37 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
39 * Fixed CUMODE_CHANGE notify handling to change the mode of
40 correct client. Affected file lib/silcclient/client_notify.c.
42 * Make silc_rng_alloc fail if it cannot allocate the sha1
43 hash algorithm. Affected file lib/silccrypt/silcrng.c.
45 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
47 * Fixed the file transfer's key agreement payload to include
48 zero port also if the hostname is NULL because it could not
51 Call file transfer monitor callback now also if error occurs
52 during key agreement protocol.
54 Changed the silc_client_file_send interface to return the
55 SilcClientFileError instead of session id. The session ID
56 is returned into pointer provided as argument.
58 Check that the file exists locally before sending the
59 file transfer request at all.
61 Affected file lib/silcclient/client_ftp.c, silcapi.h.
63 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
64 error than can occur while key agreement protocol. Affected
65 file lib/silcclient/silcapi.h.

68 is changed and +k mode is set in the channel. Affected file
69 irssi/src/silc/core/silc-channels.c.
71 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
72 SILC_LOG_WARNING to give out Warning and not Error. Affected
73 file lib/silcutil/silclog.c.
75 * Fixed the channel message payload decryption in the function
76 silc_channel_message_payload_decrypt to not modify the original
77 buffer before it is verified that the message decrypted
78 correctly. Otherwise, next time it is called with correct
79 channel key it won't encrypt since the payload is corrupted.
80 Affected file lib/silccore/silcchannel.c.
82 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
84 * Do not constantly resize the window. A fix patch by cras.
85 Affected file irssi/src/fe-text/screen.c.

94 * Fixed a bug in hash table internal routine for traversing
95 the table with foreach callback. The current entry may
96 become invalid in the callback but it was referenced after
97 the callback returned.
99 Do not allow auto rehashing of hash table during the
100 silc_hash_table_foreach operation, for same reasons as it is
101 not allowed for SilcHashTableList. Affected files are
102 lib/silcutil/silchashtable.[ch].
104 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
106 * Defined DLLAPI into silcincludes.h and silcwin32.h for
107 Win32 DLL. extern's in header files are now declared with
110 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
112 * Fixed private message handling. It used some old code that
113 caused the client to crash. Affecte file is
114 lib/silcclient/client_prvmsg.c.
116 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
118 * Added function silc_client_add_channel,
119 silc_client_replace_channel_id, and removed functions
120 silc_client_new_channel_id and silc_idlist_get_channel_by_id
123 * Added cross reference of the joined channels to the
124 SilcClientEntry, and changed the SilcChannelEntry's
125 users list to SilcHashTable. The affected files are
126 lib/silcclient/idlist.[ch].
128 * Fixed a bug in hash table tarversing. While the hash table
129 is traversed with SilcHashTableList the table must not be
130 rehashed. It is now guaranteed that auto rehashable tables
131 are not rehashed while tarversing the list. Also defined that
132 silc_hash_table_rehash must not be called while tarversing
133 the table. Added function silc_hash_table_list_reset that must
134 be called after the tarversing is over. The affected files are
135 lib/silcutil/silchashtable.[ch].
137 * Changed all hash table traversing to call the new
138 silc_hash_table_list_reset in server and in client library.
140 * Added function silc_client_on_channel to return the
141 SilcChannelUser entry if the specified client entry is joined
142 on the specified channel. This is exported to application as
143 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
145 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
147 * Fixed founder regaining problem with JOIN command on normal
148 server. The notify for mode change must be sent always and
149 not only if !cmd->pending. Affected file silcd/command.c.
151 * Fixed the WHOWAS command's reply sending to support the
152 lists correctly. Affected file silcd/command.c.
154 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
156 * When sending JOIN command to router for processing the
157 sender's old command identifier was not saved back to the
158 sender's command context, fixed now. The affected file is
161 * Create the key in JOIN command of the router did not return
162 the channel key, added check for this. Affected file is
165 * Fixed a channel ID update bug in JOIN command reply. Do
166 not directly upgrade the ID but call the function
167 silc_idlist_replace_channel_id if the ID was changed.
168 Affected file silcd/command_reply.c.
170 * Fixed memory leaks from command calling if it would fail.
171 Affected file silcd/command.c.
173 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
175 * Applied patches from cras:
177 Memory leak fixes around libaries, irssi window resize fix,
178 new silclist.h and silcdlist.h, all extern inline changed to
181 * Removed dotconf from lib/dotconf, not needed anymore.
183 * Removed TRQ from lib/trq, not needed anymore.
185 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
186 with server connections. Later this will be configurable
187 in config file after new config file is done. Affected file
190 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
192 * Fixed a crash in server related to channel announcements.
193 Affected file silcd/server.c.
195 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
197 * Fixed memory leaks in silc_server_create_new_channel*
198 functions. Affected file silcd/server.c.
200 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
201 which ID was changed. This way the router will send the
202 user list for the channel again, and server won't be in
203 desync in some rare circumstances. Affected file is
204 silcd/packet_receive.c.
206 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
208 * Check for NULL socket pointer in the function
209 silc_server_packet_send_to_channel_real. Affected file
212 * Fixed the BAN notify handling to correctly remove ban
213 list. Affected file silcd/packet_receive.c.
215 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
217 * Fixed some header addition to Toolkit distribution in
218 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
220 * Added lib/silcclient/client_ops_example.h as an template
221 file for application programmers to quickly start using
222 the SilcClientOperation functions in their application.
223 Updated the lib/silcclient/README as well to tell about this
224 nice file made available.
226 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
228 * Call silc_server_remove_from_channels when removing client
229 entry when NO_SUCH_CLIENT_ID was received. Affected file
230 is silcd/command_reply.c.
232 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
234 * Added server & router operator statistics updating. Affected
235 file silcd/packet_receive.c and silcd/command.c.
237 * Fixed the SERVER_SIGNOFF notify handling on normal server
238 not to save the history information for clients. Same was
239 fixed earlier in remove_clients_by_server function, but not
240 here. Affected file silcd/packet_receive.c.
242 * Raised the default connection-retry count from 4 to 7 in
243 server. Affected file silcd/server.h.
245 * Cancel any possible reconnect timeouts when we start the
246 key exchange. Affected file silcd/server.c.
248 * Do not reconnect on connection failure when SCONNECT was
249 given. Affected files silcd/server.[ch].
251 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
253 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
255 * Fixed the NICK command to always give the unformatted
256 nickname to the one giving the NICK command. If unformatted
257 nickname is cached already it will be formatted and the
258 local entry will always get the unformatted nickname.
259 Affected file lib/silcclient/idlist.c.
261 * Fixed some double frees from client library commands.
262 Affected file is lib/silcclient/command.c.
264 * Fixed CUMODE command in server to assure that no one can
265 change founder's mode than the founder itself, there was a
266 little bug. Affected file silcd/command.c.
268 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
270 * Removed the SilcClientCommandDestructor from the client
271 libary, it is not needed anymore. Affected files are
272 lib/silcclient/silcapi.h, command[_reply].[ch],
273 client_notify, idlist.c.
275 * Fixed GETKEY command to first resolve client, and then
276 resolve the server only if the client was not found, instead
277 of resolving both at the same time. Affected file is
278 lib/silcclient/command.c.
280 * Added silc_client_start_key_exchange_cb and lookup the
281 remote hostname and IP address before starting the key
282 exchange with server. The affected file is
283 lib/silcclient/client.c.
285 * The server's public key is now saved using the IP address
286 of the server and not the servername for the filename.
287 The hostname public key filename is checked as an fall back
288 method if the IP address based filename is not found.
290 Fixed the GETKEY command to save the fetched server key
293 Print the remote server's hostname now when new key is
294 received during connection process. Affected file is
295 irssi/src/silc/core/client_ops.c.
297 * Return always our own public key to the client if it asks
298 for it with GETKEY command. Affected file silcd/command.c.
300 * Removed the use_auto_addr variable from default config
301 file since it was in wrong section. Affected file is
304 * Fixed TOPIC_CHANGE notification to not route it when it
305 was sent using silc_server_send_notify_to_channel function.
306 Affected file silcd/command.c.
308 * Fixed silc_server_send_notify_kicked to send the kicker's
309 Client ID also, it was missing. Affected files are
310 silcd/command.c, silcd/packet_send.[ch].
312 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
314 * Do not save client history information in SERVER_SIGNOFF.
315 Fixes the bug in normal server that it does not detect
316 the client becoming valid after the server becomes back
317 online. Affected file silcd/server_util.c.
319 * Added `sock_error' field into the SilcSocketConnection
320 context. When error occurs during socket operation (read
321 or write) the error is saved. Added also new function
322 silc_socket_get_error to return human readable socket error
323 message. Affected files are lib/silcutil/silcsockconn.[ch],
324 lib/silcutil/unix/silcunixsockconn.c, and
325 lib/silcutil/win32/silcwin32sockconn.c.
327 * The server now prints the socket error message in the
328 signoff for client. Affected file silcd/server.c.
330 * Fixed the `created' channel information sending from router
331 to server in JOIN command. Checks now whether the channel
332 really was created or not and set it according that.
334 Fixed the JOIN command to use the client entry's current
335 ID during the joining procedure instead of the one it sent
336 in the command (it is checked though), since it can change
337 between the packet processing and command processing, and
338 would just case unnecessary pain in the client end. Affected
339 file silcd/command.c.
341 * Fixed a channel key payload sending to use correct channel
342 ID when the server was forced to change the channel's ID by
343 router. Router sent the key payload with the old Channel ID.
344 Affected file silcd/packet_receive.c.
346 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
348 * Call silc_server_save_channel_key only if the key payload
349 was provided in the JOIN command's command reply. Affected
350 file silcd/command_reply.c.
352 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
354 * Fixed silc_mp_sizeinbase to return the value correctly with
355 MPI. Affected file lib/silcmath/mp_mpi.c.
357 * Fixed the stop_server signal to correctly stop the scheduler
358 and gracefully stop the server when SIGTERM or SIGINT signals
359 are received. Affected file silcd/silcd.c.
361 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
363 * Simple handling of TERM and HUP signals. Also added some log
364 flushing call around. Affected file is
367 * Fixed small bugs in silclog.c. Now buffering output will take
368 effect after 10 seconds since startup: This will ensure that
369 no important startup messages are lost. Also output redirection
370 will preserve original format ([Date] [Type] message).
371 Affected file is lib/silcutil/silclog.c.
373 * Added two options to the config file, in the logging section:
374 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
375 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
377 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
379 * Do not print the warning about log files not being initialized
380 more than once to avoid excess logging. Affected file is
381 lib/silcutil/silclog.c.
383 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
384 the SIM copying in make install in Makefile.am.pre.
386 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
388 * Rewritten silclog APIs. Globally interesting changes follows:
389 silc_log_set_files() changed to silc_log_set_file().
390 silc_log_set_callbacks() changed to silc_log_set_callback().
391 ROBOdoc documented silclog header file.
392 SilcLogCb now returns bool to wether inihibit the default
393 handler or not (to keep the old behaviour return always TRUE).
394 The new APIs should also fix the problem of the
395 silcd_error.log file that was written in the current directory.
398 Log files streams will remain opened after silc_log_set_file()
399 call, means less CPU usage notably on high traffic servers.
400 File streams are now full buffered, and flushed to the disk
401 every 5 minutes, lesses HD activity and CPU usage.
402 Messages can be redirected, allowing admins to configure
403 one single logfile for all server messages.
404 the silc_log_quick global variable to activate fast-logging.
405 Affected files lib/silcutil/silclog.[ch]
407 * Changed some code to conform new silclog APIs. Affected
408 files are doc/example_silcd.conf.in, silcd/server.c
409 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
412 * Fixed a memory leak that could occur in some situations.
413 Affected file silcd/serverconfig.c.
415 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
417 * Added the silc_client_del_client to remove the client from
418 all channels as well. Affected file lib/silcclient/idlist.c.
420 * Fixed the client library to correctly remove the client
421 from all channels when the client entry is being destroyed.
422 Affected file lib/silcclient/client_notify.c, command.c.
424 * Added auto-nicking support to the client library. If the
425 applicatio now sets client->nickname it will be sent to the
426 server after connecting by the library. This way for example
427 SILCNICK (or IRCNICK) environment variables will have effect
428 and always change the nickname automatically to whatever
429 it is wanted. Affected file lib/silcclient/client.[ch].
431 * Renamed silc_server_command_bad_chars to the
432 silc_server_name_bad_chars and moved it to the
433 silcd/server_util.[ch]. Added also new function
434 silc_server_name_modify_bad to return nickname that
435 includes bad characters as new nickname without those
436 bad characters. This check and modify is now used in
437 silc_server_new_client when the username is initially set
438 as nickname, so it must be checked to be valid nickname.
439 Affected file silcd/packet_receive.c.
441 * The nickname length is now taken from the packet for real
442 and not trusted to strlen() since it clearly can return
443 wrong length for nickname including bad characters. This
444 also applies to channel names. Affected file silcd/command.c.
446 * Removed the lib/silcsilm/modules directory. Modules are now
447 compiled into the lib/silcsim. Fixed the copying of the
448 modules to follow symbolic links in Makefile.am.pre.
450 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
452 * Fixed silc_string_regexify list creation. Fixes bugs with
453 BAN and INVITE commands in server. The affected file is
454 lib/silcutil/unix/silcunixutil.c.
456 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
458 * Removed the command destructor entirely from the server's
459 command and command reply routines. It is not needed, and
460 its usage was buggy and caused crashes. Affected files are
461 silcd/command[_reply].[ch].
463 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
465 * Cancel protocol and NULL sock->protocol if timeout
466 occurred during protocol. Affected file silcd/server.c.
468 * Cancel protocol timeouts always before calling the final
469 callback, to assure that after final callback is called
470 no other state will be called for the protocol anymore.
471 Affected file silcd/protocol.c.
473 * Print error log if incoming connection configuration could
474 not be found. Affected file silcd/server.c.
476 * Fixed JOIN command to correctly save the founder mode
477 to the client on normal SILC server, when the channel
478 was created by the router. Affected file silcd/command.c.
480 * Fixed LIST command (hopefully) to send correct reply
481 packets. Affected file silcd/command.c.
483 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
485 * The silc_packet_receive_process now returns FALSE if the
486 read data was invalid packet, and TRUE if it was ok.
488 The server now checks that if unauthenticated connection
489 sends data and its processing fails the server will close
490 the connection since it could be a malicious flooder.
492 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
494 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
496 * Make sure the warning about error opening a log file is
497 printed only once and not everytime it fails (produces
498 too much useless log). Affected file lib/silcutil/silclog.c.
500 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
502 * Made the silc_server_daemonise() function more readable.
503 Affected file silcd/server.c.
505 * Pid file is now optional, the user may comment it out from
506 the config file. Removed define SILC_SERVER_PID_FILE, we
507 don't need a default any longer. Affected file
508 configure.in.pre, lib/Makefile.am.pre.
510 * Make some use of the pid file. The server now dies at startup
511 if it detects a valid pid file on his path. The server would
512 die anyway in this circumstance, because of the bind() failure.
513 Affected file silcd/silcd.c.
515 * No longer compiling lib/dotconf.
517 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
519 * Fixed JOIN command parsing not to crash. Affected file
520 lib/silcclient/command.c.
522 * Fied the NICK_CHANGE notify to add the new client entry
523 even it is resolved. This removes an <[unknown]> nick
524 thingy bug in the client. Affected file is
525 lib/silcclient/client_notify.c.
527 * Do not try to allocate 0 bytes (efence does not like it)
528 in lib/silccore/silccomand.c when encoding payload.
530 * Do not take IRCNICK as nickname in Irssi SILC client since
531 it is not possible to set nickname before hand connecting
532 the server (TODO has an entry about adding auto-nicking
535 * Changed the silc_server_command_pending to check whether
536 there already exists an pending entry with the specified
537 command, command identifier and pending callback. This is
538 to fix IDENTIFY and WHOIS related crashes that may register
539 multiple pending commands with same identifier. Affected
540 file silcd/command.c.
542 * Fixed the server to reconnect to the router even if it
543 was already reconnecting and EOF was received. This to
544 fix a possibility that the server wouldn't ever try to
545 auto-reconnect to the router. Affected file silcd/server.c.
547 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
549 * Fixed the server's password authentication to use the
550 length of the locally saved password, and not the one
551 sent in the packet. Affected file silcd/protocol.c.
553 * Fixed same password authentication problem in the
554 Authentication Payload handling routines in
555 lib/silccore/silcauth.c.
557 * Yet another password authentication problem fixed with
558 channel password handling in silcd/command.c.
560 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
562 * If first character of string in silc_parse_userfqdn is '@'
563 then do not parse it. Affected file is
564 lib/silcutil/silcutil.c.
566 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
568 * Fixed minor bug in IDENTIFY command reply sending, which
569 caused various weird problems during JOIN when it was
570 resolving names for users. Affected file silcd/command.c.
572 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
574 * Fixed the IDENTIFY command reply sending to chech better valid
575 clients. It was possible to send incomplete list of replies.
576 Affected file silcd/command.c.
578 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
580 * Added silc_client_command[s]_[un]register functions now to
581 dynamically register the commands in client library. Removed
582 the static table of commands. This allows the client library
583 to call commands without causing the application to know about
584 what commands library has called.
586 Removed the INFO command reply kludge to detect when the command
587 was called by library. Now library use its own command reply
588 function for INFO command.
590 Added function silc_client_command_call to call a command.
591 Application can use it to call command, not access the structure
594 Now all commands that are sent by the client library (not
595 explicitly sent by application) use own command reply functions.
597 Affected files around lib/silcclient/ and in
598 irssi/src/silc/core/.
600 * Fixed the WHOIS command reply sending to chech better valid
601 clients. It was possible to send incomplete list of replies.
603 Fixed the WHOIS and IDENTIFY to send the request to router
604 if normal server did not do it and did not find any results.
606 Affected file silcd/command.c.
608 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
610 * Moved the internal data from SilcClient context into its
611 own file, not accesible to application. Affected files
612 lib/silcclient/client.h and lib/silcclient/client_internal.h,
613 and other files in client library.
615 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
617 * Added doc/examples installation target in Makefile.am.pre.
620 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
622 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
623 commands the found client entry will be removed from the
624 cache, after notifying application about the error. Affected
625 file lib/silcclient/command_reply.c.
627 * Changed the /MSG to check for exact nickname user gave, and
628 not let `nick' match `nick@host' if it is only one found. Now,
629 user must type the exact nickname (like nick@host2) even if
630 there are no more than one same nicks found. This is to avoid
631 a possibility of sending nickname to wrong nickname since
632 `nick' could match `nick@host'. Affected file is
633 irssi/src/core/silc-servers.c.
635 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
637 * Do not print "you are now server operator" or similar when
638 giving /away command. Affected files are
639 irssi/src/silc/core/client_ops.c, silc-servers.h.
641 * Made the silc_server_command_pending_error_check to send
642 the same command reply payload it received back to the
643 original sender of the command. This way all arguments
644 that was received by the server will be received by the
645 client too. Affected file silcd/command.c.
647 * Added the silc_idcache_add to return the created cache entry
648 to a pointer. Affected file lib/silccore/silcidcache.[ch].
650 * Add global clients to expire if they are not on any channel.
651 This is because normal server will never know if they signoff
652 if they are not on any channel. The cache expiry will take
653 case of these entries. This is done by normal servers only.
654 The affected files are silcd/command_reply.c,
655 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
657 * If server receives invalid ID notification for WHOIS or
658 IDENTIFY and the ID exists in the lists, it is removed.
659 Affected file silcd/command_reply.c.
661 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
662 in client then client entry that it matches is searched and
663 the nickname is printed on the screen for user. Affected
664 file irssi/src/silc/core/client_ops.c.
666 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
668 * Use cache entry expire time in the LIST command reply to
669 purge old entries from the cache after the LIST command
670 reply has been received. This way we don't have non-existent
671 entries in the cache for too long. Affected file is
672 silcd/command_reply.c.
674 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
676 * If we are normal server, and we've not resolved client info
677 in WHOIS or IDENTIFY from router, and it is global client,
678 we'll check whether it is on some channel. If it is not
679 then we cannot be sure about its validity and will resolve it
680 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
681 file silcd/command.c.
683 * Search channel by name (if possible) rather than by ID
684 in IDENTIFY command's command reply. Affected file is
685 silcd/command_reply.c.
687 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
689 * Distribute to the channel passphrase in CMODE_CHANGE notify.
690 Updated specs and implemented it. Affected file silcd/command.c,
691 silcd/packet_send.c and silcd/packet_receive.c.
693 * Implemented the <founder auth> payload handling in the JOIN
694 command. If provided all conditions for channel joining
695 except requirement to provide correct passphrase can be
696 overrided by the channel founder. Updated the protocol specs.
697 Affected file silcd/command.c.
699 Added support for founder auth in JOIN command in client
700 library. Fixed the parsing of the JOIN command now to support
701 all options as they should be. The affected file is
702 lib/silcclient/command.c.
704 * Optimized the WHOIS and IDENTIFY commands to send the request
705 to router only if it includes nicknames or other names. If
706 they include only IDs then check the local cache first before
707 routing. Affected file is silcd/command.c.
709 * Added channels topic announcements. Affected file is
710 silcd/packet_receive.c and silcd/server.c.
712 * Fixed the silc_server_send_notify_topic_set to really destine
713 the packet to channel. Affected file silcd/packet_send.c.
715 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
716 library. Affected file lib/silcclient/client_notify.c.
718 * Added UMODE announcements. Affected file silcd/server.c.
720 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
722 * Memory leak fixes in:
724 lib/silcutil/silcsockconn.c
725 lib/silcske/silcske.c
728 lib/silccrypt/silcpkcs.c
729 lib/silccore/silccommand.c
730 lib/silccore/silcidcache.c
735 * ROBOdoc documented the lib/silcske/groups.h file and a
736 bit changed the interface for better.
738 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
740 * Update the client entry context in the ID cache after
741 nick change. Affected file lib/silcclient/command.c.
742 Fixes the CUMODE command when regaining founder privileges,
743 and a little WHOIS problem.
745 * Fixed silc_net_gethostbyname to correctly call the
746 inet_ntop. Affected file lib/silcutil/silcnet.c.
748 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
750 * Added IPv6 support checking to the configure.in.pre, added
751 also --enable-ipv6 option to override the check. Affected
752 file configure.in.pre.
754 * The silc_thread_create now calls the start function
755 directly if threads support is not compiled in. Removes
756 ugly #ifdef's from generic code. Affected files are
757 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
759 * Added silc_net_gethostby[name/addr]_async to asynchronously
760 resolve. Affected files are lib/silcutil/silcnet.[ch].
762 * Added support for rendering IPv6 based server, client and
763 channel IDs. Affected file lib/silcutil/silcutil.c.
765 * Added support for creating IPv6 based server IDs. Affected
766 file is silcd/serverid.c.
768 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
770 * Added silc_net_gethostby[addr/name] into the
771 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
772 routines. Added silc_net_is_ip[4/6]. Affected file is
773 lib/silcutil/unix/silcunixnet.c. All routines that take
774 address as argument now supports both IPv4 and IPv6 addresses.
776 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
778 * Fixed LIST command reply sending in server. Affected file
781 * Server now sends the kicker's client ID in the KICK notify
782 to the kicked client. Affected file silcd/command.c.
784 * The client library now parses the kickers client ID and
785 UI displays it. Affected files lib/silcclient/client_notify.c
786 and irssi/src/silc/core/silc-channels.c, module-formats.c.
788 * Made all payload parsing function prototypes consistent.
789 They all take now const unsigned char * and uint32 pair as
790 the payload data instead of SilcBuffer. Changes all around
791 the source tree. Other unsigned char* -> const unsigned char*
792 changes around the tree as well.
794 * Optimized SFTP client and server packet sending not to
795 allocate new buffer for each packet but to recycle the
796 first allocated buffer. Affected files are
797 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
799 * Optimized the SFTP client to use SilcList instead of
800 SilcDList for requests, because it is faster. Affected file
801 is lib/silcsftp/sftp_client.c.
803 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
804 into lib/silccore/silcid.[ch].
806 Renamed silcpayload.[ch] into silcargument.[ch].
808 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
810 * If client entry is deleted with active key agreement
811 session, abort the session.
813 The silc_client_abort_key_agreement now calls the completion
814 callback with new SILC_KEY_AGREEMENT_ABORTED status.
816 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
819 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
821 * Don't use __restrict in older GCC's. Affected file is
822 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
824 * silc_net_localhost now attempts to reverse lookup the
825 IP/hostname. Affected file lib/silcutil/silcnet.c.
827 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
828 command. It can be used to gain founder privileges at
829 the same time when joining the channel.
831 Defined that the SILC_NOTIFY_TYPE_KICKED send the
832 kicker's client ID as well. Updated protocol specs.
834 Defined that the server must send SILC_COMMAND_IDENTIFY
835 command reply with error status to client who sent
836 private message with invalid client ID.
838 Updated the protocol specification.
840 * Added silc_server_send_command_reply to send any
841 command reply. Affected file silcd/packet_send.[ch].
843 * Added silc_id_payload_encode_data to encode ID payload
844 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
846 * The server now send IDENTIFY command reply with error
847 status if client ID in private message is invalid. Affected
848 file silcd/packet_receive.c.
850 * Save the server key file with server's IP address in
851 the filename instead of hostname. The affected file is
852 irssi/src/silc/core/client_ops.c.
854 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
856 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
859 * Added libtool support for compiling shared objects in
860 lib/silcsim. Affected file configure.in.pre and
861 lib/silcsim/Makefile.am. Original patch by cras.
863 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
865 * Pid file configuration, and server's config file fixes
866 patch by toma. Updated CREDITS file.
868 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
870 * Fixed silc_client_channel_message to not try to decrypt
871 the message twice if it resolved the destination client
872 information. This could cause of dropping one channel
873 message. Affected file lib/silcclient/client_channel.c.
875 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
877 * Added silc_client_run_one into lib/silcclient/silcapi.h and
878 lib/silcclient/client.c. This function is used when the SILC
879 Client is run under some other scheduler, or event loop or
880 main loop. On GUI applications, for example this may be
881 desired to used to run the client under the GUI application's
882 main loop. Typically the GUI application would register an
883 idle task that calls this function multiple times in a second
884 to quickly process the SILC specific data.
886 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
888 * Fixed silc_server_drop() for dropping the supplementary
889 groups as well, this could cause a security hole on some
892 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
894 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
897 * Write PID file after dropping privileges. Added -F option
898 to run server on foreground. A patch by debolaz.
899 Affected files silcd/server.c, silcd/silcd.c.
901 * Fixed MOTD to return the MOTD file server name. Affected
902 file silcd/command.c.
904 * Added INFO command reply handling to the Irssi SILC Client.
905 Affected file irssi/src/silc/core/client_ops.c.
907 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
909 * Fixed the silc_idcache_list_* routines to really support
910 the dynamic list. Fixes a crash. Affected file is
911 lib/silccore/silcidcache.c.
913 * Fixed the LIST command reply to really call LIST command's
914 pending callbacks. Affected file silcd/command_reply.c.
916 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
918 * Update conn->local_entry->nickname after giving NICK
919 command. Affected file lib/silcclient/command.c.
921 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
923 * Added the [pid] option to the silcd configuration file
925 Affected files: serverconfig.[ch] and silcd.c
927 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
929 * Save fingerprint in WHOIS command reply in server.
930 Affected file silcd/command_reply.c.
932 * Fixed NICK commands pending callback registration.
933 Affected file lib/silcclient/command.c.
935 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
937 * Use ++server->cmd_ident when sending commands in server,
938 instead of random number. Affected file silcd/command.c.
940 * Fixed GETKEY command reply to call actually GETKEY pending
941 command callbacks. Affected file silcd/command_reply.c.
943 * A bit stricter check for nicknames. Check for same nickname
944 in NICK command also. Affected file silcd/command.c.
946 * Do not call INFO command everytime client ID changes, only
947 during first connecting. Affected file lib/silcclient/client.c.
949 * Set the new nickname only after successful command reply for
950 NICK command is returned by server. Affected file
951 lib/silcclient/command.c.
953 * Remove nicknames from nicklist during server_signoff notify.
954 Should fix /NAMES bit more. The affected file is
955 irssi/src/silc/core/silc-channels.c.
957 * Added `fingerprint' field to the SilcIDListData in the
958 silcd/idlist.h to hold the fingerprint of the client's
961 Send the fingerprint of the client's public key in WHOIS
964 Affected files silcd/command.c, and silcd/idlist.[ch].
966 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
967 create fingerprint from given data.
969 * Show the fingerprint of the client's public key in WHOIS.
970 Affected files irssi/src/module-formats.[ch] and
971 irssi/src/silc/core/client_ops.c.
973 * Format the multiple same nicknames also during JOIN and
974 NICK_CHANGE notifys. Affected file is
975 lib/silcclient/client_notify.c.
977 * Do not print error on screen for invalid private message
978 payload since it can come if someone is sending private
979 messages with wrong key. Affected file
980 lib/silccore/silcprivate.c.
982 * Fixed multiple concurrent /PING crash. Affected file
983 lib/silcclient/command.c.
985 * Changed the wrong ID encoding. All IP addresses must be
986 in MSB first order in encoded format. They were encoded
987 wrong and was in LSB format. Affected files are
988 silcd/serverid.c, lib/silcutil/silcutil.c.
990 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
992 * Call the `connect' client operation through the scheduler
993 in case of error. Affected file lib/silcclient/client.c.
995 * Call the `failure' client operation even if the error
996 occurred locally during a protocol. Affected file is
997 lib/silcclient/protocol.c.
999 * Added support of sending LIST command to router from normal
1000 server. This way normal server can get list of all channels
1001 in the network too. Fixed the channel list sending in the
1002 server too. Affected files are silcd/command.c, and
1003 silcd/command_reply.[ch].
1005 * Added silc_server_update_channels_by_server and
1006 silc_server_remove_channels_by_server. They are used during
1007 disconnection of primary router and in backup router protocol.
1008 Affected file silcd/server_util.[ch], silcd/server.c and
1009 silcd/server_backup.c.
1011 * Fixed channel adding to global list in IDENTIFY command
1012 reply in server. Affected file silcd/command_reply.c.
1014 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1016 * If the incoming packet type is REKEY or REKEY_DONE process
1017 that packet always synchronously. Fixes yet another MAC
1018 failed error on slow (dialup) connections. Affected file
1019 lib/silcclient/client.c and silcd/server.c.
1021 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1023 * Call check_version SKE callback for initiator too. Affected
1024 file lib/silcske/silcske.c.
1026 * Implemented fix for security hole found in the SKE that was
1027 fixed in the specification few days back; the initiator's
1028 public key is now added to the HASH value computation.
1029 Added backwards support for the old way of doing it too, for
1030 old clients and old servers. Affected file is
1031 lib/silcske/silcske.c.
1033 * Enabled mutual authentication by default in SKE. If initiator
1034 is not providing mutual authentication the responder will
1035 force it. This will provide the proof of posession of the
1036 private key for responder. The affected files are
1037 lib/silcclient/protocol.c and silcd/protocol.c.
1039 * Do not cache anymore the server's public key during SKE.
1040 We do mutual authentication so the proof of posession of
1041 private key is done, and if the server is authenticated in
1042 conn auth protocol with public key we must have the public
1043 key already. Affected file silcd/protocol.c.
1045 * Added new global debug variable: silc_debug_hexdump. If
1046 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1047 file lib/silcutil/silclog.[ch].
1049 * Fixed compilation warning due to char * -> const char *.
1050 Affected files lib/silcutil/silcnet.h, and
1051 lib/silccore/silcauth.[ch].
1053 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1055 * Fixed CMODE command when new channel key was created. If
1056 the creation failed the old key was removed. Next time giving
1057 same command would crash the server since the old key was
1058 freed already. Affected file silcd/command.c.
1060 * Fixed the silc_server_announce_get_channels to not crash
1061 on reconnect. Affected file silcd/server.c.
1063 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1065 * Added silc_log_set_debug_string function to set a regex
1066 string to match for debug output. Only the function names,
1067 or filenames matching the given debug string is actually
1068 printed. This way it is possible to filter out those debug
1069 strings that user is not interested in.
1071 Fixed a bug in silc_string_regexify.
1073 Affected files lib/silcutil/silclog.[ch], and
1074 lib/silcutil/unix/silcunixutil.c.
1076 * Changed the -d options in both server and Irssi SILC client
1077 to take the debug string as argument. Affected files
1078 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1080 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1082 * Added silc_hash_babbleprint to create a Bubble Babble
1083 Encoded fingerprint. The encoding is developed by Antti
1084 Huima (draft-huima-babble-01.txt), and it creates human
1085 readable strings out of binary data. Affected file
1086 lib/silccrypt/silchash.[ch].
1088 * Print the babble print now in addition of fingerprint as well
1089 in Irssi SILC client. Affected files are
1090 irssi/src/fe-common/silc/module-formats.[ch],
1091 irssi/src/fe-common/silc/core/client_ops.c.
1093 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1095 * Fixed a security problem found in SKE. The initiator's
1096 public key too is now added to the HASH hash value creation
1097 which is signed by the responder to create the SIGN value.
1098 This will prevent anyone in the middle to lie to the responder
1099 about the initiator's public key. If this is done now, the
1100 man in the middle will get caught. Updated the protocol
1103 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1105 * Better installation directory handling. Configure module
1106 paths and other paths automatically to example_silc* files
1107 in doc/. A patch by toma.
1109 * Fixed compiler warning from MPI library, and from SILC RNG.
1112 * Added SILC_SERVER_PID_FILE to define the pid file for server.

