13 * Added new configuration options and blocks:
14 keepalive_secs, reconnect_count, reconnect_interval,
15 reconnect_interval_max, reconnect_keep_trying and
16 require_reverser_lookup. Added ConnectionParam block, and
17 implemented the connection parameters when connecting as
18 initiator and when accepting connections as responder.
20 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
21 whether given configuration value has been given already.
23 Affected files silcd/serverconfig.[c], server.[c].
25 * Splitted the doc/example_silcd.conf.in. Separated the crypto
26 algorithm parts and created new file silcalgs.conf, that
27 is now included from the example_silcd.conf.in.
29 * Optimized the silc_server_connect_to_router_second to take
30 the connection configuration object from the SilcServerConnection
31 object instead of finding it during the connecting phase.
32 Added the configuration object to SilcServerConnection struct.
33 Affected files silcd/server_internal.h, server.c.
35 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
37 * Add the client on channel after it was resolved at the
38 channel message receiving, and it was not already on the
39 channel. Affected file lib/silcclient/client_channel.c.
41 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
43 * Fixed the public key authentication to allocate always the
44 destination signature buffer instead of using static buffer.
45 Affected file silcd/protocol.c.
47 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
49 * Unified the serverconfig.[ch]'s helper function interface.
50 Affected file silcd/serverconfig.[ch].
52 * Removed doc/example_silc.conf.in since it is redundant.
53 The make install will now install irssi/silc.conf file.
55 * Added new Passphrase and Publickey authentication methods to
56 config file, allowing both public key and passphrase based
57 authentication to be set at the same time.
59 Added `prefer_passphrase_auth' setting in config file which
60 can be used to set to prefer passwd auth if both passwd and
61 public key is set. If not set, public key is preferred.
62 This has effect only when being initiator (responder will try
65 Added support for authentication with passphrase and public key
66 at the same time. The passphrase is tried first always since
67 it is faster to check.
69 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
71 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
73 * Merged the new SILC Config library, with the server parsing
74 support. Read the header file silcconfig.h or the toolkit
75 documentation for the news. Affected files are
76 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]

98 Payload. Affected file lib/silccore/silcchannel.c.
100 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
103 * Removed lib/silcclient/README and created HTML file
104 lib/silcclient/silcclient_using.html, which is now included
105 as part of Toolkit documentation.
107 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
109 * Fixed CUMODE_CHANGE notify handling to change the mode of
110 correct client. Affected file lib/silcclient/client_notify.c.
112 * Make silc_rng_alloc fail if it cannot allocate the sha1
113 hash algorithm. Affected file lib/silccrypt/silcrng.c.
115 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
117 * Fixed the file transfer's key agreement payload to include
118 zero port also if the hostname is NULL because it could not
121 Call file transfer monitor callback now also if error occurs
122 during key agreement protocol.
124 Changed the silc_client_file_send interface to return the
125 SilcClientFileError instead of session id. The session ID
126 is returned into pointer provided as argument.
128 Check that the file exists locally before sending the
129 file transfer request at all.
131 Affected file lib/silcclient/client_ftp.c, silcapi.h.
133 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
134 error than can occur while key agreement protocol. Affected
135 file lib/silcclient/silcapi.h.

138 is changed and +k mode is set in the channel. Affected file
139 irssi/src/silc/core/silc-channels.c.
141 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
142 SILC_LOG_WARNING to give out Warning and not Error. Affected
143 file lib/silcutil/silclog.c.
145 * Fixed the channel message payload decryption in the function
146 silc_channel_message_payload_decrypt to not modify the original
147 buffer before it is verified that the message decrypted
148 correctly. Otherwise, next time it is called with correct
149 channel key it won't encrypt since the payload is corrupted.
150 Affected file lib/silccore/silcchannel.c.
152 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
154 * Do not constantly resize the window. A fix patch by cras.

162 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
164 * Fixed a bug in hash table internal routine for traversing
165 the table with foreach callback. The current entry may
166 become invalid in the callback but it was referenced after
167 the callback returned.
169 Do not allow auto rehashing of hash table during the
170 silc_hash_table_foreach operation, for same reasons as it is
171 not allowed for SilcHashTableList. Affected files are
172 lib/silcutil/silchashtable.[ch].
174 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
176 * Defined DLLAPI into silcincludes.h and silcwin32.h for
177 Win32 DLL. extern's in header files are now declared with
180 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
182 * Fixed private message handling. It used some old code that
183 caused the client to crash. Affecte file is
184 lib/silcclient/client_prvmsg.c.
186 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
188 * Added function silc_client_add_channel,
189 silc_client_replace_channel_id, and removed functions
190 silc_client_new_channel_id and silc_idlist_get_channel_by_id
193 * Added cross reference of the joined channels to the
194 SilcClientEntry, and changed the SilcChannelEntry's
195 users list to SilcHashTable. The affected files are
196 lib/silcclient/idlist.[ch].
198 * Fixed a bug in hash table tarversing. While the hash table
199 is traversed with SilcHashTableList the table must not be
200 rehashed. It is now guaranteed that auto rehashable tables
201 are not rehashed while tarversing the list. Also defined that
202 silc_hash_table_rehash must not be called while tarversing
203 the table. Added function silc_hash_table_list_reset that must
204 be called after the tarversing is over. The affected files are
205 lib/silcutil/silchashtable.[ch].
207 * Changed all hash table traversing to call the new
208 silc_hash_table_list_reset in server and in client library.
210 * Added function silc_client_on_channel to return the
211 SilcChannelUser entry if the specified client entry is joined
212 on the specified channel. This is exported to application as
213 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
215 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
217 * Fixed founder regaining problem with JOIN command on normal
218 server. The notify for mode change must be sent always and
219 not only if !cmd->pending. Affected file silcd/command.c.
221 * Fixed the WHOWAS command's reply sending to support the
222 lists correctly. Affected file silcd/command.c.
224 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
226 * When sending JOIN command to router for processing the
227 sender's old command identifier was not saved back to the
228 sender's command context, fixed now. The affected file is
231 * Create the key in JOIN command of the router did not return
232 the channel key, added check for this. Affected file is
235 * Fixed a channel ID update bug in JOIN command reply. Do
236 not directly upgrade the ID but call the function
237 silc_idlist_replace_channel_id if the ID was changed.
238 Affected file silcd/command_reply.c.
240 * Fixed memory leaks from command calling if it would fail.
241 Affected file silcd/command.c.
243 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
245 * Applied patches from cras:
247 Memory leak fixes around libaries, irssi window resize fix,
248 new silclist.h and silcdlist.h, all extern inline changed to
251 * Removed dotconf from lib/dotconf, not needed anymore.
253 * Removed TRQ from lib/trq, not needed anymore.
255 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
256 with server connections. Later this will be configurable
257 in config file after new config file is done. Affected file
260 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
262 * Fixed a crash in server related to channel announcements.
263 Affected file silcd/server.c.
265 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
267 * Fixed memory leaks in silc_server_create_new_channel*
268 functions. Affected file silcd/server.c.
270 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
271 which ID was changed. This way the router will send the
272 user list for the channel again, and server won't be in
273 desync in some rare circumstances. Affected file is
274 silcd/packet_receive.c.
276 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
278 * Check for NULL socket pointer in the function
279 silc_server_packet_send_to_channel_real. Affected file

283 list. Affected file silcd/packet_receive.c.
285 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
287 * Fixed some header addition to Toolkit distribution in
288 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
290 * Added lib/silcclient/client_ops_example.h as an template
291 file for application programmers to quickly start using
292 the SilcClientOperation functions in their application.
293 Updated the lib/silcclient/README as well to tell about this
294 nice file made available.
296 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
298 * Call silc_server_remove_from_channels when removing client
299 entry when NO_SUCH_CLIENT_ID was received. Affected file
300 is silcd/command_reply.c.
302 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
304 * Added server & router operator statistics updating. Affected
305 file silcd/packet_receive.c and silcd/command.c.
307 * Fixed the SERVER_SIGNOFF notify handling on normal server
308 not to save the history information for clients. Same was
309 fixed earlier in remove_clients_by_server function, but not
310 here. Affected file silcd/packet_receive.c.
312 * Raised the default connection-retry count from 4 to 7 in
313 server. Affected file silcd/server.h.
315 * Cancel any possible reconnect timeouts when we start the
316 key exchange. Affected file silcd/server.c.
318 * Do not reconnect on connection failure when SCONNECT was
319 given. Affected files silcd/server.[ch].
321 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
323 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
325 * Fixed the NICK command to always give the unformatted
326 nickname to the one giving the NICK command. If unformatted
327 nickname is cached already it will be formatted and the
328 local entry will always get the unformatted nickname.
329 Affected file lib/silcclient/idlist.c.
331 * Fixed some double frees from client library commands.
332 Affected file is lib/silcclient/command.c.
334 * Fixed CUMODE command in server to assure that no one can
335 change founder's mode than the founder itself, there was a
336 little bug. Affected file silcd/command.c.
338 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
340 * Removed the SilcClientCommandDestructor from the client
341 libary, it is not needed anymore. Affected files are
342 lib/silcclient/silcapi.h, command[_reply].[ch],
343 client_notify, idlist.c.
345 * Fixed GETKEY command to first resolve client, and then
346 resolve the server only if the client was not found, instead
347 of resolving both at the same time. Affected file is
348 lib/silcclient/command.c.
350 * Added silc_client_start_key_exchange_cb and lookup the
351 remote hostname and IP address before starting the key
352 exchange with server. The affected file is
353 lib/silcclient/client.c.
355 * The server's public key is now saved using the IP address
356 of the server and not the servername for the filename.
357 The hostname public key filename is checked as an fall back
358 method if the IP address based filename is not found.
360 Fixed the GETKEY command to save the fetched server key
363 Print the remote server's hostname now when new key is
364 received during connection process. Affected file is
365 irssi/src/silc/core/client_ops.c.
367 * Return always our own public key to the client if it asks
368 for it with GETKEY command. Affected file silcd/command.c.
370 * Removed the use_auto_addr variable from default config
371 file since it was in wrong section. Affected file is
374 * Fixed TOPIC_CHANGE notification to not route it when it
375 was sent using silc_server_send_notify_to_channel function.
376 Affected file silcd/command.c.
378 * Fixed silc_server_send_notify_kicked to send the kicker's
379 Client ID also, it was missing. Affected files are
380 silcd/command.c, silcd/packet_send.[ch].
382 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
384 * Do not save client history information in SERVER_SIGNOFF.
385 Fixes the bug in normal server that it does not detect
386 the client becoming valid after the server becomes back
387 online. Affected file silcd/server_util.c.
389 * Added `sock_error' field into the SilcSocketConnection
390 context. When error occurs during socket operation (read
391 or write) the error is saved. Added also new function
392 silc_socket_get_error to return human readable socket error
393 message. Affected files are lib/silcutil/silcsockconn.[ch],
394 lib/silcutil/unix/silcunixsockconn.c, and
395 lib/silcutil/win32/silcwin32sockconn.c.
397 * The server now prints the socket error message in the
398 signoff for client. Affected file silcd/server.c.
400 * Fixed the `created' channel information sending from router
401 to server in JOIN command. Checks now whether the channel
402 really was created or not and set it according that.
404 Fixed the JOIN command to use the client entry's current
405 ID during the joining procedure instead of the one it sent
406 in the command (it is checked though), since it can change
407 between the packet processing and command processing, and
408 would just case unnecessary pain in the client end. Affected
409 file silcd/command.c.
411 * Fixed a channel key payload sending to use correct channel
412 ID when the server was forced to change the channel's ID by
413 router. Router sent the key payload with the old Channel ID.
414 Affected file silcd/packet_receive.c.
416 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
418 * Call silc_server_save_channel_key only if the key payload
419 was provided in the JOIN command's command reply. Affected
420 file silcd/command_reply.c.
422 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
424 * Fixed silc_mp_sizeinbase to return the value correctly with
425 MPI. Affected file lib/silcmath/mp_mpi.c.
427 * Fixed the stop_server signal to correctly stop the scheduler
428 and gracefully stop the server when SIGTERM or SIGINT signals
429 are received. Affected file silcd/silcd.c.
431 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
433 * Simple handling of TERM and HUP signals. Also added some log
434 flushing call around. Affected file is
437 * Fixed small bugs in silclog.c. Now buffering output will take
438 effect after 10 seconds since startup: This will ensure that
439 no important startup messages are lost. Also output redirection
440 will preserve original format ([Date] [Type] message).
441 Affected file is lib/silcutil/silclog.c.
443 * Added two options to the config file, in the logging section:
444 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
445 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
447 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
449 * Do not print the warning about log files not being initialized
450 more than once to avoid excess logging. Affected file is
451 lib/silcutil/silclog.c.
453 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
454 the SIM copying in make install in Makefile.am.pre.
456 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
458 * Rewritten silclog APIs. Globally interesting changes follows:
459 silc_log_set_files() changed to silc_log_set_file().
460 silc_log_set_callbacks() changed to silc_log_set_callback().
461 ROBOdoc documented silclog header file.
462 SilcLogCb now returns bool to wether inihibit the default
463 handler or not (to keep the old behaviour return always TRUE).
464 The new APIs should also fix the problem of the
465 silcd_error.log file that was written in the current directory.
468 Log files streams will remain opened after silc_log_set_file()
469 call, means less CPU usage notably on high traffic servers.
470 File streams are now full buffered, and flushed to the disk
471 every 5 minutes, lesses HD activity and CPU usage.
472 Messages can be redirected, allowing admins to configure
473 one single logfile for all server messages.
474 the silc_log_quick global variable to activate fast-logging.
475 Affected files lib/silcutil/silclog.[ch]
477 * Changed some code to conform new silclog APIs. Affected
478 files are doc/example_silcd.conf.in, silcd/server.c
479 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
482 * Fixed a memory leak that could occur in some situations.
483 Affected file silcd/serverconfig.c.
485 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
487 * Added the silc_client_del_client to remove the client from
488 all channels as well. Affected file lib/silcclient/idlist.c.
490 * Fixed the client library to correctly remove the client
491 from all channels when the client entry is being destroyed.
492 Affected file lib/silcclient/client_notify.c, command.c.
494 * Added auto-nicking support to the client library. If the
495 applicatio now sets client->nickname it will be sent to the
496 server after connecting by the library. This way for example
497 SILCNICK (or IRCNICK) environment variables will have effect
498 and always change the nickname automatically to whatever
499 it is wanted. Affected file lib/silcclient/client.[ch].
501 * Renamed silc_server_command_bad_chars to the
502 silc_server_name_bad_chars and moved it to the
503 silcd/server_util.[ch]. Added also new function
504 silc_server_name_modify_bad to return nickname that
505 includes bad characters as new nickname without those
506 bad characters. This check and modify is now used in
507 silc_server_new_client when the username is initially set
508 as nickname, so it must be checked to be valid nickname.
509 Affected file silcd/packet_receive.c.
511 * The nickname length is now taken from the packet for real
512 and not trusted to strlen() since it clearly can return
513 wrong length for nickname including bad characters. This
514 also applies to channel names. Affected file silcd/command.c.
516 * Removed the lib/silcsilm/modules directory. Modules are now
517 compiled into the lib/silcsim. Fixed the copying of the
518 modules to follow symbolic links in Makefile.am.pre.
520 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
522 * Fixed silc_string_regexify list creation. Fixes bugs with
523 BAN and INVITE commands in server. The affected file is
524 lib/silcutil/unix/silcunixutil.c.
526 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
528 * Removed the command destructor entirely from the server's
529 command and command reply routines. It is not needed, and
530 its usage was buggy and caused crashes. Affected files are
531 silcd/command[_reply].[ch].
533 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
535 * Cancel protocol and NULL sock->protocol if timeout
536 occurred during protocol. Affected file silcd/server.c.
538 * Cancel protocol timeouts always before calling the final
539 callback, to assure that after final callback is called
540 no other state will be called for the protocol anymore.
541 Affected file silcd/protocol.c.
543 * Print error log if incoming connection configuration could
544 not be found. Affected file silcd/server.c.
546 * Fixed JOIN command to correctly save the founder mode
547 to the client on normal SILC server, when the channel
548 was created by the router. Affected file silcd/command.c.
550 * Fixed LIST command (hopefully) to send correct reply
551 packets. Affected file silcd/command.c.
553 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
555 * The silc_packet_receive_process now returns FALSE if the
556 read data was invalid packet, and TRUE if it was ok.
558 The server now checks that if unauthenticated connection
559 sends data and its processing fails the server will close
560 the connection since it could be a malicious flooder.
562 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
564 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
566 * Make sure the warning about error opening a log file is
567 printed only once and not everytime it fails (produces
568 too much useless log). Affected file lib/silcutil/silclog.c.
570 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
572 * Made the silc_server_daemonise() function more readable.
573 Affected file silcd/server.c.
575 * Pid file is now optional, the user may comment it out from
576 the config file. Removed define SILC_SERVER_PID_FILE, we
577 don't need a default any longer. Affected file
578 configure.in.pre, lib/Makefile.am.pre.
580 * Make some use of the pid file. The server now dies at startup
581 if it detects a valid pid file on his path. The server would
582 die anyway in this circumstance, because of the bind() failure.
583 Affected file silcd/silcd.c.
585 * No longer compiling lib/dotconf.
587 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
589 * Fixed JOIN command parsing not to crash. Affected file
590 lib/silcclient/command.c.
592 * Fied the NICK_CHANGE notify to add the new client entry
593 even it is resolved. This removes an <[unknown]> nick
594 thingy bug in the client. Affected file is
595 lib/silcclient/client_notify.c.
597 * Do not try to allocate 0 bytes (efence does not like it)
598 in lib/silccore/silccomand.c when encoding payload.
600 * Do not take IRCNICK as nickname in Irssi SILC client since
601 it is not possible to set nickname before hand connecting
602 the server (TODO has an entry about adding auto-nicking
605 * Changed the silc_server_command_pending to check whether
606 there already exists an pending entry with the specified
607 command, command identifier and pending callback. This is
608 to fix IDENTIFY and WHOIS related crashes that may register
609 multiple pending commands with same identifier. Affected
610 file silcd/command.c.
612 * Fixed the server to reconnect to the router even if it
613 was already reconnecting and EOF was received. This to
614 fix a possibility that the server wouldn't ever try to
615 auto-reconnect to the router. Affected file silcd/server.c.
617 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
619 * Fixed the server's password authentication to use the
620 length of the locally saved password, and not the one
621 sent in the packet. Affected file silcd/protocol.c.
623 * Fixed same password authentication problem in the
624 Authentication Payload handling routines in
625 lib/silccore/silcauth.c.
627 * Yet another password authentication problem fixed with
628 channel password handling in silcd/command.c.
630 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
632 * If first character of string in silc_parse_userfqdn is '@'
633 then do not parse it. Affected file is
634 lib/silcutil/silcutil.c.
636 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
638 * Fixed minor bug in IDENTIFY command reply sending, which
639 caused various weird problems during JOIN when it was
640 resolving names for users. Affected file silcd/command.c.
642 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
644 * Fixed the IDENTIFY command reply sending to chech better valid
645 clients. It was possible to send incomplete list of replies.
646 Affected file silcd/command.c.
648 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
650 * Added silc_client_command[s]_[un]register functions now to
651 dynamically register the commands in client library. Removed
652 the static table of commands. This allows the client library
653 to call commands without causing the application to know about
654 what commands library has called.
656 Removed the INFO command reply kludge to detect when the command
657 was called by library. Now library use its own command reply
658 function for INFO command.
660 Added function silc_client_command_call to call a command.
661 Application can use it to call command, not access the structure
664 Now all commands that are sent by the client library (not
665 explicitly sent by application) use own command reply functions.
667 Affected files around lib/silcclient/ and in
668 irssi/src/silc/core/.
670 * Fixed the WHOIS command reply sending to chech better valid
671 clients. It was possible to send incomplete list of replies.
673 Fixed the WHOIS and IDENTIFY to send the request to router
674 if normal server did not do it and did not find any results.
676 Affected file silcd/command.c.
678 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
680 * Moved the internal data from SilcClient context into its
681 own file, not accesible to application. Affected files
682 lib/silcclient/client.h and lib/silcclient/client_internal.h,
683 and other files in client library.
685 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
687 * Added doc/examples installation target in Makefile.am.pre.
690 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
692 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
693 commands the found client entry will be removed from the
694 cache, after notifying application about the error. Affected
695 file lib/silcclient/command_reply.c.
697 * Changed the /MSG to check for exact nickname user gave, and
698 not let `nick' match `nick@host' if it is only one found. Now,
699 user must type the exact nickname (like nick@host2) even if
700 there are no more than one same nicks found. This is to avoid
701 a possibility of sending nickname to wrong nickname since
702 `nick' could match `nick@host'. Affected file is
703 irssi/src/core/silc-servers.c.
705 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
707 * Do not print "you are now server operator" or similar when
708 giving /away command. Affected files are
709 irssi/src/silc/core/client_ops.c, silc-servers.h.
711 * Made the silc_server_command_pending_error_check to send
712 the same command reply payload it received back to the
713 original sender of the command. This way all arguments
714 that was received by the server will be received by the
715 client too. Affected file silcd/command.c.
717 * Added the silc_idcache_add to return the created cache entry
718 to a pointer. Affected file lib/silccore/silcidcache.[ch].
720 * Add global clients to expire if they are not on any channel.
721 This is because normal server will never know if they signoff
722 if they are not on any channel. The cache expiry will take
723 case of these entries. This is done by normal servers only.
724 The affected files are silcd/command_reply.c,
725 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
727 * If server receives invalid ID notification for WHOIS or
728 IDENTIFY and the ID exists in the lists, it is removed.
729 Affected file silcd/command_reply.c.
731 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
732 in client then client entry that it matches is searched and
733 the nickname is printed on the screen for user. Affected
734 file irssi/src/silc/core/client_ops.c.
736 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
738 * Use cache entry expire time in the LIST command reply to
739 purge old entries from the cache after the LIST command
740 reply has been received. This way we don't have non-existent
741 entries in the cache for too long. Affected file is
742 silcd/command_reply.c.
744 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
746 * If we are normal server, and we've not resolved client info
747 in WHOIS or IDENTIFY from router, and it is global client,
748 we'll check whether it is on some channel. If it is not
749 then we cannot be sure about its validity and will resolve it
750 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
751 file silcd/command.c.
753 * Search channel by name (if possible) rather than by ID
754 in IDENTIFY command's command reply. Affected file is
755 silcd/command_reply.c.
757 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
759 * Distribute to the channel passphrase in CMODE_CHANGE notify.
760 Updated specs and implemented it. Affected file silcd/command.c,
761 silcd/packet_send.c and silcd/packet_receive.c.
763 * Implemented the <founder auth> payload handling in the JOIN
764 command. If provided all conditions for channel joining
765 except requirement to provide correct passphrase can be
766 overrided by the channel founder. Updated the protocol specs.
767 Affected file silcd/command.c.
769 Added support for founder auth in JOIN command in client
770 library. Fixed the parsing of the JOIN command now to support
771 all options as they should be. The affected file is
772 lib/silcclient/command.c.
774 * Optimized the WHOIS and IDENTIFY commands to send the request
775 to router only if it includes nicknames or other names. If
776 they include only IDs then check the local cache first before
777 routing. Affected file is silcd/command.c.
779 * Added channels topic announcements. Affected file is
780 silcd/packet_receive.c and silcd/server.c.
782 * Fixed the silc_server_send_notify_topic_set to really destine
783 the packet to channel. Affected file silcd/packet_send.c.
785 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
786 library. Affected file lib/silcclient/client_notify.c.
788 * Added UMODE announcements. Affected file silcd/server.c.
790 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
792 * Memory leak fixes in:
794 lib/silcutil/silcsockconn.c
795 lib/silcske/silcske.c
798 lib/silccrypt/silcpkcs.c
799 lib/silccore/silccommand.c
800 lib/silccore/silcidcache.c
805 * ROBOdoc documented the lib/silcske/groups.h file and a
806 bit changed the interface for better.
808 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
810 * Update the client entry context in the ID cache after
811 nick change. Affected file lib/silcclient/command.c.
812 Fixes the CUMODE command when regaining founder privileges,
813 and a little WHOIS problem.
815 * Fixed silc_net_gethostbyname to correctly call the
816 inet_ntop. Affected file lib/silcutil/silcnet.c.
818 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
820 * Added IPv6 support checking to the configure.in.pre, added
821 also --enable-ipv6 option to override the check. Affected
822 file configure.in.pre.
824 * The silc_thread_create now calls the start function
825 directly if threads support is not compiled in. Removes
826 ugly #ifdef's from generic code. Affected files are
827 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
829 * Added silc_net_gethostby[name/addr]_async to asynchronously
830 resolve. Affected files are lib/silcutil/silcnet.[ch].
832 * Added support for rendering IPv6 based server, client and
833 channel IDs. Affected file lib/silcutil/silcutil.c.
835 * Added support for creating IPv6 based server IDs. Affected
836 file is silcd/serverid.c.
838 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
840 * Added silc_net_gethostby[addr/name] into the
841 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
842 routines. Added silc_net_is_ip[4/6]. Affected file is
843 lib/silcutil/unix/silcunixnet.c. All routines that take
844 address as argument now supports both IPv4 and IPv6 addresses.
846 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
848 * Fixed LIST command reply sending in server. Affected file
851 * Server now sends the kicker's client ID in the KICK notify
852 to the kicked client. Affected file silcd/command.c.
854 * The client library now parses the kickers client ID and
855 UI displays it. Affected files lib/silcclient/client_notify.c
856 and irssi/src/silc/core/silc-channels.c, module-formats.c.
858 * Made all payload parsing function prototypes consistent.
859 They all take now const unsigned char * and uint32 pair as
860 the payload data instead of SilcBuffer. Changes all around
861 the source tree. Other unsigned char* -> const unsigned char*
862 changes around the tree as well.
864 * Optimized SFTP client and server packet sending not to
865 allocate new buffer for each packet but to recycle the
866 first allocated buffer. Affected files are
867 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
869 * Optimized the SFTP client to use SilcList instead of
870 SilcDList for requests, because it is faster. Affected file
871 is lib/silcsftp/sftp_client.c.
873 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
874 into lib/silccore/silcid.[ch].
876 Renamed silcpayload.[ch] into silcargument.[ch].
878 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
880 * If client entry is deleted with active key agreement
881 session, abort the session.
883 The silc_client_abort_key_agreement now calls the completion
884 callback with new SILC_KEY_AGREEMENT_ABORTED status.
886 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
889 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
891 * Don't use __restrict in older GCC's. Affected file is
892 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
894 * silc_net_localhost now attempts to reverse lookup the
895 IP/hostname. Affected file lib/silcutil/silcnet.c.
897 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
898 command. It can be used to gain founder privileges at
899 the same time when joining the channel.
901 Defined that the SILC_NOTIFY_TYPE_KICKED send the
902 kicker's client ID as well. Updated protocol specs.
904 Defined that the server must send SILC_COMMAND_IDENTIFY
905 command reply with error status to client who sent
906 private message with invalid client ID.
908 Updated the protocol specification.
910 * Added silc_server_send_command_reply to send any
911 command reply. Affected file silcd/packet_send.[ch].
913 * Added silc_id_payload_encode_data to encode ID payload
914 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
916 * The server now send IDENTIFY command reply with error
917 status if client ID in private message is invalid. Affected
918 file silcd/packet_receive.c.
920 * Save the server key file with server's IP address in
921 the filename instead of hostname. The affected file is
922 irssi/src/silc/core/client_ops.c.
924 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
926 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
929 * Added libtool support for compiling shared objects in
930 lib/silcsim. Affected file configure.in.pre and
931 lib/silcsim/Makefile.am. Original patch by cras.
933 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
935 * Pid file configuration, and server's config file fixes
936 patch by toma. Updated CREDITS file.
