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

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

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

119 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
120 Affected file lib/silcutil/silcnet.c.
122 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
124 * Fixed a bug in hash table internal routine for traversing
125 the table with foreach callback. The current entry may
126 become invalid in the callback but it was referenced after
127 the callback returned.
129 Do not allow auto rehashing of hash table during the
130 silc_hash_table_foreach operation, for same reasons as it is
131 not allowed for SilcHashTableList. Affected files are
132 lib/silcutil/silchashtable.[ch].
134 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
136 * Defined DLLAPI into silcincludes.h and silcwin32.h for
137 Win32 DLL. extern's in header files are now declared with
140 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
142 * Fixed private message handling. It used some old code that
143 caused the client to crash. Affecte file is
144 lib/silcclient/client_prvmsg.c.
146 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
148 * Added function silc_client_add_channel,
149 silc_client_replace_channel_id, and removed functions
150 silc_client_new_channel_id and silc_idlist_get_channel_by_id
153 * Added cross reference of the joined channels to the
154 SilcClientEntry, and changed the SilcChannelEntry's
155 users list to SilcHashTable. The affected files are
156 lib/silcclient/idlist.[ch].
158 * Fixed a bug in hash table tarversing. While the hash table
159 is traversed with SilcHashTableList the table must not be
160 rehashed. It is now guaranteed that auto rehashable tables
161 are not rehashed while tarversing the list. Also defined that
162 silc_hash_table_rehash must not be called while tarversing
163 the table. Added function silc_hash_table_list_reset that must
164 be called after the tarversing is over. The affected files are
165 lib/silcutil/silchashtable.[ch].
167 * Changed all hash table traversing to call the new
168 silc_hash_table_list_reset in server and in client library.
170 * Added function silc_client_on_channel to return the
171 SilcChannelUser entry if the specified client entry is joined
172 on the specified channel. This is exported to application as
173 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
175 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
177 * Fixed founder regaining problem with JOIN command on normal
178 server. The notify for mode change must be sent always and
179 not only if !cmd->pending. Affected file silcd/command.c.
181 * Fixed the WHOWAS command's reply sending to support the
182 lists correctly. Affected file silcd/command.c.
184 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
186 * When sending JOIN command to router for processing the
187 sender's old command identifier was not saved back to the
188 sender's command context, fixed now. The affected file is
191 * Create the key in JOIN command of the router did not return
192 the channel key, added check for this. Affected file is
195 * Fixed a channel ID update bug in JOIN command reply. Do
196 not directly upgrade the ID but call the function
197 silc_idlist_replace_channel_id if the ID was changed.
198 Affected file silcd/command_reply.c.
200 * Fixed memory leaks from command calling if it would fail.
201 Affected file silcd/command.c.
203 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
205 * Applied patches from cras:
207 Memory leak fixes around libaries, irssi window resize fix,
208 new silclist.h and silcdlist.h, all extern inline changed to
211 * Removed dotconf from lib/dotconf, not needed anymore.
213 * Removed TRQ from lib/trq, not needed anymore.
215 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
216 with server connections. Later this will be configurable
217 in config file after new config file is done. Affected file
220 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
222 * Fixed a crash in server related to channel announcements.
223 Affected file silcd/server.c.
225 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
227 * Fixed memory leaks in silc_server_create_new_channel*
228 functions. Affected file silcd/server.c.
230 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
231 which ID was changed. This way the router will send the
232 user list for the channel again, and server won't be in
233 desync in some rare circumstances. Affected file is
234 silcd/packet_receive.c.
236 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
238 * Check for NULL socket pointer in the function
239 silc_server_packet_send_to_channel_real. Affected file
242 * Fixed the BAN notify handling to correctly remove ban
243 list. Affected file silcd/packet_receive.c.
245 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
247 * Fixed some header addition to Toolkit distribution in
248 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
250 * Added lib/silcclient/client_ops_example.h as an template
251 file for application programmers to quickly start using
252 the SilcClientOperation functions in their application.
253 Updated the lib/silcclient/README as well to tell about this
254 nice file made available.
256 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
258 * Call silc_server_remove_from_channels when removing client
259 entry when NO_SUCH_CLIENT_ID was received. Affected file
260 is silcd/command_reply.c.
262 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
264 * Added server & router operator statistics updating. Affected
265 file silcd/packet_receive.c and silcd/command.c.
267 * Fixed the SERVER_SIGNOFF notify handling on normal server
268 not to save the history information for clients. Same was
269 fixed earlier in remove_clients_by_server function, but not
270 here. Affected file silcd/packet_receive.c.
272 * Raised the default connection-retry count from 4 to 7 in
273 server. Affected file silcd/server.h.
275 * Cancel any possible reconnect timeouts when we start the
276 key exchange. Affected file silcd/server.c.
278 * Do not reconnect on connection failure when SCONNECT was
279 given. Affected files silcd/server.[ch].
281 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
283 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
285 * Fixed the NICK command to always give the unformatted
286 nickname to the one giving the NICK command. If unformatted
287 nickname is cached already it will be formatted and the
288 local entry will always get the unformatted nickname.
289 Affected file lib/silcclient/idlist.c.
291 * Fixed some double frees from client library commands.
292 Affected file is lib/silcclient/command.c.
294 * Fixed CUMODE command in server to assure that no one can
295 change founder's mode than the founder itself, there was a
296 little bug. Affected file silcd/command.c.
298 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
300 * Removed the SilcClientCommandDestructor from the client
301 libary, it is not needed anymore. Affected files are
302 lib/silcclient/silcapi.h, command[_reply].[ch],
303 client_notify, idlist.c.
305 * Fixed GETKEY command to first resolve client, and then
306 resolve the server only if the client was not found, instead
307 of resolving both at the same time. Affected file is
308 lib/silcclient/command.c.
310 * Added silc_client_start_key_exchange_cb and lookup the
311 remote hostname and IP address before starting the key
312 exchange with server. The affected file is
313 lib/silcclient/client.c.
315 * The server's public key is now saved using the IP address
316 of the server and not the servername for the filename.
317 The hostname public key filename is checked as an fall back
318 method if the IP address based filename is not found.
320 Fixed the GETKEY command to save the fetched server key
323 Print the remote server's hostname now when new key is
324 received during connection process. Affected file is
325 irssi/src/silc/core/client_ops.c.
327 * Return always our own public key to the client if it asks
328 for it with GETKEY command. Affected file silcd/command.c.
330 * Removed the use_auto_addr variable from default config
331 file since it was in wrong section. Affected file is
334 * Fixed TOPIC_CHANGE notification to not route it when it
335 was sent using silc_server_send_notify_to_channel function.
336 Affected file silcd/command.c.
338 * Fixed silc_server_send_notify_kicked to send the kicker's
339 Client ID also, it was missing. Affected files are
340 silcd/command.c, silcd/packet_send.[ch].
342 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
344 * Do not save client history information in SERVER_SIGNOFF.
345 Fixes the bug in normal server that it does not detect
346 the client becoming valid after the server becomes back
347 online. Affected file silcd/server_util.c.
349 * Added `sock_error' field into the SilcSocketConnection
350 context. When error occurs during socket operation (read
351 or write) the error is saved. Added also new function
352 silc_socket_get_error to return human readable socket error
353 message. Affected files are lib/silcutil/silcsockconn.[ch],
354 lib/silcutil/unix/silcunixsockconn.c, and
355 lib/silcutil/win32/silcwin32sockconn.c.
357 * The server now prints the socket error message in the
358 signoff for client. Affected file silcd/server.c.
360 * Fixed the `created' channel information sending from router
361 to server in JOIN command. Checks now whether the channel
362 really was created or not and set it according that.
364 Fixed the JOIN command to use the client entry's current
365 ID during the joining procedure instead of the one it sent
366 in the command (it is checked though), since it can change
367 between the packet processing and command processing, and
368 would just case unnecessary pain in the client end. Affected
369 file silcd/command.c.
371 * Fixed a channel key payload sending to use correct channel
372 ID when the server was forced to change the channel's ID by
373 router. Router sent the key payload with the old Channel ID.
374 Affected file silcd/packet_receive.c.
376 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
378 * Call silc_server_save_channel_key only if the key payload
379 was provided in the JOIN command's command reply. Affected
380 file silcd/command_reply.c.
382 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
384 * Fixed silc_mp_sizeinbase to return the value correctly with
385 MPI. Affected file lib/silcmath/mp_mpi.c.
387 * Fixed the stop_server signal to correctly stop the scheduler
388 and gracefully stop the server when SIGTERM or SIGINT signals
389 are received. Affected file silcd/silcd.c.
391 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
393 * Simple handling of TERM and HUP signals. Also added some log
394 flushing call around. Affected file is
397 * Fixed small bugs in silclog.c. Now buffering output will take
398 effect after 10 seconds since startup: This will ensure that
399 no important startup messages are lost. Also output redirection
400 will preserve original format ([Date] [Type] message).
401 Affected file is lib/silcutil/silclog.c.
403 * Added two options to the config file, in the logging section:
404 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
405 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
407 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
409 * Do not print the warning about log files not being initialized
410 more than once to avoid excess logging. Affected file is
411 lib/silcutil/silclog.c.
413 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
414 the SIM copying in make install in Makefile.am.pre.
416 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
418 * Rewritten silclog APIs. Globally interesting changes follows:
419 silc_log_set_files() changed to silc_log_set_file().
420 silc_log_set_callbacks() changed to silc_log_set_callback().
421 ROBOdoc documented silclog header file.
422 SilcLogCb now returns bool to wether inihibit the default
423 handler or not (to keep the old behaviour return always TRUE).
424 The new APIs should also fix the problem of the
425 silcd_error.log file that was written in the current directory.
428 Log files streams will remain opened after silc_log_set_file()
429 call, means less CPU usage notably on high traffic servers.
430 File streams are now full buffered, and flushed to the disk
431 every 5 minutes, lesses HD activity and CPU usage.
432 Messages can be redirected, allowing admins to configure
433 one single logfile for all server messages.
434 the silc_log_quick global variable to activate fast-logging.
435 Affected files lib/silcutil/silclog.[ch]
437 * Changed some code to conform new silclog APIs. Affected
438 files are doc/example_silcd.conf.in, silcd/server.c
439 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
442 * Fixed a memory leak that could occur in some situations.
443 Affected file silcd/serverconfig.c.
445 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
447 * Added the silc_client_del_client to remove the client from
448 all channels as well. Affected file lib/silcclient/idlist.c.
450 * Fixed the client library to correctly remove the client
451 from all channels when the client entry is being destroyed.
452 Affected file lib/silcclient/client_notify.c, command.c.
454 * Added auto-nicking support to the client library. If the
455 applicatio now sets client->nickname it will be sent to the
456 server after connecting by the library. This way for example
457 SILCNICK (or IRCNICK) environment variables will have effect
458 and always change the nickname automatically to whatever
459 it is wanted. Affected file lib/silcclient/client.[ch].
461 * Renamed silc_server_command_bad_chars to the
462 silc_server_name_bad_chars and moved it to the
463 silcd/server_util.[ch]. Added also new function
464 silc_server_name_modify_bad to return nickname that
465 includes bad characters as new nickname without those
466 bad characters. This check and modify is now used in
467 silc_server_new_client when the username is initially set
468 as nickname, so it must be checked to be valid nickname.
469 Affected file silcd/packet_receive.c.
471 * The nickname length is now taken from the packet for real
472 and not trusted to strlen() since it clearly can return
473 wrong length for nickname including bad characters. This
474 also applies to channel names. Affected file silcd/command.c.
476 * Removed the lib/silcsilm/modules directory. Modules are now
477 compiled into the lib/silcsim. Fixed the copying of the
478 modules to follow symbolic links in Makefile.am.pre.
480 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
482 * Fixed silc_string_regexify list creation. Fixes bugs with
483 BAN and INVITE commands in server. The affected file is
484 lib/silcutil/unix/silcunixutil.c.
486 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
488 * Removed the command destructor entirely from the server's
489 command and command reply routines. It is not needed, and
490 its usage was buggy and caused crashes. Affected files are
491 silcd/command[_reply].[ch].
493 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
495 * Cancel protocol and NULL sock->protocol if timeout
496 occurred during protocol. Affected file silcd/server.c.
498 * Cancel protocol timeouts always before calling the final
499 callback, to assure that after final callback is called
500 no other state will be called for the protocol anymore.
501 Affected file silcd/protocol.c.
503 * Print error log if incoming connection configuration could
504 not be found. Affected file silcd/server.c.
506 * Fixed JOIN command to correctly save the founder mode
507 to the client on normal SILC server, when the channel
508 was created by the router. Affected file silcd/command.c.
510 * Fixed LIST command (hopefully) to send correct reply
511 packets. Affected file silcd/command.c.
513 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
515 * The silc_packet_receive_process now returns FALSE if the
516 read data was invalid packet, and TRUE if it was ok.
518 The server now checks that if unauthenticated connection
519 sends data and its processing fails the server will close
520 the connection since it could be a malicious flooder.
522 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
524 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
526 * Make sure the warning about error opening a log file is
527 printed only once and not everytime it fails (produces
528 too much useless log). Affected file lib/silcutil/silclog.c.
530 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
532 * Made the silc_server_daemonise() function more readable.
533 Affected file silcd/server.c.
535 * Pid file is now optional, the user may comment it out from
536 the config file. Removed define SILC_SERVER_PID_FILE, we
537 don't need a default any longer. Affected file
538 configure.in.pre, lib/Makefile.am.pre.
540 * Make some use of the pid file. The server now dies at startup
541 if it detects a valid pid file on his path. The server would
542 die anyway in this circumstance, because of the bind() failure.
543 Affected file silcd/silcd.c.
545 * No longer compiling lib/dotconf.
547 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
549 * Fixed JOIN command parsing not to crash. Affected file
550 lib/silcclient/command.c.
552 * Fied the NICK_CHANGE notify to add the new client entry
553 even it is resolved. This removes an <[unknown]> nick
554 thingy bug in the client. Affected file is
555 lib/silcclient/client_notify.c.
557 * Do not try to allocate 0 bytes (efence does not like it)
558 in lib/silccore/silccomand.c when encoding payload.
560 * Do not take IRCNICK as nickname in Irssi SILC client since
561 it is not possible to set nickname before hand connecting
562 the server (TODO has an entry about adding auto-nicking
565 * Changed the silc_server_command_pending to check whether
566 there already exists an pending entry with the specified
567 command, command identifier and pending callback. This is
568 to fix IDENTIFY and WHOIS related crashes that may register
569 multiple pending commands with same identifier. Affected
570 file silcd/command.c.
572 * Fixed the server to reconnect to the router even if it
573 was already reconnecting and EOF was received. This to
574 fix a possibility that the server wouldn't ever try to
575 auto-reconnect to the router. Affected file silcd/server.c.
577 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
579 * Fixed the server's password authentication to use the
580 length of the locally saved password, and not the one
581 sent in the packet. Affected file silcd/protocol.c.
583 * Fixed same password authentication problem in the
584 Authentication Payload handling routines in
585 lib/silccore/silcauth.c.
587 * Yet another password authentication problem fixed with
588 channel password handling in silcd/command.c.
590 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
592 * If first character of string in silc_parse_userfqdn is '@'
593 then do not parse it. Affected file is
594 lib/silcutil/silcutil.c.
596 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
598 * Fixed minor bug in IDENTIFY command reply sending, which
599 caused various weird problems during JOIN when it was
600 resolving names for users. Affected file silcd/command.c.
602 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
604 * Fixed the IDENTIFY command reply sending to chech better valid
605 clients. It was possible to send incomplete list of replies.
606 Affected file silcd/command.c.
608 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
610 * Added silc_client_command[s]_[un]register functions now to
611 dynamically register the commands in client library. Removed
612 the static table of commands. This allows the client library
613 to call commands without causing the application to know about
614 what commands library has called.
616 Removed the INFO command reply kludge to detect when the command
617 was called by library. Now library use its own command reply
618 function for INFO command.
620 Added function silc_client_command_call to call a command.
621 Application can use it to call command, not access the structure
624 Now all commands that are sent by the client library (not
625 explicitly sent by application) use own command reply functions.
627 Affected files around lib/silcclient/ and in
628 irssi/src/silc/core/.
630 * Fixed the WHOIS command reply sending to chech better valid
631 clients. It was possible to send incomplete list of replies.
633 Fixed the WHOIS and IDENTIFY to send the request to router
634 if normal server did not do it and did not find any results.
636 Affected file silcd/command.c.
638 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
640 * Moved the internal data from SilcClient context into its
641 own file, not accesible to application. Affected files
642 lib/silcclient/client.h and lib/silcclient/client_internal.h,
643 and other files in client library.
645 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
647 * Added doc/examples installation target in Makefile.am.pre.
650 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
652 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
653 commands the found client entry will be removed from the
654 cache, after notifying application about the error. Affected
655 file lib/silcclient/command_reply.c.
657 * Changed the /MSG to check for exact nickname user gave, and
658 not let `nick' match `nick@host' if it is only one found. Now,
659 user must type the exact nickname (like nick@host2) even if
660 there are no more than one same nicks found. This is to avoid
661 a possibility of sending nickname to wrong nickname since
662 `nick' could match `nick@host'. Affected file is
663 irssi/src/core/silc-servers.c.
665 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
667 * Do not print "you are now server operator" or similar when
668 giving /away command. Affected files are
669 irssi/src/silc/core/client_ops.c, silc-servers.h.
671 * Made the silc_server_command_pending_error_check to send
672 the same command reply payload it received back to the
673 original sender of the command. This way all arguments
674 that was received by the server will be received by the
675 client too. Affected file silcd/command.c.
677 * Added the silc_idcache_add to return the created cache entry
678 to a pointer. Affected file lib/silccore/silcidcache.[ch].
680 * Add global clients to expire if they are not on any channel.
681 This is because normal server will never know if they signoff
682 if they are not on any channel. The cache expiry will take
683 case of these entries. This is done by normal servers only.
684 The affected files are silcd/command_reply.c,
685 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
687 * If server receives invalid ID notification for WHOIS or
688 IDENTIFY and the ID exists in the lists, it is removed.
689 Affected file silcd/command_reply.c.
691 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
692 in client then client entry that it matches is searched and
693 the nickname is printed on the screen for user. Affected
694 file irssi/src/silc/core/client_ops.c.
696 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
698 * Use cache entry expire time in the LIST command reply to
699 purge old entries from the cache after the LIST command
700 reply has been received. This way we don't have non-existent
701 entries in the cache for too long. Affected file is
702 silcd/command_reply.c.
704 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
706 * If we are normal server, and we've not resolved client info
707 in WHOIS or IDENTIFY from router, and it is global client,
708 we'll check whether it is on some channel. If it is not
709 then we cannot be sure about its validity and will resolve it
710 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
711 file silcd/command.c.
713 * Search channel by name (if possible) rather than by ID
714 in IDENTIFY command's command reply. Affected file is
715 silcd/command_reply.c.
717 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
719 * Distribute to the channel passphrase in CMODE_CHANGE notify.
720 Updated specs and implemented it. Affected file silcd/command.c,
721 silcd/packet_send.c and silcd/packet_receive.c.
723 * Implemented the <founder auth> payload handling in the JOIN
724 command. If provided all conditions for channel joining
725 except requirement to provide correct passphrase can be
726 overrided by the channel founder. Updated the protocol specs.
727 Affected file silcd/command.c.
729 Added support for founder auth in JOIN command in client
730 library. Fixed the parsing of the JOIN command now to support
731 all options as they should be. The affected file is
732 lib/silcclient/command.c.
734 * Optimized the WHOIS and IDENTIFY commands to send the request
735 to router only if it includes nicknames or other names. If
736 they include only IDs then check the local cache first before
737 routing. Affected file is silcd/command.c.
739 * Added channels topic announcements. Affected file is
740 silcd/packet_receive.c and silcd/server.c.
742 * Fixed the silc_server_send_notify_topic_set to really destine
743 the packet to channel. Affected file silcd/packet_send.c.
745 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
746 library. Affected file lib/silcclient/client_notify.c.
748 * Added UMODE announcements. Affected file silcd/server.c.
750 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
752 * Memory leak fixes in:
754 lib/silcutil/silcsockconn.c
755 lib/silcske/silcske.c
758 lib/silccrypt/silcpkcs.c
759 lib/silccore/silccommand.c
760 lib/silccore/silcidcache.c
765 * ROBOdoc documented the lib/silcske/groups.h file and a
766 bit changed the interface for better.
768 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
770 * Update the client entry context in the ID cache after
771 nick change. Affected file lib/silcclient/command.c.
772 Fixes the CUMODE command when regaining founder privileges,
773 and a little WHOIS problem.
775 * Fixed silc_net_gethostbyname to correctly call the
776 inet_ntop. Affected file lib/silcutil/silcnet.c.
778 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
780 * Added IPv6 support checking to the configure.in.pre, added
781 also --enable-ipv6 option to override the check. Affected
782 file configure.in.pre.
784 * The silc_thread_create now calls the start function
785 directly if threads support is not compiled in. Removes
786 ugly #ifdef's from generic code. Affected files are
787 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
789 * Added silc_net_gethostby[name/addr]_async to asynchronously
790 resolve. Affected files are lib/silcutil/silcnet.[ch].
792 * Added support for rendering IPv6 based server, client and
793 channel IDs. Affected file lib/silcutil/silcutil.c.
795 * Added support for creating IPv6 based server IDs. Affected
796 file is silcd/serverid.c.
798 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
800 * Added silc_net_gethostby[addr/name] into the
801 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
802 routines. Added silc_net_is_ip[4/6]. Affected file is
803 lib/silcutil/unix/silcunixnet.c. All routines that take
804 address as argument now supports both IPv4 and IPv6 addresses.
806 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
808 * Fixed LIST command reply sending in server. Affected file
811 * Server now sends the kicker's client ID in the KICK notify
812 to the kicked client. Affected file silcd/command.c.
814 * The client library now parses the kickers client ID and
815 UI displays it. Affected files lib/silcclient/client_notify.c
816 and irssi/src/silc/core/silc-channels.c, module-formats.c.
818 * Made all payload parsing function prototypes consistent.
819 They all take now const unsigned char * and uint32 pair as
820 the payload data instead of SilcBuffer. Changes all around
821 the source tree. Other unsigned char* -> const unsigned char*
822 changes around the tree as well.
824 * Optimized SFTP client and server packet sending not to
825 allocate new buffer for each packet but to recycle the
826 first allocated buffer. Affected files are
827 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
829 * Optimized the SFTP client to use SilcList instead of
830 SilcDList for requests, because it is faster. Affected file
831 is lib/silcsftp/sftp_client.c.
833 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
834 into lib/silccore/silcid.[ch].
836 Renamed silcpayload.[ch] into silcargument.[ch].
838 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
840 * If client entry is deleted with active key agreement
841 session, abort the session.
843 The silc_client_abort_key_agreement now calls the completion
844 callback with new SILC_KEY_AGREEMENT_ABORTED status.
846 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
849 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
851 * Don't use __restrict in older GCC's. Affected file is
852 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
854 * silc_net_localhost now attempts to reverse lookup the
855 IP/hostname. Affected file lib/silcutil/silcnet.c.
857 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
858 command. It can be used to gain founder privileges at
859 the same time when joining the channel.
861 Defined that the SILC_NOTIFY_TYPE_KICKED send the
862 kicker's client ID as well. Updated protocol specs.
864 Defined that the server must send SILC_COMMAND_IDENTIFY
865 command reply with error status to client who sent
866 private message with invalid client ID.
868 Updated the protocol specification.
870 * Added silc_server_send_command_reply to send any
871 command reply. Affected file silcd/packet_send.[ch].
873 * Added silc_id_payload_encode_data to encode ID payload
874 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
876 * The server now send IDENTIFY command reply with error
877 status if client ID in private message is invalid. Affected
878 file silcd/packet_receive.c.
880 * Save the server key file with server's IP address in
881 the filename instead of hostname. The affected file is
882 irssi/src/silc/core/client_ops.c.
884 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
886 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
889 * Added libtool support for compiling shared objects in
890 lib/silcsim. Affected file configure.in.pre and
891 lib/silcsim/Makefile.am. Original patch by cras.
893 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
895 * Pid file configuration, and server's config file fixes
896 patch by toma. Updated CREDITS file.
898 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
900 * Fixed silc_client_channel_message to not try to decrypt
901 the message twice if it resolved the destination client
902 information. This could cause of dropping one channel
903 message. Affected file lib/silcclient/client_channel.c.
905 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
907 * Added silc_client_run_one into lib/silcclient/silcapi.h and
908 lib/silcclient/client.c. This function is used when the SILC
909 Client is run under some other scheduler, or event loop or
910 main loop. On GUI applications, for example this may be
911 desired to used to run the client under the GUI application's
912 main loop. Typically the GUI application would register an
913 idle task that calls this function multiple times in a second
914 to quickly process the SILC specific data.
916 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
918 * Fixed silc_server_drop() for dropping the supplementary
919 groups as well, this could cause a security hole on some
922 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
924 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
927 * Write PID file after dropping privileges. Added -F option
928 to run server on foreground. A patch by debolaz.
929 Affected files silcd/server.c, silcd/silcd.c.
931 * Fixed MOTD to return the MOTD file server name. Affected
932 file silcd/command.c.
934 * Added INFO command reply handling to the Irssi SILC Client.
935 Affected file irssi/src/silc/core/client_ops.c.
937 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
939 * Fixed the silc_idcache_list_* routines to really support
940 the dynamic list. Fixes a crash. Affected file is
941 lib/silccore/silcidcache.c.
943 * Fixed the LIST command reply to really call LIST command's
944 pending callbacks. Affected file silcd/command_reply.c.
946 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
948 * Update conn->local_entry->nickname after giving NICK
949 command. Affected file lib/silcclient/command.c.
951 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
953 * Added the [pid] option to the silcd configuration file
955 Affected files: serverconfig.[ch] and silcd.c
957 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
959 * Save fingerprint in WHOIS command reply in server.
960 Affected file silcd/command_reply.c.
962 * Fixed NICK commands pending callback registration.
963 Affected file lib/silcclient/command.c.
965 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
967 * Use ++server->cmd_ident when sending commands in server,
968 instead of random number. Affected file silcd/command.c.
970 * Fixed GETKEY command reply to call actually GETKEY pending
971 command callbacks. Affected file silcd/command_reply.c.
973 * A bit stricter check for nicknames. Check for same nickname
974 in NICK command also. Affected file silcd/command.c.
976 * Do not call INFO command everytime client ID changes, only
977 during first connecting. Affected file lib/silcclient/client.c.
979 * Set the new nickname only after successful command reply for
980 NICK command is returned by server. Affected file
981 lib/silcclient/command.c.
983 * Remove nicknames from nicklist during server_signoff notify.
984 Should fix /NAMES bit more. The affected file is
985 irssi/src/silc/core/silc-channels.c.
