1 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
4 Affected file lib/silcutil/silcnet.c.
6 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
8 * Fixed a bug in hash table internal routine for traversing
9 the table with foreach callback. The current entry may
10 become invalid in the callback but it was referenced after
11 the callback returned.
13 Do not allow auto rehashing of hash table during the
14 silc_hash_table_foreach operation, for same reasons as it is
15 not allowed for SilcHashTableList. Affected files are
16 lib/silcutil/silchashtable.[ch].
18 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
20 * Defined DLLAPI into silcincludes.h and silcwin32.h for
21 Win32 DLL. extern's in header files are now declared with
24 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
26 * Fixed private message handling. It used some old code that
27 caused the client to crash. Affecte file is
28 lib/silcclient/client_prvmsg.c.
30 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
32 * Added function silc_client_add_channel,
33 silc_client_replace_channel_id, and removed functions
34 silc_client_new_channel_id and silc_idlist_get_channel_by_id
37 * Added cross reference of the joined channels to the
38 SilcClientEntry, and changed the SilcChannelEntry's
39 users list to SilcHashTable. The affected files are
40 lib/silcclient/idlist.[ch].
42 * Fixed a bug in hash table tarversing. While the hash table
43 is traversed with SilcHashTableList the table must not be
44 rehashed. It is now guaranteed that auto rehashable tables
45 are not rehashed while tarversing the list. Also defined that
46 silc_hash_table_rehash must not be called while tarversing
47 the table. Added function silc_hash_table_list_reset that must
48 be called after the tarversing is over. The affected files are
49 lib/silcutil/silchashtable.[ch].
51 * Changed all hash table traversing to call the new
52 silc_hash_table_list_reset in server and in client library.
54 * Added function silc_client_on_channel to return the
55 SilcChannelUser entry if the specified client entry is joined
56 on the specified channel. This is exported to application as
57 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
59 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
61 * Fixed founder regaining problem with JOIN command on normal
62 server. The notify for mode change must be sent always and
63 not only if !cmd->pending. Affected file silcd/command.c.
65 * Fixed the WHOWAS command's reply sending to support the
66 lists correctly. Affected file silcd/command.c.
68 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
70 * When sending JOIN command to router for processing the
71 sender's old command identifier was not saved back to the
72 sender's command context, fixed now. The affected file is
75 * Create the key in JOIN command of the router did not return
76 the channel key, added check for this. Affected file is
79 * Fixed a channel ID update bug in JOIN command reply. Do
80 not directly upgrade the ID but call the function
81 silc_idlist_replace_channel_id if the ID was changed.
82 Affected file silcd/command_reply.c.
84 * Fixed memory leaks from command calling if it would fail.
85 Affected file silcd/command.c.
87 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
89 * Applied patches from cras:
91 Memory leak fixes around libaries, irssi window resize fix,
92 new silclist.h and silcdlist.h, all extern inline changed to
95 * Removed dotconf from lib/dotconf, not needed anymore.
97 * Removed TRQ from lib/trq, not needed anymore.
99 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
100 with server connections. Later this will be configurable
101 in config file after new config file is done. Affected file
104 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
106 * Fixed a crash in server related to channel announcements.
107 Affected file silcd/server.c.
109 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
111 * Fixed memory leaks in silc_server_create_new_channel*
112 functions. Affected file silcd/server.c.
114 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
115 which ID was changed. This way the router will send the
116 user list for the channel again, and server won't be in
117 desync in some rare circumstances. Affected file is
118 silcd/packet_receive.c.
120 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
122 * Check for NULL socket pointer in the function
123 silc_server_packet_send_to_channel_real. Affected file
126 * Fixed the BAN notify handling to correctly remove ban
127 list. Affected file silcd/packet_receive.c.
129 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
131 * Fixed some header addition to Toolkit distribution in
132 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
134 * Added lib/silcclient/client_ops_example.h as an template
135 file for application programmers to quickly start using
136 the SilcClientOperation functions in their application.
137 Updated the lib/silcclient/README as well to tell about this
138 nice file made available.
140 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
142 * Call silc_server_remove_from_channels when removing client
143 entry when NO_SUCH_CLIENT_ID was received. Affected file
144 is silcd/command_reply.c.
146 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
148 * Added server & router operator statistics updating. Affected
149 file silcd/packet_receive.c and silcd/command.c.
151 * Fixed the SERVER_SIGNOFF notify handling on normal server
152 not to save the history information for clients. Same was
153 fixed earlier in remove_clients_by_server function, but not
154 here. Affected file silcd/packet_receive.c.
156 * Raised the default connection-retry count from 4 to 7 in
157 server. Affected file silcd/server.h.
159 * Cancel any possible reconnect timeouts when we start the
160 key exchange. Affected file silcd/server.c.
162 * Do not reconnect on connection failure when SCONNECT was
163 given. Affected files silcd/server.[ch].
165 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
167 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
169 * Fixed the NICK command to always give the unformatted
170 nickname to the one giving the NICK command. If unformatted
171 nickname is cached already it will be formatted and the
172 local entry will always get the unformatted nickname.
173 Affected file lib/silcclient/idlist.c.
175 * Fixed some double frees from client library commands.
176 Affected file is lib/silcclient/command.c.
178 * Fixed CUMODE command in server to assure that no one can
179 change founder's mode than the founder itself, there was a
180 little bug. Affected file silcd/command.c.
182 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
184 * Removed the SilcClientCommandDestructor from the client
185 libary, it is not needed anymore. Affected files are
186 lib/silcclient/silcapi.h, command[_reply].[ch],
187 client_notify, idlist.c.
189 * Fixed GETKEY command to first resolve client, and then
190 resolve the server only if the client was not found, instead
191 of resolving both at the same time. Affected file is
192 lib/silcclient/command.c.
194 * Added silc_client_start_key_exchange_cb and lookup the
195 remote hostname and IP address before starting the key
196 exchange with server. The affected file is
197 lib/silcclient/client.c.
199 * The server's public key is now saved using the IP address
200 of the server and not the servername for the filename.
201 The hostname public key filename is checked as an fall back
202 method if the IP address based filename is not found.
204 Fixed the GETKEY command to save the fetched server key
207 Print the remote server's hostname now when new key is
208 received during connection process. Affected file is
209 irssi/src/silc/core/client_ops.c.
211 * Return always our own public key to the client if it asks
212 for it with GETKEY command. Affected file silcd/command.c.
214 * Removed the use_auto_addr variable from default config
215 file since it was in wrong section. Affected file is
218 * Fixed TOPIC_CHANGE notification to not route it when it
219 was sent using silc_server_send_notify_to_channel function.
220 Affected file silcd/command.c.
222 * Fixed silc_server_send_notify_kicked to send the kicker's
223 Client ID also, it was missing. Affected files are
224 silcd/command.c, silcd/packet_send.[ch].
226 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
228 * Do not save client history information in SERVER_SIGNOFF.
229 Fixes the bug in normal server that it does not detect
230 the client becoming valid after the server becomes back
231 online. Affected file silcd/server_util.c.
233 * Added `sock_error' field into the SilcSocketConnection
234 context. When error occurs during socket operation (read
235 or write) the error is saved. Added also new function
236 silc_socket_get_error to return human readable socket error
237 message. Affected files are lib/silcutil/silcsockconn.[ch],
238 lib/silcutil/unix/silcunixsockconn.c, and
239 lib/silcutil/win32/silcwin32sockconn.c.
241 * The server now prints the socket error message in the
242 signoff for client. Affected file silcd/server.c.
244 * Fixed the `created' channel information sending from router
245 to server in JOIN command. Checks now whether the channel
246 really was created or not and set it according that.
248 Fixed the JOIN command to use the client entry's current
249 ID during the joining procedure instead of the one it sent
250 in the command (it is checked though), since it can change
251 between the packet processing and command processing, and
252 would just case unnecessary pain in the client end. Affected
253 file silcd/command.c.
255 * Fixed a channel key payload sending to use correct channel
256 ID when the server was forced to change the channel's ID by
257 router. Router sent the key payload with the old Channel ID.
258 Affected file silcd/packet_receive.c.
260 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
262 * Call silc_server_save_channel_key only if the key payload
263 was provided in the JOIN command's command reply. Affected
264 file silcd/command_reply.c.
266 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
268 * Fixed silc_mp_sizeinbase to return the value correctly with
269 MPI. Affected file lib/silcmath/mp_mpi.c.
271 * Fixed the stop_server signal to correctly stop the scheduler
272 and gracefully stop the server when SIGTERM or SIGINT signals
273 are received. Affected file silcd/silcd.c.
275 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
277 * Simple handling of TERM and HUP signals. Also added some log
278 flushing call around. Affected file is
281 * Fixed small bugs in silclog.c. Now buffering output will take
282 effect after 10 seconds since startup: This will ensure that
283 no important startup messages are lost. Also output redirection
284 will preserve original format ([Date] [Type] message).
285 Affected file is lib/silcutil/silclog.c.
287 * Added two options to the config file, in the logging section:
288 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
289 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
291 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
293 * Do not print the warning about log files not being initialized
294 more than once to avoid excess logging. Affected file is
295 lib/silcutil/silclog.c.
297 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
298 the SIM copying in make install in Makefile.am.pre.
300 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
302 * Rewritten silclog APIs. Globally interesting changes follows:
303 silc_log_set_files() changed to silc_log_set_file().
304 silc_log_set_callbacks() changed to silc_log_set_callback().
305 ROBOdoc documented silclog header file.
306 SilcLogCb now returns bool to wether inihibit the default
307 handler or not (to keep the old behaviour return always TRUE).
308 The new APIs should also fix the problem of the
309 silcd_error.log file that was written in the current directory.
312 Log files streams will remain opened after silc_log_set_file()
313 call, means less CPU usage notably on high traffic servers.
314 File streams are now full buffered, and flushed to the disk
315 every 5 minutes, lesses HD activity and CPU usage.
316 Messages can be redirected, allowing admins to configure
317 one single logfile for all server messages.
318 the silc_log_quick global variable to activate fast-logging.
319 Affected files lib/silcutil/silclog.[ch]
321 * Changed some code to conform new silclog APIs. Affected
322 files are doc/example_silcd.conf.in, silcd/server.c
323 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
326 * Fixed a memory leak that could occur in some situations.
327 Affected file silcd/serverconfig.c.
329 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
331 * Added the silc_client_del_client to remove the client from
332 all channels as well. Affected file lib/silcclient/idlist.c.
334 * Fixed the client library to correctly remove the client
335 from all channels when the client entry is being destroyed.
336 Affected file lib/silcclient/client_notify.c, command.c.
338 * Added auto-nicking support to the client library. If the
339 applicatio now sets client->nickname it will be sent to the
340 server after connecting by the library. This way for example
341 SILCNICK (or IRCNICK) environment variables will have effect
342 and always change the nickname automatically to whatever
343 it is wanted. Affected file lib/silcclient/client.[ch].
345 * Renamed silc_server_command_bad_chars to the
346 silc_server_name_bad_chars and moved it to the
347 silcd/server_util.[ch]. Added also new function
348 silc_server_name_modify_bad to return nickname that
349 includes bad characters as new nickname without those
350 bad characters. This check and modify is now used in
351 silc_server_new_client when the username is initially set
352 as nickname, so it must be checked to be valid nickname.
353 Affected file silcd/packet_receive.c.
355 * The nickname length is now taken from the packet for real
356 and not trusted to strlen() since it clearly can return
357 wrong length for nickname including bad characters. This
358 also applies to channel names. Affected file silcd/command.c.
360 * Removed the lib/silcsilm/modules directory. Modules are now
361 compiled into the lib/silcsim. Fixed the copying of the
362 modules to follow symbolic links in Makefile.am.pre.
364 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
366 * Fixed silc_string_regexify list creation. Fixes bugs with
367 BAN and INVITE commands in server. The affected file is
368 lib/silcutil/unix/silcunixutil.c.
370 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
372 * Removed the command destructor entirely from the server's
373 command and command reply routines. It is not needed, and
374 its usage was buggy and caused crashes. Affected files are
375 silcd/command[_reply].[ch].
377 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
379 * Cancel protocol and NULL sock->protocol if timeout
380 occurred during protocol. Affected file silcd/server.c.
382 * Cancel protocol timeouts always before calling the final
383 callback, to assure that after final callback is called
384 no other state will be called for the protocol anymore.
385 Affected file silcd/protocol.c.
387 * Print error log if incoming connection configuration could
388 not be found. Affected file silcd/server.c.
390 * Fixed JOIN command to correctly save the founder mode
391 to the client on normal SILC server, when the channel
392 was created by the router. Affected file silcd/command.c.
394 * Fixed LIST command (hopefully) to send correct reply
395 packets. Affected file silcd/command.c.
397 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
399 * The silc_packet_receive_process now returns FALSE if the
400 read data was invalid packet, and TRUE if it was ok.
402 The server now checks that if unauthenticated connection
403 sends data and its processing fails the server will close
404 the connection since it could be a malicious flooder.
406 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
408 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
410 * Make sure the warning about error opening a log file is
411 printed only once and not everytime it fails (produces
412 too much useless log). Affected file lib/silcutil/silclog.c.
414 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
416 * Made the silc_server_daemonise() function more readable.
417 Affected file silcd/server.c.
419 * Pid file is now optional, the user may comment it out from
420 the config file. Removed define SILC_SERVER_PID_FILE, we
421 don't need a default any longer. Affected file
422 configure.in.pre, lib/Makefile.am.pre.
424 * Make some use of the pid file. The server now dies at startup
425 if it detects a valid pid file on his path. The server would
426 die anyway in this circumstance, because of the bind() failure.
427 Affected file silcd/silcd.c.
429 * No longer compiling lib/dotconf.
431 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
433 * Fixed JOIN command parsing not to crash. Affected file
434 lib/silcclient/command.c.
436 * Fied the NICK_CHANGE notify to add the new client entry
437 even it is resolved. This removes an <[unknown]> nick
438 thingy bug in the client. Affected file is
439 lib/silcclient/client_notify.c.
441 * Do not try to allocate 0 bytes (efence does not like it)
442 in lib/silccore/silccomand.c when encoding payload.
444 * Do not take IRCNICK as nickname in Irssi SILC client since
445 it is not possible to set nickname before hand connecting
446 the server (TODO has an entry about adding auto-nicking
449 * Changed the silc_server_command_pending to check whether
450 there already exists an pending entry with the specified
451 command, command identifier and pending callback. This is
452 to fix IDENTIFY and WHOIS related crashes that may register
453 multiple pending commands with same identifier. Affected
454 file silcd/command.c.
456 * Fixed the server to reconnect to the router even if it
457 was already reconnecting and EOF was received. This to
458 fix a possibility that the server wouldn't ever try to
459 auto-reconnect to the router. Affected file silcd/server.c.
461 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
463 * Fixed the server's password authentication to use the
464 length of the locally saved password, and not the one
465 sent in the packet. Affected file silcd/protocol.c.
467 * Fixed same password authentication problem in the
468 Authentication Payload handling routines in
469 lib/silccore/silcauth.c.
471 * Yet another password authentication problem fixed with
472 channel password handling in silcd/command.c.
474 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
476 * If first character of string in silc_parse_userfqdn is '@'
477 then do not parse it. Affected file is
478 lib/silcutil/silcutil.c.
480 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
482 * Fixed minor bug in IDENTIFY command reply sending, which
483 caused various weird problems during JOIN when it was
484 resolving names for users. Affected file silcd/command.c.
486 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
488 * Fixed the IDENTIFY command reply sending to chech better valid
489 clients. It was possible to send incomplete list of replies.
490 Affected file silcd/command.c.
492 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
494 * Added silc_client_command[s]_[un]register functions now to
495 dynamically register the commands in client library. Removed
496 the static table of commands. This allows the client library
497 to call commands without causing the application to know about
498 what commands library has called.
500 Removed the INFO command reply kludge to detect when the command
501 was called by library. Now library use its own command reply
502 function for INFO command.
504 Added function silc_client_command_call to call a command.
505 Application can use it to call command, not access the structure
508 Now all commands that are sent by the client library (not
509 explicitly sent by application) use own command reply functions.
511 Affected files around lib/silcclient/ and in
512 irssi/src/silc/core/.
514 * Fixed the WHOIS command reply sending to chech better valid
515 clients. It was possible to send incomplete list of replies.
517 Fixed the WHOIS and IDENTIFY to send the request to router
518 if normal server did not do it and did not find any results.
520 Affected file silcd/command.c.
522 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
524 * Moved the internal data from SilcClient context into its
525 own file, not accesible to application. Affected files
526 lib/silcclient/client.h and lib/silcclient/client_internal.h,
527 and other files in client library.
529 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
531 * Added doc/examples installation target in Makefile.am.pre.
534 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
536 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
537 commands the found client entry will be removed from the
538 cache, after notifying application about the error. Affected
539 file lib/silcclient/command_reply.c.
541 * Changed the /MSG to check for exact nickname user gave, and
542 not let `nick' match `nick@host' if it is only one found. Now,
543 user must type the exact nickname (like nick@host2) even if
544 there are no more than one same nicks found. This is to avoid
545 a possibility of sending nickname to wrong nickname since
546 `nick' could match `nick@host'. Affected file is
547 irssi/src/core/silc-servers.c.
549 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
551 * Do not print "you are now server operator" or similar when
552 giving /away command. Affected files are
553 irssi/src/silc/core/client_ops.c, silc-servers.h.
555 * Made the silc_server_command_pending_error_check to send
556 the same command reply payload it received back to the
557 original sender of the command. This way all arguments
558 that was received by the server will be received by the
559 client too. Affected file silcd/command.c.
561 * Added the silc_idcache_add to return the created cache entry
562 to a pointer. Affected file lib/silccore/silcidcache.[ch].
564 * Add global clients to expire if they are not on any channel.
565 This is because normal server will never know if they signoff
566 if they are not on any channel. The cache expiry will take
567 case of these entries. This is done by normal servers only.
568 The affected files are silcd/command_reply.c,
569 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
571 * If server receives invalid ID notification for WHOIS or
572 IDENTIFY and the ID exists in the lists, it is removed.
573 Affected file silcd/command_reply.c.
575 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
576 in client then client entry that it matches is searched and
577 the nickname is printed on the screen for user. Affected
578 file irssi/src/silc/core/client_ops.c.
580 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
582 * Use cache entry expire time in the LIST command reply to
583 purge old entries from the cache after the LIST command
584 reply has been received. This way we don't have non-existent
585 entries in the cache for too long. Affected file is
586 silcd/command_reply.c.
588 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
590 * If we are normal server, and we've not resolved client info
591 in WHOIS or IDENTIFY from router, and it is global client,
592 we'll check whether it is on some channel. If it is not
593 then we cannot be sure about its validity and will resolve it
594 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
595 file silcd/command.c.
597 * Search channel by name (if possible) rather than by ID
598 in IDENTIFY command's command reply. Affected file is
599 silcd/command_reply.c.
601 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
603 * Distribute to the channel passphrase in CMODE_CHANGE notify.
604 Updated specs and implemented it. Affected file silcd/command.c,
605 silcd/packet_send.c and silcd/packet_receive.c.
607 * Implemented the <founder auth> payload handling in the JOIN
608 command. If provided all conditions for channel joining
609 except requirement to provide correct passphrase can be
610 overrided by the channel founder. Updated the protocol specs.
611 Affected file silcd/command.c.
613 Added support for founder auth in JOIN command in client
614 library. Fixed the parsing of the JOIN command now to support
615 all options as they should be. The affected file is
616 lib/silcclient/command.c.
618 * Optimized the WHOIS and IDENTIFY commands to send the request
619 to router only if it includes nicknames or other names. If
620 they include only IDs then check the local cache first before
621 routing. Affected file is silcd/command.c.
623 * Added channels topic announcements. Affected file is
624 silcd/packet_receive.c and silcd/server.c.
626 * Fixed the silc_server_send_notify_topic_set to really destine
627 the packet to channel. Affected file silcd/packet_send.c.
629 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
630 library. Affected file lib/silcclient/client_notify.c.
632 * Added UMODE announcements. Affected file silcd/server.c.
634 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
636 * Memory leak fixes in:
638 lib/silcutil/silcsockconn.c
639 lib/silcske/silcske.c
642 lib/silccrypt/silcpkcs.c
643 lib/silccore/silccommand.c
644 lib/silccore/silcidcache.c
649 * ROBOdoc documented the lib/silcske/groups.h file and a
650 bit changed the interface for better.
652 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
654 * Update the client entry context in the ID cache after
655 nick change. Affected file lib/silcclient/command.c.
656 Fixes the CUMODE command when regaining founder privileges,
657 and a little WHOIS problem.
659 * Fixed silc_net_gethostbyname to correctly call the
660 inet_ntop. Affected file lib/silcutil/silcnet.c.
662 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
664 * Added IPv6 support checking to the configure.in.pre, added
665 also --enable-ipv6 option to override the check. Affected
666 file configure.in.pre.
668 * The silc_thread_create now calls the start function
669 directly if threads support is not compiled in. Removes
670 ugly #ifdef's from generic code. Affected files are
671 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
673 * Added silc_net_gethostby[name/addr]_async to asynchronously
674 resolve. Affected files are lib/silcutil/silcnet.[ch].
676 * Added support for rendering IPv6 based server, client and
677 channel IDs. Affected file lib/silcutil/silcutil.c.
679 * Added support for creating IPv6 based server IDs. Affected
680 file is silcd/serverid.c.
682 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
684 * Added silc_net_gethostby[addr/name] into the
685 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
686 routines. Added silc_net_is_ip[4/6]. Affected file is
687 lib/silcutil/unix/silcunixnet.c. All routines that take
688 address as argument now supports both IPv4 and IPv6 addresses.
690 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
692 * Fixed LIST command reply sending in server. Affected file
695 * Server now sends the kicker's client ID in the KICK notify
696 to the kicked client. Affected file silcd/command.c.
698 * The client library now parses the kickers client ID and
699 UI displays it. Affected files lib/silcclient/client_notify.c
700 and irssi/src/silc/core/silc-channels.c, module-formats.c.
702 * Made all payload parsing function prototypes consistent.
703 They all take now const unsigned char * and uint32 pair as
704 the payload data instead of SilcBuffer. Changes all around
705 the source tree. Other unsigned char* -> const unsigned char*
706 changes around the tree as well.
708 * Optimized SFTP client and server packet sending not to
709 allocate new buffer for each packet but to recycle the
710 first allocated buffer. Affected files are
711 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
713 * Optimized the SFTP client to use SilcList instead of
714 SilcDList for requests, because it is faster. Affected file
715 is lib/silcsftp/sftp_client.c.
717 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
718 into lib/silccore/silcid.[ch].
720 Renamed silcpayload.[ch] into silcargument.[ch].
722 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
724 * If client entry is deleted with active key agreement
725 session, abort the session.
727 The silc_client_abort_key_agreement now calls the completion
728 callback with new SILC_KEY_AGREEMENT_ABORTED status.
730 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
733 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
735 * Don't use __restrict in older GCC's. Affected file is
736 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
738 * silc_net_localhost now attempts to reverse lookup the
739 IP/hostname. Affected file lib/silcutil/silcnet.c.
741 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
742 command. It can be used to gain founder privileges at
743 the same time when joining the channel.
745 Defined that the SILC_NOTIFY_TYPE_KICKED send the
746 kicker's client ID as well. Updated protocol specs.
748 Defined that the server must send SILC_COMMAND_IDENTIFY
749 command reply with error status to client who sent
750 private message with invalid client ID.
752 Updated the protocol specification.
754 * Added silc_server_send_command_reply to send any
755 command reply. Affected file silcd/packet_send.[ch].
757 * Added silc_id_payload_encode_data to encode ID payload
758 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
760 * The server now send IDENTIFY command reply with error
761 status if client ID in private message is invalid. Affected
762 file silcd/packet_receive.c.
764 * Save the server key file with server's IP address in
765 the filename instead of hostname. The affected file is
766 irssi/src/silc/core/client_ops.c.
768 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
770 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
773 * Added libtool support for compiling shared objects in
774 lib/silcsim. Affected file configure.in.pre and
775 lib/silcsim/Makefile.am. Original patch by cras.
777 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
779 * Pid file configuration, and server's config file fixes
780 patch by toma. Updated CREDITS file.
782 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
784 * Fixed silc_client_channel_message to not try to decrypt
785 the message twice if it resolved the destination client
786 information. This could cause of dropping one channel
787 message. Affected file lib/silcclient/client_channel.c.
789 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
791 * Added silc_client_run_one into lib/silcclient/silcapi.h and
792 lib/silcclient/client.c. This function is used when the SILC
793 Client is run under some other scheduler, or event loop or
794 main loop. On GUI applications, for example this may be
795 desired to used to run the client under the GUI application's
796 main loop. Typically the GUI application would register an
797 idle task that calls this function multiple times in a second
798 to quickly process the SILC specific data.
800 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
802 * Fixed silc_server_drop() for dropping the supplementary
803 groups as well, this could cause a security hole on some
806 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
808 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
811 * Write PID file after dropping privileges. Added -F option
812 to run server on foreground. A patch by debolaz.
813 Affected files silcd/server.c, silcd/silcd.c.
815 * Fixed MOTD to return the MOTD file server name. Affected
816 file silcd/command.c.
818 * Added INFO command reply handling to the Irssi SILC Client.
819 Affected file irssi/src/silc/core/client_ops.c.
821 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
823 * Fixed the silc_idcache_list_* routines to really support
824 the dynamic list. Fixes a crash. Affected file is
825 lib/silccore/silcidcache.c.
827 * Fixed the LIST command reply to really call LIST command's
828 pending callbacks. Affected file silcd/command_reply.c.
830 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
832 * Update conn->local_entry->nickname after giving NICK
833 command. Affected file lib/silcclient/command.c.
835 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
837 * Added the [pid] option to the silcd configuration file
839 Affected files: serverconfig.[ch] and silcd.c
841 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
843 * Save fingerprint in WHOIS command reply in server.
844 Affected file silcd/command_reply.c.
846 * Fixed NICK commands pending callback registration.
847 Affected file lib/silcclient/command.c.
849 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
851 * Use ++server->cmd_ident when sending commands in server,
852 instead of random number. Affected file silcd/command.c.
854 * Fixed GETKEY command reply to call actually GETKEY pending
855 command callbacks. Affected file silcd/command_reply.c.
857 * A bit stricter check for nicknames. Check for same nickname
858 in NICK command also. Affected file silcd/command.c.
860 * Do not call INFO command everytime client ID changes, only
861 during first connecting. Affected file lib/silcclient/client.c.
863 * Set the new nickname only after successful command reply for
864 NICK command is returned by server. Affected file
865 lib/silcclient/command.c.
867 * Remove nicknames from nicklist during server_signoff notify.
868 Should fix /NAMES bit more. The affected file is
869 irssi/src/silc/core/silc-channels.c.
