1 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed the file transfer's key agreement payload to include
4 zero port also if the hostname is NULL because it could not
7 Call file transfer monitor callback now also if error occurs
8 during key agreement protocol.
10 Changed the silc_client_file_send interface to return the
11 SilcClientFileError instead of session id. The session ID
12 is returned into pointer provided as argument.
14 Check that the file exists locally before sending the
15 file transfer request at all.
17 Affected file lib/silcclient/client_ftp.c, silcapi.h.
19 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
20 error than can occur while key agreement protocol. Affected
21 file lib/silcclient/silcapi.h.
23 * Fixed the event_mode CMODE handler to not crash when mode
24 is changed and +k mode is set in the channel. Affected file
25 irssi/src/silc/core/silc-channels.c.
27 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
28 SILC_LOG_WARNING to give out Warning and not Error. Affected
29 file lib/silcutil/silclog.c.
31 * Fixed the channel message payload decryption in the function
32 silc_channel_message_payload_decrypt to not modify the original
33 buffer before it is verified that the message decrypted
34 correctly. Otherwise, next time it is called with correct
35 channel key it won't encrypt since the payload is corrupted.
36 Affected file lib/silccore/silcchannel.c.
38 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
40 * Do not constantly resize the window. A fix patch by cras.
41 Affected file irssi/src/fe-text/screen.c.
43 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
45 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
46 Affected file lib/silcutil/silcnet.c.
48 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
50 * Fixed a bug in hash table internal routine for traversing
51 the table with foreach callback. The current entry may
52 become invalid in the callback but it was referenced after
53 the callback returned.
55 Do not allow auto rehashing of hash table during the
56 silc_hash_table_foreach operation, for same reasons as it is
57 not allowed for SilcHashTableList. Affected files are
58 lib/silcutil/silchashtable.[ch].
60 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
62 * Defined DLLAPI into silcincludes.h and silcwin32.h for
63 Win32 DLL. extern's in header files are now declared with
66 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
68 * Fixed private message handling. It used some old code that
69 caused the client to crash. Affecte file is
70 lib/silcclient/client_prvmsg.c.
72 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
74 * Added function silc_client_add_channel,
75 silc_client_replace_channel_id, and removed functions
76 silc_client_new_channel_id and silc_idlist_get_channel_by_id
79 * Added cross reference of the joined channels to the
80 SilcClientEntry, and changed the SilcChannelEntry's
81 users list to SilcHashTable. The affected files are
82 lib/silcclient/idlist.[ch].
84 * Fixed a bug in hash table tarversing. While the hash table
85 is traversed with SilcHashTableList the table must not be
86 rehashed. It is now guaranteed that auto rehashable tables
87 are not rehashed while tarversing the list. Also defined that
88 silc_hash_table_rehash must not be called while tarversing
89 the table. Added function silc_hash_table_list_reset that must
90 be called after the tarversing is over. The affected files are
91 lib/silcutil/silchashtable.[ch].
93 * Changed all hash table traversing to call the new
94 silc_hash_table_list_reset in server and in client library.
96 * Added function silc_client_on_channel to return the
97 SilcChannelUser entry if the specified client entry is joined
98 on the specified channel. This is exported to application as
99 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
101 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
103 * Fixed founder regaining problem with JOIN command on normal
104 server. The notify for mode change must be sent always and
105 not only if !cmd->pending. Affected file silcd/command.c.
107 * Fixed the WHOWAS command's reply sending to support the
108 lists correctly. Affected file silcd/command.c.
110 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
112 * When sending JOIN command to router for processing the
113 sender's old command identifier was not saved back to the
114 sender's command context, fixed now. The affected file is
117 * Create the key in JOIN command of the router did not return
118 the channel key, added check for this. Affected file is
121 * Fixed a channel ID update bug in JOIN command reply. Do
122 not directly upgrade the ID but call the function
123 silc_idlist_replace_channel_id if the ID was changed.
124 Affected file silcd/command_reply.c.
126 * Fixed memory leaks from command calling if it would fail.
127 Affected file silcd/command.c.
129 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
131 * Applied patches from cras:
133 Memory leak fixes around libaries, irssi window resize fix,
134 new silclist.h and silcdlist.h, all extern inline changed to
137 * Removed dotconf from lib/dotconf, not needed anymore.
139 * Removed TRQ from lib/trq, not needed anymore.
141 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
142 with server connections. Later this will be configurable
143 in config file after new config file is done. Affected file
146 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
148 * Fixed a crash in server related to channel announcements.
149 Affected file silcd/server.c.
151 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
153 * Fixed memory leaks in silc_server_create_new_channel*
154 functions. Affected file silcd/server.c.
156 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
157 which ID was changed. This way the router will send the
158 user list for the channel again, and server won't be in
159 desync in some rare circumstances. Affected file is
160 silcd/packet_receive.c.
162 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
164 * Check for NULL socket pointer in the function
165 silc_server_packet_send_to_channel_real. Affected file
168 * Fixed the BAN notify handling to correctly remove ban
169 list. Affected file silcd/packet_receive.c.
171 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
173 * Fixed some header addition to Toolkit distribution in
174 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
176 * Added lib/silcclient/client_ops_example.h as an template
177 file for application programmers to quickly start using
178 the SilcClientOperation functions in their application.
179 Updated the lib/silcclient/README as well to tell about this
180 nice file made available.
182 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
184 * Call silc_server_remove_from_channels when removing client
185 entry when NO_SUCH_CLIENT_ID was received. Affected file
186 is silcd/command_reply.c.
188 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
190 * Added server & router operator statistics updating. Affected
191 file silcd/packet_receive.c and silcd/command.c.
193 * Fixed the SERVER_SIGNOFF notify handling on normal server
194 not to save the history information for clients. Same was
195 fixed earlier in remove_clients_by_server function, but not
196 here. Affected file silcd/packet_receive.c.
198 * Raised the default connection-retry count from 4 to 7 in
199 server. Affected file silcd/server.h.
201 * Cancel any possible reconnect timeouts when we start the
202 key exchange. Affected file silcd/server.c.
204 * Do not reconnect on connection failure when SCONNECT was
205 given. Affected files silcd/server.[ch].
207 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
209 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
211 * Fixed the NICK command to always give the unformatted
212 nickname to the one giving the NICK command. If unformatted
213 nickname is cached already it will be formatted and the
214 local entry will always get the unformatted nickname.
215 Affected file lib/silcclient/idlist.c.
217 * Fixed some double frees from client library commands.
218 Affected file is lib/silcclient/command.c.
220 * Fixed CUMODE command in server to assure that no one can
221 change founder's mode than the founder itself, there was a
222 little bug. Affected file silcd/command.c.
224 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
226 * Removed the SilcClientCommandDestructor from the client
227 libary, it is not needed anymore. Affected files are
228 lib/silcclient/silcapi.h, command[_reply].[ch],
229 client_notify, idlist.c.
231 * Fixed GETKEY command to first resolve client, and then
232 resolve the server only if the client was not found, instead
233 of resolving both at the same time. Affected file is
234 lib/silcclient/command.c.
236 * Added silc_client_start_key_exchange_cb and lookup the
237 remote hostname and IP address before starting the key
238 exchange with server. The affected file is
239 lib/silcclient/client.c.
241 * The server's public key is now saved using the IP address
242 of the server and not the servername for the filename.
243 The hostname public key filename is checked as an fall back
244 method if the IP address based filename is not found.
246 Fixed the GETKEY command to save the fetched server key
249 Print the remote server's hostname now when new key is
250 received during connection process. Affected file is
251 irssi/src/silc/core/client_ops.c.
253 * Return always our own public key to the client if it asks
254 for it with GETKEY command. Affected file silcd/command.c.
256 * Removed the use_auto_addr variable from default config
257 file since it was in wrong section. Affected file is
260 * Fixed TOPIC_CHANGE notification to not route it when it
261 was sent using silc_server_send_notify_to_channel function.
262 Affected file silcd/command.c.
264 * Fixed silc_server_send_notify_kicked to send the kicker's
265 Client ID also, it was missing. Affected files are
266 silcd/command.c, silcd/packet_send.[ch].
268 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
270 * Do not save client history information in SERVER_SIGNOFF.
271 Fixes the bug in normal server that it does not detect
272 the client becoming valid after the server becomes back
273 online. Affected file silcd/server_util.c.
275 * Added `sock_error' field into the SilcSocketConnection
276 context. When error occurs during socket operation (read
277 or write) the error is saved. Added also new function
278 silc_socket_get_error to return human readable socket error
279 message. Affected files are lib/silcutil/silcsockconn.[ch],
280 lib/silcutil/unix/silcunixsockconn.c, and
281 lib/silcutil/win32/silcwin32sockconn.c.
283 * The server now prints the socket error message in the
284 signoff for client. Affected file silcd/server.c.
286 * Fixed the `created' channel information sending from router
287 to server in JOIN command. Checks now whether the channel
288 really was created or not and set it according that.
290 Fixed the JOIN command to use the client entry's current
291 ID during the joining procedure instead of the one it sent
292 in the command (it is checked though), since it can change
293 between the packet processing and command processing, and
294 would just case unnecessary pain in the client end. Affected
295 file silcd/command.c.
297 * Fixed a channel key payload sending to use correct channel
298 ID when the server was forced to change the channel's ID by
299 router. Router sent the key payload with the old Channel ID.
300 Affected file silcd/packet_receive.c.
302 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
304 * Call silc_server_save_channel_key only if the key payload
305 was provided in the JOIN command's command reply. Affected
306 file silcd/command_reply.c.
308 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
310 * Fixed silc_mp_sizeinbase to return the value correctly with
311 MPI. Affected file lib/silcmath/mp_mpi.c.
313 * Fixed the stop_server signal to correctly stop the scheduler
314 and gracefully stop the server when SIGTERM or SIGINT signals
315 are received. Affected file silcd/silcd.c.
317 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
319 * Simple handling of TERM and HUP signals. Also added some log
320 flushing call around. Affected file is
323 * Fixed small bugs in silclog.c. Now buffering output will take
324 effect after 10 seconds since startup: This will ensure that
325 no important startup messages are lost. Also output redirection
326 will preserve original format ([Date] [Type] message).
327 Affected file is lib/silcutil/silclog.c.
329 * Added two options to the config file, in the logging section:
330 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
331 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
333 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
335 * Do not print the warning about log files not being initialized
336 more than once to avoid excess logging. Affected file is
337 lib/silcutil/silclog.c.
339 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
340 the SIM copying in make install in Makefile.am.pre.
342 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
344 * Rewritten silclog APIs. Globally interesting changes follows:
345 silc_log_set_files() changed to silc_log_set_file().
346 silc_log_set_callbacks() changed to silc_log_set_callback().
347 ROBOdoc documented silclog header file.
348 SilcLogCb now returns bool to wether inihibit the default
349 handler or not (to keep the old behaviour return always TRUE).
350 The new APIs should also fix the problem of the
351 silcd_error.log file that was written in the current directory.
354 Log files streams will remain opened after silc_log_set_file()
355 call, means less CPU usage notably on high traffic servers.
356 File streams are now full buffered, and flushed to the disk
357 every 5 minutes, lesses HD activity and CPU usage.
358 Messages can be redirected, allowing admins to configure
359 one single logfile for all server messages.
360 the silc_log_quick global variable to activate fast-logging.
361 Affected files lib/silcutil/silclog.[ch]
363 * Changed some code to conform new silclog APIs. Affected
364 files are doc/example_silcd.conf.in, silcd/server.c
365 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
368 * Fixed a memory leak that could occur in some situations.
369 Affected file silcd/serverconfig.c.
371 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
373 * Added the silc_client_del_client to remove the client from
374 all channels as well. Affected file lib/silcclient/idlist.c.
376 * Fixed the client library to correctly remove the client
377 from all channels when the client entry is being destroyed.
378 Affected file lib/silcclient/client_notify.c, command.c.
380 * Added auto-nicking support to the client library. If the
381 applicatio now sets client->nickname it will be sent to the
382 server after connecting by the library. This way for example
383 SILCNICK (or IRCNICK) environment variables will have effect
384 and always change the nickname automatically to whatever
385 it is wanted. Affected file lib/silcclient/client.[ch].
387 * Renamed silc_server_command_bad_chars to the
388 silc_server_name_bad_chars and moved it to the
389 silcd/server_util.[ch]. Added also new function
390 silc_server_name_modify_bad to return nickname that
391 includes bad characters as new nickname without those
392 bad characters. This check and modify is now used in
393 silc_server_new_client when the username is initially set
394 as nickname, so it must be checked to be valid nickname.
395 Affected file silcd/packet_receive.c.
397 * The nickname length is now taken from the packet for real
398 and not trusted to strlen() since it clearly can return
399 wrong length for nickname including bad characters. This
400 also applies to channel names. Affected file silcd/command.c.
402 * Removed the lib/silcsilm/modules directory. Modules are now
403 compiled into the lib/silcsim. Fixed the copying of the
404 modules to follow symbolic links in Makefile.am.pre.
406 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
408 * Fixed silc_string_regexify list creation. Fixes bugs with
409 BAN and INVITE commands in server. The affected file is
410 lib/silcutil/unix/silcunixutil.c.
412 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
414 * Removed the command destructor entirely from the server's
415 command and command reply routines. It is not needed, and
416 its usage was buggy and caused crashes. Affected files are
417 silcd/command[_reply].[ch].
419 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
421 * Cancel protocol and NULL sock->protocol if timeout
422 occurred during protocol. Affected file silcd/server.c.
424 * Cancel protocol timeouts always before calling the final
425 callback, to assure that after final callback is called
426 no other state will be called for the protocol anymore.
427 Affected file silcd/protocol.c.
429 * Print error log if incoming connection configuration could
430 not be found. Affected file silcd/server.c.
432 * Fixed JOIN command to correctly save the founder mode
433 to the client on normal SILC server, when the channel
434 was created by the router. Affected file silcd/command.c.
436 * Fixed LIST command (hopefully) to send correct reply
437 packets. Affected file silcd/command.c.
439 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
441 * The silc_packet_receive_process now returns FALSE if the
442 read data was invalid packet, and TRUE if it was ok.
444 The server now checks that if unauthenticated connection
445 sends data and its processing fails the server will close
446 the connection since it could be a malicious flooder.
448 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
450 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
452 * Make sure the warning about error opening a log file is
453 printed only once and not everytime it fails (produces
454 too much useless log). Affected file lib/silcutil/silclog.c.
456 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
458 * Made the silc_server_daemonise() function more readable.
459 Affected file silcd/server.c.
461 * Pid file is now optional, the user may comment it out from
462 the config file. Removed define SILC_SERVER_PID_FILE, we
463 don't need a default any longer. Affected file
464 configure.in.pre, lib/Makefile.am.pre.
466 * Make some use of the pid file. The server now dies at startup
467 if it detects a valid pid file on his path. The server would
468 die anyway in this circumstance, because of the bind() failure.
469 Affected file silcd/silcd.c.
471 * No longer compiling lib/dotconf.
473 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
475 * Fixed JOIN command parsing not to crash. Affected file
476 lib/silcclient/command.c.
478 * Fied the NICK_CHANGE notify to add the new client entry
479 even it is resolved. This removes an <[unknown]> nick
480 thingy bug in the client. Affected file is
481 lib/silcclient/client_notify.c.
483 * Do not try to allocate 0 bytes (efence does not like it)
484 in lib/silccore/silccomand.c when encoding payload.
486 * Do not take IRCNICK as nickname in Irssi SILC client since
487 it is not possible to set nickname before hand connecting
488 the server (TODO has an entry about adding auto-nicking
491 * Changed the silc_server_command_pending to check whether
492 there already exists an pending entry with the specified
493 command, command identifier and pending callback. This is
494 to fix IDENTIFY and WHOIS related crashes that may register
495 multiple pending commands with same identifier. Affected
496 file silcd/command.c.
498 * Fixed the server to reconnect to the router even if it
499 was already reconnecting and EOF was received. This to
500 fix a possibility that the server wouldn't ever try to
501 auto-reconnect to the router. Affected file silcd/server.c.
503 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
505 * Fixed the server's password authentication to use the
506 length of the locally saved password, and not the one
507 sent in the packet. Affected file silcd/protocol.c.
509 * Fixed same password authentication problem in the
510 Authentication Payload handling routines in
511 lib/silccore/silcauth.c.
513 * Yet another password authentication problem fixed with
514 channel password handling in silcd/command.c.
516 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
518 * If first character of string in silc_parse_userfqdn is '@'
519 then do not parse it. Affected file is
520 lib/silcutil/silcutil.c.
522 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
524 * Fixed minor bug in IDENTIFY command reply sending, which
525 caused various weird problems during JOIN when it was
526 resolving names for users. Affected file silcd/command.c.
528 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
530 * Fixed the IDENTIFY command reply sending to chech better valid
531 clients. It was possible to send incomplete list of replies.
532 Affected file silcd/command.c.
534 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
536 * Added silc_client_command[s]_[un]register functions now to
537 dynamically register the commands in client library. Removed
538 the static table of commands. This allows the client library
539 to call commands without causing the application to know about
540 what commands library has called.
542 Removed the INFO command reply kludge to detect when the command
543 was called by library. Now library use its own command reply
544 function for INFO command.
546 Added function silc_client_command_call to call a command.
547 Application can use it to call command, not access the structure
550 Now all commands that are sent by the client library (not
551 explicitly sent by application) use own command reply functions.
553 Affected files around lib/silcclient/ and in
554 irssi/src/silc/core/.
556 * Fixed the WHOIS command reply sending to chech better valid
557 clients. It was possible to send incomplete list of replies.
559 Fixed the WHOIS and IDENTIFY to send the request to router
560 if normal server did not do it and did not find any results.
562 Affected file silcd/command.c.
564 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
566 * Moved the internal data from SilcClient context into its
567 own file, not accesible to application. Affected files
568 lib/silcclient/client.h and lib/silcclient/client_internal.h,
569 and other files in client library.
571 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
573 * Added doc/examples installation target in Makefile.am.pre.
576 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
578 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
579 commands the found client entry will be removed from the
580 cache, after notifying application about the error. Affected
581 file lib/silcclient/command_reply.c.
583 * Changed the /MSG to check for exact nickname user gave, and
584 not let `nick' match `nick@host' if it is only one found. Now,
585 user must type the exact nickname (like nick@host2) even if
586 there are no more than one same nicks found. This is to avoid
587 a possibility of sending nickname to wrong nickname since
588 `nick' could match `nick@host'. Affected file is
589 irssi/src/core/silc-servers.c.
591 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
593 * Do not print "you are now server operator" or similar when
594 giving /away command. Affected files are
595 irssi/src/silc/core/client_ops.c, silc-servers.h.
597 * Made the silc_server_command_pending_error_check to send
598 the same command reply payload it received back to the
599 original sender of the command. This way all arguments
600 that was received by the server will be received by the
601 client too. Affected file silcd/command.c.
603 * Added the silc_idcache_add to return the created cache entry
604 to a pointer. Affected file lib/silccore/silcidcache.[ch].
606 * Add global clients to expire if they are not on any channel.
607 This is because normal server will never know if they signoff
608 if they are not on any channel. The cache expiry will take
609 case of these entries. This is done by normal servers only.
610 The affected files are silcd/command_reply.c,
611 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
613 * If server receives invalid ID notification for WHOIS or
614 IDENTIFY and the ID exists in the lists, it is removed.
615 Affected file silcd/command_reply.c.
617 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
618 in client then client entry that it matches is searched and
619 the nickname is printed on the screen for user. Affected
620 file irssi/src/silc/core/client_ops.c.
622 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
624 * Use cache entry expire time in the LIST command reply to
625 purge old entries from the cache after the LIST command
626 reply has been received. This way we don't have non-existent
627 entries in the cache for too long. Affected file is
628 silcd/command_reply.c.
630 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
632 * If we are normal server, and we've not resolved client info
633 in WHOIS or IDENTIFY from router, and it is global client,
634 we'll check whether it is on some channel. If it is not
635 then we cannot be sure about its validity and will resolve it
636 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
637 file silcd/command.c.
639 * Search channel by name (if possible) rather than by ID
640 in IDENTIFY command's command reply. Affected file is
641 silcd/command_reply.c.
643 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
645 * Distribute to the channel passphrase in CMODE_CHANGE notify.
646 Updated specs and implemented it. Affected file silcd/command.c,
647 silcd/packet_send.c and silcd/packet_receive.c.
649 * Implemented the <founder auth> payload handling in the JOIN
650 command. If provided all conditions for channel joining
651 except requirement to provide correct passphrase can be
652 overrided by the channel founder. Updated the protocol specs.
653 Affected file silcd/command.c.
655 Added support for founder auth in JOIN command in client
656 library. Fixed the parsing of the JOIN command now to support
657 all options as they should be. The affected file is
658 lib/silcclient/command.c.
660 * Optimized the WHOIS and IDENTIFY commands to send the request
661 to router only if it includes nicknames or other names. If
662 they include only IDs then check the local cache first before
663 routing. Affected file is silcd/command.c.
665 * Added channels topic announcements. Affected file is
666 silcd/packet_receive.c and silcd/server.c.
668 * Fixed the silc_server_send_notify_topic_set to really destine
669 the packet to channel. Affected file silcd/packet_send.c.
671 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
672 library. Affected file lib/silcclient/client_notify.c.
674 * Added UMODE announcements. Affected file silcd/server.c.
676 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
678 * Memory leak fixes in:
680 lib/silcutil/silcsockconn.c
681 lib/silcske/silcske.c
684 lib/silccrypt/silcpkcs.c
685 lib/silccore/silccommand.c
686 lib/silccore/silcidcache.c
691 * ROBOdoc documented the lib/silcske/groups.h file and a
692 bit changed the interface for better.
694 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
696 * Update the client entry context in the ID cache after
697 nick change. Affected file lib/silcclient/command.c.
698 Fixes the CUMODE command when regaining founder privileges,
699 and a little WHOIS problem.
701 * Fixed silc_net_gethostbyname to correctly call the
702 inet_ntop. Affected file lib/silcutil/silcnet.c.
704 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
706 * Added IPv6 support checking to the configure.in.pre, added
707 also --enable-ipv6 option to override the check. Affected
708 file configure.in.pre.
710 * The silc_thread_create now calls the start function
711 directly if threads support is not compiled in. Removes
712 ugly #ifdef's from generic code. Affected files are
713 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
715 * Added silc_net_gethostby[name/addr]_async to asynchronously
716 resolve. Affected files are lib/silcutil/silcnet.[ch].
718 * Added support for rendering IPv6 based server, client and
719 channel IDs. Affected file lib/silcutil/silcutil.c.
721 * Added support for creating IPv6 based server IDs. Affected
722 file is silcd/serverid.c.
724 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
726 * Added silc_net_gethostby[addr/name] into the
727 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
728 routines. Added silc_net_is_ip[4/6]. Affected file is
729 lib/silcutil/unix/silcunixnet.c. All routines that take
730 address as argument now supports both IPv4 and IPv6 addresses.
732 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
734 * Fixed LIST command reply sending in server. Affected file
737 * Server now sends the kicker's client ID in the KICK notify
738 to the kicked client. Affected file silcd/command.c.
740 * The client library now parses the kickers client ID and
741 UI displays it. Affected files lib/silcclient/client_notify.c
742 and irssi/src/silc/core/silc-channels.c, module-formats.c.
744 * Made all payload parsing function prototypes consistent.
745 They all take now const unsigned char * and uint32 pair as
746 the payload data instead of SilcBuffer. Changes all around
747 the source tree. Other unsigned char* -> const unsigned char*
748 changes around the tree as well.
750 * Optimized SFTP client and server packet sending not to
751 allocate new buffer for each packet but to recycle the
752 first allocated buffer. Affected files are
753 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
755 * Optimized the SFTP client to use SilcList instead of
756 SilcDList for requests, because it is faster. Affected file
757 is lib/silcsftp/sftp_client.c.
759 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
760 into lib/silccore/silcid.[ch].
762 Renamed silcpayload.[ch] into silcargument.[ch].
764 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
766 * If client entry is deleted with active key agreement
767 session, abort the session.
769 The silc_client_abort_key_agreement now calls the completion
770 callback with new SILC_KEY_AGREEMENT_ABORTED status.
772 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
775 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
777 * Don't use __restrict in older GCC's. Affected file is
778 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
780 * silc_net_localhost now attempts to reverse lookup the
781 IP/hostname. Affected file lib/silcutil/silcnet.c.
783 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
784 command. It can be used to gain founder privileges at
785 the same time when joining the channel.
787 Defined that the SILC_NOTIFY_TYPE_KICKED send the
788 kicker's client ID as well. Updated protocol specs.
790 Defined that the server must send SILC_COMMAND_IDENTIFY
791 command reply with error status to client who sent
792 private message with invalid client ID.
794 Updated the protocol specification.
796 * Added silc_server_send_command_reply to send any
797 command reply. Affected file silcd/packet_send.[ch].
799 * Added silc_id_payload_encode_data to encode ID payload
800 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
802 * The server now send IDENTIFY command reply with error
803 status if client ID in private message is invalid. Affected
804 file silcd/packet_receive.c.
806 * Save the server key file with server's IP address in
807 the filename instead of hostname. The affected file is
808 irssi/src/silc/core/client_ops.c.
810 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
812 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
815 * Added libtool support for compiling shared objects in
816 lib/silcsim. Affected file configure.in.pre and
817 lib/silcsim/Makefile.am. Original patch by cras.
819 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
821 * Pid file configuration, and server's config file fixes
822 patch by toma. Updated CREDITS file.
824 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
826 * Fixed silc_client_channel_message to not try to decrypt
827 the message twice if it resolved the destination client
828 information. This could cause of dropping one channel
829 message. Affected file lib/silcclient/client_channel.c.
831 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
833 * Added silc_client_run_one into lib/silcclient/silcapi.h and
834 lib/silcclient/client.c. This function is used when the SILC
835 Client is run under some other scheduler, or event loop or
836 main loop. On GUI applications, for example this may be
837 desired to used to run the client under the GUI application's
838 main loop. Typically the GUI application would register an
839 idle task that calls this function multiple times in a second
840 to quickly process the SILC specific data.
842 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
844 * Fixed silc_server_drop() for dropping the supplementary
845 groups as well, this could cause a security hole on some
848 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
850 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
853 * Write PID file after dropping privileges. Added -F option
854 to run server on foreground. A patch by debolaz.
855 Affected files silcd/server.c, silcd/silcd.c.
857 * Fixed MOTD to return the MOTD file server name. Affected
858 file silcd/command.c.
860 * Added INFO command reply handling to the Irssi SILC Client.
861 Affected file irssi/src/silc/core/client_ops.c.
863 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
865 * Fixed the silc_idcache_list_* routines to really support
866 the dynamic list. Fixes a crash. Affected file is
867 lib/silccore/silcidcache.c.
869 * Fixed the LIST command reply to really call LIST command's
870 pending callbacks. Affected file silcd/command_reply.c.
872 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
874 * Update conn->local_entry->nickname after giving NICK
875 command. Affected file lib/silcclient/command.c.
