4 Payload. Affected file lib/silccore/silcchannel.c.
6 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
8 * Fixed CUMODE_CHANGE notify handling to change the mode of
9 correct client. Affected file lib/silcclient/client_notify.c.
11 * Make silc_rng_alloc fail if it cannot allocate the sha1
12 hash algorithm. Affected file lib/silccrypt/silcrng.c.
14 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
16 * Fixed the file transfer's key agreement payload to include
17 zero port also if the hostname is NULL because it could not
20 Call file transfer monitor callback now also if error occurs
21 during key agreement protocol.
23 Changed the silc_client_file_send interface to return the
24 SilcClientFileError instead of session id. The session ID
25 is returned into pointer provided as argument.
27 Check that the file exists locally before sending the
28 file transfer request at all.
30 Affected file lib/silcclient/client_ftp.c, silcapi.h.
32 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
33 error than can occur while key agreement protocol. Affected
34 file lib/silcclient/silcapi.h.

37 is changed and +k mode is set in the channel. Affected file
38 irssi/src/silc/core/silc-channels.c.
40 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
41 SILC_LOG_WARNING to give out Warning and not Error. Affected
42 file lib/silcutil/silclog.c.
44 * Fixed the channel message payload decryption in the function
45 silc_channel_message_payload_decrypt to not modify the original
46 buffer before it is verified that the message decrypted
47 correctly. Otherwise, next time it is called with correct
48 channel key it won't encrypt since the payload is corrupted.
49 Affected file lib/silccore/silcchannel.c.
51 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
53 * Do not constantly resize the window. A fix patch by cras.
54 Affected file irssi/src/fe-text/screen.c.
56 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
58 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
59 Affected file lib/silcutil/silcnet.c.
61 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
63 * Fixed a bug in hash table internal routine for traversing
64 the table with foreach callback. The current entry may
65 become invalid in the callback but it was referenced after
66 the callback returned.
68 Do not allow auto rehashing of hash table during the
69 silc_hash_table_foreach operation, for same reasons as it is
70 not allowed for SilcHashTableList. Affected files are
71 lib/silcutil/silchashtable.[ch].
73 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
75 * Defined DLLAPI into silcincludes.h and silcwin32.h for
76 Win32 DLL. extern's in header files are now declared with
79 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
81 * Fixed private message handling. It used some old code that
82 caused the client to crash. Affecte file is
83 lib/silcclient/client_prvmsg.c.
85 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
87 * Added function silc_client_add_channel,
88 silc_client_replace_channel_id, and removed functions
89 silc_client_new_channel_id and silc_idlist_get_channel_by_id
92 * Added cross reference of the joined channels to the
93 SilcClientEntry, and changed the SilcChannelEntry's
94 users list to SilcHashTable. The affected files are
95 lib/silcclient/idlist.[ch].
97 * Fixed a bug in hash table tarversing. While the hash table
98 is traversed with SilcHashTableList the table must not be
99 rehashed. It is now guaranteed that auto rehashable tables
100 are not rehashed while tarversing the list. Also defined that
101 silc_hash_table_rehash must not be called while tarversing
102 the table. Added function silc_hash_table_list_reset that must
103 be called after the tarversing is over. The affected files are
104 lib/silcutil/silchashtable.[ch].
106 * Changed all hash table traversing to call the new
107 silc_hash_table_list_reset in server and in client library.
109 * Added function silc_client_on_channel to return the
110 SilcChannelUser entry if the specified client entry is joined
111 on the specified channel. This is exported to application as
112 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
114 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
116 * Fixed founder regaining problem with JOIN command on normal
117 server. The notify for mode change must be sent always and
118 not only if !cmd->pending. Affected file silcd/command.c.
120 * Fixed the WHOWAS command's reply sending to support the
121 lists correctly. Affected file silcd/command.c.
123 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
125 * When sending JOIN command to router for processing the
126 sender's old command identifier was not saved back to the
127 sender's command context, fixed now. The affected file is
130 * Create the key in JOIN command of the router did not return
131 the channel key, added check for this. Affected file is
134 * Fixed a channel ID update bug in JOIN command reply. Do
135 not directly upgrade the ID but call the function
136 silc_idlist_replace_channel_id if the ID was changed.
137 Affected file silcd/command_reply.c.
139 * Fixed memory leaks from command calling if it would fail.
140 Affected file silcd/command.c.
142 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
144 * Applied patches from cras:
146 Memory leak fixes around libaries, irssi window resize fix,
147 new silclist.h and silcdlist.h, all extern inline changed to
150 * Removed dotconf from lib/dotconf, not needed anymore.
152 * Removed TRQ from lib/trq, not needed anymore.
154 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
155 with server connections. Later this will be configurable
156 in config file after new config file is done. Affected file
159 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
161 * Fixed a crash in server related to channel announcements.
162 Affected file silcd/server.c.
164 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
166 * Fixed memory leaks in silc_server_create_new_channel*
167 functions. Affected file silcd/server.c.
169 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
170 which ID was changed. This way the router will send the
171 user list for the channel again, and server won't be in
172 desync in some rare circumstances. Affected file is
173 silcd/packet_receive.c.
175 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
177 * Check for NULL socket pointer in the function
178 silc_server_packet_send_to_channel_real. Affected file
181 * Fixed the BAN notify handling to correctly remove ban
182 list. Affected file silcd/packet_receive.c.
184 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
186 * Fixed some header addition to Toolkit distribution in
187 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
189 * Added lib/silcclient/client_ops_example.h as an template
190 file for application programmers to quickly start using
191 the SilcClientOperation functions in their application.
192 Updated the lib/silcclient/README as well to tell about this
193 nice file made available.
195 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
197 * Call silc_server_remove_from_channels when removing client
198 entry when NO_SUCH_CLIENT_ID was received. Affected file
199 is silcd/command_reply.c.
201 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
203 * Added server & router operator statistics updating. Affected
204 file silcd/packet_receive.c and silcd/command.c.
206 * Fixed the SERVER_SIGNOFF notify handling on normal server
207 not to save the history information for clients. Same was
208 fixed earlier in remove_clients_by_server function, but not
209 here. Affected file silcd/packet_receive.c.
211 * Raised the default connection-retry count from 4 to 7 in
212 server. Affected file silcd/server.h.
214 * Cancel any possible reconnect timeouts when we start the
215 key exchange. Affected file silcd/server.c.
217 * Do not reconnect on connection failure when SCONNECT was
218 given. Affected files silcd/server.[ch].
220 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
222 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
224 * Fixed the NICK command to always give the unformatted
225 nickname to the one giving the NICK command. If unformatted
226 nickname is cached already it will be formatted and the
227 local entry will always get the unformatted nickname.
228 Affected file lib/silcclient/idlist.c.
230 * Fixed some double frees from client library commands.
231 Affected file is lib/silcclient/command.c.
233 * Fixed CUMODE command in server to assure that no one can
234 change founder's mode than the founder itself, there was a
235 little bug. Affected file silcd/command.c.
237 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
239 * Removed the SilcClientCommandDestructor from the client
240 libary, it is not needed anymore. Affected files are
241 lib/silcclient/silcapi.h, command[_reply].[ch],
242 client_notify, idlist.c.
244 * Fixed GETKEY command to first resolve client, and then
245 resolve the server only if the client was not found, instead
246 of resolving both at the same time. Affected file is
247 lib/silcclient/command.c.
249 * Added silc_client_start_key_exchange_cb and lookup the
250 remote hostname and IP address before starting the key
251 exchange with server. The affected file is
252 lib/silcclient/client.c.
254 * The server's public key is now saved using the IP address
255 of the server and not the servername for the filename.
256 The hostname public key filename is checked as an fall back
257 method if the IP address based filename is not found.
259 Fixed the GETKEY command to save the fetched server key
262 Print the remote server's hostname now when new key is
263 received during connection process. Affected file is
264 irssi/src/silc/core/client_ops.c.
266 * Return always our own public key to the client if it asks
267 for it with GETKEY command. Affected file silcd/command.c.
269 * Removed the use_auto_addr variable from default config
270 file since it was in wrong section. Affected file is
273 * Fixed TOPIC_CHANGE notification to not route it when it
274 was sent using silc_server_send_notify_to_channel function.
275 Affected file silcd/command.c.
277 * Fixed silc_server_send_notify_kicked to send the kicker's
278 Client ID also, it was missing. Affected files are
279 silcd/command.c, silcd/packet_send.[ch].
281 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
283 * Do not save client history information in SERVER_SIGNOFF.
284 Fixes the bug in normal server that it does not detect
285 the client becoming valid after the server becomes back
286 online. Affected file silcd/server_util.c.
288 * Added `sock_error' field into the SilcSocketConnection
289 context. When error occurs during socket operation (read
290 or write) the error is saved. Added also new function
291 silc_socket_get_error to return human readable socket error
292 message. Affected files are lib/silcutil/silcsockconn.[ch],
293 lib/silcutil/unix/silcunixsockconn.c, and
294 lib/silcutil/win32/silcwin32sockconn.c.
296 * The server now prints the socket error message in the
297 signoff for client. Affected file silcd/server.c.
299 * Fixed the `created' channel information sending from router
300 to server in JOIN command. Checks now whether the channel
301 really was created or not and set it according that.
303 Fixed the JOIN command to use the client entry's current
304 ID during the joining procedure instead of the one it sent
305 in the command (it is checked though), since it can change
306 between the packet processing and command processing, and
307 would just case unnecessary pain in the client end. Affected
308 file silcd/command.c.
310 * Fixed a channel key payload sending to use correct channel
311 ID when the server was forced to change the channel's ID by
312 router. Router sent the key payload with the old Channel ID.
313 Affected file silcd/packet_receive.c.
315 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
317 * Call silc_server_save_channel_key only if the key payload
318 was provided in the JOIN command's command reply. Affected
319 file silcd/command_reply.c.
321 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
323 * Fixed silc_mp_sizeinbase to return the value correctly with
324 MPI. Affected file lib/silcmath/mp_mpi.c.
326 * Fixed the stop_server signal to correctly stop the scheduler
327 and gracefully stop the server when SIGTERM or SIGINT signals
328 are received. Affected file silcd/silcd.c.
330 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
332 * Simple handling of TERM and HUP signals. Also added some log
333 flushing call around. Affected file is
336 * Fixed small bugs in silclog.c. Now buffering output will take
337 effect after 10 seconds since startup: This will ensure that
338 no important startup messages are lost. Also output redirection
339 will preserve original format ([Date] [Type] message).
340 Affected file is lib/silcutil/silclog.c.
342 * Added two options to the config file, in the logging section:
343 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
344 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
346 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
348 * Do not print the warning about log files not being initialized
349 more than once to avoid excess logging. Affected file is
350 lib/silcutil/silclog.c.
352 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
353 the SIM copying in make install in Makefile.am.pre.
355 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
357 * Rewritten silclog APIs. Globally interesting changes follows:
358 silc_log_set_files() changed to silc_log_set_file().
359 silc_log_set_callbacks() changed to silc_log_set_callback().
360 ROBOdoc documented silclog header file.
361 SilcLogCb now returns bool to wether inihibit the default
362 handler or not (to keep the old behaviour return always TRUE).
363 The new APIs should also fix the problem of the
364 silcd_error.log file that was written in the current directory.
367 Log files streams will remain opened after silc_log_set_file()
368 call, means less CPU usage notably on high traffic servers.
369 File streams are now full buffered, and flushed to the disk
370 every 5 minutes, lesses HD activity and CPU usage.
371 Messages can be redirected, allowing admins to configure
372 one single logfile for all server messages.
373 the silc_log_quick global variable to activate fast-logging.
374 Affected files lib/silcutil/silclog.[ch]
376 * Changed some code to conform new silclog APIs. Affected
377 files are doc/example_silcd.conf.in, silcd/server.c
378 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
381 * Fixed a memory leak that could occur in some situations.
382 Affected file silcd/serverconfig.c.
384 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
386 * Added the silc_client_del_client to remove the client from
387 all channels as well. Affected file lib/silcclient/idlist.c.
389 * Fixed the client library to correctly remove the client
390 from all channels when the client entry is being destroyed.
391 Affected file lib/silcclient/client_notify.c, command.c.
393 * Added auto-nicking support to the client library. If the
394 applicatio now sets client->nickname it will be sent to the
395 server after connecting by the library. This way for example
396 SILCNICK (or IRCNICK) environment variables will have effect
397 and always change the nickname automatically to whatever
398 it is wanted. Affected file lib/silcclient/client.[ch].
400 * Renamed silc_server_command_bad_chars to the
401 silc_server_name_bad_chars and moved it to the
402 silcd/server_util.[ch]. Added also new function
403 silc_server_name_modify_bad to return nickname that
404 includes bad characters as new nickname without those
405 bad characters. This check and modify is now used in
406 silc_server_new_client when the username is initially set
407 as nickname, so it must be checked to be valid nickname.
408 Affected file silcd/packet_receive.c.
410 * The nickname length is now taken from the packet for real
411 and not trusted to strlen() since it clearly can return
412 wrong length for nickname including bad characters. This
413 also applies to channel names. Affected file silcd/command.c.
415 * Removed the lib/silcsilm/modules directory. Modules are now
416 compiled into the lib/silcsim. Fixed the copying of the
417 modules to follow symbolic links in Makefile.am.pre.
419 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
421 * Fixed silc_string_regexify list creation. Fixes bugs with
422 BAN and INVITE commands in server. The affected file is
423 lib/silcutil/unix/silcunixutil.c.
425 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
427 * Removed the command destructor entirely from the server's
428 command and command reply routines. It is not needed, and
429 its usage was buggy and caused crashes. Affected files are
430 silcd/command[_reply].[ch].
432 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
434 * Cancel protocol and NULL sock->protocol if timeout
435 occurred during protocol. Affected file silcd/server.c.
437 * Cancel protocol timeouts always before calling the final
438 callback, to assure that after final callback is called
439 no other state will be called for the protocol anymore.
440 Affected file silcd/protocol.c.
442 * Print error log if incoming connection configuration could
443 not be found. Affected file silcd/server.c.
445 * Fixed JOIN command to correctly save the founder mode
446 to the client on normal SILC server, when the channel
447 was created by the router. Affected file silcd/command.c.
449 * Fixed LIST command (hopefully) to send correct reply
450 packets. Affected file silcd/command.c.
452 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
454 * The silc_packet_receive_process now returns FALSE if the
455 read data was invalid packet, and TRUE if it was ok.
457 The server now checks that if unauthenticated connection
458 sends data and its processing fails the server will close
459 the connection since it could be a malicious flooder.
461 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
463 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
465 * Make sure the warning about error opening a log file is
466 printed only once and not everytime it fails (produces
467 too much useless log). Affected file lib/silcutil/silclog.c.
469 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
471 * Made the silc_server_daemonise() function more readable.
472 Affected file silcd/server.c.
474 * Pid file is now optional, the user may comment it out from
475 the config file. Removed define SILC_SERVER_PID_FILE, we
476 don't need a default any longer. Affected file
477 configure.in.pre, lib/Makefile.am.pre.
479 * Make some use of the pid file. The server now dies at startup
480 if it detects a valid pid file on his path. The server would
481 die anyway in this circumstance, because of the bind() failure.
482 Affected file silcd/silcd.c.
484 * No longer compiling lib/dotconf.
486 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
488 * Fixed JOIN command parsing not to crash. Affected file
489 lib/silcclient/command.c.
491 * Fied the NICK_CHANGE notify to add the new client entry
492 even it is resolved. This removes an <[unknown]> nick
493 thingy bug in the client. Affected file is
494 lib/silcclient/client_notify.c.
496 * Do not try to allocate 0 bytes (efence does not like it)
497 in lib/silccore/silccomand.c when encoding payload.
499 * Do not take IRCNICK as nickname in Irssi SILC client since
500 it is not possible to set nickname before hand connecting
501 the server (TODO has an entry about adding auto-nicking
504 * Changed the silc_server_command_pending to check whether
505 there already exists an pending entry with the specified
506 command, command identifier and pending callback. This is
507 to fix IDENTIFY and WHOIS related crashes that may register
508 multiple pending commands with same identifier. Affected
509 file silcd/command.c.
511 * Fixed the server to reconnect to the router even if it
512 was already reconnecting and EOF was received. This to
513 fix a possibility that the server wouldn't ever try to
514 auto-reconnect to the router. Affected file silcd/server.c.
516 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
518 * Fixed the server's password authentication to use the
519 length of the locally saved password, and not the one
520 sent in the packet. Affected file silcd/protocol.c.
522 * Fixed same password authentication problem in the
523 Authentication Payload handling routines in
524 lib/silccore/silcauth.c.
526 * Yet another password authentication problem fixed with
527 channel password handling in silcd/command.c.
529 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
531 * If first character of string in silc_parse_userfqdn is '@'
532 then do not parse it. Affected file is
533 lib/silcutil/silcutil.c.
535 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
537 * Fixed minor bug in IDENTIFY command reply sending, which
538 caused various weird problems during JOIN when it was
539 resolving names for users. Affected file silcd/command.c.
541 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
543 * Fixed the IDENTIFY command reply sending to chech better valid
544 clients. It was possible to send incomplete list of replies.
545 Affected file silcd/command.c.
547 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
549 * Added silc_client_command[s]_[un]register functions now to
550 dynamically register the commands in client library. Removed
551 the static table of commands. This allows the client library
552 to call commands without causing the application to know about
553 what commands library has called.
555 Removed the INFO command reply kludge to detect when the command
556 was called by library. Now library use its own command reply
557 function for INFO command.
559 Added function silc_client_command_call to call a command.
560 Application can use it to call command, not access the structure
563 Now all commands that are sent by the client library (not
564 explicitly sent by application) use own command reply functions.
566 Affected files around lib/silcclient/ and in
567 irssi/src/silc/core/.
569 * Fixed the WHOIS command reply sending to chech better valid
570 clients. It was possible to send incomplete list of replies.
572 Fixed the WHOIS and IDENTIFY to send the request to router
573 if normal server did not do it and did not find any results.
575 Affected file silcd/command.c.
577 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
579 * Moved the internal data from SilcClient context into its
580 own file, not accesible to application. Affected files
581 lib/silcclient/client.h and lib/silcclient/client_internal.h,
582 and other files in client library.
584 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
586 * Added doc/examples installation target in Makefile.am.pre.
589 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
591 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
592 commands the found client entry will be removed from the
593 cache, after notifying application about the error. Affected
594 file lib/silcclient/command_reply.c.
596 * Changed the /MSG to check for exact nickname user gave, and
597 not let `nick' match `nick@host' if it is only one found. Now,
598 user must type the exact nickname (like nick@host2) even if
599 there are no more than one same nicks found. This is to avoid
600 a possibility of sending nickname to wrong nickname since
601 `nick' could match `nick@host'. Affected file is
602 irssi/src/core/silc-servers.c.
604 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
606 * Do not print "you are now server operator" or similar when
607 giving /away command. Affected files are
608 irssi/src/silc/core/client_ops.c, silc-servers.h.
610 * Made the silc_server_command_pending_error_check to send
611 the same command reply payload it received back to the
612 original sender of the command. This way all arguments
613 that was received by the server will be received by the
614 client too. Affected file silcd/command.c.
616 * Added the silc_idcache_add to return the created cache entry
617 to a pointer. Affected file lib/silccore/silcidcache.[ch].
619 * Add global clients to expire if they are not on any channel.
620 This is because normal server will never know if they signoff
621 if they are not on any channel. The cache expiry will take
622 case of these entries. This is done by normal servers only.
623 The affected files are silcd/command_reply.c,
624 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
626 * If server receives invalid ID notification for WHOIS or
627 IDENTIFY and the ID exists in the lists, it is removed.
628 Affected file silcd/command_reply.c.
630 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
631 in client then client entry that it matches is searched and
632 the nickname is printed on the screen for user. Affected
633 file irssi/src/silc/core/client_ops.c.
635 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
637 * Use cache entry expire time in the LIST command reply to
638 purge old entries from the cache after the LIST command
639 reply has been received. This way we don't have non-existent
640 entries in the cache for too long. Affected file is
641 silcd/command_reply.c.
643 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
645 * If we are normal server, and we've not resolved client info
646 in WHOIS or IDENTIFY from router, and it is global client,
647 we'll check whether it is on some channel. If it is not
648 then we cannot be sure about its validity and will resolve it
649 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
650 file silcd/command.c.
652 * Search channel by name (if possible) rather than by ID
653 in IDENTIFY command's command reply. Affected file is
654 silcd/command_reply.c.
656 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
658 * Distribute to the channel passphrase in CMODE_CHANGE notify.
659 Updated specs and implemented it. Affected file silcd/command.c,
660 silcd/packet_send.c and silcd/packet_receive.c.
662 * Implemented the <founder auth> payload handling in the JOIN
663 command. If provided all conditions for channel joining
664 except requirement to provide correct passphrase can be
665 overrided by the channel founder. Updated the protocol specs.
666 Affected file silcd/command.c.
668 Added support for founder auth in JOIN command in client
669 library. Fixed the parsing of the JOIN command now to support
670 all options as they should be. The affected file is
671 lib/silcclient/command.c.
673 * Optimized the WHOIS and IDENTIFY commands to send the request
674 to router only if it includes nicknames or other names. If
675 they include only IDs then check the local cache first before
676 routing. Affected file is silcd/command.c.
678 * Added channels topic announcements. Affected file is
679 silcd/packet_receive.c and silcd/server.c.
681 * Fixed the silc_server_send_notify_topic_set to really destine
682 the packet to channel. Affected file silcd/packet_send.c.
684 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
685 library. Affected file lib/silcclient/client_notify.c.
687 * Added UMODE announcements. Affected file silcd/server.c.
689 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
691 * Memory leak fixes in:
693 lib/silcutil/silcsockconn.c
694 lib/silcske/silcske.c
697 lib/silccrypt/silcpkcs.c
698 lib/silccore/silccommand.c
699 lib/silccore/silcidcache.c
704 * ROBOdoc documented the lib/silcske/groups.h file and a
705 bit changed the interface for better.
707 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
709 * Update the client entry context in the ID cache after
710 nick change. Affected file lib/silcclient/command.c.
711 Fixes the CUMODE command when regaining founder privileges,
712 and a little WHOIS problem.
714 * Fixed silc_net_gethostbyname to correctly call the
715 inet_ntop. Affected file lib/silcutil/silcnet.c.
717 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
719 * Added IPv6 support checking to the configure.in.pre, added
720 also --enable-ipv6 option to override the check. Affected
721 file configure.in.pre.
723 * The silc_thread_create now calls the start function
724 directly if threads support is not compiled in. Removes
725 ugly #ifdef's from generic code. Affected files are
726 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
728 * Added silc_net_gethostby[name/addr]_async to asynchronously
729 resolve. Affected files are lib/silcutil/silcnet.[ch].
731 * Added support for rendering IPv6 based server, client and
732 channel IDs. Affected file lib/silcutil/silcutil.c.
734 * Added support for creating IPv6 based server IDs. Affected
735 file is silcd/serverid.c.
737 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
739 * Added silc_net_gethostby[addr/name] into the
740 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
741 routines. Added silc_net_is_ip[4/6]. Affected file is
742 lib/silcutil/unix/silcunixnet.c. All routines that take
743 address as argument now supports both IPv4 and IPv6 addresses.
745 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
747 * Fixed LIST command reply sending in server. Affected file
750 * Server now sends the kicker's client ID in the KICK notify
751 to the kicked client. Affected file silcd/command.c.
753 * The client library now parses the kickers client ID and
754 UI displays it. Affected files lib/silcclient/client_notify.c
755 and irssi/src/silc/core/silc-channels.c, module-formats.c.
757 * Made all payload parsing function prototypes consistent.
758 They all take now const unsigned char * and uint32 pair as
759 the payload data instead of SilcBuffer. Changes all around
760 the source tree. Other unsigned char* -> const unsigned char*
761 changes around the tree as well.
763 * Optimized SFTP client and server packet sending not to
764 allocate new buffer for each packet but to recycle the
765 first allocated buffer. Affected files are
766 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
768 * Optimized the SFTP client to use SilcList instead of
769 SilcDList for requests, because it is faster. Affected file
770 is lib/silcsftp/sftp_client.c.
772 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
773 into lib/silccore/silcid.[ch].
775 Renamed silcpayload.[ch] into silcargument.[ch].
777 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
779 * If client entry is deleted with active key agreement
780 session, abort the session.
782 The silc_client_abort_key_agreement now calls the completion
783 callback with new SILC_KEY_AGREEMENT_ABORTED status.
785 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
788 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
790 * Don't use __restrict in older GCC's. Affected file is
791 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
793 * silc_net_localhost now attempts to reverse lookup the
794 IP/hostname. Affected file lib/silcutil/silcnet.c.
796 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
797 command. It can be used to gain founder privileges at
798 the same time when joining the channel.
800 Defined that the SILC_NOTIFY_TYPE_KICKED send the
801 kicker's client ID as well. Updated protocol specs.
803 Defined that the server must send SILC_COMMAND_IDENTIFY
804 command reply with error status to client who sent
805 private message with invalid client ID.
807 Updated the protocol specification.
809 * Added silc_server_send_command_reply to send any
810 command reply. Affected file silcd/packet_send.[ch].
812 * Added silc_id_payload_encode_data to encode ID payload
813 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
815 * The server now send IDENTIFY command reply with error
816 status if client ID in private message is invalid. Affected
817 file silcd/packet_receive.c.
819 * Save the server key file with server's IP address in
820 the filename instead of hostname. The affected file is
821 irssi/src/silc/core/client_ops.c.
823 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
825 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
828 * Added libtool support for compiling shared objects in
829 lib/silcsim. Affected file configure.in.pre and
830 lib/silcsim/Makefile.am. Original patch by cras.
832 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
834 * Pid file configuration, and server's config file fixes
835 patch by toma. Updated CREDITS file.
837 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
839 * Fixed silc_client_channel_message to not try to decrypt
840 the message twice if it resolved the destination client
841 information. This could cause of dropping one channel
842 message. Affected file lib/silcclient/client_channel.c.
844 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
846 * Added silc_client_run_one into lib/silcclient/silcapi.h and
847 lib/silcclient/client.c. This function is used when the SILC
848 Client is run under some other scheduler, or event loop or
849 main loop. On GUI applications, for example this may be
850 desired to used to run the client under the GUI application's
851 main loop. Typically the GUI application would register an
852 idle task that calls this function multiple times in a second
853 to quickly process the SILC specific data.
855 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
857 * Fixed silc_server_drop() for dropping the supplementary
858 groups as well, this could cause a security hole on some
861 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
863 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
866 * Write PID file after dropping privileges. Added -F option
867 to run server on foreground. A patch by debolaz.
