28 keepalive_secs, reconnect_count, reconnect_interval,
29 reconnect_interval_max, reconnect_keep_trying and
30 require_reverser_lookup. Added ConnectionParam block, and
31 implemented the connection parameters when connecting as
32 initiator and when accepting connections as responder.
34 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
35 whether given configuration value has been given already.
37 Affected files silcd/serverconfig.[c], server.[c].
39 * Splitted the doc/example_silcd.conf.in. Separated the crypto
40 algorithm parts and created new file silcalgs.conf, that
41 is now included from the example_silcd.conf.in.
43 * Optimized the silc_server_connect_to_router_second to take
44 the connection configuration object from the SilcServerConnection
45 object instead of finding it during the connecting phase.
46 Added the configuration object to SilcServerConnection struct.
47 Affected files silcd/server_internal.h, server.c.
49 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

61 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
63 * Unified the serverconfig.[ch]'s helper function interface.
64 Affected file silcd/serverconfig.[ch].
66 * Removed doc/example_silc.conf.in since it is redundant.
67 The make install will now install irssi/silc.conf file.

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

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

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

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

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

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

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

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

982 to run server on foreground. A patch by debolaz.
983 Affected files silcd/server.c, silcd/silcd.c.
985 * Fixed MOTD to return the MOTD file server name. Affected
986 file silcd/command.c.
988 * Added INFO command reply handling to the Irssi SILC Client.
989 Affected file irssi/src/silc/core/client_ops.c.
991 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
993 * Fixed the silc_idcache_list_* routines to really support
994 the dynamic list. Fixes a crash. Affected file is
995 lib/silccore/silcidcache.c.
997 * Fixed the LIST command reply to really call LIST command's
998 pending callbacks. Affected file silcd/command_reply.c.
1000 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1002 * Update conn->local_entry->nickname after giving NICK
1003 command. Affected file lib/silcclient/command.c.
1005 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1007 * Added the [pid] option to the silcd configuration file
1009 Affected files: serverconfig.[ch] and silcd.c
1011 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1013 * Save fingerprint in WHOIS command reply in server.
1014 Affected file silcd/command_reply.c.
1016 * Fixed NICK commands pending callback registration.
1017 Affected file lib/silcclient/command.c.
1019 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1021 * Use ++server->cmd_ident when sending commands in server,
1022 instead of random number. Affected file silcd/command.c.
1024 * Fixed GETKEY command reply to call actually GETKEY pending
1025 command callbacks. Affected file silcd/command_reply.c.
1027 * A bit stricter check for nicknames. Check for same nickname
1028 in NICK command also. Affected file silcd/command.c.
1030 * Do not call INFO command everytime client ID changes, only
1031 during first connecting. Affected file lib/silcclient/client.c.
1033 * Set the new nickname only after successful command reply for
1034 NICK command is returned by server. Affected file
1035 lib/silcclient/command.c.
1037 * Remove nicknames from nicklist during server_signoff notify.
1038 Should fix /NAMES bit more. The affected file is
1039 irssi/src/silc/core/silc-channels.c.
1041 * Added `fingerprint' field to the SilcIDListData in the
1042 silcd/idlist.h to hold the fingerprint of the client's
1045 Send the fingerprint of the client's public key in WHOIS
1048 Affected files silcd/command.c, and silcd/idlist.[ch].
1050 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1051 create fingerprint from given data.
1053 * Show the fingerprint of the client's public key in WHOIS.
1054 Affected files irssi/src/module-formats.[ch] and
1055 irssi/src/silc/core/client_ops.c.
1057 * Format the multiple same nicknames also during JOIN and
1058 NICK_CHANGE notifys. Affected file is
1059 lib/silcclient/client_notify.c.
1061 * Do not print error on screen for invalid private message
1062 payload since it can come if someone is sending private
1063 messages with wrong key. Affected file
1064 lib/silccore/silcprivate.c.
1066 * Fixed multiple concurrent /PING crash. Affected file
1067 lib/silcclient/command.c.
1069 * Changed the wrong ID encoding. All IP addresses must be
1070 in MSB first order in encoded format. They were encoded
1071 wrong and was in LSB format. Affected files are
1072 silcd/serverid.c, lib/silcutil/silcutil.c.
1074 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1076 * Call the `connect' client operation through the scheduler
1077 in case of error. Affected file lib/silcclient/client.c.
1079 * Call the `failure' client operation even if the error
1080 occurred locally during a protocol. Affected file is
1081 lib/silcclient/protocol.c.
1083 * Added support of sending LIST command to router from normal
1084 server. This way normal server can get list of all channels
1085 in the network too. Fixed the channel list sending in the
1086 server too. Affected files are silcd/command.c, and
1087 silcd/command_reply.[ch].
1089 * Added silc_server_update_channels_by_server and
1090 silc_server_remove_channels_by_server. They are used during
1091 disconnection of primary router and in backup router protocol.
1092 Affected file silcd/server_util.[ch], silcd/server.c and
1093 silcd/server_backup.c.
1095 * Fixed channel adding to global list in IDENTIFY command
1096 reply in server. Affected file silcd/command_reply.c.
1098 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1100 * If the incoming packet type is REKEY or REKEY_DONE process
1101 that packet always synchronously. Fixes yet another MAC
1102 failed error on slow (dialup) connections. Affected file
1103 lib/silcclient/client.c and silcd/server.c.
1105 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1107 * Call check_version SKE callback for initiator too. Affected
1108 file lib/silcske/silcske.c.
1110 * Implemented fix for security hole found in the SKE that was
1111 fixed in the specification few days back; the initiator's
1112 public key is now added to the HASH value computation.
1113 Added backwards support for the old way of doing it too, for
1114 old clients and old servers. Affected file is
1115 lib/silcske/silcske.c.
1117 * Enabled mutual authentication by default in SKE. If initiator
1118 is not providing mutual authentication the responder will
1119 force it. This will provide the proof of posession of the
1120 private key for responder. The affected files are
1121 lib/silcclient/protocol.c and silcd/protocol.c.
1123 * Do not cache anymore the server's public key during SKE.
1124 We do mutual authentication so the proof of posession of
1125 private key is done, and if the server is authenticated in
1126 conn auth protocol with public key we must have the public
1127 key already. Affected file silcd/protocol.c.
1129 * Added new global debug variable: silc_debug_hexdump. If
1130 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1131 file lib/silcutil/silclog.[ch].
1133 * Fixed compilation warning due to char * -> const char *.
1134 Affected files lib/silcutil/silcnet.h, and
1135 lib/silccore/silcauth.[ch].
1137 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1139 * Fixed CMODE command when new channel key was created. If
1140 the creation failed the old key was removed. Next time giving
1141 same command would crash the server since the old key was
1142 freed already. Affected file silcd/command.c.
1144 * Fixed the silc_server_announce_get_channels to not crash
1145 on reconnect. Affected file silcd/server.c.
1147 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1149 * Added silc_log_set_debug_string function to set a regex
1150 string to match for debug output. Only the function names,
1151 or filenames matching the given debug string is actually
1152 printed. This way it is possible to filter out those debug
1153 strings that user is not interested in.
1155 Fixed a bug in silc_string_regexify.
1157 Affected files lib/silcutil/silclog.[ch], and
1158 lib/silcutil/unix/silcunixutil.c.
1160 * Changed the -d options in both server and Irssi SILC client
1161 to take the debug string as argument. Affected files
1162 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1164 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1166 * Added silc_hash_babbleprint to create a Bubble Babble
1167 Encoded fingerprint. The encoding is developed by Antti
1168 Huima (draft-huima-babble-01.txt), and it creates human
1169 readable strings out of binary data. Affected file
1170 lib/silccrypt/silchash.[ch].
1172 * Print the babble print now in addition of fingerprint as well
1173 in Irssi SILC client. Affected files are
1174 irssi/src/fe-common/silc/module-formats.[ch],
1175 irssi/src/fe-common/silc/core/client_ops.c.
1177 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1179 * Fixed a security problem found in SKE. The initiator's
1180 public key too is now added to the HASH hash value creation
1181 which is signed by the responder to create the SIGN value.
1182 This will prevent anyone in the middle to lie to the responder
1183 about the initiator's public key. If this is done now, the
1184 man in the middle will get caught. Updated the protocol
1187 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1189 * Better installation directory handling. Configure module
1190 paths and other paths automatically to example_silc* files
1191 in doc/. A patch by toma.
1193 * Fixed compiler warning from MPI library, and from SILC RNG.
1196 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1197 It can be configured with ./configure. A patch by toma.
1199 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1201 * Find correct make to use in prepare-clean. A patch by
1202 toma. Affected file prepare-clean.
1204 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1206 * Added irssi variables use_auto_addr, auto_bind_ip,
1207 auto_bind_port and auto_public_ip.
1209 * Changed the interface for silc_client_send_key_agreement
1210 in lib/silcclient/silcapi.h
1214 irssi/src/silc/core/silc-core.c
1216 lib/silcclient/silcapi.h
1217 irssi/src/silc/core/silc-channels.c
1218 lib/silcclient/client_keyagr.c
1221 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1223 * Added silc_pkcs_public_key_compare to compare two
1224 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1226 * Check that the client who set the founder mode on the
1227 channel is the same client that is giving the founder
1228 mode to itself. It is done by comparing the saved public
1229 key (it is saved even in the authentication is passphrase).
1230 Affected file silcd/command.c.
1232 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1234 * Do not process packet for disconnected socket connection.
1235 Affected file lib/silccore/silcpacket.c.
1237 * Process the DISCONNECT packet through scheduler in the
1238 client library. Affected file lib/silcclient/client.c.
1240 * Fixed the silc_client_packet_parse to not to increase
1241 the packet sequence number if the conn->sock and the
1242 current socket connection is not same. This can happen
1243 for example during key agreement when the conn includes
1244 multiple socket connections (listeners). Affected file
1245 lib/silcclient/client.c.
1247 * The sender of the file transfer request now provides also
1248 the pointer (listener) for the key exchange protocol. If
1249 the listener cannot be created then it sends empty key
1250 agreement and lets the receiver provide the listener.
1252 Added `local_ip' and `local_port' arguments to the
1253 silc_client_file_send. If they are provided they are used,
1254 if not then it will attempt to find local IP address, if
1255 not found or bind fails then the remote client will provide
1258 Affected files are lib/silcclient/client_ftp.c and
1259 lib/silcclient/silcapi.h.
1261 * Extended the FILE SEND command to support defining the
1262 local IP and port for key exchange listener. They are
1263 optional. Affected file irssi/src/silc/core/silc-servers.c.
1265 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1267 * Defined to WHOIS command reply the sending of fingerprint
1268 of the client's public key (if the proof of posession of the
1269 corresponding private key is verified by the server).
1270 Updated to the protocol specification.
1272 * Added support of receiving the client's public key's
1273 fingerprint in command reply in client library. Affected
1274 file is lib/silcclient/command_reply.c, and
1275 lib/silcclient/idlist.[ch].
1277 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1279 * Do not send over 128 chars long nickname to the server
1280 in NICK command. Affected file lib/silcclient/command.c.
1282 * Do not send over 256 chars long channel names to the server
1283 in JOIN command. Affected file lib/silcclient/command.c.
1285 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1287 * Assure that silc_server_close_connection cannot be called
1288 twice for same socket context. Affected file is
1291 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1293 * Send error message to application if opening file for
1294 writing during file transfer fails. Affected file is
1295 lib/silcclient/client_ftp.c.
1297 Remove all file transfer sessions for a client that we're
1298 removing from ID cache.
1300 Affected file is lib/silcclient/client_ftp.c.
1302 * Fixed silc_net_addr2bin to return correct address. Affected
1303 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1305 * Fixed file transfer session removing on signoff notify.
1306 Affected file irssi/src/silc/core/silc-servers.c.
1308 * Added the SilcClientFileError to be returned in the monitor
1309 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1310 Affected file lib/silcclient/silcapi.h.
1312 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1314 * Fixed a crash in silc_client_ftp_free_sessions and
1315 silc_client_ftp_session_free_client. Affected file
1316 lib/silcclient/client_ftp.c.
1318 * Added `disabled' field in the SilcChannelEntry in the server
1319 to indicate if the server entry is disabled. Affected file
1320 silcd/idlist.h, silcd/command[_reply].c.
1322 * SILC server adds now /var/run/silcd.pid everytime it is
1323 started. Affected file silcd/silcd.c.
1325 * Added silc_server_packet_send_clients to send a packet to
1326 the provided table of client entries. Affected file
1327 silcd/packet_send.[ch].
1329 * Fixed a crash in client resolving in client_prvmsg.c in
1330 client library. Affected file lib/silcclient/client_prvmsg.c.
1332 * Do not actually remove the client directly from ID cache
1333 during SERVER_SIGNOFF, but invalidate it. This way we
1334 preserve the WHOWAS info for the client. Affected file
1335 silcd/server_util.c.
1337 * Fixed SERVER_SIGNOFF notify handling in the server. The
1338 server is now able to process incoming SERVER_SIGNOFF notify
1339 for a server that it doesn't even know about. It will remove
1340 the clients provided in the notify. Affected file
1341 silcd/packet_receive.c.
1343 * Check for partial packet in data queue after every packet that
1344 was found from the queue. Return and wait for more data if
1345 there is partial data in queue. Affected file is
1346 lib/silccore/silcpacket.c.
1348 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1350 * Added SilcClietFileError enum to indicate error in
1351 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1352 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1353 Affected files lib/silcclient/silcapi.h and
1354 lib/silcclient/client_ftp.c.
1356 * Check that newsize in silc_buffer_realloc is larger than
1357 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1359 * Added better monitor of file transfers. It now monitors
1360 key agreement protocol during the file transfer too. Added
1361 error reporting too. Affected files
1362 irssi/src/silc/core/silc-servers.c,
1363 irssi/src/fe-common/silc/module-formats.[ch].
1365 * Wrote a help file for FILE command.
1367 * Added silc_rng_global_get_byte_fast to get not-so-secure
1368 random data as fast as possible. Random data is read from
1369 /dev/urandom if available and from the SILC RNG if not
1370 available. It is used in padding generation. Affected file
1371 lib/silccrypt/silcrng.[ch].
1373 * All packets in client library are now processed synchronously.
1374 Optimized packet processing a lot. Affected file
1375 lib/silcclient/client.c.
1377 * All server connection packets are processing synchronously
1378 now in server, to optimize packet processing. Affected file
1381 * Include files are installed now only in Toolkit distribution
1382 if make install is given. Affected files: all Makefile.am's.
1384 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1386 * Assure that silc_client_notify_by_server_resolve does not
1387 resolve the client information multiple times. If it cannot
1388 be found by the first it cannot be found at all. Affected
1389 file lib/silcclient/client_notify.c.
1391 * Fixed WHOWAS command reply calling. Affected file
1392 lib/silcclient/command_reply.c.
1394 * Removed all references to silc_idlist_get_client from the
1395 Irssi SILC client since that call is internal call used by
1396 the library. The Irssi SILC client will use now client
1397 retrieval functions found in silcapi.h.
1399 * Fixed a bug in resolving nickname info before sending
1400 private message. It used freed memory. Affected file
1401 irssi/src/silc/core/silc-servers.c.
1403 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1405 * Assure my_channels statistics cannot go negative in server.
1406 Affected files silcd/server.c, silcd/server_util.c.
1408 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1410 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1412 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1414 * Win32 Toolkit changes. Affected files

1418 lib/sftp/sftp_fs_memory.c.
1420 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1422 * Added silc_net_localip to return local host's IP address.
1423 Affected file lib/silcutil/silcnet.[ch].
1425 * If key exchange or rekey protocol is active for a connection
1426 parse all packets syncronously since there might be packets
1427 in packet queue that we are not able to process without first
1428 processing packets before them. Affected file silcd/server,
1429 lib/silcclient/client.c.
1431 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1432 whether library should continue processing the packet.
1433 Affected file lib/silccore/silcpacket.h.
1435 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1436 SilcSFTPMonitorData to SFTP server to monitor various
1437 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1438 lib/silcsftp/sftp_server.c.
1440 * Added silc_file_size to return file size. Affected file
1441 lib/silcutil/silcutil.[ch].
1443 * Implemented the file transfer support for the client library.
1444 Added preliminary support for simple client to client one-file
1445 transmission. Affected file lib/silcclient/client_ftp.c,
1446 lib/silccilent/client.[ch].
1448 * Added new local command FILE to the Irssi SILC Client.
1449 It is used to perform the file transfer. It has subcommands
1450 SEND, RECEIVE, SHOW and CLOSE. Affected files
1451 irssi/src/silc/core/client_ops.c,
1452 irssi/src/silc/core/silc-server.[ch].
1454 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1456 * Relay the SILC_PACKET_FTP in the server. Affected files
1457 silcd/server.c and silcd/packet_receive.c.
1459 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1461 * Renamed silc_file_read and silc_file_write to functions
1462 silc_file_readfile and silc_file_writefile. Added function
1463 silc_file_open and silc_file_close. Affected files
1464 lib/silcutil/silcutil.[ch].
1466 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1468 * Resolve the client info when received private message or
1469 channel message for a client which nickname we don't know.
1470 Affected files lib/silcclient/client_prvmsg.c and
1471 lib/silcclient/client_channel.c.
1473 * Do not crash in /KEY if client is not connected. Affected
1474 file irssi/src/silc/core/silc-channels.c.
1476 * Added SilcClientStatus field to the SilcClientEntry in the
1477 lib/silcclient/idlist.h.
1479 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1480 is incomplete and is being resolved, it won't be resolved
1483 Make sure also that USERS command reply does not resolve
1484 twice information. Affected file is
1485 lib/silcclient/command_reply.c.
1487 Make sure that silc_client_get_clients_by_list does not
1488 resolve twice same information.
1490 * Check for valid client->id in the silc_server_free_client_data.
1491 Affected file silcd/server.c.
1493 * Fixed /GETKEY nick@server not to crash if the server entry
1494 is not found. Affected file lib/silcclient/command.c.
1496 * Fixed the silc_server_check_cmode_rights to check the
1497 requested modes correctly. Affected file silcd/command.c.
1499 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1501 * Better checks for non-printable chars in nick added.
1502 Affected file silcd/command.c.
1504 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1506 * Call the silc_server_udpate_servers_by_server in the
1507 primary router that comes back online in the backup resuming
1508 protocol. Otherwise it routes packets wrong. Affected file
1509 silcd/server_util.[ch], silcd/server_backup.c.
1511 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1513 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1514 lib/silcutil/silcbuffmt.[ch].
1516 * Redefined the SILC packet header to include the padding
1517 length. Affected file lib/silccore/silcpacket.[ch].
1519 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1520 length for maximum padding up to 128 bytes). Affected
1521 file lib/silccore/silcpacket.h.
1523 * Removed all backwards support for old 0.5.x MAC thingies.
1524 The SILC packet header change makes it impossible to be
1525 backwards compatible.
1527 * Send the ENDING packet with timeout in the backup resuming
1528 protocol. This is to assure that all routers has connected
1529 to the primary router. Affected file silcd/server_backup.c.
1531 * Changed the RNG to take the first IV from random data. It
1532 used to take it from zero actually. Changed the RNG also
1533 to use /dev/urandom during session. /dev/random is used
1534 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1536 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1538 * Changed the SILC packet header to have the first two bytes
1539 (the packet length) encrypted. Affected files aroung the
1540 code tree, lib/silccore/silcpacket.[ch]. Removed the
1541 SilcPacketCheckDecrypt callback. It is not needed anymore
1542 since the silc_packet_receive_process will determine now
1543 whether the packet is normal or special.
1545 * Implemented the unidirectional MAC keys. Affected files
1546 lib/silcske/silcske.c, silcd/protocol.c and
1547 lib/silcclient/protocol.c.
1549 * Implemented the packet sequence number to the MAC computation.
1550 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1551 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1552 lib/silcclient/protocol.c.
1554 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1556 * Allow backup router to announce servers. All servers
1557 announced by backup router are added to the global list
1558 automatically. Update hte server's socket to our primary
1559 router also when backup router announces a server.
1560 Affected file silcd/packet_receive.c.
1562 * Do not update the client->router in the function
1563 silc_server_udpate_clients_by_server if the client is on
1564 global list. We might fail to find any specific server
1565 for locally connected clients and local cell clients. They
1566 should still use the `from' and not `to' as client->router.
1567 This fixes backup router resuming protocol. Affected file
1568 silcd/server_util.c.
1570 * Decrease channel statistics count only if the channel
1571 deletion worked. Affected files are silcd/server.c and
1572 silcd/server_util.c.
1574 * Added silc_server_update_servers_by_server to update origin
1575 of all server entries. Used during backup router protocol.
1576 Affected files silcd/server_util.[ch], silcd/server.c. and
1577 silcd/backup_router.c.
1579 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1580 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1581 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1582 lib/silccrypt/silchmac.c.
1584 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1586 * Assure that router cannot reroute the same channel message
1587 to the sender. Affected file silcd/packet_receive.c.
1589 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1591 * Made better checks that the channel message is not sent
1592 to the router it came from. Affected file is
1593 silcd/packet_send.c. Fixed memory leak too.
1595 * Announce informations for incoming router connection, but
1596 only after checking if it is replaced by backup router.
1597 Affected file silcd/packet_receive.c.
1599 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1601 * Fixed the backup resuming protocol to work in multiple
1602 router environment. Affected file silcd/server_backup.c.
1604 * Route packet only to one router in the function
1605 silc_server_packet_send_to_channel. Affected file is
1606 silcd/packet_send.c.
1608 * Fixed silc_server_send_notify_dest to set the broadcast
1609 flag. Fixed the silc_server_send_notify_topic to actually
1610 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1611 Affected file silcd/packet_send.c.
1613 * Changed the SFTP Filesystem interface. Changed the
1614 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1615 the filesystem operation function. The SilcSFTPFilesystem
1616 is now a context that is allocated by all filesystem allocation
1617 functions and it already includes the operations structure
1618 and filesystem specific context. It is given as argument
1619 now to the silc_sftp_server_start. This made the interface
1620 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1621 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1623 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1625 * Changed the backup router adding and getting interfaces
1626 in the server. The router that will be replaced by the
1627 specified backup router is now sent as argument. Affected
1628 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1631 * Added silc_net_addr2bin_ne to return the binary form of
1632 the IP address in network byte order. Affected files

1635 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1637 * Check for existing server ID in silc_server_new_server
1638 and in silc_server_connect_to_router_final and remove the
1639 old entry if it exists. Affected file silcd/packet_receive.c,
1642 * Send the channel message always to only one router, either
1643 in upstream or downstream. Affected file is
1644 silcd/packet_send.c.
1646 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1648 * Wrote the definition of the backup resuming protocol to the
1649 protocol specification.
1651 * Removed one redundant channel key generation from normal
1652 server during joining procedure. Removed one redundant
1653 channel key sending from server to router during joining
1654 procedure. Affected file silcd/command.c.
1656 * Made minor bugfixes to the backup router resuming protocol.
1657 Affected file silcd/server_backup.c, server.c.
1659 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1661 * Added --disable-asm configuration option. Affected files
1662 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1665 * Implemented the backup resuming protocol that is used to
1666 resume the primary router position in the cell after the
1667 primary router comes back online. Affected files
1668 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1669 and silcd/server_util.[ch].
1671 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1673 * Sleep two (2) seconds after sending QUIT command to server.
1674 Affected file lib/silcclient/command.c.
1676 * Assure that if outgoing data buffer is pending do not force
1677 send any data. Affected file silcd/packet_send.c.
1679 * Assure that if outgoing data buffer is pending do not force
1680 send any data. Affected file lib/silcclient/client.c.
1682 * Implemented the backup router support when the primary router
1683 goes down. The servers and routers can now use the backup
1684 router as new primary router without loosing connectivity.
1686 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1688 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1689 in the server to indicate disabled entry. All data read
1690 from the connection will be ignored and no data is sent
1691 for entry that is disabled. Affected files are
1692 silcd/idlist.h, silcd/server.c.
1694 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1696 * Created SFTP client and server test programs in the
1697 lib/silcsftp/tests directory.
1699 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1701 * Implemented memory filesystem (virtual filesystem) for
1702 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1705 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1707 * Implemented the SFTP (SSH File Transfer Protocol) to the
1708 lib/silcsftp. It includes SFTP client and SFTP server
1711 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1713 * Moved lib/silccore/silcprotocol.[ch] to the
1714 lib/silcutil library.
1716 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1717 take variable argument list pointer as argument. Affected
1718 file lib/silcutil/silcbuffmt.[ch].
