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

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

656 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
657 routines. Added silc_net_is_ip[4/6]. Affected file is
658 lib/silcutil/unix/silcunixnet.c. All routines that take
659 address as argument now supports both IPv4 and IPv6 addresses.
661 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
663 * Fixed LIST command reply sending in server. Affected file
666 * Server now sends the kicker's client ID in the KICK notify
667 to the kicked client. Affected file silcd/command.c.
669 * The client library now parses the kickers client ID and
670 UI displays it. Affected files lib/silcclient/client_notify.c
671 and irssi/src/silc/core/silc-channels.c, module-formats.c.
673 * Made all payload parsing function prototypes consistent.
674 They all take now const unsigned char * and uint32 pair as
675 the payload data instead of SilcBuffer. Changes all around
676 the source tree. Other unsigned char* -> const unsigned char*
677 changes around the tree as well.
679 * Optimized SFTP client and server packet sending not to
680 allocate new buffer for each packet but to recycle the
681 first allocated buffer. Affected files are
682 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
684 * Optimized the SFTP client to use SilcList instead of
685 SilcDList for requests, because it is faster. Affected file
686 is lib/silcsftp/sftp_client.c.
688 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
689 into lib/silccore/silcid.[ch].
691 Renamed silcpayload.[ch] into silcargument.[ch].
693 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
695 * If client entry is deleted with active key agreement
696 session, abort the session.
698 The silc_client_abort_key_agreement now calls the completion
699 callback with new SILC_KEY_AGREEMENT_ABORTED status.
701 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
704 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
706 * Don't use __restrict in older GCC's. Affected file is
707 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
709 * silc_net_localhost now attempts to reverse lookup the
710 IP/hostname. Affected file lib/silcutil/silcnet.c.
712 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
713 command. It can be used to gain founder privileges at
714 the same time when joining the channel.
716 Defined that the SILC_NOTIFY_TYPE_KICKED send the
717 kicker's client ID as well. Updated protocol specs.
719 Defined that the server must send SILC_COMMAND_IDENTIFY
720 command reply with error status to client who sent
721 private message with invalid client ID.
723 Updated the protocol specification.
725 * Added silc_server_send_command_reply to send any
726 command reply. Affected file silcd/packet_send.[ch].
728 * Added silc_id_payload_encode_data to encode ID payload
729 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
731 * The server now send IDENTIFY command reply with error
732 status if client ID in private message is invalid. Affected
733 file silcd/packet_receive.c.
735 * Save the server key file with server's IP address in
736 the filename instead of hostname. The affected file is
737 irssi/src/silc/core/client_ops.c.
739 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
741 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
744 * Added libtool support for compiling shared objects in
745 lib/silcsim. Affected file configure.in.pre and
746 lib/silcsim/Makefile.am. Original patch by cras.
748 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
750 * Pid file configuration, and server's config file fixes
751 patch by toma. Updated CREDITS file.
753 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
755 * Fixed silc_client_channel_message to not try to decrypt
756 the message twice if it resolved the destination client
757 information. This could cause of dropping one channel
758 message. Affected file lib/silcclient/client_channel.c.
760 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
762 * Added silc_client_run_one into lib/silcclient/silcapi.h and
763 lib/silcclient/client.c. This function is used when the SILC
764 Client is run under some other scheduler, or event loop or
765 main loop. On GUI applications, for example this may be
766 desired to used to run the client under the GUI application's
767 main loop. Typically the GUI application would register an
768 idle task that calls this function multiple times in a second
769 to quickly process the SILC specific data.
771 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
773 * Fixed silc_server_drop() for dropping the supplementary
774 groups as well, this could cause a security hole on some
777 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
779 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
782 * Write PID file after dropping privileges. Added -F option
783 to run server on foreground. A patch by debolaz.
784 Affected files silcd/server.c, silcd/silcd.c.
786 * Fixed MOTD to return the MOTD file server name. Affected
787 file silcd/command.c.
789 * Added INFO command reply handling to the Irssi SILC Client.
790 Affected file irssi/src/silc/core/client_ops.c.
792 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
794 * Fixed the silc_idcache_list_* routines to really support
795 the dynamic list. Fixes a crash. Affected file is
796 lib/silccore/silcidcache.c.
798 * Fixed the LIST command reply to really call LIST command's
799 pending callbacks. Affected file silcd/command_reply.c.
801 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
803 * Update conn->local_entry->nickname after giving NICK
804 command. Affected file lib/silcclient/command.c.
806 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
808 * Added the [pid] option to the silcd configuration file
810 Affected files: serverconfig.[ch] and silcd.c
812 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
814 * Save fingerprint in WHOIS command reply in server.
815 Affected file silcd/command_reply.c.
817 * Fixed NICK commands pending callback registration.
818 Affected file lib/silcclient/command.c.
820 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
822 * Use ++server->cmd_ident when sending commands in server,
823 instead of random number. Affected file silcd/command.c.
825 * Fixed GETKEY command reply to call actually GETKEY pending
826 command callbacks. Affected file silcd/command_reply.c.
828 * A bit stricter check for nicknames. Check for same nickname
829 in NICK command also. Affected file silcd/command.c.
831 * Do not call INFO command everytime client ID changes, only
832 during first connecting. Affected file lib/silcclient/client.c.
834 * Set the new nickname only after successful command reply for
835 NICK command is returned by server. Affected file
836 lib/silcclient/command.c.
838 * Remove nicknames from nicklist during server_signoff notify.
839 Should fix /NAMES bit more. The affected file is
840 irssi/src/silc/core/silc-channels.c.
842 * Added `fingerprint' field to the SilcIDListData in the
843 silcd/idlist.h to hold the fingerprint of the client's
846 Send the fingerprint of the client's public key in WHOIS
849 Affected files silcd/command.c, and silcd/idlist.[ch].
851 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
852 create fingerprint from given data.
854 * Show the fingerprint of the client's public key in WHOIS.
855 Affected files irssi/src/module-formats.[ch] and
856 irssi/src/silc/core/client_ops.c.
858 * Format the multiple same nicknames also during JOIN and
859 NICK_CHANGE notifys. Affected file is
860 lib/silcclient/client_notify.c.
862 * Do not print error on screen for invalid private message
863 payload since it can come if someone is sending private
864 messages with wrong key. Affected file
865 lib/silccore/silcprivate.c.
867 * Fixed multiple concurrent /PING crash. Affected file
868 lib/silcclient/command.c.
870 * Changed the wrong ID encoding. All IP addresses must be
871 in MSB first order in encoded format. They were encoded
872 wrong and was in LSB format. Affected files are
873 silcd/serverid.c, lib/silcutil/silcutil.c.
875 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
877 * Call the `connect' client operation through the scheduler
878 in case of error. Affected file lib/silcclient/client.c.
880 * Call the `failure' client operation even if the error
881 occurred locally during a protocol. Affected file is
882 lib/silcclient/protocol.c.
884 * Added support of sending LIST command to router from normal
885 server. This way normal server can get list of all channels
886 in the network too. Fixed the channel list sending in the
887 server too. Affected files are silcd/command.c, and
888 silcd/command_reply.[ch].
890 * Added silc_server_update_channels_by_server and
891 silc_server_remove_channels_by_server. They are used during
892 disconnection of primary router and in backup router protocol.
893 Affected file silcd/server_util.[ch], silcd/server.c and
894 silcd/server_backup.c.
896 * Fixed channel adding to global list in IDENTIFY command
897 reply in server. Affected file silcd/command_reply.c.
899 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
901 * If the incoming packet type is REKEY or REKEY_DONE process
902 that packet always synchronously. Fixes yet another MAC
903 failed error on slow (dialup) connections. Affected file
904 lib/silcclient/client.c and silcd/server.c.
906 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
908 * Call check_version SKE callback for initiator too. Affected
909 file lib/silcske/silcske.c.
911 * Implemented fix for security hole found in the SKE that was
912 fixed in the specification few days back; the initiator's
913 public key is now added to the HASH value computation.
914 Added backwards support for the old way of doing it too, for
915 old clients and old servers. Affected file is
916 lib/silcske/silcske.c.
918 * Enabled mutual authentication by default in SKE. If initiator
919 is not providing mutual authentication the responder will
920 force it. This will provide the proof of posession of the
921 private key for responder. The affected files are
922 lib/silcclient/protocol.c and silcd/protocol.c.
924 * Do not cache anymore the server's public key during SKE.
925 We do mutual authentication so the proof of posession of
926 private key is done, and if the server is authenticated in
927 conn auth protocol with public key we must have the public
928 key already. Affected file silcd/protocol.c.
930 * Added new global debug variable: silc_debug_hexdump. If
931 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
932 file lib/silcutil/silclog.[ch].
934 * Fixed compilation warning due to char * -> const char *.
935 Affected files lib/silcutil/silcnet.h, and
936 lib/silccore/silcauth.[ch].
938 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
940 * Fixed CMODE command when new channel key was created. If
941 the creation failed the old key was removed. Next time giving
942 same command would crash the server since the old key was
943 freed already. Affected file silcd/command.c.
945 * Fixed the silc_server_announce_get_channels to not crash
946 on reconnect. Affected file silcd/server.c.
948 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
950 * Added silc_log_set_debug_string function to set a regex
951 string to match for debug output. Only the function names,
952 or filenames matching the given debug string is actually
953 printed. This way it is possible to filter out those debug
954 strings that user is not interested in.
956 Fixed a bug in silc_string_regexify.
958 Affected files lib/silcutil/silclog.[ch], and
959 lib/silcutil/unix/silcunixutil.c.
961 * Changed the -d options in both server and Irssi SILC client
962 to take the debug string as argument. Affected files
963 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
965 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
967 * Added silc_hash_babbleprint to create a Bubble Babble
968 Encoded fingerprint. The encoding is developed by Antti
969 Huima (draft-huima-babble-01.txt), and it creates human
970 readable strings out of binary data. Affected file
971 lib/silccrypt/silchash.[ch].
973 * Print the babble print now in addition of fingerprint as well
974 in Irssi SILC client. Affected files are
975 irssi/src/fe-common/silc/module-formats.[ch],
976 irssi/src/fe-common/silc/core/client_ops.c.
978 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
980 * Fixed a security problem found in SKE. The initiator's
981 public key too is now added to the HASH hash value creation
982 which is signed by the responder to create the SIGN value.
983 This will prevent anyone in the middle to lie to the responder
984 about the initiator's public key. If this is done now, the
985 man in the middle will get caught. Updated the protocol
988 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
990 * Better installation directory handling. Configure module
991 paths and other paths automatically to example_silc* files
992 in doc/. A patch by toma.
994 * Fixed compiler warning from MPI library, and from SILC RNG.
997 * Added SILC_SERVER_PID_FILE to define the pid file for server.
998 It can be configured with ./configure. A patch by toma.
1000 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1002 * Find correct make to use in prepare-clean. A patch by
1003 toma. Affected file prepare-clean.
1005 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1007 * Added irssi variables use_auto_addr, auto_bind_ip,
1008 auto_bind_port and auto_public_ip.
1010 * Changed the interface for silc_client_send_key_agreement
1011 in lib/silcclient/silcapi.h
1015 irssi/src/silc/core/silc-core.c
1017 lib/silcclient/silcapi.h
1018 irssi/src/silc/core/silc-channels.c
1019 lib/silcclient/client_keyagr.c
1022 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1024 * Added silc_pkcs_public_key_compare to compare two
1025 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1027 * Check that the client who set the founder mode on the
1028 channel is the same client that is giving the founder
1029 mode to itself. It is done by comparing the saved public
1030 key (it is saved even in the authentication is passphrase).
1031 Affected file silcd/command.c.
1033 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1035 * Do not process packet for disconnected socket connection.
1036 Affected file lib/silccore/silcpacket.c.
1038 * Process the DISCONNECT packet through scheduler in the
1039 client library. Affected file lib/silcclient/client.c.
1041 * Fixed the silc_client_packet_parse to not to increase
1042 the packet sequence number if the conn->sock and the
1043 current socket connection is not same. This can happen
1044 for example during key agreement when the conn includes
1045 multiple socket connections (listeners). Affected file
1046 lib/silcclient/client.c.
1048 * The sender of the file transfer request now provides also
1049 the pointer (listener) for the key exchange protocol. If
1050 the listener cannot be created then it sends empty key
1051 agreement and lets the receiver provide the listener.
1053 Added `local_ip' and `local_port' arguments to the
1054 silc_client_file_send. If they are provided they are used,
1055 if not then it will attempt to find local IP address, if
1056 not found or bind fails then the remote client will provide
1059 Affected files are lib/silcclient/client_ftp.c and
1060 lib/silcclient/silcapi.h.
1062 * Extended the FILE SEND command to support defining the
1063 local IP and port for key exchange listener. They are
1064 optional. Affected file irssi/src/silc/core/silc-servers.c.
1066 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1068 * Defined to WHOIS command reply the sending of fingerprint
1069 of the client's public key (if the proof of posession of the
1070 corresponding private key is verified by the server).
1071 Updated to the protocol specification.
1073 * Added support of receiving the client's public key's
1074 fingerprint in command reply in client library. Affected
1075 file is lib/silcclient/command_reply.c, and
1076 lib/silcclient/idlist.[ch].
1078 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1080 * Do not send over 128 chars long nickname to the server
1081 in NICK command. Affected file lib/silcclient/command.c.
1083 * Do not send over 256 chars long channel names to the server
1084 in JOIN command. Affected file lib/silcclient/command.c.
1086 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1088 * Assure that silc_server_close_connection cannot be called
1089 twice for same socket context. Affected file is
1092 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1094 * Send error message to application if opening file for
1095 writing during file transfer fails. Affected file is
1096 lib/silcclient/client_ftp.c.
1098 Remove all file transfer sessions for a client that we're
1099 removing from ID cache.
1101 Affected file is lib/silcclient/client_ftp.c.
1103 * Fixed silc_net_addr2bin to return correct address. Affected
1104 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1106 * Fixed file transfer session removing on signoff notify.
1107 Affected file irssi/src/silc/core/silc-servers.c.
1109 * Added the SilcClientFileError to be returned in the monitor
1110 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1111 Affected file lib/silcclient/silcapi.h.
1113 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1115 * Fixed a crash in silc_client_ftp_free_sessions and
1116 silc_client_ftp_session_free_client. Affected file
1117 lib/silcclient/client_ftp.c.

1131 client library. Affected file lib/silcclient/client_prvmsg.c.
1133 * Do not actually remove the client directly from ID cache
1134 during SERVER_SIGNOFF, but invalidate it. This way we
1135 preserve the WHOWAS info for the client. Affected file
1136 silcd/server_util.c.
1138 * Fixed SERVER_SIGNOFF notify handling in the server. The
1139 server is now able to process incoming SERVER_SIGNOFF notify
1140 for a server that it doesn't even know about. It will remove
1141 the clients provided in the notify. Affected file
1142 silcd/packet_receive.c.
1144 * Check for partial packet in data queue after every packet that
1145 was found from the queue. Return and wait for more data if
1146 there is partial data in queue. Affected file is
1147 lib/silccore/silcpacket.c.
1149 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1157 * Check that newsize in silc_buffer_realloc is larger than
1158 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1160 * Added better monitor of file transfers. It now monitors
1161 key agreement protocol during the file transfer too. Added
1162 error reporting too. Affected files
1163 irssi/src/silc/core/silc-servers.c,
1164 irssi/src/fe-common/silc/module-formats.[ch].
1166 * Wrote a help file for FILE command.
1168 * Added silc_rng_global_get_byte_fast to get not-so-secure
1169 random data as fast as possible. Random data is read from
1170 /dev/urandom if available and from the SILC RNG if not
1171 available. It is used in padding generation. Affected file
1172 lib/silccrypt/silcrng.[ch].
1174 * All packets in client library are now processed synchronously.
1175 Optimized packet processing a lot. Affected file
1176 lib/silcclient/client.c.
1178 * All server connection packets are processing synchronously
1179 now in server, to optimize packet processing. Affected file
1182 * Include files are installed now only in Toolkit distribution
1183 if make install is given. Affected files: all Makefile.am's.
1185 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1187 * Assure that silc_client_notify_by_server_resolve does not
1188 resolve the client information multiple times. If it cannot
1189 be found by the first it cannot be found at all. Affected
1190 file lib/silcclient/client_notify.c.
1192 * Fixed WHOWAS command reply calling. Affected file
1193 lib/silcclient/command_reply.c.
1195 * Removed all references to silc_idlist_get_client from the
1196 Irssi SILC client since that call is internal call used by
1197 the library. The Irssi SILC client will use now client
1198 retrieval functions found in silcapi.h.
1200 * Fixed a bug in resolving nickname info before sending
1201 private message. It used freed memory. Affected file
1202 irssi/src/silc/core/silc-servers.c.
1204 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1206 * Assure my_channels statistics cannot go negative in server.
1207 Affected files silcd/server.c, silcd/server_util.c.

1223 * Added silc_net_localip to return local host's IP address.
1224 Affected file lib/silcutil/silcnet.[ch].
1226 * If key exchange or rekey protocol is active for a connection
1227 parse all packets syncronously since there might be packets
1228 in packet queue that we are not able to process without first
1229 processing packets before them. Affected file silcd/server,
1230 lib/silcclient/client.c.
1232 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1233 whether library should continue processing the packet.
1234 Affected file lib/silccore/silcpacket.h.

1280 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1281 is incomplete and is being resolved, it won't be resolved
1284 Make sure also that USERS command reply does not resolve
1285 twice information. Affected file is
1286 lib/silcclient/command_reply.c.
1288 Make sure that silc_client_get_clients_by_list does not
1289 resolve twice same information.
1291 * Check for valid client->id in the silc_server_free_client_data.
1292 Affected file silcd/server.c.
1294 * Fixed /GETKEY nick@server not to crash if the server entry
1295 is not found. Affected file lib/silcclient/command.c.
1297 * Fixed the silc_server_check_cmode_rights to check the
1298 requested modes correctly. Affected file silcd/command.c.

1302 * Better checks for non-printable chars in nick added.
1303 Affected file silcd/command.c.
1305 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1307 * Call the silc_server_udpate_servers_by_server in the
1308 primary router that comes back online in the backup resuming
1309 protocol. Otherwise it routes packets wrong. Affected file
1310 silcd/server_util.[ch], silcd/server_backup.c.
1312 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1314 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1315 lib/silcutil/silcbuffmt.[ch].
1317 * Redefined the SILC packet header to include the padding
1318 length. Affected file lib/silccore/silcpacket.[ch].
1320 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1321 length for maximum padding up to 128 bytes). Affected
1322 file lib/silccore/silcpacket.h.
1324 * Removed all backwards support for old 0.5.x MAC thingies.
1325 The SILC packet header change makes it impossible to be
1326 backwards compatible.
1328 * Send the ENDING packet with timeout in the backup resuming
1329 protocol. This is to assure that all routers has connected
1330 to the primary router. Affected file silcd/server_backup.c.
1332 * Changed the RNG to take the first IV from random data. It
1333 used to take it from zero actually. Changed the RNG also
1334 to use /dev/urandom during session. /dev/random is used
1335 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1337 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1339 * Changed the SILC packet header to have the first two bytes
1340 (the packet length) encrypted. Affected files aroung the
1341 code tree, lib/silccore/silcpacket.[ch]. Removed the
1342 SilcPacketCheckDecrypt callback. It is not needed anymore
1343 since the silc_packet_receive_process will determine now
1344 whether the packet is normal or special.
1346 * Implemented the unidirectional MAC keys. Affected files
1347 lib/silcske/silcske.c, silcd/protocol.c and
1348 lib/silcclient/protocol.c.
1350 * Implemented the packet sequence number to the MAC computation.
1351 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1352 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1353 lib/silcclient/protocol.c.
1355 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1357 * Allow backup router to announce servers. All servers
1358 announced by backup router are added to the global list
1359 automatically. Update hte server's socket to our primary
1360 router also when backup router announces a server.
1361 Affected file silcd/packet_receive.c.
1363 * Do not update the client->router in the function
1364 silc_server_udpate_clients_by_server if the client is on
1365 global list. We might fail to find any specific server
1366 for locally connected clients and local cell clients. They
1367 should still use the `from' and not `to' as client->router.
1368 This fixes backup router resuming protocol. Affected file
1369 silcd/server_util.c.
1371 * Decrease channel statistics count only if the channel
1372 deletion worked. Affected files are silcd/server.c and
1373 silcd/server_util.c.
1375 * Added silc_server_update_servers_by_server to update origin
1376 of all server entries. Used during backup router protocol.
1377 Affected files silcd/server_util.[ch], silcd/server.c. and
1378 silcd/backup_router.c.
1380 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1381 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1382 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1383 lib/silccrypt/silchmac.c.
1385 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1387 * Assure that router cannot reroute the same channel message
1388 to the sender. Affected file silcd/packet_receive.c.
1390 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1392 * Made better checks that the channel message is not sent
1393 to the router it came from. Affected file is
1394 silcd/packet_send.c. Fixed memory leak too.
1396 * Announce informations for incoming router connection, but
1397 only after checking if it is replaced by backup router.
1398 Affected file silcd/packet_receive.c.
1400 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1402 * Fixed the backup resuming protocol to work in multiple
1403 router environment. Affected file silcd/server_backup.c.
1405 * Route packet only to one router in the function
1406 silc_server_packet_send_to_channel. Affected file is
1407 silcd/packet_send.c.
1409 * Fixed silc_server_send_notify_dest to set the broadcast
1410 flag. Fixed the silc_server_send_notify_topic to actually
1411 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1412 Affected file silcd/packet_send.c.
1414 * Changed the SFTP Filesystem interface. Changed the
1415 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1416 the filesystem operation function. The SilcSFTPFilesystem
1417 is now a context that is allocated by all filesystem allocation
1418 functions and it already includes the operations structure
1419 and filesystem specific context. It is given as argument
1420 now to the silc_sftp_server_start. This made the interface
1421 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1422 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1424 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1426 * Changed the backup router adding and getting interfaces
1427 in the server. The router that will be replaced by the
1428 specified backup router is now sent as argument. Affected
1429 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1432 * Added silc_net_addr2bin_ne to return the binary form of
1433 the IP address in network byte order. Affected files
1434 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1436 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1438 * Check for existing server ID in silc_server_new_server
1439 and in silc_server_connect_to_router_final and remove the
1440 old entry if it exists. Affected file silcd/packet_receive.c,
1443 * Send the channel message always to only one router, either
1444 in upstream or downstream. Affected file is
1445 silcd/packet_send.c.
1447 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1449 * Wrote the definition of the backup resuming protocol to the
1450 protocol specification.
1452 * Removed one redundant channel key generation from normal
1453 server during joining procedure. Removed one redundant
1454 channel key sending from server to router during joining
1455 procedure. Affected file silcd/command.c.
1457 * Made minor bugfixes to the backup router resuming protocol.
1458 Affected file silcd/server_backup.c, server.c.
1460 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1462 * Added --disable-asm configuration option. Affected files
1463 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1466 * Implemented the backup resuming protocol that is used to
1467 resume the primary router position in the cell after the
1468 primary router comes back online. Affected files
1469 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1470 and silcd/server_util.[ch].
1472 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1474 * Sleep two (2) seconds after sending QUIT command to server.
1475 Affected file lib/silcclient/command.c.
1477 * Assure that if outgoing data buffer is pending do not force
1478 send any data. Affected file silcd/packet_send.c.
1480 * Assure that if outgoing data buffer is pending do not force
1481 send any data. Affected file lib/silcclient/client.c.
1483 * Implemented the backup router support when the primary router
1484 goes down. The servers and routers can now use the backup
1485 router as new primary router without loosing connectivity.
1487 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1489 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1490 in the server to indicate disabled entry. All data read
1491 from the connection will be ignored and no data is sent
1492 for entry that is disabled. Affected files are
1493 silcd/idlist.h, silcd/server.c.
1495 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1497 * Created SFTP client and server test programs in the
1498 lib/silcsftp/tests directory.
1500 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1502 * Implemented memory filesystem (virtual filesystem) for
1503 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1506 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1508 * Implemented the SFTP (SSH File Transfer Protocol) to the
1509 lib/silcsftp. It includes SFTP client and SFTP server
1512 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1514 * Moved lib/silccore/silcprotocol.[ch] to the
1515 lib/silcutil library.
1517 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1518 take variable argument list pointer as argument. Affected
1519 file lib/silcutil/silcbuffmt.[ch].