868 Affected files silcd/server.c, silcd/silcd.c.
870 * Fixed MOTD to return the MOTD file server name. Affected
871 file silcd/command.c.
873 * Added INFO command reply handling to the Irssi SILC Client.
874 Affected file irssi/src/silc/core/client_ops.c.
876 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
878 * Fixed the silc_idcache_list_* routines to really support
879 the dynamic list. Fixes a crash. Affected file is
880 lib/silccore/silcidcache.c.
882 * Fixed the LIST command reply to really call LIST command's
883 pending callbacks. Affected file silcd/command_reply.c.
885 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
887 * Update conn->local_entry->nickname after giving NICK
888 command. Affected file lib/silcclient/command.c.
890 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
892 * Added the [pid] option to the silcd configuration file
894 Affected files: serverconfig.[ch] and silcd.c
896 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
898 * Save fingerprint in WHOIS command reply in server.
899 Affected file silcd/command_reply.c.
901 * Fixed NICK commands pending callback registration.
902 Affected file lib/silcclient/command.c.
904 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
906 * Use ++server->cmd_ident when sending commands in server,
907 instead of random number. Affected file silcd/command.c.
909 * Fixed GETKEY command reply to call actually GETKEY pending
910 command callbacks. Affected file silcd/command_reply.c.
912 * A bit stricter check for nicknames. Check for same nickname
913 in NICK command also. Affected file silcd/command.c.
915 * Do not call INFO command everytime client ID changes, only
916 during first connecting. Affected file lib/silcclient/client.c.
918 * Set the new nickname only after successful command reply for
919 NICK command is returned by server. Affected file
920 lib/silcclient/command.c.
922 * Remove nicknames from nicklist during server_signoff notify.
923 Should fix /NAMES bit more. The affected file is
924 irssi/src/silc/core/silc-channels.c.
926 * Added `fingerprint' field to the SilcIDListData in the
927 silcd/idlist.h to hold the fingerprint of the client's
930 Send the fingerprint of the client's public key in WHOIS
933 Affected files silcd/command.c, and silcd/idlist.[ch].
935 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
936 create fingerprint from given data.
938 * Show the fingerprint of the client's public key in WHOIS.
939 Affected files irssi/src/module-formats.[ch] and
940 irssi/src/silc/core/client_ops.c.
942 * Format the multiple same nicknames also during JOIN and
943 NICK_CHANGE notifys. Affected file is
944 lib/silcclient/client_notify.c.
946 * Do not print error on screen for invalid private message
947 payload since it can come if someone is sending private
948 messages with wrong key. Affected file
949 lib/silccore/silcprivate.c.
951 * Fixed multiple concurrent /PING crash. Affected file
952 lib/silcclient/command.c.
954 * Changed the wrong ID encoding. All IP addresses must be
955 in MSB first order in encoded format. They were encoded
956 wrong and was in LSB format. Affected files are
957 silcd/serverid.c, lib/silcutil/silcutil.c.
959 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
961 * Call the `connect' client operation through the scheduler
962 in case of error. Affected file lib/silcclient/client.c.
964 * Call the `failure' client operation even if the error
965 occurred locally during a protocol. Affected file is
966 lib/silcclient/protocol.c.
968 * Added support of sending LIST command to router from normal
969 server. This way normal server can get list of all channels
970 in the network too. Fixed the channel list sending in the
971 server too. Affected files are silcd/command.c, and
972 silcd/command_reply.[ch].
974 * Added silc_server_update_channels_by_server and
975 silc_server_remove_channels_by_server. They are used during
976 disconnection of primary router and in backup router protocol.
977 Affected file silcd/server_util.[ch], silcd/server.c and
978 silcd/server_backup.c.
980 * Fixed channel adding to global list in IDENTIFY command
981 reply in server. Affected file silcd/command_reply.c.
983 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
985 * If the incoming packet type is REKEY or REKEY_DONE process
986 that packet always synchronously. Fixes yet another MAC
987 failed error on slow (dialup) connections. Affected file
988 lib/silcclient/client.c and silcd/server.c.
990 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
992 * Call check_version SKE callback for initiator too. Affected
993 file lib/silcske/silcske.c.
995 * Implemented fix for security hole found in the SKE that was
996 fixed in the specification few days back; the initiator's
997 public key is now added to the HASH value computation.
998 Added backwards support for the old way of doing it too, for
999 old clients and old servers. Affected file is
1000 lib/silcske/silcske.c.
1002 * Enabled mutual authentication by default in SKE. If initiator
1003 is not providing mutual authentication the responder will
1004 force it. This will provide the proof of posession of the
1005 private key for responder. The affected files are
1006 lib/silcclient/protocol.c and silcd/protocol.c.
1008 * Do not cache anymore the server's public key during SKE.
1009 We do mutual authentication so the proof of posession of
1010 private key is done, and if the server is authenticated in
1011 conn auth protocol with public key we must have the public
1012 key already. Affected file silcd/protocol.c.
1014 * Added new global debug variable: silc_debug_hexdump. If
1015 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1016 file lib/silcutil/silclog.[ch].
1018 * Fixed compilation warning due to char * -> const char *.
1019 Affected files lib/silcutil/silcnet.h, and
1020 lib/silccore/silcauth.[ch].
1022 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1024 * Fixed CMODE command when new channel key was created. If
1025 the creation failed the old key was removed. Next time giving
1026 same command would crash the server since the old key was
1027 freed already. Affected file silcd/command.c.
1029 * Fixed the silc_server_announce_get_channels to not crash
1030 on reconnect. Affected file silcd/server.c.
1032 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1034 * Added silc_log_set_debug_string function to set a regex
1035 string to match for debug output. Only the function names,
1036 or filenames matching the given debug string is actually
1037 printed. This way it is possible to filter out those debug
1038 strings that user is not interested in.
1040 Fixed a bug in silc_string_regexify.
1042 Affected files lib/silcutil/silclog.[ch], and
1043 lib/silcutil/unix/silcunixutil.c.
1045 * Changed the -d options in both server and Irssi SILC client
1046 to take the debug string as argument. Affected files
1047 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1049 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1051 * Added silc_hash_babbleprint to create a Bubble Babble
1052 Encoded fingerprint. The encoding is developed by Antti
1053 Huima (draft-huima-babble-01.txt), and it creates human
1054 readable strings out of binary data. Affected file
1055 lib/silccrypt/silchash.[ch].
1057 * Print the babble print now in addition of fingerprint as well
1058 in Irssi SILC client. Affected files are
1059 irssi/src/fe-common/silc/module-formats.[ch],
1060 irssi/src/fe-common/silc/core/client_ops.c.
1062 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1064 * Fixed a security problem found in SKE. The initiator's
1065 public key too is now added to the HASH hash value creation
1066 which is signed by the responder to create the SIGN value.
1067 This will prevent anyone in the middle to lie to the responder
1068 about the initiator's public key. If this is done now, the
1069 man in the middle will get caught. Updated the protocol
1072 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1074 * Better installation directory handling. Configure module
1075 paths and other paths automatically to example_silc* files
1076 in doc/. A patch by toma.
1078 * Fixed compiler warning from MPI library, and from SILC RNG.
1081 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1082 It can be configured with ./configure. A patch by toma.
1084 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1086 * Find correct make to use in prepare-clean. A patch by
1087 toma. Affected file prepare-clean.
1089 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1091 * Added irssi variables use_auto_addr, auto_bind_ip,
1092 auto_bind_port and auto_public_ip.
1094 * Changed the interface for silc_client_send_key_agreement
1095 in lib/silcclient/silcapi.h
1099 irssi/src/silc/core/silc-core.c
1101 lib/silcclient/silcapi.h
1102 irssi/src/silc/core/silc-channels.c
1103 lib/silcclient/client_keyagr.c
1106 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1108 * Added silc_pkcs_public_key_compare to compare two
1109 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1111 * Check that the client who set the founder mode on the
1112 channel is the same client that is giving the founder
1113 mode to itself. It is done by comparing the saved public
1114 key (it is saved even in the authentication is passphrase).
1115 Affected file silcd/command.c.

1122 * Process the DISCONNECT packet through scheduler in the
1123 client library. Affected file lib/silcclient/client.c.
1125 * Fixed the silc_client_packet_parse to not to increase
1126 the packet sequence number if the conn->sock and the
1127 current socket connection is not same. This can happen
1128 for example during key agreement when the conn includes
1129 multiple socket connections (listeners). Affected file
1130 lib/silcclient/client.c.
1132 * The sender of the file transfer request now provides also
1133 the pointer (listener) for the key exchange protocol. If
1134 the listener cannot be created then it sends empty key
1135 agreement and lets the receiver provide the listener.
1137 Added `local_ip' and `local_port' arguments to the
1138 silc_client_file_send. If they are provided they are used,
1139 if not then it will attempt to find local IP address, if
1140 not found or bind fails then the remote client will provide
1143 Affected files are lib/silcclient/client_ftp.c and
1144 lib/silcclient/silcapi.h.
1146 * Extended the FILE SEND command to support defining the
1147 local IP and port for key exchange listener. They are

1150 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1152 * Defined to WHOIS command reply the sending of fingerprint
1153 of the client's public key (if the proof of posession of the
1154 corresponding private key is verified by the server).
1155 Updated to the protocol specification.
1157 * Added support of receiving the client's public key's
1158 fingerprint in command reply in client library. Affected
1159 file is lib/silcclient/command_reply.c, and
1160 lib/silcclient/idlist.[ch].
1162 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1219 preserve the WHOWAS info for the client. Affected file
1220 silcd/server_util.c.
1222 * Fixed SERVER_SIGNOFF notify handling in the server. The
1223 server is now able to process incoming SERVER_SIGNOFF notify
1224 for a server that it doesn't even know about. It will remove
1225 the clients provided in the notify. Affected file
1226 silcd/packet_receive.c.
1228 * Check for partial packet in data queue after every packet that
1229 was found from the queue. Return and wait for more data if
1230 there is partial data in queue. Affected file is
1231 lib/silccore/silcpacket.c.
1233 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1248 irssi/src/fe-common/silc/module-formats.[ch].
1250 * Wrote a help file for FILE command.
1252 * Added silc_rng_global_get_byte_fast to get not-so-secure
1253 random data as fast as possible. Random data is read from
1254 /dev/urandom if available and from the SILC RNG if not
1255 available. It is used in padding generation. Affected file
1256 lib/silccrypt/silcrng.[ch].
1258 * All packets in client library are now processed synchronously.
1259 Optimized packet processing a lot. Affected file
1260 lib/silcclient/client.c.
1262 * All server connection packets are processing synchronously
1263 now in server, to optimize packet processing. Affected file
1266 * Include files are installed now only in Toolkit distribution
1267 if make install is given. Affected files: all Makefile.am's.
1269 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1271 * Assure that silc_client_notify_by_server_resolve does not
1272 resolve the client information multiple times. If it cannot
1273 be found by the first it cannot be found at all. Affected
1274 file lib/silcclient/client_notify.c.
1276 * Fixed WHOWAS command reply calling. Affected file
1277 lib/silcclient/command_reply.c.
1279 * Removed all references to silc_idlist_get_client from the
1280 Irssi SILC client since that call is internal call used by
1281 the library. The Irssi SILC client will use now client
1282 retrieval functions found in silcapi.h.
1284 * Fixed a bug in resolving nickname info before sending
1285 private message. It used freed memory. Affected file
1286 irssi/src/silc/core/silc-servers.c.

1307 * Added silc_net_localip to return local host's IP address.
1308 Affected file lib/silcutil/silcnet.[ch].
1310 * If key exchange or rekey protocol is active for a connection
1311 parse all packets syncronously since there might be packets
1312 in packet queue that we are not able to process without first
1313 processing packets before them. Affected file silcd/server,
1314 lib/silcclient/client.c.
1316 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1317 whether library should continue processing the packet.
1318 Affected file lib/silccore/silcpacket.h.

1365 is incomplete and is being resolved, it won't be resolved
1368 Make sure also that USERS command reply does not resolve
1369 twice information. Affected file is
1370 lib/silcclient/command_reply.c.
1372 Make sure that silc_client_get_clients_by_list does not
1373 resolve twice same information.
1375 * Check for valid client->id in the silc_server_free_client_data.
1376 Affected file silcd/server.c.
1378 * Fixed /GETKEY nick@server not to crash if the server entry

1391 * Call the silc_server_udpate_servers_by_server in the
1392 primary router that comes back online in the backup resuming
1393 protocol. Otherwise it routes packets wrong. Affected file
1394 silcd/server_util.[ch], silcd/server_backup.c.
1396 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1398 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1399 lib/silcutil/silcbuffmt.[ch].
1401 * Redefined the SILC packet header to include the padding
1402 length. Affected file lib/silccore/silcpacket.[ch].
1404 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1405 length for maximum padding up to 128 bytes). Affected
1406 file lib/silccore/silcpacket.h.
1408 * Removed all backwards support for old 0.5.x MAC thingies.
1409 The SILC packet header change makes it impossible to be
1410 backwards compatible.
1412 * Send the ENDING packet with timeout in the backup resuming
1413 protocol. This is to assure that all routers has connected
1414 to the primary router. Affected file silcd/server_backup.c.
1416 * Changed the RNG to take the first IV from random data. It
1417 used to take it from zero actually. Changed the RNG also
1418 to use /dev/urandom during session. /dev/random is used
1419 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1421 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1424 (the packet length) encrypted. Affected files aroung the
1425 code tree, lib/silccore/silcpacket.[ch]. Removed the
1426 SilcPacketCheckDecrypt callback. It is not needed anymore
1427 since the silc_packet_receive_process will determine now
1428 whether the packet is normal or special.

1439 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1441 * Allow backup router to announce servers. All servers
1442 announced by backup router are added to the global list
1443 automatically. Update hte server's socket to our primary
1444 router also when backup router announces a server.
1445 Affected file silcd/packet_receive.c.
1447 * Do not update the client->router in the function
1448 silc_server_udpate_clients_by_server if the client is on
1449 global list. We might fail to find any specific server
1450 for locally connected clients and local cell clients. They
1451 should still use the `from' and not `to' as client->router.
1452 This fixes backup router resuming protocol. Affected file
1453 silcd/server_util.c.
1455 * Decrease channel statistics count only if the channel
1456 deletion worked. Affected files are silcd/server.c and
1457 silcd/server_util.c.
1459 * Added silc_server_update_servers_by_server to update origin
1460 of all server entries. Used during backup router protocol.

1477 to the router it came from. Affected file is
1478 silcd/packet_send.c. Fixed memory leak too.
1480 * Announce informations for incoming router connection, but
1481 only after checking if it is replaced by backup router.
1482 Affected file silcd/packet_receive.c.
1484 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1487 router environment. Affected file silcd/server_backup.c.
1489 * Route packet only to one router in the function
1490 silc_server_packet_send_to_channel. Affected file is
1491 silcd/packet_send.c.
1493 * Fixed silc_server_send_notify_dest to set the broadcast
1494 flag. Fixed the silc_server_send_notify_topic to actually
1495 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1496 Affected file silcd/packet_send.c.
1498 * Changed the SFTP Filesystem interface. Changed the
1499 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1500 the filesystem operation function. The SilcSFTPFilesystem
1501 is now a context that is allocated by all filesystem allocation
1502 functions and it already includes the operations structure
1503 and filesystem specific context. It is given as argument
1504 now to the silc_sftp_server_start. This made the interface
1505 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1506 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1508 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1510 * Changed the backup router adding and getting interfaces
1511 in the server. The router that will be replaced by the
1512 specified backup router is now sent as argument. Affected

1565 send any data. Affected file lib/silcclient/client.c.
1567 * Implemented the backup router support when the primary router
1568 goes down. The servers and routers can now use the backup
1569 router as new primary router without loosing connectivity.

1573 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1574 in the server to indicate disabled entry. All data read
1575 from the connection will be ignored and no data is sent
1576 for entry that is disabled. Affected files are
1577 silcd/idlist.h, silcd/server.c.
1579 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1628 new packet type SILC_PACKET_FTP and defined File Transfer
1629 Payload. The mandatory file transfer protocol is SFTP
1630 (SSH File Transfer Protocol). Affected file in addition
1631 of the internet draft is lib/silccore/silcpacket.h.
1633 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1634 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1635 is used as part of backup router protocol when the primary
1636 router of the cell is back online and wishes to resume
1637 the position as primary router.
1639 * Redefined the MAC generation keys in the protocol. The
1640 same key is not used anymore in both direction. Both
1641 direction will now use different keys for sending and
1642 receiving. This fixes a potential security flaw. This
1643 change causes incompatibilities in the protocol.
1645 * Redefined also the MAC computation from the packet.
1646 An packet sequence number is now added to the MAC
1647 computation. This prevents possible replay attacks against
1648 the protocol. This change too causes incompatibilities
1651 Added `sequence' field to the SilcPacketContext to hold
1652 the current sequence number for the packet.
1654 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1656 * Added `created' field to the SilcIDListData in the file
1657 silcd/idlist.h to indicate the time when the entry was
1660 * Added `created' field to the SilcChannelEntry too. Affected
1661 file silcd/idlist.h.
1663 * Added `creation_time' aguments to all the announcement functions
1664 in the server. If it is provided then only the entries that
1665 was created after the provided time frame are actually
1666 announced. Affected file silcd/server.[ch].
1668 * The protocol says that the Channel ID's IP address must be
1669 based on the router's IP address. Added check for this in
1670 the silc_server_new_channel when processing incoming New Channel
1671 Payload. Affected file silcd/packet_receive.c.
1673 * Print out the correct version with --version in SILC client.
1674 Affected file irssi/src/silc/core/silc-core.c.
1676 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1678 * Fixed WHOWAS command to check for completnes of the client
1679 entry always, not just when the command is coming from client.
1680 Affected file silcd/command.c.
1682 * Added new function silc_server_packet_queue_purge to purge the
1683 outgoing data queue to the network. After the function returns
1684 it is guaranteed that the outgoing packet queue is empty.
1685 Affected file silcd/packet_send.[ch].
1687 * Purge the outgoing packet queue in the rekey protocol's final
1688 callback to assure that all rekey packets go to the network
1689 before quitting the protocol. Affected file silcd/server.c.
1691 * Added silc_client_packet_queue_parse as similar function as
1692 in server to the client library. The affected file is
1693 lib/silcclient/client.c.
1695 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1697 * Splitted silcd/server.c and created silcd/server_util.[ch]
1698 for utility functions.
1700 * Added new socket flag SILC_SF_DISABLED to indicate that the
1701 connection is open but nothing can be sent to or received from
1702 the connection. Affected file lib/silcutil/silsockconn.[ch].
1703 The checking for disabled socket is checked in the low level
1704 silc_socket_write and silc_socket_read functions.
1706 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1708 * Allow only nicknames and channel names that fits into the
1709 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1711 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1713 * When processing JOIN command reply in server check that if
1714 the channel exists in our global list we'll move it the local
1715 list. Affected file silcd/command_reply.c.
1717 * Fixed the check whether client is joined on the channel already
1718 in JOIN command. Affected file lib/silcclient/command.c.
1720 * Fixed the JOIN command reply to check whether the channel
1721 already exists. Affected file lib/silcclient/command_reply.c.
1723 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1725 * Added silc_ske_status_string to map the SKE error numbers
1726 to readable strings. The affected files are
1727 lib/silcske/silcske[_status].[ch].
1729 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1731 * Do not show the private channels on the WHOIS channel list
1732 as it is not allowed by the protocol. The affected file is
1735 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1737 * Assure that the packet length digged from the actual packet
1738 is something sensible in the silc_packet_decrypt_rest_special
1739 in lib/silccrypt/silcpacket.c.
1741 * Free and NULL the allocated pointer in silc_hmac_alloc if
1742 the HMAC allocation fails. The affected file is
1743 lib/silccrypt/silchmac.c.
1745 * Print the selected security properties to the log files in
1746 the server. Affected file silcd/protocol.c.
1748 * Add SKE's reference counter even if calling the completion
1749 callback manually. Otherwise it goes negative, although it
1750 does not cause any problems. The affected file is
1751 lib/silcske/silcske.c.
1753 * Remove the client entry with short timeout after giving the
1754 KILL command. Affected file lib/silcclient/command.c.
1756 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1757 case all found clients are already disconnected (WHOWAS would
1758 found them) in the server. Affected file silcd/command.c.
1760 * Update the last_receive (time of last data received) to be
1761 updated only when received private or channel message so that
1762 the idle time showed in WHOIS makes more sense.
1764 * Added boolean field `valid' in to the SilcClientEntry in the
1765 client library to indicate whether the entry is valid or not.
1766 This fixes the nickname change bug on channel when changing
1767 the nickname to be same than the old (like nick to Nick) the
1768 nickname formatter doesn't set the new nick anymore to Nick@host.
1769 Affected file lib/silcclient/idlist.[ch].
1771 * Now actually fixed the nickname changing on disconnection.
1772 Added new function silc_change_nick to the Irssi SILC Client.
1773 Affected file irssi/src/silc/core/client_ops.c,
1774 irssi/src/silc/core/silc-nicklist.[ch].
1776 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1778 * Check that the public key exists in the GETKEY command before
1779 trying to encode it. Affected file silcd/command.c.
1781 * Print some notifications on received public keys with GETKEY
1782 command in the Irssi SILC Client. Affected files are
1783 irssi/src/fe-common/silc/module-formats.[ch],
1784 irssi/src/silc/core/client_ops.c.
1786 * Use IDENTIFY command to resolve the server information in the
1787 GETKEY command instead of INFO command. Affected file
1788 lib/silcclient/command.c.
1790 * All command reply functions in the client library now calls
1791 the pending command reply callbacks even if an error has
1792 occurred. The server has done this a long time and now it was
1793 time to move the client library to this as well. Now all
1794 errors can be delivered back to the pending command reply
1795 callbacks if necessary. Affected files are
1796 lib/silcclient/command[_reply].[ch].
1798 * Change the nickname on disconnection back to the username
1799 because in reconnect the server will enforce it to it anyway.
1800 Affected file irssi/src/silc/core/silc-servers.c.
1802 * Fixed a config file parsing bug in the Irssi SILC client.
1803 Affected file irssi/src/silc/core/clientconfig.c.
1805 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1807 * When printing the channel mode on JOIN, verify that the
1808 channel key and channel's HMAC are valid. Affected file
1809 irssi/src/silc/core/client_ops.c.
1811 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1813 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1814 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1815 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1817 * Removed channel key rekey task deleting from the function
1818 silc_server_save_channel_key. Affected file silcd/server.c.
1819 Added explicit timeout task context instead that is used to
1820 delete the task if we are registering a new task before the
1821 new task has elapsed.
1823 * When channel key rekey occurs the client library now saves
1824 the old channel key for a short period of time (10 seconds) and
1825 is able to use it in case some is still sending channel
1826 messages encrypted with the old key after the rekey. Affected
1827 file lib/silcclient/[idlist.h|client_channel.c].
1829 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1831 * Added check to the silc_server_new_id_real to not accept
1832 new ID if it is the sender's own ID. Affected file is
1833 silcd/packet_receive.c.
1835 * Assure that we do not announce ourself or the one we've
1836 sending our announcements when we're router and are announcing
1837 servers to our primary router. Affected file silcd/server.c.
1839 * Fixed silc_server_command_identify_check_client to assemble
1840 correct WHOIS packet. It send corrupted WHOIS packet and
1841 caused problem with router to router connections. Affected
1842 file silcd/command.c.
1844 Fixed also silc_server_command_whois_check the same way
1845 as for the IDENTIFY command.
1847 * Added new SilcIDListStatus to the server in the SilcIDListData
1848 structure. The status now includes the current status of
1849 the entry (like registered, resolved etc.). Affected file
1850 silcd/idlist.[ch]. Defined a bunch of different status types
1851 as well. This replaced the old boolean registered field as well.
1853 Added resolve_cmd_ident field to the SilcClientEntry structure
1854 too so that if the entry is for example being resolved so
1855 another command may attach to the same pending command reply
1856 without requiring to resolve the same entry again. This concept
1857 should optimize the WHOIS and the IDENTIFY resolving under
1858 heavy load by taking away unnecessary resolving for entries
1859 that are being resolved already.
1861 Added support for adding multiple pending commands for one
1862 command idenfier. Affected file silcd/command[_reply].[ch].
1864 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1865 before deleting the data. Otherwise the hash table will have
1866 freed data in comparison functions. Affected file is
1867 silcd/command_reply.c.
1869 * Fixed silc_idlist_replace_client_id to add the new entry to
1870 the cache with NULL nickname. Otherwise there will be invalid
1871 memory as the nickname after the nickname is freed. Affected
1872 file silcd/packet_receive.c.
1874 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1875 saved into wrong slots because the previous number of entries
1876 was not taken into account. Affected file silcd/idlist.c.
1877 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1879 * If we are router and we receive JOIN notify to a channel that
1880 does not have any users then notified client is marked as the
1881 channel founder, as it is it. The affected file is
1882 silcd/packet_receive.c
1884 * Added to the extended hash table API's table_del_*ext functions
1885 the destructor as argument too, so that the caller can decide
1886 which destructor to use or whether to use destructor at all.
1887 Affected file lib/silcutil/silchashtable.[ch].
1889 * Fixed ID Cache purging. It actually deleted the entries from
1890 the hash table after the data was freed. The hash table ended
1891 up comparing freed memory. The affected file is
1892 lib/silccore/silcidcache.c.
1894 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1896 * Fixed Irssi SILC client's KILL command's HELP syntax.
1898 * The USERS command now resolves the detailed user information
1899 if the userinfo field is missing. Affected file is
1900 lib/silcclient/command_reply.c.
1902 * Do not print error in silc_file_read if the read file does
1903 not exist. Just silently return NULL. Affected file is
1904 lib/silcutil/silcutil.c.
1906 * Fixed the silc_log_output to not wine about NULL filename
1907 and to not create some bogus " " filename. Affected file is
1908 lib/silcutil/silclog.c.
1910 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1912 * Fixed various printing bugs on the user interface in the
1913 Irssi SILC Client. Minor changes that were forgotten from
1916 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1918 * Fixed the configure.in.pre and the compilation and distribution
1919 environment to support the new autoconf 2.52. That version is
1920 now required to compile the CVS trunk.
1922 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1924 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1925 to generally parse user@fqdn format strings. Affected file
1926 lib/silcutil/silcutil.c.
1928 * Added nickname_format and nickname_force_format fields to the
1929 SilcClientParams structure. The first one defines the format
1930 for the nicknames that the library will enforce if the receives
1931 multiple same nicknames. The second one is boolean value and
1932 can be used to force the library to always enforce the format
1933 to the nicknames regardles whether there are multiple nicknames
1934 or not. This configurable formatting was employed to flexibly
1935 support accessing multiple nicknames from the user interface.
