1 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Do not constantly resize the window. A fix patch by cras.
4 Affected file irssi/src/fe-text/screen.c.
6 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
8 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
9 Affected file lib/silcutil/silcnet.c.
11 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
13 * Fixed a bug in hash table internal routine for traversing
14 the table with foreach callback. The current entry may
15 become invalid in the callback but it was referenced after
16 the callback returned.
18 Do not allow auto rehashing of hash table during the
19 silc_hash_table_foreach operation, for same reasons as it is
20 not allowed for SilcHashTableList. Affected files are
21 lib/silcutil/silchashtable.[ch].
23 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
25 * Defined DLLAPI into silcincludes.h and silcwin32.h for
26 Win32 DLL. extern's in header files are now declared with
29 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
31 * Fixed private message handling. It used some old code that
32 caused the client to crash. Affecte file is
33 lib/silcclient/client_prvmsg.c.
35 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
37 * Added function silc_client_add_channel,
38 silc_client_replace_channel_id, and removed functions
39 silc_client_new_channel_id and silc_idlist_get_channel_by_id
42 * Added cross reference of the joined channels to the
43 SilcClientEntry, and changed the SilcChannelEntry's
44 users list to SilcHashTable. The affected files are
45 lib/silcclient/idlist.[ch].
47 * Fixed a bug in hash table tarversing. While the hash table
48 is traversed with SilcHashTableList the table must not be
49 rehashed. It is now guaranteed that auto rehashable tables
50 are not rehashed while tarversing the list. Also defined that
51 silc_hash_table_rehash must not be called while tarversing
52 the table. Added function silc_hash_table_list_reset that must
53 be called after the tarversing is over. The affected files are
54 lib/silcutil/silchashtable.[ch].
56 * Changed all hash table traversing to call the new
57 silc_hash_table_list_reset in server and in client library.
59 * Added function silc_client_on_channel to return the
60 SilcChannelUser entry if the specified client entry is joined
61 on the specified channel. This is exported to application as
62 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
64 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
66 * Fixed founder regaining problem with JOIN command on normal
67 server. The notify for mode change must be sent always and
68 not only if !cmd->pending. Affected file silcd/command.c.
70 * Fixed the WHOWAS command's reply sending to support the
71 lists correctly. Affected file silcd/command.c.
73 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
75 * When sending JOIN command to router for processing the
76 sender's old command identifier was not saved back to the
77 sender's command context, fixed now. The affected file is
80 * Create the key in JOIN command of the router did not return
81 the channel key, added check for this. Affected file is
84 * Fixed a channel ID update bug in JOIN command reply. Do
85 not directly upgrade the ID but call the function
86 silc_idlist_replace_channel_id if the ID was changed.
87 Affected file silcd/command_reply.c.
89 * Fixed memory leaks from command calling if it would fail.
90 Affected file silcd/command.c.
92 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
94 * Applied patches from cras:
96 Memory leak fixes around libaries, irssi window resize fix,
97 new silclist.h and silcdlist.h, all extern inline changed to
100 * Removed dotconf from lib/dotconf, not needed anymore.
102 * Removed TRQ from lib/trq, not needed anymore.
104 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
105 with server connections. Later this will be configurable
106 in config file after new config file is done. Affected file
109 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
111 * Fixed a crash in server related to channel announcements.
112 Affected file silcd/server.c.
114 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
116 * Fixed memory leaks in silc_server_create_new_channel*
117 functions. Affected file silcd/server.c.
119 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
120 which ID was changed. This way the router will send the
121 user list for the channel again, and server won't be in
122 desync in some rare circumstances. Affected file is
123 silcd/packet_receive.c.
125 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
127 * Check for NULL socket pointer in the function
128 silc_server_packet_send_to_channel_real. Affected file
131 * Fixed the BAN notify handling to correctly remove ban
132 list. Affected file silcd/packet_receive.c.
134 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
136 * Fixed some header addition to Toolkit distribution in
137 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
139 * Added lib/silcclient/client_ops_example.h as an template
140 file for application programmers to quickly start using
141 the SilcClientOperation functions in their application.
142 Updated the lib/silcclient/README as well to tell about this
143 nice file made available.
145 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
147 * Call silc_server_remove_from_channels when removing client
148 entry when NO_SUCH_CLIENT_ID was received. Affected file
149 is silcd/command_reply.c.
151 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
153 * Added server & router operator statistics updating. Affected
154 file silcd/packet_receive.c and silcd/command.c.
156 * Fixed the SERVER_SIGNOFF notify handling on normal server
157 not to save the history information for clients. Same was
158 fixed earlier in remove_clients_by_server function, but not
159 here. Affected file silcd/packet_receive.c.
161 * Raised the default connection-retry count from 4 to 7 in
162 server. Affected file silcd/server.h.
164 * Cancel any possible reconnect timeouts when we start the
165 key exchange. Affected file silcd/server.c.
167 * Do not reconnect on connection failure when SCONNECT was
168 given. Affected files silcd/server.[ch].
170 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
172 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
174 * Fixed the NICK command to always give the unformatted
175 nickname to the one giving the NICK command. If unformatted
176 nickname is cached already it will be formatted and the
177 local entry will always get the unformatted nickname.
178 Affected file lib/silcclient/idlist.c.
180 * Fixed some double frees from client library commands.
181 Affected file is lib/silcclient/command.c.
183 * Fixed CUMODE command in server to assure that no one can
184 change founder's mode than the founder itself, there was a
185 little bug. Affected file silcd/command.c.
187 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
189 * Removed the SilcClientCommandDestructor from the client
190 libary, it is not needed anymore. Affected files are
191 lib/silcclient/silcapi.h, command[_reply].[ch],
192 client_notify, idlist.c.
194 * Fixed GETKEY command to first resolve client, and then
195 resolve the server only if the client was not found, instead
196 of resolving both at the same time. Affected file is
197 lib/silcclient/command.c.
199 * Added silc_client_start_key_exchange_cb and lookup the
200 remote hostname and IP address before starting the key
201 exchange with server. The affected file is
202 lib/silcclient/client.c.
204 * The server's public key is now saved using the IP address
205 of the server and not the servername for the filename.
206 The hostname public key filename is checked as an fall back
207 method if the IP address based filename is not found.
209 Fixed the GETKEY command to save the fetched server key
212 Print the remote server's hostname now when new key is
213 received during connection process. Affected file is
214 irssi/src/silc/core/client_ops.c.
216 * Return always our own public key to the client if it asks
217 for it with GETKEY command. Affected file silcd/command.c.
219 * Removed the use_auto_addr variable from default config
220 file since it was in wrong section. Affected file is
223 * Fixed TOPIC_CHANGE notification to not route it when it
224 was sent using silc_server_send_notify_to_channel function.
225 Affected file silcd/command.c.
227 * Fixed silc_server_send_notify_kicked to send the kicker's
228 Client ID also, it was missing. Affected files are
229 silcd/command.c, silcd/packet_send.[ch].
231 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
233 * Do not save client history information in SERVER_SIGNOFF.
234 Fixes the bug in normal server that it does not detect
235 the client becoming valid after the server becomes back
236 online. Affected file silcd/server_util.c.
238 * Added `sock_error' field into the SilcSocketConnection
239 context. When error occurs during socket operation (read
240 or write) the error is saved. Added also new function
241 silc_socket_get_error to return human readable socket error
242 message. Affected files are lib/silcutil/silcsockconn.[ch],
243 lib/silcutil/unix/silcunixsockconn.c, and
244 lib/silcutil/win32/silcwin32sockconn.c.
246 * The server now prints the socket error message in the
247 signoff for client. Affected file silcd/server.c.
249 * Fixed the `created' channel information sending from router
250 to server in JOIN command. Checks now whether the channel
251 really was created or not and set it according that.
253 Fixed the JOIN command to use the client entry's current
254 ID during the joining procedure instead of the one it sent
255 in the command (it is checked though), since it can change
256 between the packet processing and command processing, and
257 would just case unnecessary pain in the client end. Affected
258 file silcd/command.c.
260 * Fixed a channel key payload sending to use correct channel
261 ID when the server was forced to change the channel's ID by
262 router. Router sent the key payload with the old Channel ID.
263 Affected file silcd/packet_receive.c.
265 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
267 * Call silc_server_save_channel_key only if the key payload
268 was provided in the JOIN command's command reply. Affected
269 file silcd/command_reply.c.
271 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
273 * Fixed silc_mp_sizeinbase to return the value correctly with
274 MPI. Affected file lib/silcmath/mp_mpi.c.
276 * Fixed the stop_server signal to correctly stop the scheduler
277 and gracefully stop the server when SIGTERM or SIGINT signals
278 are received. Affected file silcd/silcd.c.
280 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
282 * Simple handling of TERM and HUP signals. Also added some log
283 flushing call around. Affected file is
286 * Fixed small bugs in silclog.c. Now buffering output will take
287 effect after 10 seconds since startup: This will ensure that
288 no important startup messages are lost. Also output redirection
289 will preserve original format ([Date] [Type] message).
290 Affected file is lib/silcutil/silclog.c.
292 * Added two options to the config file, in the logging section:
293 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
294 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
296 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
298 * Do not print the warning about log files not being initialized
299 more than once to avoid excess logging. Affected file is
300 lib/silcutil/silclog.c.
302 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
303 the SIM copying in make install in Makefile.am.pre.
305 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
307 * Rewritten silclog APIs. Globally interesting changes follows:
308 silc_log_set_files() changed to silc_log_set_file().
309 silc_log_set_callbacks() changed to silc_log_set_callback().
310 ROBOdoc documented silclog header file.
311 SilcLogCb now returns bool to wether inihibit the default
312 handler or not (to keep the old behaviour return always TRUE).
313 The new APIs should also fix the problem of the
314 silcd_error.log file that was written in the current directory.
317 Log files streams will remain opened after silc_log_set_file()
318 call, means less CPU usage notably on high traffic servers.
319 File streams are now full buffered, and flushed to the disk
320 every 5 minutes, lesses HD activity and CPU usage.
321 Messages can be redirected, allowing admins to configure
322 one single logfile for all server messages.
323 the silc_log_quick global variable to activate fast-logging.
324 Affected files lib/silcutil/silclog.[ch]
326 * Changed some code to conform new silclog APIs. Affected
327 files are doc/example_silcd.conf.in, silcd/server.c
328 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
331 * Fixed a memory leak that could occur in some situations.
332 Affected file silcd/serverconfig.c.
334 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
336 * Added the silc_client_del_client to remove the client from
337 all channels as well. Affected file lib/silcclient/idlist.c.
339 * Fixed the client library to correctly remove the client
340 from all channels when the client entry is being destroyed.
341 Affected file lib/silcclient/client_notify.c, command.c.
343 * Added auto-nicking support to the client library. If the
344 applicatio now sets client->nickname it will be sent to the
345 server after connecting by the library. This way for example
346 SILCNICK (or IRCNICK) environment variables will have effect
347 and always change the nickname automatically to whatever
348 it is wanted. Affected file lib/silcclient/client.[ch].
350 * Renamed silc_server_command_bad_chars to the
351 silc_server_name_bad_chars and moved it to the
352 silcd/server_util.[ch]. Added also new function
353 silc_server_name_modify_bad to return nickname that
354 includes bad characters as new nickname without those
355 bad characters. This check and modify is now used in
356 silc_server_new_client when the username is initially set
357 as nickname, so it must be checked to be valid nickname.
358 Affected file silcd/packet_receive.c.
360 * The nickname length is now taken from the packet for real
361 and not trusted to strlen() since it clearly can return
362 wrong length for nickname including bad characters. This
363 also applies to channel names. Affected file silcd/command.c.
365 * Removed the lib/silcsilm/modules directory. Modules are now
366 compiled into the lib/silcsim. Fixed the copying of the
367 modules to follow symbolic links in Makefile.am.pre.
369 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
371 * Fixed silc_string_regexify list creation. Fixes bugs with
372 BAN and INVITE commands in server. The affected file is
373 lib/silcutil/unix/silcunixutil.c.
375 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
377 * Removed the command destructor entirely from the server's
378 command and command reply routines. It is not needed, and
379 its usage was buggy and caused crashes. Affected files are
380 silcd/command[_reply].[ch].
382 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
384 * Cancel protocol and NULL sock->protocol if timeout
385 occurred during protocol. Affected file silcd/server.c.
387 * Cancel protocol timeouts always before calling the final
388 callback, to assure that after final callback is called
389 no other state will be called for the protocol anymore.
390 Affected file silcd/protocol.c.
392 * Print error log if incoming connection configuration could
393 not be found. Affected file silcd/server.c.
395 * Fixed JOIN command to correctly save the founder mode
396 to the client on normal SILC server, when the channel
397 was created by the router. Affected file silcd/command.c.
399 * Fixed LIST command (hopefully) to send correct reply
400 packets. Affected file silcd/command.c.
402 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
404 * The silc_packet_receive_process now returns FALSE if the
405 read data was invalid packet, and TRUE if it was ok.
407 The server now checks that if unauthenticated connection
408 sends data and its processing fails the server will close
409 the connection since it could be a malicious flooder.
411 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
413 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
415 * Make sure the warning about error opening a log file is
416 printed only once and not everytime it fails (produces
417 too much useless log). Affected file lib/silcutil/silclog.c.
419 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
421 * Made the silc_server_daemonise() function more readable.
422 Affected file silcd/server.c.
424 * Pid file is now optional, the user may comment it out from
425 the config file. Removed define SILC_SERVER_PID_FILE, we
426 don't need a default any longer. Affected file
427 configure.in.pre, lib/Makefile.am.pre.
429 * Make some use of the pid file. The server now dies at startup
430 if it detects a valid pid file on his path. The server would
431 die anyway in this circumstance, because of the bind() failure.
432 Affected file silcd/silcd.c.
434 * No longer compiling lib/dotconf.
436 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
438 * Fixed JOIN command parsing not to crash. Affected file
439 lib/silcclient/command.c.
441 * Fied the NICK_CHANGE notify to add the new client entry
442 even it is resolved. This removes an <[unknown]> nick
443 thingy bug in the client. Affected file is
444 lib/silcclient/client_notify.c.
446 * Do not try to allocate 0 bytes (efence does not like it)
447 in lib/silccore/silccomand.c when encoding payload.
449 * Do not take IRCNICK as nickname in Irssi SILC client since
450 it is not possible to set nickname before hand connecting
451 the server (TODO has an entry about adding auto-nicking
454 * Changed the silc_server_command_pending to check whether
455 there already exists an pending entry with the specified
456 command, command identifier and pending callback. This is
457 to fix IDENTIFY and WHOIS related crashes that may register
458 multiple pending commands with same identifier. Affected
459 file silcd/command.c.
461 * Fixed the server to reconnect to the router even if it
462 was already reconnecting and EOF was received. This to
463 fix a possibility that the server wouldn't ever try to
464 auto-reconnect to the router. Affected file silcd/server.c.
466 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
468 * Fixed the server's password authentication to use the
469 length of the locally saved password, and not the one
470 sent in the packet. Affected file silcd/protocol.c.
472 * Fixed same password authentication problem in the
473 Authentication Payload handling routines in
474 lib/silccore/silcauth.c.
476 * Yet another password authentication problem fixed with
477 channel password handling in silcd/command.c.
479 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
481 * If first character of string in silc_parse_userfqdn is '@'
482 then do not parse it. Affected file is
483 lib/silcutil/silcutil.c.
485 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
487 * Fixed minor bug in IDENTIFY command reply sending, which
488 caused various weird problems during JOIN when it was
489 resolving names for users. Affected file silcd/command.c.
491 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
493 * Fixed the IDENTIFY command reply sending to chech better valid
494 clients. It was possible to send incomplete list of replies.
495 Affected file silcd/command.c.
497 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
499 * Added silc_client_command[s]_[un]register functions now to
500 dynamically register the commands in client library. Removed
501 the static table of commands. This allows the client library
502 to call commands without causing the application to know about
503 what commands library has called.
505 Removed the INFO command reply kludge to detect when the command
506 was called by library. Now library use its own command reply
507 function for INFO command.
509 Added function silc_client_command_call to call a command.
510 Application can use it to call command, not access the structure
513 Now all commands that are sent by the client library (not
514 explicitly sent by application) use own command reply functions.
516 Affected files around lib/silcclient/ and in
517 irssi/src/silc/core/.
519 * Fixed the WHOIS command reply sending to chech better valid
520 clients. It was possible to send incomplete list of replies.
522 Fixed the WHOIS and IDENTIFY to send the request to router
523 if normal server did not do it and did not find any results.
525 Affected file silcd/command.c.
527 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
529 * Moved the internal data from SilcClient context into its
530 own file, not accesible to application. Affected files
531 lib/silcclient/client.h and lib/silcclient/client_internal.h,
532 and other files in client library.
534 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
536 * Added doc/examples installation target in Makefile.am.pre.
539 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
541 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
542 commands the found client entry will be removed from the
543 cache, after notifying application about the error. Affected
544 file lib/silcclient/command_reply.c.
546 * Changed the /MSG to check for exact nickname user gave, and
547 not let `nick' match `nick@host' if it is only one found. Now,
548 user must type the exact nickname (like nick@host2) even if
549 there are no more than one same nicks found. This is to avoid
550 a possibility of sending nickname to wrong nickname since
551 `nick' could match `nick@host'. Affected file is
552 irssi/src/core/silc-servers.c.
554 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
556 * Do not print "you are now server operator" or similar when
557 giving /away command. Affected files are
558 irssi/src/silc/core/client_ops.c, silc-servers.h.
560 * Made the silc_server_command_pending_error_check to send
561 the same command reply payload it received back to the
562 original sender of the command. This way all arguments
563 that was received by the server will be received by the
564 client too. Affected file silcd/command.c.
566 * Added the silc_idcache_add to return the created cache entry
567 to a pointer. Affected file lib/silccore/silcidcache.[ch].
569 * Add global clients to expire if they are not on any channel.
570 This is because normal server will never know if they signoff
571 if they are not on any channel. The cache expiry will take
572 case of these entries. This is done by normal servers only.
573 The affected files are silcd/command_reply.c,
574 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
576 * If server receives invalid ID notification for WHOIS or
577 IDENTIFY and the ID exists in the lists, it is removed.
578 Affected file silcd/command_reply.c.
580 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
581 in client then client entry that it matches is searched and
582 the nickname is printed on the screen for user. Affected
583 file irssi/src/silc/core/client_ops.c.
585 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
587 * Use cache entry expire time in the LIST command reply to
588 purge old entries from the cache after the LIST command
589 reply has been received. This way we don't have non-existent
590 entries in the cache for too long. Affected file is
591 silcd/command_reply.c.
593 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
595 * If we are normal server, and we've not resolved client info
596 in WHOIS or IDENTIFY from router, and it is global client,
597 we'll check whether it is on some channel. If it is not
598 then we cannot be sure about its validity and will resolve it
599 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
600 file silcd/command.c.
602 * Search channel by name (if possible) rather than by ID
603 in IDENTIFY command's command reply. Affected file is
604 silcd/command_reply.c.
606 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
608 * Distribute to the channel passphrase in CMODE_CHANGE notify.
609 Updated specs and implemented it. Affected file silcd/command.c,
610 silcd/packet_send.c and silcd/packet_receive.c.
612 * Implemented the <founder auth> payload handling in the JOIN
613 command. If provided all conditions for channel joining
614 except requirement to provide correct passphrase can be
615 overrided by the channel founder. Updated the protocol specs.
616 Affected file silcd/command.c.
618 Added support for founder auth in JOIN command in client
619 library. Fixed the parsing of the JOIN command now to support
620 all options as they should be. The affected file is
621 lib/silcclient/command.c.
623 * Optimized the WHOIS and IDENTIFY commands to send the request
624 to router only if it includes nicknames or other names. If
625 they include only IDs then check the local cache first before
626 routing. Affected file is silcd/command.c.
628 * Added channels topic announcements. Affected file is
629 silcd/packet_receive.c and silcd/server.c.
631 * Fixed the silc_server_send_notify_topic_set to really destine
632 the packet to channel. Affected file silcd/packet_send.c.
634 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
635 library. Affected file lib/silcclient/client_notify.c.
637 * Added UMODE announcements. Affected file silcd/server.c.
639 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
641 * Memory leak fixes in:
643 lib/silcutil/silcsockconn.c
644 lib/silcske/silcske.c
647 lib/silccrypt/silcpkcs.c
648 lib/silccore/silccommand.c
649 lib/silccore/silcidcache.c
654 * ROBOdoc documented the lib/silcske/groups.h file and a
655 bit changed the interface for better.
657 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
659 * Update the client entry context in the ID cache after
660 nick change. Affected file lib/silcclient/command.c.
661 Fixes the CUMODE command when regaining founder privileges,
662 and a little WHOIS problem.
664 * Fixed silc_net_gethostbyname to correctly call the
665 inet_ntop. Affected file lib/silcutil/silcnet.c.
667 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
669 * Added IPv6 support checking to the configure.in.pre, added
670 also --enable-ipv6 option to override the check. Affected
671 file configure.in.pre.
673 * The silc_thread_create now calls the start function
674 directly if threads support is not compiled in. Removes
675 ugly #ifdef's from generic code. Affected files are
676 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
678 * Added silc_net_gethostby[name/addr]_async to asynchronously
679 resolve. Affected files are lib/silcutil/silcnet.[ch].
681 * Added support for rendering IPv6 based server, client and
682 channel IDs. Affected file lib/silcutil/silcutil.c.
684 * Added support for creating IPv6 based server IDs. Affected
685 file is silcd/serverid.c.
687 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
689 * Added silc_net_gethostby[addr/name] into the
690 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
691 routines. Added silc_net_is_ip[4/6]. Affected file is
692 lib/silcutil/unix/silcunixnet.c. All routines that take
693 address as argument now supports both IPv4 and IPv6 addresses.
695 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
697 * Fixed LIST command reply sending in server. Affected file
700 * Server now sends the kicker's client ID in the KICK notify
701 to the kicked client. Affected file silcd/command.c.
703 * The client library now parses the kickers client ID and
704 UI displays it. Affected files lib/silcclient/client_notify.c
705 and irssi/src/silc/core/silc-channels.c, module-formats.c.
707 * Made all payload parsing function prototypes consistent.
708 They all take now const unsigned char * and uint32 pair as
709 the payload data instead of SilcBuffer. Changes all around
710 the source tree. Other unsigned char* -> const unsigned char*
711 changes around the tree as well.
713 * Optimized SFTP client and server packet sending not to
714 allocate new buffer for each packet but to recycle the
715 first allocated buffer. Affected files are
716 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
718 * Optimized the SFTP client to use SilcList instead of
719 SilcDList for requests, because it is faster. Affected file
720 is lib/silcsftp/sftp_client.c.
722 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
723 into lib/silccore/silcid.[ch].
725 Renamed silcpayload.[ch] into silcargument.[ch].
727 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
729 * If client entry is deleted with active key agreement
730 session, abort the session.
732 The silc_client_abort_key_agreement now calls the completion
733 callback with new SILC_KEY_AGREEMENT_ABORTED status.
735 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
738 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
740 * Don't use __restrict in older GCC's. Affected file is
741 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
743 * silc_net_localhost now attempts to reverse lookup the
744 IP/hostname. Affected file lib/silcutil/silcnet.c.
746 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
747 command. It can be used to gain founder privileges at
748 the same time when joining the channel.
750 Defined that the SILC_NOTIFY_TYPE_KICKED send the
751 kicker's client ID as well. Updated protocol specs.
753 Defined that the server must send SILC_COMMAND_IDENTIFY
754 command reply with error status to client who sent
755 private message with invalid client ID.
757 Updated the protocol specification.
759 * Added silc_server_send_command_reply to send any
760 command reply. Affected file silcd/packet_send.[ch].
762 * Added silc_id_payload_encode_data to encode ID payload
763 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
765 * The server now send IDENTIFY command reply with error
766 status if client ID in private message is invalid. Affected
767 file silcd/packet_receive.c.
769 * Save the server key file with server's IP address in
770 the filename instead of hostname. The affected file is
771 irssi/src/silc/core/client_ops.c.
773 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
775 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
778 * Added libtool support for compiling shared objects in
779 lib/silcsim. Affected file configure.in.pre and
780 lib/silcsim/Makefile.am. Original patch by cras.
782 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
784 * Pid file configuration, and server's config file fixes
785 patch by toma. Updated CREDITS file.
787 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
789 * Fixed silc_client_channel_message to not try to decrypt
790 the message twice if it resolved the destination client
791 information. This could cause of dropping one channel
792 message. Affected file lib/silcclient/client_channel.c.
794 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
796 * Added silc_client_run_one into lib/silcclient/silcapi.h and
797 lib/silcclient/client.c. This function is used when the SILC
798 Client is run under some other scheduler, or event loop or
799 main loop. On GUI applications, for example this may be
800 desired to used to run the client under the GUI application's
801 main loop. Typically the GUI application would register an
802 idle task that calls this function multiple times in a second
803 to quickly process the SILC specific data.
805 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
807 * Fixed silc_server_drop() for dropping the supplementary
808 groups as well, this could cause a security hole on some
811 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
813 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
816 * Write PID file after dropping privileges. Added -F option
817 to run server on foreground. A patch by debolaz.
818 Affected files silcd/server.c, silcd/silcd.c.
820 * Fixed MOTD to return the MOTD file server name. Affected
821 file silcd/command.c.
823 * Added INFO command reply handling to the Irssi SILC Client.
824 Affected file irssi/src/silc/core/client_ops.c.
826 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
828 * Fixed the silc_idcache_list_* routines to really support
829 the dynamic list. Fixes a crash. Affected file is
830 lib/silccore/silcidcache.c.
832 * Fixed the LIST command reply to really call LIST command's
833 pending callbacks. Affected file silcd/command_reply.c.
835 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
837 * Update conn->local_entry->nickname after giving NICK
838 command. Affected file lib/silcclient/command.c.
840 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
842 * Added the [pid] option to the silcd configuration file
844 Affected files: serverconfig.[ch] and silcd.c
846 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
848 * Save fingerprint in WHOIS command reply in server.
849 Affected file silcd/command_reply.c.
851 * Fixed NICK commands pending callback registration.
852 Affected file lib/silcclient/command.c.
854 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
856 * Use ++server->cmd_ident when sending commands in server,
857 instead of random number. Affected file silcd/command.c.
859 * Fixed GETKEY command reply to call actually GETKEY pending
860 command callbacks. Affected file silcd/command_reply.c.
862 * A bit stricter check for nicknames. Check for same nickname
863 in NICK command also. Affected file silcd/command.c.
865 * Do not call INFO command everytime client ID changes, only
866 during first connecting. Affected file lib/silcclient/client.c.
868 * Set the new nickname only after successful command reply for
869 NICK command is returned by server. Affected file
870 lib/silcclient/command.c.
872 * Remove nicknames from nicklist during server_signoff notify.
873 Should fix /NAMES bit more. The affected file is
874 irssi/src/silc/core/silc-channels.c.
