1 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed a bug in hash table internal routine for traversing
4 the table with foreach callback. The current entry may
5 become invalid in the callback but it was referenced after
8 Do not allow auto rehashing of hash table during the
9 silc_hash_table_foreach operation, for same reasons as it is
10 not allowed for SilcHashTableList. Affected files are
11 lib/silcutil/silchashtable.[ch].
13 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
15 * Defined DLLAPI into silcincludes.h and silcwin32.h for
16 Win32 DLL. extern's in header files are now declared with
19 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
21 * Fixed private message handling. It used some old code that
22 caused the client to crash. Affecte file is
23 lib/silcclient/client_prvmsg.c.
25 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
27 * Added function silc_client_add_channel,
28 silc_client_replace_channel_id, and removed functions
29 silc_client_new_channel_id and silc_idlist_get_channel_by_id
32 * Added cross reference of the joined channels to the
33 SilcClientEntry, and changed the SilcChannelEntry's
34 users list to SilcHashTable. The affected files are
35 lib/silcclient/idlist.[ch].
37 * Fixed a bug in hash table tarversing. While the hash table
38 is traversed with SilcHashTableList the table must not be
39 rehashed. It is now guaranteed that auto rehashable tables
40 are not rehashed while tarversing the list. Also defined that
41 silc_hash_table_rehash must not be called while tarversing
42 the table. Added function silc_hash_table_list_reset that must
43 be called after the tarversing is over. The affected files are
44 lib/silcutil/silchashtable.[ch].
46 * Changed all hash table traversing to call the new
47 silc_hash_table_list_reset in server and in client library.
49 * Added function silc_client_on_channel to return the
50 SilcChannelUser entry if the specified client entry is joined
51 on the specified channel. This is exported to application as
52 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
54 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
56 * Fixed founder regaining problem with JOIN command on normal
57 server. The notify for mode change must be sent always and
58 not only if !cmd->pending. Affected file silcd/command.c.
60 * Fixed the WHOWAS command's reply sending to support the
61 lists correctly. Affected file silcd/command.c.
63 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
65 * When sending JOIN command to router for processing the
66 sender's old command identifier was not saved back to the
67 sender's command context, fixed now. The affected file is
70 * Create the key in JOIN command of the router did not return
71 the channel key, added check for this. Affected file is
74 * Fixed a channel ID update bug in JOIN command reply. Do
75 not directly upgrade the ID but call the function
76 silc_idlist_replace_channel_id if the ID was changed.
77 Affected file silcd/command_reply.c.
79 * Fixed memory leaks from command calling if it would fail.
80 Affected file silcd/command.c.
82 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
84 * Applied patches from cras:
86 Memory leak fixes around libaries, irssi window resize fix,
87 new silclist.h and silcdlist.h, all extern inline changed to
90 * Removed dotconf from lib/dotconf, not needed anymore.
92 * Removed TRQ from lib/trq, not needed anymore.
94 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
95 with server connections. Later this will be configurable
96 in config file after new config file is done. Affected file
99 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
101 * Fixed a crash in server related to channel announcements.
102 Affected file silcd/server.c.
104 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
106 * Fixed memory leaks in silc_server_create_new_channel*
107 functions. Affected file silcd/server.c.
109 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
110 which ID was changed. This way the router will send the
111 user list for the channel again, and server won't be in
112 desync in some rare circumstances. Affected file is
113 silcd/packet_receive.c.
115 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
117 * Check for NULL socket pointer in the function
118 silc_server_packet_send_to_channel_real. Affected file
121 * Fixed the BAN notify handling to correctly remove ban
122 list. Affected file silcd/packet_receive.c.
124 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
126 * Fixed some header addition to Toolkit distribution in
127 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
129 * Added lib/silcclient/client_ops_example.h as an template
130 file for application programmers to quickly start using
131 the SilcClientOperation functions in their application.
132 Updated the lib/silcclient/README as well to tell about this
133 nice file made available.
135 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
137 * Call silc_server_remove_from_channels when removing client
138 entry when NO_SUCH_CLIENT_ID was received. Affected file
139 is silcd/command_reply.c.
141 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
143 * Added server & router operator statistics updating. Affected
144 file silcd/packet_receive.c and silcd/command.c.
146 * Fixed the SERVER_SIGNOFF notify handling on normal server
147 not to save the history information for clients. Same was
148 fixed earlier in remove_clients_by_server function, but not
149 here. Affected file silcd/packet_receive.c.
151 * Raised the default connection-retry count from 4 to 7 in
152 server. Affected file silcd/server.h.
154 * Cancel any possible reconnect timeouts when we start the
155 key exchange. Affected file silcd/server.c.
157 * Do not reconnect on connection failure when SCONNECT was
158 given. Affected files silcd/server.[ch].
160 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
162 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
164 * Fixed the NICK command to always give the unformatted
165 nickname to the one giving the NICK command. If unformatted
166 nickname is cached already it will be formatted and the
167 local entry will always get the unformatted nickname.
168 Affected file lib/silcclient/idlist.c.
170 * Fixed some double frees from client library commands.
171 Affected file is lib/silcclient/command.c.
173 * Fixed CUMODE command in server to assure that no one can
174 change founder's mode than the founder itself, there was a
175 little bug. Affected file silcd/command.c.
177 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
179 * Removed the SilcClientCommandDestructor from the client
180 libary, it is not needed anymore. Affected files are
181 lib/silcclient/silcapi.h, command[_reply].[ch],
182 client_notify, idlist.c.
184 * Fixed GETKEY command to first resolve client, and then
185 resolve the server only if the client was not found, instead
186 of resolving both at the same time. Affected file is
187 lib/silcclient/command.c.
189 * Added silc_client_start_key_exchange_cb and lookup the
190 remote hostname and IP address before starting the key
191 exchange with server. The affected file is
192 lib/silcclient/client.c.
194 * The server's public key is now saved using the IP address
195 of the server and not the servername for the filename.
196 The hostname public key filename is checked as an fall back
197 method if the IP address based filename is not found.
199 Fixed the GETKEY command to save the fetched server key
202 Print the remote server's hostname now when new key is
203 received during connection process. Affected file is
204 irssi/src/silc/core/client_ops.c.
206 * Return always our own public key to the client if it asks
207 for it with GETKEY command. Affected file silcd/command.c.
209 * Removed the use_auto_addr variable from default config
210 file since it was in wrong section. Affected file is
213 * Fixed TOPIC_CHANGE notification to not route it when it
214 was sent using silc_server_send_notify_to_channel function.
215 Affected file silcd/command.c.
217 * Fixed silc_server_send_notify_kicked to send the kicker's
218 Client ID also, it was missing. Affected files are
219 silcd/command.c, silcd/packet_send.[ch].
221 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
223 * Do not save client history information in SERVER_SIGNOFF.
224 Fixes the bug in normal server that it does not detect
225 the client becoming valid after the server becomes back
226 online. Affected file silcd/server_util.c.
228 * Added `sock_error' field into the SilcSocketConnection
229 context. When error occurs during socket operation (read
230 or write) the error is saved. Added also new function
231 silc_socket_get_error to return human readable socket error
232 message. Affected files are lib/silcutil/silcsockconn.[ch],
233 lib/silcutil/unix/silcunixsockconn.c, and
234 lib/silcutil/win32/silcwin32sockconn.c.
236 * The server now prints the socket error message in the
237 signoff for client. Affected file silcd/server.c.
239 * Fixed the `created' channel information sending from router
240 to server in JOIN command. Checks now whether the channel
241 really was created or not and set it according that.
243 Fixed the JOIN command to use the client entry's current
244 ID during the joining procedure instead of the one it sent
245 in the command (it is checked though), since it can change
246 between the packet processing and command processing, and
247 would just case unnecessary pain in the client end. Affected
248 file silcd/command.c.
250 * Fixed a channel key payload sending to use correct channel
251 ID when the server was forced to change the channel's ID by
252 router. Router sent the key payload with the old Channel ID.
253 Affected file silcd/packet_receive.c.
255 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
257 * Call silc_server_save_channel_key only if the key payload
258 was provided in the JOIN command's command reply. Affected
259 file silcd/command_reply.c.
261 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
263 * Fixed silc_mp_sizeinbase to return the value correctly with
264 MPI. Affected file lib/silcmath/mp_mpi.c.
266 * Fixed the stop_server signal to correctly stop the scheduler
267 and gracefully stop the server when SIGTERM or SIGINT signals
268 are received. Affected file silcd/silcd.c.
270 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
272 * Simple handling of TERM and HUP signals. Also added some log
273 flushing call around. Affected file is
276 * Fixed small bugs in silclog.c. Now buffering output will take
277 effect after 10 seconds since startup: This will ensure that
278 no important startup messages are lost. Also output redirection
279 will preserve original format ([Date] [Type] message).
280 Affected file is lib/silcutil/silclog.c.
282 * Added two options to the config file, in the logging section:
283 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
284 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
286 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
288 * Do not print the warning about log files not being initialized
289 more than once to avoid excess logging. Affected file is
290 lib/silcutil/silclog.c.
292 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
293 the SIM copying in make install in Makefile.am.pre.
295 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
297 * Rewritten silclog APIs. Globally interesting changes follows:
298 silc_log_set_files() changed to silc_log_set_file().
299 silc_log_set_callbacks() changed to silc_log_set_callback().
300 ROBOdoc documented silclog header file.
301 SilcLogCb now returns bool to wether inihibit the default
302 handler or not (to keep the old behaviour return always TRUE).
303 The new APIs should also fix the problem of the
304 silcd_error.log file that was written in the current directory.
307 Log files streams will remain opened after silc_log_set_file()
308 call, means less CPU usage notably on high traffic servers.
309 File streams are now full buffered, and flushed to the disk
310 every 5 minutes, lesses HD activity and CPU usage.
311 Messages can be redirected, allowing admins to configure
312 one single logfile for all server messages.
313 the silc_log_quick global variable to activate fast-logging.
314 Affected files lib/silcutil/silclog.[ch]
316 * Changed some code to conform new silclog APIs. Affected
317 files are doc/example_silcd.conf.in, silcd/server.c
318 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
321 * Fixed a memory leak that could occur in some situations.
322 Affected file silcd/serverconfig.c.
324 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
326 * Added the silc_client_del_client to remove the client from
327 all channels as well. Affected file lib/silcclient/idlist.c.
329 * Fixed the client library to correctly remove the client
330 from all channels when the client entry is being destroyed.
331 Affected file lib/silcclient/client_notify.c, command.c.
333 * Added auto-nicking support to the client library. If the
334 applicatio now sets client->nickname it will be sent to the
335 server after connecting by the library. This way for example
336 SILCNICK (or IRCNICK) environment variables will have effect
337 and always change the nickname automatically to whatever
338 it is wanted. Affected file lib/silcclient/client.[ch].
340 * Renamed silc_server_command_bad_chars to the
341 silc_server_name_bad_chars and moved it to the
342 silcd/server_util.[ch]. Added also new function
343 silc_server_name_modify_bad to return nickname that
344 includes bad characters as new nickname without those
345 bad characters. This check and modify is now used in
346 silc_server_new_client when the username is initially set
347 as nickname, so it must be checked to be valid nickname.
348 Affected file silcd/packet_receive.c.
350 * The nickname length is now taken from the packet for real
351 and not trusted to strlen() since it clearly can return
352 wrong length for nickname including bad characters. This
353 also applies to channel names. Affected file silcd/command.c.
355 * Removed the lib/silcsilm/modules directory. Modules are now
356 compiled into the lib/silcsim. Fixed the copying of the
357 modules to follow symbolic links in Makefile.am.pre.
359 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
361 * Fixed silc_string_regexify list creation. Fixes bugs with
362 BAN and INVITE commands in server. The affected file is
363 lib/silcutil/unix/silcunixutil.c.
365 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
367 * Removed the command destructor entirely from the server's
368 command and command reply routines. It is not needed, and
369 its usage was buggy and caused crashes. Affected files are
370 silcd/command[_reply].[ch].
372 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
374 * Cancel protocol and NULL sock->protocol if timeout
375 occurred during protocol. Affected file silcd/server.c.
377 * Cancel protocol timeouts always before calling the final
378 callback, to assure that after final callback is called
379 no other state will be called for the protocol anymore.
380 Affected file silcd/protocol.c.
382 * Print error log if incoming connection configuration could
383 not be found. Affected file silcd/server.c.
385 * Fixed JOIN command to correctly save the founder mode
386 to the client on normal SILC server, when the channel
387 was created by the router. Affected file silcd/command.c.
389 * Fixed LIST command (hopefully) to send correct reply
390 packets. Affected file silcd/command.c.
392 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
394 * The silc_packet_receive_process now returns FALSE if the
395 read data was invalid packet, and TRUE if it was ok.
397 The server now checks that if unauthenticated connection
398 sends data and its processing fails the server will close
399 the connection since it could be a malicious flooder.
401 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
403 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
405 * Make sure the warning about error opening a log file is
406 printed only once and not everytime it fails (produces
407 too much useless log). Affected file lib/silcutil/silclog.c.
409 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
411 * Made the silc_server_daemonise() function more readable.
412 Affected file silcd/server.c.
414 * Pid file is now optional, the user may comment it out from
415 the config file. Removed define SILC_SERVER_PID_FILE, we
416 don't need a default any longer. Affected file
417 configure.in.pre, lib/Makefile.am.pre.
419 * Make some use of the pid file. The server now dies at startup
420 if it detects a valid pid file on his path. The server would
421 die anyway in this circumstance, because of the bind() failure.
422 Affected file silcd/silcd.c.
424 * No longer compiling lib/dotconf.
426 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
428 * Fixed JOIN command parsing not to crash. Affected file
429 lib/silcclient/command.c.
431 * Fied the NICK_CHANGE notify to add the new client entry
432 even it is resolved. This removes an <[unknown]> nick
433 thingy bug in the client. Affected file is
434 lib/silcclient/client_notify.c.
436 * Do not try to allocate 0 bytes (efence does not like it)
437 in lib/silccore/silccomand.c when encoding payload.
439 * Do not take IRCNICK as nickname in Irssi SILC client since
440 it is not possible to set nickname before hand connecting
441 the server (TODO has an entry about adding auto-nicking
444 * Changed the silc_server_command_pending to check whether
445 there already exists an pending entry with the specified
446 command, command identifier and pending callback. This is
447 to fix IDENTIFY and WHOIS related crashes that may register
448 multiple pending commands with same identifier. Affected
449 file silcd/command.c.
451 * Fixed the server to reconnect to the router even if it
452 was already reconnecting and EOF was received. This to
453 fix a possibility that the server wouldn't ever try to
454 auto-reconnect to the router. Affected file silcd/server.c.
456 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
458 * Fixed the server's password authentication to use the
459 length of the locally saved password, and not the one
460 sent in the packet. Affected file silcd/protocol.c.
462 * Fixed same password authentication problem in the
463 Authentication Payload handling routines in
464 lib/silccore/silcauth.c.
466 * Yet another password authentication problem fixed with
467 channel password handling in silcd/command.c.
469 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
471 * If first character of string in silc_parse_userfqdn is '@'
472 then do not parse it. Affected file is
473 lib/silcutil/silcutil.c.
475 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
477 * Fixed minor bug in IDENTIFY command reply sending, which
478 caused various weird problems during JOIN when it was
479 resolving names for users. Affected file silcd/command.c.
481 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
483 * Fixed the IDENTIFY command reply sending to chech better valid
484 clients. It was possible to send incomplete list of replies.
485 Affected file silcd/command.c.
487 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
489 * Added silc_client_command[s]_[un]register functions now to
490 dynamically register the commands in client library. Removed
491 the static table of commands. This allows the client library
492 to call commands without causing the application to know about
493 what commands library has called.
495 Removed the INFO command reply kludge to detect when the command
496 was called by library. Now library use its own command reply
497 function for INFO command.
499 Added function silc_client_command_call to call a command.
500 Application can use it to call command, not access the structure
503 Now all commands that are sent by the client library (not
504 explicitly sent by application) use own command reply functions.
506 Affected files around lib/silcclient/ and in
507 irssi/src/silc/core/.
509 * Fixed the WHOIS command reply sending to chech better valid
510 clients. It was possible to send incomplete list of replies.
512 Fixed the WHOIS and IDENTIFY to send the request to router
513 if normal server did not do it and did not find any results.
515 Affected file silcd/command.c.
517 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
519 * Moved the internal data from SilcClient context into its
520 own file, not accesible to application. Affected files
521 lib/silcclient/client.h and lib/silcclient/client_internal.h,
522 and other files in client library.
524 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
526 * Added doc/examples installation target in Makefile.am.pre.
529 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
531 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
532 commands the found client entry will be removed from the
533 cache, after notifying application about the error. Affected
534 file lib/silcclient/command_reply.c.
536 * Changed the /MSG to check for exact nickname user gave, and
537 not let `nick' match `nick@host' if it is only one found. Now,
538 user must type the exact nickname (like nick@host2) even if
539 there are no more than one same nicks found. This is to avoid
540 a possibility of sending nickname to wrong nickname since
541 `nick' could match `nick@host'. Affected file is
542 irssi/src/core/silc-servers.c.
544 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
546 * Do not print "you are now server operator" or similar when
547 giving /away command. Affected files are
548 irssi/src/silc/core/client_ops.c, silc-servers.h.
550 * Made the silc_server_command_pending_error_check to send
551 the same command reply payload it received back to the
552 original sender of the command. This way all arguments
553 that was received by the server will be received by the
554 client too. Affected file silcd/command.c.
556 * Added the silc_idcache_add to return the created cache entry
557 to a pointer. Affected file lib/silccore/silcidcache.[ch].
559 * Add global clients to expire if they are not on any channel.
560 This is because normal server will never know if they signoff
561 if they are not on any channel. The cache expiry will take
562 case of these entries. This is done by normal servers only.
563 The affected files are silcd/command_reply.c,
564 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
566 * If server receives invalid ID notification for WHOIS or
567 IDENTIFY and the ID exists in the lists, it is removed.
568 Affected file silcd/command_reply.c.
570 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
571 in client then client entry that it matches is searched and
572 the nickname is printed on the screen for user. Affected
573 file irssi/src/silc/core/client_ops.c.
575 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
577 * Use cache entry expire time in the LIST command reply to
578 purge old entries from the cache after the LIST command
579 reply has been received. This way we don't have non-existent
580 entries in the cache for too long. Affected file is
581 silcd/command_reply.c.
583 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
585 * If we are normal server, and we've not resolved client info
586 in WHOIS or IDENTIFY from router, and it is global client,
587 we'll check whether it is on some channel. If it is not
588 then we cannot be sure about its validity and will resolve it
589 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
590 file silcd/command.c.
592 * Search channel by name (if possible) rather than by ID
593 in IDENTIFY command's command reply. Affected file is
594 silcd/command_reply.c.
596 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
598 * Distribute to the channel passphrase in CMODE_CHANGE notify.
599 Updated specs and implemented it. Affected file silcd/command.c,
600 silcd/packet_send.c and silcd/packet_receive.c.
602 * Implemented the <founder auth> payload handling in the JOIN
603 command. If provided all conditions for channel joining
604 except requirement to provide correct passphrase can be
605 overrided by the channel founder. Updated the protocol specs.
606 Affected file silcd/command.c.
608 Added support for founder auth in JOIN command in client
609 library. Fixed the parsing of the JOIN command now to support
610 all options as they should be. The affected file is
611 lib/silcclient/command.c.
613 * Optimized the WHOIS and IDENTIFY commands to send the request
614 to router only if it includes nicknames or other names. If
615 they include only IDs then check the local cache first before
616 routing. Affected file is silcd/command.c.
618 * Added channels topic announcements. Affected file is
619 silcd/packet_receive.c and silcd/server.c.
621 * Fixed the silc_server_send_notify_topic_set to really destine
622 the packet to channel. Affected file silcd/packet_send.c.
624 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
625 library. Affected file lib/silcclient/client_notify.c.
627 * Added UMODE announcements. Affected file silcd/server.c.
629 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
631 * Memory leak fixes in:
633 lib/silcutil/silcsockconn.c
634 lib/silcske/silcske.c
637 lib/silccrypt/silcpkcs.c
638 lib/silccore/silccommand.c
639 lib/silccore/silcidcache.c
644 * ROBOdoc documented the lib/silcske/groups.h file and a
645 bit changed the interface for better.
647 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
649 * Update the client entry context in the ID cache after
650 nick change. Affected file lib/silcclient/command.c.
651 Fixes the CUMODE command when regaining founder privileges,
652 and a little WHOIS problem.
654 * Fixed silc_net_gethostbyname to correctly call the
655 inet_ntop. Affected file lib/silcutil/silcnet.c.
657 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
659 * Added IPv6 support checking to the configure.in.pre, added
660 also --enable-ipv6 option to override the check. Affected
661 file configure.in.pre.
663 * The silc_thread_create now calls the start function
664 directly if threads support is not compiled in. Removes
665 ugly #ifdef's from generic code. Affected files are
666 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
668 * Added silc_net_gethostby[name/addr]_async to asynchronously
669 resolve. Affected files are lib/silcutil/silcnet.[ch].

680 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
681 routines. Added silc_net_is_ip[4/6]. Affected file is
682 lib/silcutil/unix/silcunixnet.c. All routines that take
683 address as argument now supports both IPv4 and IPv6 addresses.
685 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
687 * Fixed LIST command reply sending in server. Affected file
690 * Server now sends the kicker's client ID in the KICK notify
691 to the kicked client. Affected file silcd/command.c.
693 * The client library now parses the kickers client ID and
694 UI displays it. Affected files lib/silcclient/client_notify.c
695 and irssi/src/silc/core/silc-channels.c, module-formats.c.
697 * Made all payload parsing function prototypes consistent.
698 They all take now const unsigned char * and uint32 pair as
699 the payload data instead of SilcBuffer. Changes all around
700 the source tree. Other unsigned char* -> const unsigned char*
701 changes around the tree as well.
703 * Optimized SFTP client and server packet sending not to
704 allocate new buffer for each packet but to recycle the
705 first allocated buffer. Affected files are
706 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
708 * Optimized the SFTP client to use SilcList instead of
709 SilcDList for requests, because it is faster. Affected file
710 is lib/silcsftp/sftp_client.c.
712 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
713 into lib/silccore/silcid.[ch].
715 Renamed silcpayload.[ch] into silcargument.[ch].
717 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
719 * If client entry is deleted with active key agreement
720 session, abort the session.
722 The silc_client_abort_key_agreement now calls the completion
723 callback with new SILC_KEY_AGREEMENT_ABORTED status.
725 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
728 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
730 * Don't use __restrict in older GCC's. Affected file is
731 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
733 * silc_net_localhost now attempts to reverse lookup the
734 IP/hostname. Affected file lib/silcutil/silcnet.c.
736 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
737 command. It can be used to gain founder privileges at
738 the same time when joining the channel.
740 Defined that the SILC_NOTIFY_TYPE_KICKED send the
741 kicker's client ID as well. Updated protocol specs.
743 Defined that the server must send SILC_COMMAND_IDENTIFY
744 command reply with error status to client who sent
745 private message with invalid client ID.
747 Updated the protocol specification.
749 * Added silc_server_send_command_reply to send any
750 command reply. Affected file silcd/packet_send.[ch].
752 * Added silc_id_payload_encode_data to encode ID payload
753 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
755 * The server now send IDENTIFY command reply with error
756 status if client ID in private message is invalid. Affected
757 file silcd/packet_receive.c.
759 * Save the server key file with server's IP address in
760 the filename instead of hostname. The affected file is
761 irssi/src/silc/core/client_ops.c.
763 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
765 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
768 * Added libtool support for compiling shared objects in
769 lib/silcsim. Affected file configure.in.pre and
770 lib/silcsim/Makefile.am. Original patch by cras.
772 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
774 * Pid file configuration, and server's config file fixes
775 patch by toma. Updated CREDITS file.
777 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
779 * Fixed silc_client_channel_message to not try to decrypt
780 the message twice if it resolved the destination client
781 information. This could cause of dropping one channel
782 message. Affected file lib/silcclient/client_channel.c.
784 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
786 * Added silc_client_run_one into lib/silcclient/silcapi.h and
787 lib/silcclient/client.c. This function is used when the SILC
788 Client is run under some other scheduler, or event loop or
789 main loop. On GUI applications, for example this may be
790 desired to used to run the client under the GUI application's
791 main loop. Typically the GUI application would register an
792 idle task that calls this function multiple times in a second
793 to quickly process the SILC specific data.
795 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
797 * Fixed silc_server_drop() for dropping the supplementary
798 groups as well, this could cause a security hole on some
801 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
803 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
806 * Write PID file after dropping privileges. Added -F option
807 to run server on foreground. A patch by debolaz.
808 Affected files silcd/server.c, silcd/silcd.c.
810 * Fixed MOTD to return the MOTD file server name. Affected
811 file silcd/command.c.
813 * Added INFO command reply handling to the Irssi SILC Client.
814 Affected file irssi/src/silc/core/client_ops.c.
816 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
818 * Fixed the silc_idcache_list_* routines to really support
819 the dynamic list. Fixes a crash. Affected file is
820 lib/silccore/silcidcache.c.
822 * Fixed the LIST command reply to really call LIST command's
823 pending callbacks. Affected file silcd/command_reply.c.
825 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
827 * Update conn->local_entry->nickname after giving NICK
828 command. Affected file lib/silcclient/command.c.
830 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
832 * Added the [pid] option to the silcd configuration file
834 Affected files: serverconfig.[ch] and silcd.c
836 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
838 * Save fingerprint in WHOIS command reply in server.
839 Affected file silcd/command_reply.c.
841 * Fixed NICK commands pending callback registration.
842 Affected file lib/silcclient/command.c.
844 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
846 * Use ++server->cmd_ident when sending commands in server,
847 instead of random number. Affected file silcd/command.c.
849 * Fixed GETKEY command reply to call actually GETKEY pending
850 command callbacks. Affected file silcd/command_reply.c.
852 * A bit stricter check for nicknames. Check for same nickname
853 in NICK command also. Affected file silcd/command.c.
855 * Do not call INFO command everytime client ID changes, only
856 during first connecting. Affected file lib/silcclient/client.c.
858 * Set the new nickname only after successful command reply for
859 NICK command is returned by server. Affected file
860 lib/silcclient/command.c.
862 * Remove nicknames from nicklist during server_signoff notify.
863 Should fix /NAMES bit more. The affected file is
864 irssi/src/silc/core/silc-channels.c.
866 * Added `fingerprint' field to the SilcIDListData in the
867 silcd/idlist.h to hold the fingerprint of the client's
870 Send the fingerprint of the client's public key in WHOIS
873 Affected files silcd/command.c, and silcd/idlist.[ch].
875 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
876 create fingerprint from given data.
878 * Show the fingerprint of the client's public key in WHOIS.
879 Affected files irssi/src/module-formats.[ch] and
880 irssi/src/silc/core/client_ops.c.
