local IP and port for key exchange listener. They are
1268 optional. Affected file irssi/src/silc/core/silc-servers.c.
1270 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1272 * Defined to WHOIS command reply the sending of fingerprint
1273 of the client's public key (if the proof of posession of the
1274 corresponding private key is verified by the server).
1275 Updated to the protocol specification.
1277 * Added support of receiving the client's public key's
1278 fingerprint in command reply in client library. Affected
1279 file is lib/silcclient/command_reply.c, and
1280 lib/silcclient/idlist.[ch].
1282 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1284 * Do not send over 128 chars long nickname to the server
1285 in NICK command. Affected file lib/silcclient/command.c.
1287 * Do not send over 256 chars long channel names to the server
1288 in JOIN command. Affected file lib/silcclient/command.c.
1290 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1292 * Assure that silc_server_close_connection cannot be called
1293 twice for same socket context. Affected file is
1296 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1298 * Send error message to application if opening file for
1299 writing during file transfer fails. Affected file is
1300 lib/silcclient/client_ftp.c.
1302 Remove all file transfer sessions for a client that we're
1303 removing from ID cache.
1305 Affected file is lib/silcclient/client_ftp.c.
1307 * Fixed silc_net_addr2bin to return correct address. Affected
1308 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1310 * Fixed file transfer session removing on signoff notify.
1311 Affected file irssi/src/silc/core/silc-servers.c.
1313 * Added the SilcClientFileError to be returned in the monitor
1314 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1315 Affected file lib/silcclient/silcapi.h.
1317 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * Fixed a crash in silc_client_ftp_free_sessions and
1320 silc_client_ftp_session_free_client. Affected file
1321 lib/silcclient/client_ftp.c.
1323 * Added `disabled' field in the SilcChannelEntry in the server
1324 to indicate if the server entry is disabled. Affected file
1325 silcd/idlist.h, silcd/command[_reply].c.
1327 * SILC server adds now /var/run/silcd.pid everytime it is
1328 started. Affected file silcd/silcd.c.
1330 * Added silc_server_packet_send_clients to send a packet to
1331 the provided table of client entries. Affected file
1332 silcd/packet_send.[ch].
1334 * Fixed a crash in client resolving in client_prvmsg.c in
1335 client library. Affected file lib/silcclient/client_prvmsg.c.
1337 * Do not actually remove the client directly from ID cache
1338 during SERVER_SIGNOFF, but invalidate it. This way we
1339 preserve the WHOWAS info for the client. Affected file
1340 silcd/server_util.c.
1342 * Fixed SERVER_SIGNOFF notify handling in the server. The
1343 server is now able to process incoming SERVER_SIGNOFF notify
1344 for a server that it doesn't even know about. It will remove
1345 the clients provided in the notify. Affected file
1346 silcd/packet_receive.c.
1348 * Check for partial packet in data queue after every packet that
1349 was found from the queue. Return and wait for more data if
1350 there is partial data in queue. Affected file is
1351 lib/silccore/silcpacket.c.
1353 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1355 * Added SilcClietFileError enum to indicate error in
1356 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1357 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1358 Affected files lib/silcclient/silcapi.h and
1359 lib/silcclient/client_ftp.c.
1361 * Check that newsize in silc_buffer_realloc is larger than
1362 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1364 * Added better monitor of file transfers. It now monitors
1365 key agreement protocol during the file transfer too. Added
1366 error reporting too. Affected files
1367 irssi/src/silc/core/silc-servers.c,
1368 irssi/src/fe-common/silc/module-formats.[ch].
1370 * Wrote a help file for FILE command.
1372 * Added silc_rng_global_get_byte_fast to get not-so-secure
1373 random data as fast as possible. Random data is read from
1374 /dev/urandom if available and from the SILC RNG if not
1375 available. It is used in padding generation. Affected file
1376 lib/silccrypt/silcrng.[ch].
1378 * All packets in client library are now processed synchronously.
1379 Optimized packet processing a lot. Affected file
1380 lib/silcclient/client.c.
1382 * All server connection packets are processing synchronously
1383 now in server, to optimize packet processing. Affected file
1386 * Include files are installed now only in Toolkit distribution
1387 if make install is given. Affected files: all Makefile.am's.
1389 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1391 * Assure that silc_client_notify_by_server_resolve does not
1392 resolve the client information multiple times. If it cannot
1393 be found by the first it cannot be found at all. Affected
1394 file lib/silcclient/client_notify.c.
1396 * Fixed WHOWAS command reply calling. Affected file
1397 lib/silcclient/command_reply.c.
1399 * Removed all references to silc_idlist_get_client from the
1400 Irssi SILC client since that call is internal call used by
1401 the library. The Irssi SILC client will use now client
1402 retrieval functions found in silcapi.h.
1404 * Fixed a bug in resolving nickname info before sending
1405 private message. It used freed memory. Affected file
1406 irssi/src/silc/core/silc-servers.c.
1408 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1410 * Assure my_channels statistics cannot go negative in server.
1411 Affected files silcd/server.c, silcd/server_util.c.
1413 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1415 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1417 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1419 * Win32 Toolkit changes. Affected files

1423 lib/sftp/sftp_fs_memory.c.
1425 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1427 * Added silc_net_localip to return local host's IP address.
1428 Affected file lib/silcutil/silcnet.[ch].
1430 * If key exchange or rekey protocol is active for a connection
1431 parse all packets syncronously since there might be packets
1432 in packet queue that we are not able to process without first
1433 processing packets before them. Affected file silcd/server,
1434 lib/silcclient/client.c.
1436 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1437 whether library should continue processing the packet.
1438 Affected file lib/silccore/silcpacket.h.
1440 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1441 SilcSFTPMonitorData to SFTP server to monitor various
1442 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1443 lib/silcsftp/sftp_server.c.
1445 * Added silc_file_size to return file size. Affected file
1446 lib/silcutil/silcutil.[ch].
1448 * Implemented the file transfer support for the client library.
1449 Added preliminary support for simple client to client one-file
1450 transmission. Affected file lib/silcclient/client_ftp.c,
1451 lib/silccilent/client.[ch].
1453 * Added new local command FILE to the Irssi SILC Client.
1454 It is used to perform the file transfer. It has subcommands
1455 SEND, RECEIVE, SHOW and CLOSE. Affected files
1456 irssi/src/silc/core/client_ops.c,
1457 irssi/src/silc/core/silc-server.[ch].
1459 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1461 * Relay the SILC_PACKET_FTP in the server. Affected files
1462 silcd/server.c and silcd/packet_receive.c.
1464 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1466 * Renamed silc_file_read and silc_file_write to functions
1467 silc_file_readfile and silc_file_writefile. Added function
1468 silc_file_open and silc_file_close. Affected files
1469 lib/silcutil/silcutil.[ch].
1471 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1473 * Resolve the client info when received private message or
1474 channel message for a client which nickname we don't know.
1475 Affected files lib/silcclient/client_prvmsg.c and
1476 lib/silcclient/client_channel.c.
1478 * Do not crash in /KEY if client is not connected. Affected
1479 file irssi/src/silc/core/silc-channels.c.
1481 * Added SilcClientStatus field to the SilcClientEntry in the
1482 lib/silcclient/idlist.h.
1484 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1485 is incomplete and is being resolved, it won't be resolved
1488 Make sure also that USERS command reply does not resolve
1489 twice information. Affected file is
1490 lib/silcclient/command_reply.c.
1492 Make sure that silc_client_get_clients_by_list does not
1493 resolve twice same information.
1495 * Check for valid client->id in the silc_server_free_client_data.
1496 Affected file silcd/server.c.
1498 * Fixed /GETKEY nick@server not to crash if the server entry
1499 is not found. Affected file lib/silcclient/command.c.
1501 * Fixed the silc_server_check_cmode_rights to check the
1502 requested modes correctly. Affected file silcd/command.c.
1504 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1506 * Better checks for non-printable chars in nick added.
1507 Affected file silcd/command.c.
1509 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1511 * Call the silc_server_udpate_servers_by_server in the
1512 primary router that comes back online in the backup resuming
1513 protocol. Otherwise it routes packets wrong. Affected file
1514 silcd/server_util.[ch], silcd/server_backup.c.
1516 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1518 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1519 lib/silcutil/silcbuffmt.[ch].
1521 * Redefined the SILC packet header to include the padding
1522 length. Affected file lib/silccore/silcpacket.[ch].
1524 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1525 length for maximum padding up to 128 bytes). Affected
1526 file lib/silccore/silcpacket.h.
1528 * Removed all backwards support for old 0.5.x MAC thingies.
1529 The SILC packet header change makes it impossible to be
1530 backwards compatible.
1532 * Send the ENDING packet with timeout in the backup resuming
1533 protocol. This is to assure that all routers has connected
1534 to the primary router. Affected file silcd/server_backup.c.
1536 * Changed the RNG to take the first IV from random data. It
1537 used to take it from zero actually. Changed the RNG also
1538 to use /dev/urandom during session. /dev/random is used
1539 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1541 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1543 * Changed the SILC packet header to have the first two bytes
1544 (the packet length) encrypted. Affected files aroung the
1545 code tree, lib/silccore/silcpacket.[ch]. Removed the
1546 SilcPacketCheckDecrypt callback. It is not needed anymore
1547 since the silc_packet_receive_process will determine now
1548 whether the packet is normal or special.
1550 * Implemented the unidirectional MAC keys. Affected files
1551 lib/silcske/silcske.c, silcd/protocol.c and
1552 lib/silcclient/protocol.c.
1554 * Implemented the packet sequence number to the MAC computation.
1555 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1556 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1557 lib/silcclient/protocol.c.
1559 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1561 * Allow backup router to announce servers. All servers
1562 announced by backup router are added to the global list
1563 automatically. Update hte server's socket to our primary
1564 router also when backup router announces a server.
1565 Affected file silcd/packet_receive.c.
1567 * Do not update the client->router in the function
1568 silc_server_udpate_clients_by_server if the client is on
1569 global list. We might fail to find any specific server
1570 for locally connected clients and local cell clients. They
1571 should still use the `from' and not `to' as client->router.
1572 This fixes backup router resuming protocol. Affected file
1573 silcd/server_util.c.
1575 * Decrease channel statistics count only if the channel
1576 deletion worked. Affected files are silcd/server.c and
1577 silcd/server_util.c.
1579 * Added silc_server_update_servers_by_server to update origin
1580 of all server entries. Used during backup router protocol.
1581 Affected files silcd/server_util.[ch], silcd/server.c. and
1582 silcd/backup_router.c.
1584 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1585 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1586 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1587 lib/silccrypt/silchmac.c.
1589 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1591 * Assure that router cannot reroute the same channel message
1592 to the sender. Affected file silcd/packet_receive.c.
1594 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1596 * Made better checks that the channel message is not sent
1597 to the router it came from. Affected file is
1598 silcd/packet_send.c. Fixed memory leak too.
1600 * Announce informations for incoming router connection, but
1601 only after checking if it is replaced by backup router.
1602 Affected file silcd/packet_receive.c.
1604 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1606 * Fixed the backup resuming protocol to work in multiple
1607 router environment. Affected file silcd/server_backup.c.
1609 * Route packet only to one router in the function
1610 silc_server_packet_send_to_channel. Affected file is
1611 silcd/packet_send.c.
1613 * Fixed silc_server_send_notify_dest to set the broadcast
1614 flag. Fixed the silc_server_send_notify_topic to actually
1615 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1616 Affected file silcd/packet_send.c.
1618 * Changed the SFTP Filesystem interface. Changed the
1619 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1620 the filesystem operation function. The SilcSFTPFilesystem
1621 is now a context that is allocated by all filesystem allocation
1622 functions and it already includes the operations structure
1623 and filesystem specific context. It is given as argument
1624 now to the silc_sftp_server_start. This made the interface
1625 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1626 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1628 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1630 * Changed the backup router adding and getting interfaces
1631 in the server. The router that will be replaced by the
1632 specified backup router is now sent as argument. Affected
1633 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1636 * Added silc_net_addr2bin_ne to return the binary form of
1637 the IP address in network byte order. Affected files
1638 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1640 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1642 * Check for existing server ID in silc_server_new_server
1643 and in silc_server_connect_to_router_final and remove the
1644 old entry if it exists. Affected file silcd/packet_receive.c,
1647 * Send the channel message always to only one router, either
1648 in upstream or downstream. Affected file is
1649 silcd/packet_send.c.
1651 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1653 * Wrote the definition of the backup resuming protocol to the
1654 protocol specification.
1656 * Removed one redundant channel key generation from normal
1657 server during joining procedure. Removed one redundant
1658 channel key sending from server to router during joining
1659 procedure. Affected file silcd/command.c.
1661 * Made minor bugfixes to the backup router resuming protocol.
1662 Affected file silcd/server_backup.c, server.c.
1664 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1666 * Added --disable-asm configuration option. Affected files
1667 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1670 * Implemented the backup resuming protocol that is used to
1671 resume the primary router position in the cell after the
1672 primary router comes back online. Affected files
1673 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1674 and silcd/server_util.[ch].
1676 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1678 * Sleep two (2) seconds after sending QUIT command to server.
1679 Affected file lib/silcclient/command.c.
1681 * Assure that if outgoing data buffer is pending do not force
1682 send any data. Affected file silcd/packet_send.c.
1684 * Assure that if outgoing data buffer is pending do not force
1685 send any data. Affected file lib/silcclient/client.c.
1687 * Implemented the backup router support when the primary router
1688 goes down. The servers and routers can now use the backup
1689 router as new primary router without loosing connectivity.
1691 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1693 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1694 in the server to indicate disabled entry. All data read
1695 from the connection will be ignored and no data is sent
1696 for entry that is disabled. Affected files are
1697 silcd/idlist.h, silcd/server.c.
1699 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1701 * Created SFTP client and server test programs in the
1702 lib/silcsftp/tests directory.
1704 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1706 * Implemented memory filesystem (virtual filesystem) for
1707 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1710 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1712 * Implemented the SFTP (SSH File Transfer Protocol) to the
1713 lib/silcsftp. It includes SFTP client and SFTP server
1716 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1718 * Moved lib/silccore/silcprotocol.[ch] to the
1719 lib/silcutil library.
1721 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1722 take variable argument list pointer as argument. Affected
1723 file lib/silcutil/silcbuffmt.[ch].
1725 * Added silc_buffer_set function that is used to set data
1726 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1727 Affected file lib/silcutil/silcbuffer.h.
1729 * Changed various routines in the core library to use the new
1730 silc_buffer_set instead of allocating new buffer only for
1733 * Added 64-bit value formatting and unformatting support to the
1734 silc_buffer_[un]format routines. Affected file is
1735 lib/silcutil/silcbuffmt.[ch].
1737 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1738 to includes/bitmove.h.
1740 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1742 * Fixed channel user mode saving in client library. Affected
1743 file lib/silcclient/command[_reply].c.
1745 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1747 * Defined the file transfer to the SILC Protocol. Added
1748 new packet type SILC_PACKET_FTP and defined File Transfer
1749 Payload. The mandatory file transfer protocol is SFTP
1750 (SSH File Transfer Protocol). Affected file in addition
1751 of the internet draft is lib/silccore/silcpacket.h.
1753 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1754 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1755 is used as part of backup router protocol when the primary
1756 router of the cell is back online and wishes to resume
1757 the position as primary router.
1759 * Redefined the MAC generation keys in the protocol. The
1760 same key is not used anymore in both direction. Both
1761 direction will now use different keys for sending and
1762 receiving. This fixes a potential security flaw. This
1763 change causes incompatibilities in the protocol.
1765 * Redefined also the MAC computation from the packet.
1766 An packet sequence number is now added to the MAC
1767 computation. This prevents possible replay attacks against
1768 the protocol. This change too causes incompatibilities
1771 Added `sequence' field to the SilcPacketContext to hold
1772 the current sequence number for the packet.
1774 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1776 * Added `created' field to the SilcIDListData in the file
1777 silcd/idlist.h to indicate the time when the entry was
1780 * Added `created' field to the SilcChannelEntry too. Affected
1781 file silcd/idlist.h.
1783 * Added `creation_time' aguments to all the announcement functions
1784 in the server. If it is provided then only the entries that
1785 was created after the provided time frame are actually
1786 announced. Affected file silcd/server.[ch].
1788 * The protocol says that the Channel ID's IP address must be
1789 based on the router's IP address. Added check for this in
1790 the silc_server_new_channel when processing incoming New Channel
1791 Payload. Affected file silcd/packet_receive.c.
1793 * Print out the correct version with --version in SILC client.
1794 Affected file irssi/src/silc/core/silc-core.c.
1796 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1798 * Fixed WHOWAS command to check for completnes of the client
1799 entry always, not just when the command is coming from client.
1800 Affected file silcd/command.c.
1802 * Added new function silc_server_packet_queue_purge to purge the
1803 outgoing data queue to the network. After the function returns
1804 it is guaranteed that the outgoing packet queue is empty.
1805 Affected file silcd/packet_send.[ch].
1807 * Purge the outgoing packet queue in the rekey protocol's final
1808 callback to assure that all rekey packets go to the network
1809 before quitting the protocol. Affected file silcd/server.c.
1811 * Added silc_client_packet_queue_parse as similar function as
1812 in server to the client library. The affected file is
1813 lib/silcclient/client.c.
1815 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1817 * Splitted silcd/server.c and created silcd/server_util.[ch]
1818 for utility functions.
1820 * Added new socket flag SILC_SF_DISABLED to indicate that the
1821 connection is open but nothing can be sent to or received from
1822 the connection. Affected file lib/silcutil/silsockconn.[ch].
1823 The checking for disabled socket is checked in the low level
1824 silc_socket_write and silc_socket_read functions.
1826 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1828 * Allow only nicknames and channel names that fits into the
1829 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1831 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1833 * When processing JOIN command reply in server check that if
1834 the channel exists in our global list we'll move it the local
1835 list. Affected file silcd/command_reply.c.
1837 * Fixed the check whether client is joined on the channel already
1838 in JOIN command. Affected file lib/silcclient/command.c.
1840 * Fixed the JOIN command reply to check whether the channel
1841 already exists. Affected file lib/silcclient/command_reply.c.
1843 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1845 * Added silc_ske_status_string to map the SKE error numbers
1846 to readable strings. The affected files are
1847 lib/silcske/silcske[_status].[ch].
1849 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1851 * Do not show the private channels on the WHOIS channel list
1852 as it is not allowed by the protocol. The affected file is
1855 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1857 * Assure that the packet length digged from the actual packet
1858 is something sensible in the silc_packet_decrypt_rest_special
1859 in lib/silccrypt/silcpacket.c.
1861 * Free and NULL the allocated pointer in silc_hmac_alloc if
1862 the HMAC allocation fails. The affected file is
1863 lib/silccrypt/silchmac.c.
1865 * Print the selected security properties to the log files in
1866 the server. Affected file silcd/protocol.c.
1868 * Add SKE's reference counter even if calling the completion
1869 callback manually. Otherwise it goes negative, although it
1870 does not cause any problems. The affected file is
1871 lib/silcske/silcske.c.
1873 * Remove the client entry with short timeout after giving the
1874 KILL command. Affected file lib/silcclient/command.c.
1876 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1877 case all found clients are already disconnected (WHOWAS would
1878 found them) in the server. Affected file silcd/command.c.
1880 * Update the last_receive (time of last data received) to be
1881 updated only when received private or channel message so that
1882 the idle time showed in WHOIS makes more sense.
1884 * Added boolean field `valid' in to the SilcClientEntry in the
1885 client library to indicate whether the entry is valid or not.
1886 This fixes the nickname change bug on channel when changing
1887 the nickname to be same than the old (like nick to Nick) the
1888 nickname formatter doesn't set the new nick anymore to Nick@host.
1889 Affected file lib/silcclient/idlist.[ch].
1891 * Now actually fixed the nickname changing on disconnection.
1892 Added new function silc_change_nick to the Irssi SILC Client.
1893 Affected file irssi/src/silc/core/client_ops.c,
1894 irssi/src/silc/core/silc-nicklist.[ch].
1896 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1898 * Check that the public key exists in the GETKEY command before
1899 trying to encode it. Affected file silcd/command.c.
1901 * Print some notifications on received public keys with GETKEY
1902 command in the Irssi SILC Client. Affected files are
1903 irssi/src/fe-common/silc/module-formats.[ch],
1904 irssi/src/silc/core/client_ops.c.
1906 * Use IDENTIFY command to resolve the server information in the
1907 GETKEY command instead of INFO command. Affected file
1908 lib/silcclient/command.c.
1910 * All command reply functions in the client library now calls
1911 the pending command reply callbacks even if an error has
1912 occurred. The server has done this a long time and now it was
1913 time to move the client library to this as well. Now all
1914 errors can be delivered back to the pending command reply
1915 callbacks if necessary. Affected files are
1916 lib/silcclient/command[_reply].[ch].
1918 * Change the nickname on disconnection back to the username
1919 because in reconnect the server will enforce it to it anyway.
1920 Affected file irssi/src/silc/core/silc-servers.c.
1922 * Fixed a config file parsing bug in the Irssi SILC client.
1923 Affected file irssi/src/silc/core/clientconfig.c.
1925 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1927 * When printing the channel mode on JOIN, verify that the
1928 channel key and channel's HMAC are valid. Affected file
1929 irssi/src/silc/core/client_ops.c.
1931 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1933 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1934 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1935 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1937 * Removed channel key rekey task deleting from the function
1938 silc_server_save_channel_key. Affected file silcd/server.c.
1939 Added explicit timeout task context instead that is used to
1940 delete the task if we are registering a new task before the
1941 new task has elapsed.
1943 * When channel key rekey occurs the client library now saves
1944 the old channel key for a short period of time (10 seconds) and
1945 is able to use it in case some is still sending channel
1946 messages encrypted with the old key after the rekey. Affected
1947 file lib/silcclient/[idlist.h|client_channel.c].
1949 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1951 * Added check to the silc_server_new_id_real to not accept
1952 new ID if it is the sender's own ID. Affected file is
1953 silcd/packet_receive.c.
1955 * Assure that we do not announce ourself or the one we've
1956 sending our announcements when we're router and are announcing
1957 servers to our primary router. Affected file silcd/server.c.
1959 * Fixed silc_server_command_identify_check_client to assemble
1960 correct WHOIS packet. It send corrupted WHOIS packet and
1961 caused problem with router to router connections. Affected
1962 file silcd/command.c.
1964 Fixed also silc_server_command_whois_check the same way
1965 as for the IDENTIFY command.
1967 * Added new SilcIDListStatus to the server in the SilcIDListData
1968 structure. The status now includes the current status of
1969 the entry (like registered, resolved etc.). Affected file
1970 silcd/idlist.[ch]. Defined a bunch of different status types
1971 as well. This replaced the old boolean registered field as well.
1973 Added resolve_cmd_ident field to the SilcClientEntry structure
1974 too so that if the entry is for example being resolved so
1975 another command may attach to the same pending command reply
1976 without requiring to resolve the same entry again. This concept
1977 should optimize the WHOIS and the IDENTIFY resolving under
1978 heavy load by taking away unnecessary resolving for entries
1979 that are being resolved already.
1981 Added support for adding multiple pending commands for one
1982 command idenfier. Affected file silcd/command[_reply].[ch].