1720 * Added silc_buffer_set function that is used to set data
1721 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1722 Affected file lib/silcutil/silcbuffer.h.
1724 * Changed various routines in the core library to use the new
1725 silc_buffer_set instead of allocating new buffer only for
1728 * Added 64-bit value formatting and unformatting support to the
1729 silc_buffer_[un]format routines. Affected file is
1730 lib/silcutil/silcbuffmt.[ch].
1732 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1733 to includes/bitmove.h.
1735 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1737 * Fixed channel user mode saving in client library. Affected
1738 file lib/silcclient/command[_reply].c.
1740 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1742 * Defined the file transfer to the SILC Protocol. Added
1743 new packet type SILC_PACKET_FTP and defined File Transfer
1744 Payload. The mandatory file transfer protocol is SFTP
1745 (SSH File Transfer Protocol). Affected file in addition
1746 of the internet draft is lib/silccore/silcpacket.h.
1748 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1749 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1750 is used as part of backup router protocol when the primary
1751 router of the cell is back online and wishes to resume
1752 the position as primary router.
1754 * Redefined the MAC generation keys in the protocol. The
1755 same key is not used anymore in both direction. Both
1756 direction will now use different keys for sending and
1757 receiving. This fixes a potential security flaw. This
1758 change causes incompatibilities in the protocol.
1760 * Redefined also the MAC computation from the packet.
1761 An packet sequence number is now added to the MAC
1762 computation. This prevents possible replay attacks against
1763 the protocol. This change too causes incompatibilities
1766 Added `sequence' field to the SilcPacketContext to hold
1767 the current sequence number for the packet.
1769 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1771 * Added `created' field to the SilcIDListData in the file
1772 silcd/idlist.h to indicate the time when the entry was
1775 * Added `created' field to the SilcChannelEntry too. Affected
1776 file silcd/idlist.h.
1778 * Added `creation_time' aguments to all the announcement functions
1779 in the server. If it is provided then only the entries that
1780 was created after the provided time frame are actually
1781 announced. Affected file silcd/server.[ch].
1783 * The protocol says that the Channel ID's IP address must be
1784 based on the router's IP address. Added check for this in
1785 the silc_server_new_channel when processing incoming New Channel
1786 Payload. Affected file silcd/packet_receive.c.
1788 * Print out the correct version with --version in SILC client.
1789 Affected file irssi/src/silc/core/silc-core.c.
1791 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1793 * Fixed WHOWAS command to check for completnes of the client
1794 entry always, not just when the command is coming from client.
1795 Affected file silcd/command.c.
1797 * Added new function silc_server_packet_queue_purge to purge the
1798 outgoing data queue to the network. After the function returns
1799 it is guaranteed that the outgoing packet queue is empty.
1800 Affected file silcd/packet_send.[ch].
1802 * Purge the outgoing packet queue in the rekey protocol's final
1803 callback to assure that all rekey packets go to the network
1804 before quitting the protocol. Affected file silcd/server.c.
1806 * Added silc_client_packet_queue_parse as similar function as
1807 in server to the client library. The affected file is
1808 lib/silcclient/client.c.
1810 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1812 * Splitted silcd/server.c and created silcd/server_util.[ch]
1813 for utility functions.
1815 * Added new socket flag SILC_SF_DISABLED to indicate that the
1816 connection is open but nothing can be sent to or received from
1817 the connection. Affected file lib/silcutil/silsockconn.[ch].
1818 The checking for disabled socket is checked in the low level
1819 silc_socket_write and silc_socket_read functions.
1821 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1823 * Allow only nicknames and channel names that fits into the
1824 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1826 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1828 * When processing JOIN command reply in server check that if
1829 the channel exists in our global list we'll move it the local
1830 list. Affected file silcd/command_reply.c.
1832 * Fixed the check whether client is joined on the channel already
1833 in JOIN command. Affected file lib/silcclient/command.c.
1835 * Fixed the JOIN command reply to check whether the channel
1836 already exists. Affected file lib/silcclient/command_reply.c.
1838 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1840 * Added silc_ske_status_string to map the SKE error numbers
1841 to readable strings. The affected files are
1842 lib/silcske/silcske[_status].[ch].
1844 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1846 * Do not show the private channels on the WHOIS channel list
1847 as it is not allowed by the protocol. The affected file is
1850 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1852 * Assure that the packet length digged from the actual packet
1853 is something sensible in the silc_packet_decrypt_rest_special
1854 in lib/silccrypt/silcpacket.c.
1856 * Free and NULL the allocated pointer in silc_hmac_alloc if
1857 the HMAC allocation fails. The affected file is
1858 lib/silccrypt/silchmac.c.
1860 * Print the selected security properties to the log files in
1861 the server. Affected file silcd/protocol.c.
1863 * Add SKE's reference counter even if calling the completion
1864 callback manually. Otherwise it goes negative, although it
1865 does not cause any problems. The affected file is
1866 lib/silcske/silcske.c.
1868 * Remove the client entry with short timeout after giving the
1869 KILL command. Affected file lib/silcclient/command.c.
1871 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1872 case all found clients are already disconnected (WHOWAS would
1873 found them) in the server. Affected file silcd/command.c.
1875 * Update the last_receive (time of last data received) to be
1876 updated only when received private or channel message so that
1877 the idle time showed in WHOIS makes more sense.
1879 * Added boolean field `valid' in to the SilcClientEntry in the
1880 client library to indicate whether the entry is valid or not.
1881 This fixes the nickname change bug on channel when changing
1882 the nickname to be same than the old (like nick to Nick) the
1883 nickname formatter doesn't set the new nick anymore to Nick@host.
1884 Affected file lib/silcclient/idlist.[ch].
1886 * Now actually fixed the nickname changing on disconnection.
1887 Added new function silc_change_nick to the Irssi SILC Client.
1888 Affected file irssi/src/silc/core/client_ops.c,
1889 irssi/src/silc/core/silc-nicklist.[ch].
1891 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * Check that the public key exists in the GETKEY command before
1894 trying to encode it. Affected file silcd/command.c.
1896 * Print some notifications on received public keys with GETKEY
1897 command in the Irssi SILC Client. Affected files are
1898 irssi/src/fe-common/silc/module-formats.[ch],
1899 irssi/src/silc/core/client_ops.c.
1901 * Use IDENTIFY command to resolve the server information in the
1902 GETKEY command instead of INFO command. Affected file
1903 lib/silcclient/command.c.
1905 * All command reply functions in the client library now calls
1906 the pending command reply callbacks even if an error has
1907 occurred. The server has done this a long time and now it was
1908 time to move the client library to this as well. Now all
1909 errors can be delivered back to the pending command reply
1910 callbacks if necessary. Affected files are
1911 lib/silcclient/command[_reply].[ch].
1913 * Change the nickname on disconnection back to the username
1914 because in reconnect the server will enforce it to it anyway.
1915 Affected file irssi/src/silc/core/silc-servers.c.
1917 * Fixed a config file parsing bug in the Irssi SILC client.
1918 Affected file irssi/src/silc/core/clientconfig.c.
1920 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1922 * When printing the channel mode on JOIN, verify that the
1923 channel key and channel's HMAC are valid. Affected file
1924 irssi/src/silc/core/client_ops.c.
1926 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1928 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1929 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1930 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1932 * Removed channel key rekey task deleting from the function
1933 silc_server_save_channel_key. Affected file silcd/server.c.
1934 Added explicit timeout task context instead that is used to
1935 delete the task if we are registering a new task before the
1936 new task has elapsed.
1938 * When channel key rekey occurs the client library now saves
1939 the old channel key for a short period of time (10 seconds) and
1940 is able to use it in case some is still sending channel
1941 messages encrypted with the old key after the rekey. Affected
1942 file lib/silcclient/[idlist.h|client_channel.c].
1944 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1946 * Added check to the silc_server_new_id_real to not accept
1947 new ID if it is the sender's own ID. Affected file is
1948 silcd/packet_receive.c.
1950 * Assure that we do not announce ourself or the one we've
1951 sending our announcements when we're router and are announcing
1952 servers to our primary router. Affected file silcd/server.c.
1954 * Fixed silc_server_command_identify_check_client to assemble
1955 correct WHOIS packet. It send corrupted WHOIS packet and
1956 caused problem with router to router connections. Affected
1957 file silcd/command.c.
1959 Fixed also silc_server_command_whois_check the same way
1960 as for the IDENTIFY command.
1962 * Added new SilcIDListStatus to the server in the SilcIDListData
1963 structure. The status now includes the current status of
1964 the entry (like registered, resolved etc.). Affected file
1965 silcd/idlist.[ch]. Defined a bunch of different status types
1966 as well. This replaced the old boolean registered field as well.
1968 Added resolve_cmd_ident field to the SilcClientEntry structure
1969 too so that if the entry is for example being resolved so
1970 another command may attach to the same pending command reply
1971 without requiring to resolve the same entry again. This concept
1972 should optimize the WHOIS and the IDENTIFY resolving under
1973 heavy load by taking away unnecessary resolving for entries
1974 that are being resolved already.
1976 Added support for adding multiple pending commands for one
1977 command idenfier. Affected file silcd/command[_reply].[ch].
1979 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1980 before deleting the data. Otherwise the hash table will have
1981 freed data in comparison functions. Affected file is
1982 silcd/command_reply.c.
1984 * Fixed silc_idlist_replace_client_id to add the new entry to
1985 the cache with NULL nickname. Otherwise there will be invalid
1986 memory as the nickname after the nickname is freed. Affected
1987 file silcd/packet_receive.c.
1989 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1990 saved into wrong slots because the previous number of entries
1991 was not taken into account. Affected file silcd/idlist.c.
1992 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1994 * If we are router and we receive JOIN notify to a channel that
1995 does not have any users then notified client is marked as the
1996 channel founder, as it is it. The affected file is
1997 silcd/packet_receive.c
1999 * Added to the extended hash table API's table_del_*ext functions
2000 the destructor as argument too, so that the caller can decide
2001 which destructor to use or whether to use destructor at all.
2002 Affected file lib/silcutil/silchashtable.[ch].
2004 * Fixed ID Cache purging. It actually deleted the entries from
2005 the hash table after the data was freed. The hash table ended
2006 up comparing freed memory. The affected file is
2007 lib/silccore/silcidcache.c.
2009 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2011 * Fixed Irssi SILC client's KILL command's HELP syntax.
2013 * The USERS command now resolves the detailed user information
2014 if the userinfo field is missing. Affected file is
2015 lib/silcclient/command_reply.c.
2017 * Do not print error in silc_file_read if the read file does
2018 not exist. Just silently return NULL. Affected file is
2019 lib/silcutil/silcutil.c.
2021 * Fixed the silc_log_output to not wine about NULL filename
2022 and to not create some bogus " " filename. Affected file is
2023 lib/silcutil/silclog.c.
2025 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2027 * Fixed various printing bugs on the user interface in the
2028 Irssi SILC Client. Minor changes that were forgotten from
2031 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2033 * Fixed the configure.in.pre and the compilation and distribution
2034 environment to support the new autoconf 2.52. That version is
2035 now required to compile the CVS trunk.
2037 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2039 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2040 to generally parse user@fqdn format strings. Affected file
2041 lib/silcutil/silcutil.c.
2043 * Added nickname_format and nickname_force_format fields to the
2044 SilcClientParams structure. The first one defines the format
2045 for the nicknames that the library will enforce if the receives
2046 multiple same nicknames. The second one is boolean value and
2047 can be used to force the library to always enforce the format
2048 to the nicknames regardles whether there are multiple nicknames
2049 or not. This configurable formatting was employed to flexibly
2050 support accessing multiple nicknames from the user interface.
2051 The userinterface can now set the nicknames to what ever format
2052 they prefer. Affected file lib/silcclient/silcapi.h.
2054 Added function silc_client_nickname_format to the file
2055 lib/silcclient/idlist.c. It performs the nickname formatting.
2057 Added new field `hostname´ to the SilcClientEntry context.
2058 It holds the hostname of the client. Affected file is
2059 lib/silcclient/idlist.h.
2061 * Irssi SILC Client sets the nicknames in nick@hostn format.
2062 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2063 irssi/src/silc/core/silc-core.c.
2065 The WHOIS printing now also shows both the real nickname and
2066 the formatted nickname so that user knows how to access the
2067 user if there are multiple same nicknames cached. Affected
2068 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2069 printing formatting too to take the hostname now as a separate
2070 argument. The Affected file is
2071 irssi/src/fe-common/silc/modules-formats.[ch].
2073 * Changed the silc_client_get_clients_local to accept the formatted
2074 nickname as argument. It accepts the real nickname too but the
2075 formatted nickname can be used to find the true entry from
2076 multiple entries. Affected file lib/silcclient/silcapi.h and
2077 lib/silcclient/idlist.c.
2079 * Added nickname_format_parse field to the SilcClientParams.
2080 It is a callback function provided by the application to parse
2081 the nickname out of the formatted nickname string. The library
2082 calls it to get the nickname from the formatted string. Since
2083 the application generally knows better the format of the nickname
2084 string it parses it instead of the library, even though library
2085 encodes the formatted string. If the callback function is not
2086 provided then the library will use the string as is. The
2087 affected file is lib/silcclient/silcapi.h.
2089 * All the nickname strings passed to the client library in
2090 commands are now expected to be formatted nickname strings.
2091 If the command does not support the formatted nickname string
2092 it will assume that the sent string is the actual nickname.
2093 Affected file lib/silcclient/command.c.
2095 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2097 * Added public key authentication support to OPER and SILCOPER
2098 commands in the client library. Affected file is
2099 lib/silcclient/command.c.
2101 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2103 * Changed the get_auth_methdod client operation to be asynchronous.
2104 It can be async if the application resolves the authentication
2105 method from the server during the negotiation. Added new
2106 SilcGetAuthMeth completion callback that the application will
2107 call after resolving the authentication method.
2109 Added function silc_client_request_authentication_method that
2110 the application can use to resolve the authentication method
2111 from the server. Added also SilcConnectionAuthRequest callback
2112 that the library will call after the server has replied. The
2113 application can call this function if it does not know the
2114 current authentication method.
2116 Affected files are lib/silcclient/client.c and
2117 lib/silcclient/silcapi.h.
2119 * The Irssi SILC client now automatically resolves the authentication
2120 method incase any configuration information is not present (and
2121 currently there never is). The affected file is
2122 irssi/src/silc/core/client_ops.c.
2124 * Fixed public key authentication from the client library.
2125 Affected file lib/silcclient/protocol.c. Changed also the
2126 protocol specification about the public key authentication in
2127 the connection authentication protocol. The actual data to be
2128 signed is now computed with a hash function before signing.
2130 * Fixed the public key authentication from the server as well.
2131 Affected file silcd/protocol.c.
2133 * Removed the mlock()'s from the memory allocation routines.
2134 Affected file lib/silcutil/silcmemory.c. The ./configure does
2135 not check anymore for the mlock(). Affected file is
2138 * Fixed USERS command in server to allow the execution of the
2139 command for private and secret channels if the client sending
2140 the command is on the channel. Affected file silcd/command.c.
2142 * Fixed silc_client_get_clients_local to return the clients
2143 count correctly. It could return wrong value. Affected file
2144 lib/silcclient/idlist.c.
2146 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2148 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2149 types. The assembler optimizations seemed not to like 64-bit
2150 data types. The assmebler optimizations thus are now enabled
2151 also for BSD systems as opposed to only enable them for Linux.
2153 * Do not check for threads at all on BSD systems. Affected
2154 file configure.in.pre.
2156 * Removed -n and -h options from the Irssi SILC Client since
2157 they are not used in silc.
2159 * Fixed the prime generation to assure that the first digit
2160 of the generated random number is not zero since our conversion
2161 routines does not like number strings that starts with zero
2162 digit. If zero digit is seen the random number is regenerated.
2163 This caused some corrupted RSA keys when the zero first digit
2164 was met. Affected file lib/silcmath/silcprimegen.c.
2166 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2168 * Fixed WIN32 configuration in the ./configure script.
2169 Fixed to include xti.h on environments that has it.
2170 Patches by Carsten Ilchmann and andrew.
2172 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2174 * Changed the silc_id_create_client_id to be collision
2175 resistant. It is now assured that there cannot be created
2176 two same client ID's. I suspect that some weird bugs in
2177 the server were actually caused by duplicate Client IDs.
2178 Affected file silcd/serverid.[ch]. A router receiving
2179 new ID now also assures and informs the sending server
2180 if the ID caused collision.
2182 * Changed the silc_id_create_channel_id to also assure that
2183 there are no collisions.
2185 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2187 * Statement about ignoring the Mutual Authentication flag when
2188 performing rekey with PFS was a bit misleading. It is ignored
2189 if it was set in the initial negotiation, it cannot be even
2190 set in the rekey. Fixed in the ke-auth draft. Started the
2191 new versions of the protocol drafts in the doc/.
2193 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2195 * Fixed a bug in silc_client_command_identify_save when saving
2196 new channel information. The channel name was no duplicated
2197 and caused crash on exit. Affected file is
2198 lib/silcclient/command_reply.c.
2200 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2202 * Fixed the getkey command handling in the server. Send just
2203 empty OK reply to the sender if the key could not be fetched
2204 (but everything else was ok, like the key just was not available).
2205 Changed the public key parameter to optional in the protocol
2206 specs so that empty OK reply can be sent. Affected file
2209 Added a message to Irssi SILC client to tell to user if the
2210 server did not return a public key.
2212 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2214 * Fixed a channel key regeneration bug. It registered new
2215 timeout tasks exponentially until all system resources were
2216 used. Affected file silcd/server.c.
2218 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2220 * Added the SILC Document generator to the scripts/silcdoc.
2221 It can be used to generate the Toolkit Reference Manual out
2222 of the source tree. Internally it will also use the RoboDoc
2223 generator now imported in util/robodoc.
2225 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2227 * Added couple of return's in rekey protocol if error orccurred
2228 during the protocol. The execution must be terminated.
2229 Affected file silcd/protocol.c. Also, terminate the protocol
2230 always with timeout.
2232 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2234 * The client's Client ID was created initally from the wrong
2235 nickname (it could have been in format nick@host) in the
2236 silc_server_new_client. Affected file silcd/packet_receive.c
2238 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2240 * Added some SILC_LOG_ERROR's to various error conditions
2241 if client could not be added to ID cache. Affected files
2242 silcd/packet_receive.c and silcd/server.c.
2244 * When client's sock->user_data is freed, NULL also the
2245 client->router and client->connection pointers. Added check
2246 for these pointers being NULL to various places around the
2247 code. Affected file silcd/server.c.
2249 * Added client->data.registered == TRUE checks to various
2250 places around the code to assure that unregistered client's
2251 are not handled when it is not allowed. Affected file
2254 * Added `bool registered' fields to all
2255 silc_idlist_[server|client]_get_* routines to indicate whether
2256 the fetched client needs to be registered or not. Affected
2257 file silcd/idlist.[ch].
2259 * Add your own entry as registered to the ID cache in the
2260 server. Affected file server.c.
2262 * Fixed a bug in silc_server_new_server. The SilcServer was
2263 set as the new server's context instead of SilcServerEntry.
2264 This naturally caused some weird bugs.
2266 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2268 * Do not delete the channel rekey task when adding it
2269 for in silc_server_create_channel_key.
2271 * Changed the silc_server_create_channel_key to return
2272 TRUE or FALSE to indicate the success of the channel key
2275 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2277 * Fixed MSVC++ project files and added missing files to
2278 Makefiles under win32/.
2280 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2282 * Do not add TCP_NODELAY flag if the operating system
2283 does not have it defined. Affected files are
2284 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2286 * Fixed buffer overflow from Irssi SILC Client. Affected
2287 file irssi/src/fe-common/core/themes.c.
2289 * Fixed double free in client library in the file
2290 lib/silcclient/client.c when disconnecting from server.
2292 * Applied double free patch from cras to Irssi SILC client.
2293 Affected files irssi/src/core/[modules/expandos].c
2295 * Fixed the disconnection handling to Irssi SILC Client.
2296 The application must call silc_client_close_connection
2297 in ops->connect client operation in case of failure of
2298 the connection. Affected file is
2299 irssi/src/silc/core/client_ops.c.
2301 * Do not set sock->protocol to NULL in the function
2302 silc_client_close_connection after executing the protocol's
2303 final callback since the sock might not be valid anymore.
2304 Affected file lib/silcclient/client.c.
2306 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2308 * Do not enable SILC_THREADS if the linking with libpthread
2309 did not happen. Affected file configure.in.pre.
2311 * Added notion to protocol specification that server must
2312 verify the sent authentication payload with CMODE when
2313 setting the channel founder key. Implemented it to the
2314 server. Affected file silcd/command.c.
2316 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2318 * Added _EXTRA_DIST SILC distribution variable to the
2319 distributions file. It is used to conditionally add extra
2320 files or directories to the specific distribution. Affected
2321 files ./prepare, Makefile.am.pre and distributions.
2323 Removed the `_' from the start of the distribution names.
2326 * Added README.WIN32 for instructions to compile the Toolkit
2329 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2331 * Fixed a double free in disconnection in the server. Affected
2332 file is silcd/server.c.
2334 * Fixed the lib/silcske/groups.c to work now also with GMP
2335 MP library. The string conversion did not work when using
2336 specific base and the base is indicated in the string as well.
2338 * Created win32/ directory which now includes MSVC++ specific
2339 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2340 It will appear only in the toolkit distribution
2342 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2344 * Changed the key material distribution function in case when
2345 the hash output is too short. The data is now concatenated
2346 a bit differently than it used to. Made the change to the
2347 SKE protocol specification.
2349 * Added better GMP detection to configure.in.pre. A patch
2352 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2354 * Fixed a minor bug in SKE that might cause some problem on
2355 some platforms. Affected file lib/silcske/silcske.c.
2357 * Added the cookie checking for initiator in the SKE. It checks
2358 that the responder returns the sent cookie unmodified. The
2359 affected file is lib/silcske/silcske.c. Added new SKE
2360 error type INVALID_COOKIE that can be sent during the
2361 negotiation. Fixed some memory leaks as well.
2363 * Added the "invalid cookie" error message to Irssi SILC client's
2366 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2368 * Added `task_max' field to the SilcClientParams to indicate
2369 the maximum tasks the scheduler can handle. If set to zero,
2370 default values are used. Affected file lib/silcclient/silcapi.h.
2372 * Fixed memory leaks in silc_client_close_connection. Affected
2373 file lib/silcclient/client.c.
2375 * Added silc_client_del_client_entry to client library to free
2376 all memory of given client entry. Affected file is
2377 lib/silcclient/idlist.[ch].
2379 * Added new functions silc_client_del_channel and
2380 silc_client_del_server to delete channel and server entries.
2381 Affected file lib/silcclient/[silcapi.h/idlist.c].
2383 * Removed silc_client_del_client_by_id from silcapi.h.
2385 * Fixed the INFO command to return the server's own info
2386 correctly when querying by Server ID. Affected file is
2389 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2391 * Removed the non-blocking settings in WIN32 code in the
2392 silc_sock_[read/write] and added SleepEx instead. Affected
2393 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2394 of input data is now checked with FIONREAD and ioctlsocket.
2396 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2398 * Call silc_schedule_task_del_by_context in the
2399 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2400 Affected file lib/silccore/silcprotocol.c.
2402 * Call silc_protocol_cancel for active protocols in the
2403 silc_server_close_connection if the funtion
2404 silc_server_free_sock_user_data has not been called.
2405 Affected file silcd/server.c.
2407 * Generic tasks cannot be deleted using the del_by_fd
2408 task deleting function since generic tasks does not match
2409 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2411 * Added a notion to SILCOPER help file that the SILCOPER works
2412 only on router server, not on normal server.
2414 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2416 * Added for WIN32 support for the new scheduler as well.
2417 Affected file lib/silcutil/win32/silcwin32schedule.c.
2419 * Fixed the SHA1 implementation to work on various platforms.
2421 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2423 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2424 API. It is part of the scheduler now. Everything else is
2425 as previously but some functions has changed their names.
2426 Checkout the lib/silcutil/silcschedule.h for the interface.
2427 Updated all applications to use the new interface. Affected
2428 files are lib/silcutil/silcschedule.[ch].
2430 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2432 * Found a bug in the SKE implementation. The HASH value,
2433 specified by the protocol, was not computed correctly. The
2434 public key of the responder was not added to the computation
2435 even though it is mandatory. Affected file lib/silcske/silcske.c.
2436 This unfortunately causes incompatibilities with older
2437 clients and servers.
