1 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Defined DLLAPI into silcincludes.h and silcwin32.h for
4 Win32 DLL. extern's in header files are now declared with
7 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
9 * Fixed private message handling. It used some old code that
10 caused the client to crash. Affecte file is
11 lib/silcclient/client_prvmsg.c.
13 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
15 * Added function silc_client_add_channel,
16 silc_client_replace_channel_id, and removed functions
17 silc_client_new_channel_id and silc_idlist_get_channel_by_id
20 * Added cross reference of the joined channels to the
21 SilcClientEntry, and changed the SilcChannelEntry's
22 users list to SilcHashTable. The affected files are
23 lib/silcclient/idlist.[ch].
25 * Fixed a bug in hash table tarversing. While the hash table
26 is traversed with SilcHashTableList the table must not be
27 rehashed. It is now guaranteed that auto rehashable tables
28 are not rehashed while tarversing the list. Also defined that
29 silc_hash_table_rehash must not be called while tarversing
30 the table. Added function silc_hash_table_list_reset that must
31 be called after the tarversing is over. The affected files are
32 lib/silcutil/silchashtable.[ch].
34 * Changed all hash table traversing to call the new
35 silc_hash_table_list_reset in server and in client library.
37 * Added function silc_client_on_channel to return the
38 SilcChannelUser entry if the specified client entry is joined
39 on the specified channel. This is exported to application as
40 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
42 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
44 * Fixed founder regaining problem with JOIN command on normal
45 server. The notify for mode change must be sent always and
46 not only if !cmd->pending. Affected file silcd/command.c.
48 * Fixed the WHOWAS command's reply sending to support the
49 lists correctly. Affected file silcd/command.c.
51 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
53 * When sending JOIN command to router for processing the
54 sender's old command identifier was not saved back to the
55 sender's command context, fixed now. The affected file is
58 * Create the key in JOIN command of the router did not return
59 the channel key, added check for this. Affected file is
62 * Fixed a channel ID update bug in JOIN command reply. Do
63 not directly upgrade the ID but call the function
64 silc_idlist_replace_channel_id if the ID was changed.
65 Affected file silcd/command_reply.c.
67 * Fixed memory leaks from command calling if it would fail.
68 Affected file silcd/command.c.
70 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
72 * Applied patches from cras:
74 Memory leak fixes around libaries, irssi window resize fix,
75 new silclist.h and silcdlist.h, all extern inline changed to
78 * Removed dotconf from lib/dotconf, not needed anymore.
80 * Removed TRQ from lib/trq, not needed anymore.
82 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
83 with server connections. Later this will be configurable
84 in config file after new config file is done. Affected file
87 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
89 * Fixed a crash in server related to channel announcements.
90 Affected file silcd/server.c.
92 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
94 * Fixed memory leaks in silc_server_create_new_channel*
95 functions. Affected file silcd/server.c.
97 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
98 which ID was changed. This way the router will send the
99 user list for the channel again, and server won't be in
100 desync in some rare circumstances. Affected file is
101 silcd/packet_receive.c.
103 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
105 * Check for NULL socket pointer in the function
106 silc_server_packet_send_to_channel_real. Affected file
109 * Fixed the BAN notify handling to correctly remove ban
110 list. Affected file silcd/packet_receive.c.
112 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
114 * Fixed some header addition to Toolkit distribution in
115 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
117 * Added lib/silcclient/client_ops_example.h as an template
118 file for application programmers to quickly start using
119 the SilcClientOperation functions in their application.
120 Updated the lib/silcclient/README as well to tell about this
121 nice file made available.
123 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
125 * Call silc_server_remove_from_channels when removing client
126 entry when NO_SUCH_CLIENT_ID was received. Affected file
127 is silcd/command_reply.c.
129 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
131 * Added server & router operator statistics updating. Affected
132 file silcd/packet_receive.c and silcd/command.c.
134 * Fixed the SERVER_SIGNOFF notify handling on normal server
135 not to save the history information for clients. Same was
136 fixed earlier in remove_clients_by_server function, but not
137 here. Affected file silcd/packet_receive.c.
139 * Raised the default connection-retry count from 4 to 7 in
140 server. Affected file silcd/server.h.
142 * Cancel any possible reconnect timeouts when we start the
143 key exchange. Affected file silcd/server.c.
145 * Do not reconnect on connection failure when SCONNECT was
146 given. Affected files silcd/server.[ch].
148 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
150 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
152 * Fixed the NICK command to always give the unformatted
153 nickname to the one giving the NICK command. If unformatted
154 nickname is cached already it will be formatted and the
155 local entry will always get the unformatted nickname.
156 Affected file lib/silcclient/idlist.c.
158 * Fixed some double frees from client library commands.
159 Affected file is lib/silcclient/command.c.
161 * Fixed CUMODE command in server to assure that no one can
162 change founder's mode than the founder itself, there was a
163 little bug. Affected file silcd/command.c.
165 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
167 * Removed the SilcClientCommandDestructor from the client
168 libary, it is not needed anymore. Affected files are
169 lib/silcclient/silcapi.h, command[_reply].[ch],
170 client_notify, idlist.c.
172 * Fixed GETKEY command to first resolve client, and then
173 resolve the server only if the client was not found, instead
174 of resolving both at the same time. Affected file is
175 lib/silcclient/command.c.
177 * Added silc_client_start_key_exchange_cb and lookup the
178 remote hostname and IP address before starting the key
179 exchange with server. The affected file is
180 lib/silcclient/client.c.
182 * The server's public key is now saved using the IP address
183 of the server and not the servername for the filename.
184 The hostname public key filename is checked as an fall back
185 method if the IP address based filename is not found.
187 Fixed the GETKEY command to save the fetched server key
190 Print the remote server's hostname now when new key is
191 received during connection process. Affected file is
192 irssi/src/silc/core/client_ops.c.
194 * Return always our own public key to the client if it asks
195 for it with GETKEY command. Affected file silcd/command.c.
197 * Removed the use_auto_addr variable from default config
198 file since it was in wrong section. Affected file is
201 * Fixed TOPIC_CHANGE notification to not route it when it
202 was sent using silc_server_send_notify_to_channel function.
203 Affected file silcd/command.c.
205 * Fixed silc_server_send_notify_kicked to send the kicker's
206 Client ID also, it was missing. Affected files are
207 silcd/command.c, silcd/packet_send.[ch].
209 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
211 * Do not save client history information in SERVER_SIGNOFF.
212 Fixes the bug in normal server that it does not detect
213 the client becoming valid after the server becomes back
214 online. Affected file silcd/server_util.c.
216 * Added `sock_error' field into the SilcSocketConnection
217 context. When error occurs during socket operation (read
218 or write) the error is saved. Added also new function
219 silc_socket_get_error to return human readable socket error
220 message. Affected files are lib/silcutil/silcsockconn.[ch],
221 lib/silcutil/unix/silcunixsockconn.c, and
222 lib/silcutil/win32/silcwin32sockconn.c.
224 * The server now prints the socket error message in the
225 signoff for client. Affected file silcd/server.c.
227 * Fixed the `created' channel information sending from router
228 to server in JOIN command. Checks now whether the channel
229 really was created or not and set it according that.
231 Fixed the JOIN command to use the client entry's current
232 ID during the joining procedure instead of the one it sent
233 in the command (it is checked though), since it can change
234 between the packet processing and command processing, and
235 would just case unnecessary pain in the client end. Affected
236 file silcd/command.c.
238 * Fixed a channel key payload sending to use correct channel
239 ID when the server was forced to change the channel's ID by
240 router. Router sent the key payload with the old Channel ID.
241 Affected file silcd/packet_receive.c.
243 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
245 * Call silc_server_save_channel_key only if the key payload
246 was provided in the JOIN command's command reply. Affected
247 file silcd/command_reply.c.
249 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
251 * Fixed silc_mp_sizeinbase to return the value correctly with
252 MPI. Affected file lib/silcmath/mp_mpi.c.
254 * Fixed the stop_server signal to correctly stop the scheduler
255 and gracefully stop the server when SIGTERM or SIGINT signals
256 are received. Affected file silcd/silcd.c.
258 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
260 * Simple handling of TERM and HUP signals. Also added some log
261 flushing call around. Affected file is
264 * Fixed small bugs in silclog.c. Now buffering output will take
265 effect after 10 seconds since startup: This will ensure that
266 no important startup messages are lost. Also output redirection
267 will preserve original format ([Date] [Type] message).
268 Affected file is lib/silcutil/silclog.c.
270 * Added two options to the config file, in the logging section:
271 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
272 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
274 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
276 * Do not print the warning about log files not being initialized
277 more than once to avoid excess logging. Affected file is
278 lib/silcutil/silclog.c.
280 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
281 the SIM copying in make install in Makefile.am.pre.
283 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
285 * Rewritten silclog APIs. Globally interesting changes follows:
286 silc_log_set_files() changed to silc_log_set_file().
287 silc_log_set_callbacks() changed to silc_log_set_callback().
288 ROBOdoc documented silclog header file.
289 SilcLogCb now returns bool to wether inihibit the default
290 handler or not (to keep the old behaviour return always TRUE).
291 The new APIs should also fix the problem of the
292 silcd_error.log file that was written in the current directory.
295 Log files streams will remain opened after silc_log_set_file()
296 call, means less CPU usage notably on high traffic servers.
297 File streams are now full buffered, and flushed to the disk
298 every 5 minutes, lesses HD activity and CPU usage.
299 Messages can be redirected, allowing admins to configure
300 one single logfile for all server messages.
301 the silc_log_quick global variable to activate fast-logging.
302 Affected files lib/silcutil/silclog.[ch]
304 * Changed some code to conform new silclog APIs. Affected
305 files are doc/example_silcd.conf.in, silcd/server.c
306 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
309 * Fixed a memory leak that could occur in some situations.
310 Affected file silcd/serverconfig.c.
312 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
314 * Added the silc_client_del_client to remove the client from
315 all channels as well. Affected file lib/silcclient/idlist.c.
317 * Fixed the client library to correctly remove the client
318 from all channels when the client entry is being destroyed.
319 Affected file lib/silcclient/client_notify.c, command.c.
321 * Added auto-nicking support to the client library. If the
322 applicatio now sets client->nickname it will be sent to the
323 server after connecting by the library. This way for example
324 SILCNICK (or IRCNICK) environment variables will have effect
325 and always change the nickname automatically to whatever
326 it is wanted. Affected file lib/silcclient/client.[ch].
328 * Renamed silc_server_command_bad_chars to the
329 silc_server_name_bad_chars and moved it to the
330 silcd/server_util.[ch]. Added also new function
331 silc_server_name_modify_bad to return nickname that
332 includes bad characters as new nickname without those
333 bad characters. This check and modify is now used in
334 silc_server_new_client when the username is initially set
335 as nickname, so it must be checked to be valid nickname.
336 Affected file silcd/packet_receive.c.
338 * The nickname length is now taken from the packet for real
339 and not trusted to strlen() since it clearly can return
340 wrong length for nickname including bad characters. This
341 also applies to channel names. Affected file silcd/command.c.
343 * Removed the lib/silcsilm/modules directory. Modules are now
344 compiled into the lib/silcsim. Fixed the copying of the
345 modules to follow symbolic links in Makefile.am.pre.
347 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
349 * Fixed silc_string_regexify list creation. Fixes bugs with
350 BAN and INVITE commands in server. The affected file is
351 lib/silcutil/unix/silcunixutil.c.
353 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
355 * Removed the command destructor entirely from the server's
356 command and command reply routines. It is not needed, and
357 its usage was buggy and caused crashes. Affected files are
358 silcd/command[_reply].[ch].
360 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
362 * Cancel protocol and NULL sock->protocol if timeout
363 occurred during protocol. Affected file silcd/server.c.
365 * Cancel protocol timeouts always before calling the final
366 callback, to assure that after final callback is called
367 no other state will be called for the protocol anymore.
368 Affected file silcd/protocol.c.
370 * Print error log if incoming connection configuration could
371 not be found. Affected file silcd/server.c.
373 * Fixed JOIN command to correctly save the founder mode
374 to the client on normal SILC server, when the channel
375 was created by the router. Affected file silcd/command.c.
377 * Fixed LIST command (hopefully) to send correct reply
378 packets. Affected file silcd/command.c.
380 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
382 * The silc_packet_receive_process now returns FALSE if the
383 read data was invalid packet, and TRUE if it was ok.
385 The server now checks that if unauthenticated connection
386 sends data and its processing fails the server will close
387 the connection since it could be a malicious flooder.
389 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
391 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
393 * Make sure the warning about error opening a log file is
394 printed only once and not everytime it fails (produces
395 too much useless log). Affected file lib/silcutil/silclog.c.
397 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
399 * Made the silc_server_daemonise() function more readable.
400 Affected file silcd/server.c.
402 * Pid file is now optional, the user may comment it out from
403 the config file. Removed define SILC_SERVER_PID_FILE, we
404 don't need a default any longer. Affected file
405 configure.in.pre, lib/Makefile.am.pre.
407 * Make some use of the pid file. The server now dies at startup
408 if it detects a valid pid file on his path. The server would
409 die anyway in this circumstance, because of the bind() failure.
410 Affected file silcd/silcd.c.
412 * No longer compiling lib/dotconf.
414 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
416 * Fixed JOIN command parsing not to crash. Affected file
417 lib/silcclient/command.c.
419 * Fied the NICK_CHANGE notify to add the new client entry
420 even it is resolved. This removes an <[unknown]> nick
421 thingy bug in the client. Affected file is
422 lib/silcclient/client_notify.c.
424 * Do not try to allocate 0 bytes (efence does not like it)
425 in lib/silccore/silccomand.c when encoding payload.
427 * Do not take IRCNICK as nickname in Irssi SILC client since
428 it is not possible to set nickname before hand connecting
429 the server (TODO has an entry about adding auto-nicking
432 * Changed the silc_server_command_pending to check whether
433 there already exists an pending entry with the specified
434 command, command identifier and pending callback. This is
435 to fix IDENTIFY and WHOIS related crashes that may register
436 multiple pending commands with same identifier. Affected
437 file silcd/command.c.
439 * Fixed the server to reconnect to the router even if it
440 was already reconnecting and EOF was received. This to
441 fix a possibility that the server wouldn't ever try to
442 auto-reconnect to the router. Affected file silcd/server.c.
444 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
446 * Fixed the server's password authentication to use the
447 length of the locally saved password, and not the one
448 sent in the packet. Affected file silcd/protocol.c.
450 * Fixed same password authentication problem in the
451 Authentication Payload handling routines in
452 lib/silccore/silcauth.c.
454 * Yet another password authentication problem fixed with
455 channel password handling in silcd/command.c.
457 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
459 * If first character of string in silc_parse_userfqdn is '@'
460 then do not parse it. Affected file is
461 lib/silcutil/silcutil.c.
463 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
465 * Fixed minor bug in IDENTIFY command reply sending, which
466 caused various weird problems during JOIN when it was
467 resolving names for users. Affected file silcd/command.c.
469 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
471 * Fixed the IDENTIFY command reply sending to chech better valid
472 clients. It was possible to send incomplete list of replies.
473 Affected file silcd/command.c.
475 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
477 * Added silc_client_command[s]_[un]register functions now to
478 dynamically register the commands in client library. Removed
479 the static table of commands. This allows the client library
480 to call commands without causing the application to know about
481 what commands library has called.
483 Removed the INFO command reply kludge to detect when the command
484 was called by library. Now library use its own command reply
485 function for INFO command.
487 Added function silc_client_command_call to call a command.
488 Application can use it to call command, not access the structure
491 Now all commands that are sent by the client library (not
492 explicitly sent by application) use own command reply functions.
494 Affected files around lib/silcclient/ and in
495 irssi/src/silc/core/.
497 * Fixed the WHOIS command reply sending to chech better valid
498 clients. It was possible to send incomplete list of replies.
500 Fixed the WHOIS and IDENTIFY to send the request to router
501 if normal server did not do it and did not find any results.
503 Affected file silcd/command.c.
505 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
507 * Moved the internal data from SilcClient context into its
508 own file, not accesible to application. Affected files
509 lib/silcclient/client.h and lib/silcclient/client_internal.h,
510 and other files in client library.
512 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
514 * Added doc/examples installation target in Makefile.am.pre.
517 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
519 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
520 commands the found client entry will be removed from the
521 cache, after notifying application about the error. Affected
522 file lib/silcclient/command_reply.c.
524 * Changed the /MSG to check for exact nickname user gave, and
525 not let `nick' match `nick@host' if it is only one found. Now,
526 user must type the exact nickname (like nick@host2) even if
527 there are no more than one same nicks found. This is to avoid
528 a possibility of sending nickname to wrong nickname since
529 `nick' could match `nick@host'. Affected file is
530 irssi/src/core/silc-servers.c.
532 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
534 * Do not print "you are now server operator" or similar when
535 giving /away command. Affected files are
536 irssi/src/silc/core/client_ops.c, silc-servers.h.
538 * Made the silc_server_command_pending_error_check to send
539 the same command reply payload it received back to the
540 original sender of the command. This way all arguments
541 that was received by the server will be received by the
542 client too. Affected file silcd/command.c.
544 * Added the silc_idcache_add to return the created cache entry
545 to a pointer. Affected file lib/silccore/silcidcache.[ch].
547 * Add global clients to expire if they are not on any channel.
548 This is because normal server will never know if they signoff
549 if they are not on any channel. The cache expiry will take
550 case of these entries. This is done by normal servers only.
551 The affected files are silcd/command_reply.c,
552 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
554 * If server receives invalid ID notification for WHOIS or
555 IDENTIFY and the ID exists in the lists, it is removed.
556 Affected file silcd/command_reply.c.
558 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
559 in client then client entry that it matches is searched and
560 the nickname is printed on the screen for user. Affected
561 file irssi/src/silc/core/client_ops.c.
563 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
565 * Use cache entry expire time in the LIST command reply to
566 purge old entries from the cache after the LIST command
567 reply has been received. This way we don't have non-existent
568 entries in the cache for too long. Affected file is
569 silcd/command_reply.c.
571 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
573 * If we are normal server, and we've not resolved client info
574 in WHOIS or IDENTIFY from router, and it is global client,
575 we'll check whether it is on some channel. If it is not
576 then we cannot be sure about its validity and will resolve it
577 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
578 file silcd/command.c.
580 * Search channel by name (if possible) rather than by ID
581 in IDENTIFY command's command reply. Affected file is
582 silcd/command_reply.c.
584 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
586 * Distribute to the channel passphrase in CMODE_CHANGE notify.
587 Updated specs and implemented it. Affected file silcd/command.c,
588 silcd/packet_send.c and silcd/packet_receive.c.
590 * Implemented the <founder auth> payload handling in the JOIN
591 command. If provided all conditions for channel joining
592 except requirement to provide correct passphrase can be
593 overrided by the channel founder. Updated the protocol specs.
594 Affected file silcd/command.c.
596 Added support for founder auth in JOIN command in client
597 library. Fixed the parsing of the JOIN command now to support
598 all options as they should be. The affected file is
599 lib/silcclient/command.c.
601 * Optimized the WHOIS and IDENTIFY commands to send the request
602 to router only if it includes nicknames or other names. If
603 they include only IDs then check the local cache first before
604 routing. Affected file is silcd/command.c.
606 * Added channels topic announcements. Affected file is
607 silcd/packet_receive.c and silcd/server.c.
609 * Fixed the silc_server_send_notify_topic_set to really destine
610 the packet to channel. Affected file silcd/packet_send.c.
612 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
613 library. Affected file lib/silcclient/client_notify.c.
615 * Added UMODE announcements. Affected file silcd/server.c.
617 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>

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

668 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
669 routines. Added silc_net_is_ip[4/6]. Affected file is
670 lib/silcutil/unix/silcunixnet.c. All routines that take
671 address as argument now supports both IPv4 and IPv6 addresses.
673 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
675 * Fixed LIST command reply sending in server. Affected file
678 * Server now sends the kicker's client ID in the KICK notify
679 to the kicked client. Affected file silcd/command.c.
681 * The client library now parses the kickers client ID and
682 UI displays it. Affected files lib/silcclient/client_notify.c
683 and irssi/src/silc/core/silc-channels.c, module-formats.c.
685 * Made all payload parsing function prototypes consistent.
686 They all take now const unsigned char * and uint32 pair as
687 the payload data instead of SilcBuffer. Changes all around
688 the source tree. Other unsigned char* -> const unsigned char*
689 changes around the tree as well.
691 * Optimized SFTP client and server packet sending not to
692 allocate new buffer for each packet but to recycle the
693 first allocated buffer. Affected files are
694 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
696 * Optimized the SFTP client to use SilcList instead of
697 SilcDList for requests, because it is faster. Affected file
698 is lib/silcsftp/sftp_client.c.
700 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
701 into lib/silccore/silcid.[ch].
703 Renamed silcpayload.[ch] into silcargument.[ch].
705 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
707 * If client entry is deleted with active key agreement
708 session, abort the session.
710 The silc_client_abort_key_agreement now calls the completion
711 callback with new SILC_KEY_AGREEMENT_ABORTED status.
713 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
716 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
718 * Don't use __restrict in older GCC's. Affected file is
719 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
721 * silc_net_localhost now attempts to reverse lookup the
722 IP/hostname. Affected file lib/silcutil/silcnet.c.
724 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
725 command. It can be used to gain founder privileges at
726 the same time when joining the channel.
728 Defined that the SILC_NOTIFY_TYPE_KICKED send the
729 kicker's client ID as well. Updated protocol specs.
731 Defined that the server must send SILC_COMMAND_IDENTIFY
732 command reply with error status to client who sent
733 private message with invalid client ID.
735 Updated the protocol specification.
737 * Added silc_server_send_command_reply to send any
738 command reply. Affected file silcd/packet_send.[ch].
740 * Added silc_id_payload_encode_data to encode ID payload
741 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
743 * The server now send IDENTIFY command reply with error
744 status if client ID in private message is invalid. Affected
745 file silcd/packet_receive.c.
747 * Save the server key file with server's IP address in
748 the filename instead of hostname. The affected file is
749 irssi/src/silc/core/client_ops.c.
751 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
753 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
756 * Added libtool support for compiling shared objects in
757 lib/silcsim. Affected file configure.in.pre and
758 lib/silcsim/Makefile.am. Original patch by cras.
760 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
762 * Pid file configuration, and server's config file fixes
763 patch by toma. Updated CREDITS file.
765 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
767 * Fixed silc_client_channel_message to not try to decrypt
768 the message twice if it resolved the destination client
769 information. This could cause of dropping one channel
770 message. Affected file lib/silcclient/client_channel.c.
772 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
774 * Added silc_client_run_one into lib/silcclient/silcapi.h and
775 lib/silcclient/client.c. This function is used when the SILC
776 Client is run under some other scheduler, or event loop or
777 main loop. On GUI applications, for example this may be
778 desired to used to run the client under the GUI application's
779 main loop. Typically the GUI application would register an
780 idle task that calls this function multiple times in a second
781 to quickly process the SILC specific data.
783 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
785 * Fixed silc_server_drop() for dropping the supplementary
786 groups as well, this could cause a security hole on some
789 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
791 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
794 * Write PID file after dropping privileges. Added -F option
795 to run server on foreground. A patch by debolaz.
796 Affected files silcd/server.c, silcd/silcd.c.
798 * Fixed MOTD to return the MOTD file server name. Affected
799 file silcd/command.c.
801 * Added INFO command reply handling to the Irssi SILC Client.
802 Affected file irssi/src/silc/core/client_ops.c.
804 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
806 * Fixed the silc_idcache_list_* routines to really support
807 the dynamic list. Fixes a crash. Affected file is
808 lib/silccore/silcidcache.c.
810 * Fixed the LIST command reply to really call LIST command's
811 pending callbacks. Affected file silcd/command_reply.c.
813 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
815 * Update conn->local_entry->nickname after giving NICK
816 command. Affected file lib/silcclient/command.c.
818 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
820 * Added the [pid] option to the silcd configuration file
822 Affected files: serverconfig.[ch] and silcd.c
824 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
826 * Save fingerprint in WHOIS command reply in server.
827 Affected file silcd/command_reply.c.
829 * Fixed NICK commands pending callback registration.
830 Affected file lib/silcclient/command.c.
832 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
834 * Use ++server->cmd_ident when sending commands in server,
835 instead of random number. Affected file silcd/command.c.
837 * Fixed GETKEY command reply to call actually GETKEY pending
838 command callbacks. Affected file silcd/command_reply.c.
840 * A bit stricter check for nicknames. Check for same nickname
841 in NICK command also. Affected file silcd/command.c.
843 * Do not call INFO command everytime client ID changes, only
844 during first connecting. Affected file lib/silcclient/client.c.
846 * Set the new nickname only after successful command reply for
847 NICK command is returned by server. Affected file
848 lib/silcclient/command.c.
850 * Remove nicknames from nicklist during server_signoff notify.
851 Should fix /NAMES bit more. The affected file is
852 irssi/src/silc/core/silc-channels.c.
854 * Added `fingerprint' field to the SilcIDListData in the
855 silcd/idlist.h to hold the fingerprint of the client's
858 Send the fingerprint of the client's public key in WHOIS
861 Affected files silcd/command.c, and silcd/idlist.[ch].
863 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
864 create fingerprint from given data.
866 * Show the fingerprint of the client's public key in WHOIS.
867 Affected files irssi/src/module-formats.[ch] and
868 irssi/src/silc/core/client_ops.c.
870 * Format the multiple same nicknames also during JOIN and
871 NICK_CHANGE notifys. Affected file is
872 lib/silcclient/client_notify.c.
874 * Do not print error on screen for invalid private message
875 payload since it can come if someone is sending private
876 messages with wrong key. Affected file
877 lib/silccore/silcprivate.c.
879 * Fixed multiple concurrent /PING crash. Affected file
880 lib/silcclient/command.c.
882 * Changed the wrong ID encoding. All IP addresses must be
883 in MSB first order in encoded format. They were encoded
884 wrong and was in LSB format. Affected files are
885 silcd/serverid.c, lib/silcutil/silcutil.c.
887 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
889 * Call the `connect' client operation through the scheduler
890 in case of error. Affected file lib/silcclient/client.c.
892 * Call the `failure' client operation even if the error
893 occurred locally during a protocol. Affected file is
894 lib/silcclient/protocol.c.
896 * Added support of sending LIST command to router from normal
897 server. This way normal server can get list of all channels
898 in the network too. Fixed the channel list sending in the
899 server too. Affected files are silcd/command.c, and
900 silcd/command_reply.[ch].
902 * Added silc_server_update_channels_by_server and
903 silc_server_remove_channels_by_server. They are used during
904 disconnection of primary router and in backup router protocol.
905 Affected file silcd/server_util.[ch], silcd/server.c and
906 silcd/server_backup.c.
908 * Fixed channel adding to global list in IDENTIFY command
909 reply in server. Affected file silcd/command_reply.c.