1984 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1985 before deleting the data. Otherwise the hash table will have
1986 freed data in comparison functions. Affected file is
1987 silcd/command_reply.c.
1989 * Fixed silc_idlist_replace_client_id to add the new entry to
1990 the cache with NULL nickname. Otherwise there will be invalid
1991 memory as the nickname after the nickname is freed. Affected
1992 file silcd/packet_receive.c.
1994 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1995 saved into wrong slots because the previous number of entries
1996 was not taken into account. Affected file silcd/idlist.c.
1997 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1999 * If we are router and we receive JOIN notify to a channel that
2000 does not have any users then notified client is marked as the
2001 channel founder, as it is it. The affected file is
2002 silcd/packet_receive.c
2004 * Added to the extended hash table API's table_del_*ext functions
2005 the destructor as argument too, so that the caller can decide
2006 which destructor to use or whether to use destructor at all.
2007 Affected file lib/silcutil/silchashtable.[ch].
2009 * Fixed ID Cache purging. It actually deleted the entries from
2010 the hash table after the data was freed. The hash table ended
2011 up comparing freed memory. The affected file is
2012 lib/silccore/silcidcache.c.
2014 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2016 * Fixed Irssi SILC client's KILL command's HELP syntax.
2018 * The USERS command now resolves the detailed user information
2019 if the userinfo field is missing. Affected file is
2020 lib/silcclient/command_reply.c.
2022 * Do not print error in silc_file_read if the read file does
2023 not exist. Just silently return NULL. Affected file is
2024 lib/silcutil/silcutil.c.
2026 * Fixed the silc_log_output to not wine about NULL filename
2027 and to not create some bogus " " filename. Affected file is
2028 lib/silcutil/silclog.c.
2030 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2032 * Fixed various printing bugs on the user interface in the
2033 Irssi SILC Client. Minor changes that were forgotten from
2036 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2038 * Fixed the configure.in.pre and the compilation and distribution
2039 environment to support the new autoconf 2.52. That version is
2040 now required to compile the CVS trunk.
2042 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2044 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2045 to generally parse user@fqdn format strings. Affected file
2046 lib/silcutil/silcutil.c.
2048 * Added nickname_format and nickname_force_format fields to the
2049 SilcClientParams structure. The first one defines the format
2050 for the nicknames that the library will enforce if the receives
2051 multiple same nicknames. The second one is boolean value and
2052 can be used to force the library to always enforce the format
2053 to the nicknames regardles whether there are multiple nicknames
2054 or not. This configurable formatting was employed to flexibly
2055 support accessing multiple nicknames from the user interface.
2056 The userinterface can now set the nicknames to what ever format
2057 they prefer. Affected file lib/silcclient/silcapi.h.
2059 Added function silc_client_nickname_format to the file
2060 lib/silcclient/idlist.c. It performs the nickname formatting.
2062 Added new field `hostname´ to the SilcClientEntry context.
2063 It holds the hostname of the client. Affected file is
2064 lib/silcclient/idlist.h.
2066 * Irssi SILC Client sets the nicknames in nick@hostn format.
2067 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2068 irssi/src/silc/core/silc-core.c.
2070 The WHOIS printing now also shows both the real nickname and
2071 the formatted nickname so that user knows how to access the
2072 user if there are multiple same nicknames cached. Affected
2073 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2074 printing formatting too to take the hostname now as a separate
2075 argument. The Affected file is
2076 irssi/src/fe-common/silc/modules-formats.[ch].
2078 * Changed the silc_client_get_clients_local to accept the formatted
2079 nickname as argument. It accepts the real nickname too but the
2080 formatted nickname can be used to find the true entry from
2081 multiple entries. Affected file lib/silcclient/silcapi.h and
2082 lib/silcclient/idlist.c.
2084 * Added nickname_format_parse field to the SilcClientParams.
2085 It is a callback function provided by the application to parse
2086 the nickname out of the formatted nickname string. The library
2087 calls it to get the nickname from the formatted string. Since
2088 the application generally knows better the format of the nickname
2089 string it parses it instead of the library, even though library
2090 encodes the formatted string. If the callback function is not
2091 provided then the library will use the string as is. The
2092 affected file is lib/silcclient/silcapi.h.
2094 * All the nickname strings passed to the client library in
2095 commands are now expected to be formatted nickname strings.
2096 If the command does not support the formatted nickname string
2097 it will assume that the sent string is the actual nickname.
2098 Affected file lib/silcclient/command.c.
2100 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2102 * Added public key authentication support to OPER and SILCOPER
2103 commands in the client library. Affected file is
2104 lib/silcclient/command.c.
2106 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2108 * Changed the get_auth_methdod client operation to be asynchronous.
2109 It can be async if the application resolves the authentication
2110 method from the server during the negotiation. Added new
2111 SilcGetAuthMeth completion callback that the application will
2112 call after resolving the authentication method.
2114 Added function silc_client_request_authentication_method that
2115 the application can use to resolve the authentication method
2116 from the server. Added also SilcConnectionAuthRequest callback
2117 that the library will call after the server has replied. The
2118 application can call this function if it does not know the
2119 current authentication method.
2121 Affected files are lib/silcclient/client.c and
2122 lib/silcclient/silcapi.h.
2124 * The Irssi SILC client now automatically resolves the authentication
2125 method incase any configuration information is not present (and
2126 currently there never is). The affected file is
2127 irssi/src/silc/core/client_ops.c.
2129 * Fixed public key authentication from the client library.
2130 Affected file lib/silcclient/protocol.c. Changed also the
2131 protocol specification about the public key authentication in
2132 the connection authentication protocol. The actual data to be
2133 signed is now computed with a hash function before signing.
2135 * Fixed the public key authentication from the server as well.
2136 Affected file silcd/protocol.c.
2138 * Removed the mlock()'s from the memory allocation routines.
2139 Affected file lib/silcutil/silcmemory.c. The ./configure does
2140 not check anymore for the mlock(). Affected file is
2143 * Fixed USERS command in server to allow the execution of the
2144 command for private and secret channels if the client sending
2145 the command is on the channel. Affected file silcd/command.c.
2147 * Fixed silc_client_get_clients_local to return the clients
2148 count correctly. It could return wrong value. Affected file
2149 lib/silcclient/idlist.c.
2151 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2153 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2154 types. The assembler optimizations seemed not to like 64-bit
2155 data types. The assmebler optimizations thus are now enabled
2156 also for BSD systems as opposed to only enable them for Linux.
2158 * Do not check for threads at all on BSD systems. Affected
2159 file configure.in.pre.
2161 * Removed -n and -h options from the Irssi SILC Client since
2162 they are not used in silc.
2164 * Fixed the prime generation to assure that the first digit
2165 of the generated random number is not zero since our conversion
2166 routines does not like number strings that starts with zero
2167 digit. If zero digit is seen the random number is regenerated.
2168 This caused some corrupted RSA keys when the zero first digit
2169 was met. Affected file lib/silcmath/silcprimegen.c.
2171 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2173 * Fixed WIN32 configuration in the ./configure script.
2174 Fixed to include xti.h on environments that has it.
2175 Patches by Carsten Ilchmann and andrew.
2177 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2179 * Changed the silc_id_create_client_id to be collision
2180 resistant. It is now assured that there cannot be created
2181 two same client ID's. I suspect that some weird bugs in
2182 the server were actually caused by duplicate Client IDs.
2183 Affected file silcd/serverid.[ch]. A router receiving
2184 new ID now also assures and informs the sending server
2185 if the ID caused collision.
2187 * Changed the silc_id_create_channel_id to also assure that
2188 there are no collisions.
2190 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2192 * Statement about ignoring the Mutual Authentication flag when
2193 performing rekey with PFS was a bit misleading. It is ignored
2194 if it was set in the initial negotiation, it cannot be even
2195 set in the rekey. Fixed in the ke-auth draft. Started the
2196 new versions of the protocol drafts in the doc/.
2198 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2200 * Fixed a bug in silc_client_command_identify_save when saving
2201 new channel information. The channel name was no duplicated
2202 and caused crash on exit. Affected file is
2203 lib/silcclient/command_reply.c.
2205 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2207 * Fixed the getkey command handling in the server. Send just
2208 empty OK reply to the sender if the key could not be fetched
2209 (but everything else was ok, like the key just was not available).
2210 Changed the public key parameter to optional in the protocol
2211 specs so that empty OK reply can be sent. Affected file
2214 Added a message to Irssi SILC client to tell to user if the
2215 server did not return a public key.
2217 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2219 * Fixed a channel key regeneration bug. It registered new
2220 timeout tasks exponentially until all system resources were
2221 used. Affected file silcd/server.c.
2223 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2225 * Added the SILC Document generator to the scripts/silcdoc.
2226 It can be used to generate the Toolkit Reference Manual out
2227 of the source tree. Internally it will also use the RoboDoc
2228 generator now imported in util/robodoc.
2230 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2232 * Added couple of return's in rekey protocol if error orccurred
2233 during the protocol. The execution must be terminated.
2234 Affected file silcd/protocol.c. Also, terminate the protocol
2235 always with timeout.
2237 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2239 * The client's Client ID was created initally from the wrong
2240 nickname (it could have been in format nick@host) in the
2241 silc_server_new_client. Affected file silcd/packet_receive.c
2243 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2245 * Added some SILC_LOG_ERROR's to various error conditions
2246 if client could not be added to ID cache. Affected files
2247 silcd/packet_receive.c and silcd/server.c.
2249 * When client's sock->user_data is freed, NULL also the
2250 client->router and client->connection pointers. Added check
2251 for these pointers being NULL to various places around the
2252 code. Affected file silcd/server.c.
2254 * Added client->data.registered == TRUE checks to various
2255 places around the code to assure that unregistered client's
2256 are not handled when it is not allowed. Affected file
2259 * Added `bool registered' fields to all
2260 silc_idlist_[server|client]_get_* routines to indicate whether
2261 the fetched client needs to be registered or not. Affected
2262 file silcd/idlist.[ch].
2264 * Add your own entry as registered to the ID cache in the
2265 server. Affected file server.c.
2267 * Fixed a bug in silc_server_new_server. The SilcServer was
2268 set as the new server's context instead of SilcServerEntry.
2269 This naturally caused some weird bugs.
2271 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2273 * Do not delete the channel rekey task when adding it
2274 for in silc_server_create_channel_key.
2276 * Changed the silc_server_create_channel_key to return
2277 TRUE or FALSE to indicate the success of the channel key
2280 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2282 * Fixed MSVC++ project files and added missing files to
2283 Makefiles under win32/.
2285 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2287 * Do not add TCP_NODELAY flag if the operating system
2288 does not have it defined. Affected files are
2289 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2291 * Fixed buffer overflow from Irssi SILC Client. Affected
2292 file irssi/src/fe-common/core/themes.c.
2294 * Fixed double free in client library in the file
2295 lib/silcclient/client.c when disconnecting from server.
2297 * Applied double free patch from cras to Irssi SILC client.
2298 Affected files irssi/src/core/[modules/expandos].c
2300 * Fixed the disconnection handling to Irssi SILC Client.
2301 The application must call silc_client_close_connection
2302 in ops->connect client operation in case of failure of
2303 the connection. Affected file is
2304 irssi/src/silc/core/client_ops.c.
2306 * Do not set sock->protocol to NULL in the function
2307 silc_client_close_connection after executing the protocol's
2308 final callback since the sock might not be valid anymore.
2309 Affected file lib/silcclient/client.c.
2311 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2313 * Do not enable SILC_THREADS if the linking with libpthread
2314 did not happen. Affected file configure.in.pre.
2316 * Added notion to protocol specification that server must
2317 verify the sent authentication payload with CMODE when
2318 setting the channel founder key. Implemented it to the
2319 server. Affected file silcd/command.c.
2321 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2323 * Added _EXTRA_DIST SILC distribution variable to the
2324 distributions file. It is used to conditionally add extra
2325 files or directories to the specific distribution. Affected
2326 files ./prepare, Makefile.am.pre and distributions.
2328 Removed the `_' from the start of the distribution names.
2331 * Added README.WIN32 for instructions to compile the Toolkit
2334 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2336 * Fixed a double free in disconnection in the server. Affected
2337 file is silcd/server.c.
2339 * Fixed the lib/silcske/groups.c to work now also with GMP
2340 MP library. The string conversion did not work when using
2341 specific base and the base is indicated in the string as well.
2343 * Created win32/ directory which now includes MSVC++ specific
2344 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2345 It will appear only in the toolkit distribution
2347 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2349 * Changed the key material distribution function in case when
2350 the hash output is too short. The data is now concatenated
2351 a bit differently than it used to. Made the change to the
2352 SKE protocol specification.
2354 * Added better GMP detection to configure.in.pre. A patch
2357 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2359 * Fixed a minor bug in SKE that might cause some problem on
2360 some platforms. Affected file lib/silcske/silcske.c.
2362 * Added the cookie checking for initiator in the SKE. It checks
2363 that the responder returns the sent cookie unmodified. The
2364 affected file is lib/silcske/silcske.c. Added new SKE
2365 error type INVALID_COOKIE that can be sent during the
2366 negotiation. Fixed some memory leaks as well.
2368 * Added the "invalid cookie" error message to Irssi SILC client's
2371 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2373 * Added `task_max' field to the SilcClientParams to indicate
2374 the maximum tasks the scheduler can handle. If set to zero,
2375 default values are used. Affected file lib/silcclient/silcapi.h.
2377 * Fixed memory leaks in silc_client_close_connection. Affected
2378 file lib/silcclient/client.c.
2380 * Added silc_client_del_client_entry to client library to free
2381 all memory of given client entry. Affected file is
2382 lib/silcclient/idlist.[ch].
2384 * Added new functions silc_client_del_channel and
2385 silc_client_del_server to delete channel and server entries.
2386 Affected file lib/silcclient/[silcapi.h/idlist.c].
2388 * Removed silc_client_del_client_by_id from silcapi.h.
2390 * Fixed the INFO command to return the server's own info
2391 correctly when querying by Server ID. Affected file is
2394 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2396 * Removed the non-blocking settings in WIN32 code in the
2397 silc_sock_[read/write] and added SleepEx instead. Affected
2398 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2399 of input data is now checked with FIONREAD and ioctlsocket.
2401 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2403 * Call silc_schedule_task_del_by_context in the
2404 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2405 Affected file lib/silccore/silcprotocol.c.
2407 * Call silc_protocol_cancel for active protocols in the
2408 silc_server_close_connection if the funtion
2409 silc_server_free_sock_user_data has not been called.
2410 Affected file silcd/server.c.
2412 * Generic tasks cannot be deleted using the del_by_fd
2413 task deleting function since generic tasks does not match
2414 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2416 * Added a notion to SILCOPER help file that the SILCOPER works
2417 only on router server, not on normal server.
2419 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2421 * Added for WIN32 support for the new scheduler as well.
2422 Affected file lib/silcutil/win32/silcwin32schedule.c.
2424 * Fixed the SHA1 implementation to work on various platforms.
2426 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2428 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2429 API. It is part of the scheduler now. Everything else is
2430 as previously but some functions has changed their names.
2431 Checkout the lib/silcutil/silcschedule.h for the interface.
2432 Updated all applications to use the new interface. Affected
2433 files are lib/silcutil/silcschedule.[ch].
2435 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2437 * Found a bug in the SKE implementation. The HASH value,
2438 specified by the protocol, was not computed correctly. The
2439 public key of the responder was not added to the computation
2440 even though it is mandatory. Affected file lib/silcske/silcske.c.
2441 This unfortunately causes incompatibilities with older
2442 clients and servers.
2444 * Added WIN32 specific network init and uninit functions:
2445 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2446 the Winsock2. Affected file lib/silcutil/silcnet.h and
2447 lib/silcutil/win32/silcwin32net.c.
2449 * Set the socket always to nonblocking mode on WIN32 after
2450 reading data or writing data. Affected file is
2451 lib/silcutil/win32/silcwin32sockconn.c.
2453 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * Fixed various compilation problems under WIN32. Affected
2456 files lib/silcutil/win32/silcwin32thread.c and
2457 lib/silcutil/win32/silcwin32schedule.c.
2459 * Removed all _internal.h #includes from public header
2460 files. Internal headers must never be included from
2463 Removed also the lib/silcske/payload_internal.h file.
2465 * All include files that may be needed (public and some others
2466 included by the public headers) by application developers are
2467 now copied to the ./includes directory. It does not copy any
2468 internal headers. Affected file Makefile.defines.pre and all
2469 Makefile.am's under lib/ and subdirs.
2471 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2473 * Do not change the ~/.silc directory's permissions automatically.
2474 Affected file irssi/src/silc/core/clientutil.c.
2476 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2478 * Do not cancel the protocol in silc_server_close_connection
2479 it might cause recursion. Now cancelled in the function
2480 silc_server_free_sock_user_data. Affected file silcd/server.c.
2482 * Fixed the silc_server_remove_clients_by_server to regenerate
2483 the channel keys correctly finally. Added also new function
2484 silc_server_remove_clients_channels to actually do it.
2485 Affected file silcd/server.c.
2487 * Fixed the silc_server_new_channel to not crash by giving
2488 wrong router to the new channel. Affected file is
2489 silcd/packet_receive.c.
2491 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2493 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2494 which is given as argument to the silc_client_alloc now.
2495 It can be used to configure the client and set various parameters
2496 that affect the function of the client.
2498 * The USERS command in server did not check whether the channel
2499 is private or secret. Affected file silcd/command.c.
2501 * Added new argument to the USERS command in protocol specification.
2502 The USERS command now can take the channel name as argument
2503 as well. Added support for this in client and server and
2504 updated the protocol specs.
2506 * Completed the GETKEY command in client. It can be now used
2507 to fetch also servers public key not only some clients.
2508 Affected files lib/silcclient/command[_reply].c.
2510 * Added silc_client_get_server to return server entry by the
2511 server name. Affected files lib/silcclient/silcapi.h and
2514 * Redefined the IDENTIFY command in protocol specification to be
2515 more generic. It now can be used to query information about
2516 any entity in the SILC Network, including clients, servers and
2517 channels. The query may be based either the entity's name
2518 or the ID. Added support for this in both client and server.
2520 Affected files silcd/command.c and lib/silcclient/command.c
2521 and command_reply.c.
2523 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2524 the _from_client and _from_server functions. Affected file
2527 * Added silc_client_get_channel_by_id_resolve to the file
2528 lib/silcclient/silcapi.h to resolve channel information by
2529 its ID. Added also silc_client_get_channel_by_id that
2530 does not resolve it from the server.
2532 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2534 * Added SilcServerEntry context into the client library
2535 to represent one server. The INFO command now allocates
2536 these to save the resolved server info. For now on the
2537 client library will also keep information about servers,
2538 connected and resolved with INFO.
2540 The INFO command now allocates the SilcServerEntry context
2541 and saves the server info there. The COMMAND_REPLY in
2542 the INFO now returns the parameters to application in
2543 same order as defined in the protocol specification.
2545 The entries are cached in the client->server_cache.
2547 * The INFO command is now issued after received the Client ID
2548 from the server. Affected file lib/silcclient/client.c.
2550 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2551 to the application as the mode changer might be server.
2552 It is guaranteed that NULL is not returned anymore to the
2553 application. Affected file lib/silcclient/client_notify.c.
2555 The ID Type is now also passed to the application so that
2556 it can check whether the returned entry is SilcClientEntry
2559 Added new function silc_client_get_server_by_id to return
2560 the server entry by ID. Affected files are the
2561 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2563 * Do not create the channel in the Irssi SILC Client when issuing
2564 the JOIN command but when received the sucessful JOIN command
2565 reply. Otherwise the channel might get created even though we
2566 could not join it. The Affected file is
2567 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2569 * Fixed a channel joining bug in router. The router must also
2570 check the channel modes, invite and ban lists etc. when serving
2571 the JOIN command sent by normal server. Affected file is
2572 silcd/command.c. The router now resolves the client's
2573 information from the server who sent the JOIN command if it
2574 does not know it, and processes the JOIN command only after
2577 * Changed the SilcCommandCb to take new argument; void *context2.
2578 Affected file lib/silccore/silccommand.h
2580 The second argument in the command callbacks in the server now
2581 includes the SilcServerCommandReplyContext if the command was
2582 called as pending command callback from the command reply.
2583 Otherwise it is NULL. When called as pending the status of the
2584 command reply will be checked and if it was erronous the
2585 error will be sent to the original sender of the command.
2586 This way the client always receives the error messages even
2587 though the server was actually the one who received the error
2588 when it resent the command to router, for example. Affected
2589 files silcd/command[_reply].[ch].
2591 * Fixed sending WHOWAS command's error message to client if
2592 the requested client could not be found. It was missing.
2595 * Changed the CMODE and CUMODE commands reply arguments in the
2596 protocol specification. The Channel ID is now sent in both
2597 of the commands to identify the channel. Implemented this
2598 new feature to the client and server. Affected files
2599 lib/silcclient/command_reply.c and silcd/command.c.
2601 * Made better checks for invite and ban lists in the JOIN
2602 command in server. Affected file silcd/command.c.
2604 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2606 * The server now performs the incoming host IP/DNS lookup
2607 using the silc_socket_host_lookup and thus does not block
2608 the server anymore. Affected file silcd/server.c.
2610 * Completed the multi-thread support for SILC Scheduler in
2611 the lib/silcutil/silcschedule.c.
2613 * Fixed the configure.in.pre to detect the pthread correctly
2616 * Fixed a deadlock in silc_task_queue_wakeup in the file
2617 lib/silcutil/silctask.c.
2619 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2621 * Added new function silc_schedule_wakeup that is used in
2622 multi-threaded environment to wakeup the main thread's
2623 schduler. It needs to be used when a thread adds a new task
2624 or removes a task from task queues. After waking up, the
2625 scheduler will detect the task queue changes. If threads
2626 support is not compiled in this function has no effect.
2627 Implemented the wakeup mechanism to both Unix and WIN32
2628 systems. Affected files are lib/silcutil/silcschedule.[ch],
2629 lib/silcutil/unix/silcunixschedule.c and the
2630 lib/silcutil/win32/silcwin32schedule.c.
2632 * Added new function silc_task_queue_wakeup to wakeup the
2633 scheduler by the specified task queue. Affected file
2634 lib/silcutil/silctask.[ch].
2636 * The silc_socket_host_lookup_start now wakes up the scheduler
2637 after adding the timeout task. Affected file is
2638 lib/silcutil/silcsockconn.c.
2640 * The silc_socket_host_lookup is synchronous now if the threads
2641 support is not compiled in. However, the callback is still
2642 called asyncronously through the scheduler, anyway. Affected
2643 file lib/silcutil/silcsockconn.c.
2645 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2647 * Added new function silc_socket_host_lookup to perform
2648 asynchronous IP and FQDN lookups for the socket connection.
2649 Affected files lib/silcutil/silcsockconn.[ch].
2651 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2653 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2654 that may or may not compile the mutex support in.
2656 Changed the silc_mutex_alloc interface. It allocates the
2657 mutex now to the sent pointer and returns TRUE or FALSE.
2659 Affected file lib/silcutil/silcmutex.h.
2661 * Wrote the SILC Task Queue interface to support multi-threads.