882 * Format the multiple same nicknames also during JOIN and
883 NICK_CHANGE notifys. Affected file is
884 lib/silcclient/client_notify.c.
886 * Do not print error on screen for invalid private message
887 payload since it can come if someone is sending private
888 messages with wrong key. Affected file
889 lib/silccore/silcprivate.c.
891 * Fixed multiple concurrent /PING crash. Affected file
892 lib/silcclient/command.c.
894 * Changed the wrong ID encoding. All IP addresses must be
895 in MSB first order in encoded format. They were encoded
896 wrong and was in LSB format. Affected files are
897 silcd/serverid.c, lib/silcutil/silcutil.c.
899 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
901 * Call the `connect' client operation through the scheduler
902 in case of error. Affected file lib/silcclient/client.c.
904 * Call the `failure' client operation even if the error
905 occurred locally during a protocol. Affected file is
906 lib/silcclient/protocol.c.
908 * Added support of sending LIST command to router from normal
909 server. This way normal server can get list of all channels
910 in the network too. Fixed the channel list sending in the
911 server too. Affected files are silcd/command.c, and
912 silcd/command_reply.[ch].
914 * Added silc_server_update_channels_by_server and
915 silc_server_remove_channels_by_server. They are used during
916 disconnection of primary router and in backup router protocol.
917 Affected file silcd/server_util.[ch], silcd/server.c and
918 silcd/server_backup.c.
920 * Fixed channel adding to global list in IDENTIFY command
921 reply in server. Affected file silcd/command_reply.c.
923 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
925 * If the incoming packet type is REKEY or REKEY_DONE process
926 that packet always synchronously. Fixes yet another MAC
927 failed error on slow (dialup) connections. Affected file
928 lib/silcclient/client.c and silcd/server.c.
930 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
932 * Call check_version SKE callback for initiator too. Affected
933 file lib/silcske/silcske.c.
935 * Implemented fix for security hole found in the SKE that was
936 fixed in the specification few days back; the initiator's
937 public key is now added to the HASH value computation.
938 Added backwards support for the old way of doing it too, for
939 old clients and old servers. Affected file is
940 lib/silcske/silcske.c.
942 * Enabled mutual authentication by default in SKE. If initiator
943 is not providing mutual authentication the responder will
944 force it. This will provide the proof of posession of the
945 private key for responder. The affected files are
946 lib/silcclient/protocol.c and silcd/protocol.c.
948 * Do not cache anymore the server's public key during SKE.
949 We do mutual authentication so the proof of posession of
950 private key is done, and if the server is authenticated in
951 conn auth protocol with public key we must have the public
952 key already. Affected file silcd/protocol.c.
954 * Added new global debug variable: silc_debug_hexdump. If
955 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
956 file lib/silcutil/silclog.[ch].
958 * Fixed compilation warning due to char * -> const char *.
959 Affected files lib/silcutil/silcnet.h, and
960 lib/silccore/silcauth.[ch].
962 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
964 * Fixed CMODE command when new channel key was created. If
965 the creation failed the old key was removed. Next time giving
966 same command would crash the server since the old key was
967 freed already. Affected file silcd/command.c.
969 * Fixed the silc_server_announce_get_channels to not crash
970 on reconnect. Affected file silcd/server.c.
972 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
974 * Added silc_log_set_debug_string function to set a regex
975 string to match for debug output. Only the function names,
976 or filenames matching the given debug string is actually
977 printed. This way it is possible to filter out those debug
978 strings that user is not interested in.
980 Fixed a bug in silc_string_regexify.
982 Affected files lib/silcutil/silclog.[ch], and
983 lib/silcutil/unix/silcunixutil.c.
985 * Changed the -d options in both server and Irssi SILC client
986 to take the debug string as argument. Affected files
987 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
989 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
991 * Added silc_hash_babbleprint to create a Bubble Babble
992 Encoded fingerprint. The encoding is developed by Antti
993 Huima (draft-huima-babble-01.txt), and it creates human
994 readable strings out of binary data. Affected file
995 lib/silccrypt/silchash.[ch].
997 * Print the babble print now in addition of fingerprint as well
998 in Irssi SILC client. Affected files are
999 irssi/src/fe-common/silc/module-formats.[ch],
1000 irssi/src/fe-common/silc/core/client_ops.c.
1002 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1004 * Fixed a security problem found in SKE. The initiator's
1005 public key too is now added to the HASH hash value creation
1006 which is signed by the responder to create the SIGN value.
1007 This will prevent anyone in the middle to lie to the responder
1008 about the initiator's public key. If this is done now, the
1009 man in the middle will get caught. Updated the protocol
1012 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1014 * Better installation directory handling. Configure module
1015 paths and other paths automatically to example_silc* files
1016 in doc/. A patch by toma.
1018 * Fixed compiler warning from MPI library, and from SILC RNG.
1021 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1022 It can be configured with ./configure. A patch by toma.
1024 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1026 * Find correct make to use in prepare-clean. A patch by
1027 toma. Affected file prepare-clean.
1029 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1031 * Added irssi variables use_auto_addr, auto_bind_ip,
1032 auto_bind_port and auto_public_ip.
1034 * Changed the interface for silc_client_send_key_agreement
1035 in lib/silcclient/silcapi.h
1039 irssi/src/silc/core/silc-core.c
1041 lib/silcclient/silcapi.h
1042 irssi/src/silc/core/silc-channels.c
1043 lib/silcclient/client_keyagr.c
1046 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1048 * Added silc_pkcs_public_key_compare to compare two
1049 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1051 * Check that the client who set the founder mode on the
1052 channel is the same client that is giving the founder
1053 mode to itself. It is done by comparing the saved public
1054 key (it is saved even in the authentication is passphrase).
1055 Affected file silcd/command.c.
1057 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1059 * Do not process packet for disconnected socket connection.
1060 Affected file lib/silccore/silcpacket.c.
1062 * Process the DISCONNECT packet through scheduler in the
1063 client library. Affected file lib/silcclient/client.c.
1065 * Fixed the silc_client_packet_parse to not to increase
1066 the packet sequence number if the conn->sock and the
1067 current socket connection is not same. This can happen
1068 for example during key agreement when the conn includes
1069 multiple socket connections (listeners). Affected file
1070 lib/silcclient/client.c.
1072 * The sender of the file transfer request now provides also
1073 the pointer (listener) for the key exchange protocol. If
1074 the listener cannot be created then it sends empty key
1075 agreement and lets the receiver provide the listener.
1077 Added `local_ip' and `local_port' arguments to the
1078 silc_client_file_send. If they are provided they are used,
1079 if not then it will attempt to find local IP address, if
1080 not found or bind fails then the remote client will provide
1083 Affected files are lib/silcclient/client_ftp.c and
1084 lib/silcclient/silcapi.h.
1086 * Extended the FILE SEND command to support defining the
1087 local IP and port for key exchange listener. They are
1088 optional. Affected file irssi/src/silc/core/silc-servers.c.
1090 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1092 * Defined to WHOIS command reply the sending of fingerprint
1093 of the client's public key (if the proof of posession of the
1094 corresponding private key is verified by the server).
1095 Updated to the protocol specification.
1097 * Added support of receiving the client's public key's
1098 fingerprint in command reply in client library. Affected
1099 file is lib/silcclient/command_reply.c, and
1100 lib/silcclient/idlist.[ch].
1102 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1104 * Do not send over 128 chars long nickname to the server
1105 in NICK command. Affected file lib/silcclient/command.c.
1107 * Do not send over 256 chars long channel names to the server
1108 in JOIN command. Affected file lib/silcclient/command.c.
1110 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1112 * Assure that silc_server_close_connection cannot be called
1113 twice for same socket context. Affected file is
1116 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1118 * Send error message to application if opening file for
1119 writing during file transfer fails. Affected file is
1120 lib/silcclient/client_ftp.c.
1122 Remove all file transfer sessions for a client that we're
1123 removing from ID cache.
1125 Affected file is lib/silcclient/client_ftp.c.

1155 client library. Affected file lib/silcclient/client_prvmsg.c.
1157 * Do not actually remove the client directly from ID cache
1158 during SERVER_SIGNOFF, but invalidate it. This way we
1159 preserve the WHOWAS info for the client. Affected file
1160 silcd/server_util.c.
1162 * Fixed SERVER_SIGNOFF notify handling in the server. The
1163 server is now able to process incoming SERVER_SIGNOFF notify
1164 for a server that it doesn't even know about. It will remove
1165 the clients provided in the notify. Affected file
1166 silcd/packet_receive.c.
1168 * Check for partial packet in data queue after every packet that
1169 was found from the queue. Return and wait for more data if
1170 there is partial data in queue. Affected file is
1171 lib/silccore/silcpacket.c.
1173 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1188 irssi/src/fe-common/silc/module-formats.[ch].
1190 * Wrote a help file for FILE command.
1192 * Added silc_rng_global_get_byte_fast to get not-so-secure
1193 random data as fast as possible. Random data is read from
1194 /dev/urandom if available and from the SILC RNG if not
1195 available. It is used in padding generation. Affected file
1196 lib/silccrypt/silcrng.[ch].
1198 * All packets in client library are now processed synchronously.
1199 Optimized packet processing a lot. Affected file
1200 lib/silcclient/client.c.
1202 * All server connection packets are processing synchronously
1203 now in server, to optimize packet processing. Affected file
1206 * Include files are installed now only in Toolkit distribution
1207 if make install is given. Affected files: all Makefile.am's.

1211 * Assure that silc_client_notify_by_server_resolve does not
1212 resolve the client information multiple times. If it cannot
1213 be found by the first it cannot be found at all. Affected
1214 file lib/silcclient/client_notify.c.
1216 * Fixed WHOWAS command reply calling. Affected file
1217 lib/silcclient/command_reply.c.
1219 * Removed all references to silc_idlist_get_client from the
1220 Irssi SILC client since that call is internal call used by
1221 the library. The Irssi SILC client will use now client
1222 retrieval functions found in silcapi.h.
1224 * Fixed a bug in resolving nickname info before sending
1225 private message. It used freed memory. Affected file
1226 irssi/src/silc/core/silc-servers.c.
1228 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1230 * Assure my_channels statistics cannot go negative in server.
1231 Affected files silcd/server.c, silcd/server_util.c.

1247 * Added silc_net_localip to return local host's IP address.
1248 Affected file lib/silcutil/silcnet.[ch].
1250 * If key exchange or rekey protocol is active for a connection
1251 parse all packets syncronously since there might be packets
1252 in packet queue that we are not able to process without first
1253 processing packets before them. Affected file silcd/server,
1254 lib/silcclient/client.c.
1256 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1257 whether library should continue processing the packet.
1258 Affected file lib/silccore/silcpacket.h.

1304 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1305 is incomplete and is being resolved, it won't be resolved
1308 Make sure also that USERS command reply does not resolve
1309 twice information. Affected file is
1310 lib/silcclient/command_reply.c.
1312 Make sure that silc_client_get_clients_by_list does not
1313 resolve twice same information.
1315 * Check for valid client->id in the silc_server_free_client_data.
1316 Affected file silcd/server.c.
1318 * Fixed /GETKEY nick@server not to crash if the server entry
1319 is not found. Affected file lib/silcclient/command.c.
1321 * Fixed the silc_server_check_cmode_rights to check the
1322 requested modes correctly. Affected file silcd/command.c.

1327 Affected file silcd/command.c.
1329 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1331 * Call the silc_server_udpate_servers_by_server in the
1332 primary router that comes back online in the backup resuming
1333 protocol. Otherwise it routes packets wrong. Affected file
1334 silcd/server_util.[ch], silcd/server_backup.c.
1336 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1338 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1339 lib/silcutil/silcbuffmt.[ch].
1341 * Redefined the SILC packet header to include the padding
1342 length. Affected file lib/silccore/silcpacket.[ch].
1344 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1345 length for maximum padding up to 128 bytes). Affected
1346 file lib/silccore/silcpacket.h.
1348 * Removed all backwards support for old 0.5.x MAC thingies.
1349 The SILC packet header change makes it impossible to be
1350 backwards compatible.
1352 * Send the ENDING packet with timeout in the backup resuming
1353 protocol. This is to assure that all routers has connected
1354 to the primary router. Affected file silcd/server_backup.c.
1356 * Changed the RNG to take the first IV from random data. It
1357 used to take it from zero actually. Changed the RNG also
1358 to use /dev/urandom during session. /dev/random is used
1359 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1361 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1363 * Changed the SILC packet header to have the first two bytes
1364 (the packet length) encrypted. Affected files aroung the
1365 code tree, lib/silccore/silcpacket.[ch]. Removed the
1366 SilcPacketCheckDecrypt callback. It is not needed anymore
1367 since the silc_packet_receive_process will determine now
1368 whether the packet is normal or special.
1370 * Implemented the unidirectional MAC keys. Affected files
1371 lib/silcske/silcske.c, silcd/protocol.c and
1372 lib/silcclient/protocol.c.
1374 * Implemented the packet sequence number to the MAC computation.
1375 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1376 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1377 lib/silcclient/protocol.c.
1379 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1381 * Allow backup router to announce servers. All servers
1382 announced by backup router are added to the global list
1383 automatically. Update hte server's socket to our primary
1384 router also when backup router announces a server.
1385 Affected file silcd/packet_receive.c.
1387 * Do not update the client->router in the function
1388 silc_server_udpate_clients_by_server if the client is on
1389 global list. We might fail to find any specific server
1390 for locally connected clients and local cell clients. They
1391 should still use the `from' and not `to' as client->router.
1392 This fixes backup router resuming protocol. Affected file
1393 silcd/server_util.c.
1395 * Decrease channel statistics count only if the channel
1396 deletion worked. Affected files are silcd/server.c and
1397 silcd/server_util.c.
1399 * Added silc_server_update_servers_by_server to update origin
1400 of all server entries. Used during backup router protocol.
1401 Affected files silcd/server_util.[ch], silcd/server.c. and
1402 silcd/backup_router.c.
1404 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1405 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1406 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1407 lib/silccrypt/silchmac.c.
1409 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1411 * Assure that router cannot reroute the same channel message
1412 to the sender. Affected file silcd/packet_receive.c.
1414 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1416 * Made better checks that the channel message is not sent
1417 to the router it came from. Affected file is
1418 silcd/packet_send.c. Fixed memory leak too.
1420 * Announce informations for incoming router connection, but
1421 only after checking if it is replaced by backup router.
1422 Affected file silcd/packet_receive.c.
1424 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1426 * Fixed the backup resuming protocol to work in multiple
1427 router environment. Affected file silcd/server_backup.c.
1429 * Route packet only to one router in the function
1430 silc_server_packet_send_to_channel. Affected file is
1431 silcd/packet_send.c.
1433 * Fixed silc_server_send_notify_dest to set the broadcast
1434 flag. Fixed the silc_server_send_notify_topic to actually
1435 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1436 Affected file silcd/packet_send.c.
1438 * Changed the SFTP Filesystem interface. Changed the
1439 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1440 the filesystem operation function. The SilcSFTPFilesystem
1441 is now a context that is allocated by all filesystem allocation
1442 functions and it already includes the operations structure
1443 and filesystem specific context. It is given as argument
1444 now to the silc_sftp_server_start. This made the interface
1445 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1446 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1448 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1450 * Changed the backup router adding and getting interfaces
1451 in the server. The router that will be replaced by the
1452 specified backup router is now sent as argument. Affected
1453 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1456 * Added silc_net_addr2bin_ne to return the binary form of
1457 the IP address in network byte order. Affected files
1458 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1460 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1462 * Check for existing server ID in silc_server_new_server
1463 and in silc_server_connect_to_router_final and remove the
1464 old entry if it exists. Affected file silcd/packet_receive.c,
1467 * Send the channel message always to only one router, either
1468 in upstream or downstream. Affected file is
1469 silcd/packet_send.c.
1471 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1473 * Wrote the definition of the backup resuming protocol to the
1474 protocol specification.
1476 * Removed one redundant channel key generation from normal
1477 server during joining procedure. Removed one redundant
1478 channel key sending from server to router during joining
1479 procedure. Affected file silcd/command.c.
1481 * Made minor bugfixes to the backup router resuming protocol.
1482 Affected file silcd/server_backup.c, server.c.
1484 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1486 * Added --disable-asm configuration option. Affected files
1487 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1490 * Implemented the backup resuming protocol that is used to
1491 resume the primary router position in the cell after the
1492 primary router comes back online. Affected files
1493 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1494 and silcd/server_util.[ch].
1496 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1498 * Sleep two (2) seconds after sending QUIT command to server.
1499 Affected file lib/silcclient/command.c.
1501 * Assure that if outgoing data buffer is pending do not force
1502 send any data. Affected file silcd/packet_send.c.
1504 * Assure that if outgoing data buffer is pending do not force
1505 send any data. Affected file lib/silcclient/client.c.
1507 * Implemented the backup router support when the primary router
1508 goes down. The servers and routers can now use the backup
1509 router as new primary router without loosing connectivity.
1511 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1513 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1514 in the server to indicate disabled entry. All data read
1515 from the connection will be ignored and no data is sent
1516 for entry that is disabled. Affected files are
1517 silcd/idlist.h, silcd/server.c.
1519 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1521 * Created SFTP client and server test programs in the
1522 lib/silcsftp/tests directory.
1524 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1526 * Implemented memory filesystem (virtual filesystem) for
1527 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1530 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1532 * Implemented the SFTP (SSH File Transfer Protocol) to the
1533 lib/silcsftp. It includes SFTP client and SFTP server
1536 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1538 * Moved lib/silccore/silcprotocol.[ch] to the
1539 lib/silcutil library.
1541 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1542 take variable argument list pointer as argument. Affected
1543 file lib/silcutil/silcbuffmt.[ch].
1545 * Added silc_buffer_set function that is used to set data
1546 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1547 Affected file lib/silcutil/silcbuffer.h.
1549 * Changed various routines in the core library to use the new
1550 silc_buffer_set instead of allocating new buffer only for
1553 * Added 64-bit value formatting and unformatting support to the
1554 silc_buffer_[un]format routines. Affected file is
1555 lib/silcutil/silcbuffmt.[ch].
1557 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1558 to includes/bitmove.h.
1560 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1562 * Fixed channel user mode saving in client library. Affected
1563 file lib/silcclient/command[_reply].c.
1565 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Defined the file transfer to the SILC Protocol. Added
1568 new packet type SILC_PACKET_FTP and defined File Transfer
1569 Payload. The mandatory file transfer protocol is SFTP
1570 (SSH File Transfer Protocol). Affected file in addition
1571 of the internet draft is lib/silccore/silcpacket.h.
1573 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1574 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1575 is used as part of backup router protocol when the primary
1576 router of the cell is back online and wishes to resume
1577 the position as primary router.
1579 * Redefined the MAC generation keys in the protocol. The
1580 same key is not used anymore in both direction. Both
1581 direction will now use different keys for sending and
1582 receiving. This fixes a potential security flaw. This
1583 change causes incompatibilities in the protocol.
1585 * Redefined also the MAC computation from the packet.
1586 An packet sequence number is now added to the MAC
1587 computation. This prevents possible replay attacks against
1588 the protocol. This change too causes incompatibilities
1591 Added `sequence' field to the SilcPacketContext to hold
1592 the current sequence number for the packet.
1594 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1596 * Added `created' field to the SilcIDListData in the file
1597 silcd/idlist.h to indicate the time when the entry was
1600 * Added `created' field to the SilcChannelEntry too. Affected
1601 file silcd/idlist.h.
1603 * Added `creation_time' aguments to all the announcement functions
1604 in the server. If it is provided then only the entries that
1605 was created after the provided time frame are actually
1606 announced. Affected file silcd/server.[ch].
1608 * The protocol says that the Channel ID's IP address must be
1609 based on the router's IP address. Added check for this in
1610 the silc_server_new_channel when processing incoming New Channel
1611 Payload. Affected file silcd/packet_receive.c.
1613 * Print out the correct version with --version in SILC client.
1614 Affected file irssi/src/silc/core/silc-core.c.
1616 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1618 * Fixed WHOWAS command to check for completnes of the client
1619 entry always, not just when the command is coming from client.
1620 Affected file silcd/command.c.
1622 * Added new function silc_server_packet_queue_purge to purge the
1623 outgoing data queue to the network. After the function returns
1624 it is guaranteed that the outgoing packet queue is empty.
1625 Affected file silcd/packet_send.[ch].
1627 * Purge the outgoing packet queue in the rekey protocol's final
1628 callback to assure that all rekey packets go to the network
1629 before quitting the protocol. Affected file silcd/server.c.
1631 * Added silc_client_packet_queue_parse as similar function as
1632 in server to the client library. The affected file is
1633 lib/silcclient/client.c.
1635 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1637 * Splitted silcd/server.c and created silcd/server_util.[ch]
1638 for utility functions.
1640 * Added new socket flag SILC_SF_DISABLED to indicate that the
1641 connection is open but nothing can be sent to or received from
1642 the connection. Affected file lib/silcutil/silsockconn.[ch].
1643 The checking for disabled socket is checked in the low level
1644 silc_socket_write and silc_socket_read functions.
1646 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1648 * Allow only nicknames and channel names that fits into the
1649 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1651 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1653 * When processing JOIN command reply in server check that if
1654 the channel exists in our global list we'll move it the local
1655 list. Affected file silcd/command_reply.c.
1657 * Fixed the check whether client is joined on the channel already
1658 in JOIN command. Affected file lib/silcclient/command.c.
1660 * Fixed the JOIN command reply to check whether the channel
1661 already exists. Affected file lib/silcclient/command_reply.c.
1663 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1665 * Added silc_ske_status_string to map the SKE error numbers
1666 to readable strings. The affected files are
1667 lib/silcske/silcske[_status].[ch].
1669 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1671 * Do not show the private channels on the WHOIS channel list
1672 as it is not allowed by the protocol. The affected file is
1675 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1677 * Assure that the packet length digged from the actual packet
1678 is something sensible in the silc_packet_decrypt_rest_special
1679 in lib/silccrypt/silcpacket.c.
1681 * Free and NULL the allocated pointer in silc_hmac_alloc if
1682 the HMAC allocation fails. The affected file is
1683 lib/silccrypt/silchmac.c.
1685 * Print the selected security properties to the log files in
1686 the server. Affected file silcd/protocol.c.
1688 * Add SKE's reference counter even if calling the completion
1689 callback manually. Otherwise it goes negative, although it
1690 does not cause any problems. The affected file is
1691 lib/silcske/silcske.c.
1693 * Remove the client entry with short timeout after giving the
1694 KILL command. Affected file lib/silcclient/command.c.
1696 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1697 case all found clients are already disconnected (WHOWAS would
1698 found them) in the server. Affected file silcd/command.c.
1700 * Update the last_receive (time of last data received) to be
1701 updated only when received private or channel message so that
1702 the idle time showed in WHOIS makes more sense.
1704 * Added boolean field `valid' in to the SilcClientEntry in the
1705 client library to indicate whether the entry is valid or not.
1706 This fixes the nickname change bug on channel when changing
1707 the nickname to be same than the old (like nick to Nick) the
1708 nickname formatter doesn't set the new nick anymore to Nick@host.
1709 Affected file lib/silcclient/idlist.[ch].
1711 * Now actually fixed the nickname changing on disconnection.
1712 Added new function silc_change_nick to the Irssi SILC Client.
1713 Affected file irssi/src/silc/core/client_ops.c,
1714 irssi/src/silc/core/silc-nicklist.[ch].
1716 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1718 * Check that the public key exists in the GETKEY command before
1719 trying to encode it. Affected file silcd/command.c.
1721 * Print some notifications on received public keys with GETKEY
1722 command in the Irssi SILC Client. Affected files are
1723 irssi/src/fe-common/silc/module-formats.[ch],
1724 irssi/src/silc/core/client_ops.c.
1726 * Use IDENTIFY command to resolve the server information in the
1727 GETKEY command instead of INFO command. Affected file
1728 lib/silcclient/command.c.
1730 * All command reply functions in the client library now calls
1731 the pending command reply callbacks even if an error has
1732 occurred. The server has done this a long time and now it was
1733 time to move the client library to this as well. Now all
1734 errors can be delivered back to the pending command reply
1735 callbacks if necessary. Affected files are
1736 lib/silcclient/command[_reply].[ch].
1738 * Change the nickname on disconnection back to the username
1739 because in reconnect the server will enforce it to it anyway.
1740 Affected file irssi/src/silc/core/silc-servers.c.
1742 * Fixed a config file parsing bug in the Irssi SILC client.
1743 Affected file irssi/src/silc/core/clientconfig.c.
1745 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1747 * When printing the channel mode on JOIN, verify that the
1748 channel key and channel's HMAC are valid. Affected file
1749 irssi/src/silc/core/client_ops.c.
1751 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1753 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1754 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1755 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1757 * Removed channel key rekey task deleting from the function
1758 silc_server_save_channel_key. Affected file silcd/server.c.
1759 Added explicit timeout task context instead that is used to
1760 delete the task if we are registering a new task before the
1761 new task has elapsed.
1763 * When channel key rekey occurs the client library now saves
1764 the old channel key for a short period of time (10 seconds) and
1765 is able to use it in case some is still sending channel
1766 messages encrypted with the old key after the rekey. Affected
1767 file lib/silcclient/[idlist.h|client_channel.c].
1769 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1771 * Added check to the silc_server_new_id_real to not accept
1772 new ID if it is the sender's own ID. Affected file is
1773 silcd/packet_receive.c.
1775 * Assure that we do not announce ourself or the one we've
1776 sending our announcements when we're router and are announcing
1777 servers to our primary router. Affected file silcd/server.c.
1779 * Fixed silc_server_command_identify_check_client to assemble
1780 correct WHOIS packet. It send corrupted WHOIS packet and
1781 caused problem with router to router connections. Affected
1782 file silcd/command.c.
1784 Fixed also silc_server_command_whois_check the same way
1785 as for the IDENTIFY command.
1787 * Added new SilcIDListStatus to the server in the SilcIDListData
1788 structure. The status now includes the current status of
1789 the entry (like registered, resolved etc.). Affected file
1790 silcd/idlist.[ch]. Defined a bunch of different status types
1791 as well. This replaced the old boolean registered field as well.
1793 Added resolve_cmd_ident field to the SilcClientEntry structure
1794 too so that if the entry is for example being resolved so
1795 another command may attach to the same pending command reply
1796 without requiring to resolve the same entry again. This concept
1797 should optimize the WHOIS and the IDENTIFY resolving under
1798 heavy load by taking away unnecessary resolving for entries
1799 that are being resolved already.
1801 Added support for adding multiple pending commands for one
1802 command idenfier. Affected file silcd/command[_reply].[ch].
1804 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1805 before deleting the data. Otherwise the hash table will have
1806 freed data in comparison functions. Affected file is
1807 silcd/command_reply.c.
1809 * Fixed silc_idlist_replace_client_id to add the new entry to
1810 the cache with NULL nickname. Otherwise there will be invalid
1811 memory as the nickname after the nickname is freed. Affected
1812 file silcd/packet_receive.c.