911 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
913 * If the incoming packet type is REKEY or REKEY_DONE process
914 that packet always synchronously. Fixes yet another MAC
915 failed error on slow (dialup) connections. Affected file
916 lib/silcclient/client.c and silcd/server.c.
918 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
920 * Call check_version SKE callback for initiator too. Affected
921 file lib/silcske/silcske.c.
923 * Implemented fix for security hole found in the SKE that was
924 fixed in the specification few days back; the initiator's
925 public key is now added to the HASH value computation.
926 Added backwards support for the old way of doing it too, for
927 old clients and old servers. Affected file is
928 lib/silcske/silcske.c.
930 * Enabled mutual authentication by default in SKE. If initiator
931 is not providing mutual authentication the responder will
932 force it. This will provide the proof of posession of the
933 private key for responder. The affected files are
934 lib/silcclient/protocol.c and silcd/protocol.c.
936 * Do not cache anymore the server's public key during SKE.
937 We do mutual authentication so the proof of posession of
938 private key is done, and if the server is authenticated in
939 conn auth protocol with public key we must have the public
940 key already. Affected file silcd/protocol.c.
942 * Added new global debug variable: silc_debug_hexdump. If
943 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
944 file lib/silcutil/silclog.[ch].
946 * Fixed compilation warning due to char * -> const char *.
947 Affected files lib/silcutil/silcnet.h, and
948 lib/silccore/silcauth.[ch].
950 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
952 * Fixed CMODE command when new channel key was created. If
953 the creation failed the old key was removed. Next time giving
954 same command would crash the server since the old key was
955 freed already. Affected file silcd/command.c.
957 * Fixed the silc_server_announce_get_channels to not crash
958 on reconnect. Affected file silcd/server.c.
960 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
962 * Added silc_log_set_debug_string function to set a regex
963 string to match for debug output. Only the function names,
964 or filenames matching the given debug string is actually
965 printed. This way it is possible to filter out those debug
966 strings that user is not interested in.
968 Fixed a bug in silc_string_regexify.
970 Affected files lib/silcutil/silclog.[ch], and
971 lib/silcutil/unix/silcunixutil.c.
973 * Changed the -d options in both server and Irssi SILC client
974 to take the debug string as argument. Affected files
975 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
977 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
979 * Added silc_hash_babbleprint to create a Bubble Babble
980 Encoded fingerprint. The encoding is developed by Antti
981 Huima (draft-huima-babble-01.txt), and it creates human
982 readable strings out of binary data. Affected file
983 lib/silccrypt/silchash.[ch].
985 * Print the babble print now in addition of fingerprint as well
986 in Irssi SILC client. Affected files are
987 irssi/src/fe-common/silc/module-formats.[ch],
988 irssi/src/fe-common/silc/core/client_ops.c.
990 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
992 * Fixed a security problem found in SKE. The initiator's
993 public key too is now added to the HASH hash value creation
994 which is signed by the responder to create the SIGN value.
995 This will prevent anyone in the middle to lie to the responder
996 about the initiator's public key. If this is done now, the
997 man in the middle will get caught. Updated the protocol
1000 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1002 * Better installation directory handling. Configure module
1003 paths and other paths automatically to example_silc* files
1004 in doc/. A patch by toma.
1006 * Fixed compiler warning from MPI library, and from SILC RNG.
1009 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1010 It can be configured with ./configure. A patch by toma.
1012 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1014 * Find correct make to use in prepare-clean. A patch by
1015 toma. Affected file prepare-clean.
1017 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1019 * Added irssi variables use_auto_addr, auto_bind_ip,
1020 auto_bind_port and auto_public_ip.
1022 * Changed the interface for silc_client_send_key_agreement
1023 in lib/silcclient/silcapi.h
1027 irssi/src/silc/core/silc-core.c
1029 lib/silcclient/silcapi.h
1030 irssi/src/silc/core/silc-channels.c
1031 lib/silcclient/client_keyagr.c
1034 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1036 * Added silc_pkcs_public_key_compare to compare two
1037 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1039 * Check that the client who set the founder mode on the
1040 channel is the same client that is giving the founder
1041 mode to itself. It is done by comparing the saved public
1042 key (it is saved even in the authentication is passphrase).
1043 Affected file silcd/command.c.
1045 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1047 * Do not process packet for disconnected socket connection.
1048 Affected file lib/silccore/silcpacket.c.
1050 * Process the DISCONNECT packet through scheduler in the
1051 client library. Affected file lib/silcclient/client.c.
1053 * Fixed the silc_client_packet_parse to not to increase
1054 the packet sequence number if the conn->sock and the
1055 current socket connection is not same. This can happen
1056 for example during key agreement when the conn includes
1057 multiple socket connections (listeners). Affected file
1058 lib/silcclient/client.c.
1060 * The sender of the file transfer request now provides also
1061 the pointer (listener) for the key exchange protocol. If
1062 the listener cannot be created then it sends empty key
1063 agreement and lets the receiver provide the listener.
1065 Added `local_ip' and `local_port' arguments to the
1066 silc_client_file_send. If they are provided they are used,
1067 if not then it will attempt to find local IP address, if
1068 not found or bind fails then the remote client will provide
1071 Affected files are lib/silcclient/client_ftp.c and
1072 lib/silcclient/silcapi.h.
1074 * Extended the FILE SEND command to support defining the
1075 local IP and port for key exchange listener. They are
1076 optional. Affected file irssi/src/silc/core/silc-servers.c.
1078 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1080 * Defined to WHOIS command reply the sending of fingerprint
1081 of the client's public key (if the proof of posession of the
1082 corresponding private key is verified by the server).
1083 Updated to the protocol specification.
1085 * Added support of receiving the client's public key's
1086 fingerprint in command reply in client library. Affected
1087 file is lib/silcclient/command_reply.c, and
1088 lib/silcclient/idlist.[ch].
1090 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1092 * Do not send over 128 chars long nickname to the server
1093 in NICK command. Affected file lib/silcclient/command.c.
1095 * Do not send over 256 chars long channel names to the server
1096 in JOIN command. Affected file lib/silcclient/command.c.
1098 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1100 * Assure that silc_server_close_connection cannot be called
1101 twice for same socket context. Affected file is
1104 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1106 * Send error message to application if opening file for
1107 writing during file transfer fails. Affected file is
1108 lib/silcclient/client_ftp.c.
1110 Remove all file transfer sessions for a client that we're
1111 removing from ID cache.
1113 Affected file is lib/silcclient/client_ftp.c.
1115 * Fixed silc_net_addr2bin to return correct address. Affected
1116 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1118 * Fixed file transfer session removing on signoff notify.
1119 Affected file irssi/src/silc/core/silc-servers.c.
1121 * Added the SilcClientFileError to be returned in the monitor
1122 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.

1143 client library. Affected file lib/silcclient/client_prvmsg.c.
1145 * Do not actually remove the client directly from ID cache
1146 during SERVER_SIGNOFF, but invalidate it. This way we
1147 preserve the WHOWAS info for the client. Affected file
1148 silcd/server_util.c.
1150 * Fixed SERVER_SIGNOFF notify handling in the server. The
1151 server is now able to process incoming SERVER_SIGNOFF notify
1152 for a server that it doesn't even know about. It will remove
1153 the clients provided in the notify. Affected file
1154 silcd/packet_receive.c.
1156 * Check for partial packet in data queue after every packet that
1157 was found from the queue. Return and wait for more data if
1158 there is partial data in queue. Affected file is
1159 lib/silccore/silcpacket.c.
1161 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1172 * Added better monitor of file transfers. It now monitors
1173 key agreement protocol during the file transfer too. Added
1174 error reporting too. Affected files
1175 irssi/src/silc/core/silc-servers.c,
1176 irssi/src/fe-common/silc/module-formats.[ch].
1178 * Wrote a help file for FILE command.
1180 * Added silc_rng_global_get_byte_fast to get not-so-secure
1181 random data as fast as possible. Random data is read from
1182 /dev/urandom if available and from the SILC RNG if not
1183 available. It is used in padding generation. Affected file
1184 lib/silccrypt/silcrng.[ch].
1186 * All packets in client library are now processed synchronously.
1187 Optimized packet processing a lot. Affected file
1188 lib/silcclient/client.c.
1190 * All server connection packets are processing synchronously
1191 now in server, to optimize packet processing. Affected file
1194 * Include files are installed now only in Toolkit distribution
1195 if make install is given. Affected files: all Makefile.am's.
1197 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1199 * Assure that silc_client_notify_by_server_resolve does not
1200 resolve the client information multiple times. If it cannot
1201 be found by the first it cannot be found at all. Affected
1202 file lib/silcclient/client_notify.c.
1204 * Fixed WHOWAS command reply calling. Affected file
1205 lib/silcclient/command_reply.c.
1207 * Removed all references to silc_idlist_get_client from the
1208 Irssi SILC client since that call is internal call used by
1209 the library. The Irssi SILC client will use now client
1210 retrieval functions found in silcapi.h.
1212 * Fixed a bug in resolving nickname info before sending
1213 private message. It used freed memory. Affected file
1214 irssi/src/silc/core/silc-servers.c.
1216 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1218 * Assure my_channels statistics cannot go negative in server.
1219 Affected files silcd/server.c, silcd/server_util.c.
1221 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1235 * Added silc_net_localip to return local host's IP address.
1236 Affected file lib/silcutil/silcnet.[ch].
1238 * If key exchange or rekey protocol is active for a connection
1239 parse all packets syncronously since there might be packets
1240 in packet queue that we are not able to process without first
1241 processing packets before them. Affected file silcd/server,
1242 lib/silcclient/client.c.
1244 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1245 whether library should continue processing the packet.
1246 Affected file lib/silccore/silcpacket.h.

1277 lib/silcutil/silcutil.[ch].
1279 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1281 * Resolve the client info when received private message or
1282 channel message for a client which nickname we don't know.
1283 Affected files lib/silcclient/client_prvmsg.c and
1284 lib/silcclient/client_channel.c.

1292 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1293 is incomplete and is being resolved, it won't be resolved
1296 Make sure also that USERS command reply does not resolve
1297 twice information. Affected file is
1298 lib/silcclient/command_reply.c.
1300 Make sure that silc_client_get_clients_by_list does not
1301 resolve twice same information.
1303 * Check for valid client->id in the silc_server_free_client_data.
1304 Affected file silcd/server.c.
1306 * Fixed /GETKEY nick@server not to crash if the server entry
1307 is not found. Affected file lib/silcclient/command.c.
1309 * Fixed the silc_server_check_cmode_rights to check the
1310 requested modes correctly. Affected file silcd/command.c.

1315 Affected file silcd/command.c.
1317 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * Call the silc_server_udpate_servers_by_server in the
1320 primary router that comes back online in the backup resuming
1321 protocol. Otherwise it routes packets wrong. Affected file
1322 silcd/server_util.[ch], silcd/server_backup.c.
1324 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1326 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1327 lib/silcutil/silcbuffmt.[ch].
1329 * Redefined the SILC packet header to include the padding
1330 length. Affected file lib/silccore/silcpacket.[ch].
1332 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1333 length for maximum padding up to 128 bytes). Affected
1334 file lib/silccore/silcpacket.h.
1336 * Removed all backwards support for old 0.5.x MAC thingies.
1337 The SILC packet header change makes it impossible to be
1338 backwards compatible.
1340 * Send the ENDING packet with timeout in the backup resuming
1341 protocol. This is to assure that all routers has connected
1342 to the primary router. Affected file silcd/server_backup.c.
1344 * Changed the RNG to take the first IV from random data. It
1345 used to take it from zero actually. Changed the RNG also
1346 to use /dev/urandom during session. /dev/random is used
1347 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1349 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1351 * Changed the SILC packet header to have the first two bytes
1352 (the packet length) encrypted. Affected files aroung the
1353 code tree, lib/silccore/silcpacket.[ch]. Removed the
1354 SilcPacketCheckDecrypt callback. It is not needed anymore
1355 since the silc_packet_receive_process will determine now
1356 whether the packet is normal or special.
1358 * Implemented the unidirectional MAC keys. Affected files
1359 lib/silcske/silcske.c, silcd/protocol.c and
1360 lib/silcclient/protocol.c.
1362 * Implemented the packet sequence number to the MAC computation.
1363 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1364 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1365 lib/silcclient/protocol.c.
1367 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1369 * Allow backup router to announce servers. All servers
1370 announced by backup router are added to the global list
1371 automatically. Update hte server's socket to our primary
1372 router also when backup router announces a server.
1373 Affected file silcd/packet_receive.c.
1375 * Do not update the client->router in the function
1376 silc_server_udpate_clients_by_server if the client is on
1377 global list. We might fail to find any specific server
1378 for locally connected clients and local cell clients. They
1379 should still use the `from' and not `to' as client->router.
1380 This fixes backup router resuming protocol. Affected file
1381 silcd/server_util.c.
1383 * Decrease channel statistics count only if the channel
1384 deletion worked. Affected files are silcd/server.c and
1385 silcd/server_util.c.
1387 * Added silc_server_update_servers_by_server to update origin
1388 of all server entries. Used during backup router protocol.
1389 Affected files silcd/server_util.[ch], silcd/server.c. and
1390 silcd/backup_router.c.
1392 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1393 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1394 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1395 lib/silccrypt/silchmac.c.
1397 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1399 * Assure that router cannot reroute the same channel message
1400 to the sender. Affected file silcd/packet_receive.c.
1402 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1404 * Made better checks that the channel message is not sent
1405 to the router it came from. Affected file is
1406 silcd/packet_send.c. Fixed memory leak too.
1408 * Announce informations for incoming router connection, but
1409 only after checking if it is replaced by backup router.
1410 Affected file silcd/packet_receive.c.
1412 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1414 * Fixed the backup resuming protocol to work in multiple
1415 router environment. Affected file silcd/server_backup.c.
1417 * Route packet only to one router in the function
1418 silc_server_packet_send_to_channel. Affected file is
1419 silcd/packet_send.c.
1421 * Fixed silc_server_send_notify_dest to set the broadcast
1422 flag. Fixed the silc_server_send_notify_topic to actually
1423 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1424 Affected file silcd/packet_send.c.
1426 * Changed the SFTP Filesystem interface. Changed the
1427 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1428 the filesystem operation function. The SilcSFTPFilesystem
1429 is now a context that is allocated by all filesystem allocation
1430 functions and it already includes the operations structure
1431 and filesystem specific context. It is given as argument
1432 now to the silc_sftp_server_start. This made the interface
1433 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1434 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1436 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1438 * Changed the backup router adding and getting interfaces
1439 in the server. The router that will be replaced by the
1440 specified backup router is now sent as argument. Affected
1441 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1444 * Added silc_net_addr2bin_ne to return the binary form of
1445 the IP address in network byte order. Affected files
1446 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1448 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1450 * Check for existing server ID in silc_server_new_server
1451 and in silc_server_connect_to_router_final and remove the
1452 old entry if it exists. Affected file silcd/packet_receive.c,
1455 * Send the channel message always to only one router, either
1456 in upstream or downstream. Affected file is
1457 silcd/packet_send.c.
1459 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1461 * Wrote the definition of the backup resuming protocol to the
1462 protocol specification.
1464 * Removed one redundant channel key generation from normal
1465 server during joining procedure. Removed one redundant
1466 channel key sending from server to router during joining
1467 procedure. Affected file silcd/command.c.
1469 * Made minor bugfixes to the backup router resuming protocol.
1470 Affected file silcd/server_backup.c, server.c.
1472 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1474 * Added --disable-asm configuration option. Affected files
1475 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1478 * Implemented the backup resuming protocol that is used to
1479 resume the primary router position in the cell after the
1480 primary router comes back online. Affected files
1481 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1482 and silcd/server_util.[ch].
1484 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1486 * Sleep two (2) seconds after sending QUIT command to server.
1487 Affected file lib/silcclient/command.c.
1489 * Assure that if outgoing data buffer is pending do not force
1490 send any data. Affected file silcd/packet_send.c.
1492 * Assure that if outgoing data buffer is pending do not force
1493 send any data. Affected file lib/silcclient/client.c.
1495 * Implemented the backup router support when the primary router
1496 goes down. The servers and routers can now use the backup
1497 router as new primary router without loosing connectivity.
1499 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1501 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1502 in the server to indicate disabled entry. All data read
1503 from the connection will be ignored and no data is sent
1504 for entry that is disabled. Affected files are
1505 silcd/idlist.h, silcd/server.c.
1507 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1509 * Created SFTP client and server test programs in the
1510 lib/silcsftp/tests directory.
1512 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1514 * Implemented memory filesystem (virtual filesystem) for
1515 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1518 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1520 * Implemented the SFTP (SSH File Transfer Protocol) to the
1521 lib/silcsftp. It includes SFTP client and SFTP server
1524 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1526 * Moved lib/silccore/silcprotocol.[ch] to the
1527 lib/silcutil library.
1529 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1530 take variable argument list pointer as argument. Affected
1531 file lib/silcutil/silcbuffmt.[ch].
1533 * Added silc_buffer_set function that is used to set data
1534 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1535 Affected file lib/silcutil/silcbuffer.h.
1537 * Changed various routines in the core library to use the new
1538 silc_buffer_set instead of allocating new buffer only for
1541 * Added 64-bit value formatting and unformatting support to the
1542 silc_buffer_[un]format routines. Affected file is
1543 lib/silcutil/silcbuffmt.[ch].
1545 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1546 to includes/bitmove.h.
1548 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1550 * Fixed channel user mode saving in client library. Affected
1551 file lib/silcclient/command[_reply].c.
1553 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1555 * Defined the file transfer to the SILC Protocol. Added
1556 new packet type SILC_PACKET_FTP and defined File Transfer
1557 Payload. The mandatory file transfer protocol is SFTP
1558 (SSH File Transfer Protocol). Affected file in addition
1559 of the internet draft is lib/silccore/silcpacket.h.
1561 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1562 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1563 is used as part of backup router protocol when the primary
1564 router of the cell is back online and wishes to resume
1565 the position as primary router.
1567 * Redefined the MAC generation keys in the protocol. The
1568 same key is not used anymore in both direction. Both
1569 direction will now use different keys for sending and
1570 receiving. This fixes a potential security flaw. This
1571 change causes incompatibilities in the protocol.
1573 * Redefined also the MAC computation from the packet.
1574 An packet sequence number is now added to the MAC
1575 computation. This prevents possible replay attacks against
1576 the protocol. This change too causes incompatibilities
1579 Added `sequence' field to the SilcPacketContext to hold
1580 the current sequence number for the packet.
1582 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1584 * Added `created' field to the SilcIDListData in the file
1585 silcd/idlist.h to indicate the time when the entry was
1588 * Added `created' field to the SilcChannelEntry too. Affected
1589 file silcd/idlist.h.
1591 * Added `creation_time' aguments to all the announcement functions
1592 in the server. If it is provided then only the entries that
1593 was created after the provided time frame are actually
1594 announced. Affected file silcd/server.[ch].
1596 * The protocol says that the Channel ID's IP address must be
1597 based on the router's IP address. Added check for this in
1598 the silc_server_new_channel when processing incoming New Channel
1599 Payload. Affected file silcd/packet_receive.c.
1601 * Print out the correct version with --version in SILC client.
1602 Affected file irssi/src/silc/core/silc-core.c.
1604 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1606 * Fixed WHOWAS command to check for completnes of the client
1607 entry always, not just when the command is coming from client.
1608 Affected file silcd/command.c.
1610 * Added new function silc_server_packet_queue_purge to purge the
1611 outgoing data queue to the network. After the function returns
1612 it is guaranteed that the outgoing packet queue is empty.
1613 Affected file silcd/packet_send.[ch].
1615 * Purge the outgoing packet queue in the rekey protocol's final
1616 callback to assure that all rekey packets go to the network
1617 before quitting the protocol. Affected file silcd/server.c.
1619 * Added silc_client_packet_queue_parse as similar function as
1620 in server to the client library. The affected file is
1621 lib/silcclient/client.c.
1623 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1625 * Splitted silcd/server.c and created silcd/server_util.[ch]
1626 for utility functions.
1628 * Added new socket flag SILC_SF_DISABLED to indicate that the
1629 connection is open but nothing can be sent to or received from
1630 the connection. Affected file lib/silcutil/silsockconn.[ch].
1631 The checking for disabled socket is checked in the low level
1632 silc_socket_write and silc_socket_read functions.
1634 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1636 * Allow only nicknames and channel names that fits into the
1637 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1639 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1641 * When processing JOIN command reply in server check that if
1642 the channel exists in our global list we'll move it the local
1643 list. Affected file silcd/command_reply.c.
1645 * Fixed the check whether client is joined on the channel already
1646 in JOIN command. Affected file lib/silcclient/command.c.
1648 * Fixed the JOIN command reply to check whether the channel
1649 already exists. Affected file lib/silcclient/command_reply.c.
1651 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1653 * Added silc_ske_status_string to map the SKE error numbers
1654 to readable strings. The affected files are
1655 lib/silcske/silcske[_status].[ch].
1657 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1659 * Do not show the private channels on the WHOIS channel list
1660 as it is not allowed by the protocol. The affected file is
1663 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1665 * Assure that the packet length digged from the actual packet
1666 is something sensible in the silc_packet_decrypt_rest_special
1667 in lib/silccrypt/silcpacket.c.
1669 * Free and NULL the allocated pointer in silc_hmac_alloc if
1670 the HMAC allocation fails. The affected file is
1671 lib/silccrypt/silchmac.c.
1673 * Print the selected security properties to the log files in
1674 the server. Affected file silcd/protocol.c.
1676 * Add SKE's reference counter even if calling the completion
1677 callback manually. Otherwise it goes negative, although it
1678 does not cause any problems. The affected file is
1679 lib/silcske/silcske.c.
1681 * Remove the client entry with short timeout after giving the
1682 KILL command. Affected file lib/silcclient/command.c.
1684 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1685 case all found clients are already disconnected (WHOWAS would
1686 found them) in the server. Affected file silcd/command.c.
1688 * Update the last_receive (time of last data received) to be
1689 updated only when received private or channel message so that
1690 the idle time showed in WHOIS makes more sense.
1692 * Added boolean field `valid' in to the SilcClientEntry in the
1693 client library to indicate whether the entry is valid or not.
1694 This fixes the nickname change bug on channel when changing
1695 the nickname to be same than the old (like nick to Nick) the
1696 nickname formatter doesn't set the new nick anymore to Nick@host.
1697 Affected file lib/silcclient/idlist.[ch].
1699 * Now actually fixed the nickname changing on disconnection.
1700 Added new function silc_change_nick to the Irssi SILC Client.
1701 Affected file irssi/src/silc/core/client_ops.c,
1702 irssi/src/silc/core/silc-nicklist.[ch].
1704 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1706 * Check that the public key exists in the GETKEY command before
1707 trying to encode it. Affected file silcd/command.c.
1709 * Print some notifications on received public keys with GETKEY
1710 command in the Irssi SILC Client. Affected files are
1711 irssi/src/fe-common/silc/module-formats.[ch],
1712 irssi/src/silc/core/client_ops.c.
1714 * Use IDENTIFY command to resolve the server information in the
1715 GETKEY command instead of INFO command. Affected file
1716 lib/silcclient/command.c.
1718 * All command reply functions in the client library now calls
1719 the pending command reply callbacks even if an error has
1720 occurred. The server has done this a long time and now it was
1721 time to move the client library to this as well. Now all
1722 errors can be delivered back to the pending command reply
1723 callbacks if necessary. Affected files are
1724 lib/silcclient/command[_reply].[ch].
1726 * Change the nickname on disconnection back to the username
1727 because in reconnect the server will enforce it to it anyway.
1728 Affected file irssi/src/silc/core/silc-servers.c.
1730 * Fixed a config file parsing bug in the Irssi SILC client.
1731 Affected file irssi/src/silc/core/clientconfig.c.
1733 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1735 * When printing the channel mode on JOIN, verify that the
1736 channel key and channel's HMAC are valid. Affected file
1737 irssi/src/silc/core/client_ops.c.
1739 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1741 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1742 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1743 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1745 * Removed channel key rekey task deleting from the function
1746 silc_server_save_channel_key. Affected file silcd/server.c.
1747 Added explicit timeout task context instead that is used to
1748 delete the task if we are registering a new task before the
1749 new task has elapsed.
1751 * When channel key rekey occurs the client library now saves
1752 the old channel key for a short period of time (10 seconds) and
1753 is able to use it in case some is still sending channel
1754 messages encrypted with the old key after the rekey. Affected
1755 file lib/silcclient/[idlist.h|client_channel.c].
1757 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1759 * Added check to the silc_server_new_id_real to not accept
1760 new ID if it is the sender's own ID. Affected file is
1761 silcd/packet_receive.c.
1763 * Assure that we do not announce ourself or the one we've
1764 sending our announcements when we're router and are announcing
1765 servers to our primary router. Affected file silcd/server.c.
1767 * Fixed silc_server_command_identify_check_client to assemble
1768 correct WHOIS packet. It send corrupted WHOIS packet and
1769 caused problem with router to router connections. Affected
1770 file silcd/command.c.
1772 Fixed also silc_server_command_whois_check the same way
1773 as for the IDENTIFY command.
1775 * Added new SilcIDListStatus to the server in the SilcIDListData
1776 structure. The status now includes the current status of
1777 the entry (like registered, resolved etc.). Affected file
1778 silcd/idlist.[ch]. Defined a bunch of different status types
1779 as well. This replaced the old boolean registered field as well.
1781 Added resolve_cmd_ident field to the SilcClientEntry structure
1782 too so that if the entry is for example being resolved so
1783 another command may attach to the same pending command reply
1784 without requiring to resolve the same entry again. This concept
1785 should optimize the WHOIS and the IDENTIFY resolving under
1786 heavy load by taking away unnecessary resolving for entries
1787 that are being resolved already.
1789 Added support for adding multiple pending commands for one
1790 command idenfier. Affected file silcd/command[_reply].[ch].
1792 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1793 before deleting the data. Otherwise the hash table will have
1794 freed data in comparison functions. Affected file is
1795 silcd/command_reply.c.
1797 * Fixed silc_idlist_replace_client_id to add the new entry to
1798 the cache with NULL nickname. Otherwise there will be invalid
1799 memory as the nickname after the nickname is freed. Affected
1800 file silcd/packet_receive.c.
1802 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1803 saved into wrong slots because the previous number of entries
1804 was not taken into account. Affected file silcd/idlist.c.
1805 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1807 * If we are router and we receive JOIN notify to a channel that
1808 does not have any users then notified client is marked as the
1809 channel founder, as it is it. The affected file is
1810 silcd/packet_receive.c
1812 * Added to the extended hash table API's table_del_*ext functions
1813 the destructor as argument too, so that the caller can decide
1814 which destructor to use or whether to use destructor at all.