871 * Added `fingerprint' field to the SilcIDListData in the
872 silcd/idlist.h to hold the fingerprint of the client's
875 Send the fingerprint of the client's public key in WHOIS
878 Affected files silcd/command.c, and silcd/idlist.[ch].
880 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
881 create fingerprint from given data.
883 * Show the fingerprint of the client's public key in WHOIS.
884 Affected files irssi/src/module-formats.[ch] and
885 irssi/src/silc/core/client_ops.c.
887 * Format the multiple same nicknames also during JOIN and
888 NICK_CHANGE notifys. Affected file is
889 lib/silcclient/client_notify.c.
891 * Do not print error on screen for invalid private message
892 payload since it can come if someone is sending private
893 messages with wrong key. Affected file
894 lib/silccore/silcprivate.c.
896 * Fixed multiple concurrent /PING crash. Affected file
897 lib/silcclient/command.c.
899 * Changed the wrong ID encoding. All IP addresses must be
900 in MSB first order in encoded format. They were encoded
901 wrong and was in LSB format. Affected files are
902 silcd/serverid.c, lib/silcutil/silcutil.c.
904 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
906 * Call the `connect' client operation through the scheduler
907 in case of error. Affected file lib/silcclient/client.c.
909 * Call the `failure' client operation even if the error
910 occurred locally during a protocol. Affected file is
911 lib/silcclient/protocol.c.
913 * Added support of sending LIST command to router from normal
914 server. This way normal server can get list of all channels
915 in the network too. Fixed the channel list sending in the
916 server too. Affected files are silcd/command.c, and
917 silcd/command_reply.[ch].
919 * Added silc_server_update_channels_by_server and
920 silc_server_remove_channels_by_server. They are used during
921 disconnection of primary router and in backup router protocol.
922 Affected file silcd/server_util.[ch], silcd/server.c and
923 silcd/server_backup.c.
925 * Fixed channel adding to global list in IDENTIFY command
926 reply in server. Affected file silcd/command_reply.c.
928 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
930 * If the incoming packet type is REKEY or REKEY_DONE process
931 that packet always synchronously. Fixes yet another MAC
932 failed error on slow (dialup) connections. Affected file
933 lib/silcclient/client.c and silcd/server.c.
935 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
937 * Call check_version SKE callback for initiator too. Affected
938 file lib/silcske/silcske.c.
940 * Implemented fix for security hole found in the SKE that was
941 fixed in the specification few days back; the initiator's
942 public key is now added to the HASH value computation.
943 Added backwards support for the old way of doing it too, for
944 old clients and old servers. Affected file is
945 lib/silcske/silcske.c.
947 * Enabled mutual authentication by default in SKE. If initiator
948 is not providing mutual authentication the responder will
949 force it. This will provide the proof of posession of the
950 private key for responder. The affected files are
951 lib/silcclient/protocol.c and silcd/protocol.c.
953 * Do not cache anymore the server's public key during SKE.
954 We do mutual authentication so the proof of posession of
955 private key is done, and if the server is authenticated in
956 conn auth protocol with public key we must have the public
957 key already. Affected file silcd/protocol.c.
959 * Added new global debug variable: silc_debug_hexdump. If
960 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
961 file lib/silcutil/silclog.[ch].
963 * Fixed compilation warning due to char * -> const char *.
964 Affected files lib/silcutil/silcnet.h, and
965 lib/silccore/silcauth.[ch].
967 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
969 * Fixed CMODE command when new channel key was created. If
970 the creation failed the old key was removed. Next time giving
971 same command would crash the server since the old key was
972 freed already. Affected file silcd/command.c.
974 * Fixed the silc_server_announce_get_channels to not crash
975 on reconnect. Affected file silcd/server.c.
977 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
979 * Added silc_log_set_debug_string function to set a regex
980 string to match for debug output. Only the function names,
981 or filenames matching the given debug string is actually
982 printed. This way it is possible to filter out those debug
983 strings that user is not interested in.
985 Fixed a bug in silc_string_regexify.
987 Affected files lib/silcutil/silclog.[ch], and
988 lib/silcutil/unix/silcunixutil.c.
990 * Changed the -d options in both server and Irssi SILC client
991 to take the debug string as argument. Affected files
992 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
994 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
996 * Added silc_hash_babbleprint to create a Bubble Babble
997 Encoded fingerprint. The encoding is developed by Antti
998 Huima (draft-huima-babble-01.txt), and it creates human
999 readable strings out of binary data. Affected file
1000 lib/silccrypt/silchash.[ch].
1002 * Print the babble print now in addition of fingerprint as well
1003 in Irssi SILC client. Affected files are
1004 irssi/src/fe-common/silc/module-formats.[ch],
1005 irssi/src/fe-common/silc/core/client_ops.c.
1007 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1009 * Fixed a security problem found in SKE. The initiator's
1010 public key too is now added to the HASH hash value creation
1011 which is signed by the responder to create the SIGN value.
1012 This will prevent anyone in the middle to lie to the responder
1013 about the initiator's public key. If this is done now, the
1014 man in the middle will get caught. Updated the protocol
1017 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1019 * Better installation directory handling. Configure module
1020 paths and other paths automatically to example_silc* files
1021 in doc/. A patch by toma.
1023 * Fixed compiler warning from MPI library, and from SILC RNG.
1026 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1027 It can be configured with ./configure. A patch by toma.
1029 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1031 * Find correct make to use in prepare-clean. A patch by
1032 toma. Affected file prepare-clean.
1034 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1036 * Added irssi variables use_auto_addr, auto_bind_ip,
1037 auto_bind_port and auto_public_ip.
1039 * Changed the interface for silc_client_send_key_agreement
1040 in lib/silcclient/silcapi.h
1044 irssi/src/silc/core/silc-core.c
1046 lib/silcclient/silcapi.h
1047 irssi/src/silc/core/silc-channels.c
1048 lib/silcclient/client_keyagr.c
1051 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1053 * Added silc_pkcs_public_key_compare to compare two
1054 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1056 * Check that the client who set the founder mode on the
1057 channel is the same client that is giving the founder
1058 mode to itself. It is done by comparing the saved public
1059 key (it is saved even in the authentication is passphrase).
1060 Affected file silcd/command.c.
1062 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1064 * Do not process packet for disconnected socket connection.
1065 Affected file lib/silccore/silcpacket.c.
1067 * Process the DISCONNECT packet through scheduler in the
1068 client library. Affected file lib/silcclient/client.c.
1070 * Fixed the silc_client_packet_parse to not to increase
1071 the packet sequence number if the conn->sock and the
1072 current socket connection is not same. This can happen
1073 for example during key agreement when the conn includes
1074 multiple socket connections (listeners). Affected file
1075 lib/silcclient/client.c.
1077 * The sender of the file transfer request now provides also
1078 the pointer (listener) for the key exchange protocol. If
1079 the listener cannot be created then it sends empty key
1080 agreement and lets the receiver provide the listener.
1082 Added `local_ip' and `local_port' arguments to the
1083 silc_client_file_send. If they are provided they are used,
1084 if not then it will attempt to find local IP address, if
1085 not found or bind fails then the remote client will provide
1088 Affected files are lib/silcclient/client_ftp.c and
1089 lib/silcclient/silcapi.h.
1091 * Extended the FILE SEND command to support defining the
1092 local IP and port for key exchange listener. They are
1093 optional. Affected file irssi/src/silc/core/silc-servers.c.
1095 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1097 * Defined to WHOIS command reply the sending of fingerprint
1098 of the client's public key (if the proof of posession of the
1099 corresponding private key is verified by the server).
1100 Updated to the protocol specification.
1102 * Added support of receiving the client's public key's
1103 fingerprint in command reply in client library. Affected
1104 file is lib/silcclient/command_reply.c, and
1105 lib/silcclient/idlist.[ch].
1107 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1109 * Do not send over 128 chars long nickname to the server
1110 in NICK command. Affected file lib/silcclient/command.c.
1112 * Do not send over 256 chars long channel names to the server
1113 in JOIN command. Affected file lib/silcclient/command.c.
1115 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1164 preserve the WHOWAS info for the client. Affected file
1165 silcd/server_util.c.
1167 * Fixed SERVER_SIGNOFF notify handling in the server. The
1168 server is now able to process incoming SERVER_SIGNOFF notify
1169 for a server that it doesn't even know about. It will remove
1170 the clients provided in the notify. Affected file
1171 silcd/packet_receive.c.
1173 * Check for partial packet in data queue after every packet that
1174 was found from the queue. Return and wait for more data if
1175 there is partial data in queue. Affected file is
1176 lib/silccore/silcpacket.c.
1178 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1193 irssi/src/fe-common/silc/module-formats.[ch].
1195 * Wrote a help file for FILE command.
1197 * Added silc_rng_global_get_byte_fast to get not-so-secure
1198 random data as fast as possible. Random data is read from
1199 /dev/urandom if available and from the SILC RNG if not
1200 available. It is used in padding generation. Affected file
1201 lib/silccrypt/silcrng.[ch].
1203 * All packets in client library are now processed synchronously.
1204 Optimized packet processing a lot. Affected file
1205 lib/silcclient/client.c.

1216 * Assure that silc_client_notify_by_server_resolve does not
1217 resolve the client information multiple times. If it cannot
1218 be found by the first it cannot be found at all. Affected
1219 file lib/silcclient/client_notify.c.
1221 * Fixed WHOWAS command reply calling. Affected file
1222 lib/silcclient/command_reply.c.
1224 * Removed all references to silc_idlist_get_client from the
1225 Irssi SILC client since that call is internal call used by
1226 the library. The Irssi SILC client will use now client
1227 retrieval functions found in silcapi.h.
1229 * Fixed a bug in resolving nickname info before sending
1230 private message. It used freed memory. Affected file
1231 irssi/src/silc/core/silc-servers.c.
1233 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1235 * Assure my_channels statistics cannot go negative in server.
1236 Affected files silcd/server.c, silcd/server_util.c.

1252 * Added silc_net_localip to return local host's IP address.
1253 Affected file lib/silcutil/silcnet.[ch].
1255 * If key exchange or rekey protocol is active for a connection
1256 parse all packets syncronously since there might be packets
1257 in packet queue that we are not able to process without first
1258 processing packets before them. Affected file silcd/server,
1259 lib/silcclient/client.c.
1261 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1262 whether library should continue processing the packet.
1263 Affected file lib/silccore/silcpacket.h.

1309 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1310 is incomplete and is being resolved, it won't be resolved
1313 Make sure also that USERS command reply does not resolve
1314 twice information. Affected file is
1315 lib/silcclient/command_reply.c.
1317 Make sure that silc_client_get_clients_by_list does not
1318 resolve twice same information.
1320 * Check for valid client->id in the silc_server_free_client_data.
1321 Affected file silcd/server.c.
1323 * Fixed /GETKEY nick@server not to crash if the server entry
1324 is not found. Affected file lib/silcclient/command.c.
1326 * Fixed the silc_server_check_cmode_rights to check the
1327 requested modes correctly. Affected file silcd/command.c.

1332 Affected file silcd/command.c.
1334 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1336 * Call the silc_server_udpate_servers_by_server in the
1337 primary router that comes back online in the backup resuming
1338 protocol. Otherwise it routes packets wrong. Affected file
1339 silcd/server_util.[ch], silcd/server_backup.c.
1341 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1343 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1344 lib/silcutil/silcbuffmt.[ch].
1346 * Redefined the SILC packet header to include the padding
1347 length. Affected file lib/silccore/silcpacket.[ch].
1349 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1350 length for maximum padding up to 128 bytes). Affected
1351 file lib/silccore/silcpacket.h.
1353 * Removed all backwards support for old 0.5.x MAC thingies.
1354 The SILC packet header change makes it impossible to be
1355 backwards compatible.
1357 * Send the ENDING packet with timeout in the backup resuming
1358 protocol. This is to assure that all routers has connected
1359 to the primary router. Affected file silcd/server_backup.c.
1361 * Changed the RNG to take the first IV from random data. It
1362 used to take it from zero actually. Changed the RNG also
1363 to use /dev/urandom during session. /dev/random is used
1364 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1366 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1368 * Changed the SILC packet header to have the first two bytes
1369 (the packet length) encrypted. Affected files aroung the
1370 code tree, lib/silccore/silcpacket.[ch]. Removed the
1371 SilcPacketCheckDecrypt callback. It is not needed anymore
1372 since the silc_packet_receive_process will determine now
1373 whether the packet is normal or special.
1375 * Implemented the unidirectional MAC keys. Affected files
1376 lib/silcske/silcske.c, silcd/protocol.c and
1377 lib/silcclient/protocol.c.
1379 * Implemented the packet sequence number to the MAC computation.
1380 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1381 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1382 lib/silcclient/protocol.c.
1384 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1386 * Allow backup router to announce servers. All servers
1387 announced by backup router are added to the global list
1388 automatically. Update hte server's socket to our primary
1389 router also when backup router announces a server.
1390 Affected file silcd/packet_receive.c.
1392 * Do not update the client->router in the function
1393 silc_server_udpate_clients_by_server if the client is on
1394 global list. We might fail to find any specific server
1395 for locally connected clients and local cell clients. They
1396 should still use the `from' and not `to' as client->router.
1397 This fixes backup router resuming protocol. Affected file
1398 silcd/server_util.c.
1400 * Decrease channel statistics count only if the channel
1401 deletion worked. Affected files are silcd/server.c and
1402 silcd/server_util.c.
1404 * Added silc_server_update_servers_by_server to update origin
1405 of all server entries. Used during backup router protocol.
1406 Affected files silcd/server_util.[ch], silcd/server.c. and
1407 silcd/backup_router.c.
1409 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1410 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1411 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1412 lib/silccrypt/silchmac.c.
1414 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1416 * Assure that router cannot reroute the same channel message
1417 to the sender. Affected file silcd/packet_receive.c.
1419 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1421 * Made better checks that the channel message is not sent
1422 to the router it came from. Affected file is
1423 silcd/packet_send.c. Fixed memory leak too.
1425 * Announce informations for incoming router connection, but
1426 only after checking if it is replaced by backup router.
1427 Affected file silcd/packet_receive.c.
1429 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1431 * Fixed the backup resuming protocol to work in multiple
1432 router environment. Affected file silcd/server_backup.c.
1434 * Route packet only to one router in the function
1435 silc_server_packet_send_to_channel. Affected file is
1436 silcd/packet_send.c.
1438 * Fixed silc_server_send_notify_dest to set the broadcast
1439 flag. Fixed the silc_server_send_notify_topic to actually
1440 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1441 Affected file silcd/packet_send.c.
1443 * Changed the SFTP Filesystem interface. Changed the
1444 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1445 the filesystem operation function. The SilcSFTPFilesystem
1446 is now a context that is allocated by all filesystem allocation
1447 functions and it already includes the operations structure
1448 and filesystem specific context. It is given as argument
1449 now to the silc_sftp_server_start. This made the interface
1450 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1451 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1453 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1455 * Changed the backup router adding and getting interfaces
1456 in the server. The router that will be replaced by the
1457 specified backup router is now sent as argument. Affected
1458 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1461 * Added silc_net_addr2bin_ne to return the binary form of
1462 the IP address in network byte order. Affected files
1463 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1465 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1467 * Check for existing server ID in silc_server_new_server
1468 and in silc_server_connect_to_router_final and remove the
1469 old entry if it exists. Affected file silcd/packet_receive.c,
1472 * Send the channel message always to only one router, either
1473 in upstream or downstream. Affected file is
1474 silcd/packet_send.c.
1476 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1478 * Wrote the definition of the backup resuming protocol to the
1479 protocol specification.
1481 * Removed one redundant channel key generation from normal
1482 server during joining procedure. Removed one redundant
1483 channel key sending from server to router during joining
1484 procedure. Affected file silcd/command.c.
1486 * Made minor bugfixes to the backup router resuming protocol.
1487 Affected file silcd/server_backup.c, server.c.
1489 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1491 * Added --disable-asm configuration option. Affected files
1492 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1495 * Implemented the backup resuming protocol that is used to
1496 resume the primary router position in the cell after the
1497 primary router comes back online. Affected files
1498 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1499 and silcd/server_util.[ch].
1501 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1503 * Sleep two (2) seconds after sending QUIT command to server.
1504 Affected file lib/silcclient/command.c.
1506 * Assure that if outgoing data buffer is pending do not force
1507 send any data. Affected file silcd/packet_send.c.
1509 * Assure that if outgoing data buffer is pending do not force
1510 send any data. Affected file lib/silcclient/client.c.
1512 * Implemented the backup router support when the primary router
1513 goes down. The servers and routers can now use the backup
1514 router as new primary router without loosing connectivity.
1516 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1518 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1519 in the server to indicate disabled entry. All data read
1520 from the connection will be ignored and no data is sent
1521 for entry that is disabled. Affected files are
1522 silcd/idlist.h, silcd/server.c.
1524 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1526 * Created SFTP client and server test programs in the
1527 lib/silcsftp/tests directory.
1529 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1531 * Implemented memory filesystem (virtual filesystem) for
1532 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1535 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1537 * Implemented the SFTP (SSH File Transfer Protocol) to the
1538 lib/silcsftp. It includes SFTP client and SFTP server
1541 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1543 * Moved lib/silccore/silcprotocol.[ch] to the
1544 lib/silcutil library.
1546 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1547 take variable argument list pointer as argument. Affected
1548 file lib/silcutil/silcbuffmt.[ch].
1550 * Added silc_buffer_set function that is used to set data
1551 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1552 Affected file lib/silcutil/silcbuffer.h.
1554 * Changed various routines in the core library to use the new
1555 silc_buffer_set instead of allocating new buffer only for
1558 * Added 64-bit value formatting and unformatting support to the
1559 silc_buffer_[un]format routines. Affected file is
1560 lib/silcutil/silcbuffmt.[ch].
1562 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1563 to includes/bitmove.h.
1565 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Fixed channel user mode saving in client library. Affected
1568 file lib/silcclient/command[_reply].c.
1570 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Defined the file transfer to the SILC Protocol. Added
1573 new packet type SILC_PACKET_FTP and defined File Transfer
1574 Payload. The mandatory file transfer protocol is SFTP
1575 (SSH File Transfer Protocol). Affected file in addition
1576 of the internet draft is lib/silccore/silcpacket.h.
1578 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1579 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1580 is used as part of backup router protocol when the primary
1581 router of the cell is back online and wishes to resume
1582 the position as primary router.
1584 * Redefined the MAC generation keys in the protocol. The
1585 same key is not used anymore in both direction. Both
1586 direction will now use different keys for sending and
1587 receiving. This fixes a potential security flaw. This
1588 change causes incompatibilities in the protocol.
1590 * Redefined also the MAC computation from the packet.
1591 An packet sequence number is now added to the MAC
1592 computation. This prevents possible replay attacks against
1593 the protocol. This change too causes incompatibilities
1596 Added `sequence' field to the SilcPacketContext to hold
1597 the current sequence number for the packet.
1599 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1601 * Added `created' field to the SilcIDListData in the file
1602 silcd/idlist.h to indicate the time when the entry was
1605 * Added `created' field to the SilcChannelEntry too. Affected
1606 file silcd/idlist.h.
1608 * Added `creation_time' aguments to all the announcement functions
1609 in the server. If it is provided then only the entries that
1610 was created after the provided time frame are actually
1611 announced. Affected file silcd/server.[ch].
1613 * The protocol says that the Channel ID's IP address must be
1614 based on the router's IP address. Added check for this in
1615 the silc_server_new_channel when processing incoming New Channel
1616 Payload. Affected file silcd/packet_receive.c.
1618 * Print out the correct version with --version in SILC client.
1619 Affected file irssi/src/silc/core/silc-core.c.
1621 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1623 * Fixed WHOWAS command to check for completnes of the client
1624 entry always, not just when the command is coming from client.
1625 Affected file silcd/command.c.
1627 * Added new function silc_server_packet_queue_purge to purge the
1628 outgoing data queue to the network. After the function returns
1629 it is guaranteed that the outgoing packet queue is empty.
1630 Affected file silcd/packet_send.[ch].
1632 * Purge the outgoing packet queue in the rekey protocol's final
1633 callback to assure that all rekey packets go to the network
1634 before quitting the protocol. Affected file silcd/server.c.
1636 * Added silc_client_packet_queue_parse as similar function as
1637 in server to the client library. The affected file is
1638 lib/silcclient/client.c.
1640 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1642 * Splitted silcd/server.c and created silcd/server_util.[ch]
1643 for utility functions.
1645 * Added new socket flag SILC_SF_DISABLED to indicate that the
1646 connection is open but nothing can be sent to or received from
1647 the connection. Affected file lib/silcutil/silsockconn.[ch].
1648 The checking for disabled socket is checked in the low level
1649 silc_socket_write and silc_socket_read functions.
1651 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1653 * Allow only nicknames and channel names that fits into the
1654 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1656 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1658 * When processing JOIN command reply in server check that if
1659 the channel exists in our global list we'll move it the local
1660 list. Affected file silcd/command_reply.c.
1662 * Fixed the check whether client is joined on the channel already
1663 in JOIN command. Affected file lib/silcclient/command.c.
1665 * Fixed the JOIN command reply to check whether the channel
1666 already exists. Affected file lib/silcclient/command_reply.c.
1668 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1670 * Added silc_ske_status_string to map the SKE error numbers
1671 to readable strings. The affected files are
1672 lib/silcske/silcske[_status].[ch].
1674 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1676 * Do not show the private channels on the WHOIS channel list
1677 as it is not allowed by the protocol. The affected file is
1680 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1682 * Assure that the packet length digged from the actual packet
1683 is something sensible in the silc_packet_decrypt_rest_special
1684 in lib/silccrypt/silcpacket.c.
1686 * Free and NULL the allocated pointer in silc_hmac_alloc if
1687 the HMAC allocation fails. The affected file is
1688 lib/silccrypt/silchmac.c.
1690 * Print the selected security properties to the log files in
1691 the server. Affected file silcd/protocol.c.
1693 * Add SKE's reference counter even if calling the completion
1694 callback manually. Otherwise it goes negative, although it
1695 does not cause any problems. The affected file is
1696 lib/silcske/silcske.c.
1698 * Remove the client entry with short timeout after giving the
1699 KILL command. Affected file lib/silcclient/command.c.
1701 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1702 case all found clients are already disconnected (WHOWAS would
1703 found them) in the server. Affected file silcd/command.c.
1705 * Update the last_receive (time of last data received) to be
1706 updated only when received private or channel message so that
1707 the idle time showed in WHOIS makes more sense.
1709 * Added boolean field `valid' in to the SilcClientEntry in the
1710 client library to indicate whether the entry is valid or not.
1711 This fixes the nickname change bug on channel when changing
1712 the nickname to be same than the old (like nick to Nick) the
1713 nickname formatter doesn't set the new nick anymore to Nick@host.
1714 Affected file lib/silcclient/idlist.[ch].
1716 * Now actually fixed the nickname changing on disconnection.
1717 Added new function silc_change_nick to the Irssi SILC Client.
1718 Affected file irssi/src/silc/core/client_ops.c,
1719 irssi/src/silc/core/silc-nicklist.[ch].
1721 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1723 * Check that the public key exists in the GETKEY command before
1724 trying to encode it. Affected file silcd/command.c.
1726 * Print some notifications on received public keys with GETKEY
1727 command in the Irssi SILC Client. Affected files are
1728 irssi/src/fe-common/silc/module-formats.[ch],
1729 irssi/src/silc/core/client_ops.c.
1731 * Use IDENTIFY command to resolve the server information in the
1732 GETKEY command instead of INFO command. Affected file
1733 lib/silcclient/command.c.
1735 * All command reply functions in the client library now calls
1736 the pending command reply callbacks even if an error has
1737 occurred. The server has done this a long time and now it was
1738 time to move the client library to this as well. Now all
1739 errors can be delivered back to the pending command reply
1740 callbacks if necessary. Affected files are
1741 lib/silcclient/command[_reply].[ch].
1743 * Change the nickname on disconnection back to the username
1744 because in reconnect the server will enforce it to it anyway.
1745 Affected file irssi/src/silc/core/silc-servers.c.
1747 * Fixed a config file parsing bug in the Irssi SILC client.
1748 Affected file irssi/src/silc/core/clientconfig.c.
1750 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1752 * When printing the channel mode on JOIN, verify that the
1753 channel key and channel's HMAC are valid. Affected file
1754 irssi/src/silc/core/client_ops.c.
1756 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1758 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1759 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1760 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1762 * Removed channel key rekey task deleting from the function
1763 silc_server_save_channel_key. Affected file silcd/server.c.
1764 Added explicit timeout task context instead that is used to
1765 delete the task if we are registering a new task before the
1766 new task has elapsed.
1768 * When channel key rekey occurs the client library now saves
1769 the old channel key for a short period of time (10 seconds) and
1770 is able to use it in case some is still sending channel
1771 messages encrypted with the old key after the rekey. Affected
1772 file lib/silcclient/[idlist.h|client_channel.c].
1774 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1776 * Added check to the silc_server_new_id_real to not accept
1777 new ID if it is the sender's own ID. Affected file is
1778 silcd/packet_receive.c.
1780 * Assure that we do not announce ourself or the one we've
1781 sending our announcements when we're router and are announcing
1782 servers to our primary router. Affected file silcd/server.c.
1784 * Fixed silc_server_command_identify_check_client to assemble
1785 correct WHOIS packet. It send corrupted WHOIS packet and
1786 caused problem with router to router connections. Affected
1787 file silcd/command.c.
1789 Fixed also silc_server_command_whois_check the same way
1790 as for the IDENTIFY command.
1792 * Added new SilcIDListStatus to the server in the SilcIDListData
1793 structure. The status now includes the current status of
1794 the entry (like registered, resolved etc.). Affected file
1795 silcd/idlist.[ch]. Defined a bunch of different status types
1796 as well. This replaced the old boolean registered field as well.
1798 Added resolve_cmd_ident field to the SilcClientEntry structure
1799 too so that if the entry is for example being resolved so
1800 another command may attach to the same pending command reply
1801 without requiring to resolve the same entry again. This concept
1802 should optimize the WHOIS and the IDENTIFY resolving under
1803 heavy load by taking away unnecessary resolving for entries
1804 that are being resolved already.
1806 Added support for adding multiple pending commands for one
1807 command idenfier. Affected file silcd/command[_reply].[ch].
1809 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1810 before deleting the data. Otherwise the hash table will have
1811 freed data in comparison functions. Affected file is
1812 silcd/command_reply.c.
1814 * Fixed silc_idlist_replace_client_id to add the new entry to
1815 the cache with NULL nickname. Otherwise there will be invalid
1816 memory as the nickname after the nickname is freed. Affected
1817 file silcd/packet_receive.c.
1819 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1820 saved into wrong slots because the previous number of entries
1821 was not taken into account. Affected file silcd/idlist.c.
1822 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1824 * If we are router and we receive JOIN notify to a channel that
1825 does not have any users then notified client is marked as the
1826 channel founder, as it is it. The affected file is
1827 silcd/packet_receive.c
1829 * Added to the extended hash table API's table_del_*ext functions
1830 the destructor as argument too, so that the caller can decide
1831 which destructor to use or whether to use destructor at all.
