1 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed CUMODE_CHANGE notify handling to change the mode of
4 correct client. Affected file lib/silcclient/client_notify.c.
6 * Make silc_rng_alloc fail if it cannot allocate the sha1
7 hash algorithm. Affected file lib/silccrypt/silcrng.c.
9 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
11 * Fixed the file transfer's key agreement payload to include
12 zero port also if the hostname is NULL because it could not
15 Call file transfer monitor callback now also if error occurs
16 during key agreement protocol.
18 Changed the silc_client_file_send interface to return the
19 SilcClientFileError instead of session id. The session ID
20 is returned into pointer provided as argument.
22 Check that the file exists locally before sending the
23 file transfer request at all.
25 Affected file lib/silcclient/client_ftp.c, silcapi.h.
27 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
28 error than can occur while key agreement protocol. Affected
29 file lib/silcclient/silcapi.h.
31 * Fixed the event_mode CMODE handler to not crash when mode
32 is changed and +k mode is set in the channel. Affected file
33 irssi/src/silc/core/silc-channels.c.
35 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
36 SILC_LOG_WARNING to give out Warning and not Error. Affected
37 file lib/silcutil/silclog.c.
39 * Fixed the channel message payload decryption in the function
40 silc_channel_message_payload_decrypt to not modify the original
41 buffer before it is verified that the message decrypted
42 correctly. Otherwise, next time it is called with correct
43 channel key it won't encrypt since the payload is corrupted.
44 Affected file lib/silccore/silcchannel.c.
46 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
48 * Do not constantly resize the window. A fix patch by cras.
49 Affected file irssi/src/fe-text/screen.c.
51 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
53 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
54 Affected file lib/silcutil/silcnet.c.
56 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
58 * Fixed a bug in hash table internal routine for traversing
59 the table with foreach callback. The current entry may
60 become invalid in the callback but it was referenced after
61 the callback returned.
63 Do not allow auto rehashing of hash table during the
64 silc_hash_table_foreach operation, for same reasons as it is
65 not allowed for SilcHashTableList. Affected files are
66 lib/silcutil/silchashtable.[ch].
68 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
70 * Defined DLLAPI into silcincludes.h and silcwin32.h for
71 Win32 DLL. extern's in header files are now declared with
74 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
76 * Fixed private message handling. It used some old code that
77 caused the client to crash. Affecte file is
78 lib/silcclient/client_prvmsg.c.
80 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
82 * Added function silc_client_add_channel,
83 silc_client_replace_channel_id, and removed functions
84 silc_client_new_channel_id and silc_idlist_get_channel_by_id
87 * Added cross reference of the joined channels to the
88 SilcClientEntry, and changed the SilcChannelEntry's
89 users list to SilcHashTable. The affected files are
90 lib/silcclient/idlist.[ch].
92 * Fixed a bug in hash table tarversing. While the hash table
93 is traversed with SilcHashTableList the table must not be
94 rehashed. It is now guaranteed that auto rehashable tables
95 are not rehashed while tarversing the list. Also defined that
96 silc_hash_table_rehash must not be called while tarversing
97 the table. Added function silc_hash_table_list_reset that must
98 be called after the tarversing is over. The affected files are
99 lib/silcutil/silchashtable.[ch].
101 * Changed all hash table traversing to call the new
102 silc_hash_table_list_reset in server and in client library.
104 * Added function silc_client_on_channel to return the
105 SilcChannelUser entry if the specified client entry is joined
106 on the specified channel. This is exported to application as
107 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
109 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
111 * Fixed founder regaining problem with JOIN command on normal
112 server. The notify for mode change must be sent always and
113 not only if !cmd->pending. Affected file silcd/command.c.
115 * Fixed the WHOWAS command's reply sending to support the
116 lists correctly. Affected file silcd/command.c.
118 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
120 * When sending JOIN command to router for processing the
121 sender's old command identifier was not saved back to the
122 sender's command context, fixed now. The affected file is
125 * Create the key in JOIN command of the router did not return
126 the channel key, added check for this. Affected file is
129 * Fixed a channel ID update bug in JOIN command reply. Do
130 not directly upgrade the ID but call the function
131 silc_idlist_replace_channel_id if the ID was changed.
132 Affected file silcd/command_reply.c.
134 * Fixed memory leaks from command calling if it would fail.
135 Affected file silcd/command.c.
137 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
139 * Applied patches from cras:
141 Memory leak fixes around libaries, irssi window resize fix,
142 new silclist.h and silcdlist.h, all extern inline changed to
145 * Removed dotconf from lib/dotconf, not needed anymore.
147 * Removed TRQ from lib/trq, not needed anymore.
149 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
150 with server connections. Later this will be configurable
151 in config file after new config file is done. Affected file
154 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
156 * Fixed a crash in server related to channel announcements.
157 Affected file silcd/server.c.
159 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
161 * Fixed memory leaks in silc_server_create_new_channel*
162 functions. Affected file silcd/server.c.
164 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
165 which ID was changed. This way the router will send the
166 user list for the channel again, and server won't be in
167 desync in some rare circumstances. Affected file is
168 silcd/packet_receive.c.
170 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
172 * Check for NULL socket pointer in the function
173 silc_server_packet_send_to_channel_real. Affected file
176 * Fixed the BAN notify handling to correctly remove ban
177 list. Affected file silcd/packet_receive.c.
179 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
181 * Fixed some header addition to Toolkit distribution in
182 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
184 * Added lib/silcclient/client_ops_example.h as an template
185 file for application programmers to quickly start using
186 the SilcClientOperation functions in their application.
187 Updated the lib/silcclient/README as well to tell about this
188 nice file made available.
190 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
192 * Call silc_server_remove_from_channels when removing client
193 entry when NO_SUCH_CLIENT_ID was received. Affected file
194 is silcd/command_reply.c.
196 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
198 * Added server & router operator statistics updating. Affected
199 file silcd/packet_receive.c and silcd/command.c.
201 * Fixed the SERVER_SIGNOFF notify handling on normal server
202 not to save the history information for clients. Same was
203 fixed earlier in remove_clients_by_server function, but not
204 here. Affected file silcd/packet_receive.c.
206 * Raised the default connection-retry count from 4 to 7 in
207 server. Affected file silcd/server.h.
209 * Cancel any possible reconnect timeouts when we start the
210 key exchange. Affected file silcd/server.c.
212 * Do not reconnect on connection failure when SCONNECT was
213 given. Affected files silcd/server.[ch].
215 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
217 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
219 * Fixed the NICK command to always give the unformatted
220 nickname to the one giving the NICK command. If unformatted
221 nickname is cached already it will be formatted and the
222 local entry will always get the unformatted nickname.
223 Affected file lib/silcclient/idlist.c.
225 * Fixed some double frees from client library commands.
226 Affected file is lib/silcclient/command.c.
228 * Fixed CUMODE command in server to assure that no one can
229 change founder's mode than the founder itself, there was a
230 little bug. Affected file silcd/command.c.
232 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
234 * Removed the SilcClientCommandDestructor from the client
235 libary, it is not needed anymore. Affected files are
236 lib/silcclient/silcapi.h, command[_reply].[ch],
237 client_notify, idlist.c.
239 * Fixed GETKEY command to first resolve client, and then
240 resolve the server only if the client was not found, instead
241 of resolving both at the same time. Affected file is
242 lib/silcclient/command.c.
244 * Added silc_client_start_key_exchange_cb and lookup the
245 remote hostname and IP address before starting the key
246 exchange with server. The affected file is
247 lib/silcclient/client.c.
249 * The server's public key is now saved using the IP address
250 of the server and not the servername for the filename.
251 The hostname public key filename is checked as an fall back
252 method if the IP address based filename is not found.
254 Fixed the GETKEY command to save the fetched server key
257 Print the remote server's hostname now when new key is
258 received during connection process. Affected file is
259 irssi/src/silc/core/client_ops.c.
261 * Return always our own public key to the client if it asks
262 for it with GETKEY command. Affected file silcd/command.c.
264 * Removed the use_auto_addr variable from default config
265 file since it was in wrong section. Affected file is
268 * Fixed TOPIC_CHANGE notification to not route it when it
269 was sent using silc_server_send_notify_to_channel function.
270 Affected file silcd/command.c.
272 * Fixed silc_server_send_notify_kicked to send the kicker's
273 Client ID also, it was missing. Affected files are
274 silcd/command.c, silcd/packet_send.[ch].
276 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
278 * Do not save client history information in SERVER_SIGNOFF.
279 Fixes the bug in normal server that it does not detect
280 the client becoming valid after the server becomes back
281 online. Affected file silcd/server_util.c.
283 * Added `sock_error' field into the SilcSocketConnection
284 context. When error occurs during socket operation (read
285 or write) the error is saved. Added also new function
286 silc_socket_get_error to return human readable socket error
287 message. Affected files are lib/silcutil/silcsockconn.[ch],
288 lib/silcutil/unix/silcunixsockconn.c, and
289 lib/silcutil/win32/silcwin32sockconn.c.
291 * The server now prints the socket error message in the
292 signoff for client. Affected file silcd/server.c.
294 * Fixed the `created' channel information sending from router
295 to server in JOIN command. Checks now whether the channel
296 really was created or not and set it according that.
298 Fixed the JOIN command to use the client entry's current
299 ID during the joining procedure instead of the one it sent
300 in the command (it is checked though), since it can change
301 between the packet processing and command processing, and
302 would just case unnecessary pain in the client end. Affected
303 file silcd/command.c.
305 * Fixed a channel key payload sending to use correct channel
306 ID when the server was forced to change the channel's ID by
307 router. Router sent the key payload with the old Channel ID.
308 Affected file silcd/packet_receive.c.
310 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
312 * Call silc_server_save_channel_key only if the key payload
313 was provided in the JOIN command's command reply. Affected
314 file silcd/command_reply.c.
316 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
318 * Fixed silc_mp_sizeinbase to return the value correctly with
319 MPI. Affected file lib/silcmath/mp_mpi.c.
321 * Fixed the stop_server signal to correctly stop the scheduler
322 and gracefully stop the server when SIGTERM or SIGINT signals
323 are received. Affected file silcd/silcd.c.
325 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
327 * Simple handling of TERM and HUP signals. Also added some log
328 flushing call around. Affected file is
331 * Fixed small bugs in silclog.c. Now buffering output will take
332 effect after 10 seconds since startup: This will ensure that
333 no important startup messages are lost. Also output redirection
334 will preserve original format ([Date] [Type] message).
335 Affected file is lib/silcutil/silclog.c.
337 * Added two options to the config file, in the logging section:
338 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
339 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
341 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
343 * Do not print the warning about log files not being initialized
344 more than once to avoid excess logging. Affected file is
345 lib/silcutil/silclog.c.
347 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
348 the SIM copying in make install in Makefile.am.pre.
350 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
352 * Rewritten silclog APIs. Globally interesting changes follows:
353 silc_log_set_files() changed to silc_log_set_file().
354 silc_log_set_callbacks() changed to silc_log_set_callback().
355 ROBOdoc documented silclog header file.
356 SilcLogCb now returns bool to wether inihibit the default
357 handler or not (to keep the old behaviour return always TRUE).
358 The new APIs should also fix the problem of the
359 silcd_error.log file that was written in the current directory.
362 Log files streams will remain opened after silc_log_set_file()
363 call, means less CPU usage notably on high traffic servers.
364 File streams are now full buffered, and flushed to the disk
365 every 5 minutes, lesses HD activity and CPU usage.
366 Messages can be redirected, allowing admins to configure
367 one single logfile for all server messages.
368 the silc_log_quick global variable to activate fast-logging.
369 Affected files lib/silcutil/silclog.[ch]
371 * Changed some code to conform new silclog APIs. Affected
372 files are doc/example_silcd.conf.in, silcd/server.c
373 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
376 * Fixed a memory leak that could occur in some situations.
377 Affected file silcd/serverconfig.c.
379 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
381 * Added the silc_client_del_client to remove the client from
382 all channels as well. Affected file lib/silcclient/idlist.c.
384 * Fixed the client library to correctly remove the client
385 from all channels when the client entry is being destroyed.
386 Affected file lib/silcclient/client_notify.c, command.c.
388 * Added auto-nicking support to the client library. If the
389 applicatio now sets client->nickname it will be sent to the
390 server after connecting by the library. This way for example
391 SILCNICK (or IRCNICK) environment variables will have effect
392 and always change the nickname automatically to whatever
393 it is wanted. Affected file lib/silcclient/client.[ch].
395 * Renamed silc_server_command_bad_chars to the
396 silc_server_name_bad_chars and moved it to the
397 silcd/server_util.[ch]. Added also new function
398 silc_server_name_modify_bad to return nickname that
399 includes bad characters as new nickname without those
400 bad characters. This check and modify is now used in
401 silc_server_new_client when the username is initially set
402 as nickname, so it must be checked to be valid nickname.
403 Affected file silcd/packet_receive.c.
405 * The nickname length is now taken from the packet for real
406 and not trusted to strlen() since it clearly can return
407 wrong length for nickname including bad characters. This
408 also applies to channel names. Affected file silcd/command.c.
410 * Removed the lib/silcsilm/modules directory. Modules are now
411 compiled into the lib/silcsim. Fixed the copying of the
412 modules to follow symbolic links in Makefile.am.pre.
414 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
416 * Fixed silc_string_regexify list creation. Fixes bugs with
417 BAN and INVITE commands in server. The affected file is
418 lib/silcutil/unix/silcunixutil.c.
420 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
422 * Removed the command destructor entirely from the server's
423 command and command reply routines. It is not needed, and
424 its usage was buggy and caused crashes. Affected files are
425 silcd/command[_reply].[ch].
427 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
429 * Cancel protocol and NULL sock->protocol if timeout
430 occurred during protocol. Affected file silcd/server.c.
432 * Cancel protocol timeouts always before calling the final
433 callback, to assure that after final callback is called
434 no other state will be called for the protocol anymore.
435 Affected file silcd/protocol.c.
437 * Print error log if incoming connection configuration could
438 not be found. Affected file silcd/server.c.
440 * Fixed JOIN command to correctly save the founder mode
441 to the client on normal SILC server, when the channel
442 was created by the router. Affected file silcd/command.c.
444 * Fixed LIST command (hopefully) to send correct reply
445 packets. Affected file silcd/command.c.
447 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
449 * The silc_packet_receive_process now returns FALSE if the
450 read data was invalid packet, and TRUE if it was ok.
452 The server now checks that if unauthenticated connection
453 sends data and its processing fails the server will close
454 the connection since it could be a malicious flooder.
456 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
458 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
460 * Make sure the warning about error opening a log file is
461 printed only once and not everytime it fails (produces
462 too much useless log). Affected file lib/silcutil/silclog.c.
464 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
466 * Made the silc_server_daemonise() function more readable.
467 Affected file silcd/server.c.
469 * Pid file is now optional, the user may comment it out from
470 the config file. Removed define SILC_SERVER_PID_FILE, we
471 don't need a default any longer. Affected file
472 configure.in.pre, lib/Makefile.am.pre.
474 * Make some use of the pid file. The server now dies at startup
475 if it detects a valid pid file on his path. The server would
476 die anyway in this circumstance, because of the bind() failure.
477 Affected file silcd/silcd.c.
479 * No longer compiling lib/dotconf.
481 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
483 * Fixed JOIN command parsing not to crash. Affected file
484 lib/silcclient/command.c.
486 * Fied the NICK_CHANGE notify to add the new client entry
487 even it is resolved. This removes an <[unknown]> nick
488 thingy bug in the client. Affected file is
489 lib/silcclient/client_notify.c.
491 * Do not try to allocate 0 bytes (efence does not like it)
492 in lib/silccore/silccomand.c when encoding payload.
494 * Do not take IRCNICK as nickname in Irssi SILC client since
495 it is not possible to set nickname before hand connecting
496 the server (TODO has an entry about adding auto-nicking
499 * Changed the silc_server_command_pending to check whether
500 there already exists an pending entry with the specified
501 command, command identifier and pending callback. This is
502 to fix IDENTIFY and WHOIS related crashes that may register
503 multiple pending commands with same identifier. Affected
504 file silcd/command.c.
506 * Fixed the server to reconnect to the router even if it
507 was already reconnecting and EOF was received. This to
508 fix a possibility that the server wouldn't ever try to
509 auto-reconnect to the router. Affected file silcd/server.c.
511 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
513 * Fixed the server's password authentication to use the
514 length of the locally saved password, and not the one
515 sent in the packet. Affected file silcd/protocol.c.
517 * Fixed same password authentication problem in the
518 Authentication Payload handling routines in
519 lib/silccore/silcauth.c.
521 * Yet another password authentication problem fixed with
522 channel password handling in silcd/command.c.
524 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
526 * If first character of string in silc_parse_userfqdn is '@'
527 then do not parse it. Affected file is
528 lib/silcutil/silcutil.c.
530 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
532 * Fixed minor bug in IDENTIFY command reply sending, which
533 caused various weird problems during JOIN when it was
534 resolving names for users. Affected file silcd/command.c.
536 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
538 * Fixed the IDENTIFY command reply sending to chech better valid
539 clients. It was possible to send incomplete list of replies.
540 Affected file silcd/command.c.
542 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
544 * Added silc_client_command[s]_[un]register functions now to
545 dynamically register the commands in client library. Removed
546 the static table of commands. This allows the client library
547 to call commands without causing the application to know about
548 what commands library has called.
550 Removed the INFO command reply kludge to detect when the command
551 was called by library. Now library use its own command reply
552 function for INFO command.
554 Added function silc_client_command_call to call a command.
555 Application can use it to call command, not access the structure
558 Now all commands that are sent by the client library (not
559 explicitly sent by application) use own command reply functions.
561 Affected files around lib/silcclient/ and in
562 irssi/src/silc/core/.
564 * Fixed the WHOIS command reply sending to chech better valid
565 clients. It was possible to send incomplete list of replies.
567 Fixed the WHOIS and IDENTIFY to send the request to router
568 if normal server did not do it and did not find any results.
570 Affected file silcd/command.c.
572 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
574 * Moved the internal data from SilcClient context into its
575 own file, not accesible to application. Affected files
576 lib/silcclient/client.h and lib/silcclient/client_internal.h,
577 and other files in client library.
579 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
581 * Added doc/examples installation target in Makefile.am.pre.
584 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
586 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
587 commands the found client entry will be removed from the
588 cache, after notifying application about the error. Affected
589 file lib/silcclient/command_reply.c.
591 * Changed the /MSG to check for exact nickname user gave, and
592 not let `nick' match `nick@host' if it is only one found. Now,
593 user must type the exact nickname (like nick@host2) even if
594 there are no more than one same nicks found. This is to avoid
595 a possibility of sending nickname to wrong nickname since
596 `nick' could match `nick@host'. Affected file is
597 irssi/src/core/silc-servers.c.
599 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
601 * Do not print "you are now server operator" or similar when
602 giving /away command. Affected files are
603 irssi/src/silc/core/client_ops.c, silc-servers.h.
605 * Made the silc_server_command_pending_error_check to send
606 the same command reply payload it received back to the
607 original sender of the command. This way all arguments
608 that was received by the server will be received by the
609 client too. Affected file silcd/command.c.
611 * Added the silc_idcache_add to return the created cache entry
612 to a pointer. Affected file lib/silccore/silcidcache.[ch].
614 * Add global clients to expire if they are not on any channel.
615 This is because normal server will never know if they signoff
616 if they are not on any channel. The cache expiry will take
617 case of these entries. This is done by normal servers only.
618 The affected files are silcd/command_reply.c,
619 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
621 * If server receives invalid ID notification for WHOIS or
622 IDENTIFY and the ID exists in the lists, it is removed.
623 Affected file silcd/command_reply.c.
625 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
626 in client then client entry that it matches is searched and
627 the nickname is printed on the screen for user. Affected
628 file irssi/src/silc/core/client_ops.c.
630 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
632 * Use cache entry expire time in the LIST command reply to
633 purge old entries from the cache after the LIST command
634 reply has been received. This way we don't have non-existent
635 entries in the cache for too long. Affected file is
636 silcd/command_reply.c.
638 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
640 * If we are normal server, and we've not resolved client info
641 in WHOIS or IDENTIFY from router, and it is global client,
642 we'll check whether it is on some channel. If it is not
643 then we cannot be sure about its validity and will resolve it
644 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
645 file silcd/command.c.
647 * Search channel by name (if possible) rather than by ID
648 in IDENTIFY command's command reply. Affected file is
649 silcd/command_reply.c.
651 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
653 * Distribute to the channel passphrase in CMODE_CHANGE notify.
654 Updated specs and implemented it. Affected file silcd/command.c,
655 silcd/packet_send.c and silcd/packet_receive.c.
657 * Implemented the <founder auth> payload handling in the JOIN
658 command. If provided all conditions for channel joining
659 except requirement to provide correct passphrase can be
660 overrided by the channel founder. Updated the protocol specs.
661 Affected file silcd/command.c.
663 Added support for founder auth in JOIN command in client
664 library. Fixed the parsing of the JOIN command now to support
665 all options as they should be. The affected file is
666 lib/silcclient/command.c.
668 * Optimized the WHOIS and IDENTIFY commands to send the request
669 to router only if it includes nicknames or other names. If
670 they include only IDs then check the local cache first before
671 routing. Affected file is silcd/command.c.
673 * Added channels topic announcements. Affected file is
674 silcd/packet_receive.c and silcd/server.c.
676 * Fixed the silc_server_send_notify_topic_set to really destine
677 the packet to channel. Affected file silcd/packet_send.c.
679 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
680 library. Affected file lib/silcclient/client_notify.c.
682 * Added UMODE announcements. Affected file silcd/server.c.
684 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
686 * Memory leak fixes in:
688 lib/silcutil/silcsockconn.c
689 lib/silcske/silcske.c
692 lib/silccrypt/silcpkcs.c
693 lib/silccore/silccommand.c
694 lib/silccore/silcidcache.c
699 * ROBOdoc documented the lib/silcske/groups.h file and a
700 bit changed the interface for better.
702 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
704 * Update the client entry context in the ID cache after
705 nick change. Affected file lib/silcclient/command.c.
706 Fixes the CUMODE command when regaining founder privileges,
707 and a little WHOIS problem.
709 * Fixed silc_net_gethostbyname to correctly call the
710 inet_ntop. Affected file lib/silcutil/silcnet.c.
712 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
714 * Added IPv6 support checking to the configure.in.pre, added
715 also --enable-ipv6 option to override the check. Affected
716 file configure.in.pre.
718 * The silc_thread_create now calls the start function
719 directly if threads support is not compiled in. Removes
720 ugly #ifdef's from generic code. Affected files are
721 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
723 * Added silc_net_gethostby[name/addr]_async to asynchronously
724 resolve. Affected files are lib/silcutil/silcnet.[ch].
726 * Added support for rendering IPv6 based server, client and
727 channel IDs. Affected file lib/silcutil/silcutil.c.
729 * Added support for creating IPv6 based server IDs. Affected
730 file is silcd/serverid.c.
732 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
734 * Added silc_net_gethostby[addr/name] into the
735 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
736 routines. Added silc_net_is_ip[4/6]. Affected file is
737 lib/silcutil/unix/silcunixnet.c. All routines that take
738 address as argument now supports both IPv4 and IPv6 addresses.
740 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
742 * Fixed LIST command reply sending in server. Affected file
745 * Server now sends the kicker's client ID in the KICK notify
746 to the kicked client. Affected file silcd/command.c.
748 * The client library now parses the kickers client ID and
749 UI displays it. Affected files lib/silcclient/client_notify.c
750 and irssi/src/silc/core/silc-channels.c, module-formats.c.
752 * Made all payload parsing function prototypes consistent.
753 They all take now const unsigned char * and uint32 pair as
754 the payload data instead of SilcBuffer. Changes all around
755 the source tree. Other unsigned char* -> const unsigned char*
756 changes around the tree as well.
758 * Optimized SFTP client and server packet sending not to
759 allocate new buffer for each packet but to recycle the
760 first allocated buffer. Affected files are
761 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
763 * Optimized the SFTP client to use SilcList instead of
764 SilcDList for requests, because it is faster. Affected file
765 is lib/silcsftp/sftp_client.c.
767 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
768 into lib/silccore/silcid.[ch].
770 Renamed silcpayload.[ch] into silcargument.[ch].
772 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
774 * If client entry is deleted with active key agreement
775 session, abort the session.
777 The silc_client_abort_key_agreement now calls the completion
778 callback with new SILC_KEY_AGREEMENT_ABORTED status.
780 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
783 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
785 * Don't use __restrict in older GCC's. Affected file is
786 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
788 * silc_net_localhost now attempts to reverse lookup the
789 IP/hostname. Affected file lib/silcutil/silcnet.c.
791 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
792 command. It can be used to gain founder privileges at
793 the same time when joining the channel.
795 Defined that the SILC_NOTIFY_TYPE_KICKED send the
796 kicker's client ID as well. Updated protocol specs.
798 Defined that the server must send SILC_COMMAND_IDENTIFY
799 command reply with error status to client who sent
800 private message with invalid client ID.
802 Updated the protocol specification.
804 * Added silc_server_send_command_reply to send any
805 command reply. Affected file silcd/packet_send.[ch].
807 * Added silc_id_payload_encode_data to encode ID payload
808 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
810 * The server now send IDENTIFY command reply with error
811 status if client ID in private message is invalid. Affected
812 file silcd/packet_receive.c.
814 * Save the server key file with server's IP address in
815 the filename instead of hostname. The affected file is
816 irssi/src/silc/core/client_ops.c.
818 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
820 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
823 * Added libtool support for compiling shared objects in
824 lib/silcsim. Affected file configure.in.pre and
825 lib/silcsim/Makefile.am. Original patch by cras.
827 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
829 * Pid file configuration, and server's config file fixes
830 patch by toma. Updated CREDITS file.
832 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
834 * Fixed silc_client_channel_message to not try to decrypt
835 the message twice if it resolved the destination client
836 information. This could cause of dropping one channel
837 message. Affected file lib/silcclient/client_channel.c.
839 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
841 * Added silc_client_run_one into lib/silcclient/silcapi.h and
842 lib/silcclient/client.c. This function is used when the SILC
843 Client is run under some other scheduler, or event loop or
844 main loop. On GUI applications, for example this may be
845 desired to used to run the client under the GUI application's
846 main loop. Typically the GUI application would register an
847 idle task that calls this function multiple times in a second
848 to quickly process the SILC specific data.
850 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
852 * Fixed silc_server_drop() for dropping the supplementary
853 groups as well, this could cause a security hole on some
856 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
858 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
861 * Write PID file after dropping privileges. Added -F option
862 to run server on foreground. A patch by debolaz.
863 Affected files silcd/server.c, silcd/silcd.c.
865 * Fixed MOTD to return the MOTD file server name. Affected
866 file silcd/command.c.
868 * Added INFO command reply handling to the Irssi SILC Client.
869 Affected file irssi/src/silc/core/client_ops.c.
871 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
873 * Fixed the silc_idcache_list_* routines to really support
874 the dynamic list. Fixes a crash. Affected file is
875 lib/silccore/silcidcache.c.
877 * Fixed the LIST command reply to really call LIST command's
878 pending callbacks. Affected file silcd/command_reply.c.
