3 * Unified the serverconfig.[ch]'s helper function interface.
4 Affected file silcd/serverconfig.[ch].
6 * Removed doc/example_silc.conf.in since it is redundant.
7 The make install will now install irssi/silc.conf file.
9 * Added new Passphrase and Publickey authentication methods to
10 config file, allowing both public key and passphrase based
11 authentication to be set at the same time.
13 Added `prefer_passphrase_auth' setting in config file which
14 can be used to set to prefer passwd auth if both passwd and
15 public key is set. If not set, public key is preferred.
16 This has effect only when being initiator (responder will try
19 Added support for authentication with passphrase and public key
20 at the same time. The passphrase is tried first always since
21 it is faster to check.
23 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
25 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
27 * Merged the new SILC Config library, with the server parsing
28 support. Read the header file silcconfig.h or the toolkit
29 documentation for the news. Affected files are
30 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]
31 silcd/command.c silcd/packet_receive.c silcd/packet_send.c

49 Sat Feb 9 14:54:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
51 * Allow zero length channel messages inside the Channel Message
52 Payload. Affected file lib/silccore/silcchannel.c.
54 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
57 * Removed lib/silcclient/README and created HTML file
58 lib/silcclient/silcclient_using.html, which is now included
59 as part of Toolkit documentation.
61 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
63 * Fixed CUMODE_CHANGE notify handling to change the mode of
64 correct client. Affected file lib/silcclient/client_notify.c.
66 * Make silc_rng_alloc fail if it cannot allocate the sha1
67 hash algorithm. Affected file lib/silccrypt/silcrng.c.
69 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
71 * Fixed the file transfer's key agreement payload to include
72 zero port also if the hostname is NULL because it could not
75 Call file transfer monitor callback now also if error occurs
76 during key agreement protocol.
78 Changed the silc_client_file_send interface to return the
79 SilcClientFileError instead of session id. The session ID
80 is returned into pointer provided as argument.
82 Check that the file exists locally before sending the
83 file transfer request at all.
85 Affected file lib/silcclient/client_ftp.c, silcapi.h.
87 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
88 error than can occur while key agreement protocol. Affected
89 file lib/silcclient/silcapi.h.

92 is changed and +k mode is set in the channel. Affected file
93 irssi/src/silc/core/silc-channels.c.
95 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
96 SILC_LOG_WARNING to give out Warning and not Error. Affected
97 file lib/silcutil/silclog.c.
99 * Fixed the channel message payload decryption in the function
100 silc_channel_message_payload_decrypt to not modify the original
101 buffer before it is verified that the message decrypted
102 correctly. Otherwise, next time it is called with correct
103 channel key it won't encrypt since the payload is corrupted.
104 Affected file lib/silccore/silcchannel.c.
106 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
108 * Do not constantly resize the window. A fix patch by cras.

113 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
114 Affected file lib/silcutil/silcnet.c.
116 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
118 * Fixed a bug in hash table internal routine for traversing
119 the table with foreach callback. The current entry may
120 become invalid in the callback but it was referenced after
121 the callback returned.
123 Do not allow auto rehashing of hash table during the
124 silc_hash_table_foreach operation, for same reasons as it is
125 not allowed for SilcHashTableList. Affected files are
126 lib/silcutil/silchashtable.[ch].
128 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
130 * Defined DLLAPI into silcincludes.h and silcwin32.h for
131 Win32 DLL. extern's in header files are now declared with
134 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
136 * Fixed private message handling. It used some old code that
137 caused the client to crash. Affecte file is
138 lib/silcclient/client_prvmsg.c.
140 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
142 * Added function silc_client_add_channel,
143 silc_client_replace_channel_id, and removed functions
144 silc_client_new_channel_id and silc_idlist_get_channel_by_id
147 * Added cross reference of the joined channels to the
148 SilcClientEntry, and changed the SilcChannelEntry's
149 users list to SilcHashTable. The affected files are
150 lib/silcclient/idlist.[ch].
152 * Fixed a bug in hash table tarversing. While the hash table
153 is traversed with SilcHashTableList the table must not be
154 rehashed. It is now guaranteed that auto rehashable tables
155 are not rehashed while tarversing the list. Also defined that
156 silc_hash_table_rehash must not be called while tarversing
157 the table. Added function silc_hash_table_list_reset that must
158 be called after the tarversing is over. The affected files are
159 lib/silcutil/silchashtable.[ch].
161 * Changed all hash table traversing to call the new
162 silc_hash_table_list_reset in server and in client library.
164 * Added function silc_client_on_channel to return the
165 SilcChannelUser entry if the specified client entry is joined
166 on the specified channel. This is exported to application as
167 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
169 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
171 * Fixed founder regaining problem with JOIN command on normal
172 server. The notify for mode change must be sent always and
173 not only if !cmd->pending. Affected file silcd/command.c.
175 * Fixed the WHOWAS command's reply sending to support the
176 lists correctly. Affected file silcd/command.c.
178 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
180 * When sending JOIN command to router for processing the
181 sender's old command identifier was not saved back to the
182 sender's command context, fixed now. The affected file is
185 * Create the key in JOIN command of the router did not return
186 the channel key, added check for this. Affected file is
189 * Fixed a channel ID update bug in JOIN command reply. Do
190 not directly upgrade the ID but call the function
191 silc_idlist_replace_channel_id if the ID was changed.
192 Affected file silcd/command_reply.c.
194 * Fixed memory leaks from command calling if it would fail.
195 Affected file silcd/command.c.
197 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
199 * Applied patches from cras:
201 Memory leak fixes around libaries, irssi window resize fix,
202 new silclist.h and silcdlist.h, all extern inline changed to
205 * Removed dotconf from lib/dotconf, not needed anymore.
207 * Removed TRQ from lib/trq, not needed anymore.
209 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
210 with server connections. Later this will be configurable
211 in config file after new config file is done. Affected file
214 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
216 * Fixed a crash in server related to channel announcements.
217 Affected file silcd/server.c.
219 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
221 * Fixed memory leaks in silc_server_create_new_channel*
222 functions. Affected file silcd/server.c.
224 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
225 which ID was changed. This way the router will send the
226 user list for the channel again, and server won't be in
227 desync in some rare circumstances. Affected file is
228 silcd/packet_receive.c.
230 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
232 * Check for NULL socket pointer in the function
233 silc_server_packet_send_to_channel_real. Affected file
236 * Fixed the BAN notify handling to correctly remove ban
237 list. Affected file silcd/packet_receive.c.
239 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
241 * Fixed some header addition to Toolkit distribution in
242 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
244 * Added lib/silcclient/client_ops_example.h as an template
245 file for application programmers to quickly start using
246 the SilcClientOperation functions in their application.
247 Updated the lib/silcclient/README as well to tell about this
248 nice file made available.
250 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
252 * Call silc_server_remove_from_channels when removing client
253 entry when NO_SUCH_CLIENT_ID was received. Affected file
254 is silcd/command_reply.c.
256 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
258 * Added server & router operator statistics updating. Affected
259 file silcd/packet_receive.c and silcd/command.c.
261 * Fixed the SERVER_SIGNOFF notify handling on normal server
262 not to save the history information for clients. Same was
263 fixed earlier in remove_clients_by_server function, but not
264 here. Affected file silcd/packet_receive.c.
266 * Raised the default connection-retry count from 4 to 7 in
267 server. Affected file silcd/server.h.
269 * Cancel any possible reconnect timeouts when we start the
270 key exchange. Affected file silcd/server.c.
272 * Do not reconnect on connection failure when SCONNECT was
273 given. Affected files silcd/server.[ch].
275 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
277 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
279 * Fixed the NICK command to always give the unformatted
280 nickname to the one giving the NICK command. If unformatted
281 nickname is cached already it will be formatted and the
282 local entry will always get the unformatted nickname.
283 Affected file lib/silcclient/idlist.c.
285 * Fixed some double frees from client library commands.
286 Affected file is lib/silcclient/command.c.
288 * Fixed CUMODE command in server to assure that no one can
289 change founder's mode than the founder itself, there was a
290 little bug. Affected file silcd/command.c.
292 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
294 * Removed the SilcClientCommandDestructor from the client
295 libary, it is not needed anymore. Affected files are
296 lib/silcclient/silcapi.h, command[_reply].[ch],
297 client_notify, idlist.c.
299 * Fixed GETKEY command to first resolve client, and then
300 resolve the server only if the client was not found, instead
301 of resolving both at the same time. Affected file is
302 lib/silcclient/command.c.
304 * Added silc_client_start_key_exchange_cb and lookup the
305 remote hostname and IP address before starting the key
306 exchange with server. The affected file is
307 lib/silcclient/client.c.
309 * The server's public key is now saved using the IP address
310 of the server and not the servername for the filename.
311 The hostname public key filename is checked as an fall back
312 method if the IP address based filename is not found.
314 Fixed the GETKEY command to save the fetched server key
317 Print the remote server's hostname now when new key is
318 received during connection process. Affected file is
319 irssi/src/silc/core/client_ops.c.
321 * Return always our own public key to the client if it asks
322 for it with GETKEY command. Affected file silcd/command.c.
324 * Removed the use_auto_addr variable from default config
325 file since it was in wrong section. Affected file is
328 * Fixed TOPIC_CHANGE notification to not route it when it
329 was sent using silc_server_send_notify_to_channel function.
330 Affected file silcd/command.c.
332 * Fixed silc_server_send_notify_kicked to send the kicker's
333 Client ID also, it was missing. Affected files are
334 silcd/command.c, silcd/packet_send.[ch].
336 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
338 * Do not save client history information in SERVER_SIGNOFF.
339 Fixes the bug in normal server that it does not detect
340 the client becoming valid after the server becomes back
341 online. Affected file silcd/server_util.c.
343 * Added `sock_error' field into the SilcSocketConnection
344 context. When error occurs during socket operation (read
345 or write) the error is saved. Added also new function
346 silc_socket_get_error to return human readable socket error
347 message. Affected files are lib/silcutil/silcsockconn.[ch],
348 lib/silcutil/unix/silcunixsockconn.c, and
349 lib/silcutil/win32/silcwin32sockconn.c.
351 * The server now prints the socket error message in the
352 signoff for client. Affected file silcd/server.c.
354 * Fixed the `created' channel information sending from router
355 to server in JOIN command. Checks now whether the channel
356 really was created or not and set it according that.
358 Fixed the JOIN command to use the client entry's current
359 ID during the joining procedure instead of the one it sent
360 in the command (it is checked though), since it can change
361 between the packet processing and command processing, and
362 would just case unnecessary pain in the client end. Affected
363 file silcd/command.c.
365 * Fixed a channel key payload sending to use correct channel
366 ID when the server was forced to change the channel's ID by
367 router. Router sent the key payload with the old Channel ID.
368 Affected file silcd/packet_receive.c.
370 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
372 * Call silc_server_save_channel_key only if the key payload
373 was provided in the JOIN command's command reply. Affected
374 file silcd/command_reply.c.
376 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
378 * Fixed silc_mp_sizeinbase to return the value correctly with
379 MPI. Affected file lib/silcmath/mp_mpi.c.
381 * Fixed the stop_server signal to correctly stop the scheduler
382 and gracefully stop the server when SIGTERM or SIGINT signals
383 are received. Affected file silcd/silcd.c.
385 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
387 * Simple handling of TERM and HUP signals. Also added some log
388 flushing call around. Affected file is
391 * Fixed small bugs in silclog.c. Now buffering output will take
392 effect after 10 seconds since startup: This will ensure that
393 no important startup messages are lost. Also output redirection
394 will preserve original format ([Date] [Type] message).
395 Affected file is lib/silcutil/silclog.c.
397 * Added two options to the config file, in the logging section:
398 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
399 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
401 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
403 * Do not print the warning about log files not being initialized
404 more than once to avoid excess logging. Affected file is
405 lib/silcutil/silclog.c.
407 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
408 the SIM copying in make install in Makefile.am.pre.
410 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
412 * Rewritten silclog APIs. Globally interesting changes follows:
413 silc_log_set_files() changed to silc_log_set_file().
414 silc_log_set_callbacks() changed to silc_log_set_callback().
415 ROBOdoc documented silclog header file.
416 SilcLogCb now returns bool to wether inihibit the default
417 handler or not (to keep the old behaviour return always TRUE).
418 The new APIs should also fix the problem of the
419 silcd_error.log file that was written in the current directory.
422 Log files streams will remain opened after silc_log_set_file()
423 call, means less CPU usage notably on high traffic servers.
424 File streams are now full buffered, and flushed to the disk
425 every 5 minutes, lesses HD activity and CPU usage.
426 Messages can be redirected, allowing admins to configure
427 one single logfile for all server messages.
428 the silc_log_quick global variable to activate fast-logging.
429 Affected files lib/silcutil/silclog.[ch]
431 * Changed some code to conform new silclog APIs. Affected
432 files are doc/example_silcd.conf.in, silcd/server.c
433 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
436 * Fixed a memory leak that could occur in some situations.
437 Affected file silcd/serverconfig.c.
439 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
441 * Added the silc_client_del_client to remove the client from
442 all channels as well. Affected file lib/silcclient/idlist.c.
444 * Fixed the client library to correctly remove the client
445 from all channels when the client entry is being destroyed.
446 Affected file lib/silcclient/client_notify.c, command.c.
448 * Added auto-nicking support to the client library. If the
449 applicatio now sets client->nickname it will be sent to the
450 server after connecting by the library. This way for example
451 SILCNICK (or IRCNICK) environment variables will have effect
452 and always change the nickname automatically to whatever
453 it is wanted. Affected file lib/silcclient/client.[ch].
455 * Renamed silc_server_command_bad_chars to the
456 silc_server_name_bad_chars and moved it to the
457 silcd/server_util.[ch]. Added also new function
458 silc_server_name_modify_bad to return nickname that
459 includes bad characters as new nickname without those
460 bad characters. This check and modify is now used in
461 silc_server_new_client when the username is initially set
462 as nickname, so it must be checked to be valid nickname.
463 Affected file silcd/packet_receive.c.
465 * The nickname length is now taken from the packet for real
466 and not trusted to strlen() since it clearly can return
467 wrong length for nickname including bad characters. This
468 also applies to channel names. Affected file silcd/command.c.
470 * Removed the lib/silcsilm/modules directory. Modules are now
471 compiled into the lib/silcsim. Fixed the copying of the
472 modules to follow symbolic links in Makefile.am.pre.
474 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
476 * Fixed silc_string_regexify list creation. Fixes bugs with
477 BAN and INVITE commands in server. The affected file is
478 lib/silcutil/unix/silcunixutil.c.
480 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
482 * Removed the command destructor entirely from the server's
483 command and command reply routines. It is not needed, and
484 its usage was buggy and caused crashes. Affected files are
485 silcd/command[_reply].[ch].
487 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
489 * Cancel protocol and NULL sock->protocol if timeout
490 occurred during protocol. Affected file silcd/server.c.
492 * Cancel protocol timeouts always before calling the final
493 callback, to assure that after final callback is called
494 no other state will be called for the protocol anymore.
495 Affected file silcd/protocol.c.
497 * Print error log if incoming connection configuration could
498 not be found. Affected file silcd/server.c.
500 * Fixed JOIN command to correctly save the founder mode
501 to the client on normal SILC server, when the channel
502 was created by the router. Affected file silcd/command.c.
504 * Fixed LIST command (hopefully) to send correct reply
505 packets. Affected file silcd/command.c.
507 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
509 * The silc_packet_receive_process now returns FALSE if the
510 read data was invalid packet, and TRUE if it was ok.
512 The server now checks that if unauthenticated connection
513 sends data and its processing fails the server will close
514 the connection since it could be a malicious flooder.
516 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
518 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
520 * Make sure the warning about error opening a log file is
521 printed only once and not everytime it fails (produces
522 too much useless log). Affected file lib/silcutil/silclog.c.
524 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
526 * Made the silc_server_daemonise() function more readable.
527 Affected file silcd/server.c.
529 * Pid file is now optional, the user may comment it out from
530 the config file. Removed define SILC_SERVER_PID_FILE, we
531 don't need a default any longer. Affected file
532 configure.in.pre, lib/Makefile.am.pre.
534 * Make some use of the pid file. The server now dies at startup
535 if it detects a valid pid file on his path. The server would
536 die anyway in this circumstance, because of the bind() failure.
537 Affected file silcd/silcd.c.
539 * No longer compiling lib/dotconf.
541 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
543 * Fixed JOIN command parsing not to crash. Affected file
544 lib/silcclient/command.c.
546 * Fied the NICK_CHANGE notify to add the new client entry
547 even it is resolved. This removes an <[unknown]> nick
548 thingy bug in the client. Affected file is
549 lib/silcclient/client_notify.c.
551 * Do not try to allocate 0 bytes (efence does not like it)
552 in lib/silccore/silccomand.c when encoding payload.
554 * Do not take IRCNICK as nickname in Irssi SILC client since
555 it is not possible to set nickname before hand connecting
556 the server (TODO has an entry about adding auto-nicking
559 * Changed the silc_server_command_pending to check whether
560 there already exists an pending entry with the specified
561 command, command identifier and pending callback. This is
562 to fix IDENTIFY and WHOIS related crashes that may register
563 multiple pending commands with same identifier. Affected
564 file silcd/command.c.
566 * Fixed the server to reconnect to the router even if it
567 was already reconnecting and EOF was received. This to
568 fix a possibility that the server wouldn't ever try to
569 auto-reconnect to the router. Affected file silcd/server.c.
571 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
573 * Fixed the server's password authentication to use the
574 length of the locally saved password, and not the one
575 sent in the packet. Affected file silcd/protocol.c.
577 * Fixed same password authentication problem in the
578 Authentication Payload handling routines in
579 lib/silccore/silcauth.c.
581 * Yet another password authentication problem fixed with
582 channel password handling in silcd/command.c.
584 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
586 * If first character of string in silc_parse_userfqdn is '@'
587 then do not parse it. Affected file is
588 lib/silcutil/silcutil.c.
590 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
592 * Fixed minor bug in IDENTIFY command reply sending, which
593 caused various weird problems during JOIN when it was
594 resolving names for users. Affected file silcd/command.c.
596 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
598 * Fixed the IDENTIFY command reply sending to chech better valid
599 clients. It was possible to send incomplete list of replies.
600 Affected file silcd/command.c.
602 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
604 * Added silc_client_command[s]_[un]register functions now to
605 dynamically register the commands in client library. Removed
606 the static table of commands. This allows the client library
607 to call commands without causing the application to know about
608 what commands library has called.
610 Removed the INFO command reply kludge to detect when the command
611 was called by library. Now library use its own command reply
612 function for INFO command.
614 Added function silc_client_command_call to call a command.
615 Application can use it to call command, not access the structure
618 Now all commands that are sent by the client library (not
619 explicitly sent by application) use own command reply functions.
621 Affected files around lib/silcclient/ and in
622 irssi/src/silc/core/.
624 * Fixed the WHOIS command reply sending to chech better valid
625 clients. It was possible to send incomplete list of replies.
627 Fixed the WHOIS and IDENTIFY to send the request to router
628 if normal server did not do it and did not find any results.
630 Affected file silcd/command.c.
632 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
634 * Moved the internal data from SilcClient context into its
635 own file, not accesible to application. Affected files
636 lib/silcclient/client.h and lib/silcclient/client_internal.h,
637 and other files in client library.
639 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
641 * Added doc/examples installation target in Makefile.am.pre.
644 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
646 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
647 commands the found client entry will be removed from the
648 cache, after notifying application about the error. Affected
649 file lib/silcclient/command_reply.c.
651 * Changed the /MSG to check for exact nickname user gave, and
652 not let `nick' match `nick@host' if it is only one found. Now,
653 user must type the exact nickname (like nick@host2) even if
654 there are no more than one same nicks found. This is to avoid
655 a possibility of sending nickname to wrong nickname since
656 `nick' could match `nick@host'. Affected file is
657 irssi/src/core/silc-servers.c.
659 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
661 * Do not print "you are now server operator" or similar when
662 giving /away command. Affected files are
663 irssi/src/silc/core/client_ops.c, silc-servers.h.
665 * Made the silc_server_command_pending_error_check to send
666 the same command reply payload it received back to the
667 original sender of the command. This way all arguments
668 that was received by the server will be received by the
669 client too. Affected file silcd/command.c.
671 * Added the silc_idcache_add to return the created cache entry
672 to a pointer. Affected file lib/silccore/silcidcache.[ch].
674 * Add global clients to expire if they are not on any channel.
675 This is because normal server will never know if they signoff
676 if they are not on any channel. The cache expiry will take
677 case of these entries. This is done by normal servers only.
678 The affected files are silcd/command_reply.c,
679 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
681 * If server receives invalid ID notification for WHOIS or
682 IDENTIFY and the ID exists in the lists, it is removed.
683 Affected file silcd/command_reply.c.
685 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
686 in client then client entry that it matches is searched and
687 the nickname is printed on the screen for user. Affected
688 file irssi/src/silc/core/client_ops.c.
690 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
692 * Use cache entry expire time in the LIST command reply to
693 purge old entries from the cache after the LIST command
694 reply has been received. This way we don't have non-existent
695 entries in the cache for too long. Affected file is
696 silcd/command_reply.c.
698 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
700 * If we are normal server, and we've not resolved client info
701 in WHOIS or IDENTIFY from router, and it is global client,
702 we'll check whether it is on some channel. If it is not
703 then we cannot be sure about its validity and will resolve it
704 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
705 file silcd/command.c.
707 * Search channel by name (if possible) rather than by ID
708 in IDENTIFY command's command reply. Affected file is
709 silcd/command_reply.c.
711 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
713 * Distribute to the channel passphrase in CMODE_CHANGE notify.
714 Updated specs and implemented it. Affected file silcd/command.c,
715 silcd/packet_send.c and silcd/packet_receive.c.
717 * Implemented the <founder auth> payload handling in the JOIN
718 command. If provided all conditions for channel joining
719 except requirement to provide correct passphrase can be
720 overrided by the channel founder. Updated the protocol specs.
721 Affected file silcd/command.c.
723 Added support for founder auth in JOIN command in client
724 library. Fixed the parsing of the JOIN command now to support
725 all options as they should be. The affected file is
726 lib/silcclient/command.c.
728 * Optimized the WHOIS and IDENTIFY commands to send the request
729 to router only if it includes nicknames or other names. If
730 they include only IDs then check the local cache first before
731 routing. Affected file is silcd/command.c.
733 * Added channels topic announcements. Affected file is
734 silcd/packet_receive.c and silcd/server.c.
736 * Fixed the silc_server_send_notify_topic_set to really destine
737 the packet to channel. Affected file silcd/packet_send.c.
739 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
740 library. Affected file lib/silcclient/client_notify.c.
742 * Added UMODE announcements. Affected file silcd/server.c.
744 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
746 * Memory leak fixes in:
748 lib/silcutil/silcsockconn.c
749 lib/silcske/silcske.c
752 lib/silccrypt/silcpkcs.c
753 lib/silccore/silccommand.c
754 lib/silccore/silcidcache.c
759 * ROBOdoc documented the lib/silcske/groups.h file and a
760 bit changed the interface for better.
762 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
764 * Update the client entry context in the ID cache after
765 nick change. Affected file lib/silcclient/command.c.
766 Fixes the CUMODE command when regaining founder privileges,
767 and a little WHOIS problem.
769 * Fixed silc_net_gethostbyname to correctly call the
770 inet_ntop. Affected file lib/silcutil/silcnet.c.
772 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
774 * Added IPv6 support checking to the configure.in.pre, added
775 also --enable-ipv6 option to override the check. Affected
776 file configure.in.pre.
778 * The silc_thread_create now calls the start function
779 directly if threads support is not compiled in. Removes
780 ugly #ifdef's from generic code. Affected files are
781 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
783 * Added silc_net_gethostby[name/addr]_async to asynchronously
784 resolve. Affected files are lib/silcutil/silcnet.[ch].
786 * Added support for rendering IPv6 based server, client and
787 channel IDs. Affected file lib/silcutil/silcutil.c.
789 * Added support for creating IPv6 based server IDs. Affected
790 file is silcd/serverid.c.
792 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
794 * Added silc_net_gethostby[addr/name] into the
795 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
796 routines. Added silc_net_is_ip[4/6]. Affected file is
797 lib/silcutil/unix/silcunixnet.c. All routines that take
798 address as argument now supports both IPv4 and IPv6 addresses.
800 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
802 * Fixed LIST command reply sending in server. Affected file
805 * Server now sends the kicker's client ID in the KICK notify
806 to the kicked client. Affected file silcd/command.c.
808 * The client library now parses the kickers client ID and
809 UI displays it. Affected files lib/silcclient/client_notify.c
810 and irssi/src/silc/core/silc-channels.c, module-formats.c.
812 * Made all payload parsing function prototypes consistent.
813 They all take now const unsigned char * and uint32 pair as
814 the payload data instead of SilcBuffer. Changes all around
815 the source tree. Other unsigned char* -> const unsigned char*
816 changes around the tree as well.
818 * Optimized SFTP client and server packet sending not to
819 allocate new buffer for each packet but to recycle the
820 first allocated buffer. Affected files are
821 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
823 * Optimized the SFTP client to use SilcList instead of
824 SilcDList for requests, because it is faster. Affected file
825 is lib/silcsftp/sftp_client.c.
827 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
828 into lib/silccore/silcid.[ch].
830 Renamed silcpayload.[ch] into silcargument.[ch].
832 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
834 * If client entry is deleted with active key agreement
835 session, abort the session.
837 The silc_client_abort_key_agreement now calls the completion
838 callback with new SILC_KEY_AGREEMENT_ABORTED status.
840 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
843 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
845 * Don't use __restrict in older GCC's. Affected file is
846 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
848 * silc_net_localhost now attempts to reverse lookup the
849 IP/hostname. Affected file lib/silcutil/silcnet.c.
851 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
852 command. It can be used to gain founder privileges at
853 the same time when joining the channel.
855 Defined that the SILC_NOTIFY_TYPE_KICKED send the
856 kicker's client ID as well. Updated protocol specs.
858 Defined that the server must send SILC_COMMAND_IDENTIFY
859 command reply with error status to client who sent
860 private message with invalid client ID.
862 Updated the protocol specification.
864 * Added silc_server_send_command_reply to send any
865 command reply. Affected file silcd/packet_send.[ch].
867 * Added silc_id_payload_encode_data to encode ID payload
868 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
870 * The server now send IDENTIFY command reply with error
871 status if client ID in private message is invalid. Affected
872 file silcd/packet_receive.c.
874 * Save the server key file with server's IP address in
875 the filename instead of hostname. The affected file is
876 irssi/src/silc/core/client_ops.c.
878 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
880 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
883 * Added libtool support for compiling shared objects in
884 lib/silcsim. Affected file configure.in.pre and
885 lib/silcsim/Makefile.am. Original patch by cras.
887 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
889 * Pid file configuration, and server's config file fixes
890 patch by toma. Updated CREDITS file.
892 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
894 * Fixed silc_client_channel_message to not try to decrypt
895 the message twice if it resolved the destination client
896 information. This could cause of dropping one channel
897 message. Affected file lib/silcclient/client_channel.c.
899 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
901 * Added silc_client_run_one into lib/silcclient/silcapi.h and
902 lib/silcclient/client.c. This function is used when the SILC
903 Client is run under some other scheduler, or event loop or
904 main loop. On GUI applications, for example this may be
905 desired to used to run the client under the GUI application's
906 main loop. Typically the GUI application would register an
907 idle task that calls this function multiple times in a second
908 to quickly process the SILC specific data.
910 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
912 * Fixed silc_server_drop() for dropping the supplementary
913 groups as well, this could cause a security hole on some
916 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
918 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
921 * Write PID file after dropping privileges. Added -F option
922 to run server on foreground. A patch by debolaz.
923 Affected files silcd/server.c, silcd/silcd.c.
925 * Fixed MOTD to return the MOTD file server name. Affected
926 file silcd/command.c.
928 * Added INFO command reply handling to the Irssi SILC Client.
929 Affected file irssi/src/silc/core/client_ops.c.
931 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
933 * Fixed the silc_idcache_list_* routines to really support
934 the dynamic list. Fixes a crash. Affected file is
935 lib/silccore/silcidcache.c.
937 * Fixed the LIST command reply to really call LIST command's
938 pending callbacks. Affected file silcd/command_reply.c.
940 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
942 * Update conn->local_entry->nickname after giving NICK
943 command. Affected file lib/silcclient/command.c.
945 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
947 * Added the [pid] option to the silcd configuration file
949 Affected files: serverconfig.[ch] and silcd.c
951 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
953 * Save fingerprint in WHOIS command reply in server.
954 Affected file silcd/command_reply.c.
956 * Fixed NICK commands pending callback registration.
957 Affected file lib/silcclient/command.c.
959 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
961 * Use ++server->cmd_ident when sending commands in server,
962 instead of random number. Affected file silcd/command.c.
964 * Fixed GETKEY command reply to call actually GETKEY pending
965 command callbacks. Affected file silcd/command_reply.c.
967 * A bit stricter check for nicknames. Check for same nickname
968 in NICK command also. Affected file silcd/command.c.
970 * Do not call INFO command everytime client ID changes, only
971 during first connecting. Affected file lib/silcclient/client.c.
973 * Set the new nickname only after successful command reply for
974 NICK command is returned by server. Affected file
975 lib/silcclient/command.c.
977 * Remove nicknames from nicklist during server_signoff notify.
978 Should fix /NAMES bit more. The affected file is
979 irssi/src/silc/core/silc-channels.c.
981 * Added `fingerprint' field to the SilcIDListData in the
982 silcd/idlist.h to hold the fingerprint of the client's
985 Send the fingerprint of the client's public key in WHOIS
988 Affected files silcd/command.c, and silcd/idlist.[ch].
990 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
991 create fingerprint from given data.
993 * Show the fingerprint of the client's public key in WHOIS.
994 Affected files irssi/src/module-formats.[ch] and
995 irssi/src/silc/core/client_ops.c.
997 * Format the multiple same nicknames also during JOIN and
998 NICK_CHANGE notifys. Affected file is
999 lib/silcclient/client_notify.c.
1001 * Do not print error on screen for invalid private message
1002 payload since it can come if someone is sending private
1003 messages with wrong key. Affected file
1004 lib/silccore/silcprivate.c.
1006 * Fixed multiple concurrent /PING crash. Affected file
1007 lib/silcclient/command.c.
1009 * Changed the wrong ID encoding. All IP addresses must be
1010 in MSB first order in encoded format. They were encoded
1011 wrong and was in LSB format. Affected files are
1012 silcd/serverid.c, lib/silcutil/silcutil.c.
1014 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1016 * Call the `connect' client operation through the scheduler
1017 in case of error. Affected file lib/silcclient/client.c.
1019 * Call the `failure' client operation even if the error
1020 occurred locally during a protocol. Affected file is
1021 lib/silcclient/protocol.c.
1023 * Added support of sending LIST command to router from normal
1024 server. This way normal server can get list of all channels
1025 in the network too. Fixed the channel list sending in the
1026 server too. Affected files are silcd/command.c, and
1027 silcd/command_reply.[ch].
1029 * Added silc_server_update_channels_by_server and
1030 silc_server_remove_channels_by_server. They are used during
1031 disconnection of primary router and in backup router protocol.
1032 Affected file silcd/server_util.[ch], silcd/server.c and
1033 silcd/server_backup.c.
1035 * Fixed channel adding to global list in IDENTIFY command
1036 reply in server. Affected file silcd/command_reply.c.
1038 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1040 * If the incoming packet type is REKEY or REKEY_DONE process
1041 that packet always synchronously. Fixes yet another MAC
1042 failed error on slow (dialup) connections. Affected file
1043 lib/silcclient/client.c and silcd/server.c.
1045 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1047 * Call check_version SKE callback for initiator too. Affected
1048 file lib/silcske/silcske.c.
1050 * Implemented fix for security hole found in the SKE that was
1051 fixed in the specification few days back; the initiator's
1052 public key is now added to the HASH value computation.
1053 Added backwards support for the old way of doing it too, for
1054 old clients and old servers. Affected file is
1055 lib/silcske/silcske.c.
1057 * Enabled mutual authentication by default in SKE. If initiator
1058 is not providing mutual authentication the responder will
1059 force it. This will provide the proof of posession of the
1060 private key for responder. The affected files are
1061 lib/silcclient/protocol.c and silcd/protocol.c.
1063 * Do not cache anymore the server's public key during SKE.
1064 We do mutual authentication so the proof of posession of
1065 private key is done, and if the server is authenticated in
1066 conn auth protocol with public key we must have the public
1067 key already. Affected file silcd/protocol.c.
1069 * Added new global debug variable: silc_debug_hexdump. If
1070 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1071 file lib/silcutil/silclog.[ch].
1073 * Fixed compilation warning due to char * -> const char *.
1074 Affected files lib/silcutil/silcnet.h, and
1075 lib/silccore/silcauth.[ch].
1077 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1079 * Fixed CMODE command when new channel key was created. If
1080 the creation failed the old key was removed. Next time giving
1081 same command would crash the server since the old key was
1082 freed already. Affected file silcd/command.c.
1084 * Fixed the silc_server_announce_get_channels to not crash
1085 on reconnect. Affected file silcd/server.c.
1087 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1089 * Added silc_log_set_debug_string function to set a regex
1090 string to match for debug output. Only the function names,
1091 or filenames matching the given debug string is actually
1092 printed. This way it is possible to filter out those debug
1093 strings that user is not interested in.
1095 Fixed a bug in silc_string_regexify.
1097 Affected files lib/silcutil/silclog.[ch], and
1098 lib/silcutil/unix/silcunixutil.c.
1100 * Changed the -d options in both server and Irssi SILC client
1101 to take the debug string as argument. Affected files
1102 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1104 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1106 * Added silc_hash_babbleprint to create a Bubble Babble
1107 Encoded fingerprint. The encoding is developed by Antti
1108 Huima (draft-huima-babble-01.txt), and it creates human
1109 readable strings out of binary data. Affected file
1110 lib/silccrypt/silchash.[ch].
1112 * Print the babble print now in addition of fingerprint as well
1113 in Irssi SILC client. Affected files are