876 * Added `fingerprint' field to the SilcIDListData in the
877 silcd/idlist.h to hold the fingerprint of the client's
880 Send the fingerprint of the client's public key in WHOIS
883 Affected files silcd/command.c, and silcd/idlist.[ch].
885 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
886 create fingerprint from given data.
888 * Show the fingerprint of the client's public key in WHOIS.
889 Affected files irssi/src/module-formats.[ch] and
890 irssi/src/silc/core/client_ops.c.
892 * Format the multiple same nicknames also during JOIN and
893 NICK_CHANGE notifys. Affected file is
894 lib/silcclient/client_notify.c.
896 * Do not print error on screen for invalid private message
897 payload since it can come if someone is sending private
898 messages with wrong key. Affected file
899 lib/silccore/silcprivate.c.
901 * Fixed multiple concurrent /PING crash. Affected file
902 lib/silcclient/command.c.
904 * Changed the wrong ID encoding. All IP addresses must be
905 in MSB first order in encoded format. They were encoded
906 wrong and was in LSB format. Affected files are
907 silcd/serverid.c, lib/silcutil/silcutil.c.
909 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
911 * Call the `connect' client operation through the scheduler
912 in case of error. Affected file lib/silcclient/client.c.
914 * Call the `failure' client operation even if the error
915 occurred locally during a protocol. Affected file is
916 lib/silcclient/protocol.c.
918 * Added support of sending LIST command to router from normal
919 server. This way normal server can get list of all channels
920 in the network too. Fixed the channel list sending in the
921 server too. Affected files are silcd/command.c, and
922 silcd/command_reply.[ch].
924 * Added silc_server_update_channels_by_server and
925 silc_server_remove_channels_by_server. They are used during
926 disconnection of primary router and in backup router protocol.
927 Affected file silcd/server_util.[ch], silcd/server.c and
928 silcd/server_backup.c.
930 * Fixed channel adding to global list in IDENTIFY command
931 reply in server. Affected file silcd/command_reply.c.
933 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
935 * If the incoming packet type is REKEY or REKEY_DONE process
936 that packet always synchronously. Fixes yet another MAC
937 failed error on slow (dialup) connections. Affected file
938 lib/silcclient/client.c and silcd/server.c.
940 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
942 * Call check_version SKE callback for initiator too. Affected
943 file lib/silcske/silcske.c.
945 * Implemented fix for security hole found in the SKE that was
946 fixed in the specification few days back; the initiator's
947 public key is now added to the HASH value computation.
948 Added backwards support for the old way of doing it too, for
949 old clients and old servers. Affected file is
950 lib/silcske/silcske.c.
952 * Enabled mutual authentication by default in SKE. If initiator
953 is not providing mutual authentication the responder will
954 force it. This will provide the proof of posession of the
955 private key for responder. The affected files are
956 lib/silcclient/protocol.c and silcd/protocol.c.
958 * Do not cache anymore the server's public key during SKE.
959 We do mutual authentication so the proof of posession of
960 private key is done, and if the server is authenticated in
961 conn auth protocol with public key we must have the public
962 key already. Affected file silcd/protocol.c.
964 * Added new global debug variable: silc_debug_hexdump. If
965 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
966 file lib/silcutil/silclog.[ch].
968 * Fixed compilation warning due to char * -> const char *.
969 Affected files lib/silcutil/silcnet.h, and
970 lib/silccore/silcauth.[ch].
972 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
974 * Fixed CMODE command when new channel key was created. If
975 the creation failed the old key was removed. Next time giving
976 same command would crash the server since the old key was
977 freed already. Affected file silcd/command.c.
979 * Fixed the silc_server_announce_get_channels to not crash
980 on reconnect. Affected file silcd/server.c.
982 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
984 * Added silc_log_set_debug_string function to set a regex
985 string to match for debug output. Only the function names,
986 or filenames matching the given debug string is actually
987 printed. This way it is possible to filter out those debug
988 strings that user is not interested in.
990 Fixed a bug in silc_string_regexify.
992 Affected files lib/silcutil/silclog.[ch], and
993 lib/silcutil/unix/silcunixutil.c.
995 * Changed the -d options in both server and Irssi SILC client
996 to take the debug string as argument. Affected files
997 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
999 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1001 * Added silc_hash_babbleprint to create a Bubble Babble
1002 Encoded fingerprint. The encoding is developed by Antti
1003 Huima (draft-huima-babble-01.txt), and it creates human
1004 readable strings out of binary data. Affected file
1005 lib/silccrypt/silchash.[ch].
1007 * Print the babble print now in addition of fingerprint as well
1008 in Irssi SILC client. Affected files are
1009 irssi/src/fe-common/silc/module-formats.[ch],
1010 irssi/src/fe-common/silc/core/client_ops.c.
1012 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1014 * Fixed a security problem found in SKE. The initiator's
1015 public key too is now added to the HASH hash value creation
1016 which is signed by the responder to create the SIGN value.
1017 This will prevent anyone in the middle to lie to the responder
1018 about the initiator's public key. If this is done now, the
1019 man in the middle will get caught. Updated the protocol
1022 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1024 * Better installation directory handling. Configure module
1025 paths and other paths automatically to example_silc* files
1026 in doc/. A patch by toma.
1028 * Fixed compiler warning from MPI library, and from SILC RNG.
1031 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1032 It can be configured with ./configure. A patch by toma.
1034 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1036 * Find correct make to use in prepare-clean. A patch by
1037 toma. Affected file prepare-clean.
1039 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1041 * Added irssi variables use_auto_addr, auto_bind_ip,
1042 auto_bind_port and auto_public_ip.
1044 * Changed the interface for silc_client_send_key_agreement
1045 in lib/silcclient/silcapi.h
1049 irssi/src/silc/core/silc-core.c
1051 lib/silcclient/silcapi.h
1052 irssi/src/silc/core/silc-channels.c
1053 lib/silcclient/client_keyagr.c
1056 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1058 * Added silc_pkcs_public_key_compare to compare two
1059 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1061 * Check that the client who set the founder mode on the
1062 channel is the same client that is giving the founder
1063 mode to itself. It is done by comparing the saved public
1064 key (it is saved even in the authentication is passphrase).
1065 Affected file silcd/command.c.
1067 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1069 * Do not process packet for disconnected socket connection.
1070 Affected file lib/silccore/silcpacket.c.
1072 * Process the DISCONNECT packet through scheduler in the
1073 client library. Affected file lib/silcclient/client.c.
1075 * Fixed the silc_client_packet_parse to not to increase
1076 the packet sequence number if the conn->sock and the
1077 current socket connection is not same. This can happen
1078 for example during key agreement when the conn includes
1079 multiple socket connections (listeners). Affected file
1080 lib/silcclient/client.c.
1082 * The sender of the file transfer request now provides also
1083 the pointer (listener) for the key exchange protocol. If
1084 the listener cannot be created then it sends empty key
1085 agreement and lets the receiver provide the listener.
1087 Added `local_ip' and `local_port' arguments to the
1088 silc_client_file_send. If they are provided they are used,
1089 if not then it will attempt to find local IP address, if
1090 not found or bind fails then the remote client will provide
1093 Affected files are lib/silcclient/client_ftp.c and
1094 lib/silcclient/silcapi.h.
1096 * Extended the FILE SEND command to support defining the
1097 local IP and port for key exchange listener. They are
1098 optional. Affected file irssi/src/silc/core/silc-servers.c.
1100 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1102 * Defined to WHOIS command reply the sending of fingerprint
1103 of the client's public key (if the proof of posession of the
1104 corresponding private key is verified by the server).
1105 Updated to the protocol specification.
1107 * Added support of receiving the client's public key's
1108 fingerprint in command reply in client library. Affected
1109 file is lib/silcclient/command_reply.c, and
1110 lib/silcclient/idlist.[ch].
1112 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1114 * Do not send over 128 chars long nickname to the server
1115 in NICK command. Affected file lib/silcclient/command.c.

1169 preserve the WHOWAS info for the client. Affected file
1170 silcd/server_util.c.
1172 * Fixed SERVER_SIGNOFF notify handling in the server. The
1173 server is now able to process incoming SERVER_SIGNOFF notify
1174 for a server that it doesn't even know about. It will remove
1175 the clients provided in the notify. Affected file
1176 silcd/packet_receive.c.
1178 * Check for partial packet in data queue after every packet that
1179 was found from the queue. Return and wait for more data if
1180 there is partial data in queue. Affected file is

1200 * Wrote a help file for FILE command.
1202 * Added silc_rng_global_get_byte_fast to get not-so-secure
1203 random data as fast as possible. Random data is read from
1204 /dev/urandom if available and from the SILC RNG if not
1205 available. It is used in padding generation. Affected file
1206 lib/silccrypt/silcrng.[ch].
1208 * All packets in client library are now processed synchronously.
1209 Optimized packet processing a lot. Affected file
1210 lib/silcclient/client.c.

1221 * Assure that silc_client_notify_by_server_resolve does not
1222 resolve the client information multiple times. If it cannot
1223 be found by the first it cannot be found at all. Affected
1224 file lib/silcclient/client_notify.c.
1226 * Fixed WHOWAS command reply calling. Affected file
1227 lib/silcclient/command_reply.c.
1229 * Removed all references to silc_idlist_get_client from the
1230 Irssi SILC client since that call is internal call used by
1231 the library. The Irssi SILC client will use now client
1232 retrieval functions found in silcapi.h.
1234 * Fixed a bug in resolving nickname info before sending
1235 private message. It used freed memory. Affected file
1236 irssi/src/silc/core/silc-servers.c.
1238 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1240 * Assure my_channels statistics cannot go negative in server.
1241 Affected files silcd/server.c, silcd/server_util.c.

1257 * Added silc_net_localip to return local host's IP address.
1258 Affected file lib/silcutil/silcnet.[ch].
1260 * If key exchange or rekey protocol is active for a connection
1261 parse all packets syncronously since there might be packets
1262 in packet queue that we are not able to process without first
1263 processing packets before them. Affected file silcd/server,
1264 lib/silcclient/client.c.
1266 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1267 whether library should continue processing the packet.

1314 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1315 is incomplete and is being resolved, it won't be resolved
1318 Make sure also that USERS command reply does not resolve
1319 twice information. Affected file is
1320 lib/silcclient/command_reply.c.
1322 Make sure that silc_client_get_clients_by_list does not
1323 resolve twice same information.
1325 * Check for valid client->id in the silc_server_free_client_data.
1326 Affected file silcd/server.c.
1328 * Fixed /GETKEY nick@server not to crash if the server entry
1329 is not found. Affected file lib/silcclient/command.c.
1331 * Fixed the silc_server_check_cmode_rights to check the

1339 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1341 * Call the silc_server_udpate_servers_by_server in the
1342 primary router that comes back online in the backup resuming
1343 protocol. Otherwise it routes packets wrong. Affected file
1344 silcd/server_util.[ch], silcd/server_backup.c.
1346 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1348 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1349 lib/silcutil/silcbuffmt.[ch].
1351 * Redefined the SILC packet header to include the padding
1352 length. Affected file lib/silccore/silcpacket.[ch].
1354 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1355 length for maximum padding up to 128 bytes). Affected
1356 file lib/silccore/silcpacket.h.
1358 * Removed all backwards support for old 0.5.x MAC thingies.
1359 The SILC packet header change makes it impossible to be
1360 backwards compatible.
1362 * Send the ENDING packet with timeout in the backup resuming
1363 protocol. This is to assure that all routers has connected
1364 to the primary router. Affected file silcd/server_backup.c.
1366 * Changed the RNG to take the first IV from random data. It
1367 used to take it from zero actually. Changed the RNG also
1368 to use /dev/urandom during session. /dev/random is used
1369 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1371 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1373 * Changed the SILC packet header to have the first two bytes
1374 (the packet length) encrypted. Affected files aroung the
1375 code tree, lib/silccore/silcpacket.[ch]. Removed the
1376 SilcPacketCheckDecrypt callback. It is not needed anymore
1377 since the silc_packet_receive_process will determine now
1378 whether the packet is normal or special.
1380 * Implemented the unidirectional MAC keys. Affected files
1381 lib/silcske/silcske.c, silcd/protocol.c and
1382 lib/silcclient/protocol.c.
1384 * Implemented the packet sequence number to the MAC computation.
1385 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1386 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1387 lib/silcclient/protocol.c.
1389 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1391 * Allow backup router to announce servers. All servers
1392 announced by backup router are added to the global list
1393 automatically. Update hte server's socket to our primary
1394 router also when backup router announces a server.
1395 Affected file silcd/packet_receive.c.
1397 * Do not update the client->router in the function
1398 silc_server_udpate_clients_by_server if the client is on
1399 global list. We might fail to find any specific server
1400 for locally connected clients and local cell clients. They
1401 should still use the `from' and not `to' as client->router.
1402 This fixes backup router resuming protocol. Affected file
1403 silcd/server_util.c.
1405 * Decrease channel statistics count only if the channel
1406 deletion worked. Affected files are silcd/server.c and
1407 silcd/server_util.c.
1409 * Added silc_server_update_servers_by_server to update origin
1410 of all server entries. Used during backup router protocol.
1411 Affected files silcd/server_util.[ch], silcd/server.c. and
1412 silcd/backup_router.c.
1414 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1415 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1416 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1417 lib/silccrypt/silchmac.c.
1419 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1421 * Assure that router cannot reroute the same channel message
1422 to the sender. Affected file silcd/packet_receive.c.
1424 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1426 * Made better checks that the channel message is not sent
1427 to the router it came from. Affected file is
1428 silcd/packet_send.c. Fixed memory leak too.
1430 * Announce informations for incoming router connection, but
1431 only after checking if it is replaced by backup router.
1432 Affected file silcd/packet_receive.c.
1434 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1436 * Fixed the backup resuming protocol to work in multiple
1437 router environment. Affected file silcd/server_backup.c.
1439 * Route packet only to one router in the function
1440 silc_server_packet_send_to_channel. Affected file is
1441 silcd/packet_send.c.
1443 * Fixed silc_server_send_notify_dest to set the broadcast
1444 flag. Fixed the silc_server_send_notify_topic to actually
1445 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1446 Affected file silcd/packet_send.c.
1448 * Changed the SFTP Filesystem interface. Changed the
1449 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1450 the filesystem operation function. The SilcSFTPFilesystem
1451 is now a context that is allocated by all filesystem allocation
1452 functions and it already includes the operations structure
1453 and filesystem specific context. It is given as argument
1454 now to the silc_sftp_server_start. This made the interface
1455 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1456 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1458 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1460 * Changed the backup router adding and getting interfaces
1461 in the server. The router that will be replaced by the
1462 specified backup router is now sent as argument. Affected
1463 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1466 * Added silc_net_addr2bin_ne to return the binary form of
1467 the IP address in network byte order. Affected files
1468 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1470 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1472 * Check for existing server ID in silc_server_new_server
1473 and in silc_server_connect_to_router_final and remove the
1474 old entry if it exists. Affected file silcd/packet_receive.c,
1477 * Send the channel message always to only one router, either
1478 in upstream or downstream. Affected file is
1479 silcd/packet_send.c.
1481 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1483 * Wrote the definition of the backup resuming protocol to the
1484 protocol specification.
1486 * Removed one redundant channel key generation from normal
1487 server during joining procedure. Removed one redundant
1488 channel key sending from server to router during joining
1489 procedure. Affected file silcd/command.c.
1491 * Made minor bugfixes to the backup router resuming protocol.
1492 Affected file silcd/server_backup.c, server.c.
1494 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1496 * Added --disable-asm configuration option. Affected files
1497 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1500 * Implemented the backup resuming protocol that is used to
1501 resume the primary router position in the cell after the
1502 primary router comes back online. Affected files
1503 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1504 and silcd/server_util.[ch].
1506 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1508 * Sleep two (2) seconds after sending QUIT command to server.
1509 Affected file lib/silcclient/command.c.
1511 * Assure that if outgoing data buffer is pending do not force
1512 send any data. Affected file silcd/packet_send.c.
1514 * Assure that if outgoing data buffer is pending do not force
1515 send any data. Affected file lib/silcclient/client.c.
1517 * Implemented the backup router support when the primary router
1518 goes down. The servers and routers can now use the backup
1519 router as new primary router without loosing connectivity.
1521 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1523 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1524 in the server to indicate disabled entry. All data read
1525 from the connection will be ignored and no data is sent
1526 for entry that is disabled. Affected files are
1527 silcd/idlist.h, silcd/server.c.
1529 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1531 * Created SFTP client and server test programs in the
1532 lib/silcsftp/tests directory.
1534 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1536 * Implemented memory filesystem (virtual filesystem) for
1537 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1540 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1542 * Implemented the SFTP (SSH File Transfer Protocol) to the
1543 lib/silcsftp. It includes SFTP client and SFTP server
1546 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1548 * Moved lib/silccore/silcprotocol.[ch] to the
1549 lib/silcutil library.
1551 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1552 take variable argument list pointer as argument. Affected
1553 file lib/silcutil/silcbuffmt.[ch].
1555 * Added silc_buffer_set function that is used to set data
1556 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1557 Affected file lib/silcutil/silcbuffer.h.
1559 * Changed various routines in the core library to use the new
1560 silc_buffer_set instead of allocating new buffer only for
1563 * Added 64-bit value formatting and unformatting support to the
1564 silc_buffer_[un]format routines. Affected file is
1565 lib/silcutil/silcbuffmt.[ch].
1567 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1568 to includes/bitmove.h.
1570 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Fixed channel user mode saving in client library. Affected
1573 file lib/silcclient/command[_reply].c.
1575 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1577 * Defined the file transfer to the SILC Protocol. Added
1578 new packet type SILC_PACKET_FTP and defined File Transfer
1579 Payload. The mandatory file transfer protocol is SFTP
1580 (SSH File Transfer Protocol). Affected file in addition
1581 of the internet draft is lib/silccore/silcpacket.h.
1583 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1584 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1585 is used as part of backup router protocol when the primary
1586 router of the cell is back online and wishes to resume
1587 the position as primary router.
1589 * Redefined the MAC generation keys in the protocol. The
1590 same key is not used anymore in both direction. Both
1591 direction will now use different keys for sending and
1592 receiving. This fixes a potential security flaw. This
1593 change causes incompatibilities in the protocol.
1595 * Redefined also the MAC computation from the packet.
1596 An packet sequence number is now added to the MAC
1597 computation. This prevents possible replay attacks against
1598 the protocol. This change too causes incompatibilities
1601 Added `sequence' field to the SilcPacketContext to hold
1602 the current sequence number for the packet.
1604 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1606 * Added `created' field to the SilcIDListData in the file
1607 silcd/idlist.h to indicate the time when the entry was
1610 * Added `created' field to the SilcChannelEntry too. Affected
1611 file silcd/idlist.h.
1613 * Added `creation_time' aguments to all the announcement functions
1614 in the server. If it is provided then only the entries that
1615 was created after the provided time frame are actually
1616 announced. Affected file silcd/server.[ch].
1618 * The protocol says that the Channel ID's IP address must be
1619 based on the router's IP address. Added check for this in
1620 the silc_server_new_channel when processing incoming New Channel
1621 Payload. Affected file silcd/packet_receive.c.
1623 * Print out the correct version with --version in SILC client.
1624 Affected file irssi/src/silc/core/silc-core.c.
1626 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1628 * Fixed WHOWAS command to check for completnes of the client
1629 entry always, not just when the command is coming from client.
1630 Affected file silcd/command.c.
1632 * Added new function silc_server_packet_queue_purge to purge the
1633 outgoing data queue to the network. After the function returns
1634 it is guaranteed that the outgoing packet queue is empty.
1635 Affected file silcd/packet_send.[ch].
1637 * Purge the outgoing packet queue in the rekey protocol's final
1638 callback to assure that all rekey packets go to the network
1639 before quitting the protocol. Affected file silcd/server.c.
1641 * Added silc_client_packet_queue_parse as similar function as
1642 in server to the client library. The affected file is
1643 lib/silcclient/client.c.
1645 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1647 * Splitted silcd/server.c and created silcd/server_util.[ch]
1648 for utility functions.
1650 * Added new socket flag SILC_SF_DISABLED to indicate that the
1651 connection is open but nothing can be sent to or received from
1652 the connection. Affected file lib/silcutil/silsockconn.[ch].
1653 The checking for disabled socket is checked in the low level
1654 silc_socket_write and silc_socket_read functions.
1656 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1658 * Allow only nicknames and channel names that fits into the
1659 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1661 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1663 * When processing JOIN command reply in server check that if
1664 the channel exists in our global list we'll move it the local
1665 list. Affected file silcd/command_reply.c.
1667 * Fixed the check whether client is joined on the channel already
1668 in JOIN command. Affected file lib/silcclient/command.c.
1670 * Fixed the JOIN command reply to check whether the channel
1671 already exists. Affected file lib/silcclient/command_reply.c.
1673 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1675 * Added silc_ske_status_string to map the SKE error numbers
1676 to readable strings. The affected files are
1677 lib/silcske/silcske[_status].[ch].
1679 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1681 * Do not show the private channels on the WHOIS channel list
1682 as it is not allowed by the protocol. The affected file is
1685 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1687 * Assure that the packet length digged from the actual packet
1688 is something sensible in the silc_packet_decrypt_rest_special
1689 in lib/silccrypt/silcpacket.c.
1691 * Free and NULL the allocated pointer in silc_hmac_alloc if
1692 the HMAC allocation fails. The affected file is
1693 lib/silccrypt/silchmac.c.
1695 * Print the selected security properties to the log files in
1696 the server. Affected file silcd/protocol.c.
1698 * Add SKE's reference counter even if calling the completion
1699 callback manually. Otherwise it goes negative, although it
1700 does not cause any problems. The affected file is
1701 lib/silcske/silcske.c.
1703 * Remove the client entry with short timeout after giving the
1704 KILL command. Affected file lib/silcclient/command.c.
1706 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1707 case all found clients are already disconnected (WHOWAS would
1708 found them) in the server. Affected file silcd/command.c.
1710 * Update the last_receive (time of last data received) to be
1711 updated only when received private or channel message so that
1712 the idle time showed in WHOIS makes more sense.
1714 * Added boolean field `valid' in to the SilcClientEntry in the
1715 client library to indicate whether the entry is valid or not.
1716 This fixes the nickname change bug on channel when changing
1717 the nickname to be same than the old (like nick to Nick) the
1718 nickname formatter doesn't set the new nick anymore to Nick@host.
1719 Affected file lib/silcclient/idlist.[ch].
1721 * Now actually fixed the nickname changing on disconnection.
1722 Added new function silc_change_nick to the Irssi SILC Client.
1723 Affected file irssi/src/silc/core/client_ops.c,
1724 irssi/src/silc/core/silc-nicklist.[ch].
1726 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1728 * Check that the public key exists in the GETKEY command before
1729 trying to encode it. Affected file silcd/command.c.
1731 * Print some notifications on received public keys with GETKEY
1732 command in the Irssi SILC Client. Affected files are
1733 irssi/src/fe-common/silc/module-formats.[ch],
1734 irssi/src/silc/core/client_ops.c.
1736 * Use IDENTIFY command to resolve the server information in the
1737 GETKEY command instead of INFO command. Affected file
1738 lib/silcclient/command.c.
1740 * All command reply functions in the client library now calls
1741 the pending command reply callbacks even if an error has
1742 occurred. The server has done this a long time and now it was
1743 time to move the client library to this as well. Now all
1744 errors can be delivered back to the pending command reply
1745 callbacks if necessary. Affected files are
1746 lib/silcclient/command[_reply].[ch].
1748 * Change the nickname on disconnection back to the username
1749 because in reconnect the server will enforce it to it anyway.
1750 Affected file irssi/src/silc/core/silc-servers.c.
1752 * Fixed a config file parsing bug in the Irssi SILC client.
1753 Affected file irssi/src/silc/core/clientconfig.c.
1755 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1757 * When printing the channel mode on JOIN, verify that the
1758 channel key and channel's HMAC are valid. Affected file
1759 irssi/src/silc/core/client_ops.c.
1761 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1763 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1764 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1765 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1767 * Removed channel key rekey task deleting from the function
1768 silc_server_save_channel_key. Affected file silcd/server.c.
1769 Added explicit timeout task context instead that is used to
1770 delete the task if we are registering a new task before the
1771 new task has elapsed.
1773 * When channel key rekey occurs the client library now saves
1774 the old channel key for a short period of time (10 seconds) and
1775 is able to use it in case some is still sending channel
1776 messages encrypted with the old key after the rekey. Affected
1777 file lib/silcclient/[idlist.h|client_channel.c].
1779 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1781 * Added check to the silc_server_new_id_real to not accept
1782 new ID if it is the sender's own ID. Affected file is
1783 silcd/packet_receive.c.
1785 * Assure that we do not announce ourself or the one we've
1786 sending our announcements when we're router and are announcing
1787 servers to our primary router. Affected file silcd/server.c.
1789 * Fixed silc_server_command_identify_check_client to assemble
1790 correct WHOIS packet. It send corrupted WHOIS packet and
1791 caused problem with router to router connections. Affected
1792 file silcd/command.c.
1794 Fixed also silc_server_command_whois_check the same way
1795 as for the IDENTIFY command.
1797 * Added new SilcIDListStatus to the server in the SilcIDListData
1798 structure. The status now includes the current status of
1799 the entry (like registered, resolved etc.). Affected file
1800 silcd/idlist.[ch]. Defined a bunch of different status types
1801 as well. This replaced the old boolean registered field as well.
1803 Added resolve_cmd_ident field to the SilcClientEntry structure
1804 too so that if the entry is for example being resolved so
1805 another command may attach to the same pending command reply
1806 without requiring to resolve the same entry again. This concept
1807 should optimize the WHOIS and the IDENTIFY resolving under
1808 heavy load by taking away unnecessary resolving for entries
1809 that are being resolved already.
1811 Added support for adding multiple pending commands for one
1812 command idenfier. Affected file silcd/command[_reply].[ch].
1814 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1815 before deleting the data. Otherwise the hash table will have
1816 freed data in comparison functions. Affected file is
1817 silcd/command_reply.c.
1819 * Fixed silc_idlist_replace_client_id to add the new entry to
1820 the cache with NULL nickname. Otherwise there will be invalid
1821 memory as the nickname after the nickname is freed. Affected
1822 file silcd/packet_receive.c.
1824 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1825 saved into wrong slots because the previous number of entries
1826 was not taken into account. Affected file silcd/idlist.c.
1827 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1829 * If we are router and we receive JOIN notify to a channel that
1830 does not have any users then notified client is marked as the
1831 channel founder, as it is it. The affected file is
1832 silcd/packet_receive.c
1834 * Added to the extended hash table API's table_del_*ext functions
1835 the destructor as argument too, so that the caller can decide
1836 which destructor to use or whether to use destructor at all.