1137 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1139 * Added silc_pkcs_public_key_compare to compare two
1140 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1142 * Check that the client who set the founder mode on the
1143 channel is the same client that is giving the founder
1144 mode to itself. It is done by comparing the saved public
1145 key (it is saved even in the authentication is passphrase).

1153 * Process the DISCONNECT packet through scheduler in the
1154 client library. Affected file lib/silcclient/client.c.
1156 * Fixed the silc_client_packet_parse to not to increase
1157 the packet sequence number if the conn->sock and the
1158 current socket connection is not same. This can happen
1159 for example during key agreement when the conn includes
1160 multiple socket connections (listeners). Affected file
1161 lib/silcclient/client.c.
1163 * The sender of the file transfer request now provides also
1164 the pointer (listener) for the key exchange protocol. If
1165 the listener cannot be created then it sends empty key
1166 agreement and lets the receiver provide the listener.
1168 Added `local_ip' and `local_port' arguments to the
1169 silc_client_file_send. If they are provided they are used,
1170 if not then it will attempt to find local IP address, if
1171 not found or bind fails then the remote client will provide
1174 Affected files are lib/silcclient/client_ftp.c and
1175 lib/silcclient/silcapi.h.

1184 of the client's public key (if the proof of posession of the
1185 corresponding private key is verified by the server).
1186 Updated to the protocol specification.
1188 * Added support of receiving the client's public key's
1189 fingerprint in command reply in client library. Affected
1190 file is lib/silcclient/command_reply.c, and
1191 lib/silcclient/idlist.[ch].
1193 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1250 preserve the WHOWAS info for the client. Affected file
1251 silcd/server_util.c.
1253 * Fixed SERVER_SIGNOFF notify handling in the server. The
1254 server is now able to process incoming SERVER_SIGNOFF notify
1255 for a server that it doesn't even know about. It will remove
1256 the clients provided in the notify. Affected file
1257 silcd/packet_receive.c.
1259 * Check for partial packet in data queue after every packet that
1260 was found from the queue. Return and wait for more data if
1261 there is partial data in queue. Affected file is
1262 lib/silccore/silcpacket.c.
1264 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1279 irssi/src/fe-common/silc/module-formats.[ch].
1281 * Wrote a help file for FILE command.
1283 * Added silc_rng_global_get_byte_fast to get not-so-secure
1284 random data as fast as possible. Random data is read from
1285 /dev/urandom if available and from the SILC RNG if not
1286 available. It is used in padding generation. Affected file
1287 lib/silccrypt/silcrng.[ch].
1289 * All packets in client library are now processed synchronously.
1290 Optimized packet processing a lot. Affected file
1291 lib/silcclient/client.c.
1293 * All server connection packets are processing synchronously
1294 now in server, to optimize packet processing. Affected file
1297 * Include files are installed now only in Toolkit distribution
1298 if make install is given. Affected files: all Makefile.am's.

1302 * Assure that silc_client_notify_by_server_resolve does not
1303 resolve the client information multiple times. If it cannot
1304 be found by the first it cannot be found at all. Affected
1305 file lib/silcclient/client_notify.c.
1307 * Fixed WHOWAS command reply calling. Affected file
1308 lib/silcclient/command_reply.c.
1310 * Removed all references to silc_idlist_get_client from the
1311 Irssi SILC client since that call is internal call used by
1312 the library. The Irssi SILC client will use now client
1313 retrieval functions found in silcapi.h.
1315 * Fixed a bug in resolving nickname info before sending
1316 private message. It used freed memory. Affected file
1317 irssi/src/silc/core/silc-servers.c.

1338 * Added silc_net_localip to return local host's IP address.
1339 Affected file lib/silcutil/silcnet.[ch].
1341 * If key exchange or rekey protocol is active for a connection
1342 parse all packets syncronously since there might be packets
1343 in packet queue that we are not able to process without first
1344 processing packets before them. Affected file silcd/server,
1345 lib/silcclient/client.c.
1347 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1348 whether library should continue processing the packet.
1349 Affected file lib/silccore/silcpacket.h.

1399 Make sure also that USERS command reply does not resolve
1400 twice information. Affected file is
1401 lib/silcclient/command_reply.c.
1403 Make sure that silc_client_get_clients_by_list does not
1404 resolve twice same information.
1406 * Check for valid client->id in the silc_server_free_client_data.
1407 Affected file silcd/server.c.
1409 * Fixed /GETKEY nick@server not to crash if the server entry

1422 * Call the silc_server_udpate_servers_by_server in the
1423 primary router that comes back online in the backup resuming
1424 protocol. Otherwise it routes packets wrong. Affected file
1425 silcd/server_util.[ch], silcd/server_backup.c.
1427 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1429 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1430 lib/silcutil/silcbuffmt.[ch].
1432 * Redefined the SILC packet header to include the padding
1433 length. Affected file lib/silccore/silcpacket.[ch].
1435 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1436 length for maximum padding up to 128 bytes). Affected
1437 file lib/silccore/silcpacket.h.
1439 * Removed all backwards support for old 0.5.x MAC thingies.
1440 The SILC packet header change makes it impossible to be
1441 backwards compatible.
1443 * Send the ENDING packet with timeout in the backup resuming
1444 protocol. This is to assure that all routers has connected
1445 to the primary router. Affected file silcd/server_backup.c.
1447 * Changed the RNG to take the first IV from random data. It
1448 used to take it from zero actually. Changed the RNG also
1449 to use /dev/urandom during session. /dev/random is used
1450 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1452 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1455 (the packet length) encrypted. Affected files aroung the
1456 code tree, lib/silccore/silcpacket.[ch]. Removed the
1457 SilcPacketCheckDecrypt callback. It is not needed anymore
1458 since the silc_packet_receive_process will determine now
1459 whether the packet is normal or special.
1461 * Implemented the unidirectional MAC keys. Affected files
1462 lib/silcske/silcske.c, silcd/protocol.c and

1470 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1472 * Allow backup router to announce servers. All servers
1473 announced by backup router are added to the global list
1474 automatically. Update hte server's socket to our primary
1475 router also when backup router announces a server.
1476 Affected file silcd/packet_receive.c.
1478 * Do not update the client->router in the function
1479 silc_server_udpate_clients_by_server if the client is on
1480 global list. We might fail to find any specific server
1481 for locally connected clients and local cell clients. They
1482 should still use the `from' and not `to' as client->router.
1483 This fixes backup router resuming protocol. Affected file
1484 silcd/server_util.c.
1486 * Decrease channel statistics count only if the channel
1487 deletion worked. Affected files are silcd/server.c and
1488 silcd/server_util.c.
1490 * Added silc_server_update_servers_by_server to update origin
1491 of all server entries. Used during backup router protocol.

1508 to the router it came from. Affected file is
1509 silcd/packet_send.c. Fixed memory leak too.
1511 * Announce informations for incoming router connection, but
1512 only after checking if it is replaced by backup router.
1513 Affected file silcd/packet_receive.c.
1515 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1518 router environment. Affected file silcd/server_backup.c.
1520 * Route packet only to one router in the function
1521 silc_server_packet_send_to_channel. Affected file is
1522 silcd/packet_send.c.
1524 * Fixed silc_server_send_notify_dest to set the broadcast
1525 flag. Fixed the silc_server_send_notify_topic to actually
1526 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1527 Affected file silcd/packet_send.c.
1529 * Changed the SFTP Filesystem interface. Changed the
1530 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1531 the filesystem operation function. The SilcSFTPFilesystem
1532 is now a context that is allocated by all filesystem allocation
1533 functions and it already includes the operations structure
1534 and filesystem specific context. It is given as argument
1535 now to the silc_sftp_server_start. This made the interface
1536 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1537 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1539 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1541 * Changed the backup router adding and getting interfaces
1542 in the server. The router that will be replaced by the
1543 specified backup router is now sent as argument. Affected

1596 send any data. Affected file lib/silcclient/client.c.
1598 * Implemented the backup router support when the primary router
1599 goes down. The servers and routers can now use the backup
1600 router as new primary router without loosing connectivity.
1602 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1604 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1605 in the server to indicate disabled entry. All data read
1606 from the connection will be ignored and no data is sent
1607 for entry that is disabled. Affected files are
1608 silcd/idlist.h, silcd/server.c.

1633 take variable argument list pointer as argument. Affected
1634 file lib/silcutil/silcbuffmt.[ch].
1636 * Added silc_buffer_set function that is used to set data
1637 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1638 Affected file lib/silcutil/silcbuffer.h.
1640 * Changed various routines in the core library to use the new
1641 silc_buffer_set instead of allocating new buffer only for
1644 * Added 64-bit value formatting and unformatting support to the
1645 silc_buffer_[un]format routines. Affected file is
1646 lib/silcutil/silcbuffmt.[ch].
1648 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1649 to includes/bitmove.h.
1651 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1653 * Fixed channel user mode saving in client library. Affected
1654 file lib/silcclient/command[_reply].c.
1656 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1658 * Defined the file transfer to the SILC Protocol. Added
1659 new packet type SILC_PACKET_FTP and defined File Transfer
1660 Payload. The mandatory file transfer protocol is SFTP
1661 (SSH File Transfer Protocol). Affected file in addition
1662 of the internet draft is lib/silccore/silcpacket.h.
1664 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1665 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1666 is used as part of backup router protocol when the primary
1667 router of the cell is back online and wishes to resume
1668 the position as primary router.
1670 * Redefined the MAC generation keys in the protocol. The
1671 same key is not used anymore in both direction. Both
1672 direction will now use different keys for sending and
1673 receiving. This fixes a potential security flaw. This
1674 change causes incompatibilities in the protocol.
1676 * Redefined also the MAC computation from the packet.
1677 An packet sequence number is now added to the MAC
1678 computation. This prevents possible replay attacks against
1679 the protocol. This change too causes incompatibilities
1682 Added `sequence' field to the SilcPacketContext to hold
1683 the current sequence number for the packet.
1685 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1687 * Added `created' field to the SilcIDListData in the file
1688 silcd/idlist.h to indicate the time when the entry was
1691 * Added `created' field to the SilcChannelEntry too. Affected
1692 file silcd/idlist.h.
1694 * Added `creation_time' aguments to all the announcement functions
1695 in the server. If it is provided then only the entries that
1696 was created after the provided time frame are actually
1697 announced. Affected file silcd/server.[ch].
1699 * The protocol says that the Channel ID's IP address must be
1700 based on the router's IP address. Added check for this in
1701 the silc_server_new_channel when processing incoming New Channel
1702 Payload. Affected file silcd/packet_receive.c.
1704 * Print out the correct version with --version in SILC client.
1705 Affected file irssi/src/silc/core/silc-core.c.
1707 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1709 * Fixed WHOWAS command to check for completnes of the client
1710 entry always, not just when the command is coming from client.
1711 Affected file silcd/command.c.
1713 * Added new function silc_server_packet_queue_purge to purge the
1714 outgoing data queue to the network. After the function returns
1715 it is guaranteed that the outgoing packet queue is empty.
1716 Affected file silcd/packet_send.[ch].
1718 * Purge the outgoing packet queue in the rekey protocol's final
1719 callback to assure that all rekey packets go to the network
1720 before quitting the protocol. Affected file silcd/server.c.
1722 * Added silc_client_packet_queue_parse as similar function as
1723 in server to the client library. The affected file is
1724 lib/silcclient/client.c.
1726 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1728 * Splitted silcd/server.c and created silcd/server_util.[ch]
1729 for utility functions.
1731 * Added new socket flag SILC_SF_DISABLED to indicate that the
1732 connection is open but nothing can be sent to or received from
1733 the connection. Affected file lib/silcutil/silsockconn.[ch].
1734 The checking for disabled socket is checked in the low level
1735 silc_socket_write and silc_socket_read functions.
1737 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1739 * Allow only nicknames and channel names that fits into the
1740 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1742 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1744 * When processing JOIN command reply in server check that if
1745 the channel exists in our global list we'll move it the local
1746 list. Affected file silcd/command_reply.c.
1748 * Fixed the check whether client is joined on the channel already
1749 in JOIN command. Affected file lib/silcclient/command.c.
1751 * Fixed the JOIN command reply to check whether the channel
1752 already exists. Affected file lib/silcclient/command_reply.c.
1754 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1756 * Added silc_ske_status_string to map the SKE error numbers
1757 to readable strings. The affected files are
1758 lib/silcske/silcske[_status].[ch].
1760 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1762 * Do not show the private channels on the WHOIS channel list
1763 as it is not allowed by the protocol. The affected file is
1766 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1768 * Assure that the packet length digged from the actual packet
1769 is something sensible in the silc_packet_decrypt_rest_special
1770 in lib/silccrypt/silcpacket.c.
1772 * Free and NULL the allocated pointer in silc_hmac_alloc if
1773 the HMAC allocation fails. The affected file is
1774 lib/silccrypt/silchmac.c.
1776 * Print the selected security properties to the log files in
1777 the server. Affected file silcd/protocol.c.
1779 * Add SKE's reference counter even if calling the completion
1780 callback manually. Otherwise it goes negative, although it
1781 does not cause any problems. The affected file is
1782 lib/silcske/silcske.c.
1784 * Remove the client entry with short timeout after giving the
1785 KILL command. Affected file lib/silcclient/command.c.
1787 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1788 case all found clients are already disconnected (WHOWAS would
1789 found them) in the server. Affected file silcd/command.c.
1791 * Update the last_receive (time of last data received) to be
1792 updated only when received private or channel message so that
1793 the idle time showed in WHOIS makes more sense.
1795 * Added boolean field `valid' in to the SilcClientEntry in the
1796 client library to indicate whether the entry is valid or not.
1797 This fixes the nickname change bug on channel when changing
1798 the nickname to be same than the old (like nick to Nick) the
1799 nickname formatter doesn't set the new nick anymore to Nick@host.
1800 Affected file lib/silcclient/idlist.[ch].
1802 * Now actually fixed the nickname changing on disconnection.
1803 Added new function silc_change_nick to the Irssi SILC Client.
1804 Affected file irssi/src/silc/core/client_ops.c,
1805 irssi/src/silc/core/silc-nicklist.[ch].
1807 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1809 * Check that the public key exists in the GETKEY command before
1810 trying to encode it. Affected file silcd/command.c.
1812 * Print some notifications on received public keys with GETKEY
1813 command in the Irssi SILC Client. Affected files are
1814 irssi/src/fe-common/silc/module-formats.[ch],
1815 irssi/src/silc/core/client_ops.c.
1817 * Use IDENTIFY command to resolve the server information in the
1818 GETKEY command instead of INFO command. Affected file
1819 lib/silcclient/command.c.
1821 * All command reply functions in the client library now calls
1822 the pending command reply callbacks even if an error has
1823 occurred. The server has done this a long time and now it was
1824 time to move the client library to this as well. Now all
1825 errors can be delivered back to the pending command reply
1826 callbacks if necessary. Affected files are
1827 lib/silcclient/command[_reply].[ch].
1829 * Change the nickname on disconnection back to the username
1830 because in reconnect the server will enforce it to it anyway.
1831 Affected file irssi/src/silc/core/silc-servers.c.
1833 * Fixed a config file parsing bug in the Irssi SILC client.
1834 Affected file irssi/src/silc/core/clientconfig.c.
1836 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1838 * When printing the channel mode on JOIN, verify that the
1839 channel key and channel's HMAC are valid. Affected file
1840 irssi/src/silc/core/client_ops.c.
1842 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1844 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1845 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1846 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1848 * Removed channel key rekey task deleting from the function
1849 silc_server_save_channel_key. Affected file silcd/server.c.
1850 Added explicit timeout task context instead that is used to
1851 delete the task if we are registering a new task before the
1852 new task has elapsed.
1854 * When channel key rekey occurs the client library now saves
1855 the old channel key for a short period of time (10 seconds) and
1856 is able to use it in case some is still sending channel
1857 messages encrypted with the old key after the rekey. Affected
1858 file lib/silcclient/[idlist.h|client_channel.c].
1860 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1862 * Added check to the silc_server_new_id_real to not accept
1863 new ID if it is the sender's own ID. Affected file is
1864 silcd/packet_receive.c.
1866 * Assure that we do not announce ourself or the one we've
1867 sending our announcements when we're router and are announcing
1868 servers to our primary router. Affected file silcd/server.c.
1870 * Fixed silc_server_command_identify_check_client to assemble
1871 correct WHOIS packet. It send corrupted WHOIS packet and
1872 caused problem with router to router connections. Affected
1873 file silcd/command.c.
1875 Fixed also silc_server_command_whois_check the same way
1876 as for the IDENTIFY command.
1878 * Added new SilcIDListStatus to the server in the SilcIDListData
1879 structure. The status now includes the current status of
1880 the entry (like registered, resolved etc.). Affected file
1881 silcd/idlist.[ch]. Defined a bunch of different status types
1882 as well. This replaced the old boolean registered field as well.
1884 Added resolve_cmd_ident field to the SilcClientEntry structure
1885 too so that if the entry is for example being resolved so
1886 another command may attach to the same pending command reply
1887 without requiring to resolve the same entry again. This concept
1888 should optimize the WHOIS and the IDENTIFY resolving under
1889 heavy load by taking away unnecessary resolving for entries
1890 that are being resolved already.
1892 Added support for adding multiple pending commands for one
1893 command idenfier. Affected file silcd/command[_reply].[ch].
1895 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1896 before deleting the data. Otherwise the hash table will have
1897 freed data in comparison functions. Affected file is
1898 silcd/command_reply.c.
1900 * Fixed silc_idlist_replace_client_id to add the new entry to
1901 the cache with NULL nickname. Otherwise there will be invalid
1902 memory as the nickname after the nickname is freed. Affected
1903 file silcd/packet_receive.c.
1905 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1906 saved into wrong slots because the previous number of entries
1907 was not taken into account. Affected file silcd/idlist.c.
1908 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1910 * If we are router and we receive JOIN notify to a channel that
1911 does not have any users then notified client is marked as the
1912 channel founder, as it is it. The affected file is
1913 silcd/packet_receive.c
1915 * Added to the extended hash table API's table_del_*ext functions
1916 the destructor as argument too, so that the caller can decide
1917 which destructor to use or whether to use destructor at all.
1918 Affected file lib/silcutil/silchashtable.[ch].
1920 * Fixed ID Cache purging. It actually deleted the entries from
1921 the hash table after the data was freed. The hash table ended
1922 up comparing freed memory. The affected file is
1923 lib/silccore/silcidcache.c.
1925 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1927 * Fixed Irssi SILC client's KILL command's HELP syntax.
1929 * The USERS command now resolves the detailed user information
1930 if the userinfo field is missing. Affected file is
1931 lib/silcclient/command_reply.c.
1933 * Do not print error in silc_file_read if the read file does
1934 not exist. Just silently return NULL. Affected file is
1935 lib/silcutil/silcutil.c.
1937 * Fixed the silc_log_output to not wine about NULL filename
1938 and to not create some bogus " " filename. Affected file is
1939 lib/silcutil/silclog.c.
1941 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1943 * Fixed various printing bugs on the user interface in the
1944 Irssi SILC Client. Minor changes that were forgotten from
1947 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1949 * Fixed the configure.in.pre and the compilation and distribution
1950 environment to support the new autoconf 2.52. That version is
1951 now required to compile the CVS trunk.
1953 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1955 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1956 to generally parse user@fqdn format strings. Affected file
1957 lib/silcutil/silcutil.c.
1959 * Added nickname_format and nickname_force_format fields to the
1960 SilcClientParams structure. The first one defines the format
1961 for the nicknames that the library will enforce if the receives
1962 multiple same nicknames. The second one is boolean value and
1963 can be used to force the library to always enforce the format
1964 to the nicknames regardles whether there are multiple nicknames
1965 or not. This configurable formatting was employed to flexibly
1966 support accessing multiple nicknames from the user interface.
1967 The userinterface can now set the nicknames to what ever format
1968 they prefer. Affected file lib/silcclient/silcapi.h.
1970 Added function silc_client_nickname_format to the file
1971 lib/silcclient/idlist.c. It performs the nickname formatting.
1973 Added new field `hostname´ to the SilcClientEntry context.
1974 It holds the hostname of the client. Affected file is
1975 lib/silcclient/idlist.h.
1977 * Irssi SILC Client sets the nicknames in nick@hostn format.
1978 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1979 irssi/src/silc/core/silc-core.c.
1981 The WHOIS printing now also shows both the real nickname and
1982 the formatted nickname so that user knows how to access the
1983 user if there are multiple same nicknames cached. Affected
1984 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1985 printing formatting too to take the hostname now as a separate
1986 argument. The Affected file is
1987 irssi/src/fe-common/silc/modules-formats.[ch].
1989 * Changed the silc_client_get_clients_local to accept the formatted
1990 nickname as argument. It accepts the real nickname too but the
1991 formatted nickname can be used to find the true entry from
1992 multiple entries. Affected file lib/silcclient/silcapi.h and
1993 lib/silcclient/idlist.c.
1995 * Added nickname_format_parse field to the SilcClientParams.
1996 It is a callback function provided by the application to parse
1997 the nickname out of the formatted nickname string. The library
1998 calls it to get the nickname from the formatted string. Since
1999 the application generally knows better the format of the nickname
2000 string it parses it instead of the library, even though library
2001 encodes the formatted string. If the callback function is not
2002 provided then the library will use the string as is. The
2003 affected file is lib/silcclient/silcapi.h.
2005 * All the nickname strings passed to the client library in
2006 commands are now expected to be formatted nickname strings.
2007 If the command does not support the formatted nickname string
2008 it will assume that the sent string is the actual nickname.
2009 Affected file lib/silcclient/command.c.
2011 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2013 * Added public key authentication support to OPER and SILCOPER
2014 commands in the client library. Affected file is
2015 lib/silcclient/command.c.
2017 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2019 * Changed the get_auth_methdod client operation to be asynchronous.
2020 It can be async if the application resolves the authentication
2021 method from the server during the negotiation. Added new
2022 SilcGetAuthMeth completion callback that the application will
2023 call after resolving the authentication method.
2025 Added function silc_client_request_authentication_method that
2026 the application can use to resolve the authentication method
2027 from the server. Added also SilcConnectionAuthRequest callback
2028 that the library will call after the server has replied. The
2029 application can call this function if it does not know the
2030 current authentication method.
2032 Affected files are lib/silcclient/client.c and
2033 lib/silcclient/silcapi.h.
2035 * The Irssi SILC client now automatically resolves the authentication
2036 method incase any configuration information is not present (and
2037 currently there never is). The affected file is
2038 irssi/src/silc/core/client_ops.c.
2040 * Fixed public key authentication from the client library.
2041 Affected file lib/silcclient/protocol.c. Changed also the
2042 protocol specification about the public key authentication in
2043 the connection authentication protocol. The actual data to be
2044 signed is now computed with a hash function before signing.
2046 * Fixed the public key authentication from the server as well.
2047 Affected file silcd/protocol.c.
2049 * Removed the mlock()'s from the memory allocation routines.
2050 Affected file lib/silcutil/silcmemory.c. The ./configure does
2051 not check anymore for the mlock(). Affected file is
2054 * Fixed USERS command in server to allow the execution of the
2055 command for private and secret channels if the client sending
2056 the command is on the channel. Affected file silcd/command.c.
2058 * Fixed silc_client_get_clients_local to return the clients
2059 count correctly. It could return wrong value. Affected file
2060 lib/silcclient/idlist.c.
2062 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2064 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2065 types. The assembler optimizations seemed not to like 64-bit
2066 data types. The assmebler optimizations thus are now enabled
2067 also for BSD systems as opposed to only enable them for Linux.
2069 * Do not check for threads at all on BSD systems. Affected
2070 file configure.in.pre.
2072 * Removed -n and -h options from the Irssi SILC Client since
2073 they are not used in silc.
2075 * Fixed the prime generation to assure that the first digit
2076 of the generated random number is not zero since our conversion
2077 routines does not like number strings that starts with zero
2078 digit. If zero digit is seen the random number is regenerated.
2079 This caused some corrupted RSA keys when the zero first digit
2080 was met. Affected file lib/silcmath/silcprimegen.c.
2082 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2084 * Fixed WIN32 configuration in the ./configure script.
2085 Fixed to include xti.h on environments that has it.
2086 Patches by Carsten Ilchmann and andrew.
2088 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2090 * Changed the silc_id_create_client_id to be collision
2091 resistant. It is now assured that there cannot be created
2092 two same client ID's. I suspect that some weird bugs in
2093 the server were actually caused by duplicate Client IDs.
2094 Affected file silcd/serverid.[ch]. A router receiving
2095 new ID now also assures and informs the sending server
2096 if the ID caused collision.
2098 * Changed the silc_id_create_channel_id to also assure that
2099 there are no collisions.
2101 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2103 * Statement about ignoring the Mutual Authentication flag when
2104 performing rekey with PFS was a bit misleading. It is ignored
2105 if it was set in the initial negotiation, it cannot be even
2106 set in the rekey. Fixed in the ke-auth draft. Started the
2107 new versions of the protocol drafts in the doc/.
2109 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2111 * Fixed a bug in silc_client_command_identify_save when saving
2112 new channel information. The channel name was no duplicated
2113 and caused crash on exit. Affected file is
2114 lib/silcclient/command_reply.c.
2116 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2118 * Fixed the getkey command handling in the server. Send just
2119 empty OK reply to the sender if the key could not be fetched
2120 (but everything else was ok, like the key just was not available).
2121 Changed the public key parameter to optional in the protocol
2122 specs so that empty OK reply can be sent. Affected file
2125 Added a message to Irssi SILC client to tell to user if the
2126 server did not return a public key.
2128 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2130 * Fixed a channel key regeneration bug. It registered new
2131 timeout tasks exponentially until all system resources were
2132 used. Affected file silcd/server.c.
2134 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2136 * Added the SILC Document generator to the scripts/silcdoc.
2137 It can be used to generate the Toolkit Reference Manual out
2138 of the source tree. Internally it will also use the RoboDoc
2139 generator now imported in util/robodoc.
2141 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2143 * Added couple of return's in rekey protocol if error orccurred
2144 during the protocol. The execution must be terminated.
2145 Affected file silcd/protocol.c. Also, terminate the protocol
2146 always with timeout.
2148 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2150 * The client's Client ID was created initally from the wrong
2151 nickname (it could have been in format nick@host) in the
2152 silc_server_new_client. Affected file silcd/packet_receive.c
2154 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2156 * Added some SILC_LOG_ERROR's to various error conditions
2157 if client could not be added to ID cache. Affected files
2158 silcd/packet_receive.c and silcd/server.c.
2160 * When client's sock->user_data is freed, NULL also the
2161 client->router and client->connection pointers. Added check
2162 for these pointers being NULL to various places around the
2163 code. Affected file silcd/server.c.
2165 * Added client->data.registered == TRUE checks to various
2166 places around the code to assure that unregistered client's
2167 are not handled when it is not allowed. Affected file
2170 * Added `bool registered' fields to all
2171 silc_idlist_[server|client]_get_* routines to indicate whether
2172 the fetched client needs to be registered or not. Affected
2173 file silcd/idlist.[ch].
2175 * Add your own entry as registered to the ID cache in the
2176 server. Affected file server.c.
2178 * Fixed a bug in silc_server_new_server. The SilcServer was
2179 set as the new server's context instead of SilcServerEntry.
2180 This naturally caused some weird bugs.
2182 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2184 * Do not delete the channel rekey task when adding it
2185 for in silc_server_create_channel_key.
2187 * Changed the silc_server_create_channel_key to return
2188 TRUE or FALSE to indicate the success of the channel key
2191 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2193 * Fixed MSVC++ project files and added missing files to