1521 * Added silc_buffer_set function that is used to set data
1522 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1523 Affected file lib/silcutil/silcbuffer.h.
1525 * Changed various routines in the core library to use the new
1526 silc_buffer_set instead of allocating new buffer only for
1529 * Added 64-bit value formatting and unformatting support to the
1530 silc_buffer_[un]format routines. Affected file is
1531 lib/silcutil/silcbuffmt.[ch].
1533 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1534 to includes/bitmove.h.
1536 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1538 * Fixed channel user mode saving in client library. Affected
1539 file lib/silcclient/command[_reply].c.
1541 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1543 * Defined the file transfer to the SILC Protocol. Added
1544 new packet type SILC_PACKET_FTP and defined File Transfer
1545 Payload. The mandatory file transfer protocol is SFTP
1546 (SSH File Transfer Protocol). Affected file in addition
1547 of the internet draft is lib/silccore/silcpacket.h.
1549 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1550 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1551 is used as part of backup router protocol when the primary
1552 router of the cell is back online and wishes to resume
1553 the position as primary router.
1555 * Redefined the MAC generation keys in the protocol. The
1556 same key is not used anymore in both direction. Both
1557 direction will now use different keys for sending and
1558 receiving. This fixes a potential security flaw. This
1559 change causes incompatibilities in the protocol.
1561 * Redefined also the MAC computation from the packet.
1562 An packet sequence number is now added to the MAC
1563 computation. This prevents possible replay attacks against
1564 the protocol. This change too causes incompatibilities
1567 Added `sequence' field to the SilcPacketContext to hold
1568 the current sequence number for the packet.
1570 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Added `created' field to the SilcIDListData in the file
1573 silcd/idlist.h to indicate the time when the entry was
1576 * Added `created' field to the SilcChannelEntry too. Affected
1577 file silcd/idlist.h.
1579 * Added `creation_time' aguments to all the announcement functions
1580 in the server. If it is provided then only the entries that
1581 was created after the provided time frame are actually
1582 announced. Affected file silcd/server.[ch].
1584 * The protocol says that the Channel ID's IP address must be
1585 based on the router's IP address. Added check for this in
1586 the silc_server_new_channel when processing incoming New Channel
1587 Payload. Affected file silcd/packet_receive.c.
1589 * Print out the correct version with --version in SILC client.
1590 Affected file irssi/src/silc/core/silc-core.c.
1592 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1594 * Fixed WHOWAS command to check for completnes of the client
1595 entry always, not just when the command is coming from client.
1596 Affected file silcd/command.c.
1598 * Added new function silc_server_packet_queue_purge to purge the
1599 outgoing data queue to the network. After the function returns
1600 it is guaranteed that the outgoing packet queue is empty.
1601 Affected file silcd/packet_send.[ch].
1603 * Purge the outgoing packet queue in the rekey protocol's final
1604 callback to assure that all rekey packets go to the network
1605 before quitting the protocol. Affected file silcd/server.c.
1607 * Added silc_client_packet_queue_parse as similar function as
1608 in server to the client library. The affected file is
1609 lib/silcclient/client.c.
1611 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1613 * Splitted silcd/server.c and created silcd/server_util.[ch]
1614 for utility functions.
1616 * Added new socket flag SILC_SF_DISABLED to indicate that the
1617 connection is open but nothing can be sent to or received from
1618 the connection. Affected file lib/silcutil/silsockconn.[ch].
1619 The checking for disabled socket is checked in the low level
1620 silc_socket_write and silc_socket_read functions.
1622 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1624 * Allow only nicknames and channel names that fits into the
1625 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1627 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1629 * When processing JOIN command reply in server check that if
1630 the channel exists in our global list we'll move it the local
1631 list. Affected file silcd/command_reply.c.
1633 * Fixed the check whether client is joined on the channel already
1634 in JOIN command. Affected file lib/silcclient/command.c.
1636 * Fixed the JOIN command reply to check whether the channel
1637 already exists. Affected file lib/silcclient/command_reply.c.
1639 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1641 * Added silc_ske_status_string to map the SKE error numbers
1642 to readable strings. The affected files are
1643 lib/silcske/silcske[_status].[ch].
1645 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1647 * Do not show the private channels on the WHOIS channel list
1648 as it is not allowed by the protocol. The affected file is
1651 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1653 * Assure that the packet length digged from the actual packet
1654 is something sensible in the silc_packet_decrypt_rest_special
1655 in lib/silccrypt/silcpacket.c.
1657 * Free and NULL the allocated pointer in silc_hmac_alloc if
1658 the HMAC allocation fails. The affected file is
1659 lib/silccrypt/silchmac.c.
1661 * Print the selected security properties to the log files in
1662 the server. Affected file silcd/protocol.c.
1664 * Add SKE's reference counter even if calling the completion
1665 callback manually. Otherwise it goes negative, although it
1666 does not cause any problems. The affected file is
1667 lib/silcske/silcske.c.
1669 * Remove the client entry with short timeout after giving the
1670 KILL command. Affected file lib/silcclient/command.c.
1672 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1673 case all found clients are already disconnected (WHOWAS would
1674 found them) in the server. Affected file silcd/command.c.
1676 * Update the last_receive (time of last data received) to be
1677 updated only when received private or channel message so that
1678 the idle time showed in WHOIS makes more sense.
1680 * Added boolean field `valid' in to the SilcClientEntry in the
1681 client library to indicate whether the entry is valid or not.
1682 This fixes the nickname change bug on channel when changing
1683 the nickname to be same than the old (like nick to Nick) the
1684 nickname formatter doesn't set the new nick anymore to Nick@host.
1685 Affected file lib/silcclient/idlist.[ch].
1687 * Now actually fixed the nickname changing on disconnection.
1688 Added new function silc_change_nick to the Irssi SILC Client.
1689 Affected file irssi/src/silc/core/client_ops.c,
1690 irssi/src/silc/core/silc-nicklist.[ch].
1692 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1694 * Check that the public key exists in the GETKEY command before
1695 trying to encode it. Affected file silcd/command.c.
1697 * Print some notifications on received public keys with GETKEY
1698 command in the Irssi SILC Client. Affected files are
1699 irssi/src/fe-common/silc/module-formats.[ch],
1700 irssi/src/silc/core/client_ops.c.
1702 * Use IDENTIFY command to resolve the server information in the
1703 GETKEY command instead of INFO command. Affected file
1704 lib/silcclient/command.c.
1706 * All command reply functions in the client library now calls
1707 the pending command reply callbacks even if an error has
1708 occurred. The server has done this a long time and now it was
1709 time to move the client library to this as well. Now all
1710 errors can be delivered back to the pending command reply
1711 callbacks if necessary. Affected files are
1712 lib/silcclient/command[_reply].[ch].
1714 * Change the nickname on disconnection back to the username
1715 because in reconnect the server will enforce it to it anyway.
1716 Affected file irssi/src/silc/core/silc-servers.c.
1718 * Fixed a config file parsing bug in the Irssi SILC client.
1719 Affected file irssi/src/silc/core/clientconfig.c.
1721 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1723 * When printing the channel mode on JOIN, verify that the
1724 channel key and channel's HMAC are valid. Affected file
1725 irssi/src/silc/core/client_ops.c.
1727 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1729 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1730 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1731 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1733 * Removed channel key rekey task deleting from the function
1734 silc_server_save_channel_key. Affected file silcd/server.c.
1735 Added explicit timeout task context instead that is used to
1736 delete the task if we are registering a new task before the
1737 new task has elapsed.
1739 * When channel key rekey occurs the client library now saves
1740 the old channel key for a short period of time (10 seconds) and
1741 is able to use it in case some is still sending channel
1742 messages encrypted with the old key after the rekey. Affected
1743 file lib/silcclient/[idlist.h|client_channel.c].
1745 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1747 * Added check to the silc_server_new_id_real to not accept
1748 new ID if it is the sender's own ID. Affected file is
1749 silcd/packet_receive.c.
1751 * Assure that we do not announce ourself or the one we've
1752 sending our announcements when we're router and are announcing
1753 servers to our primary router. Affected file silcd/server.c.
1755 * Fixed silc_server_command_identify_check_client to assemble
1756 correct WHOIS packet. It send corrupted WHOIS packet and
1757 caused problem with router to router connections. Affected
1758 file silcd/command.c.
1760 Fixed also silc_server_command_whois_check the same way
1761 as for the IDENTIFY command.
1763 * Added new SilcIDListStatus to the server in the SilcIDListData
1764 structure. The status now includes the current status of
1765 the entry (like registered, resolved etc.). Affected file
1766 silcd/idlist.[ch]. Defined a bunch of different status types
1767 as well. This replaced the old boolean registered field as well.
1769 Added resolve_cmd_ident field to the SilcClientEntry structure
1770 too so that if the entry is for example being resolved so
1771 another command may attach to the same pending command reply
1772 without requiring to resolve the same entry again. This concept
1773 should optimize the WHOIS and the IDENTIFY resolving under
1774 heavy load by taking away unnecessary resolving for entries
1775 that are being resolved already.
1777 Added support for adding multiple pending commands for one
1778 command idenfier. Affected file silcd/command[_reply].[ch].
1780 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1781 before deleting the data. Otherwise the hash table will have
1782 freed data in comparison functions. Affected file is
1783 silcd/command_reply.c.
1785 * Fixed silc_idlist_replace_client_id to add the new entry to
1786 the cache with NULL nickname. Otherwise there will be invalid
1787 memory as the nickname after the nickname is freed. Affected
1788 file silcd/packet_receive.c.
1790 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1791 saved into wrong slots because the previous number of entries
1792 was not taken into account. Affected file silcd/idlist.c.
1793 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1795 * If we are router and we receive JOIN notify to a channel that
1796 does not have any users then notified client is marked as the
1797 channel founder, as it is it. The affected file is
1798 silcd/packet_receive.c
1800 * Added to the extended hash table API's table_del_*ext functions
1801 the destructor as argument too, so that the caller can decide
1802 which destructor to use or whether to use destructor at all.
1803 Affected file lib/silcutil/silchashtable.[ch].
1805 * Fixed ID Cache purging. It actually deleted the entries from
1806 the hash table after the data was freed. The hash table ended
1807 up comparing freed memory. The affected file is
1808 lib/silccore/silcidcache.c.
1810 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1812 * Fixed Irssi SILC client's KILL command's HELP syntax.
1814 * The USERS command now resolves the detailed user information
1815 if the userinfo field is missing. Affected file is
1816 lib/silcclient/command_reply.c.
1818 * Do not print error in silc_file_read if the read file does
1819 not exist. Just silently return NULL. Affected file is
1820 lib/silcutil/silcutil.c.
1822 * Fixed the silc_log_output to not wine about NULL filename
1823 and to not create some bogus " " filename. Affected file is
1824 lib/silcutil/silclog.c.
1826 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1828 * Fixed various printing bugs on the user interface in the
1829 Irssi SILC Client. Minor changes that were forgotten from
1832 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1834 * Fixed the configure.in.pre and the compilation and distribution
1835 environment to support the new autoconf 2.52. That version is
1836 now required to compile the CVS trunk.
1838 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1840 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1841 to generally parse user@fqdn format strings. Affected file
1842 lib/silcutil/silcutil.c.
1844 * Added nickname_format and nickname_force_format fields to the
1845 SilcClientParams structure. The first one defines the format
1846 for the nicknames that the library will enforce if the receives
1847 multiple same nicknames. The second one is boolean value and
1848 can be used to force the library to always enforce the format
1849 to the nicknames regardles whether there are multiple nicknames
1850 or not. This configurable formatting was employed to flexibly
1851 support accessing multiple nicknames from the user interface.
1852 The userinterface can now set the nicknames to what ever format
1853 they prefer. Affected file lib/silcclient/silcapi.h.
1855 Added function silc_client_nickname_format to the file
1856 lib/silcclient/idlist.c. It performs the nickname formatting.
1858 Added new field `hostname´ to the SilcClientEntry context.
1859 It holds the hostname of the client. Affected file is
1860 lib/silcclient/idlist.h.
1862 * Irssi SILC Client sets the nicknames in nick@hostn format.
1863 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1864 irssi/src/silc/core/silc-core.c.
1866 The WHOIS printing now also shows both the real nickname and
1867 the formatted nickname so that user knows how to access the
1868 user if there are multiple same nicknames cached. Affected
1869 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1870 printing formatting too to take the hostname now as a separate
1871 argument. The Affected file is
1872 irssi/src/fe-common/silc/modules-formats.[ch].
1874 * Changed the silc_client_get_clients_local to accept the formatted
1875 nickname as argument. It accepts the real nickname too but the
1876 formatted nickname can be used to find the true entry from
1877 multiple entries. Affected file lib/silcclient/silcapi.h and
1878 lib/silcclient/idlist.c.
1880 * Added nickname_format_parse field to the SilcClientParams.
1881 It is a callback function provided by the application to parse
1882 the nickname out of the formatted nickname string. The library
1883 calls it to get the nickname from the formatted string. Since
1884 the application generally knows better the format of the nickname
1885 string it parses it instead of the library, even though library
1886 encodes the formatted string. If the callback function is not
1887 provided then the library will use the string as is. The
1888 affected file is lib/silcclient/silcapi.h.
1890 * All the nickname strings passed to the client library in
1891 commands are now expected to be formatted nickname strings.
1892 If the command does not support the formatted nickname string
1893 it will assume that the sent string is the actual nickname.
1894 Affected file lib/silcclient/command.c.
1896 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1898 * Added public key authentication support to OPER and SILCOPER
1899 commands in the client library. Affected file is
1900 lib/silcclient/command.c.
1902 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1904 * Changed the get_auth_methdod client operation to be asynchronous.
1905 It can be async if the application resolves the authentication
1906 method from the server during the negotiation. Added new
1907 SilcGetAuthMeth completion callback that the application will
1908 call after resolving the authentication method.
1910 Added function silc_client_request_authentication_method that
1911 the application can use to resolve the authentication method
1912 from the server. Added also SilcConnectionAuthRequest callback
1913 that the library will call after the server has replied. The
1914 application can call this function if it does not know the
1915 current authentication method.
1917 Affected files are lib/silcclient/client.c and
1918 lib/silcclient/silcapi.h.
1920 * The Irssi SILC client now automatically resolves the authentication
1921 method incase any configuration information is not present (and
1922 currently there never is). The affected file is
1923 irssi/src/silc/core/client_ops.c.
1925 * Fixed public key authentication from the client library.
1926 Affected file lib/silcclient/protocol.c. Changed also the
1927 protocol specification about the public key authentication in
1928 the connection authentication protocol. The actual data to be
1929 signed is now computed with a hash function before signing.
1931 * Fixed the public key authentication from the server as well.
1932 Affected file silcd/protocol.c.
1934 * Removed the mlock()'s from the memory allocation routines.
1935 Affected file lib/silcutil/silcmemory.c. The ./configure does
1936 not check anymore for the mlock(). Affected file is
1939 * Fixed USERS command in server to allow the execution of the
1940 command for private and secret channels if the client sending
1941 the command is on the channel. Affected file silcd/command.c.
1943 * Fixed silc_client_get_clients_local to return the clients
1944 count correctly. It could return wrong value. Affected file
1945 lib/silcclient/idlist.c.
1947 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1949 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1950 types. The assembler optimizations seemed not to like 64-bit
1951 data types. The assmebler optimizations thus are now enabled
1952 also for BSD systems as opposed to only enable them for Linux.
1954 * Do not check for threads at all on BSD systems. Affected
1955 file configure.in.pre.
1957 * Removed -n and -h options from the Irssi SILC Client since
1958 they are not used in silc.
1960 * Fixed the prime generation to assure that the first digit
1961 of the generated random number is not zero since our conversion
1962 routines does not like number strings that starts with zero
1963 digit. If zero digit is seen the random number is regenerated.
1964 This caused some corrupted RSA keys when the zero first digit
1965 was met. Affected file lib/silcmath/silcprimegen.c.
1967 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1969 * Fixed WIN32 configuration in the ./configure script.
1970 Fixed to include xti.h on environments that has it.
1971 Patches by Carsten Ilchmann and andrew.
1973 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1975 * Changed the silc_id_create_client_id to be collision
1976 resistant. It is now assured that there cannot be created
1977 two same client ID's. I suspect that some weird bugs in
1978 the server were actually caused by duplicate Client IDs.
1979 Affected file silcd/serverid.[ch]. A router receiving
1980 new ID now also assures and informs the sending server
1981 if the ID caused collision.
1983 * Changed the silc_id_create_channel_id to also assure that
1984 there are no collisions.
1986 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1988 * Statement about ignoring the Mutual Authentication flag when
1989 performing rekey with PFS was a bit misleading. It is ignored
1990 if it was set in the initial negotiation, it cannot be even
1991 set in the rekey. Fixed in the ke-auth draft. Started the
1992 new versions of the protocol drafts in the doc/.
1994 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1996 * Fixed a bug in silc_client_command_identify_save when saving
1997 new channel information. The channel name was no duplicated
1998 and caused crash on exit. Affected file is
1999 lib/silcclient/command_reply.c.
2001 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2003 * Fixed the getkey command handling in the server. Send just
2004 empty OK reply to the sender if the key could not be fetched
2005 (but everything else was ok, like the key just was not available).
2006 Changed the public key parameter to optional in the protocol
2007 specs so that empty OK reply can be sent. Affected file
2010 Added a message to Irssi SILC client to tell to user if the
2011 server did not return a public key.
2013 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2015 * Fixed a channel key regeneration bug. It registered new
2016 timeout tasks exponentially until all system resources were
2017 used. Affected file silcd/server.c.
2019 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2021 * Added the SILC Document generator to the scripts/silcdoc.
2022 It can be used to generate the Toolkit Reference Manual out
2023 of the source tree. Internally it will also use the RoboDoc
2024 generator now imported in util/robodoc.
2026 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2028 * Added couple of return's in rekey protocol if error orccurred
2029 during the protocol. The execution must be terminated.
2030 Affected file silcd/protocol.c. Also, terminate the protocol
2031 always with timeout.
2033 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2035 * The client's Client ID was created initally from the wrong
2036 nickname (it could have been in format nick@host) in the
2037 silc_server_new_client. Affected file silcd/packet_receive.c
2039 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2041 * Added some SILC_LOG_ERROR's to various error conditions
2042 if client could not be added to ID cache. Affected files
2043 silcd/packet_receive.c and silcd/server.c.
2045 * When client's sock->user_data is freed, NULL also the
2046 client->router and client->connection pointers. Added check
2047 for these pointers being NULL to various places around the
2048 code. Affected file silcd/server.c.
2050 * Added client->data.registered == TRUE checks to various
2051 places around the code to assure that unregistered client's
2052 are not handled when it is not allowed. Affected file
2055 * Added `bool registered' fields to all
2056 silc_idlist_[server|client]_get_* routines to indicate whether
2057 the fetched client needs to be registered or not. Affected
2058 file silcd/idlist.[ch].
2060 * Add your own entry as registered to the ID cache in the
2061 server. Affected file server.c.
2063 * Fixed a bug in silc_server_new_server. The SilcServer was
2064 set as the new server's context instead of SilcServerEntry.
2065 This naturally caused some weird bugs.
2067 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2069 * Do not delete the channel rekey task when adding it
2070 for in silc_server_create_channel_key.
2072 * Changed the silc_server_create_channel_key to return
2073 TRUE or FALSE to indicate the success of the channel key
2076 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2078 * Fixed MSVC++ project files and added missing files to
2079 Makefiles under win32/.
2081 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2083 * Do not add TCP_NODELAY flag if the operating system
2084 does not have it defined. Affected files are
2085 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2087 * Fixed buffer overflow from Irssi SILC Client. Affected
2088 file irssi/src/fe-common/core/themes.c.
2090 * Fixed double free in client library in the file
2091 lib/silcclient/client.c when disconnecting from server.
2093 * Applied double free patch from cras to Irssi SILC client.
2094 Affected files irssi/src/core/[modules/expandos].c
2096 * Fixed the disconnection handling to Irssi SILC Client.
2097 The application must call silc_client_close_connection
2098 in ops->connect client operation in case of failure of
2099 the connection. Affected file is
2100 irssi/src/silc/core/client_ops.c.
2102 * Do not set sock->protocol to NULL in the function
2103 silc_client_close_connection after executing the protocol's
2104 final callback since the sock might not be valid anymore.
2105 Affected file lib/silcclient/client.c.
2107 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2109 * Do not enable SILC_THREADS if the linking with libpthread
2110 did not happen. Affected file configure.in.pre.
2112 * Added notion to protocol specification that server must
2113 verify the sent authentication payload with CMODE when
2114 setting the channel founder key. Implemented it to the
2115 server. Affected file silcd/command.c.
2117 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2119 * Added _EXTRA_DIST SILC distribution variable to the
2120 distributions file. It is used to conditionally add extra
2121 files or directories to the specific distribution. Affected
2122 files ./prepare, Makefile.am.pre and distributions.
2124 Removed the `_' from the start of the distribution names.
2127 * Added README.WIN32 for instructions to compile the Toolkit
2130 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2132 * Fixed a double free in disconnection in the server. Affected
2133 file is silcd/server.c.
2135 * Fixed the lib/silcske/groups.c to work now also with GMP
2136 MP library. The string conversion did not work when using
2137 specific base and the base is indicated in the string as well.
2139 * Created win32/ directory which now includes MSVC++ specific
2140 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2141 It will appear only in the toolkit distribution
2143 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2145 * Changed the key material distribution function in case when
2146 the hash output is too short. The data is now concatenated
2147 a bit differently than it used to. Made the change to the
2148 SKE protocol specification.
2150 * Added better GMP detection to configure.in.pre. A patch
2153 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2155 * Fixed a minor bug in SKE that might cause some problem on
2156 some platforms. Affected file lib/silcske/silcske.c.
2158 * Added the cookie checking for initiator in the SKE. It checks
2159 that the responder returns the sent cookie unmodified. The
2160 affected file is lib/silcske/silcske.c. Added new SKE
2161 error type INVALID_COOKIE that can be sent during the
2162 negotiation. Fixed some memory leaks as well.
2164 * Added the "invalid cookie" error message to Irssi SILC client's
2167 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2169 * Added `task_max' field to the SilcClientParams to indicate
2170 the maximum tasks the scheduler can handle. If set to zero,
2171 default values are used. Affected file lib/silcclient/silcapi.h.
2173 * Fixed memory leaks in silc_client_close_connection. Affected
2174 file lib/silcclient/client.c.
2176 * Added silc_client_del_client_entry to client library to free
2177 all memory of given client entry. Affected file is
2178 lib/silcclient/idlist.[ch].
2180 * Added new functions silc_client_del_channel and
2181 silc_client_del_server to delete channel and server entries.
2182 Affected file lib/silcclient/[silcapi.h/idlist.c].
2184 * Removed silc_client_del_client_by_id from silcapi.h.
2186 * Fixed the INFO command to return the server's own info
2187 correctly when querying by Server ID. Affected file is
2190 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2192 * Removed the non-blocking settings in WIN32 code in the
2193 silc_sock_[read/write] and added SleepEx instead. Affected
2194 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2195 of input data is now checked with FIONREAD and ioctlsocket.
2197 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2199 * Call silc_schedule_task_del_by_context in the
2200 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2201 Affected file lib/silccore/silcprotocol.c.
2203 * Call silc_protocol_cancel for active protocols in the
2204 silc_server_close_connection if the funtion
2205 silc_server_free_sock_user_data has not been called.
2206 Affected file silcd/server.c.
2208 * Generic tasks cannot be deleted using the del_by_fd
2209 task deleting function since generic tasks does not match
2210 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2212 * Added a notion to SILCOPER help file that the SILCOPER works
2213 only on router server, not on normal server.
2215 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2217 * Added for WIN32 support for the new scheduler as well.
2218 Affected file lib/silcutil/win32/silcwin32schedule.c.
2220 * Fixed the SHA1 implementation to work on various platforms.
2222 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2224 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2225 API. It is part of the scheduler now. Everything else is
2226 as previously but some functions has changed their names.
2227 Checkout the lib/silcutil/silcschedule.h for the interface.
2228 Updated all applications to use the new interface. Affected
2229 files are lib/silcutil/silcschedule.[ch].
2231 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2233 * Found a bug in the SKE implementation. The HASH value,
2234 specified by the protocol, was not computed correctly. The
2235 public key of the responder was not added to the computation
2236 even though it is mandatory. Affected file lib/silcske/silcske.c.
