5 Sat Feb 9 14:54:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
7 * Allow zero length channel messages inside the Channel Message
8 Payload. Affected file lib/silccore/silcchannel.c.
10 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
13 * Removed lib/silcclient/README and created HTML file
14 lib/silcclient/silcclient_using.html, which is now included
15 as part of Toolkit documentation.
17 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
19 * Fixed CUMODE_CHANGE notify handling to change the mode of
20 correct client. Affected file lib/silcclient/client_notify.c.
22 * Make silc_rng_alloc fail if it cannot allocate the sha1
23 hash algorithm. Affected file lib/silccrypt/silcrng.c.
25 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
27 * Fixed the file transfer's key agreement payload to include
28 zero port also if the hostname is NULL because it could not
31 Call file transfer monitor callback now also if error occurs
32 during key agreement protocol.
34 Changed the silc_client_file_send interface to return the
35 SilcClientFileError instead of session id. The session ID
36 is returned into pointer provided as argument.
38 Check that the file exists locally before sending the
39 file transfer request at all.
41 Affected file lib/silcclient/client_ftp.c, silcapi.h.
43 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
44 error than can occur while key agreement protocol. Affected
45 file lib/silcclient/silcapi.h.

48 is changed and +k mode is set in the channel. Affected file
49 irssi/src/silc/core/silc-channels.c.
51 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
52 SILC_LOG_WARNING to give out Warning and not Error. Affected
53 file lib/silcutil/silclog.c.
55 * Fixed the channel message payload decryption in the function
56 silc_channel_message_payload_decrypt to not modify the original
57 buffer before it is verified that the message decrypted
58 correctly. Otherwise, next time it is called with correct
59 channel key it won't encrypt since the payload is corrupted.
60 Affected file lib/silccore/silcchannel.c.
62 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
64 * Do not constantly resize the window. A fix patch by cras.
65 Affected file irssi/src/fe-text/screen.c.

69 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
70 Affected file lib/silcutil/silcnet.c.
72 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
74 * Fixed a bug in hash table internal routine for traversing
75 the table with foreach callback. The current entry may
76 become invalid in the callback but it was referenced after
77 the callback returned.
79 Do not allow auto rehashing of hash table during the
80 silc_hash_table_foreach operation, for same reasons as it is
81 not allowed for SilcHashTableList. Affected files are
82 lib/silcutil/silchashtable.[ch].
84 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
86 * Defined DLLAPI into silcincludes.h and silcwin32.h for
87 Win32 DLL. extern's in header files are now declared with
90 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
92 * Fixed private message handling. It used some old code that
93 caused the client to crash. Affecte file is
94 lib/silcclient/client_prvmsg.c.
96 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
98 * Added function silc_client_add_channel,
99 silc_client_replace_channel_id, and removed functions
100 silc_client_new_channel_id and silc_idlist_get_channel_by_id
103 * Added cross reference of the joined channels to the
104 SilcClientEntry, and changed the SilcChannelEntry's
105 users list to SilcHashTable. The affected files are
106 lib/silcclient/idlist.[ch].
108 * Fixed a bug in hash table tarversing. While the hash table
109 is traversed with SilcHashTableList the table must not be
110 rehashed. It is now guaranteed that auto rehashable tables
111 are not rehashed while tarversing the list. Also defined that
112 silc_hash_table_rehash must not be called while tarversing
113 the table. Added function silc_hash_table_list_reset that must
114 be called after the tarversing is over. The affected files are
115 lib/silcutil/silchashtable.[ch].
117 * Changed all hash table traversing to call the new
118 silc_hash_table_list_reset in server and in client library.
120 * Added function silc_client_on_channel to return the
121 SilcChannelUser entry if the specified client entry is joined
122 on the specified channel. This is exported to application as
123 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
125 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
127 * Fixed founder regaining problem with JOIN command on normal
128 server. The notify for mode change must be sent always and
129 not only if !cmd->pending. Affected file silcd/command.c.
131 * Fixed the WHOWAS command's reply sending to support the
132 lists correctly. Affected file silcd/command.c.
134 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
136 * When sending JOIN command to router for processing the
137 sender's old command identifier was not saved back to the
138 sender's command context, fixed now. The affected file is
141 * Create the key in JOIN command of the router did not return
142 the channel key, added check for this. Affected file is
145 * Fixed a channel ID update bug in JOIN command reply. Do
146 not directly upgrade the ID but call the function
147 silc_idlist_replace_channel_id if the ID was changed.
148 Affected file silcd/command_reply.c.
150 * Fixed memory leaks from command calling if it would fail.
151 Affected file silcd/command.c.
153 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
155 * Applied patches from cras:
157 Memory leak fixes around libaries, irssi window resize fix,
158 new silclist.h and silcdlist.h, all extern inline changed to
161 * Removed dotconf from lib/dotconf, not needed anymore.
163 * Removed TRQ from lib/trq, not needed anymore.
165 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
166 with server connections. Later this will be configurable
167 in config file after new config file is done. Affected file
170 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
172 * Fixed a crash in server related to channel announcements.
173 Affected file silcd/server.c.
175 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
177 * Fixed memory leaks in silc_server_create_new_channel*
178 functions. Affected file silcd/server.c.
180 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
181 which ID was changed. This way the router will send the
182 user list for the channel again, and server won't be in
183 desync in some rare circumstances. Affected file is
184 silcd/packet_receive.c.
186 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
188 * Check for NULL socket pointer in the function
189 silc_server_packet_send_to_channel_real. Affected file
192 * Fixed the BAN notify handling to correctly remove ban
193 list. Affected file silcd/packet_receive.c.
195 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
197 * Fixed some header addition to Toolkit distribution in
198 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
200 * Added lib/silcclient/client_ops_example.h as an template
201 file for application programmers to quickly start using
202 the SilcClientOperation functions in their application.
203 Updated the lib/silcclient/README as well to tell about this
204 nice file made available.
206 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
208 * Call silc_server_remove_from_channels when removing client
209 entry when NO_SUCH_CLIENT_ID was received. Affected file
210 is silcd/command_reply.c.
212 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
214 * Added server & router operator statistics updating. Affected
215 file silcd/packet_receive.c and silcd/command.c.
217 * Fixed the SERVER_SIGNOFF notify handling on normal server
218 not to save the history information for clients. Same was
219 fixed earlier in remove_clients_by_server function, but not
220 here. Affected file silcd/packet_receive.c.
222 * Raised the default connection-retry count from 4 to 7 in
223 server. Affected file silcd/server.h.
225 * Cancel any possible reconnect timeouts when we start the
226 key exchange. Affected file silcd/server.c.
228 * Do not reconnect on connection failure when SCONNECT was
229 given. Affected files silcd/server.[ch].
231 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
233 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
235 * Fixed the NICK command to always give the unformatted
236 nickname to the one giving the NICK command. If unformatted
237 nickname is cached already it will be formatted and the
238 local entry will always get the unformatted nickname.
239 Affected file lib/silcclient/idlist.c.
241 * Fixed some double frees from client library commands.
242 Affected file is lib/silcclient/command.c.
244 * Fixed CUMODE command in server to assure that no one can
245 change founder's mode than the founder itself, there was a
246 little bug. Affected file silcd/command.c.
248 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
250 * Removed the SilcClientCommandDestructor from the client
251 libary, it is not needed anymore. Affected files are
252 lib/silcclient/silcapi.h, command[_reply].[ch],
253 client_notify, idlist.c.
255 * Fixed GETKEY command to first resolve client, and then
256 resolve the server only if the client was not found, instead
257 of resolving both at the same time. Affected file is
258 lib/silcclient/command.c.
260 * Added silc_client_start_key_exchange_cb and lookup the
261 remote hostname and IP address before starting the key
262 exchange with server. The affected file is
263 lib/silcclient/client.c.
265 * The server's public key is now saved using the IP address
266 of the server and not the servername for the filename.
267 The hostname public key filename is checked as an fall back
268 method if the IP address based filename is not found.
270 Fixed the GETKEY command to save the fetched server key
273 Print the remote server's hostname now when new key is
274 received during connection process. Affected file is
275 irssi/src/silc/core/client_ops.c.
277 * Return always our own public key to the client if it asks
278 for it with GETKEY command. Affected file silcd/command.c.
280 * Removed the use_auto_addr variable from default config
281 file since it was in wrong section. Affected file is
284 * Fixed TOPIC_CHANGE notification to not route it when it
285 was sent using silc_server_send_notify_to_channel function.
286 Affected file silcd/command.c.
288 * Fixed silc_server_send_notify_kicked to send the kicker's
289 Client ID also, it was missing. Affected files are
290 silcd/command.c, silcd/packet_send.[ch].
292 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
294 * Do not save client history information in SERVER_SIGNOFF.
295 Fixes the bug in normal server that it does not detect
296 the client becoming valid after the server becomes back
297 online. Affected file silcd/server_util.c.
299 * Added `sock_error' field into the SilcSocketConnection
300 context. When error occurs during socket operation (read
301 or write) the error is saved. Added also new function
302 silc_socket_get_error to return human readable socket error
303 message. Affected files are lib/silcutil/silcsockconn.[ch],
304 lib/silcutil/unix/silcunixsockconn.c, and
305 lib/silcutil/win32/silcwin32sockconn.c.
307 * The server now prints the socket error message in the
308 signoff for client. Affected file silcd/server.c.
310 * Fixed the `created' channel information sending from router
311 to server in JOIN command. Checks now whether the channel
312 really was created or not and set it according that.
314 Fixed the JOIN command to use the client entry's current
315 ID during the joining procedure instead of the one it sent
316 in the command (it is checked though), since it can change
317 between the packet processing and command processing, and
318 would just case unnecessary pain in the client end. Affected
319 file silcd/command.c.
321 * Fixed a channel key payload sending to use correct channel
322 ID when the server was forced to change the channel's ID by
323 router. Router sent the key payload with the old Channel ID.
324 Affected file silcd/packet_receive.c.
326 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
328 * Call silc_server_save_channel_key only if the key payload
329 was provided in the JOIN command's command reply. Affected
330 file silcd/command_reply.c.
332 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
334 * Fixed silc_mp_sizeinbase to return the value correctly with
335 MPI. Affected file lib/silcmath/mp_mpi.c.
337 * Fixed the stop_server signal to correctly stop the scheduler
338 and gracefully stop the server when SIGTERM or SIGINT signals
339 are received. Affected file silcd/silcd.c.
341 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
343 * Simple handling of TERM and HUP signals. Also added some log
344 flushing call around. Affected file is
347 * Fixed small bugs in silclog.c. Now buffering output will take
348 effect after 10 seconds since startup: This will ensure that
349 no important startup messages are lost. Also output redirection
350 will preserve original format ([Date] [Type] message).
351 Affected file is lib/silcutil/silclog.c.
353 * Added two options to the config file, in the logging section:
354 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
355 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
357 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
359 * Do not print the warning about log files not being initialized
360 more than once to avoid excess logging. Affected file is
361 lib/silcutil/silclog.c.
363 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
364 the SIM copying in make install in Makefile.am.pre.
366 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
368 * Rewritten silclog APIs. Globally interesting changes follows:
369 silc_log_set_files() changed to silc_log_set_file().
370 silc_log_set_callbacks() changed to silc_log_set_callback().
371 ROBOdoc documented silclog header file.
372 SilcLogCb now returns bool to wether inihibit the default
373 handler or not (to keep the old behaviour return always TRUE).
374 The new APIs should also fix the problem of the
375 silcd_error.log file that was written in the current directory.
378 Log files streams will remain opened after silc_log_set_file()
379 call, means less CPU usage notably on high traffic servers.
380 File streams are now full buffered, and flushed to the disk
381 every 5 minutes, lesses HD activity and CPU usage.
382 Messages can be redirected, allowing admins to configure
383 one single logfile for all server messages.
384 the silc_log_quick global variable to activate fast-logging.
385 Affected files lib/silcutil/silclog.[ch]
387 * Changed some code to conform new silclog APIs. Affected
388 files are doc/example_silcd.conf.in, silcd/server.c
389 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
392 * Fixed a memory leak that could occur in some situations.
393 Affected file silcd/serverconfig.c.
395 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
397 * Added the silc_client_del_client to remove the client from
398 all channels as well. Affected file lib/silcclient/idlist.c.
400 * Fixed the client library to correctly remove the client
401 from all channels when the client entry is being destroyed.
402 Affected file lib/silcclient/client_notify.c, command.c.
404 * Added auto-nicking support to the client library. If the
405 applicatio now sets client->nickname it will be sent to the
406 server after connecting by the library. This way for example
407 SILCNICK (or IRCNICK) environment variables will have effect
408 and always change the nickname automatically to whatever
409 it is wanted. Affected file lib/silcclient/client.[ch].
411 * Renamed silc_server_command_bad_chars to the
412 silc_server_name_bad_chars and moved it to the
413 silcd/server_util.[ch]. Added also new function
414 silc_server_name_modify_bad to return nickname that
415 includes bad characters as new nickname without those
416 bad characters. This check and modify is now used in
417 silc_server_new_client when the username is initially set
418 as nickname, so it must be checked to be valid nickname.
419 Affected file silcd/packet_receive.c.
421 * The nickname length is now taken from the packet for real
422 and not trusted to strlen() since it clearly can return
423 wrong length for nickname including bad characters. This
424 also applies to channel names. Affected file silcd/command.c.
426 * Removed the lib/silcsilm/modules directory. Modules are now
427 compiled into the lib/silcsim. Fixed the copying of the
428 modules to follow symbolic links in Makefile.am.pre.
430 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
432 * Fixed silc_string_regexify list creation. Fixes bugs with
433 BAN and INVITE commands in server. The affected file is
434 lib/silcutil/unix/silcunixutil.c.
436 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
438 * Removed the command destructor entirely from the server's
439 command and command reply routines. It is not needed, and
440 its usage was buggy and caused crashes. Affected files are
441 silcd/command[_reply].[ch].
443 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
445 * Cancel protocol and NULL sock->protocol if timeout
446 occurred during protocol. Affected file silcd/server.c.
448 * Cancel protocol timeouts always before calling the final
449 callback, to assure that after final callback is called
450 no other state will be called for the protocol anymore.
451 Affected file silcd/protocol.c.
453 * Print error log if incoming connection configuration could
454 not be found. Affected file silcd/server.c.
456 * Fixed JOIN command to correctly save the founder mode
457 to the client on normal SILC server, when the channel
458 was created by the router. Affected file silcd/command.c.
460 * Fixed LIST command (hopefully) to send correct reply
461 packets. Affected file silcd/command.c.
463 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
465 * The silc_packet_receive_process now returns FALSE if the
466 read data was invalid packet, and TRUE if it was ok.
468 The server now checks that if unauthenticated connection
469 sends data and its processing fails the server will close
470 the connection since it could be a malicious flooder.
472 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
474 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
476 * Make sure the warning about error opening a log file is
477 printed only once and not everytime it fails (produces
478 too much useless log). Affected file lib/silcutil/silclog.c.
480 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
482 * Made the silc_server_daemonise() function more readable.
483 Affected file silcd/server.c.
485 * Pid file is now optional, the user may comment it out from
486 the config file. Removed define SILC_SERVER_PID_FILE, we
487 don't need a default any longer. Affected file
488 configure.in.pre, lib/Makefile.am.pre.
490 * Make some use of the pid file. The server now dies at startup
491 if it detects a valid pid file on his path. The server would
492 die anyway in this circumstance, because of the bind() failure.
493 Affected file silcd/silcd.c.
495 * No longer compiling lib/dotconf.
497 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
499 * Fixed JOIN command parsing not to crash. Affected file
500 lib/silcclient/command.c.
502 * Fied the NICK_CHANGE notify to add the new client entry
503 even it is resolved. This removes an <[unknown]> nick
504 thingy bug in the client. Affected file is
505 lib/silcclient/client_notify.c.
507 * Do not try to allocate 0 bytes (efence does not like it)
508 in lib/silccore/silccomand.c when encoding payload.
510 * Do not take IRCNICK as nickname in Irssi SILC client since
511 it is not possible to set nickname before hand connecting
512 the server (TODO has an entry about adding auto-nicking
515 * Changed the silc_server_command_pending to check whether
516 there already exists an pending entry with the specified
517 command, command identifier and pending callback. This is
518 to fix IDENTIFY and WHOIS related crashes that may register
519 multiple pending commands with same identifier. Affected
520 file silcd/command.c.
522 * Fixed the server to reconnect to the router even if it
523 was already reconnecting and EOF was received. This to
524 fix a possibility that the server wouldn't ever try to
525 auto-reconnect to the router. Affected file silcd/server.c.
527 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
529 * Fixed the server's password authentication to use the
530 length of the locally saved password, and not the one
531 sent in the packet. Affected file silcd/protocol.c.
533 * Fixed same password authentication problem in the
534 Authentication Payload handling routines in
535 lib/silccore/silcauth.c.
537 * Yet another password authentication problem fixed with
538 channel password handling in silcd/command.c.
540 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
542 * If first character of string in silc_parse_userfqdn is '@'
543 then do not parse it. Affected file is
544 lib/silcutil/silcutil.c.
546 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
548 * Fixed minor bug in IDENTIFY command reply sending, which
549 caused various weird problems during JOIN when it was
550 resolving names for users. Affected file silcd/command.c.
552 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
554 * Fixed the IDENTIFY command reply sending to chech better valid
555 clients. It was possible to send incomplete list of replies.
556 Affected file silcd/command.c.
558 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
560 * Added silc_client_command[s]_[un]register functions now to
561 dynamically register the commands in client library. Removed
562 the static table of commands. This allows the client library
563 to call commands without causing the application to know about
564 what commands library has called.
566 Removed the INFO command reply kludge to detect when the command
567 was called by library. Now library use its own command reply
568 function for INFO command.
570 Added function silc_client_command_call to call a command.
571 Application can use it to call command, not access the structure
574 Now all commands that are sent by the client library (not
575 explicitly sent by application) use own command reply functions.
577 Affected files around lib/silcclient/ and in
578 irssi/src/silc/core/.
580 * Fixed the WHOIS command reply sending to chech better valid
581 clients. It was possible to send incomplete list of replies.
583 Fixed the WHOIS and IDENTIFY to send the request to router
584 if normal server did not do it and did not find any results.
586 Affected file silcd/command.c.
588 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
590 * Moved the internal data from SilcClient context into its
591 own file, not accesible to application. Affected files
592 lib/silcclient/client.h and lib/silcclient/client_internal.h,
593 and other files in client library.
595 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
597 * Added doc/examples installation target in Makefile.am.pre.
600 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
602 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
603 commands the found client entry will be removed from the
604 cache, after notifying application about the error. Affected
605 file lib/silcclient/command_reply.c.
607 * Changed the /MSG to check for exact nickname user gave, and
608 not let `nick' match `nick@host' if it is only one found. Now,
609 user must type the exact nickname (like nick@host2) even if
610 there are no more than one same nicks found. This is to avoid
611 a possibility of sending nickname to wrong nickname since
612 `nick' could match `nick@host'. Affected file is
613 irssi/src/core/silc-servers.c.
615 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
617 * Do not print "you are now server operator" or similar when
618 giving /away command. Affected files are
619 irssi/src/silc/core/client_ops.c, silc-servers.h.
621 * Made the silc_server_command_pending_error_check to send
622 the same command reply payload it received back to the
623 original sender of the command. This way all arguments
624 that was received by the server will be received by the
625 client too. Affected file silcd/command.c.
627 * Added the silc_idcache_add to return the created cache entry
628 to a pointer. Affected file lib/silccore/silcidcache.[ch].
630 * Add global clients to expire if they are not on any channel.
631 This is because normal server will never know if they signoff
632 if they are not on any channel. The cache expiry will take
633 case of these entries. This is done by normal servers only.
634 The affected files are silcd/command_reply.c,
635 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
637 * If server receives invalid ID notification for WHOIS or
638 IDENTIFY and the ID exists in the lists, it is removed.
639 Affected file silcd/command_reply.c.
641 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
642 in client then client entry that it matches is searched and
643 the nickname is printed on the screen for user. Affected
644 file irssi/src/silc/core/client_ops.c.
646 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
648 * Use cache entry expire time in the LIST command reply to
649 purge old entries from the cache after the LIST command
650 reply has been received. This way we don't have non-existent
651 entries in the cache for too long. Affected file is
652 silcd/command_reply.c.
654 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
656 * If we are normal server, and we've not resolved client info
657 in WHOIS or IDENTIFY from router, and it is global client,
658 we'll check whether it is on some channel. If it is not
659 then we cannot be sure about its validity and will resolve it
660 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
661 file silcd/command.c.
663 * Search channel by name (if possible) rather than by ID
664 in IDENTIFY command's command reply. Affected file is
665 silcd/command_reply.c.
667 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
669 * Distribute to the channel passphrase in CMODE_CHANGE notify.
670 Updated specs and implemented it. Affected file silcd/command.c,
671 silcd/packet_send.c and silcd/packet_receive.c.
673 * Implemented the <founder auth> payload handling in the JOIN
674 command. If provided all conditions for channel joining
675 except requirement to provide correct passphrase can be
676 overrided by the channel founder. Updated the protocol specs.
677 Affected file silcd/command.c.
679 Added support for founder auth in JOIN command in client
680 library. Fixed the parsing of the JOIN command now to support
681 all options as they should be. The affected file is
682 lib/silcclient/command.c.
684 * Optimized the WHOIS and IDENTIFY commands to send the request
685 to router only if it includes nicknames or other names. If
686 they include only IDs then check the local cache first before
687 routing. Affected file is silcd/command.c.
689 * Added channels topic announcements. Affected file is
690 silcd/packet_receive.c and silcd/server.c.
692 * Fixed the silc_server_send_notify_topic_set to really destine
693 the packet to channel. Affected file silcd/packet_send.c.
695 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
696 library. Affected file lib/silcclient/client_notify.c.
698 * Added UMODE announcements. Affected file silcd/server.c.
700 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
702 * Memory leak fixes in:
704 lib/silcutil/silcsockconn.c
705 lib/silcske/silcske.c
708 lib/silccrypt/silcpkcs.c
709 lib/silccore/silccommand.c
710 lib/silccore/silcidcache.c
715 * ROBOdoc documented the lib/silcske/groups.h file and a
716 bit changed the interface for better.
718 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
720 * Update the client entry context in the ID cache after
721 nick change. Affected file lib/silcclient/command.c.
722 Fixes the CUMODE command when regaining founder privileges,
723 and a little WHOIS problem.
725 * Fixed silc_net_gethostbyname to correctly call the
726 inet_ntop. Affected file lib/silcutil/silcnet.c.
728 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
730 * Added IPv6 support checking to the configure.in.pre, added
731 also --enable-ipv6 option to override the check. Affected
732 file configure.in.pre.
734 * The silc_thread_create now calls the start function
735 directly if threads support is not compiled in. Removes
736 ugly #ifdef's from generic code. Affected files are
737 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
739 * Added silc_net_gethostby[name/addr]_async to asynchronously
740 resolve. Affected files are lib/silcutil/silcnet.[ch].
742 * Added support for rendering IPv6 based server, client and
743 channel IDs. Affected file lib/silcutil/silcutil.c.
745 * Added support for creating IPv6 based server IDs. Affected
746 file is silcd/serverid.c.
748 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
750 * Added silc_net_gethostby[addr/name] into the
751 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
752 routines. Added silc_net_is_ip[4/6]. Affected file is
753 lib/silcutil/unix/silcunixnet.c. All routines that take
754 address as argument now supports both IPv4 and IPv6 addresses.
756 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
758 * Fixed LIST command reply sending in server. Affected file
761 * Server now sends the kicker's client ID in the KICK notify
762 to the kicked client. Affected file silcd/command.c.
764 * The client library now parses the kickers client ID and
765 UI displays it. Affected files lib/silcclient/client_notify.c
766 and irssi/src/silc/core/silc-channels.c, module-formats.c.
768 * Made all payload parsing function prototypes consistent.
769 They all take now const unsigned char * and uint32 pair as
770 the payload data instead of SilcBuffer. Changes all around
771 the source tree. Other unsigned char* -> const unsigned char*
772 changes around the tree as well.
774 * Optimized SFTP client and server packet sending not to
775 allocate new buffer for each packet but to recycle the
776 first allocated buffer. Affected files are
777 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
779 * Optimized the SFTP client to use SilcList instead of
780 SilcDList for requests, because it is faster. Affected file
781 is lib/silcsftp/sftp_client.c.
783 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
784 into lib/silccore/silcid.[ch].
786 Renamed silcpayload.[ch] into silcargument.[ch].
788 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
790 * If client entry is deleted with active key agreement
791 session, abort the session.
793 The silc_client_abort_key_agreement now calls the completion
794 callback with new SILC_KEY_AGREEMENT_ABORTED status.
796 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
799 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
801 * Don't use __restrict in older GCC's. Affected file is
802 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
804 * silc_net_localhost now attempts to reverse lookup the
805 IP/hostname. Affected file lib/silcutil/silcnet.c.
807 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
808 command. It can be used to gain founder privileges at
809 the same time when joining the channel.
811 Defined that the SILC_NOTIFY_TYPE_KICKED send the
812 kicker's client ID as well. Updated protocol specs.
814 Defined that the server must send SILC_COMMAND_IDENTIFY
815 command reply with error status to client who sent
816 private message with invalid client ID.
818 Updated the protocol specification.
820 * Added silc_server_send_command_reply to send any
821 command reply. Affected file silcd/packet_send.[ch].
823 * Added silc_id_payload_encode_data to encode ID payload
824 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
826 * The server now send IDENTIFY command reply with error
827 status if client ID in private message is invalid. Affected
828 file silcd/packet_receive.c.
830 * Save the server key file with server's IP address in
831 the filename instead of hostname. The affected file is
832 irssi/src/silc/core/client_ops.c.
834 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
836 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
839 * Added libtool support for compiling shared objects in
840 lib/silcsim. Affected file configure.in.pre and
841 lib/silcsim/Makefile.am. Original patch by cras.
843 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
845 * Pid file configuration, and server's config file fixes
846 patch by toma. Updated CREDITS file.
848 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
850 * Fixed silc_client_channel_message to not try to decrypt
851 the message twice if it resolved the destination client
852 information. This could cause of dropping one channel
853 message. Affected file lib/silcclient/client_channel.c.
855 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
857 * Added silc_client_run_one into lib/silcclient/silcapi.h and
858 lib/silcclient/client.c. This function is used when the SILC
859 Client is run under some other scheduler, or event loop or
860 main loop. On GUI applications, for example this may be
861 desired to used to run the client under the GUI application's
862 main loop. Typically the GUI application would register an
863 idle task that calls this function multiple times in a second
864 to quickly process the SILC specific data.
866 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
868 * Fixed silc_server_drop() for dropping the supplementary
869 groups as well, this could cause a security hole on some
872 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
874 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
877 * Write PID file after dropping privileges. Added -F option
878 to run server on foreground. A patch by debolaz.
879 Affected files silcd/server.c, silcd/silcd.c.
881 * Fixed MOTD to return the MOTD file server name. Affected
882 file silcd/command.c.
884 * Added INFO command reply handling to the Irssi SILC Client.
885 Affected file irssi/src/silc/core/client_ops.c.
887 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
889 * Fixed the silc_idcache_list_* routines to really support
890 the dynamic list. Fixes a crash. Affected file is
891 lib/silccore/silcidcache.c.
893 * Fixed the LIST command reply to really call LIST command's
894 pending callbacks. Affected file silcd/command_reply.c.
896 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
898 * Update conn->local_entry->nickname after giving NICK
899 command. Affected file lib/silcclient/command.c.
901 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
903 * Added the [pid] option to the silcd configuration file
905 Affected files: serverconfig.[ch] and silcd.c
907 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
909 * Save fingerprint in WHOIS command reply in server.
910 Affected file silcd/command_reply.c.
912 * Fixed NICK commands pending callback registration.
913 Affected file lib/silcclient/command.c.
915 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
917 * Use ++server->cmd_ident when sending commands in server,
918 instead of random number. Affected file silcd/command.c.
920 * Fixed GETKEY command reply to call actually GETKEY pending
921 command callbacks. Affected file silcd/command_reply.c.
923 * A bit stricter check for nicknames. Check for same nickname
924 in NICK command also. Affected file silcd/command.c.
926 * Do not call INFO command everytime client ID changes, only
927 during first connecting. Affected file lib/silcclient/client.c.
929 * Set the new nickname only after successful command reply for
930 NICK command is returned by server. Affected file
931 lib/silcclient/command.c.
933 * Remove nicknames from nicklist during server_signoff notify.
934 Should fix /NAMES bit more. The affected file is
935 irssi/src/silc/core/silc-channels.c.
937 * Added `fingerprint' field to the SilcIDListData in the
938 silcd/idlist.h to hold the fingerprint of the client's
941 Send the fingerprint of the client's public key in WHOIS
944 Affected files silcd/command.c, and silcd/idlist.[ch].
946 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
947 create fingerprint from given data.
949 * Show the fingerprint of the client's public key in WHOIS.
950 Affected files irssi/src/module-formats.[ch] and
951 irssi/src/silc/core/client_ops.c.
953 * Format the multiple same nicknames also during JOIN and
954 NICK_CHANGE notifys. Affected file is
955 lib/silcclient/client_notify.c.
957 * Do not print error on screen for invalid private message
958 payload since it can come if someone is sending private
959 messages with wrong key. Affected file
960 lib/silccore/silcprivate.c.
962 * Fixed multiple concurrent /PING crash. Affected file
963 lib/silcclient/command.c.
965 * Changed the wrong ID encoding. All IP addresses must be
966 in MSB first order in encoded format. They were encoded
967 wrong and was in LSB format. Affected files are
968 silcd/serverid.c, lib/silcutil/silcutil.c.
970 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
972 * Call the `connect' client operation through the scheduler
973 in case of error. Affected file lib/silcclient/client.c.
975 * Call the `failure' client operation even if the error
976 occurred locally during a protocol. Affected file is
977 lib/silcclient/protocol.c.
979 * Added support of sending LIST command to router from normal
980 server. This way normal server can get list of all channels
981 in the network too. Fixed the channel list sending in the
982 server too. Affected files are silcd/command.c, and
983 silcd/command_reply.[ch].
985 * Added silc_server_update_channels_by_server and
986 silc_server_remove_channels_by_server. They are used during
987 disconnection of primary router and in backup router protocol.
988 Affected file silcd/server_util.[ch], silcd/server.c and
989 silcd/server_backup.c.
991 * Fixed channel adding to global list in IDENTIFY command
992 reply in server. Affected file silcd/command_reply.c.
994 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
996 * If the incoming packet type is REKEY or REKEY_DONE process
997 that packet always synchronously. Fixes yet another MAC
998 failed error on slow (dialup) connections. Affected file
999 lib/silcclient/client.c and silcd/server.c.
1001 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1003 * Call check_version SKE callback for initiator too. Affected
1004 file lib/silcske/silcske.c.
1006 * Implemented fix for security hole found in the SKE that was
1007 fixed in the specification few days back; the initiator's
1008 public key is now added to the HASH value computation.
1009 Added backwards support for the old way of doing it too, for
1010 old clients and old servers. Affected file is
1011 lib/silcske/silcske.c.
1013 * Enabled mutual authentication by default in SKE. If initiator
1014 is not providing mutual authentication the responder will
1015 force it. This will provide the proof of posession of the
1016 private key for responder. The affected files are
1017 lib/silcclient/protocol.c and silcd/protocol.c.
1019 * Do not cache anymore the server's public key during SKE.
1020 We do mutual authentication so the proof of posession of
1021 private key is done, and if the server is authenticated in
1022 conn auth protocol with public key we must have the public
1023 key already. Affected file silcd/protocol.c.
1025 * Added new global debug variable: silc_debug_hexdump. If
1026 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1027 file lib/silcutil/silclog.[ch].
1029 * Fixed compilation warning due to char * -> const char *.
1030 Affected files lib/silcutil/silcnet.h, and
1031 lib/silccore/silcauth.[ch].
1033 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1035 * Fixed CMODE command when new channel key was created. If
1036 the creation failed the old key was removed. Next time giving
1037 same command would crash the server since the old key was
1038 freed already. Affected file silcd/command.c.
1040 * Fixed the silc_server_announce_get_channels to not crash
1041 on reconnect. Affected file silcd/server.c.
1043 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1045 * Added silc_log_set_debug_string function to set a regex
1046 string to match for debug output. Only the function names,
1047 or filenames matching the given debug string is actually
1048 printed. This way it is possible to filter out those debug
1049 strings that user is not interested in.
1051 Fixed a bug in silc_string_regexify.
1053 Affected files lib/silcutil/silclog.[ch], and
1054 lib/silcutil/unix/silcunixutil.c.
1056 * Changed the -d options in both server and Irssi SILC client
1057 to take the debug string as argument. Affected files
1058 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1060 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1062 * Added silc_hash_babbleprint to create a Bubble Babble
1063 Encoded fingerprint. The encoding is developed by Antti
1064 Huima (draft-huima-babble-01.txt), and it creates human
1065 readable strings out of binary data. Affected file
1066 lib/silccrypt/silchash.[ch].
1068 * Print the babble print now in addition of fingerprint as well
1069 in Irssi SILC client. Affected files are
1070 irssi/src/fe-common/silc/module-formats.[ch],
1071 irssi/src/fe-common/silc/core/client_ops.c.
1073 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1075 * Fixed a security problem found in SKE. The initiator's
1076 public key too is now added to the HASH hash value creation
1077 which is signed by the responder to create the SIGN value.
1078 This will prevent anyone in the middle to lie to the responder
1079 about the initiator's public key. If this is done now, the
1080 man in the middle will get caught. Updated the protocol
1083 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1085 * Better installation directory handling. Configure module
1086 paths and other paths automatically to example_silc* files
1087 in doc/. A patch by toma.
1089 * Fixed compiler warning from MPI library, and from SILC RNG.
1092 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1093 It can be configured with ./configure. A patch by toma.
1095 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1097 * Find correct make to use in prepare-clean. A patch by
1098 toma. Affected file prepare-clean.
1100 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1102 * Added irssi variables use_auto_addr, auto_bind_ip,
1103 auto_bind_port and auto_public_ip.
1105 * Changed the interface for silc_client_send_key_agreement
1106 in lib/silcclient/silcapi.h
1110 irssi/src/silc/core/silc-core.c
1112 lib/silcclient/silcapi.h
1113 irssi/src/silc/core/silc-channels.c
1114 lib/silcclient/client_keyagr.c
1117 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1119 * Added silc_pkcs_public_key_compare to compare two
1120 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1122 * Check that the client who set the founder mode on the
1123 channel is the same client that is giving the founder
1124 mode to itself. It is done by comparing the saved public
1125 key (it is saved even in the authentication is passphrase).