2199 does not have it defined. Affected files are
2200 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2202 * Fixed buffer overflow from Irssi SILC Client. Affected
2203 file irssi/src/fe-common/core/themes.c.
2205 * Fixed double free in client library in the file
2206 lib/silcclient/client.c when disconnecting from server.
2208 * Applied double free patch from cras to Irssi SILC client.
2209 Affected files irssi/src/core/[modules/expandos].c
2211 * Fixed the disconnection handling to Irssi SILC Client.
2212 The application must call silc_client_close_connection
2213 in ops->connect client operation in case of failure of
2214 the connection. Affected file is
2215 irssi/src/silc/core/client_ops.c.
2217 * Do not set sock->protocol to NULL in the function
2218 silc_client_close_connection after executing the protocol's
2219 final callback since the sock might not be valid anymore.
2220 Affected file lib/silcclient/client.c.
2222 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2224 * Do not enable SILC_THREADS if the linking with libpthread
2225 did not happen. Affected file configure.in.pre.
2227 * Added notion to protocol specification that server must
2228 verify the sent authentication payload with CMODE when
2229 setting the channel founder key. Implemented it to the
2230 server. Affected file silcd/command.c.
2232 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2234 * Added _EXTRA_DIST SILC distribution variable to the
2235 distributions file. It is used to conditionally add extra
2236 files or directories to the specific distribution. Affected
2237 files ./prepare, Makefile.am.pre and distributions.
2239 Removed the `_' from the start of the distribution names.
2242 * Added README.WIN32 for instructions to compile the Toolkit
2245 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2247 * Fixed a double free in disconnection in the server. Affected
2248 file is silcd/server.c.
2250 * Fixed the lib/silcske/groups.c to work now also with GMP
2251 MP library. The string conversion did not work when using
2252 specific base and the base is indicated in the string as well.
2254 * Created win32/ directory which now includes MSVC++ specific
2255 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2256 It will appear only in the toolkit distribution
2258 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2260 * Changed the key material distribution function in case when
2261 the hash output is too short. The data is now concatenated
2262 a bit differently than it used to. Made the change to the
2263 SKE protocol specification.
2265 * Added better GMP detection to configure.in.pre. A patch
2268 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2270 * Fixed a minor bug in SKE that might cause some problem on
2271 some platforms. Affected file lib/silcske/silcske.c.
2273 * Added the cookie checking for initiator in the SKE. It checks
2274 that the responder returns the sent cookie unmodified. The
2275 affected file is lib/silcske/silcske.c. Added new SKE
2276 error type INVALID_COOKIE that can be sent during the
2277 negotiation. Fixed some memory leaks as well.
2279 * Added the "invalid cookie" error message to Irssi SILC client's
2282 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2284 * Added `task_max' field to the SilcClientParams to indicate
2285 the maximum tasks the scheduler can handle. If set to zero,
2286 default values are used. Affected file lib/silcclient/silcapi.h.
2288 * Fixed memory leaks in silc_client_close_connection. Affected
2289 file lib/silcclient/client.c.
2291 * Added silc_client_del_client_entry to client library to free
2292 all memory of given client entry. Affected file is
2293 lib/silcclient/idlist.[ch].
2295 * Added new functions silc_client_del_channel and
2296 silc_client_del_server to delete channel and server entries.
2297 Affected file lib/silcclient/[silcapi.h/idlist.c].
2299 * Removed silc_client_del_client_by_id from silcapi.h.
2301 * Fixed the INFO command to return the server's own info
2302 correctly when querying by Server ID. Affected file is
2305 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2307 * Removed the non-blocking settings in WIN32 code in the
2308 silc_sock_[read/write] and added SleepEx instead. Affected
2309 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2310 of input data is now checked with FIONREAD and ioctlsocket.
2312 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2314 * Call silc_schedule_task_del_by_context in the
2315 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2316 Affected file lib/silccore/silcprotocol.c.
2318 * Call silc_protocol_cancel for active protocols in the
2319 silc_server_close_connection if the funtion
2320 silc_server_free_sock_user_data has not been called.
2321 Affected file silcd/server.c.
2323 * Generic tasks cannot be deleted using the del_by_fd
2324 task deleting function since generic tasks does not match
2325 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2327 * Added a notion to SILCOPER help file that the SILCOPER works
2328 only on router server, not on normal server.
2330 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2332 * Added for WIN32 support for the new scheduler as well.
2333 Affected file lib/silcutil/win32/silcwin32schedule.c.
2335 * Fixed the SHA1 implementation to work on various platforms.
2337 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2339 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2340 API. It is part of the scheduler now. Everything else is
2341 as previously but some functions has changed their names.
2342 Checkout the lib/silcutil/silcschedule.h for the interface.
2343 Updated all applications to use the new interface. Affected
2344 files are lib/silcutil/silcschedule.[ch].
2346 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2348 * Found a bug in the SKE implementation. The HASH value,
2349 specified by the protocol, was not computed correctly. The
2350 public key of the responder was not added to the computation
2351 even though it is mandatory. Affected file lib/silcske/silcske.c.
2352 This unfortunately causes incompatibilities with older
2353 clients and servers.
2355 * Added WIN32 specific network init and uninit functions:
2356 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2357 the Winsock2. Affected file lib/silcutil/silcnet.h and
2358 lib/silcutil/win32/silcwin32net.c.
2360 * Set the socket always to nonblocking mode on WIN32 after
2361 reading data or writing data. Affected file is
2362 lib/silcutil/win32/silcwin32sockconn.c.
2364 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2366 * Fixed various compilation problems under WIN32. Affected
2367 files lib/silcutil/win32/silcwin32thread.c and
2368 lib/silcutil/win32/silcwin32schedule.c.
2370 * Removed all _internal.h #includes from public header
2371 files. Internal headers must never be included from
2374 Removed also the lib/silcske/payload_internal.h file.
2376 * All include files that may be needed (public and some others
2377 included by the public headers) by application developers are
2378 now copied to the ./includes directory. It does not copy any
2379 internal headers. Affected file Makefile.defines.pre and all
2380 Makefile.am's under lib/ and subdirs.
2382 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2384 * Do not change the ~/.silc directory's permissions automatically.
2385 Affected file irssi/src/silc/core/clientutil.c.
2387 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2389 * Do not cancel the protocol in silc_server_close_connection
2390 it might cause recursion. Now cancelled in the function
2391 silc_server_free_sock_user_data. Affected file silcd/server.c.
2393 * Fixed the silc_server_remove_clients_by_server to regenerate
2394 the channel keys correctly finally. Added also new function
2395 silc_server_remove_clients_channels to actually do it.
2396 Affected file silcd/server.c.
2398 * Fixed the silc_server_new_channel to not crash by giving
2399 wrong router to the new channel. Affected file is
2400 silcd/packet_receive.c.
2402 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2404 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2405 which is given as argument to the silc_client_alloc now.
2406 It can be used to configure the client and set various parameters
2407 that affect the function of the client.
2409 * The USERS command in server did not check whether the channel
2410 is private or secret. Affected file silcd/command.c.
2412 * Added new argument to the USERS command in protocol specification.
2413 The USERS command now can take the channel name as argument
2414 as well. Added support for this in client and server and
2415 updated the protocol specs.
2417 * Completed the GETKEY command in client. It can be now used
2418 to fetch also servers public key not only some clients.
2419 Affected files lib/silcclient/command[_reply].c.
2421 * Added silc_client_get_server to return server entry by the
2422 server name. Affected files lib/silcclient/silcapi.h and
2425 * Redefined the IDENTIFY command in protocol specification to be
2426 more generic. It now can be used to query information about
2427 any entity in the SILC Network, including clients, servers and
2428 channels. The query may be based either the entity's name
2429 or the ID. Added support for this in both client and server.
2431 Affected files silcd/command.c and lib/silcclient/command.c
2432 and command_reply.c.
2434 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2435 the _from_client and _from_server functions. Affected file
2438 * Added silc_client_get_channel_by_id_resolve to the file
2439 lib/silcclient/silcapi.h to resolve channel information by
2440 its ID. Added also silc_client_get_channel_by_id that
2441 does not resolve it from the server.
2443 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2445 * Added SilcServerEntry context into the client library
2446 to represent one server. The INFO command now allocates
2447 these to save the resolved server info. For now on the
2448 client library will also keep information about servers,
2449 connected and resolved with INFO.
2451 The INFO command now allocates the SilcServerEntry context
2452 and saves the server info there. The COMMAND_REPLY in
2453 the INFO now returns the parameters to application in
2454 same order as defined in the protocol specification.
2456 The entries are cached in the client->server_cache.
2458 * The INFO command is now issued after received the Client ID
2459 from the server. Affected file lib/silcclient/client.c.
2461 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2462 to the application as the mode changer might be server.
2463 It is guaranteed that NULL is not returned anymore to the
2464 application. Affected file lib/silcclient/client_notify.c.
2466 The ID Type is now also passed to the application so that
2467 it can check whether the returned entry is SilcClientEntry
2470 Added new function silc_client_get_server_by_id to return
2471 the server entry by ID. Affected files are the
2472 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2474 * Do not create the channel in the Irssi SILC Client when issuing
2475 the JOIN command but when received the sucessful JOIN command
2476 reply. Otherwise the channel might get created even though we
2477 could not join it. The Affected file is
2478 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2480 * Fixed a channel joining bug in router. The router must also
2481 check the channel modes, invite and ban lists etc. when serving
2482 the JOIN command sent by normal server. Affected file is
2483 silcd/command.c. The router now resolves the client's
2484 information from the server who sent the JOIN command if it
2485 does not know it, and processes the JOIN command only after
2488 * Changed the SilcCommandCb to take new argument; void *context2.
2489 Affected file lib/silccore/silccommand.h
2491 The second argument in the command callbacks in the server now
2492 includes the SilcServerCommandReplyContext if the command was
2493 called as pending command callback from the command reply.
2494 Otherwise it is NULL. When called as pending the status of the
2495 command reply will be checked and if it was erronous the
2496 error will be sent to the original sender of the command.
2497 This way the client always receives the error messages even
2498 though the server was actually the one who received the error
2499 when it resent the command to router, for example. Affected
2500 files silcd/command[_reply].[ch].
2502 * Fixed sending WHOWAS command's error message to client if
2503 the requested client could not be found. It was missing.
2506 * Changed the CMODE and CUMODE commands reply arguments in the
2507 protocol specification. The Channel ID is now sent in both
2508 of the commands to identify the channel. Implemented this
2509 new feature to the client and server. Affected files
2510 lib/silcclient/command_reply.c and silcd/command.c.
2512 * Made better checks for invite and ban lists in the JOIN
2513 command in server. Affected file silcd/command.c.
2515 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2517 * The server now performs the incoming host IP/DNS lookup
2518 using the silc_socket_host_lookup and thus does not block
2519 the server anymore. Affected file silcd/server.c.
2521 * Completed the multi-thread support for SILC Scheduler in
2522 the lib/silcutil/silcschedule.c.
2524 * Fixed the configure.in.pre to detect the pthread correctly
2527 * Fixed a deadlock in silc_task_queue_wakeup in the file
2528 lib/silcutil/silctask.c.
2530 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2532 * Added new function silc_schedule_wakeup that is used in
2533 multi-threaded environment to wakeup the main thread's
2534 schduler. It needs to be used when a thread adds a new task
2535 or removes a task from task queues. After waking up, the
2536 scheduler will detect the task queue changes. If threads
2537 support is not compiled in this function has no effect.
2538 Implemented the wakeup mechanism to both Unix and WIN32
2539 systems. Affected files are lib/silcutil/silcschedule.[ch],
2540 lib/silcutil/unix/silcunixschedule.c and the
2541 lib/silcutil/win32/silcwin32schedule.c.
2543 * Added new function silc_task_queue_wakeup to wakeup the
2544 scheduler by the specified task queue. Affected file
2545 lib/silcutil/silctask.[ch].
2547 * The silc_socket_host_lookup_start now wakes up the scheduler
2548 after adding the timeout task. Affected file is
2549 lib/silcutil/silcsockconn.c.
2551 * The silc_socket_host_lookup is synchronous now if the threads
2552 support is not compiled in. However, the callback is still
2553 called asyncronously through the scheduler, anyway. Affected
2554 file lib/silcutil/silcsockconn.c.
2556 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2558 * Added new function silc_socket_host_lookup to perform
2559 asynchronous IP and FQDN lookups for the socket connection.
2560 Affected files lib/silcutil/silcsockconn.[ch].
2562 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2564 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2565 that may or may not compile the mutex support in.
2567 Changed the silc_mutex_alloc interface. It allocates the
2568 mutex now to the sent pointer and returns TRUE or FALSE.
2570 Affected file lib/silcutil/silcmutex.h.
2572 * Wrote the SILC Task Queue interface to support multi-threads.
2573 Affected file lib/silcutil/silctask.[ch].
2575 * Wrote the SILC Scheduler to support multi-threads. Affected
2576 file lib/silcutil/silcschedule.c.
2578 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2580 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2581 in lib/silcutil/win32/.
2583 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2585 * Defined SILC Mutex API and SILC Thread API and implemented
2586 them for Unix. Affected files are
2587 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2588 lib/silcutil/unix/silcunixmutex.c and
2589 lib/silcutil/unix/silcunixthread.c.
2591 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2593 * Fixed the silc_server_remove_clients_by_server's channel
2594 key re-generation. The hash table handling was incorrect
2595 and would not work with many channels. Affected file is
2598 * Fixed some memory leaks around the server code.
2600 * Rewrote the silc_server_get_users_on_channel to support IPv6
2601 based Client ID's. Affected file silcd/server.c.
2603 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2604 specification. However, a separate document must be written
2605 to define the detailed signing procedure and the payload
2606 associated with the flag. Defined the flag to the
2607 lib/silccore/silcchannel.h as well.
2609 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Changed the dynamic tables to static size tables in the
2612 lib/silccrypt/silchmac.c.
2614 * Removed GCC dependencies from the code. A patch by cras.
2616 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2618 * Do not show the error "Error receiving packet bla bla"
2619 in server if it really was not an error (-2 means that reading
2620 is pending). Affected file silcd/server.c.
2622 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2624 * Fixed a possible crash in silc_server_remove_clients_by_server
2625 in silcd/server.c. Fixed there also some memory leaks.
2627 * Fixed the silc_idlist_replace_client_id. It could replace
2628 wrong key in the hash table. Affected file silcd/idlist.c.
2630 * Do not check whether there are global users on the channel
2631 if the channel->global_users is FALSE. Affected functions
2632 silc_server_remove_from_one_channel and
2633 silc_server_remove_from_channels in silcd/server.c. Also,
2634 do not check if the removed client is local as we can be
2635 sure that global client was not removed from the channel
2636 and checking for global users is not needed.
2638 * The silc_server_remove_clients_by_server now re-generates
2639 the channel keys correctly for those channels that had
2640 clients removed from them. Affected file silcd/server.c.
2642 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2644 * Found the reason of random crashes in the server. We weren't
2645 ignoring the SIGPIPE signal (which can be sent in write())
2646 and it crashed the server. Affected file silcd/silcd.c.
2648 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2650 * Assure that sock->user_data is not NULL in the function
2651 silc_server_packet_send in silcd/packet_send.c.
2653 * Disconnect the remote connection if it could not be added
2654 to any ID lists in the server. The affected file is
2657 * Check in silc_server_packet_send[_real/dest] that the
2658 socket is not disconnecting and ignore the data if it is.
2659 Affected file silcd/packet_send.c.
2661 * Define inline to __inline on native WIN32 compilation.
2662 Affected file includes/silcwin32.h.
2664 * Added some explicit type casts for inline code since MSVC
2665 require them. Affected files lib/silcutil/silcbuffer.h,
2666 lib/trq/silcdlist.h and lib/trq/silclist.h.
2668 * Print warning in log files from now on if the packet
2669 decryption fails. Affected file silcd/server.c.
2671 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2673 * Changed the `say' client operation's interface to accept
2674 new `type' argument to indicate the type of the message sent
2675 by the library. The application may filter the library's
2676 messages according the type. The affected file is the
2677 lib/silcclient/silcapi.h.
2679 * Added two new functions to lib/silcclient/silcapi.h:
2680 silc_client_del_client and silc_client_del_client_by_id.
2681 Affected file lib/silcclient/idlist.c.
2683 * Moved the clientincludes.h from includes/ to silc/ and
2684 serverincludes.h from includes/ to silcd/.
2686 * The modes for the CMODE and CUMODE are now passed as
2687 uint32 for application with COMMAND_REPLY. The affected
2688 file is lib/silcclient/command_reply.c.
2690 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2692 * /WHOIS without arguments shows client's own information.
2693 Affected file lib/silcclient/command.c.
2695 * Changed PING to not accept any arguments. The specs
2696 says that client can ping only the connected server so
2697 requiring an argument is not needed. Affected file is
2698 lib/silcclient/command.c.
2700 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2702 * Fixed a fatal bug in private message sending and reception
2703 encryption and decryption when using private message keys.
2704 The implementation was incorrect and did not follow the
2705 specification. It causd that some of the message were
2706 lost since it did not use the sending and receiving keys
2707 as the protocol suggests. This has been fixed and will cause
2708 incompatibilities with older clients when sending private
2709 message encrypted with private message keys. Affected files
2710 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2711 and various other in Irssi SILC Client.
2713 Added `responder' boolean argument to the functions
2714 silc_client_add_private_message_key[_ske] to indicate when
2715 the key is added as responder or initiator of the key
2718 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2720 * Removed the silc_ske_check_version function and created
2721 a SilcSKECheckVersion callback. Added also a function
2722 silc_ske_set_callbacks that is now used to set all SKE
2723 callbacks. The callback functions are not given to
2724 the SKE functions anymore, but this function is used to
2727 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2729 * Added `silc_version' argument to the silc_client_alloc
2730 to define the version of the application for the library.
2731 The library will use the version string to compare it
2732 against the remote host's (usually a server) version
2733 string. Affected file lib/silcclient/silcapi.h
2735 * Added the KE protocol context to Key Agreement context
2736 in client library so that we can abort the SKE if it
2737 is in process when we get timeout. Affected file is
2738 lib/silcclient/client_keyagr.c.
2740 * Do not resolve the client ID forever if it returns in the
2741 first time that such client does not exist. This was done
2742 for example with private message. Affected file is
2743 lib/silcclient/client_prvmsg.c.
2745 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2747 * Do not add regex.h for WIN32. The affected file
2748 includes/silcincludes.h.
2750 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2751 not work yet 100%. It generates the DLL's automatically
2752 when compiling with --with-win32 under cygwin.
2754 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2756 * lib/contrib/regex.c is not compiled on WIN32.
2758 * Added silc_net_get_socket_opt function to the
2759 lib/silcutil/silcnet.h.
2761 * Added includes/silcwin32.h for WIN32 specific includes
2764 * Do not use ptime structure or any of the posix process
2765 functions on WIN32 in lib/silccrypt/silrng.c.
2767 * Added silc_gettimeofday to provide generic function
2768 for struct timeval on all platforms. Added the function
2769 to lib/silcutil/silcutil.h.
2771 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2773 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2774 library as they clearly belong there. As a plus side we
2775 can make the actual socket connection routines platform
2778 Added also new generic function silc_socket_read and
2779 silc_socket_write (that used to be silc_packet_[read/write].
2780 The implementation of these are platform specific.
2782 * Added WIN32 specific routines of silc_socket_[read/write]
2783 to lib/silcutil/win32/silcwin32sockconn.c.
2785 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2787 * Added preliminary support for native WIN32 compilation under
2788 cygwin (using the -mno-cygwin option for GCC) to the
2789 ./configure.in.pre. The --with-win32 now prepares the
2790 compilation for native WIN32.
2792 * Rewrote the SILC Scheduler interface in the file
2793 lib/silcutil/silcschedule.h. The scheduler is now context
2794 based and does not have anymore any global static scheduler.
2795 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2796 and created lib/silcutil/win32 directory for WIN32 based
2799 * Added Unix specific network routines to the
2800 lib/silcutil/unix/silcunixnet.c and the old
2801 lib/silcutil/silcnet.c includes now only generic routines.
2803 Added WIN32 specific network routines to the
2804 lib/silcutil/win32/silcwin32net.c.
2806 * Added Unix specific utility functions from the
2807 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2809 * Added WIN32 SILC Scheduler to the file
2810 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2813 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2815 * Do not handle JOIN notify in the server if the target client
2816 is not registered (idata->registered == FALSE). The affected
2817 file is silcd/packet_receive.c.
2819 * Update the nickrec->founder in event_cumode in the Irssi SILC
2820 client. Affected file irssi/src/silc/core/silc-channels.c.
2822 * Fixed the CUMODE_CHANGE notify handling in the server when
2823 server and router are announcing their clients on channels.
2824 Now the mode changes are saved and notified correctly. The
2825 affected file is /silcd/packet_receive.c.
2827 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2828 They really did not replace the cache entry in the ID Cache.
2829 Now they do that. Affected file silcd/idlist.c.
2831 * Fixed the KICK notify handling in the Irssi SILC client to
2832 update the channel records so that the kicked client does not
2833 appear to be on the channel. The affected file is
2834 irssi/src/silc/core/silc-channels.c.
2836 * Always update the conn->current_channel when executing command
2837 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2839 * Fixed the KILL notify handling in Irssi SILC client to remove
2840 the killed client on all channels.
2842 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2844 * Fixed the silc_parse_command_line to remove extra spaces
2845 from the start and end of the arguments. Affected file is
2846 lib/silcutil/silcutil.c.
2848 * Cancel and free any active protocol in the function
2849 silc_server_close_connection. Affected file silcd/server.c.
2851 * Cancel and free any active protocol in the function
2852 silc_client_close_connction. Affected file is
2853 lib/silcclient/client.c.
2855 * Do not execute the KILL command for clients that are in
2856 history (ie. they are not in the network). Affected file is
2859 * Fixed KILL notify handling, client does not crash anymore.
2860 Affected file irssi/src/silc/core/silc-channels.c.
2862 * Reduced the default packet buffer size from 2048 to 1024 in
2863 lib/silccore/silcpacket.c.
2865 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2866 counter to the SKE context that is incresed when the SKE library
2867 performs async operation outside the library. If the outside
2868 process frees the SKE context and FREED status will be set
2869 and the library will detect after the sync operation that the
2870 libary is freed. The affected files are
2871 lib/silcske/silcske[_status].[ch].
2873 * Resolve the client entry information in the function
2874 silc_client_channel_message to assure that NULL pointer is not
2875 passed as client entry to the application. */
2877 * Fixed the task timeout calculation to assure that there is
2878 never negative timeouts. The affected file is
2879 lib/silcutil/silcschedule.c.
2881 * Fixed the channel user mode notification sending in server.
2882 It was sent point-to-point to the router (or to server by router)
2883 but it needs to be destined to a channel. The routines now
2884 supports sending the channel user mode notifys to the channels
2885 when announcing clients and channels. Affected files are
2886 silcd/server.c and silcd/packet_receive.c.
2888 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2889 It did not actually replace the old channel entry in the cache.
2890 Affected file lib/silcclient/client_notify.c.
2892 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2894 * Fixed a possible crash in silc_packet_send_prepare. It now
2895 assures always that there is enough space in the buffer and
2896 at the tail area of the buffer (for MAC).
2898 Fixed the inbound buffer reallocation in silc_packet_read.
2899 It was old code and did not handle the reallocation correctly.
2902 The affected file is lib/silccore/silcpacket.c.
2904 * Fixed buffer overflow in silc_parse_nickname in the file
2905 lib/silcutil/silcutil.c.
2907 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2909 * make install generates new server keys only if there is not
2912 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2914 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2915 Added check that if the NOREPLY is set then we will not send
2916 the away message. This avoids infinite loop of away messages
2917 if both clients are away. The affected file is
2918 lib/silcclient/client_prvmsg.c.
2920 * Fixed client crash if /NICK was given without arguments.
2921 Affected file lib/silcclient/command.c.
2923 * Server does not send the invite list in INVITE command back
2924 to the client if the list was not altered. Added this notion
2925 to the protocol spec as well. Affected file silcd/command.c.
2927 Fixed possible crash in INVITE command by checking the
2928 value of silc_server_get_client_route command.
2930 * Fixed the INVITE notify type handling. The arguments are now
2931 taken in correct order and client does not crash. The affected
2932 file is irssi/src/silc/core/silc-channels.c.
2934 Removed the "Inviting xxx to channel" message from the
2935 client library away and let the application handle it.
2936 Affected file lib/silcclient/command.c. Added that message
2937 to Irssi SILC client's message formats.
2939 * Fixed CMODE command crash in client. It now checks the
2940 amount of arguments correctly and does not crash. The affected
2941 file is lib/silcclient/command.c.
2943 * Do not create new channel automatically in silc_channels_join
2944 but check whether the channel by that name already exists.
2945 Affected file irssi/silc/core/silc-channels.c.
2947 * Do not send the SERVER_SIGNOFF to router if the disconnected
2948 entity was the router. Affected file silcd/server.c.
2950 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2951 SILC client as it was missing from there.
2953 Added the handling of the KICK notify to the Irssi SILC client
2954 as it was missing. Added "you have been kicked" message to
2955 Irssi SILC client's message modules formats.
2957 Added the handing of the KILL notify to the Irssi SILC client
2958 as it was missing. Added the kill message module formats
2961 The affected file is irssi/src/silc/core/silc-channels.c.
2963 * The router did not save the channel mode the server announced.
2964 Affected file silcd/packet_receive.c.
2966 * Fixed a possible crash in INFO command in server. If the
2967 server did not provide the server info it crashed. Affected
2968 file silcd/command.c.
2970 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2972 * Fixed the GETKEY command in the server to check also the
2973 global list. Otherwise the GETKEY would not work correctly
2974 in normal SILC server. Affected file silcd/command.c.
2976 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2978 * Fixed GETKEY crash, it crashed if the command did not succseed.
2980 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2982 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2983 is now real and not just an macro interface to GMP.
2985 Removed the entire GMP from the source tree and imported new
2986 NSS MPI library instead. Reason for removing GMP is that it is
2987 extremely large and compiles extremely slow. The NSS MPI
2988 is only a few files and compiles in less than 10 seconds.
2989 The speed is also about the same as GMP. The MPI is imported
2990 to lib/silcmath/mpi.
2992 If the system has GMP installed we will still use the GMP.
2993 If it is not then the NSS MPI will be compiled.
2995 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2997 * Merged a long nickname (127 characters long) crash bugfix from
2998 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3000 * Merged a freed memory reference bugfix from Irssi CVS tree.
3001 Affected file irssi/src/core/commands.c.
3003 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3005 * Added the server's public key sving and verification to the
3006 server when performing the SKE. This was missing and the