1815 Affected file lib/silcutil/silchashtable.[ch].
1817 * Fixed ID Cache purging. It actually deleted the entries from
1818 the hash table after the data was freed. The hash table ended
1819 up comparing freed memory. The affected file is
1820 lib/silccore/silcidcache.c.
1822 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1824 * Fixed Irssi SILC client's KILL command's HELP syntax.
1826 * The USERS command now resolves the detailed user information
1827 if the userinfo field is missing. Affected file is
1828 lib/silcclient/command_reply.c.
1830 * Do not print error in silc_file_read if the read file does
1831 not exist. Just silently return NULL. Affected file is
1832 lib/silcutil/silcutil.c.
1834 * Fixed the silc_log_output to not wine about NULL filename
1835 and to not create some bogus " " filename. Affected file is
1836 lib/silcutil/silclog.c.
1838 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1840 * Fixed various printing bugs on the user interface in the
1841 Irssi SILC Client. Minor changes that were forgotten from
1844 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1846 * Fixed the configure.in.pre and the compilation and distribution
1847 environment to support the new autoconf 2.52. That version is
1848 now required to compile the CVS trunk.
1850 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1852 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1853 to generally parse user@fqdn format strings. Affected file
1854 lib/silcutil/silcutil.c.
1856 * Added nickname_format and nickname_force_format fields to the
1857 SilcClientParams structure. The first one defines the format
1858 for the nicknames that the library will enforce if the receives
1859 multiple same nicknames. The second one is boolean value and
1860 can be used to force the library to always enforce the format
1861 to the nicknames regardles whether there are multiple nicknames
1862 or not. This configurable formatting was employed to flexibly
1863 support accessing multiple nicknames from the user interface.
1864 The userinterface can now set the nicknames to what ever format
1865 they prefer. Affected file lib/silcclient/silcapi.h.
1867 Added function silc_client_nickname_format to the file
1868 lib/silcclient/idlist.c. It performs the nickname formatting.
1870 Added new field `hostname´ to the SilcClientEntry context.
1871 It holds the hostname of the client. Affected file is
1872 lib/silcclient/idlist.h.
1874 * Irssi SILC Client sets the nicknames in nick@hostn format.
1875 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1876 irssi/src/silc/core/silc-core.c.
1878 The WHOIS printing now also shows both the real nickname and
1879 the formatted nickname so that user knows how to access the
1880 user if there are multiple same nicknames cached. Affected
1881 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1882 printing formatting too to take the hostname now as a separate
1883 argument. The Affected file is
1884 irssi/src/fe-common/silc/modules-formats.[ch].
1886 * Changed the silc_client_get_clients_local to accept the formatted
1887 nickname as argument. It accepts the real nickname too but the
1888 formatted nickname can be used to find the true entry from
1889 multiple entries. Affected file lib/silcclient/silcapi.h and
1890 lib/silcclient/idlist.c.
1892 * Added nickname_format_parse field to the SilcClientParams.
1893 It is a callback function provided by the application to parse
1894 the nickname out of the formatted nickname string. The library
1895 calls it to get the nickname from the formatted string. Since
1896 the application generally knows better the format of the nickname
1897 string it parses it instead of the library, even though library
1898 encodes the formatted string. If the callback function is not
1899 provided then the library will use the string as is. The
1900 affected file is lib/silcclient/silcapi.h.
1902 * All the nickname strings passed to the client library in
1903 commands are now expected to be formatted nickname strings.
1904 If the command does not support the formatted nickname string
1905 it will assume that the sent string is the actual nickname.
1906 Affected file lib/silcclient/command.c.
1908 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1910 * Added public key authentication support to OPER and SILCOPER
1911 commands in the client library. Affected file is
1912 lib/silcclient/command.c.
1914 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1916 * Changed the get_auth_methdod client operation to be asynchronous.
1917 It can be async if the application resolves the authentication
1918 method from the server during the negotiation. Added new
1919 SilcGetAuthMeth completion callback that the application will
1920 call after resolving the authentication method.
1922 Added function silc_client_request_authentication_method that
1923 the application can use to resolve the authentication method
1924 from the server. Added also SilcConnectionAuthRequest callback
1925 that the library will call after the server has replied. The
1926 application can call this function if it does not know the
1927 current authentication method.
1929 Affected files are lib/silcclient/client.c and
1930 lib/silcclient/silcapi.h.
1932 * The Irssi SILC client now automatically resolves the authentication
1933 method incase any configuration information is not present (and
1934 currently there never is). The affected file is
1935 irssi/src/silc/core/client_ops.c.
1937 * Fixed public key authentication from the client library.
1938 Affected file lib/silcclient/protocol.c. Changed also the
1939 protocol specification about the public key authentication in
1940 the connection authentication protocol. The actual data to be
1941 signed is now computed with a hash function before signing.
1943 * Fixed the public key authentication from the server as well.
1944 Affected file silcd/protocol.c.
1946 * Removed the mlock()'s from the memory allocation routines.
1947 Affected file lib/silcutil/silcmemory.c. The ./configure does
1948 not check anymore for the mlock(). Affected file is
1951 * Fixed USERS command in server to allow the execution of the
1952 command for private and secret channels if the client sending
1953 the command is on the channel. Affected file silcd/command.c.
1955 * Fixed silc_client_get_clients_local to return the clients
1956 count correctly. It could return wrong value. Affected file
1957 lib/silcclient/idlist.c.
1959 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1961 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1962 types. The assembler optimizations seemed not to like 64-bit
1963 data types. The assmebler optimizations thus are now enabled
1964 also for BSD systems as opposed to only enable them for Linux.
1966 * Do not check for threads at all on BSD systems. Affected
1967 file configure.in.pre.
1969 * Removed -n and -h options from the Irssi SILC Client since
1970 they are not used in silc.
1972 * Fixed the prime generation to assure that the first digit
1973 of the generated random number is not zero since our conversion
1974 routines does not like number strings that starts with zero
1975 digit. If zero digit is seen the random number is regenerated.
1976 This caused some corrupted RSA keys when the zero first digit
1977 was met. Affected file lib/silcmath/silcprimegen.c.
1979 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1981 * Fixed WIN32 configuration in the ./configure script.
1982 Fixed to include xti.h on environments that has it.
1983 Patches by Carsten Ilchmann and andrew.
1985 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1987 * Changed the silc_id_create_client_id to be collision
1988 resistant. It is now assured that there cannot be created
1989 two same client ID's. I suspect that some weird bugs in
1990 the server were actually caused by duplicate Client IDs.
1991 Affected file silcd/serverid.[ch]. A router receiving
1992 new ID now also assures and informs the sending server
1993 if the ID caused collision.
1995 * Changed the silc_id_create_channel_id to also assure that
1996 there are no collisions.
1998 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2000 * Statement about ignoring the Mutual Authentication flag when
2001 performing rekey with PFS was a bit misleading. It is ignored
2002 if it was set in the initial negotiation, it cannot be even
2003 set in the rekey. Fixed in the ke-auth draft. Started the
2004 new versions of the protocol drafts in the doc/.
2006 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2008 * Fixed a bug in silc_client_command_identify_save when saving
2009 new channel information. The channel name was no duplicated
2010 and caused crash on exit. Affected file is
2011 lib/silcclient/command_reply.c.
2013 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2015 * Fixed the getkey command handling in the server. Send just
2016 empty OK reply to the sender if the key could not be fetched
2017 (but everything else was ok, like the key just was not available).
2018 Changed the public key parameter to optional in the protocol
2019 specs so that empty OK reply can be sent. Affected file
2022 Added a message to Irssi SILC client to tell to user if the
2023 server did not return a public key.
2025 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2027 * Fixed a channel key regeneration bug. It registered new
2028 timeout tasks exponentially until all system resources were
2029 used. Affected file silcd/server.c.
2031 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2033 * Added the SILC Document generator to the scripts/silcdoc.
2034 It can be used to generate the Toolkit Reference Manual out
2035 of the source tree. Internally it will also use the RoboDoc
2036 generator now imported in util/robodoc.
2038 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Added couple of return's in rekey protocol if error orccurred
2041 during the protocol. The execution must be terminated.
2042 Affected file silcd/protocol.c. Also, terminate the protocol
2043 always with timeout.
2045 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2047 * The client's Client ID was created initally from the wrong
2048 nickname (it could have been in format nick@host) in the
2049 silc_server_new_client. Affected file silcd/packet_receive.c
2051 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2053 * Added some SILC_LOG_ERROR's to various error conditions
2054 if client could not be added to ID cache. Affected files
2055 silcd/packet_receive.c and silcd/server.c.
2057 * When client's sock->user_data is freed, NULL also the
2058 client->router and client->connection pointers. Added check
2059 for these pointers being NULL to various places around the
2060 code. Affected file silcd/server.c.
2062 * Added client->data.registered == TRUE checks to various
2063 places around the code to assure that unregistered client's
2064 are not handled when it is not allowed. Affected file
2067 * Added `bool registered' fields to all
2068 silc_idlist_[server|client]_get_* routines to indicate whether
2069 the fetched client needs to be registered or not. Affected
2070 file silcd/idlist.[ch].
2072 * Add your own entry as registered to the ID cache in the
2073 server. Affected file server.c.
2075 * Fixed a bug in silc_server_new_server. The SilcServer was
2076 set as the new server's context instead of SilcServerEntry.
2077 This naturally caused some weird bugs.
2079 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2081 * Do not delete the channel rekey task when adding it
2082 for in silc_server_create_channel_key.
2084 * Changed the silc_server_create_channel_key to return
2085 TRUE or FALSE to indicate the success of the channel key
2088 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2090 * Fixed MSVC++ project files and added missing files to
2091 Makefiles under win32/.
2093 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2095 * Do not add TCP_NODELAY flag if the operating system
2096 does not have it defined. Affected files are
2097 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2099 * Fixed buffer overflow from Irssi SILC Client. Affected
2100 file irssi/src/fe-common/core/themes.c.
2102 * Fixed double free in client library in the file
2103 lib/silcclient/client.c when disconnecting from server.
2105 * Applied double free patch from cras to Irssi SILC client.
2106 Affected files irssi/src/core/[modules/expandos].c
2108 * Fixed the disconnection handling to Irssi SILC Client.
2109 The application must call silc_client_close_connection
2110 in ops->connect client operation in case of failure of
2111 the connection. Affected file is
2112 irssi/src/silc/core/client_ops.c.
2114 * Do not set sock->protocol to NULL in the function
2115 silc_client_close_connection after executing the protocol's
2116 final callback since the sock might not be valid anymore.
2117 Affected file lib/silcclient/client.c.
2119 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2121 * Do not enable SILC_THREADS if the linking with libpthread
2122 did not happen. Affected file configure.in.pre.
2124 * Added notion to protocol specification that server must
2125 verify the sent authentication payload with CMODE when
2126 setting the channel founder key. Implemented it to the
2127 server. Affected file silcd/command.c.
2129 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2131 * Added _EXTRA_DIST SILC distribution variable to the
2132 distributions file. It is used to conditionally add extra
2133 files or directories to the specific distribution. Affected
2134 files ./prepare, Makefile.am.pre and distributions.
2136 Removed the `_' from the start of the distribution names.
2139 * Added README.WIN32 for instructions to compile the Toolkit
2142 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2144 * Fixed a double free in disconnection in the server. Affected
2145 file is silcd/server.c.
2147 * Fixed the lib/silcske/groups.c to work now also with GMP
2148 MP library. The string conversion did not work when using
2149 specific base and the base is indicated in the string as well.
2151 * Created win32/ directory which now includes MSVC++ specific
2152 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2153 It will appear only in the toolkit distribution
2155 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2157 * Changed the key material distribution function in case when
2158 the hash output is too short. The data is now concatenated
2159 a bit differently than it used to. Made the change to the
2160 SKE protocol specification.
2162 * Added better GMP detection to configure.in.pre. A patch
2165 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2167 * Fixed a minor bug in SKE that might cause some problem on
2168 some platforms. Affected file lib/silcske/silcske.c.
2170 * Added the cookie checking for initiator in the SKE. It checks
2171 that the responder returns the sent cookie unmodified. The
2172 affected file is lib/silcske/silcske.c. Added new SKE
2173 error type INVALID_COOKIE that can be sent during the
2174 negotiation. Fixed some memory leaks as well.
2176 * Added the "invalid cookie" error message to Irssi SILC client's
2179 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2181 * Added `task_max' field to the SilcClientParams to indicate
2182 the maximum tasks the scheduler can handle. If set to zero,
2183 default values are used. Affected file lib/silcclient/silcapi.h.
2185 * Fixed memory leaks in silc_client_close_connection. Affected
2186 file lib/silcclient/client.c.
2188 * Added silc_client_del_client_entry to client library to free
2189 all memory of given client entry. Affected file is
2190 lib/silcclient/idlist.[ch].
2192 * Added new functions silc_client_del_channel and
2193 silc_client_del_server to delete channel and server entries.
2194 Affected file lib/silcclient/[silcapi.h/idlist.c].
2196 * Removed silc_client_del_client_by_id from silcapi.h.
2198 * Fixed the INFO command to return the server's own info
2199 correctly when querying by Server ID. Affected file is
2202 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2204 * Removed the non-blocking settings in WIN32 code in the
2205 silc_sock_[read/write] and added SleepEx instead. Affected
2206 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2207 of input data is now checked with FIONREAD and ioctlsocket.
2209 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2211 * Call silc_schedule_task_del_by_context in the
2212 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2213 Affected file lib/silccore/silcprotocol.c.
2215 * Call silc_protocol_cancel for active protocols in the
2216 silc_server_close_connection if the funtion
2217 silc_server_free_sock_user_data has not been called.
2218 Affected file silcd/server.c.
2220 * Generic tasks cannot be deleted using the del_by_fd
2221 task deleting function since generic tasks does not match
2222 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2224 * Added a notion to SILCOPER help file that the SILCOPER works
2225 only on router server, not on normal server.
2227 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2229 * Added for WIN32 support for the new scheduler as well.
2230 Affected file lib/silcutil/win32/silcwin32schedule.c.
2232 * Fixed the SHA1 implementation to work on various platforms.
2234 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2236 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2237 API. It is part of the scheduler now. Everything else is
2238 as previously but some functions has changed their names.
2239 Checkout the lib/silcutil/silcschedule.h for the interface.
2240 Updated all applications to use the new interface. Affected
2241 files are lib/silcutil/silcschedule.[ch].
2243 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2245 * Found a bug in the SKE implementation. The HASH value,
2246 specified by the protocol, was not computed correctly. The
2247 public key of the responder was not added to the computation
2248 even though it is mandatory. Affected file lib/silcske/silcske.c.
2249 This unfortunately causes incompatibilities with older
2250 clients and servers.
2252 * Added WIN32 specific network init and uninit functions:
2253 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2254 the Winsock2. Affected file lib/silcutil/silcnet.h and
2255 lib/silcutil/win32/silcwin32net.c.
2257 * Set the socket always to nonblocking mode on WIN32 after
2258 reading data or writing data. Affected file is
2259 lib/silcutil/win32/silcwin32sockconn.c.
2261 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2263 * Fixed various compilation problems under WIN32. Affected
2264 files lib/silcutil/win32/silcwin32thread.c and
2265 lib/silcutil/win32/silcwin32schedule.c.
2267 * Removed all _internal.h #includes from public header
2268 files. Internal headers must never be included from
2271 Removed also the lib/silcske/payload_internal.h file.
2273 * All include files that may be needed (public and some others
2274 included by the public headers) by application developers are
2275 now copied to the ./includes directory. It does not copy any
2276 internal headers. Affected file Makefile.defines.pre and all
2277 Makefile.am's under lib/ and subdirs.
2279 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2281 * Do not change the ~/.silc directory's permissions automatically.
2282 Affected file irssi/src/silc/core/clientutil.c.
2284 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2286 * Do not cancel the protocol in silc_server_close_connection
2287 it might cause recursion. Now cancelled in the function
2288 silc_server_free_sock_user_data. Affected file silcd/server.c.
2290 * Fixed the silc_server_remove_clients_by_server to regenerate
2291 the channel keys correctly finally. Added also new function
2292 silc_server_remove_clients_channels to actually do it.
2293 Affected file silcd/server.c.
2295 * Fixed the silc_server_new_channel to not crash by giving
2296 wrong router to the new channel. Affected file is
2297 silcd/packet_receive.c.
2299 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2301 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2302 which is given as argument to the silc_client_alloc now.
2303 It can be used to configure the client and set various parameters
2304 that affect the function of the client.
2306 * The USERS command in server did not check whether the channel
2307 is private or secret. Affected file silcd/command.c.
2309 * Added new argument to the USERS command in protocol specification.
2310 The USERS command now can take the channel name as argument
2311 as well. Added support for this in client and server and
2312 updated the protocol specs.
2314 * Completed the GETKEY command in client. It can be now used
2315 to fetch also servers public key not only some clients.
2316 Affected files lib/silcclient/command[_reply].c.
2318 * Added silc_client_get_server to return server entry by the
2319 server name. Affected files lib/silcclient/silcapi.h and
2322 * Redefined the IDENTIFY command in protocol specification to be
2323 more generic. It now can be used to query information about
2324 any entity in the SILC Network, including clients, servers and
2325 channels. The query may be based either the entity's name
2326 or the ID. Added support for this in both client and server.
2328 Affected files silcd/command.c and lib/silcclient/command.c
2329 and command_reply.c.
2331 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2332 the _from_client and _from_server functions. Affected file
2335 * Added silc_client_get_channel_by_id_resolve to the file
2336 lib/silcclient/silcapi.h to resolve channel information by
2337 its ID. Added also silc_client_get_channel_by_id that
2338 does not resolve it from the server.
2340 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2342 * Added SilcServerEntry context into the client library
2343 to represent one server. The INFO command now allocates
2344 these to save the resolved server info. For now on the
2345 client library will also keep information about servers,
2346 connected and resolved with INFO.
2348 The INFO command now allocates the SilcServerEntry context
2349 and saves the server info there. The COMMAND_REPLY in
2350 the INFO now returns the parameters to application in
2351 same order as defined in the protocol specification.
2353 The entries are cached in the client->server_cache.
2355 * The INFO command is now issued after received the Client ID
2356 from the server. Affected file lib/silcclient/client.c.
2358 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2359 to the application as the mode changer might be server.
2360 It is guaranteed that NULL is not returned anymore to the
2361 application. Affected file lib/silcclient/client_notify.c.
2363 The ID Type is now also passed to the application so that
2364 it can check whether the returned entry is SilcClientEntry
2367 Added new function silc_client_get_server_by_id to return
2368 the server entry by ID. Affected files are the
2369 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2371 * Do not create the channel in the Irssi SILC Client when issuing
2372 the JOIN command but when received the sucessful JOIN command
2373 reply. Otherwise the channel might get created even though we
2374 could not join it. The Affected file is
2375 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2377 * Fixed a channel joining bug in router. The router must also
2378 check the channel modes, invite and ban lists etc. when serving
2379 the JOIN command sent by normal server. Affected file is
2380 silcd/command.c. The router now resolves the client's
2381 information from the server who sent the JOIN command if it
2382 does not know it, and processes the JOIN command only after
2385 * Changed the SilcCommandCb to take new argument; void *context2.
2386 Affected file lib/silccore/silccommand.h
2388 The second argument in the command callbacks in the server now
2389 includes the SilcServerCommandReplyContext if the command was
2390 called as pending command callback from the command reply.
2391 Otherwise it is NULL. When called as pending the status of the
2392 command reply will be checked and if it was erronous the
2393 error will be sent to the original sender of the command.
2394 This way the client always receives the error messages even
2395 though the server was actually the one who received the error
2396 when it resent the command to router, for example. Affected
2397 files silcd/command[_reply].[ch].
2399 * Fixed sending WHOWAS command's error message to client if
2400 the requested client could not be found. It was missing.
2403 * Changed the CMODE and CUMODE commands reply arguments in the
2404 protocol specification. The Channel ID is now sent in both
2405 of the commands to identify the channel. Implemented this
2406 new feature to the client and server. Affected files
2407 lib/silcclient/command_reply.c and silcd/command.c.
2409 * Made better checks for invite and ban lists in the JOIN
2410 command in server. Affected file silcd/command.c.
2412 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2414 * The server now performs the incoming host IP/DNS lookup
2415 using the silc_socket_host_lookup and thus does not block
2416 the server anymore. Affected file silcd/server.c.
2418 * Completed the multi-thread support for SILC Scheduler in
2419 the lib/silcutil/silcschedule.c.
2421 * Fixed the configure.in.pre to detect the pthread correctly
2424 * Fixed a deadlock in silc_task_queue_wakeup in the file
2425 lib/silcutil/silctask.c.
2427 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2429 * Added new function silc_schedule_wakeup that is used in
2430 multi-threaded environment to wakeup the main thread's
2431 schduler. It needs to be used when a thread adds a new task
2432 or removes a task from task queues. After waking up, the
2433 scheduler will detect the task queue changes. If threads
2434 support is not compiled in this function has no effect.
2435 Implemented the wakeup mechanism to both Unix and WIN32
2436 systems. Affected files are lib/silcutil/silcschedule.[ch],
2437 lib/silcutil/unix/silcunixschedule.c and the
2438 lib/silcutil/win32/silcwin32schedule.c.
2440 * Added new function silc_task_queue_wakeup to wakeup the
2441 scheduler by the specified task queue. Affected file
2442 lib/silcutil/silctask.[ch].
2444 * The silc_socket_host_lookup_start now wakes up the scheduler
2445 after adding the timeout task. Affected file is
2446 lib/silcutil/silcsockconn.c.
2448 * The silc_socket_host_lookup is synchronous now if the threads
2449 support is not compiled in. However, the callback is still
2450 called asyncronously through the scheduler, anyway. Affected
2451 file lib/silcutil/silcsockconn.c.
2453 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * Added new function silc_socket_host_lookup to perform
2456 asynchronous IP and FQDN lookups for the socket connection.
2457 Affected files lib/silcutil/silcsockconn.[ch].
2459 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2461 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2462 that may or may not compile the mutex support in.
2464 Changed the silc_mutex_alloc interface. It allocates the
2465 mutex now to the sent pointer and returns TRUE or FALSE.
2467 Affected file lib/silcutil/silcmutex.h.
2469 * Wrote the SILC Task Queue interface to support multi-threads.
2470 Affected file lib/silcutil/silctask.[ch].
2472 * Wrote the SILC Scheduler to support multi-threads. Affected
2473 file lib/silcutil/silcschedule.c.
2475 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2477 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2478 in lib/silcutil/win32/.
2480 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2482 * Defined SILC Mutex API and SILC Thread API and implemented
2483 them for Unix. Affected files are
2484 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2485 lib/silcutil/unix/silcunixmutex.c and
2486 lib/silcutil/unix/silcunixthread.c.
2488 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2490 * Fixed the silc_server_remove_clients_by_server's channel
2491 key re-generation. The hash table handling was incorrect
2492 and would not work with many channels. Affected file is
2495 * Fixed some memory leaks around the server code.
2497 * Rewrote the silc_server_get_users_on_channel to support IPv6
2498 based Client ID's. Affected file silcd/server.c.
2500 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2501 specification. However, a separate document must be written
2502 to define the detailed signing procedure and the payload
2503 associated with the flag. Defined the flag to the
2504 lib/silccore/silcchannel.h as well.
2506 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2508 * Changed the dynamic tables to static size tables in the
2509 lib/silccrypt/silchmac.c.
2511 * Removed GCC dependencies from the code. A patch by cras.
2513 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2515 * Do not show the error "Error receiving packet bla bla"
2516 in server if it really was not an error (-2 means that reading
2517 is pending). Affected file silcd/server.c.
2519 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2521 * Fixed a possible crash in silc_server_remove_clients_by_server
2522 in silcd/server.c. Fixed there also some memory leaks.
2524 * Fixed the silc_idlist_replace_client_id. It could replace
2525 wrong key in the hash table. Affected file silcd/idlist.c.
2527 * Do not check whether there are global users on the channel
2528 if the channel->global_users is FALSE. Affected functions
2529 silc_server_remove_from_one_channel and
2530 silc_server_remove_from_channels in silcd/server.c. Also,
2531 do not check if the removed client is local as we can be
2532 sure that global client was not removed from the channel
2533 and checking for global users is not needed.
2535 * The silc_server_remove_clients_by_server now re-generates
2536 the channel keys correctly for those channels that had
2537 clients removed from them. Affected file silcd/server.c.
2539 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2541 * Found the reason of random crashes in the server. We weren't
2542 ignoring the SIGPIPE signal (which can be sent in write())
2543 and it crashed the server. Affected file silcd/silcd.c.
2545 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2547 * Assure that sock->user_data is not NULL in the function
2548 silc_server_packet_send in silcd/packet_send.c.
2550 * Disconnect the remote connection if it could not be added
2551 to any ID lists in the server. The affected file is
2554 * Check in silc_server_packet_send[_real/dest] that the
2555 socket is not disconnecting and ignore the data if it is.
2556 Affected file silcd/packet_send.c.
2558 * Define inline to __inline on native WIN32 compilation.
2559 Affected file includes/silcwin32.h.
2561 * Added some explicit type casts for inline code since MSVC
2562 require them. Affected files lib/silcutil/silcbuffer.h,
2563 lib/trq/silcdlist.h and lib/trq/silclist.h.
2565 * Print warning in log files from now on if the packet
2566 decryption fails. Affected file silcd/server.c.
2568 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2570 * Changed the `say' client operation's interface to accept
2571 new `type' argument to indicate the type of the message sent
2572 by the library. The application may filter the library's
2573 messages according the type. The affected file is the
2574 lib/silcclient/silcapi.h.
2576 * Added two new functions to lib/silcclient/silcapi.h:
2577 silc_client_del_client and silc_client_del_client_by_id.
2578 Affected file lib/silcclient/idlist.c.
2580 * Moved the clientincludes.h from includes/ to silc/ and
2581 serverincludes.h from includes/ to silcd/.
2583 * The modes for the CMODE and CUMODE are now passed as
2584 uint32 for application with COMMAND_REPLY. The affected
2585 file is lib/silcclient/command_reply.c.
2587 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2589 * /WHOIS without arguments shows client's own information.
2590 Affected file lib/silcclient/command.c.
2592 * Changed PING to not accept any arguments. The specs
2593 says that client can ping only the connected server so
2594 requiring an argument is not needed. Affected file is
2595 lib/silcclient/command.c.
2597 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2599 * Fixed a fatal bug in private message sending and reception
2600 encryption and decryption when using private message keys.
2601 The implementation was incorrect and did not follow the
2602 specification. It causd that some of the message were
2603 lost since it did not use the sending and receiving keys
2604 as the protocol suggests. This has been fixed and will cause
2605 incompatibilities with older clients when sending private
2606 message encrypted with private message keys. Affected files
2607 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2608 and various other in Irssi SILC Client.