2662 Affected file lib/silcutil/silctask.[ch].
2664 * Wrote the SILC Scheduler to support multi-threads. Affected
2665 file lib/silcutil/silcschedule.c.
2667 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2669 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2670 in lib/silcutil/win32/.
2672 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2674 * Defined SILC Mutex API and SILC Thread API and implemented
2675 them for Unix. Affected files are
2676 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2677 lib/silcutil/unix/silcunixmutex.c and
2678 lib/silcutil/unix/silcunixthread.c.
2680 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2682 * Fixed the silc_server_remove_clients_by_server's channel
2683 key re-generation. The hash table handling was incorrect
2684 and would not work with many channels. Affected file is
2687 * Fixed some memory leaks around the server code.
2689 * Rewrote the silc_server_get_users_on_channel to support IPv6
2690 based Client ID's. Affected file silcd/server.c.
2692 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2693 specification. However, a separate document must be written
2694 to define the detailed signing procedure and the payload
2695 associated with the flag. Defined the flag to the
2696 lib/silccore/silcchannel.h as well.
2698 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2700 * Changed the dynamic tables to static size tables in the
2701 lib/silccrypt/silchmac.c.
2703 * Removed GCC dependencies from the code. A patch by cras.
2705 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2707 * Do not show the error "Error receiving packet bla bla"
2708 in server if it really was not an error (-2 means that reading
2709 is pending). Affected file silcd/server.c.
2711 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2713 * Fixed a possible crash in silc_server_remove_clients_by_server
2714 in silcd/server.c. Fixed there also some memory leaks.
2716 * Fixed the silc_idlist_replace_client_id. It could replace
2717 wrong key in the hash table. Affected file silcd/idlist.c.
2719 * Do not check whether there are global users on the channel
2720 if the channel->global_users is FALSE. Affected functions
2721 silc_server_remove_from_one_channel and
2722 silc_server_remove_from_channels in silcd/server.c. Also,
2723 do not check if the removed client is local as we can be
2724 sure that global client was not removed from the channel
2725 and checking for global users is not needed.
2727 * The silc_server_remove_clients_by_server now re-generates
2728 the channel keys correctly for those channels that had
2729 clients removed from them. Affected file silcd/server.c.
2731 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2733 * Found the reason of random crashes in the server. We weren't
2734 ignoring the SIGPIPE signal (which can be sent in write())
2735 and it crashed the server. Affected file silcd/silcd.c.
2737 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2739 * Assure that sock->user_data is not NULL in the function
2740 silc_server_packet_send in silcd/packet_send.c.
2742 * Disconnect the remote connection if it could not be added
2743 to any ID lists in the server. The affected file is
2746 * Check in silc_server_packet_send[_real/dest] that the
2747 socket is not disconnecting and ignore the data if it is.
2748 Affected file silcd/packet_send.c.
2750 * Define inline to __inline on native WIN32 compilation.
2751 Affected file includes/silcwin32.h.
2753 * Added some explicit type casts for inline code since MSVC
2754 require them. Affected files lib/silcutil/silcbuffer.h,
2755 lib/trq/silcdlist.h and lib/trq/silclist.h.
2757 * Print warning in log files from now on if the packet
2758 decryption fails. Affected file silcd/server.c.
2760 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2762 * Changed the `say' client operation's interface to accept
2763 new `type' argument to indicate the type of the message sent
2764 by the library. The application may filter the library's
2765 messages according the type. The affected file is the
2766 lib/silcclient/silcapi.h.
2768 * Added two new functions to lib/silcclient/silcapi.h:
2769 silc_client_del_client and silc_client_del_client_by_id.
2770 Affected file lib/silcclient/idlist.c.
2772 * Moved the clientincludes.h from includes/ to silc/ and
2773 serverincludes.h from includes/ to silcd/.
2775 * The modes for the CMODE and CUMODE are now passed as
2776 uint32 for application with COMMAND_REPLY. The affected
2777 file is lib/silcclient/command_reply.c.
2779 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2781 * /WHOIS without arguments shows client's own information.
2782 Affected file lib/silcclient/command.c.
2784 * Changed PING to not accept any arguments. The specs
2785 says that client can ping only the connected server so
2786 requiring an argument is not needed. Affected file is
2787 lib/silcclient/command.c.
2789 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2791 * Fixed a fatal bug in private message sending and reception
2792 encryption and decryption when using private message keys.
2793 The implementation was incorrect and did not follow the
2794 specification. It causd that some of the message were
2795 lost since it did not use the sending and receiving keys
2796 as the protocol suggests. This has been fixed and will cause
2797 incompatibilities with older clients when sending private
2798 message encrypted with private message keys. Affected files
2799 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2800 and various other in Irssi SILC Client.
2802 Added `responder' boolean argument to the functions
2803 silc_client_add_private_message_key[_ske] to indicate when
2804 the key is added as responder or initiator of the key
2807 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2809 * Removed the silc_ske_check_version function and created
2810 a SilcSKECheckVersion callback. Added also a function
2811 silc_ske_set_callbacks that is now used to set all SKE
2812 callbacks. The callback functions are not given to
2813 the SKE functions anymore, but this function is used to
2816 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2818 * Added `silc_version' argument to the silc_client_alloc
2819 to define the version of the application for the library.
2820 The library will use the version string to compare it
2821 against the remote host's (usually a server) version
2822 string. Affected file lib/silcclient/silcapi.h
2824 * Added the KE protocol context to Key Agreement context
2825 in client library so that we can abort the SKE if it
2826 is in process when we get timeout. Affected file is
2827 lib/silcclient/client_keyagr.c.
2829 * Do not resolve the client ID forever if it returns in the
2830 first time that such client does not exist. This was done
2831 for example with private message. Affected file is
2832 lib/silcclient/client_prvmsg.c.
2834 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2836 * Do not add regex.h for WIN32. The affected file
2837 includes/silcincludes.h.
2839 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2840 not work yet 100%. It generates the DLL's automatically
2841 when compiling with --with-win32 under cygwin.
2843 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2845 * lib/contrib/regex.c is not compiled on WIN32.
2847 * Added silc_net_get_socket_opt function to the
2848 lib/silcutil/silcnet.h.
2850 * Added includes/silcwin32.h for WIN32 specific includes
2853 * Do not use ptime structure or any of the posix process
2854 functions on WIN32 in lib/silccrypt/silrng.c.
2856 * Added silc_gettimeofday to provide generic function
2857 for struct timeval on all platforms. Added the function
2858 to lib/silcutil/silcutil.h.
2860 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2862 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2863 library as they clearly belong there. As a plus side we
2864 can make the actual socket connection routines platform
2867 Added also new generic function silc_socket_read and
2868 silc_socket_write (that used to be silc_packet_[read/write].
2869 The implementation of these are platform specific.
2871 * Added WIN32 specific routines of silc_socket_[read/write]
2872 to lib/silcutil/win32/silcwin32sockconn.c.
2874 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2876 * Added preliminary support for native WIN32 compilation under
2877 cygwin (using the -mno-cygwin option for GCC) to the
2878 ./configure.in.pre. The --with-win32 now prepares the
2879 compilation for native WIN32.
2881 * Rewrote the SILC Scheduler interface in the file
2882 lib/silcutil/silcschedule.h. The scheduler is now context
2883 based and does not have anymore any global static scheduler.
2884 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2885 and created lib/silcutil/win32 directory for WIN32 based
2888 * Added Unix specific network routines to the
2889 lib/silcutil/unix/silcunixnet.c and the old
2890 lib/silcutil/silcnet.c includes now only generic routines.
2892 Added WIN32 specific network routines to the
2893 lib/silcutil/win32/silcwin32net.c.
2895 * Added Unix specific utility functions from the
2896 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2898 * Added WIN32 SILC Scheduler to the file
2899 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2902 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2904 * Do not handle JOIN notify in the server if the target client
2905 is not registered (idata->registered == FALSE). The affected
2906 file is silcd/packet_receive.c.
2908 * Update the nickrec->founder in event_cumode in the Irssi SILC
2909 client. Affected file irssi/src/silc/core/silc-channels.c.
2911 * Fixed the CUMODE_CHANGE notify handling in the server when
2912 server and router are announcing their clients on channels.
2913 Now the mode changes are saved and notified correctly. The
2914 affected file is /silcd/packet_receive.c.
2916 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2917 They really did not replace the cache entry in the ID Cache.
2918 Now they do that. Affected file silcd/idlist.c.
2920 * Fixed the KICK notify handling in the Irssi SILC client to
2921 update the channel records so that the kicked client does not
2922 appear to be on the channel. The affected file is
2923 irssi/src/silc/core/silc-channels.c.
2925 * Always update the conn->current_channel when executing command
2926 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2928 * Fixed the KILL notify handling in Irssi SILC client to remove
2929 the killed client on all channels.
2931 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2933 * Fixed the silc_parse_command_line to remove extra spaces
2934 from the start and end of the arguments. Affected file is
2935 lib/silcutil/silcutil.c.
2937 * Cancel and free any active protocol in the function
2938 silc_server_close_connection. Affected file silcd/server.c.
2940 * Cancel and free any active protocol in the function
2941 silc_client_close_connction. Affected file is
2942 lib/silcclient/client.c.
2944 * Do not execute the KILL command for clients that are in
2945 history (ie. they are not in the network). Affected file is
2948 * Fixed KILL notify handling, client does not crash anymore.
2949 Affected file irssi/src/silc/core/silc-channels.c.
2951 * Reduced the default packet buffer size from 2048 to 1024 in
2952 lib/silccore/silcpacket.c.
2954 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2955 counter to the SKE context that is incresed when the SKE library
2956 performs async operation outside the library. If the outside
2957 process frees the SKE context and FREED status will be set
2958 and the library will detect after the sync operation that the
2959 libary is freed. The affected files are
2960 lib/silcske/silcske[_status].[ch].
2962 * Resolve the client entry information in the function
2963 silc_client_channel_message to assure that NULL pointer is not
2964 passed as client entry to the application. */
2966 * Fixed the task timeout calculation to assure that there is
2967 never negative timeouts. The affected file is
2968 lib/silcutil/silcschedule.c.
2970 * Fixed the channel user mode notification sending in server.
2971 It was sent point-to-point to the router (or to server by router)
2972 but it needs to be destined to a channel. The routines now
2973 supports sending the channel user mode notifys to the channels
2974 when announcing clients and channels. Affected files are
2975 silcd/server.c and silcd/packet_receive.c.
2977 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2978 It did not actually replace the old channel entry in the cache.
2979 Affected file lib/silcclient/client_notify.c.
2981 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2983 * Fixed a possible crash in silc_packet_send_prepare. It now
2984 assures always that there is enough space in the buffer and
2985 at the tail area of the buffer (for MAC).
2987 Fixed the inbound buffer reallocation in silc_packet_read.
2988 It was old code and did not handle the reallocation correctly.
2991 The affected file is lib/silccore/silcpacket.c.
2993 * Fixed buffer overflow in silc_parse_nickname in the file
2994 lib/silcutil/silcutil.c.
2996 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2998 * make install generates new server keys only if there is not
3001 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3003 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3004 Added check that if the NOREPLY is set then we will not send
3005 the away message. This avoids infinite loop of away messages
3006 if both clients are away. The affected file is
3007 lib/silcclient/client_prvmsg.c.
3009 * Fixed client crash if /NICK was given without arguments.
3010 Affected file lib/silcclient/command.c.
3012 * Server does not send the invite list in INVITE command back
3013 to the client if the list was not altered. Added this notion
3014 to the protocol spec as well. Affected file silcd/command.c.
3016 Fixed possible crash in INVITE command by checking the
3017 value of silc_server_get_client_route command.
3019 * Fixed the INVITE notify type handling. The arguments are now
3020 taken in correct order and client does not crash. The affected
3021 file is irssi/src/silc/core/silc-channels.c.
3023 Removed the "Inviting xxx to channel" message from the
3024 client library away and let the application handle it.
3025 Affected file lib/silcclient/command.c. Added that message
3026 to Irssi SILC client's message formats.
3028 * Fixed CMODE command crash in client. It now checks the
3029 amount of arguments correctly and does not crash. The affected
3030 file is lib/silcclient/command.c.
3032 * Do not create new channel automatically in silc_channels_join
3033 but check whether the channel by that name already exists.
3034 Affected file irssi/silc/core/silc-channels.c.
3036 * Do not send the SERVER_SIGNOFF to router if the disconnected
3037 entity was the router. Affected file silcd/server.c.
3039 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3040 SILC client as it was missing from there.
3042 Added the handling of the KICK notify to the Irssi SILC client
3043 as it was missing. Added "you have been kicked" message to
3044 Irssi SILC client's message modules formats.
3046 Added the handing of the KILL notify to the Irssi SILC client
3047 as it was missing. Added the kill message module formats
3050 The affected file is irssi/src/silc/core/silc-channels.c.
3052 * The router did not save the channel mode the server announced.
3053 Affected file silcd/packet_receive.c.
3055 * Fixed a possible crash in INFO command in server. If the
3056 server did not provide the server info it crashed. Affected
3057 file silcd/command.c.
3059 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3061 * Fixed the GETKEY command in the server to check also the
3062 global list. Otherwise the GETKEY would not work correctly
3063 in normal SILC server. Affected file silcd/command.c.
3065 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3067 * Fixed GETKEY crash, it crashed if the command did not succseed.
3069 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3071 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3072 is now real and not just an macro interface to GMP.
3074 Removed the entire GMP from the source tree and imported new
3075 NSS MPI library instead. Reason for removing GMP is that it is
3076 extremely large and compiles extremely slow. The NSS MPI
3077 is only a few files and compiles in less than 10 seconds.
3078 The speed is also about the same as GMP. The MPI is imported
3079 to lib/silcmath/mpi.
3081 If the system has GMP installed we will still use the GMP.
3082 If it is not then the NSS MPI will be compiled.
3084 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3086 * Merged a long nickname (127 characters long) crash bugfix from
3087 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3089 * Merged a freed memory reference bugfix from Irssi CVS tree.
3090 Affected file irssi/src/core/commands.c.
3092 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3094 * Added the server's public key sving and verification to the
3095 server when performing the SKE. This was missing and the
3096 remote server's (or router's) public key was accepted without
3097 checking whether we have it previously or trust it at all.
3098 Affected file silcd/protocol.c.
3100 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3102 * Check in the silc_server_timeout_remote if protocol is active
3103 and make sure that the protocol's final callback is called so
3104 that all memory if freed. Affected file silcd/server.c.
3106 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3108 * silc_server_whois_send_reply crashed the server if the nickname
3109 was 127 characters long. Affected file silcd/command.c.
3111 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3113 * Added sanity check to the silc_server_new_client. If the hostname
3114 is provided inside username then check that the provided hostname
3115 really is the same as the resolved one. If the hostname was not
3116 resolved then check it from the public key. Affected file is
3117 silcd/packet_receive.c.
3119 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3120 if the server disconnected us and the connection is not valid
3121 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3123 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3124 the library to the lib/silcutil/silcutil.[ch].
3126 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3128 * Close log file after open. Affected file
3129 lib/silcutil/silclog.c.
3131 * Check whether sock == NULL in silc_client_send_packet and return
3132 if it is. Affected file lib/silcclient/silcclient.c.
3134 * Check rec->entry == NULL in the Irssi SILC Client before
3135 sending the channel message. Affecte file is
3136 irssi/src/silc/core/silc-servers.c.
3138 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3140 * Merged a splitted window bugfix from Irssi CVS tree. The
3141 affected file is irssi/src/fe-text/textbuffer-view.c.
3143 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3144 It did not print nickname.
3146 * Improved the distributions system a bit.
3148 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3150 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3151 irssi/src/fe-text/gui-window.c.
3153 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3154 to in-active server. The affected file is
3155 irssi/src/silc/core/client_ops.c.
3157 * Resolve the client in USERS command reply if the entry does
3158 not have username resolved. The affected file is
3159 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3160 command to WHOIS command to really resolve stuff. The USERS
3161 is not used any more in any critical section so WHOIS can
3162 be used even though it might be slower than IDENTIFY.
3164 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3167 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Changed the protocol API a bit more consistent in the
3170 lib/silccore/silcprotocol.[ch].
3172 * Changed the following headers to ROBODoc format:
3174 lib/silccore/silcpayload.h
3175 lib/silccore/silcprotocol.h
3176 lib/silccore/silcsockconn.h
3178 All core library headers are now formatted.
3180 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3182 * Fixed a bug in Irssi SILC client; do not show that you are
3183 server/router operator if you really are not. Affected file is
3184 irssi/src/silc/core/client_ops.c.
3186 * Renamed silc_command_free_payload to silc_command_payload_free.
3187 Affected file lib/silccore/silccommand.h
3189 * Added silcmath.h to include the prototoypes of various routines
3190 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3193 * Changed the following headers to ROBODoc format:
3195 lib/silccore/silcchannel.h
3196 lib/silccore/silccommand.h
3197 lib/silccore/silcid.h
3198 lib/silccore/silcidcache.h
3199 lib/silccore/silcmode.h
3200 lib/silccore/silcnotify.h
3201 lib/silccore/silcpacket.h
3202 lib/silcmath/silcmath.h
3204 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * Added checking to the server code not to start the server if
3207 ciphers and stuff are not configured properly. Affected files
3208 silcd/serverconfig.[h] and silcd/server.c.
3210 * Changed the layout of the header files of the public interfaces
3211 in the SILC libraries. The new layout supports ROBODoc
3212 documentation tool (and some others) so that it is easy to create
3213 a library reference manual. All the other headers and source
3214 code must still follow the CodingStyle document. Also source
3215 code must not include these ROBODoc stuffs, only the headers.
3216 Furthermore, all public interface headers must now be named
3217 by using `silc' prefix, example: silcapi.h, silccipher.h.
3218 Some files were renamed due to this. All the other headers
3219 must not be used as public interfaces. I will update the
3220 CodingStyle document later. Changed following headers, so far:
3222 lib/silcclient/silcapi.h
3223 lib/silccore/silcauth.h
3224 lib/silccore/silcprivate.h
3225 lib/silccrypt/silcdh.h
3227 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3231 * Removed silc_client_packet_send_flush from the client library
3232 as it is not needed. Affected file lib/silcclient/client.[ch].
3234 * Added printing of message of unresolved authentication method
3235 to the Irssi SILC client. Added it to the module formats.
3236 Removed the same message from the client library.
3238 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3240 * Added new distribution feature, DISTLABEL. Every distribution
3241 can define own preprocessor label that can be used in the
3242 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3243 file distributions, acconfig.h.pre and prepare.
3245 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3247 * Added Makefile.defines_int to include the actual definitions
3248 for Makefile.defines.in. Tested the new distribution system,
3249 created distributions and tested installation.
3251 * Added AWAY message printing to the Irssi SILC client. Added
3252 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3254 * Added SCONNECT command to call the SILC's CONNECT command.
3255 Cannot use CONNECT directly since Irssi uses that internally.
3256 Affected file irssi/src/silc/core/silc-servers.c.
3258 Added ACTION local command. It is same as ME command but takes
3259 the channel as mandatory argument.
3261 Rewrote some of the Irssi's help files to suite for SILC
3264 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3266 * Added Makefile.defines[.in] that should for now on be included
3267 in all Makefile.am file in the source tree. That file includes
3268 all common compilation definitions for SILC source tree.
3270 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3272 * Minor changes to the ./prepare script to change the package
3273 name according the distribution name to the configure.in.
3275 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3277 * Created new distribution system. Added file `distributions'
3278 that defines all the distributions that can be created out of
3279 the SILC source tree. The ./prepare script now reads that
3280 file to determine how to prepare the distributions. The
3281 first argument to the ./prepare is the name of the distribution
3282 and second is the version of the distribution. If given
3283 without arguments it creates the default (toolkit) distribution
3284 with the default version (defined in ./prepare).
3286 All Makefile.am files that are subject to the distributions
3287 are now named as Makefile.am.pre. These are ./Makefile.am
3288 and lib/Makefile.am. Others may be changed later.
3290 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Added invite list, ban list, some key management and connection
3293 error message printing to module formats in the Irssi SILC client.
3295 * Added new silc_client_set_away_message to set the away message
3296 that is back to the person who sent private message. The
3297 affected file lib/silcclient/silcapi.h and the
3298 lib/silcclient/client_prvmsg.c.
3300 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Fixed the private message sending in the Irssi SILC client,
3303 added local command KEY to the Irssi SILC client.
3305 Added key management and key agreement message formats to the
3306 irssi/src/fe-common/silc/module-formats.[ch].
3308 Added USERS (alias WHO) printing, server/router operator
3309 indication and LIST command printing to the module formats.
3311 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3313 * Fixed channel joining notify handling, cumode notify handling
3314 from Irssi SILC client.
3316 * Added SILC specific module-formats to the Irssi SILC client so
3317 that SILC specific message hilighting, colors etc is possible.
3318 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3320 Added channel mode, channel user mode, actions, notices,
3321 whois and whowas printing to the the module-formats.c.
3323 * Fixed a bug in channel deletion in the server. The channel
3324 is not left to the cache even if the channel founder auth mode
3325 is set when there are no users anymore on the channel. Affected
3326 file silcd/server.c.
3328 * The silc_net_localhost now resolves the entire hostname including
3329 the domain name. Affected file lib/silcutil/silcnet.c.
3331 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3333 * Changed the ask_passphrase client operation to be ascynchronous.
3334 It has now a completion callback and a context that the
3335 application must call after it has got the passphrase from
3336 the user. Affected files lib/silcclient/silcapi.h,
3337 lib/silcclient/protocol.c, lib/silcclient/command.c and
3340 Added SilcAskPassphrase callback that the application calls
3341 to deliver the passphrase to the library.
3343 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3344 The public key verification and especially a certificate
3345 verification is asynchronous procedure.
3347 Added new SILC_SKE_STATUS_PENDING status to indicate the
3348 request is pending and a callback will be called to finalize
3351 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3352 indicate that remote end did not send its public key (or
3353 certificate), even though we require it. Added check for this
3354 condition in the SKE. This was a security bug, now fixed.
3356 Defined new SilcSKEVerifyCbCompletion callback that is called
3357 when the verification process is completed.
3359 The affected files lib/silcske/silcske_status.h and
3360 lib/silcske/silcske.[ch].
3362 * Changed the verify_public_key client operation to be async
3363 as well. Defined SilcVerifyPublicKey callback that is used to
3364 indicate the success of the public key verification process.
3366 Changed the server and client to use the new async client
3369 * Changed the Irssi SILC client's internal scheduler to be called
3370 twice as many times as it used to be. As a result the client
3371 should be a bit faster now. Affected file is
3372 irssi/src/silc/core/silc-core.c.
3374 * Added support to Irssi SILC client of asynchronous public key
3375 verification and passphrase inquiry. Affected file is
3376 irssi/src/silc/core/silc-core.c.
3378 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Do not say "You have left channel %s" in client library.
3381 Moved it to the application. Affected files are
3382 lib/silcclient/command.c and silc/client_ops.c.
3384 * Fixed silc_client_get_clients. Command context was not
3385 duplicated and was freed memory in the callback. Affected
3386 file lib/silcclient/idlist.c.
3388 * Do not say "you are now talking..." on JOIN command in the
3389 client library. The appliation must handle it.
3391 * Do not say ".. changed topic to" in command reply in the
3392 client libary. The application must handle it.