3007 remote server's (or router's) public key was accepted without
3008 checking whether we have it previously or trust it at all.
3009 Affected file silcd/protocol.c.
3011 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3013 * Check in the silc_server_timeout_remote if protocol is active
3014 and make sure that the protocol's final callback is called so
3015 that all memory if freed. Affected file silcd/server.c.
3017 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3019 * silc_server_whois_send_reply crashed the server if the nickname
3020 was 127 characters long. Affected file silcd/command.c.
3022 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3024 * Added sanity check to the silc_server_new_client. If the hostname
3025 is provided inside username then check that the provided hostname
3026 really is the same as the resolved one. If the hostname was not
3027 resolved then check it from the public key. Affected file is
3028 silcd/packet_receive.c.
3030 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3031 if the server disconnected us and the connection is not valid
3032 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3034 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3035 the library to the lib/silcutil/silcutil.[ch].
3037 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3039 * Close log file after open. Affected file
3040 lib/silcutil/silclog.c.
3042 * Check whether sock == NULL in silc_client_send_packet and return
3043 if it is. Affected file lib/silcclient/silcclient.c.
3045 * Check rec->entry == NULL in the Irssi SILC Client before
3046 sending the channel message. Affecte file is
3047 irssi/src/silc/core/silc-servers.c.
3049 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3051 * Merged a splitted window bugfix from Irssi CVS tree. The
3052 affected file is irssi/src/fe-text/textbuffer-view.c.
3054 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3055 It did not print nickname.
3057 * Improved the distributions system a bit.
3059 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3061 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3062 irssi/src/fe-text/gui-window.c.
3064 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3065 to in-active server. The affected file is
3066 irssi/src/silc/core/client_ops.c.
3068 * Resolve the client in USERS command reply if the entry does
3069 not have username resolved. The affected file is
3070 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3071 command to WHOIS command to really resolve stuff. The USERS
3072 is not used any more in any critical section so WHOIS can
3073 be used even though it might be slower than IDENTIFY.
3075 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3078 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3080 * Changed the protocol API a bit more consistent in the
3081 lib/silccore/silcprotocol.[ch].
3083 * Changed the following headers to ROBODoc format:
3085 lib/silccore/silcpayload.h
3086 lib/silccore/silcprotocol.h
3087 lib/silccore/silcsockconn.h
3089 All core library headers are now formatted.
3091 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3093 * Fixed a bug in Irssi SILC client; do not show that you are
3094 server/router operator if you really are not. Affected file is
3095 irssi/src/silc/core/client_ops.c.
3097 * Renamed silc_command_free_payload to silc_command_payload_free.
3098 Affected file lib/silccore/silccommand.h
3100 * Added silcmath.h to include the prototoypes of various routines
3101 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3104 * Changed the following headers to ROBODoc format:
3106 lib/silccore/silcchannel.h
3107 lib/silccore/silccommand.h
3108 lib/silccore/silcid.h
3109 lib/silccore/silcidcache.h
3110 lib/silccore/silcmode.h
3111 lib/silccore/silcnotify.h
3112 lib/silccore/silcpacket.h
3113 lib/silcmath/silcmath.h
3115 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3117 * Added checking to the server code not to start the server if
3118 ciphers and stuff are not configured properly. Affected files
3119 silcd/serverconfig.[h] and silcd/server.c.
3121 * Changed the layout of the header files of the public interfaces
3122 in the SILC libraries. The new layout supports ROBODoc
3123 documentation tool (and some others) so that it is easy to create
3124 a library reference manual. All the other headers and source
3125 code must still follow the CodingStyle document. Also source
3126 code must not include these ROBODoc stuffs, only the headers.
3127 Furthermore, all public interface headers must now be named
3128 by using `silc' prefix, example: silcapi.h, silccipher.h.
3129 Some files were renamed due to this. All the other headers
3130 must not be used as public interfaces. I will update the
3131 CodingStyle document later. Changed following headers, so far:
3133 lib/silcclient/silcapi.h
3134 lib/silccore/silcauth.h
3135 lib/silccore/silcprivate.h
3136 lib/silccrypt/silcdh.h
3138 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3142 * Removed silc_client_packet_send_flush from the client library
3143 as it is not needed. Affected file lib/silcclient/client.[ch].
3145 * Added printing of message of unresolved authentication method
3146 to the Irssi SILC client. Added it to the module formats.
3147 Removed the same message from the client library.
3149 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3151 * Added new distribution feature, DISTLABEL. Every distribution
3152 can define own preprocessor label that can be used in the
3153 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3154 file distributions, acconfig.h.pre and prepare.
3156 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3158 * Added Makefile.defines_int to include the actual definitions
3159 for Makefile.defines.in. Tested the new distribution system,
3160 created distributions and tested installation.
3162 * Added AWAY message printing to the Irssi SILC client. Added
3163 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3165 * Added SCONNECT command to call the SILC's CONNECT command.
3166 Cannot use CONNECT directly since Irssi uses that internally.
3167 Affected file irssi/src/silc/core/silc-servers.c.
3169 Added ACTION local command. It is same as ME command but takes
3170 the channel as mandatory argument.
3172 Rewrote some of the Irssi's help files to suite for SILC
3175 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3177 * Added Makefile.defines[.in] that should for now on be included
3178 in all Makefile.am file in the source tree. That file includes
3179 all common compilation definitions for SILC source tree.
3181 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3183 * Minor changes to the ./prepare script to change the package
3184 name according the distribution name to the configure.in.
3186 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3188 * Created new distribution system. Added file `distributions'
3189 that defines all the distributions that can be created out of
3190 the SILC source tree. The ./prepare script now reads that
3191 file to determine how to prepare the distributions. The
3192 first argument to the ./prepare is the name of the distribution
3193 and second is the version of the distribution. If given
3194 without arguments it creates the default (toolkit) distribution
3195 with the default version (defined in ./prepare).
3197 All Makefile.am files that are subject to the distributions
3198 are now named as Makefile.am.pre. These are ./Makefile.am
3199 and lib/Makefile.am. Others may be changed later.
3201 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3203 * Added invite list, ban list, some key management and connection
3204 error message printing to module formats in the Irssi SILC client.
3206 * Added new silc_client_set_away_message to set the away message
3207 that is back to the person who sent private message. The
3208 affected file lib/silcclient/silcapi.h and the
3209 lib/silcclient/client_prvmsg.c.
3211 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3213 * Fixed the private message sending in the Irssi SILC client,
3214 added local command KEY to the Irssi SILC client.
3216 Added key management and key agreement message formats to the
3217 irssi/src/fe-common/silc/module-formats.[ch].
3219 Added USERS (alias WHO) printing, server/router operator
3220 indication and LIST command printing to the module formats.
3222 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3224 * Fixed channel joining notify handling, cumode notify handling
3225 from Irssi SILC client.
3227 * Added SILC specific module-formats to the Irssi SILC client so
3228 that SILC specific message hilighting, colors etc is possible.
3229 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3231 Added channel mode, channel user mode, actions, notices,
3232 whois and whowas printing to the the module-formats.c.
3234 * Fixed a bug in channel deletion in the server. The channel
3235 is not left to the cache even if the channel founder auth mode
3236 is set when there are no users anymore on the channel. Affected
3237 file silcd/server.c.
3239 * The silc_net_localhost now resolves the entire hostname including
3240 the domain name. Affected file lib/silcutil/silcnet.c.
3242 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3244 * Changed the ask_passphrase client operation to be ascynchronous.
3245 It has now a completion callback and a context that the
3246 application must call after it has got the passphrase from
3247 the user. Affected files lib/silcclient/silcapi.h,
3248 lib/silcclient/protocol.c, lib/silcclient/command.c and
3251 Added SilcAskPassphrase callback that the application calls
3252 to deliver the passphrase to the library.
3254 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3255 The public key verification and especially a certificate
3256 verification is asynchronous procedure.
3258 Added new SILC_SKE_STATUS_PENDING status to indicate the
3259 request is pending and a callback will be called to finalize
3262 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3263 indicate that remote end did not send its public key (or
3264 certificate), even though we require it. Added check for this
3265 condition in the SKE. This was a security bug, now fixed.
3267 Defined new SilcSKEVerifyCbCompletion callback that is called
3268 when the verification process is completed.
3270 The affected files lib/silcske/silcske_status.h and
3271 lib/silcske/silcske.[ch].
3273 * Changed the verify_public_key client operation to be async
3274 as well. Defined SilcVerifyPublicKey callback that is used to
3275 indicate the success of the public key verification process.
3277 Changed the server and client to use the new async client
3280 * Changed the Irssi SILC client's internal scheduler to be called
3281 twice as many times as it used to be. As a result the client
3282 should be a bit faster now. Affected file is
3283 irssi/src/silc/core/silc-core.c.
3285 * Added support to Irssi SILC client of asynchronous public key
3286 verification and passphrase inquiry. Affected file is
3287 irssi/src/silc/core/silc-core.c.
3289 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3291 * Do not say "You have left channel %s" in client library.
3292 Moved it to the application. Affected files are
3293 lib/silcclient/command.c and silc/client_ops.c.
3295 * Fixed silc_client_get_clients. Command context was not
3296 duplicated and was freed memory in the callback. Affected
3297 file lib/silcclient/idlist.c.
3299 * Do not say "you are now talking..." on JOIN command in the
3300 client library. The appliation must handle it.
3302 * Do not say ".. changed topic to" in command reply in the
3303 client libary. The application must handle it.
3305 * Fixed TOPIC command sending in the client library.
3307 * Fixed a memory leak in silc_client_command_free in the file
3308 lib/silcclient/command.c.
3310 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3312 * Imported a modified version of Irssi client to the source tree.
3313 The Irssi will be used to create a new client called
3314 Irssi SILC. Imported to irssi/.
3316 Added silc_core_init_finish function to the Irssi. Affected
3317 file irssi/configure.in.
3319 A lot changes in the Makefile.ams around the irssi tree.
3321 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3323 * Do not rehash if the new size is same as the old size of the
3324 hash table, in the silc_hash_table_rehash*. The affected file
3325 lib/silcutil/silchashtable.c.
3327 * Replaced hash_table_del_by_context calls from the server
3328 (when channel->user_list and client->channels) to the
3329 hash_table_del as it is sufficient and faster.
3331 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3333 * Added silc_hash_table_list, silc_hash_table_get and the
3334 SilcHashTableList structure to provide an alternative way to
3335 traverse the hash table. The affected files are
3336 lib/silcutil/silchashtable.[ch].
3338 * Changed the server's idlist routines to use the hash table
3339 routines to optimize the code.
3341 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3343 * Replaced the client entry's `channel' list and channel entry's
3344 `user_list' list to hash tables for optimized lookup. Changed
3345 the code to use the hash table interface around the code.
3346 Affected file lib/silcd/idlist.[ch].
3348 * Added `auto_rehash' boolean argument to the function
3349 silc_hash_table_alloc to indicate whether the hash table should
3350 auto-rehash when it thinks is appropriate time. It will
3351 increase the hash table size if the there is twice as much
3352 entries in the table than the size of the table, and will
3353 decrease the size if there are twice as less entries than
3354 the size of the table.
3356 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3358 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3360 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * silc_idcache_purge_by_context deletes the entry now by context
3363 as it is supposed to do. Affected file lib/silccore/idcache.c.
3365 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3366 client is not anymore valid (WHOWAS givens the info) and not
3367 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3369 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3371 * Removed the `data' and `data_len' arguments from the ID Cache
3372 interfaces and added `name' argument. ID Cache does not handle
3373 anymore the binary data only a names associated with given ID.
3375 * When hashing a Client ID with silc_hash_id the entire ID is
3376 not hashed anymore, instead only the hash of the Client ID is
3377 hashed. This way we can access the Client ID from the cache
3378 with Client ID but with the hash of the ID (which is a hash of
3379 the nickname) as well without any difference in performance.
3381 Added also silc_idcache_find_by_id_one_ext to do one on one
3382 searching when we have the actual ID. Added also function
3383 silc_hash_client_id_compare. The affected files are
3384 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3386 * When hashing the name associated with a ID it is always done
3387 in lowercase. This way we can access the cache without worrying
3388 about case-sensitivity, even though, for example nicknames are
3391 * Fixed a bug in server with channel message sending. It put
3392 wrong ID type as destination ID. The affected file
3393 silcd/packet_send.c.
3395 * silc_idcache_del_by_context now deletes from all hash tables
3396 by context. Affected file lib/silccore/idcache.c.
3398 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3400 * Changed the client library to use the new ID Cache interface.
3401 Changes around the source tree.
3403 * Added silc_hash_table_rehash_ext to rehash with specific
3404 hash function. Affected file lib/silcutil/silchashtable.[ch].
3406 * Added silc_hash_string_compare to compare two strings in the
3407 hash table. Affected file lib/silcutil/silcutil.[ch].
3409 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3411 * Added new function silc_idcache_del_by_context into the
3412 lib/silccore/idcache.[ch].
3414 * Changed the server's ID list routines to use the new ID Cache
3415 interface. Changes around the source tree.
3417 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3419 * Added silc_hash_table_del[_by_context]_ext functions in to the
3420 lib/silcutil/silchashtable.[ch].
3422 Removed silc_hash_table_find_all* routines and added new
3423 silc_hash_table_find_foreach to replace them.
3425 Added silc_hash_table_replace_ext function as extended
3426 replacing function. Separated the simple hash table interface
3427 from the extended hash table interface in the file
3428 lib/silcutil/silchashtable.h.
3430 * Fixed minor bugs and changed it to use some of the new
3431 hash table functions in lib/silccore/idcache.c
3433 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3435 * Added new function silc_hash_table_find_all to return all keys
3436 in the hash table by the specified key. As the hash table is
3437 collision resistant it also makes it possible to have several
3438 duplicate keys in the hash table. This function may be used to
3439 find all of the keys from the hash.
3441 Added user_context arguments to the SilcHashFunction,
3442 SilcHashCompare and SilcHashDestructor to deliver user specified
3445 Added new fuctions silc_hash_table_find[_all]_ext to do
3446 extended lookup with specified hash and compare functions and
3447 specified user contexts.
3449 Added new function silc_hash_table_add_ext to add the key
3450 with specified hash function and user context.
3452 Added new function silc_hash_table_foreach to traverse all
3453 entrys in the hash table. Added SilcHashForeach callback
3456 Added new function silc_hash_table_del_by_context to delete
3457 the entry only if the context associated with the key matches.
3459 Affected files are lib/silcutil/silchashtable.[ch].
3461 * Removed silc_hash_[server/client/channel]_id and added just
3462 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3463 silc_hash_id_compare to compare two ID's using as the hash table
3464 comparison function. Added also silc_hash_data to hash
3465 binary data and silc_hash_data_compare to compare it.
3467 * Removed silc_idlist_find_client_by_hash as it is not needed
3468 anymore. Affected file silcd/idlist.[ch].
3470 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3471 to use internally the SilcHashTable. The new ID Cache is a lot
3472 faster than the old one. Some of the ID Cache interface was also
3473 rewritten and obsolete and stupid functions were removed.
3475 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3477 * Added entry_count field to the SilcHashTable to keep the number
3478 of the entries in the table. Implemented the function
3479 silc_hash_table_rehash. Added new function
3480 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3482 Fixed a minor bug in silc_hash_table_free.
3484 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3485 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3486 into the lib/silcutil/silcutil.[ch].
3488 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3490 * Implemented a collision resistant hash table into the
3491 lib/silcutil/silchashtable[ch]. See the header and the source
3492 for the SilcHashTable API.
3494 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3496 * Merged dotconf version 1.0.2 into lib/dotconf.
3498 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3500 * Do not compile anything in lib/silcsim/* if the SIM support
3501 is not enabled. The tree should now compile without problems
3504 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3506 * Compiled the SILC under cygwin. Compiled and tested briefly
3507 without problems. More tests needed. The SIMs didn't compile
3510 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3512 * Fixed possible crash in silc_get_username in the
3513 lib/silcutil/silcutil.c.
3515 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3517 * Fixed a va_arg in silc/client_ops.c.
3519 * Oops, RC5 routines were named AES and caused some problems
3520 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3522 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Added new SilcIDIP structure into the lib/silccore/id.h and
3525 replaced the old `ip' fields from all SILC ID's to that type.
3526 This is a step towards IPv6 support.
3528 The silc_id_get_len takes now the ID as an extra argument.
3529 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3530 both IPv4 and IPv6 based ID's.
3532 The affected files are lib/silccore/id.[ch] and other files
3533 around the tree using these routines.
3535 * Removed the ID length arguments in server from various
3536 silc_server_send_notify_* routines -> they are not needed
3539 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3541 * Fixed memory leak in silc_encode_pem_file in the file
3542 lib/silcutil/silcutil.c.
3544 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3546 * Check minor version as well in the SKE. Affected files are
3547 silcd/protocol.c and lib/silcclient/protocol.c.
3549 * Added --identifier option to the server so that an identifier
3550 can be when creating the public key for the server. Affected
3551 file is silcd/silcd.c.
3553 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3554 lib/silccrypt/silcpkcs.c.
3556 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3558 * Register default ciphers and stuff when using -C option with
3559 the server. Affected file sildc/silcd.c.
3561 * Put back the servers public key filename format, it is better
3562 than the new one. For now, the client keys are saved with the
3563 new filename format. The affected file silc/client_ops.c.
3565 * Implemented the Cipher API for the rest of the ciphers that
3566 did not implement it or implemented it the wrong way.
3568 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3570 * Register default ciphers and stuff when using the -S option
3571 in the client. Affected file silc/silc.c. Same also when
3572 creating new key pair with -C option.
3574 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3576 * Fixed the silc_verify_public_key client operation function to
3577 save the public keys differently. The fingerprint is now
3578 used as filename and not the hostname. This way also the
3579 client keys are saved uniquely and not with hostnames. The
3580 affected file is silc/client_ops.c.
3582 * Trimmed the silc_hash_fingerprint function to remove extra
3583 whitespaces from the end of the fingerprint. The affected
3584 file is lib/silccrypt/silchash.c.
3588 * Added silc_cipher_register_default function to register all
3589 default ciphers. It can be used when configuration files
3590 does not exist and the application does not want any specific
3591 ciphers in any specific order.
3593 The SilcDList is now used as silc_cipher_list dynamically
3594 allocated cipher list. Removed the static list all together
3595 and now all ciphers must be allocated to the dynamic list.
3596 The silc_cipher_alloc routine was changed to check only the
3599 All silc_cipher_* routines that used to return int returns
3602 The affected files lib/silccrypt/silccrypt.[ch].
3604 * The same thing was done to silc_hash_* as for silc_cipher_*
3605 routines. Affected files lib/silccrypt/silchash.[ch].
3607 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3608 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3609 Added also silc_pkcs_[un]register[_default] functions.
3610 Removed the data_context from the PKCS API.
3612 * Added silc_hmac_register_default function to register default
3613 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3614 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3615 to unregister all hmacs at once.
3617 * Register the default ciphers, hash functions, PKCSs and HMACs
3618 if client's configuration file does not exist. The affected
3621 * The client did not load the hash functions from the SIM
3622 modules at all. Added support for this. Affected file is
3623 silc/clientconfig.c.
3625 * When decoding public key with silc_pkcs_public_key_decode, check
3626 the supported algorithm only if PKCS are registered. Affected
3627 file lib/silccrypt/silcpkcs.c. The same was done with the
3628 silc_pkcs_private_key_decode.
3630 * Fixed the SILC List routines to keep the list always in order.
3631 It used to change the list's order when traversing the list but
3632 not it preserves the order. Affected file lib/trq/silclist.h.
3634 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3636 * Added the client library to use the SilcSocketConnection's
3637 reference counter (by silc_socket_dup) to prevent the bug that
3638 the socket object may be freed underneath async operation.
3640 * The name resolv library checking fixes in the configure.in.pre.
3643 * Created new version of the protocol drafts for future
3644 development. The -03 drafts are the ones that will be changed
3645 in the trunk now and the -02 will remain as they are.
3647 * Send list of CUMODE notifys to the router when announcing
3648 the channel users to the router. Affected file silcd/server.c.
3649 If the router receiving channel founder CUMODE for a channel
3650 that already has channel founder it will send CUMODE notify
3651 to the sender to remove the channel founder rights from the
3652 announced client. Affected file silcd/packet_receive.c.
3654 * The CUMODE notify may now use Server ID as well as the entity
3655 who changes the mode. Updated protocool specs.
3657 * Updated INSTALL and README files.
3659 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3661 * New web pages in the http://silc.pspt.fi. The pages was
3666 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3668 * Implemented the [DenyConnectin] config section in the server.
3669 Added silc_server_config_denied_conn to check whether incoming
3670 connection is denied. Affected file silcd/serverconfig.[ch].
3672 * Do not check the ports when checking the incoming configuration
3673 data if the port is 0, meaning any. Affected file is
3674 silcd/serverconfig.c.
3676 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * Fixed buffer overflow in silc_string_compare in the file
3679 lib/silcutil/silcutil.c.
3681 * Fixed double free in silc_server_command_leave in the file
3684 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3686 * Fixed the version checking in the server. Affected file is
3689 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3691 * Fixed the configuration data fetching when accepting new
3692 connections in the server. Affected file silcd/server.c.
3694 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3696 * Added `sender_entry' argument to the function
3697 silc_server_packet_relay_to_channel so that we can check
3698 whether some destination actually belongs to the same route
3699 the sender belongs (ie, we must not resend the packet to the
3700 sender). Affected file silcd/packet_send.[ch].
3702 * Added `servername' field to the SilcClientEntry in the server
3703 to hold the name of the server where client is from. Affected
3704 file is silcd/idlist.h.
3706 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * Moved the channel message encrypting in the router betwen
3709 router connections from silc_server_channel_message to the
3710 silc_server_packet_relay_to_channel since we want to check
3711 whether we have anybody channel before encrypting anything.
3712 Affected files silcd/packet_[receive/send].c.
3714 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3716 * Fixed the [AdminConnection] server config section to support
3717 multiple entries. Affected file silcd/serverconfig.c.
3719 * Added support into the server to check the validity of the
3720 incoming connection before executing any KE or authentication
3723 * The connection configuration is now saved to the KE and
3724 connection auth protocol contexts and not fetched anymore in
3725 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3727 * The local hosts listenning address and port is also resolved
3728 now when starting the server. We want to have the socket object
3729 to include the real address and port for the listener. Added
3730 new function silc_net_check_local_by_sock into the files
3731 lib/silcutil/silcnet.[ch].
3733 * Fixed a broadcast bug in server -> do not broadcast if we
3736 * Fixed a routing bug. Do not route broadcast packets ever.
3737 Broadcast packets must be processed always and not routed since
3738 they may be destined to some other host than yourself and thus
3739 would get routed without no good reason. Affected file is
3742 * Added function silc_server_config_is_primary_route to check
3743 whether primary router connection has been configured (a router
3744 configuration that we are initiating). If there is not, we
3745 will assume that there is only two routers in the SILC network
3746 and we will use the incoming router connection as our primary
3747 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3749 * Changed the order of the broadcasting. Broadcast _after_ the
3750 packet has been processed not before. Affected file is
3753 * Fixed a [ClientConnection] parsing bug. The port was never
3754 parsed correctly thus resulting to port 0. Affected file
3755 silcd/serverconfig.c.
3757 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3758 argument and did not set the broadcast packet flag. Affected
3759 file silcd/packet_send.c. Fixed same bug in the function
3760 silc_server_send_notify as well.
3762 * If we receive NEW_ID packet for our own ID in the server, ignore
3765 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3769 * Removed the nickname from the Private Message Payload.
3770 Updated the code and the protocol specs.
3772 * Updated protocol specs for submitting to the IETF.
3774 * Tweaked the Random Number Generator a bit. Affected file
3775 lib/silccrypt/silcrng.c. Exported a new function
3776 silc_rng_[global]_add_noise which can be used to add more
3779 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3781 * Do not parse packets with different timeout when protocol
3782 is active -> may cause problem with rekey. Affected file
3785 * When server receives signoff notify it must not create
3786 new channel key if the client is on any channels since the
3787 sender of the signoff notify will create it.
3789 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3791 * Added printing of error messages during SKE protocol from the
3792 failure packet sent by server during SKE. Affected file
3795 * Removed the client's failure_callback handling with timeout
3796 and handle it immediately when received.
3798 * The SKE library returned wrong type in SUCCESS and FAILURE
3799 packets. They must be 32 bit MSB not 16 bit MSB.
3801 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3803 * Ok, rewrote the logic of the re-key and now it seems to work.
3804 I tested it on high traffic with frequent re-keys without
3805 problems. Added hmac_receive (and renamed hmac to hmac_send)
3806 in SilcClientConnection in lib/silcclient/client.h and
3807 in SilcIDListData in silcd/idlist.h. Also, removed the
3808 SilcPacketParserContext's cipher and hmac fields as they are
3809 not needed anymore and actually caused some problems when
3810 the ciphers and hmac's changed underneath the packet parser.
3812 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3814 * If re-key protocol is active then process the incoming packets
3815 synchronously since we must assure that icoming packets encrypted
3816 with the old key is processed before the new keys is set to
3817 use. This is true other packets than for REKEY packets.
3818 Affected file silcd/server.c. The same was done to client library
3819 as well, affected file lib/silcclient/client.c.
3821 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3823 * Fixed bug in client and server to accept the force send if
3824 the packet is send from silc_[server/client]_packet_process
3825 function. Otherwise the packets are never delivered, oops.
3827 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3829 * Disable force sending of packets when REKEY protocol is active.
3830 We must assure that no packet is sent directly when rekey is
3831 performed. All packets must be sent through packet queue.
3832 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3833 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3834 function is silc_[server/client]_packet_send_real to check
3837 * Replaced the SIM paths from example config files to