2610 Added `responder' boolean argument to the functions
2611 silc_client_add_private_message_key[_ske] to indicate when
2612 the key is added as responder or initiator of the key
2615 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2617 * Removed the silc_ske_check_version function and created
2618 a SilcSKECheckVersion callback. Added also a function
2619 silc_ske_set_callbacks that is now used to set all SKE
2620 callbacks. The callback functions are not given to
2621 the SKE functions anymore, but this function is used to
2624 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2626 * Added `silc_version' argument to the silc_client_alloc
2627 to define the version of the application for the library.
2628 The library will use the version string to compare it
2629 against the remote host's (usually a server) version
2630 string. Affected file lib/silcclient/silcapi.h
2632 * Added the KE protocol context to Key Agreement context
2633 in client library so that we can abort the SKE if it
2634 is in process when we get timeout. Affected file is
2635 lib/silcclient/client_keyagr.c.
2637 * Do not resolve the client ID forever if it returns in the
2638 first time that such client does not exist. This was done
2639 for example with private message. Affected file is
2640 lib/silcclient/client_prvmsg.c.
2642 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2644 * Do not add regex.h for WIN32. The affected file
2645 includes/silcincludes.h.
2647 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2648 not work yet 100%. It generates the DLL's automatically
2649 when compiling with --with-win32 under cygwin.
2651 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2653 * lib/contrib/regex.c is not compiled on WIN32.
2655 * Added silc_net_get_socket_opt function to the
2656 lib/silcutil/silcnet.h.
2658 * Added includes/silcwin32.h for WIN32 specific includes
2661 * Do not use ptime structure or any of the posix process
2662 functions on WIN32 in lib/silccrypt/silrng.c.
2664 * Added silc_gettimeofday to provide generic function
2665 for struct timeval on all platforms. Added the function
2666 to lib/silcutil/silcutil.h.
2668 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2670 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2671 library as they clearly belong there. As a plus side we
2672 can make the actual socket connection routines platform
2675 Added also new generic function silc_socket_read and
2676 silc_socket_write (that used to be silc_packet_[read/write].
2677 The implementation of these are platform specific.
2679 * Added WIN32 specific routines of silc_socket_[read/write]
2680 to lib/silcutil/win32/silcwin32sockconn.c.
2682 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2684 * Added preliminary support for native WIN32 compilation under
2685 cygwin (using the -mno-cygwin option for GCC) to the
2686 ./configure.in.pre. The --with-win32 now prepares the
2687 compilation for native WIN32.
2689 * Rewrote the SILC Scheduler interface in the file
2690 lib/silcutil/silcschedule.h. The scheduler is now context
2691 based and does not have anymore any global static scheduler.
2692 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2693 and created lib/silcutil/win32 directory for WIN32 based
2696 * Added Unix specific network routines to the
2697 lib/silcutil/unix/silcunixnet.c and the old
2698 lib/silcutil/silcnet.c includes now only generic routines.
2700 Added WIN32 specific network routines to the
2701 lib/silcutil/win32/silcwin32net.c.
2703 * Added Unix specific utility functions from the
2704 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2706 * Added WIN32 SILC Scheduler to the file
2707 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2710 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2712 * Do not handle JOIN notify in the server if the target client
2713 is not registered (idata->registered == FALSE). The affected
2714 file is silcd/packet_receive.c.
2716 * Update the nickrec->founder in event_cumode in the Irssi SILC
2717 client. Affected file irssi/src/silc/core/silc-channels.c.
2719 * Fixed the CUMODE_CHANGE notify handling in the server when
2720 server and router are announcing their clients on channels.
2721 Now the mode changes are saved and notified correctly. The
2722 affected file is /silcd/packet_receive.c.
2724 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2725 They really did not replace the cache entry in the ID Cache.
2726 Now they do that. Affected file silcd/idlist.c.
2728 * Fixed the KICK notify handling in the Irssi SILC client to
2729 update the channel records so that the kicked client does not
2730 appear to be on the channel. The affected file is
2731 irssi/src/silc/core/silc-channels.c.
2733 * Always update the conn->current_channel when executing command
2734 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2736 * Fixed the KILL notify handling in Irssi SILC client to remove
2737 the killed client on all channels.
2739 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2741 * Fixed the silc_parse_command_line to remove extra spaces
2742 from the start and end of the arguments. Affected file is
2743 lib/silcutil/silcutil.c.
2745 * Cancel and free any active protocol in the function
2746 silc_server_close_connection. Affected file silcd/server.c.
2748 * Cancel and free any active protocol in the function
2749 silc_client_close_connction. Affected file is
2750 lib/silcclient/client.c.
2752 * Do not execute the KILL command for clients that are in
2753 history (ie. they are not in the network). Affected file is
2756 * Fixed KILL notify handling, client does not crash anymore.
2757 Affected file irssi/src/silc/core/silc-channels.c.
2759 * Reduced the default packet buffer size from 2048 to 1024 in
2760 lib/silccore/silcpacket.c.
2762 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2763 counter to the SKE context that is incresed when the SKE library
2764 performs async operation outside the library. If the outside
2765 process frees the SKE context and FREED status will be set
2766 and the library will detect after the sync operation that the
2767 libary is freed. The affected files are
2768 lib/silcske/silcske[_status].[ch].
2770 * Resolve the client entry information in the function
2771 silc_client_channel_message to assure that NULL pointer is not
2772 passed as client entry to the application. */
2774 * Fixed the task timeout calculation to assure that there is
2775 never negative timeouts. The affected file is
2776 lib/silcutil/silcschedule.c.
2778 * Fixed the channel user mode notification sending in server.
2779 It was sent point-to-point to the router (or to server by router)
2780 but it needs to be destined to a channel. The routines now
2781 supports sending the channel user mode notifys to the channels
2782 when announcing clients and channels. Affected files are
2783 silcd/server.c and silcd/packet_receive.c.
2785 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2786 It did not actually replace the old channel entry in the cache.
2787 Affected file lib/silcclient/client_notify.c.
2789 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2791 * Fixed a possible crash in silc_packet_send_prepare. It now
2792 assures always that there is enough space in the buffer and
2793 at the tail area of the buffer (for MAC).
2795 Fixed the inbound buffer reallocation in silc_packet_read.
2796 It was old code and did not handle the reallocation correctly.
2799 The affected file is lib/silccore/silcpacket.c.
2801 * Fixed buffer overflow in silc_parse_nickname in the file
2802 lib/silcutil/silcutil.c.
2804 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2806 * make install generates new server keys only if there is not
2809 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2811 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2812 Added check that if the NOREPLY is set then we will not send
2813 the away message. This avoids infinite loop of away messages
2814 if both clients are away. The affected file is
2815 lib/silcclient/client_prvmsg.c.
2817 * Fixed client crash if /NICK was given without arguments.
2818 Affected file lib/silcclient/command.c.
2820 * Server does not send the invite list in INVITE command back
2821 to the client if the list was not altered. Added this notion
2822 to the protocol spec as well. Affected file silcd/command.c.
2824 Fixed possible crash in INVITE command by checking the
2825 value of silc_server_get_client_route command.
2827 * Fixed the INVITE notify type handling. The arguments are now
2828 taken in correct order and client does not crash. The affected
2829 file is irssi/src/silc/core/silc-channels.c.
2831 Removed the "Inviting xxx to channel" message from the
2832 client library away and let the application handle it.
2833 Affected file lib/silcclient/command.c. Added that message
2834 to Irssi SILC client's message formats.
2836 * Fixed CMODE command crash in client. It now checks the
2837 amount of arguments correctly and does not crash. The affected
2838 file is lib/silcclient/command.c.
2840 * Do not create new channel automatically in silc_channels_join
2841 but check whether the channel by that name already exists.
2842 Affected file irssi/silc/core/silc-channels.c.
2844 * Do not send the SERVER_SIGNOFF to router if the disconnected
2845 entity was the router. Affected file silcd/server.c.
2847 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2848 SILC client as it was missing from there.
2850 Added the handling of the KICK notify to the Irssi SILC client
2851 as it was missing. Added "you have been kicked" message to
2852 Irssi SILC client's message modules formats.
2854 Added the handing of the KILL notify to the Irssi SILC client
2855 as it was missing. Added the kill message module formats
2858 The affected file is irssi/src/silc/core/silc-channels.c.
2860 * The router did not save the channel mode the server announced.
2861 Affected file silcd/packet_receive.c.
2863 * Fixed a possible crash in INFO command in server. If the
2864 server did not provide the server info it crashed. Affected
2865 file silcd/command.c.
2867 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2869 * Fixed the GETKEY command in the server to check also the
2870 global list. Otherwise the GETKEY would not work correctly
2871 in normal SILC server. Affected file silcd/command.c.
2873 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2875 * Fixed GETKEY crash, it crashed if the command did not succseed.
2877 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2879 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2880 is now real and not just an macro interface to GMP.
2882 Removed the entire GMP from the source tree and imported new
2883 NSS MPI library instead. Reason for removing GMP is that it is
2884 extremely large and compiles extremely slow. The NSS MPI
2885 is only a few files and compiles in less than 10 seconds.
2886 The speed is also about the same as GMP. The MPI is imported
2887 to lib/silcmath/mpi.
2889 If the system has GMP installed we will still use the GMP.
2890 If it is not then the NSS MPI will be compiled.
2892 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2894 * Merged a long nickname (127 characters long) crash bugfix from
2895 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2897 * Merged a freed memory reference bugfix from Irssi CVS tree.
2898 Affected file irssi/src/core/commands.c.
2900 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2902 * Added the server's public key sving and verification to the
2903 server when performing the SKE. This was missing and the
2904 remote server's (or router's) public key was accepted without
2905 checking whether we have it previously or trust it at all.
2906 Affected file silcd/protocol.c.
2908 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2910 * Check in the silc_server_timeout_remote if protocol is active
2911 and make sure that the protocol's final callback is called so
2912 that all memory if freed. Affected file silcd/server.c.
2914 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2916 * silc_server_whois_send_reply crashed the server if the nickname
2917 was 127 characters long. Affected file silcd/command.c.
2919 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2921 * Added sanity check to the silc_server_new_client. If the hostname
2922 is provided inside username then check that the provided hostname
2923 really is the same as the resolved one. If the hostname was not
2924 resolved then check it from the public key. Affected file is
2925 silcd/packet_receive.c.
2927 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2928 if the server disconnected us and the connection is not valid
2929 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2931 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2932 the library to the lib/silcutil/silcutil.[ch].
2934 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2936 * Close log file after open. Affected file
2937 lib/silcutil/silclog.c.
2939 * Check whether sock == NULL in silc_client_send_packet and return
2940 if it is. Affected file lib/silcclient/silcclient.c.
2942 * Check rec->entry == NULL in the Irssi SILC Client before
2943 sending the channel message. Affecte file is
2944 irssi/src/silc/core/silc-servers.c.
2946 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2948 * Merged a splitted window bugfix from Irssi CVS tree. The
2949 affected file is irssi/src/fe-text/textbuffer-view.c.
2951 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2952 It did not print nickname.
2954 * Improved the distributions system a bit.
2956 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2958 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2959 irssi/src/fe-text/gui-window.c.
2961 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2962 to in-active server. The affected file is
2963 irssi/src/silc/core/client_ops.c.
2965 * Resolve the client in USERS command reply if the entry does
2966 not have username resolved. The affected file is
2967 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2968 command to WHOIS command to really resolve stuff. The USERS
2969 is not used any more in any critical section so WHOIS can
2970 be used even though it might be slower than IDENTIFY.
2972 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2975 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2977 * Changed the protocol API a bit more consistent in the
2978 lib/silccore/silcprotocol.[ch].
2980 * Changed the following headers to ROBODoc format:
2982 lib/silccore/silcpayload.h
2983 lib/silccore/silcprotocol.h
2984 lib/silccore/silcsockconn.h
2986 All core library headers are now formatted.
2988 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2990 * Fixed a bug in Irssi SILC client; do not show that you are
2991 server/router operator if you really are not. Affected file is
2992 irssi/src/silc/core/client_ops.c.
2994 * Renamed silc_command_free_payload to silc_command_payload_free.
2995 Affected file lib/silccore/silccommand.h
2997 * Added silcmath.h to include the prototoypes of various routines
2998 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3001 * Changed the following headers to ROBODoc format:
3003 lib/silccore/silcchannel.h
3004 lib/silccore/silccommand.h
3005 lib/silccore/silcid.h
3006 lib/silccore/silcidcache.h
3007 lib/silccore/silcmode.h
3008 lib/silccore/silcnotify.h
3009 lib/silccore/silcpacket.h
3010 lib/silcmath/silcmath.h
3012 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3014 * Added checking to the server code not to start the server if
3015 ciphers and stuff are not configured properly. Affected files
3016 silcd/serverconfig.[h] and silcd/server.c.
3018 * Changed the layout of the header files of the public interfaces
3019 in the SILC libraries. The new layout supports ROBODoc
3020 documentation tool (and some others) so that it is easy to create
3021 a library reference manual. All the other headers and source
3022 code must still follow the CodingStyle document. Also source
3023 code must not include these ROBODoc stuffs, only the headers.
3024 Furthermore, all public interface headers must now be named
3025 by using `silc' prefix, example: silcapi.h, silccipher.h.
3026 Some files were renamed due to this. All the other headers
3027 must not be used as public interfaces. I will update the
3028 CodingStyle document later. Changed following headers, so far:
3030 lib/silcclient/silcapi.h
3031 lib/silccore/silcauth.h
3032 lib/silccore/silcprivate.h
3033 lib/silccrypt/silcdh.h
3035 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3039 * Removed silc_client_packet_send_flush from the client library
3040 as it is not needed. Affected file lib/silcclient/client.[ch].
3042 * Added printing of message of unresolved authentication method
3043 to the Irssi SILC client. Added it to the module formats.
3044 Removed the same message from the client library.
3046 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3048 * Added new distribution feature, DISTLABEL. Every distribution
3049 can define own preprocessor label that can be used in the
3050 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3051 file distributions, acconfig.h.pre and prepare.
3053 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3055 * Added Makefile.defines_int to include the actual definitions
3056 for Makefile.defines.in. Tested the new distribution system,
3057 created distributions and tested installation.
3059 * Added AWAY message printing to the Irssi SILC client. Added
3060 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3062 * Added SCONNECT command to call the SILC's CONNECT command.
3063 Cannot use CONNECT directly since Irssi uses that internally.
3064 Affected file irssi/src/silc/core/silc-servers.c.
3066 Added ACTION local command. It is same as ME command but takes
3067 the channel as mandatory argument.
3069 Rewrote some of the Irssi's help files to suite for SILC
3072 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3074 * Added Makefile.defines[.in] that should for now on be included
3075 in all Makefile.am file in the source tree. That file includes
3076 all common compilation definitions for SILC source tree.
3078 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3080 * Minor changes to the ./prepare script to change the package
3081 name according the distribution name to the configure.in.
3083 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3085 * Created new distribution system. Added file `distributions'
3086 that defines all the distributions that can be created out of
3087 the SILC source tree. The ./prepare script now reads that
3088 file to determine how to prepare the distributions. The
3089 first argument to the ./prepare is the name of the distribution
3090 and second is the version of the distribution. If given
3091 without arguments it creates the default (toolkit) distribution
3092 with the default version (defined in ./prepare).
3094 All Makefile.am files that are subject to the distributions
3095 are now named as Makefile.am.pre. These are ./Makefile.am
3096 and lib/Makefile.am. Others may be changed later.
3098 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3100 * Added invite list, ban list, some key management and connection
3101 error message printing to module formats in the Irssi SILC client.
3103 * Added new silc_client_set_away_message to set the away message
3104 that is back to the person who sent private message. The
3105 affected file lib/silcclient/silcapi.h and the
3106 lib/silcclient/client_prvmsg.c.
3108 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3110 * Fixed the private message sending in the Irssi SILC client,
3111 added local command KEY to the Irssi SILC client.
3113 Added key management and key agreement message formats to the
3114 irssi/src/fe-common/silc/module-formats.[ch].
3116 Added USERS (alias WHO) printing, server/router operator
3117 indication and LIST command printing to the module formats.
3119 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3121 * Fixed channel joining notify handling, cumode notify handling
3122 from Irssi SILC client.
3124 * Added SILC specific module-formats to the Irssi SILC client so
3125 that SILC specific message hilighting, colors etc is possible.
3126 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3128 Added channel mode, channel user mode, actions, notices,
3129 whois and whowas printing to the the module-formats.c.
3131 * Fixed a bug in channel deletion in the server. The channel
3132 is not left to the cache even if the channel founder auth mode
3133 is set when there are no users anymore on the channel. Affected
3134 file silcd/server.c.
3136 * The silc_net_localhost now resolves the entire hostname including
3137 the domain name. Affected file lib/silcutil/silcnet.c.
3139 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3141 * Changed the ask_passphrase client operation to be ascynchronous.
3142 It has now a completion callback and a context that the
3143 application must call after it has got the passphrase from
3144 the user. Affected files lib/silcclient/silcapi.h,
3145 lib/silcclient/protocol.c, lib/silcclient/command.c and
3148 Added SilcAskPassphrase callback that the application calls
3149 to deliver the passphrase to the library.
3151 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3152 The public key verification and especially a certificate
3153 verification is asynchronous procedure.
3155 Added new SILC_SKE_STATUS_PENDING status to indicate the
3156 request is pending and a callback will be called to finalize
3159 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3160 indicate that remote end did not send its public key (or
3161 certificate), even though we require it. Added check for this
3162 condition in the SKE. This was a security bug, now fixed.
3164 Defined new SilcSKEVerifyCbCompletion callback that is called
3165 when the verification process is completed.
3167 The affected files lib/silcske/silcske_status.h and
3168 lib/silcske/silcske.[ch].
3170 * Changed the verify_public_key client operation to be async
3171 as well. Defined SilcVerifyPublicKey callback that is used to
3172 indicate the success of the public key verification process.
3174 Changed the server and client to use the new async client
3177 * Changed the Irssi SILC client's internal scheduler to be called
3178 twice as many times as it used to be. As a result the client
3179 should be a bit faster now. Affected file is
3180 irssi/src/silc/core/silc-core.c.
3182 * Added support to Irssi SILC client of asynchronous public key
3183 verification and passphrase inquiry. Affected file is
3184 irssi/src/silc/core/silc-core.c.
3186 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3188 * Do not say "You have left channel %s" in client library.
3189 Moved it to the application. Affected files are
3190 lib/silcclient/command.c and silc/client_ops.c.
3192 * Fixed silc_client_get_clients. Command context was not
3193 duplicated and was freed memory in the callback. Affected
3194 file lib/silcclient/idlist.c.
3196 * Do not say "you are now talking..." on JOIN command in the
3197 client library. The appliation must handle it.
3199 * Do not say ".. changed topic to" in command reply in the
3200 client libary. The application must handle it.
3202 * Fixed TOPIC command sending in the client library.
3204 * Fixed a memory leak in silc_client_command_free in the file
3205 lib/silcclient/command.c.
3207 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3209 * Imported a modified version of Irssi client to the source tree.
3210 The Irssi will be used to create a new client called
3211 Irssi SILC. Imported to irssi/.
3213 Added silc_core_init_finish function to the Irssi. Affected
3214 file irssi/configure.in.
3216 A lot changes in the Makefile.ams around the irssi tree.
3218 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3220 * Do not rehash if the new size is same as the old size of the
3221 hash table, in the silc_hash_table_rehash*. The affected file
3222 lib/silcutil/silchashtable.c.
3224 * Replaced hash_table_del_by_context calls from the server
3225 (when channel->user_list and client->channels) to the
3226 hash_table_del as it is sufficient and faster.
3228 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3230 * Added silc_hash_table_list, silc_hash_table_get and the
3231 SilcHashTableList structure to provide an alternative way to
3232 traverse the hash table. The affected files are
3233 lib/silcutil/silchashtable.[ch].
3235 * Changed the server's idlist routines to use the hash table
3236 routines to optimize the code.
3238 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3240 * Replaced the client entry's `channel' list and channel entry's
3241 `user_list' list to hash tables for optimized lookup. Changed
3242 the code to use the hash table interface around the code.
3243 Affected file lib/silcd/idlist.[ch].
3245 * Added `auto_rehash' boolean argument to the function
3246 silc_hash_table_alloc to indicate whether the hash table should
3247 auto-rehash when it thinks is appropriate time. It will
3248 increase the hash table size if the there is twice as much
3249 entries in the table than the size of the table, and will
3250 decrease the size if there are twice as less entries than
3251 the size of the table.
3253 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3255 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3257 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3259 * silc_idcache_purge_by_context deletes the entry now by context
3260 as it is supposed to do. Affected file lib/silccore/idcache.c.
3262 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3263 client is not anymore valid (WHOWAS givens the info) and not
3264 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3266 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3268 * Removed the `data' and `data_len' arguments from the ID Cache
3269 interfaces and added `name' argument. ID Cache does not handle
3270 anymore the binary data only a names associated with given ID.
3272 * When hashing a Client ID with silc_hash_id the entire ID is
3273 not hashed anymore, instead only the hash of the Client ID is
3274 hashed. This way we can access the Client ID from the cache
3275 with Client ID but with the hash of the ID (which is a hash of
3276 the nickname) as well without any difference in performance.
3278 Added also silc_idcache_find_by_id_one_ext to do one on one
3279 searching when we have the actual ID. Added also function
3280 silc_hash_client_id_compare. The affected files are
3281 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3283 * When hashing the name associated with a ID it is always done
3284 in lowercase. This way we can access the cache without worrying
3285 about case-sensitivity, even though, for example nicknames are
3288 * Fixed a bug in server with channel message sending. It put
3289 wrong ID type as destination ID. The affected file
3290 silcd/packet_send.c.
3292 * silc_idcache_del_by_context now deletes from all hash tables
3293 by context. Affected file lib/silccore/idcache.c.
3295 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3297 * Changed the client library to use the new ID Cache interface.
3298 Changes around the source tree.
3300 * Added silc_hash_table_rehash_ext to rehash with specific
3301 hash function. Affected file lib/silcutil/silchashtable.[ch].
3303 * Added silc_hash_string_compare to compare two strings in the
3304 hash table. Affected file lib/silcutil/silcutil.[ch].
3306 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3308 * Added new function silc_idcache_del_by_context into the
3309 lib/silccore/idcache.[ch].
3311 * Changed the server's ID list routines to use the new ID Cache
3312 interface. Changes around the source tree.
3314 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3316 * Added silc_hash_table_del[_by_context]_ext functions in to the
3317 lib/silcutil/silchashtable.[ch].
3319 Removed silc_hash_table_find_all* routines and added new
3320 silc_hash_table_find_foreach to replace them.
3322 Added silc_hash_table_replace_ext function as extended
3323 replacing function. Separated the simple hash table interface
3324 from the extended hash table interface in the file
3325 lib/silcutil/silchashtable.h.
3327 * Fixed minor bugs and changed it to use some of the new
3328 hash table functions in lib/silccore/idcache.c
3330 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3332 * Added new function silc_hash_table_find_all to return all keys
3333 in the hash table by the specified key. As the hash table is
3334 collision resistant it also makes it possible to have several
3335 duplicate keys in the hash table. This function may be used to
3336 find all of the keys from the hash.
3338 Added user_context arguments to the SilcHashFunction,
3339 SilcHashCompare and SilcHashDestructor to deliver user specified
3342 Added new fuctions silc_hash_table_find[_all]_ext to do
3343 extended lookup with specified hash and compare functions and
3344 specified user contexts.
3346 Added new function silc_hash_table_add_ext to add the key
3347 with specified hash function and user context.
3349 Added new function silc_hash_table_foreach to traverse all
3350 entrys in the hash table. Added SilcHashForeach callback
3353 Added new function silc_hash_table_del_by_context to delete
3354 the entry only if the context associated with the key matches.
3356 Affected files are lib/silcutil/silchashtable.[ch].
3358 * Removed silc_hash_[server/client/channel]_id and added just
3359 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3360 silc_hash_id_compare to compare two ID's using as the hash table
3361 comparison function. Added also silc_hash_data to hash
3362 binary data and silc_hash_data_compare to compare it.
3364 * Removed silc_idlist_find_client_by_hash as it is not needed
3365 anymore. Affected file silcd/idlist.[ch].
3367 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3368 to use internally the SilcHashTable. The new ID Cache is a lot
3369 faster than the old one. Some of the ID Cache interface was also
3370 rewritten and obsolete and stupid functions were removed.
3372 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3374 * Added entry_count field to the SilcHashTable to keep the number
3375 of the entries in the table. Implemented the function
3376 silc_hash_table_rehash. Added new function
3377 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3379 Fixed a minor bug in silc_hash_table_free.
3381 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3382 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3383 into the lib/silcutil/silcutil.[ch].
3385 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3387 * Implemented a collision resistant hash table into the
3388 lib/silcutil/silchashtable[ch]. See the header and the source
3389 for the SilcHashTable API.
3391 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3393 * Merged dotconf version 1.0.2 into lib/dotconf.
3395 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3397 * Do not compile anything in lib/silcsim/* if the SIM support
3398 is not enabled. The tree should now compile without problems
3401 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3403 * Compiled the SILC under cygwin. Compiled and tested briefly
3404 without problems. More tests needed. The SIMs didn't compile
3407 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3409 * Fixed possible crash in silc_get_username in the
3410 lib/silcutil/silcutil.c.
3412 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3414 * Fixed a va_arg in silc/client_ops.c.
3416 * Oops, RC5 routines were named AES and caused some problems
3417 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3419 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3421 * Added new SilcIDIP structure into the lib/silccore/id.h and
3422 replaced the old `ip' fields from all SILC ID's to that type.
3423 This is a step towards IPv6 support.
3425 The silc_id_get_len takes now the ID as an extra argument.
3426 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3427 both IPv4 and IPv6 based ID's.
3429 The affected files are lib/silccore/id.[ch] and other files
3430 around the tree using these routines.
3432 * Removed the ID length arguments in server from various
3433 silc_server_send_notify_* routines -> they are not needed
3436 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3438 * Fixed memory leak in silc_encode_pem_file in the file
3439 lib/silcutil/silcutil.c.
3441 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3443 * Check minor version as well in the SKE. Affected files are
3444 silcd/protocol.c and lib/silcclient/protocol.c.
3446 * Added --identifier option to the server so that an identifier
3447 can be when creating the public key for the server. Affected
3448 file is silcd/silcd.c.
3450 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3451 lib/silccrypt/silcpkcs.c.
3453 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3455 * Register default ciphers and stuff when using -C option with
3456 the server. Affected file sildc/silcd.c.
3458 * Put back the servers public key filename format, it is better
3459 than the new one. For now, the client keys are saved with the
3460 new filename format. The affected file silc/client_ops.c.
3462 * Implemented the Cipher API for the rest of the ciphers that
3463 did not implement it or implemented it the wrong way.
3465 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3467 * Register default ciphers and stuff when using the -S option
3468 in the client. Affected file silc/silc.c. Same also when
3469 creating new key pair with -C option.