1814 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1815 saved into wrong slots because the previous number of entries
1816 was not taken into account. Affected file silcd/idlist.c.
1817 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1819 * If we are router and we receive JOIN notify to a channel that
1820 does not have any users then notified client is marked as the
1821 channel founder, as it is it. The affected file is
1822 silcd/packet_receive.c
1824 * Added to the extended hash table API's table_del_*ext functions
1825 the destructor as argument too, so that the caller can decide
1826 which destructor to use or whether to use destructor at all.
1827 Affected file lib/silcutil/silchashtable.[ch].
1829 * Fixed ID Cache purging. It actually deleted the entries from
1830 the hash table after the data was freed. The hash table ended
1831 up comparing freed memory. The affected file is
1832 lib/silccore/silcidcache.c.
1834 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1836 * Fixed Irssi SILC client's KILL command's HELP syntax.
1838 * The USERS command now resolves the detailed user information
1839 if the userinfo field is missing. Affected file is
1840 lib/silcclient/command_reply.c.
1842 * Do not print error in silc_file_read if the read file does
1843 not exist. Just silently return NULL. Affected file is
1844 lib/silcutil/silcutil.c.
1846 * Fixed the silc_log_output to not wine about NULL filename
1847 and to not create some bogus " " filename. Affected file is
1848 lib/silcutil/silclog.c.
1850 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1852 * Fixed various printing bugs on the user interface in the
1853 Irssi SILC Client. Minor changes that were forgotten from
1856 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1858 * Fixed the configure.in.pre and the compilation and distribution
1859 environment to support the new autoconf 2.52. That version is
1860 now required to compile the CVS trunk.
1862 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1864 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1865 to generally parse user@fqdn format strings. Affected file
1866 lib/silcutil/silcutil.c.
1868 * Added nickname_format and nickname_force_format fields to the
1869 SilcClientParams structure. The first one defines the format
1870 for the nicknames that the library will enforce if the receives
1871 multiple same nicknames. The second one is boolean value and
1872 can be used to force the library to always enforce the format
1873 to the nicknames regardles whether there are multiple nicknames
1874 or not. This configurable formatting was employed to flexibly
1875 support accessing multiple nicknames from the user interface.
1876 The userinterface can now set the nicknames to what ever format
1877 they prefer. Affected file lib/silcclient/silcapi.h.
1879 Added function silc_client_nickname_format to the file
1880 lib/silcclient/idlist.c. It performs the nickname formatting.
1882 Added new field `hostname´ to the SilcClientEntry context.
1883 It holds the hostname of the client. Affected file is
1884 lib/silcclient/idlist.h.
1886 * Irssi SILC Client sets the nicknames in nick@hostn format.
1887 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1888 irssi/src/silc/core/silc-core.c.
1890 The WHOIS printing now also shows both the real nickname and
1891 the formatted nickname so that user knows how to access the
1892 user if there are multiple same nicknames cached. Affected
1893 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1894 printing formatting too to take the hostname now as a separate
1895 argument. The Affected file is
1896 irssi/src/fe-common/silc/modules-formats.[ch].
1898 * Changed the silc_client_get_clients_local to accept the formatted
1899 nickname as argument. It accepts the real nickname too but the
1900 formatted nickname can be used to find the true entry from
1901 multiple entries. Affected file lib/silcclient/silcapi.h and
1902 lib/silcclient/idlist.c.
1904 * Added nickname_format_parse field to the SilcClientParams.
1905 It is a callback function provided by the application to parse
1906 the nickname out of the formatted nickname string. The library
1907 calls it to get the nickname from the formatted string. Since
1908 the application generally knows better the format of the nickname
1909 string it parses it instead of the library, even though library
1910 encodes the formatted string. If the callback function is not
1911 provided then the library will use the string as is. The
1912 affected file is lib/silcclient/silcapi.h.
1914 * All the nickname strings passed to the client library in
1915 commands are now expected to be formatted nickname strings.
1916 If the command does not support the formatted nickname string
1917 it will assume that the sent string is the actual nickname.
1918 Affected file lib/silcclient/command.c.
1920 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1922 * Added public key authentication support to OPER and SILCOPER
1923 commands in the client library. Affected file is
1924 lib/silcclient/command.c.
1926 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1928 * Changed the get_auth_methdod client operation to be asynchronous.
1929 It can be async if the application resolves the authentication
1930 method from the server during the negotiation. Added new
1931 SilcGetAuthMeth completion callback that the application will
1932 call after resolving the authentication method.
1934 Added function silc_client_request_authentication_method that
1935 the application can use to resolve the authentication method
1936 from the server. Added also SilcConnectionAuthRequest callback
1937 that the library will call after the server has replied. The
1938 application can call this function if it does not know the
1939 current authentication method.
1941 Affected files are lib/silcclient/client.c and
1942 lib/silcclient/silcapi.h.
1944 * The Irssi SILC client now automatically resolves the authentication
1945 method incase any configuration information is not present (and
1946 currently there never is). The affected file is
1947 irssi/src/silc/core/client_ops.c.
1949 * Fixed public key authentication from the client library.
1950 Affected file lib/silcclient/protocol.c. Changed also the
1951 protocol specification about the public key authentication in
1952 the connection authentication protocol. The actual data to be
1953 signed is now computed with a hash function before signing.
1955 * Fixed the public key authentication from the server as well.
1956 Affected file silcd/protocol.c.
1958 * Removed the mlock()'s from the memory allocation routines.
1959 Affected file lib/silcutil/silcmemory.c. The ./configure does
1960 not check anymore for the mlock(). Affected file is
1963 * Fixed USERS command in server to allow the execution of the
1964 command for private and secret channels if the client sending
1965 the command is on the channel. Affected file silcd/command.c.
1967 * Fixed silc_client_get_clients_local to return the clients
1968 count correctly. It could return wrong value. Affected file
1969 lib/silcclient/idlist.c.
1971 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1974 types. The assembler optimizations seemed not to like 64-bit
1975 data types. The assmebler optimizations thus are now enabled
1976 also for BSD systems as opposed to only enable them for Linux.
1978 * Do not check for threads at all on BSD systems. Affected
1979 file configure.in.pre.
1981 * Removed -n and -h options from the Irssi SILC Client since
1982 they are not used in silc.
1984 * Fixed the prime generation to assure that the first digit
1985 of the generated random number is not zero since our conversion
1986 routines does not like number strings that starts with zero
1987 digit. If zero digit is seen the random number is regenerated.
1988 This caused some corrupted RSA keys when the zero first digit
1989 was met. Affected file lib/silcmath/silcprimegen.c.
1991 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1993 * Fixed WIN32 configuration in the ./configure script.
1994 Fixed to include xti.h on environments that has it.
1995 Patches by Carsten Ilchmann and andrew.
1997 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1999 * Changed the silc_id_create_client_id to be collision
2000 resistant. It is now assured that there cannot be created
2001 two same client ID's. I suspect that some weird bugs in
2002 the server were actually caused by duplicate Client IDs.
2003 Affected file silcd/serverid.[ch]. A router receiving
2004 new ID now also assures and informs the sending server
2005 if the ID caused collision.
2007 * Changed the silc_id_create_channel_id to also assure that
2008 there are no collisions.
2010 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2012 * Statement about ignoring the Mutual Authentication flag when
2013 performing rekey with PFS was a bit misleading. It is ignored
2014 if it was set in the initial negotiation, it cannot be even
2015 set in the rekey. Fixed in the ke-auth draft. Started the
2016 new versions of the protocol drafts in the doc/.
2018 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2020 * Fixed a bug in silc_client_command_identify_save when saving
2021 new channel information. The channel name was no duplicated
2022 and caused crash on exit. Affected file is
2023 lib/silcclient/command_reply.c.
2025 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2027 * Fixed the getkey command handling in the server. Send just
2028 empty OK reply to the sender if the key could not be fetched
2029 (but everything else was ok, like the key just was not available).
2030 Changed the public key parameter to optional in the protocol
2031 specs so that empty OK reply can be sent. Affected file
2034 Added a message to Irssi SILC client to tell to user if the
2035 server did not return a public key.
2037 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2039 * Fixed a channel key regeneration bug. It registered new
2040 timeout tasks exponentially until all system resources were
2041 used. Affected file silcd/server.c.
2043 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2045 * Added the SILC Document generator to the scripts/silcdoc.
2046 It can be used to generate the Toolkit Reference Manual out
2047 of the source tree. Internally it will also use the RoboDoc
2048 generator now imported in util/robodoc.
2050 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2052 * Added couple of return's in rekey protocol if error orccurred
2053 during the protocol. The execution must be terminated.
2054 Affected file silcd/protocol.c. Also, terminate the protocol
2055 always with timeout.
2057 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2059 * The client's Client ID was created initally from the wrong
2060 nickname (it could have been in format nick@host) in the
2061 silc_server_new_client. Affected file silcd/packet_receive.c
2063 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2065 * Added some SILC_LOG_ERROR's to various error conditions
2066 if client could not be added to ID cache. Affected files
2067 silcd/packet_receive.c and silcd/server.c.
2069 * When client's sock->user_data is freed, NULL also the
2070 client->router and client->connection pointers. Added check
2071 for these pointers being NULL to various places around the
2072 code. Affected file silcd/server.c.
2074 * Added client->data.registered == TRUE checks to various
2075 places around the code to assure that unregistered client's
2076 are not handled when it is not allowed. Affected file
2079 * Added `bool registered' fields to all
2080 silc_idlist_[server|client]_get_* routines to indicate whether
2081 the fetched client needs to be registered or not. Affected
2082 file silcd/idlist.[ch].
2084 * Add your own entry as registered to the ID cache in the
2085 server. Affected file server.c.
2087 * Fixed a bug in silc_server_new_server. The SilcServer was
2088 set as the new server's context instead of SilcServerEntry.
2089 This naturally caused some weird bugs.
2091 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2093 * Do not delete the channel rekey task when adding it
2094 for in silc_server_create_channel_key.
2096 * Changed the silc_server_create_channel_key to return
2097 TRUE or FALSE to indicate the success of the channel key
2100 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2102 * Fixed MSVC++ project files and added missing files to
2103 Makefiles under win32/.
2105 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2107 * Do not add TCP_NODELAY flag if the operating system
2108 does not have it defined. Affected files are
2109 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2111 * Fixed buffer overflow from Irssi SILC Client. Affected
2112 file irssi/src/fe-common/core/themes.c.
2114 * Fixed double free in client library in the file
2115 lib/silcclient/client.c when disconnecting from server.
2117 * Applied double free patch from cras to Irssi SILC client.
2118 Affected files irssi/src/core/[modules/expandos].c
2120 * Fixed the disconnection handling to Irssi SILC Client.
2121 The application must call silc_client_close_connection
2122 in ops->connect client operation in case of failure of
2123 the connection. Affected file is
2124 irssi/src/silc/core/client_ops.c.
2126 * Do not set sock->protocol to NULL in the function
2127 silc_client_close_connection after executing the protocol's
2128 final callback since the sock might not be valid anymore.
2129 Affected file lib/silcclient/client.c.
2131 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2133 * Do not enable SILC_THREADS if the linking with libpthread
2134 did not happen. Affected file configure.in.pre.
2136 * Added notion to protocol specification that server must
2137 verify the sent authentication payload with CMODE when
2138 setting the channel founder key. Implemented it to the
2139 server. Affected file silcd/command.c.
2141 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2143 * Added _EXTRA_DIST SILC distribution variable to the
2144 distributions file. It is used to conditionally add extra
2145 files or directories to the specific distribution. Affected
2146 files ./prepare, Makefile.am.pre and distributions.
2148 Removed the `_' from the start of the distribution names.
2151 * Added README.WIN32 for instructions to compile the Toolkit
2154 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2156 * Fixed a double free in disconnection in the server. Affected
2157 file is silcd/server.c.
2159 * Fixed the lib/silcske/groups.c to work now also with GMP
2160 MP library. The string conversion did not work when using
2161 specific base and the base is indicated in the string as well.
2163 * Created win32/ directory which now includes MSVC++ specific
2164 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2165 It will appear only in the toolkit distribution
2167 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2169 * Changed the key material distribution function in case when
2170 the hash output is too short. The data is now concatenated
2171 a bit differently than it used to. Made the change to the
2172 SKE protocol specification.
2174 * Added better GMP detection to configure.in.pre. A patch
2177 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2179 * Fixed a minor bug in SKE that might cause some problem on
2180 some platforms. Affected file lib/silcske/silcske.c.
2182 * Added the cookie checking for initiator in the SKE. It checks
2183 that the responder returns the sent cookie unmodified. The
2184 affected file is lib/silcske/silcske.c. Added new SKE
2185 error type INVALID_COOKIE that can be sent during the
2186 negotiation. Fixed some memory leaks as well.
2188 * Added the "invalid cookie" error message to Irssi SILC client's
2191 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2193 * Added `task_max' field to the SilcClientParams to indicate
2194 the maximum tasks the scheduler can handle. If set to zero,
2195 default values are used. Affected file lib/silcclient/silcapi.h.
2197 * Fixed memory leaks in silc_client_close_connection. Affected
2198 file lib/silcclient/client.c.
2200 * Added silc_client_del_client_entry to client library to free
2201 all memory of given client entry. Affected file is
2202 lib/silcclient/idlist.[ch].
2204 * Added new functions silc_client_del_channel and
2205 silc_client_del_server to delete channel and server entries.
2206 Affected file lib/silcclient/[silcapi.h/idlist.c].
2208 * Removed silc_client_del_client_by_id from silcapi.h.
2210 * Fixed the INFO command to return the server's own info
2211 correctly when querying by Server ID. Affected file is
2214 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2216 * Removed the non-blocking settings in WIN32 code in the
2217 silc_sock_[read/write] and added SleepEx instead. Affected
2218 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2219 of input data is now checked with FIONREAD and ioctlsocket.
2221 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2223 * Call silc_schedule_task_del_by_context in the
2224 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2225 Affected file lib/silccore/silcprotocol.c.
2227 * Call silc_protocol_cancel for active protocols in the
2228 silc_server_close_connection if the funtion
2229 silc_server_free_sock_user_data has not been called.
2230 Affected file silcd/server.c.
2232 * Generic tasks cannot be deleted using the del_by_fd
2233 task deleting function since generic tasks does not match
2234 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2236 * Added a notion to SILCOPER help file that the SILCOPER works
2237 only on router server, not on normal server.
2239 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2241 * Added for WIN32 support for the new scheduler as well.
2242 Affected file lib/silcutil/win32/silcwin32schedule.c.
2244 * Fixed the SHA1 implementation to work on various platforms.
2246 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2248 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2249 API. It is part of the scheduler now. Everything else is
2250 as previously but some functions has changed their names.
2251 Checkout the lib/silcutil/silcschedule.h for the interface.
2252 Updated all applications to use the new interface. Affected
2253 files are lib/silcutil/silcschedule.[ch].
2255 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2257 * Found a bug in the SKE implementation. The HASH value,
2258 specified by the protocol, was not computed correctly. The
2259 public key of the responder was not added to the computation
2260 even though it is mandatory. Affected file lib/silcske/silcske.c.
2261 This unfortunately causes incompatibilities with older
2262 clients and servers.
2264 * Added WIN32 specific network init and uninit functions:
2265 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2266 the Winsock2. Affected file lib/silcutil/silcnet.h and
2267 lib/silcutil/win32/silcwin32net.c.
2269 * Set the socket always to nonblocking mode on WIN32 after
2270 reading data or writing data. Affected file is
2271 lib/silcutil/win32/silcwin32sockconn.c.
2273 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2275 * Fixed various compilation problems under WIN32. Affected
2276 files lib/silcutil/win32/silcwin32thread.c and
2277 lib/silcutil/win32/silcwin32schedule.c.
2279 * Removed all _internal.h #includes from public header
2280 files. Internal headers must never be included from
2283 Removed also the lib/silcske/payload_internal.h file.
2285 * All include files that may be needed (public and some others
2286 included by the public headers) by application developers are
2287 now copied to the ./includes directory. It does not copy any
2288 internal headers. Affected file Makefile.defines.pre and all
2289 Makefile.am's under lib/ and subdirs.
2291 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2293 * Do not change the ~/.silc directory's permissions automatically.
2294 Affected file irssi/src/silc/core/clientutil.c.
2296 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2298 * Do not cancel the protocol in silc_server_close_connection
2299 it might cause recursion. Now cancelled in the function
2300 silc_server_free_sock_user_data. Affected file silcd/server.c.
2302 * Fixed the silc_server_remove_clients_by_server to regenerate
2303 the channel keys correctly finally. Added also new function
2304 silc_server_remove_clients_channels to actually do it.
2305 Affected file silcd/server.c.
2307 * Fixed the silc_server_new_channel to not crash by giving
2308 wrong router to the new channel. Affected file is
2309 silcd/packet_receive.c.
2311 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2313 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2314 which is given as argument to the silc_client_alloc now.
2315 It can be used to configure the client and set various parameters
2316 that affect the function of the client.
2318 * The USERS command in server did not check whether the channel
2319 is private or secret. Affected file silcd/command.c.
2321 * Added new argument to the USERS command in protocol specification.
2322 The USERS command now can take the channel name as argument
2323 as well. Added support for this in client and server and
2324 updated the protocol specs.
2326 * Completed the GETKEY command in client. It can be now used
2327 to fetch also servers public key not only some clients.
2328 Affected files lib/silcclient/command[_reply].c.
2330 * Added silc_client_get_server to return server entry by the
2331 server name. Affected files lib/silcclient/silcapi.h and
2334 * Redefined the IDENTIFY command in protocol specification to be
2335 more generic. It now can be used to query information about
2336 any entity in the SILC Network, including clients, servers and
2337 channels. The query may be based either the entity's name
2338 or the ID. Added support for this in both client and server.
2340 Affected files silcd/command.c and lib/silcclient/command.c
2341 and command_reply.c.
2343 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2344 the _from_client and _from_server functions. Affected file
2347 * Added silc_client_get_channel_by_id_resolve to the file
2348 lib/silcclient/silcapi.h to resolve channel information by
2349 its ID. Added also silc_client_get_channel_by_id that
2350 does not resolve it from the server.
2352 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2354 * Added SilcServerEntry context into the client library
2355 to represent one server. The INFO command now allocates
2356 these to save the resolved server info. For now on the
2357 client library will also keep information about servers,
2358 connected and resolved with INFO.
2360 The INFO command now allocates the SilcServerEntry context
2361 and saves the server info there. The COMMAND_REPLY in
2362 the INFO now returns the parameters to application in
2363 same order as defined in the protocol specification.
2365 The entries are cached in the client->server_cache.
2367 * The INFO command is now issued after received the Client ID
2368 from the server. Affected file lib/silcclient/client.c.
2370 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2371 to the application as the mode changer might be server.
2372 It is guaranteed that NULL is not returned anymore to the
2373 application. Affected file lib/silcclient/client_notify.c.
2375 The ID Type is now also passed to the application so that
2376 it can check whether the returned entry is SilcClientEntry
2379 Added new function silc_client_get_server_by_id to return
2380 the server entry by ID. Affected files are the
2381 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2383 * Do not create the channel in the Irssi SILC Client when issuing
2384 the JOIN command but when received the sucessful JOIN command
2385 reply. Otherwise the channel might get created even though we
2386 could not join it. The Affected file is
2387 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2389 * Fixed a channel joining bug in router. The router must also
2390 check the channel modes, invite and ban lists etc. when serving
2391 the JOIN command sent by normal server. Affected file is
2392 silcd/command.c. The router now resolves the client's
2393 information from the server who sent the JOIN command if it
2394 does not know it, and processes the JOIN command only after
2397 * Changed the SilcCommandCb to take new argument; void *context2.
2398 Affected file lib/silccore/silccommand.h
2400 The second argument in the command callbacks in the server now
2401 includes the SilcServerCommandReplyContext if the command was
2402 called as pending command callback from the command reply.
2403 Otherwise it is NULL. When called as pending the status of the
2404 command reply will be checked and if it was erronous the
2405 error will be sent to the original sender of the command.
2406 This way the client always receives the error messages even
2407 though the server was actually the one who received the error
2408 when it resent the command to router, for example. Affected
2409 files silcd/command[_reply].[ch].
2411 * Fixed sending WHOWAS command's error message to client if
2412 the requested client could not be found. It was missing.
2415 * Changed the CMODE and CUMODE commands reply arguments in the
2416 protocol specification. The Channel ID is now sent in both
2417 of the commands to identify the channel. Implemented this
2418 new feature to the client and server. Affected files
2419 lib/silcclient/command_reply.c and silcd/command.c.
2421 * Made better checks for invite and ban lists in the JOIN
2422 command in server. Affected file silcd/command.c.
2424 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2426 * The server now performs the incoming host IP/DNS lookup
2427 using the silc_socket_host_lookup and thus does not block
2428 the server anymore. Affected file silcd/server.c.
2430 * Completed the multi-thread support for SILC Scheduler in
2431 the lib/silcutil/silcschedule.c.
2433 * Fixed the configure.in.pre to detect the pthread correctly
2436 * Fixed a deadlock in silc_task_queue_wakeup in the file
2437 lib/silcutil/silctask.c.
2439 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2441 * Added new function silc_schedule_wakeup that is used in
2442 multi-threaded environment to wakeup the main thread's
2443 schduler. It needs to be used when a thread adds a new task
2444 or removes a task from task queues. After waking up, the
2445 scheduler will detect the task queue changes. If threads
2446 support is not compiled in this function has no effect.
2447 Implemented the wakeup mechanism to both Unix and WIN32
2448 systems. Affected files are lib/silcutil/silcschedule.[ch],
2449 lib/silcutil/unix/silcunixschedule.c and the
2450 lib/silcutil/win32/silcwin32schedule.c.
2452 * Added new function silc_task_queue_wakeup to wakeup the
2453 scheduler by the specified task queue. Affected file
2454 lib/silcutil/silctask.[ch].
2456 * The silc_socket_host_lookup_start now wakes up the scheduler
2457 after adding the timeout task. Affected file is
2458 lib/silcutil/silcsockconn.c.
2460 * The silc_socket_host_lookup is synchronous now if the threads
2461 support is not compiled in. However, the callback is still
2462 called asyncronously through the scheduler, anyway. Affected
2463 file lib/silcutil/silcsockconn.c.
2465 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2467 * Added new function silc_socket_host_lookup to perform
2468 asynchronous IP and FQDN lookups for the socket connection.
2469 Affected files lib/silcutil/silcsockconn.[ch].
2471 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2473 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2474 that may or may not compile the mutex support in.
2476 Changed the silc_mutex_alloc interface. It allocates the
2477 mutex now to the sent pointer and returns TRUE or FALSE.
2479 Affected file lib/silcutil/silcmutex.h.
2481 * Wrote the SILC Task Queue interface to support multi-threads.
2482 Affected file lib/silcutil/silctask.[ch].
2484 * Wrote the SILC Scheduler to support multi-threads. Affected
2485 file lib/silcutil/silcschedule.c.
2487 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2489 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2490 in lib/silcutil/win32/.
2492 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2494 * Defined SILC Mutex API and SILC Thread API and implemented
2495 them for Unix. Affected files are
2496 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2497 lib/silcutil/unix/silcunixmutex.c and
2498 lib/silcutil/unix/silcunixthread.c.
2500 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2502 * Fixed the silc_server_remove_clients_by_server's channel
2503 key re-generation. The hash table handling was incorrect
2504 and would not work with many channels. Affected file is
2507 * Fixed some memory leaks around the server code.
2509 * Rewrote the silc_server_get_users_on_channel to support IPv6
2510 based Client ID's. Affected file silcd/server.c.
2512 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2513 specification. However, a separate document must be written
2514 to define the detailed signing procedure and the payload
2515 associated with the flag. Defined the flag to the
2516 lib/silccore/silcchannel.h as well.
2518 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2520 * Changed the dynamic tables to static size tables in the
2521 lib/silccrypt/silchmac.c.
2523 * Removed GCC dependencies from the code. A patch by cras.
2525 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2527 * Do not show the error "Error receiving packet bla bla"
2528 in server if it really was not an error (-2 means that reading
2529 is pending). Affected file silcd/server.c.
2531 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2533 * Fixed a possible crash in silc_server_remove_clients_by_server
2534 in silcd/server.c. Fixed there also some memory leaks.
2536 * Fixed the silc_idlist_replace_client_id. It could replace
2537 wrong key in the hash table. Affected file silcd/idlist.c.
2539 * Do not check whether there are global users on the channel
2540 if the channel->global_users is FALSE. Affected functions
2541 silc_server_remove_from_one_channel and
2542 silc_server_remove_from_channels in silcd/server.c. Also,
2543 do not check if the removed client is local as we can be
2544 sure that global client was not removed from the channel
2545 and checking for global users is not needed.
2547 * The silc_server_remove_clients_by_server now re-generates
2548 the channel keys correctly for those channels that had
2549 clients removed from them. Affected file silcd/server.c.
2551 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2553 * Found the reason of random crashes in the server. We weren't
2554 ignoring the SIGPIPE signal (which can be sent in write())
2555 and it crashed the server. Affected file silcd/silcd.c.
2557 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2559 * Assure that sock->user_data is not NULL in the function
2560 silc_server_packet_send in silcd/packet_send.c.
2562 * Disconnect the remote connection if it could not be added
2563 to any ID lists in the server. The affected file is
2566 * Check in silc_server_packet_send[_real/dest] that the
2567 socket is not disconnecting and ignore the data if it is.
2568 Affected file silcd/packet_send.c.
2570 * Define inline to __inline on native WIN32 compilation.
2571 Affected file includes/silcwin32.h.
2573 * Added some explicit type casts for inline code since MSVC
2574 require them. Affected files lib/silcutil/silcbuffer.h,
2575 lib/trq/silcdlist.h and lib/trq/silclist.h.
2577 * Print warning in log files from now on if the packet
2578 decryption fails. Affected file silcd/server.c.
2580 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2582 * Changed the `say' client operation's interface to accept
2583 new `type' argument to indicate the type of the message sent
2584 by the library. The application may filter the library's
2585 messages according the type. The affected file is the
2586 lib/silcclient/silcapi.h.
2588 * Added two new functions to lib/silcclient/silcapi.h:
2589 silc_client_del_client and silc_client_del_client_by_id.
2590 Affected file lib/silcclient/idlist.c.
2592 * Moved the clientincludes.h from includes/ to silc/ and
2593 serverincludes.h from includes/ to silcd/.
2595 * The modes for the CMODE and CUMODE are now passed as
2596 uint32 for application with COMMAND_REPLY. The affected
2597 file is lib/silcclient/command_reply.c.
2599 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * /WHOIS without arguments shows client's own information.
2602 Affected file lib/silcclient/command.c.
2604 * Changed PING to not accept any arguments. The specs
2605 says that client can ping only the connected server so
2606 requiring an argument is not needed. Affected file is
2607 lib/silcclient/command.c.
2609 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Fixed a fatal bug in private message sending and reception
2612 encryption and decryption when using private message keys.