2439 * Added WIN32 specific network init and uninit functions:
2440 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2441 the Winsock2. Affected file lib/silcutil/silcnet.h and
2442 lib/silcutil/win32/silcwin32net.c.
2444 * Set the socket always to nonblocking mode on WIN32 after
2445 reading data or writing data. Affected file is
2446 lib/silcutil/win32/silcwin32sockconn.c.
2448 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2450 * Fixed various compilation problems under WIN32. Affected
2451 files lib/silcutil/win32/silcwin32thread.c and
2452 lib/silcutil/win32/silcwin32schedule.c.
2454 * Removed all _internal.h #includes from public header
2455 files. Internal headers must never be included from
2458 Removed also the lib/silcske/payload_internal.h file.
2460 * All include files that may be needed (public and some others
2461 included by the public headers) by application developers are
2462 now copied to the ./includes directory. It does not copy any
2463 internal headers. Affected file Makefile.defines.pre and all
2464 Makefile.am's under lib/ and subdirs.
2466 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2468 * Do not change the ~/.silc directory's permissions automatically.
2469 Affected file irssi/src/silc/core/clientutil.c.
2471 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2473 * Do not cancel the protocol in silc_server_close_connection
2474 it might cause recursion. Now cancelled in the function
2475 silc_server_free_sock_user_data. Affected file silcd/server.c.
2477 * Fixed the silc_server_remove_clients_by_server to regenerate
2478 the channel keys correctly finally. Added also new function
2479 silc_server_remove_clients_channels to actually do it.
2480 Affected file silcd/server.c.
2482 * Fixed the silc_server_new_channel to not crash by giving
2483 wrong router to the new channel. Affected file is
2484 silcd/packet_receive.c.
2486 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2488 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2489 which is given as argument to the silc_client_alloc now.
2490 It can be used to configure the client and set various parameters
2491 that affect the function of the client.
2493 * The USERS command in server did not check whether the channel
2494 is private or secret. Affected file silcd/command.c.
2496 * Added new argument to the USERS command in protocol specification.
2497 The USERS command now can take the channel name as argument
2498 as well. Added support for this in client and server and
2499 updated the protocol specs.
2501 * Completed the GETKEY command in client. It can be now used
2502 to fetch also servers public key not only some clients.
2503 Affected files lib/silcclient/command[_reply].c.
2505 * Added silc_client_get_server to return server entry by the
2506 server name. Affected files lib/silcclient/silcapi.h and
2509 * Redefined the IDENTIFY command in protocol specification to be
2510 more generic. It now can be used to query information about
2511 any entity in the SILC Network, including clients, servers and
2512 channels. The query may be based either the entity's name
2513 or the ID. Added support for this in both client and server.
2515 Affected files silcd/command.c and lib/silcclient/command.c
2516 and command_reply.c.
2518 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2519 the _from_client and _from_server functions. Affected file
2522 * Added silc_client_get_channel_by_id_resolve to the file
2523 lib/silcclient/silcapi.h to resolve channel information by
2524 its ID. Added also silc_client_get_channel_by_id that
2525 does not resolve it from the server.
2527 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2529 * Added SilcServerEntry context into the client library
2530 to represent one server. The INFO command now allocates
2531 these to save the resolved server info. For now on the
2532 client library will also keep information about servers,
2533 connected and resolved with INFO.
2535 The INFO command now allocates the SilcServerEntry context
2536 and saves the server info there. The COMMAND_REPLY in
2537 the INFO now returns the parameters to application in
2538 same order as defined in the protocol specification.
2540 The entries are cached in the client->server_cache.
2542 * The INFO command is now issued after received the Client ID
2543 from the server. Affected file lib/silcclient/client.c.
2545 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2546 to the application as the mode changer might be server.
2547 It is guaranteed that NULL is not returned anymore to the
2548 application. Affected file lib/silcclient/client_notify.c.
2550 The ID Type is now also passed to the application so that
2551 it can check whether the returned entry is SilcClientEntry
2554 Added new function silc_client_get_server_by_id to return
2555 the server entry by ID. Affected files are the
2556 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2558 * Do not create the channel in the Irssi SILC Client when issuing
2559 the JOIN command but when received the sucessful JOIN command
2560 reply. Otherwise the channel might get created even though we
2561 could not join it. The Affected file is
2562 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2564 * Fixed a channel joining bug in router. The router must also
2565 check the channel modes, invite and ban lists etc. when serving
2566 the JOIN command sent by normal server. Affected file is
2567 silcd/command.c. The router now resolves the client's
2568 information from the server who sent the JOIN command if it
2569 does not know it, and processes the JOIN command only after
2572 * Changed the SilcCommandCb to take new argument; void *context2.
2573 Affected file lib/silccore/silccommand.h
2575 The second argument in the command callbacks in the server now
2576 includes the SilcServerCommandReplyContext if the command was
2577 called as pending command callback from the command reply.
2578 Otherwise it is NULL. When called as pending the status of the
2579 command reply will be checked and if it was erronous the
2580 error will be sent to the original sender of the command.
2581 This way the client always receives the error messages even
2582 though the server was actually the one who received the error
2583 when it resent the command to router, for example. Affected
2584 files silcd/command[_reply].[ch].
2586 * Fixed sending WHOWAS command's error message to client if
2587 the requested client could not be found. It was missing.
2590 * Changed the CMODE and CUMODE commands reply arguments in the
2591 protocol specification. The Channel ID is now sent in both
2592 of the commands to identify the channel. Implemented this
2593 new feature to the client and server. Affected files
2594 lib/silcclient/command_reply.c and silcd/command.c.
2596 * Made better checks for invite and ban lists in the JOIN
2597 command in server. Affected file silcd/command.c.
2599 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * The server now performs the incoming host IP/DNS lookup
2602 using the silc_socket_host_lookup and thus does not block
2603 the server anymore. Affected file silcd/server.c.
2605 * Completed the multi-thread support for SILC Scheduler in
2606 the lib/silcutil/silcschedule.c.
2608 * Fixed the configure.in.pre to detect the pthread correctly
2611 * Fixed a deadlock in silc_task_queue_wakeup in the file
2612 lib/silcutil/silctask.c.
2614 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2616 * Added new function silc_schedule_wakeup that is used in
2617 multi-threaded environment to wakeup the main thread's
2618 schduler. It needs to be used when a thread adds a new task
2619 or removes a task from task queues. After waking up, the
2620 scheduler will detect the task queue changes. If threads
2621 support is not compiled in this function has no effect.
2622 Implemented the wakeup mechanism to both Unix and WIN32
2623 systems. Affected files are lib/silcutil/silcschedule.[ch],
2624 lib/silcutil/unix/silcunixschedule.c and the
2625 lib/silcutil/win32/silcwin32schedule.c.
2627 * Added new function silc_task_queue_wakeup to wakeup the
2628 scheduler by the specified task queue. Affected file
2629 lib/silcutil/silctask.[ch].
2631 * The silc_socket_host_lookup_start now wakes up the scheduler
2632 after adding the timeout task. Affected file is
2633 lib/silcutil/silcsockconn.c.
2635 * The silc_socket_host_lookup is synchronous now if the threads
2636 support is not compiled in. However, the callback is still
2637 called asyncronously through the scheduler, anyway. Affected
2638 file lib/silcutil/silcsockconn.c.
2640 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2642 * Added new function silc_socket_host_lookup to perform
2643 asynchronous IP and FQDN lookups for the socket connection.
2644 Affected files lib/silcutil/silcsockconn.[ch].
2646 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2648 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2649 that may or may not compile the mutex support in.
2651 Changed the silc_mutex_alloc interface. It allocates the
2652 mutex now to the sent pointer and returns TRUE or FALSE.
2654 Affected file lib/silcutil/silcmutex.h.
2656 * Wrote the SILC Task Queue interface to support multi-threads.
2657 Affected file lib/silcutil/silctask.[ch].
2659 * Wrote the SILC Scheduler to support multi-threads. Affected
2660 file lib/silcutil/silcschedule.c.
2662 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2664 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2665 in lib/silcutil/win32/.
2667 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2669 * Defined SILC Mutex API and SILC Thread API and implemented
2670 them for Unix. Affected files are
2671 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2672 lib/silcutil/unix/silcunixmutex.c and
2673 lib/silcutil/unix/silcunixthread.c.
2675 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2677 * Fixed the silc_server_remove_clients_by_server's channel
2678 key re-generation. The hash table handling was incorrect
2679 and would not work with many channels. Affected file is
2682 * Fixed some memory leaks around the server code.
2684 * Rewrote the silc_server_get_users_on_channel to support IPv6
2685 based Client ID's. Affected file silcd/server.c.
2687 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2688 specification. However, a separate document must be written
2689 to define the detailed signing procedure and the payload
2690 associated with the flag. Defined the flag to the
2691 lib/silccore/silcchannel.h as well.
2693 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2695 * Changed the dynamic tables to static size tables in the
2696 lib/silccrypt/silchmac.c.
2698 * Removed GCC dependencies from the code. A patch by cras.
2700 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2702 * Do not show the error "Error receiving packet bla bla"
2703 in server if it really was not an error (-2 means that reading
2704 is pending). Affected file silcd/server.c.
2706 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2708 * Fixed a possible crash in silc_server_remove_clients_by_server
2709 in silcd/server.c. Fixed there also some memory leaks.
2711 * Fixed the silc_idlist_replace_client_id. It could replace
2712 wrong key in the hash table. Affected file silcd/idlist.c.
2714 * Do not check whether there are global users on the channel
2715 if the channel->global_users is FALSE. Affected functions
2716 silc_server_remove_from_one_channel and
2717 silc_server_remove_from_channels in silcd/server.c. Also,
2718 do not check if the removed client is local as we can be
2719 sure that global client was not removed from the channel
2720 and checking for global users is not needed.
2722 * The silc_server_remove_clients_by_server now re-generates
2723 the channel keys correctly for those channels that had
2724 clients removed from them. Affected file silcd/server.c.
2726 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2728 * Found the reason of random crashes in the server. We weren't
2729 ignoring the SIGPIPE signal (which can be sent in write())
2730 and it crashed the server. Affected file silcd/silcd.c.
2732 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2734 * Assure that sock->user_data is not NULL in the function
2735 silc_server_packet_send in silcd/packet_send.c.
2737 * Disconnect the remote connection if it could not be added
2738 to any ID lists in the server. The affected file is
2741 * Check in silc_server_packet_send[_real/dest] that the
2742 socket is not disconnecting and ignore the data if it is.
2743 Affected file silcd/packet_send.c.
2745 * Define inline to __inline on native WIN32 compilation.
2746 Affected file includes/silcwin32.h.
2748 * Added some explicit type casts for inline code since MSVC
2749 require them. Affected files lib/silcutil/silcbuffer.h,
2750 lib/trq/silcdlist.h and lib/trq/silclist.h.
2752 * Print warning in log files from now on if the packet
2753 decryption fails. Affected file silcd/server.c.
2755 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2757 * Changed the `say' client operation's interface to accept
2758 new `type' argument to indicate the type of the message sent
2759 by the library. The application may filter the library's
2760 messages according the type. The affected file is the
2761 lib/silcclient/silcapi.h.
2763 * Added two new functions to lib/silcclient/silcapi.h:
2764 silc_client_del_client and silc_client_del_client_by_id.
2765 Affected file lib/silcclient/idlist.c.
2767 * Moved the clientincludes.h from includes/ to silc/ and
2768 serverincludes.h from includes/ to silcd/.
2770 * The modes for the CMODE and CUMODE are now passed as
2771 uint32 for application with COMMAND_REPLY. The affected
2772 file is lib/silcclient/command_reply.c.
2774 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2776 * /WHOIS without arguments shows client's own information.
2777 Affected file lib/silcclient/command.c.
2779 * Changed PING to not accept any arguments. The specs
2780 says that client can ping only the connected server so
2781 requiring an argument is not needed. Affected file is
2782 lib/silcclient/command.c.
2784 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2786 * Fixed a fatal bug in private message sending and reception
2787 encryption and decryption when using private message keys.
2788 The implementation was incorrect and did not follow the
2789 specification. It causd that some of the message were
2790 lost since it did not use the sending and receiving keys
2791 as the protocol suggests. This has been fixed and will cause
2792 incompatibilities with older clients when sending private
2793 message encrypted with private message keys. Affected files
2794 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2795 and various other in Irssi SILC Client.
2797 Added `responder' boolean argument to the functions
2798 silc_client_add_private_message_key[_ske] to indicate when
2799 the key is added as responder or initiator of the key
2802 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2804 * Removed the silc_ske_check_version function and created
2805 a SilcSKECheckVersion callback. Added also a function
2806 silc_ske_set_callbacks that is now used to set all SKE
2807 callbacks. The callback functions are not given to
2808 the SKE functions anymore, but this function is used to
2811 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2813 * Added `silc_version' argument to the silc_client_alloc
2814 to define the version of the application for the library.
2815 The library will use the version string to compare it
2816 against the remote host's (usually a server) version
2817 string. Affected file lib/silcclient/silcapi.h
2819 * Added the KE protocol context to Key Agreement context
2820 in client library so that we can abort the SKE if it
2821 is in process when we get timeout. Affected file is
2822 lib/silcclient/client_keyagr.c.
2824 * Do not resolve the client ID forever if it returns in the
2825 first time that such client does not exist. This was done
2826 for example with private message. Affected file is
2827 lib/silcclient/client_prvmsg.c.
2829 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2831 * Do not add regex.h for WIN32. The affected file
2832 includes/silcincludes.h.
2834 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2835 not work yet 100%. It generates the DLL's automatically
2836 when compiling with --with-win32 under cygwin.
2838 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2840 * lib/contrib/regex.c is not compiled on WIN32.
2842 * Added silc_net_get_socket_opt function to the
2843 lib/silcutil/silcnet.h.
2845 * Added includes/silcwin32.h for WIN32 specific includes
2848 * Do not use ptime structure or any of the posix process
2849 functions on WIN32 in lib/silccrypt/silrng.c.
2851 * Added silc_gettimeofday to provide generic function
2852 for struct timeval on all platforms. Added the function
2853 to lib/silcutil/silcutil.h.
2855 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2857 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2858 library as they clearly belong there. As a plus side we
2859 can make the actual socket connection routines platform
2862 Added also new generic function silc_socket_read and
2863 silc_socket_write (that used to be silc_packet_[read/write].
2864 The implementation of these are platform specific.
2866 * Added WIN32 specific routines of silc_socket_[read/write]
2867 to lib/silcutil/win32/silcwin32sockconn.c.
2869 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2871 * Added preliminary support for native WIN32 compilation under
2872 cygwin (using the -mno-cygwin option for GCC) to the
2873 ./configure.in.pre. The --with-win32 now prepares the
2874 compilation for native WIN32.
2876 * Rewrote the SILC Scheduler interface in the file
2877 lib/silcutil/silcschedule.h. The scheduler is now context
2878 based and does not have anymore any global static scheduler.
2879 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2880 and created lib/silcutil/win32 directory for WIN32 based
2883 * Added Unix specific network routines to the
2884 lib/silcutil/unix/silcunixnet.c and the old
2885 lib/silcutil/silcnet.c includes now only generic routines.
2887 Added WIN32 specific network routines to the
2888 lib/silcutil/win32/silcwin32net.c.
2890 * Added Unix specific utility functions from the
2891 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2893 * Added WIN32 SILC Scheduler to the file
2894 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2897 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2899 * Do not handle JOIN notify in the server if the target client
2900 is not registered (idata->registered == FALSE). The affected
2901 file is silcd/packet_receive.c.
2903 * Update the nickrec->founder in event_cumode in the Irssi SILC
2904 client. Affected file irssi/src/silc/core/silc-channels.c.
2906 * Fixed the CUMODE_CHANGE notify handling in the server when
2907 server and router are announcing their clients on channels.
2908 Now the mode changes are saved and notified correctly. The
2909 affected file is /silcd/packet_receive.c.
2911 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2912 They really did not replace the cache entry in the ID Cache.
2913 Now they do that. Affected file silcd/idlist.c.
2915 * Fixed the KICK notify handling in the Irssi SILC client to
2916 update the channel records so that the kicked client does not
2917 appear to be on the channel. The affected file is
2918 irssi/src/silc/core/silc-channels.c.
2920 * Always update the conn->current_channel when executing command
2921 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2923 * Fixed the KILL notify handling in Irssi SILC client to remove
2924 the killed client on all channels.
2926 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2928 * Fixed the silc_parse_command_line to remove extra spaces
2929 from the start and end of the arguments. Affected file is
2930 lib/silcutil/silcutil.c.
2932 * Cancel and free any active protocol in the function
2933 silc_server_close_connection. Affected file silcd/server.c.
2935 * Cancel and free any active protocol in the function
2936 silc_client_close_connction. Affected file is
2937 lib/silcclient/client.c.
2939 * Do not execute the KILL command for clients that are in
2940 history (ie. they are not in the network). Affected file is
2943 * Fixed KILL notify handling, client does not crash anymore.
2944 Affected file irssi/src/silc/core/silc-channels.c.
2946 * Reduced the default packet buffer size from 2048 to 1024 in
2947 lib/silccore/silcpacket.c.
2949 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2950 counter to the SKE context that is incresed when the SKE library
2951 performs async operation outside the library. If the outside
2952 process frees the SKE context and FREED status will be set
2953 and the library will detect after the sync operation that the
2954 libary is freed. The affected files are
2955 lib/silcske/silcske[_status].[ch].
2957 * Resolve the client entry information in the function
2958 silc_client_channel_message to assure that NULL pointer is not
2959 passed as client entry to the application. */
2961 * Fixed the task timeout calculation to assure that there is
2962 never negative timeouts. The affected file is
2963 lib/silcutil/silcschedule.c.
2965 * Fixed the channel user mode notification sending in server.
2966 It was sent point-to-point to the router (or to server by router)
2967 but it needs to be destined to a channel. The routines now
2968 supports sending the channel user mode notifys to the channels
2969 when announcing clients and channels. Affected files are
2970 silcd/server.c and silcd/packet_receive.c.
2972 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2973 It did not actually replace the old channel entry in the cache.
2974 Affected file lib/silcclient/client_notify.c.
2976 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2978 * Fixed a possible crash in silc_packet_send_prepare. It now
2979 assures always that there is enough space in the buffer and
2980 at the tail area of the buffer (for MAC).
2982 Fixed the inbound buffer reallocation in silc_packet_read.
2983 It was old code and did not handle the reallocation correctly.
2986 The affected file is lib/silccore/silcpacket.c.
2988 * Fixed buffer overflow in silc_parse_nickname in the file
2989 lib/silcutil/silcutil.c.
2991 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2993 * make install generates new server keys only if there is not
2996 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2998 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2999 Added check that if the NOREPLY is set then we will not send
3000 the away message. This avoids infinite loop of away messages
3001 if both clients are away. The affected file is
3002 lib/silcclient/client_prvmsg.c.
3004 * Fixed client crash if /NICK was given without arguments.
3005 Affected file lib/silcclient/command.c.
3007 * Server does not send the invite list in INVITE command back
3008 to the client if the list was not altered. Added this notion
3009 to the protocol spec as well. Affected file silcd/command.c.
3011 Fixed possible crash in INVITE command by checking the
3012 value of silc_server_get_client_route command.
3014 * Fixed the INVITE notify type handling. The arguments are now
3015 taken in correct order and client does not crash. The affected
3016 file is irssi/src/silc/core/silc-channels.c.
3018 Removed the "Inviting xxx to channel" message from the
3019 client library away and let the application handle it.
3020 Affected file lib/silcclient/command.c. Added that message
3021 to Irssi SILC client's message formats.
3023 * Fixed CMODE command crash in client. It now checks the
3024 amount of arguments correctly and does not crash. The affected
3025 file is lib/silcclient/command.c.
3027 * Do not create new channel automatically in silc_channels_join
3028 but check whether the channel by that name already exists.
3029 Affected file irssi/silc/core/silc-channels.c.
3031 * Do not send the SERVER_SIGNOFF to router if the disconnected
3032 entity was the router. Affected file silcd/server.c.
3034 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3035 SILC client as it was missing from there.
3037 Added the handling of the KICK notify to the Irssi SILC client
3038 as it was missing. Added "you have been kicked" message to
3039 Irssi SILC client's message modules formats.
3041 Added the handing of the KILL notify to the Irssi SILC client
3042 as it was missing. Added the kill message module formats
3045 The affected file is irssi/src/silc/core/silc-channels.c.
3047 * The router did not save the channel mode the server announced.
3048 Affected file silcd/packet_receive.c.
3050 * Fixed a possible crash in INFO command in server. If the
3051 server did not provide the server info it crashed. Affected
3052 file silcd/command.c.
3054 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3056 * Fixed the GETKEY command in the server to check also the
3057 global list. Otherwise the GETKEY would not work correctly
3058 in normal SILC server. Affected file silcd/command.c.
3060 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3062 * Fixed GETKEY crash, it crashed if the command did not succseed.
3064 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3066 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3067 is now real and not just an macro interface to GMP.
3069 Removed the entire GMP from the source tree and imported new
3070 NSS MPI library instead. Reason for removing GMP is that it is
3071 extremely large and compiles extremely slow. The NSS MPI
3072 is only a few files and compiles in less than 10 seconds.
3073 The speed is also about the same as GMP. The MPI is imported
3074 to lib/silcmath/mpi.
3076 If the system has GMP installed we will still use the GMP.
3077 If it is not then the NSS MPI will be compiled.
3079 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3081 * Merged a long nickname (127 characters long) crash bugfix from
3082 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3084 * Merged a freed memory reference bugfix from Irssi CVS tree.
3085 Affected file irssi/src/core/commands.c.
3087 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3089 * Added the server's public key sving and verification to the
3090 server when performing the SKE. This was missing and the
3091 remote server's (or router's) public key was accepted without
3092 checking whether we have it previously or trust it at all.
3093 Affected file silcd/protocol.c.
3095 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3097 * Check in the silc_server_timeout_remote if protocol is active
3098 and make sure that the protocol's final callback is called so
3099 that all memory if freed. Affected file silcd/server.c.
3101 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3103 * silc_server_whois_send_reply crashed the server if the nickname
3104 was 127 characters long. Affected file silcd/command.c.
3106 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3108 * Added sanity check to the silc_server_new_client. If the hostname
3109 is provided inside username then check that the provided hostname
3110 really is the same as the resolved one. If the hostname was not
3111 resolved then check it from the public key. Affected file is
3112 silcd/packet_receive.c.
3114 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3115 if the server disconnected us and the connection is not valid
3116 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3118 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3119 the library to the lib/silcutil/silcutil.[ch].
3121 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3123 * Close log file after open. Affected file
3124 lib/silcutil/silclog.c.
3126 * Check whether sock == NULL in silc_client_send_packet and return
3127 if it is. Affected file lib/silcclient/silcclient.c.
3129 * Check rec->entry == NULL in the Irssi SILC Client before
3130 sending the channel message. Affecte file is
3131 irssi/src/silc/core/silc-servers.c.
3133 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3135 * Merged a splitted window bugfix from Irssi CVS tree. The
3136 affected file is irssi/src/fe-text/textbuffer-view.c.
3138 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3139 It did not print nickname.
3141 * Improved the distributions system a bit.
3143 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3145 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3146 irssi/src/fe-text/gui-window.c.
3148 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3149 to in-active server. The affected file is
3150 irssi/src/silc/core/client_ops.c.
3152 * Resolve the client in USERS command reply if the entry does
3153 not have username resolved. The affected file is
3154 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3155 command to WHOIS command to really resolve stuff. The USERS
3156 is not used any more in any critical section so WHOIS can
3157 be used even though it might be slower than IDENTIFY.
3159 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3162 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3164 * Changed the protocol API a bit more consistent in the
3165 lib/silccore/silcprotocol.[ch].
3167 * Changed the following headers to ROBODoc format:
3169 lib/silccore/silcpayload.h
3170 lib/silccore/silcprotocol.h
3171 lib/silccore/silcsockconn.h
3173 All core library headers are now formatted.
3175 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3177 * Fixed a bug in Irssi SILC client; do not show that you are
3178 server/router operator if you really are not. Affected file is
3179 irssi/src/silc/core/client_ops.c.
3181 * Renamed silc_command_free_payload to silc_command_payload_free.