1117 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1119 * Fixed a security problem found in SKE. The initiator's
1120 public key too is now added to the HASH hash value creation
1121 which is signed by the responder to create the SIGN value.
1122 This will prevent anyone in the middle to lie to the responder
1123 about the initiator's public key. If this is done now, the
1124 man in the middle will get caught. Updated the protocol
1127 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1129 * Better installation directory handling. Configure module
1130 paths and other paths automatically to example_silc* files
1131 in doc/. A patch by toma.
1133 * Fixed compiler warning from MPI library, and from SILC RNG.
1136 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1137 It can be configured with ./configure. A patch by toma.
1139 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1141 * Find correct make to use in prepare-clean. A patch by
1142 toma. Affected file prepare-clean.

1163 * Added silc_pkcs_public_key_compare to compare two
1164 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1166 * Check that the client who set the founder mode on the
1167 channel is the same client that is giving the founder
1168 mode to itself. It is done by comparing the saved public
1169 key (it is saved even in the authentication is passphrase).

1177 * Process the DISCONNECT packet through scheduler in the
1178 client library. Affected file lib/silcclient/client.c.
1180 * Fixed the silc_client_packet_parse to not to increase
1181 the packet sequence number if the conn->sock and the
1182 current socket connection is not same. This can happen
1183 for example during key agreement when the conn includes
1184 multiple socket connections (listeners). Affected file
1185 lib/silcclient/client.c.
1187 * The sender of the file transfer request now provides also
1188 the pointer (listener) for the key exchange protocol. If
1189 the listener cannot be created then it sends empty key
1190 agreement and lets the receiver provide the listener.
1192 Added `local_ip' and `local_port' arguments to the
1193 silc_client_file_send. If they are provided they are used,
1194 if not then it will attempt to find local IP address, if
1195 not found or bind fails then the remote client will provide
1198 Affected files are lib/silcclient/client_ftp.c and
1199 lib/silcclient/silcapi.h.
1201 * Extended the FILE SEND command to support defining the
1202 local IP and port for key exchange listener. They are

1207 * Defined to WHOIS command reply the sending of fingerprint
1208 of the client's public key (if the proof of posession of the
1209 corresponding private key is verified by the server).
1210 Updated to the protocol specification.
1212 * Added support of receiving the client's public key's
1213 fingerprint in command reply in client library. Affected
1214 file is lib/silcclient/command_reply.c, and
1215 lib/silcclient/idlist.[ch].
1217 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1270 client library. Affected file lib/silcclient/client_prvmsg.c.
1272 * Do not actually remove the client directly from ID cache
1273 during SERVER_SIGNOFF, but invalidate it. This way we
1274 preserve the WHOWAS info for the client. Affected file
1275 silcd/server_util.c.
1277 * Fixed SERVER_SIGNOFF notify handling in the server. The
1278 server is now able to process incoming SERVER_SIGNOFF notify
1279 for a server that it doesn't even know about. It will remove
1280 the clients provided in the notify. Affected file
1281 silcd/packet_receive.c.
1283 * Check for partial packet in data queue after every packet that
1284 was found from the queue. Return and wait for more data if
1285 there is partial data in queue. Affected file is
1286 lib/silccore/silcpacket.c.
1288 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1290 * Added SilcClietFileError enum to indicate error in
1291 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT

1296 * Check that newsize in silc_buffer_realloc is larger than
1297 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1299 * Added better monitor of file transfers. It now monitors
1300 key agreement protocol during the file transfer too. Added
1301 error reporting too. Affected files
1302 irssi/src/silc/core/silc-servers.c,
1303 irssi/src/fe-common/silc/module-formats.[ch].
1305 * Wrote a help file for FILE command.
1307 * Added silc_rng_global_get_byte_fast to get not-so-secure
1308 random data as fast as possible. Random data is read from
1309 /dev/urandom if available and from the SILC RNG if not
1310 available. It is used in padding generation. Affected file
1311 lib/silccrypt/silcrng.[ch].
1313 * All packets in client library are now processed synchronously.
1314 Optimized packet processing a lot. Affected file
1315 lib/silcclient/client.c.
1317 * All server connection packets are processing synchronously
1318 now in server, to optimize packet processing. Affected file
1321 * Include files are installed now only in Toolkit distribution
1322 if make install is given. Affected files: all Makefile.am's.
1324 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1326 * Assure that silc_client_notify_by_server_resolve does not
1327 resolve the client information multiple times. If it cannot
1328 be found by the first it cannot be found at all. Affected
1329 file lib/silcclient/client_notify.c.
1331 * Fixed WHOWAS command reply calling. Affected file
1332 lib/silcclient/command_reply.c.
1334 * Removed all references to silc_idlist_get_client from the
1335 Irssi SILC client since that call is internal call used by
1336 the library. The Irssi SILC client will use now client
1337 retrieval functions found in silcapi.h.
1339 * Fixed a bug in resolving nickname info before sending
1340 private message. It used freed memory. Affected file
1341 irssi/src/silc/core/silc-servers.c.
1343 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1345 * Assure my_channels statistics cannot go negative in server.
1346 Affected files silcd/server.c, silcd/server_util.c.

1362 * Added silc_net_localip to return local host's IP address.
1363 Affected file lib/silcutil/silcnet.[ch].
1365 * If key exchange or rekey protocol is active for a connection
1366 parse all packets syncronously since there might be packets
1367 in packet queue that we are not able to process without first
1368 processing packets before them. Affected file silcd/server,
1369 lib/silcclient/client.c.
1371 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1372 whether library should continue processing the packet.
1373 Affected file lib/silccore/silcpacket.h.
1375 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

1419 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1420 is incomplete and is being resolved, it won't be resolved
1423 Make sure also that USERS command reply does not resolve
1424 twice information. Affected file is
1425 lib/silcclient/command_reply.c.
1427 Make sure that silc_client_get_clients_by_list does not
1428 resolve twice same information.
1430 * Check for valid client->id in the silc_server_free_client_data.
1431 Affected file silcd/server.c.
1433 * Fixed /GETKEY nick@server not to crash if the server entry
1434 is not found. Affected file lib/silcclient/command.c.
1436 * Fixed the silc_server_check_cmode_rights to check the
1437 requested modes correctly. Affected file silcd/command.c.

1444 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1446 * Call the silc_server_udpate_servers_by_server in the
1447 primary router that comes back online in the backup resuming
1448 protocol. Otherwise it routes packets wrong. Affected file
1449 silcd/server_util.[ch], silcd/server_backup.c.
1451 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1453 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1454 lib/silcutil/silcbuffmt.[ch].
1456 * Redefined the SILC packet header to include the padding
1457 length. Affected file lib/silccore/silcpacket.[ch].
1459 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1460 length for maximum padding up to 128 bytes). Affected
1461 file lib/silccore/silcpacket.h.
1463 * Removed all backwards support for old 0.5.x MAC thingies.
1464 The SILC packet header change makes it impossible to be
1465 backwards compatible.
1467 * Send the ENDING packet with timeout in the backup resuming
1468 protocol. This is to assure that all routers has connected
1469 to the primary router. Affected file silcd/server_backup.c.
1471 * Changed the RNG to take the first IV from random data. It
1472 used to take it from zero actually. Changed the RNG also
1473 to use /dev/urandom during session. /dev/random is used
1474 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1476 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1478 * Changed the SILC packet header to have the first two bytes
1479 (the packet length) encrypted. Affected files aroung the
1480 code tree, lib/silccore/silcpacket.[ch]. Removed the
1481 SilcPacketCheckDecrypt callback. It is not needed anymore
1482 since the silc_packet_receive_process will determine now
1483 whether the packet is normal or special.
1485 * Implemented the unidirectional MAC keys. Affected files
1486 lib/silcske/silcske.c, silcd/protocol.c and
1487 lib/silcclient/protocol.c.

1494 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1496 * Allow backup router to announce servers. All servers
1497 announced by backup router are added to the global list
1498 automatically. Update hte server's socket to our primary
1499 router also when backup router announces a server.
1500 Affected file silcd/packet_receive.c.
1502 * Do not update the client->router in the function
1503 silc_server_udpate_clients_by_server if the client is on
1504 global list. We might fail to find any specific server
1505 for locally connected clients and local cell clients. They
1506 should still use the `from' and not `to' as client->router.
1507 This fixes backup router resuming protocol. Affected file
1508 silcd/server_util.c.
1510 * Decrease channel statistics count only if the channel
1511 deletion worked. Affected files are silcd/server.c and
1512 silcd/server_util.c.
1514 * Added silc_server_update_servers_by_server to update origin
1515 of all server entries. Used during backup router protocol.

1524 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1526 * Assure that router cannot reroute the same channel message
1527 to the sender. Affected file silcd/packet_receive.c.
1529 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1531 * Made better checks that the channel message is not sent
1532 to the router it came from. Affected file is
1533 silcd/packet_send.c. Fixed memory leak too.
1535 * Announce informations for incoming router connection, but
1536 only after checking if it is replaced by backup router.
1537 Affected file silcd/packet_receive.c.
1539 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1541 * Fixed the backup resuming protocol to work in multiple
1542 router environment. Affected file silcd/server_backup.c.
1544 * Route packet only to one router in the function
1545 silc_server_packet_send_to_channel. Affected file is
1546 silcd/packet_send.c.
1548 * Fixed silc_server_send_notify_dest to set the broadcast
1549 flag. Fixed the silc_server_send_notify_topic to actually
1550 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1551 Affected file silcd/packet_send.c.
1553 * Changed the SFTP Filesystem interface. Changed the
1554 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1555 the filesystem operation function. The SilcSFTPFilesystem
1556 is now a context that is allocated by all filesystem allocation
1557 functions and it already includes the operations structure
1558 and filesystem specific context. It is given as argument
1559 now to the silc_sftp_server_start. This made the interface
1560 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1561 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1563 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1565 * Changed the backup router adding and getting interfaces
1566 in the server. The router that will be replaced by the
1567 specified backup router is now sent as argument. Affected
1568 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1571 * Added silc_net_addr2bin_ne to return the binary form of
1572 the IP address in network byte order. Affected files
1573 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1575 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1577 * Check for existing server ID in silc_server_new_server
1578 and in silc_server_connect_to_router_final and remove the
1579 old entry if it exists. Affected file silcd/packet_receive.c,
1582 * Send the channel message always to only one router, either
1583 in upstream or downstream. Affected file is
1584 silcd/packet_send.c.
1586 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1588 * Wrote the definition of the backup resuming protocol to the
1589 protocol specification.
1591 * Removed one redundant channel key generation from normal
1592 server during joining procedure. Removed one redundant
1593 channel key sending from server to router during joining
1594 procedure. Affected file silcd/command.c.
1596 * Made minor bugfixes to the backup router resuming protocol.
1597 Affected file silcd/server_backup.c, server.c.