1832 Affected file lib/silcutil/silchashtable.[ch].
1834 * Fixed ID Cache purging. It actually deleted the entries from
1835 the hash table after the data was freed. The hash table ended
1836 up comparing freed memory. The affected file is
1837 lib/silccore/silcidcache.c.
1839 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1841 * Fixed Irssi SILC client's KILL command's HELP syntax.
1843 * The USERS command now resolves the detailed user information
1844 if the userinfo field is missing. Affected file is
1845 lib/silcclient/command_reply.c.
1847 * Do not print error in silc_file_read if the read file does
1848 not exist. Just silently return NULL. Affected file is
1849 lib/silcutil/silcutil.c.
1851 * Fixed the silc_log_output to not wine about NULL filename
1852 and to not create some bogus " " filename. Affected file is
1853 lib/silcutil/silclog.c.
1855 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1857 * Fixed various printing bugs on the user interface in the
1858 Irssi SILC Client. Minor changes that were forgotten from
1861 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1863 * Fixed the configure.in.pre and the compilation and distribution
1864 environment to support the new autoconf 2.52. That version is
1865 now required to compile the CVS trunk.
1867 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1869 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1870 to generally parse user@fqdn format strings. Affected file
1871 lib/silcutil/silcutil.c.
1873 * Added nickname_format and nickname_force_format fields to the
1874 SilcClientParams structure. The first one defines the format
1875 for the nicknames that the library will enforce if the receives
1876 multiple same nicknames. The second one is boolean value and
1877 can be used to force the library to always enforce the format
1878 to the nicknames regardles whether there are multiple nicknames
1879 or not. This configurable formatting was employed to flexibly
1880 support accessing multiple nicknames from the user interface.
1881 The userinterface can now set the nicknames to what ever format
1882 they prefer. Affected file lib/silcclient/silcapi.h.
1884 Added function silc_client_nickname_format to the file
1885 lib/silcclient/idlist.c. It performs the nickname formatting.
1887 Added new field `hostname´ to the SilcClientEntry context.
1888 It holds the hostname of the client. Affected file is
1889 lib/silcclient/idlist.h.
1891 * Irssi SILC Client sets the nicknames in nick@hostn format.
1892 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1893 irssi/src/silc/core/silc-core.c.
1895 The WHOIS printing now also shows both the real nickname and
1896 the formatted nickname so that user knows how to access the
1897 user if there are multiple same nicknames cached. Affected
1898 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1899 printing formatting too to take the hostname now as a separate
1900 argument. The Affected file is
1901 irssi/src/fe-common/silc/modules-formats.[ch].
1903 * Changed the silc_client_get_clients_local to accept the formatted
1904 nickname as argument. It accepts the real nickname too but the
1905 formatted nickname can be used to find the true entry from
1906 multiple entries. Affected file lib/silcclient/silcapi.h and
1907 lib/silcclient/idlist.c.
1909 * Added nickname_format_parse field to the SilcClientParams.
1910 It is a callback function provided by the application to parse
1911 the nickname out of the formatted nickname string. The library
1912 calls it to get the nickname from the formatted string. Since
1913 the application generally knows better the format of the nickname
1914 string it parses it instead of the library, even though library
1915 encodes the formatted string. If the callback function is not
1916 provided then the library will use the string as is. The
1917 affected file is lib/silcclient/silcapi.h.
1919 * All the nickname strings passed to the client library in
1920 commands are now expected to be formatted nickname strings.
1921 If the command does not support the formatted nickname string
1922 it will assume that the sent string is the actual nickname.
1923 Affected file lib/silcclient/command.c.
1925 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1927 * Added public key authentication support to OPER and SILCOPER
1928 commands in the client library. Affected file is
1929 lib/silcclient/command.c.
1931 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1933 * Changed the get_auth_methdod client operation to be asynchronous.
1934 It can be async if the application resolves the authentication
1935 method from the server during the negotiation. Added new
1936 SilcGetAuthMeth completion callback that the application will
1937 call after resolving the authentication method.
1939 Added function silc_client_request_authentication_method that
1940 the application can use to resolve the authentication method
1941 from the server. Added also SilcConnectionAuthRequest callback
1942 that the library will call after the server has replied. The
1943 application can call this function if it does not know the
1944 current authentication method.
1946 Affected files are lib/silcclient/client.c and
1947 lib/silcclient/silcapi.h.
1949 * The Irssi SILC client now automatically resolves the authentication
1950 method incase any configuration information is not present (and
1951 currently there never is). The affected file is
1952 irssi/src/silc/core/client_ops.c.
1954 * Fixed public key authentication from the client library.
1955 Affected file lib/silcclient/protocol.c. Changed also the
1956 protocol specification about the public key authentication in
1957 the connection authentication protocol. The actual data to be
1958 signed is now computed with a hash function before signing.
1960 * Fixed the public key authentication from the server as well.
1961 Affected file silcd/protocol.c.
1963 * Removed the mlock()'s from the memory allocation routines.
1964 Affected file lib/silcutil/silcmemory.c. The ./configure does
1965 not check anymore for the mlock(). Affected file is
1968 * Fixed USERS command in server to allow the execution of the
1969 command for private and secret channels if the client sending
1970 the command is on the channel. Affected file silcd/command.c.
1972 * Fixed silc_client_get_clients_local to return the clients
1973 count correctly. It could return wrong value. Affected file
1974 lib/silcclient/idlist.c.
1976 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1978 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1979 types. The assembler optimizations seemed not to like 64-bit
1980 data types. The assmebler optimizations thus are now enabled
1981 also for BSD systems as opposed to only enable them for Linux.
1983 * Do not check for threads at all on BSD systems. Affected
1984 file configure.in.pre.
1986 * Removed -n and -h options from the Irssi SILC Client since
1987 they are not used in silc.
1989 * Fixed the prime generation to assure that the first digit
1990 of the generated random number is not zero since our conversion
1991 routines does not like number strings that starts with zero
1992 digit. If zero digit is seen the random number is regenerated.
1993 This caused some corrupted RSA keys when the zero first digit
1994 was met. Affected file lib/silcmath/silcprimegen.c.
1996 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1998 * Fixed WIN32 configuration in the ./configure script.
1999 Fixed to include xti.h on environments that has it.
2000 Patches by Carsten Ilchmann and andrew.
2002 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2004 * Changed the silc_id_create_client_id to be collision
2005 resistant. It is now assured that there cannot be created
2006 two same client ID's. I suspect that some weird bugs in
2007 the server were actually caused by duplicate Client IDs.
2008 Affected file silcd/serverid.[ch]. A router receiving
2009 new ID now also assures and informs the sending server
2010 if the ID caused collision.
2012 * Changed the silc_id_create_channel_id to also assure that
2013 there are no collisions.
2015 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2017 * Statement about ignoring the Mutual Authentication flag when
2018 performing rekey with PFS was a bit misleading. It is ignored
2019 if it was set in the initial negotiation, it cannot be even
2020 set in the rekey. Fixed in the ke-auth draft. Started the
2021 new versions of the protocol drafts in the doc/.
2023 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2025 * Fixed a bug in silc_client_command_identify_save when saving
2026 new channel information. The channel name was no duplicated
2027 and caused crash on exit. Affected file is
2028 lib/silcclient/command_reply.c.
2030 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2032 * Fixed the getkey command handling in the server. Send just
2033 empty OK reply to the sender if the key could not be fetched
2034 (but everything else was ok, like the key just was not available).
2035 Changed the public key parameter to optional in the protocol
2036 specs so that empty OK reply can be sent. Affected file
2039 Added a message to Irssi SILC client to tell to user if the
2040 server did not return a public key.
2042 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2044 * Fixed a channel key regeneration bug. It registered new
2045 timeout tasks exponentially until all system resources were
2046 used. Affected file silcd/server.c.
2048 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2050 * Added the SILC Document generator to the scripts/silcdoc.
2051 It can be used to generate the Toolkit Reference Manual out
2052 of the source tree. Internally it will also use the RoboDoc
2053 generator now imported in util/robodoc.
2055 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2057 * Added couple of return's in rekey protocol if error orccurred
2058 during the protocol. The execution must be terminated.
2059 Affected file silcd/protocol.c. Also, terminate the protocol
2060 always with timeout.
2062 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2064 * The client's Client ID was created initally from the wrong
2065 nickname (it could have been in format nick@host) in the
2066 silc_server_new_client. Affected file silcd/packet_receive.c
2068 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2070 * Added some SILC_LOG_ERROR's to various error conditions
2071 if client could not be added to ID cache. Affected files
2072 silcd/packet_receive.c and silcd/server.c.
2074 * When client's sock->user_data is freed, NULL also the
2075 client->router and client->connection pointers. Added check
2076 for these pointers being NULL to various places around the
2077 code. Affected file silcd/server.c.
2079 * Added client->data.registered == TRUE checks to various
2080 places around the code to assure that unregistered client's
2081 are not handled when it is not allowed. Affected file
2084 * Added `bool registered' fields to all
2085 silc_idlist_[server|client]_get_* routines to indicate whether
2086 the fetched client needs to be registered or not. Affected
2087 file silcd/idlist.[ch].
2089 * Add your own entry as registered to the ID cache in the
2090 server. Affected file server.c.
2092 * Fixed a bug in silc_server_new_server. The SilcServer was
2093 set as the new server's context instead of SilcServerEntry.
2094 This naturally caused some weird bugs.
2096 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2098 * Do not delete the channel rekey task when adding it
2099 for in silc_server_create_channel_key.
2101 * Changed the silc_server_create_channel_key to return
2102 TRUE or FALSE to indicate the success of the channel key
2105 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2107 * Fixed MSVC++ project files and added missing files to
2108 Makefiles under win32/.
2110 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2112 * Do not add TCP_NODELAY flag if the operating system
2113 does not have it defined. Affected files are
2114 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2116 * Fixed buffer overflow from Irssi SILC Client. Affected
2117 file irssi/src/fe-common/core/themes.c.
2119 * Fixed double free in client library in the file
2120 lib/silcclient/client.c when disconnecting from server.
2122 * Applied double free patch from cras to Irssi SILC client.
2123 Affected files irssi/src/core/[modules/expandos].c
2125 * Fixed the disconnection handling to Irssi SILC Client.
2126 The application must call silc_client_close_connection
2127 in ops->connect client operation in case of failure of
2128 the connection. Affected file is
2129 irssi/src/silc/core/client_ops.c.
2131 * Do not set sock->protocol to NULL in the function
2132 silc_client_close_connection after executing the protocol's
2133 final callback since the sock might not be valid anymore.
2134 Affected file lib/silcclient/client.c.
2136 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2138 * Do not enable SILC_THREADS if the linking with libpthread
2139 did not happen. Affected file configure.in.pre.
2141 * Added notion to protocol specification that server must
2142 verify the sent authentication payload with CMODE when
2143 setting the channel founder key. Implemented it to the
2144 server. Affected file silcd/command.c.
2146 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2148 * Added _EXTRA_DIST SILC distribution variable to the
2149 distributions file. It is used to conditionally add extra
2150 files or directories to the specific distribution. Affected
2151 files ./prepare, Makefile.am.pre and distributions.
2153 Removed the `_' from the start of the distribution names.
2156 * Added README.WIN32 for instructions to compile the Toolkit
2159 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2161 * Fixed a double free in disconnection in the server. Affected
2162 file is silcd/server.c.
2164 * Fixed the lib/silcske/groups.c to work now also with GMP
2165 MP library. The string conversion did not work when using
2166 specific base and the base is indicated in the string as well.
2168 * Created win32/ directory which now includes MSVC++ specific
2169 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2170 It will appear only in the toolkit distribution
2172 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2174 * Changed the key material distribution function in case when
2175 the hash output is too short. The data is now concatenated
2176 a bit differently than it used to. Made the change to the
2177 SKE protocol specification.
2179 * Added better GMP detection to configure.in.pre. A patch
2182 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2184 * Fixed a minor bug in SKE that might cause some problem on
2185 some platforms. Affected file lib/silcske/silcske.c.
2187 * Added the cookie checking for initiator in the SKE. It checks
2188 that the responder returns the sent cookie unmodified. The
2189 affected file is lib/silcske/silcske.c. Added new SKE
2190 error type INVALID_COOKIE that can be sent during the
2191 negotiation. Fixed some memory leaks as well.
2193 * Added the "invalid cookie" error message to Irssi SILC client's
2196 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2198 * Added `task_max' field to the SilcClientParams to indicate
2199 the maximum tasks the scheduler can handle. If set to zero,
2200 default values are used. Affected file lib/silcclient/silcapi.h.
2202 * Fixed memory leaks in silc_client_close_connection. Affected
2203 file lib/silcclient/client.c.
2205 * Added silc_client_del_client_entry to client library to free
2206 all memory of given client entry. Affected file is
2207 lib/silcclient/idlist.[ch].
2209 * Added new functions silc_client_del_channel and
2210 silc_client_del_server to delete channel and server entries.
2211 Affected file lib/silcclient/[silcapi.h/idlist.c].
2213 * Removed silc_client_del_client_by_id from silcapi.h.
2215 * Fixed the INFO command to return the server's own info
2216 correctly when querying by Server ID. Affected file is
2219 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2221 * Removed the non-blocking settings in WIN32 code in the
2222 silc_sock_[read/write] and added SleepEx instead. Affected
2223 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2224 of input data is now checked with FIONREAD and ioctlsocket.
2226 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2228 * Call silc_schedule_task_del_by_context in the
2229 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2230 Affected file lib/silccore/silcprotocol.c.
2232 * Call silc_protocol_cancel for active protocols in the
2233 silc_server_close_connection if the funtion
2234 silc_server_free_sock_user_data has not been called.
2235 Affected file silcd/server.c.
2237 * Generic tasks cannot be deleted using the del_by_fd
2238 task deleting function since generic tasks does not match
2239 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2241 * Added a notion to SILCOPER help file that the SILCOPER works
2242 only on router server, not on normal server.
2244 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2246 * Added for WIN32 support for the new scheduler as well.
2247 Affected file lib/silcutil/win32/silcwin32schedule.c.
2249 * Fixed the SHA1 implementation to work on various platforms.
2251 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2253 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2254 API. It is part of the scheduler now. Everything else is
2255 as previously but some functions has changed their names.
2256 Checkout the lib/silcutil/silcschedule.h for the interface.
2257 Updated all applications to use the new interface. Affected
2258 files are lib/silcutil/silcschedule.[ch].
2260 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2262 * Found a bug in the SKE implementation. The HASH value,
2263 specified by the protocol, was not computed correctly. The
2264 public key of the responder was not added to the computation
2265 even though it is mandatory. Affected file lib/silcske/silcske.c.
2266 This unfortunately causes incompatibilities with older
2267 clients and servers.
2269 * Added WIN32 specific network init and uninit functions:
2270 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2271 the Winsock2. Affected file lib/silcutil/silcnet.h and
2272 lib/silcutil/win32/silcwin32net.c.
2274 * Set the socket always to nonblocking mode on WIN32 after
2275 reading data or writing data. Affected file is
2276 lib/silcutil/win32/silcwin32sockconn.c.
2278 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2280 * Fixed various compilation problems under WIN32. Affected
2281 files lib/silcutil/win32/silcwin32thread.c and
2282 lib/silcutil/win32/silcwin32schedule.c.
2284 * Removed all _internal.h #includes from public header
2285 files. Internal headers must never be included from
2288 Removed also the lib/silcske/payload_internal.h file.
2290 * All include files that may be needed (public and some others
2291 included by the public headers) by application developers are
2292 now copied to the ./includes directory. It does not copy any
2293 internal headers. Affected file Makefile.defines.pre and all
2294 Makefile.am's under lib/ and subdirs.
2296 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2298 * Do not change the ~/.silc directory's permissions automatically.
2299 Affected file irssi/src/silc/core/clientutil.c.
2301 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2303 * Do not cancel the protocol in silc_server_close_connection
2304 it might cause recursion. Now cancelled in the function
2305 silc_server_free_sock_user_data. Affected file silcd/server.c.
2307 * Fixed the silc_server_remove_clients_by_server to regenerate
2308 the channel keys correctly finally. Added also new function
2309 silc_server_remove_clients_channels to actually do it.
2310 Affected file silcd/server.c.
2312 * Fixed the silc_server_new_channel to not crash by giving
2313 wrong router to the new channel. Affected file is
2314 silcd/packet_receive.c.
2316 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2318 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2319 which is given as argument to the silc_client_alloc now.
2320 It can be used to configure the client and set various parameters
2321 that affect the function of the client.
2323 * The USERS command in server did not check whether the channel
2324 is private or secret. Affected file silcd/command.c.
2326 * Added new argument to the USERS command in protocol specification.
2327 The USERS command now can take the channel name as argument
2328 as well. Added support for this in client and server and
2329 updated the protocol specs.
2331 * Completed the GETKEY command in client. It can be now used
2332 to fetch also servers public key not only some clients.
2333 Affected files lib/silcclient/command[_reply].c.
2335 * Added silc_client_get_server to return server entry by the
2336 server name. Affected files lib/silcclient/silcapi.h and
2339 * Redefined the IDENTIFY command in protocol specification to be
2340 more generic. It now can be used to query information about
2341 any entity in the SILC Network, including clients, servers and
2342 channels. The query may be based either the entity's name
2343 or the ID. Added support for this in both client and server.
2345 Affected files silcd/command.c and lib/silcclient/command.c
2346 and command_reply.c.
2348 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2349 the _from_client and _from_server functions. Affected file
2352 * Added silc_client_get_channel_by_id_resolve to the file
2353 lib/silcclient/silcapi.h to resolve channel information by
2354 its ID. Added also silc_client_get_channel_by_id that
2355 does not resolve it from the server.
2357 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2359 * Added SilcServerEntry context into the client library
2360 to represent one server. The INFO command now allocates
2361 these to save the resolved server info. For now on the
2362 client library will also keep information about servers,
2363 connected and resolved with INFO.
2365 The INFO command now allocates the SilcServerEntry context
2366 and saves the server info there. The COMMAND_REPLY in
2367 the INFO now returns the parameters to application in
2368 same order as defined in the protocol specification.
2370 The entries are cached in the client->server_cache.
2372 * The INFO command is now issued after received the Client ID
2373 from the server. Affected file lib/silcclient/client.c.
2375 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2376 to the application as the mode changer might be server.
2377 It is guaranteed that NULL is not returned anymore to the
2378 application. Affected file lib/silcclient/client_notify.c.
2380 The ID Type is now also passed to the application so that
2381 it can check whether the returned entry is SilcClientEntry
2384 Added new function silc_client_get_server_by_id to return
2385 the server entry by ID. Affected files are the
2386 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2388 * Do not create the channel in the Irssi SILC Client when issuing
2389 the JOIN command but when received the sucessful JOIN command
2390 reply. Otherwise the channel might get created even though we
2391 could not join it. The Affected file is
2392 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2394 * Fixed a channel joining bug in router. The router must also
2395 check the channel modes, invite and ban lists etc. when serving
2396 the JOIN command sent by normal server. Affected file is
2397 silcd/command.c. The router now resolves the client's
2398 information from the server who sent the JOIN command if it
2399 does not know it, and processes the JOIN command only after
2402 * Changed the SilcCommandCb to take new argument; void *context2.
2403 Affected file lib/silccore/silccommand.h
2405 The second argument in the command callbacks in the server now
2406 includes the SilcServerCommandReplyContext if the command was
2407 called as pending command callback from the command reply.
2408 Otherwise it is NULL. When called as pending the status of the
2409 command reply will be checked and if it was erronous the
2410 error will be sent to the original sender of the command.
2411 This way the client always receives the error messages even
2412 though the server was actually the one who received the error
2413 when it resent the command to router, for example. Affected
2414 files silcd/command[_reply].[ch].
2416 * Fixed sending WHOWAS command's error message to client if
2417 the requested client could not be found. It was missing.
2420 * Changed the CMODE and CUMODE commands reply arguments in the
2421 protocol specification. The Channel ID is now sent in both
2422 of the commands to identify the channel. Implemented this
2423 new feature to the client and server. Affected files
2424 lib/silcclient/command_reply.c and silcd/command.c.
2426 * Made better checks for invite and ban lists in the JOIN
2427 command in server. Affected file silcd/command.c.
2429 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2431 * The server now performs the incoming host IP/DNS lookup
2432 using the silc_socket_host_lookup and thus does not block
2433 the server anymore. Affected file silcd/server.c.
2435 * Completed the multi-thread support for SILC Scheduler in
2436 the lib/silcutil/silcschedule.c.
2438 * Fixed the configure.in.pre to detect the pthread correctly
2441 * Fixed a deadlock in silc_task_queue_wakeup in the file
2442 lib/silcutil/silctask.c.
2444 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2446 * Added new function silc_schedule_wakeup that is used in
2447 multi-threaded environment to wakeup the main thread's
2448 schduler. It needs to be used when a thread adds a new task
2449 or removes a task from task queues. After waking up, the
2450 scheduler will detect the task queue changes. If threads
2451 support is not compiled in this function has no effect.
2452 Implemented the wakeup mechanism to both Unix and WIN32
2453 systems. Affected files are lib/silcutil/silcschedule.[ch],
2454 lib/silcutil/unix/silcunixschedule.c and the
2455 lib/silcutil/win32/silcwin32schedule.c.
2457 * Added new function silc_task_queue_wakeup to wakeup the
2458 scheduler by the specified task queue. Affected file
2459 lib/silcutil/silctask.[ch].
2461 * The silc_socket_host_lookup_start now wakes up the scheduler
2462 after adding the timeout task. Affected file is
2463 lib/silcutil/silcsockconn.c.
2465 * The silc_socket_host_lookup is synchronous now if the threads
2466 support is not compiled in. However, the callback is still
2467 called asyncronously through the scheduler, anyway. Affected
2468 file lib/silcutil/silcsockconn.c.
2470 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2472 * Added new function silc_socket_host_lookup to perform
2473 asynchronous IP and FQDN lookups for the socket connection.
2474 Affected files lib/silcutil/silcsockconn.[ch].
2476 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2478 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2479 that may or may not compile the mutex support in.
2481 Changed the silc_mutex_alloc interface. It allocates the
2482 mutex now to the sent pointer and returns TRUE or FALSE.
2484 Affected file lib/silcutil/silcmutex.h.
2486 * Wrote the SILC Task Queue interface to support multi-threads.
2487 Affected file lib/silcutil/silctask.[ch].
2489 * Wrote the SILC Scheduler to support multi-threads. Affected
2490 file lib/silcutil/silcschedule.c.
2492 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2494 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2495 in lib/silcutil/win32/.
2497 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2499 * Defined SILC Mutex API and SILC Thread API and implemented
2500 them for Unix. Affected files are
2501 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2502 lib/silcutil/unix/silcunixmutex.c and
2503 lib/silcutil/unix/silcunixthread.c.
2505 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2507 * Fixed the silc_server_remove_clients_by_server's channel
2508 key re-generation. The hash table handling was incorrect
2509 and would not work with many channels. Affected file is
2512 * Fixed some memory leaks around the server code.
2514 * Rewrote the silc_server_get_users_on_channel to support IPv6
2515 based Client ID's. Affected file silcd/server.c.
2517 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2518 specification. However, a separate document must be written
2519 to define the detailed signing procedure and the payload
2520 associated with the flag. Defined the flag to the
2521 lib/silccore/silcchannel.h as well.
2523 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2525 * Changed the dynamic tables to static size tables in the
2526 lib/silccrypt/silchmac.c.
2528 * Removed GCC dependencies from the code. A patch by cras.
2530 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2532 * Do not show the error "Error receiving packet bla bla"
2533 in server if it really was not an error (-2 means that reading
2534 is pending). Affected file silcd/server.c.
2536 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2538 * Fixed a possible crash in silc_server_remove_clients_by_server
2539 in silcd/server.c. Fixed there also some memory leaks.
2541 * Fixed the silc_idlist_replace_client_id. It could replace
2542 wrong key in the hash table. Affected file silcd/idlist.c.
2544 * Do not check whether there are global users on the channel
2545 if the channel->global_users is FALSE. Affected functions
2546 silc_server_remove_from_one_channel and
2547 silc_server_remove_from_channels in silcd/server.c. Also,
2548 do not check if the removed client is local as we can be
2549 sure that global client was not removed from the channel
2550 and checking for global users is not needed.
2552 * The silc_server_remove_clients_by_server now re-generates
2553 the channel keys correctly for those channels that had
2554 clients removed from them. Affected file silcd/server.c.
2556 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2558 * Found the reason of random crashes in the server. We weren't
2559 ignoring the SIGPIPE signal (which can be sent in write())
2560 and it crashed the server. Affected file silcd/silcd.c.
2562 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2564 * Assure that sock->user_data is not NULL in the function
2565 silc_server_packet_send in silcd/packet_send.c.
2567 * Disconnect the remote connection if it could not be added
2568 to any ID lists in the server. The affected file is
2571 * Check in silc_server_packet_send[_real/dest] that the
2572 socket is not disconnecting and ignore the data if it is.
2573 Affected file silcd/packet_send.c.
2575 * Define inline to __inline on native WIN32 compilation.
2576 Affected file includes/silcwin32.h.
2578 * Added some explicit type casts for inline code since MSVC
2579 require them. Affected files lib/silcutil/silcbuffer.h,
2580 lib/trq/silcdlist.h and lib/trq/silclist.h.
2582 * Print warning in log files from now on if the packet
2583 decryption fails. Affected file silcd/server.c.
2585 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2587 * Changed the `say' client operation's interface to accept
2588 new `type' argument to indicate the type of the message sent
2589 by the library. The application may filter the library's
2590 messages according the type. The affected file is the
2591 lib/silcclient/silcapi.h.
2593 * Added two new functions to lib/silcclient/silcapi.h:
2594 silc_client_del_client and silc_client_del_client_by_id.
2595 Affected file lib/silcclient/idlist.c.
2597 * Moved the clientincludes.h from includes/ to silc/ and
2598 serverincludes.h from includes/ to silcd/.
2600 * The modes for the CMODE and CUMODE are now passed as
2601 uint32 for application with COMMAND_REPLY. The affected
2602 file is lib/silcclient/command_reply.c.
2604 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2606 * /WHOIS without arguments shows client's own information.
2607 Affected file lib/silcclient/command.c.
2609 * Changed PING to not accept any arguments. The specs
2610 says that client can ping only the connected server so
2611 requiring an argument is not needed. Affected file is
2612 lib/silcclient/command.c.
2614 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2616 * Fixed a fatal bug in private message sending and reception
2617 encryption and decryption when using private message keys.
2618 The implementation was incorrect and did not follow the
2619 specification. It causd that some of the message were
2620 lost since it did not use the sending and receiving keys
2621 as the protocol suggests. This has been fixed and will cause
2622 incompatibilities with older clients when sending private
2623 message encrypted with private message keys. Affected files
2624 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2625 and various other in Irssi SILC Client.