3182 Affected file lib/silccore/silccommand.h
3184 * Added silcmath.h to include the prototoypes of various routines
3185 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3188 * Changed the following headers to ROBODoc format:
3190 lib/silccore/silcchannel.h
3191 lib/silccore/silccommand.h
3192 lib/silccore/silcid.h
3193 lib/silccore/silcidcache.h
3194 lib/silccore/silcmode.h
3195 lib/silccore/silcnotify.h
3196 lib/silccore/silcpacket.h
3197 lib/silcmath/silcmath.h
3199 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3201 * Added checking to the server code not to start the server if
3202 ciphers and stuff are not configured properly. Affected files
3203 silcd/serverconfig.[h] and silcd/server.c.
3205 * Changed the layout of the header files of the public interfaces
3206 in the SILC libraries. The new layout supports ROBODoc
3207 documentation tool (and some others) so that it is easy to create
3208 a library reference manual. All the other headers and source
3209 code must still follow the CodingStyle document. Also source
3210 code must not include these ROBODoc stuffs, only the headers.
3211 Furthermore, all public interface headers must now be named
3212 by using `silc' prefix, example: silcapi.h, silccipher.h.
3213 Some files were renamed due to this. All the other headers
3214 must not be used as public interfaces. I will update the
3215 CodingStyle document later. Changed following headers, so far:
3217 lib/silcclient/silcapi.h
3218 lib/silccore/silcauth.h
3219 lib/silccore/silcprivate.h
3220 lib/silccrypt/silcdh.h
3222 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3226 * Removed silc_client_packet_send_flush from the client library
3227 as it is not needed. Affected file lib/silcclient/client.[ch].
3229 * Added printing of message of unresolved authentication method
3230 to the Irssi SILC client. Added it to the module formats.
3231 Removed the same message from the client library.
3233 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3235 * Added new distribution feature, DISTLABEL. Every distribution
3236 can define own preprocessor label that can be used in the
3237 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3238 file distributions, acconfig.h.pre and prepare.
3240 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3242 * Added Makefile.defines_int to include the actual definitions
3243 for Makefile.defines.in. Tested the new distribution system,
3244 created distributions and tested installation.
3246 * Added AWAY message printing to the Irssi SILC client. Added
3247 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3249 * Added SCONNECT command to call the SILC's CONNECT command.
3250 Cannot use CONNECT directly since Irssi uses that internally.
3251 Affected file irssi/src/silc/core/silc-servers.c.
3253 Added ACTION local command. It is same as ME command but takes
3254 the channel as mandatory argument.
3256 Rewrote some of the Irssi's help files to suite for SILC
3259 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3261 * Added Makefile.defines[.in] that should for now on be included
3262 in all Makefile.am file in the source tree. That file includes
3263 all common compilation definitions for SILC source tree.
3265 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3267 * Minor changes to the ./prepare script to change the package
3268 name according the distribution name to the configure.in.
3270 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3272 * Created new distribution system. Added file `distributions'
3273 that defines all the distributions that can be created out of
3274 the SILC source tree. The ./prepare script now reads that
3275 file to determine how to prepare the distributions. The
3276 first argument to the ./prepare is the name of the distribution
3277 and second is the version of the distribution. If given
3278 without arguments it creates the default (toolkit) distribution
3279 with the default version (defined in ./prepare).
3281 All Makefile.am files that are subject to the distributions
3282 are now named as Makefile.am.pre. These are ./Makefile.am
3283 and lib/Makefile.am. Others may be changed later.
3285 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3287 * Added invite list, ban list, some key management and connection
3288 error message printing to module formats in the Irssi SILC client.
3290 * Added new silc_client_set_away_message to set the away message
3291 that is back to the person who sent private message. The
3292 affected file lib/silcclient/silcapi.h and the
3293 lib/silcclient/client_prvmsg.c.
3295 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3297 * Fixed the private message sending in the Irssi SILC client,
3298 added local command KEY to the Irssi SILC client.
3300 Added key management and key agreement message formats to the
3301 irssi/src/fe-common/silc/module-formats.[ch].
3303 Added USERS (alias WHO) printing, server/router operator
3304 indication and LIST command printing to the module formats.
3306 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3308 * Fixed channel joining notify handling, cumode notify handling
3309 from Irssi SILC client.
3311 * Added SILC specific module-formats to the Irssi SILC client so
3312 that SILC specific message hilighting, colors etc is possible.
3313 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3315 Added channel mode, channel user mode, actions, notices,
3316 whois and whowas printing to the the module-formats.c.
3318 * Fixed a bug in channel deletion in the server. The channel
3319 is not left to the cache even if the channel founder auth mode
3320 is set when there are no users anymore on the channel. Affected
3321 file silcd/server.c.
3323 * The silc_net_localhost now resolves the entire hostname including
3324 the domain name. Affected file lib/silcutil/silcnet.c.
3326 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3328 * Changed the ask_passphrase client operation to be ascynchronous.
3329 It has now a completion callback and a context that the
3330 application must call after it has got the passphrase from
3331 the user. Affected files lib/silcclient/silcapi.h,
3332 lib/silcclient/protocol.c, lib/silcclient/command.c and
3335 Added SilcAskPassphrase callback that the application calls
3336 to deliver the passphrase to the library.
3338 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3339 The public key verification and especially a certificate
3340 verification is asynchronous procedure.
3342 Added new SILC_SKE_STATUS_PENDING status to indicate the
3343 request is pending and a callback will be called to finalize
3346 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3347 indicate that remote end did not send its public key (or
3348 certificate), even though we require it. Added check for this
3349 condition in the SKE. This was a security bug, now fixed.
3351 Defined new SilcSKEVerifyCbCompletion callback that is called
3352 when the verification process is completed.
3354 The affected files lib/silcske/silcske_status.h and
3355 lib/silcske/silcske.[ch].
3357 * Changed the verify_public_key client operation to be async
3358 as well. Defined SilcVerifyPublicKey callback that is used to
3359 indicate the success of the public key verification process.
3361 Changed the server and client to use the new async client
3364 * Changed the Irssi SILC client's internal scheduler to be called
3365 twice as many times as it used to be. As a result the client
3366 should be a bit faster now. Affected file is
3367 irssi/src/silc/core/silc-core.c.
3369 * Added support to Irssi SILC client of asynchronous public key
3370 verification and passphrase inquiry. Affected file is
3371 irssi/src/silc/core/silc-core.c.
3373 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3375 * Do not say "You have left channel %s" in client library.
3376 Moved it to the application. Affected files are
3377 lib/silcclient/command.c and silc/client_ops.c.
3379 * Fixed silc_client_get_clients. Command context was not
3380 duplicated and was freed memory in the callback. Affected
3381 file lib/silcclient/idlist.c.
3383 * Do not say "you are now talking..." on JOIN command in the
3384 client library. The appliation must handle it.
3386 * Do not say ".. changed topic to" in command reply in the
3387 client libary. The application must handle it.
3389 * Fixed TOPIC command sending in the client library.
3391 * Fixed a memory leak in silc_client_command_free in the file
3392 lib/silcclient/command.c.
3394 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3396 * Imported a modified version of Irssi client to the source tree.
3397 The Irssi will be used to create a new client called
3398 Irssi SILC. Imported to irssi/.
3400 Added silc_core_init_finish function to the Irssi. Affected
3401 file irssi/configure.in.
3403 A lot changes in the Makefile.ams around the irssi tree.
3405 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3407 * Do not rehash if the new size is same as the old size of the
3408 hash table, in the silc_hash_table_rehash*. The affected file
3409 lib/silcutil/silchashtable.c.
3411 * Replaced hash_table_del_by_context calls from the server
3412 (when channel->user_list and client->channels) to the
3413 hash_table_del as it is sufficient and faster.
3415 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3417 * Added silc_hash_table_list, silc_hash_table_get and the
3418 SilcHashTableList structure to provide an alternative way to
3419 traverse the hash table. The affected files are
3420 lib/silcutil/silchashtable.[ch].
3422 * Changed the server's idlist routines to use the hash table
3423 routines to optimize the code.
3425 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3427 * Replaced the client entry's `channel' list and channel entry's
3428 `user_list' list to hash tables for optimized lookup. Changed
3429 the code to use the hash table interface around the code.
3430 Affected file lib/silcd/idlist.[ch].
3432 * Added `auto_rehash' boolean argument to the function
3433 silc_hash_table_alloc to indicate whether the hash table should
3434 auto-rehash when it thinks is appropriate time. It will
3435 increase the hash table size if the there is twice as much
3436 entries in the table than the size of the table, and will
3437 decrease the size if there are twice as less entries than
3438 the size of the table.
3440 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3442 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3444 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3446 * silc_idcache_purge_by_context deletes the entry now by context
3447 as it is supposed to do. Affected file lib/silccore/idcache.c.
3449 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3450 client is not anymore valid (WHOWAS givens the info) and not
3451 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3453 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3455 * Removed the `data' and `data_len' arguments from the ID Cache
3456 interfaces and added `name' argument. ID Cache does not handle
3457 anymore the binary data only a names associated with given ID.
3459 * When hashing a Client ID with silc_hash_id the entire ID is
3460 not hashed anymore, instead only the hash of the Client ID is
3461 hashed. This way we can access the Client ID from the cache
3462 with Client ID but with the hash of the ID (which is a hash of
3463 the nickname) as well without any difference in performance.
3465 Added also silc_idcache_find_by_id_one_ext to do one on one
3466 searching when we have the actual ID. Added also function
3467 silc_hash_client_id_compare. The affected files are
3468 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3470 * When hashing the name associated with a ID it is always done
3471 in lowercase. This way we can access the cache without worrying
3472 about case-sensitivity, even though, for example nicknames are
3475 * Fixed a bug in server with channel message sending. It put
3476 wrong ID type as destination ID. The affected file
3477 silcd/packet_send.c.
3479 * silc_idcache_del_by_context now deletes from all hash tables
3480 by context. Affected file lib/silccore/idcache.c.
3482 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3484 * Changed the client library to use the new ID Cache interface.
3485 Changes around the source tree.
3487 * Added silc_hash_table_rehash_ext to rehash with specific
3488 hash function. Affected file lib/silcutil/silchashtable.[ch].
3490 * Added silc_hash_string_compare to compare two strings in the
3491 hash table. Affected file lib/silcutil/silcutil.[ch].
3493 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3495 * Added new function silc_idcache_del_by_context into the
3496 lib/silccore/idcache.[ch].
3498 * Changed the server's ID list routines to use the new ID Cache
3499 interface. Changes around the source tree.
3501 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3503 * Added silc_hash_table_del[_by_context]_ext functions in to the
3504 lib/silcutil/silchashtable.[ch].
3506 Removed silc_hash_table_find_all* routines and added new
3507 silc_hash_table_find_foreach to replace them.
3509 Added silc_hash_table_replace_ext function as extended
3510 replacing function. Separated the simple hash table interface
3511 from the extended hash table interface in the file
3512 lib/silcutil/silchashtable.h.
3514 * Fixed minor bugs and changed it to use some of the new
3515 hash table functions in lib/silccore/idcache.c
3517 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3519 * Added new function silc_hash_table_find_all to return all keys
3520 in the hash table by the specified key. As the hash table is
3521 collision resistant it also makes it possible to have several
3522 duplicate keys in the hash table. This function may be used to
3523 find all of the keys from the hash.
3525 Added user_context arguments to the SilcHashFunction,
3526 SilcHashCompare and SilcHashDestructor to deliver user specified
3529 Added new fuctions silc_hash_table_find[_all]_ext to do
3530 extended lookup with specified hash and compare functions and
3531 specified user contexts.
3533 Added new function silc_hash_table_add_ext to add the key
3534 with specified hash function and user context.
3536 Added new function silc_hash_table_foreach to traverse all
3537 entrys in the hash table. Added SilcHashForeach callback
3540 Added new function silc_hash_table_del_by_context to delete
3541 the entry only if the context associated with the key matches.
3543 Affected files are lib/silcutil/silchashtable.[ch].
3545 * Removed silc_hash_[server/client/channel]_id and added just
3546 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3547 silc_hash_id_compare to compare two ID's using as the hash table
3548 comparison function. Added also silc_hash_data to hash
3549 binary data and silc_hash_data_compare to compare it.
3551 * Removed silc_idlist_find_client_by_hash as it is not needed
3552 anymore. Affected file silcd/idlist.[ch].
3554 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3555 to use internally the SilcHashTable. The new ID Cache is a lot
3556 faster than the old one. Some of the ID Cache interface was also
3557 rewritten and obsolete and stupid functions were removed.
3559 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3561 * Added entry_count field to the SilcHashTable to keep the number
3562 of the entries in the table. Implemented the function
3563 silc_hash_table_rehash. Added new function
3564 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3566 Fixed a minor bug in silc_hash_table_free.
3568 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3569 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3570 into the lib/silcutil/silcutil.[ch].
3572 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Implemented a collision resistant hash table into the
3575 lib/silcutil/silchashtable[ch]. See the header and the source
3576 for the SilcHashTable API.
3578 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3580 * Merged dotconf version 1.0.2 into lib/dotconf.
3582 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3584 * Do not compile anything in lib/silcsim/* if the SIM support
3585 is not enabled. The tree should now compile without problems
3588 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3590 * Compiled the SILC under cygwin. Compiled and tested briefly
3591 without problems. More tests needed. The SIMs didn't compile
3594 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3596 * Fixed possible crash in silc_get_username in the
3597 lib/silcutil/silcutil.c.
3599 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3601 * Fixed a va_arg in silc/client_ops.c.
3603 * Oops, RC5 routines were named AES and caused some problems
3604 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3606 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3608 * Added new SilcIDIP structure into the lib/silccore/id.h and
3609 replaced the old `ip' fields from all SILC ID's to that type.
3610 This is a step towards IPv6 support.
3612 The silc_id_get_len takes now the ID as an extra argument.
3613 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3614 both IPv4 and IPv6 based ID's.
3616 The affected files are lib/silccore/id.[ch] and other files
3617 around the tree using these routines.
3619 * Removed the ID length arguments in server from various
3620 silc_server_send_notify_* routines -> they are not needed
3623 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * Fixed memory leak in silc_encode_pem_file in the file
3626 lib/silcutil/silcutil.c.
3628 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * Check minor version as well in the SKE. Affected files are
3631 silcd/protocol.c and lib/silcclient/protocol.c.
3633 * Added --identifier option to the server so that an identifier
3634 can be when creating the public key for the server. Affected
3635 file is silcd/silcd.c.
3637 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3638 lib/silccrypt/silcpkcs.c.
3640 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3642 * Register default ciphers and stuff when using -C option with
3643 the server. Affected file sildc/silcd.c.
3645 * Put back the servers public key filename format, it is better
3646 than the new one. For now, the client keys are saved with the
3647 new filename format. The affected file silc/client_ops.c.
3649 * Implemented the Cipher API for the rest of the ciphers that
3650 did not implement it or implemented it the wrong way.
3652 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3654 * Register default ciphers and stuff when using the -S option
3655 in the client. Affected file silc/silc.c. Same also when
3656 creating new key pair with -C option.
3658 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3660 * Fixed the silc_verify_public_key client operation function to
3661 save the public keys differently. The fingerprint is now
3662 used as filename and not the hostname. This way also the
3663 client keys are saved uniquely and not with hostnames. The
3664 affected file is silc/client_ops.c.
3666 * Trimmed the silc_hash_fingerprint function to remove extra
3667 whitespaces from the end of the fingerprint. The affected
3668 file is lib/silccrypt/silchash.c.
3672 * Added silc_cipher_register_default function to register all
3673 default ciphers. It can be used when configuration files
3674 does not exist and the application does not want any specific
3675 ciphers in any specific order.
3677 The SilcDList is now used as silc_cipher_list dynamically
3678 allocated cipher list. Removed the static list all together
3679 and now all ciphers must be allocated to the dynamic list.
3680 The silc_cipher_alloc routine was changed to check only the
3683 All silc_cipher_* routines that used to return int returns
3686 The affected files lib/silccrypt/silccrypt.[ch].
3688 * The same thing was done to silc_hash_* as for silc_cipher_*
3689 routines. Affected files lib/silccrypt/silchash.[ch].
3691 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3692 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3693 Added also silc_pkcs_[un]register[_default] functions.
3694 Removed the data_context from the PKCS API.
3696 * Added silc_hmac_register_default function to register default
3697 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3698 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3699 to unregister all hmacs at once.
3701 * Register the default ciphers, hash functions, PKCSs and HMACs
3702 if client's configuration file does not exist. The affected
3705 * The client did not load the hash functions from the SIM
3706 modules at all. Added support for this. Affected file is
3707 silc/clientconfig.c.
3709 * When decoding public key with silc_pkcs_public_key_decode, check
3710 the supported algorithm only if PKCS are registered. Affected
3711 file lib/silccrypt/silcpkcs.c. The same was done with the
3712 silc_pkcs_private_key_decode.
3714 * Fixed the SILC List routines to keep the list always in order.
3715 It used to change the list's order when traversing the list but
3716 not it preserves the order. Affected file lib/trq/silclist.h.
3718 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Added the client library to use the SilcSocketConnection's
3721 reference counter (by silc_socket_dup) to prevent the bug that
3722 the socket object may be freed underneath async operation.
3724 * The name resolv library checking fixes in the configure.in.pre.
3727 * Created new version of the protocol drafts for future
3728 development. The -03 drafts are the ones that will be changed
3729 in the trunk now and the -02 will remain as they are.
3731 * Send list of CUMODE notifys to the router when announcing
3732 the channel users to the router. Affected file silcd/server.c.
3733 If the router receiving channel founder CUMODE for a channel
3734 that already has channel founder it will send CUMODE notify
3735 to the sender to remove the channel founder rights from the
3736 announced client. Affected file silcd/packet_receive.c.
3738 * The CUMODE notify may now use Server ID as well as the entity
3739 who changes the mode. Updated protocool specs.
3741 * Updated INSTALL and README files.
3743 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3745 * New web pages in the http://silc.pspt.fi. The pages was
3750 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3752 * Implemented the [DenyConnectin] config section in the server.
3753 Added silc_server_config_denied_conn to check whether incoming
3754 connection is denied. Affected file silcd/serverconfig.[ch].
3756 * Do not check the ports when checking the incoming configuration
3757 data if the port is 0, meaning any. Affected file is
3758 silcd/serverconfig.c.
3760 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3762 * Fixed buffer overflow in silc_string_compare in the file
3763 lib/silcutil/silcutil.c.
3765 * Fixed double free in silc_server_command_leave in the file
3768 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3770 * Fixed the version checking in the server. Affected file is
3773 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Fixed the configuration data fetching when accepting new
3776 connections in the server. Affected file silcd/server.c.
3778 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3780 * Added `sender_entry' argument to the function
3781 silc_server_packet_relay_to_channel so that we can check
3782 whether some destination actually belongs to the same route
3783 the sender belongs (ie, we must not resend the packet to the
3784 sender). Affected file silcd/packet_send.[ch].
3786 * Added `servername' field to the SilcClientEntry in the server
3787 to hold the name of the server where client is from. Affected
3788 file is silcd/idlist.h.
3790 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Moved the channel message encrypting in the router betwen
3793 router connections from silc_server_channel_message to the
3794 silc_server_packet_relay_to_channel since we want to check
3795 whether we have anybody channel before encrypting anything.
3796 Affected files silcd/packet_[receive/send].c.
3798 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3800 * Fixed the [AdminConnection] server config section to support
3801 multiple entries. Affected file silcd/serverconfig.c.
3803 * Added support into the server to check the validity of the
3804 incoming connection before executing any KE or authentication
3807 * The connection configuration is now saved to the KE and
3808 connection auth protocol contexts and not fetched anymore in
3809 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3811 * The local hosts listenning address and port is also resolved
3812 now when starting the server. We want to have the socket object
3813 to include the real address and port for the listener. Added
3814 new function silc_net_check_local_by_sock into the files
3815 lib/silcutil/silcnet.[ch].
3817 * Fixed a broadcast bug in server -> do not broadcast if we
3820 * Fixed a routing bug. Do not route broadcast packets ever.
3821 Broadcast packets must be processed always and not routed since
3822 they may be destined to some other host than yourself and thus
3823 would get routed without no good reason. Affected file is
3826 * Added function silc_server_config_is_primary_route to check
3827 whether primary router connection has been configured (a router
3828 configuration that we are initiating). If there is not, we
3829 will assume that there is only two routers in the SILC network
3830 and we will use the incoming router connection as our primary
3831 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3833 * Changed the order of the broadcasting. Broadcast _after_ the
3834 packet has been processed not before. Affected file is
3837 * Fixed a [ClientConnection] parsing bug. The port was never
3838 parsed correctly thus resulting to port 0. Affected file
3839 silcd/serverconfig.c.
3841 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3842 argument and did not set the broadcast packet flag. Affected
3843 file silcd/packet_send.c. Fixed same bug in the function
3844 silc_server_send_notify as well.
3846 * If we receive NEW_ID packet for our own ID in the server, ignore
3849 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3853 * Removed the nickname from the Private Message Payload.
3854 Updated the code and the protocol specs.
3856 * Updated protocol specs for submitting to the IETF.
3858 * Tweaked the Random Number Generator a bit. Affected file
3859 lib/silccrypt/silcrng.c. Exported a new function
3860 silc_rng_[global]_add_noise which can be used to add more
3863 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3865 * Do not parse packets with different timeout when protocol
3866 is active -> may cause problem with rekey. Affected file
3869 * When server receives signoff notify it must not create
3870 new channel key if the client is on any channels since the
3871 sender of the signoff notify will create it.
3873 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3875 * Added printing of error messages during SKE protocol from the
3876 failure packet sent by server during SKE. Affected file
3879 * Removed the client's failure_callback handling with timeout
3880 and handle it immediately when received.
3882 * The SKE library returned wrong type in SUCCESS and FAILURE
3883 packets. They must be 32 bit MSB not 16 bit MSB.
3885 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3887 * Ok, rewrote the logic of the re-key and now it seems to work.
3888 I tested it on high traffic with frequent re-keys without
3889 problems. Added hmac_receive (and renamed hmac to hmac_send)
3890 in SilcClientConnection in lib/silcclient/client.h and
3891 in SilcIDListData in silcd/idlist.h. Also, removed the
3892 SilcPacketParserContext's cipher and hmac fields as they are
3893 not needed anymore and actually caused some problems when
3894 the ciphers and hmac's changed underneath the packet parser.
3896 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3898 * If re-key protocol is active then process the incoming packets
3899 synchronously since we must assure that icoming packets encrypted
3900 with the old key is processed before the new keys is set to
3901 use. This is true other packets than for REKEY packets.
3902 Affected file silcd/server.c. The same was done to client library
3903 as well, affected file lib/silcclient/client.c.
3905 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3907 * Fixed bug in client and server to accept the force send if
3908 the packet is send from silc_[server/client]_packet_process
3909 function. Otherwise the packets are never delivered, oops.
3911 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3913 * Disable force sending of packets when REKEY protocol is active.
3914 We must assure that no packet is sent directly when rekey is
3915 performed. All packets must be sent through packet queue.
3916 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3917 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3918 function is silc_[server/client]_packet_send_real to check
3921 * Replaced the SIM paths from example config files to
3922 /usr/local/modules. Also, make install creates now
3923 /usr/local/silc/logs directory to hold all the SILC server
3926 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3928 * Made the configure.in.pre work on Solaris. Patch by salo.
3930 * Made all ciphers compatible with non-x86 machines. Defined
3931 CBC mode macros into lib/silccrypt/ciphers_def.h.
3933 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3935 * Fixed the make install.
3937 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3939 * When MAC computation fails the silc_packet_decrypt returned 0
3940 even though it was supposed to return -1. Fixed this. The
3941 affected file is lib/silccore/silcpacket.c.
3943 * Do not replace the config files in /etc/silc (in make install)
3944 if they already exist. Affected file ./Makefile.am.
3946 * Do not send re-key packets immediately but through packet queue.
3947 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3949 * Changed silc_net_check_host_by_sock to return FALSE if the
3950 IP/DNS could not be resolved. Though, it returns the IP address
3951 now even if it could not resolve it (but returns also FALSE).
3952 Affected file lib/silcutil/silcnet.[ch].
3954 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3956 * Added silc_pkcs_decode_identifier to decode the public key's
3957 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3958 Added also silc_pkcs_free_identifier. Added also new context
3959 SilcPublicKeyIdentifier.
3961 * Added -S option to the silc client. It is used to dump the
3962 contents of the specified public key file.
3964 * Changed the PKCS api to return the public key length when
3965 setting the public key.
3967 * Fixed a fatal bug in the public and private key file loading.
3968 Affected file lib/silccrypt/silcpkcs.c.
3970 * Execute the packet parsing for client with zero (0) timeout
3971 if the protocol is active. Affected file silcd/server.c.
