1 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Add the client on channel after it was resolved at the
4 channel message receiving, and it was not already on the
5 channel. Affected file lib/silcclient/client_channel.c.
7 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
9 * Fixed the public key authentication to allocate always the
10 destination signature buffer instead of using static buffer.
11 Affected file silcd/protocol.c.
13 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
15 * Unified the serverconfig.[ch]'s helper function interface.
16 Affected file silcd/serverconfig.[ch].
18 * Removed doc/example_silc.conf.in since it is redundant.
19 The make install will now install irssi/silc.conf file.
21 * Added new Passphrase and Publickey authentication methods to
22 config file, allowing both public key and passphrase based
23 authentication to be set at the same time.
25 Added `prefer_passphrase_auth' setting in config file which
26 can be used to set to prefer passwd auth if both passwd and
27 public key is set. If not set, public key is preferred.
28 This has effect only when being initiator (responder will try
31 Added support for authentication with passphrase and public key
32 at the same time. The passphrase is tried first always since
33 it is faster to check.
35 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
37 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
39 * Merged the new SILC Config library, with the server parsing
40 support. Read the header file silcconfig.h or the toolkit
41 documentation for the news. Affected files are

64 Payload. Affected file lib/silccore/silcchannel.c.
66 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
69 * Removed lib/silcclient/README and created HTML file
70 lib/silcclient/silcclient_using.html, which is now included
71 as part of Toolkit documentation.
73 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
75 * Fixed CUMODE_CHANGE notify handling to change the mode of
76 correct client. Affected file lib/silcclient/client_notify.c.
78 * Make silc_rng_alloc fail if it cannot allocate the sha1
79 hash algorithm. Affected file lib/silccrypt/silcrng.c.
81 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
83 * Fixed the file transfer's key agreement payload to include
84 zero port also if the hostname is NULL because it could not
87 Call file transfer monitor callback now also if error occurs
88 during key agreement protocol.
90 Changed the silc_client_file_send interface to return the
91 SilcClientFileError instead of session id. The session ID
92 is returned into pointer provided as argument.
94 Check that the file exists locally before sending the
95 file transfer request at all.
97 Affected file lib/silcclient/client_ftp.c, silcapi.h.
99 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
100 error than can occur while key agreement protocol. Affected
101 file lib/silcclient/silcapi.h.

104 is changed and +k mode is set in the channel. Affected file
105 irssi/src/silc/core/silc-channels.c.
107 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
108 SILC_LOG_WARNING to give out Warning and not Error. Affected
109 file lib/silcutil/silclog.c.
111 * Fixed the channel message payload decryption in the function
112 silc_channel_message_payload_decrypt to not modify the original
113 buffer before it is verified that the message decrypted
114 correctly. Otherwise, next time it is called with correct
115 channel key it won't encrypt since the payload is corrupted.
116 Affected file lib/silccore/silcchannel.c.
118 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
120 * Do not constantly resize the window. A fix patch by cras.

125 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
126 Affected file lib/silcutil/silcnet.c.
128 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
130 * Fixed a bug in hash table internal routine for traversing
131 the table with foreach callback. The current entry may
132 become invalid in the callback but it was referenced after
133 the callback returned.
135 Do not allow auto rehashing of hash table during the
136 silc_hash_table_foreach operation, for same reasons as it is
137 not allowed for SilcHashTableList. Affected files are
138 lib/silcutil/silchashtable.[ch].
140 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
142 * Defined DLLAPI into silcincludes.h and silcwin32.h for

146 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
148 * Fixed private message handling. It used some old code that
149 caused the client to crash. Affecte file is
150 lib/silcclient/client_prvmsg.c.
152 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
154 * Added function silc_client_add_channel,
155 silc_client_replace_channel_id, and removed functions
156 silc_client_new_channel_id and silc_idlist_get_channel_by_id
159 * Added cross reference of the joined channels to the
160 SilcClientEntry, and changed the SilcChannelEntry's
161 users list to SilcHashTable. The affected files are
162 lib/silcclient/idlist.[ch].
164 * Fixed a bug in hash table tarversing. While the hash table
165 is traversed with SilcHashTableList the table must not be
166 rehashed. It is now guaranteed that auto rehashable tables
167 are not rehashed while tarversing the list. Also defined that
168 silc_hash_table_rehash must not be called while tarversing
169 the table. Added function silc_hash_table_list_reset that must
170 be called after the tarversing is over. The affected files are
171 lib/silcutil/silchashtable.[ch].
173 * Changed all hash table traversing to call the new
174 silc_hash_table_list_reset in server and in client library.
176 * Added function silc_client_on_channel to return the
177 SilcChannelUser entry if the specified client entry is joined
178 on the specified channel. This is exported to application as
179 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
181 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
183 * Fixed founder regaining problem with JOIN command on normal
184 server. The notify for mode change must be sent always and
185 not only if !cmd->pending. Affected file silcd/command.c.
187 * Fixed the WHOWAS command's reply sending to support the
188 lists correctly. Affected file silcd/command.c.
190 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
192 * When sending JOIN command to router for processing the
193 sender's old command identifier was not saved back to the
194 sender's command context, fixed now. The affected file is
197 * Create the key in JOIN command of the router did not return
198 the channel key, added check for this. Affected file is
201 * Fixed a channel ID update bug in JOIN command reply. Do
202 not directly upgrade the ID but call the function
203 silc_idlist_replace_channel_id if the ID was changed.
204 Affected file silcd/command_reply.c.
206 * Fixed memory leaks from command calling if it would fail.
207 Affected file silcd/command.c.
209 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

213 Memory leak fixes around libaries, irssi window resize fix,
214 new silclist.h and silcdlist.h, all extern inline changed to
217 * Removed dotconf from lib/dotconf, not needed anymore.
219 * Removed TRQ from lib/trq, not needed anymore.
221 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
222 with server connections. Later this will be configurable
223 in config file after new config file is done. Affected file
226 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
228 * Fixed a crash in server related to channel announcements.
229 Affected file silcd/server.c.
231 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
233 * Fixed memory leaks in silc_server_create_new_channel*
234 functions. Affected file silcd/server.c.
236 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
237 which ID was changed. This way the router will send the
238 user list for the channel again, and server won't be in
239 desync in some rare circumstances. Affected file is
240 silcd/packet_receive.c.
242 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
244 * Check for NULL socket pointer in the function
245 silc_server_packet_send_to_channel_real. Affected file

249 list. Affected file silcd/packet_receive.c.
251 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
253 * Fixed some header addition to Toolkit distribution in
254 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
256 * Added lib/silcclient/client_ops_example.h as an template
257 file for application programmers to quickly start using
258 the SilcClientOperation functions in their application.
259 Updated the lib/silcclient/README as well to tell about this
260 nice file made available.
262 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
264 * Call silc_server_remove_from_channels when removing client
265 entry when NO_SUCH_CLIENT_ID was received. Affected file
266 is silcd/command_reply.c.
268 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
270 * Added server & router operator statistics updating. Affected
271 file silcd/packet_receive.c and silcd/command.c.
273 * Fixed the SERVER_SIGNOFF notify handling on normal server
274 not to save the history information for clients. Same was
275 fixed earlier in remove_clients_by_server function, but not
276 here. Affected file silcd/packet_receive.c.
278 * Raised the default connection-retry count from 4 to 7 in
279 server. Affected file silcd/server.h.
281 * Cancel any possible reconnect timeouts when we start the
282 key exchange. Affected file silcd/server.c.
284 * Do not reconnect on connection failure when SCONNECT was
285 given. Affected files silcd/server.[ch].
287 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
289 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
291 * Fixed the NICK command to always give the unformatted
292 nickname to the one giving the NICK command. If unformatted
293 nickname is cached already it will be formatted and the
294 local entry will always get the unformatted nickname.
295 Affected file lib/silcclient/idlist.c.
297 * Fixed some double frees from client library commands.
298 Affected file is lib/silcclient/command.c.
300 * Fixed CUMODE command in server to assure that no one can
301 change founder's mode than the founder itself, there was a
302 little bug. Affected file silcd/command.c.
304 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
306 * Removed the SilcClientCommandDestructor from the client
307 libary, it is not needed anymore. Affected files are
308 lib/silcclient/silcapi.h, command[_reply].[ch],
309 client_notify, idlist.c.
311 * Fixed GETKEY command to first resolve client, and then
312 resolve the server only if the client was not found, instead
313 of resolving both at the same time. Affected file is
314 lib/silcclient/command.c.
316 * Added silc_client_start_key_exchange_cb and lookup the
317 remote hostname and IP address before starting the key
318 exchange with server. The affected file is
319 lib/silcclient/client.c.
321 * The server's public key is now saved using the IP address
322 of the server and not the servername for the filename.
323 The hostname public key filename is checked as an fall back
324 method if the IP address based filename is not found.
326 Fixed the GETKEY command to save the fetched server key
329 Print the remote server's hostname now when new key is
330 received during connection process. Affected file is
331 irssi/src/silc/core/client_ops.c.
333 * Return always our own public key to the client if it asks
334 for it with GETKEY command. Affected file silcd/command.c.
336 * Removed the use_auto_addr variable from default config
337 file since it was in wrong section. Affected file is
340 * Fixed TOPIC_CHANGE notification to not route it when it
341 was sent using silc_server_send_notify_to_channel function.
342 Affected file silcd/command.c.
344 * Fixed silc_server_send_notify_kicked to send the kicker's
345 Client ID also, it was missing. Affected files are
346 silcd/command.c, silcd/packet_send.[ch].
348 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
350 * Do not save client history information in SERVER_SIGNOFF.
351 Fixes the bug in normal server that it does not detect
352 the client becoming valid after the server becomes back
353 online. Affected file silcd/server_util.c.
355 * Added `sock_error' field into the SilcSocketConnection
356 context. When error occurs during socket operation (read
357 or write) the error is saved. Added also new function
358 silc_socket_get_error to return human readable socket error
359 message. Affected files are lib/silcutil/silcsockconn.[ch],
360 lib/silcutil/unix/silcunixsockconn.c, and
361 lib/silcutil/win32/silcwin32sockconn.c.
363 * The server now prints the socket error message in the
364 signoff for client. Affected file silcd/server.c.
366 * Fixed the `created' channel information sending from router
367 to server in JOIN command. Checks now whether the channel
368 really was created or not and set it according that.
370 Fixed the JOIN command to use the client entry's current
371 ID during the joining procedure instead of the one it sent
372 in the command (it is checked though), since it can change
373 between the packet processing and command processing, and
374 would just case unnecessary pain in the client end. Affected
375 file silcd/command.c.
377 * Fixed a channel key payload sending to use correct channel
378 ID when the server was forced to change the channel's ID by
379 router. Router sent the key payload with the old Channel ID.
380 Affected file silcd/packet_receive.c.
382 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
384 * Call silc_server_save_channel_key only if the key payload
385 was provided in the JOIN command's command reply. Affected
386 file silcd/command_reply.c.
388 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
390 * Fixed silc_mp_sizeinbase to return the value correctly with
391 MPI. Affected file lib/silcmath/mp_mpi.c.
393 * Fixed the stop_server signal to correctly stop the scheduler
394 and gracefully stop the server when SIGTERM or SIGINT signals
395 are received. Affected file silcd/silcd.c.
397 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
399 * Simple handling of TERM and HUP signals. Also added some log
400 flushing call around. Affected file is
403 * Fixed small bugs in silclog.c. Now buffering output will take
404 effect after 10 seconds since startup: This will ensure that
405 no important startup messages are lost. Also output redirection
406 will preserve original format ([Date] [Type] message).
407 Affected file is lib/silcutil/silclog.c.
409 * Added two options to the config file, in the logging section:
410 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
411 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
413 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
415 * Do not print the warning about log files not being initialized
416 more than once to avoid excess logging. Affected file is
417 lib/silcutil/silclog.c.
419 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
420 the SIM copying in make install in Makefile.am.pre.
422 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
424 * Rewritten silclog APIs. Globally interesting changes follows:
425 silc_log_set_files() changed to silc_log_set_file().
426 silc_log_set_callbacks() changed to silc_log_set_callback().
427 ROBOdoc documented silclog header file.
428 SilcLogCb now returns bool to wether inihibit the default
429 handler or not (to keep the old behaviour return always TRUE).
430 The new APIs should also fix the problem of the
431 silcd_error.log file that was written in the current directory.
434 Log files streams will remain opened after silc_log_set_file()
435 call, means less CPU usage notably on high traffic servers.
436 File streams are now full buffered, and flushed to the disk
437 every 5 minutes, lesses HD activity and CPU usage.
438 Messages can be redirected, allowing admins to configure
439 one single logfile for all server messages.
440 the silc_log_quick global variable to activate fast-logging.
441 Affected files lib/silcutil/silclog.[ch]
443 * Changed some code to conform new silclog APIs. Affected
444 files are doc/example_silcd.conf.in, silcd/server.c
445 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
448 * Fixed a memory leak that could occur in some situations.
449 Affected file silcd/serverconfig.c.
451 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
453 * Added the silc_client_del_client to remove the client from
454 all channels as well. Affected file lib/silcclient/idlist.c.
456 * Fixed the client library to correctly remove the client
457 from all channels when the client entry is being destroyed.
458 Affected file lib/silcclient/client_notify.c, command.c.
460 * Added auto-nicking support to the client library. If the
461 applicatio now sets client->nickname it will be sent to the
462 server after connecting by the library. This way for example
463 SILCNICK (or IRCNICK) environment variables will have effect
464 and always change the nickname automatically to whatever
465 it is wanted. Affected file lib/silcclient/client.[ch].
467 * Renamed silc_server_command_bad_chars to the
468 silc_server_name_bad_chars and moved it to the
469 silcd/server_util.[ch]. Added also new function
470 silc_server_name_modify_bad to return nickname that
471 includes bad characters as new nickname without those
472 bad characters. This check and modify is now used in
473 silc_server_new_client when the username is initially set
474 as nickname, so it must be checked to be valid nickname.
475 Affected file silcd/packet_receive.c.
477 * The nickname length is now taken from the packet for real
478 and not trusted to strlen() since it clearly can return
479 wrong length for nickname including bad characters. This
480 also applies to channel names. Affected file silcd/command.c.
482 * Removed the lib/silcsilm/modules directory. Modules are now
483 compiled into the lib/silcsim. Fixed the copying of the
484 modules to follow symbolic links in Makefile.am.pre.
486 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
488 * Fixed silc_string_regexify list creation. Fixes bugs with
489 BAN and INVITE commands in server. The affected file is
490 lib/silcutil/unix/silcunixutil.c.
492 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
494 * Removed the command destructor entirely from the server's
495 command and command reply routines. It is not needed, and
496 its usage was buggy and caused crashes. Affected files are
497 silcd/command[_reply].[ch].
499 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
501 * Cancel protocol and NULL sock->protocol if timeout
502 occurred during protocol. Affected file silcd/server.c.
504 * Cancel protocol timeouts always before calling the final
505 callback, to assure that after final callback is called
506 no other state will be called for the protocol anymore.
507 Affected file silcd/protocol.c.
509 * Print error log if incoming connection configuration could
510 not be found. Affected file silcd/server.c.
512 * Fixed JOIN command to correctly save the founder mode
513 to the client on normal SILC server, when the channel
514 was created by the router. Affected file silcd/command.c.
516 * Fixed LIST command (hopefully) to send correct reply
517 packets. Affected file silcd/command.c.
519 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
521 * The silc_packet_receive_process now returns FALSE if the
522 read data was invalid packet, and TRUE if it was ok.
524 The server now checks that if unauthenticated connection
525 sends data and its processing fails the server will close
526 the connection since it could be a malicious flooder.
528 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
530 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
532 * Make sure the warning about error opening a log file is
533 printed only once and not everytime it fails (produces
534 too much useless log). Affected file lib/silcutil/silclog.c.
536 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
538 * Made the silc_server_daemonise() function more readable.
539 Affected file silcd/server.c.
541 * Pid file is now optional, the user may comment it out from
542 the config file. Removed define SILC_SERVER_PID_FILE, we
543 don't need a default any longer. Affected file
544 configure.in.pre, lib/Makefile.am.pre.
546 * Make some use of the pid file. The server now dies at startup
547 if it detects a valid pid file on his path. The server would
548 die anyway in this circumstance, because of the bind() failure.
549 Affected file silcd/silcd.c.
551 * No longer compiling lib/dotconf.
553 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
555 * Fixed JOIN command parsing not to crash. Affected file
556 lib/silcclient/command.c.
558 * Fied the NICK_CHANGE notify to add the new client entry
559 even it is resolved. This removes an <[unknown]> nick
560 thingy bug in the client. Affected file is
561 lib/silcclient/client_notify.c.
563 * Do not try to allocate 0 bytes (efence does not like it)
564 in lib/silccore/silccomand.c when encoding payload.
566 * Do not take IRCNICK as nickname in Irssi SILC client since
567 it is not possible to set nickname before hand connecting
568 the server (TODO has an entry about adding auto-nicking
571 * Changed the silc_server_command_pending to check whether
572 there already exists an pending entry with the specified
573 command, command identifier and pending callback. This is
574 to fix IDENTIFY and WHOIS related crashes that may register
575 multiple pending commands with same identifier. Affected
576 file silcd/command.c.
578 * Fixed the server to reconnect to the router even if it
579 was already reconnecting and EOF was received. This to
580 fix a possibility that the server wouldn't ever try to
581 auto-reconnect to the router. Affected file silcd/server.c.
583 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
585 * Fixed the server's password authentication to use the
586 length of the locally saved password, and not the one
587 sent in the packet. Affected file silcd/protocol.c.
589 * Fixed same password authentication problem in the
590 Authentication Payload handling routines in
591 lib/silccore/silcauth.c.
593 * Yet another password authentication problem fixed with
594 channel password handling in silcd/command.c.
596 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
598 * If first character of string in silc_parse_userfqdn is '@'
599 then do not parse it. Affected file is
600 lib/silcutil/silcutil.c.
602 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
604 * Fixed minor bug in IDENTIFY command reply sending, which
605 caused various weird problems during JOIN when it was
606 resolving names for users. Affected file silcd/command.c.
608 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
610 * Fixed the IDENTIFY command reply sending to chech better valid
611 clients. It was possible to send incomplete list of replies.
612 Affected file silcd/command.c.
614 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
616 * Added silc_client_command[s]_[un]register functions now to
617 dynamically register the commands in client library. Removed
618 the static table of commands. This allows the client library
619 to call commands without causing the application to know about
620 what commands library has called.
622 Removed the INFO command reply kludge to detect when the command
623 was called by library. Now library use its own command reply
624 function for INFO command.
626 Added function silc_client_command_call to call a command.
627 Application can use it to call command, not access the structure
630 Now all commands that are sent by the client library (not
631 explicitly sent by application) use own command reply functions.
633 Affected files around lib/silcclient/ and in
634 irssi/src/silc/core/.
636 * Fixed the WHOIS command reply sending to chech better valid
637 clients. It was possible to send incomplete list of replies.
639 Fixed the WHOIS and IDENTIFY to send the request to router
640 if normal server did not do it and did not find any results.
642 Affected file silcd/command.c.
644 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
646 * Moved the internal data from SilcClient context into its
647 own file, not accesible to application. Affected files
648 lib/silcclient/client.h and lib/silcclient/client_internal.h,
649 and other files in client library.
651 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
653 * Added doc/examples installation target in Makefile.am.pre.
656 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
658 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
659 commands the found client entry will be removed from the
660 cache, after notifying application about the error. Affected
661 file lib/silcclient/command_reply.c.
663 * Changed the /MSG to check for exact nickname user gave, and
664 not let `nick' match `nick@host' if it is only one found. Now,
665 user must type the exact nickname (like nick@host2) even if
666 there are no more than one same nicks found. This is to avoid
667 a possibility of sending nickname to wrong nickname since
668 `nick' could match `nick@host'. Affected file is
669 irssi/src/core/silc-servers.c.
671 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
673 * Do not print "you are now server operator" or similar when
674 giving /away command. Affected files are
675 irssi/src/silc/core/client_ops.c, silc-servers.h.
677 * Made the silc_server_command_pending_error_check to send
678 the same command reply payload it received back to the
679 original sender of the command. This way all arguments
680 that was received by the server will be received by the
681 client too. Affected file silcd/command.c.
683 * Added the silc_idcache_add to return the created cache entry
684 to a pointer. Affected file lib/silccore/silcidcache.[ch].
686 * Add global clients to expire if they are not on any channel.
687 This is because normal server will never know if they signoff
688 if they are not on any channel. The cache expiry will take
689 case of these entries. This is done by normal servers only.
690 The affected files are silcd/command_reply.c,
691 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
693 * If server receives invalid ID notification for WHOIS or
694 IDENTIFY and the ID exists in the lists, it is removed.
695 Affected file silcd/command_reply.c.
697 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
698 in client then client entry that it matches is searched and
699 the nickname is printed on the screen for user. Affected
700 file irssi/src/silc/core/client_ops.c.
702 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
704 * Use cache entry expire time in the LIST command reply to
705 purge old entries from the cache after the LIST command
706 reply has been received. This way we don't have non-existent
707 entries in the cache for too long. Affected file is
708 silcd/command_reply.c.
710 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
712 * If we are normal server, and we've not resolved client info
713 in WHOIS or IDENTIFY from router, and it is global client,
714 we'll check whether it is on some channel. If it is not
715 then we cannot be sure about its validity and will resolve it
716 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
717 file silcd/command.c.
719 * Search channel by name (if possible) rather than by ID
720 in IDENTIFY command's command reply. Affected file is
721 silcd/command_reply.c.
723 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
725 * Distribute to the channel passphrase in CMODE_CHANGE notify.
726 Updated specs and implemented it. Affected file silcd/command.c,
727 silcd/packet_send.c and silcd/packet_receive.c.
729 * Implemented the <founder auth> payload handling in the JOIN
730 command. If provided all conditions for channel joining
731 except requirement to provide correct passphrase can be
732 overrided by the channel founder. Updated the protocol specs.
733 Affected file silcd/command.c.
735 Added support for founder auth in JOIN command in client
736 library. Fixed the parsing of the JOIN command now to support
737 all options as they should be. The affected file is
738 lib/silcclient/command.c.
740 * Optimized the WHOIS and IDENTIFY commands to send the request
741 to router only if it includes nicknames or other names. If
742 they include only IDs then check the local cache first before
743 routing. Affected file is silcd/command.c.
745 * Added channels topic announcements. Affected file is
746 silcd/packet_receive.c and silcd/server.c.
748 * Fixed the silc_server_send_notify_topic_set to really destine
749 the packet to channel. Affected file silcd/packet_send.c.
751 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
752 library. Affected file lib/silcclient/client_notify.c.
754 * Added UMODE announcements. Affected file silcd/server.c.
756 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
758 * Memory leak fixes in:
760 lib/silcutil/silcsockconn.c
761 lib/silcske/silcske.c
764 lib/silccrypt/silcpkcs.c
765 lib/silccore/silccommand.c
766 lib/silccore/silcidcache.c
771 * ROBOdoc documented the lib/silcske/groups.h file and a
772 bit changed the interface for better.
774 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
776 * Update the client entry context in the ID cache after
777 nick change. Affected file lib/silcclient/command.c.
778 Fixes the CUMODE command when regaining founder privileges,
779 and a little WHOIS problem.
781 * Fixed silc_net_gethostbyname to correctly call the
782 inet_ntop. Affected file lib/silcutil/silcnet.c.
784 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
786 * Added IPv6 support checking to the configure.in.pre, added
787 also --enable-ipv6 option to override the check. Affected
788 file configure.in.pre.
790 * The silc_thread_create now calls the start function
791 directly if threads support is not compiled in. Removes
792 ugly #ifdef's from generic code. Affected files are
793 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
795 * Added silc_net_gethostby[name/addr]_async to asynchronously
796 resolve. Affected files are lib/silcutil/silcnet.[ch].
798 * Added support for rendering IPv6 based server, client and
799 channel IDs. Affected file lib/silcutil/silcutil.c.
801 * Added support for creating IPv6 based server IDs. Affected
802 file is silcd/serverid.c.
804 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
806 * Added silc_net_gethostby[addr/name] into the
807 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
808 routines. Added silc_net_is_ip[4/6]. Affected file is
809 lib/silcutil/unix/silcunixnet.c. All routines that take
810 address as argument now supports both IPv4 and IPv6 addresses.
812 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
814 * Fixed LIST command reply sending in server. Affected file
817 * Server now sends the kicker's client ID in the KICK notify
818 to the kicked client. Affected file silcd/command.c.
820 * The client library now parses the kickers client ID and
821 UI displays it. Affected files lib/silcclient/client_notify.c
822 and irssi/src/silc/core/silc-channels.c, module-formats.c.
824 * Made all payload parsing function prototypes consistent.
825 They all take now const unsigned char * and uint32 pair as
826 the payload data instead of SilcBuffer. Changes all around
827 the source tree. Other unsigned char* -> const unsigned char*
828 changes around the tree as well.
830 * Optimized SFTP client and server packet sending not to
831 allocate new buffer for each packet but to recycle the
832 first allocated buffer. Affected files are
833 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
835 * Optimized the SFTP client to use SilcList instead of
836 SilcDList for requests, because it is faster. Affected file
837 is lib/silcsftp/sftp_client.c.
839 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
840 into lib/silccore/silcid.[ch].
842 Renamed silcpayload.[ch] into silcargument.[ch].
844 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
846 * If client entry is deleted with active key agreement
847 session, abort the session.
849 The silc_client_abort_key_agreement now calls the completion
850 callback with new SILC_KEY_AGREEMENT_ABORTED status.
852 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
855 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
857 * Don't use __restrict in older GCC's. Affected file is
858 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
860 * silc_net_localhost now attempts to reverse lookup the
861 IP/hostname. Affected file lib/silcutil/silcnet.c.
863 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
864 command. It can be used to gain founder privileges at
865 the same time when joining the channel.
867 Defined that the SILC_NOTIFY_TYPE_KICKED send the
868 kicker's client ID as well. Updated protocol specs.
870 Defined that the server must send SILC_COMMAND_IDENTIFY
871 command reply with error status to client who sent
872 private message with invalid client ID.
874 Updated the protocol specification.
876 * Added silc_server_send_command_reply to send any
877 command reply. Affected file silcd/packet_send.[ch].
879 * Added silc_id_payload_encode_data to encode ID payload
880 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
882 * The server now send IDENTIFY command reply with error
883 status if client ID in private message is invalid. Affected
884 file silcd/packet_receive.c.
886 * Save the server key file with server's IP address in
887 the filename instead of hostname. The affected file is
888 irssi/src/silc/core/client_ops.c.
890 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
892 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
895 * Added libtool support for compiling shared objects in
896 lib/silcsim. Affected file configure.in.pre and
897 lib/silcsim/Makefile.am. Original patch by cras.
899 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
901 * Pid file configuration, and server's config file fixes
902 patch by toma. Updated CREDITS file.
904 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
906 * Fixed silc_client_channel_message to not try to decrypt
907 the message twice if it resolved the destination client
908 information. This could cause of dropping one channel
909 message. Affected file lib/silcclient/client_channel.c.
911 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
913 * Added silc_client_run_one into lib/silcclient/silcapi.h and
914 lib/silcclient/client.c. This function is used when the SILC
915 Client is run under some other scheduler, or event loop or
916 main loop. On GUI applications, for example this may be
917 desired to used to run the client under the GUI application's
918 main loop. Typically the GUI application would register an
919 idle task that calls this function multiple times in a second
920 to quickly process the SILC specific data.
922 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
924 * Fixed silc_server_drop() for dropping the supplementary
925 groups as well, this could cause a security hole on some
928 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
930 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
933 * Write PID file after dropping privileges. Added -F option
934 to run server on foreground. A patch by debolaz.
935 Affected files silcd/server.c, silcd/silcd.c.
937 * Fixed MOTD to return the MOTD file server name. Affected
938 file silcd/command.c.
940 * Added INFO command reply handling to the Irssi SILC Client.
941 Affected file irssi/src/silc/core/client_ops.c.
943 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
945 * Fixed the silc_idcache_list_* routines to really support
946 the dynamic list. Fixes a crash. Affected file is
947 lib/silccore/silcidcache.c.
949 * Fixed the LIST command reply to really call LIST command's
950 pending callbacks. Affected file silcd/command_reply.c.
952 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
954 * Update conn->local_entry->nickname after giving NICK
955 command. Affected file lib/silcclient/command.c.
957 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
959 * Added the [pid] option to the silcd configuration file
961 Affected files: serverconfig.[ch] and silcd.c
963 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
965 * Save fingerprint in WHOIS command reply in server.
966 Affected file silcd/command_reply.c.
968 * Fixed NICK commands pending callback registration.
969 Affected file lib/silcclient/command.c.
971 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
973 * Use ++server->cmd_ident when sending commands in server,
974 instead of random number. Affected file silcd/command.c.
976 * Fixed GETKEY command reply to call actually GETKEY pending
977 command callbacks. Affected file silcd/command_reply.c.
979 * A bit stricter check for nicknames. Check for same nickname
980 in NICK command also. Affected file silcd/command.c.
982 * Do not call INFO command everytime client ID changes, only
983 during first connecting. Affected file lib/silcclient/client.c.
985 * Set the new nickname only after successful command reply for
986 NICK command is returned by server. Affected file
987 lib/silcclient/command.c.
989 * Remove nicknames from nicklist during server_signoff notify.
990 Should fix /NAMES bit more. The affected file is
991 irssi/src/silc/core/silc-channels.c.
993 * Added `fingerprint' field to the SilcIDListData in the
994 silcd/idlist.h to hold the fingerprint of the client's
997 Send the fingerprint of the client's public key in WHOIS
1000 Affected files silcd/command.c, and silcd/idlist.[ch].
1002 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1003 create fingerprint from given data.
1005 * Show the fingerprint of the client's public key in WHOIS.
1006 Affected files irssi/src/module-formats.[ch] and
1007 irssi/src/silc/core/client_ops.c.
1009 * Format the multiple same nicknames also during JOIN and
1010 NICK_CHANGE notifys. Affected file is
1011 lib/silcclient/client_notify.c.
1013 * Do not print error on screen for invalid private message
1014 payload since it can come if someone is sending private
1015 messages with wrong key. Affected file
1016 lib/silccore/silcprivate.c.
1018 * Fixed multiple concurrent /PING crash. Affected file
1019 lib/silcclient/command.c.
1021 * Changed the wrong ID encoding. All IP addresses must be
1022 in MSB first order in encoded format. They were encoded
1023 wrong and was in LSB format. Affected files are
1024 silcd/serverid.c, lib/silcutil/silcutil.c.
1026 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1028 * Call the `connect' client operation through the scheduler
1029 in case of error. Affected file lib/silcclient/client.c.
1031 * Call the `failure' client operation even if the error
1032 occurred locally during a protocol. Affected file is
1033 lib/silcclient/protocol.c.
1035 * Added support of sending LIST command to router from normal
1036 server. This way normal server can get list of all channels
1037 in the network too. Fixed the channel list sending in the
1038 server too. Affected files are silcd/command.c, and
1039 silcd/command_reply.[ch].
1041 * Added silc_server_update_channels_by_server and
1042 silc_server_remove_channels_by_server. They are used during
1043 disconnection of primary router and in backup router protocol.
1044 Affected file silcd/server_util.[ch], silcd/server.c and
1045 silcd/server_backup.c.
1047 * Fixed channel adding to global list in IDENTIFY command
1048 reply in server. Affected file silcd/command_reply.c.
1050 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1052 * If the incoming packet type is REKEY or REKEY_DONE process
1053 that packet always synchronously. Fixes yet another MAC
1054 failed error on slow (dialup) connections. Affected file
1055 lib/silcclient/client.c and silcd/server.c.
1057 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1059 * Call check_version SKE callback for initiator too. Affected
1060 file lib/silcske/silcske.c.
1062 * Implemented fix for security hole found in the SKE that was
1063 fixed in the specification few days back; the initiator's
1064 public key is now added to the HASH value computation.
1065 Added backwards support for the old way of doing it too, for
1066 old clients and old servers. Affected file is
1067 lib/silcske/silcske.c.
1069 * Enabled mutual authentication by default in SKE. If initiator
1070 is not providing mutual authentication the responder will
1071 force it. This will provide the proof of posession of the
1072 private key for responder. The affected files are
1073 lib/silcclient/protocol.c and silcd/protocol.c.
1075 * Do not cache anymore the server's public key during SKE.
1076 We do mutual authentication so the proof of posession of
1077 private key is done, and if the server is authenticated in
1078 conn auth protocol with public key we must have the public
1079 key already. Affected file silcd/protocol.c.
1081 * Added new global debug variable: silc_debug_hexdump. If
1082 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1083 file lib/silcutil/silclog.[ch].
1085 * Fixed compilation warning due to char * -> const char *.
1086 Affected files lib/silcutil/silcnet.h, and
1087 lib/silccore/silcauth.[ch].
1089 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1091 * Fixed CMODE command when new channel key was created. If
1092 the creation failed the old key was removed. Next time giving
1093 same command would crash the server since the old key was
1094 freed already. Affected file silcd/command.c.
1096 * Fixed the silc_server_announce_get_channels to not crash
1097 on reconnect. Affected file silcd/server.c.
1099 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1101 * Added silc_log_set_debug_string function to set a regex
1102 string to match for debug output. Only the function names,
1103 or filenames matching the given debug string is actually
1104 printed. This way it is possible to filter out those debug
1105 strings that user is not interested in.
1107 Fixed a bug in silc_string_regexify.
1109 Affected files lib/silcutil/silclog.[ch], and
1110 lib/silcutil/unix/silcunixutil.c.
1112 * Changed the -d options in both server and Irssi SILC client
1113 to take the debug string as argument. Affected files
1114 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1116 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1118 * Added silc_hash_babbleprint to create a Bubble Babble
1119 Encoded fingerprint. The encoding is developed by Antti
1120 Huima (draft-huima-babble-01.txt), and it creates human
1121 readable strings out of binary data. Affected file
1122 lib/silccrypt/silchash.[ch].
1124 * Print the babble print now in addition of fingerprint as well
1125 in Irssi SILC client. Affected files are
1126 irssi/src/fe-common/silc/module-formats.[ch],
1127 irssi/src/fe-common/silc/core/client_ops.c.
1129 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1131 * Fixed a security problem found in SKE. The initiator's
1132 public key too is now added to the HASH hash value creation
1133 which is signed by the responder to create the SIGN value.
1134 This will prevent anyone in the middle to lie to the responder
1135 about the initiator's public key. If this is done now, the
1136 man in the middle will get caught. Updated the protocol
1139 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1141 * Better installation directory handling. Configure module
1142 paths and other paths automatically to example_silc* files
1143 in doc/. A patch by toma.
1145 * Fixed compiler warning from MPI library, and from SILC RNG.
1148 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1149 It can be configured with ./configure. A patch by toma.
1151 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1153 * Find correct make to use in prepare-clean. A patch by
1154 toma. Affected file prepare-clean.