2627 Added `responder' boolean argument to the functions
2628 silc_client_add_private_message_key[_ske] to indicate when
2629 the key is added as responder or initiator of the key
2632 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2634 * Removed the silc_ske_check_version function and created
2635 a SilcSKECheckVersion callback. Added also a function
2636 silc_ske_set_callbacks that is now used to set all SKE
2637 callbacks. The callback functions are not given to
2638 the SKE functions anymore, but this function is used to
2641 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2643 * Added `silc_version' argument to the silc_client_alloc
2644 to define the version of the application for the library.
2645 The library will use the version string to compare it
2646 against the remote host's (usually a server) version
2647 string. Affected file lib/silcclient/silcapi.h
2649 * Added the KE protocol context to Key Agreement context
2650 in client library so that we can abort the SKE if it
2651 is in process when we get timeout. Affected file is
2652 lib/silcclient/client_keyagr.c.
2654 * Do not resolve the client ID forever if it returns in the
2655 first time that such client does not exist. This was done
2656 for example with private message. Affected file is
2657 lib/silcclient/client_prvmsg.c.
2659 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2661 * Do not add regex.h for WIN32. The affected file
2662 includes/silcincludes.h.
2664 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2665 not work yet 100%. It generates the DLL's automatically
2666 when compiling with --with-win32 under cygwin.
2668 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2670 * lib/contrib/regex.c is not compiled on WIN32.
2672 * Added silc_net_get_socket_opt function to the
2673 lib/silcutil/silcnet.h.
2675 * Added includes/silcwin32.h for WIN32 specific includes
2678 * Do not use ptime structure or any of the posix process
2679 functions on WIN32 in lib/silccrypt/silrng.c.
2681 * Added silc_gettimeofday to provide generic function
2682 for struct timeval on all platforms. Added the function
2683 to lib/silcutil/silcutil.h.
2685 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2687 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2688 library as they clearly belong there. As a plus side we
2689 can make the actual socket connection routines platform
2692 Added also new generic function silc_socket_read and
2693 silc_socket_write (that used to be silc_packet_[read/write].
2694 The implementation of these are platform specific.
2696 * Added WIN32 specific routines of silc_socket_[read/write]
2697 to lib/silcutil/win32/silcwin32sockconn.c.
2699 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2701 * Added preliminary support for native WIN32 compilation under
2702 cygwin (using the -mno-cygwin option for GCC) to the
2703 ./configure.in.pre. The --with-win32 now prepares the
2704 compilation for native WIN32.
2706 * Rewrote the SILC Scheduler interface in the file
2707 lib/silcutil/silcschedule.h. The scheduler is now context
2708 based and does not have anymore any global static scheduler.
2709 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2710 and created lib/silcutil/win32 directory for WIN32 based
2713 * Added Unix specific network routines to the
2714 lib/silcutil/unix/silcunixnet.c and the old
2715 lib/silcutil/silcnet.c includes now only generic routines.
2717 Added WIN32 specific network routines to the
2718 lib/silcutil/win32/silcwin32net.c.
2720 * Added Unix specific utility functions from the
2721 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2723 * Added WIN32 SILC Scheduler to the file
2724 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2727 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2729 * Do not handle JOIN notify in the server if the target client
2730 is not registered (idata->registered == FALSE). The affected
2731 file is silcd/packet_receive.c.
2733 * Update the nickrec->founder in event_cumode in the Irssi SILC
2734 client. Affected file irssi/src/silc/core/silc-channels.c.
2736 * Fixed the CUMODE_CHANGE notify handling in the server when
2737 server and router are announcing their clients on channels.
2738 Now the mode changes are saved and notified correctly. The
2739 affected file is /silcd/packet_receive.c.
2741 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2742 They really did not replace the cache entry in the ID Cache.
2743 Now they do that. Affected file silcd/idlist.c.
2745 * Fixed the KICK notify handling in the Irssi SILC client to
2746 update the channel records so that the kicked client does not
2747 appear to be on the channel. The affected file is
2748 irssi/src/silc/core/silc-channels.c.
2750 * Always update the conn->current_channel when executing command
2751 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2753 * Fixed the KILL notify handling in Irssi SILC client to remove
2754 the killed client on all channels.
2756 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2758 * Fixed the silc_parse_command_line to remove extra spaces
2759 from the start and end of the arguments. Affected file is
2760 lib/silcutil/silcutil.c.
2762 * Cancel and free any active protocol in the function
2763 silc_server_close_connection. Affected file silcd/server.c.
2765 * Cancel and free any active protocol in the function
2766 silc_client_close_connction. Affected file is
2767 lib/silcclient/client.c.
2769 * Do not execute the KILL command for clients that are in
2770 history (ie. they are not in the network). Affected file is
2773 * Fixed KILL notify handling, client does not crash anymore.
2774 Affected file irssi/src/silc/core/silc-channels.c.
2776 * Reduced the default packet buffer size from 2048 to 1024 in
2777 lib/silccore/silcpacket.c.
2779 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2780 counter to the SKE context that is incresed when the SKE library
2781 performs async operation outside the library. If the outside
2782 process frees the SKE context and FREED status will be set
2783 and the library will detect after the sync operation that the
2784 libary is freed. The affected files are
2785 lib/silcske/silcske[_status].[ch].
2787 * Resolve the client entry information in the function
2788 silc_client_channel_message to assure that NULL pointer is not
2789 passed as client entry to the application. */
2791 * Fixed the task timeout calculation to assure that there is
2792 never negative timeouts. The affected file is
2793 lib/silcutil/silcschedule.c.
2795 * Fixed the channel user mode notification sending in server.
2796 It was sent point-to-point to the router (or to server by router)
2797 but it needs to be destined to a channel. The routines now
2798 supports sending the channel user mode notifys to the channels
2799 when announcing clients and channels. Affected files are
2800 silcd/server.c and silcd/packet_receive.c.
2802 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2803 It did not actually replace the old channel entry in the cache.
2804 Affected file lib/silcclient/client_notify.c.
2806 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2808 * Fixed a possible crash in silc_packet_send_prepare. It now
2809 assures always that there is enough space in the buffer and
2810 at the tail area of the buffer (for MAC).
2812 Fixed the inbound buffer reallocation in silc_packet_read.
2813 It was old code and did not handle the reallocation correctly.
2816 The affected file is lib/silccore/silcpacket.c.
2818 * Fixed buffer overflow in silc_parse_nickname in the file
2819 lib/silcutil/silcutil.c.
2821 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2823 * make install generates new server keys only if there is not
2826 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2828 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2829 Added check that if the NOREPLY is set then we will not send
2830 the away message. This avoids infinite loop of away messages
2831 if both clients are away. The affected file is
2832 lib/silcclient/client_prvmsg.c.
2834 * Fixed client crash if /NICK was given without arguments.
2835 Affected file lib/silcclient/command.c.
2837 * Server does not send the invite list in INVITE command back
2838 to the client if the list was not altered. Added this notion
2839 to the protocol spec as well. Affected file silcd/command.c.
2841 Fixed possible crash in INVITE command by checking the
2842 value of silc_server_get_client_route command.
2844 * Fixed the INVITE notify type handling. The arguments are now
2845 taken in correct order and client does not crash. The affected
2846 file is irssi/src/silc/core/silc-channels.c.
2848 Removed the "Inviting xxx to channel" message from the
2849 client library away and let the application handle it.
2850 Affected file lib/silcclient/command.c. Added that message
2851 to Irssi SILC client's message formats.
2853 * Fixed CMODE command crash in client. It now checks the
2854 amount of arguments correctly and does not crash. The affected
2855 file is lib/silcclient/command.c.
2857 * Do not create new channel automatically in silc_channels_join
2858 but check whether the channel by that name already exists.
2859 Affected file irssi/silc/core/silc-channels.c.
2861 * Do not send the SERVER_SIGNOFF to router if the disconnected
2862 entity was the router. Affected file silcd/server.c.
2864 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2865 SILC client as it was missing from there.
2867 Added the handling of the KICK notify to the Irssi SILC client
2868 as it was missing. Added "you have been kicked" message to
2869 Irssi SILC client's message modules formats.
2871 Added the handing of the KILL notify to the Irssi SILC client
2872 as it was missing. Added the kill message module formats
2875 The affected file is irssi/src/silc/core/silc-channels.c.
2877 * The router did not save the channel mode the server announced.
2878 Affected file silcd/packet_receive.c.
2880 * Fixed a possible crash in INFO command in server. If the
2881 server did not provide the server info it crashed. Affected
2882 file silcd/command.c.
2884 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2886 * Fixed the GETKEY command in the server to check also the
2887 global list. Otherwise the GETKEY would not work correctly
2888 in normal SILC server. Affected file silcd/command.c.
2890 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2892 * Fixed GETKEY crash, it crashed if the command did not succseed.
2894 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2896 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2897 is now real and not just an macro interface to GMP.
2899 Removed the entire GMP from the source tree and imported new
2900 NSS MPI library instead. Reason for removing GMP is that it is
2901 extremely large and compiles extremely slow. The NSS MPI
2902 is only a few files and compiles in less than 10 seconds.
2903 The speed is also about the same as GMP. The MPI is imported
2904 to lib/silcmath/mpi.
2906 If the system has GMP installed we will still use the GMP.
2907 If it is not then the NSS MPI will be compiled.
2909 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2911 * Merged a long nickname (127 characters long) crash bugfix from
2912 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2914 * Merged a freed memory reference bugfix from Irssi CVS tree.
2915 Affected file irssi/src/core/commands.c.
2917 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2919 * Added the server's public key sving and verification to the
2920 server when performing the SKE. This was missing and the
2921 remote server's (or router's) public key was accepted without
2922 checking whether we have it previously or trust it at all.
2923 Affected file silcd/protocol.c.
2925 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2927 * Check in the silc_server_timeout_remote if protocol is active
2928 and make sure that the protocol's final callback is called so
2929 that all memory if freed. Affected file silcd/server.c.
2931 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2933 * silc_server_whois_send_reply crashed the server if the nickname
2934 was 127 characters long. Affected file silcd/command.c.
2936 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2938 * Added sanity check to the silc_server_new_client. If the hostname
2939 is provided inside username then check that the provided hostname
2940 really is the same as the resolved one. If the hostname was not
2941 resolved then check it from the public key. Affected file is
2942 silcd/packet_receive.c.
2944 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2945 if the server disconnected us and the connection is not valid
2946 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2948 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2949 the library to the lib/silcutil/silcutil.[ch].
2951 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2953 * Close log file after open. Affected file
2954 lib/silcutil/silclog.c.
2956 * Check whether sock == NULL in silc_client_send_packet and return
2957 if it is. Affected file lib/silcclient/silcclient.c.
2959 * Check rec->entry == NULL in the Irssi SILC Client before
2960 sending the channel message. Affecte file is
2961 irssi/src/silc/core/silc-servers.c.
2963 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2965 * Merged a splitted window bugfix from Irssi CVS tree. The
2966 affected file is irssi/src/fe-text/textbuffer-view.c.
2968 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2969 It did not print nickname.
2971 * Improved the distributions system a bit.
2973 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2975 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2976 irssi/src/fe-text/gui-window.c.
2978 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2979 to in-active server. The affected file is
2980 irssi/src/silc/core/client_ops.c.
2982 * Resolve the client in USERS command reply if the entry does
2983 not have username resolved. The affected file is
2984 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2985 command to WHOIS command to really resolve stuff. The USERS
2986 is not used any more in any critical section so WHOIS can
2987 be used even though it might be slower than IDENTIFY.
2989 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2992 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2994 * Changed the protocol API a bit more consistent in the
2995 lib/silccore/silcprotocol.[ch].
2997 * Changed the following headers to ROBODoc format:
2999 lib/silccore/silcpayload.h
3000 lib/silccore/silcprotocol.h
3001 lib/silccore/silcsockconn.h
3003 All core library headers are now formatted.
3005 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Fixed a bug in Irssi SILC client; do not show that you are
3008 server/router operator if you really are not. Affected file is
3009 irssi/src/silc/core/client_ops.c.
3011 * Renamed silc_command_free_payload to silc_command_payload_free.
3012 Affected file lib/silccore/silccommand.h
3014 * Added silcmath.h to include the prototoypes of various routines
3015 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3018 * Changed the following headers to ROBODoc format:
3020 lib/silccore/silcchannel.h
3021 lib/silccore/silccommand.h
3022 lib/silccore/silcid.h
3023 lib/silccore/silcidcache.h
3024 lib/silccore/silcmode.h
3025 lib/silccore/silcnotify.h
3026 lib/silccore/silcpacket.h
3027 lib/silcmath/silcmath.h
3029 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3031 * Added checking to the server code not to start the server if
3032 ciphers and stuff are not configured properly. Affected files
3033 silcd/serverconfig.[h] and silcd/server.c.
3035 * Changed the layout of the header files of the public interfaces
3036 in the SILC libraries. The new layout supports ROBODoc
3037 documentation tool (and some others) so that it is easy to create
3038 a library reference manual. All the other headers and source
3039 code must still follow the CodingStyle document. Also source
3040 code must not include these ROBODoc stuffs, only the headers.
3041 Furthermore, all public interface headers must now be named
3042 by using `silc' prefix, example: silcapi.h, silccipher.h.
3043 Some files were renamed due to this. All the other headers
3044 must not be used as public interfaces. I will update the
3045 CodingStyle document later. Changed following headers, so far:
3047 lib/silcclient/silcapi.h
3048 lib/silccore/silcauth.h
3049 lib/silccore/silcprivate.h
3050 lib/silccrypt/silcdh.h
3052 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3056 * Removed silc_client_packet_send_flush from the client library
3057 as it is not needed. Affected file lib/silcclient/client.[ch].
3059 * Added printing of message of unresolved authentication method
3060 to the Irssi SILC client. Added it to the module formats.
3061 Removed the same message from the client library.
3063 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3065 * Added new distribution feature, DISTLABEL. Every distribution
3066 can define own preprocessor label that can be used in the
3067 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3068 file distributions, acconfig.h.pre and prepare.
3070 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3072 * Added Makefile.defines_int to include the actual definitions
3073 for Makefile.defines.in. Tested the new distribution system,
3074 created distributions and tested installation.
3076 * Added AWAY message printing to the Irssi SILC client. Added
3077 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3079 * Added SCONNECT command to call the SILC's CONNECT command.
3080 Cannot use CONNECT directly since Irssi uses that internally.
3081 Affected file irssi/src/silc/core/silc-servers.c.
3083 Added ACTION local command. It is same as ME command but takes
3084 the channel as mandatory argument.
3086 Rewrote some of the Irssi's help files to suite for SILC
3089 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3091 * Added Makefile.defines[.in] that should for now on be included
3092 in all Makefile.am file in the source tree. That file includes
3093 all common compilation definitions for SILC source tree.
3095 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3097 * Minor changes to the ./prepare script to change the package
3098 name according the distribution name to the configure.in.
3100 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3102 * Created new distribution system. Added file `distributions'
3103 that defines all the distributions that can be created out of
3104 the SILC source tree. The ./prepare script now reads that
3105 file to determine how to prepare the distributions. The
3106 first argument to the ./prepare is the name of the distribution
3107 and second is the version of the distribution. If given
3108 without arguments it creates the default (toolkit) distribution
3109 with the default version (defined in ./prepare).
3111 All Makefile.am files that are subject to the distributions
3112 are now named as Makefile.am.pre. These are ./Makefile.am
3113 and lib/Makefile.am. Others may be changed later.
3115 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3117 * Added invite list, ban list, some key management and connection
3118 error message printing to module formats in the Irssi SILC client.
3120 * Added new silc_client_set_away_message to set the away message
3121 that is back to the person who sent private message. The
3122 affected file lib/silcclient/silcapi.h and the
3123 lib/silcclient/client_prvmsg.c.
3125 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3127 * Fixed the private message sending in the Irssi SILC client,
3128 added local command KEY to the Irssi SILC client.
3130 Added key management and key agreement message formats to the
3131 irssi/src/fe-common/silc/module-formats.[ch].
3133 Added USERS (alias WHO) printing, server/router operator
3134 indication and LIST command printing to the module formats.
3136 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3138 * Fixed channel joining notify handling, cumode notify handling
3139 from Irssi SILC client.
3141 * Added SILC specific module-formats to the Irssi SILC client so
3142 that SILC specific message hilighting, colors etc is possible.
3143 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3145 Added channel mode, channel user mode, actions, notices,
3146 whois and whowas printing to the the module-formats.c.
3148 * Fixed a bug in channel deletion in the server. The channel
3149 is not left to the cache even if the channel founder auth mode
3150 is set when there are no users anymore on the channel. Affected
3151 file silcd/server.c.
3153 * The silc_net_localhost now resolves the entire hostname including
3154 the domain name. Affected file lib/silcutil/silcnet.c.
3156 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3158 * Changed the ask_passphrase client operation to be ascynchronous.
3159 It has now a completion callback and a context that the
3160 application must call after it has got the passphrase from
3161 the user. Affected files lib/silcclient/silcapi.h,
3162 lib/silcclient/protocol.c, lib/silcclient/command.c and
3165 Added SilcAskPassphrase callback that the application calls
3166 to deliver the passphrase to the library.
3168 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3169 The public key verification and especially a certificate
3170 verification is asynchronous procedure.
3172 Added new SILC_SKE_STATUS_PENDING status to indicate the
3173 request is pending and a callback will be called to finalize
3176 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3177 indicate that remote end did not send its public key (or
3178 certificate), even though we require it. Added check for this
3179 condition in the SKE. This was a security bug, now fixed.
3181 Defined new SilcSKEVerifyCbCompletion callback that is called
3182 when the verification process is completed.
3184 The affected files lib/silcske/silcske_status.h and
3185 lib/silcske/silcske.[ch].
3187 * Changed the verify_public_key client operation to be async
3188 as well. Defined SilcVerifyPublicKey callback that is used to
3189 indicate the success of the public key verification process.
3191 Changed the server and client to use the new async client
3194 * Changed the Irssi SILC client's internal scheduler to be called
3195 twice as many times as it used to be. As a result the client
3196 should be a bit faster now. Affected file is
3197 irssi/src/silc/core/silc-core.c.
3199 * Added support to Irssi SILC client of asynchronous public key
3200 verification and passphrase inquiry. Affected file is
3201 irssi/src/silc/core/silc-core.c.
3203 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3205 * Do not say "You have left channel %s" in client library.
3206 Moved it to the application. Affected files are
3207 lib/silcclient/command.c and silc/client_ops.c.
3209 * Fixed silc_client_get_clients. Command context was not
3210 duplicated and was freed memory in the callback. Affected
3211 file lib/silcclient/idlist.c.
3213 * Do not say "you are now talking..." on JOIN command in the
3214 client library. The appliation must handle it.
3216 * Do not say ".. changed topic to" in command reply in the
3217 client libary. The application must handle it.
3219 * Fixed TOPIC command sending in the client library.
3221 * Fixed a memory leak in silc_client_command_free in the file
3222 lib/silcclient/command.c.
3224 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3226 * Imported a modified version of Irssi client to the source tree.
3227 The Irssi will be used to create a new client called
3228 Irssi SILC. Imported to irssi/.
3230 Added silc_core_init_finish function to the Irssi. Affected
3231 file irssi/configure.in.
3233 A lot changes in the Makefile.ams around the irssi tree.
3235 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3237 * Do not rehash if the new size is same as the old size of the
3238 hash table, in the silc_hash_table_rehash*. The affected file
3239 lib/silcutil/silchashtable.c.
3241 * Replaced hash_table_del_by_context calls from the server
3242 (when channel->user_list and client->channels) to the
3243 hash_table_del as it is sufficient and faster.
3245 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3247 * Added silc_hash_table_list, silc_hash_table_get and the
3248 SilcHashTableList structure to provide an alternative way to
3249 traverse the hash table. The affected files are
3250 lib/silcutil/silchashtable.[ch].
3252 * Changed the server's idlist routines to use the hash table
3253 routines to optimize the code.
3255 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3257 * Replaced the client entry's `channel' list and channel entry's
3258 `user_list' list to hash tables for optimized lookup. Changed
3259 the code to use the hash table interface around the code.
3260 Affected file lib/silcd/idlist.[ch].
3262 * Added `auto_rehash' boolean argument to the function
3263 silc_hash_table_alloc to indicate whether the hash table should
3264 auto-rehash when it thinks is appropriate time. It will
3265 increase the hash table size if the there is twice as much
3266 entries in the table than the size of the table, and will
3267 decrease the size if there are twice as less entries than
3268 the size of the table.
3270 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3272 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3274 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3276 * silc_idcache_purge_by_context deletes the entry now by context
3277 as it is supposed to do. Affected file lib/silccore/idcache.c.
3279 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3280 client is not anymore valid (WHOWAS givens the info) and not
3281 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3283 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3285 * Removed the `data' and `data_len' arguments from the ID Cache
3286 interfaces and added `name' argument. ID Cache does not handle
3287 anymore the binary data only a names associated with given ID.
3289 * When hashing a Client ID with silc_hash_id the entire ID is
3290 not hashed anymore, instead only the hash of the Client ID is
3291 hashed. This way we can access the Client ID from the cache
3292 with Client ID but with the hash of the ID (which is a hash of
3293 the nickname) as well without any difference in performance.
3295 Added also silc_idcache_find_by_id_one_ext to do one on one
3296 searching when we have the actual ID. Added also function
3297 silc_hash_client_id_compare. The affected files are
3298 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3300 * When hashing the name associated with a ID it is always done
3301 in lowercase. This way we can access the cache without worrying
3302 about case-sensitivity, even though, for example nicknames are
3305 * Fixed a bug in server with channel message sending. It put
3306 wrong ID type as destination ID. The affected file
3307 silcd/packet_send.c.
3309 * silc_idcache_del_by_context now deletes from all hash tables
3310 by context. Affected file lib/silccore/idcache.c.
3312 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3314 * Changed the client library to use the new ID Cache interface.
3315 Changes around the source tree.
3317 * Added silc_hash_table_rehash_ext to rehash with specific
3318 hash function. Affected file lib/silcutil/silchashtable.[ch].
3320 * Added silc_hash_string_compare to compare two strings in the
3321 hash table. Affected file lib/silcutil/silcutil.[ch].
3323 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3325 * Added new function silc_idcache_del_by_context into the
3326 lib/silccore/idcache.[ch].
3328 * Changed the server's ID list routines to use the new ID Cache
3329 interface. Changes around the source tree.
3331 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3333 * Added silc_hash_table_del[_by_context]_ext functions in to the
3334 lib/silcutil/silchashtable.[ch].
3336 Removed silc_hash_table_find_all* routines and added new
3337 silc_hash_table_find_foreach to replace them.
3339 Added silc_hash_table_replace_ext function as extended
3340 replacing function. Separated the simple hash table interface
3341 from the extended hash table interface in the file
3342 lib/silcutil/silchashtable.h.
3344 * Fixed minor bugs and changed it to use some of the new
3345 hash table functions in lib/silccore/idcache.c
3347 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3349 * Added new function silc_hash_table_find_all to return all keys
3350 in the hash table by the specified key. As the hash table is
3351 collision resistant it also makes it possible to have several
3352 duplicate keys in the hash table. This function may be used to
3353 find all of the keys from the hash.
3355 Added user_context arguments to the SilcHashFunction,
3356 SilcHashCompare and SilcHashDestructor to deliver user specified
3359 Added new fuctions silc_hash_table_find[_all]_ext to do
3360 extended lookup with specified hash and compare functions and
3361 specified user contexts.
3363 Added new function silc_hash_table_add_ext to add the key
3364 with specified hash function and user context.
3366 Added new function silc_hash_table_foreach to traverse all
3367 entrys in the hash table. Added SilcHashForeach callback
3370 Added new function silc_hash_table_del_by_context to delete
3371 the entry only if the context associated with the key matches.
3373 Affected files are lib/silcutil/silchashtable.[ch].
3375 * Removed silc_hash_[server/client/channel]_id and added just
3376 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3377 silc_hash_id_compare to compare two ID's using as the hash table
3378 comparison function. Added also silc_hash_data to hash
3379 binary data and silc_hash_data_compare to compare it.
3381 * Removed silc_idlist_find_client_by_hash as it is not needed
3382 anymore. Affected file silcd/idlist.[ch].
3384 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3385 to use internally the SilcHashTable. The new ID Cache is a lot
3386 faster than the old one. Some of the ID Cache interface was also
3387 rewritten and obsolete and stupid functions were removed.
3389 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3391 * Added entry_count field to the SilcHashTable to keep the number
3392 of the entries in the table. Implemented the function
3393 silc_hash_table_rehash. Added new function
3394 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3396 Fixed a minor bug in silc_hash_table_free.
3398 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3399 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3400 into the lib/silcutil/silcutil.[ch].
3402 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3404 * Implemented a collision resistant hash table into the
3405 lib/silcutil/silchashtable[ch]. See the header and the source
3406 for the SilcHashTable API.
3408 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3410 * Merged dotconf version 1.0.2 into lib/dotconf.
3412 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3414 * Do not compile anything in lib/silcsim/* if the SIM support
3415 is not enabled. The tree should now compile without problems
3418 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3420 * Compiled the SILC under cygwin. Compiled and tested briefly
3421 without problems. More tests needed. The SIMs didn't compile
3424 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3426 * Fixed possible crash in silc_get_username in the
3427 lib/silcutil/silcutil.c.
3429 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3431 * Fixed a va_arg in silc/client_ops.c.
3433 * Oops, RC5 routines were named AES and caused some problems
3434 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3436 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3438 * Added new SilcIDIP structure into the lib/silccore/id.h and
3439 replaced the old `ip' fields from all SILC ID's to that type.
3440 This is a step towards IPv6 support.
3442 The silc_id_get_len takes now the ID as an extra argument.
3443 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3444 both IPv4 and IPv6 based ID's.
3446 The affected files are lib/silccore/id.[ch] and other files
3447 around the tree using these routines.
3449 * Removed the ID length arguments in server from various
3450 silc_server_send_notify_* routines -> they are not needed
3453 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3455 * Fixed memory leak in silc_encode_pem_file in the file
3456 lib/silcutil/silcutil.c.
3458 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3460 * Check minor version as well in the SKE. Affected files are
3461 silcd/protocol.c and lib/silcclient/protocol.c.
3463 * Added --identifier option to the server so that an identifier
3464 can be when creating the public key for the server. Affected
3465 file is silcd/silcd.c.
3467 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3468 lib/silccrypt/silcpkcs.c.
3470 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3472 * Register default ciphers and stuff when using -C option with
3473 the server. Affected file sildc/silcd.c.
3475 * Put back the servers public key filename format, it is better
3476 than the new one. For now, the client keys are saved with the
3477 new filename format. The affected file silc/client_ops.c.
3479 * Implemented the Cipher API for the rest of the ciphers that
3480 did not implement it or implemented it the wrong way.
