47 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
48 whether given configuration value has been given already.
50 Affected files silcd/serverconfig.[c], server.[c].
52 * Splitted the doc/example_silcd.conf.in. Separated the crypto
53 algorithm parts and created new file silcalgs.conf, that
54 is now included from the example_silcd.conf.in.
56 * Optimized the silc_server_connect_to_router_second to take
57 the connection configuration object from the SilcServerConnection
58 object instead of finding it during the connecting phase.
59 Added the configuration object to SilcServerConnection struct.
60 Affected files silcd/server_internal.h, server.c.
62 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

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

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

170 file lib/silcutil/silclog.c.
172 * Fixed the channel message payload decryption in the function
173 silc_channel_message_payload_decrypt to not modify the original
174 buffer before it is verified that the message decrypted
175 correctly. Otherwise, next time it is called with correct
176 channel key it won't encrypt since the payload is corrupted.
177 Affected file lib/silccore/silcchannel.c.
179 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

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

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

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

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

1002 Affected file irssi/src/silc/core/client_ops.c.
1004 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1006 * Fixed the silc_idcache_list_* routines to really support
1007 the dynamic list. Fixes a crash. Affected file is
1008 lib/silccore/silcidcache.c.
1010 * Fixed the LIST command reply to really call LIST command's
1011 pending callbacks. Affected file silcd/command_reply.c.
1013 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1015 * Update conn->local_entry->nickname after giving NICK
1016 command. Affected file lib/silcclient/command.c.

1026 * Save fingerprint in WHOIS command reply in server.
1027 Affected file silcd/command_reply.c.
1029 * Fixed NICK commands pending callback registration.
1030 Affected file lib/silcclient/command.c.
1032 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1034 * Use ++server->cmd_ident when sending commands in server,
1035 instead of random number. Affected file silcd/command.c.
1037 * Fixed GETKEY command reply to call actually GETKEY pending
1038 command callbacks. Affected file silcd/command_reply.c.
1040 * A bit stricter check for nicknames. Check for same nickname
1041 in NICK command also. Affected file silcd/command.c.
1043 * Do not call INFO command everytime client ID changes, only
1044 during first connecting. Affected file lib/silcclient/client.c.
1046 * Set the new nickname only after successful command reply for
1047 NICK command is returned by server. Affected file
1048 lib/silcclient/command.c.
1050 * Remove nicknames from nicklist during server_signoff notify.
1051 Should fix /NAMES bit more. The affected file is
1052 irssi/src/silc/core/silc-channels.c.
1054 * Added `fingerprint' field to the SilcIDListData in the
1055 silcd/idlist.h to hold the fingerprint of the client's
1058 Send the fingerprint of the client's public key in WHOIS
1061 Affected files silcd/command.c, and silcd/idlist.[ch].
1063 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1064 create fingerprint from given data.
1066 * Show the fingerprint of the client's public key in WHOIS.
1067 Affected files irssi/src/module-formats.[ch] and
1068 irssi/src/silc/core/client_ops.c.
1070 * Format the multiple same nicknames also during JOIN and
1071 NICK_CHANGE notifys. Affected file is
1072 lib/silcclient/client_notify.c.
1074 * Do not print error on screen for invalid private message
1075 payload since it can come if someone is sending private
1076 messages with wrong key. Affected file
1077 lib/silccore/silcprivate.c.
1079 * Fixed multiple concurrent /PING crash. Affected file
1080 lib/silcclient/command.c.
1082 * Changed the wrong ID encoding. All IP addresses must be
1083 in MSB first order in encoded format. They were encoded
1084 wrong and was in LSB format. Affected files are
1085 silcd/serverid.c, lib/silcutil/silcutil.c.
1087 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1089 * Call the `connect' client operation through the scheduler
1090 in case of error. Affected file lib/silcclient/client.c.
1092 * Call the `failure' client operation even if the error
1093 occurred locally during a protocol. Affected file is
1094 lib/silcclient/protocol.c.
1096 * Added support of sending LIST command to router from normal
1097 server. This way normal server can get list of all channels
1098 in the network too. Fixed the channel list sending in the
1099 server too. Affected files are silcd/command.c, and
1100 silcd/command_reply.[ch].
1102 * Added silc_server_update_channels_by_server and
1103 silc_server_remove_channels_by_server. They are used during
1104 disconnection of primary router and in backup router protocol.
1105 Affected file silcd/server_util.[ch], silcd/server.c and
1106 silcd/server_backup.c.
1108 * Fixed channel adding to global list in IDENTIFY command
1109 reply in server. Affected file silcd/command_reply.c.
1111 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1113 * If the incoming packet type is REKEY or REKEY_DONE process
1114 that packet always synchronously. Fixes yet another MAC
1115 failed error on slow (dialup) connections. Affected file
1116 lib/silcclient/client.c and silcd/server.c.
1118 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1120 * Call check_version SKE callback for initiator too. Affected
1121 file lib/silcske/silcske.c.
1123 * Implemented fix for security hole found in the SKE that was
1124 fixed in the specification few days back; the initiator's
1125 public key is now added to the HASH value computation.
1126 Added backwards support for the old way of doing it too, for
1127 old clients and old servers. Affected file is
1128 lib/silcske/silcske.c.
1130 * Enabled mutual authentication by default in SKE. If initiator
1131 is not providing mutual authentication the responder will
1132 force it. This will provide the proof of posession of the
1133 private key for responder. The affected files are
1134 lib/silcclient/protocol.c and silcd/protocol.c.
1136 * Do not cache anymore the server's public key during SKE.
1137 We do mutual authentication so the proof of posession of
1138 private key is done, and if the server is authenticated in
1139 conn auth protocol with public key we must have the public
1140 key already. Affected file silcd/protocol.c.
1142 * Added new global debug variable: silc_debug_hexdump. If
1143 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1144 file lib/silcutil/silclog.[ch].
1146 * Fixed compilation warning due to char * -> const char *.
1147 Affected files lib/silcutil/silcnet.h, and
1148 lib/silccore/silcauth.[ch].
1150 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1152 * Fixed CMODE command when new channel key was created. If
1153 the creation failed the old key was removed. Next time giving
1154 same command would crash the server since the old key was
1155 freed already. Affected file silcd/command.c.
1157 * Fixed the silc_server_announce_get_channels to not crash
1158 on reconnect. Affected file silcd/server.c.
1160 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1162 * Added silc_log_set_debug_string function to set a regex
1163 string to match for debug output. Only the function names,
1164 or filenames matching the given debug string is actually
1165 printed. This way it is possible to filter out those debug
1166 strings that user is not interested in.
1168 Fixed a bug in silc_string_regexify.
1170 Affected files lib/silcutil/silclog.[ch], and
1171 lib/silcutil/unix/silcunixutil.c.
1173 * Changed the -d options in both server and Irssi SILC client
1174 to take the debug string as argument. Affected files
1175 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1177 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1179 * Added silc_hash_babbleprint to create a Bubble Babble
1180 Encoded fingerprint. The encoding is developed by Antti
1181 Huima (draft-huima-babble-01.txt), and it creates human
1182 readable strings out of binary data. Affected file
1183 lib/silccrypt/silchash.[ch].
1185 * Print the babble print now in addition of fingerprint as well
1186 in Irssi SILC client. Affected files are
1187 irssi/src/fe-common/silc/module-formats.[ch],
1188 irssi/src/fe-common/silc/core/client_ops.c.
1190 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1192 * Fixed a security problem found in SKE. The initiator's
1193 public key too is now added to the HASH hash value creation
1194 which is signed by the responder to create the SIGN value.
1195 This will prevent anyone in the middle to lie to the responder
1196 about the initiator's public key. If this is done now, the
1197 man in the middle will get caught. Updated the protocol
1200 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1202 * Better installation directory handling. Configure module
1203 paths and other paths automatically to example_silc* files
1204 in doc/. A patch by toma.
1206 * Fixed compiler warning from MPI library, and from SILC RNG.
1209 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1210 It can be configured with ./configure. A patch by toma.
1212 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1214 * Find correct make to use in prepare-clean. A patch by
1215 toma. Affected file prepare-clean.
1217 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1219 * Added irssi variables use_auto_addr, auto_bind_ip,
1220 auto_bind_port and auto_public_ip.
1222 * Changed the interface for silc_client_send_key_agreement
1223 in lib/silcclient/silcapi.h
1227 irssi/src/silc/core/silc-core.c
1229 lib/silcclient/silcapi.h
1230 irssi/src/silc/core/silc-channels.c
1231 lib/silcclient/client_keyagr.c
1234 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1236 * Added silc_pkcs_public_key_compare to compare two
1237 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1239 * Check that the client who set the founder mode on the
1240 channel is the same client that is giving the founder
1241 mode to itself. It is done by comparing the saved public
1242 key (it is saved even in the authentication is passphrase).
1243 Affected file silcd/command.c.
1245 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1247 * Do not process packet for disconnected socket connection.
1248 Affected file lib/silccore/silcpacket.c.
1250 * Process the DISCONNECT packet through scheduler in the
1251 client library. Affected file lib/silcclient/client.c.
1253 * Fixed the silc_client_packet_parse to not to increase
1254 the packet sequence number if the conn->sock and the
1255 current socket connection is not same. This can happen
1256 for example during key agreement when the conn includes
1257 multiple socket connections (listeners). Affected file
1258 lib/silcclient/client.c.
1260 * The sender of the file transfer request now provides also
1261 the pointer (listener) for the key exchange protocol. If
1262 the listener cannot be created then it sends empty key
1263 agreement and lets the receiver provide the listener.
1265 Added `local_ip' and `local_port' arguments to the
1266 silc_client_file_send. If they are provided they are used,
1267 if not then it will attempt to find local IP address, if
1268 not found or bind fails then the remote client will provide
1271 Affected files are lib/silcclient/client_ftp.c and
1272 lib/silcclient/silcapi.h.
1274 * Extended the FILE SEND command to support defining the
1275 local IP and port for key exchange listener. They are
1276 optional. Affected file irssi/src/silc/core/silc-servers.c.
1278 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1280 * Defined to WHOIS command reply the sending of fingerprint
1281 of the client's public key (if the proof of posession of the
1282 corresponding private key is verified by the server).
1283 Updated to the protocol specification.
1285 * Added support of receiving the client's public key's
1286 fingerprint in command reply in client library. Affected
1287 file is lib/silcclient/command_reply.c, and
1288 lib/silcclient/idlist.[ch].
1290 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1292 * Do not send over 128 chars long nickname to the server
1293 in NICK command. Affected file lib/silcclient/command.c.
1295 * Do not send over 256 chars long channel names to the server
1296 in JOIN command. Affected file lib/silcclient/command.c.
1298 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1300 * Assure that silc_server_close_connection cannot be called
1301 twice for same socket context. Affected file is
1304 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1306 * Send error message to application if opening file for
1307 writing during file transfer fails. Affected file is
1308 lib/silcclient/client_ftp.c.
1310 Remove all file transfer sessions for a client that we're
1311 removing from ID cache.
1313 Affected file is lib/silcclient/client_ftp.c.
1315 * Fixed silc_net_addr2bin to return correct address. Affected
1316 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1318 * Fixed file transfer session removing on signoff notify.
1319 Affected file irssi/src/silc/core/silc-servers.c.
1321 * Added the SilcClientFileError to be returned in the monitor
1322 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1323 Affected file lib/silcclient/silcapi.h.
1325 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1327 * Fixed a crash in silc_client_ftp_free_sessions and
1328 silc_client_ftp_session_free_client. Affected file
1329 lib/silcclient/client_ftp.c.
1331 * Added `disabled' field in the SilcChannelEntry in the server
1332 to indicate if the server entry is disabled. Affected file
1333 silcd/idlist.h, silcd/command[_reply].c.
1335 * SILC server adds now /var/run/silcd.pid everytime it is
1336 started. Affected file silcd/silcd.c.
1338 * Added silc_server_packet_send_clients to send a packet to
1339 the provided table of client entries. Affected file
1340 silcd/packet_send.[ch].
1342 * Fixed a crash in client resolving in client_prvmsg.c in
1343 client library. Affected file lib/silcclient/client_prvmsg.c.
1345 * Do not actually remove the client directly from ID cache
1346 during SERVER_SIGNOFF, but invalidate it. This way we
1347 preserve the WHOWAS info for the client. Affected file
1348 silcd/server_util.c.
1350 * Fixed SERVER_SIGNOFF notify handling in the server. The
1351 server is now able to process incoming SERVER_SIGNOFF notify
1352 for a server that it doesn't even know about. It will remove
1353 the clients provided in the notify. Affected file
1354 silcd/packet_receive.c.
1356 * Check for partial packet in data queue after every packet that
1357 was found from the queue. Return and wait for more data if
1358 there is partial data in queue. Affected file is
1359 lib/silccore/silcpacket.c.
1361 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1363 * Added SilcClietFileError enum to indicate error in
1364 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1365 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1366 Affected files lib/silcclient/silcapi.h and
1367 lib/silcclient/client_ftp.c.
1369 * Check that newsize in silc_buffer_realloc is larger than
1370 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1372 * Added better monitor of file transfers. It now monitors
1373 key agreement protocol during the file transfer too. Added
1374 error reporting too. Affected files
1375 irssi/src/silc/core/silc-servers.c,
1376 irssi/src/fe-common/silc/module-formats.[ch].
1378 * Wrote a help file for FILE command.
1380 * Added silc_rng_global_get_byte_fast to get not-so-secure
1381 random data as fast as possible. Random data is read from
1382 /dev/urandom if available and from the SILC RNG if not
1383 available. It is used in padding generation. Affected file
1384 lib/silccrypt/silcrng.[ch].
1386 * All packets in client library are now processed synchronously.
1387 Optimized packet processing a lot. Affected file
1388 lib/silcclient/client.c.
1390 * All server connection packets are processing synchronously
1391 now in server, to optimize packet processing. Affected file
1394 * Include files are installed now only in Toolkit distribution
1395 if make install is given. Affected files: all Makefile.am's.
1397 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1399 * Assure that silc_client_notify_by_server_resolve does not
1400 resolve the client information multiple times. If it cannot
1401 be found by the first it cannot be found at all. Affected
1402 file lib/silcclient/client_notify.c.
1404 * Fixed WHOWAS command reply calling. Affected file
1405 lib/silcclient/command_reply.c.
1407 * Removed all references to silc_idlist_get_client from the
1408 Irssi SILC client since that call is internal call used by
1409 the library. The Irssi SILC client will use now client
1410 retrieval functions found in silcapi.h.
1412 * Fixed a bug in resolving nickname info before sending
1413 private message. It used freed memory. Affected file
1414 irssi/src/silc/core/silc-servers.c.
1416 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1418 * Assure my_channels statistics cannot go negative in server.
1419 Affected files silcd/server.c, silcd/server_util.c.
1421 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1423 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1425 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1427 * Win32 Toolkit changes. Affected files
1428 win32/silc.dsw, win32/libsilc/libsilc.def,
1429 win32/libsilcclient/libsilc.def,
1430 lib/silcutil/silcutil.c, and
1431 lib/sftp/sftp_fs_memory.c.
1433 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1435 * Added silc_net_localip to return local host's IP address.
1436 Affected file lib/silcutil/silcnet.[ch].
1438 * If key exchange or rekey protocol is active for a connection
1439 parse all packets syncronously since there might be packets
1440 in packet queue that we are not able to process without first
1441 processing packets before them. Affected file silcd/server,
1442 lib/silcclient/client.c.
1444 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1445 whether library should continue processing the packet.
1446 Affected file lib/silccore/silcpacket.h.
1448 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1449 SilcSFTPMonitorData to SFTP server to monitor various
1450 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1451 lib/silcsftp/sftp_server.c.
1453 * Added silc_file_size to return file size. Affected file
1454 lib/silcutil/silcutil.[ch].
1456 * Implemented the file transfer support for the client library.
1457 Added preliminary support for simple client to client one-file
1458 transmission. Affected file lib/silcclient/client_ftp.c,
1459 lib/silccilent/client.[ch].
1461 * Added new local command FILE to the Irssi SILC Client.
1462 It is used to perform the file transfer. It has subcommands
1463 SEND, RECEIVE, SHOW and CLOSE. Affected files
1464 irssi/src/silc/core/client_ops.c,
1465 irssi/src/silc/core/silc-server.[ch].
1467 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1469 * Relay the SILC_PACKET_FTP in the server. Affected files
1470 silcd/server.c and silcd/packet_receive.c.
1472 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1474 * Renamed silc_file_read and silc_file_write to functions
1475 silc_file_readfile and silc_file_writefile. Added function
1476 silc_file_open and silc_file_close. Affected files
1477 lib/silcutil/silcutil.[ch].
1479 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1481 * Resolve the client info when received private message or
1482 channel message for a client which nickname we don't know.
1483 Affected files lib/silcclient/client_prvmsg.c and
1484 lib/silcclient/client_channel.c.
1486 * Do not crash in /KEY if client is not connected. Affected
1487 file irssi/src/silc/core/silc-channels.c.
1489 * Added SilcClientStatus field to the SilcClientEntry in the
1490 lib/silcclient/idlist.h.
1492 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1493 is incomplete and is being resolved, it won't be resolved
1496 Make sure also that USERS command reply does not resolve
1497 twice information. Affected file is
1498 lib/silcclient/command_reply.c.
1500 Make sure that silc_client_get_clients_by_list does not
1501 resolve twice same information.
1503 * Check for valid client->id in the silc_server_free_client_data.
1504 Affected file silcd/server.c.
1506 * Fixed /GETKEY nick@server not to crash if the server entry
1507 is not found. Affected file lib/silcclient/command.c.
1509 * Fixed the silc_server_check_cmode_rights to check the
1510 requested modes correctly. Affected file silcd/command.c.
1512 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1514 * Better checks for non-printable chars in nick added.
1515 Affected file silcd/command.c.
1517 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1519 * Call the silc_server_udpate_servers_by_server in the
1520 primary router that comes back online in the backup resuming
1521 protocol. Otherwise it routes packets wrong. Affected file
1522 silcd/server_util.[ch], silcd/server_backup.c.
1524 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1526 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1527 lib/silcutil/silcbuffmt.[ch].
1529 * Redefined the SILC packet header to include the padding
1530 length. Affected file lib/silccore/silcpacket.[ch].
1532 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1533 length for maximum padding up to 128 bytes). Affected
1534 file lib/silccore/silcpacket.h.
1536 * Removed all backwards support for old 0.5.x MAC thingies.
1537 The SILC packet header change makes it impossible to be
1538 backwards compatible.
1540 * Send the ENDING packet with timeout in the backup resuming
1541 protocol. This is to assure that all routers has connected
1542 to the primary router. Affected file silcd/server_backup.c.
1544 * Changed the RNG to take the first IV from random data. It
1545 used to take it from zero actually. Changed the RNG also
1546 to use /dev/urandom during session. /dev/random is used
1547 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1549 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1551 * Changed the SILC packet header to have the first two bytes
1552 (the packet length) encrypted. Affected files aroung the
1553 code tree, lib/silccore/silcpacket.[ch]. Removed the
1554 SilcPacketCheckDecrypt callback. It is not needed anymore
1555 since the silc_packet_receive_process will determine now
1556 whether the packet is normal or special.
1558 * Implemented the unidirectional MAC keys. Affected files
1559 lib/silcske/silcske.c, silcd/protocol.c and
1560 lib/silcclient/protocol.c.
1562 * Implemented the packet sequence number to the MAC computation.
1563 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1564 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1565 lib/silcclient/protocol.c.
1567 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1569 * Allow backup router to announce servers. All servers
1570 announced by backup router are added to the global list
1571 automatically. Update hte server's socket to our primary
1572 router also when backup router announces a server.
1573 Affected file silcd/packet_receive.c.
1575 * Do not update the client->router in the function
1576 silc_server_udpate_clients_by_server if the client is on
1577 global list. We might fail to find any specific server
1578 for locally connected clients and local cell clients. They
1579 should still use the `from' and not `to' as client->router.
1580 This fixes backup router resuming protocol. Affected file
1581 silcd/server_util.c.
1583 * Decrease channel statistics count only if the channel
1584 deletion worked. Affected files are silcd/server.c and
1585 silcd/server_util.c.
1587 * Added silc_server_update_servers_by_server to update origin
1588 of all server entries. Used during backup router protocol.
1589 Affected files silcd/server_util.[ch], silcd/server.c. and
1590 silcd/backup_router.c.
1592 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1593 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1594 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1595 lib/silccrypt/silchmac.c.
1597 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1599 * Assure that router cannot reroute the same channel message
1600 to the sender. Affected file silcd/packet_receive.c.
1602 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1604 * Made better checks that the channel message is not sent
1605 to the router it came from. Affected file is
1606 silcd/packet_send.c. Fixed memory leak too.
1608 * Announce informations for incoming router connection, but
1609 only after checking if it is replaced by backup router.
1610 Affected file silcd/packet_receive.c.
1612 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1614 * Fixed the backup resuming protocol to work in multiple
1615 router environment. Affected file silcd/server_backup.c.
1617 * Route packet only to one router in the function
1618 silc_server_packet_send_to_channel. Affected file is
1619 silcd/packet_send.c.
1621 * Fixed silc_server_send_notify_dest to set the broadcast
1622 flag. Fixed the silc_server_send_notify_topic to actually
1623 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1624 Affected file silcd/packet_send.c.
1626 * Changed the SFTP Filesystem interface. Changed the
1627 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1628 the filesystem operation function. The SilcSFTPFilesystem
1629 is now a context that is allocated by all filesystem allocation
1630 functions and it already includes the operations structure
1631 and filesystem specific context. It is given as argument
1632 now to the silc_sftp_server_start. This made the interface
1633 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1634 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1636 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1638 * Changed the backup router adding and getting interfaces
1639 in the server. The router that will be replaced by the
1640 specified backup router is now sent as argument. Affected
1641 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1644 * Added silc_net_addr2bin_ne to return the binary form of
1645 the IP address in network byte order. Affected files
1646 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1648 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1650 * Check for existing server ID in silc_server_new_server
1651 and in silc_server_connect_to_router_final and remove the
1652 old entry if it exists. Affected file silcd/packet_receive.c,
1655 * Send the channel message always to only one router, either
1656 in upstream or downstream. Affected file is
1657 silcd/packet_send.c.
1659 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1661 * Wrote the definition of the backup resuming protocol to the
1662 protocol specification.
1664 * Removed one redundant channel key generation from normal
1665 server during joining procedure. Removed one redundant
1666 channel key sending from server to router during joining
1667 procedure. Affected file silcd/command.c.
1669 * Made minor bugfixes to the backup router resuming protocol.
1670 Affected file silcd/server_backup.c, server.c.
1672 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1674 * Added --disable-asm configuration option. Affected files
1675 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1678 * Implemented the backup resuming protocol that is used to
1679 resume the primary router position in the cell after the
1680 primary router comes back online. Affected files
1681 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1682 and silcd/server_util.[ch].
1684 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1686 * Sleep two (2) seconds after sending QUIT command to server.
1687 Affected file lib/silcclient/command.c.
1689 * Assure that if outgoing data buffer is pending do not force
1690 send any data. Affected file silcd/packet_send.c.
1692 * Assure that if outgoing data buffer is pending do not force
1693 send any data. Affected file lib/silcclient/client.c.
1695 * Implemented the backup router support when the primary router
1696 goes down. The servers and routers can now use the backup
1697 router as new primary router without loosing connectivity.
1699 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1701 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1702 in the server to indicate disabled entry. All data read
1703 from the connection will be ignored and no data is sent
1704 for entry that is disabled. Affected files are
1705 silcd/idlist.h, silcd/server.c.
1707 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1709 * Created SFTP client and server test programs in the
1710 lib/silcsftp/tests directory.
1712 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1714 * Implemented memory filesystem (virtual filesystem) for
1715 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1718 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1720 * Implemented the SFTP (SSH File Transfer Protocol) to the
1721 lib/silcsftp. It includes SFTP client and SFTP server
1724 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1726 * Moved lib/silccore/silcprotocol.[ch] to the
1727 lib/silcutil library.
1729 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1730 take variable argument list pointer as argument. Affected
1731 file lib/silcutil/silcbuffmt.[ch].
1733 * Added silc_buffer_set function that is used to set data
1734 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1735 Affected file lib/silcutil/silcbuffer.h.
1737 * Changed various routines in the core library to use the new
1738 silc_buffer_set instead of allocating new buffer only for
1741 * Added 64-bit value formatting and unformatting support to the
1742 silc_buffer_[un]format routines. Affected file is
1743 lib/silcutil/silcbuffmt.[ch].