2613 The implementation was incorrect and did not follow the
2614 specification. It causd that some of the message were
2615 lost since it did not use the sending and receiving keys
2616 as the protocol suggests. This has been fixed and will cause
2617 incompatibilities with older clients when sending private
2618 message encrypted with private message keys. Affected files
2619 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2620 and various other in Irssi SILC Client.
2622 Added `responder' boolean argument to the functions
2623 silc_client_add_private_message_key[_ske] to indicate when
2624 the key is added as responder or initiator of the key
2627 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2629 * Removed the silc_ske_check_version function and created
2630 a SilcSKECheckVersion callback. Added also a function
2631 silc_ske_set_callbacks that is now used to set all SKE
2632 callbacks. The callback functions are not given to
2633 the SKE functions anymore, but this function is used to
2636 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2638 * Added `silc_version' argument to the silc_client_alloc
2639 to define the version of the application for the library.
2640 The library will use the version string to compare it
2641 against the remote host's (usually a server) version
2642 string. Affected file lib/silcclient/silcapi.h
2644 * Added the KE protocol context to Key Agreement context
2645 in client library so that we can abort the SKE if it
2646 is in process when we get timeout. Affected file is
2647 lib/silcclient/client_keyagr.c.
2649 * Do not resolve the client ID forever if it returns in the
2650 first time that such client does not exist. This was done
2651 for example with private message. Affected file is
2652 lib/silcclient/client_prvmsg.c.
2654 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2656 * Do not add regex.h for WIN32. The affected file
2657 includes/silcincludes.h.
2659 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2660 not work yet 100%. It generates the DLL's automatically
2661 when compiling with --with-win32 under cygwin.
2663 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2665 * lib/contrib/regex.c is not compiled on WIN32.
2667 * Added silc_net_get_socket_opt function to the
2668 lib/silcutil/silcnet.h.
2670 * Added includes/silcwin32.h for WIN32 specific includes
2673 * Do not use ptime structure or any of the posix process
2674 functions on WIN32 in lib/silccrypt/silrng.c.
2676 * Added silc_gettimeofday to provide generic function
2677 for struct timeval on all platforms. Added the function
2678 to lib/silcutil/silcutil.h.
2680 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2682 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2683 library as they clearly belong there. As a plus side we
2684 can make the actual socket connection routines platform
2687 Added also new generic function silc_socket_read and
2688 silc_socket_write (that used to be silc_packet_[read/write].
2689 The implementation of these are platform specific.
2691 * Added WIN32 specific routines of silc_socket_[read/write]
2692 to lib/silcutil/win32/silcwin32sockconn.c.
2694 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2696 * Added preliminary support for native WIN32 compilation under
2697 cygwin (using the -mno-cygwin option for GCC) to the
2698 ./configure.in.pre. The --with-win32 now prepares the
2699 compilation for native WIN32.
2701 * Rewrote the SILC Scheduler interface in the file
2702 lib/silcutil/silcschedule.h. The scheduler is now context
2703 based and does not have anymore any global static scheduler.
2704 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2705 and created lib/silcutil/win32 directory for WIN32 based
2708 * Added Unix specific network routines to the
2709 lib/silcutil/unix/silcunixnet.c and the old
2710 lib/silcutil/silcnet.c includes now only generic routines.
2712 Added WIN32 specific network routines to the
2713 lib/silcutil/win32/silcwin32net.c.
2715 * Added Unix specific utility functions from the
2716 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2718 * Added WIN32 SILC Scheduler to the file
2719 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2722 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2724 * Do not handle JOIN notify in the server if the target client
2725 is not registered (idata->registered == FALSE). The affected
2726 file is silcd/packet_receive.c.
2728 * Update the nickrec->founder in event_cumode in the Irssi SILC
2729 client. Affected file irssi/src/silc/core/silc-channels.c.
2731 * Fixed the CUMODE_CHANGE notify handling in the server when
2732 server and router are announcing their clients on channels.
2733 Now the mode changes are saved and notified correctly. The
2734 affected file is /silcd/packet_receive.c.
2736 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2737 They really did not replace the cache entry in the ID Cache.
2738 Now they do that. Affected file silcd/idlist.c.
2740 * Fixed the KICK notify handling in the Irssi SILC client to
2741 update the channel records so that the kicked client does not
2742 appear to be on the channel. The affected file is
2743 irssi/src/silc/core/silc-channels.c.
2745 * Always update the conn->current_channel when executing command
2746 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2748 * Fixed the KILL notify handling in Irssi SILC client to remove
2749 the killed client on all channels.
2751 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2753 * Fixed the silc_parse_command_line to remove extra spaces
2754 from the start and end of the arguments. Affected file is
2755 lib/silcutil/silcutil.c.
2757 * Cancel and free any active protocol in the function
2758 silc_server_close_connection. Affected file silcd/server.c.
2760 * Cancel and free any active protocol in the function
2761 silc_client_close_connction. Affected file is
2762 lib/silcclient/client.c.
2764 * Do not execute the KILL command for clients that are in
2765 history (ie. they are not in the network). Affected file is
2768 * Fixed KILL notify handling, client does not crash anymore.
2769 Affected file irssi/src/silc/core/silc-channels.c.
2771 * Reduced the default packet buffer size from 2048 to 1024 in
2772 lib/silccore/silcpacket.c.
2774 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2775 counter to the SKE context that is incresed when the SKE library
2776 performs async operation outside the library. If the outside
2777 process frees the SKE context and FREED status will be set
2778 and the library will detect after the sync operation that the
2779 libary is freed. The affected files are
2780 lib/silcske/silcske[_status].[ch].
2782 * Resolve the client entry information in the function
2783 silc_client_channel_message to assure that NULL pointer is not
2784 passed as client entry to the application. */
2786 * Fixed the task timeout calculation to assure that there is
2787 never negative timeouts. The affected file is
2788 lib/silcutil/silcschedule.c.
2790 * Fixed the channel user mode notification sending in server.
2791 It was sent point-to-point to the router (or to server by router)
2792 but it needs to be destined to a channel. The routines now
2793 supports sending the channel user mode notifys to the channels
2794 when announcing clients and channels. Affected files are
2795 silcd/server.c and silcd/packet_receive.c.
2797 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2798 It did not actually replace the old channel entry in the cache.
2799 Affected file lib/silcclient/client_notify.c.
2801 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2803 * Fixed a possible crash in silc_packet_send_prepare. It now
2804 assures always that there is enough space in the buffer and
2805 at the tail area of the buffer (for MAC).
2807 Fixed the inbound buffer reallocation in silc_packet_read.
2808 It was old code and did not handle the reallocation correctly.
2811 The affected file is lib/silccore/silcpacket.c.
2813 * Fixed buffer overflow in silc_parse_nickname in the file
2814 lib/silcutil/silcutil.c.
2816 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2818 * make install generates new server keys only if there is not
2821 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2823 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2824 Added check that if the NOREPLY is set then we will not send
2825 the away message. This avoids infinite loop of away messages
2826 if both clients are away. The affected file is
2827 lib/silcclient/client_prvmsg.c.
2829 * Fixed client crash if /NICK was given without arguments.
2830 Affected file lib/silcclient/command.c.
2832 * Server does not send the invite list in INVITE command back
2833 to the client if the list was not altered. Added this notion
2834 to the protocol spec as well. Affected file silcd/command.c.
2836 Fixed possible crash in INVITE command by checking the
2837 value of silc_server_get_client_route command.
2839 * Fixed the INVITE notify type handling. The arguments are now
2840 taken in correct order and client does not crash. The affected
2841 file is irssi/src/silc/core/silc-channels.c.
2843 Removed the "Inviting xxx to channel" message from the
2844 client library away and let the application handle it.
2845 Affected file lib/silcclient/command.c. Added that message
2846 to Irssi SILC client's message formats.
2848 * Fixed CMODE command crash in client. It now checks the
2849 amount of arguments correctly and does not crash. The affected
2850 file is lib/silcclient/command.c.
2852 * Do not create new channel automatically in silc_channels_join
2853 but check whether the channel by that name already exists.
2854 Affected file irssi/silc/core/silc-channels.c.
2856 * Do not send the SERVER_SIGNOFF to router if the disconnected
2857 entity was the router. Affected file silcd/server.c.
2859 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2860 SILC client as it was missing from there.
2862 Added the handling of the KICK notify to the Irssi SILC client
2863 as it was missing. Added "you have been kicked" message to
2864 Irssi SILC client's message modules formats.
2866 Added the handing of the KILL notify to the Irssi SILC client
2867 as it was missing. Added the kill message module formats
2870 The affected file is irssi/src/silc/core/silc-channels.c.
2872 * The router did not save the channel mode the server announced.
2873 Affected file silcd/packet_receive.c.
2875 * Fixed a possible crash in INFO command in server. If the
2876 server did not provide the server info it crashed. Affected
2877 file silcd/command.c.
2879 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2881 * Fixed the GETKEY command in the server to check also the
2882 global list. Otherwise the GETKEY would not work correctly
2883 in normal SILC server. Affected file silcd/command.c.
2885 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2887 * Fixed GETKEY crash, it crashed if the command did not succseed.
2889 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2891 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2892 is now real and not just an macro interface to GMP.
2894 Removed the entire GMP from the source tree and imported new
2895 NSS MPI library instead. Reason for removing GMP is that it is
2896 extremely large and compiles extremely slow. The NSS MPI
2897 is only a few files and compiles in less than 10 seconds.
2898 The speed is also about the same as GMP. The MPI is imported
2899 to lib/silcmath/mpi.
2901 If the system has GMP installed we will still use the GMP.
2902 If it is not then the NSS MPI will be compiled.
2904 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2906 * Merged a long nickname (127 characters long) crash bugfix from
2907 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2909 * Merged a freed memory reference bugfix from Irssi CVS tree.
2910 Affected file irssi/src/core/commands.c.
2912 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2914 * Added the server's public key sving and verification to the
2915 server when performing the SKE. This was missing and the
2916 remote server's (or router's) public key was accepted without
2917 checking whether we have it previously or trust it at all.
2918 Affected file silcd/protocol.c.
2920 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2922 * Check in the silc_server_timeout_remote if protocol is active
2923 and make sure that the protocol's final callback is called so
2924 that all memory if freed. Affected file silcd/server.c.
2926 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2928 * silc_server_whois_send_reply crashed the server if the nickname
2929 was 127 characters long. Affected file silcd/command.c.
2931 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2933 * Added sanity check to the silc_server_new_client. If the hostname
2934 is provided inside username then check that the provided hostname
2935 really is the same as the resolved one. If the hostname was not
2936 resolved then check it from the public key. Affected file is
2937 silcd/packet_receive.c.
2939 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2940 if the server disconnected us and the connection is not valid
2941 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2943 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2944 the library to the lib/silcutil/silcutil.[ch].
2946 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2948 * Close log file after open. Affected file
2949 lib/silcutil/silclog.c.
2951 * Check whether sock == NULL in silc_client_send_packet and return
2952 if it is. Affected file lib/silcclient/silcclient.c.
2954 * Check rec->entry == NULL in the Irssi SILC Client before
2955 sending the channel message. Affecte file is
2956 irssi/src/silc/core/silc-servers.c.
2958 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2960 * Merged a splitted window bugfix from Irssi CVS tree. The
2961 affected file is irssi/src/fe-text/textbuffer-view.c.
2963 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2964 It did not print nickname.
2966 * Improved the distributions system a bit.
2968 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2970 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2971 irssi/src/fe-text/gui-window.c.
2973 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2974 to in-active server. The affected file is
2975 irssi/src/silc/core/client_ops.c.
2977 * Resolve the client in USERS command reply if the entry does
2978 not have username resolved. The affected file is
2979 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2980 command to WHOIS command to really resolve stuff. The USERS
2981 is not used any more in any critical section so WHOIS can
2982 be used even though it might be slower than IDENTIFY.
2984 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2987 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2989 * Changed the protocol API a bit more consistent in the
2990 lib/silccore/silcprotocol.[ch].
2992 * Changed the following headers to ROBODoc format:
2994 lib/silccore/silcpayload.h
2995 lib/silccore/silcprotocol.h
2996 lib/silccore/silcsockconn.h
2998 All core library headers are now formatted.
3000 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3002 * Fixed a bug in Irssi SILC client; do not show that you are
3003 server/router operator if you really are not. Affected file is
3004 irssi/src/silc/core/client_ops.c.
3006 * Renamed silc_command_free_payload to silc_command_payload_free.
3007 Affected file lib/silccore/silccommand.h
3009 * Added silcmath.h to include the prototoypes of various routines
3010 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3013 * Changed the following headers to ROBODoc format:
3015 lib/silccore/silcchannel.h
3016 lib/silccore/silccommand.h
3017 lib/silccore/silcid.h
3018 lib/silccore/silcidcache.h
3019 lib/silccore/silcmode.h
3020 lib/silccore/silcnotify.h
3021 lib/silccore/silcpacket.h
3022 lib/silcmath/silcmath.h
3024 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3026 * Added checking to the server code not to start the server if
3027 ciphers and stuff are not configured properly. Affected files
3028 silcd/serverconfig.[h] and silcd/server.c.
3030 * Changed the layout of the header files of the public interfaces
3031 in the SILC libraries. The new layout supports ROBODoc
3032 documentation tool (and some others) so that it is easy to create
3033 a library reference manual. All the other headers and source
3034 code must still follow the CodingStyle document. Also source
3035 code must not include these ROBODoc stuffs, only the headers.
3036 Furthermore, all public interface headers must now be named
3037 by using `silc' prefix, example: silcapi.h, silccipher.h.
3038 Some files were renamed due to this. All the other headers
3039 must not be used as public interfaces. I will update the
3040 CodingStyle document later. Changed following headers, so far:
3042 lib/silcclient/silcapi.h
3043 lib/silccore/silcauth.h
3044 lib/silccore/silcprivate.h
3045 lib/silccrypt/silcdh.h
3047 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3051 * Removed silc_client_packet_send_flush from the client library
3052 as it is not needed. Affected file lib/silcclient/client.[ch].
3054 * Added printing of message of unresolved authentication method
3055 to the Irssi SILC client. Added it to the module formats.
3056 Removed the same message from the client library.
3058 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3060 * Added new distribution feature, DISTLABEL. Every distribution
3061 can define own preprocessor label that can be used in the
3062 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3063 file distributions, acconfig.h.pre and prepare.
3065 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3067 * Added Makefile.defines_int to include the actual definitions
3068 for Makefile.defines.in. Tested the new distribution system,
3069 created distributions and tested installation.
3071 * Added AWAY message printing to the Irssi SILC client. Added
3072 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3074 * Added SCONNECT command to call the SILC's CONNECT command.
3075 Cannot use CONNECT directly since Irssi uses that internally.
3076 Affected file irssi/src/silc/core/silc-servers.c.
3078 Added ACTION local command. It is same as ME command but takes
3079 the channel as mandatory argument.
3081 Rewrote some of the Irssi's help files to suite for SILC
3084 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3086 * Added Makefile.defines[.in] that should for now on be included
3087 in all Makefile.am file in the source tree. That file includes
3088 all common compilation definitions for SILC source tree.
3090 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3092 * Minor changes to the ./prepare script to change the package
3093 name according the distribution name to the configure.in.
3095 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3097 * Created new distribution system. Added file `distributions'
3098 that defines all the distributions that can be created out of
3099 the SILC source tree. The ./prepare script now reads that
3100 file to determine how to prepare the distributions. The
3101 first argument to the ./prepare is the name of the distribution
3102 and second is the version of the distribution. If given
3103 without arguments it creates the default (toolkit) distribution
3104 with the default version (defined in ./prepare).
3106 All Makefile.am files that are subject to the distributions
3107 are now named as Makefile.am.pre. These are ./Makefile.am
3108 and lib/Makefile.am. Others may be changed later.
3110 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3112 * Added invite list, ban list, some key management and connection
3113 error message printing to module formats in the Irssi SILC client.
3115 * Added new silc_client_set_away_message to set the away message
3116 that is back to the person who sent private message. The
3117 affected file lib/silcclient/silcapi.h and the
3118 lib/silcclient/client_prvmsg.c.
3120 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3122 * Fixed the private message sending in the Irssi SILC client,
3123 added local command KEY to the Irssi SILC client.
3125 Added key management and key agreement message formats to the
3126 irssi/src/fe-common/silc/module-formats.[ch].
3128 Added USERS (alias WHO) printing, server/router operator
3129 indication and LIST command printing to the module formats.
3131 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3133 * Fixed channel joining notify handling, cumode notify handling
3134 from Irssi SILC client.
3136 * Added SILC specific module-formats to the Irssi SILC client so
3137 that SILC specific message hilighting, colors etc is possible.
3138 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3140 Added channel mode, channel user mode, actions, notices,
3141 whois and whowas printing to the the module-formats.c.
3143 * Fixed a bug in channel deletion in the server. The channel
3144 is not left to the cache even if the channel founder auth mode
3145 is set when there are no users anymore on the channel. Affected
3146 file silcd/server.c.
3148 * The silc_net_localhost now resolves the entire hostname including
3149 the domain name. Affected file lib/silcutil/silcnet.c.
3151 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3153 * Changed the ask_passphrase client operation to be ascynchronous.
3154 It has now a completion callback and a context that the
3155 application must call after it has got the passphrase from
3156 the user. Affected files lib/silcclient/silcapi.h,
3157 lib/silcclient/protocol.c, lib/silcclient/command.c and
3160 Added SilcAskPassphrase callback that the application calls
3161 to deliver the passphrase to the library.
3163 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3164 The public key verification and especially a certificate
3165 verification is asynchronous procedure.
3167 Added new SILC_SKE_STATUS_PENDING status to indicate the
3168 request is pending and a callback will be called to finalize
3171 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3172 indicate that remote end did not send its public key (or
3173 certificate), even though we require it. Added check for this
3174 condition in the SKE. This was a security bug, now fixed.
3176 Defined new SilcSKEVerifyCbCompletion callback that is called
3177 when the verification process is completed.
3179 The affected files lib/silcske/silcske_status.h and
3180 lib/silcske/silcske.[ch].
3182 * Changed the verify_public_key client operation to be async
3183 as well. Defined SilcVerifyPublicKey callback that is used to
3184 indicate the success of the public key verification process.
3186 Changed the server and client to use the new async client
3189 * Changed the Irssi SILC client's internal scheduler to be called
3190 twice as many times as it used to be. As a result the client
3191 should be a bit faster now. Affected file is
3192 irssi/src/silc/core/silc-core.c.
3194 * Added support to Irssi SILC client of asynchronous public key
3195 verification and passphrase inquiry. Affected file is
3196 irssi/src/silc/core/silc-core.c.
3198 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3200 * Do not say "You have left channel %s" in client library.
3201 Moved it to the application. Affected files are
3202 lib/silcclient/command.c and silc/client_ops.c.
3204 * Fixed silc_client_get_clients. Command context was not
3205 duplicated and was freed memory in the callback. Affected
3206 file lib/silcclient/idlist.c.
3208 * Do not say "you are now talking..." on JOIN command in the
3209 client library. The appliation must handle it.
3211 * Do not say ".. changed topic to" in command reply in the
3212 client libary. The application must handle it.
3214 * Fixed TOPIC command sending in the client library.
3216 * Fixed a memory leak in silc_client_command_free in the file
3217 lib/silcclient/command.c.
3219 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3221 * Imported a modified version of Irssi client to the source tree.
3222 The Irssi will be used to create a new client called
3223 Irssi SILC. Imported to irssi/.
3225 Added silc_core_init_finish function to the Irssi. Affected
3226 file irssi/configure.in.
3228 A lot changes in the Makefile.ams around the irssi tree.
3230 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3232 * Do not rehash if the new size is same as the old size of the
3233 hash table, in the silc_hash_table_rehash*. The affected file
3234 lib/silcutil/silchashtable.c.
3236 * Replaced hash_table_del_by_context calls from the server
3237 (when channel->user_list and client->channels) to the
3238 hash_table_del as it is sufficient and faster.
3240 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3242 * Added silc_hash_table_list, silc_hash_table_get and the
3243 SilcHashTableList structure to provide an alternative way to
3244 traverse the hash table. The affected files are
3245 lib/silcutil/silchashtable.[ch].
3247 * Changed the server's idlist routines to use the hash table
3248 routines to optimize the code.
3250 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3252 * Replaced the client entry's `channel' list and channel entry's
3253 `user_list' list to hash tables for optimized lookup. Changed
3254 the code to use the hash table interface around the code.
3255 Affected file lib/silcd/idlist.[ch].
3257 * Added `auto_rehash' boolean argument to the function
3258 silc_hash_table_alloc to indicate whether the hash table should
3259 auto-rehash when it thinks is appropriate time. It will
3260 increase the hash table size if the there is twice as much
3261 entries in the table than the size of the table, and will
3262 decrease the size if there are twice as less entries than
3263 the size of the table.
3265 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3267 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3269 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3271 * silc_idcache_purge_by_context deletes the entry now by context
3272 as it is supposed to do. Affected file lib/silccore/idcache.c.
3274 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3275 client is not anymore valid (WHOWAS givens the info) and not
3276 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3278 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3280 * Removed the `data' and `data_len' arguments from the ID Cache
3281 interfaces and added `name' argument. ID Cache does not handle
3282 anymore the binary data only a names associated with given ID.
3284 * When hashing a Client ID with silc_hash_id the entire ID is
3285 not hashed anymore, instead only the hash of the Client ID is
3286 hashed. This way we can access the Client ID from the cache
3287 with Client ID but with the hash of the ID (which is a hash of
3288 the nickname) as well without any difference in performance.
3290 Added also silc_idcache_find_by_id_one_ext to do one on one
3291 searching when we have the actual ID. Added also function
3292 silc_hash_client_id_compare. The affected files are
3293 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3295 * When hashing the name associated with a ID it is always done
3296 in lowercase. This way we can access the cache without worrying
3297 about case-sensitivity, even though, for example nicknames are
3300 * Fixed a bug in server with channel message sending. It put
3301 wrong ID type as destination ID. The affected file
3302 silcd/packet_send.c.
3304 * silc_idcache_del_by_context now deletes from all hash tables
3305 by context. Affected file lib/silccore/idcache.c.
3307 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3309 * Changed the client library to use the new ID Cache interface.
3310 Changes around the source tree.
3312 * Added silc_hash_table_rehash_ext to rehash with specific
3313 hash function. Affected file lib/silcutil/silchashtable.[ch].
3315 * Added silc_hash_string_compare to compare two strings in the
3316 hash table. Affected file lib/silcutil/silcutil.[ch].
3318 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3320 * Added new function silc_idcache_del_by_context into the
3321 lib/silccore/idcache.[ch].
3323 * Changed the server's ID list routines to use the new ID Cache
3324 interface. Changes around the source tree.
3326 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3328 * Added silc_hash_table_del[_by_context]_ext functions in to the
3329 lib/silcutil/silchashtable.[ch].
3331 Removed silc_hash_table_find_all* routines and added new
3332 silc_hash_table_find_foreach to replace them.
3334 Added silc_hash_table_replace_ext function as extended
3335 replacing function. Separated the simple hash table interface
3336 from the extended hash table interface in the file
3337 lib/silcutil/silchashtable.h.
3339 * Fixed minor bugs and changed it to use some of the new
3340 hash table functions in lib/silccore/idcache.c
3342 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3344 * Added new function silc_hash_table_find_all to return all keys
3345 in the hash table by the specified key. As the hash table is
3346 collision resistant it also makes it possible to have several
3347 duplicate keys in the hash table. This function may be used to
3348 find all of the keys from the hash.
3350 Added user_context arguments to the SilcHashFunction,
3351 SilcHashCompare and SilcHashDestructor to deliver user specified
3354 Added new fuctions silc_hash_table_find[_all]_ext to do
3355 extended lookup with specified hash and compare functions and
3356 specified user contexts.
3358 Added new function silc_hash_table_add_ext to add the key
3359 with specified hash function and user context.
3361 Added new function silc_hash_table_foreach to traverse all
3362 entrys in the hash table. Added SilcHashForeach callback
3365 Added new function silc_hash_table_del_by_context to delete
3366 the entry only if the context associated with the key matches.
3368 Affected files are lib/silcutil/silchashtable.[ch].
3370 * Removed silc_hash_[server/client/channel]_id and added just
3371 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3372 silc_hash_id_compare to compare two ID's using as the hash table
3373 comparison function. Added also silc_hash_data to hash
3374 binary data and silc_hash_data_compare to compare it.
3376 * Removed silc_idlist_find_client_by_hash as it is not needed
3377 anymore. Affected file silcd/idlist.[ch].
3379 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3380 to use internally the SilcHashTable. The new ID Cache is a lot
3381 faster than the old one. Some of the ID Cache interface was also
3382 rewritten and obsolete and stupid functions were removed.
3384 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3386 * Added entry_count field to the SilcHashTable to keep the number
3387 of the entries in the table. Implemented the function
3388 silc_hash_table_rehash. Added new function
3389 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3391 Fixed a minor bug in silc_hash_table_free.
3393 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3394 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3395 into the lib/silcutil/silcutil.[ch].
3397 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3399 * Implemented a collision resistant hash table into the
3400 lib/silcutil/silchashtable[ch]. See the header and the source
3401 for the SilcHashTable API.
3403 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3405 * Merged dotconf version 1.0.2 into lib/dotconf.
3407 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3409 * Do not compile anything in lib/silcsim/* if the SIM support
3410 is not enabled. The tree should now compile without problems
3413 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Compiled the SILC under cygwin. Compiled and tested briefly
3416 without problems. More tests needed. The SIMs didn't compile
3419 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3421 * Fixed possible crash in silc_get_username in the
3422 lib/silcutil/silcutil.c.
3424 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3426 * Fixed a va_arg in silc/client_ops.c.
3428 * Oops, RC5 routines were named AES and caused some problems
3429 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3431 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3433 * Added new SilcIDIP structure into the lib/silccore/id.h and
3434 replaced the old `ip' fields from all SILC ID's to that type.
3435 This is a step towards IPv6 support.
3437 The silc_id_get_len takes now the ID as an extra argument.
3438 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3439 both IPv4 and IPv6 based ID's.
3441 The affected files are lib/silccore/id.[ch] and other files
3442 around the tree using these routines.
3444 * Removed the ID length arguments in server from various
3445 silc_server_send_notify_* routines -> they are not needed
3448 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3450 * Fixed memory leak in silc_encode_pem_file in the file
3451 lib/silcutil/silcutil.c.
3453 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3455 * Check minor version as well in the SKE. Affected files are
3456 silcd/protocol.c and lib/silcclient/protocol.c.
3458 * Added --identifier option to the server so that an identifier
3459 can be when creating the public key for the server. Affected
3460 file is silcd/silcd.c.
3462 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3463 lib/silccrypt/silcpkcs.c.
3465 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3467 * Register default ciphers and stuff when using -C option with
3468 the server. Affected file sildc/silcd.c.
3470 * Put back the servers public key filename format, it is better
3471 than the new one. For now, the client keys are saved with the
3472 new filename format. The affected file silc/client_ops.c.