3973 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3975 * Made the key generation options to the silcd program. Added
3976 -C option, equivalent to client's option.
3978 * Added new [ServerKeys] config section to the server. It
3979 configures the server's public and private key.
3981 * Defined generic Public Key Payload into the protocol
3982 specification to send specific type of public keys and
3985 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3986 public key or certificate.
3988 * Implemented the GETKEY command to the server and to the
3989 client library and on user interface.
3991 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3993 * Made preliminary `make install' work.
3995 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3997 * Added SilcServerRekey context into silcd/idlist.h.
3999 * Added the PFS support as defined in the specification to the
4000 SKE protocol. Affected files lib/silcske/*.c.
4002 * Added `ske_group' field to the SilcServerRekey context to hold
4003 the number of the SKE group that is used with PFS in re-key.
4004 Affected file silcd/idlist.h.
4006 * Added PFS re-key support to the server. Affected file is
4009 * Added silc_protocol_cancel to cancel execution of the next
4010 state of the protocol. Affected file is
4011 lib/silccore/silcprotocol.[ch].
4013 * Added the re-key support with and without PFS to the client
4014 library. Re-key is performed once in an hour, by default.
4016 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4017 Added silc_client_rekey_callback and silc_client_rekey_final.
4018 Affected files are lib/silcclient/protocol.[ch] and
4019 lib/silcclient/client.[ch].
4021 * Removed the `hmac_key' and `hmac_key_len' fields from the
4022 SilcClientConnection structure; not needed. Affected file is
4023 lib/silcclient/client.h.
4027 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4029 * Do not ask whether user wants to use the negotiated private key
4030 for private messages, just use it. Affected file is
4031 silc/local_command.c.
4033 * Added `send_enc_key' and `enc_key_len' fields to the
4034 SilcIDListData structure since they are needed in the re-key
4035 phase. Affected file is silcd/idlist.[ch].
4037 * Implemented the simple re-key protocol into the server.
4038 Affected files silcd/server.c and silcd/protocol.[ch]. The
4039 re-key will be performed once in an hour, by default.
4041 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4042 Added silc_server_rekey, silc_server_rekey_callback and
4043 silc_server_rekey_final.
4045 * Removed Tunneled flag from the protocol. Updated the code
4046 and the specifications.
4048 * Adde `pfs' field to the SilcIDListData to indicate whether
4049 the PFS is to be performed in the re-key. Affected file is
4052 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4054 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4055 int64 of at least the xintXX size. If void * is less that 4
4056 bytes uint32 * will be used. Defined bool as boolean.
4058 * Changed _ALL_ unsigned long and unsigned int to uint32,
4059 unsgined short to uint16 in the source tree.
4061 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4062 not handle clients that has entry->data.registered == FALSE.
4063 They are not in the network anymore. Affected file is
4066 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Implemented the sending of the SERVER_SIGNOFF notify in the
4069 server. Affected file is silcd/server.c.
4071 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4072 Added also silc_notify_payload_encode_args into the
4073 lib/silccore/silcnotify.[ch].
4075 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4076 Affected file silcd/packet_receive.c.
4078 * Implemented the SERVER_SIGNOFF notify handling in the client
4079 library. Affected file lib/silcclient/client_notify.c. Also,
4080 implemnted the printing of the SERVER_SIGNOFF info to the
4081 application. Affected file silc/client_ops.c.
4083 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4084 if the deleting was successful. Affected file silcd/idlist.[ch].
4086 * Added support for public key authentication in the connection
4087 authentication protocol in the client library. Affected file
4088 lib/silcclient/protocol.c.
4090 * Changed the server's silc_idlist_get_clients_by_* interface
4091 to support already allocated array so that new entries may be
4092 added to pre-allocated array. Affected file silcd/idlist.[ch].
4093 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4094 and command replies.
4096 * All command reply functions in the server now calls the
4097 pending command callback even if error occured. This way the
4098 error will be delivered to the client as well. Affected files
4099 silcd/command.c and silcd/command_reply.c.
4101 * Fixed INFO command to return local server's info if no server
4102 was provided. Affected file lib/silcclient/command.c.
4104 * Removed RESTART command for good. Updated the code and the
4107 * Rewrote parts of the task system. It is a bit simpler now.
4108 Removed unsued task priorities. The affected files are
4109 lib/silcutil/silctask.[ch].
4111 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4113 * Moved the USERS printing from the library to the application.
4114 Affected files lib/silcclient/command.c and silc/client_ops.c.
4116 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4120 * Added channel key re-key support. The re-key is perfomed
4121 only by the router and is done once in an hour. Added `rekey'
4122 field to the SilcChannelEntry in the server. Affected files
4123 silcd/server.c and silcd/idlist.h.
4125 * Added silc_task_unregister_by_context into the file
4126 lib/silcutil/silctask.[ch].
4128 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Added SILC_UMODE_GONE mode to indicate when the client is not
4131 present in the SILC network. Added also support to the local
4132 command AWAY that will set this mode. Added support of showing
4133 "xxx is gone" in WHOIS command. The USERS command shows the
4134 gone status as well.
4136 * Fixed setting server and router operator privileges in the
4137 server's UMODE command. Affected file silcd/command.c.
4139 * Merged the SKE KE1 and KE2 payloads into one payload. The
4140 new KE payload is equivalent to the old KE2 payload.
4142 Cleaned up the SKE Start Payload parsing. It now uses the
4143 simple buffer unformatting to do the parsing. A lot faster
4146 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4147 to the SKE that is used to indicate whether both of the SKE
4148 parties should perform authentication. By default only the
4149 responder performs authentication. By setting this flag also
4150 the initiator must do authentication. By default it is unset
4151 since in normal SKE case, client to server connection, only
4152 the responder should do authentication. When doing SKE between
4153 two clients both should perform authentication. Updated the
4154 code and the protocol specs.
4156 * A little fix to IDENTIFY command in the server. Search the
4157 client first by hash not nickname. Affected file is
4160 * Fixed the silc_client_close_connection to support closing
4161 the client to client connections wihtout deleting too much
4162 data. Affected file lib/silcclient/client.c.
4164 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4165 are received if protocol used to be active but is not anymore
4166 the application would crash due to NULL pointer dereference.
4167 Affected files silcd/server.c and lib/silcclient/client.c.
4169 * Added `hash' field to the SilcClientConnection to include
4170 the hash function negotiated in the SKE protocol.
4172 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4173 to set the channel founder authentication data. A client can
4174 claim the founder rights later by providing the authentication
4175 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4176 This way the channel founder can regain the channel founder
4177 privileges even it is left the channel. This works only on
4178 local server and the client must be connected to the same
4179 server to be able to regain the founder rights. Updated the
4180 protocol specs accordingly.
4182 Added support to the CMODE command in the client to set the
4183 founder auth data. Read the README to see how to set it.
4185 Added support to the CUMODE command to claim the founder
4186 rights. Read the README to see how to do it.
4188 Added support for the founder authentication to the Channel
4189 Entry in the server. Affected file silcd/idlist.h.
4191 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4192 server's CMODE command. Affected file silcd/command.c.
4194 * Added the following new functions into lib/silccore/silcauth.[ch]:
4195 silc_auth_get_method and silc_auth_get_data.
4197 * The server now saves the remote hosts public key to the
4198 SilcIDListData pointer. Affected file silcd/protocol.c.
4200 * The normal server now does not remove the channel entry from
4201 the cache if the founder authentication data is set. It used
4202 to remove it if the founder was the last one on the channel on
4203 the server and left the channel. The auth data is saved and
4204 if the channel is re-joined later the old entry is used with
4205 the old auth data. Affected files silcd/command_reply.c and
4208 * Removed the `pkcs' field from the SilcIDListData structure
4209 in the server; it is not used. Affected file silcd/idlist.h.
4211 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4213 * Fixed packet processing on slow links. Partial packets were
4214 never re-processed because the incoming data buffer was cleared
4215 by the application. Application must not directly clear the
4216 sock->inbuf, the packet processing routines handle it. Fixed
4217 this in client library and in server.
4219 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4221 * Fixed the WHOIS and IDENTIFY send reply function to really
4222 check whether to send list or just one entry. Affected file
4225 * Cleaned up the LEAVE command's channel key distribution. The
4226 affected file silcd/command.c.
4228 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4229 can enforce the channel mode as well. In that case the ID
4230 includes the ID of the server. The code now enforces the
4231 mode change if the router have different mode than the server.
4233 * The notify client operation with CMODE_CHANGE notify can now
4234 return NULL client_entry pointer if the CMODE was not changed
4235 by client. Application must check for this.
4237 * Added <Server ID> argument to INFO command to support server
4238 info fetching by Server ID.
4240 * Added silc_server_announce_get_channel_users to get assembled
4241 packets of channel users of the specified channel. Affected
4242 file silcd/server.[ch].
4244 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4245 was freed underneath the ID Cache.
4247 * Re-announce clients when the server received CHANNEL_CHANGE
4248 notify from the router. Affected file silcd/packet_send.c.
4250 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4252 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4253 crashed since it did not handle the fact that there is no cipher
4254 called "3" and didn't check the error condition. Now fixed.
4256 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4257 flag. It can be used to send message requests.
4259 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4261 * Implemented the RESTART command in the client.
4263 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4264 notice type messages. Added notice printing to the user
4267 * The channel keys are not re-generated if the channel's mode
4268 is PRIVKEY, ie private key on the channel exists. Affected
4269 files silcd/server.c and silcd/command.c.
4271 * Fixed a little bug in channel message delivery when channel
4272 private keys are set in the server. Affected file is
4273 silcd/packet_send.c.
4275 * Changed the setting on channel->on_channel = TRUE from the
4276 silc_client_save_channel_key to the JOIN command reply. The
4277 key payload is not received if the private channel key is set.
4278 Affected file lib/silcclient/command_reply.c and the
4279 lib/silcclient/client_channel.c.
4281 * When the CMODE_CHANGE notify is sent and the channel private
4282 key mode is removed the channel key must be re-generated in
4283 other cells as well. Added this support for the router in the
4284 silcd/packet_receive.c.
4286 * Added new local command NOTICE to send notice message on
4287 channel. Affected file silc/local_command.[ch].
4289 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4291 * Added new local command ME to the client. It is used to send
4292 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4293 some action. Affected file silc/local_command.[ch].
4295 * Changed channel_message and private_message client operations
4296 to deliver the message flags to the application. Added also
4297 the `flags' arguments to the silc_client_send_channel_message
4298 and silc_client_send_private_message functions. Affected file
4301 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4303 * Redefined the Private Message Payload to support private message
4304 keys and to support the new private message flags. Updated
4305 the protocol specs. Flags makes it possible to have for example
4306 CTCP style messages.
4308 * Added new type SilcPrivateMessagePayload and defined an API
4309 for it in the lib/silcclient/silcprivate.[ch].
4311 * Tested private message private keys successfully. Tested the
4312 private message key set, unset and list commands with the new
4315 * Redefined the Channel Message Payload to include the channel
4316 message flags (equal with private message flags) to support
4317 for example CTCP style messages.
4319 * Defined some of the message (for channel and private message)
4320 flags. Updated the protocol specs and added the flags to the
4321 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4323 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Added SilcKeyAgreementStatus type to the key agreement routines
4326 to indicate the current status and error if one occured.
4327 The status types are defined in the lib/silcclient/silcapi.h.
4329 * Added new local command KEY that is used to set and unset private
4330 keys for channels, set and unset private keys for private messages
4331 with remote clients and to send key agreement requests and
4332 negotiate the key agreement protocol with remote client. The
4333 key agreement is supported only to negotiate private message keys,
4334 it currently cannot be used to negotiate private keys for channels,
4335 as it is not convenient for that purpose.
4337 * Fixed a minor pending callback setting bug in the function
4338 silc_client_get_client_by_id_resolve, now the function works.
4339 Affected file lib/silcclient/idlist.c.
4341 * Added function silc_net_get_local_port to get local bound
4342 port by socket. Added to lib/silcutil/silcnet.[ch].
4344 * Added `sockets' and `sockets_count' fields to the SilcClient
4345 object. They hold the sockets of the listenning sockets in
4346 the client. Listenning sockets may be for example the key
4347 agreement server. Affected file lib/silcclient/client.[ch].
4348 Added functions the silc_client_add_socket and the
4349 silc_client_del_socket. They are exported to the application
4352 * Added ~./silc/clientkeys to support other client's public keys.
4354 * Renamed verify_server_key client operation to verify_public_key
4355 and added one argument to indicate the type of the connection
4356 (server, client etc.).
4358 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Added silc_server_connection_auth_request to handle the
4361 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4362 silcd/packet_receive.[ch].
4364 * Added silc_server_send_connection_auth_request into the
4365 silcd/packet_send.c to send the connection auth request packet.
4367 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4370 * Fixed the public key authentication in responder side in the
4371 server. The `auth_data' pointer includes the SilcPublicKey
4372 not the path to the public key. Affected file silcd/protocol.c.
4374 * Implemented the public key authentication in the initiator side
4375 in the server. Affected file silcd/protocol.c.
4377 * Removed the [RedirectClient] config section from the server
4378 configuration. Is not needed and I don't want to implement it.
4380 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4382 * Cleaned up the CMODE command in the server. It now works
4383 correctly and supports all the modes defined in the protocol.
4384 Affected file is silcd/command.c.
4386 * Added `hmac_name' field to the SilcChannelEntry in the server
4387 to hold the default HMAC of the channel. It can be set when
4388 creating the channel (with JOIN command). Affected files
4391 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4392 type to indicate the change of the current cipher and hmac
4393 on the channel. Client can safely ignore the <cipher> argument
4394 (if it chooses to do so) since the CHANNEL_KEY packet will
4395 force the channel key change anyway. The <hmac> argument is
4396 important since the client is responsible of setting the new
4397 HMAC and the hmac key into use.
4399 * Fixed the CMODE command in the client library as well.
4401 * Tested CMODE command in router environment successfully.
4403 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4405 * Show the version of the remote client (or server) when connecting
4406 to the server. It is logged to the log file. Affected file
4407 is silcd/protocol.c.
4409 * Fixed the KILLED notify handling in the client library. The
4410 client must be removed from all channels when receiving the
4413 Also, do not remove the client entry when giving the KILL
4414 command but when the KILLED notify is received.
4416 * Removed silc_idlist_find_client_by_nickname from the server.
4417 Not needed anymore. Affected files silcd/idlist.[ch].
4419 * Implemented the CHANNEL_CHANGE notify type handling to the
4420 server. Affected file silcd/server.c.
4424 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4426 * Added silc_server_send_notify_invite to send the INVITE
4427 notify between routers.
4429 * Implemented the INVITE command correctly to the server.
4431 * Implemented the INVITE notify type handling in the server.
4433 * Implemented the INVITE command to the client library and on the
4436 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4438 * Added function silc_server_get_client_resolve to find the
4439 client entry by ID from all ID lists and then resolve it
4440 (using WHOIS) if it cannot be found. Affected file is
4443 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4445 * Implemented the BAN command to the client library.
4447 * The JOIN command in the server now checks the invite list
4450 * Changed the silc_command_reply_payload_encode_va and the
4451 silc_command_payload_encode_va to support that if argument is
4452 NULL it ignores and checks the next argument. Affected file
4453 lib/silccore/silccommand.c.
4455 * Added silc_server_send_notify_ban to send the BAN notify
4456 type between routers.
4458 * Chaned the silc_notify_payload_encode to support that if
4459 argument is NULL it ignores and checks the next argument.
4460 Affected file lib/silccore/silcnotify.c.
4462 * Tested ban lists in router environment successfully.
4464 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4466 * Implemented BAN command to the server, in silcd/command.[ch].
4468 * Removed the BAN and INVITE_LIST modes from the CMODE command
4471 * Added function silc_string_match to regex match two strings.
4472 Affected files lib/silcutil/silcutil.[ch].
4474 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4476 * Redefined parts of the SilcChannelEntry in the server to support
4477 the new ban and invite lists.
4479 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Redefined the INVITE command. The same command can be used to
4482 invite individuals to the channel but also to manage the invite
4483 list of the channel (to add to and remove from the invite list).
4484 Updated the protocol specs.
4486 * Added new command SILC_COMMAND_BAN that can be used to manage
4487 the ban list of the channel. Updated the protocol specs.
4489 * Removed the channel modes: the SILC_CMODE_BAN and the
4490 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4491 in the CMODE command. The equivalent features are now available
4492 using INVITE and BAN commands. Updated the protocol specs.
4494 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4495 in the network about change in the current ban list. The notify
4496 type is not used by the client.
4498 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4499 support the invite lists.
4501 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4503 * Added new function silc_string_regexify that converts string
4504 including wildcard characters into regex string that can
4505 be used by the GNU regex library. Added into the file
4506 lib/silcutil/silcutil.[ch].
4508 Added silc_string_regex_combine to combine to regex strings
4509 into one so that they can be used as one regex string by
4510 the GNU regex library. Added into the file
4511 lib/silcutil/silcutil.[ch].
4513 Added silc_string_regex_match to match two strings. It returns
4514 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4516 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4518 * Imported GNU regex to the soruce tree into lib/contrib.
4519 Fixed some compiler warning from the regex.c.
4521 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4523 * Fixed MOTD command in the server to work in router environment.
4525 * Fixed the MOTD command in the client library to support
4526 the server argument in the command.
4528 * Added `nickname_len' argument to the silc_idlist_add_client
4529 in the server, as the `nickname' argument may be binary data
4532 * Added silc_idlist_get_channels to return all channels from
4535 * Implemented LIST command to the server. Affected file is
4538 * Implemented the LIST command to the client library and on the
4541 * Added [<user count>] argument to the LIST command reply.
4542 With private channels the user count is not shown.
4544 * Updated TODO and README.
4546 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4548 * The client entry's data.registered must be TRUE even with
4549 global client entry on global client list. The data.registered
4550 is used to check whether the client is anymore in the network,
4551 for example with WHOWAS command so it must be valid.
4553 * Fixed the WHOWAS command in the server. It now actually works
4554 in router environment. Added function into silcd/command_reply.c
4555 silc_server_command_reply_whowas_save.
4557 * Added silc_idlist_purge function to the silcd/idlist.c
4558 to periodically purge the ID Cache.
4560 * Fixed INFO command in the server. It works now in router
4561 environment. Added <server name> argument to the INFO command
4562 reply. Updated the protocol specs.
4564 * Fixed minor bug in silc_idcache_purge to not purge if the
4565 expire value is zero.
4567 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4568 they were buggy because of the WHOWAS information.
4570 * Fixed local command MSG to handle the async resolving of
4571 the remote client properly. It used to fail the first MSG.
4572 Affected file silc/local_command.c.
4574 * Added `data_len' field to SilcIDCache context.
4576 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4578 * Update TODO. Todo in commands in the server.
4580 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4582 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4583 used by routers as broadcast packet to inform other routers
4584 about the changed user mode.
4586 Implemented the notify handling in the server. Affected file is
4587 silcd/packet_receive.c. Added the function
4588 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4590 * Added new generic Channel Payload and deprecated the New Channel
4591 Payload. The New Channel Payload is now the generic Channel
4594 * Added new argument `mode' to the silc_server_send_new_channel
4595 as it is required in the Channel Payload now.
4597 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4598 and created a new and real SilChannelPayload to represent the
4599 new generic Channel Payload. Implemented the encode/decode
4600 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4602 * Added silc_server_get_client_channel_list to return the list
4603 of channels the client has joined for WHOIS command reply.
4604 Affected file silcd/server.[ch].
4606 * Implemented the channel list sending in the WHOIS command reply
4607 in server and in the client.
4609 Implemented the channel list displaying on the user interface
4610 as well. Affected file silc/client_ops.c.
4612 * Added silc_channel_payload_parse_list to parse list of Channel
4613 Payloads. It returns SilcDList list of SilcChannelPayloads.
4614 Client for example can use this function to parse the list of
4615 channels it receives in the WHOIS command reply. The caller
4616 must free the list by calling silc_channel_payload_list_free.
4617 Affected files lib/silccore/silcchannel.[ch].
4619 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4621 * Added one new argument <user mode> to the WHOIS command reply
4622 to return the mode of the user in SILC. Updated the protocol
4625 Implemented it to the server and client.
4627 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4629 * Fixed the mode printing on the user interface on joining.
4630 Affected file silc/client_ops.c.
4632 * Implemented the UMODE command and user modes in general to the
4633 client library and to the user interface.
4635 * Implemented the UMODE command to the server.
4637 * The server now sends UNKNOWN_COMMAND error status if client sends
4638 unknown command. Affected file silcd/command.c.
4640 * All server commands now handle the command identifier the right
4641 way when sending the command reply to the client. The client can
4642 use to identify the command replies with the identifier.
4644 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4646 * Added silc_server_get_client_route to resolve the route to
4647 the client indicated by the client ID. Affected file is
4650 * Added silc_server_relay_packet as general function to relay
4651 packet to arbitrary destination. This deprecates functions
4652 like _send_private_message_key, _relay_notify etc. Affected
4653 file is silcd/packet_send.[ch].
4655 Removed silc_server_send_key_agreement,
4656 silc_server_send_private_message_key and
4657 silc_server_packet_relay_notify functions from the file
4658 silcd/packet_send.[ch].
4662 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4663 server. Affected file silcd/packet_receive.[ch].
4665 * Implemented the KILL command to the client. Implemented the
4666 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4667 Affected files lib/silcclient/command[_reply].c and
4668 lib/silcclient/client_notify.c. Implemented the KILL notify
4669 printing in the user inteface.
4671 * Fixed a lot silc_parse_nick memory leaks from the client
4672 library in the file lib/silcclient/command.c.
4674 * Changed the silc_server_send_notify_on_channels's `sender'
4675 argument from SilcSocketConnection to SilcClientEntry to
4676 check the sender as entry and not as connection object and not
4677 to send to the client provided as argument. The affected file
4678 is silcd/packet_send.[ch].
4680 * The notify packets that are destined directly to the client used
4681 to not to be processed by the server. Now changed that and the
4682 server processes all notify packets. After relaying the packet
4683 to the client the notify packet is processed in the server.
4685 * The silc_server_free_client_data now checks whether there is
4686 pending outgoing traffic for the client and purges the data to
4687 the network before removing the client entry.
4689 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4691 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4692 an client is killed from the SILC Network. Updated the protocol
4695 Added new function silc_server_send_notify_killed to the
4696 silcd/packet_send.[ch].
4698 * Added function silc_server_packet_relay_notify to relay notify
4699 packets that are destined directly to a client. In this case
4700 the server does not process the notify packets but merely relays
4701 it to the client. Affected file silcd/packet_send.[ch].
4703 Added also silc_server_packet_process_relay_notify to check
4704 whereto relay the notify. Affected file is
4705 silcd/packet_receive.[ch].
4707 * Implemented the KILL command to the server.
4711 * Added the backup schema desgined last fall to the protocol
4712 specs for everyone to see. The specification is in the
4713 *-spec-xx.txt draft and the packet type definitions for the
4714 backup routers is in *-pp-xx.txt draft. Thusly, added also
4715 new packet type SILC_PACKET_CELL_ROUTERS.
4717 * A big security problem in the implementation discovered. The
4718 signoff of an client did not cause new channel key generation
4719 which it of course should've done. The channel keys must be
4720 always re-generated when client leaves (or signoffs) the channel.
4721 The silc_server_remove_from_channels funtion now handles
4722 the channel key re-generation.
4724 * Added `sender' argument to the silc_server_send_notify_on_channels
4725 to not to send the client provided as argument. Affected file
4726 silcd/packet_send.[ch].
4728 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Implemented OPER and SILCOPER commands into the server and
4733 * Added silc_auth_verify and silc_auth_verify_data to verify
4734 the authentication directly from the authentication payload.
4735 It supports verifying both passphrase and public key based
4736 authentication. Affected file lib/silccore/silcauth.[ch].
4738 * Added `hash' field to the SilcIDListData structure. It is the
4739 hash negotiated in the SKE protocol. Affected file is
4742 * Slight redesigning of the SilcAuthPayload handling routines.
4743 Do not send SilcPKCS but SilcPublicKey as argument.
4745 * Implemented the public key authentication support to the
4746 serverconfig. The public key is loaded from the provided path
4747 and saved as authentication data to void * pointer. Thus,
4748 changed the unsigned char *auth_data to void *auth_data;
4750 * Fixed SHUTDOWN command to send the reply before the server
4751 is shutdown. :) Affected file silcd/command.c.
