3 * ROBOdoc documented the lib/silcske/silcske.h, and improved
4 the SKE interface a bit.
6 * Fixed padding problem in PKCS#1. The padding was not actually
7 random since the random number generator was used incorrectly.
8 This security bug affects only when encrypting with PKCS#1, and
9 it is not currently used at all in SILC. SILC only use signing
10 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
12 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

24 key_exchange_timeout, conn_auth_timeout, connections_max,
27 Implemented all the new config settings handling in the server.
29 Optimized the use of SKE Mutual flag usage. Use it only
30 if connection authentication protocol is not based in public
33 Renamed all SilcServerConfigSection* to SilcServerConfig*
34 to have a bit shorter names.
36 Affected files silcd/serverconfig.[ch], server.[ch], and
39 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

79 keepalive_secs, reconnect_count, reconnect_interval,
80 reconnect_interval_max, reconnect_keep_trying and
81 require_reverser_lookup. Added ConnectionParam block, and
82 implemented the connection parameters when connecting as
83 initiator and when accepting connections as responder.
85 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
86 whether given configuration value has been given already.
88 Affected files silcd/serverconfig.[c], server.[c].
90 * Splitted the doc/example_silcd.conf.in. Separated the crypto
91 algorithm parts and created new file silcalgs.conf, that
92 is now included from the example_silcd.conf.in.
94 * Optimized the silc_server_connect_to_router_second to take
95 the connection configuration object from the SilcServerConnection
96 object instead of finding it during the connecting phase.
97 Added the configuration object to SilcServerConnection struct.
98 Affected files silcd/server_internal.h, server.c.
100 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

112 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
114 * Unified the serverconfig.[ch]'s helper function interface.
115 Affected file silcd/serverconfig.[ch].
117 * Removed doc/example_silc.conf.in since it is redundant.
118 The make install will now install irssi/silc.conf file.
120 * Added new Passphrase and Publickey authentication methods to
121 config file, allowing both public key and passphrase based
122 authentication to be set at the same time.
124 Added `prefer_passphrase_auth' setting in config file which
125 can be used to set to prefer passwd auth if both passwd and
126 public key is set. If not set, public key is preferred.
127 This has effect only when being initiator (responder will try
130 Added support for authentication with passphrase and public key
131 at the same time. The passphrase is tried first always since
132 it is faster to check.
134 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
136 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

178 hash algorithm. Affected file lib/silccrypt/silcrng.c.
180 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
182 * Fixed the file transfer's key agreement payload to include
183 zero port also if the hostname is NULL because it could not
186 Call file transfer monitor callback now also if error occurs
187 during key agreement protocol.
189 Changed the silc_client_file_send interface to return the
190 SilcClientFileError instead of session id. The session ID
191 is returned into pointer provided as argument.
193 Check that the file exists locally before sending the
194 file transfer request at all.
196 Affected file lib/silcclient/client_ftp.c, silcapi.h.

208 file lib/silcutil/silclog.c.
210 * Fixed the channel message payload decryption in the function
211 silc_channel_message_payload_decrypt to not modify the original
212 buffer before it is verified that the message decrypted
213 correctly. Otherwise, next time it is called with correct
214 channel key it won't encrypt since the payload is corrupted.
215 Affected file lib/silccore/silcchannel.c.
217 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

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

318 * Removed TRQ from lib/trq, not needed anymore.
320 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
321 with server connections. Later this will be configurable
322 in config file after new config file is done. Affected file
325 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
327 * Fixed a crash in server related to channel announcements.
328 Affected file silcd/server.c.
330 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
332 * Fixed memory leaks in silc_server_create_new_channel*
333 functions. Affected file silcd/server.c.
335 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
336 which ID was changed. This way the router will send the
337 user list for the channel again, and server won't be in
338 desync in some rare circumstances. Affected file is
339 silcd/packet_receive.c.
341 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
343 * Check for NULL socket pointer in the function

352 * Fixed some header addition to Toolkit distribution in
353 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
355 * Added lib/silcclient/client_ops_example.h as an template
356 file for application programmers to quickly start using
357 the SilcClientOperation functions in their application.
358 Updated the lib/silcclient/README as well to tell about this
359 nice file made available.
361 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
363 * Call silc_server_remove_from_channels when removing client
364 entry when NO_SUCH_CLIENT_ID was received. Affected file
365 is silcd/command_reply.c.
367 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
369 * Added server & router operator statistics updating. Affected
370 file silcd/packet_receive.c and silcd/command.c.
372 * Fixed the SERVER_SIGNOFF notify handling on normal server
373 not to save the history information for clients. Same was
374 fixed earlier in remove_clients_by_server function, but not
375 here. Affected file silcd/packet_receive.c.
377 * Raised the default connection-retry count from 4 to 7 in
378 server. Affected file silcd/server.h.
380 * Cancel any possible reconnect timeouts when we start the
381 key exchange. Affected file silcd/server.c.
383 * Do not reconnect on connection failure when SCONNECT was
384 given. Affected files silcd/server.[ch].
386 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
388 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
390 * Fixed the NICK command to always give the unformatted
391 nickname to the one giving the NICK command. If unformatted
392 nickname is cached already it will be formatted and the
393 local entry will always get the unformatted nickname.
394 Affected file lib/silcclient/idlist.c.
396 * Fixed some double frees from client library commands.
397 Affected file is lib/silcclient/command.c.
399 * Fixed CUMODE command in server to assure that no one can
400 change founder's mode than the founder itself, there was a
401 little bug. Affected file silcd/command.c.
403 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
405 * Removed the SilcClientCommandDestructor from the client
406 libary, it is not needed anymore. Affected files are
407 lib/silcclient/silcapi.h, command[_reply].[ch],
408 client_notify, idlist.c.
410 * Fixed GETKEY command to first resolve client, and then
411 resolve the server only if the client was not found, instead
412 of resolving both at the same time. Affected file is
413 lib/silcclient/command.c.
415 * Added silc_client_start_key_exchange_cb and lookup the
416 remote hostname and IP address before starting the key
417 exchange with server. The affected file is
418 lib/silcclient/client.c.
420 * The server's public key is now saved using the IP address
421 of the server and not the servername for the filename.
422 The hostname public key filename is checked as an fall back
423 method if the IP address based filename is not found.
425 Fixed the GETKEY command to save the fetched server key
428 Print the remote server's hostname now when new key is
429 received during connection process. Affected file is
430 irssi/src/silc/core/client_ops.c.
432 * Return always our own public key to the client if it asks
433 for it with GETKEY command. Affected file silcd/command.c.
435 * Removed the use_auto_addr variable from default config
436 file since it was in wrong section. Affected file is
439 * Fixed TOPIC_CHANGE notification to not route it when it
440 was sent using silc_server_send_notify_to_channel function.
441 Affected file silcd/command.c.
443 * Fixed silc_server_send_notify_kicked to send the kicker's
444 Client ID also, it was missing. Affected files are
445 silcd/command.c, silcd/packet_send.[ch].
447 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
449 * Do not save client history information in SERVER_SIGNOFF.
450 Fixes the bug in normal server that it does not detect
451 the client becoming valid after the server becomes back
452 online. Affected file silcd/server_util.c.
454 * Added `sock_error' field into the SilcSocketConnection
455 context. When error occurs during socket operation (read
456 or write) the error is saved. Added also new function
457 silc_socket_get_error to return human readable socket error
458 message. Affected files are lib/silcutil/silcsockconn.[ch],
459 lib/silcutil/unix/silcunixsockconn.c, and
460 lib/silcutil/win32/silcwin32sockconn.c.
462 * The server now prints the socket error message in the
463 signoff for client. Affected file silcd/server.c.
465 * Fixed the `created' channel information sending from router
466 to server in JOIN command. Checks now whether the channel
467 really was created or not and set it according that.
469 Fixed the JOIN command to use the client entry's current
470 ID during the joining procedure instead of the one it sent
471 in the command (it is checked though), since it can change
472 between the packet processing and command processing, and
473 would just case unnecessary pain in the client end. Affected
474 file silcd/command.c.
476 * Fixed a channel key payload sending to use correct channel
477 ID when the server was forced to change the channel's ID by
478 router. Router sent the key payload with the old Channel ID.
479 Affected file silcd/packet_receive.c.
481 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
483 * Call silc_server_save_channel_key only if the key payload
484 was provided in the JOIN command's command reply. Affected
485 file silcd/command_reply.c.
487 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
489 * Fixed silc_mp_sizeinbase to return the value correctly with
490 MPI. Affected file lib/silcmath/mp_mpi.c.
492 * Fixed the stop_server signal to correctly stop the scheduler
493 and gracefully stop the server when SIGTERM or SIGINT signals
494 are received. Affected file silcd/silcd.c.
496 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
498 * Simple handling of TERM and HUP signals. Also added some log
499 flushing call around. Affected file is
502 * Fixed small bugs in silclog.c. Now buffering output will take
503 effect after 10 seconds since startup: This will ensure that
504 no important startup messages are lost. Also output redirection
505 will preserve original format ([Date] [Type] message).
506 Affected file is lib/silcutil/silclog.c.
508 * Added two options to the config file, in the logging section:
509 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
510 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
512 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
514 * Do not print the warning about log files not being initialized
515 more than once to avoid excess logging. Affected file is
516 lib/silcutil/silclog.c.
518 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
519 the SIM copying in make install in Makefile.am.pre.
521 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
523 * Rewritten silclog APIs. Globally interesting changes follows:
524 silc_log_set_files() changed to silc_log_set_file().
525 silc_log_set_callbacks() changed to silc_log_set_callback().
526 ROBOdoc documented silclog header file.
527 SilcLogCb now returns bool to wether inihibit the default
528 handler or not (to keep the old behaviour return always TRUE).
529 The new APIs should also fix the problem of the
530 silcd_error.log file that was written in the current directory.
533 Log files streams will remain opened after silc_log_set_file()
534 call, means less CPU usage notably on high traffic servers.
535 File streams are now full buffered, and flushed to the disk
536 every 5 minutes, lesses HD activity and CPU usage.
537 Messages can be redirected, allowing admins to configure
538 one single logfile for all server messages.
539 the silc_log_quick global variable to activate fast-logging.
540 Affected files lib/silcutil/silclog.[ch]
542 * Changed some code to conform new silclog APIs. Affected
543 files are doc/example_silcd.conf.in, silcd/server.c
544 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
547 * Fixed a memory leak that could occur in some situations.
548 Affected file silcd/serverconfig.c.
550 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
552 * Added the silc_client_del_client to remove the client from
553 all channels as well. Affected file lib/silcclient/idlist.c.
555 * Fixed the client library to correctly remove the client
556 from all channels when the client entry is being destroyed.
557 Affected file lib/silcclient/client_notify.c, command.c.
559 * Added auto-nicking support to the client library. If the
560 applicatio now sets client->nickname it will be sent to the
561 server after connecting by the library. This way for example
562 SILCNICK (or IRCNICK) environment variables will have effect
563 and always change the nickname automatically to whatever
564 it is wanted. Affected file lib/silcclient/client.[ch].
566 * Renamed silc_server_command_bad_chars to the
567 silc_server_name_bad_chars and moved it to the
568 silcd/server_util.[ch]. Added also new function
569 silc_server_name_modify_bad to return nickname that
570 includes bad characters as new nickname without those
571 bad characters. This check and modify is now used in
572 silc_server_new_client when the username is initially set
573 as nickname, so it must be checked to be valid nickname.
574 Affected file silcd/packet_receive.c.
576 * The nickname length is now taken from the packet for real
577 and not trusted to strlen() since it clearly can return
578 wrong length for nickname including bad characters. This
579 also applies to channel names. Affected file silcd/command.c.
581 * Removed the lib/silcsilm/modules directory. Modules are now
582 compiled into the lib/silcsim. Fixed the copying of the
583 modules to follow symbolic links in Makefile.am.pre.
585 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
587 * Fixed silc_string_regexify list creation. Fixes bugs with
588 BAN and INVITE commands in server. The affected file is
589 lib/silcutil/unix/silcunixutil.c.
591 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
593 * Removed the command destructor entirely from the server's
594 command and command reply routines. It is not needed, and
595 its usage was buggy and caused crashes. Affected files are
596 silcd/command[_reply].[ch].
598 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
600 * Cancel protocol and NULL sock->protocol if timeout
601 occurred during protocol. Affected file silcd/server.c.
603 * Cancel protocol timeouts always before calling the final
604 callback, to assure that after final callback is called
605 no other state will be called for the protocol anymore.
606 Affected file silcd/protocol.c.
608 * Print error log if incoming connection configuration could
609 not be found. Affected file silcd/server.c.
611 * Fixed JOIN command to correctly save the founder mode
612 to the client on normal SILC server, when the channel
613 was created by the router. Affected file silcd/command.c.
615 * Fixed LIST command (hopefully) to send correct reply
616 packets. Affected file silcd/command.c.
618 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
620 * The silc_packet_receive_process now returns FALSE if the
621 read data was invalid packet, and TRUE if it was ok.
623 The server now checks that if unauthenticated connection
624 sends data and its processing fails the server will close
625 the connection since it could be a malicious flooder.
627 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
629 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
631 * Make sure the warning about error opening a log file is
632 printed only once and not everytime it fails (produces
633 too much useless log). Affected file lib/silcutil/silclog.c.
635 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
637 * Made the silc_server_daemonise() function more readable.
638 Affected file silcd/server.c.
640 * Pid file is now optional, the user may comment it out from
641 the config file. Removed define SILC_SERVER_PID_FILE, we
642 don't need a default any longer. Affected file
643 configure.in.pre, lib/Makefile.am.pre.
645 * Make some use of the pid file. The server now dies at startup
646 if it detects a valid pid file on his path. The server would
647 die anyway in this circumstance, because of the bind() failure.
648 Affected file silcd/silcd.c.
650 * No longer compiling lib/dotconf.
652 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
654 * Fixed JOIN command parsing not to crash. Affected file
655 lib/silcclient/command.c.
657 * Fied the NICK_CHANGE notify to add the new client entry
658 even it is resolved. This removes an <[unknown]> nick
659 thingy bug in the client. Affected file is
660 lib/silcclient/client_notify.c.
662 * Do not try to allocate 0 bytes (efence does not like it)
663 in lib/silccore/silccomand.c when encoding payload.
665 * Do not take IRCNICK as nickname in Irssi SILC client since
666 it is not possible to set nickname before hand connecting
667 the server (TODO has an entry about adding auto-nicking
670 * Changed the silc_server_command_pending to check whether
671 there already exists an pending entry with the specified
672 command, command identifier and pending callback. This is
673 to fix IDENTIFY and WHOIS related crashes that may register
674 multiple pending commands with same identifier. Affected
675 file silcd/command.c.
677 * Fixed the server to reconnect to the router even if it
678 was already reconnecting and EOF was received. This to
679 fix a possibility that the server wouldn't ever try to
680 auto-reconnect to the router. Affected file silcd/server.c.
682 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
684 * Fixed the server's password authentication to use the
685 length of the locally saved password, and not the one
686 sent in the packet. Affected file silcd/protocol.c.
688 * Fixed same password authentication problem in the
689 Authentication Payload handling routines in
690 lib/silccore/silcauth.c.
692 * Yet another password authentication problem fixed with
693 channel password handling in silcd/command.c.
695 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
697 * If first character of string in silc_parse_userfqdn is '@'
698 then do not parse it. Affected file is
699 lib/silcutil/silcutil.c.
701 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
703 * Fixed minor bug in IDENTIFY command reply sending, which
704 caused various weird problems during JOIN when it was
705 resolving names for users. Affected file silcd/command.c.
707 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
709 * Fixed the IDENTIFY command reply sending to chech better valid
710 clients. It was possible to send incomplete list of replies.
711 Affected file silcd/command.c.
713 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
715 * Added silc_client_command[s]_[un]register functions now to
716 dynamically register the commands in client library. Removed
717 the static table of commands. This allows the client library
718 to call commands without causing the application to know about
719 what commands library has called.
721 Removed the INFO command reply kludge to detect when the command
722 was called by library. Now library use its own command reply
723 function for INFO command.
725 Added function silc_client_command_call to call a command.
726 Application can use it to call command, not access the structure
729 Now all commands that are sent by the client library (not
730 explicitly sent by application) use own command reply functions.
732 Affected files around lib/silcclient/ and in
733 irssi/src/silc/core/.
735 * Fixed the WHOIS command reply sending to chech better valid
736 clients. It was possible to send incomplete list of replies.
738 Fixed the WHOIS and IDENTIFY to send the request to router
739 if normal server did not do it and did not find any results.
741 Affected file silcd/command.c.
743 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
745 * Moved the internal data from SilcClient context into its
746 own file, not accesible to application. Affected files
747 lib/silcclient/client.h and lib/silcclient/client_internal.h,
748 and other files in client library.
750 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
752 * Added doc/examples installation target in Makefile.am.pre.
755 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
757 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
758 commands the found client entry will be removed from the
759 cache, after notifying application about the error. Affected
760 file lib/silcclient/command_reply.c.
762 * Changed the /MSG to check for exact nickname user gave, and
763 not let `nick' match `nick@host' if it is only one found. Now,
764 user must type the exact nickname (like nick@host2) even if
765 there are no more than one same nicks found. This is to avoid
766 a possibility of sending nickname to wrong nickname since
767 `nick' could match `nick@host'. Affected file is
768 irssi/src/core/silc-servers.c.
770 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
772 * Do not print "you are now server operator" or similar when
773 giving /away command. Affected files are
774 irssi/src/silc/core/client_ops.c, silc-servers.h.
776 * Made the silc_server_command_pending_error_check to send
777 the same command reply payload it received back to the
778 original sender of the command. This way all arguments
779 that was received by the server will be received by the
780 client too. Affected file silcd/command.c.
782 * Added the silc_idcache_add to return the created cache entry
783 to a pointer. Affected file lib/silccore/silcidcache.[ch].
785 * Add global clients to expire if they are not on any channel.
786 This is because normal server will never know if they signoff
787 if they are not on any channel. The cache expiry will take
788 case of these entries. This is done by normal servers only.
789 The affected files are silcd/command_reply.c,
790 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
792 * If server receives invalid ID notification for WHOIS or
793 IDENTIFY and the ID exists in the lists, it is removed.
794 Affected file silcd/command_reply.c.
796 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
797 in client then client entry that it matches is searched and
798 the nickname is printed on the screen for user. Affected
799 file irssi/src/silc/core/client_ops.c.
801 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
803 * Use cache entry expire time in the LIST command reply to
804 purge old entries from the cache after the LIST command
805 reply has been received. This way we don't have non-existent
806 entries in the cache for too long. Affected file is
807 silcd/command_reply.c.
809 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
811 * If we are normal server, and we've not resolved client info
812 in WHOIS or IDENTIFY from router, and it is global client,
813 we'll check whether it is on some channel. If it is not
814 then we cannot be sure about its validity and will resolve it
815 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
816 file silcd/command.c.
818 * Search channel by name (if possible) rather than by ID
819 in IDENTIFY command's command reply. Affected file is
820 silcd/command_reply.c.
822 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
824 * Distribute to the channel passphrase in CMODE_CHANGE notify.
825 Updated specs and implemented it. Affected file silcd/command.c,
826 silcd/packet_send.c and silcd/packet_receive.c.
828 * Implemented the <founder auth> payload handling in the JOIN
829 command. If provided all conditions for channel joining
830 except requirement to provide correct passphrase can be
831 overrided by the channel founder. Updated the protocol specs.
832 Affected file silcd/command.c.
834 Added support for founder auth in JOIN command in client
835 library. Fixed the parsing of the JOIN command now to support
836 all options as they should be. The affected file is
837 lib/silcclient/command.c.
839 * Optimized the WHOIS and IDENTIFY commands to send the request
840 to router only if it includes nicknames or other names. If
841 they include only IDs then check the local cache first before
842 routing. Affected file is silcd/command.c.
844 * Added channels topic announcements. Affected file is
845 silcd/packet_receive.c and silcd/server.c.
847 * Fixed the silc_server_send_notify_topic_set to really destine
848 the packet to channel. Affected file silcd/packet_send.c.
850 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
851 library. Affected file lib/silcclient/client_notify.c.
853 * Added UMODE announcements. Affected file silcd/server.c.
855 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
857 * Memory leak fixes in:
859 lib/silcutil/silcsockconn.c
860 lib/silcske/silcske.c
863 lib/silccrypt/silcpkcs.c
864 lib/silccore/silccommand.c
865 lib/silccore/silcidcache.c
870 * ROBOdoc documented the lib/silcske/groups.h file and a
871 bit changed the interface for better.
873 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
875 * Update the client entry context in the ID cache after
876 nick change. Affected file lib/silcclient/command.c.
877 Fixes the CUMODE command when regaining founder privileges,
878 and a little WHOIS problem.
880 * Fixed silc_net_gethostbyname to correctly call the
881 inet_ntop. Affected file lib/silcutil/silcnet.c.
883 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
885 * Added IPv6 support checking to the configure.in.pre, added
886 also --enable-ipv6 option to override the check. Affected
887 file configure.in.pre.
889 * The silc_thread_create now calls the start function
890 directly if threads support is not compiled in. Removes
891 ugly #ifdef's from generic code. Affected files are
892 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
894 * Added silc_net_gethostby[name/addr]_async to asynchronously
895 resolve. Affected files are lib/silcutil/silcnet.[ch].
897 * Added support for rendering IPv6 based server, client and
898 channel IDs. Affected file lib/silcutil/silcutil.c.
900 * Added support for creating IPv6 based server IDs. Affected
901 file is silcd/serverid.c.
903 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
905 * Added silc_net_gethostby[addr/name] into the
906 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
907 routines. Added silc_net_is_ip[4/6]. Affected file is
908 lib/silcutil/unix/silcunixnet.c. All routines that take
909 address as argument now supports both IPv4 and IPv6 addresses.
911 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
913 * Fixed LIST command reply sending in server. Affected file
916 * Server now sends the kicker's client ID in the KICK notify
917 to the kicked client. Affected file silcd/command.c.
919 * The client library now parses the kickers client ID and
920 UI displays it. Affected files lib/silcclient/client_notify.c
921 and irssi/src/silc/core/silc-channels.c, module-formats.c.
923 * Made all payload parsing function prototypes consistent.
924 They all take now const unsigned char * and uint32 pair as
925 the payload data instead of SilcBuffer. Changes all around
926 the source tree. Other unsigned char* -> const unsigned char*
927 changes around the tree as well.
929 * Optimized SFTP client and server packet sending not to
930 allocate new buffer for each packet but to recycle the
931 first allocated buffer. Affected files are
932 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
934 * Optimized the SFTP client to use SilcList instead of
935 SilcDList for requests, because it is faster. Affected file
936 is lib/silcsftp/sftp_client.c.
938 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
939 into lib/silccore/silcid.[ch].
941 Renamed silcpayload.[ch] into silcargument.[ch].
943 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
945 * If client entry is deleted with active key agreement
946 session, abort the session.
948 The silc_client_abort_key_agreement now calls the completion
949 callback with new SILC_KEY_AGREEMENT_ABORTED status.
951 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
954 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
956 * Don't use __restrict in older GCC's. Affected file is
957 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
959 * silc_net_localhost now attempts to reverse lookup the
960 IP/hostname. Affected file lib/silcutil/silcnet.c.
962 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
963 command. It can be used to gain founder privileges at
964 the same time when joining the channel.
966 Defined that the SILC_NOTIFY_TYPE_KICKED send the
967 kicker's client ID as well. Updated protocol specs.
969 Defined that the server must send SILC_COMMAND_IDENTIFY
970 command reply with error status to client who sent
971 private message with invalid client ID.
973 Updated the protocol specification.
975 * Added silc_server_send_command_reply to send any
976 command reply. Affected file silcd/packet_send.[ch].
978 * Added silc_id_payload_encode_data to encode ID payload
979 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
981 * The server now send IDENTIFY command reply with error
982 status if client ID in private message is invalid. Affected
983 file silcd/packet_receive.c.
985 * Save the server key file with server's IP address in
986 the filename instead of hostname. The affected file is
987 irssi/src/silc/core/client_ops.c.
989 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
991 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
994 * Added libtool support for compiling shared objects in
995 lib/silcsim. Affected file configure.in.pre and
996 lib/silcsim/Makefile.am. Original patch by cras.
998 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1000 * Pid file configuration, and server's config file fixes
1001 patch by toma. Updated CREDITS file.
1003 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1005 * Fixed silc_client_channel_message to not try to decrypt
1006 the message twice if it resolved the destination client
1007 information. This could cause of dropping one channel
1008 message. Affected file lib/silcclient/client_channel.c.
1010 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1012 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1013 lib/silcclient/client.c. This function is used when the SILC
1014 Client is run under some other scheduler, or event loop or
1015 main loop. On GUI applications, for example this may be
1016 desired to used to run the client under the GUI application's
1017 main loop. Typically the GUI application would register an
1018 idle task that calls this function multiple times in a second
1019 to quickly process the SILC specific data.
1021 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1023 * Fixed silc_server_drop() for dropping the supplementary
1024 groups as well, this could cause a security hole on some
1027 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1029 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1032 * Write PID file after dropping privileges. Added -F option
1033 to run server on foreground. A patch by debolaz.
1034 Affected files silcd/server.c, silcd/silcd.c.
1036 * Fixed MOTD to return the MOTD file server name. Affected
1037 file silcd/command.c.
1039 * Added INFO command reply handling to the Irssi SILC Client.
1040 Affected file irssi/src/silc/core/client_ops.c.
1042 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1044 * Fixed the silc_idcache_list_* routines to really support
1045 the dynamic list. Fixes a crash. Affected file is
1046 lib/silccore/silcidcache.c.
1048 * Fixed the LIST command reply to really call LIST command's
1049 pending callbacks. Affected file silcd/command_reply.c.
1051 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1053 * Update conn->local_entry->nickname after giving NICK
1054 command. Affected file lib/silcclient/command.c.
1056 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1058 * Added the [pid] option to the silcd configuration file
1060 Affected files: serverconfig.[ch] and silcd.c
1062 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1064 * Save fingerprint in WHOIS command reply in server.
1065 Affected file silcd/command_reply.c.
1067 * Fixed NICK commands pending callback registration.
1068 Affected file lib/silcclient/command.c.
1070 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1072 * Use ++server->cmd_ident when sending commands in server,
1073 instead of random number. Affected file silcd/command.c.
1075 * Fixed GETKEY command reply to call actually GETKEY pending
1076 command callbacks. Affected file silcd/command_reply.c.
1078 * A bit stricter check for nicknames. Check for same nickname
1079 in NICK command also. Affected file silcd/command.c.
1081 * Do not call INFO command everytime client ID changes, only
1082 during first connecting. Affected file lib/silcclient/client.c.
1084 * Set the new nickname only after successful command reply for
1085 NICK command is returned by server. Affected file
1086 lib/silcclient/command.c.
1088 * Remove nicknames from nicklist during server_signoff notify.
1089 Should fix /NAMES bit more. The affected file is
1090 irssi/src/silc/core/silc-channels.c.
1092 * Added `fingerprint' field to the SilcIDListData in the
1093 silcd/idlist.h to hold the fingerprint of the client's
1096 Send the fingerprint of the client's public key in WHOIS
1099 Affected files silcd/command.c, and silcd/idlist.[ch].
1101 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1102 create fingerprint from given data.
1104 * Show the fingerprint of the client's public key in WHOIS.
1105 Affected files irssi/src/module-formats.[ch] and
1106 irssi/src/silc/core/client_ops.c.