938 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
940 * Fixed silc_client_channel_message to not try to decrypt
941 the message twice if it resolved the destination client
942 information. This could cause of dropping one channel
943 message. Affected file lib/silcclient/client_channel.c.
945 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
947 * Added silc_client_run_one into lib/silcclient/silcapi.h and
948 lib/silcclient/client.c. This function is used when the SILC
949 Client is run under some other scheduler, or event loop or
950 main loop. On GUI applications, for example this may be
951 desired to used to run the client under the GUI application's
952 main loop. Typically the GUI application would register an
953 idle task that calls this function multiple times in a second
954 to quickly process the SILC specific data.
956 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
958 * Fixed silc_server_drop() for dropping the supplementary
959 groups as well, this could cause a security hole on some
962 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
964 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
967 * Write PID file after dropping privileges. Added -F option
968 to run server on foreground. A patch by debolaz.
969 Affected files silcd/server.c, silcd/silcd.c.
971 * Fixed MOTD to return the MOTD file server name. Affected
972 file silcd/command.c.
974 * Added INFO command reply handling to the Irssi SILC Client.
975 Affected file irssi/src/silc/core/client_ops.c.
977 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
979 * Fixed the silc_idcache_list_* routines to really support
980 the dynamic list. Fixes a crash. Affected file is
981 lib/silccore/silcidcache.c.
983 * Fixed the LIST command reply to really call LIST command's
984 pending callbacks. Affected file silcd/command_reply.c.
986 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
988 * Update conn->local_entry->nickname after giving NICK
989 command. Affected file lib/silcclient/command.c.
991 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
993 * Added the [pid] option to the silcd configuration file
995 Affected files: serverconfig.[ch] and silcd.c
997 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
999 * Save fingerprint in WHOIS command reply in server.
1000 Affected file silcd/command_reply.c.
1002 * Fixed NICK commands pending callback registration.
1003 Affected file lib/silcclient/command.c.
1005 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1007 * Use ++server->cmd_ident when sending commands in server,
1008 instead of random number. Affected file silcd/command.c.
1010 * Fixed GETKEY command reply to call actually GETKEY pending
1011 command callbacks. Affected file silcd/command_reply.c.
1013 * A bit stricter check for nicknames. Check for same nickname
1014 in NICK command also. Affected file silcd/command.c.
1016 * Do not call INFO command everytime client ID changes, only
1017 during first connecting. Affected file lib/silcclient/client.c.
1019 * Set the new nickname only after successful command reply for
1020 NICK command is returned by server. Affected file
1021 lib/silcclient/command.c.
1023 * Remove nicknames from nicklist during server_signoff notify.
1024 Should fix /NAMES bit more. The affected file is
1025 irssi/src/silc/core/silc-channels.c.
1027 * Added `fingerprint' field to the SilcIDListData in the
1028 silcd/idlist.h to hold the fingerprint of the client's
1031 Send the fingerprint of the client's public key in WHOIS
1034 Affected files silcd/command.c, and silcd/idlist.[ch].
1036 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1037 create fingerprint from given data.
1039 * Show the fingerprint of the client's public key in WHOIS.
1040 Affected files irssi/src/module-formats.[ch] and
1041 irssi/src/silc/core/client_ops.c.
1043 * Format the multiple same nicknames also during JOIN and
1044 NICK_CHANGE notifys. Affected file is
1045 lib/silcclient/client_notify.c.
1047 * Do not print error on screen for invalid private message
1048 payload since it can come if someone is sending private
1049 messages with wrong key. Affected file
1050 lib/silccore/silcprivate.c.
1052 * Fixed multiple concurrent /PING crash. Affected file
1053 lib/silcclient/command.c.
1055 * Changed the wrong ID encoding. All IP addresses must be
1056 in MSB first order in encoded format. They were encoded
1057 wrong and was in LSB format. Affected files are
1058 silcd/serverid.c, lib/silcutil/silcutil.c.
1060 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1062 * Call the `connect' client operation through the scheduler
1063 in case of error. Affected file lib/silcclient/client.c.
1065 * Call the `failure' client operation even if the error
1066 occurred locally during a protocol. Affected file is
1067 lib/silcclient/protocol.c.
1069 * Added support of sending LIST command to router from normal
1070 server. This way normal server can get list of all channels
1071 in the network too. Fixed the channel list sending in the
1072 server too. Affected files are silcd/command.c, and
1073 silcd/command_reply.[ch].
1075 * Added silc_server_update_channels_by_server and
1076 silc_server_remove_channels_by_server. They are used during
1077 disconnection of primary router and in backup router protocol.
1078 Affected file silcd/server_util.[ch], silcd/server.c and
1079 silcd/server_backup.c.
1081 * Fixed channel adding to global list in IDENTIFY command
1082 reply in server. Affected file silcd/command_reply.c.
1084 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1086 * If the incoming packet type is REKEY or REKEY_DONE process
1087 that packet always synchronously. Fixes yet another MAC
1088 failed error on slow (dialup) connections. Affected file
1089 lib/silcclient/client.c and silcd/server.c.
1091 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1093 * Call check_version SKE callback for initiator too. Affected
1094 file lib/silcske/silcske.c.
1096 * Implemented fix for security hole found in the SKE that was
1097 fixed in the specification few days back; the initiator's
1098 public key is now added to the HASH value computation.
1099 Added backwards support for the old way of doing it too, for
1100 old clients and old servers. Affected file is
1101 lib/silcske/silcske.c.
1103 * Enabled mutual authentication by default in SKE. If initiator
1104 is not providing mutual authentication the responder will
1105 force it. This will provide the proof of posession of the
1106 private key for responder. The affected files are
1107 lib/silcclient/protocol.c and silcd/protocol.c.
1109 * Do not cache anymore the server's public key during SKE.
1110 We do mutual authentication so the proof of posession of
1111 private key is done, and if the server is authenticated in
1112 conn auth protocol with public key we must have the public
1113 key already. Affected file silcd/protocol.c.
1115 * Added new global debug variable: silc_debug_hexdump. If
1116 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1117 file lib/silcutil/silclog.[ch].
1119 * Fixed compilation warning due to char * -> const char *.
1120 Affected files lib/silcutil/silcnet.h, and
1121 lib/silccore/silcauth.[ch].
1123 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1125 * Fixed CMODE command when new channel key was created. If
1126 the creation failed the old key was removed. Next time giving
1127 same command would crash the server since the old key was
1128 freed already. Affected file silcd/command.c.
1130 * Fixed the silc_server_announce_get_channels to not crash
1131 on reconnect. Affected file silcd/server.c.
1133 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1135 * Added silc_log_set_debug_string function to set a regex
1136 string to match for debug output. Only the function names,
1137 or filenames matching the given debug string is actually
1138 printed. This way it is possible to filter out those debug
1139 strings that user is not interested in.
1141 Fixed a bug in silc_string_regexify.
1143 Affected files lib/silcutil/silclog.[ch], and
1144 lib/silcutil/unix/silcunixutil.c.
1146 * Changed the -d options in both server and Irssi SILC client
1147 to take the debug string as argument. Affected files
1148 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1150 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1152 * Added silc_hash_babbleprint to create a Bubble Babble
1153 Encoded fingerprint. The encoding is developed by Antti
1154 Huima (draft-huima-babble-01.txt), and it creates human
1155 readable strings out of binary data. Affected file
1156 lib/silccrypt/silchash.[ch].
1158 * Print the babble print now in addition of fingerprint as well
1159 in Irssi SILC client. Affected files are
1160 irssi/src/fe-common/silc/module-formats.[ch],
1161 irssi/src/fe-common/silc/core/client_ops.c.
1163 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1165 * Fixed a security problem found in SKE. The initiator's
1166 public key too is now added to the HASH hash value creation
1167 which is signed by the responder to create the SIGN value.
1168 This will prevent anyone in the middle to lie to the responder
1169 about the initiator's public key. If this is done now, the
1170 man in the middle will get caught. Updated the protocol
1173 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1175 * Better installation directory handling. Configure module
1176 paths and other paths automatically to example_silc* files
1177 in doc/. A patch by toma.
1179 * Fixed compiler warning from MPI library, and from SILC RNG.
1182 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1183 It can be configured with ./configure. A patch by toma.
1185 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1187 * Find correct make to use in prepare-clean. A patch by
1188 toma. Affected file prepare-clean.
1190 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1192 * Added irssi variables use_auto_addr, auto_bind_ip,
1193 auto_bind_port and auto_public_ip.
1195 * Changed the interface for silc_client_send_key_agreement
1196 in lib/silcclient/silcapi.h
1200 irssi/src/silc/core/silc-core.c
1202 lib/silcclient/silcapi.h
1203 irssi/src/silc/core/silc-channels.c
1204 lib/silcclient/client_keyagr.c
1207 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1209 * Added silc_pkcs_public_key_compare to compare two
1210 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1212 * Check that the client who set the founder mode on the
1213 channel is the same client that is giving the founder
1214 mode to itself. It is done by comparing the saved public
1215 key (it is saved even in the authentication is passphrase).
1216 Affected file silcd/command.c.
1218 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1220 * Do not process packet for disconnected socket connection.
1221 Affected file lib/silccore/silcpacket.c.
1223 * Process the DISCONNECT packet through scheduler in the
1224 client library. Affected file lib/silcclient/client.c.
1226 * Fixed the silc_client_packet_parse to not to increase
1227 the packet sequence number if the conn->sock and the
1228 current socket connection is not same. This can happen
1229 for example during key agreement when the conn includes
1230 multiple socket connections (listeners). Affected file
1231 lib/silcclient/client.c.
1233 * The sender of the file transfer request now provides also
1234 the pointer (listener) for the key exchange protocol. If
1235 the listener cannot be created then it sends empty key
1236 agreement and lets the receiver provide the listener.
1238 Added `local_ip' and `local_port' arguments to the
1239 silc_client_file_send. If they are provided they are used,
1240 if not then it will attempt to find local IP address, if
1241 not found or bind fails then the remote client will provide
1244 Affected files are lib/silcclient/client_ftp.c and
1245 lib/silcclient/silcapi.h.
1247 * Extended the FILE SEND command to support defining the
1248 local IP and port for key exchange listener. They are
1249 optional. Affected file irssi/src/silc/core/silc-servers.c.
1251 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1253 * Defined to WHOIS command reply the sending of fingerprint
1254 of the client's public key (if the proof of posession of the
1255 corresponding private key is verified by the server).
1256 Updated to the protocol specification.
1258 * Added support of receiving the client's public key's
1259 fingerprint in command reply in client library. Affected
1260 file is lib/silcclient/command_reply.c, and
1261 lib/silcclient/idlist.[ch].
1263 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1265 * Do not send over 128 chars long nickname to the server
1266 in NICK command. Affected file lib/silcclient/command.c.
1268 * Do not send over 256 chars long channel names to the server
1269 in JOIN command. Affected file lib/silcclient/command.c.
1271 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1273 * Assure that silc_server_close_connection cannot be called
1274 twice for same socket context. Affected file is
1277 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1279 * Send error message to application if opening file for
1280 writing during file transfer fails. Affected file is
1281 lib/silcclient/client_ftp.c.
1283 Remove all file transfer sessions for a client that we're
1284 removing from ID cache.
1286 Affected file is lib/silcclient/client_ftp.c.
1288 * Fixed silc_net_addr2bin to return correct address. Affected
1289 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1291 * Fixed file transfer session removing on signoff notify.
1292 Affected file irssi/src/silc/core/silc-servers.c.
1294 * Added the SilcClientFileError to be returned in the monitor
1295 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1296 Affected file lib/silcclient/silcapi.h.
1298 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1300 * Fixed a crash in silc_client_ftp_free_sessions and
1301 silc_client_ftp_session_free_client. Affected file
1302 lib/silcclient/client_ftp.c.
1304 * Added `disabled' field in the SilcChannelEntry in the server
1305 to indicate if the server entry is disabled. Affected file

1315 * Fixed a crash in client resolving in client_prvmsg.c in
1316 client library. Affected file lib/silcclient/client_prvmsg.c.
1318 * Do not actually remove the client directly from ID cache
1319 during SERVER_SIGNOFF, but invalidate it. This way we
1320 preserve the WHOWAS info for the client. Affected file
1321 silcd/server_util.c.
1323 * Fixed SERVER_SIGNOFF notify handling in the server. The
1324 server is now able to process incoming SERVER_SIGNOFF notify
1325 for a server that it doesn't even know about. It will remove
1326 the clients provided in the notify. Affected file
1327 silcd/packet_receive.c.
1329 * Check for partial packet in data queue after every packet that
1330 was found from the queue. Return and wait for more data if
1331 there is partial data in queue. Affected file is
1332 lib/silccore/silcpacket.c.
1334 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1336 * Added SilcClietFileError enum to indicate error in
1337 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1338 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1339 Affected files lib/silcclient/silcapi.h and
1340 lib/silcclient/client_ftp.c.
1342 * Check that newsize in silc_buffer_realloc is larger than
1343 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1345 * Added better monitor of file transfers. It now monitors
1346 key agreement protocol during the file transfer too. Added
1347 error reporting too. Affected files
1348 irssi/src/silc/core/silc-servers.c,
1349 irssi/src/fe-common/silc/module-formats.[ch].
1351 * Wrote a help file for FILE command.
1353 * Added silc_rng_global_get_byte_fast to get not-so-secure
1354 random data as fast as possible. Random data is read from
1355 /dev/urandom if available and from the SILC RNG if not
1356 available. It is used in padding generation. Affected file
1357 lib/silccrypt/silcrng.[ch].
1359 * All packets in client library are now processed synchronously.
1360 Optimized packet processing a lot. Affected file
1361 lib/silcclient/client.c.
1363 * All server connection packets are processing synchronously
1364 now in server, to optimize packet processing. Affected file
1367 * Include files are installed now only in Toolkit distribution
1368 if make install is given. Affected files: all Makefile.am's.
1370 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1372 * Assure that silc_client_notify_by_server_resolve does not
1373 resolve the client information multiple times. If it cannot
1374 be found by the first it cannot be found at all. Affected
1375 file lib/silcclient/client_notify.c.
1377 * Fixed WHOWAS command reply calling. Affected file
1378 lib/silcclient/command_reply.c.
1380 * Removed all references to silc_idlist_get_client from the
1381 Irssi SILC client since that call is internal call used by
1382 the library. The Irssi SILC client will use now client
1383 retrieval functions found in silcapi.h.
1385 * Fixed a bug in resolving nickname info before sending
1386 private message. It used freed memory. Affected file
1387 irssi/src/silc/core/silc-servers.c.
1389 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1391 * Assure my_channels statistics cannot go negative in server.
1392 Affected files silcd/server.c, silcd/server_util.c.
1394 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1396 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1398 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

1408 * Added silc_net_localip to return local host's IP address.
1409 Affected file lib/silcutil/silcnet.[ch].
1411 * If key exchange or rekey protocol is active for a connection
1412 parse all packets syncronously since there might be packets
1413 in packet queue that we are not able to process without first
1414 processing packets before them. Affected file silcd/server,
1415 lib/silcclient/client.c.
1417 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1418 whether library should continue processing the packet.
1419 Affected file lib/silccore/silcpacket.h.
1421 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1422 SilcSFTPMonitorData to SFTP server to monitor various
1423 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

1430 Added preliminary support for simple client to client one-file
1431 transmission. Affected file lib/silcclient/client_ftp.c,
1432 lib/silccilent/client.[ch].
1434 * Added new local command FILE to the Irssi SILC Client.
1435 It is used to perform the file transfer. It has subcommands
1436 SEND, RECEIVE, SHOW and CLOSE. Affected files
1437 irssi/src/silc/core/client_ops.c,
1438 irssi/src/silc/core/silc-server.[ch].
1440 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1442 * Relay the SILC_PACKET_FTP in the server. Affected files
1443 silcd/server.c and silcd/packet_receive.c.
1445 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1447 * Renamed silc_file_read and silc_file_write to functions

1450 lib/silcutil/silcutil.[ch].
1452 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1454 * Resolve the client info when received private message or
1455 channel message for a client which nickname we don't know.
1456 Affected files lib/silcclient/client_prvmsg.c and
1457 lib/silcclient/client_channel.c.
1459 * Do not crash in /KEY if client is not connected. Affected
1460 file irssi/src/silc/core/silc-channels.c.
1462 * Added SilcClientStatus field to the SilcClientEntry in the
1463 lib/silcclient/idlist.h.
1465 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1466 is incomplete and is being resolved, it won't be resolved
1469 Make sure also that USERS command reply does not resolve
1470 twice information. Affected file is
1471 lib/silcclient/command_reply.c.
1473 Make sure that silc_client_get_clients_by_list does not
1474 resolve twice same information.
1476 * Check for valid client->id in the silc_server_free_client_data.
1477 Affected file silcd/server.c.
1479 * Fixed /GETKEY nick@server not to crash if the server entry
1480 is not found. Affected file lib/silcclient/command.c.
1482 * Fixed the silc_server_check_cmode_rights to check the
1483 requested modes correctly. Affected file silcd/command.c.
1485 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1487 * Better checks for non-printable chars in nick added.
1488 Affected file silcd/command.c.
1490 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1492 * Call the silc_server_udpate_servers_by_server in the
1493 primary router that comes back online in the backup resuming
1494 protocol. Otherwise it routes packets wrong. Affected file
1495 silcd/server_util.[ch], silcd/server_backup.c.
1497 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1499 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1500 lib/silcutil/silcbuffmt.[ch].
1502 * Redefined the SILC packet header to include the padding
1503 length. Affected file lib/silccore/silcpacket.[ch].
1505 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1506 length for maximum padding up to 128 bytes). Affected
1507 file lib/silccore/silcpacket.h.
1509 * Removed all backwards support for old 0.5.x MAC thingies.
1510 The SILC packet header change makes it impossible to be
1511 backwards compatible.
1513 * Send the ENDING packet with timeout in the backup resuming
1514 protocol. This is to assure that all routers has connected
1515 to the primary router. Affected file silcd/server_backup.c.
1517 * Changed the RNG to take the first IV from random data. It
1518 used to take it from zero actually. Changed the RNG also
1519 to use /dev/urandom during session. /dev/random is used
1520 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1522 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1524 * Changed the SILC packet header to have the first two bytes
1525 (the packet length) encrypted. Affected files aroung the
1526 code tree, lib/silccore/silcpacket.[ch]. Removed the
1527 SilcPacketCheckDecrypt callback. It is not needed anymore
1528 since the silc_packet_receive_process will determine now
1529 whether the packet is normal or special.
1531 * Implemented the unidirectional MAC keys. Affected files
1532 lib/silcske/silcske.c, silcd/protocol.c and
1533 lib/silcclient/protocol.c.
1535 * Implemented the packet sequence number to the MAC computation.
1536 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1537 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1538 lib/silcclient/protocol.c.
1540 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1542 * Allow backup router to announce servers. All servers
1543 announced by backup router are added to the global list
1544 automatically. Update hte server's socket to our primary
1545 router also when backup router announces a server.
1546 Affected file silcd/packet_receive.c.
1548 * Do not update the client->router in the function
1549 silc_server_udpate_clients_by_server if the client is on
1550 global list. We might fail to find any specific server
1551 for locally connected clients and local cell clients. They
1552 should still use the `from' and not `to' as client->router.
1553 This fixes backup router resuming protocol. Affected file
1554 silcd/server_util.c.
1556 * Decrease channel statistics count only if the channel
1557 deletion worked. Affected files are silcd/server.c and
1558 silcd/server_util.c.
1560 * Added silc_server_update_servers_by_server to update origin
1561 of all server entries. Used during backup router protocol.
1562 Affected files silcd/server_util.[ch], silcd/server.c. and
1563 silcd/backup_router.c.
1565 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1566 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1567 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1568 lib/silccrypt/silchmac.c.
1570 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Assure that router cannot reroute the same channel message
1573 to the sender. Affected file silcd/packet_receive.c.
1575 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1577 * Made better checks that the channel message is not sent
1578 to the router it came from. Affected file is
1579 silcd/packet_send.c. Fixed memory leak too.
1581 * Announce informations for incoming router connection, but
1582 only after checking if it is replaced by backup router.
1583 Affected file silcd/packet_receive.c.
1585 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1587 * Fixed the backup resuming protocol to work in multiple
1588 router environment. Affected file silcd/server_backup.c.
1590 * Route packet only to one router in the function
1591 silc_server_packet_send_to_channel. Affected file is
1592 silcd/packet_send.c.
1594 * Fixed silc_server_send_notify_dest to set the broadcast
1595 flag. Fixed the silc_server_send_notify_topic to actually
1596 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1597 Affected file silcd/packet_send.c.
1599 * Changed the SFTP Filesystem interface. Changed the
1600 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1601 the filesystem operation function. The SilcSFTPFilesystem
1602 is now a context that is allocated by all filesystem allocation
1603 functions and it already includes the operations structure
1604 and filesystem specific context. It is given as argument
1605 now to the silc_sftp_server_start. This made the interface
1606 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1607 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1609 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1611 * Changed the backup router adding and getting interfaces
1612 in the server. The router that will be replaced by the
1613 specified backup router is now sent as argument. Affected
1614 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1617 * Added silc_net_addr2bin_ne to return the binary form of
1618 the IP address in network byte order. Affected files
1619 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1621 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1623 * Check for existing server ID in silc_server_new_server
1624 and in silc_server_connect_to_router_final and remove the
1625 old entry if it exists. Affected file silcd/packet_receive.c,
1628 * Send the channel message always to only one router, either
1629 in upstream or downstream. Affected file is
1630 silcd/packet_send.c.
1632 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1634 * Wrote the definition of the backup resuming protocol to the
1635 protocol specification.
1637 * Removed one redundant channel key generation from normal
1638 server during joining procedure. Removed one redundant
1639 channel key sending from server to router during joining
1640 procedure. Affected file silcd/command.c.
1642 * Made minor bugfixes to the backup router resuming protocol.
1643 Affected file silcd/server_backup.c, server.c.
1645 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1647 * Added --disable-asm configuration option. Affected files
1648 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1651 * Implemented the backup resuming protocol that is used to
1652 resume the primary router position in the cell after the
1653 primary router comes back online. Affected files
1654 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1655 and silcd/server_util.[ch].
1657 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1659 * Sleep two (2) seconds after sending QUIT command to server.
1660 Affected file lib/silcclient/command.c.
1662 * Assure that if outgoing data buffer is pending do not force
1663 send any data. Affected file silcd/packet_send.c.
1665 * Assure that if outgoing data buffer is pending do not force
1666 send any data. Affected file lib/silcclient/client.c.
1668 * Implemented the backup router support when the primary router
1669 goes down. The servers and routers can now use the backup
1670 router as new primary router without loosing connectivity.
1672 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1674 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1675 in the server to indicate disabled entry. All data read
1676 from the connection will be ignored and no data is sent
1677 for entry that is disabled. Affected files are
1678 silcd/idlist.h, silcd/server.c.
1680 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1682 * Created SFTP client and server test programs in the
1683 lib/silcsftp/tests directory.
1685 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1687 * Implemented memory filesystem (virtual filesystem) for
1688 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1691 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1693 * Implemented the SFTP (SSH File Transfer Protocol) to the
1694 lib/silcsftp. It includes SFTP client and SFTP server
1697 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1699 * Moved lib/silccore/silcprotocol.[ch] to the
1700 lib/silcutil library.
1702 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1703 take variable argument list pointer as argument. Affected
1704 file lib/silcutil/silcbuffmt.[ch].
1706 * Added silc_buffer_set function that is used to set data
1707 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1708 Affected file lib/silcutil/silcbuffer.h.
1710 * Changed various routines in the core library to use the new
1711 silc_buffer_set instead of allocating new buffer only for
1714 * Added 64-bit value formatting and unformatting support to the
1715 silc_buffer_[un]format routines. Affected file is
1716 lib/silcutil/silcbuffmt.[ch].
1718 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1719 to includes/bitmove.h.
1721 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1723 * Fixed channel user mode saving in client library. Affected
1724 file lib/silcclient/command[_reply].c.
1726 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1728 * Defined the file transfer to the SILC Protocol. Added
1729 new packet type SILC_PACKET_FTP and defined File Transfer
1730 Payload. The mandatory file transfer protocol is SFTP
1731 (SSH File Transfer Protocol). Affected file in addition
1732 of the internet draft is lib/silccore/silcpacket.h.
1734 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1735 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1736 is used as part of backup router protocol when the primary
1737 router of the cell is back online and wishes to resume
1738 the position as primary router.
1740 * Redefined the MAC generation keys in the protocol. The
1741 same key is not used anymore in both direction. Both
1742 direction will now use different keys for sending and
1743 receiving. This fixes a potential security flaw. This
1744 change causes incompatibilities in the protocol.
1746 * Redefined also the MAC computation from the packet.
1747 An packet sequence number is now added to the MAC
1748 computation. This prevents possible replay attacks against
1749 the protocol. This change too causes incompatibilities
1752 Added `sequence' field to the SilcPacketContext to hold
1753 the current sequence number for the packet.
1755 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1757 * Added `created' field to the SilcIDListData in the file
1758 silcd/idlist.h to indicate the time when the entry was
1761 * Added `created' field to the SilcChannelEntry too. Affected
1762 file silcd/idlist.h.
1764 * Added `creation_time' aguments to all the announcement functions
1765 in the server. If it is provided then only the entries that
1766 was created after the provided time frame are actually
1767 announced. Affected file silcd/server.[ch].
1769 * The protocol says that the Channel ID's IP address must be
1770 based on the router's IP address. Added check for this in
1771 the silc_server_new_channel when processing incoming New Channel
1772 Payload. Affected file silcd/packet_receive.c.
1774 * Print out the correct version with --version in SILC client.
1775 Affected file irssi/src/silc/core/silc-core.c.
1777 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1779 * Fixed WHOWAS command to check for completnes of the client
1780 entry always, not just when the command is coming from client.
1781 Affected file silcd/command.c.
1783 * Added new function silc_server_packet_queue_purge to purge the
1784 outgoing data queue to the network. After the function returns
1785 it is guaranteed that the outgoing packet queue is empty.
1786 Affected file silcd/packet_send.[ch].
1788 * Purge the outgoing packet queue in the rekey protocol's final
1789 callback to assure that all rekey packets go to the network
1790 before quitting the protocol. Affected file silcd/server.c.
1792 * Added silc_client_packet_queue_parse as similar function as
1793 in server to the client library. The affected file is
1794 lib/silcclient/client.c.
1796 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1798 * Splitted silcd/server.c and created silcd/server_util.[ch]
1799 for utility functions.
1801 * Added new socket flag SILC_SF_DISABLED to indicate that the
1802 connection is open but nothing can be sent to or received from
1803 the connection. Affected file lib/silcutil/silsockconn.[ch].
1804 The checking for disabled socket is checked in the low level
1805 silc_socket_write and silc_socket_read functions.
1807 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1809 * Allow only nicknames and channel names that fits into the
1810 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1812 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1814 * When processing JOIN command reply in server check that if
1815 the channel exists in our global list we'll move it the local
1816 list. Affected file silcd/command_reply.c.
1818 * Fixed the check whether client is joined on the channel already
1819 in JOIN command. Affected file lib/silcclient/command.c.
1821 * Fixed the JOIN command reply to check whether the channel
1822 already exists. Affected file lib/silcclient/command_reply.c.
1824 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1826 * Added silc_ske_status_string to map the SKE error numbers
1827 to readable strings. The affected files are
1828 lib/silcske/silcske[_status].[ch].
1830 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1832 * Do not show the private channels on the WHOIS channel list
1833 as it is not allowed by the protocol. The affected file is
1836 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1838 * Assure that the packet length digged from the actual packet
1839 is something sensible in the silc_packet_decrypt_rest_special
1840 in lib/silccrypt/silcpacket.c.
1842 * Free and NULL the allocated pointer in silc_hmac_alloc if
1843 the HMAC allocation fails. The affected file is
1844 lib/silccrypt/silchmac.c.