880 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
882 * Update conn->local_entry->nickname after giving NICK
883 command. Affected file lib/silcclient/command.c.
885 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
887 * Added the [pid] option to the silcd configuration file
889 Affected files: serverconfig.[ch] and silcd.c
891 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
893 * Save fingerprint in WHOIS command reply in server.
894 Affected file silcd/command_reply.c.
896 * Fixed NICK commands pending callback registration.
897 Affected file lib/silcclient/command.c.
899 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
901 * Use ++server->cmd_ident when sending commands in server,
902 instead of random number. Affected file silcd/command.c.
904 * Fixed GETKEY command reply to call actually GETKEY pending
905 command callbacks. Affected file silcd/command_reply.c.
907 * A bit stricter check for nicknames. Check for same nickname
908 in NICK command also. Affected file silcd/command.c.
910 * Do not call INFO command everytime client ID changes, only
911 during first connecting. Affected file lib/silcclient/client.c.
913 * Set the new nickname only after successful command reply for
914 NICK command is returned by server. Affected file
915 lib/silcclient/command.c.
917 * Remove nicknames from nicklist during server_signoff notify.
918 Should fix /NAMES bit more. The affected file is
919 irssi/src/silc/core/silc-channels.c.
921 * Added `fingerprint' field to the SilcIDListData in the
922 silcd/idlist.h to hold the fingerprint of the client's
925 Send the fingerprint of the client's public key in WHOIS
928 Affected files silcd/command.c, and silcd/idlist.[ch].
930 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
931 create fingerprint from given data.
933 * Show the fingerprint of the client's public key in WHOIS.
934 Affected files irssi/src/module-formats.[ch] and
935 irssi/src/silc/core/client_ops.c.
937 * Format the multiple same nicknames also during JOIN and
938 NICK_CHANGE notifys. Affected file is
939 lib/silcclient/client_notify.c.
941 * Do not print error on screen for invalid private message
942 payload since it can come if someone is sending private
943 messages with wrong key. Affected file
944 lib/silccore/silcprivate.c.
946 * Fixed multiple concurrent /PING crash. Affected file
947 lib/silcclient/command.c.
949 * Changed the wrong ID encoding. All IP addresses must be
950 in MSB first order in encoded format. They were encoded
951 wrong and was in LSB format. Affected files are
952 silcd/serverid.c, lib/silcutil/silcutil.c.
954 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
956 * Call the `connect' client operation through the scheduler
957 in case of error. Affected file lib/silcclient/client.c.
959 * Call the `failure' client operation even if the error
960 occurred locally during a protocol. Affected file is
961 lib/silcclient/protocol.c.
963 * Added support of sending LIST command to router from normal
964 server. This way normal server can get list of all channels
965 in the network too. Fixed the channel list sending in the
966 server too. Affected files are silcd/command.c, and
967 silcd/command_reply.[ch].
969 * Added silc_server_update_channels_by_server and
970 silc_server_remove_channels_by_server. They are used during
971 disconnection of primary router and in backup router protocol.
972 Affected file silcd/server_util.[ch], silcd/server.c and
973 silcd/server_backup.c.
975 * Fixed channel adding to global list in IDENTIFY command
976 reply in server. Affected file silcd/command_reply.c.
978 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
980 * If the incoming packet type is REKEY or REKEY_DONE process
981 that packet always synchronously. Fixes yet another MAC
982 failed error on slow (dialup) connections. Affected file
983 lib/silcclient/client.c and silcd/server.c.
985 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
987 * Call check_version SKE callback for initiator too. Affected
988 file lib/silcske/silcske.c.
990 * Implemented fix for security hole found in the SKE that was
991 fixed in the specification few days back; the initiator's
992 public key is now added to the HASH value computation.
993 Added backwards support for the old way of doing it too, for
994 old clients and old servers. Affected file is
995 lib/silcske/silcske.c.
997 * Enabled mutual authentication by default in SKE. If initiator
998 is not providing mutual authentication the responder will
999 force it. This will provide the proof of posession of the
1000 private key for responder. The affected files are
1001 lib/silcclient/protocol.c and silcd/protocol.c.
1003 * Do not cache anymore the server's public key during SKE.
1004 We do mutual authentication so the proof of posession of
1005 private key is done, and if the server is authenticated in
1006 conn auth protocol with public key we must have the public
1007 key already. Affected file silcd/protocol.c.
1009 * Added new global debug variable: silc_debug_hexdump. If
1010 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1011 file lib/silcutil/silclog.[ch].
1013 * Fixed compilation warning due to char * -> const char *.
1014 Affected files lib/silcutil/silcnet.h, and
1015 lib/silccore/silcauth.[ch].
1017 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1019 * Fixed CMODE command when new channel key was created. If
1020 the creation failed the old key was removed. Next time giving
1021 same command would crash the server since the old key was
1022 freed already. Affected file silcd/command.c.
1024 * Fixed the silc_server_announce_get_channels to not crash
1025 on reconnect. Affected file silcd/server.c.
1027 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1029 * Added silc_log_set_debug_string function to set a regex
1030 string to match for debug output. Only the function names,
1031 or filenames matching the given debug string is actually
1032 printed. This way it is possible to filter out those debug
1033 strings that user is not interested in.
1035 Fixed a bug in silc_string_regexify.
1037 Affected files lib/silcutil/silclog.[ch], and
1038 lib/silcutil/unix/silcunixutil.c.
1040 * Changed the -d options in both server and Irssi SILC client
1041 to take the debug string as argument. Affected files
1042 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1044 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1046 * Added silc_hash_babbleprint to create a Bubble Babble
1047 Encoded fingerprint. The encoding is developed by Antti
1048 Huima (draft-huima-babble-01.txt), and it creates human
1049 readable strings out of binary data. Affected file
1050 lib/silccrypt/silchash.[ch].
1052 * Print the babble print now in addition of fingerprint as well
1053 in Irssi SILC client. Affected files are
1054 irssi/src/fe-common/silc/module-formats.[ch],
1055 irssi/src/fe-common/silc/core/client_ops.c.
1057 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1059 * Fixed a security problem found in SKE. The initiator's
1060 public key too is now added to the HASH hash value creation
1061 which is signed by the responder to create the SIGN value.
1062 This will prevent anyone in the middle to lie to the responder
1063 about the initiator's public key. If this is done now, the
1064 man in the middle will get caught. Updated the protocol
1067 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1069 * Better installation directory handling. Configure module
1070 paths and other paths automatically to example_silc* files
1071 in doc/. A patch by toma.
1073 * Fixed compiler warning from MPI library, and from SILC RNG.
1076 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1077 It can be configured with ./configure. A patch by toma.
1079 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1081 * Find correct make to use in prepare-clean. A patch by
1082 toma. Affected file prepare-clean.
1084 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1086 * Added irssi variables use_auto_addr, auto_bind_ip,
1087 auto_bind_port and auto_public_ip.
1089 * Changed the interface for silc_client_send_key_agreement
1090 in lib/silcclient/silcapi.h
1094 irssi/src/silc/core/silc-core.c
1096 lib/silcclient/silcapi.h
1097 irssi/src/silc/core/silc-channels.c
1098 lib/silcclient/client_keyagr.c
1101 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1103 * Added silc_pkcs_public_key_compare to compare two
1104 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1106 * Check that the client who set the founder mode on the
1107 channel is the same client that is giving the founder
1108 mode to itself. It is done by comparing the saved public
1109 key (it is saved even in the authentication is passphrase).
1110 Affected file silcd/command.c.
1112 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1114 * Do not process packet for disconnected socket connection.
1115 Affected file lib/silccore/silcpacket.c.
1117 * Process the DISCONNECT packet through scheduler in the
1118 client library. Affected file lib/silcclient/client.c.
1120 * Fixed the silc_client_packet_parse to not to increase
1121 the packet sequence number if the conn->sock and the
1122 current socket connection is not same. This can happen
1123 for example during key agreement when the conn includes
1124 multiple socket connections (listeners). Affected file
1125 lib/silcclient/client.c.
1127 * The sender of the file transfer request now provides also
1128 the pointer (listener) for the key exchange protocol. If
1129 the listener cannot be created then it sends empty key
1130 agreement and lets the receiver provide the listener.
1132 Added `local_ip' and `local_port' arguments to the
1133 silc_client_file_send. If they are provided they are used,
1134 if not then it will attempt to find local IP address, if
1135 not found or bind fails then the remote client will provide
1138 Affected files are lib/silcclient/client_ftp.c and
1139 lib/silcclient/silcapi.h.
1141 * Extended the FILE SEND command to support defining the
1142 local IP and port for key exchange listener. They are
1143 optional. Affected file irssi/src/silc/core/silc-servers.c.
1145 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1147 * Defined to WHOIS command reply the sending of fingerprint
1148 of the client's public key (if the proof of posession of the
1149 corresponding private key is verified by the server).
1150 Updated to the protocol specification.
1152 * Added support of receiving the client's public key's
1153 fingerprint in command reply in client library. Affected
1154 file is lib/silcclient/command_reply.c, and
1155 lib/silcclient/idlist.[ch].
1157 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1214 preserve the WHOWAS info for the client. Affected file
1215 silcd/server_util.c.
1217 * Fixed SERVER_SIGNOFF notify handling in the server. The
1218 server is now able to process incoming SERVER_SIGNOFF notify
1219 for a server that it doesn't even know about. It will remove
1220 the clients provided in the notify. Affected file
1221 silcd/packet_receive.c.
1223 * Check for partial packet in data queue after every packet that
1224 was found from the queue. Return and wait for more data if
1225 there is partial data in queue. Affected file is
1226 lib/silccore/silcpacket.c.
1228 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1239 * Added better monitor of file transfers. It now monitors
1240 key agreement protocol during the file transfer too. Added
1241 error reporting too. Affected files
1242 irssi/src/silc/core/silc-servers.c,
1243 irssi/src/fe-common/silc/module-formats.[ch].
1245 * Wrote a help file for FILE command.
1247 * Added silc_rng_global_get_byte_fast to get not-so-secure
1248 random data as fast as possible. Random data is read from
1249 /dev/urandom if available and from the SILC RNG if not
1250 available. It is used in padding generation. Affected file
1251 lib/silccrypt/silcrng.[ch].
1253 * All packets in client library are now processed synchronously.
1254 Optimized packet processing a lot. Affected file
1255 lib/silcclient/client.c.
1257 * All server connection packets are processing synchronously
1258 now in server, to optimize packet processing. Affected file
1261 * Include files are installed now only in Toolkit distribution
1262 if make install is given. Affected files: all Makefile.am's.
1264 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1266 * Assure that silc_client_notify_by_server_resolve does not
1267 resolve the client information multiple times. If it cannot
1268 be found by the first it cannot be found at all. Affected
1269 file lib/silcclient/client_notify.c.
1271 * Fixed WHOWAS command reply calling. Affected file
1272 lib/silcclient/command_reply.c.
1274 * Removed all references to silc_idlist_get_client from the
1275 Irssi SILC client since that call is internal call used by
1276 the library. The Irssi SILC client will use now client
1277 retrieval functions found in silcapi.h.
1279 * Fixed a bug in resolving nickname info before sending
1280 private message. It used freed memory. Affected file
1281 irssi/src/silc/core/silc-servers.c.
1283 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1285 * Assure my_channels statistics cannot go negative in server.
1286 Affected files silcd/server.c, silcd/server_util.c.

1302 * Added silc_net_localip to return local host's IP address.
1303 Affected file lib/silcutil/silcnet.[ch].
1305 * If key exchange or rekey protocol is active for a connection
1306 parse all packets syncronously since there might be packets
1307 in packet queue that we are not able to process without first
1308 processing packets before them. Affected file silcd/server,
1309 lib/silcclient/client.c.
1311 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1312 whether library should continue processing the packet.
1313 Affected file lib/silccore/silcpacket.h.
1315 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

1357 lib/silcclient/idlist.h.
1359 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1360 is incomplete and is being resolved, it won't be resolved
1363 Make sure also that USERS command reply does not resolve
1364 twice information. Affected file is
1365 lib/silcclient/command_reply.c.
1367 Make sure that silc_client_get_clients_by_list does not
1368 resolve twice same information.
1370 * Check for valid client->id in the silc_server_free_client_data.
1371 Affected file silcd/server.c.
1373 * Fixed /GETKEY nick@server not to crash if the server entry
1374 is not found. Affected file lib/silcclient/command.c.
1376 * Fixed the silc_server_check_cmode_rights to check the
1377 requested modes correctly. Affected file silcd/command.c.
1379 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1381 * Better checks for non-printable chars in nick added.
1382 Affected file silcd/command.c.
1384 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1386 * Call the silc_server_udpate_servers_by_server in the
1387 primary router that comes back online in the backup resuming
1388 protocol. Otherwise it routes packets wrong. Affected file
1389 silcd/server_util.[ch], silcd/server_backup.c.
1391 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1393 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1394 lib/silcutil/silcbuffmt.[ch].
1396 * Redefined the SILC packet header to include the padding
1397 length. Affected file lib/silccore/silcpacket.[ch].
1399 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1400 length for maximum padding up to 128 bytes). Affected
1401 file lib/silccore/silcpacket.h.
1403 * Removed all backwards support for old 0.5.x MAC thingies.
1404 The SILC packet header change makes it impossible to be
1405 backwards compatible.
1407 * Send the ENDING packet with timeout in the backup resuming
1408 protocol. This is to assure that all routers has connected
1409 to the primary router. Affected file silcd/server_backup.c.
1411 * Changed the RNG to take the first IV from random data. It
1412 used to take it from zero actually. Changed the RNG also
1413 to use /dev/urandom during session. /dev/random is used
1414 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1416 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1418 * Changed the SILC packet header to have the first two bytes
1419 (the packet length) encrypted. Affected files aroung the
1420 code tree, lib/silccore/silcpacket.[ch]. Removed the
1421 SilcPacketCheckDecrypt callback. It is not needed anymore
1422 since the silc_packet_receive_process will determine now
1423 whether the packet is normal or special.
1425 * Implemented the unidirectional MAC keys. Affected files
1426 lib/silcske/silcske.c, silcd/protocol.c and
1427 lib/silcclient/protocol.c.
1429 * Implemented the packet sequence number to the MAC computation.
1430 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1431 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1432 lib/silcclient/protocol.c.
1434 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1436 * Allow backup router to announce servers. All servers
1437 announced by backup router are added to the global list
1438 automatically. Update hte server's socket to our primary
1439 router also when backup router announces a server.
1440 Affected file silcd/packet_receive.c.
1442 * Do not update the client->router in the function
1443 silc_server_udpate_clients_by_server if the client is on
1444 global list. We might fail to find any specific server
1445 for locally connected clients and local cell clients. They
1446 should still use the `from' and not `to' as client->router.
1447 This fixes backup router resuming protocol. Affected file
1448 silcd/server_util.c.
1450 * Decrease channel statistics count only if the channel
1451 deletion worked. Affected files are silcd/server.c and
1452 silcd/server_util.c.
1454 * Added silc_server_update_servers_by_server to update origin
1455 of all server entries. Used during backup router protocol.
1456 Affected files silcd/server_util.[ch], silcd/server.c. and
1457 silcd/backup_router.c.
1459 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1460 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1461 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1462 lib/silccrypt/silchmac.c.
1464 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1466 * Assure that router cannot reroute the same channel message
1467 to the sender. Affected file silcd/packet_receive.c.
1469 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1471 * Made better checks that the channel message is not sent
1472 to the router it came from. Affected file is
1473 silcd/packet_send.c. Fixed memory leak too.
1475 * Announce informations for incoming router connection, but
1476 only after checking if it is replaced by backup router.
1477 Affected file silcd/packet_receive.c.
1479 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1481 * Fixed the backup resuming protocol to work in multiple
1482 router environment. Affected file silcd/server_backup.c.
1484 * Route packet only to one router in the function
1485 silc_server_packet_send_to_channel. Affected file is
1486 silcd/packet_send.c.
1488 * Fixed silc_server_send_notify_dest to set the broadcast
1489 flag. Fixed the silc_server_send_notify_topic to actually
1490 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1491 Affected file silcd/packet_send.c.
1493 * Changed the SFTP Filesystem interface. Changed the
1494 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1495 the filesystem operation function. The SilcSFTPFilesystem
1496 is now a context that is allocated by all filesystem allocation
1497 functions and it already includes the operations structure
1498 and filesystem specific context. It is given as argument
1499 now to the silc_sftp_server_start. This made the interface
1500 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1501 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1503 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1505 * Changed the backup router adding and getting interfaces
1506 in the server. The router that will be replaced by the
1507 specified backup router is now sent as argument. Affected
1508 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1511 * Added silc_net_addr2bin_ne to return the binary form of
1512 the IP address in network byte order. Affected files
1513 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1515 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1517 * Check for existing server ID in silc_server_new_server
1518 and in silc_server_connect_to_router_final and remove the
1519 old entry if it exists. Affected file silcd/packet_receive.c,
1522 * Send the channel message always to only one router, either
1523 in upstream or downstream. Affected file is
1524 silcd/packet_send.c.
1526 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1528 * Wrote the definition of the backup resuming protocol to the
1529 protocol specification.
1531 * Removed one redundant channel key generation from normal
1532 server during joining procedure. Removed one redundant
1533 channel key sending from server to router during joining
1534 procedure. Affected file silcd/command.c.
1536 * Made minor bugfixes to the backup router resuming protocol.
1537 Affected file silcd/server_backup.c, server.c.
1539 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1541 * Added --disable-asm configuration option. Affected files
1542 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1545 * Implemented the backup resuming protocol that is used to
1546 resume the primary router position in the cell after the
1547 primary router comes back online. Affected files
1548 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1549 and silcd/server_util.[ch].
1551 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1553 * Sleep two (2) seconds after sending QUIT command to server.
1554 Affected file lib/silcclient/command.c.
1556 * Assure that if outgoing data buffer is pending do not force
1557 send any data. Affected file silcd/packet_send.c.
1559 * Assure that if outgoing data buffer is pending do not force
1560 send any data. Affected file lib/silcclient/client.c.
1562 * Implemented the backup router support when the primary router
1563 goes down. The servers and routers can now use the backup
1564 router as new primary router without loosing connectivity.
1566 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1568 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1569 in the server to indicate disabled entry. All data read
1570 from the connection will be ignored and no data is sent
1571 for entry that is disabled. Affected files are
1572 silcd/idlist.h, silcd/server.c.
1574 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1576 * Created SFTP client and server test programs in the
1577 lib/silcsftp/tests directory.
1579 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1581 * Implemented memory filesystem (virtual filesystem) for
1582 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1585 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1587 * Implemented the SFTP (SSH File Transfer Protocol) to the
1588 lib/silcsftp. It includes SFTP client and SFTP server
1591 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1593 * Moved lib/silccore/silcprotocol.[ch] to the
1594 lib/silcutil library.
1596 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1597 take variable argument list pointer as argument. Affected
1598 file lib/silcutil/silcbuffmt.[ch].
1600 * Added silc_buffer_set function that is used to set data
1601 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1602 Affected file lib/silcutil/silcbuffer.h.
1604 * Changed various routines in the core library to use the new
1605 silc_buffer_set instead of allocating new buffer only for
1608 * Added 64-bit value formatting and unformatting support to the
1609 silc_buffer_[un]format routines. Affected file is
1610 lib/silcutil/silcbuffmt.[ch].
1612 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1613 to includes/bitmove.h.
1615 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1617 * Fixed channel user mode saving in client library. Affected
1618 file lib/silcclient/command[_reply].c.
1620 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1622 * Defined the file transfer to the SILC Protocol. Added
1623 new packet type SILC_PACKET_FTP and defined File Transfer
1624 Payload. The mandatory file transfer protocol is SFTP
1625 (SSH File Transfer Protocol). Affected file in addition
1626 of the internet draft is lib/silccore/silcpacket.h.
1628 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1629 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1630 is used as part of backup router protocol when the primary
1631 router of the cell is back online and wishes to resume
1632 the position as primary router.
1634 * Redefined the MAC generation keys in the protocol. The
1635 same key is not used anymore in both direction. Both
1636 direction will now use different keys for sending and
1637 receiving. This fixes a potential security flaw. This
1638 change causes incompatibilities in the protocol.
1640 * Redefined also the MAC computation from the packet.
1641 An packet sequence number is now added to the MAC
1642 computation. This prevents possible replay attacks against
1643 the protocol. This change too causes incompatibilities
1646 Added `sequence' field to the SilcPacketContext to hold
1647 the current sequence number for the packet.
1649 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1651 * Added `created' field to the SilcIDListData in the file
1652 silcd/idlist.h to indicate the time when the entry was
1655 * Added `created' field to the SilcChannelEntry too. Affected
1656 file silcd/idlist.h.
1658 * Added `creation_time' aguments to all the announcement functions
1659 in the server. If it is provided then only the entries that
1660 was created after the provided time frame are actually
1661 announced. Affected file silcd/server.[ch].
1663 * The protocol says that the Channel ID's IP address must be
1664 based on the router's IP address. Added check for this in
1665 the silc_server_new_channel when processing incoming New Channel
1666 Payload. Affected file silcd/packet_receive.c.
1668 * Print out the correct version with --version in SILC client.
1669 Affected file irssi/src/silc/core/silc-core.c.
1671 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1673 * Fixed WHOWAS command to check for completnes of the client
1674 entry always, not just when the command is coming from client.
1675 Affected file silcd/command.c.
1677 * Added new function silc_server_packet_queue_purge to purge the
1678 outgoing data queue to the network. After the function returns
1679 it is guaranteed that the outgoing packet queue is empty.
1680 Affected file silcd/packet_send.[ch].
1682 * Purge the outgoing packet queue in the rekey protocol's final
1683 callback to assure that all rekey packets go to the network
1684 before quitting the protocol. Affected file silcd/server.c.
1686 * Added silc_client_packet_queue_parse as similar function as
1687 in server to the client library. The affected file is
1688 lib/silcclient/client.c.
1690 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1692 * Splitted silcd/server.c and created silcd/server_util.[ch]
1693 for utility functions.
1695 * Added new socket flag SILC_SF_DISABLED to indicate that the
1696 connection is open but nothing can be sent to or received from
1697 the connection. Affected file lib/silcutil/silsockconn.[ch].
1698 The checking for disabled socket is checked in the low level
1699 silc_socket_write and silc_socket_read functions.
1701 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1703 * Allow only nicknames and channel names that fits into the
1704 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1706 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1708 * When processing JOIN command reply in server check that if
1709 the channel exists in our global list we'll move it the local
1710 list. Affected file silcd/command_reply.c.
1712 * Fixed the check whether client is joined on the channel already
1713 in JOIN command. Affected file lib/silcclient/command.c.
1715 * Fixed the JOIN command reply to check whether the channel
1716 already exists. Affected file lib/silcclient/command_reply.c.
1718 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1720 * Added silc_ske_status_string to map the SKE error numbers
1721 to readable strings. The affected files are
1722 lib/silcske/silcske[_status].[ch].
1724 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1726 * Do not show the private channels on the WHOIS channel list
1727 as it is not allowed by the protocol. The affected file is
1730 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1732 * Assure that the packet length digged from the actual packet
1733 is something sensible in the silc_packet_decrypt_rest_special
1734 in lib/silccrypt/silcpacket.c.
1736 * Free and NULL the allocated pointer in silc_hmac_alloc if
1737 the HMAC allocation fails. The affected file is
1738 lib/silccrypt/silchmac.c.
1740 * Print the selected security properties to the log files in
1741 the server. Affected file silcd/protocol.c.
1743 * Add SKE's reference counter even if calling the completion
1744 callback manually. Otherwise it goes negative, although it
1745 does not cause any problems. The affected file is
1746 lib/silcske/silcske.c.
1748 * Remove the client entry with short timeout after giving the
1749 KILL command. Affected file lib/silcclient/command.c.
1751 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1752 case all found clients are already disconnected (WHOWAS would
1753 found them) in the server. Affected file silcd/command.c.
1755 * Update the last_receive (time of last data received) to be
1756 updated only when received private or channel message so that
1757 the idle time showed in WHOIS makes more sense.
1759 * Added boolean field `valid' in to the SilcClientEntry in the
1760 client library to indicate whether the entry is valid or not.
1761 This fixes the nickname change bug on channel when changing
1762 the nickname to be same than the old (like nick to Nick) the
1763 nickname formatter doesn't set the new nick anymore to Nick@host.
1764 Affected file lib/silcclient/idlist.[ch].
1766 * Now actually fixed the nickname changing on disconnection.
1767 Added new function silc_change_nick to the Irssi SILC Client.
1768 Affected file irssi/src/silc/core/client_ops.c,
1769 irssi/src/silc/core/silc-nicklist.[ch].
1771 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1773 * Check that the public key exists in the GETKEY command before
1774 trying to encode it. Affected file silcd/command.c.
1776 * Print some notifications on received public keys with GETKEY
1777 command in the Irssi SILC Client. Affected files are
1778 irssi/src/fe-common/silc/module-formats.[ch],
1779 irssi/src/silc/core/client_ops.c.
1781 * Use IDENTIFY command to resolve the server information in the
1782 GETKEY command instead of INFO command. Affected file
1783 lib/silcclient/command.c.
1785 * All command reply functions in the client library now calls
1786 the pending command reply callbacks even if an error has
1787 occurred. The server has done this a long time and now it was
1788 time to move the client library to this as well. Now all
1789 errors can be delivered back to the pending command reply
1790 callbacks if necessary. Affected files are
1791 lib/silcclient/command[_reply].[ch].
1793 * Change the nickname on disconnection back to the username
1794 because in reconnect the server will enforce it to it anyway.
1795 Affected file irssi/src/silc/core/silc-servers.c.
1797 * Fixed a config file parsing bug in the Irssi SILC client.
1798 Affected file irssi/src/silc/core/clientconfig.c.
1800 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1802 * When printing the channel mode on JOIN, verify that the
1803 channel key and channel's HMAC are valid. Affected file
1804 irssi/src/silc/core/client_ops.c.
1806 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1808 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1809 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1810 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1812 * Removed channel key rekey task deleting from the function
1813 silc_server_save_channel_key. Affected file silcd/server.c.
1814 Added explicit timeout task context instead that is used to
1815 delete the task if we are registering a new task before the
1816 new task has elapsed.
1818 * When channel key rekey occurs the client library now saves
1819 the old channel key for a short period of time (10 seconds) and
1820 is able to use it in case some is still sending channel
1821 messages encrypted with the old key after the rekey. Affected
1822 file lib/silcclient/[idlist.h|client_channel.c].
1824 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1826 * Added check to the silc_server_new_id_real to not accept
1827 new ID if it is the sender's own ID. Affected file is
1828 silcd/packet_receive.c.
1830 * Assure that we do not announce ourself or the one we've
1831 sending our announcements when we're router and are announcing
1832 servers to our primary router. Affected file silcd/server.c.
1834 * Fixed silc_server_command_identify_check_client to assemble
1835 correct WHOIS packet. It send corrupted WHOIS packet and
1836 caused problem with router to router connections. Affected
1837 file silcd/command.c.
1839 Fixed also silc_server_command_whois_check the same way
1840 as for the IDENTIFY command.