1936 The userinterface can now set the nicknames to what ever format
1937 they prefer. Affected file lib/silcclient/silcapi.h.
1939 Added function silc_client_nickname_format to the file
1940 lib/silcclient/idlist.c. It performs the nickname formatting.
1942 Added new field `hostname´ to the SilcClientEntry context.
1943 It holds the hostname of the client. Affected file is
1944 lib/silcclient/idlist.h.
1946 * Irssi SILC Client sets the nicknames in nick@hostn format.
1947 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1948 irssi/src/silc/core/silc-core.c.
1950 The WHOIS printing now also shows both the real nickname and
1951 the formatted nickname so that user knows how to access the
1952 user if there are multiple same nicknames cached. Affected
1953 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1954 printing formatting too to take the hostname now as a separate
1955 argument. The Affected file is
1956 irssi/src/fe-common/silc/modules-formats.[ch].
1958 * Changed the silc_client_get_clients_local to accept the formatted
1959 nickname as argument. It accepts the real nickname too but the
1960 formatted nickname can be used to find the true entry from
1961 multiple entries. Affected file lib/silcclient/silcapi.h and
1962 lib/silcclient/idlist.c.
1964 * Added nickname_format_parse field to the SilcClientParams.
1965 It is a callback function provided by the application to parse
1966 the nickname out of the formatted nickname string. The library
1967 calls it to get the nickname from the formatted string. Since
1968 the application generally knows better the format of the nickname
1969 string it parses it instead of the library, even though library
1970 encodes the formatted string. If the callback function is not
1971 provided then the library will use the string as is. The
1972 affected file is lib/silcclient/silcapi.h.
1974 * All the nickname strings passed to the client library in
1975 commands are now expected to be formatted nickname strings.
1976 If the command does not support the formatted nickname string
1977 it will assume that the sent string is the actual nickname.
1978 Affected file lib/silcclient/command.c.
1980 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1982 * Added public key authentication support to OPER and SILCOPER
1983 commands in the client library. Affected file is
1984 lib/silcclient/command.c.
1986 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1988 * Changed the get_auth_methdod client operation to be asynchronous.
1989 It can be async if the application resolves the authentication
1990 method from the server during the negotiation. Added new
1991 SilcGetAuthMeth completion callback that the application will
1992 call after resolving the authentication method.
1994 Added function silc_client_request_authentication_method that
1995 the application can use to resolve the authentication method
1996 from the server. Added also SilcConnectionAuthRequest callback
1997 that the library will call after the server has replied. The
1998 application can call this function if it does not know the
1999 current authentication method.
2001 Affected files are lib/silcclient/client.c and
2002 lib/silcclient/silcapi.h.
2004 * The Irssi SILC client now automatically resolves the authentication
2005 method incase any configuration information is not present (and
2006 currently there never is). The affected file is
2007 irssi/src/silc/core/client_ops.c.
2009 * Fixed public key authentication from the client library.
2010 Affected file lib/silcclient/protocol.c. Changed also the
2011 protocol specification about the public key authentication in
2012 the connection authentication protocol. The actual data to be
2013 signed is now computed with a hash function before signing.
2015 * Fixed the public key authentication from the server as well.
2016 Affected file silcd/protocol.c.
2018 * Removed the mlock()'s from the memory allocation routines.
2019 Affected file lib/silcutil/silcmemory.c. The ./configure does
2020 not check anymore for the mlock(). Affected file is
2023 * Fixed USERS command in server to allow the execution of the
2024 command for private and secret channels if the client sending
2025 the command is on the channel. Affected file silcd/command.c.
2027 * Fixed silc_client_get_clients_local to return the clients
2028 count correctly. It could return wrong value. Affected file
2029 lib/silcclient/idlist.c.
2031 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2033 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2034 types. The assembler optimizations seemed not to like 64-bit
2035 data types. The assmebler optimizations thus are now enabled
2036 also for BSD systems as opposed to only enable them for Linux.
2038 * Do not check for threads at all on BSD systems. Affected
2039 file configure.in.pre.
2041 * Removed -n and -h options from the Irssi SILC Client since
2042 they are not used in silc.
2044 * Fixed the prime generation to assure that the first digit
2045 of the generated random number is not zero since our conversion
2046 routines does not like number strings that starts with zero
2047 digit. If zero digit is seen the random number is regenerated.
2048 This caused some corrupted RSA keys when the zero first digit
2049 was met. Affected file lib/silcmath/silcprimegen.c.
2051 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2053 * Fixed WIN32 configuration in the ./configure script.
2054 Fixed to include xti.h on environments that has it.
2055 Patches by Carsten Ilchmann and andrew.
2057 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2059 * Changed the silc_id_create_client_id to be collision
2060 resistant. It is now assured that there cannot be created
2061 two same client ID's. I suspect that some weird bugs in
2062 the server were actually caused by duplicate Client IDs.
2063 Affected file silcd/serverid.[ch]. A router receiving
2064 new ID now also assures and informs the sending server
2065 if the ID caused collision.
2067 * Changed the silc_id_create_channel_id to also assure that
2068 there are no collisions.
2070 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2072 * Statement about ignoring the Mutual Authentication flag when
2073 performing rekey with PFS was a bit misleading. It is ignored
2074 if it was set in the initial negotiation, it cannot be even
2075 set in the rekey. Fixed in the ke-auth draft. Started the
2076 new versions of the protocol drafts in the doc/.
2078 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2080 * Fixed a bug in silc_client_command_identify_save when saving
2081 new channel information. The channel name was no duplicated
2082 and caused crash on exit. Affected file is
2083 lib/silcclient/command_reply.c.
2085 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2087 * Fixed the getkey command handling in the server. Send just
2088 empty OK reply to the sender if the key could not be fetched
2089 (but everything else was ok, like the key just was not available).
2090 Changed the public key parameter to optional in the protocol
2091 specs so that empty OK reply can be sent. Affected file
2094 Added a message to Irssi SILC client to tell to user if the
2095 server did not return a public key.
2097 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2099 * Fixed a channel key regeneration bug. It registered new
2100 timeout tasks exponentially until all system resources were
2101 used. Affected file silcd/server.c.
2103 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2105 * Added the SILC Document generator to the scripts/silcdoc.
2106 It can be used to generate the Toolkit Reference Manual out
2107 of the source tree. Internally it will also use the RoboDoc
2108 generator now imported in util/robodoc.
2110 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2112 * Added couple of return's in rekey protocol if error orccurred
2113 during the protocol. The execution must be terminated.
2114 Affected file silcd/protocol.c. Also, terminate the protocol
2115 always with timeout.
2117 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2119 * The client's Client ID was created initally from the wrong
2120 nickname (it could have been in format nick@host) in the
2121 silc_server_new_client. Affected file silcd/packet_receive.c
2123 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2125 * Added some SILC_LOG_ERROR's to various error conditions
2126 if client could not be added to ID cache. Affected files
2127 silcd/packet_receive.c and silcd/server.c.
2129 * When client's sock->user_data is freed, NULL also the
2130 client->router and client->connection pointers. Added check
2131 for these pointers being NULL to various places around the
2132 code. Affected file silcd/server.c.
2134 * Added client->data.registered == TRUE checks to various
2135 places around the code to assure that unregistered client's
2136 are not handled when it is not allowed. Affected file
2139 * Added `bool registered' fields to all
2140 silc_idlist_[server|client]_get_* routines to indicate whether
2141 the fetched client needs to be registered or not. Affected
2142 file silcd/idlist.[ch].
2144 * Add your own entry as registered to the ID cache in the
2145 server. Affected file server.c.
2147 * Fixed a bug in silc_server_new_server. The SilcServer was
2148 set as the new server's context instead of SilcServerEntry.
2149 This naturally caused some weird bugs.
2151 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2153 * Do not delete the channel rekey task when adding it
2154 for in silc_server_create_channel_key.
2156 * Changed the silc_server_create_channel_key to return
2157 TRUE or FALSE to indicate the success of the channel key
2160 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2162 * Fixed MSVC++ project files and added missing files to

2167 * Do not add TCP_NODELAY flag if the operating system
2168 does not have it defined. Affected files are
2169 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2171 * Fixed buffer overflow from Irssi SILC Client. Affected
2172 file irssi/src/fe-common/core/themes.c.
2174 * Fixed double free in client library in the file
2175 lib/silcclient/client.c when disconnecting from server.
2177 * Applied double free patch from cras to Irssi SILC client.
2178 Affected files irssi/src/core/[modules/expandos].c
2180 * Fixed the disconnection handling to Irssi SILC Client.
2181 The application must call silc_client_close_connection
2182 in ops->connect client operation in case of failure of
2183 the connection. Affected file is
2184 irssi/src/silc/core/client_ops.c.
2186 * Do not set sock->protocol to NULL in the function
2187 silc_client_close_connection after executing the protocol's
2188 final callback since the sock might not be valid anymore.
2189 Affected file lib/silcclient/client.c.
2191 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2193 * Do not enable SILC_THREADS if the linking with libpthread
2194 did not happen. Affected file configure.in.pre.
2196 * Added notion to protocol specification that server must
2197 verify the sent authentication payload with CMODE when
2198 setting the channel founder key. Implemented it to the
2199 server. Affected file silcd/command.c.
2201 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2203 * Added _EXTRA_DIST SILC distribution variable to the
2204 distributions file. It is used to conditionally add extra
2205 files or directories to the specific distribution. Affected
2206 files ./prepare, Makefile.am.pre and distributions.

2211 * Added README.WIN32 for instructions to compile the Toolkit
2214 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2216 * Fixed a double free in disconnection in the server. Affected
2217 file is silcd/server.c.
2219 * Fixed the lib/silcske/groups.c to work now also with GMP
2220 MP library. The string conversion did not work when using
2221 specific base and the base is indicated in the string as well.
2223 * Created win32/ directory which now includes MSVC++ specific
2224 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2225 It will appear only in the toolkit distribution
2227 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2229 * Changed the key material distribution function in case when
2230 the hash output is too short. The data is now concatenated
2231 a bit differently than it used to. Made the change to the
2232 SKE protocol specification.
2234 * Added better GMP detection to configure.in.pre. A patch
2237 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2239 * Fixed a minor bug in SKE that might cause some problem on
2240 some platforms. Affected file lib/silcske/silcske.c.
2242 * Added the cookie checking for initiator in the SKE. It checks
2243 that the responder returns the sent cookie unmodified. The
2244 affected file is lib/silcske/silcske.c. Added new SKE
2245 error type INVALID_COOKIE that can be sent during the
2246 negotiation. Fixed some memory leaks as well.
2248 * Added the "invalid cookie" error message to Irssi SILC client's
2251 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2253 * Added `task_max' field to the SilcClientParams to indicate
2254 the maximum tasks the scheduler can handle. If set to zero,
2255 default values are used. Affected file lib/silcclient/silcapi.h.
2257 * Fixed memory leaks in silc_client_close_connection. Affected
2258 file lib/silcclient/client.c.
2260 * Added silc_client_del_client_entry to client library to free
2261 all memory of given client entry. Affected file is
2262 lib/silcclient/idlist.[ch].
2264 * Added new functions silc_client_del_channel and
2265 silc_client_del_server to delete channel and server entries.
2266 Affected file lib/silcclient/[silcapi.h/idlist.c].
2268 * Removed silc_client_del_client_by_id from silcapi.h.
2270 * Fixed the INFO command to return the server's own info
2271 correctly when querying by Server ID. Affected file is
2274 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2276 * Removed the non-blocking settings in WIN32 code in the
2277 silc_sock_[read/write] and added SleepEx instead. Affected
2278 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2279 of input data is now checked with FIONREAD and ioctlsocket.
2281 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2283 * Call silc_schedule_task_del_by_context in the
2284 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2285 Affected file lib/silccore/silcprotocol.c.
2287 * Call silc_protocol_cancel for active protocols in the
2288 silc_server_close_connection if the funtion
2289 silc_server_free_sock_user_data has not been called.
2290 Affected file silcd/server.c.
2292 * Generic tasks cannot be deleted using the del_by_fd
2293 task deleting function since generic tasks does not match
2294 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2296 * Added a notion to SILCOPER help file that the SILCOPER works
2297 only on router server, not on normal server.
2299 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2301 * Added for WIN32 support for the new scheduler as well.
2302 Affected file lib/silcutil/win32/silcwin32schedule.c.
2304 * Fixed the SHA1 implementation to work on various platforms.
2306 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2308 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2309 API. It is part of the scheduler now. Everything else is
2310 as previously but some functions has changed their names.
2311 Checkout the lib/silcutil/silcschedule.h for the interface.
2312 Updated all applications to use the new interface. Affected
2313 files are lib/silcutil/silcschedule.[ch].
2315 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2317 * Found a bug in the SKE implementation. The HASH value,
2318 specified by the protocol, was not computed correctly. The
2319 public key of the responder was not added to the computation
2320 even though it is mandatory. Affected file lib/silcske/silcske.c.
2321 This unfortunately causes incompatibilities with older
2322 clients and servers.
2324 * Added WIN32 specific network init and uninit functions:
2325 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2326 the Winsock2. Affected file lib/silcutil/silcnet.h and
2327 lib/silcutil/win32/silcwin32net.c.
2329 * Set the socket always to nonblocking mode on WIN32 after
2330 reading data or writing data. Affected file is
2331 lib/silcutil/win32/silcwin32sockconn.c.
2333 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2335 * Fixed various compilation problems under WIN32. Affected
2336 files lib/silcutil/win32/silcwin32thread.c and
2337 lib/silcutil/win32/silcwin32schedule.c.
2339 * Removed all _internal.h #includes from public header
2340 files. Internal headers must never be included from
2343 Removed also the lib/silcske/payload_internal.h file.
2345 * All include files that may be needed (public and some others
2346 included by the public headers) by application developers are
2347 now copied to the ./includes directory. It does not copy any
2348 internal headers. Affected file Makefile.defines.pre and all
2349 Makefile.am's under lib/ and subdirs.
2351 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2353 * Do not change the ~/.silc directory's permissions automatically.
2354 Affected file irssi/src/silc/core/clientutil.c.
2356 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2358 * Do not cancel the protocol in silc_server_close_connection
2359 it might cause recursion. Now cancelled in the function
2360 silc_server_free_sock_user_data. Affected file silcd/server.c.
2362 * Fixed the silc_server_remove_clients_by_server to regenerate
2363 the channel keys correctly finally. Added also new function
2364 silc_server_remove_clients_channels to actually do it.
2365 Affected file silcd/server.c.
2367 * Fixed the silc_server_new_channel to not crash by giving
2368 wrong router to the new channel. Affected file is
2369 silcd/packet_receive.c.
2371 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2373 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2374 which is given as argument to the silc_client_alloc now.
2375 It can be used to configure the client and set various parameters
2376 that affect the function of the client.
2378 * The USERS command in server did not check whether the channel
2379 is private or secret. Affected file silcd/command.c.
2381 * Added new argument to the USERS command in protocol specification.
2382 The USERS command now can take the channel name as argument
2383 as well. Added support for this in client and server and
2384 updated the protocol specs.
2386 * Completed the GETKEY command in client. It can be now used
2387 to fetch also servers public key not only some clients.
2388 Affected files lib/silcclient/command[_reply].c.
2390 * Added silc_client_get_server to return server entry by the
2391 server name. Affected files lib/silcclient/silcapi.h and
2394 * Redefined the IDENTIFY command in protocol specification to be
2395 more generic. It now can be used to query information about
2396 any entity in the SILC Network, including clients, servers and
2397 channels. The query may be based either the entity's name
2398 or the ID. Added support for this in both client and server.
2400 Affected files silcd/command.c and lib/silcclient/command.c
2401 and command_reply.c.
2403 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2404 the _from_client and _from_server functions. Affected file
2407 * Added silc_client_get_channel_by_id_resolve to the file
2408 lib/silcclient/silcapi.h to resolve channel information by
2409 its ID. Added also silc_client_get_channel_by_id that
2410 does not resolve it from the server.
2412 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2414 * Added SilcServerEntry context into the client library
2415 to represent one server. The INFO command now allocates
2416 these to save the resolved server info. For now on the
2417 client library will also keep information about servers,
2418 connected and resolved with INFO.
2420 The INFO command now allocates the SilcServerEntry context
2421 and saves the server info there. The COMMAND_REPLY in
2422 the INFO now returns the parameters to application in
2423 same order as defined in the protocol specification.
2425 The entries are cached in the client->server_cache.
2427 * The INFO command is now issued after received the Client ID
2428 from the server. Affected file lib/silcclient/client.c.
2430 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2431 to the application as the mode changer might be server.
2432 It is guaranteed that NULL is not returned anymore to the
2433 application. Affected file lib/silcclient/client_notify.c.
2435 The ID Type is now also passed to the application so that
2436 it can check whether the returned entry is SilcClientEntry
2439 Added new function silc_client_get_server_by_id to return
2440 the server entry by ID. Affected files are the
2441 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2443 * Do not create the channel in the Irssi SILC Client when issuing
2444 the JOIN command but when received the sucessful JOIN command
2445 reply. Otherwise the channel might get created even though we
2446 could not join it. The Affected file is
2447 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2449 * Fixed a channel joining bug in router. The router must also
2450 check the channel modes, invite and ban lists etc. when serving
2451 the JOIN command sent by normal server. Affected file is
2452 silcd/command.c. The router now resolves the client's
2453 information from the server who sent the JOIN command if it
2454 does not know it, and processes the JOIN command only after
2457 * Changed the SilcCommandCb to take new argument; void *context2.
2458 Affected file lib/silccore/silccommand.h
2460 The second argument in the command callbacks in the server now
2461 includes the SilcServerCommandReplyContext if the command was
2462 called as pending command callback from the command reply.
2463 Otherwise it is NULL. When called as pending the status of the
2464 command reply will be checked and if it was erronous the
2465 error will be sent to the original sender of the command.
2466 This way the client always receives the error messages even
2467 though the server was actually the one who received the error
2468 when it resent the command to router, for example. Affected
2469 files silcd/command[_reply].[ch].
2471 * Fixed sending WHOWAS command's error message to client if
2472 the requested client could not be found. It was missing.
2475 * Changed the CMODE and CUMODE commands reply arguments in the
2476 protocol specification. The Channel ID is now sent in both
2477 of the commands to identify the channel. Implemented this
2478 new feature to the client and server. Affected files
2479 lib/silcclient/command_reply.c and silcd/command.c.
2481 * Made better checks for invite and ban lists in the JOIN
2482 command in server. Affected file silcd/command.c.
2484 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2486 * The server now performs the incoming host IP/DNS lookup
2487 using the silc_socket_host_lookup and thus does not block
2488 the server anymore. Affected file silcd/server.c.
2490 * Completed the multi-thread support for SILC Scheduler in
2491 the lib/silcutil/silcschedule.c.
2493 * Fixed the configure.in.pre to detect the pthread correctly
2496 * Fixed a deadlock in silc_task_queue_wakeup in the file
2497 lib/silcutil/silctask.c.
2499 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2501 * Added new function silc_schedule_wakeup that is used in
2502 multi-threaded environment to wakeup the main thread's
2503 schduler. It needs to be used when a thread adds a new task
2504 or removes a task from task queues. After waking up, the
2505 scheduler will detect the task queue changes. If threads
2506 support is not compiled in this function has no effect.
2507 Implemented the wakeup mechanism to both Unix and WIN32
2508 systems. Affected files are lib/silcutil/silcschedule.[ch],
2509 lib/silcutil/unix/silcunixschedule.c and the
2510 lib/silcutil/win32/silcwin32schedule.c.
2512 * Added new function silc_task_queue_wakeup to wakeup the
2513 scheduler by the specified task queue. Affected file
2514 lib/silcutil/silctask.[ch].
2516 * The silc_socket_host_lookup_start now wakes up the scheduler
2517 after adding the timeout task. Affected file is
2518 lib/silcutil/silcsockconn.c.
2520 * The silc_socket_host_lookup is synchronous now if the threads
2521 support is not compiled in. However, the callback is still
2522 called asyncronously through the scheduler, anyway. Affected
2523 file lib/silcutil/silcsockconn.c.
2525 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2527 * Added new function silc_socket_host_lookup to perform
2528 asynchronous IP and FQDN lookups for the socket connection.
2529 Affected files lib/silcutil/silcsockconn.[ch].
2531 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2533 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2534 that may or may not compile the mutex support in.
2536 Changed the silc_mutex_alloc interface. It allocates the
2537 mutex now to the sent pointer and returns TRUE or FALSE.
2539 Affected file lib/silcutil/silcmutex.h.
2541 * Wrote the SILC Task Queue interface to support multi-threads.
2542 Affected file lib/silcutil/silctask.[ch].
2544 * Wrote the SILC Scheduler to support multi-threads. Affected
2545 file lib/silcutil/silcschedule.c.
2547 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2549 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2550 in lib/silcutil/win32/.
2552 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2554 * Defined SILC Mutex API and SILC Thread API and implemented
2555 them for Unix. Affected files are
2556 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2557 lib/silcutil/unix/silcunixmutex.c and
2558 lib/silcutil/unix/silcunixthread.c.
2560 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2562 * Fixed the silc_server_remove_clients_by_server's channel
2563 key re-generation. The hash table handling was incorrect
2564 and would not work with many channels. Affected file is
2567 * Fixed some memory leaks around the server code.
2569 * Rewrote the silc_server_get_users_on_channel to support IPv6
2570 based Client ID's. Affected file silcd/server.c.
2572 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2573 specification. However, a separate document must be written
2574 to define the detailed signing procedure and the payload
2575 associated with the flag. Defined the flag to the
2576 lib/silccore/silcchannel.h as well.
2578 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2580 * Changed the dynamic tables to static size tables in the
2581 lib/silccrypt/silchmac.c.
2583 * Removed GCC dependencies from the code. A patch by cras.
2585 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2587 * Do not show the error "Error receiving packet bla bla"
2588 in server if it really was not an error (-2 means that reading
2589 is pending). Affected file silcd/server.c.
2591 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2593 * Fixed a possible crash in silc_server_remove_clients_by_server
2594 in silcd/server.c. Fixed there also some memory leaks.
2596 * Fixed the silc_idlist_replace_client_id. It could replace
2597 wrong key in the hash table. Affected file silcd/idlist.c.
2599 * Do not check whether there are global users on the channel
2600 if the channel->global_users is FALSE. Affected functions
2601 silc_server_remove_from_one_channel and
2602 silc_server_remove_from_channels in silcd/server.c. Also,
2603 do not check if the removed client is local as we can be
2604 sure that global client was not removed from the channel
2605 and checking for global users is not needed.
2607 * The silc_server_remove_clients_by_server now re-generates
2608 the channel keys correctly for those channels that had
2609 clients removed from them. Affected file silcd/server.c.
2611 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2613 * Found the reason of random crashes in the server. We weren't
2614 ignoring the SIGPIPE signal (which can be sent in write())
2615 and it crashed the server. Affected file silcd/silcd.c.
2617 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2619 * Assure that sock->user_data is not NULL in the function
2620 silc_server_packet_send in silcd/packet_send.c.
2622 * Disconnect the remote connection if it could not be added
2623 to any ID lists in the server. The affected file is
2626 * Check in silc_server_packet_send[_real/dest] that the
2627 socket is not disconnecting and ignore the data if it is.
2628 Affected file silcd/packet_send.c.
2630 * Define inline to __inline on native WIN32 compilation.
2631 Affected file includes/silcwin32.h.
2633 * Added some explicit type casts for inline code since MSVC
2634 require them. Affected files lib/silcutil/silcbuffer.h,
2635 lib/trq/silcdlist.h and lib/trq/silclist.h.
2637 * Print warning in log files from now on if the packet
2638 decryption fails. Affected file silcd/server.c.
2640 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2642 * Changed the `say' client operation's interface to accept
2643 new `type' argument to indicate the type of the message sent
2644 by the library. The application may filter the library's
2645 messages according the type. The affected file is the
2646 lib/silcclient/silcapi.h.
2648 * Added two new functions to lib/silcclient/silcapi.h:
2649 silc_client_del_client and silc_client_del_client_by_id.
2650 Affected file lib/silcclient/idlist.c.
2652 * Moved the clientincludes.h from includes/ to silc/ and
2653 serverincludes.h from includes/ to silcd/.
2655 * The modes for the CMODE and CUMODE are now passed as
2656 uint32 for application with COMMAND_REPLY. The affected
2657 file is lib/silcclient/command_reply.c.
2659 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2661 * /WHOIS without arguments shows client's own information.
2662 Affected file lib/silcclient/command.c.
2664 * Changed PING to not accept any arguments. The specs
2665 says that client can ping only the connected server so
2666 requiring an argument is not needed. Affected file is
2667 lib/silcclient/command.c.
2669 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2671 * Fixed a fatal bug in private message sending and reception
2672 encryption and decryption when using private message keys.
2673 The implementation was incorrect and did not follow the
2674 specification. It causd that some of the message were
2675 lost since it did not use the sending and receiving keys
2676 as the protocol suggests. This has been fixed and will cause
2677 incompatibilities with older clients when sending private
2678 message encrypted with private message keys. Affected files
2679 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2680 and various other in Irssi SILC Client.
2682 Added `responder' boolean argument to the functions
2683 silc_client_add_private_message_key[_ske] to indicate when
2684 the key is added as responder or initiator of the key
2687 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2689 * Removed the silc_ske_check_version function and created
2690 a SilcSKECheckVersion callback. Added also a function
2691 silc_ske_set_callbacks that is now used to set all SKE
2692 callbacks. The callback functions are not given to
2693 the SKE functions anymore, but this function is used to
2696 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2698 * Added `silc_version' argument to the silc_client_alloc
2699 to define the version of the application for the library.
2700 The library will use the version string to compare it
2701 against the remote host's (usually a server) version
2702 string. Affected file lib/silcclient/silcapi.h
2704 * Added the KE protocol context to Key Agreement context
2705 in client library so that we can abort the SKE if it
2706 is in process when we get timeout. Affected file is
2707 lib/silcclient/client_keyagr.c.
2709 * Do not resolve the client ID forever if it returns in the
2710 first time that such client does not exist. This was done
2711 for example with private message. Affected file is
2712 lib/silcclient/client_prvmsg.c.
2714 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2716 * Do not add regex.h for WIN32. The affected file
2717 includes/silcincludes.h.
2719 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2720 not work yet 100%. It generates the DLL's automatically
2721 when compiling with --with-win32 under cygwin.
2723 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2725 * lib/contrib/regex.c is not compiled on WIN32.