1846 * Print the selected security properties to the log files in
1847 the server. Affected file silcd/protocol.c.
1849 * Add SKE's reference counter even if calling the completion
1850 callback manually. Otherwise it goes negative, although it
1851 does not cause any problems. The affected file is
1852 lib/silcske/silcske.c.
1854 * Remove the client entry with short timeout after giving the
1855 KILL command. Affected file lib/silcclient/command.c.
1857 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1858 case all found clients are already disconnected (WHOWAS would
1859 found them) in the server. Affected file silcd/command.c.
1861 * Update the last_receive (time of last data received) to be
1862 updated only when received private or channel message so that
1863 the idle time showed in WHOIS makes more sense.
1865 * Added boolean field `valid' in to the SilcClientEntry in the
1866 client library to indicate whether the entry is valid or not.
1867 This fixes the nickname change bug on channel when changing
1868 the nickname to be same than the old (like nick to Nick) the
1869 nickname formatter doesn't set the new nick anymore to Nick@host.
1870 Affected file lib/silcclient/idlist.[ch].
1872 * Now actually fixed the nickname changing on disconnection.
1873 Added new function silc_change_nick to the Irssi SILC Client.
1874 Affected file irssi/src/silc/core/client_ops.c,
1875 irssi/src/silc/core/silc-nicklist.[ch].
1877 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1879 * Check that the public key exists in the GETKEY command before
1880 trying to encode it. Affected file silcd/command.c.
1882 * Print some notifications on received public keys with GETKEY
1883 command in the Irssi SILC Client. Affected files are
1884 irssi/src/fe-common/silc/module-formats.[ch],
1885 irssi/src/silc/core/client_ops.c.
1887 * Use IDENTIFY command to resolve the server information in the
1888 GETKEY command instead of INFO command. Affected file
1889 lib/silcclient/command.c.
1891 * All command reply functions in the client library now calls
1892 the pending command reply callbacks even if an error has
1893 occurred. The server has done this a long time and now it was
1894 time to move the client library to this as well. Now all
1895 errors can be delivered back to the pending command reply
1896 callbacks if necessary. Affected files are
1897 lib/silcclient/command[_reply].[ch].
1899 * Change the nickname on disconnection back to the username
1900 because in reconnect the server will enforce it to it anyway.
1901 Affected file irssi/src/silc/core/silc-servers.c.
1903 * Fixed a config file parsing bug in the Irssi SILC client.
1904 Affected file irssi/src/silc/core/clientconfig.c.
1906 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1908 * When printing the channel mode on JOIN, verify that the
1909 channel key and channel's HMAC are valid. Affected file
1910 irssi/src/silc/core/client_ops.c.
1912 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1914 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1915 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1916 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1918 * Removed channel key rekey task deleting from the function
1919 silc_server_save_channel_key. Affected file silcd/server.c.
1920 Added explicit timeout task context instead that is used to
1921 delete the task if we are registering a new task before the
1922 new task has elapsed.
1924 * When channel key rekey occurs the client library now saves
1925 the old channel key for a short period of time (10 seconds) and
1926 is able to use it in case some is still sending channel
1927 messages encrypted with the old key after the rekey. Affected
1928 file lib/silcclient/[idlist.h|client_channel.c].
1930 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1932 * Added check to the silc_server_new_id_real to not accept
1933 new ID if it is the sender's own ID. Affected file is
1934 silcd/packet_receive.c.
1936 * Assure that we do not announce ourself or the one we've
1937 sending our announcements when we're router and are announcing
1938 servers to our primary router. Affected file silcd/server.c.
1940 * Fixed silc_server_command_identify_check_client to assemble
1941 correct WHOIS packet. It send corrupted WHOIS packet and
1942 caused problem with router to router connections. Affected
1943 file silcd/command.c.
1945 Fixed also silc_server_command_whois_check the same way
1946 as for the IDENTIFY command.
1948 * Added new SilcIDListStatus to the server in the SilcIDListData
1949 structure. The status now includes the current status of
1950 the entry (like registered, resolved etc.). Affected file
1951 silcd/idlist.[ch]. Defined a bunch of different status types
1952 as well. This replaced the old boolean registered field as well.
1954 Added resolve_cmd_ident field to the SilcClientEntry structure
1955 too so that if the entry is for example being resolved so
1956 another command may attach to the same pending command reply
1957 without requiring to resolve the same entry again. This concept
1958 should optimize the WHOIS and the IDENTIFY resolving under
1959 heavy load by taking away unnecessary resolving for entries
1960 that are being resolved already.
1962 Added support for adding multiple pending commands for one
1963 command idenfier. Affected file silcd/command[_reply].[ch].
1965 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1966 before deleting the data. Otherwise the hash table will have
1967 freed data in comparison functions. Affected file is
1968 silcd/command_reply.c.
1970 * Fixed silc_idlist_replace_client_id to add the new entry to
1971 the cache with NULL nickname. Otherwise there will be invalid
1972 memory as the nickname after the nickname is freed. Affected
1973 file silcd/packet_receive.c.
1975 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1976 saved into wrong slots because the previous number of entries
1977 was not taken into account. Affected file silcd/idlist.c.
1978 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1980 * If we are router and we receive JOIN notify to a channel that
1981 does not have any users then notified client is marked as the
1982 channel founder, as it is it. The affected file is
1983 silcd/packet_receive.c
1985 * Added to the extended hash table API's table_del_*ext functions
1986 the destructor as argument too, so that the caller can decide
1987 which destructor to use or whether to use destructor at all.
1988 Affected file lib/silcutil/silchashtable.[ch].
1990 * Fixed ID Cache purging. It actually deleted the entries from
1991 the hash table after the data was freed. The hash table ended
1992 up comparing freed memory. The affected file is
1993 lib/silccore/silcidcache.c.
1995 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1997 * Fixed Irssi SILC client's KILL command's HELP syntax.
1999 * The USERS command now resolves the detailed user information
2000 if the userinfo field is missing. Affected file is
2001 lib/silcclient/command_reply.c.
2003 * Do not print error in silc_file_read if the read file does
2004 not exist. Just silently return NULL. Affected file is
2005 lib/silcutil/silcutil.c.
2007 * Fixed the silc_log_output to not wine about NULL filename
2008 and to not create some bogus " " filename. Affected file is
2009 lib/silcutil/silclog.c.
2011 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2013 * Fixed various printing bugs on the user interface in the
2014 Irssi SILC Client. Minor changes that were forgotten from
2017 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2019 * Fixed the configure.in.pre and the compilation and distribution
2020 environment to support the new autoconf 2.52. That version is
2021 now required to compile the CVS trunk.
2023 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2025 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2026 to generally parse user@fqdn format strings. Affected file
2027 lib/silcutil/silcutil.c.
2029 * Added nickname_format and nickname_force_format fields to the
2030 SilcClientParams structure. The first one defines the format
2031 for the nicknames that the library will enforce if the receives
2032 multiple same nicknames. The second one is boolean value and
2033 can be used to force the library to always enforce the format
2034 to the nicknames regardles whether there are multiple nicknames
2035 or not. This configurable formatting was employed to flexibly
2036 support accessing multiple nicknames from the user interface.
2037 The userinterface can now set the nicknames to what ever format
2038 they prefer. Affected file lib/silcclient/silcapi.h.
2040 Added function silc_client_nickname_format to the file
2041 lib/silcclient/idlist.c. It performs the nickname formatting.
2043 Added new field `hostname´ to the SilcClientEntry context.
2044 It holds the hostname of the client. Affected file is
2045 lib/silcclient/idlist.h.
2047 * Irssi SILC Client sets the nicknames in nick@hostn format.
2048 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2049 irssi/src/silc/core/silc-core.c.
2051 The WHOIS printing now also shows both the real nickname and
2052 the formatted nickname so that user knows how to access the
2053 user if there are multiple same nicknames cached. Affected
2054 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2055 printing formatting too to take the hostname now as a separate
2056 argument. The Affected file is
2057 irssi/src/fe-common/silc/modules-formats.[ch].
2059 * Changed the silc_client_get_clients_local to accept the formatted
2060 nickname as argument. It accepts the real nickname too but the
2061 formatted nickname can be used to find the true entry from
2062 multiple entries. Affected file lib/silcclient/silcapi.h and
2063 lib/silcclient/idlist.c.
2065 * Added nickname_format_parse field to the SilcClientParams.
2066 It is a callback function provided by the application to parse
2067 the nickname out of the formatted nickname string. The library
2068 calls it to get the nickname from the formatted string. Since
2069 the application generally knows better the format of the nickname
2070 string it parses it instead of the library, even though library
2071 encodes the formatted string. If the callback function is not
2072 provided then the library will use the string as is. The
2073 affected file is lib/silcclient/silcapi.h.
2075 * All the nickname strings passed to the client library in
2076 commands are now expected to be formatted nickname strings.
2077 If the command does not support the formatted nickname string
2078 it will assume that the sent string is the actual nickname.
2079 Affected file lib/silcclient/command.c.
2081 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2083 * Added public key authentication support to OPER and SILCOPER
2084 commands in the client library. Affected file is
2085 lib/silcclient/command.c.
2087 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2089 * Changed the get_auth_methdod client operation to be asynchronous.
2090 It can be async if the application resolves the authentication
2091 method from the server during the negotiation. Added new
2092 SilcGetAuthMeth completion callback that the application will
2093 call after resolving the authentication method.
2095 Added function silc_client_request_authentication_method that
2096 the application can use to resolve the authentication method
2097 from the server. Added also SilcConnectionAuthRequest callback
2098 that the library will call after the server has replied. The
2099 application can call this function if it does not know the
2100 current authentication method.
2102 Affected files are lib/silcclient/client.c and
2103 lib/silcclient/silcapi.h.
2105 * The Irssi SILC client now automatically resolves the authentication
2106 method incase any configuration information is not present (and
2107 currently there never is). The affected file is
2108 irssi/src/silc/core/client_ops.c.
2110 * Fixed public key authentication from the client library.
2111 Affected file lib/silcclient/protocol.c. Changed also the
2112 protocol specification about the public key authentication in
2113 the connection authentication protocol. The actual data to be
2114 signed is now computed with a hash function before signing.
2116 * Fixed the public key authentication from the server as well.
2117 Affected file silcd/protocol.c.
2119 * Removed the mlock()'s from the memory allocation routines.
2120 Affected file lib/silcutil/silcmemory.c. The ./configure does
2121 not check anymore for the mlock(). Affected file is
2124 * Fixed USERS command in server to allow the execution of the
2125 command for private and secret channels if the client sending
2126 the command is on the channel. Affected file silcd/command.c.
2128 * Fixed silc_client_get_clients_local to return the clients
2129 count correctly. It could return wrong value. Affected file
2130 lib/silcclient/idlist.c.
2132 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2134 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2135 types. The assembler optimizations seemed not to like 64-bit
2136 data types. The assmebler optimizations thus are now enabled
2137 also for BSD systems as opposed to only enable them for Linux.
2139 * Do not check for threads at all on BSD systems. Affected
2140 file configure.in.pre.
2142 * Removed -n and -h options from the Irssi SILC Client since
2143 they are not used in silc.
2145 * Fixed the prime generation to assure that the first digit
2146 of the generated random number is not zero since our conversion
2147 routines does not like number strings that starts with zero
2148 digit. If zero digit is seen the random number is regenerated.
2149 This caused some corrupted RSA keys when the zero first digit
2150 was met. Affected file lib/silcmath/silcprimegen.c.
2152 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2154 * Fixed WIN32 configuration in the ./configure script.
2155 Fixed to include xti.h on environments that has it.
2156 Patches by Carsten Ilchmann and andrew.
2158 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2160 * Changed the silc_id_create_client_id to be collision
2161 resistant. It is now assured that there cannot be created
2162 two same client ID's. I suspect that some weird bugs in
2163 the server were actually caused by duplicate Client IDs.
2164 Affected file silcd/serverid.[ch]. A router receiving
2165 new ID now also assures and informs the sending server
2166 if the ID caused collision.
2168 * Changed the silc_id_create_channel_id to also assure that
2169 there are no collisions.
2171 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2173 * Statement about ignoring the Mutual Authentication flag when
2174 performing rekey with PFS was a bit misleading. It is ignored
2175 if it was set in the initial negotiation, it cannot be even
2176 set in the rekey. Fixed in the ke-auth draft. Started the
2177 new versions of the protocol drafts in the doc/.
2179 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2181 * Fixed a bug in silc_client_command_identify_save when saving
2182 new channel information. The channel name was no duplicated
2183 and caused crash on exit. Affected file is
2184 lib/silcclient/command_reply.c.
2186 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2188 * Fixed the getkey command handling in the server. Send just
2189 empty OK reply to the sender if the key could not be fetched
2190 (but everything else was ok, like the key just was not available).
2191 Changed the public key parameter to optional in the protocol
2192 specs so that empty OK reply can be sent. Affected file
2195 Added a message to Irssi SILC client to tell to user if the
2196 server did not return a public key.
2198 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2200 * Fixed a channel key regeneration bug. It registered new
2201 timeout tasks exponentially until all system resources were
2202 used. Affected file silcd/server.c.
2204 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2206 * Added the SILC Document generator to the scripts/silcdoc.
2207 It can be used to generate the Toolkit Reference Manual out
2208 of the source tree. Internally it will also use the RoboDoc
2209 generator now imported in util/robodoc.
2211 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2213 * Added couple of return's in rekey protocol if error orccurred
2214 during the protocol. The execution must be terminated.
2215 Affected file silcd/protocol.c. Also, terminate the protocol
2216 always with timeout.
2218 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2220 * The client's Client ID was created initally from the wrong
2221 nickname (it could have been in format nick@host) in the
2222 silc_server_new_client. Affected file silcd/packet_receive.c
2224 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2226 * Added some SILC_LOG_ERROR's to various error conditions
2227 if client could not be added to ID cache. Affected files
2228 silcd/packet_receive.c and silcd/server.c.
2230 * When client's sock->user_data is freed, NULL also the
2231 client->router and client->connection pointers. Added check
2232 for these pointers being NULL to various places around the
2233 code. Affected file silcd/server.c.
2235 * Added client->data.registered == TRUE checks to various
2236 places around the code to assure that unregistered client's
2237 are not handled when it is not allowed. Affected file
2240 * Added `bool registered' fields to all
2241 silc_idlist_[server|client]_get_* routines to indicate whether
2242 the fetched client needs to be registered or not. Affected
2243 file silcd/idlist.[ch].
2245 * Add your own entry as registered to the ID cache in the
2246 server. Affected file server.c.
2248 * Fixed a bug in silc_server_new_server. The SilcServer was
2249 set as the new server's context instead of SilcServerEntry.
2250 This naturally caused some weird bugs.
2252 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2254 * Do not delete the channel rekey task when adding it
2255 for in silc_server_create_channel_key.
2257 * Changed the silc_server_create_channel_key to return
2258 TRUE or FALSE to indicate the success of the channel key
2261 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2263 * Fixed MSVC++ project files and added missing files to
2264 Makefiles under win32/.
2266 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2268 * Do not add TCP_NODELAY flag if the operating system
2269 does not have it defined. Affected files are
2270 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2272 * Fixed buffer overflow from Irssi SILC Client. Affected
2273 file irssi/src/fe-common/core/themes.c.
2275 * Fixed double free in client library in the file
2276 lib/silcclient/client.c when disconnecting from server.
2278 * Applied double free patch from cras to Irssi SILC client.
2279 Affected files irssi/src/core/[modules/expandos].c
2281 * Fixed the disconnection handling to Irssi SILC Client.
2282 The application must call silc_client_close_connection
2283 in ops->connect client operation in case of failure of
2284 the connection. Affected file is
2285 irssi/src/silc/core/client_ops.c.
2287 * Do not set sock->protocol to NULL in the function
2288 silc_client_close_connection after executing the protocol's
2289 final callback since the sock might not be valid anymore.
2290 Affected file lib/silcclient/client.c.
2292 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2294 * Do not enable SILC_THREADS if the linking with libpthread
2295 did not happen. Affected file configure.in.pre.
2297 * Added notion to protocol specification that server must
2298 verify the sent authentication payload with CMODE when
2299 setting the channel founder key. Implemented it to the
2300 server. Affected file silcd/command.c.
2302 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2304 * Added _EXTRA_DIST SILC distribution variable to the
2305 distributions file. It is used to conditionally add extra
2306 files or directories to the specific distribution. Affected
2307 files ./prepare, Makefile.am.pre and distributions.
2309 Removed the `_' from the start of the distribution names.
2312 * Added README.WIN32 for instructions to compile the Toolkit
2315 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2317 * Fixed a double free in disconnection in the server. Affected
2318 file is silcd/server.c.
2320 * Fixed the lib/silcske/groups.c to work now also with GMP
2321 MP library. The string conversion did not work when using
2322 specific base and the base is indicated in the string as well.
2324 * Created win32/ directory which now includes MSVC++ specific
2325 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2326 It will appear only in the toolkit distribution
2328 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2330 * Changed the key material distribution function in case when
2331 the hash output is too short. The data is now concatenated
2332 a bit differently than it used to. Made the change to the
2333 SKE protocol specification.
2335 * Added better GMP detection to configure.in.pre. A patch
2338 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2340 * Fixed a minor bug in SKE that might cause some problem on
2341 some platforms. Affected file lib/silcske/silcske.c.
2343 * Added the cookie checking for initiator in the SKE. It checks
2344 that the responder returns the sent cookie unmodified. The
2345 affected file is lib/silcske/silcske.c. Added new SKE
2346 error type INVALID_COOKIE that can be sent during the
2347 negotiation. Fixed some memory leaks as well.
2349 * Added the "invalid cookie" error message to Irssi SILC client's
2352 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2354 * Added `task_max' field to the SilcClientParams to indicate
2355 the maximum tasks the scheduler can handle. If set to zero,
2356 default values are used. Affected file lib/silcclient/silcapi.h.
2358 * Fixed memory leaks in silc_client_close_connection. Affected
2359 file lib/silcclient/client.c.
2361 * Added silc_client_del_client_entry to client library to free
2362 all memory of given client entry. Affected file is
2363 lib/silcclient/idlist.[ch].
2365 * Added new functions silc_client_del_channel and
2366 silc_client_del_server to delete channel and server entries.
2367 Affected file lib/silcclient/[silcapi.h/idlist.c].
2369 * Removed silc_client_del_client_by_id from silcapi.h.
2371 * Fixed the INFO command to return the server's own info
2372 correctly when querying by Server ID. Affected file is
2375 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2377 * Removed the non-blocking settings in WIN32 code in the
2378 silc_sock_[read/write] and added SleepEx instead. Affected
2379 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2380 of input data is now checked with FIONREAD and ioctlsocket.
2382 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2384 * Call silc_schedule_task_del_by_context in the
2385 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2386 Affected file lib/silccore/silcprotocol.c.
2388 * Call silc_protocol_cancel for active protocols in the
2389 silc_server_close_connection if the funtion
2390 silc_server_free_sock_user_data has not been called.
2391 Affected file silcd/server.c.
2393 * Generic tasks cannot be deleted using the del_by_fd
2394 task deleting function since generic tasks does not match
2395 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2397 * Added a notion to SILCOPER help file that the SILCOPER works
2398 only on router server, not on normal server.
2400 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2402 * Added for WIN32 support for the new scheduler as well.
2403 Affected file lib/silcutil/win32/silcwin32schedule.c.
2405 * Fixed the SHA1 implementation to work on various platforms.
2407 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2409 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2410 API. It is part of the scheduler now. Everything else is
2411 as previously but some functions has changed their names.
2412 Checkout the lib/silcutil/silcschedule.h for the interface.
2413 Updated all applications to use the new interface. Affected
2414 files are lib/silcutil/silcschedule.[ch].
2416 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2418 * Found a bug in the SKE implementation. The HASH value,
2419 specified by the protocol, was not computed correctly. The
2420 public key of the responder was not added to the computation
2421 even though it is mandatory. Affected file lib/silcske/silcske.c.
2422 This unfortunately causes incompatibilities with older
2423 clients and servers.
2425 * Added WIN32 specific network init and uninit functions:
2426 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2427 the Winsock2. Affected file lib/silcutil/silcnet.h and
2428 lib/silcutil/win32/silcwin32net.c.
2430 * Set the socket always to nonblocking mode on WIN32 after
2431 reading data or writing data. Affected file is
2432 lib/silcutil/win32/silcwin32sockconn.c.
2434 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2436 * Fixed various compilation problems under WIN32. Affected
2437 files lib/silcutil/win32/silcwin32thread.c and
2438 lib/silcutil/win32/silcwin32schedule.c.
2440 * Removed all _internal.h #includes from public header
2441 files. Internal headers must never be included from
2444 Removed also the lib/silcske/payload_internal.h file.
2446 * All include files that may be needed (public and some others
2447 included by the public headers) by application developers are
2448 now copied to the ./includes directory. It does not copy any
2449 internal headers. Affected file Makefile.defines.pre and all
2450 Makefile.am's under lib/ and subdirs.
2452 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2454 * Do not change the ~/.silc directory's permissions automatically.
2455 Affected file irssi/src/silc/core/clientutil.c.
2457 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2459 * Do not cancel the protocol in silc_server_close_connection
2460 it might cause recursion. Now cancelled in the function
2461 silc_server_free_sock_user_data. Affected file silcd/server.c.
2463 * Fixed the silc_server_remove_clients_by_server to regenerate
2464 the channel keys correctly finally. Added also new function
2465 silc_server_remove_clients_channels to actually do it.
2466 Affected file silcd/server.c.
2468 * Fixed the silc_server_new_channel to not crash by giving
2469 wrong router to the new channel. Affected file is
2470 silcd/packet_receive.c.
2472 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2474 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2475 which is given as argument to the silc_client_alloc now.
2476 It can be used to configure the client and set various parameters
2477 that affect the function of the client.
2479 * The USERS command in server did not check whether the channel
2480 is private or secret. Affected file silcd/command.c.
2482 * Added new argument to the USERS command in protocol specification.
2483 The USERS command now can take the channel name as argument
2484 as well. Added support for this in client and server and
2485 updated the protocol specs.
2487 * Completed the GETKEY command in client. It can be now used
2488 to fetch also servers public key not only some clients.
2489 Affected files lib/silcclient/command[_reply].c.
2491 * Added silc_client_get_server to return server entry by the
2492 server name. Affected files lib/silcclient/silcapi.h and
2495 * Redefined the IDENTIFY command in protocol specification to be
2496 more generic. It now can be used to query information about
2497 any entity in the SILC Network, including clients, servers and
2498 channels. The query may be based either the entity's name
2499 or the ID. Added support for this in both client and server.
2501 Affected files silcd/command.c and lib/silcclient/command.c
2502 and command_reply.c.
2504 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2505 the _from_client and _from_server functions. Affected file
2508 * Added silc_client_get_channel_by_id_resolve to the file
2509 lib/silcclient/silcapi.h to resolve channel information by
2510 its ID. Added also silc_client_get_channel_by_id that
2511 does not resolve it from the server.
2513 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2515 * Added SilcServerEntry context into the client library
2516 to represent one server. The INFO command now allocates
2517 these to save the resolved server info. For now on the
2518 client library will also keep information about servers,
2519 connected and resolved with INFO.
2521 The INFO command now allocates the SilcServerEntry context
2522 and saves the server info there. The COMMAND_REPLY in
2523 the INFO now returns the parameters to application in
2524 same order as defined in the protocol specification.
2526 The entries are cached in the client->server_cache.
2528 * The INFO command is now issued after received the Client ID
2529 from the server. Affected file lib/silcclient/client.c.
2531 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2532 to the application as the mode changer might be server.
2533 It is guaranteed that NULL is not returned anymore to the
2534 application. Affected file lib/silcclient/client_notify.c.
2536 The ID Type is now also passed to the application so that
2537 it can check whether the returned entry is SilcClientEntry
2540 Added new function silc_client_get_server_by_id to return
2541 the server entry by ID. Affected files are the
2542 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2544 * Do not create the channel in the Irssi SILC Client when issuing
2545 the JOIN command but when received the sucessful JOIN command
2546 reply. Otherwise the channel might get created even though we
2547 could not join it. The Affected file is
2548 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2550 * Fixed a channel joining bug in router. The router must also
2551 check the channel modes, invite and ban lists etc. when serving
2552 the JOIN command sent by normal server. Affected file is
2553 silcd/command.c. The router now resolves the client's
2554 information from the server who sent the JOIN command if it
2555 does not know it, and processes the JOIN command only after
2558 * Changed the SilcCommandCb to take new argument; void *context2.
2559 Affected file lib/silccore/silccommand.h
2561 The second argument in the command callbacks in the server now
2562 includes the SilcServerCommandReplyContext if the command was
2563 called as pending command callback from the command reply.
2564 Otherwise it is NULL. When called as pending the status of the
2565 command reply will be checked and if it was erronous the
2566 error will be sent to the original sender of the command.
2567 This way the client always receives the error messages even
2568 though the server was actually the one who received the error
2569 when it resent the command to router, for example. Affected
2570 files silcd/command[_reply].[ch].
2572 * Fixed sending WHOWAS command's error message to client if
2573 the requested client could not be found. It was missing.
2576 * Changed the CMODE and CUMODE commands reply arguments in the
2577 protocol specification. The Channel ID is now sent in both
2578 of the commands to identify the channel. Implemented this
2579 new feature to the client and server. Affected files
2580 lib/silcclient/command_reply.c and silcd/command.c.
2582 * Made better checks for invite and ban lists in the JOIN
2583 command in server. Affected file silcd/command.c.
2585 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2587 * The server now performs the incoming host IP/DNS lookup
2588 using the silc_socket_host_lookup and thus does not block
2589 the server anymore. Affected file silcd/server.c.
2591 * Completed the multi-thread support for SILC Scheduler in
2592 the lib/silcutil/silcschedule.c.
2594 * Fixed the configure.in.pre to detect the pthread correctly
2597 * Fixed a deadlock in silc_task_queue_wakeup in the file
2598 lib/silcutil/silctask.c.
2600 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2602 * Added new function silc_schedule_wakeup that is used in
2603 multi-threaded environment to wakeup the main thread's
2604 schduler. It needs to be used when a thread adds a new task
2605 or removes a task from task queues. After waking up, the
2606 scheduler will detect the task queue changes. If threads
2607 support is not compiled in this function has no effect.
2608 Implemented the wakeup mechanism to both Unix and WIN32
2609 systems. Affected files are lib/silcutil/silcschedule.[ch],
2610 lib/silcutil/unix/silcunixschedule.c and the
2611 lib/silcutil/win32/silcwin32schedule.c.
2613 * Added new function silc_task_queue_wakeup to wakeup the
2614 scheduler by the specified task queue. Affected file
2615 lib/silcutil/silctask.[ch].
2617 * The silc_socket_host_lookup_start now wakes up the scheduler
2618 after adding the timeout task. Affected file is
2619 lib/silcutil/silcsockconn.c.
2621 * The silc_socket_host_lookup is synchronous now if the threads
2622 support is not compiled in. However, the callback is still
2623 called asyncronously through the scheduler, anyway. Affected
2624 file lib/silcutil/silcsockconn.c.
2626 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2628 * Added new function silc_socket_host_lookup to perform
2629 asynchronous IP and FQDN lookups for the socket connection.
2630 Affected files lib/silcutil/silcsockconn.[ch].
2632 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2634 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2635 that may or may not compile the mutex support in.
2637 Changed the silc_mutex_alloc interface. It allocates the
2638 mutex now to the sent pointer and returns TRUE or FALSE.
2640 Affected file lib/silcutil/silcmutex.h.
2642 * Wrote the SILC Task Queue interface to support multi-threads.
2643 Affected file lib/silcutil/silctask.[ch].
2645 * Wrote the SILC Scheduler to support multi-threads. Affected
2646 file lib/silcutil/silcschedule.c.