877 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
879 * Added the [pid] option to the silcd configuration file
881 Affected files: serverconfig.[ch] and silcd.c
883 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
885 * Save fingerprint in WHOIS command reply in server.
886 Affected file silcd/command_reply.c.
888 * Fixed NICK commands pending callback registration.
889 Affected file lib/silcclient/command.c.
891 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
893 * Use ++server->cmd_ident when sending commands in server,
894 instead of random number. Affected file silcd/command.c.
896 * Fixed GETKEY command reply to call actually GETKEY pending
897 command callbacks. Affected file silcd/command_reply.c.
899 * A bit stricter check for nicknames. Check for same nickname
900 in NICK command also. Affected file silcd/command.c.
902 * Do not call INFO command everytime client ID changes, only
903 during first connecting. Affected file lib/silcclient/client.c.
905 * Set the new nickname only after successful command reply for
906 NICK command is returned by server. Affected file
907 lib/silcclient/command.c.
909 * Remove nicknames from nicklist during server_signoff notify.
910 Should fix /NAMES bit more. The affected file is
911 irssi/src/silc/core/silc-channels.c.
913 * Added `fingerprint' field to the SilcIDListData in the
914 silcd/idlist.h to hold the fingerprint of the client's
917 Send the fingerprint of the client's public key in WHOIS
920 Affected files silcd/command.c, and silcd/idlist.[ch].
922 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
923 create fingerprint from given data.
925 * Show the fingerprint of the client's public key in WHOIS.
926 Affected files irssi/src/module-formats.[ch] and
927 irssi/src/silc/core/client_ops.c.
929 * Format the multiple same nicknames also during JOIN and
930 NICK_CHANGE notifys. Affected file is
931 lib/silcclient/client_notify.c.
933 * Do not print error on screen for invalid private message
934 payload since it can come if someone is sending private
935 messages with wrong key. Affected file
936 lib/silccore/silcprivate.c.
938 * Fixed multiple concurrent /PING crash. Affected file
939 lib/silcclient/command.c.
941 * Changed the wrong ID encoding. All IP addresses must be
942 in MSB first order in encoded format. They were encoded
943 wrong and was in LSB format. Affected files are
944 silcd/serverid.c, lib/silcutil/silcutil.c.
946 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
948 * Call the `connect' client operation through the scheduler
949 in case of error. Affected file lib/silcclient/client.c.
951 * Call the `failure' client operation even if the error
952 occurred locally during a protocol. Affected file is
953 lib/silcclient/protocol.c.
955 * Added support of sending LIST command to router from normal
956 server. This way normal server can get list of all channels
957 in the network too. Fixed the channel list sending in the
958 server too. Affected files are silcd/command.c, and
959 silcd/command_reply.[ch].
961 * Added silc_server_update_channels_by_server and
962 silc_server_remove_channels_by_server. They are used during
963 disconnection of primary router and in backup router protocol.
964 Affected file silcd/server_util.[ch], silcd/server.c and
965 silcd/server_backup.c.
967 * Fixed channel adding to global list in IDENTIFY command
968 reply in server. Affected file silcd/command_reply.c.
970 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
972 * If the incoming packet type is REKEY or REKEY_DONE process
973 that packet always synchronously. Fixes yet another MAC
974 failed error on slow (dialup) connections. Affected file
975 lib/silcclient/client.c and silcd/server.c.
977 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
979 * Call check_version SKE callback for initiator too. Affected
980 file lib/silcske/silcske.c.
982 * Implemented fix for security hole found in the SKE that was
983 fixed in the specification few days back; the initiator's
984 public key is now added to the HASH value computation.
985 Added backwards support for the old way of doing it too, for
986 old clients and old servers. Affected file is
987 lib/silcske/silcske.c.
989 * Enabled mutual authentication by default in SKE. If initiator
990 is not providing mutual authentication the responder will
991 force it. This will provide the proof of posession of the
992 private key for responder. The affected files are
993 lib/silcclient/protocol.c and silcd/protocol.c.
995 * Do not cache anymore the server's public key during SKE.
996 We do mutual authentication so the proof of posession of
997 private key is done, and if the server is authenticated in
998 conn auth protocol with public key we must have the public
999 key already. Affected file silcd/protocol.c.
1001 * Added new global debug variable: silc_debug_hexdump. If
1002 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1003 file lib/silcutil/silclog.[ch].
1005 * Fixed compilation warning due to char * -> const char *.
1006 Affected files lib/silcutil/silcnet.h, and
1007 lib/silccore/silcauth.[ch].
1009 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1011 * Fixed CMODE command when new channel key was created. If
1012 the creation failed the old key was removed. Next time giving
1013 same command would crash the server since the old key was
1014 freed already. Affected file silcd/command.c.
1016 * Fixed the silc_server_announce_get_channels to not crash
1017 on reconnect. Affected file silcd/server.c.
1019 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1021 * Added silc_log_set_debug_string function to set a regex
1022 string to match for debug output. Only the function names,
1023 or filenames matching the given debug string is actually
1024 printed. This way it is possible to filter out those debug
1025 strings that user is not interested in.
1027 Fixed a bug in silc_string_regexify.
1029 Affected files lib/silcutil/silclog.[ch], and
1030 lib/silcutil/unix/silcunixutil.c.
1032 * Changed the -d options in both server and Irssi SILC client
1033 to take the debug string as argument. Affected files
1034 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1036 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1038 * Added silc_hash_babbleprint to create a Bubble Babble
1039 Encoded fingerprint. The encoding is developed by Antti
1040 Huima (draft-huima-babble-01.txt), and it creates human
1041 readable strings out of binary data. Affected file
1042 lib/silccrypt/silchash.[ch].
1044 * Print the babble print now in addition of fingerprint as well
1045 in Irssi SILC client. Affected files are
1046 irssi/src/fe-common/silc/module-formats.[ch],
1047 irssi/src/fe-common/silc/core/client_ops.c.
1049 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1051 * Fixed a security problem found in SKE. The initiator's
1052 public key too is now added to the HASH hash value creation
1053 which is signed by the responder to create the SIGN value.
1054 This will prevent anyone in the middle to lie to the responder
1055 about the initiator's public key. If this is done now, the
1056 man in the middle will get caught. Updated the protocol
1059 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1061 * Better installation directory handling. Configure module
1062 paths and other paths automatically to example_silc* files
1063 in doc/. A patch by toma.
1065 * Fixed compiler warning from MPI library, and from SILC RNG.
1068 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1069 It can be configured with ./configure. A patch by toma.
1071 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1073 * Find correct make to use in prepare-clean. A patch by
1074 toma. Affected file prepare-clean.
1076 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1078 * Added irssi variables use_auto_addr, auto_bind_ip,
1079 auto_bind_port and auto_public_ip.
1081 * Changed the interface for silc_client_send_key_agreement
1082 in lib/silcclient/silcapi.h
1086 irssi/src/silc/core/silc-core.c
1088 lib/silcclient/silcapi.h
1089 irssi/src/silc/core/silc-channels.c
1090 lib/silcclient/client_keyagr.c
1093 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1095 * Added silc_pkcs_public_key_compare to compare two
1096 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1098 * Check that the client who set the founder mode on the
1099 channel is the same client that is giving the founder
1100 mode to itself. It is done by comparing the saved public
1101 key (it is saved even in the authentication is passphrase).
1102 Affected file silcd/command.c.
1104 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1106 * Do not process packet for disconnected socket connection.
1107 Affected file lib/silccore/silcpacket.c.
1109 * Process the DISCONNECT packet through scheduler in the
1110 client library. Affected file lib/silcclient/client.c.
1112 * Fixed the silc_client_packet_parse to not to increase
1113 the packet sequence number if the conn->sock and the
1114 current socket connection is not same. This can happen
1115 for example during key agreement when the conn includes
1116 multiple socket connections (listeners). Affected file
1117 lib/silcclient/client.c.
1119 * The sender of the file transfer request now provides also
1120 the pointer (listener) for the key exchange protocol. If
1121 the listener cannot be created then it sends empty key
1122 agreement and lets the receiver provide the listener.
1124 Added `local_ip' and `local_port' arguments to the
1125 silc_client_file_send. If they are provided they are used,
1126 if not then it will attempt to find local IP address, if
1127 not found or bind fails then the remote client will provide
1130 Affected files are lib/silcclient/client_ftp.c and
1131 lib/silcclient/silcapi.h.
1133 * Extended the FILE SEND command to support defining the
1134 local IP and port for key exchange listener. They are

1139 * Defined to WHOIS command reply the sending of fingerprint
1140 of the client's public key (if the proof of posession of the
1141 corresponding private key is verified by the server).
1142 Updated to the protocol specification.
1144 * Added support of receiving the client's public key's
1145 fingerprint in command reply in client library. Affected
1146 file is lib/silcclient/command_reply.c, and
1147 lib/silcclient/idlist.[ch].

1206 preserve the WHOWAS info for the client. Affected file
1207 silcd/server_util.c.
1209 * Fixed SERVER_SIGNOFF notify handling in the server. The
1210 server is now able to process incoming SERVER_SIGNOFF notify
1211 for a server that it doesn't even know about. It will remove
1212 the clients provided in the notify. Affected file
1213 silcd/packet_receive.c.
1215 * Check for partial packet in data queue after every packet that
1216 was found from the queue. Return and wait for more data if
1217 there is partial data in queue. Affected file is
1218 lib/silccore/silcpacket.c.
1220 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1235 irssi/src/fe-common/silc/module-formats.[ch].
1237 * Wrote a help file for FILE command.
1239 * Added silc_rng_global_get_byte_fast to get not-so-secure
1240 random data as fast as possible. Random data is read from
1241 /dev/urandom if available and from the SILC RNG if not
1242 available. It is used in padding generation. Affected file
1243 lib/silccrypt/silcrng.[ch].
1245 * All packets in client library are now processed synchronously.
1246 Optimized packet processing a lot. Affected file
1247 lib/silcclient/client.c.

1258 * Assure that silc_client_notify_by_server_resolve does not
1259 resolve the client information multiple times. If it cannot
1260 be found by the first it cannot be found at all. Affected
1261 file lib/silcclient/client_notify.c.
1263 * Fixed WHOWAS command reply calling. Affected file
1264 lib/silcclient/command_reply.c.
1266 * Removed all references to silc_idlist_get_client from the
1267 Irssi SILC client since that call is internal call used by
1268 the library. The Irssi SILC client will use now client
1269 retrieval functions found in silcapi.h.
1271 * Fixed a bug in resolving nickname info before sending
1272 private message. It used freed memory. Affected file
1273 irssi/src/silc/core/silc-servers.c.
1275 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1277 * Assure my_channels statistics cannot go negative in server.
1278 Affected files silcd/server.c, silcd/server_util.c.

1294 * Added silc_net_localip to return local host's IP address.
1295 Affected file lib/silcutil/silcnet.[ch].
1297 * If key exchange or rekey protocol is active for a connection
1298 parse all packets syncronously since there might be packets
1299 in packet queue that we are not able to process without first
1300 processing packets before them. Affected file silcd/server,
1301 lib/silcclient/client.c.
1303 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1304 whether library should continue processing the packet.
1305 Affected file lib/silccore/silcpacket.h.

1351 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1352 is incomplete and is being resolved, it won't be resolved
1355 Make sure also that USERS command reply does not resolve
1356 twice information. Affected file is
1357 lib/silcclient/command_reply.c.
1359 Make sure that silc_client_get_clients_by_list does not
1360 resolve twice same information.
1362 * Check for valid client->id in the silc_server_free_client_data.
1363 Affected file silcd/server.c.
1365 * Fixed /GETKEY nick@server not to crash if the server entry
1366 is not found. Affected file lib/silcclient/command.c.
1368 * Fixed the silc_server_check_cmode_rights to check the
1369 requested modes correctly. Affected file silcd/command.c.
1371 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1373 * Better checks for non-printable chars in nick added.
1374 Affected file silcd/command.c.
1376 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1378 * Call the silc_server_udpate_servers_by_server in the
1379 primary router that comes back online in the backup resuming
1380 protocol. Otherwise it routes packets wrong. Affected file
1381 silcd/server_util.[ch], silcd/server_backup.c.
1383 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1385 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1386 lib/silcutil/silcbuffmt.[ch].
1388 * Redefined the SILC packet header to include the padding
1389 length. Affected file lib/silccore/silcpacket.[ch].
1391 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1392 length for maximum padding up to 128 bytes). Affected
1393 file lib/silccore/silcpacket.h.
1395 * Removed all backwards support for old 0.5.x MAC thingies.
1396 The SILC packet header change makes it impossible to be
1397 backwards compatible.
1399 * Send the ENDING packet with timeout in the backup resuming
1400 protocol. This is to assure that all routers has connected
1401 to the primary router. Affected file silcd/server_backup.c.
1403 * Changed the RNG to take the first IV from random data. It
1404 used to take it from zero actually. Changed the RNG also
1405 to use /dev/urandom during session. /dev/random is used
1406 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1408 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1410 * Changed the SILC packet header to have the first two bytes
1411 (the packet length) encrypted. Affected files aroung the
1412 code tree, lib/silccore/silcpacket.[ch]. Removed the
1413 SilcPacketCheckDecrypt callback. It is not needed anymore
1414 since the silc_packet_receive_process will determine now
1415 whether the packet is normal or special.
1417 * Implemented the unidirectional MAC keys. Affected files
1418 lib/silcske/silcske.c, silcd/protocol.c and
1419 lib/silcclient/protocol.c.
1421 * Implemented the packet sequence number to the MAC computation.
1422 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1423 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1424 lib/silcclient/protocol.c.
1426 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1428 * Allow backup router to announce servers. All servers
1429 announced by backup router are added to the global list
1430 automatically. Update hte server's socket to our primary
1431 router also when backup router announces a server.
1432 Affected file silcd/packet_receive.c.
1434 * Do not update the client->router in the function
1435 silc_server_udpate_clients_by_server if the client is on
1436 global list. We might fail to find any specific server
1437 for locally connected clients and local cell clients. They
1438 should still use the `from' and not `to' as client->router.
1439 This fixes backup router resuming protocol. Affected file
1440 silcd/server_util.c.
1442 * Decrease channel statistics count only if the channel
1443 deletion worked. Affected files are silcd/server.c and
1444 silcd/server_util.c.
1446 * Added silc_server_update_servers_by_server to update origin
1447 of all server entries. Used during backup router protocol.
1448 Affected files silcd/server_util.[ch], silcd/server.c. and
1449 silcd/backup_router.c.
1451 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1452 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1453 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1454 lib/silccrypt/silchmac.c.
1456 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1458 * Assure that router cannot reroute the same channel message
1459 to the sender. Affected file silcd/packet_receive.c.
1461 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1463 * Made better checks that the channel message is not sent
1464 to the router it came from. Affected file is
1465 silcd/packet_send.c. Fixed memory leak too.
1467 * Announce informations for incoming router connection, but
1468 only after checking if it is replaced by backup router.
1469 Affected file silcd/packet_receive.c.
1471 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1473 * Fixed the backup resuming protocol to work in multiple
1474 router environment. Affected file silcd/server_backup.c.
1476 * Route packet only to one router in the function
1477 silc_server_packet_send_to_channel. Affected file is
1478 silcd/packet_send.c.
1480 * Fixed silc_server_send_notify_dest to set the broadcast
1481 flag. Fixed the silc_server_send_notify_topic to actually
1482 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1483 Affected file silcd/packet_send.c.
1485 * Changed the SFTP Filesystem interface. Changed the
1486 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1487 the filesystem operation function. The SilcSFTPFilesystem
1488 is now a context that is allocated by all filesystem allocation
1489 functions and it already includes the operations structure
1490 and filesystem specific context. It is given as argument
1491 now to the silc_sftp_server_start. This made the interface
1492 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1493 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1495 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1497 * Changed the backup router adding and getting interfaces
1498 in the server. The router that will be replaced by the
1499 specified backup router is now sent as argument. Affected
1500 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1503 * Added silc_net_addr2bin_ne to return the binary form of
1504 the IP address in network byte order. Affected files
1505 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1507 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1509 * Check for existing server ID in silc_server_new_server
1510 and in silc_server_connect_to_router_final and remove the
1511 old entry if it exists. Affected file silcd/packet_receive.c,
1514 * Send the channel message always to only one router, either
1515 in upstream or downstream. Affected file is
1516 silcd/packet_send.c.
1518 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1520 * Wrote the definition of the backup resuming protocol to the
1521 protocol specification.
1523 * Removed one redundant channel key generation from normal
1524 server during joining procedure. Removed one redundant
1525 channel key sending from server to router during joining
1526 procedure. Affected file silcd/command.c.
1528 * Made minor bugfixes to the backup router resuming protocol.
1529 Affected file silcd/server_backup.c, server.c.
1531 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1533 * Added --disable-asm configuration option. Affected files
1534 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1537 * Implemented the backup resuming protocol that is used to
1538 resume the primary router position in the cell after the
1539 primary router comes back online. Affected files
1540 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1541 and silcd/server_util.[ch].
1543 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1545 * Sleep two (2) seconds after sending QUIT command to server.
1546 Affected file lib/silcclient/command.c.
1548 * Assure that if outgoing data buffer is pending do not force
1549 send any data. Affected file silcd/packet_send.c.
1551 * Assure that if outgoing data buffer is pending do not force
1552 send any data. Affected file lib/silcclient/client.c.
1554 * Implemented the backup router support when the primary router
1555 goes down. The servers and routers can now use the backup
1556 router as new primary router without loosing connectivity.
1558 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1560 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1561 in the server to indicate disabled entry. All data read
1562 from the connection will be ignored and no data is sent
1563 for entry that is disabled. Affected files are
1564 silcd/idlist.h, silcd/server.c.
1566 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1568 * Created SFTP client and server test programs in the
1569 lib/silcsftp/tests directory.
1571 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1573 * Implemented memory filesystem (virtual filesystem) for
1574 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1577 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1579 * Implemented the SFTP (SSH File Transfer Protocol) to the
1580 lib/silcsftp. It includes SFTP client and SFTP server
1583 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1585 * Moved lib/silccore/silcprotocol.[ch] to the
1586 lib/silcutil library.
1588 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1589 take variable argument list pointer as argument. Affected
1590 file lib/silcutil/silcbuffmt.[ch].
1592 * Added silc_buffer_set function that is used to set data
1593 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1594 Affected file lib/silcutil/silcbuffer.h.
1596 * Changed various routines in the core library to use the new
1597 silc_buffer_set instead of allocating new buffer only for
1600 * Added 64-bit value formatting and unformatting support to the
1601 silc_buffer_[un]format routines. Affected file is
1602 lib/silcutil/silcbuffmt.[ch].
1604 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1605 to includes/bitmove.h.
1607 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1609 * Fixed channel user mode saving in client library. Affected
1610 file lib/silcclient/command[_reply].c.
1612 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1614 * Defined the file transfer to the SILC Protocol. Added
1615 new packet type SILC_PACKET_FTP and defined File Transfer
1616 Payload. The mandatory file transfer protocol is SFTP
1617 (SSH File Transfer Protocol). Affected file in addition
1618 of the internet draft is lib/silccore/silcpacket.h.
1620 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1621 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1622 is used as part of backup router protocol when the primary
1623 router of the cell is back online and wishes to resume
1624 the position as primary router.
1626 * Redefined the MAC generation keys in the protocol. The
1627 same key is not used anymore in both direction. Both
1628 direction will now use different keys for sending and
1629 receiving. This fixes a potential security flaw. This
1630 change causes incompatibilities in the protocol.
1632 * Redefined also the MAC computation from the packet.
1633 An packet sequence number is now added to the MAC
1634 computation. This prevents possible replay attacks against
1635 the protocol. This change too causes incompatibilities
1638 Added `sequence' field to the SilcPacketContext to hold
1639 the current sequence number for the packet.
1641 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1643 * Added `created' field to the SilcIDListData in the file
1644 silcd/idlist.h to indicate the time when the entry was
1647 * Added `created' field to the SilcChannelEntry too. Affected
1648 file silcd/idlist.h.
1650 * Added `creation_time' aguments to all the announcement functions
1651 in the server. If it is provided then only the entries that
1652 was created after the provided time frame are actually
1653 announced. Affected file silcd/server.[ch].
1655 * The protocol says that the Channel ID's IP address must be
1656 based on the router's IP address. Added check for this in
1657 the silc_server_new_channel when processing incoming New Channel
1658 Payload. Affected file silcd/packet_receive.c.
1660 * Print out the correct version with --version in SILC client.
1661 Affected file irssi/src/silc/core/silc-core.c.
1663 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1665 * Fixed WHOWAS command to check for completnes of the client
1666 entry always, not just when the command is coming from client.
1667 Affected file silcd/command.c.
1669 * Added new function silc_server_packet_queue_purge to purge the
1670 outgoing data queue to the network. After the function returns
1671 it is guaranteed that the outgoing packet queue is empty.
1672 Affected file silcd/packet_send.[ch].
1674 * Purge the outgoing packet queue in the rekey protocol's final
1675 callback to assure that all rekey packets go to the network
1676 before quitting the protocol. Affected file silcd/server.c.
1678 * Added silc_client_packet_queue_parse as similar function as
1679 in server to the client library. The affected file is
1680 lib/silcclient/client.c.
1682 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1684 * Splitted silcd/server.c and created silcd/server_util.[ch]
1685 for utility functions.
1687 * Added new socket flag SILC_SF_DISABLED to indicate that the
1688 connection is open but nothing can be sent to or received from
1689 the connection. Affected file lib/silcutil/silsockconn.[ch].
1690 The checking for disabled socket is checked in the low level
1691 silc_socket_write and silc_socket_read functions.
1693 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1695 * Allow only nicknames and channel names that fits into the
1696 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1698 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1700 * When processing JOIN command reply in server check that if
1701 the channel exists in our global list we'll move it the local
1702 list. Affected file silcd/command_reply.c.
1704 * Fixed the check whether client is joined on the channel already
1705 in JOIN command. Affected file lib/silcclient/command.c.
1707 * Fixed the JOIN command reply to check whether the channel
1708 already exists. Affected file lib/silcclient/command_reply.c.
1710 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1712 * Added silc_ske_status_string to map the SKE error numbers
1713 to readable strings. The affected files are
1714 lib/silcske/silcske[_status].[ch].
1716 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1718 * Do not show the private channels on the WHOIS channel list
1719 as it is not allowed by the protocol. The affected file is
1722 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1724 * Assure that the packet length digged from the actual packet
1725 is something sensible in the silc_packet_decrypt_rest_special
1726 in lib/silccrypt/silcpacket.c.
1728 * Free and NULL the allocated pointer in silc_hmac_alloc if
1729 the HMAC allocation fails. The affected file is
1730 lib/silccrypt/silchmac.c.
1732 * Print the selected security properties to the log files in
1733 the server. Affected file silcd/protocol.c.
1735 * Add SKE's reference counter even if calling the completion
1736 callback manually. Otherwise it goes negative, although it
1737 does not cause any problems. The affected file is
1738 lib/silcske/silcske.c.
1740 * Remove the client entry with short timeout after giving the
1741 KILL command. Affected file lib/silcclient/command.c.
1743 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1744 case all found clients are already disconnected (WHOWAS would
1745 found them) in the server. Affected file silcd/command.c.
1747 * Update the last_receive (time of last data received) to be
1748 updated only when received private or channel message so that
1749 the idle time showed in WHOIS makes more sense.
1751 * Added boolean field `valid' in to the SilcClientEntry in the
1752 client library to indicate whether the entry is valid or not.
1753 This fixes the nickname change bug on channel when changing
1754 the nickname to be same than the old (like nick to Nick) the
1755 nickname formatter doesn't set the new nick anymore to Nick@host.
1756 Affected file lib/silcclient/idlist.[ch].
1758 * Now actually fixed the nickname changing on disconnection.
1759 Added new function silc_change_nick to the Irssi SILC Client.
1760 Affected file irssi/src/silc/core/client_ops.c,
1761 irssi/src/silc/core/silc-nicklist.[ch].
1763 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1765 * Check that the public key exists in the GETKEY command before
1766 trying to encode it. Affected file silcd/command.c.
1768 * Print some notifications on received public keys with GETKEY
1769 command in the Irssi SILC Client. Affected files are
1770 irssi/src/fe-common/silc/module-formats.[ch],
1771 irssi/src/silc/core/client_ops.c.
1773 * Use IDENTIFY command to resolve the server information in the
1774 GETKEY command instead of INFO command. Affected file
1775 lib/silcclient/command.c.
1777 * All command reply functions in the client library now calls
1778 the pending command reply callbacks even if an error has
1779 occurred. The server has done this a long time and now it was
1780 time to move the client library to this as well. Now all
1781 errors can be delivered back to the pending command reply
1782 callbacks if necessary. Affected files are
1783 lib/silcclient/command[_reply].[ch].
1785 * Change the nickname on disconnection back to the username
1786 because in reconnect the server will enforce it to it anyway.
1787 Affected file irssi/src/silc/core/silc-servers.c.
1789 * Fixed a config file parsing bug in the Irssi SILC client.
1790 Affected file irssi/src/silc/core/clientconfig.c.
1792 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1794 * When printing the channel mode on JOIN, verify that the
1795 channel key and channel's HMAC are valid. Affected file
1796 irssi/src/silc/core/client_ops.c.
1798 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1800 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1801 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1802 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1804 * Removed channel key rekey task deleting from the function
1805 silc_server_save_channel_key. Affected file silcd/server.c.
1806 Added explicit timeout task context instead that is used to
1807 delete the task if we are registering a new task before the
1808 new task has elapsed.
1810 * When channel key rekey occurs the client library now saves
1811 the old channel key for a short period of time (10 seconds) and
1812 is able to use it in case some is still sending channel
1813 messages encrypted with the old key after the rekey. Affected
1814 file lib/silcclient/[idlist.h|client_channel.c].
1816 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1818 * Added check to the silc_server_new_id_real to not accept
1819 new ID if it is the sender's own ID. Affected file is
1820 silcd/packet_receive.c.
1822 * Assure that we do not announce ourself or the one we've
1823 sending our announcements when we're router and are announcing
1824 servers to our primary router. Affected file silcd/server.c.
1826 * Fixed silc_server_command_identify_check_client to assemble
1827 correct WHOIS packet. It send corrupted WHOIS packet and
1828 caused problem with router to router connections. Affected
1829 file silcd/command.c.
1831 Fixed also silc_server_command_whois_check the same way
1832 as for the IDENTIFY command.
1834 * Added new SilcIDListStatus to the server in the SilcIDListData
1835 structure. The status now includes the current status of
1836 the entry (like registered, resolved etc.). Affected file
1837 silcd/idlist.[ch]. Defined a bunch of different status types
1838 as well. This replaced the old boolean registered field as well.
1840 Added resolve_cmd_ident field to the SilcClientEntry structure
1841 too so that if the entry is for example being resolved so
1842 another command may attach to the same pending command reply
1843 without requiring to resolve the same entry again. This concept
1844 should optimize the WHOIS and the IDENTIFY resolving under
1845 heavy load by taking away unnecessary resolving for entries
1846 that are being resolved already.