1134 client library. Affected file lib/silcclient/client.c.
1136 * Fixed the silc_client_packet_parse to not to increase
1137 the packet sequence number if the conn->sock and the
1138 current socket connection is not same. This can happen
1139 for example during key agreement when the conn includes
1140 multiple socket connections (listeners). Affected file
1141 lib/silcclient/client.c.
1143 * The sender of the file transfer request now provides also
1144 the pointer (listener) for the key exchange protocol. If
1145 the listener cannot be created then it sends empty key
1146 agreement and lets the receiver provide the listener.
1148 Added `local_ip' and `local_port' arguments to the
1149 silc_client_file_send. If they are provided they are used,
1150 if not then it will attempt to find local IP address, if
1151 not found or bind fails then the remote client will provide
1154 Affected files are lib/silcclient/client_ftp.c and
1155 lib/silcclient/silcapi.h.

1164 of the client's public key (if the proof of posession of the
1165 corresponding private key is verified by the server).
1166 Updated to the protocol specification.
1168 * Added support of receiving the client's public key's
1169 fingerprint in command reply in client library. Affected
1170 file is lib/silcclient/command_reply.c, and
1171 lib/silcclient/idlist.[ch].

1230 preserve the WHOWAS info for the client. Affected file
1231 silcd/server_util.c.
1233 * Fixed SERVER_SIGNOFF notify handling in the server. The
1234 server is now able to process incoming SERVER_SIGNOFF notify
1235 for a server that it doesn't even know about. It will remove
1236 the clients provided in the notify. Affected file
1237 silcd/packet_receive.c.
1239 * Check for partial packet in data queue after every packet that
1240 was found from the queue. Return and wait for more data if
1241 there is partial data in queue. Affected file is

1263 * Added silc_rng_global_get_byte_fast to get not-so-secure
1264 random data as fast as possible. Random data is read from
1265 /dev/urandom if available and from the SILC RNG if not
1266 available. It is used in padding generation. Affected file
1267 lib/silccrypt/silcrng.[ch].
1269 * All packets in client library are now processed synchronously.
1270 Optimized packet processing a lot. Affected file

1282 * Assure that silc_client_notify_by_server_resolve does not
1283 resolve the client information multiple times. If it cannot
1284 be found by the first it cannot be found at all. Affected
1285 file lib/silcclient/client_notify.c.
1287 * Fixed WHOWAS command reply calling. Affected file
1288 lib/silcclient/command_reply.c.
1290 * Removed all references to silc_idlist_get_client from the
1291 Irssi SILC client since that call is internal call used by
1292 the library. The Irssi SILC client will use now client
1293 retrieval functions found in silcapi.h.
1295 * Fixed a bug in resolving nickname info before sending
1296 private message. It used freed memory. Affected file
1297 irssi/src/silc/core/silc-servers.c.

1319 Affected file lib/silcutil/silcnet.[ch].
1321 * If key exchange or rekey protocol is active for a connection
1322 parse all packets syncronously since there might be packets
1323 in packet queue that we are not able to process without first
1324 processing packets before them. Affected file silcd/server,
1325 lib/silcclient/client.c.
1327 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1328 whether library should continue processing the packet.
1329 Affected file lib/silccore/silcpacket.h.

1402 * Call the silc_server_udpate_servers_by_server in the
1403 primary router that comes back online in the backup resuming
1404 protocol. Otherwise it routes packets wrong. Affected file
1405 silcd/server_util.[ch], silcd/server_backup.c.
1407 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1409 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1410 lib/silcutil/silcbuffmt.[ch].

1413 length. Affected file lib/silccore/silcpacket.[ch].
1415 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1416 length for maximum padding up to 128 bytes). Affected
1417 file lib/silccore/silcpacket.h.
1419 * Removed all backwards support for old 0.5.x MAC thingies.
1420 The SILC packet header change makes it impossible to be
1421 backwards compatible.
1423 * Send the ENDING packet with timeout in the backup resuming
1424 protocol. This is to assure that all routers has connected
1425 to the primary router. Affected file silcd/server_backup.c.
1427 * Changed the RNG to take the first IV from random data. It
1428 used to take it from zero actually. Changed the RNG also

1435 (the packet length) encrypted. Affected files aroung the
1436 code tree, lib/silccore/silcpacket.[ch]. Removed the
1437 SilcPacketCheckDecrypt callback. It is not needed anymore
1438 since the silc_packet_receive_process will determine now

1452 * Allow backup router to announce servers. All servers
1453 announced by backup router are added to the global list
1454 automatically. Update hte server's socket to our primary
1455 router also when backup router announces a server.
1456 Affected file silcd/packet_receive.c.
1458 * Do not update the client->router in the function
1459 silc_server_udpate_clients_by_server if the client is on
1460 global list. We might fail to find any specific server
1461 for locally connected clients and local cell clients. They
1462 should still use the `from' and not `to' as client->router.
1463 This fixes backup router resuming protocol. Affected file
1464 silcd/server_util.c.
1466 * Decrease channel statistics count only if the channel
1467 deletion worked. Affected files are silcd/server.c and
1468 silcd/server_util.c.
1470 * Added silc_server_update_servers_by_server to update origin
1471 of all server entries. Used during backup router protocol.

1488 to the router it came from. Affected file is
1489 silcd/packet_send.c. Fixed memory leak too.
1491 * Announce informations for incoming router connection, but
1492 only after checking if it is replaced by backup router.
1493 Affected file silcd/packet_receive.c.
1495 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1502 silcd/packet_send.c.
1504 * Fixed silc_server_send_notify_dest to set the broadcast
1505 flag. Fixed the silc_server_send_notify_topic to actually
1506 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1507 Affected file silcd/packet_send.c.
1509 * Changed the SFTP Filesystem interface. Changed the
1510 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1511 the filesystem operation function. The SilcSFTPFilesystem
1512 is now a context that is allocated by all filesystem allocation
1513 functions and it already includes the operations structure
1514 and filesystem specific context. It is given as argument
1515 now to the silc_sftp_server_start. This made the interface
1516 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1517 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1519 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1521 * Changed the backup router adding and getting interfaces
1522 in the server. The router that will be replaced by the

1584 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1585 in the server to indicate disabled entry. All data read
1586 from the connection will be ignored and no data is sent
1587 for entry that is disabled. Affected files are
1588 silcd/idlist.h, silcd/server.c.

1639 new packet type SILC_PACKET_FTP and defined File Transfer
1640 Payload. The mandatory file transfer protocol is SFTP
1641 (SSH File Transfer Protocol). Affected file in addition
1642 of the internet draft is lib/silccore/silcpacket.h.
1644 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1645 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1646 is used as part of backup router protocol when the primary
1647 router of the cell is back online and wishes to resume
1648 the position as primary router.
1650 * Redefined the MAC generation keys in the protocol. The
1651 same key is not used anymore in both direction. Both
1652 direction will now use different keys for sending and
1653 receiving. This fixes a potential security flaw. This
1654 change causes incompatibilities in the protocol.
1656 * Redefined also the MAC computation from the packet.
1657 An packet sequence number is now added to the MAC
1658 computation. This prevents possible replay attacks against
1659 the protocol. This change too causes incompatibilities
1662 Added `sequence' field to the SilcPacketContext to hold
1663 the current sequence number for the packet.
1665 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1667 * Added `created' field to the SilcIDListData in the file
1668 silcd/idlist.h to indicate the time when the entry was
1671 * Added `created' field to the SilcChannelEntry too. Affected
1672 file silcd/idlist.h.
1674 * Added `creation_time' aguments to all the announcement functions
1675 in the server. If it is provided then only the entries that
1676 was created after the provided time frame are actually
1677 announced. Affected file silcd/server.[ch].
1679 * The protocol says that the Channel ID's IP address must be
1680 based on the router's IP address. Added check for this in
1681 the silc_server_new_channel when processing incoming New Channel
1682 Payload. Affected file silcd/packet_receive.c.
1684 * Print out the correct version with --version in SILC client.
1685 Affected file irssi/src/silc/core/silc-core.c.
1687 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1689 * Fixed WHOWAS command to check for completnes of the client
1690 entry always, not just when the command is coming from client.
1691 Affected file silcd/command.c.
1693 * Added new function silc_server_packet_queue_purge to purge the
1694 outgoing data queue to the network. After the function returns
1695 it is guaranteed that the outgoing packet queue is empty.
1696 Affected file silcd/packet_send.[ch].
1698 * Purge the outgoing packet queue in the rekey protocol's final
1699 callback to assure that all rekey packets go to the network
1700 before quitting the protocol. Affected file silcd/server.c.
1702 * Added silc_client_packet_queue_parse as similar function as
1703 in server to the client library. The affected file is
1704 lib/silcclient/client.c.
1706 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1708 * Splitted silcd/server.c and created silcd/server_util.[ch]
1709 for utility functions.
1711 * Added new socket flag SILC_SF_DISABLED to indicate that the
1712 connection is open but nothing can be sent to or received from
1713 the connection. Affected file lib/silcutil/silsockconn.[ch].
1714 The checking for disabled socket is checked in the low level
1715 silc_socket_write and silc_socket_read functions.
1717 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1719 * Allow only nicknames and channel names that fits into the
1720 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1722 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1724 * When processing JOIN command reply in server check that if
1725 the channel exists in our global list we'll move it the local
1726 list. Affected file silcd/command_reply.c.
1728 * Fixed the check whether client is joined on the channel already
1729 in JOIN command. Affected file lib/silcclient/command.c.
1731 * Fixed the JOIN command reply to check whether the channel
1732 already exists. Affected file lib/silcclient/command_reply.c.
1734 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1736 * Added silc_ske_status_string to map the SKE error numbers
1737 to readable strings. The affected files are
1738 lib/silcske/silcske[_status].[ch].
1740 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1742 * Do not show the private channels on the WHOIS channel list
1743 as it is not allowed by the protocol. The affected file is
1746 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1748 * Assure that the packet length digged from the actual packet
1749 is something sensible in the silc_packet_decrypt_rest_special
1750 in lib/silccrypt/silcpacket.c.
1752 * Free and NULL the allocated pointer in silc_hmac_alloc if
1753 the HMAC allocation fails. The affected file is
1754 lib/silccrypt/silchmac.c.
1756 * Print the selected security properties to the log files in
1757 the server. Affected file silcd/protocol.c.
1759 * Add SKE's reference counter even if calling the completion
1760 callback manually. Otherwise it goes negative, although it
1761 does not cause any problems. The affected file is
1762 lib/silcske/silcske.c.
1764 * Remove the client entry with short timeout after giving the
1765 KILL command. Affected file lib/silcclient/command.c.
1767 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1768 case all found clients are already disconnected (WHOWAS would
1769 found them) in the server. Affected file silcd/command.c.
1771 * Update the last_receive (time of last data received) to be
1772 updated only when received private or channel message so that
1773 the idle time showed in WHOIS makes more sense.
1775 * Added boolean field `valid' in to the SilcClientEntry in the
1776 client library to indicate whether the entry is valid or not.
1777 This fixes the nickname change bug on channel when changing
1778 the nickname to be same than the old (like nick to Nick) the
1779 nickname formatter doesn't set the new nick anymore to Nick@host.
1780 Affected file lib/silcclient/idlist.[ch].
1782 * Now actually fixed the nickname changing on disconnection.
1783 Added new function silc_change_nick to the Irssi SILC Client.
1784 Affected file irssi/src/silc/core/client_ops.c,
1785 irssi/src/silc/core/silc-nicklist.[ch].
1787 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1789 * Check that the public key exists in the GETKEY command before
1790 trying to encode it. Affected file silcd/command.c.
1792 * Print some notifications on received public keys with GETKEY
1793 command in the Irssi SILC Client. Affected files are
1794 irssi/src/fe-common/silc/module-formats.[ch],
1795 irssi/src/silc/core/client_ops.c.
1797 * Use IDENTIFY command to resolve the server information in the
1798 GETKEY command instead of INFO command. Affected file
1799 lib/silcclient/command.c.
1801 * All command reply functions in the client library now calls
1802 the pending command reply callbacks even if an error has
1803 occurred. The server has done this a long time and now it was
1804 time to move the client library to this as well. Now all
1805 errors can be delivered back to the pending command reply
1806 callbacks if necessary. Affected files are
1807 lib/silcclient/command[_reply].[ch].
1809 * Change the nickname on disconnection back to the username
1810 because in reconnect the server will enforce it to it anyway.
1811 Affected file irssi/src/silc/core/silc-servers.c.
1813 * Fixed a config file parsing bug in the Irssi SILC client.
1814 Affected file irssi/src/silc/core/clientconfig.c.
1816 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1818 * When printing the channel mode on JOIN, verify that the
1819 channel key and channel's HMAC are valid. Affected file
1820 irssi/src/silc/core/client_ops.c.
1822 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1824 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1825 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1826 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1828 * Removed channel key rekey task deleting from the function
1829 silc_server_save_channel_key. Affected file silcd/server.c.
1830 Added explicit timeout task context instead that is used to
1831 delete the task if we are registering a new task before the
1832 new task has elapsed.
1834 * When channel key rekey occurs the client library now saves
1835 the old channel key for a short period of time (10 seconds) and
1836 is able to use it in case some is still sending channel
1837 messages encrypted with the old key after the rekey. Affected
1838 file lib/silcclient/[idlist.h|client_channel.c].
1840 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1842 * Added check to the silc_server_new_id_real to not accept
1843 new ID if it is the sender's own ID. Affected file is
1844 silcd/packet_receive.c.
1846 * Assure that we do not announce ourself or the one we've
1847 sending our announcements when we're router and are announcing
1848 servers to our primary router. Affected file silcd/server.c.
1850 * Fixed silc_server_command_identify_check_client to assemble
1851 correct WHOIS packet. It send corrupted WHOIS packet and
1852 caused problem with router to router connections. Affected
1853 file silcd/command.c.
1855 Fixed also silc_server_command_whois_check the same way
1856 as for the IDENTIFY command.
1858 * Added new SilcIDListStatus to the server in the SilcIDListData
1859 structure. The status now includes the current status of
1860 the entry (like registered, resolved etc.). Affected file
1861 silcd/idlist.[ch]. Defined a bunch of different status types
1862 as well. This replaced the old boolean registered field as well.
1864 Added resolve_cmd_ident field to the SilcClientEntry structure
1865 too so that if the entry is for example being resolved so
1866 another command may attach to the same pending command reply
1867 without requiring to resolve the same entry again. This concept
1868 should optimize the WHOIS and the IDENTIFY resolving under
1869 heavy load by taking away unnecessary resolving for entries
1870 that are being resolved already.
1872 Added support for adding multiple pending commands for one
1873 command idenfier. Affected file silcd/command[_reply].[ch].
1875 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1876 before deleting the data. Otherwise the hash table will have
1877 freed data in comparison functions. Affected file is
1878 silcd/command_reply.c.
1880 * Fixed silc_idlist_replace_client_id to add the new entry to
1881 the cache with NULL nickname. Otherwise there will be invalid
1882 memory as the nickname after the nickname is freed. Affected
1883 file silcd/packet_receive.c.
1885 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1886 saved into wrong slots because the previous number of entries
1887 was not taken into account. Affected file silcd/idlist.c.
1888 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1890 * If we are router and we receive JOIN notify to a channel that
1891 does not have any users then notified client is marked as the
1892 channel founder, as it is it. The affected file is
1893 silcd/packet_receive.c
1895 * Added to the extended hash table API's table_del_*ext functions
1896 the destructor as argument too, so that the caller can decide
1897 which destructor to use or whether to use destructor at all.
1898 Affected file lib/silcutil/silchashtable.[ch].
1900 * Fixed ID Cache purging. It actually deleted the entries from
1901 the hash table after the data was freed. The hash table ended
1902 up comparing freed memory. The affected file is
1903 lib/silccore/silcidcache.c.
1905 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1907 * Fixed Irssi SILC client's KILL command's HELP syntax.
1909 * The USERS command now resolves the detailed user information
1910 if the userinfo field is missing. Affected file is
1911 lib/silcclient/command_reply.c.
1913 * Do not print error in silc_file_read if the read file does
1914 not exist. Just silently return NULL. Affected file is
1915 lib/silcutil/silcutil.c.
1917 * Fixed the silc_log_output to not wine about NULL filename
1918 and to not create some bogus " " filename. Affected file is
1919 lib/silcutil/silclog.c.
1921 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1923 * Fixed various printing bugs on the user interface in the
1924 Irssi SILC Client. Minor changes that were forgotten from
1927 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1929 * Fixed the configure.in.pre and the compilation and distribution
1930 environment to support the new autoconf 2.52. That version is
1931 now required to compile the CVS trunk.
1933 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1935 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1936 to generally parse user@fqdn format strings. Affected file
1937 lib/silcutil/silcutil.c.
1939 * Added nickname_format and nickname_force_format fields to the
1940 SilcClientParams structure. The first one defines the format
1941 for the nicknames that the library will enforce if the receives
1942 multiple same nicknames. The second one is boolean value and
1943 can be used to force the library to always enforce the format
1944 to the nicknames regardles whether there are multiple nicknames
1945 or not. This configurable formatting was employed to flexibly
1946 support accessing multiple nicknames from the user interface.
1947 The userinterface can now set the nicknames to what ever format
1948 they prefer. Affected file lib/silcclient/silcapi.h.
1950 Added function silc_client_nickname_format to the file
1951 lib/silcclient/idlist.c. It performs the nickname formatting.
1953 Added new field `hostname´ to the SilcClientEntry context.
1954 It holds the hostname of the client. Affected file is
1955 lib/silcclient/idlist.h.
1957 * Irssi SILC Client sets the nicknames in nick@hostn format.
1958 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1959 irssi/src/silc/core/silc-core.c.
1961 The WHOIS printing now also shows both the real nickname and
1962 the formatted nickname so that user knows how to access the
1963 user if there are multiple same nicknames cached. Affected
1964 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1965 printing formatting too to take the hostname now as a separate
1966 argument. The Affected file is
1967 irssi/src/fe-common/silc/modules-formats.[ch].
1969 * Changed the silc_client_get_clients_local to accept the formatted
1970 nickname as argument. It accepts the real nickname too but the
1971 formatted nickname can be used to find the true entry from
1972 multiple entries. Affected file lib/silcclient/silcapi.h and
1973 lib/silcclient/idlist.c.
1975 * Added nickname_format_parse field to the SilcClientParams.
1976 It is a callback function provided by the application to parse
1977 the nickname out of the formatted nickname string. The library
1978 calls it to get the nickname from the formatted string. Since
1979 the application generally knows better the format of the nickname
1980 string it parses it instead of the library, even though library
1981 encodes the formatted string. If the callback function is not
1982 provided then the library will use the string as is. The
1983 affected file is lib/silcclient/silcapi.h.
1985 * All the nickname strings passed to the client library in
1986 commands are now expected to be formatted nickname strings.
1987 If the command does not support the formatted nickname string
1988 it will assume that the sent string is the actual nickname.
1989 Affected file lib/silcclient/command.c.
1991 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1993 * Added public key authentication support to OPER and SILCOPER
1994 commands in the client library. Affected file is
1995 lib/silcclient/command.c.
1997 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1999 * Changed the get_auth_methdod client operation to be asynchronous.
2000 It can be async if the application resolves the authentication
2001 method from the server during the negotiation. Added new
2002 SilcGetAuthMeth completion callback that the application will
2003 call after resolving the authentication method.
2005 Added function silc_client_request_authentication_method that
2006 the application can use to resolve the authentication method
2007 from the server. Added also SilcConnectionAuthRequest callback
2008 that the library will call after the server has replied. The
2009 application can call this function if it does not know the
2010 current authentication method.
2012 Affected files are lib/silcclient/client.c and
2013 lib/silcclient/silcapi.h.
2015 * The Irssi SILC client now automatically resolves the authentication
2016 method incase any configuration information is not present (and
2017 currently there never is). The affected file is
2018 irssi/src/silc/core/client_ops.c.
2020 * Fixed public key authentication from the client library.
2021 Affected file lib/silcclient/protocol.c. Changed also the
2022 protocol specification about the public key authentication in
2023 the connection authentication protocol. The actual data to be
2024 signed is now computed with a hash function before signing.
2026 * Fixed the public key authentication from the server as well.
2027 Affected file silcd/protocol.c.
2029 * Removed the mlock()'s from the memory allocation routines.
2030 Affected file lib/silcutil/silcmemory.c. The ./configure does
2031 not check anymore for the mlock(). Affected file is
2034 * Fixed USERS command in server to allow the execution of the
2035 command for private and secret channels if the client sending
2036 the command is on the channel. Affected file silcd/command.c.
2038 * Fixed silc_client_get_clients_local to return the clients
2039 count correctly. It could return wrong value. Affected file
2040 lib/silcclient/idlist.c.
2042 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2044 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2045 types. The assembler optimizations seemed not to like 64-bit
2046 data types. The assmebler optimizations thus are now enabled
2047 also for BSD systems as opposed to only enable them for Linux.
2049 * Do not check for threads at all on BSD systems. Affected
2050 file configure.in.pre.
2052 * Removed -n and -h options from the Irssi SILC Client since
2053 they are not used in silc.
2055 * Fixed the prime generation to assure that the first digit
2056 of the generated random number is not zero since our conversion
2057 routines does not like number strings that starts with zero
2058 digit. If zero digit is seen the random number is regenerated.
2059 This caused some corrupted RSA keys when the zero first digit
2060 was met. Affected file lib/silcmath/silcprimegen.c.
2062 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2064 * Fixed WIN32 configuration in the ./configure script.
2065 Fixed to include xti.h on environments that has it.
2066 Patches by Carsten Ilchmann and andrew.
2068 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2070 * Changed the silc_id_create_client_id to be collision
2071 resistant. It is now assured that there cannot be created
2072 two same client ID's. I suspect that some weird bugs in
2073 the server were actually caused by duplicate Client IDs.
2074 Affected file silcd/serverid.[ch]. A router receiving
2075 new ID now also assures and informs the sending server
2076 if the ID caused collision.
2078 * Changed the silc_id_create_channel_id to also assure that
2079 there are no collisions.
2081 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2083 * Statement about ignoring the Mutual Authentication flag when
2084 performing rekey with PFS was a bit misleading. It is ignored
2085 if it was set in the initial negotiation, it cannot be even
2086 set in the rekey. Fixed in the ke-auth draft. Started the
2087 new versions of the protocol drafts in the doc/.
2089 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2091 * Fixed a bug in silc_client_command_identify_save when saving
2092 new channel information. The channel name was no duplicated
2093 and caused crash on exit. Affected file is
2094 lib/silcclient/command_reply.c.
2096 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2098 * Fixed the getkey command handling in the server. Send just
2099 empty OK reply to the sender if the key could not be fetched
2100 (but everything else was ok, like the key just was not available).
2101 Changed the public key parameter to optional in the protocol
2102 specs so that empty OK reply can be sent. Affected file
2105 Added a message to Irssi SILC client to tell to user if the
2106 server did not return a public key.
2108 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2110 * Fixed a channel key regeneration bug. It registered new
2111 timeout tasks exponentially until all system resources were
2112 used. Affected file silcd/server.c.
2114 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2116 * Added the SILC Document generator to the scripts/silcdoc.
2117 It can be used to generate the Toolkit Reference Manual out
2118 of the source tree. Internally it will also use the RoboDoc
2119 generator now imported in util/robodoc.
2121 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2123 * Added couple of return's in rekey protocol if error orccurred
2124 during the protocol. The execution must be terminated.
2125 Affected file silcd/protocol.c. Also, terminate the protocol
2126 always with timeout.
2128 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2130 * The client's Client ID was created initally from the wrong
2131 nickname (it could have been in format nick@host) in the
2132 silc_server_new_client. Affected file silcd/packet_receive.c
2134 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2136 * Added some SILC_LOG_ERROR's to various error conditions
2137 if client could not be added to ID cache. Affected files
2138 silcd/packet_receive.c and silcd/server.c.
2140 * When client's sock->user_data is freed, NULL also the
2141 client->router and client->connection pointers. Added check
2142 for these pointers being NULL to various places around the
2143 code. Affected file silcd/server.c.
2145 * Added client->data.registered == TRUE checks to various
2146 places around the code to assure that unregistered client's
2147 are not handled when it is not allowed. Affected file
2150 * Added `bool registered' fields to all
2151 silc_idlist_[server|client]_get_* routines to indicate whether
2152 the fetched client needs to be registered or not. Affected
2153 file silcd/idlist.[ch].
2155 * Add your own entry as registered to the ID cache in the
2156 server. Affected file server.c.
2158 * Fixed a bug in silc_server_new_server. The SilcServer was
2159 set as the new server's context instead of SilcServerEntry.
2160 This naturally caused some weird bugs.
2162 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2164 * Do not delete the channel rekey task when adding it
2165 for in silc_server_create_channel_key.
2167 * Changed the silc_server_create_channel_key to return
2168 TRUE or FALSE to indicate the success of the channel key
2171 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2173 * Fixed MSVC++ project files and added missing files to

