1 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed CUMODE_CHANGE notify handling to change the mode of
4 correct client. Affected file lib/silcclient/client_notify.c.
6 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
8 * Fixed the file transfer's key agreement payload to include
9 zero port also if the hostname is NULL because it could not
12 Call file transfer monitor callback now also if error occurs
13 during key agreement protocol.
15 Changed the silc_client_file_send interface to return the
16 SilcClientFileError instead of session id. The session ID
17 is returned into pointer provided as argument.
19 Check that the file exists locally before sending the
20 file transfer request at all.
22 Affected file lib/silcclient/client_ftp.c, silcapi.h.
24 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
25 error than can occur while key agreement protocol. Affected
26 file lib/silcclient/silcapi.h.
28 * Fixed the event_mode CMODE handler to not crash when mode
29 is changed and +k mode is set in the channel. Affected file
30 irssi/src/silc/core/silc-channels.c.
32 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
33 SILC_LOG_WARNING to give out Warning and not Error. Affected
34 file lib/silcutil/silclog.c.
36 * Fixed the channel message payload decryption in the function
37 silc_channel_message_payload_decrypt to not modify the original
38 buffer before it is verified that the message decrypted
39 correctly. Otherwise, next time it is called with correct
40 channel key it won't encrypt since the payload is corrupted.
41 Affected file lib/silccore/silcchannel.c.
43 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
45 * Do not constantly resize the window. A fix patch by cras.
46 Affected file irssi/src/fe-text/screen.c.
48 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
50 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
51 Affected file lib/silcutil/silcnet.c.
53 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
55 * Fixed a bug in hash table internal routine for traversing
56 the table with foreach callback. The current entry may
57 become invalid in the callback but it was referenced after
58 the callback returned.
60 Do not allow auto rehashing of hash table during the
61 silc_hash_table_foreach operation, for same reasons as it is
62 not allowed for SilcHashTableList. Affected files are
63 lib/silcutil/silchashtable.[ch].
65 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
67 * Defined DLLAPI into silcincludes.h and silcwin32.h for
68 Win32 DLL. extern's in header files are now declared with
71 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
73 * Fixed private message handling. It used some old code that
74 caused the client to crash. Affecte file is
75 lib/silcclient/client_prvmsg.c.
77 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
79 * Added function silc_client_add_channel,
80 silc_client_replace_channel_id, and removed functions
81 silc_client_new_channel_id and silc_idlist_get_channel_by_id
84 * Added cross reference of the joined channels to the
85 SilcClientEntry, and changed the SilcChannelEntry's
86 users list to SilcHashTable. The affected files are
87 lib/silcclient/idlist.[ch].
89 * Fixed a bug in hash table tarversing. While the hash table
90 is traversed with SilcHashTableList the table must not be
91 rehashed. It is now guaranteed that auto rehashable tables
92 are not rehashed while tarversing the list. Also defined that
93 silc_hash_table_rehash must not be called while tarversing
94 the table. Added function silc_hash_table_list_reset that must
95 be called after the tarversing is over. The affected files are
96 lib/silcutil/silchashtable.[ch].
98 * Changed all hash table traversing to call the new
99 silc_hash_table_list_reset in server and in client library.
101 * Added function silc_client_on_channel to return the
102 SilcChannelUser entry if the specified client entry is joined
103 on the specified channel. This is exported to application as
104 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
106 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
108 * Fixed founder regaining problem with JOIN command on normal
109 server. The notify for mode change must be sent always and
110 not only if !cmd->pending. Affected file silcd/command.c.
112 * Fixed the WHOWAS command's reply sending to support the
113 lists correctly. Affected file silcd/command.c.
115 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
117 * When sending JOIN command to router for processing the
118 sender's old command identifier was not saved back to the
119 sender's command context, fixed now. The affected file is
122 * Create the key in JOIN command of the router did not return
123 the channel key, added check for this. Affected file is
126 * Fixed a channel ID update bug in JOIN command reply. Do
127 not directly upgrade the ID but call the function
128 silc_idlist_replace_channel_id if the ID was changed.
129 Affected file silcd/command_reply.c.
131 * Fixed memory leaks from command calling if it would fail.
132 Affected file silcd/command.c.
134 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
136 * Applied patches from cras:
138 Memory leak fixes around libaries, irssi window resize fix,
139 new silclist.h and silcdlist.h, all extern inline changed to
142 * Removed dotconf from lib/dotconf, not needed anymore.
144 * Removed TRQ from lib/trq, not needed anymore.
146 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
147 with server connections. Later this will be configurable
148 in config file after new config file is done. Affected file
151 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
153 * Fixed a crash in server related to channel announcements.
154 Affected file silcd/server.c.
156 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
158 * Fixed memory leaks in silc_server_create_new_channel*
159 functions. Affected file silcd/server.c.
161 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
162 which ID was changed. This way the router will send the
163 user list for the channel again, and server won't be in
164 desync in some rare circumstances. Affected file is
165 silcd/packet_receive.c.
167 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
169 * Check for NULL socket pointer in the function
170 silc_server_packet_send_to_channel_real. Affected file
173 * Fixed the BAN notify handling to correctly remove ban
174 list. Affected file silcd/packet_receive.c.
176 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
178 * Fixed some header addition to Toolkit distribution in
179 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
181 * Added lib/silcclient/client_ops_example.h as an template
182 file for application programmers to quickly start using
183 the SilcClientOperation functions in their application.
184 Updated the lib/silcclient/README as well to tell about this
185 nice file made available.
187 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
189 * Call silc_server_remove_from_channels when removing client
190 entry when NO_SUCH_CLIENT_ID was received. Affected file
191 is silcd/command_reply.c.
193 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
195 * Added server & router operator statistics updating. Affected
196 file silcd/packet_receive.c and silcd/command.c.
198 * Fixed the SERVER_SIGNOFF notify handling on normal server
199 not to save the history information for clients. Same was
200 fixed earlier in remove_clients_by_server function, but not
201 here. Affected file silcd/packet_receive.c.
203 * Raised the default connection-retry count from 4 to 7 in
204 server. Affected file silcd/server.h.
206 * Cancel any possible reconnect timeouts when we start the
207 key exchange. Affected file silcd/server.c.
209 * Do not reconnect on connection failure when SCONNECT was
210 given. Affected files silcd/server.[ch].
212 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
214 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
216 * Fixed the NICK command to always give the unformatted
217 nickname to the one giving the NICK command. If unformatted
218 nickname is cached already it will be formatted and the
219 local entry will always get the unformatted nickname.
220 Affected file lib/silcclient/idlist.c.
222 * Fixed some double frees from client library commands.
223 Affected file is lib/silcclient/command.c.
225 * Fixed CUMODE command in server to assure that no one can
226 change founder's mode than the founder itself, there was a
227 little bug. Affected file silcd/command.c.
229 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
231 * Removed the SilcClientCommandDestructor from the client
232 libary, it is not needed anymore. Affected files are
233 lib/silcclient/silcapi.h, command[_reply].[ch],
234 client_notify, idlist.c.
236 * Fixed GETKEY command to first resolve client, and then
237 resolve the server only if the client was not found, instead
238 of resolving both at the same time. Affected file is
239 lib/silcclient/command.c.
241 * Added silc_client_start_key_exchange_cb and lookup the
242 remote hostname and IP address before starting the key
243 exchange with server. The affected file is
244 lib/silcclient/client.c.
246 * The server's public key is now saved using the IP address
247 of the server and not the servername for the filename.
248 The hostname public key filename is checked as an fall back
249 method if the IP address based filename is not found.
251 Fixed the GETKEY command to save the fetched server key
254 Print the remote server's hostname now when new key is
255 received during connection process. Affected file is
256 irssi/src/silc/core/client_ops.c.
258 * Return always our own public key to the client if it asks
259 for it with GETKEY command. Affected file silcd/command.c.
261 * Removed the use_auto_addr variable from default config
262 file since it was in wrong section. Affected file is
265 * Fixed TOPIC_CHANGE notification to not route it when it
266 was sent using silc_server_send_notify_to_channel function.
267 Affected file silcd/command.c.
269 * Fixed silc_server_send_notify_kicked to send the kicker's
270 Client ID also, it was missing. Affected files are
271 silcd/command.c, silcd/packet_send.[ch].
273 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
275 * Do not save client history information in SERVER_SIGNOFF.
276 Fixes the bug in normal server that it does not detect
277 the client becoming valid after the server becomes back
278 online. Affected file silcd/server_util.c.
280 * Added `sock_error' field into the SilcSocketConnection
281 context. When error occurs during socket operation (read
282 or write) the error is saved. Added also new function
283 silc_socket_get_error to return human readable socket error
284 message. Affected files are lib/silcutil/silcsockconn.[ch],
285 lib/silcutil/unix/silcunixsockconn.c, and
286 lib/silcutil/win32/silcwin32sockconn.c.
288 * The server now prints the socket error message in the
289 signoff for client. Affected file silcd/server.c.
291 * Fixed the `created' channel information sending from router
292 to server in JOIN command. Checks now whether the channel
293 really was created or not and set it according that.
295 Fixed the JOIN command to use the client entry's current
296 ID during the joining procedure instead of the one it sent
297 in the command (it is checked though), since it can change
298 between the packet processing and command processing, and
299 would just case unnecessary pain in the client end. Affected
300 file silcd/command.c.
302 * Fixed a channel key payload sending to use correct channel
303 ID when the server was forced to change the channel's ID by
304 router. Router sent the key payload with the old Channel ID.
305 Affected file silcd/packet_receive.c.
307 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
309 * Call silc_server_save_channel_key only if the key payload
310 was provided in the JOIN command's command reply. Affected
311 file silcd/command_reply.c.
313 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
315 * Fixed silc_mp_sizeinbase to return the value correctly with
316 MPI. Affected file lib/silcmath/mp_mpi.c.
318 * Fixed the stop_server signal to correctly stop the scheduler
319 and gracefully stop the server when SIGTERM or SIGINT signals
320 are received. Affected file silcd/silcd.c.
322 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
324 * Simple handling of TERM and HUP signals. Also added some log
325 flushing call around. Affected file is
328 * Fixed small bugs in silclog.c. Now buffering output will take
329 effect after 10 seconds since startup: This will ensure that
330 no important startup messages are lost. Also output redirection
331 will preserve original format ([Date] [Type] message).
332 Affected file is lib/silcutil/silclog.c.
334 * Added two options to the config file, in the logging section:
335 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
336 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
338 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
340 * Do not print the warning about log files not being initialized
341 more than once to avoid excess logging. Affected file is
342 lib/silcutil/silclog.c.
344 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
345 the SIM copying in make install in Makefile.am.pre.
347 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
349 * Rewritten silclog APIs. Globally interesting changes follows:
350 silc_log_set_files() changed to silc_log_set_file().
351 silc_log_set_callbacks() changed to silc_log_set_callback().
352 ROBOdoc documented silclog header file.
353 SilcLogCb now returns bool to wether inihibit the default
354 handler or not (to keep the old behaviour return always TRUE).
355 The new APIs should also fix the problem of the
356 silcd_error.log file that was written in the current directory.
359 Log files streams will remain opened after silc_log_set_file()
360 call, means less CPU usage notably on high traffic servers.
361 File streams are now full buffered, and flushed to the disk
362 every 5 minutes, lesses HD activity and CPU usage.
363 Messages can be redirected, allowing admins to configure
364 one single logfile for all server messages.
365 the silc_log_quick global variable to activate fast-logging.
366 Affected files lib/silcutil/silclog.[ch]
368 * Changed some code to conform new silclog APIs. Affected
369 files are doc/example_silcd.conf.in, silcd/server.c
370 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
373 * Fixed a memory leak that could occur in some situations.
374 Affected file silcd/serverconfig.c.
376 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
378 * Added the silc_client_del_client to remove the client from
379 all channels as well. Affected file lib/silcclient/idlist.c.
381 * Fixed the client library to correctly remove the client
382 from all channels when the client entry is being destroyed.
383 Affected file lib/silcclient/client_notify.c, command.c.
385 * Added auto-nicking support to the client library. If the
386 applicatio now sets client->nickname it will be sent to the
387 server after connecting by the library. This way for example
388 SILCNICK (or IRCNICK) environment variables will have effect
389 and always change the nickname automatically to whatever
390 it is wanted. Affected file lib/silcclient/client.[ch].
392 * Renamed silc_server_command_bad_chars to the
393 silc_server_name_bad_chars and moved it to the
394 silcd/server_util.[ch]. Added also new function
395 silc_server_name_modify_bad to return nickname that
396 includes bad characters as new nickname without those
397 bad characters. This check and modify is now used in
398 silc_server_new_client when the username is initially set
399 as nickname, so it must be checked to be valid nickname.
400 Affected file silcd/packet_receive.c.
402 * The nickname length is now taken from the packet for real
403 and not trusted to strlen() since it clearly can return
404 wrong length for nickname including bad characters. This
405 also applies to channel names. Affected file silcd/command.c.
407 * Removed the lib/silcsilm/modules directory. Modules are now
408 compiled into the lib/silcsim. Fixed the copying of the
409 modules to follow symbolic links in Makefile.am.pre.
411 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
413 * Fixed silc_string_regexify list creation. Fixes bugs with
414 BAN and INVITE commands in server. The affected file is
415 lib/silcutil/unix/silcunixutil.c.
417 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
419 * Removed the command destructor entirely from the server's
420 command and command reply routines. It is not needed, and
421 its usage was buggy and caused crashes. Affected files are
422 silcd/command[_reply].[ch].
424 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
426 * Cancel protocol and NULL sock->protocol if timeout
427 occurred during protocol. Affected file silcd/server.c.
429 * Cancel protocol timeouts always before calling the final
430 callback, to assure that after final callback is called
431 no other state will be called for the protocol anymore.
432 Affected file silcd/protocol.c.
434 * Print error log if incoming connection configuration could
435 not be found. Affected file silcd/server.c.
437 * Fixed JOIN command to correctly save the founder mode
438 to the client on normal SILC server, when the channel
439 was created by the router. Affected file silcd/command.c.
441 * Fixed LIST command (hopefully) to send correct reply
442 packets. Affected file silcd/command.c.
444 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
446 * The silc_packet_receive_process now returns FALSE if the
447 read data was invalid packet, and TRUE if it was ok.
449 The server now checks that if unauthenticated connection
450 sends data and its processing fails the server will close
451 the connection since it could be a malicious flooder.
453 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
455 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
457 * Make sure the warning about error opening a log file is
458 printed only once and not everytime it fails (produces
459 too much useless log). Affected file lib/silcutil/silclog.c.
461 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
463 * Made the silc_server_daemonise() function more readable.
464 Affected file silcd/server.c.
466 * Pid file is now optional, the user may comment it out from
467 the config file. Removed define SILC_SERVER_PID_FILE, we
468 don't need a default any longer. Affected file
469 configure.in.pre, lib/Makefile.am.pre.
471 * Make some use of the pid file. The server now dies at startup
472 if it detects a valid pid file on his path. The server would
473 die anyway in this circumstance, because of the bind() failure.
474 Affected file silcd/silcd.c.
476 * No longer compiling lib/dotconf.
478 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
480 * Fixed JOIN command parsing not to crash. Affected file
481 lib/silcclient/command.c.
483 * Fied the NICK_CHANGE notify to add the new client entry
484 even it is resolved. This removes an <[unknown]> nick
485 thingy bug in the client. Affected file is
486 lib/silcclient/client_notify.c.
488 * Do not try to allocate 0 bytes (efence does not like it)
489 in lib/silccore/silccomand.c when encoding payload.
491 * Do not take IRCNICK as nickname in Irssi SILC client since
492 it is not possible to set nickname before hand connecting
493 the server (TODO has an entry about adding auto-nicking
496 * Changed the silc_server_command_pending to check whether
497 there already exists an pending entry with the specified
498 command, command identifier and pending callback. This is
499 to fix IDENTIFY and WHOIS related crashes that may register
500 multiple pending commands with same identifier. Affected
501 file silcd/command.c.
503 * Fixed the server to reconnect to the router even if it
504 was already reconnecting and EOF was received. This to
505 fix a possibility that the server wouldn't ever try to
506 auto-reconnect to the router. Affected file silcd/server.c.
508 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
510 * Fixed the server's password authentication to use the
511 length of the locally saved password, and not the one
512 sent in the packet. Affected file silcd/protocol.c.
514 * Fixed same password authentication problem in the
515 Authentication Payload handling routines in
516 lib/silccore/silcauth.c.
518 * Yet another password authentication problem fixed with
519 channel password handling in silcd/command.c.
521 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
523 * If first character of string in silc_parse_userfqdn is '@'
524 then do not parse it. Affected file is
525 lib/silcutil/silcutil.c.
527 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
529 * Fixed minor bug in IDENTIFY command reply sending, which
530 caused various weird problems during JOIN when it was
531 resolving names for users. Affected file silcd/command.c.
533 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
535 * Fixed the IDENTIFY command reply sending to chech better valid
536 clients. It was possible to send incomplete list of replies.
537 Affected file silcd/command.c.
539 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
541 * Added silc_client_command[s]_[un]register functions now to
542 dynamically register the commands in client library. Removed
543 the static table of commands. This allows the client library
544 to call commands without causing the application to know about
545 what commands library has called.
547 Removed the INFO command reply kludge to detect when the command
548 was called by library. Now library use its own command reply
549 function for INFO command.
551 Added function silc_client_command_call to call a command.
552 Application can use it to call command, not access the structure
555 Now all commands that are sent by the client library (not
556 explicitly sent by application) use own command reply functions.
558 Affected files around lib/silcclient/ and in
559 irssi/src/silc/core/.
561 * Fixed the WHOIS command reply sending to chech better valid
562 clients. It was possible to send incomplete list of replies.
564 Fixed the WHOIS and IDENTIFY to send the request to router
565 if normal server did not do it and did not find any results.
567 Affected file silcd/command.c.
569 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
571 * Moved the internal data from SilcClient context into its
572 own file, not accesible to application. Affected files
573 lib/silcclient/client.h and lib/silcclient/client_internal.h,
574 and other files in client library.
576 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
578 * Added doc/examples installation target in Makefile.am.pre.
581 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
583 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
584 commands the found client entry will be removed from the
585 cache, after notifying application about the error. Affected
586 file lib/silcclient/command_reply.c.
588 * Changed the /MSG to check for exact nickname user gave, and
589 not let `nick' match `nick@host' if it is only one found. Now,
590 user must type the exact nickname (like nick@host2) even if
591 there are no more than one same nicks found. This is to avoid
592 a possibility of sending nickname to wrong nickname since
593 `nick' could match `nick@host'. Affected file is
594 irssi/src/core/silc-servers.c.
596 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
598 * Do not print "you are now server operator" or similar when
599 giving /away command. Affected files are
600 irssi/src/silc/core/client_ops.c, silc-servers.h.
602 * Made the silc_server_command_pending_error_check to send
603 the same command reply payload it received back to the
604 original sender of the command. This way all arguments
605 that was received by the server will be received by the
606 client too. Affected file silcd/command.c.
608 * Added the silc_idcache_add to return the created cache entry
609 to a pointer. Affected file lib/silccore/silcidcache.[ch].
611 * Add global clients to expire if they are not on any channel.
612 This is because normal server will never know if they signoff
613 if they are not on any channel. The cache expiry will take
614 case of these entries. This is done by normal servers only.
615 The affected files are silcd/command_reply.c,
616 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
618 * If server receives invalid ID notification for WHOIS or
619 IDENTIFY and the ID exists in the lists, it is removed.
620 Affected file silcd/command_reply.c.
622 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
623 in client then client entry that it matches is searched and
624 the nickname is printed on the screen for user. Affected
625 file irssi/src/silc/core/client_ops.c.
627 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
629 * Use cache entry expire time in the LIST command reply to
630 purge old entries from the cache after the LIST command
631 reply has been received. This way we don't have non-existent
632 entries in the cache for too long. Affected file is
633 silcd/command_reply.c.
635 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
637 * If we are normal server, and we've not resolved client info
638 in WHOIS or IDENTIFY from router, and it is global client,
639 we'll check whether it is on some channel. If it is not
640 then we cannot be sure about its validity and will resolve it
641 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
642 file silcd/command.c.
644 * Search channel by name (if possible) rather than by ID
645 in IDENTIFY command's command reply. Affected file is
646 silcd/command_reply.c.
648 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
650 * Distribute to the channel passphrase in CMODE_CHANGE notify.
651 Updated specs and implemented it. Affected file silcd/command.c,
652 silcd/packet_send.c and silcd/packet_receive.c.
654 * Implemented the <founder auth> payload handling in the JOIN
655 command. If provided all conditions for channel joining
656 except requirement to provide correct passphrase can be
657 overrided by the channel founder. Updated the protocol specs.
658 Affected file silcd/command.c.
660 Added support for founder auth in JOIN command in client
661 library. Fixed the parsing of the JOIN command now to support
662 all options as they should be. The affected file is
663 lib/silcclient/command.c.
665 * Optimized the WHOIS and IDENTIFY commands to send the request
666 to router only if it includes nicknames or other names. If
667 they include only IDs then check the local cache first before
668 routing. Affected file is silcd/command.c.
670 * Added channels topic announcements. Affected file is
671 silcd/packet_receive.c and silcd/server.c.
673 * Fixed the silc_server_send_notify_topic_set to really destine
674 the packet to channel. Affected file silcd/packet_send.c.
676 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
677 library. Affected file lib/silcclient/client_notify.c.
679 * Added UMODE announcements. Affected file silcd/server.c.
681 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
683 * Memory leak fixes in:
685 lib/silcutil/silcsockconn.c
686 lib/silcske/silcske.c
689 lib/silccrypt/silcpkcs.c
690 lib/silccore/silccommand.c
691 lib/silccore/silcidcache.c
696 * ROBOdoc documented the lib/silcske/groups.h file and a
697 bit changed the interface for better.
699 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
701 * Update the client entry context in the ID cache after
702 nick change. Affected file lib/silcclient/command.c.
703 Fixes the CUMODE command when regaining founder privileges,
704 and a little WHOIS problem.
706 * Fixed silc_net_gethostbyname to correctly call the
707 inet_ntop. Affected file lib/silcutil/silcnet.c.
709 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
711 * Added IPv6 support checking to the configure.in.pre, added
712 also --enable-ipv6 option to override the check. Affected
713 file configure.in.pre.
715 * The silc_thread_create now calls the start function
716 directly if threads support is not compiled in. Removes
717 ugly #ifdef's from generic code. Affected files are
718 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
720 * Added silc_net_gethostby[name/addr]_async to asynchronously
721 resolve. Affected files are lib/silcutil/silcnet.[ch].
723 * Added support for rendering IPv6 based server, client and
724 channel IDs. Affected file lib/silcutil/silcutil.c.
726 * Added support for creating IPv6 based server IDs. Affected
727 file is silcd/serverid.c.
729 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
731 * Added silc_net_gethostby[addr/name] into the
732 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
733 routines. Added silc_net_is_ip[4/6]. Affected file is
734 lib/silcutil/unix/silcunixnet.c. All routines that take
735 address as argument now supports both IPv4 and IPv6 addresses.
737 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
739 * Fixed LIST command reply sending in server. Affected file
742 * Server now sends the kicker's client ID in the KICK notify
743 to the kicked client. Affected file silcd/command.c.
745 * The client library now parses the kickers client ID and
746 UI displays it. Affected files lib/silcclient/client_notify.c
747 and irssi/src/silc/core/silc-channels.c, module-formats.c.
749 * Made all payload parsing function prototypes consistent.
750 They all take now const unsigned char * and uint32 pair as
751 the payload data instead of SilcBuffer. Changes all around
752 the source tree. Other unsigned char* -> const unsigned char*
753 changes around the tree as well.
755 * Optimized SFTP client and server packet sending not to
756 allocate new buffer for each packet but to recycle the
757 first allocated buffer. Affected files are
758 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
760 * Optimized the SFTP client to use SilcList instead of
761 SilcDList for requests, because it is faster. Affected file
762 is lib/silcsftp/sftp_client.c.
764 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
765 into lib/silccore/silcid.[ch].
767 Renamed silcpayload.[ch] into silcargument.[ch].
769 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
771 * If client entry is deleted with active key agreement
772 session, abort the session.
774 The silc_client_abort_key_agreement now calls the completion
775 callback with new SILC_KEY_AGREEMENT_ABORTED status.
777 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
780 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
782 * Don't use __restrict in older GCC's. Affected file is
783 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
785 * silc_net_localhost now attempts to reverse lookup the
786 IP/hostname. Affected file lib/silcutil/silcnet.c.
788 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
789 command. It can be used to gain founder privileges at
790 the same time when joining the channel.
792 Defined that the SILC_NOTIFY_TYPE_KICKED send the
793 kicker's client ID as well. Updated protocol specs.
795 Defined that the server must send SILC_COMMAND_IDENTIFY
796 command reply with error status to client who sent
797 private message with invalid client ID.
799 Updated the protocol specification.
801 * Added silc_server_send_command_reply to send any
802 command reply. Affected file silcd/packet_send.[ch].
804 * Added silc_id_payload_encode_data to encode ID payload
805 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
807 * The server now send IDENTIFY command reply with error
808 status if client ID in private message is invalid. Affected
809 file silcd/packet_receive.c.
811 * Save the server key file with server's IP address in
812 the filename instead of hostname. The affected file is
813 irssi/src/silc/core/client_ops.c.
815 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
817 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
820 * Added libtool support for compiling shared objects in
821 lib/silcsim. Affected file configure.in.pre and
822 lib/silcsim/Makefile.am. Original patch by cras.
824 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
826 * Pid file configuration, and server's config file fixes
827 patch by toma. Updated CREDITS file.
829 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
831 * Fixed silc_client_channel_message to not try to decrypt
832 the message twice if it resolved the destination client
833 information. This could cause of dropping one channel
834 message. Affected file lib/silcclient/client_channel.c.
836 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
838 * Added silc_client_run_one into lib/silcclient/silcapi.h and
839 lib/silcclient/client.c. This function is used when the SILC
840 Client is run under some other scheduler, or event loop or
841 main loop. On GUI applications, for example this may be
842 desired to used to run the client under the GUI application's
843 main loop. Typically the GUI application would register an
844 idle task that calls this function multiple times in a second
845 to quickly process the SILC specific data.
847 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
849 * Fixed silc_server_drop() for dropping the supplementary
850 groups as well, this could cause a security hole on some
853 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
855 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
858 * Write PID file after dropping privileges. Added -F option
859 to run server on foreground. A patch by debolaz.
860 Affected files silcd/server.c, silcd/silcd.c.
862 * Fixed MOTD to return the MOTD file server name. Affected
863 file silcd/command.c.
865 * Added INFO command reply handling to the Irssi SILC Client.
866 Affected file irssi/src/silc/core/client_ops.c.
868 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
870 * Fixed the silc_idcache_list_* routines to really support
871 the dynamic list. Fixes a crash. Affected file is
872 lib/silccore/silcidcache.c.
874 * Fixed the LIST command reply to really call LIST command's
875 pending callbacks. Affected file silcd/command_reply.c.
877 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
879 * Update conn->local_entry->nickname after giving NICK
880 command. Affected file lib/silcclient/command.c.
