1 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed private message handling. It used some old code that
4 caused the client to crash. Affecte file is
5 lib/silcclient/client_prvmsg.c.
7 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
9 * Added function silc_client_add_channel,
10 silc_client_replace_channel_id, and removed functions
11 silc_client_new_channel_id and silc_idlist_get_channel_by_id
14 * Added cross reference of the joined channels to the
15 SilcClientEntry, and changed the SilcChannelEntry's
16 users list to SilcHashTable. The affected files are
17 lib/silcclient/idlist.[ch].
19 * Fixed a bug in hash table tarversing. While the hash table
20 is traversed with SilcHashTableList the table must not be
21 rehashed. It is now guaranteed that auto rehashable tables
22 are not rehashed while tarversing the list. Also defined that
23 silc_hash_table_rehash must not be called while tarversing
24 the table. Added function silc_hash_table_list_reset that must
25 be called after the tarversing is over. The affected files are
26 lib/silcutil/silchashtable.[ch].
28 * Changed all hash table traversing to call the new
29 silc_hash_table_list_reset in server and in client library.
31 * Added function silc_client_on_channel to return the
32 SilcChannelUser entry if the specified client entry is joined
33 on the specified channel. This is exported to application as
34 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
36 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
38 * Fixed founder regaining problem with JOIN command on normal
39 server. The notify for mode change must be sent always and
40 not only if !cmd->pending. Affected file silcd/command.c.
42 * Fixed the WHOWAS command's reply sending to support the
43 lists correctly. Affected file silcd/command.c.
45 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
47 * When sending JOIN command to router for processing the
48 sender's old command identifier was not saved back to the
49 sender's command context, fixed now. The affected file is
52 * Create the key in JOIN command of the router did not return
53 the channel key, added check for this. Affected file is
56 * Fixed a channel ID update bug in JOIN command reply. Do
57 not directly upgrade the ID but call the function
58 silc_idlist_replace_channel_id if the ID was changed.
59 Affected file silcd/command_reply.c.
61 * Fixed memory leaks from command calling if it would fail.
62 Affected file silcd/command.c.
64 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
66 * Applied patches from cras:
68 Memory leak fixes around libaries, irssi window resize fix,
69 new silclist.h and silcdlist.h, all extern inline changed to
72 * Removed dotconf from lib/dotconf, not needed anymore.
74 * Removed TRQ from lib/trq, not needed anymore.
76 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
77 with server connections. Later this will be configurable
78 in config file after new config file is done. Affected file
81 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
83 * Fixed a crash in server related to channel announcements.
84 Affected file silcd/server.c.
86 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
88 * Fixed memory leaks in silc_server_create_new_channel*
89 functions. Affected file silcd/server.c.
91 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
92 which ID was changed. This way the router will send the
93 user list for the channel again, and server won't be in
94 desync in some rare circumstances. Affected file is
95 silcd/packet_receive.c.
97 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
99 * Check for NULL socket pointer in the function
100 silc_server_packet_send_to_channel_real. Affected file
103 * Fixed the BAN notify handling to correctly remove ban
104 list. Affected file silcd/packet_receive.c.
106 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
108 * Fixed some header addition to Toolkit distribution in
109 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
111 * Added lib/silcclient/client_ops_example.h as an template
112 file for application programmers to quickly start using
113 the SilcClientOperation functions in their application.
114 Updated the lib/silcclient/README as well to tell about this
115 nice file made available.
117 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
119 * Call silc_server_remove_from_channels when removing client
120 entry when NO_SUCH_CLIENT_ID was received. Affected file
121 is silcd/command_reply.c.
123 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
125 * Added server & router operator statistics updating. Affected
126 file silcd/packet_receive.c and silcd/command.c.
128 * Fixed the SERVER_SIGNOFF notify handling on normal server
129 not to save the history information for clients. Same was
130 fixed earlier in remove_clients_by_server function, but not
131 here. Affected file silcd/packet_receive.c.
133 * Raised the default connection-retry count from 4 to 7 in
134 server. Affected file silcd/server.h.
136 * Cancel any possible reconnect timeouts when we start the
137 key exchange. Affected file silcd/server.c.
139 * Do not reconnect on connection failure when SCONNECT was
140 given. Affected files silcd/server.[ch].
142 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
144 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
146 * Fixed the NICK command to always give the unformatted
147 nickname to the one giving the NICK command. If unformatted
148 nickname is cached already it will be formatted and the
149 local entry will always get the unformatted nickname.
150 Affected file lib/silcclient/idlist.c.
152 * Fixed some double frees from client library commands.
153 Affected file is lib/silcclient/command.c.
155 * Fixed CUMODE command in server to assure that no one can
156 change founder's mode than the founder itself, there was a
157 little bug. Affected file silcd/command.c.
159 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
161 * Removed the SilcClientCommandDestructor from the client
162 libary, it is not needed anymore. Affected files are
163 lib/silcclient/silcapi.h, command[_reply].[ch],
164 client_notify, idlist.c.
166 * Fixed GETKEY command to first resolve client, and then
167 resolve the server only if the client was not found, instead
168 of resolving both at the same time. Affected file is
169 lib/silcclient/command.c.
171 * Added silc_client_start_key_exchange_cb and lookup the
172 remote hostname and IP address before starting the key
173 exchange with server. The affected file is
174 lib/silcclient/client.c.
176 * The server's public key is now saved using the IP address
177 of the server and not the servername for the filename.
178 The hostname public key filename is checked as an fall back
179 method if the IP address based filename is not found.
181 Fixed the GETKEY command to save the fetched server key
184 Print the remote server's hostname now when new key is
185 received during connection process. Affected file is
186 irssi/src/silc/core/client_ops.c.
188 * Return always our own public key to the client if it asks
189 for it with GETKEY command. Affected file silcd/command.c.
191 * Removed the use_auto_addr variable from default config
192 file since it was in wrong section. Affected file is
195 * Fixed TOPIC_CHANGE notification to not route it when it
196 was sent using silc_server_send_notify_to_channel function.
197 Affected file silcd/command.c.
199 * Fixed silc_server_send_notify_kicked to send the kicker's
200 Client ID also, it was missing. Affected files are
201 silcd/command.c, silcd/packet_send.[ch].
203 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
205 * Do not save client history information in SERVER_SIGNOFF.
206 Fixes the bug in normal server that it does not detect
207 the client becoming valid after the server becomes back
208 online. Affected file silcd/server_util.c.
210 * Added `sock_error' field into the SilcSocketConnection
211 context. When error occurs during socket operation (read
212 or write) the error is saved. Added also new function
213 silc_socket_get_error to return human readable socket error
214 message. Affected files are lib/silcutil/silcsockconn.[ch],
215 lib/silcutil/unix/silcunixsockconn.c, and
216 lib/silcutil/win32/silcwin32sockconn.c.
218 * The server now prints the socket error message in the
219 signoff for client. Affected file silcd/server.c.
221 * Fixed the `created' channel information sending from router
222 to server in JOIN command. Checks now whether the channel
223 really was created or not and set it according that.
225 Fixed the JOIN command to use the client entry's current
226 ID during the joining procedure instead of the one it sent
227 in the command (it is checked though), since it can change
228 between the packet processing and command processing, and
229 would just case unnecessary pain in the client end. Affected
230 file silcd/command.c.
232 * Fixed a channel key payload sending to use correct channel
233 ID when the server was forced to change the channel's ID by
234 router. Router sent the key payload with the old Channel ID.
235 Affected file silcd/packet_receive.c.
237 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
239 * Call silc_server_save_channel_key only if the key payload
240 was provided in the JOIN command's command reply. Affected
241 file silcd/command_reply.c.
243 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
245 * Fixed silc_mp_sizeinbase to return the value correctly with
246 MPI. Affected file lib/silcmath/mp_mpi.c.
248 * Fixed the stop_server signal to correctly stop the scheduler
249 and gracefully stop the server when SIGTERM or SIGINT signals
250 are received. Affected file silcd/silcd.c.
252 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
254 * Simple handling of TERM and HUP signals. Also added some log
255 flushing call around. Affected file is
258 * Fixed small bugs in silclog.c. Now buffering output will take
259 effect after 10 seconds since startup: This will ensure that
260 no important startup messages are lost. Also output redirection
261 will preserve original format ([Date] [Type] message).
262 Affected file is lib/silcutil/silclog.c.
264 * Added two options to the config file, in the logging section:
265 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
266 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
268 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
270 * Do not print the warning about log files not being initialized
271 more than once to avoid excess logging. Affected file is
272 lib/silcutil/silclog.c.
274 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
275 the SIM copying in make install in Makefile.am.pre.
277 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
279 * Rewritten silclog APIs. Globally interesting changes follows:
280 silc_log_set_files() changed to silc_log_set_file().
281 silc_log_set_callbacks() changed to silc_log_set_callback().
282 ROBOdoc documented silclog header file.
283 SilcLogCb now returns bool to wether inihibit the default
284 handler or not (to keep the old behaviour return always TRUE).
285 The new APIs should also fix the problem of the
286 silcd_error.log file that was written in the current directory.
289 Log files streams will remain opened after silc_log_set_file()
290 call, means less CPU usage notably on high traffic servers.
291 File streams are now full buffered, and flushed to the disk
292 every 5 minutes, lesses HD activity and CPU usage.
293 Messages can be redirected, allowing admins to configure
294 one single logfile for all server messages.
295 the silc_log_quick global variable to activate fast-logging.
296 Affected files lib/silcutil/silclog.[ch]
298 * Changed some code to conform new silclog APIs. Affected
299 files are doc/example_silcd.conf.in, silcd/server.c
300 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
303 * Fixed a memory leak that could occur in some situations.
304 Affected file silcd/serverconfig.c.
306 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
308 * Added the silc_client_del_client to remove the client from
309 all channels as well. Affected file lib/silcclient/idlist.c.
311 * Fixed the client library to correctly remove the client
312 from all channels when the client entry is being destroyed.
313 Affected file lib/silcclient/client_notify.c, command.c.
315 * Added auto-nicking support to the client library. If the
316 applicatio now sets client->nickname it will be sent to the
317 server after connecting by the library. This way for example
318 SILCNICK (or IRCNICK) environment variables will have effect
319 and always change the nickname automatically to whatever
320 it is wanted. Affected file lib/silcclient/client.[ch].
322 * Renamed silc_server_command_bad_chars to the
323 silc_server_name_bad_chars and moved it to the
324 silcd/server_util.[ch]. Added also new function
325 silc_server_name_modify_bad to return nickname that
326 includes bad characters as new nickname without those
327 bad characters. This check and modify is now used in
328 silc_server_new_client when the username is initially set
329 as nickname, so it must be checked to be valid nickname.
330 Affected file silcd/packet_receive.c.
332 * The nickname length is now taken from the packet for real
333 and not trusted to strlen() since it clearly can return
334 wrong length for nickname including bad characters. This
335 also applies to channel names. Affected file silcd/command.c.
337 * Removed the lib/silcsilm/modules directory. Modules are now
338 compiled into the lib/silcsim. Fixed the copying of the
339 modules to follow symbolic links in Makefile.am.pre.
341 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
343 * Fixed silc_string_regexify list creation. Fixes bugs with
344 BAN and INVITE commands in server. The affected file is
345 lib/silcutil/unix/silcunixutil.c.
347 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
349 * Removed the command destructor entirely from the server's
350 command and command reply routines. It is not needed, and
351 its usage was buggy and caused crashes. Affected files are
352 silcd/command[_reply].[ch].
354 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
356 * Cancel protocol and NULL sock->protocol if timeout
357 occurred during protocol. Affected file silcd/server.c.
359 * Cancel protocol timeouts always before calling the final
360 callback, to assure that after final callback is called
361 no other state will be called for the protocol anymore.
362 Affected file silcd/protocol.c.
364 * Print error log if incoming connection configuration could
365 not be found. Affected file silcd/server.c.
367 * Fixed JOIN command to correctly save the founder mode
368 to the client on normal SILC server, when the channel
369 was created by the router. Affected file silcd/command.c.
371 * Fixed LIST command (hopefully) to send correct reply
372 packets. Affected file silcd/command.c.
374 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
376 * The silc_packet_receive_process now returns FALSE if the
377 read data was invalid packet, and TRUE if it was ok.
379 The server now checks that if unauthenticated connection
380 sends data and its processing fails the server will close
381 the connection since it could be a malicious flooder.
383 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
385 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
387 * Make sure the warning about error opening a log file is
388 printed only once and not everytime it fails (produces
389 too much useless log). Affected file lib/silcutil/silclog.c.
391 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
393 * Made the silc_server_daemonise() function more readable.
394 Affected file silcd/server.c.
396 * Pid file is now optional, the user may comment it out from
397 the config file. Removed define SILC_SERVER_PID_FILE, we
398 don't need a default any longer. Affected file
399 configure.in.pre, lib/Makefile.am.pre.
401 * Make some use of the pid file. The server now dies at startup
402 if it detects a valid pid file on his path. The server would
403 die anyway in this circumstance, because of the bind() failure.
404 Affected file silcd/silcd.c.
406 * No longer compiling lib/dotconf.
408 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
410 * Fixed JOIN command parsing not to crash. Affected file
411 lib/silcclient/command.c.
413 * Fied the NICK_CHANGE notify to add the new client entry
414 even it is resolved. This removes an <[unknown]> nick
415 thingy bug in the client. Affected file is
416 lib/silcclient/client_notify.c.
418 * Do not try to allocate 0 bytes (efence does not like it)
419 in lib/silccore/silccomand.c when encoding payload.
421 * Do not take IRCNICK as nickname in Irssi SILC client since
422 it is not possible to set nickname before hand connecting
423 the server (TODO has an entry about adding auto-nicking
426 * Changed the silc_server_command_pending to check whether
427 there already exists an pending entry with the specified
428 command, command identifier and pending callback. This is
429 to fix IDENTIFY and WHOIS related crashes that may register
430 multiple pending commands with same identifier. Affected
431 file silcd/command.c.
433 * Fixed the server to reconnect to the router even if it
434 was already reconnecting and EOF was received. This to
435 fix a possibility that the server wouldn't ever try to
436 auto-reconnect to the router. Affected file silcd/server.c.
438 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
440 * Fixed the server's password authentication to use the
441 length of the locally saved password, and not the one
442 sent in the packet. Affected file silcd/protocol.c.
444 * Fixed same password authentication problem in the
445 Authentication Payload handling routines in
446 lib/silccore/silcauth.c.
448 * Yet another password authentication problem fixed with
449 channel password handling in silcd/command.c.
451 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
453 * If first character of string in silc_parse_userfqdn is '@'
454 then do not parse it. Affected file is
455 lib/silcutil/silcutil.c.
457 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
459 * Fixed minor bug in IDENTIFY command reply sending, which
460 caused various weird problems during JOIN when it was
461 resolving names for users. Affected file silcd/command.c.
463 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
465 * Fixed the IDENTIFY command reply sending to chech better valid
466 clients. It was possible to send incomplete list of replies.
467 Affected file silcd/command.c.
469 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
471 * Added silc_client_command[s]_[un]register functions now to
472 dynamically register the commands in client library. Removed
473 the static table of commands. This allows the client library
474 to call commands without causing the application to know about
475 what commands library has called.
477 Removed the INFO command reply kludge to detect when the command
478 was called by library. Now library use its own command reply
479 function for INFO command.
481 Added function silc_client_command_call to call a command.
482 Application can use it to call command, not access the structure
485 Now all commands that are sent by the client library (not
486 explicitly sent by application) use own command reply functions.
488 Affected files around lib/silcclient/ and in
489 irssi/src/silc/core/.
491 * Fixed the WHOIS command reply sending to chech better valid
492 clients. It was possible to send incomplete list of replies.
494 Fixed the WHOIS and IDENTIFY to send the request to router
495 if normal server did not do it and did not find any results.
497 Affected file silcd/command.c.
499 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
501 * Moved the internal data from SilcClient context into its
502 own file, not accesible to application. Affected files
503 lib/silcclient/client.h and lib/silcclient/client_internal.h,
504 and other files in client library.
506 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
508 * Added doc/examples installation target in Makefile.am.pre.
511 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
513 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
514 commands the found client entry will be removed from the
515 cache, after notifying application about the error. Affected
516 file lib/silcclient/command_reply.c.
518 * Changed the /MSG to check for exact nickname user gave, and
519 not let `nick' match `nick@host' if it is only one found. Now,
520 user must type the exact nickname (like nick@host2) even if
521 there are no more than one same nicks found. This is to avoid
522 a possibility of sending nickname to wrong nickname since
523 `nick' could match `nick@host'. Affected file is
524 irssi/src/core/silc-servers.c.
526 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
528 * Do not print "you are now server operator" or similar when
529 giving /away command. Affected files are
530 irssi/src/silc/core/client_ops.c, silc-servers.h.
532 * Made the silc_server_command_pending_error_check to send
533 the same command reply payload it received back to the
534 original sender of the command. This way all arguments
535 that was received by the server will be received by the
536 client too. Affected file silcd/command.c.
538 * Added the silc_idcache_add to return the created cache entry
539 to a pointer. Affected file lib/silccore/silcidcache.[ch].
541 * Add global clients to expire if they are not on any channel.
542 This is because normal server will never know if they signoff
543 if they are not on any channel. The cache expiry will take
544 case of these entries. This is done by normal servers only.
545 The affected files are silcd/command_reply.c,
546 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
548 * If server receives invalid ID notification for WHOIS or
549 IDENTIFY and the ID exists in the lists, it is removed.
550 Affected file silcd/command_reply.c.
552 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
553 in client then client entry that it matches is searched and
554 the nickname is printed on the screen for user. Affected
555 file irssi/src/silc/core/client_ops.c.
557 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
559 * Use cache entry expire time in the LIST command reply to
560 purge old entries from the cache after the LIST command
561 reply has been received. This way we don't have non-existent
562 entries in the cache for too long. Affected file is
563 silcd/command_reply.c.
565 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
567 * If we are normal server, and we've not resolved client info
568 in WHOIS or IDENTIFY from router, and it is global client,
569 we'll check whether it is on some channel. If it is not
570 then we cannot be sure about its validity and will resolve it
571 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
572 file silcd/command.c.
574 * Search channel by name (if possible) rather than by ID
575 in IDENTIFY command's command reply. Affected file is
576 silcd/command_reply.c.
578 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
580 * Distribute to the channel passphrase in CMODE_CHANGE notify.
581 Updated specs and implemented it. Affected file silcd/command.c,
582 silcd/packet_send.c and silcd/packet_receive.c.
584 * Implemented the <founder auth> payload handling in the JOIN
585 command. If provided all conditions for channel joining
586 except requirement to provide correct passphrase can be
587 overrided by the channel founder. Updated the protocol specs.
588 Affected file silcd/command.c.
590 Added support for founder auth in JOIN command in client
591 library. Fixed the parsing of the JOIN command now to support
592 all options as they should be. The affected file is
593 lib/silcclient/command.c.
595 * Optimized the WHOIS and IDENTIFY commands to send the request
596 to router only if it includes nicknames or other names. If
597 they include only IDs then check the local cache first before
598 routing. Affected file is silcd/command.c.
600 * Added channels topic announcements. Affected file is
601 silcd/packet_receive.c and silcd/server.c.
603 * Fixed the silc_server_send_notify_topic_set to really destine
604 the packet to channel. Affected file silcd/packet_send.c.
606 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
607 library. Affected file lib/silcclient/client_notify.c.
609 * Added UMODE announcements. Affected file silcd/server.c.
611 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>

615 lib/silcutil/silcsockconn.c
616 lib/silcske/silcske.c
619 lib/silccrypt/silcpkcs.c
620 lib/silccore/silccommand.c
621 lib/silccore/silcidcache.c
626 * ROBOdoc documented the lib/silcske/groups.h file and a
627 bit changed the interface for better.
629 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
631 * Update the client entry context in the ID cache after
632 nick change. Affected file lib/silcclient/command.c.
633 Fixes the CUMODE command when regaining founder privileges,
634 and a little WHOIS problem.
636 * Fixed silc_net_gethostbyname to correctly call the
637 inet_ntop. Affected file lib/silcutil/silcnet.c.
639 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
641 * Added IPv6 support checking to the configure.in.pre, added
642 also --enable-ipv6 option to override the check. Affected
643 file configure.in.pre.
645 * The silc_thread_create now calls the start function
646 directly if threads support is not compiled in. Removes
647 ugly #ifdef's from generic code. Affected files are
648 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
650 * Added silc_net_gethostby[name/addr]_async to asynchronously
651 resolve. Affected files are lib/silcutil/silcnet.[ch].

662 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
663 routines. Added silc_net_is_ip[4/6]. Affected file is
664 lib/silcutil/unix/silcunixnet.c. All routines that take
665 address as argument now supports both IPv4 and IPv6 addresses.
667 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
669 * Fixed LIST command reply sending in server. Affected file
672 * Server now sends the kicker's client ID in the KICK notify
673 to the kicked client. Affected file silcd/command.c.
675 * The client library now parses the kickers client ID and
676 UI displays it. Affected files lib/silcclient/client_notify.c
677 and irssi/src/silc/core/silc-channels.c, module-formats.c.
679 * Made all payload parsing function prototypes consistent.
680 They all take now const unsigned char * and uint32 pair as
681 the payload data instead of SilcBuffer. Changes all around
682 the source tree. Other unsigned char* -> const unsigned char*
683 changes around the tree as well.
685 * Optimized SFTP client and server packet sending not to
686 allocate new buffer for each packet but to recycle the
687 first allocated buffer. Affected files are
688 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
690 * Optimized the SFTP client to use SilcList instead of
691 SilcDList for requests, because it is faster. Affected file
692 is lib/silcsftp/sftp_client.c.
694 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
695 into lib/silccore/silcid.[ch].
697 Renamed silcpayload.[ch] into silcargument.[ch].
699 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
701 * If client entry is deleted with active key agreement
702 session, abort the session.
704 The silc_client_abort_key_agreement now calls the completion
705 callback with new SILC_KEY_AGREEMENT_ABORTED status.
707 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
710 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
712 * Don't use __restrict in older GCC's. Affected file is
713 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
715 * silc_net_localhost now attempts to reverse lookup the
716 IP/hostname. Affected file lib/silcutil/silcnet.c.
718 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
719 command. It can be used to gain founder privileges at
720 the same time when joining the channel.
722 Defined that the SILC_NOTIFY_TYPE_KICKED send the
723 kicker's client ID as well. Updated protocol specs.
725 Defined that the server must send SILC_COMMAND_IDENTIFY
726 command reply with error status to client who sent
727 private message with invalid client ID.
729 Updated the protocol specification.
731 * Added silc_server_send_command_reply to send any
732 command reply. Affected file silcd/packet_send.[ch].
734 * Added silc_id_payload_encode_data to encode ID payload
735 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
737 * The server now send IDENTIFY command reply with error
738 status if client ID in private message is invalid. Affected
739 file silcd/packet_receive.c.
741 * Save the server key file with server's IP address in
742 the filename instead of hostname. The affected file is
743 irssi/src/silc/core/client_ops.c.
745 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
747 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
750 * Added libtool support for compiling shared objects in
751 lib/silcsim. Affected file configure.in.pre and
752 lib/silcsim/Makefile.am. Original patch by cras.
754 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
756 * Pid file configuration, and server's config file fixes
757 patch by toma. Updated CREDITS file.
759 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
761 * Fixed silc_client_channel_message to not try to decrypt
762 the message twice if it resolved the destination client
763 information. This could cause of dropping one channel
764 message. Affected file lib/silcclient/client_channel.c.
766 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
768 * Added silc_client_run_one into lib/silcclient/silcapi.h and
769 lib/silcclient/client.c. This function is used when the SILC
770 Client is run under some other scheduler, or event loop or
771 main loop. On GUI applications, for example this may be
772 desired to used to run the client under the GUI application's
773 main loop. Typically the GUI application would register an
774 idle task that calls this function multiple times in a second
775 to quickly process the SILC specific data.
777 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
779 * Fixed silc_server_drop() for dropping the supplementary
780 groups as well, this could cause a security hole on some
783 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
785 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
788 * Write PID file after dropping privileges. Added -F option
789 to run server on foreground. A patch by debolaz.
790 Affected files silcd/server.c, silcd/silcd.c.
792 * Fixed MOTD to return the MOTD file server name. Affected
793 file silcd/command.c.
795 * Added INFO command reply handling to the Irssi SILC Client.
796 Affected file irssi/src/silc/core/client_ops.c.
798 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
800 * Fixed the silc_idcache_list_* routines to really support
801 the dynamic list. Fixes a crash. Affected file is
802 lib/silccore/silcidcache.c.
804 * Fixed the LIST command reply to really call LIST command's
805 pending callbacks. Affected file silcd/command_reply.c.
807 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
809 * Update conn->local_entry->nickname after giving NICK
810 command. Affected file lib/silcclient/command.c.
812 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
814 * Added the [pid] option to the silcd configuration file
816 Affected files: serverconfig.[ch] and silcd.c
818 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
820 * Save fingerprint in WHOIS command reply in server.
821 Affected file silcd/command_reply.c.
823 * Fixed NICK commands pending callback registration.
824 Affected file lib/silcclient/command.c.
826 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
828 * Use ++server->cmd_ident when sending commands in server,
829 instead of random number. Affected file silcd/command.c.
831 * Fixed GETKEY command reply to call actually GETKEY pending
832 command callbacks. Affected file silcd/command_reply.c.
834 * A bit stricter check for nicknames. Check for same nickname
835 in NICK command also. Affected file silcd/command.c.
837 * Do not call INFO command everytime client ID changes, only
838 during first connecting. Affected file lib/silcclient/client.c.
840 * Set the new nickname only after successful command reply for
841 NICK command is returned by server. Affected file
842 lib/silcclient/command.c.
844 * Remove nicknames from nicklist during server_signoff notify.
845 Should fix /NAMES bit more. The affected file is
846 irssi/src/silc/core/silc-channels.c.
848 * Added `fingerprint' field to the SilcIDListData in the
849 silcd/idlist.h to hold the fingerprint of the client's
852 Send the fingerprint of the client's public key in WHOIS
855 Affected files silcd/command.c, and silcd/idlist.[ch].
857 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
858 create fingerprint from given data.
860 * Show the fingerprint of the client's public key in WHOIS.
861 Affected files irssi/src/module-formats.[ch] and
862 irssi/src/silc/core/client_ops.c.
864 * Format the multiple same nicknames also during JOIN and
865 NICK_CHANGE notifys. Affected file is
866 lib/silcclient/client_notify.c.
868 * Do not print error on screen for invalid private message
869 payload since it can come if someone is sending private
870 messages with wrong key. Affected file
871 lib/silccore/silcprivate.c.
873 * Fixed multiple concurrent /PING crash. Affected file
874 lib/silcclient/command.c.
876 * Changed the wrong ID encoding. All IP addresses must be
877 in MSB first order in encoded format. They were encoded
878 wrong and was in LSB format. Affected files are
879 silcd/serverid.c, lib/silcutil/silcutil.c.
881 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
883 * Call the `connect' client operation through the scheduler
884 in case of error. Affected file lib/silcclient/client.c.