1606 resume the primary router position in the cell after the
1607 primary router comes back online. Affected files
1608 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1609 and silcd/server_util.[ch].
1611 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1613 * Sleep two (2) seconds after sending QUIT command to server.
1614 Affected file lib/silcclient/command.c.
1616 * Assure that if outgoing data buffer is pending do not force
1617 send any data. Affected file silcd/packet_send.c.
1619 * Assure that if outgoing data buffer is pending do not force
1620 send any data. Affected file lib/silcclient/client.c.
1622 * Implemented the backup router support when the primary router
1623 goes down. The servers and routers can now use the backup
1624 router as new primary router without loosing connectivity.
1626 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1628 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1629 in the server to indicate disabled entry. All data read
1630 from the connection will be ignored and no data is sent
1631 for entry that is disabled. Affected files are
1632 silcd/idlist.h, silcd/server.c.
1634 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1636 * Created SFTP client and server test programs in the
1637 lib/silcsftp/tests directory.
1639 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1641 * Implemented memory filesystem (virtual filesystem) for
1642 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1645 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1647 * Implemented the SFTP (SSH File Transfer Protocol) to the
1648 lib/silcsftp. It includes SFTP client and SFTP server
1651 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1653 * Moved lib/silccore/silcprotocol.[ch] to the
1654 lib/silcutil library.
1656 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1657 take variable argument list pointer as argument. Affected
1658 file lib/silcutil/silcbuffmt.[ch].
1660 * Added silc_buffer_set function that is used to set data
1661 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1662 Affected file lib/silcutil/silcbuffer.h.
1664 * Changed various routines in the core library to use the new
1665 silc_buffer_set instead of allocating new buffer only for
1668 * Added 64-bit value formatting and unformatting support to the
1669 silc_buffer_[un]format routines. Affected file is
1670 lib/silcutil/silcbuffmt.[ch].
1672 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1673 to includes/bitmove.h.
1675 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1677 * Fixed channel user mode saving in client library. Affected
1678 file lib/silcclient/command[_reply].c.
1680 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1682 * Defined the file transfer to the SILC Protocol. Added
1683 new packet type SILC_PACKET_FTP and defined File Transfer
1684 Payload. The mandatory file transfer protocol is SFTP
1685 (SSH File Transfer Protocol). Affected file in addition
1686 of the internet draft is lib/silccore/silcpacket.h.
1688 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1689 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1690 is used as part of backup router protocol when the primary
1691 router of the cell is back online and wishes to resume
1692 the position as primary router.
1694 * Redefined the MAC generation keys in the protocol. The
1695 same key is not used anymore in both direction. Both
1696 direction will now use different keys for sending and
1697 receiving. This fixes a potential security flaw. This
1698 change causes incompatibilities in the protocol.
1700 * Redefined also the MAC computation from the packet.
1701 An packet sequence number is now added to the MAC
1702 computation. This prevents possible replay attacks against
1703 the protocol. This change too causes incompatibilities
1706 Added `sequence' field to the SilcPacketContext to hold
1707 the current sequence number for the packet.
1709 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1711 * Added `created' field to the SilcIDListData in the file
1712 silcd/idlist.h to indicate the time when the entry was
1715 * Added `created' field to the SilcChannelEntry too. Affected
1716 file silcd/idlist.h.
1718 * Added `creation_time' aguments to all the announcement functions
1719 in the server. If it is provided then only the entries that
1720 was created after the provided time frame are actually
1721 announced. Affected file silcd/server.[ch].
1723 * The protocol says that the Channel ID's IP address must be
1724 based on the router's IP address. Added check for this in
1725 the silc_server_new_channel when processing incoming New Channel
1726 Payload. Affected file silcd/packet_receive.c.
1728 * Print out the correct version with --version in SILC client.
1729 Affected file irssi/src/silc/core/silc-core.c.
1731 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1733 * Fixed WHOWAS command to check for completnes of the client
1734 entry always, not just when the command is coming from client.
1735 Affected file silcd/command.c.
1737 * Added new function silc_server_packet_queue_purge to purge the
1738 outgoing data queue to the network. After the function returns
1739 it is guaranteed that the outgoing packet queue is empty.
1740 Affected file silcd/packet_send.[ch].
1742 * Purge the outgoing packet queue in the rekey protocol's final
1743 callback to assure that all rekey packets go to the network
1744 before quitting the protocol. Affected file silcd/server.c.
1746 * Added silc_client_packet_queue_parse as similar function as
1747 in server to the client library. The affected file is
1748 lib/silcclient/client.c.
1750 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1752 * Splitted silcd/server.c and created silcd/server_util.[ch]
1753 for utility functions.
1755 * Added new socket flag SILC_SF_DISABLED to indicate that the
1756 connection is open but nothing can be sent to or received from
1757 the connection. Affected file lib/silcutil/silsockconn.[ch].
1758 The checking for disabled socket is checked in the low level
1759 silc_socket_write and silc_socket_read functions.
1761 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1763 * Allow only nicknames and channel names that fits into the
1764 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1766 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1768 * When processing JOIN command reply in server check that if
1769 the channel exists in our global list we'll move it the local
1770 list. Affected file silcd/command_reply.c.
1772 * Fixed the check whether client is joined on the channel already
1773 in JOIN command. Affected file lib/silcclient/command.c.
1775 * Fixed the JOIN command reply to check whether the channel
1776 already exists. Affected file lib/silcclient/command_reply.c.
1778 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1780 * Added silc_ske_status_string to map the SKE error numbers
1781 to readable strings. The affected files are
1782 lib/silcske/silcske[_status].[ch].
1784 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1786 * Do not show the private channels on the WHOIS channel list
1787 as it is not allowed by the protocol. The affected file is
1790 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1792 * Assure that the packet length digged from the actual packet
1793 is something sensible in the silc_packet_decrypt_rest_special
1794 in lib/silccrypt/silcpacket.c.
1796 * Free and NULL the allocated pointer in silc_hmac_alloc if
1797 the HMAC allocation fails. The affected file is
1798 lib/silccrypt/silchmac.c.
1800 * Print the selected security properties to the log files in
1801 the server. Affected file silcd/protocol.c.
1803 * Add SKE's reference counter even if calling the completion
1804 callback manually. Otherwise it goes negative, although it
1805 does not cause any problems. The affected file is
1806 lib/silcske/silcske.c.
1808 * Remove the client entry with short timeout after giving the
1809 KILL command. Affected file lib/silcclient/command.c.
1811 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1812 case all found clients are already disconnected (WHOWAS would
1813 found them) in the server. Affected file silcd/command.c.
1815 * Update the last_receive (time of last data received) to be
1816 updated only when received private or channel message so that
1817 the idle time showed in WHOIS makes more sense.
1819 * Added boolean field `valid' in to the SilcClientEntry in the
1820 client library to indicate whether the entry is valid or not.
1821 This fixes the nickname change bug on channel when changing
1822 the nickname to be same than the old (like nick to Nick) the
1823 nickname formatter doesn't set the new nick anymore to Nick@host.
1824 Affected file lib/silcclient/idlist.[ch].
1826 * Now actually fixed the nickname changing on disconnection.
1827 Added new function silc_change_nick to the Irssi SILC Client.
1828 Affected file irssi/src/silc/core/client_ops.c,
1829 irssi/src/silc/core/silc-nicklist.[ch].
1831 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1833 * Check that the public key exists in the GETKEY command before
1834 trying to encode it. Affected file silcd/command.c.
1836 * Print some notifications on received public keys with GETKEY
1837 command in the Irssi SILC Client. Affected files are
1838 irssi/src/fe-common/silc/module-formats.[ch],
1839 irssi/src/silc/core/client_ops.c.
1841 * Use IDENTIFY command to resolve the server information in the
1842 GETKEY command instead of INFO command. Affected file
1843 lib/silcclient/command.c.
1845 * All command reply functions in the client library now calls
1846 the pending command reply callbacks even if an error has
1847 occurred. The server has done this a long time and now it was
1848 time to move the client library to this as well. Now all
1849 errors can be delivered back to the pending command reply
1850 callbacks if necessary. Affected files are
1851 lib/silcclient/command[_reply].[ch].
1853 * Change the nickname on disconnection back to the username
1854 because in reconnect the server will enforce it to it anyway.
1855 Affected file irssi/src/silc/core/silc-servers.c.
1857 * Fixed a config file parsing bug in the Irssi SILC client.
1858 Affected file irssi/src/silc/core/clientconfig.c.
1860 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1862 * When printing the channel mode on JOIN, verify that the
1863 channel key and channel's HMAC are valid. Affected file
1864 irssi/src/silc/core/client_ops.c.
1866 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1868 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1869 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1870 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1872 * Removed channel key rekey task deleting from the function
1873 silc_server_save_channel_key. Affected file silcd/server.c.
1874 Added explicit timeout task context instead that is used to
1875 delete the task if we are registering a new task before the
1876 new task has elapsed.
1878 * When channel key rekey occurs the client library now saves
1879 the old channel key for a short period of time (10 seconds) and
1880 is able to use it in case some is still sending channel
1881 messages encrypted with the old key after the rekey. Affected
1882 file lib/silcclient/[idlist.h|client_channel.c].
1884 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1886 * Added check to the silc_server_new_id_real to not accept
1887 new ID if it is the sender's own ID. Affected file is
1888 silcd/packet_receive.c.
1890 * Assure that we do not announce ourself or the one we've
1891 sending our announcements when we're router and are announcing
1892 servers to our primary router. Affected file silcd/server.c.
1894 * Fixed silc_server_command_identify_check_client to assemble
1895 correct WHOIS packet. It send corrupted WHOIS packet and
1896 caused problem with router to router connections. Affected
1897 file silcd/command.c.
1899 Fixed also silc_server_command_whois_check the same way
1900 as for the IDENTIFY command.
1902 * Added new SilcIDListStatus to the server in the SilcIDListData
1903 structure. The status now includes the current status of
1904 the entry (like registered, resolved etc.). Affected file
1905 silcd/idlist.[ch]. Defined a bunch of different status types
1906 as well. This replaced the old boolean registered field as well.
1908 Added resolve_cmd_ident field to the SilcClientEntry structure
1909 too so that if the entry is for example being resolved so
1910 another command may attach to the same pending command reply
1911 without requiring to resolve the same entry again. This concept
1912 should optimize the WHOIS and the IDENTIFY resolving under
1913 heavy load by taking away unnecessary resolving for entries
1914 that are being resolved already.
1916 Added support for adding multiple pending commands for one
1917 command idenfier. Affected file silcd/command[_reply].[ch].
1919 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1920 before deleting the data. Otherwise the hash table will have
1921 freed data in comparison functions. Affected file is
1922 silcd/command_reply.c.
1924 * Fixed silc_idlist_replace_client_id to add the new entry to
1925 the cache with NULL nickname. Otherwise there will be invalid
1926 memory as the nickname after the nickname is freed. Affected
1927 file silcd/packet_receive.c.
1929 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1930 saved into wrong slots because the previous number of entries
1931 was not taken into account. Affected file silcd/idlist.c.
1932 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1934 * If we are router and we receive JOIN notify to a channel that
1935 does not have any users then notified client is marked as the
1936 channel founder, as it is it. The affected file is
1937 silcd/packet_receive.c
1939 * Added to the extended hash table API's table_del_*ext functions
1940 the destructor as argument too, so that the caller can decide
1941 which destructor to use or whether to use destructor at all.
1942 Affected file lib/silcutil/silchashtable.[ch].
1944 * Fixed ID Cache purging. It actually deleted the entries from
1945 the hash table after the data was freed. The hash table ended
1946 up comparing freed memory. The affected file is
1947 lib/silccore/silcidcache.c.
1949 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1951 * Fixed Irssi SILC client's KILL command's HELP syntax.
1953 * The USERS command now resolves the detailed user information
1954 if the userinfo field is missing. Affected file is
1955 lib/silcclient/command_reply.c.
1957 * Do not print error in silc_file_read if the read file does
1958 not exist. Just silently return NULL. Affected file is
1959 lib/silcutil/silcutil.c.
1961 * Fixed the silc_log_output to not wine about NULL filename
1962 and to not create some bogus " " filename. Affected file is
1963 lib/silcutil/silclog.c.
1965 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1967 * Fixed various printing bugs on the user interface in the
1968 Irssi SILC Client. Minor changes that were forgotten from
1971 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * Fixed the configure.in.pre and the compilation and distribution
1974 environment to support the new autoconf 2.52. That version is
1975 now required to compile the CVS trunk.
1977 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1979 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1980 to generally parse user@fqdn format strings. Affected file
1981 lib/silcutil/silcutil.c.
1983 * Added nickname_format and nickname_force_format fields to the
1984 SilcClientParams structure. The first one defines the format
1985 for the nicknames that the library will enforce if the receives
1986 multiple same nicknames. The second one is boolean value and
1987 can be used to force the library to always enforce the format
1988 to the nicknames regardles whether there are multiple nicknames
1989 or not. This configurable formatting was employed to flexibly
1990 support accessing multiple nicknames from the user interface.
1991 The userinterface can now set the nicknames to what ever format
1992 they prefer. Affected file lib/silcclient/silcapi.h.
1994 Added function silc_client_nickname_format to the file
1995 lib/silcclient/idlist.c. It performs the nickname formatting.
1997 Added new field `hostname´ to the SilcClientEntry context.
1998 It holds the hostname of the client. Affected file is
1999 lib/silcclient/idlist.h.
2001 * Irssi SILC Client sets the nicknames in nick@hostn format.
2002 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2003 irssi/src/silc/core/silc-core.c.
2005 The WHOIS printing now also shows both the real nickname and
2006 the formatted nickname so that user knows how to access the
2007 user if there are multiple same nicknames cached. Affected
2008 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2009 printing formatting too to take the hostname now as a separate
2010 argument. The Affected file is
2011 irssi/src/fe-common/silc/modules-formats.[ch].
2013 * Changed the silc_client_get_clients_local to accept the formatted
2014 nickname as argument. It accepts the real nickname too but the
2015 formatted nickname can be used to find the true entry from
2016 multiple entries. Affected file lib/silcclient/silcapi.h and
2017 lib/silcclient/idlist.c.
2019 * Added nickname_format_parse field to the SilcClientParams.
2020 It is a callback function provided by the application to parse
2021 the nickname out of the formatted nickname string. The library
2022 calls it to get the nickname from the formatted string. Since
2023 the application generally knows better the format of the nickname
2024 string it parses it instead of the library, even though library
2025 encodes the formatted string. If the callback function is not
2026 provided then the library will use the string as is. The
2027 affected file is lib/silcclient/silcapi.h.
2029 * All the nickname strings passed to the client library in
2030 commands are now expected to be formatted nickname strings.
2031 If the command does not support the formatted nickname string
2032 it will assume that the sent string is the actual nickname.
2033 Affected file lib/silcclient/command.c.
2035 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2037 * Added public key authentication support to OPER and SILCOPER
2038 commands in the client library. Affected file is
2039 lib/silcclient/command.c.
2041 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2043 * Changed the get_auth_methdod client operation to be asynchronous.
2044 It can be async if the application resolves the authentication
2045 method from the server during the negotiation. Added new
2046 SilcGetAuthMeth completion callback that the application will
2047 call after resolving the authentication method.
2049 Added function silc_client_request_authentication_method that
2050 the application can use to resolve the authentication method
2051 from the server. Added also SilcConnectionAuthRequest callback
2052 that the library will call after the server has replied. The
2053 application can call this function if it does not know the
2054 current authentication method.
2056 Affected files are lib/silcclient/client.c and
2057 lib/silcclient/silcapi.h.
2059 * The Irssi SILC client now automatically resolves the authentication
2060 method incase any configuration information is not present (and
2061 currently there never is). The affected file is
2062 irssi/src/silc/core/client_ops.c.
2064 * Fixed public key authentication from the client library.
2065 Affected file lib/silcclient/protocol.c. Changed also the
2066 protocol specification about the public key authentication in
2067 the connection authentication protocol. The actual data to be
2068 signed is now computed with a hash function before signing.
2070 * Fixed the public key authentication from the server as well.
2071 Affected file silcd/protocol.c.
2073 * Removed the mlock()'s from the memory allocation routines.
2074 Affected file lib/silcutil/silcmemory.c. The ./configure does
2075 not check anymore for the mlock(). Affected file is
2078 * Fixed USERS command in server to allow the execution of the
2079 command for private and secret channels if the client sending
2080 the command is on the channel. Affected file silcd/command.c.
2082 * Fixed silc_client_get_clients_local to return the clients
2083 count correctly. It could return wrong value. Affected file
2084 lib/silcclient/idlist.c.
2086 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2088 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2089 types. The assembler optimizations seemed not to like 64-bit
2090 data types. The assmebler optimizations thus are now enabled
2091 also for BSD systems as opposed to only enable them for Linux.
2093 * Do not check for threads at all on BSD systems. Affected
2094 file configure.in.pre.
2096 * Removed -n and -h options from the Irssi SILC Client since
2097 they are not used in silc.
2099 * Fixed the prime generation to assure that the first digit
2100 of the generated random number is not zero since our conversion
2101 routines does not like number strings that starts with zero
2102 digit. If zero digit is seen the random number is regenerated.
2103 This caused some corrupted RSA keys when the zero first digit
2104 was met. Affected file lib/silcmath/silcprimegen.c.
2106 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2108 * Fixed WIN32 configuration in the ./configure script.
2109 Fixed to include xti.h on environments that has it.
2110 Patches by Carsten Ilchmann and andrew.
2112 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2114 * Changed the silc_id_create_client_id to be collision
2115 resistant. It is now assured that there cannot be created
2116 two same client ID's. I suspect that some weird bugs in
2117 the server were actually caused by duplicate Client IDs.
2118 Affected file silcd/serverid.[ch]. A router receiving
2119 new ID now also assures and informs the sending server
2120 if the ID caused collision.
2122 * Changed the silc_id_create_channel_id to also assure that
2123 there are no collisions.
2125 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2127 * Statement about ignoring the Mutual Authentication flag when
2128 performing rekey with PFS was a bit misleading. It is ignored
2129 if it was set in the initial negotiation, it cannot be even
2130 set in the rekey. Fixed in the ke-auth draft. Started the
2131 new versions of the protocol drafts in the doc/.
2133 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2135 * Fixed a bug in silc_client_command_identify_save when saving
2136 new channel information. The channel name was no duplicated
2137 and caused crash on exit. Affected file is
2138 lib/silcclient/command_reply.c.
2140 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2142 * Fixed the getkey command handling in the server. Send just
2143 empty OK reply to the sender if the key could not be fetched
2144 (but everything else was ok, like the key just was not available).
2145 Changed the public key parameter to optional in the protocol
2146 specs so that empty OK reply can be sent. Affected file
2149 Added a message to Irssi SILC client to tell to user if the
2150 server did not return a public key.
2152 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2154 * Fixed a channel key regeneration bug. It registered new
2155 timeout tasks exponentially until all system resources were
2156 used. Affected file silcd/server.c.
2158 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2160 * Added the SILC Document generator to the scripts/silcdoc.
2161 It can be used to generate the Toolkit Reference Manual out
2162 of the source tree. Internally it will also use the RoboDoc
2163 generator now imported in util/robodoc.
2165 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2167 * Added couple of return's in rekey protocol if error orccurred
2168 during the protocol. The execution must be terminated.
2169 Affected file silcd/protocol.c. Also, terminate the protocol
2170 always with timeout.
2172 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2174 * The client's Client ID was created initally from the wrong
2175 nickname (it could have been in format nick@host) in the
2176 silc_server_new_client. Affected file silcd/packet_receive.c
2178 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2180 * Added some SILC_LOG_ERROR's to various error conditions
2181 if client could not be added to ID cache. Affected files
2182 silcd/packet_receive.c and silcd/server.c.
2184 * When client's sock->user_data is freed, NULL also the
2185 client->router and client->connection pointers. Added check
2186 for these pointers being NULL to various places around the
2187 code. Affected file silcd/server.c.
2189 * Added client->data.registered == TRUE checks to various
2190 places around the code to assure that unregistered client's
2191 are not handled when it is not allowed. Affected file
2194 * Added `bool registered' fields to all
2195 silc_idlist_[server|client]_get_* routines to indicate whether
2196 the fetched client needs to be registered or not. Affected
2197 file silcd/idlist.[ch].
2199 * Add your own entry as registered to the ID cache in the
2200 server. Affected file server.c.
2202 * Fixed a bug in silc_server_new_server. The SilcServer was
2203 set as the new server's context instead of SilcServerEntry.
2204 This naturally caused some weird bugs.
2206 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2208 * Do not delete the channel rekey task when adding it
2209 for in silc_server_create_channel_key.
2211 * Changed the silc_server_create_channel_key to return
2212 TRUE or FALSE to indicate the success of the channel key
2215 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2217 * Fixed MSVC++ project files and added missing files to