2237 This unfortunately causes incompatibilities with older
2238 clients and servers.
2240 * Added WIN32 specific network init and uninit functions:
2241 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2242 the Winsock2. Affected file lib/silcutil/silcnet.h and
2243 lib/silcutil/win32/silcwin32net.c.
2245 * Set the socket always to nonblocking mode on WIN32 after
2246 reading data or writing data. Affected file is
2247 lib/silcutil/win32/silcwin32sockconn.c.
2249 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2251 * Fixed various compilation problems under WIN32. Affected
2252 files lib/silcutil/win32/silcwin32thread.c and
2253 lib/silcutil/win32/silcwin32schedule.c.
2255 * Removed all _internal.h #includes from public header
2256 files. Internal headers must never be included from
2259 Removed also the lib/silcske/payload_internal.h file.
2261 * All include files that may be needed (public and some others
2262 included by the public headers) by application developers are
2263 now copied to the ./includes directory. It does not copy any
2264 internal headers. Affected file Makefile.defines.pre and all
2265 Makefile.am's under lib/ and subdirs.
2267 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2269 * Do not change the ~/.silc directory's permissions automatically.
2270 Affected file irssi/src/silc/core/clientutil.c.
2272 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2274 * Do not cancel the protocol in silc_server_close_connection
2275 it might cause recursion. Now cancelled in the function
2276 silc_server_free_sock_user_data. Affected file silcd/server.c.
2278 * Fixed the silc_server_remove_clients_by_server to regenerate
2279 the channel keys correctly finally. Added also new function
2280 silc_server_remove_clients_channels to actually do it.
2281 Affected file silcd/server.c.
2283 * Fixed the silc_server_new_channel to not crash by giving
2284 wrong router to the new channel. Affected file is
2285 silcd/packet_receive.c.
2287 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2289 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2290 which is given as argument to the silc_client_alloc now.
2291 It can be used to configure the client and set various parameters
2292 that affect the function of the client.
2294 * The USERS command in server did not check whether the channel
2295 is private or secret. Affected file silcd/command.c.
2297 * Added new argument to the USERS command in protocol specification.
2298 The USERS command now can take the channel name as argument
2299 as well. Added support for this in client and server and
2300 updated the protocol specs.
2302 * Completed the GETKEY command in client. It can be now used
2303 to fetch also servers public key not only some clients.
2304 Affected files lib/silcclient/command[_reply].c.
2306 * Added silc_client_get_server to return server entry by the
2307 server name. Affected files lib/silcclient/silcapi.h and
2310 * Redefined the IDENTIFY command in protocol specification to be
2311 more generic. It now can be used to query information about
2312 any entity in the SILC Network, including clients, servers and
2313 channels. The query may be based either the entity's name
2314 or the ID. Added support for this in both client and server.
2316 Affected files silcd/command.c and lib/silcclient/command.c
2317 and command_reply.c.
2319 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2320 the _from_client and _from_server functions. Affected file
2323 * Added silc_client_get_channel_by_id_resolve to the file
2324 lib/silcclient/silcapi.h to resolve channel information by
2325 its ID. Added also silc_client_get_channel_by_id that
2326 does not resolve it from the server.
2328 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2330 * Added SilcServerEntry context into the client library
2331 to represent one server. The INFO command now allocates
2332 these to save the resolved server info. For now on the
2333 client library will also keep information about servers,
2334 connected and resolved with INFO.
2336 The INFO command now allocates the SilcServerEntry context
2337 and saves the server info there. The COMMAND_REPLY in
2338 the INFO now returns the parameters to application in
2339 same order as defined in the protocol specification.
2341 The entries are cached in the client->server_cache.
2343 * The INFO command is now issued after received the Client ID
2344 from the server. Affected file lib/silcclient/client.c.
2346 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2347 to the application as the mode changer might be server.
2348 It is guaranteed that NULL is not returned anymore to the
2349 application. Affected file lib/silcclient/client_notify.c.
2351 The ID Type is now also passed to the application so that
2352 it can check whether the returned entry is SilcClientEntry
2355 Added new function silc_client_get_server_by_id to return
2356 the server entry by ID. Affected files are the
2357 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2359 * Do not create the channel in the Irssi SILC Client when issuing
2360 the JOIN command but when received the sucessful JOIN command
2361 reply. Otherwise the channel might get created even though we
2362 could not join it. The Affected file is
2363 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2365 * Fixed a channel joining bug in router. The router must also
2366 check the channel modes, invite and ban lists etc. when serving
2367 the JOIN command sent by normal server. Affected file is
2368 silcd/command.c. The router now resolves the client's
2369 information from the server who sent the JOIN command if it
2370 does not know it, and processes the JOIN command only after
2373 * Changed the SilcCommandCb to take new argument; void *context2.
2374 Affected file lib/silccore/silccommand.h
2376 The second argument in the command callbacks in the server now
2377 includes the SilcServerCommandReplyContext if the command was
2378 called as pending command callback from the command reply.
2379 Otherwise it is NULL. When called as pending the status of the
2380 command reply will be checked and if it was erronous the
2381 error will be sent to the original sender of the command.
2382 This way the client always receives the error messages even
2383 though the server was actually the one who received the error
2384 when it resent the command to router, for example. Affected
2385 files silcd/command[_reply].[ch].
2387 * Fixed sending WHOWAS command's error message to client if
2388 the requested client could not be found. It was missing.
2391 * Changed the CMODE and CUMODE commands reply arguments in the
2392 protocol specification. The Channel ID is now sent in both
2393 of the commands to identify the channel. Implemented this
2394 new feature to the client and server. Affected files
2395 lib/silcclient/command_reply.c and silcd/command.c.
2397 * Made better checks for invite and ban lists in the JOIN
2398 command in server. Affected file silcd/command.c.
2400 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2402 * The server now performs the incoming host IP/DNS lookup
2403 using the silc_socket_host_lookup and thus does not block
2404 the server anymore. Affected file silcd/server.c.
2406 * Completed the multi-thread support for SILC Scheduler in
2407 the lib/silcutil/silcschedule.c.
2409 * Fixed the configure.in.pre to detect the pthread correctly
2412 * Fixed a deadlock in silc_task_queue_wakeup in the file
2413 lib/silcutil/silctask.c.
2415 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2417 * Added new function silc_schedule_wakeup that is used in
2418 multi-threaded environment to wakeup the main thread's
2419 schduler. It needs to be used when a thread adds a new task
2420 or removes a task from task queues. After waking up, the
2421 scheduler will detect the task queue changes. If threads
2422 support is not compiled in this function has no effect.
2423 Implemented the wakeup mechanism to both Unix and WIN32
2424 systems. Affected files are lib/silcutil/silcschedule.[ch],
2425 lib/silcutil/unix/silcunixschedule.c and the
2426 lib/silcutil/win32/silcwin32schedule.c.
2428 * Added new function silc_task_queue_wakeup to wakeup the
2429 scheduler by the specified task queue. Affected file
2430 lib/silcutil/silctask.[ch].
2432 * The silc_socket_host_lookup_start now wakes up the scheduler
2433 after adding the timeout task. Affected file is
2434 lib/silcutil/silcsockconn.c.
2436 * The silc_socket_host_lookup is synchronous now if the threads
2437 support is not compiled in. However, the callback is still
2438 called asyncronously through the scheduler, anyway. Affected
2439 file lib/silcutil/silcsockconn.c.
2441 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2443 * Added new function silc_socket_host_lookup to perform
2444 asynchronous IP and FQDN lookups for the socket connection.
2445 Affected files lib/silcutil/silcsockconn.[ch].
2447 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2449 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2450 that may or may not compile the mutex support in.
2452 Changed the silc_mutex_alloc interface. It allocates the
2453 mutex now to the sent pointer and returns TRUE or FALSE.
2455 Affected file lib/silcutil/silcmutex.h.
2457 * Wrote the SILC Task Queue interface to support multi-threads.
2458 Affected file lib/silcutil/silctask.[ch].
2460 * Wrote the SILC Scheduler to support multi-threads. Affected
2461 file lib/silcutil/silcschedule.c.
2463 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2465 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2466 in lib/silcutil/win32/.
2468 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2470 * Defined SILC Mutex API and SILC Thread API and implemented
2471 them for Unix. Affected files are
2472 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2473 lib/silcutil/unix/silcunixmutex.c and
2474 lib/silcutil/unix/silcunixthread.c.
2476 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2478 * Fixed the silc_server_remove_clients_by_server's channel
2479 key re-generation. The hash table handling was incorrect
2480 and would not work with many channels. Affected file is
2483 * Fixed some memory leaks around the server code.
2485 * Rewrote the silc_server_get_users_on_channel to support IPv6
2486 based Client ID's. Affected file silcd/server.c.
2488 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2489 specification. However, a separate document must be written
2490 to define the detailed signing procedure and the payload
2491 associated with the flag. Defined the flag to the
2492 lib/silccore/silcchannel.h as well.
2494 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2496 * Changed the dynamic tables to static size tables in the
2497 lib/silccrypt/silchmac.c.
2499 * Removed GCC dependencies from the code. A patch by cras.
2501 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2503 * Do not show the error "Error receiving packet bla bla"
2504 in server if it really was not an error (-2 means that reading
2505 is pending). Affected file silcd/server.c.
2507 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2509 * Fixed a possible crash in silc_server_remove_clients_by_server
2510 in silcd/server.c. Fixed there also some memory leaks.
2512 * Fixed the silc_idlist_replace_client_id. It could replace
2513 wrong key in the hash table. Affected file silcd/idlist.c.
2515 * Do not check whether there are global users on the channel
2516 if the channel->global_users is FALSE. Affected functions
2517 silc_server_remove_from_one_channel and
2518 silc_server_remove_from_channels in silcd/server.c. Also,
2519 do not check if the removed client is local as we can be
2520 sure that global client was not removed from the channel
2521 and checking for global users is not needed.
2523 * The silc_server_remove_clients_by_server now re-generates
2524 the channel keys correctly for those channels that had
2525 clients removed from them. Affected file silcd/server.c.
2527 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2529 * Found the reason of random crashes in the server. We weren't
2530 ignoring the SIGPIPE signal (which can be sent in write())
2531 and it crashed the server. Affected file silcd/silcd.c.
2533 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2535 * Assure that sock->user_data is not NULL in the function
2536 silc_server_packet_send in silcd/packet_send.c.
2538 * Disconnect the remote connection if it could not be added
2539 to any ID lists in the server. The affected file is
2542 * Check in silc_server_packet_send[_real/dest] that the
2543 socket is not disconnecting and ignore the data if it is.
2544 Affected file silcd/packet_send.c.
2546 * Define inline to __inline on native WIN32 compilation.
2547 Affected file includes/silcwin32.h.
2549 * Added some explicit type casts for inline code since MSVC
2550 require them. Affected files lib/silcutil/silcbuffer.h,
2551 lib/trq/silcdlist.h and lib/trq/silclist.h.
2553 * Print warning in log files from now on if the packet
2554 decryption fails. Affected file silcd/server.c.
2556 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2558 * Changed the `say' client operation's interface to accept
2559 new `type' argument to indicate the type of the message sent
2560 by the library. The application may filter the library's
2561 messages according the type. The affected file is the
2562 lib/silcclient/silcapi.h.
2564 * Added two new functions to lib/silcclient/silcapi.h:
2565 silc_client_del_client and silc_client_del_client_by_id.
2566 Affected file lib/silcclient/idlist.c.
2568 * Moved the clientincludes.h from includes/ to silc/ and
2569 serverincludes.h from includes/ to silcd/.
2571 * The modes for the CMODE and CUMODE are now passed as
2572 uint32 for application with COMMAND_REPLY. The affected
2573 file is lib/silcclient/command_reply.c.
2575 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2577 * /WHOIS without arguments shows client's own information.
2578 Affected file lib/silcclient/command.c.
2580 * Changed PING to not accept any arguments. The specs
2581 says that client can ping only the connected server so
2582 requiring an argument is not needed. Affected file is
2583 lib/silcclient/command.c.
2585 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2587 * Fixed a fatal bug in private message sending and reception
2588 encryption and decryption when using private message keys.
2589 The implementation was incorrect and did not follow the
2590 specification. It causd that some of the message were
2591 lost since it did not use the sending and receiving keys
2592 as the protocol suggests. This has been fixed and will cause
2593 incompatibilities with older clients when sending private
2594 message encrypted with private message keys. Affected files
2595 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2596 and various other in Irssi SILC Client.
2598 Added `responder' boolean argument to the functions
2599 silc_client_add_private_message_key[_ske] to indicate when
2600 the key is added as responder or initiator of the key
2603 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2605 * Removed the silc_ske_check_version function and created
2606 a SilcSKECheckVersion callback. Added also a function
2607 silc_ske_set_callbacks that is now used to set all SKE
2608 callbacks. The callback functions are not given to
2609 the SKE functions anymore, but this function is used to
2612 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2614 * Added `silc_version' argument to the silc_client_alloc
2615 to define the version of the application for the library.
2616 The library will use the version string to compare it
2617 against the remote host's (usually a server) version
2618 string. Affected file lib/silcclient/silcapi.h
2620 * Added the KE protocol context to Key Agreement context
2621 in client library so that we can abort the SKE if it
2622 is in process when we get timeout. Affected file is
2623 lib/silcclient/client_keyagr.c.
2625 * Do not resolve the client ID forever if it returns in the
2626 first time that such client does not exist. This was done
2627 for example with private message. Affected file is
2628 lib/silcclient/client_prvmsg.c.
2630 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2632 * Do not add regex.h for WIN32. The affected file
2633 includes/silcincludes.h.
2635 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2636 not work yet 100%. It generates the DLL's automatically
2637 when compiling with --with-win32 under cygwin.
2639 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2641 * lib/contrib/regex.c is not compiled on WIN32.
2643 * Added silc_net_get_socket_opt function to the
2644 lib/silcutil/silcnet.h.
2646 * Added includes/silcwin32.h for WIN32 specific includes
2649 * Do not use ptime structure or any of the posix process
2650 functions on WIN32 in lib/silccrypt/silrng.c.
2652 * Added silc_gettimeofday to provide generic function
2653 for struct timeval on all platforms. Added the function
2654 to lib/silcutil/silcutil.h.
2656 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2658 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2659 library as they clearly belong there. As a plus side we
2660 can make the actual socket connection routines platform
2663 Added also new generic function silc_socket_read and
2664 silc_socket_write (that used to be silc_packet_[read/write].
2665 The implementation of these are platform specific.
2667 * Added WIN32 specific routines of silc_socket_[read/write]
2668 to lib/silcutil/win32/silcwin32sockconn.c.
2670 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2672 * Added preliminary support for native WIN32 compilation under
2673 cygwin (using the -mno-cygwin option for GCC) to the
2674 ./configure.in.pre. The --with-win32 now prepares the
2675 compilation for native WIN32.
2677 * Rewrote the SILC Scheduler interface in the file
2678 lib/silcutil/silcschedule.h. The scheduler is now context
2679 based and does not have anymore any global static scheduler.
2680 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2681 and created lib/silcutil/win32 directory for WIN32 based
2684 * Added Unix specific network routines to the
2685 lib/silcutil/unix/silcunixnet.c and the old
2686 lib/silcutil/silcnet.c includes now only generic routines.
2688 Added WIN32 specific network routines to the
2689 lib/silcutil/win32/silcwin32net.c.
2691 * Added Unix specific utility functions from the
2692 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2694 * Added WIN32 SILC Scheduler to the file
2695 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2698 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2700 * Do not handle JOIN notify in the server if the target client
2701 is not registered (idata->registered == FALSE). The affected
2702 file is silcd/packet_receive.c.
2704 * Update the nickrec->founder in event_cumode in the Irssi SILC
2705 client. Affected file irssi/src/silc/core/silc-channels.c.
2707 * Fixed the CUMODE_CHANGE notify handling in the server when
2708 server and router are announcing their clients on channels.
2709 Now the mode changes are saved and notified correctly. The
2710 affected file is /silcd/packet_receive.c.
2712 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2713 They really did not replace the cache entry in the ID Cache.
2714 Now they do that. Affected file silcd/idlist.c.
2716 * Fixed the KICK notify handling in the Irssi SILC client to
2717 update the channel records so that the kicked client does not
2718 appear to be on the channel. The affected file is
2719 irssi/src/silc/core/silc-channels.c.
2721 * Always update the conn->current_channel when executing command
2722 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2724 * Fixed the KILL notify handling in Irssi SILC client to remove
2725 the killed client on all channels.
2727 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2729 * Fixed the silc_parse_command_line to remove extra spaces
2730 from the start and end of the arguments. Affected file is
2731 lib/silcutil/silcutil.c.
2733 * Cancel and free any active protocol in the function
2734 silc_server_close_connection. Affected file silcd/server.c.
2736 * Cancel and free any active protocol in the function
2737 silc_client_close_connction. Affected file is
2738 lib/silcclient/client.c.
2740 * Do not execute the KILL command for clients that are in
2741 history (ie. they are not in the network). Affected file is
2744 * Fixed KILL notify handling, client does not crash anymore.
2745 Affected file irssi/src/silc/core/silc-channels.c.
2747 * Reduced the default packet buffer size from 2048 to 1024 in
2748 lib/silccore/silcpacket.c.
2750 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2751 counter to the SKE context that is incresed when the SKE library
2752 performs async operation outside the library. If the outside
2753 process frees the SKE context and FREED status will be set
2754 and the library will detect after the sync operation that the
2755 libary is freed. The affected files are
2756 lib/silcske/silcske[_status].[ch].
2758 * Resolve the client entry information in the function
2759 silc_client_channel_message to assure that NULL pointer is not
2760 passed as client entry to the application. */
2762 * Fixed the task timeout calculation to assure that there is
2763 never negative timeouts. The affected file is
2764 lib/silcutil/silcschedule.c.
2766 * Fixed the channel user mode notification sending in server.
2767 It was sent point-to-point to the router (or to server by router)
2768 but it needs to be destined to a channel. The routines now
2769 supports sending the channel user mode notifys to the channels
2770 when announcing clients and channels. Affected files are
2771 silcd/server.c and silcd/packet_receive.c.
2773 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2774 It did not actually replace the old channel entry in the cache.
2775 Affected file lib/silcclient/client_notify.c.
2777 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2779 * Fixed a possible crash in silc_packet_send_prepare. It now
2780 assures always that there is enough space in the buffer and
2781 at the tail area of the buffer (for MAC).
2783 Fixed the inbound buffer reallocation in silc_packet_read.
2784 It was old code and did not handle the reallocation correctly.
2787 The affected file is lib/silccore/silcpacket.c.
2789 * Fixed buffer overflow in silc_parse_nickname in the file
2790 lib/silcutil/silcutil.c.
2792 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2794 * make install generates new server keys only if there is not
2797 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2799 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2800 Added check that if the NOREPLY is set then we will not send
2801 the away message. This avoids infinite loop of away messages
2802 if both clients are away. The affected file is
2803 lib/silcclient/client_prvmsg.c.
2805 * Fixed client crash if /NICK was given without arguments.
2806 Affected file lib/silcclient/command.c.
2808 * Server does not send the invite list in INVITE command back
2809 to the client if the list was not altered. Added this notion
2810 to the protocol spec as well. Affected file silcd/command.c.
2812 Fixed possible crash in INVITE command by checking the
2813 value of silc_server_get_client_route command.
2815 * Fixed the INVITE notify type handling. The arguments are now
2816 taken in correct order and client does not crash. The affected
2817 file is irssi/src/silc/core/silc-channels.c.
2819 Removed the "Inviting xxx to channel" message from the
2820 client library away and let the application handle it.
2821 Affected file lib/silcclient/command.c. Added that message
2822 to Irssi SILC client's message formats.
2824 * Fixed CMODE command crash in client. It now checks the
2825 amount of arguments correctly and does not crash. The affected
2826 file is lib/silcclient/command.c.
2828 * Do not create new channel automatically in silc_channels_join
2829 but check whether the channel by that name already exists.
2830 Affected file irssi/silc/core/silc-channels.c.
2832 * Do not send the SERVER_SIGNOFF to router if the disconnected
2833 entity was the router. Affected file silcd/server.c.
2835 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2836 SILC client as it was missing from there.
2838 Added the handling of the KICK notify to the Irssi SILC client
2839 as it was missing. Added "you have been kicked" message to
2840 Irssi SILC client's message modules formats.
2842 Added the handing of the KILL notify to the Irssi SILC client
2843 as it was missing. Added the kill message module formats
2846 The affected file is irssi/src/silc/core/silc-channels.c.
2848 * The router did not save the channel mode the server announced.
2849 Affected file silcd/packet_receive.c.
2851 * Fixed a possible crash in INFO command in server. If the
2852 server did not provide the server info it crashed. Affected
2853 file silcd/command.c.
2855 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2857 * Fixed the GETKEY command in the server to check also the
2858 global list. Otherwise the GETKEY would not work correctly
2859 in normal SILC server. Affected file silcd/command.c.
2861 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2863 * Fixed GETKEY crash, it crashed if the command did not succseed.
2865 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2867 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2868 is now real and not just an macro interface to GMP.
2870 Removed the entire GMP from the source tree and imported new
2871 NSS MPI library instead. Reason for removing GMP is that it is
2872 extremely large and compiles extremely slow. The NSS MPI
2873 is only a few files and compiles in less than 10 seconds.
2874 The speed is also about the same as GMP. The MPI is imported
2875 to lib/silcmath/mpi.
2877 If the system has GMP installed we will still use the GMP.
2878 If it is not then the NSS MPI will be compiled.
2880 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2882 * Merged a long nickname (127 characters long) crash bugfix from
2883 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2885 * Merged a freed memory reference bugfix from Irssi CVS tree.
2886 Affected file irssi/src/core/commands.c.
2888 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2890 * Added the server's public key sving and verification to the
2891 server when performing the SKE. This was missing and the
2892 remote server's (or router's) public key was accepted without
2893 checking whether we have it previously or trust it at all.
2894 Affected file silcd/protocol.c.
2896 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2898 * Check in the silc_server_timeout_remote if protocol is active
2899 and make sure that the protocol's final callback is called so
2900 that all memory if freed. Affected file silcd/server.c.
2902 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2904 * silc_server_whois_send_reply crashed the server if the nickname
2905 was 127 characters long. Affected file silcd/command.c.
2907 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2909 * Added sanity check to the silc_server_new_client. If the hostname
2910 is provided inside username then check that the provided hostname
2911 really is the same as the resolved one. If the hostname was not
2912 resolved then check it from the public key. Affected file is
2913 silcd/packet_receive.c.
2915 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2916 if the server disconnected us and the connection is not valid
2917 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2919 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2920 the library to the lib/silcutil/silcutil.[ch].
2922 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2924 * Close log file after open. Affected file
2925 lib/silcutil/silclog.c.
2927 * Check whether sock == NULL in silc_client_send_packet and return
2928 if it is. Affected file lib/silcclient/silcclient.c.
2930 * Check rec->entry == NULL in the Irssi SILC Client before
2931 sending the channel message. Affecte file is
2932 irssi/src/silc/core/silc-servers.c.
2934 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2936 * Merged a splitted window bugfix from Irssi CVS tree. The
2937 affected file is irssi/src/fe-text/textbuffer-view.c.
2939 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2940 It did not print nickname.
2942 * Improved the distributions system a bit.
2944 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2946 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2947 irssi/src/fe-text/gui-window.c.
2949 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2950 to in-active server. The affected file is
2951 irssi/src/silc/core/client_ops.c.
2953 * Resolve the client in USERS command reply if the entry does
2954 not have username resolved. The affected file is
2955 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2956 command to WHOIS command to really resolve stuff. The USERS
2957 is not used any more in any critical section so WHOIS can
2958 be used even though it might be slower than IDENTIFY.
2960 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2963 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2965 * Changed the protocol API a bit more consistent in the
2966 lib/silccore/silcprotocol.[ch].
2968 * Changed the following headers to ROBODoc format:
2970 lib/silccore/silcpayload.h
2971 lib/silccore/silcprotocol.h
2972 lib/silccore/silcsockconn.h
2974 All core library headers are now formatted.
2976 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2978 * Fixed a bug in Irssi SILC client; do not show that you are
2979 server/router operator if you really are not. Affected file is
2980 irssi/src/silc/core/client_ops.c.
2982 * Renamed silc_command_free_payload to silc_command_payload_free.