3482 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3484 * Register default ciphers and stuff when using the -S option
3485 in the client. Affected file silc/silc.c. Same also when
3486 creating new key pair with -C option.
3488 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3490 * Fixed the silc_verify_public_key client operation function to
3491 save the public keys differently. The fingerprint is now
3492 used as filename and not the hostname. This way also the
3493 client keys are saved uniquely and not with hostnames. The
3494 affected file is silc/client_ops.c.
3496 * Trimmed the silc_hash_fingerprint function to remove extra
3497 whitespaces from the end of the fingerprint. The affected
3498 file is lib/silccrypt/silchash.c.
3502 * Added silc_cipher_register_default function to register all
3503 default ciphers. It can be used when configuration files
3504 does not exist and the application does not want any specific
3505 ciphers in any specific order.
3507 The SilcDList is now used as silc_cipher_list dynamically
3508 allocated cipher list. Removed the static list all together
3509 and now all ciphers must be allocated to the dynamic list.
3510 The silc_cipher_alloc routine was changed to check only the
3513 All silc_cipher_* routines that used to return int returns
3516 The affected files lib/silccrypt/silccrypt.[ch].
3518 * The same thing was done to silc_hash_* as for silc_cipher_*
3519 routines. Affected files lib/silccrypt/silchash.[ch].
3521 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3522 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3523 Added also silc_pkcs_[un]register[_default] functions.
3524 Removed the data_context from the PKCS API.
3526 * Added silc_hmac_register_default function to register default
3527 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3528 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3529 to unregister all hmacs at once.
3531 * Register the default ciphers, hash functions, PKCSs and HMACs
3532 if client's configuration file does not exist. The affected
3535 * The client did not load the hash functions from the SIM
3536 modules at all. Added support for this. Affected file is
3537 silc/clientconfig.c.
3539 * When decoding public key with silc_pkcs_public_key_decode, check
3540 the supported algorithm only if PKCS are registered. Affected
3541 file lib/silccrypt/silcpkcs.c. The same was done with the
3542 silc_pkcs_private_key_decode.
3544 * Fixed the SILC List routines to keep the list always in order.
3545 It used to change the list's order when traversing the list but
3546 not it preserves the order. Affected file lib/trq/silclist.h.
3548 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3550 * Added the client library to use the SilcSocketConnection's
3551 reference counter (by silc_socket_dup) to prevent the bug that
3552 the socket object may be freed underneath async operation.
3554 * The name resolv library checking fixes in the configure.in.pre.
3557 * Created new version of the protocol drafts for future
3558 development. The -03 drafts are the ones that will be changed
3559 in the trunk now and the -02 will remain as they are.
3561 * Send list of CUMODE notifys to the router when announcing
3562 the channel users to the router. Affected file silcd/server.c.
3563 If the router receiving channel founder CUMODE for a channel
3564 that already has channel founder it will send CUMODE notify
3565 to the sender to remove the channel founder rights from the
3566 announced client. Affected file silcd/packet_receive.c.
3568 * The CUMODE notify may now use Server ID as well as the entity
3569 who changes the mode. Updated protocool specs.
3571 * Updated INSTALL and README files.
3573 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3575 * New web pages in the http://silc.pspt.fi. The pages was
3580 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3582 * Implemented the [DenyConnectin] config section in the server.
3583 Added silc_server_config_denied_conn to check whether incoming
3584 connection is denied. Affected file silcd/serverconfig.[ch].
3586 * Do not check the ports when checking the incoming configuration
3587 data if the port is 0, meaning any. Affected file is
3588 silcd/serverconfig.c.
3590 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3592 * Fixed buffer overflow in silc_string_compare in the file
3593 lib/silcutil/silcutil.c.
3595 * Fixed double free in silc_server_command_leave in the file
3598 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3600 * Fixed the version checking in the server. Affected file is
3603 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * Fixed the configuration data fetching when accepting new
3606 connections in the server. Affected file silcd/server.c.
3608 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3610 * Added `sender_entry' argument to the function
3611 silc_server_packet_relay_to_channel so that we can check
3612 whether some destination actually belongs to the same route
3613 the sender belongs (ie, we must not resend the packet to the
3614 sender). Affected file silcd/packet_send.[ch].
3616 * Added `servername' field to the SilcClientEntry in the server
3617 to hold the name of the server where client is from. Affected
3618 file is silcd/idlist.h.
3620 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * Moved the channel message encrypting in the router betwen
3623 router connections from silc_server_channel_message to the
3624 silc_server_packet_relay_to_channel since we want to check
3625 whether we have anybody channel before encrypting anything.
3626 Affected files silcd/packet_[receive/send].c.
3628 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * Fixed the [AdminConnection] server config section to support
3631 multiple entries. Affected file silcd/serverconfig.c.
3633 * Added support into the server to check the validity of the
3634 incoming connection before executing any KE or authentication
3637 * The connection configuration is now saved to the KE and
3638 connection auth protocol contexts and not fetched anymore in
3639 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3641 * The local hosts listenning address and port is also resolved
3642 now when starting the server. We want to have the socket object
3643 to include the real address and port for the listener. Added
3644 new function silc_net_check_local_by_sock into the files
3645 lib/silcutil/silcnet.[ch].
3647 * Fixed a broadcast bug in server -> do not broadcast if we
3650 * Fixed a routing bug. Do not route broadcast packets ever.
3651 Broadcast packets must be processed always and not routed since
3652 they may be destined to some other host than yourself and thus
3653 would get routed without no good reason. Affected file is
3656 * Added function silc_server_config_is_primary_route to check
3657 whether primary router connection has been configured (a router
3658 configuration that we are initiating). If there is not, we
3659 will assume that there is only two routers in the SILC network
3660 and we will use the incoming router connection as our primary
3661 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3663 * Changed the order of the broadcasting. Broadcast _after_ the
3664 packet has been processed not before. Affected file is
3667 * Fixed a [ClientConnection] parsing bug. The port was never
3668 parsed correctly thus resulting to port 0. Affected file
3669 silcd/serverconfig.c.
3671 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3672 argument and did not set the broadcast packet flag. Affected
3673 file silcd/packet_send.c. Fixed same bug in the function
3674 silc_server_send_notify as well.
3676 * If we receive NEW_ID packet for our own ID in the server, ignore
3679 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3683 * Removed the nickname from the Private Message Payload.
3684 Updated the code and the protocol specs.
3686 * Updated protocol specs for submitting to the IETF.
3688 * Tweaked the Random Number Generator a bit. Affected file
3689 lib/silccrypt/silcrng.c. Exported a new function
3690 silc_rng_[global]_add_noise which can be used to add more
3693 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3695 * Do not parse packets with different timeout when protocol
3696 is active -> may cause problem with rekey. Affected file
3699 * When server receives signoff notify it must not create
3700 new channel key if the client is on any channels since the
3701 sender of the signoff notify will create it.
3703 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3705 * Added printing of error messages during SKE protocol from the
3706 failure packet sent by server during SKE. Affected file
3709 * Removed the client's failure_callback handling with timeout
3710 and handle it immediately when received.
3712 * The SKE library returned wrong type in SUCCESS and FAILURE
3713 packets. They must be 32 bit MSB not 16 bit MSB.
3715 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3717 * Ok, rewrote the logic of the re-key and now it seems to work.
3718 I tested it on high traffic with frequent re-keys without
3719 problems. Added hmac_receive (and renamed hmac to hmac_send)
3720 in SilcClientConnection in lib/silcclient/client.h and
3721 in SilcIDListData in silcd/idlist.h. Also, removed the
3722 SilcPacketParserContext's cipher and hmac fields as they are
3723 not needed anymore and actually caused some problems when
3724 the ciphers and hmac's changed underneath the packet parser.
3726 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3728 * If re-key protocol is active then process the incoming packets
3729 synchronously since we must assure that icoming packets encrypted
3730 with the old key is processed before the new keys is set to
3731 use. This is true other packets than for REKEY packets.
3732 Affected file silcd/server.c. The same was done to client library
3733 as well, affected file lib/silcclient/client.c.
3735 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3737 * Fixed bug in client and server to accept the force send if
3738 the packet is send from silc_[server/client]_packet_process
3739 function. Otherwise the packets are never delivered, oops.
3741 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3743 * Disable force sending of packets when REKEY protocol is active.
3744 We must assure that no packet is sent directly when rekey is
3745 performed. All packets must be sent through packet queue.
3746 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3747 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3748 function is silc_[server/client]_packet_send_real to check
3751 * Replaced the SIM paths from example config files to
3752 /usr/local/modules. Also, make install creates now
3753 /usr/local/silc/logs directory to hold all the SILC server
3756 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3758 * Made the configure.in.pre work on Solaris. Patch by salo.

3767 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3769 * When MAC computation fails the silc_packet_decrypt returned 0
3770 even though it was supposed to return -1. Fixed this. The
3771 affected file is lib/silccore/silcpacket.c.
3773 * Do not replace the config files in /etc/silc (in make install)
3774 if they already exist. Affected file ./Makefile.am.
3776 * Do not send re-key packets immediately but through packet queue.
3777 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3779 * Changed silc_net_check_host_by_sock to return FALSE if the
3780 IP/DNS could not be resolved. Though, it returns the IP address
3781 now even if it could not resolve it (but returns also FALSE).
3782 Affected file lib/silcutil/silcnet.[ch].
3784 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3786 * Added silc_pkcs_decode_identifier to decode the public key's
3787 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3788 Added also silc_pkcs_free_identifier. Added also new context
3789 SilcPublicKeyIdentifier.
3791 * Added -S option to the silc client. It is used to dump the
3792 contents of the specified public key file.
3794 * Changed the PKCS api to return the public key length when
3795 setting the public key.
3797 * Fixed a fatal bug in the public and private key file loading.
3798 Affected file lib/silccrypt/silcpkcs.c.
3800 * Execute the packet parsing for client with zero (0) timeout
3801 if the protocol is active. Affected file silcd/server.c.
3803 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Made the key generation options to the silcd program. Added
3806 -C option, equivalent to client's option.
3808 * Added new [ServerKeys] config section to the server. It
3809 configures the server's public and private key.
3811 * Defined generic Public Key Payload into the protocol
3812 specification to send specific type of public keys and
3815 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3816 public key or certificate.
3818 * Implemented the GETKEY command to the server and to the
3819 client library and on user interface.
3821 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3823 * Made preliminary `make install' work.
3825 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3827 * Added SilcServerRekey context into silcd/idlist.h.
3829 * Added the PFS support as defined in the specification to the
3830 SKE protocol. Affected files lib/silcske/*.c.
3832 * Added `ske_group' field to the SilcServerRekey context to hold
3833 the number of the SKE group that is used with PFS in re-key.
3834 Affected file silcd/idlist.h.
3836 * Added PFS re-key support to the server. Affected file is
3839 * Added silc_protocol_cancel to cancel execution of the next
3840 state of the protocol. Affected file is
3841 lib/silccore/silcprotocol.[ch].
3843 * Added the re-key support with and without PFS to the client
3844 library. Re-key is performed once in an hour, by default.
3846 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3847 Added silc_client_rekey_callback and silc_client_rekey_final.
3848 Affected files are lib/silcclient/protocol.[ch] and
3849 lib/silcclient/client.[ch].
3851 * Removed the `hmac_key' and `hmac_key_len' fields from the
3852 SilcClientConnection structure; not needed. Affected file is
3853 lib/silcclient/client.h.
3857 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3859 * Do not ask whether user wants to use the negotiated private key
3860 for private messages, just use it. Affected file is
3861 silc/local_command.c.
3863 * Added `send_enc_key' and `enc_key_len' fields to the
3864 SilcIDListData structure since they are needed in the re-key
3865 phase. Affected file is silcd/idlist.[ch].
3867 * Implemented the simple re-key protocol into the server.
3868 Affected files silcd/server.c and silcd/protocol.[ch]. The
3869 re-key will be performed once in an hour, by default.
3871 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3872 Added silc_server_rekey, silc_server_rekey_callback and
3873 silc_server_rekey_final.
3875 * Removed Tunneled flag from the protocol. Updated the code
3876 and the specifications.
3878 * Adde `pfs' field to the SilcIDListData to indicate whether
3879 the PFS is to be performed in the re-key. Affected file is
3882 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3884 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3885 int64 of at least the xintXX size. If void * is less that 4
3886 bytes uint32 * will be used. Defined bool as boolean.
3888 * Changed _ALL_ unsigned long and unsigned int to uint32,
3889 unsgined short to uint16 in the source tree.
3891 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3892 not handle clients that has entry->data.registered == FALSE.
3893 They are not in the network anymore. Affected file is
3896 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3898 * Implemented the sending of the SERVER_SIGNOFF notify in the
3899 server. Affected file is silcd/server.c.
3901 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3902 Added also silc_notify_payload_encode_args into the
3903 lib/silccore/silcnotify.[ch].
3905 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3906 Affected file silcd/packet_receive.c.
3908 * Implemented the SERVER_SIGNOFF notify handling in the client
3909 library. Affected file lib/silcclient/client_notify.c. Also,
3910 implemnted the printing of the SERVER_SIGNOFF info to the
3911 application. Affected file silc/client_ops.c.
3913 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3914 if the deleting was successful. Affected file silcd/idlist.[ch].
3916 * Added support for public key authentication in the connection
3917 authentication protocol in the client library. Affected file
3918 lib/silcclient/protocol.c.
3920 * Changed the server's silc_idlist_get_clients_by_* interface
3921 to support already allocated array so that new entries may be
3922 added to pre-allocated array. Affected file silcd/idlist.[ch].
3923 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3924 and command replies.
3926 * All command reply functions in the server now calls the
3927 pending command callback even if error occured. This way the
3928 error will be delivered to the client as well. Affected files
3929 silcd/command.c and silcd/command_reply.c.
3931 * Fixed INFO command to return local server's info if no server
3932 was provided. Affected file lib/silcclient/command.c.
3934 * Removed RESTART command for good. Updated the code and the
3937 * Rewrote parts of the task system. It is a bit simpler now.
3938 Removed unsued task priorities. The affected files are
3939 lib/silcutil/silctask.[ch].
3941 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3943 * Moved the USERS printing from the library to the application.
3944 Affected files lib/silcclient/command.c and silc/client_ops.c.
3946 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3950 * Added channel key re-key support. The re-key is perfomed
3951 only by the router and is done once in an hour. Added `rekey'
3952 field to the SilcChannelEntry in the server. Affected files
3953 silcd/server.c and silcd/idlist.h.
3955 * Added silc_task_unregister_by_context into the file
3956 lib/silcutil/silctask.[ch].
3958 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3960 * Added SILC_UMODE_GONE mode to indicate when the client is not
3961 present in the SILC network. Added also support to the local
3962 command AWAY that will set this mode. Added support of showing
3963 "xxx is gone" in WHOIS command. The USERS command shows the
3964 gone status as well.
3966 * Fixed setting server and router operator privileges in the
3967 server's UMODE command. Affected file silcd/command.c.
3969 * Merged the SKE KE1 and KE2 payloads into one payload. The
3970 new KE payload is equivalent to the old KE2 payload.
3972 Cleaned up the SKE Start Payload parsing. It now uses the
3973 simple buffer unformatting to do the parsing. A lot faster
3976 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3977 to the SKE that is used to indicate whether both of the SKE
3978 parties should perform authentication. By default only the
3979 responder performs authentication. By setting this flag also
3980 the initiator must do authentication. By default it is unset
3981 since in normal SKE case, client to server connection, only
3982 the responder should do authentication. When doing SKE between
3983 two clients both should perform authentication. Updated the
3984 code and the protocol specs.
3986 * A little fix to IDENTIFY command in the server. Search the
3987 client first by hash not nickname. Affected file is
3990 * Fixed the silc_client_close_connection to support closing
3991 the client to client connections wihtout deleting too much
3992 data. Affected file lib/silcclient/client.c.
3994 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3995 are received if protocol used to be active but is not anymore
3996 the application would crash due to NULL pointer dereference.
3997 Affected files silcd/server.c and lib/silcclient/client.c.
3999 * Added `hash' field to the SilcClientConnection to include
4000 the hash function negotiated in the SKE protocol.
4002 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4003 to set the channel founder authentication data. A client can
4004 claim the founder rights later by providing the authentication
4005 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4006 This way the channel founder can regain the channel founder
4007 privileges even it is left the channel. This works only on
4008 local server and the client must be connected to the same
4009 server to be able to regain the founder rights. Updated the
4010 protocol specs accordingly.
4012 Added support to the CMODE command in the client to set the
4013 founder auth data. Read the README to see how to set it.
4015 Added support to the CUMODE command to claim the founder
4016 rights. Read the README to see how to do it.
4018 Added support for the founder authentication to the Channel
4019 Entry in the server. Affected file silcd/idlist.h.
4021 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4022 server's CMODE command. Affected file silcd/command.c.
4024 * Added the following new functions into lib/silccore/silcauth.[ch]:
4025 silc_auth_get_method and silc_auth_get_data.
4027 * The server now saves the remote hosts public key to the
4028 SilcIDListData pointer. Affected file silcd/protocol.c.
4030 * The normal server now does not remove the channel entry from
4031 the cache if the founder authentication data is set. It used
4032 to remove it if the founder was the last one on the channel on
4033 the server and left the channel. The auth data is saved and
4034 if the channel is re-joined later the old entry is used with
4035 the old auth data. Affected files silcd/command_reply.c and
4038 * Removed the `pkcs' field from the SilcIDListData structure
4039 in the server; it is not used. Affected file silcd/idlist.h.
4041 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4043 * Fixed packet processing on slow links. Partial packets were
4044 never re-processed because the incoming data buffer was cleared
4045 by the application. Application must not directly clear the
4046 sock->inbuf, the packet processing routines handle it. Fixed
4047 this in client library and in server.
4049 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4051 * Fixed the WHOIS and IDENTIFY send reply function to really
4052 check whether to send list or just one entry. Affected file
4055 * Cleaned up the LEAVE command's channel key distribution. The
4056 affected file silcd/command.c.
4058 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4059 can enforce the channel mode as well. In that case the ID
4060 includes the ID of the server. The code now enforces the
4061 mode change if the router have different mode than the server.
4063 * The notify client operation with CMODE_CHANGE notify can now
4064 return NULL client_entry pointer if the CMODE was not changed
4065 by client. Application must check for this.
4067 * Added <Server ID> argument to INFO command to support server
4068 info fetching by Server ID.
4070 * Added silc_server_announce_get_channel_users to get assembled
4071 packets of channel users of the specified channel. Affected
4072 file silcd/server.[ch].
4074 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4075 was freed underneath the ID Cache.
4077 * Re-announce clients when the server received CHANNEL_CHANGE
4078 notify from the router. Affected file silcd/packet_send.c.
4080 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4082 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4083 crashed since it did not handle the fact that there is no cipher
4084 called "3" and didn't check the error condition. Now fixed.
4086 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4087 flag. It can be used to send message requests.
4089 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4091 * Implemented the RESTART command in the client.
4093 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4094 notice type messages. Added notice printing to the user
4097 * The channel keys are not re-generated if the channel's mode
4098 is PRIVKEY, ie private key on the channel exists. Affected
4099 files silcd/server.c and silcd/command.c.
4101 * Fixed a little bug in channel message delivery when channel
4102 private keys are set in the server. Affected file is
4103 silcd/packet_send.c.
4105 * Changed the setting on channel->on_channel = TRUE from the
4106 silc_client_save_channel_key to the JOIN command reply. The
4107 key payload is not received if the private channel key is set.
4108 Affected file lib/silcclient/command_reply.c and the
4109 lib/silcclient/client_channel.c.
4111 * When the CMODE_CHANGE notify is sent and the channel private
4112 key mode is removed the channel key must be re-generated in
4113 other cells as well. Added this support for the router in the
4114 silcd/packet_receive.c.
4116 * Added new local command NOTICE to send notice message on
4117 channel. Affected file silc/local_command.[ch].
4119 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4121 * Added new local command ME to the client. It is used to send
4122 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4123 some action. Affected file silc/local_command.[ch].
4125 * Changed channel_message and private_message client operations
4126 to deliver the message flags to the application. Added also
4127 the `flags' arguments to the silc_client_send_channel_message
4128 and silc_client_send_private_message functions. Affected file
4131 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * Redefined the Private Message Payload to support private message
4134 keys and to support the new private message flags. Updated
4135 the protocol specs. Flags makes it possible to have for example
4136 CTCP style messages.
4138 * Added new type SilcPrivateMessagePayload and defined an API
4139 for it in the lib/silcclient/silcprivate.[ch].
4141 * Tested private message private keys successfully. Tested the
4142 private message key set, unset and list commands with the new
4145 * Redefined the Channel Message Payload to include the channel
4146 message flags (equal with private message flags) to support
4147 for example CTCP style messages.
4149 * Defined some of the message (for channel and private message)
4150 flags. Updated the protocol specs and added the flags to the
4151 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4153 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4155 * Added SilcKeyAgreementStatus type to the key agreement routines
4156 to indicate the current status and error if one occured.
4157 The status types are defined in the lib/silcclient/silcapi.h.
4159 * Added new local command KEY that is used to set and unset private
4160 keys for channels, set and unset private keys for private messages
4161 with remote clients and to send key agreement requests and
4162 negotiate the key agreement protocol with remote client. The
4163 key agreement is supported only to negotiate private message keys,
4164 it currently cannot be used to negotiate private keys for channels,
4165 as it is not convenient for that purpose.
4167 * Fixed a minor pending callback setting bug in the function
4168 silc_client_get_client_by_id_resolve, now the function works.
4169 Affected file lib/silcclient/idlist.c.
4171 * Added function silc_net_get_local_port to get local bound
4172 port by socket. Added to lib/silcutil/silcnet.[ch].
4174 * Added `sockets' and `sockets_count' fields to the SilcClient
4175 object. They hold the sockets of the listenning sockets in
4176 the client. Listenning sockets may be for example the key
4177 agreement server. Affected file lib/silcclient/client.[ch].
4178 Added functions the silc_client_add_socket and the
4179 silc_client_del_socket. They are exported to the application
4182 * Added ~./silc/clientkeys to support other client's public keys.
4184 * Renamed verify_server_key client operation to verify_public_key
4185 and added one argument to indicate the type of the connection
4186 (server, client etc.).
4188 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4190 * Added silc_server_connection_auth_request to handle the
4191 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4192 silcd/packet_receive.[ch].
4194 * Added silc_server_send_connection_auth_request into the
4195 silcd/packet_send.c to send the connection auth request packet.
4197 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4200 * Fixed the public key authentication in responder side in the
4201 server. The `auth_data' pointer includes the SilcPublicKey
4202 not the path to the public key. Affected file silcd/protocol.c.
4204 * Implemented the public key authentication in the initiator side
4205 in the server. Affected file silcd/protocol.c.
4207 * Removed the [RedirectClient] config section from the server
4208 configuration. Is not needed and I don't want to implement it.
4210 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4212 * Cleaned up the CMODE command in the server. It now works
4213 correctly and supports all the modes defined in the protocol.
4214 Affected file is silcd/command.c.
4216 * Added `hmac_name' field to the SilcChannelEntry in the server
4217 to hold the default HMAC of the channel. It can be set when
4218 creating the channel (with JOIN command). Affected files
4221 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4222 type to indicate the change of the current cipher and hmac
4223 on the channel. Client can safely ignore the <cipher> argument
4224 (if it chooses to do so) since the CHANNEL_KEY packet will
4225 force the channel key change anyway. The <hmac> argument is
4226 important since the client is responsible of setting the new
4227 HMAC and the hmac key into use.
4229 * Fixed the CMODE command in the client library as well.
4231 * Tested CMODE command in router environment successfully.
4233 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4235 * Show the version of the remote client (or server) when connecting
4236 to the server. It is logged to the log file. Affected file
4237 is silcd/protocol.c.
4239 * Fixed the KILLED notify handling in the client library. The
4240 client must be removed from all channels when receiving the
4243 Also, do not remove the client entry when giving the KILL
4244 command but when the KILLED notify is received.
4246 * Removed silc_idlist_find_client_by_nickname from the server.
4247 Not needed anymore. Affected files silcd/idlist.[ch].
4249 * Implemented the CHANNEL_CHANGE notify type handling to the
4250 server. Affected file silcd/server.c.
4254 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4256 * Added silc_server_send_notify_invite to send the INVITE
4257 notify between routers.
4259 * Implemented the INVITE command correctly to the server.
4261 * Implemented the INVITE notify type handling in the server.
4263 * Implemented the INVITE command to the client library and on the
4266 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4268 * Added function silc_server_get_client_resolve to find the
4269 client entry by ID from all ID lists and then resolve it
4270 (using WHOIS) if it cannot be found. Affected file is
4273 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4275 * Implemented the BAN command to the client library.
4277 * The JOIN command in the server now checks the invite list
4280 * Changed the silc_command_reply_payload_encode_va and the
4281 silc_command_payload_encode_va to support that if argument is
4282 NULL it ignores and checks the next argument. Affected file
4283 lib/silccore/silccommand.c.
4285 * Added silc_server_send_notify_ban to send the BAN notify
4286 type between routers.
4288 * Chaned the silc_notify_payload_encode to support that if
4289 argument is NULL it ignores and checks the next argument.
4290 Affected file lib/silccore/silcnotify.c.
4292 * Tested ban lists in router environment successfully.
4294 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4296 * Implemented BAN command to the server, in silcd/command.[ch].
4298 * Removed the BAN and INVITE_LIST modes from the CMODE command
4301 * Added function silc_string_match to regex match two strings.
4302 Affected files lib/silcutil/silcutil.[ch].
4304 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4306 * Redefined parts of the SilcChannelEntry in the server to support
4307 the new ban and invite lists.
4309 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Redefined the INVITE command. The same command can be used to
4312 invite individuals to the channel but also to manage the invite
4313 list of the channel (to add to and remove from the invite list).
4314 Updated the protocol specs.
4316 * Added new command SILC_COMMAND_BAN that can be used to manage
4317 the ban list of the channel. Updated the protocol specs.
4319 * Removed the channel modes: the SILC_CMODE_BAN and the
4320 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4321 in the CMODE command. The equivalent features are now available
4322 using INVITE and BAN commands. Updated the protocol specs.
4324 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4325 in the network about change in the current ban list. The notify
4326 type is not used by the client.
4328 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4329 support the invite lists.
4331 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4333 * Added new function silc_string_regexify that converts string
4334 including wildcard characters into regex string that can
4335 be used by the GNU regex library. Added into the file
4336 lib/silcutil/silcutil.[ch].
4338 Added silc_string_regex_combine to combine to regex strings
4339 into one so that they can be used as one regex string by
4340 the GNU regex library. Added into the file
4341 lib/silcutil/silcutil.[ch].
4343 Added silc_string_regex_match to match two strings. It returns
4344 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4346 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4348 * Imported GNU regex to the soruce tree into lib/contrib.
4349 Fixed some compiler warning from the regex.c.
4351 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * Fixed MOTD command in the server to work in router environment.