2223 does not have it defined. Affected files are
2224 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2226 * Fixed buffer overflow from Irssi SILC Client. Affected
2227 file irssi/src/fe-common/core/themes.c.
2229 * Fixed double free in client library in the file
2230 lib/silcclient/client.c when disconnecting from server.
2232 * Applied double free patch from cras to Irssi SILC client.
2233 Affected files irssi/src/core/[modules/expandos].c
2235 * Fixed the disconnection handling to Irssi SILC Client.
2236 The application must call silc_client_close_connection
2237 in ops->connect client operation in case of failure of
2238 the connection. Affected file is
2239 irssi/src/silc/core/client_ops.c.
2241 * Do not set sock->protocol to NULL in the function
2242 silc_client_close_connection after executing the protocol's
2243 final callback since the sock might not be valid anymore.
2244 Affected file lib/silcclient/client.c.
2246 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2248 * Do not enable SILC_THREADS if the linking with libpthread
2249 did not happen. Affected file configure.in.pre.
2251 * Added notion to protocol specification that server must
2252 verify the sent authentication payload with CMODE when
2253 setting the channel founder key. Implemented it to the
2254 server. Affected file silcd/command.c.
2256 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2258 * Added _EXTRA_DIST SILC distribution variable to the
2259 distributions file. It is used to conditionally add extra
2260 files or directories to the specific distribution. Affected
2261 files ./prepare, Makefile.am.pre and distributions.
2263 Removed the `_' from the start of the distribution names.
2266 * Added README.WIN32 for instructions to compile the Toolkit
2269 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2271 * Fixed a double free in disconnection in the server. Affected
2272 file is silcd/server.c.
2274 * Fixed the lib/silcske/groups.c to work now also with GMP
2275 MP library. The string conversion did not work when using
2276 specific base and the base is indicated in the string as well.
2278 * Created win32/ directory which now includes MSVC++ specific
2279 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2280 It will appear only in the toolkit distribution
2282 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2284 * Changed the key material distribution function in case when
2285 the hash output is too short. The data is now concatenated
2286 a bit differently than it used to. Made the change to the
2287 SKE protocol specification.
2289 * Added better GMP detection to configure.in.pre. A patch
2292 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2294 * Fixed a minor bug in SKE that might cause some problem on
2295 some platforms. Affected file lib/silcske/silcske.c.
2297 * Added the cookie checking for initiator in the SKE. It checks
2298 that the responder returns the sent cookie unmodified. The
2299 affected file is lib/silcske/silcske.c. Added new SKE
2300 error type INVALID_COOKIE that can be sent during the
2301 negotiation. Fixed some memory leaks as well.
2303 * Added the "invalid cookie" error message to Irssi SILC client's
2306 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2308 * Added `task_max' field to the SilcClientParams to indicate
2309 the maximum tasks the scheduler can handle. If set to zero,
2310 default values are used. Affected file lib/silcclient/silcapi.h.
2312 * Fixed memory leaks in silc_client_close_connection. Affected
2313 file lib/silcclient/client.c.
2315 * Added silc_client_del_client_entry to client library to free
2316 all memory of given client entry. Affected file is
2317 lib/silcclient/idlist.[ch].
2319 * Added new functions silc_client_del_channel and
2320 silc_client_del_server to delete channel and server entries.
2321 Affected file lib/silcclient/[silcapi.h/idlist.c].
2323 * Removed silc_client_del_client_by_id from silcapi.h.
2325 * Fixed the INFO command to return the server's own info
2326 correctly when querying by Server ID. Affected file is
2329 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2331 * Removed the non-blocking settings in WIN32 code in the
2332 silc_sock_[read/write] and added SleepEx instead. Affected
2333 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2334 of input data is now checked with FIONREAD and ioctlsocket.
2336 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2338 * Call silc_schedule_task_del_by_context in the
2339 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2340 Affected file lib/silccore/silcprotocol.c.
2342 * Call silc_protocol_cancel for active protocols in the
2343 silc_server_close_connection if the funtion
2344 silc_server_free_sock_user_data has not been called.
2345 Affected file silcd/server.c.
2347 * Generic tasks cannot be deleted using the del_by_fd
2348 task deleting function since generic tasks does not match
2349 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2351 * Added a notion to SILCOPER help file that the SILCOPER works
2352 only on router server, not on normal server.
2354 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2356 * Added for WIN32 support for the new scheduler as well.
2357 Affected file lib/silcutil/win32/silcwin32schedule.c.
2359 * Fixed the SHA1 implementation to work on various platforms.
2361 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2363 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2364 API. It is part of the scheduler now. Everything else is
2365 as previously but some functions has changed their names.
2366 Checkout the lib/silcutil/silcschedule.h for the interface.
2367 Updated all applications to use the new interface. Affected
2368 files are lib/silcutil/silcschedule.[ch].
2370 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2372 * Found a bug in the SKE implementation. The HASH value,
2373 specified by the protocol, was not computed correctly. The
2374 public key of the responder was not added to the computation
2375 even though it is mandatory. Affected file lib/silcske/silcske.c.
2376 This unfortunately causes incompatibilities with older
2377 clients and servers.
2379 * Added WIN32 specific network init and uninit functions:
2380 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2381 the Winsock2. Affected file lib/silcutil/silcnet.h and
2382 lib/silcutil/win32/silcwin32net.c.
2384 * Set the socket always to nonblocking mode on WIN32 after
2385 reading data or writing data. Affected file is
2386 lib/silcutil/win32/silcwin32sockconn.c.
2388 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2390 * Fixed various compilation problems under WIN32. Affected
2391 files lib/silcutil/win32/silcwin32thread.c and
2392 lib/silcutil/win32/silcwin32schedule.c.
2394 * Removed all _internal.h #includes from public header
2395 files. Internal headers must never be included from
2398 Removed also the lib/silcske/payload_internal.h file.
2400 * All include files that may be needed (public and some others
2401 included by the public headers) by application developers are
2402 now copied to the ./includes directory. It does not copy any
2403 internal headers. Affected file Makefile.defines.pre and all
2404 Makefile.am's under lib/ and subdirs.
2406 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2408 * Do not change the ~/.silc directory's permissions automatically.
2409 Affected file irssi/src/silc/core/clientutil.c.
2411 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2413 * Do not cancel the protocol in silc_server_close_connection
2414 it might cause recursion. Now cancelled in the function
2415 silc_server_free_sock_user_data. Affected file silcd/server.c.
2417 * Fixed the silc_server_remove_clients_by_server to regenerate
2418 the channel keys correctly finally. Added also new function
2419 silc_server_remove_clients_channels to actually do it.
2420 Affected file silcd/server.c.
2422 * Fixed the silc_server_new_channel to not crash by giving
2423 wrong router to the new channel. Affected file is
2424 silcd/packet_receive.c.
2426 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2428 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2429 which is given as argument to the silc_client_alloc now.
2430 It can be used to configure the client and set various parameters
2431 that affect the function of the client.
2433 * The USERS command in server did not check whether the channel
2434 is private or secret. Affected file silcd/command.c.
2436 * Added new argument to the USERS command in protocol specification.
2437 The USERS command now can take the channel name as argument
2438 as well. Added support for this in client and server and
2439 updated the protocol specs.
2441 * Completed the GETKEY command in client. It can be now used
2442 to fetch also servers public key not only some clients.
2443 Affected files lib/silcclient/command[_reply].c.
2445 * Added silc_client_get_server to return server entry by the
2446 server name. Affected files lib/silcclient/silcapi.h and
2449 * Redefined the IDENTIFY command in protocol specification to be
2450 more generic. It now can be used to query information about
2451 any entity in the SILC Network, including clients, servers and
2452 channels. The query may be based either the entity's name
2453 or the ID. Added support for this in both client and server.
2455 Affected files silcd/command.c and lib/silcclient/command.c
2456 and command_reply.c.
2458 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2459 the _from_client and _from_server functions. Affected file
2462 * Added silc_client_get_channel_by_id_resolve to the file
2463 lib/silcclient/silcapi.h to resolve channel information by
2464 its ID. Added also silc_client_get_channel_by_id that
2465 does not resolve it from the server.
2467 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2469 * Added SilcServerEntry context into the client library
2470 to represent one server. The INFO command now allocates
2471 these to save the resolved server info. For now on the
2472 client library will also keep information about servers,
2473 connected and resolved with INFO.
2475 The INFO command now allocates the SilcServerEntry context
2476 and saves the server info there. The COMMAND_REPLY in
2477 the INFO now returns the parameters to application in
2478 same order as defined in the protocol specification.
2480 The entries are cached in the client->server_cache.
2482 * The INFO command is now issued after received the Client ID
2483 from the server. Affected file lib/silcclient/client.c.
2485 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2486 to the application as the mode changer might be server.
2487 It is guaranteed that NULL is not returned anymore to the
2488 application. Affected file lib/silcclient/client_notify.c.
2490 The ID Type is now also passed to the application so that
2491 it can check whether the returned entry is SilcClientEntry
2494 Added new function silc_client_get_server_by_id to return
2495 the server entry by ID. Affected files are the
2496 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2498 * Do not create the channel in the Irssi SILC Client when issuing
2499 the JOIN command but when received the sucessful JOIN command
2500 reply. Otherwise the channel might get created even though we
2501 could not join it. The Affected file is
2502 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2504 * Fixed a channel joining bug in router. The router must also
2505 check the channel modes, invite and ban lists etc. when serving
2506 the JOIN command sent by normal server. Affected file is
2507 silcd/command.c. The router now resolves the client's
2508 information from the server who sent the JOIN command if it
2509 does not know it, and processes the JOIN command only after
2512 * Changed the SilcCommandCb to take new argument; void *context2.
2513 Affected file lib/silccore/silccommand.h
2515 The second argument in the command callbacks in the server now
2516 includes the SilcServerCommandReplyContext if the command was
2517 called as pending command callback from the command reply.
2518 Otherwise it is NULL. When called as pending the status of the
2519 command reply will be checked and if it was erronous the
2520 error will be sent to the original sender of the command.
2521 This way the client always receives the error messages even
2522 though the server was actually the one who received the error
2523 when it resent the command to router, for example. Affected
2524 files silcd/command[_reply].[ch].
2526 * Fixed sending WHOWAS command's error message to client if
2527 the requested client could not be found. It was missing.
2530 * Changed the CMODE and CUMODE commands reply arguments in the
2531 protocol specification. The Channel ID is now sent in both
2532 of the commands to identify the channel. Implemented this
2533 new feature to the client and server. Affected files
2534 lib/silcclient/command_reply.c and silcd/command.c.
2536 * Made better checks for invite and ban lists in the JOIN
2537 command in server. Affected file silcd/command.c.
2539 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2541 * The server now performs the incoming host IP/DNS lookup
2542 using the silc_socket_host_lookup and thus does not block
2543 the server anymore. Affected file silcd/server.c.
2545 * Completed the multi-thread support for SILC Scheduler in
2546 the lib/silcutil/silcschedule.c.
2548 * Fixed the configure.in.pre to detect the pthread correctly
2551 * Fixed a deadlock in silc_task_queue_wakeup in the file
2552 lib/silcutil/silctask.c.
2554 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2556 * Added new function silc_schedule_wakeup that is used in
2557 multi-threaded environment to wakeup the main thread's
2558 schduler. It needs to be used when a thread adds a new task
2559 or removes a task from task queues. After waking up, the
2560 scheduler will detect the task queue changes. If threads
2561 support is not compiled in this function has no effect.
2562 Implemented the wakeup mechanism to both Unix and WIN32
2563 systems. Affected files are lib/silcutil/silcschedule.[ch],
2564 lib/silcutil/unix/silcunixschedule.c and the
2565 lib/silcutil/win32/silcwin32schedule.c.
2567 * Added new function silc_task_queue_wakeup to wakeup the
2568 scheduler by the specified task queue. Affected file
2569 lib/silcutil/silctask.[ch].
2571 * The silc_socket_host_lookup_start now wakes up the scheduler
2572 after adding the timeout task. Affected file is
2573 lib/silcutil/silcsockconn.c.
2575 * The silc_socket_host_lookup is synchronous now if the threads
2576 support is not compiled in. However, the callback is still
2577 called asyncronously through the scheduler, anyway. Affected
2578 file lib/silcutil/silcsockconn.c.
2580 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2582 * Added new function silc_socket_host_lookup to perform
2583 asynchronous IP and FQDN lookups for the socket connection.
2584 Affected files lib/silcutil/silcsockconn.[ch].
2586 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2588 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2589 that may or may not compile the mutex support in.
2591 Changed the silc_mutex_alloc interface. It allocates the
2592 mutex now to the sent pointer and returns TRUE or FALSE.
2594 Affected file lib/silcutil/silcmutex.h.
2596 * Wrote the SILC Task Queue interface to support multi-threads.
2597 Affected file lib/silcutil/silctask.[ch].
2599 * Wrote the SILC Scheduler to support multi-threads. Affected
2600 file lib/silcutil/silcschedule.c.
2602 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2604 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2605 in lib/silcutil/win32/.
2607 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2609 * Defined SILC Mutex API and SILC Thread API and implemented
2610 them for Unix. Affected files are
2611 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2612 lib/silcutil/unix/silcunixmutex.c and
2613 lib/silcutil/unix/silcunixthread.c.
2615 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2617 * Fixed the silc_server_remove_clients_by_server's channel
2618 key re-generation. The hash table handling was incorrect
2619 and would not work with many channels. Affected file is
2622 * Fixed some memory leaks around the server code.
2624 * Rewrote the silc_server_get_users_on_channel to support IPv6
2625 based Client ID's. Affected file silcd/server.c.
2627 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2628 specification. However, a separate document must be written
2629 to define the detailed signing procedure and the payload
2630 associated with the flag. Defined the flag to the
2631 lib/silccore/silcchannel.h as well.
2633 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2635 * Changed the dynamic tables to static size tables in the
2636 lib/silccrypt/silchmac.c.
2638 * Removed GCC dependencies from the code. A patch by cras.
2640 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2642 * Do not show the error "Error receiving packet bla bla"
2643 in server if it really was not an error (-2 means that reading
2644 is pending). Affected file silcd/server.c.
2646 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2648 * Fixed a possible crash in silc_server_remove_clients_by_server
2649 in silcd/server.c. Fixed there also some memory leaks.
2651 * Fixed the silc_idlist_replace_client_id. It could replace
2652 wrong key in the hash table. Affected file silcd/idlist.c.
2654 * Do not check whether there are global users on the channel
2655 if the channel->global_users is FALSE. Affected functions
2656 silc_server_remove_from_one_channel and
2657 silc_server_remove_from_channels in silcd/server.c. Also,
2658 do not check if the removed client is local as we can be
2659 sure that global client was not removed from the channel
2660 and checking for global users is not needed.
2662 * The silc_server_remove_clients_by_server now re-generates
2663 the channel keys correctly for those channels that had
2664 clients removed from them. Affected file silcd/server.c.
2666 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2668 * Found the reason of random crashes in the server. We weren't
2669 ignoring the SIGPIPE signal (which can be sent in write())
2670 and it crashed the server. Affected file silcd/silcd.c.
2672 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2674 * Assure that sock->user_data is not NULL in the function
2675 silc_server_packet_send in silcd/packet_send.c.
2677 * Disconnect the remote connection if it could not be added
2678 to any ID lists in the server. The affected file is
2681 * Check in silc_server_packet_send[_real/dest] that the
2682 socket is not disconnecting and ignore the data if it is.
2683 Affected file silcd/packet_send.c.
2685 * Define inline to __inline on native WIN32 compilation.
2686 Affected file includes/silcwin32.h.
2688 * Added some explicit type casts for inline code since MSVC
2689 require them. Affected files lib/silcutil/silcbuffer.h,
2690 lib/trq/silcdlist.h and lib/trq/silclist.h.
2692 * Print warning in log files from now on if the packet
2693 decryption fails. Affected file silcd/server.c.
2695 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2697 * Changed the `say' client operation's interface to accept
2698 new `type' argument to indicate the type of the message sent
2699 by the library. The application may filter the library's
2700 messages according the type. The affected file is the
2701 lib/silcclient/silcapi.h.
2703 * Added two new functions to lib/silcclient/silcapi.h:
2704 silc_client_del_client and silc_client_del_client_by_id.
2705 Affected file lib/silcclient/idlist.c.
2707 * Moved the clientincludes.h from includes/ to silc/ and
2708 serverincludes.h from includes/ to silcd/.
2710 * The modes for the CMODE and CUMODE are now passed as
2711 uint32 for application with COMMAND_REPLY. The affected
2712 file is lib/silcclient/command_reply.c.
2714 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2716 * /WHOIS without arguments shows client's own information.
2717 Affected file lib/silcclient/command.c.
2719 * Changed PING to not accept any arguments. The specs
2720 says that client can ping only the connected server so
2721 requiring an argument is not needed. Affected file is
2722 lib/silcclient/command.c.
2724 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2726 * Fixed a fatal bug in private message sending and reception
2727 encryption and decryption when using private message keys.
2728 The implementation was incorrect and did not follow the
2729 specification. It causd that some of the message were
2730 lost since it did not use the sending and receiving keys
2731 as the protocol suggests. This has been fixed and will cause
2732 incompatibilities with older clients when sending private
2733 message encrypted with private message keys. Affected files
2734 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2735 and various other in Irssi SILC Client.
2737 Added `responder' boolean argument to the functions
2738 silc_client_add_private_message_key[_ske] to indicate when
2739 the key is added as responder or initiator of the key
2742 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2744 * Removed the silc_ske_check_version function and created
2745 a SilcSKECheckVersion callback. Added also a function
2746 silc_ske_set_callbacks that is now used to set all SKE
2747 callbacks. The callback functions are not given to
2748 the SKE functions anymore, but this function is used to
2751 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2753 * Added `silc_version' argument to the silc_client_alloc
2754 to define the version of the application for the library.
2755 The library will use the version string to compare it
2756 against the remote host's (usually a server) version
2757 string. Affected file lib/silcclient/silcapi.h
2759 * Added the KE protocol context to Key Agreement context
2760 in client library so that we can abort the SKE if it
2761 is in process when we get timeout. Affected file is
2762 lib/silcclient/client_keyagr.c.
2764 * Do not resolve the client ID forever if it returns in the
2765 first time that such client does not exist. This was done
2766 for example with private message. Affected file is
2767 lib/silcclient/client_prvmsg.c.
2769 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2771 * Do not add regex.h for WIN32. The affected file
2772 includes/silcincludes.h.
2774 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2775 not work yet 100%. It generates the DLL's automatically
2776 when compiling with --with-win32 under cygwin.
2778 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2780 * lib/contrib/regex.c is not compiled on WIN32.
2782 * Added silc_net_get_socket_opt function to the
2783 lib/silcutil/silcnet.h.
2785 * Added includes/silcwin32.h for WIN32 specific includes
2788 * Do not use ptime structure or any of the posix process
2789 functions on WIN32 in lib/silccrypt/silrng.c.
2791 * Added silc_gettimeofday to provide generic function
2792 for struct timeval on all platforms. Added the function
2793 to lib/silcutil/silcutil.h.
2795 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2797 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2798 library as they clearly belong there. As a plus side we
2799 can make the actual socket connection routines platform
2802 Added also new generic function silc_socket_read and
2803 silc_socket_write (that used to be silc_packet_[read/write].
2804 The implementation of these are platform specific.
2806 * Added WIN32 specific routines of silc_socket_[read/write]
2807 to lib/silcutil/win32/silcwin32sockconn.c.
2809 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2811 * Added preliminary support for native WIN32 compilation under
2812 cygwin (using the -mno-cygwin option for GCC) to the
2813 ./configure.in.pre. The --with-win32 now prepares the
2814 compilation for native WIN32.
2816 * Rewrote the SILC Scheduler interface in the file
2817 lib/silcutil/silcschedule.h. The scheduler is now context
2818 based and does not have anymore any global static scheduler.
2819 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2820 and created lib/silcutil/win32 directory for WIN32 based
2823 * Added Unix specific network routines to the
2824 lib/silcutil/unix/silcunixnet.c and the old
2825 lib/silcutil/silcnet.c includes now only generic routines.
2827 Added WIN32 specific network routines to the
2828 lib/silcutil/win32/silcwin32net.c.
2830 * Added Unix specific utility functions from the
2831 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2833 * Added WIN32 SILC Scheduler to the file
2834 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2837 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2839 * Do not handle JOIN notify in the server if the target client
2840 is not registered (idata->registered == FALSE). The affected
2841 file is silcd/packet_receive.c.
2843 * Update the nickrec->founder in event_cumode in the Irssi SILC
2844 client. Affected file irssi/src/silc/core/silc-channels.c.
2846 * Fixed the CUMODE_CHANGE notify handling in the server when
2847 server and router are announcing their clients on channels.
2848 Now the mode changes are saved and notified correctly. The
2849 affected file is /silcd/packet_receive.c.
2851 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2852 They really did not replace the cache entry in the ID Cache.
2853 Now they do that. Affected file silcd/idlist.c.
2855 * Fixed the KICK notify handling in the Irssi SILC client to
2856 update the channel records so that the kicked client does not
2857 appear to be on the channel. The affected file is
2858 irssi/src/silc/core/silc-channels.c.
2860 * Always update the conn->current_channel when executing command
2861 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2863 * Fixed the KILL notify handling in Irssi SILC client to remove
2864 the killed client on all channels.
2866 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2868 * Fixed the silc_parse_command_line to remove extra spaces
2869 from the start and end of the arguments. Affected file is
2870 lib/silcutil/silcutil.c.
2872 * Cancel and free any active protocol in the function
2873 silc_server_close_connection. Affected file silcd/server.c.
2875 * Cancel and free any active protocol in the function
2876 silc_client_close_connction. Affected file is
2877 lib/silcclient/client.c.
2879 * Do not execute the KILL command for clients that are in
2880 history (ie. they are not in the network). Affected file is
2883 * Fixed KILL notify handling, client does not crash anymore.
2884 Affected file irssi/src/silc/core/silc-channels.c.
2886 * Reduced the default packet buffer size from 2048 to 1024 in
2887 lib/silccore/silcpacket.c.
2889 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2890 counter to the SKE context that is incresed when the SKE library
2891 performs async operation outside the library. If the outside
2892 process frees the SKE context and FREED status will be set
2893 and the library will detect after the sync operation that the
2894 libary is freed. The affected files are
2895 lib/silcske/silcske[_status].[ch].
2897 * Resolve the client entry information in the function
2898 silc_client_channel_message to assure that NULL pointer is not
2899 passed as client entry to the application. */
2901 * Fixed the task timeout calculation to assure that there is
2902 never negative timeouts. The affected file is
2903 lib/silcutil/silcschedule.c.
2905 * Fixed the channel user mode notification sending in server.
2906 It was sent point-to-point to the router (or to server by router)
2907 but it needs to be destined to a channel. The routines now
2908 supports sending the channel user mode notifys to the channels
2909 when announcing clients and channels. Affected files are
2910 silcd/server.c and silcd/packet_receive.c.
2912 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2913 It did not actually replace the old channel entry in the cache.
2914 Affected file lib/silcclient/client_notify.c.
2916 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2918 * Fixed a possible crash in silc_packet_send_prepare. It now
2919 assures always that there is enough space in the buffer and
2920 at the tail area of the buffer (for MAC).
2922 Fixed the inbound buffer reallocation in silc_packet_read.
2923 It was old code and did not handle the reallocation correctly.
2926 The affected file is lib/silccore/silcpacket.c.
2928 * Fixed buffer overflow in silc_parse_nickname in the file
2929 lib/silcutil/silcutil.c.
2931 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2933 * make install generates new server keys only if there is not
2936 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2938 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2939 Added check that if the NOREPLY is set then we will not send
2940 the away message. This avoids infinite loop of away messages
2941 if both clients are away. The affected file is
2942 lib/silcclient/client_prvmsg.c.
2944 * Fixed client crash if /NICK was given without arguments.
2945 Affected file lib/silcclient/command.c.
2947 * Server does not send the invite list in INVITE command back
2948 to the client if the list was not altered. Added this notion
2949 to the protocol spec as well. Affected file silcd/command.c.
2951 Fixed possible crash in INVITE command by checking the
2952 value of silc_server_get_client_route command.
2954 * Fixed the INVITE notify type handling. The arguments are now
2955 taken in correct order and client does not crash. The affected
2956 file is irssi/src/silc/core/silc-channels.c.
2958 Removed the "Inviting xxx to channel" message from the
2959 client library away and let the application handle it.
2960 Affected file lib/silcclient/command.c. Added that message
2961 to Irssi SILC client's message formats.
2963 * Fixed CMODE command crash in client. It now checks the
2964 amount of arguments correctly and does not crash. The affected
2965 file is lib/silcclient/command.c.
2967 * Do not create new channel automatically in silc_channels_join
2968 but check whether the channel by that name already exists.
2969 Affected file irssi/silc/core/silc-channels.c.
2971 * Do not send the SERVER_SIGNOFF to router if the disconnected
2972 entity was the router. Affected file silcd/server.c.
2974 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2975 SILC client as it was missing from there.
2977 Added the handling of the KICK notify to the Irssi SILC client
2978 as it was missing. Added "you have been kicked" message to
2979 Irssi SILC client's message modules formats.
2981 Added the handing of the KILL notify to the Irssi SILC client
2982 as it was missing. Added the kill message module formats
2985 The affected file is irssi/src/silc/core/silc-channels.c.
2987 * The router did not save the channel mode the server announced.
2988 Affected file silcd/packet_receive.c.
2990 * Fixed a possible crash in INFO command in server. If the
2991 server did not provide the server info it crashed. Affected
2992 file silcd/command.c.
2994 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2996 * Fixed the GETKEY command in the server to check also the
2997 global list. Otherwise the GETKEY would not work correctly
2998 in normal SILC server. Affected file silcd/command.c.
3000 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3002 * Fixed GETKEY crash, it crashed if the command did not succseed.
3004 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3006 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3007 is now real and not just an macro interface to GMP.
3009 Removed the entire GMP from the source tree and imported new
3010 NSS MPI library instead. Reason for removing GMP is that it is
3011 extremely large and compiles extremely slow. The NSS MPI
3012 is only a few files and compiles in less than 10 seconds.
3013 The speed is also about the same as GMP. The MPI is imported
3014 to lib/silcmath/mpi.
3016 If the system has GMP installed we will still use the GMP.
3017 If it is not then the NSS MPI will be compiled.
3019 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3021 * Merged a long nickname (127 characters long) crash bugfix from
3022 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3024 * Merged a freed memory reference bugfix from Irssi CVS tree.
3025 Affected file irssi/src/core/commands.c.
3027 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3029 * Added the server's public key sving and verification to the
3030 server when performing the SKE. This was missing and the
3031 remote server's (or router's) public key was accepted without
3032 checking whether we have it previously or trust it at all.
3033 Affected file silcd/protocol.c.
3035 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3037 * Check in the silc_server_timeout_remote if protocol is active
3038 and make sure that the protocol's final callback is called so
3039 that all memory if freed. Affected file silcd/server.c.
3041 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3043 * silc_server_whois_send_reply crashed the server if the nickname
3044 was 127 characters long. Affected file silcd/command.c.
3046 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3048 * Added sanity check to the silc_server_new_client. If the hostname
3049 is provided inside username then check that the provided hostname
3050 really is the same as the resolved one. If the hostname was not
3051 resolved then check it from the public key. Affected file is
3052 silcd/packet_receive.c.
3054 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3055 if the server disconnected us and the connection is not valid
3056 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3058 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3059 the library to the lib/silcutil/silcutil.[ch].
3061 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3063 * Close log file after open. Affected file
3064 lib/silcutil/silclog.c.
3066 * Check whether sock == NULL in silc_client_send_packet and return
3067 if it is. Affected file lib/silcclient/silcclient.c.
3069 * Check rec->entry == NULL in the Irssi SILC Client before
3070 sending the channel message. Affecte file is
3071 irssi/src/silc/core/silc-servers.c.
3073 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3075 * Merged a splitted window bugfix from Irssi CVS tree. The
3076 affected file is irssi/src/fe-text/textbuffer-view.c.
3078 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3079 It did not print nickname.
3081 * Improved the distributions system a bit.
3083 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3085 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3086 irssi/src/fe-text/gui-window.c.
3088 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3089 to in-active server. The affected file is
3090 irssi/src/silc/core/client_ops.c.
3092 * Resolve the client in USERS command reply if the entry does
3093 not have username resolved. The affected file is
3094 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3095 command to WHOIS command to really resolve stuff. The USERS
3096 is not used any more in any critical section so WHOIS can
3097 be used even though it might be slower than IDENTIFY.
3099 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3102 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3104 * Changed the protocol API a bit more consistent in the
3105 lib/silccore/silcprotocol.[ch].
3107 * Changed the following headers to ROBODoc format:
3109 lib/silccore/silcpayload.h
3110 lib/silccore/silcprotocol.h
3111 lib/silccore/silcsockconn.h
3113 All core library headers are now formatted.
3115 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3117 * Fixed a bug in Irssi SILC client; do not show that you are
3118 server/router operator if you really are not. Affected file is
3119 irssi/src/silc/core/client_ops.c.
3121 * Renamed silc_command_free_payload to silc_command_payload_free.
3122 Affected file lib/silccore/silccommand.h
3124 * Added silcmath.h to include the prototoypes of various routines
3125 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3128 * Changed the following headers to ROBODoc format:
3130 lib/silccore/silcchannel.h
3131 lib/silccore/silccommand.h
3132 lib/silccore/silcid.h
3133 lib/silccore/silcidcache.h
3134 lib/silccore/silcmode.h
3135 lib/silccore/silcnotify.h
3136 lib/silccore/silcpacket.h
3137 lib/silcmath/silcmath.h
3139 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3141 * Added checking to the server code not to start the server if
3142 ciphers and stuff are not configured properly. Affected files
3143 silcd/serverconfig.[h] and silcd/server.c.
3145 * Changed the layout of the header files of the public interfaces
3146 in the SILC libraries. The new layout supports ROBODoc
3147 documentation tool (and some others) so that it is easy to create
3148 a library reference manual. All the other headers and source
3149 code must still follow the CodingStyle document. Also source
3150 code must not include these ROBODoc stuffs, only the headers.
3151 Furthermore, all public interface headers must now be named
3152 by using `silc' prefix, example: silcapi.h, silccipher.h.
3153 Some files were renamed due to this. All the other headers
3154 must not be used as public interfaces. I will update the
3155 CodingStyle document later. Changed following headers, so far:
3157 lib/silcclient/silcapi.h
3158 lib/silccore/silcauth.h
3159 lib/silccore/silcprivate.h
3160 lib/silccrypt/silcdh.h
3162 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3166 * Removed silc_client_packet_send_flush from the client library
3167 as it is not needed. Affected file lib/silcclient/client.[ch].
3169 * Added printing of message of unresolved authentication method
3170 to the Irssi SILC client. Added it to the module formats.
3171 Removed the same message from the client library.
3173 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3175 * Added new distribution feature, DISTLABEL. Every distribution
3176 can define own preprocessor label that can be used in the
3177 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3178 file distributions, acconfig.h.pre and prepare.
3180 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3182 * Added Makefile.defines_int to include the actual definitions
3183 for Makefile.defines.in. Tested the new distribution system,
3184 created distributions and tested installation.
3186 * Added AWAY message printing to the Irssi SILC client. Added
3187 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3189 * Added SCONNECT command to call the SILC's CONNECT command.
3190 Cannot use CONNECT directly since Irssi uses that internally.
3191 Affected file irssi/src/silc/core/silc-servers.c.
3193 Added ACTION local command. It is same as ME command but takes