1837 Affected file lib/silcutil/silchashtable.[ch].
1839 * Fixed ID Cache purging. It actually deleted the entries from
1840 the hash table after the data was freed. The hash table ended
1841 up comparing freed memory. The affected file is
1842 lib/silccore/silcidcache.c.
1844 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1846 * Fixed Irssi SILC client's KILL command's HELP syntax.
1848 * The USERS command now resolves the detailed user information
1849 if the userinfo field is missing. Affected file is
1850 lib/silcclient/command_reply.c.
1852 * Do not print error in silc_file_read if the read file does
1853 not exist. Just silently return NULL. Affected file is
1854 lib/silcutil/silcutil.c.
1856 * Fixed the silc_log_output to not wine about NULL filename
1857 and to not create some bogus " " filename. Affected file is
1858 lib/silcutil/silclog.c.
1860 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1862 * Fixed various printing bugs on the user interface in the
1863 Irssi SILC Client. Minor changes that were forgotten from
1866 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1868 * Fixed the configure.in.pre and the compilation and distribution
1869 environment to support the new autoconf 2.52. That version is
1870 now required to compile the CVS trunk.
1872 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1875 to generally parse user@fqdn format strings. Affected file
1876 lib/silcutil/silcutil.c.
1878 * Added nickname_format and nickname_force_format fields to the
1879 SilcClientParams structure. The first one defines the format
1880 for the nicknames that the library will enforce if the receives
1881 multiple same nicknames. The second one is boolean value and
1882 can be used to force the library to always enforce the format
1883 to the nicknames regardles whether there are multiple nicknames
1884 or not. This configurable formatting was employed to flexibly
1885 support accessing multiple nicknames from the user interface.
1886 The userinterface can now set the nicknames to what ever format
1887 they prefer. Affected file lib/silcclient/silcapi.h.
1889 Added function silc_client_nickname_format to the file
1890 lib/silcclient/idlist.c. It performs the nickname formatting.
1892 Added new field `hostname´ to the SilcClientEntry context.
1893 It holds the hostname of the client. Affected file is
1894 lib/silcclient/idlist.h.
1896 * Irssi SILC Client sets the nicknames in nick@hostn format.
1897 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1898 irssi/src/silc/core/silc-core.c.
1900 The WHOIS printing now also shows both the real nickname and
1901 the formatted nickname so that user knows how to access the
1902 user if there are multiple same nicknames cached. Affected
1903 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1904 printing formatting too to take the hostname now as a separate
1905 argument. The Affected file is
1906 irssi/src/fe-common/silc/modules-formats.[ch].
1908 * Changed the silc_client_get_clients_local to accept the formatted
1909 nickname as argument. It accepts the real nickname too but the
1910 formatted nickname can be used to find the true entry from
1911 multiple entries. Affected file lib/silcclient/silcapi.h and
1912 lib/silcclient/idlist.c.
1914 * Added nickname_format_parse field to the SilcClientParams.
1915 It is a callback function provided by the application to parse
1916 the nickname out of the formatted nickname string. The library
1917 calls it to get the nickname from the formatted string. Since
1918 the application generally knows better the format of the nickname
1919 string it parses it instead of the library, even though library
1920 encodes the formatted string. If the callback function is not
1921 provided then the library will use the string as is. The
1922 affected file is lib/silcclient/silcapi.h.
1924 * All the nickname strings passed to the client library in
1925 commands are now expected to be formatted nickname strings.
1926 If the command does not support the formatted nickname string
1927 it will assume that the sent string is the actual nickname.
1928 Affected file lib/silcclient/command.c.
1930 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1932 * Added public key authentication support to OPER and SILCOPER
1933 commands in the client library. Affected file is
1934 lib/silcclient/command.c.
1936 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1938 * Changed the get_auth_methdod client operation to be asynchronous.
1939 It can be async if the application resolves the authentication
1940 method from the server during the negotiation. Added new
1941 SilcGetAuthMeth completion callback that the application will
1942 call after resolving the authentication method.
1944 Added function silc_client_request_authentication_method that
1945 the application can use to resolve the authentication method
1946 from the server. Added also SilcConnectionAuthRequest callback
1947 that the library will call after the server has replied. The
1948 application can call this function if it does not know the
1949 current authentication method.
1951 Affected files are lib/silcclient/client.c and
1952 lib/silcclient/silcapi.h.
1954 * The Irssi SILC client now automatically resolves the authentication
1955 method incase any configuration information is not present (and
1956 currently there never is). The affected file is
1957 irssi/src/silc/core/client_ops.c.
1959 * Fixed public key authentication from the client library.
1960 Affected file lib/silcclient/protocol.c. Changed also the
1961 protocol specification about the public key authentication in
1962 the connection authentication protocol. The actual data to be
1963 signed is now computed with a hash function before signing.
1965 * Fixed the public key authentication from the server as well.
1966 Affected file silcd/protocol.c.
1968 * Removed the mlock()'s from the memory allocation routines.
1969 Affected file lib/silcutil/silcmemory.c. The ./configure does
1970 not check anymore for the mlock(). Affected file is
1973 * Fixed USERS command in server to allow the execution of the
1974 command for private and secret channels if the client sending
1975 the command is on the channel. Affected file silcd/command.c.
1977 * Fixed silc_client_get_clients_local to return the clients
1978 count correctly. It could return wrong value. Affected file
1979 lib/silcclient/idlist.c.
1981 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1983 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1984 types. The assembler optimizations seemed not to like 64-bit
1985 data types. The assmebler optimizations thus are now enabled
1986 also for BSD systems as opposed to only enable them for Linux.
1988 * Do not check for threads at all on BSD systems. Affected
1989 file configure.in.pre.
1991 * Removed -n and -h options from the Irssi SILC Client since
1992 they are not used in silc.
1994 * Fixed the prime generation to assure that the first digit
1995 of the generated random number is not zero since our conversion
1996 routines does not like number strings that starts with zero
1997 digit. If zero digit is seen the random number is regenerated.
1998 This caused some corrupted RSA keys when the zero first digit
1999 was met. Affected file lib/silcmath/silcprimegen.c.
2001 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2003 * Fixed WIN32 configuration in the ./configure script.
2004 Fixed to include xti.h on environments that has it.
2005 Patches by Carsten Ilchmann and andrew.
2007 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2009 * Changed the silc_id_create_client_id to be collision
2010 resistant. It is now assured that there cannot be created
2011 two same client ID's. I suspect that some weird bugs in
2012 the server were actually caused by duplicate Client IDs.
2013 Affected file silcd/serverid.[ch]. A router receiving
2014 new ID now also assures and informs the sending server
2015 if the ID caused collision.
2017 * Changed the silc_id_create_channel_id to also assure that
2018 there are no collisions.
2020 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2022 * Statement about ignoring the Mutual Authentication flag when
2023 performing rekey with PFS was a bit misleading. It is ignored
2024 if it was set in the initial negotiation, it cannot be even
2025 set in the rekey. Fixed in the ke-auth draft. Started the
2026 new versions of the protocol drafts in the doc/.
2028 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2030 * Fixed a bug in silc_client_command_identify_save when saving
2031 new channel information. The channel name was no duplicated
2032 and caused crash on exit. Affected file is
2033 lib/silcclient/command_reply.c.
2035 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2037 * Fixed the getkey command handling in the server. Send just
2038 empty OK reply to the sender if the key could not be fetched
2039 (but everything else was ok, like the key just was not available).
2040 Changed the public key parameter to optional in the protocol
2041 specs so that empty OK reply can be sent. Affected file
2044 Added a message to Irssi SILC client to tell to user if the
2045 server did not return a public key.
2047 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2049 * Fixed a channel key regeneration bug. It registered new
2050 timeout tasks exponentially until all system resources were
2051 used. Affected file silcd/server.c.
2053 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2055 * Added the SILC Document generator to the scripts/silcdoc.
2056 It can be used to generate the Toolkit Reference Manual out
2057 of the source tree. Internally it will also use the RoboDoc
2058 generator now imported in util/robodoc.
2060 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2062 * Added couple of return's in rekey protocol if error orccurred
2063 during the protocol. The execution must be terminated.
2064 Affected file silcd/protocol.c. Also, terminate the protocol
2065 always with timeout.
2067 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2069 * The client's Client ID was created initally from the wrong
2070 nickname (it could have been in format nick@host) in the
2071 silc_server_new_client. Affected file silcd/packet_receive.c
2073 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2075 * Added some SILC_LOG_ERROR's to various error conditions
2076 if client could not be added to ID cache. Affected files
2077 silcd/packet_receive.c and silcd/server.c.
2079 * When client's sock->user_data is freed, NULL also the
2080 client->router and client->connection pointers. Added check
2081 for these pointers being NULL to various places around the
2082 code. Affected file silcd/server.c.
2084 * Added client->data.registered == TRUE checks to various
2085 places around the code to assure that unregistered client's
2086 are not handled when it is not allowed. Affected file
2089 * Added `bool registered' fields to all
2090 silc_idlist_[server|client]_get_* routines to indicate whether
2091 the fetched client needs to be registered or not. Affected
2092 file silcd/idlist.[ch].
2094 * Add your own entry as registered to the ID cache in the
2095 server. Affected file server.c.
2097 * Fixed a bug in silc_server_new_server. The SilcServer was
2098 set as the new server's context instead of SilcServerEntry.
2099 This naturally caused some weird bugs.
2101 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2103 * Do not delete the channel rekey task when adding it
2104 for in silc_server_create_channel_key.
2106 * Changed the silc_server_create_channel_key to return
2107 TRUE or FALSE to indicate the success of the channel key
2110 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2112 * Fixed MSVC++ project files and added missing files to
2113 Makefiles under win32/.
2115 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2117 * Do not add TCP_NODELAY flag if the operating system
2118 does not have it defined. Affected files are
2119 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2121 * Fixed buffer overflow from Irssi SILC Client. Affected
2122 file irssi/src/fe-common/core/themes.c.
2124 * Fixed double free in client library in the file
2125 lib/silcclient/client.c when disconnecting from server.
2127 * Applied double free patch from cras to Irssi SILC client.
2128 Affected files irssi/src/core/[modules/expandos].c
2130 * Fixed the disconnection handling to Irssi SILC Client.
2131 The application must call silc_client_close_connection
2132 in ops->connect client operation in case of failure of
2133 the connection. Affected file is
2134 irssi/src/silc/core/client_ops.c.
2136 * Do not set sock->protocol to NULL in the function
2137 silc_client_close_connection after executing the protocol's
2138 final callback since the sock might not be valid anymore.
2139 Affected file lib/silcclient/client.c.
2141 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2143 * Do not enable SILC_THREADS if the linking with libpthread
2144 did not happen. Affected file configure.in.pre.
2146 * Added notion to protocol specification that server must
2147 verify the sent authentication payload with CMODE when
2148 setting the channel founder key. Implemented it to the
2149 server. Affected file silcd/command.c.
2151 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2153 * Added _EXTRA_DIST SILC distribution variable to the
2154 distributions file. It is used to conditionally add extra
2155 files or directories to the specific distribution. Affected
2156 files ./prepare, Makefile.am.pre and distributions.
2158 Removed the `_' from the start of the distribution names.
2161 * Added README.WIN32 for instructions to compile the Toolkit
2164 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2166 * Fixed a double free in disconnection in the server. Affected
2167 file is silcd/server.c.
2169 * Fixed the lib/silcske/groups.c to work now also with GMP
2170 MP library. The string conversion did not work when using
2171 specific base and the base is indicated in the string as well.
2173 * Created win32/ directory which now includes MSVC++ specific
2174 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2175 It will appear only in the toolkit distribution
2177 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2179 * Changed the key material distribution function in case when
2180 the hash output is too short. The data is now concatenated
2181 a bit differently than it used to. Made the change to the
2182 SKE protocol specification.
2184 * Added better GMP detection to configure.in.pre. A patch
2187 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2189 * Fixed a minor bug in SKE that might cause some problem on
2190 some platforms. Affected file lib/silcske/silcske.c.
2192 * Added the cookie checking for initiator in the SKE. It checks
2193 that the responder returns the sent cookie unmodified. The
2194 affected file is lib/silcske/silcske.c. Added new SKE
2195 error type INVALID_COOKIE that can be sent during the
2196 negotiation. Fixed some memory leaks as well.
2198 * Added the "invalid cookie" error message to Irssi SILC client's
2201 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2203 * Added `task_max' field to the SilcClientParams to indicate
2204 the maximum tasks the scheduler can handle. If set to zero,
2205 default values are used. Affected file lib/silcclient/silcapi.h.
2207 * Fixed memory leaks in silc_client_close_connection. Affected
2208 file lib/silcclient/client.c.
2210 * Added silc_client_del_client_entry to client library to free
2211 all memory of given client entry. Affected file is
2212 lib/silcclient/idlist.[ch].
2214 * Added new functions silc_client_del_channel and
2215 silc_client_del_server to delete channel and server entries.
2216 Affected file lib/silcclient/[silcapi.h/idlist.c].
2218 * Removed silc_client_del_client_by_id from silcapi.h.
2220 * Fixed the INFO command to return the server's own info
2221 correctly when querying by Server ID. Affected file is
2224 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2226 * Removed the non-blocking settings in WIN32 code in the
2227 silc_sock_[read/write] and added SleepEx instead. Affected
2228 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2229 of input data is now checked with FIONREAD and ioctlsocket.
2231 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2233 * Call silc_schedule_task_del_by_context in the
2234 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2235 Affected file lib/silccore/silcprotocol.c.
2237 * Call silc_protocol_cancel for active protocols in the
2238 silc_server_close_connection if the funtion
2239 silc_server_free_sock_user_data has not been called.
2240 Affected file silcd/server.c.
2242 * Generic tasks cannot be deleted using the del_by_fd
2243 task deleting function since generic tasks does not match
2244 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2246 * Added a notion to SILCOPER help file that the SILCOPER works
2247 only on router server, not on normal server.
2249 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2251 * Added for WIN32 support for the new scheduler as well.
2252 Affected file lib/silcutil/win32/silcwin32schedule.c.
2254 * Fixed the SHA1 implementation to work on various platforms.
2256 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2258 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2259 API. It is part of the scheduler now. Everything else is
2260 as previously but some functions has changed their names.
2261 Checkout the lib/silcutil/silcschedule.h for the interface.
2262 Updated all applications to use the new interface. Affected
2263 files are lib/silcutil/silcschedule.[ch].
2265 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2267 * Found a bug in the SKE implementation. The HASH value,
2268 specified by the protocol, was not computed correctly. The
2269 public key of the responder was not added to the computation
2270 even though it is mandatory. Affected file lib/silcske/silcske.c.
2271 This unfortunately causes incompatibilities with older
2272 clients and servers.
2274 * Added WIN32 specific network init and uninit functions:
2275 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2276 the Winsock2. Affected file lib/silcutil/silcnet.h and
2277 lib/silcutil/win32/silcwin32net.c.
2279 * Set the socket always to nonblocking mode on WIN32 after
2280 reading data or writing data. Affected file is
2281 lib/silcutil/win32/silcwin32sockconn.c.
2283 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2285 * Fixed various compilation problems under WIN32. Affected
2286 files lib/silcutil/win32/silcwin32thread.c and
2287 lib/silcutil/win32/silcwin32schedule.c.
2289 * Removed all _internal.h #includes from public header
2290 files. Internal headers must never be included from
2293 Removed also the lib/silcske/payload_internal.h file.
2295 * All include files that may be needed (public and some others
2296 included by the public headers) by application developers are
2297 now copied to the ./includes directory. It does not copy any
2298 internal headers. Affected file Makefile.defines.pre and all
2299 Makefile.am's under lib/ and subdirs.
2301 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2303 * Do not change the ~/.silc directory's permissions automatically.
2304 Affected file irssi/src/silc/core/clientutil.c.
2306 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2308 * Do not cancel the protocol in silc_server_close_connection
2309 it might cause recursion. Now cancelled in the function
2310 silc_server_free_sock_user_data. Affected file silcd/server.c.
2312 * Fixed the silc_server_remove_clients_by_server to regenerate
2313 the channel keys correctly finally. Added also new function
2314 silc_server_remove_clients_channels to actually do it.
2315 Affected file silcd/server.c.
2317 * Fixed the silc_server_new_channel to not crash by giving
2318 wrong router to the new channel. Affected file is
2319 silcd/packet_receive.c.
2321 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2323 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2324 which is given as argument to the silc_client_alloc now.
2325 It can be used to configure the client and set various parameters
2326 that affect the function of the client.
2328 * The USERS command in server did not check whether the channel
2329 is private or secret. Affected file silcd/command.c.
2331 * Added new argument to the USERS command in protocol specification.
2332 The USERS command now can take the channel name as argument
2333 as well. Added support for this in client and server and
2334 updated the protocol specs.
2336 * Completed the GETKEY command in client. It can be now used
2337 to fetch also servers public key not only some clients.
2338 Affected files lib/silcclient/command[_reply].c.
2340 * Added silc_client_get_server to return server entry by the
2341 server name. Affected files lib/silcclient/silcapi.h and
2344 * Redefined the IDENTIFY command in protocol specification to be
2345 more generic. It now can be used to query information about
2346 any entity in the SILC Network, including clients, servers and
2347 channels. The query may be based either the entity's name
2348 or the ID. Added support for this in both client and server.
2350 Affected files silcd/command.c and lib/silcclient/command.c
2351 and command_reply.c.
2353 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2354 the _from_client and _from_server functions. Affected file
2357 * Added silc_client_get_channel_by_id_resolve to the file
2358 lib/silcclient/silcapi.h to resolve channel information by
2359 its ID. Added also silc_client_get_channel_by_id that
2360 does not resolve it from the server.
2362 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2364 * Added SilcServerEntry context into the client library
2365 to represent one server. The INFO command now allocates
2366 these to save the resolved server info. For now on the
2367 client library will also keep information about servers,
2368 connected and resolved with INFO.
2370 The INFO command now allocates the SilcServerEntry context
2371 and saves the server info there. The COMMAND_REPLY in
2372 the INFO now returns the parameters to application in
2373 same order as defined in the protocol specification.
2375 The entries are cached in the client->server_cache.
2377 * The INFO command is now issued after received the Client ID
2378 from the server. Affected file lib/silcclient/client.c.
2380 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2381 to the application as the mode changer might be server.
2382 It is guaranteed that NULL is not returned anymore to the
2383 application. Affected file lib/silcclient/client_notify.c.
2385 The ID Type is now also passed to the application so that
2386 it can check whether the returned entry is SilcClientEntry
2389 Added new function silc_client_get_server_by_id to return
2390 the server entry by ID. Affected files are the
2391 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2393 * Do not create the channel in the Irssi SILC Client when issuing
2394 the JOIN command but when received the sucessful JOIN command
2395 reply. Otherwise the channel might get created even though we
2396 could not join it. The Affected file is
2397 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2399 * Fixed a channel joining bug in router. The router must also
2400 check the channel modes, invite and ban lists etc. when serving
2401 the JOIN command sent by normal server. Affected file is
2402 silcd/command.c. The router now resolves the client's
2403 information from the server who sent the JOIN command if it
2404 does not know it, and processes the JOIN command only after
2407 * Changed the SilcCommandCb to take new argument; void *context2.
2408 Affected file lib/silccore/silccommand.h
2410 The second argument in the command callbacks in the server now
2411 includes the SilcServerCommandReplyContext if the command was
2412 called as pending command callback from the command reply.
2413 Otherwise it is NULL. When called as pending the status of the
2414 command reply will be checked and if it was erronous the
2415 error will be sent to the original sender of the command.
2416 This way the client always receives the error messages even
2417 though the server was actually the one who received the error
2418 when it resent the command to router, for example. Affected
2419 files silcd/command[_reply].[ch].
2421 * Fixed sending WHOWAS command's error message to client if
2422 the requested client could not be found. It was missing.
2425 * Changed the CMODE and CUMODE commands reply arguments in the
2426 protocol specification. The Channel ID is now sent in both
2427 of the commands to identify the channel. Implemented this
2428 new feature to the client and server. Affected files
2429 lib/silcclient/command_reply.c and silcd/command.c.
2431 * Made better checks for invite and ban lists in the JOIN
2432 command in server. Affected file silcd/command.c.
2434 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2436 * The server now performs the incoming host IP/DNS lookup
2437 using the silc_socket_host_lookup and thus does not block
2438 the server anymore. Affected file silcd/server.c.
2440 * Completed the multi-thread support for SILC Scheduler in
2441 the lib/silcutil/silcschedule.c.
2443 * Fixed the configure.in.pre to detect the pthread correctly
2446 * Fixed a deadlock in silc_task_queue_wakeup in the file
2447 lib/silcutil/silctask.c.
2449 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2451 * Added new function silc_schedule_wakeup that is used in
2452 multi-threaded environment to wakeup the main thread's
2453 schduler. It needs to be used when a thread adds a new task
2454 or removes a task from task queues. After waking up, the
2455 scheduler will detect the task queue changes. If threads
2456 support is not compiled in this function has no effect.
2457 Implemented the wakeup mechanism to both Unix and WIN32
2458 systems. Affected files are lib/silcutil/silcschedule.[ch],
2459 lib/silcutil/unix/silcunixschedule.c and the
2460 lib/silcutil/win32/silcwin32schedule.c.
2462 * Added new function silc_task_queue_wakeup to wakeup the
2463 scheduler by the specified task queue. Affected file
2464 lib/silcutil/silctask.[ch].
2466 * The silc_socket_host_lookup_start now wakes up the scheduler
2467 after adding the timeout task. Affected file is
2468 lib/silcutil/silcsockconn.c.
2470 * The silc_socket_host_lookup is synchronous now if the threads
2471 support is not compiled in. However, the callback is still
2472 called asyncronously through the scheduler, anyway. Affected
2473 file lib/silcutil/silcsockconn.c.
2475 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2477 * Added new function silc_socket_host_lookup to perform
2478 asynchronous IP and FQDN lookups for the socket connection.
2479 Affected files lib/silcutil/silcsockconn.[ch].
2481 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2483 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2484 that may or may not compile the mutex support in.
2486 Changed the silc_mutex_alloc interface. It allocates the
2487 mutex now to the sent pointer and returns TRUE or FALSE.
2489 Affected file lib/silcutil/silcmutex.h.
2491 * Wrote the SILC Task Queue interface to support multi-threads.
2492 Affected file lib/silcutil/silctask.[ch].
2494 * Wrote the SILC Scheduler to support multi-threads. Affected
2495 file lib/silcutil/silcschedule.c.
2497 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2499 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2500 in lib/silcutil/win32/.
2502 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2504 * Defined SILC Mutex API and SILC Thread API and implemented
2505 them for Unix. Affected files are
2506 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2507 lib/silcutil/unix/silcunixmutex.c and
2508 lib/silcutil/unix/silcunixthread.c.
2510 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2512 * Fixed the silc_server_remove_clients_by_server's channel
2513 key re-generation. The hash table handling was incorrect
2514 and would not work with many channels. Affected file is
2517 * Fixed some memory leaks around the server code.
2519 * Rewrote the silc_server_get_users_on_channel to support IPv6
2520 based Client ID's. Affected file silcd/server.c.
2522 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2523 specification. However, a separate document must be written
2524 to define the detailed signing procedure and the payload
2525 associated with the flag. Defined the flag to the
2526 lib/silccore/silcchannel.h as well.
2528 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2530 * Changed the dynamic tables to static size tables in the
2531 lib/silccrypt/silchmac.c.
2533 * Removed GCC dependencies from the code. A patch by cras.
2535 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2537 * Do not show the error "Error receiving packet bla bla"
2538 in server if it really was not an error (-2 means that reading
2539 is pending). Affected file silcd/server.c.
2541 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2543 * Fixed a possible crash in silc_server_remove_clients_by_server
2544 in silcd/server.c. Fixed there also some memory leaks.
2546 * Fixed the silc_idlist_replace_client_id. It could replace
2547 wrong key in the hash table. Affected file silcd/idlist.c.
2549 * Do not check whether there are global users on the channel
2550 if the channel->global_users is FALSE. Affected functions
2551 silc_server_remove_from_one_channel and
2552 silc_server_remove_from_channels in silcd/server.c. Also,
2553 do not check if the removed client is local as we can be
2554 sure that global client was not removed from the channel
2555 and checking for global users is not needed.
2557 * The silc_server_remove_clients_by_server now re-generates
2558 the channel keys correctly for those channels that had
2559 clients removed from them. Affected file silcd/server.c.
2561 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2563 * Found the reason of random crashes in the server. We weren't
2564 ignoring the SIGPIPE signal (which can be sent in write())
2565 and it crashed the server. Affected file silcd/silcd.c.
2567 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2569 * Assure that sock->user_data is not NULL in the function
2570 silc_server_packet_send in silcd/packet_send.c.
2572 * Disconnect the remote connection if it could not be added
2573 to any ID lists in the server. The affected file is
2576 * Check in silc_server_packet_send[_real/dest] that the
2577 socket is not disconnecting and ignore the data if it is.
2578 Affected file silcd/packet_send.c.
2580 * Define inline to __inline on native WIN32 compilation.
2581 Affected file includes/silcwin32.h.
2583 * Added some explicit type casts for inline code since MSVC
2584 require them. Affected files lib/silcutil/silcbuffer.h,
2585 lib/trq/silcdlist.h and lib/trq/silclist.h.
2587 * Print warning in log files from now on if the packet
2588 decryption fails. Affected file silcd/server.c.
2590 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2592 * Changed the `say' client operation's interface to accept
2593 new `type' argument to indicate the type of the message sent
2594 by the library. The application may filter the library's
2595 messages according the type. The affected file is the
2596 lib/silcclient/silcapi.h.
2598 * Added two new functions to lib/silcclient/silcapi.h:
2599 silc_client_del_client and silc_client_del_client_by_id.
2600 Affected file lib/silcclient/idlist.c.
2602 * Moved the clientincludes.h from includes/ to silc/ and
2603 serverincludes.h from includes/ to silcd/.
2605 * The modes for the CMODE and CUMODE are now passed as
2606 uint32 for application with COMMAND_REPLY. The affected
2607 file is lib/silcclient/command_reply.c.
2609 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * /WHOIS without arguments shows client's own information.
2612 Affected file lib/silcclient/command.c.
2614 * Changed PING to not accept any arguments. The specs
2615 says that client can ping only the connected server so
2616 requiring an argument is not needed. Affected file is
2617 lib/silcclient/command.c.
2619 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2621 * Fixed a fatal bug in private message sending and reception
2622 encryption and decryption when using private message keys.
2623 The implementation was incorrect and did not follow the
2624 specification. It causd that some of the message were
2625 lost since it did not use the sending and receiving keys
2626 as the protocol suggests. This has been fixed and will cause
2627 incompatibilities with older clients when sending private
2628 message encrypted with private message keys. Affected files
2629 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2630 and various other in Irssi SILC Client.