1108 * Format the multiple same nicknames also during JOIN and
1109 NICK_CHANGE notifys. Affected file is
1110 lib/silcclient/client_notify.c.
1112 * Do not print error on screen for invalid private message
1113 payload since it can come if someone is sending private
1114 messages with wrong key. Affected file
1115 lib/silccore/silcprivate.c.
1117 * Fixed multiple concurrent /PING crash. Affected file
1118 lib/silcclient/command.c.
1120 * Changed the wrong ID encoding. All IP addresses must be
1121 in MSB first order in encoded format. They were encoded
1122 wrong and was in LSB format. Affected files are
1123 silcd/serverid.c, lib/silcutil/silcutil.c.
1125 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1127 * Call the `connect' client operation through the scheduler
1128 in case of error. Affected file lib/silcclient/client.c.
1130 * Call the `failure' client operation even if the error
1131 occurred locally during a protocol. Affected file is
1132 lib/silcclient/protocol.c.
1134 * Added support of sending LIST command to router from normal
1135 server. This way normal server can get list of all channels
1136 in the network too. Fixed the channel list sending in the
1137 server too. Affected files are silcd/command.c, and
1138 silcd/command_reply.[ch].
1140 * Added silc_server_update_channels_by_server and
1141 silc_server_remove_channels_by_server. They are used during
1142 disconnection of primary router and in backup router protocol.
1143 Affected file silcd/server_util.[ch], silcd/server.c and
1144 silcd/server_backup.c.
1146 * Fixed channel adding to global list in IDENTIFY command
1147 reply in server. Affected file silcd/command_reply.c.
1149 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1151 * If the incoming packet type is REKEY or REKEY_DONE process
1152 that packet always synchronously. Fixes yet another MAC
1153 failed error on slow (dialup) connections. Affected file
1154 lib/silcclient/client.c and silcd/server.c.
1156 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1158 * Call check_version SKE callback for initiator too. Affected
1159 file lib/silcske/silcske.c.
1161 * Implemented fix for security hole found in the SKE that was
1162 fixed in the specification few days back; the initiator's
1163 public key is now added to the HASH value computation.
1164 Added backwards support for the old way of doing it too, for
1165 old clients and old servers. Affected file is
1166 lib/silcske/silcske.c.
1168 * Enabled mutual authentication by default in SKE. If initiator
1169 is not providing mutual authentication the responder will
1170 force it. This will provide the proof of posession of the
1171 private key for responder. The affected files are
1172 lib/silcclient/protocol.c and silcd/protocol.c.
1174 * Do not cache anymore the server's public key during SKE.
1175 We do mutual authentication so the proof of posession of
1176 private key is done, and if the server is authenticated in
1177 conn auth protocol with public key we must have the public
1178 key already. Affected file silcd/protocol.c.
1180 * Added new global debug variable: silc_debug_hexdump. If
1181 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1182 file lib/silcutil/silclog.[ch].
1184 * Fixed compilation warning due to char * -> const char *.
1185 Affected files lib/silcutil/silcnet.h, and
1186 lib/silccore/silcauth.[ch].
1188 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1190 * Fixed CMODE command when new channel key was created. If
1191 the creation failed the old key was removed. Next time giving
1192 same command would crash the server since the old key was
1193 freed already. Affected file silcd/command.c.
1195 * Fixed the silc_server_announce_get_channels to not crash
1196 on reconnect. Affected file silcd/server.c.
1198 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1200 * Added silc_log_set_debug_string function to set a regex
1201 string to match for debug output. Only the function names,
1202 or filenames matching the given debug string is actually
1203 printed. This way it is possible to filter out those debug
1204 strings that user is not interested in.
1206 Fixed a bug in silc_string_regexify.
1208 Affected files lib/silcutil/silclog.[ch], and
1209 lib/silcutil/unix/silcunixutil.c.
1211 * Changed the -d options in both server and Irssi SILC client
1212 to take the debug string as argument. Affected files
1213 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1215 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1217 * Added silc_hash_babbleprint to create a Bubble Babble
1218 Encoded fingerprint. The encoding is developed by Antti
1219 Huima (draft-huima-babble-01.txt), and it creates human
1220 readable strings out of binary data. Affected file
1221 lib/silccrypt/silchash.[ch].
1223 * Print the babble print now in addition of fingerprint as well
1224 in Irssi SILC client. Affected files are
1225 irssi/src/fe-common/silc/module-formats.[ch],
1226 irssi/src/fe-common/silc/core/client_ops.c.
1228 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1230 * Fixed a security problem found in SKE. The initiator's
1231 public key too is now added to the HASH hash value creation
1232 which is signed by the responder to create the SIGN value.
1233 This will prevent anyone in the middle to lie to the responder
1234 about the initiator's public key. If this is done now, the
1235 man in the middle will get caught. Updated the protocol
1238 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1240 * Better installation directory handling. Configure module
1241 paths and other paths automatically to example_silc* files
1242 in doc/. A patch by toma.
1244 * Fixed compiler warning from MPI library, and from SILC RNG.
1247 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1248 It can be configured with ./configure. A patch by toma.
1250 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1252 * Find correct make to use in prepare-clean. A patch by
1253 toma. Affected file prepare-clean.
1255 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1257 * Added irssi variables use_auto_addr, auto_bind_ip,
1258 auto_bind_port and auto_public_ip.
1260 * Changed the interface for silc_client_send_key_agreement
1261 in lib/silcclient/silcapi.h
1265 irssi/src/silc/core/silc-core.c
1267 lib/silcclient/silcapi.h
1268 irssi/src/silc/core/silc-channels.c
1269 lib/silcclient/client_keyagr.c
1272 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1274 * Added silc_pkcs_public_key_compare to compare two
1275 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1277 * Check that the client who set the founder mode on the
1278 channel is the same client that is giving the founder
1279 mode to itself. It is done by comparing the saved public
1280 key (it is saved even in the authentication is passphrase).
1281 Affected file silcd/command.c.
1283 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1285 * Do not process packet for disconnected socket connection.
1286 Affected file lib/silccore/silcpacket.c.
1288 * Process the DISCONNECT packet through scheduler in the
1289 client library. Affected file lib/silcclient/client.c.
1291 * Fixed the silc_client_packet_parse to not to increase
1292 the packet sequence number if the conn->sock and the
1293 current socket connection is not same. This can happen
1294 for example during key agreement when the conn includes
1295 multiple socket connections (listeners). Affected file
1296 lib/silcclient/client.c.
1298 * The sender of the file transfer request now provides also
1299 the pointer (listener) for the key exchange protocol. If
1300 the listener cannot be created then it sends empty key
1301 agreement and lets the receiver provide the listener.
1303 Added `local_ip' and `local_port' arguments to the
1304 silc_client_file_send. If they are provided they are used,
1305 if not then it will attempt to find local IP address, if
1306 not found or bind fails then the remote client will provide
1309 Affected files are lib/silcclient/client_ftp.c and
1310 lib/silcclient/silcapi.h.
1312 * Extended the FILE SEND command to support defining the
1313 local IP and port for key exchange listener. They are
1314 optional. Affected file irssi/src/silc/core/silc-servers.c.
1316 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1318 * Defined to WHOIS command reply the sending of fingerprint
1319 of the client's public key (if the proof of posession of the
1320 corresponding private key is verified by the server).
1321 Updated to the protocol specification.
1323 * Added support of receiving the client's public key's
1324 fingerprint in command reply in client library. Affected
1325 file is lib/silcclient/command_reply.c, and
1326 lib/silcclient/idlist.[ch].
1328 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1330 * Do not send over 128 chars long nickname to the server
1331 in NICK command. Affected file lib/silcclient/command.c.
1333 * Do not send over 256 chars long channel names to the server
1334 in JOIN command. Affected file lib/silcclient/command.c.
1336 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1338 * Assure that silc_server_close_connection cannot be called
1339 twice for same socket context. Affected file is
1342 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1344 * Send error message to application if opening file for
1345 writing during file transfer fails. Affected file is
1346 lib/silcclient/client_ftp.c.
1348 Remove all file transfer sessions for a client that we're
1349 removing from ID cache.
1351 Affected file is lib/silcclient/client_ftp.c.
1353 * Fixed silc_net_addr2bin to return correct address. Affected
1354 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1356 * Fixed file transfer session removing on signoff notify.
1357 Affected file irssi/src/silc/core/silc-servers.c.
1359 * Added the SilcClientFileError to be returned in the monitor
1360 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1361 Affected file lib/silcclient/silcapi.h.
1363 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1365 * Fixed a crash in silc_client_ftp_free_sessions and
1366 silc_client_ftp_session_free_client. Affected file
1367 lib/silcclient/client_ftp.c.
1369 * Added `disabled' field in the SilcChannelEntry in the server
1370 to indicate if the server entry is disabled. Affected file
1371 silcd/idlist.h, silcd/command[_reply].c.
1373 * SILC server adds now /var/run/silcd.pid everytime it is
1374 started. Affected file silcd/silcd.c.
1376 * Added silc_server_packet_send_clients to send a packet to
1377 the provided table of client entries. Affected file
1378 silcd/packet_send.[ch].
1380 * Fixed a crash in client resolving in client_prvmsg.c in
1381 client library. Affected file lib/silcclient/client_prvmsg.c.
1383 * Do not actually remove the client directly from ID cache
1384 during SERVER_SIGNOFF, but invalidate it. This way we
1385 preserve the WHOWAS info for the client. Affected file
1386 silcd/server_util.c.
1388 * Fixed SERVER_SIGNOFF notify handling in the server. The
1389 server is now able to process incoming SERVER_SIGNOFF notify
1390 for a server that it doesn't even know about. It will remove
1391 the clients provided in the notify. Affected file
1392 silcd/packet_receive.c.
1394 * Check for partial packet in data queue after every packet that
1395 was found from the queue. Return and wait for more data if
1396 there is partial data in queue. Affected file is
1397 lib/silccore/silcpacket.c.
1399 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1401 * Added SilcClietFileError enum to indicate error in
1402 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1403 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1404 Affected files lib/silcclient/silcapi.h and
1405 lib/silcclient/client_ftp.c.
1407 * Check that newsize in silc_buffer_realloc is larger than
1408 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1410 * Added better monitor of file transfers. It now monitors
1411 key agreement protocol during the file transfer too. Added
1412 error reporting too. Affected files
1413 irssi/src/silc/core/silc-servers.c,
1414 irssi/src/fe-common/silc/module-formats.[ch].
1416 * Wrote a help file for FILE command.
1418 * Added silc_rng_global_get_byte_fast to get not-so-secure
1419 random data as fast as possible. Random data is read from
1420 /dev/urandom if available and from the SILC RNG if not
1421 available. It is used in padding generation. Affected file
1422 lib/silccrypt/silcrng.[ch].
1424 * All packets in client library are now processed synchronously.
1425 Optimized packet processing a lot. Affected file
1426 lib/silcclient/client.c.
1428 * All server connection packets are processing synchronously
1429 now in server, to optimize packet processing. Affected file
1432 * Include files are installed now only in Toolkit distribution
1433 if make install is given. Affected files: all Makefile.am's.
1435 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1437 * Assure that silc_client_notify_by_server_resolve does not
1438 resolve the client information multiple times. If it cannot
1439 be found by the first it cannot be found at all. Affected
1440 file lib/silcclient/client_notify.c.
1442 * Fixed WHOWAS command reply calling. Affected file
1443 lib/silcclient/command_reply.c.
1445 * Removed all references to silc_idlist_get_client from the
1446 Irssi SILC client since that call is internal call used by
1447 the library. The Irssi SILC client will use now client
1448 retrieval functions found in silcapi.h.
1450 * Fixed a bug in resolving nickname info before sending
1451 private message. It used freed memory. Affected file
1452 irssi/src/silc/core/silc-servers.c.
1454 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1456 * Assure my_channels statistics cannot go negative in server.
1457 Affected files silcd/server.c, silcd/server_util.c.
1459 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1461 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1463 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1465 * Win32 Toolkit changes. Affected files

1467 win32/libsilcclient/libsilc.def,
1468 lib/silcutil/silcutil.c, and
1469 lib/sftp/sftp_fs_memory.c.
1471 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1473 * Added silc_net_localip to return local host's IP address.
1474 Affected file lib/silcutil/silcnet.[ch].
1476 * If key exchange or rekey protocol is active for a connection
1477 parse all packets syncronously since there might be packets
1478 in packet queue that we are not able to process without first
1479 processing packets before them. Affected file silcd/server,
1480 lib/silcclient/client.c.
1482 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1483 whether library should continue processing the packet.
1484 Affected file lib/silccore/silcpacket.h.
1486 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1487 SilcSFTPMonitorData to SFTP server to monitor various
1488 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1489 lib/silcsftp/sftp_server.c.
1491 * Added silc_file_size to return file size. Affected file
1492 lib/silcutil/silcutil.[ch].
1494 * Implemented the file transfer support for the client library.
1495 Added preliminary support for simple client to client one-file
1496 transmission. Affected file lib/silcclient/client_ftp.c,
1497 lib/silccilent/client.[ch].
1499 * Added new local command FILE to the Irssi SILC Client.
1500 It is used to perform the file transfer. It has subcommands
1501 SEND, RECEIVE, SHOW and CLOSE. Affected files
1502 irssi/src/silc/core/client_ops.c,
1503 irssi/src/silc/core/silc-server.[ch].

1512 * Renamed silc_file_read and silc_file_write to functions
1513 silc_file_readfile and silc_file_writefile. Added function
1514 silc_file_open and silc_file_close. Affected files
1515 lib/silcutil/silcutil.[ch].
1517 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1519 * Resolve the client info when received private message or
1520 channel message for a client which nickname we don't know.
1521 Affected files lib/silcclient/client_prvmsg.c and
1522 lib/silcclient/client_channel.c.
1524 * Do not crash in /KEY if client is not connected. Affected
1525 file irssi/src/silc/core/silc-channels.c.
1527 * Added SilcClientStatus field to the SilcClientEntry in the
1528 lib/silcclient/idlist.h.
1530 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1531 is incomplete and is being resolved, it won't be resolved
1534 Make sure also that USERS command reply does not resolve
1535 twice information. Affected file is
1536 lib/silcclient/command_reply.c.
1538 Make sure that silc_client_get_clients_by_list does not
1539 resolve twice same information.
1541 * Check for valid client->id in the silc_server_free_client_data.
1542 Affected file silcd/server.c.
1544 * Fixed /GETKEY nick@server not to crash if the server entry
1545 is not found. Affected file lib/silcclient/command.c.
1547 * Fixed the silc_server_check_cmode_rights to check the
1548 requested modes correctly. Affected file silcd/command.c.
1550 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1552 * Better checks for non-printable chars in nick added.
1553 Affected file silcd/command.c.
1555 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1557 * Call the silc_server_udpate_servers_by_server in the
1558 primary router that comes back online in the backup resuming
1559 protocol. Otherwise it routes packets wrong. Affected file
1560 silcd/server_util.[ch], silcd/server_backup.c.
1562 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1564 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1565 lib/silcutil/silcbuffmt.[ch].
1567 * Redefined the SILC packet header to include the padding
1568 length. Affected file lib/silccore/silcpacket.[ch].
1570 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1571 length for maximum padding up to 128 bytes). Affected
1572 file lib/silccore/silcpacket.h.
1574 * Removed all backwards support for old 0.5.x MAC thingies.
1575 The SILC packet header change makes it impossible to be
1576 backwards compatible.
1578 * Send the ENDING packet with timeout in the backup resuming
1579 protocol. This is to assure that all routers has connected
1580 to the primary router. Affected file silcd/server_backup.c.
1582 * Changed the RNG to take the first IV from random data. It
1583 used to take it from zero actually. Changed the RNG also
1584 to use /dev/urandom during session. /dev/random is used
1585 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1587 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1589 * Changed the SILC packet header to have the first two bytes
1590 (the packet length) encrypted. Affected files aroung the
1591 code tree, lib/silccore/silcpacket.[ch]. Removed the
1592 SilcPacketCheckDecrypt callback. It is not needed anymore
1593 since the silc_packet_receive_process will determine now
1594 whether the packet is normal or special.
1596 * Implemented the unidirectional MAC keys. Affected files
1597 lib/silcske/silcske.c, silcd/protocol.c and
1598 lib/silcclient/protocol.c.
1600 * Implemented the packet sequence number to the MAC computation.
1601 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1602 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1603 lib/silcclient/protocol.c.
1605 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1607 * Allow backup router to announce servers. All servers
1608 announced by backup router are added to the global list
1609 automatically. Update hte server's socket to our primary
1610 router also when backup router announces a server.
1611 Affected file silcd/packet_receive.c.
1613 * Do not update the client->router in the function
1614 silc_server_udpate_clients_by_server if the client is on
1615 global list. We might fail to find any specific server
1616 for locally connected clients and local cell clients. They
1617 should still use the `from' and not `to' as client->router.
1618 This fixes backup router resuming protocol. Affected file
1619 silcd/server_util.c.
1621 * Decrease channel statistics count only if the channel
1622 deletion worked. Affected files are silcd/server.c and
1623 silcd/server_util.c.
1625 * Added silc_server_update_servers_by_server to update origin
1626 of all server entries. Used during backup router protocol.
1627 Affected files silcd/server_util.[ch], silcd/server.c. and
1628 silcd/backup_router.c.
1630 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1631 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1632 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1633 lib/silccrypt/silchmac.c.
1635 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1637 * Assure that router cannot reroute the same channel message
1638 to the sender. Affected file silcd/packet_receive.c.
1640 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1642 * Made better checks that the channel message is not sent
1643 to the router it came from. Affected file is
1644 silcd/packet_send.c. Fixed memory leak too.
1646 * Announce informations for incoming router connection, but
1647 only after checking if it is replaced by backup router.
1648 Affected file silcd/packet_receive.c.
1650 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1652 * Fixed the backup resuming protocol to work in multiple
1653 router environment. Affected file silcd/server_backup.c.
1655 * Route packet only to one router in the function
1656 silc_server_packet_send_to_channel. Affected file is
1657 silcd/packet_send.c.
1659 * Fixed silc_server_send_notify_dest to set the broadcast
1660 flag. Fixed the silc_server_send_notify_topic to actually
1661 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1662 Affected file silcd/packet_send.c.
1664 * Changed the SFTP Filesystem interface. Changed the
1665 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1666 the filesystem operation function. The SilcSFTPFilesystem
1667 is now a context that is allocated by all filesystem allocation
1668 functions and it already includes the operations structure
1669 and filesystem specific context. It is given as argument
1670 now to the silc_sftp_server_start. This made the interface
1671 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1672 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1674 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1676 * Changed the backup router adding and getting interfaces
1677 in the server. The router that will be replaced by the
1678 specified backup router is now sent as argument. Affected
1679 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1682 * Added silc_net_addr2bin_ne to return the binary form of
1683 the IP address in network byte order. Affected files
1684 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1686 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1688 * Check for existing server ID in silc_server_new_server
1689 and in silc_server_connect_to_router_final and remove the
1690 old entry if it exists. Affected file silcd/packet_receive.c,
1693 * Send the channel message always to only one router, either
1694 in upstream or downstream. Affected file is
1695 silcd/packet_send.c.
1697 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1699 * Wrote the definition of the backup resuming protocol to the
1700 protocol specification.
1702 * Removed one redundant channel key generation from normal
1703 server during joining procedure. Removed one redundant
1704 channel key sending from server to router during joining
1705 procedure. Affected file silcd/command.c.
1707 * Made minor bugfixes to the backup router resuming protocol.
1708 Affected file silcd/server_backup.c, server.c.
1710 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1712 * Added --disable-asm configuration option. Affected files
1713 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1716 * Implemented the backup resuming protocol that is used to
1717 resume the primary router position in the cell after the
1718 primary router comes back online. Affected files
1719 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1720 and silcd/server_util.[ch].
1722 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1724 * Sleep two (2) seconds after sending QUIT command to server.
1725 Affected file lib/silcclient/command.c.
1727 * Assure that if outgoing data buffer is pending do not force
1728 send any data. Affected file silcd/packet_send.c.
1730 * Assure that if outgoing data buffer is pending do not force
1731 send any data. Affected file lib/silcclient/client.c.
1733 * Implemented the backup router support when the primary router
1734 goes down. The servers and routers can now use the backup
1735 router as new primary router without loosing connectivity.
1737 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1739 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1740 in the server to indicate disabled entry. All data read
1741 from the connection will be ignored and no data is sent
1742 for entry that is disabled. Affected files are
1743 silcd/idlist.h, silcd/server.c.
1745 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1747 * Created SFTP client and server test programs in the
1748 lib/silcsftp/tests directory.
1750 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1752 * Implemented memory filesystem (virtual filesystem) for
1753 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1756 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1758 * Implemented the SFTP (SSH File Transfer Protocol) to the
1759 lib/silcsftp. It includes SFTP client and SFTP server
1762 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1764 * Moved lib/silccore/silcprotocol.[ch] to the
1765 lib/silcutil library.
1767 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1768 take variable argument list pointer as argument. Affected
1769 file lib/silcutil/silcbuffmt.[ch].
1771 * Added silc_buffer_set function that is used to set data
1772 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1773 Affected file lib/silcutil/silcbuffer.h.
1775 * Changed various routines in the core library to use the new
1776 silc_buffer_set instead of allocating new buffer only for
1779 * Added 64-bit value formatting and unformatting support to the
1780 silc_buffer_[un]format routines. Affected file is
1781 lib/silcutil/silcbuffmt.[ch].
1783 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1784 to includes/bitmove.h.
1786 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1788 * Fixed channel user mode saving in client library. Affected
1789 file lib/silcclient/command[_reply].c.
1791 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1793 * Defined the file transfer to the SILC Protocol. Added
1794 new packet type SILC_PACKET_FTP and defined File Transfer
1795 Payload. The mandatory file transfer protocol is SFTP
1796 (SSH File Transfer Protocol). Affected file in addition
1797 of the internet draft is lib/silccore/silcpacket.h.
1799 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1800 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1801 is used as part of backup router protocol when the primary
1802 router of the cell is back online and wishes to resume
1803 the position as primary router.
1805 * Redefined the MAC generation keys in the protocol. The
1806 same key is not used anymore in both direction. Both
1807 direction will now use different keys for sending and
1808 receiving. This fixes a potential security flaw. This
1809 change causes incompatibilities in the protocol.
1811 * Redefined also the MAC computation from the packet.
1812 An packet sequence number is now added to the MAC
1813 computation. This prevents possible replay attacks against
1814 the protocol. This change too causes incompatibilities
1817 Added `sequence' field to the SilcPacketContext to hold
1818 the current sequence number for the packet.
1820 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1822 * Added `created' field to the SilcIDListData in the file
1823 silcd/idlist.h to indicate the time when the entry was
1826 * Added `created' field to the SilcChannelEntry too. Affected
1827 file silcd/idlist.h.
1829 * Added `creation_time' aguments to all the announcement functions
1830 in the server. If it is provided then only the entries that
1831 was created after the provided time frame are actually
1832 announced. Affected file silcd/server.[ch].
1834 * The protocol says that the Channel ID's IP address must be
1835 based on the router's IP address. Added check for this in
1836 the silc_server_new_channel when processing incoming New Channel
1837 Payload. Affected file silcd/packet_receive.c.
1839 * Print out the correct version with --version in SILC client.
1840 Affected file irssi/src/silc/core/silc-core.c.
1842 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1844 * Fixed WHOWAS command to check for completnes of the client
1845 entry always, not just when the command is coming from client.
1846 Affected file silcd/command.c.
1848 * Added new function silc_server_packet_queue_purge to purge the
1849 outgoing data queue to the network. After the function returns
1850 it is guaranteed that the outgoing packet queue is empty.
1851 Affected file silcd/packet_send.[ch].
1853 * Purge the outgoing packet queue in the rekey protocol's final
1854 callback to assure that all rekey packets go to the network
1855 before quitting the protocol. Affected file silcd/server.c.
1857 * Added silc_client_packet_queue_parse as similar function as
1858 in server to the client library. The affected file is
1859 lib/silcclient/client.c.
1861 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1863 * Splitted silcd/server.c and created silcd/server_util.[ch]
1864 for utility functions.
1866 * Added new socket flag SILC_SF_DISABLED to indicate that the
1867 connection is open but nothing can be sent to or received from
1868 the connection. Affected file lib/silcutil/silsockconn.[ch].
1869 The checking for disabled socket is checked in the low level
1870 silc_socket_write and silc_socket_read functions.
1872 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * Allow only nicknames and channel names that fits into the
1875 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1877 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1879 * When processing JOIN command reply in server check that if
1880 the channel exists in our global list we'll move it the local
1881 list. Affected file silcd/command_reply.c.
1883 * Fixed the check whether client is joined on the channel already
1884 in JOIN command. Affected file lib/silcclient/command.c.
1886 * Fixed the JOIN command reply to check whether the channel
1887 already exists. Affected file lib/silcclient/command_reply.c.
1889 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1891 * Added silc_ske_status_string to map the SKE error numbers
1892 to readable strings. The affected files are
1893 lib/silcske/silcske[_status].[ch].
1895 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1897 * Do not show the private channels on the WHOIS channel list
1898 as it is not allowed by the protocol. The affected file is
1901 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1903 * Assure that the packet length digged from the actual packet
1904 is something sensible in the silc_packet_decrypt_rest_special
1905 in lib/silccrypt/silcpacket.c.
1907 * Free and NULL the allocated pointer in silc_hmac_alloc if
1908 the HMAC allocation fails. The affected file is
1909 lib/silccrypt/silchmac.c.
1911 * Print the selected security properties to the log files in
1912 the server. Affected file silcd/protocol.c.
1914 * Add SKE's reference counter even if calling the completion
1915 callback manually. Otherwise it goes negative, although it
1916 does not cause any problems. The affected file is
1917 lib/silcske/silcske.c.
1919 * Remove the client entry with short timeout after giving the
1920 KILL command. Affected file lib/silcclient/command.c.
1922 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1923 case all found clients are already disconnected (WHOWAS would
1924 found them) in the server. Affected file silcd/command.c.
1926 * Update the last_receive (time of last data received) to be
1927 updated only when received private or channel message so that
1928 the idle time showed in WHOIS makes more sense.
1930 * Added boolean field `valid' in to the SilcClientEntry in the
1931 client library to indicate whether the entry is valid or not.
1932 This fixes the nickname change bug on channel when changing
1933 the nickname to be same than the old (like nick to Nick) the
1934 nickname formatter doesn't set the new nick anymore to Nick@host.
1935 Affected file lib/silcclient/idlist.[ch].
1937 * Now actually fixed the nickname changing on disconnection.
1938 Added new function silc_change_nick to the Irssi SILC Client.
1939 Affected file irssi/src/silc/core/client_ops.c,
1940 irssi/src/silc/core/silc-nicklist.[ch].
1942 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1944 * Check that the public key exists in the GETKEY command before
1945 trying to encode it. Affected file silcd/command.c.
1947 * Print some notifications on received public keys with GETKEY
1948 command in the Irssi SILC Client. Affected files are
1949 irssi/src/fe-common/silc/module-formats.[ch],
1950 irssi/src/silc/core/client_ops.c.
1952 * Use IDENTIFY command to resolve the server information in the
1953 GETKEY command instead of INFO command. Affected file
1954 lib/silcclient/command.c.
1956 * All command reply functions in the client library now calls
1957 the pending command reply callbacks even if an error has
1958 occurred. The server has done this a long time and now it was
1959 time to move the client library to this as well. Now all
1960 errors can be delivered back to the pending command reply
1961 callbacks if necessary. Affected files are
1962 lib/silcclient/command[_reply].[ch].