886 * Call the `failure' client operation even if the error
887 occurred locally during a protocol. Affected file is
888 lib/silcclient/protocol.c.
890 * Added support of sending LIST command to router from normal
891 server. This way normal server can get list of all channels
892 in the network too. Fixed the channel list sending in the
893 server too. Affected files are silcd/command.c, and
894 silcd/command_reply.[ch].
896 * Added silc_server_update_channels_by_server and
897 silc_server_remove_channels_by_server. They are used during
898 disconnection of primary router and in backup router protocol.
899 Affected file silcd/server_util.[ch], silcd/server.c and
900 silcd/server_backup.c.
902 * Fixed channel adding to global list in IDENTIFY command
903 reply in server. Affected file silcd/command_reply.c.
905 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
907 * If the incoming packet type is REKEY or REKEY_DONE process
908 that packet always synchronously. Fixes yet another MAC
909 failed error on slow (dialup) connections. Affected file
910 lib/silcclient/client.c and silcd/server.c.
912 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
914 * Call check_version SKE callback for initiator too. Affected
915 file lib/silcske/silcske.c.
917 * Implemented fix for security hole found in the SKE that was
918 fixed in the specification few days back; the initiator's
919 public key is now added to the HASH value computation.
920 Added backwards support for the old way of doing it too, for
921 old clients and old servers. Affected file is
922 lib/silcske/silcske.c.
924 * Enabled mutual authentication by default in SKE. If initiator
925 is not providing mutual authentication the responder will
926 force it. This will provide the proof of posession of the
927 private key for responder. The affected files are
928 lib/silcclient/protocol.c and silcd/protocol.c.
930 * Do not cache anymore the server's public key during SKE.
931 We do mutual authentication so the proof of posession of
932 private key is done, and if the server is authenticated in
933 conn auth protocol with public key we must have the public
934 key already. Affected file silcd/protocol.c.
936 * Added new global debug variable: silc_debug_hexdump. If
937 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
938 file lib/silcutil/silclog.[ch].
940 * Fixed compilation warning due to char * -> const char *.
941 Affected files lib/silcutil/silcnet.h, and
942 lib/silccore/silcauth.[ch].
944 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
946 * Fixed CMODE command when new channel key was created. If
947 the creation failed the old key was removed. Next time giving
948 same command would crash the server since the old key was
949 freed already. Affected file silcd/command.c.
951 * Fixed the silc_server_announce_get_channels to not crash
952 on reconnect. Affected file silcd/server.c.
954 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
956 * Added silc_log_set_debug_string function to set a regex
957 string to match for debug output. Only the function names,
958 or filenames matching the given debug string is actually
959 printed. This way it is possible to filter out those debug
960 strings that user is not interested in.
962 Fixed a bug in silc_string_regexify.
964 Affected files lib/silcutil/silclog.[ch], and
965 lib/silcutil/unix/silcunixutil.c.
967 * Changed the -d options in both server and Irssi SILC client
968 to take the debug string as argument. Affected files
969 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
971 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
973 * Added silc_hash_babbleprint to create a Bubble Babble
974 Encoded fingerprint. The encoding is developed by Antti
975 Huima (draft-huima-babble-01.txt), and it creates human
976 readable strings out of binary data. Affected file
977 lib/silccrypt/silchash.[ch].
979 * Print the babble print now in addition of fingerprint as well
980 in Irssi SILC client. Affected files are
981 irssi/src/fe-common/silc/module-formats.[ch],
982 irssi/src/fe-common/silc/core/client_ops.c.
984 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
986 * Fixed a security problem found in SKE. The initiator's
987 public key too is now added to the HASH hash value creation
988 which is signed by the responder to create the SIGN value.
989 This will prevent anyone in the middle to lie to the responder
990 about the initiator's public key. If this is done now, the
991 man in the middle will get caught. Updated the protocol
994 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
996 * Better installation directory handling. Configure module
997 paths and other paths automatically to example_silc* files
998 in doc/. A patch by toma.
1000 * Fixed compiler warning from MPI library, and from SILC RNG.
1003 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1004 It can be configured with ./configure. A patch by toma.
1006 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1008 * Find correct make to use in prepare-clean. A patch by
1009 toma. Affected file prepare-clean.
1011 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1013 * Added irssi variables use_auto_addr, auto_bind_ip,
1014 auto_bind_port and auto_public_ip.
1016 * Changed the interface for silc_client_send_key_agreement
1017 in lib/silcclient/silcapi.h
1021 irssi/src/silc/core/silc-core.c
1023 lib/silcclient/silcapi.h
1024 irssi/src/silc/core/silc-channels.c
1025 lib/silcclient/client_keyagr.c
1028 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1030 * Added silc_pkcs_public_key_compare to compare two
1031 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1033 * Check that the client who set the founder mode on the
1034 channel is the same client that is giving the founder
1035 mode to itself. It is done by comparing the saved public
1036 key (it is saved even in the authentication is passphrase).
1037 Affected file silcd/command.c.
1039 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1041 * Do not process packet for disconnected socket connection.
1042 Affected file lib/silccore/silcpacket.c.
1044 * Process the DISCONNECT packet through scheduler in the
1045 client library. Affected file lib/silcclient/client.c.
1047 * Fixed the silc_client_packet_parse to not to increase
1048 the packet sequence number if the conn->sock and the
1049 current socket connection is not same. This can happen
1050 for example during key agreement when the conn includes
1051 multiple socket connections (listeners). Affected file
1052 lib/silcclient/client.c.
1054 * The sender of the file transfer request now provides also
1055 the pointer (listener) for the key exchange protocol. If
1056 the listener cannot be created then it sends empty key
1057 agreement and lets the receiver provide the listener.
1059 Added `local_ip' and `local_port' arguments to the
1060 silc_client_file_send. If they are provided they are used,
1061 if not then it will attempt to find local IP address, if
1062 not found or bind fails then the remote client will provide
1065 Affected files are lib/silcclient/client_ftp.c and
1066 lib/silcclient/silcapi.h.
1068 * Extended the FILE SEND command to support defining the
1069 local IP and port for key exchange listener. They are
1070 optional. Affected file irssi/src/silc/core/silc-servers.c.
1072 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1074 * Defined to WHOIS command reply the sending of fingerprint
1075 of the client's public key (if the proof of posession of the
1076 corresponding private key is verified by the server).
1077 Updated to the protocol specification.
1079 * Added support of receiving the client's public key's
1080 fingerprint in command reply in client library. Affected
1081 file is lib/silcclient/command_reply.c, and
1082 lib/silcclient/idlist.[ch].
1084 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1086 * Do not send over 128 chars long nickname to the server
1087 in NICK command. Affected file lib/silcclient/command.c.
1089 * Do not send over 256 chars long channel names to the server
1090 in JOIN command. Affected file lib/silcclient/command.c.
1092 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1094 * Assure that silc_server_close_connection cannot be called
1095 twice for same socket context. Affected file is
1098 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1100 * Send error message to application if opening file for
1101 writing during file transfer fails. Affected file is
1102 lib/silcclient/client_ftp.c.
1104 Remove all file transfer sessions for a client that we're
1105 removing from ID cache.
1107 Affected file is lib/silcclient/client_ftp.c.
1109 * Fixed silc_net_addr2bin to return correct address. Affected
1110 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1112 * Fixed file transfer session removing on signoff notify.
1113 Affected file irssi/src/silc/core/silc-servers.c.
1115 * Added the SilcClientFileError to be returned in the monitor
1116 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1117 Affected file lib/silcclient/silcapi.h.
1119 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1121 * Fixed a crash in silc_client_ftp_free_sessions and
1122 silc_client_ftp_session_free_client. Affected file
1123 lib/silcclient/client_ftp.c.

1136 * Fixed a crash in client resolving in client_prvmsg.c in
1137 client library. Affected file lib/silcclient/client_prvmsg.c.
1139 * Do not actually remove the client directly from ID cache
1140 during SERVER_SIGNOFF, but invalidate it. This way we
1141 preserve the WHOWAS info for the client. Affected file
1142 silcd/server_util.c.
1144 * Fixed SERVER_SIGNOFF notify handling in the server. The
1145 server is now able to process incoming SERVER_SIGNOFF notify
1146 for a server that it doesn't even know about. It will remove
1147 the clients provided in the notify. Affected file
1148 silcd/packet_receive.c.
1150 * Check for partial packet in data queue after every packet that
1151 was found from the queue. Return and wait for more data if
1152 there is partial data in queue. Affected file is
1153 lib/silccore/silcpacket.c.
1155 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1157 * Added SilcClietFileError enum to indicate error in
1158 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT

1163 * Check that newsize in silc_buffer_realloc is larger than
1164 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1166 * Added better monitor of file transfers. It now monitors
1167 key agreement protocol during the file transfer too. Added
1168 error reporting too. Affected files
1169 irssi/src/silc/core/silc-servers.c,
1170 irssi/src/fe-common/silc/module-formats.[ch].
1172 * Wrote a help file for FILE command.
1174 * Added silc_rng_global_get_byte_fast to get not-so-secure
1175 random data as fast as possible. Random data is read from
1176 /dev/urandom if available and from the SILC RNG if not
1177 available. It is used in padding generation. Affected file
1178 lib/silccrypt/silcrng.[ch].
1180 * All packets in client library are now processed synchronously.
1181 Optimized packet processing a lot. Affected file
1182 lib/silcclient/client.c.
1184 * All server connection packets are processing synchronously
1185 now in server, to optimize packet processing. Affected file
1188 * Include files are installed now only in Toolkit distribution
1189 if make install is given. Affected files: all Makefile.am's.
1191 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1193 * Assure that silc_client_notify_by_server_resolve does not
1194 resolve the client information multiple times. If it cannot
1195 be found by the first it cannot be found at all. Affected
1196 file lib/silcclient/client_notify.c.
1198 * Fixed WHOWAS command reply calling. Affected file
1199 lib/silcclient/command_reply.c.
1201 * Removed all references to silc_idlist_get_client from the
1202 Irssi SILC client since that call is internal call used by
1203 the library. The Irssi SILC client will use now client
1204 retrieval functions found in silcapi.h.
1206 * Fixed a bug in resolving nickname info before sending
1207 private message. It used freed memory. Affected file
1208 irssi/src/silc/core/silc-servers.c.
1210 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1212 * Assure my_channels statistics cannot go negative in server.
1213 Affected files silcd/server.c, silcd/server_util.c.
1215 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1229 * Added silc_net_localip to return local host's IP address.
1230 Affected file lib/silcutil/silcnet.[ch].
1232 * If key exchange or rekey protocol is active for a connection
1233 parse all packets syncronously since there might be packets
1234 in packet queue that we are not able to process without first
1235 processing packets before them. Affected file silcd/server,
1236 lib/silcclient/client.c.
1238 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1239 whether library should continue processing the packet.
1240 Affected file lib/silccore/silcpacket.h.
1242 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

1271 lib/silcutil/silcutil.[ch].
1273 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1275 * Resolve the client info when received private message or
1276 channel message for a client which nickname we don't know.
1277 Affected files lib/silcclient/client_prvmsg.c and
1278 lib/silcclient/client_channel.c.

1281 file irssi/src/silc/core/silc-channels.c.
1283 * Added SilcClientStatus field to the SilcClientEntry in the
1284 lib/silcclient/idlist.h.
1286 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1287 is incomplete and is being resolved, it won't be resolved
1290 Make sure also that USERS command reply does not resolve
1291 twice information. Affected file is
1292 lib/silcclient/command_reply.c.
1294 Make sure that silc_client_get_clients_by_list does not
1295 resolve twice same information.
1297 * Check for valid client->id in the silc_server_free_client_data.
1298 Affected file silcd/server.c.
1300 * Fixed /GETKEY nick@server not to crash if the server entry
1301 is not found. Affected file lib/silcclient/command.c.
1303 * Fixed the silc_server_check_cmode_rights to check the
1304 requested modes correctly. Affected file silcd/command.c.
1306 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>

1309 Affected file silcd/command.c.
1311 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1313 * Call the silc_server_udpate_servers_by_server in the
1314 primary router that comes back online in the backup resuming
1315 protocol. Otherwise it routes packets wrong. Affected file
1316 silcd/server_util.[ch], silcd/server_backup.c.
1318 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1320 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1321 lib/silcutil/silcbuffmt.[ch].
1323 * Redefined the SILC packet header to include the padding
1324 length. Affected file lib/silccore/silcpacket.[ch].
1326 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1327 length for maximum padding up to 128 bytes). Affected
1328 file lib/silccore/silcpacket.h.
1330 * Removed all backwards support for old 0.5.x MAC thingies.
1331 The SILC packet header change makes it impossible to be
1332 backwards compatible.
1334 * Send the ENDING packet with timeout in the backup resuming
1335 protocol. This is to assure that all routers has connected
1336 to the primary router. Affected file silcd/server_backup.c.
1338 * Changed the RNG to take the first IV from random data. It
1339 used to take it from zero actually. Changed the RNG also
1340 to use /dev/urandom during session. /dev/random is used
1341 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1343 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1345 * Changed the SILC packet header to have the first two bytes
1346 (the packet length) encrypted. Affected files aroung the
1347 code tree, lib/silccore/silcpacket.[ch]. Removed the
1348 SilcPacketCheckDecrypt callback. It is not needed anymore
1349 since the silc_packet_receive_process will determine now
1350 whether the packet is normal or special.
1352 * Implemented the unidirectional MAC keys. Affected files
1353 lib/silcske/silcske.c, silcd/protocol.c and
1354 lib/silcclient/protocol.c.
1356 * Implemented the packet sequence number to the MAC computation.
1357 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1358 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1359 lib/silcclient/protocol.c.
1361 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1363 * Allow backup router to announce servers. All servers
1364 announced by backup router are added to the global list
1365 automatically. Update hte server's socket to our primary
1366 router also when backup router announces a server.
1367 Affected file silcd/packet_receive.c.
1369 * Do not update the client->router in the function
1370 silc_server_udpate_clients_by_server if the client is on
1371 global list. We might fail to find any specific server
1372 for locally connected clients and local cell clients. They
1373 should still use the `from' and not `to' as client->router.
1374 This fixes backup router resuming protocol. Affected file
1375 silcd/server_util.c.
1377 * Decrease channel statistics count only if the channel
1378 deletion worked. Affected files are silcd/server.c and
1379 silcd/server_util.c.
1381 * Added silc_server_update_servers_by_server to update origin
1382 of all server entries. Used during backup router protocol.
1383 Affected files silcd/server_util.[ch], silcd/server.c. and
1384 silcd/backup_router.c.
1386 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1387 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1388 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1389 lib/silccrypt/silchmac.c.
1391 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1393 * Assure that router cannot reroute the same channel message
1394 to the sender. Affected file silcd/packet_receive.c.
1396 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1398 * Made better checks that the channel message is not sent
1399 to the router it came from. Affected file is
1400 silcd/packet_send.c. Fixed memory leak too.
1402 * Announce informations for incoming router connection, but
1403 only after checking if it is replaced by backup router.
1404 Affected file silcd/packet_receive.c.
1406 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1408 * Fixed the backup resuming protocol to work in multiple
1409 router environment. Affected file silcd/server_backup.c.
1411 * Route packet only to one router in the function
1412 silc_server_packet_send_to_channel. Affected file is
1413 silcd/packet_send.c.
1415 * Fixed silc_server_send_notify_dest to set the broadcast
1416 flag. Fixed the silc_server_send_notify_topic to actually
1417 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1418 Affected file silcd/packet_send.c.
1420 * Changed the SFTP Filesystem interface. Changed the
1421 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1422 the filesystem operation function. The SilcSFTPFilesystem
1423 is now a context that is allocated by all filesystem allocation
1424 functions and it already includes the operations structure
1425 and filesystem specific context. It is given as argument
1426 now to the silc_sftp_server_start. This made the interface
1427 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1428 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1430 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1432 * Changed the backup router adding and getting interfaces
1433 in the server. The router that will be replaced by the
1434 specified backup router is now sent as argument. Affected
1435 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1438 * Added silc_net_addr2bin_ne to return the binary form of
1439 the IP address in network byte order. Affected files
1440 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1442 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1444 * Check for existing server ID in silc_server_new_server
1445 and in silc_server_connect_to_router_final and remove the
1446 old entry if it exists. Affected file silcd/packet_receive.c,
1449 * Send the channel message always to only one router, either
1450 in upstream or downstream. Affected file is
1451 silcd/packet_send.c.
1453 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1455 * Wrote the definition of the backup resuming protocol to the
1456 protocol specification.
1458 * Removed one redundant channel key generation from normal
1459 server during joining procedure. Removed one redundant
1460 channel key sending from server to router during joining
1461 procedure. Affected file silcd/command.c.
1463 * Made minor bugfixes to the backup router resuming protocol.
1464 Affected file silcd/server_backup.c, server.c.
1466 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1468 * Added --disable-asm configuration option. Affected files
1469 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1472 * Implemented the backup resuming protocol that is used to
1473 resume the primary router position in the cell after the
1474 primary router comes back online. Affected files
1475 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1476 and silcd/server_util.[ch].
1478 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1480 * Sleep two (2) seconds after sending QUIT command to server.
1481 Affected file lib/silcclient/command.c.
1483 * Assure that if outgoing data buffer is pending do not force
1484 send any data. Affected file silcd/packet_send.c.
1486 * Assure that if outgoing data buffer is pending do not force
1487 send any data. Affected file lib/silcclient/client.c.
1489 * Implemented the backup router support when the primary router
1490 goes down. The servers and routers can now use the backup
1491 router as new primary router without loosing connectivity.
1493 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1495 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1496 in the server to indicate disabled entry. All data read
1497 from the connection will be ignored and no data is sent
1498 for entry that is disabled. Affected files are
1499 silcd/idlist.h, silcd/server.c.
1501 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1503 * Created SFTP client and server test programs in the
1504 lib/silcsftp/tests directory.
1506 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1508 * Implemented memory filesystem (virtual filesystem) for
1509 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1512 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1514 * Implemented the SFTP (SSH File Transfer Protocol) to the
1515 lib/silcsftp. It includes SFTP client and SFTP server
1518 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1520 * Moved lib/silccore/silcprotocol.[ch] to the
1521 lib/silcutil library.
1523 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1524 take variable argument list pointer as argument. Affected
1525 file lib/silcutil/silcbuffmt.[ch].
1527 * Added silc_buffer_set function that is used to set data
1528 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1529 Affected file lib/silcutil/silcbuffer.h.
1531 * Changed various routines in the core library to use the new
1532 silc_buffer_set instead of allocating new buffer only for
1535 * Added 64-bit value formatting and unformatting support to the
1536 silc_buffer_[un]format routines. Affected file is
1537 lib/silcutil/silcbuffmt.[ch].
1539 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1540 to includes/bitmove.h.
1542 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1544 * Fixed channel user mode saving in client library. Affected
1545 file lib/silcclient/command[_reply].c.
1547 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1549 * Defined the file transfer to the SILC Protocol. Added
1550 new packet type SILC_PACKET_FTP and defined File Transfer
1551 Payload. The mandatory file transfer protocol is SFTP
1552 (SSH File Transfer Protocol). Affected file in addition
1553 of the internet draft is lib/silccore/silcpacket.h.
1555 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1556 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1557 is used as part of backup router protocol when the primary
1558 router of the cell is back online and wishes to resume
1559 the position as primary router.
1561 * Redefined the MAC generation keys in the protocol. The
1562 same key is not used anymore in both direction. Both
1563 direction will now use different keys for sending and
1564 receiving. This fixes a potential security flaw. This
1565 change causes incompatibilities in the protocol.
1567 * Redefined also the MAC computation from the packet.
1568 An packet sequence number is now added to the MAC
1569 computation. This prevents possible replay attacks against
1570 the protocol. This change too causes incompatibilities
1573 Added `sequence' field to the SilcPacketContext to hold
1574 the current sequence number for the packet.
1576 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1578 * Added `created' field to the SilcIDListData in the file
1579 silcd/idlist.h to indicate the time when the entry was
1582 * Added `created' field to the SilcChannelEntry too. Affected
1583 file silcd/idlist.h.
1585 * Added `creation_time' aguments to all the announcement functions
1586 in the server. If it is provided then only the entries that
1587 was created after the provided time frame are actually
1588 announced. Affected file silcd/server.[ch].
1590 * The protocol says that the Channel ID's IP address must be
1591 based on the router's IP address. Added check for this in
1592 the silc_server_new_channel when processing incoming New Channel
1593 Payload. Affected file silcd/packet_receive.c.
1595 * Print out the correct version with --version in SILC client.
1596 Affected file irssi/src/silc/core/silc-core.c.
1598 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1600 * Fixed WHOWAS command to check for completnes of the client
1601 entry always, not just when the command is coming from client.
1602 Affected file silcd/command.c.
1604 * Added new function silc_server_packet_queue_purge to purge the
1605 outgoing data queue to the network. After the function returns
1606 it is guaranteed that the outgoing packet queue is empty.
1607 Affected file silcd/packet_send.[ch].
1609 * Purge the outgoing packet queue in the rekey protocol's final
1610 callback to assure that all rekey packets go to the network
1611 before quitting the protocol. Affected file silcd/server.c.
1613 * Added silc_client_packet_queue_parse as similar function as
1614 in server to the client library. The affected file is
1615 lib/silcclient/client.c.
1617 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1619 * Splitted silcd/server.c and created silcd/server_util.[ch]
1620 for utility functions.
1622 * Added new socket flag SILC_SF_DISABLED to indicate that the
1623 connection is open but nothing can be sent to or received from
1624 the connection. Affected file lib/silcutil/silsockconn.[ch].
1625 The checking for disabled socket is checked in the low level
1626 silc_socket_write and silc_socket_read functions.
1628 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1630 * Allow only nicknames and channel names that fits into the
1631 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1633 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1635 * When processing JOIN command reply in server check that if
1636 the channel exists in our global list we'll move it the local
1637 list. Affected file silcd/command_reply.c.
1639 * Fixed the check whether client is joined on the channel already
1640 in JOIN command. Affected file lib/silcclient/command.c.
1642 * Fixed the JOIN command reply to check whether the channel
1643 already exists. Affected file lib/silcclient/command_reply.c.
1645 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1647 * Added silc_ske_status_string to map the SKE error numbers
1648 to readable strings. The affected files are
1649 lib/silcske/silcske[_status].[ch].
1651 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1653 * Do not show the private channels on the WHOIS channel list
1654 as it is not allowed by the protocol. The affected file is
1657 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1659 * Assure that the packet length digged from the actual packet
1660 is something sensible in the silc_packet_decrypt_rest_special
1661 in lib/silccrypt/silcpacket.c.
1663 * Free and NULL the allocated pointer in silc_hmac_alloc if
1664 the HMAC allocation fails. The affected file is
1665 lib/silccrypt/silchmac.c.
1667 * Print the selected security properties to the log files in
1668 the server. Affected file silcd/protocol.c.
1670 * Add SKE's reference counter even if calling the completion
1671 callback manually. Otherwise it goes negative, although it
1672 does not cause any problems. The affected file is
1673 lib/silcske/silcske.c.
1675 * Remove the client entry with short timeout after giving the
1676 KILL command. Affected file lib/silcclient/command.c.
1678 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1679 case all found clients are already disconnected (WHOWAS would
1680 found them) in the server. Affected file silcd/command.c.
1682 * Update the last_receive (time of last data received) to be
1683 updated only when received private or channel message so that
1684 the idle time showed in WHOIS makes more sense.
1686 * Added boolean field `valid' in to the SilcClientEntry in the
1687 client library to indicate whether the entry is valid or not.
1688 This fixes the nickname change bug on channel when changing
1689 the nickname to be same than the old (like nick to Nick) the
1690 nickname formatter doesn't set the new nick anymore to Nick@host.
1691 Affected file lib/silcclient/idlist.[ch].
1693 * Now actually fixed the nickname changing on disconnection.
1694 Added new function silc_change_nick to the Irssi SILC Client.
1695 Affected file irssi/src/silc/core/client_ops.c,
1696 irssi/src/silc/core/silc-nicklist.[ch].
1698 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1700 * Check that the public key exists in the GETKEY command before
1701 trying to encode it. Affected file silcd/command.c.
1703 * Print some notifications on received public keys with GETKEY
1704 command in the Irssi SILC Client. Affected files are
1705 irssi/src/fe-common/silc/module-formats.[ch],
1706 irssi/src/silc/core/client_ops.c.
1708 * Use IDENTIFY command to resolve the server information in the
1709 GETKEY command instead of INFO command. Affected file
1710 lib/silcclient/command.c.
1712 * All command reply functions in the client library now calls
1713 the pending command reply callbacks even if an error has
1714 occurred. The server has done this a long time and now it was
1715 time to move the client library to this as well. Now all
1716 errors can be delivered back to the pending command reply
1717 callbacks if necessary. Affected files are
1718 lib/silcclient/command[_reply].[ch].
1720 * Change the nickname on disconnection back to the username
1721 because in reconnect the server will enforce it to it anyway.
1722 Affected file irssi/src/silc/core/silc-servers.c.
1724 * Fixed a config file parsing bug in the Irssi SILC client.
1725 Affected file irssi/src/silc/core/clientconfig.c.
1727 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1729 * When printing the channel mode on JOIN, verify that the
1730 channel key and channel's HMAC are valid. Affected file
1731 irssi/src/silc/core/client_ops.c.
1733 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1735 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1736 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1737 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1739 * Removed channel key rekey task deleting from the function
1740 silc_server_save_channel_key. Affected file silcd/server.c.
1741 Added explicit timeout task context instead that is used to
1742 delete the task if we are registering a new task before the
1743 new task has elapsed.
1745 * When channel key rekey occurs the client library now saves
1746 the old channel key for a short period of time (10 seconds) and
1747 is able to use it in case some is still sending channel
1748 messages encrypted with the old key after the rekey. Affected
1749 file lib/silcclient/[idlist.h|client_channel.c].
1751 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1753 * Added check to the silc_server_new_id_real to not accept
1754 new ID if it is the sender's own ID. Affected file is
1755 silcd/packet_receive.c.
1757 * Assure that we do not announce ourself or the one we've
1758 sending our announcements when we're router and are announcing
1759 servers to our primary router. Affected file silcd/server.c.
1761 * Fixed silc_server_command_identify_check_client to assemble
1762 correct WHOIS packet. It send corrupted WHOIS packet and
1763 caused problem with router to router connections. Affected
1764 file silcd/command.c.
1766 Fixed also silc_server_command_whois_check the same way
1767 as for the IDENTIFY command.
1769 * Added new SilcIDListStatus to the server in the SilcIDListData
1770 structure. The status now includes the current status of
1771 the entry (like registered, resolved etc.). Affected file
1772 silcd/idlist.[ch]. Defined a bunch of different status types
1773 as well. This replaced the old boolean registered field as well.
1775 Added resolve_cmd_ident field to the SilcClientEntry structure
1776 too so that if the entry is for example being resolved so
1777 another command may attach to the same pending command reply
1778 without requiring to resolve the same entry again. This concept
1779 should optimize the WHOIS and the IDENTIFY resolving under
1780 heavy load by taking away unnecessary resolving for entries
1781 that are being resolved already.