1848 Added support for adding multiple pending commands for one
1849 command idenfier. Affected file silcd/command[_reply].[ch].
1851 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1852 before deleting the data. Otherwise the hash table will have
1853 freed data in comparison functions. Affected file is
1854 silcd/command_reply.c.
1856 * Fixed silc_idlist_replace_client_id to add the new entry to
1857 the cache with NULL nickname. Otherwise there will be invalid
1858 memory as the nickname after the nickname is freed. Affected
1859 file silcd/packet_receive.c.
1861 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1862 saved into wrong slots because the previous number of entries
1863 was not taken into account. Affected file silcd/idlist.c.
1864 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1866 * If we are router and we receive JOIN notify to a channel that
1867 does not have any users then notified client is marked as the
1868 channel founder, as it is it. The affected file is
1869 silcd/packet_receive.c
1871 * Added to the extended hash table API's table_del_*ext functions
1872 the destructor as argument too, so that the caller can decide
1873 which destructor to use or whether to use destructor at all.
1874 Affected file lib/silcutil/silchashtable.[ch].
1876 * Fixed ID Cache purging. It actually deleted the entries from
1877 the hash table after the data was freed. The hash table ended
1878 up comparing freed memory. The affected file is
1879 lib/silccore/silcidcache.c.
1881 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1883 * Fixed Irssi SILC client's KILL command's HELP syntax.
1885 * The USERS command now resolves the detailed user information
1886 if the userinfo field is missing. Affected file is
1887 lib/silcclient/command_reply.c.
1889 * Do not print error in silc_file_read if the read file does
1890 not exist. Just silently return NULL. Affected file is
1891 lib/silcutil/silcutil.c.
1893 * Fixed the silc_log_output to not wine about NULL filename
1894 and to not create some bogus " " filename. Affected file is
1895 lib/silcutil/silclog.c.
1897 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1899 * Fixed various printing bugs on the user interface in the
1900 Irssi SILC Client. Minor changes that were forgotten from
1903 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1905 * Fixed the configure.in.pre and the compilation and distribution
1906 environment to support the new autoconf 2.52. That version is
1907 now required to compile the CVS trunk.
1909 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1911 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1912 to generally parse user@fqdn format strings. Affected file
1913 lib/silcutil/silcutil.c.
1915 * Added nickname_format and nickname_force_format fields to the
1916 SilcClientParams structure. The first one defines the format
1917 for the nicknames that the library will enforce if the receives
1918 multiple same nicknames. The second one is boolean value and
1919 can be used to force the library to always enforce the format
1920 to the nicknames regardles whether there are multiple nicknames
1921 or not. This configurable formatting was employed to flexibly
1922 support accessing multiple nicknames from the user interface.
1923 The userinterface can now set the nicknames to what ever format
1924 they prefer. Affected file lib/silcclient/silcapi.h.
1926 Added function silc_client_nickname_format to the file
1927 lib/silcclient/idlist.c. It performs the nickname formatting.
1929 Added new field `hostname´ to the SilcClientEntry context.
1930 It holds the hostname of the client. Affected file is
1931 lib/silcclient/idlist.h.
1933 * Irssi SILC Client sets the nicknames in nick@hostn format.
1934 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1935 irssi/src/silc/core/silc-core.c.
1937 The WHOIS printing now also shows both the real nickname and
1938 the formatted nickname so that user knows how to access the
1939 user if there are multiple same nicknames cached. Affected
1940 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1941 printing formatting too to take the hostname now as a separate
1942 argument. The Affected file is
1943 irssi/src/fe-common/silc/modules-formats.[ch].
1945 * Changed the silc_client_get_clients_local to accept the formatted
1946 nickname as argument. It accepts the real nickname too but the
1947 formatted nickname can be used to find the true entry from
1948 multiple entries. Affected file lib/silcclient/silcapi.h and
1949 lib/silcclient/idlist.c.
1951 * Added nickname_format_parse field to the SilcClientParams.
1952 It is a callback function provided by the application to parse
1953 the nickname out of the formatted nickname string. The library
1954 calls it to get the nickname from the formatted string. Since
1955 the application generally knows better the format of the nickname
1956 string it parses it instead of the library, even though library
1957 encodes the formatted string. If the callback function is not
1958 provided then the library will use the string as is. The
1959 affected file is lib/silcclient/silcapi.h.
1961 * All the nickname strings passed to the client library in
1962 commands are now expected to be formatted nickname strings.
1963 If the command does not support the formatted nickname string
1964 it will assume that the sent string is the actual nickname.
1965 Affected file lib/silcclient/command.c.
1967 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1969 * Added public key authentication support to OPER and SILCOPER
1970 commands in the client library. Affected file is
1971 lib/silcclient/command.c.
1973 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1975 * Changed the get_auth_methdod client operation to be asynchronous.
1976 It can be async if the application resolves the authentication
1977 method from the server during the negotiation. Added new
1978 SilcGetAuthMeth completion callback that the application will
1979 call after resolving the authentication method.
1981 Added function silc_client_request_authentication_method that
1982 the application can use to resolve the authentication method
1983 from the server. Added also SilcConnectionAuthRequest callback
1984 that the library will call after the server has replied. The
1985 application can call this function if it does not know the
1986 current authentication method.
1988 Affected files are lib/silcclient/client.c and
1989 lib/silcclient/silcapi.h.
1991 * The Irssi SILC client now automatically resolves the authentication
1992 method incase any configuration information is not present (and
1993 currently there never is). The affected file is
1994 irssi/src/silc/core/client_ops.c.
1996 * Fixed public key authentication from the client library.
1997 Affected file lib/silcclient/protocol.c. Changed also the
1998 protocol specification about the public key authentication in
1999 the connection authentication protocol. The actual data to be
2000 signed is now computed with a hash function before signing.
2002 * Fixed the public key authentication from the server as well.
2003 Affected file silcd/protocol.c.
2005 * Removed the mlock()'s from the memory allocation routines.
2006 Affected file lib/silcutil/silcmemory.c. The ./configure does
2007 not check anymore for the mlock(). Affected file is
2010 * Fixed USERS command in server to allow the execution of the
2011 command for private and secret channels if the client sending
2012 the command is on the channel. Affected file silcd/command.c.
2014 * Fixed silc_client_get_clients_local to return the clients
2015 count correctly. It could return wrong value. Affected file
2016 lib/silcclient/idlist.c.
2018 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2020 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2021 types. The assembler optimizations seemed not to like 64-bit
2022 data types. The assmebler optimizations thus are now enabled
2023 also for BSD systems as opposed to only enable them for Linux.
2025 * Do not check for threads at all on BSD systems. Affected
2026 file configure.in.pre.
2028 * Removed -n and -h options from the Irssi SILC Client since
2029 they are not used in silc.
2031 * Fixed the prime generation to assure that the first digit
2032 of the generated random number is not zero since our conversion
2033 routines does not like number strings that starts with zero
2034 digit. If zero digit is seen the random number is regenerated.
2035 This caused some corrupted RSA keys when the zero first digit
2036 was met. Affected file lib/silcmath/silcprimegen.c.
2038 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Fixed WIN32 configuration in the ./configure script.
2041 Fixed to include xti.h on environments that has it.
2042 Patches by Carsten Ilchmann and andrew.
2044 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2046 * Changed the silc_id_create_client_id to be collision
2047 resistant. It is now assured that there cannot be created
2048 two same client ID's. I suspect that some weird bugs in
2049 the server were actually caused by duplicate Client IDs.
2050 Affected file silcd/serverid.[ch]. A router receiving
2051 new ID now also assures and informs the sending server
2052 if the ID caused collision.
2054 * Changed the silc_id_create_channel_id to also assure that
2055 there are no collisions.
2057 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2059 * Statement about ignoring the Mutual Authentication flag when
2060 performing rekey with PFS was a bit misleading. It is ignored
2061 if it was set in the initial negotiation, it cannot be even
2062 set in the rekey. Fixed in the ke-auth draft. Started the
2063 new versions of the protocol drafts in the doc/.
2065 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2067 * Fixed a bug in silc_client_command_identify_save when saving
2068 new channel information. The channel name was no duplicated
2069 and caused crash on exit. Affected file is
2070 lib/silcclient/command_reply.c.
2072 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2074 * Fixed the getkey command handling in the server. Send just
2075 empty OK reply to the sender if the key could not be fetched
2076 (but everything else was ok, like the key just was not available).
2077 Changed the public key parameter to optional in the protocol
2078 specs so that empty OK reply can be sent. Affected file
2081 Added a message to Irssi SILC client to tell to user if the
2082 server did not return a public key.
2084 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2086 * Fixed a channel key regeneration bug. It registered new
2087 timeout tasks exponentially until all system resources were
2088 used. Affected file silcd/server.c.
2090 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2092 * Added the SILC Document generator to the scripts/silcdoc.
2093 It can be used to generate the Toolkit Reference Manual out
2094 of the source tree. Internally it will also use the RoboDoc
2095 generator now imported in util/robodoc.
2097 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2099 * Added couple of return's in rekey protocol if error orccurred
2100 during the protocol. The execution must be terminated.
2101 Affected file silcd/protocol.c. Also, terminate the protocol
2102 always with timeout.
2104 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2106 * The client's Client ID was created initally from the wrong
2107 nickname (it could have been in format nick@host) in the
2108 silc_server_new_client. Affected file silcd/packet_receive.c
2110 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2112 * Added some SILC_LOG_ERROR's to various error conditions
2113 if client could not be added to ID cache. Affected files
2114 silcd/packet_receive.c and silcd/server.c.
2116 * When client's sock->user_data is freed, NULL also the
2117 client->router and client->connection pointers. Added check
2118 for these pointers being NULL to various places around the
2119 code. Affected file silcd/server.c.
2121 * Added client->data.registered == TRUE checks to various
2122 places around the code to assure that unregistered client's
2123 are not handled when it is not allowed. Affected file
2126 * Added `bool registered' fields to all
2127 silc_idlist_[server|client]_get_* routines to indicate whether
2128 the fetched client needs to be registered or not. Affected
2129 file silcd/idlist.[ch].
2131 * Add your own entry as registered to the ID cache in the
2132 server. Affected file server.c.
2134 * Fixed a bug in silc_server_new_server. The SilcServer was
2135 set as the new server's context instead of SilcServerEntry.
2136 This naturally caused some weird bugs.
2138 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2140 * Do not delete the channel rekey task when adding it
2141 for in silc_server_create_channel_key.
2143 * Changed the silc_server_create_channel_key to return
2144 TRUE or FALSE to indicate the success of the channel key
2147 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2149 * Fixed MSVC++ project files and added missing files to
2150 Makefiles under win32/.
2152 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

2155 does not have it defined. Affected files are
2156 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2158 * Fixed buffer overflow from Irssi SILC Client. Affected
2159 file irssi/src/fe-common/core/themes.c.
2161 * Fixed double free in client library in the file
2162 lib/silcclient/client.c when disconnecting from server.
2164 * Applied double free patch from cras to Irssi SILC client.
2165 Affected files irssi/src/core/[modules/expandos].c
2167 * Fixed the disconnection handling to Irssi SILC Client.
2168 The application must call silc_client_close_connection
2169 in ops->connect client operation in case of failure of
2170 the connection. Affected file is
2171 irssi/src/silc/core/client_ops.c.
2173 * Do not set sock->protocol to NULL in the function
2174 silc_client_close_connection after executing the protocol's
2175 final callback since the sock might not be valid anymore.
2176 Affected file lib/silcclient/client.c.
2178 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2180 * Do not enable SILC_THREADS if the linking with libpthread
2181 did not happen. Affected file configure.in.pre.
2183 * Added notion to protocol specification that server must
2184 verify the sent authentication payload with CMODE when
2185 setting the channel founder key. Implemented it to the
2186 server. Affected file silcd/command.c.
2188 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2190 * Added _EXTRA_DIST SILC distribution variable to the
2191 distributions file. It is used to conditionally add extra
2192 files or directories to the specific distribution. Affected

2198 * Added README.WIN32 for instructions to compile the Toolkit
2201 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2203 * Fixed a double free in disconnection in the server. Affected
2204 file is silcd/server.c.
2206 * Fixed the lib/silcske/groups.c to work now also with GMP
2207 MP library. The string conversion did not work when using
2208 specific base and the base is indicated in the string as well.
2210 * Created win32/ directory which now includes MSVC++ specific
2211 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2212 It will appear only in the toolkit distribution
2214 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2216 * Changed the key material distribution function in case when
2217 the hash output is too short. The data is now concatenated
2218 a bit differently than it used to. Made the change to the
2219 SKE protocol specification.
2221 * Added better GMP detection to configure.in.pre. A patch
2224 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2226 * Fixed a minor bug in SKE that might cause some problem on
2227 some platforms. Affected file lib/silcske/silcske.c.
2229 * Added the cookie checking for initiator in the SKE. It checks
2230 that the responder returns the sent cookie unmodified. The
2231 affected file is lib/silcske/silcske.c. Added new SKE
2232 error type INVALID_COOKIE that can be sent during the
2233 negotiation. Fixed some memory leaks as well.
2235 * Added the "invalid cookie" error message to Irssi SILC client's
2238 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2240 * Added `task_max' field to the SilcClientParams to indicate
2241 the maximum tasks the scheduler can handle. If set to zero,
2242 default values are used. Affected file lib/silcclient/silcapi.h.
2244 * Fixed memory leaks in silc_client_close_connection. Affected
2245 file lib/silcclient/client.c.
2247 * Added silc_client_del_client_entry to client library to free
2248 all memory of given client entry. Affected file is
2249 lib/silcclient/idlist.[ch].
2251 * Added new functions silc_client_del_channel and
2252 silc_client_del_server to delete channel and server entries.
2253 Affected file lib/silcclient/[silcapi.h/idlist.c].
2255 * Removed silc_client_del_client_by_id from silcapi.h.
2257 * Fixed the INFO command to return the server's own info
2258 correctly when querying by Server ID. Affected file is
2261 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2263 * Removed the non-blocking settings in WIN32 code in the
2264 silc_sock_[read/write] and added SleepEx instead. Affected
2265 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2266 of input data is now checked with FIONREAD and ioctlsocket.
2268 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2270 * Call silc_schedule_task_del_by_context in the
2271 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2272 Affected file lib/silccore/silcprotocol.c.
2274 * Call silc_protocol_cancel for active protocols in the
2275 silc_server_close_connection if the funtion
2276 silc_server_free_sock_user_data has not been called.
2277 Affected file silcd/server.c.
2279 * Generic tasks cannot be deleted using the del_by_fd
2280 task deleting function since generic tasks does not match
2281 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2283 * Added a notion to SILCOPER help file that the SILCOPER works
2284 only on router server, not on normal server.
2286 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2288 * Added for WIN32 support for the new scheduler as well.
2289 Affected file lib/silcutil/win32/silcwin32schedule.c.
2291 * Fixed the SHA1 implementation to work on various platforms.
2293 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2295 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2296 API. It is part of the scheduler now. Everything else is
2297 as previously but some functions has changed their names.
2298 Checkout the lib/silcutil/silcschedule.h for the interface.
2299 Updated all applications to use the new interface. Affected
2300 files are lib/silcutil/silcschedule.[ch].
2302 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2304 * Found a bug in the SKE implementation. The HASH value,
2305 specified by the protocol, was not computed correctly. The
2306 public key of the responder was not added to the computation
2307 even though it is mandatory. Affected file lib/silcske/silcske.c.
2308 This unfortunately causes incompatibilities with older
2309 clients and servers.
2311 * Added WIN32 specific network init and uninit functions:
2312 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2313 the Winsock2. Affected file lib/silcutil/silcnet.h and
2314 lib/silcutil/win32/silcwin32net.c.
2316 * Set the socket always to nonblocking mode on WIN32 after
2317 reading data or writing data. Affected file is
2318 lib/silcutil/win32/silcwin32sockconn.c.
2320 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2322 * Fixed various compilation problems under WIN32. Affected
2323 files lib/silcutil/win32/silcwin32thread.c and
2324 lib/silcutil/win32/silcwin32schedule.c.
2326 * Removed all _internal.h #includes from public header
2327 files. Internal headers must never be included from
2330 Removed also the lib/silcske/payload_internal.h file.
2332 * All include files that may be needed (public and some others
2333 included by the public headers) by application developers are
2334 now copied to the ./includes directory. It does not copy any
2335 internal headers. Affected file Makefile.defines.pre and all
2336 Makefile.am's under lib/ and subdirs.
2338 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2340 * Do not change the ~/.silc directory's permissions automatically.
2341 Affected file irssi/src/silc/core/clientutil.c.
2343 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2345 * Do not cancel the protocol in silc_server_close_connection
2346 it might cause recursion. Now cancelled in the function
2347 silc_server_free_sock_user_data. Affected file silcd/server.c.
2349 * Fixed the silc_server_remove_clients_by_server to regenerate
2350 the channel keys correctly finally. Added also new function
2351 silc_server_remove_clients_channels to actually do it.
2352 Affected file silcd/server.c.
2354 * Fixed the silc_server_new_channel to not crash by giving
2355 wrong router to the new channel. Affected file is
2356 silcd/packet_receive.c.
2358 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2361 which is given as argument to the silc_client_alloc now.
2362 It can be used to configure the client and set various parameters
2363 that affect the function of the client.
2365 * The USERS command in server did not check whether the channel
2366 is private or secret. Affected file silcd/command.c.
2368 * Added new argument to the USERS command in protocol specification.
2369 The USERS command now can take the channel name as argument
2370 as well. Added support for this in client and server and
2371 updated the protocol specs.
2373 * Completed the GETKEY command in client. It can be now used
2374 to fetch also servers public key not only some clients.
2375 Affected files lib/silcclient/command[_reply].c.
2377 * Added silc_client_get_server to return server entry by the
2378 server name. Affected files lib/silcclient/silcapi.h and
2381 * Redefined the IDENTIFY command in protocol specification to be
2382 more generic. It now can be used to query information about
2383 any entity in the SILC Network, including clients, servers and
2384 channels. The query may be based either the entity's name
2385 or the ID. Added support for this in both client and server.
2387 Affected files silcd/command.c and lib/silcclient/command.c
2388 and command_reply.c.
2390 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2391 the _from_client and _from_server functions. Affected file
2394 * Added silc_client_get_channel_by_id_resolve to the file
2395 lib/silcclient/silcapi.h to resolve channel information by
2396 its ID. Added also silc_client_get_channel_by_id that
2397 does not resolve it from the server.
2399 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2401 * Added SilcServerEntry context into the client library
2402 to represent one server. The INFO command now allocates
2403 these to save the resolved server info. For now on the
2404 client library will also keep information about servers,
2405 connected and resolved with INFO.
2407 The INFO command now allocates the SilcServerEntry context
2408 and saves the server info there. The COMMAND_REPLY in
2409 the INFO now returns the parameters to application in
2410 same order as defined in the protocol specification.
2412 The entries are cached in the client->server_cache.
2414 * The INFO command is now issued after received the Client ID
2415 from the server. Affected file lib/silcclient/client.c.
2417 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2418 to the application as the mode changer might be server.
2419 It is guaranteed that NULL is not returned anymore to the
2420 application. Affected file lib/silcclient/client_notify.c.
2422 The ID Type is now also passed to the application so that
2423 it can check whether the returned entry is SilcClientEntry
2426 Added new function silc_client_get_server_by_id to return
2427 the server entry by ID. Affected files are the
2428 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2430 * Do not create the channel in the Irssi SILC Client when issuing
2431 the JOIN command but when received the sucessful JOIN command
2432 reply. Otherwise the channel might get created even though we
2433 could not join it. The Affected file is
2434 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2436 * Fixed a channel joining bug in router. The router must also
2437 check the channel modes, invite and ban lists etc. when serving
2438 the JOIN command sent by normal server. Affected file is
2439 silcd/command.c. The router now resolves the client's
2440 information from the server who sent the JOIN command if it
2441 does not know it, and processes the JOIN command only after
2444 * Changed the SilcCommandCb to take new argument; void *context2.
2445 Affected file lib/silccore/silccommand.h
2447 The second argument in the command callbacks in the server now
2448 includes the SilcServerCommandReplyContext if the command was
2449 called as pending command callback from the command reply.
2450 Otherwise it is NULL. When called as pending the status of the
2451 command reply will be checked and if it was erronous the
2452 error will be sent to the original sender of the command.
2453 This way the client always receives the error messages even
2454 though the server was actually the one who received the error
2455 when it resent the command to router, for example. Affected
2456 files silcd/command[_reply].[ch].
2458 * Fixed sending WHOWAS command's error message to client if
2459 the requested client could not be found. It was missing.
2462 * Changed the CMODE and CUMODE commands reply arguments in the
2463 protocol specification. The Channel ID is now sent in both
2464 of the commands to identify the channel. Implemented this
2465 new feature to the client and server. Affected files
2466 lib/silcclient/command_reply.c and silcd/command.c.
2468 * Made better checks for invite and ban lists in the JOIN
2469 command in server. Affected file silcd/command.c.
2471 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2473 * The server now performs the incoming host IP/DNS lookup
2474 using the silc_socket_host_lookup and thus does not block
2475 the server anymore. Affected file silcd/server.c.
2477 * Completed the multi-thread support for SILC Scheduler in
2478 the lib/silcutil/silcschedule.c.
2480 * Fixed the configure.in.pre to detect the pthread correctly
2483 * Fixed a deadlock in silc_task_queue_wakeup in the file
2484 lib/silcutil/silctask.c.
2486 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2488 * Added new function silc_schedule_wakeup that is used in
2489 multi-threaded environment to wakeup the main thread's
2490 schduler. It needs to be used when a thread adds a new task
2491 or removes a task from task queues. After waking up, the
2492 scheduler will detect the task queue changes. If threads
2493 support is not compiled in this function has no effect.
2494 Implemented the wakeup mechanism to both Unix and WIN32
2495 systems. Affected files are lib/silcutil/silcschedule.[ch],
2496 lib/silcutil/unix/silcunixschedule.c and the
2497 lib/silcutil/win32/silcwin32schedule.c.
2499 * Added new function silc_task_queue_wakeup to wakeup the
2500 scheduler by the specified task queue. Affected file
2501 lib/silcutil/silctask.[ch].
2503 * The silc_socket_host_lookup_start now wakes up the scheduler
2504 after adding the timeout task. Affected file is
2505 lib/silcutil/silcsockconn.c.
2507 * The silc_socket_host_lookup is synchronous now if the threads
2508 support is not compiled in. However, the callback is still
2509 called asyncronously through the scheduler, anyway. Affected
2510 file lib/silcutil/silcsockconn.c.
2512 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2514 * Added new function silc_socket_host_lookup to perform
2515 asynchronous IP and FQDN lookups for the socket connection.
2516 Affected files lib/silcutil/silcsockconn.[ch].
2518 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2520 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2521 that may or may not compile the mutex support in.
2523 Changed the silc_mutex_alloc interface. It allocates the
2524 mutex now to the sent pointer and returns TRUE or FALSE.
2526 Affected file lib/silcutil/silcmutex.h.
2528 * Wrote the SILC Task Queue interface to support multi-threads.
2529 Affected file lib/silcutil/silctask.[ch].
2531 * Wrote the SILC Scheduler to support multi-threads. Affected
2532 file lib/silcutil/silcschedule.c.
2534 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2536 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2537 in lib/silcutil/win32/.
2539 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2541 * Defined SILC Mutex API and SILC Thread API and implemented
2542 them for Unix. Affected files are
2543 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2544 lib/silcutil/unix/silcunixmutex.c and
2545 lib/silcutil/unix/silcunixthread.c.
2547 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2549 * Fixed the silc_server_remove_clients_by_server's channel
2550 key re-generation. The hash table handling was incorrect
2551 and would not work with many channels. Affected file is
2554 * Fixed some memory leaks around the server code.
2556 * Rewrote the silc_server_get_users_on_channel to support IPv6
2557 based Client ID's. Affected file silcd/server.c.
2559 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2560 specification. However, a separate document must be written
2561 to define the detailed signing procedure and the payload
2562 associated with the flag. Defined the flag to the
2563 lib/silccore/silcchannel.h as well.
2565 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2567 * Changed the dynamic tables to static size tables in the
2568 lib/silccrypt/silchmac.c.
2570 * Removed GCC dependencies from the code. A patch by cras.
2572 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2574 * Do not show the error "Error receiving packet bla bla"
2575 in server if it really was not an error (-2 means that reading
2576 is pending). Affected file silcd/server.c.
2578 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2580 * Fixed a possible crash in silc_server_remove_clients_by_server
2581 in silcd/server.c. Fixed there also some memory leaks.
2583 * Fixed the silc_idlist_replace_client_id. It could replace
2584 wrong key in the hash table. Affected file silcd/idlist.c.
2586 * Do not check whether there are global users on the channel
2587 if the channel->global_users is FALSE. Affected functions
2588 silc_server_remove_from_one_channel and
2589 silc_server_remove_from_channels in silcd/server.c. Also,
2590 do not check if the removed client is local as we can be
2591 sure that global client was not removed from the channel
2592 and checking for global users is not needed.
2594 * The silc_server_remove_clients_by_server now re-generates
2595 the channel keys correctly for those channels that had
2596 clients removed from them. Affected file silcd/server.c.
2598 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2600 * Found the reason of random crashes in the server. We weren't
2601 ignoring the SIGPIPE signal (which can be sent in write())
2602 and it crashed the server. Affected file silcd/silcd.c.
2604 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2606 * Assure that sock->user_data is not NULL in the function
2607 silc_server_packet_send in silcd/packet_send.c.
2609 * Disconnect the remote connection if it could not be added
2610 to any ID lists in the server. The affected file is
2613 * Check in silc_server_packet_send[_real/dest] that the
2614 socket is not disconnecting and ignore the data if it is.
2615 Affected file silcd/packet_send.c.
2617 * Define inline to __inline on native WIN32 compilation.
2618 Affected file includes/silcwin32.h.
2620 * Added some explicit type casts for inline code since MSVC
2621 require them. Affected files lib/silcutil/silcbuffer.h,
2622 lib/trq/silcdlist.h and lib/trq/silclist.h.
2624 * Print warning in log files from now on if the packet
2625 decryption fails. Affected file silcd/server.c.
2627 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2629 * Changed the `say' client operation's interface to accept
2630 new `type' argument to indicate the type of the message sent
2631 by the library. The application may filter the library's
2632 messages according the type. The affected file is the
2633 lib/silcclient/silcapi.h.
2635 * Added two new functions to lib/silcclient/silcapi.h:
2636 silc_client_del_client and silc_client_del_client_by_id.
2637 Affected file lib/silcclient/idlist.c.
2639 * Moved the clientincludes.h from includes/ to silc/ and
2640 serverincludes.h from includes/ to silcd/.
2642 * The modes for the CMODE and CUMODE are now passed as
2643 uint32 for application with COMMAND_REPLY. The affected
2644 file is lib/silcclient/command_reply.c.
2646 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2648 * /WHOIS without arguments shows client's own information.