1964 * Change the nickname on disconnection back to the username
1965 because in reconnect the server will enforce it to it anyway.
1966 Affected file irssi/src/silc/core/silc-servers.c.
1968 * Fixed a config file parsing bug in the Irssi SILC client.
1969 Affected file irssi/src/silc/core/clientconfig.c.
1971 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * When printing the channel mode on JOIN, verify that the
1974 channel key and channel's HMAC are valid. Affected file
1975 irssi/src/silc/core/client_ops.c.
1977 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1979 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1980 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1981 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1983 * Removed channel key rekey task deleting from the function
1984 silc_server_save_channel_key. Affected file silcd/server.c.
1985 Added explicit timeout task context instead that is used to
1986 delete the task if we are registering a new task before the
1987 new task has elapsed.
1989 * When channel key rekey occurs the client library now saves
1990 the old channel key for a short period of time (10 seconds) and
1991 is able to use it in case some is still sending channel
1992 messages encrypted with the old key after the rekey. Affected
1993 file lib/silcclient/[idlist.h|client_channel.c].
1995 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1997 * Added check to the silc_server_new_id_real to not accept
1998 new ID if it is the sender's own ID. Affected file is
1999 silcd/packet_receive.c.
2001 * Assure that we do not announce ourself or the one we've
2002 sending our announcements when we're router and are announcing
2003 servers to our primary router. Affected file silcd/server.c.
2005 * Fixed silc_server_command_identify_check_client to assemble
2006 correct WHOIS packet. It send corrupted WHOIS packet and
2007 caused problem with router to router connections. Affected
2008 file silcd/command.c.
2010 Fixed also silc_server_command_whois_check the same way
2011 as for the IDENTIFY command.
2013 * Added new SilcIDListStatus to the server in the SilcIDListData
2014 structure. The status now includes the current status of
2015 the entry (like registered, resolved etc.). Affected file
2016 silcd/idlist.[ch]. Defined a bunch of different status types
2017 as well. This replaced the old boolean registered field as well.
2019 Added resolve_cmd_ident field to the SilcClientEntry structure
2020 too so that if the entry is for example being resolved so
2021 another command may attach to the same pending command reply
2022 without requiring to resolve the same entry again. This concept
2023 should optimize the WHOIS and the IDENTIFY resolving under
2024 heavy load by taking away unnecessary resolving for entries
2025 that are being resolved already.
2027 Added support for adding multiple pending commands for one
2028 command idenfier. Affected file silcd/command[_reply].[ch].
2030 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2031 before deleting the data. Otherwise the hash table will have
2032 freed data in comparison functions. Affected file is
2033 silcd/command_reply.c.
2035 * Fixed silc_idlist_replace_client_id to add the new entry to
2036 the cache with NULL nickname. Otherwise there will be invalid
2037 memory as the nickname after the nickname is freed. Affected
2038 file silcd/packet_receive.c.
2040 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2041 saved into wrong slots because the previous number of entries
2042 was not taken into account. Affected file silcd/idlist.c.
2043 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2045 * If we are router and we receive JOIN notify to a channel that
2046 does not have any users then notified client is marked as the
2047 channel founder, as it is it. The affected file is
2048 silcd/packet_receive.c
2050 * Added to the extended hash table API's table_del_*ext functions
2051 the destructor as argument too, so that the caller can decide
2052 which destructor to use or whether to use destructor at all.
2053 Affected file lib/silcutil/silchashtable.[ch].
2055 * Fixed ID Cache purging. It actually deleted the entries from
2056 the hash table after the data was freed. The hash table ended
2057 up comparing freed memory. The affected file is
2058 lib/silccore/silcidcache.c.
2060 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2062 * Fixed Irssi SILC client's KILL command's HELP syntax.
2064 * The USERS command now resolves the detailed user information
2065 if the userinfo field is missing. Affected file is
2066 lib/silcclient/command_reply.c.
2068 * Do not print error in silc_file_read if the read file does
2069 not exist. Just silently return NULL. Affected file is
2070 lib/silcutil/silcutil.c.
2072 * Fixed the silc_log_output to not wine about NULL filename
2073 and to not create some bogus " " filename. Affected file is
2074 lib/silcutil/silclog.c.
2076 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2078 * Fixed various printing bugs on the user interface in the
2079 Irssi SILC Client. Minor changes that were forgotten from
2082 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2084 * Fixed the configure.in.pre and the compilation and distribution
2085 environment to support the new autoconf 2.52. That version is
2086 now required to compile the CVS trunk.
2088 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2090 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2091 to generally parse user@fqdn format strings. Affected file
2092 lib/silcutil/silcutil.c.
2094 * Added nickname_format and nickname_force_format fields to the
2095 SilcClientParams structure. The first one defines the format
2096 for the nicknames that the library will enforce if the receives
2097 multiple same nicknames. The second one is boolean value and
2098 can be used to force the library to always enforce the format
2099 to the nicknames regardles whether there are multiple nicknames
2100 or not. This configurable formatting was employed to flexibly
2101 support accessing multiple nicknames from the user interface.
2102 The userinterface can now set the nicknames to what ever format
2103 they prefer. Affected file lib/silcclient/silcapi.h.
2105 Added function silc_client_nickname_format to the file
2106 lib/silcclient/idlist.c. It performs the nickname formatting.
2108 Added new field `hostname´ to the SilcClientEntry context.
2109 It holds the hostname of the client. Affected file is
2110 lib/silcclient/idlist.h.
2112 * Irssi SILC Client sets the nicknames in nick@hostn format.
2113 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2114 irssi/src/silc/core/silc-core.c.
2116 The WHOIS printing now also shows both the real nickname and
2117 the formatted nickname so that user knows how to access the
2118 user if there are multiple same nicknames cached. Affected
2119 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2120 printing formatting too to take the hostname now as a separate
2121 argument. The Affected file is
2122 irssi/src/fe-common/silc/modules-formats.[ch].
2124 * Changed the silc_client_get_clients_local to accept the formatted
2125 nickname as argument. It accepts the real nickname too but the
2126 formatted nickname can be used to find the true entry from
2127 multiple entries. Affected file lib/silcclient/silcapi.h and
2128 lib/silcclient/idlist.c.
2130 * Added nickname_format_parse field to the SilcClientParams.
2131 It is a callback function provided by the application to parse
2132 the nickname out of the formatted nickname string. The library
2133 calls it to get the nickname from the formatted string. Since
2134 the application generally knows better the format of the nickname
2135 string it parses it instead of the library, even though library
2136 encodes the formatted string. If the callback function is not
2137 provided then the library will use the string as is. The
2138 affected file is lib/silcclient/silcapi.h.
2140 * All the nickname strings passed to the client library in
2141 commands are now expected to be formatted nickname strings.
2142 If the command does not support the formatted nickname string
2143 it will assume that the sent string is the actual nickname.
2144 Affected file lib/silcclient/command.c.
2146 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2148 * Added public key authentication support to OPER and SILCOPER
2149 commands in the client library. Affected file is
2150 lib/silcclient/command.c.
2152 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2154 * Changed the get_auth_methdod client operation to be asynchronous.
2155 It can be async if the application resolves the authentication
2156 method from the server during the negotiation. Added new
2157 SilcGetAuthMeth completion callback that the application will
2158 call after resolving the authentication method.
2160 Added function silc_client_request_authentication_method that
2161 the application can use to resolve the authentication method
2162 from the server. Added also SilcConnectionAuthRequest callback
2163 that the library will call after the server has replied. The
2164 application can call this function if it does not know the
2165 current authentication method.
2167 Affected files are lib/silcclient/client.c and
2168 lib/silcclient/silcapi.h.
2170 * The Irssi SILC client now automatically resolves the authentication
2171 method incase any configuration information is not present (and
2172 currently there never is). The affected file is
2173 irssi/src/silc/core/client_ops.c.
2175 * Fixed public key authentication from the client library.
2176 Affected file lib/silcclient/protocol.c. Changed also the
2177 protocol specification about the public key authentication in
2178 the connection authentication protocol. The actual data to be
2179 signed is now computed with a hash function before signing.
2181 * Fixed the public key authentication from the server as well.
2182 Affected file silcd/protocol.c.
2184 * Removed the mlock()'s from the memory allocation routines.
2185 Affected file lib/silcutil/silcmemory.c. The ./configure does
2186 not check anymore for the mlock(). Affected file is
2189 * Fixed USERS command in server to allow the execution of the
2190 command for private and secret channels if the client sending
2191 the command is on the channel. Affected file silcd/command.c.
2193 * Fixed silc_client_get_clients_local to return the clients
2194 count correctly. It could return wrong value. Affected file
2195 lib/silcclient/idlist.c.
2197 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2199 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2200 types. The assembler optimizations seemed not to like 64-bit
2201 data types. The assmebler optimizations thus are now enabled
2202 also for BSD systems as opposed to only enable them for Linux.
2204 * Do not check for threads at all on BSD systems. Affected
2205 file configure.in.pre.
2207 * Removed -n and -h options from the Irssi SILC Client since
2208 they are not used in silc.
2210 * Fixed the prime generation to assure that the first digit
2211 of the generated random number is not zero since our conversion
2212 routines does not like number strings that starts with zero
2213 digit. If zero digit is seen the random number is regenerated.
2214 This caused some corrupted RSA keys when the zero first digit
2215 was met. Affected file lib/silcmath/silcprimegen.c.
2217 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2219 * Fixed WIN32 configuration in the ./configure script.
2220 Fixed to include xti.h on environments that has it.
2221 Patches by Carsten Ilchmann and andrew.
2223 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2225 * Changed the silc_id_create_client_id to be collision
2226 resistant. It is now assured that there cannot be created
2227 two same client ID's. I suspect that some weird bugs in
2228 the server were actually caused by duplicate Client IDs.
2229 Affected file silcd/serverid.[ch]. A router receiving
2230 new ID now also assures and informs the sending server
2231 if the ID caused collision.
2233 * Changed the silc_id_create_channel_id to also assure that
2234 there are no collisions.
2236 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2238 * Statement about ignoring the Mutual Authentication flag when
2239 performing rekey with PFS was a bit misleading. It is ignored
2240 if it was set in the initial negotiation, it cannot be even
2241 set in the rekey. Fixed in the ke-auth draft. Started the
2242 new versions of the protocol drafts in the doc/.
2244 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2246 * Fixed a bug in silc_client_command_identify_save when saving
2247 new channel information. The channel name was no duplicated
2248 and caused crash on exit. Affected file is
2249 lib/silcclient/command_reply.c.
2251 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2253 * Fixed the getkey command handling in the server. Send just
2254 empty OK reply to the sender if the key could not be fetched
2255 (but everything else was ok, like the key just was not available).
2256 Changed the public key parameter to optional in the protocol
2257 specs so that empty OK reply can be sent. Affected file
2260 Added a message to Irssi SILC client to tell to user if the
2261 server did not return a public key.
2263 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2265 * Fixed a channel key regeneration bug. It registered new
2266 timeout tasks exponentially until all system resources were
2267 used. Affected file silcd/server.c.
2269 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2271 * Added the SILC Document generator to the scripts/silcdoc.
2272 It can be used to generate the Toolkit Reference Manual out
2273 of the source tree. Internally it will also use the RoboDoc
2274 generator now imported in util/robodoc.
2276 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2278 * Added couple of return's in rekey protocol if error orccurred
2279 during the protocol. The execution must be terminated.
2280 Affected file silcd/protocol.c. Also, terminate the protocol
2281 always with timeout.
2283 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2285 * The client's Client ID was created initally from the wrong
2286 nickname (it could have been in format nick@host) in the
2287 silc_server_new_client. Affected file silcd/packet_receive.c
2289 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2291 * Added some SILC_LOG_ERROR's to various error conditions
2292 if client could not be added to ID cache. Affected files
2293 silcd/packet_receive.c and silcd/server.c.
2295 * When client's sock->user_data is freed, NULL also the
2296 client->router and client->connection pointers. Added check
2297 for these pointers being NULL to various places around the
2298 code. Affected file silcd/server.c.
2300 * Added client->data.registered == TRUE checks to various
2301 places around the code to assure that unregistered client's
2302 are not handled when it is not allowed. Affected file
2305 * Added `bool registered' fields to all
2306 silc_idlist_[server|client]_get_* routines to indicate whether
2307 the fetched client needs to be registered or not. Affected
2308 file silcd/idlist.[ch].
2310 * Add your own entry as registered to the ID cache in the
2311 server. Affected file server.c.
2313 * Fixed a bug in silc_server_new_server. The SilcServer was
2314 set as the new server's context instead of SilcServerEntry.
2315 This naturally caused some weird bugs.
2317 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2319 * Do not delete the channel rekey task when adding it
2320 for in silc_server_create_channel_key.
2322 * Changed the silc_server_create_channel_key to return
2323 TRUE or FALSE to indicate the success of the channel key
2326 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2328 * Fixed MSVC++ project files and added missing files to
2329 Makefiles under win32/.
2331 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2333 * Do not add TCP_NODELAY flag if the operating system
2334 does not have it defined. Affected files are
2335 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2337 * Fixed buffer overflow from Irssi SILC Client. Affected
2338 file irssi/src/fe-common/core/themes.c.
2340 * Fixed double free in client library in the file
2341 lib/silcclient/client.c when disconnecting from server.
2343 * Applied double free patch from cras to Irssi SILC client.
2344 Affected files irssi/src/core/[modules/expandos].c
2346 * Fixed the disconnection handling to Irssi SILC Client.
2347 The application must call silc_client_close_connection
2348 in ops->connect client operation in case of failure of
2349 the connection. Affected file is
2350 irssi/src/silc/core/client_ops.c.
2352 * Do not set sock->protocol to NULL in the function
2353 silc_client_close_connection after executing the protocol's
2354 final callback since the sock might not be valid anymore.
2355 Affected file lib/silcclient/client.c.
2357 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2359 * Do not enable SILC_THREADS if the linking with libpthread
2360 did not happen. Affected file configure.in.pre.
2362 * Added notion to protocol specification that server must
2363 verify the sent authentication payload with CMODE when
2364 setting the channel founder key. Implemented it to the
2365 server. Affected file silcd/command.c.
2367 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Added _EXTRA_DIST SILC distribution variable to the
2370 distributions file. It is used to conditionally add extra
2371 files or directories to the specific distribution. Affected
2372 files ./prepare, Makefile.am.pre and distributions.
2374 Removed the `_' from the start of the distribution names.
2377 * Added README.WIN32 for instructions to compile the Toolkit
2380 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2382 * Fixed a double free in disconnection in the server. Affected
2383 file is silcd/server.c.
2385 * Fixed the lib/silcske/groups.c to work now also with GMP
2386 MP library. The string conversion did not work when using
2387 specific base and the base is indicated in the string as well.
2389 * Created win32/ directory which now includes MSVC++ specific
2390 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2391 It will appear only in the toolkit distribution
2393 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2395 * Changed the key material distribution function in case when
2396 the hash output is too short. The data is now concatenated
2397 a bit differently than it used to. Made the change to the
2398 SKE protocol specification.
2400 * Added better GMP detection to configure.in.pre. A patch
2403 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2405 * Fixed a minor bug in SKE that might cause some problem on
2406 some platforms. Affected file lib/silcske/silcske.c.
2408 * Added the cookie checking for initiator in the SKE. It checks
2409 that the responder returns the sent cookie unmodified. The
2410 affected file is lib/silcske/silcske.c. Added new SKE
2411 error type INVALID_COOKIE that can be sent during the
2412 negotiation. Fixed some memory leaks as well.
2414 * Added the "invalid cookie" error message to Irssi SILC client's
2417 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2419 * Added `task_max' field to the SilcClientParams to indicate
2420 the maximum tasks the scheduler can handle. If set to zero,
2421 default values are used. Affected file lib/silcclient/silcapi.h.
2423 * Fixed memory leaks in silc_client_close_connection. Affected
2424 file lib/silcclient/client.c.
2426 * Added silc_client_del_client_entry to client library to free
2427 all memory of given client entry. Affected file is
2428 lib/silcclient/idlist.[ch].
2430 * Added new functions silc_client_del_channel and
2431 silc_client_del_server to delete channel and server entries.
2432 Affected file lib/silcclient/[silcapi.h/idlist.c].
2434 * Removed silc_client_del_client_by_id from silcapi.h.
2436 * Fixed the INFO command to return the server's own info
2437 correctly when querying by Server ID. Affected file is
2440 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2442 * Removed the non-blocking settings in WIN32 code in the
2443 silc_sock_[read/write] and added SleepEx instead. Affected
2444 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2445 of input data is now checked with FIONREAD and ioctlsocket.
2447 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2449 * Call silc_schedule_task_del_by_context in the
2450 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2451 Affected file lib/silccore/silcprotocol.c.
2453 * Call silc_protocol_cancel for active protocols in the
2454 silc_server_close_connection if the funtion
2455 silc_server_free_sock_user_data has not been called.
2456 Affected file silcd/server.c.
2458 * Generic tasks cannot be deleted using the del_by_fd
2459 task deleting function since generic tasks does not match
2460 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2462 * Added a notion to SILCOPER help file that the SILCOPER works
2463 only on router server, not on normal server.
2465 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2467 * Added for WIN32 support for the new scheduler as well.
2468 Affected file lib/silcutil/win32/silcwin32schedule.c.
2470 * Fixed the SHA1 implementation to work on various platforms.
2472 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2474 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2475 API. It is part of the scheduler now. Everything else is
2476 as previously but some functions has changed their names.
2477 Checkout the lib/silcutil/silcschedule.h for the interface.
2478 Updated all applications to use the new interface. Affected
2479 files are lib/silcutil/silcschedule.[ch].
2481 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2483 * Found a bug in the SKE implementation. The HASH value,
2484 specified by the protocol, was not computed correctly. The
2485 public key of the responder was not added to the computation
2486 even though it is mandatory. Affected file lib/silcske/silcske.c.
2487 This unfortunately causes incompatibilities with older
2488 clients and servers.
2490 * Added WIN32 specific network init and uninit functions:
2491 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2492 the Winsock2. Affected file lib/silcutil/silcnet.h and
2493 lib/silcutil/win32/silcwin32net.c.
2495 * Set the socket always to nonblocking mode on WIN32 after
2496 reading data or writing data. Affected file is
2497 lib/silcutil/win32/silcwin32sockconn.c.
2499 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2501 * Fixed various compilation problems under WIN32. Affected
2502 files lib/silcutil/win32/silcwin32thread.c and
2503 lib/silcutil/win32/silcwin32schedule.c.
2505 * Removed all _internal.h #includes from public header
2506 files. Internal headers must never be included from
2509 Removed also the lib/silcske/payload_internal.h file.
2511 * All include files that may be needed (public and some others
2512 included by the public headers) by application developers are
2513 now copied to the ./includes directory. It does not copy any
2514 internal headers. Affected file Makefile.defines.pre and all
2515 Makefile.am's under lib/ and subdirs.
2517 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2519 * Do not change the ~/.silc directory's permissions automatically.
2520 Affected file irssi/src/silc/core/clientutil.c.
2522 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2524 * Do not cancel the protocol in silc_server_close_connection
2525 it might cause recursion. Now cancelled in the function
2526 silc_server_free_sock_user_data. Affected file silcd/server.c.
2528 * Fixed the silc_server_remove_clients_by_server to regenerate
2529 the channel keys correctly finally. Added also new function
2530 silc_server_remove_clients_channels to actually do it.
2531 Affected file silcd/server.c.
2533 * Fixed the silc_server_new_channel to not crash by giving
2534 wrong router to the new channel. Affected file is
2535 silcd/packet_receive.c.
2537 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2539 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2540 which is given as argument to the silc_client_alloc now.
2541 It can be used to configure the client and set various parameters
2542 that affect the function of the client.
2544 * The USERS command in server did not check whether the channel
2545 is private or secret. Affected file silcd/command.c.
2547 * Added new argument to the USERS command in protocol specification.
2548 The USERS command now can take the channel name as argument
2549 as well. Added support for this in client and server and
2550 updated the protocol specs.
2552 * Completed the GETKEY command in client. It can be now used
2553 to fetch also servers public key not only some clients.
2554 Affected files lib/silcclient/command[_reply].c.
2556 * Added silc_client_get_server to return server entry by the
2557 server name. Affected files lib/silcclient/silcapi.h and
2560 * Redefined the IDENTIFY command in protocol specification to be
2561 more generic. It now can be used to query information about
2562 any entity in the SILC Network, including clients, servers and
2563 channels. The query may be based either the entity's name
2564 or the ID. Added support for this in both client and server.
2566 Affected files silcd/command.c and lib/silcclient/command.c
2567 and command_reply.c.
2569 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2570 the _from_client and _from_server functions. Affected file
2573 * Added silc_client_get_channel_by_id_resolve to the file
2574 lib/silcclient/silcapi.h to resolve channel information by
2575 its ID. Added also silc_client_get_channel_by_id that
2576 does not resolve it from the server.
2578 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2580 * Added SilcServerEntry context into the client library
2581 to represent one server. The INFO command now allocates
2582 these to save the resolved server info. For now on the
2583 client library will also keep information about servers,
2584 connected and resolved with INFO.
2586 The INFO command now allocates the SilcServerEntry context
2587 and saves the server info there. The COMMAND_REPLY in
2588 the INFO now returns the parameters to application in
2589 same order as defined in the protocol specification.
2591 The entries are cached in the client->server_cache.
2593 * The INFO command is now issued after received the Client ID
2594 from the server. Affected file lib/silcclient/client.c.
2596 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2597 to the application as the mode changer might be server.
2598 It is guaranteed that NULL is not returned anymore to the
2599 application. Affected file lib/silcclient/client_notify.c.
2601 The ID Type is now also passed to the application so that
2602 it can check whether the returned entry is SilcClientEntry
2605 Added new function silc_client_get_server_by_id to return
2606 the server entry by ID. Affected files are the
2607 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2609 * Do not create the channel in the Irssi SILC Client when issuing
2610 the JOIN command but when received the sucessful JOIN command
2611 reply. Otherwise the channel might get created even though we
2612 could not join it. The Affected file is
2613 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2615 * Fixed a channel joining bug in router. The router must also
2616 check the channel modes, invite and ban lists etc. when serving
2617 the JOIN command sent by normal server. Affected file is
2618 silcd/command.c. The router now resolves the client's
2619 information from the server who sent the JOIN command if it
2620 does not know it, and processes the JOIN command only after
2623 * Changed the SilcCommandCb to take new argument; void *context2.
2624 Affected file lib/silccore/silccommand.h
2626 The second argument in the command callbacks in the server now
2627 includes the SilcServerCommandReplyContext if the command was
2628 called as pending command callback from the command reply.
2629 Otherwise it is NULL. When called as pending the status of the
2630 command reply will be checked and if it was erronous the
2631 error will be sent to the original sender of the command.
2632 This way the client always receives the error messages even
2633 though the server was actually the one who received the error
2634 when it resent the command to router, for example. Affected
2635 files silcd/command[_reply].[ch].
2637 * Fixed sending WHOWAS command's error message to client if
2638 the requested client could not be found. It was missing.
2641 * Changed the CMODE and CUMODE commands reply arguments in the
2642 protocol specification. The Channel ID is now sent in both
2643 of the commands to identify the channel. Implemented this
2644 new feature to the client and server. Affected files
2645 lib/silcclient/command_reply.c and silcd/command.c.
2647 * Made better checks for invite and ban lists in the JOIN
2648 command in server. Affected file silcd/command.c.
2650 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2652 * The server now performs the incoming host IP/DNS lookup
2653 using the silc_socket_host_lookup and thus does not block
2654 the server anymore. Affected file silcd/server.c.
2656 * Completed the multi-thread support for SILC Scheduler in
2657 the lib/silcutil/silcschedule.c.
2659 * Fixed the configure.in.pre to detect the pthread correctly
2662 * Fixed a deadlock in silc_task_queue_wakeup in the file
2663 lib/silcutil/silctask.c.
2665 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2667 * Added new function silc_schedule_wakeup that is used in
2668 multi-threaded environment to wakeup the main thread's
2669 schduler. It needs to be used when a thread adds a new task
2670 or removes a task from task queues. After waking up, the
2671 scheduler will detect the task queue changes. If threads
2672 support is not compiled in this function has no effect.
2673 Implemented the wakeup mechanism to both Unix and WIN32
2674 systems. Affected files are lib/silcutil/silcschedule.[ch],
2675 lib/silcutil/unix/silcunixschedule.c and the
2676 lib/silcutil/win32/silcwin32schedule.c.
2678 * Added new function silc_task_queue_wakeup to wakeup the
2679 scheduler by the specified task queue. Affected file
2680 lib/silcutil/silctask.[ch].
2682 * The silc_socket_host_lookup_start now wakes up the scheduler
2683 after adding the timeout task. Affected file is
2684 lib/silcutil/silcsockconn.c.
2686 * The silc_socket_host_lookup is synchronous now if the threads
2687 support is not compiled in. However, the callback is still
2688 called asyncronously through the scheduler, anyway. Affected
2689 file lib/silcutil/silcsockconn.c.
2691 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2693 * Added new function silc_socket_host_lookup to perform
2694 asynchronous IP and FQDN lookups for the socket connection.
2695 Affected files lib/silcutil/silcsockconn.[ch].
2697 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2699 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2700 that may or may not compile the mutex support in.
2702 Changed the silc_mutex_alloc interface. It allocates the
2703 mutex now to the sent pointer and returns TRUE or FALSE.
2705 Affected file lib/silcutil/silcmutex.h.
2707 * Wrote the SILC Task Queue interface to support multi-threads.
2708 Affected file lib/silcutil/silctask.[ch].
2710 * Wrote the SILC Scheduler to support multi-threads. Affected
2711 file lib/silcutil/silcschedule.c.
2713 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2715 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2716 in lib/silcutil/win32/.
2718 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2720 * Defined SILC Mutex API and SILC Thread API and implemented
2721 them for Unix. Affected files are
2722 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2723 lib/silcutil/unix/silcunixmutex.c and
2724 lib/silcutil/unix/silcunixthread.c.
2726 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2728 * Fixed the silc_server_remove_clients_by_server's channel
2729 key re-generation. The hash table handling was incorrect
2730 and would not work with many channels. Affected file is
2733 * Fixed some memory leaks around the server code.
2735 * Rewrote the silc_server_get_users_on_channel to support IPv6
2736 based Client ID's. Affected file silcd/server.c.
2738 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2739 specification. However, a separate document must be written
2740 to define the detailed signing procedure and the payload
2741 associated with the flag. Defined the flag to the
2742 lib/silccore/silcchannel.h as well.
2744 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2746 * Changed the dynamic tables to static size tables in the
2747 lib/silccrypt/silchmac.c.
2749 * Removed GCC dependencies from the code. A patch by cras.
2751 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2753 * Do not show the error "Error receiving packet bla bla"
2754 in server if it really was not an error (-2 means that reading
2755 is pending). Affected file silcd/server.c.
2757 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2759 * Fixed a possible crash in silc_server_remove_clients_by_server
2760 in silcd/server.c. Fixed there also some memory leaks.
2762 * Fixed the silc_idlist_replace_client_id. It could replace
2763 wrong key in the hash table. Affected file silcd/idlist.c.
2765 * Do not check whether there are global users on the channel
2766 if the channel->global_users is FALSE. Affected functions
2767 silc_server_remove_from_one_channel and
2768 silc_server_remove_from_channels in silcd/server.c. Also,
2769 do not check if the removed client is local as we can be
2770 sure that global client was not removed from the channel
2771 and checking for global users is not needed.