2983 Affected file lib/silccore/silccommand.h
2985 * Added silcmath.h to include the prototoypes of various routines
2986 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2989 * Changed the following headers to ROBODoc format:
2991 lib/silccore/silcchannel.h
2992 lib/silccore/silccommand.h
2993 lib/silccore/silcid.h
2994 lib/silccore/silcidcache.h
2995 lib/silccore/silcmode.h
2996 lib/silccore/silcnotify.h
2997 lib/silccore/silcpacket.h
2998 lib/silcmath/silcmath.h
3000 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3002 * Added checking to the server code not to start the server if
3003 ciphers and stuff are not configured properly. Affected files
3004 silcd/serverconfig.[h] and silcd/server.c.
3006 * Changed the layout of the header files of the public interfaces
3007 in the SILC libraries. The new layout supports ROBODoc
3008 documentation tool (and some others) so that it is easy to create
3009 a library reference manual. All the other headers and source
3010 code must still follow the CodingStyle document. Also source
3011 code must not include these ROBODoc stuffs, only the headers.
3012 Furthermore, all public interface headers must now be named
3013 by using `silc' prefix, example: silcapi.h, silccipher.h.
3014 Some files were renamed due to this. All the other headers
3015 must not be used as public interfaces. I will update the
3016 CodingStyle document later. Changed following headers, so far:
3018 lib/silcclient/silcapi.h
3019 lib/silccore/silcauth.h
3020 lib/silccore/silcprivate.h
3021 lib/silccrypt/silcdh.h
3023 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3027 * Removed silc_client_packet_send_flush from the client library
3028 as it is not needed. Affected file lib/silcclient/client.[ch].
3030 * Added printing of message of unresolved authentication method
3031 to the Irssi SILC client. Added it to the module formats.
3032 Removed the same message from the client library.
3034 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3036 * Added new distribution feature, DISTLABEL. Every distribution
3037 can define own preprocessor label that can be used in the
3038 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3039 file distributions, acconfig.h.pre and prepare.
3041 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3043 * Added Makefile.defines_int to include the actual definitions
3044 for Makefile.defines.in. Tested the new distribution system,
3045 created distributions and tested installation.
3047 * Added AWAY message printing to the Irssi SILC client. Added
3048 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3050 * Added SCONNECT command to call the SILC's CONNECT command.
3051 Cannot use CONNECT directly since Irssi uses that internally.
3052 Affected file irssi/src/silc/core/silc-servers.c.
3054 Added ACTION local command. It is same as ME command but takes
3055 the channel as mandatory argument.
3057 Rewrote some of the Irssi's help files to suite for SILC
3060 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3062 * Added Makefile.defines[.in] that should for now on be included
3063 in all Makefile.am file in the source tree. That file includes
3064 all common compilation definitions for SILC source tree.
3066 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3068 * Minor changes to the ./prepare script to change the package
3069 name according the distribution name to the configure.in.
3071 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3073 * Created new distribution system. Added file `distributions'
3074 that defines all the distributions that can be created out of
3075 the SILC source tree. The ./prepare script now reads that
3076 file to determine how to prepare the distributions. The
3077 first argument to the ./prepare is the name of the distribution
3078 and second is the version of the distribution. If given
3079 without arguments it creates the default (toolkit) distribution
3080 with the default version (defined in ./prepare).
3082 All Makefile.am files that are subject to the distributions
3083 are now named as Makefile.am.pre. These are ./Makefile.am
3084 and lib/Makefile.am. Others may be changed later.
3086 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3088 * Added invite list, ban list, some key management and connection
3089 error message printing to module formats in the Irssi SILC client.
3091 * Added new silc_client_set_away_message to set the away message
3092 that is back to the person who sent private message. The
3093 affected file lib/silcclient/silcapi.h and the
3094 lib/silcclient/client_prvmsg.c.
3096 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3098 * Fixed the private message sending in the Irssi SILC client,
3099 added local command KEY to the Irssi SILC client.
3101 Added key management and key agreement message formats to the
3102 irssi/src/fe-common/silc/module-formats.[ch].
3104 Added USERS (alias WHO) printing, server/router operator
3105 indication and LIST command printing to the module formats.
3107 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3109 * Fixed channel joining notify handling, cumode notify handling
3110 from Irssi SILC client.
3112 * Added SILC specific module-formats to the Irssi SILC client so
3113 that SILC specific message hilighting, colors etc is possible.
3114 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3116 Added channel mode, channel user mode, actions, notices,
3117 whois and whowas printing to the the module-formats.c.
3119 * Fixed a bug in channel deletion in the server. The channel
3120 is not left to the cache even if the channel founder auth mode
3121 is set when there are no users anymore on the channel. Affected
3122 file silcd/server.c.
3124 * The silc_net_localhost now resolves the entire hostname including
3125 the domain name. Affected file lib/silcutil/silcnet.c.
3127 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3129 * Changed the ask_passphrase client operation to be ascynchronous.
3130 It has now a completion callback and a context that the
3131 application must call after it has got the passphrase from
3132 the user. Affected files lib/silcclient/silcapi.h,
3133 lib/silcclient/protocol.c, lib/silcclient/command.c and
3136 Added SilcAskPassphrase callback that the application calls
3137 to deliver the passphrase to the library.
3139 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3140 The public key verification and especially a certificate
3141 verification is asynchronous procedure.
3143 Added new SILC_SKE_STATUS_PENDING status to indicate the
3144 request is pending and a callback will be called to finalize
3147 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3148 indicate that remote end did not send its public key (or
3149 certificate), even though we require it. Added check for this
3150 condition in the SKE. This was a security bug, now fixed.
3152 Defined new SilcSKEVerifyCbCompletion callback that is called
3153 when the verification process is completed.
3155 The affected files lib/silcske/silcske_status.h and
3156 lib/silcske/silcske.[ch].
3158 * Changed the verify_public_key client operation to be async
3159 as well. Defined SilcVerifyPublicKey callback that is used to
3160 indicate the success of the public key verification process.
3162 Changed the server and client to use the new async client
3165 * Changed the Irssi SILC client's internal scheduler to be called
3166 twice as many times as it used to be. As a result the client
3167 should be a bit faster now. Affected file is
3168 irssi/src/silc/core/silc-core.c.
3170 * Added support to Irssi SILC client of asynchronous public key
3171 verification and passphrase inquiry. Affected file is
3172 irssi/src/silc/core/silc-core.c.
3174 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3176 * Do not say "You have left channel %s" in client library.
3177 Moved it to the application. Affected files are
3178 lib/silcclient/command.c and silc/client_ops.c.
3180 * Fixed silc_client_get_clients. Command context was not
3181 duplicated and was freed memory in the callback. Affected
3182 file lib/silcclient/idlist.c.
3184 * Do not say "you are now talking..." on JOIN command in the
3185 client library. The appliation must handle it.
3187 * Do not say ".. changed topic to" in command reply in the
3188 client libary. The application must handle it.
3190 * Fixed TOPIC command sending in the client library.
3192 * Fixed a memory leak in silc_client_command_free in the file
3193 lib/silcclient/command.c.
3195 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3197 * Imported a modified version of Irssi client to the source tree.
3198 The Irssi will be used to create a new client called
3199 Irssi SILC. Imported to irssi/.
3201 Added silc_core_init_finish function to the Irssi. Affected
3202 file irssi/configure.in.
3204 A lot changes in the Makefile.ams around the irssi tree.
3206 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3208 * Do not rehash if the new size is same as the old size of the
3209 hash table, in the silc_hash_table_rehash*. The affected file
3210 lib/silcutil/silchashtable.c.
3212 * Replaced hash_table_del_by_context calls from the server
3213 (when channel->user_list and client->channels) to the
3214 hash_table_del as it is sufficient and faster.
3216 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3218 * Added silc_hash_table_list, silc_hash_table_get and the
3219 SilcHashTableList structure to provide an alternative way to
3220 traverse the hash table. The affected files are
3221 lib/silcutil/silchashtable.[ch].
3223 * Changed the server's idlist routines to use the hash table
3224 routines to optimize the code.
3226 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3228 * Replaced the client entry's `channel' list and channel entry's
3229 `user_list' list to hash tables for optimized lookup. Changed
3230 the code to use the hash table interface around the code.
3231 Affected file lib/silcd/idlist.[ch].
3233 * Added `auto_rehash' boolean argument to the function
3234 silc_hash_table_alloc to indicate whether the hash table should
3235 auto-rehash when it thinks is appropriate time. It will
3236 increase the hash table size if the there is twice as much
3237 entries in the table than the size of the table, and will
3238 decrease the size if there are twice as less entries than
3239 the size of the table.
3241 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3243 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3245 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3247 * silc_idcache_purge_by_context deletes the entry now by context
3248 as it is supposed to do. Affected file lib/silccore/idcache.c.
3250 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3251 client is not anymore valid (WHOWAS givens the info) and not
3252 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3254 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3256 * Removed the `data' and `data_len' arguments from the ID Cache
3257 interfaces and added `name' argument. ID Cache does not handle
3258 anymore the binary data only a names associated with given ID.
3260 * When hashing a Client ID with silc_hash_id the entire ID is
3261 not hashed anymore, instead only the hash of the Client ID is
3262 hashed. This way we can access the Client ID from the cache
3263 with Client ID but with the hash of the ID (which is a hash of
3264 the nickname) as well without any difference in performance.
3266 Added also silc_idcache_find_by_id_one_ext to do one on one
3267 searching when we have the actual ID. Added also function
3268 silc_hash_client_id_compare. The affected files are
3269 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3271 * When hashing the name associated with a ID it is always done
3272 in lowercase. This way we can access the cache without worrying
3273 about case-sensitivity, even though, for example nicknames are
3276 * Fixed a bug in server with channel message sending. It put
3277 wrong ID type as destination ID. The affected file
3278 silcd/packet_send.c.
3280 * silc_idcache_del_by_context now deletes from all hash tables
3281 by context. Affected file lib/silccore/idcache.c.
3283 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3285 * Changed the client library to use the new ID Cache interface.
3286 Changes around the source tree.
3288 * Added silc_hash_table_rehash_ext to rehash with specific
3289 hash function. Affected file lib/silcutil/silchashtable.[ch].
3291 * Added silc_hash_string_compare to compare two strings in the
3292 hash table. Affected file lib/silcutil/silcutil.[ch].
3294 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3296 * Added new function silc_idcache_del_by_context into the
3297 lib/silccore/idcache.[ch].
3299 * Changed the server's ID list routines to use the new ID Cache
3300 interface. Changes around the source tree.
3302 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3304 * Added silc_hash_table_del[_by_context]_ext functions in to the
3305 lib/silcutil/silchashtable.[ch].
3307 Removed silc_hash_table_find_all* routines and added new
3308 silc_hash_table_find_foreach to replace them.
3310 Added silc_hash_table_replace_ext function as extended
3311 replacing function. Separated the simple hash table interface
3312 from the extended hash table interface in the file
3313 lib/silcutil/silchashtable.h.
3315 * Fixed minor bugs and changed it to use some of the new
3316 hash table functions in lib/silccore/idcache.c
3318 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3320 * Added new function silc_hash_table_find_all to return all keys
3321 in the hash table by the specified key. As the hash table is
3322 collision resistant it also makes it possible to have several
3323 duplicate keys in the hash table. This function may be used to
3324 find all of the keys from the hash.
3326 Added user_context arguments to the SilcHashFunction,
3327 SilcHashCompare and SilcHashDestructor to deliver user specified
3330 Added new fuctions silc_hash_table_find[_all]_ext to do
3331 extended lookup with specified hash and compare functions and
3332 specified user contexts.
3334 Added new function silc_hash_table_add_ext to add the key
3335 with specified hash function and user context.
3337 Added new function silc_hash_table_foreach to traverse all
3338 entrys in the hash table. Added SilcHashForeach callback
3341 Added new function silc_hash_table_del_by_context to delete
3342 the entry only if the context associated with the key matches.
3344 Affected files are lib/silcutil/silchashtable.[ch].
3346 * Removed silc_hash_[server/client/channel]_id and added just
3347 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3348 silc_hash_id_compare to compare two ID's using as the hash table
3349 comparison function. Added also silc_hash_data to hash
3350 binary data and silc_hash_data_compare to compare it.
3352 * Removed silc_idlist_find_client_by_hash as it is not needed
3353 anymore. Affected file silcd/idlist.[ch].
3355 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3356 to use internally the SilcHashTable. The new ID Cache is a lot
3357 faster than the old one. Some of the ID Cache interface was also
3358 rewritten and obsolete and stupid functions were removed.
3360 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Added entry_count field to the SilcHashTable to keep the number
3363 of the entries in the table. Implemented the function
3364 silc_hash_table_rehash. Added new function
3365 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3367 Fixed a minor bug in silc_hash_table_free.
3369 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3370 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3371 into the lib/silcutil/silcutil.[ch].
3373 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3375 * Implemented a collision resistant hash table into the
3376 lib/silcutil/silchashtable[ch]. See the header and the source
3377 for the SilcHashTable API.
3379 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3381 * Merged dotconf version 1.0.2 into lib/dotconf.
3383 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3385 * Do not compile anything in lib/silcsim/* if the SIM support
3386 is not enabled. The tree should now compile without problems
3389 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3391 * Compiled the SILC under cygwin. Compiled and tested briefly
3392 without problems. More tests needed. The SIMs didn't compile
3395 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3397 * Fixed possible crash in silc_get_username in the
3398 lib/silcutil/silcutil.c.
3400 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3402 * Fixed a va_arg in silc/client_ops.c.
3404 * Oops, RC5 routines were named AES and caused some problems
3405 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3407 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3409 * Added new SilcIDIP structure into the lib/silccore/id.h and
3410 replaced the old `ip' fields from all SILC ID's to that type.
3411 This is a step towards IPv6 support.
3413 The silc_id_get_len takes now the ID as an extra argument.
3414 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3415 both IPv4 and IPv6 based ID's.
3417 The affected files are lib/silccore/id.[ch] and other files
3418 around the tree using these routines.
3420 * Removed the ID length arguments in server from various
3421 silc_server_send_notify_* routines -> they are not needed
3424 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3426 * Fixed memory leak in silc_encode_pem_file in the file
3427 lib/silcutil/silcutil.c.
3429 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3431 * Check minor version as well in the SKE. Affected files are
3432 silcd/protocol.c and lib/silcclient/protocol.c.
3434 * Added --identifier option to the server so that an identifier
3435 can be when creating the public key for the server. Affected
3436 file is silcd/silcd.c.
3438 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3439 lib/silccrypt/silcpkcs.c.
3441 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3443 * Register default ciphers and stuff when using -C option with
3444 the server. Affected file sildc/silcd.c.
3446 * Put back the servers public key filename format, it is better
3447 than the new one. For now, the client keys are saved with the
3448 new filename format. The affected file silc/client_ops.c.
3450 * Implemented the Cipher API for the rest of the ciphers that
3451 did not implement it or implemented it the wrong way.
3453 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3455 * Register default ciphers and stuff when using the -S option
3456 in the client. Affected file silc/silc.c. Same also when
3457 creating new key pair with -C option.
3459 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3461 * Fixed the silc_verify_public_key client operation function to
3462 save the public keys differently. The fingerprint is now
3463 used as filename and not the hostname. This way also the
3464 client keys are saved uniquely and not with hostnames. The
3465 affected file is silc/client_ops.c.
3467 * Trimmed the silc_hash_fingerprint function to remove extra
3468 whitespaces from the end of the fingerprint. The affected
3469 file is lib/silccrypt/silchash.c.
3473 * Added silc_cipher_register_default function to register all
3474 default ciphers. It can be used when configuration files
3475 does not exist and the application does not want any specific
3476 ciphers in any specific order.
3478 The SilcDList is now used as silc_cipher_list dynamically
3479 allocated cipher list. Removed the static list all together
3480 and now all ciphers must be allocated to the dynamic list.
3481 The silc_cipher_alloc routine was changed to check only the
3484 All silc_cipher_* routines that used to return int returns
3487 The affected files lib/silccrypt/silccrypt.[ch].
3489 * The same thing was done to silc_hash_* as for silc_cipher_*
3490 routines. Affected files lib/silccrypt/silchash.[ch].
3492 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3493 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3494 Added also silc_pkcs_[un]register[_default] functions.
3495 Removed the data_context from the PKCS API.
3497 * Added silc_hmac_register_default function to register default
3498 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3499 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3500 to unregister all hmacs at once.
3502 * Register the default ciphers, hash functions, PKCSs and HMACs
3503 if client's configuration file does not exist. The affected
3506 * The client did not load the hash functions from the SIM
3507 modules at all. Added support for this. Affected file is
3508 silc/clientconfig.c.
3510 * When decoding public key with silc_pkcs_public_key_decode, check
3511 the supported algorithm only if PKCS are registered. Affected
3512 file lib/silccrypt/silcpkcs.c. The same was done with the
3513 silc_pkcs_private_key_decode.
3515 * Fixed the SILC List routines to keep the list always in order.
3516 It used to change the list's order when traversing the list but
3517 not it preserves the order. Affected file lib/trq/silclist.h.
3519 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3521 * Added the client library to use the SilcSocketConnection's
3522 reference counter (by silc_socket_dup) to prevent the bug that
3523 the socket object may be freed underneath async operation.
3525 * The name resolv library checking fixes in the configure.in.pre.
3528 * Created new version of the protocol drafts for future
3529 development. The -03 drafts are the ones that will be changed
3530 in the trunk now and the -02 will remain as they are.
3532 * Send list of CUMODE notifys to the router when announcing
3533 the channel users to the router. Affected file silcd/server.c.
3534 If the router receiving channel founder CUMODE for a channel
3535 that already has channel founder it will send CUMODE notify
3536 to the sender to remove the channel founder rights from the
3537 announced client. Affected file silcd/packet_receive.c.
3539 * The CUMODE notify may now use Server ID as well as the entity
3540 who changes the mode. Updated protocool specs.
3542 * Updated INSTALL and README files.
3544 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3546 * New web pages in the http://silc.pspt.fi. The pages was
3551 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3553 * Implemented the [DenyConnectin] config section in the server.
3554 Added silc_server_config_denied_conn to check whether incoming
3555 connection is denied. Affected file silcd/serverconfig.[ch].
3557 * Do not check the ports when checking the incoming configuration
3558 data if the port is 0, meaning any. Affected file is
3559 silcd/serverconfig.c.
3561 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3563 * Fixed buffer overflow in silc_string_compare in the file
3564 lib/silcutil/silcutil.c.
3566 * Fixed double free in silc_server_command_leave in the file
3569 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3571 * Fixed the version checking in the server. Affected file is
3574 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3576 * Fixed the configuration data fetching when accepting new
3577 connections in the server. Affected file silcd/server.c.
3579 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3581 * Added `sender_entry' argument to the function
3582 silc_server_packet_relay_to_channel so that we can check
3583 whether some destination actually belongs to the same route
3584 the sender belongs (ie, we must not resend the packet to the
3585 sender). Affected file silcd/packet_send.[ch].
3587 * Added `servername' field to the SilcClientEntry in the server
3588 to hold the name of the server where client is from. Affected
3589 file is silcd/idlist.h.
3591 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3593 * Moved the channel message encrypting in the router betwen
3594 router connections from silc_server_channel_message to the
3595 silc_server_packet_relay_to_channel since we want to check
3596 whether we have anybody channel before encrypting anything.
3597 Affected files silcd/packet_[receive/send].c.
3599 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3601 * Fixed the [AdminConnection] server config section to support
3602 multiple entries. Affected file silcd/serverconfig.c.
3604 * Added support into the server to check the validity of the
3605 incoming connection before executing any KE or authentication
3608 * The connection configuration is now saved to the KE and
3609 connection auth protocol contexts and not fetched anymore in
3610 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3612 * The local hosts listenning address and port is also resolved
3613 now when starting the server. We want to have the socket object
3614 to include the real address and port for the listener. Added
3615 new function silc_net_check_local_by_sock into the files
3616 lib/silcutil/silcnet.[ch].
3618 * Fixed a broadcast bug in server -> do not broadcast if we
3621 * Fixed a routing bug. Do not route broadcast packets ever.
3622 Broadcast packets must be processed always and not routed since
3623 they may be destined to some other host than yourself and thus
3624 would get routed without no good reason. Affected file is
3627 * Added function silc_server_config_is_primary_route to check
3628 whether primary router connection has been configured (a router
3629 configuration that we are initiating). If there is not, we
3630 will assume that there is only two routers in the SILC network
3631 and we will use the incoming router connection as our primary
3632 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3634 * Changed the order of the broadcasting. Broadcast _after_ the
3635 packet has been processed not before. Affected file is
3638 * Fixed a [ClientConnection] parsing bug. The port was never
3639 parsed correctly thus resulting to port 0. Affected file
3640 silcd/serverconfig.c.
3642 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3643 argument and did not set the broadcast packet flag. Affected
3644 file silcd/packet_send.c. Fixed same bug in the function
3645 silc_server_send_notify as well.
3647 * If we receive NEW_ID packet for our own ID in the server, ignore
3650 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3654 * Removed the nickname from the Private Message Payload.
3655 Updated the code and the protocol specs.
3657 * Updated protocol specs for submitting to the IETF.
3659 * Tweaked the Random Number Generator a bit. Affected file
3660 lib/silccrypt/silcrng.c. Exported a new function
3661 silc_rng_[global]_add_noise which can be used to add more
3664 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3666 * Do not parse packets with different timeout when protocol
3667 is active -> may cause problem with rekey. Affected file
3670 * When server receives signoff notify it must not create
3671 new channel key if the client is on any channels since the
3672 sender of the signoff notify will create it.
3674 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3676 * Added printing of error messages during SKE protocol from the
3677 failure packet sent by server during SKE. Affected file
3680 * Removed the client's failure_callback handling with timeout
3681 and handle it immediately when received.
3683 * The SKE library returned wrong type in SUCCESS and FAILURE
3684 packets. They must be 32 bit MSB not 16 bit MSB.
3686 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3688 * Ok, rewrote the logic of the re-key and now it seems to work.
3689 I tested it on high traffic with frequent re-keys without
3690 problems. Added hmac_receive (and renamed hmac to hmac_send)
3691 in SilcClientConnection in lib/silcclient/client.h and
3692 in SilcIDListData in silcd/idlist.h. Also, removed the
3693 SilcPacketParserContext's cipher and hmac fields as they are
3694 not needed anymore and actually caused some problems when
3695 the ciphers and hmac's changed underneath the packet parser.
3697 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3699 * If re-key protocol is active then process the incoming packets
3700 synchronously since we must assure that icoming packets encrypted
3701 with the old key is processed before the new keys is set to
3702 use. This is true other packets than for REKEY packets.
3703 Affected file silcd/server.c. The same was done to client library
3704 as well, affected file lib/silcclient/client.c.
3706 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * Fixed bug in client and server to accept the force send if
3709 the packet is send from silc_[server/client]_packet_process
3710 function. Otherwise the packets are never delivered, oops.
3712 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3714 * Disable force sending of packets when REKEY protocol is active.
3715 We must assure that no packet is sent directly when rekey is
3716 performed. All packets must be sent through packet queue.
3717 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3718 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3719 function is silc_[server/client]_packet_send_real to check
3722 * Replaced the SIM paths from example config files to
3723 /usr/local/modules. Also, make install creates now

3738 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3740 * When MAC computation fails the silc_packet_decrypt returned 0
3741 even though it was supposed to return -1. Fixed this. The
3742 affected file is lib/silccore/silcpacket.c.
3744 * Do not replace the config files in /etc/silc (in make install)
3745 if they already exist. Affected file ./Makefile.am.
3747 * Do not send re-key packets immediately but through packet queue.
3748 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3750 * Changed silc_net_check_host_by_sock to return FALSE if the

3763 contents of the specified public key file.
3765 * Changed the PKCS api to return the public key length when
3766 setting the public key.
3768 * Fixed a fatal bug in the public and private key file loading.
3769 Affected file lib/silccrypt/silcpkcs.c.
3771 * Execute the packet parsing for client with zero (0) timeout
3772 if the protocol is active. Affected file silcd/server.c.
3774 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3776 * Made the key generation options to the silcd program. Added
3777 -C option, equivalent to client's option.
3779 * Added new [ServerKeys] config section to the server. It
3780 configures the server's public and private key.
3782 * Defined generic Public Key Payload into the protocol
3783 specification to send specific type of public keys and
3786 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3787 public key or certificate.