1783 Added support for adding multiple pending commands for one
1784 command idenfier. Affected file silcd/command[_reply].[ch].
1786 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1787 before deleting the data. Otherwise the hash table will have
1788 freed data in comparison functions. Affected file is
1789 silcd/command_reply.c.
1791 * Fixed silc_idlist_replace_client_id to add the new entry to
1792 the cache with NULL nickname. Otherwise there will be invalid
1793 memory as the nickname after the nickname is freed. Affected
1794 file silcd/packet_receive.c.
1796 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1797 saved into wrong slots because the previous number of entries
1798 was not taken into account. Affected file silcd/idlist.c.
1799 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1801 * If we are router and we receive JOIN notify to a channel that
1802 does not have any users then notified client is marked as the
1803 channel founder, as it is it. The affected file is
1804 silcd/packet_receive.c
1806 * Added to the extended hash table API's table_del_*ext functions
1807 the destructor as argument too, so that the caller can decide
1808 which destructor to use or whether to use destructor at all.
1809 Affected file lib/silcutil/silchashtable.[ch].
1811 * Fixed ID Cache purging. It actually deleted the entries from
1812 the hash table after the data was freed. The hash table ended
1813 up comparing freed memory. The affected file is
1814 lib/silccore/silcidcache.c.
1816 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1818 * Fixed Irssi SILC client's KILL command's HELP syntax.
1820 * The USERS command now resolves the detailed user information
1821 if the userinfo field is missing. Affected file is
1822 lib/silcclient/command_reply.c.
1824 * Do not print error in silc_file_read if the read file does
1825 not exist. Just silently return NULL. Affected file is
1826 lib/silcutil/silcutil.c.
1828 * Fixed the silc_log_output to not wine about NULL filename
1829 and to not create some bogus " " filename. Affected file is
1830 lib/silcutil/silclog.c.
1832 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1834 * Fixed various printing bugs on the user interface in the
1835 Irssi SILC Client. Minor changes that were forgotten from
1838 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1840 * Fixed the configure.in.pre and the compilation and distribution
1841 environment to support the new autoconf 2.52. That version is
1842 now required to compile the CVS trunk.
1844 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1846 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1847 to generally parse user@fqdn format strings. Affected file
1848 lib/silcutil/silcutil.c.
1850 * Added nickname_format and nickname_force_format fields to the
1851 SilcClientParams structure. The first one defines the format
1852 for the nicknames that the library will enforce if the receives
1853 multiple same nicknames. The second one is boolean value and
1854 can be used to force the library to always enforce the format
1855 to the nicknames regardles whether there are multiple nicknames
1856 or not. This configurable formatting was employed to flexibly
1857 support accessing multiple nicknames from the user interface.
1858 The userinterface can now set the nicknames to what ever format
1859 they prefer. Affected file lib/silcclient/silcapi.h.
1861 Added function silc_client_nickname_format to the file
1862 lib/silcclient/idlist.c. It performs the nickname formatting.
1864 Added new field `hostname´ to the SilcClientEntry context.
1865 It holds the hostname of the client. Affected file is
1866 lib/silcclient/idlist.h.
1868 * Irssi SILC Client sets the nicknames in nick@hostn format.
1869 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1870 irssi/src/silc/core/silc-core.c.
1872 The WHOIS printing now also shows both the real nickname and
1873 the formatted nickname so that user knows how to access the
1874 user if there are multiple same nicknames cached. Affected
1875 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1876 printing formatting too to take the hostname now as a separate
1877 argument. The Affected file is
1878 irssi/src/fe-common/silc/modules-formats.[ch].
1880 * Changed the silc_client_get_clients_local to accept the formatted
1881 nickname as argument. It accepts the real nickname too but the
1882 formatted nickname can be used to find the true entry from
1883 multiple entries. Affected file lib/silcclient/silcapi.h and
1884 lib/silcclient/idlist.c.
1886 * Added nickname_format_parse field to the SilcClientParams.
1887 It is a callback function provided by the application to parse
1888 the nickname out of the formatted nickname string. The library
1889 calls it to get the nickname from the formatted string. Since
1890 the application generally knows better the format of the nickname
1891 string it parses it instead of the library, even though library
1892 encodes the formatted string. If the callback function is not
1893 provided then the library will use the string as is. The
1894 affected file is lib/silcclient/silcapi.h.
1896 * All the nickname strings passed to the client library in
1897 commands are now expected to be formatted nickname strings.
1898 If the command does not support the formatted nickname string
1899 it will assume that the sent string is the actual nickname.
1900 Affected file lib/silcclient/command.c.
1902 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1904 * Added public key authentication support to OPER and SILCOPER
1905 commands in the client library. Affected file is
1906 lib/silcclient/command.c.
1908 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1910 * Changed the get_auth_methdod client operation to be asynchronous.
1911 It can be async if the application resolves the authentication
1912 method from the server during the negotiation. Added new
1913 SilcGetAuthMeth completion callback that the application will
1914 call after resolving the authentication method.
1916 Added function silc_client_request_authentication_method that
1917 the application can use to resolve the authentication method
1918 from the server. Added also SilcConnectionAuthRequest callback
1919 that the library will call after the server has replied. The
1920 application can call this function if it does not know the
1921 current authentication method.
1923 Affected files are lib/silcclient/client.c and
1924 lib/silcclient/silcapi.h.
1926 * The Irssi SILC client now automatically resolves the authentication
1927 method incase any configuration information is not present (and
1928 currently there never is). The affected file is
1929 irssi/src/silc/core/client_ops.c.
1931 * Fixed public key authentication from the client library.
1932 Affected file lib/silcclient/protocol.c. Changed also the
1933 protocol specification about the public key authentication in
1934 the connection authentication protocol. The actual data to be
1935 signed is now computed with a hash function before signing.
1937 * Fixed the public key authentication from the server as well.
1938 Affected file silcd/protocol.c.
1940 * Removed the mlock()'s from the memory allocation routines.
1941 Affected file lib/silcutil/silcmemory.c. The ./configure does
1942 not check anymore for the mlock(). Affected file is
1945 * Fixed USERS command in server to allow the execution of the
1946 command for private and secret channels if the client sending
1947 the command is on the channel. Affected file silcd/command.c.
1949 * Fixed silc_client_get_clients_local to return the clients
1950 count correctly. It could return wrong value. Affected file
1951 lib/silcclient/idlist.c.
1953 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1955 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1956 types. The assembler optimizations seemed not to like 64-bit
1957 data types. The assmebler optimizations thus are now enabled
1958 also for BSD systems as opposed to only enable them for Linux.
1960 * Do not check for threads at all on BSD systems. Affected
1961 file configure.in.pre.
1963 * Removed -n and -h options from the Irssi SILC Client since
1964 they are not used in silc.
1966 * Fixed the prime generation to assure that the first digit
1967 of the generated random number is not zero since our conversion
1968 routines does not like number strings that starts with zero
1969 digit. If zero digit is seen the random number is regenerated.
1970 This caused some corrupted RSA keys when the zero first digit
1971 was met. Affected file lib/silcmath/silcprimegen.c.
1973 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1975 * Fixed WIN32 configuration in the ./configure script.
1976 Fixed to include xti.h on environments that has it.
1977 Patches by Carsten Ilchmann and andrew.
1979 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1981 * Changed the silc_id_create_client_id to be collision
1982 resistant. It is now assured that there cannot be created
1983 two same client ID's. I suspect that some weird bugs in
1984 the server were actually caused by duplicate Client IDs.
1985 Affected file silcd/serverid.[ch]. A router receiving
1986 new ID now also assures and informs the sending server
1987 if the ID caused collision.
1989 * Changed the silc_id_create_channel_id to also assure that
1990 there are no collisions.
1992 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1994 * Statement about ignoring the Mutual Authentication flag when
1995 performing rekey with PFS was a bit misleading. It is ignored
1996 if it was set in the initial negotiation, it cannot be even
1997 set in the rekey. Fixed in the ke-auth draft. Started the
1998 new versions of the protocol drafts in the doc/.
2000 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2002 * Fixed a bug in silc_client_command_identify_save when saving
2003 new channel information. The channel name was no duplicated
2004 and caused crash on exit. Affected file is
2005 lib/silcclient/command_reply.c.
2007 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2009 * Fixed the getkey command handling in the server. Send just
2010 empty OK reply to the sender if the key could not be fetched
2011 (but everything else was ok, like the key just was not available).
2012 Changed the public key parameter to optional in the protocol
2013 specs so that empty OK reply can be sent. Affected file
2016 Added a message to Irssi SILC client to tell to user if the
2017 server did not return a public key.
2019 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2021 * Fixed a channel key regeneration bug. It registered new
2022 timeout tasks exponentially until all system resources were
2023 used. Affected file silcd/server.c.
2025 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2027 * Added the SILC Document generator to the scripts/silcdoc.
2028 It can be used to generate the Toolkit Reference Manual out
2029 of the source tree. Internally it will also use the RoboDoc
2030 generator now imported in util/robodoc.
2032 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2034 * Added couple of return's in rekey protocol if error orccurred
2035 during the protocol. The execution must be terminated.
2036 Affected file silcd/protocol.c. Also, terminate the protocol
2037 always with timeout.
2039 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2041 * The client's Client ID was created initally from the wrong
2042 nickname (it could have been in format nick@host) in the
2043 silc_server_new_client. Affected file silcd/packet_receive.c
2045 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2047 * Added some SILC_LOG_ERROR's to various error conditions
2048 if client could not be added to ID cache. Affected files
2049 silcd/packet_receive.c and silcd/server.c.
2051 * When client's sock->user_data is freed, NULL also the
2052 client->router and client->connection pointers. Added check
2053 for these pointers being NULL to various places around the
2054 code. Affected file silcd/server.c.
2056 * Added client->data.registered == TRUE checks to various
2057 places around the code to assure that unregistered client's
2058 are not handled when it is not allowed. Affected file
2061 * Added `bool registered' fields to all
2062 silc_idlist_[server|client]_get_* routines to indicate whether
2063 the fetched client needs to be registered or not. Affected
2064 file silcd/idlist.[ch].
2066 * Add your own entry as registered to the ID cache in the
2067 server. Affected file server.c.
2069 * Fixed a bug in silc_server_new_server. The SilcServer was
2070 set as the new server's context instead of SilcServerEntry.
2071 This naturally caused some weird bugs.
2073 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2075 * Do not delete the channel rekey task when adding it
2076 for in silc_server_create_channel_key.
2078 * Changed the silc_server_create_channel_key to return
2079 TRUE or FALSE to indicate the success of the channel key
2082 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2084 * Fixed MSVC++ project files and added missing files to
2085 Makefiles under win32/.
2087 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2089 * Do not add TCP_NODELAY flag if the operating system
2090 does not have it defined. Affected files are
2091 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2093 * Fixed buffer overflow from Irssi SILC Client. Affected
2094 file irssi/src/fe-common/core/themes.c.
2096 * Fixed double free in client library in the file
2097 lib/silcclient/client.c when disconnecting from server.
2099 * Applied double free patch from cras to Irssi SILC client.
2100 Affected files irssi/src/core/[modules/expandos].c
2102 * Fixed the disconnection handling to Irssi SILC Client.
2103 The application must call silc_client_close_connection
2104 in ops->connect client operation in case of failure of
2105 the connection. Affected file is
2106 irssi/src/silc/core/client_ops.c.
2108 * Do not set sock->protocol to NULL in the function
2109 silc_client_close_connection after executing the protocol's
2110 final callback since the sock might not be valid anymore.
2111 Affected file lib/silcclient/client.c.
2113 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2115 * Do not enable SILC_THREADS if the linking with libpthread
2116 did not happen. Affected file configure.in.pre.
2118 * Added notion to protocol specification that server must
2119 verify the sent authentication payload with CMODE when
2120 setting the channel founder key. Implemented it to the
2121 server. Affected file silcd/command.c.
2123 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2125 * Added _EXTRA_DIST SILC distribution variable to the
2126 distributions file. It is used to conditionally add extra
2127 files or directories to the specific distribution. Affected
2128 files ./prepare, Makefile.am.pre and distributions.
2130 Removed the `_' from the start of the distribution names.
2133 * Added README.WIN32 for instructions to compile the Toolkit
2136 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2138 * Fixed a double free in disconnection in the server. Affected
2139 file is silcd/server.c.
2141 * Fixed the lib/silcske/groups.c to work now also with GMP
2142 MP library. The string conversion did not work when using
2143 specific base and the base is indicated in the string as well.
2145 * Created win32/ directory which now includes MSVC++ specific
2146 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2147 It will appear only in the toolkit distribution
2149 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2151 * Changed the key material distribution function in case when
2152 the hash output is too short. The data is now concatenated
2153 a bit differently than it used to. Made the change to the
2154 SKE protocol specification.
2156 * Added better GMP detection to configure.in.pre. A patch
2159 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2161 * Fixed a minor bug in SKE that might cause some problem on
2162 some platforms. Affected file lib/silcske/silcske.c.
2164 * Added the cookie checking for initiator in the SKE. It checks
2165 that the responder returns the sent cookie unmodified. The
2166 affected file is lib/silcske/silcske.c. Added new SKE
2167 error type INVALID_COOKIE that can be sent during the
2168 negotiation. Fixed some memory leaks as well.
2170 * Added the "invalid cookie" error message to Irssi SILC client's
2173 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2175 * Added `task_max' field to the SilcClientParams to indicate
2176 the maximum tasks the scheduler can handle. If set to zero,
2177 default values are used. Affected file lib/silcclient/silcapi.h.
2179 * Fixed memory leaks in silc_client_close_connection. Affected
2180 file lib/silcclient/client.c.
2182 * Added silc_client_del_client_entry to client library to free
2183 all memory of given client entry. Affected file is
2184 lib/silcclient/idlist.[ch].
2186 * Added new functions silc_client_del_channel and
2187 silc_client_del_server to delete channel and server entries.
2188 Affected file lib/silcclient/[silcapi.h/idlist.c].
2190 * Removed silc_client_del_client_by_id from silcapi.h.
2192 * Fixed the INFO command to return the server's own info
2193 correctly when querying by Server ID. Affected file is
2196 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2198 * Removed the non-blocking settings in WIN32 code in the
2199 silc_sock_[read/write] and added SleepEx instead. Affected
2200 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2201 of input data is now checked with FIONREAD and ioctlsocket.
2203 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2205 * Call silc_schedule_task_del_by_context in the
2206 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2207 Affected file lib/silccore/silcprotocol.c.
2209 * Call silc_protocol_cancel for active protocols in the
2210 silc_server_close_connection if the funtion
2211 silc_server_free_sock_user_data has not been called.
2212 Affected file silcd/server.c.
2214 * Generic tasks cannot be deleted using the del_by_fd
2215 task deleting function since generic tasks does not match
2216 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2218 * Added a notion to SILCOPER help file that the SILCOPER works
2219 only on router server, not on normal server.
2221 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2223 * Added for WIN32 support for the new scheduler as well.
2224 Affected file lib/silcutil/win32/silcwin32schedule.c.
2226 * Fixed the SHA1 implementation to work on various platforms.
2228 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2230 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2231 API. It is part of the scheduler now. Everything else is
2232 as previously but some functions has changed their names.
2233 Checkout the lib/silcutil/silcschedule.h for the interface.
2234 Updated all applications to use the new interface. Affected
2235 files are lib/silcutil/silcschedule.[ch].
2237 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2239 * Found a bug in the SKE implementation. The HASH value,
2240 specified by the protocol, was not computed correctly. The
2241 public key of the responder was not added to the computation
2242 even though it is mandatory. Affected file lib/silcske/silcske.c.
2243 This unfortunately causes incompatibilities with older
2244 clients and servers.
2246 * Added WIN32 specific network init and uninit functions:
2247 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2248 the Winsock2. Affected file lib/silcutil/silcnet.h and
2249 lib/silcutil/win32/silcwin32net.c.
2251 * Set the socket always to nonblocking mode on WIN32 after
2252 reading data or writing data. Affected file is
2253 lib/silcutil/win32/silcwin32sockconn.c.
2255 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2257 * Fixed various compilation problems under WIN32. Affected
2258 files lib/silcutil/win32/silcwin32thread.c and
2259 lib/silcutil/win32/silcwin32schedule.c.
2261 * Removed all _internal.h #includes from public header
2262 files. Internal headers must never be included from
2265 Removed also the lib/silcske/payload_internal.h file.
2267 * All include files that may be needed (public and some others
2268 included by the public headers) by application developers are
2269 now copied to the ./includes directory. It does not copy any
2270 internal headers. Affected file Makefile.defines.pre and all
2271 Makefile.am's under lib/ and subdirs.
2273 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2275 * Do not change the ~/.silc directory's permissions automatically.
2276 Affected file irssi/src/silc/core/clientutil.c.
2278 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2280 * Do not cancel the protocol in silc_server_close_connection
2281 it might cause recursion. Now cancelled in the function
2282 silc_server_free_sock_user_data. Affected file silcd/server.c.
2284 * Fixed the silc_server_remove_clients_by_server to regenerate
2285 the channel keys correctly finally. Added also new function
2286 silc_server_remove_clients_channels to actually do it.
2287 Affected file silcd/server.c.
2289 * Fixed the silc_server_new_channel to not crash by giving
2290 wrong router to the new channel. Affected file is
2291 silcd/packet_receive.c.
2293 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2295 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2296 which is given as argument to the silc_client_alloc now.
2297 It can be used to configure the client and set various parameters
2298 that affect the function of the client.
2300 * The USERS command in server did not check whether the channel
2301 is private or secret. Affected file silcd/command.c.
2303 * Added new argument to the USERS command in protocol specification.
2304 The USERS command now can take the channel name as argument
2305 as well. Added support for this in client and server and
2306 updated the protocol specs.
2308 * Completed the GETKEY command in client. It can be now used
2309 to fetch also servers public key not only some clients.
2310 Affected files lib/silcclient/command[_reply].c.
2312 * Added silc_client_get_server to return server entry by the
2313 server name. Affected files lib/silcclient/silcapi.h and
2316 * Redefined the IDENTIFY command in protocol specification to be
2317 more generic. It now can be used to query information about
2318 any entity in the SILC Network, including clients, servers and
2319 channels. The query may be based either the entity's name
2320 or the ID. Added support for this in both client and server.
2322 Affected files silcd/command.c and lib/silcclient/command.c
2323 and command_reply.c.
2325 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2326 the _from_client and _from_server functions. Affected file
2329 * Added silc_client_get_channel_by_id_resolve to the file
2330 lib/silcclient/silcapi.h to resolve channel information by
2331 its ID. Added also silc_client_get_channel_by_id that
2332 does not resolve it from the server.
2334 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2336 * Added SilcServerEntry context into the client library
2337 to represent one server. The INFO command now allocates
2338 these to save the resolved server info. For now on the
2339 client library will also keep information about servers,
2340 connected and resolved with INFO.
2342 The INFO command now allocates the SilcServerEntry context
2343 and saves the server info there. The COMMAND_REPLY in
2344 the INFO now returns the parameters to application in
2345 same order as defined in the protocol specification.
2347 The entries are cached in the client->server_cache.
2349 * The INFO command is now issued after received the Client ID
2350 from the server. Affected file lib/silcclient/client.c.
2352 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2353 to the application as the mode changer might be server.
2354 It is guaranteed that NULL is not returned anymore to the
2355 application. Affected file lib/silcclient/client_notify.c.
2357 The ID Type is now also passed to the application so that
2358 it can check whether the returned entry is SilcClientEntry
2361 Added new function silc_client_get_server_by_id to return
2362 the server entry by ID. Affected files are the
2363 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2365 * Do not create the channel in the Irssi SILC Client when issuing
2366 the JOIN command but when received the sucessful JOIN command
2367 reply. Otherwise the channel might get created even though we
2368 could not join it. The Affected file is
2369 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2371 * Fixed a channel joining bug in router. The router must also
2372 check the channel modes, invite and ban lists etc. when serving
2373 the JOIN command sent by normal server. Affected file is
2374 silcd/command.c. The router now resolves the client's
2375 information from the server who sent the JOIN command if it
2376 does not know it, and processes the JOIN command only after
2379 * Changed the SilcCommandCb to take new argument; void *context2.
2380 Affected file lib/silccore/silccommand.h
2382 The second argument in the command callbacks in the server now
2383 includes the SilcServerCommandReplyContext if the command was
2384 called as pending command callback from the command reply.
2385 Otherwise it is NULL. When called as pending the status of the
2386 command reply will be checked and if it was erronous the
2387 error will be sent to the original sender of the command.
2388 This way the client always receives the error messages even
2389 though the server was actually the one who received the error
2390 when it resent the command to router, for example. Affected
2391 files silcd/command[_reply].[ch].
2393 * Fixed sending WHOWAS command's error message to client if
2394 the requested client could not be found. It was missing.
2397 * Changed the CMODE and CUMODE commands reply arguments in the
2398 protocol specification. The Channel ID is now sent in both
2399 of the commands to identify the channel. Implemented this
2400 new feature to the client and server. Affected files
2401 lib/silcclient/command_reply.c and silcd/command.c.
2403 * Made better checks for invite and ban lists in the JOIN
2404 command in server. Affected file silcd/command.c.
2406 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2408 * The server now performs the incoming host IP/DNS lookup
2409 using the silc_socket_host_lookup and thus does not block
2410 the server anymore. Affected file silcd/server.c.
2412 * Completed the multi-thread support for SILC Scheduler in
2413 the lib/silcutil/silcschedule.c.
2415 * Fixed the configure.in.pre to detect the pthread correctly
2418 * Fixed a deadlock in silc_task_queue_wakeup in the file
2419 lib/silcutil/silctask.c.
2421 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2423 * Added new function silc_schedule_wakeup that is used in
2424 multi-threaded environment to wakeup the main thread's
2425 schduler. It needs to be used when a thread adds a new task
2426 or removes a task from task queues. After waking up, the
2427 scheduler will detect the task queue changes. If threads
2428 support is not compiled in this function has no effect.
2429 Implemented the wakeup mechanism to both Unix and WIN32
2430 systems. Affected files are lib/silcutil/silcschedule.[ch],
2431 lib/silcutil/unix/silcunixschedule.c and the
2432 lib/silcutil/win32/silcwin32schedule.c.
2434 * Added new function silc_task_queue_wakeup to wakeup the
2435 scheduler by the specified task queue. Affected file
2436 lib/silcutil/silctask.[ch].
2438 * The silc_socket_host_lookup_start now wakes up the scheduler
2439 after adding the timeout task. Affected file is
2440 lib/silcutil/silcsockconn.c.
2442 * The silc_socket_host_lookup is synchronous now if the threads
2443 support is not compiled in. However, the callback is still
2444 called asyncronously through the scheduler, anyway. Affected
2445 file lib/silcutil/silcsockconn.c.
2447 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2449 * Added new function silc_socket_host_lookup to perform
2450 asynchronous IP and FQDN lookups for the socket connection.
2451 Affected files lib/silcutil/silcsockconn.[ch].
2453 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2456 that may or may not compile the mutex support in.
2458 Changed the silc_mutex_alloc interface. It allocates the
2459 mutex now to the sent pointer and returns TRUE or FALSE.
2461 Affected file lib/silcutil/silcmutex.h.
2463 * Wrote the SILC Task Queue interface to support multi-threads.
2464 Affected file lib/silcutil/silctask.[ch].
2466 * Wrote the SILC Scheduler to support multi-threads. Affected
2467 file lib/silcutil/silcschedule.c.
2469 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2471 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2472 in lib/silcutil/win32/.
2474 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2476 * Defined SILC Mutex API and SILC Thread API and implemented
2477 them for Unix. Affected files are
2478 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2479 lib/silcutil/unix/silcunixmutex.c and
2480 lib/silcutil/unix/silcunixthread.c.
2482 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2484 * Fixed the silc_server_remove_clients_by_server's channel
2485 key re-generation. The hash table handling was incorrect
2486 and would not work with many channels. Affected file is
2489 * Fixed some memory leaks around the server code.
2491 * Rewrote the silc_server_get_users_on_channel to support IPv6
2492 based Client ID's. Affected file silcd/server.c.
2494 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2495 specification. However, a separate document must be written
2496 to define the detailed signing procedure and the payload
2497 associated with the flag. Defined the flag to the
2498 lib/silccore/silcchannel.h as well.
2500 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2502 * Changed the dynamic tables to static size tables in the
2503 lib/silccrypt/silchmac.c.
2505 * Removed GCC dependencies from the code. A patch by cras.
2507 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2509 * Do not show the error "Error receiving packet bla bla"
2510 in server if it really was not an error (-2 means that reading
2511 is pending). Affected file silcd/server.c.
2513 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2515 * Fixed a possible crash in silc_server_remove_clients_by_server
2516 in silcd/server.c. Fixed there also some memory leaks.
2518 * Fixed the silc_idlist_replace_client_id. It could replace
2519 wrong key in the hash table. Affected file silcd/idlist.c.
2521 * Do not check whether there are global users on the channel
2522 if the channel->global_users is FALSE. Affected functions
2523 silc_server_remove_from_one_channel and
2524 silc_server_remove_from_channels in silcd/server.c. Also,
2525 do not check if the removed client is local as we can be
2526 sure that global client was not removed from the channel
2527 and checking for global users is not needed.
2529 * The silc_server_remove_clients_by_server now re-generates
2530 the channel keys correctly for those channels that had
2531 clients removed from them. Affected file silcd/server.c.
2533 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2535 * Found the reason of random crashes in the server. We weren't
2536 ignoring the SIGPIPE signal (which can be sent in write())
2537 and it crashed the server. Affected file silcd/silcd.c.
2539 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2541 * Assure that sock->user_data is not NULL in the function
2542 silc_server_packet_send in silcd/packet_send.c.
2544 * Disconnect the remote connection if it could not be added
2545 to any ID lists in the server. The affected file is
2548 * Check in silc_server_packet_send[_real/dest] that the
2549 socket is not disconnecting and ignore the data if it is.
2550 Affected file silcd/packet_send.c.
2552 * Define inline to __inline on native WIN32 compilation.
2553 Affected file includes/silcwin32.h.
2555 * Added some explicit type casts for inline code since MSVC
2556 require them. Affected files lib/silcutil/silcbuffer.h,
2557 lib/trq/silcdlist.h and lib/trq/silclist.h.
2559 * Print warning in log files from now on if the packet
2560 decryption fails. Affected file silcd/server.c.
2562 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2564 * Changed the `say' client operation's interface to accept
2565 new `type' argument to indicate the type of the message sent
2566 by the library. The application may filter the library's
2567 messages according the type. The affected file is the
2568 lib/silcclient/silcapi.h.
2570 * Added two new functions to lib/silcclient/silcapi.h:
2571 silc_client_del_client and silc_client_del_client_by_id.
2572 Affected file lib/silcclient/idlist.c.
2574 * Moved the clientincludes.h from includes/ to silc/ and
2575 serverincludes.h from includes/ to silcd/.