4753 * Fixed fatal bug in CONNECT command. The hostname was invalid
4754 memory and server crashed. Affected file silcd/command.c.
4756 * Fixed fatal bug in CLOSE command. The server_entry became
4757 invalid but was referenced later in the command. Affected file
4760 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4762 * Fixed fatal bug in failure packet handling. Server ignored
4763 the failure and thus crashed when it came.
4767 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4769 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4770 that the command may be executed only once in (about) 2 seconds.
4771 The old SILC_CF_LAG flag is same but allows command bursts up
4772 to five before limiting.
4774 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4775 server code. Various commands now includes the CF_LAG_STRICT
4776 flag to disallow any kind of miss-use of the command.
4778 * Fixed the silc_buffer_unformat to not to allocate any data
4779 if the length of the data is zero. It used to allocate the
4780 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4782 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4784 * Changed the format of AdminConnection configuration section
4785 in the server. Added username of the admin to the format.
4786 Affected files silcd/serverconfig.[ch].
4788 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4789 to return admin configuration data by host, username and/or
4792 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4794 * Implemented WHOWAS command to the server. Added the functions:
4796 silc_server_command_whowas_parse,
4797 silc_server_command_whowas_send_reply,
4798 silc_server_command_whowas_from_client and
4799 silc_server_command_whowas_from_server
4801 * Added <Client ID> argument to the WHOWAS command reply. Updated
4802 the protocol specs accordingly.
4804 * Implemented WHOWAS command and command_reply to the client
4807 Implemented the WHOWAS printing on the user interface.
4809 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4811 * Added new argument to the WHOWAS command reply, the real name.
4812 It is an optional argument. Updated the protocol specs.
4814 * Added SilcIDCacheDestructor callback that is registered when
4815 the SilcIDCache is allocated. The callback is called when
4816 an cache entry in the ID Cache expires, or is purged from the
4817 cache. Added into lib/silccore/idcache.[ch].
4819 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4820 to destruct the client entries when the cache entry expires.
4821 Other ID Cache's in server and in the client library ignores
4824 * If the ID Cache entry's `expire' field is zero then the entry
4825 never expires. Added boolean `expire' argument to the
4826 silc_idcache_add function in the lib/silccore/idcache.[ch].
4827 If it is TRUE the default expiry value is used.
4829 * Added silc_server_free_client_data_timeout that is registered
4830 when client disconnects. By default for 5 minutes we preserve
4831 the client entry for history - for WHOWAS command.
4833 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4835 * Added support to the server to enforce that commands are not
4836 executed more than once in 2 seconds. If server receives
4837 commands from client more frequently, timeout is registered
4838 to process the commands. Affected file silcd/command.c.
4839 Added new function silc_server_command_process_timeout.
4841 * Changed NICK_NOTIFY handling in client library to check that
4842 if the client's nickname was changed, so there is no need to
4843 resolve anything from the server.
4845 * Removed error printing from the WHOIS and IDENTIFY commands.
4846 If error occurs then it is ignored silently in the client library.
4847 The application, however, may map the received error to
4848 human readable error string. The application currently maps
4849 the NO_SUCH_NICKNAME error to string.
4851 * Made the command status message public to the application. Moved
4852 them from lib/silcclient/command_reply.c to
4853 lib/silcclient/command_reply.h. The application can map the
4854 received command status to the string with the
4855 silc_client_command_status_message function.
4857 * Added check to the server to check that client's ID is same
4858 as the Source ID in the packet the client sent. They must
4861 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4863 * Added dist-bzip hook to the Makefile.am to make bzip2
4864 compressed distributions.
4866 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4868 * Server now enforces the maximum length for the nickname and
4869 the channel as protocol specification dictates. 128 bytes for
4870 nickname and 256 bytes for channel name.
4872 * Moved the WHOIS printing to the application. The client libary
4873 does not print out the WHOIS information anymore, the application
4874 must do it. Renamed silc_client_command_reply_whois_print to
4875 the silc_client_command_reply_whois_save.
4877 The client's idle time is also sent to the application now, and
4878 the idle is shown on screen.
4880 * Added silc_client_command_reply_identify_save to save the
4881 received IDENTIFY entries.
4883 * Do not check for channel private keys in message sending and
4884 reception if the channel does not have the PRIVKEY mode set.
4885 Affected file lib/silclient/client_channel.c.
4887 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4889 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4890 just surfaced after chaning the JOIN procedure.
4892 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4894 * Added silc_client_get_clients_by_list to get client entries
4895 from Client ID list, that is returned for example by JOIN
4896 and USERS command replies. The application should use this
4897 function for example when JOIN command reply is received to
4898 resolve the clients already on the channel (library does not
4899 do that anymore as USERS command reply is not used in the JOIN
4900 procedure anymore). Affected files lib/silcclient/silcapi.h and
4901 lib/silcclient/idlist.c.
4903 * JOIN command reply and USERS command reply returns now SilcBuffer
4904 pointers instead of unsigned char pointers when returning
4905 the client list and mode list.
4907 * Added <Client ID> argument to the JOIN command reply, mainly
4908 for the server to identify for which client the command was
4909 originally sent. Updated protocol specs accordingly.
4911 * Added SilcDlist private_key pointer to the SilcChannelEntry
4912 in the client to support the channel private keys. Affected
4913 file is lib/silcclient/idlist.h.
4915 * Added SilcChannelPrivateKey argument to the function
4916 silc_client_send_channel_message so that application can choose
4917 to use specific private ke if it wants to. If it is not provided,
4918 the normal channel key is used, unless private keys are set.
4919 In this case the first (key that was added first) is used
4920 as the encryption key.
4922 * Implemented the support for channel private key handling.
4923 Implemented the following functions:
4925 silc_client_add_channel_private_key,
4926 silc_client_del_channel_private_keys,
4927 silc_client_del_channel_private_key,
4928 silc_client_list_channel_private_keys and
4929 silc_client_free_channel_private_keys
4931 Affected file lib/silcclient/client_channel.c.
4933 * Added the support for the private keys in the channel message
4934 sending and encryption and in the message reception and
4935 decryption. Affected funtions are
4936 silc_client_send_channel_message and silc_client_channel_message.
4938 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4940 * Added SKE's key verify callback to the client library's
4941 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4943 * Removed the statement that server (or router) must send USERS
4944 command reply when joining to the channel so that the client
4945 knows who are on the channel. Instead, the client list and
4946 client's mode list is now sent in the JOIN command reply to the
4947 client who joined channel. This is better solution.
4949 * Added function silc_server_get_users_on_channel and function
4950 silc_server_save_users_on_channel to the silcd/server.[ch].
4952 * Removed function silc_server_command_send_users from the
4955 * Do not show topic on the client library anymore. The topic is
4956 sent in the command reply notify to the application and the
4957 application must show the topic now.
4959 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4961 * Added client searching by nickname hash into the IDENTIFY and
4962 WHOIS commands in the server as they were clearly missing from
4963 them. Affected file is silcd/command.c.
4965 * Fixed a bug in private message receiving in the client library.
4966 The remote ID was freed and it wasn't supposed, now it is
4969 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4971 * Minor fix to the channel payload; allocate the data area, as it
4972 needs to be of specific length.
4974 * If the key agreement port is zero then the operating
4975 system will define the bound port. Affected files are
4976 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4978 * Added new function silc_channel_payload_decrypt into the file
4979 lib/silccore/silcchannel.[ch].
4981 * Moved the channel message etc, check from silc_packet_decrypt
4982 to applications. The library calls now a generic
4983 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4984 when the packet is either normal or special. This was done to
4985 allow more wide range of checking that was not allowed when
4986 the code was in library. Now applications can do virtually any
4987 checks to the packet and return to the library the decision how
4988 the packet should be processed. Affected files are
4989 lib/silccore/silcpacket.[ch].
4991 Added silc_server_packet_decrypt_check to the server and
4992 silc_client_packet_decrypt_check to the client library.
4994 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4995 to send with specified source and destination information.
4997 * Channel message delivery between routers was broken after the
4998 channel key distribution was fixed earlier. The channel key
4999 was used be to distributed to other routers as well which is not
5000 allowed by the protocol. Now this is fixed and channel keys
5001 really are cell specific and the channel message delivery between
5002 routers comply with the protocol specification.
5004 * Fixed various commands in server to check also the global list
5005 for the channel entry and not just the local list. The affected
5006 file silcd/command.c.
5008 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5010 * Added assert()s to buffer formatting and unformatting routines
5011 to assert (if --enable-debug) when error occurs. Affected
5012 file: lib/silcutil/silcbuffmt.c.
5014 * Changed to auto-reconnect to check whether the remote host is
5015 router and register the re-connect timeout if it is. It used
5016 to check that whether we are normal server, but router must do
5017 auto-reconnect with another router as well. Affected file
5020 * Removed the [<key len>] option from CMODE command as the cipher
5021 name decides the key length, nowadays. See the defined ciphers
5022 from the protocol specification.
5024 * Added [<hmac>] option to the CMODE command to define the HMAC
5025 for the channel. Added SILC_CMODE_HMAC channel mode.
5027 * Added [<hmac>] option for the JOIN command so that user can
5028 select which HMAC is used to compute the MACs of the channel
5031 * Added Hmac field to the Channel Message Payload. The integrity
5032 of plaintext channel messages are now protected by computing
5033 MAC of the message and attaching the MAC to the payload. The
5034 MAC is encrypted. Now, it is clear that this causes some
5035 overhead to the size of the packet but rationale for this is that
5036 now the receiver can verify whether the channel message decrypted
5037 correctly and also when private keys are set for the channel the
5038 receiver can decrypt the packet with several keys and check from
5039 the MAC which key decrypted the message correctly.
5041 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5042 lib/silccrypt/silccipher.[ch].
5044 * Added silc_hash_len to return the digest length into the
5045 lib/silcrypt/silchash.[ch].
5047 * Rewrote parts of Silc Channel Payload interface in the
5048 lib/silccore/silcchannel.[ch]. The encode function now also
5049 encrypts the packet and parse function decrypts it.
5051 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5053 * Fixed a minor formatting bug in the SKE's key material processing.
5054 It actually might have processed the keys wrong way resulting
5057 * Redefined the mandatory HMAC algorithms and added new algorithms.
5058 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5059 and hmac-md5 truncated to 96 bits. The mandatory is now
5060 hmac-sha1-96. Rest are optional (including the one that used
5061 to be mandatory). Rationale for this is that the truncated HMAC
5062 length is sufficient from security point of view and can actually
5063 make the attack against the HMAC harder. Also, the truncated
5064 HMAC causes less overhead to the packets. See the RFC2104 for
5067 * Added new [hmac] configuration section. The SKE used to use
5068 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5069 is of course wrong. The official names that must be proposed in
5070 the SKE are the ones defined in the protocol specification
5071 (hmac-sha1-96 for example). The user can configure any hmac
5072 using any hash function configured in the [hash] section. At
5073 least, the mandatory must be configured.
5075 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5077 * Added HMAC list to the SKE proposal list. It has now both
5078 hash algorithm list and HMAC list. This makes the protocol
5079 incompatible with previous versions. The SKE now seems to work
5080 the way it is supposed to work, for the first time actually.
5082 * Defined plain Hash algorithms to the protocol specification.
5085 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5087 * Implemented support for key agreement packets into the server.
5088 Added functions silc_server_key_agreement and
5089 silc_server_send_key_agreement. Other than these functions,
5090 server has nothing to do with this packet.
5092 * Added support for private message key packets into the server.
5093 Added functions silc_server_private_message_key and
5094 silc_server_send_private_message_key.
5098 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5099 called in the protocol's final callback instead in the END
5100 protocol state. This makes a little more sense and in the same
5101 time in client we can use the same protocol routines for normal
5102 key exchange and to key agreement packet handling as well.
5104 * Added to both client's and server's KE protocol context the
5105 SilcSKEKeyMaterial pointer to save the key material. We will
5106 bring the key material to the protocol's final callback by doing
5107 this. The final callback must free the key material.
5109 * Added SKE's packet_send callback into client's KE protocol
5110 context so that the caller can choose what packet sending function
5111 is used. This way we can use different packet sending when
5112 doing normal SKE when doing key agreement packet handling (in
5113 the key agreement packet handling we do not want to encrypt
5116 * Implemented the responder side of the key agreement routines
5117 in the client. The client can now bind to specified port and
5118 accept incoming key negotiation. The key material is passed
5119 to the application after the protocol is over.
5121 * Implemented the processing of incoming Key Agreement packet
5122 in the client. Added function silc_client_key_agreement to
5125 * Implemented the intiator side of the key agreement routines
5126 in the client. The client can now initiate key agreement with
5127 another remote client. The key material is passed to the
5128 application after the protocol is over.
5130 * Created client_keyagr.c to include all the key agreement
5133 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5134 SILC_TASK_CALLBACK except that it is not static.
5136 * Created client_notify.c and moved the Notify packet handling
5137 from the client.[ch] into that file.
5139 * Created client_prvmsg.c and moved all private message and
5140 private message key routines from the client.[ch] into that file.
5142 * Create client_channel.c and moved all channel message and
5143 channel private key routines from the client.[ch] into that file.
5145 * Changed silc_client_get_client_by_id_resolve to resolve with
5146 WHOIS command instead of IDENTIFY command, in the file
5147 lib/silclient/idlist.c.
5149 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5151 * Implemented the SKE's responder side to the Client library.
5153 * When FAILURE is received to the protocol do not trust it
5154 blindly. Register a timeout to wait whether the remote closes
5155 the connection as it should do it, only after that process the
5156 actual failure. This was changed to both client and server.
5158 * Added client_internal.h to include some of the structures
5159 there instead of client.h in lib/silcclient/.
5161 * Added function silc_task_unregister_by_callback to unregister
5162 timeouts by the callback function.
5164 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5166 * Some "Incomplete WHOIS info" errors has been appearing on the
5167 log files. Took away the entry->userinfo check from WHOIS
5168 reply sending. The entry->userinfo is now " " if client did not
5169 provide one. I thought this was fixed earlier but something
5170 is wrong still. Let's see if the error still appears.
5172 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5174 * Fixed a minor bug in the login when the channel key is
5175 re-generated in the server. It used to generate the key in
5176 wrong order and thus caused problems in the channel traffic.
5178 * Fixed a minor bug in channel key distsribution after
5179 KICK command. The key was not sent to the router even though
5182 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Added silc_ske_process_key_material_data as generic routine
5185 to process any key material as the SILC protocol dictates. The
5186 function is used by the actual SKE library but can be used by
5187 applications as well. This relates to the private message keys
5188 and the channel private keys since they must be processed the
5189 same way the normal SILC session keys. The protocol dictates
5190 this. Affected files: lib/silcske/silcske.[ch].
5192 Added also silc_ske_free_key_material to free the
5193 SilcSKEKeyMaterial structure.
5195 * Defined silc_cipher_set_key function to set the key for
5196 cipher without using the object's method function. The affected
5197 files: lib/silccrypt/silccipher.[ch].
5199 * Implemented silc silc_client_add_private_message_key,
5200 silc_client_add_private_message_key_ske,
5201 silc_client_del_private_message_key,
5202 silc_client_list_private_message_keys and
5203 silc_client_free_private_message_keys functions in the
5206 Added functions silc_client_send_private_message_key to send
5207 the Private Message Key payload and silc_client_private_message_key
5208 to handle incoming Private Message Key payload.
5210 * Added Cipher field to the Private Message Key payload to set
5211 the cipher to be used. If ignored, the default cipher defined
5212 in the SILC protocol (aes-256-cbc) is used.
5214 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5216 * Removed lib/silcclient/ops.h file.
5218 Redefined parts of the SILC Client Library API. Created new
5219 file silcapi.h that deprecates the ops.h file and defines the
5220 published Client Library API. Defined also private message key
5221 API and channel private key API into the file.
5223 This is the file that the application must include from the
5224 SILC Client Library. Other files need not be included by
5225 the application anymore.
5227 * Added new key_agreement client operation callback and also
5228 defined the Key Agreement library API for the application.
5230 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5232 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5233 is used by clients to request key negotiation between another
5234 client in the SILC network. If the negotiation is started it
5235 is performed using the SKE protocol. The result of the
5236 negotiation, the secret key material, can be used for example
5237 as private message key.
5239 Implemented the Key Agreement payload into the files
5240 lib/silccore/silauth.[ch].
5242 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5244 * Redefined ciphers for the SILC protocol. Added some new ciphers
5245 and defined the key lengths for the algorithms. Changed the
5246 code accordingly. The default key length is now 256 bits.
5248 * Fixed SKE key distribution function silc_ske_process_key_material
5249 when the key length is more than 128 bits. The default key
5250 length in SILC is now 256 bits.
5252 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5253 to indicate unsupported algorithm.
5255 * Renamed rijndael.c to aes.c and all functions as well.
5257 * Fixed a long standing channel key setting bug in client library.
5258 Weird that it has never surfaced before.
5260 * Fixed bug in channel deletion. If the entire channel is removed
5261 then it must also delete the references of the channel entry
5262 from the client's channel list as the client's channel entry and
5263 the channel's client entry share same memory.
5265 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5267 * Implemented CONNECT and SHUTDOWN commands in the client.
5269 * Implemented CLOSE command to the client.
5271 * Added the function silc_idlist_find_server_by_name into the
5272 files silcd/idlist.[ch].
5274 Added the function silc_idlist_find_server_by_conn into the
5275 files silcd/idlist.[ch].
5277 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5279 * DIE command was renamed to SHUTDOWN. Updated the both code
5282 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5283 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5285 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5288 * Added function silc_server_create_connection function to create
5289 connection to remote router. My server implementation actually
5290 does not allow router to connect to normal server (it expects
5291 that normal server always initiates the connection to the router)
5292 so the CONNECT command is only good for connecting to another
5295 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5297 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5298 or some other client was kicked from the channel.
5300 Implemented the handling of the notify type to both client
5303 Implemented silc_server_send_notify_kicked to send the KICKED
5304 notify. It is used to send it to the server's primary router.
5306 * Implemented the KICK command into server and client.
5308 * Added `query' argument to the silc_idlist_get_client function
5309 to indicate whether to query the client from server or not if
5312 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5313 to indicate that the client is not channel founder.
5317 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * Removed the rng context from SilcPacketContext structure and
5320 changed that the packet routine uses the Global RNG API.
5322 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5324 * Added support for quit message that client can "leave" on the
5325 channel when it quits the SILC. It is ditributed inside the
5326 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5328 Added silc_server_free_client_data that will take the
5329 signoff message as argument.
5331 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5333 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5335 * Updated parts of the protocol specification to keep it up
5338 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5340 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5341 payloads in one packet.
5343 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5344 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5345 use now the new List flag.
5347 * Also deprecated the following packet types: REPLACE_ID,
5348 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5350 * Added list support for Notify packet in server.
5352 * Added silc_server_send_notify_channel_change to send the
5353 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5354 the silc_server_send_replace_id.
5356 * Added silc_server_send_notify_nick_change to send the
5357 NICK_CHANGE notify type. Deprecates the function
5358 silc_server_send_replace_id.
5360 * Added silc_server_send_notify_join to send the JOIN notify type.
5361 Deprecates the function silc_server_send_new_channel_user.
5363 * Added silc_server_send_notify_leave to send LEAVE notify type.
5364 Deprecates the function silc_server_send_remove_channel_user.
5366 * Added silc_server_send_notify_cmode and
5367 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5368 types. Deprecates the silc_server_send_set_mode function.
5370 * Added SERVER_SIGNOFF notify type to indicate that server has
5371 quit. This means that all clients on the channel from that
5372 server will drop. This can be also used when netsplit happens.
5374 Deprecated REMOVE_ID packet type since it is not needed anymore
5377 Added silc_server_send_notify_server_signoff to send the
5378 SERVER_SIGNOFF notify type. Deprecates the function
5379 silc_server_send_remove_id.
5381 Added also silc_server_send_notify_signoff to send the
5382 SIGNOFF notify type.
5384 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5385 SILC protocol from this day on. Changed the protocol
5386 specification as well.
5388 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5389 notify type. It is used between routers to notify about
5390 topic changes on a channel.
5392 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5395 * Partly updated the protocol specification to comply with the
5396 changes now made. It is still though a bit outdated.
5398 * The JOIN notify type now takes one extra argument <Channel ID>.
5399 The packet used to be destined to the channel but now the
5400 JOIN type may be sent as list thus it is impossible to
5401 destine it to any specific channel. By adding this argument
5402 it is again possible.
5404 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Added CREDITS file. The CHANGES and CREDITS file will appear
5407 in the distribution as well.
5409 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5411 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5412 types in the server's silcd/packet_receive.c.
5414 * Implemented CMODE and CUMODE to work in router environment.
5416 * Fixed minor encoding and decoding buglet from the
5417 lib/silccore/silcmode.c.
5419 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5422 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5424 * Changed all SilcConfigServer* and silc_config_server* to
5425 SilcServerConfig* and silc_server_config*, respectively.
5428 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5430 * Associated the ID (client or server ID) to the Authentication
5431 Payload to avoid any possibility of forging. Updated the
5432 protocol specification and the code accordingly.
5434 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5436 * The RSA key length is now save to the RsaKey context in the
5437 key generation process in lib/silccrypt/rsa.c. The key length
5438 is now used to figure out the maximum size of the block allowed
5439 to be encrypted/signed.
5441 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5442 is equivalent to the silc_mp_mp2bin but does not allocate any
5445 * Changed silc_mp_mp2bin API to take length argument. If it is
5446 non-zero then the buffer is allocated that large. If zero, then
5447 the size is approximated using silc_mp_sizeinbase, which however
5450 * Created Global RNG API which is global RNG that application can
5451 initialize. After initializing, any routine anywhere in the
5452 code (including library) can use RNG without allocating a new
5453 RNG object. This was done to allow this sort of use of the
5454 RNG in code that has no chance to allocate RNG object. All
5455 applications currently allocate this and many routines in the
5456 library use this. Affected file lib/silccrypt/silcrng.[ch].
5458 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5459 it to use the Global RNG API.
5461 * Defined Authentication Payload into protocol specification that
5462 is used during SILC session to authenticate entities. It is
5463 used for example by client to authenticate itself to the server
5464 to obtain server operator privileges.
5466 Implemented this payload into the lib/silccore/silcauth.[ch].
5467 Implemented also routines for public key based authentication
5468 as the new protocol specification dictates.
5470 Moved definitions of different authentication methods from
5471 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5473 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5474 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5475 silc_pkcs_verify_with_hash functions into the file
5476 lib/silccrypt/silcpkcs.[ch].
5478 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5480 * The client entry's userinfo pointer must be always valid.
5481 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5482 will fail since it requires the userinfo. Now, the userinfo
5483 is allocated as "" if actual userinfo does not exist. Actually,
5484 it must exist and it is totally Ok to drop client connections
5485 that does not announce the userinfo. However, we will make
5486 this workaround for now.
5488 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5489 to return the remote port by socket.
5491 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5493 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5494 SILC_SERVER_PENDING_EXEC and added an new macro
5495 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5496 data or when error occurs while processing the pending command.
5498 Added new argument `destructor' into silc_server_command_pending
5499 and to the SilcServerCommandPending object. This destructor is
5500 now called after calling the pending callback or if error occurs
5501 immediately. If error occurs the actual pending callback won't
5502 be called at all - only the destructor. The destructor may be
5503 NULL if destructor is not needed.
5505 All this applies for client library code as well. Similar
5506 changes were made there as well for the pending commands.
5508 In the client, the application must now allocate the
5509 SilcClientCommandContext with the silc_client_command_alloc
5512 * Added reference counter to the SilcServerCommandContext. Added
5513 function silc_server_command_alloc and silc_server_command_dup
5516 Same type of functions added to the client library for the same
5519 * Removed the cmd_ident from IDListData away since it is now
5520 global for all connections. It is the command identifier used
5521 in command sending and with pending commands. The affected file
5524 * Added reference counter to the SilcSocketConnection objecet to
5525 indicate the usage count of the object. The object won't be
5526 freed untill the reference counter hits zero. Currently only
5527 server uses this, and client ignores it. The client must be
5528 set to use this too later. The affected files are
5529 lib/silccore/silcsockconn.[ch]. Added also the function
5530 silc_socket_dup to increase the reference counter.
5532 This was mainly added because it is possible that the socket
5533 is removed underneath of pending command or other async
5534 operation. Now it won't be free'd and proper DISCONNECTING
5535 flags, etc. can be set to avoid sending data to connection that
5536 is not valid anymore.
5538 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5539 the connection. After that it sets SILC_SET_DISCONNECTED.