3194 the channel as mandatory argument.
3196 Rewrote some of the Irssi's help files to suite for SILC
3199 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3201 * Added Makefile.defines[.in] that should for now on be included
3202 in all Makefile.am file in the source tree. That file includes
3203 all common compilation definitions for SILC source tree.
3205 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3207 * Minor changes to the ./prepare script to change the package
3208 name according the distribution name to the configure.in.
3210 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3212 * Created new distribution system. Added file `distributions'
3213 that defines all the distributions that can be created out of
3214 the SILC source tree. The ./prepare script now reads that
3215 file to determine how to prepare the distributions. The
3216 first argument to the ./prepare is the name of the distribution
3217 and second is the version of the distribution. If given
3218 without arguments it creates the default (toolkit) distribution
3219 with the default version (defined in ./prepare).
3221 All Makefile.am files that are subject to the distributions
3222 are now named as Makefile.am.pre. These are ./Makefile.am
3223 and lib/Makefile.am. Others may be changed later.
3225 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3227 * Added invite list, ban list, some key management and connection
3228 error message printing to module formats in the Irssi SILC client.
3230 * Added new silc_client_set_away_message to set the away message
3231 that is back to the person who sent private message. The
3232 affected file lib/silcclient/silcapi.h and the
3233 lib/silcclient/client_prvmsg.c.
3235 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3237 * Fixed the private message sending in the Irssi SILC client,
3238 added local command KEY to the Irssi SILC client.
3240 Added key management and key agreement message formats to the
3241 irssi/src/fe-common/silc/module-formats.[ch].
3243 Added USERS (alias WHO) printing, server/router operator
3244 indication and LIST command printing to the module formats.
3246 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3248 * Fixed channel joining notify handling, cumode notify handling
3249 from Irssi SILC client.
3251 * Added SILC specific module-formats to the Irssi SILC client so
3252 that SILC specific message hilighting, colors etc is possible.
3253 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3255 Added channel mode, channel user mode, actions, notices,
3256 whois and whowas printing to the the module-formats.c.
3258 * Fixed a bug in channel deletion in the server. The channel
3259 is not left to the cache even if the channel founder auth mode
3260 is set when there are no users anymore on the channel. Affected
3261 file silcd/server.c.
3263 * The silc_net_localhost now resolves the entire hostname including
3264 the domain name. Affected file lib/silcutil/silcnet.c.
3266 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3268 * Changed the ask_passphrase client operation to be ascynchronous.
3269 It has now a completion callback and a context that the
3270 application must call after it has got the passphrase from
3271 the user. Affected files lib/silcclient/silcapi.h,
3272 lib/silcclient/protocol.c, lib/silcclient/command.c and
3275 Added SilcAskPassphrase callback that the application calls
3276 to deliver the passphrase to the library.
3278 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3279 The public key verification and especially a certificate
3280 verification is asynchronous procedure.
3282 Added new SILC_SKE_STATUS_PENDING status to indicate the
3283 request is pending and a callback will be called to finalize
3286 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3287 indicate that remote end did not send its public key (or
3288 certificate), even though we require it. Added check for this
3289 condition in the SKE. This was a security bug, now fixed.
3291 Defined new SilcSKEVerifyCbCompletion callback that is called
3292 when the verification process is completed.
3294 The affected files lib/silcske/silcske_status.h and
3295 lib/silcske/silcske.[ch].
3297 * Changed the verify_public_key client operation to be async
3298 as well. Defined SilcVerifyPublicKey callback that is used to
3299 indicate the success of the public key verification process.
3301 Changed the server and client to use the new async client
3304 * Changed the Irssi SILC client's internal scheduler to be called
3305 twice as many times as it used to be. As a result the client
3306 should be a bit faster now. Affected file is
3307 irssi/src/silc/core/silc-core.c.
3309 * Added support to Irssi SILC client of asynchronous public key
3310 verification and passphrase inquiry. Affected file is
3311 irssi/src/silc/core/silc-core.c.
3313 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3315 * Do not say "You have left channel %s" in client library.
3316 Moved it to the application. Affected files are
3317 lib/silcclient/command.c and silc/client_ops.c.
3319 * Fixed silc_client_get_clients. Command context was not
3320 duplicated and was freed memory in the callback. Affected
3321 file lib/silcclient/idlist.c.
3323 * Do not say "you are now talking..." on JOIN command in the
3324 client library. The appliation must handle it.
3326 * Do not say ".. changed topic to" in command reply in the
3327 client libary. The application must handle it.
3329 * Fixed TOPIC command sending in the client library.
3331 * Fixed a memory leak in silc_client_command_free in the file
3332 lib/silcclient/command.c.
3334 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3336 * Imported a modified version of Irssi client to the source tree.
3337 The Irssi will be used to create a new client called
3338 Irssi SILC. Imported to irssi/.
3340 Added silc_core_init_finish function to the Irssi. Affected
3341 file irssi/configure.in.
3343 A lot changes in the Makefile.ams around the irssi tree.
3345 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3347 * Do not rehash if the new size is same as the old size of the
3348 hash table, in the silc_hash_table_rehash*. The affected file
3349 lib/silcutil/silchashtable.c.
3351 * Replaced hash_table_del_by_context calls from the server
3352 (when channel->user_list and client->channels) to the
3353 hash_table_del as it is sufficient and faster.
3355 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3357 * Added silc_hash_table_list, silc_hash_table_get and the
3358 SilcHashTableList structure to provide an alternative way to
3359 traverse the hash table. The affected files are
3360 lib/silcutil/silchashtable.[ch].
3362 * Changed the server's idlist routines to use the hash table
3363 routines to optimize the code.
3365 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3367 * Replaced the client entry's `channel' list and channel entry's
3368 `user_list' list to hash tables for optimized lookup. Changed
3369 the code to use the hash table interface around the code.
3370 Affected file lib/silcd/idlist.[ch].
3372 * Added `auto_rehash' boolean argument to the function
3373 silc_hash_table_alloc to indicate whether the hash table should
3374 auto-rehash when it thinks is appropriate time. It will
3375 increase the hash table size if the there is twice as much
3376 entries in the table than the size of the table, and will
3377 decrease the size if there are twice as less entries than
3378 the size of the table.
3380 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3382 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3384 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3386 * silc_idcache_purge_by_context deletes the entry now by context
3387 as it is supposed to do. Affected file lib/silccore/idcache.c.
3389 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3390 client is not anymore valid (WHOWAS givens the info) and not
3391 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3393 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3395 * Removed the `data' and `data_len' arguments from the ID Cache
3396 interfaces and added `name' argument. ID Cache does not handle
3397 anymore the binary data only a names associated with given ID.
3399 * When hashing a Client ID with silc_hash_id the entire ID is
3400 not hashed anymore, instead only the hash of the Client ID is
3401 hashed. This way we can access the Client ID from the cache
3402 with Client ID but with the hash of the ID (which is a hash of
3403 the nickname) as well without any difference in performance.
3405 Added also silc_idcache_find_by_id_one_ext to do one on one
3406 searching when we have the actual ID. Added also function
3407 silc_hash_client_id_compare. The affected files are
3408 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3410 * When hashing the name associated with a ID it is always done
3411 in lowercase. This way we can access the cache without worrying
3412 about case-sensitivity, even though, for example nicknames are
3415 * Fixed a bug in server with channel message sending. It put
3416 wrong ID type as destination ID. The affected file
3417 silcd/packet_send.c.
3419 * silc_idcache_del_by_context now deletes from all hash tables
3420 by context. Affected file lib/silccore/idcache.c.
3422 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3424 * Changed the client library to use the new ID Cache interface.
3425 Changes around the source tree.
3427 * Added silc_hash_table_rehash_ext to rehash with specific
3428 hash function. Affected file lib/silcutil/silchashtable.[ch].
3430 * Added silc_hash_string_compare to compare two strings in the
3431 hash table. Affected file lib/silcutil/silcutil.[ch].
3433 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3435 * Added new function silc_idcache_del_by_context into the
3436 lib/silccore/idcache.[ch].
3438 * Changed the server's ID list routines to use the new ID Cache
3439 interface. Changes around the source tree.
3441 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3443 * Added silc_hash_table_del[_by_context]_ext functions in to the
3444 lib/silcutil/silchashtable.[ch].
3446 Removed silc_hash_table_find_all* routines and added new
3447 silc_hash_table_find_foreach to replace them.
3449 Added silc_hash_table_replace_ext function as extended
3450 replacing function. Separated the simple hash table interface
3451 from the extended hash table interface in the file
3452 lib/silcutil/silchashtable.h.
3454 * Fixed minor bugs and changed it to use some of the new
3455 hash table functions in lib/silccore/idcache.c
3457 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3459 * Added new function silc_hash_table_find_all to return all keys
3460 in the hash table by the specified key. As the hash table is
3461 collision resistant it also makes it possible to have several
3462 duplicate keys in the hash table. This function may be used to
3463 find all of the keys from the hash.
3465 Added user_context arguments to the SilcHashFunction,
3466 SilcHashCompare and SilcHashDestructor to deliver user specified
3469 Added new fuctions silc_hash_table_find[_all]_ext to do
3470 extended lookup with specified hash and compare functions and
3471 specified user contexts.
3473 Added new function silc_hash_table_add_ext to add the key
3474 with specified hash function and user context.
3476 Added new function silc_hash_table_foreach to traverse all
3477 entrys in the hash table. Added SilcHashForeach callback
3480 Added new function silc_hash_table_del_by_context to delete
3481 the entry only if the context associated with the key matches.
3483 Affected files are lib/silcutil/silchashtable.[ch].
3485 * Removed silc_hash_[server/client/channel]_id and added just
3486 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3487 silc_hash_id_compare to compare two ID's using as the hash table
3488 comparison function. Added also silc_hash_data to hash
3489 binary data and silc_hash_data_compare to compare it.
3491 * Removed silc_idlist_find_client_by_hash as it is not needed
3492 anymore. Affected file silcd/idlist.[ch].
3494 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3495 to use internally the SilcHashTable. The new ID Cache is a lot
3496 faster than the old one. Some of the ID Cache interface was also
3497 rewritten and obsolete and stupid functions were removed.
3499 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3501 * Added entry_count field to the SilcHashTable to keep the number
3502 of the entries in the table. Implemented the function
3503 silc_hash_table_rehash. Added new function
3504 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3506 Fixed a minor bug in silc_hash_table_free.
3508 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3509 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3510 into the lib/silcutil/silcutil.[ch].
3512 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3514 * Implemented a collision resistant hash table into the
3515 lib/silcutil/silchashtable[ch]. See the header and the source
3516 for the SilcHashTable API.
3518 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3520 * Merged dotconf version 1.0.2 into lib/dotconf.
3522 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Do not compile anything in lib/silcsim/* if the SIM support
3525 is not enabled. The tree should now compile without problems
3528 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3530 * Compiled the SILC under cygwin. Compiled and tested briefly
3531 without problems. More tests needed. The SIMs didn't compile
3534 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3536 * Fixed possible crash in silc_get_username in the
3537 lib/silcutil/silcutil.c.
3539 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3541 * Fixed a va_arg in silc/client_ops.c.
3543 * Oops, RC5 routines were named AES and caused some problems
3544 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3546 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3548 * Added new SilcIDIP structure into the lib/silccore/id.h and
3549 replaced the old `ip' fields from all SILC ID's to that type.
3550 This is a step towards IPv6 support.
3552 The silc_id_get_len takes now the ID as an extra argument.
3553 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3554 both IPv4 and IPv6 based ID's.
3556 The affected files are lib/silccore/id.[ch] and other files
3557 around the tree using these routines.
3559 * Removed the ID length arguments in server from various
3560 silc_server_send_notify_* routines -> they are not needed
3563 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3565 * Fixed memory leak in silc_encode_pem_file in the file
3566 lib/silcutil/silcutil.c.
3568 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3570 * Check minor version as well in the SKE. Affected files are
3571 silcd/protocol.c and lib/silcclient/protocol.c.
3573 * Added --identifier option to the server so that an identifier
3574 can be when creating the public key for the server. Affected
3575 file is silcd/silcd.c.
3577 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3578 lib/silccrypt/silcpkcs.c.
3580 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3582 * Register default ciphers and stuff when using -C option with
3583 the server. Affected file sildc/silcd.c.
3585 * Put back the servers public key filename format, it is better
3586 than the new one. For now, the client keys are saved with the
3587 new filename format. The affected file silc/client_ops.c.
3589 * Implemented the Cipher API for the rest of the ciphers that
3590 did not implement it or implemented it the wrong way.
3592 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3594 * Register default ciphers and stuff when using the -S option
3595 in the client. Affected file silc/silc.c. Same also when
3596 creating new key pair with -C option.
3598 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3600 * Fixed the silc_verify_public_key client operation function to
3601 save the public keys differently. The fingerprint is now
3602 used as filename and not the hostname. This way also the
3603 client keys are saved uniquely and not with hostnames. The
3604 affected file is silc/client_ops.c.
3606 * Trimmed the silc_hash_fingerprint function to remove extra
3607 whitespaces from the end of the fingerprint. The affected
3608 file is lib/silccrypt/silchash.c.
3612 * Added silc_cipher_register_default function to register all
3613 default ciphers. It can be used when configuration files
3614 does not exist and the application does not want any specific
3615 ciphers in any specific order.
3617 The SilcDList is now used as silc_cipher_list dynamically
3618 allocated cipher list. Removed the static list all together
3619 and now all ciphers must be allocated to the dynamic list.
3620 The silc_cipher_alloc routine was changed to check only the
3623 All silc_cipher_* routines that used to return int returns
3626 The affected files lib/silccrypt/silccrypt.[ch].
3628 * The same thing was done to silc_hash_* as for silc_cipher_*
3629 routines. Affected files lib/silccrypt/silchash.[ch].
3631 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3632 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3633 Added also silc_pkcs_[un]register[_default] functions.
3634 Removed the data_context from the PKCS API.
3636 * Added silc_hmac_register_default function to register default
3637 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3638 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3639 to unregister all hmacs at once.
3641 * Register the default ciphers, hash functions, PKCSs and HMACs
3642 if client's configuration file does not exist. The affected
3645 * The client did not load the hash functions from the SIM
3646 modules at all. Added support for this. Affected file is
3647 silc/clientconfig.c.
3649 * When decoding public key with silc_pkcs_public_key_decode, check
3650 the supported algorithm only if PKCS are registered. Affected
3651 file lib/silccrypt/silcpkcs.c. The same was done with the
3652 silc_pkcs_private_key_decode.
3654 * Fixed the SILC List routines to keep the list always in order.
3655 It used to change the list's order when traversing the list but
3656 not it preserves the order. Affected file lib/trq/silclist.h.
3658 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3660 * Added the client library to use the SilcSocketConnection's
3661 reference counter (by silc_socket_dup) to prevent the bug that
3662 the socket object may be freed underneath async operation.
3664 * The name resolv library checking fixes in the configure.in.pre.
3667 * Created new version of the protocol drafts for future
3668 development. The -03 drafts are the ones that will be changed
3669 in the trunk now and the -02 will remain as they are.
3671 * Send list of CUMODE notifys to the router when announcing
3672 the channel users to the router. Affected file silcd/server.c.
3673 If the router receiving channel founder CUMODE for a channel
3674 that already has channel founder it will send CUMODE notify
3675 to the sender to remove the channel founder rights from the
3676 announced client. Affected file silcd/packet_receive.c.
3678 * The CUMODE notify may now use Server ID as well as the entity
3679 who changes the mode. Updated protocool specs.
3681 * Updated INSTALL and README files.
3683 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3685 * New web pages in the http://silc.pspt.fi. The pages was
3690 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3692 * Implemented the [DenyConnectin] config section in the server.
3693 Added silc_server_config_denied_conn to check whether incoming
3694 connection is denied. Affected file silcd/serverconfig.[ch].
3696 * Do not check the ports when checking the incoming configuration
3697 data if the port is 0, meaning any. Affected file is
3698 silcd/serverconfig.c.
3700 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3702 * Fixed buffer overflow in silc_string_compare in the file
3703 lib/silcutil/silcutil.c.
3705 * Fixed double free in silc_server_command_leave in the file
3708 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3710 * Fixed the version checking in the server. Affected file is
3713 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3715 * Fixed the configuration data fetching when accepting new
3716 connections in the server. Affected file silcd/server.c.
3718 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Added `sender_entry' argument to the function
3721 silc_server_packet_relay_to_channel so that we can check
3722 whether some destination actually belongs to the same route
3723 the sender belongs (ie, we must not resend the packet to the
3724 sender). Affected file silcd/packet_send.[ch].
3726 * Added `servername' field to the SilcClientEntry in the server
3727 to hold the name of the server where client is from. Affected
3728 file is silcd/idlist.h.
3730 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3732 * Moved the channel message encrypting in the router betwen
3733 router connections from silc_server_channel_message to the
3734 silc_server_packet_relay_to_channel since we want to check
3735 whether we have anybody channel before encrypting anything.
3736 Affected files silcd/packet_[receive/send].c.
3738 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3740 * Fixed the [AdminConnection] server config section to support
3741 multiple entries. Affected file silcd/serverconfig.c.
3743 * Added support into the server to check the validity of the
3744 incoming connection before executing any KE or authentication
3747 * The connection configuration is now saved to the KE and
3748 connection auth protocol contexts and not fetched anymore in
3749 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3751 * The local hosts listenning address and port is also resolved
3752 now when starting the server. We want to have the socket object
3753 to include the real address and port for the listener. Added
3754 new function silc_net_check_local_by_sock into the files
3755 lib/silcutil/silcnet.[ch].
3757 * Fixed a broadcast bug in server -> do not broadcast if we
3760 * Fixed a routing bug. Do not route broadcast packets ever.
3761 Broadcast packets must be processed always and not routed since
3762 they may be destined to some other host than yourself and thus
3763 would get routed without no good reason. Affected file is
3766 * Added function silc_server_config_is_primary_route to check
3767 whether primary router connection has been configured (a router
3768 configuration that we are initiating). If there is not, we
3769 will assume that there is only two routers in the SILC network
3770 and we will use the incoming router connection as our primary
3771 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3773 * Changed the order of the broadcasting. Broadcast _after_ the
3774 packet has been processed not before. Affected file is
3777 * Fixed a [ClientConnection] parsing bug. The port was never
3778 parsed correctly thus resulting to port 0. Affected file
3779 silcd/serverconfig.c.
3781 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3782 argument and did not set the broadcast packet flag. Affected
3783 file silcd/packet_send.c. Fixed same bug in the function
3784 silc_server_send_notify as well.
3786 * If we receive NEW_ID packet for our own ID in the server, ignore
3789 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3793 * Removed the nickname from the Private Message Payload.
3794 Updated the code and the protocol specs.
3796 * Updated protocol specs for submitting to the IETF.
3798 * Tweaked the Random Number Generator a bit. Affected file
3799 lib/silccrypt/silcrng.c. Exported a new function
3800 silc_rng_[global]_add_noise which can be used to add more
3803 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Do not parse packets with different timeout when protocol
3806 is active -> may cause problem with rekey. Affected file
3809 * When server receives signoff notify it must not create
3810 new channel key if the client is on any channels since the
3811 sender of the signoff notify will create it.
3813 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Added printing of error messages during SKE protocol from the
3816 failure packet sent by server during SKE. Affected file
3819 * Removed the client's failure_callback handling with timeout
3820 and handle it immediately when received.
3822 * The SKE library returned wrong type in SUCCESS and FAILURE
3823 packets. They must be 32 bit MSB not 16 bit MSB.
3825 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3827 * Ok, rewrote the logic of the re-key and now it seems to work.
3828 I tested it on high traffic with frequent re-keys without
3829 problems. Added hmac_receive (and renamed hmac to hmac_send)
3830 in SilcClientConnection in lib/silcclient/client.h and
3831 in SilcIDListData in silcd/idlist.h. Also, removed the
3832 SilcPacketParserContext's cipher and hmac fields as they are
3833 not needed anymore and actually caused some problems when
3834 the ciphers and hmac's changed underneath the packet parser.
3836 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3838 * If re-key protocol is active then process the incoming packets
3839 synchronously since we must assure that icoming packets encrypted
3840 with the old key is processed before the new keys is set to
3841 use. This is true other packets than for REKEY packets.
3842 Affected file silcd/server.c. The same was done to client library
3843 as well, affected file lib/silcclient/client.c.
3845 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Fixed bug in client and server to accept the force send if
3848 the packet is send from silc_[server/client]_packet_process
3849 function. Otherwise the packets are never delivered, oops.
3851 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3853 * Disable force sending of packets when REKEY protocol is active.
3854 We must assure that no packet is sent directly when rekey is
3855 performed. All packets must be sent through packet queue.
3856 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3857 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3858 function is silc_[server/client]_packet_send_real to check
3861 * Replaced the SIM paths from example config files to
3862 /usr/local/modules. Also, make install creates now
3863 /usr/local/silc/logs directory to hold all the SILC server
3866 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3868 * Made the configure.in.pre work on Solaris. Patch by salo.
3870 * Made all ciphers compatible with non-x86 machines. Defined
3871 CBC mode macros into lib/silccrypt/ciphers_def.h.
3873 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3875 * Fixed the make install.
3877 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3879 * When MAC computation fails the silc_packet_decrypt returned 0
3880 even though it was supposed to return -1. Fixed this. The
3881 affected file is lib/silccore/silcpacket.c.
3883 * Do not replace the config files in /etc/silc (in make install)
3884 if they already exist. Affected file ./Makefile.am.
3886 * Do not send re-key packets immediately but through packet queue.
3887 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3889 * Changed silc_net_check_host_by_sock to return FALSE if the
3890 IP/DNS could not be resolved. Though, it returns the IP address
3891 now even if it could not resolve it (but returns also FALSE).
3892 Affected file lib/silcutil/silcnet.[ch].
3894 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3896 * Added silc_pkcs_decode_identifier to decode the public key's
3897 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3898 Added also silc_pkcs_free_identifier. Added also new context
3899 SilcPublicKeyIdentifier.
3901 * Added -S option to the silc client. It is used to dump the
3902 contents of the specified public key file.
3904 * Changed the PKCS api to return the public key length when
3905 setting the public key.
3907 * Fixed a fatal bug in the public and private key file loading.
3908 Affected file lib/silccrypt/silcpkcs.c.
3910 * Execute the packet parsing for client with zero (0) timeout
3911 if the protocol is active. Affected file silcd/server.c.
3913 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3915 * Made the key generation options to the silcd program. Added
3916 -C option, equivalent to client's option.
3918 * Added new [ServerKeys] config section to the server. It
3919 configures the server's public and private key.
3921 * Defined generic Public Key Payload into the protocol
3922 specification to send specific type of public keys and
3925 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3926 public key or certificate.
3928 * Implemented the GETKEY command to the server and to the
3929 client library and on user interface.
3931 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3933 * Made preliminary `make install' work.
3935 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3937 * Added SilcServerRekey context into silcd/idlist.h.
3939 * Added the PFS support as defined in the specification to the
3940 SKE protocol. Affected files lib/silcske/*.c.
3942 * Added `ske_group' field to the SilcServerRekey context to hold
3943 the number of the SKE group that is used with PFS in re-key.
3944 Affected file silcd/idlist.h.
3946 * Added PFS re-key support to the server. Affected file is
3949 * Added silc_protocol_cancel to cancel execution of the next
3950 state of the protocol. Affected file is
3951 lib/silccore/silcprotocol.[ch].
3953 * Added the re-key support with and without PFS to the client
3954 library. Re-key is performed once in an hour, by default.
3956 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3957 Added silc_client_rekey_callback and silc_client_rekey_final.
3958 Affected files are lib/silcclient/protocol.[ch] and
3959 lib/silcclient/client.[ch].
3961 * Removed the `hmac_key' and `hmac_key_len' fields from the
3962 SilcClientConnection structure; not needed. Affected file is
3963 lib/silcclient/client.h.
3967 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3969 * Do not ask whether user wants to use the negotiated private key
3970 for private messages, just use it. Affected file is
3971 silc/local_command.c.
3973 * Added `send_enc_key' and `enc_key_len' fields to the
3974 SilcIDListData structure since they are needed in the re-key
3975 phase. Affected file is silcd/idlist.[ch].
3977 * Implemented the simple re-key protocol into the server.
3978 Affected files silcd/server.c and silcd/protocol.[ch]. The
3979 re-key will be performed once in an hour, by default.
3981 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3982 Added silc_server_rekey, silc_server_rekey_callback and
3983 silc_server_rekey_final.
3985 * Removed Tunneled flag from the protocol. Updated the code
3986 and the specifications.
3988 * Adde `pfs' field to the SilcIDListData to indicate whether
3989 the PFS is to be performed in the re-key. Affected file is
3992 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3994 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3995 int64 of at least the xintXX size. If void * is less that 4
3996 bytes uint32 * will be used. Defined bool as boolean.
3998 * Changed _ALL_ unsigned long and unsigned int to uint32,
3999 unsgined short to uint16 in the source tree.
4001 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4002 not handle clients that has entry->data.registered == FALSE.
4003 They are not in the network anymore. Affected file is
4006 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4008 * Implemented the sending of the SERVER_SIGNOFF notify in the
4009 server. Affected file is silcd/server.c.
4011 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4012 Added also silc_notify_payload_encode_args into the
4013 lib/silccore/silcnotify.[ch].
4015 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4016 Affected file silcd/packet_receive.c.
4018 * Implemented the SERVER_SIGNOFF notify handling in the client
4019 library. Affected file lib/silcclient/client_notify.c. Also,
4020 implemnted the printing of the SERVER_SIGNOFF info to the
4021 application. Affected file silc/client_ops.c.
4023 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4024 if the deleting was successful. Affected file silcd/idlist.[ch].
4026 * Added support for public key authentication in the connection
4027 authentication protocol in the client library. Affected file
4028 lib/silcclient/protocol.c.
4030 * Changed the server's silc_idlist_get_clients_by_* interface
4031 to support already allocated array so that new entries may be
4032 added to pre-allocated array. Affected file silcd/idlist.[ch].
4033 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4034 and command replies.
4036 * All command reply functions in the server now calls the
4037 pending command callback even if error occured. This way the
4038 error will be delivered to the client as well. Affected files
4039 silcd/command.c and silcd/command_reply.c.
4041 * Fixed INFO command to return local server's info if no server
4042 was provided. Affected file lib/silcclient/command.c.
4044 * Removed RESTART command for good. Updated the code and the
4047 * Rewrote parts of the task system. It is a bit simpler now.
4048 Removed unsued task priorities. The affected files are
4049 lib/silcutil/silctask.[ch].
4051 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4053 * Moved the USERS printing from the library to the application.
4054 Affected files lib/silcclient/command.c and silc/client_ops.c.
4056 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4060 * Added channel key re-key support. The re-key is perfomed
4061 only by the router and is done once in an hour. Added `rekey'
4062 field to the SilcChannelEntry in the server. Affected files
4063 silcd/server.c and silcd/idlist.h.
4065 * Added silc_task_unregister_by_context into the file
4066 lib/silcutil/silctask.[ch].
4068 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4070 * Added SILC_UMODE_GONE mode to indicate when the client is not
4071 present in the SILC network. Added also support to the local
4072 command AWAY that will set this mode. Added support of showing
4073 "xxx is gone" in WHOIS command. The USERS command shows the
4074 gone status as well.
4076 * Fixed setting server and router operator privileges in the
4077 server's UMODE command. Affected file silcd/command.c.
4079 * Merged the SKE KE1 and KE2 payloads into one payload. The
4080 new KE payload is equivalent to the old KE2 payload.
4082 Cleaned up the SKE Start Payload parsing. It now uses the
4083 simple buffer unformatting to do the parsing. A lot faster
4086 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4087 to the SKE that is used to indicate whether both of the SKE
4088 parties should perform authentication. By default only the
4089 responder performs authentication. By setting this flag also
4090 the initiator must do authentication. By default it is unset
4091 since in normal SKE case, client to server connection, only
4092 the responder should do authentication. When doing SKE between
4093 two clients both should perform authentication. Updated the
4094 code and the protocol specs.
4096 * A little fix to IDENTIFY command in the server. Search the
4097 client first by hash not nickname. Affected file is
4100 * Fixed the silc_client_close_connection to support closing
4101 the client to client connections wihtout deleting too much
4102 data. Affected file lib/silcclient/client.c.
4104 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4105 are received if protocol used to be active but is not anymore
4106 the application would crash due to NULL pointer dereference.
4107 Affected files silcd/server.c and lib/silcclient/client.c.
4109 * Added `hash' field to the SilcClientConnection to include
4110 the hash function negotiated in the SKE protocol.
4112 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4113 to set the channel founder authentication data. A client can
4114 claim the founder rights later by providing the authentication
4115 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4116 This way the channel founder can regain the channel founder
4117 privileges even it is left the channel. This works only on
4118 local server and the client must be connected to the same
4119 server to be able to regain the founder rights. Updated the
4120 protocol specs accordingly.
4122 Added support to the CMODE command in the client to set the
4123 founder auth data. Read the README to see how to set it.
4125 Added support to the CUMODE command to claim the founder
4126 rights. Read the README to see how to do it.
4128 Added support for the founder authentication to the Channel
4129 Entry in the server. Affected file silcd/idlist.h.
4131 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4132 server's CMODE command. Affected file silcd/command.c.
4134 * Added the following new functions into lib/silccore/silcauth.[ch]:
4135 silc_auth_get_method and silc_auth_get_data.
4137 * The server now saves the remote hosts public key to the
4138 SilcIDListData pointer. Affected file silcd/protocol.c.
4140 * The normal server now does not remove the channel entry from
4141 the cache if the founder authentication data is set. It used
4142 to remove it if the founder was the last one on the channel on
4143 the server and left the channel. The auth data is saved and
4144 if the channel is re-joined later the old entry is used with
4145 the old auth data. Affected files silcd/command_reply.c and
4148 * Removed the `pkcs' field from the SilcIDListData structure
4149 in the server; it is not used. Affected file silcd/idlist.h.
4151 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4153 * Fixed packet processing on slow links. Partial packets were
4154 never re-processed because the incoming data buffer was cleared
4155 by the application. Application must not directly clear the
4156 sock->inbuf, the packet processing routines handle it. Fixed
4157 this in client library and in server.
4159 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4161 * Fixed the WHOIS and IDENTIFY send reply function to really
4162 check whether to send list or just one entry. Affected file
4165 * Cleaned up the LEAVE command's channel key distribution. The
4166 affected file silcd/command.c.
4168 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4169 can enforce the channel mode as well. In that case the ID
4170 includes the ID of the server. The code now enforces the
4171 mode change if the router have different mode than the server.
4173 * The notify client operation with CMODE_CHANGE notify can now
4174 return NULL client_entry pointer if the CMODE was not changed
4175 by client. Application must check for this.
4177 * Added <Server ID> argument to INFO command to support server
4178 info fetching by Server ID.