2648 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2650 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2651 in lib/silcutil/win32/.
2653 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2655 * Defined SILC Mutex API and SILC Thread API and implemented
2656 them for Unix. Affected files are
2657 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2658 lib/silcutil/unix/silcunixmutex.c and
2659 lib/silcutil/unix/silcunixthread.c.
2661 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2663 * Fixed the silc_server_remove_clients_by_server's channel
2664 key re-generation. The hash table handling was incorrect
2665 and would not work with many channels. Affected file is
2668 * Fixed some memory leaks around the server code.
2670 * Rewrote the silc_server_get_users_on_channel to support IPv6
2671 based Client ID's. Affected file silcd/server.c.
2673 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2674 specification. However, a separate document must be written
2675 to define the detailed signing procedure and the payload
2676 associated with the flag. Defined the flag to the
2677 lib/silccore/silcchannel.h as well.
2679 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2681 * Changed the dynamic tables to static size tables in the
2682 lib/silccrypt/silchmac.c.
2684 * Removed GCC dependencies from the code. A patch by cras.
2686 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2688 * Do not show the error "Error receiving packet bla bla"
2689 in server if it really was not an error (-2 means that reading
2690 is pending). Affected file silcd/server.c.
2692 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2694 * Fixed a possible crash in silc_server_remove_clients_by_server
2695 in silcd/server.c. Fixed there also some memory leaks.
2697 * Fixed the silc_idlist_replace_client_id. It could replace
2698 wrong key in the hash table. Affected file silcd/idlist.c.
2700 * Do not check whether there are global users on the channel
2701 if the channel->global_users is FALSE. Affected functions
2702 silc_server_remove_from_one_channel and
2703 silc_server_remove_from_channels in silcd/server.c. Also,
2704 do not check if the removed client is local as we can be
2705 sure that global client was not removed from the channel
2706 and checking for global users is not needed.
2708 * The silc_server_remove_clients_by_server now re-generates
2709 the channel keys correctly for those channels that had
2710 clients removed from them. Affected file silcd/server.c.
2712 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2714 * Found the reason of random crashes in the server. We weren't
2715 ignoring the SIGPIPE signal (which can be sent in write())
2716 and it crashed the server. Affected file silcd/silcd.c.
2718 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2720 * Assure that sock->user_data is not NULL in the function
2721 silc_server_packet_send in silcd/packet_send.c.
2723 * Disconnect the remote connection if it could not be added
2724 to any ID lists in the server. The affected file is
2727 * Check in silc_server_packet_send[_real/dest] that the
2728 socket is not disconnecting and ignore the data if it is.
2729 Affected file silcd/packet_send.c.
2731 * Define inline to __inline on native WIN32 compilation.
2732 Affected file includes/silcwin32.h.
2734 * Added some explicit type casts for inline code since MSVC
2735 require them. Affected files lib/silcutil/silcbuffer.h,
2736 lib/trq/silcdlist.h and lib/trq/silclist.h.
2738 * Print warning in log files from now on if the packet
2739 decryption fails. Affected file silcd/server.c.
2741 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2743 * Changed the `say' client operation's interface to accept
2744 new `type' argument to indicate the type of the message sent
2745 by the library. The application may filter the library's
2746 messages according the type. The affected file is the
2747 lib/silcclient/silcapi.h.
2749 * Added two new functions to lib/silcclient/silcapi.h:
2750 silc_client_del_client and silc_client_del_client_by_id.
2751 Affected file lib/silcclient/idlist.c.
2753 * Moved the clientincludes.h from includes/ to silc/ and
2754 serverincludes.h from includes/ to silcd/.
2756 * The modes for the CMODE and CUMODE are now passed as
2757 uint32 for application with COMMAND_REPLY. The affected
2758 file is lib/silcclient/command_reply.c.
2760 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2762 * /WHOIS without arguments shows client's own information.
2763 Affected file lib/silcclient/command.c.
2765 * Changed PING to not accept any arguments. The specs
2766 says that client can ping only the connected server so
2767 requiring an argument is not needed. Affected file is
2768 lib/silcclient/command.c.
2770 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2772 * Fixed a fatal bug in private message sending and reception
2773 encryption and decryption when using private message keys.
2774 The implementation was incorrect and did not follow the
2775 specification. It causd that some of the message were
2776 lost since it did not use the sending and receiving keys
2777 as the protocol suggests. This has been fixed and will cause
2778 incompatibilities with older clients when sending private
2779 message encrypted with private message keys. Affected files
2780 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2781 and various other in Irssi SILC Client.
2783 Added `responder' boolean argument to the functions
2784 silc_client_add_private_message_key[_ske] to indicate when
2785 the key is added as responder or initiator of the key
2788 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2790 * Removed the silc_ske_check_version function and created
2791 a SilcSKECheckVersion callback. Added also a function
2792 silc_ske_set_callbacks that is now used to set all SKE
2793 callbacks. The callback functions are not given to
2794 the SKE functions anymore, but this function is used to
2797 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2799 * Added `silc_version' argument to the silc_client_alloc
2800 to define the version of the application for the library.
2801 The library will use the version string to compare it
2802 against the remote host's (usually a server) version
2803 string. Affected file lib/silcclient/silcapi.h
2805 * Added the KE protocol context to Key Agreement context
2806 in client library so that we can abort the SKE if it
2807 is in process when we get timeout. Affected file is
2808 lib/silcclient/client_keyagr.c.
2810 * Do not resolve the client ID forever if it returns in the
2811 first time that such client does not exist. This was done
2812 for example with private message. Affected file is
2813 lib/silcclient/client_prvmsg.c.
2815 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2817 * Do not add regex.h for WIN32. The affected file
2818 includes/silcincludes.h.
2820 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2821 not work yet 100%. It generates the DLL's automatically
2822 when compiling with --with-win32 under cygwin.
2824 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2826 * lib/contrib/regex.c is not compiled on WIN32.
2828 * Added silc_net_get_socket_opt function to the
2829 lib/silcutil/silcnet.h.
2831 * Added includes/silcwin32.h for WIN32 specific includes
2834 * Do not use ptime structure or any of the posix process
2835 functions on WIN32 in lib/silccrypt/silrng.c.
2837 * Added silc_gettimeofday to provide generic function
2838 for struct timeval on all platforms. Added the function
2839 to lib/silcutil/silcutil.h.
2841 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2843 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2844 library as they clearly belong there. As a plus side we
2845 can make the actual socket connection routines platform
2848 Added also new generic function silc_socket_read and
2849 silc_socket_write (that used to be silc_packet_[read/write].
2850 The implementation of these are platform specific.
2852 * Added WIN32 specific routines of silc_socket_[read/write]
2853 to lib/silcutil/win32/silcwin32sockconn.c.
2855 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2857 * Added preliminary support for native WIN32 compilation under
2858 cygwin (using the -mno-cygwin option for GCC) to the
2859 ./configure.in.pre. The --with-win32 now prepares the
2860 compilation for native WIN32.
2862 * Rewrote the SILC Scheduler interface in the file
2863 lib/silcutil/silcschedule.h. The scheduler is now context
2864 based and does not have anymore any global static scheduler.
2865 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2866 and created lib/silcutil/win32 directory for WIN32 based
2869 * Added Unix specific network routines to the
2870 lib/silcutil/unix/silcunixnet.c and the old
2871 lib/silcutil/silcnet.c includes now only generic routines.
2873 Added WIN32 specific network routines to the
2874 lib/silcutil/win32/silcwin32net.c.
2876 * Added Unix specific utility functions from the
2877 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2879 * Added WIN32 SILC Scheduler to the file
2880 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2883 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2885 * Do not handle JOIN notify in the server if the target client
2886 is not registered (idata->registered == FALSE). The affected
2887 file is silcd/packet_receive.c.
2889 * Update the nickrec->founder in event_cumode in the Irssi SILC
2890 client. Affected file irssi/src/silc/core/silc-channels.c.
2892 * Fixed the CUMODE_CHANGE notify handling in the server when
2893 server and router are announcing their clients on channels.
2894 Now the mode changes are saved and notified correctly. The
2895 affected file is /silcd/packet_receive.c.
2897 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2898 They really did not replace the cache entry in the ID Cache.
2899 Now they do that. Affected file silcd/idlist.c.
2901 * Fixed the KICK notify handling in the Irssi SILC client to
2902 update the channel records so that the kicked client does not
2903 appear to be on the channel. The affected file is
2904 irssi/src/silc/core/silc-channels.c.
2906 * Always update the conn->current_channel when executing command
2907 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2909 * Fixed the KILL notify handling in Irssi SILC client to remove
2910 the killed client on all channels.
2912 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2914 * Fixed the silc_parse_command_line to remove extra spaces
2915 from the start and end of the arguments. Affected file is
2916 lib/silcutil/silcutil.c.
2918 * Cancel and free any active protocol in the function
2919 silc_server_close_connection. Affected file silcd/server.c.
2921 * Cancel and free any active protocol in the function
2922 silc_client_close_connction. Affected file is
2923 lib/silcclient/client.c.
2925 * Do not execute the KILL command for clients that are in
2926 history (ie. they are not in the network). Affected file is
2929 * Fixed KILL notify handling, client does not crash anymore.
2930 Affected file irssi/src/silc/core/silc-channels.c.
2932 * Reduced the default packet buffer size from 2048 to 1024 in
2933 lib/silccore/silcpacket.c.
2935 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2936 counter to the SKE context that is incresed when the SKE library
2937 performs async operation outside the library. If the outside
2938 process frees the SKE context and FREED status will be set
2939 and the library will detect after the sync operation that the
2940 libary is freed. The affected files are
2941 lib/silcske/silcske[_status].[ch].
2943 * Resolve the client entry information in the function
2944 silc_client_channel_message to assure that NULL pointer is not
2945 passed as client entry to the application. */
2947 * Fixed the task timeout calculation to assure that there is
2948 never negative timeouts. The affected file is
2949 lib/silcutil/silcschedule.c.
2951 * Fixed the channel user mode notification sending in server.
2952 It was sent point-to-point to the router (or to server by router)
2953 but it needs to be destined to a channel. The routines now
2954 supports sending the channel user mode notifys to the channels
2955 when announcing clients and channels. Affected files are
2956 silcd/server.c and silcd/packet_receive.c.
2958 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2959 It did not actually replace the old channel entry in the cache.
2960 Affected file lib/silcclient/client_notify.c.
2962 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2964 * Fixed a possible crash in silc_packet_send_prepare. It now
2965 assures always that there is enough space in the buffer and
2966 at the tail area of the buffer (for MAC).
2968 Fixed the inbound buffer reallocation in silc_packet_read.
2969 It was old code and did not handle the reallocation correctly.
2972 The affected file is lib/silccore/silcpacket.c.
2974 * Fixed buffer overflow in silc_parse_nickname in the file
2975 lib/silcutil/silcutil.c.
2977 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2979 * make install generates new server keys only if there is not
2982 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2984 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2985 Added check that if the NOREPLY is set then we will not send
2986 the away message. This avoids infinite loop of away messages
2987 if both clients are away. The affected file is
2988 lib/silcclient/client_prvmsg.c.
2990 * Fixed client crash if /NICK was given without arguments.
2991 Affected file lib/silcclient/command.c.
2993 * Server does not send the invite list in INVITE command back
2994 to the client if the list was not altered. Added this notion
2995 to the protocol spec as well. Affected file silcd/command.c.
2997 Fixed possible crash in INVITE command by checking the
2998 value of silc_server_get_client_route command.
3000 * Fixed the INVITE notify type handling. The arguments are now
3001 taken in correct order and client does not crash. The affected
3002 file is irssi/src/silc/core/silc-channels.c.
3004 Removed the "Inviting xxx to channel" message from the
3005 client library away and let the application handle it.
3006 Affected file lib/silcclient/command.c. Added that message
3007 to Irssi SILC client's message formats.
3009 * Fixed CMODE command crash in client. It now checks the
3010 amount of arguments correctly and does not crash. The affected
3011 file is lib/silcclient/command.c.
3013 * Do not create new channel automatically in silc_channels_join
3014 but check whether the channel by that name already exists.
3015 Affected file irssi/silc/core/silc-channels.c.
3017 * Do not send the SERVER_SIGNOFF to router if the disconnected
3018 entity was the router. Affected file silcd/server.c.
3020 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3021 SILC client as it was missing from there.
3023 Added the handling of the KICK notify to the Irssi SILC client
3024 as it was missing. Added "you have been kicked" message to
3025 Irssi SILC client's message modules formats.
3027 Added the handing of the KILL notify to the Irssi SILC client
3028 as it was missing. Added the kill message module formats
3031 The affected file is irssi/src/silc/core/silc-channels.c.
3033 * The router did not save the channel mode the server announced.
3034 Affected file silcd/packet_receive.c.
3036 * Fixed a possible crash in INFO command in server. If the
3037 server did not provide the server info it crashed. Affected
3038 file silcd/command.c.
3040 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3042 * Fixed the GETKEY command in the server to check also the
3043 global list. Otherwise the GETKEY would not work correctly
3044 in normal SILC server. Affected file silcd/command.c.
3046 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3048 * Fixed GETKEY crash, it crashed if the command did not succseed.
3050 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3052 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3053 is now real and not just an macro interface to GMP.
3055 Removed the entire GMP from the source tree and imported new
3056 NSS MPI library instead. Reason for removing GMP is that it is
3057 extremely large and compiles extremely slow. The NSS MPI
3058 is only a few files and compiles in less than 10 seconds.
3059 The speed is also about the same as GMP. The MPI is imported
3060 to lib/silcmath/mpi.
3062 If the system has GMP installed we will still use the GMP.
3063 If it is not then the NSS MPI will be compiled.
3065 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3067 * Merged a long nickname (127 characters long) crash bugfix from
3068 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3070 * Merged a freed memory reference bugfix from Irssi CVS tree.
3071 Affected file irssi/src/core/commands.c.
3073 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3075 * Added the server's public key sving and verification to the
3076 server when performing the SKE. This was missing and the
3077 remote server's (or router's) public key was accepted without
3078 checking whether we have it previously or trust it at all.
3079 Affected file silcd/protocol.c.
3081 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Check in the silc_server_timeout_remote if protocol is active
3084 and make sure that the protocol's final callback is called so
3085 that all memory if freed. Affected file silcd/server.c.
3087 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3089 * silc_server_whois_send_reply crashed the server if the nickname
3090 was 127 characters long. Affected file silcd/command.c.
3092 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3094 * Added sanity check to the silc_server_new_client. If the hostname
3095 is provided inside username then check that the provided hostname
3096 really is the same as the resolved one. If the hostname was not
3097 resolved then check it from the public key. Affected file is
3098 silcd/packet_receive.c.
3100 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3101 if the server disconnected us and the connection is not valid
3102 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3104 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3105 the library to the lib/silcutil/silcutil.[ch].
3107 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3109 * Close log file after open. Affected file
3110 lib/silcutil/silclog.c.
3112 * Check whether sock == NULL in silc_client_send_packet and return
3113 if it is. Affected file lib/silcclient/silcclient.c.
3115 * Check rec->entry == NULL in the Irssi SILC Client before
3116 sending the channel message. Affecte file is
3117 irssi/src/silc/core/silc-servers.c.
3119 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3121 * Merged a splitted window bugfix from Irssi CVS tree. The
3122 affected file is irssi/src/fe-text/textbuffer-view.c.
3124 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3125 It did not print nickname.
3127 * Improved the distributions system a bit.
3129 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3131 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3132 irssi/src/fe-text/gui-window.c.
3134 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3135 to in-active server. The affected file is
3136 irssi/src/silc/core/client_ops.c.
3138 * Resolve the client in USERS command reply if the entry does
3139 not have username resolved. The affected file is
3140 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3141 command to WHOIS command to really resolve stuff. The USERS
3142 is not used any more in any critical section so WHOIS can
3143 be used even though it might be slower than IDENTIFY.
3145 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3148 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3150 * Changed the protocol API a bit more consistent in the
3151 lib/silccore/silcprotocol.[ch].
3153 * Changed the following headers to ROBODoc format:
3155 lib/silccore/silcpayload.h
3156 lib/silccore/silcprotocol.h
3157 lib/silccore/silcsockconn.h
3159 All core library headers are now formatted.
3161 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3163 * Fixed a bug in Irssi SILC client; do not show that you are
3164 server/router operator if you really are not. Affected file is
3165 irssi/src/silc/core/client_ops.c.
3167 * Renamed silc_command_free_payload to silc_command_payload_free.
3168 Affected file lib/silccore/silccommand.h
3170 * Added silcmath.h to include the prototoypes of various routines
3171 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3174 * Changed the following headers to ROBODoc format:
3176 lib/silccore/silcchannel.h
3177 lib/silccore/silccommand.h
3178 lib/silccore/silcid.h
3179 lib/silccore/silcidcache.h
3180 lib/silccore/silcmode.h
3181 lib/silccore/silcnotify.h
3182 lib/silccore/silcpacket.h
3183 lib/silcmath/silcmath.h
3185 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3187 * Added checking to the server code not to start the server if
3188 ciphers and stuff are not configured properly. Affected files
3189 silcd/serverconfig.[h] and silcd/server.c.
3191 * Changed the layout of the header files of the public interfaces
3192 in the SILC libraries. The new layout supports ROBODoc
3193 documentation tool (and some others) so that it is easy to create
3194 a library reference manual. All the other headers and source
3195 code must still follow the CodingStyle document. Also source
3196 code must not include these ROBODoc stuffs, only the headers.
3197 Furthermore, all public interface headers must now be named
3198 by using `silc' prefix, example: silcapi.h, silccipher.h.
3199 Some files were renamed due to this. All the other headers
3200 must not be used as public interfaces. I will update the
3201 CodingStyle document later. Changed following headers, so far:
3203 lib/silcclient/silcapi.h
3204 lib/silccore/silcauth.h
3205 lib/silccore/silcprivate.h
3206 lib/silccrypt/silcdh.h
3208 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3212 * Removed silc_client_packet_send_flush from the client library
3213 as it is not needed. Affected file lib/silcclient/client.[ch].
3215 * Added printing of message of unresolved authentication method
3216 to the Irssi SILC client. Added it to the module formats.
3217 Removed the same message from the client library.
3219 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3221 * Added new distribution feature, DISTLABEL. Every distribution
3222 can define own preprocessor label that can be used in the
3223 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3224 file distributions, acconfig.h.pre and prepare.
3226 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3228 * Added Makefile.defines_int to include the actual definitions
3229 for Makefile.defines.in. Tested the new distribution system,
3230 created distributions and tested installation.
3232 * Added AWAY message printing to the Irssi SILC client. Added
3233 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3235 * Added SCONNECT command to call the SILC's CONNECT command.
3236 Cannot use CONNECT directly since Irssi uses that internally.
3237 Affected file irssi/src/silc/core/silc-servers.c.
3239 Added ACTION local command. It is same as ME command but takes
3240 the channel as mandatory argument.
3242 Rewrote some of the Irssi's help files to suite for SILC
3245 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3247 * Added Makefile.defines[.in] that should for now on be included
3248 in all Makefile.am file in the source tree. That file includes
3249 all common compilation definitions for SILC source tree.
3251 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3253 * Minor changes to the ./prepare script to change the package
3254 name according the distribution name to the configure.in.
3256 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3258 * Created new distribution system. Added file `distributions'
3259 that defines all the distributions that can be created out of
3260 the SILC source tree. The ./prepare script now reads that
3261 file to determine how to prepare the distributions. The
3262 first argument to the ./prepare is the name of the distribution
3263 and second is the version of the distribution. If given
3264 without arguments it creates the default (toolkit) distribution
3265 with the default version (defined in ./prepare).
3267 All Makefile.am files that are subject to the distributions
3268 are now named as Makefile.am.pre. These are ./Makefile.am
3269 and lib/Makefile.am. Others may be changed later.
3271 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3273 * Added invite list, ban list, some key management and connection
3274 error message printing to module formats in the Irssi SILC client.
3276 * Added new silc_client_set_away_message to set the away message
3277 that is back to the person who sent private message. The
3278 affected file lib/silcclient/silcapi.h and the
3279 lib/silcclient/client_prvmsg.c.
3281 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3283 * Fixed the private message sending in the Irssi SILC client,
3284 added local command KEY to the Irssi SILC client.
3286 Added key management and key agreement message formats to the
3287 irssi/src/fe-common/silc/module-formats.[ch].
3289 Added USERS (alias WHO) printing, server/router operator
3290 indication and LIST command printing to the module formats.
3292 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3294 * Fixed channel joining notify handling, cumode notify handling
3295 from Irssi SILC client.
3297 * Added SILC specific module-formats to the Irssi SILC client so
3298 that SILC specific message hilighting, colors etc is possible.
3299 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3301 Added channel mode, channel user mode, actions, notices,
3302 whois and whowas printing to the the module-formats.c.
3304 * Fixed a bug in channel deletion in the server. The channel
3305 is not left to the cache even if the channel founder auth mode
3306 is set when there are no users anymore on the channel. Affected
3307 file silcd/server.c.
3309 * The silc_net_localhost now resolves the entire hostname including
3310 the domain name. Affected file lib/silcutil/silcnet.c.
3312 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3314 * Changed the ask_passphrase client operation to be ascynchronous.
3315 It has now a completion callback and a context that the
3316 application must call after it has got the passphrase from
3317 the user. Affected files lib/silcclient/silcapi.h,
3318 lib/silcclient/protocol.c, lib/silcclient/command.c and
3321 Added SilcAskPassphrase callback that the application calls
3322 to deliver the passphrase to the library.
3324 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3325 The public key verification and especially a certificate
3326 verification is asynchronous procedure.
3328 Added new SILC_SKE_STATUS_PENDING status to indicate the
3329 request is pending and a callback will be called to finalize
3332 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3333 indicate that remote end did not send its public key (or
3334 certificate), even though we require it. Added check for this
3335 condition in the SKE. This was a security bug, now fixed.
3337 Defined new SilcSKEVerifyCbCompletion callback that is called
3338 when the verification process is completed.
3340 The affected files lib/silcske/silcske_status.h and
3341 lib/silcske/silcske.[ch].
3343 * Changed the verify_public_key client operation to be async
3344 as well. Defined SilcVerifyPublicKey callback that is used to
3345 indicate the success of the public key verification process.
3347 Changed the server and client to use the new async client
3350 * Changed the Irssi SILC client's internal scheduler to be called
3351 twice as many times as it used to be. As a result the client
3352 should be a bit faster now. Affected file is
3353 irssi/src/silc/core/silc-core.c.
3355 * Added support to Irssi SILC client of asynchronous public key
3356 verification and passphrase inquiry. Affected file is
3357 irssi/src/silc/core/silc-core.c.
3359 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3361 * Do not say "You have left channel %s" in client library.
3362 Moved it to the application. Affected files are
3363 lib/silcclient/command.c and silc/client_ops.c.
3365 * Fixed silc_client_get_clients. Command context was not
3366 duplicated and was freed memory in the callback. Affected
3367 file lib/silcclient/idlist.c.
3369 * Do not say "you are now talking..." on JOIN command in the
3370 client library. The appliation must handle it.
3372 * Do not say ".. changed topic to" in command reply in the
3373 client libary. The application must handle it.
3375 * Fixed TOPIC command sending in the client library.
3377 * Fixed a memory leak in silc_client_command_free in the file
3378 lib/silcclient/command.c.
3380 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3382 * Imported a modified version of Irssi client to the source tree.
3383 The Irssi will be used to create a new client called
3384 Irssi SILC. Imported to irssi/.
3386 Added silc_core_init_finish function to the Irssi. Affected
3387 file irssi/configure.in.
3389 A lot changes in the Makefile.ams around the irssi tree.
3391 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3393 * Do not rehash if the new size is same as the old size of the
3394 hash table, in the silc_hash_table_rehash*. The affected file
3395 lib/silcutil/silchashtable.c.
3397 * Replaced hash_table_del_by_context calls from the server
3398 (when channel->user_list and client->channels) to the
3399 hash_table_del as it is sufficient and faster.
3401 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3403 * Added silc_hash_table_list, silc_hash_table_get and the
3404 SilcHashTableList structure to provide an alternative way to
3405 traverse the hash table. The affected files are
3406 lib/silcutil/silchashtable.[ch].
3408 * Changed the server's idlist routines to use the hash table
3409 routines to optimize the code.
3411 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3413 * Replaced the client entry's `channel' list and channel entry's
3414 `user_list' list to hash tables for optimized lookup. Changed
3415 the code to use the hash table interface around the code.
3416 Affected file lib/silcd/idlist.[ch].
3418 * Added `auto_rehash' boolean argument to the function
3419 silc_hash_table_alloc to indicate whether the hash table should
3420 auto-rehash when it thinks is appropriate time. It will
3421 increase the hash table size if the there is twice as much
3422 entries in the table than the size of the table, and will
3423 decrease the size if there are twice as less entries than
3424 the size of the table.
3426 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3428 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3430 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3432 * silc_idcache_purge_by_context deletes the entry now by context
3433 as it is supposed to do. Affected file lib/silccore/idcache.c.
3435 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3436 client is not anymore valid (WHOWAS givens the info) and not
3437 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3439 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3441 * Removed the `data' and `data_len' arguments from the ID Cache
3442 interfaces and added `name' argument. ID Cache does not handle
3443 anymore the binary data only a names associated with given ID.
3445 * When hashing a Client ID with silc_hash_id the entire ID is
3446 not hashed anymore, instead only the hash of the Client ID is
3447 hashed. This way we can access the Client ID from the cache
3448 with Client ID but with the hash of the ID (which is a hash of
3449 the nickname) as well without any difference in performance.
3451 Added also silc_idcache_find_by_id_one_ext to do one on one
3452 searching when we have the actual ID. Added also function
3453 silc_hash_client_id_compare. The affected files are
3454 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3456 * When hashing the name associated with a ID it is always done
3457 in lowercase. This way we can access the cache without worrying
3458 about case-sensitivity, even though, for example nicknames are
3461 * Fixed a bug in server with channel message sending. It put
3462 wrong ID type as destination ID. The affected file
3463 silcd/packet_send.c.
3465 * silc_idcache_del_by_context now deletes from all hash tables
3466 by context. Affected file lib/silccore/idcache.c.
3468 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Changed the client library to use the new ID Cache interface.
3471 Changes around the source tree.
3473 * Added silc_hash_table_rehash_ext to rehash with specific
3474 hash function. Affected file lib/silcutil/silchashtable.[ch].
3476 * Added silc_hash_string_compare to compare two strings in the
3477 hash table. Affected file lib/silcutil/silcutil.[ch].
3479 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3481 * Added new function silc_idcache_del_by_context into the
3482 lib/silccore/idcache.[ch].
3484 * Changed the server's ID list routines to use the new ID Cache
3485 interface. Changes around the source tree.
3487 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3489 * Added silc_hash_table_del[_by_context]_ext functions in to the
3490 lib/silcutil/silchashtable.[ch].
3492 Removed silc_hash_table_find_all* routines and added new
3493 silc_hash_table_find_foreach to replace them.
3495 Added silc_hash_table_replace_ext function as extended
3496 replacing function. Separated the simple hash table interface
3497 from the extended hash table interface in the file
3498 lib/silcutil/silchashtable.h.
3500 * Fixed minor bugs and changed it to use some of the new
3501 hash table functions in lib/silccore/idcache.c
3503 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3505 * Added new function silc_hash_table_find_all to return all keys
3506 in the hash table by the specified key. As the hash table is
3507 collision resistant it also makes it possible to have several
3508 duplicate keys in the hash table. This function may be used to
3509 find all of the keys from the hash.
3511 Added user_context arguments to the SilcHashFunction,
3512 SilcHashCompare and SilcHashDestructor to deliver user specified
3515 Added new fuctions silc_hash_table_find[_all]_ext to do
3516 extended lookup with specified hash and compare functions and
3517 specified user contexts.