882 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
884 * Added the [pid] option to the silcd configuration file
886 Affected files: serverconfig.[ch] and silcd.c
888 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
890 * Save fingerprint in WHOIS command reply in server.
891 Affected file silcd/command_reply.c.
893 * Fixed NICK commands pending callback registration.
894 Affected file lib/silcclient/command.c.
896 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
898 * Use ++server->cmd_ident when sending commands in server,
899 instead of random number. Affected file silcd/command.c.
901 * Fixed GETKEY command reply to call actually GETKEY pending
902 command callbacks. Affected file silcd/command_reply.c.
904 * A bit stricter check for nicknames. Check for same nickname
905 in NICK command also. Affected file silcd/command.c.
907 * Do not call INFO command everytime client ID changes, only
908 during first connecting. Affected file lib/silcclient/client.c.
910 * Set the new nickname only after successful command reply for
911 NICK command is returned by server. Affected file
912 lib/silcclient/command.c.
914 * Remove nicknames from nicklist during server_signoff notify.
915 Should fix /NAMES bit more. The affected file is
916 irssi/src/silc/core/silc-channels.c.
918 * Added `fingerprint' field to the SilcIDListData in the
919 silcd/idlist.h to hold the fingerprint of the client's
922 Send the fingerprint of the client's public key in WHOIS
925 Affected files silcd/command.c, and silcd/idlist.[ch].
927 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
928 create fingerprint from given data.
930 * Show the fingerprint of the client's public key in WHOIS.
931 Affected files irssi/src/module-formats.[ch] and
932 irssi/src/silc/core/client_ops.c.
934 * Format the multiple same nicknames also during JOIN and
935 NICK_CHANGE notifys. Affected file is
936 lib/silcclient/client_notify.c.
938 * Do not print error on screen for invalid private message
939 payload since it can come if someone is sending private
940 messages with wrong key. Affected file
941 lib/silccore/silcprivate.c.
943 * Fixed multiple concurrent /PING crash. Affected file
944 lib/silcclient/command.c.
946 * Changed the wrong ID encoding. All IP addresses must be
947 in MSB first order in encoded format. They were encoded
948 wrong and was in LSB format. Affected files are
949 silcd/serverid.c, lib/silcutil/silcutil.c.
951 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
953 * Call the `connect' client operation through the scheduler
954 in case of error. Affected file lib/silcclient/client.c.
956 * Call the `failure' client operation even if the error
957 occurred locally during a protocol. Affected file is
958 lib/silcclient/protocol.c.
960 * Added support of sending LIST command to router from normal
961 server. This way normal server can get list of all channels
962 in the network too. Fixed the channel list sending in the
963 server too. Affected files are silcd/command.c, and
964 silcd/command_reply.[ch].
966 * Added silc_server_update_channels_by_server and
967 silc_server_remove_channels_by_server. They are used during
968 disconnection of primary router and in backup router protocol.
969 Affected file silcd/server_util.[ch], silcd/server.c and
970 silcd/server_backup.c.
972 * Fixed channel adding to global list in IDENTIFY command
973 reply in server. Affected file silcd/command_reply.c.
975 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
977 * If the incoming packet type is REKEY or REKEY_DONE process
978 that packet always synchronously. Fixes yet another MAC
979 failed error on slow (dialup) connections. Affected file
980 lib/silcclient/client.c and silcd/server.c.
982 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
984 * Call check_version SKE callback for initiator too. Affected
985 file lib/silcske/silcske.c.
987 * Implemented fix for security hole found in the SKE that was
988 fixed in the specification few days back; the initiator's
989 public key is now added to the HASH value computation.
990 Added backwards support for the old way of doing it too, for
991 old clients and old servers. Affected file is
992 lib/silcske/silcske.c.
994 * Enabled mutual authentication by default in SKE. If initiator
995 is not providing mutual authentication the responder will
996 force it. This will provide the proof of posession of the
997 private key for responder. The affected files are
998 lib/silcclient/protocol.c and silcd/protocol.c.
1000 * Do not cache anymore the server's public key during SKE.
1001 We do mutual authentication so the proof of posession of
1002 private key is done, and if the server is authenticated in
1003 conn auth protocol with public key we must have the public
1004 key already. Affected file silcd/protocol.c.
1006 * Added new global debug variable: silc_debug_hexdump. If
1007 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1008 file lib/silcutil/silclog.[ch].
1010 * Fixed compilation warning due to char * -> const char *.
1011 Affected files lib/silcutil/silcnet.h, and
1012 lib/silccore/silcauth.[ch].
1014 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1016 * Fixed CMODE command when new channel key was created. If
1017 the creation failed the old key was removed. Next time giving
1018 same command would crash the server since the old key was
1019 freed already. Affected file silcd/command.c.
1021 * Fixed the silc_server_announce_get_channels to not crash
1022 on reconnect. Affected file silcd/server.c.
1024 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1026 * Added silc_log_set_debug_string function to set a regex
1027 string to match for debug output. Only the function names,
1028 or filenames matching the given debug string is actually
1029 printed. This way it is possible to filter out those debug
1030 strings that user is not interested in.
1032 Fixed a bug in silc_string_regexify.
1034 Affected files lib/silcutil/silclog.[ch], and
1035 lib/silcutil/unix/silcunixutil.c.
1037 * Changed the -d options in both server and Irssi SILC client
1038 to take the debug string as argument. Affected files
1039 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1041 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1043 * Added silc_hash_babbleprint to create a Bubble Babble
1044 Encoded fingerprint. The encoding is developed by Antti
1045 Huima (draft-huima-babble-01.txt), and it creates human
1046 readable strings out of binary data. Affected file
1047 lib/silccrypt/silchash.[ch].
1049 * Print the babble print now in addition of fingerprint as well
1050 in Irssi SILC client. Affected files are
1051 irssi/src/fe-common/silc/module-formats.[ch],
1052 irssi/src/fe-common/silc/core/client_ops.c.
1054 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1056 * Fixed a security problem found in SKE. The initiator's
1057 public key too is now added to the HASH hash value creation
1058 which is signed by the responder to create the SIGN value.
1059 This will prevent anyone in the middle to lie to the responder
1060 about the initiator's public key. If this is done now, the
1061 man in the middle will get caught. Updated the protocol
1064 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1066 * Better installation directory handling. Configure module
1067 paths and other paths automatically to example_silc* files
1068 in doc/. A patch by toma.
1070 * Fixed compiler warning from MPI library, and from SILC RNG.
1073 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1074 It can be configured with ./configure. A patch by toma.
1076 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1078 * Find correct make to use in prepare-clean. A patch by
1079 toma. Affected file prepare-clean.
1081 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1083 * Added irssi variables use_auto_addr, auto_bind_ip,
1084 auto_bind_port and auto_public_ip.
1086 * Changed the interface for silc_client_send_key_agreement
1087 in lib/silcclient/silcapi.h
1091 irssi/src/silc/core/silc-core.c
1093 lib/silcclient/silcapi.h
1094 irssi/src/silc/core/silc-channels.c
1095 lib/silcclient/client_keyagr.c
1098 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1100 * Added silc_pkcs_public_key_compare to compare two
1101 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1103 * Check that the client who set the founder mode on the
1104 channel is the same client that is giving the founder
1105 mode to itself. It is done by comparing the saved public
1106 key (it is saved even in the authentication is passphrase).
1107 Affected file silcd/command.c.
1109 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1111 * Do not process packet for disconnected socket connection.
1112 Affected file lib/silccore/silcpacket.c.
1114 * Process the DISCONNECT packet through scheduler in the
1115 client library. Affected file lib/silcclient/client.c.
1117 * Fixed the silc_client_packet_parse to not to increase
1118 the packet sequence number if the conn->sock and the
1119 current socket connection is not same. This can happen
1120 for example during key agreement when the conn includes
1121 multiple socket connections (listeners). Affected file
1122 lib/silcclient/client.c.
1124 * The sender of the file transfer request now provides also
1125 the pointer (listener) for the key exchange protocol. If
1126 the listener cannot be created then it sends empty key
1127 agreement and lets the receiver provide the listener.
1129 Added `local_ip' and `local_port' arguments to the
1130 silc_client_file_send. If they are provided they are used,
1131 if not then it will attempt to find local IP address, if
1132 not found or bind fails then the remote client will provide
1135 Affected files are lib/silcclient/client_ftp.c and
1136 lib/silcclient/silcapi.h.
1138 * Extended the FILE SEND command to support defining the
1139 local IP and port for key exchange listener. They are

1144 * Defined to WHOIS command reply the sending of fingerprint
1145 of the client's public key (if the proof of posession of the
1146 corresponding private key is verified by the server).
1147 Updated to the protocol specification.
1149 * Added support of receiving the client's public key's
1150 fingerprint in command reply in client library. Affected
1151 file is lib/silcclient/command_reply.c, and
1152 lib/silcclient/idlist.[ch].
1154 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1211 preserve the WHOWAS info for the client. Affected file
1212 silcd/server_util.c.
1214 * Fixed SERVER_SIGNOFF notify handling in the server. The
1215 server is now able to process incoming SERVER_SIGNOFF notify
1216 for a server that it doesn't even know about. It will remove
1217 the clients provided in the notify. Affected file
1218 silcd/packet_receive.c.
1220 * Check for partial packet in data queue after every packet that
1221 was found from the queue. Return and wait for more data if
1222 there is partial data in queue. Affected file is
1223 lib/silccore/silcpacket.c.
1225 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1240 irssi/src/fe-common/silc/module-formats.[ch].
1242 * Wrote a help file for FILE command.
1244 * Added silc_rng_global_get_byte_fast to get not-so-secure
1245 random data as fast as possible. Random data is read from
1246 /dev/urandom if available and from the SILC RNG if not
1247 available. It is used in padding generation. Affected file
1248 lib/silccrypt/silcrng.[ch].
1250 * All packets in client library are now processed synchronously.
1251 Optimized packet processing a lot. Affected file
1252 lib/silcclient/client.c.
1254 * All server connection packets are processing synchronously
1255 now in server, to optimize packet processing. Affected file
1258 * Include files are installed now only in Toolkit distribution
1259 if make install is given. Affected files: all Makefile.am's.
1261 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1263 * Assure that silc_client_notify_by_server_resolve does not
1264 resolve the client information multiple times. If it cannot
1265 be found by the first it cannot be found at all. Affected
1266 file lib/silcclient/client_notify.c.
1268 * Fixed WHOWAS command reply calling. Affected file
1269 lib/silcclient/command_reply.c.
1271 * Removed all references to silc_idlist_get_client from the
1272 Irssi SILC client since that call is internal call used by
1273 the library. The Irssi SILC client will use now client
1274 retrieval functions found in silcapi.h.
1276 * Fixed a bug in resolving nickname info before sending
1277 private message. It used freed memory. Affected file
1278 irssi/src/silc/core/silc-servers.c.
1280 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1282 * Assure my_channels statistics cannot go negative in server.
1283 Affected files silcd/server.c, silcd/server_util.c.

1299 * Added silc_net_localip to return local host's IP address.
1300 Affected file lib/silcutil/silcnet.[ch].
1302 * If key exchange or rekey protocol is active for a connection
1303 parse all packets syncronously since there might be packets
1304 in packet queue that we are not able to process without first
1305 processing packets before them. Affected file silcd/server,
1306 lib/silcclient/client.c.
1308 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1309 whether library should continue processing the packet.
1310 Affected file lib/silccore/silcpacket.h.
1312 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

1341 lib/silcutil/silcutil.[ch].
1343 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1345 * Resolve the client info when received private message or
1346 channel message for a client which nickname we don't know.
1347 Affected files lib/silcclient/client_prvmsg.c and
1348 lib/silcclient/client_channel.c.

1354 lib/silcclient/idlist.h.
1356 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1357 is incomplete and is being resolved, it won't be resolved
1360 Make sure also that USERS command reply does not resolve
1361 twice information. Affected file is
1362 lib/silcclient/command_reply.c.
1364 Make sure that silc_client_get_clients_by_list does not
1365 resolve twice same information.
1367 * Check for valid client->id in the silc_server_free_client_data.
1368 Affected file silcd/server.c.
1370 * Fixed /GETKEY nick@server not to crash if the server entry
1371 is not found. Affected file lib/silcclient/command.c.
1373 * Fixed the silc_server_check_cmode_rights to check the
1374 requested modes correctly. Affected file silcd/command.c.
1376 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1378 * Better checks for non-printable chars in nick added.
1379 Affected file silcd/command.c.
1381 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1383 * Call the silc_server_udpate_servers_by_server in the
1384 primary router that comes back online in the backup resuming
1385 protocol. Otherwise it routes packets wrong. Affected file
1386 silcd/server_util.[ch], silcd/server_backup.c.
1388 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1390 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1391 lib/silcutil/silcbuffmt.[ch].
1393 * Redefined the SILC packet header to include the padding
1394 length. Affected file lib/silccore/silcpacket.[ch].
1396 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1397 length for maximum padding up to 128 bytes). Affected
1398 file lib/silccore/silcpacket.h.
1400 * Removed all backwards support for old 0.5.x MAC thingies.
1401 The SILC packet header change makes it impossible to be
1402 backwards compatible.
1404 * Send the ENDING packet with timeout in the backup resuming
1405 protocol. This is to assure that all routers has connected
1406 to the primary router. Affected file silcd/server_backup.c.
1408 * Changed the RNG to take the first IV from random data. It
1409 used to take it from zero actually. Changed the RNG also
1410 to use /dev/urandom during session. /dev/random is used
1411 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1413 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1415 * Changed the SILC packet header to have the first two bytes
1416 (the packet length) encrypted. Affected files aroung the
1417 code tree, lib/silccore/silcpacket.[ch]. Removed the
1418 SilcPacketCheckDecrypt callback. It is not needed anymore
1419 since the silc_packet_receive_process will determine now
1420 whether the packet is normal or special.
1422 * Implemented the unidirectional MAC keys. Affected files
1423 lib/silcske/silcske.c, silcd/protocol.c and
1424 lib/silcclient/protocol.c.
1426 * Implemented the packet sequence number to the MAC computation.
1427 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1428 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1429 lib/silcclient/protocol.c.
1431 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1433 * Allow backup router to announce servers. All servers
1434 announced by backup router are added to the global list
1435 automatically. Update hte server's socket to our primary
1436 router also when backup router announces a server.
1437 Affected file silcd/packet_receive.c.
1439 * Do not update the client->router in the function
1440 silc_server_udpate_clients_by_server if the client is on
1441 global list. We might fail to find any specific server
1442 for locally connected clients and local cell clients. They
1443 should still use the `from' and not `to' as client->router.
1444 This fixes backup router resuming protocol. Affected file
1445 silcd/server_util.c.
1447 * Decrease channel statistics count only if the channel
1448 deletion worked. Affected files are silcd/server.c and
1449 silcd/server_util.c.
1451 * Added silc_server_update_servers_by_server to update origin
1452 of all server entries. Used during backup router protocol.
1453 Affected files silcd/server_util.[ch], silcd/server.c. and
1454 silcd/backup_router.c.
1456 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1457 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1458 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1459 lib/silccrypt/silchmac.c.
1461 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1463 * Assure that router cannot reroute the same channel message
1464 to the sender. Affected file silcd/packet_receive.c.
1466 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1468 * Made better checks that the channel message is not sent
1469 to the router it came from. Affected file is
1470 silcd/packet_send.c. Fixed memory leak too.
1472 * Announce informations for incoming router connection, but
1473 only after checking if it is replaced by backup router.
1474 Affected file silcd/packet_receive.c.
1476 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1478 * Fixed the backup resuming protocol to work in multiple
1479 router environment. Affected file silcd/server_backup.c.
1481 * Route packet only to one router in the function
1482 silc_server_packet_send_to_channel. Affected file is
1483 silcd/packet_send.c.
1485 * Fixed silc_server_send_notify_dest to set the broadcast
1486 flag. Fixed the silc_server_send_notify_topic to actually
1487 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1488 Affected file silcd/packet_send.c.
1490 * Changed the SFTP Filesystem interface. Changed the
1491 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1492 the filesystem operation function. The SilcSFTPFilesystem
1493 is now a context that is allocated by all filesystem allocation
1494 functions and it already includes the operations structure
1495 and filesystem specific context. It is given as argument
1496 now to the silc_sftp_server_start. This made the interface
1497 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1498 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1500 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1502 * Changed the backup router adding and getting interfaces
1503 in the server. The router that will be replaced by the
1504 specified backup router is now sent as argument. Affected
1505 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1508 * Added silc_net_addr2bin_ne to return the binary form of
1509 the IP address in network byte order. Affected files
1510 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1512 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1514 * Check for existing server ID in silc_server_new_server
1515 and in silc_server_connect_to_router_final and remove the
1516 old entry if it exists. Affected file silcd/packet_receive.c,
1519 * Send the channel message always to only one router, either
1520 in upstream or downstream. Affected file is
1521 silcd/packet_send.c.
1523 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1525 * Wrote the definition of the backup resuming protocol to the
1526 protocol specification.
1528 * Removed one redundant channel key generation from normal
1529 server during joining procedure. Removed one redundant
1530 channel key sending from server to router during joining
1531 procedure. Affected file silcd/command.c.
1533 * Made minor bugfixes to the backup router resuming protocol.
1534 Affected file silcd/server_backup.c, server.c.
1536 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1538 * Added --disable-asm configuration option. Affected files
1539 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1542 * Implemented the backup resuming protocol that is used to
1543 resume the primary router position in the cell after the
1544 primary router comes back online. Affected files
1545 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1546 and silcd/server_util.[ch].
1548 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1550 * Sleep two (2) seconds after sending QUIT command to server.
1551 Affected file lib/silcclient/command.c.
1553 * Assure that if outgoing data buffer is pending do not force
1554 send any data. Affected file silcd/packet_send.c.
1556 * Assure that if outgoing data buffer is pending do not force
1557 send any data. Affected file lib/silcclient/client.c.
1559 * Implemented the backup router support when the primary router
1560 goes down. The servers and routers can now use the backup
1561 router as new primary router without loosing connectivity.
1563 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1565 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1566 in the server to indicate disabled entry. All data read
1567 from the connection will be ignored and no data is sent
1568 for entry that is disabled. Affected files are
1569 silcd/idlist.h, silcd/server.c.
1571 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1573 * Created SFTP client and server test programs in the
1574 lib/silcsftp/tests directory.
1576 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1578 * Implemented memory filesystem (virtual filesystem) for
1579 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1582 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1584 * Implemented the SFTP (SSH File Transfer Protocol) to the
1585 lib/silcsftp. It includes SFTP client and SFTP server
1588 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1590 * Moved lib/silccore/silcprotocol.[ch] to the
1591 lib/silcutil library.
1593 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1594 take variable argument list pointer as argument. Affected
1595 file lib/silcutil/silcbuffmt.[ch].
1597 * Added silc_buffer_set function that is used to set data
1598 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1599 Affected file lib/silcutil/silcbuffer.h.
1601 * Changed various routines in the core library to use the new
1602 silc_buffer_set instead of allocating new buffer only for
1605 * Added 64-bit value formatting and unformatting support to the
1606 silc_buffer_[un]format routines. Affected file is
1607 lib/silcutil/silcbuffmt.[ch].
1609 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1610 to includes/bitmove.h.
1612 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1614 * Fixed channel user mode saving in client library. Affected
1615 file lib/silcclient/command[_reply].c.
1617 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1619 * Defined the file transfer to the SILC Protocol. Added
1620 new packet type SILC_PACKET_FTP and defined File Transfer
1621 Payload. The mandatory file transfer protocol is SFTP
1622 (SSH File Transfer Protocol). Affected file in addition
1623 of the internet draft is lib/silccore/silcpacket.h.
1625 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1626 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1627 is used as part of backup router protocol when the primary
1628 router of the cell is back online and wishes to resume
1629 the position as primary router.
1631 * Redefined the MAC generation keys in the protocol. The
1632 same key is not used anymore in both direction. Both
1633 direction will now use different keys for sending and
1634 receiving. This fixes a potential security flaw. This
1635 change causes incompatibilities in the protocol.
1637 * Redefined also the MAC computation from the packet.
1638 An packet sequence number is now added to the MAC
1639 computation. This prevents possible replay attacks against
1640 the protocol. This change too causes incompatibilities
1643 Added `sequence' field to the SilcPacketContext to hold
1644 the current sequence number for the packet.
1646 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1648 * Added `created' field to the SilcIDListData in the file
1649 silcd/idlist.h to indicate the time when the entry was
1652 * Added `created' field to the SilcChannelEntry too. Affected
1653 file silcd/idlist.h.
1655 * Added `creation_time' aguments to all the announcement functions
1656 in the server. If it is provided then only the entries that
1657 was created after the provided time frame are actually
1658 announced. Affected file silcd/server.[ch].
1660 * The protocol says that the Channel ID's IP address must be
1661 based on the router's IP address. Added check for this in
1662 the silc_server_new_channel when processing incoming New Channel
1663 Payload. Affected file silcd/packet_receive.c.
1665 * Print out the correct version with --version in SILC client.
1666 Affected file irssi/src/silc/core/silc-core.c.
1668 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1670 * Fixed WHOWAS command to check for completnes of the client
1671 entry always, not just when the command is coming from client.
1672 Affected file silcd/command.c.
1674 * Added new function silc_server_packet_queue_purge to purge the
1675 outgoing data queue to the network. After the function returns
1676 it is guaranteed that the outgoing packet queue is empty.
1677 Affected file silcd/packet_send.[ch].
1679 * Purge the outgoing packet queue in the rekey protocol's final
1680 callback to assure that all rekey packets go to the network
1681 before quitting the protocol. Affected file silcd/server.c.
1683 * Added silc_client_packet_queue_parse as similar function as
1684 in server to the client library. The affected file is
1685 lib/silcclient/client.c.
1687 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1689 * Splitted silcd/server.c and created silcd/server_util.[ch]
1690 for utility functions.
1692 * Added new socket flag SILC_SF_DISABLED to indicate that the
1693 connection is open but nothing can be sent to or received from
1694 the connection. Affected file lib/silcutil/silsockconn.[ch].
1695 The checking for disabled socket is checked in the low level
1696 silc_socket_write and silc_socket_read functions.
1698 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1700 * Allow only nicknames and channel names that fits into the
1701 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1703 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1705 * When processing JOIN command reply in server check that if
1706 the channel exists in our global list we'll move it the local
1707 list. Affected file silcd/command_reply.c.
1709 * Fixed the check whether client is joined on the channel already
1710 in JOIN command. Affected file lib/silcclient/command.c.
1712 * Fixed the JOIN command reply to check whether the channel
1713 already exists. Affected file lib/silcclient/command_reply.c.
1715 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1717 * Added silc_ske_status_string to map the SKE error numbers
1718 to readable strings. The affected files are
1719 lib/silcske/silcske[_status].[ch].
1721 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1723 * Do not show the private channels on the WHOIS channel list
1724 as it is not allowed by the protocol. The affected file is
1727 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1729 * Assure that the packet length digged from the actual packet
1730 is something sensible in the silc_packet_decrypt_rest_special
1731 in lib/silccrypt/silcpacket.c.
1733 * Free and NULL the allocated pointer in silc_hmac_alloc if
1734 the HMAC allocation fails. The affected file is
1735 lib/silccrypt/silchmac.c.
1737 * Print the selected security properties to the log files in
1738 the server. Affected file silcd/protocol.c.
1740 * Add SKE's reference counter even if calling the completion
1741 callback manually. Otherwise it goes negative, although it
1742 does not cause any problems. The affected file is
1743 lib/silcske/silcske.c.
1745 * Remove the client entry with short timeout after giving the
1746 KILL command. Affected file lib/silcclient/command.c.
1748 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1749 case all found clients are already disconnected (WHOWAS would
1750 found them) in the server. Affected file silcd/command.c.
1752 * Update the last_receive (time of last data received) to be
1753 updated only when received private or channel message so that
1754 the idle time showed in WHOIS makes more sense.
1756 * Added boolean field `valid' in to the SilcClientEntry in the
1757 client library to indicate whether the entry is valid or not.
1758 This fixes the nickname change bug on channel when changing
1759 the nickname to be same than the old (like nick to Nick) the
1760 nickname formatter doesn't set the new nick anymore to Nick@host.
1761 Affected file lib/silcclient/idlist.[ch].
1763 * Now actually fixed the nickname changing on disconnection.
1764 Added new function silc_change_nick to the Irssi SILC Client.
1765 Affected file irssi/src/silc/core/client_ops.c,
1766 irssi/src/silc/core/silc-nicklist.[ch].
1768 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1770 * Check that the public key exists in the GETKEY command before
1771 trying to encode it. Affected file silcd/command.c.
1773 * Print some notifications on received public keys with GETKEY
1774 command in the Irssi SILC Client. Affected files are
1775 irssi/src/fe-common/silc/module-formats.[ch],
1776 irssi/src/silc/core/client_ops.c.
1778 * Use IDENTIFY command to resolve the server information in the
1779 GETKEY command instead of INFO command. Affected file
1780 lib/silcclient/command.c.
1782 * All command reply functions in the client library now calls
1783 the pending command reply callbacks even if an error has
1784 occurred. The server has done this a long time and now it was
1785 time to move the client library to this as well. Now all
1786 errors can be delivered back to the pending command reply
1787 callbacks if necessary. Affected files are
1788 lib/silcclient/command[_reply].[ch].
1790 * Change the nickname on disconnection back to the username
1791 because in reconnect the server will enforce it to it anyway.
1792 Affected file irssi/src/silc/core/silc-servers.c.
1794 * Fixed a config file parsing bug in the Irssi SILC client.
1795 Affected file irssi/src/silc/core/clientconfig.c.
1797 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1799 * When printing the channel mode on JOIN, verify that the
1800 channel key and channel's HMAC are valid. Affected file
1801 irssi/src/silc/core/client_ops.c.
1803 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1805 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1806 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1807 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1809 * Removed channel key rekey task deleting from the function
1810 silc_server_save_channel_key. Affected file silcd/server.c.
1811 Added explicit timeout task context instead that is used to
1812 delete the task if we are registering a new task before the
1813 new task has elapsed.
1815 * When channel key rekey occurs the client library now saves
1816 the old channel key for a short period of time (10 seconds) and
1817 is able to use it in case some is still sending channel
1818 messages encrypted with the old key after the rekey. Affected
1819 file lib/silcclient/[idlist.h|client_channel.c].
1821 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1823 * Added check to the silc_server_new_id_real to not accept
1824 new ID if it is the sender's own ID. Affected file is
1825 silcd/packet_receive.c.
1827 * Assure that we do not announce ourself or the one we've
1828 sending our announcements when we're router and are announcing
1829 servers to our primary router. Affected file silcd/server.c.
1831 * Fixed silc_server_command_identify_check_client to assemble
1832 correct WHOIS packet. It send corrupted WHOIS packet and
1833 caused problem with router to router connections. Affected
1834 file silcd/command.c.
1836 Fixed also silc_server_command_whois_check the same way
1837 as for the IDENTIFY command.