3789 * Implemented the GETKEY command to the server and to the

3794 * Made preliminary `make install' work.
3796 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3798 * Added SilcServerRekey context into silcd/idlist.h.
3800 * Added the PFS support as defined in the specification to the
3801 SKE protocol. Affected files lib/silcske/*.c.
3803 * Added `ske_group' field to the SilcServerRekey context to hold
3804 the number of the SKE group that is used with PFS in re-key.
3805 Affected file silcd/idlist.h.
3807 * Added PFS re-key support to the server. Affected file is
3810 * Added silc_protocol_cancel to cancel execution of the next
3811 state of the protocol. Affected file is
3812 lib/silccore/silcprotocol.[ch].
3814 * Added the re-key support with and without PFS to the client
3815 library. Re-key is performed once in an hour, by default.
3817 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3818 Added silc_client_rekey_callback and silc_client_rekey_final.
3819 Affected files are lib/silcclient/protocol.[ch] and
3820 lib/silcclient/client.[ch].
3822 * Removed the `hmac_key' and `hmac_key_len' fields from the
3823 SilcClientConnection structure; not needed. Affected file is

3828 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3830 * Do not ask whether user wants to use the negotiated private key
3831 for private messages, just use it. Affected file is
3832 silc/local_command.c.
3834 * Added `send_enc_key' and `enc_key_len' fields to the
3835 SilcIDListData structure since they are needed in the re-key
3836 phase. Affected file is silcd/idlist.[ch].
3838 * Implemented the simple re-key protocol into the server.
3839 Affected files silcd/server.c and silcd/protocol.[ch]. The
3840 re-key will be performed once in an hour, by default.
3842 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3843 Added silc_server_rekey, silc_server_rekey_callback and
3844 silc_server_rekey_final.
3846 * Removed Tunneled flag from the protocol. Updated the code
3847 and the specifications.
3849 * Adde `pfs' field to the SilcIDListData to indicate whether
3850 the PFS is to be performed in the re-key. Affected file is
3853 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3855 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3856 int64 of at least the xintXX size. If void * is less that 4
3857 bytes uint32 * will be used. Defined bool as boolean.
3859 * Changed _ALL_ unsigned long and unsigned int to uint32,
3860 unsgined short to uint16 in the source tree.
3862 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3863 not handle clients that has entry->data.registered == FALSE.
3864 They are not in the network anymore. Affected file is
3867 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3869 * Implemented the sending of the SERVER_SIGNOFF notify in the
3870 server. Affected file is silcd/server.c.
3872 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3873 Added also silc_notify_payload_encode_args into the
3874 lib/silccore/silcnotify.[ch].

3877 Affected file silcd/packet_receive.c.
3879 * Implemented the SERVER_SIGNOFF notify handling in the client
3880 library. Affected file lib/silcclient/client_notify.c. Also,
3881 implemnted the printing of the SERVER_SIGNOFF info to the
3882 application. Affected file silc/client_ops.c.
3884 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3885 if the deleting was successful. Affected file silcd/idlist.[ch].
3887 * Added support for public key authentication in the connection
3888 authentication protocol in the client library. Affected file
3889 lib/silcclient/protocol.c.
3891 * Changed the server's silc_idlist_get_clients_by_* interface
3892 to support already allocated array so that new entries may be
3893 added to pre-allocated array. Affected file silcd/idlist.[ch].
3894 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3895 and command replies.
3897 * All command reply functions in the server now calls the
3898 pending command callback even if error occured. This way the
3899 error will be delivered to the client as well. Affected files
3900 silcd/command.c and silcd/command_reply.c.
3902 * Fixed INFO command to return local server's info if no server
3903 was provided. Affected file lib/silcclient/command.c.
3905 * Removed RESTART command for good. Updated the code and the
3908 * Rewrote parts of the task system. It is a bit simpler now.
3909 Removed unsued task priorities. The affected files are
3910 lib/silcutil/silctask.[ch].
3912 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3914 * Moved the USERS printing from the library to the application.
3915 Affected files lib/silcclient/command.c and silc/client_ops.c.
3917 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3921 * Added channel key re-key support. The re-key is perfomed
3922 only by the router and is done once in an hour. Added `rekey'
3923 field to the SilcChannelEntry in the server. Affected files
3924 silcd/server.c and silcd/idlist.h.
3926 * Added silc_task_unregister_by_context into the file
3927 lib/silcutil/silctask.[ch].
3929 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3931 * Added SILC_UMODE_GONE mode to indicate when the client is not
3932 present in the SILC network. Added also support to the local
3933 command AWAY that will set this mode. Added support of showing
3934 "xxx is gone" in WHOIS command. The USERS command shows the
3935 gone status as well.
3937 * Fixed setting server and router operator privileges in the
3938 server's UMODE command. Affected file silcd/command.c.
3940 * Merged the SKE KE1 and KE2 payloads into one payload. The
3941 new KE payload is equivalent to the old KE2 payload.
3943 Cleaned up the SKE Start Payload parsing. It now uses the
3944 simple buffer unformatting to do the parsing. A lot faster
3947 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3948 to the SKE that is used to indicate whether both of the SKE
3949 parties should perform authentication. By default only the
3950 responder performs authentication. By setting this flag also
3951 the initiator must do authentication. By default it is unset
3952 since in normal SKE case, client to server connection, only
3953 the responder should do authentication. When doing SKE between
3954 two clients both should perform authentication. Updated the
3955 code and the protocol specs.
3957 * A little fix to IDENTIFY command in the server. Search the
3958 client first by hash not nickname. Affected file is
3961 * Fixed the silc_client_close_connection to support closing
3962 the client to client connections wihtout deleting too much
3963 data. Affected file lib/silcclient/client.c.
3965 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3966 are received if protocol used to be active but is not anymore
3967 the application would crash due to NULL pointer dereference.
3968 Affected files silcd/server.c and lib/silcclient/client.c.
3970 * Added `hash' field to the SilcClientConnection to include
3971 the hash function negotiated in the SKE protocol.
3973 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3974 to set the channel founder authentication data. A client can
3975 claim the founder rights later by providing the authentication
3976 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3977 This way the channel founder can regain the channel founder
3978 privileges even it is left the channel. This works only on
3979 local server and the client must be connected to the same
3980 server to be able to regain the founder rights. Updated the
3981 protocol specs accordingly.
3983 Added support to the CMODE command in the client to set the
3984 founder auth data. Read the README to see how to set it.
3986 Added support to the CUMODE command to claim the founder
3987 rights. Read the README to see how to do it.
3989 Added support for the founder authentication to the Channel
3990 Entry in the server. Affected file silcd/idlist.h.
3992 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3993 server's CMODE command. Affected file silcd/command.c.
3995 * Added the following new functions into lib/silccore/silcauth.[ch]:
3996 silc_auth_get_method and silc_auth_get_data.
3998 * The server now saves the remote hosts public key to the
3999 SilcIDListData pointer. Affected file silcd/protocol.c.
4001 * The normal server now does not remove the channel entry from
4002 the cache if the founder authentication data is set. It used
4003 to remove it if the founder was the last one on the channel on
4004 the server and left the channel. The auth data is saved and
4005 if the channel is re-joined later the old entry is used with
4006 the old auth data. Affected files silcd/command_reply.c and
4009 * Removed the `pkcs' field from the SilcIDListData structure
4010 in the server; it is not used. Affected file silcd/idlist.h.
4012 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Fixed packet processing on slow links. Partial packets were
4015 never re-processed because the incoming data buffer was cleared
4016 by the application. Application must not directly clear the
4017 sock->inbuf, the packet processing routines handle it. Fixed
4018 this in client library and in server.
4020 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4022 * Fixed the WHOIS and IDENTIFY send reply function to really
4023 check whether to send list or just one entry. Affected file
4026 * Cleaned up the LEAVE command's channel key distribution. The
4027 affected file silcd/command.c.
4029 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4030 can enforce the channel mode as well. In that case the ID
4031 includes the ID of the server. The code now enforces the
4032 mode change if the router have different mode than the server.
4034 * The notify client operation with CMODE_CHANGE notify can now
4035 return NULL client_entry pointer if the CMODE was not changed
4036 by client. Application must check for this.
4038 * Added <Server ID> argument to INFO command to support server
4039 info fetching by Server ID.
4041 * Added silc_server_announce_get_channel_users to get assembled
4042 packets of channel users of the specified channel. Affected
4043 file silcd/server.[ch].
4045 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4046 was freed underneath the ID Cache.
4048 * Re-announce clients when the server received CHANNEL_CHANGE
4049 notify from the router. Affected file silcd/packet_send.c.
4051 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4053 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4054 crashed since it did not handle the fact that there is no cipher
4055 called "3" and didn't check the error condition. Now fixed.
4057 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4058 flag. It can be used to send message requests.
4060 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4062 * Implemented the RESTART command in the client.
4064 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4065 notice type messages. Added notice printing to the user
4068 * The channel keys are not re-generated if the channel's mode
4069 is PRIVKEY, ie private key on the channel exists. Affected
4070 files silcd/server.c and silcd/command.c.
4072 * Fixed a little bug in channel message delivery when channel
4073 private keys are set in the server. Affected file is
4074 silcd/packet_send.c.
4076 * Changed the setting on channel->on_channel = TRUE from the
4077 silc_client_save_channel_key to the JOIN command reply. The
4078 key payload is not received if the private channel key is set.
4079 Affected file lib/silcclient/command_reply.c and the
4080 lib/silcclient/client_channel.c.
4082 * When the CMODE_CHANGE notify is sent and the channel private
4083 key mode is removed the channel key must be re-generated in
4084 other cells as well. Added this support for the router in the
4085 silcd/packet_receive.c.
4087 * Added new local command NOTICE to send notice message on
4088 channel. Affected file silc/local_command.[ch].
4090 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4092 * Added new local command ME to the client. It is used to send
4093 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4094 some action. Affected file silc/local_command.[ch].
4096 * Changed channel_message and private_message client operations
4097 to deliver the message flags to the application. Added also
4098 the `flags' arguments to the silc_client_send_channel_message
4099 and silc_client_send_private_message functions. Affected file
4102 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Redefined the Private Message Payload to support private message
4105 keys and to support the new private message flags. Updated
4106 the protocol specs. Flags makes it possible to have for example
4107 CTCP style messages.
4109 * Added new type SilcPrivateMessagePayload and defined an API
4110 for it in the lib/silcclient/silcprivate.[ch].
4112 * Tested private message private keys successfully. Tested the
4113 private message key set, unset and list commands with the new
4116 * Redefined the Channel Message Payload to include the channel
4117 message flags (equal with private message flags) to support
4118 for example CTCP style messages.
4120 * Defined some of the message (for channel and private message)
4121 flags. Updated the protocol specs and added the flags to the
4122 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4124 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4126 * Added SilcKeyAgreementStatus type to the key agreement routines
4127 to indicate the current status and error if one occured.
4128 The status types are defined in the lib/silcclient/silcapi.h.
4130 * Added new local command KEY that is used to set and unset private
4131 keys for channels, set and unset private keys for private messages
4132 with remote clients and to send key agreement requests and
4133 negotiate the key agreement protocol with remote client. The
4134 key agreement is supported only to negotiate private message keys,
4135 it currently cannot be used to negotiate private keys for channels,
4136 as it is not convenient for that purpose.
4138 * Fixed a minor pending callback setting bug in the function
4139 silc_client_get_client_by_id_resolve, now the function works.
4140 Affected file lib/silcclient/idlist.c.
4142 * Added function silc_net_get_local_port to get local bound
4143 port by socket. Added to lib/silcutil/silcnet.[ch].
4145 * Added `sockets' and `sockets_count' fields to the SilcClient
4146 object. They hold the sockets of the listenning sockets in
4147 the client. Listenning sockets may be for example the key
4148 agreement server. Affected file lib/silcclient/client.[ch].
4149 Added functions the silc_client_add_socket and the
4150 silc_client_del_socket. They are exported to the application
4153 * Added ~./silc/clientkeys to support other client's public keys.
4155 * Renamed verify_server_key client operation to verify_public_key
4156 and added one argument to indicate the type of the connection
4157 (server, client etc.).
4159 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4161 * Added silc_server_connection_auth_request to handle the
4162 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4163 silcd/packet_receive.[ch].
4165 * Added silc_server_send_connection_auth_request into the
4166 silcd/packet_send.c to send the connection auth request packet.
4168 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4171 * Fixed the public key authentication in responder side in the
4172 server. The `auth_data' pointer includes the SilcPublicKey
4173 not the path to the public key. Affected file silcd/protocol.c.
4175 * Implemented the public key authentication in the initiator side
4176 in the server. Affected file silcd/protocol.c.
4178 * Removed the [RedirectClient] config section from the server
4179 configuration. Is not needed and I don't want to implement it.
4181 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4183 * Cleaned up the CMODE command in the server. It now works
4184 correctly and supports all the modes defined in the protocol.
4185 Affected file is silcd/command.c.
4187 * Added `hmac_name' field to the SilcChannelEntry in the server
4188 to hold the default HMAC of the channel. It can be set when
4189 creating the channel (with JOIN command). Affected files
4192 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4193 type to indicate the change of the current cipher and hmac
4194 on the channel. Client can safely ignore the <cipher> argument
4195 (if it chooses to do so) since the CHANNEL_KEY packet will
4196 force the channel key change anyway. The <hmac> argument is
4197 important since the client is responsible of setting the new
4198 HMAC and the hmac key into use.
4200 * Fixed the CMODE command in the client library as well.
4202 * Tested CMODE command in router environment successfully.
4204 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4206 * Show the version of the remote client (or server) when connecting
4207 to the server. It is logged to the log file. Affected file
4208 is silcd/protocol.c.
4210 * Fixed the KILLED notify handling in the client library. The
4211 client must be removed from all channels when receiving the
4214 Also, do not remove the client entry when giving the KILL
4215 command but when the KILLED notify is received.
4217 * Removed silc_idlist_find_client_by_nickname from the server.
4218 Not needed anymore. Affected files silcd/idlist.[ch].
4220 * Implemented the CHANNEL_CHANGE notify type handling to the
4221 server. Affected file silcd/server.c.
4225 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4227 * Added silc_server_send_notify_invite to send the INVITE
4228 notify between routers.
4230 * Implemented the INVITE command correctly to the server.
4232 * Implemented the INVITE notify type handling in the server.
4234 * Implemented the INVITE command to the client library and on the
4237 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4239 * Added function silc_server_get_client_resolve to find the
4240 client entry by ID from all ID lists and then resolve it
4241 (using WHOIS) if it cannot be found. Affected file is
4244 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4246 * Implemented the BAN command to the client library.
4248 * The JOIN command in the server now checks the invite list
4251 * Changed the silc_command_reply_payload_encode_va and the
4252 silc_command_payload_encode_va to support that if argument is
4253 NULL it ignores and checks the next argument. Affected file
4254 lib/silccore/silccommand.c.
4256 * Added silc_server_send_notify_ban to send the BAN notify
4257 type between routers.
4259 * Chaned the silc_notify_payload_encode to support that if
4260 argument is NULL it ignores and checks the next argument.
4261 Affected file lib/silccore/silcnotify.c.
4263 * Tested ban lists in router environment successfully.
4265 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Implemented BAN command to the server, in silcd/command.[ch].
4269 * Removed the BAN and INVITE_LIST modes from the CMODE command
4272 * Added function silc_string_match to regex match two strings.
4273 Affected files lib/silcutil/silcutil.[ch].
4275 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4277 * Redefined parts of the SilcChannelEntry in the server to support
4278 the new ban and invite lists.
4280 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4282 * Redefined the INVITE command. The same command can be used to
4283 invite individuals to the channel but also to manage the invite
4284 list of the channel (to add to and remove from the invite list).
4285 Updated the protocol specs.
4287 * Added new command SILC_COMMAND_BAN that can be used to manage
4288 the ban list of the channel. Updated the protocol specs.
4290 * Removed the channel modes: the SILC_CMODE_BAN and the
4291 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4292 in the CMODE command. The equivalent features are now available
4293 using INVITE and BAN commands. Updated the protocol specs.
4295 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4296 in the network about change in the current ban list. The notify
4297 type is not used by the client.
4299 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4300 support the invite lists.
4302 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * Added new function silc_string_regexify that converts string
4305 including wildcard characters into regex string that can
4306 be used by the GNU regex library. Added into the file
4307 lib/silcutil/silcutil.[ch].
4309 Added silc_string_regex_combine to combine to regex strings
4310 into one so that they can be used as one regex string by
4311 the GNU regex library. Added into the file
4312 lib/silcutil/silcutil.[ch].
4314 Added silc_string_regex_match to match two strings. It returns
4315 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4317 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4319 * Imported GNU regex to the soruce tree into lib/contrib.
4320 Fixed some compiler warning from the regex.c.
4322 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4324 * Fixed MOTD command in the server to work in router environment.
4326 * Fixed the MOTD command in the client library to support
4327 the server argument in the command.
4329 * Added `nickname_len' argument to the silc_idlist_add_client
4330 in the server, as the `nickname' argument may be binary data
4333 * Added silc_idlist_get_channels to return all channels from
4336 * Implemented LIST command to the server. Affected file is
4339 * Implemented the LIST command to the client library and on the
4342 * Added [<user count>] argument to the LIST command reply.
4343 With private channels the user count is not shown.
4345 * Updated TODO and README.
4347 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4349 * The client entry's data.registered must be TRUE even with
4350 global client entry on global client list. The data.registered
4351 is used to check whether the client is anymore in the network,
4352 for example with WHOWAS command so it must be valid.
4354 * Fixed the WHOWAS command in the server. It now actually works
4355 in router environment. Added function into silcd/command_reply.c
4356 silc_server_command_reply_whowas_save.
4358 * Added silc_idlist_purge function to the silcd/idlist.c
4359 to periodically purge the ID Cache.
4361 * Fixed INFO command in the server. It works now in router
4362 environment. Added <server name> argument to the INFO command
4363 reply. Updated the protocol specs.
4365 * Fixed minor bug in silc_idcache_purge to not purge if the
4366 expire value is zero.
4368 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4369 they were buggy because of the WHOWAS information.
4371 * Fixed local command MSG to handle the async resolving of
4372 the remote client properly. It used to fail the first MSG.
4373 Affected file silc/local_command.c.
4375 * Added `data_len' field to SilcIDCache context.
4377 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4379 * Update TODO. Todo in commands in the server.
4381 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4384 used by routers as broadcast packet to inform other routers
4385 about the changed user mode.
4387 Implemented the notify handling in the server. Affected file is
4388 silcd/packet_receive.c. Added the function
4389 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4391 * Added new generic Channel Payload and deprecated the New Channel
4392 Payload. The New Channel Payload is now the generic Channel
4395 * Added new argument `mode' to the silc_server_send_new_channel
4396 as it is required in the Channel Payload now.
4398 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4399 and created a new and real SilChannelPayload to represent the
4400 new generic Channel Payload. Implemented the encode/decode
4401 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4403 * Added silc_server_get_client_channel_list to return the list
4404 of channels the client has joined for WHOIS command reply.
4405 Affected file silcd/server.[ch].
4407 * Implemented the channel list sending in the WHOIS command reply
4408 in server and in the client.
4410 Implemented the channel list displaying on the user interface
4411 as well. Affected file silc/client_ops.c.
4413 * Added silc_channel_payload_parse_list to parse list of Channel
4414 Payloads. It returns SilcDList list of SilcChannelPayloads.
4415 Client for example can use this function to parse the list of
4416 channels it receives in the WHOIS command reply. The caller
4417 must free the list by calling silc_channel_payload_list_free.
4418 Affected files lib/silccore/silcchannel.[ch].
4420 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Added one new argument <user mode> to the WHOIS command reply
4423 to return the mode of the user in SILC. Updated the protocol
4426 Implemented it to the server and client.
4428 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4430 * Fixed the mode printing on the user interface on joining.
4431 Affected file silc/client_ops.c.
4433 * Implemented the UMODE command and user modes in general to the
4434 client library and to the user interface.
4436 * Implemented the UMODE command to the server.
4438 * The server now sends UNKNOWN_COMMAND error status if client sends
4439 unknown command. Affected file silcd/command.c.
4441 * All server commands now handle the command identifier the right
4442 way when sending the command reply to the client. The client can
4443 use to identify the command replies with the identifier.
4445 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4447 * Added silc_server_get_client_route to resolve the route to
4448 the client indicated by the client ID. Affected file is
4451 * Added silc_server_relay_packet as general function to relay
4452 packet to arbitrary destination. This deprecates functions
4453 like _send_private_message_key, _relay_notify etc. Affected
4454 file is silcd/packet_send.[ch].
4456 Removed silc_server_send_key_agreement,
4457 silc_server_send_private_message_key and
4458 silc_server_packet_relay_notify functions from the file
4459 silcd/packet_send.[ch].
4463 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4464 server. Affected file silcd/packet_receive.[ch].
4466 * Implemented the KILL command to the client. Implemented the
4467 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4468 Affected files lib/silcclient/command[_reply].c and
4469 lib/silcclient/client_notify.c. Implemented the KILL notify
4470 printing in the user inteface.
4472 * Fixed a lot silc_parse_nick memory leaks from the client
4473 library in the file lib/silcclient/command.c.
4475 * Changed the silc_server_send_notify_on_channels's `sender'
4476 argument from SilcSocketConnection to SilcClientEntry to
4477 check the sender as entry and not as connection object and not
4478 to send to the client provided as argument. The affected file
4479 is silcd/packet_send.[ch].
4481 * The notify packets that are destined directly to the client used
4482 to not to be processed by the server. Now changed that and the
4483 server processes all notify packets. After relaying the packet
4484 to the client the notify packet is processed in the server.
4486 * The silc_server_free_client_data now checks whether there is
4487 pending outgoing traffic for the client and purges the data to
4488 the network before removing the client entry.
4490 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4492 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4493 an client is killed from the SILC Network. Updated the protocol
4496 Added new function silc_server_send_notify_killed to the
4497 silcd/packet_send.[ch].
4499 * Added function silc_server_packet_relay_notify to relay notify
4500 packets that are destined directly to a client. In this case
4501 the server does not process the notify packets but merely relays
4502 it to the client. Affected file silcd/packet_send.[ch].
4504 Added also silc_server_packet_process_relay_notify to check
4505 whereto relay the notify. Affected file is
4506 silcd/packet_receive.[ch].
4508 * Implemented the KILL command to the server.
4512 * Added the backup schema desgined last fall to the protocol
4513 specs for everyone to see. The specification is in the
4514 *-spec-xx.txt draft and the packet type definitions for the
4515 backup routers is in *-pp-xx.txt draft. Thusly, added also
4516 new packet type SILC_PACKET_CELL_ROUTERS.
4518 * A big security problem in the implementation discovered. The
4519 signoff of an client did not cause new channel key generation
4520 which it of course should've done. The channel keys must be
4521 always re-generated when client leaves (or signoffs) the channel.
4522 The silc_server_remove_from_channels funtion now handles
4523 the channel key re-generation.
4525 * Added `sender' argument to the silc_server_send_notify_on_channels
4526 to not to send the client provided as argument. Affected file
4527 silcd/packet_send.[ch].
4529 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Implemented OPER and SILCOPER commands into the server and
4534 * Added silc_auth_verify and silc_auth_verify_data to verify
4535 the authentication directly from the authentication payload.
4536 It supports verifying both passphrase and public key based
4537 authentication. Affected file lib/silccore/silcauth.[ch].
4539 * Added `hash' field to the SilcIDListData structure. It is the
4540 hash negotiated in the SKE protocol. Affected file is
4543 * Slight redesigning of the SilcAuthPayload handling routines.
4544 Do not send SilcPKCS but SilcPublicKey as argument.
4546 * Implemented the public key authentication support to the
4547 serverconfig. The public key is loaded from the provided path
4548 and saved as authentication data to void * pointer. Thus,
4549 changed the unsigned char *auth_data to void *auth_data;
4551 * Fixed SHUTDOWN command to send the reply before the server
4552 is shutdown. :) Affected file silcd/command.c.
4554 * Fixed fatal bug in CONNECT command. The hostname was invalid
4555 memory and server crashed. Affected file silcd/command.c.
4557 * Fixed fatal bug in CLOSE command. The server_entry became
4558 invalid but was referenced later in the command. Affected file
4561 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4563 * Fixed fatal bug in failure packet handling. Server ignored
4564 the failure and thus crashed when it came.
4568 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4570 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4571 that the command may be executed only once in (about) 2 seconds.