2727 * Added silc_net_get_socket_opt function to the
2728 lib/silcutil/silcnet.h.
2730 * Added includes/silcwin32.h for WIN32 specific includes
2733 * Do not use ptime structure or any of the posix process
2734 functions on WIN32 in lib/silccrypt/silrng.c.
2736 * Added silc_gettimeofday to provide generic function
2737 for struct timeval on all platforms. Added the function
2738 to lib/silcutil/silcutil.h.
2740 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2742 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2743 library as they clearly belong there. As a plus side we
2744 can make the actual socket connection routines platform
2747 Added also new generic function silc_socket_read and
2748 silc_socket_write (that used to be silc_packet_[read/write].
2749 The implementation of these are platform specific.
2751 * Added WIN32 specific routines of silc_socket_[read/write]
2752 to lib/silcutil/win32/silcwin32sockconn.c.
2754 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2756 * Added preliminary support for native WIN32 compilation under
2757 cygwin (using the -mno-cygwin option for GCC) to the
2758 ./configure.in.pre. The --with-win32 now prepares the
2759 compilation for native WIN32.
2761 * Rewrote the SILC Scheduler interface in the file
2762 lib/silcutil/silcschedule.h. The scheduler is now context
2763 based and does not have anymore any global static scheduler.
2764 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2765 and created lib/silcutil/win32 directory for WIN32 based
2768 * Added Unix specific network routines to the
2769 lib/silcutil/unix/silcunixnet.c and the old
2770 lib/silcutil/silcnet.c includes now only generic routines.
2772 Added WIN32 specific network routines to the
2773 lib/silcutil/win32/silcwin32net.c.
2775 * Added Unix specific utility functions from the
2776 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2778 * Added WIN32 SILC Scheduler to the file
2779 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2782 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2784 * Do not handle JOIN notify in the server if the target client
2785 is not registered (idata->registered == FALSE). The affected
2786 file is silcd/packet_receive.c.
2788 * Update the nickrec->founder in event_cumode in the Irssi SILC
2789 client. Affected file irssi/src/silc/core/silc-channels.c.
2791 * Fixed the CUMODE_CHANGE notify handling in the server when
2792 server and router are announcing their clients on channels.
2793 Now the mode changes are saved and notified correctly. The
2794 affected file is /silcd/packet_receive.c.
2796 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2797 They really did not replace the cache entry in the ID Cache.
2798 Now they do that. Affected file silcd/idlist.c.
2800 * Fixed the KICK notify handling in the Irssi SILC client to
2801 update the channel records so that the kicked client does not
2802 appear to be on the channel. The affected file is
2803 irssi/src/silc/core/silc-channels.c.
2805 * Always update the conn->current_channel when executing command
2806 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2808 * Fixed the KILL notify handling in Irssi SILC client to remove
2809 the killed client on all channels.
2811 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2813 * Fixed the silc_parse_command_line to remove extra spaces
2814 from the start and end of the arguments. Affected file is
2815 lib/silcutil/silcutil.c.
2817 * Cancel and free any active protocol in the function
2818 silc_server_close_connection. Affected file silcd/server.c.
2820 * Cancel and free any active protocol in the function
2821 silc_client_close_connction. Affected file is
2822 lib/silcclient/client.c.
2824 * Do not execute the KILL command for clients that are in
2825 history (ie. they are not in the network). Affected file is
2828 * Fixed KILL notify handling, client does not crash anymore.
2829 Affected file irssi/src/silc/core/silc-channels.c.
2831 * Reduced the default packet buffer size from 2048 to 1024 in
2832 lib/silccore/silcpacket.c.
2834 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2835 counter to the SKE context that is incresed when the SKE library
2836 performs async operation outside the library. If the outside
2837 process frees the SKE context and FREED status will be set
2838 and the library will detect after the sync operation that the
2839 libary is freed. The affected files are
2840 lib/silcske/silcske[_status].[ch].
2842 * Resolve the client entry information in the function
2843 silc_client_channel_message to assure that NULL pointer is not
2844 passed as client entry to the application. */
2846 * Fixed the task timeout calculation to assure that there is
2847 never negative timeouts. The affected file is
2848 lib/silcutil/silcschedule.c.
2850 * Fixed the channel user mode notification sending in server.
2851 It was sent point-to-point to the router (or to server by router)
2852 but it needs to be destined to a channel. The routines now
2853 supports sending the channel user mode notifys to the channels
2854 when announcing clients and channels. Affected files are
2855 silcd/server.c and silcd/packet_receive.c.
2857 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2858 It did not actually replace the old channel entry in the cache.
2859 Affected file lib/silcclient/client_notify.c.
2861 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2863 * Fixed a possible crash in silc_packet_send_prepare. It now
2864 assures always that there is enough space in the buffer and
2865 at the tail area of the buffer (for MAC).
2867 Fixed the inbound buffer reallocation in silc_packet_read.
2868 It was old code and did not handle the reallocation correctly.
2871 The affected file is lib/silccore/silcpacket.c.
2873 * Fixed buffer overflow in silc_parse_nickname in the file
2874 lib/silcutil/silcutil.c.
2876 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2878 * make install generates new server keys only if there is not
2881 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2883 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2884 Added check that if the NOREPLY is set then we will not send
2885 the away message. This avoids infinite loop of away messages
2886 if both clients are away. The affected file is
2887 lib/silcclient/client_prvmsg.c.
2889 * Fixed client crash if /NICK was given without arguments.
2890 Affected file lib/silcclient/command.c.
2892 * Server does not send the invite list in INVITE command back
2893 to the client if the list was not altered. Added this notion
2894 to the protocol spec as well. Affected file silcd/command.c.
2896 Fixed possible crash in INVITE command by checking the
2897 value of silc_server_get_client_route command.
2899 * Fixed the INVITE notify type handling. The arguments are now
2900 taken in correct order and client does not crash. The affected
2901 file is irssi/src/silc/core/silc-channels.c.
2903 Removed the "Inviting xxx to channel" message from the
2904 client library away and let the application handle it.
2905 Affected file lib/silcclient/command.c. Added that message
2906 to Irssi SILC client's message formats.
2908 * Fixed CMODE command crash in client. It now checks the
2909 amount of arguments correctly and does not crash. The affected
2910 file is lib/silcclient/command.c.
2912 * Do not create new channel automatically in silc_channels_join
2913 but check whether the channel by that name already exists.
2914 Affected file irssi/silc/core/silc-channels.c.
2916 * Do not send the SERVER_SIGNOFF to router if the disconnected
2917 entity was the router. Affected file silcd/server.c.
2919 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2920 SILC client as it was missing from there.
2922 Added the handling of the KICK notify to the Irssi SILC client
2923 as it was missing. Added "you have been kicked" message to
2924 Irssi SILC client's message modules formats.
2926 Added the handing of the KILL notify to the Irssi SILC client
2927 as it was missing. Added the kill message module formats
2930 The affected file is irssi/src/silc/core/silc-channels.c.
2932 * The router did not save the channel mode the server announced.
2933 Affected file silcd/packet_receive.c.
2935 * Fixed a possible crash in INFO command in server. If the
2936 server did not provide the server info it crashed. Affected
2937 file silcd/command.c.
2939 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2941 * Fixed the GETKEY command in the server to check also the
2942 global list. Otherwise the GETKEY would not work correctly
2943 in normal SILC server. Affected file silcd/command.c.
2945 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2947 * Fixed GETKEY crash, it crashed if the command did not succseed.
2949 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2951 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2952 is now real and not just an macro interface to GMP.
2954 Removed the entire GMP from the source tree and imported new
2955 NSS MPI library instead. Reason for removing GMP is that it is
2956 extremely large and compiles extremely slow. The NSS MPI
2957 is only a few files and compiles in less than 10 seconds.
2958 The speed is also about the same as GMP. The MPI is imported
2959 to lib/silcmath/mpi.
2961 If the system has GMP installed we will still use the GMP.
2962 If it is not then the NSS MPI will be compiled.
2964 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2966 * Merged a long nickname (127 characters long) crash bugfix from
2967 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2969 * Merged a freed memory reference bugfix from Irssi CVS tree.
2970 Affected file irssi/src/core/commands.c.
2972 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2974 * Added the server's public key sving and verification to the
2975 server when performing the SKE. This was missing and the
2976 remote server's (or router's) public key was accepted without
2977 checking whether we have it previously or trust it at all.
2978 Affected file silcd/protocol.c.
2980 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2982 * Check in the silc_server_timeout_remote if protocol is active
2983 and make sure that the protocol's final callback is called so
2984 that all memory if freed. Affected file silcd/server.c.
2986 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2988 * silc_server_whois_send_reply crashed the server if the nickname
2989 was 127 characters long. Affected file silcd/command.c.
2991 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2993 * Added sanity check to the silc_server_new_client. If the hostname
2994 is provided inside username then check that the provided hostname
2995 really is the same as the resolved one. If the hostname was not
2996 resolved then check it from the public key. Affected file is
2997 silcd/packet_receive.c.
2999 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3000 if the server disconnected us and the connection is not valid
3001 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3003 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3004 the library to the lib/silcutil/silcutil.[ch].
3006 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3008 * Close log file after open. Affected file
3009 lib/silcutil/silclog.c.
3011 * Check whether sock == NULL in silc_client_send_packet and return
3012 if it is. Affected file lib/silcclient/silcclient.c.
3014 * Check rec->entry == NULL in the Irssi SILC Client before
3015 sending the channel message. Affecte file is
3016 irssi/src/silc/core/silc-servers.c.
3018 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3020 * Merged a splitted window bugfix from Irssi CVS tree. The
3021 affected file is irssi/src/fe-text/textbuffer-view.c.
3023 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3024 It did not print nickname.
3026 * Improved the distributions system a bit.
3028 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3030 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3031 irssi/src/fe-text/gui-window.c.
3033 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3034 to in-active server. The affected file is
3035 irssi/src/silc/core/client_ops.c.
3037 * Resolve the client in USERS command reply if the entry does
3038 not have username resolved. The affected file is
3039 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3040 command to WHOIS command to really resolve stuff. The USERS
3041 is not used any more in any critical section so WHOIS can
3042 be used even though it might be slower than IDENTIFY.
3044 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3047 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3049 * Changed the protocol API a bit more consistent in the
3050 lib/silccore/silcprotocol.[ch].
3052 * Changed the following headers to ROBODoc format:
3054 lib/silccore/silcpayload.h
3055 lib/silccore/silcprotocol.h
3056 lib/silccore/silcsockconn.h
3058 All core library headers are now formatted.
3060 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3062 * Fixed a bug in Irssi SILC client; do not show that you are
3063 server/router operator if you really are not. Affected file is
3064 irssi/src/silc/core/client_ops.c.
3066 * Renamed silc_command_free_payload to silc_command_payload_free.
3067 Affected file lib/silccore/silccommand.h
3069 * Added silcmath.h to include the prototoypes of various routines
3070 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3073 * Changed the following headers to ROBODoc format:
3075 lib/silccore/silcchannel.h
3076 lib/silccore/silccommand.h
3077 lib/silccore/silcid.h
3078 lib/silccore/silcidcache.h
3079 lib/silccore/silcmode.h
3080 lib/silccore/silcnotify.h
3081 lib/silccore/silcpacket.h
3082 lib/silcmath/silcmath.h
3084 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3086 * Added checking to the server code not to start the server if
3087 ciphers and stuff are not configured properly. Affected files
3088 silcd/serverconfig.[h] and silcd/server.c.
3090 * Changed the layout of the header files of the public interfaces
3091 in the SILC libraries. The new layout supports ROBODoc
3092 documentation tool (and some others) so that it is easy to create
3093 a library reference manual. All the other headers and source
3094 code must still follow the CodingStyle document. Also source
3095 code must not include these ROBODoc stuffs, only the headers.
3096 Furthermore, all public interface headers must now be named
3097 by using `silc' prefix, example: silcapi.h, silccipher.h.
3098 Some files were renamed due to this. All the other headers
3099 must not be used as public interfaces. I will update the
3100 CodingStyle document later. Changed following headers, so far:
3102 lib/silcclient/silcapi.h
3103 lib/silccore/silcauth.h
3104 lib/silccore/silcprivate.h
3105 lib/silccrypt/silcdh.h
3107 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3111 * Removed silc_client_packet_send_flush from the client library
3112 as it is not needed. Affected file lib/silcclient/client.[ch].
3114 * Added printing of message of unresolved authentication method
3115 to the Irssi SILC client. Added it to the module formats.
3116 Removed the same message from the client library.
3118 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Added new distribution feature, DISTLABEL. Every distribution
3121 can define own preprocessor label that can be used in the
3122 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3123 file distributions, acconfig.h.pre and prepare.
3125 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3127 * Added Makefile.defines_int to include the actual definitions
3128 for Makefile.defines.in. Tested the new distribution system,
3129 created distributions and tested installation.
3131 * Added AWAY message printing to the Irssi SILC client. Added
3132 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3134 * Added SCONNECT command to call the SILC's CONNECT command.
3135 Cannot use CONNECT directly since Irssi uses that internally.
3136 Affected file irssi/src/silc/core/silc-servers.c.
3138 Added ACTION local command. It is same as ME command but takes
3139 the channel as mandatory argument.
3141 Rewrote some of the Irssi's help files to suite for SILC
3144 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3146 * Added Makefile.defines[.in] that should for now on be included
3147 in all Makefile.am file in the source tree. That file includes
3148 all common compilation definitions for SILC source tree.
3150 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3152 * Minor changes to the ./prepare script to change the package
3153 name according the distribution name to the configure.in.
3155 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3157 * Created new distribution system. Added file `distributions'
3158 that defines all the distributions that can be created out of
3159 the SILC source tree. The ./prepare script now reads that
3160 file to determine how to prepare the distributions. The
3161 first argument to the ./prepare is the name of the distribution
3162 and second is the version of the distribution. If given
3163 without arguments it creates the default (toolkit) distribution
3164 with the default version (defined in ./prepare).
3166 All Makefile.am files that are subject to the distributions
3167 are now named as Makefile.am.pre. These are ./Makefile.am
3168 and lib/Makefile.am. Others may be changed later.
3170 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3172 * Added invite list, ban list, some key management and connection
3173 error message printing to module formats in the Irssi SILC client.
3175 * Added new silc_client_set_away_message to set the away message
3176 that is back to the person who sent private message. The
3177 affected file lib/silcclient/silcapi.h and the
3178 lib/silcclient/client_prvmsg.c.
3180 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3182 * Fixed the private message sending in the Irssi SILC client,
3183 added local command KEY to the Irssi SILC client.
3185 Added key management and key agreement message formats to the
3186 irssi/src/fe-common/silc/module-formats.[ch].
3188 Added USERS (alias WHO) printing, server/router operator
3189 indication and LIST command printing to the module formats.
3191 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3193 * Fixed channel joining notify handling, cumode notify handling
3194 from Irssi SILC client.
3196 * Added SILC specific module-formats to the Irssi SILC client so
3197 that SILC specific message hilighting, colors etc is possible.
3198 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3200 Added channel mode, channel user mode, actions, notices,
3201 whois and whowas printing to the the module-formats.c.
3203 * Fixed a bug in channel deletion in the server. The channel
3204 is not left to the cache even if the channel founder auth mode
3205 is set when there are no users anymore on the channel. Affected
3206 file silcd/server.c.
3208 * The silc_net_localhost now resolves the entire hostname including
3209 the domain name. Affected file lib/silcutil/silcnet.c.
3211 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3213 * Changed the ask_passphrase client operation to be ascynchronous.
3214 It has now a completion callback and a context that the
3215 application must call after it has got the passphrase from
3216 the user. Affected files lib/silcclient/silcapi.h,
3217 lib/silcclient/protocol.c, lib/silcclient/command.c and
3220 Added SilcAskPassphrase callback that the application calls
3221 to deliver the passphrase to the library.
3223 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3224 The public key verification and especially a certificate
3225 verification is asynchronous procedure.
3227 Added new SILC_SKE_STATUS_PENDING status to indicate the
3228 request is pending and a callback will be called to finalize
3231 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3232 indicate that remote end did not send its public key (or
3233 certificate), even though we require it. Added check for this
3234 condition in the SKE. This was a security bug, now fixed.
3236 Defined new SilcSKEVerifyCbCompletion callback that is called
3237 when the verification process is completed.
3239 The affected files lib/silcske/silcske_status.h and
3240 lib/silcske/silcske.[ch].
3242 * Changed the verify_public_key client operation to be async
3243 as well. Defined SilcVerifyPublicKey callback that is used to
3244 indicate the success of the public key verification process.
3246 Changed the server and client to use the new async client
3249 * Changed the Irssi SILC client's internal scheduler to be called
3250 twice as many times as it used to be. As a result the client
3251 should be a bit faster now. Affected file is
3252 irssi/src/silc/core/silc-core.c.
3254 * Added support to Irssi SILC client of asynchronous public key
3255 verification and passphrase inquiry. Affected file is
3256 irssi/src/silc/core/silc-core.c.
3258 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3260 * Do not say "You have left channel %s" in client library.
3261 Moved it to the application. Affected files are
3262 lib/silcclient/command.c and silc/client_ops.c.
3264 * Fixed silc_client_get_clients. Command context was not
3265 duplicated and was freed memory in the callback. Affected
3266 file lib/silcclient/idlist.c.
3268 * Do not say "you are now talking..." on JOIN command in the
3269 client library. The appliation must handle it.
3271 * Do not say ".. changed topic to" in command reply in the
3272 client libary. The application must handle it.
3274 * Fixed TOPIC command sending in the client library.
3276 * Fixed a memory leak in silc_client_command_free in the file
3277 lib/silcclient/command.c.
3279 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3281 * Imported a modified version of Irssi client to the source tree.
3282 The Irssi will be used to create a new client called
3283 Irssi SILC. Imported to irssi/.
3285 Added silc_core_init_finish function to the Irssi. Affected
3286 file irssi/configure.in.
3288 A lot changes in the Makefile.ams around the irssi tree.
3290 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Do not rehash if the new size is same as the old size of the
3293 hash table, in the silc_hash_table_rehash*. The affected file
3294 lib/silcutil/silchashtable.c.
3296 * Replaced hash_table_del_by_context calls from the server
3297 (when channel->user_list and client->channels) to the
3298 hash_table_del as it is sufficient and faster.
3300 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Added silc_hash_table_list, silc_hash_table_get and the
3303 SilcHashTableList structure to provide an alternative way to
3304 traverse the hash table. The affected files are
3305 lib/silcutil/silchashtable.[ch].
3307 * Changed the server's idlist routines to use the hash table
3308 routines to optimize the code.
3310 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3312 * Replaced the client entry's `channel' list and channel entry's
3313 `user_list' list to hash tables for optimized lookup. Changed
3314 the code to use the hash table interface around the code.
3315 Affected file lib/silcd/idlist.[ch].
3317 * Added `auto_rehash' boolean argument to the function
3318 silc_hash_table_alloc to indicate whether the hash table should
3319 auto-rehash when it thinks is appropriate time. It will
3320 increase the hash table size if the there is twice as much
3321 entries in the table than the size of the table, and will
3322 decrease the size if there are twice as less entries than
3323 the size of the table.
3325 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3327 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3329 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3331 * silc_idcache_purge_by_context deletes the entry now by context
3332 as it is supposed to do. Affected file lib/silccore/idcache.c.
3334 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3335 client is not anymore valid (WHOWAS givens the info) and not
3336 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3338 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3340 * Removed the `data' and `data_len' arguments from the ID Cache
3341 interfaces and added `name' argument. ID Cache does not handle
3342 anymore the binary data only a names associated with given ID.
3344 * When hashing a Client ID with silc_hash_id the entire ID is
3345 not hashed anymore, instead only the hash of the Client ID is
3346 hashed. This way we can access the Client ID from the cache
3347 with Client ID but with the hash of the ID (which is a hash of
3348 the nickname) as well without any difference in performance.
3350 Added also silc_idcache_find_by_id_one_ext to do one on one
3351 searching when we have the actual ID. Added also function
3352 silc_hash_client_id_compare. The affected files are
3353 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3355 * When hashing the name associated with a ID it is always done
3356 in lowercase. This way we can access the cache without worrying
3357 about case-sensitivity, even though, for example nicknames are
3360 * Fixed a bug in server with channel message sending. It put
3361 wrong ID type as destination ID. The affected file
3362 silcd/packet_send.c.
3364 * silc_idcache_del_by_context now deletes from all hash tables
3365 by context. Affected file lib/silccore/idcache.c.
3367 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3369 * Changed the client library to use the new ID Cache interface.
3370 Changes around the source tree.
3372 * Added silc_hash_table_rehash_ext to rehash with specific
3373 hash function. Affected file lib/silcutil/silchashtable.[ch].
3375 * Added silc_hash_string_compare to compare two strings in the
3376 hash table. Affected file lib/silcutil/silcutil.[ch].
3378 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Added new function silc_idcache_del_by_context into the
3381 lib/silccore/idcache.[ch].
3383 * Changed the server's ID list routines to use the new ID Cache
3384 interface. Changes around the source tree.
3386 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3388 * Added silc_hash_table_del[_by_context]_ext functions in to the
3389 lib/silcutil/silchashtable.[ch].
3391 Removed silc_hash_table_find_all* routines and added new
3392 silc_hash_table_find_foreach to replace them.
3394 Added silc_hash_table_replace_ext function as extended
3395 replacing function. Separated the simple hash table interface
3396 from the extended hash table interface in the file
3397 lib/silcutil/silchashtable.h.
3399 * Fixed minor bugs and changed it to use some of the new
3400 hash table functions in lib/silccore/idcache.c
3402 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3404 * Added new function silc_hash_table_find_all to return all keys
3405 in the hash table by the specified key. As the hash table is
3406 collision resistant it also makes it possible to have several
3407 duplicate keys in the hash table. This function may be used to
3408 find all of the keys from the hash.
3410 Added user_context arguments to the SilcHashFunction,
3411 SilcHashCompare and SilcHashDestructor to deliver user specified
3414 Added new fuctions silc_hash_table_find[_all]_ext to do
3415 extended lookup with specified hash and compare functions and
3416 specified user contexts.
3418 Added new function silc_hash_table_add_ext to add the key
3419 with specified hash function and user context.
3421 Added new function silc_hash_table_foreach to traverse all
3422 entrys in the hash table. Added SilcHashForeach callback
3425 Added new function silc_hash_table_del_by_context to delete
3426 the entry only if the context associated with the key matches.
3428 Affected files are lib/silcutil/silchashtable.[ch].
3430 * Removed silc_hash_[server/client/channel]_id and added just
3431 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3432 silc_hash_id_compare to compare two ID's using as the hash table
3433 comparison function. Added also silc_hash_data to hash
3434 binary data and silc_hash_data_compare to compare it.
3436 * Removed silc_idlist_find_client_by_hash as it is not needed
3437 anymore. Affected file silcd/idlist.[ch].
3439 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3440 to use internally the SilcHashTable. The new ID Cache is a lot
3441 faster than the old one. Some of the ID Cache interface was also
3442 rewritten and obsolete and stupid functions were removed.
3444 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3446 * Added entry_count field to the SilcHashTable to keep the number
3447 of the entries in the table. Implemented the function
3448 silc_hash_table_rehash. Added new function
3449 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3451 Fixed a minor bug in silc_hash_table_free.
3453 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3454 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3455 into the lib/silcutil/silcutil.[ch].
3457 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3459 * Implemented a collision resistant hash table into the
3460 lib/silcutil/silchashtable[ch]. See the header and the source
3461 for the SilcHashTable API.
3463 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3465 * Merged dotconf version 1.0.2 into lib/dotconf.
3467 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3469 * Do not compile anything in lib/silcsim/* if the SIM support
3470 is not enabled. The tree should now compile without problems
3473 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3475 * Compiled the SILC under cygwin. Compiled and tested briefly
3476 without problems. More tests needed. The SIMs didn't compile
3479 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3481 * Fixed possible crash in silc_get_username in the
3482 lib/silcutil/silcutil.c.
3484 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3486 * Fixed a va_arg in silc/client_ops.c.
3488 * Oops, RC5 routines were named AES and caused some problems
3489 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3491 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3493 * Added new SilcIDIP structure into the lib/silccore/id.h and
3494 replaced the old `ip' fields from all SILC ID's to that type.
3495 This is a step towards IPv6 support.
3497 The silc_id_get_len takes now the ID as an extra argument.
3498 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3499 both IPv4 and IPv6 based ID's.
3501 The affected files are lib/silccore/id.[ch] and other files
3502 around the tree using these routines.
3504 * Removed the ID length arguments in server from various
3505 silc_server_send_notify_* routines -> they are not needed
3508 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Fixed memory leak in silc_encode_pem_file in the file
3511 lib/silcutil/silcutil.c.
3513 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3515 * Check minor version as well in the SKE. Affected files are
3516 silcd/protocol.c and lib/silcclient/protocol.c.
3518 * Added --identifier option to the server so that an identifier
3519 can be when creating the public key for the server. Affected
3520 file is silcd/silcd.c.
3522 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3523 lib/silccrypt/silcpkcs.c.
3525 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3527 * Register default ciphers and stuff when using -C option with
3528 the server. Affected file sildc/silcd.c.
3530 * Put back the servers public key filename format, it is better
3531 than the new one. For now, the client keys are saved with the
3532 new filename format. The affected file silc/client_ops.c.
3534 * Implemented the Cipher API for the rest of the ciphers that
3535 did not implement it or implemented it the wrong way.
3537 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3539 * Register default ciphers and stuff when using the -S option
3540 in the client. Affected file silc/silc.c. Same also when
3541 creating new key pair with -C option.
3543 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3545 * Fixed the silc_verify_public_key client operation function to
3546 save the public keys differently. The fingerprint is now
3547 used as filename and not the hostname. This way also the
3548 client keys are saved uniquely and not with hostnames. The
3549 affected file is silc/client_ops.c.
3551 * Trimmed the silc_hash_fingerprint function to remove extra
3552 whitespaces from the end of the fingerprint. The affected
3553 file is lib/silccrypt/silchash.c.
3557 * Added silc_cipher_register_default function to register all
3558 default ciphers. It can be used when configuration files
3559 does not exist and the application does not want any specific
3560 ciphers in any specific order.
3562 The SilcDList is now used as silc_cipher_list dynamically
3563 allocated cipher list. Removed the static list all together
3564 and now all ciphers must be allocated to the dynamic list.
3565 The silc_cipher_alloc routine was changed to check only the
3568 All silc_cipher_* routines that used to return int returns
3571 The affected files lib/silccrypt/silccrypt.[ch].
3573 * The same thing was done to silc_hash_* as for silc_cipher_*
3574 routines. Affected files lib/silccrypt/silchash.[ch].