987 * Added `fingerprint' field to the SilcIDListData in the
988 silcd/idlist.h to hold the fingerprint of the client's
991 Send the fingerprint of the client's public key in WHOIS
994 Affected files silcd/command.c, and silcd/idlist.[ch].
996 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
997 create fingerprint from given data.
999 * Show the fingerprint of the client's public key in WHOIS.
1000 Affected files irssi/src/module-formats.[ch] and
1001 irssi/src/silc/core/client_ops.c.
1003 * Format the multiple same nicknames also during JOIN and
1004 NICK_CHANGE notifys. Affected file is
1005 lib/silcclient/client_notify.c.
1007 * Do not print error on screen for invalid private message
1008 payload since it can come if someone is sending private
1009 messages with wrong key. Affected file
1010 lib/silccore/silcprivate.c.
1012 * Fixed multiple concurrent /PING crash. Affected file
1013 lib/silcclient/command.c.
1015 * Changed the wrong ID encoding. All IP addresses must be
1016 in MSB first order in encoded format. They were encoded
1017 wrong and was in LSB format. Affected files are
1018 silcd/serverid.c, lib/silcutil/silcutil.c.
1020 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1022 * Call the `connect' client operation through the scheduler
1023 in case of error. Affected file lib/silcclient/client.c.
1025 * Call the `failure' client operation even if the error
1026 occurred locally during a protocol. Affected file is
1027 lib/silcclient/protocol.c.
1029 * Added support of sending LIST command to router from normal
1030 server. This way normal server can get list of all channels
1031 in the network too. Fixed the channel list sending in the
1032 server too. Affected files are silcd/command.c, and
1033 silcd/command_reply.[ch].
1035 * Added silc_server_update_channels_by_server and
1036 silc_server_remove_channels_by_server. They are used during
1037 disconnection of primary router and in backup router protocol.
1038 Affected file silcd/server_util.[ch], silcd/server.c and
1039 silcd/server_backup.c.
1041 * Fixed channel adding to global list in IDENTIFY command
1042 reply in server. Affected file silcd/command_reply.c.
1044 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1046 * If the incoming packet type is REKEY or REKEY_DONE process
1047 that packet always synchronously. Fixes yet another MAC
1048 failed error on slow (dialup) connections. Affected file
1049 lib/silcclient/client.c and silcd/server.c.
1051 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1053 * Call check_version SKE callback for initiator too. Affected
1054 file lib/silcske/silcske.c.
1056 * Implemented fix for security hole found in the SKE that was
1057 fixed in the specification few days back; the initiator's
1058 public key is now added to the HASH value computation.
1059 Added backwards support for the old way of doing it too, for
1060 old clients and old servers. Affected file is
1061 lib/silcske/silcske.c.
1063 * Enabled mutual authentication by default in SKE. If initiator
1064 is not providing mutual authentication the responder will
1065 force it. This will provide the proof of posession of the
1066 private key for responder. The affected files are
1067 lib/silcclient/protocol.c and silcd/protocol.c.
1069 * Do not cache anymore the server's public key during SKE.
1070 We do mutual authentication so the proof of posession of
1071 private key is done, and if the server is authenticated in
1072 conn auth protocol with public key we must have the public
1073 key already. Affected file silcd/protocol.c.
1075 * Added new global debug variable: silc_debug_hexdump. If
1076 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1077 file lib/silcutil/silclog.[ch].
1079 * Fixed compilation warning due to char * -> const char *.
1080 Affected files lib/silcutil/silcnet.h, and
1081 lib/silccore/silcauth.[ch].
1083 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1085 * Fixed CMODE command when new channel key was created. If
1086 the creation failed the old key was removed. Next time giving
1087 same command would crash the server since the old key was
1088 freed already. Affected file silcd/command.c.
1090 * Fixed the silc_server_announce_get_channels to not crash
1091 on reconnect. Affected file silcd/server.c.
1093 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1095 * Added silc_log_set_debug_string function to set a regex
1096 string to match for debug output. Only the function names,
1097 or filenames matching the given debug string is actually
1098 printed. This way it is possible to filter out those debug
1099 strings that user is not interested in.
1101 Fixed a bug in silc_string_regexify.
1103 Affected files lib/silcutil/silclog.[ch], and
1104 lib/silcutil/unix/silcunixutil.c.
1106 * Changed the -d options in both server and Irssi SILC client
1107 to take the debug string as argument. Affected files
1108 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1110 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1112 * Added silc_hash_babbleprint to create a Bubble Babble
1113 Encoded fingerprint. The encoding is developed by Antti
1114 Huima (draft-huima-babble-01.txt), and it creates human
1115 readable strings out of binary data. Affected file
1116 lib/silccrypt/silchash.[ch].
1118 * Print the babble print now in addition of fingerprint as well
1119 in Irssi SILC client. Affected files are
1120 irssi/src/fe-common/silc/module-formats.[ch],
1121 irssi/src/fe-common/silc/core/client_ops.c.
1123 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1125 * Fixed a security problem found in SKE. The initiator's
1126 public key too is now added to the HASH hash value creation
1127 which is signed by the responder to create the SIGN value.
1128 This will prevent anyone in the middle to lie to the responder
1129 about the initiator's public key. If this is done now, the
1130 man in the middle will get caught. Updated the protocol
1133 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1135 * Better installation directory handling. Configure module
1136 paths and other paths automatically to example_silc* files
1137 in doc/. A patch by toma.
1139 * Fixed compiler warning from MPI library, and from SILC RNG.
1142 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1143 It can be configured with ./configure. A patch by toma.
1145 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1147 * Find correct make to use in prepare-clean. A patch by
1148 toma. Affected file prepare-clean.

1167 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1169 * Added silc_pkcs_public_key_compare to compare two
1170 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1172 * Check that the client who set the founder mode on the
1173 channel is the same client that is giving the founder
1174 mode to itself. It is done by comparing the saved public
1175 key (it is saved even in the authentication is passphrase).
1176 Affected file silcd/command.c.

1183 * Process the DISCONNECT packet through scheduler in the
1184 client library. Affected file lib/silcclient/client.c.
1186 * Fixed the silc_client_packet_parse to not to increase
1187 the packet sequence number if the conn->sock and the
1188 current socket connection is not same. This can happen
1189 for example during key agreement when the conn includes
1190 multiple socket connections (listeners). Affected file
1191 lib/silcclient/client.c.
1193 * The sender of the file transfer request now provides also
1194 the pointer (listener) for the key exchange protocol. If
1195 the listener cannot be created then it sends empty key
1196 agreement and lets the receiver provide the listener.
1198 Added `local_ip' and `local_port' arguments to the
1199 silc_client_file_send. If they are provided they are used,
1200 if not then it will attempt to find local IP address, if
1201 not found or bind fails then the remote client will provide
1204 Affected files are lib/silcclient/client_ftp.c and
1205 lib/silcclient/silcapi.h.
1207 * Extended the FILE SEND command to support defining the
1208 local IP and port for key exchange listener. They are
1209 optional. Affected file irssi/src/silc/core/silc-servers.c.

1213 * Defined to WHOIS command reply the sending of fingerprint
1214 of the client's public key (if the proof of posession of the
1215 corresponding private key is verified by the server).
1216 Updated to the protocol specification.
1218 * Added support of receiving the client's public key's
1219 fingerprint in command reply in client library. Affected
1220 file is lib/silcclient/command_reply.c, and
1221 lib/silcclient/idlist.[ch].
1223 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1276 client library. Affected file lib/silcclient/client_prvmsg.c.
1278 * Do not actually remove the client directly from ID cache
1279 during SERVER_SIGNOFF, but invalidate it. This way we
1280 preserve the WHOWAS info for the client. Affected file
1281 silcd/server_util.c.
1283 * Fixed SERVER_SIGNOFF notify handling in the server. The
1284 server is now able to process incoming SERVER_SIGNOFF notify
1285 for a server that it doesn't even know about. It will remove
1286 the clients provided in the notify. Affected file
1287 silcd/packet_receive.c.
1289 * Check for partial packet in data queue after every packet that
1290 was found from the queue. Return and wait for more data if
1291 there is partial data in queue. Affected file is
1292 lib/silccore/silcpacket.c.
1294 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1296 * Added SilcClietFileError enum to indicate error in
1297 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT

1299 Affected files lib/silcclient/silcapi.h and
1300 lib/silcclient/client_ftp.c.
1302 * Check that newsize in silc_buffer_realloc is larger than
1303 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1305 * Added better monitor of file transfers. It now monitors
1306 key agreement protocol during the file transfer too. Added
1307 error reporting too. Affected files

1309 irssi/src/fe-common/silc/module-formats.[ch].
1311 * Wrote a help file for FILE command.
1313 * Added silc_rng_global_get_byte_fast to get not-so-secure
1314 random data as fast as possible. Random data is read from
1315 /dev/urandom if available and from the SILC RNG if not
1316 available. It is used in padding generation. Affected file
1317 lib/silccrypt/silcrng.[ch].
1319 * All packets in client library are now processed synchronously.
1320 Optimized packet processing a lot. Affected file
1321 lib/silcclient/client.c.
1323 * All server connection packets are processing synchronously
1324 now in server, to optimize packet processing. Affected file
1327 * Include files are installed now only in Toolkit distribution
1328 if make install is given. Affected files: all Makefile.am's.
1330 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1332 * Assure that silc_client_notify_by_server_resolve does not
1333 resolve the client information multiple times. If it cannot
1334 be found by the first it cannot be found at all. Affected
1335 file lib/silcclient/client_notify.c.
1337 * Fixed WHOWAS command reply calling. Affected file
1338 lib/silcclient/command_reply.c.
1340 * Removed all references to silc_idlist_get_client from the
1341 Irssi SILC client since that call is internal call used by
1342 the library. The Irssi SILC client will use now client
1343 retrieval functions found in silcapi.h.
1345 * Fixed a bug in resolving nickname info before sending
1346 private message. It used freed memory. Affected file
1347 irssi/src/silc/core/silc-servers.c.

1368 * Added silc_net_localip to return local host's IP address.
1369 Affected file lib/silcutil/silcnet.[ch].
1371 * If key exchange or rekey protocol is active for a connection
1372 parse all packets syncronously since there might be packets
1373 in packet queue that we are not able to process without first
1374 processing packets before them. Affected file silcd/server,
1375 lib/silcclient/client.c.
1377 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1378 whether library should continue processing the packet.
1379 Affected file lib/silccore/silcpacket.h.
1381 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

1425 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1426 is incomplete and is being resolved, it won't be resolved
1429 Make sure also that USERS command reply does not resolve
1430 twice information. Affected file is
1431 lib/silcclient/command_reply.c.
1433 Make sure that silc_client_get_clients_by_list does not
1434 resolve twice same information.
1436 * Check for valid client->id in the silc_server_free_client_data.
1437 Affected file silcd/server.c.
1439 * Fixed /GETKEY nick@server not to crash if the server entry
1440 is not found. Affected file lib/silcclient/command.c.
1442 * Fixed the silc_server_check_cmode_rights to check the
1443 requested modes correctly. Affected file silcd/command.c.

1450 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1452 * Call the silc_server_udpate_servers_by_server in the
1453 primary router that comes back online in the backup resuming
1454 protocol. Otherwise it routes packets wrong. Affected file
1455 silcd/server_util.[ch], silcd/server_backup.c.
1457 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1459 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1460 lib/silcutil/silcbuffmt.[ch].
1462 * Redefined the SILC packet header to include the padding
1463 length. Affected file lib/silccore/silcpacket.[ch].
1465 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1466 length for maximum padding up to 128 bytes). Affected
1467 file lib/silccore/silcpacket.h.
1469 * Removed all backwards support for old 0.5.x MAC thingies.
1470 The SILC packet header change makes it impossible to be
1471 backwards compatible.
1473 * Send the ENDING packet with timeout in the backup resuming
1474 protocol. This is to assure that all routers has connected
1475 to the primary router. Affected file silcd/server_backup.c.
1477 * Changed the RNG to take the first IV from random data. It
1478 used to take it from zero actually. Changed the RNG also
1479 to use /dev/urandom during session. /dev/random is used
1480 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1482 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1484 * Changed the SILC packet header to have the first two bytes
1485 (the packet length) encrypted. Affected files aroung the
1486 code tree, lib/silccore/silcpacket.[ch]. Removed the
1487 SilcPacketCheckDecrypt callback. It is not needed anymore
1488 since the silc_packet_receive_process will determine now
1489 whether the packet is normal or special.
1491 * Implemented the unidirectional MAC keys. Affected files
1492 lib/silcske/silcske.c, silcd/protocol.c and
1493 lib/silcclient/protocol.c.

1500 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1502 * Allow backup router to announce servers. All servers
1503 announced by backup router are added to the global list
1504 automatically. Update hte server's socket to our primary
1505 router also when backup router announces a server.
1506 Affected file silcd/packet_receive.c.
1508 * Do not update the client->router in the function
1509 silc_server_udpate_clients_by_server if the client is on
1510 global list. We might fail to find any specific server
1511 for locally connected clients and local cell clients. They
1512 should still use the `from' and not `to' as client->router.
1513 This fixes backup router resuming protocol. Affected file
1514 silcd/server_util.c.
1516 * Decrease channel statistics count only if the channel
1517 deletion worked. Affected files are silcd/server.c and
1518 silcd/server_util.c.
1520 * Added silc_server_update_servers_by_server to update origin
1521 of all server entries. Used during backup router protocol.

1530 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1532 * Assure that router cannot reroute the same channel message
1533 to the sender. Affected file silcd/packet_receive.c.
1535 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1537 * Made better checks that the channel message is not sent
1538 to the router it came from. Affected file is
1539 silcd/packet_send.c. Fixed memory leak too.
1541 * Announce informations for incoming router connection, but
1542 only after checking if it is replaced by backup router.
1543 Affected file silcd/packet_receive.c.
1545 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1547 * Fixed the backup resuming protocol to work in multiple
1548 router environment. Affected file silcd/server_backup.c.
1550 * Route packet only to one router in the function
1551 silc_server_packet_send_to_channel. Affected file is
1552 silcd/packet_send.c.
1554 * Fixed silc_server_send_notify_dest to set the broadcast
1555 flag. Fixed the silc_server_send_notify_topic to actually
1556 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1557 Affected file silcd/packet_send.c.
1559 * Changed the SFTP Filesystem interface. Changed the
1560 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1561 the filesystem operation function. The SilcSFTPFilesystem
1562 is now a context that is allocated by all filesystem allocation
1563 functions and it already includes the operations structure
1564 and filesystem specific context. It is given as argument
1565 now to the silc_sftp_server_start. This made the interface
1566 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1567 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1569 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1571 * Changed the backup router adding and getting interfaces
1572 in the server. The router that will be replaced by the
1573 specified backup router is now sent as argument. Affected
1574 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1577 * Added silc_net_addr2bin_ne to return the binary form of
1578 the IP address in network byte order. Affected files
1579 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1581 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1583 * Check for existing server ID in silc_server_new_server
1584 and in silc_server_connect_to_router_final and remove the
1585 old entry if it exists. Affected file silcd/packet_receive.c,
1588 * Send the channel message always to only one router, either
1589 in upstream or downstream. Affected file is
1590 silcd/packet_send.c.
1592 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1594 * Wrote the definition of the backup resuming protocol to the
1595 protocol specification.
1597 * Removed one redundant channel key generation from normal
1598 server during joining procedure. Removed one redundant
1599 channel key sending from server to router during joining
1600 procedure. Affected file silcd/command.c.
1602 * Made minor bugfixes to the backup router resuming protocol.
1603 Affected file silcd/server_backup.c, server.c.
1605 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1608 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1611 * Implemented the backup resuming protocol that is used to
1612 resume the primary router position in the cell after the
1613 primary router comes back online. Affected files
1614 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1615 and silcd/server_util.[ch].
1617 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1619 * Sleep two (2) seconds after sending QUIT command to server.
1620 Affected file lib/silcclient/command.c.
1622 * Assure that if outgoing data buffer is pending do not force
1623 send any data. Affected file silcd/packet_send.c.
1625 * Assure that if outgoing data buffer is pending do not force
1626 send any data. Affected file lib/silcclient/client.c.
1628 * Implemented the backup router support when the primary router
1629 goes down. The servers and routers can now use the backup
1630 router as new primary router without loosing connectivity.
1632 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1634 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1635 in the server to indicate disabled entry. All data read
1636 from the connection will be ignored and no data is sent
1637 for entry that is disabled. Affected files are
1638 silcd/idlist.h, silcd/server.c.
1640 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1642 * Created SFTP client and server test programs in the
1643 lib/silcsftp/tests directory.
1645 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1647 * Implemented memory filesystem (virtual filesystem) for
1648 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1651 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1653 * Implemented the SFTP (SSH File Transfer Protocol) to the
1654 lib/silcsftp. It includes SFTP client and SFTP server
1657 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1659 * Moved lib/silccore/silcprotocol.[ch] to the
1660 lib/silcutil library.
1662 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1663 take variable argument list pointer as argument. Affected
1664 file lib/silcutil/silcbuffmt.[ch].
1666 * Added silc_buffer_set function that is used to set data
1667 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1668 Affected file lib/silcutil/silcbuffer.h.
1670 * Changed various routines in the core library to use the new
1671 silc_buffer_set instead of allocating new buffer only for
1674 * Added 64-bit value formatting and unformatting support to the
1675 silc_buffer_[un]format routines. Affected file is
1676 lib/silcutil/silcbuffmt.[ch].
1678 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1679 to includes/bitmove.h.
1681 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1683 * Fixed channel user mode saving in client library. Affected
1684 file lib/silcclient/command[_reply].c.
1686 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1688 * Defined the file transfer to the SILC Protocol. Added
1689 new packet type SILC_PACKET_FTP and defined File Transfer
1690 Payload. The mandatory file transfer protocol is SFTP
1691 (SSH File Transfer Protocol). Affected file in addition
1692 of the internet draft is lib/silccore/silcpacket.h.
1694 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1695 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1696 is used as part of backup router protocol when the primary
1697 router of the cell is back online and wishes to resume
1698 the position as primary router.
1700 * Redefined the MAC generation keys in the protocol. The
1701 same key is not used anymore in both direction. Both
1702 direction will now use different keys for sending and
1703 receiving. This fixes a potential security flaw. This
1704 change causes incompatibilities in the protocol.
1706 * Redefined also the MAC computation from the packet.
1707 An packet sequence number is now added to the MAC
1708 computation. This prevents possible replay attacks against
1709 the protocol. This change too causes incompatibilities
1712 Added `sequence' field to the SilcPacketContext to hold
1713 the current sequence number for the packet.
1715 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1717 * Added `created' field to the SilcIDListData in the file
1718 silcd/idlist.h to indicate the time when the entry was
1721 * Added `created' field to the SilcChannelEntry too. Affected
1722 file silcd/idlist.h.
1724 * Added `creation_time' aguments to all the announcement functions
1725 in the server. If it is provided then only the entries that
1726 was created after the provided time frame are actually
1727 announced. Affected file silcd/server.[ch].
1729 * The protocol says that the Channel ID's IP address must be
1730 based on the router's IP address. Added check for this in
1731 the silc_server_new_channel when processing incoming New Channel
1732 Payload. Affected file silcd/packet_receive.c.
1734 * Print out the correct version with --version in SILC client.
1735 Affected file irssi/src/silc/core/silc-core.c.
1737 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1739 * Fixed WHOWAS command to check for completnes of the client
1740 entry always, not just when the command is coming from client.
1741 Affected file silcd/command.c.
1743 * Added new function silc_server_packet_queue_purge to purge the
1744 outgoing data queue to the network. After the function returns
1745 it is guaranteed that the outgoing packet queue is empty.
1746 Affected file silcd/packet_send.[ch].
1748 * Purge the outgoing packet queue in the rekey protocol's final
1749 callback to assure that all rekey packets go to the network
1750 before quitting the protocol. Affected file silcd/server.c.
1752 * Added silc_client_packet_queue_parse as similar function as
1753 in server to the client library. The affected file is
1754 lib/silcclient/client.c.
1756 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1758 * Splitted silcd/server.c and created silcd/server_util.[ch]
1759 for utility functions.
1761 * Added new socket flag SILC_SF_DISABLED to indicate that the
1762 connection is open but nothing can be sent to or received from
1763 the connection. Affected file lib/silcutil/silsockconn.[ch].
1764 The checking for disabled socket is checked in the low level
1765 silc_socket_write and silc_socket_read functions.
1767 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1769 * Allow only nicknames and channel names that fits into the
1770 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1772 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1774 * When processing JOIN command reply in server check that if
1775 the channel exists in our global list we'll move it the local
1776 list. Affected file silcd/command_reply.c.
1778 * Fixed the check whether client is joined on the channel already
1779 in JOIN command. Affected file lib/silcclient/command.c.
1781 * Fixed the JOIN command reply to check whether the channel
1782 already exists. Affected file lib/silcclient/command_reply.c.
1784 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1786 * Added silc_ske_status_string to map the SKE error numbers
1787 to readable strings. The affected files are
1788 lib/silcske/silcske[_status].[ch].
1790 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1792 * Do not show the private channels on the WHOIS channel list
1793 as it is not allowed by the protocol. The affected file is
1796 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1798 * Assure that the packet length digged from the actual packet
1799 is something sensible in the silc_packet_decrypt_rest_special
1800 in lib/silccrypt/silcpacket.c.
1802 * Free and NULL the allocated pointer in silc_hmac_alloc if
1803 the HMAC allocation fails. The affected file is
1804 lib/silccrypt/silchmac.c.
1806 * Print the selected security properties to the log files in
1807 the server. Affected file silcd/protocol.c.
1809 * Add SKE's reference counter even if calling the completion
1810 callback manually. Otherwise it goes negative, although it
1811 does not cause any problems. The affected file is
1812 lib/silcske/silcske.c.
1814 * Remove the client entry with short timeout after giving the
1815 KILL command. Affected file lib/silcclient/command.c.
1817 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1818 case all found clients are already disconnected (WHOWAS would
1819 found them) in the server. Affected file silcd/command.c.
1821 * Update the last_receive (time of last data received) to be
1822 updated only when received private or channel message so that
1823 the idle time showed in WHOIS makes more sense.
1825 * Added boolean field `valid' in to the SilcClientEntry in the
1826 client library to indicate whether the entry is valid or not.
1827 This fixes the nickname change bug on channel when changing
1828 the nickname to be same than the old (like nick to Nick) the
1829 nickname formatter doesn't set the new nick anymore to Nick@host.
1830 Affected file lib/silcclient/idlist.[ch].
1832 * Now actually fixed the nickname changing on disconnection.
1833 Added new function silc_change_nick to the Irssi SILC Client.
1834 Affected file irssi/src/silc/core/client_ops.c,
1835 irssi/src/silc/core/silc-nicklist.[ch].
1837 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1839 * Check that the public key exists in the GETKEY command before
1840 trying to encode it. Affected file silcd/command.c.
1842 * Print some notifications on received public keys with GETKEY
1843 command in the Irssi SILC Client. Affected files are
1844 irssi/src/fe-common/silc/module-formats.[ch],
1845 irssi/src/silc/core/client_ops.c.
1847 * Use IDENTIFY command to resolve the server information in the
1848 GETKEY command instead of INFO command. Affected file
1849 lib/silcclient/command.c.
1851 * All command reply functions in the client library now calls
1852 the pending command reply callbacks even if an error has
1853 occurred. The server has done this a long time and now it was
1854 time to move the client library to this as well. Now all
1855 errors can be delivered back to the pending command reply
1856 callbacks if necessary. Affected files are
1857 lib/silcclient/command[_reply].[ch].
1859 * Change the nickname on disconnection back to the username
1860 because in reconnect the server will enforce it to it anyway.
1861 Affected file irssi/src/silc/core/silc-servers.c.
1863 * Fixed a config file parsing bug in the Irssi SILC client.
1864 Affected file irssi/src/silc/core/clientconfig.c.
1866 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1868 * When printing the channel mode on JOIN, verify that the
1869 channel key and channel's HMAC are valid. Affected file
1870 irssi/src/silc/core/client_ops.c.
1872 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1875 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1876 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1878 * Removed channel key rekey task deleting from the function
1879 silc_server_save_channel_key. Affected file silcd/server.c.
1880 Added explicit timeout task context instead that is used to
1881 delete the task if we are registering a new task before the
1882 new task has elapsed.
1884 * When channel key rekey occurs the client library now saves
1885 the old channel key for a short period of time (10 seconds) and
1886 is able to use it in case some is still sending channel
1887 messages encrypted with the old key after the rekey. Affected
1888 file lib/silcclient/[idlist.h|client_channel.c].
1890 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1892 * Added check to the silc_server_new_id_real to not accept
1893 new ID if it is the sender's own ID. Affected file is
1894 silcd/packet_receive.c.
1896 * Assure that we do not announce ourself or the one we've
1897 sending our announcements when we're router and are announcing
1898 servers to our primary router. Affected file silcd/server.c.
1900 * Fixed silc_server_command_identify_check_client to assemble
1901 correct WHOIS packet. It send corrupted WHOIS packet and
1902 caused problem with router to router connections. Affected
1903 file silcd/command.c.
1905 Fixed also silc_server_command_whois_check the same way
1906 as for the IDENTIFY command.
1908 * Added new SilcIDListStatus to the server in the SilcIDListData
1909 structure. The status now includes the current status of
1910 the entry (like registered, resolved etc.). Affected file
1911 silcd/idlist.[ch]. Defined a bunch of different status types
1912 as well. This replaced the old boolean registered field as well.
1914 Added resolve_cmd_ident field to the SilcClientEntry structure
1915 too so that if the entry is for example being resolved so
1916 another command may attach to the same pending command reply
1917 without requiring to resolve the same entry again. This concept
1918 should optimize the WHOIS and the IDENTIFY resolving under
1919 heavy load by taking away unnecessary resolving for entries
1920 that are being resolved already.
1922 Added support for adding multiple pending commands for one
1923 command idenfier. Affected file silcd/command[_reply].[ch].
1925 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1926 before deleting the data. Otherwise the hash table will have
1927 freed data in comparison functions. Affected file is
1928 silcd/command_reply.c.
1930 * Fixed silc_idlist_replace_client_id to add the new entry to
1931 the cache with NULL nickname. Otherwise there will be invalid
1932 memory as the nickname after the nickname is freed. Affected
1933 file silcd/packet_receive.c.
1935 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1936 saved into wrong slots because the previous number of entries
1937 was not taken into account. Affected file silcd/idlist.c.
1938 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1940 * If we are router and we receive JOIN notify to a channel that
1941 does not have any users then notified client is marked as the
1942 channel founder, as it is it. The affected file is
1943 silcd/packet_receive.c
1945 * Added to the extended hash table API's table_del_*ext functions
1946 the destructor as argument too, so that the caller can decide
1947 which destructor to use or whether to use destructor at all.