1745 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1746 to includes/bitmove.h.
1748 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1750 * Fixed channel user mode saving in client library. Affected
1751 file lib/silcclient/command[_reply].c.
1753 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1755 * Defined the file transfer to the SILC Protocol. Added
1756 new packet type SILC_PACKET_FTP and defined File Transfer
1757 Payload. The mandatory file transfer protocol is SFTP
1758 (SSH File Transfer Protocol). Affected file in addition
1759 of the internet draft is lib/silccore/silcpacket.h.
1761 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1762 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1763 is used as part of backup router protocol when the primary
1764 router of the cell is back online and wishes to resume
1765 the position as primary router.
1767 * Redefined the MAC generation keys in the protocol. The
1768 same key is not used anymore in both direction. Both
1769 direction will now use different keys for sending and
1770 receiving. This fixes a potential security flaw. This
1771 change causes incompatibilities in the protocol.
1773 * Redefined also the MAC computation from the packet.
1774 An packet sequence number is now added to the MAC
1775 computation. This prevents possible replay attacks against
1776 the protocol. This change too causes incompatibilities
1779 Added `sequence' field to the SilcPacketContext to hold
1780 the current sequence number for the packet.
1782 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1784 * Added `created' field to the SilcIDListData in the file
1785 silcd/idlist.h to indicate the time when the entry was
1788 * Added `created' field to the SilcChannelEntry too. Affected
1789 file silcd/idlist.h.
1791 * Added `creation_time' aguments to all the announcement functions
1792 in the server. If it is provided then only the entries that
1793 was created after the provided time frame are actually
1794 announced. Affected file silcd/server.[ch].
1796 * The protocol says that the Channel ID's IP address must be
1797 based on the router's IP address. Added check for this in
1798 the silc_server_new_channel when processing incoming New Channel
1799 Payload. Affected file silcd/packet_receive.c.
1801 * Print out the correct version with --version in SILC client.
1802 Affected file irssi/src/silc/core/silc-core.c.
1804 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1806 * Fixed WHOWAS command to check for completnes of the client
1807 entry always, not just when the command is coming from client.
1808 Affected file silcd/command.c.
1810 * Added new function silc_server_packet_queue_purge to purge the
1811 outgoing data queue to the network. After the function returns
1812 it is guaranteed that the outgoing packet queue is empty.
1813 Affected file silcd/packet_send.[ch].
1815 * Purge the outgoing packet queue in the rekey protocol's final
1816 callback to assure that all rekey packets go to the network
1817 before quitting the protocol. Affected file silcd/server.c.
1819 * Added silc_client_packet_queue_parse as similar function as
1820 in server to the client library. The affected file is
1821 lib/silcclient/client.c.
1823 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1825 * Splitted silcd/server.c and created silcd/server_util.[ch]
1826 for utility functions.
1828 * Added new socket flag SILC_SF_DISABLED to indicate that the
1829 connection is open but nothing can be sent to or received from
1830 the connection. Affected file lib/silcutil/silsockconn.[ch].
1831 The checking for disabled socket is checked in the low level
1832 silc_socket_write and silc_socket_read functions.
1834 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1836 * Allow only nicknames and channel names that fits into the
1837 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1839 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1841 * When processing JOIN command reply in server check that if
1842 the channel exists in our global list we'll move it the local
1843 list. Affected file silcd/command_reply.c.
1845 * Fixed the check whether client is joined on the channel already
1846 in JOIN command. Affected file lib/silcclient/command.c.
1848 * Fixed the JOIN command reply to check whether the channel
1849 already exists. Affected file lib/silcclient/command_reply.c.
1851 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1853 * Added silc_ske_status_string to map the SKE error numbers
1854 to readable strings. The affected files are
1855 lib/silcske/silcske[_status].[ch].
1857 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1859 * Do not show the private channels on the WHOIS channel list
1860 as it is not allowed by the protocol. The affected file is
1863 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1865 * Assure that the packet length digged from the actual packet
1866 is something sensible in the silc_packet_decrypt_rest_special
1867 in lib/silccrypt/silcpacket.c.
1869 * Free and NULL the allocated pointer in silc_hmac_alloc if
1870 the HMAC allocation fails. The affected file is
1871 lib/silccrypt/silchmac.c.
1873 * Print the selected security properties to the log files in
1874 the server. Affected file silcd/protocol.c.
1876 * Add SKE's reference counter even if calling the completion
1877 callback manually. Otherwise it goes negative, although it
1878 does not cause any problems. The affected file is
1879 lib/silcske/silcske.c.
1881 * Remove the client entry with short timeout after giving the
1882 KILL command. Affected file lib/silcclient/command.c.
1884 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1885 case all found clients are already disconnected (WHOWAS would
1886 found them) in the server. Affected file silcd/command.c.
1888 * Update the last_receive (time of last data received) to be
1889 updated only when received private or channel message so that
1890 the idle time showed in WHOIS makes more sense.
1892 * Added boolean field `valid' in to the SilcClientEntry in the
1893 client library to indicate whether the entry is valid or not.
1894 This fixes the nickname change bug on channel when changing
1895 the nickname to be same than the old (like nick to Nick) the
1896 nickname formatter doesn't set the new nick anymore to Nick@host.
1897 Affected file lib/silcclient/idlist.[ch].
1899 * Now actually fixed the nickname changing on disconnection.
1900 Added new function silc_change_nick to the Irssi SILC Client.
1901 Affected file irssi/src/silc/core/client_ops.c,
1902 irssi/src/silc/core/silc-nicklist.[ch].
1904 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1906 * Check that the public key exists in the GETKEY command before
1907 trying to encode it. Affected file silcd/command.c.
1909 * Print some notifications on received public keys with GETKEY
1910 command in the Irssi SILC Client. Affected files are
1911 irssi/src/fe-common/silc/module-formats.[ch],
1912 irssi/src/silc/core/client_ops.c.
1914 * Use IDENTIFY command to resolve the server information in the
1915 GETKEY command instead of INFO command. Affected file
1916 lib/silcclient/command.c.
1918 * All command reply functions in the client library now calls
1919 the pending command reply callbacks even if an error has
1920 occurred. The server has done this a long time and now it was
1921 time to move the client library to this as well. Now all
1922 errors can be delivered back to the pending command reply
1923 callbacks if necessary. Affected files are
1924 lib/silcclient/command[_reply].[ch].
1926 * Change the nickname on disconnection back to the username
1927 because in reconnect the server will enforce it to it anyway.
1928 Affected file irssi/src/silc/core/silc-servers.c.
1930 * Fixed a config file parsing bug in the Irssi SILC client.
1931 Affected file irssi/src/silc/core/clientconfig.c.
1933 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1935 * When printing the channel mode on JOIN, verify that the
1936 channel key and channel's HMAC are valid. Affected file
1937 irssi/src/silc/core/client_ops.c.
1939 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1941 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1942 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1943 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1945 * Removed channel key rekey task deleting from the function
1946 silc_server_save_channel_key. Affected file silcd/server.c.
1947 Added explicit timeout task context instead that is used to
1948 delete the task if we are registering a new task before the
1949 new task has elapsed.
1951 * When channel key rekey occurs the client library now saves
1952 the old channel key for a short period of time (10 seconds) and
1953 is able to use it in case some is still sending channel
1954 messages encrypted with the old key after the rekey. Affected
1955 file lib/silcclient/[idlist.h|client_channel.c].
1957 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1959 * Added check to the silc_server_new_id_real to not accept
1960 new ID if it is the sender's own ID. Affected file is
1961 silcd/packet_receive.c.
1963 * Assure that we do not announce ourself or the one we've
1964 sending our announcements when we're router and are announcing
1965 servers to our primary router. Affected file silcd/server.c.
1967 * Fixed silc_server_command_identify_check_client to assemble
1968 correct WHOIS packet. It send corrupted WHOIS packet and
1969 caused problem with router to router connections. Affected
1970 file silcd/command.c.
1972 Fixed also silc_server_command_whois_check the same way
1973 as for the IDENTIFY command.
1975 * Added new SilcIDListStatus to the server in the SilcIDListData
1976 structure. The status now includes the current status of
1977 the entry (like registered, resolved etc.). Affected file
1978 silcd/idlist.[ch]. Defined a bunch of different status types
1979 as well. This replaced the old boolean registered field as well.
1981 Added resolve_cmd_ident field to the SilcClientEntry structure
1982 too so that if the entry is for example being resolved so
1983 another command may attach to the same pending command reply
1984 without requiring to resolve the same entry again. This concept
1985 should optimize the WHOIS and the IDENTIFY resolving under
1986 heavy load by taking away unnecessary resolving for entries
1987 that are being resolved already.
1989 Added support for adding multiple pending commands for one
1990 command idenfier. Affected file silcd/command[_reply].[ch].
1992 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1993 before deleting the data. Otherwise the hash table will have
1994 freed data in comparison functions. Affected file is
1995 silcd/command_reply.c.
1997 * Fixed silc_idlist_replace_client_id to add the new entry to
1998 the cache with NULL nickname. Otherwise there will be invalid
1999 memory as the nickname after the nickname is freed. Affected
2000 file silcd/packet_receive.c.
2002 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2003 saved into wrong slots because the previous number of entries
2004 was not taken into account. Affected file silcd/idlist.c.
2005 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2007 * If we are router and we receive JOIN notify to a channel that
2008 does not have any users then notified client is marked as the
2009 channel founder, as it is it. The affected file is
2010 silcd/packet_receive.c
2012 * Added to the extended hash table API's table_del_*ext functions
2013 the destructor as argument too, so that the caller can decide
2014 which destructor to use or whether to use destructor at all.
2015 Affected file lib/silcutil/silchashtable.[ch].
2017 * Fixed ID Cache purging. It actually deleted the entries from
2018 the hash table after the data was freed. The hash table ended
2019 up comparing freed memory. The affected file is
2020 lib/silccore/silcidcache.c.
2022 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2024 * Fixed Irssi SILC client's KILL command's HELP syntax.
2026 * The USERS command now resolves the detailed user information
2027 if the userinfo field is missing. Affected file is
2028 lib/silcclient/command_reply.c.
2030 * Do not print error in silc_file_read if the read file does
2031 not exist. Just silently return NULL. Affected file is
2032 lib/silcutil/silcutil.c.
2034 * Fixed the silc_log_output to not wine about NULL filename
2035 and to not create some bogus " " filename. Affected file is
2036 lib/silcutil/silclog.c.
2038 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Fixed various printing bugs on the user interface in the
2041 Irssi SILC Client. Minor changes that were forgotten from
2044 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2046 * Fixed the configure.in.pre and the compilation and distribution
2047 environment to support the new autoconf 2.52. That version is
2048 now required to compile the CVS trunk.
2050 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2052 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2053 to generally parse user@fqdn format strings. Affected file
2054 lib/silcutil/silcutil.c.
2056 * Added nickname_format and nickname_force_format fields to the
2057 SilcClientParams structure. The first one defines the format
2058 for the nicknames that the library will enforce if the receives
2059 multiple same nicknames. The second one is boolean value and
2060 can be used to force the library to always enforce the format
2061 to the nicknames regardles whether there are multiple nicknames
2062 or not. This configurable formatting was employed to flexibly
2063 support accessing multiple nicknames from the user interface.
2064 The userinterface can now set the nicknames to what ever format
2065 they prefer. Affected file lib/silcclient/silcapi.h.
2067 Added function silc_client_nickname_format to the file
2068 lib/silcclient/idlist.c. It performs the nickname formatting.
2070 Added new field `hostname´ to the SilcClientEntry context.
2071 It holds the hostname of the client. Affected file is
2072 lib/silcclient/idlist.h.
2074 * Irssi SILC Client sets the nicknames in nick@hostn format.
2075 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2076 irssi/src/silc/core/silc-core.c.
2078 The WHOIS printing now also shows both the real nickname and
2079 the formatted nickname so that user knows how to access the
2080 user if there are multiple same nicknames cached. Affected
2081 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2082 printing formatting too to take the hostname now as a separate
2083 argument. The Affected file is
2084 irssi/src/fe-common/silc/modules-formats.[ch].
2086 * Changed the silc_client_get_clients_local to accept the formatted
2087 nickname as argument. It accepts the real nickname too but the
2088 formatted nickname can be used to find the true entry from
2089 multiple entries. Affected file lib/silcclient/silcapi.h and
2090 lib/silcclient/idlist.c.
2092 * Added nickname_format_parse field to the SilcClientParams.
2093 It is a callback function provided by the application to parse
2094 the nickname out of the formatted nickname string. The library
2095 calls it to get the nickname from the formatted string. Since
2096 the application generally knows better the format of the nickname
2097 string it parses it instead of the library, even though library
2098 encodes the formatted string. If the callback function is not
2099 provided then the library will use the string as is. The
2100 affected file is lib/silcclient/silcapi.h.
2102 * All the nickname strings passed to the client library in
2103 commands are now expected to be formatted nickname strings.
2104 If the command does not support the formatted nickname string
2105 it will assume that the sent string is the actual nickname.
2106 Affected file lib/silcclient/command.c.
2108 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2110 * Added public key authentication support to OPER and SILCOPER
2111 commands in the client library. Affected file is
2112 lib/silcclient/command.c.
2114 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2116 * Changed the get_auth_methdod client operation to be asynchronous.
2117 It can be async if the application resolves the authentication
2118 method from the server during the negotiation. Added new
2119 SilcGetAuthMeth completion callback that the application will
2120 call after resolving the authentication method.
2122 Added function silc_client_request_authentication_method that
2123 the application can use to resolve the authentication method
2124 from the server. Added also SilcConnectionAuthRequest callback
2125 that the library will call after the server has replied. The
2126 application can call this function if it does not know the
2127 current authentication method.
2129 Affected files are lib/silcclient/client.c and
2130 lib/silcclient/silcapi.h.
2132 * The Irssi SILC client now automatically resolves the authentication
2133 method incase any configuration information is not present (and
2134 currently there never is). The affected file is
2135 irssi/src/silc/core/client_ops.c.
2137 * Fixed public key authentication from the client library.
2138 Affected file lib/silcclient/protocol.c. Changed also the
2139 protocol specification about the public key authentication in
2140 the connection authentication protocol. The actual data to be
2141 signed is now computed with a hash function before signing.
2143 * Fixed the public key authentication from the server as well.
2144 Affected file silcd/protocol.c.
2146 * Removed the mlock()'s from the memory allocation routines.
2147 Affected file lib/silcutil/silcmemory.c. The ./configure does
2148 not check anymore for the mlock(). Affected file is
2151 * Fixed USERS command in server to allow the execution of the
2152 command for private and secret channels if the client sending
2153 the command is on the channel. Affected file silcd/command.c.
2155 * Fixed silc_client_get_clients_local to return the clients
2156 count correctly. It could return wrong value. Affected file
2157 lib/silcclient/idlist.c.
2159 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2161 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2162 types. The assembler optimizations seemed not to like 64-bit
2163 data types. The assmebler optimizations thus are now enabled
2164 also for BSD systems as opposed to only enable them for Linux.
2166 * Do not check for threads at all on BSD systems. Affected
2167 file configure.in.pre.
2169 * Removed -n and -h options from the Irssi SILC Client since
2170 they are not used in silc.
2172 * Fixed the prime generation to assure that the first digit
2173 of the generated random number is not zero since our conversion
2174 routines does not like number strings that starts with zero
2175 digit. If zero digit is seen the random number is regenerated.
2176 This caused some corrupted RSA keys when the zero first digit
2177 was met. Affected file lib/silcmath/silcprimegen.c.
2179 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2181 * Fixed WIN32 configuration in the ./configure script.
2182 Fixed to include xti.h on environments that has it.
2183 Patches by Carsten Ilchmann and andrew.
2185 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2187 * Changed the silc_id_create_client_id to be collision
2188 resistant. It is now assured that there cannot be created
2189 two same client ID's. I suspect that some weird bugs in
2190 the server were actually caused by duplicate Client IDs.
2191 Affected file silcd/serverid.[ch]. A router receiving
2192 new ID now also assures and informs the sending server
2193 if the ID caused collision.
2195 * Changed the silc_id_create_channel_id to also assure that
2196 there are no collisions.
2198 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2200 * Statement about ignoring the Mutual Authentication flag when
2201 performing rekey with PFS was a bit misleading. It is ignored
2202 if it was set in the initial negotiation, it cannot be even
2203 set in the rekey. Fixed in the ke-auth draft. Started the
2204 new versions of the protocol drafts in the doc/.
2206 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2208 * Fixed a bug in silc_client_command_identify_save when saving
2209 new channel information. The channel name was no duplicated
2210 and caused crash on exit. Affected file is
2211 lib/silcclient/command_reply.c.
2213 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2215 * Fixed the getkey command handling in the server. Send just
2216 empty OK reply to the sender if the key could not be fetched
2217 (but everything else was ok, like the key just was not available).
2218 Changed the public key parameter to optional in the protocol
2219 specs so that empty OK reply can be sent. Affected file
2222 Added a message to Irssi SILC client to tell to user if the
2223 server did not return a public key.
2225 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2227 * Fixed a channel key regeneration bug. It registered new
2228 timeout tasks exponentially until all system resources were
2229 used. Affected file silcd/server.c.
2231 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2233 * Added the SILC Document generator to the scripts/silcdoc.
2234 It can be used to generate the Toolkit Reference Manual out
2235 of the source tree. Internally it will also use the RoboDoc
2236 generator now imported in util/robodoc.
2238 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2240 * Added couple of return's in rekey protocol if error orccurred
2241 during the protocol. The execution must be terminated.
2242 Affected file silcd/protocol.c. Also, terminate the protocol
2243 always with timeout.
2245 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2247 * The client's Client ID was created initally from the wrong
2248 nickname (it could have been in format nick@host) in the
2249 silc_server_new_client. Affected file silcd/packet_receive.c
2251 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2253 * Added some SILC_LOG_ERROR's to various error conditions
2254 if client could not be added to ID cache. Affected files
2255 silcd/packet_receive.c and silcd/server.c.
2257 * When client's sock->user_data is freed, NULL also the
2258 client->router and client->connection pointers. Added check
2259 for these pointers being NULL to various places around the
2260 code. Affected file silcd/server.c.
2262 * Added client->data.registered == TRUE checks to various
2263 places around the code to assure that unregistered client's
2264 are not handled when it is not allowed. Affected file
2267 * Added `bool registered' fields to all
2268 silc_idlist_[server|client]_get_* routines to indicate whether
2269 the fetched client needs to be registered or not. Affected
2270 file silcd/idlist.[ch].
2272 * Add your own entry as registered to the ID cache in the
2273 server. Affected file server.c.
2275 * Fixed a bug in silc_server_new_server. The SilcServer was
2276 set as the new server's context instead of SilcServerEntry.
2277 This naturally caused some weird bugs.
2279 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2281 * Do not delete the channel rekey task when adding it
2282 for in silc_server_create_channel_key.
2284 * Changed the silc_server_create_channel_key to return
2285 TRUE or FALSE to indicate the success of the channel key
2288 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2290 * Fixed MSVC++ project files and added missing files to
2291 Makefiles under win32/.
2293 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2295 * Do not add TCP_NODELAY flag if the operating system
2296 does not have it defined. Affected files are
2297 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2299 * Fixed buffer overflow from Irssi SILC Client. Affected
2300 file irssi/src/fe-common/core/themes.c.
2302 * Fixed double free in client library in the file
2303 lib/silcclient/client.c when disconnecting from server.
2305 * Applied double free patch from cras to Irssi SILC client.
2306 Affected files irssi/src/core/[modules/expandos].c
2308 * Fixed the disconnection handling to Irssi SILC Client.
2309 The application must call silc_client_close_connection
2310 in ops->connect client operation in case of failure of
2311 the connection. Affected file is
2312 irssi/src/silc/core/client_ops.c.
2314 * Do not set sock->protocol to NULL in the function
2315 silc_client_close_connection after executing the protocol's
2316 final callback since the sock might not be valid anymore.
2317 Affected file lib/silcclient/client.c.
2319 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2321 * Do not enable SILC_THREADS if the linking with libpthread
2322 did not happen. Affected file configure.in.pre.
2324 * Added notion to protocol specification that server must
2325 verify the sent authentication payload with CMODE when
2326 setting the channel founder key. Implemented it to the
2327 server. Affected file silcd/command.c.
2329 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2331 * Added _EXTRA_DIST SILC distribution variable to the
2332 distributions file. It is used to conditionally add extra
2333 files or directories to the specific distribution. Affected
2334 files ./prepare, Makefile.am.pre and distributions.
2336 Removed the `_' from the start of the distribution names.
2339 * Added README.WIN32 for instructions to compile the Toolkit
2342 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2344 * Fixed a double free in disconnection in the server. Affected
2345 file is silcd/server.c.
2347 * Fixed the lib/silcske/groups.c to work now also with GMP
2348 MP library. The string conversion did not work when using
2349 specific base and the base is indicated in the string as well.
2351 * Created win32/ directory which now includes MSVC++ specific
2352 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2353 It will appear only in the toolkit distribution
2355 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2357 * Changed the key material distribution function in case when
2358 the hash output is too short. The data is now concatenated
2359 a bit differently than it used to. Made the change to the
2360 SKE protocol specification.
2362 * Added better GMP detection to configure.in.pre. A patch
2365 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2367 * Fixed a minor bug in SKE that might cause some problem on
2368 some platforms. Affected file lib/silcske/silcske.c.
2370 * Added the cookie checking for initiator in the SKE. It checks
2371 that the responder returns the sent cookie unmodified. The
2372 affected file is lib/silcske/silcske.c. Added new SKE
2373 error type INVALID_COOKIE that can be sent during the
2374 negotiation. Fixed some memory leaks as well.
2376 * Added the "invalid cookie" error message to Irssi SILC client's
2379 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2381 * Added `task_max' field to the SilcClientParams to indicate
2382 the maximum tasks the scheduler can handle. If set to zero,
2383 default values are used. Affected file lib/silcclient/silcapi.h.
2385 * Fixed memory leaks in silc_client_close_connection. Affected
2386 file lib/silcclient/client.c.
2388 * Added silc_client_del_client_entry to client library to free
2389 all memory of given client entry. Affected file is
2390 lib/silcclient/idlist.[ch].
2392 * Added new functions silc_client_del_channel and
2393 silc_client_del_server to delete channel and server entries.
2394 Affected file lib/silcclient/[silcapi.h/idlist.c].
2396 * Removed silc_client_del_client_by_id from silcapi.h.
2398 * Fixed the INFO command to return the server's own info
2399 correctly when querying by Server ID. Affected file is
2402 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2404 * Removed the non-blocking settings in WIN32 code in the
2405 silc_sock_[read/write] and added SleepEx instead. Affected
2406 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2407 of input data is now checked with FIONREAD and ioctlsocket.
2409 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2411 * Call silc_schedule_task_del_by_context in the
2412 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2413 Affected file lib/silccore/silcprotocol.c.
2415 * Call silc_protocol_cancel for active protocols in the
2416 silc_server_close_connection if the funtion
2417 silc_server_free_sock_user_data has not been called.
2418 Affected file silcd/server.c.
2420 * Generic tasks cannot be deleted using the del_by_fd
2421 task deleting function since generic tasks does not match
2422 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2424 * Added a notion to SILCOPER help file that the SILCOPER works
2425 only on router server, not on normal server.
2427 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2429 * Added for WIN32 support for the new scheduler as well.
2430 Affected file lib/silcutil/win32/silcwin32schedule.c.
2432 * Fixed the SHA1 implementation to work on various platforms.
2434 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2436 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2437 API. It is part of the scheduler now. Everything else is
2438 as previously but some functions has changed their names.
2439 Checkout the lib/silcutil/silcschedule.h for the interface.
2440 Updated all applications to use the new interface. Affected
2441 files are lib/silcutil/silcschedule.[ch].
2443 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2445 * Found a bug in the SKE implementation. The HASH value,
2446 specified by the protocol, was not computed correctly. The
2447 public key of the responder was not added to the computation
2448 even though it is mandatory. Affected file lib/silcske/silcske.c.
2449 This unfortunately causes incompatibilities with older
2450 clients and servers.
2452 * Added WIN32 specific network init and uninit functions:
2453 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2454 the Winsock2. Affected file lib/silcutil/silcnet.h and
2455 lib/silcutil/win32/silcwin32net.c.