1175 * Added silc_pkcs_public_key_compare to compare two
1176 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1178 * Check that the client who set the founder mode on the
1179 channel is the same client that is giving the founder
1180 mode to itself. It is done by comparing the saved public
1181 key (it is saved even in the authentication is passphrase).

1189 * Process the DISCONNECT packet through scheduler in the
1190 client library. Affected file lib/silcclient/client.c.
1192 * Fixed the silc_client_packet_parse to not to increase
1193 the packet sequence number if the conn->sock and the
1194 current socket connection is not same. This can happen
1195 for example during key agreement when the conn includes
1196 multiple socket connections (listeners). Affected file
1197 lib/silcclient/client.c.
1199 * The sender of the file transfer request now provides also
1200 the pointer (listener) for the key exchange protocol. If
1201 the listener cannot be created then it sends empty key
1202 agreement and lets the receiver provide the listener.
1204 Added `local_ip' and `local_port' arguments to the
1205 silc_client_file_send. If they are provided they are used,
1206 if not then it will attempt to find local IP address, if
1207 not found or bind fails then the remote client will provide
1210 Affected files are lib/silcclient/client_ftp.c and
1211 lib/silcclient/silcapi.h.
1213 * Extended the FILE SEND command to support defining the
1214 local IP and port for key exchange listener. They are
1215 optional. Affected file irssi/src/silc/core/silc-servers.c.

1219 * Defined to WHOIS command reply the sending of fingerprint
1220 of the client's public key (if the proof of posession of the
1221 corresponding private key is verified by the server).
1222 Updated to the protocol specification.
1224 * Added support of receiving the client's public key's
1225 fingerprint in command reply in client library. Affected
1226 file is lib/silcclient/command_reply.c, and
1227 lib/silcclient/idlist.[ch].
1229 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1282 client library. Affected file lib/silcclient/client_prvmsg.c.
1284 * Do not actually remove the client directly from ID cache
1285 during SERVER_SIGNOFF, but invalidate it. This way we
1286 preserve the WHOWAS info for the client. Affected file
1287 silcd/server_util.c.
1289 * Fixed SERVER_SIGNOFF notify handling in the server. The
1290 server is now able to process incoming SERVER_SIGNOFF notify
1291 for a server that it doesn't even know about. It will remove
1292 the clients provided in the notify. Affected file
1293 silcd/packet_receive.c.
1295 * Check for partial packet in data queue after every packet that
1296 was found from the queue. Return and wait for more data if
1297 there is partial data in queue. Affected file is
1298 lib/silccore/silcpacket.c.
1300 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1302 * Added SilcClietFileError enum to indicate error in
1303 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT

1308 * Check that newsize in silc_buffer_realloc is larger than
1309 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1311 * Added better monitor of file transfers. It now monitors
1312 key agreement protocol during the file transfer too. Added
1313 error reporting too. Affected files
1314 irssi/src/silc/core/silc-servers.c,
1315 irssi/src/fe-common/silc/module-formats.[ch].
1317 * Wrote a help file for FILE command.
1319 * Added silc_rng_global_get_byte_fast to get not-so-secure
1320 random data as fast as possible. Random data is read from
1321 /dev/urandom if available and from the SILC RNG if not
1322 available. It is used in padding generation. Affected file
1323 lib/silccrypt/silcrng.[ch].
1325 * All packets in client library are now processed synchronously.
1326 Optimized packet processing a lot. Affected file
1327 lib/silcclient/client.c.
1329 * All server connection packets are processing synchronously
1330 now in server, to optimize packet processing. Affected file
1333 * Include files are installed now only in Toolkit distribution
1334 if make install is given. Affected files: all Makefile.am's.
1336 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1338 * Assure that silc_client_notify_by_server_resolve does not
1339 resolve the client information multiple times. If it cannot
1340 be found by the first it cannot be found at all. Affected
1341 file lib/silcclient/client_notify.c.
1343 * Fixed WHOWAS command reply calling. Affected file
1344 lib/silcclient/command_reply.c.
1346 * Removed all references to silc_idlist_get_client from the
1347 Irssi SILC client since that call is internal call used by
1348 the library. The Irssi SILC client will use now client
1349 retrieval functions found in silcapi.h.
1351 * Fixed a bug in resolving nickname info before sending
1352 private message. It used freed memory. Affected file
1353 irssi/src/silc/core/silc-servers.c.

1374 * Added silc_net_localip to return local host's IP address.
1375 Affected file lib/silcutil/silcnet.[ch].
1377 * If key exchange or rekey protocol is active for a connection
1378 parse all packets syncronously since there might be packets
1379 in packet queue that we are not able to process without first
1380 processing packets before them. Affected file silcd/server,
1381 lib/silcclient/client.c.
1383 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1384 whether library should continue processing the packet.
1385 Affected file lib/silccore/silcpacket.h.
1387 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

1431 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1432 is incomplete and is being resolved, it won't be resolved
1435 Make sure also that USERS command reply does not resolve
1436 twice information. Affected file is
1437 lib/silcclient/command_reply.c.
1439 Make sure that silc_client_get_clients_by_list does not
1440 resolve twice same information.
1442 * Check for valid client->id in the silc_server_free_client_data.
1443 Affected file silcd/server.c.
1445 * Fixed /GETKEY nick@server not to crash if the server entry
1446 is not found. Affected file lib/silcclient/command.c.
1448 * Fixed the silc_server_check_cmode_rights to check the

1456 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1458 * Call the silc_server_udpate_servers_by_server in the
1459 primary router that comes back online in the backup resuming
1460 protocol. Otherwise it routes packets wrong. Affected file
1461 silcd/server_util.[ch], silcd/server_backup.c.
1463 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1465 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1466 lib/silcutil/silcbuffmt.[ch].
1468 * Redefined the SILC packet header to include the padding
1469 length. Affected file lib/silccore/silcpacket.[ch].
1471 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1472 length for maximum padding up to 128 bytes). Affected
1473 file lib/silccore/silcpacket.h.
1475 * Removed all backwards support for old 0.5.x MAC thingies.
1476 The SILC packet header change makes it impossible to be
1477 backwards compatible.
1479 * Send the ENDING packet with timeout in the backup resuming
1480 protocol. This is to assure that all routers has connected
1481 to the primary router. Affected file silcd/server_backup.c.
1483 * Changed the RNG to take the first IV from random data. It
1484 used to take it from zero actually. Changed the RNG also
1485 to use /dev/urandom during session. /dev/random is used
1486 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1488 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1490 * Changed the SILC packet header to have the first two bytes
1491 (the packet length) encrypted. Affected files aroung the
1492 code tree, lib/silccore/silcpacket.[ch]. Removed the
1493 SilcPacketCheckDecrypt callback. It is not needed anymore
1494 since the silc_packet_receive_process will determine now
1495 whether the packet is normal or special.
1497 * Implemented the unidirectional MAC keys. Affected files
1498 lib/silcske/silcske.c, silcd/protocol.c and
1499 lib/silcclient/protocol.c.

1506 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1508 * Allow backup router to announce servers. All servers
1509 announced by backup router are added to the global list
1510 automatically. Update hte server's socket to our primary
1511 router also when backup router announces a server.
1512 Affected file silcd/packet_receive.c.
1514 * Do not update the client->router in the function
1515 silc_server_udpate_clients_by_server if the client is on
1516 global list. We might fail to find any specific server
1517 for locally connected clients and local cell clients. They
1518 should still use the `from' and not `to' as client->router.
1519 This fixes backup router resuming protocol. Affected file
1520 silcd/server_util.c.
1522 * Decrease channel statistics count only if the channel
1523 deletion worked. Affected files are silcd/server.c and
1524 silcd/server_util.c.
1526 * Added silc_server_update_servers_by_server to update origin
1527 of all server entries. Used during backup router protocol.

1533 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1534 lib/silccrypt/silchmac.c.
1536 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1538 * Assure that router cannot reroute the same channel message
1539 to the sender. Affected file silcd/packet_receive.c.
1541 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1543 * Made better checks that the channel message is not sent
1544 to the router it came from. Affected file is
1545 silcd/packet_send.c. Fixed memory leak too.
1547 * Announce informations for incoming router connection, but
1548 only after checking if it is replaced by backup router.
1549 Affected file silcd/packet_receive.c.
1551 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1553 * Fixed the backup resuming protocol to work in multiple
1554 router environment. Affected file silcd/server_backup.c.
1556 * Route packet only to one router in the function
1557 silc_server_packet_send_to_channel. Affected file is
1558 silcd/packet_send.c.
1560 * Fixed silc_server_send_notify_dest to set the broadcast
1561 flag. Fixed the silc_server_send_notify_topic to actually
1562 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1563 Affected file silcd/packet_send.c.
1565 * Changed the SFTP Filesystem interface. Changed the
1566 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1567 the filesystem operation function. The SilcSFTPFilesystem
1568 is now a context that is allocated by all filesystem allocation
1569 functions and it already includes the operations structure
1570 and filesystem specific context. It is given as argument
1571 now to the silc_sftp_server_start. This made the interface
1572 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1573 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1575 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1577 * Changed the backup router adding and getting interfaces
1578 in the server. The router that will be replaced by the
1579 specified backup router is now sent as argument. Affected
1580 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1583 * Added silc_net_addr2bin_ne to return the binary form of
1584 the IP address in network byte order. Affected files
1585 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1587 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1589 * Check for existing server ID in silc_server_new_server
1590 and in silc_server_connect_to_router_final and remove the
1591 old entry if it exists. Affected file silcd/packet_receive.c,
1594 * Send the channel message always to only one router, either
1595 in upstream or downstream. Affected file is
1596 silcd/packet_send.c.
1598 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1600 * Wrote the definition of the backup resuming protocol to the
1601 protocol specification.
1603 * Removed one redundant channel key generation from normal
1604 server during joining procedure. Removed one redundant
1605 channel key sending from server to router during joining
1606 procedure. Affected file silcd/command.c.
1608 * Made minor bugfixes to the backup router resuming protocol.
1609 Affected file silcd/server_backup.c, server.c.