3838 /usr/local/modules. Also, make install creates now
3839 /usr/local/silc/logs directory to hold all the SILC server
3842 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3844 * Made the configure.in.pre work on Solaris. Patch by salo.
3846 * Made all ciphers compatible with non-x86 machines. Defined
3847 CBC mode macros into lib/silccrypt/ciphers_def.h.
3849 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3851 * Fixed the make install.
3853 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3855 * When MAC computation fails the silc_packet_decrypt returned 0
3856 even though it was supposed to return -1. Fixed this. The
3857 affected file is lib/silccore/silcpacket.c.
3859 * Do not replace the config files in /etc/silc (in make install)
3860 if they already exist. Affected file ./Makefile.am.
3862 * Do not send re-key packets immediately but through packet queue.
3863 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3865 * Changed silc_net_check_host_by_sock to return FALSE if the
3866 IP/DNS could not be resolved. Though, it returns the IP address
3867 now even if it could not resolve it (but returns also FALSE).
3868 Affected file lib/silcutil/silcnet.[ch].
3870 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3872 * Added silc_pkcs_decode_identifier to decode the public key's
3873 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3874 Added also silc_pkcs_free_identifier. Added also new context
3875 SilcPublicKeyIdentifier.
3877 * Added -S option to the silc client. It is used to dump the
3878 contents of the specified public key file.
3880 * Changed the PKCS api to return the public key length when
3881 setting the public key.
3883 * Fixed a fatal bug in the public and private key file loading.
3884 Affected file lib/silccrypt/silcpkcs.c.
3886 * Execute the packet parsing for client with zero (0) timeout
3887 if the protocol is active. Affected file silcd/server.c.
3889 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3891 * Made the key generation options to the silcd program. Added
3892 -C option, equivalent to client's option.
3894 * Added new [ServerKeys] config section to the server. It
3895 configures the server's public and private key.
3897 * Defined generic Public Key Payload into the protocol
3898 specification to send specific type of public keys and
3901 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3902 public key or certificate.
3904 * Implemented the GETKEY command to the server and to the
3905 client library and on user interface.
3907 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3909 * Made preliminary `make install' work.
3911 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3913 * Added SilcServerRekey context into silcd/idlist.h.
3915 * Added the PFS support as defined in the specification to the
3916 SKE protocol. Affected files lib/silcske/*.c.
3918 * Added `ske_group' field to the SilcServerRekey context to hold
3919 the number of the SKE group that is used with PFS in re-key.
3920 Affected file silcd/idlist.h.
3922 * Added PFS re-key support to the server. Affected file is
3925 * Added silc_protocol_cancel to cancel execution of the next
3926 state of the protocol. Affected file is
3927 lib/silccore/silcprotocol.[ch].
3929 * Added the re-key support with and without PFS to the client
3930 library. Re-key is performed once in an hour, by default.
3932 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3933 Added silc_client_rekey_callback and silc_client_rekey_final.
3934 Affected files are lib/silcclient/protocol.[ch] and
3935 lib/silcclient/client.[ch].
3937 * Removed the `hmac_key' and `hmac_key_len' fields from the
3938 SilcClientConnection structure; not needed. Affected file is
3939 lib/silcclient/client.h.
3943 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3945 * Do not ask whether user wants to use the negotiated private key
3946 for private messages, just use it. Affected file is
3947 silc/local_command.c.
3949 * Added `send_enc_key' and `enc_key_len' fields to the
3950 SilcIDListData structure since they are needed in the re-key
3951 phase. Affected file is silcd/idlist.[ch].
3953 * Implemented the simple re-key protocol into the server.
3954 Affected files silcd/server.c and silcd/protocol.[ch]. The
3955 re-key will be performed once in an hour, by default.
3957 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3958 Added silc_server_rekey, silc_server_rekey_callback and
3959 silc_server_rekey_final.
3961 * Removed Tunneled flag from the protocol. Updated the code
3962 and the specifications.
3964 * Adde `pfs' field to the SilcIDListData to indicate whether
3965 the PFS is to be performed in the re-key. Affected file is
3968 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3970 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3971 int64 of at least the xintXX size. If void * is less that 4
3972 bytes uint32 * will be used. Defined bool as boolean.
3974 * Changed _ALL_ unsigned long and unsigned int to uint32,
3975 unsgined short to uint16 in the source tree.
3977 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3978 not handle clients that has entry->data.registered == FALSE.
3979 They are not in the network anymore. Affected file is
3982 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3984 * Implemented the sending of the SERVER_SIGNOFF notify in the
3985 server. Affected file is silcd/server.c.
3987 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3988 Added also silc_notify_payload_encode_args into the
3989 lib/silccore/silcnotify.[ch].
3991 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3992 Affected file silcd/packet_receive.c.
3994 * Implemented the SERVER_SIGNOFF notify handling in the client
3995 library. Affected file lib/silcclient/client_notify.c. Also,
3996 implemnted the printing of the SERVER_SIGNOFF info to the
3997 application. Affected file silc/client_ops.c.
3999 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4000 if the deleting was successful. Affected file silcd/idlist.[ch].
4002 * Added support for public key authentication in the connection
4003 authentication protocol in the client library. Affected file
4004 lib/silcclient/protocol.c.
4006 * Changed the server's silc_idlist_get_clients_by_* interface
4007 to support already allocated array so that new entries may be
4008 added to pre-allocated array. Affected file silcd/idlist.[ch].
4009 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4010 and command replies.
4012 * All command reply functions in the server now calls the
4013 pending command callback even if error occured. This way the
4014 error will be delivered to the client as well. Affected files
4015 silcd/command.c and silcd/command_reply.c.
4017 * Fixed INFO command to return local server's info if no server
4018 was provided. Affected file lib/silcclient/command.c.
4020 * Removed RESTART command for good. Updated the code and the
4023 * Rewrote parts of the task system. It is a bit simpler now.
4024 Removed unsued task priorities. The affected files are
4025 lib/silcutil/silctask.[ch].
4027 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4029 * Moved the USERS printing from the library to the application.
4030 Affected files lib/silcclient/command.c and silc/client_ops.c.
4032 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4036 * Added channel key re-key support. The re-key is perfomed
4037 only by the router and is done once in an hour. Added `rekey'
4038 field to the SilcChannelEntry in the server. Affected files
4039 silcd/server.c and silcd/idlist.h.
4041 * Added silc_task_unregister_by_context into the file
4042 lib/silcutil/silctask.[ch].
4044 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4046 * Added SILC_UMODE_GONE mode to indicate when the client is not
4047 present in the SILC network. Added also support to the local
4048 command AWAY that will set this mode. Added support of showing
4049 "xxx is gone" in WHOIS command. The USERS command shows the
4050 gone status as well.
4052 * Fixed setting server and router operator privileges in the
4053 server's UMODE command. Affected file silcd/command.c.
4055 * Merged the SKE KE1 and KE2 payloads into one payload. The
4056 new KE payload is equivalent to the old KE2 payload.
4058 Cleaned up the SKE Start Payload parsing. It now uses the
4059 simple buffer unformatting to do the parsing. A lot faster
4062 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4063 to the SKE that is used to indicate whether both of the SKE
4064 parties should perform authentication. By default only the
4065 responder performs authentication. By setting this flag also
4066 the initiator must do authentication. By default it is unset
4067 since in normal SKE case, client to server connection, only
4068 the responder should do authentication. When doing SKE between
4069 two clients both should perform authentication. Updated the
4070 code and the protocol specs.
4072 * A little fix to IDENTIFY command in the server. Search the
4073 client first by hash not nickname. Affected file is
4076 * Fixed the silc_client_close_connection to support closing
4077 the client to client connections wihtout deleting too much
4078 data. Affected file lib/silcclient/client.c.
4080 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4081 are received if protocol used to be active but is not anymore
4082 the application would crash due to NULL pointer dereference.
4083 Affected files silcd/server.c and lib/silcclient/client.c.
4085 * Added `hash' field to the SilcClientConnection to include
4086 the hash function negotiated in the SKE protocol.
4088 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4089 to set the channel founder authentication data. A client can
4090 claim the founder rights later by providing the authentication
4091 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4092 This way the channel founder can regain the channel founder
4093 privileges even it is left the channel. This works only on
4094 local server and the client must be connected to the same
4095 server to be able to regain the founder rights. Updated the
4096 protocol specs accordingly.
4098 Added support to the CMODE command in the client to set the
4099 founder auth data. Read the README to see how to set it.
4101 Added support to the CUMODE command to claim the founder
4102 rights. Read the README to see how to do it.
4104 Added support for the founder authentication to the Channel
4105 Entry in the server. Affected file silcd/idlist.h.
4107 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4108 server's CMODE command. Affected file silcd/command.c.
4110 * Added the following new functions into lib/silccore/silcauth.[ch]:
4111 silc_auth_get_method and silc_auth_get_data.
4113 * The server now saves the remote hosts public key to the
4114 SilcIDListData pointer. Affected file silcd/protocol.c.
4116 * The normal server now does not remove the channel entry from
4117 the cache if the founder authentication data is set. It used
4118 to remove it if the founder was the last one on the channel on
4119 the server and left the channel. The auth data is saved and
4120 if the channel is re-joined later the old entry is used with
4121 the old auth data. Affected files silcd/command_reply.c and
4124 * Removed the `pkcs' field from the SilcIDListData structure
4125 in the server; it is not used. Affected file silcd/idlist.h.
4127 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4129 * Fixed packet processing on slow links. Partial packets were
4130 never re-processed because the incoming data buffer was cleared
4131 by the application. Application must not directly clear the
4132 sock->inbuf, the packet processing routines handle it. Fixed
4133 this in client library and in server.
4135 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4137 * Fixed the WHOIS and IDENTIFY send reply function to really
4138 check whether to send list or just one entry. Affected file
4141 * Cleaned up the LEAVE command's channel key distribution. The
4142 affected file silcd/command.c.
4144 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4145 can enforce the channel mode as well. In that case the ID
4146 includes the ID of the server. The code now enforces the
4147 mode change if the router have different mode than the server.
4149 * The notify client operation with CMODE_CHANGE notify can now
4150 return NULL client_entry pointer if the CMODE was not changed
4151 by client. Application must check for this.
4153 * Added <Server ID> argument to INFO command to support server
4154 info fetching by Server ID.
4156 * Added silc_server_announce_get_channel_users to get assembled
4157 packets of channel users of the specified channel. Affected
4158 file silcd/server.[ch].
4160 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4161 was freed underneath the ID Cache.
4163 * Re-announce clients when the server received CHANNEL_CHANGE
4164 notify from the router. Affected file silcd/packet_send.c.
4166 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4169 crashed since it did not handle the fact that there is no cipher
4170 called "3" and didn't check the error condition. Now fixed.
4172 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4173 flag. It can be used to send message requests.
4175 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4177 * Implemented the RESTART command in the client.
4179 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4180 notice type messages. Added notice printing to the user
4183 * The channel keys are not re-generated if the channel's mode
4184 is PRIVKEY, ie private key on the channel exists. Affected
4185 files silcd/server.c and silcd/command.c.
4187 * Fixed a little bug in channel message delivery when channel
4188 private keys are set in the server. Affected file is
4189 silcd/packet_send.c.
4191 * Changed the setting on channel->on_channel = TRUE from the
4192 silc_client_save_channel_key to the JOIN command reply. The
4193 key payload is not received if the private channel key is set.
4194 Affected file lib/silcclient/command_reply.c and the
4195 lib/silcclient/client_channel.c.
4197 * When the CMODE_CHANGE notify is sent and the channel private
4198 key mode is removed the channel key must be re-generated in
4199 other cells as well. Added this support for the router in the
4200 silcd/packet_receive.c.
4202 * Added new local command NOTICE to send notice message on
4203 channel. Affected file silc/local_command.[ch].
4205 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * Added new local command ME to the client. It is used to send
4208 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4209 some action. Affected file silc/local_command.[ch].
4211 * Changed channel_message and private_message client operations
4212 to deliver the message flags to the application. Added also
4213 the `flags' arguments to the silc_client_send_channel_message
4214 and silc_client_send_private_message functions. Affected file
4217 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4219 * Redefined the Private Message Payload to support private message
4220 keys and to support the new private message flags. Updated
4221 the protocol specs. Flags makes it possible to have for example
4222 CTCP style messages.
4224 * Added new type SilcPrivateMessagePayload and defined an API
4225 for it in the lib/silcclient/silcprivate.[ch].
4227 * Tested private message private keys successfully. Tested the
4228 private message key set, unset and list commands with the new
4231 * Redefined the Channel Message Payload to include the channel
4232 message flags (equal with private message flags) to support
4233 for example CTCP style messages.
4235 * Defined some of the message (for channel and private message)
4236 flags. Updated the protocol specs and added the flags to the
4237 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4239 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4241 * Added SilcKeyAgreementStatus type to the key agreement routines
4242 to indicate the current status and error if one occured.
4243 The status types are defined in the lib/silcclient/silcapi.h.
4245 * Added new local command KEY that is used to set and unset private
4246 keys for channels, set and unset private keys for private messages
4247 with remote clients and to send key agreement requests and
4248 negotiate the key agreement protocol with remote client. The
4249 key agreement is supported only to negotiate private message keys,
4250 it currently cannot be used to negotiate private keys for channels,
4251 as it is not convenient for that purpose.
4253 * Fixed a minor pending callback setting bug in the function
4254 silc_client_get_client_by_id_resolve, now the function works.
4255 Affected file lib/silcclient/idlist.c.
4257 * Added function silc_net_get_local_port to get local bound
4258 port by socket. Added to lib/silcutil/silcnet.[ch].
4260 * Added `sockets' and `sockets_count' fields to the SilcClient
4261 object. They hold the sockets of the listenning sockets in
4262 the client. Listenning sockets may be for example the key
4263 agreement server. Affected file lib/silcclient/client.[ch].
4264 Added functions the silc_client_add_socket and the
4265 silc_client_del_socket. They are exported to the application
4268 * Added ~./silc/clientkeys to support other client's public keys.
4270 * Renamed verify_server_key client operation to verify_public_key
4271 and added one argument to indicate the type of the connection
4272 (server, client etc.).
4274 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4276 * Added silc_server_connection_auth_request to handle the
4277 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4278 silcd/packet_receive.[ch].
4280 * Added silc_server_send_connection_auth_request into the
4281 silcd/packet_send.c to send the connection auth request packet.
4283 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4286 * Fixed the public key authentication in responder side in the
4287 server. The `auth_data' pointer includes the SilcPublicKey
4288 not the path to the public key. Affected file silcd/protocol.c.
4290 * Implemented the public key authentication in the initiator side
4291 in the server. Affected file silcd/protocol.c.
4293 * Removed the [RedirectClient] config section from the server
4294 configuration. Is not needed and I don't want to implement it.
4296 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4298 * Cleaned up the CMODE command in the server. It now works
4299 correctly and supports all the modes defined in the protocol.
4300 Affected file is silcd/command.c.
4302 * Added `hmac_name' field to the SilcChannelEntry in the server
4303 to hold the default HMAC of the channel. It can be set when
4304 creating the channel (with JOIN command). Affected files
4307 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4308 type to indicate the change of the current cipher and hmac
4309 on the channel. Client can safely ignore the <cipher> argument
4310 (if it chooses to do so) since the CHANNEL_KEY packet will
4311 force the channel key change anyway. The <hmac> argument is
4312 important since the client is responsible of setting the new
4313 HMAC and the hmac key into use.
4315 * Fixed the CMODE command in the client library as well.
4317 * Tested CMODE command in router environment successfully.
4319 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4321 * Show the version of the remote client (or server) when connecting
4322 to the server. It is logged to the log file. Affected file
4323 is silcd/protocol.c.
4325 * Fixed the KILLED notify handling in the client library. The
4326 client must be removed from all channels when receiving the
4329 Also, do not remove the client entry when giving the KILL
4330 command but when the KILLED notify is received.
4332 * Removed silc_idlist_find_client_by_nickname from the server.
4333 Not needed anymore. Affected files silcd/idlist.[ch].
4335 * Implemented the CHANNEL_CHANGE notify type handling to the
4336 server. Affected file silcd/server.c.
4340 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4342 * Added silc_server_send_notify_invite to send the INVITE
4343 notify between routers.
4345 * Implemented the INVITE command correctly to the server.
4347 * Implemented the INVITE notify type handling in the server.
4349 * Implemented the INVITE command to the client library and on the
4352 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4354 * Added function silc_server_get_client_resolve to find the
4355 client entry by ID from all ID lists and then resolve it
4356 (using WHOIS) if it cannot be found. Affected file is
4359 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4361 * Implemented the BAN command to the client library.
4363 * The JOIN command in the server now checks the invite list
4366 * Changed the silc_command_reply_payload_encode_va and the
4367 silc_command_payload_encode_va to support that if argument is
4368 NULL it ignores and checks the next argument. Affected file
4369 lib/silccore/silccommand.c.
4371 * Added silc_server_send_notify_ban to send the BAN notify
4372 type between routers.
4374 * Chaned the silc_notify_payload_encode to support that if
4375 argument is NULL it ignores and checks the next argument.
4376 Affected file lib/silccore/silcnotify.c.
4378 * Tested ban lists in router environment successfully.
4380 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4382 * Implemented BAN command to the server, in silcd/command.[ch].
4384 * Removed the BAN and INVITE_LIST modes from the CMODE command
4387 * Added function silc_string_match to regex match two strings.
4388 Affected files lib/silcutil/silcutil.[ch].
4390 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4392 * Redefined parts of the SilcChannelEntry in the server to support
4393 the new ban and invite lists.
4395 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4397 * Redefined the INVITE command. The same command can be used to
4398 invite individuals to the channel but also to manage the invite
4399 list of the channel (to add to and remove from the invite list).
4400 Updated the protocol specs.
4402 * Added new command SILC_COMMAND_BAN that can be used to manage
4403 the ban list of the channel. Updated the protocol specs.
4405 * Removed the channel modes: the SILC_CMODE_BAN and the
4406 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4407 in the CMODE command. The equivalent features are now available
4408 using INVITE and BAN commands. Updated the protocol specs.
4410 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4411 in the network about change in the current ban list. The notify
4412 type is not used by the client.
4414 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4415 support the invite lists.
4417 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4419 * Added new function silc_string_regexify that converts string
4420 including wildcard characters into regex string that can
4421 be used by the GNU regex library. Added into the file
4422 lib/silcutil/silcutil.[ch].
4424 Added silc_string_regex_combine to combine to regex strings
4425 into one so that they can be used as one regex string by
4426 the GNU regex library. Added into the file
4427 lib/silcutil/silcutil.[ch].
4429 Added silc_string_regex_match to match two strings. It returns
4430 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4432 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4434 * Imported GNU regex to the soruce tree into lib/contrib.
4435 Fixed some compiler warning from the regex.c.
4437 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4439 * Fixed MOTD command in the server to work in router environment.
4441 * Fixed the MOTD command in the client library to support
4442 the server argument in the command.
4444 * Added `nickname_len' argument to the silc_idlist_add_client
4445 in the server, as the `nickname' argument may be binary data
4448 * Added silc_idlist_get_channels to return all channels from
4451 * Implemented LIST command to the server. Affected file is
4454 * Implemented the LIST command to the client library and on the
4457 * Added [<user count>] argument to the LIST command reply.
4458 With private channels the user count is not shown.
4460 * Updated TODO and README.
4462 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * The client entry's data.registered must be TRUE even with
4465 global client entry on global client list. The data.registered
4466 is used to check whether the client is anymore in the network,
4467 for example with WHOWAS command so it must be valid.
4469 * Fixed the WHOWAS command in the server. It now actually works
4470 in router environment. Added function into silcd/command_reply.c
4471 silc_server_command_reply_whowas_save.
4473 * Added silc_idlist_purge function to the silcd/idlist.c
4474 to periodically purge the ID Cache.
4476 * Fixed INFO command in the server. It works now in router
4477 environment. Added <server name> argument to the INFO command
4478 reply. Updated the protocol specs.
4480 * Fixed minor bug in silc_idcache_purge to not purge if the
4481 expire value is zero.
4483 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4484 they were buggy because of the WHOWAS information.
4486 * Fixed local command MSG to handle the async resolving of
4487 the remote client properly. It used to fail the first MSG.
4488 Affected file silc/local_command.c.
4490 * Added `data_len' field to SilcIDCache context.
4492 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Update TODO. Todo in commands in the server.
4496 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4499 used by routers as broadcast packet to inform other routers
4500 about the changed user mode.
4502 Implemented the notify handling in the server. Affected file is
4503 silcd/packet_receive.c. Added the function
4504 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4506 * Added new generic Channel Payload and deprecated the New Channel
4507 Payload. The New Channel Payload is now the generic Channel
4510 * Added new argument `mode' to the silc_server_send_new_channel
4511 as it is required in the Channel Payload now.
4513 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4514 and created a new and real SilChannelPayload to represent the
4515 new generic Channel Payload. Implemented the encode/decode
4516 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4518 * Added silc_server_get_client_channel_list to return the list
4519 of channels the client has joined for WHOIS command reply.
4520 Affected file silcd/server.[ch].
4522 * Implemented the channel list sending in the WHOIS command reply
4523 in server and in the client.
4525 Implemented the channel list displaying on the user interface
4526 as well. Affected file silc/client_ops.c.
4528 * Added silc_channel_payload_parse_list to parse list of Channel
4529 Payloads. It returns SilcDList list of SilcChannelPayloads.
4530 Client for example can use this function to parse the list of
4531 channels it receives in the WHOIS command reply. The caller
4532 must free the list by calling silc_channel_payload_list_free.
4533 Affected files lib/silccore/silcchannel.[ch].
4535 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4537 * Added one new argument <user mode> to the WHOIS command reply
4538 to return the mode of the user in SILC. Updated the protocol
4541 Implemented it to the server and client.
4543 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4545 * Fixed the mode printing on the user interface on joining.
4546 Affected file silc/client_ops.c.
4548 * Implemented the UMODE command and user modes in general to the
4549 client library and to the user interface.
4551 * Implemented the UMODE command to the server.
4553 * The server now sends UNKNOWN_COMMAND error status if client sends
4554 unknown command. Affected file silcd/command.c.
4556 * All server commands now handle the command identifier the right
4557 way when sending the command reply to the client. The client can
4558 use to identify the command replies with the identifier.
4560 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4562 * Added silc_server_get_client_route to resolve the route to
4563 the client indicated by the client ID. Affected file is
4566 * Added silc_server_relay_packet as general function to relay
4567 packet to arbitrary destination. This deprecates functions
4568 like _send_private_message_key, _relay_notify etc. Affected
4569 file is silcd/packet_send.[ch].
4571 Removed silc_server_send_key_agreement,
4572 silc_server_send_private_message_key and
4573 silc_server_packet_relay_notify functions from the file
4574 silcd/packet_send.[ch].
4578 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4579 server. Affected file silcd/packet_receive.[ch].
4581 * Implemented the KILL command to the client. Implemented the
4582 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4583 Affected files lib/silcclient/command[_reply].c and
4584 lib/silcclient/client_notify.c. Implemented the KILL notify
4585 printing in the user inteface.
4587 * Fixed a lot silc_parse_nick memory leaks from the client
4588 library in the file lib/silcclient/command.c.
4590 * Changed the silc_server_send_notify_on_channels's `sender'
4591 argument from SilcSocketConnection to SilcClientEntry to
4592 check the sender as entry and not as connection object and not
4593 to send to the client provided as argument. The affected file
4594 is silcd/packet_send.[ch].
4596 * The notify packets that are destined directly to the client used
4597 to not to be processed by the server. Now changed that and the
4598 server processes all notify packets. After relaying the packet
4599 to the client the notify packet is processed in the server.
4601 * The silc_server_free_client_data now checks whether there is
4602 pending outgoing traffic for the client and purges the data to
4603 the network before removing the client entry.
4605 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4607 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4608 an client is killed from the SILC Network. Updated the protocol
4611 Added new function silc_server_send_notify_killed to the
4612 silcd/packet_send.[ch].
4614 * Added function silc_server_packet_relay_notify to relay notify
4615 packets that are destined directly to a client. In this case
4616 the server does not process the notify packets but merely relays
4617 it to the client. Affected file silcd/packet_send.[ch].
4619 Added also silc_server_packet_process_relay_notify to check
4620 whereto relay the notify. Affected file is
4621 silcd/packet_receive.[ch].
4623 * Implemented the KILL command to the server.
4627 * Added the backup schema desgined last fall to the protocol
4628 specs for everyone to see. The specification is in the
4629 *-spec-xx.txt draft and the packet type definitions for the
4630 backup routers is in *-pp-xx.txt draft. Thusly, added also
4631 new packet type SILC_PACKET_CELL_ROUTERS.
4633 * A big security problem in the implementation discovered. The
4634 signoff of an client did not cause new channel key generation
4635 which it of course should've done. The channel keys must be
4636 always re-generated when client leaves (or signoffs) the channel.
4637 The silc_server_remove_from_channels funtion now handles
4638 the channel key re-generation.
4640 * Added `sender' argument to the silc_server_send_notify_on_channels
4641 to not to send the client provided as argument. Affected file
4642 silcd/packet_send.[ch].
4644 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4646 * Implemented OPER and SILCOPER commands into the server and
4649 * Added silc_auth_verify and silc_auth_verify_data to verify
4650 the authentication directly from the authentication payload.
4651 It supports verifying both passphrase and public key based
4652 authentication. Affected file lib/silccore/silcauth.[ch].
4654 * Added `hash' field to the SilcIDListData structure. It is the
4655 hash negotiated in the SKE protocol. Affected file is
4658 * Slight redesigning of the SilcAuthPayload handling routines.
4659 Do not send SilcPKCS but SilcPublicKey as argument.
4661 * Implemented the public key authentication support to the
4662 serverconfig. The public key is loaded from the provided path
4663 and saved as authentication data to void * pointer. Thus,
4664 changed the unsigned char *auth_data to void *auth_data;
4666 * Fixed SHUTDOWN command to send the reply before the server
4667 is shutdown. :) Affected file silcd/command.c.
4669 * Fixed fatal bug in CONNECT command. The hostname was invalid