2577 * The modes for the CMODE and CUMODE are now passed as
2578 uint32 for application with COMMAND_REPLY. The affected
2579 file is lib/silcclient/command_reply.c.
2581 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2583 * /WHOIS without arguments shows client's own information.
2584 Affected file lib/silcclient/command.c.
2586 * Changed PING to not accept any arguments. The specs
2587 says that client can ping only the connected server so
2588 requiring an argument is not needed. Affected file is
2589 lib/silcclient/command.c.
2591 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2593 * Fixed a fatal bug in private message sending and reception
2594 encryption and decryption when using private message keys.
2595 The implementation was incorrect and did not follow the
2596 specification. It causd that some of the message were
2597 lost since it did not use the sending and receiving keys
2598 as the protocol suggests. This has been fixed and will cause
2599 incompatibilities with older clients when sending private
2600 message encrypted with private message keys. Affected files
2601 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2602 and various other in Irssi SILC Client.
2604 Added `responder' boolean argument to the functions
2605 silc_client_add_private_message_key[_ske] to indicate when
2606 the key is added as responder or initiator of the key
2609 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Removed the silc_ske_check_version function and created
2612 a SilcSKECheckVersion callback. Added also a function
2613 silc_ske_set_callbacks that is now used to set all SKE
2614 callbacks. The callback functions are not given to
2615 the SKE functions anymore, but this function is used to
2618 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2620 * Added `silc_version' argument to the silc_client_alloc
2621 to define the version of the application for the library.
2622 The library will use the version string to compare it
2623 against the remote host's (usually a server) version
2624 string. Affected file lib/silcclient/silcapi.h
2626 * Added the KE protocol context to Key Agreement context
2627 in client library so that we can abort the SKE if it
2628 is in process when we get timeout. Affected file is
2629 lib/silcclient/client_keyagr.c.
2631 * Do not resolve the client ID forever if it returns in the
2632 first time that such client does not exist. This was done
2633 for example with private message. Affected file is
2634 lib/silcclient/client_prvmsg.c.
2636 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2638 * Do not add regex.h for WIN32. The affected file
2639 includes/silcincludes.h.
2641 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2642 not work yet 100%. It generates the DLL's automatically
2643 when compiling with --with-win32 under cygwin.
2645 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2647 * lib/contrib/regex.c is not compiled on WIN32.
2649 * Added silc_net_get_socket_opt function to the
2650 lib/silcutil/silcnet.h.
2652 * Added includes/silcwin32.h for WIN32 specific includes
2655 * Do not use ptime structure or any of the posix process
2656 functions on WIN32 in lib/silccrypt/silrng.c.
2658 * Added silc_gettimeofday to provide generic function
2659 for struct timeval on all platforms. Added the function
2660 to lib/silcutil/silcutil.h.
2662 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2664 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2665 library as they clearly belong there. As a plus side we
2666 can make the actual socket connection routines platform
2669 Added also new generic function silc_socket_read and
2670 silc_socket_write (that used to be silc_packet_[read/write].
2671 The implementation of these are platform specific.
2673 * Added WIN32 specific routines of silc_socket_[read/write]
2674 to lib/silcutil/win32/silcwin32sockconn.c.
2676 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2678 * Added preliminary support for native WIN32 compilation under
2679 cygwin (using the -mno-cygwin option for GCC) to the
2680 ./configure.in.pre. The --with-win32 now prepares the
2681 compilation for native WIN32.
2683 * Rewrote the SILC Scheduler interface in the file
2684 lib/silcutil/silcschedule.h. The scheduler is now context
2685 based and does not have anymore any global static scheduler.
2686 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2687 and created lib/silcutil/win32 directory for WIN32 based
2690 * Added Unix specific network routines to the
2691 lib/silcutil/unix/silcunixnet.c and the old
2692 lib/silcutil/silcnet.c includes now only generic routines.
2694 Added WIN32 specific network routines to the
2695 lib/silcutil/win32/silcwin32net.c.
2697 * Added Unix specific utility functions from the
2698 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2700 * Added WIN32 SILC Scheduler to the file
2701 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2704 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2706 * Do not handle JOIN notify in the server if the target client
2707 is not registered (idata->registered == FALSE). The affected
2708 file is silcd/packet_receive.c.
2710 * Update the nickrec->founder in event_cumode in the Irssi SILC
2711 client. Affected file irssi/src/silc/core/silc-channels.c.
2713 * Fixed the CUMODE_CHANGE notify handling in the server when
2714 server and router are announcing their clients on channels.
2715 Now the mode changes are saved and notified correctly. The
2716 affected file is /silcd/packet_receive.c.
2718 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2719 They really did not replace the cache entry in the ID Cache.
2720 Now they do that. Affected file silcd/idlist.c.
2722 * Fixed the KICK notify handling in the Irssi SILC client to
2723 update the channel records so that the kicked client does not
2724 appear to be on the channel. The affected file is
2725 irssi/src/silc/core/silc-channels.c.
2727 * Always update the conn->current_channel when executing command
2728 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2730 * Fixed the KILL notify handling in Irssi SILC client to remove
2731 the killed client on all channels.
2733 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2735 * Fixed the silc_parse_command_line to remove extra spaces
2736 from the start and end of the arguments. Affected file is
2737 lib/silcutil/silcutil.c.
2739 * Cancel and free any active protocol in the function
2740 silc_server_close_connection. Affected file silcd/server.c.
2742 * Cancel and free any active protocol in the function
2743 silc_client_close_connction. Affected file is
2744 lib/silcclient/client.c.
2746 * Do not execute the KILL command for clients that are in
2747 history (ie. they are not in the network). Affected file is
2750 * Fixed KILL notify handling, client does not crash anymore.
2751 Affected file irssi/src/silc/core/silc-channels.c.
2753 * Reduced the default packet buffer size from 2048 to 1024 in
2754 lib/silccore/silcpacket.c.
2756 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2757 counter to the SKE context that is incresed when the SKE library
2758 performs async operation outside the library. If the outside
2759 process frees the SKE context and FREED status will be set
2760 and the library will detect after the sync operation that the
2761 libary is freed. The affected files are
2762 lib/silcske/silcske[_status].[ch].
2764 * Resolve the client entry information in the function
2765 silc_client_channel_message to assure that NULL pointer is not
2766 passed as client entry to the application. */
2768 * Fixed the task timeout calculation to assure that there is
2769 never negative timeouts. The affected file is
2770 lib/silcutil/silcschedule.c.
2772 * Fixed the channel user mode notification sending in server.
2773 It was sent point-to-point to the router (or to server by router)
2774 but it needs to be destined to a channel. The routines now
2775 supports sending the channel user mode notifys to the channels
2776 when announcing clients and channels. Affected files are
2777 silcd/server.c and silcd/packet_receive.c.
2779 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2780 It did not actually replace the old channel entry in the cache.
2781 Affected file lib/silcclient/client_notify.c.
2783 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2785 * Fixed a possible crash in silc_packet_send_prepare. It now
2786 assures always that there is enough space in the buffer and
2787 at the tail area of the buffer (for MAC).
2789 Fixed the inbound buffer reallocation in silc_packet_read.
2790 It was old code and did not handle the reallocation correctly.
2793 The affected file is lib/silccore/silcpacket.c.
2795 * Fixed buffer overflow in silc_parse_nickname in the file
2796 lib/silcutil/silcutil.c.
2798 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2800 * make install generates new server keys only if there is not
2803 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2805 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2806 Added check that if the NOREPLY is set then we will not send
2807 the away message. This avoids infinite loop of away messages
2808 if both clients are away. The affected file is
2809 lib/silcclient/client_prvmsg.c.
2811 * Fixed client crash if /NICK was given without arguments.
2812 Affected file lib/silcclient/command.c.
2814 * Server does not send the invite list in INVITE command back
2815 to the client if the list was not altered. Added this notion
2816 to the protocol spec as well. Affected file silcd/command.c.
2818 Fixed possible crash in INVITE command by checking the
2819 value of silc_server_get_client_route command.
2821 * Fixed the INVITE notify type handling. The arguments are now
2822 taken in correct order and client does not crash. The affected
2823 file is irssi/src/silc/core/silc-channels.c.
2825 Removed the "Inviting xxx to channel" message from the
2826 client library away and let the application handle it.
2827 Affected file lib/silcclient/command.c. Added that message
2828 to Irssi SILC client's message formats.
2830 * Fixed CMODE command crash in client. It now checks the
2831 amount of arguments correctly and does not crash. The affected
2832 file is lib/silcclient/command.c.
2834 * Do not create new channel automatically in silc_channels_join
2835 but check whether the channel by that name already exists.
2836 Affected file irssi/silc/core/silc-channels.c.
2838 * Do not send the SERVER_SIGNOFF to router if the disconnected
2839 entity was the router. Affected file silcd/server.c.
2841 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2842 SILC client as it was missing from there.
2844 Added the handling of the KICK notify to the Irssi SILC client
2845 as it was missing. Added "you have been kicked" message to
2846 Irssi SILC client's message modules formats.
2848 Added the handing of the KILL notify to the Irssi SILC client
2849 as it was missing. Added the kill message module formats
2852 The affected file is irssi/src/silc/core/silc-channels.c.
2854 * The router did not save the channel mode the server announced.
2855 Affected file silcd/packet_receive.c.
2857 * Fixed a possible crash in INFO command in server. If the
2858 server did not provide the server info it crashed. Affected
2859 file silcd/command.c.
2861 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2863 * Fixed the GETKEY command in the server to check also the
2864 global list. Otherwise the GETKEY would not work correctly
2865 in normal SILC server. Affected file silcd/command.c.
2867 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2869 * Fixed GETKEY crash, it crashed if the command did not succseed.
2871 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2873 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2874 is now real and not just an macro interface to GMP.
2876 Removed the entire GMP from the source tree and imported new
2877 NSS MPI library instead. Reason for removing GMP is that it is
2878 extremely large and compiles extremely slow. The NSS MPI
2879 is only a few files and compiles in less than 10 seconds.
2880 The speed is also about the same as GMP. The MPI is imported
2881 to lib/silcmath/mpi.
2883 If the system has GMP installed we will still use the GMP.
2884 If it is not then the NSS MPI will be compiled.
2886 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2888 * Merged a long nickname (127 characters long) crash bugfix from
2889 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2891 * Merged a freed memory reference bugfix from Irssi CVS tree.
2892 Affected file irssi/src/core/commands.c.
2894 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2896 * Added the server's public key sving and verification to the
2897 server when performing the SKE. This was missing and the
2898 remote server's (or router's) public key was accepted without
2899 checking whether we have it previously or trust it at all.
2900 Affected file silcd/protocol.c.
2902 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2904 * Check in the silc_server_timeout_remote if protocol is active
2905 and make sure that the protocol's final callback is called so
2906 that all memory if freed. Affected file silcd/server.c.
2908 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2910 * silc_server_whois_send_reply crashed the server if the nickname
2911 was 127 characters long. Affected file silcd/command.c.
2913 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2915 * Added sanity check to the silc_server_new_client. If the hostname
2916 is provided inside username then check that the provided hostname
2917 really is the same as the resolved one. If the hostname was not
2918 resolved then check it from the public key. Affected file is
2919 silcd/packet_receive.c.
2921 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2922 if the server disconnected us and the connection is not valid
2923 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2925 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2926 the library to the lib/silcutil/silcutil.[ch].
2928 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2930 * Close log file after open. Affected file
2931 lib/silcutil/silclog.c.
2933 * Check whether sock == NULL in silc_client_send_packet and return
2934 if it is. Affected file lib/silcclient/silcclient.c.
2936 * Check rec->entry == NULL in the Irssi SILC Client before
2937 sending the channel message. Affecte file is
2938 irssi/src/silc/core/silc-servers.c.
2940 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2942 * Merged a splitted window bugfix from Irssi CVS tree. The
2943 affected file is irssi/src/fe-text/textbuffer-view.c.
2945 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2946 It did not print nickname.
2948 * Improved the distributions system a bit.
2950 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2952 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2953 irssi/src/fe-text/gui-window.c.
2955 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2956 to in-active server. The affected file is
2957 irssi/src/silc/core/client_ops.c.
2959 * Resolve the client in USERS command reply if the entry does
2960 not have username resolved. The affected file is
2961 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2962 command to WHOIS command to really resolve stuff. The USERS
2963 is not used any more in any critical section so WHOIS can
2964 be used even though it might be slower than IDENTIFY.
2966 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2969 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2971 * Changed the protocol API a bit more consistent in the
2972 lib/silccore/silcprotocol.[ch].
2974 * Changed the following headers to ROBODoc format:
2976 lib/silccore/silcpayload.h
2977 lib/silccore/silcprotocol.h
2978 lib/silccore/silcsockconn.h
2980 All core library headers are now formatted.
2982 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2984 * Fixed a bug in Irssi SILC client; do not show that you are
2985 server/router operator if you really are not. Affected file is
2986 irssi/src/silc/core/client_ops.c.
2988 * Renamed silc_command_free_payload to silc_command_payload_free.
2989 Affected file lib/silccore/silccommand.h
2991 * Added silcmath.h to include the prototoypes of various routines
2992 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2995 * Changed the following headers to ROBODoc format:
2997 lib/silccore/silcchannel.h
2998 lib/silccore/silccommand.h
2999 lib/silccore/silcid.h
3000 lib/silccore/silcidcache.h
3001 lib/silccore/silcmode.h
3002 lib/silccore/silcnotify.h
3003 lib/silccore/silcpacket.h
3004 lib/silcmath/silcmath.h
3006 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3008 * Added checking to the server code not to start the server if
3009 ciphers and stuff are not configured properly. Affected files
3010 silcd/serverconfig.[h] and silcd/server.c.
3012 * Changed the layout of the header files of the public interfaces
3013 in the SILC libraries. The new layout supports ROBODoc
3014 documentation tool (and some others) so that it is easy to create
3015 a library reference manual. All the other headers and source
3016 code must still follow the CodingStyle document. Also source
3017 code must not include these ROBODoc stuffs, only the headers.
3018 Furthermore, all public interface headers must now be named
3019 by using `silc' prefix, example: silcapi.h, silccipher.h.
3020 Some files were renamed due to this. All the other headers
3021 must not be used as public interfaces. I will update the
3022 CodingStyle document later. Changed following headers, so far:
3024 lib/silcclient/silcapi.h
3025 lib/silccore/silcauth.h
3026 lib/silccore/silcprivate.h
3027 lib/silccrypt/silcdh.h
3029 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3033 * Removed silc_client_packet_send_flush from the client library
3034 as it is not needed. Affected file lib/silcclient/client.[ch].
3036 * Added printing of message of unresolved authentication method
3037 to the Irssi SILC client. Added it to the module formats.
3038 Removed the same message from the client library.
3040 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3042 * Added new distribution feature, DISTLABEL. Every distribution
3043 can define own preprocessor label that can be used in the
3044 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3045 file distributions, acconfig.h.pre and prepare.
3047 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3049 * Added Makefile.defines_int to include the actual definitions
3050 for Makefile.defines.in. Tested the new distribution system,
3051 created distributions and tested installation.
3053 * Added AWAY message printing to the Irssi SILC client. Added
3054 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3056 * Added SCONNECT command to call the SILC's CONNECT command.
3057 Cannot use CONNECT directly since Irssi uses that internally.
3058 Affected file irssi/src/silc/core/silc-servers.c.
3060 Added ACTION local command. It is same as ME command but takes
3061 the channel as mandatory argument.
3063 Rewrote some of the Irssi's help files to suite for SILC
3066 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3068 * Added Makefile.defines[.in] that should for now on be included
3069 in all Makefile.am file in the source tree. That file includes
3070 all common compilation definitions for SILC source tree.
3072 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3074 * Minor changes to the ./prepare script to change the package
3075 name according the distribution name to the configure.in.
3077 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3079 * Created new distribution system. Added file `distributions'
3080 that defines all the distributions that can be created out of
3081 the SILC source tree. The ./prepare script now reads that
3082 file to determine how to prepare the distributions. The
3083 first argument to the ./prepare is the name of the distribution
3084 and second is the version of the distribution. If given
3085 without arguments it creates the default (toolkit) distribution
3086 with the default version (defined in ./prepare).
3088 All Makefile.am files that are subject to the distributions
3089 are now named as Makefile.am.pre. These are ./Makefile.am
3090 and lib/Makefile.am. Others may be changed later.
3092 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3094 * Added invite list, ban list, some key management and connection
3095 error message printing to module formats in the Irssi SILC client.
3097 * Added new silc_client_set_away_message to set the away message
3098 that is back to the person who sent private message. The
3099 affected file lib/silcclient/silcapi.h and the
3100 lib/silcclient/client_prvmsg.c.
3102 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3104 * Fixed the private message sending in the Irssi SILC client,
3105 added local command KEY to the Irssi SILC client.
3107 Added key management and key agreement message formats to the
3108 irssi/src/fe-common/silc/module-formats.[ch].
3110 Added USERS (alias WHO) printing, server/router operator
3111 indication and LIST command printing to the module formats.
3113 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3115 * Fixed channel joining notify handling, cumode notify handling
3116 from Irssi SILC client.
3118 * Added SILC specific module-formats to the Irssi SILC client so
3119 that SILC specific message hilighting, colors etc is possible.
3120 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3122 Added channel mode, channel user mode, actions, notices,
3123 whois and whowas printing to the the module-formats.c.
3125 * Fixed a bug in channel deletion in the server. The channel
3126 is not left to the cache even if the channel founder auth mode
3127 is set when there are no users anymore on the channel. Affected
3128 file silcd/server.c.
3130 * The silc_net_localhost now resolves the entire hostname including
3131 the domain name. Affected file lib/silcutil/silcnet.c.
3133 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3135 * Changed the ask_passphrase client operation to be ascynchronous.
3136 It has now a completion callback and a context that the
3137 application must call after it has got the passphrase from
3138 the user. Affected files lib/silcclient/silcapi.h,
3139 lib/silcclient/protocol.c, lib/silcclient/command.c and
3142 Added SilcAskPassphrase callback that the application calls
3143 to deliver the passphrase to the library.
3145 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3146 The public key verification and especially a certificate
3147 verification is asynchronous procedure.
3149 Added new SILC_SKE_STATUS_PENDING status to indicate the
3150 request is pending and a callback will be called to finalize
3153 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3154 indicate that remote end did not send its public key (or
3155 certificate), even though we require it. Added check for this
3156 condition in the SKE. This was a security bug, now fixed.
3158 Defined new SilcSKEVerifyCbCompletion callback that is called
3159 when the verification process is completed.
3161 The affected files lib/silcske/silcske_status.h and
3162 lib/silcske/silcske.[ch].
3164 * Changed the verify_public_key client operation to be async
3165 as well. Defined SilcVerifyPublicKey callback that is used to
3166 indicate the success of the public key verification process.
3168 Changed the server and client to use the new async client
3171 * Changed the Irssi SILC client's internal scheduler to be called
3172 twice as many times as it used to be. As a result the client
3173 should be a bit faster now. Affected file is
3174 irssi/src/silc/core/silc-core.c.
3176 * Added support to Irssi SILC client of asynchronous public key
3177 verification and passphrase inquiry. Affected file is
3178 irssi/src/silc/core/silc-core.c.
3180 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3182 * Do not say "You have left channel %s" in client library.
3183 Moved it to the application. Affected files are
3184 lib/silcclient/command.c and silc/client_ops.c.
3186 * Fixed silc_client_get_clients. Command context was not
3187 duplicated and was freed memory in the callback. Affected
3188 file lib/silcclient/idlist.c.
3190 * Do not say "you are now talking..." on JOIN command in the
3191 client library. The appliation must handle it.
3193 * Do not say ".. changed topic to" in command reply in the
3194 client libary. The application must handle it.
3196 * Fixed TOPIC command sending in the client library.
3198 * Fixed a memory leak in silc_client_command_free in the file
3199 lib/silcclient/command.c.
3201 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3203 * Imported a modified version of Irssi client to the source tree.
3204 The Irssi will be used to create a new client called
3205 Irssi SILC. Imported to irssi/.
3207 Added silc_core_init_finish function to the Irssi. Affected
3208 file irssi/configure.in.
3210 A lot changes in the Makefile.ams around the irssi tree.
3212 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3214 * Do not rehash if the new size is same as the old size of the
3215 hash table, in the silc_hash_table_rehash*. The affected file
3216 lib/silcutil/silchashtable.c.
3218 * Replaced hash_table_del_by_context calls from the server
3219 (when channel->user_list and client->channels) to the
3220 hash_table_del as it is sufficient and faster.
3222 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3224 * Added silc_hash_table_list, silc_hash_table_get and the
3225 SilcHashTableList structure to provide an alternative way to
3226 traverse the hash table. The affected files are
3227 lib/silcutil/silchashtable.[ch].
3229 * Changed the server's idlist routines to use the hash table
3230 routines to optimize the code.
3232 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3234 * Replaced the client entry's `channel' list and channel entry's
3235 `user_list' list to hash tables for optimized lookup. Changed
3236 the code to use the hash table interface around the code.
3237 Affected file lib/silcd/idlist.[ch].
3239 * Added `auto_rehash' boolean argument to the function
3240 silc_hash_table_alloc to indicate whether the hash table should
3241 auto-rehash when it thinks is appropriate time. It will
3242 increase the hash table size if the there is twice as much
3243 entries in the table than the size of the table, and will
3244 decrease the size if there are twice as less entries than
3245 the size of the table.
3247 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3249 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3251 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3253 * silc_idcache_purge_by_context deletes the entry now by context
3254 as it is supposed to do. Affected file lib/silccore/idcache.c.
3256 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3257 client is not anymore valid (WHOWAS givens the info) and not
3258 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3260 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3262 * Removed the `data' and `data_len' arguments from the ID Cache
3263 interfaces and added `name' argument. ID Cache does not handle
3264 anymore the binary data only a names associated with given ID.
3266 * When hashing a Client ID with silc_hash_id the entire ID is
3267 not hashed anymore, instead only the hash of the Client ID is
3268 hashed. This way we can access the Client ID from the cache
3269 with Client ID but with the hash of the ID (which is a hash of
3270 the nickname) as well without any difference in performance.
3272 Added also silc_idcache_find_by_id_one_ext to do one on one
3273 searching when we have the actual ID. Added also function
3274 silc_hash_client_id_compare. The affected files are
3275 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3277 * When hashing the name associated with a ID it is always done
3278 in lowercase. This way we can access the cache without worrying
3279 about case-sensitivity, even though, for example nicknames are
3282 * Fixed a bug in server with channel message sending. It put
3283 wrong ID type as destination ID. The affected file
3284 silcd/packet_send.c.
3286 * silc_idcache_del_by_context now deletes from all hash tables
3287 by context. Affected file lib/silccore/idcache.c.
3289 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3291 * Changed the client library to use the new ID Cache interface.
3292 Changes around the source tree.
3294 * Added silc_hash_table_rehash_ext to rehash with specific
3295 hash function. Affected file lib/silcutil/silchashtable.[ch].
3297 * Added silc_hash_string_compare to compare two strings in the
3298 hash table. Affected file lib/silcutil/silcutil.[ch].
3300 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Added new function silc_idcache_del_by_context into the
3303 lib/silccore/idcache.[ch].
3305 * Changed the server's ID list routines to use the new ID Cache
3306 interface. Changes around the source tree.
3308 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3310 * Added silc_hash_table_del[_by_context]_ext functions in to the
3311 lib/silcutil/silchashtable.[ch].
3313 Removed silc_hash_table_find_all* routines and added new
3314 silc_hash_table_find_foreach to replace them.
3316 Added silc_hash_table_replace_ext function as extended
3317 replacing function. Separated the simple hash table interface
3318 from the extended hash table interface in the file
3319 lib/silcutil/silchashtable.h.
3321 * Fixed minor bugs and changed it to use some of the new
3322 hash table functions in lib/silccore/idcache.c
3324 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Added new function silc_hash_table_find_all to return all keys
3327 in the hash table by the specified key. As the hash table is
3328 collision resistant it also makes it possible to have several
3329 duplicate keys in the hash table. This function may be used to
3330 find all of the keys from the hash.
3332 Added user_context arguments to the SilcHashFunction,
3333 SilcHashCompare and SilcHashDestructor to deliver user specified
3336 Added new fuctions silc_hash_table_find[_all]_ext to do
3337 extended lookup with specified hash and compare functions and
3338 specified user contexts.
3340 Added new function silc_hash_table_add_ext to add the key
3341 with specified hash function and user context.
3343 Added new function silc_hash_table_foreach to traverse all
3344 entrys in the hash table. Added SilcHashForeach callback
3347 Added new function silc_hash_table_del_by_context to delete
3348 the entry only if the context associated with the key matches.
3350 Affected files are lib/silcutil/silchashtable.[ch].
3352 * Removed silc_hash_[server/client/channel]_id and added just
3353 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3354 silc_hash_id_compare to compare two ID's using as the hash table
3355 comparison function. Added also silc_hash_data to hash
3356 binary data and silc_hash_data_compare to compare it.
3358 * Removed silc_idlist_find_client_by_hash as it is not needed
3359 anymore. Affected file silcd/idlist.[ch].
3361 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3362 to use internally the SilcHashTable. The new ID Cache is a lot
3363 faster than the old one. Some of the ID Cache interface was also
3364 rewritten and obsolete and stupid functions were removed.
3366 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3368 * Added entry_count field to the SilcHashTable to keep the number
3369 of the entries in the table. Implemented the function
3370 silc_hash_table_rehash. Added new function
3371 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3373 Fixed a minor bug in silc_hash_table_free.
3375 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3376 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3377 into the lib/silcutil/silcutil.[ch].
3379 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3381 * Implemented a collision resistant hash table into the
3382 lib/silcutil/silchashtable[ch]. See the header and the source
3383 for the SilcHashTable API.
3385 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3387 * Merged dotconf version 1.0.2 into lib/dotconf.
3389 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3391 * Do not compile anything in lib/silcsim/* if the SIM support
3392 is not enabled. The tree should now compile without problems
3395 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3397 * Compiled the SILC under cygwin. Compiled and tested briefly
3398 without problems. More tests needed. The SIMs didn't compile
3401 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3403 * Fixed possible crash in silc_get_username in the
3404 lib/silcutil/silcutil.c.
3406 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3408 * Fixed a va_arg in silc/client_ops.c.
3410 * Oops, RC5 routines were named AES and caused some problems
3411 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3413 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Added new SilcIDIP structure into the lib/silccore/id.h and
3416 replaced the old `ip' fields from all SILC ID's to that type.
3417 This is a step towards IPv6 support.
3419 The silc_id_get_len takes now the ID as an extra argument.
3420 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3421 both IPv4 and IPv6 based ID's.
3423 The affected files are lib/silccore/id.[ch] and other files
3424 around the tree using these routines.
3426 * Removed the ID length arguments in server from various
3427 silc_server_send_notify_* routines -> they are not needed
3430 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3432 * Fixed memory leak in silc_encode_pem_file in the file
3433 lib/silcutil/silcutil.c.
3435 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3437 * Check minor version as well in the SKE. Affected files are
3438 silcd/protocol.c and lib/silcclient/protocol.c.