1618 resume the primary router position in the cell after the
1619 primary router comes back online. Affected files
1620 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1621 and silcd/server_util.[ch].
1623 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1625 * Sleep two (2) seconds after sending QUIT command to server.
1626 Affected file lib/silcclient/command.c.
1628 * Assure that if outgoing data buffer is pending do not force
1629 send any data. Affected file silcd/packet_send.c.
1631 * Assure that if outgoing data buffer is pending do not force
1632 send any data. Affected file lib/silcclient/client.c.
1634 * Implemented the backup router support when the primary router
1635 goes down. The servers and routers can now use the backup
1636 router as new primary router without loosing connectivity.
1638 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1640 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1641 in the server to indicate disabled entry. All data read
1642 from the connection will be ignored and no data is sent
1643 for entry that is disabled. Affected files are
1644 silcd/idlist.h, silcd/server.c.
1646 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1648 * Created SFTP client and server test programs in the
1649 lib/silcsftp/tests directory.
1651 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1653 * Implemented memory filesystem (virtual filesystem) for
1654 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1657 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1659 * Implemented the SFTP (SSH File Transfer Protocol) to the
1660 lib/silcsftp. It includes SFTP client and SFTP server
1663 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1665 * Moved lib/silccore/silcprotocol.[ch] to the
1666 lib/silcutil library.
1668 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1669 take variable argument list pointer as argument. Affected
1670 file lib/silcutil/silcbuffmt.[ch].
1672 * Added silc_buffer_set function that is used to set data
1673 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1674 Affected file lib/silcutil/silcbuffer.h.
1676 * Changed various routines in the core library to use the new
1677 silc_buffer_set instead of allocating new buffer only for
1680 * Added 64-bit value formatting and unformatting support to the
1681 silc_buffer_[un]format routines. Affected file is
1682 lib/silcutil/silcbuffmt.[ch].
1684 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1685 to includes/bitmove.h.
1687 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1689 * Fixed channel user mode saving in client library. Affected
1690 file lib/silcclient/command[_reply].c.
1692 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1694 * Defined the file transfer to the SILC Protocol. Added
1695 new packet type SILC_PACKET_FTP and defined File Transfer
1696 Payload. The mandatory file transfer protocol is SFTP
1697 (SSH File Transfer Protocol). Affected file in addition
1698 of the internet draft is lib/silccore/silcpacket.h.
1700 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1701 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1702 is used as part of backup router protocol when the primary
1703 router of the cell is back online and wishes to resume
1704 the position as primary router.
1706 * Redefined the MAC generation keys in the protocol. The
1707 same key is not used anymore in both direction. Both
1708 direction will now use different keys for sending and
1709 receiving. This fixes a potential security flaw. This
1710 change causes incompatibilities in the protocol.
1712 * Redefined also the MAC computation from the packet.
1713 An packet sequence number is now added to the MAC
1714 computation. This prevents possible replay attacks against
1715 the protocol. This change too causes incompatibilities
1718 Added `sequence' field to the SilcPacketContext to hold
1719 the current sequence number for the packet.
1721 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1723 * Added `created' field to the SilcIDListData in the file
1724 silcd/idlist.h to indicate the time when the entry was
1727 * Added `created' field to the SilcChannelEntry too. Affected
1728 file silcd/idlist.h.
1730 * Added `creation_time' aguments to all the announcement functions
1731 in the server. If it is provided then only the entries that
1732 was created after the provided time frame are actually
1733 announced. Affected file silcd/server.[ch].
1735 * The protocol says that the Channel ID's IP address must be
1736 based on the router's IP address. Added check for this in
1737 the silc_server_new_channel when processing incoming New Channel
1738 Payload. Affected file silcd/packet_receive.c.
1740 * Print out the correct version with --version in SILC client.
1741 Affected file irssi/src/silc/core/silc-core.c.
1743 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1745 * Fixed WHOWAS command to check for completnes of the client
1746 entry always, not just when the command is coming from client.
1747 Affected file silcd/command.c.
1749 * Added new function silc_server_packet_queue_purge to purge the
1750 outgoing data queue to the network. After the function returns
1751 it is guaranteed that the outgoing packet queue is empty.
1752 Affected file silcd/packet_send.[ch].
1754 * Purge the outgoing packet queue in the rekey protocol's final
1755 callback to assure that all rekey packets go to the network
1756 before quitting the protocol. Affected file silcd/server.c.
1758 * Added silc_client_packet_queue_parse as similar function as
1759 in server to the client library. The affected file is
1760 lib/silcclient/client.c.
1762 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1764 * Splitted silcd/server.c and created silcd/server_util.[ch]
1765 for utility functions.
1767 * Added new socket flag SILC_SF_DISABLED to indicate that the
1768 connection is open but nothing can be sent to or received from
1769 the connection. Affected file lib/silcutil/silsockconn.[ch].
1770 The checking for disabled socket is checked in the low level
1771 silc_socket_write and silc_socket_read functions.
1773 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1775 * Allow only nicknames and channel names that fits into the
1776 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1778 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1780 * When processing JOIN command reply in server check that if
1781 the channel exists in our global list we'll move it the local
1782 list. Affected file silcd/command_reply.c.
1784 * Fixed the check whether client is joined on the channel already
1785 in JOIN command. Affected file lib/silcclient/command.c.
1787 * Fixed the JOIN command reply to check whether the channel
1788 already exists. Affected file lib/silcclient/command_reply.c.
1790 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1792 * Added silc_ske_status_string to map the SKE error numbers
1793 to readable strings. The affected files are
1794 lib/silcske/silcske[_status].[ch].
1796 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1798 * Do not show the private channels on the WHOIS channel list
1799 as it is not allowed by the protocol. The affected file is
1802 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1804 * Assure that the packet length digged from the actual packet
1805 is something sensible in the silc_packet_decrypt_rest_special
1806 in lib/silccrypt/silcpacket.c.
1808 * Free and NULL the allocated pointer in silc_hmac_alloc if
1809 the HMAC allocation fails. The affected file is
1810 lib/silccrypt/silchmac.c.
1812 * Print the selected security properties to the log files in
1813 the server. Affected file silcd/protocol.c.
1815 * Add SKE's reference counter even if calling the completion
1816 callback manually. Otherwise it goes negative, although it
1817 does not cause any problems. The affected file is
1818 lib/silcske/silcske.c.
1820 * Remove the client entry with short timeout after giving the
1821 KILL command. Affected file lib/silcclient/command.c.
1823 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1824 case all found clients are already disconnected (WHOWAS would
1825 found them) in the server. Affected file silcd/command.c.
1827 * Update the last_receive (time of last data received) to be
1828 updated only when received private or channel message so that
1829 the idle time showed in WHOIS makes more sense.
1831 * Added boolean field `valid' in to the SilcClientEntry in the
1832 client library to indicate whether the entry is valid or not.
1833 This fixes the nickname change bug on channel when changing
1834 the nickname to be same than the old (like nick to Nick) the
1835 nickname formatter doesn't set the new nick anymore to Nick@host.
1836 Affected file lib/silcclient/idlist.[ch].
1838 * Now actually fixed the nickname changing on disconnection.
1839 Added new function silc_change_nick to the Irssi SILC Client.
1840 Affected file irssi/src/silc/core/client_ops.c,
1841 irssi/src/silc/core/silc-nicklist.[ch].
1843 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1845 * Check that the public key exists in the GETKEY command before
1846 trying to encode it. Affected file silcd/command.c.
1848 * Print some notifications on received public keys with GETKEY
1849 command in the Irssi SILC Client. Affected files are
1850 irssi/src/fe-common/silc/module-formats.[ch],
1851 irssi/src/silc/core/client_ops.c.
1853 * Use IDENTIFY command to resolve the server information in the
1854 GETKEY command instead of INFO command. Affected file
1855 lib/silcclient/command.c.
1857 * All command reply functions in the client library now calls
1858 the pending command reply callbacks even if an error has
1859 occurred. The server has done this a long time and now it was
1860 time to move the client library to this as well. Now all
1861 errors can be delivered back to the pending command reply
1862 callbacks if necessary. Affected files are
1863 lib/silcclient/command[_reply].[ch].
1865 * Change the nickname on disconnection back to the username
1866 because in reconnect the server will enforce it to it anyway.
1867 Affected file irssi/src/silc/core/silc-servers.c.
1869 * Fixed a config file parsing bug in the Irssi SILC client.
1870 Affected file irssi/src/silc/core/clientconfig.c.
1872 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * When printing the channel mode on JOIN, verify that the
1875 channel key and channel's HMAC are valid. Affected file
1876 irssi/src/silc/core/client_ops.c.
1878 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1880 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1881 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1882 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1884 * Removed channel key rekey task deleting from the function
1885 silc_server_save_channel_key. Affected file silcd/server.c.
1886 Added explicit timeout task context instead that is used to
1887 delete the task if we are registering a new task before the
1888 new task has elapsed.
1890 * When channel key rekey occurs the client library now saves
1891 the old channel key for a short period of time (10 seconds) and
1892 is able to use it in case some is still sending channel
1893 messages encrypted with the old key after the rekey. Affected
1894 file lib/silcclient/[idlist.h|client_channel.c].
1896 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1898 * Added check to the silc_server_new_id_real to not accept
1899 new ID if it is the sender's own ID. Affected file is
1900 silcd/packet_receive.c.
1902 * Assure that we do not announce ourself or the one we've
1903 sending our announcements when we're router and are announcing
1904 servers to our primary router. Affected file silcd/server.c.
1906 * Fixed silc_server_command_identify_check_client to assemble
1907 correct WHOIS packet. It send corrupted WHOIS packet and
1908 caused problem with router to router connections. Affected
1909 file silcd/command.c.
1911 Fixed also silc_server_command_whois_check the same way
1912 as for the IDENTIFY command.
1914 * Added new SilcIDListStatus to the server in the SilcIDListData
1915 structure. The status now includes the current status of
1916 the entry (like registered, resolved etc.). Affected file
1917 silcd/idlist.[ch]. Defined a bunch of different status types
1918 as well. This replaced the old boolean registered field as well.
1920 Added resolve_cmd_ident field to the SilcClientEntry structure
1921 too so that if the entry is for example being resolved so
1922 another command may attach to the same pending command reply
1923 without requiring to resolve the same entry again. This concept
1924 should optimize the WHOIS and the IDENTIFY resolving under
1925 heavy load by taking away unnecessary resolving for entries
1926 that are being resolved already.
1928 Added support for adding multiple pending commands for one
1929 command idenfier. Affected file silcd/command[_reply].[ch].
1931 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1932 before deleting the data. Otherwise the hash table will have
1933 freed data in comparison functions. Affected file is
1934 silcd/command_reply.c.
1936 * Fixed silc_idlist_replace_client_id to add the new entry to
1937 the cache with NULL nickname. Otherwise there will be invalid
1938 memory as the nickname after the nickname is freed. Affected
1939 file silcd/packet_receive.c.
1941 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1942 saved into wrong slots because the previous number of entries
1943 was not taken into account. Affected file silcd/idlist.c.
1944 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1946 * If we are router and we receive JOIN notify to a channel that
1947 does not have any users then notified client is marked as the
1948 channel founder, as it is it. The affected file is
1949 silcd/packet_receive.c
1951 * Added to the extended hash table API's table_del_*ext functions
1952 the destructor as argument too, so that the caller can decide
1953 which destructor to use or whether to use destructor at all.
1954 Affected file lib/silcutil/silchashtable.[ch].
1956 * Fixed ID Cache purging. It actually deleted the entries from
1957 the hash table after the data was freed. The hash table ended
1958 up comparing freed memory. The affected file is
1959 lib/silccore/silcidcache.c.
1961 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1963 * Fixed Irssi SILC client's KILL command's HELP syntax.
1965 * The USERS command now resolves the detailed user information
1966 if the userinfo field is missing. Affected file is
1967 lib/silcclient/command_reply.c.
1969 * Do not print error in silc_file_read if the read file does
1970 not exist. Just silently return NULL. Affected file is
1971 lib/silcutil/silcutil.c.
1973 * Fixed the silc_log_output to not wine about NULL filename
1974 and to not create some bogus " " filename. Affected file is
1975 lib/silcutil/silclog.c.
1977 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1979 * Fixed various printing bugs on the user interface in the
1980 Irssi SILC Client. Minor changes that were forgotten from
1983 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1985 * Fixed the configure.in.pre and the compilation and distribution
1986 environment to support the new autoconf 2.52. That version is
1987 now required to compile the CVS trunk.
1989 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1991 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1992 to generally parse user@fqdn format strings. Affected file
1993 lib/silcutil/silcutil.c.
1995 * Added nickname_format and nickname_force_format fields to the
1996 SilcClientParams structure. The first one defines the format
1997 for the nicknames that the library will enforce if the receives
1998 multiple same nicknames. The second one is boolean value and
1999 can be used to force the library to always enforce the format
2000 to the nicknames regardles whether there are multiple nicknames
2001 or not. This configurable formatting was employed to flexibly
2002 support accessing multiple nicknames from the user interface.
2003 The userinterface can now set the nicknames to what ever format
2004 they prefer. Affected file lib/silcclient/silcapi.h.
2006 Added function silc_client_nickname_format to the file
2007 lib/silcclient/idlist.c. It performs the nickname formatting.
2009 Added new field `hostname´ to the SilcClientEntry context.
2010 It holds the hostname of the client. Affected file is
2011 lib/silcclient/idlist.h.
2013 * Irssi SILC Client sets the nicknames in nick@hostn format.
2014 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2015 irssi/src/silc/core/silc-core.c.
2017 The WHOIS printing now also shows both the real nickname and
2018 the formatted nickname so that user knows how to access the
2019 user if there are multiple same nicknames cached. Affected
2020 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2021 printing formatting too to take the hostname now as a separate
2022 argument. The Affected file is
2023 irssi/src/fe-common/silc/modules-formats.[ch].
2025 * Changed the silc_client_get_clients_local to accept the formatted
2026 nickname as argument. It accepts the real nickname too but the
2027 formatted nickname can be used to find the true entry from
2028 multiple entries. Affected file lib/silcclient/silcapi.h and
2029 lib/silcclient/idlist.c.
2031 * Added nickname_format_parse field to the SilcClientParams.
2032 It is a callback function provided by the application to parse
2033 the nickname out of the formatted nickname string. The library
2034 calls it to get the nickname from the formatted string. Since
2035 the application generally knows better the format of the nickname
2036 string it parses it instead of the library, even though library
2037 encodes the formatted string. If the callback function is not
2038 provided then the library will use the string as is. The
2039 affected file is lib/silcclient/silcapi.h.
2041 * All the nickname strings passed to the client library in
2042 commands are now expected to be formatted nickname strings.
2043 If the command does not support the formatted nickname string
2044 it will assume that the sent string is the actual nickname.
2045 Affected file lib/silcclient/command.c.
2047 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2049 * Added public key authentication support to OPER and SILCOPER
2050 commands in the client library. Affected file is
2051 lib/silcclient/command.c.
2053 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2055 * Changed the get_auth_methdod client operation to be asynchronous.
2056 It can be async if the application resolves the authentication
2057 method from the server during the negotiation. Added new
2058 SilcGetAuthMeth completion callback that the application will
2059 call after resolving the authentication method.
2061 Added function silc_client_request_authentication_method that
2062 the application can use to resolve the authentication method
2063 from the server. Added also SilcConnectionAuthRequest callback
2064 that the library will call after the server has replied. The
2065 application can call this function if it does not know the
2066 current authentication method.
2068 Affected files are lib/silcclient/client.c and
2069 lib/silcclient/silcapi.h.
2071 * The Irssi SILC client now automatically resolves the authentication
2072 method incase any configuration information is not present (and
2073 currently there never is). The affected file is
2074 irssi/src/silc/core/client_ops.c.
2076 * Fixed public key authentication from the client library.
2077 Affected file lib/silcclient/protocol.c. Changed also the
2078 protocol specification about the public key authentication in
2079 the connection authentication protocol. The actual data to be
2080 signed is now computed with a hash function before signing.
2082 * Fixed the public key authentication from the server as well.
2083 Affected file silcd/protocol.c.
2085 * Removed the mlock()'s from the memory allocation routines.
2086 Affected file lib/silcutil/silcmemory.c. The ./configure does
2087 not check anymore for the mlock(). Affected file is
2090 * Fixed USERS command in server to allow the execution of the
2091 command for private and secret channels if the client sending
2092 the command is on the channel. Affected file silcd/command.c.
2094 * Fixed silc_client_get_clients_local to return the clients
2095 count correctly. It could return wrong value. Affected file
2096 lib/silcclient/idlist.c.
2098 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2100 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2101 types. The assembler optimizations seemed not to like 64-bit
2102 data types. The assmebler optimizations thus are now enabled
2103 also for BSD systems as opposed to only enable them for Linux.
2105 * Do not check for threads at all on BSD systems. Affected
2106 file configure.in.pre.
2108 * Removed -n and -h options from the Irssi SILC Client since
2109 they are not used in silc.
2111 * Fixed the prime generation to assure that the first digit
2112 of the generated random number is not zero since our conversion
2113 routines does not like number strings that starts with zero
2114 digit. If zero digit is seen the random number is regenerated.
2115 This caused some corrupted RSA keys when the zero first digit
2116 was met. Affected file lib/silcmath/silcprimegen.c.
2118 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2120 * Fixed WIN32 configuration in the ./configure script.
2121 Fixed to include xti.h on environments that has it.
2122 Patches by Carsten Ilchmann and andrew.
2124 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2126 * Changed the silc_id_create_client_id to be collision
2127 resistant. It is now assured that there cannot be created
2128 two same client ID's. I suspect that some weird bugs in
2129 the server were actually caused by duplicate Client IDs.
2130 Affected file silcd/serverid.[ch]. A router receiving
2131 new ID now also assures and informs the sending server
2132 if the ID caused collision.
2134 * Changed the silc_id_create_channel_id to also assure that
2135 there are no collisions.
2137 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2139 * Statement about ignoring the Mutual Authentication flag when
2140 performing rekey with PFS was a bit misleading. It is ignored
2141 if it was set in the initial negotiation, it cannot be even
2142 set in the rekey. Fixed in the ke-auth draft. Started the
2143 new versions of the protocol drafts in the doc/.
2145 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2147 * Fixed a bug in silc_client_command_identify_save when saving
2148 new channel information. The channel name was no duplicated
2149 and caused crash on exit. Affected file is
2150 lib/silcclient/command_reply.c.
2152 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2154 * Fixed the getkey command handling in the server. Send just
2155 empty OK reply to the sender if the key could not be fetched
2156 (but everything else was ok, like the key just was not available).
2157 Changed the public key parameter to optional in the protocol
2158 specs so that empty OK reply can be sent. Affected file
2161 Added a message to Irssi SILC client to tell to user if the
2162 server did not return a public key.
2164 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2166 * Fixed a channel key regeneration bug. It registered new
2167 timeout tasks exponentially until all system resources were
2168 used. Affected file silcd/server.c.
2170 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2172 * Added the SILC Document generator to the scripts/silcdoc.
2173 It can be used to generate the Toolkit Reference Manual out
2174 of the source tree. Internally it will also use the RoboDoc
2175 generator now imported in util/robodoc.
2177 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2179 * Added couple of return's in rekey protocol if error orccurred
2180 during the protocol. The execution must be terminated.
2181 Affected file silcd/protocol.c. Also, terminate the protocol
2182 always with timeout.
2184 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2186 * The client's Client ID was created initally from the wrong
2187 nickname (it could have been in format nick@host) in the
2188 silc_server_new_client. Affected file silcd/packet_receive.c
2190 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2192 * Added some SILC_LOG_ERROR's to various error conditions
2193 if client could not be added to ID cache. Affected files
2194 silcd/packet_receive.c and silcd/server.c.
2196 * When client's sock->user_data is freed, NULL also the
2197 client->router and client->connection pointers. Added check
2198 for these pointers being NULL to various places around the
2199 code. Affected file silcd/server.c.
2201 * Added client->data.registered == TRUE checks to various
2202 places around the code to assure that unregistered client's
2203 are not handled when it is not allowed. Affected file
2206 * Added `bool registered' fields to all
2207 silc_idlist_[server|client]_get_* routines to indicate whether
2208 the fetched client needs to be registered or not. Affected
2209 file silcd/idlist.[ch].
2211 * Add your own entry as registered to the ID cache in the
2212 server. Affected file server.c.
2214 * Fixed a bug in silc_server_new_server. The SilcServer was
2215 set as the new server's context instead of SilcServerEntry.
2216 This naturally caused some weird bugs.
2218 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2220 * Do not delete the channel rekey task when adding it
2221 for in silc_server_create_channel_key.
2223 * Changed the silc_server_create_channel_key to return
2224 TRUE or FALSE to indicate the success of the channel key
2227 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2229 * Fixed MSVC++ project files and added missing files to