1839 * Added new SilcIDListStatus to the server in the SilcIDListData
1840 structure. The status now includes the current status of
1841 the entry (like registered, resolved etc.). Affected file
1842 silcd/idlist.[ch]. Defined a bunch of different status types
1843 as well. This replaced the old boolean registered field as well.
1845 Added resolve_cmd_ident field to the SilcClientEntry structure
1846 too so that if the entry is for example being resolved so
1847 another command may attach to the same pending command reply
1848 without requiring to resolve the same entry again. This concept
1849 should optimize the WHOIS and the IDENTIFY resolving under
1850 heavy load by taking away unnecessary resolving for entries
1851 that are being resolved already.
1853 Added support for adding multiple pending commands for one
1854 command idenfier. Affected file silcd/command[_reply].[ch].
1856 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1857 before deleting the data. Otherwise the hash table will have
1858 freed data in comparison functions. Affected file is
1859 silcd/command_reply.c.
1861 * Fixed silc_idlist_replace_client_id to add the new entry to
1862 the cache with NULL nickname. Otherwise there will be invalid
1863 memory as the nickname after the nickname is freed. Affected
1864 file silcd/packet_receive.c.
1866 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1867 saved into wrong slots because the previous number of entries
1868 was not taken into account. Affected file silcd/idlist.c.
1869 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1871 * If we are router and we receive JOIN notify to a channel that
1872 does not have any users then notified client is marked as the
1873 channel founder, as it is it. The affected file is
1874 silcd/packet_receive.c
1876 * Added to the extended hash table API's table_del_*ext functions
1877 the destructor as argument too, so that the caller can decide
1878 which destructor to use or whether to use destructor at all.
1879 Affected file lib/silcutil/silchashtable.[ch].
1881 * Fixed ID Cache purging. It actually deleted the entries from
1882 the hash table after the data was freed. The hash table ended
1883 up comparing freed memory. The affected file is
1884 lib/silccore/silcidcache.c.
1886 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1888 * Fixed Irssi SILC client's KILL command's HELP syntax.
1890 * The USERS command now resolves the detailed user information
1891 if the userinfo field is missing. Affected file is
1892 lib/silcclient/command_reply.c.
1894 * Do not print error in silc_file_read if the read file does
1895 not exist. Just silently return NULL. Affected file is
1896 lib/silcutil/silcutil.c.
1898 * Fixed the silc_log_output to not wine about NULL filename
1899 and to not create some bogus " " filename. Affected file is
1900 lib/silcutil/silclog.c.
1902 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1904 * Fixed various printing bugs on the user interface in the
1905 Irssi SILC Client. Minor changes that were forgotten from
1908 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1910 * Fixed the configure.in.pre and the compilation and distribution
1911 environment to support the new autoconf 2.52. That version is
1912 now required to compile the CVS trunk.
1914 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1916 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1917 to generally parse user@fqdn format strings. Affected file
1918 lib/silcutil/silcutil.c.
1920 * Added nickname_format and nickname_force_format fields to the
1921 SilcClientParams structure. The first one defines the format
1922 for the nicknames that the library will enforce if the receives
1923 multiple same nicknames. The second one is boolean value and
1924 can be used to force the library to always enforce the format
1925 to the nicknames regardles whether there are multiple nicknames
1926 or not. This configurable formatting was employed to flexibly
1927 support accessing multiple nicknames from the user interface.
1928 The userinterface can now set the nicknames to what ever format
1929 they prefer. Affected file lib/silcclient/silcapi.h.
1931 Added function silc_client_nickname_format to the file
1932 lib/silcclient/idlist.c. It performs the nickname formatting.
1934 Added new field `hostname´ to the SilcClientEntry context.
1935 It holds the hostname of the client. Affected file is
1936 lib/silcclient/idlist.h.
1938 * Irssi SILC Client sets the nicknames in nick@hostn format.
1939 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1940 irssi/src/silc/core/silc-core.c.
1942 The WHOIS printing now also shows both the real nickname and
1943 the formatted nickname so that user knows how to access the
1944 user if there are multiple same nicknames cached. Affected
1945 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1946 printing formatting too to take the hostname now as a separate
1947 argument. The Affected file is
1948 irssi/src/fe-common/silc/modules-formats.[ch].
1950 * Changed the silc_client_get_clients_local to accept the formatted
1951 nickname as argument. It accepts the real nickname too but the
1952 formatted nickname can be used to find the true entry from
1953 multiple entries. Affected file lib/silcclient/silcapi.h and
1954 lib/silcclient/idlist.c.
1956 * Added nickname_format_parse field to the SilcClientParams.
1957 It is a callback function provided by the application to parse
1958 the nickname out of the formatted nickname string. The library
1959 calls it to get the nickname from the formatted string. Since
1960 the application generally knows better the format of the nickname
1961 string it parses it instead of the library, even though library
1962 encodes the formatted string. If the callback function is not
1963 provided then the library will use the string as is. The
1964 affected file is lib/silcclient/silcapi.h.
1966 * All the nickname strings passed to the client library in
1967 commands are now expected to be formatted nickname strings.
1968 If the command does not support the formatted nickname string
1969 it will assume that the sent string is the actual nickname.
1970 Affected file lib/silcclient/command.c.
1972 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1974 * Added public key authentication support to OPER and SILCOPER
1975 commands in the client library. Affected file is
1976 lib/silcclient/command.c.
1978 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1980 * Changed the get_auth_methdod client operation to be asynchronous.
1981 It can be async if the application resolves the authentication
1982 method from the server during the negotiation. Added new
1983 SilcGetAuthMeth completion callback that the application will
1984 call after resolving the authentication method.
1986 Added function silc_client_request_authentication_method that
1987 the application can use to resolve the authentication method
1988 from the server. Added also SilcConnectionAuthRequest callback
1989 that the library will call after the server has replied. The
1990 application can call this function if it does not know the
1991 current authentication method.
1993 Affected files are lib/silcclient/client.c and
1994 lib/silcclient/silcapi.h.
1996 * The Irssi SILC client now automatically resolves the authentication
1997 method incase any configuration information is not present (and
1998 currently there never is). The affected file is
1999 irssi/src/silc/core/client_ops.c.
2001 * Fixed public key authentication from the client library.
2002 Affected file lib/silcclient/protocol.c. Changed also the
2003 protocol specification about the public key authentication in
2004 the connection authentication protocol. The actual data to be
2005 signed is now computed with a hash function before signing.
2007 * Fixed the public key authentication from the server as well.
2008 Affected file silcd/protocol.c.
2010 * Removed the mlock()'s from the memory allocation routines.
2011 Affected file lib/silcutil/silcmemory.c. The ./configure does
2012 not check anymore for the mlock(). Affected file is
2015 * Fixed USERS command in server to allow the execution of the
2016 command for private and secret channels if the client sending
2017 the command is on the channel. Affected file silcd/command.c.
2019 * Fixed silc_client_get_clients_local to return the clients
2020 count correctly. It could return wrong value. Affected file
2021 lib/silcclient/idlist.c.
2023 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2025 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2026 types. The assembler optimizations seemed not to like 64-bit
2027 data types. The assmebler optimizations thus are now enabled
2028 also for BSD systems as opposed to only enable them for Linux.
2030 * Do not check for threads at all on BSD systems. Affected
2031 file configure.in.pre.
2033 * Removed -n and -h options from the Irssi SILC Client since
2034 they are not used in silc.
2036 * Fixed the prime generation to assure that the first digit
2037 of the generated random number is not zero since our conversion
2038 routines does not like number strings that starts with zero
2039 digit. If zero digit is seen the random number is regenerated.
2040 This caused some corrupted RSA keys when the zero first digit
2041 was met. Affected file lib/silcmath/silcprimegen.c.
2043 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2045 * Fixed WIN32 configuration in the ./configure script.
2046 Fixed to include xti.h on environments that has it.
2047 Patches by Carsten Ilchmann and andrew.
2049 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2051 * Changed the silc_id_create_client_id to be collision
2052 resistant. It is now assured that there cannot be created
2053 two same client ID's. I suspect that some weird bugs in
2054 the server were actually caused by duplicate Client IDs.
2055 Affected file silcd/serverid.[ch]. A router receiving
2056 new ID now also assures and informs the sending server
2057 if the ID caused collision.
2059 * Changed the silc_id_create_channel_id to also assure that
2060 there are no collisions.
2062 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2064 * Statement about ignoring the Mutual Authentication flag when
2065 performing rekey with PFS was a bit misleading. It is ignored
2066 if it was set in the initial negotiation, it cannot be even
2067 set in the rekey. Fixed in the ke-auth draft. Started the
2068 new versions of the protocol drafts in the doc/.
2070 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2072 * Fixed a bug in silc_client_command_identify_save when saving
2073 new channel information. The channel name was no duplicated
2074 and caused crash on exit. Affected file is
2075 lib/silcclient/command_reply.c.
2077 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2079 * Fixed the getkey command handling in the server. Send just
2080 empty OK reply to the sender if the key could not be fetched
2081 (but everything else was ok, like the key just was not available).
2082 Changed the public key parameter to optional in the protocol
2083 specs so that empty OK reply can be sent. Affected file
2086 Added a message to Irssi SILC client to tell to user if the
2087 server did not return a public key.
2089 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2091 * Fixed a channel key regeneration bug. It registered new
2092 timeout tasks exponentially until all system resources were
2093 used. Affected file silcd/server.c.
2095 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2097 * Added the SILC Document generator to the scripts/silcdoc.
2098 It can be used to generate the Toolkit Reference Manual out
2099 of the source tree. Internally it will also use the RoboDoc
2100 generator now imported in util/robodoc.
2102 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2104 * Added couple of return's in rekey protocol if error orccurred
2105 during the protocol. The execution must be terminated.
2106 Affected file silcd/protocol.c. Also, terminate the protocol
2107 always with timeout.
2109 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2111 * The client's Client ID was created initally from the wrong
2112 nickname (it could have been in format nick@host) in the
2113 silc_server_new_client. Affected file silcd/packet_receive.c
2115 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2117 * Added some SILC_LOG_ERROR's to various error conditions
2118 if client could not be added to ID cache. Affected files
2119 silcd/packet_receive.c and silcd/server.c.
2121 * When client's sock->user_data is freed, NULL also the
2122 client->router and client->connection pointers. Added check
2123 for these pointers being NULL to various places around the
2124 code. Affected file silcd/server.c.
2126 * Added client->data.registered == TRUE checks to various
2127 places around the code to assure that unregistered client's
2128 are not handled when it is not allowed. Affected file
2131 * Added `bool registered' fields to all
2132 silc_idlist_[server|client]_get_* routines to indicate whether
2133 the fetched client needs to be registered or not. Affected
2134 file silcd/idlist.[ch].
2136 * Add your own entry as registered to the ID cache in the
2137 server. Affected file server.c.
2139 * Fixed a bug in silc_server_new_server. The SilcServer was
2140 set as the new server's context instead of SilcServerEntry.
2141 This naturally caused some weird bugs.
2143 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2145 * Do not delete the channel rekey task when adding it
2146 for in silc_server_create_channel_key.
2148 * Changed the silc_server_create_channel_key to return
2149 TRUE or FALSE to indicate the success of the channel key
2152 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2154 * Fixed MSVC++ project files and added missing files to
2155 Makefiles under win32/.
2157 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2159 * Do not add TCP_NODELAY flag if the operating system
2160 does not have it defined. Affected files are
2161 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2163 * Fixed buffer overflow from Irssi SILC Client. Affected
2164 file irssi/src/fe-common/core/themes.c.
2166 * Fixed double free in client library in the file
2167 lib/silcclient/client.c when disconnecting from server.
2169 * Applied double free patch from cras to Irssi SILC client.
2170 Affected files irssi/src/core/[modules/expandos].c
2172 * Fixed the disconnection handling to Irssi SILC Client.
2173 The application must call silc_client_close_connection
2174 in ops->connect client operation in case of failure of
2175 the connection. Affected file is
2176 irssi/src/silc/core/client_ops.c.
2178 * Do not set sock->protocol to NULL in the function
2179 silc_client_close_connection after executing the protocol's
2180 final callback since the sock might not be valid anymore.
2181 Affected file lib/silcclient/client.c.
2183 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2185 * Do not enable SILC_THREADS if the linking with libpthread
2186 did not happen. Affected file configure.in.pre.
2188 * Added notion to protocol specification that server must
2189 verify the sent authentication payload with CMODE when
2190 setting the channel founder key. Implemented it to the
2191 server. Affected file silcd/command.c.
2193 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2195 * Added _EXTRA_DIST SILC distribution variable to the
2196 distributions file. It is used to conditionally add extra
2197 files or directories to the specific distribution. Affected
2198 files ./prepare, Makefile.am.pre and distributions.

2203 * Added README.WIN32 for instructions to compile the Toolkit
2206 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2208 * Fixed a double free in disconnection in the server. Affected
2209 file is silcd/server.c.
2211 * Fixed the lib/silcske/groups.c to work now also with GMP
2212 MP library. The string conversion did not work when using
2213 specific base and the base is indicated in the string as well.
2215 * Created win32/ directory which now includes MSVC++ specific
2216 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2217 It will appear only in the toolkit distribution
2219 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2221 * Changed the key material distribution function in case when
2222 the hash output is too short. The data is now concatenated
2223 a bit differently than it used to. Made the change to the
2224 SKE protocol specification.
2226 * Added better GMP detection to configure.in.pre. A patch
2229 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2231 * Fixed a minor bug in SKE that might cause some problem on
2232 some platforms. Affected file lib/silcske/silcske.c.
2234 * Added the cookie checking for initiator in the SKE. It checks
2235 that the responder returns the sent cookie unmodified. The
2236 affected file is lib/silcske/silcske.c. Added new SKE
2237 error type INVALID_COOKIE that can be sent during the
2238 negotiation. Fixed some memory leaks as well.
2240 * Added the "invalid cookie" error message to Irssi SILC client's
2243 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2245 * Added `task_max' field to the SilcClientParams to indicate
2246 the maximum tasks the scheduler can handle. If set to zero,
2247 default values are used. Affected file lib/silcclient/silcapi.h.
2249 * Fixed memory leaks in silc_client_close_connection. Affected
2250 file lib/silcclient/client.c.
2252 * Added silc_client_del_client_entry to client library to free
2253 all memory of given client entry. Affected file is
2254 lib/silcclient/idlist.[ch].
2256 * Added new functions silc_client_del_channel and
2257 silc_client_del_server to delete channel and server entries.
2258 Affected file lib/silcclient/[silcapi.h/idlist.c].
2260 * Removed silc_client_del_client_by_id from silcapi.h.
2262 * Fixed the INFO command to return the server's own info
2263 correctly when querying by Server ID. Affected file is
2266 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2268 * Removed the non-blocking settings in WIN32 code in the
2269 silc_sock_[read/write] and added SleepEx instead. Affected
2270 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2271 of input data is now checked with FIONREAD and ioctlsocket.
2273 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2275 * Call silc_schedule_task_del_by_context in the
2276 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2277 Affected file lib/silccore/silcprotocol.c.
2279 * Call silc_protocol_cancel for active protocols in the
2280 silc_server_close_connection if the funtion
2281 silc_server_free_sock_user_data has not been called.
2282 Affected file silcd/server.c.
2284 * Generic tasks cannot be deleted using the del_by_fd
2285 task deleting function since generic tasks does not match
2286 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2288 * Added a notion to SILCOPER help file that the SILCOPER works
2289 only on router server, not on normal server.
2291 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2293 * Added for WIN32 support for the new scheduler as well.
2294 Affected file lib/silcutil/win32/silcwin32schedule.c.
2296 * Fixed the SHA1 implementation to work on various platforms.
2298 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2300 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2301 API. It is part of the scheduler now. Everything else is
2302 as previously but some functions has changed their names.
2303 Checkout the lib/silcutil/silcschedule.h for the interface.
2304 Updated all applications to use the new interface. Affected
2305 files are lib/silcutil/silcschedule.[ch].
2307 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2309 * Found a bug in the SKE implementation. The HASH value,
2310 specified by the protocol, was not computed correctly. The
2311 public key of the responder was not added to the computation
2312 even though it is mandatory. Affected file lib/silcske/silcske.c.
2313 This unfortunately causes incompatibilities with older
2314 clients and servers.
2316 * Added WIN32 specific network init and uninit functions:
2317 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2318 the Winsock2. Affected file lib/silcutil/silcnet.h and
2319 lib/silcutil/win32/silcwin32net.c.
2321 * Set the socket always to nonblocking mode on WIN32 after
2322 reading data or writing data. Affected file is
2323 lib/silcutil/win32/silcwin32sockconn.c.
2325 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2327 * Fixed various compilation problems under WIN32. Affected
2328 files lib/silcutil/win32/silcwin32thread.c and
2329 lib/silcutil/win32/silcwin32schedule.c.
2331 * Removed all _internal.h #includes from public header
2332 files. Internal headers must never be included from
2335 Removed also the lib/silcske/payload_internal.h file.
2337 * All include files that may be needed (public and some others
2338 included by the public headers) by application developers are
2339 now copied to the ./includes directory. It does not copy any
2340 internal headers. Affected file Makefile.defines.pre and all
2341 Makefile.am's under lib/ and subdirs.
2343 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2345 * Do not change the ~/.silc directory's permissions automatically.
2346 Affected file irssi/src/silc/core/clientutil.c.
2348 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2350 * Do not cancel the protocol in silc_server_close_connection
2351 it might cause recursion. Now cancelled in the function
2352 silc_server_free_sock_user_data. Affected file silcd/server.c.
2354 * Fixed the silc_server_remove_clients_by_server to regenerate
2355 the channel keys correctly finally. Added also new function
2356 silc_server_remove_clients_channels to actually do it.
2357 Affected file silcd/server.c.
2359 * Fixed the silc_server_new_channel to not crash by giving
2360 wrong router to the new channel. Affected file is
2361 silcd/packet_receive.c.
2363 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2365 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2366 which is given as argument to the silc_client_alloc now.
2367 It can be used to configure the client and set various parameters
2368 that affect the function of the client.
2370 * The USERS command in server did not check whether the channel
2371 is private or secret. Affected file silcd/command.c.
2373 * Added new argument to the USERS command in protocol specification.
2374 The USERS command now can take the channel name as argument
2375 as well. Added support for this in client and server and
2376 updated the protocol specs.
2378 * Completed the GETKEY command in client. It can be now used
2379 to fetch also servers public key not only some clients.
2380 Affected files lib/silcclient/command[_reply].c.
2382 * Added silc_client_get_server to return server entry by the
2383 server name. Affected files lib/silcclient/silcapi.h and
2386 * Redefined the IDENTIFY command in protocol specification to be
2387 more generic. It now can be used to query information about
2388 any entity in the SILC Network, including clients, servers and
2389 channels. The query may be based either the entity's name
2390 or the ID. Added support for this in both client and server.
2392 Affected files silcd/command.c and lib/silcclient/command.c
2393 and command_reply.c.
2395 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2396 the _from_client and _from_server functions. Affected file
2399 * Added silc_client_get_channel_by_id_resolve to the file
2400 lib/silcclient/silcapi.h to resolve channel information by
2401 its ID. Added also silc_client_get_channel_by_id that
2402 does not resolve it from the server.
2404 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2406 * Added SilcServerEntry context into the client library
2407 to represent one server. The INFO command now allocates
2408 these to save the resolved server info. For now on the
2409 client library will also keep information about servers,
2410 connected and resolved with INFO.
2412 The INFO command now allocates the SilcServerEntry context
2413 and saves the server info there. The COMMAND_REPLY in
2414 the INFO now returns the parameters to application in
2415 same order as defined in the protocol specification.
2417 The entries are cached in the client->server_cache.
2419 * The INFO command is now issued after received the Client ID
2420 from the server. Affected file lib/silcclient/client.c.
2422 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2423 to the application as the mode changer might be server.
2424 It is guaranteed that NULL is not returned anymore to the
2425 application. Affected file lib/silcclient/client_notify.c.
2427 The ID Type is now also passed to the application so that
2428 it can check whether the returned entry is SilcClientEntry
2431 Added new function silc_client_get_server_by_id to return
2432 the server entry by ID. Affected files are the
2433 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2435 * Do not create the channel in the Irssi SILC Client when issuing
2436 the JOIN command but when received the sucessful JOIN command
2437 reply. Otherwise the channel might get created even though we
2438 could not join it. The Affected file is
2439 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2441 * Fixed a channel joining bug in router. The router must also
2442 check the channel modes, invite and ban lists etc. when serving
2443 the JOIN command sent by normal server. Affected file is
2444 silcd/command.c. The router now resolves the client's
2445 information from the server who sent the JOIN command if it
2446 does not know it, and processes the JOIN command only after
2449 * Changed the SilcCommandCb to take new argument; void *context2.
2450 Affected file lib/silccore/silccommand.h
2452 The second argument in the command callbacks in the server now
2453 includes the SilcServerCommandReplyContext if the command was
2454 called as pending command callback from the command reply.
2455 Otherwise it is NULL. When called as pending the status of the
2456 command reply will be checked and if it was erronous the
2457 error will be sent to the original sender of the command.
2458 This way the client always receives the error messages even
2459 though the server was actually the one who received the error
2460 when it resent the command to router, for example. Affected
2461 files silcd/command[_reply].[ch].
2463 * Fixed sending WHOWAS command's error message to client if
2464 the requested client could not be found. It was missing.
2467 * Changed the CMODE and CUMODE commands reply arguments in the
2468 protocol specification. The Channel ID is now sent in both
2469 of the commands to identify the channel. Implemented this
2470 new feature to the client and server. Affected files
2471 lib/silcclient/command_reply.c and silcd/command.c.
2473 * Made better checks for invite and ban lists in the JOIN
2474 command in server. Affected file silcd/command.c.
2476 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2478 * The server now performs the incoming host IP/DNS lookup
2479 using the silc_socket_host_lookup and thus does not block
2480 the server anymore. Affected file silcd/server.c.
2482 * Completed the multi-thread support for SILC Scheduler in
2483 the lib/silcutil/silcschedule.c.
2485 * Fixed the configure.in.pre to detect the pthread correctly
2488 * Fixed a deadlock in silc_task_queue_wakeup in the file
2489 lib/silcutil/silctask.c.
2491 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2493 * Added new function silc_schedule_wakeup that is used in
2494 multi-threaded environment to wakeup the main thread's
2495 schduler. It needs to be used when a thread adds a new task
2496 or removes a task from task queues. After waking up, the
2497 scheduler will detect the task queue changes. If threads
2498 support is not compiled in this function has no effect.
2499 Implemented the wakeup mechanism to both Unix and WIN32
2500 systems. Affected files are lib/silcutil/silcschedule.[ch],
2501 lib/silcutil/unix/silcunixschedule.c and the
2502 lib/silcutil/win32/silcwin32schedule.c.
2504 * Added new function silc_task_queue_wakeup to wakeup the
2505 scheduler by the specified task queue. Affected file
2506 lib/silcutil/silctask.[ch].
2508 * The silc_socket_host_lookup_start now wakes up the scheduler
2509 after adding the timeout task. Affected file is
2510 lib/silcutil/silcsockconn.c.
2512 * The silc_socket_host_lookup is synchronous now if the threads
2513 support is not compiled in. However, the callback is still
2514 called asyncronously through the scheduler, anyway. Affected
2515 file lib/silcutil/silcsockconn.c.
2517 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2519 * Added new function silc_socket_host_lookup to perform
2520 asynchronous IP and FQDN lookups for the socket connection.
2521 Affected files lib/silcutil/silcsockconn.[ch].
2523 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2525 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2526 that may or may not compile the mutex support in.
2528 Changed the silc_mutex_alloc interface. It allocates the
2529 mutex now to the sent pointer and returns TRUE or FALSE.
2531 Affected file lib/silcutil/silcmutex.h.
2533 * Wrote the SILC Task Queue interface to support multi-threads.
2534 Affected file lib/silcutil/silctask.[ch].
2536 * Wrote the SILC Scheduler to support multi-threads. Affected
2537 file lib/silcutil/silcschedule.c.
2539 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2541 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2542 in lib/silcutil/win32/.
2544 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2546 * Defined SILC Mutex API and SILC Thread API and implemented
2547 them for Unix. Affected files are
2548 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2549 lib/silcutil/unix/silcunixmutex.c and
2550 lib/silcutil/unix/silcunixthread.c.
2552 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2554 * Fixed the silc_server_remove_clients_by_server's channel
2555 key re-generation. The hash table handling was incorrect
2556 and would not work with many channels. Affected file is
2559 * Fixed some memory leaks around the server code.
2561 * Rewrote the silc_server_get_users_on_channel to support IPv6
2562 based Client ID's. Affected file silcd/server.c.
2564 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2565 specification. However, a separate document must be written
2566 to define the detailed signing procedure and the payload
2567 associated with the flag. Defined the flag to the
2568 lib/silccore/silcchannel.h as well.
2570 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2572 * Changed the dynamic tables to static size tables in the
2573 lib/silccrypt/silchmac.c.
2575 * Removed GCC dependencies from the code. A patch by cras.
2577 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2579 * Do not show the error "Error receiving packet bla bla"
2580 in server if it really was not an error (-2 means that reading
2581 is pending). Affected file silcd/server.c.
2583 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2585 * Fixed a possible crash in silc_server_remove_clients_by_server
2586 in silcd/server.c. Fixed there also some memory leaks.
2588 * Fixed the silc_idlist_replace_client_id. It could replace
2589 wrong key in the hash table. Affected file silcd/idlist.c.
2591 * Do not check whether there are global users on the channel
2592 if the channel->global_users is FALSE. Affected functions
2593 silc_server_remove_from_one_channel and
2594 silc_server_remove_from_channels in silcd/server.c. Also,
2595 do not check if the removed client is local as we can be
2596 sure that global client was not removed from the channel
2597 and checking for global users is not needed.
2599 * The silc_server_remove_clients_by_server now re-generates
2600 the channel keys correctly for those channels that had
2601 clients removed from them. Affected file silcd/server.c.
2603 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2605 * Found the reason of random crashes in the server. We weren't
2606 ignoring the SIGPIPE signal (which can be sent in write())
2607 and it crashed the server. Affected file silcd/silcd.c.
2609 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Assure that sock->user_data is not NULL in the function
2612 silc_server_packet_send in silcd/packet_send.c.
2614 * Disconnect the remote connection if it could not be added
2615 to any ID lists in the server. The affected file is
2618 * Check in silc_server_packet_send[_real/dest] that the
2619 socket is not disconnecting and ignore the data if it is.
2620 Affected file silcd/packet_send.c.
2622 * Define inline to __inline on native WIN32 compilation.
2623 Affected file includes/silcwin32.h.
2625 * Added some explicit type casts for inline code since MSVC
2626 require them. Affected files lib/silcutil/silcbuffer.h,
2627 lib/trq/silcdlist.h and lib/trq/silclist.h.
2629 * Print warning in log files from now on if the packet
2630 decryption fails. Affected file silcd/server.c.
2632 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2634 * Changed the `say' client operation's interface to accept
2635 new `type' argument to indicate the type of the message sent
2636 by the library. The application may filter the library's
2637 messages according the type. The affected file is the
2638 lib/silcclient/silcapi.h.
2640 * Added two new functions to lib/silcclient/silcapi.h:
2641 silc_client_del_client and silc_client_del_client_by_id.