2649 Affected file lib/silcclient/command.c.
2651 * Changed PING to not accept any arguments. The specs
2652 says that client can ping only the connected server so
2653 requiring an argument is not needed. Affected file is
2654 lib/silcclient/command.c.
2656 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2658 * Fixed a fatal bug in private message sending and reception
2659 encryption and decryption when using private message keys.
2660 The implementation was incorrect and did not follow the
2661 specification. It causd that some of the message were
2662 lost since it did not use the sending and receiving keys
2663 as the protocol suggests. This has been fixed and will cause
2664 incompatibilities with older clients when sending private
2665 message encrypted with private message keys. Affected files
2666 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2667 and various other in Irssi SILC Client.
2669 Added `responder' boolean argument to the functions
2670 silc_client_add_private_message_key[_ske] to indicate when
2671 the key is added as responder or initiator of the key
2674 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2676 * Removed the silc_ske_check_version function and created
2677 a SilcSKECheckVersion callback. Added also a function
2678 silc_ske_set_callbacks that is now used to set all SKE
2679 callbacks. The callback functions are not given to
2680 the SKE functions anymore, but this function is used to
2683 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2685 * Added `silc_version' argument to the silc_client_alloc
2686 to define the version of the application for the library.
2687 The library will use the version string to compare it
2688 against the remote host's (usually a server) version
2689 string. Affected file lib/silcclient/silcapi.h
2691 * Added the KE protocol context to Key Agreement context
2692 in client library so that we can abort the SKE if it
2693 is in process when we get timeout. Affected file is
2694 lib/silcclient/client_keyagr.c.
2696 * Do not resolve the client ID forever if it returns in the
2697 first time that such client does not exist. This was done
2698 for example with private message. Affected file is
2699 lib/silcclient/client_prvmsg.c.
2701 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2703 * Do not add regex.h for WIN32. The affected file
2704 includes/silcincludes.h.
2706 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2707 not work yet 100%. It generates the DLL's automatically
2708 when compiling with --with-win32 under cygwin.
2710 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2712 * lib/contrib/regex.c is not compiled on WIN32.
2714 * Added silc_net_get_socket_opt function to the
2715 lib/silcutil/silcnet.h.
2717 * Added includes/silcwin32.h for WIN32 specific includes
2720 * Do not use ptime structure or any of the posix process
2721 functions on WIN32 in lib/silccrypt/silrng.c.
2723 * Added silc_gettimeofday to provide generic function
2724 for struct timeval on all platforms. Added the function
2725 to lib/silcutil/silcutil.h.
2727 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2729 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2730 library as they clearly belong there. As a plus side we
2731 can make the actual socket connection routines platform
2734 Added also new generic function silc_socket_read and
2735 silc_socket_write (that used to be silc_packet_[read/write].
2736 The implementation of these are platform specific.
2738 * Added WIN32 specific routines of silc_socket_[read/write]
2739 to lib/silcutil/win32/silcwin32sockconn.c.
2741 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2743 * Added preliminary support for native WIN32 compilation under
2744 cygwin (using the -mno-cygwin option for GCC) to the
2745 ./configure.in.pre. The --with-win32 now prepares the
2746 compilation for native WIN32.
2748 * Rewrote the SILC Scheduler interface in the file
2749 lib/silcutil/silcschedule.h. The scheduler is now context
2750 based and does not have anymore any global static scheduler.
2751 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2752 and created lib/silcutil/win32 directory for WIN32 based
2755 * Added Unix specific network routines to the
2756 lib/silcutil/unix/silcunixnet.c and the old
2757 lib/silcutil/silcnet.c includes now only generic routines.
2759 Added WIN32 specific network routines to the
2760 lib/silcutil/win32/silcwin32net.c.
2762 * Added Unix specific utility functions from the
2763 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2765 * Added WIN32 SILC Scheduler to the file
2766 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2769 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2771 * Do not handle JOIN notify in the server if the target client
2772 is not registered (idata->registered == FALSE). The affected
2773 file is silcd/packet_receive.c.
2775 * Update the nickrec->founder in event_cumode in the Irssi SILC
2776 client. Affected file irssi/src/silc/core/silc-channels.c.
2778 * Fixed the CUMODE_CHANGE notify handling in the server when
2779 server and router are announcing their clients on channels.
2780 Now the mode changes are saved and notified correctly. The
2781 affected file is /silcd/packet_receive.c.
2783 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2784 They really did not replace the cache entry in the ID Cache.
2785 Now they do that. Affected file silcd/idlist.c.
2787 * Fixed the KICK notify handling in the Irssi SILC client to
2788 update the channel records so that the kicked client does not
2789 appear to be on the channel. The affected file is
2790 irssi/src/silc/core/silc-channels.c.
2792 * Always update the conn->current_channel when executing command
2793 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2795 * Fixed the KILL notify handling in Irssi SILC client to remove
2796 the killed client on all channels.
2798 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2800 * Fixed the silc_parse_command_line to remove extra spaces
2801 from the start and end of the arguments. Affected file is
2802 lib/silcutil/silcutil.c.
2804 * Cancel and free any active protocol in the function
2805 silc_server_close_connection. Affected file silcd/server.c.
2807 * Cancel and free any active protocol in the function
2808 silc_client_close_connction. Affected file is
2809 lib/silcclient/client.c.
2811 * Do not execute the KILL command for clients that are in
2812 history (ie. they are not in the network). Affected file is
2815 * Fixed KILL notify handling, client does not crash anymore.
2816 Affected file irssi/src/silc/core/silc-channels.c.
2818 * Reduced the default packet buffer size from 2048 to 1024 in
2819 lib/silccore/silcpacket.c.
2821 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2822 counter to the SKE context that is incresed when the SKE library
2823 performs async operation outside the library. If the outside
2824 process frees the SKE context and FREED status will be set
2825 and the library will detect after the sync operation that the
2826 libary is freed. The affected files are
2827 lib/silcske/silcske[_status].[ch].
2829 * Resolve the client entry information in the function
2830 silc_client_channel_message to assure that NULL pointer is not
2831 passed as client entry to the application. */
2833 * Fixed the task timeout calculation to assure that there is
2834 never negative timeouts. The affected file is
2835 lib/silcutil/silcschedule.c.
2837 * Fixed the channel user mode notification sending in server.
2838 It was sent point-to-point to the router (or to server by router)
2839 but it needs to be destined to a channel. The routines now
2840 supports sending the channel user mode notifys to the channels
2841 when announcing clients and channels. Affected files are
2842 silcd/server.c and silcd/packet_receive.c.
2844 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2845 It did not actually replace the old channel entry in the cache.
2846 Affected file lib/silcclient/client_notify.c.
2848 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2850 * Fixed a possible crash in silc_packet_send_prepare. It now
2851 assures always that there is enough space in the buffer and
2852 at the tail area of the buffer (for MAC).
2854 Fixed the inbound buffer reallocation in silc_packet_read.
2855 It was old code and did not handle the reallocation correctly.
2858 The affected file is lib/silccore/silcpacket.c.
2860 * Fixed buffer overflow in silc_parse_nickname in the file
2861 lib/silcutil/silcutil.c.
2863 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2865 * make install generates new server keys only if there is not
2868 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2870 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2871 Added check that if the NOREPLY is set then we will not send
2872 the away message. This avoids infinite loop of away messages
2873 if both clients are away. The affected file is
2874 lib/silcclient/client_prvmsg.c.
2876 * Fixed client crash if /NICK was given without arguments.
2877 Affected file lib/silcclient/command.c.
2879 * Server does not send the invite list in INVITE command back
2880 to the client if the list was not altered. Added this notion
2881 to the protocol spec as well. Affected file silcd/command.c.
2883 Fixed possible crash in INVITE command by checking the
2884 value of silc_server_get_client_route command.
2886 * Fixed the INVITE notify type handling. The arguments are now
2887 taken in correct order and client does not crash. The affected
2888 file is irssi/src/silc/core/silc-channels.c.
2890 Removed the "Inviting xxx to channel" message from the
2891 client library away and let the application handle it.
2892 Affected file lib/silcclient/command.c. Added that message
2893 to Irssi SILC client's message formats.
2895 * Fixed CMODE command crash in client. It now checks the
2896 amount of arguments correctly and does not crash. The affected
2897 file is lib/silcclient/command.c.
2899 * Do not create new channel automatically in silc_channels_join
2900 but check whether the channel by that name already exists.
2901 Affected file irssi/silc/core/silc-channels.c.
2903 * Do not send the SERVER_SIGNOFF to router if the disconnected
2904 entity was the router. Affected file silcd/server.c.
2906 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2907 SILC client as it was missing from there.
2909 Added the handling of the KICK notify to the Irssi SILC client
2910 as it was missing. Added "you have been kicked" message to
2911 Irssi SILC client's message modules formats.
2913 Added the handing of the KILL notify to the Irssi SILC client
2914 as it was missing. Added the kill message module formats
2917 The affected file is irssi/src/silc/core/silc-channels.c.
2919 * The router did not save the channel mode the server announced.
2920 Affected file silcd/packet_receive.c.
2922 * Fixed a possible crash in INFO command in server. If the
2923 server did not provide the server info it crashed. Affected
2924 file silcd/command.c.
2926 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2928 * Fixed the GETKEY command in the server to check also the
2929 global list. Otherwise the GETKEY would not work correctly
2930 in normal SILC server. Affected file silcd/command.c.
2932 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2934 * Fixed GETKEY crash, it crashed if the command did not succseed.
2936 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2938 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2939 is now real and not just an macro interface to GMP.
2941 Removed the entire GMP from the source tree and imported new
2942 NSS MPI library instead. Reason for removing GMP is that it is
2943 extremely large and compiles extremely slow. The NSS MPI
2944 is only a few files and compiles in less than 10 seconds.
2945 The speed is also about the same as GMP. The MPI is imported
2946 to lib/silcmath/mpi.
2948 If the system has GMP installed we will still use the GMP.
2949 If it is not then the NSS MPI will be compiled.
2951 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2953 * Merged a long nickname (127 characters long) crash bugfix from
2954 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2956 * Merged a freed memory reference bugfix from Irssi CVS tree.
2957 Affected file irssi/src/core/commands.c.
2959 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2961 * Added the server's public key sving and verification to the
2962 server when performing the SKE. This was missing and the
2963 remote server's (or router's) public key was accepted without
2964 checking whether we have it previously or trust it at all.
2965 Affected file silcd/protocol.c.
2967 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2969 * Check in the silc_server_timeout_remote if protocol is active
2970 and make sure that the protocol's final callback is called so
2971 that all memory if freed. Affected file silcd/server.c.
2973 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2975 * silc_server_whois_send_reply crashed the server if the nickname
2976 was 127 characters long. Affected file silcd/command.c.
2978 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2980 * Added sanity check to the silc_server_new_client. If the hostname
2981 is provided inside username then check that the provided hostname
2982 really is the same as the resolved one. If the hostname was not
2983 resolved then check it from the public key. Affected file is
2984 silcd/packet_receive.c.
2986 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2987 if the server disconnected us and the connection is not valid
2988 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2990 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2991 the library to the lib/silcutil/silcutil.[ch].
2993 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2995 * Close log file after open. Affected file
2996 lib/silcutil/silclog.c.
2998 * Check whether sock == NULL in silc_client_send_packet and return
2999 if it is. Affected file lib/silcclient/silcclient.c.
3001 * Check rec->entry == NULL in the Irssi SILC Client before
3002 sending the channel message. Affecte file is
3003 irssi/src/silc/core/silc-servers.c.
3005 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Merged a splitted window bugfix from Irssi CVS tree. The
3008 affected file is irssi/src/fe-text/textbuffer-view.c.
3010 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3011 It did not print nickname.
3013 * Improved the distributions system a bit.
3015 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3017 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3018 irssi/src/fe-text/gui-window.c.
3020 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3021 to in-active server. The affected file is
3022 irssi/src/silc/core/client_ops.c.
3024 * Resolve the client in USERS command reply if the entry does
3025 not have username resolved. The affected file is
3026 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3027 command to WHOIS command to really resolve stuff. The USERS
3028 is not used any more in any critical section so WHOIS can
3029 be used even though it might be slower than IDENTIFY.
3031 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3034 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3036 * Changed the protocol API a bit more consistent in the
3037 lib/silccore/silcprotocol.[ch].
3039 * Changed the following headers to ROBODoc format:
3041 lib/silccore/silcpayload.h
3042 lib/silccore/silcprotocol.h
3043 lib/silccore/silcsockconn.h
3045 All core library headers are now formatted.
3047 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3049 * Fixed a bug in Irssi SILC client; do not show that you are
3050 server/router operator if you really are not. Affected file is
3051 irssi/src/silc/core/client_ops.c.
3053 * Renamed silc_command_free_payload to silc_command_payload_free.
3054 Affected file lib/silccore/silccommand.h
3056 * Added silcmath.h to include the prototoypes of various routines
3057 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3060 * Changed the following headers to ROBODoc format:
3062 lib/silccore/silcchannel.h
3063 lib/silccore/silccommand.h
3064 lib/silccore/silcid.h
3065 lib/silccore/silcidcache.h
3066 lib/silccore/silcmode.h
3067 lib/silccore/silcnotify.h
3068 lib/silccore/silcpacket.h
3069 lib/silcmath/silcmath.h
3071 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3073 * Added checking to the server code not to start the server if
3074 ciphers and stuff are not configured properly. Affected files
3075 silcd/serverconfig.[h] and silcd/server.c.
3077 * Changed the layout of the header files of the public interfaces
3078 in the SILC libraries. The new layout supports ROBODoc
3079 documentation tool (and some others) so that it is easy to create
3080 a library reference manual. All the other headers and source
3081 code must still follow the CodingStyle document. Also source
3082 code must not include these ROBODoc stuffs, only the headers.
3083 Furthermore, all public interface headers must now be named
3084 by using `silc' prefix, example: silcapi.h, silccipher.h.
3085 Some files were renamed due to this. All the other headers
3086 must not be used as public interfaces. I will update the
3087 CodingStyle document later. Changed following headers, so far:
3089 lib/silcclient/silcapi.h
3090 lib/silccore/silcauth.h
3091 lib/silccore/silcprivate.h
3092 lib/silccrypt/silcdh.h
3094 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3098 * Removed silc_client_packet_send_flush from the client library
3099 as it is not needed. Affected file lib/silcclient/client.[ch].
3101 * Added printing of message of unresolved authentication method
3102 to the Irssi SILC client. Added it to the module formats.
3103 Removed the same message from the client library.
3105 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3107 * Added new distribution feature, DISTLABEL. Every distribution
3108 can define own preprocessor label that can be used in the
3109 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3110 file distributions, acconfig.h.pre and prepare.
3112 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3114 * Added Makefile.defines_int to include the actual definitions
3115 for Makefile.defines.in. Tested the new distribution system,
3116 created distributions and tested installation.
3118 * Added AWAY message printing to the Irssi SILC client. Added
3119 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3121 * Added SCONNECT command to call the SILC's CONNECT command.
3122 Cannot use CONNECT directly since Irssi uses that internally.
3123 Affected file irssi/src/silc/core/silc-servers.c.
3125 Added ACTION local command. It is same as ME command but takes
3126 the channel as mandatory argument.
3128 Rewrote some of the Irssi's help files to suite for SILC
3131 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3133 * Added Makefile.defines[.in] that should for now on be included
3134 in all Makefile.am file in the source tree. That file includes
3135 all common compilation definitions for SILC source tree.
3137 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3139 * Minor changes to the ./prepare script to change the package
3140 name according the distribution name to the configure.in.
3142 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3144 * Created new distribution system. Added file `distributions'
3145 that defines all the distributions that can be created out of
3146 the SILC source tree. The ./prepare script now reads that
3147 file to determine how to prepare the distributions. The
3148 first argument to the ./prepare is the name of the distribution
3149 and second is the version of the distribution. If given
3150 without arguments it creates the default (toolkit) distribution
3151 with the default version (defined in ./prepare).
3153 All Makefile.am files that are subject to the distributions
3154 are now named as Makefile.am.pre. These are ./Makefile.am
3155 and lib/Makefile.am. Others may be changed later.
3157 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3159 * Added invite list, ban list, some key management and connection
3160 error message printing to module formats in the Irssi SILC client.
3162 * Added new silc_client_set_away_message to set the away message
3163 that is back to the person who sent private message. The
3164 affected file lib/silcclient/silcapi.h and the
3165 lib/silcclient/client_prvmsg.c.
3167 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Fixed the private message sending in the Irssi SILC client,
3170 added local command KEY to the Irssi SILC client.
3172 Added key management and key agreement message formats to the
3173 irssi/src/fe-common/silc/module-formats.[ch].
3175 Added USERS (alias WHO) printing, server/router operator
3176 indication and LIST command printing to the module formats.
3178 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3180 * Fixed channel joining notify handling, cumode notify handling
3181 from Irssi SILC client.
3183 * Added SILC specific module-formats to the Irssi SILC client so
3184 that SILC specific message hilighting, colors etc is possible.
3185 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3187 Added channel mode, channel user mode, actions, notices,
3188 whois and whowas printing to the the module-formats.c.
3190 * Fixed a bug in channel deletion in the server. The channel
3191 is not left to the cache even if the channel founder auth mode
3192 is set when there are no users anymore on the channel. Affected
3193 file silcd/server.c.
3195 * The silc_net_localhost now resolves the entire hostname including
3196 the domain name. Affected file lib/silcutil/silcnet.c.
3198 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3200 * Changed the ask_passphrase client operation to be ascynchronous.
3201 It has now a completion callback and a context that the
3202 application must call after it has got the passphrase from
3203 the user. Affected files lib/silcclient/silcapi.h,
3204 lib/silcclient/protocol.c, lib/silcclient/command.c and
3207 Added SilcAskPassphrase callback that the application calls
3208 to deliver the passphrase to the library.
3210 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3211 The public key verification and especially a certificate
3212 verification is asynchronous procedure.
3214 Added new SILC_SKE_STATUS_PENDING status to indicate the
3215 request is pending and a callback will be called to finalize
3218 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3219 indicate that remote end did not send its public key (or
3220 certificate), even though we require it. Added check for this
3221 condition in the SKE. This was a security bug, now fixed.
3223 Defined new SilcSKEVerifyCbCompletion callback that is called
3224 when the verification process is completed.
3226 The affected files lib/silcske/silcske_status.h and
3227 lib/silcske/silcske.[ch].
3229 * Changed the verify_public_key client operation to be async
3230 as well. Defined SilcVerifyPublicKey callback that is used to
3231 indicate the success of the public key verification process.
3233 Changed the server and client to use the new async client
3236 * Changed the Irssi SILC client's internal scheduler to be called
3237 twice as many times as it used to be. As a result the client
3238 should be a bit faster now. Affected file is
3239 irssi/src/silc/core/silc-core.c.
3241 * Added support to Irssi SILC client of asynchronous public key
3242 verification and passphrase inquiry. Affected file is
3243 irssi/src/silc/core/silc-core.c.
3245 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3247 * Do not say "You have left channel %s" in client library.
3248 Moved it to the application. Affected files are
3249 lib/silcclient/command.c and silc/client_ops.c.
3251 * Fixed silc_client_get_clients. Command context was not
3252 duplicated and was freed memory in the callback. Affected
3253 file lib/silcclient/idlist.c.
3255 * Do not say "you are now talking..." on JOIN command in the
3256 client library. The appliation must handle it.
3258 * Do not say ".. changed topic to" in command reply in the
3259 client libary. The application must handle it.
3261 * Fixed TOPIC command sending in the client library.
3263 * Fixed a memory leak in silc_client_command_free in the file
3264 lib/silcclient/command.c.
3266 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3268 * Imported a modified version of Irssi client to the source tree.
3269 The Irssi will be used to create a new client called
3270 Irssi SILC. Imported to irssi/.
3272 Added silc_core_init_finish function to the Irssi. Affected
3273 file irssi/configure.in.
3275 A lot changes in the Makefile.ams around the irssi tree.
3277 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3279 * Do not rehash if the new size is same as the old size of the
3280 hash table, in the silc_hash_table_rehash*. The affected file
3281 lib/silcutil/silchashtable.c.
3283 * Replaced hash_table_del_by_context calls from the server
3284 (when channel->user_list and client->channels) to the
3285 hash_table_del as it is sufficient and faster.
3287 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3289 * Added silc_hash_table_list, silc_hash_table_get and the
3290 SilcHashTableList structure to provide an alternative way to
3291 traverse the hash table. The affected files are
3292 lib/silcutil/silchashtable.[ch].
3294 * Changed the server's idlist routines to use the hash table
3295 routines to optimize the code.
3297 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3299 * Replaced the client entry's `channel' list and channel entry's
3300 `user_list' list to hash tables for optimized lookup. Changed
3301 the code to use the hash table interface around the code.
3302 Affected file lib/silcd/idlist.[ch].
3304 * Added `auto_rehash' boolean argument to the function
3305 silc_hash_table_alloc to indicate whether the hash table should
3306 auto-rehash when it thinks is appropriate time. It will
3307 increase the hash table size if the there is twice as much
3308 entries in the table than the size of the table, and will
3309 decrease the size if there are twice as less entries than
3310 the size of the table.
3312 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3314 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3316 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3318 * silc_idcache_purge_by_context deletes the entry now by context
3319 as it is supposed to do. Affected file lib/silccore/idcache.c.
3321 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3322 client is not anymore valid (WHOWAS givens the info) and not
3323 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3325 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3327 * Removed the `data' and `data_len' arguments from the ID Cache
3328 interfaces and added `name' argument. ID Cache does not handle
3329 anymore the binary data only a names associated with given ID.
3331 * When hashing a Client ID with silc_hash_id the entire ID is
3332 not hashed anymore, instead only the hash of the Client ID is
3333 hashed. This way we can access the Client ID from the cache
3334 with Client ID but with the hash of the ID (which is a hash of
3335 the nickname) as well without any difference in performance.
3337 Added also silc_idcache_find_by_id_one_ext to do one on one
3338 searching when we have the actual ID. Added also function
3339 silc_hash_client_id_compare. The affected files are
3340 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3342 * When hashing the name associated with a ID it is always done
3343 in lowercase. This way we can access the cache without worrying
3344 about case-sensitivity, even though, for example nicknames are
3347 * Fixed a bug in server with channel message sending. It put
3348 wrong ID type as destination ID. The affected file
3349 silcd/packet_send.c.
3351 * silc_idcache_del_by_context now deletes from all hash tables
3352 by context. Affected file lib/silccore/idcache.c.
3354 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3356 * Changed the client library to use the new ID Cache interface.
3357 Changes around the source tree.
3359 * Added silc_hash_table_rehash_ext to rehash with specific
3360 hash function. Affected file lib/silcutil/silchashtable.[ch].
3362 * Added silc_hash_string_compare to compare two strings in the
3363 hash table. Affected file lib/silcutil/silcutil.[ch].
3365 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3367 * Added new function silc_idcache_del_by_context into the
3368 lib/silccore/idcache.[ch].
3370 * Changed the server's ID list routines to use the new ID Cache
3371 interface. Changes around the source tree.
3373 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3375 * Added silc_hash_table_del[_by_context]_ext functions in to the
3376 lib/silcutil/silchashtable.[ch].
3378 Removed silc_hash_table_find_all* routines and added new
3379 silc_hash_table_find_foreach to replace them.
3381 Added silc_hash_table_replace_ext function as extended
3382 replacing function. Separated the simple hash table interface
3383 from the extended hash table interface in the file
3384 lib/silcutil/silchashtable.h.
3386 * Fixed minor bugs and changed it to use some of the new
3387 hash table functions in lib/silccore/idcache.c
3389 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3391 * Added new function silc_hash_table_find_all to return all keys
3392 in the hash table by the specified key. As the hash table is
3393 collision resistant it also makes it possible to have several
3394 duplicate keys in the hash table. This function may be used to
3395 find all of the keys from the hash.
3397 Added user_context arguments to the SilcHashFunction,
3398 SilcHashCompare and SilcHashDestructor to deliver user specified
3401 Added new fuctions silc_hash_table_find[_all]_ext to do
3402 extended lookup with specified hash and compare functions and
3403 specified user contexts.
3405 Added new function silc_hash_table_add_ext to add the key
3406 with specified hash function and user context.
3408 Added new function silc_hash_table_foreach to traverse all
3409 entrys in the hash table. Added SilcHashForeach callback
3412 Added new function silc_hash_table_del_by_context to delete
3413 the entry only if the context associated with the key matches.
3415 Affected files are lib/silcutil/silchashtable.[ch].
3417 * Removed silc_hash_[server/client/channel]_id and added just
3418 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3419 silc_hash_id_compare to compare two ID's using as the hash table
3420 comparison function. Added also silc_hash_data to hash
3421 binary data and silc_hash_data_compare to compare it.
3423 * Removed silc_idlist_find_client_by_hash as it is not needed
3424 anymore. Affected file silcd/idlist.[ch].
3426 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3427 to use internally the SilcHashTable. The new ID Cache is a lot
3428 faster than the old one. Some of the ID Cache interface was also
3429 rewritten and obsolete and stupid functions were removed.
3431 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3433 * Added entry_count field to the SilcHashTable to keep the number
3434 of the entries in the table. Implemented the function
3435 silc_hash_table_rehash. Added new function
3436 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3438 Fixed a minor bug in silc_hash_table_free.
3440 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3441 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3442 into the lib/silcutil/silcutil.[ch].
3444 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3446 * Implemented a collision resistant hash table into the
3447 lib/silcutil/silchashtable[ch]. See the header and the source
3448 for the SilcHashTable API.
3450 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3452 * Merged dotconf version 1.0.2 into lib/dotconf.
3454 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3456 * Do not compile anything in lib/silcsim/* if the SIM support
3457 is not enabled. The tree should now compile without problems
3460 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3462 * Compiled the SILC under cygwin. Compiled and tested briefly
3463 without problems. More tests needed. The SIMs didn't compile
3466 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3468 * Fixed possible crash in silc_get_username in the
3469 lib/silcutil/silcutil.c.
3471 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3473 * Fixed a va_arg in silc/client_ops.c.
3475 * Oops, RC5 routines were named AES and caused some problems
3476 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3478 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3480 * Added new SilcIDIP structure into the lib/silccore/id.h and
3481 replaced the old `ip' fields from all SILC ID's to that type.
3482 This is a step towards IPv6 support.
3484 The silc_id_get_len takes now the ID as an extra argument.
3485 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3486 both IPv4 and IPv6 based ID's.
3488 The affected files are lib/silccore/id.[ch] and other files
3489 around the tree using these routines.
3491 * Removed the ID length arguments in server from various
3492 silc_server_send_notify_* routines -> they are not needed
3495 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3497 * Fixed memory leak in silc_encode_pem_file in the file
3498 lib/silcutil/silcutil.c.
3500 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3502 * Check minor version as well in the SKE. Affected files are
3503 silcd/protocol.c and lib/silcclient/protocol.c.
3505 * Added --identifier option to the server so that an identifier
3506 can be when creating the public key for the server. Affected
3507 file is silcd/silcd.c.
3509 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3510 lib/silccrypt/silcpkcs.c.