3519 Added new function silc_hash_table_add_ext to add the key
3520 with specified hash function and user context.
3522 Added new function silc_hash_table_foreach to traverse all
3523 entrys in the hash table. Added SilcHashForeach callback
3526 Added new function silc_hash_table_del_by_context to delete
3527 the entry only if the context associated with the key matches.
3529 Affected files are lib/silcutil/silchashtable.[ch].
3531 * Removed silc_hash_[server/client/channel]_id and added just
3532 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3533 silc_hash_id_compare to compare two ID's using as the hash table
3534 comparison function. Added also silc_hash_data to hash
3535 binary data and silc_hash_data_compare to compare it.
3537 * Removed silc_idlist_find_client_by_hash as it is not needed
3538 anymore. Affected file silcd/idlist.[ch].
3540 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3541 to use internally the SilcHashTable. The new ID Cache is a lot
3542 faster than the old one. Some of the ID Cache interface was also
3543 rewritten and obsolete and stupid functions were removed.
3545 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * Added entry_count field to the SilcHashTable to keep the number
3548 of the entries in the table. Implemented the function
3549 silc_hash_table_rehash. Added new function
3550 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3552 Fixed a minor bug in silc_hash_table_free.
3554 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3555 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3556 into the lib/silcutil/silcutil.[ch].
3558 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3560 * Implemented a collision resistant hash table into the
3561 lib/silcutil/silchashtable[ch]. See the header and the source
3562 for the SilcHashTable API.
3564 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3566 * Merged dotconf version 1.0.2 into lib/dotconf.
3568 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3570 * Do not compile anything in lib/silcsim/* if the SIM support
3571 is not enabled. The tree should now compile without problems
3574 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3576 * Compiled the SILC under cygwin. Compiled and tested briefly
3577 without problems. More tests needed. The SIMs didn't compile
3580 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3582 * Fixed possible crash in silc_get_username in the
3583 lib/silcutil/silcutil.c.
3585 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3587 * Fixed a va_arg in silc/client_ops.c.
3589 * Oops, RC5 routines were named AES and caused some problems
3590 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3592 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3594 * Added new SilcIDIP structure into the lib/silccore/id.h and
3595 replaced the old `ip' fields from all SILC ID's to that type.
3596 This is a step towards IPv6 support.
3598 The silc_id_get_len takes now the ID as an extra argument.
3599 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3600 both IPv4 and IPv6 based ID's.
3602 The affected files are lib/silccore/id.[ch] and other files
3603 around the tree using these routines.
3605 * Removed the ID length arguments in server from various
3606 silc_server_send_notify_* routines -> they are not needed
3609 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3611 * Fixed memory leak in silc_encode_pem_file in the file
3612 lib/silcutil/silcutil.c.
3614 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3616 * Check minor version as well in the SKE. Affected files are
3617 silcd/protocol.c and lib/silcclient/protocol.c.
3619 * Added --identifier option to the server so that an identifier
3620 can be when creating the public key for the server. Affected
3621 file is silcd/silcd.c.
3623 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3624 lib/silccrypt/silcpkcs.c.
3626 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3628 * Register default ciphers and stuff when using -C option with
3629 the server. Affected file sildc/silcd.c.
3631 * Put back the servers public key filename format, it is better
3632 than the new one. For now, the client keys are saved with the
3633 new filename format. The affected file silc/client_ops.c.
3635 * Implemented the Cipher API for the rest of the ciphers that
3636 did not implement it or implemented it the wrong way.
3638 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3640 * Register default ciphers and stuff when using the -S option
3641 in the client. Affected file silc/silc.c. Same also when
3642 creating new key pair with -C option.
3644 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3646 * Fixed the silc_verify_public_key client operation function to
3647 save the public keys differently. The fingerprint is now
3648 used as filename and not the hostname. This way also the
3649 client keys are saved uniquely and not with hostnames. The
3650 affected file is silc/client_ops.c.
3652 * Trimmed the silc_hash_fingerprint function to remove extra
3653 whitespaces from the end of the fingerprint. The affected
3654 file is lib/silccrypt/silchash.c.
3658 * Added silc_cipher_register_default function to register all
3659 default ciphers. It can be used when configuration files
3660 does not exist and the application does not want any specific
3661 ciphers in any specific order.
3663 The SilcDList is now used as silc_cipher_list dynamically
3664 allocated cipher list. Removed the static list all together
3665 and now all ciphers must be allocated to the dynamic list.
3666 The silc_cipher_alloc routine was changed to check only the
3669 All silc_cipher_* routines that used to return int returns
3672 The affected files lib/silccrypt/silccrypt.[ch].
3674 * The same thing was done to silc_hash_* as for silc_cipher_*
3675 routines. Affected files lib/silccrypt/silchash.[ch].
3677 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3678 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3679 Added also silc_pkcs_[un]register[_default] functions.
3680 Removed the data_context from the PKCS API.
3682 * Added silc_hmac_register_default function to register default
3683 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3684 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3685 to unregister all hmacs at once.
3687 * Register the default ciphers, hash functions, PKCSs and HMACs
3688 if client's configuration file does not exist. The affected
3691 * The client did not load the hash functions from the SIM
3692 modules at all. Added support for this. Affected file is
3693 silc/clientconfig.c.
3695 * When decoding public key with silc_pkcs_public_key_decode, check
3696 the supported algorithm only if PKCS are registered. Affected
3697 file lib/silccrypt/silcpkcs.c. The same was done with the
3698 silc_pkcs_private_key_decode.
3700 * Fixed the SILC List routines to keep the list always in order.
3701 It used to change the list's order when traversing the list but
3702 not it preserves the order. Affected file lib/trq/silclist.h.
3704 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3706 * Added the client library to use the SilcSocketConnection's
3707 reference counter (by silc_socket_dup) to prevent the bug that
3708 the socket object may be freed underneath async operation.
3710 * The name resolv library checking fixes in the configure.in.pre.
3713 * Created new version of the protocol drafts for future
3714 development. The -03 drafts are the ones that will be changed
3715 in the trunk now and the -02 will remain as they are.
3717 * Send list of CUMODE notifys to the router when announcing
3718 the channel users to the router. Affected file silcd/server.c.
3719 If the router receiving channel founder CUMODE for a channel
3720 that already has channel founder it will send CUMODE notify
3721 to the sender to remove the channel founder rights from the
3722 announced client. Affected file silcd/packet_receive.c.
3724 * The CUMODE notify may now use Server ID as well as the entity
3725 who changes the mode. Updated protocool specs.
3727 * Updated INSTALL and README files.
3729 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3731 * New web pages in the http://silc.pspt.fi. The pages was
3736 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3738 * Implemented the [DenyConnectin] config section in the server.
3739 Added silc_server_config_denied_conn to check whether incoming
3740 connection is denied. Affected file silcd/serverconfig.[ch].
3742 * Do not check the ports when checking the incoming configuration
3743 data if the port is 0, meaning any. Affected file is
3744 silcd/serverconfig.c.
3746 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3748 * Fixed buffer overflow in silc_string_compare in the file
3749 lib/silcutil/silcutil.c.
3751 * Fixed double free in silc_server_command_leave in the file
3754 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3756 * Fixed the version checking in the server. Affected file is
3759 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3761 * Fixed the configuration data fetching when accepting new
3762 connections in the server. Affected file silcd/server.c.
3764 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3766 * Added `sender_entry' argument to the function
3767 silc_server_packet_relay_to_channel so that we can check
3768 whether some destination actually belongs to the same route
3769 the sender belongs (ie, we must not resend the packet to the
3770 sender). Affected file silcd/packet_send.[ch].
3772 * Added `servername' field to the SilcClientEntry in the server
3773 to hold the name of the server where client is from. Affected
3774 file is silcd/idlist.h.
3776 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3778 * Moved the channel message encrypting in the router betwen
3779 router connections from silc_server_channel_message to the
3780 silc_server_packet_relay_to_channel since we want to check
3781 whether we have anybody channel before encrypting anything.
3782 Affected files silcd/packet_[receive/send].c.
3784 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3786 * Fixed the [AdminConnection] server config section to support
3787 multiple entries. Affected file silcd/serverconfig.c.
3789 * Added support into the server to check the validity of the
3790 incoming connection before executing any KE or authentication
3793 * The connection configuration is now saved to the KE and
3794 connection auth protocol contexts and not fetched anymore in
3795 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3797 * The local hosts listenning address and port is also resolved
3798 now when starting the server. We want to have the socket object
3799 to include the real address and port for the listener. Added
3800 new function silc_net_check_local_by_sock into the files
3801 lib/silcutil/silcnet.[ch].
3803 * Fixed a broadcast bug in server -> do not broadcast if we
3806 * Fixed a routing bug. Do not route broadcast packets ever.
3807 Broadcast packets must be processed always and not routed since
3808 they may be destined to some other host than yourself and thus
3809 would get routed without no good reason. Affected file is
3812 * Added function silc_server_config_is_primary_route to check
3813 whether primary router connection has been configured (a router
3814 configuration that we are initiating). If there is not, we
3815 will assume that there is only two routers in the SILC network
3816 and we will use the incoming router connection as our primary
3817 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3819 * Changed the order of the broadcasting. Broadcast _after_ the
3820 packet has been processed not before. Affected file is
3823 * Fixed a [ClientConnection] parsing bug. The port was never
3824 parsed correctly thus resulting to port 0. Affected file
3825 silcd/serverconfig.c.
3827 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3828 argument and did not set the broadcast packet flag. Affected
3829 file silcd/packet_send.c. Fixed same bug in the function
3830 silc_server_send_notify as well.
3832 * If we receive NEW_ID packet for our own ID in the server, ignore
3835 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3839 * Removed the nickname from the Private Message Payload.
3840 Updated the code and the protocol specs.
3842 * Updated protocol specs for submitting to the IETF.
3844 * Tweaked the Random Number Generator a bit. Affected file
3845 lib/silccrypt/silcrng.c. Exported a new function
3846 silc_rng_[global]_add_noise which can be used to add more
3849 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3851 * Do not parse packets with different timeout when protocol
3852 is active -> may cause problem with rekey. Affected file
3855 * When server receives signoff notify it must not create
3856 new channel key if the client is on any channels since the
3857 sender of the signoff notify will create it.
3859 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3861 * Added printing of error messages during SKE protocol from the
3862 failure packet sent by server during SKE. Affected file
3865 * Removed the client's failure_callback handling with timeout
3866 and handle it immediately when received.
3868 * The SKE library returned wrong type in SUCCESS and FAILURE
3869 packets. They must be 32 bit MSB not 16 bit MSB.
3871 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3873 * Ok, rewrote the logic of the re-key and now it seems to work.
3874 I tested it on high traffic with frequent re-keys without
3875 problems. Added hmac_receive (and renamed hmac to hmac_send)
3876 in SilcClientConnection in lib/silcclient/client.h and
3877 in SilcIDListData in silcd/idlist.h. Also, removed the
3878 SilcPacketParserContext's cipher and hmac fields as they are
3879 not needed anymore and actually caused some problems when
3880 the ciphers and hmac's changed underneath the packet parser.
3882 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3884 * If re-key protocol is active then process the incoming packets
3885 synchronously since we must assure that icoming packets encrypted
3886 with the old key is processed before the new keys is set to
3887 use. This is true other packets than for REKEY packets.
3888 Affected file silcd/server.c. The same was done to client library
3889 as well, affected file lib/silcclient/client.c.
3891 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Fixed bug in client and server to accept the force send if
3894 the packet is send from silc_[server/client]_packet_process
3895 function. Otherwise the packets are never delivered, oops.
3897 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3899 * Disable force sending of packets when REKEY protocol is active.
3900 We must assure that no packet is sent directly when rekey is
3901 performed. All packets must be sent through packet queue.
3902 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3903 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3904 function is silc_[server/client]_packet_send_real to check
3907 * Replaced the SIM paths from example config files to
3908 /usr/local/modules. Also, make install creates now
3909 /usr/local/silc/logs directory to hold all the SILC server
3912 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3914 * Made the configure.in.pre work on Solaris. Patch by salo.
3916 * Made all ciphers compatible with non-x86 machines. Defined
3917 CBC mode macros into lib/silccrypt/ciphers_def.h.
3919 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3921 * Fixed the make install.
3923 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3925 * When MAC computation fails the silc_packet_decrypt returned 0
3926 even though it was supposed to return -1. Fixed this. The
3927 affected file is lib/silccore/silcpacket.c.
3929 * Do not replace the config files in /etc/silc (in make install)
3930 if they already exist. Affected file ./Makefile.am.
3932 * Do not send re-key packets immediately but through packet queue.
3933 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3935 * Changed silc_net_check_host_by_sock to return FALSE if the
3936 IP/DNS could not be resolved. Though, it returns the IP address
3937 now even if it could not resolve it (but returns also FALSE).
3938 Affected file lib/silcutil/silcnet.[ch].
3940 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3942 * Added silc_pkcs_decode_identifier to decode the public key's
3943 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3944 Added also silc_pkcs_free_identifier. Added also new context
3945 SilcPublicKeyIdentifier.
3947 * Added -S option to the silc client. It is used to dump the
3948 contents of the specified public key file.
3950 * Changed the PKCS api to return the public key length when
3951 setting the public key.
3953 * Fixed a fatal bug in the public and private key file loading.
3954 Affected file lib/silccrypt/silcpkcs.c.
3956 * Execute the packet parsing for client with zero (0) timeout
3957 if the protocol is active. Affected file silcd/server.c.
3959 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3961 * Made the key generation options to the silcd program. Added
3962 -C option, equivalent to client's option.
3964 * Added new [ServerKeys] config section to the server. It
3965 configures the server's public and private key.
3967 * Defined generic Public Key Payload into the protocol
3968 specification to send specific type of public keys and
3971 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3972 public key or certificate.
3974 * Implemented the GETKEY command to the server and to the
3975 client library and on user interface.
3977 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * Made preliminary `make install' work.
3981 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3983 * Added SilcServerRekey context into silcd/idlist.h.
3985 * Added the PFS support as defined in the specification to the
3986 SKE protocol. Affected files lib/silcske/*.c.
3988 * Added `ske_group' field to the SilcServerRekey context to hold
3989 the number of the SKE group that is used with PFS in re-key.
3990 Affected file silcd/idlist.h.
3992 * Added PFS re-key support to the server. Affected file is
3995 * Added silc_protocol_cancel to cancel execution of the next
3996 state of the protocol. Affected file is
3997 lib/silccore/silcprotocol.[ch].
3999 * Added the re-key support with and without PFS to the client
4000 library. Re-key is performed once in an hour, by default.
4002 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4003 Added silc_client_rekey_callback and silc_client_rekey_final.
4004 Affected files are lib/silcclient/protocol.[ch] and
4005 lib/silcclient/client.[ch].
4007 * Removed the `hmac_key' and `hmac_key_len' fields from the
4008 SilcClientConnection structure; not needed. Affected file is
4009 lib/silcclient/client.h.
4013 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * Do not ask whether user wants to use the negotiated private key
4016 for private messages, just use it. Affected file is
4017 silc/local_command.c.
4019 * Added `send_enc_key' and `enc_key_len' fields to the
4020 SilcIDListData structure since they are needed in the re-key
4021 phase. Affected file is silcd/idlist.[ch].
4023 * Implemented the simple re-key protocol into the server.
4024 Affected files silcd/server.c and silcd/protocol.[ch]. The
4025 re-key will be performed once in an hour, by default.
4027 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4028 Added silc_server_rekey, silc_server_rekey_callback and
4029 silc_server_rekey_final.
4031 * Removed Tunneled flag from the protocol. Updated the code
4032 and the specifications.
4034 * Adde `pfs' field to the SilcIDListData to indicate whether
4035 the PFS is to be performed in the re-key. Affected file is
4038 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4040 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4041 int64 of at least the xintXX size. If void * is less that 4
4042 bytes uint32 * will be used. Defined bool as boolean.
4044 * Changed _ALL_ unsigned long and unsigned int to uint32,
4045 unsgined short to uint16 in the source tree.
4047 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4048 not handle clients that has entry->data.registered == FALSE.
4049 They are not in the network anymore. Affected file is
4052 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4054 * Implemented the sending of the SERVER_SIGNOFF notify in the
4055 server. Affected file is silcd/server.c.
4057 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4058 Added also silc_notify_payload_encode_args into the
4059 lib/silccore/silcnotify.[ch].
4061 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4062 Affected file silcd/packet_receive.c.
4064 * Implemented the SERVER_SIGNOFF notify handling in the client
4065 library. Affected file lib/silcclient/client_notify.c. Also,
4066 implemnted the printing of the SERVER_SIGNOFF info to the
4067 application. Affected file silc/client_ops.c.
4069 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4070 if the deleting was successful. Affected file silcd/idlist.[ch].
4072 * Added support for public key authentication in the connection
4073 authentication protocol in the client library. Affected file
4074 lib/silcclient/protocol.c.
4076 * Changed the server's silc_idlist_get_clients_by_* interface
4077 to support already allocated array so that new entries may be
4078 added to pre-allocated array. Affected file silcd/idlist.[ch].
4079 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4080 and command replies.
4082 * All command reply functions in the server now calls the
4083 pending command callback even if error occured. This way the
4084 error will be delivered to the client as well. Affected files
4085 silcd/command.c and silcd/command_reply.c.
4087 * Fixed INFO command to return local server's info if no server
4088 was provided. Affected file lib/silcclient/command.c.
4090 * Removed RESTART command for good. Updated the code and the
4093 * Rewrote parts of the task system. It is a bit simpler now.
4094 Removed unsued task priorities. The affected files are
4095 lib/silcutil/silctask.[ch].
4097 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4099 * Moved the USERS printing from the library to the application.
4100 Affected files lib/silcclient/command.c and silc/client_ops.c.
4102 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4106 * Added channel key re-key support. The re-key is perfomed
4107 only by the router and is done once in an hour. Added `rekey'
4108 field to the SilcChannelEntry in the server. Affected files
4109 silcd/server.c and silcd/idlist.h.
4111 * Added silc_task_unregister_by_context into the file
4112 lib/silcutil/silctask.[ch].
4114 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4116 * Added SILC_UMODE_GONE mode to indicate when the client is not
4117 present in the SILC network. Added also support to the local
4118 command AWAY that will set this mode. Added support of showing
4119 "xxx is gone" in WHOIS command. The USERS command shows the
4120 gone status as well.
4122 * Fixed setting server and router operator privileges in the
4123 server's UMODE command. Affected file silcd/command.c.
4125 * Merged the SKE KE1 and KE2 payloads into one payload. The
4126 new KE payload is equivalent to the old KE2 payload.
4128 Cleaned up the SKE Start Payload parsing. It now uses the
4129 simple buffer unformatting to do the parsing. A lot faster
4132 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4133 to the SKE that is used to indicate whether both of the SKE
4134 parties should perform authentication. By default only the
4135 responder performs authentication. By setting this flag also
4136 the initiator must do authentication. By default it is unset
4137 since in normal SKE case, client to server connection, only
4138 the responder should do authentication. When doing SKE between
4139 two clients both should perform authentication. Updated the
4140 code and the protocol specs.
4142 * A little fix to IDENTIFY command in the server. Search the
4143 client first by hash not nickname. Affected file is
4146 * Fixed the silc_client_close_connection to support closing
4147 the client to client connections wihtout deleting too much
4148 data. Affected file lib/silcclient/client.c.
4150 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4151 are received if protocol used to be active but is not anymore
4152 the application would crash due to NULL pointer dereference.
4153 Affected files silcd/server.c and lib/silcclient/client.c.
4155 * Added `hash' field to the SilcClientConnection to include
4156 the hash function negotiated in the SKE protocol.
4158 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4159 to set the channel founder authentication data. A client can
4160 claim the founder rights later by providing the authentication
4161 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4162 This way the channel founder can regain the channel founder
4163 privileges even it is left the channel. This works only on
4164 local server and the client must be connected to the same
4165 server to be able to regain the founder rights. Updated the
4166 protocol specs accordingly.
4168 Added support to the CMODE command in the client to set the
4169 founder auth data. Read the README to see how to set it.
4171 Added support to the CUMODE command to claim the founder
4172 rights. Read the README to see how to do it.
4174 Added support for the founder authentication to the Channel
4175 Entry in the server. Affected file silcd/idlist.h.
4177 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4178 server's CMODE command. Affected file silcd/command.c.
4180 * Added the following new functions into lib/silccore/silcauth.[ch]:
4181 silc_auth_get_method and silc_auth_get_data.
4183 * The server now saves the remote hosts public key to the
4184 SilcIDListData pointer. Affected file silcd/protocol.c.
4186 * The normal server now does not remove the channel entry from
4187 the cache if the founder authentication data is set. It used
4188 to remove it if the founder was the last one on the channel on
4189 the server and left the channel. The auth data is saved and
4190 if the channel is re-joined later the old entry is used with
4191 the old auth data. Affected files silcd/command_reply.c and
4194 * Removed the `pkcs' field from the SilcIDListData structure
4195 in the server; it is not used. Affected file silcd/idlist.h.
4197 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Fixed packet processing on slow links. Partial packets were
4200 never re-processed because the incoming data buffer was cleared
4201 by the application. Application must not directly clear the
4202 sock->inbuf, the packet processing routines handle it. Fixed
4203 this in client library and in server.
4205 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * Fixed the WHOIS and IDENTIFY send reply function to really
4208 check whether to send list or just one entry. Affected file
4211 * Cleaned up the LEAVE command's channel key distribution. The
4212 affected file silcd/command.c.
4214 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4215 can enforce the channel mode as well. In that case the ID
4216 includes the ID of the server. The code now enforces the
4217 mode change if the router have different mode than the server.
4219 * The notify client operation with CMODE_CHANGE notify can now
4220 return NULL client_entry pointer if the CMODE was not changed
4221 by client. Application must check for this.
4223 * Added <Server ID> argument to INFO command to support server
4224 info fetching by Server ID.
4226 * Added silc_server_announce_get_channel_users to get assembled
4227 packets of channel users of the specified channel. Affected
4228 file silcd/server.[ch].
4230 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4231 was freed underneath the ID Cache.
4233 * Re-announce clients when the server received CHANNEL_CHANGE
4234 notify from the router. Affected file silcd/packet_send.c.
4236 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4238 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4239 crashed since it did not handle the fact that there is no cipher
4240 called "3" and didn't check the error condition. Now fixed.
4242 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4243 flag. It can be used to send message requests.
4245 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * Implemented the RESTART command in the client.
4249 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4250 notice type messages. Added notice printing to the user
4253 * The channel keys are not re-generated if the channel's mode
4254 is PRIVKEY, ie private key on the channel exists. Affected
4255 files silcd/server.c and silcd/command.c.
4257 * Fixed a little bug in channel message delivery when channel
4258 private keys are set in the server. Affected file is
4259 silcd/packet_send.c.
4261 * Changed the setting on channel->on_channel = TRUE from the
4262 silc_client_save_channel_key to the JOIN command reply. The
4263 key payload is not received if the private channel key is set.
4264 Affected file lib/silcclient/command_reply.c and the
4265 lib/silcclient/client_channel.c.
4267 * When the CMODE_CHANGE notify is sent and the channel private
4268 key mode is removed the channel key must be re-generated in
4269 other cells as well. Added this support for the router in the
4270 silcd/packet_receive.c.
4272 * Added new local command NOTICE to send notice message on
4273 channel. Affected file silc/local_command.[ch].
4275 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4277 * Added new local command ME to the client. It is used to send
4278 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4279 some action. Affected file silc/local_command.[ch].
4281 * Changed channel_message and private_message client operations
4282 to deliver the message flags to the application. Added also
4283 the `flags' arguments to the silc_client_send_channel_message
4284 and silc_client_send_private_message functions. Affected file
4287 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4289 * Redefined the Private Message Payload to support private message
4290 keys and to support the new private message flags. Updated
4291 the protocol specs. Flags makes it possible to have for example
4292 CTCP style messages.
4294 * Added new type SilcPrivateMessagePayload and defined an API
4295 for it in the lib/silcclient/silcprivate.[ch].
4297 * Tested private message private keys successfully. Tested the
4298 private message key set, unset and list commands with the new
4301 * Redefined the Channel Message Payload to include the channel
4302 message flags (equal with private message flags) to support
4303 for example CTCP style messages.
4305 * Defined some of the message (for channel and private message)
4306 flags. Updated the protocol specs and added the flags to the
4307 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4309 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Added SilcKeyAgreementStatus type to the key agreement routines
4312 to indicate the current status and error if one occured.
4313 The status types are defined in the lib/silcclient/silcapi.h.
4315 * Added new local command KEY that is used to set and unset private
4316 keys for channels, set and unset private keys for private messages
4317 with remote clients and to send key agreement requests and
4318 negotiate the key agreement protocol with remote client. The
4319 key agreement is supported only to negotiate private message keys,
4320 it currently cannot be used to negotiate private keys for channels,
4321 as it is not convenient for that purpose.
4323 * Fixed a minor pending callback setting bug in the function
4324 silc_client_get_client_by_id_resolve, now the function works.
4325 Affected file lib/silcclient/idlist.c.
4327 * Added function silc_net_get_local_port to get local bound
4328 port by socket. Added to lib/silcutil/silcnet.[ch].
4330 * Added `sockets' and `sockets_count' fields to the SilcClient
4331 object. They hold the sockets of the listenning sockets in
4332 the client. Listenning sockets may be for example the key
4333 agreement server. Affected file lib/silcclient/client.[ch].
4334 Added functions the silc_client_add_socket and the
4335 silc_client_del_socket. They are exported to the application
4338 * Added ~./silc/clientkeys to support other client's public keys.
4340 * Renamed verify_server_key client operation to verify_public_key
4341 and added one argument to indicate the type of the connection
4342 (server, client etc.).
4344 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4346 * Added silc_server_connection_auth_request to handle the
4347 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4348 silcd/packet_receive.[ch].
4350 * Added silc_server_send_connection_auth_request into the
4351 silcd/packet_send.c to send the connection auth request packet.
4353 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4356 * Fixed the public key authentication in responder side in the
4357 server. The `auth_data' pointer includes the SilcPublicKey
4358 not the path to the public key. Affected file silcd/protocol.c.
4360 * Implemented the public key authentication in the initiator side
4361 in the server. Affected file silcd/protocol.c.
4363 * Removed the [RedirectClient] config section from the server
4364 configuration. Is not needed and I don't want to implement it.
4366 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4368 * Cleaned up the CMODE command in the server. It now works
4369 correctly and supports all the modes defined in the protocol.
4370 Affected file is silcd/command.c.
4372 * Added `hmac_name' field to the SilcChannelEntry in the server
4373 to hold the default HMAC of the channel. It can be set when
4374 creating the channel (with JOIN command). Affected files
4377 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4378 type to indicate the change of the current cipher and hmac
4379 on the channel. Client can safely ignore the <cipher> argument
4380 (if it chooses to do so) since the CHANNEL_KEY packet will
4381 force the channel key change anyway. The <hmac> argument is
4382 important since the client is responsible of setting the new
4383 HMAC and the hmac key into use.
4385 * Fixed the CMODE command in the client library as well.
4387 * Tested CMODE command in router environment successfully.
4389 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4391 * Show the version of the remote client (or server) when connecting
4392 to the server. It is logged to the log file. Affected file
4393 is silcd/protocol.c.
4395 * Fixed the KILLED notify handling in the client library. The
4396 client must be removed from all channels when receiving the
4399 Also, do not remove the client entry when giving the KILL
4400 command but when the KILLED notify is received.
4402 * Removed silc_idlist_find_client_by_nickname from the server.
4403 Not needed anymore. Affected files silcd/idlist.[ch].
4405 * Implemented the CHANNEL_CHANGE notify type handling to the
4406 server. Affected file silcd/server.c.