3394 * Fixed TOPIC command sending in the client library.
3396 * Fixed a memory leak in silc_client_command_free in the file
3397 lib/silcclient/command.c.
3399 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3401 * Imported a modified version of Irssi client to the source tree.
3402 The Irssi will be used to create a new client called
3403 Irssi SILC. Imported to irssi/.
3405 Added silc_core_init_finish function to the Irssi. Affected
3406 file irssi/configure.in.
3408 A lot changes in the Makefile.ams around the irssi tree.
3410 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3412 * Do not rehash if the new size is same as the old size of the
3413 hash table, in the silc_hash_table_rehash*. The affected file
3414 lib/silcutil/silchashtable.c.
3416 * Replaced hash_table_del_by_context calls from the server
3417 (when channel->user_list and client->channels) to the
3418 hash_table_del as it is sufficient and faster.
3420 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3422 * Added silc_hash_table_list, silc_hash_table_get and the
3423 SilcHashTableList structure to provide an alternative way to
3424 traverse the hash table. The affected files are
3425 lib/silcutil/silchashtable.[ch].
3427 * Changed the server's idlist routines to use the hash table
3428 routines to optimize the code.
3430 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3432 * Replaced the client entry's `channel' list and channel entry's
3433 `user_list' list to hash tables for optimized lookup. Changed
3434 the code to use the hash table interface around the code.
3435 Affected file lib/silcd/idlist.[ch].
3437 * Added `auto_rehash' boolean argument to the function
3438 silc_hash_table_alloc to indicate whether the hash table should
3439 auto-rehash when it thinks is appropriate time. It will
3440 increase the hash table size if the there is twice as much
3441 entries in the table than the size of the table, and will
3442 decrease the size if there are twice as less entries than
3443 the size of the table.
3445 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3449 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3451 * silc_idcache_purge_by_context deletes the entry now by context
3452 as it is supposed to do. Affected file lib/silccore/idcache.c.
3454 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3455 client is not anymore valid (WHOWAS givens the info) and not
3456 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3458 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3460 * Removed the `data' and `data_len' arguments from the ID Cache
3461 interfaces and added `name' argument. ID Cache does not handle
3462 anymore the binary data only a names associated with given ID.
3464 * When hashing a Client ID with silc_hash_id the entire ID is
3465 not hashed anymore, instead only the hash of the Client ID is
3466 hashed. This way we can access the Client ID from the cache
3467 with Client ID but with the hash of the ID (which is a hash of
3468 the nickname) as well without any difference in performance.
3470 Added also silc_idcache_find_by_id_one_ext to do one on one
3471 searching when we have the actual ID. Added also function
3472 silc_hash_client_id_compare. The affected files are
3473 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3475 * When hashing the name associated with a ID it is always done
3476 in lowercase. This way we can access the cache without worrying
3477 about case-sensitivity, even though, for example nicknames are
3480 * Fixed a bug in server with channel message sending. It put
3481 wrong ID type as destination ID. The affected file
3482 silcd/packet_send.c.
3484 * silc_idcache_del_by_context now deletes from all hash tables
3485 by context. Affected file lib/silccore/idcache.c.
3487 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3489 * Changed the client library to use the new ID Cache interface.
3490 Changes around the source tree.
3492 * Added silc_hash_table_rehash_ext to rehash with specific
3493 hash function. Affected file lib/silcutil/silchashtable.[ch].
3495 * Added silc_hash_string_compare to compare two strings in the
3496 hash table. Affected file lib/silcutil/silcutil.[ch].
3498 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3500 * Added new function silc_idcache_del_by_context into the
3501 lib/silccore/idcache.[ch].
3503 * Changed the server's ID list routines to use the new ID Cache
3504 interface. Changes around the source tree.
3506 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3508 * Added silc_hash_table_del[_by_context]_ext functions in to the
3509 lib/silcutil/silchashtable.[ch].
3511 Removed silc_hash_table_find_all* routines and added new
3512 silc_hash_table_find_foreach to replace them.
3514 Added silc_hash_table_replace_ext function as extended
3515 replacing function. Separated the simple hash table interface
3516 from the extended hash table interface in the file
3517 lib/silcutil/silchashtable.h.
3519 * Fixed minor bugs and changed it to use some of the new
3520 hash table functions in lib/silccore/idcache.c
3522 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Added new function silc_hash_table_find_all to return all keys
3525 in the hash table by the specified key. As the hash table is
3526 collision resistant it also makes it possible to have several
3527 duplicate keys in the hash table. This function may be used to
3528 find all of the keys from the hash.
3530 Added user_context arguments to the SilcHashFunction,
3531 SilcHashCompare and SilcHashDestructor to deliver user specified
3534 Added new fuctions silc_hash_table_find[_all]_ext to do
3535 extended lookup with specified hash and compare functions and
3536 specified user contexts.
3538 Added new function silc_hash_table_add_ext to add the key
3539 with specified hash function and user context.
3541 Added new function silc_hash_table_foreach to traverse all
3542 entrys in the hash table. Added SilcHashForeach callback
3545 Added new function silc_hash_table_del_by_context to delete
3546 the entry only if the context associated with the key matches.
3548 Affected files are lib/silcutil/silchashtable.[ch].
3550 * Removed silc_hash_[server/client/channel]_id and added just
3551 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3552 silc_hash_id_compare to compare two ID's using as the hash table
3553 comparison function. Added also silc_hash_data to hash
3554 binary data and silc_hash_data_compare to compare it.
3556 * Removed silc_idlist_find_client_by_hash as it is not needed
3557 anymore. Affected file silcd/idlist.[ch].
3559 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3560 to use internally the SilcHashTable. The new ID Cache is a lot
3561 faster than the old one. Some of the ID Cache interface was also
3562 rewritten and obsolete and stupid functions were removed.
3564 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3566 * Added entry_count field to the SilcHashTable to keep the number
3567 of the entries in the table. Implemented the function
3568 silc_hash_table_rehash. Added new function
3569 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3571 Fixed a minor bug in silc_hash_table_free.
3573 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3574 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3575 into the lib/silcutil/silcutil.[ch].
3577 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3579 * Implemented a collision resistant hash table into the
3580 lib/silcutil/silchashtable[ch]. See the header and the source
3581 for the SilcHashTable API.
3583 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3585 * Merged dotconf version 1.0.2 into lib/dotconf.
3587 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3589 * Do not compile anything in lib/silcsim/* if the SIM support
3590 is not enabled. The tree should now compile without problems
3593 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3595 * Compiled the SILC under cygwin. Compiled and tested briefly
3596 without problems. More tests needed. The SIMs didn't compile
3599 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3601 * Fixed possible crash in silc_get_username in the
3602 lib/silcutil/silcutil.c.
3604 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3606 * Fixed a va_arg in silc/client_ops.c.
3608 * Oops, RC5 routines were named AES and caused some problems
3609 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3611 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Added new SilcIDIP structure into the lib/silccore/id.h and
3614 replaced the old `ip' fields from all SILC ID's to that type.
3615 This is a step towards IPv6 support.
3617 The silc_id_get_len takes now the ID as an extra argument.
3618 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3619 both IPv4 and IPv6 based ID's.
3621 The affected files are lib/silccore/id.[ch] and other files
3622 around the tree using these routines.
3624 * Removed the ID length arguments in server from various
3625 silc_server_send_notify_* routines -> they are not needed
3628 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * Fixed memory leak in silc_encode_pem_file in the file
3631 lib/silcutil/silcutil.c.
3633 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3635 * Check minor version as well in the SKE. Affected files are
3636 silcd/protocol.c and lib/silcclient/protocol.c.
3638 * Added --identifier option to the server so that an identifier
3639 can be when creating the public key for the server. Affected
3640 file is silcd/silcd.c.
3642 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3643 lib/silccrypt/silcpkcs.c.
3645 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3647 * Register default ciphers and stuff when using -C option with
3648 the server. Affected file sildc/silcd.c.
3650 * Put back the servers public key filename format, it is better
3651 than the new one. For now, the client keys are saved with the
3652 new filename format. The affected file silc/client_ops.c.
3654 * Implemented the Cipher API for the rest of the ciphers that
3655 did not implement it or implemented it the wrong way.
3657 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3659 * Register default ciphers and stuff when using the -S option
3660 in the client. Affected file silc/silc.c. Same also when
3661 creating new key pair with -C option.
3663 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3665 * Fixed the silc_verify_public_key client operation function to
3666 save the public keys differently. The fingerprint is now
3667 used as filename and not the hostname. This way also the
3668 client keys are saved uniquely and not with hostnames. The
3669 affected file is silc/client_ops.c.
3671 * Trimmed the silc_hash_fingerprint function to remove extra
3672 whitespaces from the end of the fingerprint. The affected
3673 file is lib/silccrypt/silchash.c.
3677 * Added silc_cipher_register_default function to register all
3678 default ciphers. It can be used when configuration files
3679 does not exist and the application does not want any specific
3680 ciphers in any specific order.
3682 The SilcDList is now used as silc_cipher_list dynamically
3683 allocated cipher list. Removed the static list all together
3684 and now all ciphers must be allocated to the dynamic list.
3685 The silc_cipher_alloc routine was changed to check only the
3688 All silc_cipher_* routines that used to return int returns
3691 The affected files lib/silccrypt/silccrypt.[ch].
3693 * The same thing was done to silc_hash_* as for silc_cipher_*
3694 routines. Affected files lib/silccrypt/silchash.[ch].
3696 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3697 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3698 Added also silc_pkcs_[un]register[_default] functions.
3699 Removed the data_context from the PKCS API.
3701 * Added silc_hmac_register_default function to register default
3702 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3703 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3704 to unregister all hmacs at once.
3706 * Register the default ciphers, hash functions, PKCSs and HMACs
3707 if client's configuration file does not exist. The affected
3710 * The client did not load the hash functions from the SIM
3711 modules at all. Added support for this. Affected file is
3712 silc/clientconfig.c.
3714 * When decoding public key with silc_pkcs_public_key_decode, check
3715 the supported algorithm only if PKCS are registered. Affected
3716 file lib/silccrypt/silcpkcs.c. The same was done with the
3717 silc_pkcs_private_key_decode.
3719 * Fixed the SILC List routines to keep the list always in order.
3720 It used to change the list's order when traversing the list but
3721 not it preserves the order. Affected file lib/trq/silclist.h.
3723 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3725 * Added the client library to use the SilcSocketConnection's
3726 reference counter (by silc_socket_dup) to prevent the bug that
3727 the socket object may be freed underneath async operation.
3729 * The name resolv library checking fixes in the configure.in.pre.
3732 * Created new version of the protocol drafts for future
3733 development. The -03 drafts are the ones that will be changed
3734 in the trunk now and the -02 will remain as they are.
3736 * Send list of CUMODE notifys to the router when announcing
3737 the channel users to the router. Affected file silcd/server.c.
3738 If the router receiving channel founder CUMODE for a channel
3739 that already has channel founder it will send CUMODE notify
3740 to the sender to remove the channel founder rights from the
3741 announced client. Affected file silcd/packet_receive.c.
3743 * The CUMODE notify may now use Server ID as well as the entity
3744 who changes the mode. Updated protocool specs.
3746 * Updated INSTALL and README files.
3748 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3750 * New web pages in the http://silc.pspt.fi. The pages was
3755 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3757 * Implemented the [DenyConnectin] config section in the server.
3758 Added silc_server_config_denied_conn to check whether incoming
3759 connection is denied. Affected file silcd/serverconfig.[ch].
3761 * Do not check the ports when checking the incoming configuration
3762 data if the port is 0, meaning any. Affected file is
3763 silcd/serverconfig.c.
3765 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3767 * Fixed buffer overflow in silc_string_compare in the file
3768 lib/silcutil/silcutil.c.
3770 * Fixed double free in silc_server_command_leave in the file
3773 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Fixed the version checking in the server. Affected file is
3778 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3780 * Fixed the configuration data fetching when accepting new
3781 connections in the server. Affected file silcd/server.c.
3783 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Added `sender_entry' argument to the function
3786 silc_server_packet_relay_to_channel so that we can check
3787 whether some destination actually belongs to the same route
3788 the sender belongs (ie, we must not resend the packet to the
3789 sender). Affected file silcd/packet_send.[ch].
3791 * Added `servername' field to the SilcClientEntry in the server
3792 to hold the name of the server where client is from. Affected
3793 file is silcd/idlist.h.
3795 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3797 * Moved the channel message encrypting in the router betwen
3798 router connections from silc_server_channel_message to the
3799 silc_server_packet_relay_to_channel since we want to check
3800 whether we have anybody channel before encrypting anything.
3801 Affected files silcd/packet_[receive/send].c.
3803 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Fixed the [AdminConnection] server config section to support
3806 multiple entries. Affected file silcd/serverconfig.c.
3808 * Added support into the server to check the validity of the
3809 incoming connection before executing any KE or authentication
3812 * The connection configuration is now saved to the KE and
3813 connection auth protocol contexts and not fetched anymore in
3814 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3816 * The local hosts listenning address and port is also resolved
3817 now when starting the server. We want to have the socket object
3818 to include the real address and port for the listener. Added
3819 new function silc_net_check_local_by_sock into the files
3820 lib/silcutil/silcnet.[ch].
3822 * Fixed a broadcast bug in server -> do not broadcast if we
3825 * Fixed a routing bug. Do not route broadcast packets ever.
3826 Broadcast packets must be processed always and not routed since
3827 they may be destined to some other host than yourself and thus
3828 would get routed without no good reason. Affected file is
3831 * Added function silc_server_config_is_primary_route to check
3832 whether primary router connection has been configured (a router
3833 configuration that we are initiating). If there is not, we
3834 will assume that there is only two routers in the SILC network
3835 and we will use the incoming router connection as our primary
3836 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3838 * Changed the order of the broadcasting. Broadcast _after_ the
3839 packet has been processed not before. Affected file is
3842 * Fixed a [ClientConnection] parsing bug. The port was never
3843 parsed correctly thus resulting to port 0. Affected file
3844 silcd/serverconfig.c.
3846 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3847 argument and did not set the broadcast packet flag. Affected
3848 file silcd/packet_send.c. Fixed same bug in the function
3849 silc_server_send_notify as well.
3851 * If we receive NEW_ID packet for our own ID in the server, ignore
3854 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3858 * Removed the nickname from the Private Message Payload.
3859 Updated the code and the protocol specs.
3861 * Updated protocol specs for submitting to the IETF.
3863 * Tweaked the Random Number Generator a bit. Affected file
3864 lib/silccrypt/silcrng.c. Exported a new function
3865 silc_rng_[global]_add_noise which can be used to add more
3868 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3870 * Do not parse packets with different timeout when protocol
3871 is active -> may cause problem with rekey. Affected file
3874 * When server receives signoff notify it must not create
3875 new channel key if the client is on any channels since the
3876 sender of the signoff notify will create it.
3878 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3880 * Added printing of error messages during SKE protocol from the
3881 failure packet sent by server during SKE. Affected file
3884 * Removed the client's failure_callback handling with timeout
3885 and handle it immediately when received.
3887 * The SKE library returned wrong type in SUCCESS and FAILURE
3888 packets. They must be 32 bit MSB not 16 bit MSB.
3890 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3892 * Ok, rewrote the logic of the re-key and now it seems to work.
3893 I tested it on high traffic with frequent re-keys without
3894 problems. Added hmac_receive (and renamed hmac to hmac_send)
3895 in SilcClientConnection in lib/silcclient/client.h and
3896 in SilcIDListData in silcd/idlist.h. Also, removed the
3897 SilcPacketParserContext's cipher and hmac fields as they are
3898 not needed anymore and actually caused some problems when
3899 the ciphers and hmac's changed underneath the packet parser.
3901 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3903 * If re-key protocol is active then process the incoming packets
3904 synchronously since we must assure that icoming packets encrypted
3905 with the old key is processed before the new keys is set to
3906 use. This is true other packets than for REKEY packets.
3907 Affected file silcd/server.c. The same was done to client library
3908 as well, affected file lib/silcclient/client.c.
3910 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3912 * Fixed bug in client and server to accept the force send if
3913 the packet is send from silc_[server/client]_packet_process
3914 function. Otherwise the packets are never delivered, oops.
3916 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3918 * Disable force sending of packets when REKEY protocol is active.
3919 We must assure that no packet is sent directly when rekey is
3920 performed. All packets must be sent through packet queue.
3921 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3922 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3923 function is silc_[server/client]_packet_send_real to check
3926 * Replaced the SIM paths from example config files to
3927 /usr/local/modules. Also, make install creates now
3928 /usr/local/silc/logs directory to hold all the SILC server
3931 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3933 * Made the configure.in.pre work on Solaris. Patch by salo.
3935 * Made all ciphers compatible with non-x86 machines. Defined
3936 CBC mode macros into lib/silccrypt/ciphers_def.h.
3938 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Fixed the make install.
3942 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3944 * When MAC computation fails the silc_packet_decrypt returned 0
3945 even though it was supposed to return -1. Fixed this. The
3946 affected file is lib/silccore/silcpacket.c.
3948 * Do not replace the config files in /etc/silc (in make install)
3949 if they already exist. Affected file ./Makefile.am.
3951 * Do not send re-key packets immediately but through packet queue.
3952 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3954 * Changed silc_net_check_host_by_sock to return FALSE if the
3955 IP/DNS could not be resolved. Though, it returns the IP address
3956 now even if it could not resolve it (but returns also FALSE).
3957 Affected file lib/silcutil/silcnet.[ch].
3959 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3961 * Added silc_pkcs_decode_identifier to decode the public key's
3962 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3963 Added also silc_pkcs_free_identifier. Added also new context
3964 SilcPublicKeyIdentifier.
3966 * Added -S option to the silc client. It is used to dump the
3967 contents of the specified public key file.
3969 * Changed the PKCS api to return the public key length when
3970 setting the public key.
3972 * Fixed a fatal bug in the public and private key file loading.
3973 Affected file lib/silccrypt/silcpkcs.c.
3975 * Execute the packet parsing for client with zero (0) timeout
3976 if the protocol is active. Affected file silcd/server.c.
3978 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3980 * Made the key generation options to the silcd program. Added
3981 -C option, equivalent to client's option.
3983 * Added new [ServerKeys] config section to the server. It
3984 configures the server's public and private key.
3986 * Defined generic Public Key Payload into the protocol
3987 specification to send specific type of public keys and
3990 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3991 public key or certificate.
3993 * Implemented the GETKEY command to the server and to the
3994 client library and on user interface.
3996 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Made preliminary `make install' work.
4000 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4002 * Added SilcServerRekey context into silcd/idlist.h.
4004 * Added the PFS support as defined in the specification to the
4005 SKE protocol. Affected files lib/silcske/*.c.
4007 * Added `ske_group' field to the SilcServerRekey context to hold
4008 the number of the SKE group that is used with PFS in re-key.
4009 Affected file silcd/idlist.h.
4011 * Added PFS re-key support to the server. Affected file is
4014 * Added silc_protocol_cancel to cancel execution of the next
4015 state of the protocol. Affected file is
4016 lib/silccore/silcprotocol.[ch].
4018 * Added the re-key support with and without PFS to the client
4019 library. Re-key is performed once in an hour, by default.
4021 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4022 Added silc_client_rekey_callback and silc_client_rekey_final.
4023 Affected files are lib/silcclient/protocol.[ch] and
4024 lib/silcclient/client.[ch].
4026 * Removed the `hmac_key' and `hmac_key_len' fields from the
4027 SilcClientConnection structure; not needed. Affected file is
4028 lib/silcclient/client.h.
4032 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4034 * Do not ask whether user wants to use the negotiated private key
4035 for private messages, just use it. Affected file is
4036 silc/local_command.c.
4038 * Added `send_enc_key' and `enc_key_len' fields to the
4039 SilcIDListData structure since they are needed in the re-key
4040 phase. Affected file is silcd/idlist.[ch].
4042 * Implemented the simple re-key protocol into the server.
4043 Affected files silcd/server.c and silcd/protocol.[ch]. The
4044 re-key will be performed once in an hour, by default.
4046 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4047 Added silc_server_rekey, silc_server_rekey_callback and
4048 silc_server_rekey_final.
4050 * Removed Tunneled flag from the protocol. Updated the code
4051 and the specifications.
4053 * Adde `pfs' field to the SilcIDListData to indicate whether
4054 the PFS is to be performed in the re-key. Affected file is
4057 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4059 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4060 int64 of at least the xintXX size. If void * is less that 4
4061 bytes uint32 * will be used. Defined bool as boolean.
4063 * Changed _ALL_ unsigned long and unsigned int to uint32,
4064 unsgined short to uint16 in the source tree.
4066 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4067 not handle clients that has entry->data.registered == FALSE.
4068 They are not in the network anymore. Affected file is
4071 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4073 * Implemented the sending of the SERVER_SIGNOFF notify in the
4074 server. Affected file is silcd/server.c.
4076 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4077 Added also silc_notify_payload_encode_args into the
4078 lib/silccore/silcnotify.[ch].
4080 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4081 Affected file silcd/packet_receive.c.
4083 * Implemented the SERVER_SIGNOFF notify handling in the client
4084 library. Affected file lib/silcclient/client_notify.c. Also,
4085 implemnted the printing of the SERVER_SIGNOFF info to the
4086 application. Affected file silc/client_ops.c.
4088 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4089 if the deleting was successful. Affected file silcd/idlist.[ch].
4091 * Added support for public key authentication in the connection
4092 authentication protocol in the client library. Affected file
4093 lib/silcclient/protocol.c.
4095 * Changed the server's silc_idlist_get_clients_by_* interface
4096 to support already allocated array so that new entries may be
4097 added to pre-allocated array. Affected file silcd/idlist.[ch].
4098 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4099 and command replies.
4101 * All command reply functions in the server now calls the
4102 pending command callback even if error occured. This way the
4103 error will be delivered to the client as well. Affected files
4104 silcd/command.c and silcd/command_reply.c.
4106 * Fixed INFO command to return local server's info if no server
4107 was provided. Affected file lib/silcclient/command.c.
4109 * Removed RESTART command for good. Updated the code and the
4112 * Rewrote parts of the task system. It is a bit simpler now.
4113 Removed unsued task priorities. The affected files are
4114 lib/silcutil/silctask.[ch].
4116 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4118 * Moved the USERS printing from the library to the application.
4119 Affected files lib/silcclient/command.c and silc/client_ops.c.
4121 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4125 * Added channel key re-key support. The re-key is perfomed
4126 only by the router and is done once in an hour. Added `rekey'
4127 field to the SilcChannelEntry in the server. Affected files
4128 silcd/server.c and silcd/idlist.h.
4130 * Added silc_task_unregister_by_context into the file
4131 lib/silcutil/silctask.[ch].
4133 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4135 * Added SILC_UMODE_GONE mode to indicate when the client is not
4136 present in the SILC network. Added also support to the local
4137 command AWAY that will set this mode. Added support of showing
4138 "xxx is gone" in WHOIS command. The USERS command shows the
4139 gone status as well.
4141 * Fixed setting server and router operator privileges in the
4142 server's UMODE command. Affected file silcd/command.c.
4144 * Merged the SKE KE1 and KE2 payloads into one payload. The
4145 new KE payload is equivalent to the old KE2 payload.