1948 Affected file lib/silcutil/silchashtable.[ch].
1950 * Fixed ID Cache purging. It actually deleted the entries from
1951 the hash table after the data was freed. The hash table ended
1952 up comparing freed memory. The affected file is
1953 lib/silccore/silcidcache.c.
1955 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1957 * Fixed Irssi SILC client's KILL command's HELP syntax.
1959 * The USERS command now resolves the detailed user information
1960 if the userinfo field is missing. Affected file is
1961 lib/silcclient/command_reply.c.
1963 * Do not print error in silc_file_read if the read file does
1964 not exist. Just silently return NULL. Affected file is
1965 lib/silcutil/silcutil.c.
1967 * Fixed the silc_log_output to not wine about NULL filename
1968 and to not create some bogus " " filename. Affected file is
1969 lib/silcutil/silclog.c.
1971 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * Fixed various printing bugs on the user interface in the
1974 Irssi SILC Client. Minor changes that were forgotten from
1977 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1979 * Fixed the configure.in.pre and the compilation and distribution
1980 environment to support the new autoconf 2.52. That version is
1981 now required to compile the CVS trunk.
1983 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1985 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1986 to generally parse user@fqdn format strings. Affected file
1987 lib/silcutil/silcutil.c.
1989 * Added nickname_format and nickname_force_format fields to the
1990 SilcClientParams structure. The first one defines the format
1991 for the nicknames that the library will enforce if the receives
1992 multiple same nicknames. The second one is boolean value and
1993 can be used to force the library to always enforce the format
1994 to the nicknames regardles whether there are multiple nicknames
1995 or not. This configurable formatting was employed to flexibly
1996 support accessing multiple nicknames from the user interface.
1997 The userinterface can now set the nicknames to what ever format
1998 they prefer. Affected file lib/silcclient/silcapi.h.
2000 Added function silc_client_nickname_format to the file
2001 lib/silcclient/idlist.c. It performs the nickname formatting.
2003 Added new field `hostname´ to the SilcClientEntry context.
2004 It holds the hostname of the client. Affected file is
2005 lib/silcclient/idlist.h.
2007 * Irssi SILC Client sets the nicknames in nick@hostn format.
2008 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2009 irssi/src/silc/core/silc-core.c.
2011 The WHOIS printing now also shows both the real nickname and
2012 the formatted nickname so that user knows how to access the
2013 user if there are multiple same nicknames cached. Affected
2014 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2015 printing formatting too to take the hostname now as a separate
2016 argument. The Affected file is
2017 irssi/src/fe-common/silc/modules-formats.[ch].
2019 * Changed the silc_client_get_clients_local to accept the formatted
2020 nickname as argument. It accepts the real nickname too but the
2021 formatted nickname can be used to find the true entry from
2022 multiple entries. Affected file lib/silcclient/silcapi.h and
2023 lib/silcclient/idlist.c.
2025 * Added nickname_format_parse field to the SilcClientParams.
2026 It is a callback function provided by the application to parse
2027 the nickname out of the formatted nickname string. The library
2028 calls it to get the nickname from the formatted string. Since
2029 the application generally knows better the format of the nickname
2030 string it parses it instead of the library, even though library
2031 encodes the formatted string. If the callback function is not
2032 provided then the library will use the string as is. The
2033 affected file is lib/silcclient/silcapi.h.
2035 * All the nickname strings passed to the client library in
2036 commands are now expected to be formatted nickname strings.
2037 If the command does not support the formatted nickname string
2038 it will assume that the sent string is the actual nickname.
2039 Affected file lib/silcclient/command.c.
2041 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2043 * Added public key authentication support to OPER and SILCOPER
2044 commands in the client library. Affected file is
2045 lib/silcclient/command.c.
2047 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2049 * Changed the get_auth_methdod client operation to be asynchronous.
2050 It can be async if the application resolves the authentication
2051 method from the server during the negotiation. Added new
2052 SilcGetAuthMeth completion callback that the application will
2053 call after resolving the authentication method.
2055 Added function silc_client_request_authentication_method that
2056 the application can use to resolve the authentication method
2057 from the server. Added also SilcConnectionAuthRequest callback
2058 that the library will call after the server has replied. The
2059 application can call this function if it does not know the
2060 current authentication method.
2062 Affected files are lib/silcclient/client.c and
2063 lib/silcclient/silcapi.h.
2065 * The Irssi SILC client now automatically resolves the authentication
2066 method incase any configuration information is not present (and
2067 currently there never is). The affected file is
2068 irssi/src/silc/core/client_ops.c.
2070 * Fixed public key authentication from the client library.
2071 Affected file lib/silcclient/protocol.c. Changed also the
2072 protocol specification about the public key authentication in
2073 the connection authentication protocol. The actual data to be
2074 signed is now computed with a hash function before signing.
2076 * Fixed the public key authentication from the server as well.
2077 Affected file silcd/protocol.c.
2079 * Removed the mlock()'s from the memory allocation routines.
2080 Affected file lib/silcutil/silcmemory.c. The ./configure does
2081 not check anymore for the mlock(). Affected file is
2084 * Fixed USERS command in server to allow the execution of the
2085 command for private and secret channels if the client sending
2086 the command is on the channel. Affected file silcd/command.c.
2088 * Fixed silc_client_get_clients_local to return the clients
2089 count correctly. It could return wrong value. Affected file
2090 lib/silcclient/idlist.c.
2092 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2094 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2095 types. The assembler optimizations seemed not to like 64-bit
2096 data types. The assmebler optimizations thus are now enabled
2097 also for BSD systems as opposed to only enable them for Linux.
2099 * Do not check for threads at all on BSD systems. Affected
2100 file configure.in.pre.
2102 * Removed -n and -h options from the Irssi SILC Client since
2103 they are not used in silc.
2105 * Fixed the prime generation to assure that the first digit
2106 of the generated random number is not zero since our conversion
2107 routines does not like number strings that starts with zero
2108 digit. If zero digit is seen the random number is regenerated.
2109 This caused some corrupted RSA keys when the zero first digit
2110 was met. Affected file lib/silcmath/silcprimegen.c.
2112 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2114 * Fixed WIN32 configuration in the ./configure script.
2115 Fixed to include xti.h on environments that has it.
2116 Patches by Carsten Ilchmann and andrew.
2118 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2120 * Changed the silc_id_create_client_id to be collision
2121 resistant. It is now assured that there cannot be created
2122 two same client ID's. I suspect that some weird bugs in
2123 the server were actually caused by duplicate Client IDs.
2124 Affected file silcd/serverid.[ch]. A router receiving
2125 new ID now also assures and informs the sending server
2126 if the ID caused collision.
2128 * Changed the silc_id_create_channel_id to also assure that
2129 there are no collisions.
2131 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2133 * Statement about ignoring the Mutual Authentication flag when
2134 performing rekey with PFS was a bit misleading. It is ignored
2135 if it was set in the initial negotiation, it cannot be even
2136 set in the rekey. Fixed in the ke-auth draft. Started the
2137 new versions of the protocol drafts in the doc/.
2139 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2141 * Fixed a bug in silc_client_command_identify_save when saving
2142 new channel information. The channel name was no duplicated
2143 and caused crash on exit. Affected file is
2144 lib/silcclient/command_reply.c.
2146 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2148 * Fixed the getkey command handling in the server. Send just
2149 empty OK reply to the sender if the key could not be fetched
2150 (but everything else was ok, like the key just was not available).
2151 Changed the public key parameter to optional in the protocol
2152 specs so that empty OK reply can be sent. Affected file
2155 Added a message to Irssi SILC client to tell to user if the
2156 server did not return a public key.
2158 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2160 * Fixed a channel key regeneration bug. It registered new
2161 timeout tasks exponentially until all system resources were
2162 used. Affected file silcd/server.c.
2164 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2166 * Added the SILC Document generator to the scripts/silcdoc.
2167 It can be used to generate the Toolkit Reference Manual out
2168 of the source tree. Internally it will also use the RoboDoc
2169 generator now imported in util/robodoc.
2171 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2173 * Added couple of return's in rekey protocol if error orccurred
2174 during the protocol. The execution must be terminated.
2175 Affected file silcd/protocol.c. Also, terminate the protocol
2176 always with timeout.
2178 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2180 * The client's Client ID was created initally from the wrong
2181 nickname (it could have been in format nick@host) in the
2182 silc_server_new_client. Affected file silcd/packet_receive.c
2184 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2186 * Added some SILC_LOG_ERROR's to various error conditions
2187 if client could not be added to ID cache. Affected files
2188 silcd/packet_receive.c and silcd/server.c.
2190 * When client's sock->user_data is freed, NULL also the
2191 client->router and client->connection pointers. Added check
2192 for these pointers being NULL to various places around the
2193 code. Affected file silcd/server.c.
2195 * Added client->data.registered == TRUE checks to various
2196 places around the code to assure that unregistered client's
2197 are not handled when it is not allowed. Affected file
2200 * Added `bool registered' fields to all
2201 silc_idlist_[server|client]_get_* routines to indicate whether
2202 the fetched client needs to be registered or not. Affected
2203 file silcd/idlist.[ch].
2205 * Add your own entry as registered to the ID cache in the
2206 server. Affected file server.c.
2208 * Fixed a bug in silc_server_new_server. The SilcServer was
2209 set as the new server's context instead of SilcServerEntry.
2210 This naturally caused some weird bugs.
2212 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2214 * Do not delete the channel rekey task when adding it
2215 for in silc_server_create_channel_key.
2217 * Changed the silc_server_create_channel_key to return
2218 TRUE or FALSE to indicate the success of the channel key
2221 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2223 * Fixed MSVC++ project files and added missing files to
2224 Makefiles under win32/.
2226 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2228 * Do not add TCP_NODELAY flag if the operating system
2229 does not have it defined. Affected files are
2230 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2232 * Fixed buffer overflow from Irssi SILC Client. Affected
2233 file irssi/src/fe-common/core/themes.c.
2235 * Fixed double free in client library in the file
2236 lib/silcclient/client.c when disconnecting from server.
2238 * Applied double free patch from cras to Irssi SILC client.
2239 Affected files irssi/src/core/[modules/expandos].c
2241 * Fixed the disconnection handling to Irssi SILC Client.
2242 The application must call silc_client_close_connection
2243 in ops->connect client operation in case of failure of
2244 the connection. Affected file is
2245 irssi/src/silc/core/client_ops.c.
2247 * Do not set sock->protocol to NULL in the function
2248 silc_client_close_connection after executing the protocol's
2249 final callback since the sock might not be valid anymore.
2250 Affected file lib/silcclient/client.c.
2252 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2254 * Do not enable SILC_THREADS if the linking with libpthread
2255 did not happen. Affected file configure.in.pre.
2257 * Added notion to protocol specification that server must
2258 verify the sent authentication payload with CMODE when
2259 setting the channel founder key. Implemented it to the
2260 server. Affected file silcd/command.c.
2262 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2264 * Added _EXTRA_DIST SILC distribution variable to the
2265 distributions file. It is used to conditionally add extra
2266 files or directories to the specific distribution. Affected
2267 files ./prepare, Makefile.am.pre and distributions.
2269 Removed the `_' from the start of the distribution names.
2272 * Added README.WIN32 for instructions to compile the Toolkit
2275 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2277 * Fixed a double free in disconnection in the server. Affected
2278 file is silcd/server.c.
2280 * Fixed the lib/silcske/groups.c to work now also with GMP
2281 MP library. The string conversion did not work when using
2282 specific base and the base is indicated in the string as well.
2284 * Created win32/ directory which now includes MSVC++ specific
2285 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2286 It will appear only in the toolkit distribution
2288 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2290 * Changed the key material distribution function in case when
2291 the hash output is too short. The data is now concatenated
2292 a bit differently than it used to. Made the change to the
2293 SKE protocol specification.
2295 * Added better GMP detection to configure.in.pre. A patch
2298 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2300 * Fixed a minor bug in SKE that might cause some problem on
2301 some platforms. Affected file lib/silcske/silcske.c.
2303 * Added the cookie checking for initiator in the SKE. It checks
2304 that the responder returns the sent cookie unmodified. The
2305 affected file is lib/silcske/silcske.c. Added new SKE
2306 error type INVALID_COOKIE that can be sent during the
2307 negotiation. Fixed some memory leaks as well.
2309 * Added the "invalid cookie" error message to Irssi SILC client's
2312 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2314 * Added `task_max' field to the SilcClientParams to indicate
2315 the maximum tasks the scheduler can handle. If set to zero,
2316 default values are used. Affected file lib/silcclient/silcapi.h.
2318 * Fixed memory leaks in silc_client_close_connection. Affected
2319 file lib/silcclient/client.c.
2321 * Added silc_client_del_client_entry to client library to free
2322 all memory of given client entry. Affected file is
2323 lib/silcclient/idlist.[ch].
2325 * Added new functions silc_client_del_channel and
2326 silc_client_del_server to delete channel and server entries.
2327 Affected file lib/silcclient/[silcapi.h/idlist.c].
2329 * Removed silc_client_del_client_by_id from silcapi.h.
2331 * Fixed the INFO command to return the server's own info
2332 correctly when querying by Server ID. Affected file is
2335 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2337 * Removed the non-blocking settings in WIN32 code in the
2338 silc_sock_[read/write] and added SleepEx instead. Affected
2339 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2340 of input data is now checked with FIONREAD and ioctlsocket.
2342 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2344 * Call silc_schedule_task_del_by_context in the
2345 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2346 Affected file lib/silccore/silcprotocol.c.
2348 * Call silc_protocol_cancel for active protocols in the
2349 silc_server_close_connection if the funtion
2350 silc_server_free_sock_user_data has not been called.
2351 Affected file silcd/server.c.
2353 * Generic tasks cannot be deleted using the del_by_fd
2354 task deleting function since generic tasks does not match
2355 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2357 * Added a notion to SILCOPER help file that the SILCOPER works
2358 only on router server, not on normal server.
2360 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2362 * Added for WIN32 support for the new scheduler as well.
2363 Affected file lib/silcutil/win32/silcwin32schedule.c.
2365 * Fixed the SHA1 implementation to work on various platforms.
2367 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2370 API. It is part of the scheduler now. Everything else is
2371 as previously but some functions has changed their names.
2372 Checkout the lib/silcutil/silcschedule.h for the interface.
2373 Updated all applications to use the new interface. Affected
2374 files are lib/silcutil/silcschedule.[ch].
2376 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2378 * Found a bug in the SKE implementation. The HASH value,
2379 specified by the protocol, was not computed correctly. The
2380 public key of the responder was not added to the computation
2381 even though it is mandatory. Affected file lib/silcske/silcske.c.
2382 This unfortunately causes incompatibilities with older
2383 clients and servers.
2385 * Added WIN32 specific network init and uninit functions:
2386 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2387 the Winsock2. Affected file lib/silcutil/silcnet.h and
2388 lib/silcutil/win32/silcwin32net.c.
2390 * Set the socket always to nonblocking mode on WIN32 after
2391 reading data or writing data. Affected file is
2392 lib/silcutil/win32/silcwin32sockconn.c.
2394 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2396 * Fixed various compilation problems under WIN32. Affected
2397 files lib/silcutil/win32/silcwin32thread.c and
2398 lib/silcutil/win32/silcwin32schedule.c.
2400 * Removed all _internal.h #includes from public header
2401 files. Internal headers must never be included from
2404 Removed also the lib/silcske/payload_internal.h file.
2406 * All include files that may be needed (public and some others
2407 included by the public headers) by application developers are
2408 now copied to the ./includes directory. It does not copy any
2409 internal headers. Affected file Makefile.defines.pre and all
2410 Makefile.am's under lib/ and subdirs.
2412 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2414 * Do not change the ~/.silc directory's permissions automatically.
2415 Affected file irssi/src/silc/core/clientutil.c.
2417 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2419 * Do not cancel the protocol in silc_server_close_connection
2420 it might cause recursion. Now cancelled in the function
2421 silc_server_free_sock_user_data. Affected file silcd/server.c.
2423 * Fixed the silc_server_remove_clients_by_server to regenerate
2424 the channel keys correctly finally. Added also new function
2425 silc_server_remove_clients_channels to actually do it.
2426 Affected file silcd/server.c.
2428 * Fixed the silc_server_new_channel to not crash by giving
2429 wrong router to the new channel. Affected file is
2430 silcd/packet_receive.c.
2432 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2434 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2435 which is given as argument to the silc_client_alloc now.
2436 It can be used to configure the client and set various parameters
2437 that affect the function of the client.
2439 * The USERS command in server did not check whether the channel
2440 is private or secret. Affected file silcd/command.c.
2442 * Added new argument to the USERS command in protocol specification.
2443 The USERS command now can take the channel name as argument
2444 as well. Added support for this in client and server and
2445 updated the protocol specs.
2447 * Completed the GETKEY command in client. It can be now used
2448 to fetch also servers public key not only some clients.
2449 Affected files lib/silcclient/command[_reply].c.
2451 * Added silc_client_get_server to return server entry by the
2452 server name. Affected files lib/silcclient/silcapi.h and
2455 * Redefined the IDENTIFY command in protocol specification to be
2456 more generic. It now can be used to query information about
2457 any entity in the SILC Network, including clients, servers and
2458 channels. The query may be based either the entity's name
2459 or the ID. Added support for this in both client and server.
2461 Affected files silcd/command.c and lib/silcclient/command.c
2462 and command_reply.c.
2464 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2465 the _from_client and _from_server functions. Affected file
2468 * Added silc_client_get_channel_by_id_resolve to the file
2469 lib/silcclient/silcapi.h to resolve channel information by
2470 its ID. Added also silc_client_get_channel_by_id that
2471 does not resolve it from the server.
2473 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2475 * Added SilcServerEntry context into the client library
2476 to represent one server. The INFO command now allocates
2477 these to save the resolved server info. For now on the
2478 client library will also keep information about servers,
2479 connected and resolved with INFO.
2481 The INFO command now allocates the SilcServerEntry context
2482 and saves the server info there. The COMMAND_REPLY in
2483 the INFO now returns the parameters to application in
2484 same order as defined in the protocol specification.
2486 The entries are cached in the client->server_cache.
2488 * The INFO command is now issued after received the Client ID
2489 from the server. Affected file lib/silcclient/client.c.
2491 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2492 to the application as the mode changer might be server.
2493 It is guaranteed that NULL is not returned anymore to the
2494 application. Affected file lib/silcclient/client_notify.c.
2496 The ID Type is now also passed to the application so that
2497 it can check whether the returned entry is SilcClientEntry
2500 Added new function silc_client_get_server_by_id to return
2501 the server entry by ID. Affected files are the
2502 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2504 * Do not create the channel in the Irssi SILC Client when issuing
2505 the JOIN command but when received the sucessful JOIN command
2506 reply. Otherwise the channel might get created even though we
2507 could not join it. The Affected file is
2508 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2510 * Fixed a channel joining bug in router. The router must also
2511 check the channel modes, invite and ban lists etc. when serving
2512 the JOIN command sent by normal server. Affected file is
2513 silcd/command.c. The router now resolves the client's
2514 information from the server who sent the JOIN command if it
2515 does not know it, and processes the JOIN command only after
2518 * Changed the SilcCommandCb to take new argument; void *context2.
2519 Affected file lib/silccore/silccommand.h
2521 The second argument in the command callbacks in the server now
2522 includes the SilcServerCommandReplyContext if the command was
2523 called as pending command callback from the command reply.
2524 Otherwise it is NULL. When called as pending the status of the
2525 command reply will be checked and if it was erronous the
2526 error will be sent to the original sender of the command.
2527 This way the client always receives the error messages even
2528 though the server was actually the one who received the error
2529 when it resent the command to router, for example. Affected
2530 files silcd/command[_reply].[ch].
2532 * Fixed sending WHOWAS command's error message to client if
2533 the requested client could not be found. It was missing.
2536 * Changed the CMODE and CUMODE commands reply arguments in the
2537 protocol specification. The Channel ID is now sent in both
2538 of the commands to identify the channel. Implemented this
2539 new feature to the client and server. Affected files
2540 lib/silcclient/command_reply.c and silcd/command.c.
2542 * Made better checks for invite and ban lists in the JOIN
2543 command in server. Affected file silcd/command.c.
2545 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2547 * The server now performs the incoming host IP/DNS lookup
2548 using the silc_socket_host_lookup and thus does not block
2549 the server anymore. Affected file silcd/server.c.
2551 * Completed the multi-thread support for SILC Scheduler in
2552 the lib/silcutil/silcschedule.c.
2554 * Fixed the configure.in.pre to detect the pthread correctly
2557 * Fixed a deadlock in silc_task_queue_wakeup in the file
2558 lib/silcutil/silctask.c.
2560 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2562 * Added new function silc_schedule_wakeup that is used in
2563 multi-threaded environment to wakeup the main thread's
2564 schduler. It needs to be used when a thread adds a new task
2565 or removes a task from task queues. After waking up, the
2566 scheduler will detect the task queue changes. If threads
2567 support is not compiled in this function has no effect.
2568 Implemented the wakeup mechanism to both Unix and WIN32
2569 systems. Affected files are lib/silcutil/silcschedule.[ch],
2570 lib/silcutil/unix/silcunixschedule.c and the
2571 lib/silcutil/win32/silcwin32schedule.c.
2573 * Added new function silc_task_queue_wakeup to wakeup the
2574 scheduler by the specified task queue. Affected file
2575 lib/silcutil/silctask.[ch].
2577 * The silc_socket_host_lookup_start now wakes up the scheduler
2578 after adding the timeout task. Affected file is
2579 lib/silcutil/silcsockconn.c.
2581 * The silc_socket_host_lookup is synchronous now if the threads
2582 support is not compiled in. However, the callback is still
2583 called asyncronously through the scheduler, anyway. Affected
2584 file lib/silcutil/silcsockconn.c.
2586 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2588 * Added new function silc_socket_host_lookup to perform
2589 asynchronous IP and FQDN lookups for the socket connection.
2590 Affected files lib/silcutil/silcsockconn.[ch].
2592 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2594 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2595 that may or may not compile the mutex support in.
2597 Changed the silc_mutex_alloc interface. It allocates the
2598 mutex now to the sent pointer and returns TRUE or FALSE.
2600 Affected file lib/silcutil/silcmutex.h.
2602 * Wrote the SILC Task Queue interface to support multi-threads.
2603 Affected file lib/silcutil/silctask.[ch].
2605 * Wrote the SILC Scheduler to support multi-threads. Affected
2606 file lib/silcutil/silcschedule.c.
2608 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2610 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2611 in lib/silcutil/win32/.
2613 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2615 * Defined SILC Mutex API and SILC Thread API and implemented
2616 them for Unix. Affected files are
2617 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2618 lib/silcutil/unix/silcunixmutex.c and
2619 lib/silcutil/unix/silcunixthread.c.
2621 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2623 * Fixed the silc_server_remove_clients_by_server's channel
2624 key re-generation. The hash table handling was incorrect
2625 and would not work with many channels. Affected file is
2628 * Fixed some memory leaks around the server code.
2630 * Rewrote the silc_server_get_users_on_channel to support IPv6
2631 based Client ID's. Affected file silcd/server.c.
2633 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2634 specification. However, a separate document must be written
2635 to define the detailed signing procedure and the payload
2636 associated with the flag. Defined the flag to the
2637 lib/silccore/silcchannel.h as well.
2639 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2641 * Changed the dynamic tables to static size tables in the
2642 lib/silccrypt/silchmac.c.
2644 * Removed GCC dependencies from the code. A patch by cras.
2646 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2648 * Do not show the error "Error receiving packet bla bla"
2649 in server if it really was not an error (-2 means that reading
2650 is pending). Affected file silcd/server.c.
2652 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2654 * Fixed a possible crash in silc_server_remove_clients_by_server
2655 in silcd/server.c. Fixed there also some memory leaks.
2657 * Fixed the silc_idlist_replace_client_id. It could replace
2658 wrong key in the hash table. Affected file silcd/idlist.c.
2660 * Do not check whether there are global users on the channel
2661 if the channel->global_users is FALSE. Affected functions
2662 silc_server_remove_from_one_channel and
2663 silc_server_remove_from_channels in silcd/server.c. Also,
2664 do not check if the removed client is local as we can be
2665 sure that global client was not removed from the channel
2666 and checking for global users is not needed.
2668 * The silc_server_remove_clients_by_server now re-generates
2669 the channel keys correctly for those channels that had
2670 clients removed from them. Affected file silcd/server.c.
2672 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2674 * Found the reason of random crashes in the server. We weren't
2675 ignoring the SIGPIPE signal (which can be sent in write())
2676 and it crashed the server. Affected file silcd/silcd.c.
2678 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2680 * Assure that sock->user_data is not NULL in the function
2681 silc_server_packet_send in silcd/packet_send.c.
2683 * Disconnect the remote connection if it could not be added
2684 to any ID lists in the server. The affected file is
2687 * Check in silc_server_packet_send[_real/dest] that the
2688 socket is not disconnecting and ignore the data if it is.
2689 Affected file silcd/packet_send.c.
2691 * Define inline to __inline on native WIN32 compilation.
2692 Affected file includes/silcwin32.h.
2694 * Added some explicit type casts for inline code since MSVC
2695 require them. Affected files lib/silcutil/silcbuffer.h,
2696 lib/trq/silcdlist.h and lib/trq/silclist.h.
2698 * Print warning in log files from now on if the packet
2699 decryption fails. Affected file silcd/server.c.
2701 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2703 * Changed the `say' client operation's interface to accept
2704 new `type' argument to indicate the type of the message sent
2705 by the library. The application may filter the library's
2706 messages according the type. The affected file is the
2707 lib/silcclient/silcapi.h.
2709 * Added two new functions to lib/silcclient/silcapi.h:
2710 silc_client_del_client and silc_client_del_client_by_id.
2711 Affected file lib/silcclient/idlist.c.
2713 * Moved the clientincludes.h from includes/ to silc/ and
2714 serverincludes.h from includes/ to silcd/.
2716 * The modes for the CMODE and CUMODE are now passed as
2717 uint32 for application with COMMAND_REPLY. The affected
2718 file is lib/silcclient/command_reply.c.
2720 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2722 * /WHOIS without arguments shows client's own information.
2723 Affected file lib/silcclient/command.c.
2725 * Changed PING to not accept any arguments. The specs
2726 says that client can ping only the connected server so
2727 requiring an argument is not needed. Affected file is
2728 lib/silcclient/command.c.
2730 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2732 * Fixed a fatal bug in private message sending and reception
2733 encryption and decryption when using private message keys.
2734 The implementation was incorrect and did not follow the
2735 specification. It causd that some of the message were
2736 lost since it did not use the sending and receiving keys
2737 as the protocol suggests. This has been fixed and will cause
2738 incompatibilities with older clients when sending private
2739 message encrypted with private message keys. Affected files
2740 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2741 and various other in Irssi SILC Client.