4410 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4412 * Added silc_server_send_notify_invite to send the INVITE
4413 notify between routers.
4415 * Implemented the INVITE command correctly to the server.
4417 * Implemented the INVITE notify type handling in the server.
4419 * Implemented the INVITE command to the client library and on the
4422 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4424 * Added function silc_server_get_client_resolve to find the
4425 client entry by ID from all ID lists and then resolve it
4426 (using WHOIS) if it cannot be found. Affected file is
4429 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4431 * Implemented the BAN command to the client library.
4433 * The JOIN command in the server now checks the invite list
4436 * Changed the silc_command_reply_payload_encode_va and the
4437 silc_command_payload_encode_va to support that if argument is
4438 NULL it ignores and checks the next argument. Affected file
4439 lib/silccore/silccommand.c.
4441 * Added silc_server_send_notify_ban to send the BAN notify
4442 type between routers.
4444 * Chaned the silc_notify_payload_encode to support that if
4445 argument is NULL it ignores and checks the next argument.
4446 Affected file lib/silccore/silcnotify.c.
4448 * Tested ban lists in router environment successfully.
4450 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4452 * Implemented BAN command to the server, in silcd/command.[ch].
4454 * Removed the BAN and INVITE_LIST modes from the CMODE command
4457 * Added function silc_string_match to regex match two strings.
4458 Affected files lib/silcutil/silcutil.[ch].
4460 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4462 * Redefined parts of the SilcChannelEntry in the server to support
4463 the new ban and invite lists.
4465 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4467 * Redefined the INVITE command. The same command can be used to
4468 invite individuals to the channel but also to manage the invite
4469 list of the channel (to add to and remove from the invite list).
4470 Updated the protocol specs.
4472 * Added new command SILC_COMMAND_BAN that can be used to manage
4473 the ban list of the channel. Updated the protocol specs.
4475 * Removed the channel modes: the SILC_CMODE_BAN and the
4476 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4477 in the CMODE command. The equivalent features are now available
4478 using INVITE and BAN commands. Updated the protocol specs.
4480 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4481 in the network about change in the current ban list. The notify
4482 type is not used by the client.
4484 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4485 support the invite lists.
4487 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4489 * Added new function silc_string_regexify that converts string
4490 including wildcard characters into regex string that can
4491 be used by the GNU regex library. Added into the file
4492 lib/silcutil/silcutil.[ch].
4494 Added silc_string_regex_combine to combine to regex strings
4495 into one so that they can be used as one regex string by
4496 the GNU regex library. Added into the file
4497 lib/silcutil/silcutil.[ch].
4499 Added silc_string_regex_match to match two strings. It returns
4500 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4502 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Imported GNU regex to the soruce tree into lib/contrib.
4505 Fixed some compiler warning from the regex.c.
4507 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4509 * Fixed MOTD command in the server to work in router environment.
4511 * Fixed the MOTD command in the client library to support
4512 the server argument in the command.
4514 * Added `nickname_len' argument to the silc_idlist_add_client
4515 in the server, as the `nickname' argument may be binary data
4518 * Added silc_idlist_get_channels to return all channels from
4521 * Implemented LIST command to the server. Affected file is
4524 * Implemented the LIST command to the client library and on the
4527 * Added [<user count>] argument to the LIST command reply.
4528 With private channels the user count is not shown.
4530 * Updated TODO and README.
4532 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * The client entry's data.registered must be TRUE even with
4535 global client entry on global client list. The data.registered
4536 is used to check whether the client is anymore in the network,
4537 for example with WHOWAS command so it must be valid.
4539 * Fixed the WHOWAS command in the server. It now actually works
4540 in router environment. Added function into silcd/command_reply.c
4541 silc_server_command_reply_whowas_save.
4543 * Added silc_idlist_purge function to the silcd/idlist.c
4544 to periodically purge the ID Cache.
4546 * Fixed INFO command in the server. It works now in router
4547 environment. Added <server name> argument to the INFO command
4548 reply. Updated the protocol specs.
4550 * Fixed minor bug in silc_idcache_purge to not purge if the
4551 expire value is zero.
4553 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4554 they were buggy because of the WHOWAS information.
4556 * Fixed local command MSG to handle the async resolving of
4557 the remote client properly. It used to fail the first MSG.
4558 Affected file silc/local_command.c.
4560 * Added `data_len' field to SilcIDCache context.
4562 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4564 * Update TODO. Todo in commands in the server.
4566 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4568 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4569 used by routers as broadcast packet to inform other routers
4570 about the changed user mode.
4572 Implemented the notify handling in the server. Affected file is
4573 silcd/packet_receive.c. Added the function
4574 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4576 * Added new generic Channel Payload and deprecated the New Channel
4577 Payload. The New Channel Payload is now the generic Channel
4580 * Added new argument `mode' to the silc_server_send_new_channel
4581 as it is required in the Channel Payload now.
4583 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4584 and created a new and real SilChannelPayload to represent the
4585 new generic Channel Payload. Implemented the encode/decode
4586 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4588 * Added silc_server_get_client_channel_list to return the list
4589 of channels the client has joined for WHOIS command reply.
4590 Affected file silcd/server.[ch].
4592 * Implemented the channel list sending in the WHOIS command reply
4593 in server and in the client.
4595 Implemented the channel list displaying on the user interface
4596 as well. Affected file silc/client_ops.c.
4598 * Added silc_channel_payload_parse_list to parse list of Channel
4599 Payloads. It returns SilcDList list of SilcChannelPayloads.
4600 Client for example can use this function to parse the list of
4601 channels it receives in the WHOIS command reply. The caller
4602 must free the list by calling silc_channel_payload_list_free.
4603 Affected files lib/silccore/silcchannel.[ch].
4605 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4607 * Added one new argument <user mode> to the WHOIS command reply
4608 to return the mode of the user in SILC. Updated the protocol
4611 Implemented it to the server and client.
4613 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4615 * Fixed the mode printing on the user interface on joining.
4616 Affected file silc/client_ops.c.
4618 * Implemented the UMODE command and user modes in general to the
4619 client library and to the user interface.
4621 * Implemented the UMODE command to the server.
4623 * The server now sends UNKNOWN_COMMAND error status if client sends
4624 unknown command. Affected file silcd/command.c.
4626 * All server commands now handle the command identifier the right
4627 way when sending the command reply to the client. The client can
4628 use to identify the command replies with the identifier.
4630 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4632 * Added silc_server_get_client_route to resolve the route to
4633 the client indicated by the client ID. Affected file is
4636 * Added silc_server_relay_packet as general function to relay
4637 packet to arbitrary destination. This deprecates functions
4638 like _send_private_message_key, _relay_notify etc. Affected
4639 file is silcd/packet_send.[ch].
4641 Removed silc_server_send_key_agreement,
4642 silc_server_send_private_message_key and
4643 silc_server_packet_relay_notify functions from the file
4644 silcd/packet_send.[ch].
4648 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4649 server. Affected file silcd/packet_receive.[ch].
4651 * Implemented the KILL command to the client. Implemented the
4652 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4653 Affected files lib/silcclient/command[_reply].c and
4654 lib/silcclient/client_notify.c. Implemented the KILL notify
4655 printing in the user inteface.
4657 * Fixed a lot silc_parse_nick memory leaks from the client
4658 library in the file lib/silcclient/command.c.
4660 * Changed the silc_server_send_notify_on_channels's `sender'
4661 argument from SilcSocketConnection to SilcClientEntry to
4662 check the sender as entry and not as connection object and not
4663 to send to the client provided as argument. The affected file
4664 is silcd/packet_send.[ch].
4666 * The notify packets that are destined directly to the client used
4667 to not to be processed by the server. Now changed that and the
4668 server processes all notify packets. After relaying the packet
4669 to the client the notify packet is processed in the server.
4671 * The silc_server_free_client_data now checks whether there is
4672 pending outgoing traffic for the client and purges the data to
4673 the network before removing the client entry.
4675 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4677 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4678 an client is killed from the SILC Network. Updated the protocol
4681 Added new function silc_server_send_notify_killed to the
4682 silcd/packet_send.[ch].
4684 * Added function silc_server_packet_relay_notify to relay notify
4685 packets that are destined directly to a client. In this case
4686 the server does not process the notify packets but merely relays
4687 it to the client. Affected file silcd/packet_send.[ch].
4689 Added also silc_server_packet_process_relay_notify to check
4690 whereto relay the notify. Affected file is
4691 silcd/packet_receive.[ch].
4693 * Implemented the KILL command to the server.
4697 * Added the backup schema desgined last fall to the protocol
4698 specs for everyone to see. The specification is in the
4699 *-spec-xx.txt draft and the packet type definitions for the
4700 backup routers is in *-pp-xx.txt draft. Thusly, added also
4701 new packet type SILC_PACKET_CELL_ROUTERS.
4703 * A big security problem in the implementation discovered. The
4704 signoff of an client did not cause new channel key generation
4705 which it of course should've done. The channel keys must be
4706 always re-generated when client leaves (or signoffs) the channel.
4707 The silc_server_remove_from_channels funtion now handles
4708 the channel key re-generation.
4710 * Added `sender' argument to the silc_server_send_notify_on_channels
4711 to not to send the client provided as argument. Affected file
4712 silcd/packet_send.[ch].
4714 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4716 * Implemented OPER and SILCOPER commands into the server and
4719 * Added silc_auth_verify and silc_auth_verify_data to verify
4720 the authentication directly from the authentication payload.
4721 It supports verifying both passphrase and public key based
4722 authentication. Affected file lib/silccore/silcauth.[ch].
4724 * Added `hash' field to the SilcIDListData structure. It is the
4725 hash negotiated in the SKE protocol. Affected file is
4728 * Slight redesigning of the SilcAuthPayload handling routines.
4729 Do not send SilcPKCS but SilcPublicKey as argument.
4731 * Implemented the public key authentication support to the
4732 serverconfig. The public key is loaded from the provided path
4733 and saved as authentication data to void * pointer. Thus,
4734 changed the unsigned char *auth_data to void *auth_data;
4736 * Fixed SHUTDOWN command to send the reply before the server
4737 is shutdown. :) Affected file silcd/command.c.
4739 * Fixed fatal bug in CONNECT command. The hostname was invalid
4740 memory and server crashed. Affected file silcd/command.c.
4742 * Fixed fatal bug in CLOSE command. The server_entry became
4743 invalid but was referenced later in the command. Affected file
4746 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4748 * Fixed fatal bug in failure packet handling. Server ignored
4749 the failure and thus crashed when it came.
4753 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4755 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4756 that the command may be executed only once in (about) 2 seconds.
4757 The old SILC_CF_LAG flag is same but allows command bursts up
4758 to five before limiting.
4760 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4761 server code. Various commands now includes the CF_LAG_STRICT
4762 flag to disallow any kind of miss-use of the command.
4764 * Fixed the silc_buffer_unformat to not to allocate any data
4765 if the length of the data is zero. It used to allocate the
4766 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4768 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Changed the format of AdminConnection configuration section
4771 in the server. Added username of the admin to the format.
4772 Affected files silcd/serverconfig.[ch].
4774 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4775 to return admin configuration data by host, username and/or
4778 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4780 * Implemented WHOWAS command to the server. Added the functions:
4782 silc_server_command_whowas_parse,
4783 silc_server_command_whowas_send_reply,
4784 silc_server_command_whowas_from_client and
4785 silc_server_command_whowas_from_server
4787 * Added <Client ID> argument to the WHOWAS command reply. Updated
4788 the protocol specs accordingly.
4790 * Implemented WHOWAS command and command_reply to the client
4793 Implemented the WHOWAS printing on the user interface.
4795 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4797 * Added new argument to the WHOWAS command reply, the real name.
4798 It is an optional argument. Updated the protocol specs.
4800 * Added SilcIDCacheDestructor callback that is registered when
4801 the SilcIDCache is allocated. The callback is called when
4802 an cache entry in the ID Cache expires, or is purged from the
4803 cache. Added into lib/silccore/idcache.[ch].
4805 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4806 to destruct the client entries when the cache entry expires.
4807 Other ID Cache's in server and in the client library ignores
4810 * If the ID Cache entry's `expire' field is zero then the entry
4811 never expires. Added boolean `expire' argument to the
4812 silc_idcache_add function in the lib/silccore/idcache.[ch].
4813 If it is TRUE the default expiry value is used.
4815 * Added silc_server_free_client_data_timeout that is registered
4816 when client disconnects. By default for 5 minutes we preserve
4817 the client entry for history - for WHOWAS command.
4819 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4821 * Added support to the server to enforce that commands are not
4822 executed more than once in 2 seconds. If server receives
4823 commands from client more frequently, timeout is registered
4824 to process the commands. Affected file silcd/command.c.
4825 Added new function silc_server_command_process_timeout.
4827 * Changed NICK_NOTIFY handling in client library to check that
4828 if the client's nickname was changed, so there is no need to
4829 resolve anything from the server.
4831 * Removed error printing from the WHOIS and IDENTIFY commands.
4832 If error occurs then it is ignored silently in the client library.
4833 The application, however, may map the received error to
4834 human readable error string. The application currently maps
4835 the NO_SUCH_NICKNAME error to string.
4837 * Made the command status message public to the application. Moved
4838 them from lib/silcclient/command_reply.c to
4839 lib/silcclient/command_reply.h. The application can map the
4840 received command status to the string with the
4841 silc_client_command_status_message function.
4843 * Added check to the server to check that client's ID is same
4844 as the Source ID in the packet the client sent. They must
4847 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4849 * Added dist-bzip hook to the Makefile.am to make bzip2
4850 compressed distributions.
4852 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4854 * Server now enforces the maximum length for the nickname and
4855 the channel as protocol specification dictates. 128 bytes for
4856 nickname and 256 bytes for channel name.
4858 * Moved the WHOIS printing to the application. The client libary
4859 does not print out the WHOIS information anymore, the application
4860 must do it. Renamed silc_client_command_reply_whois_print to
4861 the silc_client_command_reply_whois_save.
4863 The client's idle time is also sent to the application now, and
4864 the idle is shown on screen.
4866 * Added silc_client_command_reply_identify_save to save the
4867 received IDENTIFY entries.
4869 * Do not check for channel private keys in message sending and
4870 reception if the channel does not have the PRIVKEY mode set.
4871 Affected file lib/silclient/client_channel.c.
4873 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4875 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4876 just surfaced after chaning the JOIN procedure.
4878 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4880 * Added silc_client_get_clients_by_list to get client entries
4881 from Client ID list, that is returned for example by JOIN
4882 and USERS command replies. The application should use this
4883 function for example when JOIN command reply is received to
4884 resolve the clients already on the channel (library does not
4885 do that anymore as USERS command reply is not used in the JOIN
4886 procedure anymore). Affected files lib/silcclient/silcapi.h and
4887 lib/silcclient/idlist.c.
4889 * JOIN command reply and USERS command reply returns now SilcBuffer
4890 pointers instead of unsigned char pointers when returning
4891 the client list and mode list.
4893 * Added <Client ID> argument to the JOIN command reply, mainly
4894 for the server to identify for which client the command was
4895 originally sent. Updated protocol specs accordingly.
4897 * Added SilcDlist private_key pointer to the SilcChannelEntry
4898 in the client to support the channel private keys. Affected
4899 file is lib/silcclient/idlist.h.
4901 * Added SilcChannelPrivateKey argument to the function
4902 silc_client_send_channel_message so that application can choose
4903 to use specific private ke if it wants to. If it is not provided,
4904 the normal channel key is used, unless private keys are set.
4905 In this case the first (key that was added first) is used
4906 as the encryption key.
4908 * Implemented the support for channel private key handling.
4909 Implemented the following functions:
4911 silc_client_add_channel_private_key,
4912 silc_client_del_channel_private_keys,
4913 silc_client_del_channel_private_key,
4914 silc_client_list_channel_private_keys and
4915 silc_client_free_channel_private_keys
4917 Affected file lib/silcclient/client_channel.c.
4919 * Added the support for the private keys in the channel message
4920 sending and encryption and in the message reception and
4921 decryption. Affected funtions are
4922 silc_client_send_channel_message and silc_client_channel_message.
4924 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4926 * Added SKE's key verify callback to the client library's
4927 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4929 * Removed the statement that server (or router) must send USERS
4930 command reply when joining to the channel so that the client
4931 knows who are on the channel. Instead, the client list and
4932 client's mode list is now sent in the JOIN command reply to the
4933 client who joined channel. This is better solution.
4935 * Added function silc_server_get_users_on_channel and function
4936 silc_server_save_users_on_channel to the silcd/server.[ch].
4938 * Removed function silc_server_command_send_users from the
4941 * Do not show topic on the client library anymore. The topic is
4942 sent in the command reply notify to the application and the
4943 application must show the topic now.
4945 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * Added client searching by nickname hash into the IDENTIFY and
4948 WHOIS commands in the server as they were clearly missing from
4949 them. Affected file is silcd/command.c.
4951 * Fixed a bug in private message receiving in the client library.
4952 The remote ID was freed and it wasn't supposed, now it is
4955 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4957 * Minor fix to the channel payload; allocate the data area, as it
4958 needs to be of specific length.
4960 * If the key agreement port is zero then the operating
4961 system will define the bound port. Affected files are
4962 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4964 * Added new function silc_channel_payload_decrypt into the file
4965 lib/silccore/silcchannel.[ch].
4967 * Moved the channel message etc, check from silc_packet_decrypt
4968 to applications. The library calls now a generic
4969 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4970 when the packet is either normal or special. This was done to
4971 allow more wide range of checking that was not allowed when
4972 the code was in library. Now applications can do virtually any
4973 checks to the packet and return to the library the decision how
4974 the packet should be processed. Affected files are
4975 lib/silccore/silcpacket.[ch].
4977 Added silc_server_packet_decrypt_check to the server and
4978 silc_client_packet_decrypt_check to the client library.
4980 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4981 to send with specified source and destination information.
4983 * Channel message delivery between routers was broken after the
4984 channel key distribution was fixed earlier. The channel key
4985 was used be to distributed to other routers as well which is not
4986 allowed by the protocol. Now this is fixed and channel keys
4987 really are cell specific and the channel message delivery between
4988 routers comply with the protocol specification.
4990 * Fixed various commands in server to check also the global list
4991 for the channel entry and not just the local list. The affected
4992 file silcd/command.c.
4994 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4996 * Added assert()s to buffer formatting and unformatting routines
4997 to assert (if --enable-debug) when error occurs. Affected
4998 file: lib/silcutil/silcbuffmt.c.
5000 * Changed to auto-reconnect to check whether the remote host is
5001 router and register the re-connect timeout if it is. It used
5002 to check that whether we are normal server, but router must do
5003 auto-reconnect with another router as well. Affected file
5006 * Removed the [<key len>] option from CMODE command as the cipher
5007 name decides the key length, nowadays. See the defined ciphers
5008 from the protocol specification.
5010 * Added [<hmac>] option to the CMODE command to define the HMAC
5011 for the channel. Added SILC_CMODE_HMAC channel mode.
5013 * Added [<hmac>] option for the JOIN command so that user can
5014 select which HMAC is used to compute the MACs of the channel
5017 * Added Hmac field to the Channel Message Payload. The integrity
5018 of plaintext channel messages are now protected by computing
5019 MAC of the message and attaching the MAC to the payload. The
5020 MAC is encrypted. Now, it is clear that this causes some
5021 overhead to the size of the packet but rationale for this is that
5022 now the receiver can verify whether the channel message decrypted
5023 correctly and also when private keys are set for the channel the
5024 receiver can decrypt the packet with several keys and check from
5025 the MAC which key decrypted the message correctly.
5027 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5028 lib/silccrypt/silccipher.[ch].
5030 * Added silc_hash_len to return the digest length into the
5031 lib/silcrypt/silchash.[ch].
5033 * Rewrote parts of Silc Channel Payload interface in the
5034 lib/silccore/silcchannel.[ch]. The encode function now also
5035 encrypts the packet and parse function decrypts it.
5037 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5039 * Fixed a minor formatting bug in the SKE's key material processing.
5040 It actually might have processed the keys wrong way resulting
5043 * Redefined the mandatory HMAC algorithms and added new algorithms.
5044 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5045 and hmac-md5 truncated to 96 bits. The mandatory is now
5046 hmac-sha1-96. Rest are optional (including the one that used
5047 to be mandatory). Rationale for this is that the truncated HMAC
5048 length is sufficient from security point of view and can actually
5049 make the attack against the HMAC harder. Also, the truncated
5050 HMAC causes less overhead to the packets. See the RFC2104 for
5053 * Added new [hmac] configuration section. The SKE used to use
5054 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5055 is of course wrong. The official names that must be proposed in
5056 the SKE are the ones defined in the protocol specification
5057 (hmac-sha1-96 for example). The user can configure any hmac
5058 using any hash function configured in the [hash] section. At
5059 least, the mandatory must be configured.
5061 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5063 * Added HMAC list to the SKE proposal list. It has now both
5064 hash algorithm list and HMAC list. This makes the protocol
5065 incompatible with previous versions. The SKE now seems to work
5066 the way it is supposed to work, for the first time actually.
5068 * Defined plain Hash algorithms to the protocol specification.
5071 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5073 * Implemented support for key agreement packets into the server.
5074 Added functions silc_server_key_agreement and
5075 silc_server_send_key_agreement. Other than these functions,
5076 server has nothing to do with this packet.
5078 * Added support for private message key packets into the server.
5079 Added functions silc_server_private_message_key and
5080 silc_server_send_private_message_key.
5084 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5085 called in the protocol's final callback instead in the END
5086 protocol state. This makes a little more sense and in the same
5087 time in client we can use the same protocol routines for normal
5088 key exchange and to key agreement packet handling as well.
5090 * Added to both client's and server's KE protocol context the
5091 SilcSKEKeyMaterial pointer to save the key material. We will
5092 bring the key material to the protocol's final callback by doing
5093 this. The final callback must free the key material.
5095 * Added SKE's packet_send callback into client's KE protocol
5096 context so that the caller can choose what packet sending function
5097 is used. This way we can use different packet sending when
5098 doing normal SKE when doing key agreement packet handling (in
5099 the key agreement packet handling we do not want to encrypt
5102 * Implemented the responder side of the key agreement routines
5103 in the client. The client can now bind to specified port and
5104 accept incoming key negotiation. The key material is passed
5105 to the application after the protocol is over.
5107 * Implemented the processing of incoming Key Agreement packet
5108 in the client. Added function silc_client_key_agreement to
5111 * Implemented the intiator side of the key agreement routines
5112 in the client. The client can now initiate key agreement with
5113 another remote client. The key material is passed to the
5114 application after the protocol is over.
5116 * Created client_keyagr.c to include all the key agreement
5119 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5120 SILC_TASK_CALLBACK except that it is not static.
5122 * Created client_notify.c and moved the Notify packet handling
5123 from the client.[ch] into that file.
5125 * Created client_prvmsg.c and moved all private message and
5126 private message key routines from the client.[ch] into that file.
5128 * Create client_channel.c and moved all channel message and
5129 channel private key routines from the client.[ch] into that file.
5131 * Changed silc_client_get_client_by_id_resolve to resolve with
5132 WHOIS command instead of IDENTIFY command, in the file
5133 lib/silclient/idlist.c.
5135 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * Implemented the SKE's responder side to the Client library.
5139 * When FAILURE is received to the protocol do not trust it
5140 blindly. Register a timeout to wait whether the remote closes
5141 the connection as it should do it, only after that process the
5142 actual failure. This was changed to both client and server.
5144 * Added client_internal.h to include some of the structures
5145 there instead of client.h in lib/silcclient/.
5147 * Added function silc_task_unregister_by_callback to unregister
5148 timeouts by the callback function.
5150 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * Some "Incomplete WHOIS info" errors has been appearing on the
5153 log files. Took away the entry->userinfo check from WHOIS
5154 reply sending. The entry->userinfo is now " " if client did not
5155 provide one. I thought this was fixed earlier but something
5156 is wrong still. Let's see if the error still appears.
5158 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5160 * Fixed a minor bug in the login when the channel key is
5161 re-generated in the server. It used to generate the key in
5162 wrong order and thus caused problems in the channel traffic.
5164 * Fixed a minor bug in channel key distsribution after
5165 KICK command. The key was not sent to the router even though
5168 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5170 * Added silc_ske_process_key_material_data as generic routine
5171 to process any key material as the SILC protocol dictates. The
5172 function is used by the actual SKE library but can be used by
5173 applications as well. This relates to the private message keys
5174 and the channel private keys since they must be processed the
5175 same way the normal SILC session keys. The protocol dictates
5176 this. Affected files: lib/silcske/silcske.[ch].
5178 Added also silc_ske_free_key_material to free the
5179 SilcSKEKeyMaterial structure.
5181 * Defined silc_cipher_set_key function to set the key for
5182 cipher without using the object's method function. The affected
5183 files: lib/silccrypt/silccipher.[ch].
5185 * Implemented silc silc_client_add_private_message_key,
5186 silc_client_add_private_message_key_ske,
5187 silc_client_del_private_message_key,
5188 silc_client_list_private_message_keys and
5189 silc_client_free_private_message_keys functions in the
5192 Added functions silc_client_send_private_message_key to send
5193 the Private Message Key payload and silc_client_private_message_key
5194 to handle incoming Private Message Key payload.
5196 * Added Cipher field to the Private Message Key payload to set
5197 the cipher to be used. If ignored, the default cipher defined
5198 in the SILC protocol (aes-256-cbc) is used.
5200 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5202 * Removed lib/silcclient/ops.h file.
5204 Redefined parts of the SILC Client Library API. Created new
5205 file silcapi.h that deprecates the ops.h file and defines the
5206 published Client Library API. Defined also private message key
5207 API and channel private key API into the file.
5209 This is the file that the application must include from the
5210 SILC Client Library. Other files need not be included by
5211 the application anymore.
5213 * Added new key_agreement client operation callback and also
5214 defined the Key Agreement library API for the application.
5216 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5218 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5219 is used by clients to request key negotiation between another
5220 client in the SILC network. If the negotiation is started it
5221 is performed using the SKE protocol. The result of the
5222 negotiation, the secret key material, can be used for example
5223 as private message key.
5225 Implemented the Key Agreement payload into the files
5226 lib/silccore/silauth.[ch].
5228 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5230 * Redefined ciphers for the SILC protocol. Added some new ciphers
5231 and defined the key lengths for the algorithms. Changed the
5232 code accordingly. The default key length is now 256 bits.
5234 * Fixed SKE key distribution function silc_ske_process_key_material
5235 when the key length is more than 128 bits. The default key
5236 length in SILC is now 256 bits.
5238 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5239 to indicate unsupported algorithm.
5241 * Renamed rijndael.c to aes.c and all functions as well.
5243 * Fixed a long standing channel key setting bug in client library.
5244 Weird that it has never surfaced before.
5246 * Fixed bug in channel deletion. If the entire channel is removed
5247 then it must also delete the references of the channel entry
5248 from the client's channel list as the client's channel entry and
5249 the channel's client entry share same memory.
5251 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5253 * Implemented CONNECT and SHUTDOWN commands in the client.
5255 * Implemented CLOSE command to the client.
5257 * Added the function silc_idlist_find_server_by_name into the
5258 files silcd/idlist.[ch].
5260 Added the function silc_idlist_find_server_by_conn into the
5261 files silcd/idlist.[ch].
5263 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5265 * DIE command was renamed to SHUTDOWN. Updated the both code
5268 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5269 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5271 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5274 * Added function silc_server_create_connection function to create
5275 connection to remote router. My server implementation actually
5276 does not allow router to connect to normal server (it expects
5277 that normal server always initiates the connection to the router)
5278 so the CONNECT command is only good for connecting to another
5281 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5283 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5284 or some other client was kicked from the channel.
5286 Implemented the handling of the notify type to both client
5289 Implemented silc_server_send_notify_kicked to send the KICKED
5290 notify. It is used to send it to the server's primary router.