3471 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3473 * Fixed the silc_verify_public_key client operation function to
3474 save the public keys differently. The fingerprint is now
3475 used as filename and not the hostname. This way also the
3476 client keys are saved uniquely and not with hostnames. The
3477 affected file is silc/client_ops.c.
3479 * Trimmed the silc_hash_fingerprint function to remove extra
3480 whitespaces from the end of the fingerprint. The affected
3481 file is lib/silccrypt/silchash.c.
3485 * Added silc_cipher_register_default function to register all
3486 default ciphers. It can be used when configuration files
3487 does not exist and the application does not want any specific
3488 ciphers in any specific order.
3490 The SilcDList is now used as silc_cipher_list dynamically
3491 allocated cipher list. Removed the static list all together
3492 and now all ciphers must be allocated to the dynamic list.
3493 The silc_cipher_alloc routine was changed to check only the
3496 All silc_cipher_* routines that used to return int returns
3499 The affected files lib/silccrypt/silccrypt.[ch].
3501 * The same thing was done to silc_hash_* as for silc_cipher_*
3502 routines. Affected files lib/silccrypt/silchash.[ch].
3504 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3505 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3506 Added also silc_pkcs_[un]register[_default] functions.
3507 Removed the data_context from the PKCS API.
3509 * Added silc_hmac_register_default function to register default
3510 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3511 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3512 to unregister all hmacs at once.
3514 * Register the default ciphers, hash functions, PKCSs and HMACs
3515 if client's configuration file does not exist. The affected
3518 * The client did not load the hash functions from the SIM
3519 modules at all. Added support for this. Affected file is
3520 silc/clientconfig.c.
3522 * When decoding public key with silc_pkcs_public_key_decode, check
3523 the supported algorithm only if PKCS are registered. Affected
3524 file lib/silccrypt/silcpkcs.c. The same was done with the
3525 silc_pkcs_private_key_decode.
3527 * Fixed the SILC List routines to keep the list always in order.
3528 It used to change the list's order when traversing the list but
3529 not it preserves the order. Affected file lib/trq/silclist.h.
3531 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3533 * Added the client library to use the SilcSocketConnection's
3534 reference counter (by silc_socket_dup) to prevent the bug that
3535 the socket object may be freed underneath async operation.
3537 * The name resolv library checking fixes in the configure.in.pre.
3540 * Created new version of the protocol drafts for future
3541 development. The -03 drafts are the ones that will be changed
3542 in the trunk now and the -02 will remain as they are.
3544 * Send list of CUMODE notifys to the router when announcing
3545 the channel users to the router. Affected file silcd/server.c.
3546 If the router receiving channel founder CUMODE for a channel
3547 that already has channel founder it will send CUMODE notify
3548 to the sender to remove the channel founder rights from the
3549 announced client. Affected file silcd/packet_receive.c.
3551 * The CUMODE notify may now use Server ID as well as the entity
3552 who changes the mode. Updated protocool specs.
3554 * Updated INSTALL and README files.
3556 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3558 * New web pages in the http://silc.pspt.fi. The pages was
3563 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3565 * Implemented the [DenyConnectin] config section in the server.
3566 Added silc_server_config_denied_conn to check whether incoming
3567 connection is denied. Affected file silcd/serverconfig.[ch].
3569 * Do not check the ports when checking the incoming configuration
3570 data if the port is 0, meaning any. Affected file is
3571 silcd/serverconfig.c.
3573 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3575 * Fixed buffer overflow in silc_string_compare in the file
3576 lib/silcutil/silcutil.c.
3578 * Fixed double free in silc_server_command_leave in the file
3581 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3583 * Fixed the version checking in the server. Affected file is
3586 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3588 * Fixed the configuration data fetching when accepting new
3589 connections in the server. Affected file silcd/server.c.
3591 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3593 * Added `sender_entry' argument to the function
3594 silc_server_packet_relay_to_channel so that we can check
3595 whether some destination actually belongs to the same route
3596 the sender belongs (ie, we must not resend the packet to the
3597 sender). Affected file silcd/packet_send.[ch].
3599 * Added `servername' field to the SilcClientEntry in the server
3600 to hold the name of the server where client is from. Affected
3601 file is silcd/idlist.h.
3603 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * Moved the channel message encrypting in the router betwen
3606 router connections from silc_server_channel_message to the
3607 silc_server_packet_relay_to_channel since we want to check
3608 whether we have anybody channel before encrypting anything.
3609 Affected files silcd/packet_[receive/send].c.
3611 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Fixed the [AdminConnection] server config section to support
3614 multiple entries. Affected file silcd/serverconfig.c.
3616 * Added support into the server to check the validity of the
3617 incoming connection before executing any KE or authentication
3620 * The connection configuration is now saved to the KE and
3621 connection auth protocol contexts and not fetched anymore in
3622 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3624 * The local hosts listenning address and port is also resolved
3625 now when starting the server. We want to have the socket object
3626 to include the real address and port for the listener. Added
3627 new function silc_net_check_local_by_sock into the files
3628 lib/silcutil/silcnet.[ch].
3630 * Fixed a broadcast bug in server -> do not broadcast if we
3633 * Fixed a routing bug. Do not route broadcast packets ever.
3634 Broadcast packets must be processed always and not routed since
3635 they may be destined to some other host than yourself and thus
3636 would get routed without no good reason. Affected file is
3639 * Added function silc_server_config_is_primary_route to check
3640 whether primary router connection has been configured (a router
3641 configuration that we are initiating). If there is not, we
3642 will assume that there is only two routers in the SILC network
3643 and we will use the incoming router connection as our primary
3644 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3646 * Changed the order of the broadcasting. Broadcast _after_ the
3647 packet has been processed not before. Affected file is
3650 * Fixed a [ClientConnection] parsing bug. The port was never
3651 parsed correctly thus resulting to port 0. Affected file
3652 silcd/serverconfig.c.
3654 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3655 argument and did not set the broadcast packet flag. Affected
3656 file silcd/packet_send.c. Fixed same bug in the function
3657 silc_server_send_notify as well.
3659 * If we receive NEW_ID packet for our own ID in the server, ignore
3662 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3666 * Removed the nickname from the Private Message Payload.
3667 Updated the code and the protocol specs.
3669 * Updated protocol specs for submitting to the IETF.
3671 * Tweaked the Random Number Generator a bit. Affected file
3672 lib/silccrypt/silcrng.c. Exported a new function
3673 silc_rng_[global]_add_noise which can be used to add more
3676 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * Do not parse packets with different timeout when protocol
3679 is active -> may cause problem with rekey. Affected file
3682 * When server receives signoff notify it must not create
3683 new channel key if the client is on any channels since the
3684 sender of the signoff notify will create it.
3686 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3688 * Added printing of error messages during SKE protocol from the
3689 failure packet sent by server during SKE. Affected file
3692 * Removed the client's failure_callback handling with timeout
3693 and handle it immediately when received.
3695 * The SKE library returned wrong type in SUCCESS and FAILURE
3696 packets. They must be 32 bit MSB not 16 bit MSB.
3698 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3700 * Ok, rewrote the logic of the re-key and now it seems to work.
3701 I tested it on high traffic with frequent re-keys without
3702 problems. Added hmac_receive (and renamed hmac to hmac_send)
3703 in SilcClientConnection in lib/silcclient/client.h and
3704 in SilcIDListData in silcd/idlist.h. Also, removed the
3705 SilcPacketParserContext's cipher and hmac fields as they are
3706 not needed anymore and actually caused some problems when
3707 the ciphers and hmac's changed underneath the packet parser.
3709 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3711 * If re-key protocol is active then process the incoming packets
3712 synchronously since we must assure that icoming packets encrypted
3713 with the old key is processed before the new keys is set to
3714 use. This is true other packets than for REKEY packets.
3715 Affected file silcd/server.c. The same was done to client library
3716 as well, affected file lib/silcclient/client.c.
3718 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Fixed bug in client and server to accept the force send if
3721 the packet is send from silc_[server/client]_packet_process
3722 function. Otherwise the packets are never delivered, oops.
3724 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3726 * Disable force sending of packets when REKEY protocol is active.
3727 We must assure that no packet is sent directly when rekey is
3728 performed. All packets must be sent through packet queue.
3729 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3730 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3731 function is silc_[server/client]_packet_send_real to check
3734 * Replaced the SIM paths from example config files to
3735 /usr/local/modules. Also, make install creates now
3736 /usr/local/silc/logs directory to hold all the SILC server
3739 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3741 * Made the configure.in.pre work on Solaris. Patch by salo.

3750 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3752 * When MAC computation fails the silc_packet_decrypt returned 0
3753 even though it was supposed to return -1. Fixed this. The
3754 affected file is lib/silccore/silcpacket.c.
3756 * Do not replace the config files in /etc/silc (in make install)
3757 if they already exist. Affected file ./Makefile.am.
3759 * Do not send re-key packets immediately but through packet queue.
3760 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3762 * Changed silc_net_check_host_by_sock to return FALSE if the
3763 IP/DNS could not be resolved. Though, it returns the IP address
3764 now even if it could not resolve it (but returns also FALSE).
3765 Affected file lib/silcutil/silcnet.[ch].
3767 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3769 * Added silc_pkcs_decode_identifier to decode the public key's
3770 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3771 Added also silc_pkcs_free_identifier. Added also new context
3772 SilcPublicKeyIdentifier.
3774 * Added -S option to the silc client. It is used to dump the
3775 contents of the specified public key file.
3777 * Changed the PKCS api to return the public key length when
3778 setting the public key.
3780 * Fixed a fatal bug in the public and private key file loading.
3781 Affected file lib/silccrypt/silcpkcs.c.
3783 * Execute the packet parsing for client with zero (0) timeout
3784 if the protocol is active. Affected file silcd/server.c.
3786 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3788 * Made the key generation options to the silcd program. Added
3789 -C option, equivalent to client's option.
3791 * Added new [ServerKeys] config section to the server. It
3792 configures the server's public and private key.
3794 * Defined generic Public Key Payload into the protocol
3795 specification to send specific type of public keys and
3798 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3799 public key or certificate.
3801 * Implemented the GETKEY command to the server and to the
3802 client library and on user interface.
3804 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3806 * Made preliminary `make install' work.
3808 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3810 * Added SilcServerRekey context into silcd/idlist.h.
3812 * Added the PFS support as defined in the specification to the
3813 SKE protocol. Affected files lib/silcske/*.c.
3815 * Added `ske_group' field to the SilcServerRekey context to hold
3816 the number of the SKE group that is used with PFS in re-key.
3817 Affected file silcd/idlist.h.
3819 * Added PFS re-key support to the server. Affected file is
3822 * Added silc_protocol_cancel to cancel execution of the next
3823 state of the protocol. Affected file is
3824 lib/silccore/silcprotocol.[ch].
3826 * Added the re-key support with and without PFS to the client
3827 library. Re-key is performed once in an hour, by default.
3829 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3830 Added silc_client_rekey_callback and silc_client_rekey_final.
3831 Affected files are lib/silcclient/protocol.[ch] and
3832 lib/silcclient/client.[ch].
3834 * Removed the `hmac_key' and `hmac_key_len' fields from the
3835 SilcClientConnection structure; not needed. Affected file is
3836 lib/silcclient/client.h.
3840 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3842 * Do not ask whether user wants to use the negotiated private key
3843 for private messages, just use it. Affected file is
3844 silc/local_command.c.
3846 * Added `send_enc_key' and `enc_key_len' fields to the
3847 SilcIDListData structure since they are needed in the re-key
3848 phase. Affected file is silcd/idlist.[ch].
3850 * Implemented the simple re-key protocol into the server.
3851 Affected files silcd/server.c and silcd/protocol.[ch]. The
3852 re-key will be performed once in an hour, by default.
3854 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3855 Added silc_server_rekey, silc_server_rekey_callback and
3856 silc_server_rekey_final.
3858 * Removed Tunneled flag from the protocol. Updated the code
3859 and the specifications.
3861 * Adde `pfs' field to the SilcIDListData to indicate whether
3862 the PFS is to be performed in the re-key. Affected file is
3865 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3868 int64 of at least the xintXX size. If void * is less that 4
3869 bytes uint32 * will be used. Defined bool as boolean.
3871 * Changed _ALL_ unsigned long and unsigned int to uint32,
3872 unsgined short to uint16 in the source tree.
3874 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3875 not handle clients that has entry->data.registered == FALSE.
3876 They are not in the network anymore. Affected file is
3879 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3881 * Implemented the sending of the SERVER_SIGNOFF notify in the
3882 server. Affected file is silcd/server.c.
3884 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3885 Added also silc_notify_payload_encode_args into the
3886 lib/silccore/silcnotify.[ch].
3888 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3889 Affected file silcd/packet_receive.c.
3891 * Implemented the SERVER_SIGNOFF notify handling in the client
3892 library. Affected file lib/silcclient/client_notify.c. Also,
3893 implemnted the printing of the SERVER_SIGNOFF info to the
3894 application. Affected file silc/client_ops.c.
3896 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3897 if the deleting was successful. Affected file silcd/idlist.[ch].
3899 * Added support for public key authentication in the connection
3900 authentication protocol in the client library. Affected file
3901 lib/silcclient/protocol.c.
3903 * Changed the server's silc_idlist_get_clients_by_* interface
3904 to support already allocated array so that new entries may be
3905 added to pre-allocated array. Affected file silcd/idlist.[ch].
3906 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3907 and command replies.
3909 * All command reply functions in the server now calls the
3910 pending command callback even if error occured. This way the
3911 error will be delivered to the client as well. Affected files
3912 silcd/command.c and silcd/command_reply.c.
3914 * Fixed INFO command to return local server's info if no server
3915 was provided. Affected file lib/silcclient/command.c.
3917 * Removed RESTART command for good. Updated the code and the
3920 * Rewrote parts of the task system. It is a bit simpler now.
3921 Removed unsued task priorities. The affected files are
3922 lib/silcutil/silctask.[ch].
3924 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3926 * Moved the USERS printing from the library to the application.
3927 Affected files lib/silcclient/command.c and silc/client_ops.c.
3929 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3933 * Added channel key re-key support. The re-key is perfomed
3934 only by the router and is done once in an hour. Added `rekey'
3935 field to the SilcChannelEntry in the server. Affected files
3936 silcd/server.c and silcd/idlist.h.
3938 * Added silc_task_unregister_by_context into the file
3939 lib/silcutil/silctask.[ch].
3941 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3943 * Added SILC_UMODE_GONE mode to indicate when the client is not
3944 present in the SILC network. Added also support to the local
3945 command AWAY that will set this mode. Added support of showing
3946 "xxx is gone" in WHOIS command. The USERS command shows the
3947 gone status as well.
3949 * Fixed setting server and router operator privileges in the
3950 server's UMODE command. Affected file silcd/command.c.
3952 * Merged the SKE KE1 and KE2 payloads into one payload. The
3953 new KE payload is equivalent to the old KE2 payload.
3955 Cleaned up the SKE Start Payload parsing. It now uses the
3956 simple buffer unformatting to do the parsing. A lot faster
3959 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3960 to the SKE that is used to indicate whether both of the SKE
3961 parties should perform authentication. By default only the
3962 responder performs authentication. By setting this flag also
3963 the initiator must do authentication. By default it is unset
3964 since in normal SKE case, client to server connection, only
3965 the responder should do authentication. When doing SKE between
3966 two clients both should perform authentication. Updated the
3967 code and the protocol specs.
3969 * A little fix to IDENTIFY command in the server. Search the
3970 client first by hash not nickname. Affected file is
3973 * Fixed the silc_client_close_connection to support closing
3974 the client to client connections wihtout deleting too much
3975 data. Affected file lib/silcclient/client.c.
3977 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3978 are received if protocol used to be active but is not anymore
3979 the application would crash due to NULL pointer dereference.
3980 Affected files silcd/server.c and lib/silcclient/client.c.
3982 * Added `hash' field to the SilcClientConnection to include
3983 the hash function negotiated in the SKE protocol.
3985 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3986 to set the channel founder authentication data. A client can
3987 claim the founder rights later by providing the authentication
3988 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3989 This way the channel founder can regain the channel founder
3990 privileges even it is left the channel. This works only on
3991 local server and the client must be connected to the same
3992 server to be able to regain the founder rights. Updated the
3993 protocol specs accordingly.
3995 Added support to the CMODE command in the client to set the
3996 founder auth data. Read the README to see how to set it.
3998 Added support to the CUMODE command to claim the founder
3999 rights. Read the README to see how to do it.
4001 Added support for the founder authentication to the Channel
4002 Entry in the server. Affected file silcd/idlist.h.
4004 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4005 server's CMODE command. Affected file silcd/command.c.
4007 * Added the following new functions into lib/silccore/silcauth.[ch]:
4008 silc_auth_get_method and silc_auth_get_data.
4010 * The server now saves the remote hosts public key to the
4011 SilcIDListData pointer. Affected file silcd/protocol.c.
4013 * The normal server now does not remove the channel entry from
4014 the cache if the founder authentication data is set. It used
4015 to remove it if the founder was the last one on the channel on
4016 the server and left the channel. The auth data is saved and
4017 if the channel is re-joined later the old entry is used with
4018 the old auth data. Affected files silcd/command_reply.c and
4021 * Removed the `pkcs' field from the SilcIDListData structure
4022 in the server; it is not used. Affected file silcd/idlist.h.
4024 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4026 * Fixed packet processing on slow links. Partial packets were
4027 never re-processed because the incoming data buffer was cleared
4028 by the application. Application must not directly clear the
4029 sock->inbuf, the packet processing routines handle it. Fixed
4030 this in client library and in server.
4032 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4034 * Fixed the WHOIS and IDENTIFY send reply function to really
4035 check whether to send list or just one entry. Affected file
4038 * Cleaned up the LEAVE command's channel key distribution. The
4039 affected file silcd/command.c.
4041 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4042 can enforce the channel mode as well. In that case the ID
4043 includes the ID of the server. The code now enforces the
4044 mode change if the router have different mode than the server.
4046 * The notify client operation with CMODE_CHANGE notify can now
4047 return NULL client_entry pointer if the CMODE was not changed
4048 by client. Application must check for this.
4050 * Added <Server ID> argument to INFO command to support server
4051 info fetching by Server ID.
4053 * Added silc_server_announce_get_channel_users to get assembled
4054 packets of channel users of the specified channel. Affected
4055 file silcd/server.[ch].
4057 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4058 was freed underneath the ID Cache.
4060 * Re-announce clients when the server received CHANNEL_CHANGE
4061 notify from the router. Affected file silcd/packet_send.c.
4063 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4065 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4066 crashed since it did not handle the fact that there is no cipher
4067 called "3" and didn't check the error condition. Now fixed.
4069 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4070 flag. It can be used to send message requests.
4072 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4074 * Implemented the RESTART command in the client.
4076 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4077 notice type messages. Added notice printing to the user
4080 * The channel keys are not re-generated if the channel's mode
4081 is PRIVKEY, ie private key on the channel exists. Affected
4082 files silcd/server.c and silcd/command.c.
4084 * Fixed a little bug in channel message delivery when channel
4085 private keys are set in the server. Affected file is
4086 silcd/packet_send.c.
4088 * Changed the setting on channel->on_channel = TRUE from the
4089 silc_client_save_channel_key to the JOIN command reply. The
4090 key payload is not received if the private channel key is set.
4091 Affected file lib/silcclient/command_reply.c and the
4092 lib/silcclient/client_channel.c.
4094 * When the CMODE_CHANGE notify is sent and the channel private
4095 key mode is removed the channel key must be re-generated in
4096 other cells as well. Added this support for the router in the
4097 silcd/packet_receive.c.
4099 * Added new local command NOTICE to send notice message on
4100 channel. Affected file silc/local_command.[ch].
4102 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Added new local command ME to the client. It is used to send
4105 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4106 some action. Affected file silc/local_command.[ch].
4108 * Changed channel_message and private_message client operations
4109 to deliver the message flags to the application. Added also
4110 the `flags' arguments to the silc_client_send_channel_message
4111 and silc_client_send_private_message functions. Affected file
4114 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4116 * Redefined the Private Message Payload to support private message
4117 keys and to support the new private message flags. Updated
4118 the protocol specs. Flags makes it possible to have for example
4119 CTCP style messages.
4121 * Added new type SilcPrivateMessagePayload and defined an API
4122 for it in the lib/silcclient/silcprivate.[ch].
4124 * Tested private message private keys successfully. Tested the
4125 private message key set, unset and list commands with the new
4128 * Redefined the Channel Message Payload to include the channel
4129 message flags (equal with private message flags) to support
4130 for example CTCP style messages.
4132 * Defined some of the message (for channel and private message)
4133 flags. Updated the protocol specs and added the flags to the
4134 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4136 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Added SilcKeyAgreementStatus type to the key agreement routines
4139 to indicate the current status and error if one occured.
4140 The status types are defined in the lib/silcclient/silcapi.h.
4142 * Added new local command KEY that is used to set and unset private
4143 keys for channels, set and unset private keys for private messages
4144 with remote clients and to send key agreement requests and
4145 negotiate the key agreement protocol with remote client. The
4146 key agreement is supported only to negotiate private message keys,
4147 it currently cannot be used to negotiate private keys for channels,
4148 as it is not convenient for that purpose.
4150 * Fixed a minor pending callback setting bug in the function
4151 silc_client_get_client_by_id_resolve, now the function works.
4152 Affected file lib/silcclient/idlist.c.
4154 * Added function silc_net_get_local_port to get local bound
4155 port by socket. Added to lib/silcutil/silcnet.[ch].
4157 * Added `sockets' and `sockets_count' fields to the SilcClient
4158 object. They hold the sockets of the listenning sockets in
4159 the client. Listenning sockets may be for example the key
4160 agreement server. Affected file lib/silcclient/client.[ch].
4161 Added functions the silc_client_add_socket and the
4162 silc_client_del_socket. They are exported to the application
4165 * Added ~./silc/clientkeys to support other client's public keys.
4167 * Renamed verify_server_key client operation to verify_public_key
4168 and added one argument to indicate the type of the connection
4169 (server, client etc.).
4171 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4173 * Added silc_server_connection_auth_request to handle the
4174 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4175 silcd/packet_receive.[ch].
4177 * Added silc_server_send_connection_auth_request into the
4178 silcd/packet_send.c to send the connection auth request packet.
4180 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4183 * Fixed the public key authentication in responder side in the
4184 server. The `auth_data' pointer includes the SilcPublicKey
4185 not the path to the public key. Affected file silcd/protocol.c.
4187 * Implemented the public key authentication in the initiator side
4188 in the server. Affected file silcd/protocol.c.
4190 * Removed the [RedirectClient] config section from the server
4191 configuration. Is not needed and I don't want to implement it.
4193 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4195 * Cleaned up the CMODE command in the server. It now works
4196 correctly and supports all the modes defined in the protocol.
4197 Affected file is silcd/command.c.
4199 * Added `hmac_name' field to the SilcChannelEntry in the server
4200 to hold the default HMAC of the channel. It can be set when
4201 creating the channel (with JOIN command). Affected files
4204 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4205 type to indicate the change of the current cipher and hmac
4206 on the channel. Client can safely ignore the <cipher> argument
4207 (if it chooses to do so) since the CHANNEL_KEY packet will
4208 force the channel key change anyway. The <hmac> argument is
4209 important since the client is responsible of setting the new
4210 HMAC and the hmac key into use.
4212 * Fixed the CMODE command in the client library as well.
4214 * Tested CMODE command in router environment successfully.
4216 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4218 * Show the version of the remote client (or server) when connecting
4219 to the server. It is logged to the log file. Affected file
4220 is silcd/protocol.c.
4222 * Fixed the KILLED notify handling in the client library. The
4223 client must be removed from all channels when receiving the
4226 Also, do not remove the client entry when giving the KILL
4227 command but when the KILLED notify is received.
4229 * Removed silc_idlist_find_client_by_nickname from the server.
4230 Not needed anymore. Affected files silcd/idlist.[ch].
4232 * Implemented the CHANNEL_CHANGE notify type handling to the
4233 server. Affected file silcd/server.c.
4237 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4239 * Added silc_server_send_notify_invite to send the INVITE
4240 notify between routers.
4242 * Implemented the INVITE command correctly to the server.
4244 * Implemented the INVITE notify type handling in the server.
4246 * Implemented the INVITE command to the client library and on the
4249 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Added function silc_server_get_client_resolve to find the
4252 client entry by ID from all ID lists and then resolve it
4253 (using WHOIS) if it cannot be found. Affected file is
4256 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4258 * Implemented the BAN command to the client library.
4260 * The JOIN command in the server now checks the invite list
4263 * Changed the silc_command_reply_payload_encode_va and the
4264 silc_command_payload_encode_va to support that if argument is
4265 NULL it ignores and checks the next argument. Affected file
4266 lib/silccore/silccommand.c.
4268 * Added silc_server_send_notify_ban to send the BAN notify
4269 type between routers.
4271 * Chaned the silc_notify_payload_encode to support that if
4272 argument is NULL it ignores and checks the next argument.
4273 Affected file lib/silccore/silcnotify.c.
4275 * Tested ban lists in router environment successfully.
4277 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4279 * Implemented BAN command to the server, in silcd/command.[ch].
4281 * Removed the BAN and INVITE_LIST modes from the CMODE command
4284 * Added function silc_string_match to regex match two strings.
4285 Affected files lib/silcutil/silcutil.[ch].
4287 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4289 * Redefined parts of the SilcChannelEntry in the server to support
4290 the new ban and invite lists.
4292 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4294 * Redefined the INVITE command. The same command can be used to
4295 invite individuals to the channel but also to manage the invite
4296 list of the channel (to add to and remove from the invite list).
4297 Updated the protocol specs.
4299 * Added new command SILC_COMMAND_BAN that can be used to manage
4300 the ban list of the channel. Updated the protocol specs.
4302 * Removed the channel modes: the SILC_CMODE_BAN and the
4303 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4304 in the CMODE command. The equivalent features are now available
4305 using INVITE and BAN commands. Updated the protocol specs.
4307 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4308 in the network about change in the current ban list. The notify
4309 type is not used by the client.
4311 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4312 support the invite lists.
4314 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4316 * Added new function silc_string_regexify that converts string
4317 including wildcard characters into regex string that can
4318 be used by the GNU regex library. Added into the file
4319 lib/silcutil/silcutil.[ch].
4321 Added silc_string_regex_combine to combine to regex strings
4322 into one so that they can be used as one regex string by
4323 the GNU regex library. Added into the file
4324 lib/silcutil/silcutil.[ch].
4326 Added silc_string_regex_match to match two strings. It returns
4327 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4329 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4331 * Imported GNU regex to the soruce tree into lib/contrib.
4332 Fixed some compiler warning from the regex.c.
4334 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4336 * Fixed MOTD command in the server to work in router environment.
4338 * Fixed the MOTD command in the client library to support
4339 the server argument in the command.