4180 * Added silc_server_announce_get_channel_users to get assembled
4181 packets of channel users of the specified channel. Affected
4182 file silcd/server.[ch].
4184 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4185 was freed underneath the ID Cache.
4187 * Re-announce clients when the server received CHANNEL_CHANGE
4188 notify from the router. Affected file silcd/packet_send.c.
4190 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4192 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4193 crashed since it did not handle the fact that there is no cipher
4194 called "3" and didn't check the error condition. Now fixed.
4196 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4197 flag. It can be used to send message requests.
4199 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4201 * Implemented the RESTART command in the client.
4203 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4204 notice type messages. Added notice printing to the user
4207 * The channel keys are not re-generated if the channel's mode
4208 is PRIVKEY, ie private key on the channel exists. Affected
4209 files silcd/server.c and silcd/command.c.
4211 * Fixed a little bug in channel message delivery when channel
4212 private keys are set in the server. Affected file is
4213 silcd/packet_send.c.
4215 * Changed the setting on channel->on_channel = TRUE from the
4216 silc_client_save_channel_key to the JOIN command reply. The
4217 key payload is not received if the private channel key is set.
4218 Affected file lib/silcclient/command_reply.c and the
4219 lib/silcclient/client_channel.c.
4221 * When the CMODE_CHANGE notify is sent and the channel private
4222 key mode is removed the channel key must be re-generated in
4223 other cells as well. Added this support for the router in the
4224 silcd/packet_receive.c.
4226 * Added new local command NOTICE to send notice message on
4227 channel. Affected file silc/local_command.[ch].
4229 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4231 * Added new local command ME to the client. It is used to send
4232 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4233 some action. Affected file silc/local_command.[ch].
4235 * Changed channel_message and private_message client operations
4236 to deliver the message flags to the application. Added also
4237 the `flags' arguments to the silc_client_send_channel_message
4238 and silc_client_send_private_message functions. Affected file
4241 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4243 * Redefined the Private Message Payload to support private message
4244 keys and to support the new private message flags. Updated
4245 the protocol specs. Flags makes it possible to have for example
4246 CTCP style messages.
4248 * Added new type SilcPrivateMessagePayload and defined an API
4249 for it in the lib/silcclient/silcprivate.[ch].
4251 * Tested private message private keys successfully. Tested the
4252 private message key set, unset and list commands with the new
4255 * Redefined the Channel Message Payload to include the channel
4256 message flags (equal with private message flags) to support
4257 for example CTCP style messages.
4259 * Defined some of the message (for channel and private message)
4260 flags. Updated the protocol specs and added the flags to the
4261 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4263 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4265 * Added SilcKeyAgreementStatus type to the key agreement routines
4266 to indicate the current status and error if one occured.
4267 The status types are defined in the lib/silcclient/silcapi.h.
4269 * Added new local command KEY that is used to set and unset private
4270 keys for channels, set and unset private keys for private messages
4271 with remote clients and to send key agreement requests and
4272 negotiate the key agreement protocol with remote client. The
4273 key agreement is supported only to negotiate private message keys,
4274 it currently cannot be used to negotiate private keys for channels,
4275 as it is not convenient for that purpose.
4277 * Fixed a minor pending callback setting bug in the function
4278 silc_client_get_client_by_id_resolve, now the function works.
4279 Affected file lib/silcclient/idlist.c.
4281 * Added function silc_net_get_local_port to get local bound
4282 port by socket. Added to lib/silcutil/silcnet.[ch].
4284 * Added `sockets' and `sockets_count' fields to the SilcClient
4285 object. They hold the sockets of the listenning sockets in
4286 the client. Listenning sockets may be for example the key
4287 agreement server. Affected file lib/silcclient/client.[ch].
4288 Added functions the silc_client_add_socket and the
4289 silc_client_del_socket. They are exported to the application
4292 * Added ~./silc/clientkeys to support other client's public keys.
4294 * Renamed verify_server_key client operation to verify_public_key
4295 and added one argument to indicate the type of the connection
4296 (server, client etc.).
4298 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4300 * Added silc_server_connection_auth_request to handle the
4301 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4302 silcd/packet_receive.[ch].
4304 * Added silc_server_send_connection_auth_request into the
4305 silcd/packet_send.c to send the connection auth request packet.
4307 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4310 * Fixed the public key authentication in responder side in the
4311 server. The `auth_data' pointer includes the SilcPublicKey
4312 not the path to the public key. Affected file silcd/protocol.c.
4314 * Implemented the public key authentication in the initiator side
4315 in the server. Affected file silcd/protocol.c.
4317 * Removed the [RedirectClient] config section from the server
4318 configuration. Is not needed and I don't want to implement it.
4320 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Cleaned up the CMODE command in the server. It now works
4323 correctly and supports all the modes defined in the protocol.
4324 Affected file is silcd/command.c.
4326 * Added `hmac_name' field to the SilcChannelEntry in the server
4327 to hold the default HMAC of the channel. It can be set when
4328 creating the channel (with JOIN command). Affected files
4331 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4332 type to indicate the change of the current cipher and hmac
4333 on the channel. Client can safely ignore the <cipher> argument
4334 (if it chooses to do so) since the CHANNEL_KEY packet will
4335 force the channel key change anyway. The <hmac> argument is
4336 important since the client is responsible of setting the new
4337 HMAC and the hmac key into use.
4339 * Fixed the CMODE command in the client library as well.
4341 * Tested CMODE command in router environment successfully.
4343 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4345 * Show the version of the remote client (or server) when connecting
4346 to the server. It is logged to the log file. Affected file
4347 is silcd/protocol.c.
4349 * Fixed the KILLED notify handling in the client library. The
4350 client must be removed from all channels when receiving the
4353 Also, do not remove the client entry when giving the KILL
4354 command but when the KILLED notify is received.
4356 * Removed silc_idlist_find_client_by_nickname from the server.
4357 Not needed anymore. Affected files silcd/idlist.[ch].
4359 * Implemented the CHANNEL_CHANGE notify type handling to the
4360 server. Affected file silcd/server.c.
4364 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4366 * Added silc_server_send_notify_invite to send the INVITE
4367 notify between routers.
4369 * Implemented the INVITE command correctly to the server.
4371 * Implemented the INVITE notify type handling in the server.
4373 * Implemented the INVITE command to the client library and on the
4376 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4378 * Added function silc_server_get_client_resolve to find the
4379 client entry by ID from all ID lists and then resolve it
4380 (using WHOIS) if it cannot be found. Affected file is
4383 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4385 * Implemented the BAN command to the client library.
4387 * The JOIN command in the server now checks the invite list
4390 * Changed the silc_command_reply_payload_encode_va and the
4391 silc_command_payload_encode_va to support that if argument is
4392 NULL it ignores and checks the next argument. Affected file
4393 lib/silccore/silccommand.c.
4395 * Added silc_server_send_notify_ban to send the BAN notify
4396 type between routers.
4398 * Chaned the silc_notify_payload_encode to support that if
4399 argument is NULL it ignores and checks the next argument.
4400 Affected file lib/silccore/silcnotify.c.
4402 * Tested ban lists in router environment successfully.
4404 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4406 * Implemented BAN command to the server, in silcd/command.[ch].
4408 * Removed the BAN and INVITE_LIST modes from the CMODE command
4411 * Added function silc_string_match to regex match two strings.
4412 Affected files lib/silcutil/silcutil.[ch].
4414 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4416 * Redefined parts of the SilcChannelEntry in the server to support
4417 the new ban and invite lists.
4419 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4421 * Redefined the INVITE command. The same command can be used to
4422 invite individuals to the channel but also to manage the invite
4423 list of the channel (to add to and remove from the invite list).
4424 Updated the protocol specs.
4426 * Added new command SILC_COMMAND_BAN that can be used to manage
4427 the ban list of the channel. Updated the protocol specs.
4429 * Removed the channel modes: the SILC_CMODE_BAN and the
4430 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4431 in the CMODE command. The equivalent features are now available
4432 using INVITE and BAN commands. Updated the protocol specs.
4434 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4435 in the network about change in the current ban list. The notify
4436 type is not used by the client.
4438 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4439 support the invite lists.
4441 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4443 * Added new function silc_string_regexify that converts string
4444 including wildcard characters into regex string that can
4445 be used by the GNU regex library. Added into the file
4446 lib/silcutil/silcutil.[ch].
4448 Added silc_string_regex_combine to combine to regex strings
4449 into one so that they can be used as one regex string by
4450 the GNU regex library. Added into the file
4451 lib/silcutil/silcutil.[ch].
4453 Added silc_string_regex_match to match two strings. It returns
4454 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4456 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4458 * Imported GNU regex to the soruce tree into lib/contrib.
4459 Fixed some compiler warning from the regex.c.
4461 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Fixed MOTD command in the server to work in router environment.
4465 * Fixed the MOTD command in the client library to support
4466 the server argument in the command.
4468 * Added `nickname_len' argument to the silc_idlist_add_client
4469 in the server, as the `nickname' argument may be binary data
4472 * Added silc_idlist_get_channels to return all channels from
4475 * Implemented LIST command to the server. Affected file is
4478 * Implemented the LIST command to the client library and on the
4481 * Added [<user count>] argument to the LIST command reply.
4482 With private channels the user count is not shown.
4484 * Updated TODO and README.
4486 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4488 * The client entry's data.registered must be TRUE even with
4489 global client entry on global client list. The data.registered
4490 is used to check whether the client is anymore in the network,
4491 for example with WHOWAS command so it must be valid.
4493 * Fixed the WHOWAS command in the server. It now actually works
4494 in router environment. Added function into silcd/command_reply.c
4495 silc_server_command_reply_whowas_save.
4497 * Added silc_idlist_purge function to the silcd/idlist.c
4498 to periodically purge the ID Cache.
4500 * Fixed INFO command in the server. It works now in router
4501 environment. Added <server name> argument to the INFO command
4502 reply. Updated the protocol specs.
4504 * Fixed minor bug in silc_idcache_purge to not purge if the
4505 expire value is zero.
4507 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4508 they were buggy because of the WHOWAS information.
4510 * Fixed local command MSG to handle the async resolving of
4511 the remote client properly. It used to fail the first MSG.
4512 Affected file silc/local_command.c.
4514 * Added `data_len' field to SilcIDCache context.
4516 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4518 * Update TODO. Todo in commands in the server.
4520 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4522 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4523 used by routers as broadcast packet to inform other routers
4524 about the changed user mode.
4526 Implemented the notify handling in the server. Affected file is
4527 silcd/packet_receive.c. Added the function
4528 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4530 * Added new generic Channel Payload and deprecated the New Channel
4531 Payload. The New Channel Payload is now the generic Channel
4534 * Added new argument `mode' to the silc_server_send_new_channel
4535 as it is required in the Channel Payload now.
4537 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4538 and created a new and real SilChannelPayload to represent the
4539 new generic Channel Payload. Implemented the encode/decode
4540 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4542 * Added silc_server_get_client_channel_list to return the list
4543 of channels the client has joined for WHOIS command reply.
4544 Affected file silcd/server.[ch].
4546 * Implemented the channel list sending in the WHOIS command reply
4547 in server and in the client.
4549 Implemented the channel list displaying on the user interface
4550 as well. Affected file silc/client_ops.c.
4552 * Added silc_channel_payload_parse_list to parse list of Channel
4553 Payloads. It returns SilcDList list of SilcChannelPayloads.
4554 Client for example can use this function to parse the list of
4555 channels it receives in the WHOIS command reply. The caller
4556 must free the list by calling silc_channel_payload_list_free.
4557 Affected files lib/silccore/silcchannel.[ch].
4559 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4561 * Added one new argument <user mode> to the WHOIS command reply
4562 to return the mode of the user in SILC. Updated the protocol
4565 Implemented it to the server and client.
4567 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4569 * Fixed the mode printing on the user interface on joining.
4570 Affected file silc/client_ops.c.
4572 * Implemented the UMODE command and user modes in general to the
4573 client library and to the user interface.
4575 * Implemented the UMODE command to the server.
4577 * The server now sends UNKNOWN_COMMAND error status if client sends
4578 unknown command. Affected file silcd/command.c.
4580 * All server commands now handle the command identifier the right
4581 way when sending the command reply to the client. The client can
4582 use to identify the command replies with the identifier.
4584 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4586 * Added silc_server_get_client_route to resolve the route to
4587 the client indicated by the client ID. Affected file is
4590 * Added silc_server_relay_packet as general function to relay
4591 packet to arbitrary destination. This deprecates functions
4592 like _send_private_message_key, _relay_notify etc. Affected
4593 file is silcd/packet_send.[ch].
4595 Removed silc_server_send_key_agreement,
4596 silc_server_send_private_message_key and
4597 silc_server_packet_relay_notify functions from the file
4598 silcd/packet_send.[ch].
4602 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4603 server. Affected file silcd/packet_receive.[ch].
4605 * Implemented the KILL command to the client. Implemented the
4606 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4607 Affected files lib/silcclient/command[_reply].c and
4608 lib/silcclient/client_notify.c. Implemented the KILL notify
4609 printing in the user inteface.
4611 * Fixed a lot silc_parse_nick memory leaks from the client
4612 library in the file lib/silcclient/command.c.
4614 * Changed the silc_server_send_notify_on_channels's `sender'
4615 argument from SilcSocketConnection to SilcClientEntry to
4616 check the sender as entry and not as connection object and not
4617 to send to the client provided as argument. The affected file
4618 is silcd/packet_send.[ch].
4620 * The notify packets that are destined directly to the client used
4621 to not to be processed by the server. Now changed that and the
4622 server processes all notify packets. After relaying the packet
4623 to the client the notify packet is processed in the server.
4625 * The silc_server_free_client_data now checks whether there is
4626 pending outgoing traffic for the client and purges the data to
4627 the network before removing the client entry.
4629 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4632 an client is killed from the SILC Network. Updated the protocol
4635 Added new function silc_server_send_notify_killed to the
4636 silcd/packet_send.[ch].
4638 * Added function silc_server_packet_relay_notify to relay notify
4639 packets that are destined directly to a client. In this case
4640 the server does not process the notify packets but merely relays
4641 it to the client. Affected file silcd/packet_send.[ch].
4643 Added also silc_server_packet_process_relay_notify to check
4644 whereto relay the notify. Affected file is
4645 silcd/packet_receive.[ch].
4647 * Implemented the KILL command to the server.
4651 * Added the backup schema desgined last fall to the protocol
4652 specs for everyone to see. The specification is in the
4653 *-spec-xx.txt draft and the packet type definitions for the
4654 backup routers is in *-pp-xx.txt draft. Thusly, added also
4655 new packet type SILC_PACKET_CELL_ROUTERS.
4657 * A big security problem in the implementation discovered. The
4658 signoff of an client did not cause new channel key generation
4659 which it of course should've done. The channel keys must be
4660 always re-generated when client leaves (or signoffs) the channel.
4661 The silc_server_remove_from_channels funtion now handles
4662 the channel key re-generation.
4664 * Added `sender' argument to the silc_server_send_notify_on_channels
4665 to not to send the client provided as argument. Affected file
4666 silcd/packet_send.[ch].
4668 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4670 * Implemented OPER and SILCOPER commands into the server and
4673 * Added silc_auth_verify and silc_auth_verify_data to verify
4674 the authentication directly from the authentication payload.
4675 It supports verifying both passphrase and public key based
4676 authentication. Affected file lib/silccore/silcauth.[ch].
4678 * Added `hash' field to the SilcIDListData structure. It is the
4679 hash negotiated in the SKE protocol. Affected file is
4682 * Slight redesigning of the SilcAuthPayload handling routines.
4683 Do not send SilcPKCS but SilcPublicKey as argument.
4685 * Implemented the public key authentication support to the
4686 serverconfig. The public key is loaded from the provided path
4687 and saved as authentication data to void * pointer. Thus,
4688 changed the unsigned char *auth_data to void *auth_data;
4690 * Fixed SHUTDOWN command to send the reply before the server
4691 is shutdown. :) Affected file silcd/command.c.
4693 * Fixed fatal bug in CONNECT command. The hostname was invalid
4694 memory and server crashed. Affected file silcd/command.c.
4696 * Fixed fatal bug in CLOSE command. The server_entry became
4697 invalid but was referenced later in the command. Affected file
4700 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * Fixed fatal bug in failure packet handling. Server ignored
4703 the failure and thus crashed when it came.
4707 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4709 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4710 that the command may be executed only once in (about) 2 seconds.
4711 The old SILC_CF_LAG flag is same but allows command bursts up
4712 to five before limiting.
4714 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4715 server code. Various commands now includes the CF_LAG_STRICT
4716 flag to disallow any kind of miss-use of the command.
4718 * Fixed the silc_buffer_unformat to not to allocate any data
4719 if the length of the data is zero. It used to allocate the
4720 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4722 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4724 * Changed the format of AdminConnection configuration section
4725 in the server. Added username of the admin to the format.
4726 Affected files silcd/serverconfig.[ch].
4728 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4729 to return admin configuration data by host, username and/or
4732 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4734 * Implemented WHOWAS command to the server. Added the functions:
4736 silc_server_command_whowas_parse,
4737 silc_server_command_whowas_send_reply,
4738 silc_server_command_whowas_from_client and
4739 silc_server_command_whowas_from_server
4741 * Added <Client ID> argument to the WHOWAS command reply. Updated
4742 the protocol specs accordingly.
4744 * Implemented WHOWAS command and command_reply to the client
4747 Implemented the WHOWAS printing on the user interface.
4749 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4751 * Added new argument to the WHOWAS command reply, the real name.
4752 It is an optional argument. Updated the protocol specs.
4754 * Added SilcIDCacheDestructor callback that is registered when
4755 the SilcIDCache is allocated. The callback is called when
4756 an cache entry in the ID Cache expires, or is purged from the
4757 cache. Added into lib/silccore/idcache.[ch].
4759 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4760 to destruct the client entries when the cache entry expires.
4761 Other ID Cache's in server and in the client library ignores
4764 * If the ID Cache entry's `expire' field is zero then the entry
4765 never expires. Added boolean `expire' argument to the
4766 silc_idcache_add function in the lib/silccore/idcache.[ch].
4767 If it is TRUE the default expiry value is used.
4769 * Added silc_server_free_client_data_timeout that is registered
4770 when client disconnects. By default for 5 minutes we preserve
4771 the client entry for history - for WHOWAS command.
4773 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4775 * Added support to the server to enforce that commands are not
4776 executed more than once in 2 seconds. If server receives
4777 commands from client more frequently, timeout is registered
4778 to process the commands. Affected file silcd/command.c.
4779 Added new function silc_server_command_process_timeout.
4781 * Changed NICK_NOTIFY handling in client library to check that
4782 if the client's nickname was changed, so there is no need to
4783 resolve anything from the server.
4785 * Removed error printing from the WHOIS and IDENTIFY commands.
4786 If error occurs then it is ignored silently in the client library.
4787 The application, however, may map the received error to
4788 human readable error string. The application currently maps
4789 the NO_SUCH_NICKNAME error to string.
4791 * Made the command status message public to the application. Moved
4792 them from lib/silcclient/command_reply.c to
4793 lib/silcclient/command_reply.h. The application can map the
4794 received command status to the string with the
4795 silc_client_command_status_message function.
4797 * Added check to the server to check that client's ID is same
4798 as the Source ID in the packet the client sent. They must
4801 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4803 * Added dist-bzip hook to the Makefile.am to make bzip2
4804 compressed distributions.
4806 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4808 * Server now enforces the maximum length for the nickname and
4809 the channel as protocol specification dictates. 128 bytes for
4810 nickname and 256 bytes for channel name.
4812 * Moved the WHOIS printing to the application. The client libary
4813 does not print out the WHOIS information anymore, the application
4814 must do it. Renamed silc_client_command_reply_whois_print to
4815 the silc_client_command_reply_whois_save.
4817 The client's idle time is also sent to the application now, and
4818 the idle is shown on screen.
4820 * Added silc_client_command_reply_identify_save to save the
4821 received IDENTIFY entries.
4823 * Do not check for channel private keys in message sending and
4824 reception if the channel does not have the PRIVKEY mode set.
4825 Affected file lib/silclient/client_channel.c.
4827 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4829 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4830 just surfaced after chaning the JOIN procedure.
4832 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4834 * Added silc_client_get_clients_by_list to get client entries
4835 from Client ID list, that is returned for example by JOIN
4836 and USERS command replies. The application should use this
4837 function for example when JOIN command reply is received to
4838 resolve the clients already on the channel (library does not
4839 do that anymore as USERS command reply is not used in the JOIN
4840 procedure anymore). Affected files lib/silcclient/silcapi.h and
4841 lib/silcclient/idlist.c.
4843 * JOIN command reply and USERS command reply returns now SilcBuffer
4844 pointers instead of unsigned char pointers when returning
4845 the client list and mode list.
4847 * Added <Client ID> argument to the JOIN command reply, mainly
4848 for the server to identify for which client the command was
4849 originally sent. Updated protocol specs accordingly.
4851 * Added SilcDlist private_key pointer to the SilcChannelEntry
4852 in the client to support the channel private keys. Affected
4853 file is lib/silcclient/idlist.h.
4855 * Added SilcChannelPrivateKey argument to the function
4856 silc_client_send_channel_message so that application can choose
4857 to use specific private ke if it wants to. If it is not provided,
4858 the normal channel key is used, unless private keys are set.
4859 In this case the first (key that was added first) is used
4860 as the encryption key.
4862 * Implemented the support for channel private key handling.
4863 Implemented the following functions:
4865 silc_client_add_channel_private_key,
4866 silc_client_del_channel_private_keys,
4867 silc_client_del_channel_private_key,
4868 silc_client_list_channel_private_keys and
4869 silc_client_free_channel_private_keys
4871 Affected file lib/silcclient/client_channel.c.
4873 * Added the support for the private keys in the channel message
4874 sending and encryption and in the message reception and
4875 decryption. Affected funtions are
4876 silc_client_send_channel_message and silc_client_channel_message.
4878 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4880 * Added SKE's key verify callback to the client library's
4881 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4883 * Removed the statement that server (or router) must send USERS
4884 command reply when joining to the channel so that the client
4885 knows who are on the channel. Instead, the client list and
4886 client's mode list is now sent in the JOIN command reply to the
4887 client who joined channel. This is better solution.
4889 * Added function silc_server_get_users_on_channel and function
4890 silc_server_save_users_on_channel to the silcd/server.[ch].
4892 * Removed function silc_server_command_send_users from the
4895 * Do not show topic on the client library anymore. The topic is
4896 sent in the command reply notify to the application and the
4897 application must show the topic now.
4899 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4901 * Added client searching by nickname hash into the IDENTIFY and
4902 WHOIS commands in the server as they were clearly missing from
4903 them. Affected file is silcd/command.c.
4905 * Fixed a bug in private message receiving in the client library.
4906 The remote ID was freed and it wasn't supposed, now it is
4909 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4911 * Minor fix to the channel payload; allocate the data area, as it
4912 needs to be of specific length.
4914 * If the key agreement port is zero then the operating
4915 system will define the bound port. Affected files are
4916 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4918 * Added new function silc_channel_payload_decrypt into the file
4919 lib/silccore/silcchannel.[ch].
4921 * Moved the channel message etc, check from silc_packet_decrypt
4922 to applications. The library calls now a generic
4923 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4924 when the packet is either normal or special. This was done to
4925 allow more wide range of checking that was not allowed when
4926 the code was in library. Now applications can do virtually any
4927 checks to the packet and return to the library the decision how
4928 the packet should be processed. Affected files are
4929 lib/silccore/silcpacket.[ch].
4931 Added silc_server_packet_decrypt_check to the server and
4932 silc_client_packet_decrypt_check to the client library.
4934 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4935 to send with specified source and destination information.
4937 * Channel message delivery between routers was broken after the
4938 channel key distribution was fixed earlier. The channel key
4939 was used be to distributed to other routers as well which is not
4940 allowed by the protocol. Now this is fixed and channel keys
4941 really are cell specific and the channel message delivery between
4942 routers comply with the protocol specification.
4944 * Fixed various commands in server to check also the global list
4945 for the channel entry and not just the local list. The affected
4946 file silcd/command.c.
4948 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4950 * Added assert()s to buffer formatting and unformatting routines
4951 to assert (if --enable-debug) when error occurs. Affected
4952 file: lib/silcutil/silcbuffmt.c.
4954 * Changed to auto-reconnect to check whether the remote host is
4955 router and register the re-connect timeout if it is. It used
4956 to check that whether we are normal server, but router must do
4957 auto-reconnect with another router as well. Affected file
4960 * Removed the [<key len>] option from CMODE command as the cipher
4961 name decides the key length, nowadays. See the defined ciphers
4962 from the protocol specification.
4964 * Added [<hmac>] option to the CMODE command to define the HMAC
4965 for the channel. Added SILC_CMODE_HMAC channel mode.
4967 * Added [<hmac>] option for the JOIN command so that user can
4968 select which HMAC is used to compute the MACs of the channel
4971 * Added Hmac field to the Channel Message Payload. The integrity
4972 of plaintext channel messages are now protected by computing
4973 MAC of the message and attaching the MAC to the payload. The
4974 MAC is encrypted. Now, it is clear that this causes some
4975 overhead to the size of the packet but rationale for this is that
4976 now the receiver can verify whether the channel message decrypted
4977 correctly and also when private keys are set for the channel the
4978 receiver can decrypt the packet with several keys and check from
4979 the MAC which key decrypted the message correctly.
4981 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4982 lib/silccrypt/silccipher.[ch].
4984 * Added silc_hash_len to return the digest length into the
4985 lib/silcrypt/silchash.[ch].
4987 * Rewrote parts of Silc Channel Payload interface in the
4988 lib/silccore/silcchannel.[ch]. The encode function now also
4989 encrypts the packet and parse function decrypts it.
4991 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4993 * Fixed a minor formatting bug in the SKE's key material processing.
4994 It actually might have processed the keys wrong way resulting
4997 * Redefined the mandatory HMAC algorithms and added new algorithms.
4998 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4999 and hmac-md5 truncated to 96 bits. The mandatory is now
5000 hmac-sha1-96. Rest are optional (including the one that used
5001 to be mandatory). Rationale for this is that the truncated HMAC
5002 length is sufficient from security point of view and can actually
5003 make the attack against the HMAC harder. Also, the truncated
5004 HMAC causes less overhead to the packets. See the RFC2104 for
5007 * Added new [hmac] configuration section. The SKE used to use
5008 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5009 is of course wrong. The official names that must be proposed in
5010 the SKE are the ones defined in the protocol specification
5011 (hmac-sha1-96 for example). The user can configure any hmac
5012 using any hash function configured in the [hash] section. At
5013 least, the mandatory must be configured.
5015 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5017 * Added HMAC list to the SKE proposal list. It has now both
5018 hash algorithm list and HMAC list. This makes the protocol
5019 incompatible with previous versions. The SKE now seems to work
5020 the way it is supposed to work, for the first time actually.
5022 * Defined plain Hash algorithms to the protocol specification.
5025 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Implemented support for key agreement packets into the server.
5028 Added functions silc_server_key_agreement and
5029 silc_server_send_key_agreement. Other than these functions,
5030 server has nothing to do with this packet.
5032 * Added support for private message key packets into the server.
5033 Added functions silc_server_private_message_key and
5034 silc_server_send_private_message_key.
5038 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5039 called in the protocol's final callback instead in the END
5040 protocol state. This makes a little more sense and in the same
5041 time in client we can use the same protocol routines for normal
5042 key exchange and to key agreement packet handling as well.
5044 * Added to both client's and server's KE protocol context the
5045 SilcSKEKeyMaterial pointer to save the key material. We will
5046 bring the key material to the protocol's final callback by doing
5047 this. The final callback must free the key material.
5049 * Added SKE's packet_send callback into client's KE protocol
5050 context so that the caller can choose what packet sending function
5051 is used. This way we can use different packet sending when
5052 doing normal SKE when doing key agreement packet handling (in
5053 the key agreement packet handling we do not want to encrypt
5056 * Implemented the responder side of the key agreement routines
5057 in the client. The client can now bind to specified port and
5058 accept incoming key negotiation. The key material is passed
5059 to the application after the protocol is over.
5061 * Implemented the processing of incoming Key Agreement packet
5062 in the client. Added function silc_client_key_agreement to
5065 * Implemented the intiator side of the key agreement routines
5066 in the client. The client can now initiate key agreement with
5067 another remote client. The key material is passed to the
5068 application after the protocol is over.
5070 * Created client_keyagr.c to include all the key agreement
5073 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5074 SILC_TASK_CALLBACK except that it is not static.
5076 * Created client_notify.c and moved the Notify packet handling
5077 from the client.[ch] into that file.
5079 * Created client_prvmsg.c and moved all private message and
5080 private message key routines from the client.[ch] into that file.
5082 * Create client_channel.c and moved all channel message and
5083 channel private key routines from the client.[ch] into that file.
5085 * Changed silc_client_get_client_by_id_resolve to resolve with
5086 WHOIS command instead of IDENTIFY command, in the file
5087 lib/silclient/idlist.c.
5089 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5091 * Implemented the SKE's responder side to the Client library.
5093 * When FAILURE is received to the protocol do not trust it
5094 blindly. Register a timeout to wait whether the remote closes
5095 the connection as it should do it, only after that process the
5096 actual failure. This was changed to both client and server.
5098 * Added client_internal.h to include some of the structures
5099 there instead of client.h in lib/silcclient/.
5101 * Added function silc_task_unregister_by_callback to unregister
5102 timeouts by the callback function.
5104 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5106 * Some "Incomplete WHOIS info" errors has been appearing on the
5107 log files. Took away the entry->userinfo check from WHOIS
5108 reply sending. The entry->userinfo is now " " if client did not
5109 provide one. I thought this was fixed earlier but something
5110 is wrong still. Let's see if the error still appears.
5112 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5114 * Fixed a minor bug in the login when the channel key is
5115 re-generated in the server. It used to generate the key in
5116 wrong order and thus caused problems in the channel traffic.
5118 * Fixed a minor bug in channel key distsribution after
5119 KICK command. The key was not sent to the router even though
5122 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5124 * Added silc_ske_process_key_material_data as generic routine
5125 to process any key material as the SILC protocol dictates. The
5126 function is used by the actual SKE library but can be used by
5127 applications as well. This relates to the private message keys
5128 and the channel private keys since they must be processed the
5129 same way the normal SILC session keys. The protocol dictates
5130 this. Affected files: lib/silcske/silcske.[ch].
5132 Added also silc_ske_free_key_material to free the
5133 SilcSKEKeyMaterial structure.
5135 * Defined silc_cipher_set_key function to set the key for
5136 cipher without using the object's method function. The affected
5137 files: lib/silccrypt/silccipher.[ch].