2182 * Fixed buffer overflow from Irssi SILC Client. Affected
2183 file irssi/src/fe-common/core/themes.c.
2185 * Fixed double free in client library in the file
2186 lib/silcclient/client.c when disconnecting from server.
2188 * Applied double free patch from cras to Irssi SILC client.
2189 Affected files irssi/src/core/[modules/expandos].c
2191 * Fixed the disconnection handling to Irssi SILC Client.
2192 The application must call silc_client_close_connection
2193 in ops->connect client operation in case of failure of
2194 the connection. Affected file is
2195 irssi/src/silc/core/client_ops.c.
2197 * Do not set sock->protocol to NULL in the function
2198 silc_client_close_connection after executing the protocol's
2199 final callback since the sock might not be valid anymore.
2200 Affected file lib/silcclient/client.c.
2202 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2204 * Do not enable SILC_THREADS if the linking with libpthread
2205 did not happen. Affected file configure.in.pre.
2207 * Added notion to protocol specification that server must
2208 verify the sent authentication payload with CMODE when
2209 setting the channel founder key. Implemented it to the
2210 server. Affected file silcd/command.c.
2212 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2214 * Added _EXTRA_DIST SILC distribution variable to the
2215 distributions file. It is used to conditionally add extra
2216 files or directories to the specific distribution. Affected
2217 files ./prepare, Makefile.am.pre and distributions.
2219 Removed the `_' from the start of the distribution names.
2222 * Added README.WIN32 for instructions to compile the Toolkit
2225 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2227 * Fixed a double free in disconnection in the server. Affected
2228 file is silcd/server.c.
2230 * Fixed the lib/silcske/groups.c to work now also with GMP
2231 MP library. The string conversion did not work when using
2232 specific base and the base is indicated in the string as well.
2234 * Created win32/ directory which now includes MSVC++ specific
2235 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2236 It will appear only in the toolkit distribution
2238 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2240 * Changed the key material distribution function in case when
2241 the hash output is too short. The data is now concatenated
2242 a bit differently than it used to. Made the change to the
2243 SKE protocol specification.
2245 * Added better GMP detection to configure.in.pre. A patch
2248 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2250 * Fixed a minor bug in SKE that might cause some problem on
2251 some platforms. Affected file lib/silcske/silcske.c.
2253 * Added the cookie checking for initiator in the SKE. It checks
2254 that the responder returns the sent cookie unmodified. The
2255 affected file is lib/silcske/silcske.c. Added new SKE
2256 error type INVALID_COOKIE that can be sent during the
2257 negotiation. Fixed some memory leaks as well.
2259 * Added the "invalid cookie" error message to Irssi SILC client's
2262 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2264 * Added `task_max' field to the SilcClientParams to indicate
2265 the maximum tasks the scheduler can handle. If set to zero,
2266 default values are used. Affected file lib/silcclient/silcapi.h.
2268 * Fixed memory leaks in silc_client_close_connection. Affected
2269 file lib/silcclient/client.c.
2271 * Added silc_client_del_client_entry to client library to free
2272 all memory of given client entry. Affected file is
2273 lib/silcclient/idlist.[ch].
2275 * Added new functions silc_client_del_channel and
2276 silc_client_del_server to delete channel and server entries.
2277 Affected file lib/silcclient/[silcapi.h/idlist.c].
2279 * Removed silc_client_del_client_by_id from silcapi.h.
2281 * Fixed the INFO command to return the server's own info
2282 correctly when querying by Server ID. Affected file is
2285 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2287 * Removed the non-blocking settings in WIN32 code in the
2288 silc_sock_[read/write] and added SleepEx instead. Affected
2289 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2290 of input data is now checked with FIONREAD and ioctlsocket.
2292 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2294 * Call silc_schedule_task_del_by_context in the
2295 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2296 Affected file lib/silccore/silcprotocol.c.
2298 * Call silc_protocol_cancel for active protocols in the
2299 silc_server_close_connection if the funtion
2300 silc_server_free_sock_user_data has not been called.
2301 Affected file silcd/server.c.
2303 * Generic tasks cannot be deleted using the del_by_fd
2304 task deleting function since generic tasks does not match
2305 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2307 * Added a notion to SILCOPER help file that the SILCOPER works
2308 only on router server, not on normal server.
2310 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2312 * Added for WIN32 support for the new scheduler as well.
2313 Affected file lib/silcutil/win32/silcwin32schedule.c.
2315 * Fixed the SHA1 implementation to work on various platforms.
2317 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2319 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2320 API. It is part of the scheduler now. Everything else is
2321 as previously but some functions has changed their names.
2322 Checkout the lib/silcutil/silcschedule.h for the interface.
2323 Updated all applications to use the new interface. Affected
2324 files are lib/silcutil/silcschedule.[ch].
2326 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2328 * Found a bug in the SKE implementation. The HASH value,
2329 specified by the protocol, was not computed correctly. The
2330 public key of the responder was not added to the computation
2331 even though it is mandatory. Affected file lib/silcske/silcske.c.
2332 This unfortunately causes incompatibilities with older
2333 clients and servers.
2335 * Added WIN32 specific network init and uninit functions:
2336 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2337 the Winsock2. Affected file lib/silcutil/silcnet.h and
2338 lib/silcutil/win32/silcwin32net.c.
2340 * Set the socket always to nonblocking mode on WIN32 after
2341 reading data or writing data. Affected file is
2342 lib/silcutil/win32/silcwin32sockconn.c.
2344 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2346 * Fixed various compilation problems under WIN32. Affected
2347 files lib/silcutil/win32/silcwin32thread.c and
2348 lib/silcutil/win32/silcwin32schedule.c.
2350 * Removed all _internal.h #includes from public header
2351 files. Internal headers must never be included from
2354 Removed also the lib/silcske/payload_internal.h file.
2356 * All include files that may be needed (public and some others
2357 included by the public headers) by application developers are
2358 now copied to the ./includes directory. It does not copy any
2359 internal headers. Affected file Makefile.defines.pre and all
2360 Makefile.am's under lib/ and subdirs.
2362 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2364 * Do not change the ~/.silc directory's permissions automatically.
2365 Affected file irssi/src/silc/core/clientutil.c.
2367 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Do not cancel the protocol in silc_server_close_connection
2370 it might cause recursion. Now cancelled in the function
2371 silc_server_free_sock_user_data. Affected file silcd/server.c.
2373 * Fixed the silc_server_remove_clients_by_server to regenerate
2374 the channel keys correctly finally. Added also new function
2375 silc_server_remove_clients_channels to actually do it.
2376 Affected file silcd/server.c.
2378 * Fixed the silc_server_new_channel to not crash by giving
2379 wrong router to the new channel. Affected file is
2380 silcd/packet_receive.c.
2382 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2384 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2385 which is given as argument to the silc_client_alloc now.
2386 It can be used to configure the client and set various parameters
2387 that affect the function of the client.
2389 * The USERS command in server did not check whether the channel
2390 is private or secret. Affected file silcd/command.c.
2392 * Added new argument to the USERS command in protocol specification.
2393 The USERS command now can take the channel name as argument
2394 as well. Added support for this in client and server and
2395 updated the protocol specs.
2397 * Completed the GETKEY command in client. It can be now used
2398 to fetch also servers public key not only some clients.
2399 Affected files lib/silcclient/command[_reply].c.
2401 * Added silc_client_get_server to return server entry by the
2402 server name. Affected files lib/silcclient/silcapi.h and
2405 * Redefined the IDENTIFY command in protocol specification to be
2406 more generic. It now can be used to query information about
2407 any entity in the SILC Network, including clients, servers and
2408 channels. The query may be based either the entity's name
2409 or the ID. Added support for this in both client and server.
2411 Affected files silcd/command.c and lib/silcclient/command.c
2412 and command_reply.c.
2414 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2415 the _from_client and _from_server functions. Affected file
2418 * Added silc_client_get_channel_by_id_resolve to the file
2419 lib/silcclient/silcapi.h to resolve channel information by
2420 its ID. Added also silc_client_get_channel_by_id that
2421 does not resolve it from the server.
2423 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2425 * Added SilcServerEntry context into the client library
2426 to represent one server. The INFO command now allocates
2427 these to save the resolved server info. For now on the
2428 client library will also keep information about servers,
2429 connected and resolved with INFO.
2431 The INFO command now allocates the SilcServerEntry context
2432 and saves the server info there. The COMMAND_REPLY in
2433 the INFO now returns the parameters to application in
2434 same order as defined in the protocol specification.
2436 The entries are cached in the client->server_cache.
2438 * The INFO command is now issued after received the Client ID
2439 from the server. Affected file lib/silcclient/client.c.
2441 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2442 to the application as the mode changer might be server.
2443 It is guaranteed that NULL is not returned anymore to the
2444 application. Affected file lib/silcclient/client_notify.c.
2446 The ID Type is now also passed to the application so that
2447 it can check whether the returned entry is SilcClientEntry
2450 Added new function silc_client_get_server_by_id to return
2451 the server entry by ID. Affected files are the
2452 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2454 * Do not create the channel in the Irssi SILC Client when issuing
2455 the JOIN command but when received the sucessful JOIN command
2456 reply. Otherwise the channel might get created even though we
2457 could not join it. The Affected file is
2458 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2460 * Fixed a channel joining bug in router. The router must also
2461 check the channel modes, invite and ban lists etc. when serving
2462 the JOIN command sent by normal server. Affected file is
2463 silcd/command.c. The router now resolves the client's
2464 information from the server who sent the JOIN command if it
2465 does not know it, and processes the JOIN command only after
2468 * Changed the SilcCommandCb to take new argument; void *context2.
2469 Affected file lib/silccore/silccommand.h
2471 The second argument in the command callbacks in the server now
2472 includes the SilcServerCommandReplyContext if the command was
2473 called as pending command callback from the command reply.
2474 Otherwise it is NULL. When called as pending the status of the
2475 command reply will be checked and if it was erronous the
2476 error will be sent to the original sender of the command.
2477 This way the client always receives the error messages even
2478 though the server was actually the one who received the error
2479 when it resent the command to router, for example. Affected
2480 files silcd/command[_reply].[ch].
2482 * Fixed sending WHOWAS command's error message to client if
2483 the requested client could not be found. It was missing.
2486 * Changed the CMODE and CUMODE commands reply arguments in the
2487 protocol specification. The Channel ID is now sent in both
2488 of the commands to identify the channel. Implemented this
2489 new feature to the client and server. Affected files
2490 lib/silcclient/command_reply.c and silcd/command.c.
2492 * Made better checks for invite and ban lists in the JOIN
2493 command in server. Affected file silcd/command.c.
2495 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2497 * The server now performs the incoming host IP/DNS lookup
2498 using the silc_socket_host_lookup and thus does not block
2499 the server anymore. Affected file silcd/server.c.
2501 * Completed the multi-thread support for SILC Scheduler in
2502 the lib/silcutil/silcschedule.c.
2504 * Fixed the configure.in.pre to detect the pthread correctly
2507 * Fixed a deadlock in silc_task_queue_wakeup in the file
2508 lib/silcutil/silctask.c.
2510 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2512 * Added new function silc_schedule_wakeup that is used in
2513 multi-threaded environment to wakeup the main thread's
2514 schduler. It needs to be used when a thread adds a new task
2515 or removes a task from task queues. After waking up, the
2516 scheduler will detect the task queue changes. If threads
2517 support is not compiled in this function has no effect.
2518 Implemented the wakeup mechanism to both Unix and WIN32
2519 systems. Affected files are lib/silcutil/silcschedule.[ch],
2520 lib/silcutil/unix/silcunixschedule.c and the
2521 lib/silcutil/win32/silcwin32schedule.c.
2523 * Added new function silc_task_queue_wakeup to wakeup the
2524 scheduler by the specified task queue. Affected file
2525 lib/silcutil/silctask.[ch].
2527 * The silc_socket_host_lookup_start now wakes up the scheduler
2528 after adding the timeout task. Affected file is
2529 lib/silcutil/silcsockconn.c.
2531 * The silc_socket_host_lookup is synchronous now if the threads
2532 support is not compiled in. However, the callback is still
2533 called asyncronously through the scheduler, anyway. Affected
2534 file lib/silcutil/silcsockconn.c.
2536 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2538 * Added new function silc_socket_host_lookup to perform
2539 asynchronous IP and FQDN lookups for the socket connection.
2540 Affected files lib/silcutil/silcsockconn.[ch].
2542 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2544 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2545 that may or may not compile the mutex support in.
2547 Changed the silc_mutex_alloc interface. It allocates the
2548 mutex now to the sent pointer and returns TRUE or FALSE.
2550 Affected file lib/silcutil/silcmutex.h.
2552 * Wrote the SILC Task Queue interface to support multi-threads.
2553 Affected file lib/silcutil/silctask.[ch].
2555 * Wrote the SILC Scheduler to support multi-threads. Affected
2556 file lib/silcutil/silcschedule.c.
2558 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2560 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2561 in lib/silcutil/win32/.
2563 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2565 * Defined SILC Mutex API and SILC Thread API and implemented
2566 them for Unix. Affected files are
2567 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2568 lib/silcutil/unix/silcunixmutex.c and
2569 lib/silcutil/unix/silcunixthread.c.
2571 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2573 * Fixed the silc_server_remove_clients_by_server's channel
2574 key re-generation. The hash table handling was incorrect
2575 and would not work with many channels. Affected file is
2578 * Fixed some memory leaks around the server code.
2580 * Rewrote the silc_server_get_users_on_channel to support IPv6
2581 based Client ID's. Affected file silcd/server.c.
2583 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2584 specification. However, a separate document must be written
2585 to define the detailed signing procedure and the payload
2586 associated with the flag. Defined the flag to the
2587 lib/silccore/silcchannel.h as well.
2589 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2591 * Changed the dynamic tables to static size tables in the
2592 lib/silccrypt/silchmac.c.
2594 * Removed GCC dependencies from the code. A patch by cras.
2596 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2598 * Do not show the error "Error receiving packet bla bla"
2599 in server if it really was not an error (-2 means that reading
2600 is pending). Affected file silcd/server.c.
2602 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2604 * Fixed a possible crash in silc_server_remove_clients_by_server
2605 in silcd/server.c. Fixed there also some memory leaks.
2607 * Fixed the silc_idlist_replace_client_id. It could replace
2608 wrong key in the hash table. Affected file silcd/idlist.c.
2610 * Do not check whether there are global users on the channel
2611 if the channel->global_users is FALSE. Affected functions
2612 silc_server_remove_from_one_channel and
2613 silc_server_remove_from_channels in silcd/server.c. Also,
2614 do not check if the removed client is local as we can be
2615 sure that global client was not removed from the channel
2616 and checking for global users is not needed.
2618 * The silc_server_remove_clients_by_server now re-generates
2619 the channel keys correctly for those channels that had
2620 clients removed from them. Affected file silcd/server.c.
2622 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2624 * Found the reason of random crashes in the server. We weren't
2625 ignoring the SIGPIPE signal (which can be sent in write())
2626 and it crashed the server. Affected file silcd/silcd.c.
2628 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2630 * Assure that sock->user_data is not NULL in the function
2631 silc_server_packet_send in silcd/packet_send.c.
2633 * Disconnect the remote connection if it could not be added
2634 to any ID lists in the server. The affected file is
2637 * Check in silc_server_packet_send[_real/dest] that the
2638 socket is not disconnecting and ignore the data if it is.
2639 Affected file silcd/packet_send.c.
2641 * Define inline to __inline on native WIN32 compilation.
2642 Affected file includes/silcwin32.h.
2644 * Added some explicit type casts for inline code since MSVC
2645 require them. Affected files lib/silcutil/silcbuffer.h,
2646 lib/trq/silcdlist.h and lib/trq/silclist.h.
2648 * Print warning in log files from now on if the packet
2649 decryption fails. Affected file silcd/server.c.
2651 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2653 * Changed the `say' client operation's interface to accept
2654 new `type' argument to indicate the type of the message sent
2655 by the library. The application may filter the library's
2656 messages according the type. The affected file is the
2657 lib/silcclient/silcapi.h.
2659 * Added two new functions to lib/silcclient/silcapi.h:
2660 silc_client_del_client and silc_client_del_client_by_id.
2661 Affected file lib/silcclient/idlist.c.
2663 * Moved the clientincludes.h from includes/ to silc/ and
2664 serverincludes.h from includes/ to silcd/.
2666 * The modes for the CMODE and CUMODE are now passed as
2667 uint32 for application with COMMAND_REPLY. The affected
2668 file is lib/silcclient/command_reply.c.
2670 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2672 * /WHOIS without arguments shows client's own information.
2673 Affected file lib/silcclient/command.c.
2675 * Changed PING to not accept any arguments. The specs
2676 says that client can ping only the connected server so
2677 requiring an argument is not needed. Affected file is
2678 lib/silcclient/command.c.
2680 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2682 * Fixed a fatal bug in private message sending and reception
2683 encryption and decryption when using private message keys.
2684 The implementation was incorrect and did not follow the
2685 specification. It causd that some of the message were
2686 lost since it did not use the sending and receiving keys
2687 as the protocol suggests. This has been fixed and will cause
2688 incompatibilities with older clients when sending private
2689 message encrypted with private message keys. Affected files
2690 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2691 and various other in Irssi SILC Client.
2693 Added `responder' boolean argument to the functions
2694 silc_client_add_private_message_key[_ske] to indicate when
2695 the key is added as responder or initiator of the key
2698 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2700 * Removed the silc_ske_check_version function and created
2701 a SilcSKECheckVersion callback. Added also a function
2702 silc_ske_set_callbacks that is now used to set all SKE
2703 callbacks. The callback functions are not given to
2704 the SKE functions anymore, but this function is used to
2707 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2709 * Added `silc_version' argument to the silc_client_alloc
2710 to define the version of the application for the library.
2711 The library will use the version string to compare it
2712 against the remote host's (usually a server) version
2713 string. Affected file lib/silcclient/silcapi.h
2715 * Added the KE protocol context to Key Agreement context
2716 in client library so that we can abort the SKE if it
2717 is in process when we get timeout. Affected file is
2718 lib/silcclient/client_keyagr.c.
2720 * Do not resolve the client ID forever if it returns in the
2721 first time that such client does not exist. This was done
2722 for example with private message. Affected file is
2723 lib/silcclient/client_prvmsg.c.
2725 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2727 * Do not add regex.h for WIN32. The affected file
2728 includes/silcincludes.h.
2730 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2731 not work yet 100%. It generates the DLL's automatically
2732 when compiling with --with-win32 under cygwin.
2734 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2736 * lib/contrib/regex.c is not compiled on WIN32.
2738 * Added silc_net_get_socket_opt function to the
2739 lib/silcutil/silcnet.h.
2741 * Added includes/silcwin32.h for WIN32 specific includes
2744 * Do not use ptime structure or any of the posix process
2745 functions on WIN32 in lib/silccrypt/silrng.c.
2747 * Added silc_gettimeofday to provide generic function
2748 for struct timeval on all platforms. Added the function
2749 to lib/silcutil/silcutil.h.
2751 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2753 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2754 library as they clearly belong there. As a plus side we
2755 can make the actual socket connection routines platform
2758 Added also new generic function silc_socket_read and
2759 silc_socket_write (that used to be silc_packet_[read/write].
2760 The implementation of these are platform specific.
2762 * Added WIN32 specific routines of silc_socket_[read/write]
2763 to lib/silcutil/win32/silcwin32sockconn.c.
2765 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2767 * Added preliminary support for native WIN32 compilation under
2768 cygwin (using the -mno-cygwin option for GCC) to the
2769 ./configure.in.pre. The --with-win32 now prepares the
2770 compilation for native WIN32.
2772 * Rewrote the SILC Scheduler interface in the file
2773 lib/silcutil/silcschedule.h. The scheduler is now context
2774 based and does not have anymore any global static scheduler.
2775 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2776 and created lib/silcutil/win32 directory for WIN32 based
2779 * Added Unix specific network routines to the
2780 lib/silcutil/unix/silcunixnet.c and the old
2781 lib/silcutil/silcnet.c includes now only generic routines.
2783 Added WIN32 specific network routines to the
2784 lib/silcutil/win32/silcwin32net.c.
2786 * Added Unix specific utility functions from the
2787 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2789 * Added WIN32 SILC Scheduler to the file
2790 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2793 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2795 * Do not handle JOIN notify in the server if the target client
2796 is not registered (idata->registered == FALSE). The affected
2797 file is silcd/packet_receive.c.
2799 * Update the nickrec->founder in event_cumode in the Irssi SILC
2800 client. Affected file irssi/src/silc/core/silc-channels.c.
2802 * Fixed the CUMODE_CHANGE notify handling in the server when
2803 server and router are announcing their clients on channels.
2804 Now the mode changes are saved and notified correctly. The
2805 affected file is /silcd/packet_receive.c.
2807 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2808 They really did not replace the cache entry in the ID Cache.
2809 Now they do that. Affected file silcd/idlist.c.
2811 * Fixed the KICK notify handling in the Irssi SILC client to
2812 update the channel records so that the kicked client does not
2813 appear to be on the channel. The affected file is
2814 irssi/src/silc/core/silc-channels.c.
2816 * Always update the conn->current_channel when executing command
2817 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2819 * Fixed the KILL notify handling in Irssi SILC client to remove
2820 the killed client on all channels.
2822 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2824 * Fixed the silc_parse_command_line to remove extra spaces
2825 from the start and end of the arguments. Affected file is
2826 lib/silcutil/silcutil.c.
2828 * Cancel and free any active protocol in the function
2829 silc_server_close_connection. Affected file silcd/server.c.
2831 * Cancel and free any active protocol in the function
2832 silc_client_close_connction. Affected file is
2833 lib/silcclient/client.c.
2835 * Do not execute the KILL command for clients that are in
2836 history (ie. they are not in the network). Affected file is
2839 * Fixed KILL notify handling, client does not crash anymore.
2840 Affected file irssi/src/silc/core/silc-channels.c.
2842 * Reduced the default packet buffer size from 2048 to 1024 in
2843 lib/silccore/silcpacket.c.
2845 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2846 counter to the SKE context that is incresed when the SKE library
2847 performs async operation outside the library. If the outside
2848 process frees the SKE context and FREED status will be set
2849 and the library will detect after the sync operation that the
2850 libary is freed. The affected files are
2851 lib/silcske/silcske[_status].[ch].
2853 * Resolve the client entry information in the function
2854 silc_client_channel_message to assure that NULL pointer is not
2855 passed as client entry to the application. */
2857 * Fixed the task timeout calculation to assure that there is
2858 never negative timeouts. The affected file is
2859 lib/silcutil/silcschedule.c.
2861 * Fixed the channel user mode notification sending in server.
2862 It was sent point-to-point to the router (or to server by router)
2863 but it needs to be destined to a channel. The routines now
2864 supports sending the channel user mode notifys to the channels
2865 when announcing clients and channels. Affected files are
2866 silcd/server.c and silcd/packet_receive.c.
2868 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2869 It did not actually replace the old channel entry in the cache.
2870 Affected file lib/silcclient/client_notify.c.
2872 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2874 * Fixed a possible crash in silc_packet_send_prepare. It now
2875 assures always that there is enough space in the buffer and
2876 at the tail area of the buffer (for MAC).
2878 Fixed the inbound buffer reallocation in silc_packet_read.
2879 It was old code and did not handle the reallocation correctly.
2882 The affected file is lib/silccore/silcpacket.c.
2884 * Fixed buffer overflow in silc_parse_nickname in the file
2885 lib/silcutil/silcutil.c.
2887 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2889 * make install generates new server keys only if there is not
2892 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2894 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2895 Added check that if the NOREPLY is set then we will not send
2896 the away message. This avoids infinite loop of away messages
2897 if both clients are away. The affected file is
2898 lib/silcclient/client_prvmsg.c.
2900 * Fixed client crash if /NICK was given without arguments.
2901 Affected file lib/silcclient/command.c.
2903 * Server does not send the invite list in INVITE command back
2904 to the client if the list was not altered. Added this notion
2905 to the protocol spec as well. Affected file silcd/command.c.
2907 Fixed possible crash in INVITE command by checking the
2908 value of silc_server_get_client_route command.
2910 * Fixed the INVITE notify type handling. The arguments are now
2911 taken in correct order and client does not crash. The affected
2912 file is irssi/src/silc/core/silc-channels.c.
2914 Removed the "Inviting xxx to channel" message from the
2915 client library away and let the application handle it.
2916 Affected file lib/silcclient/command.c. Added that message
2917 to Irssi SILC client's message formats.
2919 * Fixed CMODE command crash in client. It now checks the
2920 amount of arguments correctly and does not crash. The affected
2921 file is lib/silcclient/command.c.
2923 * Do not create new channel automatically in silc_channels_join
2924 but check whether the channel by that name already exists.
2925 Affected file irssi/silc/core/silc-channels.c.
2927 * Do not send the SERVER_SIGNOFF to router if the disconnected
2928 entity was the router. Affected file silcd/server.c.
2930 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2931 SILC client as it was missing from there.
2933 Added the handling of the KICK notify to the Irssi SILC client
2934 as it was missing. Added "you have been kicked" message to
2935 Irssi SILC client's message modules formats.
2937 Added the handing of the KILL notify to the Irssi SILC client
2938 as it was missing. Added the kill message module formats
2941 The affected file is irssi/src/silc/core/silc-channels.c.
2943 * The router did not save the channel mode the server announced.
2944 Affected file silcd/packet_receive.c.
2946 * Fixed a possible crash in INFO command in server. If the
2947 server did not provide the server info it crashed. Affected
2948 file silcd/command.c.
2950 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2952 * Fixed the GETKEY command in the server to check also the
2953 global list. Otherwise the GETKEY would not work correctly
2954 in normal SILC server. Affected file silcd/command.c.
2956 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2958 * Fixed GETKEY crash, it crashed if the command did not succseed.
2960 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2962 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2963 is now real and not just an macro interface to GMP.
2965 Removed the entire GMP from the source tree and imported new
2966 NSS MPI library instead. Reason for removing GMP is that it is
2967 extremely large and compiles extremely slow. The NSS MPI
2968 is only a few files and compiles in less than 10 seconds.
2969 The speed is also about the same as GMP. The MPI is imported
2970 to lib/silcmath/mpi.
2972 If the system has GMP installed we will still use the GMP.
2973 If it is not then the NSS MPI will be compiled.
2975 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2977 * Merged a long nickname (127 characters long) crash bugfix from
2978 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2980 * Merged a freed memory reference bugfix from Irssi CVS tree.
2981 Affected file irssi/src/core/commands.c.
2983 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2985 * Added the server's public key sving and verification to the
2986 server when performing the SKE. This was missing and the
2987 remote server's (or router's) public key was accepted without