1842 * Added new SilcIDListStatus to the server in the SilcIDListData
1843 structure. The status now includes the current status of
1844 the entry (like registered, resolved etc.). Affected file
1845 silcd/idlist.[ch]. Defined a bunch of different status types
1846 as well. This replaced the old boolean registered field as well.
1848 Added resolve_cmd_ident field to the SilcClientEntry structure
1849 too so that if the entry is for example being resolved so
1850 another command may attach to the same pending command reply
1851 without requiring to resolve the same entry again. This concept
1852 should optimize the WHOIS and the IDENTIFY resolving under
1853 heavy load by taking away unnecessary resolving for entries
1854 that are being resolved already.
1856 Added support for adding multiple pending commands for one
1857 command idenfier. Affected file silcd/command[_reply].[ch].
1859 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1860 before deleting the data. Otherwise the hash table will have
1861 freed data in comparison functions. Affected file is
1862 silcd/command_reply.c.
1864 * Fixed silc_idlist_replace_client_id to add the new entry to
1865 the cache with NULL nickname. Otherwise there will be invalid
1866 memory as the nickname after the nickname is freed. Affected
1867 file silcd/packet_receive.c.
1869 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1870 saved into wrong slots because the previous number of entries
1871 was not taken into account. Affected file silcd/idlist.c.
1872 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1874 * If we are router and we receive JOIN notify to a channel that
1875 does not have any users then notified client is marked as the
1876 channel founder, as it is it. The affected file is
1877 silcd/packet_receive.c
1879 * Added to the extended hash table API's table_del_*ext functions
1880 the destructor as argument too, so that the caller can decide
1881 which destructor to use or whether to use destructor at all.
1882 Affected file lib/silcutil/silchashtable.[ch].
1884 * Fixed ID Cache purging. It actually deleted the entries from
1885 the hash table after the data was freed. The hash table ended
1886 up comparing freed memory. The affected file is
1887 lib/silccore/silcidcache.c.
1889 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1891 * Fixed Irssi SILC client's KILL command's HELP syntax.
1893 * The USERS command now resolves the detailed user information
1894 if the userinfo field is missing. Affected file is
1895 lib/silcclient/command_reply.c.
1897 * Do not print error in silc_file_read if the read file does
1898 not exist. Just silently return NULL. Affected file is
1899 lib/silcutil/silcutil.c.
1901 * Fixed the silc_log_output to not wine about NULL filename
1902 and to not create some bogus " " filename. Affected file is
1903 lib/silcutil/silclog.c.
1905 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1907 * Fixed various printing bugs on the user interface in the
1908 Irssi SILC Client. Minor changes that were forgotten from
1911 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1913 * Fixed the configure.in.pre and the compilation and distribution
1914 environment to support the new autoconf 2.52. That version is
1915 now required to compile the CVS trunk.
1917 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1919 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1920 to generally parse user@fqdn format strings. Affected file
1921 lib/silcutil/silcutil.c.
1923 * Added nickname_format and nickname_force_format fields to the
1924 SilcClientParams structure. The first one defines the format
1925 for the nicknames that the library will enforce if the receives
1926 multiple same nicknames. The second one is boolean value and
1927 can be used to force the library to always enforce the format
1928 to the nicknames regardles whether there are multiple nicknames
1929 or not. This configurable formatting was employed to flexibly
1930 support accessing multiple nicknames from the user interface.
1931 The userinterface can now set the nicknames to what ever format
1932 they prefer. Affected file lib/silcclient/silcapi.h.
1934 Added function silc_client_nickname_format to the file
1935 lib/silcclient/idlist.c. It performs the nickname formatting.
1937 Added new field `hostname´ to the SilcClientEntry context.
1938 It holds the hostname of the client. Affected file is
1939 lib/silcclient/idlist.h.
1941 * Irssi SILC Client sets the nicknames in nick@hostn format.
1942 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1943 irssi/src/silc/core/silc-core.c.
1945 The WHOIS printing now also shows both the real nickname and
1946 the formatted nickname so that user knows how to access the
1947 user if there are multiple same nicknames cached. Affected
1948 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1949 printing formatting too to take the hostname now as a separate
1950 argument. The Affected file is
1951 irssi/src/fe-common/silc/modules-formats.[ch].
1953 * Changed the silc_client_get_clients_local to accept the formatted
1954 nickname as argument. It accepts the real nickname too but the
1955 formatted nickname can be used to find the true entry from
1956 multiple entries. Affected file lib/silcclient/silcapi.h and
1957 lib/silcclient/idlist.c.
1959 * Added nickname_format_parse field to the SilcClientParams.
1960 It is a callback function provided by the application to parse
1961 the nickname out of the formatted nickname string. The library
1962 calls it to get the nickname from the formatted string. Since
1963 the application generally knows better the format of the nickname
1964 string it parses it instead of the library, even though library
1965 encodes the formatted string. If the callback function is not
1966 provided then the library will use the string as is. The
1967 affected file is lib/silcclient/silcapi.h.
1969 * All the nickname strings passed to the client library in
1970 commands are now expected to be formatted nickname strings.
1971 If the command does not support the formatted nickname string
1972 it will assume that the sent string is the actual nickname.
1973 Affected file lib/silcclient/command.c.
1975 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1977 * Added public key authentication support to OPER and SILCOPER
1978 commands in the client library. Affected file is
1979 lib/silcclient/command.c.
1981 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1983 * Changed the get_auth_methdod client operation to be asynchronous.
1984 It can be async if the application resolves the authentication
1985 method from the server during the negotiation. Added new
1986 SilcGetAuthMeth completion callback that the application will
1987 call after resolving the authentication method.
1989 Added function silc_client_request_authentication_method that
1990 the application can use to resolve the authentication method
1991 from the server. Added also SilcConnectionAuthRequest callback
1992 that the library will call after the server has replied. The
1993 application can call this function if it does not know the
1994 current authentication method.
1996 Affected files are lib/silcclient/client.c and
1997 lib/silcclient/silcapi.h.
1999 * The Irssi SILC client now automatically resolves the authentication
2000 method incase any configuration information is not present (and
2001 currently there never is). The affected file is
2002 irssi/src/silc/core/client_ops.c.
2004 * Fixed public key authentication from the client library.
2005 Affected file lib/silcclient/protocol.c. Changed also the
2006 protocol specification about the public key authentication in
2007 the connection authentication protocol. The actual data to be
2008 signed is now computed with a hash function before signing.
2010 * Fixed the public key authentication from the server as well.
2011 Affected file silcd/protocol.c.
2013 * Removed the mlock()'s from the memory allocation routines.
2014 Affected file lib/silcutil/silcmemory.c. The ./configure does
2015 not check anymore for the mlock(). Affected file is
2018 * Fixed USERS command in server to allow the execution of the
2019 command for private and secret channels if the client sending
2020 the command is on the channel. Affected file silcd/command.c.
2022 * Fixed silc_client_get_clients_local to return the clients
2023 count correctly. It could return wrong value. Affected file
2024 lib/silcclient/idlist.c.
2026 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2028 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2029 types. The assembler optimizations seemed not to like 64-bit
2030 data types. The assmebler optimizations thus are now enabled
2031 also for BSD systems as opposed to only enable them for Linux.
2033 * Do not check for threads at all on BSD systems. Affected
2034 file configure.in.pre.
2036 * Removed -n and -h options from the Irssi SILC Client since
2037 they are not used in silc.
2039 * Fixed the prime generation to assure that the first digit
2040 of the generated random number is not zero since our conversion
2041 routines does not like number strings that starts with zero
2042 digit. If zero digit is seen the random number is regenerated.
2043 This caused some corrupted RSA keys when the zero first digit
2044 was met. Affected file lib/silcmath/silcprimegen.c.
2046 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2048 * Fixed WIN32 configuration in the ./configure script.
2049 Fixed to include xti.h on environments that has it.
2050 Patches by Carsten Ilchmann and andrew.
2052 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2054 * Changed the silc_id_create_client_id to be collision
2055 resistant. It is now assured that there cannot be created
2056 two same client ID's. I suspect that some weird bugs in
2057 the server were actually caused by duplicate Client IDs.
2058 Affected file silcd/serverid.[ch]. A router receiving
2059 new ID now also assures and informs the sending server
2060 if the ID caused collision.
2062 * Changed the silc_id_create_channel_id to also assure that
2063 there are no collisions.
2065 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2067 * Statement about ignoring the Mutual Authentication flag when
2068 performing rekey with PFS was a bit misleading. It is ignored
2069 if it was set in the initial negotiation, it cannot be even
2070 set in the rekey. Fixed in the ke-auth draft. Started the
2071 new versions of the protocol drafts in the doc/.
2073 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2075 * Fixed a bug in silc_client_command_identify_save when saving
2076 new channel information. The channel name was no duplicated
2077 and caused crash on exit. Affected file is
2078 lib/silcclient/command_reply.c.
2080 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2082 * Fixed the getkey command handling in the server. Send just
2083 empty OK reply to the sender if the key could not be fetched
2084 (but everything else was ok, like the key just was not available).
2085 Changed the public key parameter to optional in the protocol
2086 specs so that empty OK reply can be sent. Affected file
2089 Added a message to Irssi SILC client to tell to user if the
2090 server did not return a public key.
2092 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2094 * Fixed a channel key regeneration bug. It registered new
2095 timeout tasks exponentially until all system resources were
2096 used. Affected file silcd/server.c.
2098 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2100 * Added the SILC Document generator to the scripts/silcdoc.
2101 It can be used to generate the Toolkit Reference Manual out
2102 of the source tree. Internally it will also use the RoboDoc
2103 generator now imported in util/robodoc.
2105 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2107 * Added couple of return's in rekey protocol if error orccurred
2108 during the protocol. The execution must be terminated.
2109 Affected file silcd/protocol.c. Also, terminate the protocol
2110 always with timeout.
2112 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2114 * The client's Client ID was created initally from the wrong
2115 nickname (it could have been in format nick@host) in the
2116 silc_server_new_client. Affected file silcd/packet_receive.c
2118 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2120 * Added some SILC_LOG_ERROR's to various error conditions
2121 if client could not be added to ID cache. Affected files
2122 silcd/packet_receive.c and silcd/server.c.
2124 * When client's sock->user_data is freed, NULL also the
2125 client->router and client->connection pointers. Added check
2126 for these pointers being NULL to various places around the
2127 code. Affected file silcd/server.c.
2129 * Added client->data.registered == TRUE checks to various
2130 places around the code to assure that unregistered client's
2131 are not handled when it is not allowed. Affected file
2134 * Added `bool registered' fields to all
2135 silc_idlist_[server|client]_get_* routines to indicate whether
2136 the fetched client needs to be registered or not. Affected
2137 file silcd/idlist.[ch].
2139 * Add your own entry as registered to the ID cache in the
2140 server. Affected file server.c.
2142 * Fixed a bug in silc_server_new_server. The SilcServer was
2143 set as the new server's context instead of SilcServerEntry.
2144 This naturally caused some weird bugs.
2146 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2148 * Do not delete the channel rekey task when adding it
2149 for in silc_server_create_channel_key.
2151 * Changed the silc_server_create_channel_key to return
2152 TRUE or FALSE to indicate the success of the channel key
2155 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2157 * Fixed MSVC++ project files and added missing files to

2162 * Do not add TCP_NODELAY flag if the operating system
2163 does not have it defined. Affected files are
2164 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2166 * Fixed buffer overflow from Irssi SILC Client. Affected
2167 file irssi/src/fe-common/core/themes.c.
2169 * Fixed double free in client library in the file
2170 lib/silcclient/client.c when disconnecting from server.
2172 * Applied double free patch from cras to Irssi SILC client.
2173 Affected files irssi/src/core/[modules/expandos].c
2175 * Fixed the disconnection handling to Irssi SILC Client.
2176 The application must call silc_client_close_connection
2177 in ops->connect client operation in case of failure of
2178 the connection. Affected file is
2179 irssi/src/silc/core/client_ops.c.
2181 * Do not set sock->protocol to NULL in the function
2182 silc_client_close_connection after executing the protocol's
2183 final callback since the sock might not be valid anymore.
2184 Affected file lib/silcclient/client.c.
2186 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2188 * Do not enable SILC_THREADS if the linking with libpthread
2189 did not happen. Affected file configure.in.pre.
2191 * Added notion to protocol specification that server must
2192 verify the sent authentication payload with CMODE when
2193 setting the channel founder key. Implemented it to the
2194 server. Affected file silcd/command.c.
2196 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2198 * Added _EXTRA_DIST SILC distribution variable to the
2199 distributions file. It is used to conditionally add extra
2200 files or directories to the specific distribution. Affected
2201 files ./prepare, Makefile.am.pre and distributions.

2206 * Added README.WIN32 for instructions to compile the Toolkit
2209 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2211 * Fixed a double free in disconnection in the server. Affected
2212 file is silcd/server.c.
2214 * Fixed the lib/silcske/groups.c to work now also with GMP
2215 MP library. The string conversion did not work when using
2216 specific base and the base is indicated in the string as well.
2218 * Created win32/ directory which now includes MSVC++ specific
2219 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2220 It will appear only in the toolkit distribution
2222 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2224 * Changed the key material distribution function in case when
2225 the hash output is too short. The data is now concatenated
2226 a bit differently than it used to. Made the change to the
2227 SKE protocol specification.
2229 * Added better GMP detection to configure.in.pre. A patch
2232 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2234 * Fixed a minor bug in SKE that might cause some problem on
2235 some platforms. Affected file lib/silcske/silcske.c.
2237 * Added the cookie checking for initiator in the SKE. It checks
2238 that the responder returns the sent cookie unmodified. The
2239 affected file is lib/silcske/silcske.c. Added new SKE
2240 error type INVALID_COOKIE that can be sent during the
2241 negotiation. Fixed some memory leaks as well.
2243 * Added the "invalid cookie" error message to Irssi SILC client's
2246 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2248 * Added `task_max' field to the SilcClientParams to indicate
2249 the maximum tasks the scheduler can handle. If set to zero,
2250 default values are used. Affected file lib/silcclient/silcapi.h.
2252 * Fixed memory leaks in silc_client_close_connection. Affected
2253 file lib/silcclient/client.c.
2255 * Added silc_client_del_client_entry to client library to free
2256 all memory of given client entry. Affected file is
2257 lib/silcclient/idlist.[ch].
2259 * Added new functions silc_client_del_channel and
2260 silc_client_del_server to delete channel and server entries.
2261 Affected file lib/silcclient/[silcapi.h/idlist.c].
2263 * Removed silc_client_del_client_by_id from silcapi.h.
2265 * Fixed the INFO command to return the server's own info
2266 correctly when querying by Server ID. Affected file is
2269 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2271 * Removed the non-blocking settings in WIN32 code in the
2272 silc_sock_[read/write] and added SleepEx instead. Affected
2273 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2274 of input data is now checked with FIONREAD and ioctlsocket.
2276 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2278 * Call silc_schedule_task_del_by_context in the
2279 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2280 Affected file lib/silccore/silcprotocol.c.
2282 * Call silc_protocol_cancel for active protocols in the
2283 silc_server_close_connection if the funtion
2284 silc_server_free_sock_user_data has not been called.
2285 Affected file silcd/server.c.
2287 * Generic tasks cannot be deleted using the del_by_fd
2288 task deleting function since generic tasks does not match
2289 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2291 * Added a notion to SILCOPER help file that the SILCOPER works
2292 only on router server, not on normal server.
2294 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2296 * Added for WIN32 support for the new scheduler as well.
2297 Affected file lib/silcutil/win32/silcwin32schedule.c.
2299 * Fixed the SHA1 implementation to work on various platforms.
2301 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2303 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2304 API. It is part of the scheduler now. Everything else is
2305 as previously but some functions has changed their names.
2306 Checkout the lib/silcutil/silcschedule.h for the interface.
2307 Updated all applications to use the new interface. Affected
2308 files are lib/silcutil/silcschedule.[ch].
2310 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2312 * Found a bug in the SKE implementation. The HASH value,
2313 specified by the protocol, was not computed correctly. The
2314 public key of the responder was not added to the computation
2315 even though it is mandatory. Affected file lib/silcske/silcske.c.
2316 This unfortunately causes incompatibilities with older
2317 clients and servers.
2319 * Added WIN32 specific network init and uninit functions:
2320 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2321 the Winsock2. Affected file lib/silcutil/silcnet.h and
2322 lib/silcutil/win32/silcwin32net.c.
2324 * Set the socket always to nonblocking mode on WIN32 after
2325 reading data or writing data. Affected file is
2326 lib/silcutil/win32/silcwin32sockconn.c.
2328 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2330 * Fixed various compilation problems under WIN32. Affected
2331 files lib/silcutil/win32/silcwin32thread.c and
2332 lib/silcutil/win32/silcwin32schedule.c.
2334 * Removed all _internal.h #includes from public header
2335 files. Internal headers must never be included from
2338 Removed also the lib/silcske/payload_internal.h file.
2340 * All include files that may be needed (public and some others
2341 included by the public headers) by application developers are
2342 now copied to the ./includes directory. It does not copy any
2343 internal headers. Affected file Makefile.defines.pre and all
2344 Makefile.am's under lib/ and subdirs.
2346 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2348 * Do not change the ~/.silc directory's permissions automatically.
2349 Affected file irssi/src/silc/core/clientutil.c.
2351 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2353 * Do not cancel the protocol in silc_server_close_connection
2354 it might cause recursion. Now cancelled in the function
2355 silc_server_free_sock_user_data. Affected file silcd/server.c.
2357 * Fixed the silc_server_remove_clients_by_server to regenerate
2358 the channel keys correctly finally. Added also new function
2359 silc_server_remove_clients_channels to actually do it.
2360 Affected file silcd/server.c.
2362 * Fixed the silc_server_new_channel to not crash by giving
2363 wrong router to the new channel. Affected file is
2364 silcd/packet_receive.c.
2366 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2368 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2369 which is given as argument to the silc_client_alloc now.
2370 It can be used to configure the client and set various parameters
2371 that affect the function of the client.
2373 * The USERS command in server did not check whether the channel
2374 is private or secret. Affected file silcd/command.c.
2376 * Added new argument to the USERS command in protocol specification.
2377 The USERS command now can take the channel name as argument
2378 as well. Added support for this in client and server and
2379 updated the protocol specs.
2381 * Completed the GETKEY command in client. It can be now used
2382 to fetch also servers public key not only some clients.
2383 Affected files lib/silcclient/command[_reply].c.
2385 * Added silc_client_get_server to return server entry by the
2386 server name. Affected files lib/silcclient/silcapi.h and
2389 * Redefined the IDENTIFY command in protocol specification to be
2390 more generic. It now can be used to query information about
2391 any entity in the SILC Network, including clients, servers and
2392 channels. The query may be based either the entity's name
2393 or the ID. Added support for this in both client and server.
2395 Affected files silcd/command.c and lib/silcclient/command.c
2396 and command_reply.c.
2398 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2399 the _from_client and _from_server functions. Affected file
2402 * Added silc_client_get_channel_by_id_resolve to the file
2403 lib/silcclient/silcapi.h to resolve channel information by
2404 its ID. Added also silc_client_get_channel_by_id that
2405 does not resolve it from the server.
2407 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2409 * Added SilcServerEntry context into the client library
2410 to represent one server. The INFO command now allocates
2411 these to save the resolved server info. For now on the
2412 client library will also keep information about servers,
2413 connected and resolved with INFO.
2415 The INFO command now allocates the SilcServerEntry context
2416 and saves the server info there. The COMMAND_REPLY in
2417 the INFO now returns the parameters to application in
2418 same order as defined in the protocol specification.
2420 The entries are cached in the client->server_cache.
2422 * The INFO command is now issued after received the Client ID
2423 from the server. Affected file lib/silcclient/client.c.
2425 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2426 to the application as the mode changer might be server.
2427 It is guaranteed that NULL is not returned anymore to the
2428 application. Affected file lib/silcclient/client_notify.c.
2430 The ID Type is now also passed to the application so that
2431 it can check whether the returned entry is SilcClientEntry
2434 Added new function silc_client_get_server_by_id to return
2435 the server entry by ID. Affected files are the
2436 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2438 * Do not create the channel in the Irssi SILC Client when issuing
2439 the JOIN command but when received the sucessful JOIN command
2440 reply. Otherwise the channel might get created even though we
2441 could not join it. The Affected file is
2442 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2444 * Fixed a channel joining bug in router. The router must also
2445 check the channel modes, invite and ban lists etc. when serving
2446 the JOIN command sent by normal server. Affected file is
2447 silcd/command.c. The router now resolves the client's
2448 information from the server who sent the JOIN command if it
2449 does not know it, and processes the JOIN command only after
2452 * Changed the SilcCommandCb to take new argument; void *context2.
2453 Affected file lib/silccore/silccommand.h
2455 The second argument in the command callbacks in the server now
2456 includes the SilcServerCommandReplyContext if the command was
2457 called as pending command callback from the command reply.
2458 Otherwise it is NULL. When called as pending the status of the
2459 command reply will be checked and if it was erronous the
2460 error will be sent to the original sender of the command.
2461 This way the client always receives the error messages even
2462 though the server was actually the one who received the error
2463 when it resent the command to router, for example. Affected
2464 files silcd/command[_reply].[ch].
2466 * Fixed sending WHOWAS command's error message to client if
2467 the requested client could not be found. It was missing.
2470 * Changed the CMODE and CUMODE commands reply arguments in the
2471 protocol specification. The Channel ID is now sent in both
2472 of the commands to identify the channel. Implemented this
2473 new feature to the client and server. Affected files
2474 lib/silcclient/command_reply.c and silcd/command.c.
2476 * Made better checks for invite and ban lists in the JOIN
2477 command in server. Affected file silcd/command.c.
2479 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2481 * The server now performs the incoming host IP/DNS lookup
2482 using the silc_socket_host_lookup and thus does not block
2483 the server anymore. Affected file silcd/server.c.
2485 * Completed the multi-thread support for SILC Scheduler in
2486 the lib/silcutil/silcschedule.c.
2488 * Fixed the configure.in.pre to detect the pthread correctly
2491 * Fixed a deadlock in silc_task_queue_wakeup in the file
2492 lib/silcutil/silctask.c.
2494 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2496 * Added new function silc_schedule_wakeup that is used in
2497 multi-threaded environment to wakeup the main thread's
2498 schduler. It needs to be used when a thread adds a new task
2499 or removes a task from task queues. After waking up, the
2500 scheduler will detect the task queue changes. If threads
2501 support is not compiled in this function has no effect.
2502 Implemented the wakeup mechanism to both Unix and WIN32
2503 systems. Affected files are lib/silcutil/silcschedule.[ch],
2504 lib/silcutil/unix/silcunixschedule.c and the
2505 lib/silcutil/win32/silcwin32schedule.c.
2507 * Added new function silc_task_queue_wakeup to wakeup the
2508 scheduler by the specified task queue. Affected file
2509 lib/silcutil/silctask.[ch].
2511 * The silc_socket_host_lookup_start now wakes up the scheduler
2512 after adding the timeout task. Affected file is
2513 lib/silcutil/silcsockconn.c.
2515 * The silc_socket_host_lookup is synchronous now if the threads
2516 support is not compiled in. However, the callback is still
2517 called asyncronously through the scheduler, anyway. Affected
2518 file lib/silcutil/silcsockconn.c.
2520 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2522 * Added new function silc_socket_host_lookup to perform
2523 asynchronous IP and FQDN lookups for the socket connection.
2524 Affected files lib/silcutil/silcsockconn.[ch].
2526 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2528 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2529 that may or may not compile the mutex support in.
2531 Changed the silc_mutex_alloc interface. It allocates the
2532 mutex now to the sent pointer and returns TRUE or FALSE.
2534 Affected file lib/silcutil/silcmutex.h.
2536 * Wrote the SILC Task Queue interface to support multi-threads.
2537 Affected file lib/silcutil/silctask.[ch].
2539 * Wrote the SILC Scheduler to support multi-threads. Affected
2540 file lib/silcutil/silcschedule.c.
2542 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2544 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2545 in lib/silcutil/win32/.
2547 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2549 * Defined SILC Mutex API and SILC Thread API and implemented
2550 them for Unix. Affected files are
2551 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2552 lib/silcutil/unix/silcunixmutex.c and
2553 lib/silcutil/unix/silcunixthread.c.
2555 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2557 * Fixed the silc_server_remove_clients_by_server's channel
2558 key re-generation. The hash table handling was incorrect
2559 and would not work with many channels. Affected file is
2562 * Fixed some memory leaks around the server code.
2564 * Rewrote the silc_server_get_users_on_channel to support IPv6
2565 based Client ID's. Affected file silcd/server.c.
2567 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2568 specification. However, a separate document must be written
2569 to define the detailed signing procedure and the payload
2570 associated with the flag. Defined the flag to the
2571 lib/silccore/silcchannel.h as well.
2573 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2575 * Changed the dynamic tables to static size tables in the
2576 lib/silccrypt/silchmac.c.
2578 * Removed GCC dependencies from the code. A patch by cras.
2580 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2582 * Do not show the error "Error receiving packet bla bla"
2583 in server if it really was not an error (-2 means that reading
2584 is pending). Affected file silcd/server.c.
2586 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2588 * Fixed a possible crash in silc_server_remove_clients_by_server
2589 in silcd/server.c. Fixed there also some memory leaks.
2591 * Fixed the silc_idlist_replace_client_id. It could replace
2592 wrong key in the hash table. Affected file silcd/idlist.c.
2594 * Do not check whether there are global users on the channel
2595 if the channel->global_users is FALSE. Affected functions
2596 silc_server_remove_from_one_channel and
2597 silc_server_remove_from_channels in silcd/server.c. Also,
2598 do not check if the removed client is local as we can be
2599 sure that global client was not removed from the channel
2600 and checking for global users is not needed.
2602 * The silc_server_remove_clients_by_server now re-generates
2603 the channel keys correctly for those channels that had
2604 clients removed from them. Affected file silcd/server.c.
2606 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2608 * Found the reason of random crashes in the server. We weren't
2609 ignoring the SIGPIPE signal (which can be sent in write())
2610 and it crashed the server. Affected file silcd/silcd.c.
2612 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2614 * Assure that sock->user_data is not NULL in the function
2615 silc_server_packet_send in silcd/packet_send.c.
2617 * Disconnect the remote connection if it could not be added
2618 to any ID lists in the server. The affected file is
2621 * Check in silc_server_packet_send[_real/dest] that the
2622 socket is not disconnecting and ignore the data if it is.
2623 Affected file silcd/packet_send.c.
2625 * Define inline to __inline on native WIN32 compilation.
2626 Affected file includes/silcwin32.h.
2628 * Added some explicit type casts for inline code since MSVC
2629 require them. Affected files lib/silcutil/silcbuffer.h,
2630 lib/trq/silcdlist.h and lib/trq/silclist.h.
2632 * Print warning in log files from now on if the packet
2633 decryption fails. Affected file silcd/server.c.
2635 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2637 * Changed the `say' client operation's interface to accept
2638 new `type' argument to indicate the type of the message sent
2639 by the library. The application may filter the library's
2640 messages according the type. The affected file is the
2641 lib/silcclient/silcapi.h.