2232 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2234 * Do not add TCP_NODELAY flag if the operating system
2235 does not have it defined. Affected files are
2236 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2238 * Fixed buffer overflow from Irssi SILC Client. Affected
2239 file irssi/src/fe-common/core/themes.c.
2241 * Fixed double free in client library in the file
2242 lib/silcclient/client.c when disconnecting from server.
2244 * Applied double free patch from cras to Irssi SILC client.
2245 Affected files irssi/src/core/[modules/expandos].c
2247 * Fixed the disconnection handling to Irssi SILC Client.
2248 The application must call silc_client_close_connection
2249 in ops->connect client operation in case of failure of
2250 the connection. Affected file is
2251 irssi/src/silc/core/client_ops.c.
2253 * Do not set sock->protocol to NULL in the function
2254 silc_client_close_connection after executing the protocol's
2255 final callback since the sock might not be valid anymore.
2256 Affected file lib/silcclient/client.c.
2258 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2260 * Do not enable SILC_THREADS if the linking with libpthread
2261 did not happen. Affected file configure.in.pre.
2263 * Added notion to protocol specification that server must
2264 verify the sent authentication payload with CMODE when
2265 setting the channel founder key. Implemented it to the
2266 server. Affected file silcd/command.c.
2268 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2270 * Added _EXTRA_DIST SILC distribution variable to the
2271 distributions file. It is used to conditionally add extra
2272 files or directories to the specific distribution. Affected
2273 files ./prepare, Makefile.am.pre and distributions.
2275 Removed the `_' from the start of the distribution names.
2278 * Added README.WIN32 for instructions to compile the Toolkit
2281 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2283 * Fixed a double free in disconnection in the server. Affected
2284 file is silcd/server.c.
2286 * Fixed the lib/silcske/groups.c to work now also with GMP
2287 MP library. The string conversion did not work when using
2288 specific base and the base is indicated in the string as well.
2290 * Created win32/ directory which now includes MSVC++ specific
2291 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2292 It will appear only in the toolkit distribution
2294 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2296 * Changed the key material distribution function in case when
2297 the hash output is too short. The data is now concatenated
2298 a bit differently than it used to. Made the change to the
2299 SKE protocol specification.
2301 * Added better GMP detection to configure.in.pre. A patch
2304 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2306 * Fixed a minor bug in SKE that might cause some problem on
2307 some platforms. Affected file lib/silcske/silcske.c.
2309 * Added the cookie checking for initiator in the SKE. It checks
2310 that the responder returns the sent cookie unmodified. The
2311 affected file is lib/silcske/silcske.c. Added new SKE
2312 error type INVALID_COOKIE that can be sent during the
2313 negotiation. Fixed some memory leaks as well.
2315 * Added the "invalid cookie" error message to Irssi SILC client's
2318 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2320 * Added `task_max' field to the SilcClientParams to indicate
2321 the maximum tasks the scheduler can handle. If set to zero,
2322 default values are used. Affected file lib/silcclient/silcapi.h.
2324 * Fixed memory leaks in silc_client_close_connection. Affected
2325 file lib/silcclient/client.c.
2327 * Added silc_client_del_client_entry to client library to free
2328 all memory of given client entry. Affected file is
2329 lib/silcclient/idlist.[ch].
2331 * Added new functions silc_client_del_channel and
2332 silc_client_del_server to delete channel and server entries.
2333 Affected file lib/silcclient/[silcapi.h/idlist.c].
2335 * Removed silc_client_del_client_by_id from silcapi.h.
2337 * Fixed the INFO command to return the server's own info
2338 correctly when querying by Server ID. Affected file is
2341 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2343 * Removed the non-blocking settings in WIN32 code in the
2344 silc_sock_[read/write] and added SleepEx instead. Affected
2345 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2346 of input data is now checked with FIONREAD and ioctlsocket.
2348 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2350 * Call silc_schedule_task_del_by_context in the
2351 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2352 Affected file lib/silccore/silcprotocol.c.
2354 * Call silc_protocol_cancel for active protocols in the
2355 silc_server_close_connection if the funtion
2356 silc_server_free_sock_user_data has not been called.
2357 Affected file silcd/server.c.
2359 * Generic tasks cannot be deleted using the del_by_fd
2360 task deleting function since generic tasks does not match
2361 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2363 * Added a notion to SILCOPER help file that the SILCOPER works
2364 only on router server, not on normal server.
2366 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2368 * Added for WIN32 support for the new scheduler as well.
2369 Affected file lib/silcutil/win32/silcwin32schedule.c.
2371 * Fixed the SHA1 implementation to work on various platforms.
2373 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2375 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2376 API. It is part of the scheduler now. Everything else is
2377 as previously but some functions has changed their names.
2378 Checkout the lib/silcutil/silcschedule.h for the interface.
2379 Updated all applications to use the new interface. Affected
2380 files are lib/silcutil/silcschedule.[ch].
2382 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2384 * Found a bug in the SKE implementation. The HASH value,
2385 specified by the protocol, was not computed correctly. The
2386 public key of the responder was not added to the computation
2387 even though it is mandatory. Affected file lib/silcske/silcske.c.
2388 This unfortunately causes incompatibilities with older
2389 clients and servers.
2391 * Added WIN32 specific network init and uninit functions:
2392 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2393 the Winsock2. Affected file lib/silcutil/silcnet.h and
2394 lib/silcutil/win32/silcwin32net.c.
2396 * Set the socket always to nonblocking mode on WIN32 after
2397 reading data or writing data. Affected file is
2398 lib/silcutil/win32/silcwin32sockconn.c.
2400 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2402 * Fixed various compilation problems under WIN32. Affected
2403 files lib/silcutil/win32/silcwin32thread.c and
2404 lib/silcutil/win32/silcwin32schedule.c.
2406 * Removed all _internal.h #includes from public header
2407 files. Internal headers must never be included from
2410 Removed also the lib/silcske/payload_internal.h file.
2412 * All include files that may be needed (public and some others
2413 included by the public headers) by application developers are
2414 now copied to the ./includes directory. It does not copy any
2415 internal headers. Affected file Makefile.defines.pre and all
2416 Makefile.am's under lib/ and subdirs.
2418 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2420 * Do not change the ~/.silc directory's permissions automatically.
2421 Affected file irssi/src/silc/core/clientutil.c.
2423 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2425 * Do not cancel the protocol in silc_server_close_connection
2426 it might cause recursion. Now cancelled in the function
2427 silc_server_free_sock_user_data. Affected file silcd/server.c.
2429 * Fixed the silc_server_remove_clients_by_server to regenerate
2430 the channel keys correctly finally. Added also new function
2431 silc_server_remove_clients_channels to actually do it.
2432 Affected file silcd/server.c.
2434 * Fixed the silc_server_new_channel to not crash by giving
2435 wrong router to the new channel. Affected file is
2436 silcd/packet_receive.c.
2438 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2440 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2441 which is given as argument to the silc_client_alloc now.
2442 It can be used to configure the client and set various parameters
2443 that affect the function of the client.
2445 * The USERS command in server did not check whether the channel
2446 is private or secret. Affected file silcd/command.c.
2448 * Added new argument to the USERS command in protocol specification.
2449 The USERS command now can take the channel name as argument
2450 as well. Added support for this in client and server and
2451 updated the protocol specs.
2453 * Completed the GETKEY command in client. It can be now used
2454 to fetch also servers public key not only some clients.
2455 Affected files lib/silcclient/command[_reply].c.
2457 * Added silc_client_get_server to return server entry by the
2458 server name. Affected files lib/silcclient/silcapi.h and
2461 * Redefined the IDENTIFY command in protocol specification to be
2462 more generic. It now can be used to query information about
2463 any entity in the SILC Network, including clients, servers and
2464 channels. The query may be based either the entity's name
2465 or the ID. Added support for this in both client and server.
2467 Affected files silcd/command.c and lib/silcclient/command.c
2468 and command_reply.c.
2470 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2471 the _from_client and _from_server functions. Affected file
2474 * Added silc_client_get_channel_by_id_resolve to the file
2475 lib/silcclient/silcapi.h to resolve channel information by
2476 its ID. Added also silc_client_get_channel_by_id that
2477 does not resolve it from the server.
2479 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2481 * Added SilcServerEntry context into the client library
2482 to represent one server. The INFO command now allocates
2483 these to save the resolved server info. For now on the
2484 client library will also keep information about servers,
2485 connected and resolved with INFO.
2487 The INFO command now allocates the SilcServerEntry context
2488 and saves the server info there. The COMMAND_REPLY in
2489 the INFO now returns the parameters to application in
2490 same order as defined in the protocol specification.
2492 The entries are cached in the client->server_cache.
2494 * The INFO command is now issued after received the Client ID
2495 from the server. Affected file lib/silcclient/client.c.
2497 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2498 to the application as the mode changer might be server.
2499 It is guaranteed that NULL is not returned anymore to the
2500 application. Affected file lib/silcclient/client_notify.c.
2502 The ID Type is now also passed to the application so that
2503 it can check whether the returned entry is SilcClientEntry
2506 Added new function silc_client_get_server_by_id to return
2507 the server entry by ID. Affected files are the
2508 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2510 * Do not create the channel in the Irssi SILC Client when issuing
2511 the JOIN command but when received the sucessful JOIN command
2512 reply. Otherwise the channel might get created even though we
2513 could not join it. The Affected file is
2514 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2516 * Fixed a channel joining bug in router. The router must also
2517 check the channel modes, invite and ban lists etc. when serving
2518 the JOIN command sent by normal server. Affected file is
2519 silcd/command.c. The router now resolves the client's
2520 information from the server who sent the JOIN command if it
2521 does not know it, and processes the JOIN command only after
2524 * Changed the SilcCommandCb to take new argument; void *context2.
2525 Affected file lib/silccore/silccommand.h
2527 The second argument in the command callbacks in the server now
2528 includes the SilcServerCommandReplyContext if the command was
2529 called as pending command callback from the command reply.
2530 Otherwise it is NULL. When called as pending the status of the
2531 command reply will be checked and if it was erronous the
2532 error will be sent to the original sender of the command.
2533 This way the client always receives the error messages even
2534 though the server was actually the one who received the error
2535 when it resent the command to router, for example. Affected
2536 files silcd/command[_reply].[ch].
2538 * Fixed sending WHOWAS command's error message to client if
2539 the requested client could not be found. It was missing.
2542 * Changed the CMODE and CUMODE commands reply arguments in the
2543 protocol specification. The Channel ID is now sent in both
2544 of the commands to identify the channel. Implemented this
2545 new feature to the client and server. Affected files
2546 lib/silcclient/command_reply.c and silcd/command.c.
2548 * Made better checks for invite and ban lists in the JOIN
2549 command in server. Affected file silcd/command.c.
2551 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2553 * The server now performs the incoming host IP/DNS lookup
2554 using the silc_socket_host_lookup and thus does not block
2555 the server anymore. Affected file silcd/server.c.
2557 * Completed the multi-thread support for SILC Scheduler in
2558 the lib/silcutil/silcschedule.c.
2560 * Fixed the configure.in.pre to detect the pthread correctly
2563 * Fixed a deadlock in silc_task_queue_wakeup in the file
2564 lib/silcutil/silctask.c.
2566 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2568 * Added new function silc_schedule_wakeup that is used in
2569 multi-threaded environment to wakeup the main thread's
2570 schduler. It needs to be used when a thread adds a new task
2571 or removes a task from task queues. After waking up, the
2572 scheduler will detect the task queue changes. If threads
2573 support is not compiled in this function has no effect.
2574 Implemented the wakeup mechanism to both Unix and WIN32
2575 systems. Affected files are lib/silcutil/silcschedule.[ch],
2576 lib/silcutil/unix/silcunixschedule.c and the
2577 lib/silcutil/win32/silcwin32schedule.c.
2579 * Added new function silc_task_queue_wakeup to wakeup the
2580 scheduler by the specified task queue. Affected file
2581 lib/silcutil/silctask.[ch].
2583 * The silc_socket_host_lookup_start now wakes up the scheduler
2584 after adding the timeout task. Affected file is
2585 lib/silcutil/silcsockconn.c.
2587 * The silc_socket_host_lookup is synchronous now if the threads
2588 support is not compiled in. However, the callback is still
2589 called asyncronously through the scheduler, anyway. Affected
2590 file lib/silcutil/silcsockconn.c.
2592 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2594 * Added new function silc_socket_host_lookup to perform
2595 asynchronous IP and FQDN lookups for the socket connection.
2596 Affected files lib/silcutil/silcsockconn.[ch].
2598 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2600 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2601 that may or may not compile the mutex support in.
2603 Changed the silc_mutex_alloc interface. It allocates the
2604 mutex now to the sent pointer and returns TRUE or FALSE.
2606 Affected file lib/silcutil/silcmutex.h.
2608 * Wrote the SILC Task Queue interface to support multi-threads.
2609 Affected file lib/silcutil/silctask.[ch].
2611 * Wrote the SILC Scheduler to support multi-threads. Affected
2612 file lib/silcutil/silcschedule.c.
2614 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2616 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2617 in lib/silcutil/win32/.
2619 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2621 * Defined SILC Mutex API and SILC Thread API and implemented
2622 them for Unix. Affected files are
2623 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2624 lib/silcutil/unix/silcunixmutex.c and
2625 lib/silcutil/unix/silcunixthread.c.
2627 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2629 * Fixed the silc_server_remove_clients_by_server's channel
2630 key re-generation. The hash table handling was incorrect
2631 and would not work with many channels. Affected file is
2634 * Fixed some memory leaks around the server code.
2636 * Rewrote the silc_server_get_users_on_channel to support IPv6
2637 based Client ID's. Affected file silcd/server.c.
2639 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2640 specification. However, a separate document must be written
2641 to define the detailed signing procedure and the payload
2642 associated with the flag. Defined the flag to the
2643 lib/silccore/silcchannel.h as well.
2645 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2647 * Changed the dynamic tables to static size tables in the
2648 lib/silccrypt/silchmac.c.
2650 * Removed GCC dependencies from the code. A patch by cras.
2652 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2654 * Do not show the error "Error receiving packet bla bla"
2655 in server if it really was not an error (-2 means that reading
2656 is pending). Affected file silcd/server.c.
2658 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2660 * Fixed a possible crash in silc_server_remove_clients_by_server
2661 in silcd/server.c. Fixed there also some memory leaks.
2663 * Fixed the silc_idlist_replace_client_id. It could replace
2664 wrong key in the hash table. Affected file silcd/idlist.c.
2666 * Do not check whether there are global users on the channel
2667 if the channel->global_users is FALSE. Affected functions
2668 silc_server_remove_from_one_channel and
2669 silc_server_remove_from_channels in silcd/server.c. Also,
2670 do not check if the removed client is local as we can be
2671 sure that global client was not removed from the channel
2672 and checking for global users is not needed.
2674 * The silc_server_remove_clients_by_server now re-generates
2675 the channel keys correctly for those channels that had
2676 clients removed from them. Affected file silcd/server.c.
2678 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2680 * Found the reason of random crashes in the server. We weren't
2681 ignoring the SIGPIPE signal (which can be sent in write())
2682 and it crashed the server. Affected file silcd/silcd.c.
2684 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2686 * Assure that sock->user_data is not NULL in the function
2687 silc_server_packet_send in silcd/packet_send.c.
2689 * Disconnect the remote connection if it could not be added
2690 to any ID lists in the server. The affected file is
2693 * Check in silc_server_packet_send[_real/dest] that the
2694 socket is not disconnecting and ignore the data if it is.
2695 Affected file silcd/packet_send.c.
2697 * Define inline to __inline on native WIN32 compilation.
2698 Affected file includes/silcwin32.h.
2700 * Added some explicit type casts for inline code since MSVC
2701 require them. Affected files lib/silcutil/silcbuffer.h,
2702 lib/trq/silcdlist.h and lib/trq/silclist.h.
2704 * Print warning in log files from now on if the packet
2705 decryption fails. Affected file silcd/server.c.
2707 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2709 * Changed the `say' client operation's interface to accept
2710 new `type' argument to indicate the type of the message sent
2711 by the library. The application may filter the library's
2712 messages according the type. The affected file is the
2713 lib/silcclient/silcapi.h.
2715 * Added two new functions to lib/silcclient/silcapi.h:
2716 silc_client_del_client and silc_client_del_client_by_id.
2717 Affected file lib/silcclient/idlist.c.
2719 * Moved the clientincludes.h from includes/ to silc/ and
2720 serverincludes.h from includes/ to silcd/.
2722 * The modes for the CMODE and CUMODE are now passed as
2723 uint32 for application with COMMAND_REPLY. The affected
2724 file is lib/silcclient/command_reply.c.
2726 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2728 * /WHOIS without arguments shows client's own information.
2729 Affected file lib/silcclient/command.c.
2731 * Changed PING to not accept any arguments. The specs
2732 says that client can ping only the connected server so
2733 requiring an argument is not needed. Affected file is
2734 lib/silcclient/command.c.
2736 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2738 * Fixed a fatal bug in private message sending and reception
2739 encryption and decryption when using private message keys.
2740 The implementation was incorrect and did not follow the
2741 specification. It causd that some of the message were
2742 lost since it did not use the sending and receiving keys
2743 as the protocol suggests. This has been fixed and will cause
2744 incompatibilities with older clients when sending private
2745 message encrypted with private message keys. Affected files
2746 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2747 and various other in Irssi SILC Client.
2749 Added `responder' boolean argument to the functions
2750 silc_client_add_private_message_key[_ske] to indicate when
2751 the key is added as responder or initiator of the key
2754 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2756 * Removed the silc_ske_check_version function and created
2757 a SilcSKECheckVersion callback. Added also a function
2758 silc_ske_set_callbacks that is now used to set all SKE
2759 callbacks. The callback functions are not given to
2760 the SKE functions anymore, but this function is used to
2763 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2765 * Added `silc_version' argument to the silc_client_alloc
2766 to define the version of the application for the library.
2767 The library will use the version string to compare it
2768 against the remote host's (usually a server) version
2769 string. Affected file lib/silcclient/silcapi.h
2771 * Added the KE protocol context to Key Agreement context
2772 in client library so that we can abort the SKE if it
2773 is in process when we get timeout. Affected file is
2774 lib/silcclient/client_keyagr.c.
2776 * Do not resolve the client ID forever if it returns in the
2777 first time that such client does not exist. This was done
2778 for example with private message. Affected file is
2779 lib/silcclient/client_prvmsg.c.
2781 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2783 * Do not add regex.h for WIN32. The affected file
2784 includes/silcincludes.h.
2786 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2787 not work yet 100%. It generates the DLL's automatically
2788 when compiling with --with-win32 under cygwin.
2790 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2792 * lib/contrib/regex.c is not compiled on WIN32.
2794 * Added silc_net_get_socket_opt function to the
2795 lib/silcutil/silcnet.h.
2797 * Added includes/silcwin32.h for WIN32 specific includes
2800 * Do not use ptime structure or any of the posix process
2801 functions on WIN32 in lib/silccrypt/silrng.c.
2803 * Added silc_gettimeofday to provide generic function
2804 for struct timeval on all platforms. Added the function
2805 to lib/silcutil/silcutil.h.
2807 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2809 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2810 library as they clearly belong there. As a plus side we
2811 can make the actual socket connection routines platform
2814 Added also new generic function silc_socket_read and
2815 silc_socket_write (that used to be silc_packet_[read/write].
2816 The implementation of these are platform specific.
2818 * Added WIN32 specific routines of silc_socket_[read/write]
2819 to lib/silcutil/win32/silcwin32sockconn.c.
2821 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2823 * Added preliminary support for native WIN32 compilation under
2824 cygwin (using the -mno-cygwin option for GCC) to the
2825 ./configure.in.pre. The --with-win32 now prepares the
2826 compilation for native WIN32.
2828 * Rewrote the SILC Scheduler interface in the file
2829 lib/silcutil/silcschedule.h. The scheduler is now context
2830 based and does not have anymore any global static scheduler.
2831 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2832 and created lib/silcutil/win32 directory for WIN32 based
2835 * Added Unix specific network routines to the
2836 lib/silcutil/unix/silcunixnet.c and the old
2837 lib/silcutil/silcnet.c includes now only generic routines.
2839 Added WIN32 specific network routines to the
2840 lib/silcutil/win32/silcwin32net.c.
2842 * Added Unix specific utility functions from the
2843 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2845 * Added WIN32 SILC Scheduler to the file
2846 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2849 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2851 * Do not handle JOIN notify in the server if the target client
2852 is not registered (idata->registered == FALSE). The affected
2853 file is silcd/packet_receive.c.
2855 * Update the nickrec->founder in event_cumode in the Irssi SILC
2856 client. Affected file irssi/src/silc/core/silc-channels.c.
2858 * Fixed the CUMODE_CHANGE notify handling in the server when
2859 server and router are announcing their clients on channels.
2860 Now the mode changes are saved and notified correctly. The
2861 affected file is /silcd/packet_receive.c.
2863 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2864 They really did not replace the cache entry in the ID Cache.
2865 Now they do that. Affected file silcd/idlist.c.
2867 * Fixed the KICK notify handling in the Irssi SILC client to
2868 update the channel records so that the kicked client does not
2869 appear to be on the channel. The affected file is
2870 irssi/src/silc/core/silc-channels.c.
2872 * Always update the conn->current_channel when executing command
2873 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2875 * Fixed the KILL notify handling in Irssi SILC client to remove
2876 the killed client on all channels.
2878 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2880 * Fixed the silc_parse_command_line to remove extra spaces
2881 from the start and end of the arguments. Affected file is
2882 lib/silcutil/silcutil.c.
2884 * Cancel and free any active protocol in the function
2885 silc_server_close_connection. Affected file silcd/server.c.
2887 * Cancel and free any active protocol in the function
2888 silc_client_close_connction. Affected file is
2889 lib/silcclient/client.c.
2891 * Do not execute the KILL command for clients that are in
2892 history (ie. they are not in the network). Affected file is
2895 * Fixed KILL notify handling, client does not crash anymore.
2896 Affected file irssi/src/silc/core/silc-channels.c.
2898 * Reduced the default packet buffer size from 2048 to 1024 in
2899 lib/silccore/silcpacket.c.
2901 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2902 counter to the SKE context that is incresed when the SKE library
2903 performs async operation outside the library. If the outside
2904 process frees the SKE context and FREED status will be set
2905 and the library will detect after the sync operation that the
2906 libary is freed. The affected files are
2907 lib/silcske/silcske[_status].[ch].
2909 * Resolve the client entry information in the function
2910 silc_client_channel_message to assure that NULL pointer is not
2911 passed as client entry to the application. */
2913 * Fixed the task timeout calculation to assure that there is
2914 never negative timeouts. The affected file is
2915 lib/silcutil/silcschedule.c.
2917 * Fixed the channel user mode notification sending in server.
2918 It was sent point-to-point to the router (or to server by router)
2919 but it needs to be destined to a channel. The routines now
2920 supports sending the channel user mode notifys to the channels
2921 when announcing clients and channels. Affected files are
2922 silcd/server.c and silcd/packet_receive.c.
2924 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2925 It did not actually replace the old channel entry in the cache.
2926 Affected file lib/silcclient/client_notify.c.
2928 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2930 * Fixed a possible crash in silc_packet_send_prepare. It now
2931 assures always that there is enough space in the buffer and
2932 at the tail area of the buffer (for MAC).
2934 Fixed the inbound buffer reallocation in silc_packet_read.
2935 It was old code and did not handle the reallocation correctly.
2938 The affected file is lib/silccore/silcpacket.c.
2940 * Fixed buffer overflow in silc_parse_nickname in the file
2941 lib/silcutil/silcutil.c.
2943 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2945 * make install generates new server keys only if there is not
2948 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2950 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2951 Added check that if the NOREPLY is set then we will not send
2952 the away message. This avoids infinite loop of away messages
2953 if both clients are away. The affected file is
2954 lib/silcclient/client_prvmsg.c.
2956 * Fixed client crash if /NICK was given without arguments.
2957 Affected file lib/silcclient/command.c.
2959 * Server does not send the invite list in INVITE command back
2960 to the client if the list was not altered. Added this notion
2961 to the protocol spec as well. Affected file silcd/command.c.
2963 Fixed possible crash in INVITE command by checking the
2964 value of silc_server_get_client_route command.
2966 * Fixed the INVITE notify type handling. The arguments are now
2967 taken in correct order and client does not crash. The affected
2968 file is irssi/src/silc/core/silc-channels.c.
2970 Removed the "Inviting xxx to channel" message from the
2971 client library away and let the application handle it.
2972 Affected file lib/silcclient/command.c. Added that message
2973 to Irssi SILC client's message formats.
2975 * Fixed CMODE command crash in client. It now checks the
2976 amount of arguments correctly and does not crash. The affected
2977 file is lib/silcclient/command.c.
2979 * Do not create new channel automatically in silc_channels_join
2980 but check whether the channel by that name already exists.
2981 Affected file irssi/silc/core/silc-channels.c.
2983 * Do not send the SERVER_SIGNOFF to router if the disconnected
2984 entity was the router. Affected file silcd/server.c.
2986 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2987 SILC client as it was missing from there.
2989 Added the handling of the KICK notify to the Irssi SILC client
2990 as it was missing. Added "you have been kicked" message to
2991 Irssi SILC client's message modules formats.
2993 Added the handing of the KILL notify to the Irssi SILC client
2994 as it was missing. Added the kill message module formats
2997 The affected file is irssi/src/silc/core/silc-channels.c.
2999 * The router did not save the channel mode the server announced.
3000 Affected file silcd/packet_receive.c.
3002 * Fixed a possible crash in INFO command in server. If the
3003 server did not provide the server info it crashed. Affected
3004 file silcd/command.c.
3006 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3008 * Fixed the GETKEY command in the server to check also the
3009 global list. Otherwise the GETKEY would not work correctly
3010 in normal SILC server. Affected file silcd/command.c.
3012 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3014 * Fixed GETKEY crash, it crashed if the command did not succseed.
3016 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3018 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3019 is now real and not just an macro interface to GMP.
3021 Removed the entire GMP from the source tree and imported new
3022 NSS MPI library instead. Reason for removing GMP is that it is
3023 extremely large and compiles extremely slow. The NSS MPI
3024 is only a few files and compiles in less than 10 seconds.
3025 The speed is also about the same as GMP. The MPI is imported
3026 to lib/silcmath/mpi.
3028 If the system has GMP installed we will still use the GMP.
3029 If it is not then the NSS MPI will be compiled.
3031 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3033 * Merged a long nickname (127 characters long) crash bugfix from
3034 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3036 * Merged a freed memory reference bugfix from Irssi CVS tree.
3037 Affected file irssi/src/core/commands.c.
3039 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3041 * Added the server's public key sving and verification to the
3042 server when performing the SKE. This was missing and the
3043 remote server's (or router's) public key was accepted without
3044 checking whether we have it previously or trust it at all.
3045 Affected file silcd/protocol.c.
3047 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3049 * Check in the silc_server_timeout_remote if protocol is active
3050 and make sure that the protocol's final callback is called so
3051 that all memory if freed. Affected file silcd/server.c.
3053 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3055 * silc_server_whois_send_reply crashed the server if the nickname
3056 was 127 characters long. Affected file silcd/command.c.
3058 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3060 * Added sanity check to the silc_server_new_client. If the hostname
3061 is provided inside username then check that the provided hostname
3062 really is the same as the resolved one. If the hostname was not
3063 resolved then check it from the public key. Affected file is
3064 silcd/packet_receive.c.
3066 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3067 if the server disconnected us and the connection is not valid
3068 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3070 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3071 the library to the lib/silcutil/silcutil.[ch].
3073 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3075 * Close log file after open. Affected file
3076 lib/silcutil/silclog.c.
3078 * Check whether sock == NULL in silc_client_send_packet and return
3079 if it is. Affected file lib/silcclient/silcclient.c.
3081 * Check rec->entry == NULL in the Irssi SILC Client before
3082 sending the channel message. Affecte file is
3083 irssi/src/silc/core/silc-servers.c.
3085 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3087 * Merged a splitted window bugfix from Irssi CVS tree. The
3088 affected file is irssi/src/fe-text/textbuffer-view.c.
3090 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3091 It did not print nickname.
3093 * Improved the distributions system a bit.
3095 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3097 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3098 irssi/src/fe-text/gui-window.c.
3100 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3101 to in-active server. The affected file is
3102 irssi/src/silc/core/client_ops.c.
3104 * Resolve the client in USERS command reply if the entry does
3105 not have username resolved. The affected file is
3106 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3107 command to WHOIS command to really resolve stuff. The USERS
3108 is not used any more in any critical section so WHOIS can
3109 be used even though it might be slower than IDENTIFY.
3111 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3114 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3116 * Changed the protocol API a bit more consistent in the
3117 lib/silccore/silcprotocol.[ch].
3119 * Changed the following headers to ROBODoc format:
3121 lib/silccore/silcpayload.h
3122 lib/silccore/silcprotocol.h
3123 lib/silccore/silcsockconn.h
3125 All core library headers are now formatted.
3127 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3129 * Fixed a bug in Irssi SILC client; do not show that you are
3130 server/router operator if you really are not. Affected file is
3131 irssi/src/silc/core/client_ops.c.
3133 * Renamed silc_command_free_payload to silc_command_payload_free.
3134 Affected file lib/silccore/silccommand.h
3136 * Added silcmath.h to include the prototoypes of various routines
3137 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3140 * Changed the following headers to ROBODoc format:
3142 lib/silccore/silcchannel.h
3143 lib/silccore/silccommand.h
3144 lib/silccore/silcid.h
3145 lib/silccore/silcidcache.h
3146 lib/silccore/silcmode.h
3147 lib/silccore/silcnotify.h
3148 lib/silccore/silcpacket.h
3149 lib/silcmath/silcmath.h
3151 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3153 * Added checking to the server code not to start the server if
3154 ciphers and stuff are not configured properly. Affected files
3155 silcd/serverconfig.[h] and silcd/server.c.
3157 * Changed the layout of the header files of the public interfaces
3158 in the SILC libraries. The new layout supports ROBODoc
3159 documentation tool (and some others) so that it is easy to create
3160 a library reference manual. All the other headers and source
3161 code must still follow the CodingStyle document. Also source
3162 code must not include these ROBODoc stuffs, only the headers.
3163 Furthermore, all public interface headers must now be named
3164 by using `silc' prefix, example: silcapi.h, silccipher.h.
3165 Some files were renamed due to this. All the other headers
3166 must not be used as public interfaces. I will update the
3167 CodingStyle document later. Changed following headers, so far:
3169 lib/silcclient/silcapi.h
3170 lib/silccore/silcauth.h
3171 lib/silccore/silcprivate.h
3172 lib/silccrypt/silcdh.h
3174 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3178 * Removed silc_client_packet_send_flush from the client library
3179 as it is not needed. Affected file lib/silcclient/client.[ch].
3181 * Added printing of message of unresolved authentication method
3182 to the Irssi SILC client. Added it to the module formats.
3183 Removed the same message from the client library.
3185 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3187 * Added new distribution feature, DISTLABEL. Every distribution
3188 can define own preprocessor label that can be used in the
3189 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3190 file distributions, acconfig.h.pre and prepare.
3192 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3194 * Added Makefile.defines_int to include the actual definitions
3195 for Makefile.defines.in. Tested the new distribution system,
3196 created distributions and tested installation.
3198 * Added AWAY message printing to the Irssi SILC client. Added
3199 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3201 * Added SCONNECT command to call the SILC's CONNECT command.