4355 * Fixed the MOTD command in the client library to support
4356 the server argument in the command.
4358 * Added `nickname_len' argument to the silc_idlist_add_client
4359 in the server, as the `nickname' argument may be binary data
4362 * Added silc_idlist_get_channels to return all channels from
4365 * Implemented LIST command to the server. Affected file is
4368 * Implemented the LIST command to the client library and on the
4371 * Added [<user count>] argument to the LIST command reply.
4372 With private channels the user count is not shown.
4374 * Updated TODO and README.
4376 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4378 * The client entry's data.registered must be TRUE even with
4379 global client entry on global client list. The data.registered
4380 is used to check whether the client is anymore in the network,
4381 for example with WHOWAS command so it must be valid.
4383 * Fixed the WHOWAS command in the server. It now actually works
4384 in router environment. Added function into silcd/command_reply.c
4385 silc_server_command_reply_whowas_save.
4387 * Added silc_idlist_purge function to the silcd/idlist.c
4388 to periodically purge the ID Cache.
4390 * Fixed INFO command in the server. It works now in router
4391 environment. Added <server name> argument to the INFO command
4392 reply. Updated the protocol specs.
4394 * Fixed minor bug in silc_idcache_purge to not purge if the
4395 expire value is zero.
4397 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4398 they were buggy because of the WHOWAS information.
4400 * Fixed local command MSG to handle the async resolving of
4401 the remote client properly. It used to fail the first MSG.
4402 Affected file silc/local_command.c.
4404 * Added `data_len' field to SilcIDCache context.
4406 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4408 * Update TODO. Todo in commands in the server.
4410 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4412 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4413 used by routers as broadcast packet to inform other routers
4414 about the changed user mode.
4416 Implemented the notify handling in the server. Affected file is
4417 silcd/packet_receive.c. Added the function
4418 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4420 * Added new generic Channel Payload and deprecated the New Channel
4421 Payload. The New Channel Payload is now the generic Channel
4424 * Added new argument `mode' to the silc_server_send_new_channel
4425 as it is required in the Channel Payload now.
4427 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4428 and created a new and real SilChannelPayload to represent the
4429 new generic Channel Payload. Implemented the encode/decode
4430 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4432 * Added silc_server_get_client_channel_list to return the list
4433 of channels the client has joined for WHOIS command reply.
4434 Affected file silcd/server.[ch].
4436 * Implemented the channel list sending in the WHOIS command reply
4437 in server and in the client.
4439 Implemented the channel list displaying on the user interface
4440 as well. Affected file silc/client_ops.c.
4442 * Added silc_channel_payload_parse_list to parse list of Channel
4443 Payloads. It returns SilcDList list of SilcChannelPayloads.
4444 Client for example can use this function to parse the list of
4445 channels it receives in the WHOIS command reply. The caller
4446 must free the list by calling silc_channel_payload_list_free.
4447 Affected files lib/silccore/silcchannel.[ch].
4449 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4451 * Added one new argument <user mode> to the WHOIS command reply
4452 to return the mode of the user in SILC. Updated the protocol
4455 Implemented it to the server and client.
4457 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4459 * Fixed the mode printing on the user interface on joining.
4460 Affected file silc/client_ops.c.
4462 * Implemented the UMODE command and user modes in general to the
4463 client library and to the user interface.
4465 * Implemented the UMODE command to the server.
4467 * The server now sends UNKNOWN_COMMAND error status if client sends
4468 unknown command. Affected file silcd/command.c.
4470 * All server commands now handle the command identifier the right
4471 way when sending the command reply to the client. The client can
4472 use to identify the command replies with the identifier.
4474 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4476 * Added silc_server_get_client_route to resolve the route to
4477 the client indicated by the client ID. Affected file is
4480 * Added silc_server_relay_packet as general function to relay
4481 packet to arbitrary destination. This deprecates functions
4482 like _send_private_message_key, _relay_notify etc. Affected
4483 file is silcd/packet_send.[ch].
4485 Removed silc_server_send_key_agreement,
4486 silc_server_send_private_message_key and
4487 silc_server_packet_relay_notify functions from the file
4488 silcd/packet_send.[ch].
4492 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4493 server. Affected file silcd/packet_receive.[ch].
4495 * Implemented the KILL command to the client. Implemented the
4496 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4497 Affected files lib/silcclient/command[_reply].c and
4498 lib/silcclient/client_notify.c. Implemented the KILL notify
4499 printing in the user inteface.
4501 * Fixed a lot silc_parse_nick memory leaks from the client
4502 library in the file lib/silcclient/command.c.
4504 * Changed the silc_server_send_notify_on_channels's `sender'
4505 argument from SilcSocketConnection to SilcClientEntry to
4506 check the sender as entry and not as connection object and not
4507 to send to the client provided as argument. The affected file
4508 is silcd/packet_send.[ch].
4510 * The notify packets that are destined directly to the client used
4511 to not to be processed by the server. Now changed that and the
4512 server processes all notify packets. After relaying the packet
4513 to the client the notify packet is processed in the server.
4515 * The silc_server_free_client_data now checks whether there is
4516 pending outgoing traffic for the client and purges the data to
4517 the network before removing the client entry.
4519 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4521 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4522 an client is killed from the SILC Network. Updated the protocol
4525 Added new function silc_server_send_notify_killed to the
4526 silcd/packet_send.[ch].
4528 * Added function silc_server_packet_relay_notify to relay notify
4529 packets that are destined directly to a client. In this case
4530 the server does not process the notify packets but merely relays
4531 it to the client. Affected file silcd/packet_send.[ch].
4533 Added also silc_server_packet_process_relay_notify to check
4534 whereto relay the notify. Affected file is
4535 silcd/packet_receive.[ch].
4537 * Implemented the KILL command to the server.
4541 * Added the backup schema desgined last fall to the protocol
4542 specs for everyone to see. The specification is in the
4543 *-spec-xx.txt draft and the packet type definitions for the
4544 backup routers is in *-pp-xx.txt draft. Thusly, added also
4545 new packet type SILC_PACKET_CELL_ROUTERS.
4547 * A big security problem in the implementation discovered. The
4548 signoff of an client did not cause new channel key generation
4549 which it of course should've done. The channel keys must be
4550 always re-generated when client leaves (or signoffs) the channel.
4551 The silc_server_remove_from_channels funtion now handles
4552 the channel key re-generation.
4554 * Added `sender' argument to the silc_server_send_notify_on_channels
4555 to not to send the client provided as argument. Affected file
4556 silcd/packet_send.[ch].
4558 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Implemented OPER and SILCOPER commands into the server and
4563 * Added silc_auth_verify and silc_auth_verify_data to verify
4564 the authentication directly from the authentication payload.
4565 It supports verifying both passphrase and public key based
4566 authentication. Affected file lib/silccore/silcauth.[ch].
4568 * Added `hash' field to the SilcIDListData structure. It is the
4569 hash negotiated in the SKE protocol. Affected file is
4572 * Slight redesigning of the SilcAuthPayload handling routines.
4573 Do not send SilcPKCS but SilcPublicKey as argument.
4575 * Implemented the public key authentication support to the
4576 serverconfig. The public key is loaded from the provided path
4577 and saved as authentication data to void * pointer. Thus,
4578 changed the unsigned char *auth_data to void *auth_data;
4580 * Fixed SHUTDOWN command to send the reply before the server
4581 is shutdown. :) Affected file silcd/command.c.
4583 * Fixed fatal bug in CONNECT command. The hostname was invalid
4584 memory and server crashed. Affected file silcd/command.c.
4586 * Fixed fatal bug in CLOSE command. The server_entry became
4587 invalid but was referenced later in the command. Affected file
4590 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4592 * Fixed fatal bug in failure packet handling. Server ignored
4593 the failure and thus crashed when it came.
4597 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4599 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4600 that the command may be executed only once in (about) 2 seconds.
4601 The old SILC_CF_LAG flag is same but allows command bursts up
4602 to five before limiting.
4604 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4605 server code. Various commands now includes the CF_LAG_STRICT
4606 flag to disallow any kind of miss-use of the command.
4608 * Fixed the silc_buffer_unformat to not to allocate any data
4609 if the length of the data is zero. It used to allocate the
4610 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4612 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4614 * Changed the format of AdminConnection configuration section
4615 in the server. Added username of the admin to the format.
4616 Affected files silcd/serverconfig.[ch].
4618 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4619 to return admin configuration data by host, username and/or
4622 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4624 * Implemented WHOWAS command to the server. Added the functions:
4626 silc_server_command_whowas_parse,
4627 silc_server_command_whowas_send_reply,
4628 silc_server_command_whowas_from_client and
4629 silc_server_command_whowas_from_server
4631 * Added <Client ID> argument to the WHOWAS command reply. Updated
4632 the protocol specs accordingly.
4634 * Implemented WHOWAS command and command_reply to the client
4637 Implemented the WHOWAS printing on the user interface.
4639 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Added new argument to the WHOWAS command reply, the real name.
4642 It is an optional argument. Updated the protocol specs.
4644 * Added SilcIDCacheDestructor callback that is registered when
4645 the SilcIDCache is allocated. The callback is called when
4646 an cache entry in the ID Cache expires, or is purged from the
4647 cache. Added into lib/silccore/idcache.[ch].
4649 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4650 to destruct the client entries when the cache entry expires.
4651 Other ID Cache's in server and in the client library ignores
4654 * If the ID Cache entry's `expire' field is zero then the entry
4655 never expires. Added boolean `expire' argument to the
4656 silc_idcache_add function in the lib/silccore/idcache.[ch].
4657 If it is TRUE the default expiry value is used.
4659 * Added silc_server_free_client_data_timeout that is registered
4660 when client disconnects. By default for 5 minutes we preserve
4661 the client entry for history - for WHOWAS command.
4663 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4665 * Added support to the server to enforce that commands are not
4666 executed more than once in 2 seconds. If server receives
4667 commands from client more frequently, timeout is registered
4668 to process the commands. Affected file silcd/command.c.
4669 Added new function silc_server_command_process_timeout.
4671 * Changed NICK_NOTIFY handling in client library to check that
4672 if the client's nickname was changed, so there is no need to
4673 resolve anything from the server.
4675 * Removed error printing from the WHOIS and IDENTIFY commands.
4676 If error occurs then it is ignored silently in the client library.
4677 The application, however, may map the received error to
4678 human readable error string. The application currently maps
4679 the NO_SUCH_NICKNAME error to string.
4681 * Made the command status message public to the application. Moved
4682 them from lib/silcclient/command_reply.c to
4683 lib/silcclient/command_reply.h. The application can map the
4684 received command status to the string with the
4685 silc_client_command_status_message function.
4687 * Added check to the server to check that client's ID is same
4688 as the Source ID in the packet the client sent. They must
4691 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * Added dist-bzip hook to the Makefile.am to make bzip2
4694 compressed distributions.
4696 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4698 * Server now enforces the maximum length for the nickname and
4699 the channel as protocol specification dictates. 128 bytes for
4700 nickname and 256 bytes for channel name.
4702 * Moved the WHOIS printing to the application. The client libary
4703 does not print out the WHOIS information anymore, the application
4704 must do it. Renamed silc_client_command_reply_whois_print to
4705 the silc_client_command_reply_whois_save.
4707 The client's idle time is also sent to the application now, and
4708 the idle is shown on screen.
4710 * Added silc_client_command_reply_identify_save to save the
4711 received IDENTIFY entries.
4713 * Do not check for channel private keys in message sending and
4714 reception if the channel does not have the PRIVKEY mode set.
4715 Affected file lib/silclient/client_channel.c.
4717 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4720 just surfaced after chaning the JOIN procedure.
4722 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4724 * Added silc_client_get_clients_by_list to get client entries
4725 from Client ID list, that is returned for example by JOIN
4726 and USERS command replies. The application should use this
4727 function for example when JOIN command reply is received to
4728 resolve the clients already on the channel (library does not
4729 do that anymore as USERS command reply is not used in the JOIN
4730 procedure anymore). Affected files lib/silcclient/silcapi.h and
4731 lib/silcclient/idlist.c.
4733 * JOIN command reply and USERS command reply returns now SilcBuffer
4734 pointers instead of unsigned char pointers when returning
4735 the client list and mode list.
4737 * Added <Client ID> argument to the JOIN command reply, mainly
4738 for the server to identify for which client the command was
4739 originally sent. Updated protocol specs accordingly.
4741 * Added SilcDlist private_key pointer to the SilcChannelEntry
4742 in the client to support the channel private keys. Affected
4743 file is lib/silcclient/idlist.h.
4745 * Added SilcChannelPrivateKey argument to the function
4746 silc_client_send_channel_message so that application can choose
4747 to use specific private ke if it wants to. If it is not provided,
4748 the normal channel key is used, unless private keys are set.
4749 In this case the first (key that was added first) is used
4750 as the encryption key.
4752 * Implemented the support for channel private key handling.
4753 Implemented the following functions:
4755 silc_client_add_channel_private_key,
4756 silc_client_del_channel_private_keys,
4757 silc_client_del_channel_private_key,
4758 silc_client_list_channel_private_keys and
4759 silc_client_free_channel_private_keys
4761 Affected file lib/silcclient/client_channel.c.
4763 * Added the support for the private keys in the channel message
4764 sending and encryption and in the message reception and
4765 decryption. Affected funtions are
4766 silc_client_send_channel_message and silc_client_channel_message.
4768 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Added SKE's key verify callback to the client library's
4771 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4773 * Removed the statement that server (or router) must send USERS
4774 command reply when joining to the channel so that the client
4775 knows who are on the channel. Instead, the client list and
4776 client's mode list is now sent in the JOIN command reply to the
4777 client who joined channel. This is better solution.
4779 * Added function silc_server_get_users_on_channel and function
4780 silc_server_save_users_on_channel to the silcd/server.[ch].
4782 * Removed function silc_server_command_send_users from the
4785 * Do not show topic on the client library anymore. The topic is
4786 sent in the command reply notify to the application and the
4787 application must show the topic now.
4789 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4791 * Added client searching by nickname hash into the IDENTIFY and
4792 WHOIS commands in the server as they were clearly missing from
4793 them. Affected file is silcd/command.c.
4795 * Fixed a bug in private message receiving in the client library.
4796 The remote ID was freed and it wasn't supposed, now it is
4799 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4801 * Minor fix to the channel payload; allocate the data area, as it
4802 needs to be of specific length.
4804 * If the key agreement port is zero then the operating
4805 system will define the bound port. Affected files are
4806 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4808 * Added new function silc_channel_payload_decrypt into the file
4809 lib/silccore/silcchannel.[ch].
4811 * Moved the channel message etc, check from silc_packet_decrypt
4812 to applications. The library calls now a generic
4813 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4814 when the packet is either normal or special. This was done to
4815 allow more wide range of checking that was not allowed when
4816 the code was in library. Now applications can do virtually any
4817 checks to the packet and return to the library the decision how
4818 the packet should be processed. Affected files are
4819 lib/silccore/silcpacket.[ch].
4821 Added silc_server_packet_decrypt_check to the server and
4822 silc_client_packet_decrypt_check to the client library.
4824 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4825 to send with specified source and destination information.
4827 * Channel message delivery between routers was broken after the
4828 channel key distribution was fixed earlier. The channel key
4829 was used be to distributed to other routers as well which is not
4830 allowed by the protocol. Now this is fixed and channel keys
4831 really are cell specific and the channel message delivery between
4832 routers comply with the protocol specification.
4834 * Fixed various commands in server to check also the global list
4835 for the channel entry and not just the local list. The affected
4836 file silcd/command.c.
4838 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4840 * Added assert()s to buffer formatting and unformatting routines
4841 to assert (if --enable-debug) when error occurs. Affected
4842 file: lib/silcutil/silcbuffmt.c.
4844 * Changed to auto-reconnect to check whether the remote host is
4845 router and register the re-connect timeout if it is. It used
4846 to check that whether we are normal server, but router must do
4847 auto-reconnect with another router as well. Affected file
4850 * Removed the [<key len>] option from CMODE command as the cipher
4851 name decides the key length, nowadays. See the defined ciphers
4852 from the protocol specification.
4854 * Added [<hmac>] option to the CMODE command to define the HMAC
4855 for the channel. Added SILC_CMODE_HMAC channel mode.
4857 * Added [<hmac>] option for the JOIN command so that user can
4858 select which HMAC is used to compute the MACs of the channel
4861 * Added Hmac field to the Channel Message Payload. The integrity
4862 of plaintext channel messages are now protected by computing
4863 MAC of the message and attaching the MAC to the payload. The
4864 MAC is encrypted. Now, it is clear that this causes some
4865 overhead to the size of the packet but rationale for this is that
4866 now the receiver can verify whether the channel message decrypted
4867 correctly and also when private keys are set for the channel the
4868 receiver can decrypt the packet with several keys and check from
4869 the MAC which key decrypted the message correctly.
4871 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4872 lib/silccrypt/silccipher.[ch].
4874 * Added silc_hash_len to return the digest length into the
4875 lib/silcrypt/silchash.[ch].
4877 * Rewrote parts of Silc Channel Payload interface in the
4878 lib/silccore/silcchannel.[ch]. The encode function now also
4879 encrypts the packet and parse function decrypts it.
4881 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4883 * Fixed a minor formatting bug in the SKE's key material processing.
4884 It actually might have processed the keys wrong way resulting
4887 * Redefined the mandatory HMAC algorithms and added new algorithms.
4888 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4889 and hmac-md5 truncated to 96 bits. The mandatory is now
4890 hmac-sha1-96. Rest are optional (including the one that used
4891 to be mandatory). Rationale for this is that the truncated HMAC
4892 length is sufficient from security point of view and can actually
4893 make the attack against the HMAC harder. Also, the truncated
4894 HMAC causes less overhead to the packets. See the RFC2104 for
4897 * Added new [hmac] configuration section. The SKE used to use
4898 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4899 is of course wrong. The official names that must be proposed in
4900 the SKE are the ones defined in the protocol specification
4901 (hmac-sha1-96 for example). The user can configure any hmac
4902 using any hash function configured in the [hash] section. At
4903 least, the mandatory must be configured.
4905 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4907 * Added HMAC list to the SKE proposal list. It has now both
4908 hash algorithm list and HMAC list. This makes the protocol
4909 incompatible with previous versions. The SKE now seems to work
4910 the way it is supposed to work, for the first time actually.
4912 * Defined plain Hash algorithms to the protocol specification.
4915 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4917 * Implemented support for key agreement packets into the server.
4918 Added functions silc_server_key_agreement and
4919 silc_server_send_key_agreement. Other than these functions,
4920 server has nothing to do with this packet.
4922 * Added support for private message key packets into the server.
4923 Added functions silc_server_private_message_key and
4924 silc_server_send_private_message_key.
4928 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4929 called in the protocol's final callback instead in the END
4930 protocol state. This makes a little more sense and in the same
4931 time in client we can use the same protocol routines for normal
4932 key exchange and to key agreement packet handling as well.
4934 * Added to both client's and server's KE protocol context the
4935 SilcSKEKeyMaterial pointer to save the key material. We will
4936 bring the key material to the protocol's final callback by doing
4937 this. The final callback must free the key material.
4939 * Added SKE's packet_send callback into client's KE protocol
4940 context so that the caller can choose what packet sending function
4941 is used. This way we can use different packet sending when
4942 doing normal SKE when doing key agreement packet handling (in
4943 the key agreement packet handling we do not want to encrypt
4946 * Implemented the responder side of the key agreement routines
4947 in the client. The client can now bind to specified port and
4948 accept incoming key negotiation. The key material is passed
4949 to the application after the protocol is over.
4951 * Implemented the processing of incoming Key Agreement packet
4952 in the client. Added function silc_client_key_agreement to
4955 * Implemented the intiator side of the key agreement routines
4956 in the client. The client can now initiate key agreement with
4957 another remote client. The key material is passed to the
4958 application after the protocol is over.
4960 * Created client_keyagr.c to include all the key agreement
4963 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4964 SILC_TASK_CALLBACK except that it is not static.
4966 * Created client_notify.c and moved the Notify packet handling
4967 from the client.[ch] into that file.
4969 * Created client_prvmsg.c and moved all private message and
4970 private message key routines from the client.[ch] into that file.
4972 * Create client_channel.c and moved all channel message and
4973 channel private key routines from the client.[ch] into that file.
4975 * Changed silc_client_get_client_by_id_resolve to resolve with
4976 WHOIS command instead of IDENTIFY command, in the file
4977 lib/silclient/idlist.c.
4979 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4981 * Implemented the SKE's responder side to the Client library.
4983 * When FAILURE is received to the protocol do not trust it
4984 blindly. Register a timeout to wait whether the remote closes
4985 the connection as it should do it, only after that process the
4986 actual failure. This was changed to both client and server.
4988 * Added client_internal.h to include some of the structures
4989 there instead of client.h in lib/silcclient/.
4991 * Added function silc_task_unregister_by_callback to unregister
4992 timeouts by the callback function.
4994 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4996 * Some "Incomplete WHOIS info" errors has been appearing on the
4997 log files. Took away the entry->userinfo check from WHOIS
4998 reply sending. The entry->userinfo is now " " if client did not
4999 provide one. I thought this was fixed earlier but something
5000 is wrong still. Let's see if the error still appears.
5002 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5004 * Fixed a minor bug in the login when the channel key is
5005 re-generated in the server. It used to generate the key in
5006 wrong order and thus caused problems in the channel traffic.
5008 * Fixed a minor bug in channel key distsribution after
5009 KICK command. The key was not sent to the router even though
5012 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5014 * Added silc_ske_process_key_material_data as generic routine
5015 to process any key material as the SILC protocol dictates. The
5016 function is used by the actual SKE library but can be used by
5017 applications as well. This relates to the private message keys
5018 and the channel private keys since they must be processed the
5019 same way the normal SILC session keys. The protocol dictates
5020 this. Affected files: lib/silcske/silcske.[ch].
5022 Added also silc_ske_free_key_material to free the
5023 SilcSKEKeyMaterial structure.
5025 * Defined silc_cipher_set_key function to set the key for
5026 cipher without using the object's method function. The affected
5027 files: lib/silccrypt/silccipher.[ch].
5029 * Implemented silc silc_client_add_private_message_key,
5030 silc_client_add_private_message_key_ske,
5031 silc_client_del_private_message_key,
5032 silc_client_list_private_message_keys and
5033 silc_client_free_private_message_keys functions in the
5036 Added functions silc_client_send_private_message_key to send
5037 the Private Message Key payload and silc_client_private_message_key
5038 to handle incoming Private Message Key payload.
5040 * Added Cipher field to the Private Message Key payload to set
5041 the cipher to be used. If ignored, the default cipher defined
5042 in the SILC protocol (aes-256-cbc) is used.
5044 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Removed lib/silcclient/ops.h file.
5048 Redefined parts of the SILC Client Library API. Created new
5049 file silcapi.h that deprecates the ops.h file and defines the
5050 published Client Library API. Defined also private message key
5051 API and channel private key API into the file.
5053 This is the file that the application must include from the
5054 SILC Client Library. Other files need not be included by
5055 the application anymore.
5057 * Added new key_agreement client operation callback and also
5058 defined the Key Agreement library API for the application.
5060 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5063 is used by clients to request key negotiation between another
5064 client in the SILC network. If the negotiation is started it
5065 is performed using the SKE protocol. The result of the
5066 negotiation, the secret key material, can be used for example
5067 as private message key.
5069 Implemented the Key Agreement payload into the files
5070 lib/silccore/silauth.[ch].
5072 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5074 * Redefined ciphers for the SILC protocol. Added some new ciphers
5075 and defined the key lengths for the algorithms. Changed the
5076 code accordingly. The default key length is now 256 bits.
5078 * Fixed SKE key distribution function silc_ske_process_key_material
5079 when the key length is more than 128 bits. The default key
5080 length in SILC is now 256 bits.
5082 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5083 to indicate unsupported algorithm.
5085 * Renamed rijndael.c to aes.c and all functions as well.
5087 * Fixed a long standing channel key setting bug in client library.
5088 Weird that it has never surfaced before.
5090 * Fixed bug in channel deletion. If the entire channel is removed
5091 then it must also delete the references of the channel entry
5092 from the client's channel list as the client's channel entry and
5093 the channel's client entry share same memory.
5095 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5097 * Implemented CONNECT and SHUTDOWN commands in the client.
5099 * Implemented CLOSE command to the client.
5101 * Added the function silc_idlist_find_server_by_name into the
5102 files silcd/idlist.[ch].
5104 Added the function silc_idlist_find_server_by_conn into the
5105 files silcd/idlist.[ch].
5107 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * DIE command was renamed to SHUTDOWN. Updated the both code
5112 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5113 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5115 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5118 * Added function silc_server_create_connection function to create
5119 connection to remote router. My server implementation actually
5120 does not allow router to connect to normal server (it expects
5121 that normal server always initiates the connection to the router)
5122 so the CONNECT command is only good for connecting to another
5125 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5127 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5128 or some other client was kicked from the channel.
5130 Implemented the handling of the notify type to both client
5133 Implemented silc_server_send_notify_kicked to send the KICKED
5134 notify. It is used to send it to the server's primary router.
5136 * Implemented the KICK command into server and client.
5138 * Added `query' argument to the silc_idlist_get_client function
5139 to indicate whether to query the client from server or not if
5142 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5143 to indicate that the client is not channel founder.
5147 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5149 * Removed the rng context from SilcPacketContext structure and
5150 changed that the packet routine uses the Global RNG API.
5152 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5154 * Added support for quit message that client can "leave" on the
5155 channel when it quits the SILC. It is ditributed inside the
5156 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5158 Added silc_server_free_client_data that will take the
5159 signoff message as argument.
5161 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5163 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5165 * Updated parts of the protocol specification to keep it up
5168 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5170 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5171 payloads in one packet.
5173 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5174 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5175 use now the new List flag.
5177 * Also deprecated the following packet types: REPLACE_ID,
5178 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5180 * Added list support for Notify packet in server.
5182 * Added silc_server_send_notify_channel_change to send the
5183 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5184 the silc_server_send_replace_id.
5186 * Added silc_server_send_notify_nick_change to send the
5187 NICK_CHANGE notify type. Deprecates the function
5188 silc_server_send_replace_id.
5190 * Added silc_server_send_notify_join to send the JOIN notify type.
5191 Deprecates the function silc_server_send_new_channel_user.
5193 * Added silc_server_send_notify_leave to send LEAVE notify type.
5194 Deprecates the function silc_server_send_remove_channel_user.
5196 * Added silc_server_send_notify_cmode and
5197 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5198 types. Deprecates the silc_server_send_set_mode function.
5200 * Added SERVER_SIGNOFF notify type to indicate that server has
5201 quit. This means that all clients on the channel from that
5202 server will drop. This can be also used when netsplit happens.
5204 Deprecated REMOVE_ID packet type since it is not needed anymore
5207 Added silc_server_send_notify_server_signoff to send the
5208 SERVER_SIGNOFF notify type. Deprecates the function
5209 silc_server_send_remove_id.