3474 * Implemented the Cipher API for the rest of the ciphers that
3475 did not implement it or implemented it the wrong way.
3477 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3479 * Register default ciphers and stuff when using the -S option
3480 in the client. Affected file silc/silc.c. Same also when
3481 creating new key pair with -C option.
3483 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Fixed the silc_verify_public_key client operation function to
3486 save the public keys differently. The fingerprint is now
3487 used as filename and not the hostname. This way also the
3488 client keys are saved uniquely and not with hostnames. The
3489 affected file is silc/client_ops.c.
3491 * Trimmed the silc_hash_fingerprint function to remove extra
3492 whitespaces from the end of the fingerprint. The affected
3493 file is lib/silccrypt/silchash.c.
3497 * Added silc_cipher_register_default function to register all
3498 default ciphers. It can be used when configuration files
3499 does not exist and the application does not want any specific
3500 ciphers in any specific order.
3502 The SilcDList is now used as silc_cipher_list dynamically
3503 allocated cipher list. Removed the static list all together
3504 and now all ciphers must be allocated to the dynamic list.
3505 The silc_cipher_alloc routine was changed to check only the
3508 All silc_cipher_* routines that used to return int returns
3511 The affected files lib/silccrypt/silccrypt.[ch].
3513 * The same thing was done to silc_hash_* as for silc_cipher_*
3514 routines. Affected files lib/silccrypt/silchash.[ch].
3516 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3517 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3518 Added also silc_pkcs_[un]register[_default] functions.
3519 Removed the data_context from the PKCS API.
3521 * Added silc_hmac_register_default function to register default
3522 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3523 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3524 to unregister all hmacs at once.
3526 * Register the default ciphers, hash functions, PKCSs and HMACs
3527 if client's configuration file does not exist. The affected
3530 * The client did not load the hash functions from the SIM
3531 modules at all. Added support for this. Affected file is
3532 silc/clientconfig.c.
3534 * When decoding public key with silc_pkcs_public_key_decode, check
3535 the supported algorithm only if PKCS are registered. Affected
3536 file lib/silccrypt/silcpkcs.c. The same was done with the
3537 silc_pkcs_private_key_decode.
3539 * Fixed the SILC List routines to keep the list always in order.
3540 It used to change the list's order when traversing the list but
3541 not it preserves the order. Affected file lib/trq/silclist.h.
3543 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3545 * Added the client library to use the SilcSocketConnection's
3546 reference counter (by silc_socket_dup) to prevent the bug that
3547 the socket object may be freed underneath async operation.
3549 * The name resolv library checking fixes in the configure.in.pre.
3552 * Created new version of the protocol drafts for future
3553 development. The -03 drafts are the ones that will be changed
3554 in the trunk now and the -02 will remain as they are.
3556 * Send list of CUMODE notifys to the router when announcing
3557 the channel users to the router. Affected file silcd/server.c.
3558 If the router receiving channel founder CUMODE for a channel
3559 that already has channel founder it will send CUMODE notify
3560 to the sender to remove the channel founder rights from the
3561 announced client. Affected file silcd/packet_receive.c.
3563 * The CUMODE notify may now use Server ID as well as the entity
3564 who changes the mode. Updated protocool specs.
3566 * Updated INSTALL and README files.
3568 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3570 * New web pages in the http://silc.pspt.fi. The pages was
3575 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3577 * Implemented the [DenyConnectin] config section in the server.
3578 Added silc_server_config_denied_conn to check whether incoming
3579 connection is denied. Affected file silcd/serverconfig.[ch].
3581 * Do not check the ports when checking the incoming configuration
3582 data if the port is 0, meaning any. Affected file is
3583 silcd/serverconfig.c.
3585 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3587 * Fixed buffer overflow in silc_string_compare in the file
3588 lib/silcutil/silcutil.c.
3590 * Fixed double free in silc_server_command_leave in the file
3593 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3595 * Fixed the version checking in the server. Affected file is
3598 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3600 * Fixed the configuration data fetching when accepting new
3601 connections in the server. Affected file silcd/server.c.
3603 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * Added `sender_entry' argument to the function
3606 silc_server_packet_relay_to_channel so that we can check
3607 whether some destination actually belongs to the same route
3608 the sender belongs (ie, we must not resend the packet to the
3609 sender). Affected file silcd/packet_send.[ch].
3611 * Added `servername' field to the SilcClientEntry in the server
3612 to hold the name of the server where client is from. Affected
3613 file is silcd/idlist.h.
3615 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3617 * Moved the channel message encrypting in the router betwen
3618 router connections from silc_server_channel_message to the
3619 silc_server_packet_relay_to_channel since we want to check
3620 whether we have anybody channel before encrypting anything.
3621 Affected files silcd/packet_[receive/send].c.
3623 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * Fixed the [AdminConnection] server config section to support
3626 multiple entries. Affected file silcd/serverconfig.c.
3628 * Added support into the server to check the validity of the
3629 incoming connection before executing any KE or authentication
3632 * The connection configuration is now saved to the KE and
3633 connection auth protocol contexts and not fetched anymore in
3634 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3636 * The local hosts listenning address and port is also resolved
3637 now when starting the server. We want to have the socket object
3638 to include the real address and port for the listener. Added
3639 new function silc_net_check_local_by_sock into the files
3640 lib/silcutil/silcnet.[ch].
3642 * Fixed a broadcast bug in server -> do not broadcast if we
3645 * Fixed a routing bug. Do not route broadcast packets ever.
3646 Broadcast packets must be processed always and not routed since
3647 they may be destined to some other host than yourself and thus
3648 would get routed without no good reason. Affected file is
3651 * Added function silc_server_config_is_primary_route to check
3652 whether primary router connection has been configured (a router
3653 configuration that we are initiating). If there is not, we
3654 will assume that there is only two routers in the SILC network
3655 and we will use the incoming router connection as our primary
3656 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3658 * Changed the order of the broadcasting. Broadcast _after_ the
3659 packet has been processed not before. Affected file is
3662 * Fixed a [ClientConnection] parsing bug. The port was never
3663 parsed correctly thus resulting to port 0. Affected file
3664 silcd/serverconfig.c.
3666 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3667 argument and did not set the broadcast packet flag. Affected
3668 file silcd/packet_send.c. Fixed same bug in the function
3669 silc_server_send_notify as well.
3671 * If we receive NEW_ID packet for our own ID in the server, ignore
3674 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * Removed the nickname from the Private Message Payload.
3679 Updated the code and the protocol specs.
3681 * Updated protocol specs for submitting to the IETF.
3683 * Tweaked the Random Number Generator a bit. Affected file
3684 lib/silccrypt/silcrng.c. Exported a new function
3685 silc_rng_[global]_add_noise which can be used to add more
3688 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3690 * Do not parse packets with different timeout when protocol
3691 is active -> may cause problem with rekey. Affected file
3694 * When server receives signoff notify it must not create
3695 new channel key if the client is on any channels since the
3696 sender of the signoff notify will create it.
3698 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3700 * Added printing of error messages during SKE protocol from the
3701 failure packet sent by server during SKE. Affected file
3704 * Removed the client's failure_callback handling with timeout
3705 and handle it immediately when received.
3707 * The SKE library returned wrong type in SUCCESS and FAILURE
3708 packets. They must be 32 bit MSB not 16 bit MSB.
3710 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3712 * Ok, rewrote the logic of the re-key and now it seems to work.
3713 I tested it on high traffic with frequent re-keys without
3714 problems. Added hmac_receive (and renamed hmac to hmac_send)
3715 in SilcClientConnection in lib/silcclient/client.h and
3716 in SilcIDListData in silcd/idlist.h. Also, removed the
3717 SilcPacketParserContext's cipher and hmac fields as they are
3718 not needed anymore and actually caused some problems when
3719 the ciphers and hmac's changed underneath the packet parser.
3721 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3723 * If re-key protocol is active then process the incoming packets
3724 synchronously since we must assure that icoming packets encrypted
3725 with the old key is processed before the new keys is set to
3726 use. This is true other packets than for REKEY packets.
3727 Affected file silcd/server.c. The same was done to client library
3728 as well, affected file lib/silcclient/client.c.
3730 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3732 * Fixed bug in client and server to accept the force send if
3733 the packet is send from silc_[server/client]_packet_process
3734 function. Otherwise the packets are never delivered, oops.
3736 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3738 * Disable force sending of packets when REKEY protocol is active.
3739 We must assure that no packet is sent directly when rekey is
3740 performed. All packets must be sent through packet queue.
3741 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3742 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3743 function is silc_[server/client]_packet_send_real to check
3746 * Replaced the SIM paths from example config files to
3747 /usr/local/modules. Also, make install creates now
3748 /usr/local/silc/logs directory to hold all the SILC server
3751 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Made the configure.in.pre work on Solaris. Patch by salo.

3762 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3764 * When MAC computation fails the silc_packet_decrypt returned 0
3765 even though it was supposed to return -1. Fixed this. The
3766 affected file is lib/silccore/silcpacket.c.
3768 * Do not replace the config files in /etc/silc (in make install)
3769 if they already exist. Affected file ./Makefile.am.
3771 * Do not send re-key packets immediately but through packet queue.
3772 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3774 * Changed silc_net_check_host_by_sock to return FALSE if the
3775 IP/DNS could not be resolved. Though, it returns the IP address
3776 now even if it could not resolve it (but returns also FALSE).
3777 Affected file lib/silcutil/silcnet.[ch].
3779 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3781 * Added silc_pkcs_decode_identifier to decode the public key's
3782 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3783 Added also silc_pkcs_free_identifier. Added also new context
3784 SilcPublicKeyIdentifier.
3786 * Added -S option to the silc client. It is used to dump the
3787 contents of the specified public key file.
3789 * Changed the PKCS api to return the public key length when
3790 setting the public key.
3792 * Fixed a fatal bug in the public and private key file loading.
3793 Affected file lib/silccrypt/silcpkcs.c.
3795 * Execute the packet parsing for client with zero (0) timeout
3796 if the protocol is active. Affected file silcd/server.c.
3798 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3800 * Made the key generation options to the silcd program. Added
3801 -C option, equivalent to client's option.
3803 * Added new [ServerKeys] config section to the server. It
3804 configures the server's public and private key.
3806 * Defined generic Public Key Payload into the protocol
3807 specification to send specific type of public keys and
3810 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3811 public key or certificate.
3813 * Implemented the GETKEY command to the server and to the
3814 client library and on user interface.
3816 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3818 * Made preliminary `make install' work.
3820 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3822 * Added SilcServerRekey context into silcd/idlist.h.
3824 * Added the PFS support as defined in the specification to the
3825 SKE protocol. Affected files lib/silcske/*.c.
3827 * Added `ske_group' field to the SilcServerRekey context to hold
3828 the number of the SKE group that is used with PFS in re-key.
3829 Affected file silcd/idlist.h.
3831 * Added PFS re-key support to the server. Affected file is
3834 * Added silc_protocol_cancel to cancel execution of the next
3835 state of the protocol. Affected file is
3836 lib/silccore/silcprotocol.[ch].
3838 * Added the re-key support with and without PFS to the client
3839 library. Re-key is performed once in an hour, by default.
3841 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3842 Added silc_client_rekey_callback and silc_client_rekey_final.
3843 Affected files are lib/silcclient/protocol.[ch] and
3844 lib/silcclient/client.[ch].
3846 * Removed the `hmac_key' and `hmac_key_len' fields from the
3847 SilcClientConnection structure; not needed. Affected file is
3848 lib/silcclient/client.h.
3852 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3854 * Do not ask whether user wants to use the negotiated private key
3855 for private messages, just use it. Affected file is
3856 silc/local_command.c.
3858 * Added `send_enc_key' and `enc_key_len' fields to the
3859 SilcIDListData structure since they are needed in the re-key
3860 phase. Affected file is silcd/idlist.[ch].
3862 * Implemented the simple re-key protocol into the server.
3863 Affected files silcd/server.c and silcd/protocol.[ch]. The
3864 re-key will be performed once in an hour, by default.
3866 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3867 Added silc_server_rekey, silc_server_rekey_callback and
3868 silc_server_rekey_final.
3870 * Removed Tunneled flag from the protocol. Updated the code
3871 and the specifications.
3873 * Adde `pfs' field to the SilcIDListData to indicate whether
3874 the PFS is to be performed in the re-key. Affected file is
3877 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3879 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3880 int64 of at least the xintXX size. If void * is less that 4
3881 bytes uint32 * will be used. Defined bool as boolean.
3883 * Changed _ALL_ unsigned long and unsigned int to uint32,
3884 unsgined short to uint16 in the source tree.
3886 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3887 not handle clients that has entry->data.registered == FALSE.
3888 They are not in the network anymore. Affected file is
3891 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Implemented the sending of the SERVER_SIGNOFF notify in the
3894 server. Affected file is silcd/server.c.
3896 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3897 Added also silc_notify_payload_encode_args into the
3898 lib/silccore/silcnotify.[ch].
3900 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3901 Affected file silcd/packet_receive.c.
3903 * Implemented the SERVER_SIGNOFF notify handling in the client
3904 library. Affected file lib/silcclient/client_notify.c. Also,
3905 implemnted the printing of the SERVER_SIGNOFF info to the
3906 application. Affected file silc/client_ops.c.
3908 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3909 if the deleting was successful. Affected file silcd/idlist.[ch].
3911 * Added support for public key authentication in the connection
3912 authentication protocol in the client library. Affected file
3913 lib/silcclient/protocol.c.
3915 * Changed the server's silc_idlist_get_clients_by_* interface
3916 to support already allocated array so that new entries may be
3917 added to pre-allocated array. Affected file silcd/idlist.[ch].
3918 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3919 and command replies.
3921 * All command reply functions in the server now calls the
3922 pending command callback even if error occured. This way the
3923 error will be delivered to the client as well. Affected files
3924 silcd/command.c and silcd/command_reply.c.
3926 * Fixed INFO command to return local server's info if no server
3927 was provided. Affected file lib/silcclient/command.c.
3929 * Removed RESTART command for good. Updated the code and the
3932 * Rewrote parts of the task system. It is a bit simpler now.
3933 Removed unsued task priorities. The affected files are
3934 lib/silcutil/silctask.[ch].
3936 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3938 * Moved the USERS printing from the library to the application.
3939 Affected files lib/silcclient/command.c and silc/client_ops.c.
3941 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3945 * Added channel key re-key support. The re-key is perfomed
3946 only by the router and is done once in an hour. Added `rekey'
3947 field to the SilcChannelEntry in the server. Affected files
3948 silcd/server.c and silcd/idlist.h.
3950 * Added silc_task_unregister_by_context into the file
3951 lib/silcutil/silctask.[ch].
3953 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3955 * Added SILC_UMODE_GONE mode to indicate when the client is not
3956 present in the SILC network. Added also support to the local
3957 command AWAY that will set this mode. Added support of showing
3958 "xxx is gone" in WHOIS command. The USERS command shows the
3959 gone status as well.
3961 * Fixed setting server and router operator privileges in the
3962 server's UMODE command. Affected file silcd/command.c.
3964 * Merged the SKE KE1 and KE2 payloads into one payload. The
3965 new KE payload is equivalent to the old KE2 payload.
3967 Cleaned up the SKE Start Payload parsing. It now uses the
3968 simple buffer unformatting to do the parsing. A lot faster
3971 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3972 to the SKE that is used to indicate whether both of the SKE
3973 parties should perform authentication. By default only the
3974 responder performs authentication. By setting this flag also
3975 the initiator must do authentication. By default it is unset
3976 since in normal SKE case, client to server connection, only
3977 the responder should do authentication. When doing SKE between
3978 two clients both should perform authentication. Updated the
3979 code and the protocol specs.
3981 * A little fix to IDENTIFY command in the server. Search the
3982 client first by hash not nickname. Affected file is
3985 * Fixed the silc_client_close_connection to support closing
3986 the client to client connections wihtout deleting too much
3987 data. Affected file lib/silcclient/client.c.
3989 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3990 are received if protocol used to be active but is not anymore
3991 the application would crash due to NULL pointer dereference.
3992 Affected files silcd/server.c and lib/silcclient/client.c.
3994 * Added `hash' field to the SilcClientConnection to include
3995 the hash function negotiated in the SKE protocol.
3997 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3998 to set the channel founder authentication data. A client can
3999 claim the founder rights later by providing the authentication
4000 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4001 This way the channel founder can regain the channel founder
4002 privileges even it is left the channel. This works only on
4003 local server and the client must be connected to the same
4004 server to be able to regain the founder rights. Updated the
4005 protocol specs accordingly.
4007 Added support to the CMODE command in the client to set the
4008 founder auth data. Read the README to see how to set it.
4010 Added support to the CUMODE command to claim the founder
4011 rights. Read the README to see how to do it.
4013 Added support for the founder authentication to the Channel
4014 Entry in the server. Affected file silcd/idlist.h.
4016 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4017 server's CMODE command. Affected file silcd/command.c.
4019 * Added the following new functions into lib/silccore/silcauth.[ch]:
4020 silc_auth_get_method and silc_auth_get_data.
4022 * The server now saves the remote hosts public key to the
4023 SilcIDListData pointer. Affected file silcd/protocol.c.
4025 * The normal server now does not remove the channel entry from
4026 the cache if the founder authentication data is set. It used
4027 to remove it if the founder was the last one on the channel on
4028 the server and left the channel. The auth data is saved and
4029 if the channel is re-joined later the old entry is used with
4030 the old auth data. Affected files silcd/command_reply.c and
4033 * Removed the `pkcs' field from the SilcIDListData structure
4034 in the server; it is not used. Affected file silcd/idlist.h.
4036 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4038 * Fixed packet processing on slow links. Partial packets were
4039 never re-processed because the incoming data buffer was cleared
4040 by the application. Application must not directly clear the
4041 sock->inbuf, the packet processing routines handle it. Fixed
4042 this in client library and in server.
4044 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4046 * Fixed the WHOIS and IDENTIFY send reply function to really
4047 check whether to send list or just one entry. Affected file
4050 * Cleaned up the LEAVE command's channel key distribution. The
4051 affected file silcd/command.c.
4053 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4054 can enforce the channel mode as well. In that case the ID
4055 includes the ID of the server. The code now enforces the
4056 mode change if the router have different mode than the server.
4058 * The notify client operation with CMODE_CHANGE notify can now
4059 return NULL client_entry pointer if the CMODE was not changed
4060 by client. Application must check for this.
4062 * Added <Server ID> argument to INFO command to support server
4063 info fetching by Server ID.
4065 * Added silc_server_announce_get_channel_users to get assembled
4066 packets of channel users of the specified channel. Affected
4067 file silcd/server.[ch].
4069 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4070 was freed underneath the ID Cache.
4072 * Re-announce clients when the server received CHANNEL_CHANGE
4073 notify from the router. Affected file silcd/packet_send.c.
4075 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4077 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4078 crashed since it did not handle the fact that there is no cipher
4079 called "3" and didn't check the error condition. Now fixed.
4081 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4082 flag. It can be used to send message requests.
4084 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4086 * Implemented the RESTART command in the client.
4088 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4089 notice type messages. Added notice printing to the user
4092 * The channel keys are not re-generated if the channel's mode
4093 is PRIVKEY, ie private key on the channel exists. Affected
4094 files silcd/server.c and silcd/command.c.
4096 * Fixed a little bug in channel message delivery when channel
4097 private keys are set in the server. Affected file is
4098 silcd/packet_send.c.
4100 * Changed the setting on channel->on_channel = TRUE from the
4101 silc_client_save_channel_key to the JOIN command reply. The
4102 key payload is not received if the private channel key is set.
4103 Affected file lib/silcclient/command_reply.c and the
4104 lib/silcclient/client_channel.c.
4106 * When the CMODE_CHANGE notify is sent and the channel private
4107 key mode is removed the channel key must be re-generated in
4108 other cells as well. Added this support for the router in the
4109 silcd/packet_receive.c.
4111 * Added new local command NOTICE to send notice message on
4112 channel. Affected file silc/local_command.[ch].
4114 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4116 * Added new local command ME to the client. It is used to send
4117 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4118 some action. Affected file silc/local_command.[ch].
4120 * Changed channel_message and private_message client operations
4121 to deliver the message flags to the application. Added also
4122 the `flags' arguments to the silc_client_send_channel_message
4123 and silc_client_send_private_message functions. Affected file
4126 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4128 * Redefined the Private Message Payload to support private message
4129 keys and to support the new private message flags. Updated
4130 the protocol specs. Flags makes it possible to have for example
4131 CTCP style messages.
4133 * Added new type SilcPrivateMessagePayload and defined an API
4134 for it in the lib/silcclient/silcprivate.[ch].
4136 * Tested private message private keys successfully. Tested the
4137 private message key set, unset and list commands with the new
4140 * Redefined the Channel Message Payload to include the channel
4141 message flags (equal with private message flags) to support
4142 for example CTCP style messages.
4144 * Defined some of the message (for channel and private message)
4145 flags. Updated the protocol specs and added the flags to the
4146 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4148 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4150 * Added SilcKeyAgreementStatus type to the key agreement routines
4151 to indicate the current status and error if one occured.
4152 The status types are defined in the lib/silcclient/silcapi.h.
4154 * Added new local command KEY that is used to set and unset private
4155 keys for channels, set and unset private keys for private messages
4156 with remote clients and to send key agreement requests and
4157 negotiate the key agreement protocol with remote client. The
4158 key agreement is supported only to negotiate private message keys,
4159 it currently cannot be used to negotiate private keys for channels,
4160 as it is not convenient for that purpose.
4162 * Fixed a minor pending callback setting bug in the function
4163 silc_client_get_client_by_id_resolve, now the function works.
4164 Affected file lib/silcclient/idlist.c.
4166 * Added function silc_net_get_local_port to get local bound
4167 port by socket. Added to lib/silcutil/silcnet.[ch].
4169 * Added `sockets' and `sockets_count' fields to the SilcClient
4170 object. They hold the sockets of the listenning sockets in
4171 the client. Listenning sockets may be for example the key
4172 agreement server. Affected file lib/silcclient/client.[ch].
4173 Added functions the silc_client_add_socket and the
4174 silc_client_del_socket. They are exported to the application
4177 * Added ~./silc/clientkeys to support other client's public keys.
4179 * Renamed verify_server_key client operation to verify_public_key
4180 and added one argument to indicate the type of the connection
4181 (server, client etc.).
4183 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4185 * Added silc_server_connection_auth_request to handle the
4186 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4187 silcd/packet_receive.[ch].
4189 * Added silc_server_send_connection_auth_request into the
4190 silcd/packet_send.c to send the connection auth request packet.
4192 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4195 * Fixed the public key authentication in responder side in the
4196 server. The `auth_data' pointer includes the SilcPublicKey
4197 not the path to the public key. Affected file silcd/protocol.c.
4199 * Implemented the public key authentication in the initiator side
4200 in the server. Affected file silcd/protocol.c.
4202 * Removed the [RedirectClient] config section from the server
4203 configuration. Is not needed and I don't want to implement it.
4205 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * Cleaned up the CMODE command in the server. It now works
4208 correctly and supports all the modes defined in the protocol.
4209 Affected file is silcd/command.c.
4211 * Added `hmac_name' field to the SilcChannelEntry in the server
4212 to hold the default HMAC of the channel. It can be set when
4213 creating the channel (with JOIN command). Affected files
4216 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4217 type to indicate the change of the current cipher and hmac
4218 on the channel. Client can safely ignore the <cipher> argument
4219 (if it chooses to do so) since the CHANNEL_KEY packet will
4220 force the channel key change anyway. The <hmac> argument is
4221 important since the client is responsible of setting the new
4222 HMAC and the hmac key into use.
4224 * Fixed the CMODE command in the client library as well.
4226 * Tested CMODE command in router environment successfully.
4228 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4230 * Show the version of the remote client (or server) when connecting
4231 to the server. It is logged to the log file. Affected file
4232 is silcd/protocol.c.
4234 * Fixed the KILLED notify handling in the client library. The
4235 client must be removed from all channels when receiving the
4238 Also, do not remove the client entry when giving the KILL
4239 command but when the KILLED notify is received.
4241 * Removed silc_idlist_find_client_by_nickname from the server.
4242 Not needed anymore. Affected files silcd/idlist.[ch].
4244 * Implemented the CHANNEL_CHANGE notify type handling to the
4245 server. Affected file silcd/server.c.
4249 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Added silc_server_send_notify_invite to send the INVITE
4252 notify between routers.
4254 * Implemented the INVITE command correctly to the server.
4256 * Implemented the INVITE notify type handling in the server.
4258 * Implemented the INVITE command to the client library and on the
4261 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Added function silc_server_get_client_resolve to find the
4264 client entry by ID from all ID lists and then resolve it
4265 (using WHOIS) if it cannot be found. Affected file is
4268 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4270 * Implemented the BAN command to the client library.
4272 * The JOIN command in the server now checks the invite list
4275 * Changed the silc_command_reply_payload_encode_va and the
4276 silc_command_payload_encode_va to support that if argument is
4277 NULL it ignores and checks the next argument. Affected file
4278 lib/silccore/silccommand.c.
4280 * Added silc_server_send_notify_ban to send the BAN notify
4281 type between routers.
4283 * Chaned the silc_notify_payload_encode to support that if
4284 argument is NULL it ignores and checks the next argument.
4285 Affected file lib/silccore/silcnotify.c.
4287 * Tested ban lists in router environment successfully.
4289 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4291 * Implemented BAN command to the server, in silcd/command.[ch].
4293 * Removed the BAN and INVITE_LIST modes from the CMODE command
4296 * Added function silc_string_match to regex match two strings.
4297 Affected files lib/silcutil/silcutil.[ch].
4299 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4301 * Redefined parts of the SilcChannelEntry in the server to support
4302 the new ban and invite lists.
4304 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4306 * Redefined the INVITE command. The same command can be used to
4307 invite individuals to the channel but also to manage the invite
4308 list of the channel (to add to and remove from the invite list).
4309 Updated the protocol specs.
4311 * Added new command SILC_COMMAND_BAN that can be used to manage
4312 the ban list of the channel. Updated the protocol specs.
4314 * Removed the channel modes: the SILC_CMODE_BAN and the
4315 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4316 in the CMODE command. The equivalent features are now available
4317 using INVITE and BAN commands. Updated the protocol specs.
4319 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4320 in the network about change in the current ban list. The notify
4321 type is not used by the client.
4323 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4324 support the invite lists.
4326 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4328 * Added new function silc_string_regexify that converts string
4329 including wildcard characters into regex string that can
4330 be used by the GNU regex library. Added into the file
4331 lib/silcutil/silcutil.[ch].
4333 Added silc_string_regex_combine to combine to regex strings
4334 into one so that they can be used as one regex string by
4335 the GNU regex library. Added into the file
4336 lib/silcutil/silcutil.[ch].
4338 Added silc_string_regex_match to match two strings. It returns
4339 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4341 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Imported GNU regex to the soruce tree into lib/contrib.