2773 * The silc_server_remove_clients_by_server now re-generates
2774 the channel keys correctly for those channels that had
2775 clients removed from them. Affected file silcd/server.c.
2777 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2779 * Found the reason of random crashes in the server. We weren't
2780 ignoring the SIGPIPE signal (which can be sent in write())
2781 and it crashed the server. Affected file silcd/silcd.c.
2783 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2785 * Assure that sock->user_data is not NULL in the function
2786 silc_server_packet_send in silcd/packet_send.c.
2788 * Disconnect the remote connection if it could not be added
2789 to any ID lists in the server. The affected file is
2792 * Check in silc_server_packet_send[_real/dest] that the
2793 socket is not disconnecting and ignore the data if it is.
2794 Affected file silcd/packet_send.c.
2796 * Define inline to __inline on native WIN32 compilation.
2797 Affected file includes/silcwin32.h.
2799 * Added some explicit type casts for inline code since MSVC
2800 require them. Affected files lib/silcutil/silcbuffer.h,
2801 lib/trq/silcdlist.h and lib/trq/silclist.h.
2803 * Print warning in log files from now on if the packet
2804 decryption fails. Affected file silcd/server.c.
2806 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2808 * Changed the `say' client operation's interface to accept
2809 new `type' argument to indicate the type of the message sent
2810 by the library. The application may filter the library's
2811 messages according the type. The affected file is the
2812 lib/silcclient/silcapi.h.
2814 * Added two new functions to lib/silcclient/silcapi.h:
2815 silc_client_del_client and silc_client_del_client_by_id.
2816 Affected file lib/silcclient/idlist.c.
2818 * Moved the clientincludes.h from includes/ to silc/ and
2819 serverincludes.h from includes/ to silcd/.
2821 * The modes for the CMODE and CUMODE are now passed as
2822 uint32 for application with COMMAND_REPLY. The affected
2823 file is lib/silcclient/command_reply.c.
2825 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2827 * /WHOIS without arguments shows client's own information.
2828 Affected file lib/silcclient/command.c.
2830 * Changed PING to not accept any arguments. The specs
2831 says that client can ping only the connected server so
2832 requiring an argument is not needed. Affected file is
2833 lib/silcclient/command.c.
2835 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2837 * Fixed a fatal bug in private message sending and reception
2838 encryption and decryption when using private message keys.
2839 The implementation was incorrect and did not follow the
2840 specification. It causd that some of the message were
2841 lost since it did not use the sending and receiving keys
2842 as the protocol suggests. This has been fixed and will cause
2843 incompatibilities with older clients when sending private
2844 message encrypted with private message keys. Affected files
2845 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2846 and various other in Irssi SILC Client.
2848 Added `responder' boolean argument to the functions
2849 silc_client_add_private_message_key[_ske] to indicate when
2850 the key is added as responder or initiator of the key
2853 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2855 * Removed the silc_ske_check_version function and created
2856 a SilcSKECheckVersion callback. Added also a function
2857 silc_ske_set_callbacks that is now used to set all SKE
2858 callbacks. The callback functions are not given to
2859 the SKE functions anymore, but this function is used to
2862 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2864 * Added `silc_version' argument to the silc_client_alloc
2865 to define the version of the application for the library.
2866 The library will use the version string to compare it
2867 against the remote host's (usually a server) version
2868 string. Affected file lib/silcclient/silcapi.h
2870 * Added the KE protocol context to Key Agreement context
2871 in client library so that we can abort the SKE if it
2872 is in process when we get timeout. Affected file is
2873 lib/silcclient/client_keyagr.c.
2875 * Do not resolve the client ID forever if it returns in the
2876 first time that such client does not exist. This was done
2877 for example with private message. Affected file is
2878 lib/silcclient/client_prvmsg.c.
2880 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2882 * Do not add regex.h for WIN32. The affected file
2883 includes/silcincludes.h.
2885 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2886 not work yet 100%. It generates the DLL's automatically
2887 when compiling with --with-win32 under cygwin.
2889 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2891 * lib/contrib/regex.c is not compiled on WIN32.
2893 * Added silc_net_get_socket_opt function to the
2894 lib/silcutil/silcnet.h.
2896 * Added includes/silcwin32.h for WIN32 specific includes
2899 * Do not use ptime structure or any of the posix process
2900 functions on WIN32 in lib/silccrypt/silrng.c.
2902 * Added silc_gettimeofday to provide generic function
2903 for struct timeval on all platforms. Added the function
2904 to lib/silcutil/silcutil.h.
2906 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2908 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2909 library as they clearly belong there. As a plus side we
2910 can make the actual socket connection routines platform
2913 Added also new generic function silc_socket_read and
2914 silc_socket_write (that used to be silc_packet_[read/write].
2915 The implementation of these are platform specific.
2917 * Added WIN32 specific routines of silc_socket_[read/write]
2918 to lib/silcutil/win32/silcwin32sockconn.c.
2920 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2922 * Added preliminary support for native WIN32 compilation under
2923 cygwin (using the -mno-cygwin option for GCC) to the
2924 ./configure.in.pre. The --with-win32 now prepares the
2925 compilation for native WIN32.
2927 * Rewrote the SILC Scheduler interface in the file
2928 lib/silcutil/silcschedule.h. The scheduler is now context
2929 based and does not have anymore any global static scheduler.
2930 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2931 and created lib/silcutil/win32 directory for WIN32 based
2934 * Added Unix specific network routines to the
2935 lib/silcutil/unix/silcunixnet.c and the old
2936 lib/silcutil/silcnet.c includes now only generic routines.
2938 Added WIN32 specific network routines to the
2939 lib/silcutil/win32/silcwin32net.c.
2941 * Added Unix specific utility functions from the
2942 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2944 * Added WIN32 SILC Scheduler to the file
2945 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2948 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2950 * Do not handle JOIN notify in the server if the target client
2951 is not registered (idata->registered == FALSE). The affected
2952 file is silcd/packet_receive.c.
2954 * Update the nickrec->founder in event_cumode in the Irssi SILC
2955 client. Affected file irssi/src/silc/core/silc-channels.c.
2957 * Fixed the CUMODE_CHANGE notify handling in the server when
2958 server and router are announcing their clients on channels.
2959 Now the mode changes are saved and notified correctly. The
2960 affected file is /silcd/packet_receive.c.
2962 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2963 They really did not replace the cache entry in the ID Cache.
2964 Now they do that. Affected file silcd/idlist.c.
2966 * Fixed the KICK notify handling in the Irssi SILC client to
2967 update the channel records so that the kicked client does not
2968 appear to be on the channel. The affected file is
2969 irssi/src/silc/core/silc-channels.c.
2971 * Always update the conn->current_channel when executing command
2972 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2974 * Fixed the KILL notify handling in Irssi SILC client to remove
2975 the killed client on all channels.
2977 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2979 * Fixed the silc_parse_command_line to remove extra spaces
2980 from the start and end of the arguments. Affected file is
2981 lib/silcutil/silcutil.c.
2983 * Cancel and free any active protocol in the function
2984 silc_server_close_connection. Affected file silcd/server.c.
2986 * Cancel and free any active protocol in the function
2987 silc_client_close_connction. Affected file is
2988 lib/silcclient/client.c.
2990 * Do not execute the KILL command for clients that are in
2991 history (ie. they are not in the network). Affected file is
2994 * Fixed KILL notify handling, client does not crash anymore.
2995 Affected file irssi/src/silc/core/silc-channels.c.
2997 * Reduced the default packet buffer size from 2048 to 1024 in
2998 lib/silccore/silcpacket.c.
3000 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3001 counter to the SKE context that is incresed when the SKE library
3002 performs async operation outside the library. If the outside
3003 process frees the SKE context and FREED status will be set
3004 and the library will detect after the sync operation that the
3005 libary is freed. The affected files are
3006 lib/silcske/silcske[_status].[ch].
3008 * Resolve the client entry information in the function
3009 silc_client_channel_message to assure that NULL pointer is not
3010 passed as client entry to the application. */
3012 * Fixed the task timeout calculation to assure that there is
3013 never negative timeouts. The affected file is
3014 lib/silcutil/silcschedule.c.
3016 * Fixed the channel user mode notification sending in server.
3017 It was sent point-to-point to the router (or to server by router)
3018 but it needs to be destined to a channel. The routines now
3019 supports sending the channel user mode notifys to the channels
3020 when announcing clients and channels. Affected files are
3021 silcd/server.c and silcd/packet_receive.c.
3023 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3024 It did not actually replace the old channel entry in the cache.
3025 Affected file lib/silcclient/client_notify.c.
3027 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3029 * Fixed a possible crash in silc_packet_send_prepare. It now
3030 assures always that there is enough space in the buffer and
3031 at the tail area of the buffer (for MAC).
3033 Fixed the inbound buffer reallocation in silc_packet_read.
3034 It was old code and did not handle the reallocation correctly.
3037 The affected file is lib/silccore/silcpacket.c.
3039 * Fixed buffer overflow in silc_parse_nickname in the file
3040 lib/silcutil/silcutil.c.
3042 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3044 * make install generates new server keys only if there is not
3047 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3049 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3050 Added check that if the NOREPLY is set then we will not send
3051 the away message. This avoids infinite loop of away messages
3052 if both clients are away. The affected file is
3053 lib/silcclient/client_prvmsg.c.
3055 * Fixed client crash if /NICK was given without arguments.
3056 Affected file lib/silcclient/command.c.
3058 * Server does not send the invite list in INVITE command back
3059 to the client if the list was not altered. Added this notion
3060 to the protocol spec as well. Affected file silcd/command.c.
3062 Fixed possible crash in INVITE command by checking the
3063 value of silc_server_get_client_route command.
3065 * Fixed the INVITE notify type handling. The arguments are now
3066 taken in correct order and client does not crash. The affected
3067 file is irssi/src/silc/core/silc-channels.c.
3069 Removed the "Inviting xxx to channel" message from the
3070 client library away and let the application handle it.
3071 Affected file lib/silcclient/command.c. Added that message
3072 to Irssi SILC client's message formats.
3074 * Fixed CMODE command crash in client. It now checks the
3075 amount of arguments correctly and does not crash. The affected
3076 file is lib/silcclient/command.c.
3078 * Do not create new channel automatically in silc_channels_join
3079 but check whether the channel by that name already exists.
3080 Affected file irssi/silc/core/silc-channels.c.
3082 * Do not send the SERVER_SIGNOFF to router if the disconnected
3083 entity was the router. Affected file silcd/server.c.
3085 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3086 SILC client as it was missing from there.
3088 Added the handling of the KICK notify to the Irssi SILC client
3089 as it was missing. Added "you have been kicked" message to
3090 Irssi SILC client's message modules formats.
3092 Added the handing of the KILL notify to the Irssi SILC client
3093 as it was missing. Added the kill message module formats
3096 The affected file is irssi/src/silc/core/silc-channels.c.
3098 * The router did not save the channel mode the server announced.
3099 Affected file silcd/packet_receive.c.
3101 * Fixed a possible crash in INFO command in server. If the
3102 server did not provide the server info it crashed. Affected
3103 file silcd/command.c.
3105 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3107 * Fixed the GETKEY command in the server to check also the
3108 global list. Otherwise the GETKEY would not work correctly
3109 in normal SILC server. Affected file silcd/command.c.
3111 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3113 * Fixed GETKEY crash, it crashed if the command did not succseed.
3115 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3117 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3118 is now real and not just an macro interface to GMP.
3120 Removed the entire GMP from the source tree and imported new
3121 NSS MPI library instead. Reason for removing GMP is that it is
3122 extremely large and compiles extremely slow. The NSS MPI
3123 is only a few files and compiles in less than 10 seconds.
3124 The speed is also about the same as GMP. The MPI is imported
3125 to lib/silcmath/mpi.
3127 If the system has GMP installed we will still use the GMP.
3128 If it is not then the NSS MPI will be compiled.
3130 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3132 * Merged a long nickname (127 characters long) crash bugfix from
3133 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3135 * Merged a freed memory reference bugfix from Irssi CVS tree.
3136 Affected file irssi/src/core/commands.c.
3138 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3140 * Added the server's public key sving and verification to the
3141 server when performing the SKE. This was missing and the
3142 remote server's (or router's) public key was accepted without
3143 checking whether we have it previously or trust it at all.
3144 Affected file silcd/protocol.c.
3146 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3148 * Check in the silc_server_timeout_remote if protocol is active
3149 and make sure that the protocol's final callback is called so
3150 that all memory if freed. Affected file silcd/server.c.
3152 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3154 * silc_server_whois_send_reply crashed the server if the nickname
3155 was 127 characters long. Affected file silcd/command.c.
3157 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3159 * Added sanity check to the silc_server_new_client. If the hostname
3160 is provided inside username then check that the provided hostname
3161 really is the same as the resolved one. If the hostname was not
3162 resolved then check it from the public key. Affected file is
3163 silcd/packet_receive.c.
3165 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3166 if the server disconnected us and the connection is not valid
3167 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3169 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3170 the library to the lib/silcutil/silcutil.[ch].
3172 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3174 * Close log file after open. Affected file
3175 lib/silcutil/silclog.c.
3177 * Check whether sock == NULL in silc_client_send_packet and return
3178 if it is. Affected file lib/silcclient/silcclient.c.
3180 * Check rec->entry == NULL in the Irssi SILC Client before
3181 sending the channel message. Affecte file is
3182 irssi/src/silc/core/silc-servers.c.
3184 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3186 * Merged a splitted window bugfix from Irssi CVS tree. The
3187 affected file is irssi/src/fe-text/textbuffer-view.c.
3189 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3190 It did not print nickname.
3192 * Improved the distributions system a bit.
3194 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3196 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3197 irssi/src/fe-text/gui-window.c.
3199 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3200 to in-active server. The affected file is
3201 irssi/src/silc/core/client_ops.c.
3203 * Resolve the client in USERS command reply if the entry does
3204 not have username resolved. The affected file is
3205 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3206 command to WHOIS command to really resolve stuff. The USERS
3207 is not used any more in any critical section so WHOIS can
3208 be used even though it might be slower than IDENTIFY.
3210 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3213 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3215 * Changed the protocol API a bit more consistent in the
3216 lib/silccore/silcprotocol.[ch].
3218 * Changed the following headers to ROBODoc format:
3220 lib/silccore/silcpayload.h
3221 lib/silccore/silcprotocol.h
3222 lib/silccore/silcsockconn.h
3224 All core library headers are now formatted.
3226 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3228 * Fixed a bug in Irssi SILC client; do not show that you are
3229 server/router operator if you really are not. Affected file is
3230 irssi/src/silc/core/client_ops.c.
3232 * Renamed silc_command_free_payload to silc_command_payload_free.
3233 Affected file lib/silccore/silccommand.h
3235 * Added silcmath.h to include the prototoypes of various routines
3236 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3239 * Changed the following headers to ROBODoc format:
3241 lib/silccore/silcchannel.h
3242 lib/silccore/silccommand.h
3243 lib/silccore/silcid.h
3244 lib/silccore/silcidcache.h
3245 lib/silccore/silcmode.h
3246 lib/silccore/silcnotify.h
3247 lib/silccore/silcpacket.h
3248 lib/silcmath/silcmath.h
3250 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3252 * Added checking to the server code not to start the server if
3253 ciphers and stuff are not configured properly. Affected files
3254 silcd/serverconfig.[h] and silcd/server.c.
3256 * Changed the layout of the header files of the public interfaces
3257 in the SILC libraries. The new layout supports ROBODoc
3258 documentation tool (and some others) so that it is easy to create
3259 a library reference manual. All the other headers and source
3260 code must still follow the CodingStyle document. Also source
3261 code must not include these ROBODoc stuffs, only the headers.
3262 Furthermore, all public interface headers must now be named
3263 by using `silc' prefix, example: silcapi.h, silccipher.h.
3264 Some files were renamed due to this. All the other headers
3265 must not be used as public interfaces. I will update the
3266 CodingStyle document later. Changed following headers, so far:
3268 lib/silcclient/silcapi.h
3269 lib/silccore/silcauth.h
3270 lib/silccore/silcprivate.h
3271 lib/silccrypt/silcdh.h
3273 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3277 * Removed silc_client_packet_send_flush from the client library
3278 as it is not needed. Affected file lib/silcclient/client.[ch].
3280 * Added printing of message of unresolved authentication method
3281 to the Irssi SILC client. Added it to the module formats.
3282 Removed the same message from the client library.
3284 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3286 * Added new distribution feature, DISTLABEL. Every distribution
3287 can define own preprocessor label that can be used in the
3288 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3289 file distributions, acconfig.h.pre and prepare.
3291 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3293 * Added Makefile.defines_int to include the actual definitions
3294 for Makefile.defines.in. Tested the new distribution system,
3295 created distributions and tested installation.
3297 * Added AWAY message printing to the Irssi SILC client. Added
3298 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3300 * Added SCONNECT command to call the SILC's CONNECT command.
3301 Cannot use CONNECT directly since Irssi uses that internally.
3302 Affected file irssi/src/silc/core/silc-servers.c.
3304 Added ACTION local command. It is same as ME command but takes
3305 the channel as mandatory argument.
3307 Rewrote some of the Irssi's help files to suite for SILC
3310 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3312 * Added Makefile.defines[.in] that should for now on be included
3313 in all Makefile.am file in the source tree. That file includes
3314 all common compilation definitions for SILC source tree.
3316 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3318 * Minor changes to the ./prepare script to change the package
3319 name according the distribution name to the configure.in.
3321 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3323 * Created new distribution system. Added file `distributions'
3324 that defines all the distributions that can be created out of
3325 the SILC source tree. The ./prepare script now reads that
3326 file to determine how to prepare the distributions. The
3327 first argument to the ./prepare is the name of the distribution
3328 and second is the version of the distribution. If given
3329 without arguments it creates the default (toolkit) distribution
3330 with the default version (defined in ./prepare).
3332 All Makefile.am files that are subject to the distributions
3333 are now named as Makefile.am.pre. These are ./Makefile.am
3334 and lib/Makefile.am. Others may be changed later.
3336 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3338 * Added invite list, ban list, some key management and connection
3339 error message printing to module formats in the Irssi SILC client.
3341 * Added new silc_client_set_away_message to set the away message
3342 that is back to the person who sent private message. The
3343 affected file lib/silcclient/silcapi.h and the
3344 lib/silcclient/client_prvmsg.c.
3346 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3348 * Fixed the private message sending in the Irssi SILC client,
3349 added local command KEY to the Irssi SILC client.
3351 Added key management and key agreement message formats to the
3352 irssi/src/fe-common/silc/module-formats.[ch].
3354 Added USERS (alias WHO) printing, server/router operator
3355 indication and LIST command printing to the module formats.
3357 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3359 * Fixed channel joining notify handling, cumode notify handling
3360 from Irssi SILC client.
3362 * Added SILC specific module-formats to the Irssi SILC client so
3363 that SILC specific message hilighting, colors etc is possible.
3364 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3366 Added channel mode, channel user mode, actions, notices,
3367 whois and whowas printing to the the module-formats.c.
3369 * Fixed a bug in channel deletion in the server. The channel
3370 is not left to the cache even if the channel founder auth mode
3371 is set when there are no users anymore on the channel. Affected
3372 file silcd/server.c.
3374 * The silc_net_localhost now resolves the entire hostname including
3375 the domain name. Affected file lib/silcutil/silcnet.c.
3377 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3379 * Changed the ask_passphrase client operation to be ascynchronous.
3380 It has now a completion callback and a context that the
3381 application must call after it has got the passphrase from
3382 the user. Affected files lib/silcclient/silcapi.h,
3383 lib/silcclient/protocol.c, lib/silcclient/command.c and
3386 Added SilcAskPassphrase callback that the application calls
3387 to deliver the passphrase to the library.
3389 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3390 The public key verification and especially a certificate
3391 verification is asynchronous procedure.
3393 Added new SILC_SKE_STATUS_PENDING status to indicate the
3394 request is pending and a callback will be called to finalize
3397 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3398 indicate that remote end did not send its public key (or
3399 certificate), even though we require it. Added check for this
3400 condition in the SKE. This was a security bug, now fixed.
3402 Defined new SilcSKEVerifyCbCompletion callback that is called
3403 when the verification process is completed.
3405 The affected files lib/silcske/silcske_status.h and
3406 lib/silcske/silcske.[ch].
3408 * Changed the verify_public_key client operation to be async
3409 as well. Defined SilcVerifyPublicKey callback that is used to
3410 indicate the success of the public key verification process.
3412 Changed the server and client to use the new async client
3415 * Changed the Irssi SILC client's internal scheduler to be called
3416 twice as many times as it used to be. As a result the client
3417 should be a bit faster now. Affected file is
3418 irssi/src/silc/core/silc-core.c.
3420 * Added support to Irssi SILC client of asynchronous public key
3421 verification and passphrase inquiry. Affected file is
3422 irssi/src/silc/core/silc-core.c.
3424 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3426 * Do not say "You have left channel %s" in client library.
3427 Moved it to the application. Affected files are
3428 lib/silcclient/command.c and silc/client_ops.c.
3430 * Fixed silc_client_get_clients. Command context was not
3431 duplicated and was freed memory in the callback. Affected
3432 file lib/silcclient/idlist.c.
3434 * Do not say "you are now talking..." on JOIN command in the
3435 client library. The appliation must handle it.
3437 * Do not say ".. changed topic to" in command reply in the
3438 client libary. The application must handle it.
3440 * Fixed TOPIC command sending in the client library.
3442 * Fixed a memory leak in silc_client_command_free in the file
3443 lib/silcclient/command.c.
3445 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * Imported a modified version of Irssi client to the source tree.
3448 The Irssi will be used to create a new client called
3449 Irssi SILC. Imported to irssi/.
3451 Added silc_core_init_finish function to the Irssi. Affected
3452 file irssi/configure.in.
3454 A lot changes in the Makefile.ams around the irssi tree.
3456 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3458 * Do not rehash if the new size is same as the old size of the
3459 hash table, in the silc_hash_table_rehash*. The affected file
3460 lib/silcutil/silchashtable.c.
3462 * Replaced hash_table_del_by_context calls from the server
3463 (when channel->user_list and client->channels) to the
3464 hash_table_del as it is sufficient and faster.
3466 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3468 * Added silc_hash_table_list, silc_hash_table_get and the
3469 SilcHashTableList structure to provide an alternative way to
3470 traverse the hash table. The affected files are
3471 lib/silcutil/silchashtable.[ch].
3473 * Changed the server's idlist routines to use the hash table
3474 routines to optimize the code.
3476 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3478 * Replaced the client entry's `channel' list and channel entry's
3479 `user_list' list to hash tables for optimized lookup. Changed
3480 the code to use the hash table interface around the code.
3481 Affected file lib/silcd/idlist.[ch].
3483 * Added `auto_rehash' boolean argument to the function
3484 silc_hash_table_alloc to indicate whether the hash table should
3485 auto-rehash when it thinks is appropriate time. It will
3486 increase the hash table size if the there is twice as much
3487 entries in the table than the size of the table, and will
3488 decrease the size if there are twice as less entries than
3489 the size of the table.
3491 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3493 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3495 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3497 * silc_idcache_purge_by_context deletes the entry now by context
3498 as it is supposed to do. Affected file lib/silccore/idcache.c.
3500 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3501 client is not anymore valid (WHOWAS givens the info) and not
3502 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3504 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3506 * Removed the `data' and `data_len' arguments from the ID Cache
3507 interfaces and added `name' argument. ID Cache does not handle
3508 anymore the binary data only a names associated with given ID.
3510 * When hashing a Client ID with silc_hash_id the entire ID is
3511 not hashed anymore, instead only the hash of the Client ID is
3512 hashed. This way we can access the Client ID from the cache
3513 with Client ID but with the hash of the ID (which is a hash of
3514 the nickname) as well without any difference in performance.
3516 Added also silc_idcache_find_by_id_one_ext to do one on one
3517 searching when we have the actual ID. Added also function
3518 silc_hash_client_id_compare. The affected files are
3519 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3521 * When hashing the name associated with a ID it is always done
3522 in lowercase. This way we can access the cache without worrying
3523 about case-sensitivity, even though, for example nicknames are
3526 * Fixed a bug in server with channel message sending. It put
3527 wrong ID type as destination ID. The affected file
3528 silcd/packet_send.c.
3530 * silc_idcache_del_by_context now deletes from all hash tables
3531 by context. Affected file lib/silccore/idcache.c.
3533 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3535 * Changed the client library to use the new ID Cache interface.
3536 Changes around the source tree.
3538 * Added silc_hash_table_rehash_ext to rehash with specific
3539 hash function. Affected file lib/silcutil/silchashtable.[ch].
3541 * Added silc_hash_string_compare to compare two strings in the
3542 hash table. Affected file lib/silcutil/silcutil.[ch].
3544 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3546 * Added new function silc_idcache_del_by_context into the
3547 lib/silccore/idcache.[ch].
3549 * Changed the server's ID list routines to use the new ID Cache
3550 interface. Changes around the source tree.
3552 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3554 * Added silc_hash_table_del[_by_context]_ext functions in to the
3555 lib/silcutil/silchashtable.[ch].
3557 Removed silc_hash_table_find_all* routines and added new
3558 silc_hash_table_find_foreach to replace them.
3560 Added silc_hash_table_replace_ext function as extended
3561 replacing function. Separated the simple hash table interface
3562 from the extended hash table interface in the file
3563 lib/silcutil/silchashtable.h.
3565 * Fixed minor bugs and changed it to use some of the new
3566 hash table functions in lib/silccore/idcache.c
3568 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3570 * Added new function silc_hash_table_find_all to return all keys
3571 in the hash table by the specified key. As the hash table is
3572 collision resistant it also makes it possible to have several
3573 duplicate keys in the hash table. This function may be used to
3574 find all of the keys from the hash.
3576 Added user_context arguments to the SilcHashFunction,
3577 SilcHashCompare and SilcHashDestructor to deliver user specified
3580 Added new fuctions silc_hash_table_find[_all]_ext to do
3581 extended lookup with specified hash and compare functions and
3582 specified user contexts.
3584 Added new function silc_hash_table_add_ext to add the key
3585 with specified hash function and user context.
3587 Added new function silc_hash_table_foreach to traverse all
3588 entrys in the hash table. Added SilcHashForeach callback
3591 Added new function silc_hash_table_del_by_context to delete
3592 the entry only if the context associated with the key matches.
3594 Affected files are lib/silcutil/silchashtable.[ch].
3596 * Removed silc_hash_[server/client/channel]_id and added just
3597 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3598 silc_hash_id_compare to compare two ID's using as the hash table
3599 comparison function. Added also silc_hash_data to hash
3600 binary data and silc_hash_data_compare to compare it.
3602 * Removed silc_idlist_find_client_by_hash as it is not needed
3603 anymore. Affected file silcd/idlist.[ch].
3605 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3606 to use internally the SilcHashTable. The new ID Cache is a lot
3607 faster than the old one. Some of the ID Cache interface was also
3608 rewritten and obsolete and stupid functions were removed.
3610 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3612 * Added entry_count field to the SilcHashTable to keep the number
3613 of the entries in the table. Implemented the function
3614 silc_hash_table_rehash. Added new function
3615 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3617 Fixed a minor bug in silc_hash_table_free.
3619 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3620 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3621 into the lib/silcutil/silcutil.[ch].