3512 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3514 * Register default ciphers and stuff when using -C option with
3515 the server. Affected file sildc/silcd.c.
3517 * Put back the servers public key filename format, it is better
3518 than the new one. For now, the client keys are saved with the
3519 new filename format. The affected file silc/client_ops.c.
3521 * Implemented the Cipher API for the rest of the ciphers that
3522 did not implement it or implemented it the wrong way.
3524 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3526 * Register default ciphers and stuff when using the -S option
3527 in the client. Affected file silc/silc.c. Same also when
3528 creating new key pair with -C option.
3530 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3532 * Fixed the silc_verify_public_key client operation function to
3533 save the public keys differently. The fingerprint is now
3534 used as filename and not the hostname. This way also the
3535 client keys are saved uniquely and not with hostnames. The
3536 affected file is silc/client_ops.c.
3538 * Trimmed the silc_hash_fingerprint function to remove extra
3539 whitespaces from the end of the fingerprint. The affected
3540 file is lib/silccrypt/silchash.c.
3544 * Added silc_cipher_register_default function to register all
3545 default ciphers. It can be used when configuration files
3546 does not exist and the application does not want any specific
3547 ciphers in any specific order.
3549 The SilcDList is now used as silc_cipher_list dynamically
3550 allocated cipher list. Removed the static list all together
3551 and now all ciphers must be allocated to the dynamic list.
3552 The silc_cipher_alloc routine was changed to check only the
3555 All silc_cipher_* routines that used to return int returns
3558 The affected files lib/silccrypt/silccrypt.[ch].
3560 * The same thing was done to silc_hash_* as for silc_cipher_*
3561 routines. Affected files lib/silccrypt/silchash.[ch].
3563 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3564 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3565 Added also silc_pkcs_[un]register[_default] functions.
3566 Removed the data_context from the PKCS API.
3568 * Added silc_hmac_register_default function to register default
3569 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3570 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3571 to unregister all hmacs at once.
3573 * Register the default ciphers, hash functions, PKCSs and HMACs
3574 if client's configuration file does not exist. The affected
3577 * The client did not load the hash functions from the SIM
3578 modules at all. Added support for this. Affected file is
3579 silc/clientconfig.c.
3581 * When decoding public key with silc_pkcs_public_key_decode, check
3582 the supported algorithm only if PKCS are registered. Affected
3583 file lib/silccrypt/silcpkcs.c. The same was done with the
3584 silc_pkcs_private_key_decode.
3586 * Fixed the SILC List routines to keep the list always in order.
3587 It used to change the list's order when traversing the list but
3588 not it preserves the order. Affected file lib/trq/silclist.h.
3590 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3592 * Added the client library to use the SilcSocketConnection's
3593 reference counter (by silc_socket_dup) to prevent the bug that
3594 the socket object may be freed underneath async operation.
3596 * The name resolv library checking fixes in the configure.in.pre.
3599 * Created new version of the protocol drafts for future
3600 development. The -03 drafts are the ones that will be changed
3601 in the trunk now and the -02 will remain as they are.
3603 * Send list of CUMODE notifys to the router when announcing
3604 the channel users to the router. Affected file silcd/server.c.
3605 If the router receiving channel founder CUMODE for a channel
3606 that already has channel founder it will send CUMODE notify
3607 to the sender to remove the channel founder rights from the
3608 announced client. Affected file silcd/packet_receive.c.
3610 * The CUMODE notify may now use Server ID as well as the entity
3611 who changes the mode. Updated protocool specs.
3613 * Updated INSTALL and README files.
3615 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3617 * New web pages in the http://silc.pspt.fi. The pages was
3622 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3624 * Implemented the [DenyConnectin] config section in the server.
3625 Added silc_server_config_denied_conn to check whether incoming
3626 connection is denied. Affected file silcd/serverconfig.[ch].
3628 * Do not check the ports when checking the incoming configuration
3629 data if the port is 0, meaning any. Affected file is
3630 silcd/serverconfig.c.
3632 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * Fixed buffer overflow in silc_string_compare in the file
3635 lib/silcutil/silcutil.c.
3637 * Fixed double free in silc_server_command_leave in the file
3640 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3642 * Fixed the version checking in the server. Affected file is
3645 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3647 * Fixed the configuration data fetching when accepting new
3648 connections in the server. Affected file silcd/server.c.
3650 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Added `sender_entry' argument to the function
3653 silc_server_packet_relay_to_channel so that we can check
3654 whether some destination actually belongs to the same route
3655 the sender belongs (ie, we must not resend the packet to the
3656 sender). Affected file silcd/packet_send.[ch].
3658 * Added `servername' field to the SilcClientEntry in the server
3659 to hold the name of the server where client is from. Affected
3660 file is silcd/idlist.h.
3662 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3664 * Moved the channel message encrypting in the router betwen
3665 router connections from silc_server_channel_message to the
3666 silc_server_packet_relay_to_channel since we want to check
3667 whether we have anybody channel before encrypting anything.
3668 Affected files silcd/packet_[receive/send].c.
3670 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * Fixed the [AdminConnection] server config section to support
3673 multiple entries. Affected file silcd/serverconfig.c.
3675 * Added support into the server to check the validity of the
3676 incoming connection before executing any KE or authentication
3679 * The connection configuration is now saved to the KE and
3680 connection auth protocol contexts and not fetched anymore in
3681 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3683 * The local hosts listenning address and port is also resolved
3684 now when starting the server. We want to have the socket object
3685 to include the real address and port for the listener. Added
3686 new function silc_net_check_local_by_sock into the files
3687 lib/silcutil/silcnet.[ch].
3689 * Fixed a broadcast bug in server -> do not broadcast if we
3692 * Fixed a routing bug. Do not route broadcast packets ever.
3693 Broadcast packets must be processed always and not routed since
3694 they may be destined to some other host than yourself and thus
3695 would get routed without no good reason. Affected file is
3698 * Added function silc_server_config_is_primary_route to check
3699 whether primary router connection has been configured (a router
3700 configuration that we are initiating). If there is not, we
3701 will assume that there is only two routers in the SILC network
3702 and we will use the incoming router connection as our primary
3703 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3705 * Changed the order of the broadcasting. Broadcast _after_ the
3706 packet has been processed not before. Affected file is
3709 * Fixed a [ClientConnection] parsing bug. The port was never
3710 parsed correctly thus resulting to port 0. Affected file
3711 silcd/serverconfig.c.
3713 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3714 argument and did not set the broadcast packet flag. Affected
3715 file silcd/packet_send.c. Fixed same bug in the function
3716 silc_server_send_notify as well.
3718 * If we receive NEW_ID packet for our own ID in the server, ignore
3721 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3725 * Removed the nickname from the Private Message Payload.
3726 Updated the code and the protocol specs.
3728 * Updated protocol specs for submitting to the IETF.
3730 * Tweaked the Random Number Generator a bit. Affected file
3731 lib/silccrypt/silcrng.c. Exported a new function
3732 silc_rng_[global]_add_noise which can be used to add more
3735 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3737 * Do not parse packets with different timeout when protocol
3738 is active -> may cause problem with rekey. Affected file
3741 * When server receives signoff notify it must not create
3742 new channel key if the client is on any channels since the
3743 sender of the signoff notify will create it.
3745 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3747 * Added printing of error messages during SKE protocol from the
3748 failure packet sent by server during SKE. Affected file
3751 * Removed the client's failure_callback handling with timeout
3752 and handle it immediately when received.
3754 * The SKE library returned wrong type in SUCCESS and FAILURE
3755 packets. They must be 32 bit MSB not 16 bit MSB.
3757 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3759 * Ok, rewrote the logic of the re-key and now it seems to work.
3760 I tested it on high traffic with frequent re-keys without
3761 problems. Added hmac_receive (and renamed hmac to hmac_send)
3762 in SilcClientConnection in lib/silcclient/client.h and
3763 in SilcIDListData in silcd/idlist.h. Also, removed the
3764 SilcPacketParserContext's cipher and hmac fields as they are
3765 not needed anymore and actually caused some problems when
3766 the ciphers and hmac's changed underneath the packet parser.
3768 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3770 * If re-key protocol is active then process the incoming packets
3771 synchronously since we must assure that icoming packets encrypted
3772 with the old key is processed before the new keys is set to
3773 use. This is true other packets than for REKEY packets.
3774 Affected file silcd/server.c. The same was done to client library
3775 as well, affected file lib/silcclient/client.c.
3777 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3779 * Fixed bug in client and server to accept the force send if
3780 the packet is send from silc_[server/client]_packet_process
3781 function. Otherwise the packets are never delivered, oops.
3783 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Disable force sending of packets when REKEY protocol is active.
3786 We must assure that no packet is sent directly when rekey is
3787 performed. All packets must be sent through packet queue.
3788 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3789 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3790 function is silc_[server/client]_packet_send_real to check
3793 * Replaced the SIM paths from example config files to
3794 /usr/local/modules. Also, make install creates now
3795 /usr/local/silc/logs directory to hold all the SILC server
3798 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3800 * Made the configure.in.pre work on Solaris. Patch by salo.
3802 * Made all ciphers compatible with non-x86 machines. Defined
3803 CBC mode macros into lib/silccrypt/ciphers_def.h.
3805 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3807 * Fixed the make install.
3809 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3811 * When MAC computation fails the silc_packet_decrypt returned 0
3812 even though it was supposed to return -1. Fixed this. The
3813 affected file is lib/silccore/silcpacket.c.
3815 * Do not replace the config files in /etc/silc (in make install)
3816 if they already exist. Affected file ./Makefile.am.
3818 * Do not send re-key packets immediately but through packet queue.
3819 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3821 * Changed silc_net_check_host_by_sock to return FALSE if the
3822 IP/DNS could not be resolved. Though, it returns the IP address
3823 now even if it could not resolve it (but returns also FALSE).
3824 Affected file lib/silcutil/silcnet.[ch].
3826 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3828 * Added silc_pkcs_decode_identifier to decode the public key's
3829 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3830 Added also silc_pkcs_free_identifier. Added also new context
3831 SilcPublicKeyIdentifier.
3833 * Added -S option to the silc client. It is used to dump the
3834 contents of the specified public key file.
3836 * Changed the PKCS api to return the public key length when
3837 setting the public key.
3839 * Fixed a fatal bug in the public and private key file loading.
3840 Affected file lib/silccrypt/silcpkcs.c.
3842 * Execute the packet parsing for client with zero (0) timeout
3843 if the protocol is active. Affected file silcd/server.c.
3845 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Made the key generation options to the silcd program. Added
3848 -C option, equivalent to client's option.
3850 * Added new [ServerKeys] config section to the server. It
3851 configures the server's public and private key.
3853 * Defined generic Public Key Payload into the protocol
3854 specification to send specific type of public keys and
3857 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3858 public key or certificate.
3860 * Implemented the GETKEY command to the server and to the
3861 client library and on user interface.
3863 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3865 * Made preliminary `make install' work.
3867 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3869 * Added SilcServerRekey context into silcd/idlist.h.
3871 * Added the PFS support as defined in the specification to the
3872 SKE protocol. Affected files lib/silcske/*.c.
3874 * Added `ske_group' field to the SilcServerRekey context to hold
3875 the number of the SKE group that is used with PFS in re-key.
3876 Affected file silcd/idlist.h.
3878 * Added PFS re-key support to the server. Affected file is
3881 * Added silc_protocol_cancel to cancel execution of the next
3882 state of the protocol. Affected file is
3883 lib/silccore/silcprotocol.[ch].
3885 * Added the re-key support with and without PFS to the client
3886 library. Re-key is performed once in an hour, by default.
3888 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3889 Added silc_client_rekey_callback and silc_client_rekey_final.
3890 Affected files are lib/silcclient/protocol.[ch] and
3891 lib/silcclient/client.[ch].
3893 * Removed the `hmac_key' and `hmac_key_len' fields from the
3894 SilcClientConnection structure; not needed. Affected file is
3895 lib/silcclient/client.h.
3899 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3901 * Do not ask whether user wants to use the negotiated private key
3902 for private messages, just use it. Affected file is
3903 silc/local_command.c.
3905 * Added `send_enc_key' and `enc_key_len' fields to the
3906 SilcIDListData structure since they are needed in the re-key
3907 phase. Affected file is silcd/idlist.[ch].
3909 * Implemented the simple re-key protocol into the server.
3910 Affected files silcd/server.c and silcd/protocol.[ch]. The
3911 re-key will be performed once in an hour, by default.
3913 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3914 Added silc_server_rekey, silc_server_rekey_callback and
3915 silc_server_rekey_final.
3917 * Removed Tunneled flag from the protocol. Updated the code
3918 and the specifications.
3920 * Adde `pfs' field to the SilcIDListData to indicate whether
3921 the PFS is to be performed in the re-key. Affected file is
3924 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3926 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3927 int64 of at least the xintXX size. If void * is less that 4
3928 bytes uint32 * will be used. Defined bool as boolean.
3930 * Changed _ALL_ unsigned long and unsigned int to uint32,
3931 unsgined short to uint16 in the source tree.
3933 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3934 not handle clients that has entry->data.registered == FALSE.
3935 They are not in the network anymore. Affected file is
3938 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Implemented the sending of the SERVER_SIGNOFF notify in the
3941 server. Affected file is silcd/server.c.
3943 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3944 Added also silc_notify_payload_encode_args into the
3945 lib/silccore/silcnotify.[ch].
3947 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3948 Affected file silcd/packet_receive.c.
3950 * Implemented the SERVER_SIGNOFF notify handling in the client
3951 library. Affected file lib/silcclient/client_notify.c. Also,
3952 implemnted the printing of the SERVER_SIGNOFF info to the
3953 application. Affected file silc/client_ops.c.
3955 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3956 if the deleting was successful. Affected file silcd/idlist.[ch].
3958 * Added support for public key authentication in the connection
3959 authentication protocol in the client library. Affected file
3960 lib/silcclient/protocol.c.
3962 * Changed the server's silc_idlist_get_clients_by_* interface
3963 to support already allocated array so that new entries may be
3964 added to pre-allocated array. Affected file silcd/idlist.[ch].
3965 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3966 and command replies.
3968 * All command reply functions in the server now calls the
3969 pending command callback even if error occured. This way the
3970 error will be delivered to the client as well. Affected files
3971 silcd/command.c and silcd/command_reply.c.
3973 * Fixed INFO command to return local server's info if no server
3974 was provided. Affected file lib/silcclient/command.c.
3976 * Removed RESTART command for good. Updated the code and the
3979 * Rewrote parts of the task system. It is a bit simpler now.
3980 Removed unsued task priorities. The affected files are
3981 lib/silcutil/silctask.[ch].
3983 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * Moved the USERS printing from the library to the application.
3986 Affected files lib/silcclient/command.c and silc/client_ops.c.
3988 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3992 * Added channel key re-key support. The re-key is perfomed
3993 only by the router and is done once in an hour. Added `rekey'
3994 field to the SilcChannelEntry in the server. Affected files
3995 silcd/server.c and silcd/idlist.h.
3997 * Added silc_task_unregister_by_context into the file
3998 lib/silcutil/silctask.[ch].
4000 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4002 * Added SILC_UMODE_GONE mode to indicate when the client is not
4003 present in the SILC network. Added also support to the local
4004 command AWAY that will set this mode. Added support of showing
4005 "xxx is gone" in WHOIS command. The USERS command shows the
4006 gone status as well.
4008 * Fixed setting server and router operator privileges in the
4009 server's UMODE command. Affected file silcd/command.c.
4011 * Merged the SKE KE1 and KE2 payloads into one payload. The
4012 new KE payload is equivalent to the old KE2 payload.
4014 Cleaned up the SKE Start Payload parsing. It now uses the
4015 simple buffer unformatting to do the parsing. A lot faster
4018 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4019 to the SKE that is used to indicate whether both of the SKE
4020 parties should perform authentication. By default only the
4021 responder performs authentication. By setting this flag also
4022 the initiator must do authentication. By default it is unset
4023 since in normal SKE case, client to server connection, only
4024 the responder should do authentication. When doing SKE between
4025 two clients both should perform authentication. Updated the
4026 code and the protocol specs.
4028 * A little fix to IDENTIFY command in the server. Search the
4029 client first by hash not nickname. Affected file is
4032 * Fixed the silc_client_close_connection to support closing
4033 the client to client connections wihtout deleting too much
4034 data. Affected file lib/silcclient/client.c.
4036 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4037 are received if protocol used to be active but is not anymore
4038 the application would crash due to NULL pointer dereference.
4039 Affected files silcd/server.c and lib/silcclient/client.c.
4041 * Added `hash' field to the SilcClientConnection to include
4042 the hash function negotiated in the SKE protocol.
4044 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4045 to set the channel founder authentication data. A client can
4046 claim the founder rights later by providing the authentication
4047 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4048 This way the channel founder can regain the channel founder
4049 privileges even it is left the channel. This works only on
4050 local server and the client must be connected to the same
4051 server to be able to regain the founder rights. Updated the
4052 protocol specs accordingly.
4054 Added support to the CMODE command in the client to set the
4055 founder auth data. Read the README to see how to set it.
4057 Added support to the CUMODE command to claim the founder
4058 rights. Read the README to see how to do it.
4060 Added support for the founder authentication to the Channel
4061 Entry in the server. Affected file silcd/idlist.h.
4063 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4064 server's CMODE command. Affected file silcd/command.c.
4066 * Added the following new functions into lib/silccore/silcauth.[ch]:
4067 silc_auth_get_method and silc_auth_get_data.
4069 * The server now saves the remote hosts public key to the
4070 SilcIDListData pointer. Affected file silcd/protocol.c.
4072 * The normal server now does not remove the channel entry from
4073 the cache if the founder authentication data is set. It used
4074 to remove it if the founder was the last one on the channel on
4075 the server and left the channel. The auth data is saved and
4076 if the channel is re-joined later the old entry is used with
4077 the old auth data. Affected files silcd/command_reply.c and
4080 * Removed the `pkcs' field from the SilcIDListData structure
4081 in the server; it is not used. Affected file silcd/idlist.h.
4083 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4085 * Fixed packet processing on slow links. Partial packets were
4086 never re-processed because the incoming data buffer was cleared
4087 by the application. Application must not directly clear the
4088 sock->inbuf, the packet processing routines handle it. Fixed
4089 this in client library and in server.
4091 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4093 * Fixed the WHOIS and IDENTIFY send reply function to really
4094 check whether to send list or just one entry. Affected file
4097 * Cleaned up the LEAVE command's channel key distribution. The
4098 affected file silcd/command.c.
4100 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4101 can enforce the channel mode as well. In that case the ID
4102 includes the ID of the server. The code now enforces the
4103 mode change if the router have different mode than the server.
4105 * The notify client operation with CMODE_CHANGE notify can now
4106 return NULL client_entry pointer if the CMODE was not changed
4107 by client. Application must check for this.
4109 * Added <Server ID> argument to INFO command to support server
4110 info fetching by Server ID.
4112 * Added silc_server_announce_get_channel_users to get assembled
4113 packets of channel users of the specified channel. Affected
4114 file silcd/server.[ch].
4116 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4117 was freed underneath the ID Cache.
4119 * Re-announce clients when the server received CHANNEL_CHANGE
4120 notify from the router. Affected file silcd/packet_send.c.
4122 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4124 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4125 crashed since it did not handle the fact that there is no cipher
4126 called "3" and didn't check the error condition. Now fixed.
4128 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4129 flag. It can be used to send message requests.
4131 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * Implemented the RESTART command in the client.
4135 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4136 notice type messages. Added notice printing to the user
4139 * The channel keys are not re-generated if the channel's mode
4140 is PRIVKEY, ie private key on the channel exists. Affected
4141 files silcd/server.c and silcd/command.c.
4143 * Fixed a little bug in channel message delivery when channel
4144 private keys are set in the server. Affected file is
4145 silcd/packet_send.c.
4147 * Changed the setting on channel->on_channel = TRUE from the
4148 silc_client_save_channel_key to the JOIN command reply. The
4149 key payload is not received if the private channel key is set.
4150 Affected file lib/silcclient/command_reply.c and the
4151 lib/silcclient/client_channel.c.
4153 * When the CMODE_CHANGE notify is sent and the channel private
4154 key mode is removed the channel key must be re-generated in
4155 other cells as well. Added this support for the router in the
4156 silcd/packet_receive.c.
4158 * Added new local command NOTICE to send notice message on
4159 channel. Affected file silc/local_command.[ch].
4161 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4163 * Added new local command ME to the client. It is used to send
4164 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4165 some action. Affected file silc/local_command.[ch].
4167 * Changed channel_message and private_message client operations
4168 to deliver the message flags to the application. Added also
4169 the `flags' arguments to the silc_client_send_channel_message
4170 and silc_client_send_private_message functions. Affected file
4173 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4175 * Redefined the Private Message Payload to support private message
4176 keys and to support the new private message flags. Updated
4177 the protocol specs. Flags makes it possible to have for example
4178 CTCP style messages.
4180 * Added new type SilcPrivateMessagePayload and defined an API
4181 for it in the lib/silcclient/silcprivate.[ch].
4183 * Tested private message private keys successfully. Tested the
4184 private message key set, unset and list commands with the new
4187 * Redefined the Channel Message Payload to include the channel
4188 message flags (equal with private message flags) to support
4189 for example CTCP style messages.
4191 * Defined some of the message (for channel and private message)
4192 flags. Updated the protocol specs and added the flags to the
4193 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4195 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4197 * Added SilcKeyAgreementStatus type to the key agreement routines
4198 to indicate the current status and error if one occured.
4199 The status types are defined in the lib/silcclient/silcapi.h.
4201 * Added new local command KEY that is used to set and unset private
4202 keys for channels, set and unset private keys for private messages
4203 with remote clients and to send key agreement requests and
4204 negotiate the key agreement protocol with remote client. The
4205 key agreement is supported only to negotiate private message keys,
4206 it currently cannot be used to negotiate private keys for channels,
4207 as it is not convenient for that purpose.
4209 * Fixed a minor pending callback setting bug in the function
4210 silc_client_get_client_by_id_resolve, now the function works.
4211 Affected file lib/silcclient/idlist.c.
4213 * Added function silc_net_get_local_port to get local bound
4214 port by socket. Added to lib/silcutil/silcnet.[ch].
4216 * Added `sockets' and `sockets_count' fields to the SilcClient
4217 object. They hold the sockets of the listenning sockets in
4218 the client. Listenning sockets may be for example the key
4219 agreement server. Affected file lib/silcclient/client.[ch].
4220 Added functions the silc_client_add_socket and the
4221 silc_client_del_socket. They are exported to the application
4224 * Added ~./silc/clientkeys to support other client's public keys.
4226 * Renamed verify_server_key client operation to verify_public_key
4227 and added one argument to indicate the type of the connection
4228 (server, client etc.).
4230 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4232 * Added silc_server_connection_auth_request to handle the
4233 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4234 silcd/packet_receive.[ch].
4236 * Added silc_server_send_connection_auth_request into the
4237 silcd/packet_send.c to send the connection auth request packet.
4239 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4242 * Fixed the public key authentication in responder side in the
4243 server. The `auth_data' pointer includes the SilcPublicKey
4244 not the path to the public key. Affected file silcd/protocol.c.
4246 * Implemented the public key authentication in the initiator side
4247 in the server. Affected file silcd/protocol.c.
4249 * Removed the [RedirectClient] config section from the server
4250 configuration. Is not needed and I don't want to implement it.
4252 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4254 * Cleaned up the CMODE command in the server. It now works
4255 correctly and supports all the modes defined in the protocol.
4256 Affected file is silcd/command.c.
4258 * Added `hmac_name' field to the SilcChannelEntry in the server
4259 to hold the default HMAC of the channel. It can be set when
4260 creating the channel (with JOIN command). Affected files
4263 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4264 type to indicate the change of the current cipher and hmac
4265 on the channel. Client can safely ignore the <cipher> argument
4266 (if it chooses to do so) since the CHANNEL_KEY packet will
4267 force the channel key change anyway. The <hmac> argument is
4268 important since the client is responsible of setting the new
4269 HMAC and the hmac key into use.
4271 * Fixed the CMODE command in the client library as well.
4273 * Tested CMODE command in router environment successfully.
4275 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4277 * Show the version of the remote client (or server) when connecting
4278 to the server. It is logged to the log file. Affected file
4279 is silcd/protocol.c.
4281 * Fixed the KILLED notify handling in the client library. The
4282 client must be removed from all channels when receiving the
4285 Also, do not remove the client entry when giving the KILL
4286 command but when the KILLED notify is received.
4288 * Removed silc_idlist_find_client_by_nickname from the server.
4289 Not needed anymore. Affected files silcd/idlist.[ch].
4291 * Implemented the CHANNEL_CHANGE notify type handling to the
4292 server. Affected file silcd/server.c.
4296 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4298 * Added silc_server_send_notify_invite to send the INVITE
4299 notify between routers.
4301 * Implemented the INVITE command correctly to the server.
4303 * Implemented the INVITE notify type handling in the server.
4305 * Implemented the INVITE command to the client library and on the
4308 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4310 * Added function silc_server_get_client_resolve to find the
4311 client entry by ID from all ID lists and then resolve it
4312 (using WHOIS) if it cannot be found. Affected file is
4315 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * Implemented the BAN command to the client library.
4319 * The JOIN command in the server now checks the invite list
4322 * Changed the silc_command_reply_payload_encode_va and the
4323 silc_command_payload_encode_va to support that if argument is
4324 NULL it ignores and checks the next argument. Affected file
4325 lib/silccore/silccommand.c.
4327 * Added silc_server_send_notify_ban to send the BAN notify
4328 type between routers.
4330 * Chaned the silc_notify_payload_encode to support that if
4331 argument is NULL it ignores and checks the next argument.
4332 Affected file lib/silccore/silcnotify.c.
4334 * Tested ban lists in router environment successfully.
4336 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4338 * Implemented BAN command to the server, in silcd/command.[ch].
4340 * Removed the BAN and INVITE_LIST modes from the CMODE command
4343 * Added function silc_string_match to regex match two strings.
4344 Affected files lib/silcutil/silcutil.[ch].
4346 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4348 * Redefined parts of the SilcChannelEntry in the server to support
4349 the new ban and invite lists.
4351 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * Redefined the INVITE command. The same command can be used to
4354 invite individuals to the channel but also to manage the invite
4355 list of the channel (to add to and remove from the invite list).
4356 Updated the protocol specs.
4358 * Added new command SILC_COMMAND_BAN that can be used to manage
4359 the ban list of the channel. Updated the protocol specs.
4361 * Removed the channel modes: the SILC_CMODE_BAN and the
4362 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4363 in the CMODE command. The equivalent features are now available
4364 using INVITE and BAN commands. Updated the protocol specs.
4366 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4367 in the network about change in the current ban list. The notify
4368 type is not used by the client.
4370 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4371 support the invite lists.
4373 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4375 * Added new function silc_string_regexify that converts string
4376 including wildcard characters into regex string that can
4377 be used by the GNU regex library. Added into the file
4378 lib/silcutil/silcutil.[ch].