2642 Affected file lib/silcclient/idlist.c.
2644 * Moved the clientincludes.h from includes/ to silc/ and
2645 serverincludes.h from includes/ to silcd/.
2647 * The modes for the CMODE and CUMODE are now passed as
2648 uint32 for application with COMMAND_REPLY. The affected
2649 file is lib/silcclient/command_reply.c.
2651 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2653 * /WHOIS without arguments shows client's own information.
2654 Affected file lib/silcclient/command.c.
2656 * Changed PING to not accept any arguments. The specs
2657 says that client can ping only the connected server so
2658 requiring an argument is not needed. Affected file is
2659 lib/silcclient/command.c.
2661 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2663 * Fixed a fatal bug in private message sending and reception
2664 encryption and decryption when using private message keys.
2665 The implementation was incorrect and did not follow the
2666 specification. It causd that some of the message were
2667 lost since it did not use the sending and receiving keys
2668 as the protocol suggests. This has been fixed and will cause
2669 incompatibilities with older clients when sending private
2670 message encrypted with private message keys. Affected files
2671 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2672 and various other in Irssi SILC Client.
2674 Added `responder' boolean argument to the functions
2675 silc_client_add_private_message_key[_ske] to indicate when
2676 the key is added as responder or initiator of the key
2679 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2681 * Removed the silc_ske_check_version function and created
2682 a SilcSKECheckVersion callback. Added also a function
2683 silc_ske_set_callbacks that is now used to set all SKE
2684 callbacks. The callback functions are not given to
2685 the SKE functions anymore, but this function is used to
2688 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2690 * Added `silc_version' argument to the silc_client_alloc
2691 to define the version of the application for the library.
2692 The library will use the version string to compare it
2693 against the remote host's (usually a server) version
2694 string. Affected file lib/silcclient/silcapi.h
2696 * Added the KE protocol context to Key Agreement context
2697 in client library so that we can abort the SKE if it
2698 is in process when we get timeout. Affected file is
2699 lib/silcclient/client_keyagr.c.
2701 * Do not resolve the client ID forever if it returns in the
2702 first time that such client does not exist. This was done
2703 for example with private message. Affected file is
2704 lib/silcclient/client_prvmsg.c.
2706 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2708 * Do not add regex.h for WIN32. The affected file
2709 includes/silcincludes.h.
2711 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2712 not work yet 100%. It generates the DLL's automatically
2713 when compiling with --with-win32 under cygwin.
2715 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2717 * lib/contrib/regex.c is not compiled on WIN32.
2719 * Added silc_net_get_socket_opt function to the
2720 lib/silcutil/silcnet.h.
2722 * Added includes/silcwin32.h for WIN32 specific includes
2725 * Do not use ptime structure or any of the posix process
2726 functions on WIN32 in lib/silccrypt/silrng.c.
2728 * Added silc_gettimeofday to provide generic function
2729 for struct timeval on all platforms. Added the function
2730 to lib/silcutil/silcutil.h.
2732 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2734 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2735 library as they clearly belong there. As a plus side we
2736 can make the actual socket connection routines platform
2739 Added also new generic function silc_socket_read and
2740 silc_socket_write (that used to be silc_packet_[read/write].
2741 The implementation of these are platform specific.
2743 * Added WIN32 specific routines of silc_socket_[read/write]
2744 to lib/silcutil/win32/silcwin32sockconn.c.
2746 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2748 * Added preliminary support for native WIN32 compilation under
2749 cygwin (using the -mno-cygwin option for GCC) to the
2750 ./configure.in.pre. The --with-win32 now prepares the
2751 compilation for native WIN32.
2753 * Rewrote the SILC Scheduler interface in the file
2754 lib/silcutil/silcschedule.h. The scheduler is now context
2755 based and does not have anymore any global static scheduler.
2756 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2757 and created lib/silcutil/win32 directory for WIN32 based
2760 * Added Unix specific network routines to the
2761 lib/silcutil/unix/silcunixnet.c and the old
2762 lib/silcutil/silcnet.c includes now only generic routines.
2764 Added WIN32 specific network routines to the
2765 lib/silcutil/win32/silcwin32net.c.
2767 * Added Unix specific utility functions from the
2768 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2770 * Added WIN32 SILC Scheduler to the file
2771 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2774 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2776 * Do not handle JOIN notify in the server if the target client
2777 is not registered (idata->registered == FALSE). The affected
2778 file is silcd/packet_receive.c.
2780 * Update the nickrec->founder in event_cumode in the Irssi SILC
2781 client. Affected file irssi/src/silc/core/silc-channels.c.
2783 * Fixed the CUMODE_CHANGE notify handling in the server when
2784 server and router are announcing their clients on channels.
2785 Now the mode changes are saved and notified correctly. The
2786 affected file is /silcd/packet_receive.c.
2788 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2789 They really did not replace the cache entry in the ID Cache.
2790 Now they do that. Affected file silcd/idlist.c.
2792 * Fixed the KICK notify handling in the Irssi SILC client to
2793 update the channel records so that the kicked client does not
2794 appear to be on the channel. The affected file is
2795 irssi/src/silc/core/silc-channels.c.
2797 * Always update the conn->current_channel when executing command
2798 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2800 * Fixed the KILL notify handling in Irssi SILC client to remove
2801 the killed client on all channels.
2803 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2805 * Fixed the silc_parse_command_line to remove extra spaces
2806 from the start and end of the arguments. Affected file is
2807 lib/silcutil/silcutil.c.
2809 * Cancel and free any active protocol in the function
2810 silc_server_close_connection. Affected file silcd/server.c.
2812 * Cancel and free any active protocol in the function
2813 silc_client_close_connction. Affected file is
2814 lib/silcclient/client.c.
2816 * Do not execute the KILL command for clients that are in
2817 history (ie. they are not in the network). Affected file is
2820 * Fixed KILL notify handling, client does not crash anymore.
2821 Affected file irssi/src/silc/core/silc-channels.c.
2823 * Reduced the default packet buffer size from 2048 to 1024 in
2824 lib/silccore/silcpacket.c.
2826 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2827 counter to the SKE context that is incresed when the SKE library
2828 performs async operation outside the library. If the outside
2829 process frees the SKE context and FREED status will be set
2830 and the library will detect after the sync operation that the
2831 libary is freed. The affected files are
2832 lib/silcske/silcske[_status].[ch].
2834 * Resolve the client entry information in the function
2835 silc_client_channel_message to assure that NULL pointer is not
2836 passed as client entry to the application. */
2838 * Fixed the task timeout calculation to assure that there is
2839 never negative timeouts. The affected file is
2840 lib/silcutil/silcschedule.c.
2842 * Fixed the channel user mode notification sending in server.
2843 It was sent point-to-point to the router (or to server by router)
2844 but it needs to be destined to a channel. The routines now
2845 supports sending the channel user mode notifys to the channels
2846 when announcing clients and channels. Affected files are
2847 silcd/server.c and silcd/packet_receive.c.
2849 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2850 It did not actually replace the old channel entry in the cache.
2851 Affected file lib/silcclient/client_notify.c.
2853 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2855 * Fixed a possible crash in silc_packet_send_prepare. It now
2856 assures always that there is enough space in the buffer and
2857 at the tail area of the buffer (for MAC).
2859 Fixed the inbound buffer reallocation in silc_packet_read.
2860 It was old code and did not handle the reallocation correctly.
2863 The affected file is lib/silccore/silcpacket.c.
2865 * Fixed buffer overflow in silc_parse_nickname in the file
2866 lib/silcutil/silcutil.c.
2868 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2870 * make install generates new server keys only if there is not
2873 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2875 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2876 Added check that if the NOREPLY is set then we will not send
2877 the away message. This avoids infinite loop of away messages
2878 if both clients are away. The affected file is
2879 lib/silcclient/client_prvmsg.c.
2881 * Fixed client crash if /NICK was given without arguments.
2882 Affected file lib/silcclient/command.c.
2884 * Server does not send the invite list in INVITE command back
2885 to the client if the list was not altered. Added this notion
2886 to the protocol spec as well. Affected file silcd/command.c.
2888 Fixed possible crash in INVITE command by checking the
2889 value of silc_server_get_client_route command.
2891 * Fixed the INVITE notify type handling. The arguments are now
2892 taken in correct order and client does not crash. The affected
2893 file is irssi/src/silc/core/silc-channels.c.
2895 Removed the "Inviting xxx to channel" message from the
2896 client library away and let the application handle it.
2897 Affected file lib/silcclient/command.c. Added that message
2898 to Irssi SILC client's message formats.
2900 * Fixed CMODE command crash in client. It now checks the
2901 amount of arguments correctly and does not crash. The affected
2902 file is lib/silcclient/command.c.
2904 * Do not create new channel automatically in silc_channels_join
2905 but check whether the channel by that name already exists.
2906 Affected file irssi/silc/core/silc-channels.c.
2908 * Do not send the SERVER_SIGNOFF to router if the disconnected
2909 entity was the router. Affected file silcd/server.c.
2911 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2912 SILC client as it was missing from there.
2914 Added the handling of the KICK notify to the Irssi SILC client
2915 as it was missing. Added "you have been kicked" message to
2916 Irssi SILC client's message modules formats.
2918 Added the handing of the KILL notify to the Irssi SILC client
2919 as it was missing. Added the kill message module formats
2922 The affected file is irssi/src/silc/core/silc-channels.c.
2924 * The router did not save the channel mode the server announced.
2925 Affected file silcd/packet_receive.c.
2927 * Fixed a possible crash in INFO command in server. If the
2928 server did not provide the server info it crashed. Affected
2929 file silcd/command.c.
2931 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2933 * Fixed the GETKEY command in the server to check also the
2934 global list. Otherwise the GETKEY would not work correctly
2935 in normal SILC server. Affected file silcd/command.c.
2937 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2939 * Fixed GETKEY crash, it crashed if the command did not succseed.
2941 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2943 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2944 is now real and not just an macro interface to GMP.
2946 Removed the entire GMP from the source tree and imported new
2947 NSS MPI library instead. Reason for removing GMP is that it is
2948 extremely large and compiles extremely slow. The NSS MPI
2949 is only a few files and compiles in less than 10 seconds.
2950 The speed is also about the same as GMP. The MPI is imported
2951 to lib/silcmath/mpi.
2953 If the system has GMP installed we will still use the GMP.
2954 If it is not then the NSS MPI will be compiled.
2956 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2958 * Merged a long nickname (127 characters long) crash bugfix from
2959 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2961 * Merged a freed memory reference bugfix from Irssi CVS tree.
2962 Affected file irssi/src/core/commands.c.
2964 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2966 * Added the server's public key sving and verification to the
2967 server when performing the SKE. This was missing and the
2968 remote server's (or router's) public key was accepted without
2969 checking whether we have it previously or trust it at all.
2970 Affected file silcd/protocol.c.
2972 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2974 * Check in the silc_server_timeout_remote if protocol is active
2975 and make sure that the protocol's final callback is called so
2976 that all memory if freed. Affected file silcd/server.c.
2978 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2980 * silc_server_whois_send_reply crashed the server if the nickname
2981 was 127 characters long. Affected file silcd/command.c.
2983 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2985 * Added sanity check to the silc_server_new_client. If the hostname
2986 is provided inside username then check that the provided hostname
2987 really is the same as the resolved one. If the hostname was not
2988 resolved then check it from the public key. Affected file is
2989 silcd/packet_receive.c.
2991 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2992 if the server disconnected us and the connection is not valid
2993 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2995 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2996 the library to the lib/silcutil/silcutil.[ch].
2998 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3000 * Close log file after open. Affected file
3001 lib/silcutil/silclog.c.
3003 * Check whether sock == NULL in silc_client_send_packet and return
3004 if it is. Affected file lib/silcclient/silcclient.c.
3006 * Check rec->entry == NULL in the Irssi SILC Client before
3007 sending the channel message. Affecte file is
3008 irssi/src/silc/core/silc-servers.c.
3010 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3012 * Merged a splitted window bugfix from Irssi CVS tree. The
3013 affected file is irssi/src/fe-text/textbuffer-view.c.
3015 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3016 It did not print nickname.
3018 * Improved the distributions system a bit.
3020 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3022 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3023 irssi/src/fe-text/gui-window.c.
3025 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3026 to in-active server. The affected file is
3027 irssi/src/silc/core/client_ops.c.
3029 * Resolve the client in USERS command reply if the entry does
3030 not have username resolved. The affected file is
3031 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3032 command to WHOIS command to really resolve stuff. The USERS
3033 is not used any more in any critical section so WHOIS can
3034 be used even though it might be slower than IDENTIFY.
3036 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3039 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3041 * Changed the protocol API a bit more consistent in the
3042 lib/silccore/silcprotocol.[ch].
3044 * Changed the following headers to ROBODoc format:
3046 lib/silccore/silcpayload.h
3047 lib/silccore/silcprotocol.h
3048 lib/silccore/silcsockconn.h
3050 All core library headers are now formatted.
3052 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3054 * Fixed a bug in Irssi SILC client; do not show that you are
3055 server/router operator if you really are not. Affected file is
3056 irssi/src/silc/core/client_ops.c.
3058 * Renamed silc_command_free_payload to silc_command_payload_free.
3059 Affected file lib/silccore/silccommand.h
3061 * Added silcmath.h to include the prototoypes of various routines
3062 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3065 * Changed the following headers to ROBODoc format:
3067 lib/silccore/silcchannel.h
3068 lib/silccore/silccommand.h
3069 lib/silccore/silcid.h
3070 lib/silccore/silcidcache.h
3071 lib/silccore/silcmode.h
3072 lib/silccore/silcnotify.h
3073 lib/silccore/silcpacket.h
3074 lib/silcmath/silcmath.h
3076 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3078 * Added checking to the server code not to start the server if
3079 ciphers and stuff are not configured properly. Affected files
3080 silcd/serverconfig.[h] and silcd/server.c.
3082 * Changed the layout of the header files of the public interfaces
3083 in the SILC libraries. The new layout supports ROBODoc
3084 documentation tool (and some others) so that it is easy to create
3085 a library reference manual. All the other headers and source
3086 code must still follow the CodingStyle document. Also source
3087 code must not include these ROBODoc stuffs, only the headers.
3088 Furthermore, all public interface headers must now be named
3089 by using `silc' prefix, example: silcapi.h, silccipher.h.
3090 Some files were renamed due to this. All the other headers
3091 must not be used as public interfaces. I will update the
3092 CodingStyle document later. Changed following headers, so far:
3094 lib/silcclient/silcapi.h
3095 lib/silccore/silcauth.h
3096 lib/silccore/silcprivate.h
3097 lib/silccrypt/silcdh.h
3099 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3103 * Removed silc_client_packet_send_flush from the client library
3104 as it is not needed. Affected file lib/silcclient/client.[ch].
3106 * Added printing of message of unresolved authentication method
3107 to the Irssi SILC client. Added it to the module formats.
3108 Removed the same message from the client library.
3110 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3112 * Added new distribution feature, DISTLABEL. Every distribution
3113 can define own preprocessor label that can be used in the
3114 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3115 file distributions, acconfig.h.pre and prepare.
3117 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3119 * Added Makefile.defines_int to include the actual definitions
3120 for Makefile.defines.in. Tested the new distribution system,
3121 created distributions and tested installation.
3123 * Added AWAY message printing to the Irssi SILC client. Added
3124 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3126 * Added SCONNECT command to call the SILC's CONNECT command.
3127 Cannot use CONNECT directly since Irssi uses that internally.
3128 Affected file irssi/src/silc/core/silc-servers.c.
3130 Added ACTION local command. It is same as ME command but takes
3131 the channel as mandatory argument.
3133 Rewrote some of the Irssi's help files to suite for SILC
3136 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3138 * Added Makefile.defines[.in] that should for now on be included
3139 in all Makefile.am file in the source tree. That file includes
3140 all common compilation definitions for SILC source tree.
3142 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3144 * Minor changes to the ./prepare script to change the package
3145 name according the distribution name to the configure.in.
3147 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3149 * Created new distribution system. Added file `distributions'
3150 that defines all the distributions that can be created out of
3151 the SILC source tree. The ./prepare script now reads that
3152 file to determine how to prepare the distributions. The
3153 first argument to the ./prepare is the name of the distribution
3154 and second is the version of the distribution. If given
3155 without arguments it creates the default (toolkit) distribution
3156 with the default version (defined in ./prepare).
3158 All Makefile.am files that are subject to the distributions
3159 are now named as Makefile.am.pre. These are ./Makefile.am
3160 and lib/Makefile.am. Others may be changed later.
3162 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3164 * Added invite list, ban list, some key management and connection
3165 error message printing to module formats in the Irssi SILC client.
3167 * Added new silc_client_set_away_message to set the away message
3168 that is back to the person who sent private message. The
3169 affected file lib/silcclient/silcapi.h and the
3170 lib/silcclient/client_prvmsg.c.
3172 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3174 * Fixed the private message sending in the Irssi SILC client,
3175 added local command KEY to the Irssi SILC client.
3177 Added key management and key agreement message formats to the
3178 irssi/src/fe-common/silc/module-formats.[ch].
3180 Added USERS (alias WHO) printing, server/router operator
3181 indication and LIST command printing to the module formats.
3183 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3185 * Fixed channel joining notify handling, cumode notify handling
3186 from Irssi SILC client.
3188 * Added SILC specific module-formats to the Irssi SILC client so
3189 that SILC specific message hilighting, colors etc is possible.
3190 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3192 Added channel mode, channel user mode, actions, notices,
3193 whois and whowas printing to the the module-formats.c.
3195 * Fixed a bug in channel deletion in the server. The channel
3196 is not left to the cache even if the channel founder auth mode
3197 is set when there are no users anymore on the channel. Affected
3198 file silcd/server.c.
3200 * The silc_net_localhost now resolves the entire hostname including
3201 the domain name. Affected file lib/silcutil/silcnet.c.
3203 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3205 * Changed the ask_passphrase client operation to be ascynchronous.
3206 It has now a completion callback and a context that the
3207 application must call after it has got the passphrase from
3208 the user. Affected files lib/silcclient/silcapi.h,
3209 lib/silcclient/protocol.c, lib/silcclient/command.c and
3212 Added SilcAskPassphrase callback that the application calls
3213 to deliver the passphrase to the library.
3215 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3216 The public key verification and especially a certificate
3217 verification is asynchronous procedure.
3219 Added new SILC_SKE_STATUS_PENDING status to indicate the
3220 request is pending and a callback will be called to finalize
3223 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3224 indicate that remote end did not send its public key (or
3225 certificate), even though we require it. Added check for this
3226 condition in the SKE. This was a security bug, now fixed.
3228 Defined new SilcSKEVerifyCbCompletion callback that is called
3229 when the verification process is completed.
3231 The affected files lib/silcske/silcske_status.h and
3232 lib/silcske/silcske.[ch].
3234 * Changed the verify_public_key client operation to be async
3235 as well. Defined SilcVerifyPublicKey callback that is used to
3236 indicate the success of the public key verification process.
3238 Changed the server and client to use the new async client
3241 * Changed the Irssi SILC client's internal scheduler to be called
3242 twice as many times as it used to be. As a result the client
3243 should be a bit faster now. Affected file is
3244 irssi/src/silc/core/silc-core.c.
3246 * Added support to Irssi SILC client of asynchronous public key
3247 verification and passphrase inquiry. Affected file is
3248 irssi/src/silc/core/silc-core.c.
3250 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3252 * Do not say "You have left channel %s" in client library.
3253 Moved it to the application. Affected files are
3254 lib/silcclient/command.c and silc/client_ops.c.
3256 * Fixed silc_client_get_clients. Command context was not
3257 duplicated and was freed memory in the callback. Affected
3258 file lib/silcclient/idlist.c.
3260 * Do not say "you are now talking..." on JOIN command in the
3261 client library. The appliation must handle it.
3263 * Do not say ".. changed topic to" in command reply in the
3264 client libary. The application must handle it.
3266 * Fixed TOPIC command sending in the client library.
3268 * Fixed a memory leak in silc_client_command_free in the file
3269 lib/silcclient/command.c.
3271 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3273 * Imported a modified version of Irssi client to the source tree.
3274 The Irssi will be used to create a new client called
3275 Irssi SILC. Imported to irssi/.
3277 Added silc_core_init_finish function to the Irssi. Affected
3278 file irssi/configure.in.
3280 A lot changes in the Makefile.ams around the irssi tree.
3282 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3284 * Do not rehash if the new size is same as the old size of the
3285 hash table, in the silc_hash_table_rehash*. The affected file
3286 lib/silcutil/silchashtable.c.
3288 * Replaced hash_table_del_by_context calls from the server
3289 (when channel->user_list and client->channels) to the
3290 hash_table_del as it is sufficient and faster.
3292 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3294 * Added silc_hash_table_list, silc_hash_table_get and the
3295 SilcHashTableList structure to provide an alternative way to
3296 traverse the hash table. The affected files are
3297 lib/silcutil/silchashtable.[ch].
3299 * Changed the server's idlist routines to use the hash table
3300 routines to optimize the code.
3302 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3304 * Replaced the client entry's `channel' list and channel entry's
3305 `user_list' list to hash tables for optimized lookup. Changed
3306 the code to use the hash table interface around the code.
3307 Affected file lib/silcd/idlist.[ch].
3309 * Added `auto_rehash' boolean argument to the function
3310 silc_hash_table_alloc to indicate whether the hash table should
3311 auto-rehash when it thinks is appropriate time. It will
3312 increase the hash table size if the there is twice as much
3313 entries in the table than the size of the table, and will
3314 decrease the size if there are twice as less entries than
3315 the size of the table.
3317 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3321 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3323 * silc_idcache_purge_by_context deletes the entry now by context
3324 as it is supposed to do. Affected file lib/silccore/idcache.c.
3326 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3327 client is not anymore valid (WHOWAS givens the info) and not
3328 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3330 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3332 * Removed the `data' and `data_len' arguments from the ID Cache
3333 interfaces and added `name' argument. ID Cache does not handle
3334 anymore the binary data only a names associated with given ID.
3336 * When hashing a Client ID with silc_hash_id the entire ID is
3337 not hashed anymore, instead only the hash of the Client ID is
3338 hashed. This way we can access the Client ID from the cache
3339 with Client ID but with the hash of the ID (which is a hash of
3340 the nickname) as well without any difference in performance.
3342 Added also silc_idcache_find_by_id_one_ext to do one on one
3343 searching when we have the actual ID. Added also function
3344 silc_hash_client_id_compare. The affected files are
3345 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3347 * When hashing the name associated with a ID it is always done
3348 in lowercase. This way we can access the cache without worrying
3349 about case-sensitivity, even though, for example nicknames are
3352 * Fixed a bug in server with channel message sending. It put
3353 wrong ID type as destination ID. The affected file
3354 silcd/packet_send.c.
3356 * silc_idcache_del_by_context now deletes from all hash tables
3357 by context. Affected file lib/silccore/idcache.c.
3359 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3361 * Changed the client library to use the new ID Cache interface.
3362 Changes around the source tree.
3364 * Added silc_hash_table_rehash_ext to rehash with specific
3365 hash function. Affected file lib/silcutil/silchashtable.[ch].
3367 * Added silc_hash_string_compare to compare two strings in the
3368 hash table. Affected file lib/silcutil/silcutil.[ch].
3370 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3372 * Added new function silc_idcache_del_by_context into the
3373 lib/silccore/idcache.[ch].
3375 * Changed the server's ID list routines to use the new ID Cache
3376 interface. Changes around the source tree.
3378 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Added silc_hash_table_del[_by_context]_ext functions in to the
3381 lib/silcutil/silchashtable.[ch].
3383 Removed silc_hash_table_find_all* routines and added new
3384 silc_hash_table_find_foreach to replace them.
3386 Added silc_hash_table_replace_ext function as extended
3387 replacing function. Separated the simple hash table interface
3388 from the extended hash table interface in the file
3389 lib/silcutil/silchashtable.h.
3391 * Fixed minor bugs and changed it to use some of the new
3392 hash table functions in lib/silccore/idcache.c
3394 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3396 * Added new function silc_hash_table_find_all to return all keys
3397 in the hash table by the specified key. As the hash table is
3398 collision resistant it also makes it possible to have several
3399 duplicate keys in the hash table. This function may be used to
3400 find all of the keys from the hash.
3402 Added user_context arguments to the SilcHashFunction,
3403 SilcHashCompare and SilcHashDestructor to deliver user specified
3406 Added new fuctions silc_hash_table_find[_all]_ext to do
3407 extended lookup with specified hash and compare functions and
3408 specified user contexts.
3410 Added new function silc_hash_table_add_ext to add the key
3411 with specified hash function and user context.
3413 Added new function silc_hash_table_foreach to traverse all
3414 entrys in the hash table. Added SilcHashForeach callback
3417 Added new function silc_hash_table_del_by_context to delete
3418 the entry only if the context associated with the key matches.
3420 Affected files are lib/silcutil/silchashtable.[ch].
3422 * Removed silc_hash_[server/client/channel]_id and added just
3423 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3424 silc_hash_id_compare to compare two ID's using as the hash table
3425 comparison function. Added also silc_hash_data to hash
3426 binary data and silc_hash_data_compare to compare it.
3428 * Removed silc_idlist_find_client_by_hash as it is not needed
3429 anymore. Affected file silcd/idlist.[ch].
3431 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3432 to use internally the SilcHashTable. The new ID Cache is a lot
3433 faster than the old one. Some of the ID Cache interface was also
3434 rewritten and obsolete and stupid functions were removed.
3436 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3438 * Added entry_count field to the SilcHashTable to keep the number
3439 of the entries in the table. Implemented the function
3440 silc_hash_table_rehash. Added new function
3441 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3443 Fixed a minor bug in silc_hash_table_free.
3445 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3446 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3447 into the lib/silcutil/silcutil.[ch].
3449 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3451 * Implemented a collision resistant hash table into the
3452 lib/silcutil/silchashtable[ch]. See the header and the source
3453 for the SilcHashTable API.
3455 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3457 * Merged dotconf version 1.0.2 into lib/dotconf.
3459 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3461 * Do not compile anything in lib/silcsim/* if the SIM support
3462 is not enabled. The tree should now compile without problems
3465 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3467 * Compiled the SILC under cygwin. Compiled and tested briefly
3468 without problems. More tests needed. The SIMs didn't compile
3471 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3473 * Fixed possible crash in silc_get_username in the
3474 lib/silcutil/silcutil.c.
3476 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3478 * Fixed a va_arg in silc/client_ops.c.
3480 * Oops, RC5 routines were named AES and caused some problems
3481 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3483 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Added new SilcIDIP structure into the lib/silccore/id.h and
3486 replaced the old `ip' fields from all SILC ID's to that type.
3487 This is a step towards IPv6 support.
3489 The silc_id_get_len takes now the ID as an extra argument.
3490 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3491 both IPv4 and IPv6 based ID's.
3493 The affected files are lib/silccore/id.[ch] and other files
3494 around the tree using these routines.
3496 * Removed the ID length arguments in server from various
3497 silc_server_send_notify_* routines -> they are not needed
3500 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3502 * Fixed memory leak in silc_encode_pem_file in the file
3503 lib/silcutil/silcutil.c.