3202 Cannot use CONNECT directly since Irssi uses that internally.
3203 Affected file irssi/src/silc/core/silc-servers.c.
3205 Added ACTION local command. It is same as ME command but takes
3206 the channel as mandatory argument.
3208 Rewrote some of the Irssi's help files to suite for SILC
3211 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3213 * Added Makefile.defines[.in] that should for now on be included
3214 in all Makefile.am file in the source tree. That file includes
3215 all common compilation definitions for SILC source tree.
3217 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3219 * Minor changes to the ./prepare script to change the package
3220 name according the distribution name to the configure.in.
3222 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3224 * Created new distribution system. Added file `distributions'
3225 that defines all the distributions that can be created out of
3226 the SILC source tree. The ./prepare script now reads that
3227 file to determine how to prepare the distributions. The
3228 first argument to the ./prepare is the name of the distribution
3229 and second is the version of the distribution. If given
3230 without arguments it creates the default (toolkit) distribution
3231 with the default version (defined in ./prepare).
3233 All Makefile.am files that are subject to the distributions
3234 are now named as Makefile.am.pre. These are ./Makefile.am
3235 and lib/Makefile.am. Others may be changed later.
3237 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3239 * Added invite list, ban list, some key management and connection
3240 error message printing to module formats in the Irssi SILC client.
3242 * Added new silc_client_set_away_message to set the away message
3243 that is back to the person who sent private message. The
3244 affected file lib/silcclient/silcapi.h and the
3245 lib/silcclient/client_prvmsg.c.
3247 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3249 * Fixed the private message sending in the Irssi SILC client,
3250 added local command KEY to the Irssi SILC client.
3252 Added key management and key agreement message formats to the
3253 irssi/src/fe-common/silc/module-formats.[ch].
3255 Added USERS (alias WHO) printing, server/router operator
3256 indication and LIST command printing to the module formats.
3258 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3260 * Fixed channel joining notify handling, cumode notify handling
3261 from Irssi SILC client.
3263 * Added SILC specific module-formats to the Irssi SILC client so
3264 that SILC specific message hilighting, colors etc is possible.
3265 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3267 Added channel mode, channel user mode, actions, notices,
3268 whois and whowas printing to the the module-formats.c.
3270 * Fixed a bug in channel deletion in the server. The channel
3271 is not left to the cache even if the channel founder auth mode
3272 is set when there are no users anymore on the channel. Affected
3273 file silcd/server.c.
3275 * The silc_net_localhost now resolves the entire hostname including
3276 the domain name. Affected file lib/silcutil/silcnet.c.
3278 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3280 * Changed the ask_passphrase client operation to be ascynchronous.
3281 It has now a completion callback and a context that the
3282 application must call after it has got the passphrase from
3283 the user. Affected files lib/silcclient/silcapi.h,
3284 lib/silcclient/protocol.c, lib/silcclient/command.c and
3287 Added SilcAskPassphrase callback that the application calls
3288 to deliver the passphrase to the library.
3290 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3291 The public key verification and especially a certificate
3292 verification is asynchronous procedure.
3294 Added new SILC_SKE_STATUS_PENDING status to indicate the
3295 request is pending and a callback will be called to finalize
3298 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3299 indicate that remote end did not send its public key (or
3300 certificate), even though we require it. Added check for this
3301 condition in the SKE. This was a security bug, now fixed.
3303 Defined new SilcSKEVerifyCbCompletion callback that is called
3304 when the verification process is completed.
3306 The affected files lib/silcske/silcske_status.h and
3307 lib/silcske/silcske.[ch].
3309 * Changed the verify_public_key client operation to be async
3310 as well. Defined SilcVerifyPublicKey callback that is used to
3311 indicate the success of the public key verification process.
3313 Changed the server and client to use the new async client
3316 * Changed the Irssi SILC client's internal scheduler to be called
3317 twice as many times as it used to be. As a result the client
3318 should be a bit faster now. Affected file is
3319 irssi/src/silc/core/silc-core.c.
3321 * Added support to Irssi SILC client of asynchronous public key
3322 verification and passphrase inquiry. Affected file is
3323 irssi/src/silc/core/silc-core.c.
3325 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3327 * Do not say "You have left channel %s" in client library.
3328 Moved it to the application. Affected files are
3329 lib/silcclient/command.c and silc/client_ops.c.
3331 * Fixed silc_client_get_clients. Command context was not
3332 duplicated and was freed memory in the callback. Affected
3333 file lib/silcclient/idlist.c.
3335 * Do not say "you are now talking..." on JOIN command in the
3336 client library. The appliation must handle it.
3338 * Do not say ".. changed topic to" in command reply in the
3339 client libary. The application must handle it.
3341 * Fixed TOPIC command sending in the client library.
3343 * Fixed a memory leak in silc_client_command_free in the file
3344 lib/silcclient/command.c.
3346 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3348 * Imported a modified version of Irssi client to the source tree.
3349 The Irssi will be used to create a new client called
3350 Irssi SILC. Imported to irssi/.
3352 Added silc_core_init_finish function to the Irssi. Affected
3353 file irssi/configure.in.
3355 A lot changes in the Makefile.ams around the irssi tree.
3357 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3359 * Do not rehash if the new size is same as the old size of the
3360 hash table, in the silc_hash_table_rehash*. The affected file
3361 lib/silcutil/silchashtable.c.
3363 * Replaced hash_table_del_by_context calls from the server
3364 (when channel->user_list and client->channels) to the
3365 hash_table_del as it is sufficient and faster.
3367 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3369 * Added silc_hash_table_list, silc_hash_table_get and the
3370 SilcHashTableList structure to provide an alternative way to
3371 traverse the hash table. The affected files are
3372 lib/silcutil/silchashtable.[ch].
3374 * Changed the server's idlist routines to use the hash table
3375 routines to optimize the code.
3377 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3379 * Replaced the client entry's `channel' list and channel entry's
3380 `user_list' list to hash tables for optimized lookup. Changed
3381 the code to use the hash table interface around the code.
3382 Affected file lib/silcd/idlist.[ch].
3384 * Added `auto_rehash' boolean argument to the function
3385 silc_hash_table_alloc to indicate whether the hash table should
3386 auto-rehash when it thinks is appropriate time. It will
3387 increase the hash table size if the there is twice as much
3388 entries in the table than the size of the table, and will
3389 decrease the size if there are twice as less entries than
3390 the size of the table.
3392 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3394 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3396 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3398 * silc_idcache_purge_by_context deletes the entry now by context
3399 as it is supposed to do. Affected file lib/silccore/idcache.c.
3401 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3402 client is not anymore valid (WHOWAS givens the info) and not
3403 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3405 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3407 * Removed the `data' and `data_len' arguments from the ID Cache
3408 interfaces and added `name' argument. ID Cache does not handle
3409 anymore the binary data only a names associated with given ID.
3411 * When hashing a Client ID with silc_hash_id the entire ID is
3412 not hashed anymore, instead only the hash of the Client ID is
3413 hashed. This way we can access the Client ID from the cache
3414 with Client ID but with the hash of the ID (which is a hash of
3415 the nickname) as well without any difference in performance.
3417 Added also silc_idcache_find_by_id_one_ext to do one on one
3418 searching when we have the actual ID. Added also function
3419 silc_hash_client_id_compare. The affected files are
3420 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3422 * When hashing the name associated with a ID it is always done
3423 in lowercase. This way we can access the cache without worrying
3424 about case-sensitivity, even though, for example nicknames are
3427 * Fixed a bug in server with channel message sending. It put
3428 wrong ID type as destination ID. The affected file
3429 silcd/packet_send.c.
3431 * silc_idcache_del_by_context now deletes from all hash tables
3432 by context. Affected file lib/silccore/idcache.c.
3434 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * Changed the client library to use the new ID Cache interface.
3437 Changes around the source tree.
3439 * Added silc_hash_table_rehash_ext to rehash with specific
3440 hash function. Affected file lib/silcutil/silchashtable.[ch].
3442 * Added silc_hash_string_compare to compare two strings in the
3443 hash table. Affected file lib/silcutil/silcutil.[ch].
3445 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * Added new function silc_idcache_del_by_context into the
3448 lib/silccore/idcache.[ch].
3450 * Changed the server's ID list routines to use the new ID Cache
3451 interface. Changes around the source tree.
3453 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3455 * Added silc_hash_table_del[_by_context]_ext functions in to the
3456 lib/silcutil/silchashtable.[ch].
3458 Removed silc_hash_table_find_all* routines and added new
3459 silc_hash_table_find_foreach to replace them.
3461 Added silc_hash_table_replace_ext function as extended
3462 replacing function. Separated the simple hash table interface
3463 from the extended hash table interface in the file
3464 lib/silcutil/silchashtable.h.
3466 * Fixed minor bugs and changed it to use some of the new
3467 hash table functions in lib/silccore/idcache.c
3469 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3471 * Added new function silc_hash_table_find_all to return all keys
3472 in the hash table by the specified key. As the hash table is
3473 collision resistant it also makes it possible to have several
3474 duplicate keys in the hash table. This function may be used to
3475 find all of the keys from the hash.
3477 Added user_context arguments to the SilcHashFunction,
3478 SilcHashCompare and SilcHashDestructor to deliver user specified
3481 Added new fuctions silc_hash_table_find[_all]_ext to do
3482 extended lookup with specified hash and compare functions and
3483 specified user contexts.
3485 Added new function silc_hash_table_add_ext to add the key
3486 with specified hash function and user context.
3488 Added new function silc_hash_table_foreach to traverse all
3489 entrys in the hash table. Added SilcHashForeach callback
3492 Added new function silc_hash_table_del_by_context to delete
3493 the entry only if the context associated with the key matches.
3495 Affected files are lib/silcutil/silchashtable.[ch].
3497 * Removed silc_hash_[server/client/channel]_id and added just
3498 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3499 silc_hash_id_compare to compare two ID's using as the hash table
3500 comparison function. Added also silc_hash_data to hash
3501 binary data and silc_hash_data_compare to compare it.
3503 * Removed silc_idlist_find_client_by_hash as it is not needed
3504 anymore. Affected file silcd/idlist.[ch].
3506 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3507 to use internally the SilcHashTable. The new ID Cache is a lot
3508 faster than the old one. Some of the ID Cache interface was also
3509 rewritten and obsolete and stupid functions were removed.
3511 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3513 * Added entry_count field to the SilcHashTable to keep the number
3514 of the entries in the table. Implemented the function
3515 silc_hash_table_rehash. Added new function
3516 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3518 Fixed a minor bug in silc_hash_table_free.
3520 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3521 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3522 into the lib/silcutil/silcutil.[ch].
3524 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3526 * Implemented a collision resistant hash table into the
3527 lib/silcutil/silchashtable[ch]. See the header and the source
3528 for the SilcHashTable API.
3530 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3532 * Merged dotconf version 1.0.2 into lib/dotconf.
3534 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3536 * Do not compile anything in lib/silcsim/* if the SIM support
3537 is not enabled. The tree should now compile without problems
3540 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Compiled the SILC under cygwin. Compiled and tested briefly
3543 without problems. More tests needed. The SIMs didn't compile
3546 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3548 * Fixed possible crash in silc_get_username in the
3549 lib/silcutil/silcutil.c.
3551 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3553 * Fixed a va_arg in silc/client_ops.c.
3555 * Oops, RC5 routines were named AES and caused some problems
3556 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3558 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3560 * Added new SilcIDIP structure into the lib/silccore/id.h and
3561 replaced the old `ip' fields from all SILC ID's to that type.
3562 This is a step towards IPv6 support.
3564 The silc_id_get_len takes now the ID as an extra argument.
3565 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3566 both IPv4 and IPv6 based ID's.
3568 The affected files are lib/silccore/id.[ch] and other files
3569 around the tree using these routines.
3571 * Removed the ID length arguments in server from various
3572 silc_server_send_notify_* routines -> they are not needed
3575 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3577 * Fixed memory leak in silc_encode_pem_file in the file
3578 lib/silcutil/silcutil.c.
3580 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3582 * Check minor version as well in the SKE. Affected files are
3583 silcd/protocol.c and lib/silcclient/protocol.c.
3585 * Added --identifier option to the server so that an identifier
3586 can be when creating the public key for the server. Affected
3587 file is silcd/silcd.c.
3589 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3590 lib/silccrypt/silcpkcs.c.
3592 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3594 * Register default ciphers and stuff when using -C option with
3595 the server. Affected file sildc/silcd.c.
3597 * Put back the servers public key filename format, it is better
3598 than the new one. For now, the client keys are saved with the
3599 new filename format. The affected file silc/client_ops.c.
3601 * Implemented the Cipher API for the rest of the ciphers that
3602 did not implement it or implemented it the wrong way.
3604 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3606 * Register default ciphers and stuff when using the -S option
3607 in the client. Affected file silc/silc.c. Same also when
3608 creating new key pair with -C option.
3610 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3612 * Fixed the silc_verify_public_key client operation function to
3613 save the public keys differently. The fingerprint is now
3614 used as filename and not the hostname. This way also the
3615 client keys are saved uniquely and not with hostnames. The
3616 affected file is silc/client_ops.c.
3618 * Trimmed the silc_hash_fingerprint function to remove extra
3619 whitespaces from the end of the fingerprint. The affected
3620 file is lib/silccrypt/silchash.c.
3624 * Added silc_cipher_register_default function to register all
3625 default ciphers. It can be used when configuration files
3626 does not exist and the application does not want any specific
3627 ciphers in any specific order.
3629 The SilcDList is now used as silc_cipher_list dynamically
3630 allocated cipher list. Removed the static list all together
3631 and now all ciphers must be allocated to the dynamic list.
3632 The silc_cipher_alloc routine was changed to check only the
3635 All silc_cipher_* routines that used to return int returns
3638 The affected files lib/silccrypt/silccrypt.[ch].
3640 * The same thing was done to silc_hash_* as for silc_cipher_*
3641 routines. Affected files lib/silccrypt/silchash.[ch].
3643 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3644 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3645 Added also silc_pkcs_[un]register[_default] functions.
3646 Removed the data_context from the PKCS API.
3648 * Added silc_hmac_register_default function to register default
3649 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3650 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3651 to unregister all hmacs at once.
3653 * Register the default ciphers, hash functions, PKCSs and HMACs
3654 if client's configuration file does not exist. The affected
3657 * The client did not load the hash functions from the SIM
3658 modules at all. Added support for this. Affected file is
3659 silc/clientconfig.c.
3661 * When decoding public key with silc_pkcs_public_key_decode, check
3662 the supported algorithm only if PKCS are registered. Affected
3663 file lib/silccrypt/silcpkcs.c. The same was done with the
3664 silc_pkcs_private_key_decode.
3666 * Fixed the SILC List routines to keep the list always in order.
3667 It used to change the list's order when traversing the list but
3668 not it preserves the order. Affected file lib/trq/silclist.h.
3670 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * Added the client library to use the SilcSocketConnection's
3673 reference counter (by silc_socket_dup) to prevent the bug that
3674 the socket object may be freed underneath async operation.
3676 * The name resolv library checking fixes in the configure.in.pre.
3679 * Created new version of the protocol drafts for future
3680 development. The -03 drafts are the ones that will be changed
3681 in the trunk now and the -02 will remain as they are.
3683 * Send list of CUMODE notifys to the router when announcing
3684 the channel users to the router. Affected file silcd/server.c.
3685 If the router receiving channel founder CUMODE for a channel
3686 that already has channel founder it will send CUMODE notify
3687 to the sender to remove the channel founder rights from the
3688 announced client. Affected file silcd/packet_receive.c.
3690 * The CUMODE notify may now use Server ID as well as the entity
3691 who changes the mode. Updated protocool specs.
3693 * Updated INSTALL and README files.
3695 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * New web pages in the http://silc.pspt.fi. The pages was
3702 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3704 * Implemented the [DenyConnectin] config section in the server.
3705 Added silc_server_config_denied_conn to check whether incoming
3706 connection is denied. Affected file silcd/serverconfig.[ch].
3708 * Do not check the ports when checking the incoming configuration
3709 data if the port is 0, meaning any. Affected file is
3710 silcd/serverconfig.c.
3712 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3714 * Fixed buffer overflow in silc_string_compare in the file
3715 lib/silcutil/silcutil.c.
3717 * Fixed double free in silc_server_command_leave in the file
3720 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * Fixed the version checking in the server. Affected file is
3725 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * Fixed the configuration data fetching when accepting new
3728 connections in the server. Affected file silcd/server.c.
3730 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3732 * Added `sender_entry' argument to the function
3733 silc_server_packet_relay_to_channel so that we can check
3734 whether some destination actually belongs to the same route
3735 the sender belongs (ie, we must not resend the packet to the
3736 sender). Affected file silcd/packet_send.[ch].
3738 * Added `servername' field to the SilcClientEntry in the server
3739 to hold the name of the server where client is from. Affected
3740 file is silcd/idlist.h.
3742 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * Moved the channel message encrypting in the router betwen
3745 router connections from silc_server_channel_message to the
3746 silc_server_packet_relay_to_channel since we want to check
3747 whether we have anybody channel before encrypting anything.
3748 Affected files silcd/packet_[receive/send].c.
3750 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3752 * Fixed the [AdminConnection] server config section to support
3753 multiple entries. Affected file silcd/serverconfig.c.
3755 * Added support into the server to check the validity of the
3756 incoming connection before executing any KE or authentication
3759 * The connection configuration is now saved to the KE and
3760 connection auth protocol contexts and not fetched anymore in
3761 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3763 * The local hosts listenning address and port is also resolved
3764 now when starting the server. We want to have the socket object
3765 to include the real address and port for the listener. Added
3766 new function silc_net_check_local_by_sock into the files
3767 lib/silcutil/silcnet.[ch].
3769 * Fixed a broadcast bug in server -> do not broadcast if we
3772 * Fixed a routing bug. Do not route broadcast packets ever.
3773 Broadcast packets must be processed always and not routed since
3774 they may be destined to some other host than yourself and thus
3775 would get routed without no good reason. Affected file is
3778 * Added function silc_server_config_is_primary_route to check
3779 whether primary router connection has been configured (a router
3780 configuration that we are initiating). If there is not, we
3781 will assume that there is only two routers in the SILC network
3782 and we will use the incoming router connection as our primary
3783 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3785 * Changed the order of the broadcasting. Broadcast _after_ the
3786 packet has been processed not before. Affected file is
3789 * Fixed a [ClientConnection] parsing bug. The port was never
3790 parsed correctly thus resulting to port 0. Affected file
3791 silcd/serverconfig.c.
3793 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3794 argument and did not set the broadcast packet flag. Affected
3795 file silcd/packet_send.c. Fixed same bug in the function
3796 silc_server_send_notify as well.
3798 * If we receive NEW_ID packet for our own ID in the server, ignore
3801 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Removed the nickname from the Private Message Payload.
3806 Updated the code and the protocol specs.
3808 * Updated protocol specs for submitting to the IETF.
3810 * Tweaked the Random Number Generator a bit. Affected file
3811 lib/silccrypt/silcrng.c. Exported a new function
3812 silc_rng_[global]_add_noise which can be used to add more
3815 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3817 * Do not parse packets with different timeout when protocol
3818 is active -> may cause problem with rekey. Affected file
3821 * When server receives signoff notify it must not create
3822 new channel key if the client is on any channels since the
3823 sender of the signoff notify will create it.
3825 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3827 * Added printing of error messages during SKE protocol from the
3828 failure packet sent by server during SKE. Affected file
3831 * Removed the client's failure_callback handling with timeout
3832 and handle it immediately when received.
3834 * The SKE library returned wrong type in SUCCESS and FAILURE
3835 packets. They must be 32 bit MSB not 16 bit MSB.
3837 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3839 * Ok, rewrote the logic of the re-key and now it seems to work.
3840 I tested it on high traffic with frequent re-keys without
3841 problems. Added hmac_receive (and renamed hmac to hmac_send)
3842 in SilcClientConnection in lib/silcclient/client.h and
3843 in SilcIDListData in silcd/idlist.h. Also, removed the
3844 SilcPacketParserContext's cipher and hmac fields as they are
3845 not needed anymore and actually caused some problems when
3846 the ciphers and hmac's changed underneath the packet parser.
3848 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3850 * If re-key protocol is active then process the incoming packets
3851 synchronously since we must assure that icoming packets encrypted
3852 with the old key is processed before the new keys is set to
3853 use. This is true other packets than for REKEY packets.
3854 Affected file silcd/server.c. The same was done to client library
3855 as well, affected file lib/silcclient/client.c.
3857 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3859 * Fixed bug in client and server to accept the force send if
3860 the packet is send from silc_[server/client]_packet_process
3861 function. Otherwise the packets are never delivered, oops.
3863 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3865 * Disable force sending of packets when REKEY protocol is active.
3866 We must assure that no packet is sent directly when rekey is
3867 performed. All packets must be sent through packet queue.
3868 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3869 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3870 function is silc_[server/client]_packet_send_real to check
3873 * Replaced the SIM paths from example config files to
3874 /usr/local/modules. Also, make install creates now
3875 /usr/local/silc/logs directory to hold all the SILC server
3878 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3880 * Made the configure.in.pre work on Solaris. Patch by salo.
3882 * Made all ciphers compatible with non-x86 machines. Defined
3883 CBC mode macros into lib/silccrypt/ciphers_def.h.
3885 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3887 * Fixed the make install.
3889 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3891 * When MAC computation fails the silc_packet_decrypt returned 0
3892 even though it was supposed to return -1. Fixed this. The
3893 affected file is lib/silccore/silcpacket.c.
3895 * Do not replace the config files in /etc/silc (in make install)
3896 if they already exist. Affected file ./Makefile.am.
3898 * Do not send re-key packets immediately but through packet queue.
3899 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3901 * Changed silc_net_check_host_by_sock to return FALSE if the
3902 IP/DNS could not be resolved. Though, it returns the IP address
3903 now even if it could not resolve it (but returns also FALSE).
3904 Affected file lib/silcutil/silcnet.[ch].
3906 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3908 * Added silc_pkcs_decode_identifier to decode the public key's
3909 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3910 Added also silc_pkcs_free_identifier. Added also new context
3911 SilcPublicKeyIdentifier.
3913 * Added -S option to the silc client. It is used to dump the
3914 contents of the specified public key file.
3916 * Changed the PKCS api to return the public key length when
3917 setting the public key.
3919 * Fixed a fatal bug in the public and private key file loading.
3920 Affected file lib/silccrypt/silcpkcs.c.
3922 * Execute the packet parsing for client with zero (0) timeout
3923 if the protocol is active. Affected file silcd/server.c.
3925 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3927 * Made the key generation options to the silcd program. Added
3928 -C option, equivalent to client's option.
3930 * Added new [ServerKeys] config section to the server. It
3931 configures the server's public and private key.
3933 * Defined generic Public Key Payload into the protocol
3934 specification to send specific type of public keys and
3937 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3938 public key or certificate.
3940 * Implemented the GETKEY command to the server and to the
3941 client library and on user interface.
3943 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3945 * Made preliminary `make install' work.
3947 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3949 * Added SilcServerRekey context into silcd/idlist.h.
3951 * Added the PFS support as defined in the specification to the
3952 SKE protocol. Affected files lib/silcske/*.c.
3954 * Added `ske_group' field to the SilcServerRekey context to hold
3955 the number of the SKE group that is used with PFS in re-key.
3956 Affected file silcd/idlist.h.
3958 * Added PFS re-key support to the server. Affected file is
3961 * Added silc_protocol_cancel to cancel execution of the next
3962 state of the protocol. Affected file is
3963 lib/silccore/silcprotocol.[ch].
3965 * Added the re-key support with and without PFS to the client
3966 library. Re-key is performed once in an hour, by default.
3968 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3969 Added silc_client_rekey_callback and silc_client_rekey_final.
3970 Affected files are lib/silcclient/protocol.[ch] and
3971 lib/silcclient/client.[ch].
3973 * Removed the `hmac_key' and `hmac_key_len' fields from the
3974 SilcClientConnection structure; not needed. Affected file is
3975 lib/silcclient/client.h.
3979 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3981 * Do not ask whether user wants to use the negotiated private key
3982 for private messages, just use it. Affected file is
3983 silc/local_command.c.
3985 * Added `send_enc_key' and `enc_key_len' fields to the
3986 SilcIDListData structure since they are needed in the re-key
3987 phase. Affected file is silcd/idlist.[ch].
3989 * Implemented the simple re-key protocol into the server.
3990 Affected files silcd/server.c and silcd/protocol.[ch]. The
3991 re-key will be performed once in an hour, by default.
3993 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3994 Added silc_server_rekey, silc_server_rekey_callback and
3995 silc_server_rekey_final.
3997 * Removed Tunneled flag from the protocol. Updated the code
3998 and the specifications.
4000 * Adde `pfs' field to the SilcIDListData to indicate whether
4001 the PFS is to be performed in the re-key. Affected file is
4004 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4006 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4007 int64 of at least the xintXX size. If void * is less that 4
4008 bytes uint32 * will be used. Defined bool as boolean.
4010 * Changed _ALL_ unsigned long and unsigned int to uint32,
4011 unsgined short to uint16 in the source tree.
4013 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4014 not handle clients that has entry->data.registered == FALSE.
4015 They are not in the network anymore. Affected file is
4018 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4020 * Implemented the sending of the SERVER_SIGNOFF notify in the
4021 server. Affected file is silcd/server.c.
4023 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4024 Added also silc_notify_payload_encode_args into the
4025 lib/silccore/silcnotify.[ch].
4027 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4028 Affected file silcd/packet_receive.c.
4030 * Implemented the SERVER_SIGNOFF notify handling in the client
4031 library. Affected file lib/silcclient/client_notify.c. Also,
4032 implemnted the printing of the SERVER_SIGNOFF info to the
4033 application. Affected file silc/client_ops.c.
4035 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4036 if the deleting was successful. Affected file silcd/idlist.[ch].
4038 * Added support for public key authentication in the connection
4039 authentication protocol in the client library. Affected file
4040 lib/silcclient/protocol.c.
4042 * Changed the server's silc_idlist_get_clients_by_* interface
4043 to support already allocated array so that new entries may be
4044 added to pre-allocated array. Affected file silcd/idlist.[ch].
4045 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4046 and command replies.
4048 * All command reply functions in the server now calls the
4049 pending command callback even if error occured. This way the
4050 error will be delivered to the client as well. Affected files
4051 silcd/command.c and silcd/command_reply.c.
4053 * Fixed INFO command to return local server's info if no server
4054 was provided. Affected file lib/silcclient/command.c.
4056 * Removed RESTART command for good. Updated the code and the
4059 * Rewrote parts of the task system. It is a bit simpler now.
4060 Removed unsued task priorities. The affected files are
4061 lib/silcutil/silctask.[ch].
4063 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4065 * Moved the USERS printing from the library to the application.
4066 Affected files lib/silcclient/command.c and silc/client_ops.c.
4068 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4072 * Added channel key re-key support. The re-key is perfomed
4073 only by the router and is done once in an hour. Added `rekey'
4074 field to the SilcChannelEntry in the server. Affected files
4075 silcd/server.c and silcd/idlist.h.
4077 * Added silc_task_unregister_by_context into the file
4078 lib/silcutil/silctask.[ch].
4080 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4082 * Added SILC_UMODE_GONE mode to indicate when the client is not
4083 present in the SILC network. Added also support to the local
4084 command AWAY that will set this mode. Added support of showing
4085 "xxx is gone" in WHOIS command. The USERS command shows the
4086 gone status as well.
4088 * Fixed setting server and router operator privileges in the
4089 server's UMODE command. Affected file silcd/command.c.
4091 * Merged the SKE KE1 and KE2 payloads into one payload. The
4092 new KE payload is equivalent to the old KE2 payload.
4094 Cleaned up the SKE Start Payload parsing. It now uses the
4095 simple buffer unformatting to do the parsing. A lot faster
4098 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4099 to the SKE that is used to indicate whether both of the SKE
4100 parties should perform authentication. By default only the
4101 responder performs authentication. By setting this flag also
4102 the initiator must do authentication. By default it is unset
4103 since in normal SKE case, client to server connection, only
4104 the responder should do authentication. When doing SKE between
4105 two clients both should perform authentication. Updated the
4106 code and the protocol specs.
4108 * A little fix to IDENTIFY command in the server. Search the
4109 client first by hash not nickname. Affected file is
4112 * Fixed the silc_client_close_connection to support closing
4113 the client to client connections wihtout deleting too much
4114 data. Affected file lib/silcclient/client.c.
4116 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4117 are received if protocol used to be active but is not anymore
4118 the application would crash due to NULL pointer dereference.
4119 Affected files silcd/server.c and lib/silcclient/client.c.
4121 * Added `hash' field to the SilcClientConnection to include
4122 the hash function negotiated in the SKE protocol.
4124 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4125 to set the channel founder authentication data. A client can
4126 claim the founder rights later by providing the authentication
4127 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4128 This way the channel founder can regain the channel founder
4129 privileges even it is left the channel. This works only on
4130 local server and the client must be connected to the same
4131 server to be able to regain the founder rights. Updated the
4132 protocol specs accordingly.
4134 Added support to the CMODE command in the client to set the
4135 founder auth data. Read the README to see how to set it.
4137 Added support to the CUMODE command to claim the founder
4138 rights. Read the README to see how to do it.
4140 Added support for the founder authentication to the Channel
4141 Entry in the server. Affected file silcd/idlist.h.
4143 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4144 server's CMODE command. Affected file silcd/command.c.
4146 * Added the following new functions into lib/silccore/silcauth.[ch]:
4147 silc_auth_get_method and silc_auth_get_data.
4149 * The server now saves the remote hosts public key to the
4150 SilcIDListData pointer. Affected file silcd/protocol.c.
4152 * The normal server now does not remove the channel entry from
4153 the cache if the founder authentication data is set. It used
4154 to remove it if the founder was the last one on the channel on
4155 the server and left the channel. The auth data is saved and
4156 if the channel is re-joined later the old entry is used with
4157 the old auth data. Affected files silcd/command_reply.c and
4160 * Removed the `pkcs' field from the SilcIDListData structure
4161 in the server; it is not used. Affected file silcd/idlist.h.
4163 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4165 * Fixed packet processing on slow links. Partial packets were
4166 never re-processed because the incoming data buffer was cleared
4167 by the application. Application must not directly clear the
4168 sock->inbuf, the packet processing routines handle it. Fixed
4169 this in client library and in server.
4171 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4173 * Fixed the WHOIS and IDENTIFY send reply function to really
4174 check whether to send list or just one entry. Affected file
4177 * Cleaned up the LEAVE command's channel key distribution. The
4178 affected file silcd/command.c.
4180 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4181 can enforce the channel mode as well. In that case the ID
4182 includes the ID of the server. The code now enforces the
4183 mode change if the router have different mode than the server.