2643 * Added two new functions to lib/silcclient/silcapi.h:
2644 silc_client_del_client and silc_client_del_client_by_id.
2645 Affected file lib/silcclient/idlist.c.
2647 * Moved the clientincludes.h from includes/ to silc/ and
2648 serverincludes.h from includes/ to silcd/.
2650 * The modes for the CMODE and CUMODE are now passed as
2651 uint32 for application with COMMAND_REPLY. The affected
2652 file is lib/silcclient/command_reply.c.
2654 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2656 * /WHOIS without arguments shows client's own information.
2657 Affected file lib/silcclient/command.c.
2659 * Changed PING to not accept any arguments. The specs
2660 says that client can ping only the connected server so
2661 requiring an argument is not needed. Affected file is
2662 lib/silcclient/command.c.
2664 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2666 * Fixed a fatal bug in private message sending and reception
2667 encryption and decryption when using private message keys.
2668 The implementation was incorrect and did not follow the
2669 specification. It causd that some of the message were
2670 lost since it did not use the sending and receiving keys
2671 as the protocol suggests. This has been fixed and will cause
2672 incompatibilities with older clients when sending private
2673 message encrypted with private message keys. Affected files
2674 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2675 and various other in Irssi SILC Client.
2677 Added `responder' boolean argument to the functions
2678 silc_client_add_private_message_key[_ske] to indicate when
2679 the key is added as responder or initiator of the key
2682 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2684 * Removed the silc_ske_check_version function and created
2685 a SilcSKECheckVersion callback. Added also a function
2686 silc_ske_set_callbacks that is now used to set all SKE
2687 callbacks. The callback functions are not given to
2688 the SKE functions anymore, but this function is used to
2691 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2693 * Added `silc_version' argument to the silc_client_alloc
2694 to define the version of the application for the library.
2695 The library will use the version string to compare it
2696 against the remote host's (usually a server) version
2697 string. Affected file lib/silcclient/silcapi.h
2699 * Added the KE protocol context to Key Agreement context
2700 in client library so that we can abort the SKE if it
2701 is in process when we get timeout. Affected file is
2702 lib/silcclient/client_keyagr.c.
2704 * Do not resolve the client ID forever if it returns in the
2705 first time that such client does not exist. This was done
2706 for example with private message. Affected file is
2707 lib/silcclient/client_prvmsg.c.
2709 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2711 * Do not add regex.h for WIN32. The affected file
2712 includes/silcincludes.h.
2714 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2715 not work yet 100%. It generates the DLL's automatically
2716 when compiling with --with-win32 under cygwin.
2718 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2720 * lib/contrib/regex.c is not compiled on WIN32.
2722 * Added silc_net_get_socket_opt function to the
2723 lib/silcutil/silcnet.h.
2725 * Added includes/silcwin32.h for WIN32 specific includes
2728 * Do not use ptime structure or any of the posix process
2729 functions on WIN32 in lib/silccrypt/silrng.c.
2731 * Added silc_gettimeofday to provide generic function
2732 for struct timeval on all platforms. Added the function
2733 to lib/silcutil/silcutil.h.
2735 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2737 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2738 library as they clearly belong there. As a plus side we
2739 can make the actual socket connection routines platform
2742 Added also new generic function silc_socket_read and
2743 silc_socket_write (that used to be silc_packet_[read/write].
2744 The implementation of these are platform specific.
2746 * Added WIN32 specific routines of silc_socket_[read/write]
2747 to lib/silcutil/win32/silcwin32sockconn.c.
2749 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2751 * Added preliminary support for native WIN32 compilation under
2752 cygwin (using the -mno-cygwin option for GCC) to the
2753 ./configure.in.pre. The --with-win32 now prepares the
2754 compilation for native WIN32.
2756 * Rewrote the SILC Scheduler interface in the file
2757 lib/silcutil/silcschedule.h. The scheduler is now context
2758 based and does not have anymore any global static scheduler.
2759 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2760 and created lib/silcutil/win32 directory for WIN32 based
2763 * Added Unix specific network routines to the
2764 lib/silcutil/unix/silcunixnet.c and the old
2765 lib/silcutil/silcnet.c includes now only generic routines.
2767 Added WIN32 specific network routines to the
2768 lib/silcutil/win32/silcwin32net.c.
2770 * Added Unix specific utility functions from the
2771 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2773 * Added WIN32 SILC Scheduler to the file
2774 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2777 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2779 * Do not handle JOIN notify in the server if the target client
2780 is not registered (idata->registered == FALSE). The affected
2781 file is silcd/packet_receive.c.
2783 * Update the nickrec->founder in event_cumode in the Irssi SILC
2784 client. Affected file irssi/src/silc/core/silc-channels.c.
2786 * Fixed the CUMODE_CHANGE notify handling in the server when
2787 server and router are announcing their clients on channels.
2788 Now the mode changes are saved and notified correctly. The
2789 affected file is /silcd/packet_receive.c.
2791 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2792 They really did not replace the cache entry in the ID Cache.
2793 Now they do that. Affected file silcd/idlist.c.
2795 * Fixed the KICK notify handling in the Irssi SILC client to
2796 update the channel records so that the kicked client does not
2797 appear to be on the channel. The affected file is
2798 irssi/src/silc/core/silc-channels.c.
2800 * Always update the conn->current_channel when executing command
2801 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2803 * Fixed the KILL notify handling in Irssi SILC client to remove
2804 the killed client on all channels.
2806 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2808 * Fixed the silc_parse_command_line to remove extra spaces
2809 from the start and end of the arguments. Affected file is
2810 lib/silcutil/silcutil.c.
2812 * Cancel and free any active protocol in the function
2813 silc_server_close_connection. Affected file silcd/server.c.
2815 * Cancel and free any active protocol in the function
2816 silc_client_close_connction. Affected file is
2817 lib/silcclient/client.c.
2819 * Do not execute the KILL command for clients that are in
2820 history (ie. they are not in the network). Affected file is
2823 * Fixed KILL notify handling, client does not crash anymore.
2824 Affected file irssi/src/silc/core/silc-channels.c.
2826 * Reduced the default packet buffer size from 2048 to 1024 in
2827 lib/silccore/silcpacket.c.
2829 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2830 counter to the SKE context that is incresed when the SKE library
2831 performs async operation outside the library. If the outside
2832 process frees the SKE context and FREED status will be set
2833 and the library will detect after the sync operation that the
2834 libary is freed. The affected files are
2835 lib/silcske/silcske[_status].[ch].
2837 * Resolve the client entry information in the function
2838 silc_client_channel_message to assure that NULL pointer is not
2839 passed as client entry to the application. */
2841 * Fixed the task timeout calculation to assure that there is
2842 never negative timeouts. The affected file is
2843 lib/silcutil/silcschedule.c.
2845 * Fixed the channel user mode notification sending in server.
2846 It was sent point-to-point to the router (or to server by router)
2847 but it needs to be destined to a channel. The routines now
2848 supports sending the channel user mode notifys to the channels
2849 when announcing clients and channels. Affected files are
2850 silcd/server.c and silcd/packet_receive.c.
2852 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2853 It did not actually replace the old channel entry in the cache.
2854 Affected file lib/silcclient/client_notify.c.
2856 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2858 * Fixed a possible crash in silc_packet_send_prepare. It now
2859 assures always that there is enough space in the buffer and
2860 at the tail area of the buffer (for MAC).
2862 Fixed the inbound buffer reallocation in silc_packet_read.
2863 It was old code and did not handle the reallocation correctly.
2866 The affected file is lib/silccore/silcpacket.c.
2868 * Fixed buffer overflow in silc_parse_nickname in the file
2869 lib/silcutil/silcutil.c.
2871 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2873 * make install generates new server keys only if there is not
2876 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2878 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2879 Added check that if the NOREPLY is set then we will not send
2880 the away message. This avoids infinite loop of away messages
2881 if both clients are away. The affected file is
2882 lib/silcclient/client_prvmsg.c.
2884 * Fixed client crash if /NICK was given without arguments.
2885 Affected file lib/silcclient/command.c.
2887 * Server does not send the invite list in INVITE command back
2888 to the client if the list was not altered. Added this notion
2889 to the protocol spec as well. Affected file silcd/command.c.
2891 Fixed possible crash in INVITE command by checking the
2892 value of silc_server_get_client_route command.
2894 * Fixed the INVITE notify type handling. The arguments are now
2895 taken in correct order and client does not crash. The affected
2896 file is irssi/src/silc/core/silc-channels.c.
2898 Removed the "Inviting xxx to channel" message from the
2899 client library away and let the application handle it.
2900 Affected file lib/silcclient/command.c. Added that message
2901 to Irssi SILC client's message formats.
2903 * Fixed CMODE command crash in client. It now checks the
2904 amount of arguments correctly and does not crash. The affected
2905 file is lib/silcclient/command.c.
2907 * Do not create new channel automatically in silc_channels_join
2908 but check whether the channel by that name already exists.
2909 Affected file irssi/silc/core/silc-channels.c.
2911 * Do not send the SERVER_SIGNOFF to router if the disconnected
2912 entity was the router. Affected file silcd/server.c.
2914 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2915 SILC client as it was missing from there.
2917 Added the handling of the KICK notify to the Irssi SILC client
2918 as it was missing. Added "you have been kicked" message to
2919 Irssi SILC client's message modules formats.
2921 Added the handing of the KILL notify to the Irssi SILC client
2922 as it was missing. Added the kill message module formats
2925 The affected file is irssi/src/silc/core/silc-channels.c.
2927 * The router did not save the channel mode the server announced.
2928 Affected file silcd/packet_receive.c.
2930 * Fixed a possible crash in INFO command in server. If the
2931 server did not provide the server info it crashed. Affected
2932 file silcd/command.c.
2934 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2936 * Fixed the GETKEY command in the server to check also the
2937 global list. Otherwise the GETKEY would not work correctly
2938 in normal SILC server. Affected file silcd/command.c.
2940 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2942 * Fixed GETKEY crash, it crashed if the command did not succseed.
2944 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2946 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2947 is now real and not just an macro interface to GMP.
2949 Removed the entire GMP from the source tree and imported new
2950 NSS MPI library instead. Reason for removing GMP is that it is
2951 extremely large and compiles extremely slow. The NSS MPI
2952 is only a few files and compiles in less than 10 seconds.
2953 The speed is also about the same as GMP. The MPI is imported
2954 to lib/silcmath/mpi.
2956 If the system has GMP installed we will still use the GMP.
2957 If it is not then the NSS MPI will be compiled.
2959 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2961 * Merged a long nickname (127 characters long) crash bugfix from
2962 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2964 * Merged a freed memory reference bugfix from Irssi CVS tree.
2965 Affected file irssi/src/core/commands.c.
2967 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2969 * Added the server's public key sving and verification to the
2970 server when performing the SKE. This was missing and the
2971 remote server's (or router's) public key was accepted without
2972 checking whether we have it previously or trust it at all.
2973 Affected file silcd/protocol.c.
2975 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2977 * Check in the silc_server_timeout_remote if protocol is active
2978 and make sure that the protocol's final callback is called so
2979 that all memory if freed. Affected file silcd/server.c.
2981 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2983 * silc_server_whois_send_reply crashed the server if the nickname
2984 was 127 characters long. Affected file silcd/command.c.
2986 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2988 * Added sanity check to the silc_server_new_client. If the hostname
2989 is provided inside username then check that the provided hostname
2990 really is the same as the resolved one. If the hostname was not
2991 resolved then check it from the public key. Affected file is
2992 silcd/packet_receive.c.
2994 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2995 if the server disconnected us and the connection is not valid
2996 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2998 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2999 the library to the lib/silcutil/silcutil.[ch].
3001 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3003 * Close log file after open. Affected file
3004 lib/silcutil/silclog.c.
3006 * Check whether sock == NULL in silc_client_send_packet and return
3007 if it is. Affected file lib/silcclient/silcclient.c.
3009 * Check rec->entry == NULL in the Irssi SILC Client before
3010 sending the channel message. Affecte file is
3011 irssi/src/silc/core/silc-servers.c.
3013 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3015 * Merged a splitted window bugfix from Irssi CVS tree. The
3016 affected file is irssi/src/fe-text/textbuffer-view.c.
3018 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3019 It did not print nickname.
3021 * Improved the distributions system a bit.
3023 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3025 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3026 irssi/src/fe-text/gui-window.c.
3028 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3029 to in-active server. The affected file is
3030 irssi/src/silc/core/client_ops.c.
3032 * Resolve the client in USERS command reply if the entry does
3033 not have username resolved. The affected file is
3034 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3035 command to WHOIS command to really resolve stuff. The USERS
3036 is not used any more in any critical section so WHOIS can
3037 be used even though it might be slower than IDENTIFY.
3039 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3042 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3044 * Changed the protocol API a bit more consistent in the
3045 lib/silccore/silcprotocol.[ch].
3047 * Changed the following headers to ROBODoc format:
3049 lib/silccore/silcpayload.h
3050 lib/silccore/silcprotocol.h
3051 lib/silccore/silcsockconn.h
3053 All core library headers are now formatted.
3055 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3057 * Fixed a bug in Irssi SILC client; do not show that you are
3058 server/router operator if you really are not. Affected file is
3059 irssi/src/silc/core/client_ops.c.
3061 * Renamed silc_command_free_payload to silc_command_payload_free.
3062 Affected file lib/silccore/silccommand.h
3064 * Added silcmath.h to include the prototoypes of various routines
3065 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3068 * Changed the following headers to ROBODoc format:
3070 lib/silccore/silcchannel.h
3071 lib/silccore/silccommand.h
3072 lib/silccore/silcid.h
3073 lib/silccore/silcidcache.h
3074 lib/silccore/silcmode.h
3075 lib/silccore/silcnotify.h
3076 lib/silccore/silcpacket.h
3077 lib/silcmath/silcmath.h
3079 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3081 * Added checking to the server code not to start the server if
3082 ciphers and stuff are not configured properly. Affected files
3083 silcd/serverconfig.[h] and silcd/server.c.
3085 * Changed the layout of the header files of the public interfaces
3086 in the SILC libraries. The new layout supports ROBODoc
3087 documentation tool (and some others) so that it is easy to create
3088 a library reference manual. All the other headers and source
3089 code must still follow the CodingStyle document. Also source
3090 code must not include these ROBODoc stuffs, only the headers.
3091 Furthermore, all public interface headers must now be named
3092 by using `silc' prefix, example: silcapi.h, silccipher.h.
3093 Some files were renamed due to this. All the other headers
3094 must not be used as public interfaces. I will update the
3095 CodingStyle document later. Changed following headers, so far:
3097 lib/silcclient/silcapi.h
3098 lib/silccore/silcauth.h
3099 lib/silccore/silcprivate.h
3100 lib/silccrypt/silcdh.h
3102 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3106 * Removed silc_client_packet_send_flush from the client library
3107 as it is not needed. Affected file lib/silcclient/client.[ch].
3109 * Added printing of message of unresolved authentication method
3110 to the Irssi SILC client. Added it to the module formats.
3111 Removed the same message from the client library.
3113 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3115 * Added new distribution feature, DISTLABEL. Every distribution
3116 can define own preprocessor label that can be used in the
3117 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3118 file distributions, acconfig.h.pre and prepare.
3120 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3122 * Added Makefile.defines_int to include the actual definitions
3123 for Makefile.defines.in. Tested the new distribution system,
3124 created distributions and tested installation.
3126 * Added AWAY message printing to the Irssi SILC client. Added
3127 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3129 * Added SCONNECT command to call the SILC's CONNECT command.
3130 Cannot use CONNECT directly since Irssi uses that internally.
3131 Affected file irssi/src/silc/core/silc-servers.c.
3133 Added ACTION local command. It is same as ME command but takes
3134 the channel as mandatory argument.
3136 Rewrote some of the Irssi's help files to suite for SILC
3139 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3141 * Added Makefile.defines[.in] that should for now on be included
3142 in all Makefile.am file in the source tree. That file includes
3143 all common compilation definitions for SILC source tree.
3145 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3147 * Minor changes to the ./prepare script to change the package
3148 name according the distribution name to the configure.in.
3150 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3152 * Created new distribution system. Added file `distributions'
3153 that defines all the distributions that can be created out of
3154 the SILC source tree. The ./prepare script now reads that
3155 file to determine how to prepare the distributions. The
3156 first argument to the ./prepare is the name of the distribution
3157 and second is the version of the distribution. If given
3158 without arguments it creates the default (toolkit) distribution
3159 with the default version (defined in ./prepare).
3161 All Makefile.am files that are subject to the distributions
3162 are now named as Makefile.am.pre. These are ./Makefile.am
3163 and lib/Makefile.am. Others may be changed later.
3165 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3167 * Added invite list, ban list, some key management and connection
3168 error message printing to module formats in the Irssi SILC client.
3170 * Added new silc_client_set_away_message to set the away message
3171 that is back to the person who sent private message. The
3172 affected file lib/silcclient/silcapi.h and the
3173 lib/silcclient/client_prvmsg.c.
3175 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3177 * Fixed the private message sending in the Irssi SILC client,
3178 added local command KEY to the Irssi SILC client.
3180 Added key management and key agreement message formats to the
3181 irssi/src/fe-common/silc/module-formats.[ch].
3183 Added USERS (alias WHO) printing, server/router operator
3184 indication and LIST command printing to the module formats.
3186 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3188 * Fixed channel joining notify handling, cumode notify handling
3189 from Irssi SILC client.
3191 * Added SILC specific module-formats to the Irssi SILC client so
3192 that SILC specific message hilighting, colors etc is possible.
3193 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3195 Added channel mode, channel user mode, actions, notices,
3196 whois and whowas printing to the the module-formats.c.
3198 * Fixed a bug in channel deletion in the server. The channel
3199 is not left to the cache even if the channel founder auth mode
3200 is set when there are no users anymore on the channel. Affected
3201 file silcd/server.c.
3203 * The silc_net_localhost now resolves the entire hostname including
3204 the domain name. Affected file lib/silcutil/silcnet.c.
3206 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3208 * Changed the ask_passphrase client operation to be ascynchronous.
3209 It has now a completion callback and a context that the
3210 application must call after it has got the passphrase from
3211 the user. Affected files lib/silcclient/silcapi.h,
3212 lib/silcclient/protocol.c, lib/silcclient/command.c and
3215 Added SilcAskPassphrase callback that the application calls
3216 to deliver the passphrase to the library.
3218 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3219 The public key verification and especially a certificate
3220 verification is asynchronous procedure.
3222 Added new SILC_SKE_STATUS_PENDING status to indicate the
3223 request is pending and a callback will be called to finalize
3226 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3227 indicate that remote end did not send its public key (or
3228 certificate), even though we require it. Added check for this
3229 condition in the SKE. This was a security bug, now fixed.
3231 Defined new SilcSKEVerifyCbCompletion callback that is called
3232 when the verification process is completed.
3234 The affected files lib/silcske/silcske_status.h and
3235 lib/silcske/silcske.[ch].
3237 * Changed the verify_public_key client operation to be async
3238 as well. Defined SilcVerifyPublicKey callback that is used to
3239 indicate the success of the public key verification process.
3241 Changed the server and client to use the new async client
3244 * Changed the Irssi SILC client's internal scheduler to be called
3245 twice as many times as it used to be. As a result the client
3246 should be a bit faster now. Affected file is
3247 irssi/src/silc/core/silc-core.c.
3249 * Added support to Irssi SILC client of asynchronous public key
3250 verification and passphrase inquiry. Affected file is
3251 irssi/src/silc/core/silc-core.c.
3253 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3255 * Do not say "You have left channel %s" in client library.
3256 Moved it to the application. Affected files are
3257 lib/silcclient/command.c and silc/client_ops.c.
3259 * Fixed silc_client_get_clients. Command context was not
3260 duplicated and was freed memory in the callback. Affected
3261 file lib/silcclient/idlist.c.
3263 * Do not say "you are now talking..." on JOIN command in the
3264 client library. The appliation must handle it.
3266 * Do not say ".. changed topic to" in command reply in the
3267 client libary. The application must handle it.
3269 * Fixed TOPIC command sending in the client library.
3271 * Fixed a memory leak in silc_client_command_free in the file
3272 lib/silcclient/command.c.
3274 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3276 * Imported a modified version of Irssi client to the source tree.
3277 The Irssi will be used to create a new client called
3278 Irssi SILC. Imported to irssi/.
3280 Added silc_core_init_finish function to the Irssi. Affected
3281 file irssi/configure.in.
3283 A lot changes in the Makefile.ams around the irssi tree.
3285 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3287 * Do not rehash if the new size is same as the old size of the
3288 hash table, in the silc_hash_table_rehash*. The affected file
3289 lib/silcutil/silchashtable.c.
3291 * Replaced hash_table_del_by_context calls from the server
3292 (when channel->user_list and client->channels) to the
3293 hash_table_del as it is sufficient and faster.
3295 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3297 * Added silc_hash_table_list, silc_hash_table_get and the
3298 SilcHashTableList structure to provide an alternative way to
3299 traverse the hash table. The affected files are
3300 lib/silcutil/silchashtable.[ch].
3302 * Changed the server's idlist routines to use the hash table
3303 routines to optimize the code.
3305 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Replaced the client entry's `channel' list and channel entry's
3308 `user_list' list to hash tables for optimized lookup. Changed
3309 the code to use the hash table interface around the code.
3310 Affected file lib/silcd/idlist.[ch].
3312 * Added `auto_rehash' boolean argument to the function
3313 silc_hash_table_alloc to indicate whether the hash table should
3314 auto-rehash when it thinks is appropriate time. It will
3315 increase the hash table size if the there is twice as much
3316 entries in the table than the size of the table, and will
3317 decrease the size if there are twice as less entries than
3318 the size of the table.
3320 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3322 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3324 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * silc_idcache_purge_by_context deletes the entry now by context
3327 as it is supposed to do. Affected file lib/silccore/idcache.c.
3329 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3330 client is not anymore valid (WHOWAS givens the info) and not
3331 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3333 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3335 * Removed the `data' and `data_len' arguments from the ID Cache
3336 interfaces and added `name' argument. ID Cache does not handle
3337 anymore the binary data only a names associated with given ID.
3339 * When hashing a Client ID with silc_hash_id the entire ID is
3340 not hashed anymore, instead only the hash of the Client ID is
3341 hashed. This way we can access the Client ID from the cache
3342 with Client ID but with the hash of the ID (which is a hash of
3343 the nickname) as well without any difference in performance.
3345 Added also silc_idcache_find_by_id_one_ext to do one on one
3346 searching when we have the actual ID. Added also function
3347 silc_hash_client_id_compare. The affected files are
3348 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3350 * When hashing the name associated with a ID it is always done
3351 in lowercase. This way we can access the cache without worrying
3352 about case-sensitivity, even though, for example nicknames are
3355 * Fixed a bug in server with channel message sending. It put
3356 wrong ID type as destination ID. The affected file
3357 silcd/packet_send.c.
3359 * silc_idcache_del_by_context now deletes from all hash tables
3360 by context. Affected file lib/silccore/idcache.c.
3362 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3364 * Changed the client library to use the new ID Cache interface.
3365 Changes around the source tree.
3367 * Added silc_hash_table_rehash_ext to rehash with specific
3368 hash function. Affected file lib/silcutil/silchashtable.[ch].
3370 * Added silc_hash_string_compare to compare two strings in the
3371 hash table. Affected file lib/silcutil/silcutil.[ch].
3373 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3375 * Added new function silc_idcache_del_by_context into the
3376 lib/silccore/idcache.[ch].
3378 * Changed the server's ID list routines to use the new ID Cache
3379 interface. Changes around the source tree.
3381 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3383 * Added silc_hash_table_del[_by_context]_ext functions in to the
3384 lib/silcutil/silchashtable.[ch].
3386 Removed silc_hash_table_find_all* routines and added new
3387 silc_hash_table_find_foreach to replace them.
3389 Added silc_hash_table_replace_ext function as extended
3390 replacing function. Separated the simple hash table interface
3391 from the extended hash table interface in the file
3392 lib/silcutil/silchashtable.h.
3394 * Fixed minor bugs and changed it to use some of the new
3395 hash table functions in lib/silccore/idcache.c
3397 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3399 * Added new function silc_hash_table_find_all to return all keys
3400 in the hash table by the specified key. As the hash table is
3401 collision resistant it also makes it possible to have several
3402 duplicate keys in the hash table. This function may be used to
3403 find all of the keys from the hash.
3405 Added user_context arguments to the SilcHashFunction,
3406 SilcHashCompare and SilcHashDestructor to deliver user specified
3409 Added new fuctions silc_hash_table_find[_all]_ext to do
3410 extended lookup with specified hash and compare functions and
3411 specified user contexts.
3413 Added new function silc_hash_table_add_ext to add the key
3414 with specified hash function and user context.
3416 Added new function silc_hash_table_foreach to traverse all
3417 entrys in the hash table. Added SilcHashForeach callback
3420 Added new function silc_hash_table_del_by_context to delete
3421 the entry only if the context associated with the key matches.
3423 Affected files are lib/silcutil/silchashtable.[ch].
3425 * Removed silc_hash_[server/client/channel]_id and added just
3426 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3427 silc_hash_id_compare to compare two ID's using as the hash table
3428 comparison function. Added also silc_hash_data to hash
3429 binary data and silc_hash_data_compare to compare it.
3431 * Removed silc_idlist_find_client_by_hash as it is not needed
3432 anymore. Affected file silcd/idlist.[ch].
3434 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3435 to use internally the SilcHashTable. The new ID Cache is a lot
3436 faster than the old one. Some of the ID Cache interface was also
3437 rewritten and obsolete and stupid functions were removed.
3439 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3441 * Added entry_count field to the SilcHashTable to keep the number
3442 of the entries in the table. Implemented the function
3443 silc_hash_table_rehash. Added new function
3444 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3446 Fixed a minor bug in silc_hash_table_free.
3448 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3449 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3450 into the lib/silcutil/silcutil.[ch].
3452 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3454 * Implemented a collision resistant hash table into the
3455 lib/silcutil/silchashtable[ch]. See the header and the source
3456 for the SilcHashTable API.
3458 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3460 * Merged dotconf version 1.0.2 into lib/dotconf.
3462 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3464 * Do not compile anything in lib/silcsim/* if the SIM support
3465 is not enabled. The tree should now compile without problems
3468 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Compiled the SILC under cygwin. Compiled and tested briefly
3471 without problems. More tests needed. The SIMs didn't compile
3474 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3476 * Fixed possible crash in silc_get_username in the
3477 lib/silcutil/silcutil.c.
3479 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3481 * Fixed a va_arg in silc/client_ops.c.
3483 * Oops, RC5 routines were named AES and caused some problems
3484 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3486 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3488 * Added new SilcIDIP structure into the lib/silccore/id.h and
3489 replaced the old `ip' fields from all SILC ID's to that type.
3490 This is a step towards IPv6 support.
3492 The silc_id_get_len takes now the ID as an extra argument.
3493 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3494 both IPv4 and IPv6 based ID's.
3496 The affected files are lib/silccore/id.[ch] and other files
3497 around the tree using these routines.
3499 * Removed the ID length arguments in server from various
3500 silc_server_send_notify_* routines -> they are not needed
3503 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3505 * Fixed memory leak in silc_encode_pem_file in the file
3506 lib/silcutil/silcutil.c.