3576 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3577 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3578 Added also silc_pkcs_[un]register[_default] functions.
3579 Removed the data_context from the PKCS API.
3581 * Added silc_hmac_register_default function to register default
3582 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3583 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3584 to unregister all hmacs at once.
3586 * Register the default ciphers, hash functions, PKCSs and HMACs
3587 if client's configuration file does not exist. The affected
3590 * The client did not load the hash functions from the SIM
3591 modules at all. Added support for this. Affected file is
3592 silc/clientconfig.c.
3594 * When decoding public key with silc_pkcs_public_key_decode, check
3595 the supported algorithm only if PKCS are registered. Affected
3596 file lib/silccrypt/silcpkcs.c. The same was done with the
3597 silc_pkcs_private_key_decode.
3599 * Fixed the SILC List routines to keep the list always in order.
3600 It used to change the list's order when traversing the list but
3601 not it preserves the order. Affected file lib/trq/silclist.h.
3603 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * Added the client library to use the SilcSocketConnection's
3606 reference counter (by silc_socket_dup) to prevent the bug that
3607 the socket object may be freed underneath async operation.
3609 * The name resolv library checking fixes in the configure.in.pre.
3612 * Created new version of the protocol drafts for future
3613 development. The -03 drafts are the ones that will be changed
3614 in the trunk now and the -02 will remain as they are.
3616 * Send list of CUMODE notifys to the router when announcing
3617 the channel users to the router. Affected file silcd/server.c.
3618 If the router receiving channel founder CUMODE for a channel
3619 that already has channel founder it will send CUMODE notify
3620 to the sender to remove the channel founder rights from the
3621 announced client. Affected file silcd/packet_receive.c.
3623 * The CUMODE notify may now use Server ID as well as the entity
3624 who changes the mode. Updated protocool specs.
3626 * Updated INSTALL and README files.
3628 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * New web pages in the http://silc.pspt.fi. The pages was
3635 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3637 * Implemented the [DenyConnectin] config section in the server.
3638 Added silc_server_config_denied_conn to check whether incoming
3639 connection is denied. Affected file silcd/serverconfig.[ch].
3641 * Do not check the ports when checking the incoming configuration
3642 data if the port is 0, meaning any. Affected file is
3643 silcd/serverconfig.c.
3645 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3647 * Fixed buffer overflow in silc_string_compare in the file
3648 lib/silcutil/silcutil.c.
3650 * Fixed double free in silc_server_command_leave in the file
3653 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3655 * Fixed the version checking in the server. Affected file is
3658 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3660 * Fixed the configuration data fetching when accepting new
3661 connections in the server. Affected file silcd/server.c.
3663 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3665 * Added `sender_entry' argument to the function
3666 silc_server_packet_relay_to_channel so that we can check
3667 whether some destination actually belongs to the same route
3668 the sender belongs (ie, we must not resend the packet to the
3669 sender). Affected file silcd/packet_send.[ch].
3671 * Added `servername' field to the SilcClientEntry in the server
3672 to hold the name of the server where client is from. Affected
3673 file is silcd/idlist.h.
3675 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3677 * Moved the channel message encrypting in the router betwen
3678 router connections from silc_server_channel_message to the
3679 silc_server_packet_relay_to_channel since we want to check
3680 whether we have anybody channel before encrypting anything.
3681 Affected files silcd/packet_[receive/send].c.
3683 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3685 * Fixed the [AdminConnection] server config section to support
3686 multiple entries. Affected file silcd/serverconfig.c.
3688 * Added support into the server to check the validity of the
3689 incoming connection before executing any KE or authentication
3692 * The connection configuration is now saved to the KE and
3693 connection auth protocol contexts and not fetched anymore in
3694 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3696 * The local hosts listenning address and port is also resolved
3697 now when starting the server. We want to have the socket object
3698 to include the real address and port for the listener. Added
3699 new function silc_net_check_local_by_sock into the files
3700 lib/silcutil/silcnet.[ch].
3702 * Fixed a broadcast bug in server -> do not broadcast if we
3705 * Fixed a routing bug. Do not route broadcast packets ever.
3706 Broadcast packets must be processed always and not routed since
3707 they may be destined to some other host than yourself and thus
3708 would get routed without no good reason. Affected file is
3711 * Added function silc_server_config_is_primary_route to check
3712 whether primary router connection has been configured (a router
3713 configuration that we are initiating). If there is not, we
3714 will assume that there is only two routers in the SILC network
3715 and we will use the incoming router connection as our primary
3716 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3718 * Changed the order of the broadcasting. Broadcast _after_ the
3719 packet has been processed not before. Affected file is
3722 * Fixed a [ClientConnection] parsing bug. The port was never
3723 parsed correctly thus resulting to port 0. Affected file
3724 silcd/serverconfig.c.
3726 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3727 argument and did not set the broadcast packet flag. Affected
3728 file silcd/packet_send.c. Fixed same bug in the function
3729 silc_server_send_notify as well.
3731 * If we receive NEW_ID packet for our own ID in the server, ignore
3734 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3738 * Removed the nickname from the Private Message Payload.
3739 Updated the code and the protocol specs.
3741 * Updated protocol specs for submitting to the IETF.
3743 * Tweaked the Random Number Generator a bit. Affected file
3744 lib/silccrypt/silcrng.c. Exported a new function
3745 silc_rng_[global]_add_noise which can be used to add more
3748 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3750 * Do not parse packets with different timeout when protocol
3751 is active -> may cause problem with rekey. Affected file
3754 * When server receives signoff notify it must not create
3755 new channel key if the client is on any channels since the
3756 sender of the signoff notify will create it.
3758 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3760 * Added printing of error messages during SKE protocol from the
3761 failure packet sent by server during SKE. Affected file
3764 * Removed the client's failure_callback handling with timeout
3765 and handle it immediately when received.
3767 * The SKE library returned wrong type in SUCCESS and FAILURE
3768 packets. They must be 32 bit MSB not 16 bit MSB.
3770 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3772 * Ok, rewrote the logic of the re-key and now it seems to work.
3773 I tested it on high traffic with frequent re-keys without
3774 problems. Added hmac_receive (and renamed hmac to hmac_send)
3775 in SilcClientConnection in lib/silcclient/client.h and
3776 in SilcIDListData in silcd/idlist.h. Also, removed the
3777 SilcPacketParserContext's cipher and hmac fields as they are
3778 not needed anymore and actually caused some problems when
3779 the ciphers and hmac's changed underneath the packet parser.
3781 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3783 * If re-key protocol is active then process the incoming packets
3784 synchronously since we must assure that icoming packets encrypted
3785 with the old key is processed before the new keys is set to
3786 use. This is true other packets than for REKEY packets.
3787 Affected file silcd/server.c. The same was done to client library
3788 as well, affected file lib/silcclient/client.c.
3790 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Fixed bug in client and server to accept the force send if
3793 the packet is send from silc_[server/client]_packet_process
3794 function. Otherwise the packets are never delivered, oops.
3796 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3798 * Disable force sending of packets when REKEY protocol is active.
3799 We must assure that no packet is sent directly when rekey is
3800 performed. All packets must be sent through packet queue.
3801 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3802 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3803 function is silc_[server/client]_packet_send_real to check
3806 * Replaced the SIM paths from example config files to
3807 /usr/local/modules. Also, make install creates now
3808 /usr/local/silc/logs directory to hold all the SILC server
3811 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3813 * Made the configure.in.pre work on Solaris. Patch by salo.
3815 * Made all ciphers compatible with non-x86 machines. Defined
3816 CBC mode macros into lib/silccrypt/ciphers_def.h.
3818 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3820 * Fixed the make install.
3822 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3824 * When MAC computation fails the silc_packet_decrypt returned 0
3825 even though it was supposed to return -1. Fixed this. The
3826 affected file is lib/silccore/silcpacket.c.
3828 * Do not replace the config files in /etc/silc (in make install)
3829 if they already exist. Affected file ./Makefile.am.
3831 * Do not send re-key packets immediately but through packet queue.
3832 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3834 * Changed silc_net_check_host_by_sock to return FALSE if the
3835 IP/DNS could not be resolved. Though, it returns the IP address
3836 now even if it could not resolve it (but returns also FALSE).
3837 Affected file lib/silcutil/silcnet.[ch].
3839 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3841 * Added silc_pkcs_decode_identifier to decode the public key's
3842 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3843 Added also silc_pkcs_free_identifier. Added also new context
3844 SilcPublicKeyIdentifier.
3846 * Added -S option to the silc client. It is used to dump the
3847 contents of the specified public key file.
3849 * Changed the PKCS api to return the public key length when
3850 setting the public key.
3852 * Fixed a fatal bug in the public and private key file loading.
3853 Affected file lib/silccrypt/silcpkcs.c.
3855 * Execute the packet parsing for client with zero (0) timeout
3856 if the protocol is active. Affected file silcd/server.c.
3858 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3860 * Made the key generation options to the silcd program. Added
3861 -C option, equivalent to client's option.
3863 * Added new [ServerKeys] config section to the server. It
3864 configures the server's public and private key.
3866 * Defined generic Public Key Payload into the protocol
3867 specification to send specific type of public keys and
3870 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3871 public key or certificate.
3873 * Implemented the GETKEY command to the server and to the
3874 client library and on user interface.
3876 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3878 * Made preliminary `make install' work.
3880 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * Added SilcServerRekey context into silcd/idlist.h.
3884 * Added the PFS support as defined in the specification to the
3885 SKE protocol. Affected files lib/silcske/*.c.
3887 * Added `ske_group' field to the SilcServerRekey context to hold
3888 the number of the SKE group that is used with PFS in re-key.
3889 Affected file silcd/idlist.h.
3891 * Added PFS re-key support to the server. Affected file is
3894 * Added silc_protocol_cancel to cancel execution of the next
3895 state of the protocol. Affected file is
3896 lib/silccore/silcprotocol.[ch].
3898 * Added the re-key support with and without PFS to the client
3899 library. Re-key is performed once in an hour, by default.
3901 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3902 Added silc_client_rekey_callback and silc_client_rekey_final.
3903 Affected files are lib/silcclient/protocol.[ch] and
3904 lib/silcclient/client.[ch].
3906 * Removed the `hmac_key' and `hmac_key_len' fields from the
3907 SilcClientConnection structure; not needed. Affected file is
3908 lib/silcclient/client.h.
3912 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3914 * Do not ask whether user wants to use the negotiated private key
3915 for private messages, just use it. Affected file is
3916 silc/local_command.c.
3918 * Added `send_enc_key' and `enc_key_len' fields to the
3919 SilcIDListData structure since they are needed in the re-key
3920 phase. Affected file is silcd/idlist.[ch].
3922 * Implemented the simple re-key protocol into the server.
3923 Affected files silcd/server.c and silcd/protocol.[ch]. The
3924 re-key will be performed once in an hour, by default.
3926 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3927 Added silc_server_rekey, silc_server_rekey_callback and
3928 silc_server_rekey_final.
3930 * Removed Tunneled flag from the protocol. Updated the code
3931 and the specifications.
3933 * Adde `pfs' field to the SilcIDListData to indicate whether
3934 the PFS is to be performed in the re-key. Affected file is
3937 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3939 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3940 int64 of at least the xintXX size. If void * is less that 4
3941 bytes uint32 * will be used. Defined bool as boolean.
3943 * Changed _ALL_ unsigned long and unsigned int to uint32,
3944 unsgined short to uint16 in the source tree.
3946 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3947 not handle clients that has entry->data.registered == FALSE.
3948 They are not in the network anymore. Affected file is
3951 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3953 * Implemented the sending of the SERVER_SIGNOFF notify in the
3954 server. Affected file is silcd/server.c.
3956 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3957 Added also silc_notify_payload_encode_args into the
3958 lib/silccore/silcnotify.[ch].
3960 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3961 Affected file silcd/packet_receive.c.
3963 * Implemented the SERVER_SIGNOFF notify handling in the client
3964 library. Affected file lib/silcclient/client_notify.c. Also,
3965 implemnted the printing of the SERVER_SIGNOFF info to the
3966 application. Affected file silc/client_ops.c.
3968 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3969 if the deleting was successful. Affected file silcd/idlist.[ch].
3971 * Added support for public key authentication in the connection
3972 authentication protocol in the client library. Affected file
3973 lib/silcclient/protocol.c.
3975 * Changed the server's silc_idlist_get_clients_by_* interface
3976 to support already allocated array so that new entries may be
3977 added to pre-allocated array. Affected file silcd/idlist.[ch].
3978 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3979 and command replies.
3981 * All command reply functions in the server now calls the
3982 pending command callback even if error occured. This way the
3983 error will be delivered to the client as well. Affected files
3984 silcd/command.c and silcd/command_reply.c.
3986 * Fixed INFO command to return local server's info if no server
3987 was provided. Affected file lib/silcclient/command.c.
3989 * Removed RESTART command for good. Updated the code and the
3992 * Rewrote parts of the task system. It is a bit simpler now.
3993 Removed unsued task priorities. The affected files are
3994 lib/silcutil/silctask.[ch].
3996 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Moved the USERS printing from the library to the application.
3999 Affected files lib/silcclient/command.c and silc/client_ops.c.
4001 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Added channel key re-key support. The re-key is perfomed
4006 only by the router and is done once in an hour. Added `rekey'
4007 field to the SilcChannelEntry in the server. Affected files
4008 silcd/server.c and silcd/idlist.h.
4010 * Added silc_task_unregister_by_context into the file
4011 lib/silcutil/silctask.[ch].
4013 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * Added SILC_UMODE_GONE mode to indicate when the client is not
4016 present in the SILC network. Added also support to the local
4017 command AWAY that will set this mode. Added support of showing
4018 "xxx is gone" in WHOIS command. The USERS command shows the
4019 gone status as well.
4021 * Fixed setting server and router operator privileges in the
4022 server's UMODE command. Affected file silcd/command.c.
4024 * Merged the SKE KE1 and KE2 payloads into one payload. The
4025 new KE payload is equivalent to the old KE2 payload.
4027 Cleaned up the SKE Start Payload parsing. It now uses the
4028 simple buffer unformatting to do the parsing. A lot faster
4031 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4032 to the SKE that is used to indicate whether both of the SKE
4033 parties should perform authentication. By default only the
4034 responder performs authentication. By setting this flag also
4035 the initiator must do authentication. By default it is unset
4036 since in normal SKE case, client to server connection, only
4037 the responder should do authentication. When doing SKE between
4038 two clients both should perform authentication. Updated the
4039 code and the protocol specs.
4041 * A little fix to IDENTIFY command in the server. Search the
4042 client first by hash not nickname. Affected file is
4045 * Fixed the silc_client_close_connection to support closing
4046 the client to client connections wihtout deleting too much
4047 data. Affected file lib/silcclient/client.c.
4049 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4050 are received if protocol used to be active but is not anymore
4051 the application would crash due to NULL pointer dereference.
4052 Affected files silcd/server.c and lib/silcclient/client.c.
4054 * Added `hash' field to the SilcClientConnection to include
4055 the hash function negotiated in the SKE protocol.
4057 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4058 to set the channel founder authentication data. A client can
4059 claim the founder rights later by providing the authentication
4060 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4061 This way the channel founder can regain the channel founder
4062 privileges even it is left the channel. This works only on
4063 local server and the client must be connected to the same
4064 server to be able to regain the founder rights. Updated the
4065 protocol specs accordingly.
4067 Added support to the CMODE command in the client to set the
4068 founder auth data. Read the README to see how to set it.
4070 Added support to the CUMODE command to claim the founder
4071 rights. Read the README to see how to do it.
4073 Added support for the founder authentication to the Channel
4074 Entry in the server. Affected file silcd/idlist.h.
4076 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4077 server's CMODE command. Affected file silcd/command.c.
4079 * Added the following new functions into lib/silccore/silcauth.[ch]:
4080 silc_auth_get_method and silc_auth_get_data.
4082 * The server now saves the remote hosts public key to the
4083 SilcIDListData pointer. Affected file silcd/protocol.c.
4085 * The normal server now does not remove the channel entry from
4086 the cache if the founder authentication data is set. It used
4087 to remove it if the founder was the last one on the channel on
4088 the server and left the channel. The auth data is saved and
4089 if the channel is re-joined later the old entry is used with
4090 the old auth data. Affected files silcd/command_reply.c and
4093 * Removed the `pkcs' field from the SilcIDListData structure
4094 in the server; it is not used. Affected file silcd/idlist.h.
4096 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4098 * Fixed packet processing on slow links. Partial packets were
4099 never re-processed because the incoming data buffer was cleared
4100 by the application. Application must not directly clear the
4101 sock->inbuf, the packet processing routines handle it. Fixed
4102 this in client library and in server.
4104 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4106 * Fixed the WHOIS and IDENTIFY send reply function to really
4107 check whether to send list or just one entry. Affected file
4110 * Cleaned up the LEAVE command's channel key distribution. The
4111 affected file silcd/command.c.
4113 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4114 can enforce the channel mode as well. In that case the ID
4115 includes the ID of the server. The code now enforces the
4116 mode change if the router have different mode than the server.
4118 * The notify client operation with CMODE_CHANGE notify can now
4119 return NULL client_entry pointer if the CMODE was not changed
4120 by client. Application must check for this.
4122 * Added <Server ID> argument to INFO command to support server
4123 info fetching by Server ID.
4125 * Added silc_server_announce_get_channel_users to get assembled
4126 packets of channel users of the specified channel. Affected
4127 file silcd/server.[ch].
4129 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4130 was freed underneath the ID Cache.
4132 * Re-announce clients when the server received CHANNEL_CHANGE
4133 notify from the router. Affected file silcd/packet_send.c.
4135 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4137 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4138 crashed since it did not handle the fact that there is no cipher
4139 called "3" and didn't check the error condition. Now fixed.
4141 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4142 flag. It can be used to send message requests.
4144 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4146 * Implemented the RESTART command in the client.
4148 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4149 notice type messages. Added notice printing to the user
4152 * The channel keys are not re-generated if the channel's mode
4153 is PRIVKEY, ie private key on the channel exists. Affected
4154 files silcd/server.c and silcd/command.c.
4156 * Fixed a little bug in channel message delivery when channel
4157 private keys are set in the server. Affected file is
4158 silcd/packet_send.c.
4160 * Changed the setting on channel->on_channel = TRUE from the
4161 silc_client_save_channel_key to the JOIN command reply. The
4162 key payload is not received if the private channel key is set.
4163 Affected file lib/silcclient/command_reply.c and the
4164 lib/silcclient/client_channel.c.
4166 * When the CMODE_CHANGE notify is sent and the channel private
4167 key mode is removed the channel key must be re-generated in
4168 other cells as well. Added this support for the router in the
4169 silcd/packet_receive.c.
4171 * Added new local command NOTICE to send notice message on
4172 channel. Affected file silc/local_command.[ch].
4174 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4176 * Added new local command ME to the client. It is used to send
4177 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4178 some action. Affected file silc/local_command.[ch].
4180 * Changed channel_message and private_message client operations
4181 to deliver the message flags to the application. Added also
4182 the `flags' arguments to the silc_client_send_channel_message
4183 and silc_client_send_private_message functions. Affected file
4186 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4188 * Redefined the Private Message Payload to support private message
4189 keys and to support the new private message flags. Updated
4190 the protocol specs. Flags makes it possible to have for example
4191 CTCP style messages.
4193 * Added new type SilcPrivateMessagePayload and defined an API
4194 for it in the lib/silcclient/silcprivate.[ch].
4196 * Tested private message private keys successfully. Tested the
4197 private message key set, unset and list commands with the new
4200 * Redefined the Channel Message Payload to include the channel
4201 message flags (equal with private message flags) to support
4202 for example CTCP style messages.
4204 * Defined some of the message (for channel and private message)
4205 flags. Updated the protocol specs and added the flags to the
4206 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4208 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4210 * Added SilcKeyAgreementStatus type to the key agreement routines
4211 to indicate the current status and error if one occured.
4212 The status types are defined in the lib/silcclient/silcapi.h.
4214 * Added new local command KEY that is used to set and unset private
4215 keys for channels, set and unset private keys for private messages
4216 with remote clients and to send key agreement requests and
4217 negotiate the key agreement protocol with remote client. The
4218 key agreement is supported only to negotiate private message keys,
4219 it currently cannot be used to negotiate private keys for channels,
4220 as it is not convenient for that purpose.
4222 * Fixed a minor pending callback setting bug in the function
4223 silc_client_get_client_by_id_resolve, now the function works.
4224 Affected file lib/silcclient/idlist.c.
4226 * Added function silc_net_get_local_port to get local bound
4227 port by socket. Added to lib/silcutil/silcnet.[ch].
4229 * Added `sockets' and `sockets_count' fields to the SilcClient
4230 object. They hold the sockets of the listenning sockets in
4231 the client. Listenning sockets may be for example the key
4232 agreement server. Affected file lib/silcclient/client.[ch].
4233 Added functions the silc_client_add_socket and the
4234 silc_client_del_socket. They are exported to the application
4237 * Added ~./silc/clientkeys to support other client's public keys.
4239 * Renamed verify_server_key client operation to verify_public_key
4240 and added one argument to indicate the type of the connection
4241 (server, client etc.).
4243 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Added silc_server_connection_auth_request to handle the
4246 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4247 silcd/packet_receive.[ch].
4249 * Added silc_server_send_connection_auth_request into the
4250 silcd/packet_send.c to send the connection auth request packet.
4252 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4255 * Fixed the public key authentication in responder side in the
4256 server. The `auth_data' pointer includes the SilcPublicKey
4257 not the path to the public key. Affected file silcd/protocol.c.
4259 * Implemented the public key authentication in the initiator side
4260 in the server. Affected file silcd/protocol.c.
4262 * Removed the [RedirectClient] config section from the server
4263 configuration. Is not needed and I don't want to implement it.
4265 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Cleaned up the CMODE command in the server. It now works
4268 correctly and supports all the modes defined in the protocol.
4269 Affected file is silcd/command.c.
4271 * Added `hmac_name' field to the SilcChannelEntry in the server
4272 to hold the default HMAC of the channel. It can be set when
4273 creating the channel (with JOIN command). Affected files
4276 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4277 type to indicate the change of the current cipher and hmac
4278 on the channel. Client can safely ignore the <cipher> argument
4279 (if it chooses to do so) since the CHANNEL_KEY packet will
4280 force the channel key change anyway. The <hmac> argument is
4281 important since the client is responsible of setting the new
4282 HMAC and the hmac key into use.
4284 * Fixed the CMODE command in the client library as well.
4286 * Tested CMODE command in router environment successfully.
4288 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4290 * Show the version of the remote client (or server) when connecting
4291 to the server. It is logged to the log file. Affected file
4292 is silcd/protocol.c.
4294 * Fixed the KILLED notify handling in the client library. The
4295 client must be removed from all channels when receiving the
4298 Also, do not remove the client entry when giving the KILL
4299 command but when the KILLED notify is received.
4301 * Removed silc_idlist_find_client_by_nickname from the server.
4302 Not needed anymore. Affected files silcd/idlist.[ch].
4304 * Implemented the CHANNEL_CHANGE notify type handling to the
4305 server. Affected file silcd/server.c.
4309 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Added silc_server_send_notify_invite to send the INVITE
4312 notify between routers.
4314 * Implemented the INVITE command correctly to the server.
4316 * Implemented the INVITE notify type handling in the server.
4318 * Implemented the INVITE command to the client library and on the
4321 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4323 * Added function silc_server_get_client_resolve to find the
4324 client entry by ID from all ID lists and then resolve it
4325 (using WHOIS) if it cannot be found. Affected file is
4328 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Implemented the BAN command to the client library.
4332 * The JOIN command in the server now checks the invite list
4335 * Changed the silc_command_reply_payload_encode_va and the
4336 silc_command_payload_encode_va to support that if argument is
4337 NULL it ignores and checks the next argument. Affected file
4338 lib/silccore/silccommand.c.
4340 * Added silc_server_send_notify_ban to send the BAN notify
4341 type between routers.
4343 * Chaned the silc_notify_payload_encode to support that if
4344 argument is NULL it ignores and checks the next argument.
4345 Affected file lib/silccore/silcnotify.c.
4347 * Tested ban lists in router environment successfully.
4349 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Implemented BAN command to the server, in silcd/command.[ch].
4353 * Removed the BAN and INVITE_LIST modes from the CMODE command
4356 * Added function silc_string_match to regex match two strings.
4357 Affected files lib/silcutil/silcutil.[ch].
4359 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4361 * Redefined parts of the SilcChannelEntry in the server to support
4362 the new ban and invite lists.
4364 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4366 * Redefined the INVITE command. The same command can be used to
4367 invite individuals to the channel but also to manage the invite
4368 list of the channel (to add to and remove from the invite list).
4369 Updated the protocol specs.
4371 * Added new command SILC_COMMAND_BAN that can be used to manage
4372 the ban list of the channel. Updated the protocol specs.
4374 * Removed the channel modes: the SILC_CMODE_BAN and the
4375 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4376 in the CMODE command. The equivalent features are now available
4377 using INVITE and BAN commands. Updated the protocol specs.
4379 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4380 in the network about change in the current ban list. The notify
4381 type is not used by the client.
4383 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4384 support the invite lists.
4386 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4388 * Added new function silc_string_regexify that converts string
4389 including wildcard characters into regex string that can
4390 be used by the GNU regex library. Added into the file
4391 lib/silcutil/silcutil.[ch].
4393 Added silc_string_regex_combine to combine to regex strings
4394 into one so that they can be used as one regex string by
4395 the GNU regex library. Added into the file
4396 lib/silcutil/silcutil.[ch].
4398 Added silc_string_regex_match to match two strings. It returns
4399 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4401 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4403 * Imported GNU regex to the soruce tree into lib/contrib.
4404 Fixed some compiler warning from the regex.c.
4406 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4408 * Fixed MOTD command in the server to work in router environment.
4410 * Fixed the MOTD command in the client library to support
4411 the server argument in the command.
4413 * Added `nickname_len' argument to the silc_idlist_add_client
4414 in the server, as the `nickname' argument may be binary data
4417 * Added silc_idlist_get_channels to return all channels from
4420 * Implemented LIST command to the server. Affected file is
4423 * Implemented the LIST command to the client library and on the
4426 * Added [<user count>] argument to the LIST command reply.
4427 With private channels the user count is not shown.
4429 * Updated TODO and README.
4431 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * The client entry's data.registered must be TRUE even with
4434 global client entry on global client list. The data.registered
4435 is used to check whether the client is anymore in the network,
4436 for example with WHOWAS command so it must be valid.
4438 * Fixed the WHOWAS command in the server. It now actually works
4439 in router environment. Added function into silcd/command_reply.c
4440 silc_server_command_reply_whowas_save.