2457 * Set the socket always to nonblocking mode on WIN32 after
2458 reading data or writing data. Affected file is
2459 lib/silcutil/win32/silcwin32sockconn.c.
2461 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2463 * Fixed various compilation problems under WIN32. Affected
2464 files lib/silcutil/win32/silcwin32thread.c and
2465 lib/silcutil/win32/silcwin32schedule.c.
2467 * Removed all _internal.h #includes from public header
2468 files. Internal headers must never be included from
2471 Removed also the lib/silcske/payload_internal.h file.
2473 * All include files that may be needed (public and some others
2474 included by the public headers) by application developers are
2475 now copied to the ./includes directory. It does not copy any
2476 internal headers. Affected file Makefile.defines.pre and all
2477 Makefile.am's under lib/ and subdirs.
2479 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2481 * Do not change the ~/.silc directory's permissions automatically.
2482 Affected file irssi/src/silc/core/clientutil.c.
2484 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2486 * Do not cancel the protocol in silc_server_close_connection
2487 it might cause recursion. Now cancelled in the function
2488 silc_server_free_sock_user_data. Affected file silcd/server.c.
2490 * Fixed the silc_server_remove_clients_by_server to regenerate
2491 the channel keys correctly finally. Added also new function
2492 silc_server_remove_clients_channels to actually do it.
2493 Affected file silcd/server.c.
2495 * Fixed the silc_server_new_channel to not crash by giving
2496 wrong router to the new channel. Affected file is
2497 silcd/packet_receive.c.
2499 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2501 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2502 which is given as argument to the silc_client_alloc now.
2503 It can be used to configure the client and set various parameters
2504 that affect the function of the client.
2506 * The USERS command in server did not check whether the channel
2507 is private or secret. Affected file silcd/command.c.
2509 * Added new argument to the USERS command in protocol specification.
2510 The USERS command now can take the channel name as argument
2511 as well. Added support for this in client and server and
2512 updated the protocol specs.
2514 * Completed the GETKEY command in client. It can be now used
2515 to fetch also servers public key not only some clients.
2516 Affected files lib/silcclient/command[_reply].c.
2518 * Added silc_client_get_server to return server entry by the
2519 server name. Affected files lib/silcclient/silcapi.h and
2522 * Redefined the IDENTIFY command in protocol specification to be
2523 more generic. It now can be used to query information about
2524 any entity in the SILC Network, including clients, servers and
2525 channels. The query may be based either the entity's name
2526 or the ID. Added support for this in both client and server.
2528 Affected files silcd/command.c and lib/silcclient/command.c
2529 and command_reply.c.
2531 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2532 the _from_client and _from_server functions. Affected file
2535 * Added silc_client_get_channel_by_id_resolve to the file
2536 lib/silcclient/silcapi.h to resolve channel information by
2537 its ID. Added also silc_client_get_channel_by_id that
2538 does not resolve it from the server.
2540 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2542 * Added SilcServerEntry context into the client library
2543 to represent one server. The INFO command now allocates
2544 these to save the resolved server info. For now on the
2545 client library will also keep information about servers,
2546 connected and resolved with INFO.
2548 The INFO command now allocates the SilcServerEntry context
2549 and saves the server info there. The COMMAND_REPLY in
2550 the INFO now returns the parameters to application in
2551 same order as defined in the protocol specification.
2553 The entries are cached in the client->server_cache.
2555 * The INFO command is now issued after received the Client ID
2556 from the server. Affected file lib/silcclient/client.c.
2558 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2559 to the application as the mode changer might be server.
2560 It is guaranteed that NULL is not returned anymore to the
2561 application. Affected file lib/silcclient/client_notify.c.
2563 The ID Type is now also passed to the application so that
2564 it can check whether the returned entry is SilcClientEntry
2567 Added new function silc_client_get_server_by_id to return
2568 the server entry by ID. Affected files are the
2569 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2571 * Do not create the channel in the Irssi SILC Client when issuing
2572 the JOIN command but when received the sucessful JOIN command
2573 reply. Otherwise the channel might get created even though we
2574 could not join it. The Affected file is
2575 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2577 * Fixed a channel joining bug in router. The router must also
2578 check the channel modes, invite and ban lists etc. when serving
2579 the JOIN command sent by normal server. Affected file is
2580 silcd/command.c. The router now resolves the client's
2581 information from the server who sent the JOIN command if it
2582 does not know it, and processes the JOIN command only after
2585 * Changed the SilcCommandCb to take new argument; void *context2.
2586 Affected file lib/silccore/silccommand.h
2588 The second argument in the command callbacks in the server now
2589 includes the SilcServerCommandReplyContext if the command was
2590 called as pending command callback from the command reply.
2591 Otherwise it is NULL. When called as pending the status of the
2592 command reply will be checked and if it was erronous the
2593 error will be sent to the original sender of the command.
2594 This way the client always receives the error messages even
2595 though the server was actually the one who received the error
2596 when it resent the command to router, for example. Affected
2597 files silcd/command[_reply].[ch].
2599 * Fixed sending WHOWAS command's error message to client if
2600 the requested client could not be found. It was missing.
2603 * Changed the CMODE and CUMODE commands reply arguments in the
2604 protocol specification. The Channel ID is now sent in both
2605 of the commands to identify the channel. Implemented this
2606 new feature to the client and server. Affected files
2607 lib/silcclient/command_reply.c and silcd/command.c.
2609 * Made better checks for invite and ban lists in the JOIN
2610 command in server. Affected file silcd/command.c.
2612 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2614 * The server now performs the incoming host IP/DNS lookup
2615 using the silc_socket_host_lookup and thus does not block
2616 the server anymore. Affected file silcd/server.c.
2618 * Completed the multi-thread support for SILC Scheduler in
2619 the lib/silcutil/silcschedule.c.
2621 * Fixed the configure.in.pre to detect the pthread correctly
2624 * Fixed a deadlock in silc_task_queue_wakeup in the file
2625 lib/silcutil/silctask.c.
2627 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2629 * Added new function silc_schedule_wakeup that is used in
2630 multi-threaded environment to wakeup the main thread's
2631 schduler. It needs to be used when a thread adds a new task
2632 or removes a task from task queues. After waking up, the
2633 scheduler will detect the task queue changes. If threads
2634 support is not compiled in this function has no effect.
2635 Implemented the wakeup mechanism to both Unix and WIN32
2636 systems. Affected files are lib/silcutil/silcschedule.[ch],
2637 lib/silcutil/unix/silcunixschedule.c and the
2638 lib/silcutil/win32/silcwin32schedule.c.
2640 * Added new function silc_task_queue_wakeup to wakeup the
2641 scheduler by the specified task queue. Affected file
2642 lib/silcutil/silctask.[ch].
2644 * The silc_socket_host_lookup_start now wakes up the scheduler
2645 after adding the timeout task. Affected file is
2646 lib/silcutil/silcsockconn.c.
2648 * The silc_socket_host_lookup is synchronous now if the threads
2649 support is not compiled in. However, the callback is still
2650 called asyncronously through the scheduler, anyway. Affected
2651 file lib/silcutil/silcsockconn.c.
2653 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2655 * Added new function silc_socket_host_lookup to perform
2656 asynchronous IP and FQDN lookups for the socket connection.
2657 Affected files lib/silcutil/silcsockconn.[ch].
2659 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2661 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2662 that may or may not compile the mutex support in.
2664 Changed the silc_mutex_alloc interface. It allocates the
2665 mutex now to the sent pointer and returns TRUE or FALSE.
2667 Affected file lib/silcutil/silcmutex.h.
2669 * Wrote the SILC Task Queue interface to support multi-threads.
2670 Affected file lib/silcutil/silctask.[ch].
2672 * Wrote the SILC Scheduler to support multi-threads. Affected
2673 file lib/silcutil/silcschedule.c.
2675 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2677 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2678 in lib/silcutil/win32/.
2680 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2682 * Defined SILC Mutex API and SILC Thread API and implemented
2683 them for Unix. Affected files are
2684 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2685 lib/silcutil/unix/silcunixmutex.c and
2686 lib/silcutil/unix/silcunixthread.c.
2688 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2690 * Fixed the silc_server_remove_clients_by_server's channel
2691 key re-generation. The hash table handling was incorrect
2692 and would not work with many channels. Affected file is
2695 * Fixed some memory leaks around the server code.
2697 * Rewrote the silc_server_get_users_on_channel to support IPv6
2698 based Client ID's. Affected file silcd/server.c.
2700 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2701 specification. However, a separate document must be written
2702 to define the detailed signing procedure and the payload
2703 associated with the flag. Defined the flag to the
2704 lib/silccore/silcchannel.h as well.
2706 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2708 * Changed the dynamic tables to static size tables in the
2709 lib/silccrypt/silchmac.c.
2711 * Removed GCC dependencies from the code. A patch by cras.
2713 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2715 * Do not show the error "Error receiving packet bla bla"
2716 in server if it really was not an error (-2 means that reading
2717 is pending). Affected file silcd/server.c.
2719 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2721 * Fixed a possible crash in silc_server_remove_clients_by_server
2722 in silcd/server.c. Fixed there also some memory leaks.
2724 * Fixed the silc_idlist_replace_client_id. It could replace
2725 wrong key in the hash table. Affected file silcd/idlist.c.
2727 * Do not check whether there are global users on the channel
2728 if the channel->global_users is FALSE. Affected functions
2729 silc_server_remove_from_one_channel and
2730 silc_server_remove_from_channels in silcd/server.c. Also,
2731 do not check if the removed client is local as we can be
2732 sure that global client was not removed from the channel
2733 and checking for global users is not needed.
2735 * The silc_server_remove_clients_by_server now re-generates
2736 the channel keys correctly for those channels that had
2737 clients removed from them. Affected file silcd/server.c.
2739 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2741 * Found the reason of random crashes in the server. We weren't
2742 ignoring the SIGPIPE signal (which can be sent in write())
2743 and it crashed the server. Affected file silcd/silcd.c.
2745 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2747 * Assure that sock->user_data is not NULL in the function
2748 silc_server_packet_send in silcd/packet_send.c.
2750 * Disconnect the remote connection if it could not be added
2751 to any ID lists in the server. The affected file is
2754 * Check in silc_server_packet_send[_real/dest] that the
2755 socket is not disconnecting and ignore the data if it is.
2756 Affected file silcd/packet_send.c.
2758 * Define inline to __inline on native WIN32 compilation.
2759 Affected file includes/silcwin32.h.
2761 * Added some explicit type casts for inline code since MSVC
2762 require them. Affected files lib/silcutil/silcbuffer.h,
2763 lib/trq/silcdlist.h and lib/trq/silclist.h.
2765 * Print warning in log files from now on if the packet
2766 decryption fails. Affected file silcd/server.c.
2768 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2770 * Changed the `say' client operation's interface to accept
2771 new `type' argument to indicate the type of the message sent
2772 by the library. The application may filter the library's
2773 messages according the type. The affected file is the
2774 lib/silcclient/silcapi.h.
2776 * Added two new functions to lib/silcclient/silcapi.h:
2777 silc_client_del_client and silc_client_del_client_by_id.
2778 Affected file lib/silcclient/idlist.c.
2780 * Moved the clientincludes.h from includes/ to silc/ and
2781 serverincludes.h from includes/ to silcd/.
2783 * The modes for the CMODE and CUMODE are now passed as
2784 uint32 for application with COMMAND_REPLY. The affected
2785 file is lib/silcclient/command_reply.c.
2787 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2789 * /WHOIS without arguments shows client's own information.
2790 Affected file lib/silcclient/command.c.
2792 * Changed PING to not accept any arguments. The specs
2793 says that client can ping only the connected server so
2794 requiring an argument is not needed. Affected file is
2795 lib/silcclient/command.c.
2797 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2799 * Fixed a fatal bug in private message sending and reception
2800 encryption and decryption when using private message keys.
2801 The implementation was incorrect and did not follow the
2802 specification. It causd that some of the message were
2803 lost since it did not use the sending and receiving keys
2804 as the protocol suggests. This has been fixed and will cause
2805 incompatibilities with older clients when sending private
2806 message encrypted with private message keys. Affected files
2807 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2808 and various other in Irssi SILC Client.
2810 Added `responder' boolean argument to the functions
2811 silc_client_add_private_message_key[_ske] to indicate when
2812 the key is added as responder or initiator of the key
2815 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2817 * Removed the silc_ske_check_version function and created
2818 a SilcSKECheckVersion callback. Added also a function
2819 silc_ske_set_callbacks that is now used to set all SKE
2820 callbacks. The callback functions are not given to
2821 the SKE functions anymore, but this function is used to
2824 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2826 * Added `silc_version' argument to the silc_client_alloc
2827 to define the version of the application for the library.
2828 The library will use the version string to compare it
2829 against the remote host's (usually a server) version
2830 string. Affected file lib/silcclient/silcapi.h
2832 * Added the KE protocol context to Key Agreement context
2833 in client library so that we can abort the SKE if it
2834 is in process when we get timeout. Affected file is
2835 lib/silcclient/client_keyagr.c.
2837 * Do not resolve the client ID forever if it returns in the
2838 first time that such client does not exist. This was done
2839 for example with private message. Affected file is
2840 lib/silcclient/client_prvmsg.c.
2842 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2844 * Do not add regex.h for WIN32. The affected file
2845 includes/silcincludes.h.
2847 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2848 not work yet 100%. It generates the DLL's automatically
2849 when compiling with --with-win32 under cygwin.
2851 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2853 * lib/contrib/regex.c is not compiled on WIN32.
2855 * Added silc_net_get_socket_opt function to the
2856 lib/silcutil/silcnet.h.
2858 * Added includes/silcwin32.h for WIN32 specific includes
2861 * Do not use ptime structure or any of the posix process
2862 functions on WIN32 in lib/silccrypt/silrng.c.
2864 * Added silc_gettimeofday to provide generic function
2865 for struct timeval on all platforms. Added the function
2866 to lib/silcutil/silcutil.h.
2868 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2870 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2871 library as they clearly belong there. As a plus side we
2872 can make the actual socket connection routines platform
2875 Added also new generic function silc_socket_read and
2876 silc_socket_write (that used to be silc_packet_[read/write].
2877 The implementation of these are platform specific.
2879 * Added WIN32 specific routines of silc_socket_[read/write]
2880 to lib/silcutil/win32/silcwin32sockconn.c.
2882 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2884 * Added preliminary support for native WIN32 compilation under
2885 cygwin (using the -mno-cygwin option for GCC) to the
2886 ./configure.in.pre. The --with-win32 now prepares the
2887 compilation for native WIN32.
2889 * Rewrote the SILC Scheduler interface in the file
2890 lib/silcutil/silcschedule.h. The scheduler is now context
2891 based and does not have anymore any global static scheduler.
2892 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2893 and created lib/silcutil/win32 directory for WIN32 based
2896 * Added Unix specific network routines to the
2897 lib/silcutil/unix/silcunixnet.c and the old
2898 lib/silcutil/silcnet.c includes now only generic routines.
2900 Added WIN32 specific network routines to the
2901 lib/silcutil/win32/silcwin32net.c.
2903 * Added Unix specific utility functions from the
2904 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2906 * Added WIN32 SILC Scheduler to the file
2907 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2910 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2912 * Do not handle JOIN notify in the server if the target client
2913 is not registered (idata->registered == FALSE). The affected
2914 file is silcd/packet_receive.c.
2916 * Update the nickrec->founder in event_cumode in the Irssi SILC
2917 client. Affected file irssi/src/silc/core/silc-channels.c.
2919 * Fixed the CUMODE_CHANGE notify handling in the server when
2920 server and router are announcing their clients on channels.
2921 Now the mode changes are saved and notified correctly. The
2922 affected file is /silcd/packet_receive.c.
2924 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2925 They really did not replace the cache entry in the ID Cache.
2926 Now they do that. Affected file silcd/idlist.c.
2928 * Fixed the KICK notify handling in the Irssi SILC client to
2929 update the channel records so that the kicked client does not
2930 appear to be on the channel. The affected file is
2931 irssi/src/silc/core/silc-channels.c.
2933 * Always update the conn->current_channel when executing command
2934 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2936 * Fixed the KILL notify handling in Irssi SILC client to remove
2937 the killed client on all channels.
2939 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2941 * Fixed the silc_parse_command_line to remove extra spaces
2942 from the start and end of the arguments. Affected file is
2943 lib/silcutil/silcutil.c.
2945 * Cancel and free any active protocol in the function
2946 silc_server_close_connection. Affected file silcd/server.c.
2948 * Cancel and free any active protocol in the function
2949 silc_client_close_connction. Affected file is
2950 lib/silcclient/client.c.
2952 * Do not execute the KILL command for clients that are in
2953 history (ie. they are not in the network). Affected file is
2956 * Fixed KILL notify handling, client does not crash anymore.
2957 Affected file irssi/src/silc/core/silc-channels.c.
2959 * Reduced the default packet buffer size from 2048 to 1024 in
2960 lib/silccore/silcpacket.c.
2962 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2963 counter to the SKE context that is incresed when the SKE library
2964 performs async operation outside the library. If the outside
2965 process frees the SKE context and FREED status will be set
2966 and the library will detect after the sync operation that the
2967 libary is freed. The affected files are
2968 lib/silcske/silcske[_status].[ch].
2970 * Resolve the client entry information in the function
2971 silc_client_channel_message to assure that NULL pointer is not
2972 passed as client entry to the application. */
2974 * Fixed the task timeout calculation to assure that there is
2975 never negative timeouts. The affected file is
2976 lib/silcutil/silcschedule.c.
2978 * Fixed the channel user mode notification sending in server.
2979 It was sent point-to-point to the router (or to server by router)
2980 but it needs to be destined to a channel. The routines now
2981 supports sending the channel user mode notifys to the channels
2982 when announcing clients and channels. Affected files are
2983 silcd/server.c and silcd/packet_receive.c.
2985 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2986 It did not actually replace the old channel entry in the cache.
2987 Affected file lib/silcclient/client_notify.c.
2989 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2991 * Fixed a possible crash in silc_packet_send_prepare. It now
2992 assures always that there is enough space in the buffer and
2993 at the tail area of the buffer (for MAC).
2995 Fixed the inbound buffer reallocation in silc_packet_read.
2996 It was old code and did not handle the reallocation correctly.
2999 The affected file is lib/silccore/silcpacket.c.
3001 * Fixed buffer overflow in silc_parse_nickname in the file
3002 lib/silcutil/silcutil.c.
3004 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3006 * make install generates new server keys only if there is not
3009 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3011 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3012 Added check that if the NOREPLY is set then we will not send
3013 the away message. This avoids infinite loop of away messages
3014 if both clients are away. The affected file is
3015 lib/silcclient/client_prvmsg.c.
3017 * Fixed client crash if /NICK was given without arguments.
3018 Affected file lib/silcclient/command.c.
3020 * Server does not send the invite list in INVITE command back
3021 to the client if the list was not altered. Added this notion
3022 to the protocol spec as well. Affected file silcd/command.c.
3024 Fixed possible crash in INVITE command by checking the
3025 value of silc_server_get_client_route command.
3027 * Fixed the INVITE notify type handling. The arguments are now
3028 taken in correct order and client does not crash. The affected
3029 file is irssi/src/silc/core/silc-channels.c.
3031 Removed the "Inviting xxx to channel" message from the
3032 client library away and let the application handle it.
3033 Affected file lib/silcclient/command.c. Added that message
3034 to Irssi SILC client's message formats.
3036 * Fixed CMODE command crash in client. It now checks the
3037 amount of arguments correctly and does not crash. The affected
3038 file is lib/silcclient/command.c.
3040 * Do not create new channel automatically in silc_channels_join
3041 but check whether the channel by that name already exists.
3042 Affected file irssi/silc/core/silc-channels.c.
3044 * Do not send the SERVER_SIGNOFF to router if the disconnected
3045 entity was the router. Affected file silcd/server.c.
3047 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3048 SILC client as it was missing from there.
3050 Added the handling of the KICK notify to the Irssi SILC client
3051 as it was missing. Added "you have been kicked" message to
3052 Irssi SILC client's message modules formats.
3054 Added the handing of the KILL notify to the Irssi SILC client
3055 as it was missing. Added the kill message module formats
3058 The affected file is irssi/src/silc/core/silc-channels.c.
3060 * The router did not save the channel mode the server announced.
3061 Affected file silcd/packet_receive.c.
3063 * Fixed a possible crash in INFO command in server. If the
3064 server did not provide the server info it crashed. Affected
3065 file silcd/command.c.
3067 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3069 * Fixed the GETKEY command in the server to check also the
3070 global list. Otherwise the GETKEY would not work correctly
3071 in normal SILC server. Affected file silcd/command.c.
3073 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3075 * Fixed GETKEY crash, it crashed if the command did not succseed.
3077 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3079 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3080 is now real and not just an macro interface to GMP.
3082 Removed the entire GMP from the source tree and imported new
3083 NSS MPI library instead. Reason for removing GMP is that it is
3084 extremely large and compiles extremely slow. The NSS MPI
3085 is only a few files and compiles in less than 10 seconds.
3086 The speed is also about the same as GMP. The MPI is imported
3087 to lib/silcmath/mpi.
3089 If the system has GMP installed we will still use the GMP.
3090 If it is not then the NSS MPI will be compiled.
3092 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3094 * Merged a long nickname (127 characters long) crash bugfix from
3095 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3097 * Merged a freed memory reference bugfix from Irssi CVS tree.
3098 Affected file irssi/src/core/commands.c.
3100 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3102 * Added the server's public key sving and verification to the
3103 server when performing the SKE. This was missing and the
3104 remote server's (or router's) public key was accepted without
3105 checking whether we have it previously or trust it at all.
3106 Affected file silcd/protocol.c.
3108 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3110 * Check in the silc_server_timeout_remote if protocol is active
3111 and make sure that the protocol's final callback is called so
3112 that all memory if freed. Affected file silcd/server.c.
3114 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3116 * silc_server_whois_send_reply crashed the server if the nickname
3117 was 127 characters long. Affected file silcd/command.c.
3119 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3121 * Added sanity check to the silc_server_new_client. If the hostname
3122 is provided inside username then check that the provided hostname
3123 really is the same as the resolved one. If the hostname was not
3124 resolved then check it from the public key. Affected file is
3125 silcd/packet_receive.c.
3127 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3128 if the server disconnected us and the connection is not valid
3129 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3131 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3132 the library to the lib/silcutil/silcutil.[ch].
3134 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3136 * Close log file after open. Affected file
3137 lib/silcutil/silclog.c.
3139 * Check whether sock == NULL in silc_client_send_packet and return
3140 if it is. Affected file lib/silcclient/silcclient.c.
3142 * Check rec->entry == NULL in the Irssi SILC Client before
3143 sending the channel message. Affecte file is
3144 irssi/src/silc/core/silc-servers.c.
3146 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3148 * Merged a splitted window bugfix from Irssi CVS tree. The
3149 affected file is irssi/src/fe-text/textbuffer-view.c.
3151 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3152 It did not print nickname.
3154 * Improved the distributions system a bit.
3156 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3158 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3159 irssi/src/fe-text/gui-window.c.
3161 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3162 to in-active server. The affected file is
3163 irssi/src/silc/core/client_ops.c.
3165 * Resolve the client in USERS command reply if the entry does
3166 not have username resolved. The affected file is
3167 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3168 command to WHOIS command to really resolve stuff. The USERS
3169 is not used any more in any critical section so WHOIS can
3170 be used even though it might be slower than IDENTIFY.
3172 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3175 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3177 * Changed the protocol API a bit more consistent in the
3178 lib/silccore/silcprotocol.[ch].
3180 * Changed the following headers to ROBODoc format:
3182 lib/silccore/silcpayload.h
3183 lib/silccore/silcprotocol.h
3184 lib/silccore/silcsockconn.h
3186 All core library headers are now formatted.
3188 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3190 * Fixed a bug in Irssi SILC client; do not show that you are
3191 server/router operator if you really are not. Affected file is
3192 irssi/src/silc/core/client_ops.c.
3194 * Renamed silc_command_free_payload to silc_command_payload_free.
3195 Affected file lib/silccore/silccommand.h
3197 * Added silcmath.h to include the prototoypes of various routines
3198 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3201 * Changed the following headers to ROBODoc format:
3203 lib/silccore/silcchannel.h
3204 lib/silccore/silccommand.h
3205 lib/silccore/silcid.h
3206 lib/silccore/silcidcache.h
3207 lib/silccore/silcmode.h
3208 lib/silccore/silcnotify.h
3209 lib/silccore/silcpacket.h
3210 lib/silcmath/silcmath.h
3212 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3214 * Added checking to the server code not to start the server if
3215 ciphers and stuff are not configured properly. Affected files
3216 silcd/serverconfig.[h] and silcd/server.c.