4572 The old SILC_CF_LAG flag is same but allows command bursts up
4573 to five before limiting.
4575 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4576 server code. Various commands now includes the CF_LAG_STRICT
4577 flag to disallow any kind of miss-use of the command.
4579 * Fixed the silc_buffer_unformat to not to allocate any data
4580 if the length of the data is zero. It used to allocate the
4581 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4583 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * Changed the format of AdminConnection configuration section
4586 in the server. Added username of the admin to the format.
4587 Affected files silcd/serverconfig.[ch].
4589 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4590 to return admin configuration data by host, username and/or
4593 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4595 * Implemented WHOWAS command to the server. Added the functions:
4597 silc_server_command_whowas_parse,
4598 silc_server_command_whowas_send_reply,
4599 silc_server_command_whowas_from_client and
4600 silc_server_command_whowas_from_server
4602 * Added <Client ID> argument to the WHOWAS command reply. Updated
4603 the protocol specs accordingly.
4605 * Implemented WHOWAS command and command_reply to the client
4608 Implemented the WHOWAS printing on the user interface.
4610 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4612 * Added new argument to the WHOWAS command reply, the real name.
4613 It is an optional argument. Updated the protocol specs.
4615 * Added SilcIDCacheDestructor callback that is registered when
4616 the SilcIDCache is allocated. The callback is called when
4617 an cache entry in the ID Cache expires, or is purged from the
4618 cache. Added into lib/silccore/idcache.[ch].
4620 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4621 to destruct the client entries when the cache entry expires.
4622 Other ID Cache's in server and in the client library ignores
4625 * If the ID Cache entry's `expire' field is zero then the entry
4626 never expires. Added boolean `expire' argument to the
4627 silc_idcache_add function in the lib/silccore/idcache.[ch].
4628 If it is TRUE the default expiry value is used.
4630 * Added silc_server_free_client_data_timeout that is registered
4631 when client disconnects. By default for 5 minutes we preserve
4632 the client entry for history - for WHOWAS command.
4634 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4636 * Added support to the server to enforce that commands are not
4637 executed more than once in 2 seconds. If server receives
4638 commands from client more frequently, timeout is registered
4639 to process the commands. Affected file silcd/command.c.
4640 Added new function silc_server_command_process_timeout.
4642 * Changed NICK_NOTIFY handling in client library to check that
4643 if the client's nickname was changed, so there is no need to
4644 resolve anything from the server.
4646 * Removed error printing from the WHOIS and IDENTIFY commands.
4647 If error occurs then it is ignored silently in the client library.
4648 The application, however, may map the received error to
4649 human readable error string. The application currently maps
4650 the NO_SUCH_NICKNAME error to string.
4652 * Made the command status message public to the application. Moved
4653 them from lib/silcclient/command_reply.c to
4654 lib/silcclient/command_reply.h. The application can map the
4655 received command status to the string with the
4656 silc_client_command_status_message function.
4658 * Added check to the server to check that client's ID is same
4659 as the Source ID in the packet the client sent. They must
4662 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4664 * Added dist-bzip hook to the Makefile.am to make bzip2
4665 compressed distributions.
4667 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4669 * Server now enforces the maximum length for the nickname and
4670 the channel as protocol specification dictates. 128 bytes for
4671 nickname and 256 bytes for channel name.
4673 * Moved the WHOIS printing to the application. The client libary
4674 does not print out the WHOIS information anymore, the application
4675 must do it. Renamed silc_client_command_reply_whois_print to
4676 the silc_client_command_reply_whois_save.
4678 The client's idle time is also sent to the application now, and
4679 the idle is shown on screen.
4681 * Added silc_client_command_reply_identify_save to save the
4682 received IDENTIFY entries.
4684 * Do not check for channel private keys in message sending and
4685 reception if the channel does not have the PRIVKEY mode set.
4686 Affected file lib/silclient/client_channel.c.
4688 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4690 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4691 just surfaced after chaning the JOIN procedure.
4693 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4695 * Added silc_client_get_clients_by_list to get client entries
4696 from Client ID list, that is returned for example by JOIN
4697 and USERS command replies. The application should use this
4698 function for example when JOIN command reply is received to
4699 resolve the clients already on the channel (library does not
4700 do that anymore as USERS command reply is not used in the JOIN
4701 procedure anymore). Affected files lib/silcclient/silcapi.h and
4702 lib/silcclient/idlist.c.
4704 * JOIN command reply and USERS command reply returns now SilcBuffer
4705 pointers instead of unsigned char pointers when returning
4706 the client list and mode list.
4708 * Added <Client ID> argument to the JOIN command reply, mainly
4709 for the server to identify for which client the command was
4710 originally sent. Updated protocol specs accordingly.
4712 * Added SilcDlist private_key pointer to the SilcChannelEntry
4713 in the client to support the channel private keys. Affected
4714 file is lib/silcclient/idlist.h.
4716 * Added SilcChannelPrivateKey argument to the function
4717 silc_client_send_channel_message so that application can choose
4718 to use specific private ke if it wants to. If it is not provided,
4719 the normal channel key is used, unless private keys are set.
4720 In this case the first (key that was added first) is used
4721 as the encryption key.
4723 * Implemented the support for channel private key handling.
4724 Implemented the following functions:
4726 silc_client_add_channel_private_key,
4727 silc_client_del_channel_private_keys,
4728 silc_client_del_channel_private_key,
4729 silc_client_list_channel_private_keys and
4730 silc_client_free_channel_private_keys
4732 Affected file lib/silcclient/client_channel.c.
4734 * Added the support for the private keys in the channel message
4735 sending and encryption and in the message reception and
4736 decryption. Affected funtions are
4737 silc_client_send_channel_message and silc_client_channel_message.
4739 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4741 * Added SKE's key verify callback to the client library's
4742 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4744 * Removed the statement that server (or router) must send USERS
4745 command reply when joining to the channel so that the client
4746 knows who are on the channel. Instead, the client list and
4747 client's mode list is now sent in the JOIN command reply to the
4748 client who joined channel. This is better solution.
4750 * Added function silc_server_get_users_on_channel and function
4751 silc_server_save_users_on_channel to the silcd/server.[ch].
4753 * Removed function silc_server_command_send_users from the
4756 * Do not show topic on the client library anymore. The topic is
4757 sent in the command reply notify to the application and the
4758 application must show the topic now.
4760 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4762 * Added client searching by nickname hash into the IDENTIFY and
4763 WHOIS commands in the server as they were clearly missing from
4764 them. Affected file is silcd/command.c.
4766 * Fixed a bug in private message receiving in the client library.
4767 The remote ID was freed and it wasn't supposed, now it is
4770 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4772 * Minor fix to the channel payload; allocate the data area, as it
4773 needs to be of specific length.
4775 * If the key agreement port is zero then the operating
4776 system will define the bound port. Affected files are
4777 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4779 * Added new function silc_channel_payload_decrypt into the file
4780 lib/silccore/silcchannel.[ch].
4782 * Moved the channel message etc, check from silc_packet_decrypt
4783 to applications. The library calls now a generic
4784 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4785 when the packet is either normal or special. This was done to
4786 allow more wide range of checking that was not allowed when
4787 the code was in library. Now applications can do virtually any
4788 checks to the packet and return to the library the decision how
4789 the packet should be processed. Affected files are
4790 lib/silccore/silcpacket.[ch].
4792 Added silc_server_packet_decrypt_check to the server and
4793 silc_client_packet_decrypt_check to the client library.
4795 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4796 to send with specified source and destination information.
4798 * Channel message delivery between routers was broken after the
4799 channel key distribution was fixed earlier. The channel key
4800 was used be to distributed to other routers as well which is not
4801 allowed by the protocol. Now this is fixed and channel keys
4802 really are cell specific and the channel message delivery between
4803 routers comply with the protocol specification.
4805 * Fixed various commands in server to check also the global list
4806 for the channel entry and not just the local list. The affected
4807 file silcd/command.c.
4809 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4811 * Added assert()s to buffer formatting and unformatting routines
4812 to assert (if --enable-debug) when error occurs. Affected
4813 file: lib/silcutil/silcbuffmt.c.
4815 * Changed to auto-reconnect to check whether the remote host is
4816 router and register the re-connect timeout if it is. It used
4817 to check that whether we are normal server, but router must do
4818 auto-reconnect with another router as well. Affected file
4821 * Removed the [<key len>] option from CMODE command as the cipher
4822 name decides the key length, nowadays. See the defined ciphers
4823 from the protocol specification.
4825 * Added [<hmac>] option to the CMODE command to define the HMAC
4826 for the channel. Added SILC_CMODE_HMAC channel mode.
4828 * Added [<hmac>] option for the JOIN command so that user can
4829 select which HMAC is used to compute the MACs of the channel
4832 * Added Hmac field to the Channel Message Payload. The integrity
4833 of plaintext channel messages are now protected by computing
4834 MAC of the message and attaching the MAC to the payload. The
4835 MAC is encrypted. Now, it is clear that this causes some
4836 overhead to the size of the packet but rationale for this is that
4837 now the receiver can verify whether the channel message decrypted
4838 correctly and also when private keys are set for the channel the
4839 receiver can decrypt the packet with several keys and check from
4840 the MAC which key decrypted the message correctly.
4842 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4843 lib/silccrypt/silccipher.[ch].
4845 * Added silc_hash_len to return the digest length into the
4846 lib/silcrypt/silchash.[ch].
4848 * Rewrote parts of Silc Channel Payload interface in the
4849 lib/silccore/silcchannel.[ch]. The encode function now also
4850 encrypts the packet and parse function decrypts it.
4852 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4854 * Fixed a minor formatting bug in the SKE's key material processing.
4855 It actually might have processed the keys wrong way resulting
4858 * Redefined the mandatory HMAC algorithms and added new algorithms.
4859 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4860 and hmac-md5 truncated to 96 bits. The mandatory is now
4861 hmac-sha1-96. Rest are optional (including the one that used
4862 to be mandatory). Rationale for this is that the truncated HMAC
4863 length is sufficient from security point of view and can actually
4864 make the attack against the HMAC harder. Also, the truncated
4865 HMAC causes less overhead to the packets. See the RFC2104 for
4868 * Added new [hmac] configuration section. The SKE used to use
4869 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4870 is of course wrong. The official names that must be proposed in
4871 the SKE are the ones defined in the protocol specification
4872 (hmac-sha1-96 for example). The user can configure any hmac
4873 using any hash function configured in the [hash] section. At
4874 least, the mandatory must be configured.
4876 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4878 * Added HMAC list to the SKE proposal list. It has now both
4879 hash algorithm list and HMAC list. This makes the protocol
4880 incompatible with previous versions. The SKE now seems to work
4881 the way it is supposed to work, for the first time actually.
4883 * Defined plain Hash algorithms to the protocol specification.
4886 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4888 * Implemented support for key agreement packets into the server.
4889 Added functions silc_server_key_agreement and
4890 silc_server_send_key_agreement. Other than these functions,
4891 server has nothing to do with this packet.
4893 * Added support for private message key packets into the server.
4894 Added functions silc_server_private_message_key and
4895 silc_server_send_private_message_key.
4899 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4900 called in the protocol's final callback instead in the END
4901 protocol state. This makes a little more sense and in the same
4902 time in client we can use the same protocol routines for normal
4903 key exchange and to key agreement packet handling as well.
4905 * Added to both client's and server's KE protocol context the
4906 SilcSKEKeyMaterial pointer to save the key material. We will
4907 bring the key material to the protocol's final callback by doing
4908 this. The final callback must free the key material.
4910 * Added SKE's packet_send callback into client's KE protocol
4911 context so that the caller can choose what packet sending function
4912 is used. This way we can use different packet sending when
4913 doing normal SKE when doing key agreement packet handling (in
4914 the key agreement packet handling we do not want to encrypt
4917 * Implemented the responder side of the key agreement routines
4918 in the client. The client can now bind to specified port and
4919 accept incoming key negotiation. The key material is passed
4920 to the application after the protocol is over.
4922 * Implemented the processing of incoming Key Agreement packet
4923 in the client. Added function silc_client_key_agreement to
4926 * Implemented the intiator side of the key agreement routines
4927 in the client. The client can now initiate key agreement with
4928 another remote client. The key material is passed to the
4929 application after the protocol is over.
4931 * Created client_keyagr.c to include all the key agreement
4934 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4935 SILC_TASK_CALLBACK except that it is not static.
4937 * Created client_notify.c and moved the Notify packet handling
4938 from the client.[ch] into that file.
4940 * Created client_prvmsg.c and moved all private message and
4941 private message key routines from the client.[ch] into that file.
4943 * Create client_channel.c and moved all channel message and
4944 channel private key routines from the client.[ch] into that file.
4946 * Changed silc_client_get_client_by_id_resolve to resolve with
4947 WHOIS command instead of IDENTIFY command, in the file
4948 lib/silclient/idlist.c.
4950 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Implemented the SKE's responder side to the Client library.
4954 * When FAILURE is received to the protocol do not trust it
4955 blindly. Register a timeout to wait whether the remote closes
4956 the connection as it should do it, only after that process the
4957 actual failure. This was changed to both client and server.
4959 * Added client_internal.h to include some of the structures
4960 there instead of client.h in lib/silcclient/.
4962 * Added function silc_task_unregister_by_callback to unregister
4963 timeouts by the callback function.
4965 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4967 * Some "Incomplete WHOIS info" errors has been appearing on the
4968 log files. Took away the entry->userinfo check from WHOIS
4969 reply sending. The entry->userinfo is now " " if client did not
4970 provide one. I thought this was fixed earlier but something
4971 is wrong still. Let's see if the error still appears.
4973 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4975 * Fixed a minor bug in the login when the channel key is
4976 re-generated in the server. It used to generate the key in
4977 wrong order and thus caused problems in the channel traffic.
4979 * Fixed a minor bug in channel key distsribution after
4980 KICK command. The key was not sent to the router even though
4983 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4985 * Added silc_ske_process_key_material_data as generic routine
4986 to process any key material as the SILC protocol dictates. The
4987 function is used by the actual SKE library but can be used by
4988 applications as well. This relates to the private message keys
4989 and the channel private keys since they must be processed the
4990 same way the normal SILC session keys. The protocol dictates
4991 this. Affected files: lib/silcske/silcske.[ch].
4993 Added also silc_ske_free_key_material to free the
4994 SilcSKEKeyMaterial structure.
4996 * Defined silc_cipher_set_key function to set the key for
4997 cipher without using the object's method function. The affected
4998 files: lib/silccrypt/silccipher.[ch].
5000 * Implemented silc silc_client_add_private_message_key,
5001 silc_client_add_private_message_key_ske,
5002 silc_client_del_private_message_key,
5003 silc_client_list_private_message_keys and
5004 silc_client_free_private_message_keys functions in the
5007 Added functions silc_client_send_private_message_key to send
5008 the Private Message Key payload and silc_client_private_message_key
5009 to handle incoming Private Message Key payload.
5011 * Added Cipher field to the Private Message Key payload to set
5012 the cipher to be used. If ignored, the default cipher defined
5013 in the SILC protocol (aes-256-cbc) is used.
5015 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5017 * Removed lib/silcclient/ops.h file.
5019 Redefined parts of the SILC Client Library API. Created new
5020 file silcapi.h that deprecates the ops.h file and defines the
5021 published Client Library API. Defined also private message key
5022 API and channel private key API into the file.
5024 This is the file that the application must include from the
5025 SILC Client Library. Other files need not be included by
5026 the application anymore.
5028 * Added new key_agreement client operation callback and also
5029 defined the Key Agreement library API for the application.
5031 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5033 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5034 is used by clients to request key negotiation between another
5035 client in the SILC network. If the negotiation is started it
5036 is performed using the SKE protocol. The result of the
5037 negotiation, the secret key material, can be used for example
5038 as private message key.
5040 Implemented the Key Agreement payload into the files
5041 lib/silccore/silauth.[ch].
5043 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5045 * Redefined ciphers for the SILC protocol. Added some new ciphers
5046 and defined the key lengths for the algorithms. Changed the
5047 code accordingly. The default key length is now 256 bits.
5049 * Fixed SKE key distribution function silc_ske_process_key_material
5050 when the key length is more than 128 bits. The default key
5051 length in SILC is now 256 bits.
5053 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5054 to indicate unsupported algorithm.
5056 * Renamed rijndael.c to aes.c and all functions as well.
5058 * Fixed a long standing channel key setting bug in client library.
5059 Weird that it has never surfaced before.
5061 * Fixed bug in channel deletion. If the entire channel is removed
5062 then it must also delete the references of the channel entry
5063 from the client's channel list as the client's channel entry and
5064 the channel's client entry share same memory.
5066 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5068 * Implemented CONNECT and SHUTDOWN commands in the client.
5070 * Implemented CLOSE command to the client.
5072 * Added the function silc_idlist_find_server_by_name into the
5073 files silcd/idlist.[ch].
5075 Added the function silc_idlist_find_server_by_conn into the
5076 files silcd/idlist.[ch].
5078 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5080 * DIE command was renamed to SHUTDOWN. Updated the both code
5083 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5084 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5086 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5089 * Added function silc_server_create_connection function to create
5090 connection to remote router. My server implementation actually
5091 does not allow router to connect to normal server (it expects
5092 that normal server always initiates the connection to the router)
5093 so the CONNECT command is only good for connecting to another
5096 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5098 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5099 or some other client was kicked from the channel.
5101 Implemented the handling of the notify type to both client
5104 Implemented silc_server_send_notify_kicked to send the KICKED
5105 notify. It is used to send it to the server's primary router.
5107 * Implemented the KICK command into server and client.
5109 * Added `query' argument to the silc_idlist_get_client function
5110 to indicate whether to query the client from server or not if
5113 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5114 to indicate that the client is not channel founder.
5118 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5120 * Removed the rng context from SilcPacketContext structure and
5121 changed that the packet routine uses the Global RNG API.
5123 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5125 * Added support for quit message that client can "leave" on the
5126 channel when it quits the SILC. It is ditributed inside the
5127 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5129 Added silc_server_free_client_data that will take the
5130 signoff message as argument.
5132 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5134 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * Updated parts of the protocol specification to keep it up
5139 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5141 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5142 payloads in one packet.
5144 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5145 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5146 use now the new List flag.
5148 * Also deprecated the following packet types: REPLACE_ID,
5149 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5151 * Added list support for Notify packet in server.
5153 * Added silc_server_send_notify_channel_change to send the
5154 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5155 the silc_server_send_replace_id.
5157 * Added silc_server_send_notify_nick_change to send the
5158 NICK_CHANGE notify type. Deprecates the function
5159 silc_server_send_replace_id.
5161 * Added silc_server_send_notify_join to send the JOIN notify type.
5162 Deprecates the function silc_server_send_new_channel_user.
5164 * Added silc_server_send_notify_leave to send LEAVE notify type.
5165 Deprecates the function silc_server_send_remove_channel_user.
5167 * Added silc_server_send_notify_cmode and
5168 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5169 types. Deprecates the silc_server_send_set_mode function.
5171 * Added SERVER_SIGNOFF notify type to indicate that server has
5172 quit. This means that all clients on the channel from that
5173 server will drop. This can be also used when netsplit happens.
5175 Deprecated REMOVE_ID packet type since it is not needed anymore
5178 Added silc_server_send_notify_server_signoff to send the
5179 SERVER_SIGNOFF notify type. Deprecates the function
5180 silc_server_send_remove_id.
5182 Added also silc_server_send_notify_signoff to send the
5183 SIGNOFF notify type.
5185 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5186 SILC protocol from this day on. Changed the protocol
5187 specification as well.
5189 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5190 notify type. It is used between routers to notify about
5191 topic changes on a channel.
5193 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5196 * Partly updated the protocol specification to comply with the
5197 changes now made. It is still though a bit outdated.
5199 * The JOIN notify type now takes one extra argument <Channel ID>.
5200 The packet used to be destined to the channel but now the
5201 JOIN type may be sent as list thus it is impossible to
5202 destine it to any specific channel. By adding this argument
5203 it is again possible.
5205 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Added CREDITS file. The CHANGES and CREDITS file will appear
5208 in the distribution as well.
5210 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5212 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5213 types in the server's silcd/packet_receive.c.
5215 * Implemented CMODE and CUMODE to work in router environment.
5217 * Fixed minor encoding and decoding buglet from the
5218 lib/silccore/silcmode.c.
5220 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5223 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5225 * Changed all SilcConfigServer* and silc_config_server* to
5226 SilcServerConfig* and silc_server_config*, respectively.
5229 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5231 * Associated the ID (client or server ID) to the Authentication
5232 Payload to avoid any possibility of forging. Updated the
5233 protocol specification and the code accordingly.
5235 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5237 * The RSA key length is now save to the RsaKey context in the
5238 key generation process in lib/silccrypt/rsa.c. The key length
5239 is now used to figure out the maximum size of the block allowed
5240 to be encrypted/signed.
5242 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5243 is equivalent to the silc_mp_mp2bin but does not allocate any
5246 * Changed silc_mp_mp2bin API to take length argument. If it is
5247 non-zero then the buffer is allocated that large. If zero, then
5248 the size is approximated using silc_mp_sizeinbase, which however
5251 * Created Global RNG API which is global RNG that application can
5252 initialize. After initializing, any routine anywhere in the
5253 code (including library) can use RNG without allocating a new
5254 RNG object. This was done to allow this sort of use of the
5255 RNG in code that has no chance to allocate RNG object. All
5256 applications currently allocate this and many routines in the
5257 library use this. Affected file lib/silccrypt/silcrng.[ch].
5259 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5260 it to use the Global RNG API.
5262 * Defined Authentication Payload into protocol specification that
5263 is used during SILC session to authenticate entities. It is
5264 used for example by client to authenticate itself to the server
5265 to obtain server operator privileges.
5267 Implemented this payload into the lib/silccore/silcauth.[ch].
5268 Implemented also routines for public key based authentication
5269 as the new protocol specification dictates.
5271 Moved definitions of different authentication methods from
5272 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5274 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5275 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5276 silc_pkcs_verify_with_hash functions into the file
5277 lib/silccrypt/silcpkcs.[ch].
5279 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5281 * The client entry's userinfo pointer must be always valid.
5282 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5283 will fail since it requires the userinfo. Now, the userinfo
5284 is allocated as "" if actual userinfo does not exist. Actually,
5285 it must exist and it is totally Ok to drop client connections
5286 that does not announce the userinfo. However, we will make
5287 this workaround for now.
5289 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5290 to return the remote port by socket.
5292 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5294 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5295 SILC_SERVER_PENDING_EXEC and added an new macro
5296 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5297 data or when error occurs while processing the pending command.
5299 Added new argument `destructor' into silc_server_command_pending
5300 and to the SilcServerCommandPending object. This destructor is
5301 now called after calling the pending callback or if error occurs
5302 immediately. If error occurs the actual pending callback won't
5303 be called at all - only the destructor. The destructor may be
5304 NULL if destructor is not needed.
5306 All this applies for client library code as well. Similar
5307 changes were made there as well for the pending commands.
5309 In the client, the application must now allocate the
5310 SilcClientCommandContext with the silc_client_command_alloc
5313 * Added reference counter to the SilcServerCommandContext. Added
5314 function silc_server_command_alloc and silc_server_command_dup
5317 Same type of functions added to the client library for the same
5320 * Removed the cmd_ident from IDListData away since it is now
5321 global for all connections. It is the command identifier used
5322 in command sending and with pending commands. The affected file
5325 * Added reference counter to the SilcSocketConnection objecet to
5326 indicate the usage count of the object. The object won't be
5327 freed untill the reference counter hits zero. Currently only
5328 server uses this, and client ignores it. The client must be
5329 set to use this too later. The affected files are
5330 lib/silccore/silcsockconn.[ch]. Added also the function
5331 silc_socket_dup to increase the reference counter.
5333 This was mainly added because it is possible that the socket
5334 is removed underneath of pending command or other async
5335 operation. Now it won't be free'd and proper DISCONNECTING
5336 flags, etc. can be set to avoid sending data to connection that
5337 is not valid anymore.
5339 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5340 the connection. After that it sets SILC_SET_DISCONNECTED.
5341 It is, however, possible that the socket data is not still freed.
5342 The silc_server_packet_process now checks that data is not
5343 read or written to connection that is DISCONNECTED. The socket
5344 get's freed when the reference counter hits zero.