5540 It is, however, possible that the socket data is not still freed.
5541 The silc_server_packet_process now checks that data is not
5542 read or written to connection that is DISCONNECTED. The socket
5543 get's freed when the reference counter hits zero.
5545 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5547 * Changed the client operation API: channel_message operation's
5548 `sender' is now the client entry of the sender, not the nickname
5549 and the `channel' is the channel entry, not the channel name.
5551 In the private_message operation the `sender' is now also the
5552 client entry of the sender not the nickname.
5554 Affected file is lib/silcclient/ops.h and all applications
5555 using the client operations.
5557 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5559 * Moved the calling of ops->connect() from connect_to_server_final
5560 into receive_new_id functin since that is the point when the
5561 client is actually allowed to send traffic to network. The
5562 affected file is lib/silcclient/client.c.
5564 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5567 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5568 (if needs broadcasting) instead of broadcasting the packets one
5569 by one which would make a burst in the network traffic.
5571 * Added `broadcast' argument to the functions in silcd/server.[ch]
5572 silc_server_create_new_channel[_with_id] to indicate whether
5573 to send New Channel packet to primary router.
5575 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5577 * Added new function into the silcd/server.[ch] files:
5578 silc_server_create_new_channel_with_id to create new channel with
5579 already existing Channel ID.
5581 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5582 lib/silccore/silcpacket.h. This packet is used t send list of
5583 Set Mode payloads inside one packet. Server uses this to set
5584 the modes for the channels and clients on those channels, that it
5585 announced to the router when it connected to it. The protocol
5586 specification has been updated accordingly.
5588 * The silc_server_new_channel did not handle the packet coming
5589 from normal server as it normally does not send that. However,
5590 when it announces its channels it does send it. Implemented
5591 the support for that.
5593 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5594 into the file lib/silccore/id.h.
5596 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Fixed memory leaks in the functions silc_idlist_del_client,
5599 silc_idlist_del_channel and silc_idlist_del_server in the file
5600 silcd/idlist.c. All of those leaked like a sieve.
5602 * Fixed some small memory leaks in the client's function
5603 silc_client_notify_by_server.
5605 * Added functions into silcd/server.c: silc_server_announce_clients,
5606 silc_server_announce_channels and silc_server_announce_server.
5607 These functions are used by normal and router server to announce
5608 to its primary router about clients, channels and servers (when
5609 router) that we own. This is done after we've connected to the
5612 These functions effectively implements the following packet types:
5613 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5614 and SILC_PACKET_NEW_ID_LIST.
5616 * Added new functions into the silcd/packet_receive.[ch]:
5617 silc_server_new_id_list, silc_server_new_channel_list and
5618 silc_server_new_channel_user_list to handle the incoming
5619 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5621 * Added support of changing Channel ID in the function
5622 silc_server_replace_id. If the server that announces a channel
5623 to the router already exists in the router (with same name but
5624 with different Channel ID), router is responsible to send
5625 Replace ID packet to the server and force the server to change
5626 the Channel ID to the one router has.
5628 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5629 client that the Channel ID has been changed by the router. The
5630 normal server sends this to the client. Client must start using
5631 the new Channel ID as the channel's ID.
5633 Implemented handling of this new type into lib/silcclient/client.c
5634 into the function silc_client_notify_by_server.
5636 * Added new function silc_idlist_replace_channel_id into the files
5637 silcd/idlist.[ch] to replace the Channel ID.
5639 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5641 * Call silc_server_command_identify_check always when processing
5642 the IDENTIFY command in silcd/command.c
5644 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5646 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5647 send keepalive packets. The packet can be sent by clients,
5648 servers and routers.
5650 Added function silc_socket_set_heartbeat into the file
5651 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5652 If not set, the heartbeat is not performed. The actual
5653 heartbeat is implemented in the low level socket connection
5654 library. However, application is responsible of actually
5657 Added silc_server_send_heartbeat to send the actual heartbeat
5658 packet into silcd/packet_send.[ch]. Server now performs
5659 keepalive with all connections.
5661 * Added silc_task_get_first function into lib/silcutil/silctask.c
5662 to return the timeout task with shortest timeout. There was a bug
5663 in task unregistration that caused problems. TODO has been
5664 updated to include that task system must be rewritten.
5666 * The client library will now resolve the client information when
5667 receiving JOIN notify from server for client that we know but
5668 have incomplete information.
5670 * Rewrote parts of silc_server_remove_from_channels and
5671 silc_server_remove_from_one_channel as they did not remove the
5672 channel in some circumstances even though they should've.
5674 * Encryption problem encountered in server:
5676 The LEAVE command used to send the Channel Key packet to the
5677 router immediately after generating it. However, the code
5678 had earlier sent Remove Channel user packet but not immediately,
5679 ie. it was put to queue. The order of packets in the router
5680 was that Channel Key packet was first and Remove Channel User
5681 packet was second, even though they were encrypted in the
5682 reverse order. For this reason, MAC check failed. Now, this
5683 is fixed by not sending the Channel Key packet immediately but
5684 putting it to queue. However, this is more fundamental problem:
5685 packets that are in queue should actually not be encrypted
5686 because packets that are sent immediately gets encrypted
5687 actually with wrong IV (and thus MAC check fails). So, packets
5688 that are in queue should be encrypted when they are sent to
5689 the wire and not when they put to the queue.
5691 However, the problem is that the current system has not been
5692 designed to work that way. Instead, the packet is encrypted
5693 as soon as possible and left to the queue. The queue is then
5694 just purged into wire. There won't be any fixes for this
5695 any time soon. So, the current semantic for packet sending
5698 o If you send packet to remote host and do not force the send
5699 (the packet will be in queue) then all subsequent packets to the
5700 same remote host must also be put to the queue. Only after the
5701 queue has been purged is it safe again to force the packet
5704 o If you send all packets immediately then it safe to send
5705 any of subsequent packets through the queue, however, after
5706 the first packet is put to queue then any subsequent packets
5707 must also be put to the queue.
5709 Follow these rules and everything works fine.
5711 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5713 * Added new function silc_server_remove_clients_by_server to
5714 remove all client entries from ID list when the server connection
5715 is lost. In this case it is also important to invalidate all
5716 client entires as they hold the invalid server entry. This
5717 fixes fatal bug when server has lost connection and will reconnect
5720 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5722 * Made some sanity checks to silc_server_daemonise like to check
5723 whether the requested user and group actually exists.
5725 * Added sanity check to SKE's silc_ske_responder_finish to check
5726 that the public and private key actually is valid.
5728 * Invalidate the client's nickname when receiving Replace ID
5729 packet and the Client ID is being replaced. This means that the
5730 server will query the nickname if someone needs it (client)
5733 * Sort the ID Cache in client library when the ID Cache data
5734 has changed (needs sorting).
5736 * Do not allow for SILC client to create several connections to
5737 several servers. The client does not support windows right now
5738 and generating multiple connections causes weird behaviour.
5740 Irssi-silc client does support windows and can handle several
5741 connections without problems, see: www.irssi.org and SILC plugin.
5743 * Fixed some places where client was added to the IDList. The
5744 rule of thumb is following (in order to get everything right):
5745 If the client is directly connected local client then the
5746 `connection' argument must be set and `router' argument must be
5747 NULL to silc_idlist_add_client function. If the client is not
5748 directly connected client then the `router' argument must
5749 bet set and the `connection' argument must be NULL to the
5750 silc_idlist_add_client function.
5752 * The funtion silc_server_packet_send_local_channel actually did
5753 not check whether the client was locally connected or not. It
5754 does that now. Fixed a bug related to LEAVE command.
5756 * Fixed Remove Channel User payload parsing bug in server's
5757 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5759 * The server's silc_server_save_channel_key now checks also the
5760 global ID list for the channel as it might not be in the local
5761 list. Fixed a bug related to LEAVE command.
5763 * Is this the end of the [<unknown>] buglet that has been lurking
5764 around for a long time? A little for loop fix in server's
5765 silc_server_command_whois_parse that is used by both IDENTIFY
5766 and WHOIS command. At least, this was a clear bug and a cause
5767 of one type of [<unknown>] buglet.
5769 * WHOIS and IDENTIFY commands call the function
5770 silc_server_command_[whois/identify]_check function even if
5771 we are not router server.
5773 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5775 * Added --with-gmp configuration option. If set the GMP
5776 is always compiled in the SILC source tree. If not set then
5777 it is checked whether the system has the GMP3 installed. If
5778 it has then the GMP won't be compiled (the system's headers
5779 and library is used), if it doesn't have it then the GMP is
5780 compiled in the SILC source tree.
5782 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5784 * Changed RSA private exponent generation to what PKCS #1
5785 suggests. We try to find the smallest possible d by doing
5786 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5787 not security fix but optimization.
5789 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5791 * Added new config entry [Identity] to fork the server and run
5792 it as specific user and group. A patch from Bostik.
5794 * Imported Dotconf configuration library into lib/dotconf.
5795 This will be used to create the SILC configuration files later.
5796 It will appear in the distsribution after this commit.
5798 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5800 * A big code auditing weekend happening. Auditing code for
5801 obvious mistakes, bugs and errors. Also, removing any code
5804 Removed files for being obsolete:
5806 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5807 inline in the file lib/silcutil/silcbuffer.h)
5809 o lib/silcutil/silcbufutil.c (the header has inline versions)
5811 Changed code to fix possible error conditions:
5813 o The buffer formatting routines now check that the destination
5814 buffer really has enough space to add the data. This applies for
5815 both buffer formatting and unformatting
5816 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5817 unformatting was changed to accomodate following rules:
5818 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5819 sent to the function while XXX_*STRING will not allocate or copy
5820 the data into the buffer. Instead it sets the pointer from the
5821 buffer into the pointer sent as argument (XXX_*STRING used to
5822 require that the pointer must be allocated already). This change
5823 makes this whole thing a bit more consistent and more optimized
5824 (note that the data returned in the unformatting with XXX_*STRING
5825 must not be freed now). The routines return now -1 on error.
5827 o Tried to find all code that use buffer_format and buffer_unformat
5828 and added return value checking to prevent formatting and
5829 especially unformatting errors and possible subsequent fatal
5832 o Changed ske->x and ske->KEY to mallocated pointers in
5833 lib/silcske/silcske.h. Fixed possible data and memory leak.
5835 o Added return value checking to all *_parse* functions. Fixed
5836 many memory leaks as well.
5838 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5839 so that buffer overflows would not happen. All code now also
5840 checks the return value as it can fail.
5842 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5844 * Added reconnection support to server if the normal server looses
5845 its connection to the router (for example if router is rebooted).
5846 The server performs normal reconnection strategy implemented
5847 to the server. Affected file silcd/server.c.
5849 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5851 * Added new packet type SILC_PACKET_SET_MODE that is used to
5852 distribute the information about changed modes (for clients,
5853 channels and clients channel modes) to all routers in the
5854 network. Updated the protocol specification accordingly.
5856 Added functions into silcd/packet_send.c and
5857 silcd/packet_receive.c: silc_server_send_set_mode,
5858 silc_server_set_mode.
5860 Added new files silcmode.[ch] into lib/silccore that implements
5861 the encoding and decoding of Set Mode Payload. Added new type
5862 SilcSetModePayload. Moved the definitions of different modes
5863 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5865 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5867 * Oops, a little mistake in server's connection authentication
5868 protocol. The protocol is not ended with FAILURE but with
5869 SUCCESS if the authentication is Ok. :) Affected file is
5872 * Implemented NICK_CHANGE notify handling in server in the file
5873 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5874 the local clients on the channel. After the changing nickname
5875 in router environment snhould work and the [<unknown>] nickname
5876 should appear no more.
5878 The silc_server_replace_id function that receives the Replace ID
5879 payload now sends the NICK_CHANGE notify type also in the file
5880 silcd/packet_receive.c
5882 * Changed WHOIS and IDENTIFY command to support the maximum amount
5883 of arguments defined in protocol specs (3328 arguments). This
5884 fixed a bug that caused problems when there were more than three
5887 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5889 * Added extra parameter, command identifier, to the
5890 silc_client_send_command so that explicit command identifier
5893 Changed that ID list routines uses specific command identifier
5894 when sending WHOIS/IDENTIFY requests to the server so that they
5895 can be identified when the reply comes back.
5897 Affected files lib/silcclient/command.[ch],
5898 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5900 * Added `sender' argument to silc_server_packet_send_to_channel
5901 to indicaet the sender who originally sent the packet to us
5902 that we are now re-sending. Ignored if NULL. Affected file
5903 silcd/packet_send.[ch].
5905 * Added some server statistics support in silcd/server_internal.h
5906 SilcServerStatistics structure and around the server code. Also
5907 send some nice statistics information when client is connecting
5910 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5912 * Fixed channel ID decoding in server's JOIN command reply in
5913 silcd/command_reply.c
5915 * Fixed braodcasting of replace ID payload to not to send it if
5916 we are standalone server in silcd/packet_receive.c.
5918 * Fixed all channel message sending routines to not to send
5919 packets to clients that has router set, since they are routed
5920 separately in the same function earlier. Affects file
5921 silcd/packet_send.c and all channel packet sending functions.
5923 * In USERS reply, res_argv[i] are not allocated, the table
5924 is allocated. Thus changed that free the table, not its
5927 * In server's whois_check and identify_check if the client is
5928 locally connected do not send any WHOIS commands - they are not
5931 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5933 * Fixed some minor bugs in client when sending WHOIS command. The
5934 arguments was in wrong order.
5936 * Removed statis function add_to_channel from server in
5937 silcd/command.c that was previously used with the joining but
5940 * Tested USERS command in router environment successfully with two
5941 routers, two servers and two clients.
5943 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5945 * Reorganized the USERS command and command reply in client library
5946 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5947 When the command is given by user we register a pending command
5948 callback that will reprocess the command after the reply has been
5949 received from the server. When reprocessing the packet we then
5950 display the information. Thus, the USERS information is displayed
5951 now in the command callback instead of in the command reply
5952 callback. The processing of the command is same as previously
5953 when server has sent the command reply in the JOINing process.
5955 * Added to USERS command in silcd/command_reply.c to join the client,
5956 we didn't use to know about, to the channel after we've created
5957 a client entry for it. Also, for clienet we did know already still
5958 check whether it is on the channel or not and add it if not.
5960 * Removed silc_server_command_join_notify as the function and its
5963 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5965 * Changed the client's pending command handling to the same as the
5966 server's pending command handling. It is also now possible to
5967 execute command reply functions from other command reply
5968 function as the function callbacks for commands and command
5969 replies are one and same. The pending commands are not static
5970 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5971 in client connection context. Thus, pending commands are server
5972 connection specific as it is convenient.
5974 Changed the function silc_client_command_pending and
5975 silc_client_command_pending_del and added new function
5976 silc_client_command_pending_check. Removed the
5977 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5980 * Added cmd_ident, current command identifier, to the client
5981 connection context in lib/silcclient/client.h to keep track on
5982 command identifiers used in command sending. Client's command reply
5983 function handling now supports the mandatory command identifiers.
5985 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5986 funtions in client to fully support pending command callbacks.
5988 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5989 as one of the arguments to the application in the command reply
5992 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5993 before first releasing SILC but came back. Now it is removed again
5994 and should come back nomore. The FORWARDED flag was used only
5995 by the JOINing procedure by forwarding the command packet to router.
5996 Now, the JOINing procedure has been changed to more generic (due
5997 to various router environment issues) and FORWARDED is not needed
5998 anymore for anything. The protocol specification is yet to be
6001 Now, removed silc_server_packet_forward from server and the flag
6002 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6004 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6006 * Renamed NAMES command to USERS command. The NAMES was named that
6007 due to historical reasons. Now it is renamed. Also, rewrote
6008 parts of the USERS command. The nickname list is not sent anymore
6009 by the server. Only Client ID and mode lists are sent in the USERS
6010 command. Changed this also to the protocol specification.
6012 The client now resolves the names and stuff after it receives
6013 the USERS list from the server when joining to the channel.
6015 * WHOIS and IDENTIFY commands has been changed to support multiple
6016 Client ID's per command. One can now search for multiple users
6017 in the network by sending only one WHOIS or IDENTIFY command.
6018 Changed the code and the protocol specifications.
6020 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6021 uses silc_server_command_whois_parse to parse the request. */
6023 * If normal server, do not parse the WHOIS and IDENTIFY requests
6024 before sending it to the router. Saves some time.
6026 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6028 * Fixed JOIN command on client library. Wrong number of arguments
6029 used to crash the client.
6031 * Added silc_server_channel_has_global function to check whether
6032 channel has global users or not.
6034 * Added silc_server_channel_has_local function to check whether channel
6035 has locally connected clients on the channel.
6037 * The silc_server_remove_from_one_channel now checks whether the
6038 channel has global users or not after given client was removed from
6039 the channel. It also checks whether the channel has local clients
6040 on the channel anymore. If it does not have then the channel entry
6041 is removed as it is not needed anymore.
6043 * The silc_server_notify now checks on JOIN notify whether the joining
6044 client is one of locally connected or global. If it is global then
6045 the channel has now global users on the channel and that is marked
6046 to the channel entry. Also, it now saves the global client to
6047 global list who is joining and JOINs it to the channel. This is
6048 for normal server, that is.
6050 Changed silc_server_send_notify_on_channel,
6051 silc_server_packet_relay_to_channel and
6052 silc_server_packet_send_to_channel check if we are normal server
6053 and client has router set (ie. global client) do not send the
6054 message to that client, as it is already routed to our router.
6056 * Implemented LEAVE notify type handling in silc_server_notify
6059 * Tested LEAVE command in router environment successfully. Tested
6060 with two routers, two servers and two clients.
6064 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6066 * Implemented SIGNOFF notify type handling in silc_server_notify
6069 * silc_server_remove_id now removes the client entry from all channels
6070 it has joined and thusly sends SIGNOFF notify type.
6072 * Rewrote the NAMES list generation in server by removing two excess
6073 loops. The lists are created now inside one loop.
6075 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6077 * silc_server_remove_channel_user checks now also global list
6078 for channel and client.
6080 * silc_server_new_channel_user checks now both local and global
6081 list for channel and client. Fixed a bug in client id decoding.
6082 Used to decode wrong buffer.
6084 * silc_server_channel_message checks now both local and global
6085 list for channel entry.
6087 * Tested channel joining (hence JOIN) in router environment
6088 successfully. Tested with two routers, two servers and two
6091 * Tested channel message sending in router environment successfully.
6093 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6095 * Added silc_server_save_channel_key into server.[ch] to save the
6096 received channel key in Channel Key payload processing. It is
6097 also used in JOIN command reply handling.
6099 Equivalent function silc_client_save_channel_key added into
6100 client.[ch] into client library.
6102 * Changed JOIN command reply to send information whether the channel
6103 was created or not (is existing already) and the channel key
6104 payload. Changed protocol specs accordingly.
6106 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6107 the request was sent by ID and not by nickname. Crashed on
6110 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6112 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6113 now correctly save the received data.
6115 * silc_server_free_sock_user_data now notifies routers in the
6116 network about entities leaving the network.
6118 At the same time implemented functions silc_server_remove_id
6119 and silc_server_send_remove_id to receive and send REMOVE_ID
6120 packets. The packet is used to notify routers in the network
6121 about leaving entities. The ID removed will become invalid in
6124 * Added function silc_idlist_del_server into server. Removes and
6125 free's server entry from ID list.
6127 * silc_server_private_message function now checks, if we are router,
6128 that the destination ID really is valid ID, naturally.
6130 * In router when NEW_ID packet is received (for new client) the
6131 hash of the Client ID is saved in the ID Cache but the
6132 client->nickname is set to NULL, instead of putting the hash
6135 IDENTIFY command now also checks that client->nickname must be
6136 valid. If it is not if will request the data from the server who
6137 owns the client. Added new function
6138 silc_server_command_identify_check.
6140 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6141 to set the command to already allocated Command Payload.
6143 * Tested private message sending in router environment with two
6144 routers, two servers and two clients. Fixed minor bugs and now
6147 * Fixed segfault from client's NAMES command. Used to crash if
6150 * Forwarded packets must not be routed even if it is not destined
6151 to the receiver. Changed server code comply with this.
6153 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6155 * Added `require_reverse_mapping' boolean value to ServerParams
6156 structure. If TRUE (not default) the server will require that
6157 the connecting host has fully qualified domain name.
6159 If the reverse mapping is not required and hostname could not be
6160 found the IP address is used as hostname.
6162 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6164 * Implemented version string checking to both client and server.
6165 The check is incomplete currently due to the abnormal version
6166 strings used in development version of SILC.
6168 * Changed all command functions in server to use the new
6171 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6173 * Changed char *data to unsigned char *data in ID Cache system to
6174 support binary data as ID Cache data. Changed code to support
6175 binary data in lib/silccore/idcache.c.
6177 * Renamed silc_server_packet_relay_command_reply to
6178 silc_server_command_reply as it is normal packet receiving
6179 function. Rewrote the function to accept command replys for
6180 servers and not only for clients.
6182 * Mark remote router always as registered server if we are connecting
6183 to it. Otherwise, commands sent by the router to us are ignored.
6185 * All ID List find routines now returns the ID Cache Entry pointer
6186 as well if requested.
6188 * WHOIS command works now in router environment, tested with two
6189 routers, two servers and two clients.
6191 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6192 in router environment (as it is almost equivalent to WHOIS) but
6193 hasn't been tested thoroughly. Added new functions:
6195 silc_server_command_identify_parse
6196 silc_server_command_identify_send_reply
6197 silc_server_command_identify_from_client
6198 silc_server_command_identify_from_server
6200 * Disabled route cache adding because adding two different ID's with
6201 same IP replaces the old cache entry thus giving wrong route.
6202 The entry->router->connection is always the fastest route anyway
6203 so route cache may not be needed. Of course, new routes maybe
6204 established after receiving the ID when the entry->router->connection
6205 might not be anymore the most optimal.
6207 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6209 * Add route cache for received ID for fast routing.
6211 * Added silc_server_packet_route to route received packet on router
6212 that is not destined to us.
6214 * Renamed silc_server_get_route to silc_server_route_get.
6216 * Added id_string and id_string_len fields into SilcServer to
6217 include encoded ServerID for fast comparing without excess
6218 encoding of the ID's.
6220 * Cleaned up WHOIS command on server side. Added following static
6223 silc_server_command_whois_parse
6224 silc_server_command_whois_check
6225 silc_server_command_whois_send_reply
6226 silc_server_command_whois_from_client
6227 silc_server_command_whois_from_server
6229 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6230 arguments in command replies. All command functions should be
6231 updated to use this macro.
6233 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6235 * Minor typo fixes on command reply handling on server.
6237 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6239 * Added silc_server_command_add_to_channel internal routine to add
6240 the client to the channel after router has created the channel and
6241 sent command reply to the server.
6243 * Added generic silc_server_send_command to send any command from
6246 * Use static buffer with ID rendering instead of duplicating data.
6248 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6250 * Fixed a channel user mode bug when joining to a channel server gave
6251 everybody channel founder rights, oops.
6253 * We mark ourselves as the router of the incoming server connection
6254 if we are router ourselves. This way we can check in some packet
6255 sending functions whether it is locally connected server. For
6256 incoming router connections we put NULL.
6258 * For router sending packets locally means now always sending the
6259 packet cell wide; to local clients and local servers. For normal
6260 server sending packet locally means sending it to only local
6263 * Fixed the JOIN command to really work in router environment. If the
6264 channel is created it is always created by the router. Router is
6265 also responsible of making the initial joining to the channel,
6266 sending JOIN notify to the sending server and distributing
6267 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6268 does not exist server doesn't do anything else but forward the
6269 command to the router which performs everything.
6271 * Added silc_server_send_channel_key function to send the Channel Key
6274 * Added silc_server_create_channel_key to create new channel key. The
6275 channel key is now re-generated everytime someone joins or leaves
6276 a channel, as protocol dictates. Note: channel->key_len is the
6279 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6281 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6282 packet_receive.[ch] to separate packet sending and receiving
6283 routines. The server.[ch] now includes everything else including
6284 actual packet processing (writing and reading data) and other
6287 Renamed silc_server_private_message_send_internal to
6288 silc_server_send_private_message. The routine is still though
6289 used only to relay private messages as server does not send
6290 private messages itself.
6292 Renamed silc_server_new_channel to silc_server_create_new_channel
6293 and added new function sicl_server_new_channel that handles the
6294 incoming New Channel packet. Added also new sending function
6295 silc_server_send_new_channel to send New Channel Payload.