3623 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * Implemented a collision resistant hash table into the
3626 lib/silcutil/silchashtable[ch]. See the header and the source
3627 for the SilcHashTable API.
3629 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3631 * Merged dotconf version 1.0.2 into lib/dotconf.
3633 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3635 * Do not compile anything in lib/silcsim/* if the SIM support
3636 is not enabled. The tree should now compile without problems
3639 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3641 * Compiled the SILC under cygwin. Compiled and tested briefly
3642 without problems. More tests needed. The SIMs didn't compile
3645 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3647 * Fixed possible crash in silc_get_username in the
3648 lib/silcutil/silcutil.c.
3650 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Fixed a va_arg in silc/client_ops.c.
3654 * Oops, RC5 routines were named AES and caused some problems
3655 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3657 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3659 * Added new SilcIDIP structure into the lib/silccore/id.h and
3660 replaced the old `ip' fields from all SILC ID's to that type.
3661 This is a step towards IPv6 support.
3663 The silc_id_get_len takes now the ID as an extra argument.
3664 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3665 both IPv4 and IPv6 based ID's.
3667 The affected files are lib/silccore/id.[ch] and other files
3668 around the tree using these routines.
3670 * Removed the ID length arguments in server from various
3671 silc_server_send_notify_* routines -> they are not needed
3674 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3676 * Fixed memory leak in silc_encode_pem_file in the file
3677 lib/silcutil/silcutil.c.
3679 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3681 * Check minor version as well in the SKE. Affected files are
3682 silcd/protocol.c and lib/silcclient/protocol.c.
3684 * Added --identifier option to the server so that an identifier
3685 can be when creating the public key for the server. Affected
3686 file is silcd/silcd.c.
3688 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3689 lib/silccrypt/silcpkcs.c.
3691 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3693 * Register default ciphers and stuff when using -C option with
3694 the server. Affected file sildc/silcd.c.
3696 * Put back the servers public key filename format, it is better
3697 than the new one. For now, the client keys are saved with the
3698 new filename format. The affected file silc/client_ops.c.
3700 * Implemented the Cipher API for the rest of the ciphers that
3701 did not implement it or implemented it the wrong way.
3703 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3705 * Register default ciphers and stuff when using the -S option
3706 in the client. Affected file silc/silc.c. Same also when
3707 creating new key pair with -C option.
3709 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3711 * Fixed the silc_verify_public_key client operation function to
3712 save the public keys differently. The fingerprint is now
3713 used as filename and not the hostname. This way also the
3714 client keys are saved uniquely and not with hostnames. The
3715 affected file is silc/client_ops.c.
3717 * Trimmed the silc_hash_fingerprint function to remove extra
3718 whitespaces from the end of the fingerprint. The affected
3719 file is lib/silccrypt/silchash.c.
3723 * Added silc_cipher_register_default function to register all
3724 default ciphers. It can be used when configuration files
3725 does not exist and the application does not want any specific
3726 ciphers in any specific order.
3728 The SilcDList is now used as silc_cipher_list dynamically
3729 allocated cipher list. Removed the static list all together
3730 and now all ciphers must be allocated to the dynamic list.
3731 The silc_cipher_alloc routine was changed to check only the
3734 All silc_cipher_* routines that used to return int returns
3737 The affected files lib/silccrypt/silccrypt.[ch].
3739 * The same thing was done to silc_hash_* as for silc_cipher_*
3740 routines. Affected files lib/silccrypt/silchash.[ch].
3742 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3743 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3744 Added also silc_pkcs_[un]register[_default] functions.
3745 Removed the data_context from the PKCS API.
3747 * Added silc_hmac_register_default function to register default
3748 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3749 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3750 to unregister all hmacs at once.
3752 * Register the default ciphers, hash functions, PKCSs and HMACs
3753 if client's configuration file does not exist. The affected
3756 * The client did not load the hash functions from the SIM
3757 modules at all. Added support for this. Affected file is
3758 silc/clientconfig.c.
3760 * When decoding public key with silc_pkcs_public_key_decode, check
3761 the supported algorithm only if PKCS are registered. Affected
3762 file lib/silccrypt/silcpkcs.c. The same was done with the
3763 silc_pkcs_private_key_decode.
3765 * Fixed the SILC List routines to keep the list always in order.
3766 It used to change the list's order when traversing the list but
3767 not it preserves the order. Affected file lib/trq/silclist.h.
3769 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3771 * Added the client library to use the SilcSocketConnection's
3772 reference counter (by silc_socket_dup) to prevent the bug that
3773 the socket object may be freed underneath async operation.
3775 * The name resolv library checking fixes in the configure.in.pre.
3778 * Created new version of the protocol drafts for future
3779 development. The -03 drafts are the ones that will be changed
3780 in the trunk now and the -02 will remain as they are.
3782 * Send list of CUMODE notifys to the router when announcing
3783 the channel users to the router. Affected file silcd/server.c.
3784 If the router receiving channel founder CUMODE for a channel
3785 that already has channel founder it will send CUMODE notify
3786 to the sender to remove the channel founder rights from the
3787 announced client. Affected file silcd/packet_receive.c.
3789 * The CUMODE notify may now use Server ID as well as the entity
3790 who changes the mode. Updated protocool specs.
3792 * Updated INSTALL and README files.
3794 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3796 * New web pages in the http://silc.pspt.fi. The pages was
3801 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3803 * Implemented the [DenyConnectin] config section in the server.
3804 Added silc_server_config_denied_conn to check whether incoming
3805 connection is denied. Affected file silcd/serverconfig.[ch].
3807 * Do not check the ports when checking the incoming configuration
3808 data if the port is 0, meaning any. Affected file is
3809 silcd/serverconfig.c.
3811 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3813 * Fixed buffer overflow in silc_string_compare in the file
3814 lib/silcutil/silcutil.c.
3816 * Fixed double free in silc_server_command_leave in the file
3819 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Fixed the version checking in the server. Affected file is
3824 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3826 * Fixed the configuration data fetching when accepting new
3827 connections in the server. Affected file silcd/server.c.
3829 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3831 * Added `sender_entry' argument to the function
3832 silc_server_packet_relay_to_channel so that we can check
3833 whether some destination actually belongs to the same route
3834 the sender belongs (ie, we must not resend the packet to the
3835 sender). Affected file silcd/packet_send.[ch].
3837 * Added `servername' field to the SilcClientEntry in the server
3838 to hold the name of the server where client is from. Affected
3839 file is silcd/idlist.h.
3841 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3843 * Moved the channel message encrypting in the router betwen
3844 router connections from silc_server_channel_message to the
3845 silc_server_packet_relay_to_channel since we want to check
3846 whether we have anybody channel before encrypting anything.
3847 Affected files silcd/packet_[receive/send].c.
3849 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3851 * Fixed the [AdminConnection] server config section to support
3852 multiple entries. Affected file silcd/serverconfig.c.
3854 * Added support into the server to check the validity of the
3855 incoming connection before executing any KE or authentication
3858 * The connection configuration is now saved to the KE and
3859 connection auth protocol contexts and not fetched anymore in
3860 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3862 * The local hosts listenning address and port is also resolved
3863 now when starting the server. We want to have the socket object
3864 to include the real address and port for the listener. Added
3865 new function silc_net_check_local_by_sock into the files
3866 lib/silcutil/silcnet.[ch].
3868 * Fixed a broadcast bug in server -> do not broadcast if we
3871 * Fixed a routing bug. Do not route broadcast packets ever.
3872 Broadcast packets must be processed always and not routed since
3873 they may be destined to some other host than yourself and thus
3874 would get routed without no good reason. Affected file is
3877 * Added function silc_server_config_is_primary_route to check
3878 whether primary router connection has been configured (a router
3879 configuration that we are initiating). If there is not, we
3880 will assume that there is only two routers in the SILC network
3881 and we will use the incoming router connection as our primary
3882 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3884 * Changed the order of the broadcasting. Broadcast _after_ the
3885 packet has been processed not before. Affected file is
3888 * Fixed a [ClientConnection] parsing bug. The port was never
3889 parsed correctly thus resulting to port 0. Affected file
3890 silcd/serverconfig.c.
3892 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3893 argument and did not set the broadcast packet flag. Affected
3894 file silcd/packet_send.c. Fixed same bug in the function
3895 silc_server_send_notify as well.
3897 * If we receive NEW_ID packet for our own ID in the server, ignore
3900 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3904 * Removed the nickname from the Private Message Payload.
3905 Updated the code and the protocol specs.
3907 * Updated protocol specs for submitting to the IETF.
3909 * Tweaked the Random Number Generator a bit. Affected file
3910 lib/silccrypt/silcrng.c. Exported a new function
3911 silc_rng_[global]_add_noise which can be used to add more
3914 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3916 * Do not parse packets with different timeout when protocol
3917 is active -> may cause problem with rekey. Affected file
3920 * When server receives signoff notify it must not create
3921 new channel key if the client is on any channels since the
3922 sender of the signoff notify will create it.
3924 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3926 * Added printing of error messages during SKE protocol from the
3927 failure packet sent by server during SKE. Affected file
3930 * Removed the client's failure_callback handling with timeout
3931 and handle it immediately when received.
3933 * The SKE library returned wrong type in SUCCESS and FAILURE
3934 packets. They must be 32 bit MSB not 16 bit MSB.
3936 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3938 * Ok, rewrote the logic of the re-key and now it seems to work.
3939 I tested it on high traffic with frequent re-keys without
3940 problems. Added hmac_receive (and renamed hmac to hmac_send)
3941 in SilcClientConnection in lib/silcclient/client.h and
3942 in SilcIDListData in silcd/idlist.h. Also, removed the
3943 SilcPacketParserContext's cipher and hmac fields as they are
3944 not needed anymore and actually caused some problems when
3945 the ciphers and hmac's changed underneath the packet parser.
3947 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3949 * If re-key protocol is active then process the incoming packets
3950 synchronously since we must assure that icoming packets encrypted
3951 with the old key is processed before the new keys is set to
3952 use. This is true other packets than for REKEY packets.
3953 Affected file silcd/server.c. The same was done to client library
3954 as well, affected file lib/silcclient/client.c.
3956 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3958 * Fixed bug in client and server to accept the force send if
3959 the packet is send from silc_[server/client]_packet_process
3960 function. Otherwise the packets are never delivered, oops.
3962 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3964 * Disable force sending of packets when REKEY protocol is active.
3965 We must assure that no packet is sent directly when rekey is
3966 performed. All packets must be sent through packet queue.
3967 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3968 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3969 function is silc_[server/client]_packet_send_real to check
3972 * Replaced the SIM paths from example config files to
3973 /usr/local/modules. Also, make install creates now
3974 /usr/local/silc/logs directory to hold all the SILC server
3977 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * Made the configure.in.pre work on Solaris. Patch by salo.
3981 * Made all ciphers compatible with non-x86 machines. Defined
3982 CBC mode macros into lib/silccrypt/ciphers_def.h.
3984 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3986 * Fixed the make install.
3988 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3990 * When MAC computation fails the silc_packet_decrypt returned 0
3991 even though it was supposed to return -1. Fixed this. The
3992 affected file is lib/silccore/silcpacket.c.
3994 * Do not replace the config files in /etc/silc (in make install)
3995 if they already exist. Affected file ./Makefile.am.
3997 * Do not send re-key packets immediately but through packet queue.
3998 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4000 * Changed silc_net_check_host_by_sock to return FALSE if the
4001 IP/DNS could not be resolved. Though, it returns the IP address
4002 now even if it could not resolve it (but returns also FALSE).
4003 Affected file lib/silcutil/silcnet.[ch].
4005 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4007 * Added silc_pkcs_decode_identifier to decode the public key's
4008 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4009 Added also silc_pkcs_free_identifier. Added also new context
4010 SilcPublicKeyIdentifier.
4012 * Added -S option to the silc client. It is used to dump the
4013 contents of the specified public key file.
4015 * Changed the PKCS api to return the public key length when
4016 setting the public key.
4018 * Fixed a fatal bug in the public and private key file loading.
4019 Affected file lib/silccrypt/silcpkcs.c.
4021 * Execute the packet parsing for client with zero (0) timeout
4022 if the protocol is active. Affected file silcd/server.c.
4024 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4026 * Made the key generation options to the silcd program. Added
4027 -C option, equivalent to client's option.
4029 * Added new [ServerKeys] config section to the server. It
4030 configures the server's public and private key.
4032 * Defined generic Public Key Payload into the protocol
4033 specification to send specific type of public keys and
4036 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4037 public key or certificate.
4039 * Implemented the GETKEY command to the server and to the
4040 client library and on user interface.
4042 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4044 * Made preliminary `make install' work.
4046 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Added SilcServerRekey context into silcd/idlist.h.
4050 * Added the PFS support as defined in the specification to the
4051 SKE protocol. Affected files lib/silcske/*.c.
4053 * Added `ske_group' field to the SilcServerRekey context to hold
4054 the number of the SKE group that is used with PFS in re-key.
4055 Affected file silcd/idlist.h.
4057 * Added PFS re-key support to the server. Affected file is
4060 * Added silc_protocol_cancel to cancel execution of the next
4061 state of the protocol. Affected file is
4062 lib/silccore/silcprotocol.[ch].
4064 * Added the re-key support with and without PFS to the client
4065 library. Re-key is performed once in an hour, by default.
4067 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4068 Added silc_client_rekey_callback and silc_client_rekey_final.
4069 Affected files are lib/silcclient/protocol.[ch] and
4070 lib/silcclient/client.[ch].
4072 * Removed the `hmac_key' and `hmac_key_len' fields from the
4073 SilcClientConnection structure; not needed. Affected file is
4074 lib/silcclient/client.h.
4078 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4080 * Do not ask whether user wants to use the negotiated private key
4081 for private messages, just use it. Affected file is
4082 silc/local_command.c.
4084 * Added `send_enc_key' and `enc_key_len' fields to the
4085 SilcIDListData structure since they are needed in the re-key
4086 phase. Affected file is silcd/idlist.[ch].
4088 * Implemented the simple re-key protocol into the server.
4089 Affected files silcd/server.c and silcd/protocol.[ch]. The
4090 re-key will be performed once in an hour, by default.
4092 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4093 Added silc_server_rekey, silc_server_rekey_callback and
4094 silc_server_rekey_final.
4096 * Removed Tunneled flag from the protocol. Updated the code
4097 and the specifications.
4099 * Adde `pfs' field to the SilcIDListData to indicate whether
4100 the PFS is to be performed in the re-key. Affected file is
4103 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4105 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4106 int64 of at least the xintXX size. If void * is less that 4
4107 bytes uint32 * will be used. Defined bool as boolean.
4109 * Changed _ALL_ unsigned long and unsigned int to uint32,
4110 unsgined short to uint16 in the source tree.
4112 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4113 not handle clients that has entry->data.registered == FALSE.
4114 They are not in the network anymore. Affected file is
4117 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4119 * Implemented the sending of the SERVER_SIGNOFF notify in the
4120 server. Affected file is silcd/server.c.
4122 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4123 Added also silc_notify_payload_encode_args into the
4124 lib/silccore/silcnotify.[ch].
4126 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4127 Affected file silcd/packet_receive.c.
4129 * Implemented the SERVER_SIGNOFF notify handling in the client
4130 library. Affected file lib/silcclient/client_notify.c. Also,
4131 implemnted the printing of the SERVER_SIGNOFF info to the
4132 application. Affected file silc/client_ops.c.
4134 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4135 if the deleting was successful. Affected file silcd/idlist.[ch].
4137 * Added support for public key authentication in the connection
4138 authentication protocol in the client library. Affected file
4139 lib/silcclient/protocol.c.
4141 * Changed the server's silc_idlist_get_clients_by_* interface
4142 to support already allocated array so that new entries may be
4143 added to pre-allocated array. Affected file silcd/idlist.[ch].
4144 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4145 and command replies.
4147 * All command reply functions in the server now calls the
4148 pending command callback even if error occured. This way the
4149 error will be delivered to the client as well. Affected files
4150 silcd/command.c and silcd/command_reply.c.
4152 * Fixed INFO command to return local server's info if no server
4153 was provided. Affected file lib/silcclient/command.c.
4155 * Removed RESTART command for good. Updated the code and the
4158 * Rewrote parts of the task system. It is a bit simpler now.
4159 Removed unsued task priorities. The affected files are
4160 lib/silcutil/silctask.[ch].
4162 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4164 * Moved the USERS printing from the library to the application.
4165 Affected files lib/silcclient/command.c and silc/client_ops.c.
4167 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4171 * Added channel key re-key support. The re-key is perfomed
4172 only by the router and is done once in an hour. Added `rekey'
4173 field to the SilcChannelEntry in the server. Affected files
4174 silcd/server.c and silcd/idlist.h.
4176 * Added silc_task_unregister_by_context into the file
4177 lib/silcutil/silctask.[ch].
4179 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4181 * Added SILC_UMODE_GONE mode to indicate when the client is not
4182 present in the SILC network. Added also support to the local
4183 command AWAY that will set this mode. Added support of showing
4184 "xxx is gone" in WHOIS command. The USERS command shows the
4185 gone status as well.
4187 * Fixed setting server and router operator privileges in the
4188 server's UMODE command. Affected file silcd/command.c.
4190 * Merged the SKE KE1 and KE2 payloads into one payload. The
4191 new KE payload is equivalent to the old KE2 payload.
4193 Cleaned up the SKE Start Payload parsing. It now uses the
4194 simple buffer unformatting to do the parsing. A lot faster
4197 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4198 to the SKE that is used to indicate whether both of the SKE
4199 parties should perform authentication. By default only the
4200 responder performs authentication. By setting this flag also
4201 the initiator must do authentication. By default it is unset
4202 since in normal SKE case, client to server connection, only
4203 the responder should do authentication. When doing SKE between
4204 two clients both should perform authentication. Updated the
4205 code and the protocol specs.
4207 * A little fix to IDENTIFY command in the server. Search the
4208 client first by hash not nickname. Affected file is
4211 * Fixed the silc_client_close_connection to support closing
4212 the client to client connections wihtout deleting too much
4213 data. Affected file lib/silcclient/client.c.
4215 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4216 are received if protocol used to be active but is not anymore
4217 the application would crash due to NULL pointer dereference.
4218 Affected files silcd/server.c and lib/silcclient/client.c.
4220 * Added `hash' field to the SilcClientConnection to include
4221 the hash function negotiated in the SKE protocol.
4223 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4224 to set the channel founder authentication data. A client can
4225 claim the founder rights later by providing the authentication
4226 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4227 This way the channel founder can regain the channel founder
4228 privileges even it is left the channel. This works only on
4229 local server and the client must be connected to the same
4230 server to be able to regain the founder rights. Updated the
4231 protocol specs accordingly.
4233 Added support to the CMODE command in the client to set the
4234 founder auth data. Read the README to see how to set it.
4236 Added support to the CUMODE command to claim the founder
4237 rights. Read the README to see how to do it.
4239 Added support for the founder authentication to the Channel
4240 Entry in the server. Affected file silcd/idlist.h.
4242 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4243 server's CMODE command. Affected file silcd/command.c.
4245 * Added the following new functions into lib/silccore/silcauth.[ch]:
4246 silc_auth_get_method and silc_auth_get_data.
4248 * The server now saves the remote hosts public key to the
4249 SilcIDListData pointer. Affected file silcd/protocol.c.
4251 * The normal server now does not remove the channel entry from
4252 the cache if the founder authentication data is set. It used
4253 to remove it if the founder was the last one on the channel on
4254 the server and left the channel. The auth data is saved and
4255 if the channel is re-joined later the old entry is used with
4256 the old auth data. Affected files silcd/command_reply.c and
4259 * Removed the `pkcs' field from the SilcIDListData structure
4260 in the server; it is not used. Affected file silcd/idlist.h.
4262 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4264 * Fixed packet processing on slow links. Partial packets were
4265 never re-processed because the incoming data buffer was cleared
4266 by the application. Application must not directly clear the
4267 sock->inbuf, the packet processing routines handle it. Fixed
4268 this in client library and in server.
4270 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4272 * Fixed the WHOIS and IDENTIFY send reply function to really
4273 check whether to send list or just one entry. Affected file
4276 * Cleaned up the LEAVE command's channel key distribution. The
4277 affected file silcd/command.c.
4279 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4280 can enforce the channel mode as well. In that case the ID
4281 includes the ID of the server. The code now enforces the
4282 mode change if the router have different mode than the server.
4284 * The notify client operation with CMODE_CHANGE notify can now
4285 return NULL client_entry pointer if the CMODE was not changed
4286 by client. Application must check for this.
4288 * Added <Server ID> argument to INFO command to support server
4289 info fetching by Server ID.
4291 * Added silc_server_announce_get_channel_users to get assembled
4292 packets of channel users of the specified channel. Affected
4293 file silcd/server.[ch].
4295 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4296 was freed underneath the ID Cache.
4298 * Re-announce clients when the server received CHANNEL_CHANGE
4299 notify from the router. Affected file silcd/packet_send.c.
4301 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4303 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4304 crashed since it did not handle the fact that there is no cipher
4305 called "3" and didn't check the error condition. Now fixed.
4307 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4308 flag. It can be used to send message requests.
4310 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4312 * Implemented the RESTART command in the client.
4314 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4315 notice type messages. Added notice printing to the user
4318 * The channel keys are not re-generated if the channel's mode
4319 is PRIVKEY, ie private key on the channel exists. Affected
4320 files silcd/server.c and silcd/command.c.
4322 * Fixed a little bug in channel message delivery when channel
4323 private keys are set in the server. Affected file is
4324 silcd/packet_send.c.
4326 * Changed the setting on channel->on_channel = TRUE from the
4327 silc_client_save_channel_key to the JOIN command reply. The
4328 key payload is not received if the private channel key is set.
4329 Affected file lib/silcclient/command_reply.c and the
4330 lib/silcclient/client_channel.c.
4332 * When the CMODE_CHANGE notify is sent and the channel private
4333 key mode is removed the channel key must be re-generated in
4334 other cells as well. Added this support for the router in the
4335 silcd/packet_receive.c.
4337 * Added new local command NOTICE to send notice message on
4338 channel. Affected file silc/local_command.[ch].
4340 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4342 * Added new local command ME to the client. It is used to send
4343 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4344 some action. Affected file silc/local_command.[ch].
4346 * Changed channel_message and private_message client operations
4347 to deliver the message flags to the application. Added also
4348 the `flags' arguments to the silc_client_send_channel_message
4349 and silc_client_send_private_message functions. Affected file
4352 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4354 * Redefined the Private Message Payload to support private message
4355 keys and to support the new private message flags. Updated
4356 the protocol specs. Flags makes it possible to have for example
4357 CTCP style messages.
4359 * Added new type SilcPrivateMessagePayload and defined an API
4360 for it in the lib/silcclient/silcprivate.[ch].
4362 * Tested private message private keys successfully. Tested the
4363 private message key set, unset and list commands with the new
4366 * Redefined the Channel Message Payload to include the channel
4367 message flags (equal with private message flags) to support
4368 for example CTCP style messages.
4370 * Defined some of the message (for channel and private message)
4371 flags. Updated the protocol specs and added the flags to the
4372 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4374 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4376 * Added SilcKeyAgreementStatus type to the key agreement routines
4377 to indicate the current status and error if one occured.
4378 The status types are defined in the lib/silcclient/silcapi.h.
4380 * Added new local command KEY that is used to set and unset private
4381 keys for channels, set and unset private keys for private messages
4382 with remote clients and to send key agreement requests and
4383 negotiate the key agreement protocol with remote client. The
4384 key agreement is supported only to negotiate private message keys,
4385 it currently cannot be used to negotiate private keys for channels,
4386 as it is not convenient for that purpose.
4388 * Fixed a minor pending callback setting bug in the function
4389 silc_client_get_client_by_id_resolve, now the function works.
4390 Affected file lib/silcclient/idlist.c.
4392 * Added function silc_net_get_local_port to get local bound
4393 port by socket. Added to lib/silcutil/silcnet.[ch].
4395 * Added `sockets' and `sockets_count' fields to the SilcClient
4396 object. They hold the sockets of the listenning sockets in
4397 the client. Listenning sockets may be for example the key
4398 agreement server. Affected file lib/silcclient/client.[ch].
4399 Added functions the silc_client_add_socket and the
4400 silc_client_del_socket. They are exported to the application
4403 * Added ~./silc/clientkeys to support other client's public keys.
4405 * Renamed verify_server_key client operation to verify_public_key
4406 and added one argument to indicate the type of the connection
4407 (server, client etc.).
4409 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4411 * Added silc_server_connection_auth_request to handle the
4412 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4413 silcd/packet_receive.[ch].
4415 * Added silc_server_send_connection_auth_request into the
4416 silcd/packet_send.c to send the connection auth request packet.
4418 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4421 * Fixed the public key authentication in responder side in the
4422 server. The `auth_data' pointer includes the SilcPublicKey
4423 not the path to the public key. Affected file silcd/protocol.c.
4425 * Implemented the public key authentication in the initiator side
4426 in the server. Affected file silcd/protocol.c.
4428 * Removed the [RedirectClient] config section from the server
4429 configuration. Is not needed and I don't want to implement it.
4431 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Cleaned up the CMODE command in the server. It now works
4434 correctly and supports all the modes defined in the protocol.
4435 Affected file is silcd/command.c.
4437 * Added `hmac_name' field to the SilcChannelEntry in the server
4438 to hold the default HMAC of the channel. It can be set when
4439 creating the channel (with JOIN command). Affected files
4442 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4443 type to indicate the change of the current cipher and hmac
4444 on the channel. Client can safely ignore the <cipher> argument
4445 (if it chooses to do so) since the CHANNEL_KEY packet will
4446 force the channel key change anyway. The <hmac> argument is
4447 important since the client is responsible of setting the new
4448 HMAC and the hmac key into use.
4450 * Fixed the CMODE command in the client library as well.
4452 * Tested CMODE command in router environment successfully.
4454 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4456 * Show the version of the remote client (or server) when connecting
4457 to the server. It is logged to the log file. Affected file
4458 is silcd/protocol.c.
4460 * Fixed the KILLED notify handling in the client library. The
4461 client must be removed from all channels when receiving the
4464 Also, do not remove the client entry when giving the KILL
4465 command but when the KILLED notify is received.
4467 * Removed silc_idlist_find_client_by_nickname from the server.
4468 Not needed anymore. Affected files silcd/idlist.[ch].
4470 * Implemented the CHANNEL_CHANGE notify type handling to the
4471 server. Affected file silcd/server.c.
4475 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4477 * Added silc_server_send_notify_invite to send the INVITE
4478 notify between routers.
4480 * Implemented the INVITE command correctly to the server.
4482 * Implemented the INVITE notify type handling in the server.
4484 * Implemented the INVITE command to the client library and on the
4487 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4489 * Added function silc_server_get_client_resolve to find the
4490 client entry by ID from all ID lists and then resolve it
4491 (using WHOIS) if it cannot be found. Affected file is
4494 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4496 * Implemented the BAN command to the client library.
4498 * The JOIN command in the server now checks the invite list
4501 * Changed the silc_command_reply_payload_encode_va and the
4502 silc_command_payload_encode_va to support that if argument is
4503 NULL it ignores and checks the next argument. Affected file
4504 lib/silccore/silccommand.c.
4506 * Added silc_server_send_notify_ban to send the BAN notify
4507 type between routers.
4509 * Chaned the silc_notify_payload_encode to support that if
4510 argument is NULL it ignores and checks the next argument.
4511 Affected file lib/silccore/silcnotify.c.
4513 * Tested ban lists in router environment successfully.