3508 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Check minor version as well in the SKE. Affected files are
3511 silcd/protocol.c and lib/silcclient/protocol.c.
3513 * Added --identifier option to the server so that an identifier
3514 can be when creating the public key for the server. Affected
3515 file is silcd/silcd.c.
3517 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3518 lib/silccrypt/silcpkcs.c.
3520 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3522 * Register default ciphers and stuff when using -C option with
3523 the server. Affected file sildc/silcd.c.
3525 * Put back the servers public key filename format, it is better
3526 than the new one. For now, the client keys are saved with the
3527 new filename format. The affected file silc/client_ops.c.
3529 * Implemented the Cipher API for the rest of the ciphers that
3530 did not implement it or implemented it the wrong way.
3532 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3534 * Register default ciphers and stuff when using the -S option
3535 in the client. Affected file silc/silc.c. Same also when
3536 creating new key pair with -C option.
3538 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3540 * Fixed the silc_verify_public_key client operation function to
3541 save the public keys differently. The fingerprint is now
3542 used as filename and not the hostname. This way also the
3543 client keys are saved uniquely and not with hostnames. The
3544 affected file is silc/client_ops.c.
3546 * Trimmed the silc_hash_fingerprint function to remove extra
3547 whitespaces from the end of the fingerprint. The affected
3548 file is lib/silccrypt/silchash.c.
3552 * Added silc_cipher_register_default function to register all
3553 default ciphers. It can be used when configuration files
3554 does not exist and the application does not want any specific
3555 ciphers in any specific order.
3557 The SilcDList is now used as silc_cipher_list dynamically
3558 allocated cipher list. Removed the static list all together
3559 and now all ciphers must be allocated to the dynamic list.
3560 The silc_cipher_alloc routine was changed to check only the
3563 All silc_cipher_* routines that used to return int returns
3566 The affected files lib/silccrypt/silccrypt.[ch].
3568 * The same thing was done to silc_hash_* as for silc_cipher_*
3569 routines. Affected files lib/silccrypt/silchash.[ch].
3571 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3572 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3573 Added also silc_pkcs_[un]register[_default] functions.
3574 Removed the data_context from the PKCS API.
3576 * Added silc_hmac_register_default function to register default
3577 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3578 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3579 to unregister all hmacs at once.
3581 * Register the default ciphers, hash functions, PKCSs and HMACs
3582 if client's configuration file does not exist. The affected
3585 * The client did not load the hash functions from the SIM
3586 modules at all. Added support for this. Affected file is
3587 silc/clientconfig.c.
3589 * When decoding public key with silc_pkcs_public_key_decode, check
3590 the supported algorithm only if PKCS are registered. Affected
3591 file lib/silccrypt/silcpkcs.c. The same was done with the
3592 silc_pkcs_private_key_decode.
3594 * Fixed the SILC List routines to keep the list always in order.
3595 It used to change the list's order when traversing the list but
3596 not it preserves the order. Affected file lib/trq/silclist.h.
3598 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3600 * Added the client library to use the SilcSocketConnection's
3601 reference counter (by silc_socket_dup) to prevent the bug that
3602 the socket object may be freed underneath async operation.
3604 * The name resolv library checking fixes in the configure.in.pre.
3607 * Created new version of the protocol drafts for future
3608 development. The -03 drafts are the ones that will be changed
3609 in the trunk now and the -02 will remain as they are.
3611 * Send list of CUMODE notifys to the router when announcing
3612 the channel users to the router. Affected file silcd/server.c.
3613 If the router receiving channel founder CUMODE for a channel
3614 that already has channel founder it will send CUMODE notify
3615 to the sender to remove the channel founder rights from the
3616 announced client. Affected file silcd/packet_receive.c.
3618 * The CUMODE notify may now use Server ID as well as the entity
3619 who changes the mode. Updated protocool specs.
3621 * Updated INSTALL and README files.
3623 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * New web pages in the http://silc.pspt.fi. The pages was
3630 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3632 * Implemented the [DenyConnectin] config section in the server.
3633 Added silc_server_config_denied_conn to check whether incoming
3634 connection is denied. Affected file silcd/serverconfig.[ch].
3636 * Do not check the ports when checking the incoming configuration
3637 data if the port is 0, meaning any. Affected file is
3638 silcd/serverconfig.c.
3640 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3642 * Fixed buffer overflow in silc_string_compare in the file
3643 lib/silcutil/silcutil.c.
3645 * Fixed double free in silc_server_command_leave in the file
3648 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3650 * Fixed the version checking in the server. Affected file is
3653 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3655 * Fixed the configuration data fetching when accepting new
3656 connections in the server. Affected file silcd/server.c.
3658 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3660 * Added `sender_entry' argument to the function
3661 silc_server_packet_relay_to_channel so that we can check
3662 whether some destination actually belongs to the same route
3663 the sender belongs (ie, we must not resend the packet to the
3664 sender). Affected file silcd/packet_send.[ch].
3666 * Added `servername' field to the SilcClientEntry in the server
3667 to hold the name of the server where client is from. Affected
3668 file is silcd/idlist.h.
3670 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * Moved the channel message encrypting in the router betwen
3673 router connections from silc_server_channel_message to the
3674 silc_server_packet_relay_to_channel since we want to check
3675 whether we have anybody channel before encrypting anything.
3676 Affected files silcd/packet_[receive/send].c.
3678 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3680 * Fixed the [AdminConnection] server config section to support
3681 multiple entries. Affected file silcd/serverconfig.c.
3683 * Added support into the server to check the validity of the
3684 incoming connection before executing any KE or authentication
3687 * The connection configuration is now saved to the KE and
3688 connection auth protocol contexts and not fetched anymore in
3689 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3691 * The local hosts listenning address and port is also resolved
3692 now when starting the server. We want to have the socket object
3693 to include the real address and port for the listener. Added
3694 new function silc_net_check_local_by_sock into the files
3695 lib/silcutil/silcnet.[ch].
3697 * Fixed a broadcast bug in server -> do not broadcast if we
3700 * Fixed a routing bug. Do not route broadcast packets ever.
3701 Broadcast packets must be processed always and not routed since
3702 they may be destined to some other host than yourself and thus
3703 would get routed without no good reason. Affected file is
3706 * Added function silc_server_config_is_primary_route to check
3707 whether primary router connection has been configured (a router
3708 configuration that we are initiating). If there is not, we
3709 will assume that there is only two routers in the SILC network
3710 and we will use the incoming router connection as our primary
3711 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3713 * Changed the order of the broadcasting. Broadcast _after_ the
3714 packet has been processed not before. Affected file is
3717 * Fixed a [ClientConnection] parsing bug. The port was never
3718 parsed correctly thus resulting to port 0. Affected file
3719 silcd/serverconfig.c.
3721 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3722 argument and did not set the broadcast packet flag. Affected
3723 file silcd/packet_send.c. Fixed same bug in the function
3724 silc_server_send_notify as well.
3726 * If we receive NEW_ID packet for our own ID in the server, ignore
3729 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3733 * Removed the nickname from the Private Message Payload.
3734 Updated the code and the protocol specs.
3736 * Updated protocol specs for submitting to the IETF.
3738 * Tweaked the Random Number Generator a bit. Affected file
3739 lib/silccrypt/silcrng.c. Exported a new function
3740 silc_rng_[global]_add_noise which can be used to add more
3743 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3745 * Do not parse packets with different timeout when protocol
3746 is active -> may cause problem with rekey. Affected file
3749 * When server receives signoff notify it must not create
3750 new channel key if the client is on any channels since the
3751 sender of the signoff notify will create it.
3753 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3755 * Added printing of error messages during SKE protocol from the
3756 failure packet sent by server during SKE. Affected file
3759 * Removed the client's failure_callback handling with timeout
3760 and handle it immediately when received.
3762 * The SKE library returned wrong type in SUCCESS and FAILURE
3763 packets. They must be 32 bit MSB not 16 bit MSB.
3765 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3767 * Ok, rewrote the logic of the re-key and now it seems to work.
3768 I tested it on high traffic with frequent re-keys without
3769 problems. Added hmac_receive (and renamed hmac to hmac_send)
3770 in SilcClientConnection in lib/silcclient/client.h and
3771 in SilcIDListData in silcd/idlist.h. Also, removed the
3772 SilcPacketParserContext's cipher and hmac fields as they are
3773 not needed anymore and actually caused some problems when
3774 the ciphers and hmac's changed underneath the packet parser.
3776 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3778 * If re-key protocol is active then process the incoming packets
3779 synchronously since we must assure that icoming packets encrypted
3780 with the old key is processed before the new keys is set to
3781 use. This is true other packets than for REKEY packets.
3782 Affected file silcd/server.c. The same was done to client library
3783 as well, affected file lib/silcclient/client.c.
3785 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3787 * Fixed bug in client and server to accept the force send if
3788 the packet is send from silc_[server/client]_packet_process
3789 function. Otherwise the packets are never delivered, oops.
3791 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3793 * Disable force sending of packets when REKEY protocol is active.
3794 We must assure that no packet is sent directly when rekey is
3795 performed. All packets must be sent through packet queue.
3796 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3797 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3798 function is silc_[server/client]_packet_send_real to check
3801 * Replaced the SIM paths from example config files to
3802 /usr/local/modules. Also, make install creates now
3803 /usr/local/silc/logs directory to hold all the SILC server
3806 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3808 * Made the configure.in.pre work on Solaris. Patch by salo.
3810 * Made all ciphers compatible with non-x86 machines. Defined
3811 CBC mode macros into lib/silccrypt/ciphers_def.h.
3813 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Fixed the make install.
3817 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3819 * When MAC computation fails the silc_packet_decrypt returned 0
3820 even though it was supposed to return -1. Fixed this. The
3821 affected file is lib/silccore/silcpacket.c.
3823 * Do not replace the config files in /etc/silc (in make install)
3824 if they already exist. Affected file ./Makefile.am.
3826 * Do not send re-key packets immediately but through packet queue.
3827 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3829 * Changed silc_net_check_host_by_sock to return FALSE if the
3830 IP/DNS could not be resolved. Though, it returns the IP address
3831 now even if it could not resolve it (but returns also FALSE).
3832 Affected file lib/silcutil/silcnet.[ch].
3834 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * Added silc_pkcs_decode_identifier to decode the public key's
3837 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3838 Added also silc_pkcs_free_identifier. Added also new context
3839 SilcPublicKeyIdentifier.
3841 * Added -S option to the silc client. It is used to dump the
3842 contents of the specified public key file.
3844 * Changed the PKCS api to return the public key length when
3845 setting the public key.
3847 * Fixed a fatal bug in the public and private key file loading.
3848 Affected file lib/silccrypt/silcpkcs.c.
3850 * Execute the packet parsing for client with zero (0) timeout
3851 if the protocol is active. Affected file silcd/server.c.
3853 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3855 * Made the key generation options to the silcd program. Added
3856 -C option, equivalent to client's option.
3858 * Added new [ServerKeys] config section to the server. It
3859 configures the server's public and private key.
3861 * Defined generic Public Key Payload into the protocol
3862 specification to send specific type of public keys and
3865 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3866 public key or certificate.
3868 * Implemented the GETKEY command to the server and to the
3869 client library and on user interface.
3871 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3873 * Made preliminary `make install' work.
3875 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3877 * Added SilcServerRekey context into silcd/idlist.h.
3879 * Added the PFS support as defined in the specification to the
3880 SKE protocol. Affected files lib/silcske/*.c.
3882 * Added `ske_group' field to the SilcServerRekey context to hold
3883 the number of the SKE group that is used with PFS in re-key.
3884 Affected file silcd/idlist.h.
3886 * Added PFS re-key support to the server. Affected file is
3889 * Added silc_protocol_cancel to cancel execution of the next
3890 state of the protocol. Affected file is
3891 lib/silccore/silcprotocol.[ch].
3893 * Added the re-key support with and without PFS to the client
3894 library. Re-key is performed once in an hour, by default.
3896 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3897 Added silc_client_rekey_callback and silc_client_rekey_final.
3898 Affected files are lib/silcclient/protocol.[ch] and
3899 lib/silcclient/client.[ch].
3901 * Removed the `hmac_key' and `hmac_key_len' fields from the
3902 SilcClientConnection structure; not needed. Affected file is
3903 lib/silcclient/client.h.
3907 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3909 * Do not ask whether user wants to use the negotiated private key
3910 for private messages, just use it. Affected file is
3911 silc/local_command.c.
3913 * Added `send_enc_key' and `enc_key_len' fields to the
3914 SilcIDListData structure since they are needed in the re-key
3915 phase. Affected file is silcd/idlist.[ch].
3917 * Implemented the simple re-key protocol into the server.
3918 Affected files silcd/server.c and silcd/protocol.[ch]. The
3919 re-key will be performed once in an hour, by default.
3921 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3922 Added silc_server_rekey, silc_server_rekey_callback and
3923 silc_server_rekey_final.
3925 * Removed Tunneled flag from the protocol. Updated the code
3926 and the specifications.
3928 * Adde `pfs' field to the SilcIDListData to indicate whether
3929 the PFS is to be performed in the re-key. Affected file is
3932 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3934 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3935 int64 of at least the xintXX size. If void * is less that 4
3936 bytes uint32 * will be used. Defined bool as boolean.
3938 * Changed _ALL_ unsigned long and unsigned int to uint32,
3939 unsgined short to uint16 in the source tree.
3941 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3942 not handle clients that has entry->data.registered == FALSE.
3943 They are not in the network anymore. Affected file is
3946 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Implemented the sending of the SERVER_SIGNOFF notify in the
3949 server. Affected file is silcd/server.c.
3951 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3952 Added also silc_notify_payload_encode_args into the
3953 lib/silccore/silcnotify.[ch].
3955 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3956 Affected file silcd/packet_receive.c.
3958 * Implemented the SERVER_SIGNOFF notify handling in the client
3959 library. Affected file lib/silcclient/client_notify.c. Also,
3960 implemnted the printing of the SERVER_SIGNOFF info to the
3961 application. Affected file silc/client_ops.c.
3963 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3964 if the deleting was successful. Affected file silcd/idlist.[ch].
3966 * Added support for public key authentication in the connection
3967 authentication protocol in the client library. Affected file
3968 lib/silcclient/protocol.c.
3970 * Changed the server's silc_idlist_get_clients_by_* interface
3971 to support already allocated array so that new entries may be
3972 added to pre-allocated array. Affected file silcd/idlist.[ch].
3973 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3974 and command replies.
3976 * All command reply functions in the server now calls the
3977 pending command callback even if error occured. This way the
3978 error will be delivered to the client as well. Affected files
3979 silcd/command.c and silcd/command_reply.c.
3981 * Fixed INFO command to return local server's info if no server
3982 was provided. Affected file lib/silcclient/command.c.
3984 * Removed RESTART command for good. Updated the code and the
3987 * Rewrote parts of the task system. It is a bit simpler now.
3988 Removed unsued task priorities. The affected files are
3989 lib/silcutil/silctask.[ch].
3991 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3993 * Moved the USERS printing from the library to the application.
3994 Affected files lib/silcclient/command.c and silc/client_ops.c.
3996 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4000 * Added channel key re-key support. The re-key is perfomed
4001 only by the router and is done once in an hour. Added `rekey'
4002 field to the SilcChannelEntry in the server. Affected files
4003 silcd/server.c and silcd/idlist.h.
4005 * Added silc_task_unregister_by_context into the file
4006 lib/silcutil/silctask.[ch].
4008 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4010 * Added SILC_UMODE_GONE mode to indicate when the client is not
4011 present in the SILC network. Added also support to the local
4012 command AWAY that will set this mode. Added support of showing
4013 "xxx is gone" in WHOIS command. The USERS command shows the
4014 gone status as well.
4016 * Fixed setting server and router operator privileges in the
4017 server's UMODE command. Affected file silcd/command.c.
4019 * Merged the SKE KE1 and KE2 payloads into one payload. The
4020 new KE payload is equivalent to the old KE2 payload.
4022 Cleaned up the SKE Start Payload parsing. It now uses the
4023 simple buffer unformatting to do the parsing. A lot faster
4026 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4027 to the SKE that is used to indicate whether both of the SKE
4028 parties should perform authentication. By default only the
4029 responder performs authentication. By setting this flag also
4030 the initiator must do authentication. By default it is unset
4031 since in normal SKE case, client to server connection, only
4032 the responder should do authentication. When doing SKE between
4033 two clients both should perform authentication. Updated the
4034 code and the protocol specs.
4036 * A little fix to IDENTIFY command in the server. Search the
4037 client first by hash not nickname. Affected file is
4040 * Fixed the silc_client_close_connection to support closing
4041 the client to client connections wihtout deleting too much
4042 data. Affected file lib/silcclient/client.c.
4044 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4045 are received if protocol used to be active but is not anymore
4046 the application would crash due to NULL pointer dereference.
4047 Affected files silcd/server.c and lib/silcclient/client.c.
4049 * Added `hash' field to the SilcClientConnection to include
4050 the hash function negotiated in the SKE protocol.
4052 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4053 to set the channel founder authentication data. A client can
4054 claim the founder rights later by providing the authentication
4055 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4056 This way the channel founder can regain the channel founder
4057 privileges even it is left the channel. This works only on
4058 local server and the client must be connected to the same
4059 server to be able to regain the founder rights. Updated the
4060 protocol specs accordingly.
4062 Added support to the CMODE command in the client to set the
4063 founder auth data. Read the README to see how to set it.
4065 Added support to the CUMODE command to claim the founder
4066 rights. Read the README to see how to do it.
4068 Added support for the founder authentication to the Channel
4069 Entry in the server. Affected file silcd/idlist.h.
4071 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4072 server's CMODE command. Affected file silcd/command.c.
4074 * Added the following new functions into lib/silccore/silcauth.[ch]:
4075 silc_auth_get_method and silc_auth_get_data.
4077 * The server now saves the remote hosts public key to the
4078 SilcIDListData pointer. Affected file silcd/protocol.c.
4080 * The normal server now does not remove the channel entry from
4081 the cache if the founder authentication data is set. It used
4082 to remove it if the founder was the last one on the channel on
4083 the server and left the channel. The auth data is saved and
4084 if the channel is re-joined later the old entry is used with
4085 the old auth data. Affected files silcd/command_reply.c and
4088 * Removed the `pkcs' field from the SilcIDListData structure
4089 in the server; it is not used. Affected file silcd/idlist.h.
4091 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4093 * Fixed packet processing on slow links. Partial packets were
4094 never re-processed because the incoming data buffer was cleared
4095 by the application. Application must not directly clear the
4096 sock->inbuf, the packet processing routines handle it. Fixed
4097 this in client library and in server.
4099 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4101 * Fixed the WHOIS and IDENTIFY send reply function to really
4102 check whether to send list or just one entry. Affected file
4105 * Cleaned up the LEAVE command's channel key distribution. The
4106 affected file silcd/command.c.
4108 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4109 can enforce the channel mode as well. In that case the ID
4110 includes the ID of the server. The code now enforces the
4111 mode change if the router have different mode than the server.
4113 * The notify client operation with CMODE_CHANGE notify can now
4114 return NULL client_entry pointer if the CMODE was not changed
4115 by client. Application must check for this.
4117 * Added <Server ID> argument to INFO command to support server
4118 info fetching by Server ID.
4120 * Added silc_server_announce_get_channel_users to get assembled
4121 packets of channel users of the specified channel. Affected
4122 file silcd/server.[ch].
4124 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4125 was freed underneath the ID Cache.
4127 * Re-announce clients when the server received CHANNEL_CHANGE
4128 notify from the router. Affected file silcd/packet_send.c.
4130 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4132 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4133 crashed since it did not handle the fact that there is no cipher
4134 called "3" and didn't check the error condition. Now fixed.
4136 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4137 flag. It can be used to send message requests.
4139 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4141 * Implemented the RESTART command in the client.
4143 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4144 notice type messages. Added notice printing to the user
4147 * The channel keys are not re-generated if the channel's mode
4148 is PRIVKEY, ie private key on the channel exists. Affected
4149 files silcd/server.c and silcd/command.c.
4151 * Fixed a little bug in channel message delivery when channel
4152 private keys are set in the server. Affected file is
4153 silcd/packet_send.c.
4155 * Changed the setting on channel->on_channel = TRUE from the
4156 silc_client_save_channel_key to the JOIN command reply. The
4157 key payload is not received if the private channel key is set.
4158 Affected file lib/silcclient/command_reply.c and the
4159 lib/silcclient/client_channel.c.
4161 * When the CMODE_CHANGE notify is sent and the channel private
4162 key mode is removed the channel key must be re-generated in
4163 other cells as well. Added this support for the router in the
4164 silcd/packet_receive.c.
4166 * Added new local command NOTICE to send notice message on
4167 channel. Affected file silc/local_command.[ch].
4169 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4171 * Added new local command ME to the client. It is used to send
4172 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4173 some action. Affected file silc/local_command.[ch].
4175 * Changed channel_message and private_message client operations
4176 to deliver the message flags to the application. Added also
4177 the `flags' arguments to the silc_client_send_channel_message
4178 and silc_client_send_private_message functions. Affected file
4181 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4183 * Redefined the Private Message Payload to support private message
4184 keys and to support the new private message flags. Updated
4185 the protocol specs. Flags makes it possible to have for example
4186 CTCP style messages.
4188 * Added new type SilcPrivateMessagePayload and defined an API
4189 for it in the lib/silcclient/silcprivate.[ch].
4191 * Tested private message private keys successfully. Tested the
4192 private message key set, unset and list commands with the new
4195 * Redefined the Channel Message Payload to include the channel
4196 message flags (equal with private message flags) to support
4197 for example CTCP style messages.
4199 * Defined some of the message (for channel and private message)
4200 flags. Updated the protocol specs and added the flags to the
4201 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4203 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * Added SilcKeyAgreementStatus type to the key agreement routines
4206 to indicate the current status and error if one occured.
4207 The status types are defined in the lib/silcclient/silcapi.h.
4209 * Added new local command KEY that is used to set and unset private
4210 keys for channels, set and unset private keys for private messages
4211 with remote clients and to send key agreement requests and
4212 negotiate the key agreement protocol with remote client. The
4213 key agreement is supported only to negotiate private message keys,
4214 it currently cannot be used to negotiate private keys for channels,
4215 as it is not convenient for that purpose.
4217 * Fixed a minor pending callback setting bug in the function
4218 silc_client_get_client_by_id_resolve, now the function works.
4219 Affected file lib/silcclient/idlist.c.
4221 * Added function silc_net_get_local_port to get local bound
4222 port by socket. Added to lib/silcutil/silcnet.[ch].
4224 * Added `sockets' and `sockets_count' fields to the SilcClient
4225 object. They hold the sockets of the listenning sockets in
4226 the client. Listenning sockets may be for example the key
4227 agreement server. Affected file lib/silcclient/client.[ch].
4228 Added functions the silc_client_add_socket and the
4229 silc_client_del_socket. They are exported to the application
4232 * Added ~./silc/clientkeys to support other client's public keys.
4234 * Renamed verify_server_key client operation to verify_public_key
4235 and added one argument to indicate the type of the connection
4236 (server, client etc.).
4238 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4240 * Added silc_server_connection_auth_request to handle the
4241 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4242 silcd/packet_receive.[ch].
4244 * Added silc_server_send_connection_auth_request into the
4245 silcd/packet_send.c to send the connection auth request packet.
4247 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4250 * Fixed the public key authentication in responder side in the
4251 server. The `auth_data' pointer includes the SilcPublicKey
4252 not the path to the public key. Affected file silcd/protocol.c.
4254 * Implemented the public key authentication in the initiator side
4255 in the server. Affected file silcd/protocol.c.
4257 * Removed the [RedirectClient] config section from the server
4258 configuration. Is not needed and I don't want to implement it.
4260 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Cleaned up the CMODE command in the server. It now works
4263 correctly and supports all the modes defined in the protocol.
4264 Affected file is silcd/command.c.
4266 * Added `hmac_name' field to the SilcChannelEntry in the server
4267 to hold the default HMAC of the channel. It can be set when
4268 creating the channel (with JOIN command). Affected files
4271 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4272 type to indicate the change of the current cipher and hmac
4273 on the channel. Client can safely ignore the <cipher> argument
4274 (if it chooses to do so) since the CHANNEL_KEY packet will
4275 force the channel key change anyway. The <hmac> argument is
4276 important since the client is responsible of setting the new
4277 HMAC and the hmac key into use.
4279 * Fixed the CMODE command in the client library as well.
4281 * Tested CMODE command in router environment successfully.
4283 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Show the version of the remote client (or server) when connecting
4286 to the server. It is logged to the log file. Affected file
4287 is silcd/protocol.c.
4289 * Fixed the KILLED notify handling in the client library. The
4290 client must be removed from all channels when receiving the
4293 Also, do not remove the client entry when giving the KILL
4294 command but when the KILLED notify is received.
4296 * Removed silc_idlist_find_client_by_nickname from the server.
4297 Not needed anymore. Affected files silcd/idlist.[ch].
4299 * Implemented the CHANNEL_CHANGE notify type handling to the
4300 server. Affected file silcd/server.c.
4304 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4306 * Added silc_server_send_notify_invite to send the INVITE
4307 notify between routers.
4309 * Implemented the INVITE command correctly to the server.
4311 * Implemented the INVITE notify type handling in the server.
4313 * Implemented the INVITE command to the client library and on the
4316 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4318 * Added function silc_server_get_client_resolve to find the
4319 client entry by ID from all ID lists and then resolve it
4320 (using WHOIS) if it cannot be found. Affected file is
4323 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Implemented the BAN command to the client library.
4327 * The JOIN command in the server now checks the invite list
4330 * Changed the silc_command_reply_payload_encode_va and the
4331 silc_command_payload_encode_va to support that if argument is
4332 NULL it ignores and checks the next argument. Affected file
4333 lib/silccore/silccommand.c.
4335 * Added silc_server_send_notify_ban to send the BAN notify
4336 type between routers.
4338 * Chaned the silc_notify_payload_encode to support that if
4339 argument is NULL it ignores and checks the next argument.
4340 Affected file lib/silccore/silcnotify.c.
4342 * Tested ban lists in router environment successfully.
4344 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4346 * Implemented BAN command to the server, in silcd/command.[ch].
4348 * Removed the BAN and INVITE_LIST modes from the CMODE command
4351 * Added function silc_string_match to regex match two strings.
4352 Affected files lib/silcutil/silcutil.[ch].
4354 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4356 * Redefined parts of the SilcChannelEntry in the server to support
4357 the new ban and invite lists.
4359 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4361 * Redefined the INVITE command. The same command can be used to
4362 invite individuals to the channel but also to manage the invite
4363 list of the channel (to add to and remove from the invite list).
4364 Updated the protocol specs.
4366 * Added new command SILC_COMMAND_BAN that can be used to manage
4367 the ban list of the channel. Updated the protocol specs.
4369 * Removed the channel modes: the SILC_CMODE_BAN and the
4370 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4371 in the CMODE command. The equivalent features are now available
4372 using INVITE and BAN commands. Updated the protocol specs.