4344 Fixed some compiler warning from the regex.c.
4346 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4348 * Fixed MOTD command in the server to work in router environment.
4350 * Fixed the MOTD command in the client library to support
4351 the server argument in the command.
4353 * Added `nickname_len' argument to the silc_idlist_add_client
4354 in the server, as the `nickname' argument may be binary data
4357 * Added silc_idlist_get_channels to return all channels from
4360 * Implemented LIST command to the server. Affected file is
4363 * Implemented the LIST command to the client library and on the
4366 * Added [<user count>] argument to the LIST command reply.
4367 With private channels the user count is not shown.
4369 * Updated TODO and README.
4371 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4373 * The client entry's data.registered must be TRUE even with
4374 global client entry on global client list. The data.registered
4375 is used to check whether the client is anymore in the network,
4376 for example with WHOWAS command so it must be valid.
4378 * Fixed the WHOWAS command in the server. It now actually works
4379 in router environment. Added function into silcd/command_reply.c
4380 silc_server_command_reply_whowas_save.
4382 * Added silc_idlist_purge function to the silcd/idlist.c
4383 to periodically purge the ID Cache.
4385 * Fixed INFO command in the server. It works now in router
4386 environment. Added <server name> argument to the INFO command
4387 reply. Updated the protocol specs.
4389 * Fixed minor bug in silc_idcache_purge to not purge if the
4390 expire value is zero.
4392 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4393 they were buggy because of the WHOWAS information.
4395 * Fixed local command MSG to handle the async resolving of
4396 the remote client properly. It used to fail the first MSG.
4397 Affected file silc/local_command.c.
4399 * Added `data_len' field to SilcIDCache context.
4401 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4403 * Update TODO. Todo in commands in the server.
4405 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4407 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4408 used by routers as broadcast packet to inform other routers
4409 about the changed user mode.
4411 Implemented the notify handling in the server. Affected file is
4412 silcd/packet_receive.c. Added the function
4413 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4415 * Added new generic Channel Payload and deprecated the New Channel
4416 Payload. The New Channel Payload is now the generic Channel
4419 * Added new argument `mode' to the silc_server_send_new_channel
4420 as it is required in the Channel Payload now.
4422 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4423 and created a new and real SilChannelPayload to represent the
4424 new generic Channel Payload. Implemented the encode/decode
4425 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4427 * Added silc_server_get_client_channel_list to return the list
4428 of channels the client has joined for WHOIS command reply.
4429 Affected file silcd/server.[ch].
4431 * Implemented the channel list sending in the WHOIS command reply
4432 in server and in the client.
4434 Implemented the channel list displaying on the user interface
4435 as well. Affected file silc/client_ops.c.
4437 * Added silc_channel_payload_parse_list to parse list of Channel
4438 Payloads. It returns SilcDList list of SilcChannelPayloads.
4439 Client for example can use this function to parse the list of
4440 channels it receives in the WHOIS command reply. The caller
4441 must free the list by calling silc_channel_payload_list_free.
4442 Affected files lib/silccore/silcchannel.[ch].
4444 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4446 * Added one new argument <user mode> to the WHOIS command reply
4447 to return the mode of the user in SILC. Updated the protocol
4450 Implemented it to the server and client.
4452 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4454 * Fixed the mode printing on the user interface on joining.
4455 Affected file silc/client_ops.c.
4457 * Implemented the UMODE command and user modes in general to the
4458 client library and to the user interface.
4460 * Implemented the UMODE command to the server.
4462 * The server now sends UNKNOWN_COMMAND error status if client sends
4463 unknown command. Affected file silcd/command.c.
4465 * All server commands now handle the command identifier the right
4466 way when sending the command reply to the client. The client can
4467 use to identify the command replies with the identifier.
4469 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4471 * Added silc_server_get_client_route to resolve the route to
4472 the client indicated by the client ID. Affected file is
4475 * Added silc_server_relay_packet as general function to relay
4476 packet to arbitrary destination. This deprecates functions
4477 like _send_private_message_key, _relay_notify etc. Affected
4478 file is silcd/packet_send.[ch].
4480 Removed silc_server_send_key_agreement,
4481 silc_server_send_private_message_key and
4482 silc_server_packet_relay_notify functions from the file
4483 silcd/packet_send.[ch].
4487 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4488 server. Affected file silcd/packet_receive.[ch].
4490 * Implemented the KILL command to the client. Implemented the
4491 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4492 Affected files lib/silcclient/command[_reply].c and
4493 lib/silcclient/client_notify.c. Implemented the KILL notify
4494 printing in the user inteface.
4496 * Fixed a lot silc_parse_nick memory leaks from the client
4497 library in the file lib/silcclient/command.c.
4499 * Changed the silc_server_send_notify_on_channels's `sender'
4500 argument from SilcSocketConnection to SilcClientEntry to
4501 check the sender as entry and not as connection object and not
4502 to send to the client provided as argument. The affected file
4503 is silcd/packet_send.[ch].
4505 * The notify packets that are destined directly to the client used
4506 to not to be processed by the server. Now changed that and the
4507 server processes all notify packets. After relaying the packet
4508 to the client the notify packet is processed in the server.
4510 * The silc_server_free_client_data now checks whether there is
4511 pending outgoing traffic for the client and purges the data to
4512 the network before removing the client entry.
4514 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4516 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4517 an client is killed from the SILC Network. Updated the protocol
4520 Added new function silc_server_send_notify_killed to the
4521 silcd/packet_send.[ch].
4523 * Added function silc_server_packet_relay_notify to relay notify
4524 packets that are destined directly to a client. In this case
4525 the server does not process the notify packets but merely relays
4526 it to the client. Affected file silcd/packet_send.[ch].
4528 Added also silc_server_packet_process_relay_notify to check
4529 whereto relay the notify. Affected file is
4530 silcd/packet_receive.[ch].
4532 * Implemented the KILL command to the server.
4536 * Added the backup schema desgined last fall to the protocol
4537 specs for everyone to see. The specification is in the
4538 *-spec-xx.txt draft and the packet type definitions for the
4539 backup routers is in *-pp-xx.txt draft. Thusly, added also
4540 new packet type SILC_PACKET_CELL_ROUTERS.
4542 * A big security problem in the implementation discovered. The
4543 signoff of an client did not cause new channel key generation
4544 which it of course should've done. The channel keys must be
4545 always re-generated when client leaves (or signoffs) the channel.
4546 The silc_server_remove_from_channels funtion now handles
4547 the channel key re-generation.
4549 * Added `sender' argument to the silc_server_send_notify_on_channels
4550 to not to send the client provided as argument. Affected file
4551 silcd/packet_send.[ch].
4553 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4555 * Implemented OPER and SILCOPER commands into the server and
4558 * Added silc_auth_verify and silc_auth_verify_data to verify
4559 the authentication directly from the authentication payload.
4560 It supports verifying both passphrase and public key based
4561 authentication. Affected file lib/silccore/silcauth.[ch].
4563 * Added `hash' field to the SilcIDListData structure. It is the
4564 hash negotiated in the SKE protocol. Affected file is
4567 * Slight redesigning of the SilcAuthPayload handling routines.
4568 Do not send SilcPKCS but SilcPublicKey as argument.
4570 * Implemented the public key authentication support to the
4571 serverconfig. The public key is loaded from the provided path
4572 and saved as authentication data to void * pointer. Thus,
4573 changed the unsigned char *auth_data to void *auth_data;
4575 * Fixed SHUTDOWN command to send the reply before the server
4576 is shutdown. :) Affected file silcd/command.c.
4578 * Fixed fatal bug in CONNECT command. The hostname was invalid
4579 memory and server crashed. Affected file silcd/command.c.
4581 * Fixed fatal bug in CLOSE command. The server_entry became
4582 invalid but was referenced later in the command. Affected file
4585 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4587 * Fixed fatal bug in failure packet handling. Server ignored
4588 the failure and thus crashed when it came.
4592 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4594 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4595 that the command may be executed only once in (about) 2 seconds.
4596 The old SILC_CF_LAG flag is same but allows command bursts up
4597 to five before limiting.
4599 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4600 server code. Various commands now includes the CF_LAG_STRICT
4601 flag to disallow any kind of miss-use of the command.
4603 * Fixed the silc_buffer_unformat to not to allocate any data
4604 if the length of the data is zero. It used to allocate the
4605 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4607 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4609 * Changed the format of AdminConnection configuration section
4610 in the server. Added username of the admin to the format.
4611 Affected files silcd/serverconfig.[ch].
4613 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4614 to return admin configuration data by host, username and/or
4617 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4619 * Implemented WHOWAS command to the server. Added the functions:
4621 silc_server_command_whowas_parse,
4622 silc_server_command_whowas_send_reply,
4623 silc_server_command_whowas_from_client and
4624 silc_server_command_whowas_from_server
4626 * Added <Client ID> argument to the WHOWAS command reply. Updated
4627 the protocol specs accordingly.
4629 * Implemented WHOWAS command and command_reply to the client
4632 Implemented the WHOWAS printing on the user interface.
4634 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4636 * Added new argument to the WHOWAS command reply, the real name.
4637 It is an optional argument. Updated the protocol specs.
4639 * Added SilcIDCacheDestructor callback that is registered when
4640 the SilcIDCache is allocated. The callback is called when
4641 an cache entry in the ID Cache expires, or is purged from the
4642 cache. Added into lib/silccore/idcache.[ch].
4644 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4645 to destruct the client entries when the cache entry expires.
4646 Other ID Cache's in server and in the client library ignores
4649 * If the ID Cache entry's `expire' field is zero then the entry
4650 never expires. Added boolean `expire' argument to the
4651 silc_idcache_add function in the lib/silccore/idcache.[ch].
4652 If it is TRUE the default expiry value is used.
4654 * Added silc_server_free_client_data_timeout that is registered
4655 when client disconnects. By default for 5 minutes we preserve
4656 the client entry for history - for WHOWAS command.
4658 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4660 * Added support to the server to enforce that commands are not
4661 executed more than once in 2 seconds. If server receives
4662 commands from client more frequently, timeout is registered
4663 to process the commands. Affected file silcd/command.c.
4664 Added new function silc_server_command_process_timeout.
4666 * Changed NICK_NOTIFY handling in client library to check that
4667 if the client's nickname was changed, so there is no need to
4668 resolve anything from the server.
4670 * Removed error printing from the WHOIS and IDENTIFY commands.
4671 If error occurs then it is ignored silently in the client library.
4672 The application, however, may map the received error to
4673 human readable error string. The application currently maps
4674 the NO_SUCH_NICKNAME error to string.
4676 * Made the command status message public to the application. Moved
4677 them from lib/silcclient/command_reply.c to
4678 lib/silcclient/command_reply.h. The application can map the
4679 received command status to the string with the
4680 silc_client_command_status_message function.
4682 * Added check to the server to check that client's ID is same
4683 as the Source ID in the packet the client sent. They must
4686 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4688 * Added dist-bzip hook to the Makefile.am to make bzip2
4689 compressed distributions.
4691 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * Server now enforces the maximum length for the nickname and
4694 the channel as protocol specification dictates. 128 bytes for
4695 nickname and 256 bytes for channel name.
4697 * Moved the WHOIS printing to the application. The client libary
4698 does not print out the WHOIS information anymore, the application
4699 must do it. Renamed silc_client_command_reply_whois_print to
4700 the silc_client_command_reply_whois_save.
4702 The client's idle time is also sent to the application now, and
4703 the idle is shown on screen.
4705 * Added silc_client_command_reply_identify_save to save the
4706 received IDENTIFY entries.
4708 * Do not check for channel private keys in message sending and
4709 reception if the channel does not have the PRIVKEY mode set.
4710 Affected file lib/silclient/client_channel.c.
4712 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4715 just surfaced after chaning the JOIN procedure.
4717 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Added silc_client_get_clients_by_list to get client entries
4720 from Client ID list, that is returned for example by JOIN
4721 and USERS command replies. The application should use this
4722 function for example when JOIN command reply is received to
4723 resolve the clients already on the channel (library does not
4724 do that anymore as USERS command reply is not used in the JOIN
4725 procedure anymore). Affected files lib/silcclient/silcapi.h and
4726 lib/silcclient/idlist.c.
4728 * JOIN command reply and USERS command reply returns now SilcBuffer
4729 pointers instead of unsigned char pointers when returning
4730 the client list and mode list.
4732 * Added <Client ID> argument to the JOIN command reply, mainly
4733 for the server to identify for which client the command was
4734 originally sent. Updated protocol specs accordingly.
4736 * Added SilcDlist private_key pointer to the SilcChannelEntry
4737 in the client to support the channel private keys. Affected
4738 file is lib/silcclient/idlist.h.
4740 * Added SilcChannelPrivateKey argument to the function
4741 silc_client_send_channel_message so that application can choose
4742 to use specific private ke if it wants to. If it is not provided,
4743 the normal channel key is used, unless private keys are set.
4744 In this case the first (key that was added first) is used
4745 as the encryption key.
4747 * Implemented the support for channel private key handling.
4748 Implemented the following functions:
4750 silc_client_add_channel_private_key,
4751 silc_client_del_channel_private_keys,
4752 silc_client_del_channel_private_key,
4753 silc_client_list_channel_private_keys and
4754 silc_client_free_channel_private_keys
4756 Affected file lib/silcclient/client_channel.c.
4758 * Added the support for the private keys in the channel message
4759 sending and encryption and in the message reception and
4760 decryption. Affected funtions are
4761 silc_client_send_channel_message and silc_client_channel_message.
4763 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4765 * Added SKE's key verify callback to the client library's
4766 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4768 * Removed the statement that server (or router) must send USERS
4769 command reply when joining to the channel so that the client
4770 knows who are on the channel. Instead, the client list and
4771 client's mode list is now sent in the JOIN command reply to the
4772 client who joined channel. This is better solution.
4774 * Added function silc_server_get_users_on_channel and function
4775 silc_server_save_users_on_channel to the silcd/server.[ch].
4777 * Removed function silc_server_command_send_users from the
4780 * Do not show topic on the client library anymore. The topic is
4781 sent in the command reply notify to the application and the
4782 application must show the topic now.
4784 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4786 * Added client searching by nickname hash into the IDENTIFY and
4787 WHOIS commands in the server as they were clearly missing from
4788 them. Affected file is silcd/command.c.
4790 * Fixed a bug in private message receiving in the client library.
4791 The remote ID was freed and it wasn't supposed, now it is
4794 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4796 * Minor fix to the channel payload; allocate the data area, as it
4797 needs to be of specific length.
4799 * If the key agreement port is zero then the operating
4800 system will define the bound port. Affected files are
4801 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4803 * Added new function silc_channel_payload_decrypt into the file
4804 lib/silccore/silcchannel.[ch].
4806 * Moved the channel message etc, check from silc_packet_decrypt
4807 to applications. The library calls now a generic
4808 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4809 when the packet is either normal or special. This was done to
4810 allow more wide range of checking that was not allowed when
4811 the code was in library. Now applications can do virtually any
4812 checks to the packet and return to the library the decision how
4813 the packet should be processed. Affected files are
4814 lib/silccore/silcpacket.[ch].
4816 Added silc_server_packet_decrypt_check to the server and
4817 silc_client_packet_decrypt_check to the client library.
4819 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4820 to send with specified source and destination information.
4822 * Channel message delivery between routers was broken after the
4823 channel key distribution was fixed earlier. The channel key
4824 was used be to distributed to other routers as well which is not
4825 allowed by the protocol. Now this is fixed and channel keys
4826 really are cell specific and the channel message delivery between
4827 routers comply with the protocol specification.
4829 * Fixed various commands in server to check also the global list
4830 for the channel entry and not just the local list. The affected
4831 file silcd/command.c.
4833 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4835 * Added assert()s to buffer formatting and unformatting routines
4836 to assert (if --enable-debug) when error occurs. Affected
4837 file: lib/silcutil/silcbuffmt.c.
4839 * Changed to auto-reconnect to check whether the remote host is
4840 router and register the re-connect timeout if it is. It used
4841 to check that whether we are normal server, but router must do
4842 auto-reconnect with another router as well. Affected file
4845 * Removed the [<key len>] option from CMODE command as the cipher
4846 name decides the key length, nowadays. See the defined ciphers
4847 from the protocol specification.
4849 * Added [<hmac>] option to the CMODE command to define the HMAC
4850 for the channel. Added SILC_CMODE_HMAC channel mode.
4852 * Added [<hmac>] option for the JOIN command so that user can
4853 select which HMAC is used to compute the MACs of the channel
4856 * Added Hmac field to the Channel Message Payload. The integrity
4857 of plaintext channel messages are now protected by computing
4858 MAC of the message and attaching the MAC to the payload. The
4859 MAC is encrypted. Now, it is clear that this causes some
4860 overhead to the size of the packet but rationale for this is that
4861 now the receiver can verify whether the channel message decrypted
4862 correctly and also when private keys are set for the channel the
4863 receiver can decrypt the packet with several keys and check from
4864 the MAC which key decrypted the message correctly.
4866 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4867 lib/silccrypt/silccipher.[ch].
4869 * Added silc_hash_len to return the digest length into the
4870 lib/silcrypt/silchash.[ch].
4872 * Rewrote parts of Silc Channel Payload interface in the
4873 lib/silccore/silcchannel.[ch]. The encode function now also
4874 encrypts the packet and parse function decrypts it.
4876 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4878 * Fixed a minor formatting bug in the SKE's key material processing.
4879 It actually might have processed the keys wrong way resulting
4882 * Redefined the mandatory HMAC algorithms and added new algorithms.
4883 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4884 and hmac-md5 truncated to 96 bits. The mandatory is now
4885 hmac-sha1-96. Rest are optional (including the one that used
4886 to be mandatory). Rationale for this is that the truncated HMAC
4887 length is sufficient from security point of view and can actually
4888 make the attack against the HMAC harder. Also, the truncated
4889 HMAC causes less overhead to the packets. See the RFC2104 for
4892 * Added new [hmac] configuration section. The SKE used to use
4893 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4894 is of course wrong. The official names that must be proposed in
4895 the SKE are the ones defined in the protocol specification
4896 (hmac-sha1-96 for example). The user can configure any hmac
4897 using any hash function configured in the [hash] section. At
4898 least, the mandatory must be configured.
4900 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4902 * Added HMAC list to the SKE proposal list. It has now both
4903 hash algorithm list and HMAC list. This makes the protocol
4904 incompatible with previous versions. The SKE now seems to work
4905 the way it is supposed to work, for the first time actually.
4907 * Defined plain Hash algorithms to the protocol specification.
4910 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4912 * Implemented support for key agreement packets into the server.
4913 Added functions silc_server_key_agreement and
4914 silc_server_send_key_agreement. Other than these functions,
4915 server has nothing to do with this packet.
4917 * Added support for private message key packets into the server.
4918 Added functions silc_server_private_message_key and
4919 silc_server_send_private_message_key.
4923 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4924 called in the protocol's final callback instead in the END
4925 protocol state. This makes a little more sense and in the same
4926 time in client we can use the same protocol routines for normal
4927 key exchange and to key agreement packet handling as well.
4929 * Added to both client's and server's KE protocol context the
4930 SilcSKEKeyMaterial pointer to save the key material. We will
4931 bring the key material to the protocol's final callback by doing
4932 this. The final callback must free the key material.
4934 * Added SKE's packet_send callback into client's KE protocol
4935 context so that the caller can choose what packet sending function
4936 is used. This way we can use different packet sending when
4937 doing normal SKE when doing key agreement packet handling (in
4938 the key agreement packet handling we do not want to encrypt
4941 * Implemented the responder side of the key agreement routines
4942 in the client. The client can now bind to specified port and
4943 accept incoming key negotiation. The key material is passed
4944 to the application after the protocol is over.
4946 * Implemented the processing of incoming Key Agreement packet
4947 in the client. Added function silc_client_key_agreement to
4950 * Implemented the intiator side of the key agreement routines
4951 in the client. The client can now initiate key agreement with
4952 another remote client. The key material is passed to the
4953 application after the protocol is over.
4955 * Created client_keyagr.c to include all the key agreement
4958 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4959 SILC_TASK_CALLBACK except that it is not static.
4961 * Created client_notify.c and moved the Notify packet handling
4962 from the client.[ch] into that file.
4964 * Created client_prvmsg.c and moved all private message and
4965 private message key routines from the client.[ch] into that file.
4967 * Create client_channel.c and moved all channel message and
4968 channel private key routines from the client.[ch] into that file.
4970 * Changed silc_client_get_client_by_id_resolve to resolve with
4971 WHOIS command instead of IDENTIFY command, in the file
4972 lib/silclient/idlist.c.
4974 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Implemented the SKE's responder side to the Client library.
4978 * When FAILURE is received to the protocol do not trust it
4979 blindly. Register a timeout to wait whether the remote closes
4980 the connection as it should do it, only after that process the
4981 actual failure. This was changed to both client and server.
4983 * Added client_internal.h to include some of the structures
4984 there instead of client.h in lib/silcclient/.
4986 * Added function silc_task_unregister_by_callback to unregister
4987 timeouts by the callback function.
4989 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4991 * Some "Incomplete WHOIS info" errors has been appearing on the
4992 log files. Took away the entry->userinfo check from WHOIS
4993 reply sending. The entry->userinfo is now " " if client did not
4994 provide one. I thought this was fixed earlier but something
4995 is wrong still. Let's see if the error still appears.
4997 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4999 * Fixed a minor bug in the login when the channel key is
5000 re-generated in the server. It used to generate the key in
5001 wrong order and thus caused problems in the channel traffic.
5003 * Fixed a minor bug in channel key distsribution after
5004 KICK command. The key was not sent to the router even though
5007 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5009 * Added silc_ske_process_key_material_data as generic routine
5010 to process any key material as the SILC protocol dictates. The
5011 function is used by the actual SKE library but can be used by
5012 applications as well. This relates to the private message keys
5013 and the channel private keys since they must be processed the
5014 same way the normal SILC session keys. The protocol dictates
5015 this. Affected files: lib/silcske/silcske.[ch].
5017 Added also silc_ske_free_key_material to free the
5018 SilcSKEKeyMaterial structure.
5020 * Defined silc_cipher_set_key function to set the key for
5021 cipher without using the object's method function. The affected
5022 files: lib/silccrypt/silccipher.[ch].
5024 * Implemented silc silc_client_add_private_message_key,
5025 silc_client_add_private_message_key_ske,
5026 silc_client_del_private_message_key,
5027 silc_client_list_private_message_keys and
5028 silc_client_free_private_message_keys functions in the
5031 Added functions silc_client_send_private_message_key to send
5032 the Private Message Key payload and silc_client_private_message_key
5033 to handle incoming Private Message Key payload.
5035 * Added Cipher field to the Private Message Key payload to set
5036 the cipher to be used. If ignored, the default cipher defined
5037 in the SILC protocol (aes-256-cbc) is used.
5039 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5041 * Removed lib/silcclient/ops.h file.
5043 Redefined parts of the SILC Client Library API. Created new
5044 file silcapi.h that deprecates the ops.h file and defines the
5045 published Client Library API. Defined also private message key
5046 API and channel private key API into the file.
5048 This is the file that the application must include from the
5049 SILC Client Library. Other files need not be included by
5050 the application anymore.
5052 * Added new key_agreement client operation callback and also
5053 defined the Key Agreement library API for the application.
5055 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5058 is used by clients to request key negotiation between another
5059 client in the SILC network. If the negotiation is started it
5060 is performed using the SKE protocol. The result of the
5061 negotiation, the secret key material, can be used for example
5062 as private message key.
5064 Implemented the Key Agreement payload into the files
5065 lib/silccore/silauth.[ch].
5067 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5069 * Redefined ciphers for the SILC protocol. Added some new ciphers
5070 and defined the key lengths for the algorithms. Changed the
5071 code accordingly. The default key length is now 256 bits.
5073 * Fixed SKE key distribution function silc_ske_process_key_material
5074 when the key length is more than 128 bits. The default key
5075 length in SILC is now 256 bits.
5077 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5078 to indicate unsupported algorithm.
5080 * Renamed rijndael.c to aes.c and all functions as well.
5082 * Fixed a long standing channel key setting bug in client library.
5083 Weird that it has never surfaced before.
5085 * Fixed bug in channel deletion. If the entire channel is removed
5086 then it must also delete the references of the channel entry
5087 from the client's channel list as the client's channel entry and
5088 the channel's client entry share same memory.
5090 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5092 * Implemented CONNECT and SHUTDOWN commands in the client.
5094 * Implemented CLOSE command to the client.
5096 * Added the function silc_idlist_find_server_by_name into the
5097 files silcd/idlist.[ch].
5099 Added the function silc_idlist_find_server_by_conn into the
5100 files silcd/idlist.[ch].
5102 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5104 * DIE command was renamed to SHUTDOWN. Updated the both code
5107 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5108 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5110 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5113 * Added function silc_server_create_connection function to create
5114 connection to remote router. My server implementation actually
5115 does not allow router to connect to normal server (it expects
5116 that normal server always initiates the connection to the router)
5117 so the CONNECT command is only good for connecting to another
5120 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5122 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5123 or some other client was kicked from the channel.
5125 Implemented the handling of the notify type to both client
5128 Implemented silc_server_send_notify_kicked to send the KICKED
5129 notify. It is used to send it to the server's primary router.
5131 * Implemented the KICK command into server and client.
5133 * Added `query' argument to the silc_idlist_get_client function
5134 to indicate whether to query the client from server or not if
5137 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5138 to indicate that the client is not channel founder.
5142 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5144 * Removed the rng context from SilcPacketContext structure and
5145 changed that the packet routine uses the Global RNG API.
5147 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5149 * Added support for quit message that client can "leave" on the
5150 channel when it quits the SILC. It is ditributed inside the
5151 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5153 Added silc_server_free_client_data that will take the
5154 signoff message as argument.
5156 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5158 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5160 * Updated parts of the protocol specification to keep it up
5163 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5165 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5166 payloads in one packet.
5168 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5169 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5170 use now the new List flag.
5172 * Also deprecated the following packet types: REPLACE_ID,
5173 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5175 * Added list support for Notify packet in server.
5177 * Added silc_server_send_notify_channel_change to send the
5178 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5179 the silc_server_send_replace_id.
5181 * Added silc_server_send_notify_nick_change to send the
5182 NICK_CHANGE notify type. Deprecates the function
5183 silc_server_send_replace_id.
5185 * Added silc_server_send_notify_join to send the JOIN notify type.
5186 Deprecates the function silc_server_send_new_channel_user.
5188 * Added silc_server_send_notify_leave to send LEAVE notify type.
5189 Deprecates the function silc_server_send_remove_channel_user.
5191 * Added silc_server_send_notify_cmode and
5192 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5193 types. Deprecates the silc_server_send_set_mode function.
5195 * Added SERVER_SIGNOFF notify type to indicate that server has
5196 quit. This means that all clients on the channel from that
5197 server will drop. This can be also used when netsplit happens.