3218 * Changed the layout of the header files of the public interfaces
3219 in the SILC libraries. The new layout supports ROBODoc
3220 documentation tool (and some others) so that it is easy to create
3221 a library reference manual. All the other headers and source
3222 code must still follow the CodingStyle document. Also source
3223 code must not include these ROBODoc stuffs, only the headers.
3224 Furthermore, all public interface headers must now be named
3225 by using `silc' prefix, example: silcapi.h, silccipher.h.
3226 Some files were renamed due to this. All the other headers
3227 must not be used as public interfaces. I will update the
3228 CodingStyle document later. Changed following headers, so far:
3230 lib/silcclient/silcapi.h
3231 lib/silccore/silcauth.h
3232 lib/silccore/silcprivate.h
3233 lib/silccrypt/silcdh.h
3235 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3239 * Removed silc_client_packet_send_flush from the client library
3240 as it is not needed. Affected file lib/silcclient/client.[ch].
3242 * Added printing of message of unresolved authentication method
3243 to the Irssi SILC client. Added it to the module formats.
3244 Removed the same message from the client library.
3246 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3248 * Added new distribution feature, DISTLABEL. Every distribution
3249 can define own preprocessor label that can be used in the
3250 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3251 file distributions, acconfig.h.pre and prepare.
3253 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3255 * Added Makefile.defines_int to include the actual definitions
3256 for Makefile.defines.in. Tested the new distribution system,
3257 created distributions and tested installation.
3259 * Added AWAY message printing to the Irssi SILC client. Added
3260 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3262 * Added SCONNECT command to call the SILC's CONNECT command.
3263 Cannot use CONNECT directly since Irssi uses that internally.
3264 Affected file irssi/src/silc/core/silc-servers.c.
3266 Added ACTION local command. It is same as ME command but takes
3267 the channel as mandatory argument.
3269 Rewrote some of the Irssi's help files to suite for SILC
3272 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3274 * Added Makefile.defines[.in] that should for now on be included
3275 in all Makefile.am file in the source tree. That file includes
3276 all common compilation definitions for SILC source tree.
3278 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3280 * Minor changes to the ./prepare script to change the package
3281 name according the distribution name to the configure.in.
3283 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3285 * Created new distribution system. Added file `distributions'
3286 that defines all the distributions that can be created out of
3287 the SILC source tree. The ./prepare script now reads that
3288 file to determine how to prepare the distributions. The
3289 first argument to the ./prepare is the name of the distribution
3290 and second is the version of the distribution. If given
3291 without arguments it creates the default (toolkit) distribution
3292 with the default version (defined in ./prepare).
3294 All Makefile.am files that are subject to the distributions
3295 are now named as Makefile.am.pre. These are ./Makefile.am
3296 and lib/Makefile.am. Others may be changed later.
3298 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3300 * Added invite list, ban list, some key management and connection
3301 error message printing to module formats in the Irssi SILC client.
3303 * Added new silc_client_set_away_message to set the away message
3304 that is back to the person who sent private message. The
3305 affected file lib/silcclient/silcapi.h and the
3306 lib/silcclient/client_prvmsg.c.
3308 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3310 * Fixed the private message sending in the Irssi SILC client,
3311 added local command KEY to the Irssi SILC client.
3313 Added key management and key agreement message formats to the
3314 irssi/src/fe-common/silc/module-formats.[ch].
3316 Added USERS (alias WHO) printing, server/router operator
3317 indication and LIST command printing to the module formats.
3319 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3321 * Fixed channel joining notify handling, cumode notify handling
3322 from Irssi SILC client.
3324 * Added SILC specific module-formats to the Irssi SILC client so
3325 that SILC specific message hilighting, colors etc is possible.
3326 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3328 Added channel mode, channel user mode, actions, notices,
3329 whois and whowas printing to the the module-formats.c.
3331 * Fixed a bug in channel deletion in the server. The channel
3332 is not left to the cache even if the channel founder auth mode
3333 is set when there are no users anymore on the channel. Affected
3334 file silcd/server.c.
3336 * The silc_net_localhost now resolves the entire hostname including
3337 the domain name. Affected file lib/silcutil/silcnet.c.
3339 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3341 * Changed the ask_passphrase client operation to be ascynchronous.
3342 It has now a completion callback and a context that the
3343 application must call after it has got the passphrase from
3344 the user. Affected files lib/silcclient/silcapi.h,
3345 lib/silcclient/protocol.c, lib/silcclient/command.c and
3348 Added SilcAskPassphrase callback that the application calls
3349 to deliver the passphrase to the library.
3351 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3352 The public key verification and especially a certificate
3353 verification is asynchronous procedure.
3355 Added new SILC_SKE_STATUS_PENDING status to indicate the
3356 request is pending and a callback will be called to finalize
3359 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3360 indicate that remote end did not send its public key (or
3361 certificate), even though we require it. Added check for this
3362 condition in the SKE. This was a security bug, now fixed.
3364 Defined new SilcSKEVerifyCbCompletion callback that is called
3365 when the verification process is completed.
3367 The affected files lib/silcske/silcske_status.h and
3368 lib/silcske/silcske.[ch].
3370 * Changed the verify_public_key client operation to be async
3371 as well. Defined SilcVerifyPublicKey callback that is used to
3372 indicate the success of the public key verification process.
3374 Changed the server and client to use the new async client
3377 * Changed the Irssi SILC client's internal scheduler to be called
3378 twice as many times as it used to be. As a result the client
3379 should be a bit faster now. Affected file is
3380 irssi/src/silc/core/silc-core.c.
3382 * Added support to Irssi SILC client of asynchronous public key
3383 verification and passphrase inquiry. Affected file is
3384 irssi/src/silc/core/silc-core.c.
3386 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3388 * Do not say "You have left channel %s" in client library.
3389 Moved it to the application. Affected files are
3390 lib/silcclient/command.c and silc/client_ops.c.
3392 * Fixed silc_client_get_clients. Command context was not
3393 duplicated and was freed memory in the callback. Affected
3394 file lib/silcclient/idlist.c.
3396 * Do not say "you are now talking..." on JOIN command in the
3397 client library. The appliation must handle it.
3399 * Do not say ".. changed topic to" in command reply in the
3400 client libary. The application must handle it.
3402 * Fixed TOPIC command sending in the client library.
3404 * Fixed a memory leak in silc_client_command_free in the file
3405 lib/silcclient/command.c.
3407 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3409 * Imported a modified version of Irssi client to the source tree.
3410 The Irssi will be used to create a new client called
3411 Irssi SILC. Imported to irssi/.
3413 Added silc_core_init_finish function to the Irssi. Affected
3414 file irssi/configure.in.
3416 A lot changes in the Makefile.ams around the irssi tree.
3418 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3420 * Do not rehash if the new size is same as the old size of the
3421 hash table, in the silc_hash_table_rehash*. The affected file
3422 lib/silcutil/silchashtable.c.
3424 * Replaced hash_table_del_by_context calls from the server
3425 (when channel->user_list and client->channels) to the
3426 hash_table_del as it is sufficient and faster.
3428 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * Added silc_hash_table_list, silc_hash_table_get and the
3431 SilcHashTableList structure to provide an alternative way to
3432 traverse the hash table. The affected files are
3433 lib/silcutil/silchashtable.[ch].
3435 * Changed the server's idlist routines to use the hash table
3436 routines to optimize the code.
3438 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3440 * Replaced the client entry's `channel' list and channel entry's
3441 `user_list' list to hash tables for optimized lookup. Changed
3442 the code to use the hash table interface around the code.
3443 Affected file lib/silcd/idlist.[ch].
3445 * Added `auto_rehash' boolean argument to the function
3446 silc_hash_table_alloc to indicate whether the hash table should
3447 auto-rehash when it thinks is appropriate time. It will
3448 increase the hash table size if the there is twice as much
3449 entries in the table than the size of the table, and will
3450 decrease the size if there are twice as less entries than
3451 the size of the table.
3453 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3455 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3457 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3459 * silc_idcache_purge_by_context deletes the entry now by context
3460 as it is supposed to do. Affected file lib/silccore/idcache.c.
3462 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3463 client is not anymore valid (WHOWAS givens the info) and not
3464 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3466 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3468 * Removed the `data' and `data_len' arguments from the ID Cache
3469 interfaces and added `name' argument. ID Cache does not handle
3470 anymore the binary data only a names associated with given ID.
3472 * When hashing a Client ID with silc_hash_id the entire ID is
3473 not hashed anymore, instead only the hash of the Client ID is
3474 hashed. This way we can access the Client ID from the cache
3475 with Client ID but with the hash of the ID (which is a hash of
3476 the nickname) as well without any difference in performance.
3478 Added also silc_idcache_find_by_id_one_ext to do one on one
3479 searching when we have the actual ID. Added also function
3480 silc_hash_client_id_compare. The affected files are
3481 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3483 * When hashing the name associated with a ID it is always done
3484 in lowercase. This way we can access the cache without worrying
3485 about case-sensitivity, even though, for example nicknames are
3488 * Fixed a bug in server with channel message sending. It put
3489 wrong ID type as destination ID. The affected file
3490 silcd/packet_send.c.
3492 * silc_idcache_del_by_context now deletes from all hash tables
3493 by context. Affected file lib/silccore/idcache.c.
3495 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3497 * Changed the client library to use the new ID Cache interface.
3498 Changes around the source tree.
3500 * Added silc_hash_table_rehash_ext to rehash with specific
3501 hash function. Affected file lib/silcutil/silchashtable.[ch].
3503 * Added silc_hash_string_compare to compare two strings in the
3504 hash table. Affected file lib/silcutil/silcutil.[ch].
3506 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3508 * Added new function silc_idcache_del_by_context into the
3509 lib/silccore/idcache.[ch].
3511 * Changed the server's ID list routines to use the new ID Cache
3512 interface. Changes around the source tree.
3514 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3516 * Added silc_hash_table_del[_by_context]_ext functions in to the
3517 lib/silcutil/silchashtable.[ch].
3519 Removed silc_hash_table_find_all* routines and added new
3520 silc_hash_table_find_foreach to replace them.
3522 Added silc_hash_table_replace_ext function as extended
3523 replacing function. Separated the simple hash table interface
3524 from the extended hash table interface in the file
3525 lib/silcutil/silchashtable.h.
3527 * Fixed minor bugs and changed it to use some of the new
3528 hash table functions in lib/silccore/idcache.c
3530 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3532 * Added new function silc_hash_table_find_all to return all keys
3533 in the hash table by the specified key. As the hash table is
3534 collision resistant it also makes it possible to have several
3535 duplicate keys in the hash table. This function may be used to
3536 find all of the keys from the hash.
3538 Added user_context arguments to the SilcHashFunction,
3539 SilcHashCompare and SilcHashDestructor to deliver user specified
3542 Added new fuctions silc_hash_table_find[_all]_ext to do
3543 extended lookup with specified hash and compare functions and
3544 specified user contexts.
3546 Added new function silc_hash_table_add_ext to add the key
3547 with specified hash function and user context.
3549 Added new function silc_hash_table_foreach to traverse all
3550 entrys in the hash table. Added SilcHashForeach callback
3553 Added new function silc_hash_table_del_by_context to delete
3554 the entry only if the context associated with the key matches.
3556 Affected files are lib/silcutil/silchashtable.[ch].
3558 * Removed silc_hash_[server/client/channel]_id and added just
3559 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3560 silc_hash_id_compare to compare two ID's using as the hash table
3561 comparison function. Added also silc_hash_data to hash
3562 binary data and silc_hash_data_compare to compare it.
3564 * Removed silc_idlist_find_client_by_hash as it is not needed
3565 anymore. Affected file silcd/idlist.[ch].
3567 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3568 to use internally the SilcHashTable. The new ID Cache is a lot
3569 faster than the old one. Some of the ID Cache interface was also
3570 rewritten and obsolete and stupid functions were removed.
3572 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Added entry_count field to the SilcHashTable to keep the number
3575 of the entries in the table. Implemented the function
3576 silc_hash_table_rehash. Added new function
3577 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3579 Fixed a minor bug in silc_hash_table_free.
3581 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3582 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3583 into the lib/silcutil/silcutil.[ch].
3585 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3587 * Implemented a collision resistant hash table into the
3588 lib/silcutil/silchashtable[ch]. See the header and the source
3589 for the SilcHashTable API.
3591 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3593 * Merged dotconf version 1.0.2 into lib/dotconf.
3595 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3597 * Do not compile anything in lib/silcsim/* if the SIM support
3598 is not enabled. The tree should now compile without problems
3601 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3603 * Compiled the SILC under cygwin. Compiled and tested briefly
3604 without problems. More tests needed. The SIMs didn't compile
3607 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3609 * Fixed possible crash in silc_get_username in the
3610 lib/silcutil/silcutil.c.
3612 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3614 * Fixed a va_arg in silc/client_ops.c.
3616 * Oops, RC5 routines were named AES and caused some problems
3617 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3619 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3621 * Added new SilcIDIP structure into the lib/silccore/id.h and
3622 replaced the old `ip' fields from all SILC ID's to that type.
3623 This is a step towards IPv6 support.
3625 The silc_id_get_len takes now the ID as an extra argument.
3626 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3627 both IPv4 and IPv6 based ID's.
3629 The affected files are lib/silccore/id.[ch] and other files
3630 around the tree using these routines.
3632 * Removed the ID length arguments in server from various
3633 silc_server_send_notify_* routines -> they are not needed
3636 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3638 * Fixed memory leak in silc_encode_pem_file in the file
3639 lib/silcutil/silcutil.c.
3641 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3643 * Check minor version as well in the SKE. Affected files are
3644 silcd/protocol.c and lib/silcclient/protocol.c.
3646 * Added --identifier option to the server so that an identifier
3647 can be when creating the public key for the server. Affected
3648 file is silcd/silcd.c.
3650 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3651 lib/silccrypt/silcpkcs.c.
3653 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3655 * Register default ciphers and stuff when using -C option with
3656 the server. Affected file sildc/silcd.c.
3658 * Put back the servers public key filename format, it is better
3659 than the new one. For now, the client keys are saved with the
3660 new filename format. The affected file silc/client_ops.c.
3662 * Implemented the Cipher API for the rest of the ciphers that
3663 did not implement it or implemented it the wrong way.
3665 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3667 * Register default ciphers and stuff when using the -S option
3668 in the client. Affected file silc/silc.c. Same also when
3669 creating new key pair with -C option.
3671 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3673 * Fixed the silc_verify_public_key client operation function to
3674 save the public keys differently. The fingerprint is now
3675 used as filename and not the hostname. This way also the
3676 client keys are saved uniquely and not with hostnames. The
3677 affected file is silc/client_ops.c.
3679 * Trimmed the silc_hash_fingerprint function to remove extra
3680 whitespaces from the end of the fingerprint. The affected
3681 file is lib/silccrypt/silchash.c.
3685 * Added silc_cipher_register_default function to register all
3686 default ciphers. It can be used when configuration files
3687 does not exist and the application does not want any specific
3688 ciphers in any specific order.
3690 The SilcDList is now used as silc_cipher_list dynamically
3691 allocated cipher list. Removed the static list all together
3692 and now all ciphers must be allocated to the dynamic list.
3693 The silc_cipher_alloc routine was changed to check only the
3696 All silc_cipher_* routines that used to return int returns
3699 The affected files lib/silccrypt/silccrypt.[ch].
3701 * The same thing was done to silc_hash_* as for silc_cipher_*
3702 routines. Affected files lib/silccrypt/silchash.[ch].
3704 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3705 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3706 Added also silc_pkcs_[un]register[_default] functions.
3707 Removed the data_context from the PKCS API.
3709 * Added silc_hmac_register_default function to register default
3710 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3711 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3712 to unregister all hmacs at once.
3714 * Register the default ciphers, hash functions, PKCSs and HMACs
3715 if client's configuration file does not exist. The affected
3718 * The client did not load the hash functions from the SIM
3719 modules at all. Added support for this. Affected file is
3720 silc/clientconfig.c.
3722 * When decoding public key with silc_pkcs_public_key_decode, check
3723 the supported algorithm only if PKCS are registered. Affected
3724 file lib/silccrypt/silcpkcs.c. The same was done with the
3725 silc_pkcs_private_key_decode.
3727 * Fixed the SILC List routines to keep the list always in order.
3728 It used to change the list's order when traversing the list but
3729 not it preserves the order. Affected file lib/trq/silclist.h.
3731 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3733 * Added the client library to use the SilcSocketConnection's
3734 reference counter (by silc_socket_dup) to prevent the bug that
3735 the socket object may be freed underneath async operation.
3737 * The name resolv library checking fixes in the configure.in.pre.
3740 * Created new version of the protocol drafts for future
3741 development. The -03 drafts are the ones that will be changed
3742 in the trunk now and the -02 will remain as they are.
3744 * Send list of CUMODE notifys to the router when announcing
3745 the channel users to the router. Affected file silcd/server.c.
3746 If the router receiving channel founder CUMODE for a channel
3747 that already has channel founder it will send CUMODE notify
3748 to the sender to remove the channel founder rights from the
3749 announced client. Affected file silcd/packet_receive.c.
3751 * The CUMODE notify may now use Server ID as well as the entity
3752 who changes the mode. Updated protocool specs.
3754 * Updated INSTALL and README files.
3756 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3758 * New web pages in the http://silc.pspt.fi. The pages was
3763 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3765 * Implemented the [DenyConnectin] config section in the server.
3766 Added silc_server_config_denied_conn to check whether incoming
3767 connection is denied. Affected file silcd/serverconfig.[ch].
3769 * Do not check the ports when checking the incoming configuration
3770 data if the port is 0, meaning any. Affected file is
3771 silcd/serverconfig.c.
3773 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Fixed buffer overflow in silc_string_compare in the file
3776 lib/silcutil/silcutil.c.
3778 * Fixed double free in silc_server_command_leave in the file
3781 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3783 * Fixed the version checking in the server. Affected file is
3786 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3788 * Fixed the configuration data fetching when accepting new
3789 connections in the server. Affected file silcd/server.c.
3791 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3793 * Added `sender_entry' argument to the function
3794 silc_server_packet_relay_to_channel so that we can check
3795 whether some destination actually belongs to the same route
3796 the sender belongs (ie, we must not resend the packet to the
3797 sender). Affected file silcd/packet_send.[ch].
3799 * Added `servername' field to the SilcClientEntry in the server
3800 to hold the name of the server where client is from. Affected
3801 file is silcd/idlist.h.
3803 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Moved the channel message encrypting in the router betwen
3806 router connections from silc_server_channel_message to the
3807 silc_server_packet_relay_to_channel since we want to check
3808 whether we have anybody channel before encrypting anything.
3809 Affected files silcd/packet_[receive/send].c.
3811 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3813 * Fixed the [AdminConnection] server config section to support
3814 multiple entries. Affected file silcd/serverconfig.c.
3816 * Added support into the server to check the validity of the
3817 incoming connection before executing any KE or authentication
3820 * The connection configuration is now saved to the KE and
3821 connection auth protocol contexts and not fetched anymore in
3822 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3824 * The local hosts listenning address and port is also resolved
3825 now when starting the server. We want to have the socket object
3826 to include the real address and port for the listener. Added
3827 new function silc_net_check_local_by_sock into the files
3828 lib/silcutil/silcnet.[ch].
3830 * Fixed a broadcast bug in server -> do not broadcast if we
3833 * Fixed a routing bug. Do not route broadcast packets ever.
3834 Broadcast packets must be processed always and not routed since
3835 they may be destined to some other host than yourself and thus
3836 would get routed without no good reason. Affected file is
3839 * Added function silc_server_config_is_primary_route to check
3840 whether primary router connection has been configured (a router
3841 configuration that we are initiating). If there is not, we
3842 will assume that there is only two routers in the SILC network
3843 and we will use the incoming router connection as our primary
3844 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3846 * Changed the order of the broadcasting. Broadcast _after_ the
3847 packet has been processed not before. Affected file is
3850 * Fixed a [ClientConnection] parsing bug. The port was never
3851 parsed correctly thus resulting to port 0. Affected file
3852 silcd/serverconfig.c.
3854 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3855 argument and did not set the broadcast packet flag. Affected
3856 file silcd/packet_send.c. Fixed same bug in the function
3857 silc_server_send_notify as well.
3859 * If we receive NEW_ID packet for our own ID in the server, ignore
3862 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3866 * Removed the nickname from the Private Message Payload.
3867 Updated the code and the protocol specs.
3869 * Updated protocol specs for submitting to the IETF.
3871 * Tweaked the Random Number Generator a bit. Affected file
3872 lib/silccrypt/silcrng.c. Exported a new function
3873 silc_rng_[global]_add_noise which can be used to add more
3876 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3878 * Do not parse packets with different timeout when protocol
3879 is active -> may cause problem with rekey. Affected file
3882 * When server receives signoff notify it must not create
3883 new channel key if the client is on any channels since the
3884 sender of the signoff notify will create it.
3886 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3888 * Added printing of error messages during SKE protocol from the
3889 failure packet sent by server during SKE. Affected file
3892 * Removed the client's failure_callback handling with timeout
3893 and handle it immediately when received.
3895 * The SKE library returned wrong type in SUCCESS and FAILURE
3896 packets. They must be 32 bit MSB not 16 bit MSB.
3898 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3900 * Ok, rewrote the logic of the re-key and now it seems to work.
3901 I tested it on high traffic with frequent re-keys without
3902 problems. Added hmac_receive (and renamed hmac to hmac_send)
3903 in SilcClientConnection in lib/silcclient/client.h and
3904 in SilcIDListData in silcd/idlist.h. Also, removed the
3905 SilcPacketParserContext's cipher and hmac fields as they are
3906 not needed anymore and actually caused some problems when
3907 the ciphers and hmac's changed underneath the packet parser.
3909 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3911 * If re-key protocol is active then process the incoming packets
3912 synchronously since we must assure that icoming packets encrypted
3913 with the old key is processed before the new keys is set to
3914 use. This is true other packets than for REKEY packets.
3915 Affected file silcd/server.c. The same was done to client library
3916 as well, affected file lib/silcclient/client.c.
3918 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3920 * Fixed bug in client and server to accept the force send if
3921 the packet is send from silc_[server/client]_packet_process
3922 function. Otherwise the packets are never delivered, oops.
3924 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3926 * Disable force sending of packets when REKEY protocol is active.
3927 We must assure that no packet is sent directly when rekey is
3928 performed. All packets must be sent through packet queue.
3929 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3930 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3931 function is silc_[server/client]_packet_send_real to check
3934 * Replaced the SIM paths from example config files to
3935 /usr/local/modules. Also, make install creates now
3936 /usr/local/silc/logs directory to hold all the SILC server
3939 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3941 * Made the configure.in.pre work on Solaris. Patch by salo.
3943 * Made all ciphers compatible with non-x86 machines. Defined
3944 CBC mode macros into lib/silccrypt/ciphers_def.h.
3946 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Fixed the make install.
3950 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * When MAC computation fails the silc_packet_decrypt returned 0
3953 even though it was supposed to return -1. Fixed this. The
3954 affected file is lib/silccore/silcpacket.c.
3956 * Do not replace the config files in /etc/silc (in make install)
3957 if they already exist. Affected file ./Makefile.am.
3959 * Do not send re-key packets immediately but through packet queue.
3960 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3962 * Changed silc_net_check_host_by_sock to return FALSE if the
3963 IP/DNS could not be resolved. Though, it returns the IP address
3964 now even if it could not resolve it (but returns also FALSE).
3965 Affected file lib/silcutil/silcnet.[ch].
3967 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3969 * Added silc_pkcs_decode_identifier to decode the public key's
3970 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3971 Added also silc_pkcs_free_identifier. Added also new context
3972 SilcPublicKeyIdentifier.
3974 * Added -S option to the silc client. It is used to dump the
3975 contents of the specified public key file.
3977 * Changed the PKCS api to return the public key length when
3978 setting the public key.
3980 * Fixed a fatal bug in the public and private key file loading.
3981 Affected file lib/silccrypt/silcpkcs.c.
3983 * Execute the packet parsing for client with zero (0) timeout
3984 if the protocol is active. Affected file silcd/server.c.
3986 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3988 * Made the key generation options to the silcd program. Added
3989 -C option, equivalent to client's option.
3991 * Added new [ServerKeys] config section to the server. It
3992 configures the server's public and private key.