4380 Added silc_string_regex_combine to combine to regex strings
4381 into one so that they can be used as one regex string by
4382 the GNU regex library. Added into the file
4383 lib/silcutil/silcutil.[ch].
4385 Added silc_string_regex_match to match two strings. It returns
4386 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4388 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4390 * Imported GNU regex to the soruce tree into lib/contrib.
4391 Fixed some compiler warning from the regex.c.
4393 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Fixed MOTD command in the server to work in router environment.
4397 * Fixed the MOTD command in the client library to support
4398 the server argument in the command.
4400 * Added `nickname_len' argument to the silc_idlist_add_client
4401 in the server, as the `nickname' argument may be binary data
4404 * Added silc_idlist_get_channels to return all channels from
4407 * Implemented LIST command to the server. Affected file is
4410 * Implemented the LIST command to the client library and on the
4413 * Added [<user count>] argument to the LIST command reply.
4414 With private channels the user count is not shown.
4416 * Updated TODO and README.
4418 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4420 * The client entry's data.registered must be TRUE even with
4421 global client entry on global client list. The data.registered
4422 is used to check whether the client is anymore in the network,
4423 for example with WHOWAS command so it must be valid.
4425 * Fixed the WHOWAS command in the server. It now actually works
4426 in router environment. Added function into silcd/command_reply.c
4427 silc_server_command_reply_whowas_save.
4429 * Added silc_idlist_purge function to the silcd/idlist.c
4430 to periodically purge the ID Cache.
4432 * Fixed INFO command in the server. It works now in router
4433 environment. Added <server name> argument to the INFO command
4434 reply. Updated the protocol specs.
4436 * Fixed minor bug in silc_idcache_purge to not purge if the
4437 expire value is zero.
4439 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4440 they were buggy because of the WHOWAS information.
4442 * Fixed local command MSG to handle the async resolving of
4443 the remote client properly. It used to fail the first MSG.
4444 Affected file silc/local_command.c.
4446 * Added `data_len' field to SilcIDCache context.
4448 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4450 * Update TODO. Todo in commands in the server.
4452 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4454 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4455 used by routers as broadcast packet to inform other routers
4456 about the changed user mode.
4458 Implemented the notify handling in the server. Affected file is
4459 silcd/packet_receive.c. Added the function
4460 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4462 * Added new generic Channel Payload and deprecated the New Channel
4463 Payload. The New Channel Payload is now the generic Channel
4466 * Added new argument `mode' to the silc_server_send_new_channel
4467 as it is required in the Channel Payload now.
4469 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4470 and created a new and real SilChannelPayload to represent the
4471 new generic Channel Payload. Implemented the encode/decode
4472 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4474 * Added silc_server_get_client_channel_list to return the list
4475 of channels the client has joined for WHOIS command reply.
4476 Affected file silcd/server.[ch].
4478 * Implemented the channel list sending in the WHOIS command reply
4479 in server and in the client.
4481 Implemented the channel list displaying on the user interface
4482 as well. Affected file silc/client_ops.c.
4484 * Added silc_channel_payload_parse_list to parse list of Channel
4485 Payloads. It returns SilcDList list of SilcChannelPayloads.
4486 Client for example can use this function to parse the list of
4487 channels it receives in the WHOIS command reply. The caller
4488 must free the list by calling silc_channel_payload_list_free.
4489 Affected files lib/silccore/silcchannel.[ch].
4491 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4493 * Added one new argument <user mode> to the WHOIS command reply
4494 to return the mode of the user in SILC. Updated the protocol
4497 Implemented it to the server and client.
4499 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4501 * Fixed the mode printing on the user interface on joining.
4502 Affected file silc/client_ops.c.
4504 * Implemented the UMODE command and user modes in general to the
4505 client library and to the user interface.
4507 * Implemented the UMODE command to the server.
4509 * The server now sends UNKNOWN_COMMAND error status if client sends
4510 unknown command. Affected file silcd/command.c.
4512 * All server commands now handle the command identifier the right
4513 way when sending the command reply to the client. The client can
4514 use to identify the command replies with the identifier.
4516 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4518 * Added silc_server_get_client_route to resolve the route to
4519 the client indicated by the client ID. Affected file is
4522 * Added silc_server_relay_packet as general function to relay
4523 packet to arbitrary destination. This deprecates functions
4524 like _send_private_message_key, _relay_notify etc. Affected
4525 file is silcd/packet_send.[ch].
4527 Removed silc_server_send_key_agreement,
4528 silc_server_send_private_message_key and
4529 silc_server_packet_relay_notify functions from the file
4530 silcd/packet_send.[ch].
4534 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4535 server. Affected file silcd/packet_receive.[ch].
4537 * Implemented the KILL command to the client. Implemented the
4538 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4539 Affected files lib/silcclient/command[_reply].c and
4540 lib/silcclient/client_notify.c. Implemented the KILL notify
4541 printing in the user inteface.
4543 * Fixed a lot silc_parse_nick memory leaks from the client
4544 library in the file lib/silcclient/command.c.
4546 * Changed the silc_server_send_notify_on_channels's `sender'
4547 argument from SilcSocketConnection to SilcClientEntry to
4548 check the sender as entry and not as connection object and not
4549 to send to the client provided as argument. The affected file
4550 is silcd/packet_send.[ch].
4552 * The notify packets that are destined directly to the client used
4553 to not to be processed by the server. Now changed that and the
4554 server processes all notify packets. After relaying the packet
4555 to the client the notify packet is processed in the server.
4557 * The silc_server_free_client_data now checks whether there is
4558 pending outgoing traffic for the client and purges the data to
4559 the network before removing the client entry.
4561 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4563 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4564 an client is killed from the SILC Network. Updated the protocol
4567 Added new function silc_server_send_notify_killed to the
4568 silcd/packet_send.[ch].
4570 * Added function silc_server_packet_relay_notify to relay notify
4571 packets that are destined directly to a client. In this case
4572 the server does not process the notify packets but merely relays
4573 it to the client. Affected file silcd/packet_send.[ch].
4575 Added also silc_server_packet_process_relay_notify to check
4576 whereto relay the notify. Affected file is
4577 silcd/packet_receive.[ch].
4579 * Implemented the KILL command to the server.
4583 * Added the backup schema desgined last fall to the protocol
4584 specs for everyone to see. The specification is in the
4585 *-spec-xx.txt draft and the packet type definitions for the
4586 backup routers is in *-pp-xx.txt draft. Thusly, added also
4587 new packet type SILC_PACKET_CELL_ROUTERS.
4589 * A big security problem in the implementation discovered. The
4590 signoff of an client did not cause new channel key generation
4591 which it of course should've done. The channel keys must be
4592 always re-generated when client leaves (or signoffs) the channel.
4593 The silc_server_remove_from_channels funtion now handles
4594 the channel key re-generation.
4596 * Added `sender' argument to the silc_server_send_notify_on_channels
4597 to not to send the client provided as argument. Affected file
4598 silcd/packet_send.[ch].
4600 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4602 * Implemented OPER and SILCOPER commands into the server and
4605 * Added silc_auth_verify and silc_auth_verify_data to verify
4606 the authentication directly from the authentication payload.
4607 It supports verifying both passphrase and public key based
4608 authentication. Affected file lib/silccore/silcauth.[ch].
4610 * Added `hash' field to the SilcIDListData structure. It is the
4611 hash negotiated in the SKE protocol. Affected file is
4614 * Slight redesigning of the SilcAuthPayload handling routines.
4615 Do not send SilcPKCS but SilcPublicKey as argument.
4617 * Implemented the public key authentication support to the
4618 serverconfig. The public key is loaded from the provided path
4619 and saved as authentication data to void * pointer. Thus,
4620 changed the unsigned char *auth_data to void *auth_data;
4622 * Fixed SHUTDOWN command to send the reply before the server
4623 is shutdown. :) Affected file silcd/command.c.
4625 * Fixed fatal bug in CONNECT command. The hostname was invalid
4626 memory and server crashed. Affected file silcd/command.c.
4628 * Fixed fatal bug in CLOSE command. The server_entry became
4629 invalid but was referenced later in the command. Affected file
4632 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4634 * Fixed fatal bug in failure packet handling. Server ignored
4635 the failure and thus crashed when it came.
4639 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4642 that the command may be executed only once in (about) 2 seconds.
4643 The old SILC_CF_LAG flag is same but allows command bursts up
4644 to five before limiting.
4646 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4647 server code. Various commands now includes the CF_LAG_STRICT
4648 flag to disallow any kind of miss-use of the command.
4650 * Fixed the silc_buffer_unformat to not to allocate any data
4651 if the length of the data is zero. It used to allocate the
4652 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4654 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4656 * Changed the format of AdminConnection configuration section
4657 in the server. Added username of the admin to the format.
4658 Affected files silcd/serverconfig.[ch].
4660 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4661 to return admin configuration data by host, username and/or
4664 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4666 * Implemented WHOWAS command to the server. Added the functions:
4668 silc_server_command_whowas_parse,
4669 silc_server_command_whowas_send_reply,
4670 silc_server_command_whowas_from_client and
4671 silc_server_command_whowas_from_server
4673 * Added <Client ID> argument to the WHOWAS command reply. Updated
4674 the protocol specs accordingly.
4676 * Implemented WHOWAS command and command_reply to the client
4679 Implemented the WHOWAS printing on the user interface.
4681 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * Added new argument to the WHOWAS command reply, the real name.
4684 It is an optional argument. Updated the protocol specs.
4686 * Added SilcIDCacheDestructor callback that is registered when
4687 the SilcIDCache is allocated. The callback is called when
4688 an cache entry in the ID Cache expires, or is purged from the
4689 cache. Added into lib/silccore/idcache.[ch].
4691 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4692 to destruct the client entries when the cache entry expires.
4693 Other ID Cache's in server and in the client library ignores
4696 * If the ID Cache entry's `expire' field is zero then the entry
4697 never expires. Added boolean `expire' argument to the
4698 silc_idcache_add function in the lib/silccore/idcache.[ch].
4699 If it is TRUE the default expiry value is used.
4701 * Added silc_server_free_client_data_timeout that is registered
4702 when client disconnects. By default for 5 minutes we preserve
4703 the client entry for history - for WHOWAS command.
4705 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4707 * Added support to the server to enforce that commands are not
4708 executed more than once in 2 seconds. If server receives
4709 commands from client more frequently, timeout is registered
4710 to process the commands. Affected file silcd/command.c.
4711 Added new function silc_server_command_process_timeout.
4713 * Changed NICK_NOTIFY handling in client library to check that
4714 if the client's nickname was changed, so there is no need to
4715 resolve anything from the server.
4717 * Removed error printing from the WHOIS and IDENTIFY commands.
4718 If error occurs then it is ignored silently in the client library.
4719 The application, however, may map the received error to
4720 human readable error string. The application currently maps
4721 the NO_SUCH_NICKNAME error to string.
4723 * Made the command status message public to the application. Moved
4724 them from lib/silcclient/command_reply.c to
4725 lib/silcclient/command_reply.h. The application can map the
4726 received command status to the string with the
4727 silc_client_command_status_message function.
4729 * Added check to the server to check that client's ID is same
4730 as the Source ID in the packet the client sent. They must
4733 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4735 * Added dist-bzip hook to the Makefile.am to make bzip2
4736 compressed distributions.
4738 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Server now enforces the maximum length for the nickname and
4741 the channel as protocol specification dictates. 128 bytes for
4742 nickname and 256 bytes for channel name.
4744 * Moved the WHOIS printing to the application. The client libary
4745 does not print out the WHOIS information anymore, the application
4746 must do it. Renamed silc_client_command_reply_whois_print to
4747 the silc_client_command_reply_whois_save.
4749 The client's idle time is also sent to the application now, and
4750 the idle is shown on screen.
4752 * Added silc_client_command_reply_identify_save to save the
4753 received IDENTIFY entries.
4755 * Do not check for channel private keys in message sending and
4756 reception if the channel does not have the PRIVKEY mode set.
4757 Affected file lib/silclient/client_channel.c.
4759 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4761 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4762 just surfaced after chaning the JOIN procedure.
4764 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4766 * Added silc_client_get_clients_by_list to get client entries
4767 from Client ID list, that is returned for example by JOIN
4768 and USERS command replies. The application should use this
4769 function for example when JOIN command reply is received to
4770 resolve the clients already on the channel (library does not
4771 do that anymore as USERS command reply is not used in the JOIN
4772 procedure anymore). Affected files lib/silcclient/silcapi.h and
4773 lib/silcclient/idlist.c.
4775 * JOIN command reply and USERS command reply returns now SilcBuffer
4776 pointers instead of unsigned char pointers when returning
4777 the client list and mode list.
4779 * Added <Client ID> argument to the JOIN command reply, mainly
4780 for the server to identify for which client the command was
4781 originally sent. Updated protocol specs accordingly.
4783 * Added SilcDlist private_key pointer to the SilcChannelEntry
4784 in the client to support the channel private keys. Affected
4785 file is lib/silcclient/idlist.h.
4787 * Added SilcChannelPrivateKey argument to the function
4788 silc_client_send_channel_message so that application can choose
4789 to use specific private ke if it wants to. If it is not provided,
4790 the normal channel key is used, unless private keys are set.
4791 In this case the first (key that was added first) is used
4792 as the encryption key.
4794 * Implemented the support for channel private key handling.
4795 Implemented the following functions:
4797 silc_client_add_channel_private_key,
4798 silc_client_del_channel_private_keys,
4799 silc_client_del_channel_private_key,
4800 silc_client_list_channel_private_keys and
4801 silc_client_free_channel_private_keys
4803 Affected file lib/silcclient/client_channel.c.
4805 * Added the support for the private keys in the channel message
4806 sending and encryption and in the message reception and
4807 decryption. Affected funtions are
4808 silc_client_send_channel_message and silc_client_channel_message.
4810 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4812 * Added SKE's key verify callback to the client library's
4813 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4815 * Removed the statement that server (or router) must send USERS
4816 command reply when joining to the channel so that the client
4817 knows who are on the channel. Instead, the client list and
4818 client's mode list is now sent in the JOIN command reply to the
4819 client who joined channel. This is better solution.
4821 * Added function silc_server_get_users_on_channel and function
4822 silc_server_save_users_on_channel to the silcd/server.[ch].
4824 * Removed function silc_server_command_send_users from the
4827 * Do not show topic on the client library anymore. The topic is
4828 sent in the command reply notify to the application and the
4829 application must show the topic now.
4831 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4833 * Added client searching by nickname hash into the IDENTIFY and
4834 WHOIS commands in the server as they were clearly missing from
4835 them. Affected file is silcd/command.c.
4837 * Fixed a bug in private message receiving in the client library.
4838 The remote ID was freed and it wasn't supposed, now it is
4841 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4843 * Minor fix to the channel payload; allocate the data area, as it
4844 needs to be of specific length.
4846 * If the key agreement port is zero then the operating
4847 system will define the bound port. Affected files are
4848 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4850 * Added new function silc_channel_payload_decrypt into the file
4851 lib/silccore/silcchannel.[ch].
4853 * Moved the channel message etc, check from silc_packet_decrypt
4854 to applications. The library calls now a generic
4855 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4856 when the packet is either normal or special. This was done to
4857 allow more wide range of checking that was not allowed when
4858 the code was in library. Now applications can do virtually any
4859 checks to the packet and return to the library the decision how
4860 the packet should be processed. Affected files are
4861 lib/silccore/silcpacket.[ch].
4863 Added silc_server_packet_decrypt_check to the server and
4864 silc_client_packet_decrypt_check to the client library.
4866 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4867 to send with specified source and destination information.
4869 * Channel message delivery between routers was broken after the
4870 channel key distribution was fixed earlier. The channel key
4871 was used be to distributed to other routers as well which is not
4872 allowed by the protocol. Now this is fixed and channel keys
4873 really are cell specific and the channel message delivery between
4874 routers comply with the protocol specification.
4876 * Fixed various commands in server to check also the global list
4877 for the channel entry and not just the local list. The affected
4878 file silcd/command.c.
4880 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4882 * Added assert()s to buffer formatting and unformatting routines
4883 to assert (if --enable-debug) when error occurs. Affected
4884 file: lib/silcutil/silcbuffmt.c.
4886 * Changed to auto-reconnect to check whether the remote host is
4887 router and register the re-connect timeout if it is. It used
4888 to check that whether we are normal server, but router must do
4889 auto-reconnect with another router as well. Affected file
4892 * Removed the [<key len>] option from CMODE command as the cipher
4893 name decides the key length, nowadays. See the defined ciphers
4894 from the protocol specification.
4896 * Added [<hmac>] option to the CMODE command to define the HMAC
4897 for the channel. Added SILC_CMODE_HMAC channel mode.
4899 * Added [<hmac>] option for the JOIN command so that user can
4900 select which HMAC is used to compute the MACs of the channel
4903 * Added Hmac field to the Channel Message Payload. The integrity
4904 of plaintext channel messages are now protected by computing
4905 MAC of the message and attaching the MAC to the payload. The
4906 MAC is encrypted. Now, it is clear that this causes some
4907 overhead to the size of the packet but rationale for this is that
4908 now the receiver can verify whether the channel message decrypted
4909 correctly and also when private keys are set for the channel the
4910 receiver can decrypt the packet with several keys and check from
4911 the MAC which key decrypted the message correctly.
4913 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4914 lib/silccrypt/silccipher.[ch].
4916 * Added silc_hash_len to return the digest length into the
4917 lib/silcrypt/silchash.[ch].
4919 * Rewrote parts of Silc Channel Payload interface in the
4920 lib/silccore/silcchannel.[ch]. The encode function now also
4921 encrypts the packet and parse function decrypts it.
4923 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4925 * Fixed a minor formatting bug in the SKE's key material processing.
4926 It actually might have processed the keys wrong way resulting
4929 * Redefined the mandatory HMAC algorithms and added new algorithms.
4930 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4931 and hmac-md5 truncated to 96 bits. The mandatory is now
4932 hmac-sha1-96. Rest are optional (including the one that used
4933 to be mandatory). Rationale for this is that the truncated HMAC
4934 length is sufficient from security point of view and can actually
4935 make the attack against the HMAC harder. Also, the truncated
4936 HMAC causes less overhead to the packets. See the RFC2104 for
4939 * Added new [hmac] configuration section. The SKE used to use
4940 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4941 is of course wrong. The official names that must be proposed in
4942 the SKE are the ones defined in the protocol specification
4943 (hmac-sha1-96 for example). The user can configure any hmac
4944 using any hash function configured in the [hash] section. At
4945 least, the mandatory must be configured.
4947 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4949 * Added HMAC list to the SKE proposal list. It has now both
4950 hash algorithm list and HMAC list. This makes the protocol
4951 incompatible with previous versions. The SKE now seems to work
4952 the way it is supposed to work, for the first time actually.
4954 * Defined plain Hash algorithms to the protocol specification.
4957 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4959 * Implemented support for key agreement packets into the server.
4960 Added functions silc_server_key_agreement and
4961 silc_server_send_key_agreement. Other than these functions,
4962 server has nothing to do with this packet.
4964 * Added support for private message key packets into the server.
4965 Added functions silc_server_private_message_key and
4966 silc_server_send_private_message_key.
4970 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4971 called in the protocol's final callback instead in the END
4972 protocol state. This makes a little more sense and in the same
4973 time in client we can use the same protocol routines for normal
4974 key exchange and to key agreement packet handling as well.
4976 * Added to both client's and server's KE protocol context the
4977 SilcSKEKeyMaterial pointer to save the key material. We will
4978 bring the key material to the protocol's final callback by doing
4979 this. The final callback must free the key material.
4981 * Added SKE's packet_send callback into client's KE protocol
4982 context so that the caller can choose what packet sending function
4983 is used. This way we can use different packet sending when
4984 doing normal SKE when doing key agreement packet handling (in
4985 the key agreement packet handling we do not want to encrypt
4988 * Implemented the responder side of the key agreement routines
4989 in the client. The client can now bind to specified port and
4990 accept incoming key negotiation. The key material is passed
4991 to the application after the protocol is over.
4993 * Implemented the processing of incoming Key Agreement packet
4994 in the client. Added function silc_client_key_agreement to
4997 * Implemented the intiator side of the key agreement routines
4998 in the client. The client can now initiate key agreement with
4999 another remote client. The key material is passed to the
5000 application after the protocol is over.
5002 * Created client_keyagr.c to include all the key agreement
5005 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5006 SILC_TASK_CALLBACK except that it is not static.
5008 * Created client_notify.c and moved the Notify packet handling
5009 from the client.[ch] into that file.
5011 * Created client_prvmsg.c and moved all private message and
5012 private message key routines from the client.[ch] into that file.
5014 * Create client_channel.c and moved all channel message and
5015 channel private key routines from the client.[ch] into that file.
5017 * Changed silc_client_get_client_by_id_resolve to resolve with
5018 WHOIS command instead of IDENTIFY command, in the file
5019 lib/silclient/idlist.c.
5021 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5023 * Implemented the SKE's responder side to the Client library.
5025 * When FAILURE is received to the protocol do not trust it
5026 blindly. Register a timeout to wait whether the remote closes
5027 the connection as it should do it, only after that process the
5028 actual failure. This was changed to both client and server.
5030 * Added client_internal.h to include some of the structures
5031 there instead of client.h in lib/silcclient/.
5033 * Added function silc_task_unregister_by_callback to unregister
5034 timeouts by the callback function.
5036 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5038 * Some "Incomplete WHOIS info" errors has been appearing on the
5039 log files. Took away the entry->userinfo check from WHOIS
5040 reply sending. The entry->userinfo is now " " if client did not
5041 provide one. I thought this was fixed earlier but something
5042 is wrong still. Let's see if the error still appears.
5044 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Fixed a minor bug in the login when the channel key is
5047 re-generated in the server. It used to generate the key in
5048 wrong order and thus caused problems in the channel traffic.
5050 * Fixed a minor bug in channel key distsribution after
5051 KICK command. The key was not sent to the router even though
5054 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5056 * Added silc_ske_process_key_material_data as generic routine
5057 to process any key material as the SILC protocol dictates. The
5058 function is used by the actual SKE library but can be used by
5059 applications as well. This relates to the private message keys
5060 and the channel private keys since they must be processed the
5061 same way the normal SILC session keys. The protocol dictates
5062 this. Affected files: lib/silcske/silcske.[ch].
5064 Added also silc_ske_free_key_material to free the
5065 SilcSKEKeyMaterial structure.
5067 * Defined silc_cipher_set_key function to set the key for
5068 cipher without using the object's method function. The affected
5069 files: lib/silccrypt/silccipher.[ch].
5071 * Implemented silc silc_client_add_private_message_key,
5072 silc_client_add_private_message_key_ske,
5073 silc_client_del_private_message_key,
5074 silc_client_list_private_message_keys and
5075 silc_client_free_private_message_keys functions in the
5078 Added functions silc_client_send_private_message_key to send
5079 the Private Message Key payload and silc_client_private_message_key
5080 to handle incoming Private Message Key payload.
5082 * Added Cipher field to the Private Message Key payload to set
5083 the cipher to be used. If ignored, the default cipher defined
5084 in the SILC protocol (aes-256-cbc) is used.
5086 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5088 * Removed lib/silcclient/ops.h file.
5090 Redefined parts of the SILC Client Library API. Created new
5091 file silcapi.h that deprecates the ops.h file and defines the
5092 published Client Library API. Defined also private message key
5093 API and channel private key API into the file.
5095 This is the file that the application must include from the
5096 SILC Client Library. Other files need not be included by
5097 the application anymore.
5099 * Added new key_agreement client operation callback and also
5100 defined the Key Agreement library API for the application.
5102 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5104 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5105 is used by clients to request key negotiation between another
5106 client in the SILC network. If the negotiation is started it
5107 is performed using the SKE protocol. The result of the
5108 negotiation, the secret key material, can be used for example
5109 as private message key.
5111 Implemented the Key Agreement payload into the files
5112 lib/silccore/silauth.[ch].
5114 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5116 * Redefined ciphers for the SILC protocol. Added some new ciphers
5117 and defined the key lengths for the algorithms. Changed the
5118 code accordingly. The default key length is now 256 bits.
5120 * Fixed SKE key distribution function silc_ske_process_key_material
5121 when the key length is more than 128 bits. The default key
5122 length in SILC is now 256 bits.
5124 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5125 to indicate unsupported algorithm.
5127 * Renamed rijndael.c to aes.c and all functions as well.
5129 * Fixed a long standing channel key setting bug in client library.
5130 Weird that it has never surfaced before.
5132 * Fixed bug in channel deletion. If the entire channel is removed
5133 then it must also delete the references of the channel entry
5134 from the client's channel list as the client's channel entry and
5135 the channel's client entry share same memory.
5137 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5139 * Implemented CONNECT and SHUTDOWN commands in the client.
5141 * Implemented CLOSE command to the client.
5143 * Added the function silc_idlist_find_server_by_name into the
5144 files silcd/idlist.[ch].
5146 Added the function silc_idlist_find_server_by_conn into the
5147 files silcd/idlist.[ch].
5149 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5151 * DIE command was renamed to SHUTDOWN. Updated the both code
5154 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5155 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5157 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5160 * Added function silc_server_create_connection function to create
5161 connection to remote router. My server implementation actually
5162 does not allow router to connect to normal server (it expects
5163 that normal server always initiates the connection to the router)
5164 so the CONNECT command is only good for connecting to another
5167 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5169 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5170 or some other client was kicked from the channel.
5172 Implemented the handling of the notify type to both client
5175 Implemented silc_server_send_notify_kicked to send the KICKED
5176 notify. It is used to send it to the server's primary router.
5178 * Implemented the KICK command into server and client.
5180 * Added `query' argument to the silc_idlist_get_client function
5181 to indicate whether to query the client from server or not if
5184 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5185 to indicate that the client is not channel founder.
5189 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Removed the rng context from SilcPacketContext structure and
5192 changed that the packet routine uses the Global RNG API.
5194 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Added support for quit message that client can "leave" on the
5197 channel when it quits the SILC. It is ditributed inside the
5198 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5200 Added silc_server_free_client_data that will take the
5201 signoff message as argument.
5203 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5205 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Updated parts of the protocol specification to keep it up
5210 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5212 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5213 payloads in one packet.
5215 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5216 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5217 use now the new List flag.
5219 * Also deprecated the following packet types: REPLACE_ID,
5220 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5222 * Added list support for Notify packet in server.
5224 * Added silc_server_send_notify_channel_change to send the
5225 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5226 the silc_server_send_replace_id.
5228 * Added silc_server_send_notify_nick_change to send the
5229 NICK_CHANGE notify type. Deprecates the function
5230 silc_server_send_replace_id.
5232 * Added silc_server_send_notify_join to send the JOIN notify type.
5233 Deprecates the function silc_server_send_new_channel_user.
5235 * Added silc_server_send_notify_leave to send LEAVE notify type.
5236 Deprecates the function silc_server_send_remove_channel_user.
5238 * Added silc_server_send_notify_cmode and
5239 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5240 types. Deprecates the silc_server_send_set_mode function.