4670 memory and server crashed. Affected file silcd/command.c.
4672 * Fixed fatal bug in CLOSE command. The server_entry became
4673 invalid but was referenced later in the command. Affected file
4676 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4678 * Fixed fatal bug in failure packet handling. Server ignored
4679 the failure and thus crashed when it came.
4683 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4685 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4686 that the command may be executed only once in (about) 2 seconds.
4687 The old SILC_CF_LAG flag is same but allows command bursts up
4688 to five before limiting.
4690 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4691 server code. Various commands now includes the CF_LAG_STRICT
4692 flag to disallow any kind of miss-use of the command.
4694 * Fixed the silc_buffer_unformat to not to allocate any data
4695 if the length of the data is zero. It used to allocate the
4696 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4698 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4700 * Changed the format of AdminConnection configuration section
4701 in the server. Added username of the admin to the format.
4702 Affected files silcd/serverconfig.[ch].
4704 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4705 to return admin configuration data by host, username and/or
4708 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4710 * Implemented WHOWAS command to the server. Added the functions:
4712 silc_server_command_whowas_parse,
4713 silc_server_command_whowas_send_reply,
4714 silc_server_command_whowas_from_client and
4715 silc_server_command_whowas_from_server
4717 * Added <Client ID> argument to the WHOWAS command reply. Updated
4718 the protocol specs accordingly.
4720 * Implemented WHOWAS command and command_reply to the client
4723 Implemented the WHOWAS printing on the user interface.
4725 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4727 * Added new argument to the WHOWAS command reply, the real name.
4728 It is an optional argument. Updated the protocol specs.
4730 * Added SilcIDCacheDestructor callback that is registered when
4731 the SilcIDCache is allocated. The callback is called when
4732 an cache entry in the ID Cache expires, or is purged from the
4733 cache. Added into lib/silccore/idcache.[ch].
4735 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4736 to destruct the client entries when the cache entry expires.
4737 Other ID Cache's in server and in the client library ignores
4740 * If the ID Cache entry's `expire' field is zero then the entry
4741 never expires. Added boolean `expire' argument to the
4742 silc_idcache_add function in the lib/silccore/idcache.[ch].
4743 If it is TRUE the default expiry value is used.
4745 * Added silc_server_free_client_data_timeout that is registered
4746 when client disconnects. By default for 5 minutes we preserve
4747 the client entry for history - for WHOWAS command.
4749 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4751 * Added support to the server to enforce that commands are not
4752 executed more than once in 2 seconds. If server receives
4753 commands from client more frequently, timeout is registered
4754 to process the commands. Affected file silcd/command.c.
4755 Added new function silc_server_command_process_timeout.
4757 * Changed NICK_NOTIFY handling in client library to check that
4758 if the client's nickname was changed, so there is no need to
4759 resolve anything from the server.
4761 * Removed error printing from the WHOIS and IDENTIFY commands.
4762 If error occurs then it is ignored silently in the client library.
4763 The application, however, may map the received error to
4764 human readable error string. The application currently maps
4765 the NO_SUCH_NICKNAME error to string.
4767 * Made the command status message public to the application. Moved
4768 them from lib/silcclient/command_reply.c to
4769 lib/silcclient/command_reply.h. The application can map the
4770 received command status to the string with the
4771 silc_client_command_status_message function.
4773 * Added check to the server to check that client's ID is same
4774 as the Source ID in the packet the client sent. They must
4777 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Added dist-bzip hook to the Makefile.am to make bzip2
4780 compressed distributions.
4782 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4784 * Server now enforces the maximum length for the nickname and
4785 the channel as protocol specification dictates. 128 bytes for
4786 nickname and 256 bytes for channel name.
4788 * Moved the WHOIS printing to the application. The client libary
4789 does not print out the WHOIS information anymore, the application
4790 must do it. Renamed silc_client_command_reply_whois_print to
4791 the silc_client_command_reply_whois_save.
4793 The client's idle time is also sent to the application now, and
4794 the idle is shown on screen.
4796 * Added silc_client_command_reply_identify_save to save the
4797 received IDENTIFY entries.
4799 * Do not check for channel private keys in message sending and
4800 reception if the channel does not have the PRIVKEY mode set.
4801 Affected file lib/silclient/client_channel.c.
4803 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4805 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4806 just surfaced after chaning the JOIN procedure.
4808 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4810 * Added silc_client_get_clients_by_list to get client entries
4811 from Client ID list, that is returned for example by JOIN
4812 and USERS command replies. The application should use this
4813 function for example when JOIN command reply is received to
4814 resolve the clients already on the channel (library does not
4815 do that anymore as USERS command reply is not used in the JOIN
4816 procedure anymore). Affected files lib/silcclient/silcapi.h and
4817 lib/silcclient/idlist.c.
4819 * JOIN command reply and USERS command reply returns now SilcBuffer
4820 pointers instead of unsigned char pointers when returning
4821 the client list and mode list.
4823 * Added <Client ID> argument to the JOIN command reply, mainly
4824 for the server to identify for which client the command was
4825 originally sent. Updated protocol specs accordingly.
4827 * Added SilcDlist private_key pointer to the SilcChannelEntry
4828 in the client to support the channel private keys. Affected
4829 file is lib/silcclient/idlist.h.
4831 * Added SilcChannelPrivateKey argument to the function
4832 silc_client_send_channel_message so that application can choose
4833 to use specific private ke if it wants to. If it is not provided,
4834 the normal channel key is used, unless private keys are set.
4835 In this case the first (key that was added first) is used
4836 as the encryption key.
4838 * Implemented the support for channel private key handling.
4839 Implemented the following functions:
4841 silc_client_add_channel_private_key,
4842 silc_client_del_channel_private_keys,
4843 silc_client_del_channel_private_key,
4844 silc_client_list_channel_private_keys and
4845 silc_client_free_channel_private_keys
4847 Affected file lib/silcclient/client_channel.c.
4849 * Added the support for the private keys in the channel message
4850 sending and encryption and in the message reception and
4851 decryption. Affected funtions are
4852 silc_client_send_channel_message and silc_client_channel_message.
4854 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4856 * Added SKE's key verify callback to the client library's
4857 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4859 * Removed the statement that server (or router) must send USERS
4860 command reply when joining to the channel so that the client
4861 knows who are on the channel. Instead, the client list and
4862 client's mode list is now sent in the JOIN command reply to the
4863 client who joined channel. This is better solution.
4865 * Added function silc_server_get_users_on_channel and function
4866 silc_server_save_users_on_channel to the silcd/server.[ch].
4868 * Removed function silc_server_command_send_users from the
4871 * Do not show topic on the client library anymore. The topic is
4872 sent in the command reply notify to the application and the
4873 application must show the topic now.
4875 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4877 * Added client searching by nickname hash into the IDENTIFY and
4878 WHOIS commands in the server as they were clearly missing from
4879 them. Affected file is silcd/command.c.
4881 * Fixed a bug in private message receiving in the client library.
4882 The remote ID was freed and it wasn't supposed, now it is
4885 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4887 * Minor fix to the channel payload; allocate the data area, as it
4888 needs to be of specific length.
4890 * If the key agreement port is zero then the operating
4891 system will define the bound port. Affected files are
4892 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4894 * Added new function silc_channel_payload_decrypt into the file
4895 lib/silccore/silcchannel.[ch].
4897 * Moved the channel message etc, check from silc_packet_decrypt
4898 to applications. The library calls now a generic
4899 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4900 when the packet is either normal or special. This was done to
4901 allow more wide range of checking that was not allowed when
4902 the code was in library. Now applications can do virtually any
4903 checks to the packet and return to the library the decision how
4904 the packet should be processed. Affected files are
4905 lib/silccore/silcpacket.[ch].
4907 Added silc_server_packet_decrypt_check to the server and
4908 silc_client_packet_decrypt_check to the client library.
4910 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4911 to send with specified source and destination information.
4913 * Channel message delivery between routers was broken after the
4914 channel key distribution was fixed earlier. The channel key
4915 was used be to distributed to other routers as well which is not
4916 allowed by the protocol. Now this is fixed and channel keys
4917 really are cell specific and the channel message delivery between
4918 routers comply with the protocol specification.
4920 * Fixed various commands in server to check also the global list
4921 for the channel entry and not just the local list. The affected
4922 file silcd/command.c.
4924 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4926 * Added assert()s to buffer formatting and unformatting routines
4927 to assert (if --enable-debug) when error occurs. Affected
4928 file: lib/silcutil/silcbuffmt.c.
4930 * Changed to auto-reconnect to check whether the remote host is
4931 router and register the re-connect timeout if it is. It used
4932 to check that whether we are normal server, but router must do
4933 auto-reconnect with another router as well. Affected file
4936 * Removed the [<key len>] option from CMODE command as the cipher
4937 name decides the key length, nowadays. See the defined ciphers
4938 from the protocol specification.
4940 * Added [<hmac>] option to the CMODE command to define the HMAC
4941 for the channel. Added SILC_CMODE_HMAC channel mode.
4943 * Added [<hmac>] option for the JOIN command so that user can
4944 select which HMAC is used to compute the MACs of the channel
4947 * Added Hmac field to the Channel Message Payload. The integrity
4948 of plaintext channel messages are now protected by computing
4949 MAC of the message and attaching the MAC to the payload. The
4950 MAC is encrypted. Now, it is clear that this causes some
4951 overhead to the size of the packet but rationale for this is that
4952 now the receiver can verify whether the channel message decrypted
4953 correctly and also when private keys are set for the channel the
4954 receiver can decrypt the packet with several keys and check from
4955 the MAC which key decrypted the message correctly.
4957 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4958 lib/silccrypt/silccipher.[ch].
4960 * Added silc_hash_len to return the digest length into the
4961 lib/silcrypt/silchash.[ch].
4963 * Rewrote parts of Silc Channel Payload interface in the
4964 lib/silccore/silcchannel.[ch]. The encode function now also
4965 encrypts the packet and parse function decrypts it.
4967 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4969 * Fixed a minor formatting bug in the SKE's key material processing.
4970 It actually might have processed the keys wrong way resulting
4973 * Redefined the mandatory HMAC algorithms and added new algorithms.
4974 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4975 and hmac-md5 truncated to 96 bits. The mandatory is now
4976 hmac-sha1-96. Rest are optional (including the one that used
4977 to be mandatory). Rationale for this is that the truncated HMAC
4978 length is sufficient from security point of view and can actually
4979 make the attack against the HMAC harder. Also, the truncated
4980 HMAC causes less overhead to the packets. See the RFC2104 for
4983 * Added new [hmac] configuration section. The SKE used to use
4984 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4985 is of course wrong. The official names that must be proposed in
4986 the SKE are the ones defined in the protocol specification
4987 (hmac-sha1-96 for example). The user can configure any hmac
4988 using any hash function configured in the [hash] section. At
4989 least, the mandatory must be configured.
4991 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4993 * Added HMAC list to the SKE proposal list. It has now both
4994 hash algorithm list and HMAC list. This makes the protocol
4995 incompatible with previous versions. The SKE now seems to work
4996 the way it is supposed to work, for the first time actually.
4998 * Defined plain Hash algorithms to the protocol specification.
5001 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5003 * Implemented support for key agreement packets into the server.
5004 Added functions silc_server_key_agreement and
5005 silc_server_send_key_agreement. Other than these functions,
5006 server has nothing to do with this packet.
5008 * Added support for private message key packets into the server.
5009 Added functions silc_server_private_message_key and
5010 silc_server_send_private_message_key.
5014 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5015 called in the protocol's final callback instead in the END
5016 protocol state. This makes a little more sense and in the same
5017 time in client we can use the same protocol routines for normal
5018 key exchange and to key agreement packet handling as well.
5020 * Added to both client's and server's KE protocol context the
5021 SilcSKEKeyMaterial pointer to save the key material. We will
5022 bring the key material to the protocol's final callback by doing
5023 this. The final callback must free the key material.
5025 * Added SKE's packet_send callback into client's KE protocol
5026 context so that the caller can choose what packet sending function
5027 is used. This way we can use different packet sending when
5028 doing normal SKE when doing key agreement packet handling (in
5029 the key agreement packet handling we do not want to encrypt
5032 * Implemented the responder side of the key agreement routines
5033 in the client. The client can now bind to specified port and
5034 accept incoming key negotiation. The key material is passed
5035 to the application after the protocol is over.
5037 * Implemented the processing of incoming Key Agreement packet
5038 in the client. Added function silc_client_key_agreement to
5041 * Implemented the intiator side of the key agreement routines
5042 in the client. The client can now initiate key agreement with
5043 another remote client. The key material is passed to the
5044 application after the protocol is over.
5046 * Created client_keyagr.c to include all the key agreement
5049 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5050 SILC_TASK_CALLBACK except that it is not static.
5052 * Created client_notify.c and moved the Notify packet handling
5053 from the client.[ch] into that file.
5055 * Created client_prvmsg.c and moved all private message and
5056 private message key routines from the client.[ch] into that file.
5058 * Create client_channel.c and moved all channel message and
5059 channel private key routines from the client.[ch] into that file.
5061 * Changed silc_client_get_client_by_id_resolve to resolve with
5062 WHOIS command instead of IDENTIFY command, in the file
5063 lib/silclient/idlist.c.
5065 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5067 * Implemented the SKE's responder side to the Client library.
5069 * When FAILURE is received to the protocol do not trust it
5070 blindly. Register a timeout to wait whether the remote closes
5071 the connection as it should do it, only after that process the
5072 actual failure. This was changed to both client and server.
5074 * Added client_internal.h to include some of the structures
5075 there instead of client.h in lib/silcclient/.
5077 * Added function silc_task_unregister_by_callback to unregister
5078 timeouts by the callback function.
5080 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5082 * Some "Incomplete WHOIS info" errors has been appearing on the
5083 log files. Took away the entry->userinfo check from WHOIS
5084 reply sending. The entry->userinfo is now " " if client did not
5085 provide one. I thought this was fixed earlier but something
5086 is wrong still. Let's see if the error still appears.
5088 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5090 * Fixed a minor bug in the login when the channel key is
5091 re-generated in the server. It used to generate the key in
5092 wrong order and thus caused problems in the channel traffic.
5094 * Fixed a minor bug in channel key distsribution after
5095 KICK command. The key was not sent to the router even though
5098 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5100 * Added silc_ske_process_key_material_data as generic routine
5101 to process any key material as the SILC protocol dictates. The
5102 function is used by the actual SKE library but can be used by
5103 applications as well. This relates to the private message keys
5104 and the channel private keys since they must be processed the
5105 same way the normal SILC session keys. The protocol dictates
5106 this. Affected files: lib/silcske/silcske.[ch].
5108 Added also silc_ske_free_key_material to free the
5109 SilcSKEKeyMaterial structure.
5111 * Defined silc_cipher_set_key function to set the key for
5112 cipher without using the object's method function. The affected
5113 files: lib/silccrypt/silccipher.[ch].
5115 * Implemented silc silc_client_add_private_message_key,
5116 silc_client_add_private_message_key_ske,
5117 silc_client_del_private_message_key,
5118 silc_client_list_private_message_keys and
5119 silc_client_free_private_message_keys functions in the
5122 Added functions silc_client_send_private_message_key to send
5123 the Private Message Key payload and silc_client_private_message_key
5124 to handle incoming Private Message Key payload.
5126 * Added Cipher field to the Private Message Key payload to set
5127 the cipher to be used. If ignored, the default cipher defined
5128 in the SILC protocol (aes-256-cbc) is used.
5130 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5132 * Removed lib/silcclient/ops.h file.
5134 Redefined parts of the SILC Client Library API. Created new
5135 file silcapi.h that deprecates the ops.h file and defines the
5136 published Client Library API. Defined also private message key
5137 API and channel private key API into the file.
5139 This is the file that the application must include from the
5140 SILC Client Library. Other files need not be included by
5141 the application anymore.
5143 * Added new key_agreement client operation callback and also
5144 defined the Key Agreement library API for the application.
5146 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5148 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5149 is used by clients to request key negotiation between another
5150 client in the SILC network. If the negotiation is started it
5151 is performed using the SKE protocol. The result of the
5152 negotiation, the secret key material, can be used for example
5153 as private message key.
5155 Implemented the Key Agreement payload into the files
5156 lib/silccore/silauth.[ch].
5158 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5160 * Redefined ciphers for the SILC protocol. Added some new ciphers
5161 and defined the key lengths for the algorithms. Changed the
5162 code accordingly. The default key length is now 256 bits.
5164 * Fixed SKE key distribution function silc_ske_process_key_material
5165 when the key length is more than 128 bits. The default key
5166 length in SILC is now 256 bits.
5168 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5169 to indicate unsupported algorithm.
5171 * Renamed rijndael.c to aes.c and all functions as well.
5173 * Fixed a long standing channel key setting bug in client library.
5174 Weird that it has never surfaced before.
5176 * Fixed bug in channel deletion. If the entire channel is removed
5177 then it must also delete the references of the channel entry
5178 from the client's channel list as the client's channel entry and
5179 the channel's client entry share same memory.
5181 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5183 * Implemented CONNECT and SHUTDOWN commands in the client.
5185 * Implemented CLOSE command to the client.
5187 * Added the function silc_idlist_find_server_by_name into the
5188 files silcd/idlist.[ch].
5190 Added the function silc_idlist_find_server_by_conn into the
5191 files silcd/idlist.[ch].
5193 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5195 * DIE command was renamed to SHUTDOWN. Updated the both code
5198 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5199 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5201 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5204 * Added function silc_server_create_connection function to create
5205 connection to remote router. My server implementation actually
5206 does not allow router to connect to normal server (it expects
5207 that normal server always initiates the connection to the router)
5208 so the CONNECT command is only good for connecting to another
5211 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5214 or some other client was kicked from the channel.
5216 Implemented the handling of the notify type to both client
5219 Implemented silc_server_send_notify_kicked to send the KICKED
5220 notify. It is used to send it to the server's primary router.
5222 * Implemented the KICK command into server and client.
5224 * Added `query' argument to the silc_idlist_get_client function
5225 to indicate whether to query the client from server or not if
5228 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5229 to indicate that the client is not channel founder.
5233 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5235 * Removed the rng context from SilcPacketContext structure and
5236 changed that the packet routine uses the Global RNG API.
5238 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5240 * Added support for quit message that client can "leave" on the
5241 channel when it quits the SILC. It is ditributed inside the
5242 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5244 Added silc_server_free_client_data that will take the
5245 signoff message as argument.
5247 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5249 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5251 * Updated parts of the protocol specification to keep it up
5254 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5257 payloads in one packet.
5259 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5260 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5261 use now the new List flag.
5263 * Also deprecated the following packet types: REPLACE_ID,
5264 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5266 * Added list support for Notify packet in server.
5268 * Added silc_server_send_notify_channel_change to send the
5269 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5270 the silc_server_send_replace_id.
5272 * Added silc_server_send_notify_nick_change to send the
5273 NICK_CHANGE notify type. Deprecates the function
5274 silc_server_send_replace_id.
5276 * Added silc_server_send_notify_join to send the JOIN notify type.
5277 Deprecates the function silc_server_send_new_channel_user.
5279 * Added silc_server_send_notify_leave to send LEAVE notify type.
5280 Deprecates the function silc_server_send_remove_channel_user.
5282 * Added silc_server_send_notify_cmode and
5283 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5284 types. Deprecates the silc_server_send_set_mode function.
5286 * Added SERVER_SIGNOFF notify type to indicate that server has
5287 quit. This means that all clients on the channel from that
5288 server will drop. This can be also used when netsplit happens.
5290 Deprecated REMOVE_ID packet type since it is not needed anymore
5293 Added silc_server_send_notify_server_signoff to send the
5294 SERVER_SIGNOFF notify type. Deprecates the function
5295 silc_server_send_remove_id.
5297 Added also silc_server_send_notify_signoff to send the
5298 SIGNOFF notify type.
5300 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5301 SILC protocol from this day on. Changed the protocol
5302 specification as well.
5304 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5305 notify type. It is used between routers to notify about
5306 topic changes on a channel.
5308 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5311 * Partly updated the protocol specification to comply with the
5312 changes now made. It is still though a bit outdated.
5314 * The JOIN notify type now takes one extra argument <Channel ID>.
5315 The packet used to be destined to the channel but now the
5316 JOIN type may be sent as list thus it is impossible to
5317 destine it to any specific channel. By adding this argument
5318 it is again possible.
5320 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5322 * Added CREDITS file. The CHANGES and CREDITS file will appear
5323 in the distribution as well.
5325 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5327 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5328 types in the server's silcd/packet_receive.c.
5330 * Implemented CMODE and CUMODE to work in router environment.
5332 * Fixed minor encoding and decoding buglet from the
5333 lib/silccore/silcmode.c.
5335 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5338 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5340 * Changed all SilcConfigServer* and silc_config_server* to
5341 SilcServerConfig* and silc_server_config*, respectively.
5344 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5346 * Associated the ID (client or server ID) to the Authentication
5347 Payload to avoid any possibility of forging. Updated the
5348 protocol specification and the code accordingly.
5350 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5352 * The RSA key length is now save to the RsaKey context in the
5353 key generation process in lib/silccrypt/rsa.c. The key length
5354 is now used to figure out the maximum size of the block allowed
5355 to be encrypted/signed.
5357 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5358 is equivalent to the silc_mp_mp2bin but does not allocate any
5361 * Changed silc_mp_mp2bin API to take length argument. If it is
5362 non-zero then the buffer is allocated that large. If zero, then
5363 the size is approximated using silc_mp_sizeinbase, which however
5366 * Created Global RNG API which is global RNG that application can
5367 initialize. After initializing, any routine anywhere in the
5368 code (including library) can use RNG without allocating a new
5369 RNG object. This was done to allow this sort of use of the
5370 RNG in code that has no chance to allocate RNG object. All
5371 applications currently allocate this and many routines in the
5372 library use this. Affected file lib/silccrypt/silcrng.[ch].
5374 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5375 it to use the Global RNG API.
5377 * Defined Authentication Payload into protocol specification that
5378 is used during SILC session to authenticate entities. It is
5379 used for example by client to authenticate itself to the server
5380 to obtain server operator privileges.
5382 Implemented this payload into the lib/silccore/silcauth.[ch].
5383 Implemented also routines for public key based authentication
5384 as the new protocol specification dictates.
5386 Moved definitions of different authentication methods from
5387 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5389 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5390 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5391 silc_pkcs_verify_with_hash functions into the file
5392 lib/silccrypt/silcpkcs.[ch].
5394 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * The client entry's userinfo pointer must be always valid.
5397 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5398 will fail since it requires the userinfo. Now, the userinfo
5399 is allocated as "" if actual userinfo does not exist. Actually,
5400 it must exist and it is totally Ok to drop client connections
5401 that does not announce the userinfo. However, we will make
5402 this workaround for now.
5404 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5405 to return the remote port by socket.
5407 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5409 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5410 SILC_SERVER_PENDING_EXEC and added an new macro
5411 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5412 data or when error occurs while processing the pending command.
5414 Added new argument `destructor' into silc_server_command_pending
5415 and to the SilcServerCommandPending object. This destructor is
5416 now called after calling the pending callback or if error occurs
5417 immediately. If error occurs the actual pending callback won't
5418 be called at all - only the destructor. The destructor may be
5419 NULL if destructor is not needed.
5421 All this applies for client library code as well. Similar
5422 changes were made there as well for the pending commands.
5424 In the client, the application must now allocate the
5425 SilcClientCommandContext with the silc_client_command_alloc
5428 * Added reference counter to the SilcServerCommandContext. Added
5429 function silc_server_command_alloc and silc_server_command_dup
5432 Same type of functions added to the client library for the same
5435 * Removed the cmd_ident from IDListData away since it is now
5436 global for all connections. It is the command identifier used
5437 in command sending and with pending commands. The affected file
5440 * Added reference counter to the SilcSocketConnection objecet to
5441 indicate the usage count of the object. The object won't be
5442 freed untill the reference counter hits zero. Currently only
5443 server uses this, and client ignores it. The client must be
5444 set to use this too later. The affected files are
5445 lib/silccore/silcsockconn.[ch]. Added also the function
5446 silc_socket_dup to increase the reference counter.
5448 This was mainly added because it is possible that the socket
5449 is removed underneath of pending command or other async
5450 operation. Now it won't be free'd and proper DISCONNECTING
5451 flags, etc. can be set to avoid sending data to connection that
5452 is not valid anymore.
5454 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5455 the connection. After that it sets SILC_SET_DISCONNECTED.
5456 It is, however, possible that the socket data is not still freed.
5457 The silc_server_packet_process now checks that data is not
5458 read or written to connection that is DISCONNECTED. The socket
5459 get's freed when the reference counter hits zero.
5461 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5463 * Changed the client operation API: channel_message operation's
5464 `sender' is now the client entry of the sender, not the nickname
5465 and the `channel' is the channel entry, not the channel name.
5467 In the private_message operation the `sender' is now also the
5468 client entry of the sender not the nickname.