4442 * Added silc_idlist_purge function to the silcd/idlist.c
4443 to periodically purge the ID Cache.
4445 * Fixed INFO command in the server. It works now in router
4446 environment. Added <server name> argument to the INFO command
4447 reply. Updated the protocol specs.
4449 * Fixed minor bug in silc_idcache_purge to not purge if the
4450 expire value is zero.
4452 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4453 they were buggy because of the WHOWAS information.
4455 * Fixed local command MSG to handle the async resolving of
4456 the remote client properly. It used to fail the first MSG.
4457 Affected file silc/local_command.c.
4459 * Added `data_len' field to SilcIDCache context.
4461 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Update TODO. Todo in commands in the server.
4465 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4467 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4468 used by routers as broadcast packet to inform other routers
4469 about the changed user mode.
4471 Implemented the notify handling in the server. Affected file is
4472 silcd/packet_receive.c. Added the function
4473 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4475 * Added new generic Channel Payload and deprecated the New Channel
4476 Payload. The New Channel Payload is now the generic Channel
4479 * Added new argument `mode' to the silc_server_send_new_channel
4480 as it is required in the Channel Payload now.
4482 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4483 and created a new and real SilChannelPayload to represent the
4484 new generic Channel Payload. Implemented the encode/decode
4485 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4487 * Added silc_server_get_client_channel_list to return the list
4488 of channels the client has joined for WHOIS command reply.
4489 Affected file silcd/server.[ch].
4491 * Implemented the channel list sending in the WHOIS command reply
4492 in server and in the client.
4494 Implemented the channel list displaying on the user interface
4495 as well. Affected file silc/client_ops.c.
4497 * Added silc_channel_payload_parse_list to parse list of Channel
4498 Payloads. It returns SilcDList list of SilcChannelPayloads.
4499 Client for example can use this function to parse the list of
4500 channels it receives in the WHOIS command reply. The caller
4501 must free the list by calling silc_channel_payload_list_free.
4502 Affected files lib/silccore/silcchannel.[ch].
4504 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * Added one new argument <user mode> to the WHOIS command reply
4507 to return the mode of the user in SILC. Updated the protocol
4510 Implemented it to the server and client.
4512 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4514 * Fixed the mode printing on the user interface on joining.
4515 Affected file silc/client_ops.c.
4517 * Implemented the UMODE command and user modes in general to the
4518 client library and to the user interface.
4520 * Implemented the UMODE command to the server.
4522 * The server now sends UNKNOWN_COMMAND error status if client sends
4523 unknown command. Affected file silcd/command.c.
4525 * All server commands now handle the command identifier the right
4526 way when sending the command reply to the client. The client can
4527 use to identify the command replies with the identifier.
4529 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Added silc_server_get_client_route to resolve the route to
4532 the client indicated by the client ID. Affected file is
4535 * Added silc_server_relay_packet as general function to relay
4536 packet to arbitrary destination. This deprecates functions
4537 like _send_private_message_key, _relay_notify etc. Affected
4538 file is silcd/packet_send.[ch].
4540 Removed silc_server_send_key_agreement,
4541 silc_server_send_private_message_key and
4542 silc_server_packet_relay_notify functions from the file
4543 silcd/packet_send.[ch].
4547 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4548 server. Affected file silcd/packet_receive.[ch].
4550 * Implemented the KILL command to the client. Implemented the
4551 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4552 Affected files lib/silcclient/command[_reply].c and
4553 lib/silcclient/client_notify.c. Implemented the KILL notify
4554 printing in the user inteface.
4556 * Fixed a lot silc_parse_nick memory leaks from the client
4557 library in the file lib/silcclient/command.c.
4559 * Changed the silc_server_send_notify_on_channels's `sender'
4560 argument from SilcSocketConnection to SilcClientEntry to
4561 check the sender as entry and not as connection object and not
4562 to send to the client provided as argument. The affected file
4563 is silcd/packet_send.[ch].
4565 * The notify packets that are destined directly to the client used
4566 to not to be processed by the server. Now changed that and the
4567 server processes all notify packets. After relaying the packet
4568 to the client the notify packet is processed in the server.
4570 * The silc_server_free_client_data now checks whether there is
4571 pending outgoing traffic for the client and purges the data to
4572 the network before removing the client entry.
4574 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4576 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4577 an client is killed from the SILC Network. Updated the protocol
4580 Added new function silc_server_send_notify_killed to the
4581 silcd/packet_send.[ch].
4583 * Added function silc_server_packet_relay_notify to relay notify
4584 packets that are destined directly to a client. In this case
4585 the server does not process the notify packets but merely relays
4586 it to the client. Affected file silcd/packet_send.[ch].
4588 Added also silc_server_packet_process_relay_notify to check
4589 whereto relay the notify. Affected file is
4590 silcd/packet_receive.[ch].
4592 * Implemented the KILL command to the server.
4596 * Added the backup schema desgined last fall to the protocol
4597 specs for everyone to see. The specification is in the
4598 *-spec-xx.txt draft and the packet type definitions for the
4599 backup routers is in *-pp-xx.txt draft. Thusly, added also
4600 new packet type SILC_PACKET_CELL_ROUTERS.
4602 * A big security problem in the implementation discovered. The
4603 signoff of an client did not cause new channel key generation
4604 which it of course should've done. The channel keys must be
4605 always re-generated when client leaves (or signoffs) the channel.
4606 The silc_server_remove_from_channels funtion now handles
4607 the channel key re-generation.
4609 * Added `sender' argument to the silc_server_send_notify_on_channels
4610 to not to send the client provided as argument. Affected file
4611 silcd/packet_send.[ch].
4613 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4615 * Implemented OPER and SILCOPER commands into the server and
4618 * Added silc_auth_verify and silc_auth_verify_data to verify
4619 the authentication directly from the authentication payload.
4620 It supports verifying both passphrase and public key based
4621 authentication. Affected file lib/silccore/silcauth.[ch].
4623 * Added `hash' field to the SilcIDListData structure. It is the
4624 hash negotiated in the SKE protocol. Affected file is
4627 * Slight redesigning of the SilcAuthPayload handling routines.
4628 Do not send SilcPKCS but SilcPublicKey as argument.
4630 * Implemented the public key authentication support to the
4631 serverconfig. The public key is loaded from the provided path
4632 and saved as authentication data to void * pointer. Thus,
4633 changed the unsigned char *auth_data to void *auth_data;
4635 * Fixed SHUTDOWN command to send the reply before the server
4636 is shutdown. :) Affected file silcd/command.c.
4638 * Fixed fatal bug in CONNECT command. The hostname was invalid
4639 memory and server crashed. Affected file silcd/command.c.
4641 * Fixed fatal bug in CLOSE command. The server_entry became
4642 invalid but was referenced later in the command. Affected file
4645 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4647 * Fixed fatal bug in failure packet handling. Server ignored
4648 the failure and thus crashed when it came.
4652 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4655 that the command may be executed only once in (about) 2 seconds.
4656 The old SILC_CF_LAG flag is same but allows command bursts up
4657 to five before limiting.
4659 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4660 server code. Various commands now includes the CF_LAG_STRICT
4661 flag to disallow any kind of miss-use of the command.
4663 * Fixed the silc_buffer_unformat to not to allocate any data
4664 if the length of the data is zero. It used to allocate the
4665 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4667 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4669 * Changed the format of AdminConnection configuration section
4670 in the server. Added username of the admin to the format.
4671 Affected files silcd/serverconfig.[ch].
4673 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4674 to return admin configuration data by host, username and/or
4677 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * Implemented WHOWAS command to the server. Added the functions:
4681 silc_server_command_whowas_parse,
4682 silc_server_command_whowas_send_reply,
4683 silc_server_command_whowas_from_client and
4684 silc_server_command_whowas_from_server
4686 * Added <Client ID> argument to the WHOWAS command reply. Updated
4687 the protocol specs accordingly.
4689 * Implemented WHOWAS command and command_reply to the client
4692 Implemented the WHOWAS printing on the user interface.
4694 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4696 * Added new argument to the WHOWAS command reply, the real name.
4697 It is an optional argument. Updated the protocol specs.
4699 * Added SilcIDCacheDestructor callback that is registered when
4700 the SilcIDCache is allocated. The callback is called when
4701 an cache entry in the ID Cache expires, or is purged from the
4702 cache. Added into lib/silccore/idcache.[ch].
4704 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4705 to destruct the client entries when the cache entry expires.
4706 Other ID Cache's in server and in the client library ignores
4709 * If the ID Cache entry's `expire' field is zero then the entry
4710 never expires. Added boolean `expire' argument to the
4711 silc_idcache_add function in the lib/silccore/idcache.[ch].
4712 If it is TRUE the default expiry value is used.
4714 * Added silc_server_free_client_data_timeout that is registered
4715 when client disconnects. By default for 5 minutes we preserve
4716 the client entry for history - for WHOWAS command.
4718 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4720 * Added support to the server to enforce that commands are not
4721 executed more than once in 2 seconds. If server receives
4722 commands from client more frequently, timeout is registered
4723 to process the commands. Affected file silcd/command.c.
4724 Added new function silc_server_command_process_timeout.
4726 * Changed NICK_NOTIFY handling in client library to check that
4727 if the client's nickname was changed, so there is no need to
4728 resolve anything from the server.
4730 * Removed error printing from the WHOIS and IDENTIFY commands.
4731 If error occurs then it is ignored silently in the client library.
4732 The application, however, may map the received error to
4733 human readable error string. The application currently maps
4734 the NO_SUCH_NICKNAME error to string.
4736 * Made the command status message public to the application. Moved
4737 them from lib/silcclient/command_reply.c to
4738 lib/silcclient/command_reply.h. The application can map the
4739 received command status to the string with the
4740 silc_client_command_status_message function.
4742 * Added check to the server to check that client's ID is same
4743 as the Source ID in the packet the client sent. They must
4746 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4748 * Added dist-bzip hook to the Makefile.am to make bzip2
4749 compressed distributions.
4751 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4753 * Server now enforces the maximum length for the nickname and
4754 the channel as protocol specification dictates. 128 bytes for
4755 nickname and 256 bytes for channel name.
4757 * Moved the WHOIS printing to the application. The client libary
4758 does not print out the WHOIS information anymore, the application
4759 must do it. Renamed silc_client_command_reply_whois_print to
4760 the silc_client_command_reply_whois_save.
4762 The client's idle time is also sent to the application now, and
4763 the idle is shown on screen.
4765 * Added silc_client_command_reply_identify_save to save the
4766 received IDENTIFY entries.
4768 * Do not check for channel private keys in message sending and
4769 reception if the channel does not have the PRIVKEY mode set.
4770 Affected file lib/silclient/client_channel.c.
4772 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4774 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4775 just surfaced after chaning the JOIN procedure.
4777 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Added silc_client_get_clients_by_list to get client entries
4780 from Client ID list, that is returned for example by JOIN
4781 and USERS command replies. The application should use this
4782 function for example when JOIN command reply is received to
4783 resolve the clients already on the channel (library does not
4784 do that anymore as USERS command reply is not used in the JOIN
4785 procedure anymore). Affected files lib/silcclient/silcapi.h and
4786 lib/silcclient/idlist.c.
4788 * JOIN command reply and USERS command reply returns now SilcBuffer
4789 pointers instead of unsigned char pointers when returning
4790 the client list and mode list.
4792 * Added <Client ID> argument to the JOIN command reply, mainly
4793 for the server to identify for which client the command was
4794 originally sent. Updated protocol specs accordingly.
4796 * Added SilcDlist private_key pointer to the SilcChannelEntry
4797 in the client to support the channel private keys. Affected
4798 file is lib/silcclient/idlist.h.
4800 * Added SilcChannelPrivateKey argument to the function
4801 silc_client_send_channel_message so that application can choose
4802 to use specific private ke if it wants to. If it is not provided,
4803 the normal channel key is used, unless private keys are set.
4804 In this case the first (key that was added first) is used
4805 as the encryption key.
4807 * Implemented the support for channel private key handling.
4808 Implemented the following functions:
4810 silc_client_add_channel_private_key,
4811 silc_client_del_channel_private_keys,
4812 silc_client_del_channel_private_key,
4813 silc_client_list_channel_private_keys and
4814 silc_client_free_channel_private_keys
4816 Affected file lib/silcclient/client_channel.c.
4818 * Added the support for the private keys in the channel message
4819 sending and encryption and in the message reception and
4820 decryption. Affected funtions are
4821 silc_client_send_channel_message and silc_client_channel_message.
4823 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4825 * Added SKE's key verify callback to the client library's
4826 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4828 * Removed the statement that server (or router) must send USERS
4829 command reply when joining to the channel so that the client
4830 knows who are on the channel. Instead, the client list and
4831 client's mode list is now sent in the JOIN command reply to the
4832 client who joined channel. This is better solution.
4834 * Added function silc_server_get_users_on_channel and function
4835 silc_server_save_users_on_channel to the silcd/server.[ch].
4837 * Removed function silc_server_command_send_users from the
4840 * Do not show topic on the client library anymore. The topic is
4841 sent in the command reply notify to the application and the
4842 application must show the topic now.
4844 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Added client searching by nickname hash into the IDENTIFY and
4847 WHOIS commands in the server as they were clearly missing from
4848 them. Affected file is silcd/command.c.
4850 * Fixed a bug in private message receiving in the client library.
4851 The remote ID was freed and it wasn't supposed, now it is
4854 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4856 * Minor fix to the channel payload; allocate the data area, as it
4857 needs to be of specific length.
4859 * If the key agreement port is zero then the operating
4860 system will define the bound port. Affected files are
4861 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4863 * Added new function silc_channel_payload_decrypt into the file
4864 lib/silccore/silcchannel.[ch].
4866 * Moved the channel message etc, check from silc_packet_decrypt
4867 to applications. The library calls now a generic
4868 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4869 when the packet is either normal or special. This was done to
4870 allow more wide range of checking that was not allowed when
4871 the code was in library. Now applications can do virtually any
4872 checks to the packet and return to the library the decision how
4873 the packet should be processed. Affected files are
4874 lib/silccore/silcpacket.[ch].
4876 Added silc_server_packet_decrypt_check to the server and
4877 silc_client_packet_decrypt_check to the client library.
4879 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4880 to send with specified source and destination information.
4882 * Channel message delivery between routers was broken after the
4883 channel key distribution was fixed earlier. The channel key
4884 was used be to distributed to other routers as well which is not
4885 allowed by the protocol. Now this is fixed and channel keys
4886 really are cell specific and the channel message delivery between
4887 routers comply with the protocol specification.
4889 * Fixed various commands in server to check also the global list
4890 for the channel entry and not just the local list. The affected
4891 file silcd/command.c.
4893 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4895 * Added assert()s to buffer formatting and unformatting routines
4896 to assert (if --enable-debug) when error occurs. Affected
4897 file: lib/silcutil/silcbuffmt.c.
4899 * Changed to auto-reconnect to check whether the remote host is
4900 router and register the re-connect timeout if it is. It used
4901 to check that whether we are normal server, but router must do
4902 auto-reconnect with another router as well. Affected file
4905 * Removed the [<key len>] option from CMODE command as the cipher
4906 name decides the key length, nowadays. See the defined ciphers
4907 from the protocol specification.
4909 * Added [<hmac>] option to the CMODE command to define the HMAC
4910 for the channel. Added SILC_CMODE_HMAC channel mode.
4912 * Added [<hmac>] option for the JOIN command so that user can
4913 select which HMAC is used to compute the MACs of the channel
4916 * Added Hmac field to the Channel Message Payload. The integrity
4917 of plaintext channel messages are now protected by computing
4918 MAC of the message and attaching the MAC to the payload. The
4919 MAC is encrypted. Now, it is clear that this causes some
4920 overhead to the size of the packet but rationale for this is that
4921 now the receiver can verify whether the channel message decrypted
4922 correctly and also when private keys are set for the channel the
4923 receiver can decrypt the packet with several keys and check from
4924 the MAC which key decrypted the message correctly.
4926 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4927 lib/silccrypt/silccipher.[ch].
4929 * Added silc_hash_len to return the digest length into the
4930 lib/silcrypt/silchash.[ch].
4932 * Rewrote parts of Silc Channel Payload interface in the
4933 lib/silccore/silcchannel.[ch]. The encode function now also
4934 encrypts the packet and parse function decrypts it.
4936 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4938 * Fixed a minor formatting bug in the SKE's key material processing.
4939 It actually might have processed the keys wrong way resulting
4942 * Redefined the mandatory HMAC algorithms and added new algorithms.
4943 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4944 and hmac-md5 truncated to 96 bits. The mandatory is now
4945 hmac-sha1-96. Rest are optional (including the one that used
4946 to be mandatory). Rationale for this is that the truncated HMAC
4947 length is sufficient from security point of view and can actually
4948 make the attack against the HMAC harder. Also, the truncated
4949 HMAC causes less overhead to the packets. See the RFC2104 for
4952 * Added new [hmac] configuration section. The SKE used to use
4953 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4954 is of course wrong. The official names that must be proposed in
4955 the SKE are the ones defined in the protocol specification
4956 (hmac-sha1-96 for example). The user can configure any hmac
4957 using any hash function configured in the [hash] section. At
4958 least, the mandatory must be configured.
4960 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4962 * Added HMAC list to the SKE proposal list. It has now both
4963 hash algorithm list and HMAC list. This makes the protocol
4964 incompatible with previous versions. The SKE now seems to work
4965 the way it is supposed to work, for the first time actually.
4967 * Defined plain Hash algorithms to the protocol specification.
4970 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4972 * Implemented support for key agreement packets into the server.
4973 Added functions silc_server_key_agreement and
4974 silc_server_send_key_agreement. Other than these functions,
4975 server has nothing to do with this packet.
4977 * Added support for private message key packets into the server.
4978 Added functions silc_server_private_message_key and
4979 silc_server_send_private_message_key.
4983 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4984 called in the protocol's final callback instead in the END
4985 protocol state. This makes a little more sense and in the same
4986 time in client we can use the same protocol routines for normal
4987 key exchange and to key agreement packet handling as well.
4989 * Added to both client's and server's KE protocol context the
4990 SilcSKEKeyMaterial pointer to save the key material. We will
4991 bring the key material to the protocol's final callback by doing
4992 this. The final callback must free the key material.
4994 * Added SKE's packet_send callback into client's KE protocol
4995 context so that the caller can choose what packet sending function
4996 is used. This way we can use different packet sending when
4997 doing normal SKE when doing key agreement packet handling (in
4998 the key agreement packet handling we do not want to encrypt
5001 * Implemented the responder side of the key agreement routines
5002 in the client. The client can now bind to specified port and
5003 accept incoming key negotiation. The key material is passed
5004 to the application after the protocol is over.
5006 * Implemented the processing of incoming Key Agreement packet
5007 in the client. Added function silc_client_key_agreement to
5010 * Implemented the intiator side of the key agreement routines
5011 in the client. The client can now initiate key agreement with
5012 another remote client. The key material is passed to the
5013 application after the protocol is over.
5015 * Created client_keyagr.c to include all the key agreement
5018 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5019 SILC_TASK_CALLBACK except that it is not static.
5021 * Created client_notify.c and moved the Notify packet handling
5022 from the client.[ch] into that file.
5024 * Created client_prvmsg.c and moved all private message and
5025 private message key routines from the client.[ch] into that file.
5027 * Create client_channel.c and moved all channel message and
5028 channel private key routines from the client.[ch] into that file.
5030 * Changed silc_client_get_client_by_id_resolve to resolve with
5031 WHOIS command instead of IDENTIFY command, in the file
5032 lib/silclient/idlist.c.
5034 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5036 * Implemented the SKE's responder side to the Client library.
5038 * When FAILURE is received to the protocol do not trust it
5039 blindly. Register a timeout to wait whether the remote closes
5040 the connection as it should do it, only after that process the
5041 actual failure. This was changed to both client and server.
5043 * Added client_internal.h to include some of the structures
5044 there instead of client.h in lib/silcclient/.
5046 * Added function silc_task_unregister_by_callback to unregister
5047 timeouts by the callback function.
5049 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Some "Incomplete WHOIS info" errors has been appearing on the
5052 log files. Took away the entry->userinfo check from WHOIS
5053 reply sending. The entry->userinfo is now " " if client did not
5054 provide one. I thought this was fixed earlier but something
5055 is wrong still. Let's see if the error still appears.
5057 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5059 * Fixed a minor bug in the login when the channel key is
5060 re-generated in the server. It used to generate the key in
5061 wrong order and thus caused problems in the channel traffic.
5063 * Fixed a minor bug in channel key distsribution after
5064 KICK command. The key was not sent to the router even though
5067 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5069 * Added silc_ske_process_key_material_data as generic routine
5070 to process any key material as the SILC protocol dictates. The
5071 function is used by the actual SKE library but can be used by
5072 applications as well. This relates to the private message keys
5073 and the channel private keys since they must be processed the
5074 same way the normal SILC session keys. The protocol dictates
5075 this. Affected files: lib/silcske/silcske.[ch].
5077 Added also silc_ske_free_key_material to free the
5078 SilcSKEKeyMaterial structure.
5080 * Defined silc_cipher_set_key function to set the key for
5081 cipher without using the object's method function. The affected
5082 files: lib/silccrypt/silccipher.[ch].
5084 * Implemented silc silc_client_add_private_message_key,
5085 silc_client_add_private_message_key_ske,
5086 silc_client_del_private_message_key,
5087 silc_client_list_private_message_keys and
5088 silc_client_free_private_message_keys functions in the
5091 Added functions silc_client_send_private_message_key to send
5092 the Private Message Key payload and silc_client_private_message_key
5093 to handle incoming Private Message Key payload.
5095 * Added Cipher field to the Private Message Key payload to set
5096 the cipher to be used. If ignored, the default cipher defined
5097 in the SILC protocol (aes-256-cbc) is used.
5099 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5101 * Removed lib/silcclient/ops.h file.
5103 Redefined parts of the SILC Client Library API. Created new
5104 file silcapi.h that deprecates the ops.h file and defines the
5105 published Client Library API. Defined also private message key
5106 API and channel private key API into the file.
5108 This is the file that the application must include from the
5109 SILC Client Library. Other files need not be included by
5110 the application anymore.
5112 * Added new key_agreement client operation callback and also
5113 defined the Key Agreement library API for the application.
5115 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5117 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5118 is used by clients to request key negotiation between another
5119 client in the SILC network. If the negotiation is started it
5120 is performed using the SKE protocol. The result of the
5121 negotiation, the secret key material, can be used for example
5122 as private message key.
5124 Implemented the Key Agreement payload into the files
5125 lib/silccore/silauth.[ch].
5127 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5129 * Redefined ciphers for the SILC protocol. Added some new ciphers
5130 and defined the key lengths for the algorithms. Changed the
5131 code accordingly. The default key length is now 256 bits.
5133 * Fixed SKE key distribution function silc_ske_process_key_material
5134 when the key length is more than 128 bits. The default key
5135 length in SILC is now 256 bits.
5137 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5138 to indicate unsupported algorithm.
5140 * Renamed rijndael.c to aes.c and all functions as well.
5142 * Fixed a long standing channel key setting bug in client library.
5143 Weird that it has never surfaced before.
5145 * Fixed bug in channel deletion. If the entire channel is removed
5146 then it must also delete the references of the channel entry
5147 from the client's channel list as the client's channel entry and
5148 the channel's client entry share same memory.
5150 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * Implemented CONNECT and SHUTDOWN commands in the client.
5154 * Implemented CLOSE command to the client.
5156 * Added the function silc_idlist_find_server_by_name into the
5157 files silcd/idlist.[ch].
5159 Added the function silc_idlist_find_server_by_conn into the
5160 files silcd/idlist.[ch].
5162 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5164 * DIE command was renamed to SHUTDOWN. Updated the both code
5167 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5168 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5170 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5173 * Added function silc_server_create_connection function to create
5174 connection to remote router. My server implementation actually
5175 does not allow router to connect to normal server (it expects
5176 that normal server always initiates the connection to the router)
5177 so the CONNECT command is only good for connecting to another
5180 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5182 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5183 or some other client was kicked from the channel.
5185 Implemented the handling of the notify type to both client
5188 Implemented silc_server_send_notify_kicked to send the KICKED
5189 notify. It is used to send it to the server's primary router.
5191 * Implemented the KICK command into server and client.
5193 * Added `query' argument to the silc_idlist_get_client function
5194 to indicate whether to query the client from server or not if
5197 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5198 to indicate that the client is not channel founder.
5202 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5204 * Removed the rng context from SilcPacketContext structure and
5205 changed that the packet routine uses the Global RNG API.
5207 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5209 * Added support for quit message that client can "leave" on the
5210 channel when it quits the SILC. It is ditributed inside the
5211 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5213 Added silc_server_free_client_data that will take the
5214 signoff message as argument.
5216 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5218 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * Updated parts of the protocol specification to keep it up
5223 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5225 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5226 payloads in one packet.
5228 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5229 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5230 use now the new List flag.
5232 * Also deprecated the following packet types: REPLACE_ID,
5233 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5235 * Added list support for Notify packet in server.
5237 * Added silc_server_send_notify_channel_change to send the
5238 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5239 the silc_server_send_replace_id.
5241 * Added silc_server_send_notify_nick_change to send the
5242 NICK_CHANGE notify type. Deprecates the function
5243 silc_server_send_replace_id.
5245 * Added silc_server_send_notify_join to send the JOIN notify type.
5246 Deprecates the function silc_server_send_new_channel_user.
5248 * Added silc_server_send_notify_leave to send LEAVE notify type.
5249 Deprecates the function silc_server_send_remove_channel_user.
5251 * Added silc_server_send_notify_cmode and
5252 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5253 types. Deprecates the silc_server_send_set_mode function.
5255 * Added SERVER_SIGNOFF notify type to indicate that server has
5256 quit. This means that all clients on the channel from that
5257 server will drop. This can be also used when netsplit happens.
5259 Deprecated REMOVE_ID packet type since it is not needed anymore
5262 Added silc_server_send_notify_server_signoff to send the
5263 SERVER_SIGNOFF notify type. Deprecates the function
5264 silc_server_send_remove_id.
5266 Added also silc_server_send_notify_signoff to send the
5267 SIGNOFF notify type.
5269 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5270 SILC protocol from this day on. Changed the protocol
5271 specification as well.
5273 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5274 notify type. It is used between routers to notify about
5275 topic changes on a channel.
5277 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5280 * Partly updated the protocol specification to comply with the
5281 changes now made. It is still though a bit outdated.
5283 * The JOIN notify type now takes one extra argument <Channel ID>.