5292 * Implemented the KICK command into server and client.
5294 * Added `query' argument to the silc_idlist_get_client function
5295 to indicate whether to query the client from server or not if
5298 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5299 to indicate that the client is not channel founder.
5303 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5305 * Removed the rng context from SilcPacketContext structure and
5306 changed that the packet routine uses the Global RNG API.
5308 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5310 * Added support for quit message that client can "leave" on the
5311 channel when it quits the SILC. It is ditributed inside the
5312 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5314 Added silc_server_free_client_data that will take the
5315 signoff message as argument.
5317 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5319 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5321 * Updated parts of the protocol specification to keep it up
5324 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5326 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5327 payloads in one packet.
5329 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5330 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5331 use now the new List flag.
5333 * Also deprecated the following packet types: REPLACE_ID,
5334 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5336 * Added list support for Notify packet in server.
5338 * Added silc_server_send_notify_channel_change to send the
5339 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5340 the silc_server_send_replace_id.
5342 * Added silc_server_send_notify_nick_change to send the
5343 NICK_CHANGE notify type. Deprecates the function
5344 silc_server_send_replace_id.
5346 * Added silc_server_send_notify_join to send the JOIN notify type.
5347 Deprecates the function silc_server_send_new_channel_user.
5349 * Added silc_server_send_notify_leave to send LEAVE notify type.
5350 Deprecates the function silc_server_send_remove_channel_user.
5352 * Added silc_server_send_notify_cmode and
5353 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5354 types. Deprecates the silc_server_send_set_mode function.
5356 * Added SERVER_SIGNOFF notify type to indicate that server has
5357 quit. This means that all clients on the channel from that
5358 server will drop. This can be also used when netsplit happens.
5360 Deprecated REMOVE_ID packet type since it is not needed anymore
5363 Added silc_server_send_notify_server_signoff to send the
5364 SERVER_SIGNOFF notify type. Deprecates the function
5365 silc_server_send_remove_id.
5367 Added also silc_server_send_notify_signoff to send the
5368 SIGNOFF notify type.
5370 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5371 SILC protocol from this day on. Changed the protocol
5372 specification as well.
5374 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5375 notify type. It is used between routers to notify about
5376 topic changes on a channel.
5378 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5381 * Partly updated the protocol specification to comply with the
5382 changes now made. It is still though a bit outdated.
5384 * The JOIN notify type now takes one extra argument <Channel ID>.
5385 The packet used to be destined to the channel but now the
5386 JOIN type may be sent as list thus it is impossible to
5387 destine it to any specific channel. By adding this argument
5388 it is again possible.
5390 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5392 * Added CREDITS file. The CHANGES and CREDITS file will appear
5393 in the distribution as well.
5395 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5397 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5398 types in the server's silcd/packet_receive.c.
5400 * Implemented CMODE and CUMODE to work in router environment.
5402 * Fixed minor encoding and decoding buglet from the
5403 lib/silccore/silcmode.c.
5405 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5408 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5410 * Changed all SilcConfigServer* and silc_config_server* to
5411 SilcServerConfig* and silc_server_config*, respectively.
5414 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Associated the ID (client or server ID) to the Authentication
5417 Payload to avoid any possibility of forging. Updated the
5418 protocol specification and the code accordingly.
5420 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5422 * The RSA key length is now save to the RsaKey context in the
5423 key generation process in lib/silccrypt/rsa.c. The key length
5424 is now used to figure out the maximum size of the block allowed
5425 to be encrypted/signed.
5427 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5428 is equivalent to the silc_mp_mp2bin but does not allocate any
5431 * Changed silc_mp_mp2bin API to take length argument. If it is
5432 non-zero then the buffer is allocated that large. If zero, then
5433 the size is approximated using silc_mp_sizeinbase, which however
5436 * Created Global RNG API which is global RNG that application can
5437 initialize. After initializing, any routine anywhere in the
5438 code (including library) can use RNG without allocating a new
5439 RNG object. This was done to allow this sort of use of the
5440 RNG in code that has no chance to allocate RNG object. All
5441 applications currently allocate this and many routines in the
5442 library use this. Affected file lib/silccrypt/silcrng.[ch].
5444 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5445 it to use the Global RNG API.
5447 * Defined Authentication Payload into protocol specification that
5448 is used during SILC session to authenticate entities. It is
5449 used for example by client to authenticate itself to the server
5450 to obtain server operator privileges.
5452 Implemented this payload into the lib/silccore/silcauth.[ch].
5453 Implemented also routines for public key based authentication
5454 as the new protocol specification dictates.
5456 Moved definitions of different authentication methods from
5457 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5459 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5460 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5461 silc_pkcs_verify_with_hash functions into the file
5462 lib/silccrypt/silcpkcs.[ch].
5464 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5466 * The client entry's userinfo pointer must be always valid.
5467 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5468 will fail since it requires the userinfo. Now, the userinfo
5469 is allocated as "" if actual userinfo does not exist. Actually,
5470 it must exist and it is totally Ok to drop client connections
5471 that does not announce the userinfo. However, we will make
5472 this workaround for now.
5474 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5475 to return the remote port by socket.
5477 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5479 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5480 SILC_SERVER_PENDING_EXEC and added an new macro
5481 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5482 data or when error occurs while processing the pending command.
5484 Added new argument `destructor' into silc_server_command_pending
5485 and to the SilcServerCommandPending object. This destructor is
5486 now called after calling the pending callback or if error occurs
5487 immediately. If error occurs the actual pending callback won't
5488 be called at all - only the destructor. The destructor may be
5489 NULL if destructor is not needed.
5491 All this applies for client library code as well. Similar
5492 changes were made there as well for the pending commands.
5494 In the client, the application must now allocate the
5495 SilcClientCommandContext with the silc_client_command_alloc
5498 * Added reference counter to the SilcServerCommandContext. Added
5499 function silc_server_command_alloc and silc_server_command_dup
5502 Same type of functions added to the client library for the same
5505 * Removed the cmd_ident from IDListData away since it is now
5506 global for all connections. It is the command identifier used
5507 in command sending and with pending commands. The affected file
5510 * Added reference counter to the SilcSocketConnection objecet to
5511 indicate the usage count of the object. The object won't be
5512 freed untill the reference counter hits zero. Currently only
5513 server uses this, and client ignores it. The client must be
5514 set to use this too later. The affected files are
5515 lib/silccore/silcsockconn.[ch]. Added also the function
5516 silc_socket_dup to increase the reference counter.
5518 This was mainly added because it is possible that the socket
5519 is removed underneath of pending command or other async
5520 operation. Now it won't be free'd and proper DISCONNECTING
5521 flags, etc. can be set to avoid sending data to connection that
5522 is not valid anymore.
5524 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5525 the connection. After that it sets SILC_SET_DISCONNECTED.
5526 It is, however, possible that the socket data is not still freed.
5527 The silc_server_packet_process now checks that data is not
5528 read or written to connection that is DISCONNECTED. The socket
5529 get's freed when the reference counter hits zero.
5531 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5533 * Changed the client operation API: channel_message operation's
5534 `sender' is now the client entry of the sender, not the nickname
5535 and the `channel' is the channel entry, not the channel name.
5537 In the private_message operation the `sender' is now also the
5538 client entry of the sender not the nickname.
5540 Affected file is lib/silcclient/ops.h and all applications
5541 using the client operations.
5543 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5545 * Moved the calling of ops->connect() from connect_to_server_final
5546 into receive_new_id functin since that is the point when the
5547 client is actually allowed to send traffic to network. The
5548 affected file is lib/silcclient/client.c.
5550 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5552 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5553 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5554 (if needs broadcasting) instead of broadcasting the packets one
5555 by one which would make a burst in the network traffic.
5557 * Added `broadcast' argument to the functions in silcd/server.[ch]
5558 silc_server_create_new_channel[_with_id] to indicate whether
5559 to send New Channel packet to primary router.
5561 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5563 * Added new function into the silcd/server.[ch] files:
5564 silc_server_create_new_channel_with_id to create new channel with
5565 already existing Channel ID.
5567 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5568 lib/silccore/silcpacket.h. This packet is used t send list of
5569 Set Mode payloads inside one packet. Server uses this to set
5570 the modes for the channels and clients on those channels, that it
5571 announced to the router when it connected to it. The protocol
5572 specification has been updated accordingly.
5574 * The silc_server_new_channel did not handle the packet coming
5575 from normal server as it normally does not send that. However,
5576 when it announces its channels it does send it. Implemented
5577 the support for that.
5579 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5580 into the file lib/silccore/id.h.
5582 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5584 * Fixed memory leaks in the functions silc_idlist_del_client,
5585 silc_idlist_del_channel and silc_idlist_del_server in the file
5586 silcd/idlist.c. All of those leaked like a sieve.
5588 * Fixed some small memory leaks in the client's function
5589 silc_client_notify_by_server.
5591 * Added functions into silcd/server.c: silc_server_announce_clients,
5592 silc_server_announce_channels and silc_server_announce_server.
5593 These functions are used by normal and router server to announce
5594 to its primary router about clients, channels and servers (when
5595 router) that we own. This is done after we've connected to the
5598 These functions effectively implements the following packet types:
5599 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5600 and SILC_PACKET_NEW_ID_LIST.
5602 * Added new functions into the silcd/packet_receive.[ch]:
5603 silc_server_new_id_list, silc_server_new_channel_list and
5604 silc_server_new_channel_user_list to handle the incoming
5605 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5607 * Added support of changing Channel ID in the function
5608 silc_server_replace_id. If the server that announces a channel
5609 to the router already exists in the router (with same name but
5610 with different Channel ID), router is responsible to send
5611 Replace ID packet to the server and force the server to change
5612 the Channel ID to the one router has.
5614 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5615 client that the Channel ID has been changed by the router. The
5616 normal server sends this to the client. Client must start using
5617 the new Channel ID as the channel's ID.
5619 Implemented handling of this new type into lib/silcclient/client.c
5620 into the function silc_client_notify_by_server.
5622 * Added new function silc_idlist_replace_channel_id into the files
5623 silcd/idlist.[ch] to replace the Channel ID.
5625 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5627 * Call silc_server_command_identify_check always when processing
5628 the IDENTIFY command in silcd/command.c
5630 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5632 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5633 send keepalive packets. The packet can be sent by clients,
5634 servers and routers.
5636 Added function silc_socket_set_heartbeat into the file
5637 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5638 If not set, the heartbeat is not performed. The actual
5639 heartbeat is implemented in the low level socket connection
5640 library. However, application is responsible of actually
5643 Added silc_server_send_heartbeat to send the actual heartbeat
5644 packet into silcd/packet_send.[ch]. Server now performs
5645 keepalive with all connections.
5647 * Added silc_task_get_first function into lib/silcutil/silctask.c
5648 to return the timeout task with shortest timeout. There was a bug
5649 in task unregistration that caused problems. TODO has been
5650 updated to include that task system must be rewritten.
5652 * The client library will now resolve the client information when
5653 receiving JOIN notify from server for client that we know but
5654 have incomplete information.
5656 * Rewrote parts of silc_server_remove_from_channels and
5657 silc_server_remove_from_one_channel as they did not remove the
5658 channel in some circumstances even though they should've.
5660 * Encryption problem encountered in server:
5662 The LEAVE command used to send the Channel Key packet to the
5663 router immediately after generating it. However, the code
5664 had earlier sent Remove Channel user packet but not immediately,
5665 ie. it was put to queue. The order of packets in the router
5666 was that Channel Key packet was first and Remove Channel User
5667 packet was second, even though they were encrypted in the
5668 reverse order. For this reason, MAC check failed. Now, this
5669 is fixed by not sending the Channel Key packet immediately but
5670 putting it to queue. However, this is more fundamental problem:
5671 packets that are in queue should actually not be encrypted
5672 because packets that are sent immediately gets encrypted
5673 actually with wrong IV (and thus MAC check fails). So, packets
5674 that are in queue should be encrypted when they are sent to
5675 the wire and not when they put to the queue.
5677 However, the problem is that the current system has not been
5678 designed to work that way. Instead, the packet is encrypted
5679 as soon as possible and left to the queue. The queue is then
5680 just purged into wire. There won't be any fixes for this
5681 any time soon. So, the current semantic for packet sending
5684 o If you send packet to remote host and do not force the send
5685 (the packet will be in queue) then all subsequent packets to the
5686 same remote host must also be put to the queue. Only after the
5687 queue has been purged is it safe again to force the packet
5690 o If you send all packets immediately then it safe to send
5691 any of subsequent packets through the queue, however, after
5692 the first packet is put to queue then any subsequent packets
5693 must also be put to the queue.
5695 Follow these rules and everything works fine.
5697 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5699 * Added new function silc_server_remove_clients_by_server to
5700 remove all client entries from ID list when the server connection
5701 is lost. In this case it is also important to invalidate all
5702 client entires as they hold the invalid server entry. This
5703 fixes fatal bug when server has lost connection and will reconnect
5706 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5708 * Made some sanity checks to silc_server_daemonise like to check
5709 whether the requested user and group actually exists.
5711 * Added sanity check to SKE's silc_ske_responder_finish to check
5712 that the public and private key actually is valid.
5714 * Invalidate the client's nickname when receiving Replace ID
5715 packet and the Client ID is being replaced. This means that the
5716 server will query the nickname if someone needs it (client)
5719 * Sort the ID Cache in client library when the ID Cache data
5720 has changed (needs sorting).
5722 * Do not allow for SILC client to create several connections to
5723 several servers. The client does not support windows right now
5724 and generating multiple connections causes weird behaviour.
5726 Irssi-silc client does support windows and can handle several
5727 connections without problems, see: www.irssi.org and SILC plugin.
5729 * Fixed some places where client was added to the IDList. The
5730 rule of thumb is following (in order to get everything right):
5731 If the client is directly connected local client then the
5732 `connection' argument must be set and `router' argument must be
5733 NULL to silc_idlist_add_client function. If the client is not
5734 directly connected client then the `router' argument must
5735 bet set and the `connection' argument must be NULL to the
5736 silc_idlist_add_client function.
5738 * The funtion silc_server_packet_send_local_channel actually did
5739 not check whether the client was locally connected or not. It
5740 does that now. Fixed a bug related to LEAVE command.
5742 * Fixed Remove Channel User payload parsing bug in server's
5743 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5745 * The server's silc_server_save_channel_key now checks also the
5746 global ID list for the channel as it might not be in the local
5747 list. Fixed a bug related to LEAVE command.
5749 * Is this the end of the [<unknown>] buglet that has been lurking
5750 around for a long time? A little for loop fix in server's
5751 silc_server_command_whois_parse that is used by both IDENTIFY
5752 and WHOIS command. At least, this was a clear bug and a cause
5753 of one type of [<unknown>] buglet.
5755 * WHOIS and IDENTIFY commands call the function
5756 silc_server_command_[whois/identify]_check function even if
5757 we are not router server.
5759 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Added --with-gmp configuration option. If set the GMP
5762 is always compiled in the SILC source tree. If not set then
5763 it is checked whether the system has the GMP3 installed. If
5764 it has then the GMP won't be compiled (the system's headers
5765 and library is used), if it doesn't have it then the GMP is
5766 compiled in the SILC source tree.
5768 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5770 * Changed RSA private exponent generation to what PKCS #1
5771 suggests. We try to find the smallest possible d by doing
5772 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5773 not security fix but optimization.
5775 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5777 * Added new config entry [Identity] to fork the server and run
5778 it as specific user and group. A patch from Bostik.
5780 * Imported Dotconf configuration library into lib/dotconf.
5781 This will be used to create the SILC configuration files later.
5782 It will appear in the distsribution after this commit.
5784 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5786 * A big code auditing weekend happening. Auditing code for
5787 obvious mistakes, bugs and errors. Also, removing any code
5790 Removed files for being obsolete:
5792 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5793 inline in the file lib/silcutil/silcbuffer.h)
5795 o lib/silcutil/silcbufutil.c (the header has inline versions)
5797 Changed code to fix possible error conditions:
5799 o The buffer formatting routines now check that the destination
5800 buffer really has enough space to add the data. This applies for
5801 both buffer formatting and unformatting
5802 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5803 unformatting was changed to accomodate following rules:
5804 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5805 sent to the function while XXX_*STRING will not allocate or copy
5806 the data into the buffer. Instead it sets the pointer from the
5807 buffer into the pointer sent as argument (XXX_*STRING used to
5808 require that the pointer must be allocated already). This change
5809 makes this whole thing a bit more consistent and more optimized
5810 (note that the data returned in the unformatting with XXX_*STRING
5811 must not be freed now). The routines return now -1 on error.
5813 o Tried to find all code that use buffer_format and buffer_unformat
5814 and added return value checking to prevent formatting and
5815 especially unformatting errors and possible subsequent fatal
5818 o Changed ske->x and ske->KEY to mallocated pointers in
5819 lib/silcske/silcske.h. Fixed possible data and memory leak.
5821 o Added return value checking to all *_parse* functions. Fixed
5822 many memory leaks as well.
5824 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5825 so that buffer overflows would not happen. All code now also
5826 checks the return value as it can fail.
5828 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5830 * Added reconnection support to server if the normal server looses
5831 its connection to the router (for example if router is rebooted).
5832 The server performs normal reconnection strategy implemented
5833 to the server. Affected file silcd/server.c.
5835 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * Added new packet type SILC_PACKET_SET_MODE that is used to
5838 distribute the information about changed modes (for clients,
5839 channels and clients channel modes) to all routers in the
5840 network. Updated the protocol specification accordingly.
5842 Added functions into silcd/packet_send.c and
5843 silcd/packet_receive.c: silc_server_send_set_mode,
5844 silc_server_set_mode.
5846 Added new files silcmode.[ch] into lib/silccore that implements
5847 the encoding and decoding of Set Mode Payload. Added new type
5848 SilcSetModePayload. Moved the definitions of different modes
5849 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5851 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5853 * Oops, a little mistake in server's connection authentication
5854 protocol. The protocol is not ended with FAILURE but with
5855 SUCCESS if the authentication is Ok. :) Affected file is
5858 * Implemented NICK_CHANGE notify handling in server in the file
5859 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5860 the local clients on the channel. After the changing nickname
5861 in router environment snhould work and the [<unknown>] nickname
5862 should appear no more.
5864 The silc_server_replace_id function that receives the Replace ID
5865 payload now sends the NICK_CHANGE notify type also in the file
5866 silcd/packet_receive.c
5868 * Changed WHOIS and IDENTIFY command to support the maximum amount
5869 of arguments defined in protocol specs (3328 arguments). This
5870 fixed a bug that caused problems when there were more than three
5873 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5875 * Added extra parameter, command identifier, to the
5876 silc_client_send_command so that explicit command identifier
5879 Changed that ID list routines uses specific command identifier
5880 when sending WHOIS/IDENTIFY requests to the server so that they
5881 can be identified when the reply comes back.
5883 Affected files lib/silcclient/command.[ch],
5884 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5886 * Added `sender' argument to silc_server_packet_send_to_channel
5887 to indicaet the sender who originally sent the packet to us
5888 that we are now re-sending. Ignored if NULL. Affected file
5889 silcd/packet_send.[ch].
5891 * Added some server statistics support in silcd/server_internal.h
5892 SilcServerStatistics structure and around the server code. Also
5893 send some nice statistics information when client is connecting
5896 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5898 * Fixed channel ID decoding in server's JOIN command reply in
5899 silcd/command_reply.c
5901 * Fixed braodcasting of replace ID payload to not to send it if
5902 we are standalone server in silcd/packet_receive.c.
5904 * Fixed all channel message sending routines to not to send
5905 packets to clients that has router set, since they are routed
5906 separately in the same function earlier. Affects file
5907 silcd/packet_send.c and all channel packet sending functions.
5909 * In USERS reply, res_argv[i] are not allocated, the table
5910 is allocated. Thus changed that free the table, not its
5913 * In server's whois_check and identify_check if the client is
5914 locally connected do not send any WHOIS commands - they are not
5917 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5919 * Fixed some minor bugs in client when sending WHOIS command. The
5920 arguments was in wrong order.
5922 * Removed statis function add_to_channel from server in
5923 silcd/command.c that was previously used with the joining but
5926 * Tested USERS command in router environment successfully with two
5927 routers, two servers and two clients.
5929 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * Reorganized the USERS command and command reply in client library
5932 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5933 When the command is given by user we register a pending command
5934 callback that will reprocess the command after the reply has been
5935 received from the server. When reprocessing the packet we then
5936 display the information. Thus, the USERS information is displayed
5937 now in the command callback instead of in the command reply
5938 callback. The processing of the command is same as previously
5939 when server has sent the command reply in the JOINing process.
5941 * Added to USERS command in silcd/command_reply.c to join the client,
5942 we didn't use to know about, to the channel after we've created
5943 a client entry for it. Also, for clienet we did know already still
5944 check whether it is on the channel or not and add it if not.
5946 * Removed silc_server_command_join_notify as the function and its
5949 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5951 * Changed the client's pending command handling to the same as the
5952 server's pending command handling. It is also now possible to
5953 execute command reply functions from other command reply
5954 function as the function callbacks for commands and command
5955 replies are one and same. The pending commands are not static
5956 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5957 in client connection context. Thus, pending commands are server
5958 connection specific as it is convenient.
5960 Changed the function silc_client_command_pending and
5961 silc_client_command_pending_del and added new function
5962 silc_client_command_pending_check. Removed the
5963 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5966 * Added cmd_ident, current command identifier, to the client
5967 connection context in lib/silcclient/client.h to keep track on
5968 command identifiers used in command sending. Client's command reply
5969 function handling now supports the mandatory command identifiers.
5971 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5972 funtions in client to fully support pending command callbacks.
5974 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5975 as one of the arguments to the application in the command reply
5978 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5979 before first releasing SILC but came back. Now it is removed again
5980 and should come back nomore. The FORWARDED flag was used only
5981 by the JOINing procedure by forwarding the command packet to router.
5982 Now, the JOINing procedure has been changed to more generic (due
5983 to various router environment issues) and FORWARDED is not needed
5984 anymore for anything. The protocol specification is yet to be
5987 Now, removed silc_server_packet_forward from server and the flag
5988 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5990 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5992 * Renamed NAMES command to USERS command. The NAMES was named that
5993 due to historical reasons. Now it is renamed. Also, rewrote
5994 parts of the USERS command. The nickname list is not sent anymore
5995 by the server. Only Client ID and mode lists are sent in the USERS
5996 command. Changed this also to the protocol specification.
5998 The client now resolves the names and stuff after it receives
5999 the USERS list from the server when joining to the channel.
6001 * WHOIS and IDENTIFY commands has been changed to support multiple
6002 Client ID's per command. One can now search for multiple users
6003 in the network by sending only one WHOIS or IDENTIFY command.
6004 Changed the code and the protocol specifications.
6006 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6007 uses silc_server_command_whois_parse to parse the request. */
6009 * If normal server, do not parse the WHOIS and IDENTIFY requests
6010 before sending it to the router. Saves some time.
6012 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6014 * Fixed JOIN command on client library. Wrong number of arguments
6015 used to crash the client.
6017 * Added silc_server_channel_has_global function to check whether
6018 channel has global users or not.
6020 * Added silc_server_channel_has_local function to check whether channel
6021 has locally connected clients on the channel.
6023 * The silc_server_remove_from_one_channel now checks whether the
6024 channel has global users or not after given client was removed from
6025 the channel. It also checks whether the channel has local clients
6026 on the channel anymore. If it does not have then the channel entry
6027 is removed as it is not needed anymore.
6029 * The silc_server_notify now checks on JOIN notify whether the joining
6030 client is one of locally connected or global. If it is global then
6031 the channel has now global users on the channel and that is marked
6032 to the channel entry. Also, it now saves the global client to
6033 global list who is joining and JOINs it to the channel. This is
6034 for normal server, that is.
6036 Changed silc_server_send_notify_on_channel,
6037 silc_server_packet_relay_to_channel and
6038 silc_server_packet_send_to_channel check if we are normal server
6039 and client has router set (ie. global client) do not send the
6040 message to that client, as it is already routed to our router.
6042 * Implemented LEAVE notify type handling in silc_server_notify
6045 * Tested LEAVE command in router environment successfully. Tested
6046 with two routers, two servers and two clients.
6050 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6052 * Implemented SIGNOFF notify type handling in silc_server_notify
6055 * silc_server_remove_id now removes the client entry from all channels
6056 it has joined and thusly sends SIGNOFF notify type.
6058 * Rewrote the NAMES list generation in server by removing two excess
6059 loops. The lists are created now inside one loop.
6061 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6063 * silc_server_remove_channel_user checks now also global list
6064 for channel and client.
6066 * silc_server_new_channel_user checks now both local and global
6067 list for channel and client. Fixed a bug in client id decoding.
6068 Used to decode wrong buffer.
6070 * silc_server_channel_message checks now both local and global
6071 list for channel entry.
6073 * Tested channel joining (hence JOIN) in router environment
6074 successfully. Tested with two routers, two servers and two
6077 * Tested channel message sending in router environment successfully.
6079 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6081 * Added silc_server_save_channel_key into server.[ch] to save the
6082 received channel key in Channel Key payload processing. It is
6083 also used in JOIN command reply handling.
6085 Equivalent function silc_client_save_channel_key added into
6086 client.[ch] into client library.
6088 * Changed JOIN command reply to send information whether the channel
6089 was created or not (is existing already) and the channel key
6090 payload. Changed protocol specs accordingly.
6092 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6093 the request was sent by ID and not by nickname. Crashed on
6096 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6098 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6099 now correctly save the received data.
6101 * silc_server_free_sock_user_data now notifies routers in the
6102 network about entities leaving the network.
6104 At the same time implemented functions silc_server_remove_id
6105 and silc_server_send_remove_id to receive and send REMOVE_ID
6106 packets. The packet is used to notify routers in the network
6107 about leaving entities. The ID removed will become invalid in
6110 * Added function silc_idlist_del_server into server. Removes and
6111 free's server entry from ID list.
6113 * silc_server_private_message function now checks, if we are router,
6114 that the destination ID really is valid ID, naturally.
6116 * In router when NEW_ID packet is received (for new client) the
6117 hash of the Client ID is saved in the ID Cache but the
6118 client->nickname is set to NULL, instead of putting the hash
6121 IDENTIFY command now also checks that client->nickname must be
6122 valid. If it is not if will request the data from the server who
6123 owns the client. Added new function
6124 silc_server_command_identify_check.
6126 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6127 to set the command to already allocated Command Payload.
6129 * Tested private message sending in router environment with two
6130 routers, two servers and two clients. Fixed minor bugs and now
6133 * Fixed segfault from client's NAMES command. Used to crash if
6136 * Forwarded packets must not be routed even if it is not destined
6137 to the receiver. Changed server code comply with this.
6139 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6141 * Added `require_reverse_mapping' boolean value to ServerParams
6142 structure. If TRUE (not default) the server will require that
6143 the connecting host has fully qualified domain name.
6145 If the reverse mapping is not required and hostname could not be
6146 found the IP address is used as hostname.
6148 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6150 * Implemented version string checking to both client and server.
6151 The check is incomplete currently due to the abnormal version
6152 strings used in development version of SILC.
6154 * Changed all command functions in server to use the new
6157 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6159 * Changed char *data to unsigned char *data in ID Cache system to
6160 support binary data as ID Cache data. Changed code to support
6161 binary data in lib/silccore/idcache.c.
6163 * Renamed silc_server_packet_relay_command_reply to
6164 silc_server_command_reply as it is normal packet receiving
6165 function. Rewrote the function to accept command replys for
6166 servers and not only for clients.
6168 * Mark remote router always as registered server if we are connecting
6169 to it. Otherwise, commands sent by the router to us are ignored.
6171 * All ID List find routines now returns the ID Cache Entry pointer
6172 as well if requested.
6174 * WHOIS command works now in router environment, tested with two
6175 routers, two servers and two clients.