3505 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3507 * Check minor version as well in the SKE. Affected files are
3508 silcd/protocol.c and lib/silcclient/protocol.c.
3510 * Added --identifier option to the server so that an identifier
3511 can be when creating the public key for the server. Affected
3512 file is silcd/silcd.c.
3514 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3515 lib/silccrypt/silcpkcs.c.
3517 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3519 * Register default ciphers and stuff when using -C option with
3520 the server. Affected file sildc/silcd.c.
3522 * Put back the servers public key filename format, it is better
3523 than the new one. For now, the client keys are saved with the
3524 new filename format. The affected file silc/client_ops.c.
3526 * Implemented the Cipher API for the rest of the ciphers that
3527 did not implement it or implemented it the wrong way.
3529 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3531 * Register default ciphers and stuff when using the -S option
3532 in the client. Affected file silc/silc.c. Same also when
3533 creating new key pair with -C option.
3535 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3537 * Fixed the silc_verify_public_key client operation function to
3538 save the public keys differently. The fingerprint is now
3539 used as filename and not the hostname. This way also the
3540 client keys are saved uniquely and not with hostnames. The
3541 affected file is silc/client_ops.c.
3543 * Trimmed the silc_hash_fingerprint function to remove extra
3544 whitespaces from the end of the fingerprint. The affected
3545 file is lib/silccrypt/silchash.c.
3549 * Added silc_cipher_register_default function to register all
3550 default ciphers. It can be used when configuration files
3551 does not exist and the application does not want any specific
3552 ciphers in any specific order.
3554 The SilcDList is now used as silc_cipher_list dynamically
3555 allocated cipher list. Removed the static list all together
3556 and now all ciphers must be allocated to the dynamic list.
3557 The silc_cipher_alloc routine was changed to check only the
3560 All silc_cipher_* routines that used to return int returns
3563 The affected files lib/silccrypt/silccrypt.[ch].
3565 * The same thing was done to silc_hash_* as for silc_cipher_*
3566 routines. Affected files lib/silccrypt/silchash.[ch].
3568 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3569 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3570 Added also silc_pkcs_[un]register[_default] functions.
3571 Removed the data_context from the PKCS API.
3573 * Added silc_hmac_register_default function to register default
3574 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3575 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3576 to unregister all hmacs at once.
3578 * Register the default ciphers, hash functions, PKCSs and HMACs
3579 if client's configuration file does not exist. The affected
3582 * The client did not load the hash functions from the SIM
3583 modules at all. Added support for this. Affected file is
3584 silc/clientconfig.c.
3586 * When decoding public key with silc_pkcs_public_key_decode, check
3587 the supported algorithm only if PKCS are registered. Affected
3588 file lib/silccrypt/silcpkcs.c. The same was done with the
3589 silc_pkcs_private_key_decode.
3591 * Fixed the SILC List routines to keep the list always in order.
3592 It used to change the list's order when traversing the list but
3593 not it preserves the order. Affected file lib/trq/silclist.h.
3595 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3597 * Added the client library to use the SilcSocketConnection's
3598 reference counter (by silc_socket_dup) to prevent the bug that
3599 the socket object may be freed underneath async operation.
3601 * The name resolv library checking fixes in the configure.in.pre.
3604 * Created new version of the protocol drafts for future
3605 development. The -03 drafts are the ones that will be changed
3606 in the trunk now and the -02 will remain as they are.
3608 * Send list of CUMODE notifys to the router when announcing
3609 the channel users to the router. Affected file silcd/server.c.
3610 If the router receiving channel founder CUMODE for a channel
3611 that already has channel founder it will send CUMODE notify
3612 to the sender to remove the channel founder rights from the
3613 announced client. Affected file silcd/packet_receive.c.
3615 * The CUMODE notify may now use Server ID as well as the entity
3616 who changes the mode. Updated protocool specs.
3618 * Updated INSTALL and README files.
3620 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * New web pages in the http://silc.pspt.fi. The pages was
3627 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3629 * Implemented the [DenyConnectin] config section in the server.
3630 Added silc_server_config_denied_conn to check whether incoming
3631 connection is denied. Affected file silcd/serverconfig.[ch].
3633 * Do not check the ports when checking the incoming configuration
3634 data if the port is 0, meaning any. Affected file is
3635 silcd/serverconfig.c.
3637 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3639 * Fixed buffer overflow in silc_string_compare in the file
3640 lib/silcutil/silcutil.c.
3642 * Fixed double free in silc_server_command_leave in the file
3645 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3647 * Fixed the version checking in the server. Affected file is
3650 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Fixed the configuration data fetching when accepting new
3653 connections in the server. Affected file silcd/server.c.
3655 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3657 * Added `sender_entry' argument to the function
3658 silc_server_packet_relay_to_channel so that we can check
3659 whether some destination actually belongs to the same route
3660 the sender belongs (ie, we must not resend the packet to the
3661 sender). Affected file silcd/packet_send.[ch].
3663 * Added `servername' field to the SilcClientEntry in the server
3664 to hold the name of the server where client is from. Affected
3665 file is silcd/idlist.h.
3667 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3669 * Moved the channel message encrypting in the router betwen
3670 router connections from silc_server_channel_message to the
3671 silc_server_packet_relay_to_channel since we want to check
3672 whether we have anybody channel before encrypting anything.
3673 Affected files silcd/packet_[receive/send].c.
3675 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3677 * Fixed the [AdminConnection] server config section to support
3678 multiple entries. Affected file silcd/serverconfig.c.
3680 * Added support into the server to check the validity of the
3681 incoming connection before executing any KE or authentication
3684 * The connection configuration is now saved to the KE and
3685 connection auth protocol contexts and not fetched anymore in
3686 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3688 * The local hosts listenning address and port is also resolved
3689 now when starting the server. We want to have the socket object
3690 to include the real address and port for the listener. Added
3691 new function silc_net_check_local_by_sock into the files
3692 lib/silcutil/silcnet.[ch].
3694 * Fixed a broadcast bug in server -> do not broadcast if we
3697 * Fixed a routing bug. Do not route broadcast packets ever.
3698 Broadcast packets must be processed always and not routed since
3699 they may be destined to some other host than yourself and thus
3700 would get routed without no good reason. Affected file is
3703 * Added function silc_server_config_is_primary_route to check
3704 whether primary router connection has been configured (a router
3705 configuration that we are initiating). If there is not, we
3706 will assume that there is only two routers in the SILC network
3707 and we will use the incoming router connection as our primary
3708 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3710 * Changed the order of the broadcasting. Broadcast _after_ the
3711 packet has been processed not before. Affected file is
3714 * Fixed a [ClientConnection] parsing bug. The port was never
3715 parsed correctly thus resulting to port 0. Affected file
3716 silcd/serverconfig.c.
3718 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3719 argument and did not set the broadcast packet flag. Affected
3720 file silcd/packet_send.c. Fixed same bug in the function
3721 silc_server_send_notify as well.
3723 * If we receive NEW_ID packet for our own ID in the server, ignore
3726 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3730 * Removed the nickname from the Private Message Payload.
3731 Updated the code and the protocol specs.
3733 * Updated protocol specs for submitting to the IETF.
3735 * Tweaked the Random Number Generator a bit. Affected file
3736 lib/silccrypt/silcrng.c. Exported a new function
3737 silc_rng_[global]_add_noise which can be used to add more
3740 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3742 * Do not parse packets with different timeout when protocol
3743 is active -> may cause problem with rekey. Affected file
3746 * When server receives signoff notify it must not create
3747 new channel key if the client is on any channels since the
3748 sender of the signoff notify will create it.
3750 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3752 * Added printing of error messages during SKE protocol from the
3753 failure packet sent by server during SKE. Affected file
3756 * Removed the client's failure_callback handling with timeout
3757 and handle it immediately when received.
3759 * The SKE library returned wrong type in SUCCESS and FAILURE
3760 packets. They must be 32 bit MSB not 16 bit MSB.
3762 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3764 * Ok, rewrote the logic of the re-key and now it seems to work.
3765 I tested it on high traffic with frequent re-keys without
3766 problems. Added hmac_receive (and renamed hmac to hmac_send)
3767 in SilcClientConnection in lib/silcclient/client.h and
3768 in SilcIDListData in silcd/idlist.h. Also, removed the
3769 SilcPacketParserContext's cipher and hmac fields as they are
3770 not needed anymore and actually caused some problems when
3771 the ciphers and hmac's changed underneath the packet parser.
3773 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * If re-key protocol is active then process the incoming packets
3776 synchronously since we must assure that icoming packets encrypted
3777 with the old key is processed before the new keys is set to
3778 use. This is true other packets than for REKEY packets.
3779 Affected file silcd/server.c. The same was done to client library
3780 as well, affected file lib/silcclient/client.c.
3782 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3784 * Fixed bug in client and server to accept the force send if
3785 the packet is send from silc_[server/client]_packet_process
3786 function. Otherwise the packets are never delivered, oops.
3788 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3790 * Disable force sending of packets when REKEY protocol is active.
3791 We must assure that no packet is sent directly when rekey is
3792 performed. All packets must be sent through packet queue.
3793 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3794 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3795 function is silc_[server/client]_packet_send_real to check
3798 * Replaced the SIM paths from example config files to
3799 /usr/local/modules. Also, make install creates now
3800 /usr/local/silc/logs directory to hold all the SILC server
3803 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Made the configure.in.pre work on Solaris. Patch by salo.
3807 * Made all ciphers compatible with non-x86 machines. Defined
3808 CBC mode macros into lib/silccrypt/ciphers_def.h.
3810 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3812 * Fixed the make install.
3814 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3816 * When MAC computation fails the silc_packet_decrypt returned 0
3817 even though it was supposed to return -1. Fixed this. The
3818 affected file is lib/silccore/silcpacket.c.
3820 * Do not replace the config files in /etc/silc (in make install)
3821 if they already exist. Affected file ./Makefile.am.
3823 * Do not send re-key packets immediately but through packet queue.
3824 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3826 * Changed silc_net_check_host_by_sock to return FALSE if the
3827 IP/DNS could not be resolved. Though, it returns the IP address
3828 now even if it could not resolve it (but returns also FALSE).
3829 Affected file lib/silcutil/silcnet.[ch].
3831 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Added silc_pkcs_decode_identifier to decode the public key's
3834 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3835 Added also silc_pkcs_free_identifier. Added also new context
3836 SilcPublicKeyIdentifier.
3838 * Added -S option to the silc client. It is used to dump the
3839 contents of the specified public key file.
3841 * Changed the PKCS api to return the public key length when
3842 setting the public key.
3844 * Fixed a fatal bug in the public and private key file loading.
3845 Affected file lib/silccrypt/silcpkcs.c.
3847 * Execute the packet parsing for client with zero (0) timeout
3848 if the protocol is active. Affected file silcd/server.c.
3850 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3852 * Made the key generation options to the silcd program. Added
3853 -C option, equivalent to client's option.
3855 * Added new [ServerKeys] config section to the server. It
3856 configures the server's public and private key.
3858 * Defined generic Public Key Payload into the protocol
3859 specification to send specific type of public keys and
3862 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3863 public key or certificate.
3865 * Implemented the GETKEY command to the server and to the
3866 client library and on user interface.
3868 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3870 * Made preliminary `make install' work.
3872 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3874 * Added SilcServerRekey context into silcd/idlist.h.
3876 * Added the PFS support as defined in the specification to the
3877 SKE protocol. Affected files lib/silcske/*.c.
3879 * Added `ske_group' field to the SilcServerRekey context to hold
3880 the number of the SKE group that is used with PFS in re-key.
3881 Affected file silcd/idlist.h.
3883 * Added PFS re-key support to the server. Affected file is
3886 * Added silc_protocol_cancel to cancel execution of the next
3887 state of the protocol. Affected file is
3888 lib/silccore/silcprotocol.[ch].
3890 * Added the re-key support with and without PFS to the client
3891 library. Re-key is performed once in an hour, by default.
3893 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3894 Added silc_client_rekey_callback and silc_client_rekey_final.
3895 Affected files are lib/silcclient/protocol.[ch] and
3896 lib/silcclient/client.[ch].
3898 * Removed the `hmac_key' and `hmac_key_len' fields from the
3899 SilcClientConnection structure; not needed. Affected file is
3900 lib/silcclient/client.h.
3904 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3906 * Do not ask whether user wants to use the negotiated private key
3907 for private messages, just use it. Affected file is
3908 silc/local_command.c.
3910 * Added `send_enc_key' and `enc_key_len' fields to the
3911 SilcIDListData structure since they are needed in the re-key
3912 phase. Affected file is silcd/idlist.[ch].
3914 * Implemented the simple re-key protocol into the server.
3915 Affected files silcd/server.c and silcd/protocol.[ch]. The
3916 re-key will be performed once in an hour, by default.
3918 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3919 Added silc_server_rekey, silc_server_rekey_callback and
3920 silc_server_rekey_final.
3922 * Removed Tunneled flag from the protocol. Updated the code
3923 and the specifications.
3925 * Adde `pfs' field to the SilcIDListData to indicate whether
3926 the PFS is to be performed in the re-key. Affected file is
3929 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3931 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3932 int64 of at least the xintXX size. If void * is less that 4
3933 bytes uint32 * will be used. Defined bool as boolean.
3935 * Changed _ALL_ unsigned long and unsigned int to uint32,
3936 unsgined short to uint16 in the source tree.
3938 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3939 not handle clients that has entry->data.registered == FALSE.
3940 They are not in the network anymore. Affected file is
3943 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3945 * Implemented the sending of the SERVER_SIGNOFF notify in the
3946 server. Affected file is silcd/server.c.
3948 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3949 Added also silc_notify_payload_encode_args into the
3950 lib/silccore/silcnotify.[ch].
3952 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3953 Affected file silcd/packet_receive.c.
3955 * Implemented the SERVER_SIGNOFF notify handling in the client
3956 library. Affected file lib/silcclient/client_notify.c. Also,
3957 implemnted the printing of the SERVER_SIGNOFF info to the
3958 application. Affected file silc/client_ops.c.
3960 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3961 if the deleting was successful. Affected file silcd/idlist.[ch].
3963 * Added support for public key authentication in the connection
3964 authentication protocol in the client library. Affected file
3965 lib/silcclient/protocol.c.
3967 * Changed the server's silc_idlist_get_clients_by_* interface
3968 to support already allocated array so that new entries may be
3969 added to pre-allocated array. Affected file silcd/idlist.[ch].
3970 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3971 and command replies.
3973 * All command reply functions in the server now calls the
3974 pending command callback even if error occured. This way the
3975 error will be delivered to the client as well. Affected files
3976 silcd/command.c and silcd/command_reply.c.
3978 * Fixed INFO command to return local server's info if no server
3979 was provided. Affected file lib/silcclient/command.c.
3981 * Removed RESTART command for good. Updated the code and the
3984 * Rewrote parts of the task system. It is a bit simpler now.
3985 Removed unsued task priorities. The affected files are
3986 lib/silcutil/silctask.[ch].
3988 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3990 * Moved the USERS printing from the library to the application.
3991 Affected files lib/silcclient/command.c and silc/client_ops.c.
3993 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3997 * Added channel key re-key support. The re-key is perfomed
3998 only by the router and is done once in an hour. Added `rekey'
3999 field to the SilcChannelEntry in the server. Affected files
4000 silcd/server.c and silcd/idlist.h.
4002 * Added silc_task_unregister_by_context into the file
4003 lib/silcutil/silctask.[ch].
4005 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4007 * Added SILC_UMODE_GONE mode to indicate when the client is not
4008 present in the SILC network. Added also support to the local
4009 command AWAY that will set this mode. Added support of showing
4010 "xxx is gone" in WHOIS command. The USERS command shows the
4011 gone status as well.
4013 * Fixed setting server and router operator privileges in the
4014 server's UMODE command. Affected file silcd/command.c.
4016 * Merged the SKE KE1 and KE2 payloads into one payload. The
4017 new KE payload is equivalent to the old KE2 payload.
4019 Cleaned up the SKE Start Payload parsing. It now uses the
4020 simple buffer unformatting to do the parsing. A lot faster
4023 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4024 to the SKE that is used to indicate whether both of the SKE
4025 parties should perform authentication. By default only the
4026 responder performs authentication. By setting this flag also
4027 the initiator must do authentication. By default it is unset
4028 since in normal SKE case, client to server connection, only
4029 the responder should do authentication. When doing SKE between
4030 two clients both should perform authentication. Updated the
4031 code and the protocol specs.
4033 * A little fix to IDENTIFY command in the server. Search the
4034 client first by hash not nickname. Affected file is
4037 * Fixed the silc_client_close_connection to support closing
4038 the client to client connections wihtout deleting too much
4039 data. Affected file lib/silcclient/client.c.
4041 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4042 are received if protocol used to be active but is not anymore
4043 the application would crash due to NULL pointer dereference.
4044 Affected files silcd/server.c and lib/silcclient/client.c.
4046 * Added `hash' field to the SilcClientConnection to include
4047 the hash function negotiated in the SKE protocol.
4049 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4050 to set the channel founder authentication data. A client can
4051 claim the founder rights later by providing the authentication
4052 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4053 This way the channel founder can regain the channel founder
4054 privileges even it is left the channel. This works only on
4055 local server and the client must be connected to the same
4056 server to be able to regain the founder rights. Updated the
4057 protocol specs accordingly.
4059 Added support to the CMODE command in the client to set the
4060 founder auth data. Read the README to see how to set it.
4062 Added support to the CUMODE command to claim the founder
4063 rights. Read the README to see how to do it.
4065 Added support for the founder authentication to the Channel
4066 Entry in the server. Affected file silcd/idlist.h.
4068 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4069 server's CMODE command. Affected file silcd/command.c.
4071 * Added the following new functions into lib/silccore/silcauth.[ch]:
4072 silc_auth_get_method and silc_auth_get_data.
4074 * The server now saves the remote hosts public key to the
4075 SilcIDListData pointer. Affected file silcd/protocol.c.
4077 * The normal server now does not remove the channel entry from
4078 the cache if the founder authentication data is set. It used
4079 to remove it if the founder was the last one on the channel on
4080 the server and left the channel. The auth data is saved and
4081 if the channel is re-joined later the old entry is used with
4082 the old auth data. Affected files silcd/command_reply.c and
4085 * Removed the `pkcs' field from the SilcIDListData structure
4086 in the server; it is not used. Affected file silcd/idlist.h.
4088 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4090 * Fixed packet processing on slow links. Partial packets were
4091 never re-processed because the incoming data buffer was cleared
4092 by the application. Application must not directly clear the
4093 sock->inbuf, the packet processing routines handle it. Fixed
4094 this in client library and in server.
4096 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4098 * Fixed the WHOIS and IDENTIFY send reply function to really
4099 check whether to send list or just one entry. Affected file
4102 * Cleaned up the LEAVE command's channel key distribution. The
4103 affected file silcd/command.c.
4105 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4106 can enforce the channel mode as well. In that case the ID
4107 includes the ID of the server. The code now enforces the
4108 mode change if the router have different mode than the server.
4110 * The notify client operation with CMODE_CHANGE notify can now
4111 return NULL client_entry pointer if the CMODE was not changed
4112 by client. Application must check for this.
4114 * Added <Server ID> argument to INFO command to support server
4115 info fetching by Server ID.
4117 * Added silc_server_announce_get_channel_users to get assembled
4118 packets of channel users of the specified channel. Affected
4119 file silcd/server.[ch].
4121 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4122 was freed underneath the ID Cache.
4124 * Re-announce clients when the server received CHANNEL_CHANGE
4125 notify from the router. Affected file silcd/packet_send.c.
4127 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4129 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4130 crashed since it did not handle the fact that there is no cipher
4131 called "3" and didn't check the error condition. Now fixed.
4133 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4134 flag. It can be used to send message requests.
4136 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Implemented the RESTART command in the client.
4140 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4141 notice type messages. Added notice printing to the user
4144 * The channel keys are not re-generated if the channel's mode
4145 is PRIVKEY, ie private key on the channel exists. Affected
4146 files silcd/server.c and silcd/command.c.
4148 * Fixed a little bug in channel message delivery when channel
4149 private keys are set in the server. Affected file is
4150 silcd/packet_send.c.
4152 * Changed the setting on channel->on_channel = TRUE from the
4153 silc_client_save_channel_key to the JOIN command reply. The
4154 key payload is not received if the private channel key is set.
4155 Affected file lib/silcclient/command_reply.c and the
4156 lib/silcclient/client_channel.c.
4158 * When the CMODE_CHANGE notify is sent and the channel private
4159 key mode is removed the channel key must be re-generated in
4160 other cells as well. Added this support for the router in the
4161 silcd/packet_receive.c.
4163 * Added new local command NOTICE to send notice message on
4164 channel. Affected file silc/local_command.[ch].
4166 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Added new local command ME to the client. It is used to send
4169 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4170 some action. Affected file silc/local_command.[ch].
4172 * Changed channel_message and private_message client operations
4173 to deliver the message flags to the application. Added also
4174 the `flags' arguments to the silc_client_send_channel_message
4175 and silc_client_send_private_message functions. Affected file
4178 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4180 * Redefined the Private Message Payload to support private message
4181 keys and to support the new private message flags. Updated
4182 the protocol specs. Flags makes it possible to have for example
4183 CTCP style messages.
4185 * Added new type SilcPrivateMessagePayload and defined an API
4186 for it in the lib/silcclient/silcprivate.[ch].
4188 * Tested private message private keys successfully. Tested the
4189 private message key set, unset and list commands with the new
4192 * Redefined the Channel Message Payload to include the channel
4193 message flags (equal with private message flags) to support
4194 for example CTCP style messages.
4196 * Defined some of the message (for channel and private message)
4197 flags. Updated the protocol specs and added the flags to the
4198 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4200 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4202 * Added SilcKeyAgreementStatus type to the key agreement routines
4203 to indicate the current status and error if one occured.
4204 The status types are defined in the lib/silcclient/silcapi.h.
4206 * Added new local command KEY that is used to set and unset private
4207 keys for channels, set and unset private keys for private messages
4208 with remote clients and to send key agreement requests and
4209 negotiate the key agreement protocol with remote client. The
4210 key agreement is supported only to negotiate private message keys,
4211 it currently cannot be used to negotiate private keys for channels,
4212 as it is not convenient for that purpose.
4214 * Fixed a minor pending callback setting bug in the function
4215 silc_client_get_client_by_id_resolve, now the function works.
4216 Affected file lib/silcclient/idlist.c.
4218 * Added function silc_net_get_local_port to get local bound
4219 port by socket. Added to lib/silcutil/silcnet.[ch].
4221 * Added `sockets' and `sockets_count' fields to the SilcClient
4222 object. They hold the sockets of the listenning sockets in
4223 the client. Listenning sockets may be for example the key
4224 agreement server. Affected file lib/silcclient/client.[ch].
4225 Added functions the silc_client_add_socket and the
4226 silc_client_del_socket. They are exported to the application
4229 * Added ~./silc/clientkeys to support other client's public keys.
4231 * Renamed verify_server_key client operation to verify_public_key
4232 and added one argument to indicate the type of the connection
4233 (server, client etc.).
4235 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4237 * Added silc_server_connection_auth_request to handle the
4238 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4239 silcd/packet_receive.[ch].
4241 * Added silc_server_send_connection_auth_request into the
4242 silcd/packet_send.c to send the connection auth request packet.
4244 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4247 * Fixed the public key authentication in responder side in the
4248 server. The `auth_data' pointer includes the SilcPublicKey
4249 not the path to the public key. Affected file silcd/protocol.c.
4251 * Implemented the public key authentication in the initiator side
4252 in the server. Affected file silcd/protocol.c.
4254 * Removed the [RedirectClient] config section from the server
4255 configuration. Is not needed and I don't want to implement it.
4257 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4259 * Cleaned up the CMODE command in the server. It now works
4260 correctly and supports all the modes defined in the protocol.
4261 Affected file is silcd/command.c.
4263 * Added `hmac_name' field to the SilcChannelEntry in the server
4264 to hold the default HMAC of the channel. It can be set when
4265 creating the channel (with JOIN command). Affected files
4268 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4269 type to indicate the change of the current cipher and hmac
4270 on the channel. Client can safely ignore the <cipher> argument
4271 (if it chooses to do so) since the CHANNEL_KEY packet will
4272 force the channel key change anyway. The <hmac> argument is
4273 important since the client is responsible of setting the new
4274 HMAC and the hmac key into use.
4276 * Fixed the CMODE command in the client library as well.
4278 * Tested CMODE command in router environment successfully.
4280 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4282 * Show the version of the remote client (or server) when connecting
4283 to the server. It is logged to the log file. Affected file
4284 is silcd/protocol.c.
4286 * Fixed the KILLED notify handling in the client library. The
4287 client must be removed from all channels when receiving the
4290 Also, do not remove the client entry when giving the KILL
4291 command but when the KILLED notify is received.
4293 * Removed silc_idlist_find_client_by_nickname from the server.
4294 Not needed anymore. Affected files silcd/idlist.[ch].
4296 * Implemented the CHANNEL_CHANGE notify type handling to the
4297 server. Affected file silcd/server.c.
4301 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4303 * Added silc_server_send_notify_invite to send the INVITE
4304 notify between routers.
4306 * Implemented the INVITE command correctly to the server.
4308 * Implemented the INVITE notify type handling in the server.
4310 * Implemented the INVITE command to the client library and on the
4313 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4315 * Added function silc_server_get_client_resolve to find the
4316 client entry by ID from all ID lists and then resolve it
4317 (using WHOIS) if it cannot be found. Affected file is
4320 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Implemented the BAN command to the client library.
4324 * The JOIN command in the server now checks the invite list
4327 * Changed the silc_command_reply_payload_encode_va and the
4328 silc_command_payload_encode_va to support that if argument is
4329 NULL it ignores and checks the next argument. Affected file
4330 lib/silccore/silccommand.c.
4332 * Added silc_server_send_notify_ban to send the BAN notify
4333 type between routers.
4335 * Chaned the silc_notify_payload_encode to support that if
4336 argument is NULL it ignores and checks the next argument.
4337 Affected file lib/silccore/silcnotify.c.
4339 * Tested ban lists in router environment successfully.
4341 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Implemented BAN command to the server, in silcd/command.[ch].
4345 * Removed the BAN and INVITE_LIST modes from the CMODE command
4348 * Added function silc_string_match to regex match two strings.
4349 Affected files lib/silcutil/silcutil.[ch].
4351 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * Redefined parts of the SilcChannelEntry in the server to support
4354 the new ban and invite lists.
4356 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4358 * Redefined the INVITE command. The same command can be used to
4359 invite individuals to the channel but also to manage the invite
4360 list of the channel (to add to and remove from the invite list).
4361 Updated the protocol specs.
4363 * Added new command SILC_COMMAND_BAN that can be used to manage
4364 the ban list of the channel. Updated the protocol specs.
4366 * Removed the channel modes: the SILC_CMODE_BAN and the
4367 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4368 in the CMODE command. The equivalent features are now available
4369 using INVITE and BAN commands. Updated the protocol specs.
4371 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4372 in the network about change in the current ban list. The notify
4373 type is not used by the client.