2743 Added `responder' boolean argument to the functions
2744 silc_client_add_private_message_key[_ske] to indicate when
2745 the key is added as responder or initiator of the key
2748 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2750 * Removed the silc_ske_check_version function and created
2751 a SilcSKECheckVersion callback. Added also a function
2752 silc_ske_set_callbacks that is now used to set all SKE
2753 callbacks. The callback functions are not given to
2754 the SKE functions anymore, but this function is used to
2757 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2759 * Added `silc_version' argument to the silc_client_alloc
2760 to define the version of the application for the library.
2761 The library will use the version string to compare it
2762 against the remote host's (usually a server) version
2763 string. Affected file lib/silcclient/silcapi.h
2765 * Added the KE protocol context to Key Agreement context
2766 in client library so that we can abort the SKE if it
2767 is in process when we get timeout. Affected file is
2768 lib/silcclient/client_keyagr.c.
2770 * Do not resolve the client ID forever if it returns in the
2771 first time that such client does not exist. This was done
2772 for example with private message. Affected file is
2773 lib/silcclient/client_prvmsg.c.
2775 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2777 * Do not add regex.h for WIN32. The affected file
2778 includes/silcincludes.h.
2780 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2781 not work yet 100%. It generates the DLL's automatically
2782 when compiling with --with-win32 under cygwin.
2784 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2786 * lib/contrib/regex.c is not compiled on WIN32.
2788 * Added silc_net_get_socket_opt function to the
2789 lib/silcutil/silcnet.h.
2791 * Added includes/silcwin32.h for WIN32 specific includes
2794 * Do not use ptime structure or any of the posix process
2795 functions on WIN32 in lib/silccrypt/silrng.c.
2797 * Added silc_gettimeofday to provide generic function
2798 for struct timeval on all platforms. Added the function
2799 to lib/silcutil/silcutil.h.
2801 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2803 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2804 library as they clearly belong there. As a plus side we
2805 can make the actual socket connection routines platform
2808 Added also new generic function silc_socket_read and
2809 silc_socket_write (that used to be silc_packet_[read/write].
2810 The implementation of these are platform specific.
2812 * Added WIN32 specific routines of silc_socket_[read/write]
2813 to lib/silcutil/win32/silcwin32sockconn.c.
2815 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2817 * Added preliminary support for native WIN32 compilation under
2818 cygwin (using the -mno-cygwin option for GCC) to the
2819 ./configure.in.pre. The --with-win32 now prepares the
2820 compilation for native WIN32.
2822 * Rewrote the SILC Scheduler interface in the file
2823 lib/silcutil/silcschedule.h. The scheduler is now context
2824 based and does not have anymore any global static scheduler.
2825 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2826 and created lib/silcutil/win32 directory for WIN32 based
2829 * Added Unix specific network routines to the
2830 lib/silcutil/unix/silcunixnet.c and the old
2831 lib/silcutil/silcnet.c includes now only generic routines.
2833 Added WIN32 specific network routines to the
2834 lib/silcutil/win32/silcwin32net.c.
2836 * Added Unix specific utility functions from the
2837 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2839 * Added WIN32 SILC Scheduler to the file
2840 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2843 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2845 * Do not handle JOIN notify in the server if the target client
2846 is not registered (idata->registered == FALSE). The affected
2847 file is silcd/packet_receive.c.
2849 * Update the nickrec->founder in event_cumode in the Irssi SILC
2850 client. Affected file irssi/src/silc/core/silc-channels.c.
2852 * Fixed the CUMODE_CHANGE notify handling in the server when
2853 server and router are announcing their clients on channels.
2854 Now the mode changes are saved and notified correctly. The
2855 affected file is /silcd/packet_receive.c.
2857 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2858 They really did not replace the cache entry in the ID Cache.
2859 Now they do that. Affected file silcd/idlist.c.
2861 * Fixed the KICK notify handling in the Irssi SILC client to
2862 update the channel records so that the kicked client does not
2863 appear to be on the channel. The affected file is
2864 irssi/src/silc/core/silc-channels.c.
2866 * Always update the conn->current_channel when executing command
2867 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2869 * Fixed the KILL notify handling in Irssi SILC client to remove
2870 the killed client on all channels.
2872 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2874 * Fixed the silc_parse_command_line to remove extra spaces
2875 from the start and end of the arguments. Affected file is
2876 lib/silcutil/silcutil.c.
2878 * Cancel and free any active protocol in the function
2879 silc_server_close_connection. Affected file silcd/server.c.
2881 * Cancel and free any active protocol in the function
2882 silc_client_close_connction. Affected file is
2883 lib/silcclient/client.c.
2885 * Do not execute the KILL command for clients that are in
2886 history (ie. they are not in the network). Affected file is
2889 * Fixed KILL notify handling, client does not crash anymore.
2890 Affected file irssi/src/silc/core/silc-channels.c.
2892 * Reduced the default packet buffer size from 2048 to 1024 in
2893 lib/silccore/silcpacket.c.
2895 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2896 counter to the SKE context that is incresed when the SKE library
2897 performs async operation outside the library. If the outside
2898 process frees the SKE context and FREED status will be set
2899 and the library will detect after the sync operation that the
2900 libary is freed. The affected files are
2901 lib/silcske/silcske[_status].[ch].
2903 * Resolve the client entry information in the function
2904 silc_client_channel_message to assure that NULL pointer is not
2905 passed as client entry to the application. */
2907 * Fixed the task timeout calculation to assure that there is
2908 never negative timeouts. The affected file is
2909 lib/silcutil/silcschedule.c.
2911 * Fixed the channel user mode notification sending in server.
2912 It was sent point-to-point to the router (or to server by router)
2913 but it needs to be destined to a channel. The routines now
2914 supports sending the channel user mode notifys to the channels
2915 when announcing clients and channels. Affected files are
2916 silcd/server.c and silcd/packet_receive.c.
2918 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2919 It did not actually replace the old channel entry in the cache.
2920 Affected file lib/silcclient/client_notify.c.
2922 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2924 * Fixed a possible crash in silc_packet_send_prepare. It now
2925 assures always that there is enough space in the buffer and
2926 at the tail area of the buffer (for MAC).
2928 Fixed the inbound buffer reallocation in silc_packet_read.
2929 It was old code and did not handle the reallocation correctly.
2932 The affected file is lib/silccore/silcpacket.c.
2934 * Fixed buffer overflow in silc_parse_nickname in the file
2935 lib/silcutil/silcutil.c.
2937 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2939 * make install generates new server keys only if there is not
2942 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2944 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2945 Added check that if the NOREPLY is set then we will not send
2946 the away message. This avoids infinite loop of away messages
2947 if both clients are away. The affected file is
2948 lib/silcclient/client_prvmsg.c.
2950 * Fixed client crash if /NICK was given without arguments.
2951 Affected file lib/silcclient/command.c.
2953 * Server does not send the invite list in INVITE command back
2954 to the client if the list was not altered. Added this notion
2955 to the protocol spec as well. Affected file silcd/command.c.
2957 Fixed possible crash in INVITE command by checking the
2958 value of silc_server_get_client_route command.
2960 * Fixed the INVITE notify type handling. The arguments are now
2961 taken in correct order and client does not crash. The affected
2962 file is irssi/src/silc/core/silc-channels.c.
2964 Removed the "Inviting xxx to channel" message from the
2965 client library away and let the application handle it.
2966 Affected file lib/silcclient/command.c. Added that message
2967 to Irssi SILC client's message formats.
2969 * Fixed CMODE command crash in client. It now checks the
2970 amount of arguments correctly and does not crash. The affected
2971 file is lib/silcclient/command.c.
2973 * Do not create new channel automatically in silc_channels_join
2974 but check whether the channel by that name already exists.
2975 Affected file irssi/silc/core/silc-channels.c.
2977 * Do not send the SERVER_SIGNOFF to router if the disconnected
2978 entity was the router. Affected file silcd/server.c.
2980 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2981 SILC client as it was missing from there.
2983 Added the handling of the KICK notify to the Irssi SILC client
2984 as it was missing. Added "you have been kicked" message to
2985 Irssi SILC client's message modules formats.
2987 Added the handing of the KILL notify to the Irssi SILC client
2988 as it was missing. Added the kill message module formats
2991 The affected file is irssi/src/silc/core/silc-channels.c.
2993 * The router did not save the channel mode the server announced.
2994 Affected file silcd/packet_receive.c.
2996 * Fixed a possible crash in INFO command in server. If the
2997 server did not provide the server info it crashed. Affected
2998 file silcd/command.c.
3000 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3002 * Fixed the GETKEY command in the server to check also the
3003 global list. Otherwise the GETKEY would not work correctly
3004 in normal SILC server. Affected file silcd/command.c.
3006 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3008 * Fixed GETKEY crash, it crashed if the command did not succseed.
3010 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3012 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3013 is now real and not just an macro interface to GMP.
3015 Removed the entire GMP from the source tree and imported new
3016 NSS MPI library instead. Reason for removing GMP is that it is
3017 extremely large and compiles extremely slow. The NSS MPI
3018 is only a few files and compiles in less than 10 seconds.
3019 The speed is also about the same as GMP. The MPI is imported
3020 to lib/silcmath/mpi.
3022 If the system has GMP installed we will still use the GMP.
3023 If it is not then the NSS MPI will be compiled.
3025 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3027 * Merged a long nickname (127 characters long) crash bugfix from
3028 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3030 * Merged a freed memory reference bugfix from Irssi CVS tree.
3031 Affected file irssi/src/core/commands.c.
3033 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3035 * Added the server's public key sving and verification to the
3036 server when performing the SKE. This was missing and the
3037 remote server's (or router's) public key was accepted without
3038 checking whether we have it previously or trust it at all.
3039 Affected file silcd/protocol.c.
3041 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3043 * Check in the silc_server_timeout_remote if protocol is active
3044 and make sure that the protocol's final callback is called so
3045 that all memory if freed. Affected file silcd/server.c.
3047 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3049 * silc_server_whois_send_reply crashed the server if the nickname
3050 was 127 characters long. Affected file silcd/command.c.
3052 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3054 * Added sanity check to the silc_server_new_client. If the hostname
3055 is provided inside username then check that the provided hostname
3056 really is the same as the resolved one. If the hostname was not
3057 resolved then check it from the public key. Affected file is
3058 silcd/packet_receive.c.
3060 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3061 if the server disconnected us and the connection is not valid
3062 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3064 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3065 the library to the lib/silcutil/silcutil.[ch].
3067 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3069 * Close log file after open. Affected file
3070 lib/silcutil/silclog.c.
3072 * Check whether sock == NULL in silc_client_send_packet and return
3073 if it is. Affected file lib/silcclient/silcclient.c.
3075 * Check rec->entry == NULL in the Irssi SILC Client before
3076 sending the channel message. Affecte file is
3077 irssi/src/silc/core/silc-servers.c.
3079 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3081 * Merged a splitted window bugfix from Irssi CVS tree. The
3082 affected file is irssi/src/fe-text/textbuffer-view.c.
3084 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3085 It did not print nickname.
3087 * Improved the distributions system a bit.
3089 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3091 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3092 irssi/src/fe-text/gui-window.c.
3094 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3095 to in-active server. The affected file is
3096 irssi/src/silc/core/client_ops.c.
3098 * Resolve the client in USERS command reply if the entry does
3099 not have username resolved. The affected file is
3100 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3101 command to WHOIS command to really resolve stuff. The USERS
3102 is not used any more in any critical section so WHOIS can
3103 be used even though it might be slower than IDENTIFY.
3105 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3108 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3110 * Changed the protocol API a bit more consistent in the
3111 lib/silccore/silcprotocol.[ch].
3113 * Changed the following headers to ROBODoc format:
3115 lib/silccore/silcpayload.h
3116 lib/silccore/silcprotocol.h
3117 lib/silccore/silcsockconn.h
3119 All core library headers are now formatted.
3121 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3123 * Fixed a bug in Irssi SILC client; do not show that you are
3124 server/router operator if you really are not. Affected file is
3125 irssi/src/silc/core/client_ops.c.
3127 * Renamed silc_command_free_payload to silc_command_payload_free.
3128 Affected file lib/silccore/silccommand.h
3130 * Added silcmath.h to include the prototoypes of various routines
3131 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3134 * Changed the following headers to ROBODoc format:
3136 lib/silccore/silcchannel.h
3137 lib/silccore/silccommand.h
3138 lib/silccore/silcid.h
3139 lib/silccore/silcidcache.h
3140 lib/silccore/silcmode.h
3141 lib/silccore/silcnotify.h
3142 lib/silccore/silcpacket.h
3143 lib/silcmath/silcmath.h
3145 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3147 * Added checking to the server code not to start the server if
3148 ciphers and stuff are not configured properly. Affected files
3149 silcd/serverconfig.[h] and silcd/server.c.
3151 * Changed the layout of the header files of the public interfaces
3152 in the SILC libraries. The new layout supports ROBODoc
3153 documentation tool (and some others) so that it is easy to create
3154 a library reference manual. All the other headers and source
3155 code must still follow the CodingStyle document. Also source
3156 code must not include these ROBODoc stuffs, only the headers.
3157 Furthermore, all public interface headers must now be named
3158 by using `silc' prefix, example: silcapi.h, silccipher.h.
3159 Some files were renamed due to this. All the other headers
3160 must not be used as public interfaces. I will update the
3161 CodingStyle document later. Changed following headers, so far:
3163 lib/silcclient/silcapi.h
3164 lib/silccore/silcauth.h
3165 lib/silccore/silcprivate.h
3166 lib/silccrypt/silcdh.h
3168 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3172 * Removed silc_client_packet_send_flush from the client library
3173 as it is not needed. Affected file lib/silcclient/client.[ch].
3175 * Added printing of message of unresolved authentication method
3176 to the Irssi SILC client. Added it to the module formats.
3177 Removed the same message from the client library.
3179 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3181 * Added new distribution feature, DISTLABEL. Every distribution
3182 can define own preprocessor label that can be used in the
3183 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3184 file distributions, acconfig.h.pre and prepare.
3186 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3188 * Added Makefile.defines_int to include the actual definitions
3189 for Makefile.defines.in. Tested the new distribution system,
3190 created distributions and tested installation.
3192 * Added AWAY message printing to the Irssi SILC client. Added
3193 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3195 * Added SCONNECT command to call the SILC's CONNECT command.
3196 Cannot use CONNECT directly since Irssi uses that internally.
3197 Affected file irssi/src/silc/core/silc-servers.c.
3199 Added ACTION local command. It is same as ME command but takes
3200 the channel as mandatory argument.
3202 Rewrote some of the Irssi's help files to suite for SILC
3205 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3207 * Added Makefile.defines[.in] that should for now on be included
3208 in all Makefile.am file in the source tree. That file includes
3209 all common compilation definitions for SILC source tree.
3211 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3213 * Minor changes to the ./prepare script to change the package
3214 name according the distribution name to the configure.in.
3216 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3218 * Created new distribution system. Added file `distributions'
3219 that defines all the distributions that can be created out of
3220 the SILC source tree. The ./prepare script now reads that
3221 file to determine how to prepare the distributions. The
3222 first argument to the ./prepare is the name of the distribution
3223 and second is the version of the distribution. If given
3224 without arguments it creates the default (toolkit) distribution
3225 with the default version (defined in ./prepare).
3227 All Makefile.am files that are subject to the distributions
3228 are now named as Makefile.am.pre. These are ./Makefile.am
3229 and lib/Makefile.am. Others may be changed later.
3231 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3233 * Added invite list, ban list, some key management and connection
3234 error message printing to module formats in the Irssi SILC client.
3236 * Added new silc_client_set_away_message to set the away message
3237 that is back to the person who sent private message. The
3238 affected file lib/silcclient/silcapi.h and the
3239 lib/silcclient/client_prvmsg.c.
3241 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3243 * Fixed the private message sending in the Irssi SILC client,
3244 added local command KEY to the Irssi SILC client.
3246 Added key management and key agreement message formats to the
3247 irssi/src/fe-common/silc/module-formats.[ch].
3249 Added USERS (alias WHO) printing, server/router operator
3250 indication and LIST command printing to the module formats.
3252 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3254 * Fixed channel joining notify handling, cumode notify handling
3255 from Irssi SILC client.
3257 * Added SILC specific module-formats to the Irssi SILC client so
3258 that SILC specific message hilighting, colors etc is possible.
3259 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3261 Added channel mode, channel user mode, actions, notices,
3262 whois and whowas printing to the the module-formats.c.
3264 * Fixed a bug in channel deletion in the server. The channel
3265 is not left to the cache even if the channel founder auth mode
3266 is set when there are no users anymore on the channel. Affected
3267 file silcd/server.c.
3269 * The silc_net_localhost now resolves the entire hostname including
3270 the domain name. Affected file lib/silcutil/silcnet.c.
3272 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3274 * Changed the ask_passphrase client operation to be ascynchronous.
3275 It has now a completion callback and a context that the
3276 application must call after it has got the passphrase from
3277 the user. Affected files lib/silcclient/silcapi.h,
3278 lib/silcclient/protocol.c, lib/silcclient/command.c and
3281 Added SilcAskPassphrase callback that the application calls
3282 to deliver the passphrase to the library.
3284 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3285 The public key verification and especially a certificate
3286 verification is asynchronous procedure.
3288 Added new SILC_SKE_STATUS_PENDING status to indicate the
3289 request is pending and a callback will be called to finalize
3292 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3293 indicate that remote end did not send its public key (or
3294 certificate), even though we require it. Added check for this
3295 condition in the SKE. This was a security bug, now fixed.
3297 Defined new SilcSKEVerifyCbCompletion callback that is called
3298 when the verification process is completed.
3300 The affected files lib/silcske/silcske_status.h and
3301 lib/silcske/silcske.[ch].
3303 * Changed the verify_public_key client operation to be async
3304 as well. Defined SilcVerifyPublicKey callback that is used to
3305 indicate the success of the public key verification process.
3307 Changed the server and client to use the new async client
3310 * Changed the Irssi SILC client's internal scheduler to be called
3311 twice as many times as it used to be. As a result the client
3312 should be a bit faster now. Affected file is
3313 irssi/src/silc/core/silc-core.c.
3315 * Added support to Irssi SILC client of asynchronous public key
3316 verification and passphrase inquiry. Affected file is
3317 irssi/src/silc/core/silc-core.c.
3319 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3321 * Do not say "You have left channel %s" in client library.
3322 Moved it to the application. Affected files are
3323 lib/silcclient/command.c and silc/client_ops.c.
3325 * Fixed silc_client_get_clients. Command context was not
3326 duplicated and was freed memory in the callback. Affected
3327 file lib/silcclient/idlist.c.
3329 * Do not say "you are now talking..." on JOIN command in the
3330 client library. The appliation must handle it.
3332 * Do not say ".. changed topic to" in command reply in the
3333 client libary. The application must handle it.
3335 * Fixed TOPIC command sending in the client library.
3337 * Fixed a memory leak in silc_client_command_free in the file
3338 lib/silcclient/command.c.
3340 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * Imported a modified version of Irssi client to the source tree.
3343 The Irssi will be used to create a new client called
3344 Irssi SILC. Imported to irssi/.
3346 Added silc_core_init_finish function to the Irssi. Affected
3347 file irssi/configure.in.
3349 A lot changes in the Makefile.ams around the irssi tree.
3351 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3353 * Do not rehash if the new size is same as the old size of the
3354 hash table, in the silc_hash_table_rehash*. The affected file
3355 lib/silcutil/silchashtable.c.
3357 * Replaced hash_table_del_by_context calls from the server
3358 (when channel->user_list and client->channels) to the
3359 hash_table_del as it is sufficient and faster.
3361 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3363 * Added silc_hash_table_list, silc_hash_table_get and the
3364 SilcHashTableList structure to provide an alternative way to
3365 traverse the hash table. The affected files are
3366 lib/silcutil/silchashtable.[ch].
3368 * Changed the server's idlist routines to use the hash table
3369 routines to optimize the code.
3371 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3373 * Replaced the client entry's `channel' list and channel entry's
3374 `user_list' list to hash tables for optimized lookup. Changed
3375 the code to use the hash table interface around the code.
3376 Affected file lib/silcd/idlist.[ch].
3378 * Added `auto_rehash' boolean argument to the function
3379 silc_hash_table_alloc to indicate whether the hash table should
3380 auto-rehash when it thinks is appropriate time. It will
3381 increase the hash table size if the there is twice as much
3382 entries in the table than the size of the table, and will
3383 decrease the size if there are twice as less entries than
3384 the size of the table.
3386 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3388 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3390 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3392 * silc_idcache_purge_by_context deletes the entry now by context
3393 as it is supposed to do. Affected file lib/silccore/idcache.c.
3395 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3396 client is not anymore valid (WHOWAS givens the info) and not
3397 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3399 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3401 * Removed the `data' and `data_len' arguments from the ID Cache
3402 interfaces and added `name' argument. ID Cache does not handle
3403 anymore the binary data only a names associated with given ID.
3405 * When hashing a Client ID with silc_hash_id the entire ID is
3406 not hashed anymore, instead only the hash of the Client ID is
3407 hashed. This way we can access the Client ID from the cache
3408 with Client ID but with the hash of the ID (which is a hash of
3409 the nickname) as well without any difference in performance.
3411 Added also silc_idcache_find_by_id_one_ext to do one on one
3412 searching when we have the actual ID. Added also function
3413 silc_hash_client_id_compare. The affected files are
3414 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3416 * When hashing the name associated with a ID it is always done
3417 in lowercase. This way we can access the cache without worrying
3418 about case-sensitivity, even though, for example nicknames are
3421 * Fixed a bug in server with channel message sending. It put
3422 wrong ID type as destination ID. The affected file
3423 silcd/packet_send.c.
3425 * silc_idcache_del_by_context now deletes from all hash tables
3426 by context. Affected file lib/silccore/idcache.c.
3428 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * Changed the client library to use the new ID Cache interface.
3431 Changes around the source tree.
3433 * Added silc_hash_table_rehash_ext to rehash with specific
3434 hash function. Affected file lib/silcutil/silchashtable.[ch].
3436 * Added silc_hash_string_compare to compare two strings in the
3437 hash table. Affected file lib/silcutil/silcutil.[ch].
3439 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3441 * Added new function silc_idcache_del_by_context into the
3442 lib/silccore/idcache.[ch].
3444 * Changed the server's ID list routines to use the new ID Cache
3445 interface. Changes around the source tree.
3447 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3449 * Added silc_hash_table_del[_by_context]_ext functions in to the
3450 lib/silcutil/silchashtable.[ch].
3452 Removed silc_hash_table_find_all* routines and added new
3453 silc_hash_table_find_foreach to replace them.
3455 Added silc_hash_table_replace_ext function as extended
3456 replacing function. Separated the simple hash table interface
3457 from the extended hash table interface in the file
3458 lib/silcutil/silchashtable.h.
3460 * Fixed minor bugs and changed it to use some of the new
3461 hash table functions in lib/silccore/idcache.c
3463 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3465 * Added new function silc_hash_table_find_all to return all keys
3466 in the hash table by the specified key. As the hash table is
3467 collision resistant it also makes it possible to have several
3468 duplicate keys in the hash table. This function may be used to
3469 find all of the keys from the hash.
3471 Added user_context arguments to the SilcHashFunction,
3472 SilcHashCompare and SilcHashDestructor to deliver user specified
3475 Added new fuctions silc_hash_table_find[_all]_ext to do
3476 extended lookup with specified hash and compare functions and
3477 specified user contexts.
3479 Added new function silc_hash_table_add_ext to add the key
3480 with specified hash function and user context.
3482 Added new function silc_hash_table_foreach to traverse all
3483 entrys in the hash table. Added SilcHashForeach callback
3486 Added new function silc_hash_table_del_by_context to delete
3487 the entry only if the context associated with the key matches.
3489 Affected files are lib/silcutil/silchashtable.[ch].
3491 * Removed silc_hash_[server/client/channel]_id and added just
3492 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3493 silc_hash_id_compare to compare two ID's using as the hash table
3494 comparison function. Added also silc_hash_data to hash
3495 binary data and silc_hash_data_compare to compare it.
3497 * Removed silc_idlist_find_client_by_hash as it is not needed
3498 anymore. Affected file silcd/idlist.[ch].
3500 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3501 to use internally the SilcHashTable. The new ID Cache is a lot
3502 faster than the old one. Some of the ID Cache interface was also
3503 rewritten and obsolete and stupid functions were removed.
3505 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3507 * Added entry_count field to the SilcHashTable to keep the number
3508 of the entries in the table. Implemented the function
3509 silc_hash_table_rehash. Added new function
3510 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3512 Fixed a minor bug in silc_hash_table_free.
3514 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3515 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3516 into the lib/silcutil/silcutil.[ch].
3518 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3520 * Implemented a collision resistant hash table into the
3521 lib/silcutil/silchashtable[ch]. See the header and the source
3522 for the SilcHashTable API.
3524 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3526 * Merged dotconf version 1.0.2 into lib/dotconf.
3528 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3530 * Do not compile anything in lib/silcsim/* if the SIM support
3531 is not enabled. The tree should now compile without problems
3534 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3536 * Compiled the SILC under cygwin. Compiled and tested briefly
3537 without problems. More tests needed. The SIMs didn't compile
3540 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3542 * Fixed possible crash in silc_get_username in the
3543 lib/silcutil/silcutil.c.
3545 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * Fixed a va_arg in silc/client_ops.c.
3549 * Oops, RC5 routines were named AES and caused some problems
3550 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3552 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3554 * Added new SilcIDIP structure into the lib/silccore/id.h and
3555 replaced the old `ip' fields from all SILC ID's to that type.
3556 This is a step towards IPv6 support.
3558 The silc_id_get_len takes now the ID as an extra argument.
3559 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3560 both IPv4 and IPv6 based ID's.
3562 The affected files are lib/silccore/id.[ch] and other files
3563 around the tree using these routines.
3565 * Removed the ID length arguments in server from various
3566 silc_server_send_notify_* routines -> they are not needed
3569 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3571 * Fixed memory leak in silc_encode_pem_file in the file
3572 lib/silcutil/silcutil.c.
3574 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3576 * Check minor version as well in the SKE. Affected files are
3577 silcd/protocol.c and lib/silcclient/protocol.c.
3579 * Added --identifier option to the server so that an identifier
3580 can be when creating the public key for the server. Affected
3581 file is silcd/silcd.c.
3583 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3584 lib/silccrypt/silcpkcs.c.
3586 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3588 * Register default ciphers and stuff when using -C option with
3589 the server. Affected file sildc/silcd.c.
3591 * Put back the servers public key filename format, it is better
3592 than the new one. For now, the client keys are saved with the
3593 new filename format. The affected file silc/client_ops.c.