2632 Added `responder' boolean argument to the functions
2633 silc_client_add_private_message_key[_ske] to indicate when
2634 the key is added as responder or initiator of the key
2637 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2639 * Removed the silc_ske_check_version function and created
2640 a SilcSKECheckVersion callback. Added also a function
2641 silc_ske_set_callbacks that is now used to set all SKE
2642 callbacks. The callback functions are not given to
2643 the SKE functions anymore, but this function is used to
2646 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2648 * Added `silc_version' argument to the silc_client_alloc
2649 to define the version of the application for the library.
2650 The library will use the version string to compare it
2651 against the remote host's (usually a server) version
2652 string. Affected file lib/silcclient/silcapi.h
2654 * Added the KE protocol context to Key Agreement context
2655 in client library so that we can abort the SKE if it
2656 is in process when we get timeout. Affected file is
2657 lib/silcclient/client_keyagr.c.
2659 * Do not resolve the client ID forever if it returns in the
2660 first time that such client does not exist. This was done
2661 for example with private message. Affected file is
2662 lib/silcclient/client_prvmsg.c.
2664 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2666 * Do not add regex.h for WIN32. The affected file
2667 includes/silcincludes.h.
2669 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2670 not work yet 100%. It generates the DLL's automatically
2671 when compiling with --with-win32 under cygwin.
2673 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2675 * lib/contrib/regex.c is not compiled on WIN32.
2677 * Added silc_net_get_socket_opt function to the
2678 lib/silcutil/silcnet.h.
2680 * Added includes/silcwin32.h for WIN32 specific includes
2683 * Do not use ptime structure or any of the posix process
2684 functions on WIN32 in lib/silccrypt/silrng.c.
2686 * Added silc_gettimeofday to provide generic function
2687 for struct timeval on all platforms. Added the function
2688 to lib/silcutil/silcutil.h.
2690 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2692 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2693 library as they clearly belong there. As a plus side we
2694 can make the actual socket connection routines platform
2697 Added also new generic function silc_socket_read and
2698 silc_socket_write (that used to be silc_packet_[read/write].
2699 The implementation of these are platform specific.
2701 * Added WIN32 specific routines of silc_socket_[read/write]
2702 to lib/silcutil/win32/silcwin32sockconn.c.
2704 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2706 * Added preliminary support for native WIN32 compilation under
2707 cygwin (using the -mno-cygwin option for GCC) to the
2708 ./configure.in.pre. The --with-win32 now prepares the
2709 compilation for native WIN32.
2711 * Rewrote the SILC Scheduler interface in the file
2712 lib/silcutil/silcschedule.h. The scheduler is now context
2713 based and does not have anymore any global static scheduler.
2714 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2715 and created lib/silcutil/win32 directory for WIN32 based
2718 * Added Unix specific network routines to the
2719 lib/silcutil/unix/silcunixnet.c and the old
2720 lib/silcutil/silcnet.c includes now only generic routines.
2722 Added WIN32 specific network routines to the
2723 lib/silcutil/win32/silcwin32net.c.
2725 * Added Unix specific utility functions from the
2726 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2728 * Added WIN32 SILC Scheduler to the file
2729 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2732 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2734 * Do not handle JOIN notify in the server if the target client
2735 is not registered (idata->registered == FALSE). The affected
2736 file is silcd/packet_receive.c.
2738 * Update the nickrec->founder in event_cumode in the Irssi SILC
2739 client. Affected file irssi/src/silc/core/silc-channels.c.
2741 * Fixed the CUMODE_CHANGE notify handling in the server when
2742 server and router are announcing their clients on channels.
2743 Now the mode changes are saved and notified correctly. The
2744 affected file is /silcd/packet_receive.c.
2746 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2747 They really did not replace the cache entry in the ID Cache.
2748 Now they do that. Affected file silcd/idlist.c.
2750 * Fixed the KICK notify handling in the Irssi SILC client to
2751 update the channel records so that the kicked client does not
2752 appear to be on the channel. The affected file is
2753 irssi/src/silc/core/silc-channels.c.
2755 * Always update the conn->current_channel when executing command
2756 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2758 * Fixed the KILL notify handling in Irssi SILC client to remove
2759 the killed client on all channels.
2761 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2763 * Fixed the silc_parse_command_line to remove extra spaces
2764 from the start and end of the arguments. Affected file is
2765 lib/silcutil/silcutil.c.
2767 * Cancel and free any active protocol in the function
2768 silc_server_close_connection. Affected file silcd/server.c.
2770 * Cancel and free any active protocol in the function
2771 silc_client_close_connction. Affected file is
2772 lib/silcclient/client.c.
2774 * Do not execute the KILL command for clients that are in
2775 history (ie. they are not in the network). Affected file is
2778 * Fixed KILL notify handling, client does not crash anymore.
2779 Affected file irssi/src/silc/core/silc-channels.c.
2781 * Reduced the default packet buffer size from 2048 to 1024 in
2782 lib/silccore/silcpacket.c.
2784 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2785 counter to the SKE context that is incresed when the SKE library
2786 performs async operation outside the library. If the outside
2787 process frees the SKE context and FREED status will be set
2788 and the library will detect after the sync operation that the
2789 libary is freed. The affected files are
2790 lib/silcske/silcske[_status].[ch].
2792 * Resolve the client entry information in the function
2793 silc_client_channel_message to assure that NULL pointer is not
2794 passed as client entry to the application. */
2796 * Fixed the task timeout calculation to assure that there is
2797 never negative timeouts. The affected file is
2798 lib/silcutil/silcschedule.c.
2800 * Fixed the channel user mode notification sending in server.
2801 It was sent point-to-point to the router (or to server by router)
2802 but it needs to be destined to a channel. The routines now
2803 supports sending the channel user mode notifys to the channels
2804 when announcing clients and channels. Affected files are
2805 silcd/server.c and silcd/packet_receive.c.
2807 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2808 It did not actually replace the old channel entry in the cache.
2809 Affected file lib/silcclient/client_notify.c.
2811 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2813 * Fixed a possible crash in silc_packet_send_prepare. It now
2814 assures always that there is enough space in the buffer and
2815 at the tail area of the buffer (for MAC).
2817 Fixed the inbound buffer reallocation in silc_packet_read.
2818 It was old code and did not handle the reallocation correctly.
2821 The affected file is lib/silccore/silcpacket.c.
2823 * Fixed buffer overflow in silc_parse_nickname in the file
2824 lib/silcutil/silcutil.c.
2826 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2828 * make install generates new server keys only if there is not
2831 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2833 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2834 Added check that if the NOREPLY is set then we will not send
2835 the away message. This avoids infinite loop of away messages
2836 if both clients are away. The affected file is
2837 lib/silcclient/client_prvmsg.c.
2839 * Fixed client crash if /NICK was given without arguments.
2840 Affected file lib/silcclient/command.c.
2842 * Server does not send the invite list in INVITE command back
2843 to the client if the list was not altered. Added this notion
2844 to the protocol spec as well. Affected file silcd/command.c.
2846 Fixed possible crash in INVITE command by checking the
2847 value of silc_server_get_client_route command.
2849 * Fixed the INVITE notify type handling. The arguments are now
2850 taken in correct order and client does not crash. The affected
2851 file is irssi/src/silc/core/silc-channels.c.
2853 Removed the "Inviting xxx to channel" message from the
2854 client library away and let the application handle it.
2855 Affected file lib/silcclient/command.c. Added that message
2856 to Irssi SILC client's message formats.
2858 * Fixed CMODE command crash in client. It now checks the
2859 amount of arguments correctly and does not crash. The affected
2860 file is lib/silcclient/command.c.
2862 * Do not create new channel automatically in silc_channels_join
2863 but check whether the channel by that name already exists.
2864 Affected file irssi/silc/core/silc-channels.c.
2866 * Do not send the SERVER_SIGNOFF to router if the disconnected
2867 entity was the router. Affected file silcd/server.c.
2869 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2870 SILC client as it was missing from there.
2872 Added the handling of the KICK notify to the Irssi SILC client
2873 as it was missing. Added "you have been kicked" message to
2874 Irssi SILC client's message modules formats.
2876 Added the handing of the KILL notify to the Irssi SILC client
2877 as it was missing. Added the kill message module formats
2880 The affected file is irssi/src/silc/core/silc-channels.c.
2882 * The router did not save the channel mode the server announced.
2883 Affected file silcd/packet_receive.c.
2885 * Fixed a possible crash in INFO command in server. If the
2886 server did not provide the server info it crashed. Affected
2887 file silcd/command.c.
2889 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2891 * Fixed the GETKEY command in the server to check also the
2892 global list. Otherwise the GETKEY would not work correctly
2893 in normal SILC server. Affected file silcd/command.c.
2895 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2897 * Fixed GETKEY crash, it crashed if the command did not succseed.
2899 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2901 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2902 is now real and not just an macro interface to GMP.
2904 Removed the entire GMP from the source tree and imported new
2905 NSS MPI library instead. Reason for removing GMP is that it is
2906 extremely large and compiles extremely slow. The NSS MPI
2907 is only a few files and compiles in less than 10 seconds.
2908 The speed is also about the same as GMP. The MPI is imported
2909 to lib/silcmath/mpi.
2911 If the system has GMP installed we will still use the GMP.
2912 If it is not then the NSS MPI will be compiled.
2914 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2916 * Merged a long nickname (127 characters long) crash bugfix from
2917 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2919 * Merged a freed memory reference bugfix from Irssi CVS tree.
2920 Affected file irssi/src/core/commands.c.
2922 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2924 * Added the server's public key sving and verification to the
2925 server when performing the SKE. This was missing and the
2926 remote server's (or router's) public key was accepted without
2927 checking whether we have it previously or trust it at all.
2928 Affected file silcd/protocol.c.
2930 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2932 * Check in the silc_server_timeout_remote if protocol is active
2933 and make sure that the protocol's final callback is called so
2934 that all memory if freed. Affected file silcd/server.c.
2936 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2938 * silc_server_whois_send_reply crashed the server if the nickname
2939 was 127 characters long. Affected file silcd/command.c.
2941 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2943 * Added sanity check to the silc_server_new_client. If the hostname
2944 is provided inside username then check that the provided hostname
2945 really is the same as the resolved one. If the hostname was not
2946 resolved then check it from the public key. Affected file is
2947 silcd/packet_receive.c.
2949 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2950 if the server disconnected us and the connection is not valid
2951 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2953 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2954 the library to the lib/silcutil/silcutil.[ch].
2956 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2958 * Close log file after open. Affected file
2959 lib/silcutil/silclog.c.
2961 * Check whether sock == NULL in silc_client_send_packet and return
2962 if it is. Affected file lib/silcclient/silcclient.c.
2964 * Check rec->entry == NULL in the Irssi SILC Client before
2965 sending the channel message. Affecte file is
2966 irssi/src/silc/core/silc-servers.c.
2968 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2970 * Merged a splitted window bugfix from Irssi CVS tree. The
2971 affected file is irssi/src/fe-text/textbuffer-view.c.
2973 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2974 It did not print nickname.
2976 * Improved the distributions system a bit.
2978 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2980 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2981 irssi/src/fe-text/gui-window.c.
2983 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2984 to in-active server. The affected file is
2985 irssi/src/silc/core/client_ops.c.
2987 * Resolve the client in USERS command reply if the entry does
2988 not have username resolved. The affected file is
2989 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2990 command to WHOIS command to really resolve stuff. The USERS
2991 is not used any more in any critical section so WHOIS can
2992 be used even though it might be slower than IDENTIFY.
2994 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2997 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * Changed the protocol API a bit more consistent in the
3000 lib/silccore/silcprotocol.[ch].
3002 * Changed the following headers to ROBODoc format:
3004 lib/silccore/silcpayload.h
3005 lib/silccore/silcprotocol.h
3006 lib/silccore/silcsockconn.h
3008 All core library headers are now formatted.
3010 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3012 * Fixed a bug in Irssi SILC client; do not show that you are
3013 server/router operator if you really are not. Affected file is
3014 irssi/src/silc/core/client_ops.c.
3016 * Renamed silc_command_free_payload to silc_command_payload_free.
3017 Affected file lib/silccore/silccommand.h
3019 * Added silcmath.h to include the prototoypes of various routines
3020 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3023 * Changed the following headers to ROBODoc format:
3025 lib/silccore/silcchannel.h
3026 lib/silccore/silccommand.h
3027 lib/silccore/silcid.h
3028 lib/silccore/silcidcache.h
3029 lib/silccore/silcmode.h
3030 lib/silccore/silcnotify.h
3031 lib/silccore/silcpacket.h
3032 lib/silcmath/silcmath.h
3034 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3036 * Added checking to the server code not to start the server if
3037 ciphers and stuff are not configured properly. Affected files
3038 silcd/serverconfig.[h] and silcd/server.c.
3040 * Changed the layout of the header files of the public interfaces
3041 in the SILC libraries. The new layout supports ROBODoc
3042 documentation tool (and some others) so that it is easy to create
3043 a library reference manual. All the other headers and source
3044 code must still follow the CodingStyle document. Also source
3045 code must not include these ROBODoc stuffs, only the headers.
3046 Furthermore, all public interface headers must now be named
3047 by using `silc' prefix, example: silcapi.h, silccipher.h.
3048 Some files were renamed due to this. All the other headers
3049 must not be used as public interfaces. I will update the
3050 CodingStyle document later. Changed following headers, so far:
3052 lib/silcclient/silcapi.h
3053 lib/silccore/silcauth.h
3054 lib/silccore/silcprivate.h
3055 lib/silccrypt/silcdh.h
3057 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3061 * Removed silc_client_packet_send_flush from the client library
3062 as it is not needed. Affected file lib/silcclient/client.[ch].
3064 * Added printing of message of unresolved authentication method
3065 to the Irssi SILC client. Added it to the module formats.
3066 Removed the same message from the client library.
3068 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3070 * Added new distribution feature, DISTLABEL. Every distribution
3071 can define own preprocessor label that can be used in the
3072 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3073 file distributions, acconfig.h.pre and prepare.
3075 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3077 * Added Makefile.defines_int to include the actual definitions
3078 for Makefile.defines.in. Tested the new distribution system,
3079 created distributions and tested installation.
3081 * Added AWAY message printing to the Irssi SILC client. Added
3082 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3084 * Added SCONNECT command to call the SILC's CONNECT command.
3085 Cannot use CONNECT directly since Irssi uses that internally.
3086 Affected file irssi/src/silc/core/silc-servers.c.
3088 Added ACTION local command. It is same as ME command but takes
3089 the channel as mandatory argument.
3091 Rewrote some of the Irssi's help files to suite for SILC
3094 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3096 * Added Makefile.defines[.in] that should for now on be included
3097 in all Makefile.am file in the source tree. That file includes
3098 all common compilation definitions for SILC source tree.
3100 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3102 * Minor changes to the ./prepare script to change the package
3103 name according the distribution name to the configure.in.
3105 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3107 * Created new distribution system. Added file `distributions'
3108 that defines all the distributions that can be created out of
3109 the SILC source tree. The ./prepare script now reads that
3110 file to determine how to prepare the distributions. The
3111 first argument to the ./prepare is the name of the distribution
3112 and second is the version of the distribution. If given
3113 without arguments it creates the default (toolkit) distribution
3114 with the default version (defined in ./prepare).
3116 All Makefile.am files that are subject to the distributions
3117 are now named as Makefile.am.pre. These are ./Makefile.am
3118 and lib/Makefile.am. Others may be changed later.
3120 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3122 * Added invite list, ban list, some key management and connection
3123 error message printing to module formats in the Irssi SILC client.
3125 * Added new silc_client_set_away_message to set the away message
3126 that is back to the person who sent private message. The
3127 affected file lib/silcclient/silcapi.h and the
3128 lib/silcclient/client_prvmsg.c.
3130 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3132 * Fixed the private message sending in the Irssi SILC client,
3133 added local command KEY to the Irssi SILC client.
3135 Added key management and key agreement message formats to the
3136 irssi/src/fe-common/silc/module-formats.[ch].
3138 Added USERS (alias WHO) printing, server/router operator
3139 indication and LIST command printing to the module formats.
3141 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3143 * Fixed channel joining notify handling, cumode notify handling
3144 from Irssi SILC client.
3146 * Added SILC specific module-formats to the Irssi SILC client so
3147 that SILC specific message hilighting, colors etc is possible.
3148 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3150 Added channel mode, channel user mode, actions, notices,
3151 whois and whowas printing to the the module-formats.c.
3153 * Fixed a bug in channel deletion in the server. The channel
3154 is not left to the cache even if the channel founder auth mode
3155 is set when there are no users anymore on the channel. Affected
3156 file silcd/server.c.
3158 * The silc_net_localhost now resolves the entire hostname including
3159 the domain name. Affected file lib/silcutil/silcnet.c.
3161 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3163 * Changed the ask_passphrase client operation to be ascynchronous.
3164 It has now a completion callback and a context that the
3165 application must call after it has got the passphrase from
3166 the user. Affected files lib/silcclient/silcapi.h,
3167 lib/silcclient/protocol.c, lib/silcclient/command.c and
3170 Added SilcAskPassphrase callback that the application calls
3171 to deliver the passphrase to the library.
3173 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3174 The public key verification and especially a certificate
3175 verification is asynchronous procedure.
3177 Added new SILC_SKE_STATUS_PENDING status to indicate the
3178 request is pending and a callback will be called to finalize
3181 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3182 indicate that remote end did not send its public key (or
3183 certificate), even though we require it. Added check for this
3184 condition in the SKE. This was a security bug, now fixed.
3186 Defined new SilcSKEVerifyCbCompletion callback that is called
3187 when the verification process is completed.
3189 The affected files lib/silcske/silcske_status.h and
3190 lib/silcske/silcske.[ch].
3192 * Changed the verify_public_key client operation to be async
3193 as well. Defined SilcVerifyPublicKey callback that is used to
3194 indicate the success of the public key verification process.
3196 Changed the server and client to use the new async client
3199 * Changed the Irssi SILC client's internal scheduler to be called
3200 twice as many times as it used to be. As a result the client
3201 should be a bit faster now. Affected file is
3202 irssi/src/silc/core/silc-core.c.
3204 * Added support to Irssi SILC client of asynchronous public key
3205 verification and passphrase inquiry. Affected file is
3206 irssi/src/silc/core/silc-core.c.
3208 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3210 * Do not say "You have left channel %s" in client library.
3211 Moved it to the application. Affected files are
3212 lib/silcclient/command.c and silc/client_ops.c.
3214 * Fixed silc_client_get_clients. Command context was not
3215 duplicated and was freed memory in the callback. Affected
3216 file lib/silcclient/idlist.c.
3218 * Do not say "you are now talking..." on JOIN command in the
3219 client library. The appliation must handle it.
3221 * Do not say ".. changed topic to" in command reply in the
3222 client libary. The application must handle it.
3224 * Fixed TOPIC command sending in the client library.
3226 * Fixed a memory leak in silc_client_command_free in the file
3227 lib/silcclient/command.c.
3229 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3231 * Imported a modified version of Irssi client to the source tree.
3232 The Irssi will be used to create a new client called
3233 Irssi SILC. Imported to irssi/.
3235 Added silc_core_init_finish function to the Irssi. Affected
3236 file irssi/configure.in.
3238 A lot changes in the Makefile.ams around the irssi tree.
3240 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3242 * Do not rehash if the new size is same as the old size of the
3243 hash table, in the silc_hash_table_rehash*. The affected file
3244 lib/silcutil/silchashtable.c.
3246 * Replaced hash_table_del_by_context calls from the server
3247 (when channel->user_list and client->channels) to the
3248 hash_table_del as it is sufficient and faster.
3250 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3252 * Added silc_hash_table_list, silc_hash_table_get and the
3253 SilcHashTableList structure to provide an alternative way to
3254 traverse the hash table. The affected files are
3255 lib/silcutil/silchashtable.[ch].
3257 * Changed the server's idlist routines to use the hash table
3258 routines to optimize the code.
3260 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3262 * Replaced the client entry's `channel' list and channel entry's
3263 `user_list' list to hash tables for optimized lookup. Changed
3264 the code to use the hash table interface around the code.
3265 Affected file lib/silcd/idlist.[ch].
3267 * Added `auto_rehash' boolean argument to the function
3268 silc_hash_table_alloc to indicate whether the hash table should
3269 auto-rehash when it thinks is appropriate time. It will
3270 increase the hash table size if the there is twice as much
3271 entries in the table than the size of the table, and will
3272 decrease the size if there are twice as less entries than
3273 the size of the table.
3275 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3277 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3279 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3281 * silc_idcache_purge_by_context deletes the entry now by context
3282 as it is supposed to do. Affected file lib/silccore/idcache.c.
3284 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3285 client is not anymore valid (WHOWAS givens the info) and not
3286 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3288 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3290 * Removed the `data' and `data_len' arguments from the ID Cache
3291 interfaces and added `name' argument. ID Cache does not handle
3292 anymore the binary data only a names associated with given ID.
3294 * When hashing a Client ID with silc_hash_id the entire ID is
3295 not hashed anymore, instead only the hash of the Client ID is
3296 hashed. This way we can access the Client ID from the cache
3297 with Client ID but with the hash of the ID (which is a hash of
3298 the nickname) as well without any difference in performance.
3300 Added also silc_idcache_find_by_id_one_ext to do one on one
3301 searching when we have the actual ID. Added also function
3302 silc_hash_client_id_compare. The affected files are
3303 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3305 * When hashing the name associated with a ID it is always done
3306 in lowercase. This way we can access the cache without worrying
3307 about case-sensitivity, even though, for example nicknames are
3310 * Fixed a bug in server with channel message sending. It put
3311 wrong ID type as destination ID. The affected file
3312 silcd/packet_send.c.
3314 * silc_idcache_del_by_context now deletes from all hash tables
3315 by context. Affected file lib/silccore/idcache.c.
3317 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Changed the client library to use the new ID Cache interface.
3320 Changes around the source tree.
3322 * Added silc_hash_table_rehash_ext to rehash with specific
3323 hash function. Affected file lib/silcutil/silchashtable.[ch].
3325 * Added silc_hash_string_compare to compare two strings in the
3326 hash table. Affected file lib/silcutil/silcutil.[ch].
3328 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3330 * Added new function silc_idcache_del_by_context into the
3331 lib/silccore/idcache.[ch].
3333 * Changed the server's ID list routines to use the new ID Cache
3334 interface. Changes around the source tree.
3336 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3338 * Added silc_hash_table_del[_by_context]_ext functions in to the
3339 lib/silcutil/silchashtable.[ch].
3341 Removed silc_hash_table_find_all* routines and added new
3342 silc_hash_table_find_foreach to replace them.
3344 Added silc_hash_table_replace_ext function as extended
3345 replacing function. Separated the simple hash table interface
3346 from the extended hash table interface in the file
3347 lib/silcutil/silchashtable.h.
3349 * Fixed minor bugs and changed it to use some of the new
3350 hash table functions in lib/silccore/idcache.c
3352 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3354 * Added new function silc_hash_table_find_all to return all keys
3355 in the hash table by the specified key. As the hash table is
3356 collision resistant it also makes it possible to have several
3357 duplicate keys in the hash table. This function may be used to
3358 find all of the keys from the hash.
3360 Added user_context arguments to the SilcHashFunction,
3361 SilcHashCompare and SilcHashDestructor to deliver user specified
3364 Added new fuctions silc_hash_table_find[_all]_ext to do
3365 extended lookup with specified hash and compare functions and
3366 specified user contexts.
3368 Added new function silc_hash_table_add_ext to add the key
3369 with specified hash function and user context.
3371 Added new function silc_hash_table_foreach to traverse all
3372 entrys in the hash table. Added SilcHashForeach callback
3375 Added new function silc_hash_table_del_by_context to delete
3376 the entry only if the context associated with the key matches.
3378 Affected files are lib/silcutil/silchashtable.[ch].
3380 * Removed silc_hash_[server/client/channel]_id and added just
3381 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3382 silc_hash_id_compare to compare two ID's using as the hash table
3383 comparison function. Added also silc_hash_data to hash
3384 binary data and silc_hash_data_compare to compare it.
3386 * Removed silc_idlist_find_client_by_hash as it is not needed
3387 anymore. Affected file silcd/idlist.[ch].
3389 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3390 to use internally the SilcHashTable. The new ID Cache is a lot
3391 faster than the old one. Some of the ID Cache interface was also
3392 rewritten and obsolete and stupid functions were removed.
3394 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3396 * Added entry_count field to the SilcHashTable to keep the number
3397 of the entries in the table. Implemented the function
3398 silc_hash_table_rehash. Added new function
3399 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3401 Fixed a minor bug in silc_hash_table_free.
3403 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3404 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3405 into the lib/silcutil/silcutil.[ch].
3407 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3409 * Implemented a collision resistant hash table into the
3410 lib/silcutil/silchashtable[ch]. See the header and the source
3411 for the SilcHashTable API.
3413 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Merged dotconf version 1.0.2 into lib/dotconf.
3417 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3419 * Do not compile anything in lib/silcsim/* if the SIM support
3420 is not enabled. The tree should now compile without problems
3423 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3425 * Compiled the SILC under cygwin. Compiled and tested briefly
3426 without problems. More tests needed. The SIMs didn't compile
3429 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3431 * Fixed possible crash in silc_get_username in the
3432 lib/silcutil/silcutil.c.
3434 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * Fixed a va_arg in silc/client_ops.c.
3438 * Oops, RC5 routines were named AES and caused some problems
3439 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3441 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3443 * Added new SilcIDIP structure into the lib/silccore/id.h and
3444 replaced the old `ip' fields from all SILC ID's to that type.
3445 This is a step towards IPv6 support.
3447 The silc_id_get_len takes now the ID as an extra argument.
3448 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3449 both IPv4 and IPv6 based ID's.
3451 The affected files are lib/silccore/id.[ch] and other files
3452 around the tree using these routines.
3454 * Removed the ID length arguments in server from various
3455 silc_server_send_notify_* routines -> they are not needed
3458 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3460 * Fixed memory leak in silc_encode_pem_file in the file
3461 lib/silcutil/silcutil.c.
3463 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3465 * Check minor version as well in the SKE. Affected files are
3466 silcd/protocol.c and lib/silcclient/protocol.c.
3468 * Added --identifier option to the server so that an identifier
3469 can be when creating the public key for the server. Affected
3470 file is silcd/silcd.c.
3472 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3473 lib/silccrypt/silcpkcs.c.
3475 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3477 * Register default ciphers and stuff when using -C option with
3478 the server. Affected file sildc/silcd.c.
3480 * Put back the servers public key filename format, it is better
3481 than the new one. For now, the client keys are saved with the
3482 new filename format. The affected file silc/client_ops.c.
3484 * Implemented the Cipher API for the rest of the ciphers that
3485 did not implement it or implemented it the wrong way.
3487 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3489 * Register default ciphers and stuff when using the -S option
3490 in the client. Affected file silc/silc.c. Same also when
3491 creating new key pair with -C option.