4341 * Added `nickname_len' argument to the silc_idlist_add_client
4342 in the server, as the `nickname' argument may be binary data
4345 * Added silc_idlist_get_channels to return all channels from
4348 * Implemented LIST command to the server. Affected file is
4351 * Implemented the LIST command to the client library and on the
4354 * Added [<user count>] argument to the LIST command reply.
4355 With private channels the user count is not shown.
4357 * Updated TODO and README.
4359 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4361 * The client entry's data.registered must be TRUE even with
4362 global client entry on global client list. The data.registered
4363 is used to check whether the client is anymore in the network,
4364 for example with WHOWAS command so it must be valid.
4366 * Fixed the WHOWAS command in the server. It now actually works
4367 in router environment. Added function into silcd/command_reply.c
4368 silc_server_command_reply_whowas_save.
4370 * Added silc_idlist_purge function to the silcd/idlist.c
4371 to periodically purge the ID Cache.
4373 * Fixed INFO command in the server. It works now in router
4374 environment. Added <server name> argument to the INFO command
4375 reply. Updated the protocol specs.
4377 * Fixed minor bug in silc_idcache_purge to not purge if the
4378 expire value is zero.
4380 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4381 they were buggy because of the WHOWAS information.
4383 * Fixed local command MSG to handle the async resolving of
4384 the remote client properly. It used to fail the first MSG.
4385 Affected file silc/local_command.c.
4387 * Added `data_len' field to SilcIDCache context.
4389 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4391 * Update TODO. Todo in commands in the server.
4393 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4396 used by routers as broadcast packet to inform other routers
4397 about the changed user mode.
4399 Implemented the notify handling in the server. Affected file is
4400 silcd/packet_receive.c. Added the function
4401 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4403 * Added new generic Channel Payload and deprecated the New Channel
4404 Payload. The New Channel Payload is now the generic Channel
4407 * Added new argument `mode' to the silc_server_send_new_channel
4408 as it is required in the Channel Payload now.
4410 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4411 and created a new and real SilChannelPayload to represent the
4412 new generic Channel Payload. Implemented the encode/decode
4413 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4415 * Added silc_server_get_client_channel_list to return the list
4416 of channels the client has joined for WHOIS command reply.
4417 Affected file silcd/server.[ch].
4419 * Implemented the channel list sending in the WHOIS command reply
4420 in server and in the client.
4422 Implemented the channel list displaying on the user interface
4423 as well. Affected file silc/client_ops.c.
4425 * Added silc_channel_payload_parse_list to parse list of Channel
4426 Payloads. It returns SilcDList list of SilcChannelPayloads.
4427 Client for example can use this function to parse the list of
4428 channels it receives in the WHOIS command reply. The caller
4429 must free the list by calling silc_channel_payload_list_free.
4430 Affected files lib/silccore/silcchannel.[ch].
4432 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4434 * Added one new argument <user mode> to the WHOIS command reply
4435 to return the mode of the user in SILC. Updated the protocol
4438 Implemented it to the server and client.
4440 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4442 * Fixed the mode printing on the user interface on joining.
4443 Affected file silc/client_ops.c.
4445 * Implemented the UMODE command and user modes in general to the
4446 client library and to the user interface.
4448 * Implemented the UMODE command to the server.
4450 * The server now sends UNKNOWN_COMMAND error status if client sends
4451 unknown command. Affected file silcd/command.c.
4453 * All server commands now handle the command identifier the right
4454 way when sending the command reply to the client. The client can
4455 use to identify the command replies with the identifier.
4457 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4459 * Added silc_server_get_client_route to resolve the route to
4460 the client indicated by the client ID. Affected file is
4463 * Added silc_server_relay_packet as general function to relay
4464 packet to arbitrary destination. This deprecates functions
4465 like _send_private_message_key, _relay_notify etc. Affected
4466 file is silcd/packet_send.[ch].
4468 Removed silc_server_send_key_agreement,
4469 silc_server_send_private_message_key and
4470 silc_server_packet_relay_notify functions from the file
4471 silcd/packet_send.[ch].
4475 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4476 server. Affected file silcd/packet_receive.[ch].
4478 * Implemented the KILL command to the client. Implemented the
4479 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4480 Affected files lib/silcclient/command[_reply].c and
4481 lib/silcclient/client_notify.c. Implemented the KILL notify
4482 printing in the user inteface.
4484 * Fixed a lot silc_parse_nick memory leaks from the client
4485 library in the file lib/silcclient/command.c.
4487 * Changed the silc_server_send_notify_on_channels's `sender'
4488 argument from SilcSocketConnection to SilcClientEntry to
4489 check the sender as entry and not as connection object and not
4490 to send to the client provided as argument. The affected file
4491 is silcd/packet_send.[ch].
4493 * The notify packets that are destined directly to the client used
4494 to not to be processed by the server. Now changed that and the
4495 server processes all notify packets. After relaying the packet
4496 to the client the notify packet is processed in the server.
4498 * The silc_server_free_client_data now checks whether there is
4499 pending outgoing traffic for the client and purges the data to
4500 the network before removing the client entry.
4502 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4505 an client is killed from the SILC Network. Updated the protocol
4508 Added new function silc_server_send_notify_killed to the
4509 silcd/packet_send.[ch].
4511 * Added function silc_server_packet_relay_notify to relay notify
4512 packets that are destined directly to a client. In this case
4513 the server does not process the notify packets but merely relays
4514 it to the client. Affected file silcd/packet_send.[ch].
4516 Added also silc_server_packet_process_relay_notify to check
4517 whereto relay the notify. Affected file is
4518 silcd/packet_receive.[ch].
4520 * Implemented the KILL command to the server.
4524 * Added the backup schema desgined last fall to the protocol
4525 specs for everyone to see. The specification is in the
4526 *-spec-xx.txt draft and the packet type definitions for the
4527 backup routers is in *-pp-xx.txt draft. Thusly, added also
4528 new packet type SILC_PACKET_CELL_ROUTERS.
4530 * A big security problem in the implementation discovered. The
4531 signoff of an client did not cause new channel key generation
4532 which it of course should've done. The channel keys must be
4533 always re-generated when client leaves (or signoffs) the channel.
4534 The silc_server_remove_from_channels funtion now handles
4535 the channel key re-generation.
4537 * Added `sender' argument to the silc_server_send_notify_on_channels
4538 to not to send the client provided as argument. Affected file
4539 silcd/packet_send.[ch].
4541 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4543 * Implemented OPER and SILCOPER commands into the server and
4546 * Added silc_auth_verify and silc_auth_verify_data to verify
4547 the authentication directly from the authentication payload.
4548 It supports verifying both passphrase and public key based
4549 authentication. Affected file lib/silccore/silcauth.[ch].
4551 * Added `hash' field to the SilcIDListData structure. It is the
4552 hash negotiated in the SKE protocol. Affected file is
4555 * Slight redesigning of the SilcAuthPayload handling routines.
4556 Do not send SilcPKCS but SilcPublicKey as argument.
4558 * Implemented the public key authentication support to the
4559 serverconfig. The public key is loaded from the provided path
4560 and saved as authentication data to void * pointer. Thus,
4561 changed the unsigned char *auth_data to void *auth_data;
4563 * Fixed SHUTDOWN command to send the reply before the server
4564 is shutdown. :) Affected file silcd/command.c.
4566 * Fixed fatal bug in CONNECT command. The hostname was invalid
4567 memory and server crashed. Affected file silcd/command.c.
4569 * Fixed fatal bug in CLOSE command. The server_entry became
4570 invalid but was referenced later in the command. Affected file
4573 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Fixed fatal bug in failure packet handling. Server ignored
4576 the failure and thus crashed when it came.
4580 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4582 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4583 that the command may be executed only once in (about) 2 seconds.
4584 The old SILC_CF_LAG flag is same but allows command bursts up
4585 to five before limiting.
4587 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4588 server code. Various commands now includes the CF_LAG_STRICT
4589 flag to disallow any kind of miss-use of the command.
4591 * Fixed the silc_buffer_unformat to not to allocate any data
4592 if the length of the data is zero. It used to allocate the
4593 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4595 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Changed the format of AdminConnection configuration section
4598 in the server. Added username of the admin to the format.
4599 Affected files silcd/serverconfig.[ch].
4601 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4602 to return admin configuration data by host, username and/or
4605 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4607 * Implemented WHOWAS command to the server. Added the functions:
4609 silc_server_command_whowas_parse,
4610 silc_server_command_whowas_send_reply,
4611 silc_server_command_whowas_from_client and
4612 silc_server_command_whowas_from_server
4614 * Added <Client ID> argument to the WHOWAS command reply. Updated
4615 the protocol specs accordingly.
4617 * Implemented WHOWAS command and command_reply to the client
4620 Implemented the WHOWAS printing on the user interface.
4622 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4624 * Added new argument to the WHOWAS command reply, the real name.
4625 It is an optional argument. Updated the protocol specs.
4627 * Added SilcIDCacheDestructor callback that is registered when
4628 the SilcIDCache is allocated. The callback is called when
4629 an cache entry in the ID Cache expires, or is purged from the
4630 cache. Added into lib/silccore/idcache.[ch].
4632 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4633 to destruct the client entries when the cache entry expires.
4634 Other ID Cache's in server and in the client library ignores
4637 * If the ID Cache entry's `expire' field is zero then the entry
4638 never expires. Added boolean `expire' argument to the
4639 silc_idcache_add function in the lib/silccore/idcache.[ch].
4640 If it is TRUE the default expiry value is used.
4642 * Added silc_server_free_client_data_timeout that is registered
4643 when client disconnects. By default for 5 minutes we preserve
4644 the client entry for history - for WHOWAS command.
4646 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4648 * Added support to the server to enforce that commands are not
4649 executed more than once in 2 seconds. If server receives
4650 commands from client more frequently, timeout is registered
4651 to process the commands. Affected file silcd/command.c.
4652 Added new function silc_server_command_process_timeout.
4654 * Changed NICK_NOTIFY handling in client library to check that
4655 if the client's nickname was changed, so there is no need to
4656 resolve anything from the server.
4658 * Removed error printing from the WHOIS and IDENTIFY commands.
4659 If error occurs then it is ignored silently in the client library.
4660 The application, however, may map the received error to
4661 human readable error string. The application currently maps
4662 the NO_SUCH_NICKNAME error to string.
4664 * Made the command status message public to the application. Moved
4665 them from lib/silcclient/command_reply.c to
4666 lib/silcclient/command_reply.h. The application can map the
4667 received command status to the string with the
4668 silc_client_command_status_message function.
4670 * Added check to the server to check that client's ID is same
4671 as the Source ID in the packet the client sent. They must
4674 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Added dist-bzip hook to the Makefile.am to make bzip2
4677 compressed distributions.
4679 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Server now enforces the maximum length for the nickname and
4682 the channel as protocol specification dictates. 128 bytes for
4683 nickname and 256 bytes for channel name.
4685 * Moved the WHOIS printing to the application. The client libary
4686 does not print out the WHOIS information anymore, the application
4687 must do it. Renamed silc_client_command_reply_whois_print to
4688 the silc_client_command_reply_whois_save.
4690 The client's idle time is also sent to the application now, and
4691 the idle is shown on screen.
4693 * Added silc_client_command_reply_identify_save to save the
4694 received IDENTIFY entries.
4696 * Do not check for channel private keys in message sending and
4697 reception if the channel does not have the PRIVKEY mode set.
4698 Affected file lib/silclient/client_channel.c.
4700 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4703 just surfaced after chaning the JOIN procedure.
4705 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4707 * Added silc_client_get_clients_by_list to get client entries
4708 from Client ID list, that is returned for example by JOIN
4709 and USERS command replies. The application should use this
4710 function for example when JOIN command reply is received to
4711 resolve the clients already on the channel (library does not
4712 do that anymore as USERS command reply is not used in the JOIN
4713 procedure anymore). Affected files lib/silcclient/silcapi.h and
4714 lib/silcclient/idlist.c.
4716 * JOIN command reply and USERS command reply returns now SilcBuffer
4717 pointers instead of unsigned char pointers when returning
4718 the client list and mode list.
4720 * Added <Client ID> argument to the JOIN command reply, mainly
4721 for the server to identify for which client the command was
4722 originally sent. Updated protocol specs accordingly.
4724 * Added SilcDlist private_key pointer to the SilcChannelEntry
4725 in the client to support the channel private keys. Affected
4726 file is lib/silcclient/idlist.h.
4728 * Added SilcChannelPrivateKey argument to the function
4729 silc_client_send_channel_message so that application can choose
4730 to use specific private ke if it wants to. If it is not provided,
4731 the normal channel key is used, unless private keys are set.
4732 In this case the first (key that was added first) is used
4733 as the encryption key.
4735 * Implemented the support for channel private key handling.
4736 Implemented the following functions:
4738 silc_client_add_channel_private_key,
4739 silc_client_del_channel_private_keys,
4740 silc_client_del_channel_private_key,
4741 silc_client_list_channel_private_keys and
4742 silc_client_free_channel_private_keys
4744 Affected file lib/silcclient/client_channel.c.
4746 * Added the support for the private keys in the channel message
4747 sending and encryption and in the message reception and
4748 decryption. Affected funtions are
4749 silc_client_send_channel_message and silc_client_channel_message.
4751 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4753 * Added SKE's key verify callback to the client library's
4754 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4756 * Removed the statement that server (or router) must send USERS
4757 command reply when joining to the channel so that the client
4758 knows who are on the channel. Instead, the client list and
4759 client's mode list is now sent in the JOIN command reply to the
4760 client who joined channel. This is better solution.
4762 * Added function silc_server_get_users_on_channel and function
4763 silc_server_save_users_on_channel to the silcd/server.[ch].
4765 * Removed function silc_server_command_send_users from the
4768 * Do not show topic on the client library anymore. The topic is
4769 sent in the command reply notify to the application and the
4770 application must show the topic now.
4772 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4774 * Added client searching by nickname hash into the IDENTIFY and
4775 WHOIS commands in the server as they were clearly missing from
4776 them. Affected file is silcd/command.c.
4778 * Fixed a bug in private message receiving in the client library.
4779 The remote ID was freed and it wasn't supposed, now it is
4782 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4784 * Minor fix to the channel payload; allocate the data area, as it
4785 needs to be of specific length.
4787 * If the key agreement port is zero then the operating
4788 system will define the bound port. Affected files are
4789 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4791 * Added new function silc_channel_payload_decrypt into the file
4792 lib/silccore/silcchannel.[ch].
4794 * Moved the channel message etc, check from silc_packet_decrypt
4795 to applications. The library calls now a generic
4796 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4797 when the packet is either normal or special. This was done to
4798 allow more wide range of checking that was not allowed when
4799 the code was in library. Now applications can do virtually any
4800 checks to the packet and return to the library the decision how
4801 the packet should be processed. Affected files are
4802 lib/silccore/silcpacket.[ch].
4804 Added silc_server_packet_decrypt_check to the server and
4805 silc_client_packet_decrypt_check to the client library.
4807 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4808 to send with specified source and destination information.
4810 * Channel message delivery between routers was broken after the
4811 channel key distribution was fixed earlier. The channel key
4812 was used be to distributed to other routers as well which is not
4813 allowed by the protocol. Now this is fixed and channel keys
4814 really are cell specific and the channel message delivery between
4815 routers comply with the protocol specification.
4817 * Fixed various commands in server to check also the global list
4818 for the channel entry and not just the local list. The affected
4819 file silcd/command.c.
4821 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4823 * Added assert()s to buffer formatting and unformatting routines
4824 to assert (if --enable-debug) when error occurs. Affected
4825 file: lib/silcutil/silcbuffmt.c.
4827 * Changed to auto-reconnect to check whether the remote host is
4828 router and register the re-connect timeout if it is. It used
4829 to check that whether we are normal server, but router must do
4830 auto-reconnect with another router as well. Affected file
4833 * Removed the [<key len>] option from CMODE command as the cipher
4834 name decides the key length, nowadays. See the defined ciphers
4835 from the protocol specification.
4837 * Added [<hmac>] option to the CMODE command to define the HMAC
4838 for the channel. Added SILC_CMODE_HMAC channel mode.
4840 * Added [<hmac>] option for the JOIN command so that user can
4841 select which HMAC is used to compute the MACs of the channel
4844 * Added Hmac field to the Channel Message Payload. The integrity
4845 of plaintext channel messages are now protected by computing
4846 MAC of the message and attaching the MAC to the payload. The
4847 MAC is encrypted. Now, it is clear that this causes some
4848 overhead to the size of the packet but rationale for this is that
4849 now the receiver can verify whether the channel message decrypted
4850 correctly and also when private keys are set for the channel the
4851 receiver can decrypt the packet with several keys and check from
4852 the MAC which key decrypted the message correctly.
4854 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4855 lib/silccrypt/silccipher.[ch].
4857 * Added silc_hash_len to return the digest length into the
4858 lib/silcrypt/silchash.[ch].
4860 * Rewrote parts of Silc Channel Payload interface in the
4861 lib/silccore/silcchannel.[ch]. The encode function now also
4862 encrypts the packet and parse function decrypts it.
4864 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4866 * Fixed a minor formatting bug in the SKE's key material processing.
4867 It actually might have processed the keys wrong way resulting
4870 * Redefined the mandatory HMAC algorithms and added new algorithms.
4871 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4872 and hmac-md5 truncated to 96 bits. The mandatory is now
4873 hmac-sha1-96. Rest are optional (including the one that used
4874 to be mandatory). Rationale for this is that the truncated HMAC
4875 length is sufficient from security point of view and can actually
4876 make the attack against the HMAC harder. Also, the truncated
4877 HMAC causes less overhead to the packets. See the RFC2104 for
4880 * Added new [hmac] configuration section. The SKE used to use
4881 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4882 is of course wrong. The official names that must be proposed in
4883 the SKE are the ones defined in the protocol specification
4884 (hmac-sha1-96 for example). The user can configure any hmac
4885 using any hash function configured in the [hash] section. At
4886 least, the mandatory must be configured.
4888 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4890 * Added HMAC list to the SKE proposal list. It has now both
4891 hash algorithm list and HMAC list. This makes the protocol
4892 incompatible with previous versions. The SKE now seems to work
4893 the way it is supposed to work, for the first time actually.
4895 * Defined plain Hash algorithms to the protocol specification.
4898 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4900 * Implemented support for key agreement packets into the server.
4901 Added functions silc_server_key_agreement and
4902 silc_server_send_key_agreement. Other than these functions,
4903 server has nothing to do with this packet.
4905 * Added support for private message key packets into the server.
4906 Added functions silc_server_private_message_key and
4907 silc_server_send_private_message_key.
4911 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4912 called in the protocol's final callback instead in the END
4913 protocol state. This makes a little more sense and in the same
4914 time in client we can use the same protocol routines for normal
4915 key exchange and to key agreement packet handling as well.
4917 * Added to both client's and server's KE protocol context the
4918 SilcSKEKeyMaterial pointer to save the key material. We will
4919 bring the key material to the protocol's final callback by doing
4920 this. The final callback must free the key material.
4922 * Added SKE's packet_send callback into client's KE protocol
4923 context so that the caller can choose what packet sending function
4924 is used. This way we can use different packet sending when
4925 doing normal SKE when doing key agreement packet handling (in
4926 the key agreement packet handling we do not want to encrypt
4929 * Implemented the responder side of the key agreement routines
4930 in the client. The client can now bind to specified port and
4931 accept incoming key negotiation. The key material is passed
4932 to the application after the protocol is over.
4934 * Implemented the processing of incoming Key Agreement packet
4935 in the client. Added function silc_client_key_agreement to
4938 * Implemented the intiator side of the key agreement routines
4939 in the client. The client can now initiate key agreement with
4940 another remote client. The key material is passed to the
4941 application after the protocol is over.
4943 * Created client_keyagr.c to include all the key agreement
4946 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4947 SILC_TASK_CALLBACK except that it is not static.
4949 * Created client_notify.c and moved the Notify packet handling
4950 from the client.[ch] into that file.
4952 * Created client_prvmsg.c and moved all private message and
4953 private message key routines from the client.[ch] into that file.
4955 * Create client_channel.c and moved all channel message and
4956 channel private key routines from the client.[ch] into that file.
4958 * Changed silc_client_get_client_by_id_resolve to resolve with
4959 WHOIS command instead of IDENTIFY command, in the file
4960 lib/silclient/idlist.c.
4962 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4964 * Implemented the SKE's responder side to the Client library.
4966 * When FAILURE is received to the protocol do not trust it
4967 blindly. Register a timeout to wait whether the remote closes
4968 the connection as it should do it, only after that process the
4969 actual failure. This was changed to both client and server.
4971 * Added client_internal.h to include some of the structures
4972 there instead of client.h in lib/silcclient/.
4974 * Added function silc_task_unregister_by_callback to unregister
4975 timeouts by the callback function.
4977 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4979 * Some "Incomplete WHOIS info" errors has been appearing on the
4980 log files. Took away the entry->userinfo check from WHOIS
4981 reply sending. The entry->userinfo is now " " if client did not
4982 provide one. I thought this was fixed earlier but something
4983 is wrong still. Let's see if the error still appears.
4985 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4987 * Fixed a minor bug in the login when the channel key is
4988 re-generated in the server. It used to generate the key in
4989 wrong order and thus caused problems in the channel traffic.
4991 * Fixed a minor bug in channel key distsribution after
4992 KICK command. The key was not sent to the router even though
4995 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * Added silc_ske_process_key_material_data as generic routine
4998 to process any key material as the SILC protocol dictates. The
4999 function is used by the actual SKE library but can be used by
5000 applications as well. This relates to the private message keys
5001 and the channel private keys since they must be processed the
5002 same way the normal SILC session keys. The protocol dictates
5003 this. Affected files: lib/silcske/silcske.[ch].
5005 Added also silc_ske_free_key_material to free the
5006 SilcSKEKeyMaterial structure.
5008 * Defined silc_cipher_set_key function to set the key for
5009 cipher without using the object's method function. The affected
5010 files: lib/silccrypt/silccipher.[ch].
5012 * Implemented silc silc_client_add_private_message_key,
5013 silc_client_add_private_message_key_ske,
5014 silc_client_del_private_message_key,
5015 silc_client_list_private_message_keys and
5016 silc_client_free_private_message_keys functions in the
5019 Added functions silc_client_send_private_message_key to send
5020 the Private Message Key payload and silc_client_private_message_key
5021 to handle incoming Private Message Key payload.
5023 * Added Cipher field to the Private Message Key payload to set
5024 the cipher to be used. If ignored, the default cipher defined
5025 in the SILC protocol (aes-256-cbc) is used.
5027 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5029 * Removed lib/silcclient/ops.h file.
5031 Redefined parts of the SILC Client Library API. Created new
5032 file silcapi.h that deprecates the ops.h file and defines the
5033 published Client Library API. Defined also private message key
5034 API and channel private key API into the file.
5036 This is the file that the application must include from the
5037 SILC Client Library. Other files need not be included by
5038 the application anymore.
5040 * Added new key_agreement client operation callback and also
5041 defined the Key Agreement library API for the application.
5043 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5045 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5046 is used by clients to request key negotiation between another
5047 client in the SILC network. If the negotiation is started it
5048 is performed using the SKE protocol. The result of the
5049 negotiation, the secret key material, can be used for example
5050 as private message key.
5052 Implemented the Key Agreement payload into the files
5053 lib/silccore/silauth.[ch].
5055 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Redefined ciphers for the SILC protocol. Added some new ciphers
5058 and defined the key lengths for the algorithms. Changed the
5059 code accordingly. The default key length is now 256 bits.
5061 * Fixed SKE key distribution function silc_ske_process_key_material
5062 when the key length is more than 128 bits. The default key
5063 length in SILC is now 256 bits.
5065 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5066 to indicate unsupported algorithm.
5068 * Renamed rijndael.c to aes.c and all functions as well.
5070 * Fixed a long standing channel key setting bug in client library.
5071 Weird that it has never surfaced before.
5073 * Fixed bug in channel deletion. If the entire channel is removed
5074 then it must also delete the references of the channel entry
5075 from the client's channel list as the client's channel entry and
5076 the channel's client entry share same memory.
5078 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5080 * Implemented CONNECT and SHUTDOWN commands in the client.
5082 * Implemented CLOSE command to the client.
5084 * Added the function silc_idlist_find_server_by_name into the
5085 files silcd/idlist.[ch].
5087 Added the function silc_idlist_find_server_by_conn into the
5088 files silcd/idlist.[ch].
5090 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5092 * DIE command was renamed to SHUTDOWN. Updated the both code
5095 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5096 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5098 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5101 * Added function silc_server_create_connection function to create
5102 connection to remote router. My server implementation actually
5103 does not allow router to connect to normal server (it expects
5104 that normal server always initiates the connection to the router)
5105 so the CONNECT command is only good for connecting to another
5108 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5110 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5111 or some other client was kicked from the channel.
5113 Implemented the handling of the notify type to both client
5116 Implemented silc_server_send_notify_kicked to send the KICKED
5117 notify. It is used to send it to the server's primary router.
5119 * Implemented the KICK command into server and client.
5121 * Added `query' argument to the silc_idlist_get_client function
5122 to indicate whether to query the client from server or not if
5125 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5126 to indicate that the client is not channel founder.
5130 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5132 * Removed the rng context from SilcPacketContext structure and
5133 changed that the packet routine uses the Global RNG API.
5135 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * Added support for quit message that client can "leave" on the
5138 channel when it quits the SILC. It is ditributed inside the
5139 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5141 Added silc_server_free_client_data that will take the
5142 signoff message as argument.
5144 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5146 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5148 * Updated parts of the protocol specification to keep it up
5151 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5153 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5154 payloads in one packet.
5156 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5157 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5158 use now the new List flag.
5160 * Also deprecated the following packet types: REPLACE_ID,
5161 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5163 * Added list support for Notify packet in server.
5165 * Added silc_server_send_notify_channel_change to send the
5166 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5167 the silc_server_send_replace_id.
5169 * Added silc_server_send_notify_nick_change to send the
5170 NICK_CHANGE notify type. Deprecates the function
5171 silc_server_send_replace_id.
5173 * Added silc_server_send_notify_join to send the JOIN notify type.
5174 Deprecates the function silc_server_send_new_channel_user.
5176 * Added silc_server_send_notify_leave to send LEAVE notify type.
5177 Deprecates the function silc_server_send_remove_channel_user.
5179 * Added silc_server_send_notify_cmode and
5180 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5181 types. Deprecates the silc_server_send_set_mode function.
5183 * Added SERVER_SIGNOFF notify type to indicate that server has
5184 quit. This means that all clients on the channel from that
5185 server will drop. This can be also used when netsplit happens.
5187 Deprecated REMOVE_ID packet type since it is not needed anymore
5190 Added silc_server_send_notify_server_signoff to send the
5191 SERVER_SIGNOFF notify type. Deprecates the function
5192 silc_server_send_remove_id.