3440 * Added --identifier option to the server so that an identifier
3441 can be when creating the public key for the server. Affected
3442 file is silcd/silcd.c.
3444 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3445 lib/silccrypt/silcpkcs.c.
3447 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3449 * Register default ciphers and stuff when using -C option with
3450 the server. Affected file sildc/silcd.c.
3452 * Put back the servers public key filename format, it is better
3453 than the new one. For now, the client keys are saved with the
3454 new filename format. The affected file silc/client_ops.c.
3456 * Implemented the Cipher API for the rest of the ciphers that
3457 did not implement it or implemented it the wrong way.
3459 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3461 * Register default ciphers and stuff when using the -S option
3462 in the client. Affected file silc/silc.c. Same also when
3463 creating new key pair with -C option.
3465 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3467 * Fixed the silc_verify_public_key client operation function to
3468 save the public keys differently. The fingerprint is now
3469 used as filename and not the hostname. This way also the
3470 client keys are saved uniquely and not with hostnames. The
3471 affected file is silc/client_ops.c.
3473 * Trimmed the silc_hash_fingerprint function to remove extra
3474 whitespaces from the end of the fingerprint. The affected
3475 file is lib/silccrypt/silchash.c.
3479 * Added silc_cipher_register_default function to register all
3480 default ciphers. It can be used when configuration files
3481 does not exist and the application does not want any specific
3482 ciphers in any specific order.
3484 The SilcDList is now used as silc_cipher_list dynamically
3485 allocated cipher list. Removed the static list all together
3486 and now all ciphers must be allocated to the dynamic list.
3487 The silc_cipher_alloc routine was changed to check only the
3490 All silc_cipher_* routines that used to return int returns
3493 The affected files lib/silccrypt/silccrypt.[ch].
3495 * The same thing was done to silc_hash_* as for silc_cipher_*
3496 routines. Affected files lib/silccrypt/silchash.[ch].
3498 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3499 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3500 Added also silc_pkcs_[un]register[_default] functions.
3501 Removed the data_context from the PKCS API.
3503 * Added silc_hmac_register_default function to register default
3504 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3505 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3506 to unregister all hmacs at once.
3508 * Register the default ciphers, hash functions, PKCSs and HMACs
3509 if client's configuration file does not exist. The affected
3512 * The client did not load the hash functions from the SIM
3513 modules at all. Added support for this. Affected file is
3514 silc/clientconfig.c.
3516 * When decoding public key with silc_pkcs_public_key_decode, check
3517 the supported algorithm only if PKCS are registered. Affected
3518 file lib/silccrypt/silcpkcs.c. The same was done with the
3519 silc_pkcs_private_key_decode.
3521 * Fixed the SILC List routines to keep the list always in order.
3522 It used to change the list's order when traversing the list but
3523 not it preserves the order. Affected file lib/trq/silclist.h.
3525 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3527 * Added the client library to use the SilcSocketConnection's
3528 reference counter (by silc_socket_dup) to prevent the bug that
3529 the socket object may be freed underneath async operation.
3531 * The name resolv library checking fixes in the configure.in.pre.
3534 * Created new version of the protocol drafts for future
3535 development. The -03 drafts are the ones that will be changed
3536 in the trunk now and the -02 will remain as they are.
3538 * Send list of CUMODE notifys to the router when announcing
3539 the channel users to the router. Affected file silcd/server.c.
3540 If the router receiving channel founder CUMODE for a channel
3541 that already has channel founder it will send CUMODE notify
3542 to the sender to remove the channel founder rights from the
3543 announced client. Affected file silcd/packet_receive.c.
3545 * The CUMODE notify may now use Server ID as well as the entity
3546 who changes the mode. Updated protocool specs.
3548 * Updated INSTALL and README files.
3550 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3552 * New web pages in the http://silc.pspt.fi. The pages was
3557 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3559 * Implemented the [DenyConnectin] config section in the server.
3560 Added silc_server_config_denied_conn to check whether incoming
3561 connection is denied. Affected file silcd/serverconfig.[ch].
3563 * Do not check the ports when checking the incoming configuration
3564 data if the port is 0, meaning any. Affected file is
3565 silcd/serverconfig.c.
3567 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3569 * Fixed buffer overflow in silc_string_compare in the file
3570 lib/silcutil/silcutil.c.
3572 * Fixed double free in silc_server_command_leave in the file
3575 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3577 * Fixed the version checking in the server. Affected file is
3580 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3582 * Fixed the configuration data fetching when accepting new
3583 connections in the server. Affected file silcd/server.c.
3585 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3587 * Added `sender_entry' argument to the function
3588 silc_server_packet_relay_to_channel so that we can check
3589 whether some destination actually belongs to the same route
3590 the sender belongs (ie, we must not resend the packet to the
3591 sender). Affected file silcd/packet_send.[ch].
3593 * Added `servername' field to the SilcClientEntry in the server
3594 to hold the name of the server where client is from. Affected
3595 file is silcd/idlist.h.
3597 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3599 * Moved the channel message encrypting in the router betwen
3600 router connections from silc_server_channel_message to the
3601 silc_server_packet_relay_to_channel since we want to check
3602 whether we have anybody channel before encrypting anything.
3603 Affected files silcd/packet_[receive/send].c.
3605 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3607 * Fixed the [AdminConnection] server config section to support
3608 multiple entries. Affected file silcd/serverconfig.c.
3610 * Added support into the server to check the validity of the
3611 incoming connection before executing any KE or authentication
3614 * The connection configuration is now saved to the KE and
3615 connection auth protocol contexts and not fetched anymore in
3616 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3618 * The local hosts listenning address and port is also resolved
3619 now when starting the server. We want to have the socket object
3620 to include the real address and port for the listener. Added
3621 new function silc_net_check_local_by_sock into the files
3622 lib/silcutil/silcnet.[ch].
3624 * Fixed a broadcast bug in server -> do not broadcast if we
3627 * Fixed a routing bug. Do not route broadcast packets ever.
3628 Broadcast packets must be processed always and not routed since
3629 they may be destined to some other host than yourself and thus
3630 would get routed without no good reason. Affected file is
3633 * Added function silc_server_config_is_primary_route to check
3634 whether primary router connection has been configured (a router
3635 configuration that we are initiating). If there is not, we
3636 will assume that there is only two routers in the SILC network
3637 and we will use the incoming router connection as our primary
3638 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3640 * Changed the order of the broadcasting. Broadcast _after_ the
3641 packet has been processed not before. Affected file is
3644 * Fixed a [ClientConnection] parsing bug. The port was never
3645 parsed correctly thus resulting to port 0. Affected file
3646 silcd/serverconfig.c.
3648 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3649 argument and did not set the broadcast packet flag. Affected
3650 file silcd/packet_send.c. Fixed same bug in the function
3651 silc_server_send_notify as well.
3653 * If we receive NEW_ID packet for our own ID in the server, ignore
3656 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3660 * Removed the nickname from the Private Message Payload.
3661 Updated the code and the protocol specs.
3663 * Updated protocol specs for submitting to the IETF.
3665 * Tweaked the Random Number Generator a bit. Affected file
3666 lib/silccrypt/silcrng.c. Exported a new function
3667 silc_rng_[global]_add_noise which can be used to add more
3670 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * Do not parse packets with different timeout when protocol
3673 is active -> may cause problem with rekey. Affected file
3676 * When server receives signoff notify it must not create
3677 new channel key if the client is on any channels since the
3678 sender of the signoff notify will create it.
3680 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3682 * Added printing of error messages during SKE protocol from the
3683 failure packet sent by server during SKE. Affected file
3686 * Removed the client's failure_callback handling with timeout
3687 and handle it immediately when received.
3689 * The SKE library returned wrong type in SUCCESS and FAILURE
3690 packets. They must be 32 bit MSB not 16 bit MSB.
3692 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3694 * Ok, rewrote the logic of the re-key and now it seems to work.
3695 I tested it on high traffic with frequent re-keys without
3696 problems. Added hmac_receive (and renamed hmac to hmac_send)
3697 in SilcClientConnection in lib/silcclient/client.h and
3698 in SilcIDListData in silcd/idlist.h. Also, removed the
3699 SilcPacketParserContext's cipher and hmac fields as they are
3700 not needed anymore and actually caused some problems when
3701 the ciphers and hmac's changed underneath the packet parser.
3703 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3705 * If re-key protocol is active then process the incoming packets
3706 synchronously since we must assure that icoming packets encrypted
3707 with the old key is processed before the new keys is set to
3708 use. This is true other packets than for REKEY packets.
3709 Affected file silcd/server.c. The same was done to client library
3710 as well, affected file lib/silcclient/client.c.
3712 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3714 * Fixed bug in client and server to accept the force send if
3715 the packet is send from silc_[server/client]_packet_process
3716 function. Otherwise the packets are never delivered, oops.
3718 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Disable force sending of packets when REKEY protocol is active.
3721 We must assure that no packet is sent directly when rekey is
3722 performed. All packets must be sent through packet queue.
3723 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3724 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3725 function is silc_[server/client]_packet_send_real to check
3728 * Replaced the SIM paths from example config files to
3729 /usr/local/modules. Also, make install creates now
3730 /usr/local/silc/logs directory to hold all the SILC server
3733 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

3744 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3746 * When MAC computation fails the silc_packet_decrypt returned 0
3747 even though it was supposed to return -1. Fixed this. The
3748 affected file is lib/silccore/silcpacket.c.
3750 * Do not replace the config files in /etc/silc (in make install)
3751 if they already exist. Affected file ./Makefile.am.
3753 * Do not send re-key packets immediately but through packet queue.
3754 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3756 * Changed silc_net_check_host_by_sock to return FALSE if the
3757 IP/DNS could not be resolved. Though, it returns the IP address
3758 now even if it could not resolve it (but returns also FALSE).
3759 Affected file lib/silcutil/silcnet.[ch].
3761 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Added silc_pkcs_decode_identifier to decode the public key's
3764 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3765 Added also silc_pkcs_free_identifier. Added also new context
3766 SilcPublicKeyIdentifier.
3768 * Added -S option to the silc client. It is used to dump the
3769 contents of the specified public key file.
3771 * Changed the PKCS api to return the public key length when
3772 setting the public key.
3774 * Fixed a fatal bug in the public and private key file loading.
3775 Affected file lib/silccrypt/silcpkcs.c.
3777 * Execute the packet parsing for client with zero (0) timeout
3778 if the protocol is active. Affected file silcd/server.c.
3780 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3782 * Made the key generation options to the silcd program. Added
3783 -C option, equivalent to client's option.
3785 * Added new [ServerKeys] config section to the server. It
3786 configures the server's public and private key.
3788 * Defined generic Public Key Payload into the protocol
3789 specification to send specific type of public keys and
3792 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3793 public key or certificate.
3795 * Implemented the GETKEY command to the server and to the
3796 client library and on user interface.
3798 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3800 * Made preliminary `make install' work.
3802 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3804 * Added SilcServerRekey context into silcd/idlist.h.
3806 * Added the PFS support as defined in the specification to the
3807 SKE protocol. Affected files lib/silcske/*.c.
3809 * Added `ske_group' field to the SilcServerRekey context to hold
3810 the number of the SKE group that is used with PFS in re-key.
3811 Affected file silcd/idlist.h.
3813 * Added PFS re-key support to the server. Affected file is
3816 * Added silc_protocol_cancel to cancel execution of the next
3817 state of the protocol. Affected file is
3818 lib/silccore/silcprotocol.[ch].
3820 * Added the re-key support with and without PFS to the client
3821 library. Re-key is performed once in an hour, by default.
3823 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3824 Added silc_client_rekey_callback and silc_client_rekey_final.
3825 Affected files are lib/silcclient/protocol.[ch] and
3826 lib/silcclient/client.[ch].
3828 * Removed the `hmac_key' and `hmac_key_len' fields from the
3829 SilcClientConnection structure; not needed. Affected file is
3830 lib/silcclient/client.h.
3834 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * Do not ask whether user wants to use the negotiated private key
3837 for private messages, just use it. Affected file is
3838 silc/local_command.c.
3840 * Added `send_enc_key' and `enc_key_len' fields to the
3841 SilcIDListData structure since they are needed in the re-key
3842 phase. Affected file is silcd/idlist.[ch].
3844 * Implemented the simple re-key protocol into the server.
3845 Affected files silcd/server.c and silcd/protocol.[ch]. The
3846 re-key will be performed once in an hour, by default.
3848 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3849 Added silc_server_rekey, silc_server_rekey_callback and
3850 silc_server_rekey_final.
3852 * Removed Tunneled flag from the protocol. Updated the code
3853 and the specifications.
3855 * Adde `pfs' field to the SilcIDListData to indicate whether
3856 the PFS is to be performed in the re-key. Affected file is
3859 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3861 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3862 int64 of at least the xintXX size. If void * is less that 4
3863 bytes uint32 * will be used. Defined bool as boolean.
3865 * Changed _ALL_ unsigned long and unsigned int to uint32,
3866 unsgined short to uint16 in the source tree.
3868 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3869 not handle clients that has entry->data.registered == FALSE.
3870 They are not in the network anymore. Affected file is
3873 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3875 * Implemented the sending of the SERVER_SIGNOFF notify in the
3876 server. Affected file is silcd/server.c.
3878 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3879 Added also silc_notify_payload_encode_args into the
3880 lib/silccore/silcnotify.[ch].
3882 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3883 Affected file silcd/packet_receive.c.
3885 * Implemented the SERVER_SIGNOFF notify handling in the client
3886 library. Affected file lib/silcclient/client_notify.c. Also,
3887 implemnted the printing of the SERVER_SIGNOFF info to the
3888 application. Affected file silc/client_ops.c.
3890 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3891 if the deleting was successful. Affected file silcd/idlist.[ch].
3893 * Added support for public key authentication in the connection
3894 authentication protocol in the client library. Affected file
3895 lib/silcclient/protocol.c.
3897 * Changed the server's silc_idlist_get_clients_by_* interface
3898 to support already allocated array so that new entries may be
3899 added to pre-allocated array. Affected file silcd/idlist.[ch].
3900 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3901 and command replies.
3903 * All command reply functions in the server now calls the
3904 pending command callback even if error occured. This way the
3905 error will be delivered to the client as well. Affected files
3906 silcd/command.c and silcd/command_reply.c.
3908 * Fixed INFO command to return local server's info if no server
3909 was provided. Affected file lib/silcclient/command.c.
3911 * Removed RESTART command for good. Updated the code and the
3914 * Rewrote parts of the task system. It is a bit simpler now.
3915 Removed unsued task priorities. The affected files are
3916 lib/silcutil/silctask.[ch].
3918 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3920 * Moved the USERS printing from the library to the application.
3921 Affected files lib/silcclient/command.c and silc/client_ops.c.
3923 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3927 * Added channel key re-key support. The re-key is perfomed
3928 only by the router and is done once in an hour. Added `rekey'
3929 field to the SilcChannelEntry in the server. Affected files
3930 silcd/server.c and silcd/idlist.h.
3932 * Added silc_task_unregister_by_context into the file
3933 lib/silcutil/silctask.[ch].
3935 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3937 * Added SILC_UMODE_GONE mode to indicate when the client is not
3938 present in the SILC network. Added also support to the local
3939 command AWAY that will set this mode. Added support of showing
3940 "xxx is gone" in WHOIS command. The USERS command shows the
3941 gone status as well.
3943 * Fixed setting server and router operator privileges in the
3944 server's UMODE command. Affected file silcd/command.c.
3946 * Merged the SKE KE1 and KE2 payloads into one payload. The
3947 new KE payload is equivalent to the old KE2 payload.
3949 Cleaned up the SKE Start Payload parsing. It now uses the
3950 simple buffer unformatting to do the parsing. A lot faster
3953 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3954 to the SKE that is used to indicate whether both of the SKE
3955 parties should perform authentication. By default only the
3956 responder performs authentication. By setting this flag also
3957 the initiator must do authentication. By default it is unset
3958 since in normal SKE case, client to server connection, only
3959 the responder should do authentication. When doing SKE between
3960 two clients both should perform authentication. Updated the
3961 code and the protocol specs.
3963 * A little fix to IDENTIFY command in the server. Search the
3964 client first by hash not nickname. Affected file is
3967 * Fixed the silc_client_close_connection to support closing
3968 the client to client connections wihtout deleting too much
3969 data. Affected file lib/silcclient/client.c.
3971 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3972 are received if protocol used to be active but is not anymore
3973 the application would crash due to NULL pointer dereference.
3974 Affected files silcd/server.c and lib/silcclient/client.c.
3976 * Added `hash' field to the SilcClientConnection to include
3977 the hash function negotiated in the SKE protocol.
3979 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3980 to set the channel founder authentication data. A client can
3981 claim the founder rights later by providing the authentication
3982 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3983 This way the channel founder can regain the channel founder
3984 privileges even it is left the channel. This works only on
3985 local server and the client must be connected to the same
3986 server to be able to regain the founder rights. Updated the
3987 protocol specs accordingly.
3989 Added support to the CMODE command in the client to set the
3990 founder auth data. Read the README to see how to set it.
3992 Added support to the CUMODE command to claim the founder
3993 rights. Read the README to see how to do it.
3995 Added support for the founder authentication to the Channel
3996 Entry in the server. Affected file silcd/idlist.h.
3998 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3999 server's CMODE command. Affected file silcd/command.c.
4001 * Added the following new functions into lib/silccore/silcauth.[ch]:
4002 silc_auth_get_method and silc_auth_get_data.
4004 * The server now saves the remote hosts public key to the
4005 SilcIDListData pointer. Affected file silcd/protocol.c.
4007 * The normal server now does not remove the channel entry from
4008 the cache if the founder authentication data is set. It used
4009 to remove it if the founder was the last one on the channel on
4010 the server and left the channel. The auth data is saved and
4011 if the channel is re-joined later the old entry is used with
4012 the old auth data. Affected files silcd/command_reply.c and
4015 * Removed the `pkcs' field from the SilcIDListData structure
4016 in the server; it is not used. Affected file silcd/idlist.h.
4018 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4020 * Fixed packet processing on slow links. Partial packets were
4021 never re-processed because the incoming data buffer was cleared
4022 by the application. Application must not directly clear the
4023 sock->inbuf, the packet processing routines handle it. Fixed
4024 this in client library and in server.
4026 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4028 * Fixed the WHOIS and IDENTIFY send reply function to really
4029 check whether to send list or just one entry. Affected file
4032 * Cleaned up the LEAVE command's channel key distribution. The
4033 affected file silcd/command.c.
4035 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4036 can enforce the channel mode as well. In that case the ID
4037 includes the ID of the server. The code now enforces the
4038 mode change if the router have different mode than the server.
4040 * The notify client operation with CMODE_CHANGE notify can now
4041 return NULL client_entry pointer if the CMODE was not changed
4042 by client. Application must check for this.
4044 * Added <Server ID> argument to INFO command to support server
4045 info fetching by Server ID.
4047 * Added silc_server_announce_get_channel_users to get assembled
4048 packets of channel users of the specified channel. Affected
4049 file silcd/server.[ch].
4051 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4052 was freed underneath the ID Cache.
4054 * Re-announce clients when the server received CHANNEL_CHANGE
4055 notify from the router. Affected file silcd/packet_send.c.
4057 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4059 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4060 crashed since it did not handle the fact that there is no cipher
4061 called "3" and didn't check the error condition. Now fixed.
4063 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4064 flag. It can be used to send message requests.
4066 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Implemented the RESTART command in the client.
4070 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4071 notice type messages. Added notice printing to the user
4074 * The channel keys are not re-generated if the channel's mode
4075 is PRIVKEY, ie private key on the channel exists. Affected
4076 files silcd/server.c and silcd/command.c.
4078 * Fixed a little bug in channel message delivery when channel
4079 private keys are set in the server. Affected file is
4080 silcd/packet_send.c.
4082 * Changed the setting on channel->on_channel = TRUE from the
4083 silc_client_save_channel_key to the JOIN command reply. The
4084 key payload is not received if the private channel key is set.
4085 Affected file lib/silcclient/command_reply.c and the
4086 lib/silcclient/client_channel.c.
4088 * When the CMODE_CHANGE notify is sent and the channel private
4089 key mode is removed the channel key must be re-generated in
4090 other cells as well. Added this support for the router in the
4091 silcd/packet_receive.c.
4093 * Added new local command NOTICE to send notice message on
4094 channel. Affected file silc/local_command.[ch].
4096 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4098 * Added new local command ME to the client. It is used to send
4099 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4100 some action. Affected file silc/local_command.[ch].
4102 * Changed channel_message and private_message client operations
4103 to deliver the message flags to the application. Added also
4104 the `flags' arguments to the silc_client_send_channel_message
4105 and silc_client_send_private_message functions. Affected file
4108 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4110 * Redefined the Private Message Payload to support private message
4111 keys and to support the new private message flags. Updated
4112 the protocol specs. Flags makes it possible to have for example
4113 CTCP style messages.
4115 * Added new type SilcPrivateMessagePayload and defined an API
4116 for it in the lib/silcclient/silcprivate.[ch].
4118 * Tested private message private keys successfully. Tested the
4119 private message key set, unset and list commands with the new
4122 * Redefined the Channel Message Payload to include the channel
4123 message flags (equal with private message flags) to support
4124 for example CTCP style messages.
4126 * Defined some of the message (for channel and private message)
4127 flags. Updated the protocol specs and added the flags to the
4128 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4130 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4132 * Added SilcKeyAgreementStatus type to the key agreement routines
4133 to indicate the current status and error if one occured.
4134 The status types are defined in the lib/silcclient/silcapi.h.
4136 * Added new local command KEY that is used to set and unset private
4137 keys for channels, set and unset private keys for private messages
4138 with remote clients and to send key agreement requests and
4139 negotiate the key agreement protocol with remote client. The
4140 key agreement is supported only to negotiate private message keys,
4141 it currently cannot be used to negotiate private keys for channels,
4142 as it is not convenient for that purpose.
4144 * Fixed a minor pending callback setting bug in the function
4145 silc_client_get_client_by_id_resolve, now the function works.
4146 Affected file lib/silcclient/idlist.c.
4148 * Added function silc_net_get_local_port to get local bound
4149 port by socket. Added to lib/silcutil/silcnet.[ch].
4151 * Added `sockets' and `sockets_count' fields to the SilcClient
4152 object. They hold the sockets of the listenning sockets in
4153 the client. Listenning sockets may be for example the key
4154 agreement server. Affected file lib/silcclient/client.[ch].
4155 Added functions the silc_client_add_socket and the
4156 silc_client_del_socket. They are exported to the application
4159 * Added ~./silc/clientkeys to support other client's public keys.
4161 * Renamed verify_server_key client operation to verify_public_key
4162 and added one argument to indicate the type of the connection
4163 (server, client etc.).
4165 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4167 * Added silc_server_connection_auth_request to handle the
4168 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4169 silcd/packet_receive.[ch].
4171 * Added silc_server_send_connection_auth_request into the
4172 silcd/packet_send.c to send the connection auth request packet.
4174 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4177 * Fixed the public key authentication in responder side in the
4178 server. The `auth_data' pointer includes the SilcPublicKey
4179 not the path to the public key. Affected file silcd/protocol.c.
4181 * Implemented the public key authentication in the initiator side
4182 in the server. Affected file silcd/protocol.c.
4184 * Removed the [RedirectClient] config section from the server
4185 configuration. Is not needed and I don't want to implement it.
4187 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Cleaned up the CMODE command in the server. It now works
4190 correctly and supports all the modes defined in the protocol.
4191 Affected file is silcd/command.c.
4193 * Added `hmac_name' field to the SilcChannelEntry in the server
4194 to hold the default HMAC of the channel. It can be set when
4195 creating the channel (with JOIN command). Affected files
4198 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4199 type to indicate the change of the current cipher and hmac
4200 on the channel. Client can safely ignore the <cipher> argument
4201 (if it chooses to do so) since the CHANNEL_KEY packet will
4202 force the channel key change anyway. The <hmac> argument is
4203 important since the client is responsible of setting the new
4204 HMAC and the hmac key into use.
4206 * Fixed the CMODE command in the client library as well.
4208 * Tested CMODE command in router environment successfully.
4210 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4212 * Show the version of the remote client (or server) when connecting
4213 to the server. It is logged to the log file. Affected file
4214 is silcd/protocol.c.
4216 * Fixed the KILLED notify handling in the client library. The
4217 client must be removed from all channels when receiving the
4220 Also, do not remove the client entry when giving the KILL
4221 command but when the KILLED notify is received.
4223 * Removed silc_idlist_find_client_by_nickname from the server.
4224 Not needed anymore. Affected files silcd/idlist.[ch].
4226 * Implemented the CHANNEL_CHANGE notify type handling to the
4227 server. Affected file silcd/server.c.
4231 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4233 * Added silc_server_send_notify_invite to send the INVITE
4234 notify between routers.
4236 * Implemented the INVITE command correctly to the server.
4238 * Implemented the INVITE notify type handling in the server.
4240 * Implemented the INVITE command to the client library and on the
4243 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Added function silc_server_get_client_resolve to find the
4246 client entry by ID from all ID lists and then resolve it
4247 (using WHOIS) if it cannot be found. Affected file is
4250 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4252 * Implemented the BAN command to the client library.
4254 * The JOIN command in the server now checks the invite list
4257 * Changed the silc_command_reply_payload_encode_va and the
4258 silc_command_payload_encode_va to support that if argument is
4259 NULL it ignores and checks the next argument. Affected file
4260 lib/silccore/silccommand.c.
4262 * Added silc_server_send_notify_ban to send the BAN notify
4263 type between routers.
4265 * Chaned the silc_notify_payload_encode to support that if
4266 argument is NULL it ignores and checks the next argument.
4267 Affected file lib/silccore/silcnotify.c.
4269 * Tested ban lists in router environment successfully.
4271 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4273 * Implemented BAN command to the server, in silcd/command.[ch].
4275 * Removed the BAN and INVITE_LIST modes from the CMODE command
4278 * Added function silc_string_match to regex match two strings.
4279 Affected files lib/silcutil/silcutil.[ch].
4281 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4283 * Redefined parts of the SilcChannelEntry in the server to support
4284 the new ban and invite lists.
4286 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4288 * Redefined the INVITE command. The same command can be used to
4289 invite individuals to the channel but also to manage the invite
4290 list of the channel (to add to and remove from the invite list).
4291 Updated the protocol specs.
4293 * Added new command SILC_COMMAND_BAN that can be used to manage
4294 the ban list of the channel. Updated the protocol specs.
4296 * Removed the channel modes: the SILC_CMODE_BAN and the
4297 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4298 in the CMODE command. The equivalent features are now available
4299 using INVITE and BAN commands. Updated the protocol specs.
4301 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4302 in the network about change in the current ban list. The notify
4303 type is not used by the client.
4305 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4306 support the invite lists.
4308 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4310 * Added new function silc_string_regexify that converts string
4311 including wildcard characters into regex string that can
4312 be used by the GNU regex library. Added into the file
4313 lib/silcutil/silcutil.[ch].