6177 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6178 in router environment (as it is almost equivalent to WHOIS) but
6179 hasn't been tested thoroughly. Added new functions:
6181 silc_server_command_identify_parse
6182 silc_server_command_identify_send_reply
6183 silc_server_command_identify_from_client
6184 silc_server_command_identify_from_server
6186 * Disabled route cache adding because adding two different ID's with
6187 same IP replaces the old cache entry thus giving wrong route.
6188 The entry->router->connection is always the fastest route anyway
6189 so route cache may not be needed. Of course, new routes maybe
6190 established after receiving the ID when the entry->router->connection
6191 might not be anymore the most optimal.
6193 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6195 * Add route cache for received ID for fast routing.
6197 * Added silc_server_packet_route to route received packet on router
6198 that is not destined to us.
6200 * Renamed silc_server_get_route to silc_server_route_get.
6202 * Added id_string and id_string_len fields into SilcServer to
6203 include encoded ServerID for fast comparing without excess
6204 encoding of the ID's.
6206 * Cleaned up WHOIS command on server side. Added following static
6209 silc_server_command_whois_parse
6210 silc_server_command_whois_check
6211 silc_server_command_whois_send_reply
6212 silc_server_command_whois_from_client
6213 silc_server_command_whois_from_server
6215 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6216 arguments in command replies. All command functions should be
6217 updated to use this macro.
6219 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6221 * Minor typo fixes on command reply handling on server.
6223 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6225 * Added silc_server_command_add_to_channel internal routine to add
6226 the client to the channel after router has created the channel and
6227 sent command reply to the server.
6229 * Added generic silc_server_send_command to send any command from
6232 * Use static buffer with ID rendering instead of duplicating data.
6234 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6236 * Fixed a channel user mode bug when joining to a channel server gave
6237 everybody channel founder rights, oops.
6239 * We mark ourselves as the router of the incoming server connection
6240 if we are router ourselves. This way we can check in some packet
6241 sending functions whether it is locally connected server. For
6242 incoming router connections we put NULL.
6244 * For router sending packets locally means now always sending the
6245 packet cell wide; to local clients and local servers. For normal
6246 server sending packet locally means sending it to only local
6249 * Fixed the JOIN command to really work in router environment. If the
6250 channel is created it is always created by the router. Router is
6251 also responsible of making the initial joining to the channel,
6252 sending JOIN notify to the sending server and distributing
6253 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6254 does not exist server doesn't do anything else but forward the
6255 command to the router which performs everything.
6257 * Added silc_server_send_channel_key function to send the Channel Key
6260 * Added silc_server_create_channel_key to create new channel key. The
6261 channel key is now re-generated everytime someone joins or leaves
6262 a channel, as protocol dictates. Note: channel->key_len is the
6265 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6267 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6268 packet_receive.[ch] to separate packet sending and receiving
6269 routines. The server.[ch] now includes everything else including
6270 actual packet processing (writing and reading data) and other
6273 Renamed silc_server_private_message_send_internal to
6274 silc_server_send_private_message. The routine is still though
6275 used only to relay private messages as server does not send
6276 private messages itself.
6278 Renamed silc_server_new_channel to silc_server_create_new_channel
6279 and added new function sicl_server_new_channel that handles the
6280 incoming New Channel packet. Added also new sending function
6281 silc_server_send_new_channel to send New Channel Payload.
6283 * Added new function silc_server_notify to process incoming notify
6284 packet to the server/router. Server may then relay the notify
6285 to clients if needed.
6287 * Added new function silc_server_new_channel_user to process incoming
6288 New Channel User packet. Router will redistribute the packet and
6289 send JOIN notify to its local clients and locally connected servers
6290 if needed. Normal server will send JOIN notify to its local client
6291 on same channel when received this packet. Added also corresponding
6292 sending function silc_server_send_new_channel_user to sent the
6295 * Added boolean route argument to send_notif_to_channel and
6296 packet_send_to_channel functions to attempt to route the packet
6297 if it is TRUE and send only locally if it is FALSE.
6299 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6301 * silc_server_replace_id now broadcasts the received replace ID
6302 packet if it is not broadcast packet already. The router must
6303 broadcast to inform other routers about changed ID.
6305 * Added backpointer to server's router into SilcServer context in
6306 silcd/server_internal.h.
6308 * Fixed silc_server_packet_broadcast to send correct broadcast
6311 * The channel key is now distributed to the local client as soon
6312 as it is received from the router (in router environment) so that
6313 no other packet may be sent for the channel until client has
6316 * silc_server_remove_channel_user now broadcasts the received
6317 Remove Channel User packet if it is not broadcast packet already.
6318 The router must broadcast to inform other routers about removed
6321 * Added users field into SilcPacketContext that is a reference count
6322 of the context. One can increase the reference count by calling
6323 silc_packet_context_dup which is now changed to just increase the
6324 reference count instead of duplicating the data. The reference
6325 count is decresed by calling silc_packet_context_free that will
6326 free the data after the reference count hits zero.
6328 For now on the packet context and everything allocated into it
6329 (including the raw packet from network) must be freed by calling
6330 the new silc_packet_context_free function. Added also new function
6331 silc_packet_context_alloc that must be used now to allocate the
6332 context. This also means that if a routine is asynchronous from
6333 silc_[client/server]_packet_parse_type the packet context must
6334 be duplicated by calling silc_packet_context_dup. Otherwise it
6335 gets free'd after silc_[client/server]_packet_parse_type returns.
6336 Also, one must remember that if packet is duplicated then its
6337 reference count must be decresed by calling the free function as
6338 many times as it was duplicated.
6340 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6341 from both client and server.
6343 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6345 * Made joining to a channel working in router environment.
6347 * Cleaned up JOIN command on server side and create function
6348 silc_server_command_join_channel internal routine to make the
6351 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6353 * Changed silc_command_pending list to SilcDList. Also, added
6354 `ident' field to SilcServerCommandPending structure to identify
6355 the reply and to call correct callback.
6357 Added silc_server_command_pending_check function to replace the
6358 corresnponding macro. The silc_command_pending list is not
6361 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6362 to set identifier to previously allocated Command Payload. It
6363 is used to set identifier for command when resending Command
6366 * Added silc_command_payload_encode_payload to encode Command
6367 Payload buffer from SilcCommandPayload structure.
6369 * Added silc_argument_payload_encode_payload to encode Argument
6370 payload buffer from SilcArgumentPayload structure.
6372 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6374 * Changed WHOIS command to support router connection on server side.
6375 The whois request is always sent to router unless the server is
6376 standalone server. After server has received the reply from the
6377 router will it send the reply to the client.
6379 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6380 broadcast received broadcast packet. The function is used only
6381 by router. The broadcast packet is always sent to the router's
6384 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6385 render given ID to printable string, for log files for example.
6387 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6389 * Made basic router to router connections working. At least they
6390 can now connect to each other but nothing really works the way
6391 they are supposed - yet.
6393 * Added new initiator token to RouterConnection configuration
6394 file in silcd/serverconfig.[ch]. It is used to tell whether we
6395 are the initiator to the remote router or whether we'll expect
6396 the other end to connect.
6398 * Moved registering of listener task to silc_server_init, hence
6399 the server starts listenning as soon as it is run, even if it
6400 does not have connections to other routers. Let's see how well
6403 * Changed default connection retry timeouts for more suitable in
6406 * Removed cipher and such arguments from silc_idlist_add_client
6407 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6408 Added new function silc_idlist_add_data to add the keys and stuff
6411 * Added SilcIDListData structure and added it to SilcClientEntry
6412 and SilcServerEntry as their first field in the structure. This
6413 way we can explicitly cast the ID entries to the SilcIDListData
6414 structure and get common data for the entries. In past, we had
6415 to first check what type of connection it is and then cast it to
6416 correct ID entry type. Now, we can directly cast the opaque
6417 pointer to the SilcIDListData (no matter what ID entry it actually
6418 is) and get the data needed.
6420 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6422 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6423 in some circumstances even if threre were timeout tasks, though not
6424 IO tasks, but tasks anyway. Now fixed.
6426 * Defined SilcServerConnection structure to hold connection specific
6427 stuff about directly connected servers and routers. The definition
6428 is currently in silcd/server_internal.h. I thought about having
6429 a bit more important role fro this struct but for now it is used
6430 only when connecting to other server (or router actually).
6432 * Added connecting retry support in server when connecting to
6433 router(s). The retry feature implement exponential backoff
6434 algorithm. Also, added SilcServerParams structure to hold default
6435 parameters for server. For now, it include these retry settings
6436 and are hard coded. After server is moded to be as Silc Server
6437 Library this structure will be more important.
6439 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6441 * Changed client librarys channel->clients table to SilcList and
6442 changed code accordingly.
6444 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6446 * Changed client's channel table to SilcList and changed code
6447 accordingly. Also changed SilcChannelClientEntry to include back-
6448 pointer to the channel so that client entry can use that structure
6449 as list as well and we have fast cross-reference to the channel.
6450 This change dramatically decreased the complexity of channel
6451 handling with client entry and vice versa (removed one extra
6452 loop when searching for channel entry from many functions).
6454 * Changed server->sim from table to SilcDList and changed code
6457 * NAMES command can now be used from user interface. It will show
6458 the user list on the channel, neatly.
6460 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6461 Code now saves realname of the user if it becomes available.
6463 * Renamed configure.in to configure.in.pre and made ./prepare
6464 script to automatically add correct version string to
6465 configure.in which it creates from configure.in.pre.
6467 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6469 * NAMES command reply now shows users mode with the nickname when
6472 * Moved silc_client_ch[u]mode[_char] functions from
6473 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6474 place sucks, they are utility functions and should be in some
6477 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6479 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6482 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6486 * Added TRQ (efficient deque and list library) into lib/trq. This is
6487 a very good list library that is currently used in the SILC. Defined
6488 SilcList API over the library because I didn't like the API very
6489 much. See lib/trq/silclist.h for the API and examples of how to
6490 use the API. Fixed various places in the code to use the new
6491 SilcList API. The SilcList is meant for lists that has a structure
6492 already defined as a list. It is not suitable to add just some
6493 context to the list (in TRQ, the context is the list actually).
6495 So, I defined SilcDList that can be used for the purpose where
6496 predefined list structure does not exit. This can be used as
6497 such list. Now some context just can be added to the SilcDList.
6498 Currently this list is not used in the SILC just yet, though there
6499 are a lot places where this can replace dynamically allocated
6500 tables and I will fix these places, later, to use SilcDList.
6501 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6502 and use TRQ internally).
6504 Also fixed some annoying warning messages that the original TRQ
6505 code generated. Also minor changes to TRQ's Makefile.in.
6507 * Added support for querying by Client ID to both WHOIS and
6508 IDENTIFY commands into server, as required by the protocol.
6510 * Removed method function pointers from SilcBuffer structure. They
6511 weren't used to anything and just increased the context size for
6512 no good reason. This change also made silc_buffer_alloc and
6513 silc_buffer_free functions inline functions.
6515 * Disabled command flooding detection support until it's fixed so
6516 that it accepts commands in but does not execute them more than once
6519 * Added silc_net_localhost(), to return local hostname, into
6520 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6521 that must be initialized before calling silc_client_init.
6523 * Added new function: silc_server_send_notify_on_channels to send
6524 notify messages to all channels client has joined. It is assured
6525 that the message is sent only once per client.
6527 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6528 lib/silcutil/silcutil.[ch] as silc_format function. The new
6529 function is generic and is used by server as well, not only by
6530 the logging routines.
6532 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6533 the provided version string was not acceptable. Added new function:
6534 silc_ske_check_version into lib/silcske/silcske.h. The function
6535 must be implemented by the application (client or server) and it
6536 does not reside in the SKE library. The function checks the version
6537 string remote end sent.
6539 * Added back pointers (to opaque context and to SilcSocketConnection)
6540 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6542 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6543 duplicate packet context structure.
6545 * Changed `notify' client operation to send same arguments as client
6546 receives from server except for ID's. ID's are mapped to correct
6547 ID entry and that is returned. Also, if channel entry is not sent
6548 by server but the notify is for channel the channel entry is sent
6549 to application (otherwise application doesn't know that it is for
6550 channel (library gets it from packet's Destination ID)).
6552 * Added silc_client_remove_from_channels into client library to
6553 remove a client from all channels it has joined to. Used when
6554 received SIGNOFF notify from server. Added also new function
6555 silc_client_replace_from_channels to replace old ID entry with
6556 new ID entry on all channels. Used when received NICK_CHANGE
6559 * Fixed ID Cache list handling in silc_idlist_get_client in
6560 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6561 to get (or query) client by ID.
6563 * Updated TODO list.
6565 * Added connection authentication status message defined by the
6566 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6567 support for these into the code in client and server side.
6569 * Added generic function silc_client_send_command to send any command
6570 with variable argument list. Application should use this function
6571 to send commands if the command functions provided by the library
6572 does not suite for the application's user interface needs.
6574 * Added new `failure' client operation. Application is notified about
6575 received failure packet if client is executing a protocol. In this
6576 case the protocol's execution has failed.
6578 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6579 is required by the protocol.
6581 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6582 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6585 * Added status flag to SilcSKE object to indicate realtime status
6586 of the SKE protocol.
6588 * Application receives now exactly same command reply arguments as
6589 the library receives from server. However, if ID is received the
6590 corresponding ID entry is returned to the application (eg. Client
6591 ID is mapped to correct SilcClientEntry entry and that is returned).
6592 Changed command_reply client operation due to this change.
6594 * Changed all ID's in commands and in command replys as ID Payloads.
6595 Change affected both client and server side codes.
6597 All ID's sent in SILC network (with execption of ID's in SILC
6598 Packet header) are sent in ID Payload to support variable length
6601 * Server now notifies nick changes and notifies all clients on
6602 the channels about the new nickname (about the new Client ID,
6605 * Implemented CMODE command to change channel modes. Supports all
6606 channel modes defined by the protocol specs except ban and invite
6607 lists. (Also, private channel key mode is supported but support for
6608 setting private channel key in client is missing, thus, this mode
6609 has no effect on client side (except that server requires that the
6610 client uses private channel key and normal channel traffic does not
6613 Also, invite mode works per se, but INVITE command does not work
6614 yet correctly, so you can set channel as invite only channel but
6615 inviting clients to the channel does not work (it is yet to be
6616 thought what's the best way to do it).
6618 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6619 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6620 Implemented CUMODE command to change user's mode on the channel.
6621 Supports all modes defined by the protocol specs.
6623 * Added NAMES command reply to return users modes on the channel.
6625 * Removed unnecessary and slow ciphers from lib/silccrypt.
6627 * Set SO_KEEPALIVE option to connection sockets by default.
6629 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6631 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6632 redefined the Notify Payload into protocol specs.
6634 * Added silc_id_payload_parse_id to get ID directly from raw
6637 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6639 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6640 accept searching by Client ID as well.
6642 * Added support for LEAVE and SIGNOFF notify types in client library.
6644 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6645 to parse ID Payload from raw data.
6647 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6649 * Added flags parameter into silc_ske_assemble_security_properties
6650 function in lib/silcske/silcske.[ch].
6652 * Changed notify client operation to fit better for notify messages
6653 sent by server. The notify payload received from server is now
6654 passed to the application (after parsing it to SilcNotifyPayload).
6655 It is application's responsibility to retrieve the arguments
6656 from the payload and show the message the way it wants. The message
6657 sent by server is implementation specific.
6659 * Changed public keys to comply with the protocol specification.
6660 Old public keys are not supported anymore and are not compatible.
6662 * Removed nickname from Channel Payload as the latest draft removed
6663 it. The client must resolve the nickname from the NAMES command
6664 reply received when it joined the channel.
6666 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6668 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6670 * Fixed some errors in protocol specification drafts.
6672 * Created lib/silccore/silcnotify.c to implement Notify Payload
6673 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6674 generic payloads described by protocol specifications. The file
6675 includes implementations for ID Payload and Argument Payload.
6677 * Changed Command Payload implementation to use the new Argument
6678 Payload. Changed command_xxxx_payload to command_payload_xxxx
6679 to comply with SILC coding conventions.
6681 * Added suppport for Argument Payload handling in Notify Payload
6682 implementation as protocol requires it. Added the new support
6683 into server and client lib as well.
6685 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6687 * Added support for multiple nicknames on same channel. [n] is
6688 added locally to the nickname if there are more than one same
6689 nicknames on the channel.
6691 * Server now sends all nicknames that matched WHOIS request.
6692 Client also shows the list received from server.
6694 * Added TOPIC command to client side. User can now set and show
6695 current topic on channel.
6697 * Added MOTD command to client and server. Also, server sends the
6698 motd when client connects to the server.
6700 * Changed version strings to comply ISO 8601.
6702 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6704 * Fixed protocol error handling in client library. It should now
6705 cope even if the SKE fails for some reason.
6707 * Made new protocol specification drafts for submitting to IETF.
6709 * Implemented TOPIC command to server in silcd/command.c.
6711 * Added two new notify types into lib/silccore/silcnotify.h:
6712 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6713 notify nickname change and topic setting/change on a channel.
6715 * API change of command_reply operation in client library. The
6716 application gets now the status type received from server as well.
6718 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6720 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6722 * Cras fixed and optimized the packet handling even further and
6723 it should work now. Minor change to the prototype of function
6724 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6726 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6728 * Added new function into lib/silcutil/silcschedule.[ch]:
6729 silc_schedule_with_fd to select() a specified fd. The function
6730 returns after timeout expires or data arrives or goes. The
6731 function is used by packet routines to wait that all data is
6732 received from network.
6734 * Fixed data reading from network in lib/silccore/silcpacket.c.
6735 The code now assures that all data is read from the fd and then
6736 continues packet processing. This was a bug fix since the code
6737 used to drop some data in some circumstances.
6739 * Added new function into lib/silcclient/client.[ch]:
6740 silc_client_start_key_exchange to start key exchange after
6741 connection has been established to server. The code internally
6742 now uses this funtion but its main purpose was to provide it
6743 for applications that perform their own connecting. After
6744 application has created a connection it merely calls this
6745 function to start the key exchange between client and server.
6746 The library takes care of everything else after that.
6748 Updated also lib/silcclient/README to explain the usage of
6751 * Do not send to application information that connection has
6752 been established. Application gets notified it by connect
6755 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6757 * Applied cras's patch to add silc_schedule_one function. The
6758 function runs scheduler once and returns.
6760 * Fixed the scheduler after cras messed it up. The timeout
6761 handling works now as it's supposed to work.
6763 * Added into lib/silccore/ silcnotify.h to include notify
6764 message types support. Changed silc_server_send_notify*
6765 functions, in server.[ch], to support those new notify types.
6766 Added the support for the notify types into client library,
6767 as well. Added new notify client operation into ops.h in
6770 * Changed silc_server_packet_send_to_channel to send normal
6771 packets instead of just channel message packets. The function
6772 is now used to send the notify packets to channels. It is not
6773 used to send channel message packets anymore, as server never
6776 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6777 va_arg()s as it seems to require it nowadays. I guess, if SILC
6778 is compiled with older va_arg() the new code should work anyway.
6780 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6782 * Splitted core library. Core library (lib/silccore) includes
6783 now only SILC protocol specific core (and common) components.
6784 Created new utility library (lib/silcutil) that includes more
6785 generic purpose stuff. The stuff for util library was taken
6786 from the old core library. This was minor and easy split.
6788 * Created SILC Client Library (lib/silcclient) that includes
6789 implementation of the SILC client without user interface. This
6790 was major move from silc/ directory. The code has been changed
6791 so that it is transparent towards the user interface. The
6792 silc/ directory includes now the same user interface as before
6793 and it uses the new client library. Read lib/silcclient/README.
6794 Basicly, the client library performs everything else related
6795 to SILC except user interface handling. Also, configuration
6796 files are considered to be part of user interface and library
6797 does not handle them.
6799 This change also changed a lot of structures, function naming etc.
6800 Most important change was that SilcClientWindow object was
6801 renamed to SilcClientConnection in the client library. Created
6802 also new file lib/silcclient/ops.h. Also added new files
6803 silc/local_command.[ch] and silc/client_ops.[ch].
6805 All these changes were made to make it easier for user interface
6806 designers to create what ever user interface for the SILC client
6809 It is also expected that the server will be moved to lib
6810 directory as well and SILC Server Library will be created;
6811 sometimes in the future.
6813 * Removed Local commands from lib/silccore/silccommand.h as
6814 they are application specific and new client library does not
6815 handle any of those anymore.
6817 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6818 old client implementation in silc/.
6820 * Added support for callback functions in SILC_LOG_* macros.
6821 Application can now set its own callbacks that will be called
6822 instead of using the default functions that will always print
6823 the debug messages to stderr (or stdout). Also, debugging can
6824 now be disabled by setting silc_debug to FALSE and re-enabled by
6825 setting it to TRUE. Note, that logging will still work even
6826 if debugging is disabled.
6828 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6829 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6830 silc_log_reset_debug_callbacks.
6832 * To enable debugging in silc client one must give now -d
6833 option on command line.
6835 * Changed silc_schedule_init to automatically allocate task queues
6836 if they are not allocated before calling it.
6838 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6840 * Added GMP 3.1 into math library.
6842 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6844 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6845 a channel in SILC network. The packet is used by servers and
6846 routers to notify other routers that user has left a channel.
6847 This little feature was missing until now. Added the feature
6848 to protocol specification as well.
6850 Added functions: silc_server_send_remove_channel_user and
6851 silc_server_remove_channel_user into server.[ch].
6853 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6854 lib/silccore/silcpacket.h. However, they are not implemented
6857 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6859 * Fixed joining to a channel and sending channel messages
6860 between server and router. The channel message sending should
6861 now work inside a cell.
6863 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6865 * Fixed the private message sending between server and router.
6866 The private message sending should now work inside a cell.
6868 * Added silc_server_replace_id into server.[ch] to replace
6869 existing ID in the SILC network.
6871 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6872 and silc_idlist_replace_server_id into idlist.[ch] in server.
6874 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6876 * Fixed the server to server connections. Server can again now
6877 connect to router. Router to router connections probably does
6880 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6882 * Added dynamic protocol registering support. Now protocols can
6883 registered and unregistered on the fly. Patch by cras.
6885 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6887 * Added lib/contrib directory to hold routines that some platforms
6888 don't have but are needed by SILC.
6890 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6891 into lin/contrib to provide getopt() and getopt_long() for
6892 those who don't have it.
6894 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6896 * Added AWAY command to client. When away message is set and
6897 client receives a private message packet the client automatically
6898 replies to the sender with the away message.
6900 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6901 bug seemed to be the cause of recent problems when compiling
6904 * Added version detection support to SKE protocol specification
6905 and added the new changes to the SKE implementation as well.
6906 There were other minor changes in the SKE protocol as well.
6908 Many changes in lib/silcske/silcske.[ch] and in
6909 lib/silcske/payload.[ch].
6911 * Added ^U functionality, clear input line. Patch from cras.
6913 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6915 * Mainly small bugfixes on core library. Fixed some debugging
6916 logging and buffer overflow in silclog.c.
6918 * Updated config.sub and config.guess on the distribution tree.
6920 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6922 * Added command lagging support in server. Client may execute
6923 commands now only once in two seconds.
6925 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6927 * Optimized packet reception. MAC computation and checking is now
6928 also more optimized. A lot previously duplicated code is now
6929 used as generic by both client and server.
6931 * Fixed key pair generation in clientutil.c
6933 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6935 * Added into lib/silccore/silcbufutil.[ch] new function;
6936 silc_buffer_realloc.
6938 * Moved generic packet sending/encryption functions to
6939 lib/silccore/silcpacket.[ch] from client and server. Some
6940 rewriting of the functions.
6942 * Moved all generic packet reception/decryption functions to
6943 lib/silccore/silcpacket.[ch] from client and server. The
6944 packet processing is now much cleaner in both client and server.
6945 These were major changes in both client and server.
6947 * Created many common functions in server to do packet sending.
6948 Previously code were duplicated a lot, this has been removed
6951 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6953 * Rewrote major parts of the ID cache system. Don't know
6954 whether it is better now or not but at least the API is more
6957 * Major rewrite on ID cache stuff on client because of the ID
6958 cache API changes. Added idlist.c to client.
6960 * Also major rewrite on ID cache stuff on server as well.
6961 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6962 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6963 in hand, instead they are all put into the ID cache system now.
6964 All server_idlist_* routines uses ID cache now instead of
6965 traversing its own lists (those lists does not exist anymore).
6966 SilcIDList though still exists. Also, SilcXXXEntry's are
6969 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6971 * Finally made the SKE implementation compliant to the protocol
6972 specification. All mp integers are now binary encoded as
6973 opposed being HEX encoded.
6975 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6978 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6979 functions: silc_[encode/decode]_pem. Also added function
6980 silc_encode_pem_file to PEM encode with newlines ('\n') for
6983 * SILC public keys are now encoded either PEM or binary. Same
6984 option is for private keys as well. By default private keys
6985 are binary encoded and public keys PEM encoded. Silly HEX
6986 encoding were removed.
6988 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6989 function to create fingerprints.
6991 * Fixed a bug in SHA1; does not change the original data anymore.
6993 * Partly implemented INFO command on client and server side.
6994 Fixed CLEAR command. Changes to SERVER command; show current
6995 server(s) when giving command without arguments. Added
6996 VERSION command to client.
6998 * Added check to server that unregistered connections cannot
6999 execute commands (unless it is specificly allowed).
7001 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7003 * Fixed screen refresh.
7005 * Fixed channel joining bug from client. On some circumstances
7006 client tried to join to a channel it had already joined.
7008 * Added public key verification process into client's protocol.c.
7009 The client now verifies the public key from user and saves
7010 it into ~./silc/serverkeys/ directory.
7012 Added into: clientutil.[ch]: silc_client_verify_server_key.
7014 * Changed SKE protocol's silc_ske_initiator_finish function
7015 to accept callback function that verifies the received public
7016 key. Removed old silc_ske_verify_public_key function.
7018 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7020 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7021 silc_pkcs_private_key[_data]_set.
7023 * Made the password and public authentication more cleaner in
7024 server's protocol.c.
7026 * Removed historic and obsolete protocol `channel_auth' from
7027 both client and server.
7029 * Removed wrong way of sending command status messages from
7030 server to client in server's command.c. The old way violated
7031 protocol specification.
7033 Changes to silccore/silccommand.[ch]: removed
7034 silc_command_encode_status_payload -> not needed anymore,
7035 changed silc_command_encode_payload_va to accept extra
7036 argument on variable argument list. The argument type must
7037 now be provided to the function. Also, added new function:
7038 silc_command_encode_reply_payload_va which is same as
7039 normal command_encode_payload_va except command status type
7040 is provided as extra argument.
7042 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7044 * Added ~./silc directory handling. The directory includes the
7045 public and private keys for the client.
7047 Added silc_client_check_silc_dir, silc_client_create_identifier
7048 and silc_client_load_keys.
7050 * Implemented SILC protocol compliant public key. Added public
7051 and private key saving to and loading from files.
7053 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7054 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7055 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7056 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7057 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7059 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7060 silc_pkcs_load_[public/private]_key.
7062 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7064 * Added silc_server_get_route (route.[ch]) to get connection
7065 data for the fastest route for given ID.
7067 * Implemented INVITE command on client and server. The command
7068 were re-defined in the SILC Protocol Specification and the
7069 implementation now complies with the specification.
7071 * Implemented PING command on client and server.
7073 * Implemented NAMES command on client and server. The server side
7074 supports currently only normal server not router server yet.
7075 Some changes to NAMES definition in SILC protocol specification.
7077 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7079 * Implemented LEAVE command on client and server.
7081 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7082 again. This change was made to the protocol as well. Server
7083 should not violate the protocol specification anymore.
7085 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7087 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7088 was tested. SOCKS4 was not but should work anyway.