5194 Added also silc_server_send_notify_signoff to send the
5195 SIGNOFF notify type.
5197 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5198 SILC protocol from this day on. Changed the protocol
5199 specification as well.
5201 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5202 notify type. It is used between routers to notify about
5203 topic changes on a channel.
5205 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5208 * Partly updated the protocol specification to comply with the
5209 changes now made. It is still though a bit outdated.
5211 * The JOIN notify type now takes one extra argument <Channel ID>.
5212 The packet used to be destined to the channel but now the
5213 JOIN type may be sent as list thus it is impossible to
5214 destine it to any specific channel. By adding this argument
5215 it is again possible.
5217 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5219 * Added CREDITS file. The CHANGES and CREDITS file will appear
5220 in the distribution as well.
5222 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5224 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5225 types in the server's silcd/packet_receive.c.
5227 * Implemented CMODE and CUMODE to work in router environment.
5229 * Fixed minor encoding and decoding buglet from the
5230 lib/silccore/silcmode.c.
5232 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5235 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5237 * Changed all SilcConfigServer* and silc_config_server* to
5238 SilcServerConfig* and silc_server_config*, respectively.
5241 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Associated the ID (client or server ID) to the Authentication
5244 Payload to avoid any possibility of forging. Updated the
5245 protocol specification and the code accordingly.
5247 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * The RSA key length is now save to the RsaKey context in the
5250 key generation process in lib/silccrypt/rsa.c. The key length
5251 is now used to figure out the maximum size of the block allowed
5252 to be encrypted/signed.
5254 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5255 is equivalent to the silc_mp_mp2bin but does not allocate any
5258 * Changed silc_mp_mp2bin API to take length argument. If it is
5259 non-zero then the buffer is allocated that large. If zero, then
5260 the size is approximated using silc_mp_sizeinbase, which however
5263 * Created Global RNG API which is global RNG that application can
5264 initialize. After initializing, any routine anywhere in the
5265 code (including library) can use RNG without allocating a new
5266 RNG object. This was done to allow this sort of use of the
5267 RNG in code that has no chance to allocate RNG object. All
5268 applications currently allocate this and many routines in the
5269 library use this. Affected file lib/silccrypt/silcrng.[ch].
5271 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5272 it to use the Global RNG API.
5274 * Defined Authentication Payload into protocol specification that
5275 is used during SILC session to authenticate entities. It is
5276 used for example by client to authenticate itself to the server
5277 to obtain server operator privileges.
5279 Implemented this payload into the lib/silccore/silcauth.[ch].
5280 Implemented also routines for public key based authentication
5281 as the new protocol specification dictates.
5283 Moved definitions of different authentication methods from
5284 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5286 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5287 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5288 silc_pkcs_verify_with_hash functions into the file
5289 lib/silccrypt/silcpkcs.[ch].
5291 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * The client entry's userinfo pointer must be always valid.
5294 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5295 will fail since it requires the userinfo. Now, the userinfo
5296 is allocated as "" if actual userinfo does not exist. Actually,
5297 it must exist and it is totally Ok to drop client connections
5298 that does not announce the userinfo. However, we will make
5299 this workaround for now.
5301 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5302 to return the remote port by socket.
5304 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5306 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5307 SILC_SERVER_PENDING_EXEC and added an new macro
5308 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5309 data or when error occurs while processing the pending command.
5311 Added new argument `destructor' into silc_server_command_pending
5312 and to the SilcServerCommandPending object. This destructor is
5313 now called after calling the pending callback or if error occurs
5314 immediately. If error occurs the actual pending callback won't
5315 be called at all - only the destructor. The destructor may be
5316 NULL if destructor is not needed.
5318 All this applies for client library code as well. Similar
5319 changes were made there as well for the pending commands.
5321 In the client, the application must now allocate the
5322 SilcClientCommandContext with the silc_client_command_alloc
5325 * Added reference counter to the SilcServerCommandContext. Added
5326 function silc_server_command_alloc and silc_server_command_dup
5329 Same type of functions added to the client library for the same
5332 * Removed the cmd_ident from IDListData away since it is now
5333 global for all connections. It is the command identifier used
5334 in command sending and with pending commands. The affected file
5337 * Added reference counter to the SilcSocketConnection objecet to
5338 indicate the usage count of the object. The object won't be
5339 freed untill the reference counter hits zero. Currently only
5340 server uses this, and client ignores it. The client must be
5341 set to use this too later. The affected files are
5342 lib/silccore/silcsockconn.[ch]. Added also the function
5343 silc_socket_dup to increase the reference counter.
5345 This was mainly added because it is possible that the socket
5346 is removed underneath of pending command or other async
5347 operation. Now it won't be free'd and proper DISCONNECTING
5348 flags, etc. can be set to avoid sending data to connection that
5349 is not valid anymore.
5351 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5352 the connection. After that it sets SILC_SET_DISCONNECTED.
5353 It is, however, possible that the socket data is not still freed.
5354 The silc_server_packet_process now checks that data is not
5355 read or written to connection that is DISCONNECTED. The socket
5356 get's freed when the reference counter hits zero.
5358 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5360 * Changed the client operation API: channel_message operation's
5361 `sender' is now the client entry of the sender, not the nickname
5362 and the `channel' is the channel entry, not the channel name.
5364 In the private_message operation the `sender' is now also the
5365 client entry of the sender not the nickname.
5367 Affected file is lib/silcclient/ops.h and all applications
5368 using the client operations.
5370 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5372 * Moved the calling of ops->connect() from connect_to_server_final
5373 into receive_new_id functin since that is the point when the
5374 client is actually allowed to send traffic to network. The
5375 affected file is lib/silcclient/client.c.
5377 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5379 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5380 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5381 (if needs broadcasting) instead of broadcasting the packets one
5382 by one which would make a burst in the network traffic.
5384 * Added `broadcast' argument to the functions in silcd/server.[ch]
5385 silc_server_create_new_channel[_with_id] to indicate whether
5386 to send New Channel packet to primary router.
5388 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Added new function into the silcd/server.[ch] files:
5391 silc_server_create_new_channel_with_id to create new channel with
5392 already existing Channel ID.
5394 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5395 lib/silccore/silcpacket.h. This packet is used t send list of
5396 Set Mode payloads inside one packet. Server uses this to set
5397 the modes for the channels and clients on those channels, that it
5398 announced to the router when it connected to it. The protocol
5399 specification has been updated accordingly.
5401 * The silc_server_new_channel did not handle the packet coming
5402 from normal server as it normally does not send that. However,
5403 when it announces its channels it does send it. Implemented
5404 the support for that.
5406 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5407 into the file lib/silccore/id.h.
5409 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5411 * Fixed memory leaks in the functions silc_idlist_del_client,
5412 silc_idlist_del_channel and silc_idlist_del_server in the file
5413 silcd/idlist.c. All of those leaked like a sieve.
5415 * Fixed some small memory leaks in the client's function
5416 silc_client_notify_by_server.
5418 * Added functions into silcd/server.c: silc_server_announce_clients,
5419 silc_server_announce_channels and silc_server_announce_server.
5420 These functions are used by normal and router server to announce
5421 to its primary router about clients, channels and servers (when
5422 router) that we own. This is done after we've connected to the
5425 These functions effectively implements the following packet types:
5426 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5427 and SILC_PACKET_NEW_ID_LIST.
5429 * Added new functions into the silcd/packet_receive.[ch]:
5430 silc_server_new_id_list, silc_server_new_channel_list and
5431 silc_server_new_channel_user_list to handle the incoming
5432 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5434 * Added support of changing Channel ID in the function
5435 silc_server_replace_id. If the server that announces a channel
5436 to the router already exists in the router (with same name but
5437 with different Channel ID), router is responsible to send
5438 Replace ID packet to the server and force the server to change
5439 the Channel ID to the one router has.
5441 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5442 client that the Channel ID has been changed by the router. The
5443 normal server sends this to the client. Client must start using
5444 the new Channel ID as the channel's ID.
5446 Implemented handling of this new type into lib/silcclient/client.c
5447 into the function silc_client_notify_by_server.
5449 * Added new function silc_idlist_replace_channel_id into the files
5450 silcd/idlist.[ch] to replace the Channel ID.
5452 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5454 * Call silc_server_command_identify_check always when processing
5455 the IDENTIFY command in silcd/command.c
5457 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5459 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5460 send keepalive packets. The packet can be sent by clients,
5461 servers and routers.
5463 Added function silc_socket_set_heartbeat into the file
5464 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5465 If not set, the heartbeat is not performed. The actual
5466 heartbeat is implemented in the low level socket connection
5467 library. However, application is responsible of actually
5470 Added silc_server_send_heartbeat to send the actual heartbeat
5471 packet into silcd/packet_send.[ch]. Server now performs
5472 keepalive with all connections.
5474 * Added silc_task_get_first function into lib/silcutil/silctask.c
5475 to return the timeout task with shortest timeout. There was a bug
5476 in task unregistration that caused problems. TODO has been
5477 updated to include that task system must be rewritten.
5479 * The client library will now resolve the client information when
5480 receiving JOIN notify from server for client that we know but
5481 have incomplete information.
5483 * Rewrote parts of silc_server_remove_from_channels and
5484 silc_server_remove_from_one_channel as they did not remove the
5485 channel in some circumstances even though they should've.
5487 * Encryption problem encountered in server:
5489 The LEAVE command used to send the Channel Key packet to the
5490 router immediately after generating it. However, the code
5491 had earlier sent Remove Channel user packet but not immediately,
5492 ie. it was put to queue. The order of packets in the router
5493 was that Channel Key packet was first and Remove Channel User
5494 packet was second, even though they were encrypted in the
5495 reverse order. For this reason, MAC check failed. Now, this
5496 is fixed by not sending the Channel Key packet immediately but
5497 putting it to queue. However, this is more fundamental problem:
5498 packets that are in queue should actually not be encrypted
5499 because packets that are sent immediately gets encrypted
5500 actually with wrong IV (and thus MAC check fails). So, packets
5501 that are in queue should be encrypted when they are sent to
5502 the wire and not when they put to the queue.
5504 However, the problem is that the current system has not been
5505 designed to work that way. Instead, the packet is encrypted
5506 as soon as possible and left to the queue. The queue is then
5507 just purged into wire. There won't be any fixes for this
5508 any time soon. So, the current semantic for packet sending
5511 o If you send packet to remote host and do not force the send
5512 (the packet will be in queue) then all subsequent packets to the
5513 same remote host must also be put to the queue. Only after the
5514 queue has been purged is it safe again to force the packet
5517 o If you send all packets immediately then it safe to send
5518 any of subsequent packets through the queue, however, after
5519 the first packet is put to queue then any subsequent packets
5520 must also be put to the queue.
5522 Follow these rules and everything works fine.
5524 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5526 * Added new function silc_server_remove_clients_by_server to
5527 remove all client entries from ID list when the server connection
5528 is lost. In this case it is also important to invalidate all
5529 client entires as they hold the invalid server entry. This
5530 fixes fatal bug when server has lost connection and will reconnect
5533 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Made some sanity checks to silc_server_daemonise like to check
5536 whether the requested user and group actually exists.
5538 * Added sanity check to SKE's silc_ske_responder_finish to check
5539 that the public and private key actually is valid.
5541 * Invalidate the client's nickname when receiving Replace ID
5542 packet and the Client ID is being replaced. This means that the
5543 server will query the nickname if someone needs it (client)
5546 * Sort the ID Cache in client library when the ID Cache data
5547 has changed (needs sorting).
5549 * Do not allow for SILC client to create several connections to
5550 several servers. The client does not support windows right now
5551 and generating multiple connections causes weird behaviour.
5553 Irssi-silc client does support windows and can handle several
5554 connections without problems, see: www.irssi.org and SILC plugin.
5556 * Fixed some places where client was added to the IDList. The
5557 rule of thumb is following (in order to get everything right):
5558 If the client is directly connected local client then the
5559 `connection' argument must be set and `router' argument must be
5560 NULL to silc_idlist_add_client function. If the client is not
5561 directly connected client then the `router' argument must
5562 bet set and the `connection' argument must be NULL to the
5563 silc_idlist_add_client function.
5565 * The funtion silc_server_packet_send_local_channel actually did
5566 not check whether the client was locally connected or not. It
5567 does that now. Fixed a bug related to LEAVE command.
5569 * Fixed Remove Channel User payload parsing bug in server's
5570 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5572 * The server's silc_server_save_channel_key now checks also the
5573 global ID list for the channel as it might not be in the local
5574 list. Fixed a bug related to LEAVE command.
5576 * Is this the end of the [<unknown>] buglet that has been lurking
5577 around for a long time? A little for loop fix in server's
5578 silc_server_command_whois_parse that is used by both IDENTIFY
5579 and WHOIS command. At least, this was a clear bug and a cause
5580 of one type of [<unknown>] buglet.
5582 * WHOIS and IDENTIFY commands call the function
5583 silc_server_command_[whois/identify]_check function even if
5584 we are not router server.
5586 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5588 * Added --with-gmp configuration option. If set the GMP
5589 is always compiled in the SILC source tree. If not set then
5590 it is checked whether the system has the GMP3 installed. If
5591 it has then the GMP won't be compiled (the system's headers
5592 and library is used), if it doesn't have it then the GMP is
5593 compiled in the SILC source tree.
5595 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5597 * Changed RSA private exponent generation to what PKCS #1
5598 suggests. We try to find the smallest possible d by doing
5599 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5600 not security fix but optimization.
5602 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5604 * Added new config entry [Identity] to fork the server and run
5605 it as specific user and group. A patch from Bostik.
5607 * Imported Dotconf configuration library into lib/dotconf.
5608 This will be used to create the SILC configuration files later.
5609 It will appear in the distsribution after this commit.
5611 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5613 * A big code auditing weekend happening. Auditing code for
5614 obvious mistakes, bugs and errors. Also, removing any code
5617 Removed files for being obsolete:
5619 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5620 inline in the file lib/silcutil/silcbuffer.h)
5622 o lib/silcutil/silcbufutil.c (the header has inline versions)
5624 Changed code to fix possible error conditions:
5626 o The buffer formatting routines now check that the destination
5627 buffer really has enough space to add the data. This applies for
5628 both buffer formatting and unformatting
5629 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5630 unformatting was changed to accomodate following rules:
5631 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5632 sent to the function while XXX_*STRING will not allocate or copy
5633 the data into the buffer. Instead it sets the pointer from the
5634 buffer into the pointer sent as argument (XXX_*STRING used to
5635 require that the pointer must be allocated already). This change
5636 makes this whole thing a bit more consistent and more optimized
5637 (note that the data returned in the unformatting with XXX_*STRING
5638 must not be freed now). The routines return now -1 on error.
5640 o Tried to find all code that use buffer_format and buffer_unformat
5641 and added return value checking to prevent formatting and
5642 especially unformatting errors and possible subsequent fatal
5645 o Changed ske->x and ske->KEY to mallocated pointers in
5646 lib/silcske/silcske.h. Fixed possible data and memory leak.
5648 o Added return value checking to all *_parse* functions. Fixed
5649 many memory leaks as well.
5651 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5652 so that buffer overflows would not happen. All code now also
5653 checks the return value as it can fail.
5655 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5657 * Added reconnection support to server if the normal server looses
5658 its connection to the router (for example if router is rebooted).
5659 The server performs normal reconnection strategy implemented
5660 to the server. Affected file silcd/server.c.
5662 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5664 * Added new packet type SILC_PACKET_SET_MODE that is used to
5665 distribute the information about changed modes (for clients,
5666 channels and clients channel modes) to all routers in the
5667 network. Updated the protocol specification accordingly.
5669 Added functions into silcd/packet_send.c and
5670 silcd/packet_receive.c: silc_server_send_set_mode,
5671 silc_server_set_mode.
5673 Added new files silcmode.[ch] into lib/silccore that implements
5674 the encoding and decoding of Set Mode Payload. Added new type
5675 SilcSetModePayload. Moved the definitions of different modes
5676 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5678 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5680 * Oops, a little mistake in server's connection authentication
5681 protocol. The protocol is not ended with FAILURE but with
5682 SUCCESS if the authentication is Ok. :) Affected file is
5685 * Implemented NICK_CHANGE notify handling in server in the file
5686 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5687 the local clients on the channel. After the changing nickname
5688 in router environment snhould work and the [<unknown>] nickname
5689 should appear no more.
5691 The silc_server_replace_id function that receives the Replace ID
5692 payload now sends the NICK_CHANGE notify type also in the file
5693 silcd/packet_receive.c
5695 * Changed WHOIS and IDENTIFY command to support the maximum amount
5696 of arguments defined in protocol specs (3328 arguments). This
5697 fixed a bug that caused problems when there were more than three
5700 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5702 * Added extra parameter, command identifier, to the
5703 silc_client_send_command so that explicit command identifier
5706 Changed that ID list routines uses specific command identifier
5707 when sending WHOIS/IDENTIFY requests to the server so that they
5708 can be identified when the reply comes back.
5710 Affected files lib/silcclient/command.[ch],
5711 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5713 * Added `sender' argument to silc_server_packet_send_to_channel
5714 to indicaet the sender who originally sent the packet to us
5715 that we are now re-sending. Ignored if NULL. Affected file
5716 silcd/packet_send.[ch].
5718 * Added some server statistics support in silcd/server_internal.h
5719 SilcServerStatistics structure and around the server code. Also
5720 send some nice statistics information when client is connecting
5723 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5725 * Fixed channel ID decoding in server's JOIN command reply in
5726 silcd/command_reply.c
5728 * Fixed braodcasting of replace ID payload to not to send it if
5729 we are standalone server in silcd/packet_receive.c.
5731 * Fixed all channel message sending routines to not to send
5732 packets to clients that has router set, since they are routed
5733 separately in the same function earlier. Affects file
5734 silcd/packet_send.c and all channel packet sending functions.
5736 * In USERS reply, res_argv[i] are not allocated, the table
5737 is allocated. Thus changed that free the table, not its
5740 * In server's whois_check and identify_check if the client is
5741 locally connected do not send any WHOIS commands - they are not
5744 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5746 * Fixed some minor bugs in client when sending WHOIS command. The
5747 arguments was in wrong order.
5749 * Removed statis function add_to_channel from server in
5750 silcd/command.c that was previously used with the joining but
5753 * Tested USERS command in router environment successfully with two
5754 routers, two servers and two clients.
5756 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5758 * Reorganized the USERS command and command reply in client library
5759 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5760 When the command is given by user we register a pending command
5761 callback that will reprocess the command after the reply has been
5762 received from the server. When reprocessing the packet we then
5763 display the information. Thus, the USERS information is displayed
5764 now in the command callback instead of in the command reply
5765 callback. The processing of the command is same as previously
5766 when server has sent the command reply in the JOINing process.
5768 * Added to USERS command in silcd/command_reply.c to join the client,
5769 we didn't use to know about, to the channel after we've created
5770 a client entry for it. Also, for clienet we did know already still
5771 check whether it is on the channel or not and add it if not.
5773 * Removed silc_server_command_join_notify as the function and its
5776 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Changed the client's pending command handling to the same as the
5779 server's pending command handling. It is also now possible to
5780 execute command reply functions from other command reply
5781 function as the function callbacks for commands and command
5782 replies are one and same. The pending commands are not static
5783 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5784 in client connection context. Thus, pending commands are server
5785 connection specific as it is convenient.
5787 Changed the function silc_client_command_pending and
5788 silc_client_command_pending_del and added new function
5789 silc_client_command_pending_check. Removed the
5790 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5793 * Added cmd_ident, current command identifier, to the client
5794 connection context in lib/silcclient/client.h to keep track on
5795 command identifiers used in command sending. Client's command reply
5796 function handling now supports the mandatory command identifiers.
5798 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5799 funtions in client to fully support pending command callbacks.
5801 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5802 as one of the arguments to the application in the command reply
5805 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5806 before first releasing SILC but came back. Now it is removed again
5807 and should come back nomore. The FORWARDED flag was used only
5808 by the JOINing procedure by forwarding the command packet to router.
5809 Now, the JOINing procedure has been changed to more generic (due
5810 to various router environment issues) and FORWARDED is not needed
5811 anymore for anything. The protocol specification is yet to be
5814 Now, removed silc_server_packet_forward from server and the flag
5815 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5817 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5819 * Renamed NAMES command to USERS command. The NAMES was named that
5820 due to historical reasons. Now it is renamed. Also, rewrote
5821 parts of the USERS command. The nickname list is not sent anymore
5822 by the server. Only Client ID and mode lists are sent in the USERS
5823 command. Changed this also to the protocol specification.
5825 The client now resolves the names and stuff after it receives
5826 the USERS list from the server when joining to the channel.
5828 * WHOIS and IDENTIFY commands has been changed to support multiple
5829 Client ID's per command. One can now search for multiple users
5830 in the network by sending only one WHOIS or IDENTIFY command.
5831 Changed the code and the protocol specifications.
5833 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5834 uses silc_server_command_whois_parse to parse the request. */
5836 * If normal server, do not parse the WHOIS and IDENTIFY requests
5837 before sending it to the router. Saves some time.
5839 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5841 * Fixed JOIN command on client library. Wrong number of arguments
5842 used to crash the client.
5844 * Added silc_server_channel_has_global function to check whether
5845 channel has global users or not.
5847 * Added silc_server_channel_has_local function to check whether channel
5848 has locally connected clients on the channel.
5850 * The silc_server_remove_from_one_channel now checks whether the
5851 channel has global users or not after given client was removed from
5852 the channel. It also checks whether the channel has local clients
5853 on the channel anymore. If it does not have then the channel entry
5854 is removed as it is not needed anymore.
5856 * The silc_server_notify now checks on JOIN notify whether the joining
5857 client is one of locally connected or global. If it is global then
5858 the channel has now global users on the channel and that is marked
5859 to the channel entry. Also, it now saves the global client to
5860 global list who is joining and JOINs it to the channel. This is
5861 for normal server, that is.
5863 Changed silc_server_send_notify_on_channel,
5864 silc_server_packet_relay_to_channel and
5865 silc_server_packet_send_to_channel check if we are normal server
5866 and client has router set (ie. global client) do not send the
5867 message to that client, as it is already routed to our router.
5869 * Implemented LEAVE notify type handling in silc_server_notify
5872 * Tested LEAVE command in router environment successfully. Tested
5873 with two routers, two servers and two clients.
5877 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5879 * Implemented SIGNOFF notify type handling in silc_server_notify
5882 * silc_server_remove_id now removes the client entry from all channels
5883 it has joined and thusly sends SIGNOFF notify type.
5885 * Rewrote the NAMES list generation in server by removing two excess
5886 loops. The lists are created now inside one loop.
5888 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5890 * silc_server_remove_channel_user checks now also global list
5891 for channel and client.
5893 * silc_server_new_channel_user checks now both local and global
5894 list for channel and client. Fixed a bug in client id decoding.
5895 Used to decode wrong buffer.
5897 * silc_server_channel_message checks now both local and global
5898 list for channel entry.
5900 * Tested channel joining (hence JOIN) in router environment
5901 successfully. Tested with two routers, two servers and two
5904 * Tested channel message sending in router environment successfully.
5906 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5908 * Added silc_server_save_channel_key into server.[ch] to save the
5909 received channel key in Channel Key payload processing. It is
5910 also used in JOIN command reply handling.
5912 Equivalent function silc_client_save_channel_key added into
5913 client.[ch] into client library.
5915 * Changed JOIN command reply to send information whether the channel
5916 was created or not (is existing already) and the channel key
5917 payload. Changed protocol specs accordingly.
5919 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5920 the request was sent by ID and not by nickname. Crashed on
5923 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5925 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5926 now correctly save the received data.
5928 * silc_server_free_sock_user_data now notifies routers in the
5929 network about entities leaving the network.
5931 At the same time implemented functions silc_server_remove_id
5932 and silc_server_send_remove_id to receive and send REMOVE_ID
5933 packets. The packet is used to notify routers in the network
5934 about leaving entities. The ID removed will become invalid in
5937 * Added function silc_idlist_del_server into server. Removes and
5938 free's server entry from ID list.
5940 * silc_server_private_message function now checks, if we are router,
5941 that the destination ID really is valid ID, naturally.
5943 * In router when NEW_ID packet is received (for new client) the
5944 hash of the Client ID is saved in the ID Cache but the
5945 client->nickname is set to NULL, instead of putting the hash
5948 IDENTIFY command now also checks that client->nickname must be
5949 valid. If it is not if will request the data from the server who
5950 owns the client. Added new function
5951 silc_server_command_identify_check.
5953 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5954 to set the command to already allocated Command Payload.
5956 * Tested private message sending in router environment with two
5957 routers, two servers and two clients. Fixed minor bugs and now
5960 * Fixed segfault from client's NAMES command. Used to crash if
5963 * Forwarded packets must not be routed even if it is not destined
5964 to the receiver. Changed server code comply with this.
5966 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5968 * Added `require_reverse_mapping' boolean value to ServerParams
5969 structure. If TRUE (not default) the server will require that
5970 the connecting host has fully qualified domain name.
5972 If the reverse mapping is not required and hostname could not be
5973 found the IP address is used as hostname.
5975 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5977 * Implemented version string checking to both client and server.
5978 The check is incomplete currently due to the abnormal version
5979 strings used in development version of SILC.
5981 * Changed all command functions in server to use the new
5984 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5986 * Changed char *data to unsigned char *data in ID Cache system to
5987 support binary data as ID Cache data. Changed code to support
5988 binary data in lib/silccore/idcache.c.
5990 * Renamed silc_server_packet_relay_command_reply to
5991 silc_server_command_reply as it is normal packet receiving
5992 function. Rewrote the function to accept command replys for
5993 servers and not only for clients.
5995 * Mark remote router always as registered server if we are connecting
5996 to it. Otherwise, commands sent by the router to us are ignored.
5998 * All ID List find routines now returns the ID Cache Entry pointer
5999 as well if requested.
6001 * WHOIS command works now in router environment, tested with two
6002 routers, two servers and two clients.
6004 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6005 in router environment (as it is almost equivalent to WHOIS) but
6006 hasn't been tested thoroughly. Added new functions:
6008 silc_server_command_identify_parse
6009 silc_server_command_identify_send_reply
6010 silc_server_command_identify_from_client
6011 silc_server_command_identify_from_server
6013 * Disabled route cache adding because adding two different ID's with
6014 same IP replaces the old cache entry thus giving wrong route.
6015 The entry->router->connection is always the fastest route anyway
6016 so route cache may not be needed. Of course, new routes maybe
6017 established after receiving the ID when the entry->router->connection
6018 might not be anymore the most optimal.
6020 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6022 * Add route cache for received ID for fast routing.
6024 * Added silc_server_packet_route to route received packet on router
6025 that is not destined to us.
6027 * Renamed silc_server_get_route to silc_server_route_get.
6029 * Added id_string and id_string_len fields into SilcServer to
6030 include encoded ServerID for fast comparing without excess
6031 encoding of the ID's.