6297 * Added new function silc_server_notify to process incoming notify
6298 packet to the server/router. Server may then relay the notify
6299 to clients if needed.
6301 * Added new function silc_server_new_channel_user to process incoming
6302 New Channel User packet. Router will redistribute the packet and
6303 send JOIN notify to its local clients and locally connected servers
6304 if needed. Normal server will send JOIN notify to its local client
6305 on same channel when received this packet. Added also corresponding
6306 sending function silc_server_send_new_channel_user to sent the
6309 * Added boolean route argument to send_notif_to_channel and
6310 packet_send_to_channel functions to attempt to route the packet
6311 if it is TRUE and send only locally if it is FALSE.
6313 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6315 * silc_server_replace_id now broadcasts the received replace ID
6316 packet if it is not broadcast packet already. The router must
6317 broadcast to inform other routers about changed ID.
6319 * Added backpointer to server's router into SilcServer context in
6320 silcd/server_internal.h.
6322 * Fixed silc_server_packet_broadcast to send correct broadcast
6325 * The channel key is now distributed to the local client as soon
6326 as it is received from the router (in router environment) so that
6327 no other packet may be sent for the channel until client has
6330 * silc_server_remove_channel_user now broadcasts the received
6331 Remove Channel User packet if it is not broadcast packet already.
6332 The router must broadcast to inform other routers about removed
6335 * Added users field into SilcPacketContext that is a reference count
6336 of the context. One can increase the reference count by calling
6337 silc_packet_context_dup which is now changed to just increase the
6338 reference count instead of duplicating the data. The reference
6339 count is decresed by calling silc_packet_context_free that will
6340 free the data after the reference count hits zero.
6342 For now on the packet context and everything allocated into it
6343 (including the raw packet from network) must be freed by calling
6344 the new silc_packet_context_free function. Added also new function
6345 silc_packet_context_alloc that must be used now to allocate the
6346 context. This also means that if a routine is asynchronous from
6347 silc_[client/server]_packet_parse_type the packet context must
6348 be duplicated by calling silc_packet_context_dup. Otherwise it
6349 gets free'd after silc_[client/server]_packet_parse_type returns.
6350 Also, one must remember that if packet is duplicated then its
6351 reference count must be decresed by calling the free function as
6352 many times as it was duplicated.
6354 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6355 from both client and server.
6357 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6359 * Made joining to a channel working in router environment.
6361 * Cleaned up JOIN command on server side and create function
6362 silc_server_command_join_channel internal routine to make the
6365 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6367 * Changed silc_command_pending list to SilcDList. Also, added
6368 `ident' field to SilcServerCommandPending structure to identify
6369 the reply and to call correct callback.
6371 Added silc_server_command_pending_check function to replace the
6372 corresnponding macro. The silc_command_pending list is not
6375 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6376 to set identifier to previously allocated Command Payload. It
6377 is used to set identifier for command when resending Command
6380 * Added silc_command_payload_encode_payload to encode Command
6381 Payload buffer from SilcCommandPayload structure.
6383 * Added silc_argument_payload_encode_payload to encode Argument
6384 payload buffer from SilcArgumentPayload structure.
6386 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6388 * Changed WHOIS command to support router connection on server side.
6389 The whois request is always sent to router unless the server is
6390 standalone server. After server has received the reply from the
6391 router will it send the reply to the client.
6393 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6394 broadcast received broadcast packet. The function is used only
6395 by router. The broadcast packet is always sent to the router's
6398 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6399 render given ID to printable string, for log files for example.
6401 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Made basic router to router connections working. At least they
6404 can now connect to each other but nothing really works the way
6405 they are supposed - yet.
6407 * Added new initiator token to RouterConnection configuration
6408 file in silcd/serverconfig.[ch]. It is used to tell whether we
6409 are the initiator to the remote router or whether we'll expect
6410 the other end to connect.
6412 * Moved registering of listener task to silc_server_init, hence
6413 the server starts listenning as soon as it is run, even if it
6414 does not have connections to other routers. Let's see how well
6417 * Changed default connection retry timeouts for more suitable in
6420 * Removed cipher and such arguments from silc_idlist_add_client
6421 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6422 Added new function silc_idlist_add_data to add the keys and stuff
6425 * Added SilcIDListData structure and added it to SilcClientEntry
6426 and SilcServerEntry as their first field in the structure. This
6427 way we can explicitly cast the ID entries to the SilcIDListData
6428 structure and get common data for the entries. In past, we had
6429 to first check what type of connection it is and then cast it to
6430 correct ID entry type. Now, we can directly cast the opaque
6431 pointer to the SilcIDListData (no matter what ID entry it actually
6432 is) and get the data needed.
6434 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6436 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6437 in some circumstances even if threre were timeout tasks, though not
6438 IO tasks, but tasks anyway. Now fixed.
6440 * Defined SilcServerConnection structure to hold connection specific
6441 stuff about directly connected servers and routers. The definition
6442 is currently in silcd/server_internal.h. I thought about having
6443 a bit more important role fro this struct but for now it is used
6444 only when connecting to other server (or router actually).
6446 * Added connecting retry support in server when connecting to
6447 router(s). The retry feature implement exponential backoff
6448 algorithm. Also, added SilcServerParams structure to hold default
6449 parameters for server. For now, it include these retry settings
6450 and are hard coded. After server is moded to be as Silc Server
6451 Library this structure will be more important.
6453 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6455 * Changed client librarys channel->clients table to SilcList and
6456 changed code accordingly.
6458 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6460 * Changed client's channel table to SilcList and changed code
6461 accordingly. Also changed SilcChannelClientEntry to include back-
6462 pointer to the channel so that client entry can use that structure
6463 as list as well and we have fast cross-reference to the channel.
6464 This change dramatically decreased the complexity of channel
6465 handling with client entry and vice versa (removed one extra
6466 loop when searching for channel entry from many functions).
6468 * Changed server->sim from table to SilcDList and changed code
6471 * NAMES command can now be used from user interface. It will show
6472 the user list on the channel, neatly.
6474 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6475 Code now saves realname of the user if it becomes available.
6477 * Renamed configure.in to configure.in.pre and made ./prepare
6478 script to automatically add correct version string to
6479 configure.in which it creates from configure.in.pre.
6481 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6483 * NAMES command reply now shows users mode with the nickname when
6486 * Moved silc_client_ch[u]mode[_char] functions from
6487 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6488 place sucks, they are utility functions and should be in some
6491 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6493 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6496 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6500 * Added TRQ (efficient deque and list library) into lib/trq. This is
6501 a very good list library that is currently used in the SILC. Defined
6502 SilcList API over the library because I didn't like the API very
6503 much. See lib/trq/silclist.h for the API and examples of how to
6504 use the API. Fixed various places in the code to use the new
6505 SilcList API. The SilcList is meant for lists that has a structure
6506 already defined as a list. It is not suitable to add just some
6507 context to the list (in TRQ, the context is the list actually).
6509 So, I defined SilcDList that can be used for the purpose where
6510 predefined list structure does not exit. This can be used as
6511 such list. Now some context just can be added to the SilcDList.
6512 Currently this list is not used in the SILC just yet, though there
6513 are a lot places where this can replace dynamically allocated
6514 tables and I will fix these places, later, to use SilcDList.
6515 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6516 and use TRQ internally).
6518 Also fixed some annoying warning messages that the original TRQ
6519 code generated. Also minor changes to TRQ's Makefile.in.
6521 * Added support for querying by Client ID to both WHOIS and
6522 IDENTIFY commands into server, as required by the protocol.
6524 * Removed method function pointers from SilcBuffer structure. They
6525 weren't used to anything and just increased the context size for
6526 no good reason. This change also made silc_buffer_alloc and
6527 silc_buffer_free functions inline functions.
6529 * Disabled command flooding detection support until it's fixed so
6530 that it accepts commands in but does not execute them more than once
6533 * Added silc_net_localhost(), to return local hostname, into
6534 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6535 that must be initialized before calling silc_client_init.
6537 * Added new function: silc_server_send_notify_on_channels to send
6538 notify messages to all channels client has joined. It is assured
6539 that the message is sent only once per client.
6541 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6542 lib/silcutil/silcutil.[ch] as silc_format function. The new
6543 function is generic and is used by server as well, not only by
6544 the logging routines.
6546 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6547 the provided version string was not acceptable. Added new function:
6548 silc_ske_check_version into lib/silcske/silcske.h. The function
6549 must be implemented by the application (client or server) and it
6550 does not reside in the SKE library. The function checks the version
6551 string remote end sent.
6553 * Added back pointers (to opaque context and to SilcSocketConnection)
6554 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6556 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6557 duplicate packet context structure.
6559 * Changed `notify' client operation to send same arguments as client
6560 receives from server except for ID's. ID's are mapped to correct
6561 ID entry and that is returned. Also, if channel entry is not sent
6562 by server but the notify is for channel the channel entry is sent
6563 to application (otherwise application doesn't know that it is for
6564 channel (library gets it from packet's Destination ID)).
6566 * Added silc_client_remove_from_channels into client library to
6567 remove a client from all channels it has joined to. Used when
6568 received SIGNOFF notify from server. Added also new function
6569 silc_client_replace_from_channels to replace old ID entry with
6570 new ID entry on all channels. Used when received NICK_CHANGE
6573 * Fixed ID Cache list handling in silc_idlist_get_client in
6574 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6575 to get (or query) client by ID.
6577 * Updated TODO list.
6579 * Added connection authentication status message defined by the
6580 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6581 support for these into the code in client and server side.
6583 * Added generic function silc_client_send_command to send any command
6584 with variable argument list. Application should use this function
6585 to send commands if the command functions provided by the library
6586 does not suite for the application's user interface needs.
6588 * Added new `failure' client operation. Application is notified about
6589 received failure packet if client is executing a protocol. In this
6590 case the protocol's execution has failed.
6592 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6593 is required by the protocol.
6595 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6596 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6599 * Added status flag to SilcSKE object to indicate realtime status
6600 of the SKE protocol.
6602 * Application receives now exactly same command reply arguments as
6603 the library receives from server. However, if ID is received the
6604 corresponding ID entry is returned to the application (eg. Client
6605 ID is mapped to correct SilcClientEntry entry and that is returned).
6606 Changed command_reply client operation due to this change.
6608 * Changed all ID's in commands and in command replys as ID Payloads.
6609 Change affected both client and server side codes.
6611 All ID's sent in SILC network (with execption of ID's in SILC
6612 Packet header) are sent in ID Payload to support variable length
6615 * Server now notifies nick changes and notifies all clients on
6616 the channels about the new nickname (about the new Client ID,
6619 * Implemented CMODE command to change channel modes. Supports all
6620 channel modes defined by the protocol specs except ban and invite
6621 lists. (Also, private channel key mode is supported but support for
6622 setting private channel key in client is missing, thus, this mode
6623 has no effect on client side (except that server requires that the
6624 client uses private channel key and normal channel traffic does not
6627 Also, invite mode works per se, but INVITE command does not work
6628 yet correctly, so you can set channel as invite only channel but
6629 inviting clients to the channel does not work (it is yet to be
6630 thought what's the best way to do it).
6632 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6633 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6634 Implemented CUMODE command to change user's mode on the channel.
6635 Supports all modes defined by the protocol specs.
6637 * Added NAMES command reply to return users modes on the channel.
6639 * Removed unnecessary and slow ciphers from lib/silccrypt.
6641 * Set SO_KEEPALIVE option to connection sockets by default.
6643 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6645 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6646 redefined the Notify Payload into protocol specs.
6648 * Added silc_id_payload_parse_id to get ID directly from raw
6651 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6653 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6654 accept searching by Client ID as well.
6656 * Added support for LEAVE and SIGNOFF notify types in client library.
6658 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6659 to parse ID Payload from raw data.
6661 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6663 * Added flags parameter into silc_ske_assemble_security_properties
6664 function in lib/silcske/silcske.[ch].
6666 * Changed notify client operation to fit better for notify messages
6667 sent by server. The notify payload received from server is now
6668 passed to the application (after parsing it to SilcNotifyPayload).
6669 It is application's responsibility to retrieve the arguments
6670 from the payload and show the message the way it wants. The message
6671 sent by server is implementation specific.
6673 * Changed public keys to comply with the protocol specification.
6674 Old public keys are not supported anymore and are not compatible.
6676 * Removed nickname from Channel Payload as the latest draft removed
6677 it. The client must resolve the nickname from the NAMES command
6678 reply received when it joined the channel.
6680 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6682 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6684 * Fixed some errors in protocol specification drafts.
6686 * Created lib/silccore/silcnotify.c to implement Notify Payload
6687 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6688 generic payloads described by protocol specifications. The file
6689 includes implementations for ID Payload and Argument Payload.
6691 * Changed Command Payload implementation to use the new Argument
6692 Payload. Changed command_xxxx_payload to command_payload_xxxx
6693 to comply with SILC coding conventions.
6695 * Added suppport for Argument Payload handling in Notify Payload
6696 implementation as protocol requires it. Added the new support
6697 into server and client lib as well.
6699 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6701 * Added support for multiple nicknames on same channel. [n] is
6702 added locally to the nickname if there are more than one same
6703 nicknames on the channel.
6705 * Server now sends all nicknames that matched WHOIS request.
6706 Client also shows the list received from server.
6708 * Added TOPIC command to client side. User can now set and show
6709 current topic on channel.
6711 * Added MOTD command to client and server. Also, server sends the
6712 motd when client connects to the server.
6714 * Changed version strings to comply ISO 8601.
6716 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6718 * Fixed protocol error handling in client library. It should now
6719 cope even if the SKE fails for some reason.
6721 * Made new protocol specification drafts for submitting to IETF.
6723 * Implemented TOPIC command to server in silcd/command.c.
6725 * Added two new notify types into lib/silccore/silcnotify.h:
6726 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6727 notify nickname change and topic setting/change on a channel.
6729 * API change of command_reply operation in client library. The
6730 application gets now the status type received from server as well.
6732 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6734 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6736 * Cras fixed and optimized the packet handling even further and
6737 it should work now. Minor change to the prototype of function
6738 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6740 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6742 * Added new function into lib/silcutil/silcschedule.[ch]:
6743 silc_schedule_with_fd to select() a specified fd. The function
6744 returns after timeout expires or data arrives or goes. The
6745 function is used by packet routines to wait that all data is
6746 received from network.
6748 * Fixed data reading from network in lib/silccore/silcpacket.c.
6749 The code now assures that all data is read from the fd and then
6750 continues packet processing. This was a bug fix since the code
6751 used to drop some data in some circumstances.
6753 * Added new function into lib/silcclient/client.[ch]:
6754 silc_client_start_key_exchange to start key exchange after
6755 connection has been established to server. The code internally
6756 now uses this funtion but its main purpose was to provide it
6757 for applications that perform their own connecting. After
6758 application has created a connection it merely calls this
6759 function to start the key exchange between client and server.
6760 The library takes care of everything else after that.
6762 Updated also lib/silcclient/README to explain the usage of
6765 * Do not send to application information that connection has
6766 been established. Application gets notified it by connect
6769 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6771 * Applied cras's patch to add silc_schedule_one function. The
6772 function runs scheduler once and returns.
6774 * Fixed the scheduler after cras messed it up. The timeout
6775 handling works now as it's supposed to work.
6777 * Added into lib/silccore/ silcnotify.h to include notify
6778 message types support. Changed silc_server_send_notify*
6779 functions, in server.[ch], to support those new notify types.
6780 Added the support for the notify types into client library,
6781 as well. Added new notify client operation into ops.h in
6784 * Changed silc_server_packet_send_to_channel to send normal
6785 packets instead of just channel message packets. The function
6786 is now used to send the notify packets to channels. It is not
6787 used to send channel message packets anymore, as server never
6790 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6791 va_arg()s as it seems to require it nowadays. I guess, if SILC
6792 is compiled with older va_arg() the new code should work anyway.
6794 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6796 * Splitted core library. Core library (lib/silccore) includes
6797 now only SILC protocol specific core (and common) components.
6798 Created new utility library (lib/silcutil) that includes more
6799 generic purpose stuff. The stuff for util library was taken
6800 from the old core library. This was minor and easy split.
6802 * Created SILC Client Library (lib/silcclient) that includes
6803 implementation of the SILC client without user interface. This
6804 was major move from silc/ directory. The code has been changed
6805 so that it is transparent towards the user interface. The
6806 silc/ directory includes now the same user interface as before
6807 and it uses the new client library. Read lib/silcclient/README.
6808 Basicly, the client library performs everything else related
6809 to SILC except user interface handling. Also, configuration
6810 files are considered to be part of user interface and library
6811 does not handle them.
6813 This change also changed a lot of structures, function naming etc.
6814 Most important change was that SilcClientWindow object was
6815 renamed to SilcClientConnection in the client library. Created
6816 also new file lib/silcclient/ops.h. Also added new files
6817 silc/local_command.[ch] and silc/client_ops.[ch].
6819 All these changes were made to make it easier for user interface
6820 designers to create what ever user interface for the SILC client
6823 It is also expected that the server will be moved to lib
6824 directory as well and SILC Server Library will be created;
6825 sometimes in the future.
6827 * Removed Local commands from lib/silccore/silccommand.h as
6828 they are application specific and new client library does not
6829 handle any of those anymore.
6831 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6832 old client implementation in silc/.
6834 * Added support for callback functions in SILC_LOG_* macros.
6835 Application can now set its own callbacks that will be called
6836 instead of using the default functions that will always print
6837 the debug messages to stderr (or stdout). Also, debugging can
6838 now be disabled by setting silc_debug to FALSE and re-enabled by
6839 setting it to TRUE. Note, that logging will still work even
6840 if debugging is disabled.
6842 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6843 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6844 silc_log_reset_debug_callbacks.
6846 * To enable debugging in silc client one must give now -d
6847 option on command line.
6849 * Changed silc_schedule_init to automatically allocate task queues
6850 if they are not allocated before calling it.
6852 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6854 * Added GMP 3.1 into math library.
6856 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6858 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6859 a channel in SILC network. The packet is used by servers and
6860 routers to notify other routers that user has left a channel.
6861 This little feature was missing until now. Added the feature
6862 to protocol specification as well.
6864 Added functions: silc_server_send_remove_channel_user and
6865 silc_server_remove_channel_user into server.[ch].
6867 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6868 lib/silccore/silcpacket.h. However, they are not implemented
6871 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6873 * Fixed joining to a channel and sending channel messages
6874 between server and router. The channel message sending should
6875 now work inside a cell.
6877 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6879 * Fixed the private message sending between server and router.
6880 The private message sending should now work inside a cell.
6882 * Added silc_server_replace_id into server.[ch] to replace
6883 existing ID in the SILC network.
6885 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6886 and silc_idlist_replace_server_id into idlist.[ch] in server.
6888 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6890 * Fixed the server to server connections. Server can again now
6891 connect to router. Router to router connections probably does
6894 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6896 * Added dynamic protocol registering support. Now protocols can
6897 registered and unregistered on the fly. Patch by cras.
6899 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6901 * Added lib/contrib directory to hold routines that some platforms
6902 don't have but are needed by SILC.
6904 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6905 into lin/contrib to provide getopt() and getopt_long() for
6906 those who don't have it.
6908 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6910 * Added AWAY command to client. When away message is set and
6911 client receives a private message packet the client automatically
6912 replies to the sender with the away message.
6914 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6915 bug seemed to be the cause of recent problems when compiling
6918 * Added version detection support to SKE protocol specification
6919 and added the new changes to the SKE implementation as well.
6920 There were other minor changes in the SKE protocol as well.
6922 Many changes in lib/silcske/silcske.[ch] and in
6923 lib/silcske/payload.[ch].
6925 * Added ^U functionality, clear input line. Patch from cras.
6927 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6929 * Mainly small bugfixes on core library. Fixed some debugging
6930 logging and buffer overflow in silclog.c.
6932 * Updated config.sub and config.guess on the distribution tree.
6934 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6936 * Added command lagging support in server. Client may execute
6937 commands now only once in two seconds.
6939 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6941 * Optimized packet reception. MAC computation and checking is now
6942 also more optimized. A lot previously duplicated code is now
6943 used as generic by both client and server.
6945 * Fixed key pair generation in clientutil.c
6947 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6949 * Added into lib/silccore/silcbufutil.[ch] new function;
6950 silc_buffer_realloc.
6952 * Moved generic packet sending/encryption functions to
6953 lib/silccore/silcpacket.[ch] from client and server. Some
6954 rewriting of the functions.
6956 * Moved all generic packet reception/decryption functions to
6957 lib/silccore/silcpacket.[ch] from client and server. The
6958 packet processing is now much cleaner in both client and server.
6959 These were major changes in both client and server.
6961 * Created many common functions in server to do packet sending.
6962 Previously code were duplicated a lot, this has been removed
6965 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6967 * Rewrote major parts of the ID cache system. Don't know
6968 whether it is better now or not but at least the API is more
6971 * Major rewrite on ID cache stuff on client because of the ID
6972 cache API changes. Added idlist.c to client.
6974 * Also major rewrite on ID cache stuff on server as well.
6975 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6976 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6977 in hand, instead they are all put into the ID cache system now.
6978 All server_idlist_* routines uses ID cache now instead of
6979 traversing its own lists (those lists does not exist anymore).
6980 SilcIDList though still exists. Also, SilcXXXEntry's are
6983 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6985 * Finally made the SKE implementation compliant to the protocol
6986 specification. All mp integers are now binary encoded as
6987 opposed being HEX encoded.
6989 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6992 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6993 functions: silc_[encode/decode]_pem. Also added function
6994 silc_encode_pem_file to PEM encode with newlines ('\n') for
6997 * SILC public keys are now encoded either PEM or binary. Same
6998 option is for private keys as well. By default private keys
6999 are binary encoded and public keys PEM encoded. Silly HEX
7000 encoding were removed.
7002 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7003 function to create fingerprints.
7005 * Fixed a bug in SHA1; does not change the original data anymore.
7007 * Partly implemented INFO command on client and server side.
7008 Fixed CLEAR command. Changes to SERVER command; show current
7009 server(s) when giving command without arguments. Added
7010 VERSION command to client.
7012 * Added check to server that unregistered connections cannot
7013 execute commands (unless it is specificly allowed).
7015 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7017 * Fixed screen refresh.
7019 * Fixed channel joining bug from client. On some circumstances
7020 client tried to join to a channel it had already joined.
7022 * Added public key verification process into client's protocol.c.
7023 The client now verifies the public key from user and saves
7024 it into ~./silc/serverkeys/ directory.
7026 Added into: clientutil.[ch]: silc_client_verify_server_key.
7028 * Changed SKE protocol's silc_ske_initiator_finish function
7029 to accept callback function that verifies the received public
7030 key. Removed old silc_ske_verify_public_key function.
7032 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7034 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7035 silc_pkcs_private_key[_data]_set.
7037 * Made the password and public authentication more cleaner in
7038 server's protocol.c.
7040 * Removed historic and obsolete protocol `channel_auth' from
7041 both client and server.
7043 * Removed wrong way of sending command status messages from
7044 server to client in server's command.c. The old way violated
7045 protocol specification.
7047 Changes to silccore/silccommand.[ch]: removed
7048 silc_command_encode_status_payload -> not needed anymore,
7049 changed silc_command_encode_payload_va to accept extra
7050 argument on variable argument list. The argument type must
7051 now be provided to the function. Also, added new function:
7052 silc_command_encode_reply_payload_va which is same as
7053 normal command_encode_payload_va except command status type
7054 is provided as extra argument.
7056 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7058 * Added ~./silc directory handling. The directory includes the
7059 public and private keys for the client.
7061 Added silc_client_check_silc_dir, silc_client_create_identifier
7062 and silc_client_load_keys.
7064 * Implemented SILC protocol compliant public key. Added public
7065 and private key saving to and loading from files.
7067 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7068 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7069 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7070 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7071 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7073 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7074 silc_pkcs_load_[public/private]_key.
7076 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7078 * Added silc_server_get_route (route.[ch]) to get connection
7079 data for the fastest route for given ID.
7081 * Implemented INVITE command on client and server. The command
7082 were re-defined in the SILC Protocol Specification and the
7083 implementation now complies with the specification.
7085 * Implemented PING command on client and server.
7087 * Implemented NAMES command on client and server. The server side
7088 supports currently only normal server not router server yet.
7089 Some changes to NAMES definition in SILC protocol specification.
7091 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7093 * Implemented LEAVE command on client and server.
7095 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7096 again. This change was made to the protocol as well. Server
7097 should not violate the protocol specification anymore.
7099 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7101 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7102 was tested. SOCKS4 was not but should work anyway.