2988 checking whether we have it previously or trust it at all.
2989 Affected file silcd/protocol.c.
2991 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2993 * Check in the silc_server_timeout_remote if protocol is active
2994 and make sure that the protocol's final callback is called so
2995 that all memory if freed. Affected file silcd/server.c.
2997 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * silc_server_whois_send_reply crashed the server if the nickname
3000 was 127 characters long. Affected file silcd/command.c.
3002 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3004 * Added sanity check to the silc_server_new_client. If the hostname
3005 is provided inside username then check that the provided hostname
3006 really is the same as the resolved one. If the hostname was not
3007 resolved then check it from the public key. Affected file is
3008 silcd/packet_receive.c.
3010 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3011 if the server disconnected us and the connection is not valid
3012 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3014 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3015 the library to the lib/silcutil/silcutil.[ch].
3017 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3019 * Close log file after open. Affected file
3020 lib/silcutil/silclog.c.
3022 * Check whether sock == NULL in silc_client_send_packet and return
3023 if it is. Affected file lib/silcclient/silcclient.c.
3025 * Check rec->entry == NULL in the Irssi SILC Client before
3026 sending the channel message. Affecte file is
3027 irssi/src/silc/core/silc-servers.c.
3029 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3031 * Merged a splitted window bugfix from Irssi CVS tree. The
3032 affected file is irssi/src/fe-text/textbuffer-view.c.
3034 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3035 It did not print nickname.
3037 * Improved the distributions system a bit.
3039 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3041 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3042 irssi/src/fe-text/gui-window.c.
3044 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3045 to in-active server. The affected file is
3046 irssi/src/silc/core/client_ops.c.
3048 * Resolve the client in USERS command reply if the entry does
3049 not have username resolved. The affected file is
3050 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3051 command to WHOIS command to really resolve stuff. The USERS
3052 is not used any more in any critical section so WHOIS can
3053 be used even though it might be slower than IDENTIFY.
3055 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3058 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3060 * Changed the protocol API a bit more consistent in the
3061 lib/silccore/silcprotocol.[ch].
3063 * Changed the following headers to ROBODoc format:
3065 lib/silccore/silcpayload.h
3066 lib/silccore/silcprotocol.h
3067 lib/silccore/silcsockconn.h
3069 All core library headers are now formatted.
3071 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3073 * Fixed a bug in Irssi SILC client; do not show that you are
3074 server/router operator if you really are not. Affected file is
3075 irssi/src/silc/core/client_ops.c.
3077 * Renamed silc_command_free_payload to silc_command_payload_free.
3078 Affected file lib/silccore/silccommand.h
3080 * Added silcmath.h to include the prototoypes of various routines
3081 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3084 * Changed the following headers to ROBODoc format:
3086 lib/silccore/silcchannel.h
3087 lib/silccore/silccommand.h
3088 lib/silccore/silcid.h
3089 lib/silccore/silcidcache.h
3090 lib/silccore/silcmode.h
3091 lib/silccore/silcnotify.h
3092 lib/silccore/silcpacket.h
3093 lib/silcmath/silcmath.h
3095 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3097 * Added checking to the server code not to start the server if
3098 ciphers and stuff are not configured properly. Affected files
3099 silcd/serverconfig.[h] and silcd/server.c.
3101 * Changed the layout of the header files of the public interfaces
3102 in the SILC libraries. The new layout supports ROBODoc
3103 documentation tool (and some others) so that it is easy to create
3104 a library reference manual. All the other headers and source
3105 code must still follow the CodingStyle document. Also source
3106 code must not include these ROBODoc stuffs, only the headers.
3107 Furthermore, all public interface headers must now be named
3108 by using `silc' prefix, example: silcapi.h, silccipher.h.
3109 Some files were renamed due to this. All the other headers
3110 must not be used as public interfaces. I will update the
3111 CodingStyle document later. Changed following headers, so far:
3113 lib/silcclient/silcapi.h
3114 lib/silccore/silcauth.h
3115 lib/silccore/silcprivate.h
3116 lib/silccrypt/silcdh.h
3118 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3122 * Removed silc_client_packet_send_flush from the client library
3123 as it is not needed. Affected file lib/silcclient/client.[ch].
3125 * Added printing of message of unresolved authentication method
3126 to the Irssi SILC client. Added it to the module formats.
3127 Removed the same message from the client library.
3129 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3131 * Added new distribution feature, DISTLABEL. Every distribution
3132 can define own preprocessor label that can be used in the
3133 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3134 file distributions, acconfig.h.pre and prepare.
3136 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3138 * Added Makefile.defines_int to include the actual definitions
3139 for Makefile.defines.in. Tested the new distribution system,
3140 created distributions and tested installation.
3142 * Added AWAY message printing to the Irssi SILC client. Added
3143 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3145 * Added SCONNECT command to call the SILC's CONNECT command.
3146 Cannot use CONNECT directly since Irssi uses that internally.
3147 Affected file irssi/src/silc/core/silc-servers.c.
3149 Added ACTION local command. It is same as ME command but takes
3150 the channel as mandatory argument.
3152 Rewrote some of the Irssi's help files to suite for SILC
3155 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3157 * Added Makefile.defines[.in] that should for now on be included
3158 in all Makefile.am file in the source tree. That file includes
3159 all common compilation definitions for SILC source tree.
3161 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3163 * Minor changes to the ./prepare script to change the package
3164 name according the distribution name to the configure.in.
3166 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3168 * Created new distribution system. Added file `distributions'
3169 that defines all the distributions that can be created out of
3170 the SILC source tree. The ./prepare script now reads that
3171 file to determine how to prepare the distributions. The
3172 first argument to the ./prepare is the name of the distribution
3173 and second is the version of the distribution. If given
3174 without arguments it creates the default (toolkit) distribution
3175 with the default version (defined in ./prepare).
3177 All Makefile.am files that are subject to the distributions
3178 are now named as Makefile.am.pre. These are ./Makefile.am
3179 and lib/Makefile.am. Others may be changed later.
3181 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3183 * Added invite list, ban list, some key management and connection
3184 error message printing to module formats in the Irssi SILC client.
3186 * Added new silc_client_set_away_message to set the away message
3187 that is back to the person who sent private message. The
3188 affected file lib/silcclient/silcapi.h and the
3189 lib/silcclient/client_prvmsg.c.
3191 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3193 * Fixed the private message sending in the Irssi SILC client,
3194 added local command KEY to the Irssi SILC client.
3196 Added key management and key agreement message formats to the
3197 irssi/src/fe-common/silc/module-formats.[ch].
3199 Added USERS (alias WHO) printing, server/router operator
3200 indication and LIST command printing to the module formats.
3202 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3204 * Fixed channel joining notify handling, cumode notify handling
3205 from Irssi SILC client.
3207 * Added SILC specific module-formats to the Irssi SILC client so
3208 that SILC specific message hilighting, colors etc is possible.
3209 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3211 Added channel mode, channel user mode, actions, notices,
3212 whois and whowas printing to the the module-formats.c.
3214 * Fixed a bug in channel deletion in the server. The channel
3215 is not left to the cache even if the channel founder auth mode
3216 is set when there are no users anymore on the channel. Affected
3217 file silcd/server.c.
3219 * The silc_net_localhost now resolves the entire hostname including
3220 the domain name. Affected file lib/silcutil/silcnet.c.
3222 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3224 * Changed the ask_passphrase client operation to be ascynchronous.
3225 It has now a completion callback and a context that the
3226 application must call after it has got the passphrase from
3227 the user. Affected files lib/silcclient/silcapi.h,
3228 lib/silcclient/protocol.c, lib/silcclient/command.c and
3231 Added SilcAskPassphrase callback that the application calls
3232 to deliver the passphrase to the library.
3234 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3235 The public key verification and especially a certificate
3236 verification is asynchronous procedure.
3238 Added new SILC_SKE_STATUS_PENDING status to indicate the
3239 request is pending and a callback will be called to finalize
3242 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3243 indicate that remote end did not send its public key (or
3244 certificate), even though we require it. Added check for this
3245 condition in the SKE. This was a security bug, now fixed.
3247 Defined new SilcSKEVerifyCbCompletion callback that is called
3248 when the verification process is completed.
3250 The affected files lib/silcske/silcske_status.h and
3251 lib/silcske/silcske.[ch].
3253 * Changed the verify_public_key client operation to be async
3254 as well. Defined SilcVerifyPublicKey callback that is used to
3255 indicate the success of the public key verification process.
3257 Changed the server and client to use the new async client
3260 * Changed the Irssi SILC client's internal scheduler to be called
3261 twice as many times as it used to be. As a result the client
3262 should be a bit faster now. Affected file is
3263 irssi/src/silc/core/silc-core.c.
3265 * Added support to Irssi SILC client of asynchronous public key
3266 verification and passphrase inquiry. Affected file is
3267 irssi/src/silc/core/silc-core.c.
3269 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3271 * Do not say "You have left channel %s" in client library.
3272 Moved it to the application. Affected files are
3273 lib/silcclient/command.c and silc/client_ops.c.
3275 * Fixed silc_client_get_clients. Command context was not
3276 duplicated and was freed memory in the callback. Affected
3277 file lib/silcclient/idlist.c.
3279 * Do not say "you are now talking..." on JOIN command in the
3280 client library. The appliation must handle it.
3282 * Do not say ".. changed topic to" in command reply in the
3283 client libary. The application must handle it.
3285 * Fixed TOPIC command sending in the client library.
3287 * Fixed a memory leak in silc_client_command_free in the file
3288 lib/silcclient/command.c.
3290 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Imported a modified version of Irssi client to the source tree.
3293 The Irssi will be used to create a new client called
3294 Irssi SILC. Imported to irssi/.
3296 Added silc_core_init_finish function to the Irssi. Affected
3297 file irssi/configure.in.
3299 A lot changes in the Makefile.ams around the irssi tree.
3301 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3303 * Do not rehash if the new size is same as the old size of the
3304 hash table, in the silc_hash_table_rehash*. The affected file
3305 lib/silcutil/silchashtable.c.
3307 * Replaced hash_table_del_by_context calls from the server
3308 (when channel->user_list and client->channels) to the
3309 hash_table_del as it is sufficient and faster.
3311 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3313 * Added silc_hash_table_list, silc_hash_table_get and the
3314 SilcHashTableList structure to provide an alternative way to
3315 traverse the hash table. The affected files are
3316 lib/silcutil/silchashtable.[ch].
3318 * Changed the server's idlist routines to use the hash table
3319 routines to optimize the code.
3321 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3323 * Replaced the client entry's `channel' list and channel entry's
3324 `user_list' list to hash tables for optimized lookup. Changed
3325 the code to use the hash table interface around the code.
3326 Affected file lib/silcd/idlist.[ch].
3328 * Added `auto_rehash' boolean argument to the function
3329 silc_hash_table_alloc to indicate whether the hash table should
3330 auto-rehash when it thinks is appropriate time. It will
3331 increase the hash table size if the there is twice as much
3332 entries in the table than the size of the table, and will
3333 decrease the size if there are twice as less entries than
3334 the size of the table.
3336 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3338 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3340 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * silc_idcache_purge_by_context deletes the entry now by context
3343 as it is supposed to do. Affected file lib/silccore/idcache.c.
3345 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3346 client is not anymore valid (WHOWAS givens the info) and not
3347 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3349 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3351 * Removed the `data' and `data_len' arguments from the ID Cache
3352 interfaces and added `name' argument. ID Cache does not handle
3353 anymore the binary data only a names associated with given ID.
3355 * When hashing a Client ID with silc_hash_id the entire ID is
3356 not hashed anymore, instead only the hash of the Client ID is
3357 hashed. This way we can access the Client ID from the cache
3358 with Client ID but with the hash of the ID (which is a hash of
3359 the nickname) as well without any difference in performance.
3361 Added also silc_idcache_find_by_id_one_ext to do one on one
3362 searching when we have the actual ID. Added also function
3363 silc_hash_client_id_compare. The affected files are
3364 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3366 * When hashing the name associated with a ID it is always done
3367 in lowercase. This way we can access the cache without worrying
3368 about case-sensitivity, even though, for example nicknames are
3371 * Fixed a bug in server with channel message sending. It put
3372 wrong ID type as destination ID. The affected file
3373 silcd/packet_send.c.
3375 * silc_idcache_del_by_context now deletes from all hash tables
3376 by context. Affected file lib/silccore/idcache.c.
3378 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Changed the client library to use the new ID Cache interface.
3381 Changes around the source tree.
3383 * Added silc_hash_table_rehash_ext to rehash with specific
3384 hash function. Affected file lib/silcutil/silchashtable.[ch].
3386 * Added silc_hash_string_compare to compare two strings in the
3387 hash table. Affected file lib/silcutil/silcutil.[ch].
3389 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3391 * Added new function silc_idcache_del_by_context into the
3392 lib/silccore/idcache.[ch].
3394 * Changed the server's ID list routines to use the new ID Cache
3395 interface. Changes around the source tree.
3397 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3399 * Added silc_hash_table_del[_by_context]_ext functions in to the
3400 lib/silcutil/silchashtable.[ch].
3402 Removed silc_hash_table_find_all* routines and added new
3403 silc_hash_table_find_foreach to replace them.
3405 Added silc_hash_table_replace_ext function as extended
3406 replacing function. Separated the simple hash table interface
3407 from the extended hash table interface in the file
3408 lib/silcutil/silchashtable.h.
3410 * Fixed minor bugs and changed it to use some of the new
3411 hash table functions in lib/silccore/idcache.c
3413 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Added new function silc_hash_table_find_all to return all keys
3416 in the hash table by the specified key. As the hash table is
3417 collision resistant it also makes it possible to have several
3418 duplicate keys in the hash table. This function may be used to
3419 find all of the keys from the hash.
3421 Added user_context arguments to the SilcHashFunction,
3422 SilcHashCompare and SilcHashDestructor to deliver user specified
3425 Added new fuctions silc_hash_table_find[_all]_ext to do
3426 extended lookup with specified hash and compare functions and
3427 specified user contexts.
3429 Added new function silc_hash_table_add_ext to add the key
3430 with specified hash function and user context.
3432 Added new function silc_hash_table_foreach to traverse all
3433 entrys in the hash table. Added SilcHashForeach callback
3436 Added new function silc_hash_table_del_by_context to delete
3437 the entry only if the context associated with the key matches.
3439 Affected files are lib/silcutil/silchashtable.[ch].
3441 * Removed silc_hash_[server/client/channel]_id and added just
3442 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3443 silc_hash_id_compare to compare two ID's using as the hash table
3444 comparison function. Added also silc_hash_data to hash
3445 binary data and silc_hash_data_compare to compare it.
3447 * Removed silc_idlist_find_client_by_hash as it is not needed
3448 anymore. Affected file silcd/idlist.[ch].
3450 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3451 to use internally the SilcHashTable. The new ID Cache is a lot
3452 faster than the old one. Some of the ID Cache interface was also
3453 rewritten and obsolete and stupid functions were removed.
3455 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3457 * Added entry_count field to the SilcHashTable to keep the number
3458 of the entries in the table. Implemented the function
3459 silc_hash_table_rehash. Added new function
3460 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3462 Fixed a minor bug in silc_hash_table_free.
3464 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3465 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3466 into the lib/silcutil/silcutil.[ch].
3468 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Implemented a collision resistant hash table into the
3471 lib/silcutil/silchashtable[ch]. See the header and the source
3472 for the SilcHashTable API.
3474 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3476 * Merged dotconf version 1.0.2 into lib/dotconf.
3478 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3480 * Do not compile anything in lib/silcsim/* if the SIM support
3481 is not enabled. The tree should now compile without problems
3484 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3486 * Compiled the SILC under cygwin. Compiled and tested briefly
3487 without problems. More tests needed. The SIMs didn't compile
3490 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3492 * Fixed possible crash in silc_get_username in the
3493 lib/silcutil/silcutil.c.
3495 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3497 * Fixed a va_arg in silc/client_ops.c.
3499 * Oops, RC5 routines were named AES and caused some problems
3500 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3502 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3504 * Added new SilcIDIP structure into the lib/silccore/id.h and
3505 replaced the old `ip' fields from all SILC ID's to that type.
3506 This is a step towards IPv6 support.
3508 The silc_id_get_len takes now the ID as an extra argument.
3509 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3510 both IPv4 and IPv6 based ID's.
3512 The affected files are lib/silccore/id.[ch] and other files
3513 around the tree using these routines.
3515 * Removed the ID length arguments in server from various
3516 silc_server_send_notify_* routines -> they are not needed
3519 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3521 * Fixed memory leak in silc_encode_pem_file in the file
3522 lib/silcutil/silcutil.c.
3524 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3526 * Check minor version as well in the SKE. Affected files are
3527 silcd/protocol.c and lib/silcclient/protocol.c.
3529 * Added --identifier option to the server so that an identifier
3530 can be when creating the public key for the server. Affected
3531 file is silcd/silcd.c.
3533 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3534 lib/silccrypt/silcpkcs.c.
3536 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3538 * Register default ciphers and stuff when using -C option with
3539 the server. Affected file sildc/silcd.c.
3541 * Put back the servers public key filename format, it is better
3542 than the new one. For now, the client keys are saved with the
3543 new filename format. The affected file silc/client_ops.c.
3545 * Implemented the Cipher API for the rest of the ciphers that
3546 did not implement it or implemented it the wrong way.
3548 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3550 * Register default ciphers and stuff when using the -S option
3551 in the client. Affected file silc/silc.c. Same also when
3552 creating new key pair with -C option.
3554 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3556 * Fixed the silc_verify_public_key client operation function to
3557 save the public keys differently. The fingerprint is now
3558 used as filename and not the hostname. This way also the
3559 client keys are saved uniquely and not with hostnames. The
3560 affected file is silc/client_ops.c.
3562 * Trimmed the silc_hash_fingerprint function to remove extra
3563 whitespaces from the end of the fingerprint. The affected
3564 file is lib/silccrypt/silchash.c.
3568 * Added silc_cipher_register_default function to register all
3569 default ciphers. It can be used when configuration files
3570 does not exist and the application does not want any specific
3571 ciphers in any specific order.
3573 The SilcDList is now used as silc_cipher_list dynamically
3574 allocated cipher list. Removed the static list all together
3575 and now all ciphers must be allocated to the dynamic list.
3576 The silc_cipher_alloc routine was changed to check only the
3579 All silc_cipher_* routines that used to return int returns
3582 The affected files lib/silccrypt/silccrypt.[ch].
3584 * The same thing was done to silc_hash_* as for silc_cipher_*
3585 routines. Affected files lib/silccrypt/silchash.[ch].
3587 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3588 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3589 Added also silc_pkcs_[un]register[_default] functions.
3590 Removed the data_context from the PKCS API.
3592 * Added silc_hmac_register_default function to register default
3593 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3594 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3595 to unregister all hmacs at once.
3597 * Register the default ciphers, hash functions, PKCSs and HMACs
3598 if client's configuration file does not exist. The affected
3601 * The client did not load the hash functions from the SIM
3602 modules at all. Added support for this. Affected file is
3603 silc/clientconfig.c.
3605 * When decoding public key with silc_pkcs_public_key_decode, check
3606 the supported algorithm only if PKCS are registered. Affected
3607 file lib/silccrypt/silcpkcs.c. The same was done with the
3608 silc_pkcs_private_key_decode.
3610 * Fixed the SILC List routines to keep the list always in order.
3611 It used to change the list's order when traversing the list but
3612 not it preserves the order. Affected file lib/trq/silclist.h.
3614 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3616 * Added the client library to use the SilcSocketConnection's
3617 reference counter (by silc_socket_dup) to prevent the bug that
3618 the socket object may be freed underneath async operation.
3620 * The name resolv library checking fixes in the configure.in.pre.
3623 * Created new version of the protocol drafts for future
3624 development. The -03 drafts are the ones that will be changed
3625 in the trunk now and the -02 will remain as they are.
3627 * Send list of CUMODE notifys to the router when announcing
3628 the channel users to the router. Affected file silcd/server.c.
3629 If the router receiving channel founder CUMODE for a channel
3630 that already has channel founder it will send CUMODE notify
3631 to the sender to remove the channel founder rights from the
3632 announced client. Affected file silcd/packet_receive.c.
3634 * The CUMODE notify may now use Server ID as well as the entity
3635 who changes the mode. Updated protocool specs.
3637 * Updated INSTALL and README files.
3639 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3641 * New web pages in the http://silc.pspt.fi. The pages was
3646 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * Implemented the [DenyConnectin] config section in the server.
3649 Added silc_server_config_denied_conn to check whether incoming
3650 connection is denied. Affected file silcd/serverconfig.[ch].
3652 * Do not check the ports when checking the incoming configuration
3653 data if the port is 0, meaning any. Affected file is
3654 silcd/serverconfig.c.
3656 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3658 * Fixed buffer overflow in silc_string_compare in the file
3659 lib/silcutil/silcutil.c.
3661 * Fixed double free in silc_server_command_leave in the file
3664 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3666 * Fixed the version checking in the server. Affected file is
3669 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3671 * Fixed the configuration data fetching when accepting new
3672 connections in the server. Affected file silcd/server.c.
3674 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3676 * Added `sender_entry' argument to the function
3677 silc_server_packet_relay_to_channel so that we can check
3678 whether some destination actually belongs to the same route
3679 the sender belongs (ie, we must not resend the packet to the
3680 sender). Affected file silcd/packet_send.[ch].
3682 * Added `servername' field to the SilcClientEntry in the server
3683 to hold the name of the server where client is from. Affected
3684 file is silcd/idlist.h.
3686 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3688 * Moved the channel message encrypting in the router betwen
3689 router connections from silc_server_channel_message to the
3690 silc_server_packet_relay_to_channel since we want to check
3691 whether we have anybody channel before encrypting anything.
3692 Affected files silcd/packet_[receive/send].c.
3694 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3696 * Fixed the [AdminConnection] server config section to support
3697 multiple entries. Affected file silcd/serverconfig.c.
3699 * Added support into the server to check the validity of the
3700 incoming connection before executing any KE or authentication
3703 * The connection configuration is now saved to the KE and
3704 connection auth protocol contexts and not fetched anymore in
3705 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3707 * The local hosts listenning address and port is also resolved
3708 now when starting the server. We want to have the socket object
3709 to include the real address and port for the listener. Added
3710 new function silc_net_check_local_by_sock into the files
3711 lib/silcutil/silcnet.[ch].
3713 * Fixed a broadcast bug in server -> do not broadcast if we
3716 * Fixed a routing bug. Do not route broadcast packets ever.
3717 Broadcast packets must be processed always and not routed since
3718 they may be destined to some other host than yourself and thus
3719 would get routed without no good reason. Affected file is
3722 * Added function silc_server_config_is_primary_route to check
3723 whether primary router connection has been configured (a router
3724 configuration that we are initiating). If there is not, we
3725 will assume that there is only two routers in the SILC network
3726 and we will use the incoming router connection as our primary
3727 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3729 * Changed the order of the broadcasting. Broadcast _after_ the
3730 packet has been processed not before. Affected file is
3733 * Fixed a [ClientConnection] parsing bug. The port was never
3734 parsed correctly thus resulting to port 0. Affected file
3735 silcd/serverconfig.c.
3737 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3738 argument and did not set the broadcast packet flag. Affected
3739 file silcd/packet_send.c. Fixed same bug in the function
3740 silc_server_send_notify as well.
3742 * If we receive NEW_ID packet for our own ID in the server, ignore
3745 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3749 * Removed the nickname from the Private Message Payload.
3750 Updated the code and the protocol specs.
3752 * Updated protocol specs for submitting to the IETF.
3754 * Tweaked the Random Number Generator a bit. Affected file
3755 lib/silccrypt/silcrng.c. Exported a new function
3756 silc_rng_[global]_add_noise which can be used to add more
3759 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3761 * Do not parse packets with different timeout when protocol
3762 is active -> may cause problem with rekey. Affected file
3765 * When server receives signoff notify it must not create
3766 new channel key if the client is on any channels since the
3767 sender of the signoff notify will create it.
3769 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3771 * Added printing of error messages during SKE protocol from the
3772 failure packet sent by server during SKE. Affected file
3775 * Removed the client's failure_callback handling with timeout
3776 and handle it immediately when received.
3778 * The SKE library returned wrong type in SUCCESS and FAILURE
3779 packets. They must be 32 bit MSB not 16 bit MSB.
3781 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3783 * Ok, rewrote the logic of the re-key and now it seems to work.
3784 I tested it on high traffic with frequent re-keys without
3785 problems. Added hmac_receive (and renamed hmac to hmac_send)
3786 in SilcClientConnection in lib/silcclient/client.h and
3787 in SilcIDListData in silcd/idlist.h. Also, removed the
3788 SilcPacketParserContext's cipher and hmac fields as they are
3789 not needed anymore and actually caused some problems when
3790 the ciphers and hmac's changed underneath the packet parser.
3792 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3794 * If re-key protocol is active then process the incoming packets
3795 synchronously since we must assure that icoming packets encrypted
3796 with the old key is processed before the new keys is set to
3797 use. This is true other packets than for REKEY packets.
3798 Affected file silcd/server.c. The same was done to client library
3799 as well, affected file lib/silcclient/client.c.
3801 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3803 * Fixed bug in client and server to accept the force send if
3804 the packet is send from silc_[server/client]_packet_process
3805 function. Otherwise the packets are never delivered, oops.
3807 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Disable force sending of packets when REKEY protocol is active.
3810 We must assure that no packet is sent directly when rekey is
3811 performed. All packets must be sent through packet queue.
3812 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3813 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3814 function is silc_[server/client]_packet_send_real to check
3817 * Replaced the SIM paths from example config files to
3818 /usr/local/modules. Also, make install creates now
3819 /usr/local/silc/logs directory to hold all the SILC server