5211 Added also silc_server_send_notify_signoff to send the
5212 SIGNOFF notify type.
5214 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5215 SILC protocol from this day on. Changed the protocol
5216 specification as well.
5218 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5219 notify type. It is used between routers to notify about
5220 topic changes on a channel.
5222 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5225 * Partly updated the protocol specification to comply with the
5226 changes now made. It is still though a bit outdated.
5228 * The JOIN notify type now takes one extra argument <Channel ID>.
5229 The packet used to be destined to the channel but now the
5230 JOIN type may be sent as list thus it is impossible to
5231 destine it to any specific channel. By adding this argument
5232 it is again possible.
5234 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5236 * Added CREDITS file. The CHANGES and CREDITS file will appear
5237 in the distribution as well.
5239 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5241 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5242 types in the server's silcd/packet_receive.c.
5244 * Implemented CMODE and CUMODE to work in router environment.
5246 * Fixed minor encoding and decoding buglet from the
5247 lib/silccore/silcmode.c.
5249 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5252 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5254 * Changed all SilcConfigServer* and silc_config_server* to
5255 SilcServerConfig* and silc_server_config*, respectively.
5258 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5260 * Associated the ID (client or server ID) to the Authentication
5261 Payload to avoid any possibility of forging. Updated the
5262 protocol specification and the code accordingly.
5264 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5266 * The RSA key length is now save to the RsaKey context in the
5267 key generation process in lib/silccrypt/rsa.c. The key length
5268 is now used to figure out the maximum size of the block allowed
5269 to be encrypted/signed.
5271 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5272 is equivalent to the silc_mp_mp2bin but does not allocate any
5275 * Changed silc_mp_mp2bin API to take length argument. If it is
5276 non-zero then the buffer is allocated that large. If zero, then
5277 the size is approximated using silc_mp_sizeinbase, which however
5280 * Created Global RNG API which is global RNG that application can
5281 initialize. After initializing, any routine anywhere in the
5282 code (including library) can use RNG without allocating a new
5283 RNG object. This was done to allow this sort of use of the
5284 RNG in code that has no chance to allocate RNG object. All
5285 applications currently allocate this and many routines in the
5286 library use this. Affected file lib/silccrypt/silcrng.[ch].
5288 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5289 it to use the Global RNG API.
5291 * Defined Authentication Payload into protocol specification that
5292 is used during SILC session to authenticate entities. It is
5293 used for example by client to authenticate itself to the server
5294 to obtain server operator privileges.
5296 Implemented this payload into the lib/silccore/silcauth.[ch].
5297 Implemented also routines for public key based authentication
5298 as the new protocol specification dictates.
5300 Moved definitions of different authentication methods from
5301 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5303 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5304 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5305 silc_pkcs_verify_with_hash functions into the file
5306 lib/silccrypt/silcpkcs.[ch].
5308 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5310 * The client entry's userinfo pointer must be always valid.
5311 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5312 will fail since it requires the userinfo. Now, the userinfo
5313 is allocated as "" if actual userinfo does not exist. Actually,
5314 it must exist and it is totally Ok to drop client connections
5315 that does not announce the userinfo. However, we will make
5316 this workaround for now.
5318 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5319 to return the remote port by socket.
5321 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5323 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5324 SILC_SERVER_PENDING_EXEC and added an new macro
5325 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5326 data or when error occurs while processing the pending command.
5328 Added new argument `destructor' into silc_server_command_pending
5329 and to the SilcServerCommandPending object. This destructor is
5330 now called after calling the pending callback or if error occurs
5331 immediately. If error occurs the actual pending callback won't
5332 be called at all - only the destructor. The destructor may be
5333 NULL if destructor is not needed.
5335 All this applies for client library code as well. Similar
5336 changes were made there as well for the pending commands.
5338 In the client, the application must now allocate the
5339 SilcClientCommandContext with the silc_client_command_alloc
5342 * Added reference counter to the SilcServerCommandContext. Added
5343 function silc_server_command_alloc and silc_server_command_dup
5346 Same type of functions added to the client library for the same
5349 * Removed the cmd_ident from IDListData away since it is now
5350 global for all connections. It is the command identifier used
5351 in command sending and with pending commands. The affected file
5354 * Added reference counter to the SilcSocketConnection objecet to
5355 indicate the usage count of the object. The object won't be
5356 freed untill the reference counter hits zero. Currently only
5357 server uses this, and client ignores it. The client must be
5358 set to use this too later. The affected files are
5359 lib/silccore/silcsockconn.[ch]. Added also the function
5360 silc_socket_dup to increase the reference counter.
5362 This was mainly added because it is possible that the socket
5363 is removed underneath of pending command or other async
5364 operation. Now it won't be free'd and proper DISCONNECTING
5365 flags, etc. can be set to avoid sending data to connection that
5366 is not valid anymore.
5368 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5369 the connection. After that it sets SILC_SET_DISCONNECTED.
5370 It is, however, possible that the socket data is not still freed.
5371 The silc_server_packet_process now checks that data is not
5372 read or written to connection that is DISCONNECTED. The socket
5373 get's freed when the reference counter hits zero.
5375 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5377 * Changed the client operation API: channel_message operation's
5378 `sender' is now the client entry of the sender, not the nickname
5379 and the `channel' is the channel entry, not the channel name.
5381 In the private_message operation the `sender' is now also the
5382 client entry of the sender not the nickname.
5384 Affected file is lib/silcclient/ops.h and all applications
5385 using the client operations.
5387 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5389 * Moved the calling of ops->connect() from connect_to_server_final
5390 into receive_new_id functin since that is the point when the
5391 client is actually allowed to send traffic to network. The
5392 affected file is lib/silcclient/client.c.
5394 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5397 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5398 (if needs broadcasting) instead of broadcasting the packets one
5399 by one which would make a burst in the network traffic.
5401 * Added `broadcast' argument to the functions in silcd/server.[ch]
5402 silc_server_create_new_channel[_with_id] to indicate whether
5403 to send New Channel packet to primary router.
5405 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Added new function into the silcd/server.[ch] files:
5408 silc_server_create_new_channel_with_id to create new channel with
5409 already existing Channel ID.
5411 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5412 lib/silccore/silcpacket.h. This packet is used t send list of
5413 Set Mode payloads inside one packet. Server uses this to set
5414 the modes for the channels and clients on those channels, that it
5415 announced to the router when it connected to it. The protocol
5416 specification has been updated accordingly.
5418 * The silc_server_new_channel did not handle the packet coming
5419 from normal server as it normally does not send that. However,
5420 when it announces its channels it does send it. Implemented
5421 the support for that.
5423 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5424 into the file lib/silccore/id.h.
5426 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * Fixed memory leaks in the functions silc_idlist_del_client,
5429 silc_idlist_del_channel and silc_idlist_del_server in the file
5430 silcd/idlist.c. All of those leaked like a sieve.
5432 * Fixed some small memory leaks in the client's function
5433 silc_client_notify_by_server.
5435 * Added functions into silcd/server.c: silc_server_announce_clients,
5436 silc_server_announce_channels and silc_server_announce_server.
5437 These functions are used by normal and router server to announce
5438 to its primary router about clients, channels and servers (when
5439 router) that we own. This is done after we've connected to the
5442 These functions effectively implements the following packet types:
5443 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5444 and SILC_PACKET_NEW_ID_LIST.
5446 * Added new functions into the silcd/packet_receive.[ch]:
5447 silc_server_new_id_list, silc_server_new_channel_list and
5448 silc_server_new_channel_user_list to handle the incoming
5449 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5451 * Added support of changing Channel ID in the function
5452 silc_server_replace_id. If the server that announces a channel
5453 to the router already exists in the router (with same name but
5454 with different Channel ID), router is responsible to send
5455 Replace ID packet to the server and force the server to change
5456 the Channel ID to the one router has.
5458 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5459 client that the Channel ID has been changed by the router. The
5460 normal server sends this to the client. Client must start using
5461 the new Channel ID as the channel's ID.
5463 Implemented handling of this new type into lib/silcclient/client.c
5464 into the function silc_client_notify_by_server.
5466 * Added new function silc_idlist_replace_channel_id into the files
5467 silcd/idlist.[ch] to replace the Channel ID.
5469 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5471 * Call silc_server_command_identify_check always when processing
5472 the IDENTIFY command in silcd/command.c
5474 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5476 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5477 send keepalive packets. The packet can be sent by clients,
5478 servers and routers.
5480 Added function silc_socket_set_heartbeat into the file
5481 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5482 If not set, the heartbeat is not performed. The actual
5483 heartbeat is implemented in the low level socket connection
5484 library. However, application is responsible of actually
5487 Added silc_server_send_heartbeat to send the actual heartbeat
5488 packet into silcd/packet_send.[ch]. Server now performs
5489 keepalive with all connections.
5491 * Added silc_task_get_first function into lib/silcutil/silctask.c
5492 to return the timeout task with shortest timeout. There was a bug
5493 in task unregistration that caused problems. TODO has been
5494 updated to include that task system must be rewritten.
5496 * The client library will now resolve the client information when
5497 receiving JOIN notify from server for client that we know but
5498 have incomplete information.
5500 * Rewrote parts of silc_server_remove_from_channels and
5501 silc_server_remove_from_one_channel as they did not remove the
5502 channel in some circumstances even though they should've.
5504 * Encryption problem encountered in server:
5506 The LEAVE command used to send the Channel Key packet to the
5507 router immediately after generating it. However, the code
5508 had earlier sent Remove Channel user packet but not immediately,
5509 ie. it was put to queue. The order of packets in the router
5510 was that Channel Key packet was first and Remove Channel User
5511 packet was second, even though they were encrypted in the
5512 reverse order. For this reason, MAC check failed. Now, this
5513 is fixed by not sending the Channel Key packet immediately but
5514 putting it to queue. However, this is more fundamental problem:
5515 packets that are in queue should actually not be encrypted
5516 because packets that are sent immediately gets encrypted
5517 actually with wrong IV (and thus MAC check fails). So, packets
5518 that are in queue should be encrypted when they are sent to
5519 the wire and not when they put to the queue.
5521 However, the problem is that the current system has not been
5522 designed to work that way. Instead, the packet is encrypted
5523 as soon as possible and left to the queue. The queue is then
5524 just purged into wire. There won't be any fixes for this
5525 any time soon. So, the current semantic for packet sending
5528 o If you send packet to remote host and do not force the send
5529 (the packet will be in queue) then all subsequent packets to the
5530 same remote host must also be put to the queue. Only after the
5531 queue has been purged is it safe again to force the packet
5534 o If you send all packets immediately then it safe to send
5535 any of subsequent packets through the queue, however, after
5536 the first packet is put to queue then any subsequent packets
5537 must also be put to the queue.
5539 Follow these rules and everything works fine.
5541 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5543 * Added new function silc_server_remove_clients_by_server to
5544 remove all client entries from ID list when the server connection
5545 is lost. In this case it is also important to invalidate all
5546 client entires as they hold the invalid server entry. This
5547 fixes fatal bug when server has lost connection and will reconnect
5550 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5552 * Made some sanity checks to silc_server_daemonise like to check
5553 whether the requested user and group actually exists.
5555 * Added sanity check to SKE's silc_ske_responder_finish to check
5556 that the public and private key actually is valid.
5558 * Invalidate the client's nickname when receiving Replace ID
5559 packet and the Client ID is being replaced. This means that the
5560 server will query the nickname if someone needs it (client)
5563 * Sort the ID Cache in client library when the ID Cache data
5564 has changed (needs sorting).
5566 * Do not allow for SILC client to create several connections to
5567 several servers. The client does not support windows right now
5568 and generating multiple connections causes weird behaviour.
5570 Irssi-silc client does support windows and can handle several
5571 connections without problems, see: www.irssi.org and SILC plugin.
5573 * Fixed some places where client was added to the IDList. The
5574 rule of thumb is following (in order to get everything right):
5575 If the client is directly connected local client then the
5576 `connection' argument must be set and `router' argument must be
5577 NULL to silc_idlist_add_client function. If the client is not
5578 directly connected client then the `router' argument must
5579 bet set and the `connection' argument must be NULL to the
5580 silc_idlist_add_client function.
5582 * The funtion silc_server_packet_send_local_channel actually did
5583 not check whether the client was locally connected or not. It
5584 does that now. Fixed a bug related to LEAVE command.
5586 * Fixed Remove Channel User payload parsing bug in server's
5587 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5589 * The server's silc_server_save_channel_key now checks also the
5590 global ID list for the channel as it might not be in the local
5591 list. Fixed a bug related to LEAVE command.
5593 * Is this the end of the [<unknown>] buglet that has been lurking
5594 around for a long time? A little for loop fix in server's
5595 silc_server_command_whois_parse that is used by both IDENTIFY
5596 and WHOIS command. At least, this was a clear bug and a cause
5597 of one type of [<unknown>] buglet.
5599 * WHOIS and IDENTIFY commands call the function
5600 silc_server_command_[whois/identify]_check function even if
5601 we are not router server.
5603 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5605 * Added --with-gmp configuration option. If set the GMP
5606 is always compiled in the SILC source tree. If not set then
5607 it is checked whether the system has the GMP3 installed. If
5608 it has then the GMP won't be compiled (the system's headers
5609 and library is used), if it doesn't have it then the GMP is
5610 compiled in the SILC source tree.
5612 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5614 * Changed RSA private exponent generation to what PKCS #1
5615 suggests. We try to find the smallest possible d by doing
5616 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5617 not security fix but optimization.
5619 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5621 * Added new config entry [Identity] to fork the server and run
5622 it as specific user and group. A patch from Bostik.
5624 * Imported Dotconf configuration library into lib/dotconf.
5625 This will be used to create the SILC configuration files later.
5626 It will appear in the distsribution after this commit.
5628 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5630 * A big code auditing weekend happening. Auditing code for
5631 obvious mistakes, bugs and errors. Also, removing any code
5634 Removed files for being obsolete:
5636 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5637 inline in the file lib/silcutil/silcbuffer.h)
5639 o lib/silcutil/silcbufutil.c (the header has inline versions)
5641 Changed code to fix possible error conditions:
5643 o The buffer formatting routines now check that the destination
5644 buffer really has enough space to add the data. This applies for
5645 both buffer formatting and unformatting
5646 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5647 unformatting was changed to accomodate following rules:
5648 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5649 sent to the function while XXX_*STRING will not allocate or copy
5650 the data into the buffer. Instead it sets the pointer from the
5651 buffer into the pointer sent as argument (XXX_*STRING used to
5652 require that the pointer must be allocated already). This change
5653 makes this whole thing a bit more consistent and more optimized
5654 (note that the data returned in the unformatting with XXX_*STRING
5655 must not be freed now). The routines return now -1 on error.
5657 o Tried to find all code that use buffer_format and buffer_unformat
5658 and added return value checking to prevent formatting and
5659 especially unformatting errors and possible subsequent fatal
5662 o Changed ske->x and ske->KEY to mallocated pointers in
5663 lib/silcske/silcske.h. Fixed possible data and memory leak.
5665 o Added return value checking to all *_parse* functions. Fixed
5666 many memory leaks as well.
5668 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5669 so that buffer overflows would not happen. All code now also
5670 checks the return value as it can fail.
5672 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5674 * Added reconnection support to server if the normal server looses
5675 its connection to the router (for example if router is rebooted).
5676 The server performs normal reconnection strategy implemented
5677 to the server. Affected file silcd/server.c.
5679 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5681 * Added new packet type SILC_PACKET_SET_MODE that is used to
5682 distribute the information about changed modes (for clients,
5683 channels and clients channel modes) to all routers in the
5684 network. Updated the protocol specification accordingly.
5686 Added functions into silcd/packet_send.c and
5687 silcd/packet_receive.c: silc_server_send_set_mode,
5688 silc_server_set_mode.
5690 Added new files silcmode.[ch] into lib/silccore that implements
5691 the encoding and decoding of Set Mode Payload. Added new type
5692 SilcSetModePayload. Moved the definitions of different modes
5693 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5695 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5697 * Oops, a little mistake in server's connection authentication
5698 protocol. The protocol is not ended with FAILURE but with
5699 SUCCESS if the authentication is Ok. :) Affected file is
5702 * Implemented NICK_CHANGE notify handling in server in the file
5703 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5704 the local clients on the channel. After the changing nickname
5705 in router environment snhould work and the [<unknown>] nickname
5706 should appear no more.
5708 The silc_server_replace_id function that receives the Replace ID
5709 payload now sends the NICK_CHANGE notify type also in the file
5710 silcd/packet_receive.c
5712 * Changed WHOIS and IDENTIFY command to support the maximum amount
5713 of arguments defined in protocol specs (3328 arguments). This
5714 fixed a bug that caused problems when there were more than three
5717 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5719 * Added extra parameter, command identifier, to the
5720 silc_client_send_command so that explicit command identifier
5723 Changed that ID list routines uses specific command identifier
5724 when sending WHOIS/IDENTIFY requests to the server so that they
5725 can be identified when the reply comes back.
5727 Affected files lib/silcclient/command.[ch],
5728 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5730 * Added `sender' argument to silc_server_packet_send_to_channel
5731 to indicaet the sender who originally sent the packet to us
5732 that we are now re-sending. Ignored if NULL. Affected file
5733 silcd/packet_send.[ch].
5735 * Added some server statistics support in silcd/server_internal.h
5736 SilcServerStatistics structure and around the server code. Also
5737 send some nice statistics information when client is connecting
5740 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5742 * Fixed channel ID decoding in server's JOIN command reply in
5743 silcd/command_reply.c
5745 * Fixed braodcasting of replace ID payload to not to send it if
5746 we are standalone server in silcd/packet_receive.c.
5748 * Fixed all channel message sending routines to not to send
5749 packets to clients that has router set, since they are routed
5750 separately in the same function earlier. Affects file
5751 silcd/packet_send.c and all channel packet sending functions.
5753 * In USERS reply, res_argv[i] are not allocated, the table
5754 is allocated. Thus changed that free the table, not its
5757 * In server's whois_check and identify_check if the client is
5758 locally connected do not send any WHOIS commands - they are not
5761 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5763 * Fixed some minor bugs in client when sending WHOIS command. The
5764 arguments was in wrong order.
5766 * Removed statis function add_to_channel from server in
5767 silcd/command.c that was previously used with the joining but
5770 * Tested USERS command in router environment successfully with two
5771 routers, two servers and two clients.
5773 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5775 * Reorganized the USERS command and command reply in client library
5776 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5777 When the command is given by user we register a pending command
5778 callback that will reprocess the command after the reply has been
5779 received from the server. When reprocessing the packet we then
5780 display the information. Thus, the USERS information is displayed
5781 now in the command callback instead of in the command reply
5782 callback. The processing of the command is same as previously
5783 when server has sent the command reply in the JOINing process.
5785 * Added to USERS command in silcd/command_reply.c to join the client,
5786 we didn't use to know about, to the channel after we've created
5787 a client entry for it. Also, for clienet we did know already still
5788 check whether it is on the channel or not and add it if not.
5790 * Removed silc_server_command_join_notify as the function and its
5793 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5795 * Changed the client's pending command handling to the same as the
5796 server's pending command handling. It is also now possible to
5797 execute command reply functions from other command reply
5798 function as the function callbacks for commands and command
5799 replies are one and same. The pending commands are not static
5800 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5801 in client connection context. Thus, pending commands are server
5802 connection specific as it is convenient.
5804 Changed the function silc_client_command_pending and
5805 silc_client_command_pending_del and added new function
5806 silc_client_command_pending_check. Removed the
5807 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5810 * Added cmd_ident, current command identifier, to the client
5811 connection context in lib/silcclient/client.h to keep track on
5812 command identifiers used in command sending. Client's command reply
5813 function handling now supports the mandatory command identifiers.
5815 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5816 funtions in client to fully support pending command callbacks.
5818 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5819 as one of the arguments to the application in the command reply
5822 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5823 before first releasing SILC but came back. Now it is removed again
5824 and should come back nomore. The FORWARDED flag was used only
5825 by the JOINing procedure by forwarding the command packet to router.
5826 Now, the JOINing procedure has been changed to more generic (due
5827 to various router environment issues) and FORWARDED is not needed
5828 anymore for anything. The protocol specification is yet to be
5831 Now, removed silc_server_packet_forward from server and the flag
5832 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5834 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5836 * Renamed NAMES command to USERS command. The NAMES was named that
5837 due to historical reasons. Now it is renamed. Also, rewrote
5838 parts of the USERS command. The nickname list is not sent anymore
5839 by the server. Only Client ID and mode lists are sent in the USERS
5840 command. Changed this also to the protocol specification.
5842 The client now resolves the names and stuff after it receives
5843 the USERS list from the server when joining to the channel.
5845 * WHOIS and IDENTIFY commands has been changed to support multiple
5846 Client ID's per command. One can now search for multiple users
5847 in the network by sending only one WHOIS or IDENTIFY command.
5848 Changed the code and the protocol specifications.
5850 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5851 uses silc_server_command_whois_parse to parse the request. */
5853 * If normal server, do not parse the WHOIS and IDENTIFY requests
5854 before sending it to the router. Saves some time.
5856 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * Fixed JOIN command on client library. Wrong number of arguments
5859 used to crash the client.
5861 * Added silc_server_channel_has_global function to check whether
5862 channel has global users or not.
5864 * Added silc_server_channel_has_local function to check whether channel
5865 has locally connected clients on the channel.
5867 * The silc_server_remove_from_one_channel now checks whether the
5868 channel has global users or not after given client was removed from
5869 the channel. It also checks whether the channel has local clients
5870 on the channel anymore. If it does not have then the channel entry
5871 is removed as it is not needed anymore.
5873 * The silc_server_notify now checks on JOIN notify whether the joining
5874 client is one of locally connected or global. If it is global then
5875 the channel has now global users on the channel and that is marked
5876 to the channel entry. Also, it now saves the global client to
5877 global list who is joining and JOINs it to the channel. This is
5878 for normal server, that is.
5880 Changed silc_server_send_notify_on_channel,
5881 silc_server_packet_relay_to_channel and
5882 silc_server_packet_send_to_channel check if we are normal server
5883 and client has router set (ie. global client) do not send the
5884 message to that client, as it is already routed to our router.
5886 * Implemented LEAVE notify type handling in silc_server_notify
5889 * Tested LEAVE command in router environment successfully. Tested
5890 with two routers, two servers and two clients.
5894 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5896 * Implemented SIGNOFF notify type handling in silc_server_notify
5899 * silc_server_remove_id now removes the client entry from all channels
5900 it has joined and thusly sends SIGNOFF notify type.
5902 * Rewrote the NAMES list generation in server by removing two excess
5903 loops. The lists are created now inside one loop.
5905 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5907 * silc_server_remove_channel_user checks now also global list
5908 for channel and client.
5910 * silc_server_new_channel_user checks now both local and global
5911 list for channel and client. Fixed a bug in client id decoding.
5912 Used to decode wrong buffer.
5914 * silc_server_channel_message checks now both local and global
5915 list for channel entry.
5917 * Tested channel joining (hence JOIN) in router environment
5918 successfully. Tested with two routers, two servers and two
5921 * Tested channel message sending in router environment successfully.
5923 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5925 * Added silc_server_save_channel_key into server.[ch] to save the
5926 received channel key in Channel Key payload processing. It is
5927 also used in JOIN command reply handling.
5929 Equivalent function silc_client_save_channel_key added into
5930 client.[ch] into client library.
5932 * Changed JOIN command reply to send information whether the channel
5933 was created or not (is existing already) and the channel key
5934 payload. Changed protocol specs accordingly.
5936 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5937 the request was sent by ID and not by nickname. Crashed on
5940 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5942 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5943 now correctly save the received data.
5945 * silc_server_free_sock_user_data now notifies routers in the
5946 network about entities leaving the network.
5948 At the same time implemented functions silc_server_remove_id
5949 and silc_server_send_remove_id to receive and send REMOVE_ID
5950 packets. The packet is used to notify routers in the network
5951 about leaving entities. The ID removed will become invalid in
5954 * Added function silc_idlist_del_server into server. Removes and
5955 free's server entry from ID list.
5957 * silc_server_private_message function now checks, if we are router,
5958 that the destination ID really is valid ID, naturally.
5960 * In router when NEW_ID packet is received (for new client) the
5961 hash of the Client ID is saved in the ID Cache but the
5962 client->nickname is set to NULL, instead of putting the hash
5965 IDENTIFY command now also checks that client->nickname must be
5966 valid. If it is not if will request the data from the server who
5967 owns the client. Added new function
5968 silc_server_command_identify_check.
5970 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5971 to set the command to already allocated Command Payload.
5973 * Tested private message sending in router environment with two
5974 routers, two servers and two clients. Fixed minor bugs and now
5977 * Fixed segfault from client's NAMES command. Used to crash if
5980 * Forwarded packets must not be routed even if it is not destined
5981 to the receiver. Changed server code comply with this.
5983 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * Added `require_reverse_mapping' boolean value to ServerParams
5986 structure. If TRUE (not default) the server will require that
5987 the connecting host has fully qualified domain name.
5989 If the reverse mapping is not required and hostname could not be
5990 found the IP address is used as hostname.
5992 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5994 * Implemented version string checking to both client and server.
5995 The check is incomplete currently due to the abnormal version
5996 strings used in development version of SILC.
5998 * Changed all command functions in server to use the new
6001 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6003 * Changed char *data to unsigned char *data in ID Cache system to
6004 support binary data as ID Cache data. Changed code to support
6005 binary data in lib/silccore/idcache.c.
6007 * Renamed silc_server_packet_relay_command_reply to
6008 silc_server_command_reply as it is normal packet receiving
6009 function. Rewrote the function to accept command replys for
6010 servers and not only for clients.
6012 * Mark remote router always as registered server if we are connecting
6013 to it. Otherwise, commands sent by the router to us are ignored.
6015 * All ID List find routines now returns the ID Cache Entry pointer
6016 as well if requested.
6018 * WHOIS command works now in router environment, tested with two
6019 routers, two servers and two clients.
6021 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6022 in router environment (as it is almost equivalent to WHOIS) but
6023 hasn't been tested thoroughly. Added new functions:
6025 silc_server_command_identify_parse
6026 silc_server_command_identify_send_reply
6027 silc_server_command_identify_from_client
6028 silc_server_command_identify_from_server
6030 * Disabled route cache adding because adding two different ID's with
6031 same IP replaces the old cache entry thus giving wrong route.
6032 The entry->router->connection is always the fastest route anyway
6033 so route cache may not be needed. Of course, new routes maybe
6034 established after receiving the ID when the entry->router->connection
6035 might not be anymore the most optimal.
6037 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6039 * Add route cache for received ID for fast routing.
6041 * Added silc_server_packet_route to route received packet on router
6042 that is not destined to us.
6044 * Renamed silc_server_get_route to silc_server_route_get.