3595 * Implemented the Cipher API for the rest of the ciphers that
3596 did not implement it or implemented it the wrong way.
3598 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3600 * Register default ciphers and stuff when using the -S option
3601 in the client. Affected file silc/silc.c. Same also when
3602 creating new key pair with -C option.
3604 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3606 * Fixed the silc_verify_public_key client operation function to
3607 save the public keys differently. The fingerprint is now
3608 used as filename and not the hostname. This way also the
3609 client keys are saved uniquely and not with hostnames. The
3610 affected file is silc/client_ops.c.
3612 * Trimmed the silc_hash_fingerprint function to remove extra
3613 whitespaces from the end of the fingerprint. The affected
3614 file is lib/silccrypt/silchash.c.
3618 * Added silc_cipher_register_default function to register all
3619 default ciphers. It can be used when configuration files
3620 does not exist and the application does not want any specific
3621 ciphers in any specific order.
3623 The SilcDList is now used as silc_cipher_list dynamically
3624 allocated cipher list. Removed the static list all together
3625 and now all ciphers must be allocated to the dynamic list.
3626 The silc_cipher_alloc routine was changed to check only the
3629 All silc_cipher_* routines that used to return int returns
3632 The affected files lib/silccrypt/silccrypt.[ch].
3634 * The same thing was done to silc_hash_* as for silc_cipher_*
3635 routines. Affected files lib/silccrypt/silchash.[ch].
3637 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3638 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3639 Added also silc_pkcs_[un]register[_default] functions.
3640 Removed the data_context from the PKCS API.
3642 * Added silc_hmac_register_default function to register default
3643 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3644 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3645 to unregister all hmacs at once.
3647 * Register the default ciphers, hash functions, PKCSs and HMACs
3648 if client's configuration file does not exist. The affected
3651 * The client did not load the hash functions from the SIM
3652 modules at all. Added support for this. Affected file is
3653 silc/clientconfig.c.
3655 * When decoding public key with silc_pkcs_public_key_decode, check
3656 the supported algorithm only if PKCS are registered. Affected
3657 file lib/silccrypt/silcpkcs.c. The same was done with the
3658 silc_pkcs_private_key_decode.
3660 * Fixed the SILC List routines to keep the list always in order.
3661 It used to change the list's order when traversing the list but
3662 not it preserves the order. Affected file lib/trq/silclist.h.
3664 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3666 * Added the client library to use the SilcSocketConnection's
3667 reference counter (by silc_socket_dup) to prevent the bug that
3668 the socket object may be freed underneath async operation.
3670 * The name resolv library checking fixes in the configure.in.pre.
3673 * Created new version of the protocol drafts for future
3674 development. The -03 drafts are the ones that will be changed
3675 in the trunk now and the -02 will remain as they are.
3677 * Send list of CUMODE notifys to the router when announcing
3678 the channel users to the router. Affected file silcd/server.c.
3679 If the router receiving channel founder CUMODE for a channel
3680 that already has channel founder it will send CUMODE notify
3681 to the sender to remove the channel founder rights from the
3682 announced client. Affected file silcd/packet_receive.c.
3684 * The CUMODE notify may now use Server ID as well as the entity
3685 who changes the mode. Updated protocool specs.
3687 * Updated INSTALL and README files.
3689 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3691 * New web pages in the http://silc.pspt.fi. The pages was
3696 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3698 * Implemented the [DenyConnectin] config section in the server.
3699 Added silc_server_config_denied_conn to check whether incoming
3700 connection is denied. Affected file silcd/serverconfig.[ch].
3702 * Do not check the ports when checking the incoming configuration
3703 data if the port is 0, meaning any. Affected file is
3704 silcd/serverconfig.c.
3706 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * Fixed buffer overflow in silc_string_compare in the file
3709 lib/silcutil/silcutil.c.
3711 * Fixed double free in silc_server_command_leave in the file
3714 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3716 * Fixed the version checking in the server. Affected file is
3719 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3721 * Fixed the configuration data fetching when accepting new
3722 connections in the server. Affected file silcd/server.c.
3724 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3726 * Added `sender_entry' argument to the function
3727 silc_server_packet_relay_to_channel so that we can check
3728 whether some destination actually belongs to the same route
3729 the sender belongs (ie, we must not resend the packet to the
3730 sender). Affected file silcd/packet_send.[ch].
3732 * Added `servername' field to the SilcClientEntry in the server
3733 to hold the name of the server where client is from. Affected
3734 file is silcd/idlist.h.
3736 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3738 * Moved the channel message encrypting in the router betwen
3739 router connections from silc_server_channel_message to the
3740 silc_server_packet_relay_to_channel since we want to check
3741 whether we have anybody channel before encrypting anything.
3742 Affected files silcd/packet_[receive/send].c.
3744 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3746 * Fixed the [AdminConnection] server config section to support
3747 multiple entries. Affected file silcd/serverconfig.c.
3749 * Added support into the server to check the validity of the
3750 incoming connection before executing any KE or authentication
3753 * The connection configuration is now saved to the KE and
3754 connection auth protocol contexts and not fetched anymore in
3755 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3757 * The local hosts listenning address and port is also resolved
3758 now when starting the server. We want to have the socket object
3759 to include the real address and port for the listener. Added
3760 new function silc_net_check_local_by_sock into the files
3761 lib/silcutil/silcnet.[ch].
3763 * Fixed a broadcast bug in server -> do not broadcast if we
3766 * Fixed a routing bug. Do not route broadcast packets ever.
3767 Broadcast packets must be processed always and not routed since
3768 they may be destined to some other host than yourself and thus
3769 would get routed without no good reason. Affected file is
3772 * Added function silc_server_config_is_primary_route to check
3773 whether primary router connection has been configured (a router
3774 configuration that we are initiating). If there is not, we
3775 will assume that there is only two routers in the SILC network
3776 and we will use the incoming router connection as our primary
3777 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3779 * Changed the order of the broadcasting. Broadcast _after_ the
3780 packet has been processed not before. Affected file is
3783 * Fixed a [ClientConnection] parsing bug. The port was never
3784 parsed correctly thus resulting to port 0. Affected file
3785 silcd/serverconfig.c.
3787 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3788 argument and did not set the broadcast packet flag. Affected
3789 file silcd/packet_send.c. Fixed same bug in the function
3790 silc_server_send_notify as well.
3792 * If we receive NEW_ID packet for our own ID in the server, ignore
3795 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3799 * Removed the nickname from the Private Message Payload.
3800 Updated the code and the protocol specs.
3802 * Updated protocol specs for submitting to the IETF.
3804 * Tweaked the Random Number Generator a bit. Affected file
3805 lib/silccrypt/silcrng.c. Exported a new function
3806 silc_rng_[global]_add_noise which can be used to add more
3809 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3811 * Do not parse packets with different timeout when protocol
3812 is active -> may cause problem with rekey. Affected file
3815 * When server receives signoff notify it must not create
3816 new channel key if the client is on any channels since the
3817 sender of the signoff notify will create it.
3819 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Added printing of error messages during SKE protocol from the
3822 failure packet sent by server during SKE. Affected file
3825 * Removed the client's failure_callback handling with timeout
3826 and handle it immediately when received.
3828 * The SKE library returned wrong type in SUCCESS and FAILURE
3829 packets. They must be 32 bit MSB not 16 bit MSB.
3831 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Ok, rewrote the logic of the re-key and now it seems to work.
3834 I tested it on high traffic with frequent re-keys without
3835 problems. Added hmac_receive (and renamed hmac to hmac_send)
3836 in SilcClientConnection in lib/silcclient/client.h and
3837 in SilcIDListData in silcd/idlist.h. Also, removed the
3838 SilcPacketParserContext's cipher and hmac fields as they are
3839 not needed anymore and actually caused some problems when
3840 the ciphers and hmac's changed underneath the packet parser.
3842 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3844 * If re-key protocol is active then process the incoming packets
3845 synchronously since we must assure that icoming packets encrypted
3846 with the old key is processed before the new keys is set to
3847 use. This is true other packets than for REKEY packets.
3848 Affected file silcd/server.c. The same was done to client library
3849 as well, affected file lib/silcclient/client.c.
3851 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3853 * Fixed bug in client and server to accept the force send if
3854 the packet is send from silc_[server/client]_packet_process
3855 function. Otherwise the packets are never delivered, oops.
3857 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3859 * Disable force sending of packets when REKEY protocol is active.
3860 We must assure that no packet is sent directly when rekey is
3861 performed. All packets must be sent through packet queue.
3862 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3863 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3864 function is silc_[server/client]_packet_send_real to check
3867 * Replaced the SIM paths from example config files to
3868 /usr/local/modules. Also, make install creates now
3869 /usr/local/silc/logs directory to hold all the SILC server
3872 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3874 * Made the configure.in.pre work on Solaris. Patch by salo.
3876 * Made all ciphers compatible with non-x86 machines. Defined
3877 CBC mode macros into lib/silccrypt/ciphers_def.h.
3879 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3881 * Fixed the make install.
3883 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3885 * When MAC computation fails the silc_packet_decrypt returned 0
3886 even though it was supposed to return -1. Fixed this. The
3887 affected file is lib/silccore/silcpacket.c.
3889 * Do not replace the config files in /etc/silc (in make install)
3890 if they already exist. Affected file ./Makefile.am.
3892 * Do not send re-key packets immediately but through packet queue.
3893 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3895 * Changed silc_net_check_host_by_sock to return FALSE if the
3896 IP/DNS could not be resolved. Though, it returns the IP address
3897 now even if it could not resolve it (but returns also FALSE).
3898 Affected file lib/silcutil/silcnet.[ch].
3900 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3902 * Added silc_pkcs_decode_identifier to decode the public key's
3903 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3904 Added also silc_pkcs_free_identifier. Added also new context
3905 SilcPublicKeyIdentifier.
3907 * Added -S option to the silc client. It is used to dump the
3908 contents of the specified public key file.
3910 * Changed the PKCS api to return the public key length when
3911 setting the public key.
3913 * Fixed a fatal bug in the public and private key file loading.
3914 Affected file lib/silccrypt/silcpkcs.c.
3916 * Execute the packet parsing for client with zero (0) timeout
3917 if the protocol is active. Affected file silcd/server.c.
3919 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3921 * Made the key generation options to the silcd program. Added
3922 -C option, equivalent to client's option.
3924 * Added new [ServerKeys] config section to the server. It
3925 configures the server's public and private key.
3927 * Defined generic Public Key Payload into the protocol
3928 specification to send specific type of public keys and
3931 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3932 public key or certificate.
3934 * Implemented the GETKEY command to the server and to the
3935 client library and on user interface.
3937 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3939 * Made preliminary `make install' work.
3941 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3943 * Added SilcServerRekey context into silcd/idlist.h.
3945 * Added the PFS support as defined in the specification to the
3946 SKE protocol. Affected files lib/silcske/*.c.
3948 * Added `ske_group' field to the SilcServerRekey context to hold
3949 the number of the SKE group that is used with PFS in re-key.
3950 Affected file silcd/idlist.h.
3952 * Added PFS re-key support to the server. Affected file is
3955 * Added silc_protocol_cancel to cancel execution of the next
3956 state of the protocol. Affected file is
3957 lib/silccore/silcprotocol.[ch].
3959 * Added the re-key support with and without PFS to the client
3960 library. Re-key is performed once in an hour, by default.
3962 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3963 Added silc_client_rekey_callback and silc_client_rekey_final.
3964 Affected files are lib/silcclient/protocol.[ch] and
3965 lib/silcclient/client.[ch].
3967 * Removed the `hmac_key' and `hmac_key_len' fields from the
3968 SilcClientConnection structure; not needed. Affected file is
3969 lib/silcclient/client.h.
3973 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3975 * Do not ask whether user wants to use the negotiated private key
3976 for private messages, just use it. Affected file is
3977 silc/local_command.c.
3979 * Added `send_enc_key' and `enc_key_len' fields to the
3980 SilcIDListData structure since they are needed in the re-key
3981 phase. Affected file is silcd/idlist.[ch].
3983 * Implemented the simple re-key protocol into the server.
3984 Affected files silcd/server.c and silcd/protocol.[ch]. The
3985 re-key will be performed once in an hour, by default.
3987 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3988 Added silc_server_rekey, silc_server_rekey_callback and
3989 silc_server_rekey_final.
3991 * Removed Tunneled flag from the protocol. Updated the code
3992 and the specifications.
3994 * Adde `pfs' field to the SilcIDListData to indicate whether
3995 the PFS is to be performed in the re-key. Affected file is
3998 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4000 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4001 int64 of at least the xintXX size. If void * is less that 4
4002 bytes uint32 * will be used. Defined bool as boolean.
4004 * Changed _ALL_ unsigned long and unsigned int to uint32,
4005 unsgined short to uint16 in the source tree.
4007 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4008 not handle clients that has entry->data.registered == FALSE.
4009 They are not in the network anymore. Affected file is
4012 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Implemented the sending of the SERVER_SIGNOFF notify in the
4015 server. Affected file is silcd/server.c.
4017 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4018 Added also silc_notify_payload_encode_args into the
4019 lib/silccore/silcnotify.[ch].
4021 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4022 Affected file silcd/packet_receive.c.
4024 * Implemented the SERVER_SIGNOFF notify handling in the client
4025 library. Affected file lib/silcclient/client_notify.c. Also,
4026 implemnted the printing of the SERVER_SIGNOFF info to the
4027 application. Affected file silc/client_ops.c.
4029 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4030 if the deleting was successful. Affected file silcd/idlist.[ch].
4032 * Added support for public key authentication in the connection
4033 authentication protocol in the client library. Affected file
4034 lib/silcclient/protocol.c.
4036 * Changed the server's silc_idlist_get_clients_by_* interface
4037 to support already allocated array so that new entries may be
4038 added to pre-allocated array. Affected file silcd/idlist.[ch].
4039 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4040 and command replies.
4042 * All command reply functions in the server now calls the
4043 pending command callback even if error occured. This way the
4044 error will be delivered to the client as well. Affected files
4045 silcd/command.c and silcd/command_reply.c.
4047 * Fixed INFO command to return local server's info if no server
4048 was provided. Affected file lib/silcclient/command.c.
4050 * Removed RESTART command for good. Updated the code and the
4053 * Rewrote parts of the task system. It is a bit simpler now.
4054 Removed unsued task priorities. The affected files are
4055 lib/silcutil/silctask.[ch].
4057 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4059 * Moved the USERS printing from the library to the application.
4060 Affected files lib/silcclient/command.c and silc/client_ops.c.
4062 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4066 * Added channel key re-key support. The re-key is perfomed
4067 only by the router and is done once in an hour. Added `rekey'
4068 field to the SilcChannelEntry in the server. Affected files
4069 silcd/server.c and silcd/idlist.h.
4071 * Added silc_task_unregister_by_context into the file
4072 lib/silcutil/silctask.[ch].
4074 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4076 * Added SILC_UMODE_GONE mode to indicate when the client is not
4077 present in the SILC network. Added also support to the local
4078 command AWAY that will set this mode. Added support of showing
4079 "xxx is gone" in WHOIS command. The USERS command shows the
4080 gone status as well.
4082 * Fixed setting server and router operator privileges in the
4083 server's UMODE command. Affected file silcd/command.c.
4085 * Merged the SKE KE1 and KE2 payloads into one payload. The
4086 new KE payload is equivalent to the old KE2 payload.
4088 Cleaned up the SKE Start Payload parsing. It now uses the
4089 simple buffer unformatting to do the parsing. A lot faster
4092 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4093 to the SKE that is used to indicate whether both of the SKE
4094 parties should perform authentication. By default only the
4095 responder performs authentication. By setting this flag also
4096 the initiator must do authentication. By default it is unset
4097 since in normal SKE case, client to server connection, only
4098 the responder should do authentication. When doing SKE between
4099 two clients both should perform authentication. Updated the
4100 code and the protocol specs.
4102 * A little fix to IDENTIFY command in the server. Search the
4103 client first by hash not nickname. Affected file is
4106 * Fixed the silc_client_close_connection to support closing
4107 the client to client connections wihtout deleting too much
4108 data. Affected file lib/silcclient/client.c.
4110 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4111 are received if protocol used to be active but is not anymore
4112 the application would crash due to NULL pointer dereference.
4113 Affected files silcd/server.c and lib/silcclient/client.c.
4115 * Added `hash' field to the SilcClientConnection to include
4116 the hash function negotiated in the SKE protocol.
4118 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4119 to set the channel founder authentication data. A client can
4120 claim the founder rights later by providing the authentication
4121 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4122 This way the channel founder can regain the channel founder
4123 privileges even it is left the channel. This works only on
4124 local server and the client must be connected to the same
4125 server to be able to regain the founder rights. Updated the
4126 protocol specs accordingly.
4128 Added support to the CMODE command in the client to set the
4129 founder auth data. Read the README to see how to set it.
4131 Added support to the CUMODE command to claim the founder
4132 rights. Read the README to see how to do it.
4134 Added support for the founder authentication to the Channel
4135 Entry in the server. Affected file silcd/idlist.h.
4137 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4138 server's CMODE command. Affected file silcd/command.c.
4140 * Added the following new functions into lib/silccore/silcauth.[ch]:
4141 silc_auth_get_method and silc_auth_get_data.
4143 * The server now saves the remote hosts public key to the
4144 SilcIDListData pointer. Affected file silcd/protocol.c.
4146 * The normal server now does not remove the channel entry from
4147 the cache if the founder authentication data is set. It used
4148 to remove it if the founder was the last one on the channel on
4149 the server and left the channel. The auth data is saved and
4150 if the channel is re-joined later the old entry is used with
4151 the old auth data. Affected files silcd/command_reply.c and
4154 * Removed the `pkcs' field from the SilcIDListData structure
4155 in the server; it is not used. Affected file silcd/idlist.h.
4157 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4159 * Fixed packet processing on slow links. Partial packets were
4160 never re-processed because the incoming data buffer was cleared
4161 by the application. Application must not directly clear the
4162 sock->inbuf, the packet processing routines handle it. Fixed
4163 this in client library and in server.
4165 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4167 * Fixed the WHOIS and IDENTIFY send reply function to really
4168 check whether to send list or just one entry. Affected file
4171 * Cleaned up the LEAVE command's channel key distribution. The
4172 affected file silcd/command.c.
4174 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4175 can enforce the channel mode as well. In that case the ID
4176 includes the ID of the server. The code now enforces the
4177 mode change if the router have different mode than the server.
4179 * The notify client operation with CMODE_CHANGE notify can now
4180 return NULL client_entry pointer if the CMODE was not changed
4181 by client. Application must check for this.
4183 * Added <Server ID> argument to INFO command to support server
4184 info fetching by Server ID.
4186 * Added silc_server_announce_get_channel_users to get assembled
4187 packets of channel users of the specified channel. Affected
4188 file silcd/server.[ch].
4190 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4191 was freed underneath the ID Cache.
4193 * Re-announce clients when the server received CHANNEL_CHANGE
4194 notify from the router. Affected file silcd/packet_send.c.
4196 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4198 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4199 crashed since it did not handle the fact that there is no cipher
4200 called "3" and didn't check the error condition. Now fixed.
4202 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4203 flag. It can be used to send message requests.
4205 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * Implemented the RESTART command in the client.
4209 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4210 notice type messages. Added notice printing to the user
4213 * The channel keys are not re-generated if the channel's mode
4214 is PRIVKEY, ie private key on the channel exists. Affected
4215 files silcd/server.c and silcd/command.c.
4217 * Fixed a little bug in channel message delivery when channel
4218 private keys are set in the server. Affected file is
4219 silcd/packet_send.c.
4221 * Changed the setting on channel->on_channel = TRUE from the
4222 silc_client_save_channel_key to the JOIN command reply. The
4223 key payload is not received if the private channel key is set.
4224 Affected file lib/silcclient/command_reply.c and the
4225 lib/silcclient/client_channel.c.
4227 * When the CMODE_CHANGE notify is sent and the channel private
4228 key mode is removed the channel key must be re-generated in
4229 other cells as well. Added this support for the router in the
4230 silcd/packet_receive.c.
4232 * Added new local command NOTICE to send notice message on
4233 channel. Affected file silc/local_command.[ch].
4235 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4237 * Added new local command ME to the client. It is used to send
4238 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4239 some action. Affected file silc/local_command.[ch].
4241 * Changed channel_message and private_message client operations
4242 to deliver the message flags to the application. Added also
4243 the `flags' arguments to the silc_client_send_channel_message
4244 and silc_client_send_private_message functions. Affected file
4247 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4249 * Redefined the Private Message Payload to support private message
4250 keys and to support the new private message flags. Updated
4251 the protocol specs. Flags makes it possible to have for example
4252 CTCP style messages.
4254 * Added new type SilcPrivateMessagePayload and defined an API
4255 for it in the lib/silcclient/silcprivate.[ch].
4257 * Tested private message private keys successfully. Tested the
4258 private message key set, unset and list commands with the new
4261 * Redefined the Channel Message Payload to include the channel
4262 message flags (equal with private message flags) to support
4263 for example CTCP style messages.
4265 * Defined some of the message (for channel and private message)
4266 flags. Updated the protocol specs and added the flags to the
4267 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4269 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4271 * Added SilcKeyAgreementStatus type to the key agreement routines
4272 to indicate the current status and error if one occured.
4273 The status types are defined in the lib/silcclient/silcapi.h.
4275 * Added new local command KEY that is used to set and unset private
4276 keys for channels, set and unset private keys for private messages
4277 with remote clients and to send key agreement requests and
4278 negotiate the key agreement protocol with remote client. The
4279 key agreement is supported only to negotiate private message keys,
4280 it currently cannot be used to negotiate private keys for channels,
4281 as it is not convenient for that purpose.
4283 * Fixed a minor pending callback setting bug in the function
4284 silc_client_get_client_by_id_resolve, now the function works.
4285 Affected file lib/silcclient/idlist.c.
4287 * Added function silc_net_get_local_port to get local bound
4288 port by socket. Added to lib/silcutil/silcnet.[ch].
4290 * Added `sockets' and `sockets_count' fields to the SilcClient
4291 object. They hold the sockets of the listenning sockets in
4292 the client. Listenning sockets may be for example the key
4293 agreement server. Affected file lib/silcclient/client.[ch].
4294 Added functions the silc_client_add_socket and the
4295 silc_client_del_socket. They are exported to the application
4298 * Added ~./silc/clientkeys to support other client's public keys.
4300 * Renamed verify_server_key client operation to verify_public_key
4301 and added one argument to indicate the type of the connection
4302 (server, client etc.).
4304 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4306 * Added silc_server_connection_auth_request to handle the
4307 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4308 silcd/packet_receive.[ch].
4310 * Added silc_server_send_connection_auth_request into the
4311 silcd/packet_send.c to send the connection auth request packet.
4313 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4316 * Fixed the public key authentication in responder side in the
4317 server. The `auth_data' pointer includes the SilcPublicKey
4318 not the path to the public key. Affected file silcd/protocol.c.
4320 * Implemented the public key authentication in the initiator side
4321 in the server. Affected file silcd/protocol.c.
4323 * Removed the [RedirectClient] config section from the server
4324 configuration. Is not needed and I don't want to implement it.
4326 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4328 * Cleaned up the CMODE command in the server. It now works
4329 correctly and supports all the modes defined in the protocol.
4330 Affected file is silcd/command.c.
4332 * Added `hmac_name' field to the SilcChannelEntry in the server
4333 to hold the default HMAC of the channel. It can be set when
4334 creating the channel (with JOIN command). Affected files
4337 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4338 type to indicate the change of the current cipher and hmac
4339 on the channel. Client can safely ignore the <cipher> argument
4340 (if it chooses to do so) since the CHANNEL_KEY packet will
4341 force the channel key change anyway. The <hmac> argument is
4342 important since the client is responsible of setting the new
4343 HMAC and the hmac key into use.
4345 * Fixed the CMODE command in the client library as well.
4347 * Tested CMODE command in router environment successfully.
4349 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Show the version of the remote client (or server) when connecting
4352 to the server. It is logged to the log file. Affected file
4353 is silcd/protocol.c.
4355 * Fixed the KILLED notify handling in the client library. The
4356 client must be removed from all channels when receiving the
4359 Also, do not remove the client entry when giving the KILL
4360 command but when the KILLED notify is received.
4362 * Removed silc_idlist_find_client_by_nickname from the server.
4363 Not needed anymore. Affected files silcd/idlist.[ch].
4365 * Implemented the CHANNEL_CHANGE notify type handling to the
4366 server. Affected file silcd/server.c.
4370 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4372 * Added silc_server_send_notify_invite to send the INVITE
4373 notify between routers.
4375 * Implemented the INVITE command correctly to the server.
4377 * Implemented the INVITE notify type handling in the server.
4379 * Implemented the INVITE command to the client library and on the
4382 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4384 * Added function silc_server_get_client_resolve to find the
4385 client entry by ID from all ID lists and then resolve it
4386 (using WHOIS) if it cannot be found. Affected file is
4389 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4391 * Implemented the BAN command to the client library.
4393 * The JOIN command in the server now checks the invite list
4396 * Changed the silc_command_reply_payload_encode_va and the
4397 silc_command_payload_encode_va to support that if argument is
4398 NULL it ignores and checks the next argument. Affected file
4399 lib/silccore/silccommand.c.
4401 * Added silc_server_send_notify_ban to send the BAN notify
4402 type between routers.
4404 * Chaned the silc_notify_payload_encode to support that if
4405 argument is NULL it ignores and checks the next argument.
4406 Affected file lib/silccore/silcnotify.c.
4408 * Tested ban lists in router environment successfully.
4410 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4412 * Implemented BAN command to the server, in silcd/command.[ch].
4414 * Removed the BAN and INVITE_LIST modes from the CMODE command
4417 * Added function silc_string_match to regex match two strings.
4418 Affected files lib/silcutil/silcutil.[ch].
4420 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Redefined parts of the SilcChannelEntry in the server to support
4423 the new ban and invite lists.
4425 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4427 * Redefined the INVITE command. The same command can be used to
4428 invite individuals to the channel but also to manage the invite
4429 list of the channel (to add to and remove from the invite list).
4430 Updated the protocol specs.
4432 * Added new command SILC_COMMAND_BAN that can be used to manage
4433 the ban list of the channel. Updated the protocol specs.
4435 * Removed the channel modes: the SILC_CMODE_BAN and the
4436 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4437 in the CMODE command. The equivalent features are now available
4438 using INVITE and BAN commands. Updated the protocol specs.
4440 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4441 in the network about change in the current ban list. The notify
4442 type is not used by the client.
4444 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4445 support the invite lists.
4447 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4449 * Added new function silc_string_regexify that converts string
4450 including wildcard characters into regex string that can
4451 be used by the GNU regex library. Added into the file
4452 lib/silcutil/silcutil.[ch].