4185 * The notify client operation with CMODE_CHANGE notify can now
4186 return NULL client_entry pointer if the CMODE was not changed
4187 by client. Application must check for this.
4189 * Added <Server ID> argument to INFO command to support server
4190 info fetching by Server ID.
4192 * Added silc_server_announce_get_channel_users to get assembled
4193 packets of channel users of the specified channel. Affected
4194 file silcd/server.[ch].
4196 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4197 was freed underneath the ID Cache.
4199 * Re-announce clients when the server received CHANNEL_CHANGE
4200 notify from the router. Affected file silcd/packet_send.c.
4202 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4204 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4205 crashed since it did not handle the fact that there is no cipher
4206 called "3" and didn't check the error condition. Now fixed.
4208 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4209 flag. It can be used to send message requests.
4211 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4213 * Implemented the RESTART command in the client.
4215 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4216 notice type messages. Added notice printing to the user
4219 * The channel keys are not re-generated if the channel's mode
4220 is PRIVKEY, ie private key on the channel exists. Affected
4221 files silcd/server.c and silcd/command.c.
4223 * Fixed a little bug in channel message delivery when channel
4224 private keys are set in the server. Affected file is
4225 silcd/packet_send.c.
4227 * Changed the setting on channel->on_channel = TRUE from the
4228 silc_client_save_channel_key to the JOIN command reply. The
4229 key payload is not received if the private channel key is set.
4230 Affected file lib/silcclient/command_reply.c and the
4231 lib/silcclient/client_channel.c.
4233 * When the CMODE_CHANGE notify is sent and the channel private
4234 key mode is removed the channel key must be re-generated in
4235 other cells as well. Added this support for the router in the
4236 silcd/packet_receive.c.
4238 * Added new local command NOTICE to send notice message on
4239 channel. Affected file silc/local_command.[ch].
4241 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4243 * Added new local command ME to the client. It is used to send
4244 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4245 some action. Affected file silc/local_command.[ch].
4247 * Changed channel_message and private_message client operations
4248 to deliver the message flags to the application. Added also
4249 the `flags' arguments to the silc_client_send_channel_message
4250 and silc_client_send_private_message functions. Affected file
4253 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4255 * Redefined the Private Message Payload to support private message
4256 keys and to support the new private message flags. Updated
4257 the protocol specs. Flags makes it possible to have for example
4258 CTCP style messages.
4260 * Added new type SilcPrivateMessagePayload and defined an API
4261 for it in the lib/silcclient/silcprivate.[ch].
4263 * Tested private message private keys successfully. Tested the
4264 private message key set, unset and list commands with the new
4267 * Redefined the Channel Message Payload to include the channel
4268 message flags (equal with private message flags) to support
4269 for example CTCP style messages.
4271 * Defined some of the message (for channel and private message)
4272 flags. Updated the protocol specs and added the flags to the
4273 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4275 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4277 * Added SilcKeyAgreementStatus type to the key agreement routines
4278 to indicate the current status and error if one occured.
4279 The status types are defined in the lib/silcclient/silcapi.h.
4281 * Added new local command KEY that is used to set and unset private
4282 keys for channels, set and unset private keys for private messages
4283 with remote clients and to send key agreement requests and
4284 negotiate the key agreement protocol with remote client. The
4285 key agreement is supported only to negotiate private message keys,
4286 it currently cannot be used to negotiate private keys for channels,
4287 as it is not convenient for that purpose.
4289 * Fixed a minor pending callback setting bug in the function
4290 silc_client_get_client_by_id_resolve, now the function works.
4291 Affected file lib/silcclient/idlist.c.
4293 * Added function silc_net_get_local_port to get local bound
4294 port by socket. Added to lib/silcutil/silcnet.[ch].
4296 * Added `sockets' and `sockets_count' fields to the SilcClient
4297 object. They hold the sockets of the listenning sockets in
4298 the client. Listenning sockets may be for example the key
4299 agreement server. Affected file lib/silcclient/client.[ch].
4300 Added functions the silc_client_add_socket and the
4301 silc_client_del_socket. They are exported to the application
4304 * Added ~./silc/clientkeys to support other client's public keys.
4306 * Renamed verify_server_key client operation to verify_public_key
4307 and added one argument to indicate the type of the connection
4308 (server, client etc.).
4310 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4312 * Added silc_server_connection_auth_request to handle the
4313 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4314 silcd/packet_receive.[ch].
4316 * Added silc_server_send_connection_auth_request into the
4317 silcd/packet_send.c to send the connection auth request packet.
4319 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4322 * Fixed the public key authentication in responder side in the
4323 server. The `auth_data' pointer includes the SilcPublicKey
4324 not the path to the public key. Affected file silcd/protocol.c.
4326 * Implemented the public key authentication in the initiator side
4327 in the server. Affected file silcd/protocol.c.
4329 * Removed the [RedirectClient] config section from the server
4330 configuration. Is not needed and I don't want to implement it.
4332 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4334 * Cleaned up the CMODE command in the server. It now works
4335 correctly and supports all the modes defined in the protocol.
4336 Affected file is silcd/command.c.
4338 * Added `hmac_name' field to the SilcChannelEntry in the server
4339 to hold the default HMAC of the channel. It can be set when
4340 creating the channel (with JOIN command). Affected files
4343 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4344 type to indicate the change of the current cipher and hmac
4345 on the channel. Client can safely ignore the <cipher> argument
4346 (if it chooses to do so) since the CHANNEL_KEY packet will
4347 force the channel key change anyway. The <hmac> argument is
4348 important since the client is responsible of setting the new
4349 HMAC and the hmac key into use.
4351 * Fixed the CMODE command in the client library as well.
4353 * Tested CMODE command in router environment successfully.
4355 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4357 * Show the version of the remote client (or server) when connecting
4358 to the server. It is logged to the log file. Affected file
4359 is silcd/protocol.c.
4361 * Fixed the KILLED notify handling in the client library. The
4362 client must be removed from all channels when receiving the
4365 Also, do not remove the client entry when giving the KILL
4366 command but when the KILLED notify is received.
4368 * Removed silc_idlist_find_client_by_nickname from the server.
4369 Not needed anymore. Affected files silcd/idlist.[ch].
4371 * Implemented the CHANNEL_CHANGE notify type handling to the
4372 server. Affected file silcd/server.c.
4376 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4378 * Added silc_server_send_notify_invite to send the INVITE
4379 notify between routers.
4381 * Implemented the INVITE command correctly to the server.
4383 * Implemented the INVITE notify type handling in the server.
4385 * Implemented the INVITE command to the client library and on the
4388 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4390 * Added function silc_server_get_client_resolve to find the
4391 client entry by ID from all ID lists and then resolve it
4392 (using WHOIS) if it cannot be found. Affected file is
4395 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4397 * Implemented the BAN command to the client library.
4399 * The JOIN command in the server now checks the invite list
4402 * Changed the silc_command_reply_payload_encode_va and the
4403 silc_command_payload_encode_va to support that if argument is
4404 NULL it ignores and checks the next argument. Affected file
4405 lib/silccore/silccommand.c.
4407 * Added silc_server_send_notify_ban to send the BAN notify
4408 type between routers.
4410 * Chaned the silc_notify_payload_encode to support that if
4411 argument is NULL it ignores and checks the next argument.
4412 Affected file lib/silccore/silcnotify.c.
4414 * Tested ban lists in router environment successfully.
4416 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4418 * Implemented BAN command to the server, in silcd/command.[ch].
4420 * Removed the BAN and INVITE_LIST modes from the CMODE command
4423 * Added function silc_string_match to regex match two strings.
4424 Affected files lib/silcutil/silcutil.[ch].
4426 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4428 * Redefined parts of the SilcChannelEntry in the server to support
4429 the new ban and invite lists.
4431 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Redefined the INVITE command. The same command can be used to
4434 invite individuals to the channel but also to manage the invite
4435 list of the channel (to add to and remove from the invite list).
4436 Updated the protocol specs.
4438 * Added new command SILC_COMMAND_BAN that can be used to manage
4439 the ban list of the channel. Updated the protocol specs.
4441 * Removed the channel modes: the SILC_CMODE_BAN and the
4442 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4443 in the CMODE command. The equivalent features are now available
4444 using INVITE and BAN commands. Updated the protocol specs.
4446 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4447 in the network about change in the current ban list. The notify
4448 type is not used by the client.
4450 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4451 support the invite lists.
4453 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * Added new function silc_string_regexify that converts string
4456 including wildcard characters into regex string that can
4457 be used by the GNU regex library. Added into the file
4458 lib/silcutil/silcutil.[ch].
4460 Added silc_string_regex_combine to combine to regex strings
4461 into one so that they can be used as one regex string by
4462 the GNU regex library. Added into the file
4463 lib/silcutil/silcutil.[ch].
4465 Added silc_string_regex_match to match two strings. It returns
4466 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4468 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4470 * Imported GNU regex to the soruce tree into lib/contrib.
4471 Fixed some compiler warning from the regex.c.
4473 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4475 * Fixed MOTD command in the server to work in router environment.
4477 * Fixed the MOTD command in the client library to support
4478 the server argument in the command.
4480 * Added `nickname_len' argument to the silc_idlist_add_client
4481 in the server, as the `nickname' argument may be binary data
4484 * Added silc_idlist_get_channels to return all channels from
4487 * Implemented LIST command to the server. Affected file is
4490 * Implemented the LIST command to the client library and on the
4493 * Added [<user count>] argument to the LIST command reply.
4494 With private channels the user count is not shown.
4496 * Updated TODO and README.
4498 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4500 * The client entry's data.registered must be TRUE even with
4501 global client entry on global client list. The data.registered
4502 is used to check whether the client is anymore in the network,
4503 for example with WHOWAS command so it must be valid.
4505 * Fixed the WHOWAS command in the server. It now actually works
4506 in router environment. Added function into silcd/command_reply.c
4507 silc_server_command_reply_whowas_save.
4509 * Added silc_idlist_purge function to the silcd/idlist.c
4510 to periodically purge the ID Cache.
4512 * Fixed INFO command in the server. It works now in router
4513 environment. Added <server name> argument to the INFO command
4514 reply. Updated the protocol specs.
4516 * Fixed minor bug in silc_idcache_purge to not purge if the
4517 expire value is zero.
4519 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4520 they were buggy because of the WHOWAS information.
4522 * Fixed local command MSG to handle the async resolving of
4523 the remote client properly. It used to fail the first MSG.
4524 Affected file silc/local_command.c.
4526 * Added `data_len' field to SilcIDCache context.
4528 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4530 * Update TODO. Todo in commands in the server.
4532 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4535 used by routers as broadcast packet to inform other routers
4536 about the changed user mode.
4538 Implemented the notify handling in the server. Affected file is
4539 silcd/packet_receive.c. Added the function
4540 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4542 * Added new generic Channel Payload and deprecated the New Channel
4543 Payload. The New Channel Payload is now the generic Channel
4546 * Added new argument `mode' to the silc_server_send_new_channel
4547 as it is required in the Channel Payload now.
4549 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4550 and created a new and real SilChannelPayload to represent the
4551 new generic Channel Payload. Implemented the encode/decode
4552 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4554 * Added silc_server_get_client_channel_list to return the list
4555 of channels the client has joined for WHOIS command reply.
4556 Affected file silcd/server.[ch].
4558 * Implemented the channel list sending in the WHOIS command reply
4559 in server and in the client.
4561 Implemented the channel list displaying on the user interface
4562 as well. Affected file silc/client_ops.c.
4564 * Added silc_channel_payload_parse_list to parse list of Channel
4565 Payloads. It returns SilcDList list of SilcChannelPayloads.
4566 Client for example can use this function to parse the list of
4567 channels it receives in the WHOIS command reply. The caller
4568 must free the list by calling silc_channel_payload_list_free.
4569 Affected files lib/silccore/silcchannel.[ch].
4571 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4573 * Added one new argument <user mode> to the WHOIS command reply
4574 to return the mode of the user in SILC. Updated the protocol
4577 Implemented it to the server and client.
4579 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4581 * Fixed the mode printing on the user interface on joining.
4582 Affected file silc/client_ops.c.
4584 * Implemented the UMODE command and user modes in general to the
4585 client library and to the user interface.
4587 * Implemented the UMODE command to the server.
4589 * The server now sends UNKNOWN_COMMAND error status if client sends
4590 unknown command. Affected file silcd/command.c.
4592 * All server commands now handle the command identifier the right
4593 way when sending the command reply to the client. The client can
4594 use to identify the command replies with the identifier.
4596 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4598 * Added silc_server_get_client_route to resolve the route to
4599 the client indicated by the client ID. Affected file is
4602 * Added silc_server_relay_packet as general function to relay
4603 packet to arbitrary destination. This deprecates functions
4604 like _send_private_message_key, _relay_notify etc. Affected
4605 file is silcd/packet_send.[ch].
4607 Removed silc_server_send_key_agreement,
4608 silc_server_send_private_message_key and
4609 silc_server_packet_relay_notify functions from the file
4610 silcd/packet_send.[ch].
4614 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4615 server. Affected file silcd/packet_receive.[ch].
4617 * Implemented the KILL command to the client. Implemented the
4618 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4619 Affected files lib/silcclient/command[_reply].c and
4620 lib/silcclient/client_notify.c. Implemented the KILL notify
4621 printing in the user inteface.
4623 * Fixed a lot silc_parse_nick memory leaks from the client
4624 library in the file lib/silcclient/command.c.
4626 * Changed the silc_server_send_notify_on_channels's `sender'
4627 argument from SilcSocketConnection to SilcClientEntry to
4628 check the sender as entry and not as connection object and not
4629 to send to the client provided as argument. The affected file
4630 is silcd/packet_send.[ch].
4632 * The notify packets that are destined directly to the client used
4633 to not to be processed by the server. Now changed that and the
4634 server processes all notify packets. After relaying the packet
4635 to the client the notify packet is processed in the server.
4637 * The silc_server_free_client_data now checks whether there is
4638 pending outgoing traffic for the client and purges the data to
4639 the network before removing the client entry.
4641 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4643 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4644 an client is killed from the SILC Network. Updated the protocol
4647 Added new function silc_server_send_notify_killed to the
4648 silcd/packet_send.[ch].
4650 * Added function silc_server_packet_relay_notify to relay notify
4651 packets that are destined directly to a client. In this case
4652 the server does not process the notify packets but merely relays
4653 it to the client. Affected file silcd/packet_send.[ch].
4655 Added also silc_server_packet_process_relay_notify to check
4656 whereto relay the notify. Affected file is
4657 silcd/packet_receive.[ch].
4659 * Implemented the KILL command to the server.
4663 * Added the backup schema desgined last fall to the protocol
4664 specs for everyone to see. The specification is in the
4665 *-spec-xx.txt draft and the packet type definitions for the
4666 backup routers is in *-pp-xx.txt draft. Thusly, added also
4667 new packet type SILC_PACKET_CELL_ROUTERS.
4669 * A big security problem in the implementation discovered. The
4670 signoff of an client did not cause new channel key generation
4671 which it of course should've done. The channel keys must be
4672 always re-generated when client leaves (or signoffs) the channel.
4673 The silc_server_remove_from_channels funtion now handles
4674 the channel key re-generation.
4676 * Added `sender' argument to the silc_server_send_notify_on_channels
4677 to not to send the client provided as argument. Affected file
4678 silcd/packet_send.[ch].
4680 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4682 * Implemented OPER and SILCOPER commands into the server and
4685 * Added silc_auth_verify and silc_auth_verify_data to verify
4686 the authentication directly from the authentication payload.
4687 It supports verifying both passphrase and public key based
4688 authentication. Affected file lib/silccore/silcauth.[ch].
4690 * Added `hash' field to the SilcIDListData structure. It is the
4691 hash negotiated in the SKE protocol. Affected file is
4694 * Slight redesigning of the SilcAuthPayload handling routines.
4695 Do not send SilcPKCS but SilcPublicKey as argument.
4697 * Implemented the public key authentication support to the
4698 serverconfig. The public key is loaded from the provided path
4699 and saved as authentication data to void * pointer. Thus,
4700 changed the unsigned char *auth_data to void *auth_data;
4702 * Fixed SHUTDOWN command to send the reply before the server
4703 is shutdown. :) Affected file silcd/command.c.
4705 * Fixed fatal bug in CONNECT command. The hostname was invalid
4706 memory and server crashed. Affected file silcd/command.c.
4708 * Fixed fatal bug in CLOSE command. The server_entry became
4709 invalid but was referenced later in the command. Affected file
4712 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Fixed fatal bug in failure packet handling. Server ignored
4715 the failure and thus crashed when it came.
4719 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4721 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4722 that the command may be executed only once in (about) 2 seconds.
4723 The old SILC_CF_LAG flag is same but allows command bursts up
4724 to five before limiting.
4726 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4727 server code. Various commands now includes the CF_LAG_STRICT
4728 flag to disallow any kind of miss-use of the command.
4730 * Fixed the silc_buffer_unformat to not to allocate any data
4731 if the length of the data is zero. It used to allocate the
4732 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4734 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4736 * Changed the format of AdminConnection configuration section
4737 in the server. Added username of the admin to the format.
4738 Affected files silcd/serverconfig.[ch].
4740 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4741 to return admin configuration data by host, username and/or
4744 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4746 * Implemented WHOWAS command to the server. Added the functions:
4748 silc_server_command_whowas_parse,
4749 silc_server_command_whowas_send_reply,
4750 silc_server_command_whowas_from_client and
4751 silc_server_command_whowas_from_server
4753 * Added <Client ID> argument to the WHOWAS command reply. Updated
4754 the protocol specs accordingly.
4756 * Implemented WHOWAS command and command_reply to the client
4759 Implemented the WHOWAS printing on the user interface.
4761 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * Added new argument to the WHOWAS command reply, the real name.
4764 It is an optional argument. Updated the protocol specs.
4766 * Added SilcIDCacheDestructor callback that is registered when
4767 the SilcIDCache is allocated. The callback is called when
4768 an cache entry in the ID Cache expires, or is purged from the
4769 cache. Added into lib/silccore/idcache.[ch].
4771 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4772 to destruct the client entries when the cache entry expires.
4773 Other ID Cache's in server and in the client library ignores
4776 * If the ID Cache entry's `expire' field is zero then the entry
4777 never expires. Added boolean `expire' argument to the
4778 silc_idcache_add function in the lib/silccore/idcache.[ch].
4779 If it is TRUE the default expiry value is used.
4781 * Added silc_server_free_client_data_timeout that is registered
4782 when client disconnects. By default for 5 minutes we preserve
4783 the client entry for history - for WHOWAS command.
4785 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4787 * Added support to the server to enforce that commands are not
4788 executed more than once in 2 seconds. If server receives
4789 commands from client more frequently, timeout is registered
4790 to process the commands. Affected file silcd/command.c.
4791 Added new function silc_server_command_process_timeout.
4793 * Changed NICK_NOTIFY handling in client library to check that
4794 if the client's nickname was changed, so there is no need to
4795 resolve anything from the server.
4797 * Removed error printing from the WHOIS and IDENTIFY commands.
4798 If error occurs then it is ignored silently in the client library.
4799 The application, however, may map the received error to
4800 human readable error string. The application currently maps
4801 the NO_SUCH_NICKNAME error to string.
4803 * Made the command status message public to the application. Moved
4804 them from lib/silcclient/command_reply.c to
4805 lib/silcclient/command_reply.h. The application can map the
4806 received command status to the string with the
4807 silc_client_command_status_message function.
4809 * Added check to the server to check that client's ID is same
4810 as the Source ID in the packet the client sent. They must
4813 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4815 * Added dist-bzip hook to the Makefile.am to make bzip2
4816 compressed distributions.
4818 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4820 * Server now enforces the maximum length for the nickname and
4821 the channel as protocol specification dictates. 128 bytes for
4822 nickname and 256 bytes for channel name.
4824 * Moved the WHOIS printing to the application. The client libary
4825 does not print out the WHOIS information anymore, the application
4826 must do it. Renamed silc_client_command_reply_whois_print to
4827 the silc_client_command_reply_whois_save.
4829 The client's idle time is also sent to the application now, and
4830 the idle is shown on screen.
4832 * Added silc_client_command_reply_identify_save to save the
4833 received IDENTIFY entries.
4835 * Do not check for channel private keys in message sending and
4836 reception if the channel does not have the PRIVKEY mode set.
4837 Affected file lib/silclient/client_channel.c.
4839 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4841 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4842 just surfaced after chaning the JOIN procedure.
4844 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Added silc_client_get_clients_by_list to get client entries
4847 from Client ID list, that is returned for example by JOIN
4848 and USERS command replies. The application should use this
4849 function for example when JOIN command reply is received to
4850 resolve the clients already on the channel (library does not
4851 do that anymore as USERS command reply is not used in the JOIN
4852 procedure anymore). Affected files lib/silcclient/silcapi.h and
4853 lib/silcclient/idlist.c.
4855 * JOIN command reply and USERS command reply returns now SilcBuffer
4856 pointers instead of unsigned char pointers when returning
4857 the client list and mode list.
4859 * Added <Client ID> argument to the JOIN command reply, mainly
4860 for the server to identify for which client the command was
4861 originally sent. Updated protocol specs accordingly.
4863 * Added SilcDlist private_key pointer to the SilcChannelEntry
4864 in the client to support the channel private keys. Affected
4865 file is lib/silcclient/idlist.h.
4867 * Added SilcChannelPrivateKey argument to the function
4868 silc_client_send_channel_message so that application can choose
4869 to use specific private ke if it wants to. If it is not provided,
4870 the normal channel key is used, unless private keys are set.
4871 In this case the first (key that was added first) is used
4872 as the encryption key.
4874 * Implemented the support for channel private key handling.
4875 Implemented the following functions:
4877 silc_client_add_channel_private_key,
4878 silc_client_del_channel_private_keys,
4879 silc_client_del_channel_private_key,
4880 silc_client_list_channel_private_keys and
4881 silc_client_free_channel_private_keys
4883 Affected file lib/silcclient/client_channel.c.
4885 * Added the support for the private keys in the channel message
4886 sending and encryption and in the message reception and
4887 decryption. Affected funtions are
4888 silc_client_send_channel_message and silc_client_channel_message.
4890 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Added SKE's key verify callback to the client library's
4893 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4895 * Removed the statement that server (or router) must send USERS
4896 command reply when joining to the channel so that the client
4897 knows who are on the channel. Instead, the client list and
4898 client's mode list is now sent in the JOIN command reply to the
4899 client who joined channel. This is better solution.
4901 * Added function silc_server_get_users_on_channel and function
4902 silc_server_save_users_on_channel to the silcd/server.[ch].
4904 * Removed function silc_server_command_send_users from the
4907 * Do not show topic on the client library anymore. The topic is
4908 sent in the command reply notify to the application and the
4909 application must show the topic now.
4911 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4913 * Added client searching by nickname hash into the IDENTIFY and
4914 WHOIS commands in the server as they were clearly missing from
4915 them. Affected file is silcd/command.c.
4917 * Fixed a bug in private message receiving in the client library.
4918 The remote ID was freed and it wasn't supposed, now it is
4921 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * Minor fix to the channel payload; allocate the data area, as it
4924 needs to be of specific length.
4926 * If the key agreement port is zero then the operating
4927 system will define the bound port. Affected files are
4928 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4930 * Added new function silc_channel_payload_decrypt into the file
4931 lib/silccore/silcchannel.[ch].
4933 * Moved the channel message etc, check from silc_packet_decrypt
4934 to applications. The library calls now a generic
4935 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4936 when the packet is either normal or special. This was done to
4937 allow more wide range of checking that was not allowed when
4938 the code was in library. Now applications can do virtually any
4939 checks to the packet and return to the library the decision how
4940 the packet should be processed. Affected files are
4941 lib/silccore/silcpacket.[ch].
4943 Added silc_server_packet_decrypt_check to the server and
4944 silc_client_packet_decrypt_check to the client library.
4946 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4947 to send with specified source and destination information.
4949 * Channel message delivery between routers was broken after the
4950 channel key distribution was fixed earlier. The channel key
4951 was used be to distributed to other routers as well which is not
4952 allowed by the protocol. Now this is fixed and channel keys
4953 really are cell specific and the channel message delivery between
4954 routers comply with the protocol specification.
4956 * Fixed various commands in server to check also the global list
4957 for the channel entry and not just the local list. The affected
4958 file silcd/command.c.
4960 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4962 * Added assert()s to buffer formatting and unformatting routines
4963 to assert (if --enable-debug) when error occurs. Affected
4964 file: lib/silcutil/silcbuffmt.c.
4966 * Changed to auto-reconnect to check whether the remote host is
4967 router and register the re-connect timeout if it is. It used
4968 to check that whether we are normal server, but router must do
4969 auto-reconnect with another router as well. Affected file
4972 * Removed the [<key len>] option from CMODE command as the cipher
4973 name decides the key length, nowadays. See the defined ciphers
4974 from the protocol specification.
4976 * Added [<hmac>] option to the CMODE command to define the HMAC
4977 for the channel. Added SILC_CMODE_HMAC channel mode.
4979 * Added [<hmac>] option for the JOIN command so that user can
4980 select which HMAC is used to compute the MACs of the channel
4983 * Added Hmac field to the Channel Message Payload. The integrity
4984 of plaintext channel messages are now protected by computing
4985 MAC of the message and attaching the MAC to the payload. The
4986 MAC is encrypted. Now, it is clear that this causes some
4987 overhead to the size of the packet but rationale for this is that
4988 now the receiver can verify whether the channel message decrypted
4989 correctly and also when private keys are set for the channel the
4990 receiver can decrypt the packet with several keys and check from
4991 the MAC which key decrypted the message correctly.
4993 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4994 lib/silccrypt/silccipher.[ch].
4996 * Added silc_hash_len to return the digest length into the
4997 lib/silcrypt/silchash.[ch].
4999 * Rewrote parts of Silc Channel Payload interface in the
5000 lib/silccore/silcchannel.[ch]. The encode function now also
5001 encrypts the packet and parse function decrypts it.
5003 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5005 * Fixed a minor formatting bug in the SKE's key material processing.
5006 It actually might have processed the keys wrong way resulting
5009 * Redefined the mandatory HMAC algorithms and added new algorithms.
5010 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5011 and hmac-md5 truncated to 96 bits. The mandatory is now
5012 hmac-sha1-96. Rest are optional (including the one that used
5013 to be mandatory). Rationale for this is that the truncated HMAC
5014 length is sufficient from security point of view and can actually
5015 make the attack against the HMAC harder. Also, the truncated
5016 HMAC causes less overhead to the packets. See the RFC2104 for
5019 * Added new [hmac] configuration section. The SKE used to use
5020 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5021 is of course wrong. The official names that must be proposed in
5022 the SKE are the ones defined in the protocol specification
5023 (hmac-sha1-96 for example). The user can configure any hmac
5024 using any hash function configured in the [hash] section. At
5025 least, the mandatory must be configured.
5027 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5029 * Added HMAC list to the SKE proposal list. It has now both
5030 hash algorithm list and HMAC list. This makes the protocol
5031 incompatible with previous versions. The SKE now seems to work
5032 the way it is supposed to work, for the first time actually.
5034 * Defined plain Hash algorithms to the protocol specification.
5037 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5039 * Implemented support for key agreement packets into the server.
5040 Added functions silc_server_key_agreement and
5041 silc_server_send_key_agreement. Other than these functions,
5042 server has nothing to do with this packet.
5044 * Added support for private message key packets into the server.
5045 Added functions silc_server_private_message_key and
5046 silc_server_send_private_message_key.
5050 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5051 called in the protocol's final callback instead in the END
5052 protocol state. This makes a little more sense and in the same
5053 time in client we can use the same protocol routines for normal
5054 key exchange and to key agreement packet handling as well.
5056 * Added to both client's and server's KE protocol context the
5057 SilcSKEKeyMaterial pointer to save the key material. We will
5058 bring the key material to the protocol's final callback by doing
5059 this. The final callback must free the key material.
5061 * Added SKE's packet_send callback into client's KE protocol
5062 context so that the caller can choose what packet sending function
5063 is used. This way we can use different packet sending when
5064 doing normal SKE when doing key agreement packet handling (in
5065 the key agreement packet handling we do not want to encrypt
5068 * Implemented the responder side of the key agreement routines
5069 in the client. The client can now bind to specified port and
5070 accept incoming key negotiation. The key material is passed
5071 to the application after the protocol is over.
5073 * Implemented the processing of incoming Key Agreement packet
5074 in the client. Added function silc_client_key_agreement to
5077 * Implemented the intiator side of the key agreement routines
5078 in the client. The client can now initiate key agreement with
5079 another remote client. The key material is passed to the
5080 application after the protocol is over.
5082 * Created client_keyagr.c to include all the key agreement
5085 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5086 SILC_TASK_CALLBACK except that it is not static.
5088 * Created client_notify.c and moved the Notify packet handling
5089 from the client.[ch] into that file.
5091 * Created client_prvmsg.c and moved all private message and
5092 private message key routines from the client.[ch] into that file.
5094 * Create client_channel.c and moved all channel message and
5095 channel private key routines from the client.[ch] into that file.
5097 * Changed silc_client_get_client_by_id_resolve to resolve with
5098 WHOIS command instead of IDENTIFY command, in the file
5099 lib/silclient/idlist.c.
5101 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5103 * Implemented the SKE's responder side to the Client library.
5105 * When FAILURE is received to the protocol do not trust it
5106 blindly. Register a timeout to wait whether the remote closes
5107 the connection as it should do it, only after that process the
5108 actual failure. This was changed to both client and server.
5110 * Added client_internal.h to include some of the structures
5111 there instead of client.h in lib/silcclient/.
5113 * Added function silc_task_unregister_by_callback to unregister
5114 timeouts by the callback function.
5116 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5118 * Some "Incomplete WHOIS info" errors has been appearing on the
5119 log files. Took away the entry->userinfo check from WHOIS
5120 reply sending. The entry->userinfo is now " " if client did not
5121 provide one. I thought this was fixed earlier but something
5122 is wrong still. Let's see if the error still appears.
5124 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5126 * Fixed a minor bug in the login when the channel key is
5127 re-generated in the server. It used to generate the key in
5128 wrong order and thus caused problems in the channel traffic.
5130 * Fixed a minor bug in channel key distsribution after
5131 KICK command. The key was not sent to the router even though
5134 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * Added silc_ske_process_key_material_data as generic routine
5137 to process any key material as the SILC protocol dictates. The
5138 function is used by the actual SKE library but can be used by
5139 applications as well. This relates to the private message keys
5140 and the channel private keys since they must be processed the