3493 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3495 * Fixed the silc_verify_public_key client operation function to
3496 save the public keys differently. The fingerprint is now
3497 used as filename and not the hostname. This way also the
3498 client keys are saved uniquely and not with hostnames. The
3499 affected file is silc/client_ops.c.
3501 * Trimmed the silc_hash_fingerprint function to remove extra
3502 whitespaces from the end of the fingerprint. The affected
3503 file is lib/silccrypt/silchash.c.
3507 * Added silc_cipher_register_default function to register all
3508 default ciphers. It can be used when configuration files
3509 does not exist and the application does not want any specific
3510 ciphers in any specific order.
3512 The SilcDList is now used as silc_cipher_list dynamically
3513 allocated cipher list. Removed the static list all together
3514 and now all ciphers must be allocated to the dynamic list.
3515 The silc_cipher_alloc routine was changed to check only the
3518 All silc_cipher_* routines that used to return int returns
3521 The affected files lib/silccrypt/silccrypt.[ch].
3523 * The same thing was done to silc_hash_* as for silc_cipher_*
3524 routines. Affected files lib/silccrypt/silchash.[ch].
3526 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3527 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3528 Added also silc_pkcs_[un]register[_default] functions.
3529 Removed the data_context from the PKCS API.
3531 * Added silc_hmac_register_default function to register default
3532 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3533 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3534 to unregister all hmacs at once.
3536 * Register the default ciphers, hash functions, PKCSs and HMACs
3537 if client's configuration file does not exist. The affected
3540 * The client did not load the hash functions from the SIM
3541 modules at all. Added support for this. Affected file is
3542 silc/clientconfig.c.
3544 * When decoding public key with silc_pkcs_public_key_decode, check
3545 the supported algorithm only if PKCS are registered. Affected
3546 file lib/silccrypt/silcpkcs.c. The same was done with the
3547 silc_pkcs_private_key_decode.
3549 * Fixed the SILC List routines to keep the list always in order.
3550 It used to change the list's order when traversing the list but
3551 not it preserves the order. Affected file lib/trq/silclist.h.
3553 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3555 * Added the client library to use the SilcSocketConnection's
3556 reference counter (by silc_socket_dup) to prevent the bug that
3557 the socket object may be freed underneath async operation.
3559 * The name resolv library checking fixes in the configure.in.pre.
3562 * Created new version of the protocol drafts for future
3563 development. The -03 drafts are the ones that will be changed
3564 in the trunk now and the -02 will remain as they are.
3566 * Send list of CUMODE notifys to the router when announcing
3567 the channel users to the router. Affected file silcd/server.c.
3568 If the router receiving channel founder CUMODE for a channel
3569 that already has channel founder it will send CUMODE notify
3570 to the sender to remove the channel founder rights from the
3571 announced client. Affected file silcd/packet_receive.c.
3573 * The CUMODE notify may now use Server ID as well as the entity
3574 who changes the mode. Updated protocool specs.
3576 * Updated INSTALL and README files.
3578 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3580 * New web pages in the http://silc.pspt.fi. The pages was
3585 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3587 * Implemented the [DenyConnectin] config section in the server.
3588 Added silc_server_config_denied_conn to check whether incoming
3589 connection is denied. Affected file silcd/serverconfig.[ch].
3591 * Do not check the ports when checking the incoming configuration
3592 data if the port is 0, meaning any. Affected file is
3593 silcd/serverconfig.c.
3595 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3597 * Fixed buffer overflow in silc_string_compare in the file
3598 lib/silcutil/silcutil.c.
3600 * Fixed double free in silc_server_command_leave in the file
3603 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * Fixed the version checking in the server. Affected file is
3608 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3610 * Fixed the configuration data fetching when accepting new
3611 connections in the server. Affected file silcd/server.c.
3613 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3615 * Added `sender_entry' argument to the function
3616 silc_server_packet_relay_to_channel so that we can check
3617 whether some destination actually belongs to the same route
3618 the sender belongs (ie, we must not resend the packet to the
3619 sender). Affected file silcd/packet_send.[ch].
3621 * Added `servername' field to the SilcClientEntry in the server
3622 to hold the name of the server where client is from. Affected
3623 file is silcd/idlist.h.
3625 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3627 * Moved the channel message encrypting in the router betwen
3628 router connections from silc_server_channel_message to the
3629 silc_server_packet_relay_to_channel since we want to check
3630 whether we have anybody channel before encrypting anything.
3631 Affected files silcd/packet_[receive/send].c.
3633 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3635 * Fixed the [AdminConnection] server config section to support
3636 multiple entries. Affected file silcd/serverconfig.c.
3638 * Added support into the server to check the validity of the
3639 incoming connection before executing any KE or authentication
3642 * The connection configuration is now saved to the KE and
3643 connection auth protocol contexts and not fetched anymore in
3644 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3646 * The local hosts listenning address and port is also resolved
3647 now when starting the server. We want to have the socket object
3648 to include the real address and port for the listener. Added
3649 new function silc_net_check_local_by_sock into the files
3650 lib/silcutil/silcnet.[ch].
3652 * Fixed a broadcast bug in server -> do not broadcast if we
3655 * Fixed a routing bug. Do not route broadcast packets ever.
3656 Broadcast packets must be processed always and not routed since
3657 they may be destined to some other host than yourself and thus
3658 would get routed without no good reason. Affected file is
3661 * Added function silc_server_config_is_primary_route to check
3662 whether primary router connection has been configured (a router
3663 configuration that we are initiating). If there is not, we
3664 will assume that there is only two routers in the SILC network
3665 and we will use the incoming router connection as our primary
3666 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3668 * Changed the order of the broadcasting. Broadcast _after_ the
3669 packet has been processed not before. Affected file is
3672 * Fixed a [ClientConnection] parsing bug. The port was never
3673 parsed correctly thus resulting to port 0. Affected file
3674 silcd/serverconfig.c.
3676 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3677 argument and did not set the broadcast packet flag. Affected
3678 file silcd/packet_send.c. Fixed same bug in the function
3679 silc_server_send_notify as well.
3681 * If we receive NEW_ID packet for our own ID in the server, ignore
3684 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3688 * Removed the nickname from the Private Message Payload.
3689 Updated the code and the protocol specs.
3691 * Updated protocol specs for submitting to the IETF.
3693 * Tweaked the Random Number Generator a bit. Affected file
3694 lib/silccrypt/silcrng.c. Exported a new function
3695 silc_rng_[global]_add_noise which can be used to add more
3698 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3700 * Do not parse packets with different timeout when protocol
3701 is active -> may cause problem with rekey. Affected file
3704 * When server receives signoff notify it must not create
3705 new channel key if the client is on any channels since the
3706 sender of the signoff notify will create it.
3708 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3710 * Added printing of error messages during SKE protocol from the
3711 failure packet sent by server during SKE. Affected file
3714 * Removed the client's failure_callback handling with timeout
3715 and handle it immediately when received.
3717 * The SKE library returned wrong type in SUCCESS and FAILURE
3718 packets. They must be 32 bit MSB not 16 bit MSB.
3720 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * Ok, rewrote the logic of the re-key and now it seems to work.
3723 I tested it on high traffic with frequent re-keys without
3724 problems. Added hmac_receive (and renamed hmac to hmac_send)
3725 in SilcClientConnection in lib/silcclient/client.h and
3726 in SilcIDListData in silcd/idlist.h. Also, removed the
3727 SilcPacketParserContext's cipher and hmac fields as they are
3728 not needed anymore and actually caused some problems when
3729 the ciphers and hmac's changed underneath the packet parser.
3731 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3733 * If re-key protocol is active then process the incoming packets
3734 synchronously since we must assure that icoming packets encrypted
3735 with the old key is processed before the new keys is set to
3736 use. This is true other packets than for REKEY packets.
3737 Affected file silcd/server.c. The same was done to client library
3738 as well, affected file lib/silcclient/client.c.
3740 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3742 * Fixed bug in client and server to accept the force send if
3743 the packet is send from silc_[server/client]_packet_process
3744 function. Otherwise the packets are never delivered, oops.
3746 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3748 * Disable force sending of packets when REKEY protocol is active.
3749 We must assure that no packet is sent directly when rekey is
3750 performed. All packets must be sent through packet queue.
3751 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3752 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3753 function is silc_[server/client]_packet_send_real to check
3756 * Replaced the SIM paths from example config files to
3757 /usr/local/modules. Also, make install creates now
3758 /usr/local/silc/logs directory to hold all the SILC server
3761 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Made the configure.in.pre work on Solaris. Patch by salo.
3765 * Made all ciphers compatible with non-x86 machines. Defined
3766 CBC mode macros into lib/silccrypt/ciphers_def.h.
3768 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3770 * Fixed the make install.
3772 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3774 * When MAC computation fails the silc_packet_decrypt returned 0
3775 even though it was supposed to return -1. Fixed this. The
3776 affected file is lib/silccore/silcpacket.c.
3778 * Do not replace the config files in /etc/silc (in make install)
3779 if they already exist. Affected file ./Makefile.am.
3781 * Do not send re-key packets immediately but through packet queue.
3782 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3784 * Changed silc_net_check_host_by_sock to return FALSE if the
3785 IP/DNS could not be resolved. Though, it returns the IP address
3786 now even if it could not resolve it (but returns also FALSE).
3787 Affected file lib/silcutil/silcnet.[ch].
3789 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3791 * Added silc_pkcs_decode_identifier to decode the public key's
3792 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3793 Added also silc_pkcs_free_identifier. Added also new context
3794 SilcPublicKeyIdentifier.
3796 * Added -S option to the silc client. It is used to dump the
3797 contents of the specified public key file.
3799 * Changed the PKCS api to return the public key length when
3800 setting the public key.
3802 * Fixed a fatal bug in the public and private key file loading.
3803 Affected file lib/silccrypt/silcpkcs.c.
3805 * Execute the packet parsing for client with zero (0) timeout
3806 if the protocol is active. Affected file silcd/server.c.
3808 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3810 * Made the key generation options to the silcd program. Added
3811 -C option, equivalent to client's option.
3813 * Added new [ServerKeys] config section to the server. It
3814 configures the server's public and private key.
3816 * Defined generic Public Key Payload into the protocol
3817 specification to send specific type of public keys and
3820 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3821 public key or certificate.
3823 * Implemented the GETKEY command to the server and to the
3824 client library and on user interface.
3826 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3828 * Made preliminary `make install' work.
3830 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3832 * Added SilcServerRekey context into silcd/idlist.h.
3834 * Added the PFS support as defined in the specification to the
3835 SKE protocol. Affected files lib/silcske/*.c.
3837 * Added `ske_group' field to the SilcServerRekey context to hold
3838 the number of the SKE group that is used with PFS in re-key.
3839 Affected file silcd/idlist.h.
3841 * Added PFS re-key support to the server. Affected file is
3844 * Added silc_protocol_cancel to cancel execution of the next
3845 state of the protocol. Affected file is
3846 lib/silccore/silcprotocol.[ch].
3848 * Added the re-key support with and without PFS to the client
3849 library. Re-key is performed once in an hour, by default.
3851 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3852 Added silc_client_rekey_callback and silc_client_rekey_final.
3853 Affected files are lib/silcclient/protocol.[ch] and
3854 lib/silcclient/client.[ch].
3856 * Removed the `hmac_key' and `hmac_key_len' fields from the
3857 SilcClientConnection structure; not needed. Affected file is
3858 lib/silcclient/client.h.
3862 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Do not ask whether user wants to use the negotiated private key
3865 for private messages, just use it. Affected file is
3866 silc/local_command.c.
3868 * Added `send_enc_key' and `enc_key_len' fields to the
3869 SilcIDListData structure since they are needed in the re-key
3870 phase. Affected file is silcd/idlist.[ch].
3872 * Implemented the simple re-key protocol into the server.
3873 Affected files silcd/server.c and silcd/protocol.[ch]. The
3874 re-key will be performed once in an hour, by default.
3876 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3877 Added silc_server_rekey, silc_server_rekey_callback and
3878 silc_server_rekey_final.
3880 * Removed Tunneled flag from the protocol. Updated the code
3881 and the specifications.
3883 * Adde `pfs' field to the SilcIDListData to indicate whether
3884 the PFS is to be performed in the re-key. Affected file is
3887 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3889 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3890 int64 of at least the xintXX size. If void * is less that 4
3891 bytes uint32 * will be used. Defined bool as boolean.
3893 * Changed _ALL_ unsigned long and unsigned int to uint32,
3894 unsgined short to uint16 in the source tree.
3896 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3897 not handle clients that has entry->data.registered == FALSE.
3898 They are not in the network anymore. Affected file is
3901 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3903 * Implemented the sending of the SERVER_SIGNOFF notify in the
3904 server. Affected file is silcd/server.c.
3906 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3907 Added also silc_notify_payload_encode_args into the
3908 lib/silccore/silcnotify.[ch].
3910 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3911 Affected file silcd/packet_receive.c.
3913 * Implemented the SERVER_SIGNOFF notify handling in the client
3914 library. Affected file lib/silcclient/client_notify.c. Also,
3915 implemnted the printing of the SERVER_SIGNOFF info to the
3916 application. Affected file silc/client_ops.c.
3918 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3919 if the deleting was successful. Affected file silcd/idlist.[ch].
3921 * Added support for public key authentication in the connection
3922 authentication protocol in the client library. Affected file
3923 lib/silcclient/protocol.c.
3925 * Changed the server's silc_idlist_get_clients_by_* interface
3926 to support already allocated array so that new entries may be
3927 added to pre-allocated array. Affected file silcd/idlist.[ch].
3928 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3929 and command replies.
3931 * All command reply functions in the server now calls the
3932 pending command callback even if error occured. This way the
3933 error will be delivered to the client as well. Affected files
3934 silcd/command.c and silcd/command_reply.c.
3936 * Fixed INFO command to return local server's info if no server
3937 was provided. Affected file lib/silcclient/command.c.
3939 * Removed RESTART command for good. Updated the code and the
3942 * Rewrote parts of the task system. It is a bit simpler now.
3943 Removed unsued task priorities. The affected files are
3944 lib/silcutil/silctask.[ch].
3946 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Moved the USERS printing from the library to the application.
3949 Affected files lib/silcclient/command.c and silc/client_ops.c.
3951 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3955 * Added channel key re-key support. The re-key is perfomed
3956 only by the router and is done once in an hour. Added `rekey'
3957 field to the SilcChannelEntry in the server. Affected files
3958 silcd/server.c and silcd/idlist.h.
3960 * Added silc_task_unregister_by_context into the file
3961 lib/silcutil/silctask.[ch].
3963 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3965 * Added SILC_UMODE_GONE mode to indicate when the client is not
3966 present in the SILC network. Added also support to the local
3967 command AWAY that will set this mode. Added support of showing
3968 "xxx is gone" in WHOIS command. The USERS command shows the
3969 gone status as well.
3971 * Fixed setting server and router operator privileges in the
3972 server's UMODE command. Affected file silcd/command.c.
3974 * Merged the SKE KE1 and KE2 payloads into one payload. The
3975 new KE payload is equivalent to the old KE2 payload.
3977 Cleaned up the SKE Start Payload parsing. It now uses the
3978 simple buffer unformatting to do the parsing. A lot faster
3981 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3982 to the SKE that is used to indicate whether both of the SKE
3983 parties should perform authentication. By default only the
3984 responder performs authentication. By setting this flag also
3985 the initiator must do authentication. By default it is unset
3986 since in normal SKE case, client to server connection, only
3987 the responder should do authentication. When doing SKE between
3988 two clients both should perform authentication. Updated the
3989 code and the protocol specs.
3991 * A little fix to IDENTIFY command in the server. Search the
3992 client first by hash not nickname. Affected file is
3995 * Fixed the silc_client_close_connection to support closing
3996 the client to client connections wihtout deleting too much
3997 data. Affected file lib/silcclient/client.c.
3999 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4000 are received if protocol used to be active but is not anymore
4001 the application would crash due to NULL pointer dereference.
4002 Affected files silcd/server.c and lib/silcclient/client.c.
4004 * Added `hash' field to the SilcClientConnection to include
4005 the hash function negotiated in the SKE protocol.
4007 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4008 to set the channel founder authentication data. A client can
4009 claim the founder rights later by providing the authentication
4010 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4011 This way the channel founder can regain the channel founder
4012 privileges even it is left the channel. This works only on
4013 local server and the client must be connected to the same
4014 server to be able to regain the founder rights. Updated the
4015 protocol specs accordingly.
4017 Added support to the CMODE command in the client to set the
4018 founder auth data. Read the README to see how to set it.
4020 Added support to the CUMODE command to claim the founder
4021 rights. Read the README to see how to do it.
4023 Added support for the founder authentication to the Channel
4024 Entry in the server. Affected file silcd/idlist.h.
4026 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4027 server's CMODE command. Affected file silcd/command.c.
4029 * Added the following new functions into lib/silccore/silcauth.[ch]:
4030 silc_auth_get_method and silc_auth_get_data.
4032 * The server now saves the remote hosts public key to the
4033 SilcIDListData pointer. Affected file silcd/protocol.c.
4035 * The normal server now does not remove the channel entry from
4036 the cache if the founder authentication data is set. It used
4037 to remove it if the founder was the last one on the channel on
4038 the server and left the channel. The auth data is saved and
4039 if the channel is re-joined later the old entry is used with
4040 the old auth data. Affected files silcd/command_reply.c and
4043 * Removed the `pkcs' field from the SilcIDListData structure
4044 in the server; it is not used. Affected file silcd/idlist.h.
4046 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Fixed packet processing on slow links. Partial packets were
4049 never re-processed because the incoming data buffer was cleared
4050 by the application. Application must not directly clear the
4051 sock->inbuf, the packet processing routines handle it. Fixed
4052 this in client library and in server.
4054 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4056 * Fixed the WHOIS and IDENTIFY send reply function to really
4057 check whether to send list or just one entry. Affected file
4060 * Cleaned up the LEAVE command's channel key distribution. The
4061 affected file silcd/command.c.
4063 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4064 can enforce the channel mode as well. In that case the ID
4065 includes the ID of the server. The code now enforces the
4066 mode change if the router have different mode than the server.
4068 * The notify client operation with CMODE_CHANGE notify can now
4069 return NULL client_entry pointer if the CMODE was not changed
4070 by client. Application must check for this.
4072 * Added <Server ID> argument to INFO command to support server
4073 info fetching by Server ID.
4075 * Added silc_server_announce_get_channel_users to get assembled
4076 packets of channel users of the specified channel. Affected
4077 file silcd/server.[ch].
4079 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4080 was freed underneath the ID Cache.
4082 * Re-announce clients when the server received CHANNEL_CHANGE
4083 notify from the router. Affected file silcd/packet_send.c.
4085 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4087 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4088 crashed since it did not handle the fact that there is no cipher
4089 called "3" and didn't check the error condition. Now fixed.
4091 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4092 flag. It can be used to send message requests.
4094 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4096 * Implemented the RESTART command in the client.
4098 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4099 notice type messages. Added notice printing to the user
4102 * The channel keys are not re-generated if the channel's mode
4103 is PRIVKEY, ie private key on the channel exists. Affected
4104 files silcd/server.c and silcd/command.c.
4106 * Fixed a little bug in channel message delivery when channel
4107 private keys are set in the server. Affected file is
4108 silcd/packet_send.c.
4110 * Changed the setting on channel->on_channel = TRUE from the
4111 silc_client_save_channel_key to the JOIN command reply. The
4112 key payload is not received if the private channel key is set.
4113 Affected file lib/silcclient/command_reply.c and the
4114 lib/silcclient/client_channel.c.
4116 * When the CMODE_CHANGE notify is sent and the channel private
4117 key mode is removed the channel key must be re-generated in
4118 other cells as well. Added this support for the router in the
4119 silcd/packet_receive.c.
4121 * Added new local command NOTICE to send notice message on
4122 channel. Affected file silc/local_command.[ch].
4124 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4126 * Added new local command ME to the client. It is used to send
4127 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4128 some action. Affected file silc/local_command.[ch].
4130 * Changed channel_message and private_message client operations
4131 to deliver the message flags to the application. Added also
4132 the `flags' arguments to the silc_client_send_channel_message
4133 and silc_client_send_private_message functions. Affected file
4136 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Redefined the Private Message Payload to support private message
4139 keys and to support the new private message flags. Updated
4140 the protocol specs. Flags makes it possible to have for example
4141 CTCP style messages.
4143 * Added new type SilcPrivateMessagePayload and defined an API
4144 for it in the lib/silcclient/silcprivate.[ch].
4146 * Tested private message private keys successfully. Tested the
4147 private message key set, unset and list commands with the new
4150 * Redefined the Channel Message Payload to include the channel
4151 message flags (equal with private message flags) to support
4152 for example CTCP style messages.
4154 * Defined some of the message (for channel and private message)
4155 flags. Updated the protocol specs and added the flags to the
4156 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4158 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4160 * Added SilcKeyAgreementStatus type to the key agreement routines
4161 to indicate the current status and error if one occured.
4162 The status types are defined in the lib/silcclient/silcapi.h.
4164 * Added new local command KEY that is used to set and unset private
4165 keys for channels, set and unset private keys for private messages
4166 with remote clients and to send key agreement requests and
4167 negotiate the key agreement protocol with remote client. The
4168 key agreement is supported only to negotiate private message keys,
4169 it currently cannot be used to negotiate private keys for channels,
4170 as it is not convenient for that purpose.
4172 * Fixed a minor pending callback setting bug in the function
4173 silc_client_get_client_by_id_resolve, now the function works.
4174 Affected file lib/silcclient/idlist.c.
4176 * Added function silc_net_get_local_port to get local bound
4177 port by socket. Added to lib/silcutil/silcnet.[ch].
4179 * Added `sockets' and `sockets_count' fields to the SilcClient
4180 object. They hold the sockets of the listenning sockets in
4181 the client. Listenning sockets may be for example the key
4182 agreement server. Affected file lib/silcclient/client.[ch].
4183 Added functions the silc_client_add_socket and the
4184 silc_client_del_socket. They are exported to the application
4187 * Added ~./silc/clientkeys to support other client's public keys.
4189 * Renamed verify_server_key client operation to verify_public_key
4190 and added one argument to indicate the type of the connection
4191 (server, client etc.).
4193 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4195 * Added silc_server_connection_auth_request to handle the
4196 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4197 silcd/packet_receive.[ch].
4199 * Added silc_server_send_connection_auth_request into the
4200 silcd/packet_send.c to send the connection auth request packet.
4202 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4205 * Fixed the public key authentication in responder side in the
4206 server. The `auth_data' pointer includes the SilcPublicKey
4207 not the path to the public key. Affected file silcd/protocol.c.
4209 * Implemented the public key authentication in the initiator side
4210 in the server. Affected file silcd/protocol.c.
4212 * Removed the [RedirectClient] config section from the server
4213 configuration. Is not needed and I don't want to implement it.
4215 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Cleaned up the CMODE command in the server. It now works
4218 correctly and supports all the modes defined in the protocol.
4219 Affected file is silcd/command.c.
4221 * Added `hmac_name' field to the SilcChannelEntry in the server
4222 to hold the default HMAC of the channel. It can be set when
4223 creating the channel (with JOIN command). Affected files
4226 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4227 type to indicate the change of the current cipher and hmac
4228 on the channel. Client can safely ignore the <cipher> argument
4229 (if it chooses to do so) since the CHANNEL_KEY packet will
4230 force the channel key change anyway. The <hmac> argument is
4231 important since the client is responsible of setting the new
4232 HMAC and the hmac key into use.
4234 * Fixed the CMODE command in the client library as well.
4236 * Tested CMODE command in router environment successfully.
4238 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4240 * Show the version of the remote client (or server) when connecting
4241 to the server. It is logged to the log file. Affected file
4242 is silcd/protocol.c.
4244 * Fixed the KILLED notify handling in the client library. The
4245 client must be removed from all channels when receiving the
4248 Also, do not remove the client entry when giving the KILL
4249 command but when the KILLED notify is received.
4251 * Removed silc_idlist_find_client_by_nickname from the server.
4252 Not needed anymore. Affected files silcd/idlist.[ch].
4254 * Implemented the CHANNEL_CHANGE notify type handling to the
4255 server. Affected file silcd/server.c.
4259 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4261 * Added silc_server_send_notify_invite to send the INVITE
4262 notify between routers.
4264 * Implemented the INVITE command correctly to the server.
4266 * Implemented the INVITE notify type handling in the server.
4268 * Implemented the INVITE command to the client library and on the
4271 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4273 * Added function silc_server_get_client_resolve to find the
4274 client entry by ID from all ID lists and then resolve it
4275 (using WHOIS) if it cannot be found. Affected file is
4278 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4280 * Implemented the BAN command to the client library.
4282 * The JOIN command in the server now checks the invite list
4285 * Changed the silc_command_reply_payload_encode_va and the
4286 silc_command_payload_encode_va to support that if argument is
4287 NULL it ignores and checks the next argument. Affected file
4288 lib/silccore/silccommand.c.
4290 * Added silc_server_send_notify_ban to send the BAN notify
4291 type between routers.
4293 * Chaned the silc_notify_payload_encode to support that if
4294 argument is NULL it ignores and checks the next argument.
4295 Affected file lib/silccore/silcnotify.c.
4297 * Tested ban lists in router environment successfully.
4299 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4301 * Implemented BAN command to the server, in silcd/command.[ch].
4303 * Removed the BAN and INVITE_LIST modes from the CMODE command
4306 * Added function silc_string_match to regex match two strings.
4307 Affected files lib/silcutil/silcutil.[ch].
4309 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Redefined parts of the SilcChannelEntry in the server to support
4312 the new ban and invite lists.
4314 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4316 * Redefined the INVITE command. The same command can be used to
4317 invite individuals to the channel but also to manage the invite
4318 list of the channel (to add to and remove from the invite list).
4319 Updated the protocol specs.
4321 * Added new command SILC_COMMAND_BAN that can be used to manage
4322 the ban list of the channel. Updated the protocol specs.
4324 * Removed the channel modes: the SILC_CMODE_BAN and the
4325 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4326 in the CMODE command. The equivalent features are now available
4327 using INVITE and BAN commands. Updated the protocol specs.
4329 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4330 in the network about change in the current ban list. The notify
4331 type is not used by the client.
4333 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4334 support the invite lists.
4336 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4338 * Added new function silc_string_regexify that converts string
4339 including wildcard characters into regex string that can
4340 be used by the GNU regex library. Added into the file
4341 lib/silcutil/silcutil.[ch].
4343 Added silc_string_regex_combine to combine to regex strings
4344 into one so that they can be used as one regex string by
4345 the GNU regex library. Added into the file
4346 lib/silcutil/silcutil.[ch].
4348 Added silc_string_regex_match to match two strings. It returns
4349 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4351 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * Imported GNU regex to the soruce tree into lib/contrib.
4354 Fixed some compiler warning from the regex.c.
4356 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4358 * Fixed MOTD command in the server to work in router environment.