4454 Added silc_string_regex_combine to combine to regex strings
4455 into one so that they can be used as one regex string by
4456 the GNU regex library. Added into the file
4457 lib/silcutil/silcutil.[ch].
4459 Added silc_string_regex_match to match two strings. It returns
4460 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4462 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * Imported GNU regex to the soruce tree into lib/contrib.
4465 Fixed some compiler warning from the regex.c.
4467 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4469 * Fixed MOTD command in the server to work in router environment.
4471 * Fixed the MOTD command in the client library to support
4472 the server argument in the command.
4474 * Added `nickname_len' argument to the silc_idlist_add_client
4475 in the server, as the `nickname' argument may be binary data
4478 * Added silc_idlist_get_channels to return all channels from
4481 * Implemented LIST command to the server. Affected file is
4484 * Implemented the LIST command to the client library and on the
4487 * Added [<user count>] argument to the LIST command reply.
4488 With private channels the user count is not shown.
4490 * Updated TODO and README.
4492 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * The client entry's data.registered must be TRUE even with
4495 global client entry on global client list. The data.registered
4496 is used to check whether the client is anymore in the network,
4497 for example with WHOWAS command so it must be valid.
4499 * Fixed the WHOWAS command in the server. It now actually works
4500 in router environment. Added function into silcd/command_reply.c
4501 silc_server_command_reply_whowas_save.
4503 * Added silc_idlist_purge function to the silcd/idlist.c
4504 to periodically purge the ID Cache.
4506 * Fixed INFO command in the server. It works now in router
4507 environment. Added <server name> argument to the INFO command
4508 reply. Updated the protocol specs.
4510 * Fixed minor bug in silc_idcache_purge to not purge if the
4511 expire value is zero.
4513 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4514 they were buggy because of the WHOWAS information.
4516 * Fixed local command MSG to handle the async resolving of
4517 the remote client properly. It used to fail the first MSG.
4518 Affected file silc/local_command.c.
4520 * Added `data_len' field to SilcIDCache context.
4522 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * Update TODO. Todo in commands in the server.
4526 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4528 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4529 used by routers as broadcast packet to inform other routers
4530 about the changed user mode.
4532 Implemented the notify handling in the server. Affected file is
4533 silcd/packet_receive.c. Added the function
4534 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4536 * Added new generic Channel Payload and deprecated the New Channel
4537 Payload. The New Channel Payload is now the generic Channel
4540 * Added new argument `mode' to the silc_server_send_new_channel
4541 as it is required in the Channel Payload now.
4543 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4544 and created a new and real SilChannelPayload to represent the
4545 new generic Channel Payload. Implemented the encode/decode
4546 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4548 * Added silc_server_get_client_channel_list to return the list
4549 of channels the client has joined for WHOIS command reply.
4550 Affected file silcd/server.[ch].
4552 * Implemented the channel list sending in the WHOIS command reply
4553 in server and in the client.
4555 Implemented the channel list displaying on the user interface
4556 as well. Affected file silc/client_ops.c.
4558 * Added silc_channel_payload_parse_list to parse list of Channel
4559 Payloads. It returns SilcDList list of SilcChannelPayloads.
4560 Client for example can use this function to parse the list of
4561 channels it receives in the WHOIS command reply. The caller
4562 must free the list by calling silc_channel_payload_list_free.
4563 Affected files lib/silccore/silcchannel.[ch].
4565 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4567 * Added one new argument <user mode> to the WHOIS command reply
4568 to return the mode of the user in SILC. Updated the protocol
4571 Implemented it to the server and client.
4573 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Fixed the mode printing on the user interface on joining.
4576 Affected file silc/client_ops.c.
4578 * Implemented the UMODE command and user modes in general to the
4579 client library and to the user interface.
4581 * Implemented the UMODE command to the server.
4583 * The server now sends UNKNOWN_COMMAND error status if client sends
4584 unknown command. Affected file silcd/command.c.
4586 * All server commands now handle the command identifier the right
4587 way when sending the command reply to the client. The client can
4588 use to identify the command replies with the identifier.
4590 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4592 * Added silc_server_get_client_route to resolve the route to
4593 the client indicated by the client ID. Affected file is
4596 * Added silc_server_relay_packet as general function to relay
4597 packet to arbitrary destination. This deprecates functions
4598 like _send_private_message_key, _relay_notify etc. Affected
4599 file is silcd/packet_send.[ch].
4601 Removed silc_server_send_key_agreement,
4602 silc_server_send_private_message_key and
4603 silc_server_packet_relay_notify functions from the file
4604 silcd/packet_send.[ch].
4608 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4609 server. Affected file silcd/packet_receive.[ch].
4611 * Implemented the KILL command to the client. Implemented the
4612 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4613 Affected files lib/silcclient/command[_reply].c and
4614 lib/silcclient/client_notify.c. Implemented the KILL notify
4615 printing in the user inteface.
4617 * Fixed a lot silc_parse_nick memory leaks from the client
4618 library in the file lib/silcclient/command.c.
4620 * Changed the silc_server_send_notify_on_channels's `sender'
4621 argument from SilcSocketConnection to SilcClientEntry to
4622 check the sender as entry and not as connection object and not
4623 to send to the client provided as argument. The affected file
4624 is silcd/packet_send.[ch].
4626 * The notify packets that are destined directly to the client used
4627 to not to be processed by the server. Now changed that and the
4628 server processes all notify packets. After relaying the packet
4629 to the client the notify packet is processed in the server.
4631 * The silc_server_free_client_data now checks whether there is
4632 pending outgoing traffic for the client and purges the data to
4633 the network before removing the client entry.
4635 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4637 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4638 an client is killed from the SILC Network. Updated the protocol
4641 Added new function silc_server_send_notify_killed to the
4642 silcd/packet_send.[ch].
4644 * Added function silc_server_packet_relay_notify to relay notify
4645 packets that are destined directly to a client. In this case
4646 the server does not process the notify packets but merely relays
4647 it to the client. Affected file silcd/packet_send.[ch].
4649 Added also silc_server_packet_process_relay_notify to check
4650 whereto relay the notify. Affected file is
4651 silcd/packet_receive.[ch].
4653 * Implemented the KILL command to the server.
4657 * Added the backup schema desgined last fall to the protocol
4658 specs for everyone to see. The specification is in the
4659 *-spec-xx.txt draft and the packet type definitions for the
4660 backup routers is in *-pp-xx.txt draft. Thusly, added also
4661 new packet type SILC_PACKET_CELL_ROUTERS.
4663 * A big security problem in the implementation discovered. The
4664 signoff of an client did not cause new channel key generation
4665 which it of course should've done. The channel keys must be
4666 always re-generated when client leaves (or signoffs) the channel.
4667 The silc_server_remove_from_channels funtion now handles
4668 the channel key re-generation.
4670 * Added `sender' argument to the silc_server_send_notify_on_channels
4671 to not to send the client provided as argument. Affected file
4672 silcd/packet_send.[ch].
4674 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Implemented OPER and SILCOPER commands into the server and
4679 * Added silc_auth_verify and silc_auth_verify_data to verify
4680 the authentication directly from the authentication payload.
4681 It supports verifying both passphrase and public key based
4682 authentication. Affected file lib/silccore/silcauth.[ch].
4684 * Added `hash' field to the SilcIDListData structure. It is the
4685 hash negotiated in the SKE protocol. Affected file is
4688 * Slight redesigning of the SilcAuthPayload handling routines.
4689 Do not send SilcPKCS but SilcPublicKey as argument.
4691 * Implemented the public key authentication support to the
4692 serverconfig. The public key is loaded from the provided path
4693 and saved as authentication data to void * pointer. Thus,
4694 changed the unsigned char *auth_data to void *auth_data;
4696 * Fixed SHUTDOWN command to send the reply before the server
4697 is shutdown. :) Affected file silcd/command.c.
4699 * Fixed fatal bug in CONNECT command. The hostname was invalid
4700 memory and server crashed. Affected file silcd/command.c.
4702 * Fixed fatal bug in CLOSE command. The server_entry became
4703 invalid but was referenced later in the command. Affected file
4706 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4708 * Fixed fatal bug in failure packet handling. Server ignored
4709 the failure and thus crashed when it came.
4713 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4715 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4716 that the command may be executed only once in (about) 2 seconds.
4717 The old SILC_CF_LAG flag is same but allows command bursts up
4718 to five before limiting.
4720 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4721 server code. Various commands now includes the CF_LAG_STRICT
4722 flag to disallow any kind of miss-use of the command.
4724 * Fixed the silc_buffer_unformat to not to allocate any data
4725 if the length of the data is zero. It used to allocate the
4726 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4728 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Changed the format of AdminConnection configuration section
4731 in the server. Added username of the admin to the format.
4732 Affected files silcd/serverconfig.[ch].
4734 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4735 to return admin configuration data by host, username and/or
4738 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Implemented WHOWAS command to the server. Added the functions:
4742 silc_server_command_whowas_parse,
4743 silc_server_command_whowas_send_reply,
4744 silc_server_command_whowas_from_client and
4745 silc_server_command_whowas_from_server
4747 * Added <Client ID> argument to the WHOWAS command reply. Updated
4748 the protocol specs accordingly.
4750 * Implemented WHOWAS command and command_reply to the client
4753 Implemented the WHOWAS printing on the user interface.
4755 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4757 * Added new argument to the WHOWAS command reply, the real name.
4758 It is an optional argument. Updated the protocol specs.
4760 * Added SilcIDCacheDestructor callback that is registered when
4761 the SilcIDCache is allocated. The callback is called when
4762 an cache entry in the ID Cache expires, or is purged from the
4763 cache. Added into lib/silccore/idcache.[ch].
4765 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4766 to destruct the client entries when the cache entry expires.
4767 Other ID Cache's in server and in the client library ignores
4770 * If the ID Cache entry's `expire' field is zero then the entry
4771 never expires. Added boolean `expire' argument to the
4772 silc_idcache_add function in the lib/silccore/idcache.[ch].
4773 If it is TRUE the default expiry value is used.
4775 * Added silc_server_free_client_data_timeout that is registered
4776 when client disconnects. By default for 5 minutes we preserve
4777 the client entry for history - for WHOWAS command.
4779 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4781 * Added support to the server to enforce that commands are not
4782 executed more than once in 2 seconds. If server receives
4783 commands from client more frequently, timeout is registered
4784 to process the commands. Affected file silcd/command.c.
4785 Added new function silc_server_command_process_timeout.
4787 * Changed NICK_NOTIFY handling in client library to check that
4788 if the client's nickname was changed, so there is no need to
4789 resolve anything from the server.
4791 * Removed error printing from the WHOIS and IDENTIFY commands.
4792 If error occurs then it is ignored silently in the client library.
4793 The application, however, may map the received error to
4794 human readable error string. The application currently maps
4795 the NO_SUCH_NICKNAME error to string.
4797 * Made the command status message public to the application. Moved
4798 them from lib/silcclient/command_reply.c to
4799 lib/silcclient/command_reply.h. The application can map the
4800 received command status to the string with the
4801 silc_client_command_status_message function.
4803 * Added check to the server to check that client's ID is same
4804 as the Source ID in the packet the client sent. They must
4807 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4809 * Added dist-bzip hook to the Makefile.am to make bzip2
4810 compressed distributions.
4812 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4814 * Server now enforces the maximum length for the nickname and
4815 the channel as protocol specification dictates. 128 bytes for
4816 nickname and 256 bytes for channel name.
4818 * Moved the WHOIS printing to the application. The client libary
4819 does not print out the WHOIS information anymore, the application
4820 must do it. Renamed silc_client_command_reply_whois_print to
4821 the silc_client_command_reply_whois_save.
4823 The client's idle time is also sent to the application now, and
4824 the idle is shown on screen.
4826 * Added silc_client_command_reply_identify_save to save the
4827 received IDENTIFY entries.
4829 * Do not check for channel private keys in message sending and
4830 reception if the channel does not have the PRIVKEY mode set.
4831 Affected file lib/silclient/client_channel.c.
4833 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4835 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4836 just surfaced after chaning the JOIN procedure.
4838 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4840 * Added silc_client_get_clients_by_list to get client entries
4841 from Client ID list, that is returned for example by JOIN
4842 and USERS command replies. The application should use this
4843 function for example when JOIN command reply is received to
4844 resolve the clients already on the channel (library does not
4845 do that anymore as USERS command reply is not used in the JOIN
4846 procedure anymore). Affected files lib/silcclient/silcapi.h and
4847 lib/silcclient/idlist.c.
4849 * JOIN command reply and USERS command reply returns now SilcBuffer
4850 pointers instead of unsigned char pointers when returning
4851 the client list and mode list.
4853 * Added <Client ID> argument to the JOIN command reply, mainly
4854 for the server to identify for which client the command was
4855 originally sent. Updated protocol specs accordingly.
4857 * Added SilcDlist private_key pointer to the SilcChannelEntry
4858 in the client to support the channel private keys. Affected
4859 file is lib/silcclient/idlist.h.
4861 * Added SilcChannelPrivateKey argument to the function
4862 silc_client_send_channel_message so that application can choose
4863 to use specific private ke if it wants to. If it is not provided,
4864 the normal channel key is used, unless private keys are set.
4865 In this case the first (key that was added first) is used
4866 as the encryption key.
4868 * Implemented the support for channel private key handling.
4869 Implemented the following functions:
4871 silc_client_add_channel_private_key,
4872 silc_client_del_channel_private_keys,
4873 silc_client_del_channel_private_key,
4874 silc_client_list_channel_private_keys and
4875 silc_client_free_channel_private_keys
4877 Affected file lib/silcclient/client_channel.c.
4879 * Added the support for the private keys in the channel message
4880 sending and encryption and in the message reception and
4881 decryption. Affected funtions are
4882 silc_client_send_channel_message and silc_client_channel_message.
4884 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4886 * Added SKE's key verify callback to the client library's
4887 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4889 * Removed the statement that server (or router) must send USERS
4890 command reply when joining to the channel so that the client
4891 knows who are on the channel. Instead, the client list and
4892 client's mode list is now sent in the JOIN command reply to the
4893 client who joined channel. This is better solution.
4895 * Added function silc_server_get_users_on_channel and function
4896 silc_server_save_users_on_channel to the silcd/server.[ch].
4898 * Removed function silc_server_command_send_users from the
4901 * Do not show topic on the client library anymore. The topic is
4902 sent in the command reply notify to the application and the
4903 application must show the topic now.
4905 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * Added client searching by nickname hash into the IDENTIFY and
4908 WHOIS commands in the server as they were clearly missing from
4909 them. Affected file is silcd/command.c.
4911 * Fixed a bug in private message receiving in the client library.
4912 The remote ID was freed and it wasn't supposed, now it is
4915 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4917 * Minor fix to the channel payload; allocate the data area, as it
4918 needs to be of specific length.
4920 * If the key agreement port is zero then the operating
4921 system will define the bound port. Affected files are
4922 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4924 * Added new function silc_channel_payload_decrypt into the file
4925 lib/silccore/silcchannel.[ch].
4927 * Moved the channel message etc, check from silc_packet_decrypt
4928 to applications. The library calls now a generic
4929 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4930 when the packet is either normal or special. This was done to
4931 allow more wide range of checking that was not allowed when
4932 the code was in library. Now applications can do virtually any
4933 checks to the packet and return to the library the decision how
4934 the packet should be processed. Affected files are
4935 lib/silccore/silcpacket.[ch].
4937 Added silc_server_packet_decrypt_check to the server and
4938 silc_client_packet_decrypt_check to the client library.
4940 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4941 to send with specified source and destination information.
4943 * Channel message delivery between routers was broken after the
4944 channel key distribution was fixed earlier. The channel key
4945 was used be to distributed to other routers as well which is not
4946 allowed by the protocol. Now this is fixed and channel keys
4947 really are cell specific and the channel message delivery between
4948 routers comply with the protocol specification.
4950 * Fixed various commands in server to check also the global list
4951 for the channel entry and not just the local list. The affected
4952 file silcd/command.c.
4954 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4956 * Added assert()s to buffer formatting and unformatting routines
4957 to assert (if --enable-debug) when error occurs. Affected
4958 file: lib/silcutil/silcbuffmt.c.
4960 * Changed to auto-reconnect to check whether the remote host is
4961 router and register the re-connect timeout if it is. It used
4962 to check that whether we are normal server, but router must do
4963 auto-reconnect with another router as well. Affected file
4966 * Removed the [<key len>] option from CMODE command as the cipher
4967 name decides the key length, nowadays. See the defined ciphers
4968 from the protocol specification.
4970 * Added [<hmac>] option to the CMODE command to define the HMAC
4971 for the channel. Added SILC_CMODE_HMAC channel mode.
4973 * Added [<hmac>] option for the JOIN command so that user can
4974 select which HMAC is used to compute the MACs of the channel
4977 * Added Hmac field to the Channel Message Payload. The integrity
4978 of plaintext channel messages are now protected by computing
4979 MAC of the message and attaching the MAC to the payload. The
4980 MAC is encrypted. Now, it is clear that this causes some
4981 overhead to the size of the packet but rationale for this is that
4982 now the receiver can verify whether the channel message decrypted
4983 correctly and also when private keys are set for the channel the
4984 receiver can decrypt the packet with several keys and check from
4985 the MAC which key decrypted the message correctly.
4987 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4988 lib/silccrypt/silccipher.[ch].
4990 * Added silc_hash_len to return the digest length into the
4991 lib/silcrypt/silchash.[ch].
4993 * Rewrote parts of Silc Channel Payload interface in the
4994 lib/silccore/silcchannel.[ch]. The encode function now also
4995 encrypts the packet and parse function decrypts it.
4997 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4999 * Fixed a minor formatting bug in the SKE's key material processing.
5000 It actually might have processed the keys wrong way resulting
5003 * Redefined the mandatory HMAC algorithms and added new algorithms.
5004 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5005 and hmac-md5 truncated to 96 bits. The mandatory is now
5006 hmac-sha1-96. Rest are optional (including the one that used
5007 to be mandatory). Rationale for this is that the truncated HMAC
5008 length is sufficient from security point of view and can actually
5009 make the attack against the HMAC harder. Also, the truncated
5010 HMAC causes less overhead to the packets. See the RFC2104 for
5013 * Added new [hmac] configuration section. The SKE used to use
5014 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5015 is of course wrong. The official names that must be proposed in
5016 the SKE are the ones defined in the protocol specification
5017 (hmac-sha1-96 for example). The user can configure any hmac
5018 using any hash function configured in the [hash] section. At
5019 least, the mandatory must be configured.
5021 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5023 * Added HMAC list to the SKE proposal list. It has now both
5024 hash algorithm list and HMAC list. This makes the protocol
5025 incompatible with previous versions. The SKE now seems to work
5026 the way it is supposed to work, for the first time actually.
5028 * Defined plain Hash algorithms to the protocol specification.
5031 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5033 * Implemented support for key agreement packets into the server.
5034 Added functions silc_server_key_agreement and
5035 silc_server_send_key_agreement. Other than these functions,
5036 server has nothing to do with this packet.
5038 * Added support for private message key packets into the server.
5039 Added functions silc_server_private_message_key and
5040 silc_server_send_private_message_key.
5044 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5045 called in the protocol's final callback instead in the END
5046 protocol state. This makes a little more sense and in the same
5047 time in client we can use the same protocol routines for normal
5048 key exchange and to key agreement packet handling as well.
5050 * Added to both client's and server's KE protocol context the
5051 SilcSKEKeyMaterial pointer to save the key material. We will
5052 bring the key material to the protocol's final callback by doing
5053 this. The final callback must free the key material.
5055 * Added SKE's packet_send callback into client's KE protocol
5056 context so that the caller can choose what packet sending function
5057 is used. This way we can use different packet sending when
5058 doing normal SKE when doing key agreement packet handling (in
5059 the key agreement packet handling we do not want to encrypt
5062 * Implemented the responder side of the key agreement routines
5063 in the client. The client can now bind to specified port and
5064 accept incoming key negotiation. The key material is passed
5065 to the application after the protocol is over.
5067 * Implemented the processing of incoming Key Agreement packet
5068 in the client. Added function silc_client_key_agreement to
5071 * Implemented the intiator side of the key agreement routines
5072 in the client. The client can now initiate key agreement with
5073 another remote client. The key material is passed to the
5074 application after the protocol is over.
5076 * Created client_keyagr.c to include all the key agreement
5079 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5080 SILC_TASK_CALLBACK except that it is not static.
5082 * Created client_notify.c and moved the Notify packet handling
5083 from the client.[ch] into that file.
5085 * Created client_prvmsg.c and moved all private message and
5086 private message key routines from the client.[ch] into that file.
5088 * Create client_channel.c and moved all channel message and
5089 channel private key routines from the client.[ch] into that file.
5091 * Changed silc_client_get_client_by_id_resolve to resolve with
5092 WHOIS command instead of IDENTIFY command, in the file
5093 lib/silclient/idlist.c.
5095 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5097 * Implemented the SKE's responder side to the Client library.
5099 * When FAILURE is received to the protocol do not trust it
5100 blindly. Register a timeout to wait whether the remote closes
5101 the connection as it should do it, only after that process the
5102 actual failure. This was changed to both client and server.
5104 * Added client_internal.h to include some of the structures
5105 there instead of client.h in lib/silcclient/.
5107 * Added function silc_task_unregister_by_callback to unregister
5108 timeouts by the callback function.
5110 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * Some "Incomplete WHOIS info" errors has been appearing on the
5113 log files. Took away the entry->userinfo check from WHOIS
5114 reply sending. The entry->userinfo is now " " if client did not
5115 provide one. I thought this was fixed earlier but something
5116 is wrong still. Let's see if the error still appears.
5118 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5120 * Fixed a minor bug in the login when the channel key is
5121 re-generated in the server. It used to generate the key in
5122 wrong order and thus caused problems in the channel traffic.
5124 * Fixed a minor bug in channel key distsribution after
5125 KICK command. The key was not sent to the router even though
5128 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5130 * Added silc_ske_process_key_material_data as generic routine
5131 to process any key material as the SILC protocol dictates. The
5132 function is used by the actual SKE library but can be used by
5133 applications as well. This relates to the private message keys
5134 and the channel private keys since they must be processed the
5135 same way the normal SILC session keys. The protocol dictates
5136 this. Affected files: lib/silcske/silcske.[ch].
5138 Added also silc_ske_free_key_material to free the
5139 SilcSKEKeyMaterial structure.
5141 * Defined silc_cipher_set_key function to set the key for
5142 cipher without using the object's method function. The affected
5143 files: lib/silccrypt/silccipher.[ch].
5145 * Implemented silc silc_client_add_private_message_key,
5146 silc_client_add_private_message_key_ske,
5147 silc_client_del_private_message_key,
5148 silc_client_list_private_message_keys and
5149 silc_client_free_private_message_keys functions in the
5152 Added functions silc_client_send_private_message_key to send
5153 the Private Message Key payload and silc_client_private_message_key
5154 to handle incoming Private Message Key payload.
5156 * Added Cipher field to the Private Message Key payload to set
5157 the cipher to be used. If ignored, the default cipher defined
5158 in the SILC protocol (aes-256-cbc) is used.
5160 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5162 * Removed lib/silcclient/ops.h file.
5164 Redefined parts of the SILC Client Library API. Created new
5165 file silcapi.h that deprecates the ops.h file and defines the
5166 published Client Library API. Defined also private message key
5167 API and channel private key API into the file.
5169 This is the file that the application must include from the
5170 SILC Client Library. Other files need not be included by
5171 the application anymore.
5173 * Added new key_agreement client operation callback and also
5174 defined the Key Agreement library API for the application.
5176 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5178 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5179 is used by clients to request key negotiation between another
5180 client in the SILC network. If the negotiation is started it
5181 is performed using the SKE protocol. The result of the
5182 negotiation, the secret key material, can be used for example
5183 as private message key.
5185 Implemented the Key Agreement payload into the files
5186 lib/silccore/silauth.[ch].
5188 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5190 * Redefined ciphers for the SILC protocol. Added some new ciphers
5191 and defined the key lengths for the algorithms. Changed the
5192 code accordingly. The default key length is now 256 bits.
5194 * Fixed SKE key distribution function silc_ske_process_key_material
5195 when the key length is more than 128 bits. The default key
5196 length in SILC is now 256 bits.
5198 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5199 to indicate unsupported algorithm.
5201 * Renamed rijndael.c to aes.c and all functions as well.
5203 * Fixed a long standing channel key setting bug in client library.
5204 Weird that it has never surfaced before.
5206 * Fixed bug in channel deletion. If the entire channel is removed
5207 then it must also delete the references of the channel entry
5208 from the client's channel list as the client's channel entry and
5209 the channel's client entry share same memory.
5211 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * Implemented CONNECT and SHUTDOWN commands in the client.
5215 * Implemented CLOSE command to the client.
5217 * Added the function silc_idlist_find_server_by_name into the
5218 files silcd/idlist.[ch].
5220 Added the function silc_idlist_find_server_by_conn into the
5221 files silcd/idlist.[ch].
5223 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5225 * DIE command was renamed to SHUTDOWN. Updated the both code
5228 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5229 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5231 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5234 * Added function silc_server_create_connection function to create
5235 connection to remote router. My server implementation actually
5236 does not allow router to connect to normal server (it expects
5237 that normal server always initiates the connection to the router)
5238 so the CONNECT command is only good for connecting to another
5241 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5244 or some other client was kicked from the channel.
5246 Implemented the handling of the notify type to both client
5249 Implemented silc_server_send_notify_kicked to send the KICKED
5250 notify. It is used to send it to the server's primary router.
5252 * Implemented the KICK command into server and client.
5254 * Added `query' argument to the silc_idlist_get_client function
5255 to indicate whether to query the client from server or not if
5258 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5259 to indicate that the client is not channel founder.
5263 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5265 * Removed the rng context from SilcPacketContext structure and
5266 changed that the packet routine uses the Global RNG API.
5268 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5270 * Added support for quit message that client can "leave" on the
5271 channel when it quits the SILC. It is ditributed inside the
5272 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5274 Added silc_server_free_client_data that will take the
5275 signoff message as argument.
5277 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5279 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5281 * Updated parts of the protocol specification to keep it up
5284 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5286 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5287 payloads in one packet.
5289 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5290 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5291 use now the new List flag.
5293 * Also deprecated the following packet types: REPLACE_ID,
5294 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5296 * Added list support for Notify packet in server.
5298 * Added silc_server_send_notify_channel_change to send the
5299 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5300 the silc_server_send_replace_id.
5302 * Added silc_server_send_notify_nick_change to send the
5303 NICK_CHANGE notify type. Deprecates the function
5304 silc_server_send_replace_id.
5306 * Added silc_server_send_notify_join to send the JOIN notify type.