3822 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3824 * Made the configure.in.pre work on Solaris. Patch by salo.
3826 * Made all ciphers compatible with non-x86 machines. Defined
3827 CBC mode macros into lib/silccrypt/ciphers_def.h.
3829 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3831 * Fixed the make install.
3833 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3835 * When MAC computation fails the silc_packet_decrypt returned 0
3836 even though it was supposed to return -1. Fixed this. The
3837 affected file is lib/silccore/silcpacket.c.
3839 * Do not replace the config files in /etc/silc (in make install)
3840 if they already exist. Affected file ./Makefile.am.
3842 * Do not send re-key packets immediately but through packet queue.
3843 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3845 * Changed silc_net_check_host_by_sock to return FALSE if the
3846 IP/DNS could not be resolved. Though, it returns the IP address
3847 now even if it could not resolve it (but returns also FALSE).
3848 Affected file lib/silcutil/silcnet.[ch].
3850 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3852 * Added silc_pkcs_decode_identifier to decode the public key's
3853 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3854 Added also silc_pkcs_free_identifier. Added also new context
3855 SilcPublicKeyIdentifier.
3857 * Added -S option to the silc client. It is used to dump the
3858 contents of the specified public key file.
3860 * Changed the PKCS api to return the public key length when
3861 setting the public key.
3863 * Fixed a fatal bug in the public and private key file loading.
3864 Affected file lib/silccrypt/silcpkcs.c.
3866 * Execute the packet parsing for client with zero (0) timeout
3867 if the protocol is active. Affected file silcd/server.c.
3869 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * Made the key generation options to the silcd program. Added
3872 -C option, equivalent to client's option.
3874 * Added new [ServerKeys] config section to the server. It
3875 configures the server's public and private key.
3877 * Defined generic Public Key Payload into the protocol
3878 specification to send specific type of public keys and
3881 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3882 public key or certificate.
3884 * Implemented the GETKEY command to the server and to the
3885 client library and on user interface.
3887 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3889 * Made preliminary `make install' work.
3891 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Added SilcServerRekey context into silcd/idlist.h.
3895 * Added the PFS support as defined in the specification to the
3896 SKE protocol. Affected files lib/silcske/*.c.
3898 * Added `ske_group' field to the SilcServerRekey context to hold
3899 the number of the SKE group that is used with PFS in re-key.
3900 Affected file silcd/idlist.h.
3902 * Added PFS re-key support to the server. Affected file is
3905 * Added silc_protocol_cancel to cancel execution of the next
3906 state of the protocol. Affected file is
3907 lib/silccore/silcprotocol.[ch].
3909 * Added the re-key support with and without PFS to the client
3910 library. Re-key is performed once in an hour, by default.
3912 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3913 Added silc_client_rekey_callback and silc_client_rekey_final.
3914 Affected files are lib/silcclient/protocol.[ch] and
3915 lib/silcclient/client.[ch].
3917 * Removed the `hmac_key' and `hmac_key_len' fields from the
3918 SilcClientConnection structure; not needed. Affected file is
3919 lib/silcclient/client.h.
3923 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3925 * Do not ask whether user wants to use the negotiated private key
3926 for private messages, just use it. Affected file is
3927 silc/local_command.c.
3929 * Added `send_enc_key' and `enc_key_len' fields to the
3930 SilcIDListData structure since they are needed in the re-key
3931 phase. Affected file is silcd/idlist.[ch].
3933 * Implemented the simple re-key protocol into the server.
3934 Affected files silcd/server.c and silcd/protocol.[ch]. The
3935 re-key will be performed once in an hour, by default.
3937 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3938 Added silc_server_rekey, silc_server_rekey_callback and
3939 silc_server_rekey_final.
3941 * Removed Tunneled flag from the protocol. Updated the code
3942 and the specifications.
3944 * Adde `pfs' field to the SilcIDListData to indicate whether
3945 the PFS is to be performed in the re-key. Affected file is
3948 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3950 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3951 int64 of at least the xintXX size. If void * is less that 4
3952 bytes uint32 * will be used. Defined bool as boolean.
3954 * Changed _ALL_ unsigned long and unsigned int to uint32,
3955 unsgined short to uint16 in the source tree.
3957 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3958 not handle clients that has entry->data.registered == FALSE.
3959 They are not in the network anymore. Affected file is
3962 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3964 * Implemented the sending of the SERVER_SIGNOFF notify in the
3965 server. Affected file is silcd/server.c.
3967 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3968 Added also silc_notify_payload_encode_args into the
3969 lib/silccore/silcnotify.[ch].
3971 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3972 Affected file silcd/packet_receive.c.
3974 * Implemented the SERVER_SIGNOFF notify handling in the client
3975 library. Affected file lib/silcclient/client_notify.c. Also,
3976 implemnted the printing of the SERVER_SIGNOFF info to the
3977 application. Affected file silc/client_ops.c.
3979 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3980 if the deleting was successful. Affected file silcd/idlist.[ch].
3982 * Added support for public key authentication in the connection
3983 authentication protocol in the client library. Affected file
3984 lib/silcclient/protocol.c.
3986 * Changed the server's silc_idlist_get_clients_by_* interface
3987 to support already allocated array so that new entries may be
3988 added to pre-allocated array. Affected file silcd/idlist.[ch].
3989 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3990 and command replies.
3992 * All command reply functions in the server now calls the
3993 pending command callback even if error occured. This way the
3994 error will be delivered to the client as well. Affected files
3995 silcd/command.c and silcd/command_reply.c.
3997 * Fixed INFO command to return local server's info if no server
3998 was provided. Affected file lib/silcclient/command.c.
4000 * Removed RESTART command for good. Updated the code and the
4003 * Rewrote parts of the task system. It is a bit simpler now.
4004 Removed unsued task priorities. The affected files are
4005 lib/silcutil/silctask.[ch].
4007 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4009 * Moved the USERS printing from the library to the application.
4010 Affected files lib/silcclient/command.c and silc/client_ops.c.
4012 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4016 * Added channel key re-key support. The re-key is perfomed
4017 only by the router and is done once in an hour. Added `rekey'
4018 field to the SilcChannelEntry in the server. Affected files
4019 silcd/server.c and silcd/idlist.h.
4021 * Added silc_task_unregister_by_context into the file
4022 lib/silcutil/silctask.[ch].
4024 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4026 * Added SILC_UMODE_GONE mode to indicate when the client is not
4027 present in the SILC network. Added also support to the local
4028 command AWAY that will set this mode. Added support of showing
4029 "xxx is gone" in WHOIS command. The USERS command shows the
4030 gone status as well.
4032 * Fixed setting server and router operator privileges in the
4033 server's UMODE command. Affected file silcd/command.c.
4035 * Merged the SKE KE1 and KE2 payloads into one payload. The
4036 new KE payload is equivalent to the old KE2 payload.
4038 Cleaned up the SKE Start Payload parsing. It now uses the
4039 simple buffer unformatting to do the parsing. A lot faster
4042 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4043 to the SKE that is used to indicate whether both of the SKE
4044 parties should perform authentication. By default only the
4045 responder performs authentication. By setting this flag also
4046 the initiator must do authentication. By default it is unset
4047 since in normal SKE case, client to server connection, only
4048 the responder should do authentication. When doing SKE between
4049 two clients both should perform authentication. Updated the
4050 code and the protocol specs.
4052 * A little fix to IDENTIFY command in the server. Search the
4053 client first by hash not nickname. Affected file is
4056 * Fixed the silc_client_close_connection to support closing
4057 the client to client connections wihtout deleting too much
4058 data. Affected file lib/silcclient/client.c.
4060 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4061 are received if protocol used to be active but is not anymore
4062 the application would crash due to NULL pointer dereference.
4063 Affected files silcd/server.c and lib/silcclient/client.c.
4065 * Added `hash' field to the SilcClientConnection to include
4066 the hash function negotiated in the SKE protocol.
4068 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4069 to set the channel founder authentication data. A client can
4070 claim the founder rights later by providing the authentication
4071 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4072 This way the channel founder can regain the channel founder
4073 privileges even it is left the channel. This works only on
4074 local server and the client must be connected to the same
4075 server to be able to regain the founder rights. Updated the
4076 protocol specs accordingly.
4078 Added support to the CMODE command in the client to set the
4079 founder auth data. Read the README to see how to set it.
4081 Added support to the CUMODE command to claim the founder
4082 rights. Read the README to see how to do it.
4084 Added support for the founder authentication to the Channel
4085 Entry in the server. Affected file silcd/idlist.h.
4087 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4088 server's CMODE command. Affected file silcd/command.c.
4090 * Added the following new functions into lib/silccore/silcauth.[ch]:
4091 silc_auth_get_method and silc_auth_get_data.
4093 * The server now saves the remote hosts public key to the
4094 SilcIDListData pointer. Affected file silcd/protocol.c.
4096 * The normal server now does not remove the channel entry from
4097 the cache if the founder authentication data is set. It used
4098 to remove it if the founder was the last one on the channel on
4099 the server and left the channel. The auth data is saved and
4100 if the channel is re-joined later the old entry is used with
4101 the old auth data. Affected files silcd/command_reply.c and
4104 * Removed the `pkcs' field from the SilcIDListData structure
4105 in the server; it is not used. Affected file silcd/idlist.h.
4107 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4109 * Fixed packet processing on slow links. Partial packets were
4110 never re-processed because the incoming data buffer was cleared
4111 by the application. Application must not directly clear the
4112 sock->inbuf, the packet processing routines handle it. Fixed
4113 this in client library and in server.
4115 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4117 * Fixed the WHOIS and IDENTIFY send reply function to really
4118 check whether to send list or just one entry. Affected file
4121 * Cleaned up the LEAVE command's channel key distribution. The
4122 affected file silcd/command.c.
4124 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4125 can enforce the channel mode as well. In that case the ID
4126 includes the ID of the server. The code now enforces the
4127 mode change if the router have different mode than the server.
4129 * The notify client operation with CMODE_CHANGE notify can now
4130 return NULL client_entry pointer if the CMODE was not changed
4131 by client. Application must check for this.
4133 * Added <Server ID> argument to INFO command to support server
4134 info fetching by Server ID.
4136 * Added silc_server_announce_get_channel_users to get assembled
4137 packets of channel users of the specified channel. Affected
4138 file silcd/server.[ch].
4140 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4141 was freed underneath the ID Cache.
4143 * Re-announce clients when the server received CHANNEL_CHANGE
4144 notify from the router. Affected file silcd/packet_send.c.
4146 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4148 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4149 crashed since it did not handle the fact that there is no cipher
4150 called "3" and didn't check the error condition. Now fixed.
4152 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4153 flag. It can be used to send message requests.
4155 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4157 * Implemented the RESTART command in the client.
4159 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4160 notice type messages. Added notice printing to the user
4163 * The channel keys are not re-generated if the channel's mode
4164 is PRIVKEY, ie private key on the channel exists. Affected
4165 files silcd/server.c and silcd/command.c.
4167 * Fixed a little bug in channel message delivery when channel
4168 private keys are set in the server. Affected file is
4169 silcd/packet_send.c.
4171 * Changed the setting on channel->on_channel = TRUE from the
4172 silc_client_save_channel_key to the JOIN command reply. The
4173 key payload is not received if the private channel key is set.
4174 Affected file lib/silcclient/command_reply.c and the
4175 lib/silcclient/client_channel.c.
4177 * When the CMODE_CHANGE notify is sent and the channel private
4178 key mode is removed the channel key must be re-generated in
4179 other cells as well. Added this support for the router in the
4180 silcd/packet_receive.c.
4182 * Added new local command NOTICE to send notice message on
4183 channel. Affected file silc/local_command.[ch].
4185 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4187 * Added new local command ME to the client. It is used to send
4188 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4189 some action. Affected file silc/local_command.[ch].
4191 * Changed channel_message and private_message client operations
4192 to deliver the message flags to the application. Added also
4193 the `flags' arguments to the silc_client_send_channel_message
4194 and silc_client_send_private_message functions. Affected file
4197 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Redefined the Private Message Payload to support private message
4200 keys and to support the new private message flags. Updated
4201 the protocol specs. Flags makes it possible to have for example
4202 CTCP style messages.
4204 * Added new type SilcPrivateMessagePayload and defined an API
4205 for it in the lib/silcclient/silcprivate.[ch].
4207 * Tested private message private keys successfully. Tested the
4208 private message key set, unset and list commands with the new
4211 * Redefined the Channel Message Payload to include the channel
4212 message flags (equal with private message flags) to support
4213 for example CTCP style messages.
4215 * Defined some of the message (for channel and private message)
4216 flags. Updated the protocol specs and added the flags to the
4217 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4219 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4221 * Added SilcKeyAgreementStatus type to the key agreement routines
4222 to indicate the current status and error if one occured.
4223 The status types are defined in the lib/silcclient/silcapi.h.
4225 * Added new local command KEY that is used to set and unset private
4226 keys for channels, set and unset private keys for private messages
4227 with remote clients and to send key agreement requests and
4228 negotiate the key agreement protocol with remote client. The
4229 key agreement is supported only to negotiate private message keys,
4230 it currently cannot be used to negotiate private keys for channels,
4231 as it is not convenient for that purpose.
4233 * Fixed a minor pending callback setting bug in the function
4234 silc_client_get_client_by_id_resolve, now the function works.
4235 Affected file lib/silcclient/idlist.c.
4237 * Added function silc_net_get_local_port to get local bound
4238 port by socket. Added to lib/silcutil/silcnet.[ch].
4240 * Added `sockets' and `sockets_count' fields to the SilcClient
4241 object. They hold the sockets of the listenning sockets in
4242 the client. Listenning sockets may be for example the key
4243 agreement server. Affected file lib/silcclient/client.[ch].
4244 Added functions the silc_client_add_socket and the
4245 silc_client_del_socket. They are exported to the application
4248 * Added ~./silc/clientkeys to support other client's public keys.
4250 * Renamed verify_server_key client operation to verify_public_key
4251 and added one argument to indicate the type of the connection
4252 (server, client etc.).
4254 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4256 * Added silc_server_connection_auth_request to handle the
4257 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4258 silcd/packet_receive.[ch].
4260 * Added silc_server_send_connection_auth_request into the
4261 silcd/packet_send.c to send the connection auth request packet.
4263 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4266 * Fixed the public key authentication in responder side in the
4267 server. The `auth_data' pointer includes the SilcPublicKey
4268 not the path to the public key. Affected file silcd/protocol.c.
4270 * Implemented the public key authentication in the initiator side
4271 in the server. Affected file silcd/protocol.c.
4273 * Removed the [RedirectClient] config section from the server
4274 configuration. Is not needed and I don't want to implement it.
4276 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4278 * Cleaned up the CMODE command in the server. It now works
4279 correctly and supports all the modes defined in the protocol.
4280 Affected file is silcd/command.c.
4282 * Added `hmac_name' field to the SilcChannelEntry in the server
4283 to hold the default HMAC of the channel. It can be set when
4284 creating the channel (with JOIN command). Affected files
4287 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4288 type to indicate the change of the current cipher and hmac
4289 on the channel. Client can safely ignore the <cipher> argument
4290 (if it chooses to do so) since the CHANNEL_KEY packet will
4291 force the channel key change anyway. The <hmac> argument is
4292 important since the client is responsible of setting the new
4293 HMAC and the hmac key into use.
4295 * Fixed the CMODE command in the client library as well.
4297 * Tested CMODE command in router environment successfully.
4299 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4301 * Show the version of the remote client (or server) when connecting
4302 to the server. It is logged to the log file. Affected file
4303 is silcd/protocol.c.
4305 * Fixed the KILLED notify handling in the client library. The
4306 client must be removed from all channels when receiving the
4309 Also, do not remove the client entry when giving the KILL
4310 command but when the KILLED notify is received.
4312 * Removed silc_idlist_find_client_by_nickname from the server.
4313 Not needed anymore. Affected files silcd/idlist.[ch].
4315 * Implemented the CHANNEL_CHANGE notify type handling to the
4316 server. Affected file silcd/server.c.
4320 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Added silc_server_send_notify_invite to send the INVITE
4323 notify between routers.
4325 * Implemented the INVITE command correctly to the server.
4327 * Implemented the INVITE notify type handling in the server.
4329 * Implemented the INVITE command to the client library and on the
4332 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4334 * Added function silc_server_get_client_resolve to find the
4335 client entry by ID from all ID lists and then resolve it
4336 (using WHOIS) if it cannot be found. Affected file is
4339 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * Implemented the BAN command to the client library.
4343 * The JOIN command in the server now checks the invite list
4346 * Changed the silc_command_reply_payload_encode_va and the
4347 silc_command_payload_encode_va to support that if argument is
4348 NULL it ignores and checks the next argument. Affected file
4349 lib/silccore/silccommand.c.
4351 * Added silc_server_send_notify_ban to send the BAN notify
4352 type between routers.
4354 * Chaned the silc_notify_payload_encode to support that if
4355 argument is NULL it ignores and checks the next argument.
4356 Affected file lib/silccore/silcnotify.c.
4358 * Tested ban lists in router environment successfully.
4360 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4362 * Implemented BAN command to the server, in silcd/command.[ch].
4364 * Removed the BAN and INVITE_LIST modes from the CMODE command
4367 * Added function silc_string_match to regex match two strings.
4368 Affected files lib/silcutil/silcutil.[ch].
4370 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4372 * Redefined parts of the SilcChannelEntry in the server to support
4373 the new ban and invite lists.
4375 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4377 * Redefined the INVITE command. The same command can be used to
4378 invite individuals to the channel but also to manage the invite
4379 list of the channel (to add to and remove from the invite list).
4380 Updated the protocol specs.
4382 * Added new command SILC_COMMAND_BAN that can be used to manage
4383 the ban list of the channel. Updated the protocol specs.
4385 * Removed the channel modes: the SILC_CMODE_BAN and the
4386 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4387 in the CMODE command. The equivalent features are now available
4388 using INVITE and BAN commands. Updated the protocol specs.
4390 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4391 in the network about change in the current ban list. The notify
4392 type is not used by the client.
4394 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4395 support the invite lists.
4397 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4399 * Added new function silc_string_regexify that converts string
4400 including wildcard characters into regex string that can
4401 be used by the GNU regex library. Added into the file
4402 lib/silcutil/silcutil.[ch].
4404 Added silc_string_regex_combine to combine to regex strings
4405 into one so that they can be used as one regex string by
4406 the GNU regex library. Added into the file
4407 lib/silcutil/silcutil.[ch].
4409 Added silc_string_regex_match to match two strings. It returns
4410 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4412 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4414 * Imported GNU regex to the soruce tree into lib/contrib.
4415 Fixed some compiler warning from the regex.c.
4417 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4419 * Fixed MOTD command in the server to work in router environment.
4421 * Fixed the MOTD command in the client library to support
4422 the server argument in the command.
4424 * Added `nickname_len' argument to the silc_idlist_add_client
4425 in the server, as the `nickname' argument may be binary data
4428 * Added silc_idlist_get_channels to return all channels from
4431 * Implemented LIST command to the server. Affected file is
4434 * Implemented the LIST command to the client library and on the
4437 * Added [<user count>] argument to the LIST command reply.
4438 With private channels the user count is not shown.
4440 * Updated TODO and README.
4442 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4444 * The client entry's data.registered must be TRUE even with
4445 global client entry on global client list. The data.registered
4446 is used to check whether the client is anymore in the network,
4447 for example with WHOWAS command so it must be valid.
4449 * Fixed the WHOWAS command in the server. It now actually works
4450 in router environment. Added function into silcd/command_reply.c
4451 silc_server_command_reply_whowas_save.
4453 * Added silc_idlist_purge function to the silcd/idlist.c
4454 to periodically purge the ID Cache.
4456 * Fixed INFO command in the server. It works now in router
4457 environment. Added <server name> argument to the INFO command
4458 reply. Updated the protocol specs.
4460 * Fixed minor bug in silc_idcache_purge to not purge if the
4461 expire value is zero.
4463 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4464 they were buggy because of the WHOWAS information.
4466 * Fixed local command MSG to handle the async resolving of
4467 the remote client properly. It used to fail the first MSG.
4468 Affected file silc/local_command.c.
4470 * Added `data_len' field to SilcIDCache context.
4472 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4474 * Update TODO. Todo in commands in the server.
4476 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4479 used by routers as broadcast packet to inform other routers
4480 about the changed user mode.
4482 Implemented the notify handling in the server. Affected file is
4483 silcd/packet_receive.c. Added the function
4484 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4486 * Added new generic Channel Payload and deprecated the New Channel
4487 Payload. The New Channel Payload is now the generic Channel
4490 * Added new argument `mode' to the silc_server_send_new_channel
4491 as it is required in the Channel Payload now.
4493 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4494 and created a new and real SilChannelPayload to represent the
4495 new generic Channel Payload. Implemented the encode/decode
4496 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4498 * Added silc_server_get_client_channel_list to return the list
4499 of channels the client has joined for WHOIS command reply.
4500 Affected file silcd/server.[ch].
4502 * Implemented the channel list sending in the WHOIS command reply
4503 in server and in the client.
4505 Implemented the channel list displaying on the user interface
4506 as well. Affected file silc/client_ops.c.
4508 * Added silc_channel_payload_parse_list to parse list of Channel
4509 Payloads. It returns SilcDList list of SilcChannelPayloads.
4510 Client for example can use this function to parse the list of
4511 channels it receives in the WHOIS command reply. The caller
4512 must free the list by calling silc_channel_payload_list_free.
4513 Affected files lib/silccore/silcchannel.[ch].
4515 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * Added one new argument <user mode> to the WHOIS command reply
4518 to return the mode of the user in SILC. Updated the protocol
4521 Implemented it to the server and client.
4523 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4525 * Fixed the mode printing on the user interface on joining.
4526 Affected file silc/client_ops.c.
4528 * Implemented the UMODE command and user modes in general to the
4529 client library and to the user interface.
4531 * Implemented the UMODE command to the server.
4533 * The server now sends UNKNOWN_COMMAND error status if client sends
4534 unknown command. Affected file silcd/command.c.
4536 * All server commands now handle the command identifier the right
4537 way when sending the command reply to the client. The client can
4538 use to identify the command replies with the identifier.
4540 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4542 * Added silc_server_get_client_route to resolve the route to
4543 the client indicated by the client ID. Affected file is
4546 * Added silc_server_relay_packet as general function to relay
4547 packet to arbitrary destination. This deprecates functions
4548 like _send_private_message_key, _relay_notify etc. Affected
4549 file is silcd/packet_send.[ch].
4551 Removed silc_server_send_key_agreement,
4552 silc_server_send_private_message_key and
4553 silc_server_packet_relay_notify functions from the file
4554 silcd/packet_send.[ch].
4558 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4559 server. Affected file silcd/packet_receive.[ch].
4561 * Implemented the KILL command to the client. Implemented the
4562 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4563 Affected files lib/silcclient/command[_reply].c and
4564 lib/silcclient/client_notify.c. Implemented the KILL notify
4565 printing in the user inteface.
4567 * Fixed a lot silc_parse_nick memory leaks from the client
4568 library in the file lib/silcclient/command.c.
4570 * Changed the silc_server_send_notify_on_channels's `sender'
4571 argument from SilcSocketConnection to SilcClientEntry to
4572 check the sender as entry and not as connection object and not
4573 to send to the client provided as argument. The affected file
4574 is silcd/packet_send.[ch].
4576 * The notify packets that are destined directly to the client used
4577 to not to be processed by the server. Now changed that and the
4578 server processes all notify packets. After relaying the packet
4579 to the client the notify packet is processed in the server.
4581 * The silc_server_free_client_data now checks whether there is
4582 pending outgoing traffic for the client and purges the data to
4583 the network before removing the client entry.
4585 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4587 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4588 an client is killed from the SILC Network. Updated the protocol
4591 Added new function silc_server_send_notify_killed to the
4592 silcd/packet_send.[ch].
4594 * Added function silc_server_packet_relay_notify to relay notify
4595 packets that are destined directly to a client. In this case
4596 the server does not process the notify packets but merely relays
4597 it to the client. Affected file silcd/packet_send.[ch].
4599 Added also silc_server_packet_process_relay_notify to check
4600 whereto relay the notify. Affected file is
4601 silcd/packet_receive.[ch].
4603 * Implemented the KILL command to the server.
4607 * Added the backup schema desgined last fall to the protocol
4608 specs for everyone to see. The specification is in the
4609 *-spec-xx.txt draft and the packet type definitions for the
4610 backup routers is in *-pp-xx.txt draft. Thusly, added also
4611 new packet type SILC_PACKET_CELL_ROUTERS.
4613 * A big security problem in the implementation discovered. The
4614 signoff of an client did not cause new channel key generation
4615 which it of course should've done. The channel keys must be
4616 always re-generated when client leaves (or signoffs) the channel.
4617 The silc_server_remove_from_channels funtion now handles
4618 the channel key re-generation.
4620 * Added `sender' argument to the silc_server_send_notify_on_channels
4621 to not to send the client provided as argument. Affected file
4622 silcd/packet_send.[ch].
4624 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4626 * Implemented OPER and SILCOPER commands into the server and
4629 * Added silc_auth_verify and silc_auth_verify_data to verify
4630 the authentication directly from the authentication payload.
4631 It supports verifying both passphrase and public key based
4632 authentication. Affected file lib/silccore/silcauth.[ch].
4634 * Added `hash' field to the SilcIDListData structure. It is the
4635 hash negotiated in the SKE protocol. Affected file is
4638 * Slight redesigning of the SilcAuthPayload handling routines.
4639 Do not send SilcPKCS but SilcPublicKey as argument.
4641 * Implemented the public key authentication support to the
4642 serverconfig. The public key is loaded from the provided path
4643 and saved as authentication data to void * pointer. Thus,
4644 changed the unsigned char *auth_data to void *auth_data;
4646 * Fixed SHUTDOWN command to send the reply before the server
4647 is shutdown. :) Affected file silcd/command.c.
4649 * Fixed fatal bug in CONNECT command. The hostname was invalid
4650 memory and server crashed. Affected file silcd/command.c.
4652 * Fixed fatal bug in CLOSE command. The server_entry became