4360 * Fixed the MOTD command in the client library to support
4361 the server argument in the command.
4363 * Added `nickname_len' argument to the silc_idlist_add_client
4364 in the server, as the `nickname' argument may be binary data
4367 * Added silc_idlist_get_channels to return all channels from
4370 * Implemented LIST command to the server. Affected file is
4373 * Implemented the LIST command to the client library and on the
4376 * Added [<user count>] argument to the LIST command reply.
4377 With private channels the user count is not shown.
4379 * Updated TODO and README.
4381 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * The client entry's data.registered must be TRUE even with
4384 global client entry on global client list. The data.registered
4385 is used to check whether the client is anymore in the network,
4386 for example with WHOWAS command so it must be valid.
4388 * Fixed the WHOWAS command in the server. It now actually works
4389 in router environment. Added function into silcd/command_reply.c
4390 silc_server_command_reply_whowas_save.
4392 * Added silc_idlist_purge function to the silcd/idlist.c
4393 to periodically purge the ID Cache.
4395 * Fixed INFO command in the server. It works now in router
4396 environment. Added <server name> argument to the INFO command
4397 reply. Updated the protocol specs.
4399 * Fixed minor bug in silc_idcache_purge to not purge if the
4400 expire value is zero.
4402 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4403 they were buggy because of the WHOWAS information.
4405 * Fixed local command MSG to handle the async resolving of
4406 the remote client properly. It used to fail the first MSG.
4407 Affected file silc/local_command.c.
4409 * Added `data_len' field to SilcIDCache context.
4411 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4413 * Update TODO. Todo in commands in the server.
4415 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4417 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4418 used by routers as broadcast packet to inform other routers
4419 about the changed user mode.
4421 Implemented the notify handling in the server. Affected file is
4422 silcd/packet_receive.c. Added the function
4423 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4425 * Added new generic Channel Payload and deprecated the New Channel
4426 Payload. The New Channel Payload is now the generic Channel
4429 * Added new argument `mode' to the silc_server_send_new_channel
4430 as it is required in the Channel Payload now.
4432 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4433 and created a new and real SilChannelPayload to represent the
4434 new generic Channel Payload. Implemented the encode/decode
4435 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4437 * Added silc_server_get_client_channel_list to return the list
4438 of channels the client has joined for WHOIS command reply.
4439 Affected file silcd/server.[ch].
4441 * Implemented the channel list sending in the WHOIS command reply
4442 in server and in the client.
4444 Implemented the channel list displaying on the user interface
4445 as well. Affected file silc/client_ops.c.
4447 * Added silc_channel_payload_parse_list to parse list of Channel
4448 Payloads. It returns SilcDList list of SilcChannelPayloads.
4449 Client for example can use this function to parse the list of
4450 channels it receives in the WHOIS command reply. The caller
4451 must free the list by calling silc_channel_payload_list_free.
4452 Affected files lib/silccore/silcchannel.[ch].
4454 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4456 * Added one new argument <user mode> to the WHOIS command reply
4457 to return the mode of the user in SILC. Updated the protocol
4460 Implemented it to the server and client.
4462 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * Fixed the mode printing on the user interface on joining.
4465 Affected file silc/client_ops.c.
4467 * Implemented the UMODE command and user modes in general to the
4468 client library and to the user interface.
4470 * Implemented the UMODE command to the server.
4472 * The server now sends UNKNOWN_COMMAND error status if client sends
4473 unknown command. Affected file silcd/command.c.
4475 * All server commands now handle the command identifier the right
4476 way when sending the command reply to the client. The client can
4477 use to identify the command replies with the identifier.
4479 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Added silc_server_get_client_route to resolve the route to
4482 the client indicated by the client ID. Affected file is
4485 * Added silc_server_relay_packet as general function to relay
4486 packet to arbitrary destination. This deprecates functions
4487 like _send_private_message_key, _relay_notify etc. Affected
4488 file is silcd/packet_send.[ch].
4490 Removed silc_server_send_key_agreement,
4491 silc_server_send_private_message_key and
4492 silc_server_packet_relay_notify functions from the file
4493 silcd/packet_send.[ch].
4497 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4498 server. Affected file silcd/packet_receive.[ch].
4500 * Implemented the KILL command to the client. Implemented the
4501 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4502 Affected files lib/silcclient/command[_reply].c and
4503 lib/silcclient/client_notify.c. Implemented the KILL notify
4504 printing in the user inteface.
4506 * Fixed a lot silc_parse_nick memory leaks from the client
4507 library in the file lib/silcclient/command.c.
4509 * Changed the silc_server_send_notify_on_channels's `sender'
4510 argument from SilcSocketConnection to SilcClientEntry to
4511 check the sender as entry and not as connection object and not
4512 to send to the client provided as argument. The affected file
4513 is silcd/packet_send.[ch].
4515 * The notify packets that are destined directly to the client used
4516 to not to be processed by the server. Now changed that and the
4517 server processes all notify packets. After relaying the packet
4518 to the client the notify packet is processed in the server.
4520 * The silc_server_free_client_data now checks whether there is
4521 pending outgoing traffic for the client and purges the data to
4522 the network before removing the client entry.
4524 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4526 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4527 an client is killed from the SILC Network. Updated the protocol
4530 Added new function silc_server_send_notify_killed to the
4531 silcd/packet_send.[ch].
4533 * Added function silc_server_packet_relay_notify to relay notify
4534 packets that are destined directly to a client. In this case
4535 the server does not process the notify packets but merely relays
4536 it to the client. Affected file silcd/packet_send.[ch].
4538 Added also silc_server_packet_process_relay_notify to check
4539 whereto relay the notify. Affected file is
4540 silcd/packet_receive.[ch].
4542 * Implemented the KILL command to the server.
4546 * Added the backup schema desgined last fall to the protocol
4547 specs for everyone to see. The specification is in the
4548 *-spec-xx.txt draft and the packet type definitions for the
4549 backup routers is in *-pp-xx.txt draft. Thusly, added also
4550 new packet type SILC_PACKET_CELL_ROUTERS.
4552 * A big security problem in the implementation discovered. The
4553 signoff of an client did not cause new channel key generation
4554 which it of course should've done. The channel keys must be
4555 always re-generated when client leaves (or signoffs) the channel.
4556 The silc_server_remove_from_channels funtion now handles
4557 the channel key re-generation.
4559 * Added `sender' argument to the silc_server_send_notify_on_channels
4560 to not to send the client provided as argument. Affected file
4561 silcd/packet_send.[ch].
4563 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4565 * Implemented OPER and SILCOPER commands into the server and
4568 * Added silc_auth_verify and silc_auth_verify_data to verify
4569 the authentication directly from the authentication payload.
4570 It supports verifying both passphrase and public key based
4571 authentication. Affected file lib/silccore/silcauth.[ch].
4573 * Added `hash' field to the SilcIDListData structure. It is the
4574 hash negotiated in the SKE protocol. Affected file is
4577 * Slight redesigning of the SilcAuthPayload handling routines.
4578 Do not send SilcPKCS but SilcPublicKey as argument.
4580 * Implemented the public key authentication support to the
4581 serverconfig. The public key is loaded from the provided path
4582 and saved as authentication data to void * pointer. Thus,
4583 changed the unsigned char *auth_data to void *auth_data;
4585 * Fixed SHUTDOWN command to send the reply before the server
4586 is shutdown. :) Affected file silcd/command.c.
4588 * Fixed fatal bug in CONNECT command. The hostname was invalid
4589 memory and server crashed. Affected file silcd/command.c.
4591 * Fixed fatal bug in CLOSE command. The server_entry became
4592 invalid but was referenced later in the command. Affected file
4595 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Fixed fatal bug in failure packet handling. Server ignored
4598 the failure and thus crashed when it came.
4602 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4604 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4605 that the command may be executed only once in (about) 2 seconds.
4606 The old SILC_CF_LAG flag is same but allows command bursts up
4607 to five before limiting.
4609 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4610 server code. Various commands now includes the CF_LAG_STRICT
4611 flag to disallow any kind of miss-use of the command.
4613 * Fixed the silc_buffer_unformat to not to allocate any data
4614 if the length of the data is zero. It used to allocate the
4615 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4617 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4619 * Changed the format of AdminConnection configuration section
4620 in the server. Added username of the admin to the format.
4621 Affected files silcd/serverconfig.[ch].
4623 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4624 to return admin configuration data by host, username and/or
4627 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4629 * Implemented WHOWAS command to the server. Added the functions:
4631 silc_server_command_whowas_parse,
4632 silc_server_command_whowas_send_reply,
4633 silc_server_command_whowas_from_client and
4634 silc_server_command_whowas_from_server
4636 * Added <Client ID> argument to the WHOWAS command reply. Updated
4637 the protocol specs accordingly.
4639 * Implemented WHOWAS command and command_reply to the client
4642 Implemented the WHOWAS printing on the user interface.
4644 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4646 * Added new argument to the WHOWAS command reply, the real name.
4647 It is an optional argument. Updated the protocol specs.
4649 * Added SilcIDCacheDestructor callback that is registered when
4650 the SilcIDCache is allocated. The callback is called when
4651 an cache entry in the ID Cache expires, or is purged from the
4652 cache. Added into lib/silccore/idcache.[ch].
4654 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4655 to destruct the client entries when the cache entry expires.
4656 Other ID Cache's in server and in the client library ignores
4659 * If the ID Cache entry's `expire' field is zero then the entry
4660 never expires. Added boolean `expire' argument to the
4661 silc_idcache_add function in the lib/silccore/idcache.[ch].
4662 If it is TRUE the default expiry value is used.
4664 * Added silc_server_free_client_data_timeout that is registered
4665 when client disconnects. By default for 5 minutes we preserve
4666 the client entry for history - for WHOWAS command.
4668 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4670 * Added support to the server to enforce that commands are not
4671 executed more than once in 2 seconds. If server receives
4672 commands from client more frequently, timeout is registered
4673 to process the commands. Affected file silcd/command.c.
4674 Added new function silc_server_command_process_timeout.
4676 * Changed NICK_NOTIFY handling in client library to check that
4677 if the client's nickname was changed, so there is no need to
4678 resolve anything from the server.
4680 * Removed error printing from the WHOIS and IDENTIFY commands.
4681 If error occurs then it is ignored silently in the client library.
4682 The application, however, may map the received error to
4683 human readable error string. The application currently maps
4684 the NO_SUCH_NICKNAME error to string.
4686 * Made the command status message public to the application. Moved
4687 them from lib/silcclient/command_reply.c to
4688 lib/silcclient/command_reply.h. The application can map the
4689 received command status to the string with the
4690 silc_client_command_status_message function.
4692 * Added check to the server to check that client's ID is same
4693 as the Source ID in the packet the client sent. They must
4696 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4698 * Added dist-bzip hook to the Makefile.am to make bzip2
4699 compressed distributions.
4701 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4703 * Server now enforces the maximum length for the nickname and
4704 the channel as protocol specification dictates. 128 bytes for
4705 nickname and 256 bytes for channel name.
4707 * Moved the WHOIS printing to the application. The client libary
4708 does not print out the WHOIS information anymore, the application
4709 must do it. Renamed silc_client_command_reply_whois_print to
4710 the silc_client_command_reply_whois_save.
4712 The client's idle time is also sent to the application now, and
4713 the idle is shown on screen.
4715 * Added silc_client_command_reply_identify_save to save the
4716 received IDENTIFY entries.
4718 * Do not check for channel private keys in message sending and
4719 reception if the channel does not have the PRIVKEY mode set.
4720 Affected file lib/silclient/client_channel.c.
4722 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4724 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4725 just surfaced after chaning the JOIN procedure.
4727 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4729 * Added silc_client_get_clients_by_list to get client entries
4730 from Client ID list, that is returned for example by JOIN
4731 and USERS command replies. The application should use this
4732 function for example when JOIN command reply is received to
4733 resolve the clients already on the channel (library does not
4734 do that anymore as USERS command reply is not used in the JOIN
4735 procedure anymore). Affected files lib/silcclient/silcapi.h and
4736 lib/silcclient/idlist.c.
4738 * JOIN command reply and USERS command reply returns now SilcBuffer
4739 pointers instead of unsigned char pointers when returning
4740 the client list and mode list.
4742 * Added <Client ID> argument to the JOIN command reply, mainly
4743 for the server to identify for which client the command was
4744 originally sent. Updated protocol specs accordingly.
4746 * Added SilcDlist private_key pointer to the SilcChannelEntry
4747 in the client to support the channel private keys. Affected
4748 file is lib/silcclient/idlist.h.
4750 * Added SilcChannelPrivateKey argument to the function
4751 silc_client_send_channel_message so that application can choose
4752 to use specific private ke if it wants to. If it is not provided,
4753 the normal channel key is used, unless private keys are set.
4754 In this case the first (key that was added first) is used
4755 as the encryption key.
4757 * Implemented the support for channel private key handling.
4758 Implemented the following functions:
4760 silc_client_add_channel_private_key,
4761 silc_client_del_channel_private_keys,
4762 silc_client_del_channel_private_key,
4763 silc_client_list_channel_private_keys and
4764 silc_client_free_channel_private_keys
4766 Affected file lib/silcclient/client_channel.c.
4768 * Added the support for the private keys in the channel message
4769 sending and encryption and in the message reception and
4770 decryption. Affected funtions are
4771 silc_client_send_channel_message and silc_client_channel_message.
4773 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4775 * Added SKE's key verify callback to the client library's
4776 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4778 * Removed the statement that server (or router) must send USERS
4779 command reply when joining to the channel so that the client
4780 knows who are on the channel. Instead, the client list and
4781 client's mode list is now sent in the JOIN command reply to the
4782 client who joined channel. This is better solution.
4784 * Added function silc_server_get_users_on_channel and function
4785 silc_server_save_users_on_channel to the silcd/server.[ch].
4787 * Removed function silc_server_command_send_users from the
4790 * Do not show topic on the client library anymore. The topic is
4791 sent in the command reply notify to the application and the
4792 application must show the topic now.
4794 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4796 * Added client searching by nickname hash into the IDENTIFY and
4797 WHOIS commands in the server as they were clearly missing from
4798 them. Affected file is silcd/command.c.
4800 * Fixed a bug in private message receiving in the client library.
4801 The remote ID was freed and it wasn't supposed, now it is
4804 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4806 * Minor fix to the channel payload; allocate the data area, as it
4807 needs to be of specific length.
4809 * If the key agreement port is zero then the operating
4810 system will define the bound port. Affected files are
4811 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4813 * Added new function silc_channel_payload_decrypt into the file
4814 lib/silccore/silcchannel.[ch].
4816 * Moved the channel message etc, check from silc_packet_decrypt
4817 to applications. The library calls now a generic
4818 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4819 when the packet is either normal or special. This was done to
4820 allow more wide range of checking that was not allowed when
4821 the code was in library. Now applications can do virtually any
4822 checks to the packet and return to the library the decision how
4823 the packet should be processed. Affected files are
4824 lib/silccore/silcpacket.[ch].
4826 Added silc_server_packet_decrypt_check to the server and
4827 silc_client_packet_decrypt_check to the client library.
4829 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4830 to send with specified source and destination information.
4832 * Channel message delivery between routers was broken after the
4833 channel key distribution was fixed earlier. The channel key
4834 was used be to distributed to other routers as well which is not
4835 allowed by the protocol. Now this is fixed and channel keys
4836 really are cell specific and the channel message delivery between
4837 routers comply with the protocol specification.
4839 * Fixed various commands in server to check also the global list
4840 for the channel entry and not just the local list. The affected
4841 file silcd/command.c.
4843 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4845 * Added assert()s to buffer formatting and unformatting routines
4846 to assert (if --enable-debug) when error occurs. Affected
4847 file: lib/silcutil/silcbuffmt.c.
4849 * Changed to auto-reconnect to check whether the remote host is
4850 router and register the re-connect timeout if it is. It used
4851 to check that whether we are normal server, but router must do
4852 auto-reconnect with another router as well. Affected file
4855 * Removed the [<key len>] option from CMODE command as the cipher
4856 name decides the key length, nowadays. See the defined ciphers
4857 from the protocol specification.
4859 * Added [<hmac>] option to the CMODE command to define the HMAC
4860 for the channel. Added SILC_CMODE_HMAC channel mode.
4862 * Added [<hmac>] option for the JOIN command so that user can
4863 select which HMAC is used to compute the MACs of the channel
4866 * Added Hmac field to the Channel Message Payload. The integrity
4867 of plaintext channel messages are now protected by computing
4868 MAC of the message and attaching the MAC to the payload. The
4869 MAC is encrypted. Now, it is clear that this causes some
4870 overhead to the size of the packet but rationale for this is that
4871 now the receiver can verify whether the channel message decrypted
4872 correctly and also when private keys are set for the channel the
4873 receiver can decrypt the packet with several keys and check from
4874 the MAC which key decrypted the message correctly.
4876 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4877 lib/silccrypt/silccipher.[ch].
4879 * Added silc_hash_len to return the digest length into the
4880 lib/silcrypt/silchash.[ch].
4882 * Rewrote parts of Silc Channel Payload interface in the
4883 lib/silccore/silcchannel.[ch]. The encode function now also
4884 encrypts the packet and parse function decrypts it.
4886 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4888 * Fixed a minor formatting bug in the SKE's key material processing.
4889 It actually might have processed the keys wrong way resulting
4892 * Redefined the mandatory HMAC algorithms and added new algorithms.
4893 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4894 and hmac-md5 truncated to 96 bits. The mandatory is now
4895 hmac-sha1-96. Rest are optional (including the one that used
4896 to be mandatory). Rationale for this is that the truncated HMAC
4897 length is sufficient from security point of view and can actually
4898 make the attack against the HMAC harder. Also, the truncated
4899 HMAC causes less overhead to the packets. See the RFC2104 for
4902 * Added new [hmac] configuration section. The SKE used to use
4903 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4904 is of course wrong. The official names that must be proposed in
4905 the SKE are the ones defined in the protocol specification
4906 (hmac-sha1-96 for example). The user can configure any hmac
4907 using any hash function configured in the [hash] section. At
4908 least, the mandatory must be configured.
4910 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4912 * Added HMAC list to the SKE proposal list. It has now both
4913 hash algorithm list and HMAC list. This makes the protocol
4914 incompatible with previous versions. The SKE now seems to work
4915 the way it is supposed to work, for the first time actually.
4917 * Defined plain Hash algorithms to the protocol specification.
4920 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4922 * Implemented support for key agreement packets into the server.
4923 Added functions silc_server_key_agreement and
4924 silc_server_send_key_agreement. Other than these functions,
4925 server has nothing to do with this packet.
4927 * Added support for private message key packets into the server.
4928 Added functions silc_server_private_message_key and
4929 silc_server_send_private_message_key.
4933 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4934 called in the protocol's final callback instead in the END
4935 protocol state. This makes a little more sense and in the same
4936 time in client we can use the same protocol routines for normal
4937 key exchange and to key agreement packet handling as well.
4939 * Added to both client's and server's KE protocol context the
4940 SilcSKEKeyMaterial pointer to save the key material. We will
4941 bring the key material to the protocol's final callback by doing
4942 this. The final callback must free the key material.
4944 * Added SKE's packet_send callback into client's KE protocol
4945 context so that the caller can choose what packet sending function
4946 is used. This way we can use different packet sending when
4947 doing normal SKE when doing key agreement packet handling (in
4948 the key agreement packet handling we do not want to encrypt
4951 * Implemented the responder side of the key agreement routines
4952 in the client. The client can now bind to specified port and
4953 accept incoming key negotiation. The key material is passed
4954 to the application after the protocol is over.
4956 * Implemented the processing of incoming Key Agreement packet
4957 in the client. Added function silc_client_key_agreement to
4960 * Implemented the intiator side of the key agreement routines
4961 in the client. The client can now initiate key agreement with
4962 another remote client. The key material is passed to the
4963 application after the protocol is over.
4965 * Created client_keyagr.c to include all the key agreement
4968 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4969 SILC_TASK_CALLBACK except that it is not static.
4971 * Created client_notify.c and moved the Notify packet handling
4972 from the client.[ch] into that file.
4974 * Created client_prvmsg.c and moved all private message and
4975 private message key routines from the client.[ch] into that file.
4977 * Create client_channel.c and moved all channel message and
4978 channel private key routines from the client.[ch] into that file.
4980 * Changed silc_client_get_client_by_id_resolve to resolve with
4981 WHOIS command instead of IDENTIFY command, in the file
4982 lib/silclient/idlist.c.
4984 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4986 * Implemented the SKE's responder side to the Client library.
4988 * When FAILURE is received to the protocol do not trust it
4989 blindly. Register a timeout to wait whether the remote closes
4990 the connection as it should do it, only after that process the
4991 actual failure. This was changed to both client and server.
4993 * Added client_internal.h to include some of the structures
4994 there instead of client.h in lib/silcclient/.
4996 * Added function silc_task_unregister_by_callback to unregister
4997 timeouts by the callback function.
4999 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * Some "Incomplete WHOIS info" errors has been appearing on the
5002 log files. Took away the entry->userinfo check from WHOIS
5003 reply sending. The entry->userinfo is now " " if client did not
5004 provide one. I thought this was fixed earlier but something
5005 is wrong still. Let's see if the error still appears.
5007 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5009 * Fixed a minor bug in the login when the channel key is
5010 re-generated in the server. It used to generate the key in
5011 wrong order and thus caused problems in the channel traffic.
5013 * Fixed a minor bug in channel key distsribution after
5014 KICK command. The key was not sent to the router even though
5017 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Added silc_ske_process_key_material_data as generic routine
5020 to process any key material as the SILC protocol dictates. The
5021 function is used by the actual SKE library but can be used by
5022 applications as well. This relates to the private message keys
5023 and the channel private keys since they must be processed the
5024 same way the normal SILC session keys. The protocol dictates
5025 this. Affected files: lib/silcske/silcske.[ch].
5027 Added also silc_ske_free_key_material to free the
5028 SilcSKEKeyMaterial structure.
5030 * Defined silc_cipher_set_key function to set the key for
5031 cipher without using the object's method function. The affected
5032 files: lib/silccrypt/silccipher.[ch].
5034 * Implemented silc silc_client_add_private_message_key,
5035 silc_client_add_private_message_key_ske,
5036 silc_client_del_private_message_key,
5037 silc_client_list_private_message_keys and
5038 silc_client_free_private_message_keys functions in the
5041 Added functions silc_client_send_private_message_key to send
5042 the Private Message Key payload and silc_client_private_message_key
5043 to handle incoming Private Message Key payload.
5045 * Added Cipher field to the Private Message Key payload to set
5046 the cipher to be used. If ignored, the default cipher defined
5047 in the SILC protocol (aes-256-cbc) is used.
5049 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Removed lib/silcclient/ops.h file.
5053 Redefined parts of the SILC Client Library API. Created new
5054 file silcapi.h that deprecates the ops.h file and defines the
5055 published Client Library API. Defined also private message key
5056 API and channel private key API into the file.
5058 This is the file that the application must include from the
5059 SILC Client Library. Other files need not be included by
5060 the application anymore.
5062 * Added new key_agreement client operation callback and also
5063 defined the Key Agreement library API for the application.
5065 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5067 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5068 is used by clients to request key negotiation between another
5069 client in the SILC network. If the negotiation is started it
5070 is performed using the SKE protocol. The result of the
5071 negotiation, the secret key material, can be used for example
5072 as private message key.
5074 Implemented the Key Agreement payload into the files
5075 lib/silccore/silauth.[ch].
5077 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5079 * Redefined ciphers for the SILC protocol. Added some new ciphers
5080 and defined the key lengths for the algorithms. Changed the
5081 code accordingly. The default key length is now 256 bits.
5083 * Fixed SKE key distribution function silc_ske_process_key_material
5084 when the key length is more than 128 bits. The default key
5085 length in SILC is now 256 bits.
5087 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5088 to indicate unsupported algorithm.
5090 * Renamed rijndael.c to aes.c and all functions as well.
5092 * Fixed a long standing channel key setting bug in client library.
5093 Weird that it has never surfaced before.
5095 * Fixed bug in channel deletion. If the entire channel is removed
5096 then it must also delete the references of the channel entry
5097 from the client's channel list as the client's channel entry and
5098 the channel's client entry share same memory.
5100 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * Implemented CONNECT and SHUTDOWN commands in the client.
5104 * Implemented CLOSE command to the client.
5106 * Added the function silc_idlist_find_server_by_name into the
5107 files silcd/idlist.[ch].
5109 Added the function silc_idlist_find_server_by_conn into the
5110 files silcd/idlist.[ch].
5112 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5114 * DIE command was renamed to SHUTDOWN. Updated the both code
5117 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5118 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5120 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5123 * Added function silc_server_create_connection function to create
5124 connection to remote router. My server implementation actually
5125 does not allow router to connect to normal server (it expects
5126 that normal server always initiates the connection to the router)
5127 so the CONNECT command is only good for connecting to another
5130 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5132 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5133 or some other client was kicked from the channel.
5135 Implemented the handling of the notify type to both client
5138 Implemented silc_server_send_notify_kicked to send the KICKED
5139 notify. It is used to send it to the server's primary router.
5141 * Implemented the KICK command into server and client.
5143 * Added `query' argument to the silc_idlist_get_client function
5144 to indicate whether to query the client from server or not if
5147 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5148 to indicate that the client is not channel founder.
5152 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5154 * Removed the rng context from SilcPacketContext structure and
5155 changed that the packet routine uses the Global RNG API.
5157 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Added support for quit message that client can "leave" on the
5160 channel when it quits the SILC. It is ditributed inside the
5161 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5163 Added silc_server_free_client_data that will take the
5164 signoff message as argument.
5166 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5168 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5170 * Updated parts of the protocol specification to keep it up
5173 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5175 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5176 payloads in one packet.
5178 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5179 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5180 use now the new List flag.
5182 * Also deprecated the following packet types: REPLACE_ID,
5183 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5185 * Added list support for Notify packet in server.
5187 * Added silc_server_send_notify_channel_change to send the
5188 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5189 the silc_server_send_replace_id.
5191 * Added silc_server_send_notify_nick_change to send the
5192 NICK_CHANGE notify type. Deprecates the function
5193 silc_server_send_replace_id.
5195 * Added silc_server_send_notify_join to send the JOIN notify type.
5196 Deprecates the function silc_server_send_new_channel_user.
5198 * Added silc_server_send_notify_leave to send LEAVE notify type.
5199 Deprecates the function silc_server_send_remove_channel_user.
5201 * Added silc_server_send_notify_cmode and
5202 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5203 types. Deprecates the silc_server_send_set_mode function.
5205 * Added SERVER_SIGNOFF notify type to indicate that server has
5206 quit. This means that all clients on the channel from that
5207 server will drop. This can be also used when netsplit happens.
5209 Deprecated REMOVE_ID packet type since it is not needed anymore
5212 Added silc_server_send_notify_server_signoff to send the
5213 SERVER_SIGNOFF notify type. Deprecates the function
5214 silc_server_send_remove_id.