6033 * Cleaned up WHOIS command on server side. Added following static
6036 silc_server_command_whois_parse
6037 silc_server_command_whois_check
6038 silc_server_command_whois_send_reply
6039 silc_server_command_whois_from_client
6040 silc_server_command_whois_from_server
6042 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6043 arguments in command replies. All command functions should be
6044 updated to use this macro.
6046 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6048 * Minor typo fixes on command reply handling on server.
6050 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6052 * Added silc_server_command_add_to_channel internal routine to add
6053 the client to the channel after router has created the channel and
6054 sent command reply to the server.
6056 * Added generic silc_server_send_command to send any command from
6059 * Use static buffer with ID rendering instead of duplicating data.
6061 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6063 * Fixed a channel user mode bug when joining to a channel server gave
6064 everybody channel founder rights, oops.
6066 * We mark ourselves as the router of the incoming server connection
6067 if we are router ourselves. This way we can check in some packet
6068 sending functions whether it is locally connected server. For
6069 incoming router connections we put NULL.
6071 * For router sending packets locally means now always sending the
6072 packet cell wide; to local clients and local servers. For normal
6073 server sending packet locally means sending it to only local
6076 * Fixed the JOIN command to really work in router environment. If the
6077 channel is created it is always created by the router. Router is
6078 also responsible of making the initial joining to the channel,
6079 sending JOIN notify to the sending server and distributing
6080 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6081 does not exist server doesn't do anything else but forward the
6082 command to the router which performs everything.
6084 * Added silc_server_send_channel_key function to send the Channel Key
6087 * Added silc_server_create_channel_key to create new channel key. The
6088 channel key is now re-generated everytime someone joins or leaves
6089 a channel, as protocol dictates. Note: channel->key_len is the
6092 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6094 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6095 packet_receive.[ch] to separate packet sending and receiving
6096 routines. The server.[ch] now includes everything else including
6097 actual packet processing (writing and reading data) and other
6100 Renamed silc_server_private_message_send_internal to
6101 silc_server_send_private_message. The routine is still though
6102 used only to relay private messages as server does not send
6103 private messages itself.
6105 Renamed silc_server_new_channel to silc_server_create_new_channel
6106 and added new function sicl_server_new_channel that handles the
6107 incoming New Channel packet. Added also new sending function
6108 silc_server_send_new_channel to send New Channel Payload.
6110 * Added new function silc_server_notify to process incoming notify
6111 packet to the server/router. Server may then relay the notify
6112 to clients if needed.
6114 * Added new function silc_server_new_channel_user to process incoming
6115 New Channel User packet. Router will redistribute the packet and
6116 send JOIN notify to its local clients and locally connected servers
6117 if needed. Normal server will send JOIN notify to its local client
6118 on same channel when received this packet. Added also corresponding
6119 sending function silc_server_send_new_channel_user to sent the
6122 * Added boolean route argument to send_notif_to_channel and
6123 packet_send_to_channel functions to attempt to route the packet
6124 if it is TRUE and send only locally if it is FALSE.
6126 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6128 * silc_server_replace_id now broadcasts the received replace ID
6129 packet if it is not broadcast packet already. The router must
6130 broadcast to inform other routers about changed ID.
6132 * Added backpointer to server's router into SilcServer context in
6133 silcd/server_internal.h.
6135 * Fixed silc_server_packet_broadcast to send correct broadcast
6138 * The channel key is now distributed to the local client as soon
6139 as it is received from the router (in router environment) so that
6140 no other packet may be sent for the channel until client has
6143 * silc_server_remove_channel_user now broadcasts the received
6144 Remove Channel User packet if it is not broadcast packet already.
6145 The router must broadcast to inform other routers about removed
6148 * Added users field into SilcPacketContext that is a reference count
6149 of the context. One can increase the reference count by calling
6150 silc_packet_context_dup which is now changed to just increase the
6151 reference count instead of duplicating the data. The reference
6152 count is decresed by calling silc_packet_context_free that will
6153 free the data after the reference count hits zero.
6155 For now on the packet context and everything allocated into it
6156 (including the raw packet from network) must be freed by calling
6157 the new silc_packet_context_free function. Added also new function
6158 silc_packet_context_alloc that must be used now to allocate the
6159 context. This also means that if a routine is asynchronous from
6160 silc_[client/server]_packet_parse_type the packet context must
6161 be duplicated by calling silc_packet_context_dup. Otherwise it
6162 gets free'd after silc_[client/server]_packet_parse_type returns.
6163 Also, one must remember that if packet is duplicated then its
6164 reference count must be decresed by calling the free function as
6165 many times as it was duplicated.
6167 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6168 from both client and server.
6170 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6172 * Made joining to a channel working in router environment.
6174 * Cleaned up JOIN command on server side and create function
6175 silc_server_command_join_channel internal routine to make the
6178 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6180 * Changed silc_command_pending list to SilcDList. Also, added
6181 `ident' field to SilcServerCommandPending structure to identify
6182 the reply and to call correct callback.
6184 Added silc_server_command_pending_check function to replace the
6185 corresnponding macro. The silc_command_pending list is not
6188 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6189 to set identifier to previously allocated Command Payload. It
6190 is used to set identifier for command when resending Command
6193 * Added silc_command_payload_encode_payload to encode Command
6194 Payload buffer from SilcCommandPayload structure.
6196 * Added silc_argument_payload_encode_payload to encode Argument
6197 payload buffer from SilcArgumentPayload structure.
6199 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6201 * Changed WHOIS command to support router connection on server side.
6202 The whois request is always sent to router unless the server is
6203 standalone server. After server has received the reply from the
6204 router will it send the reply to the client.
6206 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6207 broadcast received broadcast packet. The function is used only
6208 by router. The broadcast packet is always sent to the router's
6211 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6212 render given ID to printable string, for log files for example.
6214 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6216 * Made basic router to router connections working. At least they
6217 can now connect to each other but nothing really works the way
6218 they are supposed - yet.
6220 * Added new initiator token to RouterConnection configuration
6221 file in silcd/serverconfig.[ch]. It is used to tell whether we
6222 are the initiator to the remote router or whether we'll expect
6223 the other end to connect.
6225 * Moved registering of listener task to silc_server_init, hence
6226 the server starts listenning as soon as it is run, even if it
6227 does not have connections to other routers. Let's see how well
6230 * Changed default connection retry timeouts for more suitable in
6233 * Removed cipher and such arguments from silc_idlist_add_client
6234 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6235 Added new function silc_idlist_add_data to add the keys and stuff
6238 * Added SilcIDListData structure and added it to SilcClientEntry
6239 and SilcServerEntry as their first field in the structure. This
6240 way we can explicitly cast the ID entries to the SilcIDListData
6241 structure and get common data for the entries. In past, we had
6242 to first check what type of connection it is and then cast it to
6243 correct ID entry type. Now, we can directly cast the opaque
6244 pointer to the SilcIDListData (no matter what ID entry it actually
6245 is) and get the data needed.
6247 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6249 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6250 in some circumstances even if threre were timeout tasks, though not
6251 IO tasks, but tasks anyway. Now fixed.
6253 * Defined SilcServerConnection structure to hold connection specific
6254 stuff about directly connected servers and routers. The definition
6255 is currently in silcd/server_internal.h. I thought about having
6256 a bit more important role fro this struct but for now it is used
6257 only when connecting to other server (or router actually).
6259 * Added connecting retry support in server when connecting to
6260 router(s). The retry feature implement exponential backoff
6261 algorithm. Also, added SilcServerParams structure to hold default
6262 parameters for server. For now, it include these retry settings
6263 and are hard coded. After server is moded to be as Silc Server
6264 Library this structure will be more important.
6266 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6268 * Changed client librarys channel->clients table to SilcList and
6269 changed code accordingly.
6271 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6273 * Changed client's channel table to SilcList and changed code
6274 accordingly. Also changed SilcChannelClientEntry to include back-
6275 pointer to the channel so that client entry can use that structure
6276 as list as well and we have fast cross-reference to the channel.
6277 This change dramatically decreased the complexity of channel
6278 handling with client entry and vice versa (removed one extra
6279 loop when searching for channel entry from many functions).
6281 * Changed server->sim from table to SilcDList and changed code
6284 * NAMES command can now be used from user interface. It will show
6285 the user list on the channel, neatly.
6287 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6288 Code now saves realname of the user if it becomes available.
6290 * Renamed configure.in to configure.in.pre and made ./prepare
6291 script to automatically add correct version string to
6292 configure.in which it creates from configure.in.pre.
6294 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6296 * NAMES command reply now shows users mode with the nickname when
6299 * Moved silc_client_ch[u]mode[_char] functions from
6300 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6301 place sucks, they are utility functions and should be in some
6304 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6306 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6309 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6313 * Added TRQ (efficient deque and list library) into lib/trq. This is
6314 a very good list library that is currently used in the SILC. Defined
6315 SilcList API over the library because I didn't like the API very
6316 much. See lib/trq/silclist.h for the API and examples of how to
6317 use the API. Fixed various places in the code to use the new
6318 SilcList API. The SilcList is meant for lists that has a structure
6319 already defined as a list. It is not suitable to add just some
6320 context to the list (in TRQ, the context is the list actually).
6322 So, I defined SilcDList that can be used for the purpose where
6323 predefined list structure does not exit. This can be used as
6324 such list. Now some context just can be added to the SilcDList.
6325 Currently this list is not used in the SILC just yet, though there
6326 are a lot places where this can replace dynamically allocated
6327 tables and I will fix these places, later, to use SilcDList.
6328 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6329 and use TRQ internally).
6331 Also fixed some annoying warning messages that the original TRQ
6332 code generated. Also minor changes to TRQ's Makefile.in.
6334 * Added support for querying by Client ID to both WHOIS and
6335 IDENTIFY commands into server, as required by the protocol.
6337 * Removed method function pointers from SilcBuffer structure. They
6338 weren't used to anything and just increased the context size for
6339 no good reason. This change also made silc_buffer_alloc and
6340 silc_buffer_free functions inline functions.
6342 * Disabled command flooding detection support until it's fixed so
6343 that it accepts commands in but does not execute them more than once
6346 * Added silc_net_localhost(), to return local hostname, into
6347 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6348 that must be initialized before calling silc_client_init.
6350 * Added new function: silc_server_send_notify_on_channels to send
6351 notify messages to all channels client has joined. It is assured
6352 that the message is sent only once per client.
6354 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6355 lib/silcutil/silcutil.[ch] as silc_format function. The new
6356 function is generic and is used by server as well, not only by
6357 the logging routines.
6359 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6360 the provided version string was not acceptable. Added new function:
6361 silc_ske_check_version into lib/silcske/silcske.h. The function
6362 must be implemented by the application (client or server) and it
6363 does not reside in the SKE library. The function checks the version
6364 string remote end sent.
6366 * Added back pointers (to opaque context and to SilcSocketConnection)
6367 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6369 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6370 duplicate packet context structure.
6372 * Changed `notify' client operation to send same arguments as client
6373 receives from server except for ID's. ID's are mapped to correct
6374 ID entry and that is returned. Also, if channel entry is not sent
6375 by server but the notify is for channel the channel entry is sent
6376 to application (otherwise application doesn't know that it is for
6377 channel (library gets it from packet's Destination ID)).
6379 * Added silc_client_remove_from_channels into client library to
6380 remove a client from all channels it has joined to. Used when
6381 received SIGNOFF notify from server. Added also new function
6382 silc_client_replace_from_channels to replace old ID entry with
6383 new ID entry on all channels. Used when received NICK_CHANGE
6386 * Fixed ID Cache list handling in silc_idlist_get_client in
6387 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6388 to get (or query) client by ID.
6390 * Updated TODO list.
6392 * Added connection authentication status message defined by the
6393 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6394 support for these into the code in client and server side.
6396 * Added generic function silc_client_send_command to send any command
6397 with variable argument list. Application should use this function
6398 to send commands if the command functions provided by the library
6399 does not suite for the application's user interface needs.
6401 * Added new `failure' client operation. Application is notified about
6402 received failure packet if client is executing a protocol. In this
6403 case the protocol's execution has failed.
6405 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6406 is required by the protocol.
6408 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6409 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6412 * Added status flag to SilcSKE object to indicate realtime status
6413 of the SKE protocol.
6415 * Application receives now exactly same command reply arguments as
6416 the library receives from server. However, if ID is received the
6417 corresponding ID entry is returned to the application (eg. Client
6418 ID is mapped to correct SilcClientEntry entry and that is returned).
6419 Changed command_reply client operation due to this change.
6421 * Changed all ID's in commands and in command replys as ID Payloads.
6422 Change affected both client and server side codes.
6424 All ID's sent in SILC network (with execption of ID's in SILC
6425 Packet header) are sent in ID Payload to support variable length
6428 * Server now notifies nick changes and notifies all clients on
6429 the channels about the new nickname (about the new Client ID,
6432 * Implemented CMODE command to change channel modes. Supports all
6433 channel modes defined by the protocol specs except ban and invite
6434 lists. (Also, private channel key mode is supported but support for
6435 setting private channel key in client is missing, thus, this mode
6436 has no effect on client side (except that server requires that the
6437 client uses private channel key and normal channel traffic does not
6440 Also, invite mode works per se, but INVITE command does not work
6441 yet correctly, so you can set channel as invite only channel but
6442 inviting clients to the channel does not work (it is yet to be
6443 thought what's the best way to do it).
6445 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6446 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6447 Implemented CUMODE command to change user's mode on the channel.
6448 Supports all modes defined by the protocol specs.
6450 * Added NAMES command reply to return users modes on the channel.
6452 * Removed unnecessary and slow ciphers from lib/silccrypt.
6454 * Set SO_KEEPALIVE option to connection sockets by default.
6456 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6458 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6459 redefined the Notify Payload into protocol specs.
6461 * Added silc_id_payload_parse_id to get ID directly from raw
6464 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6466 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6467 accept searching by Client ID as well.
6469 * Added support for LEAVE and SIGNOFF notify types in client library.
6471 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6472 to parse ID Payload from raw data.
6474 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6476 * Added flags parameter into silc_ske_assemble_security_properties
6477 function in lib/silcske/silcske.[ch].
6479 * Changed notify client operation to fit better for notify messages
6480 sent by server. The notify payload received from server is now
6481 passed to the application (after parsing it to SilcNotifyPayload).
6482 It is application's responsibility to retrieve the arguments
6483 from the payload and show the message the way it wants. The message
6484 sent by server is implementation specific.
6486 * Changed public keys to comply with the protocol specification.
6487 Old public keys are not supported anymore and are not compatible.
6489 * Removed nickname from Channel Payload as the latest draft removed
6490 it. The client must resolve the nickname from the NAMES command
6491 reply received when it joined the channel.
6493 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6495 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6497 * Fixed some errors in protocol specification drafts.
6499 * Created lib/silccore/silcnotify.c to implement Notify Payload
6500 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6501 generic payloads described by protocol specifications. The file
6502 includes implementations for ID Payload and Argument Payload.
6504 * Changed Command Payload implementation to use the new Argument
6505 Payload. Changed command_xxxx_payload to command_payload_xxxx
6506 to comply with SILC coding conventions.
6508 * Added suppport for Argument Payload handling in Notify Payload
6509 implementation as protocol requires it. Added the new support
6510 into server and client lib as well.
6512 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6514 * Added support for multiple nicknames on same channel. [n] is
6515 added locally to the nickname if there are more than one same
6516 nicknames on the channel.
6518 * Server now sends all nicknames that matched WHOIS request.
6519 Client also shows the list received from server.
6521 * Added TOPIC command to client side. User can now set and show
6522 current topic on channel.
6524 * Added MOTD command to client and server. Also, server sends the
6525 motd when client connects to the server.
6527 * Changed version strings to comply ISO 8601.
6529 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6531 * Fixed protocol error handling in client library. It should now
6532 cope even if the SKE fails for some reason.
6534 * Made new protocol specification drafts for submitting to IETF.
6536 * Implemented TOPIC command to server in silcd/command.c.
6538 * Added two new notify types into lib/silccore/silcnotify.h:
6539 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6540 notify nickname change and topic setting/change on a channel.
6542 * API change of command_reply operation in client library. The
6543 application gets now the status type received from server as well.
6545 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6547 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6549 * Cras fixed and optimized the packet handling even further and
6550 it should work now. Minor change to the prototype of function
6551 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6553 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6555 * Added new function into lib/silcutil/silcschedule.[ch]:
6556 silc_schedule_with_fd to select() a specified fd. The function
6557 returns after timeout expires or data arrives or goes. The
6558 function is used by packet routines to wait that all data is
6559 received from network.
6561 * Fixed data reading from network in lib/silccore/silcpacket.c.
6562 The code now assures that all data is read from the fd and then
6563 continues packet processing. This was a bug fix since the code
6564 used to drop some data in some circumstances.
6566 * Added new function into lib/silcclient/client.[ch]:
6567 silc_client_start_key_exchange to start key exchange after
6568 connection has been established to server. The code internally
6569 now uses this funtion but its main purpose was to provide it
6570 for applications that perform their own connecting. After
6571 application has created a connection it merely calls this
6572 function to start the key exchange between client and server.
6573 The library takes care of everything else after that.
6575 Updated also lib/silcclient/README to explain the usage of
6578 * Do not send to application information that connection has
6579 been established. Application gets notified it by connect
6582 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6584 * Applied cras's patch to add silc_schedule_one function. The
6585 function runs scheduler once and returns.
6587 * Fixed the scheduler after cras messed it up. The timeout
6588 handling works now as it's supposed to work.
6590 * Added into lib/silccore/ silcnotify.h to include notify
6591 message types support. Changed silc_server_send_notify*
6592 functions, in server.[ch], to support those new notify types.
6593 Added the support for the notify types into client library,
6594 as well. Added new notify client operation into ops.h in
6597 * Changed silc_server_packet_send_to_channel to send normal
6598 packets instead of just channel message packets. The function
6599 is now used to send the notify packets to channels. It is not
6600 used to send channel message packets anymore, as server never
6603 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6604 va_arg()s as it seems to require it nowadays. I guess, if SILC
6605 is compiled with older va_arg() the new code should work anyway.
6607 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6609 * Splitted core library. Core library (lib/silccore) includes
6610 now only SILC protocol specific core (and common) components.
6611 Created new utility library (lib/silcutil) that includes more
6612 generic purpose stuff. The stuff for util library was taken
6613 from the old core library. This was minor and easy split.
6615 * Created SILC Client Library (lib/silcclient) that includes
6616 implementation of the SILC client without user interface. This
6617 was major move from silc/ directory. The code has been changed
6618 so that it is transparent towards the user interface. The
6619 silc/ directory includes now the same user interface as before
6620 and it uses the new client library. Read lib/silcclient/README.
6621 Basicly, the client library performs everything else related
6622 to SILC except user interface handling. Also, configuration
6623 files are considered to be part of user interface and library
6624 does not handle them.
6626 This change also changed a lot of structures, function naming etc.
6627 Most important change was that SilcClientWindow object was
6628 renamed to SilcClientConnection in the client library. Created
6629 also new file lib/silcclient/ops.h. Also added new files
6630 silc/local_command.[ch] and silc/client_ops.[ch].
6632 All these changes were made to make it easier for user interface
6633 designers to create what ever user interface for the SILC client
6636 It is also expected that the server will be moved to lib
6637 directory as well and SILC Server Library will be created;
6638 sometimes in the future.
6640 * Removed Local commands from lib/silccore/silccommand.h as
6641 they are application specific and new client library does not
6642 handle any of those anymore.
6644 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6645 old client implementation in silc/.
6647 * Added support for callback functions in SILC_LOG_* macros.
6648 Application can now set its own callbacks that will be called
6649 instead of using the default functions that will always print
6650 the debug messages to stderr (or stdout). Also, debugging can
6651 now be disabled by setting silc_debug to FALSE and re-enabled by
6652 setting it to TRUE. Note, that logging will still work even
6653 if debugging is disabled.
6655 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6656 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6657 silc_log_reset_debug_callbacks.
6659 * To enable debugging in silc client one must give now -d
6660 option on command line.
6662 * Changed silc_schedule_init to automatically allocate task queues
6663 if they are not allocated before calling it.
6665 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6667 * Added GMP 3.1 into math library.
6669 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6671 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6672 a channel in SILC network. The packet is used by servers and
6673 routers to notify other routers that user has left a channel.
6674 This little feature was missing until now. Added the feature
6675 to protocol specification as well.
6677 Added functions: silc_server_send_remove_channel_user and
6678 silc_server_remove_channel_user into server.[ch].
6680 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6681 lib/silccore/silcpacket.h. However, they are not implemented
6684 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6686 * Fixed joining to a channel and sending channel messages
6687 between server and router. The channel message sending should
6688 now work inside a cell.
6690 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6692 * Fixed the private message sending between server and router.
6693 The private message sending should now work inside a cell.
6695 * Added silc_server_replace_id into server.[ch] to replace
6696 existing ID in the SILC network.
6698 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6699 and silc_idlist_replace_server_id into idlist.[ch] in server.
6701 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6703 * Fixed the server to server connections. Server can again now
6704 connect to router. Router to router connections probably does
6707 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6709 * Added dynamic protocol registering support. Now protocols can
6710 registered and unregistered on the fly. Patch by cras.
6712 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6714 * Added lib/contrib directory to hold routines that some platforms
6715 don't have but are needed by SILC.
6717 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6718 into lin/contrib to provide getopt() and getopt_long() for
6719 those who don't have it.
6721 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6723 * Added AWAY command to client. When away message is set and
6724 client receives a private message packet the client automatically
6725 replies to the sender with the away message.
6727 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6728 bug seemed to be the cause of recent problems when compiling
6731 * Added version detection support to SKE protocol specification
6732 and added the new changes to the SKE implementation as well.
6733 There were other minor changes in the SKE protocol as well.
6735 Many changes in lib/silcske/silcske.[ch] and in
6736 lib/silcske/payload.[ch].
6738 * Added ^U functionality, clear input line. Patch from cras.
6740 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6742 * Mainly small bugfixes on core library. Fixed some debugging
6743 logging and buffer overflow in silclog.c.
6745 * Updated config.sub and config.guess on the distribution tree.
6747 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6749 * Added command lagging support in server. Client may execute
6750 commands now only once in two seconds.
6752 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6754 * Optimized packet reception. MAC computation and checking is now
6755 also more optimized. A lot previously duplicated code is now
6756 used as generic by both client and server.
6758 * Fixed key pair generation in clientutil.c
6760 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6762 * Added into lib/silccore/silcbufutil.[ch] new function;
6763 silc_buffer_realloc.
6765 * Moved generic packet sending/encryption functions to
6766 lib/silccore/silcpacket.[ch] from client and server. Some
6767 rewriting of the functions.
6769 * Moved all generic packet reception/decryption functions to
6770 lib/silccore/silcpacket.[ch] from client and server. The
6771 packet processing is now much cleaner in both client and server.
6772 These were major changes in both client and server.
6774 * Created many common functions in server to do packet sending.
6775 Previously code were duplicated a lot, this has been removed
6778 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6780 * Rewrote major parts of the ID cache system. Don't know
6781 whether it is better now or not but at least the API is more
6784 * Major rewrite on ID cache stuff on client because of the ID
6785 cache API changes. Added idlist.c to client.
6787 * Also major rewrite on ID cache stuff on server as well.
6788 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6789 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6790 in hand, instead they are all put into the ID cache system now.
6791 All server_idlist_* routines uses ID cache now instead of
6792 traversing its own lists (those lists does not exist anymore).
6793 SilcIDList though still exists. Also, SilcXXXEntry's are
6796 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6798 * Finally made the SKE implementation compliant to the protocol
6799 specification. All mp integers are now binary encoded as
6800 opposed being HEX encoded.
6802 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6805 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6806 functions: silc_[encode/decode]_pem. Also added function
6807 silc_encode_pem_file to PEM encode with newlines ('\n') for
6810 * SILC public keys are now encoded either PEM or binary. Same
6811 option is for private keys as well. By default private keys
6812 are binary encoded and public keys PEM encoded. Silly HEX
6813 encoding were removed.
6815 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6816 function to create fingerprints.
6818 * Fixed a bug in SHA1; does not change the original data anymore.
6820 * Partly implemented INFO command on client and server side.
6821 Fixed CLEAR command. Changes to SERVER command; show current
6822 server(s) when giving command without arguments. Added
6823 VERSION command to client.
6825 * Added check to server that unregistered connections cannot
6826 execute commands (unless it is specificly allowed).
6828 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6830 * Fixed screen refresh.
6832 * Fixed channel joining bug from client. On some circumstances
6833 client tried to join to a channel it had already joined.
6835 * Added public key verification process into client's protocol.c.
6836 The client now verifies the public key from user and saves
6837 it into ~./silc/serverkeys/ directory.
6839 Added into: clientutil.[ch]: silc_client_verify_server_key.
6841 * Changed SKE protocol's silc_ske_initiator_finish function
6842 to accept callback function that verifies the received public
6843 key. Removed old silc_ske_verify_public_key function.
6845 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6847 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6848 silc_pkcs_private_key[_data]_set.
6850 * Made the password and public authentication more cleaner in
6851 server's protocol.c.
6853 * Removed historic and obsolete protocol `channel_auth' from
6854 both client and server.
6856 * Removed wrong way of sending command status messages from
6857 server to client in server's command.c. The old way violated
6858 protocol specification.
6860 Changes to silccore/silccommand.[ch]: removed
6861 silc_command_encode_status_payload -> not needed anymore,
6862 changed silc_command_encode_payload_va to accept extra
6863 argument on variable argument list. The argument type must
6864 now be provided to the function. Also, added new function:
6865 silc_command_encode_reply_payload_va which is same as
6866 normal command_encode_payload_va except command status type
6867 is provided as extra argument.
6869 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6871 * Added ~./silc directory handling. The directory includes the
6872 public and private keys for the client.
6874 Added silc_client_check_silc_dir, silc_client_create_identifier
6875 and silc_client_load_keys.
6877 * Implemented SILC protocol compliant public key. Added public
6878 and private key saving to and loading from files.
6880 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6881 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6882 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6883 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6884 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6886 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6887 silc_pkcs_load_[public/private]_key.
6889 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6891 * Added silc_server_get_route (route.[ch]) to get connection
6892 data for the fastest route for given ID.
6894 * Implemented INVITE command on client and server. The command
6895 were re-defined in the SILC Protocol Specification and the
6896 implementation now complies with the specification.
6898 * Implemented PING command on client and server.
6900 * Implemented NAMES command on client and server. The server side
6901 supports currently only normal server not router server yet.
6902 Some changes to NAMES definition in SILC protocol specification.
6904 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6906 * Implemented LEAVE command on client and server.
6908 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6909 again. This change was made to the protocol as well. Server
6910 should not violate the protocol specification anymore.
6912 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6914 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6915 was tested. SOCKS4 was not but should work anyway.