5141 same way the normal SILC session keys. The protocol dictates
5142 this. Affected files: lib/silcske/silcske.[ch].
5144 Added also silc_ske_free_key_material to free the
5145 SilcSKEKeyMaterial structure.
5147 * Defined silc_cipher_set_key function to set the key for
5148 cipher without using the object's method function. The affected
5149 files: lib/silccrypt/silccipher.[ch].
5151 * Implemented silc silc_client_add_private_message_key,
5152 silc_client_add_private_message_key_ske,
5153 silc_client_del_private_message_key,
5154 silc_client_list_private_message_keys and
5155 silc_client_free_private_message_keys functions in the
5158 Added functions silc_client_send_private_message_key to send
5159 the Private Message Key payload and silc_client_private_message_key
5160 to handle incoming Private Message Key payload.
5162 * Added Cipher field to the Private Message Key payload to set
5163 the cipher to be used. If ignored, the default cipher defined
5164 in the SILC protocol (aes-256-cbc) is used.
5166 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5168 * Removed lib/silcclient/ops.h file.
5170 Redefined parts of the SILC Client Library API. Created new
5171 file silcapi.h that deprecates the ops.h file and defines the
5172 published Client Library API. Defined also private message key
5173 API and channel private key API into the file.
5175 This is the file that the application must include from the
5176 SILC Client Library. Other files need not be included by
5177 the application anymore.
5179 * Added new key_agreement client operation callback and also
5180 defined the Key Agreement library API for the application.
5182 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5185 is used by clients to request key negotiation between another
5186 client in the SILC network. If the negotiation is started it
5187 is performed using the SKE protocol. The result of the
5188 negotiation, the secret key material, can be used for example
5189 as private message key.
5191 Implemented the Key Agreement payload into the files
5192 lib/silccore/silauth.[ch].
5194 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Redefined ciphers for the SILC protocol. Added some new ciphers
5197 and defined the key lengths for the algorithms. Changed the
5198 code accordingly. The default key length is now 256 bits.
5200 * Fixed SKE key distribution function silc_ske_process_key_material
5201 when the key length is more than 128 bits. The default key
5202 length in SILC is now 256 bits.
5204 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5205 to indicate unsupported algorithm.
5207 * Renamed rijndael.c to aes.c and all functions as well.
5209 * Fixed a long standing channel key setting bug in client library.
5210 Weird that it has never surfaced before.
5212 * Fixed bug in channel deletion. If the entire channel is removed
5213 then it must also delete the references of the channel entry
5214 from the client's channel list as the client's channel entry and
5215 the channel's client entry share same memory.
5217 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5219 * Implemented CONNECT and SHUTDOWN commands in the client.
5221 * Implemented CLOSE command to the client.
5223 * Added the function silc_idlist_find_server_by_name into the
5224 files silcd/idlist.[ch].
5226 Added the function silc_idlist_find_server_by_conn into the
5227 files silcd/idlist.[ch].
5229 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5231 * DIE command was renamed to SHUTDOWN. Updated the both code
5234 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5235 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5237 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5240 * Added function silc_server_create_connection function to create
5241 connection to remote router. My server implementation actually
5242 does not allow router to connect to normal server (it expects
5243 that normal server always initiates the connection to the router)
5244 so the CONNECT command is only good for connecting to another
5247 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5250 or some other client was kicked from the channel.
5252 Implemented the handling of the notify type to both client
5255 Implemented silc_server_send_notify_kicked to send the KICKED
5256 notify. It is used to send it to the server's primary router.
5258 * Implemented the KICK command into server and client.
5260 * Added `query' argument to the silc_idlist_get_client function
5261 to indicate whether to query the client from server or not if
5264 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5265 to indicate that the client is not channel founder.
5269 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * Removed the rng context from SilcPacketContext structure and
5272 changed that the packet routine uses the Global RNG API.
5274 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5276 * Added support for quit message that client can "leave" on the
5277 channel when it quits the SILC. It is ditributed inside the
5278 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5280 Added silc_server_free_client_data that will take the
5281 signoff message as argument.
5283 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5285 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5287 * Updated parts of the protocol specification to keep it up
5290 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5292 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5293 payloads in one packet.
5295 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5296 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5297 use now the new List flag.
5299 * Also deprecated the following packet types: REPLACE_ID,
5300 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5302 * Added list support for Notify packet in server.
5304 * Added silc_server_send_notify_channel_change to send the
5305 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5306 the silc_server_send_replace_id.
5308 * Added silc_server_send_notify_nick_change to send the
5309 NICK_CHANGE notify type. Deprecates the function
5310 silc_server_send_replace_id.
5312 * Added silc_server_send_notify_join to send the JOIN notify type.
5313 Deprecates the function silc_server_send_new_channel_user.
5315 * Added silc_server_send_notify_leave to send LEAVE notify type.
5316 Deprecates the function silc_server_send_remove_channel_user.
5318 * Added silc_server_send_notify_cmode and
5319 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5320 types. Deprecates the silc_server_send_set_mode function.
5322 * Added SERVER_SIGNOFF notify type to indicate that server has
5323 quit. This means that all clients on the channel from that
5324 server will drop. This can be also used when netsplit happens.
5326 Deprecated REMOVE_ID packet type since it is not needed anymore
5329 Added silc_server_send_notify_server_signoff to send the
5330 SERVER_SIGNOFF notify type. Deprecates the function
5331 silc_server_send_remove_id.
5333 Added also silc_server_send_notify_signoff to send the
5334 SIGNOFF notify type.
5336 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5337 SILC protocol from this day on. Changed the protocol
5338 specification as well.
5340 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5341 notify type. It is used between routers to notify about
5342 topic changes on a channel.
5344 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5347 * Partly updated the protocol specification to comply with the
5348 changes now made. It is still though a bit outdated.
5350 * The JOIN notify type now takes one extra argument <Channel ID>.
5351 The packet used to be destined to the channel but now the
5352 JOIN type may be sent as list thus it is impossible to
5353 destine it to any specific channel. By adding this argument
5354 it is again possible.
5356 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5358 * Added CREDITS file. The CHANGES and CREDITS file will appear
5359 in the distribution as well.
5361 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5363 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5364 types in the server's silcd/packet_receive.c.
5366 * Implemented CMODE and CUMODE to work in router environment.
5368 * Fixed minor encoding and decoding buglet from the
5369 lib/silccore/silcmode.c.
5371 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5374 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5376 * Changed all SilcConfigServer* and silc_config_server* to
5377 SilcServerConfig* and silc_server_config*, respectively.
5380 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5382 * Associated the ID (client or server ID) to the Authentication
5383 Payload to avoid any possibility of forging. Updated the
5384 protocol specification and the code accordingly.
5386 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5388 * The RSA key length is now save to the RsaKey context in the
5389 key generation process in lib/silccrypt/rsa.c. The key length
5390 is now used to figure out the maximum size of the block allowed
5391 to be encrypted/signed.
5393 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5394 is equivalent to the silc_mp_mp2bin but does not allocate any
5397 * Changed silc_mp_mp2bin API to take length argument. If it is
5398 non-zero then the buffer is allocated that large. If zero, then
5399 the size is approximated using silc_mp_sizeinbase, which however
5402 * Created Global RNG API which is global RNG that application can
5403 initialize. After initializing, any routine anywhere in the
5404 code (including library) can use RNG without allocating a new
5405 RNG object. This was done to allow this sort of use of the
5406 RNG in code that has no chance to allocate RNG object. All
5407 applications currently allocate this and many routines in the
5408 library use this. Affected file lib/silccrypt/silcrng.[ch].
5410 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5411 it to use the Global RNG API.
5413 * Defined Authentication Payload into protocol specification that
5414 is used during SILC session to authenticate entities. It is
5415 used for example by client to authenticate itself to the server
5416 to obtain server operator privileges.
5418 Implemented this payload into the lib/silccore/silcauth.[ch].
5419 Implemented also routines for public key based authentication
5420 as the new protocol specification dictates.
5422 Moved definitions of different authentication methods from
5423 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5425 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5426 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5427 silc_pkcs_verify_with_hash functions into the file
5428 lib/silccrypt/silcpkcs.[ch].
5430 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5432 * The client entry's userinfo pointer must be always valid.
5433 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5434 will fail since it requires the userinfo. Now, the userinfo
5435 is allocated as "" if actual userinfo does not exist. Actually,
5436 it must exist and it is totally Ok to drop client connections
5437 that does not announce the userinfo. However, we will make
5438 this workaround for now.
5440 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5441 to return the remote port by socket.
5443 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5445 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5446 SILC_SERVER_PENDING_EXEC and added an new macro
5447 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5448 data or when error occurs while processing the pending command.
5450 Added new argument `destructor' into silc_server_command_pending
5451 and to the SilcServerCommandPending object. This destructor is
5452 now called after calling the pending callback or if error occurs
5453 immediately. If error occurs the actual pending callback won't
5454 be called at all - only the destructor. The destructor may be
5455 NULL if destructor is not needed.
5457 All this applies for client library code as well. Similar
5458 changes were made there as well for the pending commands.
5460 In the client, the application must now allocate the
5461 SilcClientCommandContext with the silc_client_command_alloc
5464 * Added reference counter to the SilcServerCommandContext. Added
5465 function silc_server_command_alloc and silc_server_command_dup
5468 Same type of functions added to the client library for the same
5471 * Removed the cmd_ident from IDListData away since it is now
5472 global for all connections. It is the command identifier used
5473 in command sending and with pending commands. The affected file
5476 * Added reference counter to the SilcSocketConnection objecet to
5477 indicate the usage count of the object. The object won't be
5478 freed untill the reference counter hits zero. Currently only
5479 server uses this, and client ignores it. The client must be
5480 set to use this too later. The affected files are
5481 lib/silccore/silcsockconn.[ch]. Added also the function
5482 silc_socket_dup to increase the reference counter.
5484 This was mainly added because it is possible that the socket
5485 is removed underneath of pending command or other async
5486 operation. Now it won't be free'd and proper DISCONNECTING
5487 flags, etc. can be set to avoid sending data to connection that
5488 is not valid anymore.
5490 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5491 the connection. After that it sets SILC_SET_DISCONNECTED.
5492 It is, however, possible that the socket data is not still freed.
5493 The silc_server_packet_process now checks that data is not
5494 read or written to connection that is DISCONNECTED. The socket
5495 get's freed when the reference counter hits zero.
5497 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5499 * Changed the client operation API: channel_message operation's
5500 `sender' is now the client entry of the sender, not the nickname
5501 and the `channel' is the channel entry, not the channel name.
5503 In the private_message operation the `sender' is now also the
5504 client entry of the sender not the nickname.
5506 Affected file is lib/silcclient/ops.h and all applications
5507 using the client operations.
5509 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5511 * Moved the calling of ops->connect() from connect_to_server_final
5512 into receive_new_id functin since that is the point when the
5513 client is actually allowed to send traffic to network. The
5514 affected file is lib/silcclient/client.c.
5516 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5518 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5519 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5520 (if needs broadcasting) instead of broadcasting the packets one
5521 by one which would make a burst in the network traffic.
5523 * Added `broadcast' argument to the functions in silcd/server.[ch]
5524 silc_server_create_new_channel[_with_id] to indicate whether
5525 to send New Channel packet to primary router.
5527 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5529 * Added new function into the silcd/server.[ch] files:
5530 silc_server_create_new_channel_with_id to create new channel with
5531 already existing Channel ID.
5533 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5534 lib/silccore/silcpacket.h. This packet is used t send list of
5535 Set Mode payloads inside one packet. Server uses this to set
5536 the modes for the channels and clients on those channels, that it
5537 announced to the router when it connected to it. The protocol
5538 specification has been updated accordingly.
5540 * The silc_server_new_channel did not handle the packet coming
5541 from normal server as it normally does not send that. However,
5542 when it announces its channels it does send it. Implemented
5543 the support for that.
5545 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5546 into the file lib/silccore/id.h.
5548 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5550 * Fixed memory leaks in the functions silc_idlist_del_client,
5551 silc_idlist_del_channel and silc_idlist_del_server in the file
5552 silcd/idlist.c. All of those leaked like a sieve.
5554 * Fixed some small memory leaks in the client's function
5555 silc_client_notify_by_server.
5557 * Added functions into silcd/server.c: silc_server_announce_clients,
5558 silc_server_announce_channels and silc_server_announce_server.
5559 These functions are used by normal and router server to announce
5560 to its primary router about clients, channels and servers (when
5561 router) that we own. This is done after we've connected to the
5564 These functions effectively implements the following packet types:
5565 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5566 and SILC_PACKET_NEW_ID_LIST.
5568 * Added new functions into the silcd/packet_receive.[ch]:
5569 silc_server_new_id_list, silc_server_new_channel_list and
5570 silc_server_new_channel_user_list to handle the incoming
5571 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5573 * Added support of changing Channel ID in the function
5574 silc_server_replace_id. If the server that announces a channel
5575 to the router already exists in the router (with same name but
5576 with different Channel ID), router is responsible to send
5577 Replace ID packet to the server and force the server to change
5578 the Channel ID to the one router has.
5580 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5581 client that the Channel ID has been changed by the router. The
5582 normal server sends this to the client. Client must start using
5583 the new Channel ID as the channel's ID.
5585 Implemented handling of this new type into lib/silcclient/client.c
5586 into the function silc_client_notify_by_server.
5588 * Added new function silc_idlist_replace_channel_id into the files
5589 silcd/idlist.[ch] to replace the Channel ID.
5591 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5593 * Call silc_server_command_identify_check always when processing
5594 the IDENTIFY command in silcd/command.c
5596 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5599 send keepalive packets. The packet can be sent by clients,
5600 servers and routers.
5602 Added function silc_socket_set_heartbeat into the file
5603 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5604 If not set, the heartbeat is not performed. The actual
5605 heartbeat is implemented in the low level socket connection
5606 library. However, application is responsible of actually
5609 Added silc_server_send_heartbeat to send the actual heartbeat
5610 packet into silcd/packet_send.[ch]. Server now performs
5611 keepalive with all connections.
5613 * Added silc_task_get_first function into lib/silcutil/silctask.c
5614 to return the timeout task with shortest timeout. There was a bug
5615 in task unregistration that caused problems. TODO has been
5616 updated to include that task system must be rewritten.
5618 * The client library will now resolve the client information when
5619 receiving JOIN notify from server for client that we know but
5620 have incomplete information.
5622 * Rewrote parts of silc_server_remove_from_channels and
5623 silc_server_remove_from_one_channel as they did not remove the
5624 channel in some circumstances even though they should've.
5626 * Encryption problem encountered in server:
5628 The LEAVE command used to send the Channel Key packet to the
5629 router immediately after generating it. However, the code
5630 had earlier sent Remove Channel user packet but not immediately,
5631 ie. it was put to queue. The order of packets in the router
5632 was that Channel Key packet was first and Remove Channel User
5633 packet was second, even though they were encrypted in the
5634 reverse order. For this reason, MAC check failed. Now, this
5635 is fixed by not sending the Channel Key packet immediately but
5636 putting it to queue. However, this is more fundamental problem:
5637 packets that are in queue should actually not be encrypted
5638 because packets that are sent immediately gets encrypted
5639 actually with wrong IV (and thus MAC check fails). So, packets
5640 that are in queue should be encrypted when they are sent to
5641 the wire and not when they put to the queue.
5643 However, the problem is that the current system has not been
5644 designed to work that way. Instead, the packet is encrypted
5645 as soon as possible and left to the queue. The queue is then
5646 just purged into wire. There won't be any fixes for this
5647 any time soon. So, the current semantic for packet sending
5650 o If you send packet to remote host and do not force the send
5651 (the packet will be in queue) then all subsequent packets to the
5652 same remote host must also be put to the queue. Only after the
5653 queue has been purged is it safe again to force the packet
5656 o If you send all packets immediately then it safe to send
5657 any of subsequent packets through the queue, however, after
5658 the first packet is put to queue then any subsequent packets
5659 must also be put to the queue.
5661 Follow these rules and everything works fine.
5663 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5665 * Added new function silc_server_remove_clients_by_server to
5666 remove all client entries from ID list when the server connection
5667 is lost. In this case it is also important to invalidate all
5668 client entires as they hold the invalid server entry. This
5669 fixes fatal bug when server has lost connection and will reconnect
5672 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5674 * Made some sanity checks to silc_server_daemonise like to check
5675 whether the requested user and group actually exists.
5677 * Added sanity check to SKE's silc_ske_responder_finish to check
5678 that the public and private key actually is valid.
5680 * Invalidate the client's nickname when receiving Replace ID
5681 packet and the Client ID is being replaced. This means that the
5682 server will query the nickname if someone needs it (client)
5685 * Sort the ID Cache in client library when the ID Cache data
5686 has changed (needs sorting).
5688 * Do not allow for SILC client to create several connections to
5689 several servers. The client does not support windows right now
5690 and generating multiple connections causes weird behaviour.
5692 Irssi-silc client does support windows and can handle several
5693 connections without problems, see: www.irssi.org and SILC plugin.
5695 * Fixed some places where client was added to the IDList. The
5696 rule of thumb is following (in order to get everything right):
5697 If the client is directly connected local client then the
5698 `connection' argument must be set and `router' argument must be
5699 NULL to silc_idlist_add_client function. If the client is not
5700 directly connected client then the `router' argument must
5701 bet set and the `connection' argument must be NULL to the
5702 silc_idlist_add_client function.
5704 * The funtion silc_server_packet_send_local_channel actually did
5705 not check whether the client was locally connected or not. It
5706 does that now. Fixed a bug related to LEAVE command.
5708 * Fixed Remove Channel User payload parsing bug in server's
5709 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5711 * The server's silc_server_save_channel_key now checks also the
5712 global ID list for the channel as it might not be in the local
5713 list. Fixed a bug related to LEAVE command.
5715 * Is this the end of the [<unknown>] buglet that has been lurking
5716 around for a long time? A little for loop fix in server's
5717 silc_server_command_whois_parse that is used by both IDENTIFY
5718 and WHOIS command. At least, this was a clear bug and a cause
5719 of one type of [<unknown>] buglet.
5721 * WHOIS and IDENTIFY commands call the function
5722 silc_server_command_[whois/identify]_check function even if
5723 we are not router server.
5725 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5727 * Added --with-gmp configuration option. If set the GMP
5728 is always compiled in the SILC source tree. If not set then
5729 it is checked whether the system has the GMP3 installed. If
5730 it has then the GMP won't be compiled (the system's headers
5731 and library is used), if it doesn't have it then the GMP is
5732 compiled in the SILC source tree.
5734 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5736 * Changed RSA private exponent generation to what PKCS #1
5737 suggests. We try to find the smallest possible d by doing
5738 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5739 not security fix but optimization.
5741 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5743 * Added new config entry [Identity] to fork the server and run
5744 it as specific user and group. A patch from Bostik.
5746 * Imported Dotconf configuration library into lib/dotconf.
5747 This will be used to create the SILC configuration files later.
5748 It will appear in the distsribution after this commit.
5750 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5752 * A big code auditing weekend happening. Auditing code for
5753 obvious mistakes, bugs and errors. Also, removing any code
5756 Removed files for being obsolete:
5758 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5759 inline in the file lib/silcutil/silcbuffer.h)
5761 o lib/silcutil/silcbufutil.c (the header has inline versions)
5763 Changed code to fix possible error conditions:
5765 o The buffer formatting routines now check that the destination
5766 buffer really has enough space to add the data. This applies for
5767 both buffer formatting and unformatting
5768 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5769 unformatting was changed to accomodate following rules:
5770 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5771 sent to the function while XXX_*STRING will not allocate or copy
5772 the data into the buffer. Instead it sets the pointer from the
5773 buffer into the pointer sent as argument (XXX_*STRING used to
5774 require that the pointer must be allocated already). This change
5775 makes this whole thing a bit more consistent and more optimized
5776 (note that the data returned in the unformatting with XXX_*STRING
5777 must not be freed now). The routines return now -1 on error.
5779 o Tried to find all code that use buffer_format and buffer_unformat
5780 and added return value checking to prevent formatting and
5781 especially unformatting errors and possible subsequent fatal
5784 o Changed ske->x and ske->KEY to mallocated pointers in
5785 lib/silcske/silcske.h. Fixed possible data and memory leak.
5787 o Added return value checking to all *_parse* functions. Fixed
5788 many memory leaks as well.
5790 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5791 so that buffer overflows would not happen. All code now also
5792 checks the return value as it can fail.
5794 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5796 * Added reconnection support to server if the normal server looses
5797 its connection to the router (for example if router is rebooted).
5798 The server performs normal reconnection strategy implemented
5799 to the server. Affected file silcd/server.c.
5801 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5803 * Added new packet type SILC_PACKET_SET_MODE that is used to
5804 distribute the information about changed modes (for clients,
5805 channels and clients channel modes) to all routers in the
5806 network. Updated the protocol specification accordingly.
5808 Added functions into silcd/packet_send.c and
5809 silcd/packet_receive.c: silc_server_send_set_mode,
5810 silc_server_set_mode.
5812 Added new files silcmode.[ch] into lib/silccore that implements
5813 the encoding and decoding of Set Mode Payload. Added new type
5814 SilcSetModePayload. Moved the definitions of different modes
5815 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5817 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5819 * Oops, a little mistake in server's connection authentication
5820 protocol. The protocol is not ended with FAILURE but with
5821 SUCCESS if the authentication is Ok. :) Affected file is
5824 * Implemented NICK_CHANGE notify handling in server in the file
5825 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5826 the local clients on the channel. After the changing nickname
5827 in router environment snhould work and the [<unknown>] nickname
5828 should appear no more.
5830 The silc_server_replace_id function that receives the Replace ID
5831 payload now sends the NICK_CHANGE notify type also in the file
5832 silcd/packet_receive.c
5834 * Changed WHOIS and IDENTIFY command to support the maximum amount
5835 of arguments defined in protocol specs (3328 arguments). This
5836 fixed a bug that caused problems when there were more than three
5839 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5841 * Added extra parameter, command identifier, to the
5842 silc_client_send_command so that explicit command identifier
5845 Changed that ID list routines uses specific command identifier
5846 when sending WHOIS/IDENTIFY requests to the server so that they
5847 can be identified when the reply comes back.
5849 Affected files lib/silcclient/command.[ch],
5850 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5852 * Added `sender' argument to silc_server_packet_send_to_channel
5853 to indicaet the sender who originally sent the packet to us
5854 that we are now re-sending. Ignored if NULL. Affected file
5855 silcd/packet_send.[ch].
5857 * Added some server statistics support in silcd/server_internal.h
5858 SilcServerStatistics structure and around the server code. Also
5859 send some nice statistics information when client is connecting
5862 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5864 * Fixed channel ID decoding in server's JOIN command reply in
5865 silcd/command_reply.c
5867 * Fixed braodcasting of replace ID payload to not to send it if
5868 we are standalone server in silcd/packet_receive.c.
5870 * Fixed all channel message sending routines to not to send
5871 packets to clients that has router set, since they are routed
5872 separately in the same function earlier. Affects file
5873 silcd/packet_send.c and all channel packet sending functions.
5875 * In USERS reply, res_argv[i] are not allocated, the table
5876 is allocated. Thus changed that free the table, not its
5879 * In server's whois_check and identify_check if the client is
5880 locally connected do not send any WHOIS commands - they are not
5883 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5885 * Fixed some minor bugs in client when sending WHOIS command. The
5886 arguments was in wrong order.
5888 * Removed statis function add_to_channel from server in
5889 silcd/command.c that was previously used with the joining but
5892 * Tested USERS command in router environment successfully with two
5893 routers, two servers and two clients.
5895 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5897 * Reorganized the USERS command and command reply in client library
5898 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5899 When the command is given by user we register a pending command
5900 callback that will reprocess the command after the reply has been
5901 received from the server. When reprocessing the packet we then
5902 display the information. Thus, the USERS information is displayed
5903 now in the command callback instead of in the command reply
5904 callback. The processing of the command is same as previously
5905 when server has sent the command reply in the JOINing process.
5907 * Added to USERS command in silcd/command_reply.c to join the client,
5908 we didn't use to know about, to the channel after we've created
5909 a client entry for it. Also, for clienet we did know already still
5910 check whether it is on the channel or not and add it if not.
5912 * Removed silc_server_command_join_notify as the function and its
5915 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5917 * Changed the client's pending command handling to the same as the
5918 server's pending command handling. It is also now possible to
5919 execute command reply functions from other command reply
5920 function as the function callbacks for commands and command
5921 replies are one and same. The pending commands are not static
5922 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5923 in client connection context. Thus, pending commands are server
5924 connection specific as it is convenient.
5926 Changed the function silc_client_command_pending and
5927 silc_client_command_pending_del and added new function
5928 silc_client_command_pending_check. Removed the
5929 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5932 * Added cmd_ident, current command identifier, to the client
5933 connection context in lib/silcclient/client.h to keep track on
5934 command identifiers used in command sending. Client's command reply
5935 function handling now supports the mandatory command identifiers.
5937 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5938 funtions in client to fully support pending command callbacks.
5940 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5941 as one of the arguments to the application in the command reply
5944 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5945 before first releasing SILC but came back. Now it is removed again
5946 and should come back nomore. The FORWARDED flag was used only
5947 by the JOINing procedure by forwarding the command packet to router.
5948 Now, the JOINing procedure has been changed to more generic (due
5949 to various router environment issues) and FORWARDED is not needed
5950 anymore for anything. The protocol specification is yet to be
5953 Now, removed silc_server_packet_forward from server and the flag
5954 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5956 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5958 * Renamed NAMES command to USERS command. The NAMES was named that
5959 due to historical reasons. Now it is renamed. Also, rewrote
5960 parts of the USERS command. The nickname list is not sent anymore
5961 by the server. Only Client ID and mode lists are sent in the USERS
5962 command. Changed this also to the protocol specification.
5964 The client now resolves the names and stuff after it receives
5965 the USERS list from the server when joining to the channel.
5967 * WHOIS and IDENTIFY commands has been changed to support multiple
5968 Client ID's per command. One can now search for multiple users
5969 in the network by sending only one WHOIS or IDENTIFY command.
5970 Changed the code and the protocol specifications.
5972 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5973 uses silc_server_command_whois_parse to parse the request. */
5975 * If normal server, do not parse the WHOIS and IDENTIFY requests
5976 before sending it to the router. Saves some time.
5978 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5980 * Fixed JOIN command on client library. Wrong number of arguments
5981 used to crash the client.
5983 * Added silc_server_channel_has_global function to check whether
5984 channel has global users or not.
5986 * Added silc_server_channel_has_local function to check whether channel
5987 has locally connected clients on the channel.
5989 * The silc_server_remove_from_one_channel now checks whether the
5990 channel has global users or not after given client was removed from
5991 the channel. It also checks whether the channel has local clients
5992 on the channel anymore. If it does not have then the channel entry
5993 is removed as it is not needed anymore.
5995 * The silc_server_notify now checks on JOIN notify whether the joining
5996 client is one of locally connected or global. If it is global then
5997 the channel has now global users on the channel and that is marked
5998 to the channel entry. Also, it now saves the global client to
5999 global list who is joining and JOINs it to the channel. This is
6000 for normal server, that is.
6002 Changed silc_server_send_notify_on_channel,
6003 silc_server_packet_relay_to_channel and
6004 silc_server_packet_send_to_channel check if we are normal server
6005 and client has router set (ie. global client) do not send the
6006 message to that client, as it is already routed to our router.
6008 * Implemented LEAVE notify type handling in silc_server_notify
6011 * Tested LEAVE command in router environment successfully. Tested
6012 with two routers, two servers and two clients.
6016 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6018 * Implemented SIGNOFF notify type handling in silc_server_notify
6021 * silc_server_remove_id now removes the client entry from all channels
6022 it has joined and thusly sends SIGNOFF notify type.
6024 * Rewrote the NAMES list generation in server by removing two excess
6025 loops. The lists are created now inside one loop.
6027 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6029 * silc_server_remove_channel_user checks now also global list
6030 for channel and client.
6032 * silc_server_new_channel_user checks now both local and global
6033 list for channel and client. Fixed a bug in client id decoding.
6034 Used to decode wrong buffer.
6036 * silc_server_channel_message checks now both local and global
6037 list for channel entry.
6039 * Tested channel joining (hence JOIN) in router environment
6040 successfully. Tested with two routers, two servers and two
6043 * Tested channel message sending in router environment successfully.
6045 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6047 * Added silc_server_save_channel_key into server.[ch] to save the
6048 received channel key in Channel Key payload processing. It is
6049 also used in JOIN command reply handling.
6051 Equivalent function silc_client_save_channel_key added into
6052 client.[ch] into client library.
6054 * Changed JOIN command reply to send information whether the channel
6055 was created or not (is existing already) and the channel key
6056 payload. Changed protocol specs accordingly.
6058 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6059 the request was sent by ID and not by nickname. Crashed on
6062 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6064 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6065 now correctly save the received data.
6067 * silc_server_free_sock_user_data now notifies routers in the
6068 network about entities leaving the network.
6070 At the same time implemented functions silc_server_remove_id
6071 and silc_server_send_remove_id to receive and send REMOVE_ID
6072 packets. The packet is used to notify routers in the network
6073 about leaving entities. The ID removed will become invalid in
6076 * Added function silc_idlist_del_server into server. Removes and