5346 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5348 * Changed the client operation API: channel_message operation's
5349 `sender' is now the client entry of the sender, not the nickname
5350 and the `channel' is the channel entry, not the channel name.
5352 In the private_message operation the `sender' is now also the
5353 client entry of the sender not the nickname.
5355 Affected file is lib/silcclient/ops.h and all applications
5356 using the client operations.
5358 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5360 * Moved the calling of ops->connect() from connect_to_server_final
5361 into receive_new_id functin since that is the point when the
5362 client is actually allowed to send traffic to network. The
5363 affected file is lib/silcclient/client.c.
5365 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5367 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5368 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5369 (if needs broadcasting) instead of broadcasting the packets one
5370 by one which would make a burst in the network traffic.
5372 * Added `broadcast' argument to the functions in silcd/server.[ch]
5373 silc_server_create_new_channel[_with_id] to indicate whether
5374 to send New Channel packet to primary router.
5376 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5378 * Added new function into the silcd/server.[ch] files:
5379 silc_server_create_new_channel_with_id to create new channel with
5380 already existing Channel ID.
5382 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5383 lib/silccore/silcpacket.h. This packet is used t send list of
5384 Set Mode payloads inside one packet. Server uses this to set
5385 the modes for the channels and clients on those channels, that it
5386 announced to the router when it connected to it. The protocol
5387 specification has been updated accordingly.
5389 * The silc_server_new_channel did not handle the packet coming
5390 from normal server as it normally does not send that. However,
5391 when it announces its channels it does send it. Implemented
5392 the support for that.
5394 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5395 into the file lib/silccore/id.h.
5397 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5399 * Fixed memory leaks in the functions silc_idlist_del_client,
5400 silc_idlist_del_channel and silc_idlist_del_server in the file
5401 silcd/idlist.c. All of those leaked like a sieve.
5403 * Fixed some small memory leaks in the client's function
5404 silc_client_notify_by_server.
5406 * Added functions into silcd/server.c: silc_server_announce_clients,
5407 silc_server_announce_channels and silc_server_announce_server.
5408 These functions are used by normal and router server to announce
5409 to its primary router about clients, channels and servers (when
5410 router) that we own. This is done after we've connected to the
5413 These functions effectively implements the following packet types:
5414 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5415 and SILC_PACKET_NEW_ID_LIST.
5417 * Added new functions into the silcd/packet_receive.[ch]:
5418 silc_server_new_id_list, silc_server_new_channel_list and
5419 silc_server_new_channel_user_list to handle the incoming
5420 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5422 * Added support of changing Channel ID in the function
5423 silc_server_replace_id. If the server that announces a channel
5424 to the router already exists in the router (with same name but
5425 with different Channel ID), router is responsible to send
5426 Replace ID packet to the server and force the server to change
5427 the Channel ID to the one router has.
5429 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5430 client that the Channel ID has been changed by the router. The
5431 normal server sends this to the client. Client must start using
5432 the new Channel ID as the channel's ID.
5434 Implemented handling of this new type into lib/silcclient/client.c
5435 into the function silc_client_notify_by_server.
5437 * Added new function silc_idlist_replace_channel_id into the files
5438 silcd/idlist.[ch] to replace the Channel ID.
5440 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5442 * Call silc_server_command_identify_check always when processing
5443 the IDENTIFY command in silcd/command.c
5445 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5447 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5448 send keepalive packets. The packet can be sent by clients,
5449 servers and routers.
5451 Added function silc_socket_set_heartbeat into the file
5452 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5453 If not set, the heartbeat is not performed. The actual
5454 heartbeat is implemented in the low level socket connection
5455 library. However, application is responsible of actually
5458 Added silc_server_send_heartbeat to send the actual heartbeat
5459 packet into silcd/packet_send.[ch]. Server now performs
5460 keepalive with all connections.
5462 * Added silc_task_get_first function into lib/silcutil/silctask.c
5463 to return the timeout task with shortest timeout. There was a bug
5464 in task unregistration that caused problems. TODO has been
5465 updated to include that task system must be rewritten.
5467 * The client library will now resolve the client information when
5468 receiving JOIN notify from server for client that we know but
5469 have incomplete information.
5471 * Rewrote parts of silc_server_remove_from_channels and
5472 silc_server_remove_from_one_channel as they did not remove the
5473 channel in some circumstances even though they should've.
5475 * Encryption problem encountered in server:
5477 The LEAVE command used to send the Channel Key packet to the
5478 router immediately after generating it. However, the code
5479 had earlier sent Remove Channel user packet but not immediately,
5480 ie. it was put to queue. The order of packets in the router
5481 was that Channel Key packet was first and Remove Channel User
5482 packet was second, even though they were encrypted in the
5483 reverse order. For this reason, MAC check failed. Now, this
5484 is fixed by not sending the Channel Key packet immediately but
5485 putting it to queue. However, this is more fundamental problem:
5486 packets that are in queue should actually not be encrypted
5487 because packets that are sent immediately gets encrypted
5488 actually with wrong IV (and thus MAC check fails). So, packets
5489 that are in queue should be encrypted when they are sent to
5490 the wire and not when they put to the queue.
5492 However, the problem is that the current system has not been
5493 designed to work that way. Instead, the packet is encrypted
5494 as soon as possible and left to the queue. The queue is then
5495 just purged into wire. There won't be any fixes for this
5496 any time soon. So, the current semantic for packet sending
5499 o If you send packet to remote host and do not force the send
5500 (the packet will be in queue) then all subsequent packets to the
5501 same remote host must also be put to the queue. Only after the
5502 queue has been purged is it safe again to force the packet
5505 o If you send all packets immediately then it safe to send
5506 any of subsequent packets through the queue, however, after
5507 the first packet is put to queue then any subsequent packets
5508 must also be put to the queue.
5510 Follow these rules and everything works fine.
5512 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5514 * Added new function silc_server_remove_clients_by_server to
5515 remove all client entries from ID list when the server connection
5516 is lost. In this case it is also important to invalidate all
5517 client entires as they hold the invalid server entry. This
5518 fixes fatal bug when server has lost connection and will reconnect
5521 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5523 * Made some sanity checks to silc_server_daemonise like to check
5524 whether the requested user and group actually exists.
5526 * Added sanity check to SKE's silc_ske_responder_finish to check
5527 that the public and private key actually is valid.
5529 * Invalidate the client's nickname when receiving Replace ID
5530 packet and the Client ID is being replaced. This means that the
5531 server will query the nickname if someone needs it (client)
5534 * Sort the ID Cache in client library when the ID Cache data
5535 has changed (needs sorting).
5537 * Do not allow for SILC client to create several connections to
5538 several servers. The client does not support windows right now
5539 and generating multiple connections causes weird behaviour.
5541 Irssi-silc client does support windows and can handle several
5542 connections without problems, see: www.irssi.org and SILC plugin.
5544 * Fixed some places where client was added to the IDList. The
5545 rule of thumb is following (in order to get everything right):
5546 If the client is directly connected local client then the
5547 `connection' argument must be set and `router' argument must be
5548 NULL to silc_idlist_add_client function. If the client is not
5549 directly connected client then the `router' argument must
5550 bet set and the `connection' argument must be NULL to the
5551 silc_idlist_add_client function.
5553 * The funtion silc_server_packet_send_local_channel actually did
5554 not check whether the client was locally connected or not. It
5555 does that now. Fixed a bug related to LEAVE command.
5557 * Fixed Remove Channel User payload parsing bug in server's
5558 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5560 * The server's silc_server_save_channel_key now checks also the
5561 global ID list for the channel as it might not be in the local
5562 list. Fixed a bug related to LEAVE command.
5564 * Is this the end of the [<unknown>] buglet that has been lurking
5565 around for a long time? A little for loop fix in server's
5566 silc_server_command_whois_parse that is used by both IDENTIFY
5567 and WHOIS command. At least, this was a clear bug and a cause
5568 of one type of [<unknown>] buglet.
5570 * WHOIS and IDENTIFY commands call the function
5571 silc_server_command_[whois/identify]_check function even if
5572 we are not router server.
5574 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5576 * Added --with-gmp configuration option. If set the GMP
5577 is always compiled in the SILC source tree. If not set then
5578 it is checked whether the system has the GMP3 installed. If
5579 it has then the GMP won't be compiled (the system's headers
5580 and library is used), if it doesn't have it then the GMP is
5581 compiled in the SILC source tree.
5583 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Changed RSA private exponent generation to what PKCS #1
5586 suggests. We try to find the smallest possible d by doing
5587 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5588 not security fix but optimization.
5590 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5592 * Added new config entry [Identity] to fork the server and run
5593 it as specific user and group. A patch from Bostik.
5595 * Imported Dotconf configuration library into lib/dotconf.
5596 This will be used to create the SILC configuration files later.
5597 It will appear in the distsribution after this commit.
5599 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5601 * A big code auditing weekend happening. Auditing code for
5602 obvious mistakes, bugs and errors. Also, removing any code
5605 Removed files for being obsolete:
5607 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5608 inline in the file lib/silcutil/silcbuffer.h)
5610 o lib/silcutil/silcbufutil.c (the header has inline versions)
5612 Changed code to fix possible error conditions:
5614 o The buffer formatting routines now check that the destination
5615 buffer really has enough space to add the data. This applies for
5616 both buffer formatting and unformatting
5617 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5618 unformatting was changed to accomodate following rules:
5619 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5620 sent to the function while XXX_*STRING will not allocate or copy
5621 the data into the buffer. Instead it sets the pointer from the
5622 buffer into the pointer sent as argument (XXX_*STRING used to
5623 require that the pointer must be allocated already). This change
5624 makes this whole thing a bit more consistent and more optimized
5625 (note that the data returned in the unformatting with XXX_*STRING
5626 must not be freed now). The routines return now -1 on error.
5628 o Tried to find all code that use buffer_format and buffer_unformat
5629 and added return value checking to prevent formatting and
5630 especially unformatting errors and possible subsequent fatal
5633 o Changed ske->x and ske->KEY to mallocated pointers in
5634 lib/silcske/silcske.h. Fixed possible data and memory leak.
5636 o Added return value checking to all *_parse* functions. Fixed
5637 many memory leaks as well.
5639 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5640 so that buffer overflows would not happen. All code now also
5641 checks the return value as it can fail.
5643 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5645 * Added reconnection support to server if the normal server looses
5646 its connection to the router (for example if router is rebooted).
5647 The server performs normal reconnection strategy implemented
5648 to the server. Affected file silcd/server.c.
5650 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5652 * Added new packet type SILC_PACKET_SET_MODE that is used to
5653 distribute the information about changed modes (for clients,
5654 channels and clients channel modes) to all routers in the
5655 network. Updated the protocol specification accordingly.
5657 Added functions into silcd/packet_send.c and
5658 silcd/packet_receive.c: silc_server_send_set_mode,
5659 silc_server_set_mode.
5661 Added new files silcmode.[ch] into lib/silccore that implements
5662 the encoding and decoding of Set Mode Payload. Added new type
5663 SilcSetModePayload. Moved the definitions of different modes
5664 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5666 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5668 * Oops, a little mistake in server's connection authentication
5669 protocol. The protocol is not ended with FAILURE but with
5670 SUCCESS if the authentication is Ok. :) Affected file is
5673 * Implemented NICK_CHANGE notify handling in server in the file
5674 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5675 the local clients on the channel. After the changing nickname
5676 in router environment snhould work and the [<unknown>] nickname
5677 should appear no more.
5679 The silc_server_replace_id function that receives the Replace ID
5680 payload now sends the NICK_CHANGE notify type also in the file
5681 silcd/packet_receive.c
5683 * Changed WHOIS and IDENTIFY command to support the maximum amount
5684 of arguments defined in protocol specs (3328 arguments). This
5685 fixed a bug that caused problems when there were more than three
5688 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5690 * Added extra parameter, command identifier, to the
5691 silc_client_send_command so that explicit command identifier
5694 Changed that ID list routines uses specific command identifier
5695 when sending WHOIS/IDENTIFY requests to the server so that they
5696 can be identified when the reply comes back.
5698 Affected files lib/silcclient/command.[ch],
5699 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5701 * Added `sender' argument to silc_server_packet_send_to_channel
5702 to indicaet the sender who originally sent the packet to us
5703 that we are now re-sending. Ignored if NULL. Affected file
5704 silcd/packet_send.[ch].
5706 * Added some server statistics support in silcd/server_internal.h
5707 SilcServerStatistics structure and around the server code. Also
5708 send some nice statistics information when client is connecting
5711 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5713 * Fixed channel ID decoding in server's JOIN command reply in
5714 silcd/command_reply.c
5716 * Fixed braodcasting of replace ID payload to not to send it if
5717 we are standalone server in silcd/packet_receive.c.
5719 * Fixed all channel message sending routines to not to send
5720 packets to clients that has router set, since they are routed
5721 separately in the same function earlier. Affects file
5722 silcd/packet_send.c and all channel packet sending functions.
5724 * In USERS reply, res_argv[i] are not allocated, the table
5725 is allocated. Thus changed that free the table, not its
5728 * In server's whois_check and identify_check if the client is
5729 locally connected do not send any WHOIS commands - they are not
5732 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5734 * Fixed some minor bugs in client when sending WHOIS command. The
5735 arguments was in wrong order.
5737 * Removed statis function add_to_channel from server in
5738 silcd/command.c that was previously used with the joining but
5741 * Tested USERS command in router environment successfully with two
5742 routers, two servers and two clients.
5744 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5746 * Reorganized the USERS command and command reply in client library
5747 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5748 When the command is given by user we register a pending command
5749 callback that will reprocess the command after the reply has been
5750 received from the server. When reprocessing the packet we then
5751 display the information. Thus, the USERS information is displayed
5752 now in the command callback instead of in the command reply
5753 callback. The processing of the command is same as previously
5754 when server has sent the command reply in the JOINing process.
5756 * Added to USERS command in silcd/command_reply.c to join the client,
5757 we didn't use to know about, to the channel after we've created
5758 a client entry for it. Also, for clienet we did know already still
5759 check whether it is on the channel or not and add it if not.
5761 * Removed silc_server_command_join_notify as the function and its
5764 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5766 * Changed the client's pending command handling to the same as the
5767 server's pending command handling. It is also now possible to
5768 execute command reply functions from other command reply
5769 function as the function callbacks for commands and command
5770 replies are one and same. The pending commands are not static
5771 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5772 in client connection context. Thus, pending commands are server
5773 connection specific as it is convenient.
5775 Changed the function silc_client_command_pending and
5776 silc_client_command_pending_del and added new function
5777 silc_client_command_pending_check. Removed the
5778 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5781 * Added cmd_ident, current command identifier, to the client
5782 connection context in lib/silcclient/client.h to keep track on
5783 command identifiers used in command sending. Client's command reply
5784 function handling now supports the mandatory command identifiers.
5786 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5787 funtions in client to fully support pending command callbacks.
5789 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5790 as one of the arguments to the application in the command reply
5793 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5794 before first releasing SILC but came back. Now it is removed again
5795 and should come back nomore. The FORWARDED flag was used only
5796 by the JOINing procedure by forwarding the command packet to router.
5797 Now, the JOINing procedure has been changed to more generic (due
5798 to various router environment issues) and FORWARDED is not needed
5799 anymore for anything. The protocol specification is yet to be
5802 Now, removed silc_server_packet_forward from server and the flag
5803 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5805 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5807 * Renamed NAMES command to USERS command. The NAMES was named that
5808 due to historical reasons. Now it is renamed. Also, rewrote
5809 parts of the USERS command. The nickname list is not sent anymore
5810 by the server. Only Client ID and mode lists are sent in the USERS
5811 command. Changed this also to the protocol specification.
5813 The client now resolves the names and stuff after it receives
5814 the USERS list from the server when joining to the channel.
5816 * WHOIS and IDENTIFY commands has been changed to support multiple
5817 Client ID's per command. One can now search for multiple users
5818 in the network by sending only one WHOIS or IDENTIFY command.
5819 Changed the code and the protocol specifications.
5821 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5822 uses silc_server_command_whois_parse to parse the request. */
5824 * If normal server, do not parse the WHOIS and IDENTIFY requests
5825 before sending it to the router. Saves some time.
5827 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5829 * Fixed JOIN command on client library. Wrong number of arguments
5830 used to crash the client.
5832 * Added silc_server_channel_has_global function to check whether
5833 channel has global users or not.
5835 * Added silc_server_channel_has_local function to check whether channel
5836 has locally connected clients on the channel.
5838 * The silc_server_remove_from_one_channel now checks whether the
5839 channel has global users or not after given client was removed from
5840 the channel. It also checks whether the channel has local clients
5841 on the channel anymore. If it does not have then the channel entry
5842 is removed as it is not needed anymore.
5844 * The silc_server_notify now checks on JOIN notify whether the joining
5845 client is one of locally connected or global. If it is global then
5846 the channel has now global users on the channel and that is marked
5847 to the channel entry. Also, it now saves the global client to
5848 global list who is joining and JOINs it to the channel. This is
5849 for normal server, that is.
5851 Changed silc_server_send_notify_on_channel,
5852 silc_server_packet_relay_to_channel and
5853 silc_server_packet_send_to_channel check if we are normal server
5854 and client has router set (ie. global client) do not send the
5855 message to that client, as it is already routed to our router.
5857 * Implemented LEAVE notify type handling in silc_server_notify
5860 * Tested LEAVE command in router environment successfully. Tested
5861 with two routers, two servers and two clients.
5865 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5867 * Implemented SIGNOFF notify type handling in silc_server_notify
5870 * silc_server_remove_id now removes the client entry from all channels
5871 it has joined and thusly sends SIGNOFF notify type.
5873 * Rewrote the NAMES list generation in server by removing two excess
5874 loops. The lists are created now inside one loop.
5876 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * silc_server_remove_channel_user checks now also global list
5879 for channel and client.
5881 * silc_server_new_channel_user checks now both local and global
5882 list for channel and client. Fixed a bug in client id decoding.
5883 Used to decode wrong buffer.
5885 * silc_server_channel_message checks now both local and global
5886 list for channel entry.
5888 * Tested channel joining (hence JOIN) in router environment
5889 successfully. Tested with two routers, two servers and two
5892 * Tested channel message sending in router environment successfully.
5894 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5896 * Added silc_server_save_channel_key into server.[ch] to save the
5897 received channel key in Channel Key payload processing. It is
5898 also used in JOIN command reply handling.
5900 Equivalent function silc_client_save_channel_key added into
5901 client.[ch] into client library.
5903 * Changed JOIN command reply to send information whether the channel
5904 was created or not (is existing already) and the channel key
5905 payload. Changed protocol specs accordingly.
5907 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5908 the request was sent by ID and not by nickname. Crashed on
5911 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5914 now correctly save the received data.
5916 * silc_server_free_sock_user_data now notifies routers in the
5917 network about entities leaving the network.
5919 At the same time implemented functions silc_server_remove_id
5920 and silc_server_send_remove_id to receive and send REMOVE_ID
5921 packets. The packet is used to notify routers in the network
5922 about leaving entities. The ID removed will become invalid in
5925 * Added function silc_idlist_del_server into server. Removes and
5926 free's server entry from ID list.
5928 * silc_server_private_message function now checks, if we are router,
5929 that the destination ID really is valid ID, naturally.
5931 * In router when NEW_ID packet is received (for new client) the
5932 hash of the Client ID is saved in the ID Cache but the
5933 client->nickname is set to NULL, instead of putting the hash
5936 IDENTIFY command now also checks that client->nickname must be
5937 valid. If it is not if will request the data from the server who
5938 owns the client. Added new function
5939 silc_server_command_identify_check.
5941 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5942 to set the command to already allocated Command Payload.
5944 * Tested private message sending in router environment with two
5945 routers, two servers and two clients. Fixed minor bugs and now
5948 * Fixed segfault from client's NAMES command. Used to crash if
5951 * Forwarded packets must not be routed even if it is not destined
5952 to the receiver. Changed server code comply with this.
5954 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5956 * Added `require_reverse_mapping' boolean value to ServerParams
5957 structure. If TRUE (not default) the server will require that
5958 the connecting host has fully qualified domain name.
5960 If the reverse mapping is not required and hostname could not be
5961 found the IP address is used as hostname.
5963 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5965 * Implemented version string checking to both client and server.
5966 The check is incomplete currently due to the abnormal version
5967 strings used in development version of SILC.
5969 * Changed all command functions in server to use the new
5972 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5974 * Changed char *data to unsigned char *data in ID Cache system to
5975 support binary data as ID Cache data. Changed code to support
5976 binary data in lib/silccore/idcache.c.
5978 * Renamed silc_server_packet_relay_command_reply to
5979 silc_server_command_reply as it is normal packet receiving
5980 function. Rewrote the function to accept command replys for
5981 servers and not only for clients.
5983 * Mark remote router always as registered server if we are connecting
5984 to it. Otherwise, commands sent by the router to us are ignored.
5986 * All ID List find routines now returns the ID Cache Entry pointer
5987 as well if requested.
5989 * WHOIS command works now in router environment, tested with two
5990 routers, two servers and two clients.
5992 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5993 in router environment (as it is almost equivalent to WHOIS) but
5994 hasn't been tested thoroughly. Added new functions:
5996 silc_server_command_identify_parse
5997 silc_server_command_identify_send_reply
5998 silc_server_command_identify_from_client
5999 silc_server_command_identify_from_server
6001 * Disabled route cache adding because adding two different ID's with
6002 same IP replaces the old cache entry thus giving wrong route.
6003 The entry->router->connection is always the fastest route anyway
6004 so route cache may not be needed. Of course, new routes maybe
6005 established after receiving the ID when the entry->router->connection
6006 might not be anymore the most optimal.
6008 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6010 * Add route cache for received ID for fast routing.
6012 * Added silc_server_packet_route to route received packet on router
6013 that is not destined to us.
6015 * Renamed silc_server_get_route to silc_server_route_get.
6017 * Added id_string and id_string_len fields into SilcServer to
6018 include encoded ServerID for fast comparing without excess
6019 encoding of the ID's.
6021 * Cleaned up WHOIS command on server side. Added following static
6024 silc_server_command_whois_parse
6025 silc_server_command_whois_check
6026 silc_server_command_whois_send_reply
6027 silc_server_command_whois_from_client
6028 silc_server_command_whois_from_server
6030 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6031 arguments in command replies. All command functions should be
6032 updated to use this macro.
6034 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6036 * Minor typo fixes on command reply handling on server.
6038 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6040 * Added silc_server_command_add_to_channel internal routine to add
6041 the client to the channel after router has created the channel and
6042 sent command reply to the server.
6044 * Added generic silc_server_send_command to send any command from
6047 * Use static buffer with ID rendering instead of duplicating data.
6049 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6051 * Fixed a channel user mode bug when joining to a channel server gave
6052 everybody channel founder rights, oops.
6054 * We mark ourselves as the router of the incoming server connection
6055 if we are router ourselves. This way we can check in some packet
6056 sending functions whether it is locally connected server. For
6057 incoming router connections we put NULL.
6059 * For router sending packets locally means now always sending the
6060 packet cell wide; to local clients and local servers. For normal
6061 server sending packet locally means sending it to only local
6064 * Fixed the JOIN command to really work in router environment. If the
6065 channel is created it is always created by the router. Router is
6066 also responsible of making the initial joining to the channel,
6067 sending JOIN notify to the sending server and distributing
6068 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6069 does not exist server doesn't do anything else but forward the
6070 command to the router which performs everything.
6072 * Added silc_server_send_channel_key function to send the Channel Key
6075 * Added silc_server_create_channel_key to create new channel key. The
6076 channel key is now re-generated everytime someone joins or leaves
6077 a channel, as protocol dictates. Note: channel->key_len is the
6080 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6082 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6083 packet_receive.[ch] to separate packet sending and receiving
6084 routines. The server.[ch] now includes everything else including
6085 actual packet processing (writing and reading data) and other
6088 Renamed silc_server_private_message_send_internal to
6089 silc_server_send_private_message. The routine is still though
6090 used only to relay private messages as server does not send
6091 private messages itself.
6093 Renamed silc_server_new_channel to silc_server_create_new_channel
6094 and added new function sicl_server_new_channel that handles the
6095 incoming New Channel packet. Added also new sending function
6096 silc_server_send_new_channel to send New Channel Payload.
6098 * Added new function silc_server_notify to process incoming notify
6099 packet to the server/router. Server may then relay the notify
6100 to clients if needed.