4315 Added silc_string_regex_combine to combine to regex strings
4316 into one so that they can be used as one regex string by
4317 the GNU regex library. Added into the file
4318 lib/silcutil/silcutil.[ch].
4320 Added silc_string_regex_match to match two strings. It returns
4321 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4323 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Imported GNU regex to the soruce tree into lib/contrib.
4326 Fixed some compiler warning from the regex.c.
4328 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Fixed MOTD command in the server to work in router environment.
4332 * Fixed the MOTD command in the client library to support
4333 the server argument in the command.
4335 * Added `nickname_len' argument to the silc_idlist_add_client
4336 in the server, as the `nickname' argument may be binary data
4339 * Added silc_idlist_get_channels to return all channels from
4342 * Implemented LIST command to the server. Affected file is
4345 * Implemented the LIST command to the client library and on the
4348 * Added [<user count>] argument to the LIST command reply.
4349 With private channels the user count is not shown.
4351 * Updated TODO and README.
4353 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4355 * The client entry's data.registered must be TRUE even with
4356 global client entry on global client list. The data.registered
4357 is used to check whether the client is anymore in the network,
4358 for example with WHOWAS command so it must be valid.
4360 * Fixed the WHOWAS command in the server. It now actually works
4361 in router environment. Added function into silcd/command_reply.c
4362 silc_server_command_reply_whowas_save.
4364 * Added silc_idlist_purge function to the silcd/idlist.c
4365 to periodically purge the ID Cache.
4367 * Fixed INFO command in the server. It works now in router
4368 environment. Added <server name> argument to the INFO command
4369 reply. Updated the protocol specs.
4371 * Fixed minor bug in silc_idcache_purge to not purge if the
4372 expire value is zero.
4374 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4375 they were buggy because of the WHOWAS information.
4377 * Fixed local command MSG to handle the async resolving of
4378 the remote client properly. It used to fail the first MSG.
4379 Affected file silc/local_command.c.
4381 * Added `data_len' field to SilcIDCache context.
4383 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4385 * Update TODO. Todo in commands in the server.
4387 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4389 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4390 used by routers as broadcast packet to inform other routers
4391 about the changed user mode.
4393 Implemented the notify handling in the server. Affected file is
4394 silcd/packet_receive.c. Added the function
4395 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4397 * Added new generic Channel Payload and deprecated the New Channel
4398 Payload. The New Channel Payload is now the generic Channel
4401 * Added new argument `mode' to the silc_server_send_new_channel
4402 as it is required in the Channel Payload now.
4404 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4405 and created a new and real SilChannelPayload to represent the
4406 new generic Channel Payload. Implemented the encode/decode
4407 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4409 * Added silc_server_get_client_channel_list to return the list
4410 of channels the client has joined for WHOIS command reply.
4411 Affected file silcd/server.[ch].
4413 * Implemented the channel list sending in the WHOIS command reply
4414 in server and in the client.
4416 Implemented the channel list displaying on the user interface
4417 as well. Affected file silc/client_ops.c.
4419 * Added silc_channel_payload_parse_list to parse list of Channel
4420 Payloads. It returns SilcDList list of SilcChannelPayloads.
4421 Client for example can use this function to parse the list of
4422 channels it receives in the WHOIS command reply. The caller
4423 must free the list by calling silc_channel_payload_list_free.
4424 Affected files lib/silccore/silcchannel.[ch].
4426 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4428 * Added one new argument <user mode> to the WHOIS command reply
4429 to return the mode of the user in SILC. Updated the protocol
4432 Implemented it to the server and client.
4434 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4436 * Fixed the mode printing on the user interface on joining.
4437 Affected file silc/client_ops.c.
4439 * Implemented the UMODE command and user modes in general to the
4440 client library and to the user interface.
4442 * Implemented the UMODE command to the server.
4444 * The server now sends UNKNOWN_COMMAND error status if client sends
4445 unknown command. Affected file silcd/command.c.
4447 * All server commands now handle the command identifier the right
4448 way when sending the command reply to the client. The client can
4449 use to identify the command replies with the identifier.
4451 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4453 * Added silc_server_get_client_route to resolve the route to
4454 the client indicated by the client ID. Affected file is
4457 * Added silc_server_relay_packet as general function to relay
4458 packet to arbitrary destination. This deprecates functions
4459 like _send_private_message_key, _relay_notify etc. Affected
4460 file is silcd/packet_send.[ch].
4462 Removed silc_server_send_key_agreement,
4463 silc_server_send_private_message_key and
4464 silc_server_packet_relay_notify functions from the file
4465 silcd/packet_send.[ch].
4469 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4470 server. Affected file silcd/packet_receive.[ch].
4472 * Implemented the KILL command to the client. Implemented the
4473 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4474 Affected files lib/silcclient/command[_reply].c and
4475 lib/silcclient/client_notify.c. Implemented the KILL notify
4476 printing in the user inteface.
4478 * Fixed a lot silc_parse_nick memory leaks from the client
4479 library in the file lib/silcclient/command.c.
4481 * Changed the silc_server_send_notify_on_channels's `sender'
4482 argument from SilcSocketConnection to SilcClientEntry to
4483 check the sender as entry and not as connection object and not
4484 to send to the client provided as argument. The affected file
4485 is silcd/packet_send.[ch].
4487 * The notify packets that are destined directly to the client used
4488 to not to be processed by the server. Now changed that and the
4489 server processes all notify packets. After relaying the packet
4490 to the client the notify packet is processed in the server.
4492 * The silc_server_free_client_data now checks whether there is
4493 pending outgoing traffic for the client and purges the data to
4494 the network before removing the client entry.
4496 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4499 an client is killed from the SILC Network. Updated the protocol
4502 Added new function silc_server_send_notify_killed to the
4503 silcd/packet_send.[ch].
4505 * Added function silc_server_packet_relay_notify to relay notify
4506 packets that are destined directly to a client. In this case
4507 the server does not process the notify packets but merely relays
4508 it to the client. Affected file silcd/packet_send.[ch].
4510 Added also silc_server_packet_process_relay_notify to check
4511 whereto relay the notify. Affected file is
4512 silcd/packet_receive.[ch].
4514 * Implemented the KILL command to the server.
4518 * Added the backup schema desgined last fall to the protocol
4519 specs for everyone to see. The specification is in the
4520 *-spec-xx.txt draft and the packet type definitions for the
4521 backup routers is in *-pp-xx.txt draft. Thusly, added also
4522 new packet type SILC_PACKET_CELL_ROUTERS.
4524 * A big security problem in the implementation discovered. The
4525 signoff of an client did not cause new channel key generation
4526 which it of course should've done. The channel keys must be
4527 always re-generated when client leaves (or signoffs) the channel.
4528 The silc_server_remove_from_channels funtion now handles
4529 the channel key re-generation.
4531 * Added `sender' argument to the silc_server_send_notify_on_channels
4532 to not to send the client provided as argument. Affected file
4533 silcd/packet_send.[ch].
4535 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4537 * Implemented OPER and SILCOPER commands into the server and
4540 * Added silc_auth_verify and silc_auth_verify_data to verify
4541 the authentication directly from the authentication payload.
4542 It supports verifying both passphrase and public key based
4543 authentication. Affected file lib/silccore/silcauth.[ch].
4545 * Added `hash' field to the SilcIDListData structure. It is the
4546 hash negotiated in the SKE protocol. Affected file is
4549 * Slight redesigning of the SilcAuthPayload handling routines.
4550 Do not send SilcPKCS but SilcPublicKey as argument.
4552 * Implemented the public key authentication support to the
4553 serverconfig. The public key is loaded from the provided path
4554 and saved as authentication data to void * pointer. Thus,
4555 changed the unsigned char *auth_data to void *auth_data;
4557 * Fixed SHUTDOWN command to send the reply before the server
4558 is shutdown. :) Affected file silcd/command.c.
4560 * Fixed fatal bug in CONNECT command. The hostname was invalid
4561 memory and server crashed. Affected file silcd/command.c.
4563 * Fixed fatal bug in CLOSE command. The server_entry became
4564 invalid but was referenced later in the command. Affected file
4567 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4569 * Fixed fatal bug in failure packet handling. Server ignored
4570 the failure and thus crashed when it came.
4574 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4576 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4577 that the command may be executed only once in (about) 2 seconds.
4578 The old SILC_CF_LAG flag is same but allows command bursts up
4579 to five before limiting.
4581 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4582 server code. Various commands now includes the CF_LAG_STRICT
4583 flag to disallow any kind of miss-use of the command.
4585 * Fixed the silc_buffer_unformat to not to allocate any data
4586 if the length of the data is zero. It used to allocate the
4587 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4589 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4591 * Changed the format of AdminConnection configuration section
4592 in the server. Added username of the admin to the format.
4593 Affected files silcd/serverconfig.[ch].
4595 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4596 to return admin configuration data by host, username and/or
4599 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4601 * Implemented WHOWAS command to the server. Added the functions:
4603 silc_server_command_whowas_parse,
4604 silc_server_command_whowas_send_reply,
4605 silc_server_command_whowas_from_client and
4606 silc_server_command_whowas_from_server
4608 * Added <Client ID> argument to the WHOWAS command reply. Updated
4609 the protocol specs accordingly.
4611 * Implemented WHOWAS command and command_reply to the client
4614 Implemented the WHOWAS printing on the user interface.
4616 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Added new argument to the WHOWAS command reply, the real name.
4619 It is an optional argument. Updated the protocol specs.
4621 * Added SilcIDCacheDestructor callback that is registered when
4622 the SilcIDCache is allocated. The callback is called when
4623 an cache entry in the ID Cache expires, or is purged from the
4624 cache. Added into lib/silccore/idcache.[ch].
4626 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4627 to destruct the client entries when the cache entry expires.
4628 Other ID Cache's in server and in the client library ignores
4631 * If the ID Cache entry's `expire' field is zero then the entry
4632 never expires. Added boolean `expire' argument to the
4633 silc_idcache_add function in the lib/silccore/idcache.[ch].
4634 If it is TRUE the default expiry value is used.
4636 * Added silc_server_free_client_data_timeout that is registered
4637 when client disconnects. By default for 5 minutes we preserve
4638 the client entry for history - for WHOWAS command.
4640 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * Added support to the server to enforce that commands are not
4643 executed more than once in 2 seconds. If server receives
4644 commands from client more frequently, timeout is registered
4645 to process the commands. Affected file silcd/command.c.
4646 Added new function silc_server_command_process_timeout.
4648 * Changed NICK_NOTIFY handling in client library to check that
4649 if the client's nickname was changed, so there is no need to
4650 resolve anything from the server.
4652 * Removed error printing from the WHOIS and IDENTIFY commands.
4653 If error occurs then it is ignored silently in the client library.
4654 The application, however, may map the received error to
4655 human readable error string. The application currently maps
4656 the NO_SUCH_NICKNAME error to string.
4658 * Made the command status message public to the application. Moved
4659 them from lib/silcclient/command_reply.c to
4660 lib/silcclient/command_reply.h. The application can map the
4661 received command status to the string with the
4662 silc_client_command_status_message function.
4664 * Added check to the server to check that client's ID is same
4665 as the Source ID in the packet the client sent. They must
4668 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4670 * Added dist-bzip hook to the Makefile.am to make bzip2
4671 compressed distributions.
4673 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4675 * Server now enforces the maximum length for the nickname and
4676 the channel as protocol specification dictates. 128 bytes for
4677 nickname and 256 bytes for channel name.
4679 * Moved the WHOIS printing to the application. The client libary
4680 does not print out the WHOIS information anymore, the application
4681 must do it. Renamed silc_client_command_reply_whois_print to
4682 the silc_client_command_reply_whois_save.
4684 The client's idle time is also sent to the application now, and
4685 the idle is shown on screen.
4687 * Added silc_client_command_reply_identify_save to save the
4688 received IDENTIFY entries.
4690 * Do not check for channel private keys in message sending and
4691 reception if the channel does not have the PRIVKEY mode set.
4692 Affected file lib/silclient/client_channel.c.
4694 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4696 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4697 just surfaced after chaning the JOIN procedure.
4699 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4701 * Added silc_client_get_clients_by_list to get client entries
4702 from Client ID list, that is returned for example by JOIN
4703 and USERS command replies. The application should use this
4704 function for example when JOIN command reply is received to
4705 resolve the clients already on the channel (library does not
4706 do that anymore as USERS command reply is not used in the JOIN
4707 procedure anymore). Affected files lib/silcclient/silcapi.h and
4708 lib/silcclient/idlist.c.
4710 * JOIN command reply and USERS command reply returns now SilcBuffer
4711 pointers instead of unsigned char pointers when returning
4712 the client list and mode list.
4714 * Added <Client ID> argument to the JOIN command reply, mainly
4715 for the server to identify for which client the command was
4716 originally sent. Updated protocol specs accordingly.
4718 * Added SilcDlist private_key pointer to the SilcChannelEntry
4719 in the client to support the channel private keys. Affected
4720 file is lib/silcclient/idlist.h.
4722 * Added SilcChannelPrivateKey argument to the function
4723 silc_client_send_channel_message so that application can choose
4724 to use specific private ke if it wants to. If it is not provided,
4725 the normal channel key is used, unless private keys are set.
4726 In this case the first (key that was added first) is used
4727 as the encryption key.
4729 * Implemented the support for channel private key handling.
4730 Implemented the following functions:
4732 silc_client_add_channel_private_key,
4733 silc_client_del_channel_private_keys,
4734 silc_client_del_channel_private_key,
4735 silc_client_list_channel_private_keys and
4736 silc_client_free_channel_private_keys
4738 Affected file lib/silcclient/client_channel.c.
4740 * Added the support for the private keys in the channel message
4741 sending and encryption and in the message reception and
4742 decryption. Affected funtions are
4743 silc_client_send_channel_message and silc_client_channel_message.
4745 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4747 * Added SKE's key verify callback to the client library's
4748 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4750 * Removed the statement that server (or router) must send USERS
4751 command reply when joining to the channel so that the client
4752 knows who are on the channel. Instead, the client list and
4753 client's mode list is now sent in the JOIN command reply to the
4754 client who joined channel. This is better solution.
4756 * Added function silc_server_get_users_on_channel and function
4757 silc_server_save_users_on_channel to the silcd/server.[ch].
4759 * Removed function silc_server_command_send_users from the
4762 * Do not show topic on the client library anymore. The topic is
4763 sent in the command reply notify to the application and the
4764 application must show the topic now.
4766 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4768 * Added client searching by nickname hash into the IDENTIFY and
4769 WHOIS commands in the server as they were clearly missing from
4770 them. Affected file is silcd/command.c.
4772 * Fixed a bug in private message receiving in the client library.
4773 The remote ID was freed and it wasn't supposed, now it is
4776 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4778 * Minor fix to the channel payload; allocate the data area, as it
4779 needs to be of specific length.
4781 * If the key agreement port is zero then the operating
4782 system will define the bound port. Affected files are
4783 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4785 * Added new function silc_channel_payload_decrypt into the file
4786 lib/silccore/silcchannel.[ch].
4788 * Moved the channel message etc, check from silc_packet_decrypt
4789 to applications. The library calls now a generic
4790 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4791 when the packet is either normal or special. This was done to
4792 allow more wide range of checking that was not allowed when
4793 the code was in library. Now applications can do virtually any
4794 checks to the packet and return to the library the decision how
4795 the packet should be processed. Affected files are
4796 lib/silccore/silcpacket.[ch].
4798 Added silc_server_packet_decrypt_check to the server and
4799 silc_client_packet_decrypt_check to the client library.
4801 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4802 to send with specified source and destination information.
4804 * Channel message delivery between routers was broken after the
4805 channel key distribution was fixed earlier. The channel key
4806 was used be to distributed to other routers as well which is not
4807 allowed by the protocol. Now this is fixed and channel keys
4808 really are cell specific and the channel message delivery between
4809 routers comply with the protocol specification.
4811 * Fixed various commands in server to check also the global list
4812 for the channel entry and not just the local list. The affected
4813 file silcd/command.c.
4815 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4817 * Added assert()s to buffer formatting and unformatting routines
4818 to assert (if --enable-debug) when error occurs. Affected
4819 file: lib/silcutil/silcbuffmt.c.
4821 * Changed to auto-reconnect to check whether the remote host is
4822 router and register the re-connect timeout if it is. It used
4823 to check that whether we are normal server, but router must do
4824 auto-reconnect with another router as well. Affected file
4827 * Removed the [<key len>] option from CMODE command as the cipher
4828 name decides the key length, nowadays. See the defined ciphers
4829 from the protocol specification.
4831 * Added [<hmac>] option to the CMODE command to define the HMAC
4832 for the channel. Added SILC_CMODE_HMAC channel mode.
4834 * Added [<hmac>] option for the JOIN command so that user can
4835 select which HMAC is used to compute the MACs of the channel
4838 * Added Hmac field to the Channel Message Payload. The integrity
4839 of plaintext channel messages are now protected by computing
4840 MAC of the message and attaching the MAC to the payload. The
4841 MAC is encrypted. Now, it is clear that this causes some
4842 overhead to the size of the packet but rationale for this is that
4843 now the receiver can verify whether the channel message decrypted
4844 correctly and also when private keys are set for the channel the
4845 receiver can decrypt the packet with several keys and check from
4846 the MAC which key decrypted the message correctly.
4848 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4849 lib/silccrypt/silccipher.[ch].
4851 * Added silc_hash_len to return the digest length into the
4852 lib/silcrypt/silchash.[ch].
4854 * Rewrote parts of Silc Channel Payload interface in the
4855 lib/silccore/silcchannel.[ch]. The encode function now also
4856 encrypts the packet and parse function decrypts it.
4858 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4860 * Fixed a minor formatting bug in the SKE's key material processing.
4861 It actually might have processed the keys wrong way resulting
4864 * Redefined the mandatory HMAC algorithms and added new algorithms.
4865 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4866 and hmac-md5 truncated to 96 bits. The mandatory is now
4867 hmac-sha1-96. Rest are optional (including the one that used
4868 to be mandatory). Rationale for this is that the truncated HMAC
4869 length is sufficient from security point of view and can actually
4870 make the attack against the HMAC harder. Also, the truncated
4871 HMAC causes less overhead to the packets. See the RFC2104 for
4874 * Added new [hmac] configuration section. The SKE used to use
4875 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4876 is of course wrong. The official names that must be proposed in
4877 the SKE are the ones defined in the protocol specification
4878 (hmac-sha1-96 for example). The user can configure any hmac
4879 using any hash function configured in the [hash] section. At
4880 least, the mandatory must be configured.
4882 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4884 * Added HMAC list to the SKE proposal list. It has now both
4885 hash algorithm list and HMAC list. This makes the protocol
4886 incompatible with previous versions. The SKE now seems to work
4887 the way it is supposed to work, for the first time actually.
4889 * Defined plain Hash algorithms to the protocol specification.
4892 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4894 * Implemented support for key agreement packets into the server.
4895 Added functions silc_server_key_agreement and
4896 silc_server_send_key_agreement. Other than these functions,
4897 server has nothing to do with this packet.
4899 * Added support for private message key packets into the server.
4900 Added functions silc_server_private_message_key and
4901 silc_server_send_private_message_key.
4905 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4906 called in the protocol's final callback instead in the END
4907 protocol state. This makes a little more sense and in the same
4908 time in client we can use the same protocol routines for normal
4909 key exchange and to key agreement packet handling as well.
4911 * Added to both client's and server's KE protocol context the
4912 SilcSKEKeyMaterial pointer to save the key material. We will
4913 bring the key material to the protocol's final callback by doing
4914 this. The final callback must free the key material.
4916 * Added SKE's packet_send callback into client's KE protocol
4917 context so that the caller can choose what packet sending function
4918 is used. This way we can use different packet sending when
4919 doing normal SKE when doing key agreement packet handling (in
4920 the key agreement packet handling we do not want to encrypt
4923 * Implemented the responder side of the key agreement routines
4924 in the client. The client can now bind to specified port and
4925 accept incoming key negotiation. The key material is passed
4926 to the application after the protocol is over.
4928 * Implemented the processing of incoming Key Agreement packet
4929 in the client. Added function silc_client_key_agreement to
4932 * Implemented the intiator side of the key agreement routines
4933 in the client. The client can now initiate key agreement with
4934 another remote client. The key material is passed to the
4935 application after the protocol is over.
4937 * Created client_keyagr.c to include all the key agreement
4940 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4941 SILC_TASK_CALLBACK except that it is not static.
4943 * Created client_notify.c and moved the Notify packet handling
4944 from the client.[ch] into that file.
4946 * Created client_prvmsg.c and moved all private message and
4947 private message key routines from the client.[ch] into that file.
4949 * Create client_channel.c and moved all channel message and
4950 channel private key routines from the client.[ch] into that file.
4952 * Changed silc_client_get_client_by_id_resolve to resolve with
4953 WHOIS command instead of IDENTIFY command, in the file
4954 lib/silclient/idlist.c.
4956 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4958 * Implemented the SKE's responder side to the Client library.
4960 * When FAILURE is received to the protocol do not trust it
4961 blindly. Register a timeout to wait whether the remote closes
4962 the connection as it should do it, only after that process the
4963 actual failure. This was changed to both client and server.
4965 * Added client_internal.h to include some of the structures
4966 there instead of client.h in lib/silcclient/.
4968 * Added function silc_task_unregister_by_callback to unregister
4969 timeouts by the callback function.
4971 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4973 * Some "Incomplete WHOIS info" errors has been appearing on the
4974 log files. Took away the entry->userinfo check from WHOIS
4975 reply sending. The entry->userinfo is now " " if client did not
4976 provide one. I thought this was fixed earlier but something
4977 is wrong still. Let's see if the error still appears.
4979 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4981 * Fixed a minor bug in the login when the channel key is
4982 re-generated in the server. It used to generate the key in
4983 wrong order and thus caused problems in the channel traffic.
4985 * Fixed a minor bug in channel key distsribution after
4986 KICK command. The key was not sent to the router even though
4989 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4991 * Added silc_ske_process_key_material_data as generic routine
4992 to process any key material as the SILC protocol dictates. The
4993 function is used by the actual SKE library but can be used by
4994 applications as well. This relates to the private message keys
4995 and the channel private keys since they must be processed the
4996 same way the normal SILC session keys. The protocol dictates
4997 this. Affected files: lib/silcske/silcske.[ch].
4999 Added also silc_ske_free_key_material to free the
5000 SilcSKEKeyMaterial structure.
5002 * Defined silc_cipher_set_key function to set the key for
5003 cipher without using the object's method function. The affected
5004 files: lib/silccrypt/silccipher.[ch].
5006 * Implemented silc silc_client_add_private_message_key,
5007 silc_client_add_private_message_key_ske,
5008 silc_client_del_private_message_key,
5009 silc_client_list_private_message_keys and
5010 silc_client_free_private_message_keys functions in the
5013 Added functions silc_client_send_private_message_key to send
5014 the Private Message Key payload and silc_client_private_message_key
5015 to handle incoming Private Message Key payload.
5017 * Added Cipher field to the Private Message Key payload to set
5018 the cipher to be used. If ignored, the default cipher defined
5019 in the SILC protocol (aes-256-cbc) is used.
5021 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5023 * Removed lib/silcclient/ops.h file.
5025 Redefined parts of the SILC Client Library API. Created new
5026 file silcapi.h that deprecates the ops.h file and defines the
5027 published Client Library API. Defined also private message key
5028 API and channel private key API into the file.
5030 This is the file that the application must include from the
5031 SILC Client Library. Other files need not be included by
5032 the application anymore.
5034 * Added new key_agreement client operation callback and also
5035 defined the Key Agreement library API for the application.
5037 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5039 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5040 is used by clients to request key negotiation between another
5041 client in the SILC network. If the negotiation is started it
5042 is performed using the SKE protocol. The result of the
5043 negotiation, the secret key material, can be used for example
5044 as private message key.
5046 Implemented the Key Agreement payload into the files
5047 lib/silccore/silauth.[ch].
5049 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Redefined ciphers for the SILC protocol. Added some new ciphers
5052 and defined the key lengths for the algorithms. Changed the
5053 code accordingly. The default key length is now 256 bits.
5055 * Fixed SKE key distribution function silc_ske_process_key_material
5056 when the key length is more than 128 bits. The default key
5057 length in SILC is now 256 bits.
5059 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5060 to indicate unsupported algorithm.
5062 * Renamed rijndael.c to aes.c and all functions as well.
5064 * Fixed a long standing channel key setting bug in client library.
5065 Weird that it has never surfaced before.
5067 * Fixed bug in channel deletion. If the entire channel is removed
5068 then it must also delete the references of the channel entry
5069 from the client's channel list as the client's channel entry and
5070 the channel's client entry share same memory.
5072 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5074 * Implemented CONNECT and SHUTDOWN commands in the client.
5076 * Implemented CLOSE command to the client.
5078 * Added the function silc_idlist_find_server_by_name into the
5079 files silcd/idlist.[ch].
5081 Added the function silc_idlist_find_server_by_conn into the
5082 files silcd/idlist.[ch].
5084 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5086 * DIE command was renamed to SHUTDOWN. Updated the both code
5089 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5090 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5092 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5095 * Added function silc_server_create_connection function to create
5096 connection to remote router. My server implementation actually
5097 does not allow router to connect to normal server (it expects
5098 that normal server always initiates the connection to the router)
5099 so the CONNECT command is only good for connecting to another
5102 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5104 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5105 or some other client was kicked from the channel.
5107 Implemented the handling of the notify type to both client
5110 Implemented silc_server_send_notify_kicked to send the KICKED
5111 notify. It is used to send it to the server's primary router.
5113 * Implemented the KICK command into server and client.
5115 * Added `query' argument to the silc_idlist_get_client function
5116 to indicate whether to query the client from server or not if
5119 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5120 to indicate that the client is not channel founder.
5124 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5126 * Removed the rng context from SilcPacketContext structure and
5127 changed that the packet routine uses the Global RNG API.
5129 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5131 * Added support for quit message that client can "leave" on the
5132 channel when it quits the SILC. It is ditributed inside the
5133 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5135 Added silc_server_free_client_data that will take the
5136 signoff message as argument.
5138 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5140 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Updated parts of the protocol specification to keep it up
5145 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5147 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5148 payloads in one packet.
5150 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5151 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5152 use now the new List flag.
5154 * Also deprecated the following packet types: REPLACE_ID,
5155 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5157 * Added list support for Notify packet in server.
5159 * Added silc_server_send_notify_channel_change to send the
5160 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5161 the silc_server_send_replace_id.
5163 * Added silc_server_send_notify_nick_change to send the
5164 NICK_CHANGE notify type. Deprecates the function
5165 silc_server_send_replace_id.
5167 * Added silc_server_send_notify_join to send the JOIN notify type.
5168 Deprecates the function silc_server_send_new_channel_user.
5170 * Added silc_server_send_notify_leave to send LEAVE notify type.
5171 Deprecates the function silc_server_send_remove_channel_user.
5173 * Added silc_server_send_notify_cmode and
5174 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5175 types. Deprecates the silc_server_send_set_mode function.