5139 * Implemented silc silc_client_add_private_message_key,
5140 silc_client_add_private_message_key_ske,
5141 silc_client_del_private_message_key,
5142 silc_client_list_private_message_keys and
5143 silc_client_free_private_message_keys functions in the
5146 Added functions silc_client_send_private_message_key to send
5147 the Private Message Key payload and silc_client_private_message_key
5148 to handle incoming Private Message Key payload.
5150 * Added Cipher field to the Private Message Key payload to set
5151 the cipher to be used. If ignored, the default cipher defined
5152 in the SILC protocol (aes-256-cbc) is used.
5154 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5156 * Removed lib/silcclient/ops.h file.
5158 Redefined parts of the SILC Client Library API. Created new
5159 file silcapi.h that deprecates the ops.h file and defines the
5160 published Client Library API. Defined also private message key
5161 API and channel private key API into the file.
5163 This is the file that the application must include from the
5164 SILC Client Library. Other files need not be included by
5165 the application anymore.
5167 * Added new key_agreement client operation callback and also
5168 defined the Key Agreement library API for the application.
5170 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5172 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5173 is used by clients to request key negotiation between another
5174 client in the SILC network. If the negotiation is started it
5175 is performed using the SKE protocol. The result of the
5176 negotiation, the secret key material, can be used for example
5177 as private message key.
5179 Implemented the Key Agreement payload into the files
5180 lib/silccore/silauth.[ch].
5182 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Redefined ciphers for the SILC protocol. Added some new ciphers
5185 and defined the key lengths for the algorithms. Changed the
5186 code accordingly. The default key length is now 256 bits.
5188 * Fixed SKE key distribution function silc_ske_process_key_material
5189 when the key length is more than 128 bits. The default key
5190 length in SILC is now 256 bits.
5192 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5193 to indicate unsupported algorithm.
5195 * Renamed rijndael.c to aes.c and all functions as well.
5197 * Fixed a long standing channel key setting bug in client library.
5198 Weird that it has never surfaced before.
5200 * Fixed bug in channel deletion. If the entire channel is removed
5201 then it must also delete the references of the channel entry
5202 from the client's channel list as the client's channel entry and
5203 the channel's client entry share same memory.
5205 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Implemented CONNECT and SHUTDOWN commands in the client.
5209 * Implemented CLOSE command to the client.
5211 * Added the function silc_idlist_find_server_by_name into the
5212 files silcd/idlist.[ch].
5214 Added the function silc_idlist_find_server_by_conn into the
5215 files silcd/idlist.[ch].
5217 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5219 * DIE command was renamed to SHUTDOWN. Updated the both code
5222 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5223 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5225 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5228 * Added function silc_server_create_connection function to create
5229 connection to remote router. My server implementation actually
5230 does not allow router to connect to normal server (it expects
5231 that normal server always initiates the connection to the router)
5232 so the CONNECT command is only good for connecting to another
5235 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5237 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5238 or some other client was kicked from the channel.
5240 Implemented the handling of the notify type to both client
5243 Implemented silc_server_send_notify_kicked to send the KICKED
5244 notify. It is used to send it to the server's primary router.
5246 * Implemented the KICK command into server and client.
5248 * Added `query' argument to the silc_idlist_get_client function
5249 to indicate whether to query the client from server or not if
5252 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5253 to indicate that the client is not channel founder.
5257 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5259 * Removed the rng context from SilcPacketContext structure and
5260 changed that the packet routine uses the Global RNG API.
5262 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5264 * Added support for quit message that client can "leave" on the
5265 channel when it quits the SILC. It is ditributed inside the
5266 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5268 Added silc_server_free_client_data that will take the
5269 signoff message as argument.
5271 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5273 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5275 * Updated parts of the protocol specification to keep it up
5278 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5280 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5281 payloads in one packet.
5283 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5284 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5285 use now the new List flag.
5287 * Also deprecated the following packet types: REPLACE_ID,
5288 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5290 * Added list support for Notify packet in server.
5292 * Added silc_server_send_notify_channel_change to send the
5293 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5294 the silc_server_send_replace_id.
5296 * Added silc_server_send_notify_nick_change to send the
5297 NICK_CHANGE notify type. Deprecates the function
5298 silc_server_send_replace_id.
5300 * Added silc_server_send_notify_join to send the JOIN notify type.
5301 Deprecates the function silc_server_send_new_channel_user.
5303 * Added silc_server_send_notify_leave to send LEAVE notify type.
5304 Deprecates the function silc_server_send_remove_channel_user.
5306 * Added silc_server_send_notify_cmode and
5307 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5308 types. Deprecates the silc_server_send_set_mode function.
5310 * Added SERVER_SIGNOFF notify type to indicate that server has
5311 quit. This means that all clients on the channel from that
5312 server will drop. This can be also used when netsplit happens.
5314 Deprecated REMOVE_ID packet type since it is not needed anymore
5317 Added silc_server_send_notify_server_signoff to send the
5318 SERVER_SIGNOFF notify type. Deprecates the function
5319 silc_server_send_remove_id.
5321 Added also silc_server_send_notify_signoff to send the
5322 SIGNOFF notify type.
5324 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5325 SILC protocol from this day on. Changed the protocol
5326 specification as well.
5328 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5329 notify type. It is used between routers to notify about
5330 topic changes on a channel.
5332 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5335 * Partly updated the protocol specification to comply with the
5336 changes now made. It is still though a bit outdated.
5338 * The JOIN notify type now takes one extra argument <Channel ID>.
5339 The packet used to be destined to the channel but now the
5340 JOIN type may be sent as list thus it is impossible to
5341 destine it to any specific channel. By adding this argument
5342 it is again possible.
5344 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5346 * Added CREDITS file. The CHANGES and CREDITS file will appear
5347 in the distribution as well.
5349 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5351 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5352 types in the server's silcd/packet_receive.c.
5354 * Implemented CMODE and CUMODE to work in router environment.
5356 * Fixed minor encoding and decoding buglet from the
5357 lib/silccore/silcmode.c.
5359 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5362 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5364 * Changed all SilcConfigServer* and silc_config_server* to
5365 SilcServerConfig* and silc_server_config*, respectively.
5368 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5370 * Associated the ID (client or server ID) to the Authentication
5371 Payload to avoid any possibility of forging. Updated the
5372 protocol specification and the code accordingly.
5374 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5376 * The RSA key length is now save to the RsaKey context in the
5377 key generation process in lib/silccrypt/rsa.c. The key length
5378 is now used to figure out the maximum size of the block allowed
5379 to be encrypted/signed.
5381 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5382 is equivalent to the silc_mp_mp2bin but does not allocate any
5385 * Changed silc_mp_mp2bin API to take length argument. If it is
5386 non-zero then the buffer is allocated that large. If zero, then
5387 the size is approximated using silc_mp_sizeinbase, which however
5390 * Created Global RNG API which is global RNG that application can
5391 initialize. After initializing, any routine anywhere in the
5392 code (including library) can use RNG without allocating a new
5393 RNG object. This was done to allow this sort of use of the
5394 RNG in code that has no chance to allocate RNG object. All
5395 applications currently allocate this and many routines in the
5396 library use this. Affected file lib/silccrypt/silcrng.[ch].
5398 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5399 it to use the Global RNG API.
5401 * Defined Authentication Payload into protocol specification that
5402 is used during SILC session to authenticate entities. It is
5403 used for example by client to authenticate itself to the server
5404 to obtain server operator privileges.
5406 Implemented this payload into the lib/silccore/silcauth.[ch].
5407 Implemented also routines for public key based authentication
5408 as the new protocol specification dictates.
5410 Moved definitions of different authentication methods from
5411 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5413 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5414 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5415 silc_pkcs_verify_with_hash functions into the file
5416 lib/silccrypt/silcpkcs.[ch].
5418 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5420 * The client entry's userinfo pointer must be always valid.
5421 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5422 will fail since it requires the userinfo. Now, the userinfo
5423 is allocated as "" if actual userinfo does not exist. Actually,
5424 it must exist and it is totally Ok to drop client connections
5425 that does not announce the userinfo. However, we will make
5426 this workaround for now.
5428 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5429 to return the remote port by socket.
5431 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5433 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5434 SILC_SERVER_PENDING_EXEC and added an new macro
5435 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5436 data or when error occurs while processing the pending command.
5438 Added new argument `destructor' into silc_server_command_pending
5439 and to the SilcServerCommandPending object. This destructor is
5440 now called after calling the pending callback or if error occurs
5441 immediately. If error occurs the actual pending callback won't
5442 be called at all - only the destructor. The destructor may be
5443 NULL if destructor is not needed.
5445 All this applies for client library code as well. Similar
5446 changes were made there as well for the pending commands.
5448 In the client, the application must now allocate the
5449 SilcClientCommandContext with the silc_client_command_alloc
5452 * Added reference counter to the SilcServerCommandContext. Added
5453 function silc_server_command_alloc and silc_server_command_dup
5456 Same type of functions added to the client library for the same
5459 * Removed the cmd_ident from IDListData away since it is now
5460 global for all connections. It is the command identifier used
5461 in command sending and with pending commands. The affected file
5464 * Added reference counter to the SilcSocketConnection objecet to
5465 indicate the usage count of the object. The object won't be
5466 freed untill the reference counter hits zero. Currently only
5467 server uses this, and client ignores it. The client must be
5468 set to use this too later. The affected files are
5469 lib/silccore/silcsockconn.[ch]. Added also the function
5470 silc_socket_dup to increase the reference counter.
5472 This was mainly added because it is possible that the socket
5473 is removed underneath of pending command or other async
5474 operation. Now it won't be free'd and proper DISCONNECTING
5475 flags, etc. can be set to avoid sending data to connection that
5476 is not valid anymore.
5478 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5479 the connection. After that it sets SILC_SET_DISCONNECTED.
5480 It is, however, possible that the socket data is not still freed.
5481 The silc_server_packet_process now checks that data is not
5482 read or written to connection that is DISCONNECTED. The socket
5483 get's freed when the reference counter hits zero.
5485 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5487 * Changed the client operation API: channel_message operation's
5488 `sender' is now the client entry of the sender, not the nickname
5489 and the `channel' is the channel entry, not the channel name.
5491 In the private_message operation the `sender' is now also the
5492 client entry of the sender not the nickname.
5494 Affected file is lib/silcclient/ops.h and all applications
5495 using the client operations.
5497 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5499 * Moved the calling of ops->connect() from connect_to_server_final
5500 into receive_new_id functin since that is the point when the
5501 client is actually allowed to send traffic to network. The
5502 affected file is lib/silcclient/client.c.
5504 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5506 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5507 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5508 (if needs broadcasting) instead of broadcasting the packets one
5509 by one which would make a burst in the network traffic.
5511 * Added `broadcast' argument to the functions in silcd/server.[ch]
5512 silc_server_create_new_channel[_with_id] to indicate whether
5513 to send New Channel packet to primary router.
5515 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Added new function into the silcd/server.[ch] files:
5518 silc_server_create_new_channel_with_id to create new channel with
5519 already existing Channel ID.
5521 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5522 lib/silccore/silcpacket.h. This packet is used t send list of
5523 Set Mode payloads inside one packet. Server uses this to set
5524 the modes for the channels and clients on those channels, that it
5525 announced to the router when it connected to it. The protocol
5526 specification has been updated accordingly.
5528 * The silc_server_new_channel did not handle the packet coming
5529 from normal server as it normally does not send that. However,
5530 when it announces its channels it does send it. Implemented
5531 the support for that.
5533 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5534 into the file lib/silccore/id.h.
5536 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * Fixed memory leaks in the functions silc_idlist_del_client,
5539 silc_idlist_del_channel and silc_idlist_del_server in the file
5540 silcd/idlist.c. All of those leaked like a sieve.
5542 * Fixed some small memory leaks in the client's function
5543 silc_client_notify_by_server.
5545 * Added functions into silcd/server.c: silc_server_announce_clients,
5546 silc_server_announce_channels and silc_server_announce_server.
5547 These functions are used by normal and router server to announce
5548 to its primary router about clients, channels and servers (when
5549 router) that we own. This is done after we've connected to the
5552 These functions effectively implements the following packet types:
5553 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5554 and SILC_PACKET_NEW_ID_LIST.
5556 * Added new functions into the silcd/packet_receive.[ch]:
5557 silc_server_new_id_list, silc_server_new_channel_list and
5558 silc_server_new_channel_user_list to handle the incoming
5559 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5561 * Added support of changing Channel ID in the function
5562 silc_server_replace_id. If the server that announces a channel
5563 to the router already exists in the router (with same name but
5564 with different Channel ID), router is responsible to send
5565 Replace ID packet to the server and force the server to change
5566 the Channel ID to the one router has.
5568 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5569 client that the Channel ID has been changed by the router. The
5570 normal server sends this to the client. Client must start using
5571 the new Channel ID as the channel's ID.
5573 Implemented handling of this new type into lib/silcclient/client.c
5574 into the function silc_client_notify_by_server.
5576 * Added new function silc_idlist_replace_channel_id into the files
5577 silcd/idlist.[ch] to replace the Channel ID.
5579 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5581 * Call silc_server_command_identify_check always when processing
5582 the IDENTIFY command in silcd/command.c
5584 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5586 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5587 send keepalive packets. The packet can be sent by clients,
5588 servers and routers.
5590 Added function silc_socket_set_heartbeat into the file
5591 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5592 If not set, the heartbeat is not performed. The actual
5593 heartbeat is implemented in the low level socket connection
5594 library. However, application is responsible of actually
5597 Added silc_server_send_heartbeat to send the actual heartbeat
5598 packet into silcd/packet_send.[ch]. Server now performs
5599 keepalive with all connections.
5601 * Added silc_task_get_first function into lib/silcutil/silctask.c
5602 to return the timeout task with shortest timeout. There was a bug
5603 in task unregistration that caused problems. TODO has been
5604 updated to include that task system must be rewritten.
5606 * The client library will now resolve the client information when
5607 receiving JOIN notify from server for client that we know but
5608 have incomplete information.
5610 * Rewrote parts of silc_server_remove_from_channels and
5611 silc_server_remove_from_one_channel as they did not remove the
5612 channel in some circumstances even though they should've.
5614 * Encryption problem encountered in server:
5616 The LEAVE command used to send the Channel Key packet to the
5617 router immediately after generating it. However, the code
5618 had earlier sent Remove Channel user packet but not immediately,
5619 ie. it was put to queue. The order of packets in the router
5620 was that Channel Key packet was first and Remove Channel User
5621 packet was second, even though they were encrypted in the
5622 reverse order. For this reason, MAC check failed. Now, this
5623 is fixed by not sending the Channel Key packet immediately but
5624 putting it to queue. However, this is more fundamental problem:
5625 packets that are in queue should actually not be encrypted
5626 because packets that are sent immediately gets encrypted
5627 actually with wrong IV (and thus MAC check fails). So, packets
5628 that are in queue should be encrypted when they are sent to
5629 the wire and not when they put to the queue.
5631 However, the problem is that the current system has not been
5632 designed to work that way. Instead, the packet is encrypted
5633 as soon as possible and left to the queue. The queue is then
5634 just purged into wire. There won't be any fixes for this
5635 any time soon. So, the current semantic for packet sending
5638 o If you send packet to remote host and do not force the send
5639 (the packet will be in queue) then all subsequent packets to the
5640 same remote host must also be put to the queue. Only after the
5641 queue has been purged is it safe again to force the packet
5644 o If you send all packets immediately then it safe to send
5645 any of subsequent packets through the queue, however, after
5646 the first packet is put to queue then any subsequent packets
5647 must also be put to the queue.
5649 Follow these rules and everything works fine.
5651 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5653 * Added new function silc_server_remove_clients_by_server to
5654 remove all client entries from ID list when the server connection
5655 is lost. In this case it is also important to invalidate all
5656 client entires as they hold the invalid server entry. This
5657 fixes fatal bug when server has lost connection and will reconnect
5660 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5662 * Made some sanity checks to silc_server_daemonise like to check
5663 whether the requested user and group actually exists.
5665 * Added sanity check to SKE's silc_ske_responder_finish to check
5666 that the public and private key actually is valid.
5668 * Invalidate the client's nickname when receiving Replace ID
5669 packet and the Client ID is being replaced. This means that the
5670 server will query the nickname if someone needs it (client)
5673 * Sort the ID Cache in client library when the ID Cache data
5674 has changed (needs sorting).
5676 * Do not allow for SILC client to create several connections to
5677 several servers. The client does not support windows right now
5678 and generating multiple connections causes weird behaviour.
5680 Irssi-silc client does support windows and can handle several
5681 connections without problems, see: www.irssi.org and SILC plugin.
5683 * Fixed some places where client was added to the IDList. The
5684 rule of thumb is following (in order to get everything right):
5685 If the client is directly connected local client then the
5686 `connection' argument must be set and `router' argument must be
5687 NULL to silc_idlist_add_client function. If the client is not
5688 directly connected client then the `router' argument must
5689 bet set and the `connection' argument must be NULL to the
5690 silc_idlist_add_client function.
5692 * The funtion silc_server_packet_send_local_channel actually did
5693 not check whether the client was locally connected or not. It
5694 does that now. Fixed a bug related to LEAVE command.
5696 * Fixed Remove Channel User payload parsing bug in server's
5697 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5699 * The server's silc_server_save_channel_key now checks also the
5700 global ID list for the channel as it might not be in the local
5701 list. Fixed a bug related to LEAVE command.
5703 * Is this the end of the [<unknown>] buglet that has been lurking
5704 around for a long time? A little for loop fix in server's
5705 silc_server_command_whois_parse that is used by both IDENTIFY
5706 and WHOIS command. At least, this was a clear bug and a cause
5707 of one type of [<unknown>] buglet.
5709 * WHOIS and IDENTIFY commands call the function
5710 silc_server_command_[whois/identify]_check function even if
5711 we are not router server.
5713 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5715 * Added --with-gmp configuration option. If set the GMP
5716 is always compiled in the SILC source tree. If not set then
5717 it is checked whether the system has the GMP3 installed. If
5718 it has then the GMP won't be compiled (the system's headers
5719 and library is used), if it doesn't have it then the GMP is
5720 compiled in the SILC source tree.
5722 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5724 * Changed RSA private exponent generation to what PKCS #1
5725 suggests. We try to find the smallest possible d by doing
5726 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5727 not security fix but optimization.
5729 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5731 * Added new config entry [Identity] to fork the server and run
5732 it as specific user and group. A patch from Bostik.
5734 * Imported Dotconf configuration library into lib/dotconf.
5735 This will be used to create the SILC configuration files later.
5736 It will appear in the distsribution after this commit.
5738 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5740 * A big code auditing weekend happening. Auditing code for
5741 obvious mistakes, bugs and errors. Also, removing any code
5744 Removed files for being obsolete:
5746 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5747 inline in the file lib/silcutil/silcbuffer.h)
5749 o lib/silcutil/silcbufutil.c (the header has inline versions)
5751 Changed code to fix possible error conditions:
5753 o The buffer formatting routines now check that the destination
5754 buffer really has enough space to add the data. This applies for
5755 both buffer formatting and unformatting
5756 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5757 unformatting was changed to accomodate following rules:
5758 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5759 sent to the function while XXX_*STRING will not allocate or copy
5760 the data into the buffer. Instead it sets the pointer from the
5761 buffer into the pointer sent as argument (XXX_*STRING used to
5762 require that the pointer must be allocated already). This change
5763 makes this whole thing a bit more consistent and more optimized
5764 (note that the data returned in the unformatting with XXX_*STRING
5765 must not be freed now). The routines return now -1 on error.
5767 o Tried to find all code that use buffer_format and buffer_unformat
5768 and added return value checking to prevent formatting and
5769 especially unformatting errors and possible subsequent fatal
5772 o Changed ske->x and ske->KEY to mallocated pointers in
5773 lib/silcske/silcske.h. Fixed possible data and memory leak.
5775 o Added return value checking to all *_parse* functions. Fixed
5776 many memory leaks as well.
5778 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5779 so that buffer overflows would not happen. All code now also
5780 checks the return value as it can fail.
5782 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5784 * Added reconnection support to server if the normal server looses
5785 its connection to the router (for example if router is rebooted).
5786 The server performs normal reconnection strategy implemented
5787 to the server. Affected file silcd/server.c.
5789 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5791 * Added new packet type SILC_PACKET_SET_MODE that is used to
5792 distribute the information about changed modes (for clients,
5793 channels and clients channel modes) to all routers in the
5794 network. Updated the protocol specification accordingly.
5796 Added functions into silcd/packet_send.c and
5797 silcd/packet_receive.c: silc_server_send_set_mode,
5798 silc_server_set_mode.
5800 Added new files silcmode.[ch] into lib/silccore that implements
5801 the encoding and decoding of Set Mode Payload. Added new type
5802 SilcSetModePayload. Moved the definitions of different modes
5803 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5805 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5807 * Oops, a little mistake in server's connection authentication
5808 protocol. The protocol is not ended with FAILURE but with
5809 SUCCESS if the authentication is Ok. :) Affected file is
5812 * Implemented NICK_CHANGE notify handling in server in the file
5813 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5814 the local clients on the channel. After the changing nickname
5815 in router environment snhould work and the [<unknown>] nickname
5816 should appear no more.
5818 The silc_server_replace_id function that receives the Replace ID
5819 payload now sends the NICK_CHANGE notify type also in the file
5820 silcd/packet_receive.c
5822 * Changed WHOIS and IDENTIFY command to support the maximum amount
5823 of arguments defined in protocol specs (3328 arguments). This
5824 fixed a bug that caused problems when there were more than three
5827 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5829 * Added extra parameter, command identifier, to the
5830 silc_client_send_command so that explicit command identifier
5833 Changed that ID list routines uses specific command identifier
5834 when sending WHOIS/IDENTIFY requests to the server so that they
5835 can be identified when the reply comes back.
5837 Affected files lib/silcclient/command.[ch],
5838 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5840 * Added `sender' argument to silc_server_packet_send_to_channel
5841 to indicaet the sender who originally sent the packet to us
5842 that we are now re-sending. Ignored if NULL. Affected file
5843 silcd/packet_send.[ch].
5845 * Added some server statistics support in silcd/server_internal.h
5846 SilcServerStatistics structure and around the server code. Also
5847 send some nice statistics information when client is connecting
5850 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5852 * Fixed channel ID decoding in server's JOIN command reply in
5853 silcd/command_reply.c
5855 * Fixed braodcasting of replace ID payload to not to send it if
5856 we are standalone server in silcd/packet_receive.c.
5858 * Fixed all channel message sending routines to not to send
5859 packets to clients that has router set, since they are routed
5860 separately in the same function earlier. Affects file
5861 silcd/packet_send.c and all channel packet sending functions.
5863 * In USERS reply, res_argv[i] are not allocated, the table
5864 is allocated. Thus changed that free the table, not its
5867 * In server's whois_check and identify_check if the client is
5868 locally connected do not send any WHOIS commands - they are not
5871 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5873 * Fixed some minor bugs in client when sending WHOIS command. The
5874 arguments was in wrong order.
5876 * Removed statis function add_to_channel from server in
5877 silcd/command.c that was previously used with the joining but
5880 * Tested USERS command in router environment successfully with two
5881 routers, two servers and two clients.
5883 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5885 * Reorganized the USERS command and command reply in client library
5886 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5887 When the command is given by user we register a pending command
5888 callback that will reprocess the command after the reply has been
5889 received from the server. When reprocessing the packet we then
5890 display the information. Thus, the USERS information is displayed
5891 now in the command callback instead of in the command reply
5892 callback. The processing of the command is same as previously
5893 when server has sent the command reply in the JOINing process.
5895 * Added to USERS command in silcd/command_reply.c to join the client,
5896 we didn't use to know about, to the channel after we've created
5897 a client entry for it. Also, for clienet we did know already still
5898 check whether it is on the channel or not and add it if not.
5900 * Removed silc_server_command_join_notify as the function and its
5903 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5905 * Changed the client's pending command handling to the same as the
5906 server's pending command handling. It is also now possible to
5907 execute command reply functions from other command reply
5908 function as the function callbacks for commands and command
5909 replies are one and same. The pending commands are not static
5910 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5911 in client connection context. Thus, pending commands are server
5912 connection specific as it is convenient.
5914 Changed the function silc_client_command_pending and
5915 silc_client_command_pending_del and added new function
5916 silc_client_command_pending_check. Removed the
5917 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5920 * Added cmd_ident, current command identifier, to the client
5921 connection context in lib/silcclient/client.h to keep track on
5922 command identifiers used in command sending. Client's command reply
5923 function handling now supports the mandatory command identifiers.
5925 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5926 funtions in client to fully support pending command callbacks.
5928 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5929 as one of the arguments to the application in the command reply
5932 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5933 before first releasing SILC but came back. Now it is removed again
5934 and should come back nomore. The FORWARDED flag was used only
5935 by the JOINing procedure by forwarding the command packet to router.
5936 Now, the JOINing procedure has been changed to more generic (due
5937 to various router environment issues) and FORWARDED is not needed
5938 anymore for anything. The protocol specification is yet to be
5941 Now, removed silc_server_packet_forward from server and the flag
5942 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5944 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5946 * Renamed NAMES command to USERS command. The NAMES was named that
5947 due to historical reasons. Now it is renamed. Also, rewrote
5948 parts of the USERS command. The nickname list is not sent anymore
5949 by the server. Only Client ID and mode lists are sent in the USERS
5950 command. Changed this also to the protocol specification.
5952 The client now resolves the names and stuff after it receives
5953 the USERS list from the server when joining to the channel.
5955 * WHOIS and IDENTIFY commands has been changed to support multiple
5956 Client ID's per command. One can now search for multiple users
5957 in the network by sending only one WHOIS or IDENTIFY command.
5958 Changed the code and the protocol specifications.
5960 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5961 uses silc_server_command_whois_parse to parse the request. */
5963 * If normal server, do not parse the WHOIS and IDENTIFY requests
5964 before sending it to the router. Saves some time.
5966 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5968 * Fixed JOIN command on client library. Wrong number of arguments
5969 used to crash the client.
5971 * Added silc_server_channel_has_global function to check whether
5972 channel has global users or not.
5974 * Added silc_server_channel_has_local function to check whether channel
5975 has locally connected clients on the channel.
5977 * The silc_server_remove_from_one_channel now checks whether the
5978 channel has global users or not after given client was removed from
5979 the channel. It also checks whether the channel has local clients
5980 on the channel anymore. If it does not have then the channel entry
5981 is removed as it is not needed anymore.
5983 * The silc_server_notify now checks on JOIN notify whether the joining
5984 client is one of locally connected or global. If it is global then
5985 the channel has now global users on the channel and that is marked
5986 to the channel entry. Also, it now saves the global client to
5987 global list who is joining and JOINs it to the channel. This is
5988 for normal server, that is.
5990 Changed silc_server_send_notify_on_channel,
5991 silc_server_packet_relay_to_channel and
5992 silc_server_packet_send_to_channel check if we are normal server
5993 and client has router set (ie. global client) do not send the
5994 message to that client, as it is already routed to our router.
5996 * Implemented LEAVE notify type handling in silc_server_notify
5999 * Tested LEAVE command in router environment successfully. Tested
6000 with two routers, two servers and two clients.
6004 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6006 * Implemented SIGNOFF notify type handling in silc_server_notify
6009 * silc_server_remove_id now removes the client entry from all channels
6010 it has joined and thusly sends SIGNOFF notify type.
6012 * Rewrote the NAMES list generation in server by removing two excess
6013 loops. The lists are created now inside one loop.
6015 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6017 * silc_server_remove_channel_user checks now also global list
6018 for channel and client.
6020 * silc_server_new_channel_user checks now both local and global
6021 list for channel and client. Fixed a bug in client id decoding.
6022 Used to decode wrong buffer.
6024 * silc_server_channel_message checks now both local and global
6025 list for channel entry.
6027 * Tested channel joining (hence JOIN) in router environment
6028 successfully. Tested with two routers, two servers and two
6031 * Tested channel message sending in router environment successfully.
6033 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6035 * Added silc_server_save_channel_key into server.[ch] to save the
6036 received channel key in Channel Key payload processing. It is
6037 also used in JOIN command reply handling.
6039 Equivalent function silc_client_save_channel_key added into
6040 client.[ch] into client library.
6042 * Changed JOIN command reply to send information whether the channel
6043 was created or not (is existing already) and the channel key
6044 payload. Changed protocol specs accordingly.
6046 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6047 the request was sent by ID and not by nickname. Crashed on
6050 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6052 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6053 now correctly save the received data.
6055 * silc_server_free_sock_user_data now notifies routers in the
6056 network about entities leaving the network.
6058 At the same time implemented functions silc_server_remove_id
6059 and silc_server_send_remove_id to receive and send REMOVE_ID
6060 packets. The packet is used to notify routers in the network
6061 about leaving entities. The ID removed will become invalid in
6064 * Added function silc_idlist_del_server into server. Removes and
6065 free's server entry from ID list.
6067 * silc_server_private_message function now checks, if we are router,
6068 that the destination ID really is valid ID, naturally.
6070 * In router when NEW_ID packet is received (for new client) the
6071 hash of the Client ID is saved in the ID Cache but the