6102 * Added new function silc_server_new_channel_user to process incoming
6103 New Channel User packet. Router will redistribute the packet and
6104 send JOIN notify to its local clients and locally connected servers
6105 if needed. Normal server will send JOIN notify to its local client
6106 on same channel when received this packet. Added also corresponding
6107 sending function silc_server_send_new_channel_user to sent the
6110 * Added boolean route argument to send_notif_to_channel and
6111 packet_send_to_channel functions to attempt to route the packet
6112 if it is TRUE and send only locally if it is FALSE.
6114 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6116 * silc_server_replace_id now broadcasts the received replace ID
6117 packet if it is not broadcast packet already. The router must
6118 broadcast to inform other routers about changed ID.
6120 * Added backpointer to server's router into SilcServer context in
6121 silcd/server_internal.h.
6123 * Fixed silc_server_packet_broadcast to send correct broadcast
6126 * The channel key is now distributed to the local client as soon
6127 as it is received from the router (in router environment) so that
6128 no other packet may be sent for the channel until client has
6131 * silc_server_remove_channel_user now broadcasts the received
6132 Remove Channel User packet if it is not broadcast packet already.
6133 The router must broadcast to inform other routers about removed
6136 * Added users field into SilcPacketContext that is a reference count
6137 of the context. One can increase the reference count by calling
6138 silc_packet_context_dup which is now changed to just increase the
6139 reference count instead of duplicating the data. The reference
6140 count is decresed by calling silc_packet_context_free that will
6141 free the data after the reference count hits zero.
6143 For now on the packet context and everything allocated into it
6144 (including the raw packet from network) must be freed by calling
6145 the new silc_packet_context_free function. Added also new function
6146 silc_packet_context_alloc that must be used now to allocate the
6147 context. This also means that if a routine is asynchronous from
6148 silc_[client/server]_packet_parse_type the packet context must
6149 be duplicated by calling silc_packet_context_dup. Otherwise it
6150 gets free'd after silc_[client/server]_packet_parse_type returns.
6151 Also, one must remember that if packet is duplicated then its
6152 reference count must be decresed by calling the free function as
6153 many times as it was duplicated.
6155 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6156 from both client and server.
6158 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6160 * Made joining to a channel working in router environment.
6162 * Cleaned up JOIN command on server side and create function
6163 silc_server_command_join_channel internal routine to make the
6166 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6168 * Changed silc_command_pending list to SilcDList. Also, added
6169 `ident' field to SilcServerCommandPending structure to identify
6170 the reply and to call correct callback.
6172 Added silc_server_command_pending_check function to replace the
6173 corresnponding macro. The silc_command_pending list is not
6176 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6177 to set identifier to previously allocated Command Payload. It
6178 is used to set identifier for command when resending Command
6181 * Added silc_command_payload_encode_payload to encode Command
6182 Payload buffer from SilcCommandPayload structure.
6184 * Added silc_argument_payload_encode_payload to encode Argument
6185 payload buffer from SilcArgumentPayload structure.
6187 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6189 * Changed WHOIS command to support router connection on server side.
6190 The whois request is always sent to router unless the server is
6191 standalone server. After server has received the reply from the
6192 router will it send the reply to the client.
6194 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6195 broadcast received broadcast packet. The function is used only
6196 by router. The broadcast packet is always sent to the router's
6199 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6200 render given ID to printable string, for log files for example.
6202 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6204 * Made basic router to router connections working. At least they
6205 can now connect to each other but nothing really works the way
6206 they are supposed - yet.
6208 * Added new initiator token to RouterConnection configuration
6209 file in silcd/serverconfig.[ch]. It is used to tell whether we
6210 are the initiator to the remote router or whether we'll expect
6211 the other end to connect.
6213 * Moved registering of listener task to silc_server_init, hence
6214 the server starts listenning as soon as it is run, even if it
6215 does not have connections to other routers. Let's see how well
6218 * Changed default connection retry timeouts for more suitable in
6221 * Removed cipher and such arguments from silc_idlist_add_client
6222 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6223 Added new function silc_idlist_add_data to add the keys and stuff
6226 * Added SilcIDListData structure and added it to SilcClientEntry
6227 and SilcServerEntry as their first field in the structure. This
6228 way we can explicitly cast the ID entries to the SilcIDListData
6229 structure and get common data for the entries. In past, we had
6230 to first check what type of connection it is and then cast it to
6231 correct ID entry type. Now, we can directly cast the opaque
6232 pointer to the SilcIDListData (no matter what ID entry it actually
6233 is) and get the data needed.
6235 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6237 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6238 in some circumstances even if threre were timeout tasks, though not
6239 IO tasks, but tasks anyway. Now fixed.
6241 * Defined SilcServerConnection structure to hold connection specific
6242 stuff about directly connected servers and routers. The definition
6243 is currently in silcd/server_internal.h. I thought about having
6244 a bit more important role fro this struct but for now it is used
6245 only when connecting to other server (or router actually).
6247 * Added connecting retry support in server when connecting to
6248 router(s). The retry feature implement exponential backoff
6249 algorithm. Also, added SilcServerParams structure to hold default
6250 parameters for server. For now, it include these retry settings
6251 and are hard coded. After server is moded to be as Silc Server
6252 Library this structure will be more important.
6254 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6256 * Changed client librarys channel->clients table to SilcList and
6257 changed code accordingly.
6259 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6261 * Changed client's channel table to SilcList and changed code
6262 accordingly. Also changed SilcChannelClientEntry to include back-
6263 pointer to the channel so that client entry can use that structure
6264 as list as well and we have fast cross-reference to the channel.
6265 This change dramatically decreased the complexity of channel
6266 handling with client entry and vice versa (removed one extra
6267 loop when searching for channel entry from many functions).
6269 * Changed server->sim from table to SilcDList and changed code
6272 * NAMES command can now be used from user interface. It will show
6273 the user list on the channel, neatly.
6275 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6276 Code now saves realname of the user if it becomes available.
6278 * Renamed configure.in to configure.in.pre and made ./prepare
6279 script to automatically add correct version string to
6280 configure.in which it creates from configure.in.pre.
6282 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6284 * NAMES command reply now shows users mode with the nickname when
6287 * Moved silc_client_ch[u]mode[_char] functions from
6288 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6289 place sucks, they are utility functions and should be in some
6292 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6294 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6297 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6301 * Added TRQ (efficient deque and list library) into lib/trq. This is
6302 a very good list library that is currently used in the SILC. Defined
6303 SilcList API over the library because I didn't like the API very
6304 much. See lib/trq/silclist.h for the API and examples of how to
6305 use the API. Fixed various places in the code to use the new
6306 SilcList API. The SilcList is meant for lists that has a structure
6307 already defined as a list. It is not suitable to add just some
6308 context to the list (in TRQ, the context is the list actually).
6310 So, I defined SilcDList that can be used for the purpose where
6311 predefined list structure does not exit. This can be used as
6312 such list. Now some context just can be added to the SilcDList.
6313 Currently this list is not used in the SILC just yet, though there
6314 are a lot places where this can replace dynamically allocated
6315 tables and I will fix these places, later, to use SilcDList.
6316 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6317 and use TRQ internally).
6319 Also fixed some annoying warning messages that the original TRQ
6320 code generated. Also minor changes to TRQ's Makefile.in.
6322 * Added support for querying by Client ID to both WHOIS and
6323 IDENTIFY commands into server, as required by the protocol.
6325 * Removed method function pointers from SilcBuffer structure. They
6326 weren't used to anything and just increased the context size for
6327 no good reason. This change also made silc_buffer_alloc and
6328 silc_buffer_free functions inline functions.
6330 * Disabled command flooding detection support until it's fixed so
6331 that it accepts commands in but does not execute them more than once
6334 * Added silc_net_localhost(), to return local hostname, into
6335 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6336 that must be initialized before calling silc_client_init.
6338 * Added new function: silc_server_send_notify_on_channels to send
6339 notify messages to all channels client has joined. It is assured
6340 that the message is sent only once per client.
6342 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6343 lib/silcutil/silcutil.[ch] as silc_format function. The new
6344 function is generic and is used by server as well, not only by
6345 the logging routines.
6347 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6348 the provided version string was not acceptable. Added new function:
6349 silc_ske_check_version into lib/silcske/silcske.h. The function
6350 must be implemented by the application (client or server) and it
6351 does not reside in the SKE library. The function checks the version
6352 string remote end sent.
6354 * Added back pointers (to opaque context and to SilcSocketConnection)
6355 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6357 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6358 duplicate packet context structure.
6360 * Changed `notify' client operation to send same arguments as client
6361 receives from server except for ID's. ID's are mapped to correct
6362 ID entry and that is returned. Also, if channel entry is not sent
6363 by server but the notify is for channel the channel entry is sent
6364 to application (otherwise application doesn't know that it is for
6365 channel (library gets it from packet's Destination ID)).
6367 * Added silc_client_remove_from_channels into client library to
6368 remove a client from all channels it has joined to. Used when
6369 received SIGNOFF notify from server. Added also new function
6370 silc_client_replace_from_channels to replace old ID entry with
6371 new ID entry on all channels. Used when received NICK_CHANGE
6374 * Fixed ID Cache list handling in silc_idlist_get_client in
6375 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6376 to get (or query) client by ID.
6378 * Updated TODO list.
6380 * Added connection authentication status message defined by the
6381 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6382 support for these into the code in client and server side.
6384 * Added generic function silc_client_send_command to send any command
6385 with variable argument list. Application should use this function
6386 to send commands if the command functions provided by the library
6387 does not suite for the application's user interface needs.
6389 * Added new `failure' client operation. Application is notified about
6390 received failure packet if client is executing a protocol. In this
6391 case the protocol's execution has failed.
6393 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6394 is required by the protocol.
6396 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6397 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6400 * Added status flag to SilcSKE object to indicate realtime status
6401 of the SKE protocol.
6403 * Application receives now exactly same command reply arguments as
6404 the library receives from server. However, if ID is received the
6405 corresponding ID entry is returned to the application (eg. Client
6406 ID is mapped to correct SilcClientEntry entry and that is returned).
6407 Changed command_reply client operation due to this change.
6409 * Changed all ID's in commands and in command replys as ID Payloads.
6410 Change affected both client and server side codes.
6412 All ID's sent in SILC network (with execption of ID's in SILC
6413 Packet header) are sent in ID Payload to support variable length
6416 * Server now notifies nick changes and notifies all clients on
6417 the channels about the new nickname (about the new Client ID,
6420 * Implemented CMODE command to change channel modes. Supports all
6421 channel modes defined by the protocol specs except ban and invite
6422 lists. (Also, private channel key mode is supported but support for
6423 setting private channel key in client is missing, thus, this mode
6424 has no effect on client side (except that server requires that the
6425 client uses private channel key and normal channel traffic does not
6428 Also, invite mode works per se, but INVITE command does not work
6429 yet correctly, so you can set channel as invite only channel but
6430 inviting clients to the channel does not work (it is yet to be
6431 thought what's the best way to do it).
6433 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6434 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6435 Implemented CUMODE command to change user's mode on the channel.
6436 Supports all modes defined by the protocol specs.
6438 * Added NAMES command reply to return users modes on the channel.
6440 * Removed unnecessary and slow ciphers from lib/silccrypt.
6442 * Set SO_KEEPALIVE option to connection sockets by default.
6444 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6446 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6447 redefined the Notify Payload into protocol specs.
6449 * Added silc_id_payload_parse_id to get ID directly from raw
6452 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6454 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6455 accept searching by Client ID as well.
6457 * Added support for LEAVE and SIGNOFF notify types in client library.
6459 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6460 to parse ID Payload from raw data.
6462 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6464 * Added flags parameter into silc_ske_assemble_security_properties
6465 function in lib/silcske/silcske.[ch].
6467 * Changed notify client operation to fit better for notify messages
6468 sent by server. The notify payload received from server is now
6469 passed to the application (after parsing it to SilcNotifyPayload).
6470 It is application's responsibility to retrieve the arguments
6471 from the payload and show the message the way it wants. The message
6472 sent by server is implementation specific.
6474 * Changed public keys to comply with the protocol specification.
6475 Old public keys are not supported anymore and are not compatible.
6477 * Removed nickname from Channel Payload as the latest draft removed
6478 it. The client must resolve the nickname from the NAMES command
6479 reply received when it joined the channel.
6481 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6483 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6485 * Fixed some errors in protocol specification drafts.
6487 * Created lib/silccore/silcnotify.c to implement Notify Payload
6488 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6489 generic payloads described by protocol specifications. The file
6490 includes implementations for ID Payload and Argument Payload.
6492 * Changed Command Payload implementation to use the new Argument
6493 Payload. Changed command_xxxx_payload to command_payload_xxxx
6494 to comply with SILC coding conventions.
6496 * Added suppport for Argument Payload handling in Notify Payload
6497 implementation as protocol requires it. Added the new support
6498 into server and client lib as well.
6500 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6502 * Added support for multiple nicknames on same channel. [n] is
6503 added locally to the nickname if there are more than one same
6504 nicknames on the channel.
6506 * Server now sends all nicknames that matched WHOIS request.
6507 Client also shows the list received from server.
6509 * Added TOPIC command to client side. User can now set and show
6510 current topic on channel.
6512 * Added MOTD command to client and server. Also, server sends the
6513 motd when client connects to the server.
6515 * Changed version strings to comply ISO 8601.
6517 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6519 * Fixed protocol error handling in client library. It should now
6520 cope even if the SKE fails for some reason.
6522 * Made new protocol specification drafts for submitting to IETF.
6524 * Implemented TOPIC command to server in silcd/command.c.
6526 * Added two new notify types into lib/silccore/silcnotify.h:
6527 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6528 notify nickname change and topic setting/change on a channel.
6530 * API change of command_reply operation in client library. The
6531 application gets now the status type received from server as well.
6533 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6535 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6537 * Cras fixed and optimized the packet handling even further and
6538 it should work now. Minor change to the prototype of function
6539 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6541 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6543 * Added new function into lib/silcutil/silcschedule.[ch]:
6544 silc_schedule_with_fd to select() a specified fd. The function
6545 returns after timeout expires or data arrives or goes. The
6546 function is used by packet routines to wait that all data is
6547 received from network.
6549 * Fixed data reading from network in lib/silccore/silcpacket.c.
6550 The code now assures that all data is read from the fd and then
6551 continues packet processing. This was a bug fix since the code
6552 used to drop some data in some circumstances.
6554 * Added new function into lib/silcclient/client.[ch]:
6555 silc_client_start_key_exchange to start key exchange after
6556 connection has been established to server. The code internally
6557 now uses this funtion but its main purpose was to provide it
6558 for applications that perform their own connecting. After
6559 application has created a connection it merely calls this
6560 function to start the key exchange between client and server.
6561 The library takes care of everything else after that.
6563 Updated also lib/silcclient/README to explain the usage of
6566 * Do not send to application information that connection has
6567 been established. Application gets notified it by connect
6570 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6572 * Applied cras's patch to add silc_schedule_one function. The
6573 function runs scheduler once and returns.
6575 * Fixed the scheduler after cras messed it up. The timeout
6576 handling works now as it's supposed to work.
6578 * Added into lib/silccore/ silcnotify.h to include notify
6579 message types support. Changed silc_server_send_notify*
6580 functions, in server.[ch], to support those new notify types.
6581 Added the support for the notify types into client library,
6582 as well. Added new notify client operation into ops.h in
6585 * Changed silc_server_packet_send_to_channel to send normal
6586 packets instead of just channel message packets. The function
6587 is now used to send the notify packets to channels. It is not
6588 used to send channel message packets anymore, as server never
6591 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6592 va_arg()s as it seems to require it nowadays. I guess, if SILC
6593 is compiled with older va_arg() the new code should work anyway.
6595 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6597 * Splitted core library. Core library (lib/silccore) includes
6598 now only SILC protocol specific core (and common) components.
6599 Created new utility library (lib/silcutil) that includes more
6600 generic purpose stuff. The stuff for util library was taken
6601 from the old core library. This was minor and easy split.
6603 * Created SILC Client Library (lib/silcclient) that includes
6604 implementation of the SILC client without user interface. This
6605 was major move from silc/ directory. The code has been changed
6606 so that it is transparent towards the user interface. The
6607 silc/ directory includes now the same user interface as before
6608 and it uses the new client library. Read lib/silcclient/README.
6609 Basicly, the client library performs everything else related
6610 to SILC except user interface handling. Also, configuration
6611 files are considered to be part of user interface and library
6612 does not handle them.
6614 This change also changed a lot of structures, function naming etc.
6615 Most important change was that SilcClientWindow object was
6616 renamed to SilcClientConnection in the client library. Created
6617 also new file lib/silcclient/ops.h. Also added new files
6618 silc/local_command.[ch] and silc/client_ops.[ch].
6620 All these changes were made to make it easier for user interface
6621 designers to create what ever user interface for the SILC client
6624 It is also expected that the server will be moved to lib
6625 directory as well and SILC Server Library will be created;
6626 sometimes in the future.
6628 * Removed Local commands from lib/silccore/silccommand.h as
6629 they are application specific and new client library does not
6630 handle any of those anymore.
6632 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6633 old client implementation in silc/.
6635 * Added support for callback functions in SILC_LOG_* macros.
6636 Application can now set its own callbacks that will be called
6637 instead of using the default functions that will always print
6638 the debug messages to stderr (or stdout). Also, debugging can
6639 now be disabled by setting silc_debug to FALSE and re-enabled by
6640 setting it to TRUE. Note, that logging will still work even
6641 if debugging is disabled.
6643 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6644 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6645 silc_log_reset_debug_callbacks.
6647 * To enable debugging in silc client one must give now -d
6648 option on command line.
6650 * Changed silc_schedule_init to automatically allocate task queues
6651 if they are not allocated before calling it.
6653 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6655 * Added GMP 3.1 into math library.
6657 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6659 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6660 a channel in SILC network. The packet is used by servers and
6661 routers to notify other routers that user has left a channel.
6662 This little feature was missing until now. Added the feature
6663 to protocol specification as well.
6665 Added functions: silc_server_send_remove_channel_user and
6666 silc_server_remove_channel_user into server.[ch].
6668 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6669 lib/silccore/silcpacket.h. However, they are not implemented
6672 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6674 * Fixed joining to a channel and sending channel messages
6675 between server and router. The channel message sending should
6676 now work inside a cell.
6678 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * Fixed the private message sending between server and router.
6681 The private message sending should now work inside a cell.
6683 * Added silc_server_replace_id into server.[ch] to replace
6684 existing ID in the SILC network.
6686 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6687 and silc_idlist_replace_server_id into idlist.[ch] in server.
6689 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6691 * Fixed the server to server connections. Server can again now
6692 connect to router. Router to router connections probably does
6695 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6697 * Added dynamic protocol registering support. Now protocols can
6698 registered and unregistered on the fly. Patch by cras.
6700 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6702 * Added lib/contrib directory to hold routines that some platforms
6703 don't have but are needed by SILC.
6705 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6706 into lin/contrib to provide getopt() and getopt_long() for
6707 those who don't have it.
6709 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6711 * Added AWAY command to client. When away message is set and
6712 client receives a private message packet the client automatically
6713 replies to the sender with the away message.
6715 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6716 bug seemed to be the cause of recent problems when compiling
6719 * Added version detection support to SKE protocol specification
6720 and added the new changes to the SKE implementation as well.
6721 There were other minor changes in the SKE protocol as well.
6723 Many changes in lib/silcske/silcske.[ch] and in
6724 lib/silcske/payload.[ch].
6726 * Added ^U functionality, clear input line. Patch from cras.
6728 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6730 * Mainly small bugfixes on core library. Fixed some debugging
6731 logging and buffer overflow in silclog.c.
6733 * Updated config.sub and config.guess on the distribution tree.
6735 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6737 * Added command lagging support in server. Client may execute
6738 commands now only once in two seconds.
6740 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6742 * Optimized packet reception. MAC computation and checking is now
6743 also more optimized. A lot previously duplicated code is now
6744 used as generic by both client and server.
6746 * Fixed key pair generation in clientutil.c
6748 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6750 * Added into lib/silccore/silcbufutil.[ch] new function;
6751 silc_buffer_realloc.
6753 * Moved generic packet sending/encryption functions to
6754 lib/silccore/silcpacket.[ch] from client and server. Some
6755 rewriting of the functions.
6757 * Moved all generic packet reception/decryption functions to
6758 lib/silccore/silcpacket.[ch] from client and server. The
6759 packet processing is now much cleaner in both client and server.
6760 These were major changes in both client and server.
6762 * Created many common functions in server to do packet sending.
6763 Previously code were duplicated a lot, this has been removed
6766 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6768 * Rewrote major parts of the ID cache system. Don't know
6769 whether it is better now or not but at least the API is more
6772 * Major rewrite on ID cache stuff on client because of the ID
6773 cache API changes. Added idlist.c to client.
6775 * Also major rewrite on ID cache stuff on server as well.
6776 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6777 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6778 in hand, instead they are all put into the ID cache system now.
6779 All server_idlist_* routines uses ID cache now instead of
6780 traversing its own lists (those lists does not exist anymore).
6781 SilcIDList though still exists. Also, SilcXXXEntry's are
6784 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6786 * Finally made the SKE implementation compliant to the protocol
6787 specification. All mp integers are now binary encoded as
6788 opposed being HEX encoded.
6790 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6793 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6794 functions: silc_[encode/decode]_pem. Also added function
6795 silc_encode_pem_file to PEM encode with newlines ('\n') for
6798 * SILC public keys are now encoded either PEM or binary. Same
6799 option is for private keys as well. By default private keys
6800 are binary encoded and public keys PEM encoded. Silly HEX
6801 encoding were removed.
6803 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6804 function to create fingerprints.
6806 * Fixed a bug in SHA1; does not change the original data anymore.
6808 * Partly implemented INFO command on client and server side.
6809 Fixed CLEAR command. Changes to SERVER command; show current
6810 server(s) when giving command without arguments. Added
6811 VERSION command to client.
6813 * Added check to server that unregistered connections cannot
6814 execute commands (unless it is specificly allowed).
6816 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6818 * Fixed screen refresh.
6820 * Fixed channel joining bug from client. On some circumstances
6821 client tried to join to a channel it had already joined.
6823 * Added public key verification process into client's protocol.c.
6824 The client now verifies the public key from user and saves
6825 it into ~./silc/serverkeys/ directory.
6827 Added into: clientutil.[ch]: silc_client_verify_server_key.
6829 * Changed SKE protocol's silc_ske_initiator_finish function
6830 to accept callback function that verifies the received public
6831 key. Removed old silc_ske_verify_public_key function.
6833 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6835 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6836 silc_pkcs_private_key[_data]_set.
6838 * Made the password and public authentication more cleaner in
6839 server's protocol.c.
6841 * Removed historic and obsolete protocol `channel_auth' from
6842 both client and server.
6844 * Removed wrong way of sending command status messages from
6845 server to client in server's command.c. The old way violated
6846 protocol specification.
6848 Changes to silccore/silccommand.[ch]: removed
6849 silc_command_encode_status_payload -> not needed anymore,
6850 changed silc_command_encode_payload_va to accept extra
6851 argument on variable argument list. The argument type must
6852 now be provided to the function. Also, added new function:
6853 silc_command_encode_reply_payload_va which is same as
6854 normal command_encode_payload_va except command status type
6855 is provided as extra argument.
6857 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6859 * Added ~./silc directory handling. The directory includes the
6860 public and private keys for the client.
6862 Added silc_client_check_silc_dir, silc_client_create_identifier
6863 and silc_client_load_keys.
6865 * Implemented SILC protocol compliant public key. Added public
6866 and private key saving to and loading from files.
6868 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6869 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6870 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6871 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6872 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6874 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6875 silc_pkcs_load_[public/private]_key.
6877 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6879 * Added silc_server_get_route (route.[ch]) to get connection
6880 data for the fastest route for given ID.
6882 * Implemented INVITE command on client and server. The command
6883 were re-defined in the SILC Protocol Specification and the
6884 implementation now complies with the specification.
6886 * Implemented PING command on client and server.
6888 * Implemented NAMES command on client and server. The server side
6889 supports currently only normal server not router server yet.
6890 Some changes to NAMES definition in SILC protocol specification.
6892 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6894 * Implemented LEAVE command on client and server.
6896 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6897 again. This change was made to the protocol as well. Server
6898 should not violate the protocol specification anymore.
6900 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6902 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6903 was tested. SOCKS4 was not but should work anyway.