4515 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * Implemented BAN command to the server, in silcd/command.[ch].
4519 * Removed the BAN and INVITE_LIST modes from the CMODE command
4522 * Added function silc_string_match to regex match two strings.
4523 Affected files lib/silcutil/silcutil.[ch].
4525 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4527 * Redefined parts of the SilcChannelEntry in the server to support
4528 the new ban and invite lists.
4530 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Redefined the INVITE command. The same command can be used to
4533 invite individuals to the channel but also to manage the invite
4534 list of the channel (to add to and remove from the invite list).
4535 Updated the protocol specs.
4537 * Added new command SILC_COMMAND_BAN that can be used to manage
4538 the ban list of the channel. Updated the protocol specs.
4540 * Removed the channel modes: the SILC_CMODE_BAN and the
4541 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4542 in the CMODE command. The equivalent features are now available
4543 using INVITE and BAN commands. Updated the protocol specs.
4545 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4546 in the network about change in the current ban list. The notify
4547 type is not used by the client.
4549 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4550 support the invite lists.
4552 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Added new function silc_string_regexify that converts string
4555 including wildcard characters into regex string that can
4556 be used by the GNU regex library. Added into the file
4557 lib/silcutil/silcutil.[ch].
4559 Added silc_string_regex_combine to combine to regex strings
4560 into one so that they can be used as one regex string by
4561 the GNU regex library. Added into the file
4562 lib/silcutil/silcutil.[ch].
4564 Added silc_string_regex_match to match two strings. It returns
4565 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4567 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4569 * Imported GNU regex to the soruce tree into lib/contrib.
4570 Fixed some compiler warning from the regex.c.
4572 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4574 * Fixed MOTD command in the server to work in router environment.
4576 * Fixed the MOTD command in the client library to support
4577 the server argument in the command.
4579 * Added `nickname_len' argument to the silc_idlist_add_client
4580 in the server, as the `nickname' argument may be binary data
4583 * Added silc_idlist_get_channels to return all channels from
4586 * Implemented LIST command to the server. Affected file is
4589 * Implemented the LIST command to the client library and on the
4592 * Added [<user count>] argument to the LIST command reply.
4593 With private channels the user count is not shown.
4595 * Updated TODO and README.
4597 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4599 * The client entry's data.registered must be TRUE even with
4600 global client entry on global client list. The data.registered
4601 is used to check whether the client is anymore in the network,
4602 for example with WHOWAS command so it must be valid.
4604 * Fixed the WHOWAS command in the server. It now actually works
4605 in router environment. Added function into silcd/command_reply.c
4606 silc_server_command_reply_whowas_save.
4608 * Added silc_idlist_purge function to the silcd/idlist.c
4609 to periodically purge the ID Cache.
4611 * Fixed INFO command in the server. It works now in router
4612 environment. Added <server name> argument to the INFO command
4613 reply. Updated the protocol specs.
4615 * Fixed minor bug in silc_idcache_purge to not purge if the
4616 expire value is zero.
4618 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4619 they were buggy because of the WHOWAS information.
4621 * Fixed local command MSG to handle the async resolving of
4622 the remote client properly. It used to fail the first MSG.
4623 Affected file silc/local_command.c.
4625 * Added `data_len' field to SilcIDCache context.
4627 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4629 * Update TODO. Todo in commands in the server.
4631 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4634 used by routers as broadcast packet to inform other routers
4635 about the changed user mode.
4637 Implemented the notify handling in the server. Affected file is
4638 silcd/packet_receive.c. Added the function
4639 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4641 * Added new generic Channel Payload and deprecated the New Channel
4642 Payload. The New Channel Payload is now the generic Channel
4645 * Added new argument `mode' to the silc_server_send_new_channel
4646 as it is required in the Channel Payload now.
4648 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4649 and created a new and real SilChannelPayload to represent the
4650 new generic Channel Payload. Implemented the encode/decode
4651 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4653 * Added silc_server_get_client_channel_list to return the list
4654 of channels the client has joined for WHOIS command reply.
4655 Affected file silcd/server.[ch].
4657 * Implemented the channel list sending in the WHOIS command reply
4658 in server and in the client.
4660 Implemented the channel list displaying on the user interface
4661 as well. Affected file silc/client_ops.c.
4663 * Added silc_channel_payload_parse_list to parse list of Channel
4664 Payloads. It returns SilcDList list of SilcChannelPayloads.
4665 Client for example can use this function to parse the list of
4666 channels it receives in the WHOIS command reply. The caller
4667 must free the list by calling silc_channel_payload_list_free.
4668 Affected files lib/silccore/silcchannel.[ch].
4670 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4672 * Added one new argument <user mode> to the WHOIS command reply
4673 to return the mode of the user in SILC. Updated the protocol
4676 Implemented it to the server and client.
4678 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4680 * Fixed the mode printing on the user interface on joining.
4681 Affected file silc/client_ops.c.
4683 * Implemented the UMODE command and user modes in general to the
4684 client library and to the user interface.
4686 * Implemented the UMODE command to the server.
4688 * The server now sends UNKNOWN_COMMAND error status if client sends
4689 unknown command. Affected file silcd/command.c.
4691 * All server commands now handle the command identifier the right
4692 way when sending the command reply to the client. The client can
4693 use to identify the command replies with the identifier.
4695 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4697 * Added silc_server_get_client_route to resolve the route to
4698 the client indicated by the client ID. Affected file is
4701 * Added silc_server_relay_packet as general function to relay
4702 packet to arbitrary destination. This deprecates functions
4703 like _send_private_message_key, _relay_notify etc. Affected
4704 file is silcd/packet_send.[ch].
4706 Removed silc_server_send_key_agreement,
4707 silc_server_send_private_message_key and
4708 silc_server_packet_relay_notify functions from the file
4709 silcd/packet_send.[ch].
4713 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4714 server. Affected file silcd/packet_receive.[ch].
4716 * Implemented the KILL command to the client. Implemented the
4717 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4718 Affected files lib/silcclient/command[_reply].c and
4719 lib/silcclient/client_notify.c. Implemented the KILL notify
4720 printing in the user inteface.
4722 * Fixed a lot silc_parse_nick memory leaks from the client
4723 library in the file lib/silcclient/command.c.
4725 * Changed the silc_server_send_notify_on_channels's `sender'
4726 argument from SilcSocketConnection to SilcClientEntry to
4727 check the sender as entry and not as connection object and not
4728 to send to the client provided as argument. The affected file
4729 is silcd/packet_send.[ch].
4731 * The notify packets that are destined directly to the client used
4732 to not to be processed by the server. Now changed that and the
4733 server processes all notify packets. After relaying the packet
4734 to the client the notify packet is processed in the server.
4736 * The silc_server_free_client_data now checks whether there is
4737 pending outgoing traffic for the client and purges the data to
4738 the network before removing the client entry.
4740 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4742 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4743 an client is killed from the SILC Network. Updated the protocol
4746 Added new function silc_server_send_notify_killed to the
4747 silcd/packet_send.[ch].
4749 * Added function silc_server_packet_relay_notify to relay notify
4750 packets that are destined directly to a client. In this case
4751 the server does not process the notify packets but merely relays
4752 it to the client. Affected file silcd/packet_send.[ch].
4754 Added also silc_server_packet_process_relay_notify to check
4755 whereto relay the notify. Affected file is
4756 silcd/packet_receive.[ch].
4758 * Implemented the KILL command to the server.
4762 * Added the backup schema desgined last fall to the protocol
4763 specs for everyone to see. The specification is in the
4764 *-spec-xx.txt draft and the packet type definitions for the
4765 backup routers is in *-pp-xx.txt draft. Thusly, added also
4766 new packet type SILC_PACKET_CELL_ROUTERS.
4768 * A big security problem in the implementation discovered. The
4769 signoff of an client did not cause new channel key generation
4770 which it of course should've done. The channel keys must be
4771 always re-generated when client leaves (or signoffs) the channel.
4772 The silc_server_remove_from_channels funtion now handles
4773 the channel key re-generation.
4775 * Added `sender' argument to the silc_server_send_notify_on_channels
4776 to not to send the client provided as argument. Affected file
4777 silcd/packet_send.[ch].
4779 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4781 * Implemented OPER and SILCOPER commands into the server and
4784 * Added silc_auth_verify and silc_auth_verify_data to verify
4785 the authentication directly from the authentication payload.
4786 It supports verifying both passphrase and public key based
4787 authentication. Affected file lib/silccore/silcauth.[ch].
4789 * Added `hash' field to the SilcIDListData structure. It is the
4790 hash negotiated in the SKE protocol. Affected file is
4793 * Slight redesigning of the SilcAuthPayload handling routines.
4794 Do not send SilcPKCS but SilcPublicKey as argument.
4796 * Implemented the public key authentication support to the
4797 serverconfig. The public key is loaded from the provided path
4798 and saved as authentication data to void * pointer. Thus,
4799 changed the unsigned char *auth_data to void *auth_data;
4801 * Fixed SHUTDOWN command to send the reply before the server
4802 is shutdown. :) Affected file silcd/command.c.
4804 * Fixed fatal bug in CONNECT command. The hostname was invalid
4805 memory and server crashed. Affected file silcd/command.c.
4807 * Fixed fatal bug in CLOSE command. The server_entry became
4808 invalid but was referenced later in the command. Affected file
4811 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4813 * Fixed fatal bug in failure packet handling. Server ignored
4814 the failure and thus crashed when it came.
4818 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4820 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4821 that the command may be executed only once in (about) 2 seconds.
4822 The old SILC_CF_LAG flag is same but allows command bursts up
4823 to five before limiting.
4825 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4826 server code. Various commands now includes the CF_LAG_STRICT
4827 flag to disallow any kind of miss-use of the command.
4829 * Fixed the silc_buffer_unformat to not to allocate any data
4830 if the length of the data is zero. It used to allocate the
4831 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4833 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4835 * Changed the format of AdminConnection configuration section
4836 in the server. Added username of the admin to the format.
4837 Affected files silcd/serverconfig.[ch].
4839 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4840 to return admin configuration data by host, username and/or
4843 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4845 * Implemented WHOWAS command to the server. Added the functions:
4847 silc_server_command_whowas_parse,
4848 silc_server_command_whowas_send_reply,
4849 silc_server_command_whowas_from_client and
4850 silc_server_command_whowas_from_server
4852 * Added <Client ID> argument to the WHOWAS command reply. Updated
4853 the protocol specs accordingly.
4855 * Implemented WHOWAS command and command_reply to the client
4858 Implemented the WHOWAS printing on the user interface.
4860 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4862 * Added new argument to the WHOWAS command reply, the real name.
4863 It is an optional argument. Updated the protocol specs.
4865 * Added SilcIDCacheDestructor callback that is registered when
4866 the SilcIDCache is allocated. The callback is called when
4867 an cache entry in the ID Cache expires, or is purged from the
4868 cache. Added into lib/silccore/idcache.[ch].
4870 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4871 to destruct the client entries when the cache entry expires.
4872 Other ID Cache's in server and in the client library ignores
4875 * If the ID Cache entry's `expire' field is zero then the entry
4876 never expires. Added boolean `expire' argument to the
4877 silc_idcache_add function in the lib/silccore/idcache.[ch].
4878 If it is TRUE the default expiry value is used.
4880 * Added silc_server_free_client_data_timeout that is registered
4881 when client disconnects. By default for 5 minutes we preserve
4882 the client entry for history - for WHOWAS command.
4884 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4886 * Added support to the server to enforce that commands are not
4887 executed more than once in 2 seconds. If server receives
4888 commands from client more frequently, timeout is registered
4889 to process the commands. Affected file silcd/command.c.
4890 Added new function silc_server_command_process_timeout.
4892 * Changed NICK_NOTIFY handling in client library to check that
4893 if the client's nickname was changed, so there is no need to
4894 resolve anything from the server.
4896 * Removed error printing from the WHOIS and IDENTIFY commands.
4897 If error occurs then it is ignored silently in the client library.
4898 The application, however, may map the received error to
4899 human readable error string. The application currently maps
4900 the NO_SUCH_NICKNAME error to string.
4902 * Made the command status message public to the application. Moved
4903 them from lib/silcclient/command_reply.c to
4904 lib/silcclient/command_reply.h. The application can map the
4905 received command status to the string with the
4906 silc_client_command_status_message function.
4908 * Added check to the server to check that client's ID is same
4909 as the Source ID in the packet the client sent. They must
4912 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4914 * Added dist-bzip hook to the Makefile.am to make bzip2
4915 compressed distributions.
4917 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4919 * Server now enforces the maximum length for the nickname and
4920 the channel as protocol specification dictates. 128 bytes for
4921 nickname and 256 bytes for channel name.
4923 * Moved the WHOIS printing to the application. The client libary
4924 does not print out the WHOIS information anymore, the application
4925 must do it. Renamed silc_client_command_reply_whois_print to
4926 the silc_client_command_reply_whois_save.
4928 The client's idle time is also sent to the application now, and
4929 the idle is shown on screen.
4931 * Added silc_client_command_reply_identify_save to save the
4932 received IDENTIFY entries.
4934 * Do not check for channel private keys in message sending and
4935 reception if the channel does not have the PRIVKEY mode set.
4936 Affected file lib/silclient/client_channel.c.
4938 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4940 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4941 just surfaced after chaning the JOIN procedure.
4943 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * Added silc_client_get_clients_by_list to get client entries
4946 from Client ID list, that is returned for example by JOIN
4947 and USERS command replies. The application should use this
4948 function for example when JOIN command reply is received to
4949 resolve the clients already on the channel (library does not
4950 do that anymore as USERS command reply is not used in the JOIN
4951 procedure anymore). Affected files lib/silcclient/silcapi.h and
4952 lib/silcclient/idlist.c.
4954 * JOIN command reply and USERS command reply returns now SilcBuffer
4955 pointers instead of unsigned char pointers when returning
4956 the client list and mode list.
4958 * Added <Client ID> argument to the JOIN command reply, mainly
4959 for the server to identify for which client the command was
4960 originally sent. Updated protocol specs accordingly.
4962 * Added SilcDlist private_key pointer to the SilcChannelEntry
4963 in the client to support the channel private keys. Affected
4964 file is lib/silcclient/idlist.h.
4966 * Added SilcChannelPrivateKey argument to the function
4967 silc_client_send_channel_message so that application can choose
4968 to use specific private ke if it wants to. If it is not provided,
4969 the normal channel key is used, unless private keys are set.
4970 In this case the first (key that was added first) is used
4971 as the encryption key.
4973 * Implemented the support for channel private key handling.
4974 Implemented the following functions:
4976 silc_client_add_channel_private_key,
4977 silc_client_del_channel_private_keys,
4978 silc_client_del_channel_private_key,
4979 silc_client_list_channel_private_keys and
4980 silc_client_free_channel_private_keys
4982 Affected file lib/silcclient/client_channel.c.
4984 * Added the support for the private keys in the channel message
4985 sending and encryption and in the message reception and
4986 decryption. Affected funtions are
4987 silc_client_send_channel_message and silc_client_channel_message.
4989 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4991 * Added SKE's key verify callback to the client library's
4992 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4994 * Removed the statement that server (or router) must send USERS
4995 command reply when joining to the channel so that the client
4996 knows who are on the channel. Instead, the client list and
4997 client's mode list is now sent in the JOIN command reply to the
4998 client who joined channel. This is better solution.
5000 * Added function silc_server_get_users_on_channel and function
5001 silc_server_save_users_on_channel to the silcd/server.[ch].
5003 * Removed function silc_server_command_send_users from the
5006 * Do not show topic on the client library anymore. The topic is
5007 sent in the command reply notify to the application and the
5008 application must show the topic now.
5010 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5012 * Added client searching by nickname hash into the IDENTIFY and
5013 WHOIS commands in the server as they were clearly missing from
5014 them. Affected file is silcd/command.c.
5016 * Fixed a bug in private message receiving in the client library.
5017 The remote ID was freed and it wasn't supposed, now it is
5020 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5022 * Minor fix to the channel payload; allocate the data area, as it
5023 needs to be of specific length.
5025 * If the key agreement port is zero then the operating
5026 system will define the bound port. Affected files are
5027 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5029 * Added new function silc_channel_payload_decrypt into the file
5030 lib/silccore/silcchannel.[ch].
5032 * Moved the channel message etc, check from silc_packet_decrypt
5033 to applications. The library calls now a generic
5034 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5035 when the packet is either normal or special. This was done to
5036 allow more wide range of checking that was not allowed when
5037 the code was in library. Now applications can do virtually any
5038 checks to the packet and return to the library the decision how
5039 the packet should be processed. Affected files are
5040 lib/silccore/silcpacket.[ch].
5042 Added silc_server_packet_decrypt_check to the server and
5043 silc_client_packet_decrypt_check to the client library.
5045 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5046 to send with specified source and destination information.
5048 * Channel message delivery between routers was broken after the
5049 channel key distribution was fixed earlier. The channel key
5050 was used be to distributed to other routers as well which is not
5051 allowed by the protocol. Now this is fixed and channel keys
5052 really are cell specific and the channel message delivery between
5053 routers comply with the protocol specification.
5055 * Fixed various commands in server to check also the global list
5056 for the channel entry and not just the local list. The affected
5057 file silcd/command.c.
5059 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5061 * Added assert()s to buffer formatting and unformatting routines
5062 to assert (if --enable-debug) when error occurs. Affected
5063 file: lib/silcutil/silcbuffmt.c.
5065 * Changed to auto-reconnect to check whether the remote host is
5066 router and register the re-connect timeout if it is. It used
5067 to check that whether we are normal server, but router must do
5068 auto-reconnect with another router as well. Affected file
5071 * Removed the [<key len>] option from CMODE command as the cipher
5072 name decides the key length, nowadays. See the defined ciphers
5073 from the protocol specification.
5075 * Added [<hmac>] option to the CMODE command to define the HMAC
5076 for the channel. Added SILC_CMODE_HMAC channel mode.
5078 * Added [<hmac>] option for the JOIN command so that user can
5079 select which HMAC is used to compute the MACs of the channel
5082 * Added Hmac field to the Channel Message Payload. The integrity
5083 of plaintext channel messages are now protected by computing
5084 MAC of the message and attaching the MAC to the payload. The
5085 MAC is encrypted. Now, it is clear that this causes some
5086 overhead to the size of the packet but rationale for this is that
5087 now the receiver can verify whether the channel message decrypted
5088 correctly and also when private keys are set for the channel the
5089 receiver can decrypt the packet with several keys and check from
5090 the MAC which key decrypted the message correctly.
5092 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5093 lib/silccrypt/silccipher.[ch].
5095 * Added silc_hash_len to return the digest length into the
5096 lib/silcrypt/silchash.[ch].
5098 * Rewrote parts of Silc Channel Payload interface in the
5099 lib/silccore/silcchannel.[ch]. The encode function now also
5100 encrypts the packet and parse function decrypts it.
5102 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5104 * Fixed a minor formatting bug in the SKE's key material processing.
5105 It actually might have processed the keys wrong way resulting
5108 * Redefined the mandatory HMAC algorithms and added new algorithms.
5109 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5110 and hmac-md5 truncated to 96 bits. The mandatory is now
5111 hmac-sha1-96. Rest are optional (including the one that used
5112 to be mandatory). Rationale for this is that the truncated HMAC
5113 length is sufficient from security point of view and can actually
5114 make the attack against the HMAC harder. Also, the truncated
5115 HMAC causes less overhead to the packets. See the RFC2104 for
5118 * Added new [hmac] configuration section. The SKE used to use
5119 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5120 is of course wrong. The official names that must be proposed in
5121 the SKE are the ones defined in the protocol specification
5122 (hmac-sha1-96 for example). The user can configure any hmac
5123 using any hash function configured in the [hash] section. At
5124 least, the mandatory must be configured.
5126 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5128 * Added HMAC list to the SKE proposal list. It has now both
5129 hash algorithm list and HMAC list. This makes the protocol
5130 incompatible with previous versions. The SKE now seems to work
5131 the way it is supposed to work, for the first time actually.
5133 * Defined plain Hash algorithms to the protocol specification.
5136 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5138 * Implemented support for key agreement packets into the server.
5139 Added functions silc_server_key_agreement and
5140 silc_server_send_key_agreement. Other than these functions,
5141 server has nothing to do with this packet.
5143 * Added support for private message key packets into the server.
5144 Added functions silc_server_private_message_key and
5145 silc_server_send_private_message_key.
5149 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5150 called in the protocol's final callback instead in the END
5151 protocol state. This makes a little more sense and in the same
5152 time in client we can use the same protocol routines for normal
5153 key exchange and to key agreement packet handling as well.
5155 * Added to both client's and server's KE protocol context the
5156 SilcSKEKeyMaterial pointer to save the key material. We will
5157 bring the key material to the protocol's final callback by doing
5158 this. The final callback must free the key material.
5160 * Added SKE's packet_send callback into client's KE protocol
5161 context so that the caller can choose what packet sending function
5162 is used. This way we can use different packet sending when
5163 doing normal SKE when doing key agreement packet handling (in
5164 the key agreement packet handling we do not want to encrypt
5167 * Implemented the responder side of the key agreement routines
5168 in the client. The client can now bind to specified port and
5169 accept incoming key negotiation. The key material is passed
5170 to the application after the protocol is over.
5172 * Implemented the processing of incoming Key Agreement packet
5173 in the client. Added function silc_client_key_agreement to
5176 * Implemented the intiator side of the key agreement routines
5177 in the client. The client can now initiate key agreement with
5178 another remote client. The key material is passed to the
5179 application after the protocol is over.
5181 * Created client_keyagr.c to include all the key agreement
5184 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5185 SILC_TASK_CALLBACK except that it is not static.
5187 * Created client_notify.c and moved the Notify packet handling
5188 from the client.[ch] into that file.
5190 * Created client_prvmsg.c and moved all private message and
5191 private message key routines from the client.[ch] into that file.
5193 * Create client_channel.c and moved all channel message and
5194 channel private key routines from the client.[ch] into that file.
5196 * Changed silc_client_get_client_by_id_resolve to resolve with
5197 WHOIS command instead of IDENTIFY command, in the file
5198 lib/silclient/idlist.c.
5200 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5202 * Implemented the SKE's responder side to the Client library.
5204 * When FAILURE is received to the protocol do not trust it
5205 blindly. Register a timeout to wait whether the remote closes
5206 the connection as it should do it, only after that process the
5207 actual failure. This was changed to both client and server.
5209 * Added client_internal.h to include some of the structures
5210 there instead of client.h in lib/silcclient/.
5212 * Added function silc_task_unregister_by_callback to unregister
5213 timeouts by the callback function.
5215 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5217 * Some "Incomplete WHOIS info" errors has been appearing on the
5218 log files. Took away the entry->userinfo check from WHOIS
5219 reply sending. The entry->userinfo is now " " if client did not
5220 provide one. I thought this was fixed earlier but something
5221 is wrong still. Let's see if the error still appears.
5223 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5225 * Fixed a minor bug in the login when the channel key is
5226 re-generated in the server. It used to generate the key in
5227 wrong order and thus caused problems in the channel traffic.
5229 * Fixed a minor bug in channel key distsribution after
5230 KICK command. The key was not sent to the router even though
5233 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5235 * Added silc_ske_process_key_material_data as generic routine
5236 to process any key material as the SILC protocol dictates. The
5237 function is used by the actual SKE library but can be used by
5238 applications as well. This relates to the private message keys
5239 and the channel private keys since they must be processed the
5240 same way the normal SILC session keys. The protocol dictates
5241 this. Affected files: lib/silcske/silcske.[ch].
5243 Added also silc_ske_free_key_material to free the
5244 SilcSKEKeyMaterial structure.
5246 * Defined silc_cipher_set_key function to set the key for
5247 cipher without using the object's method function. The affected
5248 files: lib/silccrypt/silccipher.[ch].
5250 * Implemented silc silc_client_add_private_message_key,
5251 silc_client_add_private_message_key_ske,
5252 silc_client_del_private_message_key,
5253 silc_client_list_private_message_keys and
5254 silc_client_free_private_message_keys functions in the
5257 Added functions silc_client_send_private_message_key to send
5258 the Private Message Key payload and silc_client_private_message_key
5259 to handle incoming Private Message Key payload.
5261 * Added Cipher field to the Private Message Key payload to set
5262 the cipher to be used. If ignored, the default cipher defined
5263 in the SILC protocol (aes-256-cbc) is used.
5265 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5267 * Removed lib/silcclient/ops.h file.
5269 Redefined parts of the SILC Client Library API. Created new
5270 file silcapi.h that deprecates the ops.h file and defines the
5271 published Client Library API. Defined also private message key
5272 API and channel private key API into the file.
5274 This is the file that the application must include from the
5275 SILC Client Library. Other files need not be included by
5276 the application anymore.
5278 * Added new key_agreement client operation callback and also
5279 defined the Key Agreement library API for the application.
5281 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5283 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5284 is used by clients to request key negotiation between another
5285 client in the SILC network. If the negotiation is started it
5286 is performed using the SKE protocol. The result of the
5287 negotiation, the secret key material, can be used for example
5288 as private message key.
5290 Implemented the Key Agreement payload into the files
5291 lib/silccore/silauth.[ch].
5293 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5295 * Redefined ciphers for the SILC protocol. Added some new ciphers
5296 and defined the key lengths for the algorithms. Changed the
5297 code accordingly. The default key length is now 256 bits.
5299 * Fixed SKE key distribution function silc_ske_process_key_material
5300 when the key length is more than 128 bits. The default key
5301 length in SILC is now 256 bits.
5303 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5304 to indicate unsupported algorithm.
5306 * Renamed rijndael.c to aes.c and all functions as well.
5308 * Fixed a long standing channel key setting bug in client library.
5309 Weird that it has never surfaced before.
5311 * Fixed bug in channel deletion. If the entire channel is removed
5312 then it must also delete the references of the channel entry
5313 from the client's channel list as the client's channel entry and
5314 the channel's client entry share same memory.
5316 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5318 * Implemented CONNECT and SHUTDOWN commands in the client.
5320 * Implemented CLOSE command to the client.
5322 * Added the function silc_idlist_find_server_by_name into the
5323 files silcd/idlist.[ch].
5325 Added the function silc_idlist_find_server_by_conn into the
5326 files silcd/idlist.[ch].
5328 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5330 * DIE command was renamed to SHUTDOWN. Updated the both code
5333 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5334 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5336 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5339 * Added function silc_server_create_connection function to create
5340 connection to remote router. My server implementation actually
5341 does not allow router to connect to normal server (it expects
5342 that normal server always initiates the connection to the router)
5343 so the CONNECT command is only good for connecting to another
5346 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5348 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5349 or some other client was kicked from the channel.
5351 Implemented the handling of the notify type to both client
5354 Implemented silc_server_send_notify_kicked to send the KICKED
5355 notify. It is used to send it to the server's primary router.
5357 * Implemented the KICK command into server and client.
5359 * Added `query' argument to the silc_idlist_get_client function
5360 to indicate whether to query the client from server or not if
5363 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5364 to indicate that the client is not channel founder.
5368 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5370 * Removed the rng context from SilcPacketContext structure and
5371 changed that the packet routine uses the Global RNG API.
5373 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5375 * Added support for quit message that client can "leave" on the
5376 channel when it quits the SILC. It is ditributed inside the
5377 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5379 Added silc_server_free_client_data that will take the
5380 signoff message as argument.
5382 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5384 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5386 * Updated parts of the protocol specification to keep it up
5389 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5391 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5392 payloads in one packet.