5216 Added also silc_server_send_notify_signoff to send the
5217 SIGNOFF notify type.
5219 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5220 SILC protocol from this day on. Changed the protocol
5221 specification as well.
5223 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5224 notify type. It is used between routers to notify about
5225 topic changes on a channel.
5227 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5230 * Partly updated the protocol specification to comply with the
5231 changes now made. It is still though a bit outdated.
5233 * The JOIN notify type now takes one extra argument <Channel ID>.
5234 The packet used to be destined to the channel but now the
5235 JOIN type may be sent as list thus it is impossible to
5236 destine it to any specific channel. By adding this argument
5237 it is again possible.
5239 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5241 * Added CREDITS file. The CHANGES and CREDITS file will appear
5242 in the distribution as well.
5244 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5246 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5247 types in the server's silcd/packet_receive.c.
5249 * Implemented CMODE and CUMODE to work in router environment.
5251 * Fixed minor encoding and decoding buglet from the
5252 lib/silccore/silcmode.c.
5254 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5257 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5259 * Changed all SilcConfigServer* and silc_config_server* to
5260 SilcServerConfig* and silc_server_config*, respectively.
5263 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5265 * Associated the ID (client or server ID) to the Authentication
5266 Payload to avoid any possibility of forging. Updated the
5267 protocol specification and the code accordingly.
5269 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * The RSA key length is now save to the RsaKey context in the
5272 key generation process in lib/silccrypt/rsa.c. The key length
5273 is now used to figure out the maximum size of the block allowed
5274 to be encrypted/signed.
5276 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5277 is equivalent to the silc_mp_mp2bin but does not allocate any
5280 * Changed silc_mp_mp2bin API to take length argument. If it is
5281 non-zero then the buffer is allocated that large. If zero, then
5282 the size is approximated using silc_mp_sizeinbase, which however
5285 * Created Global RNG API which is global RNG that application can
5286 initialize. After initializing, any routine anywhere in the
5287 code (including library) can use RNG without allocating a new
5288 RNG object. This was done to allow this sort of use of the
5289 RNG in code that has no chance to allocate RNG object. All
5290 applications currently allocate this and many routines in the
5291 library use this. Affected file lib/silccrypt/silcrng.[ch].
5293 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5294 it to use the Global RNG API.
5296 * Defined Authentication Payload into protocol specification that
5297 is used during SILC session to authenticate entities. It is
5298 used for example by client to authenticate itself to the server
5299 to obtain server operator privileges.
5301 Implemented this payload into the lib/silccore/silcauth.[ch].
5302 Implemented also routines for public key based authentication
5303 as the new protocol specification dictates.
5305 Moved definitions of different authentication methods from
5306 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5308 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5309 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5310 silc_pkcs_verify_with_hash functions into the file
5311 lib/silccrypt/silcpkcs.[ch].
5313 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5315 * The client entry's userinfo pointer must be always valid.
5316 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5317 will fail since it requires the userinfo. Now, the userinfo
5318 is allocated as "" if actual userinfo does not exist. Actually,
5319 it must exist and it is totally Ok to drop client connections
5320 that does not announce the userinfo. However, we will make
5321 this workaround for now.
5323 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5324 to return the remote port by socket.
5326 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5328 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5329 SILC_SERVER_PENDING_EXEC and added an new macro
5330 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5331 data or when error occurs while processing the pending command.
5333 Added new argument `destructor' into silc_server_command_pending
5334 and to the SilcServerCommandPending object. This destructor is
5335 now called after calling the pending callback or if error occurs
5336 immediately. If error occurs the actual pending callback won't
5337 be called at all - only the destructor. The destructor may be
5338 NULL if destructor is not needed.
5340 All this applies for client library code as well. Similar
5341 changes were made there as well for the pending commands.
5343 In the client, the application must now allocate the
5344 SilcClientCommandContext with the silc_client_command_alloc
5347 * Added reference counter to the SilcServerCommandContext. Added
5348 function silc_server_command_alloc and silc_server_command_dup
5351 Same type of functions added to the client library for the same
5354 * Removed the cmd_ident from IDListData away since it is now
5355 global for all connections. It is the command identifier used
5356 in command sending and with pending commands. The affected file
5359 * Added reference counter to the SilcSocketConnection objecet to
5360 indicate the usage count of the object. The object won't be
5361 freed untill the reference counter hits zero. Currently only
5362 server uses this, and client ignores it. The client must be
5363 set to use this too later. The affected files are
5364 lib/silccore/silcsockconn.[ch]. Added also the function
5365 silc_socket_dup to increase the reference counter.
5367 This was mainly added because it is possible that the socket
5368 is removed underneath of pending command or other async
5369 operation. Now it won't be free'd and proper DISCONNECTING
5370 flags, etc. can be set to avoid sending data to connection that
5371 is not valid anymore.
5373 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5374 the connection. After that it sets SILC_SET_DISCONNECTED.
5375 It is, however, possible that the socket data is not still freed.
5376 The silc_server_packet_process now checks that data is not
5377 read or written to connection that is DISCONNECTED. The socket
5378 get's freed when the reference counter hits zero.
5380 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5382 * Changed the client operation API: channel_message operation's
5383 `sender' is now the client entry of the sender, not the nickname
5384 and the `channel' is the channel entry, not the channel name.
5386 In the private_message operation the `sender' is now also the
5387 client entry of the sender not the nickname.
5389 Affected file is lib/silcclient/ops.h and all applications
5390 using the client operations.
5392 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Moved the calling of ops->connect() from connect_to_server_final
5395 into receive_new_id functin since that is the point when the
5396 client is actually allowed to send traffic to network. The
5397 affected file is lib/silcclient/client.c.
5399 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5401 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5402 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5403 (if needs broadcasting) instead of broadcasting the packets one
5404 by one which would make a burst in the network traffic.
5406 * Added `broadcast' argument to the functions in silcd/server.[ch]
5407 silc_server_create_new_channel[_with_id] to indicate whether
5408 to send New Channel packet to primary router.
5410 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Added new function into the silcd/server.[ch] files:
5413 silc_server_create_new_channel_with_id to create new channel with
5414 already existing Channel ID.
5416 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5417 lib/silccore/silcpacket.h. This packet is used t send list of
5418 Set Mode payloads inside one packet. Server uses this to set
5419 the modes for the channels and clients on those channels, that it
5420 announced to the router when it connected to it. The protocol
5421 specification has been updated accordingly.
5423 * The silc_server_new_channel did not handle the packet coming
5424 from normal server as it normally does not send that. However,
5425 when it announces its channels it does send it. Implemented
5426 the support for that.
5428 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5429 into the file lib/silccore/id.h.
5431 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5433 * Fixed memory leaks in the functions silc_idlist_del_client,
5434 silc_idlist_del_channel and silc_idlist_del_server in the file
5435 silcd/idlist.c. All of those leaked like a sieve.
5437 * Fixed some small memory leaks in the client's function
5438 silc_client_notify_by_server.
5440 * Added functions into silcd/server.c: silc_server_announce_clients,
5441 silc_server_announce_channels and silc_server_announce_server.
5442 These functions are used by normal and router server to announce
5443 to its primary router about clients, channels and servers (when
5444 router) that we own. This is done after we've connected to the
5447 These functions effectively implements the following packet types:
5448 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5449 and SILC_PACKET_NEW_ID_LIST.
5451 * Added new functions into the silcd/packet_receive.[ch]:
5452 silc_server_new_id_list, silc_server_new_channel_list and
5453 silc_server_new_channel_user_list to handle the incoming
5454 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5456 * Added support of changing Channel ID in the function
5457 silc_server_replace_id. If the server that announces a channel
5458 to the router already exists in the router (with same name but
5459 with different Channel ID), router is responsible to send
5460 Replace ID packet to the server and force the server to change
5461 the Channel ID to the one router has.
5463 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5464 client that the Channel ID has been changed by the router. The
5465 normal server sends this to the client. Client must start using
5466 the new Channel ID as the channel's ID.
5468 Implemented handling of this new type into lib/silcclient/client.c
5469 into the function silc_client_notify_by_server.
5471 * Added new function silc_idlist_replace_channel_id into the files
5472 silcd/idlist.[ch] to replace the Channel ID.
5474 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5476 * Call silc_server_command_identify_check always when processing
5477 the IDENTIFY command in silcd/command.c
5479 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5481 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5482 send keepalive packets. The packet can be sent by clients,
5483 servers and routers.
5485 Added function silc_socket_set_heartbeat into the file
5486 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5487 If not set, the heartbeat is not performed. The actual
5488 heartbeat is implemented in the low level socket connection
5489 library. However, application is responsible of actually
5492 Added silc_server_send_heartbeat to send the actual heartbeat
5493 packet into silcd/packet_send.[ch]. Server now performs
5494 keepalive with all connections.
5496 * Added silc_task_get_first function into lib/silcutil/silctask.c
5497 to return the timeout task with shortest timeout. There was a bug
5498 in task unregistration that caused problems. TODO has been
5499 updated to include that task system must be rewritten.
5501 * The client library will now resolve the client information when
5502 receiving JOIN notify from server for client that we know but
5503 have incomplete information.
5505 * Rewrote parts of silc_server_remove_from_channels and
5506 silc_server_remove_from_one_channel as they did not remove the
5507 channel in some circumstances even though they should've.
5509 * Encryption problem encountered in server:
5511 The LEAVE command used to send the Channel Key packet to the
5512 router immediately after generating it. However, the code
5513 had earlier sent Remove Channel user packet but not immediately,
5514 ie. it was put to queue. The order of packets in the router
5515 was that Channel Key packet was first and Remove Channel User
5516 packet was second, even though they were encrypted in the
5517 reverse order. For this reason, MAC check failed. Now, this
5518 is fixed by not sending the Channel Key packet immediately but
5519 putting it to queue. However, this is more fundamental problem:
5520 packets that are in queue should actually not be encrypted
5521 because packets that are sent immediately gets encrypted
5522 actually with wrong IV (and thus MAC check fails). So, packets
5523 that are in queue should be encrypted when they are sent to
5524 the wire and not when they put to the queue.
5526 However, the problem is that the current system has not been
5527 designed to work that way. Instead, the packet is encrypted
5528 as soon as possible and left to the queue. The queue is then
5529 just purged into wire. There won't be any fixes for this
5530 any time soon. So, the current semantic for packet sending
5533 o If you send packet to remote host and do not force the send
5534 (the packet will be in queue) then all subsequent packets to the
5535 same remote host must also be put to the queue. Only after the
5536 queue has been purged is it safe again to force the packet
5539 o If you send all packets immediately then it safe to send
5540 any of subsequent packets through the queue, however, after
5541 the first packet is put to queue then any subsequent packets
5542 must also be put to the queue.
5544 Follow these rules and everything works fine.
5546 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5548 * Added new function silc_server_remove_clients_by_server to
5549 remove all client entries from ID list when the server connection
5550 is lost. In this case it is also important to invalidate all
5551 client entires as they hold the invalid server entry. This
5552 fixes fatal bug when server has lost connection and will reconnect
5555 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5557 * Made some sanity checks to silc_server_daemonise like to check
5558 whether the requested user and group actually exists.
5560 * Added sanity check to SKE's silc_ske_responder_finish to check
5561 that the public and private key actually is valid.
5563 * Invalidate the client's nickname when receiving Replace ID
5564 packet and the Client ID is being replaced. This means that the
5565 server will query the nickname if someone needs it (client)
5568 * Sort the ID Cache in client library when the ID Cache data
5569 has changed (needs sorting).
5571 * Do not allow for SILC client to create several connections to
5572 several servers. The client does not support windows right now
5573 and generating multiple connections causes weird behaviour.
5575 Irssi-silc client does support windows and can handle several
5576 connections without problems, see: www.irssi.org and SILC plugin.
5578 * Fixed some places where client was added to the IDList. The
5579 rule of thumb is following (in order to get everything right):
5580 If the client is directly connected local client then the
5581 `connection' argument must be set and `router' argument must be
5582 NULL to silc_idlist_add_client function. If the client is not
5583 directly connected client then the `router' argument must
5584 bet set and the `connection' argument must be NULL to the
5585 silc_idlist_add_client function.
5587 * The funtion silc_server_packet_send_local_channel actually did
5588 not check whether the client was locally connected or not. It
5589 does that now. Fixed a bug related to LEAVE command.
5591 * Fixed Remove Channel User payload parsing bug in server's
5592 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5594 * The server's silc_server_save_channel_key now checks also the
5595 global ID list for the channel as it might not be in the local
5596 list. Fixed a bug related to LEAVE command.
5598 * Is this the end of the [<unknown>] buglet that has been lurking
5599 around for a long time? A little for loop fix in server's
5600 silc_server_command_whois_parse that is used by both IDENTIFY
5601 and WHOIS command. At least, this was a clear bug and a cause
5602 of one type of [<unknown>] buglet.
5604 * WHOIS and IDENTIFY commands call the function
5605 silc_server_command_[whois/identify]_check function even if
5606 we are not router server.
5608 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5610 * Added --with-gmp configuration option. If set the GMP
5611 is always compiled in the SILC source tree. If not set then
5612 it is checked whether the system has the GMP3 installed. If
5613 it has then the GMP won't be compiled (the system's headers
5614 and library is used), if it doesn't have it then the GMP is
5615 compiled in the SILC source tree.
5617 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5619 * Changed RSA private exponent generation to what PKCS #1
5620 suggests. We try to find the smallest possible d by doing
5621 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5622 not security fix but optimization.
5624 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5626 * Added new config entry [Identity] to fork the server and run
5627 it as specific user and group. A patch from Bostik.
5629 * Imported Dotconf configuration library into lib/dotconf.
5630 This will be used to create the SILC configuration files later.
5631 It will appear in the distsribution after this commit.
5633 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5635 * A big code auditing weekend happening. Auditing code for
5636 obvious mistakes, bugs and errors. Also, removing any code
5639 Removed files for being obsolete:
5641 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5642 inline in the file lib/silcutil/silcbuffer.h)
5644 o lib/silcutil/silcbufutil.c (the header has inline versions)
5646 Changed code to fix possible error conditions:
5648 o The buffer formatting routines now check that the destination
5649 buffer really has enough space to add the data. This applies for
5650 both buffer formatting and unformatting
5651 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5652 unformatting was changed to accomodate following rules:
5653 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5654 sent to the function while XXX_*STRING will not allocate or copy
5655 the data into the buffer. Instead it sets the pointer from the
5656 buffer into the pointer sent as argument (XXX_*STRING used to
5657 require that the pointer must be allocated already). This change
5658 makes this whole thing a bit more consistent and more optimized
5659 (note that the data returned in the unformatting with XXX_*STRING
5660 must not be freed now). The routines return now -1 on error.
5662 o Tried to find all code that use buffer_format and buffer_unformat
5663 and added return value checking to prevent formatting and
5664 especially unformatting errors and possible subsequent fatal
5667 o Changed ske->x and ske->KEY to mallocated pointers in
5668 lib/silcske/silcske.h. Fixed possible data and memory leak.
5670 o Added return value checking to all *_parse* functions. Fixed
5671 many memory leaks as well.
5673 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5674 so that buffer overflows would not happen. All code now also
5675 checks the return value as it can fail.
5677 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5679 * Added reconnection support to server if the normal server looses
5680 its connection to the router (for example if router is rebooted).
5681 The server performs normal reconnection strategy implemented
5682 to the server. Affected file silcd/server.c.
5684 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5686 * Added new packet type SILC_PACKET_SET_MODE that is used to
5687 distribute the information about changed modes (for clients,
5688 channels and clients channel modes) to all routers in the
5689 network. Updated the protocol specification accordingly.
5691 Added functions into silcd/packet_send.c and
5692 silcd/packet_receive.c: silc_server_send_set_mode,
5693 silc_server_set_mode.
5695 Added new files silcmode.[ch] into lib/silccore that implements
5696 the encoding and decoding of Set Mode Payload. Added new type
5697 SilcSetModePayload. Moved the definitions of different modes
5698 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5700 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5702 * Oops, a little mistake in server's connection authentication
5703 protocol. The protocol is not ended with FAILURE but with
5704 SUCCESS if the authentication is Ok. :) Affected file is
5707 * Implemented NICK_CHANGE notify handling in server in the file
5708 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5709 the local clients on the channel. After the changing nickname
5710 in router environment snhould work and the [<unknown>] nickname
5711 should appear no more.
5713 The silc_server_replace_id function that receives the Replace ID
5714 payload now sends the NICK_CHANGE notify type also in the file
5715 silcd/packet_receive.c
5717 * Changed WHOIS and IDENTIFY command to support the maximum amount
5718 of arguments defined in protocol specs (3328 arguments). This
5719 fixed a bug that caused problems when there were more than three
5722 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5724 * Added extra parameter, command identifier, to the
5725 silc_client_send_command so that explicit command identifier
5728 Changed that ID list routines uses specific command identifier
5729 when sending WHOIS/IDENTIFY requests to the server so that they
5730 can be identified when the reply comes back.
5732 Affected files lib/silcclient/command.[ch],
5733 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5735 * Added `sender' argument to silc_server_packet_send_to_channel
5736 to indicaet the sender who originally sent the packet to us
5737 that we are now re-sending. Ignored if NULL. Affected file
5738 silcd/packet_send.[ch].
5740 * Added some server statistics support in silcd/server_internal.h
5741 SilcServerStatistics structure and around the server code. Also
5742 send some nice statistics information when client is connecting
5745 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5747 * Fixed channel ID decoding in server's JOIN command reply in
5748 silcd/command_reply.c
5750 * Fixed braodcasting of replace ID payload to not to send it if
5751 we are standalone server in silcd/packet_receive.c.
5753 * Fixed all channel message sending routines to not to send
5754 packets to clients that has router set, since they are routed
5755 separately in the same function earlier. Affects file
5756 silcd/packet_send.c and all channel packet sending functions.
5758 * In USERS reply, res_argv[i] are not allocated, the table
5759 is allocated. Thus changed that free the table, not its
5762 * In server's whois_check and identify_check if the client is
5763 locally connected do not send any WHOIS commands - they are not
5766 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5768 * Fixed some minor bugs in client when sending WHOIS command. The
5769 arguments was in wrong order.
5771 * Removed statis function add_to_channel from server in
5772 silcd/command.c that was previously used with the joining but
5775 * Tested USERS command in router environment successfully with two
5776 routers, two servers and two clients.
5778 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5780 * Reorganized the USERS command and command reply in client library
5781 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5782 When the command is given by user we register a pending command
5783 callback that will reprocess the command after the reply has been
5784 received from the server. When reprocessing the packet we then
5785 display the information. Thus, the USERS information is displayed
5786 now in the command callback instead of in the command reply
5787 callback. The processing of the command is same as previously
5788 when server has sent the command reply in the JOINing process.
5790 * Added to USERS command in silcd/command_reply.c to join the client,
5791 we didn't use to know about, to the channel after we've created
5792 a client entry for it. Also, for clienet we did know already still
5793 check whether it is on the channel or not and add it if not.
5795 * Removed silc_server_command_join_notify as the function and its
5798 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5800 * Changed the client's pending command handling to the same as the
5801 server's pending command handling. It is also now possible to
5802 execute command reply functions from other command reply
5803 function as the function callbacks for commands and command
5804 replies are one and same. The pending commands are not static
5805 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5806 in client connection context. Thus, pending commands are server
5807 connection specific as it is convenient.
5809 Changed the function silc_client_command_pending and
5810 silc_client_command_pending_del and added new function
5811 silc_client_command_pending_check. Removed the
5812 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5815 * Added cmd_ident, current command identifier, to the client
5816 connection context in lib/silcclient/client.h to keep track on
5817 command identifiers used in command sending. Client's command reply
5818 function handling now supports the mandatory command identifiers.
5820 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5821 funtions in client to fully support pending command callbacks.
5823 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5824 as one of the arguments to the application in the command reply
5827 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5828 before first releasing SILC but came back. Now it is removed again
5829 and should come back nomore. The FORWARDED flag was used only
5830 by the JOINing procedure by forwarding the command packet to router.
5831 Now, the JOINing procedure has been changed to more generic (due
5832 to various router environment issues) and FORWARDED is not needed
5833 anymore for anything. The protocol specification is yet to be
5836 Now, removed silc_server_packet_forward from server and the flag
5837 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5839 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5841 * Renamed NAMES command to USERS command. The NAMES was named that
5842 due to historical reasons. Now it is renamed. Also, rewrote
5843 parts of the USERS command. The nickname list is not sent anymore
5844 by the server. Only Client ID and mode lists are sent in the USERS
5845 command. Changed this also to the protocol specification.
5847 The client now resolves the names and stuff after it receives
5848 the USERS list from the server when joining to the channel.
5850 * WHOIS and IDENTIFY commands has been changed to support multiple
5851 Client ID's per command. One can now search for multiple users
5852 in the network by sending only one WHOIS or IDENTIFY command.
5853 Changed the code and the protocol specifications.
5855 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5856 uses silc_server_command_whois_parse to parse the request. */
5858 * If normal server, do not parse the WHOIS and IDENTIFY requests
5859 before sending it to the router. Saves some time.
5861 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5863 * Fixed JOIN command on client library. Wrong number of arguments
5864 used to crash the client.
5866 * Added silc_server_channel_has_global function to check whether
5867 channel has global users or not.
5869 * Added silc_server_channel_has_local function to check whether channel
5870 has locally connected clients on the channel.
5872 * The silc_server_remove_from_one_channel now checks whether the
5873 channel has global users or not after given client was removed from
5874 the channel. It also checks whether the channel has local clients
5875 on the channel anymore. If it does not have then the channel entry
5876 is removed as it is not needed anymore.
5878 * The silc_server_notify now checks on JOIN notify whether the joining
5879 client is one of locally connected or global. If it is global then
5880 the channel has now global users on the channel and that is marked
5881 to the channel entry. Also, it now saves the global client to
5882 global list who is joining and JOINs it to the channel. This is
5883 for normal server, that is.
5885 Changed silc_server_send_notify_on_channel,
5886 silc_server_packet_relay_to_channel and
5887 silc_server_packet_send_to_channel check if we are normal server
5888 and client has router set (ie. global client) do not send the
5889 message to that client, as it is already routed to our router.
5891 * Implemented LEAVE notify type handling in silc_server_notify
5894 * Tested LEAVE command in router environment successfully. Tested
5895 with two routers, two servers and two clients.
5899 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5901 * Implemented SIGNOFF notify type handling in silc_server_notify
5904 * silc_server_remove_id now removes the client entry from all channels
5905 it has joined and thusly sends SIGNOFF notify type.
5907 * Rewrote the NAMES list generation in server by removing two excess
5908 loops. The lists are created now inside one loop.
5910 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5912 * silc_server_remove_channel_user checks now also global list
5913 for channel and client.
5915 * silc_server_new_channel_user checks now both local and global
5916 list for channel and client. Fixed a bug in client id decoding.
5917 Used to decode wrong buffer.
5919 * silc_server_channel_message checks now both local and global
5920 list for channel entry.
5922 * Tested channel joining (hence JOIN) in router environment
5923 successfully. Tested with two routers, two servers and two
5926 * Tested channel message sending in router environment successfully.
5928 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Added silc_server_save_channel_key into server.[ch] to save the
5931 received channel key in Channel Key payload processing. It is
5932 also used in JOIN command reply handling.
5934 Equivalent function silc_client_save_channel_key added into
5935 client.[ch] into client library.
5937 * Changed JOIN command reply to send information whether the channel
5938 was created or not (is existing already) and the channel key
5939 payload. Changed protocol specs accordingly.
5941 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5942 the request was sent by ID and not by nickname. Crashed on
5945 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5947 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5948 now correctly save the received data.
5950 * silc_server_free_sock_user_data now notifies routers in the
5951 network about entities leaving the network.
5953 At the same time implemented functions silc_server_remove_id
5954 and silc_server_send_remove_id to receive and send REMOVE_ID
5955 packets. The packet is used to notify routers in the network
5956 about leaving entities. The ID removed will become invalid in
5959 * Added function silc_idlist_del_server into server. Removes and
5960 free's server entry from ID list.
5962 * silc_server_private_message function now checks, if we are router,
5963 that the destination ID really is valid ID, naturally.
5965 * In router when NEW_ID packet is received (for new client) the
5966 hash of the Client ID is saved in the ID Cache but the
5967 client->nickname is set to NULL, instead of putting the hash
5970 IDENTIFY command now also checks that client->nickname must be
5971 valid. If it is not if will request the data from the server who
5972 owns the client. Added new function
5973 silc_server_command_identify_check.
5975 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5976 to set the command to already allocated Command Payload.
5978 * Tested private message sending in router environment with two
5979 routers, two servers and two clients. Fixed minor bugs and now
5982 * Fixed segfault from client's NAMES command. Used to crash if
5985 * Forwarded packets must not be routed even if it is not destined
5986 to the receiver. Changed server code comply with this.
5988 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5990 * Added `require_reverse_mapping' boolean value to ServerParams
5991 structure. If TRUE (not default) the server will require that
5992 the connecting host has fully qualified domain name.
5994 If the reverse mapping is not required and hostname could not be
5995 found the IP address is used as hostname.
5997 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5999 * Implemented version string checking to both client and server.
6000 The check is incomplete currently due to the abnormal version
6001 strings used in development version of SILC.
6003 * Changed all command functions in server to use the new
6006 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6008 * Changed char *data to unsigned char *data in ID Cache system to
6009 support binary data as ID Cache data. Changed code to support
6010 binary data in lib/silccore/idcache.c.
6012 * Renamed silc_server_packet_relay_command_reply to
6013 silc_server_command_reply as it is normal packet receiving
6014 function. Rewrote the function to accept command replys for
6015 servers and not only for clients.
6017 * Mark remote router always as registered server if we are connecting
6018 to it. Otherwise, commands sent by the router to us are ignored.
6020 * All ID List find routines now returns the ID Cache Entry pointer
6021 as well if requested.
6023 * WHOIS command works now in router environment, tested with two
6024 routers, two servers and two clients.
6026 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6027 in router environment (as it is almost equivalent to WHOIS) but
6028 hasn't been tested thoroughly. Added new functions:
6030 silc_server_command_identify_parse
6031 silc_server_command_identify_send_reply
6032 silc_server_command_identify_from_client
6033 silc_server_command_identify_from_server
6035 * Disabled route cache adding because adding two different ID's with
6036 same IP replaces the old cache entry thus giving wrong route.
6037 The entry->router->connection is always the fastest route anyway
6038 so route cache may not be needed. Of course, new routes maybe
6039 established after receiving the ID when the entry->router->connection
6040 might not be anymore the most optimal.
6042 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6044 * Add route cache for received ID for fast routing.
6046 * Added silc_server_packet_route to route received packet on router
6047 that is not destined to us.
6049 * Renamed silc_server_get_route to silc_server_route_get.