4374 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4375 in the network about change in the current ban list. The notify
4376 type is not used by the client.
4378 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4379 support the invite lists.
4381 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * Added new function silc_string_regexify that converts string
4384 including wildcard characters into regex string that can
4385 be used by the GNU regex library. Added into the file
4386 lib/silcutil/silcutil.[ch].
4388 Added silc_string_regex_combine to combine to regex strings
4389 into one so that they can be used as one regex string by
4390 the GNU regex library. Added into the file
4391 lib/silcutil/silcutil.[ch].
4393 Added silc_string_regex_match to match two strings. It returns
4394 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4396 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4398 * Imported GNU regex to the soruce tree into lib/contrib.
4399 Fixed some compiler warning from the regex.c.
4401 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4403 * Fixed MOTD command in the server to work in router environment.
4405 * Fixed the MOTD command in the client library to support
4406 the server argument in the command.
4408 * Added `nickname_len' argument to the silc_idlist_add_client
4409 in the server, as the `nickname' argument may be binary data
4412 * Added silc_idlist_get_channels to return all channels from
4415 * Implemented LIST command to the server. Affected file is
4418 * Implemented the LIST command to the client library and on the
4421 * Added [<user count>] argument to the LIST command reply.
4422 With private channels the user count is not shown.
4424 * Updated TODO and README.
4426 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4428 * The client entry's data.registered must be TRUE even with
4429 global client entry on global client list. The data.registered
4430 is used to check whether the client is anymore in the network,
4431 for example with WHOWAS command so it must be valid.
4433 * Fixed the WHOWAS command in the server. It now actually works
4434 in router environment. Added function into silcd/command_reply.c
4435 silc_server_command_reply_whowas_save.
4437 * Added silc_idlist_purge function to the silcd/idlist.c
4438 to periodically purge the ID Cache.
4440 * Fixed INFO command in the server. It works now in router
4441 environment. Added <server name> argument to the INFO command
4442 reply. Updated the protocol specs.
4444 * Fixed minor bug in silc_idcache_purge to not purge if the
4445 expire value is zero.
4447 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4448 they were buggy because of the WHOWAS information.
4450 * Fixed local command MSG to handle the async resolving of
4451 the remote client properly. It used to fail the first MSG.
4452 Affected file silc/local_command.c.
4454 * Added `data_len' field to SilcIDCache context.
4456 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4458 * Update TODO. Todo in commands in the server.
4460 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4462 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4463 used by routers as broadcast packet to inform other routers
4464 about the changed user mode.
4466 Implemented the notify handling in the server. Affected file is
4467 silcd/packet_receive.c. Added the function
4468 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4470 * Added new generic Channel Payload and deprecated the New Channel
4471 Payload. The New Channel Payload is now the generic Channel
4474 * Added new argument `mode' to the silc_server_send_new_channel
4475 as it is required in the Channel Payload now.
4477 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4478 and created a new and real SilChannelPayload to represent the
4479 new generic Channel Payload. Implemented the encode/decode
4480 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4482 * Added silc_server_get_client_channel_list to return the list
4483 of channels the client has joined for WHOIS command reply.
4484 Affected file silcd/server.[ch].
4486 * Implemented the channel list sending in the WHOIS command reply
4487 in server and in the client.
4489 Implemented the channel list displaying on the user interface
4490 as well. Affected file silc/client_ops.c.
4492 * Added silc_channel_payload_parse_list to parse list of Channel
4493 Payloads. It returns SilcDList list of SilcChannelPayloads.
4494 Client for example can use this function to parse the list of
4495 channels it receives in the WHOIS command reply. The caller
4496 must free the list by calling silc_channel_payload_list_free.
4497 Affected files lib/silccore/silcchannel.[ch].
4499 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4501 * Added one new argument <user mode> to the WHOIS command reply
4502 to return the mode of the user in SILC. Updated the protocol
4505 Implemented it to the server and client.
4507 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4509 * Fixed the mode printing on the user interface on joining.
4510 Affected file silc/client_ops.c.
4512 * Implemented the UMODE command and user modes in general to the
4513 client library and to the user interface.
4515 * Implemented the UMODE command to the server.
4517 * The server now sends UNKNOWN_COMMAND error status if client sends
4518 unknown command. Affected file silcd/command.c.
4520 * All server commands now handle the command identifier the right
4521 way when sending the command reply to the client. The client can
4522 use to identify the command replies with the identifier.
4524 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4526 * Added silc_server_get_client_route to resolve the route to
4527 the client indicated by the client ID. Affected file is
4530 * Added silc_server_relay_packet as general function to relay
4531 packet to arbitrary destination. This deprecates functions
4532 like _send_private_message_key, _relay_notify etc. Affected
4533 file is silcd/packet_send.[ch].
4535 Removed silc_server_send_key_agreement,
4536 silc_server_send_private_message_key and
4537 silc_server_packet_relay_notify functions from the file
4538 silcd/packet_send.[ch].
4542 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4543 server. Affected file silcd/packet_receive.[ch].
4545 * Implemented the KILL command to the client. Implemented the
4546 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4547 Affected files lib/silcclient/command[_reply].c and
4548 lib/silcclient/client_notify.c. Implemented the KILL notify
4549 printing in the user inteface.
4551 * Fixed a lot silc_parse_nick memory leaks from the client
4552 library in the file lib/silcclient/command.c.
4554 * Changed the silc_server_send_notify_on_channels's `sender'
4555 argument from SilcSocketConnection to SilcClientEntry to
4556 check the sender as entry and not as connection object and not
4557 to send to the client provided as argument. The affected file
4558 is silcd/packet_send.[ch].
4560 * The notify packets that are destined directly to the client used
4561 to not to be processed by the server. Now changed that and the
4562 server processes all notify packets. After relaying the packet
4563 to the client the notify packet is processed in the server.
4565 * The silc_server_free_client_data now checks whether there is
4566 pending outgoing traffic for the client and purges the data to
4567 the network before removing the client entry.
4569 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4571 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4572 an client is killed from the SILC Network. Updated the protocol
4575 Added new function silc_server_send_notify_killed to the
4576 silcd/packet_send.[ch].
4578 * Added function silc_server_packet_relay_notify to relay notify
4579 packets that are destined directly to a client. In this case
4580 the server does not process the notify packets but merely relays
4581 it to the client. Affected file silcd/packet_send.[ch].
4583 Added also silc_server_packet_process_relay_notify to check
4584 whereto relay the notify. Affected file is
4585 silcd/packet_receive.[ch].
4587 * Implemented the KILL command to the server.
4591 * Added the backup schema desgined last fall to the protocol
4592 specs for everyone to see. The specification is in the
4593 *-spec-xx.txt draft and the packet type definitions for the
4594 backup routers is in *-pp-xx.txt draft. Thusly, added also
4595 new packet type SILC_PACKET_CELL_ROUTERS.
4597 * A big security problem in the implementation discovered. The
4598 signoff of an client did not cause new channel key generation
4599 which it of course should've done. The channel keys must be
4600 always re-generated when client leaves (or signoffs) the channel.
4601 The silc_server_remove_from_channels funtion now handles
4602 the channel key re-generation.
4604 * Added `sender' argument to the silc_server_send_notify_on_channels
4605 to not to send the client provided as argument. Affected file
4606 silcd/packet_send.[ch].
4608 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4610 * Implemented OPER and SILCOPER commands into the server and
4613 * Added silc_auth_verify and silc_auth_verify_data to verify
4614 the authentication directly from the authentication payload.
4615 It supports verifying both passphrase and public key based
4616 authentication. Affected file lib/silccore/silcauth.[ch].
4618 * Added `hash' field to the SilcIDListData structure. It is the
4619 hash negotiated in the SKE protocol. Affected file is
4622 * Slight redesigning of the SilcAuthPayload handling routines.
4623 Do not send SilcPKCS but SilcPublicKey as argument.
4625 * Implemented the public key authentication support to the
4626 serverconfig. The public key is loaded from the provided path
4627 and saved as authentication data to void * pointer. Thus,
4628 changed the unsigned char *auth_data to void *auth_data;
4630 * Fixed SHUTDOWN command to send the reply before the server
4631 is shutdown. :) Affected file silcd/command.c.
4633 * Fixed fatal bug in CONNECT command. The hostname was invalid
4634 memory and server crashed. Affected file silcd/command.c.
4636 * Fixed fatal bug in CLOSE command. The server_entry became
4637 invalid but was referenced later in the command. Affected file
4640 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * Fixed fatal bug in failure packet handling. Server ignored
4643 the failure and thus crashed when it came.
4647 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4649 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4650 that the command may be executed only once in (about) 2 seconds.
4651 The old SILC_CF_LAG flag is same but allows command bursts up
4652 to five before limiting.
4654 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4655 server code. Various commands now includes the CF_LAG_STRICT
4656 flag to disallow any kind of miss-use of the command.
4658 * Fixed the silc_buffer_unformat to not to allocate any data
4659 if the length of the data is zero. It used to allocate the
4660 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4662 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4664 * Changed the format of AdminConnection configuration section
4665 in the server. Added username of the admin to the format.
4666 Affected files silcd/serverconfig.[ch].
4668 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4669 to return admin configuration data by host, username and/or
4672 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4674 * Implemented WHOWAS command to the server. Added the functions:
4676 silc_server_command_whowas_parse,
4677 silc_server_command_whowas_send_reply,
4678 silc_server_command_whowas_from_client and
4679 silc_server_command_whowas_from_server
4681 * Added <Client ID> argument to the WHOWAS command reply. Updated
4682 the protocol specs accordingly.
4684 * Implemented WHOWAS command and command_reply to the client
4687 Implemented the WHOWAS printing on the user interface.
4689 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4691 * Added new argument to the WHOWAS command reply, the real name.
4692 It is an optional argument. Updated the protocol specs.
4694 * Added SilcIDCacheDestructor callback that is registered when
4695 the SilcIDCache is allocated. The callback is called when
4696 an cache entry in the ID Cache expires, or is purged from the
4697 cache. Added into lib/silccore/idcache.[ch].
4699 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4700 to destruct the client entries when the cache entry expires.
4701 Other ID Cache's in server and in the client library ignores
4704 * If the ID Cache entry's `expire' field is zero then the entry
4705 never expires. Added boolean `expire' argument to the
4706 silc_idcache_add function in the lib/silccore/idcache.[ch].
4707 If it is TRUE the default expiry value is used.
4709 * Added silc_server_free_client_data_timeout that is registered
4710 when client disconnects. By default for 5 minutes we preserve
4711 the client entry for history - for WHOWAS command.
4713 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4715 * Added support to the server to enforce that commands are not
4716 executed more than once in 2 seconds. If server receives
4717 commands from client more frequently, timeout is registered
4718 to process the commands. Affected file silcd/command.c.
4719 Added new function silc_server_command_process_timeout.
4721 * Changed NICK_NOTIFY handling in client library to check that
4722 if the client's nickname was changed, so there is no need to
4723 resolve anything from the server.
4725 * Removed error printing from the WHOIS and IDENTIFY commands.
4726 If error occurs then it is ignored silently in the client library.
4727 The application, however, may map the received error to
4728 human readable error string. The application currently maps
4729 the NO_SUCH_NICKNAME error to string.
4731 * Made the command status message public to the application. Moved
4732 them from lib/silcclient/command_reply.c to
4733 lib/silcclient/command_reply.h. The application can map the
4734 received command status to the string with the
4735 silc_client_command_status_message function.
4737 * Added check to the server to check that client's ID is same
4738 as the Source ID in the packet the client sent. They must
4741 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4743 * Added dist-bzip hook to the Makefile.am to make bzip2
4744 compressed distributions.
4746 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4748 * Server now enforces the maximum length for the nickname and
4749 the channel as protocol specification dictates. 128 bytes for
4750 nickname and 256 bytes for channel name.
4752 * Moved the WHOIS printing to the application. The client libary
4753 does not print out the WHOIS information anymore, the application
4754 must do it. Renamed silc_client_command_reply_whois_print to
4755 the silc_client_command_reply_whois_save.
4757 The client's idle time is also sent to the application now, and
4758 the idle is shown on screen.
4760 * Added silc_client_command_reply_identify_save to save the
4761 received IDENTIFY entries.
4763 * Do not check for channel private keys in message sending and
4764 reception if the channel does not have the PRIVKEY mode set.
4765 Affected file lib/silclient/client_channel.c.
4767 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4769 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4770 just surfaced after chaning the JOIN procedure.
4772 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4774 * Added silc_client_get_clients_by_list to get client entries
4775 from Client ID list, that is returned for example by JOIN
4776 and USERS command replies. The application should use this
4777 function for example when JOIN command reply is received to
4778 resolve the clients already on the channel (library does not
4779 do that anymore as USERS command reply is not used in the JOIN
4780 procedure anymore). Affected files lib/silcclient/silcapi.h and
4781 lib/silcclient/idlist.c.
4783 * JOIN command reply and USERS command reply returns now SilcBuffer
4784 pointers instead of unsigned char pointers when returning
4785 the client list and mode list.
4787 * Added <Client ID> argument to the JOIN command reply, mainly
4788 for the server to identify for which client the command was
4789 originally sent. Updated protocol specs accordingly.
4791 * Added SilcDlist private_key pointer to the SilcChannelEntry
4792 in the client to support the channel private keys. Affected
4793 file is lib/silcclient/idlist.h.
4795 * Added SilcChannelPrivateKey argument to the function
4796 silc_client_send_channel_message so that application can choose
4797 to use specific private ke if it wants to. If it is not provided,
4798 the normal channel key is used, unless private keys are set.
4799 In this case the first (key that was added first) is used
4800 as the encryption key.
4802 * Implemented the support for channel private key handling.
4803 Implemented the following functions:
4805 silc_client_add_channel_private_key,
4806 silc_client_del_channel_private_keys,
4807 silc_client_del_channel_private_key,
4808 silc_client_list_channel_private_keys and
4809 silc_client_free_channel_private_keys
4811 Affected file lib/silcclient/client_channel.c.
4813 * Added the support for the private keys in the channel message
4814 sending and encryption and in the message reception and
4815 decryption. Affected funtions are
4816 silc_client_send_channel_message and silc_client_channel_message.
4818 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4820 * Added SKE's key verify callback to the client library's
4821 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4823 * Removed the statement that server (or router) must send USERS
4824 command reply when joining to the channel so that the client
4825 knows who are on the channel. Instead, the client list and
4826 client's mode list is now sent in the JOIN command reply to the
4827 client who joined channel. This is better solution.
4829 * Added function silc_server_get_users_on_channel and function
4830 silc_server_save_users_on_channel to the silcd/server.[ch].
4832 * Removed function silc_server_command_send_users from the
4835 * Do not show topic on the client library anymore. The topic is
4836 sent in the command reply notify to the application and the
4837 application must show the topic now.
4839 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4841 * Added client searching by nickname hash into the IDENTIFY and
4842 WHOIS commands in the server as they were clearly missing from
4843 them. Affected file is silcd/command.c.
4845 * Fixed a bug in private message receiving in the client library.
4846 The remote ID was freed and it wasn't supposed, now it is
4849 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4851 * Minor fix to the channel payload; allocate the data area, as it
4852 needs to be of specific length.
4854 * If the key agreement port is zero then the operating
4855 system will define the bound port. Affected files are
4856 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4858 * Added new function silc_channel_payload_decrypt into the file
4859 lib/silccore/silcchannel.[ch].
4861 * Moved the channel message etc, check from silc_packet_decrypt
4862 to applications. The library calls now a generic
4863 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4864 when the packet is either normal or special. This was done to
4865 allow more wide range of checking that was not allowed when
4866 the code was in library. Now applications can do virtually any
4867 checks to the packet and return to the library the decision how
4868 the packet should be processed. Affected files are
4869 lib/silccore/silcpacket.[ch].
4871 Added silc_server_packet_decrypt_check to the server and
4872 silc_client_packet_decrypt_check to the client library.
4874 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4875 to send with specified source and destination information.
4877 * Channel message delivery between routers was broken after the
4878 channel key distribution was fixed earlier. The channel key
4879 was used be to distributed to other routers as well which is not
4880 allowed by the protocol. Now this is fixed and channel keys
4881 really are cell specific and the channel message delivery between
4882 routers comply with the protocol specification.
4884 * Fixed various commands in server to check also the global list
4885 for the channel entry and not just the local list. The affected
4886 file silcd/command.c.
4888 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4890 * Added assert()s to buffer formatting and unformatting routines
4891 to assert (if --enable-debug) when error occurs. Affected
4892 file: lib/silcutil/silcbuffmt.c.
4894 * Changed to auto-reconnect to check whether the remote host is
4895 router and register the re-connect timeout if it is. It used
4896 to check that whether we are normal server, but router must do
4897 auto-reconnect with another router as well. Affected file
4900 * Removed the [<key len>] option from CMODE command as the cipher
4901 name decides the key length, nowadays. See the defined ciphers
4902 from the protocol specification.
4904 * Added [<hmac>] option to the CMODE command to define the HMAC
4905 for the channel. Added SILC_CMODE_HMAC channel mode.
4907 * Added [<hmac>] option for the JOIN command so that user can
4908 select which HMAC is used to compute the MACs of the channel
4911 * Added Hmac field to the Channel Message Payload. The integrity
4912 of plaintext channel messages are now protected by computing
4913 MAC of the message and attaching the MAC to the payload. The
4914 MAC is encrypted. Now, it is clear that this causes some
4915 overhead to the size of the packet but rationale for this is that
4916 now the receiver can verify whether the channel message decrypted
4917 correctly and also when private keys are set for the channel the
4918 receiver can decrypt the packet with several keys and check from
4919 the MAC which key decrypted the message correctly.
4921 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4922 lib/silccrypt/silccipher.[ch].
4924 * Added silc_hash_len to return the digest length into the
4925 lib/silcrypt/silchash.[ch].
4927 * Rewrote parts of Silc Channel Payload interface in the
4928 lib/silccore/silcchannel.[ch]. The encode function now also
4929 encrypts the packet and parse function decrypts it.
4931 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4933 * Fixed a minor formatting bug in the SKE's key material processing.
4934 It actually might have processed the keys wrong way resulting
4937 * Redefined the mandatory HMAC algorithms and added new algorithms.
4938 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4939 and hmac-md5 truncated to 96 bits. The mandatory is now
4940 hmac-sha1-96. Rest are optional (including the one that used
4941 to be mandatory). Rationale for this is that the truncated HMAC
4942 length is sufficient from security point of view and can actually
4943 make the attack against the HMAC harder. Also, the truncated
4944 HMAC causes less overhead to the packets. See the RFC2104 for
4947 * Added new [hmac] configuration section. The SKE used to use
4948 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4949 is of course wrong. The official names that must be proposed in
4950 the SKE are the ones defined in the protocol specification
4951 (hmac-sha1-96 for example). The user can configure any hmac
4952 using any hash function configured in the [hash] section. At
4953 least, the mandatory must be configured.
4955 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4957 * Added HMAC list to the SKE proposal list. It has now both
4958 hash algorithm list and HMAC list. This makes the protocol
4959 incompatible with previous versions. The SKE now seems to work
4960 the way it is supposed to work, for the first time actually.
4962 * Defined plain Hash algorithms to the protocol specification.
4965 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4967 * Implemented support for key agreement packets into the server.
4968 Added functions silc_server_key_agreement and
4969 silc_server_send_key_agreement. Other than these functions,
4970 server has nothing to do with this packet.
4972 * Added support for private message key packets into the server.
4973 Added functions silc_server_private_message_key and
4974 silc_server_send_private_message_key.
4978 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4979 called in the protocol's final callback instead in the END
4980 protocol state. This makes a little more sense and in the same
4981 time in client we can use the same protocol routines for normal
4982 key exchange and to key agreement packet handling as well.
4984 * Added to both client's and server's KE protocol context the
4985 SilcSKEKeyMaterial pointer to save the key material. We will
4986 bring the key material to the protocol's final callback by doing
4987 this. The final callback must free the key material.
4989 * Added SKE's packet_send callback into client's KE protocol
4990 context so that the caller can choose what packet sending function
4991 is used. This way we can use different packet sending when
4992 doing normal SKE when doing key agreement packet handling (in
4993 the key agreement packet handling we do not want to encrypt
4996 * Implemented the responder side of the key agreement routines
4997 in the client. The client can now bind to specified port and
4998 accept incoming key negotiation. The key material is passed
4999 to the application after the protocol is over.
5001 * Implemented the processing of incoming Key Agreement packet
5002 in the client. Added function silc_client_key_agreement to
5005 * Implemented the intiator side of the key agreement routines
5006 in the client. The client can now initiate key agreement with
5007 another remote client. The key material is passed to the
5008 application after the protocol is over.
5010 * Created client_keyagr.c to include all the key agreement
5013 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5014 SILC_TASK_CALLBACK except that it is not static.
5016 * Created client_notify.c and moved the Notify packet handling
5017 from the client.[ch] into that file.
5019 * Created client_prvmsg.c and moved all private message and
5020 private message key routines from the client.[ch] into that file.
5022 * Create client_channel.c and moved all channel message and
5023 channel private key routines from the client.[ch] into that file.
5025 * Changed silc_client_get_client_by_id_resolve to resolve with
5026 WHOIS command instead of IDENTIFY command, in the file
5027 lib/silclient/idlist.c.
5029 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5031 * Implemented the SKE's responder side to the Client library.
5033 * When FAILURE is received to the protocol do not trust it
5034 blindly. Register a timeout to wait whether the remote closes
5035 the connection as it should do it, only after that process the
5036 actual failure. This was changed to both client and server.
5038 * Added client_internal.h to include some of the structures
5039 there instead of client.h in lib/silcclient/.
5041 * Added function silc_task_unregister_by_callback to unregister
5042 timeouts by the callback function.
5044 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Some "Incomplete WHOIS info" errors has been appearing on the
5047 log files. Took away the entry->userinfo check from WHOIS
5048 reply sending. The entry->userinfo is now " " if client did not
5049 provide one. I thought this was fixed earlier but something
5050 is wrong still. Let's see if the error still appears.
5052 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5054 * Fixed a minor bug in the login when the channel key is
5055 re-generated in the server. It used to generate the key in
5056 wrong order and thus caused problems in the channel traffic.
5058 * Fixed a minor bug in channel key distsribution after
5059 KICK command. The key was not sent to the router even though
5062 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Added silc_ske_process_key_material_data as generic routine
5065 to process any key material as the SILC protocol dictates. The
5066 function is used by the actual SKE library but can be used by
5067 applications as well. This relates to the private message keys
5068 and the channel private keys since they must be processed the
5069 same way the normal SILC session keys. The protocol dictates
5070 this. Affected files: lib/silcske/silcske.[ch].
5072 Added also silc_ske_free_key_material to free the
5073 SilcSKEKeyMaterial structure.
5075 * Defined silc_cipher_set_key function to set the key for
5076 cipher without using the object's method function. The affected
5077 files: lib/silccrypt/silccipher.[ch].
5079 * Implemented silc silc_client_add_private_message_key,
5080 silc_client_add_private_message_key_ske,
5081 silc_client_del_private_message_key,
5082 silc_client_list_private_message_keys and
5083 silc_client_free_private_message_keys functions in the
5086 Added functions silc_client_send_private_message_key to send
5087 the Private Message Key payload and silc_client_private_message_key
5088 to handle incoming Private Message Key payload.
5090 * Added Cipher field to the Private Message Key payload to set
5091 the cipher to be used. If ignored, the default cipher defined
5092 in the SILC protocol (aes-256-cbc) is used.
5094 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5096 * Removed lib/silcclient/ops.h file.
5098 Redefined parts of the SILC Client Library API. Created new
5099 file silcapi.h that deprecates the ops.h file and defines the
5100 published Client Library API. Defined also private message key
5101 API and channel private key API into the file.
5103 This is the file that the application must include from the
5104 SILC Client Library. Other files need not be included by
5105 the application anymore.
5107 * Added new key_agreement client operation callback and also
5108 defined the Key Agreement library API for the application.
5110 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5113 is used by clients to request key negotiation between another
5114 client in the SILC network. If the negotiation is started it
5115 is performed using the SKE protocol. The result of the
5116 negotiation, the secret key material, can be used for example
5117 as private message key.
5119 Implemented the Key Agreement payload into the files
5120 lib/silccore/silauth.[ch].
5122 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5124 * Redefined ciphers for the SILC protocol. Added some new ciphers
5125 and defined the key lengths for the algorithms. Changed the
5126 code accordingly. The default key length is now 256 bits.
5128 * Fixed SKE key distribution function silc_ske_process_key_material
5129 when the key length is more than 128 bits. The default key
5130 length in SILC is now 256 bits.
5132 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5133 to indicate unsupported algorithm.
5135 * Renamed rijndael.c to aes.c and all functions as well.
5137 * Fixed a long standing channel key setting bug in client library.
5138 Weird that it has never surfaced before.
5140 * Fixed bug in channel deletion. If the entire channel is removed
5141 then it must also delete the references of the channel entry
5142 from the client's channel list as the client's channel entry and
5143 the channel's client entry share same memory.
5145 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5147 * Implemented CONNECT and SHUTDOWN commands in the client.
5149 * Implemented CLOSE command to the client.
5151 * Added the function silc_idlist_find_server_by_name into the
5152 files silcd/idlist.[ch].
5154 Added the function silc_idlist_find_server_by_conn into the
5155 files silcd/idlist.[ch].
5157 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * DIE command was renamed to SHUTDOWN. Updated the both code
5162 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5163 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5165 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5168 * Added function silc_server_create_connection function to create
5169 connection to remote router. My server implementation actually
5170 does not allow router to connect to normal server (it expects
5171 that normal server always initiates the connection to the router)
5172 so the CONNECT command is only good for connecting to another
5175 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5177 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5178 or some other client was kicked from the channel.
5180 Implemented the handling of the notify type to both client
5183 Implemented silc_server_send_notify_kicked to send the KICKED
5184 notify. It is used to send it to the server's primary router.
5186 * Implemented the KICK command into server and client.
5188 * Added `query' argument to the silc_idlist_get_client function
5189 to indicate whether to query the client from server or not if
5192 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5193 to indicate that the client is not channel founder.
5197 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5199 * Removed the rng context from SilcPacketContext structure and
5200 changed that the packet routine uses the Global RNG API.
5202 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5204 * Added support for quit message that client can "leave" on the
5205 channel when it quits the SILC. It is ditributed inside the
5206 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5208 Added silc_server_free_client_data that will take the
5209 signoff message as argument.
5211 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5213 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5215 * Updated parts of the protocol specification to keep it up
5218 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5221 payloads in one packet.
5223 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5224 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5225 use now the new List flag.
5227 * Also deprecated the following packet types: REPLACE_ID,
5228 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5230 * Added list support for Notify packet in server.
5232 * Added silc_server_send_notify_channel_change to send the
5233 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5234 the silc_server_send_replace_id.
5236 * Added silc_server_send_notify_nick_change to send the
5237 NICK_CHANGE notify type. Deprecates the function
5238 silc_server_send_replace_id.
5240 * Added silc_server_send_notify_join to send the JOIN notify type.
5241 Deprecates the function silc_server_send_new_channel_user.
5243 * Added silc_server_send_notify_leave to send LEAVE notify type.