4147 Cleaned up the SKE Start Payload parsing. It now uses the
4148 simple buffer unformatting to do the parsing. A lot faster
4151 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4152 to the SKE that is used to indicate whether both of the SKE
4153 parties should perform authentication. By default only the
4154 responder performs authentication. By setting this flag also
4155 the initiator must do authentication. By default it is unset
4156 since in normal SKE case, client to server connection, only
4157 the responder should do authentication. When doing SKE between
4158 two clients both should perform authentication. Updated the
4159 code and the protocol specs.
4161 * A little fix to IDENTIFY command in the server. Search the
4162 client first by hash not nickname. Affected file is
4165 * Fixed the silc_client_close_connection to support closing
4166 the client to client connections wihtout deleting too much
4167 data. Affected file lib/silcclient/client.c.
4169 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4170 are received if protocol used to be active but is not anymore
4171 the application would crash due to NULL pointer dereference.
4172 Affected files silcd/server.c and lib/silcclient/client.c.
4174 * Added `hash' field to the SilcClientConnection to include
4175 the hash function negotiated in the SKE protocol.
4177 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4178 to set the channel founder authentication data. A client can
4179 claim the founder rights later by providing the authentication
4180 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4181 This way the channel founder can regain the channel founder
4182 privileges even it is left the channel. This works only on
4183 local server and the client must be connected to the same
4184 server to be able to regain the founder rights. Updated the
4185 protocol specs accordingly.
4187 Added support to the CMODE command in the client to set the
4188 founder auth data. Read the README to see how to set it.
4190 Added support to the CUMODE command to claim the founder
4191 rights. Read the README to see how to do it.
4193 Added support for the founder authentication to the Channel
4194 Entry in the server. Affected file silcd/idlist.h.
4196 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4197 server's CMODE command. Affected file silcd/command.c.
4199 * Added the following new functions into lib/silccore/silcauth.[ch]:
4200 silc_auth_get_method and silc_auth_get_data.
4202 * The server now saves the remote hosts public key to the
4203 SilcIDListData pointer. Affected file silcd/protocol.c.
4205 * The normal server now does not remove the channel entry from
4206 the cache if the founder authentication data is set. It used
4207 to remove it if the founder was the last one on the channel on
4208 the server and left the channel. The auth data is saved and
4209 if the channel is re-joined later the old entry is used with
4210 the old auth data. Affected files silcd/command_reply.c and
4213 * Removed the `pkcs' field from the SilcIDListData structure
4214 in the server; it is not used. Affected file silcd/idlist.h.
4216 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4218 * Fixed packet processing on slow links. Partial packets were
4219 never re-processed because the incoming data buffer was cleared
4220 by the application. Application must not directly clear the
4221 sock->inbuf, the packet processing routines handle it. Fixed
4222 this in client library and in server.
4224 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4226 * Fixed the WHOIS and IDENTIFY send reply function to really
4227 check whether to send list or just one entry. Affected file
4230 * Cleaned up the LEAVE command's channel key distribution. The
4231 affected file silcd/command.c.
4233 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4234 can enforce the channel mode as well. In that case the ID
4235 includes the ID of the server. The code now enforces the
4236 mode change if the router have different mode than the server.
4238 * The notify client operation with CMODE_CHANGE notify can now
4239 return NULL client_entry pointer if the CMODE was not changed
4240 by client. Application must check for this.
4242 * Added <Server ID> argument to INFO command to support server
4243 info fetching by Server ID.
4245 * Added silc_server_announce_get_channel_users to get assembled
4246 packets of channel users of the specified channel. Affected
4247 file silcd/server.[ch].
4249 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4250 was freed underneath the ID Cache.
4252 * Re-announce clients when the server received CHANNEL_CHANGE
4253 notify from the router. Affected file silcd/packet_send.c.
4255 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4257 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4258 crashed since it did not handle the fact that there is no cipher
4259 called "3" and didn't check the error condition. Now fixed.
4261 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4262 flag. It can be used to send message requests.
4264 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4266 * Implemented the RESTART command in the client.
4268 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4269 notice type messages. Added notice printing to the user
4272 * The channel keys are not re-generated if the channel's mode
4273 is PRIVKEY, ie private key on the channel exists. Affected
4274 files silcd/server.c and silcd/command.c.
4276 * Fixed a little bug in channel message delivery when channel
4277 private keys are set in the server. Affected file is
4278 silcd/packet_send.c.
4280 * Changed the setting on channel->on_channel = TRUE from the
4281 silc_client_save_channel_key to the JOIN command reply. The
4282 key payload is not received if the private channel key is set.
4283 Affected file lib/silcclient/command_reply.c and the
4284 lib/silcclient/client_channel.c.
4286 * When the CMODE_CHANGE notify is sent and the channel private
4287 key mode is removed the channel key must be re-generated in
4288 other cells as well. Added this support for the router in the
4289 silcd/packet_receive.c.
4291 * Added new local command NOTICE to send notice message on
4292 channel. Affected file silc/local_command.[ch].
4294 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4296 * Added new local command ME to the client. It is used to send
4297 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4298 some action. Affected file silc/local_command.[ch].
4300 * Changed channel_message and private_message client operations
4301 to deliver the message flags to the application. Added also
4302 the `flags' arguments to the silc_client_send_channel_message
4303 and silc_client_send_private_message functions. Affected file
4306 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4308 * Redefined the Private Message Payload to support private message
4309 keys and to support the new private message flags. Updated
4310 the protocol specs. Flags makes it possible to have for example
4311 CTCP style messages.
4313 * Added new type SilcPrivateMessagePayload and defined an API
4314 for it in the lib/silcclient/silcprivate.[ch].
4316 * Tested private message private keys successfully. Tested the
4317 private message key set, unset and list commands with the new
4320 * Redefined the Channel Message Payload to include the channel
4321 message flags (equal with private message flags) to support
4322 for example CTCP style messages.
4324 * Defined some of the message (for channel and private message)
4325 flags. Updated the protocol specs and added the flags to the
4326 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4328 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Added SilcKeyAgreementStatus type to the key agreement routines
4331 to indicate the current status and error if one occured.
4332 The status types are defined in the lib/silcclient/silcapi.h.
4334 * Added new local command KEY that is used to set and unset private
4335 keys for channels, set and unset private keys for private messages
4336 with remote clients and to send key agreement requests and
4337 negotiate the key agreement protocol with remote client. The
4338 key agreement is supported only to negotiate private message keys,
4339 it currently cannot be used to negotiate private keys for channels,
4340 as it is not convenient for that purpose.
4342 * Fixed a minor pending callback setting bug in the function
4343 silc_client_get_client_by_id_resolve, now the function works.
4344 Affected file lib/silcclient/idlist.c.
4346 * Added function silc_net_get_local_port to get local bound
4347 port by socket. Added to lib/silcutil/silcnet.[ch].
4349 * Added `sockets' and `sockets_count' fields to the SilcClient
4350 object. They hold the sockets of the listenning sockets in
4351 the client. Listenning sockets may be for example the key
4352 agreement server. Affected file lib/silcclient/client.[ch].
4353 Added functions the silc_client_add_socket and the
4354 silc_client_del_socket. They are exported to the application
4357 * Added ~./silc/clientkeys to support other client's public keys.
4359 * Renamed verify_server_key client operation to verify_public_key
4360 and added one argument to indicate the type of the connection
4361 (server, client etc.).
4363 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4365 * Added silc_server_connection_auth_request to handle the
4366 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4367 silcd/packet_receive.[ch].
4369 * Added silc_server_send_connection_auth_request into the
4370 silcd/packet_send.c to send the connection auth request packet.
4372 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4375 * Fixed the public key authentication in responder side in the
4376 server. The `auth_data' pointer includes the SilcPublicKey
4377 not the path to the public key. Affected file silcd/protocol.c.
4379 * Implemented the public key authentication in the initiator side
4380 in the server. Affected file silcd/protocol.c.
4382 * Removed the [RedirectClient] config section from the server
4383 configuration. Is not needed and I don't want to implement it.
4385 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4387 * Cleaned up the CMODE command in the server. It now works
4388 correctly and supports all the modes defined in the protocol.
4389 Affected file is silcd/command.c.
4391 * Added `hmac_name' field to the SilcChannelEntry in the server
4392 to hold the default HMAC of the channel. It can be set when
4393 creating the channel (with JOIN command). Affected files
4396 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4397 type to indicate the change of the current cipher and hmac
4398 on the channel. Client can safely ignore the <cipher> argument
4399 (if it chooses to do so) since the CHANNEL_KEY packet will
4400 force the channel key change anyway. The <hmac> argument is
4401 important since the client is responsible of setting the new
4402 HMAC and the hmac key into use.
4404 * Fixed the CMODE command in the client library as well.
4406 * Tested CMODE command in router environment successfully.
4408 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Show the version of the remote client (or server) when connecting
4411 to the server. It is logged to the log file. Affected file
4412 is silcd/protocol.c.
4414 * Fixed the KILLED notify handling in the client library. The
4415 client must be removed from all channels when receiving the
4418 Also, do not remove the client entry when giving the KILL
4419 command but when the KILLED notify is received.
4421 * Removed silc_idlist_find_client_by_nickname from the server.
4422 Not needed anymore. Affected files silcd/idlist.[ch].
4424 * Implemented the CHANNEL_CHANGE notify type handling to the
4425 server. Affected file silcd/server.c.
4429 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4431 * Added silc_server_send_notify_invite to send the INVITE
4432 notify between routers.
4434 * Implemented the INVITE command correctly to the server.
4436 * Implemented the INVITE notify type handling in the server.
4438 * Implemented the INVITE command to the client library and on the
4441 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4443 * Added function silc_server_get_client_resolve to find the
4444 client entry by ID from all ID lists and then resolve it
4445 (using WHOIS) if it cannot be found. Affected file is
4448 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4450 * Implemented the BAN command to the client library.
4452 * The JOIN command in the server now checks the invite list
4455 * Changed the silc_command_reply_payload_encode_va and the
4456 silc_command_payload_encode_va to support that if argument is
4457 NULL it ignores and checks the next argument. Affected file
4458 lib/silccore/silccommand.c.
4460 * Added silc_server_send_notify_ban to send the BAN notify
4461 type between routers.
4463 * Chaned the silc_notify_payload_encode to support that if
4464 argument is NULL it ignores and checks the next argument.
4465 Affected file lib/silccore/silcnotify.c.
4467 * Tested ban lists in router environment successfully.
4469 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4471 * Implemented BAN command to the server, in silcd/command.[ch].
4473 * Removed the BAN and INVITE_LIST modes from the CMODE command
4476 * Added function silc_string_match to regex match two strings.
4477 Affected files lib/silcutil/silcutil.[ch].
4479 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Redefined parts of the SilcChannelEntry in the server to support
4482 the new ban and invite lists.
4484 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4486 * Redefined the INVITE command. The same command can be used to
4487 invite individuals to the channel but also to manage the invite
4488 list of the channel (to add to and remove from the invite list).
4489 Updated the protocol specs.
4491 * Added new command SILC_COMMAND_BAN that can be used to manage
4492 the ban list of the channel. Updated the protocol specs.
4494 * Removed the channel modes: the SILC_CMODE_BAN and the
4495 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4496 in the CMODE command. The equivalent features are now available
4497 using INVITE and BAN commands. Updated the protocol specs.
4499 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4500 in the network about change in the current ban list. The notify
4501 type is not used by the client.
4503 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4504 support the invite lists.
4506 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4508 * Added new function silc_string_regexify that converts string
4509 including wildcard characters into regex string that can
4510 be used by the GNU regex library. Added into the file
4511 lib/silcutil/silcutil.[ch].
4513 Added silc_string_regex_combine to combine to regex strings
4514 into one so that they can be used as one regex string by
4515 the GNU regex library. Added into the file
4516 lib/silcutil/silcutil.[ch].
4518 Added silc_string_regex_match to match two strings. It returns
4519 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4521 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4523 * Imported GNU regex to the soruce tree into lib/contrib.
4524 Fixed some compiler warning from the regex.c.
4526 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4528 * Fixed MOTD command in the server to work in router environment.
4530 * Fixed the MOTD command in the client library to support
4531 the server argument in the command.
4533 * Added `nickname_len' argument to the silc_idlist_add_client
4534 in the server, as the `nickname' argument may be binary data
4537 * Added silc_idlist_get_channels to return all channels from
4540 * Implemented LIST command to the server. Affected file is
4543 * Implemented the LIST command to the client library and on the
4546 * Added [<user count>] argument to the LIST command reply.
4547 With private channels the user count is not shown.
4549 * Updated TODO and README.
4551 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4553 * The client entry's data.registered must be TRUE even with
4554 global client entry on global client list. The data.registered
4555 is used to check whether the client is anymore in the network,
4556 for example with WHOWAS command so it must be valid.
4558 * Fixed the WHOWAS command in the server. It now actually works
4559 in router environment. Added function into silcd/command_reply.c
4560 silc_server_command_reply_whowas_save.
4562 * Added silc_idlist_purge function to the silcd/idlist.c
4563 to periodically purge the ID Cache.
4565 * Fixed INFO command in the server. It works now in router
4566 environment. Added <server name> argument to the INFO command
4567 reply. Updated the protocol specs.
4569 * Fixed minor bug in silc_idcache_purge to not purge if the
4570 expire value is zero.
4572 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4573 they were buggy because of the WHOWAS information.
4575 * Fixed local command MSG to handle the async resolving of
4576 the remote client properly. It used to fail the first MSG.
4577 Affected file silc/local_command.c.
4579 * Added `data_len' field to SilcIDCache context.
4581 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4583 * Update TODO. Todo in commands in the server.
4585 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4587 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4588 used by routers as broadcast packet to inform other routers
4589 about the changed user mode.
4591 Implemented the notify handling in the server. Affected file is
4592 silcd/packet_receive.c. Added the function
4593 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4595 * Added new generic Channel Payload and deprecated the New Channel
4596 Payload. The New Channel Payload is now the generic Channel
4599 * Added new argument `mode' to the silc_server_send_new_channel
4600 as it is required in the Channel Payload now.
4602 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4603 and created a new and real SilChannelPayload to represent the
4604 new generic Channel Payload. Implemented the encode/decode
4605 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4607 * Added silc_server_get_client_channel_list to return the list
4608 of channels the client has joined for WHOIS command reply.
4609 Affected file silcd/server.[ch].
4611 * Implemented the channel list sending in the WHOIS command reply
4612 in server and in the client.
4614 Implemented the channel list displaying on the user interface
4615 as well. Affected file silc/client_ops.c.
4617 * Added silc_channel_payload_parse_list to parse list of Channel
4618 Payloads. It returns SilcDList list of SilcChannelPayloads.
4619 Client for example can use this function to parse the list of
4620 channels it receives in the WHOIS command reply. The caller
4621 must free the list by calling silc_channel_payload_list_free.
4622 Affected files lib/silccore/silcchannel.[ch].
4624 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4626 * Added one new argument <user mode> to the WHOIS command reply
4627 to return the mode of the user in SILC. Updated the protocol
4630 Implemented it to the server and client.
4632 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4634 * Fixed the mode printing on the user interface on joining.
4635 Affected file silc/client_ops.c.
4637 * Implemented the UMODE command and user modes in general to the
4638 client library and to the user interface.
4640 * Implemented the UMODE command to the server.
4642 * The server now sends UNKNOWN_COMMAND error status if client sends
4643 unknown command. Affected file silcd/command.c.
4645 * All server commands now handle the command identifier the right
4646 way when sending the command reply to the client. The client can
4647 use to identify the command replies with the identifier.
4649 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4651 * Added silc_server_get_client_route to resolve the route to
4652 the client indicated by the client ID. Affected file is
4655 * Added silc_server_relay_packet as general function to relay
4656 packet to arbitrary destination. This deprecates functions
4657 like _send_private_message_key, _relay_notify etc. Affected
4658 file is silcd/packet_send.[ch].
4660 Removed silc_server_send_key_agreement,
4661 silc_server_send_private_message_key and
4662 silc_server_packet_relay_notify functions from the file
4663 silcd/packet_send.[ch].
4667 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4668 server. Affected file silcd/packet_receive.[ch].
4670 * Implemented the KILL command to the client. Implemented the
4671 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4672 Affected files lib/silcclient/command[_reply].c and
4673 lib/silcclient/client_notify.c. Implemented the KILL notify
4674 printing in the user inteface.
4676 * Fixed a lot silc_parse_nick memory leaks from the client
4677 library in the file lib/silcclient/command.c.
4679 * Changed the silc_server_send_notify_on_channels's `sender'
4680 argument from SilcSocketConnection to SilcClientEntry to
4681 check the sender as entry and not as connection object and not
4682 to send to the client provided as argument. The affected file
4683 is silcd/packet_send.[ch].
4685 * The notify packets that are destined directly to the client used
4686 to not to be processed by the server. Now changed that and the
4687 server processes all notify packets. After relaying the packet
4688 to the client the notify packet is processed in the server.
4690 * The silc_server_free_client_data now checks whether there is
4691 pending outgoing traffic for the client and purges the data to
4692 the network before removing the client entry.
4694 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4696 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4697 an client is killed from the SILC Network. Updated the protocol
4700 Added new function silc_server_send_notify_killed to the
4701 silcd/packet_send.[ch].
4703 * Added function silc_server_packet_relay_notify to relay notify
4704 packets that are destined directly to a client. In this case
4705 the server does not process the notify packets but merely relays
4706 it to the client. Affected file silcd/packet_send.[ch].
4708 Added also silc_server_packet_process_relay_notify to check
4709 whereto relay the notify. Affected file is
4710 silcd/packet_receive.[ch].
4712 * Implemented the KILL command to the server.
4716 * Added the backup schema desgined last fall to the protocol
4717 specs for everyone to see. The specification is in the
4718 *-spec-xx.txt draft and the packet type definitions for the
4719 backup routers is in *-pp-xx.txt draft. Thusly, added also
4720 new packet type SILC_PACKET_CELL_ROUTERS.
4722 * A big security problem in the implementation discovered. The
4723 signoff of an client did not cause new channel key generation
4724 which it of course should've done. The channel keys must be
4725 always re-generated when client leaves (or signoffs) the channel.
4726 The silc_server_remove_from_channels funtion now handles
4727 the channel key re-generation.
4729 * Added `sender' argument to the silc_server_send_notify_on_channels
4730 to not to send the client provided as argument. Affected file
4731 silcd/packet_send.[ch].
4733 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4735 * Implemented OPER and SILCOPER commands into the server and
4738 * Added silc_auth_verify and silc_auth_verify_data to verify
4739 the authentication directly from the authentication payload.
4740 It supports verifying both passphrase and public key based
4741 authentication. Affected file lib/silccore/silcauth.[ch].
4743 * Added `hash' field to the SilcIDListData structure. It is the
4744 hash negotiated in the SKE protocol. Affected file is
4747 * Slight redesigning of the SilcAuthPayload handling routines.
4748 Do not send SilcPKCS but SilcPublicKey as argument.
4750 * Implemented the public key authentication support to the
4751 serverconfig. The public key is loaded from the provided path
4752 and saved as authentication data to void * pointer. Thus,
4753 changed the unsigned char *auth_data to void *auth_data;
4755 * Fixed SHUTDOWN command to send the reply before the server
4756 is shutdown. :) Affected file silcd/command.c.
4758 * Fixed fatal bug in CONNECT command. The hostname was invalid
4759 memory and server crashed. Affected file silcd/command.c.
4761 * Fixed fatal bug in CLOSE command. The server_entry became
4762 invalid but was referenced later in the command. Affected file
4765 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4767 * Fixed fatal bug in failure packet handling. Server ignored
4768 the failure and thus crashed when it came.
4772 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4774 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4775 that the command may be executed only once in (about) 2 seconds.
4776 The old SILC_CF_LAG flag is same but allows command bursts up
4777 to five before limiting.
4779 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4780 server code. Various commands now includes the CF_LAG_STRICT
4781 flag to disallow any kind of miss-use of the command.
4783 * Fixed the silc_buffer_unformat to not to allocate any data
4784 if the length of the data is zero. It used to allocate the
4785 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4787 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4789 * Changed the format of AdminConnection configuration section
4790 in the server. Added username of the admin to the format.
4791 Affected files silcd/serverconfig.[ch].
4793 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4794 to return admin configuration data by host, username and/or
4797 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4799 * Implemented WHOWAS command to the server. Added the functions:
4801 silc_server_command_whowas_parse,
4802 silc_server_command_whowas_send_reply,
4803 silc_server_command_whowas_from_client and
4804 silc_server_command_whowas_from_server
4806 * Added <Client ID> argument to the WHOWAS command reply. Updated
4807 the protocol specs accordingly.
4809 * Implemented WHOWAS command and command_reply to the client
4812 Implemented the WHOWAS printing on the user interface.
4814 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4816 * Added new argument to the WHOWAS command reply, the real name.
4817 It is an optional argument. Updated the protocol specs.
4819 * Added SilcIDCacheDestructor callback that is registered when
4820 the SilcIDCache is allocated. The callback is called when
4821 an cache entry in the ID Cache expires, or is purged from the
4822 cache. Added into lib/silccore/idcache.[ch].
4824 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4825 to destruct the client entries when the cache entry expires.
4826 Other ID Cache's in server and in the client library ignores
4829 * If the ID Cache entry's `expire' field is zero then the entry
4830 never expires. Added boolean `expire' argument to the
4831 silc_idcache_add function in the lib/silccore/idcache.[ch].
4832 If it is TRUE the default expiry value is used.
4834 * Added silc_server_free_client_data_timeout that is registered
4835 when client disconnects. By default for 5 minutes we preserve
4836 the client entry for history - for WHOWAS command.
4838 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4840 * Added support to the server to enforce that commands are not
4841 executed more than once in 2 seconds. If server receives
4842 commands from client more frequently, timeout is registered
4843 to process the commands. Affected file silcd/command.c.
4844 Added new function silc_server_command_process_timeout.
4846 * Changed NICK_NOTIFY handling in client library to check that
4847 if the client's nickname was changed, so there is no need to
4848 resolve anything from the server.
4850 * Removed error printing from the WHOIS and IDENTIFY commands.
4851 If error occurs then it is ignored silently in the client library.
4852 The application, however, may map the received error to
4853 human readable error string. The application currently maps
4854 the NO_SUCH_NICKNAME error to string.
4856 * Made the command status message public to the application. Moved
4857 them from lib/silcclient/command_reply.c to
4858 lib/silcclient/command_reply.h. The application can map the
4859 received command status to the string with the
4860 silc_client_command_status_message function.
4862 * Added check to the server to check that client's ID is same
4863 as the Source ID in the packet the client sent. They must
4866 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4868 * Added dist-bzip hook to the Makefile.am to make bzip2
4869 compressed distributions.
4871 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4873 * Server now enforces the maximum length for the nickname and
4874 the channel as protocol specification dictates. 128 bytes for
4875 nickname and 256 bytes for channel name.
4877 * Moved the WHOIS printing to the application. The client libary
4878 does not print out the WHOIS information anymore, the application
4879 must do it. Renamed silc_client_command_reply_whois_print to
4880 the silc_client_command_reply_whois_save.
4882 The client's idle time is also sent to the application now, and
4883 the idle is shown on screen.