5307 Deprecates the function silc_server_send_new_channel_user.
5309 * Added silc_server_send_notify_leave to send LEAVE notify type.
5310 Deprecates the function silc_server_send_remove_channel_user.
5312 * Added silc_server_send_notify_cmode and
5313 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5314 types. Deprecates the silc_server_send_set_mode function.
5316 * Added SERVER_SIGNOFF notify type to indicate that server has
5317 quit. This means that all clients on the channel from that
5318 server will drop. This can be also used when netsplit happens.
5320 Deprecated REMOVE_ID packet type since it is not needed anymore
5323 Added silc_server_send_notify_server_signoff to send the
5324 SERVER_SIGNOFF notify type. Deprecates the function
5325 silc_server_send_remove_id.
5327 Added also silc_server_send_notify_signoff to send the
5328 SIGNOFF notify type.
5330 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5331 SILC protocol from this day on. Changed the protocol
5332 specification as well.
5334 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5335 notify type. It is used between routers to notify about
5336 topic changes on a channel.
5338 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5341 * Partly updated the protocol specification to comply with the
5342 changes now made. It is still though a bit outdated.
5344 * The JOIN notify type now takes one extra argument <Channel ID>.
5345 The packet used to be destined to the channel but now the
5346 JOIN type may be sent as list thus it is impossible to
5347 destine it to any specific channel. By adding this argument
5348 it is again possible.
5350 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5352 * Added CREDITS file. The CHANGES and CREDITS file will appear
5353 in the distribution as well.
5355 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5357 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5358 types in the server's silcd/packet_receive.c.
5360 * Implemented CMODE and CUMODE to work in router environment.
5362 * Fixed minor encoding and decoding buglet from the
5363 lib/silccore/silcmode.c.
5365 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5368 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5370 * Changed all SilcConfigServer* and silc_config_server* to
5371 SilcServerConfig* and silc_server_config*, respectively.
5374 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5376 * Associated the ID (client or server ID) to the Authentication
5377 Payload to avoid any possibility of forging. Updated the
5378 protocol specification and the code accordingly.
5380 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5382 * The RSA key length is now save to the RsaKey context in the
5383 key generation process in lib/silccrypt/rsa.c. The key length
5384 is now used to figure out the maximum size of the block allowed
5385 to be encrypted/signed.
5387 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5388 is equivalent to the silc_mp_mp2bin but does not allocate any
5391 * Changed silc_mp_mp2bin API to take length argument. If it is
5392 non-zero then the buffer is allocated that large. If zero, then
5393 the size is approximated using silc_mp_sizeinbase, which however
5396 * Created Global RNG API which is global RNG that application can
5397 initialize. After initializing, any routine anywhere in the
5398 code (including library) can use RNG without allocating a new
5399 RNG object. This was done to allow this sort of use of the
5400 RNG in code that has no chance to allocate RNG object. All
5401 applications currently allocate this and many routines in the
5402 library use this. Affected file lib/silccrypt/silcrng.[ch].
5404 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5405 it to use the Global RNG API.
5407 * Defined Authentication Payload into protocol specification that
5408 is used during SILC session to authenticate entities. It is
5409 used for example by client to authenticate itself to the server
5410 to obtain server operator privileges.
5412 Implemented this payload into the lib/silccore/silcauth.[ch].
5413 Implemented also routines for public key based authentication
5414 as the new protocol specification dictates.
5416 Moved definitions of different authentication methods from
5417 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5419 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5420 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5421 silc_pkcs_verify_with_hash functions into the file
5422 lib/silccrypt/silcpkcs.[ch].
5424 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5426 * The client entry's userinfo pointer must be always valid.
5427 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5428 will fail since it requires the userinfo. Now, the userinfo
5429 is allocated as "" if actual userinfo does not exist. Actually,
5430 it must exist and it is totally Ok to drop client connections
5431 that does not announce the userinfo. However, we will make
5432 this workaround for now.
5434 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5435 to return the remote port by socket.
5437 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5439 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5440 SILC_SERVER_PENDING_EXEC and added an new macro
5441 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5442 data or when error occurs while processing the pending command.
5444 Added new argument `destructor' into silc_server_command_pending
5445 and to the SilcServerCommandPending object. This destructor is
5446 now called after calling the pending callback or if error occurs
5447 immediately. If error occurs the actual pending callback won't
5448 be called at all - only the destructor. The destructor may be
5449 NULL if destructor is not needed.
5451 All this applies for client library code as well. Similar
5452 changes were made there as well for the pending commands.
5454 In the client, the application must now allocate the
5455 SilcClientCommandContext with the silc_client_command_alloc
5458 * Added reference counter to the SilcServerCommandContext. Added
5459 function silc_server_command_alloc and silc_server_command_dup
5462 Same type of functions added to the client library for the same
5465 * Removed the cmd_ident from IDListData away since it is now
5466 global for all connections. It is the command identifier used
5467 in command sending and with pending commands. The affected file
5470 * Added reference counter to the SilcSocketConnection objecet to
5471 indicate the usage count of the object. The object won't be
5472 freed untill the reference counter hits zero. Currently only
5473 server uses this, and client ignores it. The client must be
5474 set to use this too later. The affected files are
5475 lib/silccore/silcsockconn.[ch]. Added also the function
5476 silc_socket_dup to increase the reference counter.
5478 This was mainly added because it is possible that the socket
5479 is removed underneath of pending command or other async
5480 operation. Now it won't be free'd and proper DISCONNECTING
5481 flags, etc. can be set to avoid sending data to connection that
5482 is not valid anymore.
5484 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5485 the connection. After that it sets SILC_SET_DISCONNECTED.
5486 It is, however, possible that the socket data is not still freed.
5487 The silc_server_packet_process now checks that data is not
5488 read or written to connection that is DISCONNECTED. The socket
5489 get's freed when the reference counter hits zero.
5491 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5493 * Changed the client operation API: channel_message operation's
5494 `sender' is now the client entry of the sender, not the nickname
5495 and the `channel' is the channel entry, not the channel name.
5497 In the private_message operation the `sender' is now also the
5498 client entry of the sender not the nickname.
5500 Affected file is lib/silcclient/ops.h and all applications
5501 using the client operations.
5503 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5505 * Moved the calling of ops->connect() from connect_to_server_final
5506 into receive_new_id functin since that is the point when the
5507 client is actually allowed to send traffic to network. The
5508 affected file is lib/silcclient/client.c.
5510 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5512 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5513 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5514 (if needs broadcasting) instead of broadcasting the packets one
5515 by one which would make a burst in the network traffic.
5517 * Added `broadcast' argument to the functions in silcd/server.[ch]
5518 silc_server_create_new_channel[_with_id] to indicate whether
5519 to send New Channel packet to primary router.
5521 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5523 * Added new function into the silcd/server.[ch] files:
5524 silc_server_create_new_channel_with_id to create new channel with
5525 already existing Channel ID.
5527 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5528 lib/silccore/silcpacket.h. This packet is used t send list of
5529 Set Mode payloads inside one packet. Server uses this to set
5530 the modes for the channels and clients on those channels, that it
5531 announced to the router when it connected to it. The protocol
5532 specification has been updated accordingly.
5534 * The silc_server_new_channel did not handle the packet coming
5535 from normal server as it normally does not send that. However,
5536 when it announces its channels it does send it. Implemented
5537 the support for that.
5539 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5540 into the file lib/silccore/id.h.
5542 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5544 * Fixed memory leaks in the functions silc_idlist_del_client,
5545 silc_idlist_del_channel and silc_idlist_del_server in the file
5546 silcd/idlist.c. All of those leaked like a sieve.
5548 * Fixed some small memory leaks in the client's function
5549 silc_client_notify_by_server.
5551 * Added functions into silcd/server.c: silc_server_announce_clients,
5552 silc_server_announce_channels and silc_server_announce_server.
5553 These functions are used by normal and router server to announce
5554 to its primary router about clients, channels and servers (when
5555 router) that we own. This is done after we've connected to the
5558 These functions effectively implements the following packet types:
5559 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5560 and SILC_PACKET_NEW_ID_LIST.
5562 * Added new functions into the silcd/packet_receive.[ch]:
5563 silc_server_new_id_list, silc_server_new_channel_list and
5564 silc_server_new_channel_user_list to handle the incoming
5565 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5567 * Added support of changing Channel ID in the function
5568 silc_server_replace_id. If the server that announces a channel
5569 to the router already exists in the router (with same name but
5570 with different Channel ID), router is responsible to send
5571 Replace ID packet to the server and force the server to change
5572 the Channel ID to the one router has.
5574 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5575 client that the Channel ID has been changed by the router. The
5576 normal server sends this to the client. Client must start using
5577 the new Channel ID as the channel's ID.
5579 Implemented handling of this new type into lib/silcclient/client.c
5580 into the function silc_client_notify_by_server.
5582 * Added new function silc_idlist_replace_channel_id into the files
5583 silcd/idlist.[ch] to replace the Channel ID.
5585 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5587 * Call silc_server_command_identify_check always when processing
5588 the IDENTIFY command in silcd/command.c
5590 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5592 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5593 send keepalive packets. The packet can be sent by clients,
5594 servers and routers.
5596 Added function silc_socket_set_heartbeat into the file
5597 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5598 If not set, the heartbeat is not performed. The actual
5599 heartbeat is implemented in the low level socket connection
5600 library. However, application is responsible of actually
5603 Added silc_server_send_heartbeat to send the actual heartbeat
5604 packet into silcd/packet_send.[ch]. Server now performs
5605 keepalive with all connections.
5607 * Added silc_task_get_first function into lib/silcutil/silctask.c
5608 to return the timeout task with shortest timeout. There was a bug
5609 in task unregistration that caused problems. TODO has been
5610 updated to include that task system must be rewritten.
5612 * The client library will now resolve the client information when
5613 receiving JOIN notify from server for client that we know but
5614 have incomplete information.
5616 * Rewrote parts of silc_server_remove_from_channels and
5617 silc_server_remove_from_one_channel as they did not remove the
5618 channel in some circumstances even though they should've.
5620 * Encryption problem encountered in server:
5622 The LEAVE command used to send the Channel Key packet to the
5623 router immediately after generating it. However, the code
5624 had earlier sent Remove Channel user packet but not immediately,
5625 ie. it was put to queue. The order of packets in the router
5626 was that Channel Key packet was first and Remove Channel User
5627 packet was second, even though they were encrypted in the
5628 reverse order. For this reason, MAC check failed. Now, this
5629 is fixed by not sending the Channel Key packet immediately but
5630 putting it to queue. However, this is more fundamental problem:
5631 packets that are in queue should actually not be encrypted
5632 because packets that are sent immediately gets encrypted
5633 actually with wrong IV (and thus MAC check fails). So, packets
5634 that are in queue should be encrypted when they are sent to
5635 the wire and not when they put to the queue.
5637 However, the problem is that the current system has not been
5638 designed to work that way. Instead, the packet is encrypted
5639 as soon as possible and left to the queue. The queue is then
5640 just purged into wire. There won't be any fixes for this
5641 any time soon. So, the current semantic for packet sending
5644 o If you send packet to remote host and do not force the send
5645 (the packet will be in queue) then all subsequent packets to the
5646 same remote host must also be put to the queue. Only after the
5647 queue has been purged is it safe again to force the packet
5650 o If you send all packets immediately then it safe to send
5651 any of subsequent packets through the queue, however, after
5652 the first packet is put to queue then any subsequent packets
5653 must also be put to the queue.
5655 Follow these rules and everything works fine.
5657 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5659 * Added new function silc_server_remove_clients_by_server to
5660 remove all client entries from ID list when the server connection
5661 is lost. In this case it is also important to invalidate all
5662 client entires as they hold the invalid server entry. This
5663 fixes fatal bug when server has lost connection and will reconnect
5666 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5668 * Made some sanity checks to silc_server_daemonise like to check
5669 whether the requested user and group actually exists.
5671 * Added sanity check to SKE's silc_ske_responder_finish to check
5672 that the public and private key actually is valid.
5674 * Invalidate the client's nickname when receiving Replace ID
5675 packet and the Client ID is being replaced. This means that the
5676 server will query the nickname if someone needs it (client)
5679 * Sort the ID Cache in client library when the ID Cache data
5680 has changed (needs sorting).
5682 * Do not allow for SILC client to create several connections to
5683 several servers. The client does not support windows right now
5684 and generating multiple connections causes weird behaviour.
5686 Irssi-silc client does support windows and can handle several
5687 connections without problems, see: www.irssi.org and SILC plugin.
5689 * Fixed some places where client was added to the IDList. The
5690 rule of thumb is following (in order to get everything right):
5691 If the client is directly connected local client then the
5692 `connection' argument must be set and `router' argument must be
5693 NULL to silc_idlist_add_client function. If the client is not
5694 directly connected client then the `router' argument must
5695 bet set and the `connection' argument must be NULL to the
5696 silc_idlist_add_client function.
5698 * The funtion silc_server_packet_send_local_channel actually did
5699 not check whether the client was locally connected or not. It
5700 does that now. Fixed a bug related to LEAVE command.
5702 * Fixed Remove Channel User payload parsing bug in server's
5703 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5705 * The server's silc_server_save_channel_key now checks also the
5706 global ID list for the channel as it might not be in the local
5707 list. Fixed a bug related to LEAVE command.
5709 * Is this the end of the [<unknown>] buglet that has been lurking
5710 around for a long time? A little for loop fix in server's
5711 silc_server_command_whois_parse that is used by both IDENTIFY
5712 and WHOIS command. At least, this was a clear bug and a cause
5713 of one type of [<unknown>] buglet.
5715 * WHOIS and IDENTIFY commands call the function
5716 silc_server_command_[whois/identify]_check function even if
5717 we are not router server.
5719 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5721 * Added --with-gmp configuration option. If set the GMP
5722 is always compiled in the SILC source tree. If not set then
5723 it is checked whether the system has the GMP3 installed. If
5724 it has then the GMP won't be compiled (the system's headers
5725 and library is used), if it doesn't have it then the GMP is
5726 compiled in the SILC source tree.
5728 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5730 * Changed RSA private exponent generation to what PKCS #1
5731 suggests. We try to find the smallest possible d by doing
5732 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5733 not security fix but optimization.
5735 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5737 * Added new config entry [Identity] to fork the server and run
5738 it as specific user and group. A patch from Bostik.
5740 * Imported Dotconf configuration library into lib/dotconf.
5741 This will be used to create the SILC configuration files later.
5742 It will appear in the distsribution after this commit.
5744 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5746 * A big code auditing weekend happening. Auditing code for
5747 obvious mistakes, bugs and errors. Also, removing any code
5750 Removed files for being obsolete:
5752 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5753 inline in the file lib/silcutil/silcbuffer.h)
5755 o lib/silcutil/silcbufutil.c (the header has inline versions)
5757 Changed code to fix possible error conditions:
5759 o The buffer formatting routines now check that the destination
5760 buffer really has enough space to add the data. This applies for
5761 both buffer formatting and unformatting
5762 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5763 unformatting was changed to accomodate following rules:
5764 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5765 sent to the function while XXX_*STRING will not allocate or copy
5766 the data into the buffer. Instead it sets the pointer from the
5767 buffer into the pointer sent as argument (XXX_*STRING used to
5768 require that the pointer must be allocated already). This change
5769 makes this whole thing a bit more consistent and more optimized
5770 (note that the data returned in the unformatting with XXX_*STRING
5771 must not be freed now). The routines return now -1 on error.
5773 o Tried to find all code that use buffer_format and buffer_unformat
5774 and added return value checking to prevent formatting and
5775 especially unformatting errors and possible subsequent fatal
5778 o Changed ske->x and ske->KEY to mallocated pointers in
5779 lib/silcske/silcske.h. Fixed possible data and memory leak.
5781 o Added return value checking to all *_parse* functions. Fixed
5782 many memory leaks as well.
5784 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5785 so that buffer overflows would not happen. All code now also
5786 checks the return value as it can fail.
5788 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5790 * Added reconnection support to server if the normal server looses
5791 its connection to the router (for example if router is rebooted).
5792 The server performs normal reconnection strategy implemented
5793 to the server. Affected file silcd/server.c.
5795 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Added new packet type SILC_PACKET_SET_MODE that is used to
5798 distribute the information about changed modes (for clients,
5799 channels and clients channel modes) to all routers in the
5800 network. Updated the protocol specification accordingly.
5802 Added functions into silcd/packet_send.c and
5803 silcd/packet_receive.c: silc_server_send_set_mode,
5804 silc_server_set_mode.
5806 Added new files silcmode.[ch] into lib/silccore that implements
5807 the encoding and decoding of Set Mode Payload. Added new type
5808 SilcSetModePayload. Moved the definitions of different modes
5809 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5811 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5813 * Oops, a little mistake in server's connection authentication
5814 protocol. The protocol is not ended with FAILURE but with
5815 SUCCESS if the authentication is Ok. :) Affected file is
5818 * Implemented NICK_CHANGE notify handling in server in the file
5819 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5820 the local clients on the channel. After the changing nickname
5821 in router environment snhould work and the [<unknown>] nickname
5822 should appear no more.
5824 The silc_server_replace_id function that receives the Replace ID
5825 payload now sends the NICK_CHANGE notify type also in the file
5826 silcd/packet_receive.c
5828 * Changed WHOIS and IDENTIFY command to support the maximum amount
5829 of arguments defined in protocol specs (3328 arguments). This
5830 fixed a bug that caused problems when there were more than three
5833 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5835 * Added extra parameter, command identifier, to the
5836 silc_client_send_command so that explicit command identifier
5839 Changed that ID list routines uses specific command identifier
5840 when sending WHOIS/IDENTIFY requests to the server so that they
5841 can be identified when the reply comes back.
5843 Affected files lib/silcclient/command.[ch],
5844 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5846 * Added `sender' argument to silc_server_packet_send_to_channel
5847 to indicaet the sender who originally sent the packet to us
5848 that we are now re-sending. Ignored if NULL. Affected file
5849 silcd/packet_send.[ch].
5851 * Added some server statistics support in silcd/server_internal.h
5852 SilcServerStatistics structure and around the server code. Also
5853 send some nice statistics information when client is connecting
5856 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * Fixed channel ID decoding in server's JOIN command reply in
5859 silcd/command_reply.c
5861 * Fixed braodcasting of replace ID payload to not to send it if
5862 we are standalone server in silcd/packet_receive.c.
5864 * Fixed all channel message sending routines to not to send
5865 packets to clients that has router set, since they are routed
5866 separately in the same function earlier. Affects file
5867 silcd/packet_send.c and all channel packet sending functions.
5869 * In USERS reply, res_argv[i] are not allocated, the table
5870 is allocated. Thus changed that free the table, not its
5873 * In server's whois_check and identify_check if the client is
5874 locally connected do not send any WHOIS commands - they are not
5877 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5879 * Fixed some minor bugs in client when sending WHOIS command. The
5880 arguments was in wrong order.
5882 * Removed statis function add_to_channel from server in
5883 silcd/command.c that was previously used with the joining but
5886 * Tested USERS command in router environment successfully with two
5887 routers, two servers and two clients.
5889 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5891 * Reorganized the USERS command and command reply in client library
5892 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5893 When the command is given by user we register a pending command
5894 callback that will reprocess the command after the reply has been
5895 received from the server. When reprocessing the packet we then
5896 display the information. Thus, the USERS information is displayed
5897 now in the command callback instead of in the command reply
5898 callback. The processing of the command is same as previously
5899 when server has sent the command reply in the JOINing process.
5901 * Added to USERS command in silcd/command_reply.c to join the client,
5902 we didn't use to know about, to the channel after we've created
5903 a client entry for it. Also, for clienet we did know already still
5904 check whether it is on the channel or not and add it if not.
5906 * Removed silc_server_command_join_notify as the function and its
5909 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5911 * Changed the client's pending command handling to the same as the
5912 server's pending command handling. It is also now possible to
5913 execute command reply functions from other command reply
5914 function as the function callbacks for commands and command
5915 replies are one and same. The pending commands are not static
5916 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5917 in client connection context. Thus, pending commands are server
5918 connection specific as it is convenient.
5920 Changed the function silc_client_command_pending and
5921 silc_client_command_pending_del and added new function
5922 silc_client_command_pending_check. Removed the
5923 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5926 * Added cmd_ident, current command identifier, to the client
5927 connection context in lib/silcclient/client.h to keep track on
5928 command identifiers used in command sending. Client's command reply
5929 function handling now supports the mandatory command identifiers.
5931 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5932 funtions in client to fully support pending command callbacks.
5934 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5935 as one of the arguments to the application in the command reply
5938 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5939 before first releasing SILC but came back. Now it is removed again
5940 and should come back nomore. The FORWARDED flag was used only
5941 by the JOINing procedure by forwarding the command packet to router.
5942 Now, the JOINing procedure has been changed to more generic (due
5943 to various router environment issues) and FORWARDED is not needed
5944 anymore for anything. The protocol specification is yet to be
5947 Now, removed silc_server_packet_forward from server and the flag
5948 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5950 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5952 * Renamed NAMES command to USERS command. The NAMES was named that
5953 due to historical reasons. Now it is renamed. Also, rewrote
5954 parts of the USERS command. The nickname list is not sent anymore
5955 by the server. Only Client ID and mode lists are sent in the USERS
5956 command. Changed this also to the protocol specification.
5958 The client now resolves the names and stuff after it receives
5959 the USERS list from the server when joining to the channel.
5961 * WHOIS and IDENTIFY commands has been changed to support multiple
5962 Client ID's per command. One can now search for multiple users
5963 in the network by sending only one WHOIS or IDENTIFY command.
5964 Changed the code and the protocol specifications.
5966 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5967 uses silc_server_command_whois_parse to parse the request. */
5969 * If normal server, do not parse the WHOIS and IDENTIFY requests
5970 before sending it to the router. Saves some time.
5972 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5974 * Fixed JOIN command on client library. Wrong number of arguments
5975 used to crash the client.
5977 * Added silc_server_channel_has_global function to check whether
5978 channel has global users or not.
5980 * Added silc_server_channel_has_local function to check whether channel
5981 has locally connected clients on the channel.
5983 * The silc_server_remove_from_one_channel now checks whether the
5984 channel has global users or not after given client was removed from
5985 the channel. It also checks whether the channel has local clients
5986 on the channel anymore. If it does not have then the channel entry
5987 is removed as it is not needed anymore.
5989 * The silc_server_notify now checks on JOIN notify whether the joining
5990 client is one of locally connected or global. If it is global then
5991 the channel has now global users on the channel and that is marked
5992 to the channel entry. Also, it now saves the global client to
5993 global list who is joining and JOINs it to the channel. This is
5994 for normal server, that is.
5996 Changed silc_server_send_notify_on_channel,
5997 silc_server_packet_relay_to_channel and
5998 silc_server_packet_send_to_channel check if we are normal server
5999 and client has router set (ie. global client) do not send the
6000 message to that client, as it is already routed to our router.
6002 * Implemented LEAVE notify type handling in silc_server_notify
6005 * Tested LEAVE command in router environment successfully. Tested
6006 with two routers, two servers and two clients.
6010 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6012 * Implemented SIGNOFF notify type handling in silc_server_notify
6015 * silc_server_remove_id now removes the client entry from all channels
6016 it has joined and thusly sends SIGNOFF notify type.
6018 * Rewrote the NAMES list generation in server by removing two excess
6019 loops. The lists are created now inside one loop.
6021 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6023 * silc_server_remove_channel_user checks now also global list
6024 for channel and client.
6026 * silc_server_new_channel_user checks now both local and global
6027 list for channel and client. Fixed a bug in client id decoding.
6028 Used to decode wrong buffer.
6030 * silc_server_channel_message checks now both local and global
6031 list for channel entry.
6033 * Tested channel joining (hence JOIN) in router environment
6034 successfully. Tested with two routers, two servers and two
6037 * Tested channel message sending in router environment successfully.
6039 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6041 * Added silc_server_save_channel_key into server.[ch] to save the
6042 received channel key in Channel Key payload processing. It is
6043 also used in JOIN command reply handling.
6045 Equivalent function silc_client_save_channel_key added into
6046 client.[ch] into client library.
6048 * Changed JOIN command reply to send information whether the channel
6049 was created or not (is existing already) and the channel key
6050 payload. Changed protocol specs accordingly.
6052 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6053 the request was sent by ID and not by nickname. Crashed on
6056 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6059 now correctly save the received data.
6061 * silc_server_free_sock_user_data now notifies routers in the
6062 network about entities leaving the network.
6064 At the same time implemented functions silc_server_remove_id
6065 and silc_server_send_remove_id to receive and send REMOVE_ID
6066 packets. The packet is used to notify routers in the network
6067 about leaving entities. The ID removed will become invalid in
6070 * Added function silc_idlist_del_server into server. Removes and
6071 free's server entry from ID list.
6073 * silc_server_private_message function now checks, if we are router,
6074 that the destination ID really is valid ID, naturally.
6076 * In router when NEW_ID packet is received (for new client) the
6077 hash of the Client ID is saved in the ID Cache but the
6078 client->nickname is set to NULL, instead of putting the hash
6081 IDENTIFY command now also checks that client->nickname must be
6082 valid. If it is not if will request the data from the server who
6083 owns the client. Added new function
6084 silc_server_command_identify_check.
6086 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6087 to set the command to already allocated Command Payload.
6089 * Tested private message sending in router environment with two
6090 routers, two servers and two clients. Fixed minor bugs and now
6093 * Fixed segfault from client's NAMES command. Used to crash if
6096 * Forwarded packets must not be routed even if it is not destined
6097 to the receiver. Changed server code comply with this.
6099 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6101 * Added `require_reverse_mapping' boolean value to ServerParams
6102 structure. If TRUE (not default) the server will require that
6103 the connecting host has fully qualified domain name.
6105 If the reverse mapping is not required and hostname could not be
6106 found the IP address is used as hostname.
6108 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6110 * Implemented version string checking to both client and server.
6111 The check is incomplete currently due to the abnormal version
6112 strings used in development version of SILC.
6114 * Changed all command functions in server to use the new
6117 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6119 * Changed char *data to unsigned char *data in ID Cache system to
6120 support binary data as ID Cache data. Changed code to support
6121 binary data in lib/silccore/idcache.c.
6123 * Renamed silc_server_packet_relay_command_reply to
6124 silc_server_command_reply as it is normal packet receiving
6125 function. Rewrote the function to accept command replys for
6126 servers and not only for clients.
6128 * Mark remote router always as registered server if we are connecting
6129 to it. Otherwise, commands sent by the router to us are ignored.
6131 * All ID List find routines now returns the ID Cache Entry pointer
6132 as well if requested.
6134 * WHOIS command works now in router environment, tested with two
6135 routers, two servers and two clients.