3994 * Defined generic Public Key Payload into the protocol
3995 specification to send specific type of public keys and
3998 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3999 public key or certificate.
4001 * Implemented the GETKEY command to the server and to the
4002 client library and on user interface.
4004 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4006 * Made preliminary `make install' work.
4008 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4010 * Added SilcServerRekey context into silcd/idlist.h.
4012 * Added the PFS support as defined in the specification to the
4013 SKE protocol. Affected files lib/silcske/*.c.
4015 * Added `ske_group' field to the SilcServerRekey context to hold
4016 the number of the SKE group that is used with PFS in re-key.
4017 Affected file silcd/idlist.h.
4019 * Added PFS re-key support to the server. Affected file is
4022 * Added silc_protocol_cancel to cancel execution of the next
4023 state of the protocol. Affected file is
4024 lib/silccore/silcprotocol.[ch].
4026 * Added the re-key support with and without PFS to the client
4027 library. Re-key is performed once in an hour, by default.
4029 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4030 Added silc_client_rekey_callback and silc_client_rekey_final.
4031 Affected files are lib/silcclient/protocol.[ch] and
4032 lib/silcclient/client.[ch].
4034 * Removed the `hmac_key' and `hmac_key_len' fields from the
4035 SilcClientConnection structure; not needed. Affected file is
4036 lib/silcclient/client.h.
4040 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4042 * Do not ask whether user wants to use the negotiated private key
4043 for private messages, just use it. Affected file is
4044 silc/local_command.c.
4046 * Added `send_enc_key' and `enc_key_len' fields to the
4047 SilcIDListData structure since they are needed in the re-key
4048 phase. Affected file is silcd/idlist.[ch].
4050 * Implemented the simple re-key protocol into the server.
4051 Affected files silcd/server.c and silcd/protocol.[ch]. The
4052 re-key will be performed once in an hour, by default.
4054 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4055 Added silc_server_rekey, silc_server_rekey_callback and
4056 silc_server_rekey_final.
4058 * Removed Tunneled flag from the protocol. Updated the code
4059 and the specifications.
4061 * Adde `pfs' field to the SilcIDListData to indicate whether
4062 the PFS is to be performed in the re-key. Affected file is
4065 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4067 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4068 int64 of at least the xintXX size. If void * is less that 4
4069 bytes uint32 * will be used. Defined bool as boolean.
4071 * Changed _ALL_ unsigned long and unsigned int to uint32,
4072 unsgined short to uint16 in the source tree.
4074 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4075 not handle clients that has entry->data.registered == FALSE.
4076 They are not in the network anymore. Affected file is
4079 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4081 * Implemented the sending of the SERVER_SIGNOFF notify in the
4082 server. Affected file is silcd/server.c.
4084 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4085 Added also silc_notify_payload_encode_args into the
4086 lib/silccore/silcnotify.[ch].
4088 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4089 Affected file silcd/packet_receive.c.
4091 * Implemented the SERVER_SIGNOFF notify handling in the client
4092 library. Affected file lib/silcclient/client_notify.c. Also,
4093 implemnted the printing of the SERVER_SIGNOFF info to the
4094 application. Affected file silc/client_ops.c.
4096 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4097 if the deleting was successful. Affected file silcd/idlist.[ch].
4099 * Added support for public key authentication in the connection
4100 authentication protocol in the client library. Affected file
4101 lib/silcclient/protocol.c.
4103 * Changed the server's silc_idlist_get_clients_by_* interface
4104 to support already allocated array so that new entries may be
4105 added to pre-allocated array. Affected file silcd/idlist.[ch].
4106 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4107 and command replies.
4109 * All command reply functions in the server now calls the
4110 pending command callback even if error occured. This way the
4111 error will be delivered to the client as well. Affected files
4112 silcd/command.c and silcd/command_reply.c.
4114 * Fixed INFO command to return local server's info if no server
4115 was provided. Affected file lib/silcclient/command.c.
4117 * Removed RESTART command for good. Updated the code and the
4120 * Rewrote parts of the task system. It is a bit simpler now.
4121 Removed unsued task priorities. The affected files are
4122 lib/silcutil/silctask.[ch].
4124 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4126 * Moved the USERS printing from the library to the application.
4127 Affected files lib/silcclient/command.c and silc/client_ops.c.
4129 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * Added channel key re-key support. The re-key is perfomed
4134 only by the router and is done once in an hour. Added `rekey'
4135 field to the SilcChannelEntry in the server. Affected files
4136 silcd/server.c and silcd/idlist.h.
4138 * Added silc_task_unregister_by_context into the file
4139 lib/silcutil/silctask.[ch].
4141 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4143 * Added SILC_UMODE_GONE mode to indicate when the client is not
4144 present in the SILC network. Added also support to the local
4145 command AWAY that will set this mode. Added support of showing
4146 "xxx is gone" in WHOIS command. The USERS command shows the
4147 gone status as well.
4149 * Fixed setting server and router operator privileges in the
4150 server's UMODE command. Affected file silcd/command.c.
4152 * Merged the SKE KE1 and KE2 payloads into one payload. The
4153 new KE payload is equivalent to the old KE2 payload.
4155 Cleaned up the SKE Start Payload parsing. It now uses the
4156 simple buffer unformatting to do the parsing. A lot faster
4159 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4160 to the SKE that is used to indicate whether both of the SKE
4161 parties should perform authentication. By default only the
4162 responder performs authentication. By setting this flag also
4163 the initiator must do authentication. By default it is unset
4164 since in normal SKE case, client to server connection, only
4165 the responder should do authentication. When doing SKE between
4166 two clients both should perform authentication. Updated the
4167 code and the protocol specs.
4169 * A little fix to IDENTIFY command in the server. Search the
4170 client first by hash not nickname. Affected file is
4173 * Fixed the silc_client_close_connection to support closing
4174 the client to client connections wihtout deleting too much
4175 data. Affected file lib/silcclient/client.c.
4177 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4178 are received if protocol used to be active but is not anymore
4179 the application would crash due to NULL pointer dereference.
4180 Affected files silcd/server.c and lib/silcclient/client.c.
4182 * Added `hash' field to the SilcClientConnection to include
4183 the hash function negotiated in the SKE protocol.
4185 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4186 to set the channel founder authentication data. A client can
4187 claim the founder rights later by providing the authentication
4188 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4189 This way the channel founder can regain the channel founder
4190 privileges even it is left the channel. This works only on
4191 local server and the client must be connected to the same
4192 server to be able to regain the founder rights. Updated the
4193 protocol specs accordingly.
4195 Added support to the CMODE command in the client to set the
4196 founder auth data. Read the README to see how to set it.
4198 Added support to the CUMODE command to claim the founder
4199 rights. Read the README to see how to do it.
4201 Added support for the founder authentication to the Channel
4202 Entry in the server. Affected file silcd/idlist.h.
4204 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4205 server's CMODE command. Affected file silcd/command.c.
4207 * Added the following new functions into lib/silccore/silcauth.[ch]:
4208 silc_auth_get_method and silc_auth_get_data.
4210 * The server now saves the remote hosts public key to the
4211 SilcIDListData pointer. Affected file silcd/protocol.c.
4213 * The normal server now does not remove the channel entry from
4214 the cache if the founder authentication data is set. It used
4215 to remove it if the founder was the last one on the channel on
4216 the server and left the channel. The auth data is saved and
4217 if the channel is re-joined later the old entry is used with
4218 the old auth data. Affected files silcd/command_reply.c and
4221 * Removed the `pkcs' field from the SilcIDListData structure
4222 in the server; it is not used. Affected file silcd/idlist.h.
4224 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4226 * Fixed packet processing on slow links. Partial packets were
4227 never re-processed because the incoming data buffer was cleared
4228 by the application. Application must not directly clear the
4229 sock->inbuf, the packet processing routines handle it. Fixed
4230 this in client library and in server.
4232 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4234 * Fixed the WHOIS and IDENTIFY send reply function to really
4235 check whether to send list or just one entry. Affected file
4238 * Cleaned up the LEAVE command's channel key distribution. The
4239 affected file silcd/command.c.
4241 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4242 can enforce the channel mode as well. In that case the ID
4243 includes the ID of the server. The code now enforces the
4244 mode change if the router have different mode than the server.
4246 * The notify client operation with CMODE_CHANGE notify can now
4247 return NULL client_entry pointer if the CMODE was not changed
4248 by client. Application must check for this.
4250 * Added <Server ID> argument to INFO command to support server
4251 info fetching by Server ID.
4253 * Added silc_server_announce_get_channel_users to get assembled
4254 packets of channel users of the specified channel. Affected
4255 file silcd/server.[ch].
4257 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4258 was freed underneath the ID Cache.
4260 * Re-announce clients when the server received CHANNEL_CHANGE
4261 notify from the router. Affected file silcd/packet_send.c.
4263 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4265 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4266 crashed since it did not handle the fact that there is no cipher
4267 called "3" and didn't check the error condition. Now fixed.
4269 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4270 flag. It can be used to send message requests.
4272 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4274 * Implemented the RESTART command in the client.
4276 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4277 notice type messages. Added notice printing to the user
4280 * The channel keys are not re-generated if the channel's mode
4281 is PRIVKEY, ie private key on the channel exists. Affected
4282 files silcd/server.c and silcd/command.c.
4284 * Fixed a little bug in channel message delivery when channel
4285 private keys are set in the server. Affected file is
4286 silcd/packet_send.c.
4288 * Changed the setting on channel->on_channel = TRUE from the
4289 silc_client_save_channel_key to the JOIN command reply. The
4290 key payload is not received if the private channel key is set.
4291 Affected file lib/silcclient/command_reply.c and the
4292 lib/silcclient/client_channel.c.
4294 * When the CMODE_CHANGE notify is sent and the channel private
4295 key mode is removed the channel key must be re-generated in
4296 other cells as well. Added this support for the router in the
4297 silcd/packet_receive.c.
4299 * Added new local command NOTICE to send notice message on
4300 channel. Affected file silc/local_command.[ch].
4302 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * Added new local command ME to the client. It is used to send
4305 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4306 some action. Affected file silc/local_command.[ch].
4308 * Changed channel_message and private_message client operations
4309 to deliver the message flags to the application. Added also
4310 the `flags' arguments to the silc_client_send_channel_message
4311 and silc_client_send_private_message functions. Affected file
4314 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4316 * Redefined the Private Message Payload to support private message
4317 keys and to support the new private message flags. Updated
4318 the protocol specs. Flags makes it possible to have for example
4319 CTCP style messages.
4321 * Added new type SilcPrivateMessagePayload and defined an API
4322 for it in the lib/silcclient/silcprivate.[ch].
4324 * Tested private message private keys successfully. Tested the
4325 private message key set, unset and list commands with the new
4328 * Redefined the Channel Message Payload to include the channel
4329 message flags (equal with private message flags) to support
4330 for example CTCP style messages.
4332 * Defined some of the message (for channel and private message)
4333 flags. Updated the protocol specs and added the flags to the
4334 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4336 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4338 * Added SilcKeyAgreementStatus type to the key agreement routines
4339 to indicate the current status and error if one occured.
4340 The status types are defined in the lib/silcclient/silcapi.h.
4342 * Added new local command KEY that is used to set and unset private
4343 keys for channels, set and unset private keys for private messages
4344 with remote clients and to send key agreement requests and
4345 negotiate the key agreement protocol with remote client. The
4346 key agreement is supported only to negotiate private message keys,
4347 it currently cannot be used to negotiate private keys for channels,
4348 as it is not convenient for that purpose.
4350 * Fixed a minor pending callback setting bug in the function
4351 silc_client_get_client_by_id_resolve, now the function works.
4352 Affected file lib/silcclient/idlist.c.
4354 * Added function silc_net_get_local_port to get local bound
4355 port by socket. Added to lib/silcutil/silcnet.[ch].
4357 * Added `sockets' and `sockets_count' fields to the SilcClient
4358 object. They hold the sockets of the listenning sockets in
4359 the client. Listenning sockets may be for example the key
4360 agreement server. Affected file lib/silcclient/client.[ch].
4361 Added functions the silc_client_add_socket and the
4362 silc_client_del_socket. They are exported to the application
4365 * Added ~./silc/clientkeys to support other client's public keys.
4367 * Renamed verify_server_key client operation to verify_public_key
4368 and added one argument to indicate the type of the connection
4369 (server, client etc.).
4371 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4373 * Added silc_server_connection_auth_request to handle the
4374 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4375 silcd/packet_receive.[ch].
4377 * Added silc_server_send_connection_auth_request into the
4378 silcd/packet_send.c to send the connection auth request packet.
4380 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4383 * Fixed the public key authentication in responder side in the
4384 server. The `auth_data' pointer includes the SilcPublicKey
4385 not the path to the public key. Affected file silcd/protocol.c.
4387 * Implemented the public key authentication in the initiator side
4388 in the server. Affected file silcd/protocol.c.
4390 * Removed the [RedirectClient] config section from the server
4391 configuration. Is not needed and I don't want to implement it.
4393 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Cleaned up the CMODE command in the server. It now works
4396 correctly and supports all the modes defined in the protocol.
4397 Affected file is silcd/command.c.
4399 * Added `hmac_name' field to the SilcChannelEntry in the server
4400 to hold the default HMAC of the channel. It can be set when
4401 creating the channel (with JOIN command). Affected files
4404 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4405 type to indicate the change of the current cipher and hmac
4406 on the channel. Client can safely ignore the <cipher> argument
4407 (if it chooses to do so) since the CHANNEL_KEY packet will
4408 force the channel key change anyway. The <hmac> argument is
4409 important since the client is responsible of setting the new
4410 HMAC and the hmac key into use.
4412 * Fixed the CMODE command in the client library as well.
4414 * Tested CMODE command in router environment successfully.
4416 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4418 * Show the version of the remote client (or server) when connecting
4419 to the server. It is logged to the log file. Affected file
4420 is silcd/protocol.c.
4422 * Fixed the KILLED notify handling in the client library. The
4423 client must be removed from all channels when receiving the
4426 Also, do not remove the client entry when giving the KILL
4427 command but when the KILLED notify is received.
4429 * Removed silc_idlist_find_client_by_nickname from the server.
4430 Not needed anymore. Affected files silcd/idlist.[ch].
4432 * Implemented the CHANNEL_CHANGE notify type handling to the
4433 server. Affected file silcd/server.c.
4437 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4439 * Added silc_server_send_notify_invite to send the INVITE
4440 notify between routers.
4442 * Implemented the INVITE command correctly to the server.
4444 * Implemented the INVITE notify type handling in the server.
4446 * Implemented the INVITE command to the client library and on the
4449 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4451 * Added function silc_server_get_client_resolve to find the
4452 client entry by ID from all ID lists and then resolve it
4453 (using WHOIS) if it cannot be found. Affected file is
4456 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4458 * Implemented the BAN command to the client library.
4460 * The JOIN command in the server now checks the invite list
4463 * Changed the silc_command_reply_payload_encode_va and the
4464 silc_command_payload_encode_va to support that if argument is
4465 NULL it ignores and checks the next argument. Affected file
4466 lib/silccore/silccommand.c.
4468 * Added silc_server_send_notify_ban to send the BAN notify
4469 type between routers.
4471 * Chaned the silc_notify_payload_encode to support that if
4472 argument is NULL it ignores and checks the next argument.
4473 Affected file lib/silccore/silcnotify.c.
4475 * Tested ban lists in router environment successfully.
4477 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4479 * Implemented BAN command to the server, in silcd/command.[ch].
4481 * Removed the BAN and INVITE_LIST modes from the CMODE command
4484 * Added function silc_string_match to regex match two strings.
4485 Affected files lib/silcutil/silcutil.[ch].
4487 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4489 * Redefined parts of the SilcChannelEntry in the server to support
4490 the new ban and invite lists.
4492 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Redefined the INVITE command. The same command can be used to
4495 invite individuals to the channel but also to manage the invite
4496 list of the channel (to add to and remove from the invite list).
4497 Updated the protocol specs.
4499 * Added new command SILC_COMMAND_BAN that can be used to manage
4500 the ban list of the channel. Updated the protocol specs.
4502 * Removed the channel modes: the SILC_CMODE_BAN and the
4503 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4504 in the CMODE command. The equivalent features are now available
4505 using INVITE and BAN commands. Updated the protocol specs.
4507 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4508 in the network about change in the current ban list. The notify
4509 type is not used by the client.
4511 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4512 support the invite lists.
4514 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4516 * Added new function silc_string_regexify that converts string
4517 including wildcard characters into regex string that can
4518 be used by the GNU regex library. Added into the file
4519 lib/silcutil/silcutil.[ch].
4521 Added silc_string_regex_combine to combine to regex strings
4522 into one so that they can be used as one regex string by
4523 the GNU regex library. Added into the file
4524 lib/silcutil/silcutil.[ch].
4526 Added silc_string_regex_match to match two strings. It returns
4527 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4529 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Imported GNU regex to the soruce tree into lib/contrib.
4532 Fixed some compiler warning from the regex.c.
4534 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * Fixed MOTD command in the server to work in router environment.
4538 * Fixed the MOTD command in the client library to support
4539 the server argument in the command.
4541 * Added `nickname_len' argument to the silc_idlist_add_client
4542 in the server, as the `nickname' argument may be binary data
4545 * Added silc_idlist_get_channels to return all channels from
4548 * Implemented LIST command to the server. Affected file is
4551 * Implemented the LIST command to the client library and on the
4554 * Added [<user count>] argument to the LIST command reply.
4555 With private channels the user count is not shown.
4557 * Updated TODO and README.
4559 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4561 * The client entry's data.registered must be TRUE even with
4562 global client entry on global client list. The data.registered
4563 is used to check whether the client is anymore in the network,
4564 for example with WHOWAS command so it must be valid.
4566 * Fixed the WHOWAS command in the server. It now actually works
4567 in router environment. Added function into silcd/command_reply.c
4568 silc_server_command_reply_whowas_save.
4570 * Added silc_idlist_purge function to the silcd/idlist.c
4571 to periodically purge the ID Cache.
4573 * Fixed INFO command in the server. It works now in router
4574 environment. Added <server name> argument to the INFO command
4575 reply. Updated the protocol specs.
4577 * Fixed minor bug in silc_idcache_purge to not purge if the
4578 expire value is zero.
4580 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4581 they were buggy because of the WHOWAS information.
4583 * Fixed local command MSG to handle the async resolving of
4584 the remote client properly. It used to fail the first MSG.
4585 Affected file silc/local_command.c.
4587 * Added `data_len' field to SilcIDCache context.
4589 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4591 * Update TODO. Todo in commands in the server.
4593 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4595 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4596 used by routers as broadcast packet to inform other routers
4597 about the changed user mode.
4599 Implemented the notify handling in the server. Affected file is
4600 silcd/packet_receive.c. Added the function
4601 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4603 * Added new generic Channel Payload and deprecated the New Channel
4604 Payload. The New Channel Payload is now the generic Channel
4607 * Added new argument `mode' to the silc_server_send_new_channel
4608 as it is required in the Channel Payload now.
4610 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4611 and created a new and real SilChannelPayload to represent the
4612 new generic Channel Payload. Implemented the encode/decode
4613 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4615 * Added silc_server_get_client_channel_list to return the list
4616 of channels the client has joined for WHOIS command reply.
4617 Affected file silcd/server.[ch].
4619 * Implemented the channel list sending in the WHOIS command reply
4620 in server and in the client.
4622 Implemented the channel list displaying on the user interface
4623 as well. Affected file silc/client_ops.c.
4625 * Added silc_channel_payload_parse_list to parse list of Channel
4626 Payloads. It returns SilcDList list of SilcChannelPayloads.
4627 Client for example can use this function to parse the list of
4628 channels it receives in the WHOIS command reply. The caller
4629 must free the list by calling silc_channel_payload_list_free.
4630 Affected files lib/silccore/silcchannel.[ch].
4632 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4634 * Added one new argument <user mode> to the WHOIS command reply
4635 to return the mode of the user in SILC. Updated the protocol
4638 Implemented it to the server and client.
4640 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * Fixed the mode printing on the user interface on joining.
4643 Affected file silc/client_ops.c.
4645 * Implemented the UMODE command and user modes in general to the
4646 client library and to the user interface.
4648 * Implemented the UMODE command to the server.
4650 * The server now sends UNKNOWN_COMMAND error status if client sends
4651 unknown command. Affected file silcd/command.c.
4653 * All server commands now handle the command identifier the right
4654 way when sending the command reply to the client. The client can
4655 use to identify the command replies with the identifier.
4657 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4659 * Added silc_server_get_client_route to resolve the route to
4660 the client indicated by the client ID. Affected file is
4663 * Added silc_server_relay_packet as general function to relay
4664 packet to arbitrary destination. This deprecates functions
4665 like _send_private_message_key, _relay_notify etc. Affected
4666 file is silcd/packet_send.[ch].
4668 Removed silc_server_send_key_agreement,
4669 silc_server_send_private_message_key and
4670 silc_server_packet_relay_notify functions from the file
4671 silcd/packet_send.[ch].
4675 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4676 server. Affected file silcd/packet_receive.[ch].
4678 * Implemented the KILL command to the client. Implemented the
4679 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4680 Affected files lib/silcclient/command[_reply].c and
4681 lib/silcclient/client_notify.c. Implemented the KILL notify
4682 printing in the user inteface.
4684 * Fixed a lot silc_parse_nick memory leaks from the client
4685 library in the file lib/silcclient/command.c.
4687 * Changed the silc_server_send_notify_on_channels's `sender'
4688 argument from SilcSocketConnection to SilcClientEntry to
4689 check the sender as entry and not as connection object and not
4690 to send to the client provided as argument. The affected file
4691 is silcd/packet_send.[ch].
4693 * The notify packets that are destined directly to the client used
4694 to not to be processed by the server. Now changed that and the
4695 server processes all notify packets. After relaying the packet
4696 to the client the notify packet is processed in the server.
4698 * The silc_server_free_client_data now checks whether there is
4699 pending outgoing traffic for the client and purges the data to
4700 the network before removing the client entry.
4702 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4704 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4705 an client is killed from the SILC Network. Updated the protocol
4708 Added new function silc_server_send_notify_killed to the
4709 silcd/packet_send.[ch].
4711 * Added function silc_server_packet_relay_notify to relay notify
4712 packets that are destined directly to a client. In this case
4713 the server does not process the notify packets but merely relays
4714 it to the client. Affected file silcd/packet_send.[ch].
4716 Added also silc_server_packet_process_relay_notify to check
4717 whereto relay the notify. Affected file is
4718 silcd/packet_receive.[ch].
4720 * Implemented the KILL command to the server.
4724 * Added the backup schema desgined last fall to the protocol
4725 specs for everyone to see. The specification is in the
4726 *-spec-xx.txt draft and the packet type definitions for the
4727 backup routers is in *-pp-xx.txt draft. Thusly, added also
4728 new packet type SILC_PACKET_CELL_ROUTERS.
4730 * A big security problem in the implementation discovered. The
4731 signoff of an client did not cause new channel key generation
4732 which it of course should've done. The channel keys must be
4733 always re-generated when client leaves (or signoffs) the channel.
4734 The silc_server_remove_from_channels funtion now handles
4735 the channel key re-generation.
4737 * Added `sender' argument to the silc_server_send_notify_on_channels
4738 to not to send the client provided as argument. Affected file
4739 silcd/packet_send.[ch].
4741 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4743 * Implemented OPER and SILCOPER commands into the server and
4746 * Added silc_auth_verify and silc_auth_verify_data to verify
4747 the authentication directly from the authentication payload.
4748 It supports verifying both passphrase and public key based
4749 authentication. Affected file lib/silccore/silcauth.[ch].
4751 * Added `hash' field to the SilcIDListData structure. It is the
4752 hash negotiated in the SKE protocol. Affected file is
4755 * Slight redesigning of the SilcAuthPayload handling routines.
4756 Do not send SilcPKCS but SilcPublicKey as argument.
4758 * Implemented the public key authentication support to the
4759 serverconfig. The public key is loaded from the provided path
4760 and saved as authentication data to void * pointer. Thus,
4761 changed the unsigned char *auth_data to void *auth_data;
4763 * Fixed SHUTDOWN command to send the reply before the server
4764 is shutdown. :) Affected file silcd/command.c.
4766 * Fixed fatal bug in CONNECT command. The hostname was invalid
4767 memory and server crashed. Affected file silcd/command.c.