5177 * Added SERVER_SIGNOFF notify type to indicate that server has
5178 quit. This means that all clients on the channel from that
5179 server will drop. This can be also used when netsplit happens.
5181 Deprecated REMOVE_ID packet type since it is not needed anymore
5184 Added silc_server_send_notify_server_signoff to send the
5185 SERVER_SIGNOFF notify type. Deprecates the function
5186 silc_server_send_remove_id.
5188 Added also silc_server_send_notify_signoff to send the
5189 SIGNOFF notify type.
5191 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5192 SILC protocol from this day on. Changed the protocol
5193 specification as well.
5195 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5196 notify type. It is used between routers to notify about
5197 topic changes on a channel.
5199 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5202 * Partly updated the protocol specification to comply with the
5203 changes now made. It is still though a bit outdated.
5205 * The JOIN notify type now takes one extra argument <Channel ID>.
5206 The packet used to be destined to the channel but now the
5207 JOIN type may be sent as list thus it is impossible to
5208 destine it to any specific channel. By adding this argument
5209 it is again possible.
5211 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * Added CREDITS file. The CHANGES and CREDITS file will appear
5214 in the distribution as well.
5216 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5218 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5219 types in the server's silcd/packet_receive.c.
5221 * Implemented CMODE and CUMODE to work in router environment.
5223 * Fixed minor encoding and decoding buglet from the
5224 lib/silccore/silcmode.c.
5226 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5229 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5231 * Changed all SilcConfigServer* and silc_config_server* to
5232 SilcServerConfig* and silc_server_config*, respectively.
5235 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5237 * Associated the ID (client or server ID) to the Authentication
5238 Payload to avoid any possibility of forging. Updated the
5239 protocol specification and the code accordingly.
5241 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * The RSA key length is now save to the RsaKey context in the
5244 key generation process in lib/silccrypt/rsa.c. The key length
5245 is now used to figure out the maximum size of the block allowed
5246 to be encrypted/signed.
5248 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5249 is equivalent to the silc_mp_mp2bin but does not allocate any
5252 * Changed silc_mp_mp2bin API to take length argument. If it is
5253 non-zero then the buffer is allocated that large. If zero, then
5254 the size is approximated using silc_mp_sizeinbase, which however
5257 * Created Global RNG API which is global RNG that application can
5258 initialize. After initializing, any routine anywhere in the
5259 code (including library) can use RNG without allocating a new
5260 RNG object. This was done to allow this sort of use of the
5261 RNG in code that has no chance to allocate RNG object. All
5262 applications currently allocate this and many routines in the
5263 library use this. Affected file lib/silccrypt/silcrng.[ch].
5265 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5266 it to use the Global RNG API.
5268 * Defined Authentication Payload into protocol specification that
5269 is used during SILC session to authenticate entities. It is
5270 used for example by client to authenticate itself to the server
5271 to obtain server operator privileges.
5273 Implemented this payload into the lib/silccore/silcauth.[ch].
5274 Implemented also routines for public key based authentication
5275 as the new protocol specification dictates.
5277 Moved definitions of different authentication methods from
5278 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5280 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5281 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5282 silc_pkcs_verify_with_hash functions into the file
5283 lib/silccrypt/silcpkcs.[ch].
5285 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5287 * The client entry's userinfo pointer must be always valid.
5288 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5289 will fail since it requires the userinfo. Now, the userinfo
5290 is allocated as "" if actual userinfo does not exist. Actually,
5291 it must exist and it is totally Ok to drop client connections
5292 that does not announce the userinfo. However, we will make
5293 this workaround for now.
5295 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5296 to return the remote port by socket.
5298 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5300 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5301 SILC_SERVER_PENDING_EXEC and added an new macro
5302 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5303 data or when error occurs while processing the pending command.
5305 Added new argument `destructor' into silc_server_command_pending
5306 and to the SilcServerCommandPending object. This destructor is
5307 now called after calling the pending callback or if error occurs
5308 immediately. If error occurs the actual pending callback won't
5309 be called at all - only the destructor. The destructor may be
5310 NULL if destructor is not needed.
5312 All this applies for client library code as well. Similar
5313 changes were made there as well for the pending commands.
5315 In the client, the application must now allocate the
5316 SilcClientCommandContext with the silc_client_command_alloc
5319 * Added reference counter to the SilcServerCommandContext. Added
5320 function silc_server_command_alloc and silc_server_command_dup
5323 Same type of functions added to the client library for the same
5326 * Removed the cmd_ident from IDListData away since it is now
5327 global for all connections. It is the command identifier used
5328 in command sending and with pending commands. The affected file
5331 * Added reference counter to the SilcSocketConnection objecet to
5332 indicate the usage count of the object. The object won't be
5333 freed untill the reference counter hits zero. Currently only
5334 server uses this, and client ignores it. The client must be
5335 set to use this too later. The affected files are
5336 lib/silccore/silcsockconn.[ch]. Added also the function
5337 silc_socket_dup to increase the reference counter.
5339 This was mainly added because it is possible that the socket
5340 is removed underneath of pending command or other async
5341 operation. Now it won't be free'd and proper DISCONNECTING
5342 flags, etc. can be set to avoid sending data to connection that
5343 is not valid anymore.
5345 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5346 the connection. After that it sets SILC_SET_DISCONNECTED.
5347 It is, however, possible that the socket data is not still freed.
5348 The silc_server_packet_process now checks that data is not
5349 read or written to connection that is DISCONNECTED. The socket
5350 get's freed when the reference counter hits zero.
5352 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5354 * Changed the client operation API: channel_message operation's
5355 `sender' is now the client entry of the sender, not the nickname
5356 and the `channel' is the channel entry, not the channel name.
5358 In the private_message operation the `sender' is now also the
5359 client entry of the sender not the nickname.
5361 Affected file is lib/silcclient/ops.h and all applications
5362 using the client operations.
5364 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5366 * Moved the calling of ops->connect() from connect_to_server_final
5367 into receive_new_id functin since that is the point when the
5368 client is actually allowed to send traffic to network. The
5369 affected file is lib/silcclient/client.c.
5371 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5373 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5374 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5375 (if needs broadcasting) instead of broadcasting the packets one
5376 by one which would make a burst in the network traffic.
5378 * Added `broadcast' argument to the functions in silcd/server.[ch]
5379 silc_server_create_new_channel[_with_id] to indicate whether
5380 to send New Channel packet to primary router.
5382 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5384 * Added new function into the silcd/server.[ch] files:
5385 silc_server_create_new_channel_with_id to create new channel with
5386 already existing Channel ID.
5388 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5389 lib/silccore/silcpacket.h. This packet is used t send list of
5390 Set Mode payloads inside one packet. Server uses this to set
5391 the modes for the channels and clients on those channels, that it
5392 announced to the router when it connected to it. The protocol
5393 specification has been updated accordingly.
5395 * The silc_server_new_channel did not handle the packet coming
5396 from normal server as it normally does not send that. However,
5397 when it announces its channels it does send it. Implemented
5398 the support for that.
5400 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5401 into the file lib/silccore/id.h.
5403 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5405 * Fixed memory leaks in the functions silc_idlist_del_client,
5406 silc_idlist_del_channel and silc_idlist_del_server in the file
5407 silcd/idlist.c. All of those leaked like a sieve.
5409 * Fixed some small memory leaks in the client's function
5410 silc_client_notify_by_server.
5412 * Added functions into silcd/server.c: silc_server_announce_clients,
5413 silc_server_announce_channels and silc_server_announce_server.
5414 These functions are used by normal and router server to announce
5415 to its primary router about clients, channels and servers (when
5416 router) that we own. This is done after we've connected to the
5419 These functions effectively implements the following packet types:
5420 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5421 and SILC_PACKET_NEW_ID_LIST.
5423 * Added new functions into the silcd/packet_receive.[ch]:
5424 silc_server_new_id_list, silc_server_new_channel_list and
5425 silc_server_new_channel_user_list to handle the incoming
5426 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5428 * Added support of changing Channel ID in the function
5429 silc_server_replace_id. If the server that announces a channel
5430 to the router already exists in the router (with same name but
5431 with different Channel ID), router is responsible to send
5432 Replace ID packet to the server and force the server to change
5433 the Channel ID to the one router has.
5435 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5436 client that the Channel ID has been changed by the router. The
5437 normal server sends this to the client. Client must start using
5438 the new Channel ID as the channel's ID.
5440 Implemented handling of this new type into lib/silcclient/client.c
5441 into the function silc_client_notify_by_server.
5443 * Added new function silc_idlist_replace_channel_id into the files
5444 silcd/idlist.[ch] to replace the Channel ID.
5446 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5448 * Call silc_server_command_identify_check always when processing
5449 the IDENTIFY command in silcd/command.c
5451 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5453 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5454 send keepalive packets. The packet can be sent by clients,
5455 servers and routers.
5457 Added function silc_socket_set_heartbeat into the file
5458 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5459 If not set, the heartbeat is not performed. The actual
5460 heartbeat is implemented in the low level socket connection
5461 library. However, application is responsible of actually
5464 Added silc_server_send_heartbeat to send the actual heartbeat
5465 packet into silcd/packet_send.[ch]. Server now performs
5466 keepalive with all connections.
5468 * Added silc_task_get_first function into lib/silcutil/silctask.c
5469 to return the timeout task with shortest timeout. There was a bug
5470 in task unregistration that caused problems. TODO has been
5471 updated to include that task system must be rewritten.
5473 * The client library will now resolve the client information when
5474 receiving JOIN notify from server for client that we know but
5475 have incomplete information.
5477 * Rewrote parts of silc_server_remove_from_channels and
5478 silc_server_remove_from_one_channel as they did not remove the
5479 channel in some circumstances even though they should've.
5481 * Encryption problem encountered in server:
5483 The LEAVE command used to send the Channel Key packet to the
5484 router immediately after generating it. However, the code
5485 had earlier sent Remove Channel user packet but not immediately,
5486 ie. it was put to queue. The order of packets in the router
5487 was that Channel Key packet was first and Remove Channel User
5488 packet was second, even though they were encrypted in the
5489 reverse order. For this reason, MAC check failed. Now, this
5490 is fixed by not sending the Channel Key packet immediately but
5491 putting it to queue. However, this is more fundamental problem:
5492 packets that are in queue should actually not be encrypted
5493 because packets that are sent immediately gets encrypted
5494 actually with wrong IV (and thus MAC check fails). So, packets
5495 that are in queue should be encrypted when they are sent to
5496 the wire and not when they put to the queue.
5498 However, the problem is that the current system has not been
5499 designed to work that way. Instead, the packet is encrypted
5500 as soon as possible and left to the queue. The queue is then
5501 just purged into wire. There won't be any fixes for this
5502 any time soon. So, the current semantic for packet sending
5505 o If you send packet to remote host and do not force the send
5506 (the packet will be in queue) then all subsequent packets to the
5507 same remote host must also be put to the queue. Only after the
5508 queue has been purged is it safe again to force the packet
5511 o If you send all packets immediately then it safe to send
5512 any of subsequent packets through the queue, however, after
5513 the first packet is put to queue then any subsequent packets
5514 must also be put to the queue.
5516 Follow these rules and everything works fine.
5518 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5520 * Added new function silc_server_remove_clients_by_server to
5521 remove all client entries from ID list when the server connection
5522 is lost. In this case it is also important to invalidate all
5523 client entires as they hold the invalid server entry. This
5524 fixes fatal bug when server has lost connection and will reconnect
5527 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5529 * Made some sanity checks to silc_server_daemonise like to check
5530 whether the requested user and group actually exists.
5532 * Added sanity check to SKE's silc_ske_responder_finish to check
5533 that the public and private key actually is valid.
5535 * Invalidate the client's nickname when receiving Replace ID
5536 packet and the Client ID is being replaced. This means that the
5537 server will query the nickname if someone needs it (client)
5540 * Sort the ID Cache in client library when the ID Cache data
5541 has changed (needs sorting).
5543 * Do not allow for SILC client to create several connections to
5544 several servers. The client does not support windows right now
5545 and generating multiple connections causes weird behaviour.
5547 Irssi-silc client does support windows and can handle several
5548 connections without problems, see: www.irssi.org and SILC plugin.
5550 * Fixed some places where client was added to the IDList. The
5551 rule of thumb is following (in order to get everything right):
5552 If the client is directly connected local client then the
5553 `connection' argument must be set and `router' argument must be
5554 NULL to silc_idlist_add_client function. If the client is not
5555 directly connected client then the `router' argument must
5556 bet set and the `connection' argument must be NULL to the
5557 silc_idlist_add_client function.
5559 * The funtion silc_server_packet_send_local_channel actually did
5560 not check whether the client was locally connected or not. It
5561 does that now. Fixed a bug related to LEAVE command.
5563 * Fixed Remove Channel User payload parsing bug in server's
5564 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5566 * The server's silc_server_save_channel_key now checks also the
5567 global ID list for the channel as it might not be in the local
5568 list. Fixed a bug related to LEAVE command.
5570 * Is this the end of the [<unknown>] buglet that has been lurking
5571 around for a long time? A little for loop fix in server's
5572 silc_server_command_whois_parse that is used by both IDENTIFY
5573 and WHOIS command. At least, this was a clear bug and a cause
5574 of one type of [<unknown>] buglet.
5576 * WHOIS and IDENTIFY commands call the function
5577 silc_server_command_[whois/identify]_check function even if
5578 we are not router server.
5580 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5582 * Added --with-gmp configuration option. If set the GMP
5583 is always compiled in the SILC source tree. If not set then
5584 it is checked whether the system has the GMP3 installed. If
5585 it has then the GMP won't be compiled (the system's headers
5586 and library is used), if it doesn't have it then the GMP is
5587 compiled in the SILC source tree.
5589 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5591 * Changed RSA private exponent generation to what PKCS #1
5592 suggests. We try to find the smallest possible d by doing
5593 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5594 not security fix but optimization.
5596 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Added new config entry [Identity] to fork the server and run
5599 it as specific user and group. A patch from Bostik.
5601 * Imported Dotconf configuration library into lib/dotconf.
5602 This will be used to create the SILC configuration files later.
5603 It will appear in the distsribution after this commit.
5605 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5607 * A big code auditing weekend happening. Auditing code for
5608 obvious mistakes, bugs and errors. Also, removing any code
5611 Removed files for being obsolete:
5613 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5614 inline in the file lib/silcutil/silcbuffer.h)
5616 o lib/silcutil/silcbufutil.c (the header has inline versions)
5618 Changed code to fix possible error conditions:
5620 o The buffer formatting routines now check that the destination
5621 buffer really has enough space to add the data. This applies for
5622 both buffer formatting and unformatting
5623 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5624 unformatting was changed to accomodate following rules:
5625 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5626 sent to the function while XXX_*STRING will not allocate or copy
5627 the data into the buffer. Instead it sets the pointer from the
5628 buffer into the pointer sent as argument (XXX_*STRING used to
5629 require that the pointer must be allocated already). This change
5630 makes this whole thing a bit more consistent and more optimized
5631 (note that the data returned in the unformatting with XXX_*STRING
5632 must not be freed now). The routines return now -1 on error.
5634 o Tried to find all code that use buffer_format and buffer_unformat
5635 and added return value checking to prevent formatting and
5636 especially unformatting errors and possible subsequent fatal
5639 o Changed ske->x and ske->KEY to mallocated pointers in
5640 lib/silcske/silcske.h. Fixed possible data and memory leak.
5642 o Added return value checking to all *_parse* functions. Fixed
5643 many memory leaks as well.
5645 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5646 so that buffer overflows would not happen. All code now also
5647 checks the return value as it can fail.
5649 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5651 * Added reconnection support to server if the normal server looses
5652 its connection to the router (for example if router is rebooted).
5653 The server performs normal reconnection strategy implemented
5654 to the server. Affected file silcd/server.c.
5656 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5658 * Added new packet type SILC_PACKET_SET_MODE that is used to
5659 distribute the information about changed modes (for clients,
5660 channels and clients channel modes) to all routers in the
5661 network. Updated the protocol specification accordingly.
5663 Added functions into silcd/packet_send.c and
5664 silcd/packet_receive.c: silc_server_send_set_mode,
5665 silc_server_set_mode.
5667 Added new files silcmode.[ch] into lib/silccore that implements
5668 the encoding and decoding of Set Mode Payload. Added new type
5669 SilcSetModePayload. Moved the definitions of different modes
5670 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5672 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5674 * Oops, a little mistake in server's connection authentication
5675 protocol. The protocol is not ended with FAILURE but with
5676 SUCCESS if the authentication is Ok. :) Affected file is
5679 * Implemented NICK_CHANGE notify handling in server in the file
5680 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5681 the local clients on the channel. After the changing nickname
5682 in router environment snhould work and the [<unknown>] nickname
5683 should appear no more.
5685 The silc_server_replace_id function that receives the Replace ID
5686 payload now sends the NICK_CHANGE notify type also in the file
5687 silcd/packet_receive.c
5689 * Changed WHOIS and IDENTIFY command to support the maximum amount
5690 of arguments defined in protocol specs (3328 arguments). This
5691 fixed a bug that caused problems when there were more than three
5694 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5696 * Added extra parameter, command identifier, to the
5697 silc_client_send_command so that explicit command identifier
5700 Changed that ID list routines uses specific command identifier
5701 when sending WHOIS/IDENTIFY requests to the server so that they
5702 can be identified when the reply comes back.
5704 Affected files lib/silcclient/command.[ch],
5705 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5707 * Added `sender' argument to silc_server_packet_send_to_channel
5708 to indicaet the sender who originally sent the packet to us
5709 that we are now re-sending. Ignored if NULL. Affected file
5710 silcd/packet_send.[ch].
5712 * Added some server statistics support in silcd/server_internal.h
5713 SilcServerStatistics structure and around the server code. Also
5714 send some nice statistics information when client is connecting
5717 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5719 * Fixed channel ID decoding in server's JOIN command reply in
5720 silcd/command_reply.c
5722 * Fixed braodcasting of replace ID payload to not to send it if
5723 we are standalone server in silcd/packet_receive.c.
5725 * Fixed all channel message sending routines to not to send
5726 packets to clients that has router set, since they are routed
5727 separately in the same function earlier. Affects file
5728 silcd/packet_send.c and all channel packet sending functions.
5730 * In USERS reply, res_argv[i] are not allocated, the table
5731 is allocated. Thus changed that free the table, not its
5734 * In server's whois_check and identify_check if the client is
5735 locally connected do not send any WHOIS commands - they are not
5738 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5740 * Fixed some minor bugs in client when sending WHOIS command. The
5741 arguments was in wrong order.
5743 * Removed statis function add_to_channel from server in
5744 silcd/command.c that was previously used with the joining but
5747 * Tested USERS command in router environment successfully with two
5748 routers, two servers and two clients.
5750 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5752 * Reorganized the USERS command and command reply in client library
5753 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5754 When the command is given by user we register a pending command
5755 callback that will reprocess the command after the reply has been
5756 received from the server. When reprocessing the packet we then
5757 display the information. Thus, the USERS information is displayed
5758 now in the command callback instead of in the command reply
5759 callback. The processing of the command is same as previously
5760 when server has sent the command reply in the JOINing process.
5762 * Added to USERS command in silcd/command_reply.c to join the client,
5763 we didn't use to know about, to the channel after we've created
5764 a client entry for it. Also, for clienet we did know already still
5765 check whether it is on the channel or not and add it if not.
5767 * Removed silc_server_command_join_notify as the function and its
5770 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5772 * Changed the client's pending command handling to the same as the
5773 server's pending command handling. It is also now possible to
5774 execute command reply functions from other command reply
5775 function as the function callbacks for commands and command
5776 replies are one and same. The pending commands are not static
5777 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5778 in client connection context. Thus, pending commands are server
5779 connection specific as it is convenient.
5781 Changed the function silc_client_command_pending and
5782 silc_client_command_pending_del and added new function
5783 silc_client_command_pending_check. Removed the
5784 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5787 * Added cmd_ident, current command identifier, to the client
5788 connection context in lib/silcclient/client.h to keep track on
5789 command identifiers used in command sending. Client's command reply
5790 function handling now supports the mandatory command identifiers.
5792 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5793 funtions in client to fully support pending command callbacks.
5795 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5796 as one of the arguments to the application in the command reply
5799 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5800 before first releasing SILC but came back. Now it is removed again
5801 and should come back nomore. The FORWARDED flag was used only
5802 by the JOINing procedure by forwarding the command packet to router.
5803 Now, the JOINing procedure has been changed to more generic (due
5804 to various router environment issues) and FORWARDED is not needed
5805 anymore for anything. The protocol specification is yet to be
5808 Now, removed silc_server_packet_forward from server and the flag
5809 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5811 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5813 * Renamed NAMES command to USERS command. The NAMES was named that
5814 due to historical reasons. Now it is renamed. Also, rewrote
5815 parts of the USERS command. The nickname list is not sent anymore
5816 by the server. Only Client ID and mode lists are sent in the USERS
5817 command. Changed this also to the protocol specification.
5819 The client now resolves the names and stuff after it receives
5820 the USERS list from the server when joining to the channel.
5822 * WHOIS and IDENTIFY commands has been changed to support multiple
5823 Client ID's per command. One can now search for multiple users
5824 in the network by sending only one WHOIS or IDENTIFY command.
5825 Changed the code and the protocol specifications.
5827 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5828 uses silc_server_command_whois_parse to parse the request. */
5830 * If normal server, do not parse the WHOIS and IDENTIFY requests
5831 before sending it to the router. Saves some time.
5833 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5835 * Fixed JOIN command on client library. Wrong number of arguments
5836 used to crash the client.
5838 * Added silc_server_channel_has_global function to check whether
5839 channel has global users or not.
5841 * Added silc_server_channel_has_local function to check whether channel
5842 has locally connected clients on the channel.
5844 * The silc_server_remove_from_one_channel now checks whether the
5845 channel has global users or not after given client was removed from
5846 the channel. It also checks whether the channel has local clients
5847 on the channel anymore. If it does not have then the channel entry
5848 is removed as it is not needed anymore.
5850 * The silc_server_notify now checks on JOIN notify whether the joining
5851 client is one of locally connected or global. If it is global then
5852 the channel has now global users on the channel and that is marked
5853 to the channel entry. Also, it now saves the global client to
5854 global list who is joining and JOINs it to the channel. This is
5855 for normal server, that is.
5857 Changed silc_server_send_notify_on_channel,
5858 silc_server_packet_relay_to_channel and
5859 silc_server_packet_send_to_channel check if we are normal server
5860 and client has router set (ie. global client) do not send the
5861 message to that client, as it is already routed to our router.
5863 * Implemented LEAVE notify type handling in silc_server_notify
5866 * Tested LEAVE command in router environment successfully. Tested
5867 with two routers, two servers and two clients.
5871 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5873 * Implemented SIGNOFF notify type handling in silc_server_notify
5876 * silc_server_remove_id now removes the client entry from all channels
5877 it has joined and thusly sends SIGNOFF notify type.
5879 * Rewrote the NAMES list generation in server by removing two excess
5880 loops. The lists are created now inside one loop.
5882 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5884 * silc_server_remove_channel_user checks now also global list
5885 for channel and client.
5887 * silc_server_new_channel_user checks now both local and global
5888 list for channel and client. Fixed a bug in client id decoding.
5889 Used to decode wrong buffer.
5891 * silc_server_channel_message checks now both local and global
5892 list for channel entry.
5894 * Tested channel joining (hence JOIN) in router environment
5895 successfully. Tested with two routers, two servers and two
5898 * Tested channel message sending in router environment successfully.
5900 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5902 * Added silc_server_save_channel_key into server.[ch] to save the
5903 received channel key in Channel Key payload processing. It is
5904 also used in JOIN command reply handling.
5906 Equivalent function silc_client_save_channel_key added into
5907 client.[ch] into client library.
5909 * Changed JOIN command reply to send information whether the channel
5910 was created or not (is existing already) and the channel key
5911 payload. Changed protocol specs accordingly.
5913 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5914 the request was sent by ID and not by nickname. Crashed on
5917 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5919 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5920 now correctly save the received data.
5922 * silc_server_free_sock_user_data now notifies routers in the
5923 network about entities leaving the network.
5925 At the same time implemented functions silc_server_remove_id
5926 and silc_server_send_remove_id to receive and send REMOVE_ID
5927 packets. The packet is used to notify routers in the network
5928 about leaving entities. The ID removed will become invalid in
5931 * Added function silc_idlist_del_server into server. Removes and
5932 free's server entry from ID list.
5934 * silc_server_private_message function now checks, if we are router,
5935 that the destination ID really is valid ID, naturally.
5937 * In router when NEW_ID packet is received (for new client) the
5938 hash of the Client ID is saved in the ID Cache but the
5939 client->nickname is set to NULL, instead of putting the hash
5942 IDENTIFY command now also checks that client->nickname must be
5943 valid. If it is not if will request the data from the server who
5944 owns the client. Added new function
5945 silc_server_command_identify_check.
5947 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5948 to set the command to already allocated Command Payload.
5950 * Tested private message sending in router environment with two
5951 routers, two servers and two clients. Fixed minor bugs and now
5954 * Fixed segfault from client's NAMES command. Used to crash if
5957 * Forwarded packets must not be routed even if it is not destined
5958 to the receiver. Changed server code comply with this.
5960 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5962 * Added `require_reverse_mapping' boolean value to ServerParams
5963 structure. If TRUE (not default) the server will require that
5964 the connecting host has fully qualified domain name.
5966 If the reverse mapping is not required and hostname could not be
5967 found the IP address is used as hostname.
5969 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5971 * Implemented version string checking to both client and server.
5972 The check is incomplete currently due to the abnormal version
5973 strings used in development version of SILC.
5975 * Changed all command functions in server to use the new
5978 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5980 * Changed char *data to unsigned char *data in ID Cache system to
5981 support binary data as ID Cache data. Changed code to support
5982 binary data in lib/silccore/idcache.c.
5984 * Renamed silc_server_packet_relay_command_reply to
5985 silc_server_command_reply as it is normal packet receiving
5986 function. Rewrote the function to accept command replys for
5987 servers and not only for clients.
5989 * Mark remote router always as registered server if we are connecting
5990 to it. Otherwise, commands sent by the router to us are ignored.
5992 * All ID List find routines now returns the ID Cache Entry pointer
5993 as well if requested.
5995 * WHOIS command works now in router environment, tested with two
5996 routers, two servers and two clients.
5998 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5999 in router environment (as it is almost equivalent to WHOIS) but
6000 hasn't been tested thoroughly. Added new functions:
6002 silc_server_command_identify_parse
6003 silc_server_command_identify_send_reply
6004 silc_server_command_identify_from_client
6005 silc_server_command_identify_from_server
6007 * Disabled route cache adding because adding two different ID's with
6008 same IP replaces the old cache entry thus giving wrong route.
6009 The entry->router->connection is always the fastest route anyway
6010 so route cache may not be needed. Of course, new routes maybe
6011 established after receiving the ID when the entry->router->connection
6012 might not be anymore the most optimal.
6014 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6016 * Add route cache for received ID for fast routing.
6018 * Added silc_server_packet_route to route received packet on router
6019 that is not destined to us.