5199 Deprecated REMOVE_ID packet type since it is not needed anymore
5202 Added silc_server_send_notify_server_signoff to send the
5203 SERVER_SIGNOFF notify type. Deprecates the function
5204 silc_server_send_remove_id.
5206 Added also silc_server_send_notify_signoff to send the
5207 SIGNOFF notify type.
5209 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5210 SILC protocol from this day on. Changed the protocol
5211 specification as well.
5213 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5214 notify type. It is used between routers to notify about
5215 topic changes on a channel.
5217 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5220 * Partly updated the protocol specification to comply with the
5221 changes now made. It is still though a bit outdated.
5223 * The JOIN notify type now takes one extra argument <Channel ID>.
5224 The packet used to be destined to the channel but now the
5225 JOIN type may be sent as list thus it is impossible to
5226 destine it to any specific channel. By adding this argument
5227 it is again possible.
5229 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5231 * Added CREDITS file. The CHANGES and CREDITS file will appear
5232 in the distribution as well.
5234 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5236 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5237 types in the server's silcd/packet_receive.c.
5239 * Implemented CMODE and CUMODE to work in router environment.
5241 * Fixed minor encoding and decoding buglet from the
5242 lib/silccore/silcmode.c.
5244 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5247 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5249 * Changed all SilcConfigServer* and silc_config_server* to
5250 SilcServerConfig* and silc_server_config*, respectively.
5253 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5255 * Associated the ID (client or server ID) to the Authentication
5256 Payload to avoid any possibility of forging. Updated the
5257 protocol specification and the code accordingly.
5259 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5261 * The RSA key length is now save to the RsaKey context in the
5262 key generation process in lib/silccrypt/rsa.c. The key length
5263 is now used to figure out the maximum size of the block allowed
5264 to be encrypted/signed.
5266 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5267 is equivalent to the silc_mp_mp2bin but does not allocate any
5270 * Changed silc_mp_mp2bin API to take length argument. If it is
5271 non-zero then the buffer is allocated that large. If zero, then
5272 the size is approximated using silc_mp_sizeinbase, which however
5275 * Created Global RNG API which is global RNG that application can
5276 initialize. After initializing, any routine anywhere in the
5277 code (including library) can use RNG without allocating a new
5278 RNG object. This was done to allow this sort of use of the
5279 RNG in code that has no chance to allocate RNG object. All
5280 applications currently allocate this and many routines in the
5281 library use this. Affected file lib/silccrypt/silcrng.[ch].
5283 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5284 it to use the Global RNG API.
5286 * Defined Authentication Payload into protocol specification that
5287 is used during SILC session to authenticate entities. It is
5288 used for example by client to authenticate itself to the server
5289 to obtain server operator privileges.
5291 Implemented this payload into the lib/silccore/silcauth.[ch].
5292 Implemented also routines for public key based authentication
5293 as the new protocol specification dictates.
5295 Moved definitions of different authentication methods from
5296 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5298 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5299 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5300 silc_pkcs_verify_with_hash functions into the file
5301 lib/silccrypt/silcpkcs.[ch].
5303 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5305 * The client entry's userinfo pointer must be always valid.
5306 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5307 will fail since it requires the userinfo. Now, the userinfo
5308 is allocated as "" if actual userinfo does not exist. Actually,
5309 it must exist and it is totally Ok to drop client connections
5310 that does not announce the userinfo. However, we will make
5311 this workaround for now.
5313 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5314 to return the remote port by socket.
5316 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5318 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5319 SILC_SERVER_PENDING_EXEC and added an new macro
5320 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5321 data or when error occurs while processing the pending command.
5323 Added new argument `destructor' into silc_server_command_pending
5324 and to the SilcServerCommandPending object. This destructor is
5325 now called after calling the pending callback or if error occurs
5326 immediately. If error occurs the actual pending callback won't
5327 be called at all - only the destructor. The destructor may be
5328 NULL if destructor is not needed.
5330 All this applies for client library code as well. Similar
5331 changes were made there as well for the pending commands.
5333 In the client, the application must now allocate the
5334 SilcClientCommandContext with the silc_client_command_alloc
5337 * Added reference counter to the SilcServerCommandContext. Added
5338 function silc_server_command_alloc and silc_server_command_dup
5341 Same type of functions added to the client library for the same
5344 * Removed the cmd_ident from IDListData away since it is now
5345 global for all connections. It is the command identifier used
5346 in command sending and with pending commands. The affected file
5349 * Added reference counter to the SilcSocketConnection objecet to
5350 indicate the usage count of the object. The object won't be
5351 freed untill the reference counter hits zero. Currently only
5352 server uses this, and client ignores it. The client must be
5353 set to use this too later. The affected files are
5354 lib/silccore/silcsockconn.[ch]. Added also the function
5355 silc_socket_dup to increase the reference counter.
5357 This was mainly added because it is possible that the socket
5358 is removed underneath of pending command or other async
5359 operation. Now it won't be free'd and proper DISCONNECTING
5360 flags, etc. can be set to avoid sending data to connection that
5361 is not valid anymore.
5363 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5364 the connection. After that it sets SILC_SET_DISCONNECTED.
5365 It is, however, possible that the socket data is not still freed.
5366 The silc_server_packet_process now checks that data is not
5367 read or written to connection that is DISCONNECTED. The socket
5368 get's freed when the reference counter hits zero.
5370 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5372 * Changed the client operation API: channel_message operation's
5373 `sender' is now the client entry of the sender, not the nickname
5374 and the `channel' is the channel entry, not the channel name.
5376 In the private_message operation the `sender' is now also the
5377 client entry of the sender not the nickname.
5379 Affected file is lib/silcclient/ops.h and all applications
5380 using the client operations.
5382 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5384 * Moved the calling of ops->connect() from connect_to_server_final
5385 into receive_new_id functin since that is the point when the
5386 client is actually allowed to send traffic to network. The
5387 affected file is lib/silcclient/client.c.
5389 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5391 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5392 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5393 (if needs broadcasting) instead of broadcasting the packets one
5394 by one which would make a burst in the network traffic.
5396 * Added `broadcast' argument to the functions in silcd/server.[ch]
5397 silc_server_create_new_channel[_with_id] to indicate whether
5398 to send New Channel packet to primary router.
5400 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5402 * Added new function into the silcd/server.[ch] files:
5403 silc_server_create_new_channel_with_id to create new channel with
5404 already existing Channel ID.
5406 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5407 lib/silccore/silcpacket.h. This packet is used t send list of
5408 Set Mode payloads inside one packet. Server uses this to set
5409 the modes for the channels and clients on those channels, that it
5410 announced to the router when it connected to it. The protocol
5411 specification has been updated accordingly.
5413 * The silc_server_new_channel did not handle the packet coming
5414 from normal server as it normally does not send that. However,
5415 when it announces its channels it does send it. Implemented
5416 the support for that.
5418 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5419 into the file lib/silccore/id.h.
5421 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5423 * Fixed memory leaks in the functions silc_idlist_del_client,
5424 silc_idlist_del_channel and silc_idlist_del_server in the file
5425 silcd/idlist.c. All of those leaked like a sieve.
5427 * Fixed some small memory leaks in the client's function
5428 silc_client_notify_by_server.
5430 * Added functions into silcd/server.c: silc_server_announce_clients,
5431 silc_server_announce_channels and silc_server_announce_server.
5432 These functions are used by normal and router server to announce
5433 to its primary router about clients, channels and servers (when
5434 router) that we own. This is done after we've connected to the
5437 These functions effectively implements the following packet types:
5438 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5439 and SILC_PACKET_NEW_ID_LIST.
5441 * Added new functions into the silcd/packet_receive.[ch]:
5442 silc_server_new_id_list, silc_server_new_channel_list and
5443 silc_server_new_channel_user_list to handle the incoming
5444 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5446 * Added support of changing Channel ID in the function
5447 silc_server_replace_id. If the server that announces a channel
5448 to the router already exists in the router (with same name but
5449 with different Channel ID), router is responsible to send
5450 Replace ID packet to the server and force the server to change
5451 the Channel ID to the one router has.
5453 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5454 client that the Channel ID has been changed by the router. The
5455 normal server sends this to the client. Client must start using
5456 the new Channel ID as the channel's ID.
5458 Implemented handling of this new type into lib/silcclient/client.c
5459 into the function silc_client_notify_by_server.
5461 * Added new function silc_idlist_replace_channel_id into the files
5462 silcd/idlist.[ch] to replace the Channel ID.
5464 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5466 * Call silc_server_command_identify_check always when processing
5467 the IDENTIFY command in silcd/command.c
5469 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5471 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5472 send keepalive packets. The packet can be sent by clients,
5473 servers and routers.
5475 Added function silc_socket_set_heartbeat into the file
5476 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5477 If not set, the heartbeat is not performed. The actual
5478 heartbeat is implemented in the low level socket connection
5479 library. However, application is responsible of actually
5482 Added silc_server_send_heartbeat to send the actual heartbeat
5483 packet into silcd/packet_send.[ch]. Server now performs
5484 keepalive with all connections.
5486 * Added silc_task_get_first function into lib/silcutil/silctask.c
5487 to return the timeout task with shortest timeout. There was a bug
5488 in task unregistration that caused problems. TODO has been
5489 updated to include that task system must be rewritten.
5491 * The client library will now resolve the client information when
5492 receiving JOIN notify from server for client that we know but
5493 have incomplete information.
5495 * Rewrote parts of silc_server_remove_from_channels and
5496 silc_server_remove_from_one_channel as they did not remove the
5497 channel in some circumstances even though they should've.
5499 * Encryption problem encountered in server:
5501 The LEAVE command used to send the Channel Key packet to the
5502 router immediately after generating it. However, the code
5503 had earlier sent Remove Channel user packet but not immediately,
5504 ie. it was put to queue. The order of packets in the router
5505 was that Channel Key packet was first and Remove Channel User
5506 packet was second, even though they were encrypted in the
5507 reverse order. For this reason, MAC check failed. Now, this
5508 is fixed by not sending the Channel Key packet immediately but
5509 putting it to queue. However, this is more fundamental problem:
5510 packets that are in queue should actually not be encrypted
5511 because packets that are sent immediately gets encrypted
5512 actually with wrong IV (and thus MAC check fails). So, packets
5513 that are in queue should be encrypted when they are sent to
5514 the wire and not when they put to the queue.
5516 However, the problem is that the current system has not been
5517 designed to work that way. Instead, the packet is encrypted
5518 as soon as possible and left to the queue. The queue is then
5519 just purged into wire. There won't be any fixes for this
5520 any time soon. So, the current semantic for packet sending
5523 o If you send packet to remote host and do not force the send
5524 (the packet will be in queue) then all subsequent packets to the
5525 same remote host must also be put to the queue. Only after the
5526 queue has been purged is it safe again to force the packet
5529 o If you send all packets immediately then it safe to send
5530 any of subsequent packets through the queue, however, after
5531 the first packet is put to queue then any subsequent packets
5532 must also be put to the queue.
5534 Follow these rules and everything works fine.
5536 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * Added new function silc_server_remove_clients_by_server to
5539 remove all client entries from ID list when the server connection
5540 is lost. In this case it is also important to invalidate all
5541 client entires as they hold the invalid server entry. This
5542 fixes fatal bug when server has lost connection and will reconnect
5545 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5547 * Made some sanity checks to silc_server_daemonise like to check
5548 whether the requested user and group actually exists.
5550 * Added sanity check to SKE's silc_ske_responder_finish to check
5551 that the public and private key actually is valid.
5553 * Invalidate the client's nickname when receiving Replace ID
5554 packet and the Client ID is being replaced. This means that the
5555 server will query the nickname if someone needs it (client)
5558 * Sort the ID Cache in client library when the ID Cache data
5559 has changed (needs sorting).
5561 * Do not allow for SILC client to create several connections to
5562 several servers. The client does not support windows right now
5563 and generating multiple connections causes weird behaviour.
5565 Irssi-silc client does support windows and can handle several
5566 connections without problems, see: www.irssi.org and SILC plugin.
5568 * Fixed some places where client was added to the IDList. The
5569 rule of thumb is following (in order to get everything right):
5570 If the client is directly connected local client then the
5571 `connection' argument must be set and `router' argument must be
5572 NULL to silc_idlist_add_client function. If the client is not
5573 directly connected client then the `router' argument must
5574 bet set and the `connection' argument must be NULL to the
5575 silc_idlist_add_client function.
5577 * The funtion silc_server_packet_send_local_channel actually did
5578 not check whether the client was locally connected or not. It
5579 does that now. Fixed a bug related to LEAVE command.
5581 * Fixed Remove Channel User payload parsing bug in server's
5582 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5584 * The server's silc_server_save_channel_key now checks also the
5585 global ID list for the channel as it might not be in the local
5586 list. Fixed a bug related to LEAVE command.
5588 * Is this the end of the [<unknown>] buglet that has been lurking
5589 around for a long time? A little for loop fix in server's
5590 silc_server_command_whois_parse that is used by both IDENTIFY
5591 and WHOIS command. At least, this was a clear bug and a cause
5592 of one type of [<unknown>] buglet.
5594 * WHOIS and IDENTIFY commands call the function
5595 silc_server_command_[whois/identify]_check function even if
5596 we are not router server.
5598 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5600 * Added --with-gmp configuration option. If set the GMP
5601 is always compiled in the SILC source tree. If not set then
5602 it is checked whether the system has the GMP3 installed. If
5603 it has then the GMP won't be compiled (the system's headers
5604 and library is used), if it doesn't have it then the GMP is
5605 compiled in the SILC source tree.
5607 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Changed RSA private exponent generation to what PKCS #1
5610 suggests. We try to find the smallest possible d by doing
5611 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5612 not security fix but optimization.
5614 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5616 * Added new config entry [Identity] to fork the server and run
5617 it as specific user and group. A patch from Bostik.
5619 * Imported Dotconf configuration library into lib/dotconf.
5620 This will be used to create the SILC configuration files later.
5621 It will appear in the distsribution after this commit.
5623 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5625 * A big code auditing weekend happening. Auditing code for
5626 obvious mistakes, bugs and errors. Also, removing any code
5629 Removed files for being obsolete:
5631 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5632 inline in the file lib/silcutil/silcbuffer.h)
5634 o lib/silcutil/silcbufutil.c (the header has inline versions)
5636 Changed code to fix possible error conditions:
5638 o The buffer formatting routines now check that the destination
5639 buffer really has enough space to add the data. This applies for
5640 both buffer formatting and unformatting
5641 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5642 unformatting was changed to accomodate following rules:
5643 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5644 sent to the function while XXX_*STRING will not allocate or copy
5645 the data into the buffer. Instead it sets the pointer from the
5646 buffer into the pointer sent as argument (XXX_*STRING used to
5647 require that the pointer must be allocated already). This change
5648 makes this whole thing a bit more consistent and more optimized
5649 (note that the data returned in the unformatting with XXX_*STRING
5650 must not be freed now). The routines return now -1 on error.
5652 o Tried to find all code that use buffer_format and buffer_unformat
5653 and added return value checking to prevent formatting and
5654 especially unformatting errors and possible subsequent fatal
5657 o Changed ske->x and ske->KEY to mallocated pointers in
5658 lib/silcske/silcske.h. Fixed possible data and memory leak.
5660 o Added return value checking to all *_parse* functions. Fixed
5661 many memory leaks as well.
5663 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5664 so that buffer overflows would not happen. All code now also
5665 checks the return value as it can fail.
5667 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5669 * Added reconnection support to server if the normal server looses
5670 its connection to the router (for example if router is rebooted).
5671 The server performs normal reconnection strategy implemented
5672 to the server. Affected file silcd/server.c.
5674 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Added new packet type SILC_PACKET_SET_MODE that is used to
5677 distribute the information about changed modes (for clients,
5678 channels and clients channel modes) to all routers in the
5679 network. Updated the protocol specification accordingly.
5681 Added functions into silcd/packet_send.c and
5682 silcd/packet_receive.c: silc_server_send_set_mode,
5683 silc_server_set_mode.
5685 Added new files silcmode.[ch] into lib/silccore that implements
5686 the encoding and decoding of Set Mode Payload. Added new type
5687 SilcSetModePayload. Moved the definitions of different modes
5688 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5690 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5692 * Oops, a little mistake in server's connection authentication
5693 protocol. The protocol is not ended with FAILURE but with
5694 SUCCESS if the authentication is Ok. :) Affected file is
5697 * Implemented NICK_CHANGE notify handling in server in the file
5698 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5699 the local clients on the channel. After the changing nickname
5700 in router environment snhould work and the [<unknown>] nickname
5701 should appear no more.
5703 The silc_server_replace_id function that receives the Replace ID
5704 payload now sends the NICK_CHANGE notify type also in the file
5705 silcd/packet_receive.c
5707 * Changed WHOIS and IDENTIFY command to support the maximum amount
5708 of arguments defined in protocol specs (3328 arguments). This
5709 fixed a bug that caused problems when there were more than three
5712 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5714 * Added extra parameter, command identifier, to the
5715 silc_client_send_command so that explicit command identifier
5718 Changed that ID list routines uses specific command identifier
5719 when sending WHOIS/IDENTIFY requests to the server so that they
5720 can be identified when the reply comes back.
5722 Affected files lib/silcclient/command.[ch],
5723 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5725 * Added `sender' argument to silc_server_packet_send_to_channel
5726 to indicaet the sender who originally sent the packet to us
5727 that we are now re-sending. Ignored if NULL. Affected file
5728 silcd/packet_send.[ch].
5730 * Added some server statistics support in silcd/server_internal.h
5731 SilcServerStatistics structure and around the server code. Also
5732 send some nice statistics information when client is connecting
5735 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5737 * Fixed channel ID decoding in server's JOIN command reply in
5738 silcd/command_reply.c
5740 * Fixed braodcasting of replace ID payload to not to send it if
5741 we are standalone server in silcd/packet_receive.c.
5743 * Fixed all channel message sending routines to not to send
5744 packets to clients that has router set, since they are routed
5745 separately in the same function earlier. Affects file
5746 silcd/packet_send.c and all channel packet sending functions.
5748 * In USERS reply, res_argv[i] are not allocated, the table
5749 is allocated. Thus changed that free the table, not its
5752 * In server's whois_check and identify_check if the client is
5753 locally connected do not send any WHOIS commands - they are not
5756 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5758 * Fixed some minor bugs in client when sending WHOIS command. The
5759 arguments was in wrong order.
5761 * Removed statis function add_to_channel from server in
5762 silcd/command.c that was previously used with the joining but
5765 * Tested USERS command in router environment successfully with two
5766 routers, two servers and two clients.
5768 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5770 * Reorganized the USERS command and command reply in client library
5771 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5772 When the command is given by user we register a pending command
5773 callback that will reprocess the command after the reply has been
5774 received from the server. When reprocessing the packet we then
5775 display the information. Thus, the USERS information is displayed
5776 now in the command callback instead of in the command reply
5777 callback. The processing of the command is same as previously
5778 when server has sent the command reply in the JOINing process.
5780 * Added to USERS command in silcd/command_reply.c to join the client,
5781 we didn't use to know about, to the channel after we've created
5782 a client entry for it. Also, for clienet we did know already still
5783 check whether it is on the channel or not and add it if not.
5785 * Removed silc_server_command_join_notify as the function and its
5788 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5790 * Changed the client's pending command handling to the same as the
5791 server's pending command handling. It is also now possible to
5792 execute command reply functions from other command reply
5793 function as the function callbacks for commands and command
5794 replies are one and same. The pending commands are not static
5795 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5796 in client connection context. Thus, pending commands are server
5797 connection specific as it is convenient.
5799 Changed the function silc_client_command_pending and
5800 silc_client_command_pending_del and added new function
5801 silc_client_command_pending_check. Removed the
5802 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5805 * Added cmd_ident, current command identifier, to the client
5806 connection context in lib/silcclient/client.h to keep track on
5807 command identifiers used in command sending. Client's command reply
5808 function handling now supports the mandatory command identifiers.
5810 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5811 funtions in client to fully support pending command callbacks.
5813 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5814 as one of the arguments to the application in the command reply
5817 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5818 before first releasing SILC but came back. Now it is removed again
5819 and should come back nomore. The FORWARDED flag was used only
5820 by the JOINing procedure by forwarding the command packet to router.
5821 Now, the JOINing procedure has been changed to more generic (due
5822 to various router environment issues) and FORWARDED is not needed
5823 anymore for anything. The protocol specification is yet to be
5826 Now, removed silc_server_packet_forward from server and the flag
5827 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5829 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5831 * Renamed NAMES command to USERS command. The NAMES was named that
5832 due to historical reasons. Now it is renamed. Also, rewrote
5833 parts of the USERS command. The nickname list is not sent anymore
5834 by the server. Only Client ID and mode lists are sent in the USERS
5835 command. Changed this also to the protocol specification.
5837 The client now resolves the names and stuff after it receives
5838 the USERS list from the server when joining to the channel.
5840 * WHOIS and IDENTIFY commands has been changed to support multiple
5841 Client ID's per command. One can now search for multiple users
5842 in the network by sending only one WHOIS or IDENTIFY command.
5843 Changed the code and the protocol specifications.
5845 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5846 uses silc_server_command_whois_parse to parse the request. */
5848 * If normal server, do not parse the WHOIS and IDENTIFY requests
5849 before sending it to the router. Saves some time.
5851 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5853 * Fixed JOIN command on client library. Wrong number of arguments
5854 used to crash the client.
5856 * Added silc_server_channel_has_global function to check whether
5857 channel has global users or not.
5859 * Added silc_server_channel_has_local function to check whether channel
5860 has locally connected clients on the channel.
5862 * The silc_server_remove_from_one_channel now checks whether the
5863 channel has global users or not after given client was removed from
5864 the channel. It also checks whether the channel has local clients
5865 on the channel anymore. If it does not have then the channel entry
5866 is removed as it is not needed anymore.
5868 * The silc_server_notify now checks on JOIN notify whether the joining
5869 client is one of locally connected or global. If it is global then
5870 the channel has now global users on the channel and that is marked
5871 to the channel entry. Also, it now saves the global client to
5872 global list who is joining and JOINs it to the channel. This is
5873 for normal server, that is.
5875 Changed silc_server_send_notify_on_channel,
5876 silc_server_packet_relay_to_channel and
5877 silc_server_packet_send_to_channel check if we are normal server
5878 and client has router set (ie. global client) do not send the
5879 message to that client, as it is already routed to our router.
5881 * Implemented LEAVE notify type handling in silc_server_notify
5884 * Tested LEAVE command in router environment successfully. Tested
5885 with two routers, two servers and two clients.
5889 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5891 * Implemented SIGNOFF notify type handling in silc_server_notify
5894 * silc_server_remove_id now removes the client entry from all channels
5895 it has joined and thusly sends SIGNOFF notify type.
5897 * Rewrote the NAMES list generation in server by removing two excess
5898 loops. The lists are created now inside one loop.
5900 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5902 * silc_server_remove_channel_user checks now also global list
5903 for channel and client.
5905 * silc_server_new_channel_user checks now both local and global
5906 list for channel and client. Fixed a bug in client id decoding.
5907 Used to decode wrong buffer.
5909 * silc_server_channel_message checks now both local and global
5910 list for channel entry.
5912 * Tested channel joining (hence JOIN) in router environment
5913 successfully. Tested with two routers, two servers and two
5916 * Tested channel message sending in router environment successfully.
5918 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5920 * Added silc_server_save_channel_key into server.[ch] to save the
5921 received channel key in Channel Key payload processing. It is
5922 also used in JOIN command reply handling.
5924 Equivalent function silc_client_save_channel_key added into
5925 client.[ch] into client library.
5927 * Changed JOIN command reply to send information whether the channel
5928 was created or not (is existing already) and the channel key
5929 payload. Changed protocol specs accordingly.
5931 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5932 the request was sent by ID and not by nickname. Crashed on
5935 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5937 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5938 now correctly save the received data.
5940 * silc_server_free_sock_user_data now notifies routers in the
5941 network about entities leaving the network.
5943 At the same time implemented functions silc_server_remove_id
5944 and silc_server_send_remove_id to receive and send REMOVE_ID
5945 packets. The packet is used to notify routers in the network
5946 about leaving entities. The ID removed will become invalid in
5949 * Added function silc_idlist_del_server into server. Removes and
5950 free's server entry from ID list.
5952 * silc_server_private_message function now checks, if we are router,
5953 that the destination ID really is valid ID, naturally.
5955 * In router when NEW_ID packet is received (for new client) the
5956 hash of the Client ID is saved in the ID Cache but the
5957 client->nickname is set to NULL, instead of putting the hash
5960 IDENTIFY command now also checks that client->nickname must be
5961 valid. If it is not if will request the data from the server who
5962 owns the client. Added new function
5963 silc_server_command_identify_check.
5965 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5966 to set the command to already allocated Command Payload.
5968 * Tested private message sending in router environment with two
5969 routers, two servers and two clients. Fixed minor bugs and now
5972 * Fixed segfault from client's NAMES command. Used to crash if
5975 * Forwarded packets must not be routed even if it is not destined
5976 to the receiver. Changed server code comply with this.
5978 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5980 * Added `require_reverse_mapping' boolean value to ServerParams
5981 structure. If TRUE (not default) the server will require that
5982 the connecting host has fully qualified domain name.
5984 If the reverse mapping is not required and hostname could not be
5985 found the IP address is used as hostname.
5987 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5989 * Implemented version string checking to both client and server.
5990 The check is incomplete currently due to the abnormal version
5991 strings used in development version of SILC.
5993 * Changed all command functions in server to use the new
5996 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5998 * Changed char *data to unsigned char *data in ID Cache system to
5999 support binary data as ID Cache data. Changed code to support
6000 binary data in lib/silccore/idcache.c.
6002 * Renamed silc_server_packet_relay_command_reply to
6003 silc_server_command_reply as it is normal packet receiving
6004 function. Rewrote the function to accept command replys for
6005 servers and not only for clients.
6007 * Mark remote router always as registered server if we are connecting
6008 to it. Otherwise, commands sent by the router to us are ignored.
6010 * All ID List find routines now returns the ID Cache Entry pointer
6011 as well if requested.
6013 * WHOIS command works now in router environment, tested with two
6014 routers, two servers and two clients.
6016 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6017 in router environment (as it is almost equivalent to WHOIS) but
6018 hasn't been tested thoroughly. Added new functions:
6020 silc_server_command_identify_parse
6021 silc_server_command_identify_send_reply
6022 silc_server_command_identify_from_client
6023 silc_server_command_identify_from_server
6025 * Disabled route cache adding because adding two different ID's with
6026 same IP replaces the old cache entry thus giving wrong route.
6027 The entry->router->connection is always the fastest route anyway
6028 so route cache may not be needed. Of course, new routes maybe
6029 established after receiving the ID when the entry->router->connection
6030 might not be anymore the most optimal.
6032 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6034 * Add route cache for received ID for fast routing.
6036 * Added silc_server_packet_route to route received packet on router
6037 that is not destined to us.
6039 * Renamed silc_server_get_route to silc_server_route_get.