4769 * Fixed fatal bug in CLOSE command. The server_entry became
4770 invalid but was referenced later in the command. Affected file
4773 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4775 * Fixed fatal bug in failure packet handling. Server ignored
4776 the failure and thus crashed when it came.
4780 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4782 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4783 that the command may be executed only once in (about) 2 seconds.
4784 The old SILC_CF_LAG flag is same but allows command bursts up
4785 to five before limiting.
4787 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4788 server code. Various commands now includes the CF_LAG_STRICT
4789 flag to disallow any kind of miss-use of the command.
4791 * Fixed the silc_buffer_unformat to not to allocate any data
4792 if the length of the data is zero. It used to allocate the
4793 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4795 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4797 * Changed the format of AdminConnection configuration section
4798 in the server. Added username of the admin to the format.
4799 Affected files silcd/serverconfig.[ch].
4801 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4802 to return admin configuration data by host, username and/or
4805 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4807 * Implemented WHOWAS command to the server. Added the functions:
4809 silc_server_command_whowas_parse,
4810 silc_server_command_whowas_send_reply,
4811 silc_server_command_whowas_from_client and
4812 silc_server_command_whowas_from_server
4814 * Added <Client ID> argument to the WHOWAS command reply. Updated
4815 the protocol specs accordingly.
4817 * Implemented WHOWAS command and command_reply to the client
4820 Implemented the WHOWAS printing on the user interface.
4822 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4824 * Added new argument to the WHOWAS command reply, the real name.
4825 It is an optional argument. Updated the protocol specs.
4827 * Added SilcIDCacheDestructor callback that is registered when
4828 the SilcIDCache is allocated. The callback is called when
4829 an cache entry in the ID Cache expires, or is purged from the
4830 cache. Added into lib/silccore/idcache.[ch].
4832 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4833 to destruct the client entries when the cache entry expires.
4834 Other ID Cache's in server and in the client library ignores
4837 * If the ID Cache entry's `expire' field is zero then the entry
4838 never expires. Added boolean `expire' argument to the
4839 silc_idcache_add function in the lib/silccore/idcache.[ch].
4840 If it is TRUE the default expiry value is used.
4842 * Added silc_server_free_client_data_timeout that is registered
4843 when client disconnects. By default for 5 minutes we preserve
4844 the client entry for history - for WHOWAS command.
4846 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4848 * Added support to the server to enforce that commands are not
4849 executed more than once in 2 seconds. If server receives
4850 commands from client more frequently, timeout is registered
4851 to process the commands. Affected file silcd/command.c.
4852 Added new function silc_server_command_process_timeout.
4854 * Changed NICK_NOTIFY handling in client library to check that
4855 if the client's nickname was changed, so there is no need to
4856 resolve anything from the server.
4858 * Removed error printing from the WHOIS and IDENTIFY commands.
4859 If error occurs then it is ignored silently in the client library.
4860 The application, however, may map the received error to
4861 human readable error string. The application currently maps
4862 the NO_SUCH_NICKNAME error to string.
4864 * Made the command status message public to the application. Moved
4865 them from lib/silcclient/command_reply.c to
4866 lib/silcclient/command_reply.h. The application can map the
4867 received command status to the string with the
4868 silc_client_command_status_message function.
4870 * Added check to the server to check that client's ID is same
4871 as the Source ID in the packet the client sent. They must
4874 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4876 * Added dist-bzip hook to the Makefile.am to make bzip2
4877 compressed distributions.
4879 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4881 * Server now enforces the maximum length for the nickname and
4882 the channel as protocol specification dictates. 128 bytes for
4883 nickname and 256 bytes for channel name.
4885 * Moved the WHOIS printing to the application. The client libary
4886 does not print out the WHOIS information anymore, the application
4887 must do it. Renamed silc_client_command_reply_whois_print to
4888 the silc_client_command_reply_whois_save.
4890 The client's idle time is also sent to the application now, and
4891 the idle is shown on screen.
4893 * Added silc_client_command_reply_identify_save to save the
4894 received IDENTIFY entries.
4896 * Do not check for channel private keys in message sending and
4897 reception if the channel does not have the PRIVKEY mode set.
4898 Affected file lib/silclient/client_channel.c.
4900 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4903 just surfaced after chaning the JOIN procedure.
4905 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * Added silc_client_get_clients_by_list to get client entries
4908 from Client ID list, that is returned for example by JOIN
4909 and USERS command replies. The application should use this
4910 function for example when JOIN command reply is received to
4911 resolve the clients already on the channel (library does not
4912 do that anymore as USERS command reply is not used in the JOIN
4913 procedure anymore). Affected files lib/silcclient/silcapi.h and
4914 lib/silcclient/idlist.c.
4916 * JOIN command reply and USERS command reply returns now SilcBuffer
4917 pointers instead of unsigned char pointers when returning
4918 the client list and mode list.
4920 * Added <Client ID> argument to the JOIN command reply, mainly
4921 for the server to identify for which client the command was
4922 originally sent. Updated protocol specs accordingly.
4924 * Added SilcDlist private_key pointer to the SilcChannelEntry
4925 in the client to support the channel private keys. Affected
4926 file is lib/silcclient/idlist.h.
4928 * Added SilcChannelPrivateKey argument to the function
4929 silc_client_send_channel_message so that application can choose
4930 to use specific private ke if it wants to. If it is not provided,
4931 the normal channel key is used, unless private keys are set.
4932 In this case the first (key that was added first) is used
4933 as the encryption key.
4935 * Implemented the support for channel private key handling.
4936 Implemented the following functions:
4938 silc_client_add_channel_private_key,
4939 silc_client_del_channel_private_keys,
4940 silc_client_del_channel_private_key,
4941 silc_client_list_channel_private_keys and
4942 silc_client_free_channel_private_keys
4944 Affected file lib/silcclient/client_channel.c.
4946 * Added the support for the private keys in the channel message
4947 sending and encryption and in the message reception and
4948 decryption. Affected funtions are
4949 silc_client_send_channel_message and silc_client_channel_message.
4951 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4953 * Added SKE's key verify callback to the client library's
4954 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4956 * Removed the statement that server (or router) must send USERS
4957 command reply when joining to the channel so that the client
4958 knows who are on the channel. Instead, the client list and
4959 client's mode list is now sent in the JOIN command reply to the
4960 client who joined channel. This is better solution.
4962 * Added function silc_server_get_users_on_channel and function
4963 silc_server_save_users_on_channel to the silcd/server.[ch].
4965 * Removed function silc_server_command_send_users from the
4968 * Do not show topic on the client library anymore. The topic is
4969 sent in the command reply notify to the application and the
4970 application must show the topic now.
4972 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4974 * Added client searching by nickname hash into the IDENTIFY and
4975 WHOIS commands in the server as they were clearly missing from
4976 them. Affected file is silcd/command.c.
4978 * Fixed a bug in private message receiving in the client library.
4979 The remote ID was freed and it wasn't supposed, now it is
4982 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4984 * Minor fix to the channel payload; allocate the data area, as it
4985 needs to be of specific length.
4987 * If the key agreement port is zero then the operating
4988 system will define the bound port. Affected files are
4989 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4991 * Added new function silc_channel_payload_decrypt into the file
4992 lib/silccore/silcchannel.[ch].
4994 * Moved the channel message etc, check from silc_packet_decrypt
4995 to applications. The library calls now a generic
4996 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4997 when the packet is either normal or special. This was done to
4998 allow more wide range of checking that was not allowed when
4999 the code was in library. Now applications can do virtually any
5000 checks to the packet and return to the library the decision how
5001 the packet should be processed. Affected files are
5002 lib/silccore/silcpacket.[ch].
5004 Added silc_server_packet_decrypt_check to the server and
5005 silc_client_packet_decrypt_check to the client library.
5007 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5008 to send with specified source and destination information.
5010 * Channel message delivery between routers was broken after the
5011 channel key distribution was fixed earlier. The channel key
5012 was used be to distributed to other routers as well which is not
5013 allowed by the protocol. Now this is fixed and channel keys
5014 really are cell specific and the channel message delivery between
5015 routers comply with the protocol specification.
5017 * Fixed various commands in server to check also the global list
5018 for the channel entry and not just the local list. The affected
5019 file silcd/command.c.
5021 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5023 * Added assert()s to buffer formatting and unformatting routines
5024 to assert (if --enable-debug) when error occurs. Affected
5025 file: lib/silcutil/silcbuffmt.c.
5027 * Changed to auto-reconnect to check whether the remote host is
5028 router and register the re-connect timeout if it is. It used
5029 to check that whether we are normal server, but router must do
5030 auto-reconnect with another router as well. Affected file
5033 * Removed the [<key len>] option from CMODE command as the cipher
5034 name decides the key length, nowadays. See the defined ciphers
5035 from the protocol specification.
5037 * Added [<hmac>] option to the CMODE command to define the HMAC
5038 for the channel. Added SILC_CMODE_HMAC channel mode.
5040 * Added [<hmac>] option for the JOIN command so that user can
5041 select which HMAC is used to compute the MACs of the channel
5044 * Added Hmac field to the Channel Message Payload. The integrity
5045 of plaintext channel messages are now protected by computing
5046 MAC of the message and attaching the MAC to the payload. The
5047 MAC is encrypted. Now, it is clear that this causes some
5048 overhead to the size of the packet but rationale for this is that
5049 now the receiver can verify whether the channel message decrypted
5050 correctly and also when private keys are set for the channel the
5051 receiver can decrypt the packet with several keys and check from
5052 the MAC which key decrypted the message correctly.
5054 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5055 lib/silccrypt/silccipher.[ch].
5057 * Added silc_hash_len to return the digest length into the
5058 lib/silcrypt/silchash.[ch].
5060 * Rewrote parts of Silc Channel Payload interface in the
5061 lib/silccore/silcchannel.[ch]. The encode function now also
5062 encrypts the packet and parse function decrypts it.
5064 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5066 * Fixed a minor formatting bug in the SKE's key material processing.
5067 It actually might have processed the keys wrong way resulting
5070 * Redefined the mandatory HMAC algorithms and added new algorithms.
5071 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5072 and hmac-md5 truncated to 96 bits. The mandatory is now
5073 hmac-sha1-96. Rest are optional (including the one that used
5074 to be mandatory). Rationale for this is that the truncated HMAC
5075 length is sufficient from security point of view and can actually
5076 make the attack against the HMAC harder. Also, the truncated
5077 HMAC causes less overhead to the packets. See the RFC2104 for
5080 * Added new [hmac] configuration section. The SKE used to use
5081 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5082 is of course wrong. The official names that must be proposed in
5083 the SKE are the ones defined in the protocol specification
5084 (hmac-sha1-96 for example). The user can configure any hmac
5085 using any hash function configured in the [hash] section. At
5086 least, the mandatory must be configured.
5088 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5090 * Added HMAC list to the SKE proposal list. It has now both
5091 hash algorithm list and HMAC list. This makes the protocol
5092 incompatible with previous versions. The SKE now seems to work
5093 the way it is supposed to work, for the first time actually.
5095 * Defined plain Hash algorithms to the protocol specification.
5098 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5100 * Implemented support for key agreement packets into the server.
5101 Added functions silc_server_key_agreement and
5102 silc_server_send_key_agreement. Other than these functions,
5103 server has nothing to do with this packet.
5105 * Added support for private message key packets into the server.
5106 Added functions silc_server_private_message_key and
5107 silc_server_send_private_message_key.
5111 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5112 called in the protocol's final callback instead in the END
5113 protocol state. This makes a little more sense and in the same
5114 time in client we can use the same protocol routines for normal
5115 key exchange and to key agreement packet handling as well.
5117 * Added to both client's and server's KE protocol context the
5118 SilcSKEKeyMaterial pointer to save the key material. We will
5119 bring the key material to the protocol's final callback by doing
5120 this. The final callback must free the key material.
5122 * Added SKE's packet_send callback into client's KE protocol
5123 context so that the caller can choose what packet sending function
5124 is used. This way we can use different packet sending when
5125 doing normal SKE when doing key agreement packet handling (in
5126 the key agreement packet handling we do not want to encrypt
5129 * Implemented the responder side of the key agreement routines
5130 in the client. The client can now bind to specified port and
5131 accept incoming key negotiation. The key material is passed
5132 to the application after the protocol is over.
5134 * Implemented the processing of incoming Key Agreement packet
5135 in the client. Added function silc_client_key_agreement to
5138 * Implemented the intiator side of the key agreement routines
5139 in the client. The client can now initiate key agreement with
5140 another remote client. The key material is passed to the
5141 application after the protocol is over.
5143 * Created client_keyagr.c to include all the key agreement
5146 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5147 SILC_TASK_CALLBACK except that it is not static.
5149 * Created client_notify.c and moved the Notify packet handling
5150 from the client.[ch] into that file.
5152 * Created client_prvmsg.c and moved all private message and
5153 private message key routines from the client.[ch] into that file.
5155 * Create client_channel.c and moved all channel message and
5156 channel private key routines from the client.[ch] into that file.
5158 * Changed silc_client_get_client_by_id_resolve to resolve with
5159 WHOIS command instead of IDENTIFY command, in the file
5160 lib/silclient/idlist.c.
5162 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5164 * Implemented the SKE's responder side to the Client library.
5166 * When FAILURE is received to the protocol do not trust it
5167 blindly. Register a timeout to wait whether the remote closes
5168 the connection as it should do it, only after that process the
5169 actual failure. This was changed to both client and server.
5171 * Added client_internal.h to include some of the structures
5172 there instead of client.h in lib/silcclient/.
5174 * Added function silc_task_unregister_by_callback to unregister
5175 timeouts by the callback function.
5177 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5179 * Some "Incomplete WHOIS info" errors has been appearing on the
5180 log files. Took away the entry->userinfo check from WHOIS
5181 reply sending. The entry->userinfo is now " " if client did not
5182 provide one. I thought this was fixed earlier but something
5183 is wrong still. Let's see if the error still appears.
5185 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5187 * Fixed a minor bug in the login when the channel key is
5188 re-generated in the server. It used to generate the key in
5189 wrong order and thus caused problems in the channel traffic.
5191 * Fixed a minor bug in channel key distsribution after
5192 KICK command. The key was not sent to the router even though
5195 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5197 * Added silc_ske_process_key_material_data as generic routine
5198 to process any key material as the SILC protocol dictates. The
5199 function is used by the actual SKE library but can be used by
5200 applications as well. This relates to the private message keys
5201 and the channel private keys since they must be processed the
5202 same way the normal SILC session keys. The protocol dictates
5203 this. Affected files: lib/silcske/silcske.[ch].
5205 Added also silc_ske_free_key_material to free the
5206 SilcSKEKeyMaterial structure.
5208 * Defined silc_cipher_set_key function to set the key for
5209 cipher without using the object's method function. The affected
5210 files: lib/silccrypt/silccipher.[ch].
5212 * Implemented silc silc_client_add_private_message_key,
5213 silc_client_add_private_message_key_ske,
5214 silc_client_del_private_message_key,
5215 silc_client_list_private_message_keys and
5216 silc_client_free_private_message_keys functions in the
5219 Added functions silc_client_send_private_message_key to send
5220 the Private Message Key payload and silc_client_private_message_key
5221 to handle incoming Private Message Key payload.
5223 * Added Cipher field to the Private Message Key payload to set
5224 the cipher to be used. If ignored, the default cipher defined
5225 in the SILC protocol (aes-256-cbc) is used.
5227 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5229 * Removed lib/silcclient/ops.h file.
5231 Redefined parts of the SILC Client Library API. Created new
5232 file silcapi.h that deprecates the ops.h file and defines the
5233 published Client Library API. Defined also private message key
5234 API and channel private key API into the file.
5236 This is the file that the application must include from the
5237 SILC Client Library. Other files need not be included by
5238 the application anymore.
5240 * Added new key_agreement client operation callback and also
5241 defined the Key Agreement library API for the application.
5243 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5246 is used by clients to request key negotiation between another
5247 client in the SILC network. If the negotiation is started it
5248 is performed using the SKE protocol. The result of the
5249 negotiation, the secret key material, can be used for example
5250 as private message key.
5252 Implemented the Key Agreement payload into the files
5253 lib/silccore/silauth.[ch].
5255 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5257 * Redefined ciphers for the SILC protocol. Added some new ciphers
5258 and defined the key lengths for the algorithms. Changed the
5259 code accordingly. The default key length is now 256 bits.
5261 * Fixed SKE key distribution function silc_ske_process_key_material
5262 when the key length is more than 128 bits. The default key
5263 length in SILC is now 256 bits.
5265 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5266 to indicate unsupported algorithm.
5268 * Renamed rijndael.c to aes.c and all functions as well.
5270 * Fixed a long standing channel key setting bug in client library.
5271 Weird that it has never surfaced before.
5273 * Fixed bug in channel deletion. If the entire channel is removed
5274 then it must also delete the references of the channel entry
5275 from the client's channel list as the client's channel entry and
5276 the channel's client entry share same memory.
5278 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5280 * Implemented CONNECT and SHUTDOWN commands in the client.
5282 * Implemented CLOSE command to the client.
5284 * Added the function silc_idlist_find_server_by_name into the
5285 files silcd/idlist.[ch].
5287 Added the function silc_idlist_find_server_by_conn into the
5288 files silcd/idlist.[ch].
5290 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5292 * DIE command was renamed to SHUTDOWN. Updated the both code
5295 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5296 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5298 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5301 * Added function silc_server_create_connection function to create
5302 connection to remote router. My server implementation actually
5303 does not allow router to connect to normal server (it expects
5304 that normal server always initiates the connection to the router)
5305 so the CONNECT command is only good for connecting to another
5308 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5310 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5311 or some other client was kicked from the channel.
5313 Implemented the handling of the notify type to both client
5316 Implemented silc_server_send_notify_kicked to send the KICKED
5317 notify. It is used to send it to the server's primary router.
5319 * Implemented the KICK command into server and client.
5321 * Added `query' argument to the silc_idlist_get_client function
5322 to indicate whether to query the client from server or not if
5325 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5326 to indicate that the client is not channel founder.
5330 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5332 * Removed the rng context from SilcPacketContext structure and
5333 changed that the packet routine uses the Global RNG API.
5335 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Added support for quit message that client can "leave" on the
5338 channel when it quits the SILC. It is ditributed inside the
5339 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5341 Added silc_server_free_client_data that will take the
5342 signoff message as argument.
5344 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5346 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5348 * Updated parts of the protocol specification to keep it up
5351 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5353 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5354 payloads in one packet.
5356 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5357 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5358 use now the new List flag.
5360 * Also deprecated the following packet types: REPLACE_ID,
5361 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5363 * Added list support for Notify packet in server.
5365 * Added silc_server_send_notify_channel_change to send the
5366 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5367 the silc_server_send_replace_id.
5369 * Added silc_server_send_notify_nick_change to send the
5370 NICK_CHANGE notify type. Deprecates the function
5371 silc_server_send_replace_id.
5373 * Added silc_server_send_notify_join to send the JOIN notify type.
5374 Deprecates the function silc_server_send_new_channel_user.
5376 * Added silc_server_send_notify_leave to send LEAVE notify type.
5377 Deprecates the function silc_server_send_remove_channel_user.
5379 * Added silc_server_send_notify_cmode and
5380 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5381 types. Deprecates the silc_server_send_set_mode function.
5383 * Added SERVER_SIGNOFF notify type to indicate that server has
5384 quit. This means that all clients on the channel from that
5385 server will drop. This can be also used when netsplit happens.
5387 Deprecated REMOVE_ID packet type since it is not needed anymore
5390 Added silc_server_send_notify_server_signoff to send the
5391 SERVER_SIGNOFF notify type. Deprecates the function
5392 silc_server_send_remove_id.
5394 Added also silc_server_send_notify_signoff to send the
5395 SIGNOFF notify type.
5397 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5398 SILC protocol from this day on. Changed the protocol
5399 specification as well.
5401 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5402 notify type. It is used between routers to notify about
5403 topic changes on a channel.
5405 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5408 * Partly updated the protocol specification to comply with the
5409 changes now made. It is still though a bit outdated.
5411 * The JOIN notify type now takes one extra argument <Channel ID>.
5412 The packet used to be destined to the channel but now the
5413 JOIN type may be sent as list thus it is impossible to
5414 destine it to any specific channel. By adding this argument
5415 it is again possible.
5417 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5419 * Added CREDITS file. The CHANGES and CREDITS file will appear
5420 in the distribution as well.
5422 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5425 types in the server's silcd/packet_receive.c.
5427 * Implemented CMODE and CUMODE to work in router environment.
5429 * Fixed minor encoding and decoding buglet from the
5430 lib/silccore/silcmode.c.
5432 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5435 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5437 * Changed all SilcConfigServer* and silc_config_server* to
5438 SilcServerConfig* and silc_server_config*, respectively.
5441 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5443 * Associated the ID (client or server ID) to the Authentication
5444 Payload to avoid any possibility of forging. Updated the
5445 protocol specification and the code accordingly.
5447 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5449 * The RSA key length is now save to the RsaKey context in the
5450 key generation process in lib/silccrypt/rsa.c. The key length
5451 is now used to figure out the maximum size of the block allowed
5452 to be encrypted/signed.
5454 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5455 is equivalent to the silc_mp_mp2bin but does not allocate any
5458 * Changed silc_mp_mp2bin API to take length argument. If it is
5459 non-zero then the buffer is allocated that large. If zero, then
5460 the size is approximated using silc_mp_sizeinbase, which however
5463 * Created Global RNG API which is global RNG that application can
5464 initialize. After initializing, any routine anywhere in the
5465 code (including library) can use RNG without allocating a new
5466 RNG object. This was done to allow this sort of use of the
5467 RNG in code that has no chance to allocate RNG object. All
5468 applications currently allocate this and many routines in the
5469 library use this. Affected file lib/silccrypt/silcrng.[ch].
5471 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5472 it to use the Global RNG API.
5474 * Defined Authentication Payload into protocol specification that
5475 is used during SILC session to authenticate entities. It is
5476 used for example by client to authenticate itself to the server
5477 to obtain server operator privileges.
5479 Implemented this payload into the lib/silccore/silcauth.[ch].
5480 Implemented also routines for public key based authentication
5481 as the new protocol specification dictates.
5483 Moved definitions of different authentication methods from
5484 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5486 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5487 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5488 silc_pkcs_verify_with_hash functions into the file
5489 lib/silccrypt/silcpkcs.[ch].
5491 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5493 * The client entry's userinfo pointer must be always valid.
5494 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5495 will fail since it requires the userinfo. Now, the userinfo
5496 is allocated as "" if actual userinfo does not exist. Actually,
5497 it must exist and it is totally Ok to drop client connections
5498 that does not announce the userinfo. However, we will make
5499 this workaround for now.
5501 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5502 to return the remote port by socket.
5504 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5506 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5507 SILC_SERVER_PENDING_EXEC and added an new macro
5508 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5509 data or when error occurs while processing the pending command.
5511 Added new argument `destructor' into silc_server_command_pending
5512 and to the SilcServerCommandPending object. This destructor is
5513 now called after calling the pending callback or if error occurs
5514 immediately. If error occurs the actual pending callback won't
5515 be called at all - only the destructor. The destructor may be
5516 NULL if destructor is not needed.
5518 All this applies for client library code as well. Similar
5519 changes were made there as well for the pending commands.
5521 In the client, the application must now allocate the
5522 SilcClientCommandContext with the silc_client_command_alloc
5525 * Added reference counter to the SilcServerCommandContext. Added
5526 function silc_server_command_alloc and silc_server_command_dup
5529 Same type of functions added to the client library for the same
5532 * Removed the cmd_ident from IDListData away since it is now
5533 global for all connections. It is the command identifier used
5534 in command sending and with pending commands. The affected file
5537 * Added reference counter to the SilcSocketConnection objecet to
5538 indicate the usage count of the object. The object won't be
5539 freed untill the reference counter hits zero. Currently only
5540 server uses this, and client ignores it. The client must be
5541 set to use this too later. The affected files are
5542 lib/silccore/silcsockconn.[ch]. Added also the function
5543 silc_socket_dup to increase the reference counter.
5545 This was mainly added because it is possible that the socket
5546 is removed underneath of pending command or other async
5547 operation. Now it won't be free'd and proper DISCONNECTING
5548 flags, etc. can be set to avoid sending data to connection that
5549 is not valid anymore.
5551 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5552 the connection. After that it sets SILC_SET_DISCONNECTED.
5553 It is, however, possible that the socket data is not still freed.
5554 The silc_server_packet_process now checks that data is not
5555 read or written to connection that is DISCONNECTED. The socket
5556 get's freed when the reference counter hits zero.