4653 invalid but was referenced later in the command. Affected file
4656 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4658 * Fixed fatal bug in failure packet handling. Server ignored
4659 the failure and thus crashed when it came.
4663 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4665 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4666 that the command may be executed only once in (about) 2 seconds.
4667 The old SILC_CF_LAG flag is same but allows command bursts up
4668 to five before limiting.
4670 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4671 server code. Various commands now includes the CF_LAG_STRICT
4672 flag to disallow any kind of miss-use of the command.
4674 * Fixed the silc_buffer_unformat to not to allocate any data
4675 if the length of the data is zero. It used to allocate the
4676 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4678 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4680 * Changed the format of AdminConnection configuration section
4681 in the server. Added username of the admin to the format.
4682 Affected files silcd/serverconfig.[ch].
4684 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4685 to return admin configuration data by host, username and/or
4688 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4690 * Implemented WHOWAS command to the server. Added the functions:
4692 silc_server_command_whowas_parse,
4693 silc_server_command_whowas_send_reply,
4694 silc_server_command_whowas_from_client and
4695 silc_server_command_whowas_from_server
4697 * Added <Client ID> argument to the WHOWAS command reply. Updated
4698 the protocol specs accordingly.
4700 * Implemented WHOWAS command and command_reply to the client
4703 Implemented the WHOWAS printing on the user interface.
4705 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4707 * Added new argument to the WHOWAS command reply, the real name.
4708 It is an optional argument. Updated the protocol specs.
4710 * Added SilcIDCacheDestructor callback that is registered when
4711 the SilcIDCache is allocated. The callback is called when
4712 an cache entry in the ID Cache expires, or is purged from the
4713 cache. Added into lib/silccore/idcache.[ch].
4715 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4716 to destruct the client entries when the cache entry expires.
4717 Other ID Cache's in server and in the client library ignores
4720 * If the ID Cache entry's `expire' field is zero then the entry
4721 never expires. Added boolean `expire' argument to the
4722 silc_idcache_add function in the lib/silccore/idcache.[ch].
4723 If it is TRUE the default expiry value is used.
4725 * Added silc_server_free_client_data_timeout that is registered
4726 when client disconnects. By default for 5 minutes we preserve
4727 the client entry for history - for WHOWAS command.
4729 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4731 * Added support to the server to enforce that commands are not
4732 executed more than once in 2 seconds. If server receives
4733 commands from client more frequently, timeout is registered
4734 to process the commands. Affected file silcd/command.c.
4735 Added new function silc_server_command_process_timeout.
4737 * Changed NICK_NOTIFY handling in client library to check that
4738 if the client's nickname was changed, so there is no need to
4739 resolve anything from the server.
4741 * Removed error printing from the WHOIS and IDENTIFY commands.
4742 If error occurs then it is ignored silently in the client library.
4743 The application, however, may map the received error to
4744 human readable error string. The application currently maps
4745 the NO_SUCH_NICKNAME error to string.
4747 * Made the command status message public to the application. Moved
4748 them from lib/silcclient/command_reply.c to
4749 lib/silcclient/command_reply.h. The application can map the
4750 received command status to the string with the
4751 silc_client_command_status_message function.
4753 * Added check to the server to check that client's ID is same
4754 as the Source ID in the packet the client sent. They must
4757 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4759 * Added dist-bzip hook to the Makefile.am to make bzip2
4760 compressed distributions.
4762 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4764 * Server now enforces the maximum length for the nickname and
4765 the channel as protocol specification dictates. 128 bytes for
4766 nickname and 256 bytes for channel name.
4768 * Moved the WHOIS printing to the application. The client libary
4769 does not print out the WHOIS information anymore, the application
4770 must do it. Renamed silc_client_command_reply_whois_print to
4771 the silc_client_command_reply_whois_save.
4773 The client's idle time is also sent to the application now, and
4774 the idle is shown on screen.
4776 * Added silc_client_command_reply_identify_save to save the
4777 received IDENTIFY entries.
4779 * Do not check for channel private keys in message sending and
4780 reception if the channel does not have the PRIVKEY mode set.
4781 Affected file lib/silclient/client_channel.c.
4783 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4785 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4786 just surfaced after chaning the JOIN procedure.
4788 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4790 * Added silc_client_get_clients_by_list to get client entries
4791 from Client ID list, that is returned for example by JOIN
4792 and USERS command replies. The application should use this
4793 function for example when JOIN command reply is received to
4794 resolve the clients already on the channel (library does not
4795 do that anymore as USERS command reply is not used in the JOIN
4796 procedure anymore). Affected files lib/silcclient/silcapi.h and
4797 lib/silcclient/idlist.c.
4799 * JOIN command reply and USERS command reply returns now SilcBuffer
4800 pointers instead of unsigned char pointers when returning
4801 the client list and mode list.
4803 * Added <Client ID> argument to the JOIN command reply, mainly
4804 for the server to identify for which client the command was
4805 originally sent. Updated protocol specs accordingly.
4807 * Added SilcDlist private_key pointer to the SilcChannelEntry
4808 in the client to support the channel private keys. Affected
4809 file is lib/silcclient/idlist.h.
4811 * Added SilcChannelPrivateKey argument to the function
4812 silc_client_send_channel_message so that application can choose
4813 to use specific private ke if it wants to. If it is not provided,
4814 the normal channel key is used, unless private keys are set.
4815 In this case the first (key that was added first) is used
4816 as the encryption key.
4818 * Implemented the support for channel private key handling.
4819 Implemented the following functions:
4821 silc_client_add_channel_private_key,
4822 silc_client_del_channel_private_keys,
4823 silc_client_del_channel_private_key,
4824 silc_client_list_channel_private_keys and
4825 silc_client_free_channel_private_keys
4827 Affected file lib/silcclient/client_channel.c.
4829 * Added the support for the private keys in the channel message
4830 sending and encryption and in the message reception and
4831 decryption. Affected funtions are
4832 silc_client_send_channel_message and silc_client_channel_message.
4834 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * Added SKE's key verify callback to the client library's
4837 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4839 * Removed the statement that server (or router) must send USERS
4840 command reply when joining to the channel so that the client
4841 knows who are on the channel. Instead, the client list and
4842 client's mode list is now sent in the JOIN command reply to the
4843 client who joined channel. This is better solution.
4845 * Added function silc_server_get_users_on_channel and function
4846 silc_server_save_users_on_channel to the silcd/server.[ch].
4848 * Removed function silc_server_command_send_users from the
4851 * Do not show topic on the client library anymore. The topic is
4852 sent in the command reply notify to the application and the
4853 application must show the topic now.
4855 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4857 * Added client searching by nickname hash into the IDENTIFY and
4858 WHOIS commands in the server as they were clearly missing from
4859 them. Affected file is silcd/command.c.
4861 * Fixed a bug in private message receiving in the client library.
4862 The remote ID was freed and it wasn't supposed, now it is
4865 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4867 * Minor fix to the channel payload; allocate the data area, as it
4868 needs to be of specific length.
4870 * If the key agreement port is zero then the operating
4871 system will define the bound port. Affected files are
4872 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4874 * Added new function silc_channel_payload_decrypt into the file
4875 lib/silccore/silcchannel.[ch].
4877 * Moved the channel message etc, check from silc_packet_decrypt
4878 to applications. The library calls now a generic
4879 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4880 when the packet is either normal or special. This was done to
4881 allow more wide range of checking that was not allowed when
4882 the code was in library. Now applications can do virtually any
4883 checks to the packet and return to the library the decision how
4884 the packet should be processed. Affected files are
4885 lib/silccore/silcpacket.[ch].
4887 Added silc_server_packet_decrypt_check to the server and
4888 silc_client_packet_decrypt_check to the client library.
4890 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4891 to send with specified source and destination information.
4893 * Channel message delivery between routers was broken after the
4894 channel key distribution was fixed earlier. The channel key
4895 was used be to distributed to other routers as well which is not
4896 allowed by the protocol. Now this is fixed and channel keys
4897 really are cell specific and the channel message delivery between
4898 routers comply with the protocol specification.
4900 * Fixed various commands in server to check also the global list
4901 for the channel entry and not just the local list. The affected
4902 file silcd/command.c.
4904 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4906 * Added assert()s to buffer formatting and unformatting routines
4907 to assert (if --enable-debug) when error occurs. Affected
4908 file: lib/silcutil/silcbuffmt.c.
4910 * Changed to auto-reconnect to check whether the remote host is
4911 router and register the re-connect timeout if it is. It used
4912 to check that whether we are normal server, but router must do
4913 auto-reconnect with another router as well. Affected file
4916 * Removed the [<key len>] option from CMODE command as the cipher
4917 name decides the key length, nowadays. See the defined ciphers
4918 from the protocol specification.
4920 * Added [<hmac>] option to the CMODE command to define the HMAC
4921 for the channel. Added SILC_CMODE_HMAC channel mode.
4923 * Added [<hmac>] option for the JOIN command so that user can
4924 select which HMAC is used to compute the MACs of the channel
4927 * Added Hmac field to the Channel Message Payload. The integrity
4928 of plaintext channel messages are now protected by computing
4929 MAC of the message and attaching the MAC to the payload. The
4930 MAC is encrypted. Now, it is clear that this causes some
4931 overhead to the size of the packet but rationale for this is that
4932 now the receiver can verify whether the channel message decrypted
4933 correctly and also when private keys are set for the channel the
4934 receiver can decrypt the packet with several keys and check from
4935 the MAC which key decrypted the message correctly.
4937 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4938 lib/silccrypt/silccipher.[ch].
4940 * Added silc_hash_len to return the digest length into the
4941 lib/silcrypt/silchash.[ch].
4943 * Rewrote parts of Silc Channel Payload interface in the
4944 lib/silccore/silcchannel.[ch]. The encode function now also
4945 encrypts the packet and parse function decrypts it.
4947 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Fixed a minor formatting bug in the SKE's key material processing.
4950 It actually might have processed the keys wrong way resulting
4953 * Redefined the mandatory HMAC algorithms and added new algorithms.
4954 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4955 and hmac-md5 truncated to 96 bits. The mandatory is now
4956 hmac-sha1-96. Rest are optional (including the one that used
4957 to be mandatory). Rationale for this is that the truncated HMAC
4958 length is sufficient from security point of view and can actually
4959 make the attack against the HMAC harder. Also, the truncated
4960 HMAC causes less overhead to the packets. See the RFC2104 for
4963 * Added new [hmac] configuration section. The SKE used to use
4964 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4965 is of course wrong. The official names that must be proposed in
4966 the SKE are the ones defined in the protocol specification
4967 (hmac-sha1-96 for example). The user can configure any hmac
4968 using any hash function configured in the [hash] section. At
4969 least, the mandatory must be configured.
4971 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4973 * Added HMAC list to the SKE proposal list. It has now both
4974 hash algorithm list and HMAC list. This makes the protocol
4975 incompatible with previous versions. The SKE now seems to work
4976 the way it is supposed to work, for the first time actually.
4978 * Defined plain Hash algorithms to the protocol specification.
4981 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4983 * Implemented support for key agreement packets into the server.
4984 Added functions silc_server_key_agreement and
4985 silc_server_send_key_agreement. Other than these functions,
4986 server has nothing to do with this packet.
4988 * Added support for private message key packets into the server.
4989 Added functions silc_server_private_message_key and
4990 silc_server_send_private_message_key.
4994 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4995 called in the protocol's final callback instead in the END
4996 protocol state. This makes a little more sense and in the same
4997 time in client we can use the same protocol routines for normal
4998 key exchange and to key agreement packet handling as well.
5000 * Added to both client's and server's KE protocol context the
5001 SilcSKEKeyMaterial pointer to save the key material. We will
5002 bring the key material to the protocol's final callback by doing
5003 this. The final callback must free the key material.
5005 * Added SKE's packet_send callback into client's KE protocol
5006 context so that the caller can choose what packet sending function
5007 is used. This way we can use different packet sending when
5008 doing normal SKE when doing key agreement packet handling (in
5009 the key agreement packet handling we do not want to encrypt
5012 * Implemented the responder side of the key agreement routines
5013 in the client. The client can now bind to specified port and
5014 accept incoming key negotiation. The key material is passed
5015 to the application after the protocol is over.
5017 * Implemented the processing of incoming Key Agreement packet
5018 in the client. Added function silc_client_key_agreement to
5021 * Implemented the intiator side of the key agreement routines
5022 in the client. The client can now initiate key agreement with
5023 another remote client. The key material is passed to the
5024 application after the protocol is over.
5026 * Created client_keyagr.c to include all the key agreement
5029 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5030 SILC_TASK_CALLBACK except that it is not static.
5032 * Created client_notify.c and moved the Notify packet handling
5033 from the client.[ch] into that file.
5035 * Created client_prvmsg.c and moved all private message and
5036 private message key routines from the client.[ch] into that file.
5038 * Create client_channel.c and moved all channel message and
5039 channel private key routines from the client.[ch] into that file.
5041 * Changed silc_client_get_client_by_id_resolve to resolve with
5042 WHOIS command instead of IDENTIFY command, in the file
5043 lib/silclient/idlist.c.
5045 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5047 * Implemented the SKE's responder side to the Client library.
5049 * When FAILURE is received to the protocol do not trust it
5050 blindly. Register a timeout to wait whether the remote closes
5051 the connection as it should do it, only after that process the
5052 actual failure. This was changed to both client and server.
5054 * Added client_internal.h to include some of the structures
5055 there instead of client.h in lib/silcclient/.
5057 * Added function silc_task_unregister_by_callback to unregister
5058 timeouts by the callback function.
5060 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Some "Incomplete WHOIS info" errors has been appearing on the
5063 log files. Took away the entry->userinfo check from WHOIS
5064 reply sending. The entry->userinfo is now " " if client did not
5065 provide one. I thought this was fixed earlier but something
5066 is wrong still. Let's see if the error still appears.
5068 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5070 * Fixed a minor bug in the login when the channel key is
5071 re-generated in the server. It used to generate the key in
5072 wrong order and thus caused problems in the channel traffic.
5074 * Fixed a minor bug in channel key distsribution after
5075 KICK command. The key was not sent to the router even though
5078 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5080 * Added silc_ske_process_key_material_data as generic routine
5081 to process any key material as the SILC protocol dictates. The
5082 function is used by the actual SKE library but can be used by
5083 applications as well. This relates to the private message keys
5084 and the channel private keys since they must be processed the
5085 same way the normal SILC session keys. The protocol dictates
5086 this. Affected files: lib/silcske/silcske.[ch].
5088 Added also silc_ske_free_key_material to free the
5089 SilcSKEKeyMaterial structure.
5091 * Defined silc_cipher_set_key function to set the key for
5092 cipher without using the object's method function. The affected
5093 files: lib/silccrypt/silccipher.[ch].
5095 * Implemented silc silc_client_add_private_message_key,
5096 silc_client_add_private_message_key_ske,
5097 silc_client_del_private_message_key,
5098 silc_client_list_private_message_keys and
5099 silc_client_free_private_message_keys functions in the
5102 Added functions silc_client_send_private_message_key to send
5103 the Private Message Key payload and silc_client_private_message_key
5104 to handle incoming Private Message Key payload.
5106 * Added Cipher field to the Private Message Key payload to set
5107 the cipher to be used. If ignored, the default cipher defined
5108 in the SILC protocol (aes-256-cbc) is used.
5110 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * Removed lib/silcclient/ops.h file.
5114 Redefined parts of the SILC Client Library API. Created new
5115 file silcapi.h that deprecates the ops.h file and defines the
5116 published Client Library API. Defined also private message key
5117 API and channel private key API into the file.
5119 This is the file that the application must include from the
5120 SILC Client Library. Other files need not be included by
5121 the application anymore.
5123 * Added new key_agreement client operation callback and also
5124 defined the Key Agreement library API for the application.
5126 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5129 is used by clients to request key negotiation between another
5130 client in the SILC network. If the negotiation is started it
5131 is performed using the SKE protocol. The result of the
5132 negotiation, the secret key material, can be used for example
5133 as private message key.
5135 Implemented the Key Agreement payload into the files
5136 lib/silccore/silauth.[ch].
5138 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5140 * Redefined ciphers for the SILC protocol. Added some new ciphers
5141 and defined the key lengths for the algorithms. Changed the
5142 code accordingly. The default key length is now 256 bits.
5144 * Fixed SKE key distribution function silc_ske_process_key_material
5145 when the key length is more than 128 bits. The default key
5146 length in SILC is now 256 bits.
5148 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5149 to indicate unsupported algorithm.
5151 * Renamed rijndael.c to aes.c and all functions as well.
5153 * Fixed a long standing channel key setting bug in client library.
5154 Weird that it has never surfaced before.
5156 * Fixed bug in channel deletion. If the entire channel is removed
5157 then it must also delete the references of the channel entry
5158 from the client's channel list as the client's channel entry and
5159 the channel's client entry share same memory.
5161 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * Implemented CONNECT and SHUTDOWN commands in the client.
5165 * Implemented CLOSE command to the client.
5167 * Added the function silc_idlist_find_server_by_name into the
5168 files silcd/idlist.[ch].
5170 Added the function silc_idlist_find_server_by_conn into the
5171 files silcd/idlist.[ch].
5173 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5175 * DIE command was renamed to SHUTDOWN. Updated the both code
5178 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5179 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5181 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5184 * Added function silc_server_create_connection function to create
5185 connection to remote router. My server implementation actually
5186 does not allow router to connect to normal server (it expects
5187 that normal server always initiates the connection to the router)
5188 so the CONNECT command is only good for connecting to another
5191 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5193 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5194 or some other client was kicked from the channel.
5196 Implemented the handling of the notify type to both client
5199 Implemented silc_server_send_notify_kicked to send the KICKED
5200 notify. It is used to send it to the server's primary router.
5202 * Implemented the KICK command into server and client.
5204 * Added `query' argument to the silc_idlist_get_client function
5205 to indicate whether to query the client from server or not if
5208 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5209 to indicate that the client is not channel founder.
5213 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5215 * Removed the rng context from SilcPacketContext structure and
5216 changed that the packet routine uses the Global RNG API.
5218 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * Added support for quit message that client can "leave" on the
5221 channel when it quits the SILC. It is ditributed inside the
5222 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5224 Added silc_server_free_client_data that will take the
5225 signoff message as argument.
5227 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5229 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5231 * Updated parts of the protocol specification to keep it up
5234 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5236 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5237 payloads in one packet.
5239 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5240 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5241 use now the new List flag.
5243 * Also deprecated the following packet types: REPLACE_ID,
5244 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5246 * Added list support for Notify packet in server.
5248 * Added silc_server_send_notify_channel_change to send the
5249 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5250 the silc_server_send_replace_id.
5252 * Added silc_server_send_notify_nick_change to send the
5253 NICK_CHANGE notify type. Deprecates the function
5254 silc_server_send_replace_id.
5256 * Added silc_server_send_notify_join to send the JOIN notify type.
5257 Deprecates the function silc_server_send_new_channel_user.
5259 * Added silc_server_send_notify_leave to send LEAVE notify type.
5260 Deprecates the function silc_server_send_remove_channel_user.
5262 * Added silc_server_send_notify_cmode and
5263 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5264 types. Deprecates the silc_server_send_set_mode function.
5266 * Added SERVER_SIGNOFF notify type to indicate that server has
5267 quit. This means that all clients on the channel from that
5268 server will drop. This can be also used when netsplit happens.
5270 Deprecated REMOVE_ID packet type since it is not needed anymore
5273 Added silc_server_send_notify_server_signoff to send the
5274 SERVER_SIGNOFF notify type. Deprecates the function
5275 silc_server_send_remove_id.
5277 Added also silc_server_send_notify_signoff to send the
5278 SIGNOFF notify type.
5280 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5281 SILC protocol from this day on. Changed the protocol
5282 specification as well.
5284 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5285 notify type. It is used between routers to notify about
5286 topic changes on a channel.
5288 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5291 * Partly updated the protocol specification to comply with the
5292 changes now made. It is still though a bit outdated.
5294 * The JOIN notify type now takes one extra argument <Channel ID>.
5295 The packet used to be destined to the channel but now the
5296 JOIN type may be sent as list thus it is impossible to
5297 destine it to any specific channel. By adding this argument
5298 it is again possible.
5300 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * Added CREDITS file. The CHANGES and CREDITS file will appear
5303 in the distribution as well.
5305 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5308 types in the server's silcd/packet_receive.c.
5310 * Implemented CMODE and CUMODE to work in router environment.
5312 * Fixed minor encoding and decoding buglet from the
5313 lib/silccore/silcmode.c.
5315 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5318 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5320 * Changed all SilcConfigServer* and silc_config_server* to
5321 SilcServerConfig* and silc_server_config*, respectively.
5324 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5326 * Associated the ID (client or server ID) to the Authentication
5327 Payload to avoid any possibility of forging. Updated the
5328 protocol specification and the code accordingly.
5330 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5332 * The RSA key length is now save to the RsaKey context in the
5333 key generation process in lib/silccrypt/rsa.c. The key length
5334 is now used to figure out the maximum size of the block allowed
5335 to be encrypted/signed.
5337 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5338 is equivalent to the silc_mp_mp2bin but does not allocate any
5341 * Changed silc_mp_mp2bin API to take length argument. If it is
5342 non-zero then the buffer is allocated that large. If zero, then
5343 the size is approximated using silc_mp_sizeinbase, which however
5346 * Created Global RNG API which is global RNG that application can
5347 initialize. After initializing, any routine anywhere in the
5348 code (including library) can use RNG without allocating a new
5349 RNG object. This was done to allow this sort of use of the
5350 RNG in code that has no chance to allocate RNG object. All
5351 applications currently allocate this and many routines in the
5352 library use this. Affected file lib/silccrypt/silcrng.[ch].
5354 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5355 it to use the Global RNG API.
5357 * Defined Authentication Payload into protocol specification that
5358 is used during SILC session to authenticate entities. It is
5359 used for example by client to authenticate itself to the server
5360 to obtain server operator privileges.
5362 Implemented this payload into the lib/silccore/silcauth.[ch].
5363 Implemented also routines for public key based authentication
5364 as the new protocol specification dictates.
5366 Moved definitions of different authentication methods from
5367 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5369 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5370 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5371 silc_pkcs_verify_with_hash functions into the file
5372 lib/silccrypt/silcpkcs.[ch].
5374 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5376 * The client entry's userinfo pointer must be always valid.
5377 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5378 will fail since it requires the userinfo. Now, the userinfo
5379 is allocated as "" if actual userinfo does not exist. Actually,
5380 it must exist and it is totally Ok to drop client connections
5381 that does not announce the userinfo. However, we will make
5382 this workaround for now.
5384 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5385 to return the remote port by socket.
5387 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5389 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5390 SILC_SERVER_PENDING_EXEC and added an new macro
5391 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5392 data or when error occurs while processing the pending command.
5394 Added new argument `destructor' into silc_server_command_pending
5395 and to the SilcServerCommandPending object. This destructor is
5396 now called after calling the pending callback or if error occurs
5397 immediately. If error occurs the actual pending callback won't
5398 be called at all - only the destructor. The destructor may be
5399 NULL if destructor is not needed.
5401 All this applies for client library code as well. Similar
5402 changes were made there as well for the pending commands.
5404 In the client, the application must now allocate the
5405 SilcClientCommandContext with the silc_client_command_alloc
5408 * Added reference counter to the SilcServerCommandContext. Added
5409 function silc_server_command_alloc and silc_server_command_dup
5412 Same type of functions added to the client library for the same
5415 * Removed the cmd_ident from IDListData away since it is now
5416 global for all connections. It is the command identifier used
5417 in command sending and with pending commands. The affected file
5420 * Added reference counter to the SilcSocketConnection objecet to
5421 indicate the usage count of the object. The object won't be
5422 freed untill the reference counter hits zero. Currently only
5423 server uses this, and client ignores it. The client must be
5424 set to use this too later. The affected files are
5425 lib/silccore/silcsockconn.[ch]. Added also the function
5426 silc_socket_dup to increase the reference counter.
5428 This was mainly added because it is possible that the socket
5429 is removed underneath of pending command or other async
5430 operation. Now it won't be free'd and proper DISCONNECTING
5431 flags, etc. can be set to avoid sending data to connection that
5432 is not valid anymore.
5434 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5435 the connection. After that it sets SILC_SET_DISCONNECTED.
5436 It is, however, possible that the socket data is not still freed.
5437 The silc_server_packet_process now checks that data is not
5438 read or written to connection that is DISCONNECTED. The socket
5439 get's freed when the reference counter hits zero.
5441 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5443 * Changed the client operation API: channel_message operation's
5444 `sender' is now the client entry of the sender, not the nickname
5445 and the `channel' is the channel entry, not the channel name.
5447 In the private_message operation the `sender' is now also the
5448 client entry of the sender not the nickname.
5450 Affected file is lib/silcclient/ops.h and all applications
5451 using the client operations.