6021 * Renamed silc_server_get_route to silc_server_route_get.
6023 * Added id_string and id_string_len fields into SilcServer to
6024 include encoded ServerID for fast comparing without excess
6025 encoding of the ID's.
6027 * Cleaned up WHOIS command on server side. Added following static
6030 silc_server_command_whois_parse
6031 silc_server_command_whois_check
6032 silc_server_command_whois_send_reply
6033 silc_server_command_whois_from_client
6034 silc_server_command_whois_from_server
6036 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6037 arguments in command replies. All command functions should be
6038 updated to use this macro.
6040 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6042 * Minor typo fixes on command reply handling on server.
6044 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6046 * Added silc_server_command_add_to_channel internal routine to add
6047 the client to the channel after router has created the channel and
6048 sent command reply to the server.
6050 * Added generic silc_server_send_command to send any command from
6053 * Use static buffer with ID rendering instead of duplicating data.
6055 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6057 * Fixed a channel user mode bug when joining to a channel server gave
6058 everybody channel founder rights, oops.
6060 * We mark ourselves as the router of the incoming server connection
6061 if we are router ourselves. This way we can check in some packet
6062 sending functions whether it is locally connected server. For
6063 incoming router connections we put NULL.
6065 * For router sending packets locally means now always sending the
6066 packet cell wide; to local clients and local servers. For normal
6067 server sending packet locally means sending it to only local
6070 * Fixed the JOIN command to really work in router environment. If the
6071 channel is created it is always created by the router. Router is
6072 also responsible of making the initial joining to the channel,
6073 sending JOIN notify to the sending server and distributing
6074 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6075 does not exist server doesn't do anything else but forward the
6076 command to the router which performs everything.
6078 * Added silc_server_send_channel_key function to send the Channel Key
6081 * Added silc_server_create_channel_key to create new channel key. The
6082 channel key is now re-generated everytime someone joins or leaves
6083 a channel, as protocol dictates. Note: channel->key_len is the
6086 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6088 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6089 packet_receive.[ch] to separate packet sending and receiving
6090 routines. The server.[ch] now includes everything else including
6091 actual packet processing (writing and reading data) and other
6094 Renamed silc_server_private_message_send_internal to
6095 silc_server_send_private_message. The routine is still though
6096 used only to relay private messages as server does not send
6097 private messages itself.
6099 Renamed silc_server_new_channel to silc_server_create_new_channel
6100 and added new function sicl_server_new_channel that handles the
6101 incoming New Channel packet. Added also new sending function
6102 silc_server_send_new_channel to send New Channel Payload.
6104 * Added new function silc_server_notify to process incoming notify
6105 packet to the server/router. Server may then relay the notify
6106 to clients if needed.
6108 * Added new function silc_server_new_channel_user to process incoming
6109 New Channel User packet. Router will redistribute the packet and
6110 send JOIN notify to its local clients and locally connected servers
6111 if needed. Normal server will send JOIN notify to its local client
6112 on same channel when received this packet. Added also corresponding
6113 sending function silc_server_send_new_channel_user to sent the
6116 * Added boolean route argument to send_notif_to_channel and
6117 packet_send_to_channel functions to attempt to route the packet
6118 if it is TRUE and send only locally if it is FALSE.
6120 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6122 * silc_server_replace_id now broadcasts the received replace ID
6123 packet if it is not broadcast packet already. The router must
6124 broadcast to inform other routers about changed ID.
6126 * Added backpointer to server's router into SilcServer context in
6127 silcd/server_internal.h.
6129 * Fixed silc_server_packet_broadcast to send correct broadcast
6132 * The channel key is now distributed to the local client as soon
6133 as it is received from the router (in router environment) so that
6134 no other packet may be sent for the channel until client has
6137 * silc_server_remove_channel_user now broadcasts the received
6138 Remove Channel User packet if it is not broadcast packet already.
6139 The router must broadcast to inform other routers about removed
6142 * Added users field into SilcPacketContext that is a reference count
6143 of the context. One can increase the reference count by calling
6144 silc_packet_context_dup which is now changed to just increase the
6145 reference count instead of duplicating the data. The reference
6146 count is decresed by calling silc_packet_context_free that will
6147 free the data after the reference count hits zero.
6149 For now on the packet context and everything allocated into it
6150 (including the raw packet from network) must be freed by calling
6151 the new silc_packet_context_free function. Added also new function
6152 silc_packet_context_alloc that must be used now to allocate the
6153 context. This also means that if a routine is asynchronous from
6154 silc_[client/server]_packet_parse_type the packet context must
6155 be duplicated by calling silc_packet_context_dup. Otherwise it
6156 gets free'd after silc_[client/server]_packet_parse_type returns.
6157 Also, one must remember that if packet is duplicated then its
6158 reference count must be decresed by calling the free function as
6159 many times as it was duplicated.
6161 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6162 from both client and server.
6164 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * Made joining to a channel working in router environment.
6168 * Cleaned up JOIN command on server side and create function
6169 silc_server_command_join_channel internal routine to make the
6172 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6174 * Changed silc_command_pending list to SilcDList. Also, added
6175 `ident' field to SilcServerCommandPending structure to identify
6176 the reply and to call correct callback.
6178 Added silc_server_command_pending_check function to replace the
6179 corresnponding macro. The silc_command_pending list is not
6182 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6183 to set identifier to previously allocated Command Payload. It
6184 is used to set identifier for command when resending Command
6187 * Added silc_command_payload_encode_payload to encode Command
6188 Payload buffer from SilcCommandPayload structure.
6190 * Added silc_argument_payload_encode_payload to encode Argument
6191 payload buffer from SilcArgumentPayload structure.
6193 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6195 * Changed WHOIS command to support router connection on server side.
6196 The whois request is always sent to router unless the server is
6197 standalone server. After server has received the reply from the
6198 router will it send the reply to the client.
6200 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6201 broadcast received broadcast packet. The function is used only
6202 by router. The broadcast packet is always sent to the router's
6205 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6206 render given ID to printable string, for log files for example.
6208 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6210 * Made basic router to router connections working. At least they
6211 can now connect to each other but nothing really works the way
6212 they are supposed - yet.
6214 * Added new initiator token to RouterConnection configuration
6215 file in silcd/serverconfig.[ch]. It is used to tell whether we
6216 are the initiator to the remote router or whether we'll expect
6217 the other end to connect.
6219 * Moved registering of listener task to silc_server_init, hence
6220 the server starts listenning as soon as it is run, even if it
6221 does not have connections to other routers. Let's see how well
6224 * Changed default connection retry timeouts for more suitable in
6227 * Removed cipher and such arguments from silc_idlist_add_client
6228 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6229 Added new function silc_idlist_add_data to add the keys and stuff
6232 * Added SilcIDListData structure and added it to SilcClientEntry
6233 and SilcServerEntry as their first field in the structure. This
6234 way we can explicitly cast the ID entries to the SilcIDListData
6235 structure and get common data for the entries. In past, we had
6236 to first check what type of connection it is and then cast it to
6237 correct ID entry type. Now, we can directly cast the opaque
6238 pointer to the SilcIDListData (no matter what ID entry it actually
6239 is) and get the data needed.
6241 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6243 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6244 in some circumstances even if threre were timeout tasks, though not
6245 IO tasks, but tasks anyway. Now fixed.
6247 * Defined SilcServerConnection structure to hold connection specific
6248 stuff about directly connected servers and routers. The definition
6249 is currently in silcd/server_internal.h. I thought about having
6250 a bit more important role fro this struct but for now it is used
6251 only when connecting to other server (or router actually).
6253 * Added connecting retry support in server when connecting to
6254 router(s). The retry feature implement exponential backoff
6255 algorithm. Also, added SilcServerParams structure to hold default
6256 parameters for server. For now, it include these retry settings
6257 and are hard coded. After server is moded to be as Silc Server
6258 Library this structure will be more important.
6260 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6262 * Changed client librarys channel->clients table to SilcList and
6263 changed code accordingly.
6265 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6267 * Changed client's channel table to SilcList and changed code
6268 accordingly. Also changed SilcChannelClientEntry to include back-
6269 pointer to the channel so that client entry can use that structure
6270 as list as well and we have fast cross-reference to the channel.
6271 This change dramatically decreased the complexity of channel
6272 handling with client entry and vice versa (removed one extra
6273 loop when searching for channel entry from many functions).
6275 * Changed server->sim from table to SilcDList and changed code
6278 * NAMES command can now be used from user interface. It will show
6279 the user list on the channel, neatly.
6281 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6282 Code now saves realname of the user if it becomes available.
6284 * Renamed configure.in to configure.in.pre and made ./prepare
6285 script to automatically add correct version string to
6286 configure.in which it creates from configure.in.pre.
6288 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * NAMES command reply now shows users mode with the nickname when
6293 * Moved silc_client_ch[u]mode[_char] functions from
6294 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6295 place sucks, they are utility functions and should be in some
6298 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6300 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6303 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6307 * Added TRQ (efficient deque and list library) into lib/trq. This is
6308 a very good list library that is currently used in the SILC. Defined
6309 SilcList API over the library because I didn't like the API very
6310 much. See lib/trq/silclist.h for the API and examples of how to
6311 use the API. Fixed various places in the code to use the new
6312 SilcList API. The SilcList is meant for lists that has a structure
6313 already defined as a list. It is not suitable to add just some
6314 context to the list (in TRQ, the context is the list actually).
6316 So, I defined SilcDList that can be used for the purpose where
6317 predefined list structure does not exit. This can be used as
6318 such list. Now some context just can be added to the SilcDList.
6319 Currently this list is not used in the SILC just yet, though there
6320 are a lot places where this can replace dynamically allocated
6321 tables and I will fix these places, later, to use SilcDList.
6322 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6323 and use TRQ internally).
6325 Also fixed some annoying warning messages that the original TRQ
6326 code generated. Also minor changes to TRQ's Makefile.in.
6328 * Added support for querying by Client ID to both WHOIS and
6329 IDENTIFY commands into server, as required by the protocol.
6331 * Removed method function pointers from SilcBuffer structure. They
6332 weren't used to anything and just increased the context size for
6333 no good reason. This change also made silc_buffer_alloc and
6334 silc_buffer_free functions inline functions.
6336 * Disabled command flooding detection support until it's fixed so
6337 that it accepts commands in but does not execute them more than once
6340 * Added silc_net_localhost(), to return local hostname, into
6341 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6342 that must be initialized before calling silc_client_init.
6344 * Added new function: silc_server_send_notify_on_channels to send
6345 notify messages to all channels client has joined. It is assured
6346 that the message is sent only once per client.
6348 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6349 lib/silcutil/silcutil.[ch] as silc_format function. The new
6350 function is generic and is used by server as well, not only by
6351 the logging routines.
6353 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6354 the provided version string was not acceptable. Added new function:
6355 silc_ske_check_version into lib/silcske/silcske.h. The function
6356 must be implemented by the application (client or server) and it
6357 does not reside in the SKE library. The function checks the version
6358 string remote end sent.
6360 * Added back pointers (to opaque context and to SilcSocketConnection)
6361 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6363 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6364 duplicate packet context structure.
6366 * Changed `notify' client operation to send same arguments as client
6367 receives from server except for ID's. ID's are mapped to correct
6368 ID entry and that is returned. Also, if channel entry is not sent
6369 by server but the notify is for channel the channel entry is sent
6370 to application (otherwise application doesn't know that it is for
6371 channel (library gets it from packet's Destination ID)).
6373 * Added silc_client_remove_from_channels into client library to
6374 remove a client from all channels it has joined to. Used when
6375 received SIGNOFF notify from server. Added also new function
6376 silc_client_replace_from_channels to replace old ID entry with
6377 new ID entry on all channels. Used when received NICK_CHANGE
6380 * Fixed ID Cache list handling in silc_idlist_get_client in
6381 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6382 to get (or query) client by ID.
6384 * Updated TODO list.
6386 * Added connection authentication status message defined by the
6387 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6388 support for these into the code in client and server side.
6390 * Added generic function silc_client_send_command to send any command
6391 with variable argument list. Application should use this function
6392 to send commands if the command functions provided by the library
6393 does not suite for the application's user interface needs.
6395 * Added new `failure' client operation. Application is notified about
6396 received failure packet if client is executing a protocol. In this
6397 case the protocol's execution has failed.
6399 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6400 is required by the protocol.
6402 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6403 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6406 * Added status flag to SilcSKE object to indicate realtime status
6407 of the SKE protocol.
6409 * Application receives now exactly same command reply arguments as
6410 the library receives from server. However, if ID is received the
6411 corresponding ID entry is returned to the application (eg. Client
6412 ID is mapped to correct SilcClientEntry entry and that is returned).
6413 Changed command_reply client operation due to this change.
6415 * Changed all ID's in commands and in command replys as ID Payloads.
6416 Change affected both client and server side codes.
6418 All ID's sent in SILC network (with execption of ID's in SILC
6419 Packet header) are sent in ID Payload to support variable length
6422 * Server now notifies nick changes and notifies all clients on
6423 the channels about the new nickname (about the new Client ID,
6426 * Implemented CMODE command to change channel modes. Supports all
6427 channel modes defined by the protocol specs except ban and invite
6428 lists. (Also, private channel key mode is supported but support for
6429 setting private channel key in client is missing, thus, this mode
6430 has no effect on client side (except that server requires that the
6431 client uses private channel key and normal channel traffic does not
6434 Also, invite mode works per se, but INVITE command does not work
6435 yet correctly, so you can set channel as invite only channel but
6436 inviting clients to the channel does not work (it is yet to be
6437 thought what's the best way to do it).
6439 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6440 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6441 Implemented CUMODE command to change user's mode on the channel.
6442 Supports all modes defined by the protocol specs.
6444 * Added NAMES command reply to return users modes on the channel.
6446 * Removed unnecessary and slow ciphers from lib/silccrypt.
6448 * Set SO_KEEPALIVE option to connection sockets by default.
6450 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6452 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6453 redefined the Notify Payload into protocol specs.
6455 * Added silc_id_payload_parse_id to get ID directly from raw
6458 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6460 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6461 accept searching by Client ID as well.
6463 * Added support for LEAVE and SIGNOFF notify types in client library.
6465 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6466 to parse ID Payload from raw data.
6468 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6470 * Added flags parameter into silc_ske_assemble_security_properties
6471 function in lib/silcske/silcske.[ch].
6473 * Changed notify client operation to fit better for notify messages
6474 sent by server. The notify payload received from server is now
6475 passed to the application (after parsing it to SilcNotifyPayload).
6476 It is application's responsibility to retrieve the arguments
6477 from the payload and show the message the way it wants. The message
6478 sent by server is implementation specific.
6480 * Changed public keys to comply with the protocol specification.
6481 Old public keys are not supported anymore and are not compatible.
6483 * Removed nickname from Channel Payload as the latest draft removed
6484 it. The client must resolve the nickname from the NAMES command
6485 reply received when it joined the channel.
6487 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6489 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6491 * Fixed some errors in protocol specification drafts.
6493 * Created lib/silccore/silcnotify.c to implement Notify Payload
6494 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6495 generic payloads described by protocol specifications. The file
6496 includes implementations for ID Payload and Argument Payload.
6498 * Changed Command Payload implementation to use the new Argument
6499 Payload. Changed command_xxxx_payload to command_payload_xxxx
6500 to comply with SILC coding conventions.
6502 * Added suppport for Argument Payload handling in Notify Payload
6503 implementation as protocol requires it. Added the new support
6504 into server and client lib as well.
6506 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6508 * Added support for multiple nicknames on same channel. [n] is
6509 added locally to the nickname if there are more than one same
6510 nicknames on the channel.
6512 * Server now sends all nicknames that matched WHOIS request.
6513 Client also shows the list received from server.
6515 * Added TOPIC command to client side. User can now set and show
6516 current topic on channel.
6518 * Added MOTD command to client and server. Also, server sends the
6519 motd when client connects to the server.
6521 * Changed version strings to comply ISO 8601.
6523 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6525 * Fixed protocol error handling in client library. It should now
6526 cope even if the SKE fails for some reason.
6528 * Made new protocol specification drafts for submitting to IETF.
6530 * Implemented TOPIC command to server in silcd/command.c.
6532 * Added two new notify types into lib/silccore/silcnotify.h:
6533 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6534 notify nickname change and topic setting/change on a channel.
6536 * API change of command_reply operation in client library. The
6537 application gets now the status type received from server as well.
6539 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6541 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6543 * Cras fixed and optimized the packet handling even further and
6544 it should work now. Minor change to the prototype of function
6545 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6547 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6549 * Added new function into lib/silcutil/silcschedule.[ch]:
6550 silc_schedule_with_fd to select() a specified fd. The function
6551 returns after timeout expires or data arrives or goes. The
6552 function is used by packet routines to wait that all data is
6553 received from network.
6555 * Fixed data reading from network in lib/silccore/silcpacket.c.
6556 The code now assures that all data is read from the fd and then
6557 continues packet processing. This was a bug fix since the code
6558 used to drop some data in some circumstances.
6560 * Added new function into lib/silcclient/client.[ch]:
6561 silc_client_start_key_exchange to start key exchange after
6562 connection has been established to server. The code internally
6563 now uses this funtion but its main purpose was to provide it
6564 for applications that perform their own connecting. After
6565 application has created a connection it merely calls this
6566 function to start the key exchange between client and server.
6567 The library takes care of everything else after that.
6569 Updated also lib/silcclient/README to explain the usage of
6572 * Do not send to application information that connection has
6573 been established. Application gets notified it by connect
6576 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6578 * Applied cras's patch to add silc_schedule_one function. The
6579 function runs scheduler once and returns.
6581 * Fixed the scheduler after cras messed it up. The timeout
6582 handling works now as it's supposed to work.
6584 * Added into lib/silccore/ silcnotify.h to include notify
6585 message types support. Changed silc_server_send_notify*
6586 functions, in server.[ch], to support those new notify types.
6587 Added the support for the notify types into client library,
6588 as well. Added new notify client operation into ops.h in
6591 * Changed silc_server_packet_send_to_channel to send normal
6592 packets instead of just channel message packets. The function
6593 is now used to send the notify packets to channels. It is not
6594 used to send channel message packets anymore, as server never
6597 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6598 va_arg()s as it seems to require it nowadays. I guess, if SILC
6599 is compiled with older va_arg() the new code should work anyway.
6601 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6603 * Splitted core library. Core library (lib/silccore) includes
6604 now only SILC protocol specific core (and common) components.
6605 Created new utility library (lib/silcutil) that includes more
6606 generic purpose stuff. The stuff for util library was taken
6607 from the old core library. This was minor and easy split.
6609 * Created SILC Client Library (lib/silcclient) that includes
6610 implementation of the SILC client without user interface. This
6611 was major move from silc/ directory. The code has been changed
6612 so that it is transparent towards the user interface. The
6613 silc/ directory includes now the same user interface as before
6614 and it uses the new client library. Read lib/silcclient/README.
6615 Basicly, the client library performs everything else related
6616 to SILC except user interface handling. Also, configuration
6617 files are considered to be part of user interface and library
6618 does not handle them.
6620 This change also changed a lot of structures, function naming etc.
6621 Most important change was that SilcClientWindow object was
6622 renamed to SilcClientConnection in the client library. Created
6623 also new file lib/silcclient/ops.h. Also added new files
6624 silc/local_command.[ch] and silc/client_ops.[ch].
6626 All these changes were made to make it easier for user interface
6627 designers to create what ever user interface for the SILC client
6630 It is also expected that the server will be moved to lib
6631 directory as well and SILC Server Library will be created;
6632 sometimes in the future.
6634 * Removed Local commands from lib/silccore/silccommand.h as
6635 they are application specific and new client library does not
6636 handle any of those anymore.
6638 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6639 old client implementation in silc/.
6641 * Added support for callback functions in SILC_LOG_* macros.
6642 Application can now set its own callbacks that will be called
6643 instead of using the default functions that will always print
6644 the debug messages to stderr (or stdout). Also, debugging can
6645 now be disabled by setting silc_debug to FALSE and re-enabled by
6646 setting it to TRUE. Note, that logging will still work even
6647 if debugging is disabled.
6649 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6650 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6651 silc_log_reset_debug_callbacks.
6653 * To enable debugging in silc client one must give now -d
6654 option on command line.
6656 * Changed silc_schedule_init to automatically allocate task queues
6657 if they are not allocated before calling it.
6659 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6661 * Added GMP 3.1 into math library.
6663 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6665 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6666 a channel in SILC network. The packet is used by servers and
6667 routers to notify other routers that user has left a channel.
6668 This little feature was missing until now. Added the feature
6669 to protocol specification as well.
6671 Added functions: silc_server_send_remove_channel_user and
6672 silc_server_remove_channel_user into server.[ch].
6674 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6675 lib/silccore/silcpacket.h. However, they are not implemented
6678 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * Fixed joining to a channel and sending channel messages
6681 between server and router. The channel message sending should
6682 now work inside a cell.
6684 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6686 * Fixed the private message sending between server and router.
6687 The private message sending should now work inside a cell.
6689 * Added silc_server_replace_id into server.[ch] to replace
6690 existing ID in the SILC network.
6692 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6693 and silc_idlist_replace_server_id into idlist.[ch] in server.
6695 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6697 * Fixed the server to server connections. Server can again now
6698 connect to router. Router to router connections probably does
6701 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6703 * Added dynamic protocol registering support. Now protocols can
6704 registered and unregistered on the fly. Patch by cras.
6706 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6708 * Added lib/contrib directory to hold routines that some platforms
6709 don't have but are needed by SILC.
6711 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6712 into lin/contrib to provide getopt() and getopt_long() for
6713 those who don't have it.
6715 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6717 * Added AWAY command to client. When away message is set and
6718 client receives a private message packet the client automatically
6719 replies to the sender with the away message.
6721 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6722 bug seemed to be the cause of recent problems when compiling
6725 * Added version detection support to SKE protocol specification
6726 and added the new changes to the SKE implementation as well.
6727 There were other minor changes in the SKE protocol as well.
6729 Many changes in lib/silcske/silcske.[ch] and in
6730 lib/silcske/payload.[ch].
6732 * Added ^U functionality, clear input line. Patch from cras.
6734 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6736 * Mainly small bugfixes on core library. Fixed some debugging
6737 logging and buffer overflow in silclog.c.
6739 * Updated config.sub and config.guess on the distribution tree.
6741 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6743 * Added command lagging support in server. Client may execute
6744 commands now only once in two seconds.
6746 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6748 * Optimized packet reception. MAC computation and checking is now
6749 also more optimized. A lot previously duplicated code is now
6750 used as generic by both client and server.
6752 * Fixed key pair generation in clientutil.c
6754 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6756 * Added into lib/silccore/silcbufutil.[ch] new function;
6757 silc_buffer_realloc.
6759 * Moved generic packet sending/encryption functions to
6760 lib/silccore/silcpacket.[ch] from client and server. Some
6761 rewriting of the functions.
6763 * Moved all generic packet reception/decryption functions to
6764 lib/silccore/silcpacket.[ch] from client and server. The
6765 packet processing is now much cleaner in both client and server.
6766 These were major changes in both client and server.
6768 * Created many common functions in server to do packet sending.
6769 Previously code were duplicated a lot, this has been removed
6772 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6774 * Rewrote major parts of the ID cache system. Don't know
6775 whether it is better now or not but at least the API is more
6778 * Major rewrite on ID cache stuff on client because of the ID
6779 cache API changes. Added idlist.c to client.
6781 * Also major rewrite on ID cache stuff on server as well.
6782 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6783 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6784 in hand, instead they are all put into the ID cache system now.
6785 All server_idlist_* routines uses ID cache now instead of
6786 traversing its own lists (those lists does not exist anymore).
6787 SilcIDList though still exists. Also, SilcXXXEntry's are
6790 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6792 * Finally made the SKE implementation compliant to the protocol
6793 specification. All mp integers are now binary encoded as
6794 opposed being HEX encoded.
6796 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6799 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6800 functions: silc_[encode/decode]_pem. Also added function
6801 silc_encode_pem_file to PEM encode with newlines ('\n') for
6804 * SILC public keys are now encoded either PEM or binary. Same
6805 option is for private keys as well. By default private keys
6806 are binary encoded and public keys PEM encoded. Silly HEX
6807 encoding were removed.
6809 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6810 function to create fingerprints.
6812 * Fixed a bug in SHA1; does not change the original data anymore.
6814 * Partly implemented INFO command on client and server side.
6815 Fixed CLEAR command. Changes to SERVER command; show current
6816 server(s) when giving command without arguments. Added
6817 VERSION command to client.
6819 * Added check to server that unregistered connections cannot
6820 execute commands (unless it is specificly allowed).
6822 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6824 * Fixed screen refresh.
6826 * Fixed channel joining bug from client. On some circumstances
6827 client tried to join to a channel it had already joined.
6829 * Added public key verification process into client's protocol.c.
6830 The client now verifies the public key from user and saves
6831 it into ~./silc/serverkeys/ directory.
6833 Added into: clientutil.[ch]: silc_client_verify_server_key.
6835 * Changed SKE protocol's silc_ske_initiator_finish function
6836 to accept callback function that verifies the received public
6837 key. Removed old silc_ske_verify_public_key function.
6839 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6841 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6842 silc_pkcs_private_key[_data]_set.
6844 * Made the password and public authentication more cleaner in
6845 server's protocol.c.
6847 * Removed historic and obsolete protocol `channel_auth' from
6848 both client and server.
6850 * Removed wrong way of sending command status messages from
6851 server to client in server's command.c. The old way violated
6852 protocol specification.
6854 Changes to silccore/silccommand.[ch]: removed
6855 silc_command_encode_status_payload -> not needed anymore,
6856 changed silc_command_encode_payload_va to accept extra
6857 argument on variable argument list. The argument type must
6858 now be provided to the function. Also, added new function:
6859 silc_command_encode_reply_payload_va which is same as
6860 normal command_encode_payload_va except command status type
6861 is provided as extra argument.
6863 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6865 * Added ~./silc directory handling. The directory includes the
6866 public and private keys for the client.
6868 Added silc_client_check_silc_dir, silc_client_create_identifier
6869 and silc_client_load_keys.
6871 * Implemented SILC protocol compliant public key. Added public
6872 and private key saving to and loading from files.
6874 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6875 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6876 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6877 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6878 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6880 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6881 silc_pkcs_load_[public/private]_key.
6883 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6885 * Added silc_server_get_route (route.[ch]) to get connection
6886 data for the fastest route for given ID.
6888 * Implemented INVITE command on client and server. The command
6889 were re-defined in the SILC Protocol Specification and the
6890 implementation now complies with the specification.
6892 * Implemented PING command on client and server.
6894 * Implemented NAMES command on client and server. The server side
6895 supports currently only normal server not router server yet.
6896 Some changes to NAMES definition in SILC protocol specification.
6898 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6900 * Implemented LEAVE command on client and server.
6902 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6903 again. This change was made to the protocol as well. Server
6904 should not violate the protocol specification anymore.
6906 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6908 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6909 was tested. SOCKS4 was not but should work anyway.