6051 * Added id_string and id_string_len fields into SilcServer to
6052 include encoded ServerID for fast comparing without excess
6053 encoding of the ID's.
6055 * Cleaned up WHOIS command on server side. Added following static
6058 silc_server_command_whois_parse
6059 silc_server_command_whois_check
6060 silc_server_command_whois_send_reply
6061 silc_server_command_whois_from_client
6062 silc_server_command_whois_from_server
6064 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6065 arguments in command replies. All command functions should be
6066 updated to use this macro.
6068 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6070 * Minor typo fixes on command reply handling on server.
6072 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6074 * Added silc_server_command_add_to_channel internal routine to add
6075 the client to the channel after router has created the channel and
6076 sent command reply to the server.
6078 * Added generic silc_server_send_command to send any command from
6081 * Use static buffer with ID rendering instead of duplicating data.
6083 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6085 * Fixed a channel user mode bug when joining to a channel server gave
6086 everybody channel founder rights, oops.
6088 * We mark ourselves as the router of the incoming server connection
6089 if we are router ourselves. This way we can check in some packet
6090 sending functions whether it is locally connected server. For
6091 incoming router connections we put NULL.
6093 * For router sending packets locally means now always sending the
6094 packet cell wide; to local clients and local servers. For normal
6095 server sending packet locally means sending it to only local
6098 * Fixed the JOIN command to really work in router environment. If the
6099 channel is created it is always created by the router. Router is
6100 also responsible of making the initial joining to the channel,
6101 sending JOIN notify to the sending server and distributing
6102 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6103 does not exist server doesn't do anything else but forward the
6104 command to the router which performs everything.
6106 * Added silc_server_send_channel_key function to send the Channel Key
6109 * Added silc_server_create_channel_key to create new channel key. The
6110 channel key is now re-generated everytime someone joins or leaves
6111 a channel, as protocol dictates. Note: channel->key_len is the
6114 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6116 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6117 packet_receive.[ch] to separate packet sending and receiving
6118 routines. The server.[ch] now includes everything else including
6119 actual packet processing (writing and reading data) and other
6122 Renamed silc_server_private_message_send_internal to
6123 silc_server_send_private_message. The routine is still though
6124 used only to relay private messages as server does not send
6125 private messages itself.
6127 Renamed silc_server_new_channel to silc_server_create_new_channel
6128 and added new function sicl_server_new_channel that handles the
6129 incoming New Channel packet. Added also new sending function
6130 silc_server_send_new_channel to send New Channel Payload.
6132 * Added new function silc_server_notify to process incoming notify
6133 packet to the server/router. Server may then relay the notify
6134 to clients if needed.
6136 * Added new function silc_server_new_channel_user to process incoming
6137 New Channel User packet. Router will redistribute the packet and
6138 send JOIN notify to its local clients and locally connected servers
6139 if needed. Normal server will send JOIN notify to its local client
6140 on same channel when received this packet. Added also corresponding
6141 sending function silc_server_send_new_channel_user to sent the
6144 * Added boolean route argument to send_notif_to_channel and
6145 packet_send_to_channel functions to attempt to route the packet
6146 if it is TRUE and send only locally if it is FALSE.
6148 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6150 * silc_server_replace_id now broadcasts the received replace ID
6151 packet if it is not broadcast packet already. The router must
6152 broadcast to inform other routers about changed ID.
6154 * Added backpointer to server's router into SilcServer context in
6155 silcd/server_internal.h.
6157 * Fixed silc_server_packet_broadcast to send correct broadcast
6160 * The channel key is now distributed to the local client as soon
6161 as it is received from the router (in router environment) so that
6162 no other packet may be sent for the channel until client has
6165 * silc_server_remove_channel_user now broadcasts the received
6166 Remove Channel User packet if it is not broadcast packet already.
6167 The router must broadcast to inform other routers about removed
6170 * Added users field into SilcPacketContext that is a reference count
6171 of the context. One can increase the reference count by calling
6172 silc_packet_context_dup which is now changed to just increase the
6173 reference count instead of duplicating the data. The reference
6174 count is decresed by calling silc_packet_context_free that will
6175 free the data after the reference count hits zero.
6177 For now on the packet context and everything allocated into it
6178 (including the raw packet from network) must be freed by calling
6179 the new silc_packet_context_free function. Added also new function
6180 silc_packet_context_alloc that must be used now to allocate the
6181 context. This also means that if a routine is asynchronous from
6182 silc_[client/server]_packet_parse_type the packet context must
6183 be duplicated by calling silc_packet_context_dup. Otherwise it
6184 gets free'd after silc_[client/server]_packet_parse_type returns.
6185 Also, one must remember that if packet is duplicated then its
6186 reference count must be decresed by calling the free function as
6187 many times as it was duplicated.
6189 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6190 from both client and server.
6192 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6194 * Made joining to a channel working in router environment.
6196 * Cleaned up JOIN command on server side and create function
6197 silc_server_command_join_channel internal routine to make the
6200 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6202 * Changed silc_command_pending list to SilcDList. Also, added
6203 `ident' field to SilcServerCommandPending structure to identify
6204 the reply and to call correct callback.
6206 Added silc_server_command_pending_check function to replace the
6207 corresnponding macro. The silc_command_pending list is not
6210 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6211 to set identifier to previously allocated Command Payload. It
6212 is used to set identifier for command when resending Command
6215 * Added silc_command_payload_encode_payload to encode Command
6216 Payload buffer from SilcCommandPayload structure.
6218 * Added silc_argument_payload_encode_payload to encode Argument
6219 payload buffer from SilcArgumentPayload structure.
6221 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6223 * Changed WHOIS command to support router connection on server side.
6224 The whois request is always sent to router unless the server is
6225 standalone server. After server has received the reply from the
6226 router will it send the reply to the client.
6228 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6229 broadcast received broadcast packet. The function is used only
6230 by router. The broadcast packet is always sent to the router's
6233 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6234 render given ID to printable string, for log files for example.
6236 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6238 * Made basic router to router connections working. At least they
6239 can now connect to each other but nothing really works the way
6240 they are supposed - yet.
6242 * Added new initiator token to RouterConnection configuration
6243 file in silcd/serverconfig.[ch]. It is used to tell whether we
6244 are the initiator to the remote router or whether we'll expect
6245 the other end to connect.
6247 * Moved registering of listener task to silc_server_init, hence
6248 the server starts listenning as soon as it is run, even if it
6249 does not have connections to other routers. Let's see how well
6252 * Changed default connection retry timeouts for more suitable in
6255 * Removed cipher and such arguments from silc_idlist_add_client
6256 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6257 Added new function silc_idlist_add_data to add the keys and stuff
6260 * Added SilcIDListData structure and added it to SilcClientEntry
6261 and SilcServerEntry as their first field in the structure. This
6262 way we can explicitly cast the ID entries to the SilcIDListData
6263 structure and get common data for the entries. In past, we had
6264 to first check what type of connection it is and then cast it to
6265 correct ID entry type. Now, we can directly cast the opaque
6266 pointer to the SilcIDListData (no matter what ID entry it actually
6267 is) and get the data needed.
6269 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6271 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6272 in some circumstances even if threre were timeout tasks, though not
6273 IO tasks, but tasks anyway. Now fixed.
6275 * Defined SilcServerConnection structure to hold connection specific
6276 stuff about directly connected servers and routers. The definition
6277 is currently in silcd/server_internal.h. I thought about having
6278 a bit more important role fro this struct but for now it is used
6279 only when connecting to other server (or router actually).
6281 * Added connecting retry support in server when connecting to
6282 router(s). The retry feature implement exponential backoff
6283 algorithm. Also, added SilcServerParams structure to hold default
6284 parameters for server. For now, it include these retry settings
6285 and are hard coded. After server is moded to be as Silc Server
6286 Library this structure will be more important.
6288 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * Changed client librarys channel->clients table to SilcList and
6291 changed code accordingly.
6293 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6295 * Changed client's channel table to SilcList and changed code
6296 accordingly. Also changed SilcChannelClientEntry to include back-
6297 pointer to the channel so that client entry can use that structure
6298 as list as well and we have fast cross-reference to the channel.
6299 This change dramatically decreased the complexity of channel
6300 handling with client entry and vice versa (removed one extra
6301 loop when searching for channel entry from many functions).
6303 * Changed server->sim from table to SilcDList and changed code
6306 * NAMES command can now be used from user interface. It will show
6307 the user list on the channel, neatly.
6309 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6310 Code now saves realname of the user if it becomes available.
6312 * Renamed configure.in to configure.in.pre and made ./prepare
6313 script to automatically add correct version string to
6314 configure.in which it creates from configure.in.pre.
6316 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6318 * NAMES command reply now shows users mode with the nickname when
6321 * Moved silc_client_ch[u]mode[_char] functions from
6322 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6323 place sucks, they are utility functions and should be in some
6326 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6328 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6331 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6335 * Added TRQ (efficient deque and list library) into lib/trq. This is
6336 a very good list library that is currently used in the SILC. Defined
6337 SilcList API over the library because I didn't like the API very
6338 much. See lib/trq/silclist.h for the API and examples of how to
6339 use the API. Fixed various places in the code to use the new
6340 SilcList API. The SilcList is meant for lists that has a structure
6341 already defined as a list. It is not suitable to add just some
6342 context to the list (in TRQ, the context is the list actually).
6344 So, I defined SilcDList that can be used for the purpose where
6345 predefined list structure does not exit. This can be used as
6346 such list. Now some context just can be added to the SilcDList.
6347 Currently this list is not used in the SILC just yet, though there
6348 are a lot places where this can replace dynamically allocated
6349 tables and I will fix these places, later, to use SilcDList.
6350 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6351 and use TRQ internally).
6353 Also fixed some annoying warning messages that the original TRQ
6354 code generated. Also minor changes to TRQ's Makefile.in.
6356 * Added support for querying by Client ID to both WHOIS and
6357 IDENTIFY commands into server, as required by the protocol.
6359 * Removed method function pointers from SilcBuffer structure. They
6360 weren't used to anything and just increased the context size for
6361 no good reason. This change also made silc_buffer_alloc and
6362 silc_buffer_free functions inline functions.
6364 * Disabled command flooding detection support until it's fixed so
6365 that it accepts commands in but does not execute them more than once
6368 * Added silc_net_localhost(), to return local hostname, into
6369 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6370 that must be initialized before calling silc_client_init.
6372 * Added new function: silc_server_send_notify_on_channels to send
6373 notify messages to all channels client has joined. It is assured
6374 that the message is sent only once per client.
6376 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6377 lib/silcutil/silcutil.[ch] as silc_format function. The new
6378 function is generic and is used by server as well, not only by
6379 the logging routines.
6381 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6382 the provided version string was not acceptable. Added new function:
6383 silc_ske_check_version into lib/silcske/silcske.h. The function
6384 must be implemented by the application (client or server) and it
6385 does not reside in the SKE library. The function checks the version
6386 string remote end sent.
6388 * Added back pointers (to opaque context and to SilcSocketConnection)
6389 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6391 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6392 duplicate packet context structure.
6394 * Changed `notify' client operation to send same arguments as client
6395 receives from server except for ID's. ID's are mapped to correct
6396 ID entry and that is returned. Also, if channel entry is not sent
6397 by server but the notify is for channel the channel entry is sent
6398 to application (otherwise application doesn't know that it is for
6399 channel (library gets it from packet's Destination ID)).
6401 * Added silc_client_remove_from_channels into client library to
6402 remove a client from all channels it has joined to. Used when
6403 received SIGNOFF notify from server. Added also new function
6404 silc_client_replace_from_channels to replace old ID entry with
6405 new ID entry on all channels. Used when received NICK_CHANGE
6408 * Fixed ID Cache list handling in silc_idlist_get_client in
6409 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6410 to get (or query) client by ID.
6412 * Updated TODO list.
6414 * Added connection authentication status message defined by the
6415 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6416 support for these into the code in client and server side.
6418 * Added generic function silc_client_send_command to send any command
6419 with variable argument list. Application should use this function
6420 to send commands if the command functions provided by the library
6421 does not suite for the application's user interface needs.
6423 * Added new `failure' client operation. Application is notified about
6424 received failure packet if client is executing a protocol. In this
6425 case the protocol's execution has failed.
6427 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6428 is required by the protocol.
6430 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6431 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6434 * Added status flag to SilcSKE object to indicate realtime status
6435 of the SKE protocol.
6437 * Application receives now exactly same command reply arguments as
6438 the library receives from server. However, if ID is received the
6439 corresponding ID entry is returned to the application (eg. Client
6440 ID is mapped to correct SilcClientEntry entry and that is returned).
6441 Changed command_reply client operation due to this change.
6443 * Changed all ID's in commands and in command replys as ID Payloads.
6444 Change affected both client and server side codes.
6446 All ID's sent in SILC network (with execption of ID's in SILC
6447 Packet header) are sent in ID Payload to support variable length
6450 * Server now notifies nick changes and notifies all clients on
6451 the channels about the new nickname (about the new Client ID,
6454 * Implemented CMODE command to change channel modes. Supports all
6455 channel modes defined by the protocol specs except ban and invite
6456 lists. (Also, private channel key mode is supported but support for
6457 setting private channel key in client is missing, thus, this mode
6458 has no effect on client side (except that server requires that the
6459 client uses private channel key and normal channel traffic does not
6462 Also, invite mode works per se, but INVITE command does not work
6463 yet correctly, so you can set channel as invite only channel but
6464 inviting clients to the channel does not work (it is yet to be
6465 thought what's the best way to do it).
6467 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6468 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6469 Implemented CUMODE command to change user's mode on the channel.
6470 Supports all modes defined by the protocol specs.
6472 * Added NAMES command reply to return users modes on the channel.
6474 * Removed unnecessary and slow ciphers from lib/silccrypt.
6476 * Set SO_KEEPALIVE option to connection sockets by default.
6478 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6480 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6481 redefined the Notify Payload into protocol specs.
6483 * Added silc_id_payload_parse_id to get ID directly from raw
6486 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6488 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6489 accept searching by Client ID as well.
6491 * Added support for LEAVE and SIGNOFF notify types in client library.
6493 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6494 to parse ID Payload from raw data.
6496 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6498 * Added flags parameter into silc_ske_assemble_security_properties
6499 function in lib/silcske/silcske.[ch].
6501 * Changed notify client operation to fit better for notify messages
6502 sent by server. The notify payload received from server is now
6503 passed to the application (after parsing it to SilcNotifyPayload).
6504 It is application's responsibility to retrieve the arguments
6505 from the payload and show the message the way it wants. The message
6506 sent by server is implementation specific.
6508 * Changed public keys to comply with the protocol specification.
6509 Old public keys are not supported anymore and are not compatible.
6511 * Removed nickname from Channel Payload as the latest draft removed
6512 it. The client must resolve the nickname from the NAMES command
6513 reply received when it joined the channel.
6515 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6517 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6519 * Fixed some errors in protocol specification drafts.
6521 * Created lib/silccore/silcnotify.c to implement Notify Payload
6522 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6523 generic payloads described by protocol specifications. The file
6524 includes implementations for ID Payload and Argument Payload.
6526 * Changed Command Payload implementation to use the new Argument
6527 Payload. Changed command_xxxx_payload to command_payload_xxxx
6528 to comply with SILC coding conventions.
6530 * Added suppport for Argument Payload handling in Notify Payload
6531 implementation as protocol requires it. Added the new support
6532 into server and client lib as well.
6534 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6536 * Added support for multiple nicknames on same channel. [n] is
6537 added locally to the nickname if there are more than one same
6538 nicknames on the channel.
6540 * Server now sends all nicknames that matched WHOIS request.
6541 Client also shows the list received from server.
6543 * Added TOPIC command to client side. User can now set and show
6544 current topic on channel.
6546 * Added MOTD command to client and server. Also, server sends the
6547 motd when client connects to the server.
6549 * Changed version strings to comply ISO 8601.
6551 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6553 * Fixed protocol error handling in client library. It should now
6554 cope even if the SKE fails for some reason.
6556 * Made new protocol specification drafts for submitting to IETF.
6558 * Implemented TOPIC command to server in silcd/command.c.
6560 * Added two new notify types into lib/silccore/silcnotify.h:
6561 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6562 notify nickname change and topic setting/change on a channel.
6564 * API change of command_reply operation in client library. The
6565 application gets now the status type received from server as well.
6567 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6569 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6571 * Cras fixed and optimized the packet handling even further and
6572 it should work now. Minor change to the prototype of function
6573 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6575 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6577 * Added new function into lib/silcutil/silcschedule.[ch]:
6578 silc_schedule_with_fd to select() a specified fd. The function
6579 returns after timeout expires or data arrives or goes. The
6580 function is used by packet routines to wait that all data is
6581 received from network.
6583 * Fixed data reading from network in lib/silccore/silcpacket.c.
6584 The code now assures that all data is read from the fd and then
6585 continues packet processing. This was a bug fix since the code
6586 used to drop some data in some circumstances.
6588 * Added new function into lib/silcclient/client.[ch]:
6589 silc_client_start_key_exchange to start key exchange after
6590 connection has been established to server. The code internally
6591 now uses this funtion but its main purpose was to provide it
6592 for applications that perform their own connecting. After
6593 application has created a connection it merely calls this
6594 function to start the key exchange between client and server.
6595 The library takes care of everything else after that.
6597 Updated also lib/silcclient/README to explain the usage of
6600 * Do not send to application information that connection has
6601 been established. Application gets notified it by connect
6604 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6606 * Applied cras's patch to add silc_schedule_one function. The
6607 function runs scheduler once and returns.
6609 * Fixed the scheduler after cras messed it up. The timeout
6610 handling works now as it's supposed to work.
6612 * Added into lib/silccore/ silcnotify.h to include notify
6613 message types support. Changed silc_server_send_notify*
6614 functions, in server.[ch], to support those new notify types.
6615 Added the support for the notify types into client library,
6616 as well. Added new notify client operation into ops.h in
6619 * Changed silc_server_packet_send_to_channel to send normal
6620 packets instead of just channel message packets. The function
6621 is now used to send the notify packets to channels. It is not
6622 used to send channel message packets anymore, as server never
6625 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6626 va_arg()s as it seems to require it nowadays. I guess, if SILC
6627 is compiled with older va_arg() the new code should work anyway.
6629 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6631 * Splitted core library. Core library (lib/silccore) includes
6632 now only SILC protocol specific core (and common) components.
6633 Created new utility library (lib/silcutil) that includes more
6634 generic purpose stuff. The stuff for util library was taken
6635 from the old core library. This was minor and easy split.
6637 * Created SILC Client Library (lib/silcclient) that includes
6638 implementation of the SILC client without user interface. This
6639 was major move from silc/ directory. The code has been changed
6640 so that it is transparent towards the user interface. The
6641 silc/ directory includes now the same user interface as before
6642 and it uses the new client library. Read lib/silcclient/README.
6643 Basicly, the client library performs everything else related
6644 to SILC except user interface handling. Also, configuration
6645 files are considered to be part of user interface and library
6646 does not handle them.
6648 This change also changed a lot of structures, function naming etc.
6649 Most important change was that SilcClientWindow object was
6650 renamed to SilcClientConnection in the client library. Created
6651 also new file lib/silcclient/ops.h. Also added new files
6652 silc/local_command.[ch] and silc/client_ops.[ch].
6654 All these changes were made to make it easier for user interface
6655 designers to create what ever user interface for the SILC client
6658 It is also expected that the server will be moved to lib
6659 directory as well and SILC Server Library will be created;
6660 sometimes in the future.
6662 * Removed Local commands from lib/silccore/silccommand.h as
6663 they are application specific and new client library does not
6664 handle any of those anymore.
6666 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6667 old client implementation in silc/.
6669 * Added support for callback functions in SILC_LOG_* macros.
6670 Application can now set its own callbacks that will be called
6671 instead of using the default functions that will always print
6672 the debug messages to stderr (or stdout). Also, debugging can
6673 now be disabled by setting silc_debug to FALSE and re-enabled by
6674 setting it to TRUE. Note, that logging will still work even
6675 if debugging is disabled.
6677 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6678 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6679 silc_log_reset_debug_callbacks.
6681 * To enable debugging in silc client one must give now -d
6682 option on command line.
6684 * Changed silc_schedule_init to automatically allocate task queues
6685 if they are not allocated before calling it.
6687 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6689 * Added GMP 3.1 into math library.
6691 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6693 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6694 a channel in SILC network. The packet is used by servers and
6695 routers to notify other routers that user has left a channel.
6696 This little feature was missing until now. Added the feature
6697 to protocol specification as well.
6699 Added functions: silc_server_send_remove_channel_user and
6700 silc_server_remove_channel_user into server.[ch].
6702 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6703 lib/silccore/silcpacket.h. However, they are not implemented
6706 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6708 * Fixed joining to a channel and sending channel messages
6709 between server and router. The channel message sending should
6710 now work inside a cell.
6712 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6714 * Fixed the private message sending between server and router.
6715 The private message sending should now work inside a cell.
6717 * Added silc_server_replace_id into server.[ch] to replace
6718 existing ID in the SILC network.
6720 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6721 and silc_idlist_replace_server_id into idlist.[ch] in server.
6723 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6725 * Fixed the server to server connections. Server can again now
6726 connect to router. Router to router connections probably does
6729 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6731 * Added dynamic protocol registering support. Now protocols can
6732 registered and unregistered on the fly. Patch by cras.
6734 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6736 * Added lib/contrib directory to hold routines that some platforms
6737 don't have but are needed by SILC.
6739 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6740 into lin/contrib to provide getopt() and getopt_long() for
6741 those who don't have it.
6743 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6745 * Added AWAY command to client. When away message is set and
6746 client receives a private message packet the client automatically
6747 replies to the sender with the away message.
6749 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6750 bug seemed to be the cause of recent problems when compiling
6753 * Added version detection support to SKE protocol specification
6754 and added the new changes to the SKE implementation as well.
6755 There were other minor changes in the SKE protocol as well.
6757 Many changes in lib/silcske/silcske.[ch] and in
6758 lib/silcske/payload.[ch].
6760 * Added ^U functionality, clear input line. Patch from cras.
6762 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6764 * Mainly small bugfixes on core library. Fixed some debugging
6765 logging and buffer overflow in silclog.c.
6767 * Updated config.sub and config.guess on the distribution tree.
6769 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6771 * Added command lagging support in server. Client may execute
6772 commands now only once in two seconds.
6774 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6776 * Optimized packet reception. MAC computation and checking is now
6777 also more optimized. A lot previously duplicated code is now
6778 used as generic by both client and server.
6780 * Fixed key pair generation in clientutil.c
6782 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6784 * Added into lib/silccore/silcbufutil.[ch] new function;
6785 silc_buffer_realloc.
6787 * Moved generic packet sending/encryption functions to
6788 lib/silccore/silcpacket.[ch] from client and server. Some
6789 rewriting of the functions.
6791 * Moved all generic packet reception/decryption functions to
6792 lib/silccore/silcpacket.[ch] from client and server. The
6793 packet processing is now much cleaner in both client and server.
6794 These were major changes in both client and server.
6796 * Created many common functions in server to do packet sending.
6797 Previously code were duplicated a lot, this has been removed
6800 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6802 * Rewrote major parts of the ID cache system. Don't know
6803 whether it is better now or not but at least the API is more
6806 * Major rewrite on ID cache stuff on client because of the ID
6807 cache API changes. Added idlist.c to client.
6809 * Also major rewrite on ID cache stuff on server as well.
6810 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6811 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6812 in hand, instead they are all put into the ID cache system now.
6813 All server_idlist_* routines uses ID cache now instead of
6814 traversing its own lists (those lists does not exist anymore).
6815 SilcIDList though still exists. Also, SilcXXXEntry's are
6818 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6820 * Finally made the SKE implementation compliant to the protocol
6821 specification. All mp integers are now binary encoded as
6822 opposed being HEX encoded.
6824 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6827 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6828 functions: silc_[encode/decode]_pem. Also added function
6829 silc_encode_pem_file to PEM encode with newlines ('\n') for
6832 * SILC public keys are now encoded either PEM or binary. Same
6833 option is for private keys as well. By default private keys
6834 are binary encoded and public keys PEM encoded. Silly HEX
6835 encoding were removed.
6837 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6838 function to create fingerprints.
6840 * Fixed a bug in SHA1; does not change the original data anymore.
6842 * Partly implemented INFO command on client and server side.
6843 Fixed CLEAR command. Changes to SERVER command; show current
6844 server(s) when giving command without arguments. Added
6845 VERSION command to client.
6847 * Added check to server that unregistered connections cannot
6848 execute commands (unless it is specificly allowed).
6850 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6852 * Fixed screen refresh.
6854 * Fixed channel joining bug from client. On some circumstances
6855 client tried to join to a channel it had already joined.
6857 * Added public key verification process into client's protocol.c.
6858 The client now verifies the public key from user and saves
6859 it into ~./silc/serverkeys/ directory.
6861 Added into: clientutil.[ch]: silc_client_verify_server_key.
6863 * Changed SKE protocol's silc_ske_initiator_finish function
6864 to accept callback function that verifies the received public
6865 key. Removed old silc_ske_verify_public_key function.
6867 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6869 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6870 silc_pkcs_private_key[_data]_set.
6872 * Made the password and public authentication more cleaner in
6873 server's protocol.c.
6875 * Removed historic and obsolete protocol `channel_auth' from
6876 both client and server.
6878 * Removed wrong way of sending command status messages from
6879 server to client in server's command.c. The old way violated
6880 protocol specification.
6882 Changes to silccore/silccommand.[ch]: removed
6883 silc_command_encode_status_payload -> not needed anymore,
6884 changed silc_command_encode_payload_va to accept extra
6885 argument on variable argument list. The argument type must
6886 now be provided to the function. Also, added new function:
6887 silc_command_encode_reply_payload_va which is same as
6888 normal command_encode_payload_va except command status type
6889 is provided as extra argument.
6891 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6893 * Added ~./silc directory handling. The directory includes the
6894 public and private keys for the client.
6896 Added silc_client_check_silc_dir, silc_client_create_identifier
6897 and silc_client_load_keys.
6899 * Implemented SILC protocol compliant public key. Added public
6900 and private key saving to and loading from files.
6902 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6903 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6904 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6905 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6906 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6908 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6909 silc_pkcs_load_[public/private]_key.
6911 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6913 * Added silc_server_get_route (route.[ch]) to get connection
6914 data for the fastest route for given ID.
6916 * Implemented INVITE command on client and server. The command
6917 were re-defined in the SILC Protocol Specification and the
6918 implementation now complies with the specification.
6920 * Implemented PING command on client and server.
6922 * Implemented NAMES command on client and server. The server side
6923 supports currently only normal server not router server yet.
6924 Some changes to NAMES definition in SILC protocol specification.
6926 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6928 * Implemented LEAVE command on client and server.
6930 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6931 again. This change was made to the protocol as well. Server
6932 should not violate the protocol specification anymore.
6934 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6936 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6937 was tested. SOCKS4 was not but should work anyway.