6041 * Added id_string and id_string_len fields into SilcServer to
6042 include encoded ServerID for fast comparing without excess
6043 encoding of the ID's.
6045 * Cleaned up WHOIS command on server side. Added following static
6048 silc_server_command_whois_parse
6049 silc_server_command_whois_check
6050 silc_server_command_whois_send_reply
6051 silc_server_command_whois_from_client
6052 silc_server_command_whois_from_server
6054 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6055 arguments in command replies. All command functions should be
6056 updated to use this macro.
6058 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6060 * Minor typo fixes on command reply handling on server.
6062 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6064 * Added silc_server_command_add_to_channel internal routine to add
6065 the client to the channel after router has created the channel and
6066 sent command reply to the server.
6068 * Added generic silc_server_send_command to send any command from
6071 * Use static buffer with ID rendering instead of duplicating data.
6073 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6075 * Fixed a channel user mode bug when joining to a channel server gave
6076 everybody channel founder rights, oops.
6078 * We mark ourselves as the router of the incoming server connection
6079 if we are router ourselves. This way we can check in some packet
6080 sending functions whether it is locally connected server. For
6081 incoming router connections we put NULL.
6083 * For router sending packets locally means now always sending the
6084 packet cell wide; to local clients and local servers. For normal
6085 server sending packet locally means sending it to only local
6088 * Fixed the JOIN command to really work in router environment. If the
6089 channel is created it is always created by the router. Router is
6090 also responsible of making the initial joining to the channel,
6091 sending JOIN notify to the sending server and distributing
6092 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6093 does not exist server doesn't do anything else but forward the
6094 command to the router which performs everything.
6096 * Added silc_server_send_channel_key function to send the Channel Key
6099 * Added silc_server_create_channel_key to create new channel key. The
6100 channel key is now re-generated everytime someone joins or leaves
6101 a channel, as protocol dictates. Note: channel->key_len is the
6104 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6106 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6107 packet_receive.[ch] to separate packet sending and receiving
6108 routines. The server.[ch] now includes everything else including
6109 actual packet processing (writing and reading data) and other
6112 Renamed silc_server_private_message_send_internal to
6113 silc_server_send_private_message. The routine is still though
6114 used only to relay private messages as server does not send
6115 private messages itself.
6117 Renamed silc_server_new_channel to silc_server_create_new_channel
6118 and added new function sicl_server_new_channel that handles the
6119 incoming New Channel packet. Added also new sending function
6120 silc_server_send_new_channel to send New Channel Payload.
6122 * Added new function silc_server_notify to process incoming notify
6123 packet to the server/router. Server may then relay the notify
6124 to clients if needed.
6126 * Added new function silc_server_new_channel_user to process incoming
6127 New Channel User packet. Router will redistribute the packet and
6128 send JOIN notify to its local clients and locally connected servers
6129 if needed. Normal server will send JOIN notify to its local client
6130 on same channel when received this packet. Added also corresponding
6131 sending function silc_server_send_new_channel_user to sent the
6134 * Added boolean route argument to send_notif_to_channel and
6135 packet_send_to_channel functions to attempt to route the packet
6136 if it is TRUE and send only locally if it is FALSE.
6138 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * silc_server_replace_id now broadcasts the received replace ID
6141 packet if it is not broadcast packet already. The router must
6142 broadcast to inform other routers about changed ID.
6144 * Added backpointer to server's router into SilcServer context in
6145 silcd/server_internal.h.
6147 * Fixed silc_server_packet_broadcast to send correct broadcast
6150 * The channel key is now distributed to the local client as soon
6151 as it is received from the router (in router environment) so that
6152 no other packet may be sent for the channel until client has
6155 * silc_server_remove_channel_user now broadcasts the received
6156 Remove Channel User packet if it is not broadcast packet already.
6157 The router must broadcast to inform other routers about removed
6160 * Added users field into SilcPacketContext that is a reference count
6161 of the context. One can increase the reference count by calling
6162 silc_packet_context_dup which is now changed to just increase the
6163 reference count instead of duplicating the data. The reference
6164 count is decresed by calling silc_packet_context_free that will
6165 free the data after the reference count hits zero.
6167 For now on the packet context and everything allocated into it
6168 (including the raw packet from network) must be freed by calling
6169 the new silc_packet_context_free function. Added also new function
6170 silc_packet_context_alloc that must be used now to allocate the
6171 context. This also means that if a routine is asynchronous from
6172 silc_[client/server]_packet_parse_type the packet context must
6173 be duplicated by calling silc_packet_context_dup. Otherwise it
6174 gets free'd after silc_[client/server]_packet_parse_type returns.
6175 Also, one must remember that if packet is duplicated then its
6176 reference count must be decresed by calling the free function as
6177 many times as it was duplicated.
6179 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6180 from both client and server.
6182 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6184 * Made joining to a channel working in router environment.
6186 * Cleaned up JOIN command on server side and create function
6187 silc_server_command_join_channel internal routine to make the
6190 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6192 * Changed silc_command_pending list to SilcDList. Also, added
6193 `ident' field to SilcServerCommandPending structure to identify
6194 the reply and to call correct callback.
6196 Added silc_server_command_pending_check function to replace the
6197 corresnponding macro. The silc_command_pending list is not
6200 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6201 to set identifier to previously allocated Command Payload. It
6202 is used to set identifier for command when resending Command
6205 * Added silc_command_payload_encode_payload to encode Command
6206 Payload buffer from SilcCommandPayload structure.
6208 * Added silc_argument_payload_encode_payload to encode Argument
6209 payload buffer from SilcArgumentPayload structure.
6211 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6213 * Changed WHOIS command to support router connection on server side.
6214 The whois request is always sent to router unless the server is
6215 standalone server. After server has received the reply from the
6216 router will it send the reply to the client.
6218 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6219 broadcast received broadcast packet. The function is used only
6220 by router. The broadcast packet is always sent to the router's
6223 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6224 render given ID to printable string, for log files for example.
6226 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6228 * Made basic router to router connections working. At least they
6229 can now connect to each other but nothing really works the way
6230 they are supposed - yet.
6232 * Added new initiator token to RouterConnection configuration
6233 file in silcd/serverconfig.[ch]. It is used to tell whether we
6234 are the initiator to the remote router or whether we'll expect
6235 the other end to connect.
6237 * Moved registering of listener task to silc_server_init, hence
6238 the server starts listenning as soon as it is run, even if it
6239 does not have connections to other routers. Let's see how well
6242 * Changed default connection retry timeouts for more suitable in
6245 * Removed cipher and such arguments from silc_idlist_add_client
6246 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6247 Added new function silc_idlist_add_data to add the keys and stuff
6250 * Added SilcIDListData structure and added it to SilcClientEntry
6251 and SilcServerEntry as their first field in the structure. This
6252 way we can explicitly cast the ID entries to the SilcIDListData
6253 structure and get common data for the entries. In past, we had
6254 to first check what type of connection it is and then cast it to
6255 correct ID entry type. Now, we can directly cast the opaque
6256 pointer to the SilcIDListData (no matter what ID entry it actually
6257 is) and get the data needed.
6259 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6261 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6262 in some circumstances even if threre were timeout tasks, though not
6263 IO tasks, but tasks anyway. Now fixed.
6265 * Defined SilcServerConnection structure to hold connection specific
6266 stuff about directly connected servers and routers. The definition
6267 is currently in silcd/server_internal.h. I thought about having
6268 a bit more important role fro this struct but for now it is used
6269 only when connecting to other server (or router actually).
6271 * Added connecting retry support in server when connecting to
6272 router(s). The retry feature implement exponential backoff
6273 algorithm. Also, added SilcServerParams structure to hold default
6274 parameters for server. For now, it include these retry settings
6275 and are hard coded. After server is moded to be as Silc Server
6276 Library this structure will be more important.
6278 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6280 * Changed client librarys channel->clients table to SilcList and
6281 changed code accordingly.
6283 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6285 * Changed client's channel table to SilcList and changed code
6286 accordingly. Also changed SilcChannelClientEntry to include back-
6287 pointer to the channel so that client entry can use that structure
6288 as list as well and we have fast cross-reference to the channel.
6289 This change dramatically decreased the complexity of channel
6290 handling with client entry and vice versa (removed one extra
6291 loop when searching for channel entry from many functions).
6293 * Changed server->sim from table to SilcDList and changed code
6296 * NAMES command can now be used from user interface. It will show
6297 the user list on the channel, neatly.
6299 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6300 Code now saves realname of the user if it becomes available.
6302 * Renamed configure.in to configure.in.pre and made ./prepare
6303 script to automatically add correct version string to
6304 configure.in which it creates from configure.in.pre.
6306 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6308 * NAMES command reply now shows users mode with the nickname when
6311 * Moved silc_client_ch[u]mode[_char] functions from
6312 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6313 place sucks, they are utility functions and should be in some
6316 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6318 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6321 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6325 * Added TRQ (efficient deque and list library) into lib/trq. This is
6326 a very good list library that is currently used in the SILC. Defined
6327 SilcList API over the library because I didn't like the API very
6328 much. See lib/trq/silclist.h for the API and examples of how to
6329 use the API. Fixed various places in the code to use the new
6330 SilcList API. The SilcList is meant for lists that has a structure
6331 already defined as a list. It is not suitable to add just some
6332 context to the list (in TRQ, the context is the list actually).
6334 So, I defined SilcDList that can be used for the purpose where
6335 predefined list structure does not exit. This can be used as
6336 such list. Now some context just can be added to the SilcDList.
6337 Currently this list is not used in the SILC just yet, though there
6338 are a lot places where this can replace dynamically allocated
6339 tables and I will fix these places, later, to use SilcDList.
6340 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6341 and use TRQ internally).
6343 Also fixed some annoying warning messages that the original TRQ
6344 code generated. Also minor changes to TRQ's Makefile.in.
6346 * Added support for querying by Client ID to both WHOIS and
6347 IDENTIFY commands into server, as required by the protocol.
6349 * Removed method function pointers from SilcBuffer structure. They
6350 weren't used to anything and just increased the context size for
6351 no good reason. This change also made silc_buffer_alloc and
6352 silc_buffer_free functions inline functions.
6354 * Disabled command flooding detection support until it's fixed so
6355 that it accepts commands in but does not execute them more than once
6358 * Added silc_net_localhost(), to return local hostname, into
6359 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6360 that must be initialized before calling silc_client_init.
6362 * Added new function: silc_server_send_notify_on_channels to send
6363 notify messages to all channels client has joined. It is assured
6364 that the message is sent only once per client.
6366 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6367 lib/silcutil/silcutil.[ch] as silc_format function. The new
6368 function is generic and is used by server as well, not only by
6369 the logging routines.
6371 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6372 the provided version string was not acceptable. Added new function:
6373 silc_ske_check_version into lib/silcske/silcske.h. The function
6374 must be implemented by the application (client or server) and it
6375 does not reside in the SKE library. The function checks the version
6376 string remote end sent.
6378 * Added back pointers (to opaque context and to SilcSocketConnection)
6379 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6381 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6382 duplicate packet context structure.
6384 * Changed `notify' client operation to send same arguments as client
6385 receives from server except for ID's. ID's are mapped to correct
6386 ID entry and that is returned. Also, if channel entry is not sent
6387 by server but the notify is for channel the channel entry is sent
6388 to application (otherwise application doesn't know that it is for
6389 channel (library gets it from packet's Destination ID)).
6391 * Added silc_client_remove_from_channels into client library to
6392 remove a client from all channels it has joined to. Used when
6393 received SIGNOFF notify from server. Added also new function
6394 silc_client_replace_from_channels to replace old ID entry with
6395 new ID entry on all channels. Used when received NICK_CHANGE
6398 * Fixed ID Cache list handling in silc_idlist_get_client in
6399 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6400 to get (or query) client by ID.
6402 * Updated TODO list.
6404 * Added connection authentication status message defined by the
6405 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6406 support for these into the code in client and server side.
6408 * Added generic function silc_client_send_command to send any command
6409 with variable argument list. Application should use this function
6410 to send commands if the command functions provided by the library
6411 does not suite for the application's user interface needs.
6413 * Added new `failure' client operation. Application is notified about
6414 received failure packet if client is executing a protocol. In this
6415 case the protocol's execution has failed.
6417 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6418 is required by the protocol.
6420 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6421 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6424 * Added status flag to SilcSKE object to indicate realtime status
6425 of the SKE protocol.
6427 * Application receives now exactly same command reply arguments as
6428 the library receives from server. However, if ID is received the
6429 corresponding ID entry is returned to the application (eg. Client
6430 ID is mapped to correct SilcClientEntry entry and that is returned).
6431 Changed command_reply client operation due to this change.
6433 * Changed all ID's in commands and in command replys as ID Payloads.
6434 Change affected both client and server side codes.
6436 All ID's sent in SILC network (with execption of ID's in SILC
6437 Packet header) are sent in ID Payload to support variable length
6440 * Server now notifies nick changes and notifies all clients on
6441 the channels about the new nickname (about the new Client ID,
6444 * Implemented CMODE command to change channel modes. Supports all
6445 channel modes defined by the protocol specs except ban and invite
6446 lists. (Also, private channel key mode is supported but support for
6447 setting private channel key in client is missing, thus, this mode
6448 has no effect on client side (except that server requires that the
6449 client uses private channel key and normal channel traffic does not
6452 Also, invite mode works per se, but INVITE command does not work
6453 yet correctly, so you can set channel as invite only channel but
6454 inviting clients to the channel does not work (it is yet to be
6455 thought what's the best way to do it).
6457 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6458 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6459 Implemented CUMODE command to change user's mode on the channel.
6460 Supports all modes defined by the protocol specs.
6462 * Added NAMES command reply to return users modes on the channel.
6464 * Removed unnecessary and slow ciphers from lib/silccrypt.
6466 * Set SO_KEEPALIVE option to connection sockets by default.
6468 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6470 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6471 redefined the Notify Payload into protocol specs.
6473 * Added silc_id_payload_parse_id to get ID directly from raw
6476 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6478 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6479 accept searching by Client ID as well.
6481 * Added support for LEAVE and SIGNOFF notify types in client library.
6483 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6484 to parse ID Payload from raw data.
6486 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6488 * Added flags parameter into silc_ske_assemble_security_properties
6489 function in lib/silcske/silcske.[ch].
6491 * Changed notify client operation to fit better for notify messages
6492 sent by server. The notify payload received from server is now
6493 passed to the application (after parsing it to SilcNotifyPayload).
6494 It is application's responsibility to retrieve the arguments
6495 from the payload and show the message the way it wants. The message
6496 sent by server is implementation specific.
6498 * Changed public keys to comply with the protocol specification.
6499 Old public keys are not supported anymore and are not compatible.
6501 * Removed nickname from Channel Payload as the latest draft removed
6502 it. The client must resolve the nickname from the NAMES command
6503 reply received when it joined the channel.
6505 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6507 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6509 * Fixed some errors in protocol specification drafts.
6511 * Created lib/silccore/silcnotify.c to implement Notify Payload
6512 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6513 generic payloads described by protocol specifications. The file
6514 includes implementations for ID Payload and Argument Payload.
6516 * Changed Command Payload implementation to use the new Argument
6517 Payload. Changed command_xxxx_payload to command_payload_xxxx
6518 to comply with SILC coding conventions.
6520 * Added suppport for Argument Payload handling in Notify Payload
6521 implementation as protocol requires it. Added the new support
6522 into server and client lib as well.
6524 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6526 * Added support for multiple nicknames on same channel. [n] is
6527 added locally to the nickname if there are more than one same
6528 nicknames on the channel.
6530 * Server now sends all nicknames that matched WHOIS request.
6531 Client also shows the list received from server.
6533 * Added TOPIC command to client side. User can now set and show
6534 current topic on channel.
6536 * Added MOTD command to client and server. Also, server sends the
6537 motd when client connects to the server.
6539 * Changed version strings to comply ISO 8601.
6541 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6543 * Fixed protocol error handling in client library. It should now
6544 cope even if the SKE fails for some reason.
6546 * Made new protocol specification drafts for submitting to IETF.
6548 * Implemented TOPIC command to server in silcd/command.c.
6550 * Added two new notify types into lib/silccore/silcnotify.h:
6551 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6552 notify nickname change and topic setting/change on a channel.
6554 * API change of command_reply operation in client library. The
6555 application gets now the status type received from server as well.
6557 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6559 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6561 * Cras fixed and optimized the packet handling even further and
6562 it should work now. Minor change to the prototype of function
6563 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6565 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6567 * Added new function into lib/silcutil/silcschedule.[ch]:
6568 silc_schedule_with_fd to select() a specified fd. The function
6569 returns after timeout expires or data arrives or goes. The
6570 function is used by packet routines to wait that all data is
6571 received from network.
6573 * Fixed data reading from network in lib/silccore/silcpacket.c.
6574 The code now assures that all data is read from the fd and then
6575 continues packet processing. This was a bug fix since the code
6576 used to drop some data in some circumstances.
6578 * Added new function into lib/silcclient/client.[ch]:
6579 silc_client_start_key_exchange to start key exchange after
6580 connection has been established to server. The code internally
6581 now uses this funtion but its main purpose was to provide it
6582 for applications that perform their own connecting. After
6583 application has created a connection it merely calls this
6584 function to start the key exchange between client and server.
6585 The library takes care of everything else after that.
6587 Updated also lib/silcclient/README to explain the usage of
6590 * Do not send to application information that connection has
6591 been established. Application gets notified it by connect
6594 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6596 * Applied cras's patch to add silc_schedule_one function. The
6597 function runs scheduler once and returns.
6599 * Fixed the scheduler after cras messed it up. The timeout
6600 handling works now as it's supposed to work.
6602 * Added into lib/silccore/ silcnotify.h to include notify
6603 message types support. Changed silc_server_send_notify*
6604 functions, in server.[ch], to support those new notify types.
6605 Added the support for the notify types into client library,
6606 as well. Added new notify client operation into ops.h in
6609 * Changed silc_server_packet_send_to_channel to send normal
6610 packets instead of just channel message packets. The function
6611 is now used to send the notify packets to channels. It is not
6612 used to send channel message packets anymore, as server never
6615 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6616 va_arg()s as it seems to require it nowadays. I guess, if SILC
6617 is compiled with older va_arg() the new code should work anyway.
6619 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6621 * Splitted core library. Core library (lib/silccore) includes
6622 now only SILC protocol specific core (and common) components.
6623 Created new utility library (lib/silcutil) that includes more
6624 generic purpose stuff. The stuff for util library was taken
6625 from the old core library. This was minor and easy split.
6627 * Created SILC Client Library (lib/silcclient) that includes
6628 implementation of the SILC client without user interface. This
6629 was major move from silc/ directory. The code has been changed
6630 so that it is transparent towards the user interface. The
6631 silc/ directory includes now the same user interface as before
6632 and it uses the new client library. Read lib/silcclient/README.
6633 Basicly, the client library performs everything else related
6634 to SILC except user interface handling. Also, configuration
6635 files are considered to be part of user interface and library
6636 does not handle them.
6638 This change also changed a lot of structures, function naming etc.
6639 Most important change was that SilcClientWindow object was
6640 renamed to SilcClientConnection in the client library. Created
6641 also new file lib/silcclient/ops.h. Also added new files
6642 silc/local_command.[ch] and silc/client_ops.[ch].
6644 All these changes were made to make it easier for user interface
6645 designers to create what ever user interface for the SILC client
6648 It is also expected that the server will be moved to lib
6649 directory as well and SILC Server Library will be created;
6650 sometimes in the future.
6652 * Removed Local commands from lib/silccore/silccommand.h as
6653 they are application specific and new client library does not
6654 handle any of those anymore.
6656 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6657 old client implementation in silc/.
6659 * Added support for callback functions in SILC_LOG_* macros.
6660 Application can now set its own callbacks that will be called
6661 instead of using the default functions that will always print
6662 the debug messages to stderr (or stdout). Also, debugging can
6663 now be disabled by setting silc_debug to FALSE and re-enabled by
6664 setting it to TRUE. Note, that logging will still work even
6665 if debugging is disabled.
6667 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6668 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6669 silc_log_reset_debug_callbacks.
6671 * To enable debugging in silc client one must give now -d
6672 option on command line.
6674 * Changed silc_schedule_init to automatically allocate task queues
6675 if they are not allocated before calling it.
6677 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6679 * Added GMP 3.1 into math library.
6681 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6683 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6684 a channel in SILC network. The packet is used by servers and
6685 routers to notify other routers that user has left a channel.
6686 This little feature was missing until now. Added the feature
6687 to protocol specification as well.
6689 Added functions: silc_server_send_remove_channel_user and
6690 silc_server_remove_channel_user into server.[ch].
6692 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6693 lib/silccore/silcpacket.h. However, they are not implemented
6696 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6698 * Fixed joining to a channel and sending channel messages
6699 between server and router. The channel message sending should
6700 now work inside a cell.
6702 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6704 * Fixed the private message sending between server and router.
6705 The private message sending should now work inside a cell.
6707 * Added silc_server_replace_id into server.[ch] to replace
6708 existing ID in the SILC network.
6710 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6711 and silc_idlist_replace_server_id into idlist.[ch] in server.
6713 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6715 * Fixed the server to server connections. Server can again now
6716 connect to router. Router to router connections probably does
6719 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6721 * Added dynamic protocol registering support. Now protocols can
6722 registered and unregistered on the fly. Patch by cras.
6724 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6726 * Added lib/contrib directory to hold routines that some platforms
6727 don't have but are needed by SILC.
6729 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6730 into lin/contrib to provide getopt() and getopt_long() for
6731 those who don't have it.
6733 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6735 * Added AWAY command to client. When away message is set and
6736 client receives a private message packet the client automatically
6737 replies to the sender with the away message.
6739 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6740 bug seemed to be the cause of recent problems when compiling
6743 * Added version detection support to SKE protocol specification
6744 and added the new changes to the SKE implementation as well.
6745 There were other minor changes in the SKE protocol as well.
6747 Many changes in lib/silcske/silcske.[ch] and in
6748 lib/silcske/payload.[ch].
6750 * Added ^U functionality, clear input line. Patch from cras.
6752 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6754 * Mainly small bugfixes on core library. Fixed some debugging
6755 logging and buffer overflow in silclog.c.
6757 * Updated config.sub and config.guess on the distribution tree.
6759 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6761 * Added command lagging support in server. Client may execute
6762 commands now only once in two seconds.
6764 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6766 * Optimized packet reception. MAC computation and checking is now
6767 also more optimized. A lot previously duplicated code is now
6768 used as generic by both client and server.
6770 * Fixed key pair generation in clientutil.c
6772 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6774 * Added into lib/silccore/silcbufutil.[ch] new function;
6775 silc_buffer_realloc.
6777 * Moved generic packet sending/encryption functions to
6778 lib/silccore/silcpacket.[ch] from client and server. Some
6779 rewriting of the functions.
6781 * Moved all generic packet reception/decryption functions to
6782 lib/silccore/silcpacket.[ch] from client and server. The
6783 packet processing is now much cleaner in both client and server.
6784 These were major changes in both client and server.
6786 * Created many common functions in server to do packet sending.
6787 Previously code were duplicated a lot, this has been removed
6790 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6792 * Rewrote major parts of the ID cache system. Don't know
6793 whether it is better now or not but at least the API is more
6796 * Major rewrite on ID cache stuff on client because of the ID
6797 cache API changes. Added idlist.c to client.
6799 * Also major rewrite on ID cache stuff on server as well.
6800 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6801 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6802 in hand, instead they are all put into the ID cache system now.
6803 All server_idlist_* routines uses ID cache now instead of
6804 traversing its own lists (those lists does not exist anymore).
6805 SilcIDList though still exists. Also, SilcXXXEntry's are
6808 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6810 * Finally made the SKE implementation compliant to the protocol
6811 specification. All mp integers are now binary encoded as
6812 opposed being HEX encoded.
6814 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6817 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6818 functions: silc_[encode/decode]_pem. Also added function
6819 silc_encode_pem_file to PEM encode with newlines ('\n') for
6822 * SILC public keys are now encoded either PEM or binary. Same
6823 option is for private keys as well. By default private keys
6824 are binary encoded and public keys PEM encoded. Silly HEX
6825 encoding were removed.
6827 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6828 function to create fingerprints.
6830 * Fixed a bug in SHA1; does not change the original data anymore.
6832 * Partly implemented INFO command on client and server side.
6833 Fixed CLEAR command. Changes to SERVER command; show current
6834 server(s) when giving command without arguments. Added
6835 VERSION command to client.
6837 * Added check to server that unregistered connections cannot
6838 execute commands (unless it is specificly allowed).
6840 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6842 * Fixed screen refresh.
6844 * Fixed channel joining bug from client. On some circumstances
6845 client tried to join to a channel it had already joined.
6847 * Added public key verification process into client's protocol.c.
6848 The client now verifies the public key from user and saves
6849 it into ~./silc/serverkeys/ directory.
6851 Added into: clientutil.[ch]: silc_client_verify_server_key.
6853 * Changed SKE protocol's silc_ske_initiator_finish function
6854 to accept callback function that verifies the received public
6855 key. Removed old silc_ske_verify_public_key function.
6857 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6859 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6860 silc_pkcs_private_key[_data]_set.
6862 * Made the password and public authentication more cleaner in
6863 server's protocol.c.
6865 * Removed historic and obsolete protocol `channel_auth' from
6866 both client and server.
6868 * Removed wrong way of sending command status messages from
6869 server to client in server's command.c. The old way violated
6870 protocol specification.
6872 Changes to silccore/silccommand.[ch]: removed
6873 silc_command_encode_status_payload -> not needed anymore,
6874 changed silc_command_encode_payload_va to accept extra
6875 argument on variable argument list. The argument type must
6876 now be provided to the function. Also, added new function:
6877 silc_command_encode_reply_payload_va which is same as
6878 normal command_encode_payload_va except command status type
6879 is provided as extra argument.
6881 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6883 * Added ~./silc directory handling. The directory includes the
6884 public and private keys for the client.
6886 Added silc_client_check_silc_dir, silc_client_create_identifier
6887 and silc_client_load_keys.
6889 * Implemented SILC protocol compliant public key. Added public
6890 and private key saving to and loading from files.
6892 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6893 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6894 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6895 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6896 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6898 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6899 silc_pkcs_load_[public/private]_key.
6901 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6903 * Added silc_server_get_route (route.[ch]) to get connection
6904 data for the fastest route for given ID.
6906 * Implemented INVITE command on client and server. The command
6907 were re-defined in the SILC Protocol Specification and the
6908 implementation now complies with the specification.
6910 * Implemented PING command on client and server.
6912 * Implemented NAMES command on client and server. The server side
6913 supports currently only normal server not router server yet.
6914 Some changes to NAMES definition in SILC protocol specification.
6916 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6918 * Implemented LEAVE command on client and server.
6920 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6921 again. This change was made to the protocol as well. Server
6922 should not violate the protocol specification anymore.
6924 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6926 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6927 was tested. SOCKS4 was not but should work anyway.