4375 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4376 support the invite lists.
4378 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4380 * Added new function silc_string_regexify that converts string
4381 including wildcard characters into regex string that can
4382 be used by the GNU regex library. Added into the file
4383 lib/silcutil/silcutil.[ch].
4385 Added silc_string_regex_combine to combine to regex strings
4386 into one so that they can be used as one regex string by
4387 the GNU regex library. Added into the file
4388 lib/silcutil/silcutil.[ch].
4390 Added silc_string_regex_match to match two strings. It returns
4391 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4393 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Imported GNU regex to the soruce tree into lib/contrib.
4396 Fixed some compiler warning from the regex.c.
4398 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4400 * Fixed MOTD command in the server to work in router environment.
4402 * Fixed the MOTD command in the client library to support
4403 the server argument in the command.
4405 * Added `nickname_len' argument to the silc_idlist_add_client
4406 in the server, as the `nickname' argument may be binary data
4409 * Added silc_idlist_get_channels to return all channels from
4412 * Implemented LIST command to the server. Affected file is
4415 * Implemented the LIST command to the client library and on the
4418 * Added [<user count>] argument to the LIST command reply.
4419 With private channels the user count is not shown.
4421 * Updated TODO and README.
4423 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4425 * The client entry's data.registered must be TRUE even with
4426 global client entry on global client list. The data.registered
4427 is used to check whether the client is anymore in the network,
4428 for example with WHOWAS command so it must be valid.
4430 * Fixed the WHOWAS command in the server. It now actually works
4431 in router environment. Added function into silcd/command_reply.c
4432 silc_server_command_reply_whowas_save.
4434 * Added silc_idlist_purge function to the silcd/idlist.c
4435 to periodically purge the ID Cache.
4437 * Fixed INFO command in the server. It works now in router
4438 environment. Added <server name> argument to the INFO command
4439 reply. Updated the protocol specs.
4441 * Fixed minor bug in silc_idcache_purge to not purge if the
4442 expire value is zero.
4444 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4445 they were buggy because of the WHOWAS information.
4447 * Fixed local command MSG to handle the async resolving of
4448 the remote client properly. It used to fail the first MSG.
4449 Affected file silc/local_command.c.
4451 * Added `data_len' field to SilcIDCache context.
4453 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * Update TODO. Todo in commands in the server.
4457 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4459 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4460 used by routers as broadcast packet to inform other routers
4461 about the changed user mode.
4463 Implemented the notify handling in the server. Affected file is
4464 silcd/packet_receive.c. Added the function
4465 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4467 * Added new generic Channel Payload and deprecated the New Channel
4468 Payload. The New Channel Payload is now the generic Channel
4471 * Added new argument `mode' to the silc_server_send_new_channel
4472 as it is required in the Channel Payload now.
4474 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4475 and created a new and real SilChannelPayload to represent the
4476 new generic Channel Payload. Implemented the encode/decode
4477 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4479 * Added silc_server_get_client_channel_list to return the list
4480 of channels the client has joined for WHOIS command reply.
4481 Affected file silcd/server.[ch].
4483 * Implemented the channel list sending in the WHOIS command reply
4484 in server and in the client.
4486 Implemented the channel list displaying on the user interface
4487 as well. Affected file silc/client_ops.c.
4489 * Added silc_channel_payload_parse_list to parse list of Channel
4490 Payloads. It returns SilcDList list of SilcChannelPayloads.
4491 Client for example can use this function to parse the list of
4492 channels it receives in the WHOIS command reply. The caller
4493 must free the list by calling silc_channel_payload_list_free.
4494 Affected files lib/silccore/silcchannel.[ch].
4496 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * Added one new argument <user mode> to the WHOIS command reply
4499 to return the mode of the user in SILC. Updated the protocol
4502 Implemented it to the server and client.
4504 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * Fixed the mode printing on the user interface on joining.
4507 Affected file silc/client_ops.c.
4509 * Implemented the UMODE command and user modes in general to the
4510 client library and to the user interface.
4512 * Implemented the UMODE command to the server.
4514 * The server now sends UNKNOWN_COMMAND error status if client sends
4515 unknown command. Affected file silcd/command.c.
4517 * All server commands now handle the command identifier the right
4518 way when sending the command reply to the client. The client can
4519 use to identify the command replies with the identifier.
4521 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4523 * Added silc_server_get_client_route to resolve the route to
4524 the client indicated by the client ID. Affected file is
4527 * Added silc_server_relay_packet as general function to relay
4528 packet to arbitrary destination. This deprecates functions
4529 like _send_private_message_key, _relay_notify etc. Affected
4530 file is silcd/packet_send.[ch].
4532 Removed silc_server_send_key_agreement,
4533 silc_server_send_private_message_key and
4534 silc_server_packet_relay_notify functions from the file
4535 silcd/packet_send.[ch].
4539 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4540 server. Affected file silcd/packet_receive.[ch].
4542 * Implemented the KILL command to the client. Implemented the
4543 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4544 Affected files lib/silcclient/command[_reply].c and
4545 lib/silcclient/client_notify.c. Implemented the KILL notify
4546 printing in the user inteface.
4548 * Fixed a lot silc_parse_nick memory leaks from the client
4549 library in the file lib/silcclient/command.c.
4551 * Changed the silc_server_send_notify_on_channels's `sender'
4552 argument from SilcSocketConnection to SilcClientEntry to
4553 check the sender as entry and not as connection object and not
4554 to send to the client provided as argument. The affected file
4555 is silcd/packet_send.[ch].
4557 * The notify packets that are destined directly to the client used
4558 to not to be processed by the server. Now changed that and the
4559 server processes all notify packets. After relaying the packet
4560 to the client the notify packet is processed in the server.
4562 * The silc_server_free_client_data now checks whether there is
4563 pending outgoing traffic for the client and purges the data to
4564 the network before removing the client entry.
4566 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4568 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4569 an client is killed from the SILC Network. Updated the protocol
4572 Added new function silc_server_send_notify_killed to the
4573 silcd/packet_send.[ch].
4575 * Added function silc_server_packet_relay_notify to relay notify
4576 packets that are destined directly to a client. In this case
4577 the server does not process the notify packets but merely relays
4578 it to the client. Affected file silcd/packet_send.[ch].
4580 Added also silc_server_packet_process_relay_notify to check
4581 whereto relay the notify. Affected file is
4582 silcd/packet_receive.[ch].
4584 * Implemented the KILL command to the server.
4588 * Added the backup schema desgined last fall to the protocol
4589 specs for everyone to see. The specification is in the
4590 *-spec-xx.txt draft and the packet type definitions for the
4591 backup routers is in *-pp-xx.txt draft. Thusly, added also
4592 new packet type SILC_PACKET_CELL_ROUTERS.
4594 * A big security problem in the implementation discovered. The
4595 signoff of an client did not cause new channel key generation
4596 which it of course should've done. The channel keys must be
4597 always re-generated when client leaves (or signoffs) the channel.
4598 The silc_server_remove_from_channels funtion now handles
4599 the channel key re-generation.
4601 * Added `sender' argument to the silc_server_send_notify_on_channels
4602 to not to send the client provided as argument. Affected file
4603 silcd/packet_send.[ch].
4605 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4607 * Implemented OPER and SILCOPER commands into the server and
4610 * Added silc_auth_verify and silc_auth_verify_data to verify
4611 the authentication directly from the authentication payload.
4612 It supports verifying both passphrase and public key based
4613 authentication. Affected file lib/silccore/silcauth.[ch].
4615 * Added `hash' field to the SilcIDListData structure. It is the
4616 hash negotiated in the SKE protocol. Affected file is
4619 * Slight redesigning of the SilcAuthPayload handling routines.
4620 Do not send SilcPKCS but SilcPublicKey as argument.
4622 * Implemented the public key authentication support to the
4623 serverconfig. The public key is loaded from the provided path
4624 and saved as authentication data to void * pointer. Thus,
4625 changed the unsigned char *auth_data to void *auth_data;
4627 * Fixed SHUTDOWN command to send the reply before the server
4628 is shutdown. :) Affected file silcd/command.c.
4630 * Fixed fatal bug in CONNECT command. The hostname was invalid
4631 memory and server crashed. Affected file silcd/command.c.
4633 * Fixed fatal bug in CLOSE command. The server_entry became
4634 invalid but was referenced later in the command. Affected file
4637 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4639 * Fixed fatal bug in failure packet handling. Server ignored
4640 the failure and thus crashed when it came.
4644 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4646 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4647 that the command may be executed only once in (about) 2 seconds.
4648 The old SILC_CF_LAG flag is same but allows command bursts up
4649 to five before limiting.
4651 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4652 server code. Various commands now includes the CF_LAG_STRICT
4653 flag to disallow any kind of miss-use of the command.
4655 * Fixed the silc_buffer_unformat to not to allocate any data
4656 if the length of the data is zero. It used to allocate the
4657 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4659 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * Changed the format of AdminConnection configuration section
4662 in the server. Added username of the admin to the format.
4663 Affected files silcd/serverconfig.[ch].
4665 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4666 to return admin configuration data by host, username and/or
4669 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4671 * Implemented WHOWAS command to the server. Added the functions:
4673 silc_server_command_whowas_parse,
4674 silc_server_command_whowas_send_reply,
4675 silc_server_command_whowas_from_client and
4676 silc_server_command_whowas_from_server
4678 * Added <Client ID> argument to the WHOWAS command reply. Updated
4679 the protocol specs accordingly.
4681 * Implemented WHOWAS command and command_reply to the client
4684 Implemented the WHOWAS printing on the user interface.
4686 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4688 * Added new argument to the WHOWAS command reply, the real name.
4689 It is an optional argument. Updated the protocol specs.
4691 * Added SilcIDCacheDestructor callback that is registered when
4692 the SilcIDCache is allocated. The callback is called when
4693 an cache entry in the ID Cache expires, or is purged from the
4694 cache. Added into lib/silccore/idcache.[ch].
4696 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4697 to destruct the client entries when the cache entry expires.
4698 Other ID Cache's in server and in the client library ignores
4701 * If the ID Cache entry's `expire' field is zero then the entry
4702 never expires. Added boolean `expire' argument to the
4703 silc_idcache_add function in the lib/silccore/idcache.[ch].
4704 If it is TRUE the default expiry value is used.
4706 * Added silc_server_free_client_data_timeout that is registered
4707 when client disconnects. By default for 5 minutes we preserve
4708 the client entry for history - for WHOWAS command.
4710 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Added support to the server to enforce that commands are not
4713 executed more than once in 2 seconds. If server receives
4714 commands from client more frequently, timeout is registered
4715 to process the commands. Affected file silcd/command.c.
4716 Added new function silc_server_command_process_timeout.
4718 * Changed NICK_NOTIFY handling in client library to check that
4719 if the client's nickname was changed, so there is no need to
4720 resolve anything from the server.
4722 * Removed error printing from the WHOIS and IDENTIFY commands.
4723 If error occurs then it is ignored silently in the client library.
4724 The application, however, may map the received error to
4725 human readable error string. The application currently maps
4726 the NO_SUCH_NICKNAME error to string.
4728 * Made the command status message public to the application. Moved
4729 them from lib/silcclient/command_reply.c to
4730 lib/silcclient/command_reply.h. The application can map the
4731 received command status to the string with the
4732 silc_client_command_status_message function.
4734 * Added check to the server to check that client's ID is same
4735 as the Source ID in the packet the client sent. They must
4738 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Added dist-bzip hook to the Makefile.am to make bzip2
4741 compressed distributions.
4743 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4745 * Server now enforces the maximum length for the nickname and
4746 the channel as protocol specification dictates. 128 bytes for
4747 nickname and 256 bytes for channel name.
4749 * Moved the WHOIS printing to the application. The client libary
4750 does not print out the WHOIS information anymore, the application
4751 must do it. Renamed silc_client_command_reply_whois_print to
4752 the silc_client_command_reply_whois_save.
4754 The client's idle time is also sent to the application now, and
4755 the idle is shown on screen.
4757 * Added silc_client_command_reply_identify_save to save the
4758 received IDENTIFY entries.
4760 * Do not check for channel private keys in message sending and
4761 reception if the channel does not have the PRIVKEY mode set.
4762 Affected file lib/silclient/client_channel.c.
4764 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4766 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4767 just surfaced after chaning the JOIN procedure.
4769 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4771 * Added silc_client_get_clients_by_list to get client entries
4772 from Client ID list, that is returned for example by JOIN
4773 and USERS command replies. The application should use this
4774 function for example when JOIN command reply is received to
4775 resolve the clients already on the channel (library does not
4776 do that anymore as USERS command reply is not used in the JOIN
4777 procedure anymore). Affected files lib/silcclient/silcapi.h and
4778 lib/silcclient/idlist.c.
4780 * JOIN command reply and USERS command reply returns now SilcBuffer
4781 pointers instead of unsigned char pointers when returning
4782 the client list and mode list.
4784 * Added <Client ID> argument to the JOIN command reply, mainly
4785 for the server to identify for which client the command was
4786 originally sent. Updated protocol specs accordingly.
4788 * Added SilcDlist private_key pointer to the SilcChannelEntry
4789 in the client to support the channel private keys. Affected
4790 file is lib/silcclient/idlist.h.
4792 * Added SilcChannelPrivateKey argument to the function
4793 silc_client_send_channel_message so that application can choose
4794 to use specific private ke if it wants to. If it is not provided,
4795 the normal channel key is used, unless private keys are set.
4796 In this case the first (key that was added first) is used
4797 as the encryption key.
4799 * Implemented the support for channel private key handling.
4800 Implemented the following functions:
4802 silc_client_add_channel_private_key,
4803 silc_client_del_channel_private_keys,
4804 silc_client_del_channel_private_key,
4805 silc_client_list_channel_private_keys and
4806 silc_client_free_channel_private_keys
4808 Affected file lib/silcclient/client_channel.c.
4810 * Added the support for the private keys in the channel message
4811 sending and encryption and in the message reception and
4812 decryption. Affected funtions are
4813 silc_client_send_channel_message and silc_client_channel_message.
4815 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4817 * Added SKE's key verify callback to the client library's
4818 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4820 * Removed the statement that server (or router) must send USERS
4821 command reply when joining to the channel so that the client
4822 knows who are on the channel. Instead, the client list and
4823 client's mode list is now sent in the JOIN command reply to the
4824 client who joined channel. This is better solution.
4826 * Added function silc_server_get_users_on_channel and function
4827 silc_server_save_users_on_channel to the silcd/server.[ch].
4829 * Removed function silc_server_command_send_users from the
4832 * Do not show topic on the client library anymore. The topic is
4833 sent in the command reply notify to the application and the
4834 application must show the topic now.
4836 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Added client searching by nickname hash into the IDENTIFY and
4839 WHOIS commands in the server as they were clearly missing from
4840 them. Affected file is silcd/command.c.
4842 * Fixed a bug in private message receiving in the client library.
4843 The remote ID was freed and it wasn't supposed, now it is
4846 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4848 * Minor fix to the channel payload; allocate the data area, as it
4849 needs to be of specific length.
4851 * If the key agreement port is zero then the operating
4852 system will define the bound port. Affected files are
4853 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4855 * Added new function silc_channel_payload_decrypt into the file
4856 lib/silccore/silcchannel.[ch].
4858 * Moved the channel message etc, check from silc_packet_decrypt
4859 to applications. The library calls now a generic
4860 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4861 when the packet is either normal or special. This was done to
4862 allow more wide range of checking that was not allowed when
4863 the code was in library. Now applications can do virtually any
4864 checks to the packet and return to the library the decision how
4865 the packet should be processed. Affected files are
4866 lib/silccore/silcpacket.[ch].
4868 Added silc_server_packet_decrypt_check to the server and
4869 silc_client_packet_decrypt_check to the client library.
4871 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4872 to send with specified source and destination information.
4874 * Channel message delivery between routers was broken after the
4875 channel key distribution was fixed earlier. The channel key
4876 was used be to distributed to other routers as well which is not
4877 allowed by the protocol. Now this is fixed and channel keys
4878 really are cell specific and the channel message delivery between
4879 routers comply with the protocol specification.
4881 * Fixed various commands in server to check also the global list
4882 for the channel entry and not just the local list. The affected
4883 file silcd/command.c.
4885 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4887 * Added assert()s to buffer formatting and unformatting routines
4888 to assert (if --enable-debug) when error occurs. Affected
4889 file: lib/silcutil/silcbuffmt.c.
4891 * Changed to auto-reconnect to check whether the remote host is
4892 router and register the re-connect timeout if it is. It used
4893 to check that whether we are normal server, but router must do
4894 auto-reconnect with another router as well. Affected file
4897 * Removed the [<key len>] option from CMODE command as the cipher
4898 name decides the key length, nowadays. See the defined ciphers
4899 from the protocol specification.
4901 * Added [<hmac>] option to the CMODE command to define the HMAC
4902 for the channel. Added SILC_CMODE_HMAC channel mode.
4904 * Added [<hmac>] option for the JOIN command so that user can
4905 select which HMAC is used to compute the MACs of the channel
4908 * Added Hmac field to the Channel Message Payload. The integrity
4909 of plaintext channel messages are now protected by computing
4910 MAC of the message and attaching the MAC to the payload. The
4911 MAC is encrypted. Now, it is clear that this causes some
4912 overhead to the size of the packet but rationale for this is that
4913 now the receiver can verify whether the channel message decrypted
4914 correctly and also when private keys are set for the channel the
4915 receiver can decrypt the packet with several keys and check from
4916 the MAC which key decrypted the message correctly.
4918 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4919 lib/silccrypt/silccipher.[ch].
4921 * Added silc_hash_len to return the digest length into the
4922 lib/silcrypt/silchash.[ch].
4924 * Rewrote parts of Silc Channel Payload interface in the
4925 lib/silccore/silcchannel.[ch]. The encode function now also
4926 encrypts the packet and parse function decrypts it.
4928 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4930 * Fixed a minor formatting bug in the SKE's key material processing.
4931 It actually might have processed the keys wrong way resulting
4934 * Redefined the mandatory HMAC algorithms and added new algorithms.
4935 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4936 and hmac-md5 truncated to 96 bits. The mandatory is now
4937 hmac-sha1-96. Rest are optional (including the one that used
4938 to be mandatory). Rationale for this is that the truncated HMAC
4939 length is sufficient from security point of view and can actually
4940 make the attack against the HMAC harder. Also, the truncated
4941 HMAC causes less overhead to the packets. See the RFC2104 for
4944 * Added new [hmac] configuration section. The SKE used to use
4945 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4946 is of course wrong. The official names that must be proposed in
4947 the SKE are the ones defined in the protocol specification
4948 (hmac-sha1-96 for example). The user can configure any hmac
4949 using any hash function configured in the [hash] section. At
4950 least, the mandatory must be configured.
4952 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4954 * Added HMAC list to the SKE proposal list. It has now both
4955 hash algorithm list and HMAC list. This makes the protocol
4956 incompatible with previous versions. The SKE now seems to work
4957 the way it is supposed to work, for the first time actually.
4959 * Defined plain Hash algorithms to the protocol specification.
4962 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4964 * Implemented support for key agreement packets into the server.
4965 Added functions silc_server_key_agreement and
4966 silc_server_send_key_agreement. Other than these functions,
4967 server has nothing to do with this packet.
4969 * Added support for private message key packets into the server.
4970 Added functions silc_server_private_message_key and
4971 silc_server_send_private_message_key.
4975 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4976 called in the protocol's final callback instead in the END
4977 protocol state. This makes a little more sense and in the same
4978 time in client we can use the same protocol routines for normal
4979 key exchange and to key agreement packet handling as well.
4981 * Added to both client's and server's KE protocol context the
4982 SilcSKEKeyMaterial pointer to save the key material. We will
4983 bring the key material to the protocol's final callback by doing
4984 this. The final callback must free the key material.
4986 * Added SKE's packet_send callback into client's KE protocol
4987 context so that the caller can choose what packet sending function
4988 is used. This way we can use different packet sending when
4989 doing normal SKE when doing key agreement packet handling (in
4990 the key agreement packet handling we do not want to encrypt
4993 * Implemented the responder side of the key agreement routines
4994 in the client. The client can now bind to specified port and
4995 accept incoming key negotiation. The key material is passed
4996 to the application after the protocol is over.
4998 * Implemented the processing of incoming Key Agreement packet
4999 in the client. Added function silc_client_key_agreement to
5002 * Implemented the intiator side of the key agreement routines
5003 in the client. The client can now initiate key agreement with
5004 another remote client. The key material is passed to the
5005 application after the protocol is over.
5007 * Created client_keyagr.c to include all the key agreement
5010 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5011 SILC_TASK_CALLBACK except that it is not static.
5013 * Created client_notify.c and moved the Notify packet handling
5014 from the client.[ch] into that file.
5016 * Created client_prvmsg.c and moved all private message and
5017 private message key routines from the client.[ch] into that file.
5019 * Create client_channel.c and moved all channel message and
5020 channel private key routines from the client.[ch] into that file.
5022 * Changed silc_client_get_client_by_id_resolve to resolve with
5023 WHOIS command instead of IDENTIFY command, in the file
5024 lib/silclient/idlist.c.
5026 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5028 * Implemented the SKE's responder side to the Client library.
5030 * When FAILURE is received to the protocol do not trust it
5031 blindly. Register a timeout to wait whether the remote closes
5032 the connection as it should do it, only after that process the
5033 actual failure. This was changed to both client and server.
5035 * Added client_internal.h to include some of the structures
5036 there instead of client.h in lib/silcclient/.
5038 * Added function silc_task_unregister_by_callback to unregister
5039 timeouts by the callback function.
5041 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5043 * Some "Incomplete WHOIS info" errors has been appearing on the
5044 log files. Took away the entry->userinfo check from WHOIS
5045 reply sending. The entry->userinfo is now " " if client did not
5046 provide one. I thought this was fixed earlier but something
5047 is wrong still. Let's see if the error still appears.
5049 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Fixed a minor bug in the login when the channel key is
5052 re-generated in the server. It used to generate the key in
5053 wrong order and thus caused problems in the channel traffic.
5055 * Fixed a minor bug in channel key distsribution after
5056 KICK command. The key was not sent to the router even though
5059 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5061 * Added silc_ske_process_key_material_data as generic routine
5062 to process any key material as the SILC protocol dictates. The
5063 function is used by the actual SKE library but can be used by
5064 applications as well. This relates to the private message keys
5065 and the channel private keys since they must be processed the
5066 same way the normal SILC session keys. The protocol dictates
5067 this. Affected files: lib/silcske/silcske.[ch].
5069 Added also silc_ske_free_key_material to free the
5070 SilcSKEKeyMaterial structure.
5072 * Defined silc_cipher_set_key function to set the key for
5073 cipher without using the object's method function. The affected
5074 files: lib/silccrypt/silccipher.[ch].
5076 * Implemented silc silc_client_add_private_message_key,
5077 silc_client_add_private_message_key_ske,
5078 silc_client_del_private_message_key,
5079 silc_client_list_private_message_keys and
5080 silc_client_free_private_message_keys functions in the
5083 Added functions silc_client_send_private_message_key to send
5084 the Private Message Key payload and silc_client_private_message_key
5085 to handle incoming Private Message Key payload.
5087 * Added Cipher field to the Private Message Key payload to set
5088 the cipher to be used. If ignored, the default cipher defined
5089 in the SILC protocol (aes-256-cbc) is used.
5091 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5093 * Removed lib/silcclient/ops.h file.
5095 Redefined parts of the SILC Client Library API. Created new
5096 file silcapi.h that deprecates the ops.h file and defines the
5097 published Client Library API. Defined also private message key
5098 API and channel private key API into the file.
5100 This is the file that the application must include from the
5101 SILC Client Library. Other files need not be included by
5102 the application anymore.
5104 * Added new key_agreement client operation callback and also
5105 defined the Key Agreement library API for the application.
5107 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5110 is used by clients to request key negotiation between another
5111 client in the SILC network. If the negotiation is started it
5112 is performed using the SKE protocol. The result of the
5113 negotiation, the secret key material, can be used for example
5114 as private message key.
5116 Implemented the Key Agreement payload into the files
5117 lib/silccore/silauth.[ch].
5119 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5121 * Redefined ciphers for the SILC protocol. Added some new ciphers
5122 and defined the key lengths for the algorithms. Changed the
5123 code accordingly. The default key length is now 256 bits.
5125 * Fixed SKE key distribution function silc_ske_process_key_material
5126 when the key length is more than 128 bits. The default key
5127 length in SILC is now 256 bits.
5129 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5130 to indicate unsupported algorithm.
5132 * Renamed rijndael.c to aes.c and all functions as well.
5134 * Fixed a long standing channel key setting bug in client library.
5135 Weird that it has never surfaced before.
5137 * Fixed bug in channel deletion. If the entire channel is removed
5138 then it must also delete the references of the channel entry
5139 from the client's channel list as the client's channel entry and
5140 the channel's client entry share same memory.
5142 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5144 * Implemented CONNECT and SHUTDOWN commands in the client.
5146 * Implemented CLOSE command to the client.
5148 * Added the function silc_idlist_find_server_by_name into the
5149 files silcd/idlist.[ch].
5151 Added the function silc_idlist_find_server_by_conn into the
5152 files silcd/idlist.[ch].
5154 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5156 * DIE command was renamed to SHUTDOWN. Updated the both code
5159 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5160 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5162 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5165 * Added function silc_server_create_connection function to create
5166 connection to remote router. My server implementation actually
5167 does not allow router to connect to normal server (it expects
5168 that normal server always initiates the connection to the router)
5169 so the CONNECT command is only good for connecting to another
5172 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5174 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5175 or some other client was kicked from the channel.
5177 Implemented the handling of the notify type to both client
5180 Implemented silc_server_send_notify_kicked to send the KICKED
5181 notify. It is used to send it to the server's primary router.
5183 * Implemented the KICK command into server and client.
5185 * Added `query' argument to the silc_idlist_get_client function
5186 to indicate whether to query the client from server or not if
5189 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5190 to indicate that the client is not channel founder.
5194 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Removed the rng context from SilcPacketContext structure and
5197 changed that the packet routine uses the Global RNG API.
5199 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5201 * Added support for quit message that client can "leave" on the
5202 channel when it quits the SILC. It is ditributed inside the
5203 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5205 Added silc_server_free_client_data that will take the
5206 signoff message as argument.
5208 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5210 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5212 * Updated parts of the protocol specification to keep it up
5215 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5217 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5218 payloads in one packet.
5220 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5221 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5222 use now the new List flag.
5224 * Also deprecated the following packet types: REPLACE_ID,
5225 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5227 * Added list support for Notify packet in server.
5229 * Added silc_server_send_notify_channel_change to send the
5230 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5231 the silc_server_send_replace_id.
5233 * Added silc_server_send_notify_nick_change to send the
5234 NICK_CHANGE notify type. Deprecates the function
5235 silc_server_send_replace_id.
5237 * Added silc_server_send_notify_join to send the JOIN notify type.
5238 Deprecates the function silc_server_send_new_channel_user.
5240 * Added silc_server_send_notify_leave to send LEAVE notify type.