5470 Affected file is lib/silcclient/ops.h and all applications
5471 using the client operations.
5473 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5475 * Moved the calling of ops->connect() from connect_to_server_final
5476 into receive_new_id functin since that is the point when the
5477 client is actually allowed to send traffic to network. The
5478 affected file is lib/silcclient/client.c.
5480 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5483 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5484 (if needs broadcasting) instead of broadcasting the packets one
5485 by one which would make a burst in the network traffic.
5487 * Added `broadcast' argument to the functions in silcd/server.[ch]
5488 silc_server_create_new_channel[_with_id] to indicate whether
5489 to send New Channel packet to primary router.
5491 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5493 * Added new function into the silcd/server.[ch] files:
5494 silc_server_create_new_channel_with_id to create new channel with
5495 already existing Channel ID.
5497 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5498 lib/silccore/silcpacket.h. This packet is used t send list of
5499 Set Mode payloads inside one packet. Server uses this to set
5500 the modes for the channels and clients on those channels, that it
5501 announced to the router when it connected to it. The protocol
5502 specification has been updated accordingly.
5504 * The silc_server_new_channel did not handle the packet coming
5505 from normal server as it normally does not send that. However,
5506 when it announces its channels it does send it. Implemented
5507 the support for that.
5509 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5510 into the file lib/silccore/id.h.
5512 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5514 * Fixed memory leaks in the functions silc_idlist_del_client,
5515 silc_idlist_del_channel and silc_idlist_del_server in the file
5516 silcd/idlist.c. All of those leaked like a sieve.
5518 * Fixed some small memory leaks in the client's function
5519 silc_client_notify_by_server.
5521 * Added functions into silcd/server.c: silc_server_announce_clients,
5522 silc_server_announce_channels and silc_server_announce_server.
5523 These functions are used by normal and router server to announce
5524 to its primary router about clients, channels and servers (when
5525 router) that we own. This is done after we've connected to the
5528 These functions effectively implements the following packet types:
5529 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5530 and SILC_PACKET_NEW_ID_LIST.
5532 * Added new functions into the silcd/packet_receive.[ch]:
5533 silc_server_new_id_list, silc_server_new_channel_list and
5534 silc_server_new_channel_user_list to handle the incoming
5535 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5537 * Added support of changing Channel ID in the function
5538 silc_server_replace_id. If the server that announces a channel
5539 to the router already exists in the router (with same name but
5540 with different Channel ID), router is responsible to send
5541 Replace ID packet to the server and force the server to change
5542 the Channel ID to the one router has.
5544 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5545 client that the Channel ID has been changed by the router. The
5546 normal server sends this to the client. Client must start using
5547 the new Channel ID as the channel's ID.
5549 Implemented handling of this new type into lib/silcclient/client.c
5550 into the function silc_client_notify_by_server.
5552 * Added new function silc_idlist_replace_channel_id into the files
5553 silcd/idlist.[ch] to replace the Channel ID.
5555 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5557 * Call silc_server_command_identify_check always when processing
5558 the IDENTIFY command in silcd/command.c
5560 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5562 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5563 send keepalive packets. The packet can be sent by clients,
5564 servers and routers.
5566 Added function silc_socket_set_heartbeat into the file
5567 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5568 If not set, the heartbeat is not performed. The actual
5569 heartbeat is implemented in the low level socket connection
5570 library. However, application is responsible of actually
5573 Added silc_server_send_heartbeat to send the actual heartbeat
5574 packet into silcd/packet_send.[ch]. Server now performs
5575 keepalive with all connections.
5577 * Added silc_task_get_first function into lib/silcutil/silctask.c
5578 to return the timeout task with shortest timeout. There was a bug
5579 in task unregistration that caused problems. TODO has been
5580 updated to include that task system must be rewritten.
5582 * The client library will now resolve the client information when
5583 receiving JOIN notify from server for client that we know but
5584 have incomplete information.
5586 * Rewrote parts of silc_server_remove_from_channels and
5587 silc_server_remove_from_one_channel as they did not remove the
5588 channel in some circumstances even though they should've.
5590 * Encryption problem encountered in server:
5592 The LEAVE command used to send the Channel Key packet to the
5593 router immediately after generating it. However, the code
5594 had earlier sent Remove Channel user packet but not immediately,
5595 ie. it was put to queue. The order of packets in the router
5596 was that Channel Key packet was first and Remove Channel User
5597 packet was second, even though they were encrypted in the
5598 reverse order. For this reason, MAC check failed. Now, this
5599 is fixed by not sending the Channel Key packet immediately but
5600 putting it to queue. However, this is more fundamental problem:
5601 packets that are in queue should actually not be encrypted
5602 because packets that are sent immediately gets encrypted
5603 actually with wrong IV (and thus MAC check fails). So, packets
5604 that are in queue should be encrypted when they are sent to
5605 the wire and not when they put to the queue.
5607 However, the problem is that the current system has not been
5608 designed to work that way. Instead, the packet is encrypted
5609 as soon as possible and left to the queue. The queue is then
5610 just purged into wire. There won't be any fixes for this
5611 any time soon. So, the current semantic for packet sending
5614 o If you send packet to remote host and do not force the send
5615 (the packet will be in queue) then all subsequent packets to the
5616 same remote host must also be put to the queue. Only after the
5617 queue has been purged is it safe again to force the packet
5620 o If you send all packets immediately then it safe to send
5621 any of subsequent packets through the queue, however, after
5622 the first packet is put to queue then any subsequent packets
5623 must also be put to the queue.
5625 Follow these rules and everything works fine.
5627 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5629 * Added new function silc_server_remove_clients_by_server to
5630 remove all client entries from ID list when the server connection
5631 is lost. In this case it is also important to invalidate all
5632 client entires as they hold the invalid server entry. This
5633 fixes fatal bug when server has lost connection and will reconnect
5636 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5638 * Made some sanity checks to silc_server_daemonise like to check
5639 whether the requested user and group actually exists.
5641 * Added sanity check to SKE's silc_ske_responder_finish to check
5642 that the public and private key actually is valid.
5644 * Invalidate the client's nickname when receiving Replace ID
5645 packet and the Client ID is being replaced. This means that the
5646 server will query the nickname if someone needs it (client)
5649 * Sort the ID Cache in client library when the ID Cache data
5650 has changed (needs sorting).
5652 * Do not allow for SILC client to create several connections to
5653 several servers. The client does not support windows right now
5654 and generating multiple connections causes weird behaviour.
5656 Irssi-silc client does support windows and can handle several
5657 connections without problems, see: www.irssi.org and SILC plugin.
5659 * Fixed some places where client was added to the IDList. The
5660 rule of thumb is following (in order to get everything right):
5661 If the client is directly connected local client then the
5662 `connection' argument must be set and `router' argument must be
5663 NULL to silc_idlist_add_client function. If the client is not
5664 directly connected client then the `router' argument must
5665 bet set and the `connection' argument must be NULL to the
5666 silc_idlist_add_client function.
5668 * The funtion silc_server_packet_send_local_channel actually did
5669 not check whether the client was locally connected or not. It
5670 does that now. Fixed a bug related to LEAVE command.
5672 * Fixed Remove Channel User payload parsing bug in server's
5673 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5675 * The server's silc_server_save_channel_key now checks also the
5676 global ID list for the channel as it might not be in the local
5677 list. Fixed a bug related to LEAVE command.
5679 * Is this the end of the [<unknown>] buglet that has been lurking
5680 around for a long time? A little for loop fix in server's
5681 silc_server_command_whois_parse that is used by both IDENTIFY
5682 and WHOIS command. At least, this was a clear bug and a cause
5683 of one type of [<unknown>] buglet.
5685 * WHOIS and IDENTIFY commands call the function
5686 silc_server_command_[whois/identify]_check function even if
5687 we are not router server.
5689 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5691 * Added --with-gmp configuration option. If set the GMP
5692 is always compiled in the SILC source tree. If not set then
5693 it is checked whether the system has the GMP3 installed. If
5694 it has then the GMP won't be compiled (the system's headers
5695 and library is used), if it doesn't have it then the GMP is
5696 compiled in the SILC source tree.
5698 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5700 * Changed RSA private exponent generation to what PKCS #1
5701 suggests. We try to find the smallest possible d by doing
5702 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5703 not security fix but optimization.
5705 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5707 * Added new config entry [Identity] to fork the server and run
5708 it as specific user and group. A patch from Bostik.
5710 * Imported Dotconf configuration library into lib/dotconf.
5711 This will be used to create the SILC configuration files later.
5712 It will appear in the distsribution after this commit.
5714 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * A big code auditing weekend happening. Auditing code for
5717 obvious mistakes, bugs and errors. Also, removing any code
5720 Removed files for being obsolete:
5722 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5723 inline in the file lib/silcutil/silcbuffer.h)
5725 o lib/silcutil/silcbufutil.c (the header has inline versions)
5727 Changed code to fix possible error conditions:
5729 o The buffer formatting routines now check that the destination
5730 buffer really has enough space to add the data. This applies for
5731 both buffer formatting and unformatting
5732 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5733 unformatting was changed to accomodate following rules:
5734 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5735 sent to the function while XXX_*STRING will not allocate or copy
5736 the data into the buffer. Instead it sets the pointer from the
5737 buffer into the pointer sent as argument (XXX_*STRING used to
5738 require that the pointer must be allocated already). This change
5739 makes this whole thing a bit more consistent and more optimized
5740 (note that the data returned in the unformatting with XXX_*STRING
5741 must not be freed now). The routines return now -1 on error.
5743 o Tried to find all code that use buffer_format and buffer_unformat
5744 and added return value checking to prevent formatting and
5745 especially unformatting errors and possible subsequent fatal
5748 o Changed ske->x and ske->KEY to mallocated pointers in
5749 lib/silcske/silcske.h. Fixed possible data and memory leak.
5751 o Added return value checking to all *_parse* functions. Fixed
5752 many memory leaks as well.
5754 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5755 so that buffer overflows would not happen. All code now also
5756 checks the return value as it can fail.
5758 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5760 * Added reconnection support to server if the normal server looses
5761 its connection to the router (for example if router is rebooted).
5762 The server performs normal reconnection strategy implemented
5763 to the server. Affected file silcd/server.c.
5765 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5767 * Added new packet type SILC_PACKET_SET_MODE that is used to
5768 distribute the information about changed modes (for clients,
5769 channels and clients channel modes) to all routers in the
5770 network. Updated the protocol specification accordingly.
5772 Added functions into silcd/packet_send.c and
5773 silcd/packet_receive.c: silc_server_send_set_mode,
5774 silc_server_set_mode.
5776 Added new files silcmode.[ch] into lib/silccore that implements
5777 the encoding and decoding of Set Mode Payload. Added new type
5778 SilcSetModePayload. Moved the definitions of different modes
5779 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5781 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5783 * Oops, a little mistake in server's connection authentication
5784 protocol. The protocol is not ended with FAILURE but with
5785 SUCCESS if the authentication is Ok. :) Affected file is
5788 * Implemented NICK_CHANGE notify handling in server in the file
5789 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5790 the local clients on the channel. After the changing nickname
5791 in router environment snhould work and the [<unknown>] nickname
5792 should appear no more.
5794 The silc_server_replace_id function that receives the Replace ID
5795 payload now sends the NICK_CHANGE notify type also in the file
5796 silcd/packet_receive.c
5798 * Changed WHOIS and IDENTIFY command to support the maximum amount
5799 of arguments defined in protocol specs (3328 arguments). This
5800 fixed a bug that caused problems when there were more than three
5803 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5805 * Added extra parameter, command identifier, to the
5806 silc_client_send_command so that explicit command identifier
5809 Changed that ID list routines uses specific command identifier
5810 when sending WHOIS/IDENTIFY requests to the server so that they
5811 can be identified when the reply comes back.
5813 Affected files lib/silcclient/command.[ch],
5814 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5816 * Added `sender' argument to silc_server_packet_send_to_channel
5817 to indicaet the sender who originally sent the packet to us
5818 that we are now re-sending. Ignored if NULL. Affected file
5819 silcd/packet_send.[ch].
5821 * Added some server statistics support in silcd/server_internal.h
5822 SilcServerStatistics structure and around the server code. Also
5823 send some nice statistics information when client is connecting
5826 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * Fixed channel ID decoding in server's JOIN command reply in
5829 silcd/command_reply.c
5831 * Fixed braodcasting of replace ID payload to not to send it if
5832 we are standalone server in silcd/packet_receive.c.
5834 * Fixed all channel message sending routines to not to send
5835 packets to clients that has router set, since they are routed
5836 separately in the same function earlier. Affects file
5837 silcd/packet_send.c and all channel packet sending functions.
5839 * In USERS reply, res_argv[i] are not allocated, the table
5840 is allocated. Thus changed that free the table, not its
5843 * In server's whois_check and identify_check if the client is
5844 locally connected do not send any WHOIS commands - they are not
5847 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * Fixed some minor bugs in client when sending WHOIS command. The
5850 arguments was in wrong order.
5852 * Removed statis function add_to_channel from server in
5853 silcd/command.c that was previously used with the joining but
5856 * Tested USERS command in router environment successfully with two
5857 routers, two servers and two clients.
5859 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5861 * Reorganized the USERS command and command reply in client library
5862 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5863 When the command is given by user we register a pending command
5864 callback that will reprocess the command after the reply has been
5865 received from the server. When reprocessing the packet we then
5866 display the information. Thus, the USERS information is displayed
5867 now in the command callback instead of in the command reply
5868 callback. The processing of the command is same as previously
5869 when server has sent the command reply in the JOINing process.
5871 * Added to USERS command in silcd/command_reply.c to join the client,
5872 we didn't use to know about, to the channel after we've created
5873 a client entry for it. Also, for clienet we did know already still
5874 check whether it is on the channel or not and add it if not.
5876 * Removed silc_server_command_join_notify as the function and its
5879 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5881 * Changed the client's pending command handling to the same as the
5882 server's pending command handling. It is also now possible to
5883 execute command reply functions from other command reply
5884 function as the function callbacks for commands and command
5885 replies are one and same. The pending commands are not static
5886 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5887 in client connection context. Thus, pending commands are server
5888 connection specific as it is convenient.
5890 Changed the function silc_client_command_pending and
5891 silc_client_command_pending_del and added new function
5892 silc_client_command_pending_check. Removed the
5893 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5896 * Added cmd_ident, current command identifier, to the client
5897 connection context in lib/silcclient/client.h to keep track on
5898 command identifiers used in command sending. Client's command reply
5899 function handling now supports the mandatory command identifiers.
5901 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5902 funtions in client to fully support pending command callbacks.
5904 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5905 as one of the arguments to the application in the command reply
5908 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5909 before first releasing SILC but came back. Now it is removed again
5910 and should come back nomore. The FORWARDED flag was used only
5911 by the JOINing procedure by forwarding the command packet to router.
5912 Now, the JOINing procedure has been changed to more generic (due
5913 to various router environment issues) and FORWARDED is not needed
5914 anymore for anything. The protocol specification is yet to be
5917 Now, removed silc_server_packet_forward from server and the flag
5918 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5920 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5922 * Renamed NAMES command to USERS command. The NAMES was named that
5923 due to historical reasons. Now it is renamed. Also, rewrote
5924 parts of the USERS command. The nickname list is not sent anymore
5925 by the server. Only Client ID and mode lists are sent in the USERS
5926 command. Changed this also to the protocol specification.
5928 The client now resolves the names and stuff after it receives
5929 the USERS list from the server when joining to the channel.
5931 * WHOIS and IDENTIFY commands has been changed to support multiple
5932 Client ID's per command. One can now search for multiple users
5933 in the network by sending only one WHOIS or IDENTIFY command.
5934 Changed the code and the protocol specifications.
5936 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5937 uses silc_server_command_whois_parse to parse the request. */
5939 * If normal server, do not parse the WHOIS and IDENTIFY requests
5940 before sending it to the router. Saves some time.
5942 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * Fixed JOIN command on client library. Wrong number of arguments
5945 used to crash the client.
5947 * Added silc_server_channel_has_global function to check whether
5948 channel has global users or not.
5950 * Added silc_server_channel_has_local function to check whether channel
5951 has locally connected clients on the channel.
5953 * The silc_server_remove_from_one_channel now checks whether the
5954 channel has global users or not after given client was removed from
5955 the channel. It also checks whether the channel has local clients
5956 on the channel anymore. If it does not have then the channel entry
5957 is removed as it is not needed anymore.
5959 * The silc_server_notify now checks on JOIN notify whether the joining
5960 client is one of locally connected or global. If it is global then
5961 the channel has now global users on the channel and that is marked
5962 to the channel entry. Also, it now saves the global client to
5963 global list who is joining and JOINs it to the channel. This is
5964 for normal server, that is.
5966 Changed silc_server_send_notify_on_channel,
5967 silc_server_packet_relay_to_channel and
5968 silc_server_packet_send_to_channel check if we are normal server
5969 and client has router set (ie. global client) do not send the
5970 message to that client, as it is already routed to our router.
5972 * Implemented LEAVE notify type handling in silc_server_notify
5975 * Tested LEAVE command in router environment successfully. Tested
5976 with two routers, two servers and two clients.
5980 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5982 * Implemented SIGNOFF notify type handling in silc_server_notify
5985 * silc_server_remove_id now removes the client entry from all channels
5986 it has joined and thusly sends SIGNOFF notify type.
5988 * Rewrote the NAMES list generation in server by removing two excess
5989 loops. The lists are created now inside one loop.
5991 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5993 * silc_server_remove_channel_user checks now also global list
5994 for channel and client.
5996 * silc_server_new_channel_user checks now both local and global
5997 list for channel and client. Fixed a bug in client id decoding.
5998 Used to decode wrong buffer.
6000 * silc_server_channel_message checks now both local and global
6001 list for channel entry.
6003 * Tested channel joining (hence JOIN) in router environment
6004 successfully. Tested with two routers, two servers and two
6007 * Tested channel message sending in router environment successfully.
6009 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6011 * Added silc_server_save_channel_key into server.[ch] to save the
6012 received channel key in Channel Key payload processing. It is
6013 also used in JOIN command reply handling.
6015 Equivalent function silc_client_save_channel_key added into
6016 client.[ch] into client library.
6018 * Changed JOIN command reply to send information whether the channel
6019 was created or not (is existing already) and the channel key
6020 payload. Changed protocol specs accordingly.
6022 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6023 the request was sent by ID and not by nickname. Crashed on
6026 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6028 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6029 now correctly save the received data.
6031 * silc_server_free_sock_user_data now notifies routers in the
6032 network about entities leaving the network.
6034 At the same time implemented functions silc_server_remove_id
6035 and silc_server_send_remove_id to receive and send REMOVE_ID
6036 packets. The packet is used to notify routers in the network
6037 about leaving entities. The ID removed will become invalid in
6040 * Added function silc_idlist_del_server into server. Removes and
6041 free's server entry from ID list.
6043 * silc_server_private_message function now checks, if we are router,
6044 that the destination ID really is valid ID, naturally.
6046 * In router when NEW_ID packet is received (for new client) the
6047 hash of the Client ID is saved in the ID Cache but the
6048 client->nickname is set to NULL, instead of putting the hash
6051 IDENTIFY command now also checks that client->nickname must be
6052 valid. If it is not if will request the data from the server who
6053 owns the client. Added new function
6054 silc_server_command_identify_check.
6056 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6057 to set the command to already allocated Command Payload.
6059 * Tested private message sending in router environment with two
6060 routers, two servers and two clients. Fixed minor bugs and now
6063 * Fixed segfault from client's NAMES command. Used to crash if
6066 * Forwarded packets must not be routed even if it is not destined
6067 to the receiver. Changed server code comply with this.
6069 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6071 * Added `require_reverse_mapping' boolean value to ServerParams
6072 structure. If TRUE (not default) the server will require that
6073 the connecting host has fully qualified domain name.
6075 If the reverse mapping is not required and hostname could not be
6076 found the IP address is used as hostname.
6078 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6080 * Implemented version string checking to both client and server.
6081 The check is incomplete currently due to the abnormal version
6082 strings used in development version of SILC.
6084 * Changed all command functions in server to use the new
6087 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6089 * Changed char *data to unsigned char *data in ID Cache system to
6090 support binary data as ID Cache data. Changed code to support
6091 binary data in lib/silccore/idcache.c.
6093 * Renamed silc_server_packet_relay_command_reply to
6094 silc_server_command_reply as it is normal packet receiving
6095 function. Rewrote the function to accept command replys for
6096 servers and not only for clients.
6098 * Mark remote router always as registered server if we are connecting
6099 to it. Otherwise, commands sent by the router to us are ignored.
6101 * All ID List find routines now returns the ID Cache Entry pointer
6102 as well if requested.
6104 * WHOIS command works now in router environment, tested with two
6105 routers, two servers and two clients.
6107 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6108 in router environment (as it is almost equivalent to WHOIS) but
6109 hasn't been tested thoroughly. Added new functions:
6111 silc_server_command_identify_parse
6112 silc_server_command_identify_send_reply
6113 silc_server_command_identify_from_client
6114 silc_server_command_identify_from_server
6116 * Disabled route cache adding because adding two different ID's with
6117 same IP replaces the old cache entry thus giving wrong route.
6118 The entry->router->connection is always the fastest route anyway
6119 so route cache may not be needed. Of course, new routes maybe
6120 established after receiving the ID when the entry->router->connection
6121 might not be anymore the most optimal.
6123 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6125 * Add route cache for received ID for fast routing.
6127 * Added silc_server_packet_route to route received packet on router
6128 that is not destined to us.
6130 * Renamed silc_server_get_route to silc_server_route_get.
6132 * Added id_string and id_string_len fields into SilcServer to
6133 include encoded ServerID for fast comparing without excess
6134 encoding of the ID's.
6136 * Cleaned up WHOIS command on server side. Added following static
6139 silc_server_command_whois_parse
6140 silc_server_command_whois_check
6141 silc_server_command_whois_send_reply
6142 silc_server_command_whois_from_client
6143 silc_server_command_whois_from_server
6145 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6146 arguments in command replies. All command functions should be
6147 updated to use this macro.
6149 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6151 * Minor typo fixes on command reply handling on server.
6153 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6155 * Added silc_server_command_add_to_channel internal routine to add
6156 the client to the channel after router has created the channel and
6157 sent command reply to the server.
6159 * Added generic silc_server_send_command to send any command from
6162 * Use static buffer with ID rendering instead of duplicating data.
6164 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * Fixed a channel user mode bug when joining to a channel server gave
6167 everybody channel founder rights, oops.
6169 * We mark ourselves as the router of the incoming server connection
6170 if we are router ourselves. This way we can check in some packet
6171 sending functions whether it is locally connected server. For
6172 incoming router connections we put NULL.
6174 * For router sending packets locally means now always sending the
6175 packet cell wide; to local clients and local servers. For normal
6176 server sending packet locally means sending it to only local
6179 * Fixed the JOIN command to really work in router environment. If the
6180 channel is created it is always created by the router. Router is
6181 also responsible of making the initial joining to the channel,
6182 sending JOIN notify to the sending server and distributing
6183 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6184 does not exist server doesn't do anything else but forward the
6185 command to the router which performs everything.
6187 * Added silc_server_send_channel_key function to send the Channel Key
6190 * Added silc_server_create_channel_key to create new channel key. The
6191 channel key is now re-generated everytime someone joins or leaves
6192 a channel, as protocol dictates. Note: channel->key_len is the
6195 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6197 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6198 packet_receive.[ch] to separate packet sending and receiving
6199 routines. The server.[ch] now includes everything else including
6200 actual packet processing (writing and reading data) and other
6203 Renamed silc_server_private_message_send_internal to
6204 silc_server_send_private_message. The routine is still though
6205 used only to relay private messages as server does not send
6206 private messages itself.
6208 Renamed silc_server_new_channel to silc_server_create_new_channel
6209 and added new function sicl_server_new_channel that handles the
6210 incoming New Channel packet. Added also new sending function
6211 silc_server_send_new_channel to send New Channel Payload.
6213 * Added new function silc_server_notify to process incoming notify
6214 packet to the server/router. Server may then relay the notify
6215 to clients if needed.
6217 * Added new function silc_server_new_channel_user to process incoming
6218 New Channel User packet. Router will redistribute the packet and
6219 send JOIN notify to its local clients and locally connected servers
6220 if needed. Normal server will send JOIN notify to its local client
6221 on same channel when received this packet. Added also corresponding
6222 sending function silc_server_send_new_channel_user to sent the
6225 * Added boolean route argument to send_notif_to_channel and
6226 packet_send_to_channel functions to attempt to route the packet
6227 if it is TRUE and send only locally if it is FALSE.
6229 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6231 * silc_server_replace_id now broadcasts the received replace ID
6232 packet if it is not broadcast packet already. The router must
6233 broadcast to inform other routers about changed ID.
6235 * Added backpointer to server's router into SilcServer context in