4885 * Added silc_client_command_reply_identify_save to save the
4886 received IDENTIFY entries.
4888 * Do not check for channel private keys in message sending and
4889 reception if the channel does not have the PRIVKEY mode set.
4890 Affected file lib/silclient/client_channel.c.
4892 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4894 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4895 just surfaced after chaning the JOIN procedure.
4897 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4899 * Added silc_client_get_clients_by_list to get client entries
4900 from Client ID list, that is returned for example by JOIN
4901 and USERS command replies. The application should use this
4902 function for example when JOIN command reply is received to
4903 resolve the clients already on the channel (library does not
4904 do that anymore as USERS command reply is not used in the JOIN
4905 procedure anymore). Affected files lib/silcclient/silcapi.h and
4906 lib/silcclient/idlist.c.
4908 * JOIN command reply and USERS command reply returns now SilcBuffer
4909 pointers instead of unsigned char pointers when returning
4910 the client list and mode list.
4912 * Added <Client ID> argument to the JOIN command reply, mainly
4913 for the server to identify for which client the command was
4914 originally sent. Updated protocol specs accordingly.
4916 * Added SilcDlist private_key pointer to the SilcChannelEntry
4917 in the client to support the channel private keys. Affected
4918 file is lib/silcclient/idlist.h.
4920 * Added SilcChannelPrivateKey argument to the function
4921 silc_client_send_channel_message so that application can choose
4922 to use specific private ke if it wants to. If it is not provided,
4923 the normal channel key is used, unless private keys are set.
4924 In this case the first (key that was added first) is used
4925 as the encryption key.
4927 * Implemented the support for channel private key handling.
4928 Implemented the following functions:
4930 silc_client_add_channel_private_key,
4931 silc_client_del_channel_private_keys,
4932 silc_client_del_channel_private_key,
4933 silc_client_list_channel_private_keys and
4934 silc_client_free_channel_private_keys
4936 Affected file lib/silcclient/client_channel.c.
4938 * Added the support for the private keys in the channel message
4939 sending and encryption and in the message reception and
4940 decryption. Affected funtions are
4941 silc_client_send_channel_message and silc_client_channel_message.
4943 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * Added SKE's key verify callback to the client library's
4946 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4948 * Removed the statement that server (or router) must send USERS
4949 command reply when joining to the channel so that the client
4950 knows who are on the channel. Instead, the client list and
4951 client's mode list is now sent in the JOIN command reply to the
4952 client who joined channel. This is better solution.
4954 * Added function silc_server_get_users_on_channel and function
4955 silc_server_save_users_on_channel to the silcd/server.[ch].
4957 * Removed function silc_server_command_send_users from the
4960 * Do not show topic on the client library anymore. The topic is
4961 sent in the command reply notify to the application and the
4962 application must show the topic now.
4964 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4966 * Added client searching by nickname hash into the IDENTIFY and
4967 WHOIS commands in the server as they were clearly missing from
4968 them. Affected file is silcd/command.c.
4970 * Fixed a bug in private message receiving in the client library.
4971 The remote ID was freed and it wasn't supposed, now it is
4974 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Minor fix to the channel payload; allocate the data area, as it
4977 needs to be of specific length.
4979 * If the key agreement port is zero then the operating
4980 system will define the bound port. Affected files are
4981 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4983 * Added new function silc_channel_payload_decrypt into the file
4984 lib/silccore/silcchannel.[ch].
4986 * Moved the channel message etc, check from silc_packet_decrypt
4987 to applications. The library calls now a generic
4988 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4989 when the packet is either normal or special. This was done to
4990 allow more wide range of checking that was not allowed when
4991 the code was in library. Now applications can do virtually any
4992 checks to the packet and return to the library the decision how
4993 the packet should be processed. Affected files are
4994 lib/silccore/silcpacket.[ch].
4996 Added silc_server_packet_decrypt_check to the server and
4997 silc_client_packet_decrypt_check to the client library.
4999 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5000 to send with specified source and destination information.
5002 * Channel message delivery between routers was broken after the
5003 channel key distribution was fixed earlier. The channel key
5004 was used be to distributed to other routers as well which is not
5005 allowed by the protocol. Now this is fixed and channel keys
5006 really are cell specific and the channel message delivery between
5007 routers comply with the protocol specification.
5009 * Fixed various commands in server to check also the global list
5010 for the channel entry and not just the local list. The affected
5011 file silcd/command.c.
5013 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5015 * Added assert()s to buffer formatting and unformatting routines
5016 to assert (if --enable-debug) when error occurs. Affected
5017 file: lib/silcutil/silcbuffmt.c.
5019 * Changed to auto-reconnect to check whether the remote host is
5020 router and register the re-connect timeout if it is. It used
5021 to check that whether we are normal server, but router must do
5022 auto-reconnect with another router as well. Affected file
5025 * Removed the [<key len>] option from CMODE command as the cipher
5026 name decides the key length, nowadays. See the defined ciphers
5027 from the protocol specification.
5029 * Added [<hmac>] option to the CMODE command to define the HMAC
5030 for the channel. Added SILC_CMODE_HMAC channel mode.
5032 * Added [<hmac>] option for the JOIN command so that user can
5033 select which HMAC is used to compute the MACs of the channel
5036 * Added Hmac field to the Channel Message Payload. The integrity
5037 of plaintext channel messages are now protected by computing
5038 MAC of the message and attaching the MAC to the payload. The
5039 MAC is encrypted. Now, it is clear that this causes some
5040 overhead to the size of the packet but rationale for this is that
5041 now the receiver can verify whether the channel message decrypted
5042 correctly and also when private keys are set for the channel the
5043 receiver can decrypt the packet with several keys and check from
5044 the MAC which key decrypted the message correctly.
5046 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5047 lib/silccrypt/silccipher.[ch].
5049 * Added silc_hash_len to return the digest length into the
5050 lib/silcrypt/silchash.[ch].
5052 * Rewrote parts of Silc Channel Payload interface in the
5053 lib/silccore/silcchannel.[ch]. The encode function now also
5054 encrypts the packet and parse function decrypts it.
5056 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * Fixed a minor formatting bug in the SKE's key material processing.
5059 It actually might have processed the keys wrong way resulting
5062 * Redefined the mandatory HMAC algorithms and added new algorithms.
5063 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5064 and hmac-md5 truncated to 96 bits. The mandatory is now
5065 hmac-sha1-96. Rest are optional (including the one that used
5066 to be mandatory). Rationale for this is that the truncated HMAC
5067 length is sufficient from security point of view and can actually
5068 make the attack against the HMAC harder. Also, the truncated
5069 HMAC causes less overhead to the packets. See the RFC2104 for
5072 * Added new [hmac] configuration section. The SKE used to use
5073 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5074 is of course wrong. The official names that must be proposed in
5075 the SKE are the ones defined in the protocol specification
5076 (hmac-sha1-96 for example). The user can configure any hmac
5077 using any hash function configured in the [hash] section. At
5078 least, the mandatory must be configured.
5080 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5082 * Added HMAC list to the SKE proposal list. It has now both
5083 hash algorithm list and HMAC list. This makes the protocol
5084 incompatible with previous versions. The SKE now seems to work
5085 the way it is supposed to work, for the first time actually.
5087 * Defined plain Hash algorithms to the protocol specification.
5090 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5092 * Implemented support for key agreement packets into the server.
5093 Added functions silc_server_key_agreement and
5094 silc_server_send_key_agreement. Other than these functions,
5095 server has nothing to do with this packet.
5097 * Added support for private message key packets into the server.
5098 Added functions silc_server_private_message_key and
5099 silc_server_send_private_message_key.
5103 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5104 called in the protocol's final callback instead in the END
5105 protocol state. This makes a little more sense and in the same
5106 time in client we can use the same protocol routines for normal
5107 key exchange and to key agreement packet handling as well.
5109 * Added to both client's and server's KE protocol context the
5110 SilcSKEKeyMaterial pointer to save the key material. We will
5111 bring the key material to the protocol's final callback by doing
5112 this. The final callback must free the key material.
5114 * Added SKE's packet_send callback into client's KE protocol
5115 context so that the caller can choose what packet sending function
5116 is used. This way we can use different packet sending when
5117 doing normal SKE when doing key agreement packet handling (in
5118 the key agreement packet handling we do not want to encrypt
5121 * Implemented the responder side of the key agreement routines
5122 in the client. The client can now bind to specified port and
5123 accept incoming key negotiation. The key material is passed
5124 to the application after the protocol is over.
5126 * Implemented the processing of incoming Key Agreement packet
5127 in the client. Added function silc_client_key_agreement to
5130 * Implemented the intiator side of the key agreement routines
5131 in the client. The client can now initiate key agreement with
5132 another remote client. The key material is passed to the
5133 application after the protocol is over.
5135 * Created client_keyagr.c to include all the key agreement
5138 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5139 SILC_TASK_CALLBACK except that it is not static.
5141 * Created client_notify.c and moved the Notify packet handling
5142 from the client.[ch] into that file.
5144 * Created client_prvmsg.c and moved all private message and
5145 private message key routines from the client.[ch] into that file.
5147 * Create client_channel.c and moved all channel message and
5148 channel private key routines from the client.[ch] into that file.
5150 * Changed silc_client_get_client_by_id_resolve to resolve with
5151 WHOIS command instead of IDENTIFY command, in the file
5152 lib/silclient/idlist.c.
5154 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5156 * Implemented the SKE's responder side to the Client library.
5158 * When FAILURE is received to the protocol do not trust it
5159 blindly. Register a timeout to wait whether the remote closes
5160 the connection as it should do it, only after that process the
5161 actual failure. This was changed to both client and server.
5163 * Added client_internal.h to include some of the structures
5164 there instead of client.h in lib/silcclient/.
5166 * Added function silc_task_unregister_by_callback to unregister
5167 timeouts by the callback function.
5169 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5171 * Some "Incomplete WHOIS info" errors has been appearing on the
5172 log files. Took away the entry->userinfo check from WHOIS
5173 reply sending. The entry->userinfo is now " " if client did not
5174 provide one. I thought this was fixed earlier but something
5175 is wrong still. Let's see if the error still appears.
5177 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5179 * Fixed a minor bug in the login when the channel key is
5180 re-generated in the server. It used to generate the key in
5181 wrong order and thus caused problems in the channel traffic.
5183 * Fixed a minor bug in channel key distsribution after
5184 KICK command. The key was not sent to the router even though
5187 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Added silc_ske_process_key_material_data as generic routine
5190 to process any key material as the SILC protocol dictates. The
5191 function is used by the actual SKE library but can be used by
5192 applications as well. This relates to the private message keys
5193 and the channel private keys since they must be processed the
5194 same way the normal SILC session keys. The protocol dictates
5195 this. Affected files: lib/silcske/silcske.[ch].
5197 Added also silc_ske_free_key_material to free the
5198 SilcSKEKeyMaterial structure.
5200 * Defined silc_cipher_set_key function to set the key for
5201 cipher without using the object's method function. The affected
5202 files: lib/silccrypt/silccipher.[ch].
5204 * Implemented silc silc_client_add_private_message_key,
5205 silc_client_add_private_message_key_ske,
5206 silc_client_del_private_message_key,
5207 silc_client_list_private_message_keys and
5208 silc_client_free_private_message_keys functions in the
5211 Added functions silc_client_send_private_message_key to send
5212 the Private Message Key payload and silc_client_private_message_key
5213 to handle incoming Private Message Key payload.
5215 * Added Cipher field to the Private Message Key payload to set
5216 the cipher to be used. If ignored, the default cipher defined
5217 in the SILC protocol (aes-256-cbc) is used.
5219 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5221 * Removed lib/silcclient/ops.h file.
5223 Redefined parts of the SILC Client Library API. Created new
5224 file silcapi.h that deprecates the ops.h file and defines the
5225 published Client Library API. Defined also private message key
5226 API and channel private key API into the file.
5228 This is the file that the application must include from the
5229 SILC Client Library. Other files need not be included by
5230 the application anymore.
5232 * Added new key_agreement client operation callback and also
5233 defined the Key Agreement library API for the application.
5235 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5237 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5238 is used by clients to request key negotiation between another
5239 client in the SILC network. If the negotiation is started it
5240 is performed using the SKE protocol. The result of the
5241 negotiation, the secret key material, can be used for example
5242 as private message key.
5244 Implemented the Key Agreement payload into the files
5245 lib/silccore/silauth.[ch].
5247 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Redefined ciphers for the SILC protocol. Added some new ciphers
5250 and defined the key lengths for the algorithms. Changed the
5251 code accordingly. The default key length is now 256 bits.
5253 * Fixed SKE key distribution function silc_ske_process_key_material
5254 when the key length is more than 128 bits. The default key
5255 length in SILC is now 256 bits.
5257 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5258 to indicate unsupported algorithm.
5260 * Renamed rijndael.c to aes.c and all functions as well.
5262 * Fixed a long standing channel key setting bug in client library.
5263 Weird that it has never surfaced before.
5265 * Fixed bug in channel deletion. If the entire channel is removed
5266 then it must also delete the references of the channel entry
5267 from the client's channel list as the client's channel entry and
5268 the channel's client entry share same memory.
5270 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5272 * Implemented CONNECT and SHUTDOWN commands in the client.
5274 * Implemented CLOSE command to the client.
5276 * Added the function silc_idlist_find_server_by_name into the
5277 files silcd/idlist.[ch].
5279 Added the function silc_idlist_find_server_by_conn into the
5280 files silcd/idlist.[ch].
5282 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5284 * DIE command was renamed to SHUTDOWN. Updated the both code
5287 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5288 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5290 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5293 * Added function silc_server_create_connection function to create
5294 connection to remote router. My server implementation actually
5295 does not allow router to connect to normal server (it expects
5296 that normal server always initiates the connection to the router)
5297 so the CONNECT command is only good for connecting to another
5300 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5303 or some other client was kicked from the channel.
5305 Implemented the handling of the notify type to both client
5308 Implemented silc_server_send_notify_kicked to send the KICKED
5309 notify. It is used to send it to the server's primary router.
5311 * Implemented the KICK command into server and client.
5313 * Added `query' argument to the silc_idlist_get_client function
5314 to indicate whether to query the client from server or not if
5317 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5318 to indicate that the client is not channel founder.
5322 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5324 * Removed the rng context from SilcPacketContext structure and
5325 changed that the packet routine uses the Global RNG API.
5327 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5329 * Added support for quit message that client can "leave" on the
5330 channel when it quits the SILC. It is ditributed inside the
5331 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5333 Added silc_server_free_client_data that will take the
5334 signoff message as argument.
5336 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5338 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5340 * Updated parts of the protocol specification to keep it up
5343 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5346 payloads in one packet.
5348 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5349 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5350 use now the new List flag.
5352 * Also deprecated the following packet types: REPLACE_ID,
5353 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5355 * Added list support for Notify packet in server.
5357 * Added silc_server_send_notify_channel_change to send the
5358 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5359 the silc_server_send_replace_id.
5361 * Added silc_server_send_notify_nick_change to send the
5362 NICK_CHANGE notify type. Deprecates the function
5363 silc_server_send_replace_id.
5365 * Added silc_server_send_notify_join to send the JOIN notify type.
5366 Deprecates the function silc_server_send_new_channel_user.
5368 * Added silc_server_send_notify_leave to send LEAVE notify type.
5369 Deprecates the function silc_server_send_remove_channel_user.
5371 * Added silc_server_send_notify_cmode and
5372 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5373 types. Deprecates the silc_server_send_set_mode function.
5375 * Added SERVER_SIGNOFF notify type to indicate that server has
5376 quit. This means that all clients on the channel from that
5377 server will drop. This can be also used when netsplit happens.
5379 Deprecated REMOVE_ID packet type since it is not needed anymore
5382 Added silc_server_send_notify_server_signoff to send the
5383 SERVER_SIGNOFF notify type. Deprecates the function
5384 silc_server_send_remove_id.
5386 Added also silc_server_send_notify_signoff to send the
5387 SIGNOFF notify type.
5389 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5390 SILC protocol from this day on. Changed the protocol
5391 specification as well.
5393 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5394 notify type. It is used between routers to notify about
5395 topic changes on a channel.
5397 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5400 * Partly updated the protocol specification to comply with the
5401 changes now made. It is still though a bit outdated.
5403 * The JOIN notify type now takes one extra argument <Channel ID>.
5404 The packet used to be destined to the channel but now the
5405 JOIN type may be sent as list thus it is impossible to
5406 destine it to any specific channel. By adding this argument
5407 it is again possible.
5409 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5411 * Added CREDITS file. The CHANGES and CREDITS file will appear
5412 in the distribution as well.
5414 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5417 types in the server's silcd/packet_receive.c.
5419 * Implemented CMODE and CUMODE to work in router environment.
5421 * Fixed minor encoding and decoding buglet from the
5422 lib/silccore/silcmode.c.
5424 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5427 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5429 * Changed all SilcConfigServer* and silc_config_server* to
5430 SilcServerConfig* and silc_server_config*, respectively.
5433 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5435 * Associated the ID (client or server ID) to the Authentication
5436 Payload to avoid any possibility of forging. Updated the
5437 protocol specification and the code accordingly.
5439 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5441 * The RSA key length is now save to the RsaKey context in the
5442 key generation process in lib/silccrypt/rsa.c. The key length
5443 is now used to figure out the maximum size of the block allowed
5444 to be encrypted/signed.
5446 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5447 is equivalent to the silc_mp_mp2bin but does not allocate any
5450 * Changed silc_mp_mp2bin API to take length argument. If it is
5451 non-zero then the buffer is allocated that large. If zero, then
5452 the size is approximated using silc_mp_sizeinbase, which however
5455 * Created Global RNG API which is global RNG that application can
5456 initialize. After initializing, any routine anywhere in the
5457 code (including library) can use RNG without allocating a new
5458 RNG object. This was done to allow this sort of use of the
5459 RNG in code that has no chance to allocate RNG object. All
5460 applications currently allocate this and many routines in the
5461 library use this. Affected file lib/silccrypt/silcrng.[ch].
5463 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5464 it to use the Global RNG API.
5466 * Defined Authentication Payload into protocol specification that
5467 is used during SILC session to authenticate entities. It is
5468 used for example by client to authenticate itself to the server
5469 to obtain server operator privileges.
5471 Implemented this payload into the lib/silccore/silcauth.[ch].
5472 Implemented also routines for public key based authentication
5473 as the new protocol specification dictates.
5475 Moved definitions of different authentication methods from
5476 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5478 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5479 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5480 silc_pkcs_verify_with_hash functions into the file
5481 lib/silccrypt/silcpkcs.[ch].
5483 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5485 * The client entry's userinfo pointer must be always valid.
5486 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5487 will fail since it requires the userinfo. Now, the userinfo
5488 is allocated as "" if actual userinfo does not exist. Actually,
5489 it must exist and it is totally Ok to drop client connections
5490 that does not announce the userinfo. However, we will make
5491 this workaround for now.
5493 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5494 to return the remote port by socket.
5496 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5498 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5499 SILC_SERVER_PENDING_EXEC and added an new macro
5500 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5501 data or when error occurs while processing the pending command.
5503 Added new argument `destructor' into silc_server_command_pending
5504 and to the SilcServerCommandPending object. This destructor is
5505 now called after calling the pending callback or if error occurs
5506 immediately. If error occurs the actual pending callback won't
5507 be called at all - only the destructor. The destructor may be
5508 NULL if destructor is not needed.
5510 All this applies for client library code as well. Similar
5511 changes were made there as well for the pending commands.
5513 In the client, the application must now allocate the
5514 SilcClientCommandContext with the silc_client_command_alloc
5517 * Added reference counter to the SilcServerCommandContext. Added
5518 function silc_server_command_alloc and silc_server_command_dup
5521 Same type of functions added to the client library for the same
5524 * Removed the cmd_ident from IDListData away since it is now
5525 global for all connections. It is the command identifier used
5526 in command sending and with pending commands. The affected file
5529 * Added reference counter to the SilcSocketConnection objecet to
5530 indicate the usage count of the object. The object won't be
5531 freed untill the reference counter hits zero. Currently only
5532 server uses this, and client ignores it. The client must be
5533 set to use this too later. The affected files are
5534 lib/silccore/silcsockconn.[ch]. Added also the function
5535 silc_socket_dup to increase the reference counter.
5537 This was mainly added because it is possible that the socket
5538 is removed underneath of pending command or other async
5539 operation. Now it won't be free'd and proper DISCONNECTING
5540 flags, etc. can be set to avoid sending data to connection that
5541 is not valid anymore.
5543 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5544 the connection. After that it sets SILC_SET_DISCONNECTED.
5545 It is, however, possible that the socket data is not still freed.
5546 The silc_server_packet_process now checks that data is not
5547 read or written to connection that is DISCONNECTED. The socket
5548 get's freed when the reference counter hits zero.
5550 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5552 * Changed the client operation API: channel_message operation's
5553 `sender' is now the client entry of the sender, not the nickname
5554 and the `channel' is the channel entry, not the channel name.
5556 In the private_message operation the `sender' is now also the
5557 client entry of the sender not the nickname.
5559 Affected file is lib/silcclient/ops.h and all applications
5560 using the client operations.
5562 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5564 * Moved the calling of ops->connect() from connect_to_server_final
5565 into receive_new_id functin since that is the point when the
5566 client is actually allowed to send traffic to network. The
5567 affected file is lib/silcclient/client.c.
5569 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5571 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5572 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5573 (if needs broadcasting) instead of broadcasting the packets one
5574 by one which would make a burst in the network traffic.
5576 * Added `broadcast' argument to the functions in silcd/server.[ch]
5577 silc_server_create_new_channel[_with_id] to indicate whether
5578 to send New Channel packet to primary router.
5580 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5582 * Added new function into the silcd/server.[ch] files:
5583 silc_server_create_new_channel_with_id to create new channel with
5584 already existing Channel ID.
5586 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5587 lib/silccore/silcpacket.h. This packet is used t send list of
5588 Set Mode payloads inside one packet. Server uses this to set
5589 the modes for the channels and clients on those channels, that it
5590 announced to the router when it connected to it. The protocol
5591 specification has been updated accordingly.
5593 * The silc_server_new_channel did not handle the packet coming
5594 from normal server as it normally does not send that. However,
5595 when it announces its channels it does send it. Implemented
5596 the support for that.
5598 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5599 into the file lib/silccore/id.h.
5601 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5603 * Fixed memory leaks in the functions silc_idlist_del_client,
5604 silc_idlist_del_channel and silc_idlist_del_server in the file
5605 silcd/idlist.c. All of those leaked like a sieve.
5607 * Fixed some small memory leaks in the client's function
5608 silc_client_notify_by_server.
5610 * Added functions into silcd/server.c: silc_server_announce_clients,
5611 silc_server_announce_channels and silc_server_announce_server.
5612 These functions are used by normal and router server to announce
5613 to its primary router about clients, channels and servers (when
5614 router) that we own. This is done after we've connected to the
5617 These functions effectively implements the following packet types:
5618 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5619 and SILC_PACKET_NEW_ID_LIST.