6046 * Added id_string and id_string_len fields into SilcServer to
6047 include encoded ServerID for fast comparing without excess
6048 encoding of the ID's.
6050 * Cleaned up WHOIS command on server side. Added following static
6053 silc_server_command_whois_parse
6054 silc_server_command_whois_check
6055 silc_server_command_whois_send_reply
6056 silc_server_command_whois_from_client
6057 silc_server_command_whois_from_server
6059 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6060 arguments in command replies. All command functions should be
6061 updated to use this macro.
6063 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6065 * Minor typo fixes on command reply handling on server.
6067 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6069 * Added silc_server_command_add_to_channel internal routine to add
6070 the client to the channel after router has created the channel and
6071 sent command reply to the server.
6073 * Added generic silc_server_send_command to send any command from
6076 * Use static buffer with ID rendering instead of duplicating data.
6078 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6080 * Fixed a channel user mode bug when joining to a channel server gave
6081 everybody channel founder rights, oops.
6083 * We mark ourselves as the router of the incoming server connection
6084 if we are router ourselves. This way we can check in some packet
6085 sending functions whether it is locally connected server. For
6086 incoming router connections we put NULL.
6088 * For router sending packets locally means now always sending the
6089 packet cell wide; to local clients and local servers. For normal
6090 server sending packet locally means sending it to only local
6093 * Fixed the JOIN command to really work in router environment. If the
6094 channel is created it is always created by the router. Router is
6095 also responsible of making the initial joining to the channel,
6096 sending JOIN notify to the sending server and distributing
6097 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6098 does not exist server doesn't do anything else but forward the
6099 command to the router which performs everything.
6101 * Added silc_server_send_channel_key function to send the Channel Key
6104 * Added silc_server_create_channel_key to create new channel key. The
6105 channel key is now re-generated everytime someone joins or leaves
6106 a channel, as protocol dictates. Note: channel->key_len is the
6109 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6111 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6112 packet_receive.[ch] to separate packet sending and receiving
6113 routines. The server.[ch] now includes everything else including
6114 actual packet processing (writing and reading data) and other
6117 Renamed silc_server_private_message_send_internal to
6118 silc_server_send_private_message. The routine is still though
6119 used only to relay private messages as server does not send
6120 private messages itself.
6122 Renamed silc_server_new_channel to silc_server_create_new_channel
6123 and added new function sicl_server_new_channel that handles the
6124 incoming New Channel packet. Added also new sending function
6125 silc_server_send_new_channel to send New Channel Payload.
6127 * Added new function silc_server_notify to process incoming notify
6128 packet to the server/router. Server may then relay the notify
6129 to clients if needed.
6131 * Added new function silc_server_new_channel_user to process incoming
6132 New Channel User packet. Router will redistribute the packet and
6133 send JOIN notify to its local clients and locally connected servers
6134 if needed. Normal server will send JOIN notify to its local client
6135 on same channel when received this packet. Added also corresponding
6136 sending function silc_server_send_new_channel_user to sent the
6139 * Added boolean route argument to send_notif_to_channel and
6140 packet_send_to_channel functions to attempt to route the packet
6141 if it is TRUE and send only locally if it is FALSE.
6143 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6145 * silc_server_replace_id now broadcasts the received replace ID
6146 packet if it is not broadcast packet already. The router must
6147 broadcast to inform other routers about changed ID.
6149 * Added backpointer to server's router into SilcServer context in
6150 silcd/server_internal.h.
6152 * Fixed silc_server_packet_broadcast to send correct broadcast
6155 * The channel key is now distributed to the local client as soon
6156 as it is received from the router (in router environment) so that
6157 no other packet may be sent for the channel until client has
6160 * silc_server_remove_channel_user now broadcasts the received
6161 Remove Channel User packet if it is not broadcast packet already.
6162 The router must broadcast to inform other routers about removed
6165 * Added users field into SilcPacketContext that is a reference count
6166 of the context. One can increase the reference count by calling
6167 silc_packet_context_dup which is now changed to just increase the
6168 reference count instead of duplicating the data. The reference
6169 count is decresed by calling silc_packet_context_free that will
6170 free the data after the reference count hits zero.
6172 For now on the packet context and everything allocated into it
6173 (including the raw packet from network) must be freed by calling
6174 the new silc_packet_context_free function. Added also new function
6175 silc_packet_context_alloc that must be used now to allocate the
6176 context. This also means that if a routine is asynchronous from
6177 silc_[client/server]_packet_parse_type the packet context must
6178 be duplicated by calling silc_packet_context_dup. Otherwise it
6179 gets free'd after silc_[client/server]_packet_parse_type returns.
6180 Also, one must remember that if packet is duplicated then its
6181 reference count must be decresed by calling the free function as
6182 many times as it was duplicated.
6184 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6185 from both client and server.
6187 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6189 * Made joining to a channel working in router environment.
6191 * Cleaned up JOIN command on server side and create function
6192 silc_server_command_join_channel internal routine to make the
6195 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6197 * Changed silc_command_pending list to SilcDList. Also, added
6198 `ident' field to SilcServerCommandPending structure to identify
6199 the reply and to call correct callback.
6201 Added silc_server_command_pending_check function to replace the
6202 corresnponding macro. The silc_command_pending list is not
6205 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6206 to set identifier to previously allocated Command Payload. It
6207 is used to set identifier for command when resending Command
6210 * Added silc_command_payload_encode_payload to encode Command
6211 Payload buffer from SilcCommandPayload structure.
6213 * Added silc_argument_payload_encode_payload to encode Argument
6214 payload buffer from SilcArgumentPayload structure.
6216 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6218 * Changed WHOIS command to support router connection on server side.
6219 The whois request is always sent to router unless the server is
6220 standalone server. After server has received the reply from the
6221 router will it send the reply to the client.
6223 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6224 broadcast received broadcast packet. The function is used only
6225 by router. The broadcast packet is always sent to the router's
6228 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6229 render given ID to printable string, for log files for example.
6231 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6233 * Made basic router to router connections working. At least they
6234 can now connect to each other but nothing really works the way
6235 they are supposed - yet.
6237 * Added new initiator token to RouterConnection configuration
6238 file in silcd/serverconfig.[ch]. It is used to tell whether we
6239 are the initiator to the remote router or whether we'll expect
6240 the other end to connect.
6242 * Moved registering of listener task to silc_server_init, hence
6243 the server starts listenning as soon as it is run, even if it
6244 does not have connections to other routers. Let's see how well
6247 * Changed default connection retry timeouts for more suitable in
6250 * Removed cipher and such arguments from silc_idlist_add_client
6251 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6252 Added new function silc_idlist_add_data to add the keys and stuff
6255 * Added SilcIDListData structure and added it to SilcClientEntry
6256 and SilcServerEntry as their first field in the structure. This
6257 way we can explicitly cast the ID entries to the SilcIDListData
6258 structure and get common data for the entries. In past, we had
6259 to first check what type of connection it is and then cast it to
6260 correct ID entry type. Now, we can directly cast the opaque
6261 pointer to the SilcIDListData (no matter what ID entry it actually
6262 is) and get the data needed.
6264 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6266 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6267 in some circumstances even if threre were timeout tasks, though not
6268 IO tasks, but tasks anyway. Now fixed.
6270 * Defined SilcServerConnection structure to hold connection specific
6271 stuff about directly connected servers and routers. The definition
6272 is currently in silcd/server_internal.h. I thought about having
6273 a bit more important role fro this struct but for now it is used
6274 only when connecting to other server (or router actually).
6276 * Added connecting retry support in server when connecting to
6277 router(s). The retry feature implement exponential backoff
6278 algorithm. Also, added SilcServerParams structure to hold default
6279 parameters for server. For now, it include these retry settings
6280 and are hard coded. After server is moded to be as Silc Server
6281 Library this structure will be more important.
6283 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6285 * Changed client librarys channel->clients table to SilcList and
6286 changed code accordingly.
6288 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * Changed client's channel table to SilcList and changed code
6291 accordingly. Also changed SilcChannelClientEntry to include back-
6292 pointer to the channel so that client entry can use that structure
6293 as list as well and we have fast cross-reference to the channel.
6294 This change dramatically decreased the complexity of channel
6295 handling with client entry and vice versa (removed one extra
6296 loop when searching for channel entry from many functions).
6298 * Changed server->sim from table to SilcDList and changed code
6301 * NAMES command can now be used from user interface. It will show
6302 the user list on the channel, neatly.
6304 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6305 Code now saves realname of the user if it becomes available.
6307 * Renamed configure.in to configure.in.pre and made ./prepare
6308 script to automatically add correct version string to
6309 configure.in which it creates from configure.in.pre.
6311 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6313 * NAMES command reply now shows users mode with the nickname when
6316 * Moved silc_client_ch[u]mode[_char] functions from
6317 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6318 place sucks, they are utility functions and should be in some
6321 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6323 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6326 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6330 * Added TRQ (efficient deque and list library) into lib/trq. This is
6331 a very good list library that is currently used in the SILC. Defined
6332 SilcList API over the library because I didn't like the API very
6333 much. See lib/trq/silclist.h for the API and examples of how to
6334 use the API. Fixed various places in the code to use the new
6335 SilcList API. The SilcList is meant for lists that has a structure
6336 already defined as a list. It is not suitable to add just some
6337 context to the list (in TRQ, the context is the list actually).
6339 So, I defined SilcDList that can be used for the purpose where
6340 predefined list structure does not exit. This can be used as
6341 such list. Now some context just can be added to the SilcDList.
6342 Currently this list is not used in the SILC just yet, though there
6343 are a lot places where this can replace dynamically allocated
6344 tables and I will fix these places, later, to use SilcDList.
6345 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6346 and use TRQ internally).
6348 Also fixed some annoying warning messages that the original TRQ
6349 code generated. Also minor changes to TRQ's Makefile.in.
6351 * Added support for querying by Client ID to both WHOIS and
6352 IDENTIFY commands into server, as required by the protocol.
6354 * Removed method function pointers from SilcBuffer structure. They
6355 weren't used to anything and just increased the context size for
6356 no good reason. This change also made silc_buffer_alloc and
6357 silc_buffer_free functions inline functions.
6359 * Disabled command flooding detection support until it's fixed so
6360 that it accepts commands in but does not execute them more than once
6363 * Added silc_net_localhost(), to return local hostname, into
6364 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6365 that must be initialized before calling silc_client_init.
6367 * Added new function: silc_server_send_notify_on_channels to send
6368 notify messages to all channels client has joined. It is assured
6369 that the message is sent only once per client.
6371 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6372 lib/silcutil/silcutil.[ch] as silc_format function. The new
6373 function is generic and is used by server as well, not only by
6374 the logging routines.
6376 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6377 the provided version string was not acceptable. Added new function:
6378 silc_ske_check_version into lib/silcske/silcske.h. The function
6379 must be implemented by the application (client or server) and it
6380 does not reside in the SKE library. The function checks the version
6381 string remote end sent.
6383 * Added back pointers (to opaque context and to SilcSocketConnection)
6384 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6386 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6387 duplicate packet context structure.
6389 * Changed `notify' client operation to send same arguments as client
6390 receives from server except for ID's. ID's are mapped to correct
6391 ID entry and that is returned. Also, if channel entry is not sent
6392 by server but the notify is for channel the channel entry is sent
6393 to application (otherwise application doesn't know that it is for
6394 channel (library gets it from packet's Destination ID)).
6396 * Added silc_client_remove_from_channels into client library to
6397 remove a client from all channels it has joined to. Used when
6398 received SIGNOFF notify from server. Added also new function
6399 silc_client_replace_from_channels to replace old ID entry with
6400 new ID entry on all channels. Used when received NICK_CHANGE
6403 * Fixed ID Cache list handling in silc_idlist_get_client in
6404 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6405 to get (or query) client by ID.
6407 * Updated TODO list.
6409 * Added connection authentication status message defined by the
6410 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6411 support for these into the code in client and server side.
6413 * Added generic function silc_client_send_command to send any command
6414 with variable argument list. Application should use this function
6415 to send commands if the command functions provided by the library
6416 does not suite for the application's user interface needs.
6418 * Added new `failure' client operation. Application is notified about
6419 received failure packet if client is executing a protocol. In this
6420 case the protocol's execution has failed.
6422 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6423 is required by the protocol.
6425 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6426 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6429 * Added status flag to SilcSKE object to indicate realtime status
6430 of the SKE protocol.
6432 * Application receives now exactly same command reply arguments as
6433 the library receives from server. However, if ID is received the
6434 corresponding ID entry is returned to the application (eg. Client
6435 ID is mapped to correct SilcClientEntry entry and that is returned).
6436 Changed command_reply client operation due to this change.
6438 * Changed all ID's in commands and in command replys as ID Payloads.
6439 Change affected both client and server side codes.
6441 All ID's sent in SILC network (with execption of ID's in SILC
6442 Packet header) are sent in ID Payload to support variable length
6445 * Server now notifies nick changes and notifies all clients on
6446 the channels about the new nickname (about the new Client ID,
6449 * Implemented CMODE command to change channel modes. Supports all
6450 channel modes defined by the protocol specs except ban and invite
6451 lists. (Also, private channel key mode is supported but support for
6452 setting private channel key in client is missing, thus, this mode
6453 has no effect on client side (except that server requires that the
6454 client uses private channel key and normal channel traffic does not
6457 Also, invite mode works per se, but INVITE command does not work
6458 yet correctly, so you can set channel as invite only channel but
6459 inviting clients to the channel does not work (it is yet to be
6460 thought what's the best way to do it).
6462 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6463 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6464 Implemented CUMODE command to change user's mode on the channel.
6465 Supports all modes defined by the protocol specs.
6467 * Added NAMES command reply to return users modes on the channel.
6469 * Removed unnecessary and slow ciphers from lib/silccrypt.
6471 * Set SO_KEEPALIVE option to connection sockets by default.
6473 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6475 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6476 redefined the Notify Payload into protocol specs.
6478 * Added silc_id_payload_parse_id to get ID directly from raw
6481 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6483 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6484 accept searching by Client ID as well.
6486 * Added support for LEAVE and SIGNOFF notify types in client library.
6488 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6489 to parse ID Payload from raw data.
6491 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6493 * Added flags parameter into silc_ske_assemble_security_properties
6494 function in lib/silcske/silcske.[ch].
6496 * Changed notify client operation to fit better for notify messages
6497 sent by server. The notify payload received from server is now
6498 passed to the application (after parsing it to SilcNotifyPayload).
6499 It is application's responsibility to retrieve the arguments
6500 from the payload and show the message the way it wants. The message
6501 sent by server is implementation specific.
6503 * Changed public keys to comply with the protocol specification.
6504 Old public keys are not supported anymore and are not compatible.
6506 * Removed nickname from Channel Payload as the latest draft removed
6507 it. The client must resolve the nickname from the NAMES command
6508 reply received when it joined the channel.
6510 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6512 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6514 * Fixed some errors in protocol specification drafts.
6516 * Created lib/silccore/silcnotify.c to implement Notify Payload
6517 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6518 generic payloads described by protocol specifications. The file
6519 includes implementations for ID Payload and Argument Payload.
6521 * Changed Command Payload implementation to use the new Argument
6522 Payload. Changed command_xxxx_payload to command_payload_xxxx
6523 to comply with SILC coding conventions.
6525 * Added suppport for Argument Payload handling in Notify Payload
6526 implementation as protocol requires it. Added the new support
6527 into server and client lib as well.
6529 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6531 * Added support for multiple nicknames on same channel. [n] is
6532 added locally to the nickname if there are more than one same
6533 nicknames on the channel.
6535 * Server now sends all nicknames that matched WHOIS request.
6536 Client also shows the list received from server.
6538 * Added TOPIC command to client side. User can now set and show
6539 current topic on channel.
6541 * Added MOTD command to client and server. Also, server sends the
6542 motd when client connects to the server.
6544 * Changed version strings to comply ISO 8601.
6546 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6548 * Fixed protocol error handling in client library. It should now
6549 cope even if the SKE fails for some reason.
6551 * Made new protocol specification drafts for submitting to IETF.
6553 * Implemented TOPIC command to server in silcd/command.c.
6555 * Added two new notify types into lib/silccore/silcnotify.h:
6556 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6557 notify nickname change and topic setting/change on a channel.
6559 * API change of command_reply operation in client library. The
6560 application gets now the status type received from server as well.
6562 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6564 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6566 * Cras fixed and optimized the packet handling even further and
6567 it should work now. Minor change to the prototype of function
6568 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6570 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6572 * Added new function into lib/silcutil/silcschedule.[ch]:
6573 silc_schedule_with_fd to select() a specified fd. The function
6574 returns after timeout expires or data arrives or goes. The
6575 function is used by packet routines to wait that all data is
6576 received from network.
6578 * Fixed data reading from network in lib/silccore/silcpacket.c.
6579 The code now assures that all data is read from the fd and then
6580 continues packet processing. This was a bug fix since the code
6581 used to drop some data in some circumstances.
6583 * Added new function into lib/silcclient/client.[ch]:
6584 silc_client_start_key_exchange to start key exchange after
6585 connection has been established to server. The code internally
6586 now uses this funtion but its main purpose was to provide it
6587 for applications that perform their own connecting. After
6588 application has created a connection it merely calls this
6589 function to start the key exchange between client and server.
6590 The library takes care of everything else after that.
6592 Updated also lib/silcclient/README to explain the usage of
6595 * Do not send to application information that connection has
6596 been established. Application gets notified it by connect
6599 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6601 * Applied cras's patch to add silc_schedule_one function. The
6602 function runs scheduler once and returns.
6604 * Fixed the scheduler after cras messed it up. The timeout
6605 handling works now as it's supposed to work.
6607 * Added into lib/silccore/ silcnotify.h to include notify
6608 message types support. Changed silc_server_send_notify*
6609 functions, in server.[ch], to support those new notify types.
6610 Added the support for the notify types into client library,
6611 as well. Added new notify client operation into ops.h in
6614 * Changed silc_server_packet_send_to_channel to send normal
6615 packets instead of just channel message packets. The function
6616 is now used to send the notify packets to channels. It is not
6617 used to send channel message packets anymore, as server never
6620 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6621 va_arg()s as it seems to require it nowadays. I guess, if SILC
6622 is compiled with older va_arg() the new code should work anyway.
6624 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6626 * Splitted core library. Core library (lib/silccore) includes
6627 now only SILC protocol specific core (and common) components.
6628 Created new utility library (lib/silcutil) that includes more
6629 generic purpose stuff. The stuff for util library was taken
6630 from the old core library. This was minor and easy split.
6632 * Created SILC Client Library (lib/silcclient) that includes
6633 implementation of the SILC client without user interface. This
6634 was major move from silc/ directory. The code has been changed
6635 so that it is transparent towards the user interface. The
6636 silc/ directory includes now the same user interface as before
6637 and it uses the new client library. Read lib/silcclient/README.
6638 Basicly, the client library performs everything else related
6639 to SILC except user interface handling. Also, configuration
6640 files are considered to be part of user interface and library
6641 does not handle them.
6643 This change also changed a lot of structures, function naming etc.
6644 Most important change was that SilcClientWindow object was
6645 renamed to SilcClientConnection in the client library. Created
6646 also new file lib/silcclient/ops.h. Also added new files
6647 silc/local_command.[ch] and silc/client_ops.[ch].
6649 All these changes were made to make it easier for user interface
6650 designers to create what ever user interface for the SILC client
6653 It is also expected that the server will be moved to lib
6654 directory as well and SILC Server Library will be created;
6655 sometimes in the future.
6657 * Removed Local commands from lib/silccore/silccommand.h as
6658 they are application specific and new client library does not
6659 handle any of those anymore.
6661 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6662 old client implementation in silc/.
6664 * Added support for callback functions in SILC_LOG_* macros.
6665 Application can now set its own callbacks that will be called
6666 instead of using the default functions that will always print
6667 the debug messages to stderr (or stdout). Also, debugging can
6668 now be disabled by setting silc_debug to FALSE and re-enabled by
6669 setting it to TRUE. Note, that logging will still work even
6670 if debugging is disabled.
6672 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6673 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6674 silc_log_reset_debug_callbacks.
6676 * To enable debugging in silc client one must give now -d
6677 option on command line.
6679 * Changed silc_schedule_init to automatically allocate task queues
6680 if they are not allocated before calling it.
6682 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6684 * Added GMP 3.1 into math library.
6686 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6688 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6689 a channel in SILC network. The packet is used by servers and
6690 routers to notify other routers that user has left a channel.
6691 This little feature was missing until now. Added the feature
6692 to protocol specification as well.
6694 Added functions: silc_server_send_remove_channel_user and
6695 silc_server_remove_channel_user into server.[ch].
6697 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6698 lib/silccore/silcpacket.h. However, they are not implemented
6701 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6703 * Fixed joining to a channel and sending channel messages
6704 between server and router. The channel message sending should
6705 now work inside a cell.
6707 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6709 * Fixed the private message sending between server and router.
6710 The private message sending should now work inside a cell.
6712 * Added silc_server_replace_id into server.[ch] to replace
6713 existing ID in the SILC network.
6715 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6716 and silc_idlist_replace_server_id into idlist.[ch] in server.
6718 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6720 * Fixed the server to server connections. Server can again now
6721 connect to router. Router to router connections probably does
6724 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6726 * Added dynamic protocol registering support. Now protocols can
6727 registered and unregistered on the fly. Patch by cras.
6729 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6731 * Added lib/contrib directory to hold routines that some platforms
6732 don't have but are needed by SILC.
6734 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6735 into lin/contrib to provide getopt() and getopt_long() for
6736 those who don't have it.
6738 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6740 * Added AWAY command to client. When away message is set and
6741 client receives a private message packet the client automatically
6742 replies to the sender with the away message.
6744 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6745 bug seemed to be the cause of recent problems when compiling
6748 * Added version detection support to SKE protocol specification
6749 and added the new changes to the SKE implementation as well.
6750 There were other minor changes in the SKE protocol as well.
6752 Many changes in lib/silcske/silcske.[ch] and in
6753 lib/silcske/payload.[ch].
6755 * Added ^U functionality, clear input line. Patch from cras.
6757 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6759 * Mainly small bugfixes on core library. Fixed some debugging
6760 logging and buffer overflow in silclog.c.
6762 * Updated config.sub and config.guess on the distribution tree.
6764 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6766 * Added command lagging support in server. Client may execute
6767 commands now only once in two seconds.
6769 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6771 * Optimized packet reception. MAC computation and checking is now
6772 also more optimized. A lot previously duplicated code is now
6773 used as generic by both client and server.
6775 * Fixed key pair generation in clientutil.c
6777 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6779 * Added into lib/silccore/silcbufutil.[ch] new function;
6780 silc_buffer_realloc.
6782 * Moved generic packet sending/encryption functions to
6783 lib/silccore/silcpacket.[ch] from client and server. Some
6784 rewriting of the functions.
6786 * Moved all generic packet reception/decryption functions to
6787 lib/silccore/silcpacket.[ch] from client and server. The
6788 packet processing is now much cleaner in both client and server.
6789 These were major changes in both client and server.
6791 * Created many common functions in server to do packet sending.
6792 Previously code were duplicated a lot, this has been removed
6795 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6797 * Rewrote major parts of the ID cache system. Don't know
6798 whether it is better now or not but at least the API is more
6801 * Major rewrite on ID cache stuff on client because of the ID
6802 cache API changes. Added idlist.c to client.
6804 * Also major rewrite on ID cache stuff on server as well.
6805 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6806 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6807 in hand, instead they are all put into the ID cache system now.
6808 All server_idlist_* routines uses ID cache now instead of
6809 traversing its own lists (those lists does not exist anymore).
6810 SilcIDList though still exists. Also, SilcXXXEntry's are
6813 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6815 * Finally made the SKE implementation compliant to the protocol
6816 specification. All mp integers are now binary encoded as
6817 opposed being HEX encoded.
6819 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6822 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6823 functions: silc_[encode/decode]_pem. Also added function
6824 silc_encode_pem_file to PEM encode with newlines ('\n') for
6827 * SILC public keys are now encoded either PEM or binary. Same
6828 option is for private keys as well. By default private keys
6829 are binary encoded and public keys PEM encoded. Silly HEX
6830 encoding were removed.
6832 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6833 function to create fingerprints.
6835 * Fixed a bug in SHA1; does not change the original data anymore.
6837 * Partly implemented INFO command on client and server side.
6838 Fixed CLEAR command. Changes to SERVER command; show current
6839 server(s) when giving command without arguments. Added
6840 VERSION command to client.
6842 * Added check to server that unregistered connections cannot
6843 execute commands (unless it is specificly allowed).
6845 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6847 * Fixed screen refresh.
6849 * Fixed channel joining bug from client. On some circumstances
6850 client tried to join to a channel it had already joined.
6852 * Added public key verification process into client's protocol.c.
6853 The client now verifies the public key from user and saves
6854 it into ~./silc/serverkeys/ directory.
6856 Added into: clientutil.[ch]: silc_client_verify_server_key.
6858 * Changed SKE protocol's silc_ske_initiator_finish function
6859 to accept callback function that verifies the received public
6860 key. Removed old silc_ske_verify_public_key function.
6862 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6864 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6865 silc_pkcs_private_key[_data]_set.
6867 * Made the password and public authentication more cleaner in
6868 server's protocol.c.
6870 * Removed historic and obsolete protocol `channel_auth' from
6871 both client and server.
6873 * Removed wrong way of sending command status messages from
6874 server to client in server's command.c. The old way violated
6875 protocol specification.
6877 Changes to silccore/silccommand.[ch]: removed
6878 silc_command_encode_status_payload -> not needed anymore,
6879 changed silc_command_encode_payload_va to accept extra
6880 argument on variable argument list. The argument type must
6881 now be provided to the function. Also, added new function:
6882 silc_command_encode_reply_payload_va which is same as
6883 normal command_encode_payload_va except command status type
6884 is provided as extra argument.
6886 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6888 * Added ~./silc directory handling. The directory includes the
6889 public and private keys for the client.
6891 Added silc_client_check_silc_dir, silc_client_create_identifier
6892 and silc_client_load_keys.
6894 * Implemented SILC protocol compliant public key. Added public
6895 and private key saving to and loading from files.
6897 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6898 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6899 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6900 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6901 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6903 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6904 silc_pkcs_load_[public/private]_key.
6906 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6908 * Added silc_server_get_route (route.[ch]) to get connection
6909 data for the fastest route for given ID.
6911 * Implemented INVITE command on client and server. The command
6912 were re-defined in the SILC Protocol Specification and the
6913 implementation now complies with the specification.
6915 * Implemented PING command on client and server.
6917 * Implemented NAMES command on client and server. The server side
6918 supports currently only normal server not router server yet.
6919 Some changes to NAMES definition in SILC protocol specification.
6921 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6923 * Implemented LEAVE command on client and server.
6925 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6926 again. This change was made to the protocol as well. Server
6927 should not violate the protocol specification anymore.
6929 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6931 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6932 was tested. SOCKS4 was not but should work anyway.