6236 silcd/server_internal.h.
6238 * Fixed silc_server_packet_broadcast to send correct broadcast
6241 * The channel key is now distributed to the local client as soon
6242 as it is received from the router (in router environment) so that
6243 no other packet may be sent for the channel until client has
6246 * silc_server_remove_channel_user now broadcasts the received
6247 Remove Channel User packet if it is not broadcast packet already.
6248 The router must broadcast to inform other routers about removed
6251 * Added users field into SilcPacketContext that is a reference count
6252 of the context. One can increase the reference count by calling
6253 silc_packet_context_dup which is now changed to just increase the
6254 reference count instead of duplicating the data. The reference
6255 count is decresed by calling silc_packet_context_free that will
6256 free the data after the reference count hits zero.
6258 For now on the packet context and everything allocated into it
6259 (including the raw packet from network) must be freed by calling
6260 the new silc_packet_context_free function. Added also new function
6261 silc_packet_context_alloc that must be used now to allocate the
6262 context. This also means that if a routine is asynchronous from
6263 silc_[client/server]_packet_parse_type the packet context must
6264 be duplicated by calling silc_packet_context_dup. Otherwise it
6265 gets free'd after silc_[client/server]_packet_parse_type returns.
6266 Also, one must remember that if packet is duplicated then its
6267 reference count must be decresed by calling the free function as
6268 many times as it was duplicated.
6270 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6271 from both client and server.
6273 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6275 * Made joining to a channel working in router environment.
6277 * Cleaned up JOIN command on server side and create function
6278 silc_server_command_join_channel internal routine to make the
6281 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6283 * Changed silc_command_pending list to SilcDList. Also, added
6284 `ident' field to SilcServerCommandPending structure to identify
6285 the reply and to call correct callback.
6287 Added silc_server_command_pending_check function to replace the
6288 corresnponding macro. The silc_command_pending list is not
6291 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6292 to set identifier to previously allocated Command Payload. It
6293 is used to set identifier for command when resending Command
6296 * Added silc_command_payload_encode_payload to encode Command
6297 Payload buffer from SilcCommandPayload structure.
6299 * Added silc_argument_payload_encode_payload to encode Argument
6300 payload buffer from SilcArgumentPayload structure.
6302 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6304 * Changed WHOIS command to support router connection on server side.
6305 The whois request is always sent to router unless the server is
6306 standalone server. After server has received the reply from the
6307 router will it send the reply to the client.
6309 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6310 broadcast received broadcast packet. The function is used only
6311 by router. The broadcast packet is always sent to the router's
6314 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6315 render given ID to printable string, for log files for example.
6317 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6319 * Made basic router to router connections working. At least they
6320 can now connect to each other but nothing really works the way
6321 they are supposed - yet.
6323 * Added new initiator token to RouterConnection configuration
6324 file in silcd/serverconfig.[ch]. It is used to tell whether we
6325 are the initiator to the remote router or whether we'll expect
6326 the other end to connect.
6328 * Moved registering of listener task to silc_server_init, hence
6329 the server starts listenning as soon as it is run, even if it
6330 does not have connections to other routers. Let's see how well
6333 * Changed default connection retry timeouts for more suitable in
6336 * Removed cipher and such arguments from silc_idlist_add_client
6337 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6338 Added new function silc_idlist_add_data to add the keys and stuff
6341 * Added SilcIDListData structure and added it to SilcClientEntry
6342 and SilcServerEntry as their first field in the structure. This
6343 way we can explicitly cast the ID entries to the SilcIDListData
6344 structure and get common data for the entries. In past, we had
6345 to first check what type of connection it is and then cast it to
6346 correct ID entry type. Now, we can directly cast the opaque
6347 pointer to the SilcIDListData (no matter what ID entry it actually
6348 is) and get the data needed.
6350 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6352 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6353 in some circumstances even if threre were timeout tasks, though not
6354 IO tasks, but tasks anyway. Now fixed.
6356 * Defined SilcServerConnection structure to hold connection specific
6357 stuff about directly connected servers and routers. The definition
6358 is currently in silcd/server_internal.h. I thought about having
6359 a bit more important role fro this struct but for now it is used
6360 only when connecting to other server (or router actually).
6362 * Added connecting retry support in server when connecting to
6363 router(s). The retry feature implement exponential backoff
6364 algorithm. Also, added SilcServerParams structure to hold default
6365 parameters for server. For now, it include these retry settings
6366 and are hard coded. After server is moded to be as Silc Server
6367 Library this structure will be more important.
6369 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6371 * Changed client librarys channel->clients table to SilcList and
6372 changed code accordingly.
6374 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6376 * Changed client's channel table to SilcList and changed code
6377 accordingly. Also changed SilcChannelClientEntry to include back-
6378 pointer to the channel so that client entry can use that structure
6379 as list as well and we have fast cross-reference to the channel.
6380 This change dramatically decreased the complexity of channel
6381 handling with client entry and vice versa (removed one extra
6382 loop when searching for channel entry from many functions).
6384 * Changed server->sim from table to SilcDList and changed code
6387 * NAMES command can now be used from user interface. It will show
6388 the user list on the channel, neatly.
6390 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6391 Code now saves realname of the user if it becomes available.
6393 * Renamed configure.in to configure.in.pre and made ./prepare
6394 script to automatically add correct version string to
6395 configure.in which it creates from configure.in.pre.
6397 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6399 * NAMES command reply now shows users mode with the nickname when
6402 * Moved silc_client_ch[u]mode[_char] functions from
6403 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6404 place sucks, they are utility functions and should be in some
6407 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6409 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6412 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6416 * Added TRQ (efficient deque and list library) into lib/trq. This is
6417 a very good list library that is currently used in the SILC. Defined
6418 SilcList API over the library because I didn't like the API very
6419 much. See lib/trq/silclist.h for the API and examples of how to
6420 use the API. Fixed various places in the code to use the new
6421 SilcList API. The SilcList is meant for lists that has a structure
6422 already defined as a list. It is not suitable to add just some
6423 context to the list (in TRQ, the context is the list actually).
6425 So, I defined SilcDList that can be used for the purpose where
6426 predefined list structure does not exit. This can be used as
6427 such list. Now some context just can be added to the SilcDList.
6428 Currently this list is not used in the SILC just yet, though there
6429 are a lot places where this can replace dynamically allocated
6430 tables and I will fix these places, later, to use SilcDList.
6431 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6432 and use TRQ internally).
6434 Also fixed some annoying warning messages that the original TRQ
6435 code generated. Also minor changes to TRQ's Makefile.in.
6437 * Added support for querying by Client ID to both WHOIS and
6438 IDENTIFY commands into server, as required by the protocol.
6440 * Removed method function pointers from SilcBuffer structure. They
6441 weren't used to anything and just increased the context size for
6442 no good reason. This change also made silc_buffer_alloc and
6443 silc_buffer_free functions inline functions.
6445 * Disabled command flooding detection support until it's fixed so
6446 that it accepts commands in but does not execute them more than once
6449 * Added silc_net_localhost(), to return local hostname, into
6450 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6451 that must be initialized before calling silc_client_init.
6453 * Added new function: silc_server_send_notify_on_channels to send
6454 notify messages to all channels client has joined. It is assured
6455 that the message is sent only once per client.
6457 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6458 lib/silcutil/silcutil.[ch] as silc_format function. The new
6459 function is generic and is used by server as well, not only by
6460 the logging routines.
6462 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6463 the provided version string was not acceptable. Added new function:
6464 silc_ske_check_version into lib/silcske/silcske.h. The function
6465 must be implemented by the application (client or server) and it
6466 does not reside in the SKE library. The function checks the version
6467 string remote end sent.
6469 * Added back pointers (to opaque context and to SilcSocketConnection)
6470 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6472 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6473 duplicate packet context structure.
6475 * Changed `notify' client operation to send same arguments as client
6476 receives from server except for ID's. ID's are mapped to correct
6477 ID entry and that is returned. Also, if channel entry is not sent
6478 by server but the notify is for channel the channel entry is sent
6479 to application (otherwise application doesn't know that it is for
6480 channel (library gets it from packet's Destination ID)).
6482 * Added silc_client_remove_from_channels into client library to
6483 remove a client from all channels it has joined to. Used when
6484 received SIGNOFF notify from server. Added also new function
6485 silc_client_replace_from_channels to replace old ID entry with
6486 new ID entry on all channels. Used when received NICK_CHANGE
6489 * Fixed ID Cache list handling in silc_idlist_get_client in
6490 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6491 to get (or query) client by ID.
6493 * Updated TODO list.
6495 * Added connection authentication status message defined by the
6496 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6497 support for these into the code in client and server side.
6499 * Added generic function silc_client_send_command to send any command
6500 with variable argument list. Application should use this function
6501 to send commands if the command functions provided by the library
6502 does not suite for the application's user interface needs.
6504 * Added new `failure' client operation. Application is notified about
6505 received failure packet if client is executing a protocol. In this
6506 case the protocol's execution has failed.
6508 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6509 is required by the protocol.
6511 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6512 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6515 * Added status flag to SilcSKE object to indicate realtime status
6516 of the SKE protocol.
6518 * Application receives now exactly same command reply arguments as
6519 the library receives from server. However, if ID is received the
6520 corresponding ID entry is returned to the application (eg. Client
6521 ID is mapped to correct SilcClientEntry entry and that is returned).
6522 Changed command_reply client operation due to this change.
6524 * Changed all ID's in commands and in command replys as ID Payloads.
6525 Change affected both client and server side codes.
6527 All ID's sent in SILC network (with execption of ID's in SILC
6528 Packet header) are sent in ID Payload to support variable length
6531 * Server now notifies nick changes and notifies all clients on
6532 the channels about the new nickname (about the new Client ID,
6535 * Implemented CMODE command to change channel modes. Supports all
6536 channel modes defined by the protocol specs except ban and invite
6537 lists. (Also, private channel key mode is supported but support for
6538 setting private channel key in client is missing, thus, this mode
6539 has no effect on client side (except that server requires that the
6540 client uses private channel key and normal channel traffic does not
6543 Also, invite mode works per se, but INVITE command does not work
6544 yet correctly, so you can set channel as invite only channel but
6545 inviting clients to the channel does not work (it is yet to be
6546 thought what's the best way to do it).
6548 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6549 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6550 Implemented CUMODE command to change user's mode on the channel.
6551 Supports all modes defined by the protocol specs.
6553 * Added NAMES command reply to return users modes on the channel.
6555 * Removed unnecessary and slow ciphers from lib/silccrypt.
6557 * Set SO_KEEPALIVE option to connection sockets by default.
6559 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6561 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6562 redefined the Notify Payload into protocol specs.
6564 * Added silc_id_payload_parse_id to get ID directly from raw
6567 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6569 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6570 accept searching by Client ID as well.
6572 * Added support for LEAVE and SIGNOFF notify types in client library.
6574 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6575 to parse ID Payload from raw data.
6577 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6579 * Added flags parameter into silc_ske_assemble_security_properties
6580 function in lib/silcske/silcske.[ch].
6582 * Changed notify client operation to fit better for notify messages
6583 sent by server. The notify payload received from server is now
6584 passed to the application (after parsing it to SilcNotifyPayload).
6585 It is application's responsibility to retrieve the arguments
6586 from the payload and show the message the way it wants. The message
6587 sent by server is implementation specific.
6589 * Changed public keys to comply with the protocol specification.
6590 Old public keys are not supported anymore and are not compatible.
6592 * Removed nickname from Channel Payload as the latest draft removed
6593 it. The client must resolve the nickname from the NAMES command
6594 reply received when it joined the channel.
6596 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6598 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6600 * Fixed some errors in protocol specification drafts.
6602 * Created lib/silccore/silcnotify.c to implement Notify Payload
6603 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6604 generic payloads described by protocol specifications. The file
6605 includes implementations for ID Payload and Argument Payload.
6607 * Changed Command Payload implementation to use the new Argument
6608 Payload. Changed command_xxxx_payload to command_payload_xxxx
6609 to comply with SILC coding conventions.
6611 * Added suppport for Argument Payload handling in Notify Payload
6612 implementation as protocol requires it. Added the new support
6613 into server and client lib as well.
6615 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6617 * Added support for multiple nicknames on same channel. [n] is
6618 added locally to the nickname if there are more than one same
6619 nicknames on the channel.
6621 * Server now sends all nicknames that matched WHOIS request.
6622 Client also shows the list received from server.
6624 * Added TOPIC command to client side. User can now set and show
6625 current topic on channel.
6627 * Added MOTD command to client and server. Also, server sends the
6628 motd when client connects to the server.
6630 * Changed version strings to comply ISO 8601.
6632 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6634 * Fixed protocol error handling in client library. It should now
6635 cope even if the SKE fails for some reason.
6637 * Made new protocol specification drafts for submitting to IETF.
6639 * Implemented TOPIC command to server in silcd/command.c.
6641 * Added two new notify types into lib/silccore/silcnotify.h:
6642 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6643 notify nickname change and topic setting/change on a channel.
6645 * API change of command_reply operation in client library. The
6646 application gets now the status type received from server as well.
6648 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6650 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6652 * Cras fixed and optimized the packet handling even further and
6653 it should work now. Minor change to the prototype of function
6654 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6656 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6658 * Added new function into lib/silcutil/silcschedule.[ch]:
6659 silc_schedule_with_fd to select() a specified fd. The function
6660 returns after timeout expires or data arrives or goes. The
6661 function is used by packet routines to wait that all data is
6662 received from network.
6664 * Fixed data reading from network in lib/silccore/silcpacket.c.
6665 The code now assures that all data is read from the fd and then
6666 continues packet processing. This was a bug fix since the code
6667 used to drop some data in some circumstances.
6669 * Added new function into lib/silcclient/client.[ch]:
6670 silc_client_start_key_exchange to start key exchange after
6671 connection has been established to server. The code internally
6672 now uses this funtion but its main purpose was to provide it
6673 for applications that perform their own connecting. After
6674 application has created a connection it merely calls this
6675 function to start the key exchange between client and server.
6676 The library takes care of everything else after that.
6678 Updated also lib/silcclient/README to explain the usage of
6681 * Do not send to application information that connection has
6682 been established. Application gets notified it by connect
6685 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6687 * Applied cras's patch to add silc_schedule_one function. The
6688 function runs scheduler once and returns.
6690 * Fixed the scheduler after cras messed it up. The timeout
6691 handling works now as it's supposed to work.
6693 * Added into lib/silccore/ silcnotify.h to include notify
6694 message types support. Changed silc_server_send_notify*
6695 functions, in server.[ch], to support those new notify types.
6696 Added the support for the notify types into client library,
6697 as well. Added new notify client operation into ops.h in
6700 * Changed silc_server_packet_send_to_channel to send normal
6701 packets instead of just channel message packets. The function
6702 is now used to send the notify packets to channels. It is not
6703 used to send channel message packets anymore, as server never
6706 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6707 va_arg()s as it seems to require it nowadays. I guess, if SILC
6708 is compiled with older va_arg() the new code should work anyway.
6710 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6712 * Splitted core library. Core library (lib/silccore) includes
6713 now only SILC protocol specific core (and common) components.
6714 Created new utility library (lib/silcutil) that includes more
6715 generic purpose stuff. The stuff for util library was taken
6716 from the old core library. This was minor and easy split.
6718 * Created SILC Client Library (lib/silcclient) that includes
6719 implementation of the SILC client without user interface. This
6720 was major move from silc/ directory. The code has been changed
6721 so that it is transparent towards the user interface. The
6722 silc/ directory includes now the same user interface as before
6723 and it uses the new client library. Read lib/silcclient/README.
6724 Basicly, the client library performs everything else related
6725 to SILC except user interface handling. Also, configuration
6726 files are considered to be part of user interface and library
6727 does not handle them.
6729 This change also changed a lot of structures, function naming etc.
6730 Most important change was that SilcClientWindow object was
6731 renamed to SilcClientConnection in the client library. Created
6732 also new file lib/silcclient/ops.h. Also added new files
6733 silc/local_command.[ch] and silc/client_ops.[ch].
6735 All these changes were made to make it easier for user interface
6736 designers to create what ever user interface for the SILC client
6739 It is also expected that the server will be moved to lib
6740 directory as well and SILC Server Library will be created;
6741 sometimes in the future.
6743 * Removed Local commands from lib/silccore/silccommand.h as
6744 they are application specific and new client library does not
6745 handle any of those anymore.
6747 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6748 old client implementation in silc/.
6750 * Added support for callback functions in SILC_LOG_* macros.
6751 Application can now set its own callbacks that will be called
6752 instead of using the default functions that will always print
6753 the debug messages to stderr (or stdout). Also, debugging can
6754 now be disabled by setting silc_debug to FALSE and re-enabled by
6755 setting it to TRUE. Note, that logging will still work even
6756 if debugging is disabled.
6758 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6759 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6760 silc_log_reset_debug_callbacks.
6762 * To enable debugging in silc client one must give now -d
6763 option on command line.
6765 * Changed silc_schedule_init to automatically allocate task queues
6766 if they are not allocated before calling it.
6768 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6770 * Added GMP 3.1 into math library.
6772 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6774 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6775 a channel in SILC network. The packet is used by servers and
6776 routers to notify other routers that user has left a channel.
6777 This little feature was missing until now. Added the feature
6778 to protocol specification as well.
6780 Added functions: silc_server_send_remove_channel_user and
6781 silc_server_remove_channel_user into server.[ch].
6783 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6784 lib/silccore/silcpacket.h. However, they are not implemented
6787 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6789 * Fixed joining to a channel and sending channel messages
6790 between server and router. The channel message sending should
6791 now work inside a cell.
6793 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6795 * Fixed the private message sending between server and router.
6796 The private message sending should now work inside a cell.
6798 * Added silc_server_replace_id into server.[ch] to replace
6799 existing ID in the SILC network.
6801 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6802 and silc_idlist_replace_server_id into idlist.[ch] in server.
6804 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6806 * Fixed the server to server connections. Server can again now
6807 connect to router. Router to router connections probably does
6810 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6812 * Added dynamic protocol registering support. Now protocols can
6813 registered and unregistered on the fly. Patch by cras.
6815 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6817 * Added lib/contrib directory to hold routines that some platforms
6818 don't have but are needed by SILC.
6820 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6821 into lin/contrib to provide getopt() and getopt_long() for
6822 those who don't have it.
6824 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6826 * Added AWAY command to client. When away message is set and
6827 client receives a private message packet the client automatically
6828 replies to the sender with the away message.
6830 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6831 bug seemed to be the cause of recent problems when compiling
6834 * Added version detection support to SKE protocol specification
6835 and added the new changes to the SKE implementation as well.
6836 There were other minor changes in the SKE protocol as well.
6838 Many changes in lib/silcske/silcske.[ch] and in
6839 lib/silcske/payload.[ch].
6841 * Added ^U functionality, clear input line. Patch from cras.
6843 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6845 * Mainly small bugfixes on core library. Fixed some debugging
6846 logging and buffer overflow in silclog.c.
6848 * Updated config.sub and config.guess on the distribution tree.
6850 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6852 * Added command lagging support in server. Client may execute
6853 commands now only once in two seconds.
6855 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6857 * Optimized packet reception. MAC computation and checking is now
6858 also more optimized. A lot previously duplicated code is now
6859 used as generic by both client and server.
6861 * Fixed key pair generation in clientutil.c
6863 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6865 * Added into lib/silccore/silcbufutil.[ch] new function;
6866 silc_buffer_realloc.
6868 * Moved generic packet sending/encryption functions to
6869 lib/silccore/silcpacket.[ch] from client and server. Some
6870 rewriting of the functions.
6872 * Moved all generic packet reception/decryption functions to
6873 lib/silccore/silcpacket.[ch] from client and server. The
6874 packet processing is now much cleaner in both client and server.
6875 These were major changes in both client and server.
6877 * Created many common functions in server to do packet sending.
6878 Previously code were duplicated a lot, this has been removed
6881 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6883 * Rewrote major parts of the ID cache system. Don't know
6884 whether it is better now or not but at least the API is more
6887 * Major rewrite on ID cache stuff on client because of the ID
6888 cache API changes. Added idlist.c to client.
6890 * Also major rewrite on ID cache stuff on server as well.
6891 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6892 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6893 in hand, instead they are all put into the ID cache system now.
6894 All server_idlist_* routines uses ID cache now instead of
6895 traversing its own lists (those lists does not exist anymore).
6896 SilcIDList though still exists. Also, SilcXXXEntry's are
6899 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6901 * Finally made the SKE implementation compliant to the protocol
6902 specification. All mp integers are now binary encoded as
6903 opposed being HEX encoded.
6905 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6908 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6909 functions: silc_[encode/decode]_pem. Also added function
6910 silc_encode_pem_file to PEM encode with newlines ('\n') for
6913 * SILC public keys are now encoded either PEM or binary. Same
6914 option is for private keys as well. By default private keys
6915 are binary encoded and public keys PEM encoded. Silly HEX
6916 encoding were removed.
6918 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6919 function to create fingerprints.
6921 * Fixed a bug in SHA1; does not change the original data anymore.
6923 * Partly implemented INFO command on client and server side.
6924 Fixed CLEAR command. Changes to SERVER command; show current
6925 server(s) when giving command without arguments. Added
6926 VERSION command to client.
6928 * Added check to server that unregistered connections cannot
6929 execute commands (unless it is specificly allowed).
6931 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6933 * Fixed screen refresh.
6935 * Fixed channel joining bug from client. On some circumstances
6936 client tried to join to a channel it had already joined.
6938 * Added public key verification process into client's protocol.c.
6939 The client now verifies the public key from user and saves
6940 it into ~./silc/serverkeys/ directory.
6942 Added into: clientutil.[ch]: silc_client_verify_server_key.
6944 * Changed SKE protocol's silc_ske_initiator_finish function
6945 to accept callback function that verifies the received public
6946 key. Removed old silc_ske_verify_public_key function.
6948 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6950 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6951 silc_pkcs_private_key[_data]_set.
6953 * Made the password and public authentication more cleaner in
6954 server's protocol.c.
6956 * Removed historic and obsolete protocol `channel_auth' from
6957 both client and server.
6959 * Removed wrong way of sending command status messages from
6960 server to client in server's command.c. The old way violated
6961 protocol specification.
6963 Changes to silccore/silccommand.[ch]: removed
6964 silc_command_encode_status_payload -> not needed anymore,
6965 changed silc_command_encode_payload_va to accept extra
6966 argument on variable argument list. The argument type must
6967 now be provided to the function. Also, added new function:
6968 silc_command_encode_reply_payload_va which is same as
6969 normal command_encode_payload_va except command status type
6970 is provided as extra argument.
6972 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6974 * Added ~./silc directory handling. The directory includes the
6975 public and private keys for the client.
6977 Added silc_client_check_silc_dir, silc_client_create_identifier
6978 and silc_client_load_keys.
6980 * Implemented SILC protocol compliant public key. Added public
6981 and private key saving to and loading from files.
6983 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6984 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6985 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6986 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6987 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6989 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6990 silc_pkcs_load_[public/private]_key.
6992 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6994 * Added silc_server_get_route (route.[ch]) to get connection
6995 data for the fastest route for given ID.
6997 * Implemented INVITE command on client and server. The command
6998 were re-defined in the SILC Protocol Specification and the
6999 implementation now complies with the specification.
7001 * Implemented PING command on client and server.
7003 * Implemented NAMES command on client and server. The server side
7004 supports currently only normal server not router server yet.
7005 Some changes to NAMES definition in SILC protocol specification.
7007 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7009 * Implemented LEAVE command on client and server.
7011 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7012 again. This change was made to the protocol as well. Server
7013 should not violate the protocol specification anymore.

7017 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7018 was tested. SOCKS4 was not but should work anyway.