5244 Deprecates the function silc_server_send_remove_channel_user.
5246 * Added silc_server_send_notify_cmode and
5247 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5248 types. Deprecates the silc_server_send_set_mode function.
5250 * Added SERVER_SIGNOFF notify type to indicate that server has
5251 quit. This means that all clients on the channel from that
5252 server will drop. This can be also used when netsplit happens.
5254 Deprecated REMOVE_ID packet type since it is not needed anymore
5257 Added silc_server_send_notify_server_signoff to send the
5258 SERVER_SIGNOFF notify type. Deprecates the function
5259 silc_server_send_remove_id.
5261 Added also silc_server_send_notify_signoff to send the
5262 SIGNOFF notify type.
5264 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5265 SILC protocol from this day on. Changed the protocol
5266 specification as well.
5268 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5269 notify type. It is used between routers to notify about
5270 topic changes on a channel.
5272 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5275 * Partly updated the protocol specification to comply with the
5276 changes now made. It is still though a bit outdated.
5278 * The JOIN notify type now takes one extra argument <Channel ID>.
5279 The packet used to be destined to the channel but now the
5280 JOIN type may be sent as list thus it is impossible to
5281 destine it to any specific channel. By adding this argument
5282 it is again possible.
5284 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5286 * Added CREDITS file. The CHANGES and CREDITS file will appear
5287 in the distribution as well.
5289 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5291 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5292 types in the server's silcd/packet_receive.c.
5294 * Implemented CMODE and CUMODE to work in router environment.
5296 * Fixed minor encoding and decoding buglet from the
5297 lib/silccore/silcmode.c.
5299 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5302 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5304 * Changed all SilcConfigServer* and silc_config_server* to
5305 SilcServerConfig* and silc_server_config*, respectively.
5308 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5310 * Associated the ID (client or server ID) to the Authentication
5311 Payload to avoid any possibility of forging. Updated the
5312 protocol specification and the code accordingly.
5314 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * The RSA key length is now save to the RsaKey context in the
5317 key generation process in lib/silccrypt/rsa.c. The key length
5318 is now used to figure out the maximum size of the block allowed
5319 to be encrypted/signed.
5321 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5322 is equivalent to the silc_mp_mp2bin but does not allocate any
5325 * Changed silc_mp_mp2bin API to take length argument. If it is
5326 non-zero then the buffer is allocated that large. If zero, then
5327 the size is approximated using silc_mp_sizeinbase, which however
5330 * Created Global RNG API which is global RNG that application can
5331 initialize. After initializing, any routine anywhere in the
5332 code (including library) can use RNG without allocating a new
5333 RNG object. This was done to allow this sort of use of the
5334 RNG in code that has no chance to allocate RNG object. All
5335 applications currently allocate this and many routines in the
5336 library use this. Affected file lib/silccrypt/silcrng.[ch].
5338 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5339 it to use the Global RNG API.
5341 * Defined Authentication Payload into protocol specification that
5342 is used during SILC session to authenticate entities. It is
5343 used for example by client to authenticate itself to the server
5344 to obtain server operator privileges.
5346 Implemented this payload into the lib/silccore/silcauth.[ch].
5347 Implemented also routines for public key based authentication
5348 as the new protocol specification dictates.
5350 Moved definitions of different authentication methods from
5351 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5353 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5354 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5355 silc_pkcs_verify_with_hash functions into the file
5356 lib/silccrypt/silcpkcs.[ch].
5358 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5360 * The client entry's userinfo pointer must be always valid.
5361 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5362 will fail since it requires the userinfo. Now, the userinfo
5363 is allocated as "" if actual userinfo does not exist. Actually,
5364 it must exist and it is totally Ok to drop client connections
5365 that does not announce the userinfo. However, we will make
5366 this workaround for now.
5368 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5369 to return the remote port by socket.
5371 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5373 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5374 SILC_SERVER_PENDING_EXEC and added an new macro
5375 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5376 data or when error occurs while processing the pending command.
5378 Added new argument `destructor' into silc_server_command_pending
5379 and to the SilcServerCommandPending object. This destructor is
5380 now called after calling the pending callback or if error occurs
5381 immediately. If error occurs the actual pending callback won't
5382 be called at all - only the destructor. The destructor may be
5383 NULL if destructor is not needed.
5385 All this applies for client library code as well. Similar
5386 changes were made there as well for the pending commands.
5388 In the client, the application must now allocate the
5389 SilcClientCommandContext with the silc_client_command_alloc
5392 * Added reference counter to the SilcServerCommandContext. Added
5393 function silc_server_command_alloc and silc_server_command_dup
5396 Same type of functions added to the client library for the same
5399 * Removed the cmd_ident from IDListData away since it is now
5400 global for all connections. It is the command identifier used
5401 in command sending and with pending commands. The affected file
5404 * Added reference counter to the SilcSocketConnection objecet to
5405 indicate the usage count of the object. The object won't be
5406 freed untill the reference counter hits zero. Currently only
5407 server uses this, and client ignores it. The client must be
5408 set to use this too later. The affected files are
5409 lib/silccore/silcsockconn.[ch]. Added also the function
5410 silc_socket_dup to increase the reference counter.
5412 This was mainly added because it is possible that the socket
5413 is removed underneath of pending command or other async
5414 operation. Now it won't be free'd and proper DISCONNECTING
5415 flags, etc. can be set to avoid sending data to connection that
5416 is not valid anymore.
5418 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5419 the connection. After that it sets SILC_SET_DISCONNECTED.
5420 It is, however, possible that the socket data is not still freed.
5421 The silc_server_packet_process now checks that data is not
5422 read or written to connection that is DISCONNECTED. The socket
5423 get's freed when the reference counter hits zero.
5425 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5427 * Changed the client operation API: channel_message operation's
5428 `sender' is now the client entry of the sender, not the nickname
5429 and the `channel' is the channel entry, not the channel name.
5431 In the private_message operation the `sender' is now also the
5432 client entry of the sender not the nickname.
5434 Affected file is lib/silcclient/ops.h and all applications
5435 using the client operations.
5437 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5439 * Moved the calling of ops->connect() from connect_to_server_final
5440 into receive_new_id functin since that is the point when the
5441 client is actually allowed to send traffic to network. The
5442 affected file is lib/silcclient/client.c.
5444 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5446 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5447 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5448 (if needs broadcasting) instead of broadcasting the packets one
5449 by one which would make a burst in the network traffic.
5451 * Added `broadcast' argument to the functions in silcd/server.[ch]
5452 silc_server_create_new_channel[_with_id] to indicate whether
5453 to send New Channel packet to primary router.
5455 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Added new function into the silcd/server.[ch] files:
5458 silc_server_create_new_channel_with_id to create new channel with
5459 already existing Channel ID.
5461 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5462 lib/silccore/silcpacket.h. This packet is used t send list of
5463 Set Mode payloads inside one packet. Server uses this to set
5464 the modes for the channels and clients on those channels, that it
5465 announced to the router when it connected to it. The protocol
5466 specification has been updated accordingly.
5468 * The silc_server_new_channel did not handle the packet coming
5469 from normal server as it normally does not send that. However,
5470 when it announces its channels it does send it. Implemented
5471 the support for that.
5473 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5474 into the file lib/silccore/id.h.
5476 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * Fixed memory leaks in the functions silc_idlist_del_client,
5479 silc_idlist_del_channel and silc_idlist_del_server in the file
5480 silcd/idlist.c. All of those leaked like a sieve.
5482 * Fixed some small memory leaks in the client's function
5483 silc_client_notify_by_server.
5485 * Added functions into silcd/server.c: silc_server_announce_clients,
5486 silc_server_announce_channels and silc_server_announce_server.
5487 These functions are used by normal and router server to announce
5488 to its primary router about clients, channels and servers (when
5489 router) that we own. This is done after we've connected to the
5492 These functions effectively implements the following packet types:
5493 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5494 and SILC_PACKET_NEW_ID_LIST.
5496 * Added new functions into the silcd/packet_receive.[ch]:
5497 silc_server_new_id_list, silc_server_new_channel_list and
5498 silc_server_new_channel_user_list to handle the incoming
5499 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5501 * Added support of changing Channel ID in the function
5502 silc_server_replace_id. If the server that announces a channel
5503 to the router already exists in the router (with same name but
5504 with different Channel ID), router is responsible to send
5505 Replace ID packet to the server and force the server to change
5506 the Channel ID to the one router has.
5508 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5509 client that the Channel ID has been changed by the router. The
5510 normal server sends this to the client. Client must start using
5511 the new Channel ID as the channel's ID.
5513 Implemented handling of this new type into lib/silcclient/client.c
5514 into the function silc_client_notify_by_server.
5516 * Added new function silc_idlist_replace_channel_id into the files
5517 silcd/idlist.[ch] to replace the Channel ID.
5519 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5521 * Call silc_server_command_identify_check always when processing
5522 the IDENTIFY command in silcd/command.c
5524 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5526 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5527 send keepalive packets. The packet can be sent by clients,
5528 servers and routers.
5530 Added function silc_socket_set_heartbeat into the file
5531 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5532 If not set, the heartbeat is not performed. The actual
5533 heartbeat is implemented in the low level socket connection
5534 library. However, application is responsible of actually
5537 Added silc_server_send_heartbeat to send the actual heartbeat
5538 packet into silcd/packet_send.[ch]. Server now performs
5539 keepalive with all connections.
5541 * Added silc_task_get_first function into lib/silcutil/silctask.c
5542 to return the timeout task with shortest timeout. There was a bug
5543 in task unregistration that caused problems. TODO has been
5544 updated to include that task system must be rewritten.
5546 * The client library will now resolve the client information when
5547 receiving JOIN notify from server for client that we know but
5548 have incomplete information.
5550 * Rewrote parts of silc_server_remove_from_channels and
5551 silc_server_remove_from_one_channel as they did not remove the
5552 channel in some circumstances even though they should've.
5554 * Encryption problem encountered in server:
5556 The LEAVE command used to send the Channel Key packet to the
5557 router immediately after generating it. However, the code
5558 had earlier sent Remove Channel user packet but not immediately,
5559 ie. it was put to queue. The order of packets in the router
5560 was that Channel Key packet was first and Remove Channel User
5561 packet was second, even though they were encrypted in the
5562 reverse order. For this reason, MAC check failed. Now, this
5563 is fixed by not sending the Channel Key packet immediately but
5564 putting it to queue. However, this is more fundamental problem:
5565 packets that are in queue should actually not be encrypted
5566 because packets that are sent immediately gets encrypted
5567 actually with wrong IV (and thus MAC check fails). So, packets
5568 that are in queue should be encrypted when they are sent to
5569 the wire and not when they put to the queue.
5571 However, the problem is that the current system has not been
5572 designed to work that way. Instead, the packet is encrypted
5573 as soon as possible and left to the queue. The queue is then
5574 just purged into wire. There won't be any fixes for this
5575 any time soon. So, the current semantic for packet sending
5578 o If you send packet to remote host and do not force the send
5579 (the packet will be in queue) then all subsequent packets to the
5580 same remote host must also be put to the queue. Only after the
5581 queue has been purged is it safe again to force the packet
5584 o If you send all packets immediately then it safe to send
5585 any of subsequent packets through the queue, however, after
5586 the first packet is put to queue then any subsequent packets
5587 must also be put to the queue.
5589 Follow these rules and everything works fine.
5591 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5593 * Added new function silc_server_remove_clients_by_server to
5594 remove all client entries from ID list when the server connection
5595 is lost. In this case it is also important to invalidate all
5596 client entires as they hold the invalid server entry. This
5597 fixes fatal bug when server has lost connection and will reconnect
5600 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Made some sanity checks to silc_server_daemonise like to check
5603 whether the requested user and group actually exists.
5605 * Added sanity check to SKE's silc_ske_responder_finish to check
5606 that the public and private key actually is valid.
5608 * Invalidate the client's nickname when receiving Replace ID
5609 packet and the Client ID is being replaced. This means that the
5610 server will query the nickname if someone needs it (client)
5613 * Sort the ID Cache in client library when the ID Cache data
5614 has changed (needs sorting).
5616 * Do not allow for SILC client to create several connections to
5617 several servers. The client does not support windows right now
5618 and generating multiple connections causes weird behaviour.
5620 Irssi-silc client does support windows and can handle several
5621 connections without problems, see: www.irssi.org and SILC plugin.
5623 * Fixed some places where client was added to the IDList. The
5624 rule of thumb is following (in order to get everything right):
5625 If the client is directly connected local client then the
5626 `connection' argument must be set and `router' argument must be
5627 NULL to silc_idlist_add_client function. If the client is not
5628 directly connected client then the `router' argument must
5629 bet set and the `connection' argument must be NULL to the
5630 silc_idlist_add_client function.
5632 * The funtion silc_server_packet_send_local_channel actually did
5633 not check whether the client was locally connected or not. It
5634 does that now. Fixed a bug related to LEAVE command.
5636 * Fixed Remove Channel User payload parsing bug in server's
5637 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5639 * The server's silc_server_save_channel_key now checks also the
5640 global ID list for the channel as it might not be in the local
5641 list. Fixed a bug related to LEAVE command.
5643 * Is this the end of the [<unknown>] buglet that has been lurking
5644 around for a long time? A little for loop fix in server's
5645 silc_server_command_whois_parse that is used by both IDENTIFY
5646 and WHOIS command. At least, this was a clear bug and a cause
5647 of one type of [<unknown>] buglet.
5649 * WHOIS and IDENTIFY commands call the function
5650 silc_server_command_[whois/identify]_check function even if
5651 we are not router server.
5653 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5655 * Added --with-gmp configuration option. If set the GMP
5656 is always compiled in the SILC source tree. If not set then
5657 it is checked whether the system has the GMP3 installed. If
5658 it has then the GMP won't be compiled (the system's headers
5659 and library is used), if it doesn't have it then the GMP is
5660 compiled in the SILC source tree.
5662 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5664 * Changed RSA private exponent generation to what PKCS #1
5665 suggests. We try to find the smallest possible d by doing
5666 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5667 not security fix but optimization.
5669 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5671 * Added new config entry [Identity] to fork the server and run
5672 it as specific user and group. A patch from Bostik.
5674 * Imported Dotconf configuration library into lib/dotconf.
5675 This will be used to create the SILC configuration files later.
5676 It will appear in the distsribution after this commit.
5678 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5680 * A big code auditing weekend happening. Auditing code for
5681 obvious mistakes, bugs and errors. Also, removing any code
5684 Removed files for being obsolete:
5686 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5687 inline in the file lib/silcutil/silcbuffer.h)
5689 o lib/silcutil/silcbufutil.c (the header has inline versions)
5691 Changed code to fix possible error conditions:
5693 o The buffer formatting routines now check that the destination
5694 buffer really has enough space to add the data. This applies for
5695 both buffer formatting and unformatting
5696 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5697 unformatting was changed to accomodate following rules:
5698 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5699 sent to the function while XXX_*STRING will not allocate or copy
5700 the data into the buffer. Instead it sets the pointer from the
5701 buffer into the pointer sent as argument (XXX_*STRING used to
5702 require that the pointer must be allocated already). This change
5703 makes this whole thing a bit more consistent and more optimized
5704 (note that the data returned in the unformatting with XXX_*STRING
5705 must not be freed now). The routines return now -1 on error.
5707 o Tried to find all code that use buffer_format and buffer_unformat
5708 and added return value checking to prevent formatting and
5709 especially unformatting errors and possible subsequent fatal
5712 o Changed ske->x and ske->KEY to mallocated pointers in
5713 lib/silcske/silcske.h. Fixed possible data and memory leak.
5715 o Added return value checking to all *_parse* functions. Fixed
5716 many memory leaks as well.
5718 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5719 so that buffer overflows would not happen. All code now also
5720 checks the return value as it can fail.
5722 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5724 * Added reconnection support to server if the normal server looses
5725 its connection to the router (for example if router is rebooted).
5726 The server performs normal reconnection strategy implemented
5727 to the server. Affected file silcd/server.c.
5729 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5731 * Added new packet type SILC_PACKET_SET_MODE that is used to
5732 distribute the information about changed modes (for clients,
5733 channels and clients channel modes) to all routers in the
5734 network. Updated the protocol specification accordingly.
5736 Added functions into silcd/packet_send.c and
5737 silcd/packet_receive.c: silc_server_send_set_mode,
5738 silc_server_set_mode.
5740 Added new files silcmode.[ch] into lib/silccore that implements
5741 the encoding and decoding of Set Mode Payload. Added new type
5742 SilcSetModePayload. Moved the definitions of different modes
5743 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5745 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5747 * Oops, a little mistake in server's connection authentication
5748 protocol. The protocol is not ended with FAILURE but with
5749 SUCCESS if the authentication is Ok. :) Affected file is
5752 * Implemented NICK_CHANGE notify handling in server in the file
5753 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5754 the local clients on the channel. After the changing nickname
5755 in router environment snhould work and the [<unknown>] nickname
5756 should appear no more.
5758 The silc_server_replace_id function that receives the Replace ID
5759 payload now sends the NICK_CHANGE notify type also in the file
5760 silcd/packet_receive.c
5762 * Changed WHOIS and IDENTIFY command to support the maximum amount
5763 of arguments defined in protocol specs (3328 arguments). This
5764 fixed a bug that caused problems when there were more than three
5767 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5769 * Added extra parameter, command identifier, to the
5770 silc_client_send_command so that explicit command identifier
5773 Changed that ID list routines uses specific command identifier
5774 when sending WHOIS/IDENTIFY requests to the server so that they
5775 can be identified when the reply comes back.
5777 Affected files lib/silcclient/command.[ch],
5778 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5780 * Added `sender' argument to silc_server_packet_send_to_channel
5781 to indicaet the sender who originally sent the packet to us
5782 that we are now re-sending. Ignored if NULL. Affected file
5783 silcd/packet_send.[ch].
5785 * Added some server statistics support in silcd/server_internal.h
5786 SilcServerStatistics structure and around the server code. Also
5787 send some nice statistics information when client is connecting
5790 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5792 * Fixed channel ID decoding in server's JOIN command reply in
5793 silcd/command_reply.c
5795 * Fixed braodcasting of replace ID payload to not to send it if
5796 we are standalone server in silcd/packet_receive.c.
5798 * Fixed all channel message sending routines to not to send
5799 packets to clients that has router set, since they are routed
5800 separately in the same function earlier. Affects file
5801 silcd/packet_send.c and all channel packet sending functions.
5803 * In USERS reply, res_argv[i] are not allocated, the table
5804 is allocated. Thus changed that free the table, not its
5807 * In server's whois_check and identify_check if the client is
5808 locally connected do not send any WHOIS commands - they are not
5811 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5813 * Fixed some minor bugs in client when sending WHOIS command. The
5814 arguments was in wrong order.
5816 * Removed statis function add_to_channel from server in
5817 silcd/command.c that was previously used with the joining but
5820 * Tested USERS command in router environment successfully with two
5821 routers, two servers and two clients.
5823 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5825 * Reorganized the USERS command and command reply in client library
5826 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5827 When the command is given by user we register a pending command
5828 callback that will reprocess the command after the reply has been
5829 received from the server. When reprocessing the packet we then
5830 display the information. Thus, the USERS information is displayed
5831 now in the command callback instead of in the command reply
5832 callback. The processing of the command is same as previously
5833 when server has sent the command reply in the JOINing process.
5835 * Added to USERS command in silcd/command_reply.c to join the client,
5836 we didn't use to know about, to the channel after we've created
5837 a client entry for it. Also, for clienet we did know already still
5838 check whether it is on the channel or not and add it if not.
5840 * Removed silc_server_command_join_notify as the function and its
5843 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5845 * Changed the client's pending command handling to the same as the
5846 server's pending command handling. It is also now possible to
5847 execute command reply functions from other command reply
5848 function as the function callbacks for commands and command
5849 replies are one and same. The pending commands are not static
5850 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5851 in client connection context. Thus, pending commands are server
5852 connection specific as it is convenient.
5854 Changed the function silc_client_command_pending and
5855 silc_client_command_pending_del and added new function
5856 silc_client_command_pending_check. Removed the
5857 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5860 * Added cmd_ident, current command identifier, to the client
5861 connection context in lib/silcclient/client.h to keep track on
5862 command identifiers used in command sending. Client's command reply
5863 function handling now supports the mandatory command identifiers.
5865 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5866 funtions in client to fully support pending command callbacks.
5868 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5869 as one of the arguments to the application in the command reply
5872 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5873 before first releasing SILC but came back. Now it is removed again
5874 and should come back nomore. The FORWARDED flag was used only
5875 by the JOINing procedure by forwarding the command packet to router.
5876 Now, the JOINing procedure has been changed to more generic (due
5877 to various router environment issues) and FORWARDED is not needed
5878 anymore for anything. The protocol specification is yet to be
5881 Now, removed silc_server_packet_forward from server and the flag
5882 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5884 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5886 * Renamed NAMES command to USERS command. The NAMES was named that
5887 due to historical reasons. Now it is renamed. Also, rewrote
5888 parts of the USERS command. The nickname list is not sent anymore
5889 by the server. Only Client ID and mode lists are sent in the USERS
5890 command. Changed this also to the protocol specification.
5892 The client now resolves the names and stuff after it receives
5893 the USERS list from the server when joining to the channel.
5895 * WHOIS and IDENTIFY commands has been changed to support multiple
5896 Client ID's per command. One can now search for multiple users
5897 in the network by sending only one WHOIS or IDENTIFY command.
5898 Changed the code and the protocol specifications.
5900 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5901 uses silc_server_command_whois_parse to parse the request. */
5903 * If normal server, do not parse the WHOIS and IDENTIFY requests
5904 before sending it to the router. Saves some time.
5906 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5908 * Fixed JOIN command on client library. Wrong number of arguments
5909 used to crash the client.
5911 * Added silc_server_channel_has_global function to check whether
5912 channel has global users or not.
5914 * Added silc_server_channel_has_local function to check whether channel
5915 has locally connected clients on the channel.
5917 * The silc_server_remove_from_one_channel now checks whether the
5918 channel has global users or not after given client was removed from
5919 the channel. It also checks whether the channel has local clients
5920 on the channel anymore. If it does not have then the channel entry
5921 is removed as it is not needed anymore.
5923 * The silc_server_notify now checks on JOIN notify whether the joining
5924 client is one of locally connected or global. If it is global then
5925 the channel has now global users on the channel and that is marked
5926 to the channel entry. Also, it now saves the global client to
5927 global list who is joining and JOINs it to the channel. This is
5928 for normal server, that is.
5930 Changed silc_server_send_notify_on_channel,
5931 silc_server_packet_relay_to_channel and
5932 silc_server_packet_send_to_channel check if we are normal server
5933 and client has router set (ie. global client) do not send the
5934 message to that client, as it is already routed to our router.
5936 * Implemented LEAVE notify type handling in silc_server_notify
5939 * Tested LEAVE command in router environment successfully. Tested
5940 with two routers, two servers and two clients.
5944 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5946 * Implemented SIGNOFF notify type handling in silc_server_notify
5949 * silc_server_remove_id now removes the client entry from all channels
5950 it has joined and thusly sends SIGNOFF notify type.
5952 * Rewrote the NAMES list generation in server by removing two excess
5953 loops. The lists are created now inside one loop.
5955 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5957 * silc_server_remove_channel_user checks now also global list
5958 for channel and client.
5960 * silc_server_new_channel_user checks now both local and global
5961 list for channel and client. Fixed a bug in client id decoding.
5962 Used to decode wrong buffer.
5964 * silc_server_channel_message checks now both local and global
5965 list for channel entry.
5967 * Tested channel joining (hence JOIN) in router environment
5968 successfully. Tested with two routers, two servers and two
5971 * Tested channel message sending in router environment successfully.
5973 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5975 * Added silc_server_save_channel_key into server.[ch] to save the
5976 received channel key in Channel Key payload processing. It is
5977 also used in JOIN command reply handling.
5979 Equivalent function silc_client_save_channel_key added into
5980 client.[ch] into client library.
5982 * Changed JOIN command reply to send information whether the channel
5983 was created or not (is existing already) and the channel key
5984 payload. Changed protocol specs accordingly.
5986 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5987 the request was sent by ID and not by nickname. Crashed on
5990 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5992 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5993 now correctly save the received data.
5995 * silc_server_free_sock_user_data now notifies routers in the
5996 network about entities leaving the network.
5998 At the same time implemented functions silc_server_remove_id
5999 and silc_server_send_remove_id to receive and send REMOVE_ID
6000 packets. The packet is used to notify routers in the network
6001 about leaving entities. The ID removed will become invalid in
6004 * Added function silc_idlist_del_server into server. Removes and
6005 free's server entry from ID list.
6007 * silc_server_private_message function now checks, if we are router,
6008 that the destination ID really is valid ID, naturally.
6010 * In router when NEW_ID packet is received (for new client) the
6011 hash of the Client ID is saved in the ID Cache but the
6012 client->nickname is set to NULL, instead of putting the hash
6015 IDENTIFY command now also checks that client->nickname must be
6016 valid. If it is not if will request the data from the server who
6017 owns the client. Added new function
6018 silc_server_command_identify_check.
6020 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6021 to set the command to already allocated Command Payload.
6023 * Tested private message sending in router environment with two
6024 routers, two servers and two clients. Fixed minor bugs and now
6027 * Fixed segfault from client's NAMES command. Used to crash if
6030 * Forwarded packets must not be routed even if it is not destined
6031 to the receiver. Changed server code comply with this.
6033 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6035 * Added `require_reverse_mapping' boolean value to ServerParams
6036 structure. If TRUE (not default) the server will require that
6037 the connecting host has fully qualified domain name.
6039 If the reverse mapping is not required and hostname could not be
6040 found the IP address is used as hostname.
6042 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6044 * Implemented version string checking to both client and server.
6045 The check is incomplete currently due to the abnormal version
6046 strings used in development version of SILC.
6048 * Changed all command functions in server to use the new
6051 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6053 * Changed char *data to unsigned char *data in ID Cache system to
6054 support binary data as ID Cache data. Changed code to support
6055 binary data in lib/silccore/idcache.c.
6057 * Renamed silc_server_packet_relay_command_reply to
6058 silc_server_command_reply as it is normal packet receiving
6059 function. Rewrote the function to accept command replys for
6060 servers and not only for clients.
6062 * Mark remote router always as registered server if we are connecting
6063 to it. Otherwise, commands sent by the router to us are ignored.
6065 * All ID List find routines now returns the ID Cache Entry pointer
6066 as well if requested.
6068 * WHOIS command works now in router environment, tested with two
6069 routers, two servers and two clients.
6071 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6072 in router environment (as it is almost equivalent to WHOIS) but
6073 hasn't been tested thoroughly. Added new functions:
6075 silc_server_command_identify_parse
6076 silc_server_command_identify_send_reply
6077 silc_server_command_identify_from_client
6078 silc_server_command_identify_from_server
6080 * Disabled route cache adding because adding two different ID's with
6081 same IP replaces the old cache entry thus giving wrong route.
6082 The entry->router->connection is always the fastest route anyway
6083 so route cache may not be needed. Of course, new routes maybe
6084 established after receiving the ID when the entry->router->connection
6085 might not be anymore the most optimal.