6077 free's server entry from ID list.
6079 * silc_server_private_message function now checks, if we are router,
6080 that the destination ID really is valid ID, naturally.
6082 * In router when NEW_ID packet is received (for new client) the
6083 hash of the Client ID is saved in the ID Cache but the
6084 client->nickname is set to NULL, instead of putting the hash
6087 IDENTIFY command now also checks that client->nickname must be
6088 valid. If it is not if will request the data from the server who
6089 owns the client. Added new function
6090 silc_server_command_identify_check.
6092 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6093 to set the command to already allocated Command Payload.
6095 * Tested private message sending in router environment with two
6096 routers, two servers and two clients. Fixed minor bugs and now
6099 * Fixed segfault from client's NAMES command. Used to crash if
6102 * Forwarded packets must not be routed even if it is not destined
6103 to the receiver. Changed server code comply with this.
6105 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Added `require_reverse_mapping' boolean value to ServerParams
6108 structure. If TRUE (not default) the server will require that
6109 the connecting host has fully qualified domain name.
6111 If the reverse mapping is not required and hostname could not be
6112 found the IP address is used as hostname.
6114 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6116 * Implemented version string checking to both client and server.
6117 The check is incomplete currently due to the abnormal version
6118 strings used in development version of SILC.
6120 * Changed all command functions in server to use the new
6123 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6125 * Changed char *data to unsigned char *data in ID Cache system to
6126 support binary data as ID Cache data. Changed code to support
6127 binary data in lib/silccore/idcache.c.
6129 * Renamed silc_server_packet_relay_command_reply to
6130 silc_server_command_reply as it is normal packet receiving
6131 function. Rewrote the function to accept command replys for
6132 servers and not only for clients.
6134 * Mark remote router always as registered server if we are connecting
6135 to it. Otherwise, commands sent by the router to us are ignored.
6137 * All ID List find routines now returns the ID Cache Entry pointer
6138 as well if requested.
6140 * WHOIS command works now in router environment, tested with two
6141 routers, two servers and two clients.
6143 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6144 in router environment (as it is almost equivalent to WHOIS) but
6145 hasn't been tested thoroughly. Added new functions:
6147 silc_server_command_identify_parse
6148 silc_server_command_identify_send_reply
6149 silc_server_command_identify_from_client
6150 silc_server_command_identify_from_server
6152 * Disabled route cache adding because adding two different ID's with
6153 same IP replaces the old cache entry thus giving wrong route.
6154 The entry->router->connection is always the fastest route anyway
6155 so route cache may not be needed. Of course, new routes maybe
6156 established after receiving the ID when the entry->router->connection
6157 might not be anymore the most optimal.
6159 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6161 * Add route cache for received ID for fast routing.
6163 * Added silc_server_packet_route to route received packet on router
6164 that is not destined to us.
6166 * Renamed silc_server_get_route to silc_server_route_get.
6168 * Added id_string and id_string_len fields into SilcServer to
6169 include encoded ServerID for fast comparing without excess
6170 encoding of the ID's.
6172 * Cleaned up WHOIS command on server side. Added following static
6175 silc_server_command_whois_parse
6176 silc_server_command_whois_check
6177 silc_server_command_whois_send_reply
6178 silc_server_command_whois_from_client
6179 silc_server_command_whois_from_server
6181 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6182 arguments in command replies. All command functions should be
6183 updated to use this macro.
6185 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6187 * Minor typo fixes on command reply handling on server.
6189 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6191 * Added silc_server_command_add_to_channel internal routine to add
6192 the client to the channel after router has created the channel and
6193 sent command reply to the server.
6195 * Added generic silc_server_send_command to send any command from
6198 * Use static buffer with ID rendering instead of duplicating data.
6200 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6202 * Fixed a channel user mode bug when joining to a channel server gave
6203 everybody channel founder rights, oops.
6205 * We mark ourselves as the router of the incoming server connection
6206 if we are router ourselves. This way we can check in some packet
6207 sending functions whether it is locally connected server. For
6208 incoming router connections we put NULL.
6210 * For router sending packets locally means now always sending the
6211 packet cell wide; to local clients and local servers. For normal
6212 server sending packet locally means sending it to only local
6215 * Fixed the JOIN command to really work in router environment. If the
6216 channel is created it is always created by the router. Router is
6217 also responsible of making the initial joining to the channel,
6218 sending JOIN notify to the sending server and distributing
6219 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6220 does not exist server doesn't do anything else but forward the
6221 command to the router which performs everything.
6223 * Added silc_server_send_channel_key function to send the Channel Key
6226 * Added silc_server_create_channel_key to create new channel key. The
6227 channel key is now re-generated everytime someone joins or leaves
6228 a channel, as protocol dictates. Note: channel->key_len is the
6231 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6233 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6234 packet_receive.[ch] to separate packet sending and receiving
6235 routines. The server.[ch] now includes everything else including
6236 actual packet processing (writing and reading data) and other
6239 Renamed silc_server_private_message_send_internal to
6240 silc_server_send_private_message. The routine is still though
6241 used only to relay private messages as server does not send
6242 private messages itself.
6244 Renamed silc_server_new_channel to silc_server_create_new_channel
6245 and added new function sicl_server_new_channel that handles the
6246 incoming New Channel packet. Added also new sending function
6247 silc_server_send_new_channel to send New Channel Payload.
6249 * Added new function silc_server_notify to process incoming notify
6250 packet to the server/router. Server may then relay the notify
6251 to clients if needed.
6253 * Added new function silc_server_new_channel_user to process incoming
6254 New Channel User packet. Router will redistribute the packet and
6255 send JOIN notify to its local clients and locally connected servers
6256 if needed. Normal server will send JOIN notify to its local client
6257 on same channel when received this packet. Added also corresponding
6258 sending function silc_server_send_new_channel_user to sent the
6261 * Added boolean route argument to send_notif_to_channel and
6262 packet_send_to_channel functions to attempt to route the packet
6263 if it is TRUE and send only locally if it is FALSE.
6265 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6267 * silc_server_replace_id now broadcasts the received replace ID
6268 packet if it is not broadcast packet already. The router must
6269 broadcast to inform other routers about changed ID.
6271 * Added backpointer to server's router into SilcServer context in
6272 silcd/server_internal.h.
6274 * Fixed silc_server_packet_broadcast to send correct broadcast
6277 * The channel key is now distributed to the local client as soon
6278 as it is received from the router (in router environment) so that
6279 no other packet may be sent for the channel until client has
6282 * silc_server_remove_channel_user now broadcasts the received
6283 Remove Channel User packet if it is not broadcast packet already.
6284 The router must broadcast to inform other routers about removed
6287 * Added users field into SilcPacketContext that is a reference count
6288 of the context. One can increase the reference count by calling
6289 silc_packet_context_dup which is now changed to just increase the
6290 reference count instead of duplicating the data. The reference
6291 count is decresed by calling silc_packet_context_free that will
6292 free the data after the reference count hits zero.
6294 For now on the packet context and everything allocated into it
6295 (including the raw packet from network) must be freed by calling
6296 the new silc_packet_context_free function. Added also new function
6297 silc_packet_context_alloc that must be used now to allocate the
6298 context. This also means that if a routine is asynchronous from
6299 silc_[client/server]_packet_parse_type the packet context must
6300 be duplicated by calling silc_packet_context_dup. Otherwise it
6301 gets free'd after silc_[client/server]_packet_parse_type returns.
6302 Also, one must remember that if packet is duplicated then its
6303 reference count must be decresed by calling the free function as
6304 many times as it was duplicated.
6306 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6307 from both client and server.
6309 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6311 * Made joining to a channel working in router environment.
6313 * Cleaned up JOIN command on server side and create function
6314 silc_server_command_join_channel internal routine to make the
6317 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6319 * Changed silc_command_pending list to SilcDList. Also, added
6320 `ident' field to SilcServerCommandPending structure to identify
6321 the reply and to call correct callback.
6323 Added silc_server_command_pending_check function to replace the
6324 corresnponding macro. The silc_command_pending list is not
6327 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6328 to set identifier to previously allocated Command Payload. It
6329 is used to set identifier for command when resending Command
6332 * Added silc_command_payload_encode_payload to encode Command
6333 Payload buffer from SilcCommandPayload structure.
6335 * Added silc_argument_payload_encode_payload to encode Argument
6336 payload buffer from SilcArgumentPayload structure.
6338 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6340 * Changed WHOIS command to support router connection on server side.
6341 The whois request is always sent to router unless the server is
6342 standalone server. After server has received the reply from the
6343 router will it send the reply to the client.
6345 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6346 broadcast received broadcast packet. The function is used only
6347 by router. The broadcast packet is always sent to the router's
6350 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6351 render given ID to printable string, for log files for example.
6353 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6355 * Made basic router to router connections working. At least they
6356 can now connect to each other but nothing really works the way
6357 they are supposed - yet.
6359 * Added new initiator token to RouterConnection configuration
6360 file in silcd/serverconfig.[ch]. It is used to tell whether we
6361 are the initiator to the remote router or whether we'll expect
6362 the other end to connect.
6364 * Moved registering of listener task to silc_server_init, hence
6365 the server starts listenning as soon as it is run, even if it
6366 does not have connections to other routers. Let's see how well
6369 * Changed default connection retry timeouts for more suitable in
6372 * Removed cipher and such arguments from silc_idlist_add_client
6373 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6374 Added new function silc_idlist_add_data to add the keys and stuff
6377 * Added SilcIDListData structure and added it to SilcClientEntry
6378 and SilcServerEntry as their first field in the structure. This
6379 way we can explicitly cast the ID entries to the SilcIDListData
6380 structure and get common data for the entries. In past, we had
6381 to first check what type of connection it is and then cast it to
6382 correct ID entry type. Now, we can directly cast the opaque
6383 pointer to the SilcIDListData (no matter what ID entry it actually
6384 is) and get the data needed.
6386 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6388 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6389 in some circumstances even if threre were timeout tasks, though not
6390 IO tasks, but tasks anyway. Now fixed.
6392 * Defined SilcServerConnection structure to hold connection specific
6393 stuff about directly connected servers and routers. The definition
6394 is currently in silcd/server_internal.h. I thought about having
6395 a bit more important role fro this struct but for now it is used
6396 only when connecting to other server (or router actually).
6398 * Added connecting retry support in server when connecting to
6399 router(s). The retry feature implement exponential backoff
6400 algorithm. Also, added SilcServerParams structure to hold default
6401 parameters for server. For now, it include these retry settings
6402 and are hard coded. After server is moded to be as Silc Server
6403 Library this structure will be more important.
6405 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6407 * Changed client librarys channel->clients table to SilcList and
6408 changed code accordingly.
6410 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6412 * Changed client's channel table to SilcList and changed code
6413 accordingly. Also changed SilcChannelClientEntry to include back-
6414 pointer to the channel so that client entry can use that structure
6415 as list as well and we have fast cross-reference to the channel.
6416 This change dramatically decreased the complexity of channel
6417 handling with client entry and vice versa (removed one extra
6418 loop when searching for channel entry from many functions).
6420 * Changed server->sim from table to SilcDList and changed code
6423 * NAMES command can now be used from user interface. It will show
6424 the user list on the channel, neatly.
6426 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6427 Code now saves realname of the user if it becomes available.
6429 * Renamed configure.in to configure.in.pre and made ./prepare
6430 script to automatically add correct version string to
6431 configure.in which it creates from configure.in.pre.
6433 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6435 * NAMES command reply now shows users mode with the nickname when
6438 * Moved silc_client_ch[u]mode[_char] functions from
6439 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6440 place sucks, they are utility functions and should be in some
6443 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6445 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6448 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6452 * Added TRQ (efficient deque and list library) into lib/trq. This is
6453 a very good list library that is currently used in the SILC. Defined
6454 SilcList API over the library because I didn't like the API very
6455 much. See lib/trq/silclist.h for the API and examples of how to
6456 use the API. Fixed various places in the code to use the new
6457 SilcList API. The SilcList is meant for lists that has a structure
6458 already defined as a list. It is not suitable to add just some
6459 context to the list (in TRQ, the context is the list actually).
6461 So, I defined SilcDList that can be used for the purpose where
6462 predefined list structure does not exit. This can be used as
6463 such list. Now some context just can be added to the SilcDList.
6464 Currently this list is not used in the SILC just yet, though there
6465 are a lot places where this can replace dynamically allocated
6466 tables and I will fix these places, later, to use SilcDList.
6467 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6468 and use TRQ internally).
6470 Also fixed some annoying warning messages that the original TRQ
6471 code generated. Also minor changes to TRQ's Makefile.in.
6473 * Added support for querying by Client ID to both WHOIS and
6474 IDENTIFY commands into server, as required by the protocol.
6476 * Removed method function pointers from SilcBuffer structure. They
6477 weren't used to anything and just increased the context size for
6478 no good reason. This change also made silc_buffer_alloc and
6479 silc_buffer_free functions inline functions.
6481 * Disabled command flooding detection support until it's fixed so
6482 that it accepts commands in but does not execute them more than once
6485 * Added silc_net_localhost(), to return local hostname, into
6486 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6487 that must be initialized before calling silc_client_init.
6489 * Added new function: silc_server_send_notify_on_channels to send
6490 notify messages to all channels client has joined. It is assured
6491 that the message is sent only once per client.
6493 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6494 lib/silcutil/silcutil.[ch] as silc_format function. The new
6495 function is generic and is used by server as well, not only by
6496 the logging routines.
6498 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6499 the provided version string was not acceptable. Added new function:
6500 silc_ske_check_version into lib/silcske/silcske.h. The function
6501 must be implemented by the application (client or server) and it
6502 does not reside in the SKE library. The function checks the version
6503 string remote end sent.
6505 * Added back pointers (to opaque context and to SilcSocketConnection)
6506 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6508 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6509 duplicate packet context structure.
6511 * Changed `notify' client operation to send same arguments as client
6512 receives from server except for ID's. ID's are mapped to correct
6513 ID entry and that is returned. Also, if channel entry is not sent
6514 by server but the notify is for channel the channel entry is sent
6515 to application (otherwise application doesn't know that it is for
6516 channel (library gets it from packet's Destination ID)).
6518 * Added silc_client_remove_from_channels into client library to
6519 remove a client from all channels it has joined to. Used when
6520 received SIGNOFF notify from server. Added also new function
6521 silc_client_replace_from_channels to replace old ID entry with
6522 new ID entry on all channels. Used when received NICK_CHANGE
6525 * Fixed ID Cache list handling in silc_idlist_get_client in
6526 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6527 to get (or query) client by ID.
6529 * Updated TODO list.
6531 * Added connection authentication status message defined by the
6532 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6533 support for these into the code in client and server side.
6535 * Added generic function silc_client_send_command to send any command
6536 with variable argument list. Application should use this function
6537 to send commands if the command functions provided by the library
6538 does not suite for the application's user interface needs.
6540 * Added new `failure' client operation. Application is notified about
6541 received failure packet if client is executing a protocol. In this
6542 case the protocol's execution has failed.
6544 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6545 is required by the protocol.
6547 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6548 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6551 * Added status flag to SilcSKE object to indicate realtime status
6552 of the SKE protocol.
6554 * Application receives now exactly same command reply arguments as
6555 the library receives from server. However, if ID is received the
6556 corresponding ID entry is returned to the application (eg. Client
6557 ID is mapped to correct SilcClientEntry entry and that is returned).
6558 Changed command_reply client operation due to this change.
6560 * Changed all ID's in commands and in command replys as ID Payloads.
6561 Change affected both client and server side codes.
6563 All ID's sent in SILC network (with execption of ID's in SILC
6564 Packet header) are sent in ID Payload to support variable length
6567 * Server now notifies nick changes and notifies all clients on
6568 the channels about the new nickname (about the new Client ID,
6571 * Implemented CMODE command to change channel modes. Supports all
6572 channel modes defined by the protocol specs except ban and invite
6573 lists. (Also, private channel key mode is supported but support for
6574 setting private channel key in client is missing, thus, this mode
6575 has no effect on client side (except that server requires that the
6576 client uses private channel key and normal channel traffic does not
6579 Also, invite mode works per se, but INVITE command does not work
6580 yet correctly, so you can set channel as invite only channel but
6581 inviting clients to the channel does not work (it is yet to be
6582 thought what's the best way to do it).
6584 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6585 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6586 Implemented CUMODE command to change user's mode on the channel.
6587 Supports all modes defined by the protocol specs.
6589 * Added NAMES command reply to return users modes on the channel.
6591 * Removed unnecessary and slow ciphers from lib/silccrypt.
6593 * Set SO_KEEPALIVE option to connection sockets by default.
6595 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6597 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6598 redefined the Notify Payload into protocol specs.
6600 * Added silc_id_payload_parse_id to get ID directly from raw
6603 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6605 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6606 accept searching by Client ID as well.
6608 * Added support for LEAVE and SIGNOFF notify types in client library.
6610 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6611 to parse ID Payload from raw data.
6613 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6615 * Added flags parameter into silc_ske_assemble_security_properties
6616 function in lib/silcske/silcske.[ch].
6618 * Changed notify client operation to fit better for notify messages
6619 sent by server. The notify payload received from server is now
6620 passed to the application (after parsing it to SilcNotifyPayload).
6621 It is application's responsibility to retrieve the arguments
6622 from the payload and show the message the way it wants. The message
6623 sent by server is implementation specific.
6625 * Changed public keys to comply with the protocol specification.
6626 Old public keys are not supported anymore and are not compatible.
6628 * Removed nickname from Channel Payload as the latest draft removed
6629 it. The client must resolve the nickname from the NAMES command
6630 reply received when it joined the channel.
6632 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6634 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6636 * Fixed some errors in protocol specification drafts.
6638 * Created lib/silccore/silcnotify.c to implement Notify Payload
6639 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6640 generic payloads described by protocol specifications. The file
6641 includes implementations for ID Payload and Argument Payload.
6643 * Changed Command Payload implementation to use the new Argument
6644 Payload. Changed command_xxxx_payload to command_payload_xxxx
6645 to comply with SILC coding conventions.
6647 * Added suppport for Argument Payload handling in Notify Payload
6648 implementation as protocol requires it. Added the new support
6649 into server and client lib as well.
6651 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6653 * Added support for multiple nicknames on same channel. [n] is
6654 added locally to the nickname if there are more than one same
6655 nicknames on the channel.
6657 * Server now sends all nicknames that matched WHOIS request.
6658 Client also shows the list received from server.
6660 * Added TOPIC command to client side. User can now set and show
6661 current topic on channel.
6663 * Added MOTD command to client and server. Also, server sends the
6664 motd when client connects to the server.
6666 * Changed version strings to comply ISO 8601.
6668 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6670 * Fixed protocol error handling in client library. It should now
6671 cope even if the SKE fails for some reason.
6673 * Made new protocol specification drafts for submitting to IETF.
6675 * Implemented TOPIC command to server in silcd/command.c.
6677 * Added two new notify types into lib/silccore/silcnotify.h:
6678 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6679 notify nickname change and topic setting/change on a channel.
6681 * API change of command_reply operation in client library. The
6682 application gets now the status type received from server as well.
6684 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6686 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6688 * Cras fixed and optimized the packet handling even further and
6689 it should work now. Minor change to the prototype of function
6690 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6692 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6694 * Added new function into lib/silcutil/silcschedule.[ch]:
6695 silc_schedule_with_fd to select() a specified fd. The function
6696 returns after timeout expires or data arrives or goes. The
6697 function is used by packet routines to wait that all data is
6698 received from network.
6700 * Fixed data reading from network in lib/silccore/silcpacket.c.
6701 The code now assures that all data is read from the fd and then
6702 continues packet processing. This was a bug fix since the code
6703 used to drop some data in some circumstances.
6705 * Added new function into lib/silcclient/client.[ch]:
6706 silc_client_start_key_exchange to start key exchange after
6707 connection has been established to server. The code internally
6708 now uses this funtion but its main purpose was to provide it
6709 for applications that perform their own connecting. After
6710 application has created a connection it merely calls this
6711 function to start the key exchange between client and server.
6712 The library takes care of everything else after that.
6714 Updated also lib/silcclient/README to explain the usage of
6717 * Do not send to application information that connection has
6718 been established. Application gets notified it by connect
6721 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6723 * Applied cras's patch to add silc_schedule_one function. The
6724 function runs scheduler once and returns.
6726 * Fixed the scheduler after cras messed it up. The timeout
6727 handling works now as it's supposed to work.
6729 * Added into lib/silccore/ silcnotify.h to include notify
6730 message types support. Changed silc_server_send_notify*
6731 functions, in server.[ch], to support those new notify types.
6732 Added the support for the notify types into client library,
6733 as well. Added new notify client operation into ops.h in
6736 * Changed silc_server_packet_send_to_channel to send normal
6737 packets instead of just channel message packets. The function
6738 is now used to send the notify packets to channels. It is not
6739 used to send channel message packets anymore, as server never
6742 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6743 va_arg()s as it seems to require it nowadays. I guess, if SILC
6744 is compiled with older va_arg() the new code should work anyway.
6746 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6748 * Splitted core library. Core library (lib/silccore) includes
6749 now only SILC protocol specific core (and common) components.
6750 Created new utility library (lib/silcutil) that includes more
6751 generic purpose stuff. The stuff for util library was taken
6752 from the old core library. This was minor and easy split.
6754 * Created SILC Client Library (lib/silcclient) that includes
6755 implementation of the SILC client without user interface. This
6756 was major move from silc/ directory. The code has been changed
6757 so that it is transparent towards the user interface. The
6758 silc/ directory includes now the same user interface as before
6759 and it uses the new client library. Read lib/silcclient/README.
6760 Basicly, the client library performs everything else related
6761 to SILC except user interface handling. Also, configuration
6762 files are considered to be part of user interface and library
6763 does not handle them.
6765 This change also changed a lot of structures, function naming etc.
6766 Most important change was that SilcClientWindow object was
6767 renamed to SilcClientConnection in the client library. Created
6768 also new file lib/silcclient/ops.h. Also added new files
6769 silc/local_command.[ch] and silc/client_ops.[ch].
6771 All these changes were made to make it easier for user interface
6772 designers to create what ever user interface for the SILC client
6775 It is also expected that the server will be moved to lib
6776 directory as well and SILC Server Library will be created;
6777 sometimes in the future.
6779 * Removed Local commands from lib/silccore/silccommand.h as
6780 they are application specific and new client library does not
6781 handle any of those anymore.
6783 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6784 old client implementation in silc/.
6786 * Added support for callback functions in SILC_LOG_* macros.
6787 Application can now set its own callbacks that will be called
6788 instead of using the default functions that will always print
6789 the debug messages to stderr (or stdout). Also, debugging can
6790 now be disabled by setting silc_debug to FALSE and re-enabled by
6791 setting it to TRUE. Note, that logging will still work even
6792 if debugging is disabled.
6794 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6795 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6796 silc_log_reset_debug_callbacks.
6798 * To enable debugging in silc client one must give now -d
6799 option on command line.
6801 * Changed silc_schedule_init to automatically allocate task queues
6802 if they are not allocated before calling it.
6804 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6806 * Added GMP 3.1 into math library.
6808 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6810 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6811 a channel in SILC network. The packet is used by servers and
6812 routers to notify other routers that user has left a channel.
6813 This little feature was missing until now. Added the feature
6814 to protocol specification as well.
6816 Added functions: silc_server_send_remove_channel_user and
6817 silc_server_remove_channel_user into server.[ch].
6819 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6820 lib/silccore/silcpacket.h. However, they are not implemented
6823 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6825 * Fixed joining to a channel and sending channel messages
6826 between server and router. The channel message sending should
6827 now work inside a cell.
6829 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6831 * Fixed the private message sending between server and router.
6832 The private message sending should now work inside a cell.
6834 * Added silc_server_replace_id into server.[ch] to replace
6835 existing ID in the SILC network.
6837 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6838 and silc_idlist_replace_server_id into idlist.[ch] in server.
6840 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6842 * Fixed the server to server connections. Server can again now
6843 connect to router. Router to router connections probably does
6846 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6848 * Added dynamic protocol registering support. Now protocols can
6849 registered and unregistered on the fly. Patch by cras.
6851 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6853 * Added lib/contrib directory to hold routines that some platforms
6854 don't have but are needed by SILC.
6856 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6857 into lin/contrib to provide getopt() and getopt_long() for
6858 those who don't have it.
6860 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6862 * Added AWAY command to client. When away message is set and
6863 client receives a private message packet the client automatically
6864 replies to the sender with the away message.
6866 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6867 bug seemed to be the cause of recent problems when compiling
6870 * Added version detection support to SKE protocol specification
6871 and added the new changes to the SKE implementation as well.
6872 There were other minor changes in the SKE protocol as well.
6874 Many changes in lib/silcske/silcske.[ch] and in
6875 lib/silcske/payload.[ch].
6877 * Added ^U functionality, clear input line. Patch from cras.
6879 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6881 * Mainly small bugfixes on core library. Fixed some debugging
6882 logging and buffer overflow in silclog.c.
6884 * Updated config.sub and config.guess on the distribution tree.
6886 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6888 * Added command lagging support in server. Client may execute
6889 commands now only once in two seconds.
6891 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6893 * Optimized packet reception. MAC computation and checking is now
6894 also more optimized. A lot previously duplicated code is now
6895 used as generic by both client and server.
6897 * Fixed key pair generation in clientutil.c
6899 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6901 * Added into lib/silccore/silcbufutil.[ch] new function;
6902 silc_buffer_realloc.
6904 * Moved generic packet sending/encryption functions to
6905 lib/silccore/silcpacket.[ch] from client and server. Some
6906 rewriting of the functions.
6908 * Moved all generic packet reception/decryption functions to
6909 lib/silccore/silcpacket.[ch] from client and server. The
6910 packet processing is now much cleaner in both client and server.
6911 These were major changes in both client and server.
6913 * Created many common functions in server to do packet sending.
6914 Previously code were duplicated a lot, this has been removed
6917 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6919 * Rewrote major parts of the ID cache system. Don't know
6920 whether it is better now or not but at least the API is more
6923 * Major rewrite on ID cache stuff on client because of the ID
6924 cache API changes. Added idlist.c to client.
6926 * Also major rewrite on ID cache stuff on server as well.
6927 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6928 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6929 in hand, instead they are all put into the ID cache system now.
6930 All server_idlist_* routines uses ID cache now instead of
6931 traversing its own lists (those lists does not exist anymore).
6932 SilcIDList though still exists. Also, SilcXXXEntry's are
6935 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6937 * Finally made the SKE implementation compliant to the protocol
6938 specification. All mp integers are now binary encoded as
6939 opposed being HEX encoded.
6941 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6944 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6945 functions: silc_[encode/decode]_pem. Also added function
6946 silc_encode_pem_file to PEM encode with newlines ('\n') for
6949 * SILC public keys are now encoded either PEM or binary. Same
6950 option is for private keys as well. By default private keys
6951 are binary encoded and public keys PEM encoded. Silly HEX
6952 encoding were removed.
6954 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6955 function to create fingerprints.
6957 * Fixed a bug in SHA1; does not change the original data anymore.
6959 * Partly implemented INFO command on client and server side.
6960 Fixed CLEAR command. Changes to SERVER command; show current
6961 server(s) when giving command without arguments. Added
6962 VERSION command to client.
6964 * Added check to server that unregistered connections cannot
6965 execute commands (unless it is specificly allowed).
6967 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6969 * Fixed screen refresh.
6971 * Fixed channel joining bug from client. On some circumstances
6972 client tried to join to a channel it had already joined.
6974 * Added public key verification process into client's protocol.c.
6975 The client now verifies the public key from user and saves
6976 it into ~./silc/serverkeys/ directory.
6978 Added into: clientutil.[ch]: silc_client_verify_server_key.
6980 * Changed SKE protocol's silc_ske_initiator_finish function
6981 to accept callback function that verifies the received public
6982 key. Removed old silc_ske_verify_public_key function.
6984 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6986 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6987 silc_pkcs_private_key[_data]_set.
6989 * Made the password and public authentication more cleaner in
6990 server's protocol.c.
6992 * Removed historic and obsolete protocol `channel_auth' from
6993 both client and server.
6995 * Removed wrong way of sending command status messages from
6996 server to client in server's command.c. The old way violated
6997 protocol specification.
6999 Changes to silccore/silccommand.[ch]: removed
7000 silc_command_encode_status_payload -> not needed anymore,
7001 changed silc_command_encode_payload_va to accept extra
7002 argument on variable argument list. The argument type must
7003 now be provided to the function. Also, added new function:
7004 silc_command_encode_reply_payload_va which is same as
7005 normal command_encode_payload_va except command status type
7006 is provided as extra argument.
7008 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