5453 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5455 * Moved the calling of ops->connect() from connect_to_server_final
5456 into receive_new_id functin since that is the point when the
5457 client is actually allowed to send traffic to network. The
5458 affected file is lib/silcclient/client.c.
5460 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5462 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5463 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5464 (if needs broadcasting) instead of broadcasting the packets one
5465 by one which would make a burst in the network traffic.
5467 * Added `broadcast' argument to the functions in silcd/server.[ch]
5468 silc_server_create_new_channel[_with_id] to indicate whether
5469 to send New Channel packet to primary router.
5471 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5473 * Added new function into the silcd/server.[ch] files:
5474 silc_server_create_new_channel_with_id to create new channel with
5475 already existing Channel ID.
5477 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5478 lib/silccore/silcpacket.h. This packet is used t send list of
5479 Set Mode payloads inside one packet. Server uses this to set
5480 the modes for the channels and clients on those channels, that it
5481 announced to the router when it connected to it. The protocol
5482 specification has been updated accordingly.
5484 * The silc_server_new_channel did not handle the packet coming
5485 from normal server as it normally does not send that. However,
5486 when it announces its channels it does send it. Implemented
5487 the support for that.
5489 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5490 into the file lib/silccore/id.h.
5492 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5494 * Fixed memory leaks in the functions silc_idlist_del_client,
5495 silc_idlist_del_channel and silc_idlist_del_server in the file
5496 silcd/idlist.c. All of those leaked like a sieve.
5498 * Fixed some small memory leaks in the client's function
5499 silc_client_notify_by_server.
5501 * Added functions into silcd/server.c: silc_server_announce_clients,
5502 silc_server_announce_channels and silc_server_announce_server.
5503 These functions are used by normal and router server to announce
5504 to its primary router about clients, channels and servers (when
5505 router) that we own. This is done after we've connected to the
5508 These functions effectively implements the following packet types:
5509 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5510 and SILC_PACKET_NEW_ID_LIST.
5512 * Added new functions into the silcd/packet_receive.[ch]:
5513 silc_server_new_id_list, silc_server_new_channel_list and
5514 silc_server_new_channel_user_list to handle the incoming
5515 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5517 * Added support of changing Channel ID in the function
5518 silc_server_replace_id. If the server that announces a channel
5519 to the router already exists in the router (with same name but
5520 with different Channel ID), router is responsible to send
5521 Replace ID packet to the server and force the server to change
5522 the Channel ID to the one router has.
5524 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5525 client that the Channel ID has been changed by the router. The
5526 normal server sends this to the client. Client must start using
5527 the new Channel ID as the channel's ID.
5529 Implemented handling of this new type into lib/silcclient/client.c
5530 into the function silc_client_notify_by_server.
5532 * Added new function silc_idlist_replace_channel_id into the files
5533 silcd/idlist.[ch] to replace the Channel ID.
5535 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5537 * Call silc_server_command_identify_check always when processing
5538 the IDENTIFY command in silcd/command.c
5540 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5542 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5543 send keepalive packets. The packet can be sent by clients,
5544 servers and routers.
5546 Added function silc_socket_set_heartbeat into the file
5547 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5548 If not set, the heartbeat is not performed. The actual
5549 heartbeat is implemented in the low level socket connection
5550 library. However, application is responsible of actually
5553 Added silc_server_send_heartbeat to send the actual heartbeat
5554 packet into silcd/packet_send.[ch]. Server now performs
5555 keepalive with all connections.
5557 * Added silc_task_get_first function into lib/silcutil/silctask.c
5558 to return the timeout task with shortest timeout. There was a bug
5559 in task unregistration that caused problems. TODO has been
5560 updated to include that task system must be rewritten.
5562 * The client library will now resolve the client information when
5563 receiving JOIN notify from server for client that we know but
5564 have incomplete information.
5566 * Rewrote parts of silc_server_remove_from_channels and
5567 silc_server_remove_from_one_channel as they did not remove the
5568 channel in some circumstances even though they should've.
5570 * Encryption problem encountered in server:
5572 The LEAVE command used to send the Channel Key packet to the
5573 router immediately after generating it. However, the code
5574 had earlier sent Remove Channel user packet but not immediately,
5575 ie. it was put to queue. The order of packets in the router
5576 was that Channel Key packet was first and Remove Channel User
5577 packet was second, even though they were encrypted in the
5578 reverse order. For this reason, MAC check failed. Now, this
5579 is fixed by not sending the Channel Key packet immediately but
5580 putting it to queue. However, this is more fundamental problem:
5581 packets that are in queue should actually not be encrypted
5582 because packets that are sent immediately gets encrypted
5583 actually with wrong IV (and thus MAC check fails). So, packets
5584 that are in queue should be encrypted when they are sent to
5585 the wire and not when they put to the queue.
5587 However, the problem is that the current system has not been
5588 designed to work that way. Instead, the packet is encrypted
5589 as soon as possible and left to the queue. The queue is then
5590 just purged into wire. There won't be any fixes for this
5591 any time soon. So, the current semantic for packet sending
5594 o If you send packet to remote host and do not force the send
5595 (the packet will be in queue) then all subsequent packets to the
5596 same remote host must also be put to the queue. Only after the
5597 queue has been purged is it safe again to force the packet
5600 o If you send all packets immediately then it safe to send
5601 any of subsequent packets through the queue, however, after
5602 the first packet is put to queue then any subsequent packets
5603 must also be put to the queue.
5605 Follow these rules and everything works fine.
5607 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Added new function silc_server_remove_clients_by_server to
5610 remove all client entries from ID list when the server connection
5611 is lost. In this case it is also important to invalidate all
5612 client entires as they hold the invalid server entry. This
5613 fixes fatal bug when server has lost connection and will reconnect
5616 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5618 * Made some sanity checks to silc_server_daemonise like to check
5619 whether the requested user and group actually exists.
5621 * Added sanity check to SKE's silc_ske_responder_finish to check
5622 that the public and private key actually is valid.
5624 * Invalidate the client's nickname when receiving Replace ID
5625 packet and the Client ID is being replaced. This means that the
5626 server will query the nickname if someone needs it (client)
5629 * Sort the ID Cache in client library when the ID Cache data
5630 has changed (needs sorting).
5632 * Do not allow for SILC client to create several connections to
5633 several servers. The client does not support windows right now
5634 and generating multiple connections causes weird behaviour.
5636 Irssi-silc client does support windows and can handle several
5637 connections without problems, see: www.irssi.org and SILC plugin.
5639 * Fixed some places where client was added to the IDList. The
5640 rule of thumb is following (in order to get everything right):
5641 If the client is directly connected local client then the
5642 `connection' argument must be set and `router' argument must be
5643 NULL to silc_idlist_add_client function. If the client is not
5644 directly connected client then the `router' argument must
5645 bet set and the `connection' argument must be NULL to the
5646 silc_idlist_add_client function.
5648 * The funtion silc_server_packet_send_local_channel actually did
5649 not check whether the client was locally connected or not. It
5650 does that now. Fixed a bug related to LEAVE command.
5652 * Fixed Remove Channel User payload parsing bug in server's
5653 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5655 * The server's silc_server_save_channel_key now checks also the
5656 global ID list for the channel as it might not be in the local
5657 list. Fixed a bug related to LEAVE command.
5659 * Is this the end of the [<unknown>] buglet that has been lurking
5660 around for a long time? A little for loop fix in server's
5661 silc_server_command_whois_parse that is used by both IDENTIFY
5662 and WHOIS command. At least, this was a clear bug and a cause
5663 of one type of [<unknown>] buglet.
5665 * WHOIS and IDENTIFY commands call the function
5666 silc_server_command_[whois/identify]_check function even if
5667 we are not router server.
5669 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5671 * Added --with-gmp configuration option. If set the GMP
5672 is always compiled in the SILC source tree. If not set then
5673 it is checked whether the system has the GMP3 installed. If
5674 it has then the GMP won't be compiled (the system's headers
5675 and library is used), if it doesn't have it then the GMP is
5676 compiled in the SILC source tree.
5678 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5680 * Changed RSA private exponent generation to what PKCS #1
5681 suggests. We try to find the smallest possible d by doing
5682 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5683 not security fix but optimization.
5685 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5687 * Added new config entry [Identity] to fork the server and run
5688 it as specific user and group. A patch from Bostik.
5690 * Imported Dotconf configuration library into lib/dotconf.
5691 This will be used to create the SILC configuration files later.
5692 It will appear in the distsribution after this commit.
5694 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5696 * A big code auditing weekend happening. Auditing code for
5697 obvious mistakes, bugs and errors. Also, removing any code
5700 Removed files for being obsolete:
5702 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5703 inline in the file lib/silcutil/silcbuffer.h)
5705 o lib/silcutil/silcbufutil.c (the header has inline versions)
5707 Changed code to fix possible error conditions:
5709 o The buffer formatting routines now check that the destination
5710 buffer really has enough space to add the data. This applies for
5711 both buffer formatting and unformatting
5712 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5713 unformatting was changed to accomodate following rules:
5714 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5715 sent to the function while XXX_*STRING will not allocate or copy
5716 the data into the buffer. Instead it sets the pointer from the
5717 buffer into the pointer sent as argument (XXX_*STRING used to
5718 require that the pointer must be allocated already). This change
5719 makes this whole thing a bit more consistent and more optimized
5720 (note that the data returned in the unformatting with XXX_*STRING
5721 must not be freed now). The routines return now -1 on error.
5723 o Tried to find all code that use buffer_format and buffer_unformat
5724 and added return value checking to prevent formatting and
5725 especially unformatting errors and possible subsequent fatal
5728 o Changed ske->x and ske->KEY to mallocated pointers in
5729 lib/silcske/silcske.h. Fixed possible data and memory leak.
5731 o Added return value checking to all *_parse* functions. Fixed
5732 many memory leaks as well.
5734 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5735 so that buffer overflows would not happen. All code now also
5736 checks the return value as it can fail.
5738 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5740 * Added reconnection support to server if the normal server looses
5741 its connection to the router (for example if router is rebooted).
5742 The server performs normal reconnection strategy implemented
5743 to the server. Affected file silcd/server.c.
5745 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5747 * Added new packet type SILC_PACKET_SET_MODE that is used to
5748 distribute the information about changed modes (for clients,
5749 channels and clients channel modes) to all routers in the
5750 network. Updated the protocol specification accordingly.
5752 Added functions into silcd/packet_send.c and
5753 silcd/packet_receive.c: silc_server_send_set_mode,
5754 silc_server_set_mode.
5756 Added new files silcmode.[ch] into lib/silccore that implements
5757 the encoding and decoding of Set Mode Payload. Added new type
5758 SilcSetModePayload. Moved the definitions of different modes
5759 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5761 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5763 * Oops, a little mistake in server's connection authentication
5764 protocol. The protocol is not ended with FAILURE but with
5765 SUCCESS if the authentication is Ok. :) Affected file is
5768 * Implemented NICK_CHANGE notify handling in server in the file
5769 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5770 the local clients on the channel. After the changing nickname
5771 in router environment snhould work and the [<unknown>] nickname
5772 should appear no more.
5774 The silc_server_replace_id function that receives the Replace ID
5775 payload now sends the NICK_CHANGE notify type also in the file
5776 silcd/packet_receive.c
5778 * Changed WHOIS and IDENTIFY command to support the maximum amount
5779 of arguments defined in protocol specs (3328 arguments). This
5780 fixed a bug that caused problems when there were more than three
5783 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5785 * Added extra parameter, command identifier, to the
5786 silc_client_send_command so that explicit command identifier
5789 Changed that ID list routines uses specific command identifier
5790 when sending WHOIS/IDENTIFY requests to the server so that they
5791 can be identified when the reply comes back.
5793 Affected files lib/silcclient/command.[ch],
5794 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5796 * Added `sender' argument to silc_server_packet_send_to_channel
5797 to indicaet the sender who originally sent the packet to us
5798 that we are now re-sending. Ignored if NULL. Affected file
5799 silcd/packet_send.[ch].
5801 * Added some server statistics support in silcd/server_internal.h
5802 SilcServerStatistics structure and around the server code. Also
5803 send some nice statistics information when client is connecting
5806 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * Fixed channel ID decoding in server's JOIN command reply in
5809 silcd/command_reply.c
5811 * Fixed braodcasting of replace ID payload to not to send it if
5812 we are standalone server in silcd/packet_receive.c.
5814 * Fixed all channel message sending routines to not to send
5815 packets to clients that has router set, since they are routed
5816 separately in the same function earlier. Affects file
5817 silcd/packet_send.c and all channel packet sending functions.
5819 * In USERS reply, res_argv[i] are not allocated, the table
5820 is allocated. Thus changed that free the table, not its
5823 * In server's whois_check and identify_check if the client is
5824 locally connected do not send any WHOIS commands - they are not
5827 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5829 * Fixed some minor bugs in client when sending WHOIS command. The
5830 arguments was in wrong order.
5832 * Removed statis function add_to_channel from server in
5833 silcd/command.c that was previously used with the joining but
5836 * Tested USERS command in router environment successfully with two
5837 routers, two servers and two clients.
5839 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5841 * Reorganized the USERS command and command reply in client library
5842 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5843 When the command is given by user we register a pending command
5844 callback that will reprocess the command after the reply has been
5845 received from the server. When reprocessing the packet we then
5846 display the information. Thus, the USERS information is displayed
5847 now in the command callback instead of in the command reply
5848 callback. The processing of the command is same as previously
5849 when server has sent the command reply in the JOINing process.
5851 * Added to USERS command in silcd/command_reply.c to join the client,
5852 we didn't use to know about, to the channel after we've created
5853 a client entry for it. Also, for clienet we did know already still
5854 check whether it is on the channel or not and add it if not.
5856 * Removed silc_server_command_join_notify as the function and its
5859 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5861 * Changed the client's pending command handling to the same as the
5862 server's pending command handling. It is also now possible to
5863 execute command reply functions from other command reply
5864 function as the function callbacks for commands and command
5865 replies are one and same. The pending commands are not static
5866 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5867 in client connection context. Thus, pending commands are server
5868 connection specific as it is convenient.
5870 Changed the function silc_client_command_pending and
5871 silc_client_command_pending_del and added new function
5872 silc_client_command_pending_check. Removed the
5873 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5876 * Added cmd_ident, current command identifier, to the client
5877 connection context in lib/silcclient/client.h to keep track on
5878 command identifiers used in command sending. Client's command reply
5879 function handling now supports the mandatory command identifiers.
5881 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5882 funtions in client to fully support pending command callbacks.
5884 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5885 as one of the arguments to the application in the command reply
5888 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5889 before first releasing SILC but came back. Now it is removed again
5890 and should come back nomore. The FORWARDED flag was used only
5891 by the JOINing procedure by forwarding the command packet to router.
5892 Now, the JOINing procedure has been changed to more generic (due
5893 to various router environment issues) and FORWARDED is not needed
5894 anymore for anything. The protocol specification is yet to be
5897 Now, removed silc_server_packet_forward from server and the flag
5898 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5900 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5902 * Renamed NAMES command to USERS command. The NAMES was named that
5903 due to historical reasons. Now it is renamed. Also, rewrote
5904 parts of the USERS command. The nickname list is not sent anymore
5905 by the server. Only Client ID and mode lists are sent in the USERS
5906 command. Changed this also to the protocol specification.
5908 The client now resolves the names and stuff after it receives
5909 the USERS list from the server when joining to the channel.
5911 * WHOIS and IDENTIFY commands has been changed to support multiple
5912 Client ID's per command. One can now search for multiple users
5913 in the network by sending only one WHOIS or IDENTIFY command.
5914 Changed the code and the protocol specifications.
5916 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5917 uses silc_server_command_whois_parse to parse the request. */
5919 * If normal server, do not parse the WHOIS and IDENTIFY requests
5920 before sending it to the router. Saves some time.
5922 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5924 * Fixed JOIN command on client library. Wrong number of arguments
5925 used to crash the client.
5927 * Added silc_server_channel_has_global function to check whether
5928 channel has global users or not.
5930 * Added silc_server_channel_has_local function to check whether channel
5931 has locally connected clients on the channel.
5933 * The silc_server_remove_from_one_channel now checks whether the
5934 channel has global users or not after given client was removed from
5935 the channel. It also checks whether the channel has local clients
5936 on the channel anymore. If it does not have then the channel entry
5937 is removed as it is not needed anymore.
5939 * The silc_server_notify now checks on JOIN notify whether the joining
5940 client is one of locally connected or global. If it is global then
5941 the channel has now global users on the channel and that is marked
5942 to the channel entry. Also, it now saves the global client to
5943 global list who is joining and JOINs it to the channel. This is
5944 for normal server, that is.
5946 Changed silc_server_send_notify_on_channel,
5947 silc_server_packet_relay_to_channel and
5948 silc_server_packet_send_to_channel check if we are normal server
5949 and client has router set (ie. global client) do not send the
5950 message to that client, as it is already routed to our router.
5952 * Implemented LEAVE notify type handling in silc_server_notify
5955 * Tested LEAVE command in router environment successfully. Tested
5956 with two routers, two servers and two clients.
5960 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5962 * Implemented SIGNOFF notify type handling in silc_server_notify
5965 * silc_server_remove_id now removes the client entry from all channels
5966 it has joined and thusly sends SIGNOFF notify type.
5968 * Rewrote the NAMES list generation in server by removing two excess
5969 loops. The lists are created now inside one loop.
5971 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * silc_server_remove_channel_user checks now also global list
5974 for channel and client.
5976 * silc_server_new_channel_user checks now both local and global
5977 list for channel and client. Fixed a bug in client id decoding.
5978 Used to decode wrong buffer.
5980 * silc_server_channel_message checks now both local and global
5981 list for channel entry.
5983 * Tested channel joining (hence JOIN) in router environment
5984 successfully. Tested with two routers, two servers and two
5987 * Tested channel message sending in router environment successfully.
5989 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5991 * Added silc_server_save_channel_key into server.[ch] to save the
5992 received channel key in Channel Key payload processing. It is
5993 also used in JOIN command reply handling.
5995 Equivalent function silc_client_save_channel_key added into
5996 client.[ch] into client library.
5998 * Changed JOIN command reply to send information whether the channel
5999 was created or not (is existing already) and the channel key
6000 payload. Changed protocol specs accordingly.
6002 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6003 the request was sent by ID and not by nickname. Crashed on
6006 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6008 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6009 now correctly save the received data.
6011 * silc_server_free_sock_user_data now notifies routers in the
6012 network about entities leaving the network.
6014 At the same time implemented functions silc_server_remove_id
6015 and silc_server_send_remove_id to receive and send REMOVE_ID
6016 packets. The packet is used to notify routers in the network
6017 about leaving entities. The ID removed will become invalid in
6020 * Added function silc_idlist_del_server into server. Removes and
6021 free's server entry from ID list.
6023 * silc_server_private_message function now checks, if we are router,
6024 that the destination ID really is valid ID, naturally.
6026 * In router when NEW_ID packet is received (for new client) the
6027 hash of the Client ID is saved in the ID Cache but the
6028 client->nickname is set to NULL, instead of putting the hash
6031 IDENTIFY command now also checks that client->nickname must be
6032 valid. If it is not if will request the data from the server who
6033 owns the client. Added new function
6034 silc_server_command_identify_check.
6036 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6037 to set the command to already allocated Command Payload.
6039 * Tested private message sending in router environment with two
6040 routers, two servers and two clients. Fixed minor bugs and now
6043 * Fixed segfault from client's NAMES command. Used to crash if
6046 * Forwarded packets must not be routed even if it is not destined
6047 to the receiver. Changed server code comply with this.
6049 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6051 * Added `require_reverse_mapping' boolean value to ServerParams
6052 structure. If TRUE (not default) the server will require that
6053 the connecting host has fully qualified domain name.
6055 If the reverse mapping is not required and hostname could not be
6056 found the IP address is used as hostname.
6058 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6060 * Implemented version string checking to both client and server.
6061 The check is incomplete currently due to the abnormal version
6062 strings used in development version of SILC.
6064 * Changed all command functions in server to use the new
6067 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6069 * Changed char *data to unsigned char *data in ID Cache system to
6070 support binary data as ID Cache data. Changed code to support
6071 binary data in lib/silccore/idcache.c.
6073 * Renamed silc_server_packet_relay_command_reply to
6074 silc_server_command_reply as it is normal packet receiving
6075 function. Rewrote the function to accept command replys for
6076 servers and not only for clients.
6078 * Mark remote router always as registered server if we are connecting
6079 to it. Otherwise, commands sent by the router to us are ignored.
6081 * All ID List find routines now returns the ID Cache Entry pointer
6082 as well if requested.
6084 * WHOIS command works now in router environment, tested with two
6085 routers, two servers and two clients.
6087 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6088 in router environment (as it is almost equivalent to WHOIS) but
6089 hasn't been tested thoroughly. Added new functions:
6091 silc_server_command_identify_parse
6092 silc_server_command_identify_send_reply
6093 silc_server_command_identify_from_client
6094 silc_server_command_identify_from_server
6096 * Disabled route cache adding because adding two different ID's with
6097 same IP replaces the old cache entry thus giving wrong route.
6098 The entry->router->connection is always the fastest route anyway
6099 so route cache may not be needed. Of course, new routes maybe
6100 established after receiving the ID when the entry->router->connection
6101 might not be anymore the most optimal.
6103 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6105 * Add route cache for received ID for fast routing.
6107 * Added silc_server_packet_route to route received packet on router
6108 that is not destined to us.
6110 * Renamed silc_server_get_route to silc_server_route_get.
6112 * Added id_string and id_string_len fields into SilcServer to
6113 include encoded ServerID for fast comparing without excess
6114 encoding of the ID's.
6116 * Cleaned up WHOIS command on server side. Added following static
6119 silc_server_command_whois_parse
6120 silc_server_command_whois_check
6121 silc_server_command_whois_send_reply
6122 silc_server_command_whois_from_client
6123 silc_server_command_whois_from_server
6125 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6126 arguments in command replies. All command functions should be
6127 updated to use this macro.
6129 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6131 * Minor typo fixes on command reply handling on server.
6133 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6135 * Added silc_server_command_add_to_channel internal routine to add
6136 the client to the channel after router has created the channel and
6137 sent command reply to the server.
6139 * Added generic silc_server_send_command to send any command from
6142 * Use static buffer with ID rendering instead of duplicating data.
6144 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6146 * Fixed a channel user mode bug when joining to a channel server gave
6147 everybody channel founder rights, oops.
6149 * We mark ourselves as the router of the incoming server connection
6150 if we are router ourselves. This way we can check in some packet
6151 sending functions whether it is locally connected server. For
6152 incoming router connections we put NULL.
6154 * For router sending packets locally means now always sending the
6155 packet cell wide; to local clients and local servers. For normal
6156 server sending packet locally means sending it to only local
6159 * Fixed the JOIN command to really work in router environment. If the
6160 channel is created it is always created by the router. Router is
6161 also responsible of making the initial joining to the channel,
6162 sending JOIN notify to the sending server and distributing
6163 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6164 does not exist server doesn't do anything else but forward the
6165 command to the router which performs everything.
6167 * Added silc_server_send_channel_key function to send the Channel Key
6170 * Added silc_server_create_channel_key to create new channel key. The
6171 channel key is now re-generated everytime someone joins or leaves
6172 a channel, as protocol dictates. Note: channel->key_len is the
6175 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6177 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6178 packet_receive.[ch] to separate packet sending and receiving
6179 routines. The server.[ch] now includes everything else including
6180 actual packet processing (writing and reading data) and other
6183 Renamed silc_server_private_message_send_internal to
6184 silc_server_send_private_message. The routine is still though
6185 used only to relay private messages as server does not send
6186 private messages itself.
6188 Renamed silc_server_new_channel to silc_server_create_new_channel
6189 and added new function sicl_server_new_channel that handles the
6190 incoming New Channel packet. Added also new sending function
6191 silc_server_send_new_channel to send New Channel Payload.
6193 * Added new function silc_server_notify to process incoming notify
6194 packet to the server/router. Server may then relay the notify
6195 to clients if needed.
6197 * Added new function silc_server_new_channel_user to process incoming
6198 New Channel User packet. Router will redistribute the packet and
6199 send JOIN notify to its local clients and locally connected servers
6200 if needed. Normal server will send JOIN notify to its local client
6201 on same channel when received this packet. Added also corresponding
6202 sending function silc_server_send_new_channel_user to sent the
6205 * Added boolean route argument to send_notif_to_channel and
6206 packet_send_to_channel functions to attempt to route the packet
6207 if it is TRUE and send only locally if it is FALSE.
6209 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6211 * silc_server_replace_id now broadcasts the received replace ID
6212 packet if it is not broadcast packet already. The router must
6213 broadcast to inform other routers about changed ID.
6215 * Added backpointer to server's router into SilcServer context in
6216 silcd/server_internal.h.