5394 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5395 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5396 use now the new List flag.
5398 * Also deprecated the following packet types: REPLACE_ID,
5399 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5401 * Added list support for Notify packet in server.
5403 * Added silc_server_send_notify_channel_change to send the
5404 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5405 the silc_server_send_replace_id.
5407 * Added silc_server_send_notify_nick_change to send the
5408 NICK_CHANGE notify type. Deprecates the function
5409 silc_server_send_replace_id.
5411 * Added silc_server_send_notify_join to send the JOIN notify type.
5412 Deprecates the function silc_server_send_new_channel_user.
5414 * Added silc_server_send_notify_leave to send LEAVE notify type.
5415 Deprecates the function silc_server_send_remove_channel_user.
5417 * Added silc_server_send_notify_cmode and
5418 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5419 types. Deprecates the silc_server_send_set_mode function.
5421 * Added SERVER_SIGNOFF notify type to indicate that server has
5422 quit. This means that all clients on the channel from that
5423 server will drop. This can be also used when netsplit happens.
5425 Deprecated REMOVE_ID packet type since it is not needed anymore
5428 Added silc_server_send_notify_server_signoff to send the
5429 SERVER_SIGNOFF notify type. Deprecates the function
5430 silc_server_send_remove_id.
5432 Added also silc_server_send_notify_signoff to send the
5433 SIGNOFF notify type.
5435 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5436 SILC protocol from this day on. Changed the protocol
5437 specification as well.
5439 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5440 notify type. It is used between routers to notify about
5441 topic changes on a channel.
5443 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5446 * Partly updated the protocol specification to comply with the
5447 changes now made. It is still though a bit outdated.
5449 * The JOIN notify type now takes one extra argument <Channel ID>.
5450 The packet used to be destined to the channel but now the
5451 JOIN type may be sent as list thus it is impossible to
5452 destine it to any specific channel. By adding this argument
5453 it is again possible.
5455 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Added CREDITS file. The CHANGES and CREDITS file will appear
5458 in the distribution as well.
5460 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5462 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5463 types in the server's silcd/packet_receive.c.
5465 * Implemented CMODE and CUMODE to work in router environment.
5467 * Fixed minor encoding and decoding buglet from the
5468 lib/silccore/silcmode.c.
5470 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5473 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5475 * Changed all SilcConfigServer* and silc_config_server* to
5476 SilcServerConfig* and silc_server_config*, respectively.
5479 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5481 * Associated the ID (client or server ID) to the Authentication
5482 Payload to avoid any possibility of forging. Updated the
5483 protocol specification and the code accordingly.
5485 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5487 * The RSA key length is now save to the RsaKey context in the
5488 key generation process in lib/silccrypt/rsa.c. The key length
5489 is now used to figure out the maximum size of the block allowed
5490 to be encrypted/signed.
5492 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5493 is equivalent to the silc_mp_mp2bin but does not allocate any
5496 * Changed silc_mp_mp2bin API to take length argument. If it is
5497 non-zero then the buffer is allocated that large. If zero, then
5498 the size is approximated using silc_mp_sizeinbase, which however
5501 * Created Global RNG API which is global RNG that application can
5502 initialize. After initializing, any routine anywhere in the
5503 code (including library) can use RNG without allocating a new
5504 RNG object. This was done to allow this sort of use of the
5505 RNG in code that has no chance to allocate RNG object. All
5506 applications currently allocate this and many routines in the
5507 library use this. Affected file lib/silccrypt/silcrng.[ch].
5509 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5510 it to use the Global RNG API.
5512 * Defined Authentication Payload into protocol specification that
5513 is used during SILC session to authenticate entities. It is
5514 used for example by client to authenticate itself to the server
5515 to obtain server operator privileges.
5517 Implemented this payload into the lib/silccore/silcauth.[ch].
5518 Implemented also routines for public key based authentication
5519 as the new protocol specification dictates.
5521 Moved definitions of different authentication methods from
5522 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5524 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5525 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5526 silc_pkcs_verify_with_hash functions into the file
5527 lib/silccrypt/silcpkcs.[ch].
5529 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * The client entry's userinfo pointer must be always valid.
5532 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5533 will fail since it requires the userinfo. Now, the userinfo
5534 is allocated as "" if actual userinfo does not exist. Actually,
5535 it must exist and it is totally Ok to drop client connections
5536 that does not announce the userinfo. However, we will make
5537 this workaround for now.
5539 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5540 to return the remote port by socket.
5542 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5544 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5545 SILC_SERVER_PENDING_EXEC and added an new macro
5546 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5547 data or when error occurs while processing the pending command.
5549 Added new argument `destructor' into silc_server_command_pending
5550 and to the SilcServerCommandPending object. This destructor is
5551 now called after calling the pending callback or if error occurs
5552 immediately. If error occurs the actual pending callback won't
5553 be called at all - only the destructor. The destructor may be
5554 NULL if destructor is not needed.
5556 All this applies for client library code as well. Similar
5557 changes were made there as well for the pending commands.
5559 In the client, the application must now allocate the
5560 SilcClientCommandContext with the silc_client_command_alloc
5563 * Added reference counter to the SilcServerCommandContext. Added
5564 function silc_server_command_alloc and silc_server_command_dup
5567 Same type of functions added to the client library for the same
5570 * Removed the cmd_ident from IDListData away since it is now
5571 global for all connections. It is the command identifier used
5572 in command sending and with pending commands. The affected file
5575 * Added reference counter to the SilcSocketConnection objecet to
5576 indicate the usage count of the object. The object won't be
5577 freed untill the reference counter hits zero. Currently only
5578 server uses this, and client ignores it. The client must be
5579 set to use this too later. The affected files are
5580 lib/silccore/silcsockconn.[ch]. Added also the function
5581 silc_socket_dup to increase the reference counter.
5583 This was mainly added because it is possible that the socket
5584 is removed underneath of pending command or other async
5585 operation. Now it won't be free'd and proper DISCONNECTING
5586 flags, etc. can be set to avoid sending data to connection that
5587 is not valid anymore.
5589 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5590 the connection. After that it sets SILC_SET_DISCONNECTED.
5591 It is, however, possible that the socket data is not still freed.
5592 The silc_server_packet_process now checks that data is not
5593 read or written to connection that is DISCONNECTED. The socket
5594 get's freed when the reference counter hits zero.
5596 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Changed the client operation API: channel_message operation's
5599 `sender' is now the client entry of the sender, not the nickname
5600 and the `channel' is the channel entry, not the channel name.
5602 In the private_message operation the `sender' is now also the
5603 client entry of the sender not the nickname.
5605 Affected file is lib/silcclient/ops.h and all applications
5606 using the client operations.
5608 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5610 * Moved the calling of ops->connect() from connect_to_server_final
5611 into receive_new_id functin since that is the point when the
5612 client is actually allowed to send traffic to network. The
5613 affected file is lib/silcclient/client.c.
5615 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5617 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5618 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5619 (if needs broadcasting) instead of broadcasting the packets one
5620 by one which would make a burst in the network traffic.
5622 * Added `broadcast' argument to the functions in silcd/server.[ch]
5623 silc_server_create_new_channel[_with_id] to indicate whether
5624 to send New Channel packet to primary router.
5626 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5628 * Added new function into the silcd/server.[ch] files:
5629 silc_server_create_new_channel_with_id to create new channel with
5630 already existing Channel ID.
5632 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5633 lib/silccore/silcpacket.h. This packet is used t send list of
5634 Set Mode payloads inside one packet. Server uses this to set
5635 the modes for the channels and clients on those channels, that it
5636 announced to the router when it connected to it. The protocol
5637 specification has been updated accordingly.
5639 * The silc_server_new_channel did not handle the packet coming
5640 from normal server as it normally does not send that. However,
5641 when it announces its channels it does send it. Implemented
5642 the support for that.
5644 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5645 into the file lib/silccore/id.h.
5647 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5649 * Fixed memory leaks in the functions silc_idlist_del_client,
5650 silc_idlist_del_channel and silc_idlist_del_server in the file
5651 silcd/idlist.c. All of those leaked like a sieve.
5653 * Fixed some small memory leaks in the client's function
5654 silc_client_notify_by_server.
5656 * Added functions into silcd/server.c: silc_server_announce_clients,
5657 silc_server_announce_channels and silc_server_announce_server.
5658 These functions are used by normal and router server to announce
5659 to its primary router about clients, channels and servers (when
5660 router) that we own. This is done after we've connected to the
5663 These functions effectively implements the following packet types:
5664 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5665 and SILC_PACKET_NEW_ID_LIST.
5667 * Added new functions into the silcd/packet_receive.[ch]:
5668 silc_server_new_id_list, silc_server_new_channel_list and
5669 silc_server_new_channel_user_list to handle the incoming
5670 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5672 * Added support of changing Channel ID in the function
5673 silc_server_replace_id. If the server that announces a channel
5674 to the router already exists in the router (with same name but
5675 with different Channel ID), router is responsible to send
5676 Replace ID packet to the server and force the server to change
5677 the Channel ID to the one router has.
5679 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5680 client that the Channel ID has been changed by the router. The
5681 normal server sends this to the client. Client must start using
5682 the new Channel ID as the channel's ID.
5684 Implemented handling of this new type into lib/silcclient/client.c
5685 into the function silc_client_notify_by_server.
5687 * Added new function silc_idlist_replace_channel_id into the files
5688 silcd/idlist.[ch] to replace the Channel ID.
5690 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5692 * Call silc_server_command_identify_check always when processing
5693 the IDENTIFY command in silcd/command.c
5695 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5697 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5698 send keepalive packets. The packet can be sent by clients,
5699 servers and routers.
5701 Added function silc_socket_set_heartbeat into the file
5702 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5703 If not set, the heartbeat is not performed. The actual
5704 heartbeat is implemented in the low level socket connection
5705 library. However, application is responsible of actually
5708 Added silc_server_send_heartbeat to send the actual heartbeat
5709 packet into silcd/packet_send.[ch]. Server now performs
5710 keepalive with all connections.
5712 * Added silc_task_get_first function into lib/silcutil/silctask.c
5713 to return the timeout task with shortest timeout. There was a bug
5714 in task unregistration that caused problems. TODO has been
5715 updated to include that task system must be rewritten.
5717 * The client library will now resolve the client information when
5718 receiving JOIN notify from server for client that we know but
5719 have incomplete information.
5721 * Rewrote parts of silc_server_remove_from_channels and
5722 silc_server_remove_from_one_channel as they did not remove the
5723 channel in some circumstances even though they should've.
5725 * Encryption problem encountered in server:
5727 The LEAVE command used to send the Channel Key packet to the
5728 router immediately after generating it. However, the code
5729 had earlier sent Remove Channel user packet but not immediately,
5730 ie. it was put to queue. The order of packets in the router
5731 was that Channel Key packet was first and Remove Channel User
5732 packet was second, even though they were encrypted in the
5733 reverse order. For this reason, MAC check failed. Now, this
5734 is fixed by not sending the Channel Key packet immediately but
5735 putting it to queue. However, this is more fundamental problem:
5736 packets that are in queue should actually not be encrypted
5737 because packets that are sent immediately gets encrypted
5738 actually with wrong IV (and thus MAC check fails). So, packets
5739 that are in queue should be encrypted when they are sent to
5740 the wire and not when they put to the queue.
5742 However, the problem is that the current system has not been
5743 designed to work that way. Instead, the packet is encrypted
5744 as soon as possible and left to the queue. The queue is then
5745 just purged into wire. There won't be any fixes for this
5746 any time soon. So, the current semantic for packet sending
5749 o If you send packet to remote host and do not force the send
5750 (the packet will be in queue) then all subsequent packets to the
5751 same remote host must also be put to the queue. Only after the
5752 queue has been purged is it safe again to force the packet
5755 o If you send all packets immediately then it safe to send
5756 any of subsequent packets through the queue, however, after
5757 the first packet is put to queue then any subsequent packets
5758 must also be put to the queue.
5760 Follow these rules and everything works fine.
5762 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5764 * Added new function silc_server_remove_clients_by_server to
5765 remove all client entries from ID list when the server connection
5766 is lost. In this case it is also important to invalidate all
5767 client entires as they hold the invalid server entry. This
5768 fixes fatal bug when server has lost connection and will reconnect
5771 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5773 * Made some sanity checks to silc_server_daemonise like to check
5774 whether the requested user and group actually exists.
5776 * Added sanity check to SKE's silc_ske_responder_finish to check
5777 that the public and private key actually is valid.
5779 * Invalidate the client's nickname when receiving Replace ID
5780 packet and the Client ID is being replaced. This means that the
5781 server will query the nickname if someone needs it (client)
5784 * Sort the ID Cache in client library when the ID Cache data
5785 has changed (needs sorting).
5787 * Do not allow for SILC client to create several connections to
5788 several servers. The client does not support windows right now
5789 and generating multiple connections causes weird behaviour.
5791 Irssi-silc client does support windows and can handle several
5792 connections without problems, see: www.irssi.org and SILC plugin.
5794 * Fixed some places where client was added to the IDList. The
5795 rule of thumb is following (in order to get everything right):
5796 If the client is directly connected local client then the
5797 `connection' argument must be set and `router' argument must be
5798 NULL to silc_idlist_add_client function. If the client is not
5799 directly connected client then the `router' argument must
5800 bet set and the `connection' argument must be NULL to the
5801 silc_idlist_add_client function.
5803 * The funtion silc_server_packet_send_local_channel actually did
5804 not check whether the client was locally connected or not. It
5805 does that now. Fixed a bug related to LEAVE command.
5807 * Fixed Remove Channel User payload parsing bug in server's
5808 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5810 * The server's silc_server_save_channel_key now checks also the
5811 global ID list for the channel as it might not be in the local
5812 list. Fixed a bug related to LEAVE command.
5814 * Is this the end of the [<unknown>] buglet that has been lurking
5815 around for a long time? A little for loop fix in server's
5816 silc_server_command_whois_parse that is used by both IDENTIFY
5817 and WHOIS command. At least, this was a clear bug and a cause
5818 of one type of [<unknown>] buglet.
5820 * WHOIS and IDENTIFY commands call the function
5821 silc_server_command_[whois/identify]_check function even if
5822 we are not router server.
5824 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5826 * Added --with-gmp configuration option. If set the GMP
5827 is always compiled in the SILC source tree. If not set then
5828 it is checked whether the system has the GMP3 installed. If
5829 it has then the GMP won't be compiled (the system's headers
5830 and library is used), if it doesn't have it then the GMP is
5831 compiled in the SILC source tree.
5833 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5835 * Changed RSA private exponent generation to what PKCS #1
5836 suggests. We try to find the smallest possible d by doing
5837 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5838 not security fix but optimization.
5840 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5842 * Added new config entry [Identity] to fork the server and run
5843 it as specific user and group. A patch from Bostik.
5845 * Imported Dotconf configuration library into lib/dotconf.
5846 This will be used to create the SILC configuration files later.
5847 It will appear in the distsribution after this commit.
5849 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5851 * A big code auditing weekend happening. Auditing code for
5852 obvious mistakes, bugs and errors. Also, removing any code
5855 Removed files for being obsolete:
5857 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5858 inline in the file lib/silcutil/silcbuffer.h)
5860 o lib/silcutil/silcbufutil.c (the header has inline versions)
5862 Changed code to fix possible error conditions:
5864 o The buffer formatting routines now check that the destination
5865 buffer really has enough space to add the data. This applies for
5866 both buffer formatting and unformatting
5867 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5868 unformatting was changed to accomodate following rules:
5869 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5870 sent to the function while XXX_*STRING will not allocate or copy
5871 the data into the buffer. Instead it sets the pointer from the
5872 buffer into the pointer sent as argument (XXX_*STRING used to
5873 require that the pointer must be allocated already). This change
5874 makes this whole thing a bit more consistent and more optimized
5875 (note that the data returned in the unformatting with XXX_*STRING
5876 must not be freed now). The routines return now -1 on error.
5878 o Tried to find all code that use buffer_format and buffer_unformat
5879 and added return value checking to prevent formatting and
5880 especially unformatting errors and possible subsequent fatal
5883 o Changed ske->x and ske->KEY to mallocated pointers in
5884 lib/silcske/silcske.h. Fixed possible data and memory leak.
5886 o Added return value checking to all *_parse* functions. Fixed
5887 many memory leaks as well.
5889 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5890 so that buffer overflows would not happen. All code now also
5891 checks the return value as it can fail.
5893 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5895 * Added reconnection support to server if the normal server looses
5896 its connection to the router (for example if router is rebooted).
5897 The server performs normal reconnection strategy implemented
5898 to the server. Affected file silcd/server.c.
5900 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5902 * Added new packet type SILC_PACKET_SET_MODE that is used to
5903 distribute the information about changed modes (for clients,
5904 channels and clients channel modes) to all routers in the
5905 network. Updated the protocol specification accordingly.
5907 Added functions into silcd/packet_send.c and
5908 silcd/packet_receive.c: silc_server_send_set_mode,
5909 silc_server_set_mode.
5911 Added new files silcmode.[ch] into lib/silccore that implements
5912 the encoding and decoding of Set Mode Payload. Added new type
5913 SilcSetModePayload. Moved the definitions of different modes
5914 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5916 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5918 * Oops, a little mistake in server's connection authentication
5919 protocol. The protocol is not ended with FAILURE but with
5920 SUCCESS if the authentication is Ok. :) Affected file is
5923 * Implemented NICK_CHANGE notify handling in server in the file
5924 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5925 the local clients on the channel. After the changing nickname
5926 in router environment snhould work and the [<unknown>] nickname
5927 should appear no more.
5929 The silc_server_replace_id function that receives the Replace ID
5930 payload now sends the NICK_CHANGE notify type also in the file
5931 silcd/packet_receive.c
5933 * Changed WHOIS and IDENTIFY command to support the maximum amount
5934 of arguments defined in protocol specs (3328 arguments). This
5935 fixed a bug that caused problems when there were more than three
5938 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Added extra parameter, command identifier, to the
5941 silc_client_send_command so that explicit command identifier
5944 Changed that ID list routines uses specific command identifier
5945 when sending WHOIS/IDENTIFY requests to the server so that they
5946 can be identified when the reply comes back.
5948 Affected files lib/silcclient/command.[ch],
5949 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5951 * Added `sender' argument to silc_server_packet_send_to_channel
5952 to indicaet the sender who originally sent the packet to us
5953 that we are now re-sending. Ignored if NULL. Affected file
5954 silcd/packet_send.[ch].
5956 * Added some server statistics support in silcd/server_internal.h
5957 SilcServerStatistics structure and around the server code. Also
5958 send some nice statistics information when client is connecting
5961 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5963 * Fixed channel ID decoding in server's JOIN command reply in
5964 silcd/command_reply.c
5966 * Fixed braodcasting of replace ID payload to not to send it if
5967 we are standalone server in silcd/packet_receive.c.
5969 * Fixed all channel message sending routines to not to send
5970 packets to clients that has router set, since they are routed
5971 separately in the same function earlier. Affects file
5972 silcd/packet_send.c and all channel packet sending functions.
5974 * In USERS reply, res_argv[i] are not allocated, the table
5975 is allocated. Thus changed that free the table, not its
5978 * In server's whois_check and identify_check if the client is
5979 locally connected do not send any WHOIS commands - they are not
5982 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5984 * Fixed some minor bugs in client when sending WHOIS command. The
5985 arguments was in wrong order.
5987 * Removed statis function add_to_channel from server in
5988 silcd/command.c that was previously used with the joining but
5991 * Tested USERS command in router environment successfully with two
5992 routers, two servers and two clients.
5994 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5996 * Reorganized the USERS command and command reply in client library
5997 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5998 When the command is given by user we register a pending command
5999 callback that will reprocess the command after the reply has been
6000 received from the server. When reprocessing the packet we then
6001 display the information. Thus, the USERS information is displayed
6002 now in the command callback instead of in the command reply
6003 callback. The processing of the command is same as previously
6004 when server has sent the command reply in the JOINing process.
6006 * Added to USERS command in silcd/command_reply.c to join the client,
6007 we didn't use to know about, to the channel after we've created
6008 a client entry for it. Also, for clienet we did know already still
6009 check whether it is on the channel or not and add it if not.
6011 * Removed silc_server_command_join_notify as the function and its
6014 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6016 * Changed the client's pending command handling to the same as the
6017 server's pending command handling. It is also now possible to
6018 execute command reply functions from other command reply
6019 function as the function callbacks for commands and command
6020 replies are one and same. The pending commands are not static
6021 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6022 in client connection context. Thus, pending commands are server
6023 connection specific as it is convenient.
6025 Changed the function silc_client_command_pending and
6026 silc_client_command_pending_del and added new function
6027 silc_client_command_pending_check. Removed the
6028 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6031 * Added cmd_ident, current command identifier, to the client
6032 connection context in lib/silcclient/client.h to keep track on
6033 command identifiers used in command sending. Client's command reply
6034 function handling now supports the mandatory command identifiers.
6036 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6037 funtions in client to fully support pending command callbacks.
6039 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6040 as one of the arguments to the application in the command reply
6043 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6044 before first releasing SILC but came back. Now it is removed again
6045 and should come back nomore. The FORWARDED flag was used only
6046 by the JOINing procedure by forwarding the command packet to router.
6047 Now, the JOINing procedure has been changed to more generic (due
6048 to various router environment issues) and FORWARDED is not needed
6049 anymore for anything. The protocol specification is yet to be
6052 Now, removed silc_server_packet_forward from server and the flag
6053 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6055 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6057 * Renamed NAMES command to USERS command. The NAMES was named that
6058 due to historical reasons. Now it is renamed. Also, rewrote
6059 parts of the USERS command. The nickname list is not sent anymore
6060 by the server. Only Client ID and mode lists are sent in the USERS
6061 command. Changed this also to the protocol specification.
6063 The client now resolves the names and stuff after it receives
6064 the USERS list from the server when joining to the channel.
6066 * WHOIS and IDENTIFY commands has been changed to support multiple
6067 Client ID's per command. One can now search for multiple users
6068 in the network by sending only one WHOIS or IDENTIFY command.
6069 Changed the code and the protocol specifications.
6071 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6072 uses silc_server_command_whois_parse to parse the request. */
6074 * If normal server, do not parse the WHOIS and IDENTIFY requests
6075 before sending it to the router. Saves some time.
6077 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6079 * Fixed JOIN command on client library. Wrong number of arguments
6080 used to crash the client.
6082 * Added silc_server_channel_has_global function to check whether
6083 channel has global users or not.
6085 * Added silc_server_channel_has_local function to check whether channel
6086 has locally connected clients on the channel.
6088 * The silc_server_remove_from_one_channel now checks whether the
6089 channel has global users or not after given client was removed from
6090 the channel. It also checks whether the channel has local clients
6091 on the channel anymore. If it does not have then the channel entry
6092 is removed as it is not needed anymore.
6094 * The silc_server_notify now checks on JOIN notify whether the joining
6095 client is one of locally connected or global. If it is global then
6096 the channel has now global users on the channel and that is marked
6097 to the channel entry. Also, it now saves the global client to
6098 global list who is joining and JOINs it to the channel. This is
6099 for normal server, that is.
6101 Changed silc_server_send_notify_on_channel,
6102 silc_server_packet_relay_to_channel and
6103 silc_server_packet_send_to_channel check if we are normal server
6104 and client has router set (ie. global client) do not send the
6105 message to that client, as it is already routed to our router.
6107 * Implemented LEAVE notify type handling in silc_server_notify
6110 * Tested LEAVE command in router environment successfully. Tested
6111 with two routers, two servers and two clients.
6115 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6117 * Implemented SIGNOFF notify type handling in silc_server_notify
6120 * silc_server_remove_id now removes the client entry from all channels
6121 it has joined and thusly sends SIGNOFF notify type.
6123 * Rewrote the NAMES list generation in server by removing two excess
6124 loops. The lists are created now inside one loop.
6126 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6128 * silc_server_remove_channel_user checks now also global list
6129 for channel and client.
6131 * silc_server_new_channel_user checks now both local and global
6132 list for channel and client. Fixed a bug in client id decoding.
6133 Used to decode wrong buffer.
6135 * silc_server_channel_message checks now both local and global
6136 list for channel entry.
6138 * Tested channel joining (hence JOIN) in router environment
6139 successfully. Tested with two routers, two servers and two
6142 * Tested channel message sending in router environment successfully.
6144 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6146 * Added silc_server_save_channel_key into server.[ch] to save the
6147 received channel key in Channel Key payload processing. It is
6148 also used in JOIN command reply handling.
6150 Equivalent function silc_client_save_channel_key added into
6151 client.[ch] into client library.
6153 * Changed JOIN command reply to send information whether the channel
6154 was created or not (is existing already) and the channel key
6155 payload. Changed protocol specs accordingly.
6157 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6158 the request was sent by ID and not by nickname. Crashed on
6161 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6163 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6164 now correctly save the received data.
6166 * silc_server_free_sock_user_data now notifies routers in the
6167 network about entities leaving the network.
6169 At the same time implemented functions silc_server_remove_id
6170 and silc_server_send_remove_id to receive and send REMOVE_ID
6171 packets. The packet is used to notify routers in the network
6172 about leaving entities. The ID removed will become invalid in
6175 * Added function silc_idlist_del_server into server. Removes and
6176 free's server entry from ID list.
6178 * silc_server_private_message function now checks, if we are router,
6179 that the destination ID really is valid ID, naturally.
6181 * In router when NEW_ID packet is received (for new client) the
6182 hash of the Client ID is saved in the ID Cache but the
6183 client->nickname is set to NULL, instead of putting the hash
6186 IDENTIFY command now also checks that client->nickname must be
6187 valid. If it is not if will request the data from the server who
6188 owns the client. Added new function
6189 silc_server_command_identify_check.
6191 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6192 to set the command to already allocated Command Payload.
6194 * Tested private message sending in router environment with two
6195 routers, two servers and two clients. Fixed minor bugs and now
6198 * Fixed segfault from client's NAMES command. Used to crash if
6201 * Forwarded packets must not be routed even if it is not destined
6202 to the receiver. Changed server code comply with this.
6204 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6206 * Added `require_reverse_mapping' boolean value to ServerParams
6207 structure. If TRUE (not default) the server will require that
6208 the connecting host has fully qualified domain name.
6210 If the reverse mapping is not required and hostname could not be
6211 found the IP address is used as hostname.
6213 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6215 * Implemented version string checking to both client and server.
6216 The check is incomplete currently due to the abnormal version
6217 strings used in development version of SILC.
6219 * Changed all command functions in server to use the new
6222 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6224 * Changed char *data to unsigned char *data in ID Cache system to
6225 support binary data as ID Cache data. Changed code to support
6226 binary data in lib/silccore/idcache.c.
6228 * Renamed silc_server_packet_relay_command_reply to
6229 silc_server_command_reply as it is normal packet receiving
6230 function. Rewrote the function to accept command replys for
6231 servers and not only for clients.
6233 * Mark remote router always as registered server if we are connecting
6234 to it. Otherwise, commands sent by the router to us are ignored.
6236 * All ID List find routines now returns the ID Cache Entry pointer
6237 as well if requested.
6239 * WHOIS command works now in router environment, tested with two
6240 routers, two servers and two clients.
6242 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6243 in router environment (as it is almost equivalent to WHOIS) but
6244 hasn't been tested thoroughly. Added new functions:
6246 silc_server_command_identify_parse
6247 silc_server_command_identify_send_reply
6248 silc_server_command_identify_from_client
6249 silc_server_command_identify_from_server
6251 * Disabled route cache adding because adding two different ID's with
6252 same IP replaces the old cache entry thus giving wrong route.