5284 The packet used to be destined to the channel but now the
5285 JOIN type may be sent as list thus it is impossible to
5286 destine it to any specific channel. By adding this argument
5287 it is again possible.
5289 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5291 * Added CREDITS file. The CHANGES and CREDITS file will appear
5292 in the distribution as well.
5294 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5296 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5297 types in the server's silcd/packet_receive.c.
5299 * Implemented CMODE and CUMODE to work in router environment.
5301 * Fixed minor encoding and decoding buglet from the
5302 lib/silccore/silcmode.c.
5304 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5307 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5309 * Changed all SilcConfigServer* and silc_config_server* to
5310 SilcServerConfig* and silc_server_config*, respectively.
5313 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5315 * Associated the ID (client or server ID) to the Authentication
5316 Payload to avoid any possibility of forging. Updated the
5317 protocol specification and the code accordingly.
5319 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5321 * The RSA key length is now save to the RsaKey context in the
5322 key generation process in lib/silccrypt/rsa.c. The key length
5323 is now used to figure out the maximum size of the block allowed
5324 to be encrypted/signed.
5326 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5327 is equivalent to the silc_mp_mp2bin but does not allocate any
5330 * Changed silc_mp_mp2bin API to take length argument. If it is
5331 non-zero then the buffer is allocated that large. If zero, then
5332 the size is approximated using silc_mp_sizeinbase, which however
5335 * Created Global RNG API which is global RNG that application can
5336 initialize. After initializing, any routine anywhere in the
5337 code (including library) can use RNG without allocating a new
5338 RNG object. This was done to allow this sort of use of the
5339 RNG in code that has no chance to allocate RNG object. All
5340 applications currently allocate this and many routines in the
5341 library use this. Affected file lib/silccrypt/silcrng.[ch].
5343 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5344 it to use the Global RNG API.
5346 * Defined Authentication Payload into protocol specification that
5347 is used during SILC session to authenticate entities. It is
5348 used for example by client to authenticate itself to the server
5349 to obtain server operator privileges.
5351 Implemented this payload into the lib/silccore/silcauth.[ch].
5352 Implemented also routines for public key based authentication
5353 as the new protocol specification dictates.
5355 Moved definitions of different authentication methods from
5356 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5358 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5359 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5360 silc_pkcs_verify_with_hash functions into the file
5361 lib/silccrypt/silcpkcs.[ch].
5363 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5365 * The client entry's userinfo pointer must be always valid.
5366 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5367 will fail since it requires the userinfo. Now, the userinfo
5368 is allocated as "" if actual userinfo does not exist. Actually,
5369 it must exist and it is totally Ok to drop client connections
5370 that does not announce the userinfo. However, we will make
5371 this workaround for now.
5373 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5374 to return the remote port by socket.
5376 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5378 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5379 SILC_SERVER_PENDING_EXEC and added an new macro
5380 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5381 data or when error occurs while processing the pending command.
5383 Added new argument `destructor' into silc_server_command_pending
5384 and to the SilcServerCommandPending object. This destructor is
5385 now called after calling the pending callback or if error occurs
5386 immediately. If error occurs the actual pending callback won't
5387 be called at all - only the destructor. The destructor may be
5388 NULL if destructor is not needed.
5390 All this applies for client library code as well. Similar
5391 changes were made there as well for the pending commands.
5393 In the client, the application must now allocate the
5394 SilcClientCommandContext with the silc_client_command_alloc
5397 * Added reference counter to the SilcServerCommandContext. Added
5398 function silc_server_command_alloc and silc_server_command_dup
5401 Same type of functions added to the client library for the same
5404 * Removed the cmd_ident from IDListData away since it is now
5405 global for all connections. It is the command identifier used
5406 in command sending and with pending commands. The affected file
5409 * Added reference counter to the SilcSocketConnection objecet to
5410 indicate the usage count of the object. The object won't be
5411 freed untill the reference counter hits zero. Currently only
5412 server uses this, and client ignores it. The client must be
5413 set to use this too later. The affected files are
5414 lib/silccore/silcsockconn.[ch]. Added also the function
5415 silc_socket_dup to increase the reference counter.
5417 This was mainly added because it is possible that the socket
5418 is removed underneath of pending command or other async
5419 operation. Now it won't be free'd and proper DISCONNECTING
5420 flags, etc. can be set to avoid sending data to connection that
5421 is not valid anymore.
5423 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5424 the connection. After that it sets SILC_SET_DISCONNECTED.
5425 It is, however, possible that the socket data is not still freed.
5426 The silc_server_packet_process now checks that data is not
5427 read or written to connection that is DISCONNECTED. The socket
5428 get's freed when the reference counter hits zero.
5430 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5432 * Changed the client operation API: channel_message operation's
5433 `sender' is now the client entry of the sender, not the nickname
5434 and the `channel' is the channel entry, not the channel name.
5436 In the private_message operation the `sender' is now also the
5437 client entry of the sender not the nickname.
5439 Affected file is lib/silcclient/ops.h and all applications
5440 using the client operations.
5442 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5444 * Moved the calling of ops->connect() from connect_to_server_final
5445 into receive_new_id functin since that is the point when the
5446 client is actually allowed to send traffic to network. The
5447 affected file is lib/silcclient/client.c.
5449 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5451 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5452 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5453 (if needs broadcasting) instead of broadcasting the packets one
5454 by one which would make a burst in the network traffic.
5456 * Added `broadcast' argument to the functions in silcd/server.[ch]
5457 silc_server_create_new_channel[_with_id] to indicate whether
5458 to send New Channel packet to primary router.
5460 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5462 * Added new function into the silcd/server.[ch] files:
5463 silc_server_create_new_channel_with_id to create new channel with
5464 already existing Channel ID.
5466 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5467 lib/silccore/silcpacket.h. This packet is used t send list of
5468 Set Mode payloads inside one packet. Server uses this to set
5469 the modes for the channels and clients on those channels, that it
5470 announced to the router when it connected to it. The protocol
5471 specification has been updated accordingly.
5473 * The silc_server_new_channel did not handle the packet coming
5474 from normal server as it normally does not send that. However,
5475 when it announces its channels it does send it. Implemented
5476 the support for that.
5478 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5479 into the file lib/silccore/id.h.
5481 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5483 * Fixed memory leaks in the functions silc_idlist_del_client,
5484 silc_idlist_del_channel and silc_idlist_del_server in the file
5485 silcd/idlist.c. All of those leaked like a sieve.
5487 * Fixed some small memory leaks in the client's function
5488 silc_client_notify_by_server.
5490 * Added functions into silcd/server.c: silc_server_announce_clients,
5491 silc_server_announce_channels and silc_server_announce_server.
5492 These functions are used by normal and router server to announce
5493 to its primary router about clients, channels and servers (when
5494 router) that we own. This is done after we've connected to the
5497 These functions effectively implements the following packet types:
5498 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5499 and SILC_PACKET_NEW_ID_LIST.
5501 * Added new functions into the silcd/packet_receive.[ch]:
5502 silc_server_new_id_list, silc_server_new_channel_list and
5503 silc_server_new_channel_user_list to handle the incoming
5504 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5506 * Added support of changing Channel ID in the function
5507 silc_server_replace_id. If the server that announces a channel
5508 to the router already exists in the router (with same name but
5509 with different Channel ID), router is responsible to send
5510 Replace ID packet to the server and force the server to change
5511 the Channel ID to the one router has.
5513 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5514 client that the Channel ID has been changed by the router. The
5515 normal server sends this to the client. Client must start using
5516 the new Channel ID as the channel's ID.
5518 Implemented handling of this new type into lib/silcclient/client.c
5519 into the function silc_client_notify_by_server.
5521 * Added new function silc_idlist_replace_channel_id into the files
5522 silcd/idlist.[ch] to replace the Channel ID.
5524 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5526 * Call silc_server_command_identify_check always when processing
5527 the IDENTIFY command in silcd/command.c
5529 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5532 send keepalive packets. The packet can be sent by clients,
5533 servers and routers.
5535 Added function silc_socket_set_heartbeat into the file
5536 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5537 If not set, the heartbeat is not performed. The actual
5538 heartbeat is implemented in the low level socket connection
5539 library. However, application is responsible of actually
5542 Added silc_server_send_heartbeat to send the actual heartbeat
5543 packet into silcd/packet_send.[ch]. Server now performs
5544 keepalive with all connections.
5546 * Added silc_task_get_first function into lib/silcutil/silctask.c
5547 to return the timeout task with shortest timeout. There was a bug
5548 in task unregistration that caused problems. TODO has been
5549 updated to include that task system must be rewritten.
5551 * The client library will now resolve the client information when
5552 receiving JOIN notify from server for client that we know but
5553 have incomplete information.
5555 * Rewrote parts of silc_server_remove_from_channels and
5556 silc_server_remove_from_one_channel as they did not remove the
5557 channel in some circumstances even though they should've.
5559 * Encryption problem encountered in server:
5561 The LEAVE command used to send the Channel Key packet to the
5562 router immediately after generating it. However, the code
5563 had earlier sent Remove Channel user packet but not immediately,
5564 ie. it was put to queue. The order of packets in the router
5565 was that Channel Key packet was first and Remove Channel User
5566 packet was second, even though they were encrypted in the
5567 reverse order. For this reason, MAC check failed. Now, this
5568 is fixed by not sending the Channel Key packet immediately but
5569 putting it to queue. However, this is more fundamental problem:
5570 packets that are in queue should actually not be encrypted
5571 because packets that are sent immediately gets encrypted
5572 actually with wrong IV (and thus MAC check fails). So, packets
5573 that are in queue should be encrypted when they are sent to
5574 the wire and not when they put to the queue.
5576 However, the problem is that the current system has not been
5577 designed to work that way. Instead, the packet is encrypted
5578 as soon as possible and left to the queue. The queue is then
5579 just purged into wire. There won't be any fixes for this
5580 any time soon. So, the current semantic for packet sending
5583 o If you send packet to remote host and do not force the send
5584 (the packet will be in queue) then all subsequent packets to the
5585 same remote host must also be put to the queue. Only after the
5586 queue has been purged is it safe again to force the packet
5589 o If you send all packets immediately then it safe to send
5590 any of subsequent packets through the queue, however, after
5591 the first packet is put to queue then any subsequent packets
5592 must also be put to the queue.
5594 Follow these rules and everything works fine.
5596 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Added new function silc_server_remove_clients_by_server to
5599 remove all client entries from ID list when the server connection
5600 is lost. In this case it is also important to invalidate all
5601 client entires as they hold the invalid server entry. This
5602 fixes fatal bug when server has lost connection and will reconnect
5605 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5607 * Made some sanity checks to silc_server_daemonise like to check
5608 whether the requested user and group actually exists.
5610 * Added sanity check to SKE's silc_ske_responder_finish to check
5611 that the public and private key actually is valid.
5613 * Invalidate the client's nickname when receiving Replace ID
5614 packet and the Client ID is being replaced. This means that the
5615 server will query the nickname if someone needs it (client)
5618 * Sort the ID Cache in client library when the ID Cache data
5619 has changed (needs sorting).
5621 * Do not allow for SILC client to create several connections to
5622 several servers. The client does not support windows right now
5623 and generating multiple connections causes weird behaviour.
5625 Irssi-silc client does support windows and can handle several
5626 connections without problems, see: www.irssi.org and SILC plugin.
5628 * Fixed some places where client was added to the IDList. The
5629 rule of thumb is following (in order to get everything right):
5630 If the client is directly connected local client then the
5631 `connection' argument must be set and `router' argument must be
5632 NULL to silc_idlist_add_client function. If the client is not
5633 directly connected client then the `router' argument must
5634 bet set and the `connection' argument must be NULL to the
5635 silc_idlist_add_client function.
5637 * The funtion silc_server_packet_send_local_channel actually did
5638 not check whether the client was locally connected or not. It
5639 does that now. Fixed a bug related to LEAVE command.
5641 * Fixed Remove Channel User payload parsing bug in server's
5642 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5644 * The server's silc_server_save_channel_key now checks also the
5645 global ID list for the channel as it might not be in the local
5646 list. Fixed a bug related to LEAVE command.
5648 * Is this the end of the [<unknown>] buglet that has been lurking
5649 around for a long time? A little for loop fix in server's
5650 silc_server_command_whois_parse that is used by both IDENTIFY
5651 and WHOIS command. At least, this was a clear bug and a cause
5652 of one type of [<unknown>] buglet.
5654 * WHOIS and IDENTIFY commands call the function
5655 silc_server_command_[whois/identify]_check function even if
5656 we are not router server.
5658 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5660 * Added --with-gmp configuration option. If set the GMP
5661 is always compiled in the SILC source tree. If not set then
5662 it is checked whether the system has the GMP3 installed. If
5663 it has then the GMP won't be compiled (the system's headers
5664 and library is used), if it doesn't have it then the GMP is
5665 compiled in the SILC source tree.
5667 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5669 * Changed RSA private exponent generation to what PKCS #1
5670 suggests. We try to find the smallest possible d by doing
5671 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5672 not security fix but optimization.
5674 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Added new config entry [Identity] to fork the server and run
5677 it as specific user and group. A patch from Bostik.
5679 * Imported Dotconf configuration library into lib/dotconf.
5680 This will be used to create the SILC configuration files later.
5681 It will appear in the distsribution after this commit.
5683 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5685 * A big code auditing weekend happening. Auditing code for
5686 obvious mistakes, bugs and errors. Also, removing any code
5689 Removed files for being obsolete:
5691 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5692 inline in the file lib/silcutil/silcbuffer.h)
5694 o lib/silcutil/silcbufutil.c (the header has inline versions)
5696 Changed code to fix possible error conditions:
5698 o The buffer formatting routines now check that the destination
5699 buffer really has enough space to add the data. This applies for
5700 both buffer formatting and unformatting
5701 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5702 unformatting was changed to accomodate following rules:
5703 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5704 sent to the function while XXX_*STRING will not allocate or copy
5705 the data into the buffer. Instead it sets the pointer from the
5706 buffer into the pointer sent as argument (XXX_*STRING used to
5707 require that the pointer must be allocated already). This change
5708 makes this whole thing a bit more consistent and more optimized
5709 (note that the data returned in the unformatting with XXX_*STRING
5710 must not be freed now). The routines return now -1 on error.
5712 o Tried to find all code that use buffer_format and buffer_unformat
5713 and added return value checking to prevent formatting and
5714 especially unformatting errors and possible subsequent fatal
5717 o Changed ske->x and ske->KEY to mallocated pointers in
5718 lib/silcske/silcske.h. Fixed possible data and memory leak.
5720 o Added return value checking to all *_parse* functions. Fixed
5721 many memory leaks as well.
5723 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5724 so that buffer overflows would not happen. All code now also
5725 checks the return value as it can fail.
5727 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5729 * Added reconnection support to server if the normal server looses
5730 its connection to the router (for example if router is rebooted).
5731 The server performs normal reconnection strategy implemented
5732 to the server. Affected file silcd/server.c.
5734 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5736 * Added new packet type SILC_PACKET_SET_MODE that is used to
5737 distribute the information about changed modes (for clients,
5738 channels and clients channel modes) to all routers in the
5739 network. Updated the protocol specification accordingly.
5741 Added functions into silcd/packet_send.c and
5742 silcd/packet_receive.c: silc_server_send_set_mode,
5743 silc_server_set_mode.
5745 Added new files silcmode.[ch] into lib/silccore that implements
5746 the encoding and decoding of Set Mode Payload. Added new type
5747 SilcSetModePayload. Moved the definitions of different modes
5748 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5750 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5752 * Oops, a little mistake in server's connection authentication
5753 protocol. The protocol is not ended with FAILURE but with
5754 SUCCESS if the authentication is Ok. :) Affected file is
5757 * Implemented NICK_CHANGE notify handling in server in the file
5758 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5759 the local clients on the channel. After the changing nickname
5760 in router environment snhould work and the [<unknown>] nickname
5761 should appear no more.
5763 The silc_server_replace_id function that receives the Replace ID
5764 payload now sends the NICK_CHANGE notify type also in the file
5765 silcd/packet_receive.c
5767 * Changed WHOIS and IDENTIFY command to support the maximum amount
5768 of arguments defined in protocol specs (3328 arguments). This
5769 fixed a bug that caused problems when there were more than three
5772 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5774 * Added extra parameter, command identifier, to the
5775 silc_client_send_command so that explicit command identifier
5778 Changed that ID list routines uses specific command identifier
5779 when sending WHOIS/IDENTIFY requests to the server so that they
5780 can be identified when the reply comes back.
5782 Affected files lib/silcclient/command.[ch],
5783 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5785 * Added `sender' argument to silc_server_packet_send_to_channel
5786 to indicaet the sender who originally sent the packet to us
5787 that we are now re-sending. Ignored if NULL. Affected file
5788 silcd/packet_send.[ch].
5790 * Added some server statistics support in silcd/server_internal.h
5791 SilcServerStatistics structure and around the server code. Also
5792 send some nice statistics information when client is connecting
5795 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Fixed channel ID decoding in server's JOIN command reply in
5798 silcd/command_reply.c
5800 * Fixed braodcasting of replace ID payload to not to send it if
5801 we are standalone server in silcd/packet_receive.c.
5803 * Fixed all channel message sending routines to not to send
5804 packets to clients that has router set, since they are routed
5805 separately in the same function earlier. Affects file
5806 silcd/packet_send.c and all channel packet sending functions.
5808 * In USERS reply, res_argv[i] are not allocated, the table
5809 is allocated. Thus changed that free the table, not its
5812 * In server's whois_check and identify_check if the client is
5813 locally connected do not send any WHOIS commands - they are not
5816 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5818 * Fixed some minor bugs in client when sending WHOIS command. The
5819 arguments was in wrong order.
5821 * Removed statis function add_to_channel from server in
5822 silcd/command.c that was previously used with the joining but
5825 * Tested USERS command in router environment successfully with two
5826 routers, two servers and two clients.
5828 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5830 * Reorganized the USERS command and command reply in client library
5831 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5832 When the command is given by user we register a pending command
5833 callback that will reprocess the command after the reply has been
5834 received from the server. When reprocessing the packet we then
5835 display the information. Thus, the USERS information is displayed
5836 now in the command callback instead of in the command reply
5837 callback. The processing of the command is same as previously
5838 when server has sent the command reply in the JOINing process.
5840 * Added to USERS command in silcd/command_reply.c to join the client,
5841 we didn't use to know about, to the channel after we've created
5842 a client entry for it. Also, for clienet we did know already still
5843 check whether it is on the channel or not and add it if not.
5845 * Removed silc_server_command_join_notify as the function and its
5848 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5850 * Changed the client's pending command handling to the same as the
5851 server's pending command handling. It is also now possible to
5852 execute command reply functions from other command reply
5853 function as the function callbacks for commands and command
5854 replies are one and same. The pending commands are not static
5855 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5856 in client connection context. Thus, pending commands are server
5857 connection specific as it is convenient.
5859 Changed the function silc_client_command_pending and
5860 silc_client_command_pending_del and added new function
5861 silc_client_command_pending_check. Removed the
5862 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5865 * Added cmd_ident, current command identifier, to the client
5866 connection context in lib/silcclient/client.h to keep track on
5867 command identifiers used in command sending. Client's command reply
5868 function handling now supports the mandatory command identifiers.
5870 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5871 funtions in client to fully support pending command callbacks.
5873 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5874 as one of the arguments to the application in the command reply
5877 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5878 before first releasing SILC but came back. Now it is removed again
5879 and should come back nomore. The FORWARDED flag was used only
5880 by the JOINing procedure by forwarding the command packet to router.
5881 Now, the JOINing procedure has been changed to more generic (due
5882 to various router environment issues) and FORWARDED is not needed
5883 anymore for anything. The protocol specification is yet to be
5886 Now, removed silc_server_packet_forward from server and the flag
5887 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5889 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5891 * Renamed NAMES command to USERS command. The NAMES was named that
5892 due to historical reasons. Now it is renamed. Also, rewrote
5893 parts of the USERS command. The nickname list is not sent anymore
5894 by the server. Only Client ID and mode lists are sent in the USERS
5895 command. Changed this also to the protocol specification.
5897 The client now resolves the names and stuff after it receives
5898 the USERS list from the server when joining to the channel.
5900 * WHOIS and IDENTIFY commands has been changed to support multiple
5901 Client ID's per command. One can now search for multiple users
5902 in the network by sending only one WHOIS or IDENTIFY command.
5903 Changed the code and the protocol specifications.
5905 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5906 uses silc_server_command_whois_parse to parse the request. */
5908 * If normal server, do not parse the WHOIS and IDENTIFY requests
5909 before sending it to the router. Saves some time.
5911 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * Fixed JOIN command on client library. Wrong number of arguments
5914 used to crash the client.
5916 * Added silc_server_channel_has_global function to check whether
5917 channel has global users or not.
5919 * Added silc_server_channel_has_local function to check whether channel
5920 has locally connected clients on the channel.
5922 * The silc_server_remove_from_one_channel now checks whether the
5923 channel has global users or not after given client was removed from
5924 the channel. It also checks whether the channel has local clients
5925 on the channel anymore. If it does not have then the channel entry
5926 is removed as it is not needed anymore.
5928 * The silc_server_notify now checks on JOIN notify whether the joining
5929 client is one of locally connected or global. If it is global then
5930 the channel has now global users on the channel and that is marked
5931 to the channel entry. Also, it now saves the global client to
5932 global list who is joining and JOINs it to the channel. This is
5933 for normal server, that is.
5935 Changed silc_server_send_notify_on_channel,
5936 silc_server_packet_relay_to_channel and
5937 silc_server_packet_send_to_channel check if we are normal server
5938 and client has router set (ie. global client) do not send the
5939 message to that client, as it is already routed to our router.
5941 * Implemented LEAVE notify type handling in silc_server_notify
5944 * Tested LEAVE command in router environment successfully. Tested
5945 with two routers, two servers and two clients.
5949 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5951 * Implemented SIGNOFF notify type handling in silc_server_notify
5954 * silc_server_remove_id now removes the client entry from all channels
5955 it has joined and thusly sends SIGNOFF notify type.
5957 * Rewrote the NAMES list generation in server by removing two excess
5958 loops. The lists are created now inside one loop.
5960 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5962 * silc_server_remove_channel_user checks now also global list
5963 for channel and client.
5965 * silc_server_new_channel_user checks now both local and global
5966 list for channel and client. Fixed a bug in client id decoding.
5967 Used to decode wrong buffer.
5969 * silc_server_channel_message checks now both local and global
5970 list for channel entry.
5972 * Tested channel joining (hence JOIN) in router environment
5973 successfully. Tested with two routers, two servers and two
5976 * Tested channel message sending in router environment successfully.
5978 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5980 * Added silc_server_save_channel_key into server.[ch] to save the
5981 received channel key in Channel Key payload processing. It is
5982 also used in JOIN command reply handling.
5984 Equivalent function silc_client_save_channel_key added into
5985 client.[ch] into client library.
5987 * Changed JOIN command reply to send information whether the channel
5988 was created or not (is existing already) and the channel key
5989 payload. Changed protocol specs accordingly.
5991 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5992 the request was sent by ID and not by nickname. Crashed on
5995 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5997 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5998 now correctly save the received data.
6000 * silc_server_free_sock_user_data now notifies routers in the
6001 network about entities leaving the network.
6003 At the same time implemented functions silc_server_remove_id
6004 and silc_server_send_remove_id to receive and send REMOVE_ID
6005 packets. The packet is used to notify routers in the network
6006 about leaving entities. The ID removed will become invalid in
6009 * Added function silc_idlist_del_server into server. Removes and
6010 free's server entry from ID list.
6012 * silc_server_private_message function now checks, if we are router,
6013 that the destination ID really is valid ID, naturally.
6015 * In router when NEW_ID packet is received (for new client) the
6016 hash of the Client ID is saved in the ID Cache but the
6017 client->nickname is set to NULL, instead of putting the hash
6020 IDENTIFY command now also checks that client->nickname must be
6021 valid. If it is not if will request the data from the server who
6022 owns the client. Added new function
6023 silc_server_command_identify_check.
6025 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6026 to set the command to already allocated Command Payload.
6028 * Tested private message sending in router environment with two
6029 routers, two servers and two clients. Fixed minor bugs and now
6032 * Fixed segfault from client's NAMES command. Used to crash if
6035 * Forwarded packets must not be routed even if it is not destined
6036 to the receiver. Changed server code comply with this.
6038 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6040 * Added `require_reverse_mapping' boolean value to ServerParams
6041 structure. If TRUE (not default) the server will require that
6042 the connecting host has fully qualified domain name.
6044 If the reverse mapping is not required and hostname could not be
6045 found the IP address is used as hostname.
6047 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6049 * Implemented version string checking to both client and server.
6050 The check is incomplete currently due to the abnormal version
6051 strings used in development version of SILC.
6053 * Changed all command functions in server to use the new
6056 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Changed char *data to unsigned char *data in ID Cache system to
6059 support binary data as ID Cache data. Changed code to support
6060 binary data in lib/silccore/idcache.c.
6062 * Renamed silc_server_packet_relay_command_reply to
6063 silc_server_command_reply as it is normal packet receiving
6064 function. Rewrote the function to accept command replys for
6065 servers and not only for clients.
6067 * Mark remote router always as registered server if we are connecting
6068 to it. Otherwise, commands sent by the router to us are ignored.
6070 * All ID List find routines now returns the ID Cache Entry pointer
6071 as well if requested.
6073 * WHOIS command works now in router environment, tested with two
6074 routers, two servers and two clients.
6076 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6077 in router environment (as it is almost equivalent to WHOIS) but
6078 hasn't been tested thoroughly. Added new functions:
6080 silc_server_command_identify_parse
6081 silc_server_command_identify_send_reply
6082 silc_server_command_identify_from_client
6083 silc_server_command_identify_from_server
6085 * Disabled route cache adding because adding two different ID's with
6086 same IP replaces the old cache entry thus giving wrong route.
6087 The entry->router->connection is always the fastest route anyway
6088 so route cache may not be needed. Of course, new routes maybe
6089 established after receiving the ID when the entry->router->connection
6090 might not be anymore the most optimal.
6092 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6094 * Add route cache for received ID for fast routing.
6096 * Added silc_server_packet_route to route received packet on router
6097 that is not destined to us.
6099 * Renamed silc_server_get_route to silc_server_route_get.
6101 * Added id_string and id_string_len fields into SilcServer to
6102 include encoded ServerID for fast comparing without excess
6103 encoding of the ID's.
6105 * Cleaned up WHOIS command on server side. Added following static
6108 silc_server_command_whois_parse
6109 silc_server_command_whois_check
6110 silc_server_command_whois_send_reply
6111 silc_server_command_whois_from_client
6112 silc_server_command_whois_from_server
6114 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6115 arguments in command replies. All command functions should be
6116 updated to use this macro.