5242 * Added SERVER_SIGNOFF notify type to indicate that server has
5243 quit. This means that all clients on the channel from that
5244 server will drop. This can be also used when netsplit happens.
5246 Deprecated REMOVE_ID packet type since it is not needed anymore
5249 Added silc_server_send_notify_server_signoff to send the
5250 SERVER_SIGNOFF notify type. Deprecates the function
5251 silc_server_send_remove_id.
5253 Added also silc_server_send_notify_signoff to send the
5254 SIGNOFF notify type.
5256 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5257 SILC protocol from this day on. Changed the protocol
5258 specification as well.
5260 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5261 notify type. It is used between routers to notify about
5262 topic changes on a channel.
5264 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5267 * Partly updated the protocol specification to comply with the
5268 changes now made. It is still though a bit outdated.
5270 * The JOIN notify type now takes one extra argument <Channel ID>.
5271 The packet used to be destined to the channel but now the
5272 JOIN type may be sent as list thus it is impossible to
5273 destine it to any specific channel. By adding this argument
5274 it is again possible.
5276 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5278 * Added CREDITS file. The CHANGES and CREDITS file will appear
5279 in the distribution as well.
5281 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5283 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5284 types in the server's silcd/packet_receive.c.
5286 * Implemented CMODE and CUMODE to work in router environment.
5288 * Fixed minor encoding and decoding buglet from the
5289 lib/silccore/silcmode.c.
5291 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5294 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5296 * Changed all SilcConfigServer* and silc_config_server* to
5297 SilcServerConfig* and silc_server_config*, respectively.
5300 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * Associated the ID (client or server ID) to the Authentication
5303 Payload to avoid any possibility of forging. Updated the
5304 protocol specification and the code accordingly.
5306 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5308 * The RSA key length is now save to the RsaKey context in the
5309 key generation process in lib/silccrypt/rsa.c. The key length
5310 is now used to figure out the maximum size of the block allowed
5311 to be encrypted/signed.
5313 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5314 is equivalent to the silc_mp_mp2bin but does not allocate any
5317 * Changed silc_mp_mp2bin API to take length argument. If it is
5318 non-zero then the buffer is allocated that large. If zero, then
5319 the size is approximated using silc_mp_sizeinbase, which however
5322 * Created Global RNG API which is global RNG that application can
5323 initialize. After initializing, any routine anywhere in the
5324 code (including library) can use RNG without allocating a new
5325 RNG object. This was done to allow this sort of use of the
5326 RNG in code that has no chance to allocate RNG object. All
5327 applications currently allocate this and many routines in the
5328 library use this. Affected file lib/silccrypt/silcrng.[ch].
5330 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5331 it to use the Global RNG API.
5333 * Defined Authentication Payload into protocol specification that
5334 is used during SILC session to authenticate entities. It is
5335 used for example by client to authenticate itself to the server
5336 to obtain server operator privileges.
5338 Implemented this payload into the lib/silccore/silcauth.[ch].
5339 Implemented also routines for public key based authentication
5340 as the new protocol specification dictates.
5342 Moved definitions of different authentication methods from
5343 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5345 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5346 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5347 silc_pkcs_verify_with_hash functions into the file
5348 lib/silccrypt/silcpkcs.[ch].
5350 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5352 * The client entry's userinfo pointer must be always valid.
5353 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5354 will fail since it requires the userinfo. Now, the userinfo
5355 is allocated as "" if actual userinfo does not exist. Actually,
5356 it must exist and it is totally Ok to drop client connections
5357 that does not announce the userinfo. However, we will make
5358 this workaround for now.
5360 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5361 to return the remote port by socket.
5363 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5365 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5366 SILC_SERVER_PENDING_EXEC and added an new macro
5367 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5368 data or when error occurs while processing the pending command.
5370 Added new argument `destructor' into silc_server_command_pending
5371 and to the SilcServerCommandPending object. This destructor is
5372 now called after calling the pending callback or if error occurs
5373 immediately. If error occurs the actual pending callback won't
5374 be called at all - only the destructor. The destructor may be
5375 NULL if destructor is not needed.
5377 All this applies for client library code as well. Similar
5378 changes were made there as well for the pending commands.
5380 In the client, the application must now allocate the
5381 SilcClientCommandContext with the silc_client_command_alloc
5384 * Added reference counter to the SilcServerCommandContext. Added
5385 function silc_server_command_alloc and silc_server_command_dup
5388 Same type of functions added to the client library for the same
5391 * Removed the cmd_ident from IDListData away since it is now
5392 global for all connections. It is the command identifier used
5393 in command sending and with pending commands. The affected file
5396 * Added reference counter to the SilcSocketConnection objecet to
5397 indicate the usage count of the object. The object won't be
5398 freed untill the reference counter hits zero. Currently only
5399 server uses this, and client ignores it. The client must be
5400 set to use this too later. The affected files are
5401 lib/silccore/silcsockconn.[ch]. Added also the function
5402 silc_socket_dup to increase the reference counter.
5404 This was mainly added because it is possible that the socket
5405 is removed underneath of pending command or other async
5406 operation. Now it won't be free'd and proper DISCONNECTING
5407 flags, etc. can be set to avoid sending data to connection that
5408 is not valid anymore.
5410 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5411 the connection. After that it sets SILC_SET_DISCONNECTED.
5412 It is, however, possible that the socket data is not still freed.
5413 The silc_server_packet_process now checks that data is not
5414 read or written to connection that is DISCONNECTED. The socket
5415 get's freed when the reference counter hits zero.
5417 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5419 * Changed the client operation API: channel_message operation's
5420 `sender' is now the client entry of the sender, not the nickname
5421 and the `channel' is the channel entry, not the channel name.
5423 In the private_message operation the `sender' is now also the
5424 client entry of the sender not the nickname.
5426 Affected file is lib/silcclient/ops.h and all applications
5427 using the client operations.
5429 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5431 * Moved the calling of ops->connect() from connect_to_server_final
5432 into receive_new_id functin since that is the point when the
5433 client is actually allowed to send traffic to network. The
5434 affected file is lib/silcclient/client.c.
5436 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5438 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5439 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5440 (if needs broadcasting) instead of broadcasting the packets one
5441 by one which would make a burst in the network traffic.
5443 * Added `broadcast' argument to the functions in silcd/server.[ch]
5444 silc_server_create_new_channel[_with_id] to indicate whether
5445 to send New Channel packet to primary router.
5447 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5449 * Added new function into the silcd/server.[ch] files:
5450 silc_server_create_new_channel_with_id to create new channel with
5451 already existing Channel ID.
5453 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5454 lib/silccore/silcpacket.h. This packet is used t send list of
5455 Set Mode payloads inside one packet. Server uses this to set
5456 the modes for the channels and clients on those channels, that it
5457 announced to the router when it connected to it. The protocol
5458 specification has been updated accordingly.
5460 * The silc_server_new_channel did not handle the packet coming
5461 from normal server as it normally does not send that. However,
5462 when it announces its channels it does send it. Implemented
5463 the support for that.
5465 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5466 into the file lib/silccore/id.h.
5468 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5470 * Fixed memory leaks in the functions silc_idlist_del_client,
5471 silc_idlist_del_channel and silc_idlist_del_server in the file
5472 silcd/idlist.c. All of those leaked like a sieve.
5474 * Fixed some small memory leaks in the client's function
5475 silc_client_notify_by_server.
5477 * Added functions into silcd/server.c: silc_server_announce_clients,
5478 silc_server_announce_channels and silc_server_announce_server.
5479 These functions are used by normal and router server to announce
5480 to its primary router about clients, channels and servers (when
5481 router) that we own. This is done after we've connected to the
5484 These functions effectively implements the following packet types:
5485 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5486 and SILC_PACKET_NEW_ID_LIST.
5488 * Added new functions into the silcd/packet_receive.[ch]:
5489 silc_server_new_id_list, silc_server_new_channel_list and
5490 silc_server_new_channel_user_list to handle the incoming
5491 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5493 * Added support of changing Channel ID in the function
5494 silc_server_replace_id. If the server that announces a channel
5495 to the router already exists in the router (with same name but
5496 with different Channel ID), router is responsible to send
5497 Replace ID packet to the server and force the server to change
5498 the Channel ID to the one router has.
5500 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5501 client that the Channel ID has been changed by the router. The
5502 normal server sends this to the client. Client must start using
5503 the new Channel ID as the channel's ID.
5505 Implemented handling of this new type into lib/silcclient/client.c
5506 into the function silc_client_notify_by_server.
5508 * Added new function silc_idlist_replace_channel_id into the files
5509 silcd/idlist.[ch] to replace the Channel ID.
5511 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5513 * Call silc_server_command_identify_check always when processing
5514 the IDENTIFY command in silcd/command.c
5516 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5518 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5519 send keepalive packets. The packet can be sent by clients,
5520 servers and routers.
5522 Added function silc_socket_set_heartbeat into the file
5523 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5524 If not set, the heartbeat is not performed. The actual
5525 heartbeat is implemented in the low level socket connection
5526 library. However, application is responsible of actually
5529 Added silc_server_send_heartbeat to send the actual heartbeat
5530 packet into silcd/packet_send.[ch]. Server now performs
5531 keepalive with all connections.
5533 * Added silc_task_get_first function into lib/silcutil/silctask.c
5534 to return the timeout task with shortest timeout. There was a bug
5535 in task unregistration that caused problems. TODO has been
5536 updated to include that task system must be rewritten.
5538 * The client library will now resolve the client information when
5539 receiving JOIN notify from server for client that we know but
5540 have incomplete information.
5542 * Rewrote parts of silc_server_remove_from_channels and
5543 silc_server_remove_from_one_channel as they did not remove the
5544 channel in some circumstances even though they should've.
5546 * Encryption problem encountered in server:
5548 The LEAVE command used to send the Channel Key packet to the
5549 router immediately after generating it. However, the code
5550 had earlier sent Remove Channel user packet but not immediately,
5551 ie. it was put to queue. The order of packets in the router
5552 was that Channel Key packet was first and Remove Channel User
5553 packet was second, even though they were encrypted in the
5554 reverse order. For this reason, MAC check failed. Now, this
5555 is fixed by not sending the Channel Key packet immediately but
5556 putting it to queue. However, this is more fundamental problem:
5557 packets that are in queue should actually not be encrypted
5558 because packets that are sent immediately gets encrypted
5559 actually with wrong IV (and thus MAC check fails). So, packets
5560 that are in queue should be encrypted when they are sent to
5561 the wire and not when they put to the queue.
5563 However, the problem is that the current system has not been
5564 designed to work that way. Instead, the packet is encrypted
5565 as soon as possible and left to the queue. The queue is then
5566 just purged into wire. There won't be any fixes for this
5567 any time soon. So, the current semantic for packet sending
5570 o If you send packet to remote host and do not force the send
5571 (the packet will be in queue) then all subsequent packets to the
5572 same remote host must also be put to the queue. Only after the
5573 queue has been purged is it safe again to force the packet
5576 o If you send all packets immediately then it safe to send
5577 any of subsequent packets through the queue, however, after
5578 the first packet is put to queue then any subsequent packets
5579 must also be put to the queue.
5581 Follow these rules and everything works fine.
5583 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Added new function silc_server_remove_clients_by_server to
5586 remove all client entries from ID list when the server connection
5587 is lost. In this case it is also important to invalidate all
5588 client entires as they hold the invalid server entry. This
5589 fixes fatal bug when server has lost connection and will reconnect
5592 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5594 * Made some sanity checks to silc_server_daemonise like to check
5595 whether the requested user and group actually exists.
5597 * Added sanity check to SKE's silc_ske_responder_finish to check
5598 that the public and private key actually is valid.
5600 * Invalidate the client's nickname when receiving Replace ID
5601 packet and the Client ID is being replaced. This means that the
5602 server will query the nickname if someone needs it (client)
5605 * Sort the ID Cache in client library when the ID Cache data
5606 has changed (needs sorting).
5608 * Do not allow for SILC client to create several connections to
5609 several servers. The client does not support windows right now
5610 and generating multiple connections causes weird behaviour.
5612 Irssi-silc client does support windows and can handle several
5613 connections without problems, see: www.irssi.org and SILC plugin.
5615 * Fixed some places where client was added to the IDList. The
5616 rule of thumb is following (in order to get everything right):
5617 If the client is directly connected local client then the
5618 `connection' argument must be set and `router' argument must be
5619 NULL to silc_idlist_add_client function. If the client is not
5620 directly connected client then the `router' argument must
5621 bet set and the `connection' argument must be NULL to the
5622 silc_idlist_add_client function.
5624 * The funtion silc_server_packet_send_local_channel actually did
5625 not check whether the client was locally connected or not. It
5626 does that now. Fixed a bug related to LEAVE command.
5628 * Fixed Remove Channel User payload parsing bug in server's
5629 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5631 * The server's silc_server_save_channel_key now checks also the
5632 global ID list for the channel as it might not be in the local
5633 list. Fixed a bug related to LEAVE command.
5635 * Is this the end of the [<unknown>] buglet that has been lurking
5636 around for a long time? A little for loop fix in server's
5637 silc_server_command_whois_parse that is used by both IDENTIFY
5638 and WHOIS command. At least, this was a clear bug and a cause
5639 of one type of [<unknown>] buglet.
5641 * WHOIS and IDENTIFY commands call the function
5642 silc_server_command_[whois/identify]_check function even if
5643 we are not router server.
5645 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5647 * Added --with-gmp configuration option. If set the GMP
5648 is always compiled in the SILC source tree. If not set then
5649 it is checked whether the system has the GMP3 installed. If
5650 it has then the GMP won't be compiled (the system's headers
5651 and library is used), if it doesn't have it then the GMP is
5652 compiled in the SILC source tree.
5654 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5656 * Changed RSA private exponent generation to what PKCS #1
5657 suggests. We try to find the smallest possible d by doing
5658 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5659 not security fix but optimization.
5661 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5663 * Added new config entry [Identity] to fork the server and run
5664 it as specific user and group. A patch from Bostik.
5666 * Imported Dotconf configuration library into lib/dotconf.
5667 This will be used to create the SILC configuration files later.
5668 It will appear in the distsribution after this commit.
5670 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5672 * A big code auditing weekend happening. Auditing code for
5673 obvious mistakes, bugs and errors. Also, removing any code
5676 Removed files for being obsolete:
5678 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5679 inline in the file lib/silcutil/silcbuffer.h)
5681 o lib/silcutil/silcbufutil.c (the header has inline versions)
5683 Changed code to fix possible error conditions:
5685 o The buffer formatting routines now check that the destination
5686 buffer really has enough space to add the data. This applies for
5687 both buffer formatting and unformatting
5688 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5689 unformatting was changed to accomodate following rules:
5690 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5691 sent to the function while XXX_*STRING will not allocate or copy
5692 the data into the buffer. Instead it sets the pointer from the
5693 buffer into the pointer sent as argument (XXX_*STRING used to
5694 require that the pointer must be allocated already). This change
5695 makes this whole thing a bit more consistent and more optimized
5696 (note that the data returned in the unformatting with XXX_*STRING
5697 must not be freed now). The routines return now -1 on error.
5699 o Tried to find all code that use buffer_format and buffer_unformat
5700 and added return value checking to prevent formatting and
5701 especially unformatting errors and possible subsequent fatal
5704 o Changed ske->x and ske->KEY to mallocated pointers in
5705 lib/silcske/silcske.h. Fixed possible data and memory leak.
5707 o Added return value checking to all *_parse* functions. Fixed
5708 many memory leaks as well.
5710 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5711 so that buffer overflows would not happen. All code now also
5712 checks the return value as it can fail.
5714 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * Added reconnection support to server if the normal server looses
5717 its connection to the router (for example if router is rebooted).
5718 The server performs normal reconnection strategy implemented
5719 to the server. Affected file silcd/server.c.
5721 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5723 * Added new packet type SILC_PACKET_SET_MODE that is used to
5724 distribute the information about changed modes (for clients,
5725 channels and clients channel modes) to all routers in the
5726 network. Updated the protocol specification accordingly.
5728 Added functions into silcd/packet_send.c and
5729 silcd/packet_receive.c: silc_server_send_set_mode,
5730 silc_server_set_mode.
5732 Added new files silcmode.[ch] into lib/silccore that implements
5733 the encoding and decoding of Set Mode Payload. Added new type
5734 SilcSetModePayload. Moved the definitions of different modes
5735 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5737 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5739 * Oops, a little mistake in server's connection authentication
5740 protocol. The protocol is not ended with FAILURE but with
5741 SUCCESS if the authentication is Ok. :) Affected file is
5744 * Implemented NICK_CHANGE notify handling in server in the file
5745 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5746 the local clients on the channel. After the changing nickname
5747 in router environment snhould work and the [<unknown>] nickname
5748 should appear no more.
5750 The silc_server_replace_id function that receives the Replace ID
5751 payload now sends the NICK_CHANGE notify type also in the file
5752 silcd/packet_receive.c
5754 * Changed WHOIS and IDENTIFY command to support the maximum amount
5755 of arguments defined in protocol specs (3328 arguments). This
5756 fixed a bug that caused problems when there were more than three
5759 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Added extra parameter, command identifier, to the
5762 silc_client_send_command so that explicit command identifier
5765 Changed that ID list routines uses specific command identifier
5766 when sending WHOIS/IDENTIFY requests to the server so that they
5767 can be identified when the reply comes back.
5769 Affected files lib/silcclient/command.[ch],
5770 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5772 * Added `sender' argument to silc_server_packet_send_to_channel
5773 to indicaet the sender who originally sent the packet to us
5774 that we are now re-sending. Ignored if NULL. Affected file
5775 silcd/packet_send.[ch].
5777 * Added some server statistics support in silcd/server_internal.h
5778 SilcServerStatistics structure and around the server code. Also
5779 send some nice statistics information when client is connecting
5782 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5784 * Fixed channel ID decoding in server's JOIN command reply in
5785 silcd/command_reply.c
5787 * Fixed braodcasting of replace ID payload to not to send it if
5788 we are standalone server in silcd/packet_receive.c.
5790 * Fixed all channel message sending routines to not to send
5791 packets to clients that has router set, since they are routed
5792 separately in the same function earlier. Affects file
5793 silcd/packet_send.c and all channel packet sending functions.
5795 * In USERS reply, res_argv[i] are not allocated, the table
5796 is allocated. Thus changed that free the table, not its
5799 * In server's whois_check and identify_check if the client is
5800 locally connected do not send any WHOIS commands - they are not
5803 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5805 * Fixed some minor bugs in client when sending WHOIS command. The
5806 arguments was in wrong order.
5808 * Removed statis function add_to_channel from server in
5809 silcd/command.c that was previously used with the joining but
5812 * Tested USERS command in router environment successfully with two
5813 routers, two servers and two clients.
5815 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5817 * Reorganized the USERS command and command reply in client library
5818 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5819 When the command is given by user we register a pending command
5820 callback that will reprocess the command after the reply has been
5821 received from the server. When reprocessing the packet we then
5822 display the information. Thus, the USERS information is displayed
5823 now in the command callback instead of in the command reply
5824 callback. The processing of the command is same as previously
5825 when server has sent the command reply in the JOINing process.
5827 * Added to USERS command in silcd/command_reply.c to join the client,
5828 we didn't use to know about, to the channel after we've created
5829 a client entry for it. Also, for clienet we did know already still
5830 check whether it is on the channel or not and add it if not.
5832 * Removed silc_server_command_join_notify as the function and its
5835 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * Changed the client's pending command handling to the same as the
5838 server's pending command handling. It is also now possible to
5839 execute command reply functions from other command reply
5840 function as the function callbacks for commands and command
5841 replies are one and same. The pending commands are not static
5842 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5843 in client connection context. Thus, pending commands are server
5844 connection specific as it is convenient.
5846 Changed the function silc_client_command_pending and
5847 silc_client_command_pending_del and added new function
5848 silc_client_command_pending_check. Removed the
5849 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5852 * Added cmd_ident, current command identifier, to the client
5853 connection context in lib/silcclient/client.h to keep track on
5854 command identifiers used in command sending. Client's command reply
5855 function handling now supports the mandatory command identifiers.
5857 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5858 funtions in client to fully support pending command callbacks.
5860 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5861 as one of the arguments to the application in the command reply
5864 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5865 before first releasing SILC but came back. Now it is removed again
5866 and should come back nomore. The FORWARDED flag was used only
5867 by the JOINing procedure by forwarding the command packet to router.
5868 Now, the JOINing procedure has been changed to more generic (due
5869 to various router environment issues) and FORWARDED is not needed
5870 anymore for anything. The protocol specification is yet to be
5873 Now, removed silc_server_packet_forward from server and the flag
5874 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5876 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * Renamed NAMES command to USERS command. The NAMES was named that
5879 due to historical reasons. Now it is renamed. Also, rewrote
5880 parts of the USERS command. The nickname list is not sent anymore
5881 by the server. Only Client ID and mode lists are sent in the USERS
5882 command. Changed this also to the protocol specification.
5884 The client now resolves the names and stuff after it receives
5885 the USERS list from the server when joining to the channel.
5887 * WHOIS and IDENTIFY commands has been changed to support multiple
5888 Client ID's per command. One can now search for multiple users
5889 in the network by sending only one WHOIS or IDENTIFY command.
5890 Changed the code and the protocol specifications.
5892 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5893 uses silc_server_command_whois_parse to parse the request. */
5895 * If normal server, do not parse the WHOIS and IDENTIFY requests
5896 before sending it to the router. Saves some time.
5898 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5900 * Fixed JOIN command on client library. Wrong number of arguments
5901 used to crash the client.
5903 * Added silc_server_channel_has_global function to check whether
5904 channel has global users or not.
5906 * Added silc_server_channel_has_local function to check whether channel
5907 has locally connected clients on the channel.
5909 * The silc_server_remove_from_one_channel now checks whether the
5910 channel has global users or not after given client was removed from
5911 the channel. It also checks whether the channel has local clients
5912 on the channel anymore. If it does not have then the channel entry
5913 is removed as it is not needed anymore.
5915 * The silc_server_notify now checks on JOIN notify whether the joining
5916 client is one of locally connected or global. If it is global then
5917 the channel has now global users on the channel and that is marked
5918 to the channel entry. Also, it now saves the global client to
5919 global list who is joining and JOINs it to the channel. This is
5920 for normal server, that is.
5922 Changed silc_server_send_notify_on_channel,
5923 silc_server_packet_relay_to_channel and
5924 silc_server_packet_send_to_channel check if we are normal server
5925 and client has router set (ie. global client) do not send the
5926 message to that client, as it is already routed to our router.
5928 * Implemented LEAVE notify type handling in silc_server_notify
5931 * Tested LEAVE command in router environment successfully. Tested
5932 with two routers, two servers and two clients.
5936 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5938 * Implemented SIGNOFF notify type handling in silc_server_notify
5941 * silc_server_remove_id now removes the client entry from all channels
5942 it has joined and thusly sends SIGNOFF notify type.
5944 * Rewrote the NAMES list generation in server by removing two excess
5945 loops. The lists are created now inside one loop.
5947 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5949 * silc_server_remove_channel_user checks now also global list
5950 for channel and client.
5952 * silc_server_new_channel_user checks now both local and global
5953 list for channel and client. Fixed a bug in client id decoding.
5954 Used to decode wrong buffer.
5956 * silc_server_channel_message checks now both local and global
5957 list for channel entry.
5959 * Tested channel joining (hence JOIN) in router environment
5960 successfully. Tested with two routers, two servers and two
5963 * Tested channel message sending in router environment successfully.
5965 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5967 * Added silc_server_save_channel_key into server.[ch] to save the
5968 received channel key in Channel Key payload processing. It is
5969 also used in JOIN command reply handling.
5971 Equivalent function silc_client_save_channel_key added into
5972 client.[ch] into client library.
5974 * Changed JOIN command reply to send information whether the channel
5975 was created or not (is existing already) and the channel key
5976 payload. Changed protocol specs accordingly.
5978 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5979 the request was sent by ID and not by nickname. Crashed on
5982 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5984 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5985 now correctly save the received data.
5987 * silc_server_free_sock_user_data now notifies routers in the
5988 network about entities leaving the network.
5990 At the same time implemented functions silc_server_remove_id
5991 and silc_server_send_remove_id to receive and send REMOVE_ID
5992 packets. The packet is used to notify routers in the network
5993 about leaving entities. The ID removed will become invalid in
5996 * Added function silc_idlist_del_server into server. Removes and
5997 free's server entry from ID list.
5999 * silc_server_private_message function now checks, if we are router,
6000 that the destination ID really is valid ID, naturally.
6002 * In router when NEW_ID packet is received (for new client) the
6003 hash of the Client ID is saved in the ID Cache but the
6004 client->nickname is set to NULL, instead of putting the hash
6007 IDENTIFY command now also checks that client->nickname must be
6008 valid. If it is not if will request the data from the server who
6009 owns the client. Added new function
6010 silc_server_command_identify_check.
6012 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6013 to set the command to already allocated Command Payload.
6015 * Tested private message sending in router environment with two
6016 routers, two servers and two clients. Fixed minor bugs and now
6019 * Fixed segfault from client's NAMES command. Used to crash if
6022 * Forwarded packets must not be routed even if it is not destined
6023 to the receiver. Changed server code comply with this.
6025 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6027 * Added `require_reverse_mapping' boolean value to ServerParams
6028 structure. If TRUE (not default) the server will require that
6029 the connecting host has fully qualified domain name.
6031 If the reverse mapping is not required and hostname could not be
6032 found the IP address is used as hostname.
6034 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6036 * Implemented version string checking to both client and server.
6037 The check is incomplete currently due to the abnormal version
6038 strings used in development version of SILC.
6040 * Changed all command functions in server to use the new
6043 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6045 * Changed char *data to unsigned char *data in ID Cache system to
6046 support binary data as ID Cache data. Changed code to support
6047 binary data in lib/silccore/idcache.c.
6049 * Renamed silc_server_packet_relay_command_reply to
6050 silc_server_command_reply as it is normal packet receiving
6051 function. Rewrote the function to accept command replys for
6052 servers and not only for clients.
6054 * Mark remote router always as registered server if we are connecting
6055 to it. Otherwise, commands sent by the router to us are ignored.
6057 * All ID List find routines now returns the ID Cache Entry pointer
6058 as well if requested.
6060 * WHOIS command works now in router environment, tested with two
6061 routers, two servers and two clients.
6063 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6064 in router environment (as it is almost equivalent to WHOIS) but
6065 hasn't been tested thoroughly. Added new functions:
6067 silc_server_command_identify_parse
6068 silc_server_command_identify_send_reply
6069 silc_server_command_identify_from_client
6070 silc_server_command_identify_from_server
6072 * Disabled route cache adding because adding two different ID's with
6073 same IP replaces the old cache entry thus giving wrong route.
6074 The entry->router->connection is always the fastest route anyway
6075 so route cache may not be needed. Of course, new routes maybe
6076 established after receiving the ID when the entry->router->connection
6077 might not be anymore the most optimal.
6079 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6081 * Add route cache for received ID for fast routing.
6083 * Added silc_server_packet_route to route received packet on router
6084 that is not destined to us.