6137 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6138 in router environment (as it is almost equivalent to WHOIS) but
6139 hasn't been tested thoroughly. Added new functions:
6141 silc_server_command_identify_parse
6142 silc_server_command_identify_send_reply
6143 silc_server_command_identify_from_client
6144 silc_server_command_identify_from_server
6146 * Disabled route cache adding because adding two different ID's with
6147 same IP replaces the old cache entry thus giving wrong route.
6148 The entry->router->connection is always the fastest route anyway
6149 so route cache may not be needed. Of course, new routes maybe
6150 established after receiving the ID when the entry->router->connection
6151 might not be anymore the most optimal.
6153 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6155 * Add route cache for received ID for fast routing.
6157 * Added silc_server_packet_route to route received packet on router
6158 that is not destined to us.
6160 * Renamed silc_server_get_route to silc_server_route_get.
6162 * Added id_string and id_string_len fields into SilcServer to
6163 include encoded ServerID for fast comparing without excess
6164 encoding of the ID's.
6166 * Cleaned up WHOIS command on server side. Added following static
6169 silc_server_command_whois_parse
6170 silc_server_command_whois_check
6171 silc_server_command_whois_send_reply
6172 silc_server_command_whois_from_client
6173 silc_server_command_whois_from_server
6175 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6176 arguments in command replies. All command functions should be
6177 updated to use this macro.
6179 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6181 * Minor typo fixes on command reply handling on server.
6183 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6185 * Added silc_server_command_add_to_channel internal routine to add
6186 the client to the channel after router has created the channel and
6187 sent command reply to the server.
6189 * Added generic silc_server_send_command to send any command from
6192 * Use static buffer with ID rendering instead of duplicating data.
6194 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6196 * Fixed a channel user mode bug when joining to a channel server gave
6197 everybody channel founder rights, oops.
6199 * We mark ourselves as the router of the incoming server connection
6200 if we are router ourselves. This way we can check in some packet
6201 sending functions whether it is locally connected server. For
6202 incoming router connections we put NULL.
6204 * For router sending packets locally means now always sending the
6205 packet cell wide; to local clients and local servers. For normal
6206 server sending packet locally means sending it to only local
6209 * Fixed the JOIN command to really work in router environment. If the
6210 channel is created it is always created by the router. Router is
6211 also responsible of making the initial joining to the channel,
6212 sending JOIN notify to the sending server and distributing
6213 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6214 does not exist server doesn't do anything else but forward the
6215 command to the router which performs everything.
6217 * Added silc_server_send_channel_key function to send the Channel Key
6220 * Added silc_server_create_channel_key to create new channel key. The
6221 channel key is now re-generated everytime someone joins or leaves
6222 a channel, as protocol dictates. Note: channel->key_len is the
6225 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6227 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6228 packet_receive.[ch] to separate packet sending and receiving
6229 routines. The server.[ch] now includes everything else including
6230 actual packet processing (writing and reading data) and other
6233 Renamed silc_server_private_message_send_internal to
6234 silc_server_send_private_message. The routine is still though
6235 used only to relay private messages as server does not send
6236 private messages itself.
6238 Renamed silc_server_new_channel to silc_server_create_new_channel
6239 and added new function sicl_server_new_channel that handles the
6240 incoming New Channel packet. Added also new sending function
6241 silc_server_send_new_channel to send New Channel Payload.
6243 * Added new function silc_server_notify to process incoming notify
6244 packet to the server/router. Server may then relay the notify
6245 to clients if needed.
6247 * Added new function silc_server_new_channel_user to process incoming
6248 New Channel User packet. Router will redistribute the packet and
6249 send JOIN notify to its local clients and locally connected servers
6250 if needed. Normal server will send JOIN notify to its local client
6251 on same channel when received this packet. Added also corresponding
6252 sending function silc_server_send_new_channel_user to sent the
6255 * Added boolean route argument to send_notif_to_channel and
6256 packet_send_to_channel functions to attempt to route the packet
6257 if it is TRUE and send only locally if it is FALSE.
6259 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6261 * silc_server_replace_id now broadcasts the received replace ID
6262 packet if it is not broadcast packet already. The router must
6263 broadcast to inform other routers about changed ID.
6265 * Added backpointer to server's router into SilcServer context in
6266 silcd/server_internal.h.
6268 * Fixed silc_server_packet_broadcast to send correct broadcast
6271 * The channel key is now distributed to the local client as soon
6272 as it is received from the router (in router environment) so that
6273 no other packet may be sent for the channel until client has
6276 * silc_server_remove_channel_user now broadcasts the received
6277 Remove Channel User packet if it is not broadcast packet already.
6278 The router must broadcast to inform other routers about removed
6281 * Added users field into SilcPacketContext that is a reference count
6282 of the context. One can increase the reference count by calling
6283 silc_packet_context_dup which is now changed to just increase the
6284 reference count instead of duplicating the data. The reference
6285 count is decresed by calling silc_packet_context_free that will
6286 free the data after the reference count hits zero.
6288 For now on the packet context and everything allocated into it
6289 (including the raw packet from network) must be freed by calling
6290 the new silc_packet_context_free function. Added also new function
6291 silc_packet_context_alloc that must be used now to allocate the
6292 context. This also means that if a routine is asynchronous from
6293 silc_[client/server]_packet_parse_type the packet context must
6294 be duplicated by calling silc_packet_context_dup. Otherwise it
6295 gets free'd after silc_[client/server]_packet_parse_type returns.
6296 Also, one must remember that if packet is duplicated then its
6297 reference count must be decresed by calling the free function as
6298 many times as it was duplicated.
6300 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6301 from both client and server.
6303 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6305 * Made joining to a channel working in router environment.
6307 * Cleaned up JOIN command on server side and create function
6308 silc_server_command_join_channel internal routine to make the
6311 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6313 * Changed silc_command_pending list to SilcDList. Also, added
6314 `ident' field to SilcServerCommandPending structure to identify
6315 the reply and to call correct callback.
6317 Added silc_server_command_pending_check function to replace the
6318 corresnponding macro. The silc_command_pending list is not
6321 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6322 to set identifier to previously allocated Command Payload. It
6323 is used to set identifier for command when resending Command
6326 * Added silc_command_payload_encode_payload to encode Command
6327 Payload buffer from SilcCommandPayload structure.
6329 * Added silc_argument_payload_encode_payload to encode Argument
6330 payload buffer from SilcArgumentPayload structure.
6332 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6334 * Changed WHOIS command to support router connection on server side.
6335 The whois request is always sent to router unless the server is
6336 standalone server. After server has received the reply from the
6337 router will it send the reply to the client.
6339 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6340 broadcast received broadcast packet. The function is used only
6341 by router. The broadcast packet is always sent to the router's
6344 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6345 render given ID to printable string, for log files for example.
6347 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6349 * Made basic router to router connections working. At least they
6350 can now connect to each other but nothing really works the way
6351 they are supposed - yet.
6353 * Added new initiator token to RouterConnection configuration
6354 file in silcd/serverconfig.[ch]. It is used to tell whether we
6355 are the initiator to the remote router or whether we'll expect
6356 the other end to connect.
6358 * Moved registering of listener task to silc_server_init, hence
6359 the server starts listenning as soon as it is run, even if it
6360 does not have connections to other routers. Let's see how well
6363 * Changed default connection retry timeouts for more suitable in
6366 * Removed cipher and such arguments from silc_idlist_add_client
6367 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6368 Added new function silc_idlist_add_data to add the keys and stuff
6371 * Added SilcIDListData structure and added it to SilcClientEntry
6372 and SilcServerEntry as their first field in the structure. This
6373 way we can explicitly cast the ID entries to the SilcIDListData
6374 structure and get common data for the entries. In past, we had
6375 to first check what type of connection it is and then cast it to
6376 correct ID entry type. Now, we can directly cast the opaque
6377 pointer to the SilcIDListData (no matter what ID entry it actually
6378 is) and get the data needed.
6380 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6382 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6383 in some circumstances even if threre were timeout tasks, though not
6384 IO tasks, but tasks anyway. Now fixed.
6386 * Defined SilcServerConnection structure to hold connection specific
6387 stuff about directly connected servers and routers. The definition
6388 is currently in silcd/server_internal.h. I thought about having
6389 a bit more important role fro this struct but for now it is used
6390 only when connecting to other server (or router actually).
6392 * Added connecting retry support in server when connecting to
6393 router(s). The retry feature implement exponential backoff
6394 algorithm. Also, added SilcServerParams structure to hold default
6395 parameters for server. For now, it include these retry settings
6396 and are hard coded. After server is moded to be as Silc Server
6397 Library this structure will be more important.
6399 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6401 * Changed client librarys channel->clients table to SilcList and
6402 changed code accordingly.
6404 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6406 * Changed client's channel table to SilcList and changed code
6407 accordingly. Also changed SilcChannelClientEntry to include back-
6408 pointer to the channel so that client entry can use that structure
6409 as list as well and we have fast cross-reference to the channel.
6410 This change dramatically decreased the complexity of channel
6411 handling with client entry and vice versa (removed one extra
6412 loop when searching for channel entry from many functions).
6414 * Changed server->sim from table to SilcDList and changed code
6417 * NAMES command can now be used from user interface. It will show
6418 the user list on the channel, neatly.
6420 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6421 Code now saves realname of the user if it becomes available.
6423 * Renamed configure.in to configure.in.pre and made ./prepare
6424 script to automatically add correct version string to
6425 configure.in which it creates from configure.in.pre.
6427 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6429 * NAMES command reply now shows users mode with the nickname when
6432 * Moved silc_client_ch[u]mode[_char] functions from
6433 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6434 place sucks, they are utility functions and should be in some
6437 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6439 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6442 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6446 * Added TRQ (efficient deque and list library) into lib/trq. This is
6447 a very good list library that is currently used in the SILC. Defined
6448 SilcList API over the library because I didn't like the API very
6449 much. See lib/trq/silclist.h for the API and examples of how to
6450 use the API. Fixed various places in the code to use the new
6451 SilcList API. The SilcList is meant for lists that has a structure
6452 already defined as a list. It is not suitable to add just some
6453 context to the list (in TRQ, the context is the list actually).
6455 So, I defined SilcDList that can be used for the purpose where
6456 predefined list structure does not exit. This can be used as
6457 such list. Now some context just can be added to the SilcDList.
6458 Currently this list is not used in the SILC just yet, though there
6459 are a lot places where this can replace dynamically allocated
6460 tables and I will fix these places, later, to use SilcDList.
6461 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6462 and use TRQ internally).
6464 Also fixed some annoying warning messages that the original TRQ
6465 code generated. Also minor changes to TRQ's Makefile.in.
6467 * Added support for querying by Client ID to both WHOIS and
6468 IDENTIFY commands into server, as required by the protocol.
6470 * Removed method function pointers from SilcBuffer structure. They
6471 weren't used to anything and just increased the context size for
6472 no good reason. This change also made silc_buffer_alloc and
6473 silc_buffer_free functions inline functions.
6475 * Disabled command flooding detection support until it's fixed so
6476 that it accepts commands in but does not execute them more than once
6479 * Added silc_net_localhost(), to return local hostname, into
6480 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6481 that must be initialized before calling silc_client_init.
6483 * Added new function: silc_server_send_notify_on_channels to send
6484 notify messages to all channels client has joined. It is assured
6485 that the message is sent only once per client.
6487 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6488 lib/silcutil/silcutil.[ch] as silc_format function. The new
6489 function is generic and is used by server as well, not only by
6490 the logging routines.
6492 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6493 the provided version string was not acceptable. Added new function:
6494 silc_ske_check_version into lib/silcske/silcske.h. The function
6495 must be implemented by the application (client or server) and it
6496 does not reside in the SKE library. The function checks the version
6497 string remote end sent.
6499 * Added back pointers (to opaque context and to SilcSocketConnection)
6500 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6502 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6503 duplicate packet context structure.
6505 * Changed `notify' client operation to send same arguments as client
6506 receives from server except for ID's. ID's are mapped to correct
6507 ID entry and that is returned. Also, if channel entry is not sent
6508 by server but the notify is for channel the channel entry is sent
6509 to application (otherwise application doesn't know that it is for
6510 channel (library gets it from packet's Destination ID)).
6512 * Added silc_client_remove_from_channels into client library to
6513 remove a client from all channels it has joined to. Used when
6514 received SIGNOFF notify from server. Added also new function
6515 silc_client_replace_from_channels to replace old ID entry with
6516 new ID entry on all channels. Used when received NICK_CHANGE
6519 * Fixed ID Cache list handling in silc_idlist_get_client in
6520 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6521 to get (or query) client by ID.
6523 * Updated TODO list.
6525 * Added connection authentication status message defined by the
6526 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6527 support for these into the code in client and server side.
6529 * Added generic function silc_client_send_command to send any command
6530 with variable argument list. Application should use this function
6531 to send commands if the command functions provided by the library
6532 does not suite for the application's user interface needs.
6534 * Added new `failure' client operation. Application is notified about
6535 received failure packet if client is executing a protocol. In this
6536 case the protocol's execution has failed.
6538 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6539 is required by the protocol.
6541 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6542 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6545 * Added status flag to SilcSKE object to indicate realtime status
6546 of the SKE protocol.
6548 * Application receives now exactly same command reply arguments as
6549 the library receives from server. However, if ID is received the
6550 corresponding ID entry is returned to the application (eg. Client
6551 ID is mapped to correct SilcClientEntry entry and that is returned).
6552 Changed command_reply client operation due to this change.
6554 * Changed all ID's in commands and in command replys as ID Payloads.
6555 Change affected both client and server side codes.
6557 All ID's sent in SILC network (with execption of ID's in SILC
6558 Packet header) are sent in ID Payload to support variable length
6561 * Server now notifies nick changes and notifies all clients on
6562 the channels about the new nickname (about the new Client ID,
6565 * Implemented CMODE command to change channel modes. Supports all
6566 channel modes defined by the protocol specs except ban and invite
6567 lists. (Also, private channel key mode is supported but support for
6568 setting private channel key in client is missing, thus, this mode
6569 has no effect on client side (except that server requires that the
6570 client uses private channel key and normal channel traffic does not
6573 Also, invite mode works per se, but INVITE command does not work
6574 yet correctly, so you can set channel as invite only channel but
6575 inviting clients to the channel does not work (it is yet to be
6576 thought what's the best way to do it).
6578 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6579 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6580 Implemented CUMODE command to change user's mode on the channel.
6581 Supports all modes defined by the protocol specs.
6583 * Added NAMES command reply to return users modes on the channel.
6585 * Removed unnecessary and slow ciphers from lib/silccrypt.
6587 * Set SO_KEEPALIVE option to connection sockets by default.
6589 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6591 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6592 redefined the Notify Payload into protocol specs.
6594 * Added silc_id_payload_parse_id to get ID directly from raw
6597 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6599 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6600 accept searching by Client ID as well.
6602 * Added support for LEAVE and SIGNOFF notify types in client library.
6604 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6605 to parse ID Payload from raw data.
6607 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6609 * Added flags parameter into silc_ske_assemble_security_properties
6610 function in lib/silcske/silcske.[ch].
6612 * Changed notify client operation to fit better for notify messages
6613 sent by server. The notify payload received from server is now
6614 passed to the application (after parsing it to SilcNotifyPayload).
6615 It is application's responsibility to retrieve the arguments
6616 from the payload and show the message the way it wants. The message
6617 sent by server is implementation specific.
6619 * Changed public keys to comply with the protocol specification.
6620 Old public keys are not supported anymore and are not compatible.
6622 * Removed nickname from Channel Payload as the latest draft removed
6623 it. The client must resolve the nickname from the NAMES command
6624 reply received when it joined the channel.
6626 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6628 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6630 * Fixed some errors in protocol specification drafts.
6632 * Created lib/silccore/silcnotify.c to implement Notify Payload
6633 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6634 generic payloads described by protocol specifications. The file
6635 includes implementations for ID Payload and Argument Payload.
6637 * Changed Command Payload implementation to use the new Argument
6638 Payload. Changed command_xxxx_payload to command_payload_xxxx
6639 to comply with SILC coding conventions.
6641 * Added suppport for Argument Payload handling in Notify Payload
6642 implementation as protocol requires it. Added the new support
6643 into server and client lib as well.
6645 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6647 * Added support for multiple nicknames on same channel. [n] is
6648 added locally to the nickname if there are more than one same
6649 nicknames on the channel.
6651 * Server now sends all nicknames that matched WHOIS request.
6652 Client also shows the list received from server.
6654 * Added TOPIC command to client side. User can now set and show
6655 current topic on channel.
6657 * Added MOTD command to client and server. Also, server sends the
6658 motd when client connects to the server.
6660 * Changed version strings to comply ISO 8601.
6662 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6664 * Fixed protocol error handling in client library. It should now
6665 cope even if the SKE fails for some reason.
6667 * Made new protocol specification drafts for submitting to IETF.
6669 * Implemented TOPIC command to server in silcd/command.c.
6671 * Added two new notify types into lib/silccore/silcnotify.h:
6672 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6673 notify nickname change and topic setting/change on a channel.
6675 * API change of command_reply operation in client library. The
6676 application gets now the status type received from server as well.
6678 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6682 * Cras fixed and optimized the packet handling even further and
6683 it should work now. Minor change to the prototype of function
6684 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6686 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6688 * Added new function into lib/silcutil/silcschedule.[ch]:
6689 silc_schedule_with_fd to select() a specified fd. The function
6690 returns after timeout expires or data arrives or goes. The
6691 function is used by packet routines to wait that all data is
6692 received from network.
6694 * Fixed data reading from network in lib/silccore/silcpacket.c.
6695 The code now assures that all data is read from the fd and then
6696 continues packet processing. This was a bug fix since the code
6697 used to drop some data in some circumstances.
6699 * Added new function into lib/silcclient/client.[ch]:
6700 silc_client_start_key_exchange to start key exchange after
6701 connection has been established to server. The code internally
6702 now uses this funtion but its main purpose was to provide it
6703 for applications that perform their own connecting. After
6704 application has created a connection it merely calls this
6705 function to start the key exchange between client and server.
6706 The library takes care of everything else after that.
6708 Updated also lib/silcclient/README to explain the usage of
6711 * Do not send to application information that connection has
6712 been established. Application gets notified it by connect
6715 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6717 * Applied cras's patch to add silc_schedule_one function. The
6718 function runs scheduler once and returns.
6720 * Fixed the scheduler after cras messed it up. The timeout
6721 handling works now as it's supposed to work.
6723 * Added into lib/silccore/ silcnotify.h to include notify
6724 message types support. Changed silc_server_send_notify*
6725 functions, in server.[ch], to support those new notify types.
6726 Added the support for the notify types into client library,
6727 as well. Added new notify client operation into ops.h in
6730 * Changed silc_server_packet_send_to_channel to send normal
6731 packets instead of just channel message packets. The function
6732 is now used to send the notify packets to channels. It is not
6733 used to send channel message packets anymore, as server never
6736 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6737 va_arg()s as it seems to require it nowadays. I guess, if SILC
6738 is compiled with older va_arg() the new code should work anyway.
6740 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6742 * Splitted core library. Core library (lib/silccore) includes
6743 now only SILC protocol specific core (and common) components.
6744 Created new utility library (lib/silcutil) that includes more
6745 generic purpose stuff. The stuff for util library was taken
6746 from the old core library. This was minor and easy split.
6748 * Created SILC Client Library (lib/silcclient) that includes
6749 implementation of the SILC client without user interface. This
6750 was major move from silc/ directory. The code has been changed
6751 so that it is transparent towards the user interface. The
6752 silc/ directory includes now the same user interface as before
6753 and it uses the new client library. Read lib/silcclient/README.
6754 Basicly, the client library performs everything else related
6755 to SILC except user interface handling. Also, configuration
6756 files are considered to be part of user interface and library
6757 does not handle them.
6759 This change also changed a lot of structures, function naming etc.
6760 Most important change was that SilcClientWindow object was
6761 renamed to SilcClientConnection in the client library. Created
6762 also new file lib/silcclient/ops.h. Also added new files
6763 silc/local_command.[ch] and silc/client_ops.[ch].
6765 All these changes were made to make it easier for user interface
6766 designers to create what ever user interface for the SILC client
6769 It is also expected that the server will be moved to lib
6770 directory as well and SILC Server Library will be created;
6771 sometimes in the future.
6773 * Removed Local commands from lib/silccore/silccommand.h as
6774 they are application specific and new client library does not
6775 handle any of those anymore.
6777 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6778 old client implementation in silc/.
6780 * Added support for callback functions in SILC_LOG_* macros.
6781 Application can now set its own callbacks that will be called
6782 instead of using the default functions that will always print
6783 the debug messages to stderr (or stdout). Also, debugging can
6784 now be disabled by setting silc_debug to FALSE and re-enabled by
6785 setting it to TRUE. Note, that logging will still work even
6786 if debugging is disabled.
6788 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6789 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6790 silc_log_reset_debug_callbacks.
6792 * To enable debugging in silc client one must give now -d
6793 option on command line.
6795 * Changed silc_schedule_init to automatically allocate task queues
6796 if they are not allocated before calling it.
6798 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6800 * Added GMP 3.1 into math library.
6802 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6804 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6805 a channel in SILC network. The packet is used by servers and
6806 routers to notify other routers that user has left a channel.
6807 This little feature was missing until now. Added the feature
6808 to protocol specification as well.
6810 Added functions: silc_server_send_remove_channel_user and
6811 silc_server_remove_channel_user into server.[ch].
6813 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6814 lib/silccore/silcpacket.h. However, they are not implemented
6817 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6819 * Fixed joining to a channel and sending channel messages
6820 between server and router. The channel message sending should
6821 now work inside a cell.
6823 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6825 * Fixed the private message sending between server and router.
6826 The private message sending should now work inside a cell.
6828 * Added silc_server_replace_id into server.[ch] to replace
6829 existing ID in the SILC network.
6831 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6832 and silc_idlist_replace_server_id into idlist.[ch] in server.
6834 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6836 * Fixed the server to server connections. Server can again now
6837 connect to router. Router to router connections probably does
6840 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6842 * Added dynamic protocol registering support. Now protocols can
6843 registered and unregistered on the fly. Patch by cras.
6845 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6847 * Added lib/contrib directory to hold routines that some platforms
6848 don't have but are needed by SILC.
6850 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6851 into lin/contrib to provide getopt() and getopt_long() for
6852 those who don't have it.
6854 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6856 * Added AWAY command to client. When away message is set and
6857 client receives a private message packet the client automatically
6858 replies to the sender with the away message.
6860 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6861 bug seemed to be the cause of recent problems when compiling
6864 * Added version detection support to SKE protocol specification
6865 and added the new changes to the SKE implementation as well.
6866 There were other minor changes in the SKE protocol as well.
6868 Many changes in lib/silcske/silcske.[ch] and in
6869 lib/silcske/payload.[ch].
6871 * Added ^U functionality, clear input line. Patch from cras.
6873 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6875 * Mainly small bugfixes on core library. Fixed some debugging
6876 logging and buffer overflow in silclog.c.
6878 * Updated config.sub and config.guess on the distribution tree.
6880 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6882 * Added command lagging support in server. Client may execute
6883 commands now only once in two seconds.
6885 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6887 * Optimized packet reception. MAC computation and checking is now
6888 also more optimized. A lot previously duplicated code is now
6889 used as generic by both client and server.
6891 * Fixed key pair generation in clientutil.c
6893 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6895 * Added into lib/silccore/silcbufutil.[ch] new function;
6896 silc_buffer_realloc.
6898 * Moved generic packet sending/encryption functions to
6899 lib/silccore/silcpacket.[ch] from client and server. Some
6900 rewriting of the functions.
6902 * Moved all generic packet reception/decryption functions to
6903 lib/silccore/silcpacket.[ch] from client and server. The
6904 packet processing is now much cleaner in both client and server.
6905 These were major changes in both client and server.
6907 * Created many common functions in server to do packet sending.
6908 Previously code were duplicated a lot, this has been removed
6911 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6913 * Rewrote major parts of the ID cache system. Don't know
6914 whether it is better now or not but at least the API is more
6917 * Major rewrite on ID cache stuff on client because of the ID
6918 cache API changes. Added idlist.c to client.
6920 * Also major rewrite on ID cache stuff on server as well.
6921 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6922 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6923 in hand, instead they are all put into the ID cache system now.
6924 All server_idlist_* routines uses ID cache now instead of
6925 traversing its own lists (those lists does not exist anymore).
6926 SilcIDList though still exists. Also, SilcXXXEntry's are
6929 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6931 * Finally made the SKE implementation compliant to the protocol
6932 specification. All mp integers are now binary encoded as
6933 opposed being HEX encoded.
6935 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6938 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6939 functions: silc_[encode/decode]_pem. Also added function
6940 silc_encode_pem_file to PEM encode with newlines ('\n') for
6943 * SILC public keys are now encoded either PEM or binary. Same
6944 option is for private keys as well. By default private keys
6945 are binary encoded and public keys PEM encoded. Silly HEX
6946 encoding were removed.
6948 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6949 function to create fingerprints.
6951 * Fixed a bug in SHA1; does not change the original data anymore.
6953 * Partly implemented INFO command on client and server side.
6954 Fixed CLEAR command. Changes to SERVER command; show current
6955 server(s) when giving command without arguments. Added
6956 VERSION command to client.
6958 * Added check to server that unregistered connections cannot
6959 execute commands (unless it is specificly allowed).
6961 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6963 * Fixed screen refresh.
6965 * Fixed channel joining bug from client. On some circumstances
6966 client tried to join to a channel it had already joined.
6968 * Added public key verification process into client's protocol.c.
6969 The client now verifies the public key from user and saves
6970 it into ~./silc/serverkeys/ directory.
6972 Added into: clientutil.[ch]: silc_client_verify_server_key.
6974 * Changed SKE protocol's silc_ske_initiator_finish function
6975 to accept callback function that verifies the received public
6976 key. Removed old silc_ske_verify_public_key function.
6978 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6980 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6981 silc_pkcs_private_key[_data]_set.
6983 * Made the password and public authentication more cleaner in
6984 server's protocol.c.
6986 * Removed historic and obsolete protocol `channel_auth' from
6987 both client and server.
6989 * Removed wrong way of sending command status messages from
6990 server to client in server's command.c. The old way violated
6991 protocol specification.
6993 Changes to silccore/silccommand.[ch]: removed
6994 silc_command_encode_status_payload -> not needed anymore,
6995 changed silc_command_encode_payload_va to accept extra
6996 argument on variable argument list. The argument type must
6997 now be provided to the function. Also, added new function:
6998 silc_command_encode_reply_payload_va which is same as
6999 normal command_encode_payload_va except command status type
7000 is provided as extra argument.
7002 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7004 * Added ~./silc directory handling. The directory includes the
7005 public and private keys for the client.
7007 Added silc_client_check_silc_dir, silc_client_create_identifier
7008 and silc_client_load_keys.
7010 * Implemented SILC protocol compliant public key. Added public