5621 * Added new functions into the silcd/packet_receive.[ch]:
5622 silc_server_new_id_list, silc_server_new_channel_list and
5623 silc_server_new_channel_user_list to handle the incoming
5624 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5626 * Added support of changing Channel ID in the function
5627 silc_server_replace_id. If the server that announces a channel
5628 to the router already exists in the router (with same name but
5629 with different Channel ID), router is responsible to send
5630 Replace ID packet to the server and force the server to change
5631 the Channel ID to the one router has.
5633 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5634 client that the Channel ID has been changed by the router. The
5635 normal server sends this to the client. Client must start using
5636 the new Channel ID as the channel's ID.
5638 Implemented handling of this new type into lib/silcclient/client.c
5639 into the function silc_client_notify_by_server.
5641 * Added new function silc_idlist_replace_channel_id into the files
5642 silcd/idlist.[ch] to replace the Channel ID.
5644 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5646 * Call silc_server_command_identify_check always when processing
5647 the IDENTIFY command in silcd/command.c
5649 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5651 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5652 send keepalive packets. The packet can be sent by clients,
5653 servers and routers.
5655 Added function silc_socket_set_heartbeat into the file
5656 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5657 If not set, the heartbeat is not performed. The actual
5658 heartbeat is implemented in the low level socket connection
5659 library. However, application is responsible of actually
5662 Added silc_server_send_heartbeat to send the actual heartbeat
5663 packet into silcd/packet_send.[ch]. Server now performs
5664 keepalive with all connections.
5666 * Added silc_task_get_first function into lib/silcutil/silctask.c
5667 to return the timeout task with shortest timeout. There was a bug
5668 in task unregistration that caused problems. TODO has been
5669 updated to include that task system must be rewritten.
5671 * The client library will now resolve the client information when
5672 receiving JOIN notify from server for client that we know but
5673 have incomplete information.
5675 * Rewrote parts of silc_server_remove_from_channels and
5676 silc_server_remove_from_one_channel as they did not remove the
5677 channel in some circumstances even though they should've.
5679 * Encryption problem encountered in server:
5681 The LEAVE command used to send the Channel Key packet to the
5682 router immediately after generating it. However, the code
5683 had earlier sent Remove Channel user packet but not immediately,
5684 ie. it was put to queue. The order of packets in the router
5685 was that Channel Key packet was first and Remove Channel User
5686 packet was second, even though they were encrypted in the
5687 reverse order. For this reason, MAC check failed. Now, this
5688 is fixed by not sending the Channel Key packet immediately but
5689 putting it to queue. However, this is more fundamental problem:
5690 packets that are in queue should actually not be encrypted
5691 because packets that are sent immediately gets encrypted
5692 actually with wrong IV (and thus MAC check fails). So, packets
5693 that are in queue should be encrypted when they are sent to
5694 the wire and not when they put to the queue.
5696 However, the problem is that the current system has not been
5697 designed to work that way. Instead, the packet is encrypted
5698 as soon as possible and left to the queue. The queue is then
5699 just purged into wire. There won't be any fixes for this
5700 any time soon. So, the current semantic for packet sending
5703 o If you send packet to remote host and do not force the send
5704 (the packet will be in queue) then all subsequent packets to the
5705 same remote host must also be put to the queue. Only after the
5706 queue has been purged is it safe again to force the packet
5709 o If you send all packets immediately then it safe to send
5710 any of subsequent packets through the queue, however, after
5711 the first packet is put to queue then any subsequent packets
5712 must also be put to the queue.
5714 Follow these rules and everything works fine.
5716 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5718 * Added new function silc_server_remove_clients_by_server to
5719 remove all client entries from ID list when the server connection
5720 is lost. In this case it is also important to invalidate all
5721 client entires as they hold the invalid server entry. This
5722 fixes fatal bug when server has lost connection and will reconnect
5725 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5727 * Made some sanity checks to silc_server_daemonise like to check
5728 whether the requested user and group actually exists.
5730 * Added sanity check to SKE's silc_ske_responder_finish to check
5731 that the public and private key actually is valid.
5733 * Invalidate the client's nickname when receiving Replace ID
5734 packet and the Client ID is being replaced. This means that the
5735 server will query the nickname if someone needs it (client)
5738 * Sort the ID Cache in client library when the ID Cache data
5739 has changed (needs sorting).
5741 * Do not allow for SILC client to create several connections to
5742 several servers. The client does not support windows right now
5743 and generating multiple connections causes weird behaviour.
5745 Irssi-silc client does support windows and can handle several
5746 connections without problems, see: www.irssi.org and SILC plugin.
5748 * Fixed some places where client was added to the IDList. The
5749 rule of thumb is following (in order to get everything right):
5750 If the client is directly connected local client then the
5751 `connection' argument must be set and `router' argument must be
5752 NULL to silc_idlist_add_client function. If the client is not
5753 directly connected client then the `router' argument must
5754 bet set and the `connection' argument must be NULL to the
5755 silc_idlist_add_client function.
5757 * The funtion silc_server_packet_send_local_channel actually did
5758 not check whether the client was locally connected or not. It
5759 does that now. Fixed a bug related to LEAVE command.
5761 * Fixed Remove Channel User payload parsing bug in server's
5762 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5764 * The server's silc_server_save_channel_key now checks also the
5765 global ID list for the channel as it might not be in the local
5766 list. Fixed a bug related to LEAVE command.
5768 * Is this the end of the [<unknown>] buglet that has been lurking
5769 around for a long time? A little for loop fix in server's
5770 silc_server_command_whois_parse that is used by both IDENTIFY
5771 and WHOIS command. At least, this was a clear bug and a cause
5772 of one type of [<unknown>] buglet.
5774 * WHOIS and IDENTIFY commands call the function
5775 silc_server_command_[whois/identify]_check function even if
5776 we are not router server.
5778 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5780 * Added --with-gmp configuration option. If set the GMP
5781 is always compiled in the SILC source tree. If not set then
5782 it is checked whether the system has the GMP3 installed. If
5783 it has then the GMP won't be compiled (the system's headers
5784 and library is used), if it doesn't have it then the GMP is
5785 compiled in the SILC source tree.
5787 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5789 * Changed RSA private exponent generation to what PKCS #1
5790 suggests. We try to find the smallest possible d by doing
5791 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5792 not security fix but optimization.
5794 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5796 * Added new config entry [Identity] to fork the server and run
5797 it as specific user and group. A patch from Bostik.
5799 * Imported Dotconf configuration library into lib/dotconf.
5800 This will be used to create the SILC configuration files later.
5801 It will appear in the distsribution after this commit.
5803 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5805 * A big code auditing weekend happening. Auditing code for
5806 obvious mistakes, bugs and errors. Also, removing any code
5809 Removed files for being obsolete:
5811 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5812 inline in the file lib/silcutil/silcbuffer.h)
5814 o lib/silcutil/silcbufutil.c (the header has inline versions)
5816 Changed code to fix possible error conditions:
5818 o The buffer formatting routines now check that the destination
5819 buffer really has enough space to add the data. This applies for
5820 both buffer formatting and unformatting
5821 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5822 unformatting was changed to accomodate following rules:
5823 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5824 sent to the function while XXX_*STRING will not allocate or copy
5825 the data into the buffer. Instead it sets the pointer from the
5826 buffer into the pointer sent as argument (XXX_*STRING used to
5827 require that the pointer must be allocated already). This change
5828 makes this whole thing a bit more consistent and more optimized
5829 (note that the data returned in the unformatting with XXX_*STRING
5830 must not be freed now). The routines return now -1 on error.
5832 o Tried to find all code that use buffer_format and buffer_unformat
5833 and added return value checking to prevent formatting and
5834 especially unformatting errors and possible subsequent fatal
5837 o Changed ske->x and ske->KEY to mallocated pointers in
5838 lib/silcske/silcske.h. Fixed possible data and memory leak.
5840 o Added return value checking to all *_parse* functions. Fixed
5841 many memory leaks as well.
5843 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5844 so that buffer overflows would not happen. All code now also
5845 checks the return value as it can fail.
5847 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * Added reconnection support to server if the normal server looses
5850 its connection to the router (for example if router is rebooted).
5851 The server performs normal reconnection strategy implemented
5852 to the server. Affected file silcd/server.c.
5854 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5856 * Added new packet type SILC_PACKET_SET_MODE that is used to
5857 distribute the information about changed modes (for clients,
5858 channels and clients channel modes) to all routers in the
5859 network. Updated the protocol specification accordingly.
5861 Added functions into silcd/packet_send.c and
5862 silcd/packet_receive.c: silc_server_send_set_mode,
5863 silc_server_set_mode.
5865 Added new files silcmode.[ch] into lib/silccore that implements
5866 the encoding and decoding of Set Mode Payload. Added new type
5867 SilcSetModePayload. Moved the definitions of different modes
5868 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5870 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5872 * Oops, a little mistake in server's connection authentication
5873 protocol. The protocol is not ended with FAILURE but with
5874 SUCCESS if the authentication is Ok. :) Affected file is
5877 * Implemented NICK_CHANGE notify handling in server in the file
5878 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5879 the local clients on the channel. After the changing nickname
5880 in router environment snhould work and the [<unknown>] nickname
5881 should appear no more.
5883 The silc_server_replace_id function that receives the Replace ID
5884 payload now sends the NICK_CHANGE notify type also in the file
5885 silcd/packet_receive.c
5887 * Changed WHOIS and IDENTIFY command to support the maximum amount
5888 of arguments defined in protocol specs (3328 arguments). This
5889 fixed a bug that caused problems when there were more than three
5892 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5894 * Added extra parameter, command identifier, to the
5895 silc_client_send_command so that explicit command identifier
5898 Changed that ID list routines uses specific command identifier
5899 when sending WHOIS/IDENTIFY requests to the server so that they
5900 can be identified when the reply comes back.
5902 Affected files lib/silcclient/command.[ch],
5903 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5905 * Added `sender' argument to silc_server_packet_send_to_channel
5906 to indicaet the sender who originally sent the packet to us
5907 that we are now re-sending. Ignored if NULL. Affected file
5908 silcd/packet_send.[ch].
5910 * Added some server statistics support in silcd/server_internal.h
5911 SilcServerStatistics structure and around the server code. Also
5912 send some nice statistics information when client is connecting
5915 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5917 * Fixed channel ID decoding in server's JOIN command reply in
5918 silcd/command_reply.c
5920 * Fixed braodcasting of replace ID payload to not to send it if
5921 we are standalone server in silcd/packet_receive.c.
5923 * Fixed all channel message sending routines to not to send
5924 packets to clients that has router set, since they are routed
5925 separately in the same function earlier. Affects file
5926 silcd/packet_send.c and all channel packet sending functions.
5928 * In USERS reply, res_argv[i] are not allocated, the table
5929 is allocated. Thus changed that free the table, not its
5932 * In server's whois_check and identify_check if the client is
5933 locally connected do not send any WHOIS commands - they are not
5936 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5938 * Fixed some minor bugs in client when sending WHOIS command. The
5939 arguments was in wrong order.
5941 * Removed statis function add_to_channel from server in
5942 silcd/command.c that was previously used with the joining but
5945 * Tested USERS command in router environment successfully with two
5946 routers, two servers and two clients.
5948 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5950 * Reorganized the USERS command and command reply in client library
5951 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5952 When the command is given by user we register a pending command
5953 callback that will reprocess the command after the reply has been
5954 received from the server. When reprocessing the packet we then
5955 display the information. Thus, the USERS information is displayed
5956 now in the command callback instead of in the command reply
5957 callback. The processing of the command is same as previously
5958 when server has sent the command reply in the JOINing process.
5960 * Added to USERS command in silcd/command_reply.c to join the client,
5961 we didn't use to know about, to the channel after we've created
5962 a client entry for it. Also, for clienet we did know already still
5963 check whether it is on the channel or not and add it if not.
5965 * Removed silc_server_command_join_notify as the function and its
5968 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5970 * Changed the client's pending command handling to the same as the
5971 server's pending command handling. It is also now possible to
5972 execute command reply functions from other command reply
5973 function as the function callbacks for commands and command
5974 replies are one and same. The pending commands are not static
5975 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5976 in client connection context. Thus, pending commands are server
5977 connection specific as it is convenient.
5979 Changed the function silc_client_command_pending and
5980 silc_client_command_pending_del and added new function
5981 silc_client_command_pending_check. Removed the
5982 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5985 * Added cmd_ident, current command identifier, to the client
5986 connection context in lib/silcclient/client.h to keep track on
5987 command identifiers used in command sending. Client's command reply
5988 function handling now supports the mandatory command identifiers.
5990 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5991 funtions in client to fully support pending command callbacks.
5993 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5994 as one of the arguments to the application in the command reply
5997 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5998 before first releasing SILC but came back. Now it is removed again
5999 and should come back nomore. The FORWARDED flag was used only
6000 by the JOINing procedure by forwarding the command packet to router.
6001 Now, the JOINing procedure has been changed to more generic (due
6002 to various router environment issues) and FORWARDED is not needed
6003 anymore for anything. The protocol specification is yet to be
6006 Now, removed silc_server_packet_forward from server and the flag
6007 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6009 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6011 * Renamed NAMES command to USERS command. The NAMES was named that
6012 due to historical reasons. Now it is renamed. Also, rewrote
6013 parts of the USERS command. The nickname list is not sent anymore
6014 by the server. Only Client ID and mode lists are sent in the USERS
6015 command. Changed this also to the protocol specification.
6017 The client now resolves the names and stuff after it receives
6018 the USERS list from the server when joining to the channel.
6020 * WHOIS and IDENTIFY commands has been changed to support multiple
6021 Client ID's per command. One can now search for multiple users
6022 in the network by sending only one WHOIS or IDENTIFY command.
6023 Changed the code and the protocol specifications.
6025 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6026 uses silc_server_command_whois_parse to parse the request. */
6028 * If normal server, do not parse the WHOIS and IDENTIFY requests
6029 before sending it to the router. Saves some time.
6031 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6033 * Fixed JOIN command on client library. Wrong number of arguments
6034 used to crash the client.
6036 * Added silc_server_channel_has_global function to check whether
6037 channel has global users or not.
6039 * Added silc_server_channel_has_local function to check whether channel
6040 has locally connected clients on the channel.
6042 * The silc_server_remove_from_one_channel now checks whether the
6043 channel has global users or not after given client was removed from
6044 the channel. It also checks whether the channel has local clients
6045 on the channel anymore. If it does not have then the channel entry
6046 is removed as it is not needed anymore.
6048 * The silc_server_notify now checks on JOIN notify whether the joining
6049 client is one of locally connected or global. If it is global then
6050 the channel has now global users on the channel and that is marked
6051 to the channel entry. Also, it now saves the global client to
6052 global list who is joining and JOINs it to the channel. This is
6053 for normal server, that is.
6055 Changed silc_server_send_notify_on_channel,
6056 silc_server_packet_relay_to_channel and
6057 silc_server_packet_send_to_channel check if we are normal server
6058 and client has router set (ie. global client) do not send the
6059 message to that client, as it is already routed to our router.
6061 * Implemented LEAVE notify type handling in silc_server_notify
6064 * Tested LEAVE command in router environment successfully. Tested
6065 with two routers, two servers and two clients.
6069 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6071 * Implemented SIGNOFF notify type handling in silc_server_notify
6074 * silc_server_remove_id now removes the client entry from all channels
6075 it has joined and thusly sends SIGNOFF notify type.
6077 * Rewrote the NAMES list generation in server by removing two excess
6078 loops. The lists are created now inside one loop.
6080 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6082 * silc_server_remove_channel_user checks now also global list
6083 for channel and client.
6085 * silc_server_new_channel_user checks now both local and global
6086 list for channel and client. Fixed a bug in client id decoding.
6087 Used to decode wrong buffer.
6089 * silc_server_channel_message checks now both local and global
6090 list for channel entry.
6092 * Tested channel joining (hence JOIN) in router environment
6093 successfully. Tested with two routers, two servers and two
6096 * Tested channel message sending in router environment successfully.
6098 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6100 * Added silc_server_save_channel_key into server.[ch] to save the
6101 received channel key in Channel Key payload processing. It is
6102 also used in JOIN command reply handling.
6104 Equivalent function silc_client_save_channel_key added into
6105 client.[ch] into client library.
6107 * Changed JOIN command reply to send information whether the channel
6108 was created or not (is existing already) and the channel key
6109 payload. Changed protocol specs accordingly.
6111 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6112 the request was sent by ID and not by nickname. Crashed on
6115 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6117 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6118 now correctly save the received data.
6120 * silc_server_free_sock_user_data now notifies routers in the
6121 network about entities leaving the network.
6123 At the same time implemented functions silc_server_remove_id
6124 and silc_server_send_remove_id to receive and send REMOVE_ID
6125 packets. The packet is used to notify routers in the network
6126 about leaving entities. The ID removed will become invalid in
6129 * Added function silc_idlist_del_server into server. Removes and
6130 free's server entry from ID list.
6132 * silc_server_private_message function now checks, if we are router,
6133 that the destination ID really is valid ID, naturally.
6135 * In router when NEW_ID packet is received (for new client) the
6136 hash of the Client ID is saved in the ID Cache but the
6137 client->nickname is set to NULL, instead of putting the hash
6140 IDENTIFY command now also checks that client->nickname must be
6141 valid. If it is not if will request the data from the server who
6142 owns the client. Added new function
6143 silc_server_command_identify_check.
6145 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6146 to set the command to already allocated Command Payload.
6148 * Tested private message sending in router environment with two
6149 routers, two servers and two clients. Fixed minor bugs and now
6152 * Fixed segfault from client's NAMES command. Used to crash if
6155 * Forwarded packets must not be routed even if it is not destined
6156 to the receiver. Changed server code comply with this.
6158 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6160 * Added `require_reverse_mapping' boolean value to ServerParams
6161 structure. If TRUE (not default) the server will require that
6162 the connecting host has fully qualified domain name.
6164 If the reverse mapping is not required and hostname could not be
6165 found the IP address is used as hostname.
6167 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6169 * Implemented version string checking to both client and server.
6170 The check is incomplete currently due to the abnormal version
6171 strings used in development version of SILC.
6173 * Changed all command functions in server to use the new
6176 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6178 * Changed char *data to unsigned char *data in ID Cache system to
6179 support binary data as ID Cache data. Changed code to support
6180 binary data in lib/silccore/idcache.c.
6182 * Renamed silc_server_packet_relay_command_reply to
6183 silc_server_command_reply as it is normal packet receiving
6184 function. Rewrote the function to accept command replys for
6185 servers and not only for clients.
6187 * Mark remote router always as registered server if we are connecting
6188 to it. Otherwise, commands sent by the router to us are ignored.
6190 * All ID List find routines now returns the ID Cache Entry pointer
6191 as well if requested.
6193 * WHOIS command works now in router environment, tested with two
6194 routers, two servers and two clients.
6196 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6197 in router environment (as it is almost equivalent to WHOIS) but
6198 hasn't been tested thoroughly. Added new functions:
6200 silc_server_command_identify_parse
6201 silc_server_command_identify_send_reply
6202 silc_server_command_identify_from_client
6203 silc_server_command_identify_from_server
6205 * Disabled route cache adding because adding two different ID's with
6206 same IP replaces the old cache entry thus giving wrong route.
6207 The entry->router->connection is always the fastest route anyway
6208 so route cache may not be needed. Of course, new routes maybe
6209 established after receiving the ID when the entry->router->connection
6210 might not be anymore the most optimal.
6212 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6214 * Add route cache for received ID for fast routing.
6216 * Added silc_server_packet_route to route received packet on router
6217 that is not destined to us.
6219 * Renamed silc_server_get_route to silc_server_route_get.
6221 * Added id_string and id_string_len fields into SilcServer to
6222 include encoded ServerID for fast comparing without excess
6223 encoding of the ID's.
6225 * Cleaned up WHOIS command on server side. Added following static
6228 silc_server_command_whois_parse
6229 silc_server_command_whois_check
6230 silc_server_command_whois_send_reply
6231 silc_server_command_whois_from_client
6232 silc_server_command_whois_from_server
6234 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6235 arguments in command replies. All command functions should be
6236 updated to use this macro.
6238 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6240 * Minor typo fixes on command reply handling on server.
6242 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6244 * Added silc_server_command_add_to_channel internal routine to add
6245 the client to the channel after router has created the channel and
6246 sent command reply to the server.
6248 * Added generic silc_server_send_command to send any command from
6251 * Use static buffer with ID rendering instead of duplicating data.
6253 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6255 * Fixed a channel user mode bug when joining to a channel server gave
6256 everybody channel founder rights, oops.
6258 * We mark ourselves as the router of the incoming server connection
6259 if we are router ourselves. This way we can check in some packet
6260 sending functions whether it is locally connected server. For
6261 incoming router connections we put NULL.
6263 * For router sending packets locally means now always sending the
6264 packet cell wide; to local clients and local servers. For normal
6265 server sending packet locally means sending it to only local
6268 * Fixed the JOIN command to really work in router environment. If the
6269 channel is created it is always created by the router. Router is
6270 also responsible of making the initial joining to the channel,
6271 sending JOIN notify to the sending server and distributing
6272 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6273 does not exist server doesn't do anything else but forward the
6274 command to the router which performs everything.
6276 * Added silc_server_send_channel_key function to send the Channel Key
6279 * Added silc_server_create_channel_key to create new channel key. The
6280 channel key is now re-generated everytime someone joins or leaves
6281 a channel, as protocol dictates. Note: channel->key_len is the
6284 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6286 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6287 packet_receive.[ch] to separate packet sending and receiving
6288 routines. The server.[ch] now includes everything else including
6289 actual packet processing (writing and reading data) and other
6292 Renamed silc_server_private_message_send_internal to
6293 silc_server_send_private_message. The routine is still though
6294 used only to relay private messages as server does not send
6295 private messages itself.
6297 Renamed silc_server_new_channel to silc_server_create_new_channel
6298 and added new function sicl_server_new_channel that handles the
6299 incoming New Channel packet. Added also new sending function
6300 silc_server_send_new_channel to send New Channel Payload.
6302 * Added new function silc_server_notify to process incoming notify
6303 packet to the server/router. Server may then relay the notify
6304 to clients if needed.
6306 * Added new function silc_server_new_channel_user to process incoming
6307 New Channel User packet. Router will redistribute the packet and
6308 send JOIN notify to its local clients and locally connected servers
6309 if needed. Normal server will send JOIN notify to its local client
6310 on same channel when received this packet. Added also corresponding
6311 sending function silc_server_send_new_channel_user to sent the
6314 * Added boolean route argument to send_notif_to_channel and
6315 packet_send_to_channel functions to attempt to route the packet
6316 if it is TRUE and send only locally if it is FALSE.
6318 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6320 * silc_server_replace_id now broadcasts the received replace ID
6321 packet if it is not broadcast packet already. The router must
6322 broadcast to inform other routers about changed ID.
6324 * Added backpointer to server's router into SilcServer context in
6325 silcd/server_internal.h.
6327 * Fixed silc_server_packet_broadcast to send correct broadcast
6330 * The channel key is now distributed to the local client as soon
6331 as it is received from the router (in router environment) so that
6332 no other packet may be sent for the channel until client has
6335 * silc_server_remove_channel_user now broadcasts the received
6336 Remove Channel User packet if it is not broadcast packet already.
6337 The router must broadcast to inform other routers about removed
6340 * Added users field into SilcPacketContext that is a reference count
6341 of the context. One can increase the reference count by calling
6342 silc_packet_context_dup which is now changed to just increase the
6343 reference count instead of duplicating the data. The reference
6344 count is decresed by calling silc_packet_context_free that will
6345 free the data after the reference count hits zero.