6118 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6120 * Minor typo fixes on command reply handling on server.
6122 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6124 * Added silc_server_command_add_to_channel internal routine to add
6125 the client to the channel after router has created the channel and
6126 sent command reply to the server.
6128 * Added generic silc_server_send_command to send any command from
6131 * Use static buffer with ID rendering instead of duplicating data.
6133 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6135 * Fixed a channel user mode bug when joining to a channel server gave
6136 everybody channel founder rights, oops.
6138 * We mark ourselves as the router of the incoming server connection
6139 if we are router ourselves. This way we can check in some packet
6140 sending functions whether it is locally connected server. For
6141 incoming router connections we put NULL.
6143 * For router sending packets locally means now always sending the
6144 packet cell wide; to local clients and local servers. For normal
6145 server sending packet locally means sending it to only local
6148 * Fixed the JOIN command to really work in router environment. If the
6149 channel is created it is always created by the router. Router is
6150 also responsible of making the initial joining to the channel,
6151 sending JOIN notify to the sending server and distributing
6152 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6153 does not exist server doesn't do anything else but forward the
6154 command to the router which performs everything.
6156 * Added silc_server_send_channel_key function to send the Channel Key
6159 * Added silc_server_create_channel_key to create new channel key. The
6160 channel key is now re-generated everytime someone joins or leaves
6161 a channel, as protocol dictates. Note: channel->key_len is the
6164 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6167 packet_receive.[ch] to separate packet sending and receiving
6168 routines. The server.[ch] now includes everything else including
6169 actual packet processing (writing and reading data) and other
6172 Renamed silc_server_private_message_send_internal to
6173 silc_server_send_private_message. The routine is still though
6174 used only to relay private messages as server does not send
6175 private messages itself.
6177 Renamed silc_server_new_channel to silc_server_create_new_channel
6178 and added new function sicl_server_new_channel that handles the
6179 incoming New Channel packet. Added also new sending function
6180 silc_server_send_new_channel to send New Channel Payload.
6182 * Added new function silc_server_notify to process incoming notify
6183 packet to the server/router. Server may then relay the notify
6184 to clients if needed.
6186 * Added new function silc_server_new_channel_user to process incoming
6187 New Channel User packet. Router will redistribute the packet and
6188 send JOIN notify to its local clients and locally connected servers
6189 if needed. Normal server will send JOIN notify to its local client
6190 on same channel when received this packet. Added also corresponding
6191 sending function silc_server_send_new_channel_user to sent the
6194 * Added boolean route argument to send_notif_to_channel and
6195 packet_send_to_channel functions to attempt to route the packet
6196 if it is TRUE and send only locally if it is FALSE.
6198 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6200 * silc_server_replace_id now broadcasts the received replace ID
6201 packet if it is not broadcast packet already. The router must
6202 broadcast to inform other routers about changed ID.
6204 * Added backpointer to server's router into SilcServer context in
6205 silcd/server_internal.h.
6207 * Fixed silc_server_packet_broadcast to send correct broadcast
6210 * The channel key is now distributed to the local client as soon
6211 as it is received from the router (in router environment) so that
6212 no other packet may be sent for the channel until client has
6215 * silc_server_remove_channel_user now broadcasts the received
6216 Remove Channel User packet if it is not broadcast packet already.
6217 The router must broadcast to inform other routers about removed
6220 * Added users field into SilcPacketContext that is a reference count
6221 of the context. One can increase the reference count by calling
6222 silc_packet_context_dup which is now changed to just increase the
6223 reference count instead of duplicating the data. The reference
6224 count is decresed by calling silc_packet_context_free that will
6225 free the data after the reference count hits zero.
6227 For now on the packet context and everything allocated into it
6228 (including the raw packet from network) must be freed by calling
6229 the new silc_packet_context_free function. Added also new function
6230 silc_packet_context_alloc that must be used now to allocate the
6231 context. This also means that if a routine is asynchronous from
6232 silc_[client/server]_packet_parse_type the packet context must
6233 be duplicated by calling silc_packet_context_dup. Otherwise it
6234 gets free'd after silc_[client/server]_packet_parse_type returns.
6235 Also, one must remember that if packet is duplicated then its
6236 reference count must be decresed by calling the free function as
6237 many times as it was duplicated.
6239 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6240 from both client and server.
6242 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6244 * Made joining to a channel working in router environment.
6246 * Cleaned up JOIN command on server side and create function
6247 silc_server_command_join_channel internal routine to make the
6250 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6252 * Changed silc_command_pending list to SilcDList. Also, added
6253 `ident' field to SilcServerCommandPending structure to identify
6254 the reply and to call correct callback.
6256 Added silc_server_command_pending_check function to replace the
6257 corresnponding macro. The silc_command_pending list is not
6260 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6261 to set identifier to previously allocated Command Payload. It
6262 is used to set identifier for command when resending Command
6265 * Added silc_command_payload_encode_payload to encode Command
6266 Payload buffer from SilcCommandPayload structure.
6268 * Added silc_argument_payload_encode_payload to encode Argument
6269 payload buffer from SilcArgumentPayload structure.
6271 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6273 * Changed WHOIS command to support router connection on server side.
6274 The whois request is always sent to router unless the server is
6275 standalone server. After server has received the reply from the
6276 router will it send the reply to the client.
6278 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6279 broadcast received broadcast packet. The function is used only
6280 by router. The broadcast packet is always sent to the router's
6283 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6284 render given ID to printable string, for log files for example.
6286 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6288 * Made basic router to router connections working. At least they
6289 can now connect to each other but nothing really works the way
6290 they are supposed - yet.
6292 * Added new initiator token to RouterConnection configuration
6293 file in silcd/serverconfig.[ch]. It is used to tell whether we
6294 are the initiator to the remote router or whether we'll expect
6295 the other end to connect.
6297 * Moved registering of listener task to silc_server_init, hence
6298 the server starts listenning as soon as it is run, even if it
6299 does not have connections to other routers. Let's see how well
6302 * Changed default connection retry timeouts for more suitable in
6305 * Removed cipher and such arguments from silc_idlist_add_client
6306 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6307 Added new function silc_idlist_add_data to add the keys and stuff
6310 * Added SilcIDListData structure and added it to SilcClientEntry
6311 and SilcServerEntry as their first field in the structure. This
6312 way we can explicitly cast the ID entries to the SilcIDListData
6313 structure and get common data for the entries. In past, we had
6314 to first check what type of connection it is and then cast it to
6315 correct ID entry type. Now, we can directly cast the opaque
6316 pointer to the SilcIDListData (no matter what ID entry it actually
6317 is) and get the data needed.
6319 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6321 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6322 in some circumstances even if threre were timeout tasks, though not
6323 IO tasks, but tasks anyway. Now fixed.
6325 * Defined SilcServerConnection structure to hold connection specific
6326 stuff about directly connected servers and routers. The definition
6327 is currently in silcd/server_internal.h. I thought about having
6328 a bit more important role fro this struct but for now it is used
6329 only when connecting to other server (or router actually).
6331 * Added connecting retry support in server when connecting to
6332 router(s). The retry feature implement exponential backoff
6333 algorithm. Also, added SilcServerParams structure to hold default
6334 parameters for server. For now, it include these retry settings
6335 and are hard coded. After server is moded to be as Silc Server
6336 Library this structure will be more important.
6338 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6340 * Changed client librarys channel->clients table to SilcList and
6341 changed code accordingly.
6343 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6345 * Changed client's channel table to SilcList and changed code
6346 accordingly. Also changed SilcChannelClientEntry to include back-
6347 pointer to the channel so that client entry can use that structure
6348 as list as well and we have fast cross-reference to the channel.
6349 This change dramatically decreased the complexity of channel
6350 handling with client entry and vice versa (removed one extra
6351 loop when searching for channel entry from many functions).
6353 * Changed server->sim from table to SilcDList and changed code
6356 * NAMES command can now be used from user interface. It will show
6357 the user list on the channel, neatly.
6359 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6360 Code now saves realname of the user if it becomes available.
6362 * Renamed configure.in to configure.in.pre and made ./prepare
6363 script to automatically add correct version string to
6364 configure.in which it creates from configure.in.pre.
6366 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6368 * NAMES command reply now shows users mode with the nickname when
6371 * Moved silc_client_ch[u]mode[_char] functions from
6372 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6373 place sucks, they are utility functions and should be in some
6376 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6378 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6381 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6385 * Added TRQ (efficient deque and list library) into lib/trq. This is
6386 a very good list library that is currently used in the SILC. Defined
6387 SilcList API over the library because I didn't like the API very
6388 much. See lib/trq/silclist.h for the API and examples of how to
6389 use the API. Fixed various places in the code to use the new
6390 SilcList API. The SilcList is meant for lists that has a structure
6391 already defined as a list. It is not suitable to add just some
6392 context to the list (in TRQ, the context is the list actually).
6394 So, I defined SilcDList that can be used for the purpose where
6395 predefined list structure does not exit. This can be used as
6396 such list. Now some context just can be added to the SilcDList.
6397 Currently this list is not used in the SILC just yet, though there
6398 are a lot places where this can replace dynamically allocated
6399 tables and I will fix these places, later, to use SilcDList.
6400 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6401 and use TRQ internally).
6403 Also fixed some annoying warning messages that the original TRQ
6404 code generated. Also minor changes to TRQ's Makefile.in.
6406 * Added support for querying by Client ID to both WHOIS and
6407 IDENTIFY commands into server, as required by the protocol.
6409 * Removed method function pointers from SilcBuffer structure. They
6410 weren't used to anything and just increased the context size for
6411 no good reason. This change also made silc_buffer_alloc and
6412 silc_buffer_free functions inline functions.
6414 * Disabled command flooding detection support until it's fixed so
6415 that it accepts commands in but does not execute them more than once
6418 * Added silc_net_localhost(), to return local hostname, into
6419 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6420 that must be initialized before calling silc_client_init.
6422 * Added new function: silc_server_send_notify_on_channels to send
6423 notify messages to all channels client has joined. It is assured
6424 that the message is sent only once per client.
6426 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6427 lib/silcutil/silcutil.[ch] as silc_format function. The new
6428 function is generic and is used by server as well, not only by
6429 the logging routines.
6431 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6432 the provided version string was not acceptable. Added new function:
6433 silc_ske_check_version into lib/silcske/silcske.h. The function
6434 must be implemented by the application (client or server) and it
6435 does not reside in the SKE library. The function checks the version
6436 string remote end sent.
6438 * Added back pointers (to opaque context and to SilcSocketConnection)
6439 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6441 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6442 duplicate packet context structure.
6444 * Changed `notify' client operation to send same arguments as client
6445 receives from server except for ID's. ID's are mapped to correct
6446 ID entry and that is returned. Also, if channel entry is not sent
6447 by server but the notify is for channel the channel entry is sent
6448 to application (otherwise application doesn't know that it is for
6449 channel (library gets it from packet's Destination ID)).
6451 * Added silc_client_remove_from_channels into client library to
6452 remove a client from all channels it has joined to. Used when
6453 received SIGNOFF notify from server. Added also new function
6454 silc_client_replace_from_channels to replace old ID entry with
6455 new ID entry on all channels. Used when received NICK_CHANGE
6458 * Fixed ID Cache list handling in silc_idlist_get_client in
6459 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6460 to get (or query) client by ID.
6462 * Updated TODO list.
6464 * Added connection authentication status message defined by the
6465 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6466 support for these into the code in client and server side.
6468 * Added generic function silc_client_send_command to send any command
6469 with variable argument list. Application should use this function
6470 to send commands if the command functions provided by the library
6471 does not suite for the application's user interface needs.
6473 * Added new `failure' client operation. Application is notified about
6474 received failure packet if client is executing a protocol. In this
6475 case the protocol's execution has failed.
6477 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6478 is required by the protocol.
6480 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6481 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6484 * Added status flag to SilcSKE object to indicate realtime status
6485 of the SKE protocol.
6487 * Application receives now exactly same command reply arguments as
6488 the library receives from server. However, if ID is received the
6489 corresponding ID entry is returned to the application (eg. Client
6490 ID is mapped to correct SilcClientEntry entry and that is returned).
6491 Changed command_reply client operation due to this change.
6493 * Changed all ID's in commands and in command replys as ID Payloads.
6494 Change affected both client and server side codes.
6496 All ID's sent in SILC network (with execption of ID's in SILC
6497 Packet header) are sent in ID Payload to support variable length
6500 * Server now notifies nick changes and notifies all clients on
6501 the channels about the new nickname (about the new Client ID,
6504 * Implemented CMODE command to change channel modes. Supports all
6505 channel modes defined by the protocol specs except ban and invite
6506 lists. (Also, private channel key mode is supported but support for
6507 setting private channel key in client is missing, thus, this mode
6508 has no effect on client side (except that server requires that the
6509 client uses private channel key and normal channel traffic does not
6512 Also, invite mode works per se, but INVITE command does not work
6513 yet correctly, so you can set channel as invite only channel but
6514 inviting clients to the channel does not work (it is yet to be
6515 thought what's the best way to do it).
6517 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6518 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6519 Implemented CUMODE command to change user's mode on the channel.
6520 Supports all modes defined by the protocol specs.
6522 * Added NAMES command reply to return users modes on the channel.
6524 * Removed unnecessary and slow ciphers from lib/silccrypt.
6526 * Set SO_KEEPALIVE option to connection sockets by default.
6528 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6530 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6531 redefined the Notify Payload into protocol specs.
6533 * Added silc_id_payload_parse_id to get ID directly from raw
6536 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6538 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6539 accept searching by Client ID as well.
6541 * Added support for LEAVE and SIGNOFF notify types in client library.
6543 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6544 to parse ID Payload from raw data.
6546 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6548 * Added flags parameter into silc_ske_assemble_security_properties
6549 function in lib/silcske/silcske.[ch].
6551 * Changed notify client operation to fit better for notify messages
6552 sent by server. The notify payload received from server is now
6553 passed to the application (after parsing it to SilcNotifyPayload).
6554 It is application's responsibility to retrieve the arguments
6555 from the payload and show the message the way it wants. The message
6556 sent by server is implementation specific.
6558 * Changed public keys to comply with the protocol specification.
6559 Old public keys are not supported anymore and are not compatible.
6561 * Removed nickname from Channel Payload as the latest draft removed
6562 it. The client must resolve the nickname from the NAMES command
6563 reply received when it joined the channel.
6565 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6567 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6569 * Fixed some errors in protocol specification drafts.
6571 * Created lib/silccore/silcnotify.c to implement Notify Payload
6572 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6573 generic payloads described by protocol specifications. The file
6574 includes implementations for ID Payload and Argument Payload.
6576 * Changed Command Payload implementation to use the new Argument
6577 Payload. Changed command_xxxx_payload to command_payload_xxxx
6578 to comply with SILC coding conventions.
6580 * Added suppport for Argument Payload handling in Notify Payload
6581 implementation as protocol requires it. Added the new support
6582 into server and client lib as well.
6584 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6586 * Added support for multiple nicknames on same channel. [n] is
6587 added locally to the nickname if there are more than one same
6588 nicknames on the channel.
6590 * Server now sends all nicknames that matched WHOIS request.
6591 Client also shows the list received from server.
6593 * Added TOPIC command to client side. User can now set and show
6594 current topic on channel.
6596 * Added MOTD command to client and server. Also, server sends the
6597 motd when client connects to the server.
6599 * Changed version strings to comply ISO 8601.
6601 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6603 * Fixed protocol error handling in client library. It should now
6604 cope even if the SKE fails for some reason.
6606 * Made new protocol specification drafts for submitting to IETF.
6608 * Implemented TOPIC command to server in silcd/command.c.
6610 * Added two new notify types into lib/silccore/silcnotify.h:
6611 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6612 notify nickname change and topic setting/change on a channel.
6614 * API change of command_reply operation in client library. The
6615 application gets now the status type received from server as well.
6617 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6619 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6621 * Cras fixed and optimized the packet handling even further and
6622 it should work now. Minor change to the prototype of function
6623 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6625 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6627 * Added new function into lib/silcutil/silcschedule.[ch]:
6628 silc_schedule_with_fd to select() a specified fd. The function
6629 returns after timeout expires or data arrives or goes. The
6630 function is used by packet routines to wait that all data is
6631 received from network.
6633 * Fixed data reading from network in lib/silccore/silcpacket.c.
6634 The code now assures that all data is read from the fd and then
6635 continues packet processing. This was a bug fix since the code
6636 used to drop some data in some circumstances.
6638 * Added new function into lib/silcclient/client.[ch]:
6639 silc_client_start_key_exchange to start key exchange after
6640 connection has been established to server. The code internally
6641 now uses this funtion but its main purpose was to provide it
6642 for applications that perform their own connecting. After
6643 application has created a connection it merely calls this
6644 function to start the key exchange between client and server.
6645 The library takes care of everything else after that.
6647 Updated also lib/silcclient/README to explain the usage of
6650 * Do not send to application information that connection has
6651 been established. Application gets notified it by connect
6654 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6656 * Applied cras's patch to add silc_schedule_one function. The
6657 function runs scheduler once and returns.
6659 * Fixed the scheduler after cras messed it up. The timeout
6660 handling works now as it's supposed to work.
6662 * Added into lib/silccore/ silcnotify.h to include notify
6663 message types support. Changed silc_server_send_notify*
6664 functions, in server.[ch], to support those new notify types.
6665 Added the support for the notify types into client library,
6666 as well. Added new notify client operation into ops.h in
6669 * Changed silc_server_packet_send_to_channel to send normal
6670 packets instead of just channel message packets. The function
6671 is now used to send the notify packets to channels. It is not
6672 used to send channel message packets anymore, as server never
6675 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6676 va_arg()s as it seems to require it nowadays. I guess, if SILC
6677 is compiled with older va_arg() the new code should work anyway.
6679 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6681 * Splitted core library. Core library (lib/silccore) includes
6682 now only SILC protocol specific core (and common) components.
6683 Created new utility library (lib/silcutil) that includes more
6684 generic purpose stuff. The stuff for util library was taken
6685 from the old core library. This was minor and easy split.
6687 * Created SILC Client Library (lib/silcclient) that includes
6688 implementation of the SILC client without user interface. This
6689 was major move from silc/ directory. The code has been changed
6690 so that it is transparent towards the user interface. The
6691 silc/ directory includes now the same user interface as before
6692 and it uses the new client library. Read lib/silcclient/README.
6693 Basicly, the client library performs everything else related
6694 to SILC except user interface handling. Also, configuration
6695 files are considered to be part of user interface and library
6696 does not handle them.
6698 This change also changed a lot of structures, function naming etc.
6699 Most important change was that SilcClientWindow object was
6700 renamed to SilcClientConnection in the client library. Created
6701 also new file lib/silcclient/ops.h. Also added new files
6702 silc/local_command.[ch] and silc/client_ops.[ch].
6704 All these changes were made to make it easier for user interface
6705 designers to create what ever user interface for the SILC client
6708 It is also expected that the server will be moved to lib
6709 directory as well and SILC Server Library will be created;
6710 sometimes in the future.
6712 * Removed Local commands from lib/silccore/silccommand.h as
6713 they are application specific and new client library does not
6714 handle any of those anymore.
6716 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6717 old client implementation in silc/.
6719 * Added support for callback functions in SILC_LOG_* macros.
6720 Application can now set its own callbacks that will be called
6721 instead of using the default functions that will always print
6722 the debug messages to stderr (or stdout). Also, debugging can
6723 now be disabled by setting silc_debug to FALSE and re-enabled by
6724 setting it to TRUE. Note, that logging will still work even
6725 if debugging is disabled.
6727 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6728 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6729 silc_log_reset_debug_callbacks.
6731 * To enable debugging in silc client one must give now -d
6732 option on command line.
6734 * Changed silc_schedule_init to automatically allocate task queues
6735 if they are not allocated before calling it.
6737 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6739 * Added GMP 3.1 into math library.
6741 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6743 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6744 a channel in SILC network. The packet is used by servers and
6745 routers to notify other routers that user has left a channel.
6746 This little feature was missing until now. Added the feature
6747 to protocol specification as well.
6749 Added functions: silc_server_send_remove_channel_user and
6750 silc_server_remove_channel_user into server.[ch].
6752 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6753 lib/silccore/silcpacket.h. However, they are not implemented
6756 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6758 * Fixed joining to a channel and sending channel messages
6759 between server and router. The channel message sending should
6760 now work inside a cell.
6762 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6764 * Fixed the private message sending between server and router.
6765 The private message sending should now work inside a cell.
6767 * Added silc_server_replace_id into server.[ch] to replace
6768 existing ID in the SILC network.
6770 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6771 and silc_idlist_replace_server_id into idlist.[ch] in server.
6773 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6775 * Fixed the server to server connections. Server can again now
6776 connect to router. Router to router connections probably does
6779 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6781 * Added dynamic protocol registering support. Now protocols can
6782 registered and unregistered on the fly. Patch by cras.
6784 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6786 * Added lib/contrib directory to hold routines that some platforms
6787 don't have but are needed by SILC.
6789 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6790 into lin/contrib to provide getopt() and getopt_long() for
6791 those who don't have it.
6793 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6795 * Added AWAY command to client. When away message is set and
6796 client receives a private message packet the client automatically
6797 replies to the sender with the away message.
6799 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6800 bug seemed to be the cause of recent problems when compiling
6803 * Added version detection support to SKE protocol specification
6804 and added the new changes to the SKE implementation as well.
6805 There were other minor changes in the SKE protocol as well.
6807 Many changes in lib/silcske/silcske.[ch] and in
6808 lib/silcske/payload.[ch].
6810 * Added ^U functionality, clear input line. Patch from cras.
6812 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6814 * Mainly small bugfixes on core library. Fixed some debugging
6815 logging and buffer overflow in silclog.c.
6817 * Updated config.sub and config.guess on the distribution tree.
6819 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6821 * Added command lagging support in server. Client may execute
6822 commands now only once in two seconds.
6824 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6826 * Optimized packet reception. MAC computation and checking is now
6827 also more optimized. A lot previously duplicated code is now
6828 used as generic by both client and server.
6830 * Fixed key pair generation in clientutil.c
6832 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6834 * Added into lib/silccore/silcbufutil.[ch] new function;
6835 silc_buffer_realloc.
6837 * Moved generic packet sending/encryption functions to
6838 lib/silccore/silcpacket.[ch] from client and server. Some
6839 rewriting of the functions.
6841 * Moved all generic packet reception/decryption functions to
6842 lib/silccore/silcpacket.[ch] from client and server. The
6843 packet processing is now much cleaner in both client and server.
6844 These were major changes in both client and server.
6846 * Created many common functions in server to do packet sending.
6847 Previously code were duplicated a lot, this has been removed
6850 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6852 * Rewrote major parts of the ID cache system. Don't know
6853 whether it is better now or not but at least the API is more
6856 * Major rewrite on ID cache stuff on client because of the ID
6857 cache API changes. Added idlist.c to client.
6859 * Also major rewrite on ID cache stuff on server as well.
6860 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6861 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6862 in hand, instead they are all put into the ID cache system now.
6863 All server_idlist_* routines uses ID cache now instead of
6864 traversing its own lists (those lists does not exist anymore).
6865 SilcIDList though still exists. Also, SilcXXXEntry's are
6868 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6870 * Finally made the SKE implementation compliant to the protocol
6871 specification. All mp integers are now binary encoded as
6872 opposed being HEX encoded.
6874 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6877 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6878 functions: silc_[encode/decode]_pem. Also added function
6879 silc_encode_pem_file to PEM encode with newlines ('\n') for
6882 * SILC public keys are now encoded either PEM or binary. Same
6883 option is for private keys as well. By default private keys
6884 are binary encoded and public keys PEM encoded. Silly HEX
6885 encoding were removed.
6887 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6888 function to create fingerprints.
6890 * Fixed a bug in SHA1; does not change the original data anymore.
6892 * Partly implemented INFO command on client and server side.
6893 Fixed CLEAR command. Changes to SERVER command; show current
6894 server(s) when giving command without arguments. Added
6895 VERSION command to client.
6897 * Added check to server that unregistered connections cannot
6898 execute commands (unless it is specificly allowed).
6900 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6902 * Fixed screen refresh.
6904 * Fixed channel joining bug from client. On some circumstances
6905 client tried to join to a channel it had already joined.
6907 * Added public key verification process into client's protocol.c.
6908 The client now verifies the public key from user and saves
6909 it into ~./silc/serverkeys/ directory.
6911 Added into: clientutil.[ch]: silc_client_verify_server_key.
6913 * Changed SKE protocol's silc_ske_initiator_finish function
6914 to accept callback function that verifies the received public
6915 key. Removed old silc_ske_verify_public_key function.
6917 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6919 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6920 silc_pkcs_private_key[_data]_set.
6922 * Made the password and public authentication more cleaner in
6923 server's protocol.c.
6925 * Removed historic and obsolete protocol `channel_auth' from
6926 both client and server.
6928 * Removed wrong way of sending command status messages from
6929 server to client in server's command.c. The old way violated
6930 protocol specification.
6932 Changes to silccore/silccommand.[ch]: removed
6933 silc_command_encode_status_payload -> not needed anymore,
6934 changed silc_command_encode_payload_va to accept extra
6935 argument on variable argument list. The argument type must
6936 now be provided to the function. Also, added new function:
6937 silc_command_encode_reply_payload_va which is same as
6938 normal command_encode_payload_va except command status type
6939 is provided as extra argument.
6941 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6943 * Added ~./silc directory handling. The directory includes the
6944 public and private keys for the client.
6946 Added silc_client_check_silc_dir, silc_client_create_identifier
6947 and silc_client_load_keys.
6949 * Implemented SILC protocol compliant public key. Added public
6950 and private key saving to and loading from files.
6952 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6953 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6954 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6955 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6956 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6958 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6959 silc_pkcs_load_[public/private]_key.
6961 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6963 * Added silc_server_get_route (route.[ch]) to get connection
6964 data for the fastest route for given ID.
6966 * Implemented INVITE command on client and server. The command
6967 were re-defined in the SILC Protocol Specification and the
6968 implementation now complies with the specification.
6970 * Implemented PING command on client and server.
6972 * Implemented NAMES command on client and server. The server side
6973 supports currently only normal server not router server yet.
6974 Some changes to NAMES definition in SILC protocol specification.
6976 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6978 * Implemented LEAVE command on client and server.
6980 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6981 again. This change was made to the protocol as well. Server
6982 should not violate the protocol specification anymore.
6984 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6986 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6987 was tested. SOCKS4 was not but should work anyway.