5558 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5560 * Changed the client operation API: channel_message operation's
5561 `sender' is now the client entry of the sender, not the nickname
5562 and the `channel' is the channel entry, not the channel name.
5564 In the private_message operation the `sender' is now also the
5565 client entry of the sender not the nickname.
5567 Affected file is lib/silcclient/ops.h and all applications
5568 using the client operations.
5570 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5572 * Moved the calling of ops->connect() from connect_to_server_final
5573 into receive_new_id functin since that is the point when the
5574 client is actually allowed to send traffic to network. The
5575 affected file is lib/silcclient/client.c.
5577 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5579 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5580 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5581 (if needs broadcasting) instead of broadcasting the packets one
5582 by one which would make a burst in the network traffic.
5584 * Added `broadcast' argument to the functions in silcd/server.[ch]
5585 silc_server_create_new_channel[_with_id] to indicate whether
5586 to send New Channel packet to primary router.
5588 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5590 * Added new function into the silcd/server.[ch] files:
5591 silc_server_create_new_channel_with_id to create new channel with
5592 already existing Channel ID.
5594 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5595 lib/silccore/silcpacket.h. This packet is used t send list of
5596 Set Mode payloads inside one packet. Server uses this to set
5597 the modes for the channels and clients on those channels, that it
5598 announced to the router when it connected to it. The protocol
5599 specification has been updated accordingly.
5601 * The silc_server_new_channel did not handle the packet coming
5602 from normal server as it normally does not send that. However,
5603 when it announces its channels it does send it. Implemented
5604 the support for that.
5606 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5607 into the file lib/silccore/id.h.
5609 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5611 * Fixed memory leaks in the functions silc_idlist_del_client,
5612 silc_idlist_del_channel and silc_idlist_del_server in the file
5613 silcd/idlist.c. All of those leaked like a sieve.
5615 * Fixed some small memory leaks in the client's function
5616 silc_client_notify_by_server.
5618 * Added functions into silcd/server.c: silc_server_announce_clients,
5619 silc_server_announce_channels and silc_server_announce_server.
5620 These functions are used by normal and router server to announce
5621 to its primary router about clients, channels and servers (when
5622 router) that we own. This is done after we've connected to the
5625 These functions effectively implements the following packet types:
5626 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5627 and SILC_PACKET_NEW_ID_LIST.
5629 * Added new functions into the silcd/packet_receive.[ch]:
5630 silc_server_new_id_list, silc_server_new_channel_list and
5631 silc_server_new_channel_user_list to handle the incoming
5632 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5634 * Added support of changing Channel ID in the function
5635 silc_server_replace_id. If the server that announces a channel
5636 to the router already exists in the router (with same name but
5637 with different Channel ID), router is responsible to send
5638 Replace ID packet to the server and force the server to change
5639 the Channel ID to the one router has.
5641 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5642 client that the Channel ID has been changed by the router. The
5643 normal server sends this to the client. Client must start using
5644 the new Channel ID as the channel's ID.
5646 Implemented handling of this new type into lib/silcclient/client.c
5647 into the function silc_client_notify_by_server.
5649 * Added new function silc_idlist_replace_channel_id into the files
5650 silcd/idlist.[ch] to replace the Channel ID.
5652 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5654 * Call silc_server_command_identify_check always when processing
5655 the IDENTIFY command in silcd/command.c
5657 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5659 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5660 send keepalive packets. The packet can be sent by clients,
5661 servers and routers.
5663 Added function silc_socket_set_heartbeat into the file
5664 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5665 If not set, the heartbeat is not performed. The actual
5666 heartbeat is implemented in the low level socket connection
5667 library. However, application is responsible of actually
5670 Added silc_server_send_heartbeat to send the actual heartbeat
5671 packet into silcd/packet_send.[ch]. Server now performs
5672 keepalive with all connections.
5674 * Added silc_task_get_first function into lib/silcutil/silctask.c
5675 to return the timeout task with shortest timeout. There was a bug
5676 in task unregistration that caused problems. TODO has been
5677 updated to include that task system must be rewritten.
5679 * The client library will now resolve the client information when
5680 receiving JOIN notify from server for client that we know but
5681 have incomplete information.
5683 * Rewrote parts of silc_server_remove_from_channels and
5684 silc_server_remove_from_one_channel as they did not remove the
5685 channel in some circumstances even though they should've.
5687 * Encryption problem encountered in server:
5689 The LEAVE command used to send the Channel Key packet to the
5690 router immediately after generating it. However, the code
5691 had earlier sent Remove Channel user packet but not immediately,
5692 ie. it was put to queue. The order of packets in the router
5693 was that Channel Key packet was first and Remove Channel User
5694 packet was second, even though they were encrypted in the
5695 reverse order. For this reason, MAC check failed. Now, this
5696 is fixed by not sending the Channel Key packet immediately but
5697 putting it to queue. However, this is more fundamental problem:
5698 packets that are in queue should actually not be encrypted
5699 because packets that are sent immediately gets encrypted
5700 actually with wrong IV (and thus MAC check fails). So, packets
5701 that are in queue should be encrypted when they are sent to
5702 the wire and not when they put to the queue.
5704 However, the problem is that the current system has not been
5705 designed to work that way. Instead, the packet is encrypted
5706 as soon as possible and left to the queue. The queue is then
5707 just purged into wire. There won't be any fixes for this
5708 any time soon. So, the current semantic for packet sending
5711 o If you send packet to remote host and do not force the send
5712 (the packet will be in queue) then all subsequent packets to the
5713 same remote host must also be put to the queue. Only after the
5714 queue has been purged is it safe again to force the packet
5717 o If you send all packets immediately then it safe to send
5718 any of subsequent packets through the queue, however, after
5719 the first packet is put to queue then any subsequent packets
5720 must also be put to the queue.
5722 Follow these rules and everything works fine.
5724 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5726 * Added new function silc_server_remove_clients_by_server to
5727 remove all client entries from ID list when the server connection
5728 is lost. In this case it is also important to invalidate all
5729 client entires as they hold the invalid server entry. This
5730 fixes fatal bug when server has lost connection and will reconnect
5733 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5735 * Made some sanity checks to silc_server_daemonise like to check
5736 whether the requested user and group actually exists.
5738 * Added sanity check to SKE's silc_ske_responder_finish to check
5739 that the public and private key actually is valid.
5741 * Invalidate the client's nickname when receiving Replace ID
5742 packet and the Client ID is being replaced. This means that the
5743 server will query the nickname if someone needs it (client)
5746 * Sort the ID Cache in client library when the ID Cache data
5747 has changed (needs sorting).
5749 * Do not allow for SILC client to create several connections to
5750 several servers. The client does not support windows right now
5751 and generating multiple connections causes weird behaviour.
5753 Irssi-silc client does support windows and can handle several
5754 connections without problems, see: www.irssi.org and SILC plugin.
5756 * Fixed some places where client was added to the IDList. The
5757 rule of thumb is following (in order to get everything right):
5758 If the client is directly connected local client then the
5759 `connection' argument must be set and `router' argument must be
5760 NULL to silc_idlist_add_client function. If the client is not
5761 directly connected client then the `router' argument must
5762 bet set and the `connection' argument must be NULL to the
5763 silc_idlist_add_client function.
5765 * The funtion silc_server_packet_send_local_channel actually did
5766 not check whether the client was locally connected or not. It
5767 does that now. Fixed a bug related to LEAVE command.
5769 * Fixed Remove Channel User payload parsing bug in server's
5770 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5772 * The server's silc_server_save_channel_key now checks also the
5773 global ID list for the channel as it might not be in the local
5774 list. Fixed a bug related to LEAVE command.
5776 * Is this the end of the [<unknown>] buglet that has been lurking
5777 around for a long time? A little for loop fix in server's
5778 silc_server_command_whois_parse that is used by both IDENTIFY
5779 and WHOIS command. At least, this was a clear bug and a cause
5780 of one type of [<unknown>] buglet.
5782 * WHOIS and IDENTIFY commands call the function
5783 silc_server_command_[whois/identify]_check function even if
5784 we are not router server.
5786 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5788 * Added --with-gmp configuration option. If set the GMP
5789 is always compiled in the SILC source tree. If not set then
5790 it is checked whether the system has the GMP3 installed. If
5791 it has then the GMP won't be compiled (the system's headers
5792 and library is used), if it doesn't have it then the GMP is
5793 compiled in the SILC source tree.
5795 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Changed RSA private exponent generation to what PKCS #1
5798 suggests. We try to find the smallest possible d by doing
5799 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5800 not security fix but optimization.
5802 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5804 * Added new config entry [Identity] to fork the server and run
5805 it as specific user and group. A patch from Bostik.
5807 * Imported Dotconf configuration library into lib/dotconf.
5808 This will be used to create the SILC configuration files later.
5809 It will appear in the distsribution after this commit.
5811 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5813 * A big code auditing weekend happening. Auditing code for
5814 obvious mistakes, bugs and errors. Also, removing any code
5817 Removed files for being obsolete:
5819 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5820 inline in the file lib/silcutil/silcbuffer.h)
5822 o lib/silcutil/silcbufutil.c (the header has inline versions)
5824 Changed code to fix possible error conditions:
5826 o The buffer formatting routines now check that the destination
5827 buffer really has enough space to add the data. This applies for
5828 both buffer formatting and unformatting
5829 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5830 unformatting was changed to accomodate following rules:
5831 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5832 sent to the function while XXX_*STRING will not allocate or copy
5833 the data into the buffer. Instead it sets the pointer from the
5834 buffer into the pointer sent as argument (XXX_*STRING used to
5835 require that the pointer must be allocated already). This change
5836 makes this whole thing a bit more consistent and more optimized
5837 (note that the data returned in the unformatting with XXX_*STRING
5838 must not be freed now). The routines return now -1 on error.
5840 o Tried to find all code that use buffer_format and buffer_unformat
5841 and added return value checking to prevent formatting and
5842 especially unformatting errors and possible subsequent fatal
5845 o Changed ske->x and ske->KEY to mallocated pointers in
5846 lib/silcske/silcske.h. Fixed possible data and memory leak.
5848 o Added return value checking to all *_parse* functions. Fixed
5849 many memory leaks as well.
5851 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5852 so that buffer overflows would not happen. All code now also
5853 checks the return value as it can fail.
5855 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5857 * Added reconnection support to server if the normal server looses
5858 its connection to the router (for example if router is rebooted).
5859 The server performs normal reconnection strategy implemented
5860 to the server. Affected file silcd/server.c.
5862 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5864 * Added new packet type SILC_PACKET_SET_MODE that is used to
5865 distribute the information about changed modes (for clients,
5866 channels and clients channel modes) to all routers in the
5867 network. Updated the protocol specification accordingly.
5869 Added functions into silcd/packet_send.c and
5870 silcd/packet_receive.c: silc_server_send_set_mode,
5871 silc_server_set_mode.
5873 Added new files silcmode.[ch] into lib/silccore that implements
5874 the encoding and decoding of Set Mode Payload. Added new type
5875 SilcSetModePayload. Moved the definitions of different modes
5876 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5878 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5880 * Oops, a little mistake in server's connection authentication
5881 protocol. The protocol is not ended with FAILURE but with
5882 SUCCESS if the authentication is Ok. :) Affected file is
5885 * Implemented NICK_CHANGE notify handling in server in the file
5886 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5887 the local clients on the channel. After the changing nickname
5888 in router environment snhould work and the [<unknown>] nickname
5889 should appear no more.
5891 The silc_server_replace_id function that receives the Replace ID
5892 payload now sends the NICK_CHANGE notify type also in the file
5893 silcd/packet_receive.c
5895 * Changed WHOIS and IDENTIFY command to support the maximum amount
5896 of arguments defined in protocol specs (3328 arguments). This
5897 fixed a bug that caused problems when there were more than three
5900 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5902 * Added extra parameter, command identifier, to the
5903 silc_client_send_command so that explicit command identifier
5906 Changed that ID list routines uses specific command identifier
5907 when sending WHOIS/IDENTIFY requests to the server so that they
5908 can be identified when the reply comes back.
5910 Affected files lib/silcclient/command.[ch],
5911 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5913 * Added `sender' argument to silc_server_packet_send_to_channel
5914 to indicaet the sender who originally sent the packet to us
5915 that we are now re-sending. Ignored if NULL. Affected file
5916 silcd/packet_send.[ch].
5918 * Added some server statistics support in silcd/server_internal.h
5919 SilcServerStatistics structure and around the server code. Also
5920 send some nice statistics information when client is connecting
5923 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5925 * Fixed channel ID decoding in server's JOIN command reply in
5926 silcd/command_reply.c
5928 * Fixed braodcasting of replace ID payload to not to send it if
5929 we are standalone server in silcd/packet_receive.c.
5931 * Fixed all channel message sending routines to not to send
5932 packets to clients that has router set, since they are routed
5933 separately in the same function earlier. Affects file
5934 silcd/packet_send.c and all channel packet sending functions.
5936 * In USERS reply, res_argv[i] are not allocated, the table
5937 is allocated. Thus changed that free the table, not its
5940 * In server's whois_check and identify_check if the client is
5941 locally connected do not send any WHOIS commands - they are not
5944 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5946 * Fixed some minor bugs in client when sending WHOIS command. The
5947 arguments was in wrong order.
5949 * Removed statis function add_to_channel from server in
5950 silcd/command.c that was previously used with the joining but
5953 * Tested USERS command in router environment successfully with two
5954 routers, two servers and two clients.
5956 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5958 * Reorganized the USERS command and command reply in client library
5959 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5960 When the command is given by user we register a pending command
5961 callback that will reprocess the command after the reply has been
5962 received from the server. When reprocessing the packet we then
5963 display the information. Thus, the USERS information is displayed
5964 now in the command callback instead of in the command reply
5965 callback. The processing of the command is same as previously
5966 when server has sent the command reply in the JOINing process.
5968 * Added to USERS command in silcd/command_reply.c to join the client,
5969 we didn't use to know about, to the channel after we've created
5970 a client entry for it. Also, for clienet we did know already still
5971 check whether it is on the channel or not and add it if not.
5973 * Removed silc_server_command_join_notify as the function and its
5976 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5978 * Changed the client's pending command handling to the same as the
5979 server's pending command handling. It is also now possible to
5980 execute command reply functions from other command reply
5981 function as the function callbacks for commands and command
5982 replies are one and same. The pending commands are not static
5983 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5984 in client connection context. Thus, pending commands are server
5985 connection specific as it is convenient.
5987 Changed the function silc_client_command_pending and
5988 silc_client_command_pending_del and added new function
5989 silc_client_command_pending_check. Removed the
5990 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5993 * Added cmd_ident, current command identifier, to the client
5994 connection context in lib/silcclient/client.h to keep track on
5995 command identifiers used in command sending. Client's command reply
5996 function handling now supports the mandatory command identifiers.
5998 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5999 funtions in client to fully support pending command callbacks.
6001 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6002 as one of the arguments to the application in the command reply
6005 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6006 before first releasing SILC but came back. Now it is removed again
6007 and should come back nomore. The FORWARDED flag was used only
6008 by the JOINing procedure by forwarding the command packet to router.
6009 Now, the JOINing procedure has been changed to more generic (due
6010 to various router environment issues) and FORWARDED is not needed
6011 anymore for anything. The protocol specification is yet to be
6014 Now, removed silc_server_packet_forward from server and the flag
6015 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6017 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6019 * Renamed NAMES command to USERS command. The NAMES was named that
6020 due to historical reasons. Now it is renamed. Also, rewrote
6021 parts of the USERS command. The nickname list is not sent anymore
6022 by the server. Only Client ID and mode lists are sent in the USERS
6023 command. Changed this also to the protocol specification.
6025 The client now resolves the names and stuff after it receives
6026 the USERS list from the server when joining to the channel.
6028 * WHOIS and IDENTIFY commands has been changed to support multiple
6029 Client ID's per command. One can now search for multiple users
6030 in the network by sending only one WHOIS or IDENTIFY command.
6031 Changed the code and the protocol specifications.
6033 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6034 uses silc_server_command_whois_parse to parse the request. */
6036 * If normal server, do not parse the WHOIS and IDENTIFY requests
6037 before sending it to the router. Saves some time.
6039 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6041 * Fixed JOIN command on client library. Wrong number of arguments
6042 used to crash the client.
6044 * Added silc_server_channel_has_global function to check whether
6045 channel has global users or not.
6047 * Added silc_server_channel_has_local function to check whether channel
6048 has locally connected clients on the channel.
6050 * The silc_server_remove_from_one_channel now checks whether the
6051 channel has global users or not after given client was removed from
6052 the channel. It also checks whether the channel has local clients
6053 on the channel anymore. If it does not have then the channel entry
6054 is removed as it is not needed anymore.
6056 * The silc_server_notify now checks on JOIN notify whether the joining
6057 client is one of locally connected or global. If it is global then
6058 the channel has now global users on the channel and that is marked
6059 to the channel entry. Also, it now saves the global client to
6060 global list who is joining and JOINs it to the channel. This is
6061 for normal server, that is.
6063 Changed silc_server_send_notify_on_channel,
6064 silc_server_packet_relay_to_channel and
6065 silc_server_packet_send_to_channel check if we are normal server
6066 and client has router set (ie. global client) do not send the
6067 message to that client, as it is already routed to our router.
6069 * Implemented LEAVE notify type handling in silc_server_notify
6072 * Tested LEAVE command in router environment successfully. Tested
6073 with two routers, two servers and two clients.
6077 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6079 * Implemented SIGNOFF notify type handling in silc_server_notify
6082 * silc_server_remove_id now removes the client entry from all channels
6083 it has joined and thusly sends SIGNOFF notify type.
6085 * Rewrote the NAMES list generation in server by removing two excess
6086 loops. The lists are created now inside one loop.
6088 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6090 * silc_server_remove_channel_user checks now also global list
6091 for channel and client.
6093 * silc_server_new_channel_user checks now both local and global
6094 list for channel and client. Fixed a bug in client id decoding.
6095 Used to decode wrong buffer.
6097 * silc_server_channel_message checks now both local and global
6098 list for channel entry.
6100 * Tested channel joining (hence JOIN) in router environment
6101 successfully. Tested with two routers, two servers and two
6104 * Tested channel message sending in router environment successfully.
6106 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6108 * Added silc_server_save_channel_key into server.[ch] to save the
6109 received channel key in Channel Key payload processing. It is
6110 also used in JOIN command reply handling.
6112 Equivalent function silc_client_save_channel_key added into
6113 client.[ch] into client library.
6115 * Changed JOIN command reply to send information whether the channel
6116 was created or not (is existing already) and the channel key
6117 payload. Changed protocol specs accordingly.
6119 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6120 the request was sent by ID and not by nickname. Crashed on
6123 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6125 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6126 now correctly save the received data.
6128 * silc_server_free_sock_user_data now notifies routers in the
6129 network about entities leaving the network.
6131 At the same time implemented functions silc_server_remove_id
6132 and silc_server_send_remove_id to receive and send REMOVE_ID
6133 packets. The packet is used to notify routers in the network
6134 about leaving entities. The ID removed will become invalid in
6137 * Added function silc_idlist_del_server into server. Removes and
6138 free's server entry from ID list.
6140 * silc_server_private_message function now checks, if we are router,
6141 that the destination ID really is valid ID, naturally.
6143 * In router when NEW_ID packet is received (for new client) the
6144 hash of the Client ID is saved in the ID Cache but the
6145 client->nickname is set to NULL, instead of putting the hash
6148 IDENTIFY command now also checks that client->nickname must be
6149 valid. If it is not if will request the data from the server who
6150 owns the client. Added new function
6151 silc_server_command_identify_check.
6153 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6154 to set the command to already allocated Command Payload.
6156 * Tested private message sending in router environment with two
6157 routers, two servers and two clients. Fixed minor bugs and now
6160 * Fixed segfault from client's NAMES command. Used to crash if
6163 * Forwarded packets must not be routed even if it is not destined
6164 to the receiver. Changed server code comply with this.
6166 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6168 * Added `require_reverse_mapping' boolean value to ServerParams
6169 structure. If TRUE (not default) the server will require that
6170 the connecting host has fully qualified domain name.
6172 If the reverse mapping is not required and hostname could not be
6173 found the IP address is used as hostname.
6175 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6177 * Implemented version string checking to both client and server.
6178 The check is incomplete currently due to the abnormal version
6179 strings used in development version of SILC.
6181 * Changed all command functions in server to use the new
6184 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6186 * Changed char *data to unsigned char *data in ID Cache system to
6187 support binary data as ID Cache data. Changed code to support
6188 binary data in lib/silccore/idcache.c.
6190 * Renamed silc_server_packet_relay_command_reply to
6191 silc_server_command_reply as it is normal packet receiving
6192 function. Rewrote the function to accept command replys for
6193 servers and not only for clients.
6195 * Mark remote router always as registered server if we are connecting
6196 to it. Otherwise, commands sent by the router to us are ignored.
6198 * All ID List find routines now returns the ID Cache Entry pointer
6199 as well if requested.
6201 * WHOIS command works now in router environment, tested with two
6202 routers, two servers and two clients.
6204 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6205 in router environment (as it is almost equivalent to WHOIS) but
6206 hasn't been tested thoroughly. Added new functions:
6208 silc_server_command_identify_parse
6209 silc_server_command_identify_send_reply
6210 silc_server_command_identify_from_client
6211 silc_server_command_identify_from_server
6213 * Disabled route cache adding because adding two different ID's with
6214 same IP replaces the old cache entry thus giving wrong route.
6215 The entry->router->connection is always the fastest route anyway
6216 so route cache may not be needed. Of course, new routes maybe
6217 established after receiving the ID when the entry->router->connection
6218 might not be anymore the most optimal.
6220 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6222 * Add route cache for received ID for fast routing.
6224 * Added silc_server_packet_route to route received packet on router
6225 that is not destined to us.
6227 * Renamed silc_server_get_route to silc_server_route_get.
6229 * Added id_string and id_string_len fields into SilcServer to
6230 include encoded ServerID for fast comparing without excess
6231 encoding of the ID's.
6233 * Cleaned up WHOIS command on server side. Added following static
6236 silc_server_command_whois_parse
6237 silc_server_command_whois_check
6238 silc_server_command_whois_send_reply
6239 silc_server_command_whois_from_client
6240 silc_server_command_whois_from_server
6242 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6243 arguments in command replies. All command functions should be
6244 updated to use this macro.
6246 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6248 * Minor typo fixes on command reply handling on server.
6250 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6252 * Added silc_server_command_add_to_channel internal routine to add
6253 the client to the channel after router has created the channel and
6254 sent command reply to the server.
6256 * Added generic silc_server_send_command to send any command from
6259 * Use static buffer with ID rendering instead of duplicating data.
6261 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6263 * Fixed a channel user mode bug when joining to a channel server gave
6264 everybody channel founder rights, oops.
6266 * We mark ourselves as the router of the incoming server connection
6267 if we are router ourselves. This way we can check in some packet
6268 sending functions whether it is locally connected server. For
6269 incoming router connections we put NULL.
6271 * For router sending packets locally means now always sending the
6272 packet cell wide; to local clients and local servers. For normal
6273 server sending packet locally means sending it to only local
6276 * Fixed the JOIN command to really work in router environment. If the
6277 channel is created it is always created by the router. Router is
6278 also responsible of making the initial joining to the channel,
6279 sending JOIN notify to the sending server and distributing
6280 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6281 does not exist server doesn't do anything else but forward the
6282 command to the router which performs everything.
6284 * Added silc_server_send_channel_key function to send the Channel Key
6287 * Added silc_server_create_channel_key to create new channel key. The
6288 channel key is now re-generated everytime someone joins or leaves
6289 a channel, as protocol dictates. Note: channel->key_len is the
6292 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6294 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6295 packet_receive.[ch] to separate packet sending and receiving
6296 routines. The server.[ch] now includes everything else including
6297 actual packet processing (writing and reading data) and other
6300 Renamed silc_server_private_message_send_internal to
6301 silc_server_send_private_message. The routine is still though
6302 used only to relay private messages as server does not send
6303 private messages itself.
6305 Renamed silc_server_new_channel to silc_server_create_new_channel
6306 and added new function sicl_server_new_channel that handles the
6307 incoming New Channel packet. Added also new sending function
6308 silc_server_send_new_channel to send New Channel Payload.
6310 * Added new function silc_server_notify to process incoming notify
6311 packet to the server/router. Server may then relay the notify
6312 to clients if needed.