5241 Deprecates the function silc_server_send_remove_channel_user.
5243 * Added silc_server_send_notify_cmode and
5244 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5245 types. Deprecates the silc_server_send_set_mode function.
5247 * Added SERVER_SIGNOFF notify type to indicate that server has
5248 quit. This means that all clients on the channel from that
5249 server will drop. This can be also used when netsplit happens.
5251 Deprecated REMOVE_ID packet type since it is not needed anymore
5254 Added silc_server_send_notify_server_signoff to send the
5255 SERVER_SIGNOFF notify type. Deprecates the function
5256 silc_server_send_remove_id.
5258 Added also silc_server_send_notify_signoff to send the
5259 SIGNOFF notify type.
5261 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5262 SILC protocol from this day on. Changed the protocol
5263 specification as well.
5265 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5266 notify type. It is used between routers to notify about
5267 topic changes on a channel.
5269 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5272 * Partly updated the protocol specification to comply with the
5273 changes now made. It is still though a bit outdated.
5275 * The JOIN notify type now takes one extra argument <Channel ID>.
5276 The packet used to be destined to the channel but now the
5277 JOIN type may be sent as list thus it is impossible to
5278 destine it to any specific channel. By adding this argument
5279 it is again possible.
5281 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5283 * Added CREDITS file. The CHANGES and CREDITS file will appear
5284 in the distribution as well.
5286 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5288 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5289 types in the server's silcd/packet_receive.c.
5291 * Implemented CMODE and CUMODE to work in router environment.
5293 * Fixed minor encoding and decoding buglet from the
5294 lib/silccore/silcmode.c.
5296 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5299 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5301 * Changed all SilcConfigServer* and silc_config_server* to
5302 SilcServerConfig* and silc_server_config*, respectively.
5305 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Associated the ID (client or server ID) to the Authentication
5308 Payload to avoid any possibility of forging. Updated the
5309 protocol specification and the code accordingly.
5311 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5313 * The RSA key length is now save to the RsaKey context in the
5314 key generation process in lib/silccrypt/rsa.c. The key length
5315 is now used to figure out the maximum size of the block allowed
5316 to be encrypted/signed.
5318 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5319 is equivalent to the silc_mp_mp2bin but does not allocate any
5322 * Changed silc_mp_mp2bin API to take length argument. If it is
5323 non-zero then the buffer is allocated that large. If zero, then
5324 the size is approximated using silc_mp_sizeinbase, which however
5327 * Created Global RNG API which is global RNG that application can
5328 initialize. After initializing, any routine anywhere in the
5329 code (including library) can use RNG without allocating a new
5330 RNG object. This was done to allow this sort of use of the
5331 RNG in code that has no chance to allocate RNG object. All
5332 applications currently allocate this and many routines in the
5333 library use this. Affected file lib/silccrypt/silcrng.[ch].
5335 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5336 it to use the Global RNG API.
5338 * Defined Authentication Payload into protocol specification that
5339 is used during SILC session to authenticate entities. It is
5340 used for example by client to authenticate itself to the server
5341 to obtain server operator privileges.
5343 Implemented this payload into the lib/silccore/silcauth.[ch].
5344 Implemented also routines for public key based authentication
5345 as the new protocol specification dictates.
5347 Moved definitions of different authentication methods from
5348 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5350 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5351 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5352 silc_pkcs_verify_with_hash functions into the file
5353 lib/silccrypt/silcpkcs.[ch].
5355 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5357 * The client entry's userinfo pointer must be always valid.
5358 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5359 will fail since it requires the userinfo. Now, the userinfo
5360 is allocated as "" if actual userinfo does not exist. Actually,
5361 it must exist and it is totally Ok to drop client connections
5362 that does not announce the userinfo. However, we will make
5363 this workaround for now.
5365 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5366 to return the remote port by socket.
5368 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5370 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5371 SILC_SERVER_PENDING_EXEC and added an new macro
5372 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5373 data or when error occurs while processing the pending command.
5375 Added new argument `destructor' into silc_server_command_pending
5376 and to the SilcServerCommandPending object. This destructor is
5377 now called after calling the pending callback or if error occurs
5378 immediately. If error occurs the actual pending callback won't
5379 be called at all - only the destructor. The destructor may be
5380 NULL if destructor is not needed.
5382 All this applies for client library code as well. Similar
5383 changes were made there as well for the pending commands.
5385 In the client, the application must now allocate the
5386 SilcClientCommandContext with the silc_client_command_alloc
5389 * Added reference counter to the SilcServerCommandContext. Added
5390 function silc_server_command_alloc and silc_server_command_dup
5393 Same type of functions added to the client library for the same
5396 * Removed the cmd_ident from IDListData away since it is now
5397 global for all connections. It is the command identifier used
5398 in command sending and with pending commands. The affected file
5401 * Added reference counter to the SilcSocketConnection objecet to
5402 indicate the usage count of the object. The object won't be
5403 freed untill the reference counter hits zero. Currently only
5404 server uses this, and client ignores it. The client must be
5405 set to use this too later. The affected files are
5406 lib/silccore/silcsockconn.[ch]. Added also the function
5407 silc_socket_dup to increase the reference counter.
5409 This was mainly added because it is possible that the socket
5410 is removed underneath of pending command or other async
5411 operation. Now it won't be free'd and proper DISCONNECTING
5412 flags, etc. can be set to avoid sending data to connection that
5413 is not valid anymore.
5415 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5416 the connection. After that it sets SILC_SET_DISCONNECTED.
5417 It is, however, possible that the socket data is not still freed.
5418 The silc_server_packet_process now checks that data is not
5419 read or written to connection that is DISCONNECTED. The socket
5420 get's freed when the reference counter hits zero.
5422 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * Changed the client operation API: channel_message operation's
5425 `sender' is now the client entry of the sender, not the nickname
5426 and the `channel' is the channel entry, not the channel name.
5428 In the private_message operation the `sender' is now also the
5429 client entry of the sender not the nickname.
5431 Affected file is lib/silcclient/ops.h and all applications
5432 using the client operations.
5434 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5436 * Moved the calling of ops->connect() from connect_to_server_final
5437 into receive_new_id functin since that is the point when the
5438 client is actually allowed to send traffic to network. The
5439 affected file is lib/silcclient/client.c.
5441 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5443 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5444 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5445 (if needs broadcasting) instead of broadcasting the packets one
5446 by one which would make a burst in the network traffic.
5448 * Added `broadcast' argument to the functions in silcd/server.[ch]
5449 silc_server_create_new_channel[_with_id] to indicate whether
5450 to send New Channel packet to primary router.
5452 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5454 * Added new function into the silcd/server.[ch] files:
5455 silc_server_create_new_channel_with_id to create new channel with
5456 already existing Channel ID.
5458 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5459 lib/silccore/silcpacket.h. This packet is used t send list of
5460 Set Mode payloads inside one packet. Server uses this to set
5461 the modes for the channels and clients on those channels, that it
5462 announced to the router when it connected to it. The protocol
5463 specification has been updated accordingly.
5465 * The silc_server_new_channel did not handle the packet coming
5466 from normal server as it normally does not send that. However,
5467 when it announces its channels it does send it. Implemented
5468 the support for that.
5470 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5471 into the file lib/silccore/id.h.
5473 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5475 * Fixed memory leaks in the functions silc_idlist_del_client,
5476 silc_idlist_del_channel and silc_idlist_del_server in the file
5477 silcd/idlist.c. All of those leaked like a sieve.
5479 * Fixed some small memory leaks in the client's function
5480 silc_client_notify_by_server.
5482 * Added functions into silcd/server.c: silc_server_announce_clients,
5483 silc_server_announce_channels and silc_server_announce_server.
5484 These functions are used by normal and router server to announce
5485 to its primary router about clients, channels and servers (when
5486 router) that we own. This is done after we've connected to the
5489 These functions effectively implements the following packet types:
5490 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5491 and SILC_PACKET_NEW_ID_LIST.
5493 * Added new functions into the silcd/packet_receive.[ch]:
5494 silc_server_new_id_list, silc_server_new_channel_list and
5495 silc_server_new_channel_user_list to handle the incoming
5496 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5498 * Added support of changing Channel ID in the function
5499 silc_server_replace_id. If the server that announces a channel
5500 to the router already exists in the router (with same name but
5501 with different Channel ID), router is responsible to send
5502 Replace ID packet to the server and force the server to change
5503 the Channel ID to the one router has.
5505 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5506 client that the Channel ID has been changed by the router. The
5507 normal server sends this to the client. Client must start using
5508 the new Channel ID as the channel's ID.
5510 Implemented handling of this new type into lib/silcclient/client.c
5511 into the function silc_client_notify_by_server.
5513 * Added new function silc_idlist_replace_channel_id into the files
5514 silcd/idlist.[ch] to replace the Channel ID.
5516 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5518 * Call silc_server_command_identify_check always when processing
5519 the IDENTIFY command in silcd/command.c
5521 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5523 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5524 send keepalive packets. The packet can be sent by clients,
5525 servers and routers.
5527 Added function silc_socket_set_heartbeat into the file
5528 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5529 If not set, the heartbeat is not performed. The actual
5530 heartbeat is implemented in the low level socket connection
5531 library. However, application is responsible of actually
5534 Added silc_server_send_heartbeat to send the actual heartbeat
5535 packet into silcd/packet_send.[ch]. Server now performs
5536 keepalive with all connections.
5538 * Added silc_task_get_first function into lib/silcutil/silctask.c
5539 to return the timeout task with shortest timeout. There was a bug
5540 in task unregistration that caused problems. TODO has been
5541 updated to include that task system must be rewritten.
5543 * The client library will now resolve the client information when
5544 receiving JOIN notify from server for client that we know but
5545 have incomplete information.
5547 * Rewrote parts of silc_server_remove_from_channels and
5548 silc_server_remove_from_one_channel as they did not remove the
5549 channel in some circumstances even though they should've.
5551 * Encryption problem encountered in server:
5553 The LEAVE command used to send the Channel Key packet to the
5554 router immediately after generating it. However, the code
5555 had earlier sent Remove Channel user packet but not immediately,
5556 ie. it was put to queue. The order of packets in the router
5557 was that Channel Key packet was first and Remove Channel User
5558 packet was second, even though they were encrypted in the
5559 reverse order. For this reason, MAC check failed. Now, this
5560 is fixed by not sending the Channel Key packet immediately but
5561 putting it to queue. However, this is more fundamental problem:
5562 packets that are in queue should actually not be encrypted
5563 because packets that are sent immediately gets encrypted
5564 actually with wrong IV (and thus MAC check fails). So, packets
5565 that are in queue should be encrypted when they are sent to
5566 the wire and not when they put to the queue.
5568 However, the problem is that the current system has not been
5569 designed to work that way. Instead, the packet is encrypted
5570 as soon as possible and left to the queue. The queue is then
5571 just purged into wire. There won't be any fixes for this
5572 any time soon. So, the current semantic for packet sending
5575 o If you send packet to remote host and do not force the send
5576 (the packet will be in queue) then all subsequent packets to the
5577 same remote host must also be put to the queue. Only after the
5578 queue has been purged is it safe again to force the packet
5581 o If you send all packets immediately then it safe to send
5582 any of subsequent packets through the queue, however, after
5583 the first packet is put to queue then any subsequent packets
5584 must also be put to the queue.
5586 Follow these rules and everything works fine.
5588 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5590 * Added new function silc_server_remove_clients_by_server to
5591 remove all client entries from ID list when the server connection
5592 is lost. In this case it is also important to invalidate all
5593 client entires as they hold the invalid server entry. This
5594 fixes fatal bug when server has lost connection and will reconnect
5597 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5599 * Made some sanity checks to silc_server_daemonise like to check
5600 whether the requested user and group actually exists.
5602 * Added sanity check to SKE's silc_ske_responder_finish to check
5603 that the public and private key actually is valid.
5605 * Invalidate the client's nickname when receiving Replace ID
5606 packet and the Client ID is being replaced. This means that the
5607 server will query the nickname if someone needs it (client)
5610 * Sort the ID Cache in client library when the ID Cache data
5611 has changed (needs sorting).
5613 * Do not allow for SILC client to create several connections to
5614 several servers. The client does not support windows right now
5615 and generating multiple connections causes weird behaviour.
5617 Irssi-silc client does support windows and can handle several
5618 connections without problems, see: www.irssi.org and SILC plugin.
5620 * Fixed some places where client was added to the IDList. The
5621 rule of thumb is following (in order to get everything right):
5622 If the client is directly connected local client then the
5623 `connection' argument must be set and `router' argument must be
5624 NULL to silc_idlist_add_client function. If the client is not
5625 directly connected client then the `router' argument must
5626 bet set and the `connection' argument must be NULL to the
5627 silc_idlist_add_client function.
5629 * The funtion silc_server_packet_send_local_channel actually did
5630 not check whether the client was locally connected or not. It
5631 does that now. Fixed a bug related to LEAVE command.
5633 * Fixed Remove Channel User payload parsing bug in server's
5634 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5636 * The server's silc_server_save_channel_key now checks also the
5637 global ID list for the channel as it might not be in the local
5638 list. Fixed a bug related to LEAVE command.
5640 * Is this the end of the [<unknown>] buglet that has been lurking
5641 around for a long time? A little for loop fix in server's
5642 silc_server_command_whois_parse that is used by both IDENTIFY
5643 and WHOIS command. At least, this was a clear bug and a cause
5644 of one type of [<unknown>] buglet.
5646 * WHOIS and IDENTIFY commands call the function
5647 silc_server_command_[whois/identify]_check function even if
5648 we are not router server.
5650 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5652 * Added --with-gmp configuration option. If set the GMP
5653 is always compiled in the SILC source tree. If not set then
5654 it is checked whether the system has the GMP3 installed. If
5655 it has then the GMP won't be compiled (the system's headers
5656 and library is used), if it doesn't have it then the GMP is
5657 compiled in the SILC source tree.
5659 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5661 * Changed RSA private exponent generation to what PKCS #1
5662 suggests. We try to find the smallest possible d by doing
5663 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5664 not security fix but optimization.
5666 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5668 * Added new config entry [Identity] to fork the server and run
5669 it as specific user and group. A patch from Bostik.
5671 * Imported Dotconf configuration library into lib/dotconf.
5672 This will be used to create the SILC configuration files later.
5673 It will appear in the distsribution after this commit.
5675 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5677 * A big code auditing weekend happening. Auditing code for
5678 obvious mistakes, bugs and errors. Also, removing any code
5681 Removed files for being obsolete:
5683 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5684 inline in the file lib/silcutil/silcbuffer.h)
5686 o lib/silcutil/silcbufutil.c (the header has inline versions)
5688 Changed code to fix possible error conditions:
5690 o The buffer formatting routines now check that the destination
5691 buffer really has enough space to add the data. This applies for
5692 both buffer formatting and unformatting
5693 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5694 unformatting was changed to accomodate following rules:
5695 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5696 sent to the function while XXX_*STRING will not allocate or copy
5697 the data into the buffer. Instead it sets the pointer from the
5698 buffer into the pointer sent as argument (XXX_*STRING used to
5699 require that the pointer must be allocated already). This change
5700 makes this whole thing a bit more consistent and more optimized
5701 (note that the data returned in the unformatting with XXX_*STRING
5702 must not be freed now). The routines return now -1 on error.
5704 o Tried to find all code that use buffer_format and buffer_unformat
5705 and added return value checking to prevent formatting and
5706 especially unformatting errors and possible subsequent fatal
5709 o Changed ske->x and ske->KEY to mallocated pointers in
5710 lib/silcske/silcske.h. Fixed possible data and memory leak.
5712 o Added return value checking to all *_parse* functions. Fixed
5713 many memory leaks as well.
5715 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5716 so that buffer overflows would not happen. All code now also
5717 checks the return value as it can fail.
5719 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5721 * Added reconnection support to server if the normal server looses
5722 its connection to the router (for example if router is rebooted).
5723 The server performs normal reconnection strategy implemented
5724 to the server. Affected file silcd/server.c.
5726 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5728 * Added new packet type SILC_PACKET_SET_MODE that is used to
5729 distribute the information about changed modes (for clients,
5730 channels and clients channel modes) to all routers in the
5731 network. Updated the protocol specification accordingly.
5733 Added functions into silcd/packet_send.c and
5734 silcd/packet_receive.c: silc_server_send_set_mode,
5735 silc_server_set_mode.
5737 Added new files silcmode.[ch] into lib/silccore that implements
5738 the encoding and decoding of Set Mode Payload. Added new type
5739 SilcSetModePayload. Moved the definitions of different modes
5740 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5742 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5744 * Oops, a little mistake in server's connection authentication
5745 protocol. The protocol is not ended with FAILURE but with
5746 SUCCESS if the authentication is Ok. :) Affected file is
5749 * Implemented NICK_CHANGE notify handling in server in the file
5750 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5751 the local clients on the channel. After the changing nickname
5752 in router environment snhould work and the [<unknown>] nickname
5753 should appear no more.
5755 The silc_server_replace_id function that receives the Replace ID
5756 payload now sends the NICK_CHANGE notify type also in the file
5757 silcd/packet_receive.c
5759 * Changed WHOIS and IDENTIFY command to support the maximum amount
5760 of arguments defined in protocol specs (3328 arguments). This
5761 fixed a bug that caused problems when there were more than three
5764 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5766 * Added extra parameter, command identifier, to the
5767 silc_client_send_command so that explicit command identifier
5770 Changed that ID list routines uses specific command identifier
5771 when sending WHOIS/IDENTIFY requests to the server so that they
5772 can be identified when the reply comes back.
5774 Affected files lib/silcclient/command.[ch],
5775 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5777 * Added `sender' argument to silc_server_packet_send_to_channel
5778 to indicaet the sender who originally sent the packet to us
5779 that we are now re-sending. Ignored if NULL. Affected file
5780 silcd/packet_send.[ch].
5782 * Added some server statistics support in silcd/server_internal.h
5783 SilcServerStatistics structure and around the server code. Also
5784 send some nice statistics information when client is connecting
5787 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5789 * Fixed channel ID decoding in server's JOIN command reply in
5790 silcd/command_reply.c
5792 * Fixed braodcasting of replace ID payload to not to send it if
5793 we are standalone server in silcd/packet_receive.c.
5795 * Fixed all channel message sending routines to not to send
5796 packets to clients that has router set, since they are routed
5797 separately in the same function earlier. Affects file
5798 silcd/packet_send.c and all channel packet sending functions.
5800 * In USERS reply, res_argv[i] are not allocated, the table
5801 is allocated. Thus changed that free the table, not its
5804 * In server's whois_check and identify_check if the client is
5805 locally connected do not send any WHOIS commands - they are not
5808 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5810 * Fixed some minor bugs in client when sending WHOIS command. The
5811 arguments was in wrong order.
5813 * Removed statis function add_to_channel from server in
5814 silcd/command.c that was previously used with the joining but
5817 * Tested USERS command in router environment successfully with two
5818 routers, two servers and two clients.
5820 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5822 * Reorganized the USERS command and command reply in client library
5823 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5824 When the command is given by user we register a pending command
5825 callback that will reprocess the command after the reply has been
5826 received from the server. When reprocessing the packet we then
5827 display the information. Thus, the USERS information is displayed
5828 now in the command callback instead of in the command reply
5829 callback. The processing of the command is same as previously
5830 when server has sent the command reply in the JOINing process.
5832 * Added to USERS command in silcd/command_reply.c to join the client,
5833 we didn't use to know about, to the channel after we've created
5834 a client entry for it. Also, for clienet we did know already still
5835 check whether it is on the channel or not and add it if not.
5837 * Removed silc_server_command_join_notify as the function and its
5840 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5842 * Changed the client's pending command handling to the same as the
5843 server's pending command handling. It is also now possible to
5844 execute command reply functions from other command reply
5845 function as the function callbacks for commands and command
5846 replies are one and same. The pending commands are not static
5847 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5848 in client connection context. Thus, pending commands are server
5849 connection specific as it is convenient.
5851 Changed the function silc_client_command_pending and
5852 silc_client_command_pending_del and added new function
5853 silc_client_command_pending_check. Removed the
5854 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5857 * Added cmd_ident, current command identifier, to the client
5858 connection context in lib/silcclient/client.h to keep track on
5859 command identifiers used in command sending. Client's command reply
5860 function handling now supports the mandatory command identifiers.
5862 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5863 funtions in client to fully support pending command callbacks.
5865 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5866 as one of the arguments to the application in the command reply
5869 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5870 before first releasing SILC but came back. Now it is removed again
5871 and should come back nomore. The FORWARDED flag was used only
5872 by the JOINing procedure by forwarding the command packet to router.
5873 Now, the JOINing procedure has been changed to more generic (due
5874 to various router environment issues) and FORWARDED is not needed
5875 anymore for anything. The protocol specification is yet to be
5878 Now, removed silc_server_packet_forward from server and the flag
5879 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5881 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5883 * Renamed NAMES command to USERS command. The NAMES was named that
5884 due to historical reasons. Now it is renamed. Also, rewrote
5885 parts of the USERS command. The nickname list is not sent anymore
5886 by the server. Only Client ID and mode lists are sent in the USERS
5887 command. Changed this also to the protocol specification.
5889 The client now resolves the names and stuff after it receives
5890 the USERS list from the server when joining to the channel.
5892 * WHOIS and IDENTIFY commands has been changed to support multiple
5893 Client ID's per command. One can now search for multiple users
5894 in the network by sending only one WHOIS or IDENTIFY command.
5895 Changed the code and the protocol specifications.
5897 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5898 uses silc_server_command_whois_parse to parse the request. */
5900 * If normal server, do not parse the WHOIS and IDENTIFY requests
5901 before sending it to the router. Saves some time.
5903 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5905 * Fixed JOIN command on client library. Wrong number of arguments
5906 used to crash the client.
5908 * Added silc_server_channel_has_global function to check whether
5909 channel has global users or not.
5911 * Added silc_server_channel_has_local function to check whether channel
5912 has locally connected clients on the channel.
5914 * The silc_server_remove_from_one_channel now checks whether the
5915 channel has global users or not after given client was removed from
5916 the channel. It also checks whether the channel has local clients
5917 on the channel anymore. If it does not have then the channel entry
5918 is removed as it is not needed anymore.
5920 * The silc_server_notify now checks on JOIN notify whether the joining
5921 client is one of locally connected or global. If it is global then
5922 the channel has now global users on the channel and that is marked
5923 to the channel entry. Also, it now saves the global client to
5924 global list who is joining and JOINs it to the channel. This is
5925 for normal server, that is.
5927 Changed silc_server_send_notify_on_channel,
5928 silc_server_packet_relay_to_channel and
5929 silc_server_packet_send_to_channel check if we are normal server
5930 and client has router set (ie. global client) do not send the
5931 message to that client, as it is already routed to our router.
5933 * Implemented LEAVE notify type handling in silc_server_notify
5936 * Tested LEAVE command in router environment successfully. Tested
5937 with two routers, two servers and two clients.
5941 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5943 * Implemented SIGNOFF notify type handling in silc_server_notify
5946 * silc_server_remove_id now removes the client entry from all channels
5947 it has joined and thusly sends SIGNOFF notify type.
5949 * Rewrote the NAMES list generation in server by removing two excess
5950 loops. The lists are created now inside one loop.
5952 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5954 * silc_server_remove_channel_user checks now also global list
5955 for channel and client.
5957 * silc_server_new_channel_user checks now both local and global
5958 list for channel and client. Fixed a bug in client id decoding.
5959 Used to decode wrong buffer.
5961 * silc_server_channel_message checks now both local and global
5962 list for channel entry.
5964 * Tested channel joining (hence JOIN) in router environment
5965 successfully. Tested with two routers, two servers and two
5968 * Tested channel message sending in router environment successfully.
5970 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5972 * Added silc_server_save_channel_key into server.[ch] to save the
5973 received channel key in Channel Key payload processing. It is
5974 also used in JOIN command reply handling.
5976 Equivalent function silc_client_save_channel_key added into
5977 client.[ch] into client library.
5979 * Changed JOIN command reply to send information whether the channel
5980 was created or not (is existing already) and the channel key
5981 payload. Changed protocol specs accordingly.
5983 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5984 the request was sent by ID and not by nickname. Crashed on
5987 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5989 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5990 now correctly save the received data.
5992 * silc_server_free_sock_user_data now notifies routers in the
5993 network about entities leaving the network.
5995 At the same time implemented functions silc_server_remove_id
5996 and silc_server_send_remove_id to receive and send REMOVE_ID
5997 packets. The packet is used to notify routers in the network
5998 about leaving entities. The ID removed will become invalid in
6001 * Added function silc_idlist_del_server into server. Removes and
6002 free's server entry from ID list.
6004 * silc_server_private_message function now checks, if we are router,
6005 that the destination ID really is valid ID, naturally.
6007 * In router when NEW_ID packet is received (for new client) the
6008 hash of the Client ID is saved in the ID Cache but the
6009 client->nickname is set to NULL, instead of putting the hash
6012 IDENTIFY command now also checks that client->nickname must be
6013 valid. If it is not if will request the data from the server who
6014 owns the client. Added new function
6015 silc_server_command_identify_check.
6017 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6018 to set the command to already allocated Command Payload.
6020 * Tested private message sending in router environment with two
6021 routers, two servers and two clients. Fixed minor bugs and now
6024 * Fixed segfault from client's NAMES command. Used to crash if
6027 * Forwarded packets must not be routed even if it is not destined
6028 to the receiver. Changed server code comply with this.
6030 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6032 * Added `require_reverse_mapping' boolean value to ServerParams
6033 structure. If TRUE (not default) the server will require that
6034 the connecting host has fully qualified domain name.
6036 If the reverse mapping is not required and hostname could not be
6037 found the IP address is used as hostname.
6039 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6041 * Implemented version string checking to both client and server.
6042 The check is incomplete currently due to the abnormal version
6043 strings used in development version of SILC.
6045 * Changed all command functions in server to use the new
6048 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6050 * Changed char *data to unsigned char *data in ID Cache system to
6051 support binary data as ID Cache data. Changed code to support
6052 binary data in lib/silccore/idcache.c.
6054 * Renamed silc_server_packet_relay_command_reply to
6055 silc_server_command_reply as it is normal packet receiving
6056 function. Rewrote the function to accept command replys for
6057 servers and not only for clients.
6059 * Mark remote router always as registered server if we are connecting
6060 to it. Otherwise, commands sent by the router to us are ignored.
6062 * All ID List find routines now returns the ID Cache Entry pointer
6063 as well if requested.
6065 * WHOIS command works now in router environment, tested with two
6066 routers, two servers and two clients.
6068 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6069 in router environment (as it is almost equivalent to WHOIS) but
6070 hasn't been tested thoroughly. Added new functions:
6072 silc_server_command_identify_parse
6073 silc_server_command_identify_send_reply
6074 silc_server_command_identify_from_client
6075 silc_server_command_identify_from_server
6077 * Disabled route cache adding because adding two different ID's with
6078 same IP replaces the old cache entry thus giving wrong route.
6079 The entry->router->connection is always the fastest route anyway
6080 so route cache may not be needed. Of course, new routes maybe
6081 established after receiving the ID when the entry->router->connection
6082 might not be anymore the most optimal.
6084 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6086 * Add route cache for received ID for fast routing.