6218 * Fixed silc_server_packet_broadcast to send correct broadcast
6221 * The channel key is now distributed to the local client as soon
6222 as it is received from the router (in router environment) so that
6223 no other packet may be sent for the channel until client has
6226 * silc_server_remove_channel_user now broadcasts the received
6227 Remove Channel User packet if it is not broadcast packet already.
6228 The router must broadcast to inform other routers about removed
6231 * Added users field into SilcPacketContext that is a reference count
6232 of the context. One can increase the reference count by calling
6233 silc_packet_context_dup which is now changed to just increase the
6234 reference count instead of duplicating the data. The reference
6235 count is decresed by calling silc_packet_context_free that will
6236 free the data after the reference count hits zero.
6238 For now on the packet context and everything allocated into it
6239 (including the raw packet from network) must be freed by calling
6240 the new silc_packet_context_free function. Added also new function
6241 silc_packet_context_alloc that must be used now to allocate the
6242 context. This also means that if a routine is asynchronous from
6243 silc_[client/server]_packet_parse_type the packet context must
6244 be duplicated by calling silc_packet_context_dup. Otherwise it
6245 gets free'd after silc_[client/server]_packet_parse_type returns.
6246 Also, one must remember that if packet is duplicated then its
6247 reference count must be decresed by calling the free function as
6248 many times as it was duplicated.
6250 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6251 from both client and server.
6253 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6255 * Made joining to a channel working in router environment.
6257 * Cleaned up JOIN command on server side and create function
6258 silc_server_command_join_channel internal routine to make the
6261 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6263 * Changed silc_command_pending list to SilcDList. Also, added
6264 `ident' field to SilcServerCommandPending structure to identify
6265 the reply and to call correct callback.
6267 Added silc_server_command_pending_check function to replace the
6268 corresnponding macro. The silc_command_pending list is not
6271 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6272 to set identifier to previously allocated Command Payload. It
6273 is used to set identifier for command when resending Command
6276 * Added silc_command_payload_encode_payload to encode Command
6277 Payload buffer from SilcCommandPayload structure.
6279 * Added silc_argument_payload_encode_payload to encode Argument
6280 payload buffer from SilcArgumentPayload structure.
6282 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6284 * Changed WHOIS command to support router connection on server side.
6285 The whois request is always sent to router unless the server is
6286 standalone server. After server has received the reply from the
6287 router will it send the reply to the client.
6289 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6290 broadcast received broadcast packet. The function is used only
6291 by router. The broadcast packet is always sent to the router's
6294 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6295 render given ID to printable string, for log files for example.
6297 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6299 * Made basic router to router connections working. At least they
6300 can now connect to each other but nothing really works the way
6301 they are supposed - yet.
6303 * Added new initiator token to RouterConnection configuration
6304 file in silcd/serverconfig.[ch]. It is used to tell whether we
6305 are the initiator to the remote router or whether we'll expect
6306 the other end to connect.
6308 * Moved registering of listener task to silc_server_init, hence
6309 the server starts listenning as soon as it is run, even if it
6310 does not have connections to other routers. Let's see how well
6313 * Changed default connection retry timeouts for more suitable in
6316 * Removed cipher and such arguments from silc_idlist_add_client
6317 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6318 Added new function silc_idlist_add_data to add the keys and stuff
6321 * Added SilcIDListData structure and added it to SilcClientEntry
6322 and SilcServerEntry as their first field in the structure. This
6323 way we can explicitly cast the ID entries to the SilcIDListData
6324 structure and get common data for the entries. In past, we had
6325 to first check what type of connection it is and then cast it to
6326 correct ID entry type. Now, we can directly cast the opaque
6327 pointer to the SilcIDListData (no matter what ID entry it actually
6328 is) and get the data needed.
6330 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6332 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6333 in some circumstances even if threre were timeout tasks, though not
6334 IO tasks, but tasks anyway. Now fixed.
6336 * Defined SilcServerConnection structure to hold connection specific
6337 stuff about directly connected servers and routers. The definition
6338 is currently in silcd/server_internal.h. I thought about having
6339 a bit more important role fro this struct but for now it is used
6340 only when connecting to other server (or router actually).
6342 * Added connecting retry support in server when connecting to
6343 router(s). The retry feature implement exponential backoff
6344 algorithm. Also, added SilcServerParams structure to hold default
6345 parameters for server. For now, it include these retry settings
6346 and are hard coded. After server is moded to be as Silc Server
6347 Library this structure will be more important.
6349 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6351 * Changed client librarys channel->clients table to SilcList and
6352 changed code accordingly.
6354 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6356 * Changed client's channel table to SilcList and changed code
6357 accordingly. Also changed SilcChannelClientEntry to include back-
6358 pointer to the channel so that client entry can use that structure
6359 as list as well and we have fast cross-reference to the channel.
6360 This change dramatically decreased the complexity of channel
6361 handling with client entry and vice versa (removed one extra
6362 loop when searching for channel entry from many functions).
6364 * Changed server->sim from table to SilcDList and changed code
6367 * NAMES command can now be used from user interface. It will show
6368 the user list on the channel, neatly.
6370 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6371 Code now saves realname of the user if it becomes available.
6373 * Renamed configure.in to configure.in.pre and made ./prepare
6374 script to automatically add correct version string to
6375 configure.in which it creates from configure.in.pre.
6377 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6379 * NAMES command reply now shows users mode with the nickname when
6382 * Moved silc_client_ch[u]mode[_char] functions from
6383 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6384 place sucks, they are utility functions and should be in some
6387 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6389 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6392 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6396 * Added TRQ (efficient deque and list library) into lib/trq. This is
6397 a very good list library that is currently used in the SILC. Defined
6398 SilcList API over the library because I didn't like the API very
6399 much. See lib/trq/silclist.h for the API and examples of how to
6400 use the API. Fixed various places in the code to use the new
6401 SilcList API. The SilcList is meant for lists that has a structure
6402 already defined as a list. It is not suitable to add just some
6403 context to the list (in TRQ, the context is the list actually).
6405 So, I defined SilcDList that can be used for the purpose where
6406 predefined list structure does not exit. This can be used as
6407 such list. Now some context just can be added to the SilcDList.
6408 Currently this list is not used in the SILC just yet, though there
6409 are a lot places where this can replace dynamically allocated
6410 tables and I will fix these places, later, to use SilcDList.
6411 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6412 and use TRQ internally).
6414 Also fixed some annoying warning messages that the original TRQ
6415 code generated. Also minor changes to TRQ's Makefile.in.
6417 * Added support for querying by Client ID to both WHOIS and
6418 IDENTIFY commands into server, as required by the protocol.
6420 * Removed method function pointers from SilcBuffer structure. They
6421 weren't used to anything and just increased the context size for
6422 no good reason. This change also made silc_buffer_alloc and
6423 silc_buffer_free functions inline functions.
6425 * Disabled command flooding detection support until it's fixed so
6426 that it accepts commands in but does not execute them more than once
6429 * Added silc_net_localhost(), to return local hostname, into
6430 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6431 that must be initialized before calling silc_client_init.
6433 * Added new function: silc_server_send_notify_on_channels to send
6434 notify messages to all channels client has joined. It is assured
6435 that the message is sent only once per client.
6437 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6438 lib/silcutil/silcutil.[ch] as silc_format function. The new
6439 function is generic and is used by server as well, not only by
6440 the logging routines.
6442 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6443 the provided version string was not acceptable. Added new function:
6444 silc_ske_check_version into lib/silcske/silcske.h. The function
6445 must be implemented by the application (client or server) and it
6446 does not reside in the SKE library. The function checks the version
6447 string remote end sent.
6449 * Added back pointers (to opaque context and to SilcSocketConnection)
6450 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6452 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6453 duplicate packet context structure.
6455 * Changed `notify' client operation to send same arguments as client
6456 receives from server except for ID's. ID's are mapped to correct
6457 ID entry and that is returned. Also, if channel entry is not sent
6458 by server but the notify is for channel the channel entry is sent
6459 to application (otherwise application doesn't know that it is for
6460 channel (library gets it from packet's Destination ID)).
6462 * Added silc_client_remove_from_channels into client library to
6463 remove a client from all channels it has joined to. Used when
6464 received SIGNOFF notify from server. Added also new function
6465 silc_client_replace_from_channels to replace old ID entry with
6466 new ID entry on all channels. Used when received NICK_CHANGE
6469 * Fixed ID Cache list handling in silc_idlist_get_client in
6470 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6471 to get (or query) client by ID.
6473 * Updated TODO list.
6475 * Added connection authentication status message defined by the
6476 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6477 support for these into the code in client and server side.
6479 * Added generic function silc_client_send_command to send any command
6480 with variable argument list. Application should use this function
6481 to send commands if the command functions provided by the library
6482 does not suite for the application's user interface needs.
6484 * Added new `failure' client operation. Application is notified about
6485 received failure packet if client is executing a protocol. In this
6486 case the protocol's execution has failed.
6488 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6489 is required by the protocol.
6491 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6492 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6495 * Added status flag to SilcSKE object to indicate realtime status
6496 of the SKE protocol.
6498 * Application receives now exactly same command reply arguments as
6499 the library receives from server. However, if ID is received the
6500 corresponding ID entry is returned to the application (eg. Client
6501 ID is mapped to correct SilcClientEntry entry and that is returned).
6502 Changed command_reply client operation due to this change.
6504 * Changed all ID's in commands and in command replys as ID Payloads.
6505 Change affected both client and server side codes.
6507 All ID's sent in SILC network (with execption of ID's in SILC
6508 Packet header) are sent in ID Payload to support variable length
6511 * Server now notifies nick changes and notifies all clients on
6512 the channels about the new nickname (about the new Client ID,
6515 * Implemented CMODE command to change channel modes. Supports all
6516 channel modes defined by the protocol specs except ban and invite
6517 lists. (Also, private channel key mode is supported but support for
6518 setting private channel key in client is missing, thus, this mode
6519 has no effect on client side (except that server requires that the
6520 client uses private channel key and normal channel traffic does not
6523 Also, invite mode works per se, but INVITE command does not work
6524 yet correctly, so you can set channel as invite only channel but
6525 inviting clients to the channel does not work (it is yet to be
6526 thought what's the best way to do it).
6528 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6529 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6530 Implemented CUMODE command to change user's mode on the channel.
6531 Supports all modes defined by the protocol specs.
6533 * Added NAMES command reply to return users modes on the channel.
6535 * Removed unnecessary and slow ciphers from lib/silccrypt.
6537 * Set SO_KEEPALIVE option to connection sockets by default.
6539 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6541 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6542 redefined the Notify Payload into protocol specs.
6544 * Added silc_id_payload_parse_id to get ID directly from raw
6547 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6549 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6550 accept searching by Client ID as well.
6552 * Added support for LEAVE and SIGNOFF notify types in client library.
6554 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6555 to parse ID Payload from raw data.
6557 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6559 * Added flags parameter into silc_ske_assemble_security_properties
6560 function in lib/silcske/silcske.[ch].
6562 * Changed notify client operation to fit better for notify messages
6563 sent by server. The notify payload received from server is now
6564 passed to the application (after parsing it to SilcNotifyPayload).
6565 It is application's responsibility to retrieve the arguments
6566 from the payload and show the message the way it wants. The message
6567 sent by server is implementation specific.
6569 * Changed public keys to comply with the protocol specification.
6570 Old public keys are not supported anymore and are not compatible.
6572 * Removed nickname from Channel Payload as the latest draft removed
6573 it. The client must resolve the nickname from the NAMES command
6574 reply received when it joined the channel.
6576 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6578 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6580 * Fixed some errors in protocol specification drafts.
6582 * Created lib/silccore/silcnotify.c to implement Notify Payload
6583 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6584 generic payloads described by protocol specifications. The file
6585 includes implementations for ID Payload and Argument Payload.
6587 * Changed Command Payload implementation to use the new Argument
6588 Payload. Changed command_xxxx_payload to command_payload_xxxx
6589 to comply with SILC coding conventions.
6591 * Added suppport for Argument Payload handling in Notify Payload
6592 implementation as protocol requires it. Added the new support
6593 into server and client lib as well.
6595 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6597 * Added support for multiple nicknames on same channel. [n] is
6598 added locally to the nickname if there are more than one same
6599 nicknames on the channel.
6601 * Server now sends all nicknames that matched WHOIS request.
6602 Client also shows the list received from server.
6604 * Added TOPIC command to client side. User can now set and show
6605 current topic on channel.
6607 * Added MOTD command to client and server. Also, server sends the
6608 motd when client connects to the server.
6610 * Changed version strings to comply ISO 8601.
6612 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6614 * Fixed protocol error handling in client library. It should now
6615 cope even if the SKE fails for some reason.
6617 * Made new protocol specification drafts for submitting to IETF.
6619 * Implemented TOPIC command to server in silcd/command.c.
6621 * Added two new notify types into lib/silccore/silcnotify.h:
6622 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6623 notify nickname change and topic setting/change on a channel.
6625 * API change of command_reply operation in client library. The
6626 application gets now the status type received from server as well.
6628 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6630 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6632 * Cras fixed and optimized the packet handling even further and
6633 it should work now. Minor change to the prototype of function
6634 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6636 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6638 * Added new function into lib/silcutil/silcschedule.[ch]:
6639 silc_schedule_with_fd to select() a specified fd. The function
6640 returns after timeout expires or data arrives or goes. The
6641 function is used by packet routines to wait that all data is
6642 received from network.
6644 * Fixed data reading from network in lib/silccore/silcpacket.c.
6645 The code now assures that all data is read from the fd and then
6646 continues packet processing. This was a bug fix since the code
6647 used to drop some data in some circumstances.
6649 * Added new function into lib/silcclient/client.[ch]:
6650 silc_client_start_key_exchange to start key exchange after
6651 connection has been established to server. The code internally
6652 now uses this funtion but its main purpose was to provide it
6653 for applications that perform their own connecting. After
6654 application has created a connection it merely calls this
6655 function to start the key exchange between client and server.
6656 The library takes care of everything else after that.
6658 Updated also lib/silcclient/README to explain the usage of
6661 * Do not send to application information that connection has
6662 been established. Application gets notified it by connect
6665 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6667 * Applied cras's patch to add silc_schedule_one function. The
6668 function runs scheduler once and returns.
6670 * Fixed the scheduler after cras messed it up. The timeout
6671 handling works now as it's supposed to work.
6673 * Added into lib/silccore/ silcnotify.h to include notify
6674 message types support. Changed silc_server_send_notify*
6675 functions, in server.[ch], to support those new notify types.
6676 Added the support for the notify types into client library,
6677 as well. Added new notify client operation into ops.h in
6680 * Changed silc_server_packet_send_to_channel to send normal
6681 packets instead of just channel message packets. The function
6682 is now used to send the notify packets to channels. It is not
6683 used to send channel message packets anymore, as server never
6686 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6687 va_arg()s as it seems to require it nowadays. I guess, if SILC
6688 is compiled with older va_arg() the new code should work anyway.
6690 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6692 * Splitted core library. Core library (lib/silccore) includes
6693 now only SILC protocol specific core (and common) components.
6694 Created new utility library (lib/silcutil) that includes more
6695 generic purpose stuff. The stuff for util library was taken
6696 from the old core library. This was minor and easy split.
6698 * Created SILC Client Library (lib/silcclient) that includes
6699 implementation of the SILC client without user interface. This
6700 was major move from silc/ directory. The code has been changed
6701 so that it is transparent towards the user interface. The
6702 silc/ directory includes now the same user interface as before
6703 and it uses the new client library. Read lib/silcclient/README.
6704 Basicly, the client library performs everything else related
6705 to SILC except user interface handling. Also, configuration
6706 files are considered to be part of user interface and library
6707 does not handle them.
6709 This change also changed a lot of structures, function naming etc.
6710 Most important change was that SilcClientWindow object was
6711 renamed to SilcClientConnection in the client library. Created
6712 also new file lib/silcclient/ops.h. Also added new files
6713 silc/local_command.[ch] and silc/client_ops.[ch].
6715 All these changes were made to make it easier for user interface
6716 designers to create what ever user interface for the SILC client
6719 It is also expected that the server will be moved to lib
6720 directory as well and SILC Server Library will be created;
6721 sometimes in the future.
6723 * Removed Local commands from lib/silccore/silccommand.h as
6724 they are application specific and new client library does not
6725 handle any of those anymore.
6727 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6728 old client implementation in silc/.
6730 * Added support for callback functions in SILC_LOG_* macros.
6731 Application can now set its own callbacks that will be called
6732 instead of using the default functions that will always print
6733 the debug messages to stderr (or stdout). Also, debugging can
6734 now be disabled by setting silc_debug to FALSE and re-enabled by
6735 setting it to TRUE. Note, that logging will still work even
6736 if debugging is disabled.
6738 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6739 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6740 silc_log_reset_debug_callbacks.
6742 * To enable debugging in silc client one must give now -d
6743 option on command line.
6745 * Changed silc_schedule_init to automatically allocate task queues
6746 if they are not allocated before calling it.
6748 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6750 * Added GMP 3.1 into math library.
6752 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6754 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6755 a channel in SILC network. The packet is used by servers and
6756 routers to notify other routers that user has left a channel.
6757 This little feature was missing until now. Added the feature
6758 to protocol specification as well.
6760 Added functions: silc_server_send_remove_channel_user and
6761 silc_server_remove_channel_user into server.[ch].
6763 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6764 lib/silccore/silcpacket.h. However, they are not implemented
6767 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6769 * Fixed joining to a channel and sending channel messages
6770 between server and router. The channel message sending should
6771 now work inside a cell.
6773 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6775 * Fixed the private message sending between server and router.
6776 The private message sending should now work inside a cell.
6778 * Added silc_server_replace_id into server.[ch] to replace
6779 existing ID in the SILC network.
6781 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6782 and silc_idlist_replace_server_id into idlist.[ch] in server.
6784 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6786 * Fixed the server to server connections. Server can again now
6787 connect to router. Router to router connections probably does
6790 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6792 * Added dynamic protocol registering support. Now protocols can
6793 registered and unregistered on the fly. Patch by cras.
6795 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6797 * Added lib/contrib directory to hold routines that some platforms
6798 don't have but are needed by SILC.
6800 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6801 into lin/contrib to provide getopt() and getopt_long() for
6802 those who don't have it.
6804 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6806 * Added AWAY command to client. When away message is set and
6807 client receives a private message packet the client automatically
6808 replies to the sender with the away message.
6810 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6811 bug seemed to be the cause of recent problems when compiling
6814 * Added version detection support to SKE protocol specification
6815 and added the new changes to the SKE implementation as well.
6816 There were other minor changes in the SKE protocol as well.
6818 Many changes in lib/silcske/silcske.[ch] and in
6819 lib/silcske/payload.[ch].
6821 * Added ^U functionality, clear input line. Patch from cras.
6823 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6825 * Mainly small bugfixes on core library. Fixed some debugging
6826 logging and buffer overflow in silclog.c.
6828 * Updated config.sub and config.guess on the distribution tree.
6830 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6832 * Added command lagging support in server. Client may execute
6833 commands now only once in two seconds.
6835 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6837 * Optimized packet reception. MAC computation and checking is now
6838 also more optimized. A lot previously duplicated code is now
6839 used as generic by both client and server.
6841 * Fixed key pair generation in clientutil.c
6843 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6845 * Added into lib/silccore/silcbufutil.[ch] new function;
6846 silc_buffer_realloc.
6848 * Moved generic packet sending/encryption functions to
6849 lib/silccore/silcpacket.[ch] from client and server. Some
6850 rewriting of the functions.
6852 * Moved all generic packet reception/decryption functions to
6853 lib/silccore/silcpacket.[ch] from client and server. The
6854 packet processing is now much cleaner in both client and server.
6855 These were major changes in both client and server.
6857 * Created many common functions in server to do packet sending.
6858 Previously code were duplicated a lot, this has been removed
6861 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6863 * Rewrote major parts of the ID cache system. Don't know
6864 whether it is better now or not but at least the API is more
6867 * Major rewrite on ID cache stuff on client because of the ID
6868 cache API changes. Added idlist.c to client.
6870 * Also major rewrite on ID cache stuff on server as well.
6871 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6872 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6873 in hand, instead they are all put into the ID cache system now.
6874 All server_idlist_* routines uses ID cache now instead of
6875 traversing its own lists (those lists does not exist anymore).
6876 SilcIDList though still exists. Also, SilcXXXEntry's are
6879 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6881 * Finally made the SKE implementation compliant to the protocol
6882 specification. All mp integers are now binary encoded as
6883 opposed being HEX encoded.
6885 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6888 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6889 functions: silc_[encode/decode]_pem. Also added function
6890 silc_encode_pem_file to PEM encode with newlines ('\n') for
6893 * SILC public keys are now encoded either PEM or binary. Same
6894 option is for private keys as well. By default private keys
6895 are binary encoded and public keys PEM encoded. Silly HEX
6896 encoding were removed.
6898 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6899 function to create fingerprints.
6901 * Fixed a bug in SHA1; does not change the original data anymore.
6903 * Partly implemented INFO command on client and server side.
6904 Fixed CLEAR command. Changes to SERVER command; show current
6905 server(s) when giving command without arguments. Added
6906 VERSION command to client.
6908 * Added check to server that unregistered connections cannot
6909 execute commands (unless it is specificly allowed).
6911 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6913 * Fixed screen refresh.
6915 * Fixed channel joining bug from client. On some circumstances
6916 client tried to join to a channel it had already joined.
6918 * Added public key verification process into client's protocol.c.
6919 The client now verifies the public key from user and saves
6920 it into ~./silc/serverkeys/ directory.
6922 Added into: clientutil.[ch]: silc_client_verify_server_key.
6924 * Changed SKE protocol's silc_ske_initiator_finish function
6925 to accept callback function that verifies the received public
6926 key. Removed old silc_ske_verify_public_key function.
6928 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6930 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6931 silc_pkcs_private_key[_data]_set.
6933 * Made the password and public authentication more cleaner in
6934 server's protocol.c.
6936 * Removed historic and obsolete protocol `channel_auth' from
6937 both client and server.
6939 * Removed wrong way of sending command status messages from
6940 server to client in server's command.c. The old way violated
6941 protocol specification.
6943 Changes to silccore/silccommand.[ch]: removed
6944 silc_command_encode_status_payload -> not needed anymore,
6945 changed silc_command_encode_payload_va to accept extra
6946 argument on variable argument list. The argument type must
6947 now be provided to the function. Also, added new function:
6948 silc_command_encode_reply_payload_va which is same as
6949 normal command_encode_payload_va except command status type
6950 is provided as extra argument.
6952 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6954 * Added ~./silc directory handling. The directory includes the
6955 public and private keys for the client.
6957 Added silc_client_check_silc_dir, silc_client_create_identifier
6958 and silc_client_load_keys.
6960 * Implemented SILC protocol compliant public key. Added public
6961 and private key saving to and loading from files.
6963 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6964 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6965 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6966 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6967 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6969 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6970 silc_pkcs_load_[public/private]_key.
6972 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6974 * Added silc_server_get_route (route.[ch]) to get connection
6975 data for the fastest route for given ID.
6977 * Implemented INVITE command on client and server. The command
6978 were re-defined in the SILC Protocol Specification and the
6979 implementation now complies with the specification.
6981 * Implemented PING command on client and server.
6983 * Implemented NAMES command on client and server. The server side
6984 supports currently only normal server not router server yet.
6985 Some changes to NAMES definition in SILC protocol specification.
6987 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6989 * Implemented LEAVE command on client and server.
6991 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6992 again. This change was made to the protocol as well. Server
6993 should not violate the protocol specification anymore.
6995 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6997 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6998 was tested. SOCKS4 was not but should work anyway.