6314 * Added new function silc_server_new_channel_user to process incoming
6315 New Channel User packet. Router will redistribute the packet and
6316 send JOIN notify to its local clients and locally connected servers
6317 if needed. Normal server will send JOIN notify to its local client
6318 on same channel when received this packet. Added also corresponding
6319 sending function silc_server_send_new_channel_user to sent the
6322 * Added boolean route argument to send_notif_to_channel and
6323 packet_send_to_channel functions to attempt to route the packet
6324 if it is TRUE and send only locally if it is FALSE.
6326 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6328 * silc_server_replace_id now broadcasts the received replace ID
6329 packet if it is not broadcast packet already. The router must
6330 broadcast to inform other routers about changed ID.
6332 * Added backpointer to server's router into SilcServer context in
6333 silcd/server_internal.h.
6335 * Fixed silc_server_packet_broadcast to send correct broadcast
6338 * The channel key is now distributed to the local client as soon
6339 as it is received from the router (in router environment) so that
6340 no other packet may be sent for the channel until client has
6343 * silc_server_remove_channel_user now broadcasts the received
6344 Remove Channel User packet if it is not broadcast packet already.
6345 The router must broadcast to inform other routers about removed
6348 * Added users field into SilcPacketContext that is a reference count
6349 of the context. One can increase the reference count by calling
6350 silc_packet_context_dup which is now changed to just increase the
6351 reference count instead of duplicating the data. The reference
6352 count is decresed by calling silc_packet_context_free that will
6353 free the data after the reference count hits zero.
6355 For now on the packet context and everything allocated into it
6356 (including the raw packet from network) must be freed by calling
6357 the new silc_packet_context_free function. Added also new function
6358 silc_packet_context_alloc that must be used now to allocate the
6359 context. This also means that if a routine is asynchronous from
6360 silc_[client/server]_packet_parse_type the packet context must
6361 be duplicated by calling silc_packet_context_dup. Otherwise it
6362 gets free'd after silc_[client/server]_packet_parse_type returns.
6363 Also, one must remember that if packet is duplicated then its
6364 reference count must be decresed by calling the free function as
6365 many times as it was duplicated.
6367 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6368 from both client and server.
6370 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6372 * Made joining to a channel working in router environment.
6374 * Cleaned up JOIN command on server side and create function
6375 silc_server_command_join_channel internal routine to make the
6378 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6380 * Changed silc_command_pending list to SilcDList. Also, added
6381 `ident' field to SilcServerCommandPending structure to identify
6382 the reply and to call correct callback.
6384 Added silc_server_command_pending_check function to replace the
6385 corresnponding macro. The silc_command_pending list is not
6388 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6389 to set identifier to previously allocated Command Payload. It
6390 is used to set identifier for command when resending Command
6393 * Added silc_command_payload_encode_payload to encode Command
6394 Payload buffer from SilcCommandPayload structure.
6396 * Added silc_argument_payload_encode_payload to encode Argument
6397 payload buffer from SilcArgumentPayload structure.
6399 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6401 * Changed WHOIS command to support router connection on server side.
6402 The whois request is always sent to router unless the server is
6403 standalone server. After server has received the reply from the
6404 router will it send the reply to the client.
6406 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6407 broadcast received broadcast packet. The function is used only
6408 by router. The broadcast packet is always sent to the router's
6411 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6412 render given ID to printable string, for log files for example.
6414 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6416 * Made basic router to router connections working. At least they
6417 can now connect to each other but nothing really works the way
6418 they are supposed - yet.
6420 * Added new initiator token to RouterConnection configuration
6421 file in silcd/serverconfig.[ch]. It is used to tell whether we
6422 are the initiator to the remote router or whether we'll expect
6423 the other end to connect.
6425 * Moved registering of listener task to silc_server_init, hence
6426 the server starts listenning as soon as it is run, even if it
6427 does not have connections to other routers. Let's see how well
6430 * Changed default connection retry timeouts for more suitable in
6433 * Removed cipher and such arguments from silc_idlist_add_client
6434 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6435 Added new function silc_idlist_add_data to add the keys and stuff
6438 * Added SilcIDListData structure and added it to SilcClientEntry
6439 and SilcServerEntry as their first field in the structure. This
6440 way we can explicitly cast the ID entries to the SilcIDListData
6441 structure and get common data for the entries. In past, we had
6442 to first check what type of connection it is and then cast it to
6443 correct ID entry type. Now, we can directly cast the opaque
6444 pointer to the SilcIDListData (no matter what ID entry it actually
6445 is) and get the data needed.
6447 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6449 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6450 in some circumstances even if threre were timeout tasks, though not
6451 IO tasks, but tasks anyway. Now fixed.
6453 * Defined SilcServerConnection structure to hold connection specific
6454 stuff about directly connected servers and routers. The definition
6455 is currently in silcd/server_internal.h. I thought about having
6456 a bit more important role fro this struct but for now it is used
6457 only when connecting to other server (or router actually).
6459 * Added connecting retry support in server when connecting to
6460 router(s). The retry feature implement exponential backoff
6461 algorithm. Also, added SilcServerParams structure to hold default
6462 parameters for server. For now, it include these retry settings
6463 and are hard coded. After server is moded to be as Silc Server
6464 Library this structure will be more important.
6466 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6468 * Changed client librarys channel->clients table to SilcList and
6469 changed code accordingly.
6471 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6473 * Changed client's channel table to SilcList and changed code
6474 accordingly. Also changed SilcChannelClientEntry to include back-
6475 pointer to the channel so that client entry can use that structure
6476 as list as well and we have fast cross-reference to the channel.
6477 This change dramatically decreased the complexity of channel
6478 handling with client entry and vice versa (removed one extra
6479 loop when searching for channel entry from many functions).
6481 * Changed server->sim from table to SilcDList and changed code
6484 * NAMES command can now be used from user interface. It will show
6485 the user list on the channel, neatly.
6487 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6488 Code now saves realname of the user if it becomes available.
6490 * Renamed configure.in to configure.in.pre and made ./prepare
6491 script to automatically add correct version string to
6492 configure.in which it creates from configure.in.pre.
6494 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6496 * NAMES command reply now shows users mode with the nickname when
6499 * Moved silc_client_ch[u]mode[_char] functions from
6500 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6501 place sucks, they are utility functions and should be in some
6504 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6506 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6509 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6513 * Added TRQ (efficient deque and list library) into lib/trq. This is
6514 a very good list library that is currently used in the SILC. Defined
6515 SilcList API over the library because I didn't like the API very
6516 much. See lib/trq/silclist.h for the API and examples of how to
6517 use the API. Fixed various places in the code to use the new
6518 SilcList API. The SilcList is meant for lists that has a structure
6519 already defined as a list. It is not suitable to add just some
6520 context to the list (in TRQ, the context is the list actually).
6522 So, I defined SilcDList that can be used for the purpose where
6523 predefined list structure does not exit. This can be used as
6524 such list. Now some context just can be added to the SilcDList.
6525 Currently this list is not used in the SILC just yet, though there
6526 are a lot places where this can replace dynamically allocated
6527 tables and I will fix these places, later, to use SilcDList.
6528 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6529 and use TRQ internally).
6531 Also fixed some annoying warning messages that the original TRQ
6532 code generated. Also minor changes to TRQ's Makefile.in.
6534 * Added support for querying by Client ID to both WHOIS and
6535 IDENTIFY commands into server, as required by the protocol.
6537 * Removed method function pointers from SilcBuffer structure. They
6538 weren't used to anything and just increased the context size for
6539 no good reason. This change also made silc_buffer_alloc and
6540 silc_buffer_free functions inline functions.
6542 * Disabled command flooding detection support until it's fixed so
6543 that it accepts commands in but does not execute them more than once
6546 * Added silc_net_localhost(), to return local hostname, into
6547 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6548 that must be initialized before calling silc_client_init.
6550 * Added new function: silc_server_send_notify_on_channels to send
6551 notify messages to all channels client has joined. It is assured
6552 that the message is sent only once per client.
6554 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6555 lib/silcutil/silcutil.[ch] as silc_format function. The new
6556 function is generic and is used by server as well, not only by
6557 the logging routines.
6559 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6560 the provided version string was not acceptable. Added new function:
6561 silc_ske_check_version into lib/silcske/silcske.h. The function
6562 must be implemented by the application (client or server) and it
6563 does not reside in the SKE library. The function checks the version
6564 string remote end sent.
6566 * Added back pointers (to opaque context and to SilcSocketConnection)
6567 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6569 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6570 duplicate packet context structure.
6572 * Changed `notify' client operation to send same arguments as client
6573 receives from server except for ID's. ID's are mapped to correct
6574 ID entry and that is returned. Also, if channel entry is not sent
6575 by server but the notify is for channel the channel entry is sent
6576 to application (otherwise application doesn't know that it is for
6577 channel (library gets it from packet's Destination ID)).
6579 * Added silc_client_remove_from_channels into client library to
6580 remove a client from all channels it has joined to. Used when
6581 received SIGNOFF notify from server. Added also new function
6582 silc_client_replace_from_channels to replace old ID entry with
6583 new ID entry on all channels. Used when received NICK_CHANGE
6586 * Fixed ID Cache list handling in silc_idlist_get_client in
6587 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6588 to get (or query) client by ID.
6590 * Updated TODO list.
6592 * Added connection authentication status message defined by the
6593 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6594 support for these into the code in client and server side.
6596 * Added generic function silc_client_send_command to send any command
6597 with variable argument list. Application should use this function
6598 to send commands if the command functions provided by the library
6599 does not suite for the application's user interface needs.
6601 * Added new `failure' client operation. Application is notified about
6602 received failure packet if client is executing a protocol. In this
6603 case the protocol's execution has failed.
6605 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6606 is required by the protocol.
6608 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6609 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6612 * Added status flag to SilcSKE object to indicate realtime status
6613 of the SKE protocol.
6615 * Application receives now exactly same command reply arguments as
6616 the library receives from server. However, if ID is received the
6617 corresponding ID entry is returned to the application (eg. Client
6618 ID is mapped to correct SilcClientEntry entry and that is returned).
6619 Changed command_reply client operation due to this change.
6621 * Changed all ID's in commands and in command replys as ID Payloads.
6622 Change affected both client and server side codes.
6624 All ID's sent in SILC network (with execption of ID's in SILC
6625 Packet header) are sent in ID Payload to support variable length
6628 * Server now notifies nick changes and notifies all clients on
6629 the channels about the new nickname (about the new Client ID,
6632 * Implemented CMODE command to change channel modes. Supports all
6633 channel modes defined by the protocol specs except ban and invite
6634 lists. (Also, private channel key mode is supported but support for
6635 setting private channel key in client is missing, thus, this mode
6636 has no effect on client side (except that server requires that the
6637 client uses private channel key and normal channel traffic does not
6640 Also, invite mode works per se, but INVITE command does not work
6641 yet correctly, so you can set channel as invite only channel but
6642 inviting clients to the channel does not work (it is yet to be
6643 thought what's the best way to do it).
6645 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6646 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6647 Implemented CUMODE command to change user's mode on the channel.
6648 Supports all modes defined by the protocol specs.
6650 * Added NAMES command reply to return users modes on the channel.
6652 * Removed unnecessary and slow ciphers from lib/silccrypt.
6654 * Set SO_KEEPALIVE option to connection sockets by default.
6656 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6658 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6659 redefined the Notify Payload into protocol specs.
6661 * Added silc_id_payload_parse_id to get ID directly from raw
6664 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6666 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6667 accept searching by Client ID as well.
6669 * Added support for LEAVE and SIGNOFF notify types in client library.
6671 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6672 to parse ID Payload from raw data.
6674 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6676 * Added flags parameter into silc_ske_assemble_security_properties
6677 function in lib/silcske/silcske.[ch].
6679 * Changed notify client operation to fit better for notify messages
6680 sent by server. The notify payload received from server is now
6681 passed to the application (after parsing it to SilcNotifyPayload).
6682 It is application's responsibility to retrieve the arguments
6683 from the payload and show the message the way it wants. The message
6684 sent by server is implementation specific.
6686 * Changed public keys to comply with the protocol specification.
6687 Old public keys are not supported anymore and are not compatible.
6689 * Removed nickname from Channel Payload as the latest draft removed
6690 it. The client must resolve the nickname from the NAMES command
6691 reply received when it joined the channel.
6693 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6695 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6697 * Fixed some errors in protocol specification drafts.
6699 * Created lib/silccore/silcnotify.c to implement Notify Payload
6700 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6701 generic payloads described by protocol specifications. The file
6702 includes implementations for ID Payload and Argument Payload.
6704 * Changed Command Payload implementation to use the new Argument
6705 Payload. Changed command_xxxx_payload to command_payload_xxxx
6706 to comply with SILC coding conventions.
6708 * Added suppport for Argument Payload handling in Notify Payload
6709 implementation as protocol requires it. Added the new support
6710 into server and client lib as well.
6712 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6714 * Added support for multiple nicknames on same channel. [n] is
6715 added locally to the nickname if there are more than one same
6716 nicknames on the channel.
6718 * Server now sends all nicknames that matched WHOIS request.
6719 Client also shows the list received from server.
6721 * Added TOPIC command to client side. User can now set and show
6722 current topic on channel.
6724 * Added MOTD command to client and server. Also, server sends the
6725 motd when client connects to the server.
6727 * Changed version strings to comply ISO 8601.
6729 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6731 * Fixed protocol error handling in client library. It should now
6732 cope even if the SKE fails for some reason.
6734 * Made new protocol specification drafts for submitting to IETF.
6736 * Implemented TOPIC command to server in silcd/command.c.
6738 * Added two new notify types into lib/silccore/silcnotify.h:
6739 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6740 notify nickname change and topic setting/change on a channel.
6742 * API change of command_reply operation in client library. The
6743 application gets now the status type received from server as well.
6745 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6747 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6749 * Cras fixed and optimized the packet handling even further and
6750 it should work now. Minor change to the prototype of function
6751 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6753 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6755 * Added new function into lib/silcutil/silcschedule.[ch]:
6756 silc_schedule_with_fd to select() a specified fd. The function
6757 returns after timeout expires or data arrives or goes. The
6758 function is used by packet routines to wait that all data is
6759 received from network.
6761 * Fixed data reading from network in lib/silccore/silcpacket.c.
6762 The code now assures that all data is read from the fd and then
6763 continues packet processing. This was a bug fix since the code
6764 used to drop some data in some circumstances.
6766 * Added new function into lib/silcclient/client.[ch]:
6767 silc_client_start_key_exchange to start key exchange after
6768 connection has been established to server. The code internally
6769 now uses this funtion but its main purpose was to provide it
6770 for applications that perform their own connecting. After
6771 application has created a connection it merely calls this
6772 function to start the key exchange between client and server.
6773 The library takes care of everything else after that.
6775 Updated also lib/silcclient/README to explain the usage of
6778 * Do not send to application information that connection has
6779 been established. Application gets notified it by connect
6782 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6784 * Applied cras's patch to add silc_schedule_one function. The
6785 function runs scheduler once and returns.
6787 * Fixed the scheduler after cras messed it up. The timeout
6788 handling works now as it's supposed to work.
6790 * Added into lib/silccore/ silcnotify.h to include notify
6791 message types support. Changed silc_server_send_notify*
6792 functions, in server.[ch], to support those new notify types.
6793 Added the support for the notify types into client library,
6794 as well. Added new notify client operation into ops.h in
6797 * Changed silc_server_packet_send_to_channel to send normal
6798 packets instead of just channel message packets. The function
6799 is now used to send the notify packets to channels. It is not
6800 used to send channel message packets anymore, as server never
6803 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6804 va_arg()s as it seems to require it nowadays. I guess, if SILC
6805 is compiled with older va_arg() the new code should work anyway.
6807 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6809 * Splitted core library. Core library (lib/silccore) includes
6810 now only SILC protocol specific core (and common) components.
6811 Created new utility library (lib/silcutil) that includes more
6812 generic purpose stuff. The stuff for util library was taken
6813 from the old core library. This was minor and easy split.
6815 * Created SILC Client Library (lib/silcclient) that includes
6816 implementation of the SILC client without user interface. This
6817 was major move from silc/ directory. The code has been changed
6818 so that it is transparent towards the user interface. The
6819 silc/ directory includes now the same user interface as before
6820 and it uses the new client library. Read lib/silcclient/README.
6821 Basicly, the client library performs everything else related
6822 to SILC except user interface handling. Also, configuration
6823 files are considered to be part of user interface and library
6824 does not handle them.
6826 This change also changed a lot of structures, function naming etc.
6827 Most important change was that SilcClientWindow object was
6828 renamed to SilcClientConnection in the client library. Created
6829 also new file lib/silcclient/ops.h. Also added new files
6830 silc/local_command.[ch] and silc/client_ops.[ch].
6832 All these changes were made to make it easier for user interface
6833 designers to create what ever user interface for the SILC client
6836 It is also expected that the server will be moved to lib
6837 directory as well and SILC Server Library will be created;
6838 sometimes in the future.
6840 * Removed Local commands from lib/silccore/silccommand.h as
6841 they are application specific and new client library does not
6842 handle any of those anymore.
6844 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6845 old client implementation in silc/.
6847 * Added support for callback functions in SILC_LOG_* macros.
6848 Application can now set its own callbacks that will be called
6849 instead of using the default functions that will always print
6850 the debug messages to stderr (or stdout). Also, debugging can
6851 now be disabled by setting silc_debug to FALSE and re-enabled by
6852 setting it to TRUE. Note, that logging will still work even
6853 if debugging is disabled.
6855 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6856 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6857 silc_log_reset_debug_callbacks.
6859 * To enable debugging in silc client one must give now -d
6860 option on command line.
6862 * Changed silc_schedule_init to automatically allocate task queues
6863 if they are not allocated before calling it.
6865 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6867 * Added GMP 3.1 into math library.
6869 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6871 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6872 a channel in SILC network. The packet is used by servers and
6873 routers to notify other routers that user has left a channel.
6874 This little feature was missing until now. Added the feature
6875 to protocol specification as well.
6877 Added functions: silc_server_send_remove_channel_user and
6878 silc_server_remove_channel_user into server.[ch].
6880 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6881 lib/silccore/silcpacket.h. However, they are not implemented
6884 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6886 * Fixed joining to a channel and sending channel messages
6887 between server and router. The channel message sending should
6888 now work inside a cell.
6890 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6892 * Fixed the private message sending between server and router.
6893 The private message sending should now work inside a cell.
6895 * Added silc_server_replace_id into server.[ch] to replace
6896 existing ID in the SILC network.
6898 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6899 and silc_idlist_replace_server_id into idlist.[ch] in server.
6901 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6903 * Fixed the server to server connections. Server can again now
6904 connect to router. Router to router connections probably does
6907 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6909 * Added dynamic protocol registering support. Now protocols can
6910 registered and unregistered on the fly. Patch by cras.
6912 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6914 * Added lib/contrib directory to hold routines that some platforms
6915 don't have but are needed by SILC.
6917 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6918 into lin/contrib to provide getopt() and getopt_long() for
6919 those who don't have it.
6921 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6923 * Added AWAY command to client. When away message is set and
6924 client receives a private message packet the client automatically
6925 replies to the sender with the away message.
6927 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6928 bug seemed to be the cause of recent problems when compiling
6931 * Added version detection support to SKE protocol specification
6932 and added the new changes to the SKE implementation as well.
6933 There were other minor changes in the SKE protocol as well.
6935 Many changes in lib/silcske/silcske.[ch] and in
6936 lib/silcske/payload.[ch].
6938 * Added ^U functionality, clear input line. Patch from cras.
6940 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6942 * Mainly small bugfixes on core library. Fixed some debugging
6943 logging and buffer overflow in silclog.c.
6945 * Updated config.sub and config.guess on the distribution tree.
6947 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6949 * Added command lagging support in server. Client may execute
6950 commands now only once in two seconds.
6952 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6954 * Optimized packet reception. MAC computation and checking is now
6955 also more optimized. A lot previously duplicated code is now
6956 used as generic by both client and server.
6958 * Fixed key pair generation in clientutil.c
6960 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6962 * Added into lib/silccore/silcbufutil.[ch] new function;
6963 silc_buffer_realloc.
6965 * Moved generic packet sending/encryption functions to
6966 lib/silccore/silcpacket.[ch] from client and server. Some
6967 rewriting of the functions.
6969 * Moved all generic packet reception/decryption functions to
6970 lib/silccore/silcpacket.[ch] from client and server. The
6971 packet processing is now much cleaner in both client and server.
6972 These were major changes in both client and server.
6974 * Created many common functions in server to do packet sending.
6975 Previously code were duplicated a lot, this has been removed
6978 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6980 * Rewrote major parts of the ID cache system. Don't know
6981 whether it is better now or not but at least the API is more
6984 * Major rewrite on ID cache stuff on client because of the ID
6985 cache API changes. Added idlist.c to client.
6987 * Also major rewrite on ID cache stuff on server as well.
6988 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6989 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6990 in hand, instead they are all put into the ID cache system now.
6991 All server_idlist_* routines uses ID cache now instead of
6992 traversing its own lists (those lists does not exist anymore).
6993 SilcIDList though still exists. Also, SilcXXXEntry's are
6996 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6998 * Finally made the SKE implementation compliant to the protocol
6999 specification. All mp integers are now binary encoded as
7000 opposed being HEX encoded.
7002 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7005 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7006 functions: silc_[encode/decode]_pem. Also added function
7007 silc_encode_pem_file to PEM encode with newlines ('\n') for
7010 * SILC public keys are now encoded either PEM or binary. Same
7011 option is for private keys as well. By default private keys
7012 are binary encoded and public keys PEM encoded. Silly HEX
7013 encoding were removed.
7015 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7016 function to create fingerprints.
7018 * Fixed a bug in SHA1; does not change the original data anymore.
7020 * Partly implemented INFO command on client and server side.
7021 Fixed CLEAR command. Changes to SERVER command; show current
7022 server(s) when giving command without arguments. Added
7023 VERSION command to client.
7025 * Added check to server that unregistered connections cannot
7026 execute commands (unless it is specificly allowed).
7028 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7030 * Fixed screen refresh.
7032 * Fixed channel joining bug from client. On some circumstances
7033 client tried to join to a channel it had already joined.
7035 * Added public key verification process into client's protocol.c.
7036 The client now verifies the public key from user and saves
7037 it into ~./silc/serverkeys/ directory.
7039 Added into: clientutil.[ch]: silc_client_verify_server_key.
7041 * Changed SKE protocol's silc_ske_initiator_finish function
7042 to accept callback function that verifies the received public
7043 key. Removed old silc_ske_verify_public_key function.
7045 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7047 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7048 silc_pkcs_private_key[_data]_set.
7050 * Made the password and public authentication more cleaner in
7051 server's protocol.c.
7053 * Removed historic and obsolete protocol `channel_auth' from
7054 both client and server.
7056 * Removed wrong way of sending command status messages from
7057 server to client in server's command.c. The old way violated
7058 protocol specification.
7060 Changes to silccore/silccommand.[ch]: removed
7061 silc_command_encode_status_payload -> not needed anymore,
7062 changed silc_command_encode_payload_va to accept extra
7063 argument on variable argument list. The argument type must
7064 now be provided to the function. Also, added new function:
7065 silc_command_encode_reply_payload_va which is same as
7066 normal command_encode_payload_va except command status type
7067 is provided as extra argument.
7069 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7071 * Added ~./silc directory handling. The directory includes the
7072 public and private keys for the client.
7074 Added silc_client_check_silc_dir, silc_client_create_identifier
7075 and silc_client_load_keys.
7077 * Implemented SILC protocol compliant public key. Added public
7078 and private key saving to and loading from files.
7080 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7081 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7082 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7083 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7084 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7086 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7087 silc_pkcs_load_[public/private]_key.
7089 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7091 * Added silc_server_get_route (route.[ch]) to get connection
7092 data for the fastest route for given ID.
7094 * Implemented INVITE command on client and server. The command
7095 were re-defined in the SILC Protocol Specification and the
7096 implementation now complies with the specification.
7098 * Implemented PING command on client and server.
7100 * Implemented NAMES command on client and server. The server side
7101 supports currently only normal server not router server yet.
7102 Some changes to NAMES definition in SILC protocol specification.
7104 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7106 * Implemented LEAVE command on client and server.
7108 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7109 again. This change was made to the protocol as well. Server
7110 should not violate the protocol specification anymore.
7112 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7114 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7115 was tested. SOCKS4 was not but should work anyway.