6088 * Added silc_server_packet_route to route received packet on router
6089 that is not destined to us.
6091 * Renamed silc_server_get_route to silc_server_route_get.
6093 * Added id_string and id_string_len fields into SilcServer to
6094 include encoded ServerID for fast comparing without excess
6095 encoding of the ID's.
6097 * Cleaned up WHOIS command on server side. Added following static
6100 silc_server_command_whois_parse
6101 silc_server_command_whois_check
6102 silc_server_command_whois_send_reply
6103 silc_server_command_whois_from_client
6104 silc_server_command_whois_from_server
6106 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6107 arguments in command replies. All command functions should be
6108 updated to use this macro.
6110 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6112 * Minor typo fixes on command reply handling on server.
6114 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6116 * Added silc_server_command_add_to_channel internal routine to add
6117 the client to the channel after router has created the channel and
6118 sent command reply to the server.
6120 * Added generic silc_server_send_command to send any command from
6123 * Use static buffer with ID rendering instead of duplicating data.
6125 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6127 * Fixed a channel user mode bug when joining to a channel server gave
6128 everybody channel founder rights, oops.
6130 * We mark ourselves as the router of the incoming server connection
6131 if we are router ourselves. This way we can check in some packet
6132 sending functions whether it is locally connected server. For
6133 incoming router connections we put NULL.
6135 * For router sending packets locally means now always sending the
6136 packet cell wide; to local clients and local servers. For normal
6137 server sending packet locally means sending it to only local
6140 * Fixed the JOIN command to really work in router environment. If the
6141 channel is created it is always created by the router. Router is
6142 also responsible of making the initial joining to the channel,
6143 sending JOIN notify to the sending server and distributing
6144 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6145 does not exist server doesn't do anything else but forward the
6146 command to the router which performs everything.
6148 * Added silc_server_send_channel_key function to send the Channel Key
6151 * Added silc_server_create_channel_key to create new channel key. The
6152 channel key is now re-generated everytime someone joins or leaves
6153 a channel, as protocol dictates. Note: channel->key_len is the
6156 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6158 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6159 packet_receive.[ch] to separate packet sending and receiving
6160 routines. The server.[ch] now includes everything else including
6161 actual packet processing (writing and reading data) and other
6164 Renamed silc_server_private_message_send_internal to
6165 silc_server_send_private_message. The routine is still though
6166 used only to relay private messages as server does not send
6167 private messages itself.
6169 Renamed silc_server_new_channel to silc_server_create_new_channel
6170 and added new function sicl_server_new_channel that handles the
6171 incoming New Channel packet. Added also new sending function
6172 silc_server_send_new_channel to send New Channel Payload.
6174 * Added new function silc_server_notify to process incoming notify
6175 packet to the server/router. Server may then relay the notify
6176 to clients if needed.
6178 * Added new function silc_server_new_channel_user to process incoming
6179 New Channel User packet. Router will redistribute the packet and
6180 send JOIN notify to its local clients and locally connected servers
6181 if needed. Normal server will send JOIN notify to its local client
6182 on same channel when received this packet. Added also corresponding
6183 sending function silc_server_send_new_channel_user to sent the
6186 * Added boolean route argument to send_notif_to_channel and
6187 packet_send_to_channel functions to attempt to route the packet
6188 if it is TRUE and send only locally if it is FALSE.
6190 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6192 * silc_server_replace_id now broadcasts the received replace ID
6193 packet if it is not broadcast packet already. The router must
6194 broadcast to inform other routers about changed ID.
6196 * Added backpointer to server's router into SilcServer context in
6197 silcd/server_internal.h.
6199 * Fixed silc_server_packet_broadcast to send correct broadcast
6202 * The channel key is now distributed to the local client as soon
6203 as it is received from the router (in router environment) so that
6204 no other packet may be sent for the channel until client has
6207 * silc_server_remove_channel_user now broadcasts the received
6208 Remove Channel User packet if it is not broadcast packet already.
6209 The router must broadcast to inform other routers about removed
6212 * Added users field into SilcPacketContext that is a reference count
6213 of the context. One can increase the reference count by calling
6214 silc_packet_context_dup which is now changed to just increase the
6215 reference count instead of duplicating the data. The reference
6216 count is decresed by calling silc_packet_context_free that will
6217 free the data after the reference count hits zero.
6219 For now on the packet context and everything allocated into it
6220 (including the raw packet from network) must be freed by calling
6221 the new silc_packet_context_free function. Added also new function
6222 silc_packet_context_alloc that must be used now to allocate the
6223 context. This also means that if a routine is asynchronous from
6224 silc_[client/server]_packet_parse_type the packet context must
6225 be duplicated by calling silc_packet_context_dup. Otherwise it
6226 gets free'd after silc_[client/server]_packet_parse_type returns.
6227 Also, one must remember that if packet is duplicated then its
6228 reference count must be decresed by calling the free function as
6229 many times as it was duplicated.
6231 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6232 from both client and server.
6234 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6236 * Made joining to a channel working in router environment.
6238 * Cleaned up JOIN command on server side and create function
6239 silc_server_command_join_channel internal routine to make the
6242 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6244 * Changed silc_command_pending list to SilcDList. Also, added
6245 `ident' field to SilcServerCommandPending structure to identify
6246 the reply and to call correct callback.
6248 Added silc_server_command_pending_check function to replace the
6249 corresnponding macro. The silc_command_pending list is not
6252 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6253 to set identifier to previously allocated Command Payload. It
6254 is used to set identifier for command when resending Command
6257 * Added silc_command_payload_encode_payload to encode Command
6258 Payload buffer from SilcCommandPayload structure.
6260 * Added silc_argument_payload_encode_payload to encode Argument
6261 payload buffer from SilcArgumentPayload structure.
6263 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6265 * Changed WHOIS command to support router connection on server side.
6266 The whois request is always sent to router unless the server is
6267 standalone server. After server has received the reply from the
6268 router will it send the reply to the client.
6270 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6271 broadcast received broadcast packet. The function is used only
6272 by router. The broadcast packet is always sent to the router's
6275 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6276 render given ID to printable string, for log files for example.
6278 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6280 * Made basic router to router connections working. At least they
6281 can now connect to each other but nothing really works the way
6282 they are supposed - yet.
6284 * Added new initiator token to RouterConnection configuration
6285 file in silcd/serverconfig.[ch]. It is used to tell whether we
6286 are the initiator to the remote router or whether we'll expect
6287 the other end to connect.
6289 * Moved registering of listener task to silc_server_init, hence
6290 the server starts listenning as soon as it is run, even if it
6291 does not have connections to other routers. Let's see how well
6294 * Changed default connection retry timeouts for more suitable in
6297 * Removed cipher and such arguments from silc_idlist_add_client
6298 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6299 Added new function silc_idlist_add_data to add the keys and stuff
6302 * Added SilcIDListData structure and added it to SilcClientEntry
6303 and SilcServerEntry as their first field in the structure. This
6304 way we can explicitly cast the ID entries to the SilcIDListData
6305 structure and get common data for the entries. In past, we had
6306 to first check what type of connection it is and then cast it to
6307 correct ID entry type. Now, we can directly cast the opaque
6308 pointer to the SilcIDListData (no matter what ID entry it actually
6309 is) and get the data needed.
6311 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6313 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6314 in some circumstances even if threre were timeout tasks, though not
6315 IO tasks, but tasks anyway. Now fixed.
6317 * Defined SilcServerConnection structure to hold connection specific
6318 stuff about directly connected servers and routers. The definition
6319 is currently in silcd/server_internal.h. I thought about having
6320 a bit more important role fro this struct but for now it is used
6321 only when connecting to other server (or router actually).
6323 * Added connecting retry support in server when connecting to
6324 router(s). The retry feature implement exponential backoff
6325 algorithm. Also, added SilcServerParams structure to hold default
6326 parameters for server. For now, it include these retry settings
6327 and are hard coded. After server is moded to be as Silc Server
6328 Library this structure will be more important.
6330 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6332 * Changed client librarys channel->clients table to SilcList and
6333 changed code accordingly.
6335 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6337 * Changed client's channel table to SilcList and changed code
6338 accordingly. Also changed SilcChannelClientEntry to include back-
6339 pointer to the channel so that client entry can use that structure
6340 as list as well and we have fast cross-reference to the channel.
6341 This change dramatically decreased the complexity of channel
6342 handling with client entry and vice versa (removed one extra
6343 loop when searching for channel entry from many functions).
6345 * Changed server->sim from table to SilcDList and changed code
6348 * NAMES command can now be used from user interface. It will show
6349 the user list on the channel, neatly.
6351 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6352 Code now saves realname of the user if it becomes available.
6354 * Renamed configure.in to configure.in.pre and made ./prepare
6355 script to automatically add correct version string to
6356 configure.in which it creates from configure.in.pre.
6358 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6360 * NAMES command reply now shows users mode with the nickname when
6363 * Moved silc_client_ch[u]mode[_char] functions from
6364 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6365 place sucks, they are utility functions and should be in some
6368 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6370 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6373 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6377 * Added TRQ (efficient deque and list library) into lib/trq. This is
6378 a very good list library that is currently used in the SILC. Defined
6379 SilcList API over the library because I didn't like the API very
6380 much. See lib/trq/silclist.h for the API and examples of how to
6381 use the API. Fixed various places in the code to use the new
6382 SilcList API. The SilcList is meant for lists that has a structure
6383 already defined as a list. It is not suitable to add just some
6384 context to the list (in TRQ, the context is the list actually).
6386 So, I defined SilcDList that can be used for the purpose where
6387 predefined list structure does not exit. This can be used as
6388 such list. Now some context just can be added to the SilcDList.
6389 Currently this list is not used in the SILC just yet, though there
6390 are a lot places where this can replace dynamically allocated
6391 tables and I will fix these places, later, to use SilcDList.
6392 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6393 and use TRQ internally).
6395 Also fixed some annoying warning messages that the original TRQ
6396 code generated. Also minor changes to TRQ's Makefile.in.
6398 * Added support for querying by Client ID to both WHOIS and
6399 IDENTIFY commands into server, as required by the protocol.
6401 * Removed method function pointers from SilcBuffer structure. They
6402 weren't used to anything and just increased the context size for
6403 no good reason. This change also made silc_buffer_alloc and
6404 silc_buffer_free functions inline functions.
6406 * Disabled command flooding detection support until it's fixed so
6407 that it accepts commands in but does not execute them more than once
6410 * Added silc_net_localhost(), to return local hostname, into
6411 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6412 that must be initialized before calling silc_client_init.
6414 * Added new function: silc_server_send_notify_on_channels to send
6415 notify messages to all channels client has joined. It is assured
6416 that the message is sent only once per client.
6418 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6419 lib/silcutil/silcutil.[ch] as silc_format function. The new
6420 function is generic and is used by server as well, not only by
6421 the logging routines.
6423 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6424 the provided version string was not acceptable. Added new function:
6425 silc_ske_check_version into lib/silcske/silcske.h. The function
6426 must be implemented by the application (client or server) and it
6427 does not reside in the SKE library. The function checks the version
6428 string remote end sent.
6430 * Added back pointers (to opaque context and to SilcSocketConnection)
6431 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6433 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6434 duplicate packet context structure.
6436 * Changed `notify' client operation to send same arguments as client
6437 receives from server except for ID's. ID's are mapped to correct
6438 ID entry and that is returned. Also, if channel entry is not sent
6439 by server but the notify is for channel the channel entry is sent
6440 to application (otherwise application doesn't know that it is for
6441 channel (library gets it from packet's Destination ID)).
6443 * Added silc_client_remove_from_channels into client library to
6444 remove a client from all channels it has joined to. Used when
6445 received SIGNOFF notify from server. Added also new function
6446 silc_client_replace_from_channels to replace old ID entry with
6447 new ID entry on all channels. Used when received NICK_CHANGE
6450 * Fixed ID Cache list handling in silc_idlist_get_client in
6451 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6452 to get (or query) client by ID.
6454 * Updated TODO list.
6456 * Added connection authentication status message defined by the
6457 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6458 support for these into the code in client and server side.
6460 * Added generic function silc_client_send_command to send any command
6461 with variable argument list. Application should use this function
6462 to send commands if the command functions provided by the library
6463 does not suite for the application's user interface needs.
6465 * Added new `failure' client operation. Application is notified about
6466 received failure packet if client is executing a protocol. In this
6467 case the protocol's execution has failed.
6469 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6470 is required by the protocol.
6472 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6473 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6476 * Added status flag to SilcSKE object to indicate realtime status
6477 of the SKE protocol.
6479 * Application receives now exactly same command reply arguments as
6480 the library receives from server. However, if ID is received the
6481 corresponding ID entry is returned to the application (eg. Client
6482 ID is mapped to correct SilcClientEntry entry and that is returned).
6483 Changed command_reply client operation due to this change.
6485 * Changed all ID's in commands and in command replys as ID Payloads.
6486 Change affected both client and server side codes.
6488 All ID's sent in SILC network (with execption of ID's in SILC
6489 Packet header) are sent in ID Payload to support variable length
6492 * Server now notifies nick changes and notifies all clients on
6493 the channels about the new nickname (about the new Client ID,
6496 * Implemented CMODE command to change channel modes. Supports all
6497 channel modes defined by the protocol specs except ban and invite
6498 lists. (Also, private channel key mode is supported but support for
6499 setting private channel key in client is missing, thus, this mode
6500 has no effect on client side (except that server requires that the
6501 client uses private channel key and normal channel traffic does not
6504 Also, invite mode works per se, but INVITE command does not work
6505 yet correctly, so you can set channel as invite only channel but
6506 inviting clients to the channel does not work (it is yet to be
6507 thought what's the best way to do it).
6509 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6510 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6511 Implemented CUMODE command to change user's mode on the channel.
6512 Supports all modes defined by the protocol specs.
6514 * Added NAMES command reply to return users modes on the channel.
6516 * Removed unnecessary and slow ciphers from lib/silccrypt.
6518 * Set SO_KEEPALIVE option to connection sockets by default.
6520 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6522 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6523 redefined the Notify Payload into protocol specs.
6525 * Added silc_id_payload_parse_id to get ID directly from raw
6528 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6530 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6531 accept searching by Client ID as well.
6533 * Added support for LEAVE and SIGNOFF notify types in client library.
6535 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6536 to parse ID Payload from raw data.
6538 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6540 * Added flags parameter into silc_ske_assemble_security_properties
6541 function in lib/silcske/silcske.[ch].
6543 * Changed notify client operation to fit better for notify messages
6544 sent by server. The notify payload received from server is now
6545 passed to the application (after parsing it to SilcNotifyPayload).
6546 It is application's responsibility to retrieve the arguments
6547 from the payload and show the message the way it wants. The message
6548 sent by server is implementation specific.
6550 * Changed public keys to comply with the protocol specification.
6551 Old public keys are not supported anymore and are not compatible.
6553 * Removed nickname from Channel Payload as the latest draft removed
6554 it. The client must resolve the nickname from the NAMES command
6555 reply received when it joined the channel.
6557 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6559 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6561 * Fixed some errors in protocol specification drafts.
6563 * Created lib/silccore/silcnotify.c to implement Notify Payload
6564 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6565 generic payloads described by protocol specifications. The file
6566 includes implementations for ID Payload and Argument Payload.
6568 * Changed Command Payload implementation to use the new Argument
6569 Payload. Changed command_xxxx_payload to command_payload_xxxx
6570 to comply with SILC coding conventions.
6572 * Added suppport for Argument Payload handling in Notify Payload
6573 implementation as protocol requires it. Added the new support
6574 into server and client lib as well.
6576 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6578 * Added support for multiple nicknames on same channel. [n] is
6579 added locally to the nickname if there are more than one same
6580 nicknames on the channel.
6582 * Server now sends all nicknames that matched WHOIS request.
6583 Client also shows the list received from server.
6585 * Added TOPIC command to client side. User can now set and show
6586 current topic on channel.
6588 * Added MOTD command to client and server. Also, server sends the
6589 motd when client connects to the server.
6591 * Changed version strings to comply ISO 8601.
6593 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6595 * Fixed protocol error handling in client library. It should now
6596 cope even if the SKE fails for some reason.
6598 * Made new protocol specification drafts for submitting to IETF.
6600 * Implemented TOPIC command to server in silcd/command.c.
6602 * Added two new notify types into lib/silccore/silcnotify.h:
6603 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6604 notify nickname change and topic setting/change on a channel.
6606 * API change of command_reply operation in client library. The
6607 application gets now the status type received from server as well.
6609 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6611 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6613 * Cras fixed and optimized the packet handling even further and
6614 it should work now. Minor change to the prototype of function
6615 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6617 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6619 * Added new function into lib/silcutil/silcschedule.[ch]:
6620 silc_schedule_with_fd to select() a specified fd. The function
6621 returns after timeout expires or data arrives or goes. The
6622 function is used by packet routines to wait that all data is
6623 received from network.
6625 * Fixed data reading from network in lib/silccore/silcpacket.c.
6626 The code now assures that all data is read from the fd and then
6627 continues packet processing. This was a bug fix since the code
6628 used to drop some data in some circumstances.
6630 * Added new function into lib/silcclient/client.[ch]:
6631 silc_client_start_key_exchange to start key exchange after
6632 connection has been established to server. The code internally
6633 now uses this funtion but its main purpose was to provide it
6634 for applications that perform their own connecting. After
6635 application has created a connection it merely calls this
6636 function to start the key exchange between client and server.
6637 The library takes care of everything else after that.
6639 Updated also lib/silcclient/README to explain the usage of
6642 * Do not send to application information that connection has
6643 been established. Application gets notified it by connect
6646 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6648 * Applied cras's patch to add silc_schedule_one function. The
6649 function runs scheduler once and returns.
6651 * Fixed the scheduler after cras messed it up. The timeout
6652 handling works now as it's supposed to work.
6654 * Added into lib/silccore/ silcnotify.h to include notify
6655 message types support. Changed silc_server_send_notify*
6656 functions, in server.[ch], to support those new notify types.
6657 Added the support for the notify types into client library,
6658 as well. Added new notify client operation into ops.h in
6661 * Changed silc_server_packet_send_to_channel to send normal
6662 packets instead of just channel message packets. The function
6663 is now used to send the notify packets to channels. It is not
6664 used to send channel message packets anymore, as server never
6667 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6668 va_arg()s as it seems to require it nowadays. I guess, if SILC
6669 is compiled with older va_arg() the new code should work anyway.
6671 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6673 * Splitted core library. Core library (lib/silccore) includes
6674 now only SILC protocol specific core (and common) components.
6675 Created new utility library (lib/silcutil) that includes more
6676 generic purpose stuff. The stuff for util library was taken
6677 from the old core library. This was minor and easy split.
6679 * Created SILC Client Library (lib/silcclient) that includes
6680 implementation of the SILC client without user interface. This
6681 was major move from silc/ directory. The code has been changed
6682 so that it is transparent towards the user interface. The
6683 silc/ directory includes now the same user interface as before
6684 and it uses the new client library. Read lib/silcclient/README.
6685 Basicly, the client library performs everything else related
6686 to SILC except user interface handling. Also, configuration
6687 files are considered to be part of user interface and library
6688 does not handle them.
6690 This change also changed a lot of structures, function naming etc.
6691 Most important change was that SilcClientWindow object was
6692 renamed to SilcClientConnection in the client library. Created
6693 also new file lib/silcclient/ops.h. Also added new files
6694 silc/local_command.[ch] and silc/client_ops.[ch].
6696 All these changes were made to make it easier for user interface
6697 designers to create what ever user interface for the SILC client
6700 It is also expected that the server will be moved to lib
6701 directory as well and SILC Server Library will be created;
6702 sometimes in the future.
6704 * Removed Local commands from lib/silccore/silccommand.h as
6705 they are application specific and new client library does not
6706 handle any of those anymore.
6708 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6709 old client implementation in silc/.
6711 * Added support for callback functions in SILC_LOG_* macros.
6712 Application can now set its own callbacks that will be called
6713 instead of using the default functions that will always print
6714 the debug messages to stderr (or stdout). Also, debugging can
6715 now be disabled by setting silc_debug to FALSE and re-enabled by
6716 setting it to TRUE. Note, that logging will still work even
6717 if debugging is disabled.
6719 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6720 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6721 silc_log_reset_debug_callbacks.
6723 * To enable debugging in silc client one must give now -d
6724 option on command line.
6726 * Changed silc_schedule_init to automatically allocate task queues
6727 if they are not allocated before calling it.
6729 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6731 * Added GMP 3.1 into math library.
6733 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6735 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6736 a channel in SILC network. The packet is used by servers and
6737 routers to notify other routers that user has left a channel.
6738 This little feature was missing until now. Added the feature
6739 to protocol specification as well.
6741 Added functions: silc_server_send_remove_channel_user and
6742 silc_server_remove_channel_user into server.[ch].
6744 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6745 lib/silccore/silcpacket.h. However, they are not implemented
6748 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6750 * Fixed joining to a channel and sending channel messages
6751 between server and router. The channel message sending should
6752 now work inside a cell.
6754 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6756 * Fixed the private message sending between server and router.
6757 The private message sending should now work inside a cell.
6759 * Added silc_server_replace_id into server.[ch] to replace
6760 existing ID in the SILC network.
6762 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6763 and silc_idlist_replace_server_id into idlist.[ch] in server.
6765 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6767 * Fixed the server to server connections. Server can again now
6768 connect to router. Router to router connections probably does
6771 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6773 * Added dynamic protocol registering support. Now protocols can
6774 registered and unregistered on the fly. Patch by cras.
6776 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6778 * Added lib/contrib directory to hold routines that some platforms
6779 don't have but are needed by SILC.
6781 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6782 into lin/contrib to provide getopt() and getopt_long() for
6783 those who don't have it.
6785 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6787 * Added AWAY command to client. When away message is set and
6788 client receives a private message packet the client automatically
6789 replies to the sender with the away message.
6791 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6792 bug seemed to be the cause of recent problems when compiling
6795 * Added version detection support to SKE protocol specification
6796 and added the new changes to the SKE implementation as well.
6797 There were other minor changes in the SKE protocol as well.
6799 Many changes in lib/silcske/silcske.[ch] and in
6800 lib/silcske/payload.[ch].
6802 * Added ^U functionality, clear input line. Patch from cras.
6804 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6806 * Mainly small bugfixes on core library. Fixed some debugging
6807 logging and buffer overflow in silclog.c.
6809 * Updated config.sub and config.guess on the distribution tree.
6811 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6813 * Added command lagging support in server. Client may execute
6814 commands now only once in two seconds.
6816 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6818 * Optimized packet reception. MAC computation and checking is now
6819 also more optimized. A lot previously duplicated code is now
6820 used as generic by both client and server.
6822 * Fixed key pair generation in clientutil.c
6824 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6826 * Added into lib/silccore/silcbufutil.[ch] new function;
6827 silc_buffer_realloc.
6829 * Moved generic packet sending/encryption functions to
6830 lib/silccore/silcpacket.[ch] from client and server. Some
6831 rewriting of the functions.
6833 * Moved all generic packet reception/decryption functions to
6834 lib/silccore/silcpacket.[ch] from client and server. The
6835 packet processing is now much cleaner in both client and server.
6836 These were major changes in both client and server.
6838 * Created many common functions in server to do packet sending.
6839 Previously code were duplicated a lot, this has been removed
6842 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6844 * Rewrote major parts of the ID cache system. Don't know
6845 whether it is better now or not but at least the API is more
6848 * Major rewrite on ID cache stuff on client because of the ID
6849 cache API changes. Added idlist.c to client.
6851 * Also major rewrite on ID cache stuff on server as well.
6852 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6853 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6854 in hand, instead they are all put into the ID cache system now.
6855 All server_idlist_* routines uses ID cache now instead of
6856 traversing its own lists (those lists does not exist anymore).
6857 SilcIDList though still exists. Also, SilcXXXEntry's are
6860 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6862 * Finally made the SKE implementation compliant to the protocol
6863 specification. All mp integers are now binary encoded as
6864 opposed being HEX encoded.
6866 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6869 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6870 functions: silc_[encode/decode]_pem. Also added function
6871 silc_encode_pem_file to PEM encode with newlines ('\n') for
6874 * SILC public keys are now encoded either PEM or binary. Same
6875 option is for private keys as well. By default private keys
6876 are binary encoded and public keys PEM encoded. Silly HEX
6877 encoding were removed.
6879 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6880 function to create fingerprints.
6882 * Fixed a bug in SHA1; does not change the original data anymore.
6884 * Partly implemented INFO command on client and server side.
6885 Fixed CLEAR command. Changes to SERVER command; show current
6886 server(s) when giving command without arguments. Added
6887 VERSION command to client.
6889 * Added check to server that unregistered connections cannot
6890 execute commands (unless it is specificly allowed).
6892 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6894 * Fixed screen refresh.
6896 * Fixed channel joining bug from client. On some circumstances
6897 client tried to join to a channel it had already joined.
6899 * Added public key verification process into client's protocol.c.
6900 The client now verifies the public key from user and saves
6901 it into ~./silc/serverkeys/ directory.
6903 Added into: clientutil.[ch]: silc_client_verify_server_key.
6905 * Changed SKE protocol's silc_ske_initiator_finish function
6906 to accept callback function that verifies the received public
6907 key. Removed old silc_ske_verify_public_key function.
6909 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6911 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6912 silc_pkcs_private_key[_data]_set.
6914 * Made the password and public authentication more cleaner in
6915 server's protocol.c.
6917 * Removed historic and obsolete protocol `channel_auth' from
6918 both client and server.
6920 * Removed wrong way of sending command status messages from
6921 server to client in server's command.c. The old way violated
6922 protocol specification.
6924 Changes to silccore/silccommand.[ch]: removed
6925 silc_command_encode_status_payload -> not needed anymore,
6926 changed silc_command_encode_payload_va to accept extra
6927 argument on variable argument list. The argument type must
6928 now be provided to the function. Also, added new function:
6929 silc_command_encode_reply_payload_va which is same as
6930 normal command_encode_payload_va except command status type
6931 is provided as extra argument.
6933 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6935 * Added ~./silc directory handling. The directory includes the
6936 public and private keys for the client.
6938 Added silc_client_check_silc_dir, silc_client_create_identifier
6939 and silc_client_load_keys.
6941 * Implemented SILC protocol compliant public key. Added public
6942 and private key saving to and loading from files.
6944 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6945 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6946 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6947 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6948 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6950 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6951 silc_pkcs_load_[public/private]_key.
6953 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6955 * Added silc_server_get_route (route.[ch]) to get connection
6956 data for the fastest route for given ID.
6958 * Implemented INVITE command on client and server. The command
6959 were re-defined in the SILC Protocol Specification and the
6960 implementation now complies with the specification.
6962 * Implemented PING command on client and server.
6964 * Implemented NAMES command on client and server. The server side
6965 supports currently only normal server not router server yet.
6966 Some changes to NAMES definition in SILC protocol specification.
6968 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6970 * Implemented LEAVE command on client and server.
6972 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6973 again. This change was made to the protocol as well. Server
6974 should not violate the protocol specification anymore.
6976 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6978 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6979 was tested. SOCKS4 was not but should work anyway.