6072 client->nickname is set to NULL, instead of putting the hash
6075 IDENTIFY command now also checks that client->nickname must be
6076 valid. If it is not if will request the data from the server who
6077 owns the client. Added new function
6078 silc_server_command_identify_check.
6080 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6081 to set the command to already allocated Command Payload.
6083 * Tested private message sending in router environment with two
6084 routers, two servers and two clients. Fixed minor bugs and now
6087 * Fixed segfault from client's NAMES command. Used to crash if
6090 * Forwarded packets must not be routed even if it is not destined
6091 to the receiver. Changed server code comply with this.
6093 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6095 * Added `require_reverse_mapping' boolean value to ServerParams
6096 structure. If TRUE (not default) the server will require that
6097 the connecting host has fully qualified domain name.
6099 If the reverse mapping is not required and hostname could not be
6100 found the IP address is used as hostname.
6102 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6104 * Implemented version string checking to both client and server.
6105 The check is incomplete currently due to the abnormal version
6106 strings used in development version of SILC.
6108 * Changed all command functions in server to use the new
6111 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6113 * Changed char *data to unsigned char *data in ID Cache system to
6114 support binary data as ID Cache data. Changed code to support
6115 binary data in lib/silccore/idcache.c.
6117 * Renamed silc_server_packet_relay_command_reply to
6118 silc_server_command_reply as it is normal packet receiving
6119 function. Rewrote the function to accept command replys for
6120 servers and not only for clients.
6122 * Mark remote router always as registered server if we are connecting
6123 to it. Otherwise, commands sent by the router to us are ignored.
6125 * All ID List find routines now returns the ID Cache Entry pointer
6126 as well if requested.
6128 * WHOIS command works now in router environment, tested with two
6129 routers, two servers and two clients.
6131 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6132 in router environment (as it is almost equivalent to WHOIS) but
6133 hasn't been tested thoroughly. Added new functions:
6135 silc_server_command_identify_parse
6136 silc_server_command_identify_send_reply
6137 silc_server_command_identify_from_client
6138 silc_server_command_identify_from_server
6140 * Disabled route cache adding because adding two different ID's with
6141 same IP replaces the old cache entry thus giving wrong route.
6142 The entry->router->connection is always the fastest route anyway
6143 so route cache may not be needed. Of course, new routes maybe
6144 established after receiving the ID when the entry->router->connection
6145 might not be anymore the most optimal.
6147 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6149 * Add route cache for received ID for fast routing.
6151 * Added silc_server_packet_route to route received packet on router
6152 that is not destined to us.
6154 * Renamed silc_server_get_route to silc_server_route_get.
6156 * Added id_string and id_string_len fields into SilcServer to
6157 include encoded ServerID for fast comparing without excess
6158 encoding of the ID's.
6160 * Cleaned up WHOIS command on server side. Added following static
6163 silc_server_command_whois_parse
6164 silc_server_command_whois_check
6165 silc_server_command_whois_send_reply
6166 silc_server_command_whois_from_client
6167 silc_server_command_whois_from_server
6169 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6170 arguments in command replies. All command functions should be
6171 updated to use this macro.
6173 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6175 * Minor typo fixes on command reply handling on server.
6177 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6179 * Added silc_server_command_add_to_channel internal routine to add
6180 the client to the channel after router has created the channel and
6181 sent command reply to the server.
6183 * Added generic silc_server_send_command to send any command from
6186 * Use static buffer with ID rendering instead of duplicating data.
6188 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6190 * Fixed a channel user mode bug when joining to a channel server gave
6191 everybody channel founder rights, oops.
6193 * We mark ourselves as the router of the incoming server connection
6194 if we are router ourselves. This way we can check in some packet
6195 sending functions whether it is locally connected server. For
6196 incoming router connections we put NULL.
6198 * For router sending packets locally means now always sending the
6199 packet cell wide; to local clients and local servers. For normal
6200 server sending packet locally means sending it to only local
6203 * Fixed the JOIN command to really work in router environment. If the
6204 channel is created it is always created by the router. Router is
6205 also responsible of making the initial joining to the channel,
6206 sending JOIN notify to the sending server and distributing
6207 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6208 does not exist server doesn't do anything else but forward the
6209 command to the router which performs everything.
6211 * Added silc_server_send_channel_key function to send the Channel Key
6214 * Added silc_server_create_channel_key to create new channel key. The
6215 channel key is now re-generated everytime someone joins or leaves
6216 a channel, as protocol dictates. Note: channel->key_len is the
6219 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6221 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6222 packet_receive.[ch] to separate packet sending and receiving
6223 routines. The server.[ch] now includes everything else including
6224 actual packet processing (writing and reading data) and other
6227 Renamed silc_server_private_message_send_internal to
6228 silc_server_send_private_message. The routine is still though
6229 used only to relay private messages as server does not send
6230 private messages itself.
6232 Renamed silc_server_new_channel to silc_server_create_new_channel
6233 and added new function sicl_server_new_channel that handles the
6234 incoming New Channel packet. Added also new sending function
6235 silc_server_send_new_channel to send New Channel Payload.
6237 * Added new function silc_server_notify to process incoming notify
6238 packet to the server/router. Server may then relay the notify
6239 to clients if needed.
6241 * Added new function silc_server_new_channel_user to process incoming
6242 New Channel User packet. Router will redistribute the packet and
6243 send JOIN notify to its local clients and locally connected servers
6244 if needed. Normal server will send JOIN notify to its local client
6245 on same channel when received this packet. Added also corresponding
6246 sending function silc_server_send_new_channel_user to sent the
6249 * Added boolean route argument to send_notif_to_channel and
6250 packet_send_to_channel functions to attempt to route the packet
6251 if it is TRUE and send only locally if it is FALSE.
6253 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6255 * silc_server_replace_id now broadcasts the received replace ID
6256 packet if it is not broadcast packet already. The router must
6257 broadcast to inform other routers about changed ID.
6259 * Added backpointer to server's router into SilcServer context in
6260 silcd/server_internal.h.
6262 * Fixed silc_server_packet_broadcast to send correct broadcast
6265 * The channel key is now distributed to the local client as soon
6266 as it is received from the router (in router environment) so that
6267 no other packet may be sent for the channel until client has
6270 * silc_server_remove_channel_user now broadcasts the received
6271 Remove Channel User packet if it is not broadcast packet already.
6272 The router must broadcast to inform other routers about removed
6275 * Added users field into SilcPacketContext that is a reference count
6276 of the context. One can increase the reference count by calling
6277 silc_packet_context_dup which is now changed to just increase the
6278 reference count instead of duplicating the data. The reference
6279 count is decresed by calling silc_packet_context_free that will
6280 free the data after the reference count hits zero.
6282 For now on the packet context and everything allocated into it
6283 (including the raw packet from network) must be freed by calling
6284 the new silc_packet_context_free function. Added also new function
6285 silc_packet_context_alloc that must be used now to allocate the
6286 context. This also means that if a routine is asynchronous from
6287 silc_[client/server]_packet_parse_type the packet context must
6288 be duplicated by calling silc_packet_context_dup. Otherwise it
6289 gets free'd after silc_[client/server]_packet_parse_type returns.
6290 Also, one must remember that if packet is duplicated then its
6291 reference count must be decresed by calling the free function as
6292 many times as it was duplicated.
6294 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6295 from both client and server.
6297 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6299 * Made joining to a channel working in router environment.
6301 * Cleaned up JOIN command on server side and create function
6302 silc_server_command_join_channel internal routine to make the
6305 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6307 * Changed silc_command_pending list to SilcDList. Also, added
6308 `ident' field to SilcServerCommandPending structure to identify
6309 the reply and to call correct callback.
6311 Added silc_server_command_pending_check function to replace the
6312 corresnponding macro. The silc_command_pending list is not
6315 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6316 to set identifier to previously allocated Command Payload. It
6317 is used to set identifier for command when resending Command
6320 * Added silc_command_payload_encode_payload to encode Command
6321 Payload buffer from SilcCommandPayload structure.
6323 * Added silc_argument_payload_encode_payload to encode Argument
6324 payload buffer from SilcArgumentPayload structure.
6326 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6328 * Changed WHOIS command to support router connection on server side.
6329 The whois request is always sent to router unless the server is
6330 standalone server. After server has received the reply from the
6331 router will it send the reply to the client.
6333 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6334 broadcast received broadcast packet. The function is used only
6335 by router. The broadcast packet is always sent to the router's
6338 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6339 render given ID to printable string, for log files for example.
6341 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6343 * Made basic router to router connections working. At least they
6344 can now connect to each other but nothing really works the way
6345 they are supposed - yet.
6347 * Added new initiator token to RouterConnection configuration
6348 file in silcd/serverconfig.[ch]. It is used to tell whether we
6349 are the initiator to the remote router or whether we'll expect
6350 the other end to connect.
6352 * Moved registering of listener task to silc_server_init, hence
6353 the server starts listenning as soon as it is run, even if it
6354 does not have connections to other routers. Let's see how well
6357 * Changed default connection retry timeouts for more suitable in
6360 * Removed cipher and such arguments from silc_idlist_add_client
6361 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6362 Added new function silc_idlist_add_data to add the keys and stuff
6365 * Added SilcIDListData structure and added it to SilcClientEntry
6366 and SilcServerEntry as their first field in the structure. This
6367 way we can explicitly cast the ID entries to the SilcIDListData
6368 structure and get common data for the entries. In past, we had
6369 to first check what type of connection it is and then cast it to
6370 correct ID entry type. Now, we can directly cast the opaque
6371 pointer to the SilcIDListData (no matter what ID entry it actually
6372 is) and get the data needed.
6374 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6376 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6377 in some circumstances even if threre were timeout tasks, though not
6378 IO tasks, but tasks anyway. Now fixed.
6380 * Defined SilcServerConnection structure to hold connection specific
6381 stuff about directly connected servers and routers. The definition
6382 is currently in silcd/server_internal.h. I thought about having
6383 a bit more important role fro this struct but for now it is used
6384 only when connecting to other server (or router actually).
6386 * Added connecting retry support in server when connecting to
6387 router(s). The retry feature implement exponential backoff
6388 algorithm. Also, added SilcServerParams structure to hold default
6389 parameters for server. For now, it include these retry settings
6390 and are hard coded. After server is moded to be as Silc Server
6391 Library this structure will be more important.
6393 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6395 * Changed client librarys channel->clients table to SilcList and
6396 changed code accordingly.
6398 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6400 * Changed client's channel table to SilcList and changed code
6401 accordingly. Also changed SilcChannelClientEntry to include back-
6402 pointer to the channel so that client entry can use that structure
6403 as list as well and we have fast cross-reference to the channel.
6404 This change dramatically decreased the complexity of channel
6405 handling with client entry and vice versa (removed one extra
6406 loop when searching for channel entry from many functions).
6408 * Changed server->sim from table to SilcDList and changed code
6411 * NAMES command can now be used from user interface. It will show
6412 the user list on the channel, neatly.
6414 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6415 Code now saves realname of the user if it becomes available.
6417 * Renamed configure.in to configure.in.pre and made ./prepare
6418 script to automatically add correct version string to
6419 configure.in which it creates from configure.in.pre.
6421 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6423 * NAMES command reply now shows users mode with the nickname when
6426 * Moved silc_client_ch[u]mode[_char] functions from
6427 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6428 place sucks, they are utility functions and should be in some
6431 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6433 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6436 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6440 * Added TRQ (efficient deque and list library) into lib/trq. This is
6441 a very good list library that is currently used in the SILC. Defined
6442 SilcList API over the library because I didn't like the API very
6443 much. See lib/trq/silclist.h for the API and examples of how to
6444 use the API. Fixed various places in the code to use the new
6445 SilcList API. The SilcList is meant for lists that has a structure
6446 already defined as a list. It is not suitable to add just some
6447 context to the list (in TRQ, the context is the list actually).
6449 So, I defined SilcDList that can be used for the purpose where
6450 predefined list structure does not exit. This can be used as
6451 such list. Now some context just can be added to the SilcDList.
6452 Currently this list is not used in the SILC just yet, though there
6453 are a lot places where this can replace dynamically allocated
6454 tables and I will fix these places, later, to use SilcDList.
6455 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6456 and use TRQ internally).
6458 Also fixed some annoying warning messages that the original TRQ
6459 code generated. Also minor changes to TRQ's Makefile.in.
6461 * Added support for querying by Client ID to both WHOIS and
6462 IDENTIFY commands into server, as required by the protocol.
6464 * Removed method function pointers from SilcBuffer structure. They
6465 weren't used to anything and just increased the context size for
6466 no good reason. This change also made silc_buffer_alloc and
6467 silc_buffer_free functions inline functions.
6469 * Disabled command flooding detection support until it's fixed so
6470 that it accepts commands in but does not execute them more than once
6473 * Added silc_net_localhost(), to return local hostname, into
6474 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6475 that must be initialized before calling silc_client_init.
6477 * Added new function: silc_server_send_notify_on_channels to send
6478 notify messages to all channels client has joined. It is assured
6479 that the message is sent only once per client.
6481 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6482 lib/silcutil/silcutil.[ch] as silc_format function. The new
6483 function is generic and is used by server as well, not only by
6484 the logging routines.
6486 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6487 the provided version string was not acceptable. Added new function:
6488 silc_ske_check_version into lib/silcske/silcske.h. The function
6489 must be implemented by the application (client or server) and it
6490 does not reside in the SKE library. The function checks the version
6491 string remote end sent.
6493 * Added back pointers (to opaque context and to SilcSocketConnection)
6494 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6496 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6497 duplicate packet context structure.
6499 * Changed `notify' client operation to send same arguments as client
6500 receives from server except for ID's. ID's are mapped to correct
6501 ID entry and that is returned. Also, if channel entry is not sent
6502 by server but the notify is for channel the channel entry is sent
6503 to application (otherwise application doesn't know that it is for
6504 channel (library gets it from packet's Destination ID)).
6506 * Added silc_client_remove_from_channels into client library to
6507 remove a client from all channels it has joined to. Used when
6508 received SIGNOFF notify from server. Added also new function
6509 silc_client_replace_from_channels to replace old ID entry with
6510 new ID entry on all channels. Used when received NICK_CHANGE
6513 * Fixed ID Cache list handling in silc_idlist_get_client in
6514 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6515 to get (or query) client by ID.
6517 * Updated TODO list.
6519 * Added connection authentication status message defined by the
6520 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6521 support for these into the code in client and server side.
6523 * Added generic function silc_client_send_command to send any command
6524 with variable argument list. Application should use this function
6525 to send commands if the command functions provided by the library
6526 does not suite for the application's user interface needs.
6528 * Added new `failure' client operation. Application is notified about
6529 received failure packet if client is executing a protocol. In this
6530 case the protocol's execution has failed.
6532 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6533 is required by the protocol.
6535 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6536 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6539 * Added status flag to SilcSKE object to indicate realtime status
6540 of the SKE protocol.
6542 * Application receives now exactly same command reply arguments as
6543 the library receives from server. However, if ID is received the
6544 corresponding ID entry is returned to the application (eg. Client
6545 ID is mapped to correct SilcClientEntry entry and that is returned).
6546 Changed command_reply client operation due to this change.
6548 * Changed all ID's in commands and in command replys as ID Payloads.
6549 Change affected both client and server side codes.
6551 All ID's sent in SILC network (with execption of ID's in SILC
6552 Packet header) are sent in ID Payload to support variable length
6555 * Server now notifies nick changes and notifies all clients on
6556 the channels about the new nickname (about the new Client ID,
6559 * Implemented CMODE command to change channel modes. Supports all
6560 channel modes defined by the protocol specs except ban and invite
6561 lists. (Also, private channel key mode is supported but support for
6562 setting private channel key in client is missing, thus, this mode
6563 has no effect on client side (except that server requires that the
6564 client uses private channel key and normal channel traffic does not
6567 Also, invite mode works per se, but INVITE command does not work
6568 yet correctly, so you can set channel as invite only channel but
6569 inviting clients to the channel does not work (it is yet to be
6570 thought what's the best way to do it).
6572 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6573 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6574 Implemented CUMODE command to change user's mode on the channel.
6575 Supports all modes defined by the protocol specs.
6577 * Added NAMES command reply to return users modes on the channel.
6579 * Removed unnecessary and slow ciphers from lib/silccrypt.
6581 * Set SO_KEEPALIVE option to connection sockets by default.
6583 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6585 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6586 redefined the Notify Payload into protocol specs.
6588 * Added silc_id_payload_parse_id to get ID directly from raw
6591 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6593 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6594 accept searching by Client ID as well.
6596 * Added support for LEAVE and SIGNOFF notify types in client library.
6598 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6599 to parse ID Payload from raw data.
6601 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6603 * Added flags parameter into silc_ske_assemble_security_properties
6604 function in lib/silcske/silcske.[ch].
6606 * Changed notify client operation to fit better for notify messages
6607 sent by server. The notify payload received from server is now
6608 passed to the application (after parsing it to SilcNotifyPayload).
6609 It is application's responsibility to retrieve the arguments
6610 from the payload and show the message the way it wants. The message
6611 sent by server is implementation specific.
6613 * Changed public keys to comply with the protocol specification.
6614 Old public keys are not supported anymore and are not compatible.
6616 * Removed nickname from Channel Payload as the latest draft removed
6617 it. The client must resolve the nickname from the NAMES command
6618 reply received when it joined the channel.
6620 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6622 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6624 * Fixed some errors in protocol specification drafts.
6626 * Created lib/silccore/silcnotify.c to implement Notify Payload
6627 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6628 generic payloads described by protocol specifications. The file
6629 includes implementations for ID Payload and Argument Payload.
6631 * Changed Command Payload implementation to use the new Argument
6632 Payload. Changed command_xxxx_payload to command_payload_xxxx
6633 to comply with SILC coding conventions.
6635 * Added suppport for Argument Payload handling in Notify Payload
6636 implementation as protocol requires it. Added the new support
6637 into server and client lib as well.
6639 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6641 * Added support for multiple nicknames on same channel. [n] is
6642 added locally to the nickname if there are more than one same
6643 nicknames on the channel.
6645 * Server now sends all nicknames that matched WHOIS request.
6646 Client also shows the list received from server.
6648 * Added TOPIC command to client side. User can now set and show
6649 current topic on channel.
6651 * Added MOTD command to client and server. Also, server sends the
6652 motd when client connects to the server.
6654 * Changed version strings to comply ISO 8601.
6656 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6658 * Fixed protocol error handling in client library. It should now
6659 cope even if the SKE fails for some reason.
6661 * Made new protocol specification drafts for submitting to IETF.
6663 * Implemented TOPIC command to server in silcd/command.c.
6665 * Added two new notify types into lib/silccore/silcnotify.h:
6666 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6667 notify nickname change and topic setting/change on a channel.
6669 * API change of command_reply operation in client library. The
6670 application gets now the status type received from server as well.
6672 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6674 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6676 * Cras fixed and optimized the packet handling even further and
6677 it should work now. Minor change to the prototype of function
6678 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6680 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6682 * Added new function into lib/silcutil/silcschedule.[ch]:
6683 silc_schedule_with_fd to select() a specified fd. The function
6684 returns after timeout expires or data arrives or goes. The
6685 function is used by packet routines to wait that all data is
6686 received from network.
6688 * Fixed data reading from network in lib/silccore/silcpacket.c.
6689 The code now assures that all data is read from the fd and then
6690 continues packet processing. This was a bug fix since the code
6691 used to drop some data in some circumstances.
6693 * Added new function into lib/silcclient/client.[ch]:
6694 silc_client_start_key_exchange to start key exchange after
6695 connection has been established to server. The code internally
6696 now uses this funtion but its main purpose was to provide it
6697 for applications that perform their own connecting. After
6698 application has created a connection it merely calls this
6699 function to start the key exchange between client and server.
6700 The library takes care of everything else after that.
6702 Updated also lib/silcclient/README to explain the usage of
6705 * Do not send to application information that connection has
6706 been established. Application gets notified it by connect
6709 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6711 * Applied cras's patch to add silc_schedule_one function. The
6712 function runs scheduler once and returns.
6714 * Fixed the scheduler after cras messed it up. The timeout
6715 handling works now as it's supposed to work.
6717 * Added into lib/silccore/ silcnotify.h to include notify
6718 message types support. Changed silc_server_send_notify*
6719 functions, in server.[ch], to support those new notify types.
6720 Added the support for the notify types into client library,
6721 as well. Added new notify client operation into ops.h in
6724 * Changed silc_server_packet_send_to_channel to send normal
6725 packets instead of just channel message packets. The function
6726 is now used to send the notify packets to channels. It is not
6727 used to send channel message packets anymore, as server never
6730 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6731 va_arg()s as it seems to require it nowadays. I guess, if SILC
6732 is compiled with older va_arg() the new code should work anyway.
6734 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6736 * Splitted core library. Core library (lib/silccore) includes
6737 now only SILC protocol specific core (and common) components.
6738 Created new utility library (lib/silcutil) that includes more
6739 generic purpose stuff. The stuff for util library was taken
6740 from the old core library. This was minor and easy split.
6742 * Created SILC Client Library (lib/silcclient) that includes
6743 implementation of the SILC client without user interface. This
6744 was major move from silc/ directory. The code has been changed
6745 so that it is transparent towards the user interface. The
6746 silc/ directory includes now the same user interface as before
6747 and it uses the new client library. Read lib/silcclient/README.
6748 Basicly, the client library performs everything else related
6749 to SILC except user interface handling. Also, configuration
6750 files are considered to be part of user interface and library
6751 does not handle them.
6753 This change also changed a lot of structures, function naming etc.
6754 Most important change was that SilcClientWindow object was
6755 renamed to SilcClientConnection in the client library. Created
6756 also new file lib/silcclient/ops.h. Also added new files
6757 silc/local_command.[ch] and silc/client_ops.[ch].
6759 All these changes were made to make it easier for user interface
6760 designers to create what ever user interface for the SILC client
6763 It is also expected that the server will be moved to lib
6764 directory as well and SILC Server Library will be created;
6765 sometimes in the future.
6767 * Removed Local commands from lib/silccore/silccommand.h as
6768 they are application specific and new client library does not
6769 handle any of those anymore.
6771 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6772 old client implementation in silc/.
6774 * Added support for callback functions in SILC_LOG_* macros.
6775 Application can now set its own callbacks that will be called
6776 instead of using the default functions that will always print
6777 the debug messages to stderr (or stdout). Also, debugging can
6778 now be disabled by setting silc_debug to FALSE and re-enabled by
6779 setting it to TRUE. Note, that logging will still work even
6780 if debugging is disabled.
6782 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6783 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6784 silc_log_reset_debug_callbacks.
6786 * To enable debugging in silc client one must give now -d
6787 option on command line.
6789 * Changed silc_schedule_init to automatically allocate task queues
6790 if they are not allocated before calling it.
6792 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6794 * Added GMP 3.1 into math library.
6796 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6798 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6799 a channel in SILC network. The packet is used by servers and
6800 routers to notify other routers that user has left a channel.
6801 This little feature was missing until now. Added the feature
6802 to protocol specification as well.
6804 Added functions: silc_server_send_remove_channel_user and
6805 silc_server_remove_channel_user into server.[ch].
6807 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6808 lib/silccore/silcpacket.h. However, they are not implemented
6811 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6813 * Fixed joining to a channel and sending channel messages
6814 between server and router. The channel message sending should
6815 now work inside a cell.
6817 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6819 * Fixed the private message sending between server and router.
6820 The private message sending should now work inside a cell.
6822 * Added silc_server_replace_id into server.[ch] to replace
6823 existing ID in the SILC network.
6825 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6826 and silc_idlist_replace_server_id into idlist.[ch] in server.
6828 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6830 * Fixed the server to server connections. Server can again now
6831 connect to router. Router to router connections probably does
6834 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6836 * Added dynamic protocol registering support. Now protocols can
6837 registered and unregistered on the fly. Patch by cras.
6839 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6841 * Added lib/contrib directory to hold routines that some platforms
6842 don't have but are needed by SILC.
6844 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6845 into lin/contrib to provide getopt() and getopt_long() for
6846 those who don't have it.
6848 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6850 * Added AWAY command to client. When away message is set and
6851 client receives a private message packet the client automatically
6852 replies to the sender with the away message.
6854 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6855 bug seemed to be the cause of recent problems when compiling
6858 * Added version detection support to SKE protocol specification
6859 and added the new changes to the SKE implementation as well.
6860 There were other minor changes in the SKE protocol as well.
6862 Many changes in lib/silcske/silcske.[ch] and in
6863 lib/silcske/payload.[ch].
6865 * Added ^U functionality, clear input line. Patch from cras.
6867 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6869 * Mainly small bugfixes on core library. Fixed some debugging
6870 logging and buffer overflow in silclog.c.
6872 * Updated config.sub and config.guess on the distribution tree.
6874 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6876 * Added command lagging support in server. Client may execute
6877 commands now only once in two seconds.
6879 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6881 * Optimized packet reception. MAC computation and checking is now
6882 also more optimized. A lot previously duplicated code is now
6883 used as generic by both client and server.
6885 * Fixed key pair generation in clientutil.c
6887 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6889 * Added into lib/silccore/silcbufutil.[ch] new function;
6890 silc_buffer_realloc.
6892 * Moved generic packet sending/encryption functions to
6893 lib/silccore/silcpacket.[ch] from client and server. Some
6894 rewriting of the functions.
6896 * Moved all generic packet reception/decryption functions to
6897 lib/silccore/silcpacket.[ch] from client and server. The
6898 packet processing is now much cleaner in both client and server.
6899 These were major changes in both client and server.
6901 * Created many common functions in server to do packet sending.
6902 Previously code were duplicated a lot, this has been removed
6905 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6907 * Rewrote major parts of the ID cache system. Don't know
6908 whether it is better now or not but at least the API is more
6911 * Major rewrite on ID cache stuff on client because of the ID
6912 cache API changes. Added idlist.c to client.
6914 * Also major rewrite on ID cache stuff on server as well.
6915 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6916 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6917 in hand, instead they are all put into the ID cache system now.
6918 All server_idlist_* routines uses ID cache now instead of
6919 traversing its own lists (those lists does not exist anymore).
6920 SilcIDList though still exists. Also, SilcXXXEntry's are
6923 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6925 * Finally made the SKE implementation compliant to the protocol
6926 specification. All mp integers are now binary encoded as
6927 opposed being HEX encoded.
6929 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6932 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6933 functions: silc_[encode/decode]_pem. Also added function
6934 silc_encode_pem_file to PEM encode with newlines ('\n') for
6937 * SILC public keys are now encoded either PEM or binary. Same
6938 option is for private keys as well. By default private keys
6939 are binary encoded and public keys PEM encoded. Silly HEX
6940 encoding were removed.
6942 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6943 function to create fingerprints.
6945 * Fixed a bug in SHA1; does not change the original data anymore.
6947 * Partly implemented INFO command on client and server side.
6948 Fixed CLEAR command. Changes to SERVER command; show current
6949 server(s) when giving command without arguments. Added
6950 VERSION command to client.
6952 * Added check to server that unregistered connections cannot
6953 execute commands (unless it is specificly allowed).
6955 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6957 * Fixed screen refresh.
6959 * Fixed channel joining bug from client. On some circumstances
6960 client tried to join to a channel it had already joined.
6962 * Added public key verification process into client's protocol.c.
6963 The client now verifies the public key from user and saves
6964 it into ~./silc/serverkeys/ directory.
6966 Added into: clientutil.[ch]: silc_client_verify_server_key.
6968 * Changed SKE protocol's silc_ske_initiator_finish function
6969 to accept callback function that verifies the received public
6970 key. Removed old silc_ske_verify_public_key function.
6972 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6974 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6975 silc_pkcs_private_key[_data]_set.
6977 * Made the password and public authentication more cleaner in
6978 server's protocol.c.
6980 * Removed historic and obsolete protocol `channel_auth' from
6981 both client and server.
6983 * Removed wrong way of sending command status messages from
6984 server to client in server's command.c. The old way violated
6985 protocol specification.
6987 Changes to silccore/silccommand.[ch]: removed
6988 silc_command_encode_status_payload -> not needed anymore,
6989 changed silc_command_encode_payload_va to accept extra
6990 argument on variable argument list. The argument type must
6991 now be provided to the function. Also, added new function:
6992 silc_command_encode_reply_payload_va which is same as
6993 normal command_encode_payload_va except command status type
6994 is provided as extra argument.
6996 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6998 * Added ~./silc directory handling. The directory includes the
6999 public and private keys for the client.
7001 Added silc_client_check_silc_dir, silc_client_create_identifier
7002 and silc_client_load_keys.
7004 * Implemented SILC protocol compliant public key. Added public
7005 and private key saving to and loading from files.
7007 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