6087 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6089 * Add route cache for received ID for fast routing.
6091 * Added silc_server_packet_route to route received packet on router
6092 that is not destined to us.
6094 * Renamed silc_server_get_route to silc_server_route_get.
6096 * Added id_string and id_string_len fields into SilcServer to
6097 include encoded ServerID for fast comparing without excess
6098 encoding of the ID's.
6100 * Cleaned up WHOIS command on server side. Added following static
6103 silc_server_command_whois_parse
6104 silc_server_command_whois_check
6105 silc_server_command_whois_send_reply
6106 silc_server_command_whois_from_client
6107 silc_server_command_whois_from_server
6109 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6110 arguments in command replies. All command functions should be
6111 updated to use this macro.
6113 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6115 * Minor typo fixes on command reply handling on server.
6117 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6119 * Added silc_server_command_add_to_channel internal routine to add
6120 the client to the channel after router has created the channel and
6121 sent command reply to the server.
6123 * Added generic silc_server_send_command to send any command from
6126 * Use static buffer with ID rendering instead of duplicating data.
6128 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6130 * Fixed a channel user mode bug when joining to a channel server gave
6131 everybody channel founder rights, oops.
6133 * We mark ourselves as the router of the incoming server connection
6134 if we are router ourselves. This way we can check in some packet
6135 sending functions whether it is locally connected server. For
6136 incoming router connections we put NULL.
6138 * For router sending packets locally means now always sending the
6139 packet cell wide; to local clients and local servers. For normal
6140 server sending packet locally means sending it to only local
6143 * Fixed the JOIN command to really work in router environment. If the
6144 channel is created it is always created by the router. Router is
6145 also responsible of making the initial joining to the channel,
6146 sending JOIN notify to the sending server and distributing
6147 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6148 does not exist server doesn't do anything else but forward the
6149 command to the router which performs everything.
6151 * Added silc_server_send_channel_key function to send the Channel Key
6154 * Added silc_server_create_channel_key to create new channel key. The
6155 channel key is now re-generated everytime someone joins or leaves
6156 a channel, as protocol dictates. Note: channel->key_len is the
6159 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6161 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6162 packet_receive.[ch] to separate packet sending and receiving
6163 routines. The server.[ch] now includes everything else including
6164 actual packet processing (writing and reading data) and other
6167 Renamed silc_server_private_message_send_internal to
6168 silc_server_send_private_message. The routine is still though
6169 used only to relay private messages as server does not send
6170 private messages itself.
6172 Renamed silc_server_new_channel to silc_server_create_new_channel
6173 and added new function sicl_server_new_channel that handles the
6174 incoming New Channel packet. Added also new sending function
6175 silc_server_send_new_channel to send New Channel Payload.
6177 * Added new function silc_server_notify to process incoming notify
6178 packet to the server/router. Server may then relay the notify
6179 to clients if needed.
6181 * Added new function silc_server_new_channel_user to process incoming
6182 New Channel User packet. Router will redistribute the packet and
6183 send JOIN notify to its local clients and locally connected servers
6184 if needed. Normal server will send JOIN notify to its local client
6185 on same channel when received this packet. Added also corresponding
6186 sending function silc_server_send_new_channel_user to sent the
6189 * Added boolean route argument to send_notif_to_channel and
6190 packet_send_to_channel functions to attempt to route the packet
6191 if it is TRUE and send only locally if it is FALSE.
6193 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6195 * silc_server_replace_id now broadcasts the received replace ID
6196 packet if it is not broadcast packet already. The router must
6197 broadcast to inform other routers about changed ID.
6199 * Added backpointer to server's router into SilcServer context in
6200 silcd/server_internal.h.
6202 * Fixed silc_server_packet_broadcast to send correct broadcast
6205 * The channel key is now distributed to the local client as soon
6206 as it is received from the router (in router environment) so that
6207 no other packet may be sent for the channel until client has
6210 * silc_server_remove_channel_user now broadcasts the received
6211 Remove Channel User packet if it is not broadcast packet already.
6212 The router must broadcast to inform other routers about removed
6215 * Added users field into SilcPacketContext that is a reference count
6216 of the context. One can increase the reference count by calling
6217 silc_packet_context_dup which is now changed to just increase the
6218 reference count instead of duplicating the data. The reference
6219 count is decresed by calling silc_packet_context_free that will
6220 free the data after the reference count hits zero.
6222 For now on the packet context and everything allocated into it
6223 (including the raw packet from network) must be freed by calling
6224 the new silc_packet_context_free function. Added also new function
6225 silc_packet_context_alloc that must be used now to allocate the
6226 context. This also means that if a routine is asynchronous from
6227 silc_[client/server]_packet_parse_type the packet context must
6228 be duplicated by calling silc_packet_context_dup. Otherwise it
6229 gets free'd after silc_[client/server]_packet_parse_type returns.
6230 Also, one must remember that if packet is duplicated then its
6231 reference count must be decresed by calling the free function as
6232 many times as it was duplicated.
6234 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6235 from both client and server.
6237 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6239 * Made joining to a channel working in router environment.
6241 * Cleaned up JOIN command on server side and create function
6242 silc_server_command_join_channel internal routine to make the
6245 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6247 * Changed silc_command_pending list to SilcDList. Also, added
6248 `ident' field to SilcServerCommandPending structure to identify
6249 the reply and to call correct callback.
6251 Added silc_server_command_pending_check function to replace the
6252 corresnponding macro. The silc_command_pending list is not
6255 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6256 to set identifier to previously allocated Command Payload. It
6257 is used to set identifier for command when resending Command
6260 * Added silc_command_payload_encode_payload to encode Command
6261 Payload buffer from SilcCommandPayload structure.
6263 * Added silc_argument_payload_encode_payload to encode Argument
6264 payload buffer from SilcArgumentPayload structure.
6266 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6268 * Changed WHOIS command to support router connection on server side.
6269 The whois request is always sent to router unless the server is
6270 standalone server. After server has received the reply from the
6271 router will it send the reply to the client.
6273 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6274 broadcast received broadcast packet. The function is used only
6275 by router. The broadcast packet is always sent to the router's
6278 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6279 render given ID to printable string, for log files for example.
6281 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6283 * Made basic router to router connections working. At least they
6284 can now connect to each other but nothing really works the way
6285 they are supposed - yet.
6287 * Added new initiator token to RouterConnection configuration
6288 file in silcd/serverconfig.[ch]. It is used to tell whether we
6289 are the initiator to the remote router or whether we'll expect
6290 the other end to connect.
6292 * Moved registering of listener task to silc_server_init, hence
6293 the server starts listenning as soon as it is run, even if it
6294 does not have connections to other routers. Let's see how well
6297 * Changed default connection retry timeouts for more suitable in
6300 * Removed cipher and such arguments from silc_idlist_add_client
6301 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6302 Added new function silc_idlist_add_data to add the keys and stuff
6305 * Added SilcIDListData structure and added it to SilcClientEntry
6306 and SilcServerEntry as their first field in the structure. This
6307 way we can explicitly cast the ID entries to the SilcIDListData
6308 structure and get common data for the entries. In past, we had
6309 to first check what type of connection it is and then cast it to
6310 correct ID entry type. Now, we can directly cast the opaque
6311 pointer to the SilcIDListData (no matter what ID entry it actually
6312 is) and get the data needed.
6314 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6316 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6317 in some circumstances even if threre were timeout tasks, though not
6318 IO tasks, but tasks anyway. Now fixed.
6320 * Defined SilcServerConnection structure to hold connection specific
6321 stuff about directly connected servers and routers. The definition
6322 is currently in silcd/server_internal.h. I thought about having
6323 a bit more important role fro this struct but for now it is used
6324 only when connecting to other server (or router actually).
6326 * Added connecting retry support in server when connecting to
6327 router(s). The retry feature implement exponential backoff
6328 algorithm. Also, added SilcServerParams structure to hold default
6329 parameters for server. For now, it include these retry settings
6330 and are hard coded. After server is moded to be as Silc Server
6331 Library this structure will be more important.
6333 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6335 * Changed client librarys channel->clients table to SilcList and
6336 changed code accordingly.
6338 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6340 * Changed client's channel table to SilcList and changed code
6341 accordingly. Also changed SilcChannelClientEntry to include back-
6342 pointer to the channel so that client entry can use that structure
6343 as list as well and we have fast cross-reference to the channel.
6344 This change dramatically decreased the complexity of channel
6345 handling with client entry and vice versa (removed one extra
6346 loop when searching for channel entry from many functions).
6348 * Changed server->sim from table to SilcDList and changed code
6351 * NAMES command can now be used from user interface. It will show
6352 the user list on the channel, neatly.
6354 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6355 Code now saves realname of the user if it becomes available.
6357 * Renamed configure.in to configure.in.pre and made ./prepare
6358 script to automatically add correct version string to
6359 configure.in which it creates from configure.in.pre.
6361 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6363 * NAMES command reply now shows users mode with the nickname when
6366 * Moved silc_client_ch[u]mode[_char] functions from
6367 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6368 place sucks, they are utility functions and should be in some
6371 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6373 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6376 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6380 * Added TRQ (efficient deque and list library) into lib/trq. This is
6381 a very good list library that is currently used in the SILC. Defined
6382 SilcList API over the library because I didn't like the API very
6383 much. See lib/trq/silclist.h for the API and examples of how to
6384 use the API. Fixed various places in the code to use the new
6385 SilcList API. The SilcList is meant for lists that has a structure
6386 already defined as a list. It is not suitable to add just some
6387 context to the list (in TRQ, the context is the list actually).
6389 So, I defined SilcDList that can be used for the purpose where
6390 predefined list structure does not exit. This can be used as
6391 such list. Now some context just can be added to the SilcDList.
6392 Currently this list is not used in the SILC just yet, though there
6393 are a lot places where this can replace dynamically allocated
6394 tables and I will fix these places, later, to use SilcDList.
6395 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6396 and use TRQ internally).
6398 Also fixed some annoying warning messages that the original TRQ
6399 code generated. Also minor changes to TRQ's Makefile.in.
6401 * Added support for querying by Client ID to both WHOIS and
6402 IDENTIFY commands into server, as required by the protocol.
6404 * Removed method function pointers from SilcBuffer structure. They
6405 weren't used to anything and just increased the context size for
6406 no good reason. This change also made silc_buffer_alloc and
6407 silc_buffer_free functions inline functions.
6409 * Disabled command flooding detection support until it's fixed so
6410 that it accepts commands in but does not execute them more than once
6413 * Added silc_net_localhost(), to return local hostname, into
6414 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6415 that must be initialized before calling silc_client_init.
6417 * Added new function: silc_server_send_notify_on_channels to send
6418 notify messages to all channels client has joined. It is assured
6419 that the message is sent only once per client.
6421 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6422 lib/silcutil/silcutil.[ch] as silc_format function. The new
6423 function is generic and is used by server as well, not only by
6424 the logging routines.
6426 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6427 the provided version string was not acceptable. Added new function:
6428 silc_ske_check_version into lib/silcske/silcske.h. The function
6429 must be implemented by the application (client or server) and it
6430 does not reside in the SKE library. The function checks the version
6431 string remote end sent.
6433 * Added back pointers (to opaque context and to SilcSocketConnection)
6434 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6436 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6437 duplicate packet context structure.
6439 * Changed `notify' client operation to send same arguments as client
6440 receives from server except for ID's. ID's are mapped to correct
6441 ID entry and that is returned. Also, if channel entry is not sent
6442 by server but the notify is for channel the channel entry is sent
6443 to application (otherwise application doesn't know that it is for
6444 channel (library gets it from packet's Destination ID)).
6446 * Added silc_client_remove_from_channels into client library to
6447 remove a client from all channels it has joined to. Used when
6448 received SIGNOFF notify from server. Added also new function
6449 silc_client_replace_from_channels to replace old ID entry with
6450 new ID entry on all channels. Used when received NICK_CHANGE
6453 * Fixed ID Cache list handling in silc_idlist_get_client in
6454 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6455 to get (or query) client by ID.
6457 * Updated TODO list.
6459 * Added connection authentication status message defined by the
6460 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6461 support for these into the code in client and server side.
6463 * Added generic function silc_client_send_command to send any command
6464 with variable argument list. Application should use this function
6465 to send commands if the command functions provided by the library
6466 does not suite for the application's user interface needs.
6468 * Added new `failure' client operation. Application is notified about
6469 received failure packet if client is executing a protocol. In this
6470 case the protocol's execution has failed.
6472 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6473 is required by the protocol.
6475 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6476 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6479 * Added status flag to SilcSKE object to indicate realtime status
6480 of the SKE protocol.
6482 * Application receives now exactly same command reply arguments as
6483 the library receives from server. However, if ID is received the
6484 corresponding ID entry is returned to the application (eg. Client
6485 ID is mapped to correct SilcClientEntry entry and that is returned).
6486 Changed command_reply client operation due to this change.
6488 * Changed all ID's in commands and in command replys as ID Payloads.
6489 Change affected both client and server side codes.
6491 All ID's sent in SILC network (with execption of ID's in SILC
6492 Packet header) are sent in ID Payload to support variable length
6495 * Server now notifies nick changes and notifies all clients on
6496 the channels about the new nickname (about the new Client ID,
6499 * Implemented CMODE command to change channel modes. Supports all
6500 channel modes defined by the protocol specs except ban and invite
6501 lists. (Also, private channel key mode is supported but support for
6502 setting private channel key in client is missing, thus, this mode
6503 has no effect on client side (except that server requires that the
6504 client uses private channel key and normal channel traffic does not
6507 Also, invite mode works per se, but INVITE command does not work
6508 yet correctly, so you can set channel as invite only channel but
6509 inviting clients to the channel does not work (it is yet to be
6510 thought what's the best way to do it).
6512 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6513 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6514 Implemented CUMODE command to change user's mode on the channel.
6515 Supports all modes defined by the protocol specs.
6517 * Added NAMES command reply to return users modes on the channel.
6519 * Removed unnecessary and slow ciphers from lib/silccrypt.
6521 * Set SO_KEEPALIVE option to connection sockets by default.
6523 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6525 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6526 redefined the Notify Payload into protocol specs.
6528 * Added silc_id_payload_parse_id to get ID directly from raw
6531 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6533 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6534 accept searching by Client ID as well.
6536 * Added support for LEAVE and SIGNOFF notify types in client library.
6538 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6539 to parse ID Payload from raw data.
6541 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6543 * Added flags parameter into silc_ske_assemble_security_properties
6544 function in lib/silcske/silcske.[ch].
6546 * Changed notify client operation to fit better for notify messages
6547 sent by server. The notify payload received from server is now
6548 passed to the application (after parsing it to SilcNotifyPayload).
6549 It is application's responsibility to retrieve the arguments
6550 from the payload and show the message the way it wants. The message
6551 sent by server is implementation specific.
6553 * Changed public keys to comply with the protocol specification.
6554 Old public keys are not supported anymore and are not compatible.
6556 * Removed nickname from Channel Payload as the latest draft removed
6557 it. The client must resolve the nickname from the NAMES command
6558 reply received when it joined the channel.
6560 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6562 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6564 * Fixed some errors in protocol specification drafts.
6566 * Created lib/silccore/silcnotify.c to implement Notify Payload
6567 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6568 generic payloads described by protocol specifications. The file
6569 includes implementations for ID Payload and Argument Payload.
6571 * Changed Command Payload implementation to use the new Argument
6572 Payload. Changed command_xxxx_payload to command_payload_xxxx
6573 to comply with SILC coding conventions.
6575 * Added suppport for Argument Payload handling in Notify Payload
6576 implementation as protocol requires it. Added the new support
6577 into server and client lib as well.
6579 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6581 * Added support for multiple nicknames on same channel. [n] is
6582 added locally to the nickname if there are more than one same
6583 nicknames on the channel.
6585 * Server now sends all nicknames that matched WHOIS request.
6586 Client also shows the list received from server.
6588 * Added TOPIC command to client side. User can now set and show
6589 current topic on channel.
6591 * Added MOTD command to client and server. Also, server sends the
6592 motd when client connects to the server.
6594 * Changed version strings to comply ISO 8601.
6596 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6598 * Fixed protocol error handling in client library. It should now
6599 cope even if the SKE fails for some reason.
6601 * Made new protocol specification drafts for submitting to IETF.
6603 * Implemented TOPIC command to server in silcd/command.c.
6605 * Added two new notify types into lib/silccore/silcnotify.h:
6606 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6607 notify nickname change and topic setting/change on a channel.
6609 * API change of command_reply operation in client library. The
6610 application gets now the status type received from server as well.
6612 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6614 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6616 * Cras fixed and optimized the packet handling even further and
6617 it should work now. Minor change to the prototype of function
6618 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6620 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6622 * Added new function into lib/silcutil/silcschedule.[ch]:
6623 silc_schedule_with_fd to select() a specified fd. The function
6624 returns after timeout expires or data arrives or goes. The
6625 function is used by packet routines to wait that all data is
6626 received from network.
6628 * Fixed data reading from network in lib/silccore/silcpacket.c.
6629 The code now assures that all data is read from the fd and then
6630 continues packet processing. This was a bug fix since the code
6631 used to drop some data in some circumstances.
6633 * Added new function into lib/silcclient/client.[ch]:
6634 silc_client_start_key_exchange to start key exchange after
6635 connection has been established to server. The code internally
6636 now uses this funtion but its main purpose was to provide it
6637 for applications that perform their own connecting. After
6638 application has created a connection it merely calls this
6639 function to start the key exchange between client and server.
6640 The library takes care of everything else after that.
6642 Updated also lib/silcclient/README to explain the usage of
6645 * Do not send to application information that connection has
6646 been established. Application gets notified it by connect
6649 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6651 * Applied cras's patch to add silc_schedule_one function. The
6652 function runs scheduler once and returns.
6654 * Fixed the scheduler after cras messed it up. The timeout
6655 handling works now as it's supposed to work.
6657 * Added into lib/silccore/ silcnotify.h to include notify
6658 message types support. Changed silc_server_send_notify*
6659 functions, in server.[ch], to support those new notify types.
6660 Added the support for the notify types into client library,
6661 as well. Added new notify client operation into ops.h in
6664 * Changed silc_server_packet_send_to_channel to send normal
6665 packets instead of just channel message packets. The function
6666 is now used to send the notify packets to channels. It is not
6667 used to send channel message packets anymore, as server never
6670 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6671 va_arg()s as it seems to require it nowadays. I guess, if SILC
6672 is compiled with older va_arg() the new code should work anyway.
6674 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6676 * Splitted core library. Core library (lib/silccore) includes
6677 now only SILC protocol specific core (and common) components.
6678 Created new utility library (lib/silcutil) that includes more
6679 generic purpose stuff. The stuff for util library was taken
6680 from the old core library. This was minor and easy split.
6682 * Created SILC Client Library (lib/silcclient) that includes
6683 implementation of the SILC client without user interface. This
6684 was major move from silc/ directory. The code has been changed
6685 so that it is transparent towards the user interface. The
6686 silc/ directory includes now the same user interface as before
6687 and it uses the new client library. Read lib/silcclient/README.
6688 Basicly, the client library performs everything else related
6689 to SILC except user interface handling. Also, configuration
6690 files are considered to be part of user interface and library
6691 does not handle them.
6693 This change also changed a lot of structures, function naming etc.
6694 Most important change was that SilcClientWindow object was
6695 renamed to SilcClientConnection in the client library. Created
6696 also new file lib/silcclient/ops.h. Also added new files
6697 silc/local_command.[ch] and silc/client_ops.[ch].
6699 All these changes were made to make it easier for user interface
6700 designers to create what ever user interface for the SILC client
6703 It is also expected that the server will be moved to lib
6704 directory as well and SILC Server Library will be created;
6705 sometimes in the future.
6707 * Removed Local commands from lib/silccore/silccommand.h as
6708 they are application specific and new client library does not
6709 handle any of those anymore.
6711 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6712 old client implementation in silc/.
6714 * Added support for callback functions in SILC_LOG_* macros.
6715 Application can now set its own callbacks that will be called
6716 instead of using the default functions that will always print
6717 the debug messages to stderr (or stdout). Also, debugging can
6718 now be disabled by setting silc_debug to FALSE and re-enabled by
6719 setting it to TRUE. Note, that logging will still work even
6720 if debugging is disabled.
6722 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6723 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6724 silc_log_reset_debug_callbacks.
6726 * To enable debugging in silc client one must give now -d
6727 option on command line.
6729 * Changed silc_schedule_init to automatically allocate task queues
6730 if they are not allocated before calling it.
6732 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6734 * Added GMP 3.1 into math library.
6736 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6738 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6739 a channel in SILC network. The packet is used by servers and
6740 routers to notify other routers that user has left a channel.
6741 This little feature was missing until now. Added the feature
6742 to protocol specification as well.
6744 Added functions: silc_server_send_remove_channel_user and
6745 silc_server_remove_channel_user into server.[ch].
6747 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6748 lib/silccore/silcpacket.h. However, they are not implemented
6751 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6753 * Fixed joining to a channel and sending channel messages
6754 between server and router. The channel message sending should
6755 now work inside a cell.
6757 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6759 * Fixed the private message sending between server and router.
6760 The private message sending should now work inside a cell.
6762 * Added silc_server_replace_id into server.[ch] to replace
6763 existing ID in the SILC network.
6765 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6766 and silc_idlist_replace_server_id into idlist.[ch] in server.
6768 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6770 * Fixed the server to server connections. Server can again now
6771 connect to router. Router to router connections probably does
6774 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6776 * Added dynamic protocol registering support. Now protocols can
6777 registered and unregistered on the fly. Patch by cras.
6779 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6781 * Added lib/contrib directory to hold routines that some platforms
6782 don't have but are needed by SILC.
6784 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6785 into lin/contrib to provide getopt() and getopt_long() for
6786 those who don't have it.
6788 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6790 * Added AWAY command to client. When away message is set and
6791 client receives a private message packet the client automatically
6792 replies to the sender with the away message.
6794 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6795 bug seemed to be the cause of recent problems when compiling
6798 * Added version detection support to SKE protocol specification
6799 and added the new changes to the SKE implementation as well.
6800 There were other minor changes in the SKE protocol as well.
6802 Many changes in lib/silcske/silcske.[ch] and in
6803 lib/silcske/payload.[ch].
6805 * Added ^U functionality, clear input line. Patch from cras.
6807 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6809 * Mainly small bugfixes on core library. Fixed some debugging
6810 logging and buffer overflow in silclog.c.
6812 * Updated config.sub and config.guess on the distribution tree.
6814 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6816 * Added command lagging support in server. Client may execute
6817 commands now only once in two seconds.
6819 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6821 * Optimized packet reception. MAC computation and checking is now
6822 also more optimized. A lot previously duplicated code is now
6823 used as generic by both client and server.
6825 * Fixed key pair generation in clientutil.c
6827 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6829 * Added into lib/silccore/silcbufutil.[ch] new function;
6830 silc_buffer_realloc.
6832 * Moved generic packet sending/encryption functions to
6833 lib/silccore/silcpacket.[ch] from client and server. Some
6834 rewriting of the functions.
6836 * Moved all generic packet reception/decryption functions to
6837 lib/silccore/silcpacket.[ch] from client and server. The
6838 packet processing is now much cleaner in both client and server.
6839 These were major changes in both client and server.
6841 * Created many common functions in server to do packet sending.
6842 Previously code were duplicated a lot, this has been removed
6845 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6847 * Rewrote major parts of the ID cache system. Don't know
6848 whether it is better now or not but at least the API is more
6851 * Major rewrite on ID cache stuff on client because of the ID
6852 cache API changes. Added idlist.c to client.
6854 * Also major rewrite on ID cache stuff on server as well.
6855 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6856 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6857 in hand, instead they are all put into the ID cache system now.
6858 All server_idlist_* routines uses ID cache now instead of
6859 traversing its own lists (those lists does not exist anymore).
6860 SilcIDList though still exists. Also, SilcXXXEntry's are
6863 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6865 * Finally made the SKE implementation compliant to the protocol
6866 specification. All mp integers are now binary encoded as
6867 opposed being HEX encoded.
6869 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6872 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6873 functions: silc_[encode/decode]_pem. Also added function
6874 silc_encode_pem_file to PEM encode with newlines ('\n') for
6877 * SILC public keys are now encoded either PEM or binary. Same
6878 option is for private keys as well. By default private keys
6879 are binary encoded and public keys PEM encoded. Silly HEX
6880 encoding were removed.
6882 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6883 function to create fingerprints.
6885 * Fixed a bug in SHA1; does not change the original data anymore.
6887 * Partly implemented INFO command on client and server side.
6888 Fixed CLEAR command. Changes to SERVER command; show current
6889 server(s) when giving command without arguments. Added
6890 VERSION command to client.
6892 * Added check to server that unregistered connections cannot
6893 execute commands (unless it is specificly allowed).
6895 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6897 * Fixed screen refresh.
6899 * Fixed channel joining bug from client. On some circumstances
6900 client tried to join to a channel it had already joined.
6902 * Added public key verification process into client's protocol.c.
6903 The client now verifies the public key from user and saves
6904 it into ~./silc/serverkeys/ directory.
6906 Added into: clientutil.[ch]: silc_client_verify_server_key.
6908 * Changed SKE protocol's silc_ske_initiator_finish function
6909 to accept callback function that verifies the received public
6910 key. Removed old silc_ske_verify_public_key function.
6912 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6914 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6915 silc_pkcs_private_key[_data]_set.
6917 * Made the password and public authentication more cleaner in
6918 server's protocol.c.
6920 * Removed historic and obsolete protocol `channel_auth' from
6921 both client and server.
6923 * Removed wrong way of sending command status messages from
6924 server to client in server's command.c. The old way violated
6925 protocol specification.
6927 Changes to silccore/silccommand.[ch]: removed
6928 silc_command_encode_status_payload -> not needed anymore,
6929 changed silc_command_encode_payload_va to accept extra
6930 argument on variable argument list. The argument type must
6931 now be provided to the function. Also, added new function:
6932 silc_command_encode_reply_payload_va which is same as
6933 normal command_encode_payload_va except command status type
6934 is provided as extra argument.
6936 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6938 * Added ~./silc directory handling. The directory includes the
6939 public and private keys for the client.
6941 Added silc_client_check_silc_dir, silc_client_create_identifier
6942 and silc_client_load_keys.
6944 * Implemented SILC protocol compliant public key. Added public
6945 and private key saving to and loading from files.
6947 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6948 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6949 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6950 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6951 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6953 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6954 silc_pkcs_load_[public/private]_key.
6956 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6958 * Added silc_server_get_route (route.[ch]) to get connection
6959 data for the fastest route for given ID.
6961 * Implemented INVITE command on client and server. The command
6962 were re-defined in the SILC Protocol Specification and the
6963 implementation now complies with the specification.
6965 * Implemented PING command on client and server.
6967 * Implemented NAMES command on client and server. The server side
6968 supports currently only normal server not router server yet.
6969 Some changes to NAMES definition in SILC protocol specification.
6971 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6973 * Implemented LEAVE command on client and server.
6975 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6976 again. This change was made to the protocol as well. Server
6977 should not violate the protocol specification anymore.
6979 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6981 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6982 was tested. SOCKS4 was not but should work anyway.