6253 The entry->router->connection is always the fastest route anyway
6254 so route cache may not be needed. Of course, new routes maybe
6255 established after receiving the ID when the entry->router->connection
6256 might not be anymore the most optimal.
6258 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Add route cache for received ID for fast routing.
6262 * Added silc_server_packet_route to route received packet on router
6263 that is not destined to us.
6265 * Renamed silc_server_get_route to silc_server_route_get.
6267 * Added id_string and id_string_len fields into SilcServer to
6268 include encoded ServerID for fast comparing without excess
6269 encoding of the ID's.
6271 * Cleaned up WHOIS command on server side. Added following static
6274 silc_server_command_whois_parse
6275 silc_server_command_whois_check
6276 silc_server_command_whois_send_reply
6277 silc_server_command_whois_from_client
6278 silc_server_command_whois_from_server
6280 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6281 arguments in command replies. All command functions should be
6282 updated to use this macro.
6284 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6286 * Minor typo fixes on command reply handling on server.
6288 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * Added silc_server_command_add_to_channel internal routine to add
6291 the client to the channel after router has created the channel and
6292 sent command reply to the server.
6294 * Added generic silc_server_send_command to send any command from
6297 * Use static buffer with ID rendering instead of duplicating data.
6299 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6301 * Fixed a channel user mode bug when joining to a channel server gave
6302 everybody channel founder rights, oops.
6304 * We mark ourselves as the router of the incoming server connection
6305 if we are router ourselves. This way we can check in some packet
6306 sending functions whether it is locally connected server. For
6307 incoming router connections we put NULL.
6309 * For router sending packets locally means now always sending the
6310 packet cell wide; to local clients and local servers. For normal
6311 server sending packet locally means sending it to only local
6314 * Fixed the JOIN command to really work in router environment. If the
6315 channel is created it is always created by the router. Router is
6316 also responsible of making the initial joining to the channel,
6317 sending JOIN notify to the sending server and distributing
6318 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6319 does not exist server doesn't do anything else but forward the
6320 command to the router which performs everything.
6322 * Added silc_server_send_channel_key function to send the Channel Key
6325 * Added silc_server_create_channel_key to create new channel key. The
6326 channel key is now re-generated everytime someone joins or leaves
6327 a channel, as protocol dictates. Note: channel->key_len is the
6330 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6332 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6333 packet_receive.[ch] to separate packet sending and receiving
6334 routines. The server.[ch] now includes everything else including
6335 actual packet processing (writing and reading data) and other
6338 Renamed silc_server_private_message_send_internal to
6339 silc_server_send_private_message. The routine is still though
6340 used only to relay private messages as server does not send
6341 private messages itself.
6343 Renamed silc_server_new_channel to silc_server_create_new_channel
6344 and added new function sicl_server_new_channel that handles the
6345 incoming New Channel packet. Added also new sending function
6346 silc_server_send_new_channel to send New Channel Payload.
6348 * Added new function silc_server_notify to process incoming notify
6349 packet to the server/router. Server may then relay the notify
6350 to clients if needed.
6352 * Added new function silc_server_new_channel_user to process incoming
6353 New Channel User packet. Router will redistribute the packet and
6354 send JOIN notify to its local clients and locally connected servers
6355 if needed. Normal server will send JOIN notify to its local client
6356 on same channel when received this packet. Added also corresponding
6357 sending function silc_server_send_new_channel_user to sent the
6360 * Added boolean route argument to send_notif_to_channel and
6361 packet_send_to_channel functions to attempt to route the packet
6362 if it is TRUE and send only locally if it is FALSE.
6364 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6366 * silc_server_replace_id now broadcasts the received replace ID
6367 packet if it is not broadcast packet already. The router must
6368 broadcast to inform other routers about changed ID.
6370 * Added backpointer to server's router into SilcServer context in
6371 silcd/server_internal.h.
6373 * Fixed silc_server_packet_broadcast to send correct broadcast
6376 * The channel key is now distributed to the local client as soon
6377 as it is received from the router (in router environment) so that
6378 no other packet may be sent for the channel until client has
6381 * silc_server_remove_channel_user now broadcasts the received
6382 Remove Channel User packet if it is not broadcast packet already.
6383 The router must broadcast to inform other routers about removed
6386 * Added users field into SilcPacketContext that is a reference count
6387 of the context. One can increase the reference count by calling
6388 silc_packet_context_dup which is now changed to just increase the
6389 reference count instead of duplicating the data. The reference
6390 count is decresed by calling silc_packet_context_free that will
6391 free the data after the reference count hits zero.
6393 For now on the packet context and everything allocated into it
6394 (including the raw packet from network) must be freed by calling
6395 the new silc_packet_context_free function. Added also new function
6396 silc_packet_context_alloc that must be used now to allocate the
6397 context. This also means that if a routine is asynchronous from
6398 silc_[client/server]_packet_parse_type the packet context must
6399 be duplicated by calling silc_packet_context_dup. Otherwise it
6400 gets free'd after silc_[client/server]_packet_parse_type returns.
6401 Also, one must remember that if packet is duplicated then its
6402 reference count must be decresed by calling the free function as
6403 many times as it was duplicated.
6405 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6406 from both client and server.
6408 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6410 * Made joining to a channel working in router environment.
6412 * Cleaned up JOIN command on server side and create function
6413 silc_server_command_join_channel internal routine to make the
6416 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6418 * Changed silc_command_pending list to SilcDList. Also, added
6419 `ident' field to SilcServerCommandPending structure to identify
6420 the reply and to call correct callback.
6422 Added silc_server_command_pending_check function to replace the
6423 corresnponding macro. The silc_command_pending list is not
6426 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6427 to set identifier to previously allocated Command Payload. It
6428 is used to set identifier for command when resending Command
6431 * Added silc_command_payload_encode_payload to encode Command
6432 Payload buffer from SilcCommandPayload structure.
6434 * Added silc_argument_payload_encode_payload to encode Argument
6435 payload buffer from SilcArgumentPayload structure.
6437 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6439 * Changed WHOIS command to support router connection on server side.
6440 The whois request is always sent to router unless the server is
6441 standalone server. After server has received the reply from the
6442 router will it send the reply to the client.
6444 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6445 broadcast received broadcast packet. The function is used only
6446 by router. The broadcast packet is always sent to the router's
6449 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6450 render given ID to printable string, for log files for example.
6452 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6454 * Made basic router to router connections working. At least they
6455 can now connect to each other but nothing really works the way
6456 they are supposed - yet.
6458 * Added new initiator token to RouterConnection configuration
6459 file in silcd/serverconfig.[ch]. It is used to tell whether we
6460 are the initiator to the remote router or whether we'll expect
6461 the other end to connect.
6463 * Moved registering of listener task to silc_server_init, hence
6464 the server starts listenning as soon as it is run, even if it
6465 does not have connections to other routers. Let's see how well
6468 * Changed default connection retry timeouts for more suitable in
6471 * Removed cipher and such arguments from silc_idlist_add_client
6472 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6473 Added new function silc_idlist_add_data to add the keys and stuff
6476 * Added SilcIDListData structure and added it to SilcClientEntry
6477 and SilcServerEntry as their first field in the structure. This
6478 way we can explicitly cast the ID entries to the SilcIDListData
6479 structure and get common data for the entries. In past, we had
6480 to first check what type of connection it is and then cast it to
6481 correct ID entry type. Now, we can directly cast the opaque
6482 pointer to the SilcIDListData (no matter what ID entry it actually
6483 is) and get the data needed.
6485 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6487 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6488 in some circumstances even if threre were timeout tasks, though not
6489 IO tasks, but tasks anyway. Now fixed.
6491 * Defined SilcServerConnection structure to hold connection specific
6492 stuff about directly connected servers and routers. The definition
6493 is currently in silcd/server_internal.h. I thought about having
6494 a bit more important role fro this struct but for now it is used
6495 only when connecting to other server (or router actually).
6497 * Added connecting retry support in server when connecting to
6498 router(s). The retry feature implement exponential backoff
6499 algorithm. Also, added SilcServerParams structure to hold default
6500 parameters for server. For now, it include these retry settings
6501 and are hard coded. After server is moded to be as Silc Server
6502 Library this structure will be more important.
6504 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6506 * Changed client librarys channel->clients table to SilcList and
6507 changed code accordingly.
6509 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6511 * Changed client's channel table to SilcList and changed code
6512 accordingly. Also changed SilcChannelClientEntry to include back-
6513 pointer to the channel so that client entry can use that structure
6514 as list as well and we have fast cross-reference to the channel.
6515 This change dramatically decreased the complexity of channel
6516 handling with client entry and vice versa (removed one extra
6517 loop when searching for channel entry from many functions).
6519 * Changed server->sim from table to SilcDList and changed code
6522 * NAMES command can now be used from user interface. It will show
6523 the user list on the channel, neatly.
6525 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6526 Code now saves realname of the user if it becomes available.
6528 * Renamed configure.in to configure.in.pre and made ./prepare
6529 script to automatically add correct version string to
6530 configure.in which it creates from configure.in.pre.
6532 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6534 * NAMES command reply now shows users mode with the nickname when
6537 * Moved silc_client_ch[u]mode[_char] functions from
6538 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6539 place sucks, they are utility functions and should be in some
6542 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6544 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6547 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6551 * Added TRQ (efficient deque and list library) into lib/trq. This is
6552 a very good list library that is currently used in the SILC. Defined
6553 SilcList API over the library because I didn't like the API very
6554 much. See lib/trq/silclist.h for the API and examples of how to
6555 use the API. Fixed various places in the code to use the new
6556 SilcList API. The SilcList is meant for lists that has a structure
6557 already defined as a list. It is not suitable to add just some
6558 context to the list (in TRQ, the context is the list actually).
6560 So, I defined SilcDList that can be used for the purpose where
6561 predefined list structure does not exit. This can be used as
6562 such list. Now some context just can be added to the SilcDList.
6563 Currently this list is not used in the SILC just yet, though there
6564 are a lot places where this can replace dynamically allocated
6565 tables and I will fix these places, later, to use SilcDList.
6566 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6567 and use TRQ internally).
6569 Also fixed some annoying warning messages that the original TRQ
6570 code generated. Also minor changes to TRQ's Makefile.in.
6572 * Added support for querying by Client ID to both WHOIS and
6573 IDENTIFY commands into server, as required by the protocol.
6575 * Removed method function pointers from SilcBuffer structure. They
6576 weren't used to anything and just increased the context size for
6577 no good reason. This change also made silc_buffer_alloc and
6578 silc_buffer_free functions inline functions.
6580 * Disabled command flooding detection support until it's fixed so
6581 that it accepts commands in but does not execute them more than once
6584 * Added silc_net_localhost(), to return local hostname, into
6585 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6586 that must be initialized before calling silc_client_init.
6588 * Added new function: silc_server_send_notify_on_channels to send
6589 notify messages to all channels client has joined. It is assured
6590 that the message is sent only once per client.
6592 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6593 lib/silcutil/silcutil.[ch] as silc_format function. The new
6594 function is generic and is used by server as well, not only by
6595 the logging routines.
6597 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6598 the provided version string was not acceptable. Added new function:
6599 silc_ske_check_version into lib/silcske/silcske.h. The function
6600 must be implemented by the application (client or server) and it
6601 does not reside in the SKE library. The function checks the version
6602 string remote end sent.
6604 * Added back pointers (to opaque context and to SilcSocketConnection)
6605 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6607 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6608 duplicate packet context structure.
6610 * Changed `notify' client operation to send same arguments as client
6611 receives from server except for ID's. ID's are mapped to correct
6612 ID entry and that is returned. Also, if channel entry is not sent
6613 by server but the notify is for channel the channel entry is sent
6614 to application (otherwise application doesn't know that it is for
6615 channel (library gets it from packet's Destination ID)).
6617 * Added silc_client_remove_from_channels into client library to
6618 remove a client from all channels it has joined to. Used when
6619 received SIGNOFF notify from server. Added also new function
6620 silc_client_replace_from_channels to replace old ID entry with
6621 new ID entry on all channels. Used when received NICK_CHANGE
6624 * Fixed ID Cache list handling in silc_idlist_get_client in
6625 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6626 to get (or query) client by ID.
6628 * Updated TODO list.
6630 * Added connection authentication status message defined by the
6631 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6632 support for these into the code in client and server side.
6634 * Added generic function silc_client_send_command to send any command
6635 with variable argument list. Application should use this function
6636 to send commands if the command functions provided by the library
6637 does not suite for the application's user interface needs.
6639 * Added new `failure' client operation. Application is notified about
6640 received failure packet if client is executing a protocol. In this
6641 case the protocol's execution has failed.
6643 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6644 is required by the protocol.
6646 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6647 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6650 * Added status flag to SilcSKE object to indicate realtime status
6651 of the SKE protocol.
6653 * Application receives now exactly same command reply arguments as
6654 the library receives from server. However, if ID is received the
6655 corresponding ID entry is returned to the application (eg. Client
6656 ID is mapped to correct SilcClientEntry entry and that is returned).
6657 Changed command_reply client operation due to this change.
6659 * Changed all ID's in commands and in command replys as ID Payloads.
6660 Change affected both client and server side codes.
6662 All ID's sent in SILC network (with execption of ID's in SILC
6663 Packet header) are sent in ID Payload to support variable length
6666 * Server now notifies nick changes and notifies all clients on
6667 the channels about the new nickname (about the new Client ID,
6670 * Implemented CMODE command to change channel modes. Supports all
6671 channel modes defined by the protocol specs except ban and invite
6672 lists. (Also, private channel key mode is supported but support for
6673 setting private channel key in client is missing, thus, this mode
6674 has no effect on client side (except that server requires that the
6675 client uses private channel key and normal channel traffic does not
6678 Also, invite mode works per se, but INVITE command does not work
6679 yet correctly, so you can set channel as invite only channel but
6680 inviting clients to the channel does not work (it is yet to be
6681 thought what's the best way to do it).
6683 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6684 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6685 Implemented CUMODE command to change user's mode on the channel.
6686 Supports all modes defined by the protocol specs.
6688 * Added NAMES command reply to return users modes on the channel.
6690 * Removed unnecessary and slow ciphers from lib/silccrypt.
6692 * Set SO_KEEPALIVE option to connection sockets by default.
6694 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6696 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6697 redefined the Notify Payload into protocol specs.
6699 * Added silc_id_payload_parse_id to get ID directly from raw
6702 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6704 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6705 accept searching by Client ID as well.
6707 * Added support for LEAVE and SIGNOFF notify types in client library.
6709 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6710 to parse ID Payload from raw data.
6712 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6714 * Added flags parameter into silc_ske_assemble_security_properties
6715 function in lib/silcske/silcske.[ch].
6717 * Changed notify client operation to fit better for notify messages
6718 sent by server. The notify payload received from server is now
6719 passed to the application (after parsing it to SilcNotifyPayload).
6720 It is application's responsibility to retrieve the arguments
6721 from the payload and show the message the way it wants. The message
6722 sent by server is implementation specific.
6724 * Changed public keys to comply with the protocol specification.
6725 Old public keys are not supported anymore and are not compatible.
6727 * Removed nickname from Channel Payload as the latest draft removed
6728 it. The client must resolve the nickname from the NAMES command
6729 reply received when it joined the channel.
6731 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6733 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6735 * Fixed some errors in protocol specification drafts.
6737 * Created lib/silccore/silcnotify.c to implement Notify Payload
6738 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6739 generic payloads described by protocol specifications. The file
6740 includes implementations for ID Payload and Argument Payload.
6742 * Changed Command Payload implementation to use the new Argument
6743 Payload. Changed command_xxxx_payload to command_payload_xxxx
6744 to comply with SILC coding conventions.
6746 * Added suppport for Argument Payload handling in Notify Payload
6747 implementation as protocol requires it. Added the new support
6748 into server and client lib as well.
6750 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6752 * Added support for multiple nicknames on same channel. [n] is
6753 added locally to the nickname if there are more than one same
6754 nicknames on the channel.
6756 * Server now sends all nicknames that matched WHOIS request.
6757 Client also shows the list received from server.
6759 * Added TOPIC command to client side. User can now set and show
6760 current topic on channel.
6762 * Added MOTD command to client and server. Also, server sends the
6763 motd when client connects to the server.
6765 * Changed version strings to comply ISO 8601.
6767 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6769 * Fixed protocol error handling in client library. It should now
6770 cope even if the SKE fails for some reason.
6772 * Made new protocol specification drafts for submitting to IETF.
6774 * Implemented TOPIC command to server in silcd/command.c.
6776 * Added two new notify types into lib/silccore/silcnotify.h:
6777 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6778 notify nickname change and topic setting/change on a channel.
6780 * API change of command_reply operation in client library. The
6781 application gets now the status type received from server as well.
6783 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6785 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6787 * Cras fixed and optimized the packet handling even further and
6788 it should work now. Minor change to the prototype of function
6789 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6791 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6793 * Added new function into lib/silcutil/silcschedule.[ch]:
6794 silc_schedule_with_fd to select() a specified fd. The function
6795 returns after timeout expires or data arrives or goes. The
6796 function is used by packet routines to wait that all data is
6797 received from network.
6799 * Fixed data reading from network in lib/silccore/silcpacket.c.
6800 The code now assures that all data is read from the fd and then
6801 continues packet processing. This was a bug fix since the code
6802 used to drop some data in some circumstances.
6804 * Added new function into lib/silcclient/client.[ch]:
6805 silc_client_start_key_exchange to start key exchange after
6806 connection has been established to server. The code internally
6807 now uses this funtion but its main purpose was to provide it
6808 for applications that perform their own connecting. After
6809 application has created a connection it merely calls this
6810 function to start the key exchange between client and server.
6811 The library takes care of everything else after that.
6813 Updated also lib/silcclient/README to explain the usage of
6816 * Do not send to application information that connection has
6817 been established. Application gets notified it by connect
6820 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6822 * Applied cras's patch to add silc_schedule_one function. The
6823 function runs scheduler once and returns.
6825 * Fixed the scheduler after cras messed it up. The timeout
6826 handling works now as it's supposed to work.
6828 * Added into lib/silccore/ silcnotify.h to include notify
6829 message types support. Changed silc_server_send_notify*
6830 functions, in server.[ch], to support those new notify types.
6831 Added the support for the notify types into client library,
6832 as well. Added new notify client operation into ops.h in
6835 * Changed silc_server_packet_send_to_channel to send normal
6836 packets instead of just channel message packets. The function
6837 is now used to send the notify packets to channels. It is not
6838 used to send channel message packets anymore, as server never
6841 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6842 va_arg()s as it seems to require it nowadays. I guess, if SILC
6843 is compiled with older va_arg() the new code should work anyway.
6845 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6847 * Splitted core library. Core library (lib/silccore) includes
6848 now only SILC protocol specific core (and common) components.
6849 Created new utility library (lib/silcutil) that includes more
6850 generic purpose stuff. The stuff for util library was taken
6851 from the old core library. This was minor and easy split.
6853 * Created SILC Client Library (lib/silcclient) that includes
6854 implementation of the SILC client without user interface. This
6855 was major move from silc/ directory. The code has been changed
6856 so that it is transparent towards the user interface. The
6857 silc/ directory includes now the same user interface as before
6858 and it uses the new client library. Read lib/silcclient/README.
6859 Basicly, the client library performs everything else related
6860 to SILC except user interface handling. Also, configuration
6861 files are considered to be part of user interface and library
6862 does not handle them.
6864 This change also changed a lot of structures, function naming etc.
6865 Most important change was that SilcClientWindow object was
6866 renamed to SilcClientConnection in the client library. Created
6867 also new file lib/silcclient/ops.h. Also added new files
6868 silc/local_command.[ch] and silc/client_ops.[ch].
6870 All these changes were made to make it easier for user interface
6871 designers to create what ever user interface for the SILC client
6874 It is also expected that the server will be moved to lib
6875 directory as well and SILC Server Library will be created;
6876 sometimes in the future.
6878 * Removed Local commands from lib/silccore/silccommand.h as
6879 they are application specific and new client library does not
6880 handle any of those anymore.
6882 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6883 old client implementation in silc/.
6885 * Added support for callback functions in SILC_LOG_* macros.
6886 Application can now set its own callbacks that will be called
6887 instead of using the default functions that will always print
6888 the debug messages to stderr (or stdout). Also, debugging can
6889 now be disabled by setting silc_debug to FALSE and re-enabled by
6890 setting it to TRUE. Note, that logging will still work even
6891 if debugging is disabled.
6893 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6894 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6895 silc_log_reset_debug_callbacks.
6897 * To enable debugging in silc client one must give now -d
6898 option on command line.
6900 * Changed silc_schedule_init to automatically allocate task queues
6901 if they are not allocated before calling it.
6903 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6905 * Added GMP 3.1 into math library.
6907 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6909 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6910 a channel in SILC network. The packet is used by servers and
6911 routers to notify other routers that user has left a channel.
6912 This little feature was missing until now. Added the feature
6913 to protocol specification as well.
6915 Added functions: silc_server_send_remove_channel_user and
6916 silc_server_remove_channel_user into server.[ch].
6918 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6919 lib/silccore/silcpacket.h. However, they are not implemented
6922 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6924 * Fixed joining to a channel and sending channel messages
6925 between server and router. The channel message sending should
6926 now work inside a cell.
6928 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6930 * Fixed the private message sending between server and router.
6931 The private message sending should now work inside a cell.
6933 * Added silc_server_replace_id into server.[ch] to replace
6934 existing ID in the SILC network.
6936 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6937 and silc_idlist_replace_server_id into idlist.[ch] in server.
6939 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6941 * Fixed the server to server connections. Server can again now
6942 connect to router. Router to router connections probably does
6945 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6947 * Added dynamic protocol registering support. Now protocols can
6948 registered and unregistered on the fly. Patch by cras.
6950 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6952 * Added lib/contrib directory to hold routines that some platforms
6953 don't have but are needed by SILC.
6955 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6956 into lin/contrib to provide getopt() and getopt_long() for
6957 those who don't have it.
6959 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6961 * Added AWAY command to client. When away message is set and
6962 client receives a private message packet the client automatically
6963 replies to the sender with the away message.
6965 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6966 bug seemed to be the cause of recent problems when compiling
6969 * Added version detection support to SKE protocol specification
6970 and added the new changes to the SKE implementation as well.
6971 There were other minor changes in the SKE protocol as well.
6973 Many changes in lib/silcske/silcske.[ch] and in
6974 lib/silcske/payload.[ch].
6976 * Added ^U functionality, clear input line. Patch from cras.
6978 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6980 * Mainly small bugfixes on core library. Fixed some debugging
6981 logging and buffer overflow in silclog.c.
6983 * Updated config.sub and config.guess on the distribution tree.
6985 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6987 * Added command lagging support in server. Client may execute
6988 commands now only once in two seconds.
6990 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6992 * Optimized packet reception. MAC computation and checking is now
6993 also more optimized. A lot previously duplicated code is now
6994 used as generic by both client and server.
6996 * Fixed key pair generation in clientutil.c
6998 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7000 * Added into lib/silccore/silcbufutil.[ch] new function;
7001 silc_buffer_realloc.
7003 * Moved generic packet sending/encryption functions to
7004 lib/silccore/silcpacket.[ch] from client and server. Some
7005 rewriting of the functions.
7007 * Moved all generic packet reception/decryption functions to
7008 lib/silccore/silcpacket.[ch] from client and server. The
7009 packet processing is now much cleaner in both client and server.
7010 These were major changes in both client and server.
7012 * Created many common functions in server to do packet sending.
7013 Previously code were duplicated a lot, this has been removed
7016 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7018 * Rewrote major parts of the ID cache system. Don't know
7019 whether it is better now or not but at least the API is more
7022 * Major rewrite on ID cache stuff on client because of the ID
7023 cache API changes. Added idlist.c to client.
7025 * Also major rewrite on ID cache stuff on server as well.
7026 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7027 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7028 in hand, instead they are all put into the ID cache system now.
7029 All server_idlist_* routines uses ID cache now instead of
7030 traversing its own lists (those lists does not exist anymore).
7031 SilcIDList though still exists. Also, SilcXXXEntry's are
7034 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7036 * Finally made the SKE implementation compliant to the protocol
7037 specification. All mp integers are now binary encoded as
7038 opposed being HEX encoded.
7040 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7043 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7044 functions: silc_[encode/decode]_pem. Also added function
7045 silc_encode_pem_file to PEM encode with newlines ('\n') for
7048 * SILC public keys are now encoded either PEM or binary. Same
7049 option is for private keys as well. By default private keys
7050 are binary encoded and public keys PEM encoded. Silly HEX
7051 encoding were removed.
7053 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7054 function to create fingerprints.
7056 * Fixed a bug in SHA1; does not change the original data anymore.
7058 * Partly implemented INFO command on client and server side.
7059 Fixed CLEAR command. Changes to SERVER command; show current
7060 server(s) when giving command without arguments. Added
7061 VERSION command to client.
7063 * Added check to server that unregistered connections cannot
7064 execute commands (unless it is specificly allowed).
7066 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7068 * Fixed screen refresh.
7070 * Fixed channel joining bug from client. On some circumstances
7071 client tried to join to a channel it had already joined.
7073 * Added public key verification process into client's protocol.c.
7074 The client now verifies the public key from user and saves
7075 it into ~./silc/serverkeys/ directory.
7077 Added into: clientutil.[ch]: silc_client_verify_server_key.
7079 * Changed SKE protocol's silc_ske_initiator_finish function
7080 to accept callback function that verifies the received public
7081 key. Removed old silc_ske_verify_public_key function.
7083 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7085 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7086 silc_pkcs_private_key[_data]_set.
7088 * Made the password and public authentication more cleaner in
7089 server's protocol.c.
7091 * Removed historic and obsolete protocol `channel_auth' from
7092 both client and server.
7094 * Removed wrong way of sending command status messages from
7095 server to client in server's command.c. The old way violated
7096 protocol specification.
7098 Changes to silccore/silccommand.[ch]: removed
7099 silc_command_encode_status_payload -> not needed anymore,
7100 changed silc_command_encode_payload_va to accept extra
7101 argument on variable argument list. The argument type must
7102 now be provided to the function. Also, added new function:
7103 silc_command_encode_reply_payload_va which is same as
7104 normal command_encode_payload_va except command status type
7105 is provided as extra argument.
7107 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7109 * Added ~./silc directory handling. The directory includes the
7110 public and private keys for the client.
7112 Added silc_client_check_silc_dir, silc_client_create_identifier
7113 and silc_client_load_keys.
7115 * Implemented SILC protocol compliant public key. Added public
7116 and private key saving to and loading from files.
7118 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7119 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7120 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7121 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7122 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7124 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7125 silc_pkcs_load_[public/private]_key.
7127 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7129 * Added silc_server_get_route (route.[ch]) to get connection
7130 data for the fastest route for given ID.
7132 * Implemented INVITE command on client and server. The command
7133 were re-defined in the SILC Protocol Specification and the
7134 implementation now complies with the specification.
7136 * Implemented PING command on client and server.
7138 * Implemented NAMES command on client and server. The server side
7139 supports currently only normal server not router server yet.
7140 Some changes to NAMES definition in SILC protocol specification.
7142 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7144 * Implemented LEAVE command on client and server.
7146 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7147 again. This change was made to the protocol as well. Server
7148 should not violate the protocol specification anymore.
7150 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7152 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7153 was tested. SOCKS4 was not but should work anyway.