6086 * Renamed silc_server_get_route to silc_server_route_get.
6088 * Added id_string and id_string_len fields into SilcServer to
6089 include encoded ServerID for fast comparing without excess
6090 encoding of the ID's.
6092 * Cleaned up WHOIS command on server side. Added following static
6095 silc_server_command_whois_parse
6096 silc_server_command_whois_check
6097 silc_server_command_whois_send_reply
6098 silc_server_command_whois_from_client
6099 silc_server_command_whois_from_server
6101 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6102 arguments in command replies. All command functions should be
6103 updated to use this macro.
6105 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Minor typo fixes on command reply handling on server.
6109 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6111 * Added silc_server_command_add_to_channel internal routine to add
6112 the client to the channel after router has created the channel and
6113 sent command reply to the server.
6115 * Added generic silc_server_send_command to send any command from
6118 * Use static buffer with ID rendering instead of duplicating data.
6120 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6122 * Fixed a channel user mode bug when joining to a channel server gave
6123 everybody channel founder rights, oops.
6125 * We mark ourselves as the router of the incoming server connection
6126 if we are router ourselves. This way we can check in some packet
6127 sending functions whether it is locally connected server. For
6128 incoming router connections we put NULL.
6130 * For router sending packets locally means now always sending the
6131 packet cell wide; to local clients and local servers. For normal
6132 server sending packet locally means sending it to only local
6135 * Fixed the JOIN command to really work in router environment. If the
6136 channel is created it is always created by the router. Router is
6137 also responsible of making the initial joining to the channel,
6138 sending JOIN notify to the sending server and distributing
6139 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6140 does not exist server doesn't do anything else but forward the
6141 command to the router which performs everything.
6143 * Added silc_server_send_channel_key function to send the Channel Key
6146 * Added silc_server_create_channel_key to create new channel key. The
6147 channel key is now re-generated everytime someone joins or leaves
6148 a channel, as protocol dictates. Note: channel->key_len is the
6151 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6153 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6154 packet_receive.[ch] to separate packet sending and receiving
6155 routines. The server.[ch] now includes everything else including
6156 actual packet processing (writing and reading data) and other
6159 Renamed silc_server_private_message_send_internal to
6160 silc_server_send_private_message. The routine is still though
6161 used only to relay private messages as server does not send
6162 private messages itself.
6164 Renamed silc_server_new_channel to silc_server_create_new_channel
6165 and added new function sicl_server_new_channel that handles the
6166 incoming New Channel packet. Added also new sending function
6167 silc_server_send_new_channel to send New Channel Payload.
6169 * Added new function silc_server_notify to process incoming notify
6170 packet to the server/router. Server may then relay the notify
6171 to clients if needed.
6173 * Added new function silc_server_new_channel_user to process incoming
6174 New Channel User packet. Router will redistribute the packet and
6175 send JOIN notify to its local clients and locally connected servers
6176 if needed. Normal server will send JOIN notify to its local client
6177 on same channel when received this packet. Added also corresponding
6178 sending function silc_server_send_new_channel_user to sent the
6181 * Added boolean route argument to send_notif_to_channel and
6182 packet_send_to_channel functions to attempt to route the packet
6183 if it is TRUE and send only locally if it is FALSE.
6185 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6187 * silc_server_replace_id now broadcasts the received replace ID
6188 packet if it is not broadcast packet already. The router must
6189 broadcast to inform other routers about changed ID.
6191 * Added backpointer to server's router into SilcServer context in
6192 silcd/server_internal.h.
6194 * Fixed silc_server_packet_broadcast to send correct broadcast
6197 * The channel key is now distributed to the local client as soon
6198 as it is received from the router (in router environment) so that
6199 no other packet may be sent for the channel until client has
6202 * silc_server_remove_channel_user now broadcasts the received
6203 Remove Channel User packet if it is not broadcast packet already.
6204 The router must broadcast to inform other routers about removed
6207 * Added users field into SilcPacketContext that is a reference count
6208 of the context. One can increase the reference count by calling
6209 silc_packet_context_dup which is now changed to just increase the
6210 reference count instead of duplicating the data. The reference
6211 count is decresed by calling silc_packet_context_free that will
6212 free the data after the reference count hits zero.
6214 For now on the packet context and everything allocated into it
6215 (including the raw packet from network) must be freed by calling
6216 the new silc_packet_context_free function. Added also new function
6217 silc_packet_context_alloc that must be used now to allocate the
6218 context. This also means that if a routine is asynchronous from
6219 silc_[client/server]_packet_parse_type the packet context must
6220 be duplicated by calling silc_packet_context_dup. Otherwise it
6221 gets free'd after silc_[client/server]_packet_parse_type returns.
6222 Also, one must remember that if packet is duplicated then its
6223 reference count must be decresed by calling the free function as
6224 many times as it was duplicated.
6226 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6227 from both client and server.
6229 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6231 * Made joining to a channel working in router environment.
6233 * Cleaned up JOIN command on server side and create function
6234 silc_server_command_join_channel internal routine to make the
6237 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6239 * Changed silc_command_pending list to SilcDList. Also, added
6240 `ident' field to SilcServerCommandPending structure to identify
6241 the reply and to call correct callback.
6243 Added silc_server_command_pending_check function to replace the
6244 corresnponding macro. The silc_command_pending list is not
6247 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6248 to set identifier to previously allocated Command Payload. It
6249 is used to set identifier for command when resending Command
6252 * Added silc_command_payload_encode_payload to encode Command
6253 Payload buffer from SilcCommandPayload structure.
6255 * Added silc_argument_payload_encode_payload to encode Argument
6256 payload buffer from SilcArgumentPayload structure.
6258 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Changed WHOIS command to support router connection on server side.
6261 The whois request is always sent to router unless the server is
6262 standalone server. After server has received the reply from the
6263 router will it send the reply to the client.
6265 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6266 broadcast received broadcast packet. The function is used only
6267 by router. The broadcast packet is always sent to the router's
6270 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6271 render given ID to printable string, for log files for example.
6273 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6275 * Made basic router to router connections working. At least they
6276 can now connect to each other but nothing really works the way
6277 they are supposed - yet.
6279 * Added new initiator token to RouterConnection configuration
6280 file in silcd/serverconfig.[ch]. It is used to tell whether we
6281 are the initiator to the remote router or whether we'll expect
6282 the other end to connect.
6284 * Moved registering of listener task to silc_server_init, hence
6285 the server starts listenning as soon as it is run, even if it
6286 does not have connections to other routers. Let's see how well
6289 * Changed default connection retry timeouts for more suitable in
6292 * Removed cipher and such arguments from silc_idlist_add_client
6293 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6294 Added new function silc_idlist_add_data to add the keys and stuff
6297 * Added SilcIDListData structure and added it to SilcClientEntry
6298 and SilcServerEntry as their first field in the structure. This
6299 way we can explicitly cast the ID entries to the SilcIDListData
6300 structure and get common data for the entries. In past, we had
6301 to first check what type of connection it is and then cast it to
6302 correct ID entry type. Now, we can directly cast the opaque
6303 pointer to the SilcIDListData (no matter what ID entry it actually
6304 is) and get the data needed.
6306 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6308 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6309 in some circumstances even if threre were timeout tasks, though not
6310 IO tasks, but tasks anyway. Now fixed.
6312 * Defined SilcServerConnection structure to hold connection specific
6313 stuff about directly connected servers and routers. The definition
6314 is currently in silcd/server_internal.h. I thought about having
6315 a bit more important role fro this struct but for now it is used
6316 only when connecting to other server (or router actually).
6318 * Added connecting retry support in server when connecting to
6319 router(s). The retry feature implement exponential backoff
6320 algorithm. Also, added SilcServerParams structure to hold default
6321 parameters for server. For now, it include these retry settings
6322 and are hard coded. After server is moded to be as Silc Server
6323 Library this structure will be more important.
6325 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6327 * Changed client librarys channel->clients table to SilcList and
6328 changed code accordingly.
6330 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6332 * Changed client's channel table to SilcList and changed code
6333 accordingly. Also changed SilcChannelClientEntry to include back-
6334 pointer to the channel so that client entry can use that structure
6335 as list as well and we have fast cross-reference to the channel.
6336 This change dramatically decreased the complexity of channel
6337 handling with client entry and vice versa (removed one extra
6338 loop when searching for channel entry from many functions).
6340 * Changed server->sim from table to SilcDList and changed code
6343 * NAMES command can now be used from user interface. It will show
6344 the user list on the channel, neatly.
6346 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6347 Code now saves realname of the user if it becomes available.
6349 * Renamed configure.in to configure.in.pre and made ./prepare
6350 script to automatically add correct version string to
6351 configure.in which it creates from configure.in.pre.
6353 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6355 * NAMES command reply now shows users mode with the nickname when
6358 * Moved silc_client_ch[u]mode[_char] functions from
6359 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6360 place sucks, they are utility functions and should be in some
6363 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6365 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6368 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6372 * Added TRQ (efficient deque and list library) into lib/trq. This is
6373 a very good list library that is currently used in the SILC. Defined
6374 SilcList API over the library because I didn't like the API very
6375 much. See lib/trq/silclist.h for the API and examples of how to
6376 use the API. Fixed various places in the code to use the new
6377 SilcList API. The SilcList is meant for lists that has a structure
6378 already defined as a list. It is not suitable to add just some
6379 context to the list (in TRQ, the context is the list actually).
6381 So, I defined SilcDList that can be used for the purpose where
6382 predefined list structure does not exit. This can be used as
6383 such list. Now some context just can be added to the SilcDList.
6384 Currently this list is not used in the SILC just yet, though there
6385 are a lot places where this can replace dynamically allocated
6386 tables and I will fix these places, later, to use SilcDList.
6387 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6388 and use TRQ internally).
6390 Also fixed some annoying warning messages that the original TRQ
6391 code generated. Also minor changes to TRQ's Makefile.in.
6393 * Added support for querying by Client ID to both WHOIS and
6394 IDENTIFY commands into server, as required by the protocol.
6396 * Removed method function pointers from SilcBuffer structure. They
6397 weren't used to anything and just increased the context size for
6398 no good reason. This change also made silc_buffer_alloc and
6399 silc_buffer_free functions inline functions.
6401 * Disabled command flooding detection support until it's fixed so
6402 that it accepts commands in but does not execute them more than once
6405 * Added silc_net_localhost(), to return local hostname, into
6406 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6407 that must be initialized before calling silc_client_init.
6409 * Added new function: silc_server_send_notify_on_channels to send
6410 notify messages to all channels client has joined. It is assured
6411 that the message is sent only once per client.
6413 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6414 lib/silcutil/silcutil.[ch] as silc_format function. The new
6415 function is generic and is used by server as well, not only by
6416 the logging routines.
6418 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6419 the provided version string was not acceptable. Added new function:
6420 silc_ske_check_version into lib/silcske/silcske.h. The function
6421 must be implemented by the application (client or server) and it
6422 does not reside in the SKE library. The function checks the version
6423 string remote end sent.
6425 * Added back pointers (to opaque context and to SilcSocketConnection)
6426 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6428 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6429 duplicate packet context structure.
6431 * Changed `notify' client operation to send same arguments as client
6432 receives from server except for ID's. ID's are mapped to correct
6433 ID entry and that is returned. Also, if channel entry is not sent
6434 by server but the notify is for channel the channel entry is sent
6435 to application (otherwise application doesn't know that it is for
6436 channel (library gets it from packet's Destination ID)).
6438 * Added silc_client_remove_from_channels into client library to
6439 remove a client from all channels it has joined to. Used when
6440 received SIGNOFF notify from server. Added also new function
6441 silc_client_replace_from_channels to replace old ID entry with
6442 new ID entry on all channels. Used when received NICK_CHANGE
6445 * Fixed ID Cache list handling in silc_idlist_get_client in
6446 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6447 to get (or query) client by ID.
6449 * Updated TODO list.
6451 * Added connection authentication status message defined by the
6452 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6453 support for these into the code in client and server side.
6455 * Added generic function silc_client_send_command to send any command
6456 with variable argument list. Application should use this function
6457 to send commands if the command functions provided by the library
6458 does not suite for the application's user interface needs.
6460 * Added new `failure' client operation. Application is notified about
6461 received failure packet if client is executing a protocol. In this
6462 case the protocol's execution has failed.
6464 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6465 is required by the protocol.
6467 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6468 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6471 * Added status flag to SilcSKE object to indicate realtime status
6472 of the SKE protocol.
6474 * Application receives now exactly same command reply arguments as
6475 the library receives from server. However, if ID is received the
6476 corresponding ID entry is returned to the application (eg. Client
6477 ID is mapped to correct SilcClientEntry entry and that is returned).
6478 Changed command_reply client operation due to this change.
6480 * Changed all ID's in commands and in command replys as ID Payloads.
6481 Change affected both client and server side codes.
6483 All ID's sent in SILC network (with execption of ID's in SILC
6484 Packet header) are sent in ID Payload to support variable length
6487 * Server now notifies nick changes and notifies all clients on
6488 the channels about the new nickname (about the new Client ID,
6491 * Implemented CMODE command to change channel modes. Supports all
6492 channel modes defined by the protocol specs except ban and invite
6493 lists. (Also, private channel key mode is supported but support for
6494 setting private channel key in client is missing, thus, this mode
6495 has no effect on client side (except that server requires that the
6496 client uses private channel key and normal channel traffic does not
6499 Also, invite mode works per se, but INVITE command does not work
6500 yet correctly, so you can set channel as invite only channel but
6501 inviting clients to the channel does not work (it is yet to be
6502 thought what's the best way to do it).
6504 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6505 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6506 Implemented CUMODE command to change user's mode on the channel.
6507 Supports all modes defined by the protocol specs.
6509 * Added NAMES command reply to return users modes on the channel.
6511 * Removed unnecessary and slow ciphers from lib/silccrypt.
6513 * Set SO_KEEPALIVE option to connection sockets by default.
6515 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6517 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6518 redefined the Notify Payload into protocol specs.
6520 * Added silc_id_payload_parse_id to get ID directly from raw
6523 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6525 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6526 accept searching by Client ID as well.
6528 * Added support for LEAVE and SIGNOFF notify types in client library.
6530 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6531 to parse ID Payload from raw data.
6533 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6535 * Added flags parameter into silc_ske_assemble_security_properties
6536 function in lib/silcske/silcske.[ch].
6538 * Changed notify client operation to fit better for notify messages
6539 sent by server. The notify payload received from server is now
6540 passed to the application (after parsing it to SilcNotifyPayload).
6541 It is application's responsibility to retrieve the arguments
6542 from the payload and show the message the way it wants. The message
6543 sent by server is implementation specific.
6545 * Changed public keys to comply with the protocol specification.
6546 Old public keys are not supported anymore and are not compatible.
6548 * Removed nickname from Channel Payload as the latest draft removed
6549 it. The client must resolve the nickname from the NAMES command
6550 reply received when it joined the channel.
6552 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6554 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6556 * Fixed some errors in protocol specification drafts.
6558 * Created lib/silccore/silcnotify.c to implement Notify Payload
6559 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6560 generic payloads described by protocol specifications. The file
6561 includes implementations for ID Payload and Argument Payload.
6563 * Changed Command Payload implementation to use the new Argument
6564 Payload. Changed command_xxxx_payload to command_payload_xxxx
6565 to comply with SILC coding conventions.
6567 * Added suppport for Argument Payload handling in Notify Payload
6568 implementation as protocol requires it. Added the new support
6569 into server and client lib as well.
6571 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6573 * Added support for multiple nicknames on same channel. [n] is
6574 added locally to the nickname if there are more than one same
6575 nicknames on the channel.
6577 * Server now sends all nicknames that matched WHOIS request.
6578 Client also shows the list received from server.
6580 * Added TOPIC command to client side. User can now set and show
6581 current topic on channel.
6583 * Added MOTD command to client and server. Also, server sends the
6584 motd when client connects to the server.
6586 * Changed version strings to comply ISO 8601.
6588 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6590 * Fixed protocol error handling in client library. It should now
6591 cope even if the SKE fails for some reason.
6593 * Made new protocol specification drafts for submitting to IETF.
6595 * Implemented TOPIC command to server in silcd/command.c.
6597 * Added two new notify types into lib/silccore/silcnotify.h:
6598 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6599 notify nickname change and topic setting/change on a channel.
6601 * API change of command_reply operation in client library. The
6602 application gets now the status type received from server as well.
6604 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6606 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6608 * Cras fixed and optimized the packet handling even further and
6609 it should work now. Minor change to the prototype of function
6610 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6612 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6614 * Added new function into lib/silcutil/silcschedule.[ch]:
6615 silc_schedule_with_fd to select() a specified fd. The function
6616 returns after timeout expires or data arrives or goes. The
6617 function is used by packet routines to wait that all data is
6618 received from network.
6620 * Fixed data reading from network in lib/silccore/silcpacket.c.
6621 The code now assures that all data is read from the fd and then
6622 continues packet processing. This was a bug fix since the code
6623 used to drop some data in some circumstances.
6625 * Added new function into lib/silcclient/client.[ch]:
6626 silc_client_start_key_exchange to start key exchange after
6627 connection has been established to server. The code internally
6628 now uses this funtion but its main purpose was to provide it
6629 for applications that perform their own connecting. After
6630 application has created a connection it merely calls this
6631 function to start the key exchange between client and server.
6632 The library takes care of everything else after that.
6634 Updated also lib/silcclient/README to explain the usage of
6637 * Do not send to application information that connection has
6638 been established. Application gets notified it by connect
6641 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6643 * Applied cras's patch to add silc_schedule_one function. The
6644 function runs scheduler once and returns.
6646 * Fixed the scheduler after cras messed it up. The timeout
6647 handling works now as it's supposed to work.
6649 * Added into lib/silccore/ silcnotify.h to include notify
6650 message types support. Changed silc_server_send_notify*
6651 functions, in server.[ch], to support those new notify types.
6652 Added the support for the notify types into client library,
6653 as well. Added new notify client operation into ops.h in
6656 * Changed silc_server_packet_send_to_channel to send normal
6657 packets instead of just channel message packets. The function
6658 is now used to send the notify packets to channels. It is not
6659 used to send channel message packets anymore, as server never
6662 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6663 va_arg()s as it seems to require it nowadays. I guess, if SILC
6664 is compiled with older va_arg() the new code should work anyway.
6666 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6668 * Splitted core library. Core library (lib/silccore) includes
6669 now only SILC protocol specific core (and common) components.
6670 Created new utility library (lib/silcutil) that includes more
6671 generic purpose stuff. The stuff for util library was taken
6672 from the old core library. This was minor and easy split.
6674 * Created SILC Client Library (lib/silcclient) that includes
6675 implementation of the SILC client without user interface. This
6676 was major move from silc/ directory. The code has been changed
6677 so that it is transparent towards the user interface. The
6678 silc/ directory includes now the same user interface as before
6679 and it uses the new client library. Read lib/silcclient/README.
6680 Basicly, the client library performs everything else related
6681 to SILC except user interface handling. Also, configuration
6682 files are considered to be part of user interface and library
6683 does not handle them.
6685 This change also changed a lot of structures, function naming etc.
6686 Most important change was that SilcClientWindow object was
6687 renamed to SilcClientConnection in the client library. Created
6688 also new file lib/silcclient/ops.h. Also added new files
6689 silc/local_command.[ch] and silc/client_ops.[ch].
6691 All these changes were made to make it easier for user interface
6692 designers to create what ever user interface for the SILC client
6695 It is also expected that the server will be moved to lib
6696 directory as well and SILC Server Library will be created;
6697 sometimes in the future.
6699 * Removed Local commands from lib/silccore/silccommand.h as
6700 they are application specific and new client library does not
6701 handle any of those anymore.
6703 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6704 old client implementation in silc/.
6706 * Added support for callback functions in SILC_LOG_* macros.
6707 Application can now set its own callbacks that will be called
6708 instead of using the default functions that will always print
6709 the debug messages to stderr (or stdout). Also, debugging can
6710 now be disabled by setting silc_debug to FALSE and re-enabled by
6711 setting it to TRUE. Note, that logging will still work even
6712 if debugging is disabled.
6714 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6715 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6716 silc_log_reset_debug_callbacks.
6718 * To enable debugging in silc client one must give now -d
6719 option on command line.
6721 * Changed silc_schedule_init to automatically allocate task queues
6722 if they are not allocated before calling it.
6724 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6726 * Added GMP 3.1 into math library.
6728 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6730 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6731 a channel in SILC network. The packet is used by servers and
6732 routers to notify other routers that user has left a channel.
6733 This little feature was missing until now. Added the feature
6734 to protocol specification as well.
6736 Added functions: silc_server_send_remove_channel_user and
6737 silc_server_remove_channel_user into server.[ch].
6739 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6740 lib/silccore/silcpacket.h. However, they are not implemented
6743 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6745 * Fixed joining to a channel and sending channel messages
6746 between server and router. The channel message sending should
6747 now work inside a cell.
6749 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6751 * Fixed the private message sending between server and router.
6752 The private message sending should now work inside a cell.
6754 * Added silc_server_replace_id into server.[ch] to replace
6755 existing ID in the SILC network.
6757 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6758 and silc_idlist_replace_server_id into idlist.[ch] in server.
6760 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6762 * Fixed the server to server connections. Server can again now
6763 connect to router. Router to router connections probably does
6766 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6768 * Added dynamic protocol registering support. Now protocols can
6769 registered and unregistered on the fly. Patch by cras.
6771 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6773 * Added lib/contrib directory to hold routines that some platforms
6774 don't have but are needed by SILC.
6776 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6777 into lin/contrib to provide getopt() and getopt_long() for
6778 those who don't have it.
6780 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6782 * Added AWAY command to client. When away message is set and
6783 client receives a private message packet the client automatically
6784 replies to the sender with the away message.
6786 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6787 bug seemed to be the cause of recent problems when compiling
6790 * Added version detection support to SKE protocol specification
6791 and added the new changes to the SKE implementation as well.
6792 There were other minor changes in the SKE protocol as well.
6794 Many changes in lib/silcske/silcske.[ch] and in
6795 lib/silcske/payload.[ch].
6797 * Added ^U functionality, clear input line. Patch from cras.
6799 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6801 * Mainly small bugfixes on core library. Fixed some debugging
6802 logging and buffer overflow in silclog.c.
6804 * Updated config.sub and config.guess on the distribution tree.
6806 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6808 * Added command lagging support in server. Client may execute
6809 commands now only once in two seconds.
6811 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6813 * Optimized packet reception. MAC computation and checking is now
6814 also more optimized. A lot previously duplicated code is now
6815 used as generic by both client and server.
6817 * Fixed key pair generation in clientutil.c
6819 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6821 * Added into lib/silccore/silcbufutil.[ch] new function;
6822 silc_buffer_realloc.
6824 * Moved generic packet sending/encryption functions to
6825 lib/silccore/silcpacket.[ch] from client and server. Some
6826 rewriting of the functions.
6828 * Moved all generic packet reception/decryption functions to
6829 lib/silccore/silcpacket.[ch] from client and server. The
6830 packet processing is now much cleaner in both client and server.
6831 These were major changes in both client and server.
6833 * Created many common functions in server to do packet sending.
6834 Previously code were duplicated a lot, this has been removed
6837 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6839 * Rewrote major parts of the ID cache system. Don't know
6840 whether it is better now or not but at least the API is more
6843 * Major rewrite on ID cache stuff on client because of the ID
6844 cache API changes. Added idlist.c to client.
6846 * Also major rewrite on ID cache stuff on server as well.
6847 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6848 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6849 in hand, instead they are all put into the ID cache system now.
6850 All server_idlist_* routines uses ID cache now instead of
6851 traversing its own lists (those lists does not exist anymore).
6852 SilcIDList though still exists. Also, SilcXXXEntry's are
6855 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6857 * Finally made the SKE implementation compliant to the protocol
6858 specification. All mp integers are now binary encoded as
6859 opposed being HEX encoded.
6861 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6864 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6865 functions: silc_[encode/decode]_pem. Also added function
6866 silc_encode_pem_file to PEM encode with newlines ('\n') for
6869 * SILC public keys are now encoded either PEM or binary. Same
6870 option is for private keys as well. By default private keys
6871 are binary encoded and public keys PEM encoded. Silly HEX
6872 encoding were removed.
6874 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6875 function to create fingerprints.
6877 * Fixed a bug in SHA1; does not change the original data anymore.
6879 * Partly implemented INFO command on client and server side.
6880 Fixed CLEAR command. Changes to SERVER command; show current
6881 server(s) when giving command without arguments. Added
6882 VERSION command to client.
6884 * Added check to server that unregistered connections cannot
6885 execute commands (unless it is specificly allowed).
6887 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6889 * Fixed screen refresh.
6891 * Fixed channel joining bug from client. On some circumstances
6892 client tried to join to a channel it had already joined.
6894 * Added public key verification process into client's protocol.c.
6895 The client now verifies the public key from user and saves
6896 it into ~./silc/serverkeys/ directory.
6898 Added into: clientutil.[ch]: silc_client_verify_server_key.
6900 * Changed SKE protocol's silc_ske_initiator_finish function
6901 to accept callback function that verifies the received public
6902 key. Removed old silc_ske_verify_public_key function.
6904 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6906 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6907 silc_pkcs_private_key[_data]_set.
6909 * Made the password and public authentication more cleaner in
6910 server's protocol.c.
6912 * Removed historic and obsolete protocol `channel_auth' from
6913 both client and server.
6915 * Removed wrong way of sending command status messages from
6916 server to client in server's command.c. The old way violated
6917 protocol specification.
6919 Changes to silccore/silccommand.[ch]: removed
6920 silc_command_encode_status_payload -> not needed anymore,
6921 changed silc_command_encode_payload_va to accept extra
6922 argument on variable argument list. The argument type must
6923 now be provided to the function. Also, added new function:
6924 silc_command_encode_reply_payload_va which is same as
6925 normal command_encode_payload_va except command status type
6926 is provided as extra argument.
6928 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6930 * Added ~./silc directory handling. The directory includes the
6931 public and private keys for the client.
6933 Added silc_client_check_silc_dir, silc_client_create_identifier
6934 and silc_client_load_keys.
6936 * Implemented SILC protocol compliant public key. Added public
6937 and private key saving to and loading from files.
6939 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6940 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6941 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6942 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6943 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6945 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6946 silc_pkcs_load_[public/private]_key.
6948 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6950 * Added silc_server_get_route (route.[ch]) to get connection
6951 data for the fastest route for given ID.
6953 * Implemented INVITE command on client and server. The command
6954 were re-defined in the SILC Protocol Specification and the
6955 implementation now complies with the specification.
6957 * Implemented PING command on client and server.
6959 * Implemented NAMES command on client and server. The server side
6960 supports currently only normal server not router server yet.
6961 Some changes to NAMES definition in SILC protocol specification.
6963 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6965 * Implemented LEAVE command on client and server.
6967 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6968 again. This change was made to the protocol as well. Server
6969 should not violate the protocol specification anymore.
6971 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6973 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6974 was tested. SOCKS4 was not but should work anyway.