6347 For now on the packet context and everything allocated into it
6348 (including the raw packet from network) must be freed by calling
6349 the new silc_packet_context_free function. Added also new function
6350 silc_packet_context_alloc that must be used now to allocate the
6351 context. This also means that if a routine is asynchronous from
6352 silc_[client/server]_packet_parse_type the packet context must
6353 be duplicated by calling silc_packet_context_dup. Otherwise it
6354 gets free'd after silc_[client/server]_packet_parse_type returns.
6355 Also, one must remember that if packet is duplicated then its
6356 reference count must be decresed by calling the free function as
6357 many times as it was duplicated.
6359 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6360 from both client and server.
6362 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6364 * Made joining to a channel working in router environment.
6366 * Cleaned up JOIN command on server side and create function
6367 silc_server_command_join_channel internal routine to make the
6370 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6372 * Changed silc_command_pending list to SilcDList. Also, added
6373 `ident' field to SilcServerCommandPending structure to identify
6374 the reply and to call correct callback.
6376 Added silc_server_command_pending_check function to replace the
6377 corresnponding macro. The silc_command_pending list is not
6380 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6381 to set identifier to previously allocated Command Payload. It
6382 is used to set identifier for command when resending Command
6385 * Added silc_command_payload_encode_payload to encode Command
6386 Payload buffer from SilcCommandPayload structure.
6388 * Added silc_argument_payload_encode_payload to encode Argument
6389 payload buffer from SilcArgumentPayload structure.
6391 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6393 * Changed WHOIS command to support router connection on server side.
6394 The whois request is always sent to router unless the server is
6395 standalone server. After server has received the reply from the
6396 router will it send the reply to the client.
6398 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6399 broadcast received broadcast packet. The function is used only
6400 by router. The broadcast packet is always sent to the router's
6403 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6404 render given ID to printable string, for log files for example.
6406 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6408 * Made basic router to router connections working. At least they
6409 can now connect to each other but nothing really works the way
6410 they are supposed - yet.
6412 * Added new initiator token to RouterConnection configuration
6413 file in silcd/serverconfig.[ch]. It is used to tell whether we
6414 are the initiator to the remote router or whether we'll expect
6415 the other end to connect.
6417 * Moved registering of listener task to silc_server_init, hence
6418 the server starts listenning as soon as it is run, even if it
6419 does not have connections to other routers. Let's see how well
6422 * Changed default connection retry timeouts for more suitable in
6425 * Removed cipher and such arguments from silc_idlist_add_client
6426 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6427 Added new function silc_idlist_add_data to add the keys and stuff
6430 * Added SilcIDListData structure and added it to SilcClientEntry
6431 and SilcServerEntry as their first field in the structure. This
6432 way we can explicitly cast the ID entries to the SilcIDListData
6433 structure and get common data for the entries. In past, we had
6434 to first check what type of connection it is and then cast it to
6435 correct ID entry type. Now, we can directly cast the opaque
6436 pointer to the SilcIDListData (no matter what ID entry it actually
6437 is) and get the data needed.
6439 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6441 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6442 in some circumstances even if threre were timeout tasks, though not
6443 IO tasks, but tasks anyway. Now fixed.
6445 * Defined SilcServerConnection structure to hold connection specific
6446 stuff about directly connected servers and routers. The definition
6447 is currently in silcd/server_internal.h. I thought about having
6448 a bit more important role fro this struct but for now it is used
6449 only when connecting to other server (or router actually).
6451 * Added connecting retry support in server when connecting to
6452 router(s). The retry feature implement exponential backoff
6453 algorithm. Also, added SilcServerParams structure to hold default
6454 parameters for server. For now, it include these retry settings
6455 and are hard coded. After server is moded to be as Silc Server
6456 Library this structure will be more important.
6458 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6460 * Changed client librarys channel->clients table to SilcList and
6461 changed code accordingly.
6463 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6465 * Changed client's channel table to SilcList and changed code
6466 accordingly. Also changed SilcChannelClientEntry to include back-
6467 pointer to the channel so that client entry can use that structure
6468 as list as well and we have fast cross-reference to the channel.
6469 This change dramatically decreased the complexity of channel
6470 handling with client entry and vice versa (removed one extra
6471 loop when searching for channel entry from many functions).
6473 * Changed server->sim from table to SilcDList and changed code
6476 * NAMES command can now be used from user interface. It will show
6477 the user list on the channel, neatly.
6479 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6480 Code now saves realname of the user if it becomes available.
6482 * Renamed configure.in to configure.in.pre and made ./prepare
6483 script to automatically add correct version string to
6484 configure.in which it creates from configure.in.pre.
6486 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6488 * NAMES command reply now shows users mode with the nickname when
6491 * Moved silc_client_ch[u]mode[_char] functions from
6492 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6493 place sucks, they are utility functions and should be in some
6496 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6498 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6501 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6505 * Added TRQ (efficient deque and list library) into lib/trq. This is
6506 a very good list library that is currently used in the SILC. Defined
6507 SilcList API over the library because I didn't like the API very
6508 much. See lib/trq/silclist.h for the API and examples of how to
6509 use the API. Fixed various places in the code to use the new
6510 SilcList API. The SilcList is meant for lists that has a structure
6511 already defined as a list. It is not suitable to add just some
6512 context to the list (in TRQ, the context is the list actually).
6514 So, I defined SilcDList that can be used for the purpose where
6515 predefined list structure does not exit. This can be used as
6516 such list. Now some context just can be added to the SilcDList.
6517 Currently this list is not used in the SILC just yet, though there
6518 are a lot places where this can replace dynamically allocated
6519 tables and I will fix these places, later, to use SilcDList.
6520 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6521 and use TRQ internally).
6523 Also fixed some annoying warning messages that the original TRQ
6524 code generated. Also minor changes to TRQ's Makefile.in.
6526 * Added support for querying by Client ID to both WHOIS and
6527 IDENTIFY commands into server, as required by the protocol.
6529 * Removed method function pointers from SilcBuffer structure. They
6530 weren't used to anything and just increased the context size for
6531 no good reason. This change also made silc_buffer_alloc and
6532 silc_buffer_free functions inline functions.
6534 * Disabled command flooding detection support until it's fixed so
6535 that it accepts commands in but does not execute them more than once
6538 * Added silc_net_localhost(), to return local hostname, into
6539 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6540 that must be initialized before calling silc_client_init.
6542 * Added new function: silc_server_send_notify_on_channels to send
6543 notify messages to all channels client has joined. It is assured
6544 that the message is sent only once per client.
6546 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6547 lib/silcutil/silcutil.[ch] as silc_format function. The new
6548 function is generic and is used by server as well, not only by
6549 the logging routines.
6551 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6552 the provided version string was not acceptable. Added new function:
6553 silc_ske_check_version into lib/silcske/silcske.h. The function
6554 must be implemented by the application (client or server) and it
6555 does not reside in the SKE library. The function checks the version
6556 string remote end sent.
6558 * Added back pointers (to opaque context and to SilcSocketConnection)
6559 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6561 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6562 duplicate packet context structure.
6564 * Changed `notify' client operation to send same arguments as client
6565 receives from server except for ID's. ID's are mapped to correct
6566 ID entry and that is returned. Also, if channel entry is not sent
6567 by server but the notify is for channel the channel entry is sent
6568 to application (otherwise application doesn't know that it is for
6569 channel (library gets it from packet's Destination ID)).
6571 * Added silc_client_remove_from_channels into client library to
6572 remove a client from all channels it has joined to. Used when
6573 received SIGNOFF notify from server. Added also new function
6574 silc_client_replace_from_channels to replace old ID entry with
6575 new ID entry on all channels. Used when received NICK_CHANGE
6578 * Fixed ID Cache list handling in silc_idlist_get_client in
6579 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6580 to get (or query) client by ID.
6582 * Updated TODO list.
6584 * Added connection authentication status message defined by the
6585 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6586 support for these into the code in client and server side.
6588 * Added generic function silc_client_send_command to send any command
6589 with variable argument list. Application should use this function
6590 to send commands if the command functions provided by the library
6591 does not suite for the application's user interface needs.
6593 * Added new `failure' client operation. Application is notified about
6594 received failure packet if client is executing a protocol. In this
6595 case the protocol's execution has failed.
6597 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6598 is required by the protocol.
6600 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6601 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6604 * Added status flag to SilcSKE object to indicate realtime status
6605 of the SKE protocol.
6607 * Application receives now exactly same command reply arguments as
6608 the library receives from server. However, if ID is received the
6609 corresponding ID entry is returned to the application (eg. Client
6610 ID is mapped to correct SilcClientEntry entry and that is returned).
6611 Changed command_reply client operation due to this change.
6613 * Changed all ID's in commands and in command replys as ID Payloads.
6614 Change affected both client and server side codes.
6616 All ID's sent in SILC network (with execption of ID's in SILC
6617 Packet header) are sent in ID Payload to support variable length
6620 * Server now notifies nick changes and notifies all clients on
6621 the channels about the new nickname (about the new Client ID,
6624 * Implemented CMODE command to change channel modes. Supports all
6625 channel modes defined by the protocol specs except ban and invite
6626 lists. (Also, private channel key mode is supported but support for
6627 setting private channel key in client is missing, thus, this mode
6628 has no effect on client side (except that server requires that the
6629 client uses private channel key and normal channel traffic does not
6632 Also, invite mode works per se, but INVITE command does not work
6633 yet correctly, so you can set channel as invite only channel but
6634 inviting clients to the channel does not work (it is yet to be
6635 thought what's the best way to do it).
6637 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6638 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6639 Implemented CUMODE command to change user's mode on the channel.
6640 Supports all modes defined by the protocol specs.
6642 * Added NAMES command reply to return users modes on the channel.
6644 * Removed unnecessary and slow ciphers from lib/silccrypt.
6646 * Set SO_KEEPALIVE option to connection sockets by default.
6648 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6650 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6651 redefined the Notify Payload into protocol specs.
6653 * Added silc_id_payload_parse_id to get ID directly from raw
6656 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6658 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6659 accept searching by Client ID as well.
6661 * Added support for LEAVE and SIGNOFF notify types in client library.
6663 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6664 to parse ID Payload from raw data.
6666 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6668 * Added flags parameter into silc_ske_assemble_security_properties
6669 function in lib/silcske/silcske.[ch].
6671 * Changed notify client operation to fit better for notify messages
6672 sent by server. The notify payload received from server is now
6673 passed to the application (after parsing it to SilcNotifyPayload).
6674 It is application's responsibility to retrieve the arguments
6675 from the payload and show the message the way it wants. The message
6676 sent by server is implementation specific.
6678 * Changed public keys to comply with the protocol specification.
6679 Old public keys are not supported anymore and are not compatible.
6681 * Removed nickname from Channel Payload as the latest draft removed
6682 it. The client must resolve the nickname from the NAMES command
6683 reply received when it joined the channel.
6685 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6687 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6689 * Fixed some errors in protocol specification drafts.
6691 * Created lib/silccore/silcnotify.c to implement Notify Payload
6692 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6693 generic payloads described by protocol specifications. The file
6694 includes implementations for ID Payload and Argument Payload.
6696 * Changed Command Payload implementation to use the new Argument
6697 Payload. Changed command_xxxx_payload to command_payload_xxxx
6698 to comply with SILC coding conventions.
6700 * Added suppport for Argument Payload handling in Notify Payload
6701 implementation as protocol requires it. Added the new support
6702 into server and client lib as well.
6704 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6706 * Added support for multiple nicknames on same channel. [n] is
6707 added locally to the nickname if there are more than one same
6708 nicknames on the channel.
6710 * Server now sends all nicknames that matched WHOIS request.
6711 Client also shows the list received from server.
6713 * Added TOPIC command to client side. User can now set and show
6714 current topic on channel.
6716 * Added MOTD command to client and server. Also, server sends the
6717 motd when client connects to the server.
6719 * Changed version strings to comply ISO 8601.
6721 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6723 * Fixed protocol error handling in client library. It should now
6724 cope even if the SKE fails for some reason.
6726 * Made new protocol specification drafts for submitting to IETF.
6728 * Implemented TOPIC command to server in silcd/command.c.
6730 * Added two new notify types into lib/silccore/silcnotify.h:
6731 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6732 notify nickname change and topic setting/change on a channel.
6734 * API change of command_reply operation in client library. The
6735 application gets now the status type received from server as well.
6737 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6739 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6741 * Cras fixed and optimized the packet handling even further and
6742 it should work now. Minor change to the prototype of function
6743 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6745 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6747 * Added new function into lib/silcutil/silcschedule.[ch]:
6748 silc_schedule_with_fd to select() a specified fd. The function
6749 returns after timeout expires or data arrives or goes. The
6750 function is used by packet routines to wait that all data is
6751 received from network.
6753 * Fixed data reading from network in lib/silccore/silcpacket.c.
6754 The code now assures that all data is read from the fd and then
6755 continues packet processing. This was a bug fix since the code
6756 used to drop some data in some circumstances.
6758 * Added new function into lib/silcclient/client.[ch]:
6759 silc_client_start_key_exchange to start key exchange after
6760 connection has been established to server. The code internally
6761 now uses this funtion but its main purpose was to provide it
6762 for applications that perform their own connecting. After
6763 application has created a connection it merely calls this
6764 function to start the key exchange between client and server.
6765 The library takes care of everything else after that.
6767 Updated also lib/silcclient/README to explain the usage of
6770 * Do not send to application information that connection has
6771 been established. Application gets notified it by connect
6774 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6776 * Applied cras's patch to add silc_schedule_one function. The
6777 function runs scheduler once and returns.
6779 * Fixed the scheduler after cras messed it up. The timeout
6780 handling works now as it's supposed to work.
6782 * Added into lib/silccore/ silcnotify.h to include notify
6783 message types support. Changed silc_server_send_notify*
6784 functions, in server.[ch], to support those new notify types.
6785 Added the support for the notify types into client library,
6786 as well. Added new notify client operation into ops.h in
6789 * Changed silc_server_packet_send_to_channel to send normal
6790 packets instead of just channel message packets. The function
6791 is now used to send the notify packets to channels. It is not
6792 used to send channel message packets anymore, as server never
6795 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6796 va_arg()s as it seems to require it nowadays. I guess, if SILC
6797 is compiled with older va_arg() the new code should work anyway.
6799 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6801 * Splitted core library. Core library (lib/silccore) includes
6802 now only SILC protocol specific core (and common) components.
6803 Created new utility library (lib/silcutil) that includes more
6804 generic purpose stuff. The stuff for util library was taken
6805 from the old core library. This was minor and easy split.
6807 * Created SILC Client Library (lib/silcclient) that includes
6808 implementation of the SILC client without user interface. This
6809 was major move from silc/ directory. The code has been changed
6810 so that it is transparent towards the user interface. The
6811 silc/ directory includes now the same user interface as before
6812 and it uses the new client library. Read lib/silcclient/README.
6813 Basicly, the client library performs everything else related
6814 to SILC except user interface handling. Also, configuration
6815 files are considered to be part of user interface and library
6816 does not handle them.
6818 This change also changed a lot of structures, function naming etc.
6819 Most important change was that SilcClientWindow object was
6820 renamed to SilcClientConnection in the client library. Created
6821 also new file lib/silcclient/ops.h. Also added new files
6822 silc/local_command.[ch] and silc/client_ops.[ch].
6824 All these changes were made to make it easier for user interface
6825 designers to create what ever user interface for the SILC client
6828 It is also expected that the server will be moved to lib
6829 directory as well and SILC Server Library will be created;
6830 sometimes in the future.
6832 * Removed Local commands from lib/silccore/silccommand.h as
6833 they are application specific and new client library does not
6834 handle any of those anymore.
6836 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6837 old client implementation in silc/.
6839 * Added support for callback functions in SILC_LOG_* macros.
6840 Application can now set its own callbacks that will be called
6841 instead of using the default functions that will always print
6842 the debug messages to stderr (or stdout). Also, debugging can
6843 now be disabled by setting silc_debug to FALSE and re-enabled by
6844 setting it to TRUE. Note, that logging will still work even
6845 if debugging is disabled.
6847 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6848 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6849 silc_log_reset_debug_callbacks.
6851 * To enable debugging in silc client one must give now -d
6852 option on command line.
6854 * Changed silc_schedule_init to automatically allocate task queues
6855 if they are not allocated before calling it.
6857 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6859 * Added GMP 3.1 into math library.
6861 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6863 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6864 a channel in SILC network. The packet is used by servers and
6865 routers to notify other routers that user has left a channel.
6866 This little feature was missing until now. Added the feature
6867 to protocol specification as well.
6869 Added functions: silc_server_send_remove_channel_user and
6870 silc_server_remove_channel_user into server.[ch].
6872 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6873 lib/silccore/silcpacket.h. However, they are not implemented
6876 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6878 * Fixed joining to a channel and sending channel messages
6879 between server and router. The channel message sending should
6880 now work inside a cell.
6882 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6884 * Fixed the private message sending between server and router.
6885 The private message sending should now work inside a cell.
6887 * Added silc_server_replace_id into server.[ch] to replace
6888 existing ID in the SILC network.
6890 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6891 and silc_idlist_replace_server_id into idlist.[ch] in server.
6893 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6895 * Fixed the server to server connections. Server can again now
6896 connect to router. Router to router connections probably does
6899 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6901 * Added dynamic protocol registering support. Now protocols can
6902 registered and unregistered on the fly. Patch by cras.
6904 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6906 * Added lib/contrib directory to hold routines that some platforms
6907 don't have but are needed by SILC.
6909 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6910 into lin/contrib to provide getopt() and getopt_long() for
6911 those who don't have it.
6913 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6915 * Added AWAY command to client. When away message is set and
6916 client receives a private message packet the client automatically
6917 replies to the sender with the away message.
6919 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6920 bug seemed to be the cause of recent problems when compiling
6923 * Added version detection support to SKE protocol specification
6924 and added the new changes to the SKE implementation as well.
6925 There were other minor changes in the SKE protocol as well.
6927 Many changes in lib/silcske/silcske.[ch] and in
6928 lib/silcske/payload.[ch].
6930 * Added ^U functionality, clear input line. Patch from cras.
6932 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6934 * Mainly small bugfixes on core library. Fixed some debugging
6935 logging and buffer overflow in silclog.c.
6937 * Updated config.sub and config.guess on the distribution tree.
6939 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6941 * Added command lagging support in server. Client may execute
6942 commands now only once in two seconds.
6944 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6946 * Optimized packet reception. MAC computation and checking is now
6947 also more optimized. A lot previously duplicated code is now
6948 used as generic by both client and server.
6950 * Fixed key pair generation in clientutil.c
6952 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6954 * Added into lib/silccore/silcbufutil.[ch] new function;
6955 silc_buffer_realloc.
6957 * Moved generic packet sending/encryption functions to
6958 lib/silccore/silcpacket.[ch] from client and server. Some
6959 rewriting of the functions.
6961 * Moved all generic packet reception/decryption functions to
6962 lib/silccore/silcpacket.[ch] from client and server. The
6963 packet processing is now much cleaner in both client and server.
6964 These were major changes in both client and server.
6966 * Created many common functions in server to do packet sending.
6967 Previously code were duplicated a lot, this has been removed
6970 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6972 * Rewrote major parts of the ID cache system. Don't know
6973 whether it is better now or not but at least the API is more
6976 * Major rewrite on ID cache stuff on client because of the ID
6977 cache API changes. Added idlist.c to client.
6979 * Also major rewrite on ID cache stuff on server as well.
6980 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6981 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6982 in hand, instead they are all put into the ID cache system now.
6983 All server_idlist_* routines uses ID cache now instead of
6984 traversing its own lists (those lists does not exist anymore).
6985 SilcIDList though still exists. Also, SilcXXXEntry's are
6988 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6990 * Finally made the SKE implementation compliant to the protocol
6991 specification. All mp integers are now binary encoded as
6992 opposed being HEX encoded.
6994 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6997 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6998 functions: silc_[encode/decode]_pem. Also added function
6999 silc_encode_pem_file to PEM encode with newlines ('\n') for
7002 * SILC public keys are now encoded either PEM or binary. Same
7003 option is for private keys as well. By default private keys
7004 are binary encoded and public keys PEM encoded. Silly HEX
7005 encoding were removed.
7007 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7008 function to create fingerprints.
7010 * Fixed a bug in SHA1; does not change the original data anymore.
7012 * Partly implemented INFO command on client and server side.
7013 Fixed CLEAR command. Changes to SERVER command; show current
7014 server(s) when giving command without arguments. Added
7015 VERSION command to client.
7017 * Added check to server that unregistered connections cannot
7018 execute commands (unless it is specificly allowed).
7020 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7022 * Fixed screen refresh.
7024 * Fixed channel joining bug from client. On some circumstances
7025 client tried to join to a channel it had already joined.
7027 * Added public key verification process into client's protocol.c.
7028 The client now verifies the public key from user and saves
7029 it into ~./silc/serverkeys/ directory.
7031 Added into: clientutil.[ch]: silc_client_verify_server_key.
7033 * Changed SKE protocol's silc_ske_initiator_finish function
7034 to accept callback function that verifies the received public
7035 key. Removed old silc_ske_verify_public_key function.
7037 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7039 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7040 silc_pkcs_private_key[_data]_set.
7042 * Made the password and public authentication more cleaner in
7043 server's protocol.c.
7045 * Removed historic and obsolete protocol `channel_auth' from
7046 both client and server.
7048 * Removed wrong way of sending command status messages from
7049 server to client in server's command.c. The old way violated
7050 protocol specification.
7052 Changes to silccore/silccommand.[ch]: removed
7053 silc_command_encode_status_payload -> not needed anymore,
7054 changed silc_command_encode_payload_va to accept extra
7055 argument on variable argument list. The argument type must
7056 now be provided to the function. Also, added new function:
7057 silc_command_encode_reply_payload_va which is same as
7058 normal command_encode_payload_va except command status type
7059 is provided as extra argument.
7061 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7063 * Added ~./silc directory handling. The directory includes the
7064 public and private keys for the client.
7066 Added silc_client_check_silc_dir, silc_client_create_identifier
7067 and silc_client_load_keys.
7069 * Implemented SILC protocol compliant public key. Added public
7070 and private key saving to and loading from files.
7072 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7073 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7074 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7075 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7076 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7078 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7079 silc_pkcs_load_[public/private]_key.
7081 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7083 * Added silc_server_get_route (route.[ch]) to get connection
7084 data for the fastest route for given ID.
7086 * Implemented INVITE command on client and server. The command
7087 were re-defined in the SILC Protocol Specification and the
7088 implementation now complies with the specification.
7090 * Implemented PING command on client and server.
7092 * Implemented NAMES command on client and server. The server side
7093 supports currently only normal server not router server yet.
7094 Some changes to NAMES definition in SILC protocol specification.
7096 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7098 * Implemented LEAVE command on client and server.
7100 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7101 again. This change was made to the protocol as well. Server
7102 should not violate the protocol specification anymore.
7104 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7106 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7107 was tested. SOCKS4 was not but should work anyway.
